Abstract:
BACKGROUND Diabetes mellitus (DM) is a risk factor for renal failure and possibly for renal cell carcinoma (RCC). Post-transplantation DM occurs frequently after solid organ transplantation. We investigated whether new-onset diabetes after renal transplantation (NODAT) is a risk factor for RCC or renal failure. MATERIAL AND METHODS Data of 96,699 discharged patients with and without NODAT were extracted from the 2005-2014 Nationwide Inpatient Sample (NIS) database, after excluding patients with DM diagnosed at least 1 year prior to renal transplantation. Main outcomes were RCC diagnosis less than 1-year post-transplantation, RCC stage, and renal failure. Univariate and multivariate regression analyses were performed to identify demographic and clinical factors associated with post-transplantation RCC or renal failure. RESULTS Significant differences were found in age and race between patients with and without NODAT (both P<0.001). The renal failure rate was 0.8% (n=1) in NODAT patients and 0.3% (n=314) in those without NODAT. Older age (OR, 1.030; 95% CI: 1.023 to 1.036), male (OR, 1.872; 95% CI: 1.409 to 2.486), Black (OR, 2.199; 95% CI: 1.574 to 3.071) and hospitalization in urban teaching hospitals were associated with increased risk of RCC. CONCLUSIONS Analysis of over 90,000 NIS hospitalizations with diagnosis-coded kidney transplantation suggested that NODAT may not be an independent risk factor for RCC and renal failure.

01:17Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
01:11Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
01:23Renal Clearance
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

One important factor is the relationship between renal clearance and the apparent volume of distribution. Renal clearance tends to be inversely proportional to the apparent volume of distribution. Drugs with an extensive distribution volume or those...
