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.
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.
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).
Gentamicin is a type of aminoglycoside [5] and works by disrupting the ability of the bacteria to make proteins, which typically kills the bacteria. [ 5 ] Gentamicin is naturally produced by the bacterium Micromonospora purpurea , [ 9 ] [ 5 ] was patented in 1962, approved for medical use in 1964. [ 10 ]
Serious side effects include ringing in the ears or loss of hearing, toxicity to kidneys, and allergic reactions to the drug. [11] Ototoxicity is a common quality among aminoglycosides, and its rate of incidence in kanamycin is around 3-10%.
NAD helps hundreds of enzymes in the cell do their jobs. "Some of those enzymes are involved in cellular repair, so helping cells that have damage due to UV radiation, for example," says Martens.
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]
