The potential use of urinary transferrin, urinary adiponectin, urinary Retinol Binding Protein, and serum zinc alpha 2 glycoprotein levels as novel biomarkers for early diagnosis of diabetic nephropathy: A case-control study.

BACKGROUND AND AIMS: The level of albuminuria is used to evaluate diabetic nephropathy (DN). However, to detect or predict the early stages of DN, better biomarkers are needed. METHODS: This study is a case-control observational study. 80 Egyptians participated in the study: 60 patients with type 2 diabetes mellitus (T2DM) were divided into three groups (20 patients each), and 20 healthy subjects with matched age and gender were used as controls. Demographic and laboratory data were analyzed. An enzyme-linked immunosorbent assay was used to determine the levels of four biomarkers of DN; urinary adiponectin (ADP), urinary transferrin, serum Zinc Alpha 2 Glycoprotein (ZAG), and urinary Retinol Binding Protein (RBP). RESULTS: The levels of DN biomarkers urinary ADP, transferrin, RBP, and serum, ZAG were significantly higher in patients with T2DM than in controls. The ROC curve of the validity of the simultaneous use of all four biomarkers in predicting albuminuria indicates a sensitivity of 90% and a specificity of 90%. The Area Under the Curve (AUC) was 0.948, the 95% confidence interval was 0.998-0.897, and the p-value was 0.001. CONCLUSIONS: In patients with T2DM, urine adiponectin, transferrin, RBP, and serum ZAG concentration may be useful biomarkers in the early diagnosis of DN. A further longitudinal prospective study is required to explore the potential utility of these biomarkers.

Treatment of post-partum haemorrhage with sublingual misoprostol versus oxytocin in women not exposed to oxytocin during labour: a double-blind, randomised, non-inferiority trial.

BACKGROUND: Oxytocin, the standard of care for treatment of post-partum haemorrhage, is not available in all settings because of refrigeration requirements and the need for intravenous administration. Misoprostol, an effective uterotonic agent with several advantages for resource-poor settings, has been investigated as an alternative. This trial established whether sublingual misoprostol was similarly efficacious to intravenous oxytocin for treatment of post-partum haemorrhage in women not exposed to oxytocin during labour. METHODS: In this double-blind, non-inferiority trial, 9348 women not exposed to prophylactic oxytocin had blood loss measured after vaginal delivery at four hospitals in Ecuador, Egypt, and Vietnam (one secondary-level and three tertiary-level facilities). 978 (10%) women were diagnosed with primary post-partum haemorrhage and were randomly assigned to receive 800 microg misoprostol (n=488) or 40 IU intravenous oxytocin (n=490). Providers and women were masked to treatment assignment. Primary endpoints were cessation of active bleeding within 20 min and additional blood loss of 300 mL or more after treatment. Clinical equivalence of misoprostol would be accepted if the upper bound of the 97.5% CI fell below the predefined non-inferiority margin of 6%. All outcomes were assessed from the time of initial treatment. This study is registered with ClinicalTrials.gov, number NCT00116350. FINDINGS: All randomly assigned participants were analysed. Active bleeding was controlled within 20 min with study treatment alone for 440 (90%) women given misoprostol and 468 (96%) given oxytocin (relative risk [RR] 0.94, 95% CI 0.91-0.98; crude difference 5.3%, 95% CI 2.6-8.6). Additional blood loss of 300 mL or greater after treatment occurred for 147 (30%) of women receiving misoprostol and 83 (17%) receiving oxytocin (RR 1.78, 95% CI 1.40-2.26). Shivering (229 [47%] vs 82 [17%]; RR 2.80, 95% CI 2.25-3.49) and fever (217 [44%] vs 27 [6%]; 8.07, 5.52-11.8) were significantly more common with misoprostol than with oxytocin. No women had hysterectomies or died. INTERPRETATION: In settings in which use of oxytocin is not feasible, misoprostol might be a suitable first-line treatment alternative for post-partum haemorrhage.

Postrenal transplant malignancy: Incidence, risk factors, and prognosis.

The newer and potent immunosuppressive agents have successfully reduced the risk of rejection after kidney transplantation, but the development of cardiovascular diseases, infections, and malignancy is major factors limiting their success. Posttransplantation malignancy is the second most common cause of death in renal transplant recipients after cardiovascular disease; it is expected that mortality due to malignancy may become the most common cause of death within the next two decades. This study is designed to evaluate the incidence, risk factors, and types of malignancies occurring after renal transplantation and their impact on patient and graft survival. A total of 2288 patients underwent living donor renal allotransplantation in the Urology and Nephrology Center, Mansoura University, during the period between 1975 and 2011. Among these patients, 100 patients developed posttransplantation malignancy. Patients were categorized into five major groups according to their type of malignancy; Kaposi's sarcoma (KS), non-Kaposi's skin tumors (non-KS), posttransplant lymphoproliferative disorders (PTLD), solid tumors, and genitourinary and reproductive system (GU and RS). Overall, the incidence of cancer in renal transplant recipients was 4%. There were 83 male (83%) and 17 female patients (17%). The most frequent cancer was KS seen in 33 patients (33%). The lowest median time to development of cancer was observed in KS (35 months). The highest median time to development of cancer was observed in PTLD (133 months). The best graft survival was observed in PTLD and the worst in non-KS tumors. The best patient survival was observed in KS and the worst in GU and RS tumors. Azathioprine-based regimen was associated with a higher rate of cancer. The number of patients who died was 65 (65%). Our results indicate that the occurrence of malignancy has an important impact on short- and long-term graft and patient survival.
