Abstract: OBJECTIVE: To provide an update of recommendation on antiretroviral treatment (ART) in HIV-infected adults.Methods. These recommendations have been agreed by consensus by a committee of the spanish AIDS Study Group (GESIDA) and the National AIDS Plan. To do so, advances in the physiopathology of AIDS and the results on efficacy and safety in clinical trials, cohort and pharmacokinetics studies published in biomedical journals or presented at congresses in the last few years have been reviewed. Three levels of evidence have been defined according to the data source: randomized studies (level A), case-control or cohort studies (level B) and expert opinion (level C). Whether to recommend, consider, or not to recommend ART has been established for each situation. RESULTS: Currently, ART with combinations of at least three drugs constitutes the treatment of choice in chronic HIV infection. In patients with symptomatic HIV infection, initiation of ART is recommended. In asymptomatic patients initiation of ART should be based on the CD41/mL lymphocyte count and on the plasma viral load (PVL): a) in patients with CD41 lymphocytes < 200 cells/mL, initiation of ART is recommended; b) in patients with CD41 lymphocytes between 200 and 300 cells/mL, initiation of ART should, in most cases, be recommended; however, it could be delayed when the CD41 lymphocyte count remains close to 350 cells/mL and the PVL is low, and c) in patients with CD41 lymphocytes > 350 cells/mL, initiation of ART can be delayed. The aim of ART is to achieve an undetectable PVL. Adherence to ART plays a role in the durability of the antiviral response. Because of the development of cross-resistance, the therapeutic options in treatment failure are limited. In these cases, genotypic analysis is useful. Toxicity limits ART. The criteria for ART in acute infection, pregnancy and postexposure prophylaxis and in the management of coinfection with HIV and hepatitis C and B virus are controversial. CONCLUSIONS: The current approach to initiating ART is more conservative than in previous recommendations. In asymptomatic patients, the CD41 lymphocyte count is the most important reference factor for initiating ART. Because of the considerable number of drugs available, more sensitive monitoring methods (PVL) and the possibility of determining resistance, therapeutic strategies have become much more individualized.

Abstract: The measurement of fibrosis stage critically affects the identification of the progression of liver disease, the establishment of a prognosis and therapeutic decision making. Liver biopsy has been the single, most useful method to determine the degree of liver fibrosis (LF), but with recognized limitations, mainly associated with its invasiveness. In recent years, alternative noninvasive methods have been developed, including imaging methods, such as transient elastometry, and assays based on serum biomarkers. This article reviews the available studies evaluating the value of various noninvasive methods for the assessment of LF in patients with HIV-infection and HBV/HCV co-infection, and makes recommendations on how to best use and combine them in clinical practice.

Abstract: Chronic hepatitis B and C represent a leading cause of morbidity and mortality among human immunodeficiency virus (HIV)-infected patients worldwide. New treatment options against both hepatitis B (HBV) and C (HCV) viruses have prompted us to update previous recommendations for the management of coinfected individuals. Fifteen topics (nine related to HCV, five to HBV and one to both viruses) were selected for this purpose. A panel of Spanish experts in the field was invited to review these areas and propose specific recommendations, which were scored according to the Infectious Disease Society of America (IDSA) grading system. These guidelines represent a comprehensive and updated overview on the management of hepatitis B and C in HIV-infected patients.

Abstract: Co-infection by human immunodeficiency virus and hepatitis B and C viruses is quite common because they share similar routes of transmission. The introduction of highly active antiretroviral therapy has significantly improved the life expectancy of HIV-infected patients in the last few years. However, chronic viral hepatitis represents an emerging cause of morbidity and mortality in this population, either as a result of end-stage liver disease or as a consequence of hepatotoxicity induced by antiretroviral drugs. The main goal of the Consensus Conference was to establish specific recommendations for the management of chronic viral hepatitis B and C in HIV-infected patients. The role of orthotopic liver transplantation for co-infected individuals with end-stage liver disease was also assessed.

