RESUMEN

The aim of this multi-centre French retrospective study was to identify severe, i.e. crusted and profuse, scabies patients. Records were retrieved from 22 Dermatology or Infectious Diseases departments in the Ile-de-France from January 2009 to January 2015 to characterize epidemiology, demography, diagnosis, contributing factors, treatment features, and outcomes in severe scabies. A total of 95 inpatients (57 crusted and 38 profuse) were included. A higher number of cases was observed among elderly patients (>75 years), mostly living in institutions. Thirteen patients (13.6%) reported a history of previously treated scabies. Sixty-three patients (66.3%) had been seen by a previous practitioner for the current episode (up to 8 previous visits). Initial misdiagnosis (e.g. eczema, prurigo, drug-related eruptions, psoriasis) was documented in 41 patients (43.1%). Fifty-eight patients (61%) had already received 1 or more previous treatments for their current episode. Forty percent received corticosteroids or acitretin for an initial diagnosis of eczema or psoriasis. Median time from the onset of symptoms to the diagnosis of severe scabies was 3 months (range 0.3-22). Itch was present in all patients at diagnosis. Most patients (n=84, 88.4%) had comorbidities. Diagnostic and therapeutic approaches varied. Complications occurred in 11.5% of cases. To date, there is no consensus for diagnosis and treatment, and future standardization of is required for optimal management.

RESUMEN

BACKGROUND & AIMS: There is little data available on the use of new oral direct-acting antiviral (DAA) regimens to treat human immunodeficiency virus and hepatitis C virus (HIV/HCV) co-infected patients in real-life settings. Here, the efficacy and safety of all-oral DAA-based regimens in HIV/HCV-co-infected patients enrolled in the French nationwide ANRS CO13 HEPAVIH observational cohort are reported. METHODS: HIV/HCV-co-infected patients enrolled in the ANRS CO13 HEPAVIH observational cohort were included if they began an all-oral DAA-based regimen before 1st May 2015 (12-week regimens) or 1st February 2015 (24-week regimens). Treatment success (SVR12) was defined by undetectable HCV-RNA 12weeks after treatment cessation. Exact logistic regression analysis was used to identify factors associated with SVR12. RESULTS: A total of 323 patients (74% men) with a median age of 53years were included, 99% of whom were on combination antiretroviral therapy (cART). HIV RNA load was <50 copies/ml in 88% of patients; median CD4 cell count was 540/mm3; 60% of patients were cirrhotic; 68% had previously received unsuccessful anti-HCV treatment. cART was protease inhibitor (PI)-based in 23%, non-nucleoside reverse transcriptase inhibitor (NNRTI)-based in 15%, and integrase inhibitor (II)-based in 38%, while 24% of patients received other regimens. The SVR12 rate was 93.5% overall (95% confidence interval [CI]: 90.2-95.9), 93.3% (88.8-96.4) in patients with cirrhosis and 93.8% (88.1-97.3) in patients without cirrhosis. The SVR12 rates were 93.1% (84.5-97.7), 91.8% (80.4-97.7) and 95.8% (90.5-98.6) respectively, in patients receiving PI-based, NNRTI-based and II-based cART. In adjusted analysis, SVR12 was not associated with HIV RNA load, the cART regimen, cirrhosis, prior anti-HCV treatment, the duration of anti-HCV therapy, or ribavirin use. The most common adverse effects were fatigue and digestive disorders. CONCLUSIONS: New all-oral DAA regimens were well-tolerated and yielded high SVR12 rates in HIV/HCV-co-infected patients. LAY SUMMARY: We evaluated efficacy and safety of all-oral DAA regimens in a large French nationwide observational cohort study of HIV/HCV co-infected patients. Sustained virological response 12weeks after treatment cessation was 93.5% overall. The all-oral DAA regimens were well-tolerated and most common adverse effects were fatigue and digestive disorders.

