Prevalence and predictors of sustained remission/low disease activity after discontinuation of induction or maintenance treatment with tumor necrosis factor inhibitors in rheumatoid arthritis: a systematic and scoping review.

BACKGROUND: To determine the prevalence of sustained remission/low disease activity (LDA) in patients with rheumatoid arthritis (RA) after discontinuation of tumor necrosis factor inhibitors (TNFi), separately in induction treatment and maintenance treatment studies, and to identify predictors of successful discontinuation. METHODS: We performed a systematic literature review of studies published from 2005 to May 2022 that reported outcomes after TNFi discontinuation among patients in remission/LDA. We computed prevalences of successful discontinuation by induction or maintenance treatment, remission criterion, and follow-up time. We performed a scoping review of predictors of successful discontinuation. RESULTS: Twenty-two induction-withdrawal studies were identified. In pooled analyses, 58% (95% confidence interval (CI) 45, 70) had DAS28 < 3.2 (9 studies), 52% (95% CI 35, 69) had DAS28 < 2.6 (9 studies), and 40% (95% CI 18, 64) had SDAI ≤ 3.3 (4 studies) at 37-52 weeks after discontinuation. Among patients who continued TNFi, 62 to 85% maintained remission. Twenty-two studies of maintenance treatment discontinuation were also identified. At 37-52 weeks after TNFi discontinuation, 48% (95% CI 38, 59) had DAS28 < 3.2 (10 studies), and 47% (95% CI 33, 62) had DAS28 < 2.6 (6 studies). Heterogeneity among studies was high. Data on predictors in induction-withdrawal studies were limited. In both treatment scenarios, longer duration of RA was most consistently associated with less successful discontinuation. CONCLUSIONS: Approximately one-half of patients with RA remain in remission/LDA for up to 1 year after TNFi discontinuation, with slightly higher proportions in induction-withdrawal settings than with maintenance treatment discontinuation.

Cutaneous Chronic Graft Versus Host Disease in a Symmetric Distribution.

Graft-versus-host disease (GVHD) is a common complication following patients who have undergone allogenic hematopoietic stem cell transplantation (allo-HSCT). While GVHD has been previously sub-categorized through a temporal relationship upon transplantation, revisions from the National Institutes of Health have modified the diagnosis criteria to be more involved with specific signs and symptoms. Chronic classifications of GVHD include non-sclerotic and sclerotic forms, and the sclerotic form can be further classified based on morphologies such as lichen-sclerosis-like, sclerodermoid or morphea-like plaques. Generalized morphea can have similar histopathological findings but in order to be diagnosed, certain diagnostic criteria must be met. Herein, we report a patient with linear and inflammatory morphea morphology of chronic GVHD, which presents symmetrically on both lower extremities.
