Total lymphocyte counts in adult HIV/AIDS patients in Port Moresby General Hospital.

We carried out a prospective study of total lymphocyte counts in 124 adult patients who were diagnosed with HIV (human immunodeficiency virus) infection and/or AIDS (acquired immune deficiency syndrome) and were admitted to Port Moresby General Hospital (PMGH) from January to June 2003. The median and mean values of lymphocyte counts in these patients were found to be 0.7 x 10(9)/l and 0.9 x 10(9)/l, respectively, with a standard deviation of 0.7, both of which counts are significantly lower (p < 0.0001) than those found in members of a control population who were well and HIV-antibody-negative. We found that the lower the total lymphocyte count, the more clinically advanced was the HIV disease state. Haemoglobin values were also significantly lower in these patients. For 35% of these patients, tuberculosis was the principal diagnosis made upon being admitted. An apparent 11% of the patients who had a clinical suspicion of AIDS were HIV-antibody-negative. Total lymphocyte count methods could be used in developing countries that do not have appropriate facilities for CD4 count and viral load assays in order to monitor the patient's disease state and progression towards AIDS.
