Myelosuppression observed in patients with inflammatory bowel disease (IBD) treated with azathioprine (AZA) has been attributed to low thiopurine S-methyltransferase (TPMT) activity. TPMT activity is dependent on the genetic polymorphism of high-versus low-metabolizing alleles. We investigated the association between TPMT genotypes and myelosuppression in Japanese IBD patients. ⋯ TPMT mutations are not associated with myelosuppression in Japanese IBD patients. Even in IBD patients with a wild TPMT genotype, clinicians should pay attention for the possible development of myelosuppression.

Comparative Study
Natural human interferon beta plus ribavirin combination therapy in Japanese patients infected with hepatitis C virus and a high viral load.
The aim of this pilot study was to determine the safety and efficacy of natural human interferon beta (nIFNbeta) plus ribavirin (RBV) in patients with chronic hepatitis C who did not respond to pegylated interferon alpha (PEG-IFN), with special emphasis on the incidence of mental disorders or refusal for fear of adverse effects. ⋯ nIFNbeta-RBV therapy offers sufficient safety and efficacy for patients with mental disorders, and thus could represent an excellent second-line therapy for subpopulations that are not suitable for PEG-IFN-RBV.

The goal of this study was to evaluate the safety and efficacy of mechanical ventilation (MV), including noninvasive positive pressure ventilation (NPPV) and endotracheal intubation (ETI) in patients with very severe hypoxemia due to refractory heart failure (RHF). ⋯ Both NPPV and ETI are safe and effective modalities for improving hypoxemia and left heart function in patients with RHF. These results suggest that invasive MV should be applied to very severe patients with RHF as quickly as possible when an expected clinical improvement cannot be obtained by NPPV.

The effect of clinical pathway (CP) care and early switch from intravenous to oral antibiotics therapy on community-acquired pneumonia (CAP) has been well documented. However, limited studies have evaluated the effects of CP on reducing time taken for attaining clinical stability and duration of antibiotics prescriptions. This study was aimed to investigate the use of a CP and its implication for CAP in a community hospital. ⋯ Implementation of this CP would lead to effective care, may serve to reduce time for attaining clinical stability and reduce the use of unnecessary antibiotics without worsening clinical outcomes in mild and moderate CAP.
