HIV or Liver Mortality
Slide #18: Survival of Patients Coinfected With HIV and Hepatitis B or C Virus
Bonacini and colleagues conducted a prospective, university clinic cohort study of 472 patients with HIV infection who were followed for 8343 patient-months.1
Patients were divided into 4 subgroups:1
HIV/HBV (n=72).
HIV/HCV (n=256).
HIV/HBV/HCV (n=18).
HIV alone (n=126).
Liver deaths were significantly more common in patients with multiple hepatitides (28%), HIV/HBV (15%), and HIV/HCV (13%), versus HIV alone (6%).1
Its important to note that liver mortality was comparable in HIV/HBV as in HIV/HCV-coinfected patients.
Finally, in patients with hepatitis co-infection, initial CD4 cell count higher than 200 cells/mm3 and use of HAART were independently associated with reduced mortality.
These results suggest that control of immunosuppression using HAART and keeping CD4 cell count above 200 should be one of the first priorities in patients with HIV and any viral hepatitis co-infection. Control of hepatitis viruses needs to be considered after HIV is suppressed or as a primary endpoint in selected patients with early untreated HIV disease.1

16. HAART and Liver Fibrosis in HIV/HCV Coinfected Patients
HAART may slow fibrosis progression
HIV/HCV coinfection versus HCV monoinfection post-HAART: No difference in:
Fibrosis progression rate (P=.29)
Fibrosis stage (P=.87)
Necroinflammatory grade (P=.89)
Fibrosis progression rate (FPR) in Coinfected patients:
Strongly correlated with HIV RNA levels
Coinfected patients with any HIV RNA >400 copies/mL had a faster FPR than coinfected patients with HIV RNA <400 copies/mL (P=.004)
Coinfected patients with HIV RNA <400 copies/mL had a similar FPR to HCV monoinfected patients (P=.253)
Increased with CD4 cell counts <500 cells/mm3 combined with HIV RNA >400 copies/mL (P=.005)
HAART and Liver Fibrosis in HIV/HCV Coinfected Patients
Brau and colleagues’ retrospective chart review found that HAART may slow fibrosis progression
Post-HAART:1
HIV/HCV coinfection versus HCV monoinfection, there was no difference in:
Fibrosis progression rate (P=0.29).
Fibrosis stage (P=0.87).
Necroinflammatory grade (P=0.89).
Fibrosis progression rate (FPR) in HIV/HCV-coinfected patients was strongly correlated with HIV RNA levels and was increased with CD4 cell counts <500 cells/mm3 combined with HIV RNA>400 copies/mL (P=0.005).
HIV/HCV coinfected patients with any HIV RNA < 400 copies/mL had a faster FPR than coinfected patients with HIV RNA < 400 copies/mL (p=0.004)
HIV/HCV coinfected patients with HIV RNA < 400 copies/mL had a similar FPR to HCV monoinfected patients (p=0.253)

48-week exposure data from 8 clinical trials
819 adult HIV-infected patients
Hepatitis positive: 132 patients with HCV and/or HBV coinfection
Hepatitis negative: 687 patients
5-year exposure data from Study M97-720
Lopinavir/ritonavir
At least as safe as nelfinavir
6.9% to 12.8% experienced grade 3+ ALT elevations
Overall coinfected patients did have 3 to 4 fold higher risk of ALT and AST elevations versus those without hepatitis
Slide #107: Meta-Analysis: Lopinavir/Ritonavir Efficacy in HIV/HCV-Coinfected Patients
da Silva and colleagues retrospectively compared 819 HIV/HCV and/or HBV-coinfected patients to 687 non-coinfected patients in several clinical trials of lopinavir/ ritonavir, with respect to virologic and immunologic response, and the risk of AST/ALT elevations. In addition, 5-year exposure data from Study M was also evaluated.1
Lopinavir/ritonavir was found to be at least as safe as nelfinavir.1
6.9% to 12.8% experienced grade 3+ ALT elevations.
Overall coinfected patients did have 3 to 4 fold higher risk of ALT and AST elevations versus those without hepatitis.

