Introduction: There are several treatment controversies that have emerged in spondyloarthritis and psoriatic arthritis. These are related to the nature of the conditions as well as to the use of medications. Areas covered: This review, which included a search of PubMed database as well as the references within the articles provides an overview of the nature of spondyloarthritis, controversy over the inclusion of psoriatic arthritis (PsA) as a peripheral spondyloarthritis, and a summary of current treatments for both PsA and axial spondyloarthritis (axSpA), with special emphasis on targeted therapy. The review highlights the differences in response to certain medications, particularly biologic therapy and summarizes the randomized controlled trials in psoriatic arthritis and axial spondyloarthritis providing data about the responses in table format. Expert opinion: There is a need for better outcome measures in axSpA. Currently, the measures are subjective. Imaging may be more appropriate but there is a need for research into the reliability and responsiveness of imaging techniques. In PsA, there may also be better response measures and research into the reliability and responsiveness of available measures is underway. There is also a need for novel therapies as well as biomarkers for response in both diseases. [ABSTRACT FROM AUTHOR]

Despite the increasing recognition of cardiac involvement in systemic sarcoidosis, the diagnosis of cardiac sarcoidosis (CS) remains challenging. Our aim is to present a comprehensive, retrospective case series of CS patients, focusing on the current diagnostic guidelines and management of this life-threatening condition. In our case series, patient data were collected retrospectively, including hospital admission records and rheumatology and cardiology clinic visit notes, detailing demographic, clinical, laboratory, pathology, and imaging studies, as well as cardiac devices and prescribed medications. Cases were divided into definite and probable CS based on the 2014 Heart Rhythm Society guidelines as well as presumed CS based on imaging criteria and clinical findings. Overall, 19 CS patients were included, 17 of whom were diagnosed with probable or presumed CS based on cardiac magnetic resonance imaging (CMR) and/or cardiac positron emission tomography using 18F-Fluorodeoxyglucose (PET-FDG) without supporting endomyocardial biopsy (EMB). The majority of CS patients were male (53%), with a mean age of 52.9 ± 11.8, with CS being the initial manifestation of sarcoidosis in 63% of cases. Most patients presented with high-grade AVB (63%), followed by heart failure (42%) and ventricular tachyarrhythmia (VT) (26%). This case series highlights the significance of utilizing updated diagnostic criteria relying on CMR and PET-FDG given that cardiac involvement can be the initial manifestation of systemic sarcoidosis, requiring prompt diagnosis and treatment to prevent morbidity and mortality.

Objective: We aimed to characterize the course of COVID-19 in autoimmune inflammatory rheumatic disease (AIIRD) patients in Israel, taking into consideration several remarkable aspects, including the outcomes of the different outbreaks, the effect of vaccination campaigns, and AIIRD activity post-recovery. Methods: We established a national registry of AIIRD patients diagnosed with COVID-19, including demographic data, AIIRD diagnosis, duration and systemic involvement, comorbidities, date of COVID-19 diagnosis, clinical course, and dates of vaccinations. COVID-19 was diagnosed by a positive SARS-CoV-2 polymerase chain reaction. Results: Israel experienced 4 outbreaks of COVID-19 until 30.11.2021. The first three outbreaks (1.3.2020 - 30.4.2021) comprised 298 AIIRD patients. 64.9% had a mild disease and 24.2% had a severe course; 161 (53.3%) patients were hospitalized, 27 (8.9%) died. The 4th outbreak (delta variant), starting 6 months after the beginning of the vaccination campaign comprised 110 patients. Despite similar demographic and clinical characteristics, a smaller proportion of AIIRD patients had negative outcomes as compared to the first 3 outbreaks, with regards to severity (16 patients, 14.5%), hospitalization (29 patients, 26.4%) and death (7 patients, 6.4%). COVID-19 did not seem to influence the AIIRD activity 1-3 months post-recovery. Conclusions: COVID-19 is more severe and has an increased mortality in active AIIRD patients with systemic involvement, older age and comorbidities. Vaccination with 3 doses of the mRNA vaccine against SARS-CoV-2 protected from severe COVID-19, hospitalization and death during the 4th outbreak. The pattern of spread of COVID-19 in AIIRD patients was similar to the general population. [ABSTRACT FROM AUTHOR]

The association between infectious diseases and autoimmunity has long been reported. Specifically, during the coronavirus disease 2019 (COVID-19) pandemic, this relation was further emphasized. The interplay between the two disease processes remains interesting, yet incompletely defined. Herein, we report a case series of six patients presenting with autoimmune phenomena first developed or exacerbated following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. We describe the disease course and discuss the possible mechanisms underlying the association between autoimmunity and COVID-19. [ABSTRACT FROM AUTHOR]

