Addressing gaps in adolescent tuberculosis programming and policy in Nigeria from a public health perspective

OBJECTIVES

Tuberculosis (TB) is a leading infectious cause of death globally. Of the estimated 10 million people who developed active TB in 2019, 1.8 million (18%) were adolescents and young adults aged 15-24 years. Adolescents have poorer rates of TB screening, treatment initiation and completion compared to adults. Unfortunately, there is relatively less programme, research and policy focus on TB for adolescents aged 10-19 years. This article reviews the scope of health services and the relevant policy landscape for TB case notification and care/treatment, TB/HIV management, and latent TB infection for adolescents in Nigeria. Additionally, it discusses considerations for TB vaccines in this population.

CONTENT

All Nigeria Federal Ministry of Health policy documents relevant to adolescent health services and TB, and published between 2000 and 2020 underwent narrative review. Findings were reported according to the service areas outlined in the Objectives.

SUMMARY AND OUTLOOK

Nine policy documents were identified and reviewed. While multiple policies acknowledge the needs of adolescents in public health and specifically in TB programming, these needs are often not addressed in policy, nor in program integration and implementation. The lack of age-specific epidemiologic and clinical outcomes data for adolescents contributes to these policy gaps. Poor outcomes are driven by factors such as HIV co-infection, lack of youth-friendly health services, and stigma and discrimination. Policy guidelines and innovations should include adaptations tailored to adolescent needs. However, these adaptations cannot be developed without robust epidemiological data on adolescents at risk of, and living with TB. Gaps in TB care integration into primary reproductive, maternal-child health and nutrition services should be addressed across multiple policies, and mechanisms for supervision, and monitoring and evaluation of integration be developed to guide comprehensive implementation. Youth-friendly TB services are recommended to improve access to quality care delivered in a patient-centered approach.

Factors influencing diagnosis and treatment initiation for multidrug-resistant/rifampicin-resistant tuberculosis in six sub-Saharan African countries: a mixed-methods systematic review

BACKGROUND

Drug-resistant tuberculosis burdens fragile health systems in sub-Saharan Africa (SSA), complicated by high prevalence of HIV. Several African countries reported large gaps between estimated incidence and diagnosed or treated cases. Our review aimed to identify barriers and facilitators influencing diagnosis and treatment for drug-resistant tuberculosis (DR-TB) in SSA, which is necessary to develop effective strategies to find the missing incident cases and improve quality of care.

METHODS

Using an integrative design, we reviewed and narratively synthesised qualitative, quantitative and mixed-methods studies from nine electronic databases: Medline, Global Health, CINAHL, EMBASE, Scopus, Web of Science, International Journal of Tuberculosis and Lung Disease, PubMed and Google Scholar (January 2006 to June 2019).

RESULTS

Of 3181 original studies identified, 55 full texts were screened, and 29 retained. The studies included were from 6 countries, mostly South Africa. Barriers and facilitators to DR-TB care were identified at the health system and patient levels. Predominant health system barriers were laboratory operational issues, provider knowledge and attitudes and information management. Facilitators included GeneXpert MTB/RIF (Xpert) diagnosis and decentralisation of services. At the patient level, predominant barriers were patients being lost to follow-up or dying due to lengthy diagnostic and treatment delays, negative public sector care perceptions, family, work or school commitments and using private sector care. Some patient-level facilitators were HIV positivity and having more symptoms.

CONCLUSION

Case detection and treatment for DR -TB in SSA currently relies on individual patients presenting voluntarily to the hospital for care. Specific interventions targeting identified barriers may improve rates and timeliness of detection and treatment.

Adolescent tuberculosis

Adolescence is characterised by a substantial increase in the incidence of tuberculosis, a known fact since the early 20th century. Most of the world's adolescents live in low-income and middle-income countries where tuberculosis remains common, and where they comprise a quarter of the population. Despite this, adolescents have not yet been addressed as a distinct population in tuberculosis policy or within tuberculosis treatment services, and emerging evidence suggests that current models of care do not meet their needs. This Review discusses up-to-date information about tuberculosis in adolescence, with a focus on the management of infection and disease, including HIV co-infection and rifampicin-resistant tuberculosis. We outline the progress in vaccine development and highlight important directions for future research.

Childhood TB: can the End TB Strategy deliver?

The accelerated reductions in global TB incidence required to achieve the End TB Strategy goal will result in reductions in the burden of childhood TB. Contact screening and preventive therapy have emerged as important components of TB burden reduction, and family-centered approaches could be an effective route in delivering these activities. Lack of accurate diagnostics for children remains a critical barrier and a need remains for better collaborative and supportive links between the child health and TB control sectors. Irrespective of whether the ambitious targets can be achieved, the unprecedented opportunities provided by the End TB Strategy must be embraced.
