Purpose AE37 and GP2 are HER2 derived peptide vaccines. AE37 primarily elicits a CD4+ response while GP2 elicits a CD8+ response against the HER2 antigen. These peptides were tested in a large randomized trial to assess their ability to prevent recurrence in HER2 expressing breast cancer patients. The primary analyses found no difference in 5-year overall disease-free survival (DFS) but possible benefit in subgroups. Here, we present the final landmark analysis. Methods In this 4-arm, prospective, randomized, single-blinded, multi-center phase II trial, disease-free node positive and high-risk node negative breast cancer patients enrolled after standard of care therapy. Six monthly inoculations of vaccine (VG) vs. control (CG) were given as the primary vaccine series with 4 boosters at 6-month intervals. Demographic, safety, immunologic, and DFS data were evaluated. Results 456 patients were enrolled; 154 patients in the VG and 147 in CG for AE37, 89 patients in the VG and 91 in CG for GP2. The AE37 arm had no difference in DFS as compared to CG, but pre-specified exploratory subgroup analyses showed a trend towards benefit in advanced stage (p = 0.132, HR 0.573 CI 0.275–1.193), HER2 under-expression (p = 0.181, HR 0.756 CI 0.499–1.145), and triple-negative breast cancer (p = 0.266, HR 0.443 CI 0.114–1.717). In patients with both HER2 under-expression and advanced stage, there was significant benefit in the VG (p = 0.039, HR 0.375 CI 0.142–0.988) as compared to CG. The GP2 arm had no significant difference in DFS as compared to CG, but on subgroup analysis, HER2 positive patients had no recurrences with a trend toward improved DFS (p = 0.052) in VG as compared to CG. Conclusions This phase II trial reveals that AE37 and GP2 are safe and possibly associated with improved clinical outcomes of DFS in certain subgroups of breast cancer patients. With these findings, further evaluations are warranted of AE37 and GP2 vaccines given in combination and/or separately for specific subsets of breast cancer patients based on their disease biology.

Patient: Male, 62-year-old Final Diagnosis: BCGitis Symptoms: Fever • general fatigue Medication: — Clinical Procedure: Bone marrow biopsy • liver biopsy Specialty: Infectious Diseases • General and Internal Medicine Objective: Rare coexistence of disease or pathology Background: Bladder cancer (BC) is the second most common cancer involving the urinary system. In non-muscle-invading BC, transurethral resection of a bladder tumor followed by intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) is the usual treatment. Disseminated (or systemic) BCG infection (BCGitis) represents the most severe adverse effect of intravesical BCG therapy, presenting with high-grade fever, with or without symptoms in the urinary tract, leading to severe sepsis and death if left untreated. The treatment of choice consists of isoniazid, rifampicin, and ethambutol (with or without corticosteroids) for 6 months, and the recovery rate is extremely high. Given the fact that these drugs are hepatotoxic, treating a patient with liver cirrhosis is challenging. Case Report: We present a patient with a medical history of BC treated with transurethral resection and intravesical BCG therapy, presenting with fever, transaminasemia, and generalized weakness. Liver and bone marrow biopsies revealed liver cirrhosis and granulomas in both organs. A diagnose of BCGitis was made and the patient was treated with isoniazid, rifampicin, and ethambutol; rifampicin was substituted with moxifloxacin after 1 month due to worsening of liver laboratory results, and moxifloxacin was substituted with levofloxacin later on due to tonic-clonic seizures. The patient was treated for 4 more months with levofloxacin and for 7 more months with isoniazid and ethambutol, with no other adverse effects, preserving liver function and achieving cure of BCGitis. Conclusions: We present the case of a cirrhotic patient presenting with fever and deterioration of liver laboratory results, found to have BCGitis, and discuss possible difficulties in diagnosing and treating such patients.

Background Immune‐checkpoint inhibitors have been shown to improve survival in melanoma patients, but can also trigger immune‐related endocrinopathies, especially hypophysitis and thyroid dysfunction. Methods To assess the incidence and the spectrum of endocrinopathies in melanoma patients treated with immunotherapy a prospective observational study was conducted. Forty out of 339 patients, treated with immune‐checkpoint inhibitors, developed endocrinopathies. All patients had hormonal functional tests at screening (before the initiation of immunotherapy) and during follow‐up. Results The total incidence of endocrinopathies was 11.8%, 13.4% due to anti‐PD1/PDL1, 5% due to anti‐CTLA4, and 18.5% due to sequential and/or combination treatment. Twenty‐one patients (6.2%) presented with isolated anterior hypophysitis, eleven (3.2%) with primary thyroid dysfunction and eight (2.4%) with both abnormalities. The most frequent anterior pituitary hormone deficiency was central adrenal insufficiency, followed by central hypothyroidism and hypogonadotrophic hypogonadism. None of the patients with corticotroph axis failure recovered during follow‐up. Endocrinopathies occurred after a median of 22 weeks (range: 4‐156) from treatment initiation. Of note, sequential and/or combination therapy with anti‐CTLA4 and anti‐PD1/anti‐PDL1 led to an almost threefold incidence of hypophysitis compared to either monotherapy. Only one of 120 patients receiving anti‐CTLA4 monotherapy developed primary hypothyroidism. Conclusions Our cohort demonstrated an increased incidence of hypophysitis with anti‐PD1/anti‐PDL1 in contrast to the rarity of primary thyroid dysfunction with anti‐CTLA4 treatment. These results could be attributed to genetic/ethnic differences. Sequential treatment is, for the first time to our knowledge, reported to increase the risk of developing hypophysitis to a level as high as that of combination therapy., A prospective observational study was conducted to assess the incidence and the spectrum of endocrinopathies in 339 melanoma patients treated with immune checkpoint inhibitors. Sequential and/or combination therapy with anti‐CTLA4 and anti‐PD1/anti‐PDL1 led to an almost threefold incidence of hypophysitis compared to either monotherapy, while only one of 120 patients receiving anti‐CTLA4 monotherapy developed primary hypothyroidism.

Simple Summary Despite recent improvements in cure rates, pediatric acute lymphoblastic leukemia (ALL) patients remain at risk to develop relapse disease or suffer from therapy-associated side effects. Over 5% of adverse events appear in the central nervous system (CNS) and can impact survival or quality of life of the patients. Inherited genetic variations are possible predictive factors for these adverse events. This retrospective study aimed to investigate if inherited genetic variations in genes encoding drug-metabolizing enzymes and drug transporters localized in the blood-brain barrier are predictive for CNS events. Our results suggest that certain ABCB1, ABCG2 and GSTP1 gene polymorphisms influence CNS toxicity and CNS relapse. A more effective drug-clearance could lead to less toxicity but contribute to a higher chance of relapse and vice versa. Genetic variants in ABCB1, ABCG2 or GSTP1 genes are promising candidates for personalized medicine. Abstract Despite improving cure rates in childhood acute lymphoblastic leukemia (ALL), therapeutic side effects and relapse are ongoing challenges. These can also affect the central nervous system (CNS). Our aim was to identify germline gene polymorphisms that influence the risk of CNS events. Sixty single nucleotide polymorphisms (SNPs) in 20 genes were genotyped in a Hungarian non-matched ALL cohort of 36 cases with chemotherapy related acute toxic encephalopathy (ATE) and 544 controls. Five significant SNPs were further analyzed in an extended Austrian-Czech-NOPHO cohort (n = 107 cases, n = 211 controls) but none of the associations could be validated. Overall populations including all nations’ matched cohorts for ATE (n = 426) with seizure subgroup (n = 133) and posterior reversible encephalopathy syndrome (PRES, n = 251) were analyzed, as well. We found that patients with ABCB1 rs1045642, rs1128503 or rs2032582 TT genotypes were more prone to have seizures but those with rs1045642 TT developed PRES less frequently. The same SNPs were also examined in relation to ALL relapse on a case-control matched cohort of 320 patients from all groups. Those with rs1128503 CC or rs2032582 GG genotypes showed higher incidence of CNS relapse. Our results suggest that blood-brain-barrier drug transporter gene-polymorphisms might have an inverse association with seizures and CNS relapse.

