Implementing a Virtual Flipped Classroom in a Rheumatology Fellowship Program.

OBJECTIVE: Active learning opportunities within graduate medical education may be underused. We aimed to assess whether active learning strategies increase after implementing a faculty development workshop and transitioning rheumatology fellowship didactics to a virtual flipped classroom. METHODS: We measured baseline faculty use of active learning strategies during lectures within the Introductory Rheumatology Curriculum by calculating an "active learning score" from a cognitive learning theory assessment tool. We held a faculty development workshop demonstrating active teaching strategies and encouraged using a flipped classroom for fellowship didactics. Because of the COVID-19 pandemic, the strategies were discussed in a virtual classroom setting where the intervention phase would occur. We compared active learning scores before and after the intervention for lectures within the Introductory Rheumatology Curriculum. The primary outcome was the change in active teaching scores preintervention versus postintervention. RESULTS: Active learning scores increased in 14 of the 16 lectures, with a mean score increase of 4.7 of 24 points (95% confidence interval 2.3-7.2). Paired t-test analyses comparing active learning scores preintervention and postintervention for each lecture confirmed that results were highly statistically significant (P < 0.001). Despite faculty hesitancy to teach within a virtual environment, faculty satisfaction remained high postintervention. CONCLUSION: A virtual flipped classroom increased the use of active learning strategies within the Introductory Rheumatology Curriculum. Faculty satisfaction remained high despite modest increases in time spent updating their presentations. Fellows and faculty reported a largely positive experience within the virtual classroom.

Using FibroScan to Assess for the Development of Liver Fibrosis in Patients With Arthritis on Methotrexate: A Single-center Experience.

OBJECTIVE: Methotrexate (MTX) is often the primary medication to treat various rheumatic diseases (RDs) because of its low cost and its demonstrated efficacy in controlling disease activity. However, a concern has been the potential for hepatic fibrosis associated with long-term MTX usage. This study investigated the association between cumulative MTX intake and development of liver fibrosis by utilizing noninvasive transient elastography (FibroScan). METHODS: All patients with inflammatory arthritis treated with MTX were offered screening with FibroScan. A certified technician measured liver stiffness after patients adhered to a fast. Relevant clinical information was obtained by patient survey and medical records review. The population was divided into quartiles based on participants' cumulative dosage of MTX. RESULTS: Five hundred twenty patients with RD were included in this study. The prevalence of stages F3 or F4 liver fibrosis was 13.3% in the control group and 12.7% in the entire sample. Compared with subgroup 1 (control with cumulative MTX exposure of ≤ 499 mg), MTX subgroups 2 to 4 were not significantly correlated with higher FibroScan scores (P = 0.82, 0.59, and 0.18, respectively). In multivariable linear regression analysis, statistically significant factors for liver stiffness were BMI, waist circumference, male sex, and age. CONCLUSION: No significant correlation between the cumulative MTX dosage and liver stiffness, even at high MTX doses, was observed. The analyses showed significant correlations between the FibroScan score and BMI. These findings were reassuring in that current rheumatology practice appears to be safe and effective in screening for liver fibrosis in patients on long-term low-dose MTX therapy.

Engaging trainees within the virtual classroom: Teaching strategies for rheumatologists in a pandemic.

Social distancing during the COVID-19 pandemic has led to unprecedented challenges in medical education, including for rheumatology training programs. Many programs have adapted by transitioning educational curricula into virtual classrooms. Herein, we review strategies to optimize learning within the virtual classroom. We introduce the flipped virtual classroom as a framework for facilitating higher-order thinking and improving long-term learning. We provide recommendations to maximize interactions between learners, elevate group discussions, and encourage problem solving. Once implemented, these techniques can lead to more productive teaching and learning experiences while maintaining a sense of community for rheumatology training programs.

Immunogenicity of SARS-CoV-2 vaccination in rituximab-treated patients: Effect of timing and immunologic parameters.

Rituximab (RTX), an important therapeutic option for patients with rheumatic diseases, has been shown to reduce immune responses to various vaccines. We asked whether following SARS-CoV-2 vaccination, response rates in RTX treated patients are reduced and whether specific patient characteristics influence the responses. We recruited patients on chronic RTX therapy undergoing anti-SARS-CoV2 vaccination and measured the post-vaccination anti-spike IgG antibody levels. The median time from pre-vaccination RTX infusion to vaccination and from vaccination to the post-vaccination RTX infusion was 20.5 weeks and 7.2 weeks respectively. Only 36.5% of patients developed measurable titers of IgG anti-SARS-CoV-2 spike antibody after vaccination. Hypogammaglobulinemia (IgG and/or IgM) but not timing of vaccination, B cell numbers, or concomitant immune suppressive medications, correlated with sero-negativity (p = 0.004). Our results underscore the fact that even after B cell reconstitution, RTX induced chronic hypogammaglobulinemia significantly impairs the ability of the immune system to respond to SARS-CoV-2 vaccination.

Rituximab-associated hypogammaglobulinemia in autoimmune rheumatic diseases: a single-center retrospective cohort study.

B-cell targeted therapies, such as rituximab (RTX), are used widely in autoimmune rheumatic diseases (AIRD). RTX can cause hypogammaglobulinemia and predispose patients to infections. Herein, we asked whether the underlying diagnosis influences the risk for hypogammaglobulinemia in patients treated with RTX. All patients who received RTX infusions and carried a diagnosis of rheumatoid arthritis (RA), ANCA-associated vasculitis (AAV), or connective tissue disease (CTD) were included in this single-center retrospective cohort study. We used STATA® for analysis: Chi-square test was used for comparing categorical variables. Based on distribution, continuous variables were compared using the t test/ANOVA or the Wilcoxon/Kruskal-Wallis tests. Of the 163 patients who received RTX for an AIRD, 60 with pre- and post- RTX immunoglobulins were analyzed. A higher incidence of post-treatment hypogammaglobulinemia was seen in AAV (45%) compared to RA (22%) and CTD (9.1%) groups (p = 0.03). Glucocorticoid exposure of 10 mg or more was identified as a significant risk factor for hypogammaglobulinemia. Finally, we observed a higher number of clinically significant infections per person in the AAV group than in the RA and CTD groups. We observed an increased incidence of hypogammaglobulinemia in the RTX-treated AAV group, with almost half of patients developing post-RTX hypogammaglobulinemia. The rate of infections per person was highest in the AAV group. Screening immunoglobulins were not consistently measured pre- and post-RTX. Results highlight a need for increased awareness of the role of immunoglobulin measurement before maintenance doses of RTX, especially in patients with AAV and steroid exposure.