We report the case of a 65 year old female patient, presenting with a combination of bilateral hearing loss, otalgia, and hyperacusis. Pure tone audiometry revealed mixed bilateral hearing loss. Conventional cranial imaging tests failed to show a significant brain pathology, but fat‐suppressed T1‐weighted gadolinium‐enhanced magnetic resonance imaging scan displayed a diffuse infiltrative skull base process, extending from the nasopharynx to the jugular fossa, and encasing the internal carotid artery. The latter findings, besides elevated inflammatory markers and a positive perinuclear anti‐neutrophil cytoplasmic antibody (p‐ANCA) led to the diagnosis of ANCA‐associated vasculitis. Additional disease manifestations sequentially appeared, including a right peripheral nerve palsy, aortitis, hepatitis, peripheral neuropathy, and uveitis. Therapy with corticosteroids, azathioprine, and then cyclophosphamide brought no evident benefit, but rituximab led to impressive clinical and radiologic improvement. [ABSTRACT FROM AUTHOR]

Treatment with rituximab (RTX) blunts SARS-CoV-2 vaccination-induced humoral response. We sought to identify predictors of a positive immunogenic response to the BNT162b2 mRNA vaccine in patients with autoimmune inflammatory rheumatic diseases (AIIRD) treated with RTX (AIIRD-RTX). We analyzed 108 AIIRD-RTX patients and 122 immunocompetent controls vaccinated with BNT162b2 mRNA participating in a multicenter vaccination study. Immunogenicity was defined by positive anti-SARS-CoV-2 S1/S2 IgG. We used a stepwise backward multiple logistic regression to identify predicting factors for a positive immunogenic response to vaccination and develop a predicting calculator, further validated in an independent cohort of AIIRD-RTX BNT162b2 mRNA vaccinated patients (n = 48). AIIRD-RTX patients who mounted a seropositive immunogenic response significantly differed from patients who did not by a lower number of RTX courses (median (range) 3 (1–10) vs. 5 (1–15), p = 0.007; lower cumulative RTX dose (mean ± SD) 6943.11 ± 5975.74 vs. 9780.95 ± 7240.12 mg, p = 0.033; higher IgG level prior to last RTX course (mean ± SD), 1189.78 ± 576.28 vs. 884.33 ± 302.31 mg/dL, p = 0.002), and extended interval between RTX treatment and vaccination, 469.82 ± 570.39 vs. 162.08 ± 160.12 days, p = 0.0009, respectively. Patients with ANCA-associated vasculitis and inflammatory myositis had a low likelihood of a seropositive immunogenic response compared to patients with rheumatoid arthritis, odds ratio (OR) 0.209, 95% confidence interval (CI) 0.046–0.96, p = 0.044 and OR 0.189, 95% CI 0.036–0.987, p = 0.048, respectively. Based on these findings, we constructed a calculator predicting the probability of a seropositive immunogenic response following BNT162b2 mRNA vaccination which performed with 90.5% sensitivity, 59.3% specificity, and 63.3% positive and 88.9% negative predictive values. In summary, the predicting calculator could guide clinicians for optimal timing of BNT162b2 mRNA vaccination in AIIRD-RTX patients. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 35-year-old female patient with exertion and responding poorly to treatment with simple analgesics.

Antiphospholipid syndrome and cold agglutinin-mediated autoimmune hemolytic anemia are 2 distinct immune-mediated hematologic disorders. While no clear association exists between these 2 entities, complement activation is known to occur in both of them. Herein, we report a unique case of cold agglutinin hemolytic anemia in a patient with a known primary antiphospholipid syndrome. [ABSTRACT FROM AUTHOR]

Objectives To evaluate the incidence of hospitalization for coronavirus disease 2019 (COVID-19) in patients with FMF, as compared with the general population, and to compare the disease course between FMF inpatients, and age-, sex-, ethnicity- and comorbidity-matched non-FMF COVID-19 inpatients. Methods We used electronic medical records to obtain data about the total number of the insured population and the number of FMF patients in the two largest health management organizations in Jerusalem, Clalit and Meuhedet. The total number of COVID-19 inpatients at the Hadassah Medical Center, including those with FMF, for the period between 1 February 2020 and 10March 2021, was retrieved from the electronic medical records of Hadassah. COVID-19 course was compared between the FMF inpatient group and age-, sex-, ethnicity- and comorbidity-matched non-FMF COVID-19 inpatients. Each FMF inpatient was matched with two non-FMF controls. Results We found no statistically significant difference in the odds of hospitalization for COVID-19 between FMF patients and the non-FMF population (0.46% vs 0.41%, P = 0.73). Furthermore, we found similar disease severity and therapeutic approach in FMF COVID-19 inpatients and matched non-FMF COVID-19 inpatients. Conclusions Neither FMF nor baseline colchicine therapy, appear to affect the incidence of hospitalization for COVID-19 or the disease course, in terms of severity and therapeutic approach.

