Abstract Background and aims. Obese individuals have insulin resistance status assessed in the present study by the HOMA index (“Homeostasis model assessment”). This prospective study assessed renal disorders in the insulin resistance in obese patients. Material and Methods. The study included 73 young obese patients. The assessment included the HOMA index before meal and parameters of renal function (glomerular filtration rate, albuminuria, β2-microglobulinuria). Results. In young obese, insulin-resistance patients, glomerular hyperfiltration and β2-microglobulinuria are found in 77.0 and 93.4% of cases respectively. The albuminuria is noted in some cases, which reduces diagnostic value. Conclusions. In young obese patients with insulin resistance, glomerular hyperfiltration and β2-microglobulinuria are main diagnostic markers of renal dysfunction.

Background:Gout is the most common inflammatory arthritis resulting from a chronic deposition of MSU crystals in the joints and other soft tissues. After the process of repeated tissue damage and repair due to gout, tophi could be formed around the affected joints. Intra-articular tophi may sometimes result in bone destruction, joint deformities, and dysfunction which can adversely affect the patient’s quality of life. Furthermore, early-onset tophaceous gout patients are more likely to develop renal dysfunction, however, few studies have investigated if the presence of tophi is related with the progression of renal dysfunction in gout patients.Objectives:We aimed to compare clinical characteristics of patients with and without tophi at the time of the diagnosis of gout and investigate the effect of tophi on the renal function in gout patients.Methods:Data of 257 patients who were first diagnosed with gout at the Kangwon National University Hospital from January 2012 to December 2018 were retrospectively studied. Patients were divided into 2 groups according to the presence of tophi at the diagnosis. We compared clinical characteristics and the progression of renal dysfunction between the two groups.Results:Of all patients, 66 (25.5%) initially presented with tophi. Patients with tophi were older, had a longer duration of symptoms, and had a higher prevalence of multiple joint involvement than those without tophi. The decline in the eGFR was more prominent in patients with tophi than in those without (-4.8±14.5 ml/min/1.73m2vs. -0.7±11.9 ml/min/1.73m2, respectively; P=0.039). In multivariate logistic regression analysis, a prolonged symptom duration (odds ratio [OR], 1.010; 95% confidence interval [CI], 1.004–1.017; P=0.001) and multiple joint involvement (OR, 3.027; 95% CI, 1.831–5.004; P<0.001) were significantly associated with increased risk of formation of tophi. The presence of tophi was significantly associated with a rapid decline in the eGFR (β=-0.141; P=0.035).Conclusion:A prolonged symptom duration and multiple joint involvement were independent risk factors for tophi as the presenting symptom in gout patients. The presence of tophi was associated with a declining renal function. Therefore, an early diagnosis and active treatment are important in tophaceous gout.References:[1]Bardin T, Richette P.

Abstract Background Nitrofurantoin has been used to treat cystitis in women; however, data supporting its use in men is lacking. In addition, recent retrospective studies have challenged the manufacturer’s recommendation to avoid nitrofurantoin with creatinine clearances (CrCl) less than 60 mL/min. The purpose of this study is to compare the efficacy and safety of nitrofurantoin for the treatment of acute cystitis in male and female veterans with variable degrees of renal dysfunction. Methods A retrospective chart review was conducted in adult patients who received nitrofurantoin for acute cystitis in the outpatient setting between May 1, 2018 and May 1, 2019. The primary outcomes were rates of clinical cure as compared between males and females, and across various renal function groups (CrCl greater than 60 mL/min, 30 to 60 mL/min, and less than 30 mL/min) following treatment with nitrofurantoin. The secondary outcome was adverse event rates. Results A total of 446 patients were included with 278 females and 168 males. Overall clinical cure rate was 86.5% (n=386). Clinical cure rate did not vary between genders (p=0.0851) or CrCl ranges (p=1.0) as shown in the tables. Benign prostatic hyperplasia (BPH) was associated with decreased odds of clinical cure (OR 0.50 [95% CI 0.26-0.97], p=0.0404) in addition to cirrhosis (OR 0.22 [95% CI 0.06-0.91], p=0.0357). Adverse events occurred in 2% of patients and did not vary based on gender or renal function. RATES OF CLINICAL CURE Conclusion There was no statistically significant difference in clinical cure with nitrofurantoin between genders and various renal impairments. However, history of BPH and cirrhosis were associated with decreased efficacy. Subgroup analysis also revealed lower efficacy in males with CrCl greater than 60 mL/min versus females with similar renal function. This study adds to the growing body of literature suggesting that renal dysfunction with CrCl of 30 to 60 mL/min may not carry the risk of treatment failure and adverse effects previously associated with nitrofurantoin, but large randomized trials are needed to confirm these results.

