Effectiveness and safety of daclatasvir/sofosbuvir with or without ribavirin in genotype 3 hepatitis C virus infected patients. Results in real clinical practice.

OBJECTIVE: Direct-acting antivirals have shown high efficacy in all hepatitis C virus (HCV) genotypes, but genotype 3 (G3) treatments continue to be a challenge, mainly in cirrhotic patients. The aim of this study is to analyse effectiveness and safety of daclatasvir associated with sofosbuvir with or without ribavirin in G3-HCV infected patients in real clinical practice. METHODS: An observational, prospective, cohort study over 2.5 years, in G3-HCV infected adult patients, in all fibrosis stages including patients with decompensated cirrhosis. Treatment was a combination of sofosbuvir 400 mg/day + daclatasvir 60 mg/day, with or without a weight-adjusted dosing of ribavirin for 12 or 24 weeks. The primary efficacy endpoint was sustained virologic response rates 12 weeks after therapy (SVR12). The primary safety endpoint was treatment withdrawal rates secondary to severe adverse events. RESULTS: A total of 111 patients were enrolled, 32.4% cirrhotics and 29.9% treatment-experienced. The global SVR12 rate was 94.6%, while the SVR12 rate in F3-4 fibrosis stage patients was 90.8% versus 100% in patients with F0-2 fibrosis (p=0.03). In cirrhotic patients, SVR12 was 100% versus 40% depending on whether ribavirin was added or not to daclatasvir/sofosbuvir (p=0.001). No other patient or treatment basal variables influenced the treatment effectiveness. No patient treatment withdrawal secondary to severe adverse events was observed. CONCLUSIONS: Daclatasvir/sofosbuvir ± ribavirin is highly effective in G3-HCV infected patients. Advanced degrees of fibrosis significantly decrease the effectiveness of this treatment, which motivates the need for the addition of ribavirin in cirrhotic patients. The regimen was safe and well tolerated.

[Epidermoid cyst: a rare cause of cystic liver disease]. / Quiste epidermoide: una causa infrecuente de patología quística hepática.

We present the case of a 42-year-old male patient with a large hepatic cyst, simulating a hydatid cyst. Subtotal cystectomy was performed. Thirteen months after this procedure the patient relapsed and a second laparotomy and total cystectomy were performed. A histopathological diagnosis of epidermoid cyst of the liver was made. The differential diagnosis of epidermoid cysts of the liver is broad and definitive diagnosis is usually only obtained after pathological examination of the surgical specimen. For this reason, and because of the potential for neoplasia, complete resection of the hepatic lesion should be attempted.

[Acute pancreatitis associated with varicella-zoster virus infection in a patient with acquired immunodeficiency syndrome]. / Pancreatitis aguda asociada a infección por virus de la varicela-zoster en un paciente con síndrome de inmunodeficiencia adquirida.

A patient with the acquired immunodeficiency syndrome (AIDS) who developed acute pancreatitis (AP) during the course of a disseminated herpes zoster is presented. Diagnosis was based on the simultaneity of abdominal pain with hyperamylasemia, the dissemination of the cutaneous lesions and the positive varicella-zoster virus serology at titres 1/640. Response to acyclovir treatment was spectacular. To our knowledge this is the second case of AP produced by the varicella-zoster virus and the first described in the course of disseminated herpes zoster. We believe that the varicella-zoster virus should be included within the causes of AP in patients with the human immunodeficiency virus.
