Abstract

OBJECTIVE:

To document the effectiveness, including the longterm effect, of a course of intravenous (IV) pulses of methylprednisolone (MP) and cyclophosphamide (CYC) in patients with scleroderma (SSc) who had evidence of lung inflammation on high resolution computer tomographic (HRCT) scan of the chest.

METHODS:

Fourteen consecutive patients with SSc and lung involvement were treated with 6 pulses of IV MP (10 mg/kg) and IV CYC (15 mg/kg) given at 3-4 weekly intervals. HRCT scans and lung function tests were performed at baseline and after the 6th pulse. Further lung function tests were repeated at 12 months and annually thereafter.

RESULTS:

Modified Rodnan skin scores improved significantly by 35% from a median baseline score of 17 (IQR 14-26.5) to a posttreatment score of 13 (IQR 10.5-18.5; p = 0.0058). HRCT scan scores improved significantly (p = 0.04). Twelve of 13 patients experienced either improvement or stabilization of the HRCT score. Median DLCO and lung volumes remained stable during the first 12 months. After a median followup of 26 months (IQR 19-43), 67% of patients experienced deterioration in DLCO. Median deterioration was 23% (IQR 44-0.6), with the median rate of deterioration of the predicted value of the DLCO/month being 0.87% (IQR 1.24-0.02). The treatment was safe and well tolerated.

CONCLUSION:

This IV regimen stabilized lung disease in patients with SSc. When treatment was stopped, or reduced in intensity, a deterioration in lung function occurred in the majority of patients. Rate of deterioration of DLCO may be a useful marker for determining the intensity of treatment. These findings have implications for treating lung disease and designing clinical trials in patients with SSc.
