Aims: Here in we evaluated the association between the use of Hydrochlorothiazide (HCTZ) and the risk of NMSC both, basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Background: Even though the use of HCTZ is not linked with the development of serious adverse drug reactions, non-melanoma skin cancer (NMSC) has been reported in patients treated with the drug in recent years, most likely due to its photosensitizing ability. Objective: To evaluate the statistically significant difference (P Methods: We performed a retrospective study on patients referred to general practitioners who developed skin cancer or NMSC whether or not they were treated with antihypertensive drugs. Controls were matched with the test by age and sex. We calculated odds ratios (ORs) for skin cancer and NMSC associated with hydrochlorothiazide using conditional logistic regression. Results: We enrolled 19,320 patients in the present study, out of a total of 10,110 (52.3%) who were treated with antihypertensive drugs. Of 10,110 patients, 3,870 were treated with HCTZ (38.3%). During the study, we failed to report an increased risk of NMSC in HCTZ-treated vs. untreated patients. Gender stratification revealed an OR for NMSC of 1.36 for men and 0.56 for women. We did not find a dose-response relationship between HCTZ use and NMSC. Conclusions: In the present study, we failed to report an association between the use of HCTZ and the development of NMSC.

Background: Hepatitis C Virus (HCV) infection represents a global problem, and it is related to both hepatic and extra-hepatic manifestations (e.g., xerophthalmia). New direct-acting antivirals (DAAs), IFN-free treatments, are commonly used to manage HCV infection. However, the impact of new DAAs on dry eyes (xerophthalmia) is lacking. In this study, we evaluated its incidence in HCV patients and the effect of DAAs on this manifestation. Methods: We performed an observational open-label non-randomized study in HCV patients from 01 April 2018 to 01 June 2020. Results : Patients who satisfied the inclusion criteria underwent clinical and laboratory evaluation, Schirmer's test, and Break-up time test. Enrolled patients were divided in two groups: Group 1: HCV patients with xerophthalmia: 24 patients (16 male and 8 female), HCV-RNA 2,685,813 ± 1,145,698; Group 2: HCV patients without xerophthalmia: 35 patients (19 male and 16 female), HCV-RNA 2,614,757 ± 2,820,433. The follow-ups (3 and 6 months after the enrollment) documented an improvement in both eyes’ manifestations and HCV-infection (HCV-RNA undetected). Conclusion: In conclusion, in this study, we reported that xerophthalmia could appear in HCV patients, and DAAs treatment reduces this manifestation without the development of adverse drug reactions.

Aims: To study the role of cytokines and vascular inflammatory biomarkers in unstable carotid plaque Background: Clinical studies showed that not only the degree of stenosis but also the type of carotid plaque can be responsible for ipsilateral ischemic stroke. Objective: The objective of this study is to suggest a role for vulnerable carotid atherosclerotic disease in the occurrence of ischemic stroke. Methods: PubMed, Embase, Cochrane library, and reference lists have been used to evaluate articles published until February 15, 2021. Results: Several factors may be involved in unstable plaque. Clinical studies support the involvement of brain inflammatory biomarkers as well as cytokines in the unstable carotid plaque. Conclusions: Biomarkers could help to stratify patients with a vulnerable carotid plaque and to personalize the drug treatment. In this review, we briefly discuss the characteristics of vulnerable plaque and the role of biomarkers in the vulnerable carotid plaque.

Background: Chronic obstructive pulmonary disease (COPD) is a complex, progressive respiratory condition characterized by heterogeneous clinical presentations (phenotypes). The aim of this study was to assess the prevalence of the main COPD phenotypes and match each phenotype to the most fitting clinical and lung function profile.Methods: The CLIMA (Clinical Phenotypes in Actual Clinical Practice) study was an observational, cross-sectional investigation involving twenty-four sites evenly distributed throughout Italy. Patients were tentatively grouped based on their history and claimed prevailing symptoms at recruitment: chronic cough (CB, suggesting chronic bronchitis); dyspnoea (possible emphysema components, E); recurrent wheezing (presuming asthma components, A). Variables collected were: anagraphics; smoking habit; history of asthma; claim of >1 exacerbations in the previous year; blood eosinophil count; total blood IgE and alpha1 anti-trypsin (α1-AT) levels; complete lung function, and the chest X-ray report. mMRC, CAT, BCS, EQ5d-5L were also used. The association between variables and phenotypes were checked by Chi-square test and multinomial logistic regression.Results: The CB phenotype was prevalent (48.3%), followed by the E and the A phenotypes (38.8% and 12.8%, respectively). When dyspnea was the prevailing symptom, the probability of belonging to the COPD-E phenotype was 3.40 times higher. Recurrent wheezing was mostly related to the COPD-A phenotype. Lung function proved more preserved in the COPD-CB phenotype. Smoke; n. exacerbations/year; VR, and BODE index were positively correlated with the COPD-E phenotype, while SpO2, FEV1/FVC, FEV1/VC, and FEV1 reversibility were negatively correlated. Lower DLco values were highly probative for the COPD-E phenotype (p

Chronic Venous Disease (CVD) is a common medical condition affecting up to 80% of the general population. Clinical manifestations can range from mild to more severe signs and symptoms that contribute to the impairment of the quality of life (QoL) of affected patients. Among treatment options, venoactive drugs such as diosmin are widely used in the symptomatic treatment in all clinical stages. The aim of this study is to determine the effectiveness of a new formulated diosmin in relieving symptoms and improving QoL in patients suffering from CVD. In this randomized, double-blind, placebo-controlled, multicenter clinical study, CVD patients with a Clinical-Etiology-Anatomy-Pathophysiology (CEAP) classification system between C2 and C4 were randomized to receive a bioavailable diosmin (as μsmin® Plus) 450 mg tablet once daily or a placebo for 8 weeks. Clinical symptoms and QoL were monitored using the measurement of leg circumference, visual analogue scale (VAS) for pain, Global Index Score (GIS) and Venous Clinical Severity Score (VCSS). A total of 72 subjects completed the study. From week 4, leg edema was significantly decreased in the active group (p &lt, 0.001). An improvement in the VAS score was observed in the active group compared to placebo at the end of treatment (p &lt, 0.05). GIS and VCSS scores were significantly improved in the active group at week 8 (p &lt, 0.001). No treatment related-side effects were recorded. The results of this study showed that the administration of low-dose μsmin® Plus was safe and effective in relieving symptoms and improving QoL in subjects with CVD.

