Abstract
INTRODUCTION Transient neonatal diabetes mellitus (TNDM) is a rare condition that is characterized by the presence of diabetes mellitus during the first 6 months of life and remission by 18 months of age. It usually relapses at a median age of 14 years. Hyperinsulinaemic hypoglycaemia is a relatively common complication during remission. Although β-cell function is reported to be impaired at relapse, the clinical course of glycaemic profiles during remission in patients with TNDM remains largely unknown. CASE PRESENTATION Longitudinal glycaemic profiles were investigated annually from remission (185 days) to relapse (14.5 years) in a patient with TNDM due to paternal 6q24 duplication using the oral glucose tolerance test (glucose intake: 1.75 g/kg to a maximum of 75 g). The patient's β-cell function and insulin sensitivity were assessed by calculating the insulinogenic index, homeostasis model assessment of β-cell function (HOMA-β), homeostasis model assessment of insulin resistance (HOMA-IR), quantitative insulin sensitivity check index, and Matsuda index. Early insulin response to glucose intake was impaired throughout remission, whereas fasting insulin and β-cell function by HOMA-β gradually increased in the first few years since remission, followed by a gradual decline in function. In contrast, HOMA-IR fluctuated and peaked at 6.5 years of age. CONCLUSION This is the first report of annual longitudinal glycaemic profiles in a patient with 6q24-related TNDM during remission. We identified fluctuations in β-cell function and insulin resistance during remission.

Abstract
Abstract
Background
Local impedance (LI) at a distal tip of the ablation catheter can indirectly measure catheter contact and tissue temperature during radiofrequency catheter ablation (RFCA). LI decreases by RFCA, and a degree of LI drop is correlated with lesion size. However, data on the effects of catheter contact angle on lesion size and LI drop were scarce. This study aimed to evaluate the influence of catheter contact angle on lesion size and LI drop in a porcine experimental study.
Methods
Lesions were created on porcine myocardial left ventricles by the LI-sensing ablation catheter (IntellaNav MiFi OI®). Contact force (CF) was measured using pressure to current transducer (load cell). Radiofrequency ablation was performed with a power of 30 Watt and a duration of 30 seconds. CF (0g, 5g, 10g, 20g, and 30g) and catheter angle (30°, 45°, and 90°) were changed in each set (total 120 lesions, n=8 each). LI rise, LI drop by RF application, and lesion size (maximum lesion width, maximum surface width, and maximum lesion depth) were evaluated.
Results
There was no angular dependence in LI rise in all CF. The values of LI rise increased as CF increased. The LI drop also increased as CF increased in all contact angles. Regarding the difference of catheter angles, LI drop with 90° was lower than those with 30° and 45°in CF 10g, 20g, and 30g, respectively. Maximum lesion width and surface width were larger in 30° and 45° than those in 90°, whereas there were no differences in maximum lesion depth.
Conclusion
LI drop in 90° were significantly lower than those in 45° and 30°. Although lesion depths were not different among the three angles, the absolute values of LI drop were different. Caution should be exercised to comprehend the LI drop with catheter angles.

Abstract
The essential trace element zinc maintains liver functions. Liver diseases can alter overall zinc concentrations, and hypozincemia is associated with various hepatic pathologies. Modulating systemic zinc through dietary supplementation is potentially useful for liver diseases. We evaluated the usefulness of zinc (NPC-02; acetate formulation) supplementation. We conducted two NPC-02 studies on zinc-deficient patients (serum zinc < 70 μg/dL). Study 1: double-blind, randomized, placebo-controlled trial on 57 subjects with chronic liver diseases comparing serum zinc in patients given NPC-02 (NPC-02 group) versus placebo (Placebo group). Study 2: dose adjustment study on 43 subjects with/without liver diseases to determine proportions maintaining serum zinc target (≥ 80 μg/dL but < 200 μg/dL). In study 1, NPC-02 subjects had higher serum zinc concentrations at week 8 than Placebo subjects (83.2 ± 20.2 and 61.3 ± 12.0, respectively; P < 0.0001), and more NPC-02 than Placebo subjects achieved the serum zinc target (15/27 vs. 1/26). In study 2, the NPC-02-induced serum zinc increase was dose-dependent in subjects both with and without liver diseases (r = 0.5143, P = 0.0022 and r = 0.5753, P = 0.0005, respectively). Interestingly, there was a marginally positive correlation between serum zinc and albumin levels in subjects with but not in those without liver diseases (r = 0.4028, P = 0.0631 and r = 0.1360, P = 0.5567, respectively). NPC-02 dose-dependently increases serum zinc in hypozincemic patients, regardless of liver disease. NPC-02 is a potentially effective therapy for liver cirrhosis, in which zinc deficiency is common. Clinical trial registry number: NCT02337569, NCT02321865.

