Tuberculosis in southern Morocco: Retrospective analysis from 2006 to 2012

Abstract

INTRODUCTION: Tuberculosis, a global major concern, causes millions of deaths annually despite WHO strategies. A persistent gap in detection and treatment facilitates rapid spread in high-burden countries. AIMS: Analyze the clinical-epidemiological profile of tuberculosis patients in Laayoune and Tarfaya, Morocco, emphasizing risk factors and evolution of the tuberculosis Methods: Retrospective analysis of 1332 tuberculosis cases at the Respiratory Diseases Diagnosis and Treatment Center in Laayoune (2006-2012). Variables with P < 0.10 in univariate analysis were included in multivariate analysis using multiple logistic regression to define the risk factors for tuberculosis, expressed as odds ratios (OR) with a 95% confidence interval (CI). RESULTS: The analysis revealed a pulmonary predominance (≈61%), with pleural (41.3%) and lymph node (31.5%) tuberculosis prevalent among extrapulmonary cases. Among 515 extrapulmonary tuberculosis cases, intestinal tuberculosis (14 cases) showed the highest mortality rate at 14.29%. The 15 to 64 age groups had a significantly higher risk of contracting pulmonary tuberculosis to children, and the 65 and over age group also had the highest risk of developing pulmonary tuberculosis (aOR=5.83 [2.43, 14.00]). Other risk factors included rural origin, personal history of tuberculosis, and smoking, all significantly associated with pulmonary tuberculosis (aOR=2.40 [1.001, 5.76]; aOR=2.00 [1.11, 3.61]; aOR=2.38 [1.40, 4.06]). Conversely, female gender was a protective factor (aOR=0.53 [0.40, 0.70]). Regarding recovery and loss to follow-up rates, they were higher in those with pulmonary tuberculosis (39.0% vs 2.1%; aOR=33.41 [17, 66.52]; 16.9% vs 10.3%; aOR=1.57 [1.02, 2.41], respectively). CONCLUSION: Holistic initiatives across various sectors will be essential to eliminate tuberculosis by 2030.
