Objective: To describe determinants of persisting humoral and cellular immune response to the second COVID‐19 vaccination among patients with myeloma. Methods: This is a prospective, observational study utilising the RUDYstudy.org platform. Participants reported their second and third COVID‐19 vaccination dates. Myeloma patients had an Anti‐S antibody level sample taken at least 21 days after their second vaccination and a repeat sample before their third vaccination. Results: 60 patients provided samples at least 3 weeks (median 57.5 days) after their second vaccination and before their third vaccination (median 176.0 days after second vaccine dose). Low Anti‐S antibody levels (<50 IU/mL) doubled during this interval (p =.023) and, in the 47 participants with T‐spot data, there was a 25% increase negative T‐spot tests (p =.008). Low anti–S antibody levels prior to the third vaccination were predicted by lower Anti‐S antibody level and negative T‐spot status after the second vaccine. Independent determinants of a negative T‐spot included increasing age, previous COVID infection, high CD4 count and lower percentage change in Anti‐S antibody levels. Conclusions: Negative T‐spot results predict low Anti‐S antibody levels (<50 IU/mL) following a second COVID‐19 vaccination and a number of biomarkers predict T cell responses in myeloma patients.

Introduction: Late presentation of multiple myeloma (MM) heightens the risk of complication risks, including end-organ damage. This study aimed to: 1) detail the diagnostic journey of MM patients, encompassing symptoms, initial diagnoses, and healthcare professionals met; 2) establish the median duration from symptom onset to MM diagnosis; and 3) examine factors linked to timely MM diagnosis within 12 weeks. Methods: A total of 300 adults self-reporting MM were analysed from the Rare and Undiagnosed Diseases cohort Study (RUDY). The RUDY study is a web-based platform, where participants provide dynamic consent and self-report their MM diagnosis and information about their diagnostic journey. This includes the estimated date of initial potential first symptoms, descriptions of these symptoms, the healthcare professionals they consulted, and other diagnoses received before the MM diagnosis. Descriptive statistics, combinatorial analyses and logistic regression analyses were used to describe and examine the diagnostic journey of individuals with MM. Results: Overall, 52% of the participants reported other diagnoses before MM diagnosis, with musculoskeletal disorders (47.8%), such as osteoporosis, costochondritis, or muscle strains, being the most common. The most prevalent initial reported symptom was back pain/vertebral fractures (47%), followed by chest/shoulder pain, including rib pain and fractures (20%), and fatigue/tiredness (19.7%). 40% of participants were diagnosed by direct referral from primary care to haematology without seeing other healthcare professionals whilst 60% consulted additional specialists before diagnosis. The median time from symptom onset to MM diagnosis was 4 months (IQR 2-10 months, range 0-172). Seeing an Allied Healthcare Professional such as a physiotherapist, chiropractor or an osteopath (OR = 0.25, 95% CI [0.12, 0.47], p <0.001), experiencing infection symptoms (OR = 0.32, 95% CI [0.13, 0.76], p = 0.013), and having chest or shoulder pain (OR = 0.45, 95% CI [0.23, 0.86], p = 0.020) were associated with a lower likelihood of being diagnosed with MM within 12 weeks. Older age (OR = 1.04, 95% CI [1.02, 1.07], p = 0.001) was associated with a higher likelihood of diagnosis within 12 weeks. Discussion: Developing resources for allied health professionals may improve early recognition of MM. [ABSTRACT FROM AUTHOR]

Simple Summary: Myeloma, a blood cancer, is rare and hard to diagnose. People often suffer irreversible organ damage by the time of diagnosis. Myeloma is preceded by a premalignant phase that is easily identifiable on a blood test. Currently, there is no screening for this, because most people do not progress to myeloma. We aimed to inform guidelines and screening by refining our understanding of how patients developing myeloma describe their symptoms and how those symptoms relate to organ damage. We found that patients rarely describe 'bone pain' but simply 'pain'. Low-impact crush fractures of the backbones appear to be under-recognised as abnormal. At least 30% of patients have irreversible organ damage at diagnosis. People who developed myeloma fared better if they had previously been diagnosed to have the premalignant condition. Screening based on certain symptoms, possibly combined with imaging and laboratory results, may speed up the diagnosis of myeloma. Multiple myeloma (MM) patients risk diagnostic delays and irreversible organ damage. In those with newly diagnosed myeloma, we explored the presenting symptoms to identify early signals of MM and their relationships to organ damage. The symptoms were recorded in patients' own words at diagnosis and included diagnostic time intervals. Those seen by a haematologist >6 months prior to MM diagnosis were classified as precursor disease (PD). Most (962/977) patients provided data. Back pain (38%), other pain (31%) and systemic symptoms (28%) predominated. Patients rarely complain of 'bone pain', simply 'pain'. Vertebral fractures are under-recognised as pathological and are the predominant irreversible organ damage (27% of patients), impacting the performance status (PS) and associated with back pain (odds ratio (OR) 6.14 [CI 4.47–8.44]), bone disease (OR 3.71 [CI 1.88–7.32]) and age >65 years (OR 1.58 [CI 1.15–2.17]). Renal failure is less frequent and associated with gastrointestinal symptoms (OR 2.23 [CI1.28–3.91]), age >65 years (OR 2.14 [CI1.28–3.91]) and absence of back pain (OR 0.44 [CI 0.29–0.67]). Patients with known PD (n = 149) had fewer vertebral fractures (p = 0.001), fewer adverse features (p = 0.001), less decline in PS (p = 0.001) and a lower stage (p = 0.04) than 813 with de novo MM. Our data suggest subgroups suitable for trials of 'symptom-directed' screening: those with back pain, unexplained pain, a general decline in health or low-impact vertebral compression fractures.

