Impact of rituximab on IgG and IgM levels in patients with autoimmune bullous diseases: a cohort study.
Article in Archives of dermatological research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Rituximab (RTX) causes hypogammaglobulinemia in a variety of autoimmune diseases. However, the exact incidence and clinical significance in patients with autoimmune bullous diseases (AIBD) remain undetermined. In this cohort study, we enrolled patients with AIBD treated with RTX at a tertiary dermatology center between 2019 and 2021. Serum IgG and IgM levels, cumulative RTX dosage, and other factors were measured at baseline and during a follow-up visit. We used multivariate linear regression to assess the effect of RTX on immunoglobulin levels over time, adjusting for factors such as cumulative RTX dose, time since last infusion, and steroid use. Hypogammaglobulinemia was defined as IgG < 600 mg/dL and IgM < 40 mg/dL. Logistic regression was employed to evaluate adjusted risk factors for developing hypogammaglobulinemia. Age at first infusion was negatively correlated with both IgG (p < 0.0001) and IgM levels (p = 0.002). Total cumulative RTX dosage was negatively associated with IgM levels (p < 0.001). Daily steroid dosage was positively correlated with IgM levels (p = 0.023). Mycophenolate mofetil was associated with lower IgG levels (p = 0.029). Daily steroid dosage was found to be associated with a lower risk of hypo-IgM development (p = 0.0497). No serious infusion-related adverse effects or mortality were observed. There were four cases of infection with no association with cumulative RTX dosage (p = 0.299). Our study shows an association between RTX and lower serum IgM levels in patients with AIBD, highlighting the need to assess serum immunoglobulin levels before RTX therapy to optimize its use and minimize adverse effects.