RESUMEN

BACKGROUND: Human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients with cirrhosis have long been considered to be difficult to treat, and real-life efficacy and tolerance data with all-oral direct-acting antiviral (DAA) combinations in these patients are scarce. METHODS: Cirrhotic HIV/HCV-coinfected patients enrolled in the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) CO13 HEPAVIH cohort initiating an all-oral DAA regimen were consecutively included. A negative HCV RNA result at 12 weeks of follow-up or thereafter was assumed as a sustained virologic response (SVR12). Adjusted exact logistic regression was used to study factors associated with treatment outcome. RESULTS: We included 189 patients who initiated an all-oral DAA regimen with the following characteristics: median age 53.2 years; 74.6% male; Centers for Disease Control and Prevention classification A/B/C: 37%/31%/32%; Child-Pugh class A/B/C: 91%/8%/1%; 87% with HIV RNA <50 copies/mL; 99% on antiretrovirals; median CD4 count: 489 cells/µL; HCV treatment naive 29%; HCV genotype 1/2/3/4: 58%/4%/17%/21%. Sofosbuvir (SOF) + daclatasvir ± ribavirin (RBV) was used in 123 patients, SOF + RBV in 30, SOF + simeprevir in 11, and SOF + ledipasvir in 23. An SVR12 was reported in 93.1% of the patients (95% confidence interval, 88.5%-96.3%). In adjusted analyses, no difference was found between 12 or 24 weeks of treatment, in patients receiving RBV or not, and in treatment-naive vs experienced patients. Premature stop of DAA was reported for 8 patients. One patient died during treatment (unknown cause), and 12 other patients developed liver-related events. CONCLUSIONS: In this prospective real-life cohort, all-oral DAA regimens were well tolerated and associated with a high virologic efficacy in cirrhotic HIV/HCV-coinfected patients. This should not alleviate the surveillance for liver-related events in these patients.

RESUMEN

Here, we characterized the first OXA-72-producing Acinetobacter baumannii isolate (designated MAL) recovered from a urine sample from a Serbian patient. Antimicrobial susceptibility testing, plasmid analysis, and whole-genome sequencing (WGS) were performed to fully characterize the resistome of the A. baumannii MAL clinical isolate. The isolate was multidrug resistant and remained susceptible only to colistin and tigecycline. PCR analysis revealed the presence of the carbapenemase OXA-72, an OXA-40 variant. Extraction by the Kieser method revealed the presence of two plasmids, and one of these, a ca. 10-kb plasmid, harbored the blaOXA-72 gene. WGS revealed 206 contigs corresponding to a genome of 3.9 Mbp in size with a G+C content of 38.8%. The isolate belonged to sequence type 492 and to worldwide clone II (WWCII). Naturally occurring ß-lactamase-encoding genes (blaADC-25 and blaOXA-66) were also identified. Aminoglycoside resistance genes encoding one aminoglycoside adenyltransferase (aadA2), three aminoglycoside phosphatases (strA, strB, aphA6), and one 16S RNA methylase (armA) conferring resistance to all aminoglycosides were identified. Resistance to fluoroquinolones was likely due to mutations in gyrA, parC, and parE Of note, the resistome matched perfectly with the antibiotic susceptibility testing results.

RESUMEN

BACKGROUND: Multidrug-resistant Enterobacteriaceae (MRE) are widespread in the community, especially in tropical regions. Travelers are at risk of acquiring MRE in these regions, but the precise extent of the problem is not known. METHODS: From February 2012 to April 2013, travelers attending 6 international vaccination centers in the Paris area prior to traveling to tropical regions were asked to provide a fecal sample before and after their trip. Those found to have acquired MRE were asked to send fecal samples 1, 2, 3, 6, and 12 months after their return, or until MRE was no longer detected. The fecal relative abundance of MRE among all Enterobacteriaceae was determined in each carrier. RESULTS: Among 824 participating travelers, 574 provided fecal samples before and after travel and were not MRE carriers before departure. Of these, 292 (50.9%) acquired an average of 1.8 MRE. Three travelers (0.5%) acquired carbapenemase-producing Enterobacteriaceae. The acquisition rate was higher in Asia (142/196 [72.4%]) than in sub-Saharan Africa (93/195 [47.7%]) or Latin America (57/183 [31.1%]). MRE acquisition was associated with the type of travel, diarrhea, and exposure to ß-lactams during the travel. Three months after return, 4.7% of the travelers carried MRE. Carriage lasted longer in travelers returning from Asia and in travelers with a high relative abundance of MRE at return. CONCLUSIONS: MRE acquisition is very frequent among travelers to tropical regions. Travel to these regions should be considered a risk factor of MRE carriage during the first 3 months after return, but not beyond. CLINICAL TRIALS REGISTRATION: NCT01526187.

