Relationship of Serum Zinc Level and Macro/Micronutrients with CD4 Levels in HIV Patients

Background: Deficiencies of micronutrients increase the risk of various infections in HIV-infected patients. Zinc deficiency in HIV-infected patients may be associated with decreased CD4 cell counts. Objectives: In this regard, the present study investigated the association between serum zinc levels, macro/micronutrient intake, and CD4 counts in HIV patients. Methods: The research population of this study included 194 adult HIV patients aged 18 to 70 years referred to Shiraz Behavioral Diseases Center, Shiraz, Iran. The CD4 cell counts were extracted from patients’ records. Serum zinc level was measured using atomic absorption method. Univariate and multivariate comparison of macro/micronutrient and food items with CD4 cells was performed using linear regression and SPSS20, and P < 0.05 was considered statistically significant. Results: Fifty-seven percent were male, and the mean age and SD of total participants was 43.76 ± 9.06 years. The association between serum zinc levels and CD4 serum count is close to the significance level (P = 0.05), but the dietary zinc intake was not significantly correlated with serum CD4 counts (P = 0.26). Vegetable intake (P < 0.001) and fruits (P = 0.01) as well as absorption of vitamin A (P = 0.002), vitamin C (P < 0.001), beta-carotene (P = 0.002), folate (P = 0.05), and fiber (P = 0.01) from diet showed a direct and significant association with serum CD4 levels in HIV patients. Consumption of hydrogenated oils (P = 0.04) showed a significant inverse association with serum CD4 levels in these patients. Conclusions: Evaluation of serum micro/macronutrients can play an essential role in the development of appropriate dietary and supplement guidelines provided by the healthcare system for HIV-infected patients, and it can influence the decision- and policy-making regarding the control of non-pharmacological management of these patients.
