#Anticardiolipin and other #antiphospholipid antibodies in critically ill #COVID-19 positive and negative patients

Reports of severe COVID-19 being associated with thrombosis, antiphospholipid antibodies (APLA), and antiphospholipid syndrome have yielded disparate conclusions. Studies comparing patients with COVID-19 with contemporaneous controls of similar severity are lacking. Methods 22 COVID-19+ and 20 COVID-19– patients with respiratory failure admitted to intensive care were studied longitudinally. Demographic and clinical data were obtained from the day of admission. APLA testing included anticardiolipin (aCL), anti-β2glycoprotien … Continue reading #Anticardiolipin and other #antiphospholipid antibodies in critically ill #COVID-19 positive and negative patients

#Cotrimoxazole prophylaxis prevents major infective episodes in patients with systemic #lupus erythematosus on immunosuppressants: A non-concurrent cohort study

Prophylactic trimethoprim-sulfamethoxazole (TMP-SMX) prevents pneumocystis jirovecii infection in SLE on immunosuppression. Its role in preventing other major infections in immuno suppressed SLE patients is unknown. Methods A non-concurrent cohort study was conducted on patients of SLE fulfilling SLICC and/or ACR 1997 criteria, who received tapering dose of steroid starting with ≥0.5 mg/kg/day of prednisolone or equivalent dose of deflazacort and mycophenolate mofetil ≥1 g/day (or equivalent dose … Continue reading #Cotrimoxazole prophylaxis prevents major infective episodes in patients with systemic #lupus erythematosus on immunosuppressants: A non-concurrent cohort study

#Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis

The aims of this study were to examine the longitudinal and bi-directional associations of pain and fatigue with sedentary, standing and stepping time in RA. Methods People living with RA undertook identical assessments at baseline (T1, n = 104) and 6-month follow-up (T2, n = 54). Participants completed physical measures (e.g. height, weight, BMI) and routine clinical assessments to characterize RA disease activity (DAS-28). Participants also completed questionnaires to … Continue reading #Pain and fatigue are longitudinally and bi-directionally associated with more #sedentary time and less standing time in #rheumatoid arthritis

Finger Joint #Cartilage Evaluated by Semiquantitative #Ultrasound Score in Patients With #Rheumatoid Arthritis

Joint destruction in rheumatoid arthritis (RA) includes both bone and cartilage lesions. Since joint space narrowing (JSN) is not a direct evaluation of cartilage using radiography, we aimed to examine the validity of ultrasound (US) cartilage evaluation using a semiquantitative method in patients with RA. Methods We enrolled 103 patients with RA who were in remission or showing low disease activity and 42 healthy subjects. … Continue reading Finger Joint #Cartilage Evaluated by Semiquantitative #Ultrasound Score in Patients With #Rheumatoid Arthritis

Association of Maternal #Autoimmune Disease With #Attention-Deficit/Hyperactivity Disorder in Children

Maternal autoimmune disease has been associated with increased risk of neurodevelopmental disorders in offspring, but few studies have assessed the association with attention-deficit/hyperactivity disorder (ADHD).. ..In the population-based cohort analysis, 831 718 singleton, term infants born to 831 718 mothers (mean [SD] age, 29.8 [5.6] years) were assessed. Of 12 767 infants (1.5%) who were linked to a maternal autoimmune diagnosis, 12 610 were propensity score matched to 50 440 … Continue reading Association of Maternal #Autoimmune Disease With #Attention-Deficit/Hyperactivity Disorder in Children

Anti-neutrophil properties of natural #gingerols in models of #lupus

Ginger is known to have anti-inflammatory and anti-oxidative effects, and has traditionally been used as an herbal supplement in the treatment of various chronic diseases. Here, we report anti-neutrophil properties of 6-gingerol, the most abundant bioactive compound of ginger root, in models of lupus and antiphospholipid syndrome (APS). Specifically, we demonstrate that 6-gingerol attenuates neutrophil extracellular trap (NET) release in response to lupus- and APS-relevant … Continue reading Anti-neutrophil properties of natural #gingerols in models of #lupus

Risk for Serious #Infection With Low-Dose #Glucocorticoids in Patients With #Rheumatoid Arthritis

Low-dose glucocorticoids are frequently used for the management of rheumatoid arthritis (RA) and other chronic conditions, but the safety of long-term use remains uncertain.. ..Associations between glucocorticoid dose (none, ≤5 mg/d, >5 to 10 mg/d, and >10 mg/d) and hospitalized infection were evaluated using inverse probability–weighted analyses, with 1-year cumulative incidence predicted from weighted models. Results: 247 297 observations were identified among 172 041 patients … Continue reading Risk for Serious #Infection With Low-Dose #Glucocorticoids in Patients With #Rheumatoid Arthritis

#Depression and subsequent risk for incident rheumatoid #arthritis among women

We investigated the association of depression with subsequent risk of rheumatoid arthritis (RA) by serologic phenotype.. ..Among 195,358 women, we identified 858 incident RA cases (65% seropositive) over 3,087,556 person‐years (median 17.9 years/participant). Compared to women without depression, those with depression had multivariable HRs (95%CIs) of: 1.28(1.10‐1.48) for all RA; 1.12(0.93‐1.35) for seropositive RA; and 1.63(1.27‐2.09) for seronegative RA. When analyzing components of the composite … Continue reading #Depression and subsequent risk for incident rheumatoid #arthritis among women

Association of #Cigarette Smoking With Antineutrophil Cytoplasmic Antibody–Associated #Vasculitis

Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a systemic small vessel vasculitis characterized by circulating ANCAs targeting proteinase 3 (PR3) or myeloperoxidase (MPO) and associated with excess morbidity and mortality. Myeloperoxidase-ANCA–positive AAV and PR3-ANCA–positive AAV are increasingly recognized to have differences in genetic risk, pathogenesis, and response to treatment. Risk factors for AAV, including cigarette smoking, are poorly understood.. ..Overall, 473 cases were matched with … Continue reading Association of #Cigarette Smoking With Antineutrophil Cytoplasmic Antibody–Associated #Vasculitis

Association of Serum #Folate Levels With Cardiovascular Mortality Among Adults With Rheumatoid #Arthritis

Patients with rheumatoid arthritis (RA) are at high risk for cardiovascular (CV) mortality, attributed to chronic inflammation coupled with elevated circulatory homocysteine levels. Increasing the serum folate level reduces homocysteine, but the association of serum folate concentration with CV mortality in patients with RA has not been previously examined.. A total of 683 patients with RA (mean [SE] age, 55.9 [1.0] years; 225 [30.2%] men; … Continue reading Association of Serum #Folate Levels With Cardiovascular Mortality Among Adults With Rheumatoid #Arthritis

Comparing the burdens of opportunistic #infections among patients with systemic #rheumatic diseases: a nationally representative cohort study

The IR of opportunistic infections was highest for PM/DM cases (61.3/1000 person-years, 95% confidence interval [CI] 56.6–66.2), followed by SLE cases (43.1/1000 person-years, 95% CI 41.7–44.5), SSc cases (31.6/1000 person-years, 95% CI 28.3–35.1), RA cases (25.0/1000 person-years, 95% CI 24.4–25.7), and pSS cases (24.1/1000 person-years, 95% CI 23.1–25.2). Multivariable Cox analysis revealed that, relative to SLE, PM/DM was associated with a significantly higher risk of … Continue reading Comparing the burdens of opportunistic #infections among patients with systemic #rheumatic diseases: a nationally representative cohort study
