Disturbance of the Intestinal Microbiota by Temocillin vs Cefotaxime in Treatment of Febrile Urinary Tract Infections
Disturbance of the Intestinal Microbiota by Temocillin vs Cefotaxime in Treatment of Febrile Urinary Tract Infections
This study will evaluate the ecological impact on the intestinal microbiota and compare the
 safety and efficacy of temocillin compared to cefotaxime, in empiric treatment of febrile
 UTI. Half of participants will receive temocillin and the other half will receive cefotaxime.
Temocillin is a narrow spectrum antibiotic with activity against gram negative bacteria
 inclusive many ESBL producing bacteria. Temocillin is approved and marketed in a few European
 countries since the 1980´s but not in Sweden.

 The aim of the study is to find an ecological favorable alternative to cephalosporins in the
 treatment of this common indication.

 The hypothesis is that treatment with temocillin causes less disturbances on the intestinal
 microbiota while at least comparable efficacy.

 The study will be performed as an open prospective multicentre study with two parallel groups
 comparing 2 g temocillin three times daily with 1-2 g cefotaxim three times daily for 7-10
 days in male and female adult patients with febrile urinary tract infection.
Inclusion Criteria:

 -  Males and females ≥ 18 years of age with suspected or confirmed febrile UTI,
 fulfilling at least one of the following signs and symptoms:

 -  Flank pain or suprapubic pain, Tenderness over the kidney on physical
 examination, Urinary symptoms such as dysuria, urinary frequency or urinary
 urgency

 -  Fever ≥ 38.0°C (highest temperature recorded at home or at the hospital)

 -  Positive urinalysis tests (U-Nitrit and/or U-LPK)

 -  Have a pre-treatment baseline urinary culture obtained

 -  Require iv antibacterial treatment of the presumed infection

 -  Fertile women: Agree to practice highly effective anti-contraceptive methods from
 study-start to TOC

 -  Signed informed consent

 Exclusion Criteria:

 -  Have a documented history of hypersensitivity or allergic reaction to any beta-lactam

 -  Pregnant or nursing women

 -  Receipt of any prior potentially therapeutic antibacterial agent within 1 month before
 randomisation and sampling for urine and faecal cultures. Exceptions will prior
 treatment with pivmecillinam or nitrofurantoin.

 -  Known chronic renal insufficiency (creatinine clearance < 10 mL/min at screening as
 estimated by Cockcroft-Gault), or receiving intermittent haemodialysis or peritoneal
 dialysis

 -  Known colonization with ESBL

 -  Any condition or circumstance that, in the opinion of the investigator, would
 compromise the safety of the subject or the quality of study data.
