Background/Purpose: Juvenile dermatomyositis (JDM) is the most common clinical pediatric idiopathic inflammatory myopathy and it may severely compromise the quality of life of affected patients. Early adequate immunosuppressive treatment can improve the quality of life in JDM as in other rheumatic diseases like juvenile idiopathic arthritis (JIA).1
Objective: To evaluate the HRQoL change over time in children with new-onset JDM patients enrolled in the PRINTO trial2.
Methods: In the PRINTO JDM trial, children aged 18 years old or younger with newly diagnosed and untreated probable or definite JDM were enrolled. All patients received three daily pulses of intravenous methylprednisolone at onset, and then they were randomized to one of the following three different treatment groups: prednisone (PDN), prednisone plus ciclosporin (PDN+CSA) and prednisone plus methotrexate (PDN+MTX).
In our study, we considered patients who had a complete HRQoL assessment at onset through the Child Health Questionnaire (CHQ). We compared quality of life among the responders (PRINTO20-50-70) belonging to the three treatment groups, and between responder and not responder patients. Moreover we compared the affected patients to healthy children.
Results: Out of a total of 139 patients enrolled in the PRINTO JDM trial, 129 (92.8%) were retained for the analysis (41.9% males and 58.1% females; median age 7.4 years). At baseline, patients with JDM showed poorer scores in quality of life (PhS = 15.6 and PsS=40.0) than healthy children. In particular, “Physical Summary score” (PhS) turned out to be significantly lower than 2 standard deviations with respect to the mean value of the healthy children with no difference among the 3 treatment groups (PDN, PDN+MTX, PDN+CSA). Less compromised scores were observed for the PsychoSocial summary Scale, with values between 1 and 2 standard deviations below the mean values of healthy children. We found similar values between «responder 20» and «not responders». A statistically significant improvement was observed after 6 months of treatment both in the PhS and in the PsS subscales (P<0.0001) irrespective of the treatment group, and in all items of the CHQ with the exception of the GBE (Global behavior parameter). A significant improvement over time was observed regardless of the treatment group and the level of response (PRINTO 20, 50, 70). “Responder” patients showed PhS values significantly higher than “not responder”; on the contrary, PsS values did not reveal a significant difference between “responders” and “not responders”, despite an improvement over time.
Conclusion: Children with new-onset JDM, treated with PDN alone or in combination with other therapies, showed a significant improvement in quality of life during a two-year follow-up. According to the “PRINTO 20-50-70” criteria, “responder” patients showed a statistically significant improvement in the PhS score compared to the “not responders”.
