Boceprevir plus pegylated interferon/ribavirin to re-treat hepatitis C virus genotype 1 in HIV-HCV co-infected patients: final results of the Spanish BOC HIV-HCV Study.

INTRODUCTION: Boceprevir (BOC) was one of the first oral inhibitors of hepatitis C virus (HCV) NS3 protease to be developed. This study assessed the safety and efficacy of BOC+pegylated interferon-α2a/ribavirin (PEG-IFN/RBV) in the retreatment of HIV-HCV co-infected patients with HCV genotype 1. METHODS: This was a phase III prospective trial. HIV-HCV (genotype 1) co-infected patients from 16 hospitals in Spain were included. These patients received 4 weeks of PEG-IFN/RBV (lead-in), followed by response-guided therapy with PEG-IFN/RBV plus BOC (a fixed 44 weeks was indicated in the case of cirrhosis). The primary endpoint was the sustained virological response (SVR) rate at 24 weeks post-treatment. Efficacy and safety were evaluated in all patients who received at least one dose of the study drug. RESULTS: From June 2013 to April 2014, 102 patients were enrolled, 98 of whom received at least one treatment dose. Seventy-three percent were male, 34% were cirrhotic, 23% had IL28b CC, 65% had genotype 1a, and 41% were previous null responders. The overall SVR rate was 67%. Previous null-responders and cirrhotic patients had lower SVR rates (57% and 51%, respectively). Seventy-six patients (78%) completed the therapy scheme; the most common reasons for discontinuation were lack of response at week 12 (12 patients) and adverse events (six patients). CONCLUSIONS: Response-guided therapy with BOC in combination with PEG-IFN/RBV led to an overall SVR rate of 67%, but an SVR rate of only 51% in patients with cirrhosis. The therapy was generally well tolerated. Although the current standards of care do not include BOC+PEG-IFN/RBV, the authors believe that this combination can be beneficial in situations where new HCV direct antiviral agent interferon-free therapies are not available yet.

A cross-sectional epidemiological study of chronic HCV liver disease stage in HIV-coinfected patients using noninvasive techniques: CoTrans- GEENI Study.

BACKGROUND & AIMS: Considering the disadvantages of liver biopsy, alternative noninvasive methods have been sought to assess the stage of liver fibrosis. The aim of this study is to determine the prevalence of different stages of chronic liver disease using noninvasive methods (transition elastography (Fibroscan®) and Forns and AST-to-platelet ratio index-APRI-indexes) in HCV/HIV-coinfected patients. MATERIALS & METHODS: An observational, cross-sectional, multicenter study conducted between September 2007 and May 2008. The study enrolled coinfected patients who had a transient elastography performed in the year of the study and/or biochemical markers (Forns/APRI indexes) to assess the stage of liver fibrosis. RESULTS: A total of 109 patients were finally enrolled. Mean elastography velocity was 15.3 kPa, and mean APRI and Forns indexes were 1.4 and 6.1, respectively. According to transient elastography: 41% had mild, 24% moderate, and 35% severe fibrosis; 35% with significant fibrosis. According to the APRI index: 29% had mild, 45% moderate, and 26% severe fibrosis; 28% with significant fibrosis. According to the Forns index: 16% had mild, 54% moderate, and 30% severe fibrosis; 30% with significant fibrosis. The Kappa concordance index between the three methods was 0.42 for fibrosis stage and 0.52 for significant fibrosis detection (p < 0.001 in both cases). CONCLUSIONS: There is concordance between the APRI and Forns indexes and elastography in the detection of different fibrosis stages and it is significant. Transient elastography agrees with these indexes in the detection of significant and severe fibrosis.

[Cryptococcosis with exclusive cutaneous presentation in a patient with AIDS]. / Criptococosis de presentación exclusivamente cutánea en un paciente con SIDA.

We report an exclusively cutaneous case of cryptococcosis, which is exceptional. He was a 33 years old patient with the acquired immunodeficiency syndrome who presented with an ulcer-necrotic lesion at the nasal wings with a long and torpid evolution. Finally, culture and biopsy were diagnostic of cryptococcosis. We ruled out affection of other organs and the cryptococcal antigen was negative in serum and cerebrospinal fluid. The patient was treated with fluconazole and had a good clinical course. Its emphasized the scarcity of this form of presentation as well as the lack of specificity of its lesions and the necessity of ruling out other locations once the fungus is isolated in the skin. Diagnosis is simple through skin biopsy and culture. Its important to determine the cryptococcal antigen. We comment on the current approaches to treatment during acute and maintenance phases, after the appearance of the new imidazolic compounds such as fluconazole.
