| dc.description.abstract | Introduction: Cryptococcal meningitis is the most common central nervous system opportunistic infection in HIV seropositive individuals in sub – Saharan Africa, with South Africa having the highest prevalence. The cerebrospinal fluid findings indicate a lack of inflammatory response. Our study investigates if the cerebrospinal fluid (CSF) inflammatory response can be correlated to CD4+ counts level. Methods: This was a retrospective cohort study of all patients with HIV associated cryptococcal meningitis at Charlotte Maxeke Johannesburg Academic Hospital. Demographics, CD4+counts and CSF findings were collected through all discharge summaries. Spearman’s rank-order correlation statistic was used to assess the correlation between CD4+ counts and cerebrospinal fluid (CSF) inflammatory response. An R of +1 suggests a positive correlation, and a p-value < 0.05 was considered significant. Results: One hundred and thirteen patients were included in the study. All were HIV seropositive, 44.25% (n = 50) were newly diagnosed and 44.25% (n = 50) were known. Thirtyfour out of the fifty in the known HIV category were on antiretroviral treatment. Eighty – three percent (n = 94) of patients had CD4+ counts that were under 100 cells/ µL with the median CD4+ count of 21 cells/µL [Interquartile range (IQR): 9.00 – 56.00]. There was no statistically significant correlation between CSF polymorphonuclear cells and CD4+ count with a p-value of 0.068; however, there was a significant correlation with CSF protein with a p-value of 0.008. Conclusion: There was a partial correlation between CD4+ counts and cerebrospinal fluid inflammatory response. Antiretroviral treatment did not significantly impact the CSF fluid inflammatory response, as suggested by other studies. | |
