ABSTRACT
Sarcoidosis is a systemic inflammatory disease of unknown origin, which consists of the formation of multiple sterile noncaseating granulomas. Inhaled antigens are believed to initiate disease in prone individuals, considering that almost all patients present pulmonary or mediastinal lymph node disease. Extrapulmonary manifestations are common and diverse: practically any organ system can be affected, and treatment can range from simple watchful waiting to intense immunosuppression. In this article, we review current concepts about sarcoidosis in an overview, focusing on recognition and treatment of its major clinical phenotypes.

Systemic autoinflammatory diseases (SAIDs) arise from dysregulated innate immune system activity, which leads to systemic inflammation. These disorders, encompassing a diverse array of genetic defects classified as inborn errors of immunity, are significant diagnostic challenges due to their genetic heterogeneity and varied clinical presentations. Although recent advances in genetic sequencing have facilitated pathogenic gene discovery, approximately 40% of SAIDs patients lack molecular diagnoses. SAIDs have distinct clinical phenotypes, and targeted therapeutic approaches are needed. This review aims to underscore the complexity and clinical significance of SAIDs, focusing on prototypical disorders grouped according to their pathophysiology as follows: (i) inflammasomopathies, characterized by excessive activation of inflammasomes, which induces notable IL-1ß release; (ii) relopathies, which are monogenic disorders characterized by dysregulation within the NF-κB signaling pathway; (iii) IL-18/IL-36 signaling pathway defect-induced SAIDs, autoinflammatory conditions defined by a dysregulated balance of IL-18/IL-36 cytokine signaling, leading to uncontrolled inflammation and tissue damage, mainly in the skin; (iv) type I interferonopathies, a diverse group of disorders characterized by uncontrolled production of type I interferons (IFNs), notably interferon α, ß, and ε; (v) anti-inflammatory signaling pathway impairment-induced SAIDs, a spectrum of conditions characterized by IL-10 and TGFß anti-inflammatory pathway disruption; and (vi) miscellaneous and polygenic SAIDs. The latter group includes VEXAS syndrome, chronic recurrent multifocal osteomyelitis/chronic nonbacterial osteomyelitis, Schnitzler syndrome, and Still's disease, among others, illustrating the heterogeneity of SAIDs and the difficulty in creating a comprehensive classification. Therapeutic strategies involving targeted agents, such as JAK inhibitors, IL-1 blockers, and TNF inhibitors, are tailored to the specific disease phenotypes.

OBJECTIVE: To review current literature to support the use of mesna as a preventive therapy for hemorrhagic cystitis and bladder cancer in patients with systemic autoimmune diseases and systemic vasculitis treated with cyclophosphamide. MATERIALS AND METHODS: The search for articles was conducted systematically through MEDLINE, LILACS, Cochrane Library, and Embase databases. Only articles in English were selected. For available records, titles and abstracts were selected independently by two investigators. RESULTS: Eighteen studies were selected for analysis. The known adverse effects of cyclophosphamide were hematological toxicity, infections, gonadal toxicity, teratogenicity, increased risk for malignancy and hemorrhagic cystitis. Long-term toxicity was highly dependent on cyclophosphamide cumulative dose. The risk of bladder cancer is especially higher in long-term exposure and with cumulative doses above 36 g. The risk remains high for years after drug discontinuation. Hemorrhagic cystitis is highly correlated with cumulative dose and its incidence ranges between 12 and 41%, but it seems to be lower with new regimens with reduced cyclophosphamide dose. No randomized controlled trials were found to analyze the use of mesna in systemic autoimmune rheumatic diseases and systemic vasculitis. Retrospective studies yielded conflicting results. Uncontrolled prospective studies with positive results were considered at high risk of bias. No evidence was found to support the use of mesna during the treatment with cyclophosphamide for autoimmune diseases or systemic vasculitis to prevent hemorrhagic cystitis and bladder cancer. In the scenarios of high cumulative cyclophosphamide dose (i.e., > 30 g), patients with restricted fluid intake, neurogenic bladder, therapy with oral anticoagulants, and chronic kidney disease, mesna could be considered. CONCLUSION: The current evidence was found to be insufficient to support the routine use of mesna for the prophylaxis of hemorrhagic cystitis and bladder cancer in patients being treated for systemic autoimmune diseases and systemic vasculitis with cyclophosphamide. The use may be considered for selected cases.

