From Psoriasis to Psoriatic Arthritis: Decoding the Impact of Treatment Modalities on the Prevention of Psoriatic Arthritis.

INTRODUCTION: Biologic therapies are licensed for both psoriasis (PsO) and psoriatic arthritis (PsA) with some electronic medical record data suggest that IL (Interleukin)-23 blockers might be more protective in PsA prevention than TNF blockers; however, the findings have been inconsistent. Higher Psoriasis Area and Severity Index (PASI) scores have also been linked to an increased PsA risk. To clarify these unresolved issues we investigated biologic agents, methotrexate, phototherapy, and topical therapy for PsA prevention in patients with psoriasis. METHODS: This retrospective cohort study analyzed data from 58,671 patients with psoriasis from the Israeli Meuhedet Health Services Organization database was evaluated for incident PsA. Patients were categorized on the basis of treatment: group 1, topical therapy; group 2, phototherapy; group 3, conventional disease-modifying antirheumatic drugs (cDMARDs; methotrexate); group 4, biologic DMARDs which was also stratified according to biologic class. RESULTS: The PsA incidence rate was lower in the biologic agents' group versus the methotrexate group (HR 0.46 [95% CI 0.35-0.62]). The incidence rates per 100 person-years varied across biologic treatment groups, with the anti­IL­12/23 or anti­IL­23p19 group at 4.57, the anti-IL-17 group at 4.35, and the TNF inhibitor group at 2.55. No differences were found between various biological agents in terms of preventing PsA. The phototherapy group exhibited a higher PsA development rate than the topical therapy group (HR 1.85 [95% CI 1.65-2.07]). CONCLUSION: Biological agents are more effective than methotrexate in reducing incident PsA in patients with psoriasis. This lower rate of PsA on topical therapy compared to phototherapy supports the importance of psoriasis severity as a risk factor.

Increased Risk for Pulmonary Embolism among Patients with Ankylosing Spondylitis-Results from a Large Database Analysis.

Background: Axial spondyloarthropathy(AS) is a chronic inflammatory disease primarily affecting the axial skeleton, often characterized by sacroiliitis. While pulmonary embolism (PE), a potentially lethal condition, has been linked to several autoimmune diseases, limited data exist regarding PE risk among patients with AS. Methods: This retrospective cohort study utilized the Clalit Healthcare Services (CHS) database, including 5825 patients with AS and 28,356 matched controls. Follow-up began at the date of first AS diagnosis for patients and at the matched patient's diagnosis date for controls and continued until PE diagnosis, death, or study end date. Results: Prevalence of PE before AS diagnosis in patients compared to controls was 0.4% vs. 0.2% (p < 0.01). The incidence rate of PE was 11.6 per 10,000 person-years for patients with AS and 6.8 per 10,000 person-years for controls. The adjusted hazard ratio (HR) for PE in patients with AS was 1.70 (p < 0.001). Subgroup analysis demonstrated excess risk for PE in patients with AS regardless of gender and age, with variations among AS treatment categories. Discussion: Our findings highlight a significant association between AS and PE, indicating an increased risk in patients with AS independent of age and sex and suggests a subclinical level of inflammation. Preliminary results suggest a protective role of immunosuppressing drugs. Further research into the impact of treatment strategies should be conducted and could inform clinical management and reduce the life-threatening risk of PE in Patients with AS.

Exploring the Link Between Ankylosing Spondylitis and Inflammatory Bowel Disease: A Retrospective Cohort Study.

BACKGROUND: Ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) are chronic conditions with overlapping pathogenic mechanisms. The genetic predisposition and inflammatory pathways common to both diseases suggest a syndemic relationship. While some evidence points to a connection between the two conditions, other reports do not support this link. OBJECTIVES: To investigate the association between AS and the subsequent incidence of IBD. To identify potential risk factors and effect modifiers that contribute to this relationship. METHODS: Utilizing the Chronic Disease Registry of Clalit Health Services, we conducted a retrospective cohort study of individuals diagnosed with AS between January 2002 and December 2018. We compared these patients with age- and sex-matched controls, excluding those with a prior diagnosis of IBD. Statistical analyses included chi-square and t-tests for demographic comparisons, and Cox proportional hazards models for evaluating the risk of IBD development, with adjustments for various co-morbidities and demographic factors. RESULTS: The study included 5825 AS patients and 28,356 controls. AS patients demonstrated a significantly higher incidence of IBD with hazard ratios of 6.09 for Crohn's disease and 2.31 for ulcerative colitis, after multivariate adjustment. The overall incidence of IBD in the AS cohort was significantly higher compared to controls. CONCLUSIONS: AS patients exhibit a markedly increased risk of developing IBD. These findings advocate for heightened clinical vigilance for IBD symptoms in AS patients and suggest the need for a multidisciplinary approach to patient care. Further research into the shared pathogenic pathways is needed to develop personalized treatment strategies and improve patient management.

