RESUMO
Background: Highly active antiretroviral therapy (HAART) is the medication regimen for the management of human immunodeficiency virus. Over time, it has been dubbed to have revolutionised the clinical course and outcomes of HIV/AIDS. Objective: The objective of this study is to determine the clinical factors associated with the ocular manifestation of HIV/AIDS among patients on HAART. Materials and Methods: This was a descriptive cross-sectional study conducted at the ophthalmology department of the University of Nigeria Teaching Hospital (UNTH) in 2017 among adult patients (≥18 years) attending the hospital's antiretroviral therapy (ART) clinic and selected using systematic random sampling technique. Statistical Package for Social Sciences (SPSS) version 21 was used for data analysis, with variables being summarised using frequencies and proportions. Inferential statistics (t test, Chi-square test, and Fisher's exact test) was used to test associations between variables. A level of significance was set at a P value of less than 0.05 corresponding to a 95% confidence interval. Results: A majority of patients were in WHO stages 1 and 2 of HIV and the mean CD4+ cell count of the whole population was 575.0 ± 512.56 cells/µL, while that of those with ocular manifestations was 315.2 ± 290.76 and 633.7 ± 533.54 cells/µL for those who do not have ocular manifestation. There was a significant association between CD4+ cell count and ocular manifestations such as conjunctival microvasculopathy, anterior uveitis, and cytomegalovirus retinitis. Conclusion: Our results suggest that HAART has some positive effect on the clinical profile of people with HIV/AIDS with CD4+ count being a major determinant of ocular manifestations.
RESUMO
Background: Low/middle-income countries have the highest burden of blindeness and visual impairment, which directly affects the children and indirectly affects their community. Furthermore, the number of blind years suffered by children with low vision or blindness creates a self-perpetuating ripple effect on their development, health and the socio-economic development of their communities. This systematic review aims to interrogate the existing evidence on the prevalence and causes of blindness and visual impairment in Nigerian children to provide evidence to drive health policy. Methods: This was a systematic review without meta-analysis (SwiM) using a narrative synthesis of the evidence reported using the PRISMA guidelines. All primary cross-sectional studies (in English) reporting the prevalence and causes of visual impairment among Nigerian children under 20 years old between 2003 and 2022 were included in this review. PUBMED, AJOL, BASE and ProQuest databases were searched for eligible studies between 6 June and 15 July 2023. The quality of the included studies was assessed using the AXIS tool. Results were extracted and summarised using descriptive statistics. Visual impairment and blindness using the presenting visual acuity in the better eye were reported using the WHO classification. Results: Seventeen studies, involving 16,924 children from 13 states across five geo-political zones in Nigeria, were included in the final analysis of this review. The prevalence of visual impairment was 3.9%, 2.7% and 0.3% for mild, moderate and severe visual impairments, respectively, due to ametropia, cataracts, glaucoma, etc. The prevalence of blindness was 0.2% due to cataracts, corneal scars and optic atrophy. Conclusion: Blindness and visual impairment is still a significant clinical and public health burden among Nigerian children. Hence, there is still a need for clinicians, especially opthalmologists, public health specialists, policy-makers, and other relevant stakeholders to intensify efforts towards the prevention and control of this burden.