In our previously published article, The Osteosclerosis Challenge: Toothpaste Unveiling Secrets ([1]), we reported the case of a tricenarian female patient with severe osteosclerosis, secondary to prolonged intentional fluoride consumption through toothpaste and mouthwash. Upon analysis, a very high fluoride content was found. gl Laboratory analysis was performed on the stones, revealing an extremely high fluoride concentration, approaching 22.6 parts per million. Chronic fluoride ingestion can lead to skeletal fluorosis, with the unfortunate effects on bone lasting for several years, and sometimes mimicking rheumatic diseases. [Extracted from the article]

Psoriatic arthritis (PsA) is a heterogeneous inflammatory disease with various joint and skin manifestations and multiple associated comorbidities. The management of PsA is important not only in controlling disease activity and preventing subsequent damage but also in improving the quality of life and reducing mortality. Over the years, numerous drugs have been introduced into the therapeutic armamentarium of the disease. While non-steroidal anti-inflammatory drugs (NSAIDs) and conventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) have contributed to management, it was not until the advent of biologics (and later on targeted synthetic DMARDs) that therapy was revolutionized, with the achievement of significantly better clinical and radiographic outcomes. Several drugs and treatment approaches are currently being tested in clinical trials at different phases. Despite all the success, there are still various challenges and unmet needs in the field of PsA, reflected by difficult-to-treat disease course, secondary failure of therapy, and lack of consensus on accepted treatment withdrawal protocols, among others. In this review, we have discussed the most recent advances in the therapy of psoriatic disease, with a particular focus on phase III studies completed (or ongoing) since 2020. We also mentioned the challenges and unmet needs in our clinical practice, which we expect current and future research to provide answers to., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Psoriatic arthritis is an inflammatory arthritis that affects around 30% of patients with psoriasis. The disease spectrum includes peripheral arthritis, enthesitis, tenosynovitis, dactylitis, axial involvement, and skin and nail psoriasis in most patients. In addition to the cutaneous and musculoskeletal manifestations, several comorbidities can complicate the disease course, including cardiovascular disease, diabetes mellitus, metabolic syndrome, gout, anxiety, and depression. The management of patients with psoriatic arthritis begins with a careful assessment of the skin and joints and screening for comorbidities. This review describes the assessment tools and outcome measures used in the evaluation of patients with psoriatic arthritis. It summarizes the approach to therapy, including non-medicinal interventions such as education, lifestyle changes, physiotherapy, and occupational therapy. It discusses the evidence on pharmacologic treatments, including drugs used for symptomatic relief such as non-steroidal anti-inflammatory drugs, and those used to control the disease process; this last group comprises conventional synthetic disease modifying anti-rheumatic drugs (DMARDs), including methotrexate, leflunomide, and sulfasalazine, and biologic and targeted DMARDs, including anti-tumor necrosis factor (TNFα), anti-interleukin-17 (IL-17), anti-IL-12/23, and anti-IL-23 agents, as well as Janus kinase (JAK) inhibitors and phosphodiesterase 4 (PDE4) antagonists. Although these drugs are usually tailored to the clinical profile of the patient, biomarkers predictive of response to therapy are needed so that a more personalized approach can be followed., Competing Interests: Competing interests: We have read and understood the BMJ policy on declaration of interests and declare the following interests: DDG is a consultant to Abbvie, Amgen, BMS, Eli Lilly, Janssen, Novartis, Pfizer, and UCB and has received grant support from Abbvie, Amgen, Eli Lilly, Novartis, Pfizer, and UCB., (Published by the BMJ Publishing Group Limited.