Abstract
Unbalanced translocations of Y-chromosomal fragments harboring the sex-determining region Y gene (SRY) to the X chromosome or an autosome result in 46,XX and 45,X testicular disorders of sex development (DSD), respectively. Of these, Y;autosome translocation is an extremely rare condition. Here, we identified a 20-year-old man with a 45,X,t(Y;7)(q11.21;q35) karyotype, who exhibited unilateral cryptorchidism, small testis, intellectual disability, and various congenital anomalies. The fusion junction of the translocation was blunt, and the breakpoint-flanking regions shared only 50% similarity. These results indicate that Y;autosome translocations can occur between 2 low-similarity sequences, probably via nonhomologous end joining. Furthermore, translocations of a Ypterq11.21 fragment to 7q35 likely result in normal or only mildly impaired male-type sexual development, along with various clinical features of 7q deletion syndrome, although their effects on adult testicular function remain to be studied.

Abstract
Summary Objective. Assessing efficacy of mepolizumab on the upper and lower airways in severe eosinophilic asthma patients. Patients and methods. This study was a 48-week prospective open-label analysis of mepolizumab in 11 asthmatics with chronic rhinosinusitis (CRS). It was administered every 4 weeks. Six patients were aspirin-exacerbated respiratory disease (AERD). Results. Blood eosinophil count was reduced after the first administration, and was continued until 48 weeks. The Sino-Nasal Outcome Test scores, the Lund-MacKay CT scoring, and forced expiratory volume in 1 second were improved. Symptom scores of anosmia and nasal congestion were not improved in the patients with AERD. All oral corticosteroid-dependent patients successfully withdrew from corticosteroids. Conclusions. This pilot study showed mepolizumab improved nasal symptoms and lung function in severe eosinophilic asthma patients with CRS, suggesting efficacy of mepolizumab on the upper and lower airway symptoms in eosinophilic asthma.

Abstract
BACKGROUND Direct-acting antiviral (DAA) regimens have shown high efficacy and tolerability for patients with HCV genotype 1/1b (GT1/1b) in clinical trials. However, robust real-world evidence of interferon (IFN)-free DAA treatment for HCV GT1-infected patients in Asia is still lacking. AIM To systematically review and meta-analyse the effectiveness and tolerability of IFN-free DAA therapy for HCV GT1 infection in Asia. METHODS We included studies that enrolled adult patients with HCV GT1 infection in routine clinical practice in Asia, using IFN-free DAA regimens, and reported sustained virological response (SVR) after 12/24 weeks end-of-treatment by 31 May 2017. The pooled SVR rates were computed with a random-effects model. Subgroup analysis and meta-regression as previously registered in PROSPERO were performed to determine how pre-planned variables might have affected the pooled estimates. RESULTS We included 41 studies from eight countries and regions, comprising of 8574 individuals. The pooled SVR rates for GT1 were 89.9% (95% CI 88.6-91.1, I2 = 55.1%) with daclatasvir/asunaprevir (DCV/ASV) and 98.1% (95% CI 97.0-99.0, I2 = 41.0%) with ledipasvir/sofosbuvir ± ribavirin (LDV/SOF ± RBV). Baseline cirrhosis but not prior treatment history and age, attenuated the effectiveness of both regimens. Baseline resistance associated substitutions (RASs) severely attenuated SVR of DCV/ASV (65.4% vs 94.3%, P < 0.001) and only minimally with LDV/SOF ± RBV (94.5% vs 99.2%, P = 0.003). Patients with renal dysfunction treated with DCV/ASV showed a higher SVR rate (93.9% vs 89.8%, P = 0.046). Patients with hepatocellular carcinoma (HCC) LDV/SOF ± RBV achieved a lower SVR than those without HCC (94.1% vs 98.7%, P = 0.001). CONCLUSION All oral DAA treatment of HCV GT1 resulted in high cure rates in Asian patients in routine clinical practice setting including elderly patients and those with end-stage renal disease.

