Neonatal asphyxia can cause renal perfusion and dilution disorders and also glomerular filtration abnormality. The purpose of this study was to find renal dysfunction, which caused by neonatal asphyxia. The study was performed by cross sectional for newborn babies with asphyxia based on Apgar score in the first minute. Newborn babies without asphyxia were as control. In both group, the first micturition times were recorded, total urine output in 24 hours were counted, the mean of blood urea and creatinine serum level value examined and also glomerular filtration rate. Statistical analysis has been performed by using Fisher Exact test, Student t test and Wilcoxon Rank Sum test. All of babies in the asphyxiated and non asphyxiated group had the first micturition in 24 hours after delivery. Significant difference of oliguria incidence was found in the asphyxiated group compared to the control group (p<0,05). The mean of blood urea and creatinine serum level was significantly higher in asphyxiated (p<0,05). The mean of glomerular filtration rate in the asphyxiated group was not significantly different to the control group (p>0,05). According to the degree of asphyxia we found significantly different of renal dysfunction (p<0,05). It was concluded that the asphyxia could cause the occurrence of renal dysfunction.

Relevance. Chronic renal failure in patients undergoing radical cystoprostatectomy (RCPE) with various variants of urine derivation is one of the significant problems that requires an interdisciplinary approach. To date, there is an insufficient number of studies comparing a significant decrease in glomerular filtration rate (GFR) between different types of urine diversion after radical cystectomy. Purpose of research. To study glomerular filtration rate (GFR) indicators in patients who underwent radical cystectomy with a heterotopic Bricker reservoir and compare them with similar indicators in patients who underwent radical cystectomy with a « V « shaped heterotopic reservoir. To compare early postoperative complications in patients who underwent radical cystoprostatectomy with the formation of a heterotopic Bricker reservoir and with a modified V-shaped heterotopic reservoir. Materials and methods. To study and compare the dynamics of glomerular filtration rate (GFR), we retrospectively selected patients after radical cystoprostatectomy with heterotypic ileocystoplasty. Patients were divided into two groups: the control group — patients with radical cystoprostatectomy and Bricker ileocystoplasty (n=46), the study group — patients with radical cystoprostatectomy and modified V-shaped heterotopic ileocystoplasty (n=49). Results. At the stage of discharge of patients from the hospital after radical cystoprostatectomy, the level of glomerular filtration rate (GFR) was not statistically significant differences between the study and control group (P=0.3791), including patients with the presence of hydronephrosis (P=0.4664). The difference in glomerular filtration rate (GFR) between the study group and the control group was statistically significant after 6 years of dynamic follow-up. As a result, it can be argued that the dynamics of glomerular filtration rate (GFR) reduction in the study group is lower than in the control group. A particularly significant difference in glomerular filtration rate (GFR) was observed in patients with existing hydronephrosis at the preoperative stage. Conclusion. Modified «V» — shaped heterotopic urine derivation can be recommended for patients who have undergone radical cystoprostatectomy, especially with existing hydronephrosis at the preoperative stage. This method should be used in patients with chronic pyelonephritis against the background of previously diagnosed ureterohydronephrosis, which is a fairly frequent consequence of the invasive nature of the growth of bladder cancer with ureteral obstruction.

ABSTRACT DX-619 is a novel des-fluoro(6)-quinolone with activity against a broad range of bacterial strains, including methicillin-resistant Staphylococcus aureus. The effects of DX-619 on the glomerular filtration rate (GFR) were evaluated because drug-related increases in serum creatinine levels were observed in studies with healthy volunteers. Forty-one healthy subjects were randomized to receive intravenous DX-619 at 800 mg or placebo once daily for 4 days, and the GFR was directly measured by determination of the clearance of a bolus iohexol injection in 33 subjects who completed the study per protocol. DX-619 was noninferior to placebo for the GFR on the basis of a criterion for a clinically significant difference of −12 ml/min/1.73 m2. The mean GFRs on day 4 were 101.1 ± 14.2 ml/min/1.73 m2 and 100.2 ± 15.6 ml/min/1.73 m2 for the volunteers receiving placebo and DX-619, respectively. On day 4 the mean serum creatinine concentration for volunteers receiving DX-619 increased by 30 to 40%, with a corresponding decrease in mean creatinine clearance. Both parameters normalized within 7 days after the cessation of DX-619 treatment. Nonclinical studies suggest that DX-619 increases the serum creatinine concentration by inhibiting excretory tubular transporters. In conclusion, DX-619 administered intravenously at 800 mg once a day for 4 days did not affect the GFR in healthy volunteers. Glomerular toxicity is not expected to present a risk to patients receiving DX-619 in clinical trials, but monitoring of the renal function, with an emphasis on the serum creatinine concentration, is still warranted.

