    ABSTRACT: A C825T polymorphism of the gene encoding the G-protein beta3 subunit (GNB3) is associated with increased intracellular signal transduction. We know that this C825T polymorphism may influence hypertension and obesity. In whites, the C825T polymorphism has been reported to induce hypertension, obesity, and diabetic nephropathy. Thus, we investigated how genetic variation in the GNB3 gene is associated with hypertension, obesity, insulin resistance, diabetes, diabetic complications, and diabetic therapies in 427 Japanese subjects with type 2 diabetes mellitus and in 368 Japanese subjects who underwent general health examinations. The frequency of the GNB3 gene polymorphism was 0.48 and 0.47 in subjects with diabetes and in those who had general health examinations, respectively. The amount of hyperlipidemia of the CT allele was significantly lower than the amount in the CC allele in the Japanese subjects with diabetes. Our results suggest that the C825T polymorphism influences lipid metabolism and is not associated with hypertension, obesity, insulin resistance, diabetes, diabetic complications, or diabetic therapies.

    ABSTRACT: A 69-year-old man was admitted with a large elastic mass in the upper abdomen. Computed tomography revealed a massive tumor in contact with the liver and gastrointestinal endoscopy revealed a gastric adenocarcinoma. He developed acute renal failure with massive proteinuria and died with a marked enlargement of the tumor. Autopsy revealed a tumor located in the lesser omentum. The tumor was considered to be a Gastrointestinal Stromal Tumor (GIST) because it was positive for c-kit. In addition, crescent formations and immune complexes in glomeruli were observed. We report the first case of GIST complicated by rapidly progressive glomerulonephritis and gastric carcinoma.

    ABSTRACT: 維持血液透析症例における二次性副甲状腺機能亢進症に対する22-oxacalcitrlol (OCT) の投与量および骨代謝に与える影響を, intact-PTH (iPTH) で層別して検討した. 対象は金沢大学およびその関連施設の714症例より無作為に抽出したiPTHが150pg/mL以上, 血清補正Caが11mg/dL未満かつCa×P積が70mg2/dL2以下の59例 (男性40例, 女性19例, 年齢57.4±15.4歳) であり, iPTHにより3層 (I:150pg/mL以上300pg/mL未満, II: 300pg/mL以上500pg/mL未満, III:500pg/mL以上) に分類し, 各層それぞれ経口ビタミンD3 0.25μg/日 (IA), OCT 2.5μg (IB, IIA), 5μg (IIB, IIIA), 10μg (IIIB) 週3回の2群に分類した. 治療開始前, 治療開始4, 12週後および最終観察時 (平均19.7±7.8か月) での治療効果および骨形成マーカーの検討を行った. 血清iPTHは437±31pg/mLより最終観察時には256±28pg/mLへと低下した (p<0.001). OCT高用量投与群のiPTH値は治療開始4週後で有意に低下したが, III層では血清Caが有意に上昇した. 治療開始12週後ならびに最終観察時でのiPTHおよび血清Caには各層の2群間に差はなかった. 骨形成マーカーの検討では, 治療前III層のALP, 骨型ALP (BAP) およびオステオカルシン (BGP) はI層に比し高値であり, 治療開始12週後にはBAP, BGPの改善を認め, 最終観察時の平均ALP値は各層とも正常化した. 試験期間中, 血清リン値の変動は認められなかった. 以上より, iPTHによる経口ビタミンD3あるいはOCTを用いた層別治療アルゴリズムは, 急激な血清Ca値の上昇を招くことなくiPTHの低下ならびに骨形成マーカーの改善に有効と考えられた.

    ABSTRACT: We describe a type 2 diabetic patient who showed immediate-type allergy against human insulin associated with marked eosinophilia at initial insulin therapy. Three months after initiation of insulin therapy, he noticed itchy skin wheals at the site of the insulin injection. Laboratory data at that time showed marked eosinophilia (2,512 /mm3) and progression of renal dysfunction. Skin test with semisynthetic human insulin and protamine sulfate resulted in local immediate skin reactions such as itchy erythema and wheals. Histopathology of the biopsy specimen from skin showed perivascular infiltration of lymphocytes and numerous eosinophils in the dermis and subcutaneous fat. Although the titer of total IgE antibody was within normal range, that of insulin-specific IgE antibody was high. Insulin administration was discontinued to preserve his insulin secretion, and stable control of his hyperglycemia was obtained by initiating nateglinide treatment (360 mg/day). His itchy skin lesions disappeared within two weeks after cessation of the insulin therapy and both eosinophilia and renal dysfunction gradually improved. Although the widespread use of human insulin in diabetic patients has greatly reduced the incidence of insulin allergy, the possibility of human insulin allergy should be kept in mind when initiating such therapy.