Arthroplasty Rates and Risk in Familial Mediterranean Fever Patients: A large Population-Based Study.

BACKGROUND: Familial Mediterranean Fever (FMF) is a genetic disorder characterized by recurrent episodes of fever and inflammation in various organs, including the joints. Traditionally, the arthritis of FMF has been considered relatively harmless. However, anecdotal evidence has suggested that it may contribute to long-term joint damage, which may necessitate surgical joint replacement. This study aimed to investigate the rates of arthroplasty among FMF patients and compare it to the general population. METHODS: The study used the electronic database of the largest healthcare organization in Israel to identify 9,769 FMF patients diagnosed between 2000 and 2016. A similar number of age-, gender-, and residency-matched controls were also identified. The rates of arthroplasty were compared between the two groups. A logistic regression model predicting the need for arthroplasty within the FMF group was formed to identify potential risk factors. RESULTS: Of the 9,769 FMF patients, 114 (1.2%) underwent arthroplasty, compared with 64 (0.7%) of the control group [unadjusted odds ratio (OR)=1.79, 95% confidence interval (CI) 1.32-2.43; partially adjusted OR = 1.97, 95% CI 1.40-2.77; fully adjusted OR = 1.92, 95% CI 1.35-2.72]. Within the FMF cohort, those of North African origin had a significantly higher risk of arthroplasty (OR = 6.89, 95% CI 5.09-9.33; p< 0.001). CONCLUSION: FMF patients can experience long-term joint damage that may require arthroplasty. Although this complication is relatively uncommon in FMF patients, it occurs almost twice as frequently as compared with the general population. FMF patients of North African origin are at an even higher risk.

Biologic Treatment Modification Efficacy in Concurrent Inflammatory Bowel Disease and Ankylosing Spondylitis: A Retrospective Cohort Study at a Single Tertiary Center.

BACKGROUND: The link between ankylosing spondylitis (AS) and inflammatory bowel disease (IBD) is well-established, with concurrent prevalence estimates ranging from 5-10%. However, there are still significant gaps in our understanding, and a comprehensive treatment guideline for these co-diagnosed patients has yet to be established. Our objective was to explore patterns of treatment alterations following the diagnosis of AS in patients previously diagnosed with IBD, and vice versa. Additionally, we sought to determine how these modifications influence clinical outcomes in both conditions. METHODS: This retrospective data-based cohort study included patients with coexisting IBD and AS that were diagnosed between the years 2009-2022 and were followed by the gastroenterology and the rheumatology units of the Sheba Medical Center, Israel. The data were extracted from the electronic health record and included demographic information, medication history, treatment modification at the time of second diagnosis, and the characteristics and activity of both IBD and AS at the index time and at the 3-month mark. RESULTS: The study included a total of 68 patients, with a male predominance (40 patients, 59%). The median age was 43 years (IQR 31-55) and 78% had Crohn's disease (CD). The median duration between the diagnosis of the first disease to the second one was 4 years (IQR 1-9.5). A significant proportion of patients (85%) underwent treatment modification at their second diagnosis. Out of the total cohort, 28% initiated biological therapy, 17.6% switched their biologic regimen, and 16.2% discontinued NSAIDS. Patients who underwent biologic modifications at time of the second diagnosis (the initiation/switch/augmentation of a concurrent regimen) experienced significantly higher rates of clinical improvement in either IBD or AS at the 90-day follow-up compared to patients who did not (68% vs. 32%, p = 0.004), and biologic modification was found to be an independent predictor for clinical improvement (OR 3.69, CI 1.08-12.58, p = 0.037). CONCLUSIONS: Our findings suggest that biologic therapy modification at the time of the second diagnosis was associated with a higher rate of improvement in AS/IBD at the 90-day follow-up.

