Patients with rheumatic and musculoskeletal (RMD) diseases may be at higher risks for COVID-19 infection. Data on the safety of the adenoviral vector-borne ChAdOx1 nCoV-19 and the heat-inactivated BBV152 Vaccines in this group are limited. 724 patients with RMD who had received at least one dose of either the ChAdOx1 or the BBV152 were audited to find out post-vaccination adverse effect (AE) or disease flares. The AE rates in patients with autoimmune rheumatic disease (AIRD) were compared with those with non-AIRD RMDs. The mean age of the cohort was 59.9 (± 10.43) years with a female ( n = 581; 80.24%) majority. 523 (70.8%) had AIRD. The ChAdOx1 and the BBV152 vaccines were received by 624 (86.18%) and 77 (10.63%), respectively. 23 (3.17%) were unaware of which vaccine they had received. 238 (32.87%) of patients had at least one comorbidity. 436 (60.22%) participants [306 (59.64%) of those with AIRD and 130 (61.61%) with other RMDs] had at least one adverse effect (AE). Four patients reported flare of arthritis that resolved within 5 days. No patient had any severe AE or required hospitalization. All AEs were self-limiting. Both the ChAdOx1 and the BBV152 vaccines appear safe in RMDs. AEs do not differ between patients with AIRD or non-AIRD. This information can help negate vaccine hesitancy amongst all stakeholders.

To evaluate the performance of TrueNAT (RT Micro PCR device) assay in comparison with GeneXpert on sputum samples from pulmonary cases of tuberculosis. 274 samples were processed to detect MTB by ZN smear examination, MGIT culture and molecular methods that included RT-PCR (ABI 7500 & TrueNAT) and GeneXpert for case detection of TB. The overall performance of the test with MGIT(Mycobacterium Growth Indicator Tube) culture as gold standard, sensitivity of smear, RT PCR/TrueNAT and Genexpert was 61.5% (CI:53.3-69.3%), 94.7% (CI:89.8-97.6%) & 96.0% (CI: 91.5-98.5%), respectively. Amongst the S+ (108) samples, RT-PCR/TrueNAT and GeneXpert showed a sensitivity of 99% (CI:94.9%-99.8%) and 100% (98.6%-100.0%), respectively. High concordance was observed between GeneXpert and TrueNAT for case detection of TB. The GeneXpert MTB/RIF test was independent on the user's skills. It has a short turn-around time and simultaneously detects RIF resistance with M. tuberculosis in less than 3h. The TrueNAT MTB has good sensitivity and specificity in case detection with hands on time of less than 3h as well as fits the requirements in resourcelimited health care settings. Larger, multi-site studies are required to obtain better estimates of the performance of TrueNAT MTB.

Introduction/Aims We studied COVID‐19 vaccination‐related adverse events (ADEs) 7‐days post‐vaccination in patients with idiopathic inflammatory myopathies (IIMs) and other systemic autoimmune and inflammatory disorders (SAIDs). Methods 7‐day vaccine ADEs were collected in an international patient self‐reported e‐survey. Descriptive statistics and multivariable regression were performed. Results 10,900 respondents [1227 IIMs; 4640 SAIDs; 5033 healthy controls (HCs), median age 42 (IQR 30‐55) years, 74% female, 45% Caucasian, 69% completely vaccinated] were analysed. 76.3% IIMs patients reported minor and 4.6% major ADEs. Patients with active IIMs reported more frequent major [OR 2.7 (1.04‐7.3)] and minor [OR 1.5 (1.1‐2.2)] ADEs than inactive IIMs. Rashes were more frequent in IIMs [OR‐2.3(1.2‐4.2)] than HCs. ADEs were not impacted by steroid dose, although hydroxychloroquine and intravenous/subcutaneous immunoglobulins were associated with a higher risk of minor ADEs [OR 1.9 (1.1‐3.3), OR 2.2 (1.1‐4.3)]. Overall, ADEs were less frequent in inclusion body myositis (IBM) and BNT162b2 (Pfizer) vaccine recipients Discussion 7‐day post‐vaccination ADEs were comparable in patients with IIMs, SAIDs, and HCs, except for a higher risk of rashes in IIMs. Patients with DM, active disease may be at higher risk, and IBM patients at lower risk of specific ADEs. Overall, the benefit of preventing severe COVID‐19 through vaccination likely outweighs the risk of vaccine‐related ADEs Our results may inform future guidelines regarding COVID‐19 vaccination in patients with SAIDs, and specifically in IIMs. Studies to evaluate long‐term outcomes and disease flares are needed to shed more light on developing future COVID‐19 vaccination guidelines.
