SARS-CoV-2 seroprevalence in patients with autoimmune rheumatic diseases versus family controls: a multi-city cross-sectional survey.

There is uncertainty regarding the effect of the SARS-CoV-2 infection on patients with autoimmune rheumatic diseases (AIRD) who are on immunosuppressive drugs. We did a multicity cross-sectional seroprevalence study conducted in five different cities in India before COVID-19 immunization. Patients with a diagnosis of AIRD and DMARDs were included. Relatives of the patients, preferably staying in the same household with no known rheumatic diseases served as controls. Serum IgG antibodies to SARS-CoV-2 Receptor Binding Domain (RBD) of the spike protein and nucleoprotein (NP) were assayed in eight hundred and eighty nine sera (subjects with disease = 379 and in subjects without disease = 510). IgG antibodies to either RBD and/or NP were positive in 135 (36%) subjects with AIRD as compared to 196 (38%) controls. The seroprevalence of anti-RBD and anti-NP varied between different cities but was not significantly different between subjects with and without disease in Mumbai, Ahmedabad, Bengaluru and Bhubaneswar. However, the occurrence of IgG antibodies to RBD was significantly (p < 0.05) lower in subjects with disease (28/65;43%) as compared to subjects without disease (42/65;65%) in Kolkata, where the positivity rate was lower in connective tissue disease group than in inflammatory arthritis group. Overall, patients with rheumatic diseases on DMARDs have IgG antibodies to RBD and NP of SARSCoV-2 at a comparable level with that of subjects without disease, but the level of antibodies to RBD is lower in patients with connective tissue disease on immunosuppressive drugs in one centre.

Clinical features, severity and outcome of acute pancreatitis in systemic lupus erythematosus.

Acute pancreatitis (AP) is a rare but life threatening manifestation of Systemic Lupus Erythematosus (SLE). The current study aims to study the clinical characteristics, severity, mortality, and outcome of SLE-related AP in Indian population. We retrospectively reviewed medical records of patients with SLE who had AP in the past. Data from 13 rheumatology centers across India were compiled. All patients satisfied SLICC criteria for SLE and ATLANTA criteria for AP. AP was classified in to mild, moderate and severe using revised Atlanta classification. Patients with known risk factors like gall stone and alcohol were excluded.Sixty-six patients (six, children) were studied. Majority of patients were females (82%). The median age of presentation was 24 (11-63) years and most patients (57.5%) presented within first year of diagnosis of lupus. AP occurred mostly in the setting of active lupus (89%). Active nephritis was seen in 39% while a fourth had CNS disease. Patients with severe AP had lower C3. Ascites and sepsis were most common local and systemic complications, respectively. Mortality was 17%. Hypocalcemia, presence of sepsis and shock predicted mortality. In the multivariate analysis, only presence of shock remained as independent predictor of death (OR 63.0, 95% CI: 5.2-760.3). Pancreatitis is an early manifestation of SLE and is associated with active disease. Significant mortality is seen particularly with severe pancreatitis.

Wegener's granulomatosis--an etiology of acute pancreatitis.

Wegener's granulomatosis is a systemic disease that usually involves the upper respiratory tract and kidneys. We report a 47-year-old man with Wegener's granulomatosis that presented as acute pancreatitis.

Work disability remains a major problem in rheumatoid arthritis in the 2000s: data from 32 countries in the QUEST-RA study.

INTRODUCTION: Work disability is a major consequence of rheumatoid arthritis (RA), associated not only with traditional disease activity variables, but also more significantly with demographic, functional, occupational, and societal variables. Recent reports suggest that the use of biologic agents offers potential for reduced work disability rates, but the conclusions are based on surrogate disease activity measures derived from studies primarily from Western countries. METHODS: The Quantitative Standard Monitoring of Patients with RA (QUEST-RA) multinational database of 8,039 patients in 86 sites in 32 countries, 16 with high gross domestic product (GDP) (>24K US dollars (USD) per capita) and 16 low-GDP countries (<11K USD), was analyzed for work and disability status at onset and over the course of RA and clinical status of patients who continued working or had stopped working in high-GDP versus low-GDP countries according to all RA Core Data Set measures. Associations of work disability status with RA Core Data Set variables and indices were analyzed using descriptive statistics and regression analyses. RESULTS: At the time of first symptoms, 86% of men (range 57%-100% among countries) and 64% (19%-87%) of women <65 years were working. More than one third (37%) of these patients reported subsequent work disability because of RA. Among 1,756 patients whose symptoms had begun during the 2000s, the probabilities of continuing to work were 80% (95% confidence interval (CI) 78%-82%) at 2 years and 68% (95% CI 65%-71%) at 5 years, with similar patterns in high-GDP and low-GDP countries. Patients who continued working versus stopped working had significantly better clinical status for all clinical status measures and patient self-report scores, with similar patterns in high-GDP and low-GDP countries. However, patients who had stopped working in high-GDP countries had better clinical status than patients who continued working in low-GDP countries. The most significant identifier of work disability in all subgroups was Health Assessment Questionnaire (HAQ) functional disability score. CONCLUSIONS: Work disability rates remain high among people with RA during this millennium. In low-GDP countries, people remain working with high levels of disability and disease activity. Cultural and economic differences between societies affect work disability as an outcome measure for RA.
