Abstract: It is crucial to ensure an optimal clinical management of HCV infection in HIV-co-infected persons. The reasons for the development of guidelines on HCV-infection treatment in HIV-infected persons arise from the need for a standardised management of HIV/HCV coinfection in our Institute. The aim of these guidelines are: to clarify principles of clinical management of HCV infection in HIV-infected patients to care-providers; to improve the awareness of HIV-infected patients cared for our Institute on current management of HCV infection; to improve the quality of care on this topic. These guidelines, based on Evidence based Medicine principles, have been developed by a panel of experts, who conducted a systematic review of the literature, mainly taking into account current international recommendations. In the present document, the most frequent clinical presentation occurring in the management of HIV/HCV co-infected patients at our Institution are discussed. The adherence to present guidelines and their effectiveness at our Institution, outcome indicators will be evaluated. The present guidelines cannot entirely substitute the judgement of an expert clinician. However, adherence to these guidelines will contribute to the improvement of the standard of care of HIV/HCV-co-infected persons.

Abstract: In the pre-highly active antiretroviral therapy (HAART) era, clinical trials showed that interferon (IFN) treatment was able to delay AIDS progression and prolong survival. Along with HAART, ancillary use of IFN during primary infection and before HAART therapy initiation has been effective. Also endogenous IFN may positively affect the progression of HIV infection, as suggested in GB virus type C (GBV-C) coinfected patients. In this pilot study, we tried to prevent rebound of HIV replication in patients who interrupted HAART by covering the drug-free time with administration of pegylated IFN (PEGIFN). Twenty-four HIV-hepatitis C virus (HCV) patients who started IFN treatment for liver disease, after variable time from having interrupted HAART, were enrolled. HIV RNA was determined during a 2-month period. In patients who interrupted HAART at variable times before initiating IFN and, therefore, had experienced a complete viral rebound, IFN caused a significant reduction of viral load lasting at least 4 weeks. Moreover, 3 of the 4 patients who started IFN concomitantly with the HAART discontinuation showed complete control of viral rebound, delaying the resumption of viral replication for more than 2 weeks. These preliminary findings suggest that a structured therapy interruptions (STI) strategy may be feasible provided that IFN is administered during the drug-free times, possibly delaying drug resistance, lessening toxicity, reducing costs, and prolonging survival.

Abstract: Virakinetics II was designed as an observational, multicenter cohort study conducted in HIV-positive patients treated with NFV-based combinations. Trough (pre-dose) concentrations of NFV+M8 in plasma were determined using a novel ELISA test (NFV TDM-ELISA) and analyzed using clinical and laboratory parameters. Drug levels were sorted as below, within or above a given interval (<0.8 microg/mL, 0.8-3.5 microg/mL and >3.5 microg/mL, respectively). Longitudinal analysis was performed in a subset of patients who underwent two or more determinations. Ninety patients on NFV-containing HAART were enrolled and 43 were coinfected with HCV and/or HBV. Among coinfected patients, 10 subjects had a clinical or histological diagnosis of cirrhosis. Compared to the HIV-monoinfected, the coinfected patients were significantly older, more treatment-experienced, with higher frequency of lipodystrophy and altered liver function test values (all p values: <0.05). Coinfected patients were also more likely to be on a reduced dose of NFV than monoinfected (p=0.03). No significant difference was observed between the two groups with regard to NFV+M8 trough values and concentration range distribution. Median NFV+M8 C(trough) concentrations were higher in coinfected patients, but without reaching statistical significance (p=0.2). This new ELISA test proved to be a rapid, convenient and reliable tool for assessing NFV+M8 plasma levels in HIV-positive patients. It could be suitable for use within the framework of routine clinical practice even in peripheral centers without specialized laboratories.