Background: Panitumumab is an EGFR inhibitor used for the treatment of metastatic colorectal cancer (mCRC), even if its use is related to skin toxicity. Case Presentation: We report the development of forearm panniculitis in two women during the treatment with Panitumumab (6 mg/Kg intravenous every 2 weeks) + FOLFOX-6 (leucovorin, 5- fluorouracil, and oxaliplatin at higher dosage) for the treatment of mCRC. Results: In both patients, clinical, laboratory and radiological evaluation documented the presence of a local panniculitis, probably related to panitumumab (Naranjo score: 6). Panatimumab discontinuation and antimicrobial + corticosteroid treatment induced a remission of skin manifestations. Conclusion: We reported for the first time the development of panniculitis during Panitumumab treatment, and we documented that the treatment with beta-lactams to either fluoroquinolones or oxazolidinone in the presence of corticosteroid improves clinical symptoms in young patients with mCRC, without the development of adverse drug reactions or drug-drug interactions.

Background:The Ketogenic Diet (KD) promotes metabolic changes and optimizes energy metabolism. It is unknown if microRNAs (miRs) are influenced by KD in obese subjects. The screening of circulating miRs was performed with the FDA approved platform n-counter flex and blood biochemical parameters were dosed by ADVIA 1800. Objectives: The aim of this study was to evaluate mir profile under 6 weeks of biphasic KD in obese subjects. We enrolled 36 obese subjects (18 females and 18 males) in stage 1 of Edmonton Obesity Staging System (EOSS) parameter. Result: Any correlation was found between biochemical parameter and three miRs, hsa-let-7b-5p, hsa-miR-143-3p and hsa-miR-504-5p influenced in an equal manner in both sexes. The KD resulted safe and ameliorate both biochemical and anthropometric factors in obese subjects re-collocating them into stage 0 of EOSS parameters.Conclusion:The miRs herein identified under KD might be a useful tool to monitor low carbohydrate nutritional regimens which reflect indirectly the regulatory biochemical mechanisms and cell signaling that orchestrate metabolic and signaling pathways.

Omalizumab is a humanized monoclonal antibody which binds to human immunoglobulins E (IgE), thus preventing their interactions with both high affinity and low affinity IgE receptors. Therefore, omalizumab is currently recommended for add-on biological therapy of uncontrolled allergic asthma, mainly characterized by type 2 airway eosinophilic inflammation. Because omalizumab has been the first, and for a long time the only available monoclonal antibody for add-on treatment of type 2 asthma, some long-term studies have been published which provide a clear evidence of the therapeutic effectiveness of the anti-IgE pharmacological strategy. Within this context, the present single-centre observational study refers to 15 patients with severe allergic asthma, treated with omalizumab for at least 5 years at the Respiratory Unit of “Magna Græcia” University Hospital located in Catanzaro, Italy. In these asthmatic subjects we observed significant increases in asthma control test (ACT) score, with respect to baseline (14.60 ± 2.97), after 1 year (19.20 ± 2.98; p < 0.0001) and 5 years (21.67 ± 2.38; p < 0.0001) of add-on treatment with omalizumab. More importantly, omalizumab significantly lowered the number of annual asthma exacerbations (baseline: 3.66 ± 2.01) after 1 year (0.83 ± 1.14; p < 0.0001) and 5 years (0.63 ± 0.99; p < 0.0001), respectively. This excellent therapeutic outcome made it possible to drastically decrease the daily oral intake of prednisone (baseline: 22.50 ± 5.17 mg) after 1 year (1.83 ± 4.06 mg; p < 0.0001), as well as after 5 years (1.66 ± 3.61 mg; p < 0.0001). With regard to lung function, omalizumab significantly and persistently enhanced FEV 1 (baseline: 1636 ± 628.4 mL) after 1 year (2000 ± 679.7 mL; p < 0.05) and 5 years (1929 ± 564.8 mL; p < 0.05), respectively. Such relevant clinical and functional improvements were associated with reductions of blood eosinophil counts (baseline: 646.0 ± 458.9 cells/μl), already detectable after 1 year (512.7 ± 327.8 cells/μl; not significant), which reached the threshold of statistical significance after 5 years (326.0 ± 171.8 cells/μl; p < 0.05). Therefore, these real-life data referring to our single-centre observational investigation further corroborate the long-term therapeutic ability of omalizumab to improve several clinical, functional and haematological signatures of severe type 2 asthma.

Nattokinase (NK) is a serine protease enzyme with fibrinolytic activity. Even if it could be used for the treatment of several diseases, no data have been published supporting its use patients who underwent vascular surgery. In this study, we evaluated both the efficacy and the safety of nattokinase (100 mg/day per os) in patients admitted to vascular surgery. Patients were of both sexes, &gt, 18 years of age, with vascular diseases (i.e., deep vein thrombosis, superficial vein thrombosis, venous insufficiency), and naïve to specific pharmacological treatments (anticoagulants or anti-platelets). Patients were divided into three groups. Group 1: patients with deep vein thrombosis, treated with fondaparinux plus nattokinase. Group 2: patients with phlebitis, treated with enoxaparin plus nattokinase. Group 3: patients with venous insufficiency after classical surgery, treated with nattokinase one day later. During the study, we enrolled 153 patients (age 22–92 years), 92 females (60.1%) and 61 males (39.9%, ), and documented that nattokinase was able to improve the clinical symptoms (p &lt, 0.01) without the development of adverse drug reactions or drug interactions. Among the enrolled patients, during follow-up, we did not record new cases of vascular diseases. Attention to patients’ clinical evolution, monitoring of the INR, and timely and frequent adjustment of dosages represent the cornerstones of the safety of care for patients administered fibrinolytic drugs as a single treatment or in pharmacological combination. Therefore, we can conclude that the use of nattokinase represents an efficient and safe treatment able to both prevent and treat patients with vascular diseases.

Purpose To evaluate the efficacy of Lactobacillus paracasei CNCM I-1572 (L. casei DG®) in both prevention of symptomatic recurrences and improvement of quality of life in patients with chronic bacterial prostatitis (CBP). Methods Patients with CBP attending a single Urological Institution were enrolled in this phase IV study. At enrollment, all patients were treated with antibiotics in agreement with EAU guidelines and then were treated with L. casei DG® (2 capsules/day for 3 months). Clinical and microbiological analyses were carried out before (enrollment, T0) and 6 months (T2) after the treatment. Both safety and adherence to the treatment were evaluated 3 months (T1) after the enrollment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostate Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The outcome measures were the rate of symptomatic recurrence, changes in questionnaire symptom scores and the reduction of antibiotic use. Results Eighty-four patients were included. At T2, 61 patients (72.6%) reported a clinical improvement of symptoms with a return to their clinical status before symptoms. A time dependent improvement in clinical symptoms with significant changes in NIH-CPSI, IPSS and QoL (mean difference T2 vs T0: 16.5 ± 3.58; − 11.0 ± 4.32; + 0.3 ± 0.09; p p Conclusions L. casei DG® prevents symptomatic recurrences and improves the quality of life in patients with CBP, reducing the antibiotic use.