Objective To assess the predictive value for infection with multidrug-resistant organisms (MDROs) of reasons for empirical prescription of restricted antibiotics (rABX), in a setting with high resistance rates. Methods We prospectively studied all rABX prescriptions in a 550-bed tertiary teaching hospital from April 15 to June 14, 2018 and from September 1 to October 30, 2018. Prescribing physicians had to justify their decision by choosing one or more prespecified reasons. Results We reviewed 172 empirical prescriptions of rABX, which accounted for 67.2% of all rABX prescriptions. Stated reasons for empirical prescription of rABX were recent hospitalization (72.7%), escalation due to non-response to previous antimicrobials (47.7%), treatment for severe sepsis/septic shock (45.9%), escalation due to recurrence or deterioration (22.1%), prior MDRO infection (12.8%), and prior MDRO colonization (7.6%). Empirical treatment for septic shock or severe sepsis was the only significant predictor of MDRO isolation (OR = 5.26, 95% CI: 1.5–18.4, P = 0.009), while recent hospitalization had a high negative predictive value for MDRO (97.4%). Fourteen per cent of microbiologically documented infections were associated with MDROs resistant to the prescribed rABX. Conclusions Empirical treatment for severe sepsis or septic shock was the only independent predictor of MDRO isolation. Recent hospitalization had a high negative predictive value for MDRO infection. The isolation of pathogens resistant to the prescribed rABX suggests that in a setting with widespread antimicrobial resistance, it could be difficult to reduce the empirical use of rABX without risking inadequate treatment.

Introduction: Kounis syndrome (KS) is defined as acute coronary syndrome (ACS) in the context of a hypersensitivity reaction. Patients may present with normal coronary arteries (Type I), established coronary artery disease (Type II) or in-stent thrombosis and restenosis (Type III). Hypothesis: We sought to investigate the clinical presentation, underlying pathophysiology, diagnosis and medical management of patients with KS. Methods: We searched PubMed until 1/1/2020 for case reports of KS. Patients with age Results: Out of the 269 unique patients with KS, 157 (58.4%) had Type I, 64 (23.8%) Type II and 18 (6.7%) Type III while 30 (11.2%) could not be classified. Their mean age was 54.1 years and 190 (70.6%) were male. The majority presented with a combination of cardiac and allergic symptoms [Panel A] and medication was the most commonly reported trigger [Panel B]. Electrocardiographically, 75.1% of cases had ST segment elevation with only 3.3% demonstrating no abnormalities. Coronary imaging was available in 228 (84.8%) patients showing occlusive lesions (32.5%), vascular spasm (16.2%), or normal coronary arteries (51.3%). Percutaneous coronary intervention or coronary artery bypass grafting was performed in 70 (29.4%) of the 238 patients with available information. Conclusions: Hypersensitivity induced ACS is most frequently triggered by medications, and the majority of patients have patent coronary arteries suggesting microvascular dysfunction. KS should be considered in the differential diagnosis of myocardial infarction with non-obstructive coronary arteries.

The epidemiologic correlation of melanoma and chronic lymphocytic leukemia (CLL) has been the subject of several population studies. In the present article, through the presentation of five illustrative cases of patients with melanoma and CLL, several aspects of this complex relationship are highlighted, with a focus on the increased incidence of melanoma in patients with CLL, its speculated etiology, and the impact of CLL stage and disease duration on the incidence and prognosis of melanoma. Furthermore, the rare entity of the synchronous diagnosis of melanoma and CLL in biopsied lymph nodes is discussed, along with its implications on the diagnostic and therapeutic procedures. In addition, the available data on the treatment choices in patients with melanoma and CLL are presented and the efficacy and safety of fludarabine, anti-CD20 monoclonal antibodies, new targeted therapies for CLL, and checkpoint inhibitors are further discussed. Finally, since no formal guidelines are available for the management of this group of patients, guidelines are proposed for skin-cancer screening in patients with CLL, for the correct interpretation of BRAF mutation analysis in lymph-node specimens with ‘collision of tumors,’ and for the optimal use of imaging studies in the diagnosis of metastatic disease in patients with CLL and melanoma, while a treatment approach for such patients is also suggested. The information and proposed guidelines provided in the present article comprise a useful guide for physicians managing such patients, focusing on diagnostic challenges and therapeutic dilemmas posed by the coexistence of the two disease entities.

Immune checkpoint inhibitors (ICI) have altered the prognosis of patients with melanoma over the past few years, with immune-related adverse effects (irAEs) being the only factor limiting their use. Neurologic and cardiac irAEs are rare, but usually severe. We reviewed the files of patients with melanoma treated with ICIs in one center to retrieve data from patients with neurologic irAEs. Patients with a combination of neurologic and cardiac manifestations were further analyzed. We also reviewed the literature for similar syndromes. Five out of 482 (1.01%) patients developed a neurologic syndrome and we present three patients with a constellation of neurologic and cardiac irAEs. A 66-year-old woman and a 68-year-old man presented with a constellation of findings after being treated with ipilimumab and nivolumab, respectively, for melanoma in the adjuvant setting and were eventually diagnosed with myasthenia gravis with cardiac involvement. An 80-year-old woman developed diffuse asymmetric muscle weakness, bilateral ptosis and asymptomatic high serum troponin levels after adjuvant treatment with nivolumab and ipilimumab for a stage IIIB melanoma. After excluding ischemic heart disease, she was diagnosed with axonal polyradiculoneuropathy and myocarditis. Neurologic or cardiac irAEs in patients treated with ICIs are uncommon (

Coronavirus disease 19 (COVID-19) has become a pandemic. Diabetic patients tend to have poorer outcomes and more severe disease (Kumar et al. in Diabetes Metab Syndr 14(4):535–545, 2020. https://doi.org/10.1016/j.dsx.2020.04.044 ). However, the vast majority of studies are representative of Asian and Caucasian population and fewer represent an African-American population. In this single-center, retrospective observational study, we included all adult patients (> 18 years old) admitted to Einstein Medical Center, Philadelphia, with a diagnosis of COVID-19. Patients were classified according to having a known diagnosis of diabetes mellitus. Demographic and clinical data, comorbidities, outcomes and laboratory findings were obtained. Our sample included a total of 355 patients. 70% were African-American, and 47% had diabetes. Patients with diabetes had higher peak inflammatory markers like CRP 184 (111–258) versus 142 (65–229) p = 0.012 and peak LDH 560 (384–758) versus 499 (324–655) p = 0.017. The need for RRT/HD was significantly higher in patients with diabetes (21% vs 11% p = 0.013) as well as the need for vasopressors (28% vs 18% p = 0.023). Only age was found to be an independent predictor of mortality. We found no significant differences in inpatient mortality p = 0.856, need for RRT/HD p = 0.429, need for intubation p = 1.000 and need for vasopressors p = 0.471 in African-Americans with diabetes when compared to non-African-Americans. Our study demonstrates that patients with COVID-19 and diabetes tend to have more severe disease and poorer clinical outcomes. African-American patients with diabetes did not differ in outcomes or disease severity when compared to non-African-American patients.