    ABSTRACT: Given that the NcoI polymorphism of the tumor necrosis factor-β (TNF-β) gene has been shown to be associated with tumor necrosis factor-α (TNF-α) secretory capacity, we know that this TNF-β gene polymorphism may influence insulin resistance. In Caucasians, 2 polymorphisms of the TNF-α promoter region (positions −308 and −238) have been reported to be associated with insulin resistance. Thus, we investigated how genetic variation in the TNF-β and TNF-α genes was associated with insulin resistance in 211 Japanese men. The frequency of the TNF-β gene polymorphism was 0.41, and insulin resistance, estimated by homeostasis model assessment (HOMA), was significantly lower in variant homozygotes versus wild-type allele. The frequencies of the −308 and −238 polymorphisms were 0.01 and 0.02, respectively, and these polymorphisms were not associated with insulin resistance. Our results suggest that the TNF-β gene polymorphism decreases insulin resistance, and that the −308 and −238 polymorphisms of the TNF-α promoter region are not a major contributing factor to insulin resistance in Japanese men.

    ABSTRACT: The β2-adrenergic receptor (β2AR), β3AR, or uncoupling protein 1 (UCP1) may play a pathogenic role in obesity. In Swedish Caucasians, a polymorphism at codon 27 (Gln27Glu) of the β2AR gene was shown to be associated with obesity, but no such association was shown for a polymorphism of codon 16 (Arg16Gly). Thus, we investigated whether these polymorphisms contribute to obesity in 210 Japanese men. The frequencies of the Gln27Glu and Arg16Gly polymorphisms were 0.05 and 0.48, respectively, and there was no association with obesity. A strong linkage disequilibrium between the Gln27Glu and Arg16Gly polymorphisms was shown, but there was no apparent additive effect on the clinical or metabolic characteristics. Our results suggest that the Gln27Glu and Arg16Gly polymorphisms of the β2AR gene are not a major contributing factor to obesity in Japanese men.

    ABSTRACT: An alanine to threonine substitution at codon 54 of the fatty acid binding protein 2 (FABP2) gene has been associated with insulin resistance in Pima Indians and with obesity in aboriginal Canadians. We investigated whether this polymorphism contributes to obesity and insulin resistance in 258 Japanese subjects. Thirty-six subjects (13.9%) were homozygous for the Thr54 allele, 106 (41.1%) were heterozygous for the Ala54/Thr54 allele, and 116 (45.0%) were homozygous for the Ala54 allele. The frequency of the Thr54 allele was 0.34 and did not differ significantly between men and women. The incidence of non-insulin-dependent diabetes mellitus (NIDDM) was not different among the three genotypes. The variation at codon 54 of the FABP2 gene was not associated with obesity, hypertension, dyslipidemia, hyperuricemia, or hyperinsulinemia. These results suggest that the polymorphism at codon 54 of the FABP2 gene is not a major contributing factor to obesity and insulin resistance in Japanese subjects.

    ABSTRACT: The Trp64Arg mutation of the β3-adrenergic receptor (β3AR) gene and A to G polymorphism of the uncoupling protein 1 (UCP1) gene are reported to be associated with weight gain, and both have been shown to have an additive effect on weight gain in Caucasians. Racial differences have also been noted in the β3AR mutation; however, the effect of UCP1 polymorphism on body weight is not obvious in the Japanese. Thus, we investigated the association of genetic variations in β3AR and UCP1 genes and the additive effects of these two genes in 214 Japanese men. The frequency of the Trp64Arg allele was 0.19, and serum triglyceride was significantly higher in Arg64 homozygotes versus Trp64 homozygotes. The frequency of the G allele was 0.51, and the body mass index (BMI) was significantly higher in subjects with the G allele (GG homozygotes and AG heterozygotes) versus those without it (AA homozygotes). The β3AR mutation and UCP1 polymorphism were not found to have additive effects, and they were not related to glucose tolerance patterns and insulin resistance. Our results suggest that the β3AR mutation is associated with hypertriglyceridemia and the UCP1 polymorphism may be a weak contributing factor to obesity in Japanese men.