Abstract Background Renal dysfunction may influence outcomes after pulmonary embolism (PE). We determined the incremental value of adding renal function impairment (estimated glomerular filtration rate, eGFR &lt;60 ml/min/1.73m2) on top of the 2019 ESC prognostic model, for the prediction of 30-day all-cause mortality in acute PE patients from a prospective, multicenter cohort. Methods and results We identified which of three eGFR formulae predicted death most accurately. Changes in global model fit, discrimination, calibration and net reclassification index (NRI) were evaluated with addition of eGFR. We prospectively included consecutive adult patients with acute PE diagnosed as per ESC guidelines. Among 1,943 patients, (mean age 67.3±17.1, 50.4% women), 107 (5.5% (95% CI 4.5–6.5%)) died during 30-day follow-up. The eGFRMDRD4 formula was the most accurate for prediction of death. The observed mortality rate was higher for intermediate-low risk (OR 1.8, 95% CI 1.1–3.4) and high-risk PE (OR 10.3, 95% CI 3.6–17.3), and 30-day bleeding was significantly higher (OR 2.1, 95% CI 1.3–3.5) in patients with vs without eGFRMDRD4 &lt;60 ml/min/1.73m2. The addition of eGFRMDRD4 information improved model fit, discriminatory capacity, and calibration of the ESC models. NRI was significantly improved (p&lt;0.001), with 18% reclassification of predicted mortality, specifically in intermediate and high-risk PE. External validation using data from the RIETE registry confirmed our findings (Table). Conclusion Addition of eGFRMDRD4-derived renal dysfunction on top of the ESC prognostic algorithm yields significant reclassification of risk of death in intermediate and high-risk PE. Impact on therapy remains to be determined. Funding Acknowledgement Type of funding source: Private grant(s) and/or Sponsorship. Main funding source(s): BMS-Pfizer Alliance, Bayer Healthcare

AbstractCardiovascular disease (CVD) is a major cause for a significant proportion of all deaths and disability worldwide. Postoperative renal dysfunction following cardiac surgery is not an uncommon complication of cardiac surgery, which has serious implications with regard to morbidity, mortality, financial expenditure, and resource utilization. This study was performed to compare outcomes of patients with preoperative renal dysfunction with those having normal renal function undergoing off-pump coronary artery bypass grafting (OPCABG). Patients were divided into two categories, depending on their preoperative serum creatinine and glomerular filtration rate (GFR). The preoperative renal dysfunction was defined as serum creatinine >1.3 mg/dL and/or estimated GFR (eGFR) of <60 mL/min/1.73 m2. The category A patients had normal renal function defined as serum creatinine ≤1.3 mg/dL and/or eGFR of ≥60 mL/min/1.73 m2 while the category B patients had preoperative renal dysfunction that did not necessitate renal dialysis. Blood samples were collected from both category patients for serum creatinine prior to surgery, following surgery, on postoperative days 1, 2, 3, 4, 5, and on the day of discharge. The occurrence of acute kidney injury (AKI) was defined as an increase in the serum creatinine levels of ≥0.3 mg/dL within 48 hours or an increase of ≥1.5 above baseline known or presumed to have occurred within the previous 7 days based on Kidney Disease Improving Global Outcomes criteria. This study demonstrated that there was worsening of renal function in 7.4% of patients with normal renal function and 10.74% of patients with renal dysfunction that was not statistically different. Based on the results, we conclude that preoperative renal dysfunction may be a contributing predictor of AKI following OPCABG, and we recommend that the patients with more severe renal dysfunction with eGFR of 45–60 mL/min should be studied to demonstrate this hypothesis.