Objectives: Chronic kidney disease (CKD) is a comorbidity in psoriatic arthritis (PsA). We aimed to define the prevalence of CKD in patients with PsA, describe their long-term renal outcomes and identify risk factors for CKD development., Methods: We included patients with PsA followed by our prospective observational cohort. We defined CKD as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m 2 for at least 3 months. We characterised long-term renal outcomes of CKD cases identified following clinic entry. We used time-dependent Cox regression models to identify factors associated with CKD development., Results: Of 1336 patients included in the study, 123 (9.2%) had CKD. Of these, 25 (20.3%) were observed to have CKD at clinic entry and 98 (79.7%) developed CKD during follow-up at a median (IQR) of 8.2 (2.8-14.0) years from baseline. Doubling of baseline creatinine was observed in 18 of 98 (18.3%) new patients with CKD. 49 (50%) patients developed a sustained ≥40% reduction in baseline eGFR. Two patients developed eGFR <15 mL/min/1.73 m 2 . In the multivariate Cox regression model adjusted for age at study entry, sex and baseline eGFR, factors independently associated with the development of CKD included diabetes mellitus (HR 2.58, p<0.001), kidney stones (HR 2.14, p=0.01), radiographic damaged joint count (HR 1.02, p=0.02), uric acid (HR 1.21, p<0.001; 50-unit increase), daily use of non-steroidal anti-inflammatory drugs (NSAIDs) (HR 1.77, p=0.02) and methotrexate use (HR 0.51, p=0.01)., Conclusion: CKD is not infrequent in PsA. Its development is associated with related comorbidities, joint damage and NSAID use. Methotrexate seems to be protective., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024. Re-use permitted under CC BY-NC. No commercial re-use.

Objectives: Proteinuria is a marker of lupus nephritis (LN) activity and damage. We aimed to explore the impact of baseline proteinuria level on long-term outcomes., Methods: We included 249 patients diagnosed with their first biopsy-proven LN. We divided patients based on baseline proteinuria into low-level (≤1 g/day, group 1; 62 patients), moderate-level (>1 and <3 g/day, group 2; 90 patients), and high-level proteinuria (≥3 g/day, group 3; 97 patients). Outcomes included complete proteinuria recovery (CPR) at 1 year, an adverse composite outcome (ESKD, a sustained ≥40% decline in eGFR, or death), and LN flares. Cox proportional hazard models were used to examine the association between baseline characteristics and long-term outcomes., Results: At baseline, the median [IQR] age was 33.2 [26.4, 42.4] years; median proteinuria level was 2.2 [1.0, 3.8] g/day. 177 (71%) patients had proliferative lesions on biopsy; 59.7% in group 1, 78.9% in group 2, and 71.4% in group 3.The rate of achievement of CPR at 1 year was highest for group 1 and lowest for group 3. For long-term outcomes (median follow-up 8.4 years), the frequency of the adverse composite outcome was 27.4%, 26.7%, and 48.5% in groups 1, 2, and 3, respectively; p= 0.003. The corresponding frequency of flares was 27.4%, 38.2%, and 61.9%, respectively; p< 0.001. In the multivariable model for factors associated with long-term outcomes, there was no significant difference between groups 1 and 2; group 3 was associated with the worst prognosis., Conclusions: Low-level proteinuria is commonly associated with proliferative LN and adverse long-term outcomes., (© The Author(s) 2024.

Objectives: Membranous lupus nephritis (MLN) is thought to have a more benign course than proliferative lupus nephritis (PLN). We aimed to determine the differences in short and long-term outcomes between patients with MLN and PLN., Methods: We included patients with first biopsy-proven MLN and PLN. Short-term outcomes included complete proteinuria recovery (CPR), complete renal response (CRR), and primary efficacy renal response (PERR). Long-term outcomes included a sustained ≥40% reduction in baseline estimated glomerular filtration rate (eGFR), end-stage kidney disease (ESKD), cardiovascular (CV) events, ≥2 increase in SDI, and death. Univariable and multivariable Cox proportional hazard models were used to examine the effect of baseline characteristics on long-term outcomes., Results: Of 215 patients, 51 had pure MLN, and 164 had PLN. We found no significant differences between the two groups in achieving CPR, CRR, and PERR at 1 and 2 years. Median time to outcomes was slightly, but insignificantly, longer in the MLN group.For long-term outcomes, PLN was associated with worse renal and non-renal outcomes, but this was not statistically significant.In the multivariable Cox proportional hazard models, ESKD was associated with the following baseline variables: younger age (HR 0.92, 95% CI 0.87-0.97), higher creatinine (HR 1.01, 95% CI 1.01-1.02), low complement (HR 4.0, 95% CI 1.04-11.10), and higher chronicity index (HR 1.28, 95% CI 1.08-1.51)., Conclusion: The resolution of proteinuria in LN is slow. MLN is not a benign disease and may be associated with deterioration of renal function, ESKD, damage, CV events, and death., (© The Author(s) 2024.

