RESUMEN

OBJECTIVES: Studies evaluating the efficacy and safety of the fixed-dose combination ledipasvir (LDV)/sofosbuvir (SOF) in patients coinfected with HIV-1 and hepatitis C virus (HCV) have mainly included treatment-naïve patients without cirrhosis. We aimed to evaluate the efficacy and safety of this combination in treatment-experienced patients with and without cirrhosis. METHODS: We conducted a multicentre, open-label, double-arm, nonrandomized study in patients coinfected with HIV-1 and HCV genotype 1 with and without cirrhosis, who had good viral suppression on their antiretroviral regimens. All patients were pretreated with a first-generation NS3/4A protease inhibitor (PI) plus pegylated interferon/ribavirin. Patients received a fixed-dose combination of LDV/SOF for 12 weeks, or for 24 weeks if cirrhosis was present. The primary endpoint was a sustained virological response (SVR) 12 weeks after the end of therapy. Secondary endpoints included safety, pharmacokinetics and patient-reported outcomes. RESULTS: Of the 68 patients enrolled, 39.7% had cirrhosis. Sixty-five patients [95.6%; 95% confidence interval (CI): 87.6-99.1%; P < 0.0001] achieved an SVR, with similar rates of SVR in those with and without cirrhosis. Tolerance was satisfactory, with mainly grade 1 or 2 adverse events. Among patient-reported outcomes, only fatigue significantly decreased at the end of treatment compared with baseline [odds ratio (OR): 0.36; 95% CI: 0.14-0.96; P = 0.04]. Mean tenofovir area under the plasma concentration-time curve (AUC) at week 4 was high, with mean ± SD AUC variation between baseline and week 4 higher in cirrhotic than in noncirrhotic patients (3261.57 ± 1920.47 ng/mL vs. 1576.15 ± 911.97 ng/mL, respectively; P = 0.03). Mild proteinuria (54.4%), hypophosphataemia (50.0%), blood bicarbonate decrease (29.4%) and hypokalaemia (13.2%) were reported. The serum creatinine level was not modified. CONCLUSIONS: LDV/SOF provided a high SVR rate in PI-experienced subjects coinfected with HCV genotype 1 and HIV-1, including patients with cirrhosis.

RESUMEN

BACKGROUND: Few studies have investigated infections in human immunodeficiency virus (HIV)-infected liver transplant patients. The aim of this study was to describe the prevalence, time of onset, mortality of infectious complications, other than hepatitis C virus (HCV), and to identify risk factors for their development in a large single-center cohort of HIV-infected liver transplant patients. METHODS: We studied 109 consecutive HIV-infected patients who underwent liver transplantation (LT) between 1999 and 2010 and followed until December 2012. RESULTS: The median age was 44 years (interquartile range [IQR] 41-49), 82.6% were male, and the median follow-up was 45.7 months (IQR 14-65). The major indications for LT were HCV cirrhosis (61%) and hepatocellular carcinoma (19%). Forty patients (37%) developed at least 1 infection during the first year after LT. Twenty-eight (26%) patients had an episode of bacteremia. Five (4.6%) patients developed a cytomegalovirus infection. Fungal infections occurred in 5 (4.5%) patients. Four (3.6%) patients developed an HIV-related opportunistic infection. A total of 43 (39.4%) patients died during follow-up. Mortality related to infection occurred in 9 (7%) cases, and 20 (42.5%) patients died because of HCV recurrence. No patients died from opportunistic infections. Model for end-stage liver disease (MELD) score >17 was associated with a 2-fold higher risk (hazard ratio 1.96; 95% confidence interval 1.01-3.80) of developing infectious complications. CONCLUSIONS: Infections are not a major cause of mortality after LT in HIV patients and opportunistic infections of acquired immunodeficiency syndrome are infrequent. A MELD score >17 increased the risk of developing post-LT infectious complications. Recurrence of HCV infection remains a major cause of mortality.

RESUMEN

Amphotericin B is a powerful polyene antifungal drug used for treating systemic fungal infections and is usually administered for a short period. Side effects after prolonged use are unknown in humans. Here we report the case of a 28-year-old man suffering from chronic granulomatous disease (CGD), treated for invasive cerebral aspergillosis with liposomal amphotericin B (L-AmB) for a very long time (8 consecutive years). We describe the efficacy and safety of this treatment in the long term. Aspergillosis was kept under control as long as L-AmB therapy was maintained, but relapsed when the dose was reduced. No overt renal toxicity was noted. The patient gradually developed hepatosplenomegaly and pancytopenia. Abnormalities of bone marrow were similar to the sea-blue histiocyte syndrome. Liver biopsy showed images of nodular regenerative hyperplasia related to CGD as well as a histiocytic storage disease. We discuss the very prolonged use of L-AmB leading to the development of a lysosomal storage disease.

