Four hundred (400) cases of TB (2005 -2014) are enrolled. All possible Data are collected.The prevalence of severe cases of TB was 9 % (36 patients): Acute respiratory failure (13 patients),disseminated TB with neurological and miliary forms (13 patients)and death issue (10 patients).These patients were older(46y vs 35;p<0.05),smoker with a higher tobacco consumption(36PA vs 23PA ),malnourished (BMI :16 vs 20),diabetic (13% vs 5.6%;p=0.043),living in rural area (30% vs 11%),illiterate (43% vs 30%), with no BCG vaccine (25% vs 13%;p=0.032) and acute onset of the disease (52% vs 16%;p<0.05).In this group, patients consulted earlier (30 days vs 94 days;p=0.025) with more extrapulmonary symptoms (32% vs 12%;p<0.05),biological abnormalities(anemia: 62% vs 45 and hepatic cytolysis: 5.5% vs 1.2%)and extended radiological lesions(53% vs 27%;p=0.034).There was no difference in confirmation delay and treatment.However, more side effects and complications were observed in severe group: 46% vs 32% and 24% vs 12% respectively. Rapid death was recorded within 10 patients due to respiratory failure (n=7) and fatal hemoptysis (n=3). In survival patients, radiological squeals were frequent 69% vs 32%(p=0.012).Our study shows that TB as a curable disease still can be severe and fatal.To prevent this clinical form, efforts have to be done to detect exposing risk factors. %U
