Current evidence shows that aminoglycosides do retain activity against the majority of Gram-negative clinical bacterial isolates in many parts of the world. Still, the relatively frequent occurrence of nephrotoxicity and ototoxicity during aminoglycoside treatment makes physicians reluctant to use these compounds in everyday practice.
Nephrotoxicity is toxicity in the kidneys. It is a poisonous effect of some substances , both toxic chemicals and medications , on kidney function . [ 1 ] There are various forms, [ 2 ] and some drugs may affect kidney function in more than one way.
Combined with an aminoglycoside, it can increase the possibility of ototoxicity, nephrotoxicity and neuromuscular blockage, result in some hearing loss or can continue to deafness. It could be a temporary symptom, but often be permanent. Neuromuscular blockade can lead to skeletal muscle weakness and respiratory depression or paralysis (apnea).
The nephro- and ototoxicity are thought to be due to aminoglycosides' tendency to accumulate in the kidneys and inner ear. [8] Diagram of the inner ear. Amikacin causes damage to the cochlea and vestibules. Amikacin can cause neurotoxicity if used at a higher dose or for longer than recommended.
Aminoglycoside-3'-phosphotransferase (APH(3')), also known as aminoglycoside kinase, is an enzyme that primarily catalyzes the addition of phosphate from ATP to the 3'-hydroxyl group of a 4,6-disubstituted aminoglycoside, such as kanamycin. [2]
Gentamicin should not be used if a person has a history of hypersensitivity, such as anaphylaxis, or other serious toxic reaction to gentamicin or any other aminoglycosides. [15] Greater care is required in people with myasthenia gravis and other neuromuscular disorders as there is a risk of worsening weakness. [ 5 ]
It has been suggested that an alteration of DNA function is possibly responsible for the post-antibiotic effect following the observation that most inhibitors of protein and nucleic acid synthesis (aminoglycosides, fluoroquinolones, tetracyclines, clindamycin, certain newer macrolides/ketolides, and rifampicin and rifabutin) induce long-term ...
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