RESUMEN

BACKGROUND & AIMS: The aim of this study was to analyse the safety and efficacy of the PegIFNα/ribavirin/protease inhibitor combination in severe and/or refractory hepatitis C virus (HCV)-mixed cryoglobulinemia (MC) vasculitis. METHODS: This prospective cohort study included 30 patients (median age 59 years [53-66] and 57% of women) with HCV-MC vasculitis. PegIFNα/ribavirin (for 48 weeks) was associated with telaprevir (375 mg three times daily, for 12 weeks, [n = 17]) or boceprevir (800 mg three times daily, for 44 weeks, (n = 13]). RESULTS: Twenty three patients (76.7%) were non-responders to previous antiviral therapy. At week 72, twenty patients (66.7%) were complete clinical and sustained virological responders. The cryoglobulin level decreased from 0.45 to 0 g/L (p<0.0001) and the C4 level increased from 0.09 to 0.14 g/L (p = 0.017). Complete clinical responders had a higher frequency of purpura (16/20 [80%] vs. 4/10 [40%], p = 0.045), and a trend towards lower frequency of neuropathy (9/20 (45%) vs. 8/10 [80%], p = 0.12) compared with partial responders. Serious adverse events occurred in 14 patients (46.6%) during the 72 weeks of follow-up. Twenty eight patients (93.3%) received erythropoietin, 14 (46.6%) had red blood cell transfusion and 2 (6.6%) received granulocyte stimulating agent. The baseline factors associated with serious adverse events included liver fibrosis (p = 0.045) and a low platelet count (p = 0.021). CONCLUSIONS: The PegIFNα/ribavirin/protease inhibitor combination is highly effective in severe and/or refractory HCV-MC at the cost of frequent side effects. Baseline platelet count and liver fibrosis are useful in guiding treatment decisions.

RESUMEN

BACKGROUND: The end-stage LIVER disease and RALtegravir-Agence Nationale de Recherche sur le Sida et les hépatites (LIVERAL-ANRS) 148 study aimed to evaluate the safety, efficacy, and pharmacokinetic parameters of raltegravir (RAL) in human immunodeficiency virus (HIV)-infected patients with end-stage liver disease (ESLD) (substudy 1) and to assess the lack of pharmacokinetic interaction between RAL and the immunosuppressive regimen introduced after liver transplant (substudy 2). METHODS: All patients received 400 mg RAL twice daily plus 2 nucleoside reverse transcriptase inhibitors. Liver function and immunovirological parameters were monitored throughout the study. Serial blood samples were drawn to explore RAL pharmacokinetics. Plasma concentrations of protein unbound, total RAL, and RAL glucuronide were determined by liquid chromatography-tandem mass spectrometry. RESULTS: Ten patients with ESLD were analyzed in substudy 1. Despite an increased RAL exposure, RAL was well tolerated in all patients and no patient had to stop RAL therapy because of adverse events. Four patients were analyzed in substudy 2. No pharmacokinetic interaction was observed between cyclosporine, mycophenolic acid, and RAL. RAL tolerability was excellent; there were no episodes of acute rejection or opportunistic infection. HIV-RNA levels remained controlled and CD4 cell counts remained stable in all patients throughout the study. CONCLUSIONS: The results of the substudy 1 support RAL administration to patients with ESLD. Substudy 2 assesses the safety, tolerability, and efficacy of RAL therapy in HIV-infected patients after liver transplant. RAL might be recommended as a suitable antiretroviral therapy in HIV-infected patients undergoing liver transplant.