Abstract: PURPOSE: The aim of this study was to evaluate the opportunity of surgical treatment in terms of liver resection or liver transplantation in HIV positive patients affected by an end stage liver disease that referred to our liver unit. METHODS: Among 1350 outpatients who referred to our liver unit from January 2002 to September 2003, thirty-two (2,4%) were HIV positive. The routes of transmission of the viral infection, the related co-infections and the underlying liver disease were recorded. The therapeutic pathway was analysed. The kind and the duration of the surgical procedures were assessed. RESULTS: Fourteen (44%) of these thirty-two patients were not suitable for surgical treatment. Surgery was planned in 9 of 32 HIV positive patients (28%). Four patients (12%) were submitted to liver resection and OLT was performed in five patients (15%). Hepatocellular Carcinoma was present in 4 (44%) of the HIV positive patients considered for surgery. CONCLUSIONS: In conclusion in our centre the 28% of HIV positive out patients had the opportunity to receive a surgical treatment. The candidate to this surgery is mostly young, HCV and/or HBV coinfected and affected by HCC in 44% of cases.

5 Article Liver enzyme elevation in hepatitis C virus (HCV)-HIV-coinfected patients prior to and after initiating HAART: role of HCV genotypes. 2006

Abstract: Transaminase elevation is frequently seen in hepatitis C virus (HCV)-HIV-coinfected patients receiving antiretroviral therapy (ART), representing an increase in the immune response against HCV and being one of the mechanisms proposed to be involved. There is a report claiming that HCV genotype 3 is an independent risk factor. Our objectives were to assess the incidence of liver toxicity in an HIV-HCV-coinfected population with relatively preserved cellular immunity, and the role of HCV genotypes in the elevation of liver enzymes, both at baseline and after initiating ART. All HIV(+) patients with positive anti-HCV serology and CD4(+) cell counts above 100/mm(3) who began triple ART were identified, and their HCV-RNA levels and HCV genotype were determined. Liver enzymes were determined at baseline and bimonthly during follow-up. Of anti-HCV patients 147 were included, 128 (87.1%) of whom had detectable plasma HCV-RNA. HCV-1 and HCV-4 genotypes were found to confer an increased probability of having at baseline transaminases within normal limits over the other genotypes. Severe transaminase elevations (grades 3 and 4) occurred in 5/124 patients (4.0%), all with high pre-HAART ALT and positive HCV-RNA levels. Multivariate analysis showed that patients with genotype HCV-3 had a 3.27 times higher risk of developing HAART-related transaminase elevations of any grade. In conclusion, subjects with the HCV-1 genotype more often had transaminases within normal limits at baseline. The incidence of severe transaminase elevation after initiating ART was very low (4%) in this HIV(+) population with relatively preserved cellular immunity. HCV genotype 3 was identified as a risk factor for the development of transaminase elevation of any grade.

6 Article CD1d expression by hepatocytes is a main restriction element for intrahepatic T-cell recognition. 2005

Abstract: The liver has specific mechanisms to protect itself from infectious agents and to avoid autoimmunity, indicating an important role of the hepatic tissues in antigen presentation and tolerance induction. Since intrahepatic lymphocytes may contribute to the innate immunity and to the liver pathology, it is of interest to analyze the expression of antigen presenting molecules and of the related T cell recognition in liver, and how these change in relation to different diseases. We analyzed the expression of MHC class I, and of CD1-a, -b, -c, and -d proteins on liver tissues from patients with different hepatic diseases. Moreover, in the same patients we studied the intrahepatic and peripheral NKT cell recognition of alpha-galactosyl ceramide antigen in the context of CD1d. Unlike in other tissues, classical MHC class I molecules were poorly expressed in the hepatic compartment, suggesting that inflamed hepatocytes may trigger weak MHC-restricted T cell responses. Nevertheless, we observed a prevalent expression of HLA class I-like CD1d isoform on the hepatocyte surface, indicating that CD1d is the main restriction element in the liver. In patients with viral hepatitis, the intrahepatic CD1d expression parallels the recruitment of CD56+Valpha24Vbeta11+ NKT cells in the liver which recognize CD1d presenting glycolipids such as alpha-galactosyl ceramide, suggesting that the intrahepatic T cell immunity may focus on glycolipid antigens.

