• Drugs with predominantly renal clearance will most likely require dose adjustment for RRT • Drugs with high Vd are poorly cleared by RRT • Drug with high protein binding are poorly cleared by RRT •Unbound fraction is active and cleared •Patients in ICU often have low albumin • CRRT is less effective than normal kidneys at clearing drugs • Molecular weight matters depending on
Renal clearance (Cl R ) was measured and non‐renal clearance (Cl NR ) was calculated as the difference between total clearance and Cl R . Differences in cumulative amount in urine, Cl R , and Cl NR between study weeks 1 and 16 and relationships between proteinuria (protein:creatinine ratio (Up/c)), and Cl R and Cl NR were evaluated. Up to 13% of the adalimumab dose was lost in urine. Cl NR
Cystatin C has been proposed as an endogenous marker for measuring glomerular filtration rate (GFR) and is regarded as being equivalent to or better than creatinine. However, there are no published data on the production rate (Cyspr) or on the non‐renal clearance of cystatin C (CLnr) in humans, which are essential parameters for GFR calculation.
Renal clearance proportional to c hange in filtration clearance Non-renal clearance is unchanged in renal impairment, has a significant effect on total clearance . Giusti-Hayton Method Assumes no change in non- renal clearance, V, f e or f u Change in renal clearance is estimated from ratio of creatinine clearance in impa ired kidney function verses normal creatinine clearance (~100mL/min) D
The overall mean non‐renal clearance was 18 per cent (ranging from 9 to 25 per cent) of its plasma clearance. The mean iothalamate/inulin renal clearance ratio was about 0·84 with individual values ranging from 0·72 to 0·95. The significant (4–26 per cent) plasma protein binding of iothalamate in these dogs was the main reason for the lower‐than‐unity clearance ratios obtained. The

Renal function loss in non-renal as compared to renal transplant recipients Chronic renal function loss occurs in many patients after initially successful renal transplantation. Multiple risk factors, both related and unrelated to the allograft status of the grafted kidney, have been identified, suggesting a complex and multifactorial pathogenesis [ 1 ].

Non-renal indications for continuous renal replacement therapy. While there is clear support for the use of continuous renal replacement therapy (CRRT) in critically ill acute renal failure patients, there are other illnesses without renal involvement where CRRT might be of value.

Molecular genetic analysis of familial and non-familial cases of conventional renal cell carcinoma (RCC) revealed a critical role(s) for multiple genes on human chromosome 3. For some of these genes, e.g. VHL , such a role has been firmly established, whereas for others, definite confirmation is still pending.
Non-renal clearance (Cl NR) in AKI differs from that observed in patients without renal impairment. Even drugs normally associated with predominantly renal clearance (e.g., vancomycin) appear to be impacted upon by change in Cl NR in AKI [ 10 ] although the mechanisms are unclear.

The Kidney Each kidney is composed of three sections: The outer (renal) cortex, the (renal) medulla (middle part) and the hollow inner (renal) pelvis. The cortex is where the blood is filtered. The medulla contains the collecting ducts which carry filtrate (filtered substances) to the pelvis. The pelvis is a hollow cavity where urine accumulates and drains into the ureter.

These results show that for subcutaneous administration of low-dose IL-2, renal clearance of IL-2 is not important. This contrasts with high-dose, intravenous IL-2 where blood concentrations are higher and renal clearance seems to occur, perhaps because of saturation of the non-renal mechanisms of clearance. The subcutaneous route is certainly preferred if IL-2 is used in anephric patients and

Renal impairment reduces the clearance of some drugs. 4 When prescribing for patients on dialysis, it is essential to consult a reference guide to determine if the drug is subject to renal clearance and requires a dose adjustment. Given the paucity of large pharmacokinetic studies, dosing recommendations often differ and it may be difficult to favour one source over another. If no ‘dialysis