Background: Anti-leukotriene anti-(LT) drugs induce a more effective control of asthma in female much more than in male subjects, partially due to genetic factors. However, the well-known correlations between “single nucleotide polymorphism” (SNPs) and asthma are still poor investigated in gender difference. Aims and Objectives: The first aim of this study is to characterize the effectiveness of an anti-LT therapy, in sex-matched asthmatic subjects. The second one is to investigate the distribution of SNPs involved in the LTs pathway in female and male asthmatic patients. Methods: In a prospective cohort study of sex-matched asthmatic subjects, pulmonary function tests (higher forced expiratory volume in 1 second [FEV1], forced vital capacity [FVC]) and asthma control tests [ACT] were performed. The fraction of exhaled nitric oxide (FeNO) and blood levels of both 5- lipoxygenase (5-LO) and LTs were also measured. Moreover, 13 SNPs involved in LTs pathway were genotyped in saliva samples. Results: In the first part of the study, female subjects treated with anti-LT have been better control of the asthmatic symptoms and improvement of pulmonary function, compared with male subjects. Interestingly, treated female patients had significantly lower levels of FeNO compared with male patients in the same group. In the second part of the study, 5-LO, LTs blood levels and SNPs have been evaluated, but need to be confirmed. Conclusions: The better control of asthmatic symptoms, lung function and inflammation in females compared to males induced by anti-LT could potentially reflect a different distribution of SNPs according to sex. This evidence could contribute to the development of personalized asthma therapy.

Background: Matrix metalloproteinases (MMPs) are involved in vascular wall degradation, and drugs able to modulate MMP activity can be used to prevent or treat aneurysmal disease. In this study, we evaluated the effects of statins on MMP-2, MMP-9, and neutrophil gelatinase-associated lipocalin (NGAL) in both plasma and tissue in patients with aneurysmal disease. Methods: We performed a prospective, single-blind, multicenter, control group clinical drug trial on 184 patients of both sexes &gt, 18 years old with a diagnosis of arterial aneurysmal disease. Enrolled patients were divided into two groups: Group I under statin treatment and Group II not taking statins. In addition, 122 patients without aneurysmal disease and under statin treatment were enrolled as a control group (Group III). The expression of MMPs and NGAL in plasma was evaluated using ELISA, while their expression in endothelial tissues was evaluated using Western blot. Results: The ELISA test revealed greater plasma levels (p &lt, 0.01) of MMPs and NGAL in Groups I and II vs. Group III. Western blot analysis showed higher expression (p &lt, 0.01) of MMPs and NGAL in Group II vs. Group I, and this increase was significantly higher (p &lt, 0.01) in patients treated with low potency statins compared to high potency ones. Conclusions: MMPs and NGAL seem to play a major role in the development of aneurysms, and their modulation by statins suggests that these drugs could be used to prevent arterial aneurysmal disease.

Wound healing, especially diabetic ones, is a relevant clinical problem, so it is not surprising that surgical procedures are often needed. To overcome invasive procedures, several strategies with drugs or natural compound are used. Recently, in an experimental study, we described an increase in keratinocyte proliferation after their exposition to quercetin plus oleic acid. In the present clinical study, we evaluated both the clinical efficacy and the safety of nano-hydrogel embedded with quercetin and oleic acid in the treatment of lower limb skin wound in patients with diabetes mellitus (DM). Fifty-six DM patients (28 men and 28 women, mean age 61.7 ± 9.2 years) unsuccessfully treated with mechanical compression were enrolled and randomised to receive an add on treatment with hyaluronic acid (0.2%) or nano-hydrogel embedded with quercetin and oleic acid. The treatment with nano-hydrogel embedded with quercetin and oleic acid significantly (P < .01) reduced the wound healing time, in comparison to hyaluronic acid (0.2%) without developing of adverse drug reactions, suggesting that this formulation could be used in the management of wound healing even if other clinical trials must be performed in order to validate this observation.

Theophylline is a natural compound present in tea. Because of its property to relax smooth muscle it is used in pharmacology for the treatment of airway diseases (ie, chronic obstructive pulmonary disease, asthma). However, this effect on smooth muscle is dose dependent and it is related to the development of side effects. Recently, an increasing body of evidence suggests that theophylline, at low concentrations, also has anti-inflammatory effects related to the activation of histone deacetylases. In this study, we evaluated the effects of theophylline alone and in combination with corticosteroids on human bronchial epithelial cells under inflammatory stimuli. Theophylline administrated alone was not able to reduce growth-stimulating signaling via extracellular signal-regulated kinases activation and matrix metalloproteases release, whereas it strongly counteracts this biochemical behavior when administered in the presence of corticosteroids. These data provide scientific evidence for supporting the rationale for the pharmacological use of theophylline and corticosteroid combined drug. © 2017 Gallelli et al.

Alterations of the immune system are known in eating disorders (EDs), however the importance of cytokine balance in this context has not been clarified. We compared cytokines and growth factors at opposite ends of BMI ranges, in 90 patients classified in relation to BMI, depressive and EDs comorbidities. Serum concentrations of interleukin (IL)-1&alpha, IL-1&beta, IL-2, IL-4, IL-6, IL-8, IL-10, interferon-gamma (IFN-&gamma, ), tumor necrosis factor-alpha (TNF-&alpha, ), monocyte chemoattractant protein-1 (MCP-1), vascular endothelial growth factor (VEGF), and epidermal growth factor (EGF) were determined by a biochip analyzer (Randox Labs). Differences were calculated through ANOVA. Possible predictors of higher cytokine levels were evaluated through regression analysis. IL-1&alpha, IL-10, EGF, and IFN-&gamma, were altered individuals with anorexia nervosa (AN) and binge eating disorder (BED). Night-eating was associated with IL-8 and EGF levels, IL-10 concentrations with post-dinner eating and negatively with sweet-eating, long fasting with higher IFN-&gamma, levels. IL-2 increase was not linked to EDs, but to the interaction of depression and BMI. Altogether, for the first time, IL-1&alpha, were shown to differ between AN and HCs, and between AN and individuals with obesity with or without BED. Only IL-2 was influenced by depression. Dysfunctional eating behaviors predicted abnormal concentrations of IL-10, EGF, IL-8 and IFN-&gamma

Recently, we demonstrated the capability of the ketogenic diet (KD) to influence the microRNA (miR) expression profile. Here, we report that KD is able to normalize miR expression in obese subjects when compared with lean subjects. By applying two different bioinformatics tools, we found that, amongst the miRs returning to comparable levels in lean subjects, four of them are linked to antioxidant biochemical pathways specifically, and the others are linked to both antioxidant and anti-inflammatory biochemical pathways. Of particular interest is the upregulation of hsa-miR-30a-5p, which correlates with the decrease of catalase expression protein in red blood cells.