AbstractObjective: Our aim was to determine whether cystatin C level has a superiority to creatinine to assess kidney functions in rapid decreases of glomerular filtration rate due to acute mercury exposure in children. Eight different glomerular filtration rate calculation formulas which have been used creatinine and/or cystatin C were also compared.Methods: Serum urea, creatinine and cystatin C values of 39 mercury exposed children were measured. Glomerular filtration rates were calculated by eight different formulas. Patient group was divided into three subgroups according to mercury levels.Results: Cystatin C and mercury levels of the patients were found significantly different from control group (p<0.001). There was not a significant difference in creatinine and urea values between two groups (p=0.913, p=0.236). There was not a significant difference between patient and control groups in GFR calculations which have been used serum creatinine and height or which have been used urea additional to them (p=0.069, p=0.559, p=0.424, p=0.945, respectively), but there was a significant difference between patient and control groups in GFR calculations which have been used cystatin C only or creatinine, urea and height in addition to this (p<0.001, p<0.001, p=0.042, p<0.001, respectively). In sugroup analysis, cystatin C results and the results of three GFR calculations of four GFR calculations which were used cystatin C were found different in control group according to subgroups but there was not a difference between subgroups.Conclusion: Cystatin C level is a better indicator than creatinine to assess kidney functions in rapid decreases of glomerular filtration rate due to acute exposure of mercury. Formulas using cystatin C gave better results than formulas using creatinine and height in estimation of glomerular filtration rate.

1. The influence of dietary sodium intake on the glomerular filtration rate (GFR/nephron) and potassium and phosphate excretion was examined at three stages of progressive chronic renal failure produced in rats by sequential partial nephrectomies. 2. The adaptive increased sodium excretion per nephron in the control group receiving a constant sodium intake did not occur in the experimental group that had a gradual reduction of dietary sodium in direct proportion to the fall in GFR. 3. Despite the difference in sodium excretion, the increase in GFR/nephron, the daily variation in the amount of potassium and phosphate excreted, the increase in potassium and phosphate excretion per unit nephron, and the plasma potassium and phosphate concentrations were the same in the two groups. 4. The concept of ‘autonomous adaptation’ in chronic renal failure is presented.

Renal and hepatic function were studied during voluntary dives in Weddell seals by measuring the clearance rate of inulin and indocyanine green (ICG). Inulin is cleared exclusively by the kidneys and measures renal glomerular filtration rate (GFR). ICG is cleared by the liver and is blood flow dependent at concentrations used. Studies were conducted from a portable hut with a trapdoor placed over an isolated hole in the sea ice near McMurdo Station, Antarctica. An intravertebral extradural catheter was inserted percutaneously under light anesthesia in subadult seals weighing 130-200 kg. When released into the ice hole, the seals made voluntary dives, but always had to return to breathe. Serial blood samples were taken after single injections of inulin and ICG and analyzed within 24 h. The mean half time (t 1/2) for inulin clearance while resting at the surface was 27.3 +/- 13.0 min (n = 43) and the mean t 1/2 for ICG clearance was 18.3 +/- 7.3 min (n = 23). The mean resting GFR was 3.6 ml X min-1 X kg-1 (range 3.2-3.9, n = 3). Inulin and ICG clearance rates did not change from resting levels during dives shorter than the seal's aerobic dive limit (ADL). Inulin clearance decreased over 90% during dives longer than the ADL, but there was no significant reduction in ICG clearance during dives lasting up to 23 min. It appears that normal renal GFR and hepatic blood flow continue during natural aerobic dives. During dives that exceed the ADL, GFR is reduced but hepatic blood flow may be maintained.

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

Abstract Objective: To describe the frequency of albuminuria in overweight and obese children and adolescents and to relate it to the severity of obesity, pubertal staging, associated morbidities and the glomerular filtration rate. Method: Cross-sectional study including 64 overweight and obese children and adolescents between 5 and 19 years of age. Data collected: weight, height, waist circumference and systemic arterial pressure. Laboratory tests: lipid profile; glycemia and insulin, used to calculate the Homeostasis Model Assessment (HOMA-IR); C-reactive protein; glutamic-pyruvic transaminase and albuminuria in an isolated urine sample (cutoff <30 mg/g). Creatinine was used to calculate the estimated glomerular filtration rate (eGFR, mL/min/1.73 m2). Results: The mean age was 11.6 ± 3.4 years, 32 (50%) and 29 (45.3%) were male and prepubertal. Forty-six (71.9%) had severe obesity. The frequency and median (min/max) of the observed values for albuminuria (> 30 mg/g) were 14 (21.9%) and 9.4 mg/g (0.70, -300.7 mg/g). The mean eGFR was 122.9 ± 24.7 mL/min/1.73 m2. There was no significant correlation between body mass index, pubertal staging, insulin and HOMA-IR with albuminuria values and neither with eGFR. Children with albuminuria tended to have higher values of diastolic blood pressure (75.0 ± 12.2 vs. 68.1 ± 12.4, p = 0.071). Conclusion: Albuminuria, although frequent in children and adolescents with obesity, was not associated with other morbidities and the glomerular filtration rate in these patients.
