Efficacy of interleukin-1 blockade in Schnitzler's syndrome without detectable monoclonal gammopathy: a case-based review
No full textSchnitzler's syndrome (SchS) is a rare autoinflammatory disorder characterized by urticarial rash and monoclonal gammopathy which is currently regarded as IL-1 mediated disease. We present the case of a 21-year-old woman presenting with urticarial rash, arthralgias, and elevated inflammatory markers. She has been suffering these symptoms for 2years and was treated with antihistamines, omalizumab, steroids, and non-steroidal anti-inflammatory drugs (NSAIDs) without success. After an extensive diagnostic workout, we suspected SchS even without monoclonal gammopathy, and started Anakinra 100mg daily with a dramatic response and achieving complete remission after 48h of the beginning of the treatment, so we decided to confirm SchS diagnosis. We performed a search of the literature and found seven more cases of patients diagnosed with SchS without monoclonal gammopathy at the presentation. Five were treated with IL-1 blocking therapies and all achieved remission. We, therefore, prompt the possible role of IL-1 blockade therapy remission as support in diagnosing SchS without monoclonal gammopathy

Biologics for Eosinophilic Granulomatosis with Polyangiitis: one size does not fit all
No full textWe read with great interest the Brief Report "Use of Biologics to Treat Relapsing and/or Refractory Eosinophilic Granulomatosis with Polyangiitis: data from a European Collaborative Study" by Canzian et al, recently published in Arthritis & Rheumatology (1). It probably provides the largest real-life contribution on EGPA and biologic drugs. Despite the increasing evidence on the topic, including clinical trials and real life studies (2,3), identifying the most appropriate biologic treatment still represents a challenge
Permanent Discontinuation of Glucocorticoids in Polymyalgia Rheumatica is Uncommon but May Be Enhanced by Amino Bisphosphonates
No full textThe duration of treatment with glucocorticoids (GC) in polymyalgia rheumatica (PMR) is often longterm. Amino bisphosphonates (N-BP) are used in PMR for the prevention of GC-induced osteoporosis, but they could also have immunomodulatory properties. Whether they can be effective as an adjuvant treatment in PMR is unknown. We aimed to establish whether the use of N-BP in our PMR cohort may be associated with GC discontinuation
The Emerging Roles of Endocrine Hormones in Different Arthritic Disorders
No full textThe relationship between endocrine hormones and the spectrum of rheumatic conditions has long been discussed in the literature, focusing primarily on sexual hormones, such as estrogens, androgens, prolactin (PRL). Estrogens are indeed involved in the pathogenesis of the main inflammatory arthritis thanks to their effects on the immune system, both stimulatory and inhibitory. The PRL system has been discovered in synovial tissue of rheumatoid arthritis (RA) and psoriatic arthritis (PsA), patients and has been propose as a new potential therapeutic target. Besides sexual hormones, in the last years scientific interest about the crosstalk of immune system with other class of hormones has grown. Hormones acting on the bone tissue (i.e. parathyroid hormone, vitamin D) and modulators of the Wnt pathway (i.e. Dickkopf-1) have been demonstrated to play active role in inflammatory arthritis course, defining a new field of research named osteoimmunology. PTH, which is one of the main determinants of Dkkopf-1, plays a crucial role in bone erosions in RA and a correlation between PTH, Trabecular Bone Score (TBS) and disease activity has been found in ankylosing spondylitis (AS). In PSA is under studying the interaction among IL-17 and bone metabolism. The purpose of this review is to discuss and summarize the recent data about the interaction between endocrine hormone and immune system in the main rheumatic disorders, covering in particular the role of bone-related hormones and cytokines. We will describe this relationship from a biochemical, diagnostic and therapeutic perspective, with a particular focus on RA, PsA and AS
Factors associated with referral for osteoporosis care in men: a real-life study of a nationwide dataset
No full textIn the present observational cohort study in 4902 men and 9804 women, we found that the factors associated with osteoporosis care utilization in men were comorbidities, adjuvant hormonal therapy for prostate cancer, vertebral or hip fractures, and glucocorticoid treatment.INTRODUCTION: Male osteoporosis is associated with an important clinical and economic burden worldwide; nevertheless, undertreatment of men with osteoporosis is common. Understanding the factors associated with referral to bone specialists may help to define future interventions to improve access to osteoporosis care for male patients.METHODS: We conducted a retrospective analysis of a nationwide cohort (DeFRACalc79 database). DeFRACalc79 is a tool that estimates the fracture risk by considering clinical and densitometric risk factors, including the presence of prior hip or vertebral and non-vertebral or non-hip fractures. We compared the clinical characteristics of male individuals with an age-matched cohort of women. Propensity score generation with a 2:1 female-to-male ratio was performed using a logistic regression model to age-match the cohorts.RESULTS: We analyzed a sample of 4902 men at high risk for osteoporosis. We found that the factors associated with osteoporosis care utilization in men were the presence of comorbidities (OR 1.939, 95% CI 1.799-2.090), adjuvant hormonal therapy for prostate cancer (OR 1.482, 95% CI 1.315-1.670), the presence of vertebral or hip fractures (OR 1.490, 95% CI 1.378-1.611), and glucocorticoid treatment (OR 2.573, 95% CI 2.274-2.832).CONCLUSIONS: Men are more commonly referred to the bone specialist with a prevalent fragility fracture and/or diagnosis of secondary osteoporosis as compared with women. Our study suggests that there is a lack of screening for the primary prevention of osteoporosis in men as compared with that in women
Rituximab increases peripheral natural killer cells in patients with rheumatoid arthritis
No full textObjective The clinical response of rituximab (RTX) is related to the degree of B cell depletion, although other circulating lymphocytes may be affected. We investigated the changes in lymphocyte sub-populations in rheumatoid arthritis (RA) patients treated with RTX and their relationship with the therapeutic response, with attention to natural killer (NK) cells. Methods In fifty-one RA patients peripheral blood B and T lymphocytes and NK cells subtypes were counted by flow cytometry before and 3, 6 and 12 months after RTX administration. Patients were evaluated for disease activity with DAS28-CRP and EULAR response criteria at each visit. Results RTX significantly increased from baseline values CD56+3- cells (28 %, 19 % and 25 %; p<0.001, p=0.009 and p=0.004 respectively for month 3, 6 and 12) and CD56dimCD16+ cells (41%, 24% and 36%; p<0.001, p=0.001 and p<0.001 respectively for month 3, 6 and 12). CD56bri16- cells were unaffected by RTX treatment. The increase in both CD56+3- and CD56dimCD16+ cells was significantly greater in patients who were re-treated with another course of RTX at month 6 (p=0.046 and p=0.010 respectively). An inverse correlation between disease activity score and increase in NK cells was demonstrated. No significant changes were observed in CD3+, CD4+ and CD8+ cells during the whole observation period. Conclusion In RA patients, RTX treatment is associated with significant and persistent increase in CD56+3- and CD56dimCD16+ NK cells. A correlation with disease activity is probable, although the association with clinical response remains to be proved