MicroRNAs (miRs) have emerged as biomarkers of migraine disease in both adults and children. In this study we evaluated the expression of hsa-miR-34a-5p and hsa-miR-375 in serum and saliva of young subjects (age 11 &plusmn, 3.467 years) with migraine without aura (MWA), while some underwent pharmacological treatment, and healthy young subjects were used as controls. miRs were determined using the qRT-PCR method, and gene targets of hsa-miR-34a-5p and hsa-miR-375 linked to pain-migraine were found by in silico analysis. qRT-PCR revealed comparable levels of hsa-miRs in both blood and saliva. Higher expression of hsa-miR-34a-5p and hsa-miR-375 was detected in saliva of untreated MWAs compared to healthy subjects (hsa-miR-34a-5p: p &lt, 0.05, hsa-miR-375 p &lt, 0.01). Furthermore, in MWA treated subjects, a significant decrease of hsa-miR-34a-5p and of hsa-miR-375 was documented in saliva and blood compared to MWA untreated ones. Altogether, these findings suggested thathsa-miR-34a-5p and hsa-miR-375 are expressed equally in blood and saliva and that they could be a useful biomarker of disease and of drug efficacy in patients with MWA.

Osteoarthritis (OA) is characterized by deterioration of the joints and associated with considerable pain and disability. OA is a chronic disease that requires intervention with both non-pharmacological and pharmacological treatment modalities and, inevitably, disease progression may necessitate successive treatments throughout the course of the disease. There is increasing data on the shortfalls of current pharmacological treatment of OA, and safety concerns associated with analgesic therapy use in OA arising from increasing evidence of gastrointestinal, cardiovascular, hepatic and renal adverse events with paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs). Consequently, symptomatic slow-acting drugs for OA (SYSADOAs) may now be considered as a first-line treatment for knee OA, with a particular emphasis placed on the outstanding benefit: risk ratio of pharmaceutical-grade glucosamine and chondroitin sulfate formulations. In this short communication we review recent publications concerned with the safety of paracetamol, NSAIDs and SYSADOAs. Greater understanding of the benefits and limitations of current medications will lead to better disease management in OA. Furthermore, adherence to guideline recommendations across Europe and internationally, such as those from the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO), will promote evidence-based medicine and patient-centric care, ultimately leading to greater physician and patient satisfaction.

The carotid body tumors (CBTs) are relatively rare neoplasms and may present into benign or life threatening malignant forms. Matrix metalloproteinases (MMPs) are often involved in vascular and cancer diseases. Objective of this study is to study the relationship between CBTs and MMPs.We performed a multicenter study on 14 patients with CBTs. All tumors were resected. For each patient, we evaluated the MMPs' levels in both plasma (enzyme-linked immunosorbent assay [ELISA] test) and tissue samples (Western blot analysis). These MMPs' plasma levels were compared with the MMPs' plasma levels of healthy patients.Eleven patients had benign CBTs, whereas 3 patients had malignant CBTs. ELISA findings revealed significant higher levels (P 0.01) of MMP-1, -2, -3, -8, and -9 in patients with paraganglioma with respect to healthy patients. Patients with malignant CBTs showed significantly higher levels (P 0.01) of MMP-1, -2, and -3 compared with patients with benign CBTs.Because this is an exploratory study, the experience on this casuistry showed that MMPs' evaluation may help clinicians and surgeons to formulate a more rapid and clear diagnosis on CBTs' behavior. However, other studies on a large group of patients may be useful to validate these observations.

Objective: To date, the management of patients with chronic bacterial prostatitis (CBP) is not satisfactory, especially in terms of symptoms relief. Here, we evaluated the efficacy and the safety of a combination of serenoa repens, selenium and lycopene extract + bromelain and methylsulfonylmethane extract associated with levofloxacin in patients with CBP. Materials and methods: All patients with clinical and instrumental diagnosis of CBP, admitted to a single Urological Institution from March to June 2015 were enrolled in this phase III study. All enrolled patients were randomized into two groups: Group A received levofloxacin 500 mg o.d. for 14 days associated with lycopene and methylsulfonylmethane; Group B received levofloxacin (500 mg o.d. for 14 days) only. Clinical and microbiological analyses were carried out at the time of admission (T0) and during the followups at 1 month (T1) and 6 months (T2) from the end of the treatment. NIH Chronic Prostatitis Symptom Index (CPSI), International Prostatic Symptom Score (IPSS) and Quality of Well-Being (QoL) questionnaires were used. The main outcome measures were the rate of microbiological cure and the improvement in questionnaire results from baseline at the end of the follow-ups period. Results: Forty patients were enrolled in Group A and 39 in Group B. During the follow-up (T1), we recorded a significant changes in terms of NIH-CPSI and IPSS in Group A (mean difference: 17.6 ± 2.65; 12.2 ± 2.33; p < 0.01; p < 0.05, respectively) and versus Group B at the intergroup analysis (mean difference: -9 ± 1.82; -8.33 ± 1.71; p < 0.05; p < 0.05, respectively). No differences were reported in terms of microbiological findings between the two groups. At the second follow-up visit (T2), questionnaire results demonstrated statistically significant differences between groups (p < 0.001). One patient in Group A (2.5%) and 7 patients (17.9%) in Group B showed a symptomatic and microbiological recurrence (p = 0.02). Conclusions: The combination of serenoa repens, selenium, lycopene + bromelain and methylsulfonylmethane extracts improved the clinical efficacy of levofloxacin in patients affected by CBP without the development of side effects.

Chronic venous disease (CVD) is a common and relevant problem affecting Western people. The role of estrogens and their receptors in the venous wall seems to support the major prevalence of CVD in women. The effects of the estrogens are mediated by three estrogen receptors (ERs): ERα, ERβ, and G protein-coupled ER (GPER). The expression of ERs in the vessel walls of varicose veins is evaluated.In this prospective study, patients of both sexes, with CVD and varicose veins undergoing open venous surgery procedures, were enrolled in order to obtain vein samples. To obtain control samples of healthy veins, patients of both sexes without CVD undergoing coronary artery bypass grafting with autologous saphenous vein were recruited (control group). Samples were processed in order to evaluate gene expression.Forty patients with CVD (10 men [25%], 30 women [75%], mean age 54.3 years [median 52 years, range 33-74 years]) were enrolled. Five patients without CVD (three men, two women [aged 61-73 years]) were enrolled as the control group. A significant increase of tissue expression of ERα, ERβ and GPER in patients with CVD was recorded (p .01), which was also related to the severity of venous disease.ERs seem to play a role in CVD; in this study, the expression of ERs correlated with the severity of the disease, and their expression was correlated with the clinical stage.

