ABSTRACT

BACKGROUND: Management of unfit AML patients is a therapeutic challenge. Most hematologists tend to avoid aggressive treatment leaving patients with a choice of best supportive care. We hypothesized that metronomic chemotherapy could be an alternative treatment for unfit AML patients. METHODS: A multi-center randomized controlled trial was conducted in seven university-affiliated hospitals in Thailand. Unfit AML patients were recruited and followed up from December 2014 to December 2017. Patients were randomly assigned to receive either metronomic chemotherapy or palliative hydroxyurea. Overall survival rates were compared using Cox's proportional hazard survival analysis. RESULTS: A total of 81 eligible patients were randomly allocated and included for ITT analysis. The OS rate was higher in group receiving metronomic chemotherapy than in group receiving palliative treatment at 6 and 12 months with borderline significance (6 months HR 0.60; 95%CI 0.36, 1.02; p-value 0.060; 12 months: HR 0.66; 95%CI 0.41, 1.08; p-value 0.097). CONCLUSION: Metronomic chemotherapy could prolong survival time of unfit AML patients, especially in the first 12 months after diagnosis without increasing treatment-associated adverse events.

ABSTRACT

In July 2009, a pandemic influenza (H1N1) (pdm H1N1) virus epidemic emerged rapidly in Phitsanulok, Thailand. Adult cases of community-acquired pneumonia (CAP) were prospectively examined for pdm H1N1 virus infections by real-time PCR in a tertiary hospital in Phitsanulok from July to November 2009. Twenty-four cases of pdm H1N1 virus-associated CAP were confirmed, and their clinical features including bacterial infection, severity of disease, course of admission, treatment, and outcome were investigated. The median age of these cases was 39.5 years. Most cases appeared to be primary viral pneumonia, but only one case was positive for a urinary pneumococcal antigen. The median time from the onset of illness to admission was 4 days. All 24 patients received oseltamivir after admission. Twelve (50.0%) were defined as having severe CAP and 9 (37.5%) were diagnosed with acute respiratory distress syndrome (ARDS). During the study period, pdm H1N1 virus infections frequently caused severe CAP among young adults because of the delayed initiation of antiviral therapy. Of the 9 ARDS patients, 3 died of ventilator-associated pneumonia caused by multidrug-resistant Acinetobacter baumannii. Implementation of infection control targeting this pathogen is required in tertiary hospitals in Thailand.
