Sixty-four women with an uncomplicated urinary tract infection were randomly allocated to receive treatment with either an 0.96 g, 1.92 g or 2.88 g single oral dose of co-trimoxazole or a conventional five-day course of co-trimoxazole. The success of each group was comparable although it is suggested that a single dose should be at least 1.92 g (four tablets Septrin or Bactrim). This study confirmed previous work that single dose therapy was effective and well tolerated, preferred by the patients and side effects were minimal. This approach to treatment should be strongly encouraged.

Cotrimoxazole (trimethoprim/sulfamethoxazole [TMP-SMX]) is an alternative treatment for toxoplasmic encephalitis because it is inexpensive, well-tolerated, and as effective as pyrimethamine-sulfadiazine, which is the first-line drug regimen). We report results of a large cohort study of patients with acquired immunodeficiency syndrome who were treated for toxoplasmic encephalitis with cotrimoxazole. The mean follow-up period was more than three years. Our results confirm that cotrimoxazole is effective (85.5%), with a relatively low incidence of side effects (22%; 7.4% requiring treatment interruption). Relapse occurred in 30.1% of the patients at a mean +/- SD of 7.8 +/- 16.2 months after the first episode. The only risk factor for relapse was poor treatment and/or prophylaxis adherence. Mortality was significantly higher (P < 0.05) before 1996 than after 1996 (the era of highly active antiretroviral therapy). There was a non-significant trend towards a higher rate of relapse among patients treated before 1996 (P = 0.06). Consequently, cotrimoxazole could be a first-line drug regimen for curative treatment and prophylaxis of toxoplasmic encephalitis.

The confirmed pharmacological treatment of cerebellar ataxia is still lacking. In a recent preliminary trial, we showed that D-cycloserine, a partial NMDA allosteric agonist, may relieve the symptoms. In this paper, major clinical trials to relieve ataxic symptoms are reviewed. Previous studies showed some efficacy of physostigmine in ataxic patients. However, physostigmine did not improve the ataxia in a recent double-blind crossover study. The replacement therapy of the deficient cholinergic system with choline or choline derivatives was tried in patients with Friedreich's ataxia and other ataxic patients, but the result was not definitive. A levorotatory form of hydroxytryptophan (a serotonin precursor), a serotoninergic 5-HT1A agonist, a serotoninergic 5-HT3 antagonist, and a serotonin reuptake inhibitor were also used for the therapy for ataxia. In a double-blind randomized study, buspirone, a 5-HT1A agonist was active in cerebellar ataxia, but the effect is partial and not major. The effects of the studies with the other serotoninergic drugs were not consistent. The effect of sulfamethoxazole-trimethoprim therapy in spinocerebellar ataxia type3/Machado-Joseph disease (MJD) was reported, although the therapy improved spasticity or rigidity, rather than ataxia. In contrast to previous studies, sulfamethoxazole-trimethoprim therapy in MJD had no effect in a 2001 double-blind crossover study. The thyrotropin-releasing hormone, D-cycloserine, and acetazolamide for SCA6 may have some efficacy. However, a well-designed double-blind crossover trial is needed to confirm the effect.

A 61 year old RGP lens wearer with a history of nonresponsive keratitis of the right eye which involved the graft margin was referred to us for treatment. Corneal cultures revealed growth of a gram-negative rod on the fifth day and the organism was subsequently identified as Alcaligenes xylosoxidans, which was resistant to most antibiotics and sensitive only to Bactrim, Timentin, and imipenem.

The most effective strategy, initiation of co-trimoxazole prophylaxis at WHO stage > or = 2, increased undiscounted life expectancy by 5.2 months, discounted life expectancy by 4.4 months, and lifetime costs by US dollars 60, compared with no prophylaxis. Delaying prophylaxis initiation until WHO stage >or = 3 was less costly and less effective. All CD4-based strategies were dominated. The incremental cost-effectiveness of early versus late co-trimoxazole prophylaxis initiation was US dollars 200/year of life gained. Results were stable despite wide variations in plausible assumptions about bacterial resistance and the prophylaxis efficacy on co-trimoxazole-resistant strains.

