Basic Coagulation Parameters among Human Immunodeficiency Virus-Infected Adults in Gondar, Northwest Ethiopia: A Comparative Cross-Sectional Study

Abstract EN

Objective.

We aimed at assessing the basic coagulation parameters of HIV-infected adults at the University of Gondar Hospital antiretroviral therapy clinic.

Methods.

A comparative cross-sectional study was conducted from February to May 2017.

A total of 300 study participants, consisting of 100 HAART-naïve HIV-infected adults, 100 HIV-infected adults who were taking HAART, and 100 HIV-seronegative apparently healthy adults, were included.

Basic coagulation functional assays such as PT, APTT, and INR were determined by coagulation analyzer.

CD4 cells and platelet count were analyzed by FACS count and SYSMEX K-21N automated analyzer, respectively.

The data were entered, cleaned, and edited using Epi Info version 7 and analyzed using SPSS version 20.

Kruskal-Wallis H, Dunn-Bonferroni pairwise comparison test, and Spearman’s rank-order correlation analysis were used for inferential statistics.

The results were expressed by a median and presented in tables.

P value < 0.05 was considered as statistically significant.

Results.

PT, APTT, and INR were significantly higher, whereas platelet count was significantly lower in HIV-infected adults (both who were taking HAART and HAART-naïve) than HIV-seronegative adults (P<0.001).

PT and INR were significantly higher, and platelet count was significantly lower in HAART-naïve HIV-infected adults than HIV-infected adults who were taking HAART.

In Spearman’s rank-order correlation analysis, APTT has shown a significant negative correlation with a CD4 count in HAART-naïve HIV-infected adults.

Conclusion.

HIV-infected adults are more likely to develop coagulation abnormality than HIV-seronegative subjects.

Coagulation parameters need to be checked regularly to monitor coagulation disorders in HIV-infected adults.
