Clinical and bacteriological outcome of different doses and duration of pivmecillinam compared with placebo therapy of uncomplicated lower urinary tract infection in women: the LUTIW project.
OBJECTIVE
To analyse associations between symptoms and bacteriuria in uncomplicated lower urinary tract infection in women (LUTIW) and to evaluate outcome of therapy with three different regimens of pivmecillinam or placebo.


METHODS
Prospective, multicentre, randomized, double-blind, and placebo-controlled therapy study. Symptoms registered at inclusion, during therapy and at follow-up visits after 8-10 and 35-49 days. Significant bacteriuria defined according to current European guidelines.


METHODS
A total of 18 primary healthcare centres in northern Sweden. Subjects. Women aged 18 years and above with symptoms of urgency, dysuria, supra pubic or loin pain. Main outcome measures. Symptoms and bacteriuria at inclusion and course of symptoms, bacteriuria, and their combinations during and post-therapy.


RESULTS
At inclusion, no associations or significant differences were found between symptom scores and bacteriuria, bacterial counts, or species. The 884 patients (77%) with significant bacteriuria were followed up. All pivmecillinam therapies were superior to placebo (p < 0.001). From day six until first follow-up, the mean values of all symptoms were higher and the bacteriological cure was lower at first follow-up in the three days (84%) compared with the seven days regimens (93-94%, p < 0.001). At final follow-up clinical cure was similar in all pivmecillinam regimens (65-72%) as was bacteriological cure (83-89%). Pivmecillinam had few low to mild adverse reactions, comparable to placebo.


CONCLUSIONS
Symptoms are not conclusive for diagnosis of LUTIW. Pivmecillinam therapies are superior to placebo and seven days regimens are more efficient than three days. Pivmecillinam 200 mg x 2 x 7 days is recommended as a first-line therapy for LUTIW.