In the evolving immune-oncology landscape, numerous patients with cancer are constantly treated with immune checkpoint inhibitors (ICPIs) but among them, only sporadic cases with pre-existing hepatitis B virus (HBV) and hepatitis C virus (HCV) are recorded. Despite the global dissemination of HBV and HCV infections, viral hepatitis-infected patients with cancer were traditionally excluded from ICPIs containing trials and current evidence is particularly limited in case reports, retrospective cohort studies and in few clinical trials on advanced hepatocellular carcinoma. Thus, many concerns still remain about the overall oncological management of this special subpopulation, including questions about the efficacy, toxicity and reactivation risks induced by ICPIs. Here, we examine the natural course of both HBV and HCV in cancer environment, review the latest antiviral guidelines for patients undergoing systematic cancer therapies, estimating treatment-related immunosuppression and relocate immunotherapy in this therapeutic panel. Among the ICPIs-treated cases with prior viral hepatitis, we focus further on those experienced HBV or HCV reactivation and discuss their host, tumor and serological risk factors, their antiviral and immunological management as well as their hepatitis and tumor outcome. Based on a low level of evidence, immunotherapy in these specific cancer cases seems to be associated with no inferior efficacy and with a relevantly low reactivation rate. However, hepatitis reactivation and subsequent irreversible complications appeared to have poor response to deferred antiviral treatment. While, the prophylactic use of modern antiviral drugs could eliminate or diminish up front the viral load in most cases, leading to cure or long-term hepatitis control. Taking together the clinical significance of preventive therapy, the low but existing reactivation risk and the potential immune-related hepatotoxicity, a comprehensive baseline assessment of liver status, including viral hepatitis screening, before the onset of immunotherapy should be suggested as a reasonable and maybe cost-effective strategy but the decision to administer ICPIs and the necessity of prophylaxis should always be weighed at a multidisciplinary level and be individualized in each case, up to be established by future clinical trials.

Leukocytes are rapidly recruited to sites of inflammation via interactions with the vascular endothelium. The steroid hormone dehydroepiandrosterone (DHEA) exerts anti-inflammatory properties; however, the underlying mechanisms are poorly understood. In this study, we show that an anti-inflammatory mechanism of DHEA involves the regulation of developmental endothelial locus 1 (DEL-1) expression. DEL-1 is a secreted homeostatic factor that inhibits β2-integrin–dependent leukocyte adhesion, and the subsequent leukocyte recruitment and its expression is downregulated upon inflammation. Similarly, DHEA inhibited leukocyte adhesion to the endothelium in venules of the inflamed mouse cremaster muscle. Importantly, in a model of lung inflammation, DHEA limited neutrophil recruitment in a DEL-1–dependent manner. Mechanistically, DHEA counteracted the inhibitory effect of inflammation on DEL-1 expression. Indeed, whereas TNF reduced DEL-1 expression and secretion in endothelial cells by diminishing C/EBPβ binding to the DEL-1 gene promoter, DHEA counteracted the inhibitory effect of TNF via activation of tropomyosin receptor kinase A (TRKA) and downstream PI3K/AKT signaling that restored C/EBPβ binding to the DEL-1 promoter. In conclusion, DHEA restrains neutrophil recruitment by reversing inflammation-induced downregulation of DEL-1 expression. Therefore, the anti-inflammatory DHEA/DEL-1 axis could be harnessed therapeutically in the context of inflammatory diseases.

We report a 44-year-old male, who was diagnosed with hypogonadotropic hypogonadism after complaining of erectile dysfunction, depression, and fatigue. He was started on testosterone replacement therapy. He persistently complained of fatigue despite increasing the dose of testosterone over two years and having therapeutic testosterone levels. He was found to have homozygous C677T methylenetetrahydrofolate reductase (MTHFR) gene mutation. After treatment with folate and B12, his symptoms resolve completely. MTHFR is a key enzyme in the folate pathway, and it plays an essential role in homocysteine metabolism. Homozygous C677T individuals have decreased activity of MTHFR enzyme with increased homocysteine levels, which is associated with increased risk of thrombosis. An association has been reported between C677T variant and male infertility. Patients identified to have hyperhomocysteinemia should be treated with B-complex vitamin supplements. Our case emphasizes other possible etiologies for fatigue and erectile dysfunction in a male with hypogonadism on testosterone therapy. Also, it shows possible association between MTHFR gene mutation and male hypogonadism.

Objectives The aim of this study was to test the hypothesis that more intensive over standard anticoagulation administered during coronary angiography would significantly reduce rates of radial artery occlusion (RAO). Background RAO, although silent, remains a frequent and therefore worrisome complication following transradial coronary angiography. Anticoagulation is effective in reducing RAO, but the optimal heparin dose remains ill defined. Methods In this multicenter, randomized superiority trial, a high dose (100 IU/kg body weight administered in divided doses) and a standard dose (50 IU/kg body weight) of heparin during 5- or 6-F coronary angiography were compared. A total of 3,102 patients were randomized, of whom 1,836 patients not proceeding to percutaneous coronary intervention and without need for arterial access crossover entered the trial. Post-catheterization hemostasis did not follow a rigid protocol. Results A total of 102 early RAOs were found on ultrasonography (incidence 5.6%). In the high-dose heparin group, the rate of RAO was significantly lower compared with the standard-dose heparin group (27 [3.0%] vs. 75 [8.1%]; odds ratio: 0.35; 95% confidence interval: 0.22 to 0.55; p Conclusions High compared with standard heparin dose significantly reduced the rate of RAO in patients undergoing coronary angiography. High-intensity anticoagulation should be considered in transradial diagnostic procedures.

Background: Ectopic thyroid tissue is a rare entity with a prevalence of 1 per 300,000 persons. Malignancy in ectopic thyroid tissue is reported in Case: A 65-year old woman was incidentally found to have a 3.1 cm mass with coarse calcifications in the superior mediastinum on CT scan of chest. Ultrasound confirmed the presence of hypoechoic mass which was separate from thyroid. Additionally, a 0.5cm TI-Rad 4 left thyroid lobe nodule was found. FNA of the mediastinal mass was suspicious for follicular thyroid neoplasm. Thyramir testing was positive for BRAF V600E and TERT c-124C>T mutations. Thyroid function tests showed frank hyperthyroidism and elevated thyroid stimulating immunoglobulins. Thyroid uptake and scan showed diffuse uptake of 67% at 24 hours. The patient underwent simultaneous excision of mediastinal mass and total thyroidectomy. The pathology of mediastinal mass showed papillary thyroid cancer with tall and sclerosis features with one involved lymph node. The pathology of thyroid gland did not show any malignancy. She was treated with 100 mCi I-131. Post treatment Whole Body Nuclear Scan after treatment revealed metastatic disease in left lower lung area. Discussion: Ectopic thyroid gland is usually found anywhere between forman caecum and mediastinum. It is rare to find ectopic thyroid tissue in the presence of eutopic thyroid gland which can create a diagnostic dilemma. Only a very few case reports of thyroid cancer arising from ectopic thyroid tissue have been reported. Our case is unique as the eutopic thyroid gland had Graves’ disease with no malignancy but the ectopic thyroid tissue developed aggressive papillary thyroid cancer. There are no specific guidelines for the management of carcinoma in ectopic thyroid glands, possibly due to the rarity of the condition. Our case has a clear metastasis to the lungs. However, it is important to differentiate ectopic thyroid tissue with carcinoma from thyroid cancer metastasis which can be difficult at times. Without specific guidelines for the management of cancer in ectopic thyroids, an individualised approach can be taken using the same therapeutic principals used in the management of eutopic thyroid cancer. Additionally, a finding of a normal thyroid gland or a benign condition in the thyroid gland should not exclude the diagnosis of malignancy in ectopic thyroid tissues. 1) Vázquez, Oscar R., et al. “Ectopic papillary thyroid cancer with distant metastasis.” Case reports in endocrinology 2018 (2018).