We investigated whether the treatment with 17β-oestradiol has renal protective effects in male rats with ischaemic acute renal failure (ARF). We also examined if the effect of 17β-oestradiol is accompanied by suppression of enhanced endothelin-1 production in postischaemic kidneys. Ischaemic ARF was induced by clamping the left renal artery and vein for 45min followed by reperfusion, 2 weeks after contralateral nephrectomy. Renal function parameters such as blood urea nitrogen, plasma creatinine and creatinine clearance were measured to test the effectiveness of the steroid hormone. Renal function in ARF rats markedly decreased 24h after reperfusion. The ischaemia/reperfusion-induced renal dysfunction was dose-dependently improved by pretreatment with 17β-oestradiol (20 or 100µg/kg, intravenously). Histopathological examination of the kidney of untreated ARF rats revealed severe lesions, such as tubular necrosis, proteinaceous casts in tubuli and medullary congestion, all of which were markedly improved by the higher dose of 17β-oestradiol. In addition, endothelin-1 content in the kidney after the ischaemia/reperfusion increased significantly by approx. 2-fold over sham-operated rats, and this elevation was dose-dependently suppressed by the 17β-oestradiol treatment. These results suggest that oestrogen exhibits protective effects against renal dysfunction and tissue injury induced by ischaemia/reperfusion, possibly through the suppression of endothelin-1 overproduction in postischaemic kidneys.

Intraperitoneal injection of ferric nitrilotriacetate (Fe-NTA) to rats and mice results in iron-induced free radical injury and cancer in kidneys. This study was designed to investigate the effect of catechin, a bioflavonoid with antioxidant potential, on Fe-NTA-induced nephrotoxicity in rats. Four groups were employed in the present study. Group I served as control group, Group II animals received Fe-NTA (8 mg iron/kg body weight i.p.), Group III animals were given 40 mg/kg catechin p.o. twice a day for 4 days and on the 5th day Fe-NTA was challenged, and Group IV animals received catechin alone for 4 days. Renal function was assessed by measuring plasma creatinine and blood urea nitrogen. The oxidative stress was measured by renal malondialdehyde levels, reduced glutathione levels and by enzymatic activity of catalase, glutathione reductase and superoxide dismutase. One hour after a single intraperitoneal (i.p.) injection of Fe-NTA (8 mg iron/kg), a marked deterioration of renal architecture, renal function and severe oxidative stress was observed. Pretreatment of animals with catechin markedly attenuated renal dysfunction, reduced elevated thiobarbituric acid reacting substances (TBARS), restored the depleted renal antioxidant enzymes and normalized the renal morphological alterations. These results clearly demonstrate the role of oxidative stress and its relation to renal dysfunction, and suggest a protective effect of catechin on Fe-NTA-induced nephrotoxicity in rats.

