Introduction:

Epidemiological studies on sarcoidosis in Colombia are scarce, and although recent reports from the north of the country have been published, clinical-epidemiological associations are not clear. Our aim was to characterize patients with sarcoidosis diagnosed at Fundación Valle del Lili in Cali, Colombia.

Methods:

A retrospective study of a series of sarcoidosis cases was conducted between 2011 and 2019. Demographic, clinical, laboratory, imaging, histopathological, and treatment variables were analyzed.

Results:

A total of 34 patients with a diagnosis of sarcoidosis were found. The majority were women (n = 25; 73%), and the mean age was 50 years. The main symptoms of onset were erythema nodosum (n = 11; 33%), arthritis (n = 10; 30%), and cough (n = 9; 27%). In 64% of the cases, there was pulmonary involvement, with pulmonary nodules, mediastinal adenopathy, and interstitial lung disease found in 54%, 50%, and 36% of cases, respectively. In 85% of cases, there were extrapulmonary manifestations, mainly cutaneous (50%). Angiotensin-converting enzyme (ACE) was elevated in 62% of the cases in which it was measured (n = 16; 47%). During the diagnostic process, 23 biopsies were performed, of which 95% showed granulomas with noncaseating necrosis. Most of the patients (76%) were controlled with prednisolone, at an average dose of 20 mg (7.5-50 mg) per day.

Conclusions:

Sarcoidosis was more frequent in women and mestizos, and it presented earlier in men. Elevated ACE was not associated with extrapulmonary involvement. Calcium-phosphorus profile and antinuclear antibodies were not useful to establish the diagnosis.
