Liver Stiffness Decreases Rapidly in Response to Successful Hepatitis C Treatment and Then Plateaus.

BACKGROUND AND AIM: To investigate the impact of a sustained virological response (SVR) to hepatitis C virus (HCV) treatment on liver stiffness (LS). METHODS: LS, measured by transient elastography (FibroScan), demographic and laboratory data of patients treated with interferon (IFN)-containing or IFN-free regimens who had an SVR24 (undetectable HCV viral load 24 weeks after the end of treatment) were analyzed using two-tailed paired t-tests, Mann-Whitney Wilcoxon Signed-rank tests and linear regression. Two time intervals were investigated: pre-treatment to SVR24 and SVR24 to the end of follow-up. LS scores ≥ 12.5 kPa indicated LS-defined cirrhosis. A p-value below 0.05 was considered statistically significant. RESULTS: The median age of the patients (n = 100) was 60 years [IQR (interquartile range) 54-64); 72% were male; 60% were Caucasian; and 42% had cirrhosis pre-treatment according to the FibroScan measurement. The median LS score dropped from 10.40 kPa (IQR: 7.25-18.60) pre-treatment to 7.60 kPa (IQR: 5.60-12.38) at SVR24, p <0.01. Among the 42 patients with LS-defined cirrhosis pre-treatment, 25 (60%) of patients still had LS scores ≥ 12.5 kPa at SVR24, indicating the persistence of cirrhosis. The median change in LS was similar in patients receiving IFN-containing and IFN-free regimens: -1.95 kPa (IQR: -5.75 --0.38) versus -2.40 kPa (IQR: -7.70 --0.23), p = 0.74. Among 56 patients with a post-SVR24 LS measurement, the LS score changed by an additional -0.90 kPa (IQR: -2.98-0.5) during a median follow-up time of 1.17 (IQR: 0.88-1.63) years, which was not a statistically significant decrease (p = 0.99). CONCLUSIONS: LS decreased from pre-treatment to SVR24, but did not decrease significantly during additional follow-up. Earlier treatment may be needed to reduce the burden of liver disease.

Intrabronchial valves for treatment of alveolar-pleural fistula in a patient with Pneumocystis jirovecii pneumonia.

Alveolo-pleural fistula is a common complication of severe pulmonary infection. Some patients require long-term placement of chest tubes until spontaneous closure of the fistula takes place, whereas others require surgical intervention. We report a case of a patient with alveolo-pleural fistula secondary to Pneumocystis jirovecii pneumonia who was successfully treated with the use of intrabronchial unidirectional valves inserted using flexible bronchoscopy.

Hepatitis C Virus Treatment in HIV-Coinfected Patients: No Longer Different From Monoinfection Treatment.

Between 15% and 30% of patients infected with HIV in the United States and Europe are coinfected with hepatitis C virus (HCV), and rates of acute HCV infection have been increasing in some populations of HIV-positive patients. Liver disease is now a leading cause of death in HIV-infected patients. Patients with HIV/HCV coinfection have lower rates of spontaneous acute HCV clearance, poorer response to treatment of chronic HCV in the pre-direct-acting antiviral era, more rapid progression to cirrhosis, and increased risk of hepatocellular carcinoma. This article will summarize data on management of HIV/HCV coinfection, discuss the epidemic of acute HCV infection in HIV-infected patients, and examine the many new HCV treatment regimens on the horizon with data on coinfected patients.