Introduction. Renal dysfunction is one of complications in patients with obstructive icterus. It is important to recognize it early and take adequate measure to prevent its occurrence. One third of the patients with obstructive icterus have deterioration of renal function before surgical intervention. The aim of the research was to assess the renal dysfunction markers in patients with obstructive icterus. The following factors were examined: diuresis, urinary sodium concentration, sodium excretory fraction, urine osmolality, osmotic concentration index, creatinine concentration index and renal index of lesion. Material and methods. The study included 85 patients with obstructive icterus (50 patients before surgical intervention and 35 after surgical intervention) and 30 patients without icterus as a control group. The patients with normal renal function before the development of the disease were included. Results. Malignant etiology was present in 39 patients and benign in 46 patients of the examined group. The evaluation parameters of renal function were examined in all of the patients. Creatinine concentration index led to the greatest change in the coefficient value of an internal consistency, showing that it was the best renal function marker in the examined group of patients with icterus. The next one was the urinary osmolality, since its exclusion would lead to a decrease in the value of Cronbach ? coefficient to 0.06. Icterus and surgical intervention show statistically significant effects to change in the value of the markers of laboratory differentiation of renal function, observed as an entire set. Discussion and conclusion. The examination showed that the concentration clearances of creatinine and urine osmolality are the parameters which point to the probability of renal dysfunction occurrence in obstructive icterus.

Chronic kidney disease is common in geriatric cats, but most cases have nonspecific renal lesions, and few studies have correlated these lesions with clinicopathological markers of renal dysfunction. The aim of this study was to identify the lesions best correlated with renal function and likely mediators of disease progression in cats with chronic kidney disease. Cats were recruited through 2 first-opinion practices between 1992 and 2010. When postmortem examinations were authorized, renal tissues were preserved in formalin. Sections were evaluated by a pathologist masked to all clinicopathological data. They were scored semiquantitatively for the severity of glomerulosclerosis, interstitial inflammation, and fibrosis. Glomerular volume was measured using image analysis; the percentage of glomeruli that were obsolescent was recorded. Sections were assessed for hyperplastic arteriolosclerosis and tubular mineralization. Kidneys from 80 cats with plasma biochemical data from the last 2 months of life were included in the study. Multivariable linear regression ( P < .05) was used to assess the association of lesions with clinicopathological data obtained close to death. Interstitial fibrosis was the lesion best correlated with the severity of azotemia, hyperphosphatemia, and anemia. Proteinuria was associated with interstitial fibrosis and glomerular hypertrophy, whereas higher time-averaged systolic blood pressure was associated with glomerulosclerosis and hyperplastic arteriolosclerosis.

Background and Purpose: Chronic kidney disease (CKD) is known to have affected the systemic vasculature and its remodeling, which eventually led to the systemic arterial stiffness. However, the relationship between cerebral circulation and impaired renal function is poorly understood. To evaluate the effect of renal dysfunction to increase systemic and intracranial arterial stiffness, we assessed the relation between renal resistive index (RRI) and pulsatility index (PI) of the middle cerebral artery (MCA). Methods: We included patients with acute lacunar infarction. Demographic and clinical data were collected by retrospective chart review. Bilateral transcranial Doppler ultrasound (TCD) examination of the MCAs was performed using the ST3 Ultrasound system (Spencer Technologies) and PI were calculated. RRI was obtained through kidney Doppler sonography. Subjects with occlusion or significant stenosis of MCA, atrial fibrillation, bilaterally absent transtemporal sonographic windows were excluded. Results: Of the 283 included subjects (mean age 67.8 ± 10.2), 74 patients had renal dysfunction (glomerular filtration rate < 60ml/min/1.73m2 at admission) and 49 patients underwent kidney Doppler ultrasound within 1 year since their acute stroke. Renal dysfunction was significantly associated with higher arterial stiffness (median PI 1.12, IQR 0.85 to 1.57 vs. controls PI 0.84, IQR 0.54 to 1.22 [p<0.0001]). There was a proportional relationship between the degree of renal dysfunction and the distal vascular resistance. In multivariate adjusted regression analysis, renal function was related to high PI (p<0.001). Furthermore, there is strong correlation between RRI and PI ( r =0.65, p <0.001). Conclusions: In patients with lacunar infarction, renal impairment is an independent determinant of increased arterial stiffness in cerebral circulations. In addition, PI is significantly associated with RRI.