Abstract
We describe the case of a girl diagnosed with Graves’ disease (GD) at 2 yr of age, who
developed early puberty. Preoperative examination for craniosynostosis revealed
thyrotoxicosis. While she was tall and her bone age was advanced at GD onset, her linear
growth attenuated after commencement of anti-thyroid treatment. However, at approximately
6 yr of age, breast budding was recognized. Hormonal analysis revealed pubertal levels of
LH response to a GnRH stimulation test and serum E2. Gonadal suppression therapy with GnRH
agonist was initiated, and her adult stature slightly exceeded the genetic potential.
Although accelerated growth and skeletal maturation are often reported to occur at GD
onset in prepubertal patients, early puberty is unusual, and this is the first reported
case of sexual precocity in a girl with GD.

Abstract
BACKGROUND With the development of direct-acting anti-virals (DAAs), almost all patients with chronic hepatitis C virus (HCV) infection can achieve sustained viral response (SVR). AIM To evaluate the short-term risk of HCC among patients with SVR by DAAs, including those with cirrhosis or previous HCC. METHODS This large-scale, multicentre cohort study included 1,675 consecutive patients who achieved SVR by treatment with interferon-free sofosbuvir-based regimens, divided into groups with (n = 152) or without previous HCC (n = 1,523). The Kaplan-Meier method and Cox proportional hazard analysis were used to calculate the cumulative HCC incidence and related factors of HCC. RESULTS During the follow-up period (median: 17 months), 46 (2.7%) patients developed HCC. The 1-year cumulative rates of de novo HCC were 0.4% and 4.9% for the noncirrhosis and cirrhosis groups respectively (log-rank test: P < 0.001). For cirrhotic patients, serum α-fetoprotein level at the end of treatment (EOT-AFP) was the strongest predictor of de novo HCC. The 1-year cumulative de novo HCC rates were 1.4% and 13.1% in the EOT-AFP < 9.0 ng/mL and ≥ 9.0 ng/mL groups (cut-off value) respectively (log-rank test: P < 0.001). The 1-year cumulative rates of HCC recurrence were 6.5% and 23.1% for the noncirrhosis and cirrhosis groups respectively (log-rank test: P = 0.023). For cirrhotic patients, previous HCC characteristics were significantly associated with HCC recurrence. In contrast, sex, age and metabolic features did not influence de novo HCC or recurrence. CONCLUSIONS For cirrhotic patients after elimination of HCV, serum EOT-AFP level and previous HCC characteristics would be useful markers for predicting de novo HCC or recurrence.

Abstract
BACKGROUND Biotin deficiency has been reported in Japanese infants fed special formulas for medical reasons, including those with milk allergy and congenital metabolic diseases, because these formulas contain little biotin. Serum biotin measurement is useful for diagnosing biotin deficiency. We applied a simple and rapid method to analyze serum biotin, and established normal ranges for children and adults. METHODS Serum biotin in 188 healthy Japanese children aged 0-4 years and in 25 healthy adults was analyzed using a Biotin ELISA Kit (immundiagnostik). The effects of various conditions on the measurement of serum biotin were also examined. RESULTS Median biotin in children aged 0-4 years was 10.4 ng/dL (IQR, 7.9-13.4 ng/dL), and that in adults was 12.9 ng/dL (IQR, 10.8-15.8 ng/dL). Normal range was 4.7-22.0 ng/dL in children and 8.4-20.5 ng/dL in adults (calculated using two-sided 95%CI). Measurements obtained with this method were not affected by frozen storage, freeze-thaw, or hemolysis, indicating that serum biotin can be analyzed accurately under these conditions, with a possible application to plasma samples. CONCLUSIONS Serum biotin was significantly lower in children than in adults, with the normal range being 4.7-22.0 ng/dL in children and 8.4-20.5 ng/dL in adults. This simple and accurate enzyme-linked immunosorbent assay method is useful for diagnosing biotin deficiency.

