PEREZ CAMPOS, Dionisio et al. Expression of interstitial pneumopathy in Cuban patients with systemic sclerosis . Rev cubana med [online]. 2008, vol.47, n.2. ISSN 0034-7523.

Interstitial pneumopathy (IP) usually appears in patients with systemic sclerosis (SS) and causes significant morbidity and mortality. A descriptive and prospective study was conducted among 46 patients that fulfilled the criteria of the American Rheumatology College to identify the forms of expression and detection of IP. Percentages were estimated, and the univariable analysis for centralization and dispersion measurements and the chi square tests (X2) of statistical significance were used. A mean age of 50.4 years old was found. A prevalence of females (88 %) and of white individuals (66 %) was observed. 20 patients (43.4%) had interstitial pneumopathy, whereas 100 % of the cases presented effort dyspnea, which was statistically significant (p=0.02). The respiratory function was affected in 75 % of the sick. According to high resolution computerized tomography of the lung, 50 % had ground glass pattern and 50 % honeycomb pattern, 66 % of the patients with IP had active bronchoalveolar lavage and of them, 88 % corresponded to those with ground glass pattern. It was concluded that interstitial pneumopathy was expressed in a high percentage of patients. Effort dyspnea was the most frequent symptom and the restrictive pattern predominated. CAT and the cytological study of bronchoalveolar lavage were key tools for the early diagnosis of IP.