Infection risk is high in healthcare workers working with COVID-19 patients but the risk in non-COVID clinical environments is less clear. We measured infection rates early in the pandemic by SARS-CoV-2 antibody and/or a positive PCR test in 1118 HCWs within various hospital environments with particular focus on non-COVID clinical areas. Infection risk on non-COVID wards was estimated through the surrogate metric of numbers of patients transferred from a non-COVID to a COVID ward. Staff infection rates increased with likelihood of COVID exposure and suggested high risk in non-COVID clinical areas (non patient-facing 23.2% versus patient-facing in either non-COVID environments 31.5% or COVID wards 44%). High numbers of patients admitted to COVID wards had initially been admitted to designated non-COVID wards (22–48% at peak). Infection risk was high during a pandemic in all clinical environments and non-COVID designation may provide false reassurance. Our findings support the need for common personal protective equipment standards in all clinical areas, irrespective of COVID/non-COVID designation. [ABSTRACT FROM AUTHOR]

Summary: Myeloma patients frequently respond poorly to bacterial and viral vaccination. A few studies have reported poor humoral immune responses in myeloma patients to COVID‐19 vaccination. Using a prospective study of myeloma patients in the UK Rudy study cohort, we assessed humoral and interferon gamma release assay (IGRA) cellular immune responses to COVID‐19 vaccination post second COVID‐19 vaccine administration. We report data from 214 adults with myeloma (n = 204) or smouldering myeloma (n = 10) who provided blood samples at least three weeks after second vaccine dose. Positive Anti‐spike antibody levels (> 50 iu/ml) were detected in 189/203 (92.7%), positive IGRA responses were seen in 97/158 (61.4%) myeloma patients. Only 10/158 (6.3%) patients were identified to have both a negative IGRA and negative anti‐spike protein antibody response. In all, 95/158 (60.1%) patients produced positive results for both anti‐spike protein serology and IGRA. After adjusting for disease severity and myeloma therapy, poor humoral immune response was predicted by male gender. Predictors of poor IGRA included anti‐CD38/anti‐BCMA (B‐cell maturation antigen) therapy and Pfizer‐BioNTech vaccination. Further work is required to understand the clinical significance of divergent cellular response to vaccination. [ABSTRACT FROM AUTHOR]

All patients who had had a previous infection had a robust antibody response to the first dose of COVID-19 vaccine and 60% of patients had an optimal immune response to the first dose of COVID-19 vaccination.

Summary: Multiple myeloma is associated with significant early morbidity and mortality, with considerable end organ damage often present at diagnosis. The Tackling EArly Morbidity and Mortality in Multiple Myeloma (TEAMM) trial was used to evaluate routes to diagnosis in patients with myeloma and the relationship between diagnostic pathways, time to diagnosis and disease severity. A total of 915 participants were included in the study. Fifty‐one per cent were diagnosed by direct referral from primary care to haematology; 29% were diagnosed via acute services and 20% were referred via other secondary care specialties. Patients diagnosed via other secondary care specialties had a longer diagnostic interval (median 120 days vs. 59 days) without an increase in features of severe disease, suggesting they had a relatively indolent disease. Marked intrahospital delay suggests possible scope for improvement. A quarter of those diagnosed through acute services reported >30 days from initial hospital consultation to haematology assessment. Participants diagnosed through acute services had poorer performance status (P < 0·0001) and higher burden of end organ damage (P < 0·0001) with no difference in the overall length of diagnostic pathway compared to those diagnosed by direct referral (median 59 days). This suggests that advanced disease in patients presenting through acute services predominantly reflects disease aggression. [ABSTRACT FROM AUTHOR]