Increased risk for stroke in patients with familial Mediterranean fever: results from a large population-based study.

OBJECTIVE: The association between chronic inflammatory conditions and cardiovascular disease is well established. Considering FMF, few studies exist investigating the risk of ischaemic heart disease, and none address the risk of stroke. We aimed to evaluate the incidence and risk for stroke in FMF patients compared with the general population. METHODS: A retrospective cohort study using the electronic database of Clalit Health Services (CHS), the largest health organization in Israel. All FMF patients diagnosed between 2000 and 2016 were included and matched with control according to age, gender and place of residence. Follow-up continued until the first diagnosis of stroke or death. The incidence of stroke was compared between the groups using univariate and multivariate models adjusting for cardiovascular risk-factors. RESULTS: A total of 9769 FMF patients and a similar number of controls were followed up for a median period of 12.5 years. The mean age at the beginning of the follow-up was 25.7 years. In total, 208 FMF patients were diagnosed with stroke compared with 148 controls, resulting in an incidence rate (per 10 000 persons-years) of 19.8 (95% CI 17.2, 22.7) and 13.9 (95% CI 11.8, 16.4), respectively, and a crude HR of 1.42 (95% CI 1.15-1.76; P < 0.001). In a multivariate analysis, FMF patients who developed amyloidosis with related or non-related renal failure demonstrated significant stroke risk (HR = 2.16; 95% CI 1.38, 3.38; P < 0.001), as well as for those who did not develop these complications (HR = 1.32; 95% CI 1.04, 1.67; P < 0.05). CONCLUSION: FMF patients are at increased risk for stroke regardless of known complications.

Association of fibromyalgia with cancerous and non-cancerous gastrointestinal comorbidities: a cross-sectional study.

OBJECTIVES: Several studies have shown a higher prevalence of irritable bowel syndrome (IBS) among patients with fibromyalgia yet, data regarding association between fibromyalgia and other gastrointestinal disorders have been relatively overlooked. Our aim was to investigate the association between fibromyalgia and gastrointestinal disorders including both benign and malignant conditions. METHODS: We conducted a retrospective cross-sectional study based on the comprehensive electronic database of the largest health maintenance organisation in Israel. All subjects with a diagnosis of fibromyalgia in their medical records and age- and sex-matched controls were included in the study. We investigated the association of fibromyalgia with benign gastrointestinal disorders including IBS, gastroesophageal reflux disease (GERD), peptic ulcer disease (PUD), celiac disease, Crohn's disease, ulcerative colitis, and with gastrointestinal malignancies including colorectal, pancreatic, stomach, liver, and bile duct cancers. RESULTS: The study enrolled 18,598 patients with fibromyalgia and 36,985 controls. The mean age was 56.5 years (standard deviation=14) with a female predominance (91%). Fibromyalgia was significantly associated with IBS (OR 4.61, 95% CI 4.09-5.2, p<0.001), GERD (OR 2.62, 95% CI 2.5-2.75, p<0.001), PUD (OR 2.13, 95% CI 1.98-2.3, p<0.001), celiac disease (OR 2.08, 95% CI 1.63-2.65, p<0.001), Crohn's disease (OR 1.85, 95% CI 1.408-2.32, p<0.001) and ulcerative colitis (OR 1.81, 95%CI 1.4-2.33, p<0.001). Nonetheless, no significant differences were found regarding the prevalence of gastrointestinal malignancies between the fibromyalgia patients and controls. CONCLUSIONS: Our findings suggest that FM is positively associated with various benign but not malignant GI disorders.

The possible onset of fibromyalgia following acute COVID-19 infection.