    ABSTRACT: A case of newly diagnosed non-insulin-dependent diabetes mellitus with immediate-type allergy against semisynthetic human insulin is reported. She experienced immediate-type allergy 2 months after initial insulin treatment. A skin test showed that she had allergy against the insulin itself but not the additives. The amino acid sequence of the semisynthetic human insulin was identical to that of endogenous native insulin and, moreover, the patient had not been treated with animal-derived insulin previously, so a structural change to the semisynthetic formulation at the injected subcutaneous site might have antigenicity. An H1 histamine blocker markedly diminished the skin reaction to insulin, and her plasma glucose and glycosylated hemoglobin AIc became well controlled. In summary, we experienced a diabetic patient with human insulin allergy at the time of initial insulin treatment, emphasizing that the possibility of human insulin allergy should be considered whenever a patient is started on insulin therapy.

    ABSTRACT: We present a patient with Cushing's syndrome due to adrenocortical adenoma who developed acute adrenal insufficiency one month after unilateral adrenalectomy. She had received lithium carbonate for five years for manic-depressive psychosis. Drug administration was interrupted for 2 weeks postoperatively and was resumed thereafter. At the adrenal crisis, her serum free T4 and T3 levels were both high and serum TSH was subnormal. The thyrotoxicosis subsided spontaneously within 2 weeks. Serum thyroglobulin was markedly increased during the thyrotoxic state. Tests for antimicrosomal antibodies and antithyroglobulin antibodies remained negative. Examination of an open-biopsy specimen of the thyroid gland showed no evidence of thyroiditis. We considered the transient thyrotoxicosis to be due to lithium-induced thyrotoxicosis. Caution should therefore be exercised in administering lithium carbonate, especially when the patient's adrenal reserve is low, since even a mild degree of thyrotoxicosis can precipitate an acute adrenal crisis.

    ABSTRACT: In order to clarify intraglomerular cellular activation and cytokine involvement in IgA nephropathy, the glomerular expression of MHC class II antigens (HLA-DR and DQ) and cellular proliferative nuclear antigen (Ki-67), and serum γ-interferon (γ-IFN) levels were evaluated in 49 patients with IgA nepropathy. HLA-DR was detected in all but 4 patients in whom glomerular sclerosis was present. HLA-DQ and Ki-67 were observed in 51 and 38% of the patients, respectively. Proteinuria, recent macroscopic hematuria, mesangial proliferation, and extracapillary and endocapillary lesions were more frequent and more severe in HLA-DQ-positive than in HLA-DQ-negative patients. In 10 patients with acute exacerbation, endocapillary lesions and HLA-DQ and Ki-67 expression were present in 70,80 and 88%, respectively. Serum γ-IFN levels were high in the patients (2.0 ± 0.3 U/ml, n = 40), especially during acute exacerbation (3.4 ± 1.1 U/ml, n = 9). Glomerular HLA-DQ and Ki-67 expression correlated with serum γ-IFN levels (r = 0.73, p < 0.01 for HLA-DQ; r = 0.75, p < 0.01 for Ki-67). Renal biopsy specimens taken before and after prednisolone and/or urokinase therapy were available from 4 patients. There was strong reactivity to HLA-DQ in the glomerular tufts of all 4 pretreatment samples. However, HLA-DQ reactivity disappeared after treatment in 3 samples, concomitant with normalization of serum γ-IFN levels. We conclude that serum γ-IFN levels are related to glomerualr HLA-DQ and Ki-67 expression and acute exacerbation in patients with IgA nephropathy. These data suggest that γ-IFN and MHC class II antigens play an important role in the immune-mediated glomerular injury of IgA nephropathy.

    ABSTRACT: The arterial pressure (AP) response to hemodialysis was studied with echocardiography and strain gauge plethysmography in 17 patients with end-stage renal disease; mean AP was unchanged in seven (group A) and was reduced by more than 10 mm Hg in 10 patients (group B). Following dialysis, body weight decreased and heart rate increased equally in both groups. Ejection fraction did not change in the two groups. Left ventricular end-diastolic volume fell by 13 +/- 10% in group A and by 24 +/- 16% in group B. Cardiac index (CI) fell in group B, but remained unchanged in group A. Systemic vascular resistance (SVR) did not change in both groups. The change in mean AP before and after dialysis was significantly correlated with that in Cl (r = 0.49, p less than 0.05), but not with that in SVR. Calf venous pressure-volume curves were not different between the two groups before dialysis. Hemodialysis shifted the curve toward the volume axis for group B but not for group A. These results suggest that hypotension following dialysis is mainly due to the fall in cardiac output, in which increases in venous distensibility play an important role.