Immune-related adverse effects (AEs) of PD-1 inhibitors can affect almost every organ, but the skin, intestine, lung, eye, and liver are the most commonly affected organs. Here, we present the case of a 62-year-old female patient with stage IIIc melanoma treated with nivolumab in an adjuvant setting who sequentially developed hyperthyroidism, hypothyroidism, acute hepatitis, and pneumonitis. Six months before the emergence of pneumonitis, the patient had discontinued treatment with nivolumab because of acute hepatitis. Information on pneumonitis after nivolumab discontinuation in the literature is scarce, whereas most of the cases emerge during the first 2.5 months of treatment. Patients with multiple immune-related AEs comprise a group of special interest as the identification of factors affecting the susceptibility of patients to immune-related AEs of PD-1 inhibitors may lead to a more rational use of these drugs. Human leukocyte antigen haplotype and Fcγ receptor polymorphisms are possible targets of the relevant research.

Background Approximately one third of women who develop melanoma at childbearing age are diagnosed during gestation or the postpartum period, facing pregnancy-associated melanoma (PAM). However, only some retrospective studies with heterogeneous data have analyzed the impact of pregnancy on melanoma development, and no evidence exists about the behavior and the management of BRAF-mutated disease. Subjects, Materials, and Methods In order to better describe the evolution of BRAF V600E-mutated PAM, we present here all consecutive cases diagnosed in our site during the last 7 years, recording oncological, obstetrical, and perinatal parameters, as well as the therapeutic decisions for both melanoma and gestation. Based on our institutional experience, we weigh the current published evidence and discuss upcoming clinical considerations about the prognosis of PAM, the role of BRAF status, and the possible treatment options during pregnancy in localized or advanced/metastatic disease. Five women were diagnosed with newly metastatic or relapsed BRAF V600E-mutated PAM (four during gestation and one in the 1st year postpartum) between 2012 and 2019. All of them developed extensive metastatic disease with multiple organ involvement, and four developed brain metastases. All cases experienced melanoma progression in less than 6 months under targeted therapy and died soon independently of the followed sequence of treatments. All the neonates were delivered alive and healthy, but one developed melanoma earlier than the second year of life. Results Reviewing the literature to confirm our unfavorable outcomes, no specific data on BRAF-mutated PAM were retrieved and current evidence still supports that the prognosis of PAM should be guided by the established risk factors, whereas the management of advanced/metastatic PAM should be evaluated on a case-by-case basis. Conclusion More data are required to ascertain whether BRAF-mutated profile adversely affects PAM outcome, although the clinicians should be aware to detect any potential melanoma lesion during pregnancy as soon as possible, treating it locally, regardless of its BRAF status. Implications for Practice The prognosis and management of pregnancy-associated melanoma whether BRAF-mutated or wild type, is currently guided by the same parameters as in the nonpregnant condition. In this special nontrial subpopulation, BRAF-mutated status seems to have a detrimental effect on disease outcome, independently of the following treatments. In early stage melanoma, wide local excision with or without sentinel lymph node dissection may be curative at any trimester of gestation, while in advanced/metastatic setting, therapeutic strategy including immune-checkpoint or BRAF/MEK inhibitors, is more challenging, regardless of BRAF status, and should be based on an individualized decision in each case at a multidisciplinary level.

Immune checkpoint inhibitors (ICBs) have revolutionized cancer treatment producing remarkable and durable responses for a range of malignancies. However, the additional modulation of immune response by ICBs may rarely cause immune-related infectious complications, including re-activation of latent tuberculosis infection (LTBC) with detrimental effects on those patients’ outcome. Here, we present two “real-world” melanoma cases that were treated in our department with blockade of PD-1/PD-L1 and developed active Mycobacterium tuberculosis (MTB) during immunotherapy. In view of these cases, we review the literature for ICB-associated MTB reactivation and discuss our considerations about the possible interactions of immunotherapy and the underlying co-existent mycobacterial infection. Based on the current evidence from preclinical findings prior to this experience, we raise questions regarding cancer patients who are at higher risk for developing MTB infection, whether ICB-treated patients should be considered immunocompromised, and how they should be managed for latent and/or active tuberculosis. Aside from the well-established clinical benefit of immunotherapy, the blockade of PD-1/PD-L1 axis may concurrently disrupt the immune control of specific opportunistic infections such as tuberculosis that should be carefully and expectantly managed in order to avoid compromising the outcome of cancer treatment and the affected patient’s survival.

Background: Hepatitis C (Hep C) infection is one of the leading causes of end stage liver disease and hepatocellular carcinoma. Several advances have been made in the treatment of Hep C infection. Harvoni (ledipasvir and sofosbuvir) is one of the treatment options. There have been no case reports of hypocalcemia or hypoparathyroidism associated with Harvoni therapy. We report a case of hypocalcemia and permanent hypoparathyroidism that began after Harvoni therapy. Case Presentation: A 64-year old African American man presented with weight loss and was diagnosed to have Hep C. He was treated with 12 weeks course of Harvoni. He was first noted to have low calcium level at 8.4 (8.4 – 10.3 mg/dl), during the last week of Harvoni treatment. Several previous calcium levels were normal. Four months later, he presented to Emergency Department with numbness, palpitations, and muscle cramping. His calcium was then 6.6 mg/dl, albumin 4.3 (3.4 - 4.8 mg/dl), PTH 18 (15 - 65 pg/ml), 25-hydroxy vitamin D 11 (30 - 50 ng/ml), magnesium 2.2 (1.6 – 2.6 mg/dl), phosphorus 3.8 (2.3 - 4.7 mg/dl) and 24-hour urine calcium was less than 2. Oral calcitriol, ergocalciferol and calcium carbonate were initiated and his calcium normalized. His calcium remained normal on calcitriol and calcium carbonate, but twice he had to be treated in emergency department for symptomatic hypocalcemia after missing his medications. Recently, he began PTH (1-84) (NATPARA). He has been tolerating parathyroid hormone injections well. Discussion: Harvoni is a combination medication of Ledipasvir and Sofosbuvir. Ledipasvir is a NS5A inhibitor. NS5A is an RNA binding protein required for the activity of RNA polymerase of hepatitis C virus. Sofosbuvir is a viral RNA polymerase inhibitor. There have been no case reports of hypoparathyroidism occurring with Harvoni therapy in the literature. Hypoparathyroidism most commonly results after anterior neck surgery like thyroidectomy, parathyroidectomy, or anterior neck dissection. Other causes include neck irradiation, infections like HIV, infiltration of the glands by heavy metals such as iron or copper; genetic disorders of parathyroid gland development, parathyroid hormone synthesis and calcium sensing receptor mutations, and finally autoimmune etiologies. Our patient had none of the risk factors for developing hypoparathyroidism. Nevertheless, he developed permanent, symptomatic hypoparathyroidism towards the end of Harvoni treatment, making Harvoni as the most likely cause of his hypoparathyroidism. More long-term data on this drug is needed to assess the risk of hypoparathyroidism after Harvoni therapy. Conclusion: Hypoparathyroidism leading to hypocalcemia could be a potential complication of Harvoni treatment. Monitoring calcium and parathyroid hormone levels prior to initiation and periodically after completion of Harvoni treatment should be recommended for all patients.

This retrospective cohort study assessed the prognostic significance of distant metastasis-free interval (DMFI) in patients with relapsed BRAF-mutant melanoma treated with BRAF with or without MEK inhibitors (BRAFi ± MEKi). Patients with a DMFI of up to 24 months were compared with those with DMFI of more than 24 months, with regard to their postrelapse progression-free survival (PR-PFS) and overall survival (PR-OS). In total, 109 patients were included in the study. Median DMFI was 25.3 (range: 3.4-188.2) months. Median PR-PFS in patients with DMFI of more than 24 months was 7.9 months [95% confidence interval (CI): 6.2-9.7] compared with 5.4 (95% CI: 4.2-6.7) months of those with shorter DMFI (P = 0.016). Median PR-OS was 15.6 months (95% CI: 13.6-17.6) in patients with DMFI of more than 24 months and 12.0 months (95% CI: 9.0-15.0) with DMFI of up to 24 months (P = 0.289). Multivariate Cox regression analysis showed that DMFI was independently and strongly associated with improved PR-PFS (adjusted hazard ratio = 3.21, 95% CI: 1.78-5.77, ≤ 24 vs. > 24 months) and longer PR-OS (adjusted hazard ratio: 2.09, 95% CI: 1.15-3.80, ≤ 24 vs. > 24 months). The present cohort study is one of the first to confirm the association of DMFI of more than 24 months with an indolent disease course, as shown by longer PR-PFS and PR-OS, in patients with relapsed stage IV melanoma treated by BRAF inhibitor/MEK inhibitor.

