Juvenile systemic sclerosis: experience from a tertiary care center from India.
|
| Abstract |
Juvenile systemic sclerosis (JSSc) is a rare disorder with paucity of information on its treatment and longterm outcome. Herein, we are sharing our experience with this rare entity. Case records of children, diagnosed to have systemic sclerosis attending Pediatric Rheumatology Clinic at All India Institute of Medical Sciences, New Delhi from January 1998 to June 2016 were reviewed. The demographic, clinical, laboratory, treatment and outcome details were recorded. Disease outcome was classified arbitrarily as controlled, partly controlled or non-responsive/progressive based on: (A) ability to perform activities of daily life (ADL) and (B) presence or absence of musculoskeletal symptoms, skin changes (ulceration/progressive digital pitting/gangrene), and visceral organ involvement (dyspahgia, cardiopulmonary symptoms). Controlled: ability to perform ADL and absence of B features for at least 6 months. Partly controlled: inability to perform ADL or any of the B features. Non-responsive/progressive disease: presence of both A and any of B features. Thirty-two children (21, girls) diagnosed as systemic sclerosis for whom follow-up of more than 6 months was available were included for this retrospective analysis. Mean (SD) age at presentation was 112.79 (30.05) months, while the median (IQR) delay in diagnosis was 28.5 (9-47.25) months. Of the 32 children 17 (53.12%) had diffuse systemic sclerosis (dSSc), 5 (15.62%) had limited systemic sclerosis (lSSc) and 10 (31.25%) had sclerosis with overlap syndrome. The common clinical features apart from sclerosis/induration proximal to metacarpophalangeal joint were Raynauds phenomenon (n = 22, 68.7%), skin rash (n = 20, 62%), arthritis or arthralgia (n = 16, 50%), and muscular weakness (n = 10, 31.2%). Among those for whom data regarding investigations were available; ANA was positive in 50% (12/24), whereas Anti Scl70 was positive in one out three cases. Treatment regimen included naproxen, methotrexate, calcium channel blockers with or without steroids. HCQ was added in children with skin rash or in children with partial control. Median (IQR) follow-up period was 19.75 (12-31.75) months. With the above treatment protocol, 19 (59.3%) children achieved disease control on treatment, 8 (26.6%) had partial control while 5 (16.6%) showed no response or progressive disease. Esophageal dysmotility and intertitial lung disease (ILD) were documented in three children each. Complication (cataract and herpes zoster) related to immunosuppressive therapy were observed in two children. There was no mortality during the study period. Juvenile Sclerosis though rare is associated with significant morbidities and lacks a curative treatment but a reasonable quality of life to perform daily activities can be achieved using methotrexate and steroid-based immuosuppressive therapy.
