[Clinico-therapeutic and microbiologic studies of the Bulgarian antibiotic cephalothin in patients with active pyelonephritis].

: A total of 38 patients with active pyelonephritis and significant bacteriuria were treated with the Bulgarian antibiotic cephalotin, the bacteria isolated from their urine manifesting susceptibility to the Bulgarian broad-spectrum antibiotic cephalotin. Twenty six from the patients were with preserved renal function, and 12 with various stages of renal insufficiency. The subjective complaints, febrility, leukocyturia and bacteriuria were best affected. The highest anti-bacterial effect was observed in the patients with uroinfections caused by E. coli, Proteus mirabilis, Klebsiella and staphylococci. Cephalotin has a good tolerance and has no adverse effects. Painful infiltrations were established in some of the patients in the region of the site of intramuscular application, with a transitory character. Cephalotin was assessed, on the base of the study, to be a good and prospective broad-scpectrum antibiotic, deserving to be widely applied in the therapeutic practice.