Objective: Myeloma is primarily a disease of the elderly, but older patients experience poorer outcomes. Effective treatments may not be offered to older patients over fears about toxicity, particularly for those with comorbidities. We aimed to characterise the trend in survival disparity between older and younger patients and assess to what extent comorbidity might explain these disparities. Methods: We examined records for 56 010 patients diagnosed with myeloma in England between 1998‐2014. The Hospital Episode Statistics database provided information on comorbidity. Net survival was estimated for each diagnosis period. Adjusted excess hazard ratios for the effect of age were estimated using flexible parametric models. Results: Net survival increased for all age groups over the study period. However, older patients experienced a higher risk of death from their disease consistent between 1998 and 2014. Adjusting for comorbidity made little difference to the estimates. Conclusion: Factors other than comorbidity must explain the poorer survival experience of elderly patients. Treatment data were not examined and should be employed by future population studies. Inconsistent treatment of elderly patients with myeloma may be prevented by further use of pragmatic clinical trials which are inclusive of older adults, and also wider utilisation of frailty scores.

Multiple myeloma (MM) is associated with increased risk of infection, but little is known regarding antibody levels against specific bacteria. We assessed levels of polyclonal immunoglobulin and antibacterial antibodies in patients recruited to the TEAMM trial, a randomised trial of antibiotic prophylaxis at the start of anti-myeloma treatment. Polyclonal IgG, IgA and IgM levels were below the reference range in 71%, 83% and 90% of 838 MM patients at diagnosis. Anti-vaccine targeted tetanus toxoid antibodies were protective in 95% of 193 healthy controls but only 41% of myeloma patients. In healthy controls, protective antibodies against 6/12 pneumococcal serotypes, haemophilus and meningococcus A were present in 67%, 41% and 56% compared to just 15%, 21% and 17% of myeloma patients. By 1 year, myeloma patients IgG levels had recovered for 57% of patients whilst the proportion with protective levels of IgG against thymus-dependent protein antigen tetanus toxoid had changed little. In contrast the proportions of patients with protective levels against thymus independent polysaccharide antigens pneumococcus, haemophilus and meningococcus had fallen from 15 to 7%, 21 to 0% and 17 to 11%. Findings highlight the need for strategies to protect patients against bacterial infections during therapy and vaccination programmes during remission. [ABSTRACT FROM AUTHOR]

The treatment of relapsed aggressive lymphoma remains a challenge. Platinum-containing chemotherapy is standard of care. Gemcitabine/oxaliplatin (Gem-Ox) with or without rituximab (R) is an outpatient regimen with a favorable toxicity profile. This retrospective ‘real world’ study reports outcomes for 44 unselected patients with relapsed/refractory aggressive lymphoma treated with Gem-Ox ± R. 41% had primary refractory disease. The overall response rate (ORR) was 43% with a complete response (CR) of 30%. Response to the prior treatment regimen significantly affected the ORR with only 8% achieving CR if prior remission was <12 months. Grade 3–4 hematological toxicity was common and 22% had febrile neutropenia. Eight patients proceeded to stem cell transplant. Overall, outcomes remain poor with a median overall survival of 8 months. In this high-risk group of patients, Gem-Ox ± R results in similar responses to other more toxic, inpatient regimens and should therefore be considered as second line therapy in relapsed lymphoma.

A growing population of long-term survivors of myeloma is now accumulating the 'late effects' not only of myeloma itself, but also of several lines of treatment given throughout the course of the disease. It is thus important to recognise the cumulative burden of the disease and treatment-related toxicity in both the stable and active phases of myeloma, some of which is unlikely to be detected by routine monitoring. We summarise here the evidence for the key late effects in long-term survivors of myeloma, including physical and psychosocial consequences (in Parts 1 and 2 respectively), and recommend the use of late-effects screening protocols in detection and intervention. The early recognition of late effects and effective management strategies should lead to an improvement in the management of myeloma patients, although evidence in this area is currently limited and further research is warranted.

In November 2014 the International Myeloma Working Group ( IMWG) revised the definition of multiple myeloma, such that asymptomatic patients with newly diagnosed multiple myeloma without any of the traditional ' CRAB' (hyper calcaemia, renal impairment, anaemia, bone disease) end organ damage criteria but with one of three new criteria would be recommended to start treatment. Previously, the standard of care for such patients was expectant management. These three new criteria are: greater than 60% clonal plasma cells on bone marrow biopsy, a serum free light chain ( sFLC) ratio of >100 (the involved sFLC must be >100 mg/l) and greater than one unequivocal focal lesion on advanced imaging (low dose whole body computerized tomography, magnetic resonance imaging, 18F fluorodeoxyglucose positron emission tomography). Although this would appear to affect a small number of patients, the impact of these changes are broad, leading to an increased use of advanced imaging, a debate around the management of patients previously diagnosed with smouldering myeloma, changed terminology and clinical trial design and an extension of the use of biomarkers. For the first time the philosophy of treatment in myeloma will change from treatment initiation only being triggered by overt end organ damage to an era where sub clinical risk factors will also be taken into account.

