Glycated Albumin Predicts the Risk of Mortality in Type 2 Diabetic Patients on Hemodialysis: Evaluation of a Target Level for Improving Survival

Glycated albumin (GA) is considered a more reliable marker than glycated hemoglobin (HbA1c) for monitoring glycemic control, particularly in diabetic hemodialysis patients. We investigated the associations of GA, HbA1c, and random serum glucose levels with survival, and evaluated possible targets for improving survival in diabetic hemodialysis patients. In this prospective, longitudinal, observational study, we enrolled 90 diabetic hemodialysis patients across six dialysis centers in Japan. The median duration of follow‐up was 36.0 months (mean follow‐up, 29.8 months; range, 3–36 months). There were 11 deaths during the observation period. GA was a significant predictor for mortality (hazard ratio, 1.143 per 1% increase in GA; 95% confidence interval, 1.011–1.292; P = 0.033), whereas HbA1c and random glucose levels were not predictors for mortality. Receiver operating characteristics curve analysis showed that the cutoff value of GA for predicting the risk of mortality was 25%. In the Kaplan–Meier analysis, the cumulative survival rate was significantly greater in patients with GA ≤25% than in patients with GA >25%. GA predicted the risk of all‐cause and cardiovascular mortality in diabetic hemodialysis patients. Our results suggest that GA ≤25% is an appropriate target for improving survival in diabetic hemodialysis patients.     

A patient with esophageal cancer with bone metastasis who achieved pain relief with repetitive administration of strontium-89 chloride

A 75-year-old woman was diagnosed with esophageal cancer with difficulty in swallowing. She had a past history of rheumatoid arthritis, scleroderma, interstitial pneumonia, angina pectoris (with coronary artery bypass surgery) and arrhythmia (with pacemaker implantation). She refused surgery, and chemotherapy and radiotherapy were not performed because of the high risk accompanied with multiple comorbidities. She received proton therapy at another hospital and the primary lesion shrank. Bone metastasis in the thoracic vertebrae was diagnosed 10 months after diagnosis of esophageal cancer. Non-steroidal anti-inflammatory drugs and zoledronic acid were administered for back pain. Oxycodone was also administered but discontinued due to nausea. After strontium-89 (⁸⁹Sr) chloride administration, her back pain was relieved. ⁸⁹Sr was administered five times every 3 months, and the pain did not worsen until her death due to pneumonia 2 years after diagnosis of esophageal cancer. ⁸⁹Sr was effective for pain from bone metastasis of esophageal cancer, and its repeated administration was safe.     

Combination therapy with single incision laparoscopic surgery and double-balloon endoscopy for small intestinal bleeding: report of three cases

The clinical introduction of double-balloon endoscopy (DBE) has brought about a revolution in the diagnosis and the treatment of diseases of the small intestine. DBE allows not only direct observation of the entire small intestine, but also interventional therapies, tissue sampling and India ink marking (tattooing). Single incision laparoscopic surgery (SILS) was developed from conventional laparoscopic surgery to further reduce the degree of invasiveness. SILS requires only one umbilical incision, thus resulting in almost scarless surgery. This report presents three cases of small intestinal bleeding successfully treated by SILS following tattooing under DBE. The average operative time was 67 min and average blood loss was 5 ml. All patients immediately recovered without any complications. SILS, in conjunction with presurgical tattooing by DBE for small intestinal bleeding is considered to be an ideal approach in terms of minimal surgical trauma and aesthetics.     

Antibody‐mediated rejection after ABO‐incompatible pediatric living donor liver transplantation for propionic acidemia: A case report

We herein present the case of a four‐yr‐old boy with PA who developed AMR after ABO‐incompatible LDLT despite undergoing B cell desensitization using rituximab. Although the CD19+ lymphocyte count decreased to 0.1% nine days after the administration of rituximab, he developed a high fever which was accompanied by arthralgia due to a streptococcal infection 13 days after rituximab prophylaxis. After the clearance of the infection, he underwent ABO‐incompatible LDLT 36 days after the administration of rituximab. The CD19+ lymphocyte count just prior to LDLT was 1.2%. He developed AMR five days after LDLT, and the antidonor‐type IgM and IgG antibody titers increased to 1:1024 and 1:1024, respectively. He was treated by plasma exchange, IVIG, steroid pulse therapy, and rituximab re‐administration; however, his liver dysfunction continued. Despite intensive treatment, he died due to complicated abdominal hernia, acute renal failure, and ARDS. This case suggests that a streptococcal infection may induce the activation of innate immune responses; thus, additional desensitization therapy should be considered prior to ABO‐incompatible LDLT if B cell reactivation is suspected.     