Sarcoidosis and sarcoid-like reactions (SLR) have been repeatedly reported in patients with melanoma treated with BRAF and MEK inhibitors. In the current study we present three patients that developed SLR under treatment with BRAF and mitogen-activated protein kinase (MEK) inhibitors for melanoma. Two patients developed mediastinal lymphadenitis with histological features of an SLR while on targeted therapy in the adjuvant setting, whereas one patient with metastatic melanoma developed granulomatous nephritis while receiving combination treatment with BRAF/MEK inhibitors and atezolizumab. In addition, we review the published literature on the pathogenesis, clinical characteristics, histologic features, imaging findings, and other potential useful diagnostic tools. We also address the need for a common terminology for these cases and propose an algorithm for the accurate diagnosis of BRAF/MEK inhibitor-induced SLR. We also review the currently available data on the treatment of these patients and suggest a treatment approach for SLR in patients with melanoma, as well as for the management of melanoma when SLR emerges.

Background AE37 is the Ii-Key hybrid of the MHC class II peptide, AE36 (HER2 aa:776–790). Phase I studies showed AE37 administered with granulocyte macrophage colony-stimulating factor (GM-CSF) to be safe and highly immunogenic. A prospective, randomized, multicenter phase II adjuvant trial was conducted to evaluate the vaccine's efficacy. Methods Clinically disease-free node-positive and high-risk node-negative breast cancer patients with tumors expressing any degree of HER2 [immunohistochemistry (IHC) 1–3+] were enrolled. Patients were randomized to AE37 + GM-CSF versus GM-CSF alone. Toxicity was monitored. Clinical recurrences were documented and disease-free survival (DFS) analyzed. Results The trial enrolled 298 patients; 153 received AE37 + GM-CSF and 145 received GM-CSF alone. The groups were well matched for clinicopathologic characteristics. Toxicities have been minimal. At the time of the primary analysis, the recurrence rate in the vaccinated group was 12.4% versus 13.8% in the control group [relative risk reduction 12%, HR 0.885, 95% confidence interval (CI) 0.472–1.659, P = 0.70]. The Kaplan–Meier estimated 5-year DFS rate was 80.8% in vaccinated versus 79.5% in control patients. In planned subset analyses of patients with IHC 1+/2+ HER2-expressing tumors, 5-year DFS was 77.2% in vaccinated patients (n = 76) versus 65.7% in control patients (n = 78) (P = 0.21). In patients with triple-negative breast cancer (HER2 IHC 1+/2+ and hormone receptor negative) DFS was 77.7% in vaccinated patients (n = 25) versus 49.0% in control patients (n = 25) (P = 0.12). Conclusion The overall intention-to-treat analysis demonstrates no benefit to vaccination. However, the results confirm that the vaccine is safe and suggest that vaccination may have clinical benefit in patients with low HER2-expressing tumors, specifically TNBC. Further evaluation in a randomized trial enrolling TNBC patients is warranted.

Introduction: Immune checkpoint inhibitors (ICIs) represent an important advance in the treatment of melanoma. ICIs may induce autoimmune phenomena caused by concurrent activation of the immune system against normal cells. During the last years, cases of musculoskeletal side effects, especially immune-mediated arthritis (IA), have been increasingly reported. Patient concerns: We present a 59-year-old woman, who was treated with pembrolizumab for a relapsed BRAF V600E mutated cutaneous malignant melanoma. The patient presented with right knee arthritis on week 30. Diagnosis: The erythrocyte sedimentation rate and serum C-reactive protein levels were elevated, while rheumatoid factor and anti-cyclic citrullinated peptide antibodies were negative. Imaging confirmed the presence of fluid mainly in the suprapatellar bursa. Synovial fluid analysis revealed an inflammatory effusion, while other etiologies of inflammatory arthritis were excluded. Interventions: Arthritis improved with an intra-articular injection of 8 mg dexamethasone. Twelve days later the arthritis relapsed in both knees, and although it was resistant to nonsteroidal anti-inflammatory treatment, it improved with systemic steroids. Tapering of methylprednisolone dose was feasible with the coadministration of leflunomide and subsequently hydroxychloroquine. Outcomes: Arthritis resolved and the patient is free of complications and disease activity 20 months after the initiation of the second line systemic treatment. Conclusions: We present an unusual case of IA associated with pembrolizumab treatment. The originality of the current report is based on the late occurrence, the monoarticular initial distribution, and uncommon location of IA at the knee.

Sickle cell disease (SCD), a hereditary form of chronic hemolytic anemia, is characterized by acute vascular occlusion and chronic complications as pulmonary hypertension (PH), a hallmark of higher mortality. This study aimed to determine peripheral blood expression of superoxide dismutase 2 (SOD2), a major mitochondrial antioxidant enzyme in SCD patients on the mRNA level and compared it with SOD2 expression in healthy individuals. It also aimed to detect possible differences in SOD2 expression among patients with/without specific SCD complications and to detect possible correlations with patient laboratory parameters. SOD2 mRNA levels were significantly lower in SCD patients in comparison with controls and correlated with red blood cell count, reticulocyte count, platelet count, C-reactive protein, ferritin, and brain natriuretic peptide values. SCD patients with echocardiographic indications of PH featured significantly reduced SOD2 expression in comparison with patients without such indications. Consequently, SOD2 expression emerges as a potential biomarker of PH in SCD being a link among hemolysis, inflammation, iron overload, oxidative stress, and SCD cardiopathy.

Radial artery (RA) occlusion (RAO) remains the Achilles heel of transradial coronary procedures. Although of silent nature, RAO is relatively frequent, results in graft shortage for future coronary artery bypass surgery, and may occur even after short-lasting, 5F coronary angiography (CAG). The most frequent predictors of RAO are RA size, body size, female gender, and periprocedural anticoagulation intensity. Methods to detect RAO are variable, of which the Barbeau test and ultrasonography have similar diagnostic accuracy. Data indicate that late RAO recanalization may occur. Meticulous handling of RA and the use of appropriate hemostatic devices and techniques along with sufficient heparin dose appear important measures to reduce RAO rates. Recent contradictory studies indicate that the decreasing incidence of RAO overtime is not as uniform as previously thought. In 2 meta-analyses, the benefit of higher over lower anticoagulation intensity became evident. As “it may all be appropriate anticoagulation” for a simplified approach against RAO, the results of an ongoing trial comparing 100 with 50 IU/kg body weight in transradial CAG are eagerly awaited.

Immune-mediated adverse effects of immune checkpoint inhibitors are rather common, but neuromyopathic immune-related adverse events are very rare. In this report, we present a unique case of a patient with a complex neuromyopathic syndrome with axonal neuropathy and inflammatory myopathy after a single dose of pembrolizumab. An 82-year-old patient with a previously untreated stage IIIc melanoma developed ptosis in the left eye, generalized weakness, and neck and shoulder pain 15 days after pembrolizumab administration. He had left-sided ptosis and miosis, with a normal pupillary light reflex, horizontal diplopia, and voice hoarseness, along with weakness of the neck muscles and a hypokinetic right vocal cord at laryngoscopy. The laboratory evaluation was remarkable for the marked increase in the serum lactate dehydrogenase and creatine phosphokinase levels. Further evaluation revealed findings compatible with axonal neuropathy and inflammatory myopathy. The patient was treated with corticosteroids, immunoglobulin, and plasmapheresis, with a minor response; the patient eventually died. This case represents a newly described syndrome probably associated with pembrolizumab administration.