Abstract: BACKGROUND: Mood disorders and other neuropsychiatric disorders are common adverse events limiting tolerability of alpha-interferon (IFN) therapy for hepatitis C virus (HCV). Because efavirenz (EFV) frequently produces neuropsychiatric side effects, we studied the effect of EFV in the incidence of these side effects in HIV/HCV patients receiving IFN. METHODS: Prospective cohort of HIV/HCV patients receiving IFN and ribavirin. Adverse events and concomitant medications were systematically recorded once monthly. RESULTS: Among 266 HIV/HCV patients starting a course of IFN (91% pegylated IFN) plus ribavirin, 53 (20%) received concomitant EFV and 213 (80%) did not. Most EFV patients (92%) were already on EFV before starting IFN (mean 26 months). Neuropsychiatric side effects were frequent, without significant differences between both groups (79% vs 65%, P = 0.051), and only 10 patients discontinued IFN. Mood disorders were reported more frequently in EFV patients (36% vs 23%, P = 0.046), but antidepressant therapy use was similar in both groups. The incidence of anxiety, insomnia, irritability, headache or prescription of anxiolytics or hypnotics was similar. CONCLUSIONS: Neuropsychiatric adverse events are common in HIV/HCV patients receiving IFN, usually mild or moderate. EFV may favor symptoms of mood disorders, although it was not related to an increased risk of significant depression requiring specific treatment.

Abstract: The prevalence of injection drug use decreased from 67.3% in 1997 to 14.5% in 2006 among Spanish patients infected with human immunodeficiency virus (HIV). A parallel decrease in the prevalence of coinfection with hepatitis C virus was observed, from 73.8% in 1997 to 19.8% in 2006. This steady decrease in the prevalence of coinfection among Spanish patients was caused by a change in transmission routes of HIV infection.

Abstract: Tuberculosis characteristics and incidence were assessed among patients with concurrent human immunodeficiency virus infection and chronic hepatitis C virus infection who were receiving interferon-based therapy at 3 hospitals in Spain. Four of 570 patients (0.7 cases per 100 person-years; 95% confidence interval, 0.19-1.78 cases per 100 person-years) received a diagnosis of tuberculosis; all of them presented with a decrease in CD4+ cell count before diagnosis, and 3 of them received a delayed diagnosis. After tuberculosis treatment, all patients were cured.

Abstract: To describe characteristics and prognosis of patients with suboptimal immunological response to combined antiretroviral therapy (CART). Using data from a multicenter cohort study, we selected patients who initiated CART and showed suboptimal CD4-T cell response (defined as <50 cells/L increase) after 1 year of therapy, despite sustained virological suppression. Characteristics of those patients were compared with subjects who showed optimal immunological response. Of 650 patients with virological suppression, 108 (16.6%) showed suboptimal CD4-T cell response. Independent predictors of suboptimal response were previous injection drug use (OR, 1.85; 95% CI, 1.12-2.98) and age at CART initiation (OR, 1.04 per year increase; 95%CI, 1.01-1.06). Hepatitis C virus coinfection was not associated with impaired immunological response. As compared with patients with optimal immunological response, those with suboptimal response had a higher mortality rate (3.22 versus 0.71 per 100 person-years; p=.001), but a similar rate of new AIDS-defining events. In patients with sustained virological suppression with CART, previous injection drug use, but not hepatitis C virus coinfection, and older age at initiation of therapy were associated with suboptimal CD4 T-cell responses. Patients with suboptimal response had a higher mortality over time, mainly due to diseases other than AIDS-defining events.

