Objective To estimate the incidence of serious infections in patients with HIV infection and autoimmune disease who were treated tumor necrosis factor (TNF) inhibitors, to compare these rates by stratified viral load levels. Methods Using a unified search strategy, 4 centers identified HIV‐infected exposed TNF inhibitors. Patient characteristics data assessed via chart review all ≥18 years old received inhibitor therapy after diagnosis, between January 1999 March 2015. Results We studied 23...

Background. The prevalence of elevated blood lead levels (EBLLs) has decreased nationally, creating challenges in identifying children at risk. Methods. In a community known to have hazards, we screened with field-administered capillary test and asked parents complete questionnaire about risk factors. Results. Of the 77 child-parent pairs parental questionnaire, 4 had finger stick ≥10 µg/dL. these, one child confirmatory venous level >10 µg/dL (1.3%; 95% CI = 0.0%-4.7%), which is near US...

Background: AVID200 is a novel, potent TGF-beta receptor ectodomain-based trap designed to selectively neutralize 1 and 3. These two isoforms have been implicated as central mediators of the pathogenesis systemic sclerosis (SSc). avoids inhibition 2, isoform that supports normal cardiac function hematopoiesis. Objectives: This first-in-human study (AVID200-01; NCT03831438 ) Phase 1, open label, multicenter, cohort dose-escalation trial evaluate safety, tolerability, pharmacokinetic (PK)...

Introduction Crystalline arthritis (CA), characterized by acute joint pain and erythema secondary to calcium pyrophosphate deposition (CPPD, or pseudogout) monosodium urate crystals (gout), is a potentially underreported complication following allogeneic hematopoietic cell transplant (alloHCT). Graft-versus-host disease prophylaxis with calcineurin inhibitors (CNIs) causes hypomagnesemia hyperuricemia, resulting in CA. CA related tacrolimus has yet be alloHCT. Case report We retrospectively...
