Epidemiological profile among pulmonary and extrapulmonary tuberculosis patients in Laayoune, Morocco

INTRODUCTION: despite major strides in the prevention, diagnosis and management of tuberculosis, the disease continues to be one of the most pressing global health problems, particularly in developing countries. The purpose of the present study was to describe the epidemiological profile among tuberculosis patients in Laayoune, Morocco. METHODS: a retrospective study was conducted among tuberculosis patients (having extrapulmonary tuberculosis and pulmonary tuberculosis), registered in the diagnosis of tuberculosis and respiratory diseases reference center of Laayoune, between January 2017 and May 2018. Demographic characteristics, clinical presentation of TB and apparent risk factors of the disease were obtained from the medical case records of all patients. RESULTS: during the study period, a total of 211 patients (125 males and 86 females) with tuberculosis were enrolled. The majority of cases (93.40%) were newly diagnosed and the segment with the pulmonary tuberculosis was 63.50%. The highest disease burden was found in the ≥15 year age group (92.40%; p=0.022). Men were more frequently affected by pulmonary tuberculosis (70.90%), while extrapulmonary tuberculosis was more commonly detected in women (61%) (p<0.0001). The most common sites of extrapulmonary disease were lymphatic (32.47%), pleural (16.88%) and spinal tuberculosis (15.58%). HIV infection and smoking seem to be the most important risk factors that affect host defense against TB infection. CONCLUSION: the results obtained in tuberculosis patients in Laayoune, Morocco, showed that active tuberculosis was associated with risk factors such as sex, age and smoking.