7 Article Prevalence and risk factors for human immunodeficiency virus-associated neurocognitive impairment, 1996 to 2002: results from an urban observational cohort. 2005

Abstract: To assess prevalence and risk factors for human immunodeficiency virus (HIV)-related neurocognitive impairment (NCI), the authors performed a 7-year survey in the period 1996 to 2002. A total of 432 patients were examined. HIV-related NCI was diagnosed in 238 patients (55.1%), meeting the HIV dementia (HIV-D) criteria in 45 (10.4%). The prevalence of both NCI and HIV-D did not change significantly during the study period. Compared with patients without NCI, patients with NCI were older (40.4 versus 38.2 years; P = .003), had a higher prevalence of positive HCV serology (61.1% versus 38.9%; P = .003), and a lower nadir CD4 cell count (156 versus 222 cells/microl; P < .001). Compared with patients seen during 1996 to 1999, patients with NCI seen during 2000 to 2002 were older (40.7 versus 38.8 years; P = .004), had a less advanced disease stage (previous acquired immunodeficiency syndrome [AIDS] 28.8% versus 65.7%; P < .001) and a higher nadir CD4 count (174 versus 132 cells/microl; P = .026). This study showed an unchanged prevalence of both HIV-related NCI and HIV-D in the period 1996 to 2002. The authors found evidences for new additional potential risk factors for HIV-related NCI (older age, lower nadir CD4 count, positive hepatitis C virus [HCV] serology), and for a change of risk factors for NCI in the late highly active antiretroviral therapy (HAART) era (older age, less advanced disease, higher nadir CD4 count).

Abstract: We report a case of drug-related toxicity after liver transplantation for hepatocellular carcinoma in a HIV-HCV co-infected patient. Before transplant the patient was on a triple antiretroviral therapy (zidovudine and lamivudine and efavirenz) with a stable CD4+ cell count >500 cells/microL. Liver transplantation was performed with a liver graft showing a 10% of macrosteatosis and with a graft-to-recipient body weight ratio of 1.3. Immunosuppression was achieved with tacrolimus, azathioprine and steroids. The antiretroviral therapy was resumed in the first postoperative day as the early graft function was in the normal range. After a few hours the patient showed myoglobinuria, rhabdomyolysis and a fast-deteriorating graft function. All drugs were withdrawn except steroids and an empiric therapy with riboflavin and glutathione was maintained for five days until myoglobinuria ended. Nevertheless the serum levels of tacrolimus remained in the therapeutic range for six days when it was reintroduced at a reduced dosage (0.01 mg/kg/die). The postoperative course was complicated by tense ascites and severe hyperbilirubinemia without any rejection episodes. The patient was discharged 48 days post-transplantation with a good liver function. During the following year no signs of aggressive HCV-HIV recurrences were observed and the patient is maintaining a CD4+ cells count >400 without antiretroviral therapy.

Abstract: OLT in HIV infected patients still remains a challenging option requiring a careful monitoring of patients for HCV reinfection, drug interactions and antiretroviral toxicity. Severe adverse events due to HAART have been already reported for post exposure prophylaxis in HIV infected patients. Here we report a case of liver graft toxicity related to HAART in a HIV-HCV co-infected patient (46 yrs-male) with associated a small HCC transplanted with a marginal liver graft. The patient had pre-OLT plasma HIV 1-RNA levels undetectable and CD4+ T-cell count of > 200 cells/microL for 6 months. At day 2 a severe graft dysfunction was observed (AST 1570 U/L, ALT 2180 U/L, BIL tot 8.3 mg/dL, BIL Dir 6.6 mg/dL and PT 35%--INR 2.5). Doppler scan showed hepatic artery always patient. Later the postoperative in-hospital course was complicated by tense ascites and severe cholestasis. Serum bilirubin reached 42 mg/dL in day 12. Hypertransaminasemia ended at day 15 while cholestasis ended after 46 days. Tacrolimus was reintroduced at day 7. A liver biopsy 10 after OLT showed severe intrahepatic cholestasis, centrolobular necrosis and macrovesicular steatosis (30%). The patient was discharged 48 days after OLT with good liver function. After seven months HIV-RNA is still undetectable and HAART has not been restarted. We believe that the early complications we observed may be attributed to a sudden increase in plasma concentration of antiretroviral drugs secondary to drug redistribution from peripheral tissues and hepatic clearance deficiency after OLT. Although a pre-OLT withdrawal of HAART seems unjustified a delayed re-introduction of HAART or the use of less hepatotoxic drugs may be advisable.

