Papel da eritropoetina recombinante humana sobre o metabolismo dos carboidratos, paratormônio, cálcio iônico, zinco, prolactina e níveis pressóricos em renais crônicos tratados com hemodiálise

Objective: To evaluate the influence of recombinant human erythropoietin (Epho) on carbohydrate metabolism, parathyroid hormone, calcium ionic, zinc, prolactin and blood pressure (BP) in chronic renal failure treated by hemodialysis. Methods: Ten patients in hemodialysis were followed during 24 weeks in two phases: 12 weeks pre-Epho (BP was measured pre and post hemodialysis sessions) and 12 weeks post-Epho (BP was measured as above and also the blood levels of glucose, insulin, parathyroid hormone, calcium ionic, prolactin, and zinc). Results: Patients were 39.8±8.5 y, 50% males. Hematocrit and hemoglobin presented a significant increase four weeks after Epho (22.3±2.3 to 28.1±2.6% and 7.4±0.8 to 9.4±0.9 g/dL, p<0.05). BP (mmHg) and weight pre-Epho: 158±99 and 59±13 (before hemodialysis), 147±96 and 55±13 (after hemo) and post-Epho: 161±100 and 59±13 (before hemo) 155±101 and 56±12 (after hemo) were all not statistically different in any moment. There are also no difference pre and post-Epho in fast glucose (91.8±6.5 and 90.8±6.1 mg/dL, p>0.05), parathyroid hormone (341.4±249.3 and 515.7±310 pg/ mL), calcium ionic (3,66±0.63 and 3.76±0.45 mmol/L), prolactin (males: 327±144.1 and 298.1 ±145.2 μg/mL; females: 666.2±426.6 and 659±395.3 μg/mL) and zinc (median of 0.73 and 0.71 μg\L). Basal insulin was lower after Epho (median of 9.1 to 3.8 μg/mL, p<0.05). Conclusion: These data suggest that recombinant human erythropoietin was effective to improve the anemia and the carbohydrate metabolism in patients with chronic renal failure treated by hemodialysis. © Copyright Moreira Jr. Editors.

Avaliação da função glomerular de cães sadios e nefropatas sob estimulação dopaminérgica

Dopamine is an endogenous compound widely used in intensive care. It has a broad spectrum of action, on the cardiovascular system and urinary tract. Increased glomerular filtration rate, renal blood flow and fractional excretion of sodium and phosphorus are expected renal effects in normal individuals, but are poorly explored in veterinary medicine. This study was conducted to evaluate the glomerular function of dogs with renal disease submitted to continuous infusion of dopamine. Different doses of dopamine were administered in healthy and nephropathic dogs. Laboratory evaluations of creatinine clearance and urinary protein/creatinine ratio were performed during and after treatments. Creatinine clearance showed dose-dependent increase in healthy dogs. In dogs with renal disease, the dose of 1μg/kg/min GFR increased slightly, without changing the urine P/C and blood pressure, while the dose of 3μg/kg/min increased urinary protein excretion.

Congenital diaphragmatic Bochdaleck hernia: Case report

Congenital diaphragmatic Bochdaleck hernia is an anatomical defect of the diaphragm, which allows protrusion of abdominal viscera into the chest, causing serious pulmonary and cardiac complications in the neonate. In this study we aimed to present a case of congenital Bochdaleck hernia. We investigated a 40 weeks old child, with a pregnancy carried out in a public hospital in Passo Fundo, Rio Grande do Sul, Brazil. We suggest that if diagnosis occurs in the prenatal period, the prognosis of this disease improves. As a consequence, it allows the parity of the fetus to occur in a higher complexity center, optimizing the chances of survival. © 2012 Lava et al.; licensee BioMed Central Ltd.

Treatment of adriamycin-induced nephropathy with erythropoietin and G-CSF

Background: Granulocyte colony-stimulating factor (G-CSF) and Erythropoietin (EPO) are known to stimulate the growth and differentiation of progenitor cells to prevent acute renal injury. This study aimed to assess the use of growth factors to mobilize stem cell in a mouse model of adriamycin-induced chronic kidney disease. Methods: All animals were injected with adriamycin for kidney injury and allocated into three treatment groups (G-CSF, EPO and G-CSF + EPO), and a control group (adriamycin alone). Results: Number of atrophic sites, glomerulosclerosis rate and interstitial fibrosis severity score were assessed in all groups. In all treatment groups, histologic parameters did not significantly differ, but were lower than in the control group (P<.001). Scal and CD34 expressions among treatment groups showed no statistically significant difference, but were higher than in the control group (P<.0001). CD105 expression was higher in EPO and G+EPO as compared to G-CSF and the control group (P<.0001), with no statistically significant difference between the latter two groups (P = NS). Conclusion: G-CSF and EPO had a histologic protective effect, while treatment with EPO + G-CSF had no additive effects in a model of adriamycin-induced chronic kidney disease. © 2013 Societá Italiana di Nefrologia.

Effect of dialysate sodium reduction on body water volume, blood pressure, and inflammatory markers in hemodialysis patients - A prospective randomized controlled study

Accumulating evidence suggests an association between body volume overload and inflammation in chronic kidney diseases. The purpose of this study was to evaluate the effect of dialysate sodium concentration reduction on extracellular water volume, blood pressure (BP), and inflammatory state in hemodialysis (HD) patients. In this prospective controlled study, adult patients on HD for at least 90 days and those with C-reactive protein (CRP) levels ≥ 0.7 mg/dL were randomly allocated into two groups: group A, which included 29 patients treated with reduction of dialysate sodium concentration from 138 to 135 mEq/L; and group B, which included 23 HD patients not receiving dialysate sodium reduction (controls). Of these, 20 patients in group A and 18 in group B completed the protocol study. Inflammatory, biochemical, hematological, and nutritional markers were assessed at baseline and after 8 and 16 weeks. Baseline characteristics were not significantly different between the two groups. Group A showed a significant reduction in serum concentrations of tumor necrosis factor-α, and interleukin-6 over the study period, while the BP and extracellular water (ECW) did not change. In Group B, there were no changes in serum concentrations of inflammatory markers, BP, and ECW. Dialysate sodium reduction is associated with attenuation of the inflammatory state, without changes in the BP and ECW, suggesting inhibition of a salt-induced inflammatory response.
