Protein intake renal failure

He was provided with a diet restricted in protein but was found to limit his own protein intake to 1.0 to 1.2 g/kg. Treatment with large doses of vitamin B12 for a period of 4 months made no difference to the concentration of methylmalonic acid excreted in his urine. He required frequent hospitalization for anorexia, vomiting, and dehydration. At 18 months of age he developed renal failure, and at 3 years he became oliguric. His physical development appeared normal for the first 12 months and then it deteriorated. He started to walk at 31 years, but at this time he also had hepatomegaly and persistent vomiting. On the basis of a developmental screening test he was found to be 12 to 18 months behind in all areas tested.

Mechanism of Action. The drug is usually absorbed by the oral route upto 90-100%. However, its absorption is predominantly diminished to a small extent milk and food intake and appreciably by the presence of iron preparations and nonsystemic antacids . It is protein-bound in plasma between a range of 70-75%. The volume of distribution v/ stands at 0.14 - 0.7 mL. The plasma half-life ranges between 11-17 hours. It gets excreted unchanged in urine upto 10% however, its biological half-life is usually prolonged chiefly in the incidence of renal failure. 

Chronic renal failure patients on hemodialysis and peritoneal dialysis are at risk for thiamine deficiency due to inadequate nutrition in part and possible thiamine loss during the dialysis process. Renal failure patients are often on a diet restricted in protein and potassium, which increases the risk of thiamine deficiency (Masud, 2002 Piccoli et al, 2006). Studies with detailed dietary surveys have shown poor oral intake of thiamine in chronic renal failure patients (Hung et al., 2001). There is no convincing evidence that thiamine levels are significantly altered by either hemodialysis or peritoneal dialysis (Reuler et al, 1985). DeBari et al (1984) measured thiamine levels of granulocytes, erythrocytes and plasma. They found no significant differences in thiamine levels in dialysis patients compared to controls. Further research in this area would benefit chronic renal failure patients and help determine possible need for supplementation of water-soluble vitamins. 

The kidney plays a key roll in the absorption of mercury in the body. Kidney tissue contains a thiol-rich protein called metaUothionein. Exposure of the kidney to mercury and other toxic metals causes production of this protein which binds the metals tightly, and retains it in the kidney in a relatively harmless form. As long as the kidney is not overwhelmed by the influx of the toxic metal, the excretion of mercury will eventually balance intake so that worsening of adverse symptoms will be limited. However, acute levels can lead to renal failure. 

Urea is the most important end product of protein degradation in the body. Its concentration in blood depends on the protein catabolism and nutritive protein intake and is regulated by renal excretion. Thus the estimation of blood urea nitrogen is important in the assessment of kidney failure. The normal level of urea ranges from 3.6 mM to 8.9 mM. All enzymatic methods for urea determination are based on the principle of urea hydrolysis by urease ... 

Increases in free and protein-conjugated acrolein have also been detected in various renal pathologies, including renal failure, and the metabolism of alcohol in the liver has been shown to induce spermine oxidation resulting in increased detection of acrolein (Sakata et al. 2003a, b Uemura et al. 2013). This increase in hepatocellular SMOX suggests a mechanism for the liver toxicity and decreased regenerative abilities associated with chronic alcohol intake.