10 Article Gammadelta T cell activation by chronic HIV infection may contribute to intrahepatic vdelta1 compartmentalization and hepatitis C virus disease progression independent of highly active antiretroviral therapy. 2001

Abstract: HIV and hepatis C virus (HCV) coinfection is frequently associated with rapid progression of HCV-related disease, resulting in a higher risk of cirrhosis. Data suggest that natural T cells expressing the Vdelta1 T cell receptor rearrangement are recruited in the liver of chronically HCV-infected patients and are increased in the peripheral blood of HIV-infected persons. We studied gammadelta T cell distribution in the peripheral blood and liver of HCV-infected and HIV/HCV-coinfected patients in the presence and absence of antiretroviral therapy. We observed that Vdelta1+ T cells releasing helper T cell type 1 cytokines are compartmentalized not only in the liver of HCV+ patients, but also of HIV/HCV-coinfected persons. HIV/HCV patients showed an increased frequency of both peripheral and intrahepatic Vdelta1 natural T lymphocytes, resulting in a higher degree of hepatic inflammation when compared with patients with other liver diseases. Finally, highly active antiretroviral therapy (HAART) was unable to restore Vdelta1T cell circulation to normal levels in chronically HIV-infected persons. We conclude that gammadelta T lymphocytes released from tissue to the bloodstream circulation under the influence of chronic HIV infection may contribute to intrahepatic Vdelta1 compartmentalization and progression of liver disease, independently of HAART.

Abstract: BACKGROUND: Hepatitis C infection induces an acute and chronic liver inflammation that may lead to cirrhosis, liver failure, or hepatocarcinoma. Since the role of alphabeta T lymphocytes in hepatitis C virus (HCV) immunopathology has been analyzed extensively, we investigated the distribution and functional activation of gammadelta T cell subsets in chronically HCV-infected patients. MATERIALS AND METHODS: Blood samples and liver biopsies from 35 patients with compensated chronic HCV infection were compared in terms of T cell subset distribution, expression of activation markers, gammadelta T cell receptor (TCR) repertoire, and pattern of cytokine production. Moreover, we analyzed whether these immunological parameters were associated with other clinical observations (plasma viremia, ALT levels, Ishak index). RESULTS: Differing from peripheral blood distribution, a specific compartmentalization of Vdelta1 T cells (p < 0.001) was observed in the liver of HCV patients. These cells represented a relevant fraction of intrahepatic T lymphocytes (1.8-8.7%) and expressed the memory/effector phenotype (CD62-L- CD45-RO+CD95+). This phenotype was consistent with selective homing upon antigen recognition. Mitogenic stimulation of Vdelta1 + T lymphocytes recruited in the liver revealed the T helper cell type 1 (Th1) pattern of cytokine secretion. Interestingly, the frequency of interferon-gamma (IFN-gamma)-producing Vdelta1 T cells was associated with an higher degree of liver necroinflammation, measured by the Ishak index. Finally, the T-cell repertoire analysis revealed the absence of Vgamma selection in the TCR repertoire of intrahepatic Vdelta1 T cells. CONCLUSIONS: gammadelta T cell distribution in the peripheral blood differs from the Vdelta1 T cell subset because it is policlonally activated and recruited in the liver of chronic HCV-infected patients. During HCV-infection, this T cell subset may release Th1 cytokines and contribute to the necroinflammatory liver disease.
