Clinical studies on recurrence of acute uncomplicated cystitis

: Recurrence rate and symptoms after chemotherapy against acute uncomplicated cystitis (AUC) were studied. Upon completion of a 7-day treatment with two regimens, one of CEX alone (Group C) and the other of a combination of CEX with Lysozyme (Neuzym) (Group L), at a dose of 1 g CEX daily, efficacy of the drugs was assessed according to the criteria established by the UTI Study Group. The forty one cases in Group C and 38 cases in Group L showing an excellent response were evaluated for recurrence. The rates of recurrence were 12.2% in Group C and 21.1% in Group L during the first 7 days after treatment. In recurrent cases, bacteriuria was seen in 84.6% (11/13), pyuria in 53.8% (7/13) and miction pain in 30.8% (4/13). Thus, bacteriuria and pyuria should be the items of the criteria for AUC recurrence.