RESUMEN

BACKGROUND: Retreatment with pegylated interferon (peg-IFN) and ribavirin (RBV) results in poor sustained virological response (SVR) rates in human immunodeficiency virus (HIV)/hepatitis C virus (HCV)-coinfected patients. There are limited data regarding the use of telaprevir plus peg-IFN/RBV in this population. METHODS: HIV type 1-infected patients who previously failed ≥12 weeks of peg-IFN/RBV for HCV genotype 1 coinfection were enrolled in a single-arm, phase 2 trial. Patients with cirrhosis and previous null response were excluded. Authorized antiretrovirals were tenofovir, emtricitabine, efavirenz, atazanavir, and raltegravir. All patients received peg-IFN alfa-2a (180 µg/week) plus RBV (1000-1200 mg/day) for 4 weeks, followed by telaprevir (750 mg or 1125 mg every 8 hours with efavirenz) plus peg-IFN/RBV for 12 weeks and peg-IFN/RBV for 32-56 weeks according to virological response at week 8. The primary endpoint was the SVR rate at 24 weeks after the end of treatment (SVR24). RESULTS: Sixty-nine patients started treatment; SVR24 was achieved in 55 (80% [95% confidence interval, 68%-88%). SVR24 was not influenced by baseline fibrosis stage, IL28B genotype, antiretroviral regimen, HCV subtype, CD4 cell count, previous response to HCV treatment, HCV RNA level, or HCV RNA decline at week 4. HCV treatment was discontinued for adverse events (AEs) in 20% of patients, including cutaneous (4%), psychiatric (4%), hematological (6%), and other AEs (6%). Peg-IFN or RBV dose reduction was required in 23% and 43% of patients, respectively. Seventy percent of patients required erythropoietin, blood transfusions, or RBV dose reduction for anemia. Two patients died during the study. No HIV breakthrough was observed. CONCLUSIONS: Despite a high discontinuation rate related to toxicity, a substantial proportion of treatment-experienced HIV-coinfected patients achieved SVR24 with a telaprevir-based regimen. Clinical Trials Registration. NCT01332955.

RESUMEN

BACKGROUND & AIMS: To determine the characteristics of hepatitis C (HCV)- infected patients in 2010 and compare this survey with those reported in 1995 and 2001. PATIENTS AND METHODS: Observational multicentre study conducted in 2010 in French internal medicine, infectious diseases and hepatology departments. RESULTS: A total of 1621 HCV infected patients (mean age 50.1 ± 10.7 years; sex ratio M/F 1.8; genotype 1: 55.7%) were included. Of these, 910 (56.1%) were HIV­HCV co-infected, 463 (40.4%) were asymptomatic and 184 (16.1%) had cirrhosis at inclusion in this study. Positive viraemia was found in 1,025 patients (65.5%) at inclusion in this study. A complete pretreatment evaluation including investigation for HCV RNA, genotype determination and liver fibrosis was performed in 96.5, 80.5 and 68.7% of the 1,621 patients respectively. Previous and ongoing HCV treatments were noted in 49.6% and 20.1% of patients respectively. A sustained virological response (SVR) was observed in 271/801 (38.3%) patients, i.e. 44.1% and 30.7% in co-infected and mono-infected patients respectively. Cirrhosis was more frequent in the 2010 than in the 2001 and 1995 surveys (16.1% vs. 10.4% and 7.4% respectively; P < 0.0001). A complete pretreatment evaluation was performed in 57.9% and 50.9% of patients in 2010 and 2001 (P < 0.0001). Liver fibrosis evaluation was more frequent in 2010 than in the 2001 and 1995 surveys (68.7% vs. 62.7% and 28.7%, respectively, P < 0.0001). CONCLUSION: The care of HCV-infected patients has changed significantly in 'real life' through an improvement of pretreatment evaluation before the antiviral introduction and the increased use of antivirals. New HCV therapy combinations including protease inhibitors are warranted to increase the SVR rate.

