Real-life experience of hepatitis C treatment in a Spanish prison / Tratamiento de la hepatitis C en un centro penitenciario Español

Background. Hepatitis C virus (HCV) infection is a majorpublic health problem that causes multiple comorbidities. People in prisons who inject intravenous drugs are at increasedrisk of HCV infection, and HCV infection is 15-fold more prevalent among prisoners compared with the community. Theobjective of this study was to analyse the clinical and epidemiological characteristics of residents of a Spanish prison withHCV infection who received antiviral treatment.Material and methods. An observational, descriptiveand retrospective study was performed. All patients with HCVinfection diagnosed or followed up in an Infectious Diseasesattached to a penitentiary were included in this study.Results. Of 81 patients analysed, sixty-nine (83.1%) patients were male. The mean age was 50.1 (SD8.8) years, and 70%of the inmates had a history of injection drug use. Coinfectionwith HIV was detected in 30%. In up to 25% of the sample, therewere data on chronic liver disease in the degree of liver cirrhosis. The diagnosis of HCV infection had been made more than15 years earlier in 28% of those studied. Decompensations fromliver disease, hepatocellular carcinoma, or hospital admissionswere exceptional. Most of the inmates with HCV accepted treatment, and approximately 94% of the patients who completedtreatment achieved a sustained virological response without interactions or complications of interest.Conclusions. The availability of direct-acting antiviralsand their exceptional side effects constitute an opportunity toreduce the burden of HCV infection in Spain, particularly inthese high-risk populations.

Introducción. La infección por el virus de la hepatitis C(VHC) es un importante problema de salud pública con unagran morbimortalidad. El consumo de drogas inyectables es laprincipal vía de transmisión, siendo la infección por VHC 15veces más prevalente en las cárceles españolas respecto a lacomunidad. El objetivo de este estudio fue analizar las características clínico-epidemiológicas de los residentes de un centro penitenciario con VHC que recibieron tratamiento.Material y métodos. Estudio observacional, descriptivoy retrospectivo. Se incluyeron en este estudio todos los pacientes con infección por VHC diagnosticados o seguidos enuna Unidad de Enfermedades Infecciosas adscrito a un centropenitenciario.Resultados. De 81 pacientes analizados, sesenta y nueve(83,1%) pacientes eran varones. La edad media fue de 50,1 (DE8,8) años y el 70% de los internos tenía antecedentes de consumo de drogas inyectables. Se detectó coinfección por VIH en30%. En un 25% presentaban enfermedad hepática en gradode cirrosis. En el 28% de los internos el diagnóstico de VHC sehabía realizado hacia más de 15 años. Las descompensacionespor enfermedad hepática, carcinoma hepatocelular o ingresohospitalario fueron excepcionales. El 94% de los pacientes quecompletaron el tratamiento lograron una respuesta virológicasostenida sin interacciones ni complicaciones de interés.Conclusiones. La disponibilidad de antivirales de accióndirecta y sus excepcionales efectos secundarios constituyenuna oportunidad para reducir la carga de infección por VHCen España, especialmente en estas poblaciones de alto riesgo (AU)

Longterm Efficacy and Safety of Monotherapy versus Combination Therapy in Systemic Sclerosis-associated Pulmonary Arterial Hypertension: A Retrospective RESCLE Registry Study.

OBJECTIVE: Monotherapy is an option as first-line therapy for pulmonary arterial hypertension (PAH). However, combination therapy is a beneficial alternative. Our objective was to evaluate the efficacy of monotherapy versus combination therapy in patients with systemic sclerosis (SSc)-associated PAH. METHODS: All patients with SSc-associated PAH from the Spanish Scleroderma Registry (RESCLE) were reviewed. Patients were split into 3 groups: monotherapy versus sequential combination versus upfront combination therapy. The primary endpoint was death from any cause at 1, 3, and 5 years from PAH diagnosis. RESULTS: Seventy-six patients (4.2%) out of 1817 had SSc-related PAH. Thirty-four patients (45%) were receiving monotherapy [endothelin receptor antagonist (n = 22; 29%) or phosphodiesterase-5 inhibitors (n = 12; 16%)], 25 (33%) sequential combination, and 17 (22%) upfront combination therapy. A lower forced vital capacity/DLCO in the sequential combination group was reported (2.9 ± 1.1 vs 1.8 ± 0.4 vs 2.3 ± 0.8; p = 0.085) and also a higher mean pulmonary arterial pressure in combination groups (37.2 ± 8.7 mmHg vs 40.8 ± 8.8 vs 46 ± 15.9; p = 0.026) at baseline. Treatment regimen (p = 0.017) and functional class (p = 0.007) were found to be independent predictors of mortality. Sequential combination therapy was found to be an independent protective factor (HR 0.11, 95% CI 0.03-0.51; p = 0.004), while upfront combination therapy showed a trend (HR 0.68, 95% CI 0.23-1.97; p = 0.476). Survival from PAH diagnosis among monotherapy, sequential, and upfront combination groups was 78% versus 95.8% versus 94.1% at 1 year, 40.7% versus 81.5% versus 51.8% at 3 years, and 31.6% versus 56.5% versus 34.5% at 5 years (p = 0.007), respectively. Side effects were not significantly different among groups. CONCLUSION: Combination sequential therapy improved survival in our cohort.