Background Aortic valve (AV) calcification is the major characteristic of AV sclerosis. Several forms of calcium salts accumulate including hydroxyapatite in late phases. Purpose We sought to examine whether a modified cholesterol – Vitamin D2 diet can produce AV calcification and stenosis in a rabbit model. Methods AV calcification was introduced in New Zealand male rabbits using the modified diet: normal chaw+ 0.5%w/w cholesterol+ 3.500IU Vitamin D2/kg/d (ergocalciferol). Thirty six rabbits were equally randomized into control (normal chaw) and experimental group (modified diet) for 12 weeks. Echocardiography was performed at baseline and the day before the sacrifice. AV Vmax, Transaortic pressure gradient and AV area (AVA) were measured (Vivid 7, GE). AV cusps (collected every 2 weeks, 3 per group) were processed for Fourier-Transformed Infrared Spectroscopy (FT-IR) to detect and characterize calcium salt deposition longitudinally (Nicolet 6700 spectrometer, OMNIC 7.3 software). AVs from surgical patients with severe AV stenosis were used for qualitative comparisons. Results None of the echocardiographic parameters was significantly altered with modified diet; baseline AVA: 0.32 ± 0.06 cm2 vs. 12 weeks: 0.37 ± 0.07, P = 0.18. FT-IR vibrations in the region of 1800-800 cm-1 demonstrated the peroxidation of lipids, advanced glycation end products (AGEs), deposition of CaCO3 and non-hydroxyapatite Ca3 (PO4)2. Further, the 840 cm-1 (HCO3-) band is in accordance to those obtained from human AVs. Conclusion Overall, our rabbit Vitamin D2 model did not produce any AV hemodynamic changes. Interestingly, FT-IR spectroscopy showed that Vitamin D2 stimulated formation of AGEs, deposition of carbonic and phosphate calcium salts in the rabbit AV, both present in human AVs. This study demonstrates that acidosis is an important pathway of AV calcification. Further analysis is needed to elucidate molecular mechanisms in this particular animal model.

Background Tumor immune cell infiltrates are essential in hindering cancer progression and may complement the TNM classification. CD8+ and CD163+ cells have prognostic impact in breast cancer but their spatial heterogeneity has not been extensively explored in this type of cancer. Here, their potential as prognostic biomarkers was evaluated, depending on their combined densities in the tumor center (TC) and the tumor invasive margin (IM). Methods CD8+ and CD163+ cells were quantified by immunohistochemistry of formalin-fixed, paraffin-embedded (FFPE) tumor tissue samples from a cohort totaling 162 patients with histologically-confirmed primary invasive non-metastatic ductal breast cancer diagnosed between 2000 and 2015. Clinical follow-up (median 6.9 years) was available for 97 of these patients. Results Differential densities of CD8+ and CD163+ cells in the combined TC and IM compartments (i.e., high(H)/low(L), respectively for CD8+ cells and the reverse L/H combination for CD163+ cells) were found to have significant prognostic value for survival, and allowed better patient stratification than TNM stage, tumor size, lymph node invasion and histological grade. The combined evaluation of CD8+ and CD163+ cell densities jointly in TC and IM further improves prediction of clinical outcomes based on disease-free and overall survival. Patients having the favorable immune signatures had favorable clinical outcomes despite poor clinicopathological parameters. Conclusions Given the important roles of CD8+ and CD163+ cells in regulating opposing immune circuits, adding an assessment of their differential densities to the prognostic biomarker armamentarium in breast cancer would be valuable. Larger validation studies are necessary to confirm these findings.

Objectives To study the behavior of specific coagulation factors in different types of non-metastatic urological cancers, and to identify their possible role as diagnostic and prognostic markers. Methods This was a prospective controlled study, which included three cancer patient groups and a control group of healthy individuals. The cancer subgroups consisted of renal (n = 44), prostate (n = 56) and bladder cancer (n = 47). We excluded patients receiving anticoagulant therapy, or with significant comorbidity. In all patients, certain coagulation parameters were measured (prothrombin time, international normalized ratio, partial thromboplastin time, D-dimers, fibrinogen, F1 + 2, thrombin–antithrombin complex). Statistical analysis was carried out to explore the association of hemostasis markers with tumor–nodes–metastasis stage, Gleason score, transitional cell carcinoma grade, Fuhrman grade and prostate-specific antigen. Results Our final sample consisted in 58 control patients and 147 patients with urological cancer. We found specific patterns of increased coagulation factors in the different cancers that were statistically significant. Renal cancer showed increased levels of D-dimers, partial thromboplastin time and fibrinogen. D-dimers and fibrinogen were increased in prostate cancer; whereas in bladder cancer, only fibrinogen was elevated. Correlations were found between certain factors and tumor stage and grading, with D-dimers being independently associated with higher tumor grade. Thrombin–antithrombin complex was associated with Gleason score. Furthermore, D-dimers, fibrinogen and F1 + 2 were associated with higher tumor stages (II–IV). Conclusions The coagulation pathway seems to be activated in urological malignancies. Specific panels of coagulation factors might play a role as screening or prognostic tools in earlier stages of renal, prostate and bladder cancer. Further research should also focus on their role in the association of cancer with thromboembolic events.

Background Anterior cruciate ligament (ACL) tear is considered a risk factor for osteoarthritis development. The purpose of our study was to investigate the expression levels of the apoptotic enzyme caspase 3, pro-inflammatory cytokines interleukin-1β (IL-1β) and interleukin-6 (IL-6) and degrading enzyme matrix metalloproteinase 13 (MMP-13), all indicative of cartilage degeneration and osteoarthritis development in patients’ chondrocytes after ACL rupture. Methods We investigated the correlation between grade of cartilage degradation and time from injury or patients’ age. IL-1β, IL-6 and MMP-13 mRNA expression levels were investigated in normal (n = 4) and chondrocytes from patients with ACL rupture (n = 33) using real-time polymerase chain reaction (PCR). Moreover, MMP-13 and caspase-3 protein expression levels were evaluated by western blot analysis. Trend analysis and correlation coefficient were performed to derive the relations between gene expression (MMP13, IL-6, IL-1β) and grading of cartilage defects and between gene expression (MMP13, IL-6, IL-1β) and patients’ age, respectively. Results Correlations were established between grade of cartilage degradation and time from injury. MMP-13, IL-6, IL-1β and caspase 3 expression levels were significantly upregulated in chondrocytes from ACL-deficient knee compared to normal. Among the patients with ACL-deficient knees, a significant upregulation of MMP-13 was observed in patients with ACL-rupture > 18 months from the time of injury to arthroscopy compared to patients with ACL-injury up to 18 months, whereas IL-6 and IL-1β expression was higher in chondrocytes from patients with more than 10 months ACL injury compared to those that underwent surgery within the first 10 months after injury. Νο association was observed between IL-1β, IL-6 and MMP-13 expression levels and cartilage defects or patients’ age. Conclusion Our results showed that increased levels of apoptotic, inflammatory and catabolic factors in chondrocytes are associated with time from injury and could contribute to cartilage degradation and osteoarthritis development after ACL rupture.

BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is a distinct entity with incompletely known predisposing factors. The aim of this study is to describe the incidence, risk factors, clinical course, and outcome of PRES in childhood acute lymphoblastic leukemia (ALL). PROCEDURE Patients aged 1.0 to 17.9 years diagnosed with ALL from July 2008 to December 2015 and treated according to the Nordic Society of Pediatric Hematology and Oncology (NOPHO) ALL2008 protocol were included. Patients with PRES were identified in the prospective NOPHO leukemia toxicity registry, and clinical data were collected from the medical records. RESULTS The study group included 1378 patients, of whom 52 met the criteria for PRES. The cumulative incidence of PRES at one month was 1.7% (95% CI, 1.1-2.5) and at one year 3.7% (95% CI, 2.9-4.9). Older age (hazard ratios [HR] for each one-year increase in age 1.1; 95% CI, 1.0-1.2, P = 0.001) and T-cell immunophenotype (HR, 2.9; 95% CI, 1.6-5.3, P = 0.0005) were associated with PRES. Central nervous system (CNS) involvement (odds ratios [OR] = 2.8; 95% CI, 1.2-6.5, P = 0.015) was associated with early PRES and high-risk block treatment (HR = 2.63; 95% CI, 1.1-6.4, P = 0.033) with late PRES. At follow-up of the PRES patients, seven patients had epilepsy and seven had neurocognitive difficulties. CONCLUSION PRES is a neurotoxicity in the treatment of childhood ALL with both acute and long-term morbidity. Older age, T-cell leukemia, CNS involvement and high-risk block treatment are risk factors for PRES.

The aim of this study was to explore possible differences in the pharmacokinetics (PK) of recombinant factor VIII:C (ReFacto - ReFacto ) in HIV+ vs. HIV- patients and also differences in the chromogenic substrate bioassay (CHS) and one-stage clotting (OSC) methods.Twenty-eight haemophilia A adults (20 HIV- and eight HIV+) were assayed with both the CHS and OSC methods. An average of two and six samples were collected per patient for HIV-/+, respectively, after one, and occasionally two more, prophylactic doses (mean 2,003 IU; range 1,000-4,300 IU). The observations were analysed with the mixed-effects (population) compartmental PK modelling package NONMEM (nonlinear mixed-effects modelling) and the FOCE (first-order conditional estimation) method. Base modelling was performed independently for the CHS and OSC bioassays for comparison, and covariate models and simulation tests were done only for the commonly used OSC bioassay. The final covariate model was validated using the bootstrap method. Monte Carlo simulations were used to estimate the expected probability of exceeding 20%, 40% or 60% of normal factor VIII:C in plasma after a single dose, corresponding to required levels for preventing mild, moderate and life-threatening haemorrhages.One-compartment base-model population PK parameters were [mean parameter (interpatient variability %)] for CHS: clearance (CL) = 2.56 dl h(-1) (33.2%); volume of distribution (V) = 34.8 dl (12.8%); and for OSC: CL = 3.83 dl h(-1) (47.8%), V = 53.7 dl (22.4%). The volumes differed significantly between the CHS and OSC methods (p0.0001), and variabilities were higher for OSC. Nevertheless, the empirical half-lives (t(1/2) = l n (2) x V/CL) were similar for CHS and OSC, [(mean +/- standard deviation (SD)], 9.5 +/- 3 h and 10.2 +/- 4 h, respectively. In covariate modelling with the OSC-derived model, HIV status (VIR) was a significant categorical predictor (p0.005) for V. The final covariate models with OSC were for CL = 3.93 + 0.09 x (WT-75) and for V = 48.6 x (1 + 0.36 x VIR) + 0.55 x (WT-75); therefore, V for the typical HIV+ patient was 36% higher than for the HIV- patient.Both HIV- and HIV+ patients showed 100% success with the 20% threshold at doses20 IU/kg. HIV- patients receiving50 IU/kg had a 100% expected chance of success for all thresholds. HIV+ patients for moderate or life-threatening haemorrhage treatment need 10 IU/kg more than the HIV- patient equivalent to have the same probability of success.

Background: Hyperthyroidism is a common disease in the elderly. Antithyroid medications such as methimazole are one of the few treatment options. Case summary: A 76-year-old white woman presented to the clinic with a 1-week history of fatigue, sleepiness, 7-pound weight loss, and tachycardia. Her blood work showed low levels of thyroid-stimulating hormone and high levels of free thyroxine. Due to persistence of her symptoms, she was hospitalized and started on methimazole 10 mg TID. Six weeks after receiving methimazole for the treatment of hyperthyroidism, she had severe jaundice and itching. Results of her liver function tests showed elevation of her alkaline phosphatase and liver transaminase levels, as well as hyperbilirubinemia, formed mainly of the conjugated fraction. Methimazole-induced cholestatic jaundice was diagnosed. Her symptoms gradually improved after discontinuation of the medication, and plasma bilirubin levels were near normal after 8 weeks without methimazole. Conclusions: We report here a probable association between methimazole use and severe cholestatic jaundice in an elderly hyperthyroid patient. The patient's jaundice was reversed after drug discontinuation. ( Am J Geriatr Pharmacother . 2007;5:236-240).

Background and aim: Postprandial glycaemia and lipaemia are known risk factors for atherosclerosis in type 2 diabetes. Coagulation activation in the postprandial. state also contributes to acceleration of atherosclerosis. Nateglinide is effective in reducing postprandial glycaemia. Its effect on glycaemia may also be beneficial in postprandial lipaemia and coagulation. The aim of this study was to examine the potential effect of a single dose of nateglinide on postprandial triglyceridaemia, coagulation, and fibrinolysis in patients with type 2 diabetes. Methods and results: Ten subjects with type 2 diabetes, treated with diet alone were recruited in a crossover randomized study. In the morning, after a 12- to 14-h fast, each subject received a standard mixed meat (total energy 783 kcal), preceded by one tablet of 120 mg nateglinide or placebo. Venous blood samples were drawn prior to meat consumption and 6 h afterwards for the measurement of plasma glucose, insulin, and C-peptide, lipids, coagulation, and fibrinolysis factors. As expected, there was a significant reduction in postprandial glycaemia after nateglinide administration compared to placebo (P < 0.001). Plasma insulin levels were significantly higher after nateglinide than after placebo (P = 0.002). Nateglinide administration resulted in a lower overall postprandial reduction of tissue-plasminogen activator than placebo (-2.9 ± 1.3 vs. -8.3 ± 3.7 ng/ml h, P = 0.003). In addition, a significant reduction of postprandial plasminogen activator inhibitor-1 was observed in comparison with the baseline values after nateglinide (P = 0.001), although the overall response was not significantly different after nateglinide and placebo (P = 0.31). Plasma concentrations of C-peptide, lipids and the remaining coagulation parameters studied were not different between nateglinide and placebo. Conclusions: Acute nateglinide administration improves postprandial glycaemia and fibrinolytic activity in patients with type 2 diabetes. This combined effect, if confirmed by a long-treatment study, might reduce cardiovascular risk in type 2 diabetes. © 2005 Published by Elsevier Ltd. Nutrition Metabolism and Cardiovascular Diseases

3088 Background: AE37 is a Ii-Key hybrid of the HER2 peptide AE36 (HER2776-790), which stimulates peptide-specific T cells. We have completed the active phase of a prospective, randomized, multi-center, phase II trial of the AE37 vaccine in the adjuvant setting. The primary analysis, performed after a median follow up (f/u) of 25 months (mo), did not show a significant difference in disease free survival (DFS) between vaccinated and control patients (pts). However, demonstrating the efficacy of cancer vaccines may require more time than other therapies, especially in malignancies with relatively late recurrences like breast cancer. Here, we present updated efficacy data after extended f/u in subgroups of pts stratified by clinicopathologic characteristics. Methods: Clinically disease-free, node positive or high-risk node negative pts with any level of HER2 expression were randomized to receive AE37 + GM-CSF (VG) or GM-CSF alone (CG) following standard of care therapy. Pts received 6 monthly intradermal inoculations during the primary vaccine series (PVS) followed by 4 boosters administered every 6 mo. Kaplan Meier and log rank analyses were performed from the time of the first inoculation in pts who completed at least the PVS, according to stage, node status, tumor size, HER2 expression and ER/PR status. Results: There were no clinicopathologic differences between groups in the 298 enrolled pts (VG = 153, CG = 145). The vaccine is safe and well tolerated. After a median f/u of 55 mo, there was a trend toward improved DFS in the VG among stage IIB/III pts (VG, n = 73, DFS 82% vs CG, n = 61, 67%, HR = 0.48, p = 0.06) and those with low HER2 expression (HER2 LE, VG, n = 68, 89% vs CG, n = 66, 51%, HR = 0.47, p = 0.1). Improved DFS in the VG was documented in patients with both stage IIB/III disease and HER2 LE (VG, n = 39, 90% vs CG, n = 38, 32%, HR 0.3, p = 0.02) and triple negative (TNBC) pts (VG, n = 21, 89% vs CG, n = 21, 0%, HR 0.26, p = 0.05). Conclusions: The AE37 vaccine is safe and well tolerated and has statistically significant efficacy in stage IIB/III pts with HER2 LE and in TNBC pts. This justifies further evaluation in a phase III study enrolling stage IIb/III pts not eligible for trastuzumab treatment and the very high risk TNBC group. Clinical trial information: NCT00524277.

