Creatinine, a breakdown product of muscle creatine, is present in relatively stable levels in serum. It is filtered by the glomeruli and not reabsorbed by the tubules. Changes in renal function are reflected in levels of serum urea and creatinine. It is not uncommon for elderly patients, and those with heavy metal toxicity to have mild to moderate impairment of renal function. Renal disease is asymptomatic in most cases until late in its clinical course. Safe chelation therapy is highly dependent upon the adequacy of renal function. Excessive mobilization of toxic metals to poorly functioning kidneys may result in renal complications. It is advised that creatinine clearance be monitored prior to and throughout chelation therapy. Interpretive guidelines: 100 mL/min or higher usually indicates normal renal function. 50 mL/min or below is indicative of impaired kidney function. 30 mL/min or below is indicative of symptomatic renal failure. Exercise may cause increased clearance. Inaccurate results may be caused by failure to accurately follow the specimen collection instructions. The calculation for corrected creatinine clearance in mL/min: = Urine volume per minute x urine creatinine ÷ Serum creatinine x 1.73/body surface area References: 1.

Renal Effects of the Serine Protease Inhibitor Aprotinin in Healthy Conscious Mice
www.nature.com/aps ARTICLE OPEN Renal effects of the serine protease inhibitor aprotinin in healthy conscious mice Stefan Wörner1, Bernhard N. Bohnert1,2,3, Matthias Wörn1, Mengyun Xiao1, Andrea Janessa1, Andreas L. Birkenfeld1,2,3, Kerstin Amann4, Christoph Daniel4 and Ferruh Artunc 1,2,3 Treatment with aprotinin, a broad-spectrum serine protease inhibitor with a molecular weight of 6512 Da, was associated with acute kidney injury, which was one of the reasons for withdrawal from the market in 2007. Inhibition of renal serine proteases regulating the epithelial sodium channel ENaC could be a possible mechanism. Herein, we studied the effect of aprotinin in wild- type 129S1/SvImJ mice on sodium handling, tubular function, and integrity under a control and low-salt diet. Mice were studied in metabolic cages, and aprotinin was delivered by subcutaneously implanted sustained release pellets (2 mg/day over 10 days). Mean urinary aprotinin concentration ranged between 642 ± 135 (day 2) and 127 ± 16 (day 8) µg/mL . Aprotinin caused impaired sodium preservation under a low-salt diet while stimulating excessive hyperaldosteronism and unexpectedly, proteolytic activation of ENaC. Aprotinin inhibited proximal tubular function leading to glucosuria and proteinuria. Plasma urea and cystatin C concentration increased signiﬁcantly under aprotinin treatment. Kidney tissues from aprotinin-treated mice showed accumulation of intracellular aprotinin and expression of the kidney injury molecule 1 (KIM-1). In electron microscopy, electron-dense deposits were observed. There was no evidence for kidney injury in mice treated with a lower aprotinin dose (0.5 mg/day). In conclusion, high doses of aprotinin exert nephrotoxic effects by accumulation in the tubular system of healthy mice, leading to inhibition of proximal tubular 1234567890();,: function and counterregulatory stimulation of ENaC-mediated sodium transport.

Understanding Your Lab Results: Comprehensive Metabolic Screening Panel
Understanding Your Lab Results: Comprehensive Metabolic Screening Panel CHOLESTEROL and TRIGLYCERIDES are fats necessary for normal cell function. However, elevated levels of these fats have been associated with an increased risk of developing coronary disease, arteriosclerosis, and heart attack. A patient’s dietary status, medications, presence of illness, lifestyle, and family history may represent factors influencing cholesterol levels. The signifi- cance of cholesterol levels should be determined within the context of each individual patient. If your cholesterol level is 200 mg/dl or greater, please consult your physician. Triglyceride levels greater than 150 mg/dl, in a true fasting specimen, are considered elevated. In this case, please consult your physician. HDL (High-Density Lipoprotein) CHOLESTEROL, commonly known as the “GOOD” cholesterol, picks up cholesterol and transports it for removal from the body. The higher the HDL value, the lower the risk of developing coronary disease, arterioscle- rosis, and heart attack. LDL (Low-Density Lipoprotein) CHOLESTEROL, commonly known as the “BAD” cholesterol, picks up cholesterol and transports it to the cells of the body for storage. Desirable LDL levels are less than 130 mg/dl. The higher the LDL value, the greater the risk of developing coronary disease, arteriosclerosis, and heart attack. CHOLESTEROL/HDL RATIO is a calculation used to predict an increased or decreased risk of cardiovascular disease relative to a normal. The higher the ratio, the greater the risk of developing coronary disease, arteriosclerosis, and heart attack. GLUCOSE, commonly called a blood sugar, is the transport form of carbohydrates in the body as they move to storage or to utiliza- tion.

Decreased Counts - Leukocytopenia and neutropenia can result from nutritional deficiency, autoimmune disease, bone marrow infiltration (i.e., leukemia or myelodysplastic syndrome), radiation, and myelosuppression due to medications (including many cancer drugs). o Many treatment protocols require dose adjustments or the addition of colony stimulating factors (e.g., filgrastim) if ANC drops below 1.5 x 109/L.

Is There a Role for Ketoacid Supplements in the Management of CKD? Anuja P
Perspective Is There a Role for Ketoacid Supplements in the Management of CKD? Anuja P. Shah, MD,1 Kamyar Kalantar-Zadeh, MD, PhD,2 and Joel D. Kopple, MD1,3 Ketoacid (KA) analogues of essential amino acids (EAAs) provide several potential advantages for people with advanced chronic kidney disease (CKD). Because KAs lack the amino group bound to the a carbon of an amino acid, they can be converted to their respective amino acids without providing additional nitrogen. It has been well established that a diet with 0.3 to 0.4 g of protein per kilogram per day that is supplemented with KAs and EAAs reduces the generation of potentially toxic metabolic products, as well as the burden of potassium, phosphorus, and possibly sodium, while still providing calcium. These KA/EAA-supplemented very-low-protein diets (VLPDs) can maintain good nutrition, but the appropriate dose of the KA/EAA supplement has not been established. Thus, a KA/EAA dose-response study for good nutrition clearly is needed. Similarly, the composition of the KA/EAA supplement needs to be reexamined; for example, some KA/EAA preparations contain neither the EAA phenylalanine nor its analogue. Indications concerning when to inaugurate a KA/EAA- supplemented VLPD therapy also are unclear. Evidence strongly suggests that these diets can delay the need for maintenance dialysis therapy, but whether they slow the loss of glomerular ﬁltration rate in patients with CKD is less clear, particularly in this era of more vigorous blood pressure control and use of angiotensin/ aldosterone blockade. Some clinicians prescribe KA/EAA supplements for patients with CKD or treated with maintenance dialysis, but with diets that have much higher protein levels than the VLPDs in which these supplements have been studied.