Abstract: BACKGROUND: Current stopping rules during pegylated interferon (peg-IFN)/ribavirin (RBV) treatment rely on week 12 HCV RNA response, but earlier identification of non-responders offers clinical and economic advantages. AIMS AND METHODS: To evaluate, among 129 HCV-genotype-1-infected, treatment-naive patients receiving peg-IFN/RBV, the feasibility of predicting treatment failure using receiver operating characteristics (ROC) curves after measuring week 4 HCV RNA decreases, and to assess baseline predictors of not achieving sustained virological response (SVR). RESULTS: Peg-IFN-alpha2b was used in 84.5% of patients. Fifty-three (41%) reached SVR. The best cutoff value of HCV RNA decrease at week 4 to predict non-SVR corresponded to 1 log10 IU/ml: sensitivity and negative predictive value: 100%; specificity: 64%; positive predictive value: 66%; ROC curve area: 0.91 (95% confidence interval [CI]: 0.86-0.96). By applying this threshold, treatment could have been discontinued at week 4 in 64% of virological non-responders (49/76). By univariate analysis, baseline HCV RNA > 800,000 IU/ml (P = 0.029), older age (P = 0.011), and higher aspartate aminotransferase (AST) levels (P = 0.005) or AST/alanine aminotransferase ratio values (P = 0.04) were associated with failure. After multivariate analysis, only baseline HCV RNA >800,000 IU/ml (odds ratio [OR]: 2.12; 95% CI: 1.005-4.488; P = 0.048) and higher AST levels (OR: 1.01; 95% CI: 1.003-1.024; P = 0.011) remained statistically significant. CONCLUSIONS: The lack of > or = log10 IU/ml decrease in baseline HCV RNA at week 4 was 100% predictive of treatment failure, independently associated with HCV RNA > 800,000 IU/ml and higher AST levels.

Abstract: The clinical relevance of occult hepatitis B virus (HBV) infection, defined as detectable HBV DNA serum/liver, in the absence of hepatitis B surface antigen (HBsAg), is unclear. We determined the prevalence of serum occult HBV infection in HIV/HCV co-infected patients enrolled in APRICOT, a randomized multinational trial that investigated the efficacy and safety of peginterferon alfa-2a (40 kDa) plus ribavirin for treatment of HCV. We also examined the effect of prior HBV exposure to liver histology at baseline. Only HBsAg-negative patients were eligible. At screening, serum HBV DNA was assessed by commercial assay (detection limit = 200 copies/mL). Patients were divided into four serological groups: anti-HBs+/anti-HBc+; anti-HBs-/anti-HBc+; anti-HBs+/ anti-HBc-; anti-HBs-/anti-HBc-. Baseline liver biopsy grade and stage were compared among groups. Serum HBV DNA was undetectable in all patients, (n = 866). Results of anti-HBs and anti-HBc was available for 176 patients: 60 (34.1%) anti-HBs+/anti-HBc+; 60 (34.1%) anti-HBs-/anti-HBc+; 11 (6.3%) anti-HBs+/anti-HBc-; 45 (25.6%) anti-HBs-/anti-HBc-. There were no differences among the groups in the histological grade or stage at baseline liver biopsies. Occult HBV infection in serum was not detected in this large immunocompetent cohort. Moreover, prior exposure to HBV did not appear to have any affect on baseline liver histology.

Abstract: Syncytial giant cell hepatitis (SGCH) among adult human immunodeficiency virus (HIV)-infected patients has been rarely described. Most cases have been reported in subjects coinfected with the hepatitis C virus (HCV), but its prevalence and outcome remain unknown. We performed a retrospective analysis of all cases of SGCH among 332 liver biopsies from HIV-infected patients seen at a tertiary center in Madrid, Spain, between 1984 and March 2004. Two hundred fifty specimens were obtained from HCV-coinfected patients. There were 2 cases of SGCH, leading to an observed overall prevalence of 0.6% (0.8% when considering only HCV-coinfected patients). In addition to histological changes secondary to chronic hepatitis C, the liver cords were replaced by syncytial giant cells with up to 30 nuclei. There was no histological evidence of measles (among paramyxoviruses) or herpes viruses group infections. In patient 1, there was a progressive clinical worsening after a 3-month course of prednisone, leading to liver failure and death. His postmortem liver biopsy showed more abundant giant hepatocytes accompanied with the development of a histologic pattern of severe fibrosing cholestatic hepatitis. The second patient received a prolonged course of pegylated interferon-alpha-2b and ribavirin with clearance of syncytial giant hepatocytes despite HCV-RNA persistence. SGCH is a rare histological finding among HIV-infected patients with chronic hepatitis C. Specific treatment with pegylated interferon and ribavirin can lead to histological resolution and biochemical improvement, even in the absence of HCV-RNA clearance.