Abstract
The objective of the study was to investigate whether an infant formula supplemented with galacto-oligosaccharides (GOS; OM55N) was able to stimulate the growth of indigenous bifidobacteria and to establish microbiota similar to that of breastfed infants. A randomised, double-blind, placebo-controlled trial was performed using 35 healthy term infants (31-54 days of age; 42±6 days) to determine whether infant formula with 0.3 g/dl GOS (OM55N) stimulated the growth of bifidobacteria in the infants’ guts. At the trial onset and 2 weeks after, the infants’ faecal samples were examined for microbiota composition (bacterial abundance and α-diversity) and faecal characteristics. Among the 35 infants, 5 were withdrawn and 8 were excluded from the final evaluation before breaking the blinding since the indigenous bifidobacteria were not detected at the trial onset. After 2 weeks, the abundance of Bifidobacteriaceae was significantly increased in the GOS feeding group compared to the control (+11.6±24.1% vs -3.9±13.0%; P=0.043). The Shannon index, which accounts for both abundance and evenness of the present species, was significantly decreased with GOS supplementation (-0.1±0.4 vs +0.4±0.4; P=0.014). Faecal characteristics such as pH and organic acids were similar in both groups, with no statistical differences. No adverse side effects related to the formula consumption were reported. Although the concentration of GOS was relatively low, the infant formula with GOS increased the abundance of bifidobacteria and resulted in a reduced α-diversity of the microbiota.

Abstract
BACKGROUND Given that nutritional biotin deficiency in Japanese infants has been reported, a straightforward method for estimating biotin level is needed. The biotin content in infant formula, breast milk, and the sera of infants fed with various types of formula were measured using avidin-binding assay. METHODS A commercially available ELISA kit was used for the measurement of biotin in 54 types of formula, including hydrolysate formulas for milk allergy, as well as in breast milk and in the sera of 27 infants fed with these formulas. RESULTS The biotin content reached the recommended value in only five formulas. All of the hydrolysate formulas and more than half of the special formulas contained biotin <0.1 μg/dL. Serum biotin was low in infants fed only with the hydrolysate formulas, and one of them had alopecia related to biotin deficiency. CONCLUSION While many were asymptomatic, infants fed with formulas lacking biotin are at risk of developing symptomatic disease. The addition of biotin to breast milk substitutes was finally approved in the middle of 2014, however pediatricians in Japan should still be vigilant with regard to nutritional biotin deficiency in infants for the time being.

Abstract
To understand the efficiency change of the extracellular photosensitization reaction by the external factor in myocardium interstitial space, we studied the efficiency change of the extracellular photosensitization reaction caused by talaporfin sodium binding with serum proteins under various serum proteins concentrations and temperature conditions. Talaporfin sodium Q band absorbance was measured with various albumin concentrations and the cell survival rate was measured by WST assay in the same conditions. The talaporfin sodium binding ratio with albumin, high-density lipoprotein, and low-density lipoprotein were measured by talaporfin sodium absorbance measurement after the ultrafiltration. The albumin concentration affects the photocytotoxicity strongly when the albumin concentration was over 2.1 mg/ml in the case of the extracellular photosensitization reaction. It would be useful to measure the peak wavelength in Q band absorbance was suggested to know the albumin concentration and the photocytotoxicity efficiency to realize the safety treatment. The binding ratios with high-density lipoprotein and low-density lipoprotein were decreased with the solution temperature rise from 17°C to 37 °C and the photocytotoxicity was increased with temperature rise from 17°C to 37°C involving this binding ratio change. It would be important to maintain the target organ temperature during the photosensitization reaction to keep the photosensitization reaction efficiency.

