Aluminum toxicity is a documented cause of encephalopathy, anemia, and osteomalacia. Excretion is primarily renal; therefore, patients with renal insufficiency are at risk for aluminum accumulation and toxicity. This has been demonstrated in uremic children treated with aluminum-containing antacids. The purpose of this study was to determine whether plasma aluminum levels were elevated in infants with normal renal function during prolonged aluminum-containing antacid use. Ten study infants (mean age = 5.8 months), who had been receiving antacids for at least 1 week, were compared with 16 control infants (mean age = 9.8 months) not receiving antacids. The study patients consumed 123 ± 16 mg/kg per day (mean ± SEM) of elemental aluminum for an average of 4.7 weeks. Their plasma aluminum level (37.2 ± 7.13 µg/L) was significantly greater than that of the control group (4.13 ± 0.66 µg/L) (P < .005). It is concluded that plasma aluminum levels may become elevated in infants with normal renal function who are consuming high doses of aluminum-containing antacids. The safety of antacids containing aluminum should not be assumed and they should be used judiciously in infants, with careful monitoring of the aluminum dose and plasma level.

The purpose of this study was to evaluate periodontal disease (PD) in dogs with chronic renal failure (CRF) and to compare it to PD in dogs with normal renal function (NRF). Twelve dogs with CRF and 24 dogs with NRF, all presenting dental pocket formation, were compared. In all dogs, serum creatinine, blood urea nitrogen, urine specific gravity and total red and white blood cells were determined. A complete oral examination was also performed including evaluation of bacterial plaque, gingivitis, gingival recession, pocket, calculus, dental mobility, dental loss, and ulcers. These data were used to calculate plaque index (PI), gingival index (GI) and periodontal destruction index (PDI). PD was graded as mild, moderate or severe based on the results. Mild, moderate or severe PD was observed in dogs with NRF, whereas dogs with CRF presented either mild or severe PD. Dogs with NRF showed higher involvement of the maxillary teeth, whereas dogs with CRF showed a higher involvement of the mandibular teeth. Plaque index was significantly higher in dogs with NRF. It was concluded that lesion distribution and periodontal disease progression may be altered in dogs with CRF, and gingival inflammatory response differs in dogs with NRF and CRF regarding to the stage of periodontal disease.

AbstractAssociations between hepatitis C virus (HCV) and chronic kidney disease (CKD) have been reported; however, differences of renal progression between general and CKD population remain to be elucidated in prospective studies. A total of 1179 participants, who have tested for anti-HCV antibody, were enrolled and prospectively followed for 3 years. The risks associated with HCV infection, in terms of incidence of CKD, annual estimated glomerular filtration rate (eGFR) changes and 50% decline of eGFR at 3-year from baseline, were compared between normal renal function subjects and CKD patients. Overall, 111 of 233 (47.6%) CKD patients and 167 of 946 (17.7%) non-CKD subjects had HCV infection. The crude incidence rates of CKD were 226.9 per 1000 person-years and 14.8 per 1000 person-years in in HCV and non-HCV infected patients, respectively. The adjusted hazard ratio of HCV infection for incident CKD was 7.9 (95% CI 5–12.7). The HCV-infected normal renal function subjects were independently associated with increased risks of eGFR decline in the 1-year, 2-year and 3-year, respectively. The risk associations remained significant in 50% decline of eGFR at 3 years models and in different subgroup analyses. The increases of risks of eGFR decline were also notorious among overall HCV-infected CKD patients. However, the risk associations were less prominent in subgroup analyses (elderly, women and diabetic patients). The findings highlighted the importance of viral diagnosis with not only prognostic but also public health implications for preserving kidney function.

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.

Urinary Citrate

Abstract Background and Aims In polycystic kidney disease (PKD) it is frequently found a reduction in urinary citrate that is related with degree of renal impairment but it is unknown if this alteration is specific or if it is also present in other nephropathies. Recently it has been suggested that urinary citrate could be a marker of covert metabolic acidosis and reflects acid retention in chronic kidney disease (CKD). Our aim was to compare urinary citrate in PKD with other renal diseases and to show its relation with serum bicarbonate and excretion of uric acid and calcium. Method We determined citrate, calcium and uric acid in 24-hour urine in patients with PKD and with other nephropathies with varied degree of renal impairment followed in a outpatient clinic of nephrology. Results We included 291 patients, 119 with glomerular diseases, 116 with PKD, 21 with other nephropathies, and 35 patients with normal renal function. Urinary citrate was higher in women (Females 309±251 mg/gCr vs. males 181±145 mg/gCr, p&lt;0.001) and in patients with normal renal function (normal 380±210 mg/gCr; PKD 203±166 mg/gCr; glomerular 279±282 mg/gCr; p&lt;0,001). PKD patients showed similar values of urinary citrate to patients with glomerular diseases and with other nephropathies. We observed a progressive reduction in urinary citrate parallel to degree of renal impairment, in a comparable way among patients with PKD and glomerular diseases. We did not observe a relationship between urinary citrate and serum bicarbonate levels. Calcium and uric acid elimination in ADPKD patients was similar to other nephropathies and lower to patients with normal renal function. However, serum uric acid was significantly higher in glomerular patients than other nephropathies after adjust with glomerular filtration rate and sex. Conclusion Hypocitraturia is not specific of PKD but it is also present in all nephropathies. Urinary citrate are related to degree of renal impairment and it is not related with serum bicarbonate. We think that it could be interesting to study urinary citrate as a marker of renal function and its role as prognostic factor of renal deterioration.