Abstract: To evaluate, among 70 hepatitis C virus (HCV)-monoinfected and 36 human immunodeficiency virus (HIV)-coinfected naïve patients with genotypes 1/4 receiving weight-adjusted pegylated interferon-alpha-2b/ribavirin, viral kinetics and the feasibility to predict treatment failure measuring early HCV-RNA decreases. HCV-RNA was assessed at baseline, weeks 4, 12 and 24. Receiver operating characteristic (ROC) curves were calculated to determine the most sensitive cut-off values of viral decrease at week 4 predicting treatment failure. Baseline predictors of failure were evaluated by univariate and multivariate analyses. Despite similar baseline HCV-RNA (5.75 vs 5.72 log(10)IU/ml, P = 0.6), HCV monoinfection led to significantly lower HCV-RNA values at weeks 4 (3.7 vs 4.3 log(10)IU/ml, P = 0.01), 12 (2.3 vs 3.5 log(10)IU/ml, P = 0.01) and 24 (1.4 vs 3.3 log(10)IU/ml, P = 0.001) and a higher rates of viral clearance at weeks 24 (60%vs 36%, P = 0.02), 48 (46%vs 25%, P = 0.03) and 72 (37%vs 17%). The lack of achieving an HCV-RNA decrease of at least 1 log(10) at week 4 was highly predictive of treatment failure for HCV-monoinfected patients (Se 100%, Sp 50%, positive predictive value (PPV) 57%, negative predictive value (NPV) 100%, ROC curve area, 0.86 [95% confidence interval (CI) 0.77-0.95], but not for HCV/HIV-coinfected patients (cut-off, 0 log(10), Se 100%, Sp 27%, PPV 21%, NPV 100%, ROC curve area, 0.71 (95% CI 0.49-0.93). HIV coinfection was independently associated with failure (odds ratio 2.95, 95% CI 1.08-8.04, P = 0.01). Thus the magnitude of HCV-RNA decreases at week 4 correlated with treatment response. Significant differences in viral kinetics and cut-off values predicting nonresponse suggest a slower HCV clearance rate in HIV coinfection, which was independently associated with treatment failure.

Abstract: BACKGROUND AND AIMS: Partial splenic embolization (PSE) is a non-surgical alternative for the treatment of hypersplenism. Thrombocytopenia precludes the use of pegylated interferon (peg-IFN) and ribavirin in cirrhotic patients with hepatitis C virus (HCV). We aimed to evaluate the role of PSE as a procedure allowing combined HCV therapy in this setting. METHODS: A retrospective analysis of the safety and rate of sustained virological response (SVR) after a full-dose course of peg-IFN plus ribavirin in eight HCV cirrhotic patients with severe hypersplenism undergoing PSE at a tertiary centre in Madrid, Spain, from May 2002 to August 2004. RESULTS: Six patients (75%) were in Child-Pugh class B (median score 7). PSE significantly improved the mean platelet (P = 0.012), leucocyte (P = 0.017) and haemoglobin (P = 0.035) levels, and prothrombin activity (P = 0.012). After a mean of 20 weeks after PSE all patients started weight-adjusted ribavirin plus peg-IFN-alpha2b (n = 6) or 180 microg/week of peg-IFN-alpha2a (n = 2). Six subjects (75%) completed therapy with no peg-IFN dose reductions; the dose of ribavirin was reduced in two patients reaching haemoglobin levels of less than 10 g/dl (one also received erythropoietin and granulocyte colony-stimulating factor because of neutrophil counts < 300 cells/microl). Three patients (38%) achieved SVR. Portal vein thrombosis was observed in 50% of patients, but did not preclude antiviral therapy. The pathogenic mechanism was multifactorial. It was successfully managed with anticoagulant therapy in two cases. CONCLUSIONS: PSE allowed the safe use of peg-IFN plus ribavirin in HCV cirrhotic patients with severe cytopenias who otherwise would never have been treated. The rate of SVR was 38%.

