RESUMO
OBJECTIVES: In the current study, we aimed to investigate the effect of smoking on inadequate response to methotrexate (MTX-IR) in rheumatoid arthritis (RA) patients. METHODS: We searched PubMed, Embase, and Web of Science until 6 June 2022. Observational or interventional studies investigating MTX-IR in RA patients based on smoking status were included. Two independent reviewers assessed the risk of bias and the certainty of the evidence using the Risk of Bias in Nonrandomized Studies-of Interventions and Grades of Recommendation, Assessment, Development, and Evaluation tools, respectively. RESULTS: We included 23 studies in the systematic review and 13 in the meta-analysis. Of the 13 included studies, 6 had a moderate risk, 3 had a serious risk, and 4 had a critical risk of bias. The overall random-effect meta-analysis suggested that smokers were 58% more likely to be MTX-IR when compared with nonsmokers [odds ratio (OR) 1.58, 95% confidence interval 1.21-2.06; P = .001; I2 = 69.3%]. The common-effect meta-analysis of the adjusted ORs demonstrated an overall OR of 2.69 (1.88-3.83; P < .001; I2 = 27.1%). CONCLUSIONS: The current study showed that smoking is a significant predictor of MTX-IR, especially in disease-modifying antirheumatic drug-naïve early RA patients, as most of the included studies in the meta-analysis consisted of this population.

Coronavirus Disease 2019 (COVID-19) is a viral infection caused by SARS-CoV-2, which can trigger autoimmune diseases such as antineutrophilic cytoplasmic antibody (ANCA) associated vasculitis (AAV) that affect small and medium-sized blood vessels in multiple organs. This study discusses a case with neuropathy and positive ANCA after COVID-19 infection and reviews the literature on AAV following COVID-19 infection. A 59-year-old man is presented that was referred to Shariati Hospital for evaluation of neurologic problems after a COVID-19 infection. Initially, he had flu-like symptoms. A few days later, he developed right distal upper and lower limb paresthesia. His electromyography (EMG) and nerve conduction velocity (NCV) results were consistent with polyneuropathy. Lumbar puncture (LP) was normal except for positive COVID-19 polymerase chain reaction (PCR). The patient's paresthesia worsened. Laboratory data showed leukocytosis, anemia, thrombocytosis, high erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP). Perinuclear anti-neutrophil cytoplasmic antibody (MPO-ANCA) was positive. According to the results, vasculitis was the main differential diagnosis. The sural nerve biopsy was performed, and the result was consistent with small to medium-sized vessel vasculitis. The patient was diagnosed with COVID-induced AAV. He was prescribed methylprednisolone and cyclophosphamide and was discharged with prednisolone and cotrimoxazole. In this study, a unique case of AAV induced by COVID-19 infection confirmed by nerve biopsy is presented. A review of the literature found 48 cases of new-onset AAV in adults and pediatrics after COVID-19 infection. Further research is needed to completely understand the relationship between COVID-19.
RESUMO
BACKGROUND: Systemic sclerosis is a multiorgan autoimmune disease that can overlap with other rheumatologic disorders; however, co-occurrence with antineutrophil cytoplasmic antibody-associated vasculitis is rare. CASE PRESENTATION: A 39-year-old Persian female patient with systemic sclerosis according to American College of Rheumatology/European League Against Rheumatism 2013 criteria with a disease duration of 6 years was admitted to the hospital due to a rise in creatinine level in July 2021. She had complaints of nasal speech and feeling of nasal perforation. The first symptoms of antineutrophil cytoplasmic antibody-associated vasculitis had started 5 years earlier with palpable purpura in the lower limbs, hemoptysis, and positive perinuclear (p)-antibody-associated vasculitis level (> 300 AU/mL). Still, the diagnosis was not achieved due to the patient's reluctance to undergo a biopsy. She was treated with azathioprine (150 mg/day) and prednisolone (10 mg/day) during the 5-year follow-up. Her renal biopsy results showed cortical renal tissue with a cellular crescent in more than 50% of the specimen, rupture of the Bowman capsule and the glomerular basement membrane, peri-glomerular inflammation, and mild tubular atrophy in microscopic examinations. The immunofluorescence study resulted in a granular pattern of immune deposits along the glomerular basement membrane, mesangial tissue, and tubular basement membranes. CONCLUSION: We reported a rare case of comorbid systemic sclerosis and antineutrophil cytoplasmic antibody-associated vasculitis with nasal perforation. Her renal biopsy showed immune deposits along the glomerular basement membrane, mesangial tissue, and tubular basement membranes. Overlapping with other collagen vascular diseases can occur in rheumatology patients with uncommon manifestations. In systemic sclerosis, renal involvement in the form of glomerulonephritis is infrequent, and comorbid systemic lupus erythematosus or antineutrophil cytoplasmic antibody-associated vasculitis should be considered.