Previous clinical studies suggest that intravenous (IV) recombinant tissue plasminogen activator (rt-PA) benefits stroke patients regardless of the underlying etiology. In this study, we assessed the possible differences in response to IV rt-PA between cardioembolic stroke and other stroke subtypes. A total of 303 consecutive stroke ischemic patients (from January 2005 to April 2014) admitted to our Stroke Unit and treated with IV rt-PA were retrospectively reviewed. All patients were classified in two groups: Cardioembolic (CE) and Non-Cardioembolic (NCE). We analyzed a total of 303 patients. Thirty patients died in the first hours after fibrinolysis and no statistically significant differences were found in two groups (14 CE vs 18 N-CE). We observed a significant differences in clinical outcome in terms of symptoms "improvement" (p< 0.01 .2) and symptoms" regression" (p

Chronic venous disease (CVD) and its most frightening complication, chronic venous ulceration (CVU), represent an important socioeconomic burden in the western world. Metalloproteinases have been identified in the pathogenesis of several vascular diseases such as venous problems. The aim of this study was to evaluate a broad range of metalloproteinases, such as matrix metalloproteinases (MMPs), ADAMs (a disintegrin and metalloproteinases) and ADAMTSs (a disintegrin and metalloproteinases with thrombospondin motifs) and their inhibitors, tissue inhibitor of metalloproteinases (TIMPs) and a related protein, neutrophil gelatinase-associated lipocalin (NGAL), in patients with CVD in order to correlate their serum levels with each stage of the disease. We performed a multicenter open-label study that comprised the enrolment of 541 patients with CVD of clinical stages C1-C6, (178 males, 363 females; mean age 57·29, median age 53·72, age range 29-81); 29 subjects without CVD were included in this study (9 males and 20 females; mean age 54·44, median age 50, age range 28-84) as the control group. Enzyme-linked immunosorbent assay (ELISA) was performed for measuring serum levels of proteases and related proteins. The study found that the serum elevation of MMP-2, ADAMTS-1 and ADAMTS-7 appeared to be correlated with the initial stages of CVD, whereas the serum elevation of MMP-1, MMP-8, MMP-9, NGAL, ADAM-10, ADAM-17 and ADAMTS-4 was particularly involved in skin change complications. This study showed that each stage of CVD may be described by particular patterns of metalloproteinases, and this may have therapeutic implications in discovering new targets and new drugs for the treatment of CVD.

Background: Direct-acting Antivirals (DAA) are currently used in the treatment of chronic HCV infection. In patients with renal failure Glecaprevir/Pibrentasvir (genotype 1-6) is recommended for its safety and efficacy. Case Presentation: Although these pharmacological characteristics, an adverse drug reaction (ADR) has been reported during Glecaprevir/Pibrentasvir treatment, such as the development of cholestatic jaundice in an elderly patient with chronic HCV (genotype 2) infection. At examination, patient was jaundiced associated with intense pruritus. Results: Ultrasound and laboratory biochemical tests excluded a liver failure (e.g. liver cancer, and liver lithiasis) or pancreatic cancer while Naranjo probability scale (score 6) suggested an association between cholestatic jaundice and Glecaprevir/Pibrentasvir administration. About 1 month after drug discontinuation, an improvement has been documented in both jaundice and pruritus, with a normalization in bilirubin levels (total bilirubin: 0.96 mg/dL), HCV-RNA was undetected also. It is worth mentioning that although we reported the development of cholestatic jaundice upon treatment with Glecaprevir/Pibrentasvir we recorded a clinical efficacy (HCV-RNA Conclusion: These data support the clinical efficacy of Glecaprevir/Pibrentasvir association in elderly patients, despite the sub-optimal period of treatment.

Post-thrombotic syndrome (PTS) is a condition that can develop in about half of the patients with deep vein thrombosis (DVT) of lower limbs. In the present study, we evaluated the expression of inflammatory biomarkers in the early phases of DVT and their correlation with the onset of PTS. Patients were enrolled after the first episode of DVT and were followed up for 1, 4, 8, 12 and 18 months. At each visit, blood sample was collected to evaluate plasma levels of matrix metalloproteinase (MMP)-1,-2,-3,-7,-8 and -9 MMP inhibitors, TIMP-1,-2, neutrophil gelatinase-associated lipocalin (NGAL) and cytokines TNF-α and IL-6. Analysis included 201 patients [86 males (42·79%) and 115 females (57·21%); average age 56 ± 7 years]. Of the 201 patients, 47 (23·38%; 21 males, 26 females) developed PTS during the follow-up period. The control group was made up of 60 individuals without DVT (22 males and 38 females). High plasma levels of MMPs, NGAL and cytokines were recorded during the acute phase after DVT. Moreover, patients with PTS showed higher levels of MMP-1 and MMP-8 with respect to patients without PTS. There is a close relationship between DVT, the individual risk of PTS and specific biomarkers such as MMPs and other related molecules, which may help guide prevention and therapy based on the patient's individual risk profile, and has to be studied in future.

We describe a 67-year-old man with medical history of focal post-stroke seizure and type 2 diabetes mellitus treated with carbamazepine, clobazam, gliclazide, insulin glargine, and omeprazole we visited for the onset in the last 7 days of asthenia, cough with mucus, breathing difficulty, chest pain, and weight loss. After clinical and laboratory tests, pulmonary tuberculosis was diagnosed, and a treatment with isoniazid, ethambutol, pyrazinamide rifampicin, and pyridoxine was started. Therapeutic drug monitoring of tuberculosis treatment documented that all drugs were in normal therapeutic range. Four days after the beginning of the treatment, we documented the improvement of fever, and three days later the patient showed sleepiness, visual disorder and asthenia. Clinical and pharmacological evaluation suggested a carbamazepine toxicity probably related to a drug interaction (Drug Interaction Probability Scale score = 6). The impossibility to switch carbamazepine for another antiepileptic drug, due to a resistant form of seizure, induced the discontinuation of tuberculosis treatment, resulting in the normalization of serum carbamazepine levels in one day (10 µg/ml) and in the worsening of fever, requiring a new clinical and pharmacological evaluation. The titration dosage of carbamazepine and its therapeutic drug monitoring allowed to continue the treatment with both antitubercular drugs and carbamazepine, without the development of adverse drug reactions. To date, tuberculosis treatment was stopped and clinical evaluation, radiology and microbiology assays documented the absence of tubercular infection and no seizures appeared (carbamazepine dosage 800 mg/bid; serum levels 9.5 µg/ml).