RESUMEN

We characterized fibrosing cholestatic hepatitis (FCH) in a large cohort of HIV/HCV co-infected patients. Between 1999 and 2008, 59 HIV infected patients were transplanted for end-stage liver disease due to HCV. Eleven patients (19%) developed FCH within a mean period of 7 months [2-27] after liver transplantation (LT). At Week 1 post-LT, the mean HCV viral load was higher in the FCH group: 6.13 log(10) IU/mL ± 1.30 versus 4.9 log(10) IU/mL ± 1.78 in the non-FCH group, p = 0.05. At the onset of acute hepatitis after LT, activity was moderate to severe in 8/11 HIV+/HCV+ patients with FCH (73%) versus 13/28 (46%) HIV+/HCV+ non-FCH (p = 0.007) patients. A complete virological response to anti-HCV therapy was observed in 2/11 (18%) patients. Survival differed significantly between the two groups (at 3 years, 67% in non-FCH patients versus 15% in FCH patients, p = 0.004). An early diagnosis of FCH may be suggested by the presence of marked disease activity when acute hepatitis is diagnosed and when a high viral load is present. The initiation of anti-HCV therapy should be considered at this point.

RESUMEN

Solid organ transplantations (SOT) are performed successfully in selected HIV-infected patients. However, multiple and reciprocal drug-drug interactions are observed between antiretroviral (ARV) drugs and calcineurin inhibitors (CNIs) through CYP450 metabolization. Raltegravir (RAL), a novel HIV-1 integrase inhibitor, is not a substrate of CYP450 enzymes. We retrospectively reviewed the outcomes of 13 HIV-infected transplant patients treated by an RAL + two nucleosidic reverse transcriptase inhibitor (NRTI) regimen, in terms of tolerability, ARV efficacy (plasma viral load, CD4 cell count), drug interactions, RAL pharmacokinetics and transplant outcome. Thirteen patients with liver (n = 8) or kidney (n = 5) transplantation were included. RAL was initiated (400 mg BID) either at time of transplantation (n = 6), or after transplantation (n = 7). Median RAL trough concentration was 507 ng/mL (176-890), which is above the in vitro IC95 for wild type HIV-1 strains (15 ng/mL). Target trough levels of CNIs were promptly obtained with standard dosages of tacrolimus or cyclosporine. RAL tolerability was excellent. There was no episode of acute rejection. HIV infection remained controlled. After a median follow-up of 9 months (range: 6-14), all patients were alive with satisfactory graft function. The use of an RAL + two NRTI-based regimen is a good alternative in HIV-infected patients undergoing SOT.

RESUMEN

The prognosis of HIV infection has been modified by antiretroviral therapy. However, the morbidity and the mortality of HCV co-infection increase and may be a major problem of health service. Up to now co-infected patients are excluded of transplantation due to complexity, the ethical aspects, the immunodeficiency and the co-infection. This study tries to estimate the feasibility in this population. Between December 1999 and March 2002, seven patients were transplanted. The average of CD4 was 332/ml; the viral load was <50 copies/ml. Before transplantation, no patient had experienced opportunist infection and all patients received antiretroviral therapy adapted to their history. The average follow-up is of 14 months: one patient died 3 months after transplantation, the other one presented a candida in oesophagus, the average of CD4 was 280/ml, and viral load was <50 copies/ml in five patients. A relapse of HVC was observed in all patients. Interferon/rivabirine therapy was proposed for four patients. Every patient received tacrolimus and corticoids. HAART were modified four times for toxicity and one time for virological failure. We observed two cases of transient renal insufficiency, two cases of diabetes, two cases of pancreatitis, and abnormalities of the respiratory mitochondrial chain in four patients. Finally, liver transplantation in HIV-HCV co-infected patients seems to be feasible when strict criteria of selection are taken into account. This still experimental strategy requires a multidisciplinary partnership.

RESUMEN

This article describes a case of enteritis in a 3.5-yr-old child with persistent diarrhea and the isolation of three gastrointestinal pathogens, including a rare human pathogen Hymenolepis diminuta (rat tapeworm). This is the first reported case in the northeastern United States in 20 yr and demonstrates that persons living in homes infested with rodents and arthropods are at risk of acquiring this infection.