Immunoglobulin G4-related disease is a systemic immune-mediated disease with insidious evolution characterized by fibroinflammatory lesions over virtually any organ system. Despite the remarkable progression of knowledge, its etiology remains undefined. Due to its relapse-remitting pattern, it could accumulate irreversible damage, increasing comorbidities and mortality. This paper emphasizes key concepts for diagnosing and treating patients with this condition.

Relapsing polychondritis is a rare multisystem disease involving cartilaginous and proteoglycan-rich structures. The diagnosis of this disease is mainly suggested by the presence of flares of inflammation of the cartilage, particularly in the ears, nose or respiratory tract, and more rarely, in the presence of other manifestations. The spectrum of clinical presentations may vary from intermittent episodes of painful and often disfiguring auricular and nasal chondritis to an occasional organ or even life-threatening manifestations such as lower airway collapse. There is a lack of awareness about this disease is mainly due to its rarity. In 2020, VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome, a novel autoinflammatory syndrome, was described. VEXAS syndrome is attributed to somatic mutations in methionine-41 of UBA1, the major E1 enzyme that initiates ubiquitylation. This new disease entity connects seemingly unrelated conditions: systemic inflammatory syndromes (relapsing chondritis, Sweet's syndrome, and neutrophilic dermatosis) and hematologic disorders (myelodysplastic syndrome or multiple myeloma). Therefore, this article reviews the current literature on both disease entities.

Hereditary connective tissue disorders include more than 200 conditions affecting different organs and tissues, compromising the biological role of the extracellular matrix through interference in the synthesis, development, or secretion of collagen and/or its associated proteins. The clinical phenotype includes multiple signs and symptoms, usually nonspecific but of interest to rheumatologists because of musculoskeletal involvement. The patient´s journey to diagnosis is long, and physicians should include these disorders in their differential diagnoses of diseases with systemic involvement. In this review, insights for the diagnosis and treatment of osteogenesis imperfecta, hypermobility spectrum disorder/Ehlers-Danlos syndrome, Marfan, Loeys-Dietz, and Stickler syndromes are presented.

Despite their rarity, Lyme disease and Whipple's disease are of significant importance in rheumatology, as both can manifest as chronic arthritis, presenting challenges in the differential diagnosis of inflammatory arthropathies. In Lyme disease, arthritis typically emerges as a late manifestation, usually occurring six months after the onset of erythema migrans. The predominant presentation involves mono- or oligoarthritis of large joints, with a chronic or remitting-recurrent course. Even with appropriate antimicrobial treatment, arthritis may persist due to inadequate immunological control triggered by the disease. In contrast, Whipple's disease may present with a migratory and intermittent seronegative poly- or oligoarthritis of large joints, preceding classic gastrointestinal symptoms by several years. Both disorders, particularly Whipple's disease, can be misdiagnosed as more common autoimmune rheumatic conditions such as rheumatoid arthritis and spondyloarthritis. Epidemiology is crucial in suspecting and diagnosing Lyme disease, as the condition is transmitted by ticks prevalent in specific areas of the United States, Europe, and Asia. On the contrary, the causative agent of Whipple's disease is widespread in the environment, yet invasive disease is rare and likely dependent on host genetic factors. In addition to erythema migrans in Lyme disease and gastrointestinal manifestations in Whipple's disease, neurological and cardiac involvement can further complicate the course of both. This article offers a comprehensive review of the epidemiological, pathophysiological, clinical, and therapeutic aspects of both diseases.