An initial trial of quantitative evaluation of autoimmune pancreatitis using shear wave elastography and shear wave dispersion in transabdominal ultrasound

Background/ObjectivesWe aimed to examine therapeutic efficacy and prognosis prediction of autoimmune pancreatitis (AIP) using shear wave elastography (SWE) and shear wave dispersion (SWD) in transabdominal ultrasound (US).MethodsThe subjects were 23 patients with diffuse type 1 AIP who underwent SWE and SWD, and 34 controls with a normal pancreas. Elasticity and dispersion were defined as the pancreatic elastic modulus (PEM) and dispersion slope, respectively. PEM and dispersion slope were compared between AIP and control cases, and the short-term therapeutic effect and long-term prognosis were examined.ResultsPEM (30.9 vs. 6.6 kPa, P < 0.001) and dispersion slope (15.3 vs. 13.0 (m/sec)/kHz, P = 0.011) were significantly higher in AIP cases than in controls. Among the 17 AIP patients followed-up in two weeks after treatment, these parameters were 12.7 kPa and 10.5 (m/sec)/kHz with median decrease rate of 37.2% and 32.8%, respectively, which were significantly higher than the change in the size of pancreatic parenchyma (14.4%, P = 0.026). Fourteen of these subjects were followed up for >12 months, during which 2 had relapse; diabetes improved in 5 and worsened in 2; in 60% of cases, the pancreatic parenchyma was atrophied. The % change in PEM after two weeks was tended to be higher in non-atrophy cases.ConclusionSWE and SWD measurement in US may be useful for quantitative assessment of AIP and evaluation of short-term treatment efficacy.     

Murine colon carcinoma cells engineered to produce human interleukin-2 induce tumor-specific anti-tumor response

Murine colon carcinoma cells (colon 26) transduced by a retrovirus vector with the human interleukin-2 (IL-2) cDNA were studied for their tumorigenicity. Although cell growth in vitro was not affected by integration of the IL-2 gene, s.c. tumors of IL-2-producing colon 26 cells (H2) in syngeneic mice regressed spontaneously after producing small masses. Histological examination of the sites of tumor rejection revealed predominant infiltration of macrophages around the tumor necrotic mass. Subsequent challenge with parent colon 26 cells, but not with Meth A cells (fibrosarcoma of the same genetic background), did not result in tumor formation in mice which had been protected against H2 cells. Inoculation of H2 cells into syngeneic nude mice resulted in tumors with a retarded growth rate. Taken together, T cell-dependent, tumor-specific immunity is obtained by local IL-2 secretion around colon tumors, and this experimental animal model gives us a clue(s) for investigating host anti-tumor responses by cytokine production. © 1996 Wiley-Liss, Inc.     

Delayed DNA Synthesis Induced by 3-Aminobenzamide in Partially Hepatectomized Liver of Rats

The possibility of poly(ADP-ribosyl)ation playing a role during liver regeneration induced by partial hepatectomy (PH) in vivo was examined. When rats were given an i.p. injection of 3-antinobenzamide (ABA) at a dose of 600 mg/kg body weight 12 h after PH, the levels of DNA synthesis at 20 h after PH were significantly reduced. The time course of DNA synthesis in regenerating liver was significantly delayed in the ABA-treated group. Enzymatic assay revealed the activity of poly-(ADP-ribose)polymerase (PADPRP) in controls to be increased in parallel with the increase of DNA synthesis induced by PH. This increase in PADPRP activity was delayed and very much weaker after ABA treatment. The results thus suggested that poly (AUP-ribosyl)ation might play an important role in DNA synthesis during liver regeneration in vivo.