RESUMEN

BACKGROUND & AIMS: Compared to HCV-mono-infected patients, hepatocellular carcinoma (HCC) occurs at younger age in HIV/HCV-co-infected patients, is markedly more advanced at diagnosis, is less amenable to curative treatment, and has a more severe outcome. The aim of this study was to identify factors predictive of HCC occurrence in a large cohort of HIV/HCV-co-infected patients with cirrhosis. METHODS: This study involved 244 HIV/HCV-co-infected patients included in the ANRS CO13 HEPAVIH cohort, who had HCV-related cirrhosis (clinically or histologically proven cirrhosis, or liver stiffness ≥12.5 kPa) and no signs of HCC at baseline. Cox proportional hazards models were used to identify factors associated with HCC occurrence. RESULTS: During a median follow-up of 2.6 (IQR, 1.8-3.5) years, 21 patients (8.6%) developed HCC. Diagnosis of HCC was based on histology in 5 patients (24%) and non-invasive criteria in 16 patients (76%). In univariate analyses, the following factors were related to HCC occurrence: age, previous cirrhosis decompensation, a HOMA value >3.8 (patients with treated diabetes were excluded from the HOMA calculation), a lower platelet count, a lower prothrombin level, and higher alpha-fetoprotein levels. The HOMA value was >3.8 at baseline in 66.7% of patients who developed HCC and in 35.3% of the remaining patients (p=0.016). In multivariate analysis, age over 50 years (adjusted RR 3.2, 95% CI 1.2-9.0; p=0.02) and a HOMA value >3.8 (adjusted RR 3.4, 95% CI 1.1-10.3; p=0.03) remained significantly associated with HCC occurrence. CONCLUSIONS: As in HCV-mono-infected patients with HCV-related cirrhosis, insulin resistance appears to play a key role in HCC occurrence in HCV/HIV-co-infected patients with cirrhosis. This finding calls for specific screening strategies for patients with a particularly high risk of developing HCC.

RESUMEN

To determine the correlates of immune recovery from active human CMV (HCMV) disease, we compared the antigenic repertoire, diversity, magnitude, and differentiation of HCMV-specific CD8+ T cells in HIV-HCMV coinfected subjects with no, cured, or active HCMV disease and in healthy HIV-negative HCMV-positive controls. ELISPOT-IFN-gamma assays using peptide pools spanning the pp65 and immediate early 1 (IE1) HCMV proteins showed that HCMV-specific CD8+ T cells had a significantly broader antigenic repertoire and greater diversity in HIV-positive patients controlling HCMV replication than in those with active HCMV disease, but the magnitude of the CD8 T cell response did not differ between the different groups. HCMV-specific T cells mainly were focused against IE1 during the short-term recovery from retinitis, and switched toward pp65 during long-term recovery. HCMV-specific T cells displaying an "early" (CD8+CD27+CD28+) and "intermediate" (CD8+CD27-CD28+) differentiation phenotype were increased significantly during long-term recovery compared with other HIV-positive patients and were nearly undetectable during active HCMV disease. HCMV-specific T cells with a "late" (CD8+CD27-28-) differentiation phenotype predominated in all cases. Therefore, restoration of immune protection against HCMV after active HCMV disease in immunodeficient individuals is associated with enlarged repertoire and diversity, and with early differentiation of virus-specific CD8+ T cells, thus defining immune correlates of protection against diseases caused by persistent viruses.