ABSTRACT
BACKGROUND: Early rheumatoid arthritis (RA) offers an opportunity for better treatment outcomes. In real-life settings, grasping this opportunity might depend on access to specialized care. We evaluated the effects of early versus late assessment by the rheumatologist on the diagnosis, treatment initiation and long-term outcomes of RA under real-life conditions. METHODS: Adults meeting the ACR/EULAR (2010) or ARA (1987) criteria for RA were included. Structured interviews were conducted. The specialized assessment was deemed "early" when the rheumatologist was the first or second physician consulted after symptoms onset, and "late" when performed afterwards. Delays in RA diagnosis and treatment were inquired. Disease activity (DAS28-CRP) and physical function (HAQ-DI) were evaluated. Student's t, Mann-Whitney U, chi-squared and correlation tests, and multiple linear regression were performed. For sensitivity analysis, a propensity score-matched subsample of early- vs. late-assessed participants was derived based on logistic regression. The study received ethical approval; all participants signed informed consent. RESULTS: We included 1057 participants (89.4% female, 56.5% white); mean (SD) age: 56.9 (11.5) years; disease duration: 173.1 (114.5) months. Median (IQR) delays from symptoms onset to both RA diagnosis and initial treatment coincided: 12 (6-36) months, with no significant delay between diagnosis and treatment. Most participants (64.6%) first sought a general practitioner. Notwithstanding, 80.7% had the diagnosis established only by the rheumatologist. Only a minority (28.7%) attained early RA treatment (≤ 6 months of symptoms). Diagnostic and treatment delays were strongly correlated (rho 0.816; p < 0.001). The chances of missing early treatment more than doubled when the assessment by the rheumatologist was belated (OR 2.77; 95% CI: 1.93, 3.97). After long disease duration, late-assessed participants still presented lower chances of remission/low disease activity (OR 0.74; 95% CI: 0.55, 0.99), while the early-assessed ones showed better DAS28-CRP and HAQ-DI scores (difference in means [95% CI]: -0.25 [-0.46, -0.04] and - 0.196 [-0.306, -0.087] respectively). The results in the propensity-score matched subsample confirmed those observed in the original (whole) sample. CONCLUSIONS: Early diagnosis and treatment initiation in patients with RA was critically dependent on early access to the rheumatologist; late specialized assessment was associated with worse long-term clinical outcomes.

BACKGROUND: Management delays imply worse outcomes in rheumatoid arthritis (RA) and, therefore, should be minimized. We evaluated changes in diagnostic and treatment delays regarding RA in the last decades in Brazil. METHODS: Adults fulfilling the ACR/EULAR (2010) criteria for RA were assessed. Delays in diagnosis and treatment, and the frequencies of early management initiation within thresholds (windows of opportunity) of 3, 6, and 12 months from symptoms onset were evaluated. The Mann-Kendall trend test, chi-squared tests with Cramer's V effect sizes and analysis of variance were conducted. RESULTS: We included 1116 patients: 89.4% female, 56.8% white, mean (SD) age 57.1 (11.5) years. A downward trend was found in diagnostic (tau = - 0.677, p < 0.001) and treatment (tau = - 0.695, p < 0.001) delays from 1990 to 2015. The frequency of early management increased throughout the period, with ascending effect sizes across the 3-, 6-, and 12-month windows (V = 0.120, 0.200 and 0.261, respectively). Despite all improvements, even in recent years (2011-2015) the diagnostic and treatment delays still remained unacceptably high [median (IQR): 8 (4-12) and 11 (5-17) months, respectively], with only 17.2% of the patients treated within the shortest, 3-month window. CONCLUSION: The delays in diagnosis and treatment of RA decreased during the last decades in Brazil. Improvements (effect sizes) were greater at eliminating extreme delays (≥ 12 months) than in attaining really short management windows (≤ 3 months). Very early treatment was still an unrealistic goal for most patients with RA.

ABSTRACT
Rheumatoid arthritis (RA) is a chronic and autoimmune systemic inflammatory disease that can cause irreversible joint deformities, with increased morbidity and mortality and a significant impact on the quality of life of the affected individual. The main objective of RA treatment is to achieve sustained clinical remission or low disease activity. However, up to 40% of patients do not respond to available treatments, including bDMARDs. New therapeutic targets for RA are emerging, such as Janus kinases (JAKs). These are essential for intracellular signaling (via JAK-STAT) in response to many cytokines involved in RA immunopathogenesis. JAK inhibitors (JAKi) have established themselves as a highly effective treatment, gaining increasing space in the therapeutic arsenal for the treatment of RA. The current recommendations aim to present a review of the main aspects related to the efficacy and safety of JAKis in RA patients, and to update the recommendations and treatment algorithm proposed by the Brazilian Society of Rheumatology in 2017.

