Abstract
OBJECTIVES We investigated the efficacy and safety of tacrolimus (TAC) by monitoring its serum concentration for mothers and infants in pregnant patients with systemic lupus erythematosus (SLE). METHODS We measured trough concentrations of TAC in 25 pregnant patients with SLE to assess influence of TAC on the disease activity. Additionally, we measured the concentrations of TAC in umbilical arterial blood, breast milk, and breastfed infants to investigate the safety of TAC for the mothers and infants. RESULTS The trough concentrations of TAC in the mothers significantly decreased in the second trimester as compared with those before pregnancy. However, the decrease in the trough concentrations of TAC did not lead to the deterioration of SLE. When examined, the doses of TAC were significantly lower in the second trimester and postpartum in the deteriorating group than those in the non-deteriorating group. There were no adverse events by TAC in mothers and fetuses. The concentrations of TAC in the umbilical cord blood were lower than those in the maternal blood. The relative infant dose in breastfed infants of TAC was < 1%. The level of TAC in infant bloods was below detectable limits. CONCLUSION These findings suggest that TAC is one of the most effective and safest immunosuppressive drugs for use in pregnant patients with SLE.

Abstract
Serum squamous cell carcinoma related antigen (SCC-Ag) values were determined in 86 patients with urothelial cancers. Mean + standard deviation for serum SCC-Ag. was 3.4 ± 0.98 ng/ml and positive values (> 2.0 ng/ml) were found in 27%. Neither pathological stage nor cell grade of the urothelial cancer showed any relation to serum SCC-Ag. Serum SCC-Ag. changed parallel to the clinical course. These results suggest that, as there is no specific tumor marker in urothelial cancer, serum SCC-Ag. may be a useful aid in diagnosing cancer and monitoring these patients. Used together with another non-specific marker, an increase in the accuracy of diagnosis of these malignancies can be expected.

Abstract
Azathioprine (AZA) is increasingly being prescribed to rheumatoid arthritis (RA) patients. Following oral administration, AZA is converted into its active form. Inflammatory bowel disease (IBD) and systemic lupus erythematosus (SLE) patients with low thiopurine (S)-methyltransferase (TPMT) activity tend to respond well to AZA therapy. In a previous study of Japanese SLE patients under low-dose AZA therapy, the group with the 94C>A mutation in inosine triphosphatase (ITPA) showed greater improvement in their disease activity index. However, it is not yet clear how genotypes relate to responsiveness to RA treatment. The genotypes ITPA 94C>A, TPMT*3C, NUDT15 595C>T, GST-M1, GST-T1 and MRP4/ABCC4 2269G>A of Japanese patients with RA were determined. The relationship between these genotypes and response to AZA therapy was evaluated using the Disease Activity Score 28 (DAS28) and various medical data. Of the 22 patients 15 had the ITPA 94C/C genotype, 7 had the ITPA 94C/A genotype, none had the TPMT*3C mutation, 4 had the NUDT15 595C>T mutation, 8 had the GST-M1 and T1 null genotypes and 9 had the MRP4/ABCC4 2269G>A mutation. Changes in DAS28 at 6 months after baseline were similar in both ITPA genotype groups. However, the maintenance dose of AZA was significantly lower in the C/A group than in the C/C group (0.85±0.30 mg/kg/day vs. 1.2±0.46 mg/kg/day, respectively; p = 0.043). The ITPA 94C/A group showed the same response to RA treatment as the C/C group, but at a lower dose. This demonstrates that RA patients with the ITPA 94C>A mutation are more responsive to AZA.

Abstract
Summary10 healthy female subjects and 15 female patients with essential hypertension were studied with respect to fibrinogen metabolism in a steady state. Autologous I-125-labeled fibrinogen (I-125-fibrinogen) was used as a tracer. Comparison of the results showed that plasma volume, t½ of plasma I-125-fibrinogen and fractional catabolic rate (j3p) of plasma fibrinogen were not appreciably different in both groups of subjects, but plasma fibrinogen concentration, and catabolic flux of (synthesis rate) were significantly higher in hypertensive subjects, whereas extravascular fibrinogen and fractional transcapillary transfer rate (j1) of were significantly decreased in the patients. Further analyses of the data in both groups showed that there were significant correlations between diastolic blood pressure (P) and j1 with a regression equation of j1 = e−0.0285P, between 1 and between and j1 with a regression equation of 1. These results indicate that the observed decrease of j1 triggered the transition from normal to pathological steady state and is responsible for the altered metabolism and distribution of fibrinogen in hypertensive subjects.