Abstract: BACKGROUND/AIMS: Differences in HCV-RNA clearance during therapy might explain the lower efficacy of peg-IFN/RBV in HIV/HCV-coinfection. There are limited data on HCV-RNA clearance and treatment outcomes in liver transplanted (LT) patients. METHODS: To assess the rates of SVR and baseline predictors of failure after 48 weeks of weight-adjusted peg-IFN-alpha-2b/RBV in 120 patients with HCV genotype 1: 61 HCV-monoinfected, 40 HIV-coinfected and 19 LT-patients. Viral clearance was evaluated in patients completing 24 weeks of therapy (n=112, 93%). RESULTS: SVR was significantly lower in HIV-coinfection than in HCV-monoinfection or LT (18 vs. 39 vs. 42%, P<0.02). By multivariate analysis, HIV-coinfection (OR 3.048, 95% CI 1.133-8.196; P=0.027), baseline HCV-RNA over 800,000 IU/ml (OR 2.800; 95% CI 1.121-6.993, P=0.027) and higher AST values (OR 1.009; 95% CI 1.001-1.018; P=0.028) were significantly associated to failure. Despite similar baseline HCV load (5.67 vs. 5.75 vs. 5.90 log10 IU/ml), HIV-coinfection showed significantly lower HCV-RNA decreases than HCV-monoinfection at weeks 4 (P=0.015), 12 (P=0.015) and 24 (P=0.0003), and than LT at weeks 12 (P=0.003) and 24 (P=0.023). 36/60 subjects (60%) reaching EVR by week 12 obtained SVR vs. 3/60 (5%) who did not. CONCLUSIONS: HIV-coinfection was independently associated to treatment failure, and led to a significantly slower HCV-RNA clearance.

Abstract: Presented here is the first report of clinical reactivation of hepatitis B virus (HBV) in an HIV-infected patient who previously had anti-HBc as the only serological marker of past infection (anti-HBc alone). Reactivation occurred after lamivudine was removed from the patient's antiretroviral treatment regimen due to lack of virological response. HIV-infected patients frequently present anti-HBc alone, and in some cases this serological profile is associated with occult HBV infection. The current case demonstrates the importance of ruling out the possibility of occult infection in this patient group.

Abstract: INTRODUCTION: The aims of this study were to estimate the prevalence of HIV and hepatitis virus coinfection in the Spanish population and to determine the percentage of patients who are candidates for chronic hepatitis C virus (HCV) treatment and liver transplantation within this population. METHODS: A cross-sectional study was performed in 2002 in two Spanish populations of HIV-infected patients: 1,260 patients from 39 centers throughout Spain (P1) and 1,560 patients from three tertiary teaching hospitals in Madrid (P2). RESULTS: The following hepatitis A virus (HAV), hepatitis B virus (HBV) and HCV serological prevalence were found in the P1 and P2 groups, respectively: HAV-IgG antibodies: 74% and 78%; HBsAg1: 4.9% and 4.8%; HBsAg-, anti-HBc1, anti-HBs1: 39% and 39%; HBsAg-, anti-HBc1, anti-HBs-: 25% and 31%; HBsAg-, anti-HBc-, anti-HBs1: 7% and 8%; HBsAg-, anti-HBc-, anti-HBs-: 22% and 16%. Anti-HCV1: 61% and 65%, respectively. Of the patients with positive HCV serology, 88.8% and 84.6% of each group were positive for HCV-RNA by polymerase chain reaction. Multiple coinfections with hepatitis viruses were found in 3.2% and 2.8%, respectively; of these, 70% and 78% had coinfection with HBV, HCV and HDV. Liver cirrhosis was found in 5.8% and 9.6% of the patients coinfected with HIV and HCV, respectively. Liver transplant was indicated in approximately one out of every six coinfected patients with liver cirrhosis. The 43 and 37% of the HCV coinfected patients were good candidates for anti-HCV treatment, but only 14% and 15% of patients had initiated it. CONCLUSIONS: A high percentage of HIV-infected patients in Spain were coinfected with hepatitis viruses, especially HCV. The number of possible candidates for liver transplantation is rising and could increase in the next few years. In the future, greater efforts to treat HIV-and hepatitis virus-coinfected patients will be required.