A sample of 226 drug-dependent individuals consecutively admitted to treatment in the major therapeutic programmes in Greece were assessed at intake with the EuropASI and SCL-90-R. At 4 to 6 weeks, 173 who were continuing treatment were reasssed with the SCL-90-R and interviewed with the SCID-R and the CIDI. Mean age of the subjects was 28 years, and 82.3% were male. Heroin was the main substance of abuse for the large majority (89.8%). Prevalence of AXIS II personality disorders (PD) was 59.5% and the majority (61.2%) had more than one PD. Cluster B was diagnosed in almost half of the subjects (48.6%), Antisocial Personality Disorder (APD) being the most prevalent (33.5%) type of PD. Subjects with APD had an earlier age of initiation of illicit drug use than those without. Subjects with a PD had twice the odds of having a comorbid AXIS I diagnosis and three times the odds of having a mood disorder than those without a PD. SCL-90-R assessments showed that psychiatric symptoms were significantly reduced in the period between intake and the fourth week in treatment. Somatization, Depression and Anxiety symptoms were however less reduced in subjects with a PD than in those without PD. Dropping out from treatment was more strongly predicted by AXIS I than AXIS II disorders, with an increased probability of dropping out in the presence of current mood disorders, whereas current anxiety disorder predicted treatment retention.

Objective To assess the effect of bone mineral density (BMD) screening on the decision to initiate preventive or therapeutic measures for osteoporosis. Methods We offered low-cost BMD screening by dual-energy x-ray absorptiometry of the lumbar spine and proximal femur in conjunction with National Osteoporosis Week. In an effort to assess whether the availability of the BMD measurements resulted in any medical action by the participants of the screening, we conducted a retrospective telephone survey 9 to 12 months after the screening. Results In response to a newspaper promotion, 350 subjects underwent BMD screening during a 3- to 4-month period. Of these 332 female and 18 male participants, 83% were Caucasian, 10% were Asian, 5% were Hispanic, and 2% were African American. The mean age was 60 ± 11 years (range, 29 to 93). Osteoporosis (T-score ≥ -2.5) was present in 24% and osteopenia (T-score of -1 to -2.49) in 47% of the subjects. A report was sent to the participant and, if requested, also to a specified physician. Of the 350 participants, 249 (238 women and 11 men) responded to the telephone survey. Of these respondents, 63% had sought medical consultation after the BMD screening. Results of the BMD study led to an increase in calcium intake in 32% of female respondents (48% of those with osteoporosis). After BMD measurement, use of osteoporosis therapy approved by the US Food and Drug Administration increased from 38% to 78% of those with osteoporosis. Conclusion These results suggest that low-cost BMD screening is highly effective in increasing awareness of osteoporosis, prompting medical consultation, and initiating measures for prevention and treatment of osteoporosis.

In a prospective observational study, we assessed the relative value of conventional stroke risk factors and emerging markers in the prediction of functional outcome of patients surviving the acute phase of an ischemic non-embolic stroke. All available eligible patients consecutively admitted due to a first-ever acute ischemic non-embolic stroke during a 2-year period were evaluated. In a total of 105 patients (54 males, 51 diabetic) a series of clinical, biochemical and imaging characteristics were recorded, including demographic data, blood pressure, serum glucose, insulin, lipids, inflammatory markers, intima-media thickness of the carotid arteries (IMT), brain damage location and size of the infarct volume. Barthel Activities of Daily Living Index (BI) scale was used to assess the severity of neurological deficit on admission and the functional outcome 6 months after discharge. Brain infarct volume, stroke location in the anterior circulation, age, diabetes mellitus, IMT and plasma interleukin-1beta levels proved to be significant determinants of long-term functional outcome, assessed by BI disability score. ROC curve analyses indicated that the infarct volume is superior to other predictors in the diagnosis of patients with unfavorable functional outcome (BI

Central diabetes insipidus (CDI) is an infrequent complication of neurosarcoidosis (NS). Its presentation may be masked by adrenal insufficiency (AI) and uncovered by subsequent steroid replacement. A 45-year-old woman with a history of NS presented 2 weeks after abrupt cessation of prednisone with nausea, vomiting, decreased oral intake and confusion. She was diagnosed with secondary AI and intravenous hydrocortisone was promptly begun. Over the next few days, however, the patient developed severe thirst and polyuria exceeding 6 L of urine per day, accompanied by hypernatraemia and hypo-osmolar urine. She was presumed to have CDI due to NS, and intranasal desmopressin was administered. This eventually normalised her urine output and serum sodium. The patient was discharged improved on intranasal desmopressin and oral prednisone. AI may mask the manifestation of CDI because low serum cortisol impairs renal-free water clearance. Steroid replacement reverses this process and unmasks an underlying CDI.

Background: The long-term outcome for patients with aggressive non-Hodgkin's lymphoma (NHL) is poor. Consequently; the European Organization for Research and Treatment of Cancer Lymphoma Group designed a prospective randomized trial to investigate whether high-dose chemotherapy plus autologous bone marrow transplantation (ABMT) after standard combination chemotherapy improves long-term survival. Methods: Patients aged 15-65 years with aggressive NHL received three cycles of CHVmP/BV polychemotherapy (i.e., a combination of cyclophosphamide, doxorubicin, teniposide, and prednisone, with bleomycin and vincristine added at mid-cycle). After these three cycles, patients With a complete or partial remission and at that time no lymphoma involvement in the bone marrow were randomly assigned to the ABMT arm (a further three cycles of CHVmP/BV followed by BEAC [i.e., a combination of carmustine, etoposide, cytarabine, and cyclophosphamide] chemotherapy and ABMT) or to the control arm (five more cycles: of CHVVmP/BV). All statistical tests are two-sided. Results: From December 1990 through October 1998, 311 patients (median age = 44 years) were registered and received the first-three cycles of CHVmP/BV, and 194 patients were randomly assigned to the treatment arms. Approximately 70% (140 patients) of these patients were of low or low-intermediate International Prognostic Index (IPI) risk. After a median follow-up of 53 months, an intention-to-treat analysis' Showed a time to disease progression and overall survival: at 5 years of 61% (95% confidence interval [CI] = 51% to 72%) and 68% (95% CI = 57% to 79%), respectively, for the ABMT arm and 56% (95% CI = 45% to 67%) and 77% (95% CI = 67% to 86%), respectively, for the control arm. Differences between arms were not statistically significant. A subset analysis on IPI risk groups, although too small for reliable statistical analysis, yielded similar results. Conclusions: Standard combination therapies remain the best choice for most patients with aggressive NHL, We recommend that patients,vith IPI low or low-intermediate risk not be subjected to high-dose chemotherapy and ABMT as a first-line therapy.
