Objective
To investigate the relation between interleukin-6 concentration and oxidative status of HIV infected patients with or at risk of Kaposi’s disease in Yaoundé.
Methods
We conducted a two-months cross-sectional study on 87 consenting HIV infected patients followed at the Day Hospital of the Yaoundé Central Hospital. Serum/plasma obtained after centrifugation of blood collected in dry/EDTA tubes was used for the determination of Human Herpes Virus-8 antigen (HHV-8) and Interleukin-6 (IL-6) by the ELISA technique, and that of oxidative stress markers: Malondialdehyde (MDA) reduced Glutathione (GSH) and total antioxidant capacity by spectrophotometry.
Results
Subjects belonging to the [40–50[year-old age group were mainly represented in our study population with 43.7%. The average age was 44.6 ± 10.4 years with extremes ranging from 26 to 72 years. The sex ratio was 0.24. Our population was mainly represented by people infected with HIV type I (90.8%) and 3.4% had developed clinical signs of Kaposi’s disease. The prevalence of the HHV-8 antigen was 57.5%. Immune and oxidative parameters did not vary with age, sex and therapeutic line. We noted a significant increase in IL-6 concentrations in patients positive to the HHV-8 antigen for IL-6 concentrations < 37 (P = 0.005; CI= [0.40; 0.59]. MDA and GSH concentrations increased significantly with the HHV-8 infection (P < 0.0001; CI= [0.40; 0.59] and P < 0.0001; CI= [13.30;21.45], respectively). Total antioxidant capacity (FRAP) decreased significantly with HHV-8 infection (P = 0.004; CI= [-69.18; -13.78]). We noted a significant increase in MDA concentrations in patients taking their ARVs irregularly, (P < 0.0001).
Conclusion
Our study showed a weak positive correlation between IL-6 and MDA, a strong negative correlation between FRAP and MDA and a strong positive correlation between MDA and GSH highlighting the association of these few markers of oxidative stress and Il-6 to the risk of Kaposi’s disease.