Abstract: BACKGROUND: Coinfection with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) is a known risk factor for hepatotoxicity in patients receiving highly active antiretroviral therapy (HAART). The aim of this study was to evaluate the role of HCV-related liver fibrosis in HAART-associated hepatotoxicity. METHODS: In a prospective study involving 107 patients who underwent liver biopsy, fibrosis was graded according 5 stages, from F0 (no fibrosis) to F4 (cirrhosis). Hepatotoxicity was defined as an increase in levels of aspartate aminotransferase and alanine aminotransferase to >5 times the upper limit of normal, or a >3.5-fold increase if baseline levels were abnormal. The incidence of hepatotoxicity was compared with liver fibrosis stage and with time and composition of HAART. RESULTS: Overall, 27 patients (25%) had hepatotoxic events (5.1 events/100 person-years of therapy). The incidence was greater for patients with stage F3 or F4 fibrosis (38%) than for those with stage F1 or F2 fibrosis (15%; 7.6 vs. 3 events/100 person-years; relative risk, 2.75; 95% confidence interval, 1.08-6.97; P=.013). Duration of HCV infection, duration of HAART, diagnosis of acquired immunodeficiency syndrome, HCV load, HCV genotype, and nadir CD4(+) cell count did not affect the risk of hepatotoxicity. Of the 86 patients who received nonnucleoside reverse-transcriptase inhibitors (NNRTIs), 11 (13%) developed liver toxicity. In these patients, fibrosis stages F1 and F2 were associated with similar rates of toxicity (3 events/100 person-years for patients who received nevirapine, 3.3 events/100 person-years for those who received efavirenz, and 3.4 events/100 person-years for those who received non-NNRTIs). There was a greater incidence among patients with F3 or F4 fibrosis who received NNRTIs (11.7 events/100 person-years for patients who received nevirapine, and 8.6 events/100 person-years for those who received efavirenz), compared with those who received non-NNRTIs (4 events/100 person-years). CONCLUSIONS: HAART-associated hepatotoxicity correlates with liver histological stage in patients coinfected with HIV and HCV. There was no difference in hepatotoxicity risk for different antiretroviral therapies in patients with mild-to-moderate fibrosis.

Abstract: Liver transplantation is being evaluated as a therapeutic option for human immunodeficiency virus (HIV)-infected patients with end-stage liver disease, but experience is still scarce. We describe the outcome of 4 HIV-infected patients who underwent liver transplantation in our hospital between July 2002 and April 2003. HIV-infected liver transplant recipients meet the same standard criteria for transplantation as do HIV-negative candidates. In addition, HIV infected persons are required to have a CD4 T-cell count greater than 100/mL (CD4 T-cells are targets for HIV infection). Immunosuppressive regimens, perioperative surgical prophylaxis, and prophylaxis for opportunistic infections are standard in the Liver Transplantation Unit in our hospital. Four patients, including 3 former intravenous drug users, received a liver transplant (2 from deceased donors and 2 from living donors), with a median follow-up of 510 days. Three patients (75%) are alive, with 1 death occurring 17 months posttransplantation in a patient who developed fibrosing cholestatic hepatitis. Rejection occurred in 1 patient, and was managed with no complications. Hepatitis C virus (HCV) recurrence occurred in 3 patients. HIV-infection has remained under control with antiretroviral treatment. A combination of 3 nucleoside analogs was used in 3 patients, with no need for drug adjustments. No opportunistic infections or other significant infectious complications developed. In conclusion, orthotopic liver transplantation seems a safe therapeutic option in the short term for HIV-infected persons with end stage liver disease, including patients with a history of drug abuse. If indicated, an antiretroviral regimen consisting of 3 nucleosides could be used to avoid interactions with immunosuppressive drugs.