Abstract
BACKGROUND The Wisteria floribunda agglutinin-positive human Mac-2-binding protein (WFA(+) -M2BP) is a new liver fibrosis glycobiomarker with unique fibrosis-related glyco-alteration. WFA(+) -M2BP is also a useful surrogate marker for the risk of developing hepatocellular carcinoma and for the liver functional reserve. AIM To evaluate the diagnostic ability of WFA(+) -M2BP for liver fibrosis in the clinical setting and the clinical utility of WFA(+) -M2BP for predicting the efficacy of direct-acting anti-viral (DAA) treatment for chronic hepatitis C patients. METHODS The study included 159 genotype 1 hepatitis C patients who received DAA-based treatment (telaprevir or simeprevir) combined with pegylated-interferon alpha plus ribavirin (108 telaprevir- and 51 simeprevir-based triple treatment). The relation between baseline serum WFA(+) -M2BP and treatment efficacy was evaluated. RESULTS The serum WFA(+) -M2BP level significantly increased with the progress of liver fibrosis. Area under the receiver operating characteristic curve analysis identified 2.17 as the cut-off index (COI) for WFA(+) -M2BP for diagnosing advanced fibrosis. The sustained virological response (SVR) rate was significantly, negatively correlated with the serum WFA(+) -M2BP level. Multiple logistic regression analysis found a low serum WFA(+) -M2BP level (<2.17 COI) to be independently associated with SVR (odds ratio, 4.35, P = 0.027). Even for prior nonresponders and patients with the interleukin-28B minor allele or histological advanced fibrosis, treatment outcome was favourable for patients with a low serum WFA(+) -M2BP level. CONCLUSION Serum WFA(+) -M2BP is a non-invasive liver fibrosis marker useful for predicting the efficacy of DAA-based triple therapy for chronic hepatitis C patients.

Abstract
Zellweger syndrome, one of the peroxisome biogenesis disorders, is an autosomal recessive disease caused by mutations in PEX genes. It is characterized by severe hypotonia, failure to thrive, psychomotor retardation, liver dysfunction, and sensorineural hearing impairment. Most of the patients with this disease die before the age of 1 year. PEX14 is the 13th PEX gene responsible for peroxisome biogenesis disorders. Thus far, only two patients with PEX14 deficiency have been reported. Here, we report the first case of a Japanese patient with a PEX14 mutation who showed severe hypotonia, psychomotor retardation, demyelination, and developed rickets at the age of 5 months. An increased excretion of 3,6-epoxydicarboxylic acids leads to the diagnosis of Zellweger syndrome and a mutation analysis of PEX14 revealed a homozygous mutation of c.538C>T (p.Q180X). The patient survived for a prolonged period of time but died of liver failure at the age of 46 months.

Abstract
Favourable efficacy and safety profiles for simeprevir in combination with pegylated interferon alpha (PEG-IFNα) and ribavirin (triple therapy) have been shown in clinical trials. This study was carried out to evaluate the effectiveness of simeprevir-based triple therapy for patients with prior telaprevir treatment failure. This multicentre, observational cohort consisted of 345 consecutive Japanese patients infected with HCV genotype 1b, including 20 who had experienced telaprevir-based triple therapy. Amino acid substitutions in the NS3/4A region were identified by direct sequencing at the time of relapse or breakthrough in treatment with telaprevir and at the initiation of treatment with simeprevir. Patients were stratified according to prior response to PEG-IFNα and ribavirin. Of the 20 patients with telaprevir treatment failure, 10 (50.0%) achieved sustained virological response at week 12 after the end of treatment (SVR12). For patients treatment naïve [3/4 (75.0%)] or with prior relapse [1/1 (100%)] or partial response [5/6 (83.3%)] to PEG-IFNα and ribavirin, almost all achieved SVR12, mainly because of the improvement of treatment adherence, especially to direct-acting antiviral agent and ribavirin. However, of the nine patients with prior null response to PEG-IFNα and ribavirin, only one (11.1%) achieved SVR12, despite all having received an adequate treatment dosage, and five (55.6%) achieved rapid virological response. The treatment outcome of simeprevir-based triple therapy for HCV genotype 1b patients with prior telaprevir failure depended on the prior response to PEG-IFNα and ribavirin. For patients with prior null response to PEG-IFNα and ribavirin, retreatment with simeprevir-based triple therapy is not a useful option.

