Measurement of Plasma Fibrinogen Levels, PT and APTT among HIV Infected Patients: A Critical Bio-Marker for Coagulation Dysfunctions

Background: The literature stated that Human immunodeficiency virus (HIV) infection led to activation of coagulation, and habitually linked with an augmented risk of venous and arterial thrombosis. So the purpose of the study was to determine the plasma fibrinogen level in Sudanese HIV-infected patients.

Materials and Methods: A total of one hundred participants were recruited, and classified into two groups; the case group include (50) HIV patients, and the control group enrolled (50) healthy individuals. Three ml of blood was collected. Fresh Poor Plasma was prepared from citrated venous blood by centrifuged for 15 minutes at 3000 pm. Fibrinogen levels were measured by an automated coagulation analyzer (Thrombolyzer XRC Germany). Data were collected using a directly structured questionnaire. Data were analyzed using SPSS Version 21.

Results: The present study showed that the mean of plasma fibrinogen levels was statistically significantly higher in HIV infection in comparison with those normal healthy control (470.50 ±67.75 vs 214.75±21.25 with P-value 0.00). There was a significantly decreased level of PT, and PTT among the HIV group comparing with the control (9.575±0.64, and 22.39±4.94) VS (12.483±0.72, and 30.78±3.55) consequently, (P-value ≤0.001). Fibrinogen levels were significantly increased with the progression of HIV disease (469.84 ±67.15, 472.74 ±87.75, 478.47 ±61.92) in stage I, stage II, and stage III respectively.

Conclusions: An HIV-infected patient had elevated plasma fibrinogen levels, as well as other coagulation dysfunctions.