Abstract
BACKGROUND Functional dyspepsia (FD), a heterogeneous disorder, involves multiple pathogenetic mechanisms. Developing treatments for FD has been challenging. We performed a randomized, placebo-controlled, double-blind clinical trial to determine the efficacy of rikkunshito, a Japanese herbal medicine, in FD patients. METHODS FD patients (n = 192) who met the Rome III criteria without Helicobacter pylori infection, predominant heartburn, and depression were enrolled at 56 hospitals in Japan. After 2 weeks of single-blind placebo treatment, 128 patients with continuous symptoms were randomly assigned to 8 weeks of rikkunshito (n = 64) or placebo (n = 61). The primary efficacy endpoint was global assessment of overall treatment efficacy (OTE). The secondary efficacy endpoints were improvements in upper gastrointestinal symptoms evaluated by the Patient Assessment of Upper Gastrointestinal Disorders-Symptom Severity Index (PAGI-SYM), the Global Overall Symptom scale (GOS), and the modified Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (m-FSSG), and psychological symptoms evaluated by the Hospital Anxiety and Depression Scale (HADS). KEY RESULTS Rikkunshito increased OTE compared to placebo at 8 weeks (P = .019). Rikkunshito improved upper gastrointestinal symptoms (PAGI-SYM, GOS, and m-FSSG) at 8 weeks, especially postprandial fullness/early satiety (P = .015 and P = .001) and bloating (P = .007 and P = .002) of the PAGI-SYM subscales at 4 weeks and 8 weeks. Improvement of HADS at 8 weeks (P = .027) correlated with those of PAGI-SYM (r = .302, P = .001), GOS (r = .186, P = .044), and m-FSSG (r = .462, P < .001), postprandial fullness/early satiety (r = .226, P = .014), dyspepsia (r = .215, P = .019), and PDS (r = .221, P = .016). CONCLUSION & INFERENCES Rikkunshito may be beneficial for FD patients to simultaneously treat gastrointestinal and psychological symptoms.

Abstract
Objective The objective of this study is to investigate the effectiveness of discontinuation of risedronate for patients with systemic lupus erythematosus (SLE) treated with glucocorticoid (GC). Methods The participants were patients with SLE treated with prednisolone (PSL) ≥ 2 mg/day and risedronate for at least three years. Lumbar spine and total hip bone mineral density (BMD) measurements were taken at baseline and 24 and 48 weeks after discontinuation of risedronate, and bone turnover markers were evaluated at baseline, 12, 24, 36, and 48 weeks. Results A total of 36 patients were enrolled, 25 of whom discontinued risedronate. The mean age was 46.8 ± 11.2 years, and 23 were female. The mean duration of GC treatment was 14.8 ± 11.4 years, the mean dose of PSL was 7.8 ± 3.9 mg/day, and the mean duration of risedronate was 5.8 ± 2.4 years. Seventeen patients showed decreased lumbar spine BMD at 48 weeks after discontinuation of risedronate, with a mean lumbar spine lumbar decrease of 1.42% ± 3.20% ( p = 0.034); 17 patients (71%) showed a decreased total hip BMD at 48 weeks after discontinuation of risedronate, with a mean total hip BMD decrease of 0.99% ± 2.10% ( p = 0.021). Serum tartrate-resistant acid phosphatase 5b (TRACP-5b) ≥ 309 mU/dl at baseline was a risk factor for decreased total hip BMD at 48 weeks compared with serum TRACP-5b < 309 mU/dl (56% vs 0%, p = 0.0098). One patient developed a clinical fracture of the lumbar spine at 20 weeks. Conclusions Discontinuation of risedronate treatment in patients with SLE who had received GC therapy led to decreases in lumbar spine and total hip BMD, particularly in patients with high baseline serum TRACP-5b levels.

Abstract
The choroid affected by the Vogt-Koyanagi-Harada syndrome (VKH) has seldom been explored by indocyanine green choroidal angiography. Five patients with definite diagnosis of VKH underwent this investigation. The first case had the most marked leakage, very similar to that on fluorescein angiography. The right eye of case 2 showed fewer leakage points on ICG than on fluorescein angiography, compared with case 1. The left eye of case 2 did not show any leakage. Cases 3, 4 and 5 yielded segmental hyperfluorescence, distant from the posterior pole, which could not be identified by fluorescein angiography. This might indicate segmental choroiditis. There were two types of hypofluorescent lesions; all the cases except case 2 showed early hypofluorescence. Hypofluorescent areas corresponding to overlying retinal detachment were seen in the right eye of case 4. Multiple spots, late hypofluorescence, about 200 to 500 um in size appeared throughout the posterior pole in four eyes out of ten. In conclusion, indocyanine green choroidal angiography provides a wider variety of pictures than fluorescein angiography.

Abstract
Everyday memories are encoded in the hippocampus and decay very rapidly. In contrast, everyday memory with novel experience before or after remains for a long time. Our research group applied optogenetics to behavioural test in mice. We revealed the possibility that non-canonical release of dopamine from the locus coeruleus into the hippocampus change trivial everyday memory to long-term memory.
