Background: Oral corticosteroids (OCS) and intravenous methylprednisolone (IVMP) remain the backbone of therapeutic intervention for juvenile dermatomyositis (JDM).

Methods:We analyzed anthropometric (height, weight, and BMI) data, including percentile measures from growth charts, along with resolution of functional disability, as measured by the modified Rankin scale (MRS), to determine differences in effects between OCS or IVMP treatment.

Results:Over a 15-year period, 25 JDM patients had complete or near-complete resolution of symptoms and returned to baseline function based on MRS. Within groups, increases in weight and BMI percentiles were only significant in the OCS group (p = 0.009 and 0.011, respectively). Between groups, pretreatment height (p = 0.031), and posttreatment weight (p = 0.048) and BMI (p = 0.048) were significantly different. Percentile changes post- and pretreatment compared to 50th percentile weight for given height and age, along with changes based on a 50th percentile agematched individual were likely to be lower for the IVMP group as compared to the OCS group (p = 0.008 and 0.028, respectively).

ConclusionBoth OCS and IVMP resolved symptomology, but the results suggest that IVMP had a less significant negative impact on growth measures.