RESUMEN

BACKGROUND: In France, it is estimated that 24% of HIV-infected patients are also infected with HCV. Longitudinal studies addressing clinical and public health questions related to HIV-HCV co-infection (HIV-HCV clinical progression and its determinants including genetic dimension, patients' experience with these two diseases and their treatments) are limited. The ANRS CO 13 HEPAVIH cohort was set up to explore these critical questions.To describe the cohort aims and organization, monitoring and data collection procedures, baseline characteristics, as well as follow-up findings to date. METHODS: Inclusion criteria in the cohort were: age > 18 years, HIV-1 infection, chronic hepatitis C virus (HCV) infection or sustained response to HCV treatment. A standardized medical questionnaire collecting socio-demographic, clinical, biological, therapeutic, histological, ultrasound and endoscopic data is administered at enrollment, then every six months for cirrhotic patients or yearly for non-cirrhotic patients. Also, a self-administered questionnaire documenting socio-behavioral data and adherence to HIV and/or HCV treatments is administered at enrollment and yearly thereafter. RESULTS: A total of 1,175 patients were included from January 2006 to December 2008. Their median age at enrollment was 45 years and 70.2% were male. The median CD4 cell count was 442 (IQR: 304-633) cells/µl and HIV RNA plasma viral load was undetectable in 68.8%. Most participants (71.6%) were on HAART. Among the 1,048 HIV-HCV chronically co-infected patients, HCV genotype 1 was predominant (56%) and cirrhosis was present in 25%. As of January, 2010, after a median follow-up of 16.7 months (IQR: 11.3-25.3), 13 new cases of decompensated cirrhosis, nine hepatocellular carcinomas and 20 HCV-related deaths were reported, resulting in a cumulative HCV-related severe event rate of 1.9/100 person-years (95% CI: 1.3-2.5). The rate of HCV-related severe events was higher in cirrhotic patients and those with a low CD4 cells count, but did not differ according to sex, age, alcohol consumption, CDC clinical stage or HCV status. CONCLUSION: The ANRS CO 13 HEPAVIH is a nation-wide cohort using a large network of HIV treatment, infectious diseases and internal medicine clinics in France, and thus is highly representative of the French population living with these two viruses and in care.

RESUMEN

We describe a patient with human immunodeficiency virus (HIV) and hepatitis C virus coinfection who experienced recurrent episodes of acute HIV meningoencephalitis. The addition of etravirine to the therapeutic regimen completely resolved symptoms, and HIV was no longer detected in cerebrospinal spinal fluid specimens. Etravirine has a satisfactory safety profile and, in this case, was a durable alternative therapy for HIV meningoencephalitis.

RESUMEN

BACKGROUND/AIMS: Liver transplantation (LT) in immune-suppressed human immunodeficiency virus (HIV) and hepatitis C virus (HCV) coinfected patients is feasible but raises questions regarding the severity of HCV recurrence on the liver graft and preservation of immune function. We investigated whether LT is deleterious to the immune system. METHODS: Fourteen HIV-HCV coinfected patients (HIV viral load [VL] <50 copies/ml; median CD4 count of 276/mm(3) pretransplantation) were grafted for HCV-cirrhosis and followed over 2 years. Nine patients received anti-HCV therapy post-transplantation. HCV and HIV VLs and degree of acute and chronic hepatitis were monitored. Peripheral blood T-cell phenotypes and interferon-gamma (IFN-gamma) immune responses against opportunistic pathogens, HCV, and HIV-1 p24 were evaluated. RESULTS: Median HCV VLs, CD4 counts, T-cell subsets, and IFN-gamma-producing T-cell frequencies against opportunistic pathogens and HIV-1 p24 did not change over time. HCV-specific T cells were observed ex vivo in two patients pretransplantation and in two others post-transplantation. HCV-specific in vitro amplification enabled the detection of HCV-specific IFN-gamma-producing responses in three further patients post-transplantation. Anti-HCV responses were observed independently of anti-HCV therapy and were undetectable in patients with severe hepatitis or liver fibrosis. CONCLUSIONS: These results demonstrate that LT in HIV-HCV coinfected patients is not deleterious to the immune system and does not alter immune responses directed against HCV, HIV, or opportunistic pathogens.

RESUMEN

The aim of this study was to evaluate the impact of an enfuvirtide-based antiretroviral (ARV) regimen on the management of immunosuppression and follow-up in hepatitis C virus (HCV)/hepatitis B virus (HBV)/human immunodeficiency virus (HIV)-coinfected liver transplant patients in comparison with a lopinavir/ritonavir-based ARV regimen. Tacrolimus and cyclosporine trough concentrations were determined at a steady state during 3 periods: after liver transplantation without ARV treatment (period 1), at the time of ARV reintroduction (period 2), and 2 to 3 months after liver transplantation (period 3). The findings for 22 HIV-coinfected patients were compared (18 with HCV and 4 with HBV); 11 patients were treated with enfuvirtide and were matched with 11 lopinavir/ritonavir-exposed patients. During period 1, tacrolimus and cyclosporine A doses were 8 and 600 mg/day, respectively, and the trough concentrations were within the therapeutic range in both groups. In period 2, the addition of lopinavir/ritonavir to the immunosuppressant regimen enabled a reduction in the dose of immunosuppressants required to maintain trough concentrations within the therapeutic range (to 0.3 mg/day for tacrolimus and 75 mg/day for cyclosporine). Immunosuppressant doses were not modified by the reintroduction of enfuvirtide, there being no change in the mean trough concentrations over the 3 periods. CD4 cell counts remained at about 200 cells/mm3. The HIV RNA viral load remained undetectable. Both groups displayed signs of mild cytolysis and cholestasis due to the recurrence of HCV, whereas no renal insufficiency was observed. Enfuvirtide is an attractive alternative to standard ARV therapy, facilitating the management of drug-drug interactions shortly after liver transplantation. Moreover, the lack of liver toxicity renders this drug valuable in the event of a severe HCV recurrence.