INTRODUCTION: The exact pathogenesis of fibromyalgia (FM) syndrome is unclear. However, various infectious have been implicated with the development of FM after their acute phase. We aimed to investigate the incidence of FM syndrome among convalesced individuals following hospitalization for Acute Coronavirus Disease-2019 (COVID-19). METHODS: We performed a cross-sectional study on patients who were discharged after COVID-19 hospitalization from the Sheba Medical Center, Israel, between July 2020 to November 2020. A phone interview was performed consisting of the following questionnaires: the Fibromyalgia Survey Diagnostic Criteria Questionnaire, Sense of Coherence Questionnaire to evaluate resilience, and the Subjective Traumatic Outlook Questionnaire to assess the associated psychological aspects of the trauma. The incidence of post-COVID FM was calculated and regression models were performed to identify predictors. RESULTS: The study population consisted of 198 eligible patients who completed the phone interview. The median age was 64 (52-72) and 37% were women. The median follow-up was 5.2 months (IQR 4.4-5.8). The incidence of FM was 15% (30 patients) and 87% (172 patients) had at least one FM-related symptom. Female gender was significantly associated with post-COVID FM (OR 3.65, p = 0.002). In addition, high median Subjective Traumatic Outlook scores and low median Sense of Coherence scores were both significantly associated with post-COVID FM (OR 1.19, p<0.001 and OR 0.92, p<0.001, respectively). CONCLUSIONS: FM is highly prevalent among COVID-19 convalescent patients. Our finding suggests that a significant subjective traumatic experience and a low resilience are highly associated with post-COVID FM.

Association Between Behçet's Disease and Depression.

BACKGROUND: Behçet's disease (BD) is a chronic vasculitic multi-systemic disease of unknown etiology. BD is characterized by recurrent attacks of oral aphthae, genital ulcers, and uveitis. BD is a multisystemic disorder and as such it may provoke various psychiatric manifestations, including depression. OBJECTIVES: To evaluate the association between BD and depression, adjusting for established risk factors for depression. METHODS: We executed a cross-sectional study based on the Clalit Health Services database, the largest healthcare organization in Israel, serving over 4.4 million members. For this study 873 BD patients were detected and matched with 4369 controls by age and sex. RESULTS: The rate of depression was higher among the BD patients compared with the control group (9.39% vs 5.49%, respectively, odds ratio [OR] 1.79, 95% confidence interval [95%CI] 1.37-2.31, P < 0.001). An association between BD and depression was also observed on multivariable analysis (OR 1.83, 95%CI 1.39-2.39, P < 0.001). When stratifying the data, according to established risk factors, the association between BD and depression was prominent in the youngest age group (18-39 years of age), low and high socioeconomical status, and non-smokers. CONCLUSIONS: Establishing the association between BD and depression should influence the attitude and the treatment of BD patients, as this relationship requires a more holistic approach and a multidisciplinary treatment regimen for all patient needs.

Increased risk of venous thromboembolism among patients with familial Mediterranean fever.

INTRODUCTION: Familial Mediterranean Fever (FMF) is an auto inflammatory disease characterized by acute febrile attacks, serositis, arthritis and skin rash. Previous studies have identified an association between venous thromboembolism (VTE) and various inflammatory and autoimmune disorders, driven in large part by inflammatory processes. Despite these established associations, there remains a paucity of data linking FMF to VTE. The purpose of this study is to evaluate the association between VTE in patients with FMF compared to matched controls. METHOD: A population based cross-sectional study was performed utilizing the electronic medical database of Israel's largest healthcare provider, Clalit Health Services. Using this database, we looked at the prevalence of VTE in a cohort of FMF patients compared to matched controls. Univariate logistic regression was used to evaluate the association between FMF and VTE. Multivariate analysis was conducted to adjust for age, sex, socioeconomic status and comorbidities associated with VTE. RESULTS: A total of 6534 FMF patients were identified and matched with an equal number of controls. In univariate analysis the cumulative percent of VTE was higher in FMF patient compared to matched controls (FMF 3%, Control 2%). In a multivariate logistic regression analysis FMF was found to be independently associated with VTE (HR 1.96, P < 0.001). CONCLUSION: FMF is associated with increased risk of VTE. This association is likely the result of a chronic and persisting inflammatory state. Physicians should be aware of this sequela and care must be undertaken to control unbalanced disease.

Three's Company: Coexistence of Silicosis, Scleroderma, and Sjogren Syndrome in a Single Patient.

We describe a patient who presented with silicosis, scleroderma, and Sjogren syndrome all at the same time. The diagnoses in this case are all associated with continuous exposure to crystalline silica at the patient's workplace. The following report discusses this unique presentation.

The frequency of sacroiliitis on MRI in subjects over 55 years of age.

