Antibacterial effect of NSAIDS on clinical isolates of urinary tract infection and diabetic foot infection.
Non Steroidal Anti-inflammatory Drugs (NSAIDS) are a group of chemically dissimilar agents that have primary effect of inhibition of prostaglandin's synthesis. Aspirin (Acetyl Salicylic Acid) is used as an analgesic, anti pyretic, anti-inflammatory agent and also have an anticoagulant effect. Tylenol (acetaminophen) is used as pain reliever. The objective of this study was to determine the effect of Aspirin and Tylenol against clinical isolates of urinary tract infection (UTI) and diabetic foot infections. A total of 100 clinical isolates were analyzed. Out of these 50 were urine samples from diabetic patients with UTI and 50 pus samples from diabetic foot infection. Bacteriological study was done by inoculating urine samples on Cysteine Lactose Electrolyte deficient (CLED) media. Pus samples were inoculated on Blood agar and MacConkey's agar. Identification was done by colony characteristics, gram staining and standard biochemical tests and Quick Test Strip (QTS-20) DESTO Laboratories, Karachi. Antibacterial effect of Aspirin and Tylenol were tested against 100 clinical isolates by Replica plate method, Agar well diffusion method and tube dilution method. Concentrations of Aspirin and Tylenol (10 microg, 50 microg, 100 microg, 500 microg, 1000 microg) were made in Muller Hinton media. Bacteria isolated from urine samples were Escherichia coli 30%, Staphylococcus aureus 20%, Enterococcus faecalis 10%, S. saprophyticus 10%, Proteus spp. 6%, Pseudomonas spp. 6%, S. pyogenes 6%, S. agalactiae 6%, S. epidermidis 4%, and Klebsiella spp. 2%. Bacteria isolated from pus samples were S. aureus 30%, Pseudomonas aeruginosa 18%, S. epidermidis 14%, Klebsiella pneumonia 12%, Proteus mirabilis 12%, E. coli 10%, P. vulgaris 4%. Aspirin was effective at 100-500 microg concentration against all isolates. Tylenol has marked effect on pathogens at 100 microg concentration. Aspirin and Tylenol along with analgesic, anti-pyretic, anti-inflammatory properties also have marked anti bacterial effect on isolates from UTI and Diabetic foot infections and inhibits the growth of both gram negative and gram positive bacteria, and both can be used synergistically with antibiotics for effective treatment.