RESUMEN

UNLABELLED: Liver transplantation in patients coinfected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV) is a recent indication. In a single center, we have compared the survival and severity of recurrent HCV infection after liver transplantation in HIV-HCV-coinfected and HCV-monoinfected patients. Seventy-nine patients receiving a first liver graft for HCV-related liver disease between 1999 and 2005 were included. Among them, 35 had highly active antiretroviral therapy-controlled HIV infection. All patients were monitored for HCV viral load and liver histology during the posttransplantation course. Coinfected patients were younger (43 +/- 6 versus 55 +/- 8 years, P < 0.0001) and had a higher Model for End-Stage Liver Disease (MELD) score (18.8 +/- 7.4 versus 14.8 +/- 4.7; P = 0.008). The 2-year and 5-year survival rates were 73% and 51% and 91% and 81% in coinfected patients and monoinfected patients, respectively (log-rank P = 0.004). Under multivariate Cox analysis, survival was related only to the MELD score (P = 0.03; risk ratio, 1.08; 95% confidence interval, 1.01, 1.15). Using the Kaplan-Meier method, the progression to fibrosis >or= F2 was significantly higher in the coinfected group (P < 0.0001). CONCLUSION: The results of liver transplantation in HIV-HCV-coinfected patients were satisfactory in terms of survival benefit. Earlier referral of these patients to a liver transplant unit, the use of new drugs effective against HCV, and an avoidance of drug toxicity are mandatory if we are to improve the results of this challenging indication for liver transplantation.

RESUMEN

OBJECTIVES: HIV/hepatitis C virus (HCV) co-infection leads to major complications, and noninvasive markers developed to stage liver fibrosis could be used as prognostic markers. We aimed to compare the performances of liver stiffness (LS), fibrosis-4 (FIB-4), and aspartate aminotransferase to platelet ratio index (APRI) to predict liver-related events in HIV/HCV co-infected patients. PATIENTS AND METHODS: HIV/HCV co-infected patients from the ANRS CO13 HEPAVIH cohort were included if they had LS, FIB-4, and APRI measurements done in a window of 3 months. Primary outcome was the time between inclusion and occurrence of a liver-related event. Univariable and multivariable Fine and Gray models were performed. Predictive performances were compared by the area under the receiver operating characteristic (AUROC) differences after correction of optimistic by bootstrap samples. Best cutoffs to predict liver-related events were estimated by sensitivity and specificity maximization. RESULTS: A total of 998 patients were included. Overall, 70.7% were men. Their median age was 46.8 years. According to LS value, 204 (20.4%) patients had cirrhosis. Overall, 39 patients experienced at least one liver-related event. In univariable analysis, LS AUROC curve was significantly superior to FIB-4 and APRI AUROC curves, being 87.9, 78.2, and 75.0%, respectively. After adjustment on age, CD4 levels, and insulin resistance, no differences were observed. The best cutoffs to identify patients at low or high risk of liver-related events were below 8.5, 1.00, and 0.35 and above 16.5, 4.00, and 1.75 for LS, FIB-4, and APRI, respectively. CONCLUSION: To predict HCV-related events, APRI had lower performance than LS and FIB-4. FIB-4 is as good as LS to predict HCV-related events, suggesting that it can be used for the management of HIV/HCV co-infected patients and replace LS.