Abstract: Partial splenic embolization (PSE), a non-surgical treatment for hypersplenism, has also been reported to improve hepatic function. As severe thrombocytopaenia or leukopaenia contraindicate the use of combined therapy with pegylated interferons (PEG-IFNs) and ribavirin (RBV) in HCV-related cirrhosis, we evaluated, from July 2002 to October 2003, the safety and effectiveness of PSE as a procedure to allow therapy for HCV in three Child-Pugh class B cirrhotic patients with hypersplenism and HIV co-infection. HCV genotypes were 1b (n=2) and 3a (n=1). Severe thrombocytopaenia (in all) and leukopaenia (in two) precluded therapy for HCV. PSE was successfully performed in all with a mean infarcted area of 80%, leading to a significant increase in platelet and leukocyte counts that allowed therapy with weight-adjusted RBV and PEG-IFN-alpha-2b (patients 1 and 3) or 180 microg of PEG-IFN-alpha-2a (patient 2) 8 weeks after the procedure. Moderate pain, well controlled with conservative measures, followed PSE in 100% of cases, but during follow-up (mean 422 days) there were no infectious complications or liver decompensation episodes. Although preliminary, these results suggest the potential role of PSE in HIV/HCV-cirrhotic subjects with hypersplenism as a procedure to allow the use of combined PEG-IFN and RBV.

Abstract: We evaluated the role of liver biopsy in the management of chronic hepatitis C in HIV-infected persons. Patients included had abnormal alanine transaminase (ALT) levels, detectable HCV RNA, and an interpretable liver biopsy. Demographic, epidemiologic, clinical, laboratory, histological, and therapeutic data were recorded in all patients. We also registered the clinical diagnosis of cirrhosis (previous to biopsy) and whether the biopsy result deferred the decision of initiating therapy. During the 33-month duration of the study, 112 patients were included. The degree of fibrosis in liver biopsies was none or mild (F0 or F1) in 47 patients (42%) and was significant or severe in 65 (58%). Seventeen patients (15%) had histological cirrhosis. By logistic regression analysis, only portal hypertension (odds ratio [95% confidence interval], 5.3 [1.05-25.9], P = 0.04) was independently associated with significant fibrosis. Overall, cirrhosis was predicted before biopsy in 29 patients (26%) by the caregiving physician, but only 8 of these were confirmed histologically. The clinical prediction of cirrhosis before biopsy had a sensitivity of 47%, a specificity of 78%, a positive predictive value of 28%, and a negative predictive value of 89%. Histological findings changed the decision to initiate HCV therapy in 19 patients (17%) because of little or no fibrosis. Liver biopsy is a useful tool in the management of HCV-HIV-coinfected persons. In addition to allowing grading and staging of the disease far better than any other method or combination of methods, it is important for making management decisions for patients coinfected with HCV and HIV.

Abstract: BACKGROUND: Hepatitis C virus (HCV) and HIV coinfection constitutes an important epidemiological and clinical problem. We evaluated the safety and efficacy of Pegylated interferon alpha2b (Peg-IFN) and a fixed dose of ribavirin in the treatment of chronic hepatitis C in HIV coinfection. METHODS: Open, prospective study in HCV-HIV coinfected patients with persistently elevated alanine aminotransferase (ALT) levels and a liver biopsy showing either portal or bridging fibrosis. Therapy included Peg-IFN (50 micro g weekly) with ribavirin 800 mg for 48 weeks. The primary end point was sustained virological response (SVR). Univariate and multivariate analyses were performed to determine factors associated with response. RESULTS: By intent-to-treat analysis, 11 of 35 patients (31%) reached SVR. SVR was significantly better for genotypes 2/3 than for genotype 1 (54% versus 21%; P < 0.05). By multivariate logistic regression analysis, only a non-1 genotype was an independent factor for SVR [odds ratio (OR), 6; 95% confidence interval (CI), 1.1-31.7; P < 0.005]. A decrease of at least 1.5 log10 HCV RNA at week 12 of therapy was highly predictive of SVR (OR, 49.9; 95% CI, 4.9-508.2; P < 0.001). Most patients developed adverse events, although only six patients (17%) discontinued treatment due to toxicity. CONCLUSIONS: The combination of low doses of Peg-IFN plus a fixed dose of ribavirin resulted in a rate of SVR similar to that obtained with higher doses of the drugs in HIV-infected patients and lower than those obtained in non-HIV patients. Response at week 12 may be useful to help guide therapy in HCV-HIV co-infected patients.

