Tuberculosis treatment outcomes were assessed according to World Health Organisation guidelines. Determinants of unsuccessful treatment outcomes were identified using a multivariable logistic regression analysis.RESULTS: Between January 2011 to December 2012, 1180 rural TB patients started treatment, of whom 494(41.9%) were female. The treatment success rate was 893(75.7%), while the rates of death, loss-tofollow-up, and treatment failure were 129(10.9%), 100(8.5%), and 18(1.5%) respectively. In the final multivariable logistic regression model, the odds of unsuccessful treatment outcome were higher among patients who received care at the urban public facility(a OR = 2.9, 95%CI: 1.9-4.4), smear-negative(1.3,1.0-1.8) and extrapulmonary(2.7, 1.3-5.6) TB patients, human immunodeficiency virus(HIV) co-infected(2.1, 1.5-3.0), and patient who received the longer(8-mo) anti-TB regimen(1.3, 1.1-1.8).CONCLUSION: Treatment success among rural TB patient in Nigeria is low. High risk groups should be targeted for closer monitoring, socio-economic support, and expansion of TB/HIV activities.展开更多

It has become an emerging concern to epidemiologists and TB control programs due to complexities in its control and management. Managing MDR-TB, DM and HIV comorbidity is challenging, with risk of unfavorable outcome;consequently, close monitoring is necessary. Individuals with weak immunity resulting from diseases such as uncontrolled Diabetes Mellitus (DM) and HIV have a higher risk of developing TB or progression from latent to active TB. We present a 65-year old known diabetic patient who presented to Royal Cross Hospital Ugwueke Abia State, Nigeria with a one-year history of recurrent productive cough with associated night sweats, low grade fever and marked weight loss. A diagnosis of drug-resistant TB with DM/HIV co-morbidity was made and co-managed by experts from the respective clinics and the State TB control program. The patient was declared cured (7 months consecutive negative cultures each taken 30 days apart) after completing 20 months of conventional MDR-TB treatment. The patient showed remarkable clinical improvement including weight gain, good diabetic control and significant increase in CD4 (700 cells). Managing MDR-TB patients with diabetes and HIV is challenging, however, appropriate treatment, psychosocial support, adequate blood sugar control as well as monthly monitoring of patients with requisite investigations are vital in achieving good treatment outcome.展开更多

Nigeria is among the three countries that account for half of the 4.3 million “missing” TB cases globally. One untreated TB case is able to infect about 10 - 20 people annually. Hence, it is pertinent that TB is controlled effectively through the use of active case finding strategies to find the missing TB cases. Objective: This article highlights the best practices and key lessons learnt during the implementation of the active house to house TB case finding strategy in Nigeria. Lessons Learnt and Recommendations: Strategic community engagement, massive awareness creation using mass media and local means of communication, mapping of locations where registered TB cases live, to inform home visits for contact tracing and strengthening of laboratory systems, are viable mechanisms to improve TB case finding. Conclusion: Active TB case finding interventions should be implemented in the context of a strengthened diagnostics system, strategic community engagement and media involvement.展开更多
