Peripheral neuropathy and associated factors among children living with HIV on antiretroviral therapy in Gamo zone, Southern Ethiopia: an institution-based cross-sectional study.

Background: Peripheral neuropathy (PN) is a common neurological complication of HIV (Human Immunodeficiency Virus) that can significantly affect patients' quality of life. In Ethiopia, children living with HIV are at an increased risk of developing peripheral neuropathy due to comorbidities such as anemia, tuberculosis, malnutrition, and poor socio-economic status. Our study aims to evaluate the prevalence of peripheral neuropathy among children living with HIV in Ethiopia using a simple clinical screening tool.

Methods: A health institution-based cross-sectional study was conducted among 148 children aged 5 to 18 years living with HIV who are receiving treatment at the antiretroviral therapy (ART) clinic of the randomly selected public health institutions in the Gamo zone. An interview and neurologic examination were conducted. A binary logistic regression model was used to identify factors associated with the outcome variable. Variables with p-value < 0.25 in the bi-variable logistic regression analysis were entered and checked for association in a multivariable logistic regression model. The level of statistical significance was declared at the p-value < 0.05.

Result: In this study, 148 children participated, making a response rate of 97.5%. The mean ± standard deviation (SD) age of the respondents was 15.03 ± 2.99 years, and 81(54.7%) were male. The magnitude of PN was 20.9% (31/148). Children in the age category of 15-18 (adjusted odds ratio (AOR) = 1.88, 95%CI; 1.24-4.60), low BMI for age (AOR = 1.66, 95%CI; 1.12-4.15), last exposure to isoniazid within 1 year (AOR = 2.31, 95%CI; 1.12-8.53). Longer duration of HIV illness (AOR = 2.17, 95%CI; 1.54-4.64), and past tuberculosis (TB) treatment (AOR = 2.11, 95%CI; 1.08-7.48) were significantly associated factors with peripheral neuropathy.

Conclusion: Our analysis revealed that being in the age category of 15-18 years, low BMI for age, Isoniazid exposure, longer Duration of HIV illness, and past TB treatment were significantly associated with peripheral neuropathy in children living with HIV. These disease-related factors may contribute to the development and progression of peripheral neuropathy in this population.