OBJECTIVES: Interstitial lung disease (ILD) is an important manifestation of autoimmune diseases that can lead to morbidity and mortality. Although several autoantibodies have been linked with ILD presentation and adverse outcomes, the association of anti-Ro52 antibody with ILD is less studied. Hence, we investigated this association in various autoimmune diseases in the current study. DESIGN: We designed a systematic review and meta-analysis and did a comprehensive search from inception until 2 January 2023. DATA SOURCES: A systematic search was conducted in four electronic databases: PubMed, Web of Science, Scopus and Embase. ELIGIBILITY CRITERIA: Observational studies that reported ILD diagnosis (outcome) and anti-Ro antibody (exposure) status in any autoimmune conditions (population) were included. The association between rapidly progressive ILD (RP-ILD) and anti-Ro52 was studied in idiopathic inflammatory myopathies (IIM). DATA EXTRACTION AND SYNTHESIS: Collected data included study characteristics and ORs with 95% CIs. Quality assessment was performed using a modified version of the Newcastle-Ottawa Scale for cross-sectional studies. Random effects meta-analysis was used to pool the effect estimates. RESULTS: A total of 2353 studies were identified, from which 59 articles met the eligibility criteria. Anti-Ro52/SSA positivity was associated with ILD in all autoimmune disease subgroups: IIM (OR=3.08; 95% CI: 2.18 to 4.35; p value<0.001; I2=49%), systemic lupus (OR=2.43; 95% CI: 1.02 to 5.79; p=0.046; I2=71%), Sjogren (OR=1.77; 95% CI: 1.09 to 2.87; p=0.021; I2=73%), systemic sclerosis (OR=1.71; 95% CI: 1.04 to 2.83; p=0.036; I2=43%), mixed connective tissue disease (OR=3.34; 95% CI: 1.82 to 6.13; p<0.001; I2=0%). Additionally, anti-Ro52-positive myopathy patients were more likely to have simultaneous RP-ILD (OR=2.69; 95% CI:1.50 to 4.83; p<0.001; I2=71%). CONCLUSION: Anti-Ro52/SSA positivity is associated with a higher frequency of ILD diagnosis in various autoimmune diseases. Anti-Ro52/SSA is also linked with a more severe lung involvement (RP-ILD). Future studies can investigate the benefits of screening for anti-Ro52 and its association with ILD development. PROSPERO REGISTRATION NUMBER: CRD42022381447.

The present study aimed to translate and validate the Scleroderma Health Assessment Questionnaire (SHAQ) for Persian-speaking patients (SHAQ-P), using a cross-sectional study. This cross-sectional study included SSc patients with 2013 ACR/EULAR criteria. The SHAQ was translated using a "forward-backward" method. HAQ-DI and SSc-HAQ scores were calculated from the patient-answered questionnaires. Rheumatology experts assessed the face and content validities of the SHAQ-P. Psychometric properties of the SHAQ-P were then assessed: Structural validity was analyzed using principal component factor analysis. Discriminant and convergent validities were measured on subgroups of the initial patient population. Test-retest reliability was measured on patients who filled the SHAQ-P again after 1 month. The Scale-CVI-average (S-CVI/Ave) score for content validity was 88.7%. Face validity was measured to be 68.17% using the QQ10 questionnaire. Factor analysis revealed a two-factor structure with 20 out of 26 questions loading on the first factor (N = 285). One-way ANOVA showed that patients with a higher number of involved organs had higher average HAQ-DI and SSc-HAQ-scores (N = 60, P = 0.019 and 0.023, respectively). HAQ-DI and SSc-HAQ-scores were significantly correlated with the physical component score of SF36 (N = 31, correlation coefficient = - 0.65 and - 0.72, respectively). Reliability testing after one month demonstrated that HAQ-DI and SSc-HAQ-scores were significantly correlated with their initial (N = 40, correlation coefficient = 0.86 and 0.84, respectively), proving that the Persian SHAQ was a valid and reliable questionnaire to evaluate scleroderma patients' quality of life.

Takayasu arteritis (TA) is a chronic inflammatory disorder characterized by vascular damage and fibrosis in the intima that commonly occurs in the aorta. In many damaged sites in TA patients, natural killer (NK) cells have been shown to be hyperactivated and produce inflammatory cytokines and toxic components. Killer cell immunoglobulin-like receptors (KIRs) are found on NK cells and interact with human leukocyte antigen (HLA) class I ligands to activate or suppress NK cells. The present study assessed the possible role of KIR and their HLA ligand genes in susceptibility to TA in Iranian patients. This case-control study included 50 TA patients and 50 healthy subjects. DNA was extracted from whole peripheral blood samples, and polymerase chain reaction with sequence-specific primers (PCR-SSP) was performed to recognize the presence or absence of polymorphism in 17 KIR genes and 5 HLA class I ligands in each participant. Among the KIR and HLA genes, a significant decrease was detected in the frequency of 2DS4 (full allele) in TA patients (38%) compared with healthy controls (82%) (OR=0.13, 95% CI=0.05-0.34). However, none of the KIR and HLA genotypes or the interactions between these genes were associated with susceptibility to TA. The KIR2DS4 gene might be involved in the regulation of activation as well as the production of cytotoxic mediators of NK cells in patients with TA.