Abstract
We investigated the extracellular photosensitization effect on myocardial cells using talaporfin sodium at various irradiance measuring cell lethality dependence on talaporfin sodium concentration and immediate response of intracellular Ca(2+) as a fundamental study of the application for tachyarrhythmia treatment. The myocardial cell lethality was measured 2 h after the photosensitization reaction by WST assay varying the irradiance from 0.12 to 0.66 W/cm(2). The intracellular Ca(2+) of myocardial cell was observed during and until 10 min after the extracellular photosensitization reaction using fluo-4 AM and a confocal microscope varying the irradiance. The linear increasing behavior of the myocardial cell lethality with talaporfin sodium concentration was similarly obtained in the case of 0.12 and 0.29 W/cm(2) in irradiance. The photocytotoxicity was not obtained in the case of 0.46 and 0.66 W/cm(2) in irradiance. The time response of necrosis occurrence after the beginning of the extracellular photosensitization reaction was decreased with the irradiance increasing. We prospect that it may be caused by oxygen depletion in our in vitro system using 96 well plate since the irradiance and talaporfin sodium concentration were higher comparing the in vitro conditions of the general PDT for cancer.

Abstract
OBJECTIVE To explore the changes in the body weight and height of Menkes disease (MNK) patients treated with long-term copper-histidine. METHODS A survey involving a retrospective review of medical records or summaries of MNK patients was conducted. Patients were 44 males born after 1994, and their feeding method and genetic analysis of the ATP7A gene were reviewed. We compared the data of body weight and height from birth until 6 years between classical MNK patients and the general population obtained from national data and between patients who received early treatment and patients who received late treatment. RESULTS Although five patients who received early treatment reached some developmental milestones, the body weight and height did not differ from patients who received late treatment in the mode of oral nutrition, and were lower in comparison to the national data (<3 percentile). CONCLUSION We reported changes in the body weight and height of MNK patients who received early and late treatment. Although early treatment with copper-histidine had favorable effects on neurological development, it did not result in improvements in body weight and height. We suggest that the establishment of sufficient nutritional support is necessary along with early parenteral copper treatment to improve whole body condition in MNK patients.

Abstract
Thrombocytopenia in patients with chronic hepatitis C may represent an obstacle for the initiation of antiviral treatment. The aim of this study was to evaluate factors predictive of successful pegylated interferon (PEG-IFN) α2b and ribavirin (RBV) treatment for patients with thrombocytopenia with no history of splenectomy or partial splenic embolization. One hundred and fifty-one chronic hepatitis C patients (genotype 1: n = 110, genotype 2: n = 41) with TCP (<100 × 10(9) /L) at baseline were enrolled. Pretreatment variables included interleukin 28B (IL28B) genotype (rs8099917) and homoeostasis model assessment of insulin resistance score (HOMA-IR). The kinetics of haemoglobin and platelets according to the inosine triphosphatase (ITPA) genotype (rs1127354) were investigated. Sustained virological response (SVR) was significantly more frequent in hepatitis C virus (HCV) genotype 2 (65.9%) than in genotype 1 (34.5%) patients (P < 0.0001). Multiple logistic regression analysis of HCV genotype 1 extracted IL28B TT genotype [odds ratio (OR) 5.97, P = 0.006] and HOMA-IR <2.5 (OR 7.14, P = 0.0016) as significant independent pretreatment predictors of SVR. The analyses of HCV genotype 2 showed that HOMA-IR was significantly related to SVR, but IL28B genotype was not. Patients with ITPA CC genotype showed a significant haemoglobin reduction and lower degree of platelets decrease than those with ITPA CA/AA genotypes. The most common reason for premature discontinuation of treatment was the development of hepatocellular carcinoma (n = 8, 5.3%). In conclusion, HOMA-IR is a useful predictor of SVR for patients with thrombocytopenia infected with HCV genotype 1 or 2 treated with PEG-IFNα2b and RBV. The inclusion of IL28B, ITPA genotypes and HOMA-IR adds valuable therapeutic information.