BACKGROUND: Rheumatoid arthritis (RA) is a common autoimmune systemic inflammatory disease. In addition to joint involvement, RA patients frequently have other comorbidities, such as cardiovascular diseases. Drugs used for RA treatment may increase or decrease the risk of a cardiovascular event. This study aims to analyze cardiovascular risk comorbidities in patients with RA and the correlation with the use of anti-rheumatic drugs. METHODS: Cross-sectional study conducted based on the real-life rheumatoid arthritis study database - REAL, a prospective observational cohort study. Associations between the use of anti-rheumatic drugs and the presence of comorbidities were represented by their prevalence ratio and evaluated using the Chi-square or Fisher's Exact tests. RESULTS: We assessed 1116 patients, 89.4% women, mean age of 55.15 years and predominance of seropositive disease. 63.3% had some cardiovascular comorbidity, predominantly hypertension (49.9%). The use of glucocorticoids was observed in 47.4% of patients and there was a significant tendency of lower use of these drugs in the presence of dyslipidemia (PR: 0.790; p = 0.007). We observed that the presence of cardiovascular comorbidities was associated with higher use of bDMARDs (PR:1.147; p = 0.003). CONCLUSIONS: The presence of cardiovascular risk comorbidities was confirmed to be higher in RA patients. Different treatment strategies using less glucocorticoids in the presence of dyslipidemia and more common use of bDMARDs in patients with cardiovascular comorbidities suggest that rheumatologists are aware of the potential influence of the DMARDs in the risk of cardiovascular event. Reinforcing these results, we highlight the need for a better baseline assessment to guide the choice of anti-rheumatic drugs in RA patients who have comorbidities.

BACKGROUND: Chronic prostatitis has been a common disease reported with high frequency in ankylosing spondylitis (AS) even from decades ago. Infectious (Chlamydia trachomatis) or non-infectious (uric acid) prostatitis can hypothetically trigger vertebral inflammation in AS. This study aimed to assess the features of chronic prostatitis in patients with AS compared to healthy controls. METHODS: A cross-sectional study including male patients with AS and healthy controls who agreed to undergo a prostate examination was conducted. Structured clinical interviews, prostate physical examinations, and cytological, biochemical, and microbiological tests on urinary samples collected before and after standardized prostatic massage (pre- and post-massage test) were performed. RESULTS: Ninety participants (45 AS patients, mean age: 52.5 ± 10.0 years, with longstanding disease, 12.4 ± 6.9 years, and 45 controls, mean age: 52.8 ± 12.1 years) were included. National Institutes of Health - Chronic Prostatitis Symptom Index (NIH-CPSI) scores were similar in the AS and control groups (4.0 [1.0-12.0] vs. 5.0 [1.0-8.5], p = 0.994). The frequencies of symptoms of chronic prostatitis (NIH-CPSI Pain Domain ≥4) were also similar in both groups (23.3% vs. 22.7%, p = 0.953). Results of polymerase chain reaction tests for Chlamydia trachomatis were negative in all tested urinary samples, and uric acid concentrations and leukocyte counts were similar in all pre- and post-massage urinary samples. CONCLUSIONS: In this study, chronic prostatitis occurred in male patients with AS, but its frequency and characteristics did not differ from those found in the healthy male population of similar age.

