Objectives:Understanding the factors that influence tuberculosis (TB) treatment outcomes in children is key to designing interventions to address them. This study aimed to determine the case category distribution of childhood TB in Nigeria and assess which clinical and demographic factors are associated with different treatment outcomes in childhood TB.Materials and methods:This was a retrospective cohort study involving a review of medical records of children (0-14 years) with TB in 3 states in Nigeria in 2015.Results:Of 724 childhood TB cases registered during the review period, 220 (30.4%) were aged 0–4 years. A high proportion of patients had pulmonary TB 420/724 (58.0%), new TB infection 713/724 (98.5%), and human immunodeficiency virus (HIV) coinfection 108/724 (14.7%). About 28% (n = 201) were bacteriologically diagnosed. The proportion of TB treatment success was 601/724 (83.0%). Treatment success was significantly higher in children aged 5–14 years than those 0–4 years (85.3% vs 77.7%, P = .01). Factors associated with unsuccessful outcomes in patients aged 0–4 years are male sex (adjusted odds ratio [aOR]: 1.2), HIV-positive status (aOR: 1.2), and clinical method of diagnosis (aOR: 5.6).Conclusions:Efforts should be made to improve TB treatment outcomes in children by ensuring early and accurate diagnosis, focused training of health workers on childhood TB-HIV care, and effective adherence counseling of caregivers.

Background The Lagos State Tuberculosis, Buruli Ulcer, and Leprosy Control Program (LSTBLCP) started engaging private hospitals under the Public-Private Mix (PPM) Program in 2008. The study aimed to evaluate the trend and predictors of successful Tuberculosis (TB) treatment outcomes of patients managed across these private health facilities between 2010–2016 in Lagos, Nigeria. Methods Retrospective review of TB treatment register and treatment cards of patients commenced on TB treatment between January 2010 and December 2016 in 36 private health facilities engaged by the LSTBLCP. Between December 2016 and February 2017, data were collected and entered into Microsoft Excel by trained data entry clerks. The analysis was done using SPSS software. Independent predictors of successful treatment outcomes were determined using multivariate analysis at the statistical significance of p<0.05 and 95% confidence interval. Results A total of 1660 records of TB patients were reviewed. 1535 (92.47%) commenced treatment, while 1337 (87.10%) of all records had documented treatment outcomes. Of the 1337 patients with outcomes, 1044 (78.09%) had a successful treatment outcome, and 293 (21.91%) had an unsuccessful outcome. Majority were male, 980 (59.04%), Human Immunodeficiency Virus (HIV) negative status, 1295 (80.24%), diagnosed with smear, 1141 (73.14%), treated in private not-for-profit (PNFP) hospital, 1097 (66.08%), treated for TB between 2014–2016 (18.96%-19.52%). In multivariate analysis, age>20years (aOR = 0.26, p = 0.001), receiving TB treatment in 2013 (aOR = 0.39, p = 0.001), having genexpert for TB diagnosis (aOR = 0.26, p = 0.031) and being HIV positive (aOR = 0.37, p = 0.001) significantly reduced likelihood of successful treatment outcome. The site of TB, being on ART or CPT, were confounding determinants of successful treatment outcomes as they became non-significant at the multivariate analysis level. Conclusion Treatment outcome among Lagos private hospitals was low compared with NTBLCP and World Health Organization (WHO) target. We urge the government and TB stakeholders to strengthen the PPM interventions to improve adherence, particularly among People Living with HIV (PLHIV) and older TB patients. Hence, promotion of early care-seeking, improving diagnostic and case holding efficiencies of health facilities, and TB/HIV collaborative interventions can reduce the risk of an unsuccessful outcome.

BackgroundNigeria is one of the 30 high burden countries for drug resistant tuberculosis (DR-TB). This study assessed the prevalence and factors associated with rifampicin resistant tuberculosis (RR-TB) in a secondary referral hospital in Lagos State Nigeria.MethodsA retrospective review of presumptive TB register of patients screened for Mycobacterium tuberculosis (MTB) and RR-TB using Xpert MTB/RIF assay at Mainland hospital between January 1 2012 and December 31 2016 was conducted.ResultsA total of 2497 clients were screened for MTB and RR-TB during the study period. The majority (51.4%) were between 25 – 44 years. Male: Female ratio was 1:0.8. Of the 2497 clients screened, MTB was detected in 942 (37.7%) out of which 220 (23.4%) had RR-TB. Age (AOR 1.8, 95%CI 1.3– 2.6, p = 0.001), symptomatic contact with DR-TB patients (AOR 3.3, 95%CI 2.1–5.1, p <0.001) and type of TB (AOR 2.9, 95% CI 1.7 — 5.0, <0.001) were associated with RR-TB after adjusting for age, gender, HIV status and symptomatic contacts with DR-TB patients.ConclusionThe prevalence of RR-TB in new and previously treated TB patients was high in this study. Urgent steps are needed to avert an impending RR-TB epidemic

Background Multimorbidity is increasingly being recognized as a serious public health concern in the control of both drug-susceptible and drug-resistant tuberculosis (DR-TB). This study assessed the pattern of comorbidities and their prevalence in DR-TB patients at treatment initiation in Lagos, Nigeria. Methods A cross-sectional study was conducted. The baseline laboratory records (human immunodeficiency virus [HIV] status, fasting blood sugar, audiometry, thyroid function tests, serum electrolyte, haemoglobin level and pregnancy test) of DR-TB patients initiated on treatment in Lagos, Nigeria between 1 August 2014 and 31 March 2017 were reviewed. Results A total of 565 DR-TB patients’ laboratory records were reviewed, of which 397 (70.3%) had comorbidities. The proportion with one, two, three and four comorbidities was 60.2%, 29.7%, 8.1% and 2.0%, respectively. Anaemia was the most common (48.1%) comorbid condition, while anaemia and hypokalaemia (7.3%), anaemia and hypothyroidism (6.5%) and anaemia and HIV (5%) were most common among patients with more than one comorbid condition. DR-TB patients with comorbidity were significantly older (34.8±12.3 y) than those without comorbidity (32.0±12.8 y) (p=0.038). Of the 176 females in the reproductive age group, 8 (4.5%) were pregnant at baseline. Conclusions The prevalence of comorbidity among DR-TB patients was high. There is a need for the national TB program to expand its DR-TB council of experts and also integrate reproductive health services into DR-TB management in Nigeria.