Abstract
BACKGROUND Antiviral treatment is recommended for chronic hepatitis C patients with advanced fibrosis to reduce and prevent cirrhosis-related complications. AIM To evaluate the efficacy and safety of telaprevir (TVR)-based triple therapy for patients with advanced fibrosis in a clinical practice setting. METHODS This prospective, multicentre study consisted of 102 patients with advanced fibrosis (METAVIR score F3-4) who were infected with HCV genotype 1b. All received 12 weeks of TVR in combination with 24 weeks of pegylated interferon (PEG-IFN) α2b and ribavirin (RBV). RESULTS The sustained virological response (SVR) rate was 69.6% (71 of 102). Notably, for treatment-naïve and prior relapse patients the SVR rate was over 80%. Previous treatment response, interleukin 28B polymorphism (rs8099917) and rapid virological response (undetectable HCV RNA at week 4) were independently associated with SVR. To achieve SVR, an adequate dosage of PEG-IFNα2b (≥1.2 μg/kg/week) and RBV (≥7.5 mg/kg/day) is preferable; however, the mean weight-adjusted TVR dosage had little impact on treatment outcome. Although severe blood cytopaenia and a dermatological disorder were frequently found, the rate of discontinuation due to adverse effects was 12.7%. The inosine triphosphatase CC allele (rs1127354) was independently associated with the development of severe anaemia, and lower serum albumin level (<35 g/L) was associated with the occurrence of infection. CONCLUSIONS The great gain in the SVR rate by telaprevir-based triple therapy offsets the problems with adverse effects; thus, it should be considered as a potent treatment protocol for patients with advanced fibrosis, especially for those with treatment-naïve and prior relapse.

Abstract
Release of growth hormone (GH) from the somatotroph is regulated by binding GH-releasing hormone (GHRH) to its cognate receptor (GHRHR), one of the members of the G protein-coupled receptor (GPCR) superfamily. Proteins bound to the carboxy (C)-terminus of GPCR have been reported to regulate intracellular trafficking and function of the receptor; however, no functionally significant protein associated with GHRHR has been reported. We have identified a protein interacting with C-kinase 1 (PICK1) as a binding partner of GHRHR. In vitro binding assay revealed the PDZ-domain of PICK1 and the last four amino acid residues of GHRHR were prerequisite for the interaction. Further, in vivo association of these proteins was confirmed. Immunostaining data of a stable cell line expressing GHRHR with or without PICK1 suggested the C-terminus of GHRHR promoted cell surface expression of GHRHR and PICK1 affected the kinetics of the cell surface expression of GHRHR. Furthermore, cAMP production assay showed the C-terminus of GHRHR is involved in the regulation of receptor activation, and the interaction of GHRHR with PICK1 may influence intensities of the signal response after ligand stimulation. Thus, the interaction of the C-terminus of GHRHR with PICK1 has a profound role in regulating the trafficking and the signaling of GHRHR.

Abstract
Early diagnosis and treatment of acute cellular rejection (ACR) after intestinal transplantation (ITx) is challenging. We report the outcome of three patients: two presented mild ACR improved with steroids. One presented steroid-resistant severe rejection, improved after rabbit anti-thymocyte globulin (r-ATG), but unfortunately died for encephalitis caused by opportunistic infections.

Abstract
Menkes disease (MD) is a genetic neurodegenerative disorder characterized by copper deficiency due to a defect in ATP7A. Standard treatment involves parenteral copper-histidine administration. However, the treatment is ineffective if initiated after two months of age, because the administered copper accumulates in the blood-brain barrier and is not transported to neurons. To resolve this issue, we investigated the effects of a combination therapy comprising copper and disulfiram, a lipophilic chelator, in the macular mouse, an animal model of MD. Seven-day-old macular mice treated subcutaneously with 50 μg of CuCl(2) on postnatal day 4 were used. The mice were given a subcutaneous injection of CuCl(2) (10 μg) with oral administration of disulfiram (0.3mg/g body weight) twice a week until eight weeks of age, and then sacrificed. Copper concentrations in the cerebellum, liver, and serum of treated macular mice were significantly higher than those of control macular mice, which received only copper. Mice treated with the combination therapy exhibited higher cytochrome c oxidase activity in the brain. The ratios of noradrenaline and adrenaline to dopamine in the brain were also increased by the treatment, suggesting that dopamine β-hydroxylase activity was improved by the combination therapy. Liver and renal functions were almost normal, although renal copper concentration was higher in treated macular mice than in controls. These results suggest that disulfiram facilitates the passage of copper across the blood-brain barrier and that copper-disulfiram combination therapy may be an effective treatment for MD patients.

