Microalbuminuria (MAU) is a predictor of cardiovascular mortality in patients with diabetes mellitus (DM) and hypertension (HTN) and also in an unselected population. The American Diabetes Association (ADA) and the National Kidney Foundation (NKF) define MAU as an albumin/creatinine ratio (ACR) between 30 and 300 μg/mg in both men and women. Aim: To evaluate the possible relationship among MAU, HTN and gender and ethnicity in Brazilian nondiabetic primary hypertensive patients. design: Population-based study. Participants: Ninety-eight men and women, seventy-two black and twenty-six white nondiabetic primary hypertensive patients aged 20 years or older were selected. Forty healthy individuals, paired according to age, gender, and ethnics were used as controls. Methods: Early-morning midstream urine was used. Urinary albumin was spectrophotometrically measured with Coomassie Brillant Blue G-250. Creatinine was determined by a method based on Jaffe’s reaction. ACR (μg albumin/mg creatinine) was calculated. Data are expressed as medians. Results: ACR level was significantly higher in 98 hypertensive patients (38.00) than in 40 control individuals (23.00) (P demonstrating that the ACR level is significantly higher in men than in women. The lack of an ethnicity effect supports what was already asserted, namely, that in Brazil, at an individual level, color, as determined by physical evaluation, is a poor predictor of genomic African ancestry, as estimated by molecular markers.

Grade 4 febrile neutropenia and Fournier's Syndrome associated with triple therapy for hepatitis C virus:A case report

引用

World Journal of Hepatology 2014年第6期6卷 448-452页

作者： Kelly Cristhian Lima Oliveira Emili de Oliveira Bortolon Cardoso Suzana Carla Pereira de souza Flávia souza Machado Carlos Eduardo Alves Zangirolami Alecsro Moreira Giovanni Faria silva Cássio Vieira de Oliveira Division of Gastroenterology Department of Internal MedicineBotucatu School of Medicine18618-970 Sao PauloBrazil

The use of triple therapy for hepatitis C not only increases the rate of sustained virological responses compared with the use of only interferon and ribavirin(RBV) but also leads to an increased number of side effects. The subject of this study was a 53-year-old male who was cirrhotic with hepatitis C virus genotype 1 A and was a previous null non-responder. We initially attempted retreatment with boceprevir(BOC), Peginterferon and RBV, and a decrease in viral load was observed in the 8th week. In week 12, he presented with disorientation, flapping, fever, tachypnea, arterial hypotension and tachycardia. He also exhibitedleucopenia with neutropenia. Cefepime and filgrastim were initiated, and treatment for hepatitis C was suspended. A myelogram revealed hypoplasia, cytotoxicity and maturational retardation. After 48 h, he developed bilateral inguinal erythema that evolved throughout the perineal area to the root of the thighs, with exulcerations and an outflow of seropurulent secretions. Because we hypothesized that he was suffering from Fournier's Syndrome, treatment was replaced with the antibiotics imipenem, linezolid and clindamycin. After this new treatment paradigm was initiated, his lesions regressed without requiring surgical debridement. Triple therapy requires knowledge regarding the management of adverse effects and drug interactions; it also requires an understanding of the importance of respecting the guidelines for the withdrawal of treatment. In this case report, we observed an adverse event that had not been previously reported in the literature with the use of BOC.
