title: [Drug-induced acute kidney injury].
abstract: Due to their physiological function, the kidneys are exposed to high concentrations of numerous drugs and their metabolites, making them vulnerable to drug-related injuries. This article provides an overview of the pathophysiological mechanisms involved in nephrotoxicity, the most common nephrotoxic drugs, and the risk factors for the occurrence of drug-induced acute kidney injuries. NSAIDs, diuretics, ACE inhibitors, and angiotensin II receptor blockers (ARBs} are the most frequent prerenal causes of an acute elevation in creatinine levels. Primary vascular damage arises from thrombotic microangiopathy (e. g. due to cic/osporin, tacrolimus, muromonab-CD3, mitomycin C, quinine, ticlopidine, clopidogrel}. Anticoagulants and thrombolytic medications lead to secondary blood vessel damage by cholesterol emboli, embolism of thrombus material into the periphery or bleeding. Tubulopathies can be observed on treatment with ifosfamide and cisplatin (rarely with cyclophosphamide or carboplatin), aminoglycosides, vancomycin, and radiocontrast agents. Immunological mechanisms underlie interstitial nephritides, which are induced by drugs in about 85% of cases. In drug-induced glomerulopathies;- renal biopsy allows closer identification of the triggering medication. Drug-induced systemic lupus erythematosus (SLE} represents a special form of immune complex glomerulonephritis and can be triggered by procainamide, hydralazine, isoniazid, methyldopa, quinidine, chlorpromazine, and propylthiouracil. Crystal-induced kidney injury is caused by precipitation of drugs (e. g. aciclovir, sulfonamide antibiotics, methotrexate, indinavir) in the renal tubules and the urine-conducting organs with consecutive obstruction thereof.