The onset of myalgia is a well-known side effect of cholesterol-lowering statins. Recent studiesa dvanced the hypothesis that reduced vitamin D levels may play a role in the onset of myalgia in statin users and potentially a vitamin D supplementation may be useful in these cases, as suggested by the present case report.A 52-year-old man with a history of smoke and successfully controlled hypertension presented with chest pain and asthenia. He was diagnosed with stable angina pectoris and discharged on atorvastatin. Due to the onset of myalgia, the dosage of atorvastatin was reduced (from 40 mg daily to 20 mg daily) and then atorvastatin was switched to rosuvastatin without symptoms improvement. Switching from rosuvastatin to ezetimibe resulted in pain improvement, but also in plasma lipids increase beyond the normal range. Ezetimibe was switched to rosuvastatin+ analgesic; in the meanwhile a high-performance liquid chromatography (HPLC) analysis showed low levels of 25-hydroxy-vitamin D and 1-25-dihydroxy-vitamin D. Therefore, vitamin D3 was added to rosuvastatin, resulting in pain improvement, decrease of plasma lipids and progressive discontinuation of analgesics. During the follow-up, rosuvastatin was switched to atorvastatin + vitamin D3, with a good control of plasma lipid levels and without the onset of myalgia.

Adefovir dipivoxil is a nucleotide analog reverse transcriptase inhibitor used to treat adult patients affected by HBeAg-positive and HBeAg-negative chronic hepatitis B and with clinical evidence of lamivudine-resistant hepatitis B virus (HBV). Adefovir administered at a dosage of 10 mg/day is generally well tolerated, even if renal toxicity, type Fanconi syndrome, was reported during long-term treatments.We report a case of osteomalacia with Fanconi syndrome and pathologic fracture of the femur related to long-time (67 months) adefovir treatment (10 mg/day) in a patient with compensated hepatitis B virus (HBV) cirrhosis (Child 5A) and with a previous normal renal function (estimated Glomerular Filtration Rate before adefovir = 78.26 ml/min/1.73 m2; during adefovir treatment = 57.38 ml/min/1.73 m2). The patient was switched to entecavir at a dose of 1 mg/day, with both suppression of viremia and improvement of osteomalacia and Fanconi syndrome; the patient’s follow-up is still ongoing after 22 months.

Ischaemia reperfusion (I/R) injury refers to tissue damage caused when blood supply returns to the tissue after a period of ischaemia. Matrix metalloproteinases (MMPs), neutrophil gelatinase-associated lipocalin (NGAL) and cytokines are biomarkers involved in several vascular complications. The aim of this study was to evaluate the role of MMPs, NGAL and inflammatory cytokines in I/R syndrome. We conducted an open label, multicentric, parallel group study, between January 2010 and December 2013. Patients with acute limb ischaemia were enrolled in this study and were divided into two groups: (i) those subjected to fasciotomy and (ii) those not subjected to fasciotomy, according to the onset of compartment syndrome. Plasma and tissue values of MMPs and NGAL as well as plasma cytokines were evaluated. MMPs, NGAL and cytokine levels were higher in patients with compartment syndrome. Biomarkers evaluated in this study may be used in the future as predictors of I/R injury severity and its possible evolution towards post-reperfusion syndrome.

OBJECTIVE: To compare fosfomycin trometamol (FT) and ciprofloxacin (CIP) for antibiotic prophylaxis in transrectal prostate biopsy (TR-PB). PATIENTS AND METHODS: Data for 1109 patients (mean age 66.7 ± 8.45) who underwent TR-PB between March to September 2015 in seven Italian urological institutions were retrospectively reviewed, of which 632 received FT (Group 1) and 477 received CIP (Group 2) for prophylaxis. We reviewed all urine culture results obtained after the procedure, all adverse drug reactions (ADRs) related to the drug and all febrile and/or symptomatic urinary tract infections (UTIs) occurring within 1 month after TR-PB. The rate of symptomatic UTIs and the rate of ADRs were considered the main outcome measures. RESULTS: In the total study population, 72/1109 (6.5 %) patients experienced symptomatic UTIs and among these 11 (0.9 % of total) had urosepsis. Out of 72, 53 (73.6 %) symptomatic UTIs were caused by fluoroquinolone-resistant strains. Out of 632, 10 (1.6 %) patients in Group 1 and 62/477 (12.9 %) patients in Group 2 had symptomatic UTIs (p < 0.001); in particular, 2/632 (0.3 %) patients in Group 1 and 9/477 (1.8 %) patients in Group 2 had urosepsis (p < 0.001). No differences were reported in terms of adverse events (0.6 vs 0.4 %; p = 0.70). A Charlson comorbidity index ≤1 and type of antimicrobial prophylaxis (FT) were found to be associated with a lower probability of symptomatic UTIs in the multivariate model. CONCLUSIONS: Antibiotic prophylaxis with FT for TR-PB had a lower rate of adverse events and a lower rate of symptomatic UTIs as compared with CIP. Fosfomycin trometamol appears as an attractive alternative prophylactic regimen in prostate biopsies.

Background. Cerebral aneurysms are relatively common in adults, with a prevalence ranging between 1% and 5%. Subarachnoid hemorrhage, following aneurismal rupture, is a major cause of death and disability in these patients. Matrix Metalloproteinases (MMPs) and Neutrophil Gelatinase-Associated Lipocalin (NGAL) seem to be involved in the pathogenesis and in the clinical course of aneurysms. In this study, we evaluated the relationship between tissue and plasma levels of MMP-9 and NGAL in patient with ruptured and unruptured middle cerebral artery aneurysms. Methods. An open label study was conducted on 7 patients with middle cerebral aneurysms. Three patients had ruptured aneurysms (Group I) and four patients had unruptured aneurysms (Group II). All patients underwent aneurysm clipping. Plasma levels of MMP-9 and NGAL were evaluated through ELISA Test. During the surgery, biopsies of the aneurysmatic arteries were taken and frozen (- 80°C) for Western blot evaluation of MMPs and NGAL expression. Four healthy volunteers (Group III) represented the control group for ELISA testing. Results. Both plasma MMP-9 and NGAL levels were significantly high in aneurysmatic patients respect to those of control patients, and these levels were higher (P < 0.01) in patients with ruptured aneurysms respect to patients with unruptured aneurysms (P < 0.01). The latest findings were similarly evident in tissue evaluation of MMP-9 and NGAL between ruptured and unruptured aneurysms. Conclusion. This study suggests that MMP-9 and NGAL plasma levels may be useful to predict the clinical course of a cerebral aneurysms in order to evaluate the progression of the disease and the tendency of an aneurysm to rupture.

