[Dynamic of respiratory pathology in a service of pneumology in black Africa in the context of HIV infection from 1998 to 2007]. / Dynamique de la pathologie respiratoire dans un service de pneumologie en Afrique noire dans le contexte de l'infection à VIH de 1998 à 2007.

INTRODUCTION: The pneumology in developing countries is practiced in a singular context: population mostly younger, endemic tuberculosis, high prevalence of HIV infection and growing pollution. OBJECTIVE: The aim of this study is to present respiratory pathology evolution in hospitalization of pneumology department in black Africa. METHODOLOGY: Our study is retrospective and descriptive. We consulted the register of hospitalization activities from January 1998 to December 2007. RESULTS: The age group of 20-49 years represents 78.36% of all patients. Tuberculosis (TB) remains the first affection from 1998 to 2007 with a frequency varying between 38.2% and 45.2%. The cases of pneumonia are in regression since 2001, but cases of febrile alveolar interstitial pneumonia (FAIP) increase. The pathologies bound to tobacco addiction are rare. HIV infection is associated to TB (82.86%), to pneumonia (77.22%), to FAIP (92.23%). On 832 cases of death recorded, 46.15% of deaths are assigned to TB, 15.98% to pneumonia and 14.66% to FAIP. The global lethality of the TB and the pneumonia is respectively 20.1% and 17.6%. The one of FAIP is 32.5%. Mortality attributable to TB and pneumonia decreases progressively but the one attributable to FAIP remains important. CONCLUSION: Respiratory pathology is dominated by TB, pneumonia and FAIP. These pathologies associated to HIV infection cause a strong mortality.

[Predictive factors of lost to follow-up status during tuberculosis treatment]. / Facteurs prédictifs du statut « perdus de vue ¼ au cours du traitement de la tuberculose.

INTRODUCTION: Patients with contagious tuberculosis who are lost to follow-up risk sowing the disease among their circle of acquaintances. Moreover, a history of inadequate anti-tuberculous treatment is an important risk factor for the development of drug-resistant organisms. The purpose of this study was to identify risk factors for loss to follow-up among patients undergoing treatment for tuberculosis. METHODOLOGY: We performed a prospective cohort study among patients with contagious tuberculosis, beginning with anti-tuberculous treatment followed during six months, after initial education-information about their condition. We compared the characteristics of 152 patients lost to follow-up from tuberculosis treatment against those of 492 patients who were not lost to follow-up. RESULTS: Independent factors associated with a reduction in the risk of being lost to follow-up were: the presence of night-sweats (OR=0.46 [0.24-0.88]; P=0.018), the presence of thoracic pain (OR=0.27 [0.14-0.54]; P<0.001), screening for HIV (OR=0.41 [0.17-0.98]; P=0.045), fact to inform a person of its disease (OR=0.06 [0.01-0.41]; P=0.004), the application of directly observed treatment in the community (OR=0.34 [0.17-0.66]; P<0.001). CONCLUSION: Reducing loss to follow-up during treatment for tuberculosis requires the development of a "good attitude" through education-information about tuberculosis.