47. Summary of PIs and Hepatic Safety
Rate of serious clinical (symptomatic) hepatotoxicity, ALT and/or AST levels >5 times ULN is relatively low
Boosting doses of ritonavir not associated with significantly higher incidence of severe hepatotoxicity versus other PIs
Patients coinfected with HBV and/or HCV
Greater risk of hepatotoxicity
Lopinavir/ritonavir appears at least as safe as nelfinavir
Boosted PIs can help suppress resistance to other ARV agents
More data for atazanavir and fosamprenavir are needed in this patient population

48. Conclusions

49. Conclusions High prevalence of HIV-hepatitis coinfection
HIV RNA and CD4 are correlated with fibrosis progression in coinfected patients
Use of NNRTIs is associated with increased risk of hepatotoxicity
For PI regimens, no increased risk if ritonavir dose <200 mg bid

50. Conclusions, cont.
Patients treated with boosted PIs tend to have a lower incidence of grade 3/4 AST and ALT elevations than patients treated with nelfinavir
Boosted PIs tend to suppress HIV RNA better than nelfinavir in HIV/HCV coinfected patients
Boosted PIs can help suppress resistance to other ARV agents (eg, tenofovir DF)

Slide #9: Recommended Regimens for Treatment-Naïve Patients: DHHS 2006
On May 4, 2006, the Panel on Clinical Practices for Treatment of HIV Infection, sponsored by the DHHS, provided its recommendations for the use of antiretroviral agents in treatment-naïve HIV-infected patients.1
Data from the growing number of clinical trials allowed the panel to recommend the use of specific antiretroviral combination regimens as being preferred for first-line use or for alternative regimens.
Preferred regimens:1
PI-based: lopinavir/ritonavir + zidovudine + (lamivudine or emtricitabine).
NNRTI-based: efavirenz + (zidovudine or tenofovir DF) + (lamivudine or emtricitabine). Administration of this NNRTI-based regimen is not recommended during pregnancy, particularly during the first trimester, or in women with high pregnancy potential.
The panel also identified a number of alternative regimens that may be useful under conditions when the preferred regimens may not be the best choice for an individual patient.1

53. Thank You!

54. Case 1- HCV Diagnosis in HIV Infected Patient
43 y/o WM, unemployed, h/o IDU, found to be HIV positive last year. No f/u until today when he presents to clinic for evaluation
You obtain labs and determine that his CD4 count is 227 (14%), HIV VL 84,000, Hemoglobin 13, ALT 51 and HCV Ab, HBV sAg are negative. No current meds.
Given his HIV VL and CD4 count ARV Rx is recommended.
In your consideration about ARV regimens in this patient, you discuss potential liver toxicity.
Despite negative hepatitis serologies is any further or repeat testing warranted?

55. Case 2- HIV Treatment in the HIV/HCV Coinfected Patient
37 y/o AAF was diagnosed with HIV/HCV about 4 years ago. Remote h/o IDU and minimal ETOH intake. Has ongoing depression. Works as a medical assistant. Current meds are Zoloft and as needed ibuprofen.
Current Labs today: HCV VL 7.1M genotype 1b, Chol 220 (LDL 131), ALT 51
CD4 count has been in the 400s, HIV VL 12,000, but over the last couple of years has drifted down to 300 (17%) and the HIV VL is now 47,500.
What type of ARV regimen would you consider using in this patient?

56. Case 3- HCV Treatment in the HIV/HCV Coinfected Patient
51 y/o HM with HIV/HCV for over 10 years. Intermittently employed as a house painter. H/o HTN, smoker, on ARV Rx (Sustiva, Truvada) with an undetectable HIV VL and CD4 count 451 (21%). His BMI is 29. Other labs include HCV VL 27.5M genotype 1a, ALT 67, Chol 247 (LDL 185), TG 97
Liver biopsy 2 years ago showed grade 2 fibrosis and no cirrhosis.
Although adherent to meds, he has missed a few appointments.
Is this patient a candidate for HCV Treatment? What factors go into your decision?
