What is drug-induced renal failure?
Drug-induced nephrotoxicity is increasingly recognized as a significant contributor to kidney disease including acute kidney injury (AKI) and chronic kidney disease (CKD). Nephrotoxicity has a wide spectrum, reflecting damage to different nephron segments based upon individual drug mechanisms.
What drugs cause ATN?
Nephrotoxic medications that can lead to acute tubular necrosis should be avoided, including NSAIDs, antibiotics such as amphotericin B, aminoglycosides, vancomycin, piperacillin/tazobactam, and radiocontrast agents.
What are the most common Nephrotoxins?
4 Aminoglycosides are well recognized nephrotoxins, causing a dose-dependent reduction in approximately 50% of kidney function in 10%-20% of patients. Gentamicin is recognized as the most nephrotoxic commonly used agent among this group, followed by Tobramycin and Amikacin. …
What is the most common cause of post renal failure?
Postrenal causes typically result from obstruction of urinary flow, and prostatic hypertrophy is the most common cause of obstruction in older men. Prompt diagnosis followed by early relief of obstruction is associated with improvement in renal function in most patients.
Can drug-induced kidney damage be reversed?
Drug-induced renal impairment is generally reversible, provided the nephrotoxicity is recognized early and the offending medication is discontinued.
What is post renal AKI?
Postrenal acute kidney injury , which used to be called acute renal failure, occurs when an obstruction in the urinary tract below the kidneys causes waste to build up in the kidneys . It is not as common as intrinsic acute kidney injury (AKI) or acute tubular necrosis (ATN).
What causes drug induced kidney injury?
Aminoglycoside antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), contrast agents, and angiotensin converting enzyme inhibitors (ACEIs) are the most common cause of AKI in hospitalized patients (2). The risk of contrast-induced nephropathy is highest in diabetics and chronic kidney disease diabetes (9).
What is difference between AKI and ATN?
Acute tubular necrosis (ATN) is the most common cause of acute kidney injury (AKI) in the renal category (that is, AKI in which the pathology lies within the kidney itself). The term ATN is actually a misnomer, as there is minimal cell necrosis and the damage is not limited to tubules.
Can drug induced kidney damage be reversed?
Can kidney PPI be reversed?
Over five years of follow up, the researchers found that more than 80 percent of PPI users did not develop acute kidney problems, which often are reversible and are characterized by too little urine leaving the body, fatigue and swelling in the legs and ankles.
What are the 3 types of acute renal failure?
AKI occurs in three types—prerenal, intrinsic, and postrenal.
What causes post renal Aki?
Causes of acute kidney injury. Post-renal AKI occurs after acute obstruction of the urinary flow, which increases intra-tubular pressure and thus decreases GFR. In addition, acute urinary tract obstruction can lead to impaired renal blood flow and inflammatory processes that also contribute to diminished GFR.
How to treat drug induced acute renal failure?
Drug-Induced Acute Renal Failure. A mild decrease in renal function due to ACE inhibitors is acceptable due to the benefits that result from long-term therapy. Treatment should be started at low dosages, especially in patients with underlying risk factors, and the dose should be titrated gradually.
What is the impact of drug induced kidney injury?
Drug induced kidney injury is a frequent adverse event which contributes to morbidity and increased healthcare utilization. Our current knowledge of drug induced kidney disease is limited due to varying definitions of kidney injury, incomplete assessment of concurrent risk factors and lack of long term outcome reporting.
Can a drug induced nephrotoxicity be reversible?
Monitor renal function and vital signs after starting or increasing the dose of drugs associated with nephrotoxicity, especially when used chronically. Drug-induced renal impairment is generally reversible, provided the nephrotoxicity is recognized early and the offending medication is discontinued.
Are there any new medications for renal failure?
Direct renal tubular toxicity has also been described with a number of new medications with unique effects on the epithelial cells of the kidney. These include the antiviral agents cidofovir, adefovir, and tenofovir as well as the bisphosphonate pamidronate.
