Description:
Hodgkin lymphoma (HL) occurs in HIV-infected individuals more frequently than in the HIV-negative population and the incidence is rising. Patients (pts) with non-Hodgkin’s lymphoma in HIV appear to have improved outcomes if they receive HAART with chemotherapy (CT). ABVD is standard CT for HL and is frequently administered with HAART in pts with HIV-HL. However, some components of the ABVD regimen may interact with antiretroviral (ARV) medications to alter metabolism and increase toxicity. In particular, vinblastine (VBL) is metabolized by CYP3A4 and protease inhibitors, particularly ritonavir (RTV), appear to inhibit this cytochrome potentially leading to higher VBL exposure. Little definitive information is available regarding how interactions might affect clinical outcome. We conducted a retrospective review of 36 pts with HIV-related HL to identify the frequency of neurotoxicity (NT), hematologic toxicity (HT), and lung toxicity (LT), to identify risk factors for severe (grade III–IV) toxicity, and to determine its clinical significance. Clinical data were collected from the CFE database and by chart review from 3 centers. The median age at HL diagnosis (dx) was 41 (range 29–66) years and 34 (94%) were male. HL was advanced stage in 28 (78%). Hasenclever score could be calculated in 23 pts and was 0–4 and ≥5 in 15 and 8 pts respectively. ECOG PS was 0–1 in 13 and ≥2 in 8 (n=21). HIV risk factor was: sexual, n=21 and other, n=5 (n=26). Median CD4 count at HL dx was 210 (2–660) cells/ul (n=31). Median HIV viral load (VL) was undetectable (
