Amikacin Liposomal Inhalation Suspension in the Treatment of Mycobacterium abscessus Lung Infection: A French Observational Experience.

Background: Mycobacterium abscessus infections remain difficult to manage in both cystic fibrosis (CF) and non-CF patients and reported clinical outcomes are largely unsatisfactory. Clinical trial data are limited and no approved therapies are currently available for the management of M abscessus lung diseases. As an alternative, cohort studies may provide insightful information into the management of M abscessus pulmonary disease. Methods: Based on a retrospective observational cohort study, we investigated the safety and efficacy of amikacin liposome inhaled suspension (ALIS) as an adjunct to a standard antibiotic regimen for M abscessus lung infection in both CF and non-CF patients. We also assessed the association of patient drug compliance with culture conversion and clinical outcomes. Results: Twenty-six patients had long-term follow-up data available. Culture conversion was achieved in 54% (14/26) of the patients with no difference between CF and non-CF patients after an average treatment duration of 10 months. Patient treatment compliance was significantly better in the converter group compared to nonconverters with an odds ratio of 44.78 associated with good compared to poor patient compliance. Overall, 9 patients (35%) experienced an adverse event that led to treatment discontinuation. Conclusions: ALIS appears beneficial in both CF and non-CF populations with M abscessus lung disease.

Acute clinical hepatitis by immune restoration in a human immunodeficiency virus/hepatitis B virus co-infected patient receiving antiretroviral therapy.

We describe a human immunodeficiency virus (HIV)-infected patient with chronic active hepatitis B. The patient presented with acute clinical hepatitis during highly active antiretroviral therapy concomitant with immunovirological improvement of HIV infection. The hepatitis resolved within a few weeks despite the pursuit of antiretroviral drugs. Hepatitis B tests, which remained unchanged after two cycles of interferon alfa therapy and continuous administration of lamivudine, were improved with the clearance of hepatitis B virus (HBV) early antigen (HBeAg), the detection of antibody to HBV early antigen (HBeAb) and the undetectability of serum HBV DNA. Several months after this episode, HBV and HIV tests are still controlled.
