Children infected with HIV on maintenance hemodialysis (HD) have increased mortality with adequate single pool Kt/V, as compared to non-HIV children on HD. It is unclear if HIV subjects on HD have similar dialysis-associated morbidity (DAM) and blood volume changes (dBV) as non-HIV subjects. It is also unclear how those variables are related to left ventricular mass index (LVMI), shortening fraction (SF), pre-and postdialysis blood pressure and mortality. Methods: We investigated the relationship between LVMI, SF and dBV and DAM using noninvasive monitoring of hematocrit in HIV vs. non-HIV subjects and their association with mortality. We used a cross-sectional study design and analyzed 18 pediatric subjects (9 had vertically transmitted HIV) on HDover a 17-month period. HIVsubjects tolerated fluid removal during HD treatments as well as non-HIV subjects. Results: In our study we confirmed an association of LVMI with DAM in subjects on HD. We found that HIV subjects who did not survive had a significantly lower SF and similar viral load as compared to subjects who survived. Conclusions: Noninvasive monitoring of hematocrit in HIV subjects with compromised heart function allows effective ultrafiltration. Routine echocardiography should be periodically performed in allHIV-infected children on renal replacement therapy because subclinical abnormalities, i.e. increased LVMI or reduced SF in this population can be predictors of mortality.