Background Rheumatoid arthritis is a chronic, autoimmune disease in which treatment has evolved with a variety of therapeutic classes. Biological disease-modifying antirheumatic drugs have improved therapy; however, the continued long-term use of these drugs with sustained safety and efficacy remains a challenge. ObjectiveThe objective of this study was to analyze time of use and reasons for discontinuation of biological disease-modifying antirheumatic drugs in patients with rheumatoid arthritis.SettingIt is as part of REAL (Rheumatoid Arthritis in Real Life), a multicenter project that evaluated Brazilian patients with rheumatoid arthritis in a real-life setting. Eleven referral centers for the treatment in the public network participated in the study.MethodsWe conducted a cross-sectional analysis of data collected in the REAL study from August to October 2015 study. The patients were submitted to clinical evaluation and analysis of medical records.Results1125 patients were included (89.5% women; median age: 56.6 years; and disease time: 12.8 years). A total of 406 (36.09%) participants were on a biological disease-modifying antirheumatic drugs. Infliximab was the drug with the longest time of use (12 years). Most (64.4%) drug suspension episodes were due to inefficacy. Adalimumab and certolizumab had a greater number of suspensions due to primary inefficacy, while discontinuations for abatacept were due more to secondary inefficacy. Infliximab had fewer suspensions due to primary inefficacy and golimumab had fewer episodes of secondary inefficacy. Regarding side effects, infliximab was suspended a greater number of times because of clinical and laboratory side effects. Abatacept and adalimumab had fewer suspensions due to clinical side effects, and certolizumab, rituximab and tocilizumab had fewer laboratory adverse effects. Conclusion Among the biological disease-modifying antirheumatic drugs being used for long periods, infliximab had greater time of use. Most drug suspensions (64%) were due to primary or secondary inefficacy. Number of discontinuations due to clinical and laboratory adverse effects for each drug was analyzed, and these data should be confirmed by other real-life studies. Knowledge of what is happening in real life is essential to health professionals, who need to be aware of the most common adverse effects and to health managers, who aim for greater cost-effectiveness in the choice of medications.

BACKGROUND: The interferon pathways have been commonly implicated in autoimmune disease development but the identity of the genes involved has not yet been fully clarified. Variation in genes involved in interferon pathways is expected to have a role in the etiology of these diseases. METHODS: The potential association of a polymorphism in the IL28RA gene, involved in these pathways, with susceptibility to systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA) and disease-related phenotypes was investigated in 603 Brazilian individuals (354 well-characterized SLE and RA patients, and 249 controls). IL28RA (rs4649203) variant was genotyped by TaqMan assay. Statistical analysis was performed including both diseases and a comprehensive list of patient clinical manifestations. RESULTS: The rs4649203-G (minor) allele was associated with SLE and RA occurrence and was shown to be a risk factor for serositis and anemia among SLE patients as well as a protective factor for rheumatoid vasculitis and rheumatoid nodules in RA patients, suggesting an association with a milder form of the disease. CONCLUSIONS: The IL28RA gene may contribute to SLE and RA susceptibility and to specific clinical manifestations of the diseases.

ABSTRACT
BACKGROUND: In Brazil, socioeconomic differences in the incidence of rheumatoid arthritis (RA) have been demonstrated, which are important in the formulation of hypotheses regarding the association between environmental factors, lifestyle and the risk of disease development. This study examines how the socioeconomic condition of the patient with RA in Brazil, assessed according to social class, educational level, employment situation and use of caregivers, affects the times between the beginning of symptoms and diagnosis and the beginning of the use of disease-modifying antirheumatic drugs, as well as the presence of erosive disease and functional status. METHODS: This work is part of a multicentric study called REAL - Rheumatoid Arthritis in Real Life in Brazil, which is a prospective observational cohort study. RESULTS: As described in the REAL study, we included a total of 1115 patients. It was noted that patients with an educational classification of up to second grade incomplete presented with erosion percentages above those with a higher grade complete. Patients with caregivers presented a higher percentage of erosion than patients without caregivers. We verified that patients from economic classes above B2 presented fewer occurrences of erosion than those from classes C2, D-E. We also analyzed the average time differences from the beginning of symptoms and diagnosis and the beginning of treatment, according to academic level, erosion and economic classification. Patients with first grade complete showed an HAQ-DI averages higher than those with second grade complete. The patients who had employment showed lower HAQ-DI averages than patients who were not employed. The patients with erosion showed an HAQ-DI value higher than those without erosion. Patients with caregivers showed an HAQ-DI average higher than that of without caregivers. CONCLUSION: This study showed that the therapeutic window of RA is not being reached, and therefore we should have a policy to expand and ensure access to public health for all patients, especially those with lower levels of education and income. TRIAL REGISTRATION: This study was approved by the National Commission of Ethics in Research.
