Abstract
BACKGROUND: Management of generalized granuloma annulare (GGA) poses challenges for both patients and dermatologists. Currently, there are no established first-line therapies for GGA and the available therapeutic modalities are based on individual case reports and a few small case series. Further, there are limited publications assessing the efficacy of methotrexate in treating GGA.
OBJECTIVE: Evaluate the efficacy and adverse effects associated with methotrexate treatment of GGA.
METHODS: Descriptive retrospective case series of 11 patients with GGA receiving methotrexate.
RESULTS: 64% of patients receiving methotrexate noted improvement of their skin disease, of which 43% achieved complete clearance and 57% partial clearance. Initial dose of methotrexate ranged from 12.5-15mg weekly, administered either orally or subcutaneously. The majority of patients tolerated the treatment well. However, 18% of patients experienced the adverse effects of either GI upset or hair loss.
LIMITATIONS: This case series lacks a control group and therefore has low internal validity. The lack of a disease severity and therapy responsiveness measurement tool made quantifying disease improvement inexact.
CONCLUSION: Methotrexate can be a successful and well-tolerated treatment option for patients with generalized GA.
