Interferon-Free Therapy in Elderly Patients With Advanced Liver Disease.

OBJECTIVES: Interferon-free therapies have an improved safety and efficacy profile. However, data in elderly patients, who have frequently advanced liver disease, associated comorbidities, and use concomitant medications are scarce. The im of this study was to assess the effectiveness and tolerability of all-oral regimens in elderly patients in real-life clinical practice. METHODS: Retrospective analysis of hepatitis C virus (HCV) patients aged ≥65 years receiving interferon-free regimens within the Spanish National Registry (Hepa-C). RESULTS: Data of 1,252 patients were recorded. Of these, 955 (76%) were aged 65-74 years, 211 (17%) were aged 75-79 years, and 86 (7%) were aged ≥80 years at the start of antiviral therapy. HCV genotype-1b was predominant (88%) and 48% were previous non-responders. A significant proportion of patients had cirrhosis (922; 74%), of whom 11% presented decompensated liver disease. The most used regimens were SOF/LDV (33%), 3D (28%), and SOF/SMV (26%). Ribavirin was added in 49% of patients. Overall, the sustained virological response (SVR12) rate was 94% without differences among the three age categories. Albumin ≤3.5 g/dl was the only independent negative predictor of response (0.25 (0.15-0.41); P<0.01). Regarding tolerability, the rate of severe adverse events increased with age category (8.8, 13, and 14%; P=0.04). In addition, the main predictors of mortality (2.3%) were age ≥75 years (2.59 (1.16-5.83); P =0.02) and albumin ≤3.5 (17 (6.3-47); P <0.01). CONCLUSIONS: SVR rates with interferon-free regimens in elderly patients are high and comparable to the general population. Baseline low albumin levels (≤3.5 g/dl) was the only predictor of treatment failure. Importantly, the rate of severe adverse events and death increased with age. Elderly patients (≥75 years) or those with advanced liver disease (albumin ≤3.5) presented higher mortality. Thus a careful selection of patients for antiviral treatment is recommended.

[Hepatitis B virus reactivation in rituximab-treated patients: incidence and risk factors]. / Reactivación del virus de la hepatitis B en pacientes tratados con rituximab: incidencia y factores de riesgo.

Hepatitis B virus (HBV) reactivation after chemotherapy regimens is a well-known complication. The incidence and risk factors for HBV reactivation remain to be elucidated. We aimed to determine the incidence and risk factors for HBV reactivation in patients receiving rituximab, and the potential role of the cumulative rituximab dose in HBV reactivation. We retrospectively reviewed 320 patients receiving rituximab in our hospital. Of these, 42 (13.12%) had serological markers of hepatitis B. During follow-up, 21% (9/42) had HBV reactivation. Risk factors for reactivation were HBsAg positivity (p < 0.05), isolated anti-HBc positivity (p < 0.05), marginal zone lymphoma, and Mantle cell lymphoma (p < 0.05). The median rituximab dose tended to be higher in patients with reactivation (p = 0.06).

Reactivación del virus de la hepatitis B en pacientes tratados con rituximab: incidencia y factores de riesgo / Hepatitis B virus reactivation in rituximab-treated patients: incidence and risk factors

La reactivación del virus de la hepatitis B en pacientes tratados con quimioterapia es una complicación conocida. La incidencia y los factores de riesgo aún no están bien definidos. El objetivo de nuestro estudio es determinar la incidencia y los factores de riesgo de la reactivación del virus de la hepatitis B en pacientes tratados con rituximab (RTX), e investigar si la dosis acumulada de RTX es un factor de riesgo independiente para la reactivación del virus de la hepatitis B. Se revisaron de forma retrospectiva 320 pacientes tratados con RTX en nuestro hospital, de los cuales 42 (13,12%) tenían marcadores serológicos de hepatitis B. Durante el seguimiento, 9 (21%) de los 42 pacientes con marcadores serológicos del virus de la hepatitis B presentaron una reactivación. Los factores de riesgo para la reactivación del virus de la hepatitis B fueron la presencia de HBsAg positivo (p < 0,05), anti-HBc aislado (p < 0,05), el linfoma de la zona marginal y linfoma de células del manto (p < 0,05) y la mediana de la dosis de rituximab tendió a ser mayor en los pacientes que presentaron reactivación (p = 0,06)
