It is important to distinguish between decreased platelet/megakaryocyte production or increased peripheral platelet destruction as causes of thrombocytopenia. The measurement of reticulated platelets, plasma glycocalicin and thrombopoietin (TPO) levels are potentially of use as discriminators. Thrombocytopenia occurs in many HIV+ patients, and plasma glycocalicin has previously been shown to be elevated in this patient group. Reticulated platelets, glycocalicin and TPO were measured in samples from 56 HIV+ subjects and 20 healthy normal controls. The glycocalicin index (GCI--the glycocalicin levels adjusted for the platelet count) measured in HIV+ subjects was found to be significantly elevated when compared to normal controls (mean GCI 1.5 and 1.27, p = 0.04), while the percentage of reticulated platelets and TPO levels were not. Thrombocytopenic HIV+ subjects had significantly elevated mean GCI (2.8 and 1.4, p < 0.0001), TPO (85.2 and 27.2 pg/ml, p = 0.002), percentage of reticulated platelets (15.3 and 10.8%, p = 0.01), and significantly reduced absolute numbers of reticulated platelets (16.2 and 24.5 x 10(9)/l, p = 0.0004) when compared to non-thrombocytopenic HIV+ subjects. GCI and percentage of reticulated platelets exhibited a significant positive correlation (r = 0.4, p = 0.002) in HIV+ subjects. The reticulated platelet, TPO and GCI data suggests that thrombocytopenic HIV+ subjects have normal platelet production, and increased peripheral platelet destruction.