OBJECTIVE: To evaluate the frequency of sacroiliitis in older subjects. MATERIALS AND METHODS: Consecutive MRI examinations of the sacroiliac joints (SIJs) performed for suspected sacroiliitis (2005-2019) in patients ≥ 18 years were retrospectively evaluated for the presence of active/structural lesions and were categorized for the presence/absence of sacroiliitis. Clinical and imaging parameters were compared between subjects with sacroiliitis according to age groups < 40 years, 40-55, and > 55 years. Clinical parameters including inflammatory back pain (IBP) and other spondyloarthritis (SpA) features were retrieved from the medical records. RESULTS: A total of 431 patients with SIJs MRI were evaluated: median age, 44 [IQR 35-54]; female:male 267(62%):164(38%). Sacroiliitis was diagnosed in 89 (20.6%) subjects-median age, 41 years [IQR 32-54], 52% females- and was equally prevalent among the different age groups: > 40 years old, 23.6%; 40-55, 20%; and > 55 years old, 17%, p = 0.43, with active/structural lesions equally dispersed. Older patients (> 55) started suffering from back pain at an older age and had a longer delay in diagnosis. Gender distribution, the presence of IBP, and other SpA features were no different in patients < 45 and > 55 years of age. CONCLUSIONS: The frequency of sacroiliitis on SIJs-MRI in subjects > 55 years is similar to its frequency in younger subjects and is associated with the same type and magnitude of active and structural MRI lesions. Clinical parameters such as IBP and additional SpA features are similarly prevalent in older and younger subjects suggesting they suffer from the same disease and differing only in age of presentation.

Secukinumab real world drug retention compared to TNF-alpha inhibitors in psoriatic arthritis.

OBJECTIVES: To prospectively study real-world efficacy and safety of secukinumab in psoriatic arthritis (PsA) patients from the Israeli registry of inflammatory diseases. METHODS: PsA patients fulfilling the CASPAR criteria were included in the analysis from 2010 to 2019. The primary endpoint was secukinumab drug retention compared to other TNF-α inhibitors (TNFi). Bivariate and multivariate analyses were made by Cox regression analysis. Drug retention according to treatment line was examined with Kaplan-Meier curves. RESULTS: Included were 404 PsA patients who had 709 treatment courses during the study period. Ninety patients had been treated with secukinumab (22%). The secukinumab-treated patients were significantly older and their disease duration was longer. Secukinumab was less likely to be the first line of treatment compared to TNFi. Secukinumab had a drug retention comparable to TNFi, and a better drug retention than TNFi among biologic-experienced patients. Neither methotrexate combination nor body mass index affected the inefficacy event rate. Secukinumab had a similar rate of adverse events as TNFi. CONCLUSIONS: This multicentre real-world study demonstrated that secukinumab had a drug retention comparable to TNFi. Secukinumab had a better drug retention than TNFi among biologic-experienced patients. IL-17 inhibition is an effective mechanism of action to treat PsA in real life.

Bisphosphonates Related Ocular Side Effects: A Case Series and Review of Literature.

OBJECTIVE: To describe the clinical features of patients with bisphosphonate related ocular side effects (BROSE). METHODS: The medical records of all patients with BROSE between January 2009 and December 2019 were reviewed. RESULTS: Nine cases with BROSE were identified. All subjects were female. Median age at diagnosis was of 69 years. The leading indication for bisphosphonate treatment was osteoporosis (n=7), Paget's disease of bone (n=1) and breast cancer (n=1). Six (66.67%) patients presented with uveitis, one (11%) episcleritis and two (22%) with orbital inflammation. Five events (55.5%) occurred within 10 days of initiating the bisphosphonate and the rest (44.44%) developed within 2 weeks to 3 years later. Four (44.44%) patients had concurrent thyroid disease. An association was found between underlying thyroid disease or autoimmunity. CONCLUSION: BROSE is an uncommon complication of bisphosphonate therapy occurring more frequently in patients with an autoimmune predisposition.

Autonomic Nervous System Indices in Patients with Systemic Sclerosis without Overt Cardiac Disease.