BACKGROUND: The rate of hospital readmission is seen as a measure of quality and accountability. Knowing the risk factors that can be changed could reduce the cost burden on patients with inflammatory bowel disease (IBD) and the health system. METHODS: Retrospective analysis was performed on the data extracted from hospital records during a 4-year period. The study setting encompassed three referral hospitals in Tehran and the south of Iran. The primary outcome was hospital readmission of patients with IBD. The factors associated with binary and categorical dependent variables were analyzed using robust logistic regression and multinomial logistic regression, respectively. The significance level was set at P=0.05. RESULTS: 187 patients were admitted during the 4-year study period for an IBD-related reason, among whom 131 patients (70.1%) had ulcerative colitis (UC), and 56 patients (29.9%) had Crohn's disease (CD). Moreover, 29% (55) of the participants had been readmitted at least once during the study period, and seven patients with IBD had been readmitted five or more times during the study period. Corticosteroids (OR=4.55, 95% confidence interval CI: 1.65- 12.55) and chronic pain (OR=6.65, 95% CI: 1.73-25.62) were two factors associated with their readmission within 90 days. For the patients with five or more times of readmissions, Corticosteroids (RRR=5.68), chronic pain (RRR=5.05), length of hospital stay (RRR=0.69), and age (RRR=0.9) could significantly explain the hospital readmissions. CONCLUSION: About one in seven hospitalizations of patients with IBD leads to 30-day readmission. Moreover, younger patients with IBD and shorter length of hospital stay were more likely to be readmitted five or more times during the study period. The use of corticosteroids and the presence of chronic pain were predictors of 90-day readmission. More studies are needed to detect the best management plan for chronic pains.
RESUMO
BACKGROUND: Since 2019, coronavirus disease 2019 (COVID-19) has been the leading cause of mortality worldwide. AIMS: To determine independent predictors of mortality in COVID-19, and identify any associations between pulmonary disease severity and cardiac involvement. METHODS: Clinical, laboratory, electrocardiography and computed tomography (CT) imaging data were collected from 389 consecutive patients with COVID-19. Patients were divided into alive and deceased groups. Independent predictors of mortality were identified. Kaplan-Meier analysis was performed, based on patients having a troponin concentration>99th percentile (cardiac injury) and a CT severity score ≥18. RESULTS: The mortality rate was 29.3%. Cardiac injury (odds ratio [OR] 2.19, 95% confidence interval [CI] 1.14-4.18; P=0.018), CT score ≥18 (OR 2.24, 95% CI 1.15-4.34; P=0.017), localized ST depression (OR 3.77, 95% CI 1.33-10.67; P=0.012), hemiblocks (OR 3.09, 95% CI 1.47-6.48; P=0.003) and history of leukaemia/lymphoma (OR 3.76, 95% CI 1.37-10.29; P=0.010) were identified as independent predictors of mortality. Additionally, patients with cardiac injury and CT score ≥ 18 were identified to have a significantly shorter survival time (mean 14.21 days, 95% CI 10.45-17.98 days) than all other subgroups. There were no associations between CT severity score and electrocardiogram or cardiac injury in our results. CONCLUSIONS: Our findings suggest that using CT imaging and electrocardiogram characteristics together can provide a better means of predicting mortality in patients with COVID-19. We identified cardiac injury, CT score ≥18, presence of left or right hemiblocks on initial electrocardiogram, localized ST depression and history of haematological malignancies as independent predictors of mortality in patients with COVID-19.

Systemic sclerosis is a rare autoimmune disorder that potentially affects nearly every organ of the body. Malignancies are one of the most common non-systemic sclerosis related cause of mortality. There are controversial findings regarding the cervical cancer rate among these patients, but prolonged immunosuppressive medication makes them more susceptible to cervical cancer. In the present study, we have aimed to investigate the cervical cancer screening result and the Pap test non-adherence risk factors among systemic sclerosis patients. This cross-sectional study was conducted on 100 systemic sclerosis patients. The clinicodemographic variables in addition to cervical cancer risk factors were obtained from the patients. Pap test performed using the liquid-based method. The non-adherence risk factors were determined by univariate and multivariate logistic regression analysis. Benign inflammatory and atrophic changes were reported in 26 and 5%, respectively. None of the cases had abnormal cytological finding. Twenty-two percent of the participants were a routine Pap test performer. According to the multivariate model, higher age was associated with Pap test non-adherence [odds ratio (95% confidence interval): 1.058 (1.010-1.108) and P-value: 0.018]. In the present study, we have shown that compliance with Pap test performing is extremely low among Iranian systemic sclerosis patients. In addition, we have demonstrated that older age is a risk factor for non-adherence. These findings highlighted the crucial role of the physicians in motivating the patients toward cancer screening.
