    Abstract:
    To study the prevalence of connective tissue disorders and identify the epidemiological profile of the population from the northern and northeastern regions of Brazil. All patients admitted to the general medical ward at Getulio Vargas Hospital were screened through history and physical examination for the existence of known, suspected or possible connective tissue disorder. A total of 120 patients were enrolled in the study - 61 (50.8%) with systemic lupus erythematosus (SLE), 41 (34.2%) with rheumatoid arthritis (RA), 16 (13.3%) with systemic sclerosis (SS), one (0.8%) with mixed connective tissue disease (MCTD) and one (0.8%) with polymyositis (PM). Women accounted for (104) 86.7% of the participants and (83) 70.9% were non-Caucasians. The mean age was 36.8 years. Alopecia was the most frequent symptom (55/46.6%), followed by other cutaneous lesions (50/42.4%), dyspnea (47/39.8%) and chest pain (39/33.0%). The most frequent rheumatologic disorder encountered in our hospital-based study population was systemic lupus erythematosus, which is contrary to findings of the majority of studies performed in this country.