BACKGROUND: Systemic sclerosis (SSc) is a connective tissue disease that may affect the heart and the autonomic nervous system (ANS). There is little knowledge regarding the degree of ANS involvement in SSc patients with unknown cardiac disease. OBJECTIVES: To evaluate cardiac and pupillary autonomic functions in patients before cardiac involvement has emerged. METHODS: The study comprised 19 patients with SSc and 29 healthy controls. Heart rate variability (HRV) analysis for time and frequency domains, as well as deep breathing test and Ewing maneuvers, were performed in all patients. Automated pupillometry for the evaluation of pupillary diameter and pupillary light reflex was completed in 8 SSc patients and 21 controls. RESULTS: Both groups had similar characteristics, except for medications that were more commonly or solely prescribed for SSc patients. Compared with control subjects, the SSc patients had significantly lower HRV parameters of NN50 (15.8 ± 24.4 vs. 33.9 ± 33.1, P = 0.03), pNN50 (4.9 ± 7.4% vs.10.8 ± 10.8%, P = 0.03), and triangular index (11.7 ± 3.4 vs. 15.7 ± 5.8, P = 0.02). Abnormal adaptive responses in heart rate changes were recorded during deep breathing tests and Ewing maneuvers. There was no significant difference in any of the pupillometric indices or other HRV parameters within groups. CONCLUSIONS: SSc patients may manifest cardiac autonomic dysfunction, while their autonomic pupillary function is seemingly spared. The role of certain medications, the significance of differential organ involvement, as well as the prognostic value of our findings should be evaluated in future studies.

Automated processing of thermal imaging to detect COVID-19.

Rapid and sensitive screening tools for SARS-CoV-2 infection are essential to limit the spread of COVID-19 and to properly allocate national resources. Here, we developed a new point-of-care, non-contact thermal imaging tool to detect COVID-19, based on advanced image processing algorithms. We captured thermal images of the backs of individuals with and without COVID-19 using a portable thermal camera that connects directly to smartphones. Our novel image processing algorithms automatically extracted multiple texture and shape features of the thermal images and achieved an area under the curve (AUC) of 0.85 in COVID-19 detection with up to 92% sensitivity. Thermal imaging scores were inversely correlated with clinical variables associated with COVID-19 disease progression. In summary, we show, for the first time, that a hand-held thermal imaging device can be used to detect COVID-19. Non-invasive thermal imaging could be used to screen for COVID-19 in out-of-hospital settings, especially in low-income regions with limited imaging resources.

Systematic Review and Meta-Analysis of Tocilizumab Therapy versus Standard of Care in over 15,000 COVID-19 Pneumonia Patients during the First Eight Months of the Pandemic.

BACKGROUND: Tocilizumab is an anti-IL-6 therapy widely adopted in the management of the so-called "cytokine storm" related to SARS-CoV-2 virus infection, but its effectiveness, use in relation to concomitant corticosteroid therapy and safety were unproven despite widespread use in numerous studies, mostly open label at the start of the pandemic. METHODS: We performed a systematic review and meta-analysis of case-control studies utilising tocilizumab in COVID-19 on different databases (PubMed/MEDLINE/Scopus) and preprint servers (medRxiv and SSRN) from inception until 20 July 2020 (PROSPERO CRD42020195690). Subgroup analyses and meta-regressions were performed. The impact of tocilizumab and concomitant corticosteroid therapy or tocilizumab alone versus standard of care (SOC) on the death rate, need for mechanical ventilation, ICU admission and bacterial infections were assessed. RESULTS: Thirty-nine studies with 15,531 patients (3657 cases versus 11,874 controls) were identified. Unadjusted estimates (n = 28) failed to demonstrate a protective effect of tocilizumab on survival (OR 0.74 ([95%CI 0.55-1.01], p = 0.057), mechanical ventilation prevention (OR 2.21 [95%CI 0.53-9.23], p = 0.277) or prevention of ICU admission (OR 3.79 [95%CI 0.38-37.34], p = 0.254). Considering studies with adjusted, estimated, tocilizumab use was associated with mortality rate reduction (HR 0.50 ([95%CI 0.38-0.64], p < 0.001) and prevention of ICU admission (OR 0.16 ([95%CI 0.06-0.43], p < 0.001). Tocilizumab with concomitant steroid use versus SOC was protective with an OR of 0.49 ([95%CI 0.36-0.65], p < 0.05) as was tocilizumab alone versus SOC with an OR of 0.59 ([95%CI 0.34-1.00], p < 0.001). Risk of infection increased (2.36 [95%CI 1.001-5.54], p = 0.050; based on unadjusted estimates). CONCLUSION: Despite the heterogeneity of included studies and large number of preprint articles, our findings from the first eight of the pandemic in over 15,000 COVID-19 cases suggested an incremental efficacy of tocilizumab in severe COVID-19 that were confirmed by subsequent meta-analyses of large randomized trials of tocilizumab. This suggests that analysis of case-control studies and pre-print server data in the early stages of a pandemic appeared robust for supporting incremental benefits and lack of major therapeutic toxicity of tocilizumab for severe COVID-19.