Pathophysiological events involved in the onset of chronic venous ulceration (CVU) are inflammation, activation of polymorphonucleates (PMNs) and secretion of proteases such as matrix metalloproteinases (MMPs), which degrade extracellular matrix (ECM) that is a support for vascular and tissutal wall. MMPs, neutrophil gelatinase-associated lipocalin (NGAL) and inflammatory cytokines are overexpressed in CVUs and they could play a central role in pathophysiological mechanisms of skin lesion and delayed wound healing. Bioflavonoids, such as diosmin and other compounds, appear to have several provessel function activities including anti-inflammatory, antioxidant and phlebotonic effects and are widely used in the treatment of chronic venous disease (CVD)-related problems. In this article, we evaluated the effects of Axaven(®) , a new nutraceutical on both clinical and molecular parameters in patients with CVUs. During the study period, 83 patients with CVUs of both sexes were enrolled and divided into two groups: group A (treated group): 25 females and 19 males (median age is 67·7 years) received standard treatment (compression therapy and surgical correction of superficial venous incompetence) + Axaven(®) once a day for 8 months as adjunctive treatment. Group B (control group): 24 females and 15 males (median age is 65·2 years) were treated only with basic treatment according to their clinical conditions. In our study, the administration of Axaven(®) in patients with CVUs was able to decrease inflammatory cytokines, MMPs and NGAL, inducing an improvement of both symptoms with an increase of the speed of wound healing.

In this regard, we evaluated the effects of a supplement, Aterofisiol,® containing omega-3 (EPA [eicosapen acid] DHA [docosahexaenoic acid]), vitamin K2, vitamin B6, vitamin B12, oligomeric proanthocyanidins (OPC) and resveratrol on the composition of atherosclerotic plaque and on neurological symptoms in patients with carotid stenosis undergoing carotid endarterectomy.Methods: The study was randomized, prospective, and double-blinded. Eligible patients were of both sexes, with carotid stenosis >70% who underwent endarterectomy. Enrolled patients were randomly allocated to receive either one tablet of acetylsalicylic acid 100 mg (Cardioaspirin®) + one tablet of Aterofisiol every 24 hours or one tablet of Cardioaspirin + one tablet of placebo every 24 hours. Each treatment was started 30 days before the surgery and was stopped 5 days before the surgery. The plaques were removed “en bloc” using standard surgical technique.Results: During the study period, 214 patients (135 men and 79 women) were enrolled for intent-to-treat and randomized in two groups: Group A: 107 patients (68 men and 39 women) were treated with Cardioaspirin + Aterofisiol. Group B: 107 patients (67 men and 40 women) were treated with Cardioaspirin + placebo. At the end of the study, 202 patients participated fully (103 patients in Group A and 99 patients in Group B), making up the protocol evaluation population (94.4%). The mean lipid content of removed plaques was significantly lower (P

Beta blockers are the initial treatment for rate control of supraventricular tachyarrhythmia in patients without a history of myocardial infarction or left ventricular dysfunction. In this article we report the recurrence of atrial fibrillation after switching to the generic formulation of atenolol.

Type II heparin‐induced thrombocytopenia (HIT) represents the most common immune‐mediated adverse drug reaction (ADR), during treatment with unfractionated heparin (UFH) or low molecular weight heparins (LMWHs). The frequency of HIT is about 2–3% in surgical divisions (e.g., Cardiac Surgery and Orthopedics) and about 0.5–1% in medical divisions (e.g., Internal Medicine). HIT can develop in 5–10 days after the beginning of heparin and it is induced by the production of antibodies targeting a molecular complex of both “self” protein, that is platelet factor 4 (PF4), and heparin. This induces platelet activation as well as increased thrombin production, that result in a higher risk of venous or arterial thrombosis. When thrombosis is identified, HIT is called HIT‐ associated thrombosis (HITT). Identification of a decrease in platelet count represents the first step in the diagnosis of HIT. However, other clinical and laboratory tests, such as 4Ts score serotonin‐release assay (SRA) and measurement of heparin/PF4 antibodies, must be also used. 4Ts score is a clinical scoring system used to estimate the pretest probability of HIT1, based on its characteristic features (Thrombocytopenia, Timing, Thrombosis) and absence of oTher explanation(s). 4Ts score (Table 1) is also used in the pharmacological management of HIT: score 3 continue heparin, score >4 change heparin to non‐heparin anticoagulants. Among non‐heparin anticoagulants, only lepirudin and argatroban, direct thrombin inhibitors (DTIs), are approved in the treatment of HIT. Another DTI, bivalirudin, is indicated in patients undergoing percutaneous coronary interventions. Danaparoid, a factor Xa inhibitor, is not currently available in Italy, but it is approved for treatment and prevention of HITT in Canada, continental Europe, Australia, New Zealand, and Japan. Finally, fondaparinux sodium, a synthetic antithrombin‐binding pentasaccharide with exclusive anti‐factor Xa activity, has shown favorable results in HIT, although in Italy it is off‐label for this indication. In this paper, we report a case of HITT during treatment with a LMWH, that was successfully treated with an off‐ label administration of fondaparinux sodium.

Diabetic patients are at high risk of foot ulcerations that may lead to limb amputations with important socio-economic impact. Peripheral vascular disease may be frequently associated in diabetes mellitus type II with its main symptom, intermittent claudication. Many studies reported the known efficacy of cilostazol in treating vascular claudication. Metalloproteinase-9 (MMP-9) seems to be a biochemical marker implicated in chronic wounds and in particular in diabetic foot ulcers. Cilostazol appears to have a lowering effect on MMP-9 levels and this may suggest a beneficial effect in order to prevent or retard the onset of foot ulcer in diabetic patients. In our study, two groups of diabetic patients with peripheral vascular disease were divided into two groups according to the presence of claudication in order to receive cilostazol. Group A (31 patients without claudication) were not eligible to receive cilostazol whereas Group B (47 patients with claudication) received cilostazol administration for 24 weeks (100 mg orally twice daily). Median follow up was of 16 months. During the follow up, 4·25% of patients of Group B and 35·48% of patients of Group A (P < 0·01) showed onset of foot ulceration. Although further randomised and controlled studies are required cilostazol seems to show beneficial effects for primary prevention of diabetic foot ulcers.

Venous ulcers are common, with an overall prevalence of up to 2% in the general population of western countries, and have significant socioeconomic impact. Matrix metalloproteinases (MMPs) are involved in the alteration of extracellular matrix that could lead to venous ulceration. Sixty-four patients with venous ulcers were recruited in a 22-month period. All patients were subjected to the most appropriate treatment considering also the patient's wishes (compression therapy followed or not by vein surgery). Patients were randomised into two groups of 32 persons in each (groups A and B). Patients of group A in addition to the basic treatment, described above, received the administration of oral low doses of doxycycline 20 mg b.i.d. for 3 months, whereas patients of group B received basic treatment only. Healing was assessed by means of direct ulcer tracing with computerised planimetry. Group A showed a higher healing rate compared with group B. In group B, the lower healing rate was related to higher levels of MMP-9; neutrophil gelatinase-associated lipocalin and vascular endothelial growth factor, documented in plasma; wound fluid and biopsies executed and compared between both groups. Pharmacological treatments, as doxycycline administration, which by means of its immunomodulatory and anti-inflammatory actions, through the inhibition of MMP, could improve extracellular matrix functioning and represent a possible solution to support wound healing.

