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.

Objective.To describe the evolution of the pulmonary function in patients with interstitial lung disease (ILD) who are positive for at least 1 of the antisynthetase antibodies (ASAB) after medical treatment, and to compare whether the evolution of pulmonary function is associated with the type of ASAB.Methods.Patients with ILD and positive for at least 1 of the ASAB (anti-Jo1, anti-PL7, anti-PL12, anti-EJ, or anti-OJ) were included. The clinical evolution, time until death or censoring, and improvement of lung disease were registered.Results.The study included 118 patients. Most of the patients had a high extent of ground glass opacities in high-resolution computed tomography (HRCT) and low extent of fibrosis. In the final evaluation of pulmonary function (median 749.5 days of followup), 67% of the patients had lung disease improvement. The improvement occurred within the first 6 months after initiating medical treatment; thereafter, pulmonary function remained stable in most of the patients. A decrease of the extent of ground glass opacities was demonstrated in HRCT at followup in those patients with pulmonary improvement. No differences were observed in the percentage of patients who achieved improvement between the ASAB groups, or in survival.Conclusion.Improvement of pulmonary function was observed in 67% of the patients. Improvement was observed in all ASAB groups and occurred within 6 months after initiating medical treatment.
Tap water in a city like Boston, which has old houses containing lead plumbing, is known to be a significant source of potential lead exposure. Bone lead levels integrate exposure over many years, and in vivo bone lead measurements have recently become possible with the advent of K x-ray fluorescence instruments. Thus we examined the relationship between first morning tap-water lead levels measured in homes in the 1970s and levels of lead in bone measured in the 1990s among middle-aged to elderly men who lived in those homes. We studied 129 participants in the Normative Aging Study who had lead measured in their homes' tap water in 1976 and 1977 by graphite furnace-atomic absorption spectrophotometry. From 1991 to 1995, the same subjects had blood lead levels measured by graphite furnace-atomic absorption spectroscopy and tibia and patella bone lead levels measured by K x-ray fluorescence. We ran multivariate linear regression models predicting bone lead levels that adjusted for factors which had previously been linked with this outcome in the Normative Aging Study (age, pack-years of smoking, and educational level). Among subjects who lived in houses with > or = 50 micrograms lead/liter of first morning tap water representing water that had been standing overnight in the plumbing in 1976 and 1977, those who reported medium or high levels of tap-water ingestion (> or = 1 glass/day) had progressively higher patella lead levels than did those with low levels of ingestion (< 1 glass/day). No such relationship was found among subjects who lived in houses with < 50 micrograms lead/liter of first morning tap water in 1976 and 1977. We conclude that ingestion of lead-contaminated tap water is an important predictor of elevated bone lead levels later in life.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
