D36 IX	12/1997	390	7500	R5X4	ABC, AZT, NVP (1/1999-9/2004)
D36 X	7/1998	325	NT	R5X4	ABC, NVP, 3TC (9/2004-present)
D36 XI	1/1999	160	9900	R5X4	ABC, NVP, 3TC (9/2004-present)

CD4+ T-cells were measured by flow cytometry. Plasma HIV-1 RNA was measured by COBAS Amplicor HIV-1 Monitor Version 1.0 (Roche Molecular Diagnostic Systems, Branchburg, N.J.). NT, not tested; HIVD, HIV-associated dementia; ABC, abavavir; AZT, zidovudine; NVP, nevirapine; 3TC, lamivudine. *These results have been reported previously [31, 18].