Objectives: Higher-level evidence is required to discern whether the incidence of idiopathic inflammatory myopathies (IIM) has increased during the COVID-19 pandemic and whether the disease pattern and course have changed. We aimed to analyse patients who were diagnosed with IIM at our tertiary care centre during the pandemic and compare them with IIM patients diagnosed before COVID-19., Methods: We retrospectively analysed the medical records of adult patients (>18 years) who were diagnosed with IIM during COVID-19 versus a control group of patients diagnosed before the outbreak. Included were patients whose diagnosis was made at the Department of Medicine and Rheumatology Unit of Hadassah Medical Center, Jerusalem, Israel. We also conducted a comprehensive review of the literature regarding SARS-CoV-2 infection and vaccine-induced IIM., Results: Our study yielded 18 and 16 diagnosed IIM patients over periods of 27 and 56 months in the COVID-19 and pre-pandemic cohorts, respectively. These constitute incidence rates of 0.66 and 0.28 patients/month, respectively, marking an increased rate in the COVID-19 group. Unique features were noted in IIM patients who were diagnosed during the pandemic. This includes male predominance (M:F ratio of 12:6), higher hospitalisation rate (0.77 vs. 0.43 admitted/total patients) and increased number of patients with CPK >10,000 U/L (3 vs. 1 patient). Despite the more severe presentation and course in the pandemic group, survival was comparable between the groups., Conclusions: The incidence of IIM increased during the COVID-19 pandemic. These patients display unique features and a more severe presentation. Fortunately, the prognosis remains unchanged.

Familial Mediterranean fever (FMF) is a hereditary auto-inflammatory disease, characterised by recurrent episodes of fever and serositis. Since 1972, colchicine is the drug of choice for FMF. It is effective in preventing the attacks and withholding amyloidosis in most patients with FMF. Colchicine blood and tissue levels are regulated by a glycoprotein pump (GLP) and by Cytochrome P450 3A4 (CYP450 3A4). It is secreted through the bile system and the kidneys. Over the years several problems have been raised following the use of colchicine in FMF. These include potential side effects (particularly gastrointestinal), non-compliance, inefficacy due to drug resistance, many drug-drug interactions and high risk for intoxication due to a narrow therapeutic range. In addition, colchicine does not prevent protracted febrile myalgia or exertional leg pain. Based upon our current understanding of the pathogenesis of FMF, it seems that anti-interleukin-1 (anti-IL-1) agents can solve many of the aforementioned problems related to colchicine therapy. The gastrointestinal side effects of colchicine are extremely uncommon with anti-IL-1 biologics. Drug-drug interactions are also unlikely, and their therapeutic window is not narrow. The once daily injection of anakinra, the once weekly injection of rilonacept, and the once monthly injection of canakinumab result in a better compliance to therapy. Nevertheless, there are no controlled trials showing the efficacy of anti-IL-1 agents in preventing amyloidosis or their safety in pregnancy. Therefore, it is still needed to give IL-1 blockers with concomitant colchicine in its tolerable dose effective in preventing amyloidosis (1.5 mg daily in adult).

Introduction: Vaccination represents a cornerstone in mastering the COVID-19 pandemic. Data on immunogenicity and safety of messenger RNA (mRNA) vaccines in patients with autoimmune inflammatory rheumatic diseases (AIIRD) are limited., Methods: A multicentre observational study evaluated the immunogenicity and safety of the two-dose regimen BNT162b2 mRNA vaccine in adult patients with AIIRD (n=686) compared with the general population (n=121). Serum IgG antibody levels against SARS-CoV-2 spike S1/S2 proteins were measured 2-6 weeks after the second vaccine dose. Seropositivity was defined as IgG ≥15 binding antibody units (BAU)/mL. Vaccination efficacy, safety, and disease activity were assessed within 6 weeks after the second vaccine dose., Results: Following vaccination, the seropositivity rate and S1/S2 IgG levels were significantly lower among patients with AIIRD versus controls (86% (n=590) vs 100%, p<0.0001 and 132.9±91.7 vs 218.6±82.06 BAU/mL, p<0.0001, respectively). Risk factors for reduced immunogenicity included older age and treatment with glucocorticoids, rituximab, mycophenolate mofetil (MMF), and abatacept. Rituximab was the main cause of a seronegative response (39% seropositivity). There were no postvaccination symptomatic cases of COVID-19 among patients with AIIRD and one mild case in the control group. Major adverse events in patients with AIIRD included death (n=2) several weeks after the second vaccine dose, non-disseminated herpes zoster (n=6), uveitis (n=2), and pericarditis (n=1). Postvaccination disease activity remained stable in the majority of patients., Conclusion: mRNA BNTb262 vaccine was immunogenic in the majority of patients with AIIRD, with an acceptable safety profile. Treatment with glucocorticoids, rituximab, MMF, and abatacept was associated with a significantly reduced BNT162b2-induced immunogenicity., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2021.
