Background Scleroderma is an autoimmune disease characterized mainly by skin manifestations and various visceral organs involvement especially lungs. Lung involvement is the leading cause of mortality in this patients.Various studies have demonstrated efficacy of cyclophosphamide (CYC) and mycophenolate mofetil (MMF) in SSc-ILD but no head to head comparative data is available till date.

Objectives To compare efficacy of CYC & MMF in patients with SSc-ILD in terms of improvement in lung function.

Methods Patients more than 18 years of age fulfilling ACR 2012 classification criteria for Systemic sclerosis with significant ILD as defined by Forced vital capacity (FVC) ≤80 and Presence of ILD on thoracic high resolution computerized tomography were included.MMF group received upto 3gm daily and CYC group received 600mg/m2 (Max 1.2 gm) for total duration of 6 months.Monthly clinical assessment and 3 monthly lung function (spirometry-FVC) were done for 6 months.Response was evaluated as per American Thoracic Society recommendations (improvement when increase in FVC ≥10%, stabilization when change in FVC <10% and worse reduction in FVC was ≥10%).Appropriate statistical tests were applied to analyse the data.

Results 23 patients (18 female/5 male) in CYC and 44 patients (40 female/4 male) in MMF group were included with mean age of 46±10.34 years (mean disease duration of 6.04±5.96 years) and 45.54± 13.74 years (mean disease duration of 4.84±4.08 years) in respective groups.After 6 months of induction therapy,increase in mean percentage of FVC observed was 10.84±13.81% (p=0.003) in CYC and 6.07±11.92% (p=0.006) in MMF group.When the change in FVC at 6 months in both groups were compared to each other,no significance difference was found (p=0.373).

Conclusions We support the use of mycophenolate for the patients for whom CYC is contraindicated or not tolerated, given the substantial toxicities and modest benefit of CYC as alternative.A prospective multicenter controlled trial of mycophenolate in SSc-ILD patients is warranted to support the above data.