Venous ulcers are related to dysfunctions in extracellular matrix. Both matrix metalloproteinases (MMP) and neutrophil gelatinase-associated lipocalin (NGAL) could play a role in the healing process in patients with chronic venous ulcers. We evaluated the role of MMP-9 and NGAL in the healing process in venous ulceration. We performed an open-label, parallel groups, single clinical center study. Patients with chronic venous leg ulcers represented the test group (Group I), whereas patients without chronic ulcers represented the control group (Group II). In Group I plasma and wound fluid samples were collected at the time of admission, at the time of the surgery, and at the follow-up, while ulcer tissues were taken at the time of the surgery. In Group II, plasma and wound fluid were collected at admission and at the time of the surgery, whereas skin tissues were collected at the time of the surgery. Enzyme-linked immunosorbent assay test was used to evaluate the levels of MMP-9 and NGAL in plasma and wound fluid, whereas Western blot analysis was performed to estimate the expression of MMP-9 and NGAL in tissues. Enzyme-linked immunosorbent assay tests revealed significantly higher levels of MMP-9 and NGAL in both plasma and wound fluid of patients with ulcers compared to patients without ulcers (p

Chronic venous ulceration (CVU) is the major cause of chronic wounds of lower extremities, and is a part of the complex of chronic venous disease. Previous studies have hypothesised that several thrombophilic factors, such as hyperhomocysteinaemia (HHcy), may be associated with chronic venous ulcers. In this study, we evaluated the prevalence of HHcy in patients with venous leg ulcers and the effect of folic acid therapy on wound healing. Eighty-seven patients with venous leg ulcers were enrolled in this study to calculate the prevalence of HHcy in this population. All patients underwent basic treatment for venous ulcer (compression therapy ± surgical procedures). Patients with HHcy (group A) received basic treatment and administered folic acid (1·2 mg/day for 12 months) and patients without HHcy (group B) received only basic treatment. Healing was assessed by means of computerised planimetry analysis. The prevalence of HHcy among patients with chronic venous ulcer enrolled in this study was 62·06%. Healing rate was significantly higher (P < 0·05) in group A patients (78·75%) compared with group B patients (63·33%). This study suggests a close association, statistically significant, between HHcy and CVU. Homocysteine-lowering therapy with folic acid seems to expedite wound healing. Despite these aspects, the exact molecular mechanisms between homocysteine and CVU have not been clearly defined and further studies are needed.

The fixed dose combination of sitagliptin 50 mg and metformin 850 mg (Janumet ® ), is indicated for the treatment of type 2 diabetes mellitus in addition to diet and exercise to improve glycemic control in patients treated with metformin alone. Methods: We report a 69-year-old man with type 2 diabetes that developed sudden loss of eyebrows and eyelashes about 4 months after the beginning of Janumet ® . Clinical and laboratory findings excluded the presence of systemic or skin diseases able to induce these manifestations, while the Naranjo probability scale documented a possible association between the drug and the adverse drug reaction.

Several studies have shown that matrix metalloproteinases (MMPs) and neutrophil gelatinase-associated lipocalin (NGAL) play a central role in the pathophysiology of venous and arterial diseases. Some studies have shown the efficacy of glycosaminoglycans, such as sulodexide (SDX), in treating patients with leg ulcers. The aim of this study was to evaluate clinical effects of SDX and its correlation with MMPs and NGAL expression in patients with mixed arterial and venous leg ulcers. Methods: Patients eligible for this study were of both sexes, older than 20 years, and with a clinical and instrumental diagnosis of mixed ulcer. Results: Fifty-three patients of both sexes were enrolled and divided into two groups by means of randomization tables. Group A (treated group) comprised 18 females and ten males (median age: 68.7 years) treated with standard treatment (compression therapy and surgery) + SDX (600 lipoprotein lipase-releasing units/day intramuscularly) for 15 days followed by SDX 250 lipase-releasing units every 12 hours day orally for 6 months as adjunctive treatment. Group B (control group) comprised 17 females and eight males (median age: 64.2 years) treated with standard treatment only (compression therapy and surgery). The type of surgery was chosen according to anatomical level of vein incompetence: superficial venous open surgery and/or subfascial endoscopic perforating surgery. In all enrolled patients, blood samples were collected in order to evaluate the plasma levels of MMPs and NGAL through enzyme-linked immunosorbent assay. These results were compared to another control group (Group C) of healthy individuals. Moreover, biopsies of ulcers were taken to evaluate the tissue expression of MMPs and NGAL through Western blot analysis. Our results revealed that SDX treatment is able to reduce both plasma levels and tissue expression of MMPs improving the clinical conditions in patients with mixed ulcers. Conclusion: Inhibition of MMPs could represent a possible therapeutic intervention to limit the progression of leg ulceration. In particular, our findings demonstrate the efficacy of SDX in patients with mixed arterial and venous chronic ulcers of the lower limbs.

Introduction. An association between hemorrhoidal disease and matrix metalloproteinases (MMPs) has been described previously. MMPs regulate extracellular structural proteins and tissue remodeling. Neutrophil gelatinase-associated lipocalin (NGAL) is involved in the regulation of MMP activity. The aim of this work was to study the relationship between tissue immunoreactive levels of MMPs and NGAL and different stages of hemorrhoids. Methods. In a multicenter, open-label, prospective study, the population under investigation consisted of 2 groups: group I (with symptomatic hemorrhoids; Goligher grade I–IV) and group II (healthy volunteers). Results. We enrolled 97 patients with hemorrhoids: 21 with grade I hemorrhoids, 37 with grade II, 14 with grade III, and 25 with grade IV. Finally, 90 healthy volunteers (53 males and 37 females; age range, 19–70 years; median, 56) were enrolled in group II. Enzyme-linked immunosorbent assay and Western blot analysis revealed greater levels of immunoreactive MMPs and NGAL in all patients with hemorrhoids. We recorded significantly greater levels of MMP-1 and MMP-3 in grade I and II patients compared with control, and greater levels of MMP-3, MMP-7, MMP-8, and MMP-9 in grade III compared with grade II. MMP-9 and NGAL were particularly increased in patients with grade IV especially in case of thrombosed hemorrhoids. Conclusion. These results provide potentially important insights into the understanding of the natural history of hemorrhoids. MMPs and NGAL play a role in development of disease and may represent molecular markers for the complications such as hemorrhoidal thrombosis. (Surgery 2015)
