Transient Worsening of Photosensitivity due to Cholelithiasis in a Variegate Porphyria Patient.

Variegate porphyria (VP) is an autosomal dominant disease caused by mutations of the protoporphyrinogen oxidase (PPOX) gene. This porphyria has unique characteristics which can induce acute neurovisceral attacks and cutaneous lesions that may occur separately or together. We herin report a 58-years-old VP patient complicated with cholelithiasis.

Lower physical activity is a risk factor for a clustering of metabolic risk factors in non-obese and obese Japanese subjects: the Takahata study.

In several countries including Japan, people without obesity but with a clustering of metabolic risk factors (MetRFs) were not considered to have the metabolic syndrome (MetS). Here, we examined whether lifestyle characteristics differed between non-obese and obese subjects with or without a clustering of MetRFs. From a population-based cross-sectional study of Japanese subjects aged ≥ 40 years, 1,601 subjects (age: 61.

Thyroid dysfunction in patients treated with tyrosine kinase inhibitors, sunitinib, sorafenib and axitinib, for metastatic renal cell carcinoma.

Objective: Targeted drugs are generally associated with a lower toxicity than conventional systemic cytotoxic drugs and, thus, are administered for long periods. As a result, unusual adverse effects, including thyroid dysfunction, have become important clinical issues.

Methods: We retrospectively collected the data and compared the incidence and the time of onset of thyroid dysfunction in 33 patients (M/F: 26/7, age: 34-77) with metastatic renal cell carcinoma treated with the small-molecule tyrosine kinase inhibitors (TKIs) sunitinib, sorafenib and axitinib in Yamagata University Hospital, Japan, from 2005 to 2010.

Serum glycerophosphate levels are increased in Japanese men with type 2 diabetes.

Objective: To identify metabolites showing changes in serum levels among Japanese male with diabetes.

Methods: We performed metabolite profiling by coupling capillary electrophoresis with electrospray ionization time-of-flight mass spectrometry using fasting serum samples from Japanese male subjects with diabetes (n=17), impaired glucose tolerance (IGT; n=5) and normal glucose tolerance (NGT; n=14).

Results: Other than the expected differences in characteristics related to abnormal glucose metabolism, the percent body fat was significantly different among subjects with diabetes, IGT and NGT (27.

Higher plasma renin activity is a risk factor for total mortality in older Japanese individuals: the Takahata study.

Plasma renin activity (PRA) is accepted as a marker for increased risk of cardiovascular diseases. However, the association between PRA and total mortality has not been fully explored in a general population. We here examined whether PRA is associated with increased total mortality in a general Japanese population.

Association of the clusterin gene polymorphisms with type 2 diabetes mellitus.

The association of the clusterin (CLU) gene polymorphism (single nucleotide polymorphisms [SNPs] 1-4: rs1532278, rs1532277, rs2279590, and rs2279591, respectively) with type 2 diabetes mellitus was examined using a population of the Funagata study (n [male-female] = 1631 [741:884]; age, 62.0 ± 12.1 years), a Japanese community-based study.

Association of the common fat mass and obesity associated (FTO) gene polymorphism with obesity in a Japanese population.

The association of the FTO gene polymorphism, rs9939609, with obesity was examined using the population of the Takahata study (n (M/F): 2,639 (1,168 / 1,470); age: 63.0 +/- 10.2 years), a Japanese community-based study.

Hemoglobin A1c in predicting progression to diabetes.

The predictive value of hemoglobin A1c (HbA1c) in comparison to fasting plasma glucose (FPG) is evaluated for 5-year incident diabetes (DM), as HbA1c may be more practical than FPG in the screening for DM in the future. Of 1189 non-DM subjects aged 35-89 years old from the Funagata Study, 57 subjects (4.8%) had developed DM on the WHO criteria at 5-year follow-up.

Raised fasting plasma glucose a better predictor of diabetes than the IDF definition of the metabolic syndrome.

Raised FPG was better at identifying future diabetes than either IDF MetS or a constellation of risk factors except for raised FPG with and without abdominal adiposity. This should shed light on a screening program for future DM in Japan.

Association of the Ser326Cys polymorphism in the OGG1 gene with type 2 DM.

The association of the Ser326Cys polymorphism of the 8-oxoguanine glycosylase 1 (OGG1) gene with type 2 diabetes was examined using a Japanese population (n (M/W): 4585 (2085/2500); age: 62.6 +/- 10.9 years).

Expression of BAFF-R and TACI in reactive lymphoid tissues and B-cell lymphomas.

Aims: The receptor for B-cell-activating factor belonging to the tumour necrosis factor family (BAFF-R) and transmembrane activator and calcium modulator and cyclophilin ligand interactor (TACI) have been established as binding molecules to BAFF. The aim of this study was to determine the pathological diagnostic roles and clinical significance of these BAFF-binding receptors in B-cell neoplasms.

Methods And Results: Expression of BAFF-R and TACI was examined immunohistochemically in reactive lymphoid tissues and B-cell lymphomas including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), mantle cell lymphoma (MCL), marginal zone B-cell lymphoma (MZBCL) and plasma cell myeloma (PCM).

Salt consumption-dependent association of the GNB3 gene polymorphism with type 2 DM.

The associations of the C825T polymorphism (rs5443) of the G-protein beta3 subunit (GNB3) gene and eight adjacent single nucleotide polymorphisms (SNPs) with diabetes were examined using a Japanese population (n (M/W): 2956 (1335/1621); age: 63.0+/-10.2 years).

A functional polymorphism of the TNF-alpha gene that is associated with type 2 DM.

To examine the association of the tumor necrosis factor-alpha (TNF-alpha) gene region with type 2 diabetes (DM), 11 single-nucleotide polymorphisms (SNPs) of the region were analyzed. The initial study using a sample set (148 cases vs. 227 controls) showed a significant association of the SNP IVS1G+123A of the TNF-alpha gene with DM (p=0.

Impaired glucose tolerance is a risk factor for stroke in a Japanese sample--the Funagata study.

Impaired glucose tolerance (IGT) is a known risk factor for cardiovascular disease, which includes stroke as well as coronary heart disease (CHD). We investigated whether IGT is a risk factor for stroke. The incidence of stroke and CHD in a cohort population (n = 2938) consisting of participants of the 1990-1997 Funagata study was assessed through interviews with the participants and their family members and reviews of death certificates and residence transfer documents through 2002.

Association of the PIK3C2G gene polymorphisms with type 2 DM in a Japanese population.

The associations of five SNPs (SNPs1-5: A-5468G, A-3333G, C-1794T, C437T and T9148C) of the class II phosphoinositide 3-kinase gamma-subunit (PIK3C2G) gene with type 2 diabetes were examined using a population of the Takahata Study (n (M/W): 2930 (1328/1602); age: 63.3+/-10.2 years), a Japanese community-based study.

A case of primary biliary cirrhosis accompanied with fibrinogen storage disease.

We report the first case of primary biliary cirrhosis (PBC) accompanied by fibrinogen storage disease (FSD). A 50-year-old Japanese woman had been treated for numbness of her right-side extremities for 5 years. Mildly elevated serum levels of alkaline phosphatase and gamma-glutamyl transferase were detected.