Abstract: BACKGROUND: Nucleoside analogues may induce mitochondrial toxicity, particularly didanosine. Ribavirin increases didanosine exposure, which might be clinically relevant when coadministered in HIV/HCV-coinfected patients. OBJECTIVE: To evaluate, among 89 patients receiving highly active antiretroviral therapy (HAART) and therapy for chronic hepatitis C, clinically relevant mitochondrial toxicity in those treated with concomitant ribavirin and didanosine (n=35, 39%). METHODS: From January 2000 to July 2002 longitudinal analysis of the incidence and clinical course of didanosine-related hyperamylasaemia, pancreatitis, hyperlactataemia/lactic acidosis or neuropathy. Risk factors were evaluated using univariate and multivariate Cox's proportional hazards model. RESULTS: Among 35 patients who received concomitant didanosine (400 mg/day in 86%) and ribavirin (> or = 10 mg/kg/day in 91%), 20 (57%) developed one or more adverse events after a mean of 87 days. Most frequent laboratory abnormalities were hyperamylasaemia (18 patients, 51%) and hyperlactataemia (eight patients, 23%). Acute pancreatitis and symptomatic hyperlactataemia developed in 10 (28%) and six (17%) patients, respectively. Two patients (6%) with pancreatitis and severe lactic acidosis died; the other patients recovered uneventfully despite continuation of anti-HCV therapy in 83% after didanosine withdrawal in 40%. In the Cox's model higher baseline amylase levels (HR: 1.04, 95% CI: 1.02-1.06, P=0.001) and three nucleoside reverse transcriptase inhibitor-based HAART (HR: 5.3, 95% CI: 1.73-16.24, P=0.003) were significantly associated to toxicity. CONCLUSIONS: The coadministration of didanosine and ribavirin should be avoided in HIV/HCV-coinfected patients, due to a high rate of clinically significant toxicity, particularly in triple nucleoside-based HAART. Amylase levels should be strictly monitored, especially if elevated at baseline.

Abstract: A study was performed in 10 European health care centers in which 914 patients coinfected with hepatitis C virus (HCV) and human immunodeficiency virus (HIV) who had elevated serum alanine aminotransferase (ALT) levels underwent liver biopsy during the period of 1992 through 2002. Overall, the METAVIR liver fibrosis stage was F0 in 10% of patients, F1 in 33%, F2 in 22%, F3 in 22%, and F4 in 13%. Predictors of severe liver fibrosis (METAVIR stage, F3 or F4) in multivariate analysis were age of >35 years (odds ratio [OR], 2.95; 95% confidence interval [CI], 2.08-4.18), alcohol consumption of >50 g/day (OR, 1.61; 95% CI, 1.1-2.35), and CD4+ T cell count of <500 cells/mm3 (OR, 1.43; 95% CI, 1.03-1.98). Forty-six percent of patients aged >40 years had severe liver fibrosis, compared with 15% of subjects aged <30 years. The use of antiretroviral therapy was not associated with the severity of liver fibrosis. In summary, severe liver fibrosis is frequently found in HCV-HIV-coinfected patients with elevated serum ALT levels, and its severity increases significantly with age. The rate of complications due to end-stage liver disease will inevitably increase in this population, for whom anti-HCV therapy should be considered a priority.