Utilisation of healthcare services and drug consumption in fibromyalgia: A cross-sectional analysis of the Clalit Health Service database.

AIM: To investigate the health care utilisation and drug consumption of patients with fibromyalgia (FM). MATERIALS AND METHODS: This is a cross-sectional study using the Clalit Health Care database. Clalit is the largest HMO in Israel, serving more than 4.4 million enrollees. We identified FM patients and age and sex-matched controls. Indicators of healthcare utilisation and drug consumption were extracted and analysed for both groups. RESULTS: The study included 14 296 FM patients and 71 324 controls. The mean age was 56 years, with a women predominance of 92%. The mean number of visits across of all healthcare services (hospitalisations, emergency department visit, general practitioner clinic visits, rheumatology clinic visits, and pain clinic visits) and the mean difference (MD) were significantly higher for FM patients compared with controls (MD 0.66, P < .001; MD 0.23, P < .001; MD 7.49, P < .001; MD 0.31, P < .001; MD 0.13, P < .001), respectively. Drug use was significantly and consistently higher among FM patients compared with controls; NSAIDs (non-steroidal anti-inflammatory drugs) OR 2.56, P < .001; Opioids OR 4.23, P < .001; TCA (tricyclic antidepressants) OR 8.21, P < .001; Gabapentinoids OR 6.31, P < .001; SSRI (selective serotonin reuptake inhibitors) OR 2.07, P < .001; SNRI (serotonin-norepinephrine reuptake inhibitor) OR 7.43, P < .001. CONCLUSION: Healthcare utilisation and drug use are substantially higher among patients with FM compared with controls.

Tumor-like Lesions in Patients with Granulomatosis with Polyangiitis: A Case Series.

BACKGROUND: Granulomatosis with polyangiitis (GPA) is a rare small vessel vasculitis. It usually involves the respiratory tract and kidney. Rarely, tumor-resembling inflammatory changes ensue. OBJECTIVES: To report three unique cases of GPA presenting with tumor-like lesions in various organs. METHODS: We presented three cases of GPA. Case 1 presented with typical upper respiratory symptoms of GPA and a mediastinal mass. Case 2 presented with low back pain, a large retroperitoneal mass, and nodular skin lesions. Case 3 presented with epigastric pain and a paravertebral inflammatory mass. RESULTS: The patients were treated successfully with rituximab. CONCLUSIONS: Clinicians should be aware of this presentation of granulomatosis with polyangiitis, which is known as Tumefaction Wegener's granulomatosis.

Familial Mediterranean fever and asthma.

OBJECTIVE: To assess the association between FMF and asthma. METHODS: This study was designed as a cross-sectional study. All patients diagnosed with FMF between 1 January 2000 and 31 December 2016 who were prescribed colchicine were included in the study. Controls were matched by sex, date of birth, residential socioeconomic status and country of birth. Logistic regression models were used to determine the odds ratio for asthma in FMF patients and controls. RESULTS: A total of 7098 FMF patients who were prescribed colchicine were identified. Of them, 3547 (50%) were females, 3632 (51%) were of low residential socioeconomic status and 6160 (87%) were born in Israel. Their median age at the end of follow-up was 37 years (23-54). In an unadjusted logistic regression, FMF was associated with asthma [odds ratio (OR)=1.33, 95% CI: 1.17, 1.51; P <0.001]. The association persisted after adjusting for sex, socioeconomic status and country of birth (OR=1.33, 95% CI: 1.18, 1.52; P <0.001). CONCLUSION: FMF is positively associated with asthma. Further research is required to validate our results and explore possible explanations of this association. These findings cast doubt on previous studies implying FMF to be a protective factor from asthma.
