Abstract:
Background: HIV and tuberculosis (TB) co-infection is a major worldwide health issue, particularly in Sub-Saharan Africa and Southeast Asia, where the dual disease burden impairs clinical outcomes and healthcare system performance. Monitoring CD4 cell count is critical for managing HIV in co-infected populations since it is a crucial biomarker for immune system function, disease progression, and treatment success. Despite advances in viral load monitoring, CD4 count is still critical for commencing prophylaxis, determining ART timing, and predicting TB-related morbidity. Aim: This narrative review investigates the effect of integrated mobile health (mHealth) treatments on CD4 count outcomes in HIV/TB co-infected patients receiving clinical care. Methods: A comprehensive search was undertaken throughout PubMed, Scopus, Cochrane Library, and WHO Global Health Library. The included studies assessed mHealth modalities such as SMS reminders, mobile apps, and teleconsultations in terms of ART adherence, clinic involvement, and CD4 restoration. Findings: In many low- and middle-income countries, mHealth technologies promote treatment adherence and retention in care, which is indirectly connected to higher CD4 counts. However, the data is inconsistent, with some interventions having low or mixed impacts depending on context, gender, and access inequities. Conclusion: mHealth has the potential to improve immunological results in HIV/TB co-infected people. Nonetheless, its efficacy is context-dependent, emphasising the importance of specialised, regionally adapted tactics that address infrastructure constraints, digital literacy, and patient participation. Future research must prioritise implementation science approaches in order to maximise scale-up and sustainability.