Abstract
The clinical and biochemical effects of disulfiram were evaluated in three boys with the disorders characterized by copper deficiency due to the defect of ATP7A. Two suffered from Menkes disease (MD) and one from occipital horn syndrome. Disulfiram was orally given, in addition to a parenteral administration of copper-histidine in the case of MD patients. Serum levels of copper and ceruloplasmin slightly increased in one MD patient, and he showed favorable emotional expression and behavior more often than before according to his caretakers. However, no obvious changes were observed in the other two patients. Serum ratios of noradrenaline to dopamine, and adrenaline to dopamine, which are thought to be the indicators of dopamine β-hydroxylase activity, one of the copper requiring enzymes, were unaltered after disulfiram treatment. No adverse effects were recognized during the treatment period in all patients. Although the major improvement was not observed clinically or biochemically by disulfiram treatment so far, the trial will be continued to see the possible effects in these disorders with copper transport defect.

Abstract
We report 2 patients with lung cancer accompanied by active pulmonary tuberculosis. Case1 was a 82-year-old woman with stage I A bronchioloalveolar carcinoma and tuberculosis in right upper lobe. Right upper lobectomy was performed after the histological diagnosis of lung cancer by intraoperative frozen section. Case2 was a 69-year-old man with papillary adenocarcinoma in right lower lobe and tuberculosis in bilateral upper lobe. Partial resection in right lower lobe was performed for diagnosis of lung cancer. Smear-positive tuberculosis was diagnosed by sputum examination after the operation. Post-operative anti-tuberculosis chemotherapy was added in both patients.

Abstract
Combined 17alpha-hydroxylase/17,20-lyase deficiency is caused by a defect of P450c17 that catalyzes both 17alpha-hydroxylase and 17,20-lyase reactions in adrenal glands and gonads. In the present study, we analyzed the CYP17A1 gene in a Japanese girl with 17alpha-hydroxylase/17,20-lyase deficiency. The patient was referred to us for clitoromegaly at the age of 3 years. The karyotype was 46,XY. The patient was diagnosed as having 17alpha-hydroxylase/17,20-lyase deficiency based on the clinical and laboratory findings. Analysis of the CYP17A1 gene revealed a compound heterozygous mutation. One mutation was a deletion of codon 53 or 54 encoding Phe (TTC) in exon 1 (DeltaF54) on a maternal allele, which has been previously shown to partially abolish both 17alpha-hydroxylase and 17,20-lyase activities. The other was a novel missense mutation resulting in a substitution of Asn (AAC) for His (CAC) at codon 373 in exon 6 (H373N) on a paternal allele. Functional expression study demonstrated that the H373N mutation almost completely eliminates enzymatic activity. Previous studies have demonstrated that replacement of histidine by leucine at position 373 causes complete loss of both 17alpha-hydroxylase and 17,20-lyase activities with a defect in heme binding due to a global alteration of P450c17 structure, indicating the importance of H373 for P450c17 structure and function. Together, these results indicate that the patient is a compound heterozygote for the DeltaF54 and H383N mutations and that these mutations inactivate both 17alpha-hydroxylase and 17,20-lyase activities and give rise to clinically manifest combined 17alpha-hydroxylase/17,20-lyase deficiency.

Abstract
BACKGROUND AND PURPOSE Dentatorubral-pallidoluysian atrophy (DRPLA) is a hereditary spinocerebellar degeneration caused by expansion of a trinucleotide CAG repeat encoding a polyglutamine tract in a disease protein atrophin-1. The clinical features include ataxia, choreoathetosis, and dementia, which result from neural degeneration caused by the mutant atrophin-1. METHODS We performed skin biopsy in two patients with DRPLA. RESULTS We found multiple clear cells in the epidermis, which were positive for proteins containing an expanded polyglutamine stretches. The clear cells were p63 (+), S-100 (-), and cytokeratin 20 (-), showing that they were keratinocytes. Negative or weak signals of pan-cytokeratin were consistent with the finding of decreased tonofilaments at the electron microscopic level. CONCLUSIONS The presence of clear keratincoytes showed that the mutant proteins interfered in cellular functions not only in neural cells but also in keratinocytes. The skin is accessible by biopsy, making it important in the diagnosis. Furthermore, the polyglutamine staining in the skin may be useful for evaluation of therapeutic modalities for DRPLA and other polyglutamine diseases.