Abnormalities of the p53 gene are known to confer detrimental effects in chronic lymphocytic leukaemia (CLL) and are associated with short survival. We have used high dose methylprednisolone (HDMP) to treat 25 patients with advanced refractory CLL of whom 45% had p53 abnormalities shown by one or more methods: flow cytometry, fluorescent in situ hybridisation and direct DNA sequencing. Fifteen were resistant to fludarabine and 16 were non-responders to their most recent therapy. Methylprednisolone had a cytotoxic effect on lymphocytes from 95% of cases assessed by an ex vivo apoptotic drug sensitivity index (DSI). HDMP was given alone or in combination with other drugs: vincristine, CCNU, Ara-C, doxorubicin, mitoxantrone and chlorambucil, according to the results of DSI. Three patients were treated twice and each treatment was analysed separately. The overall response rate was 77% with a median duration of 12 months (range 7 –23+). Responders included 5/10 with abnormal p53, of which two achieved nodular PR. Patients with p53 abnormalities fared worse than those with normal p53. There were no differences in response according to whether HDMP was used alone or in combination. Nine of the 22 evaluable patients (3 NR and 6 PR) have died from progressive disease or transformation. Main toxicity was infection in 7/25 patients. Event free and overall survival were significantly better in responders vs non-responders (P>0.0001 and P=0.04 respectively). Patients with a DSI of 100% to steroids had a better overall and event free survival, but this was not statistically significant. This study demonstrates that HDMP alone or in combination with other agents is a useful treatment strategy in refractory CLL including patients with p53 abnormalities. [ABSTRACT FROM AUTHOR]

Local and generalized changes in coagulation may be important in the genesis of vegetations and embolism in infective endocarditis. To characterize such alterations, serial hematological investigations were performed on nine consecutive patients who satisfied the inclusion criteria. Platelet survival was measured by Indium labeling. Acute and convalescent samples were analyzed for fibrinogen, factor VIIIc, antithrombin III (AT III), fibrin/fibrinogen degradation products (FDPs), and platelet aggregation. The results suggest that in the active stage of the disease: (1) hypercoagulability may be caused by a rise in acute phase reactants, (2) an acceleration of coagulation and fibrinolysis may supervene, and (3) in some cases there is a reduction in platelet aggregation, possibly as a result of continued circulation of previously activated 'exhausted' platelets.

It states that some predictors of toxicity enable toxicity to be avoided in a dying patient, but data are sparse regarding intensively treated aggressive B cell lymphoma in elderly patients with very poor PS.

A letter to the editor regarding the dose-related side effects of thalidomide in the treatment of myeloma is presented.

The article discusses the possible role of lenalidomide to control gastrointestinal bleeding in hereditary haemorrhagic telangiectasia (HHT). HHT is an inherited disorder of abnormal blood vessel formation and causes mucous membrane bleeding that progresses in severity with age. With the side effects of thalidomide, a better tolerated drug lenalidomide is being considered as an alternative, focusing on a patient, whose life-threatening bleeding was controlled by it.

The article presents the authors' views on the implications of ultra low dose thalidomide on elderly patients with myeloma. They commented that the improvement in performance status in the responders concurs with emerging data that a response to therapy and diminution in disease bulk improves the quality of life of patients with myeloma. They added that the intake of 25 milligrams of thalidomide may enable patients to continue maintenance treatment longer compared with conventional dose.

Seven cases of thromboembolism were found amongst 23 patients treated with thalidomide for myeloma over a total of 141.5 patient treatment months. Five thromboembolic events were venous (two severe) and two arterial. A historical control of 18 similar patients not given thalidomide had one thromboembolism over 289 months. We found no underlying thrombophilic tendency in the affected patients. We suggest that the thalidomide may predispose to thromboembolism at even lower doses than previously reported (mean dose 150 mg). The two most severe thromboses occurred on 100 mg thalidomide alone, not associated with chemotherapy or glucocorticoids. We raise the possibility that arterial thromboembolism may also occur in association with thalidomide. Some patients continued thalidomide after the event, together with warfarin, with no further thromboembolism. [ABSTRACT FROM AUTHOR]

The article presents two case studies related to multiple myeloma. It mentions that a 75-year-old female has complained of headaches, confusion and fluctuating drowsiness, and neutrophils and platelet count of female were normal after examine with magnetic resonance imaging and cerebral computed tomography. It also mentions a 79-year-old male with immunoglobulin M myeloma was admitted with cough and fever, and states that he was diagnosed with human cryptococcal infection.
