CD4 and hypertriglyceridemia: Compared with individuals in class 3 presenting with optimal levels of these lipids, those in class 1 with initially high-increasing and slight-increasing TG and TC trajectories were characterized as middle-aged, hypertriglyceridemia at the baseline, initial use of AZT and PIs, and poorer health status at HAART initiation (i.e., CD4 counts of <200 cells/μl).
