Hematological profile of HIV patients in relation to immune status - a hospital-based cohort from Varanasi, North India.

OBJECTIVES

To study the spectrum of hematological manifestations and evaluate the relationship between various hematological manifestations and CD4 cell counts in a hospital-based cohort of HIV-infected adults in and around Varanasi, North India.

MATERIALS-METHODS: The clinical and hematological profiles of the patients attending the Infectious Disease Clinic, Varanasi, India were recorded. The relationship between CD4 counts and various hematological manifestations was analyzed.

RESULTS

A total of 470 HIV-infected individuals were followed for 830 person years of observation (PYO). Rate of hematological episodes was 1047 episodes per 1000 PYO. CD4 counts were significantly lower in individuals with severe anemia and neutropenia compared to those without. However, no relation could be established between thrombocytopenia and CD4 counts. In the above- mentioned population, CD4 levels were significantly lower in those with anemia/neutropenia harboring any particular disease compared to those who had the same disease without anemia/ neutropenia.

CONCLUSIONS

There is a strong negative association between CD4 counts and the severity of anemia and neutropenia in this population. They can be considered as good clinical indicators to predict and access the underlying immune status. Though fall in the CD4 levels during neutropenia is observed, it is difficult to comment since the estimations of CD4 rely on the total leukocyte counts. However, the relation between anemia and disease progression is straight forward and quite useful for the treating physician.
