Abstract
10 consecutive years of observation of the laboratory data of quantitative urinary bacterial culture in the Central Clinical Laboratory of Osaka University Hospital was made. The marked rise of Pseudomonas and other Enterobacteriaceae was clearly demonstrated. The difference in bacterial species in bacteriuria between inpatients and outpatients strongly suggests that the origin of infection was quite different. The disappearance of Staph. aureus as a causative agent was also demonstrated.

Abstract
OBJECTIVES A number of reports have shown that the efficacy of mycophenolate mofetil (MMF) is superior to that of azathioprine (AZP) for long-term kidney allograft survival. We conducted a retrospective single-center study to evaluate renal function more than 2 years after conversion from AZP to MMF in kidney transplant recipients several years after transplantation. METHODS AZP was converted to MMF in 51 recipients at 17.0 ± 0.8 years after kidney transplantation who were followed up for more than 2 years after conversion. Estimated glomerular filtration rate (eGFR) was determined using the Formula of the Japanese Society of Nephrology. RESULTS The eGFR was significantly greater at 1 year before conversion (41.72 ± 1.91 mL/min/1.73 m(2)) as compared with the day of conversion (39.04 ± 1.82 mL/min/1.73 m(2); P < .05). After conversion, eGFR plateaued to 39.30 ± 2.01 mL/min/1.73 m(2) at 1 year and 38.24 ± 2.42 mL/min/1.73 m(2) at 2 years after conversion. The average eGFR slopes were -2.96 ± 0.36 mL/min/1.73 m(2) per year for AZP and 1.22 ± 0.10 mL/min/1.73 m(2) per year for MMF (P < .0001). Cyclosporine (CSA) was reduced from 176 ± 9.3 to 165 ± 9.8 mg/d (P = .0394) after the switch, whereas the CSA trough level was increased from 77.3 ± 6.6 to 118 ± 9.8 ng/mL (P = .0017). Furthermore, the daily dose of tacrolimus (TAC) was decreased from 3.5 ± 0.3 to 3.1 ± 0.3 mg/d (P = .0083). CONCLUSIONS Our findings demonstrated the safety of conversion from AZP to MMF even in the patients who underwent renal transplantation several years prior. In addition, these short-term results indicated the improvement in allograft function following conversion.

Abstract
AIMS To evaluate the efficacy and safety of the selective sodium glucose co-transporter 2 inhibitor dapagliflozin in Japanese patients with type 2 diabetes mellitus (T2DM) inadequately controlled by diet and exercise. METHODS Patients received placebo or dapagliflozin (5 or 10 mg) once daily for 24 weeks. The primary outcome measure was change from baseline in glycated haemoglobin (HbA1c). RESULTS Patients (N = 261) had modestly elevated baseline HbA1c (mean ≈ 7.5%) and most had mild or moderate renal impairment (estimated glomerular filtration rate range 43-103 ml/min/1.73 m(2)). Greater reductions in mean HbA1c level were observed with dapagliflozin (5 mg, -0.41%; 10 mg, -0.45%) than with placebo (-0.06%) at week 24 and these were greater in patients with higher baseline HbA1c levels. Fasting plasma glucose (FPG) was also significantly reduced with dapagliflozin (5 mg, -8.6 mg/dl; 10 mg, -13.7 mg/dl) compared with placebo (+5.8 mg/dl). Dapagliflozin significantly reduced body weight (5 mg, -2.13 kg; 10 mg, -2.22 kg) compared with placebo (-0.84 kg). Overall, 47.7 and 64.8% of patients with dapagliflozin 5 and 10 mg, respectively, and 51.7% with placebo experienced ≥ 1 adverse event, mostly mild or moderate, and unrelated to study treatment. Two patients on dapagliflozin 10 mg reported hypoglycaemia. Four patients across all groups reported events suggestive of genital infection and four of urinary tract infection. No events of pyelonephritis were reported. CONCLUSION Dapagliflozin (5 and 10 mg) was well tolerated and effective in reducing HbA1c, FPG and body weight over 24 weeks in Japanese patients with T2DM inadequately controlled by diet and exercise.

Abstract
OBJECTIVES To assess the effect of the major efavirenz metabolizing enzyme (CYP2B6) genotype and the effects of rifampicin co-treatment on induction of CYP3A by efavirenz. PATIENTS AND METHODS Two study arms (arm 1, n = 41 and arm 2, n = 21) were recruited into this study. In arm 1, cholesterol and 4β-hydroxycholesterol were measured in HIV treatment-naive patients at baseline and then at 4 and 16 weeks after initiation of efavirenz-based antiretroviral therapy. In arm 2, cholesterol and 4β-hydroxycholesterol were measured among patients taking efavirenz during rifampicin-based tuberculosis (TB) treatment (efavirenz/rifampicin) just before completion of TB treatment and then serially following completion of TB treatment (efavirenz alone). Non-linear mixed-effect modelling was performed. RESULTS A one-compartment, enzyme turnover model described 4β-hydroxycholesterol kinetics adequately. Efavirenz treatment in arm 1 resulted in 1.74 (relative standard error = 15%), 3.3 (relative standard error = 33.1%) and 4.0 (relative standard error = 37.1%) average fold induction of CYP3A for extensive (CYP2B6*1/*1), intermediate (CYP2B6*1/*6) and slow (CYP2B6*6/*6) efavirenz metabolizers, respectively. The rate constant of 4β-hydroxycholesterol formation [mean (95% CI)] just before completion of TB treatment [efavirenz/rifampicin co-treatment, 7.40 × 10(-7) h(-1) (5.5 × 10(-7)-1.0 × 10(-6))] was significantly higher than that calculated 8 weeks after completion [efavirenz alone, 4.50 × 10(-7) h(-1) (4.40 × 10(-7)-4.52 × 10(-7))]. The CYP3A induction dropped to 62% of its maximum by week 8 of completion. CONCLUSIONS Our results indicate that efavirenz induction of CYP3A is influenced by CYP2B6 genetic polymorphisms and that efavirenz/rifampicin co-treatment results in higher induction than efavirenz alone.

Abstract
BACKGROUND The role of microchimerism found in the peripheral blood of renal transplant recipients remains a matter of debate. We assessed the frequency of microchimerism after kidney transplantation and examined its influence on clinical courses over a 12-month follow-up period. PATIENTS AND METHODS Ten single-kidney recipients underwent microchimerism detection at 2 days, 2 weeks, and 1, 3, 6, and 12 months after transplantation, with mismatch human leukocyte antigen (HLA)-A, -B, and -C used as markers. RESULTS Microchimerism was detected in 8 (80%) patients at 2 days after kidney transplantation. In 3 of those, microchimerism became negative within 3 months after transplantation, whereas it remained present for up to 12 months in 3 patients (33 %). There was 1 acute rejection episode in a patient in whom microchimerism became negative within 3 months. Protocol renal graft biopsy specimens obtained 3 months after transplantation revealed no acute cellular-mediated rejection (ACMR) or acute antibody-mediated rejection (AAMR) in the 5 patients positive for microchimerism at 3 months. CONCLUSIONS Microchimerism was frequently detected after kidney transplantation. Microchimerism that remained for more than 3 months post-transplantation might be correlated with a lower incidence of rejection, thus its monitoring may help identify recipients with a low rejection risk.
