Single oral dose trimethoprim pharmacokinetics were determined in 18 children aged 3 months to 13 years. Trimethoprim suspension was rapidly absorbed and quickly and widely distributed. The mean clearance was considerably faster and the elimination half life considerably shorter than values reported in adults. Only one third of the administered drug dose was recovered from the urine within 24 h...

Iclaprim, a novel dihydrofolate reductase inhibitor, inhibited 90% of the clinical isolates (MIC(90)) of Streptococcus pneumoniae (n = 785) collected by a national surveillance program at a concentration of 1 microg/ml. The MIC(90) for iclaprim was 7 doubling dilutions lower for trimethoprim-sulfamethoxazole-susceptible isolates (n = 670; MIC(90), 0.06 microg/ml) than for trimethoprim-sulfameth...

A combination of trimethoprim and sulfamethoxazole was effective in the prevention and treatment of Pneumocystis carinii pneumonitis in cortisonetreated rats. Although all of 15 untreated rats died with P. carinii pneumonitis, none of 15 given trimethoprim-sulfamethoxazole prophylactically acquired the infection. After P. carinii pneumonitis was established, 9 of 14 rats recovered after treatme...

We report two cases of daptomycin (DAP)-nonsusceptible (DNS) vancomycin-intermediate Staphylococcus aureus (VISA) vertebral osteomyelitis cases complicated by bacteremia treated with high-dose daptomycin and trimethoprim-sulfamethoxazole. Both patients responded rapidly and favorably to this combination. The clinical isolates from the two patients were tested post hoc in an in vitro pharmacokin...

We compared the effectiveness of rifampin-trimethoprim in fixed combination (3.75:1) to rifampin alone in the eradication of Haemophilus influenzae type b carriage among contacts of patients with invasive infection caused by this organism. The study population was composed of 127 index patients and 620 contacts. Twenty-six percent of contacts were colonized. Rifampin-trimethoprim eradicated car...

OBJECTIVES Vibrio cholerae O1 from a 2006 outbreak in Accra were commonly resistant to multiple antimicrobials and, in particular, to trimethoprim/sulfamethoxazole, drugs commonly used in the treatment of cholera. We sought to determine the genetic basis for trimethoprim/sulfamethoxazole resistance in outbreak isolates. METHODS Twenty-seven isolates from the outbreak were screened by PCR and ...

BACKGROUND Linear IgA bullous dermatosis (LABD) is an autoimmune blistering skin disorder characterized by linear IgA deposits along the dermoepidermal junction. Usually idiopathic, LABD can be drug-induced. OBJECTIVE To report the atypical characteristics of a case of trimethoprim-sulfamethoxazole-induced LABD presenting as toxic epidermal necrolysis (TEN). METHODS A 63-year-old woman trea...

The pharmacokinetics of sulphadoxine-trimethoprim was studied in 6 pre-ruminant calves using two different products. Product A, which contained 200 mg sulphadoxine and 40 mg trimethoprim per mL, was administered intravenously or subcutaneously at a dosage of 25 mg sulphadoxine and 5 mg trimethoprim.kg-1 bodyweight. Product B, containing 62.5 mg sulphadoxine and 12.5 mg trimethoprim per mL plus ...

The in vitro susceptibilities of 130 Xanthomonas maltophilia isolates to 12 antibiotics--trimethoprim-sulfamethoxazole, minocycline, ticarcillin-clavulanate, ceftazidime, cefoperazone, cefoperazone-sulbactam, imipenem, ciprofloxacin, and the investigational quinolones PD 117558, PD 117596, PD 127391, and sparfloxacin--were determined by a microtiter broth dilution technique. Other than the inve...

Objective and Importance. To illustrate the development of spontaneous subdural hematoma secondary to aplastic anemia resulting from the administration of trimethoprim-sulfamethoxazole. This is the first report of trimethoprim-sulfamethoxazole potentiating coagulopathy leading to any form of intracranial hematoma. Clinical Presentation. A 62-year-old female developed a bone marrow biopsy confir...