Group B streptococcus (GBS) is the major cause of bacterial sepsis and meningitis in neonates and poses a significant threat to parturient women. Recently, we identified in GBS the polypeptide PcsB, which is a protein required for cell separation of GBS, and which is also involved in the antibiotic sensitivity of these bacteria. In the present study, the introduction of the pcsB-carrying plasmid pATpcsB into the PcsB-deficient GBS mutant Sep1 restored the phenotype and the antibiotic susceptibility of this strain to that of the GBS wild-type. Although Northern blots revealed a four- to five-fold increased transcription of pcsB in pATpcsB-carrying GBS strains, overexpression of pcsB did not result in higher amounts of PcsB in the cell wall and in the culture supernatant of GBS, indicating regulatory mechanisms that control the translation or secretion of PcsB in these bacteria. In the culture supernatant of mutant Sep1 significant amounts of enolase were identified. As this protein was also present in extracts of cell wall-bound proteins from the GBS wild-type, it can be speculated that GBS can translocate enolase across the cytoplasmic membrane. Northern blot analysis exhibited similar expression of the enolase gene in the GBS strains 6313 and Sep1, indicating that mutant Sep1 is impaired in the anchoring of this protein to its cell wall.

In a prospective randomized double-blind trial, pivmecillinam was compared with cotrimoxazole (TMP-SMX), both given orally for a period of 5 days, for the treatment of 59 children with shigellosis. 29 patients were treated with pivmecillinam and 30 with cotrimoxazole. 14% of shigella organisms isolated were resistant to pivmecillinam and 21% to TMP-SMX. The diarrhea persisted for a mean (+/- SD) period of 74 +/- 24.8 h in the pivmecillinam-treated patients versus 73.8 +/- 34 h in the TMP-SMX-treated patients. Duration of fever, positive stool culture, visible blood, occult blood, and pus cells in the stools were similar for both treatment groups. Five patients (17%) in the pivmecillinam group and 4 patients (13%) in the cotrimoxazole group fulfilled the clinical criteria that defined treatment failure. One patient (3.4%) in the pivmecillinam group and 2 (6.6%) in the TMP-SMX group evidenced recurrence of the diarrheal symptoms at the follow-up visit. No major drug-related side effects were observed in either group. We concluded that pivmecillinam is equivalent to cotrimoxazole in the treatment of shigellosis in children.
Whipple's disease (WD) is a chronic infection caused by Tropheryma whipplei. A 1-year treatment of oral trimethoprim/sulfamethoxazole (SXT) is commonly used. Advances in the culture of T. whipplei have allowed for full genome sequencing and antibiotic susceptibility testing, which has demonstrated resistance of T. whipplei to trimethoprim. Several mutations in the folP gene that encodes dihydropteroate synthase, the target of sulphonamides, has been reported for one patient with clinically acquired resistance to SXT. Here we report three new patients who experienced clinically acquired resistance to SXT during treatment and one patient with biological failure. Sixty-two folP sequences from DNA samples of 59 WD patients were also obtained. Among the detected amino acid changes, two positions (N4S and S234F) significantly predicted secondary sulfamethoxazole failure (four of five). We suggest that these mutations should be detected at the time of WD diagnosis by sequencing folP in order to avoid sulfamethoxazole monotherapy.

The two groups were comparable at baseline, except for the severity of the P. jiroveci pneumonia. Hyperkalaemia developed in seven patients: all in the prednisolone and trimethoprim-sulfamethoxazole group. The greater incidence of hyperkalaemia in this group is surprising and was counter to our expectation.
In northern Israel, ampicillin, cephalexin and TMP-SMX cannot be used empirically in the treatment of community-acquired UTI. Post-menopause and recurrent UTI are independent factors associated with TMP-SMX resistant pathogens in women.

Burkholderia pseudomallei is the causative agent of melioidosis, a disease endemic in tropical and subtropical regions of South-East Asia and Northern Australia. Antimicrobial therapy regimens for treatment of acute septicemic melioidosis are of variable efficacy. Ceftazidime is the current antibiotic of choice and is commonly administered with other agents such as cotrimoxazole or doxycycline. The emergence of resistant strains of B. pseudomallei and the persistence of high mortality rates prompted the present study. Using an established mouse model of acute disseminated B. pseudomallei infection, we compared the efficacy of ceftazidime versus cefpirome in combination with cotrimoxazole or chloramphenicol therapy in vivo. Control mice that were infected but did not receive antibiotic therapy died within 96 hours of infection. No deaths occurred in treatment groups receiving either cephalosporin or cotrimoxazole, despite the demonstrated resistance of B. pseudomallei to cotrimoxazole in vitro. The mortality rate in treatment groups receiving either cephalosporin and chloramphenicol was 66%. These results demonstrate a comparable level of efficacy between ceftazidime and cefpirome for treatment of acute B. pseudomallei infection in mice.