    ABSTRACT: A 16-year-old female with acro-renal-ocular syndrome complicated by ventricular septal defect is described. Renal biopsy was performed for the first time in this syndrome, and the results suggested that proteinuria and renal dysfunction were caused by chronic pyelonephritis secondary to malrotation of the kidney and anomalous pelves. Chronic renal failure and hypoplasia of the optic papillae were also observed in the patient's mother, suggesting a participation of heredity in the pathogenesis of the syndrome.

    ABSTRACT: In an attempt to clarify a participation of hepatitis B virus (HBV) in the development of hepatic glomerulopathy in adults, kidney specimens obtained from 151 patients with liver diseases were studied. Although mesangial proliferation was more severe in patients with chronic hepatitis or liver cirrhosis than in those with acute hepatitis, no significant difference was observed between 82 serum hepatitis B surface antigen (HBsAg)-positive (HBV-related group) and 69 negative patients (HBV-nonrelated group). However, double contours of the glomerular capillary walls were observed more often in the former group (18/82, P less than .01), especially in the HBeAg-positive subgroup (8/24, P less than .001), than in the latter (3/69). In addition, glomerular capillary spike formation or a bubblelike appearance was observed in seven patients of the former group. Of these, all five patients examined were HBeAg-positive in their serum. By electron microscopic studies, subendothelial dense deposits and mesangial interpositions were observed more frequently in the HBV-related group, and subepithelial deposits were found only in the HBeAg-positive subgroup. The immunofluorescence study revealed IgA-dominant mesangial deposition in both HBV-related and nonrelated groups. As for the capillary wall deposits, however, IgG was dominant in 13 of the HBV-related group, but only one of the nonrelated group (P less than .01). Furthermore, one patient in the HBV-related group showed capillary wall-dominant HBeAg combined with IgG deposition.(ABSTRACT TRUNCATED AT 250 WORDS)

    ABSTRACT: Based on immunofluorescence findings, 232 patients with IgA nephropathy were classified into two groups; one consisted of 88 patients (38%) with IgA deposits in the glomerular capillary walls together with the mesangial deposits (capillary type), and the other consisted of 144 patients (62%) with deposits confined to the mesangium (mesangial type). Electron microscopic findings revealed dense deposits on the capillary walls (subepithelial, 50%; intramembranous, 65%; and subendothelial, 24%) in 37 of 46 patients with capillary type and six of 47 with mesangial type (P less than .001). Crescent formation observed in greater than or equal to 10% of glomeruli was more frequently found in patients with the capillary type (30/88, 34%) than those with the mesangial type (9/144, 6%) (P less than .01), especially higher in those with subepithelial deposits (15/26, 57%). The capillary type patients showed heavier proteinuria (1.7 +/- 0.2 g/d) than the mesangial type patients (0.6 +/- 0.1 g/d) (P less than .05). Thirteen of the 14 patients in an acute exacerbation phase, manifested by an abrupt increase in urinary protein and development of macroscopic hematuria, showed capillary type IgA deposits. The ratio of patients with normal renal function in the fifth year after apparent onset was lower in the capillary type (74.0%) than in the mesangial type patients (96.9%) (P less than .05). These findings suggest that capillary IgA deposition is closely related to clinical and histologic activities of IgA nephropathy and is considered to be an important factor responsible for the progression of the disease, possibly through crescent formation.

    ABSTRACT: Histological studies were performed on 3 patients with gout and proteinuria measured at 1.0 g a day or more. Light microscopy revealed diffuse thickening of the glomerular capillary walls accompanied by spike formation and bubble-like appearance as well as tophaceous granuloma in the interstitium, tubular atrophy and benign nephrosclerosis. Immunofluorescence technique showed fine granular deposits of IgG and C3 along the glomerular capillary walls together with the renal tubular epithelial antigen (RTE) in 1 patient. Subepithelial dense deposits were also observed by electron microscopy. These findings suggest that the association of membranous nephropathy should be considered in patients with gout having moderate to severe proteinuria and that RTE may be involved in the pathogenesis of subepithelial deposits in gouty membranous nephropathy.
