ADRs such as hyperkalemia are more likely to be associated with the use of high-dose TMP-SMX in the ambulatory setting. Clinicians should use caution when initiating high-dose TMP-SMX and consider laboratory monitoring in patients of advanced age or those receiving concomitant ACE inhibitor therapy.

Controversy exists about the most effective treatment options for community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) and about the ability of these strains to develop inducible resistance to clindamycin during therapy. Using both in vitro pharmacodynamic and murine thigh infection models, we evaluated and compared several antimicrobial compounds against CA-MRSA. Strains with inducible macrolide lincosamide-streptogramin type B (iMLS(B)) resistance and strains in which resistance was noninducible were evaluated. Two levels of inocula (10(5) and 10(7)) were evaluated for clindamycin activity in the in vivo model. In both models, the antimicrobial evaluation was performed in triplicate, and bacterial quantification occurred over 72 h, with drug doses that were designed to simulate the free drug area-under-the-concentration-time curve values (fAUCs) obtained from human samples. When the activity of clindamycin against the iMLS(B) strains was evaluated, constitutive resistance was noted at 24 h (MIC of >256), and failure was noted at an inoculum of > or =10(6) in the in vivo models. However, at a low inoculum (10(5)) in the murine thigh-infection model, clindamycin demonstrated modest activity, reducing the CFU/thigh count for clindamycin resistance-inducible strains at 72 h (0.45 to 1.3 logs). Overall, administration of daptomycin followed by vancomycin demonstrated the most significant kill against all strains in both models. Against the clindamycin noninducible strain, clindamycin and doxycycline demonstrated significant kill. Doxycycline, linezolid, and trimethoprim-sulfamethoxazide (not run in the murine model) demonstrated bacteriostatic activity against clindamycin resistance-inducible isolates. This study demonstrates that clindamycin's activity against the iMLS(B) strains tested is partially impacted by inoculum size. At present, there are several alternatives that appear promising for treating clindamycin resistance-inducible strains of CA-MRSA.

The combination of trimethoprim (TMP) and sulfamethoxazole (SMX) is used in the treatment of many common infections such as urinary, respiratory and gastrointestinal tract infections. The aim of this study was to determine TMP and SMX simultaneously in human plasma samples by high performance liquid chromatography (HPLC) using antipyrine as the internal standard. Separation of the compounds was achieved on a reverse-phase C8 column packed with 5 microm dimethyl octadecylsilyl bonded amorphous silica (4.6 mm x 250 mm) column using a mobile phase consisted of potassium hydrogen phosphate, acetonitrile, methanol and water adjusted to pH 6.2. The mobile phase was delivered at a flow rate of 1 mL min- and the effluent was monitored using Max plot technique at 25 derees C. Retention times were 5 min for TMP, 7 min for antipyrine and 9 min for SMX. Quantitation limits were 10 ng mL(-1) for TMP and 50 ng mL(-1) for SMX. Our findings indicated that the developed HPLC method was precise, accurate, specific and sensitive for simultaneous determination of TMP and SMX. Proposed HPLC method was successfully applied for the analysis of TMP and SMX in human plasma after oral administration of a co-trimoxazole tablet to human volunteers.

The level of sICAM-1 in PCP and SMZ groups at the 3rd week [(1.847+/-0.50) ng/ml, (1.787+/-0.59) ng/ml] was lower notably than that at 0 week [(2.407+/-0.81) ng/ml, [(2.478+/-0.59) ng/ml respectively] (P<0.05), and then increased gradually. It was significantly higher in PCP group at 9th week [(3.233+/-0.83) ng/ml] and at 12th week [(3.984+/-0.87) ng/ml] than that of 0 week (P<0.05). Its level in SMZ group at 12th week [(3.621+/-l.62) ng/ml] was also higher than that in 0 week [(2.478+/-0.59) ng/ml] (P<0.05). sICAM-1 level in both PCP and SMZ groups at 9th week and 12th week was higher than that of N group (P<0.05, P<0.01). There was no significant difference between SMZ and PCP groups at 9th week and 12th week (P>0.05).

Two dosage schedules of co-trimoxazole, the standard antibacterial and a 2-day high-dose schedule, were compared with a standard course of chloroquine in the treatment of uncomplicated Plasmodium falciparum malaria. Parasites were cleared from the blood at similar rates, but pyrexia responded more slowly following the standard cotrimoxazole dose. No recrudescences were detected in those observed for up to 60 days after treatment.

A retrospective chart review of hospital and office records was performed on all patients undergoing implant reconstruction performed by a single surgeon (J.M.S.) from August of 2005 to March of 2008. Before 2007, the senior author used 5 to 7 days of cephalosporin prophylaxis. Subsequent to this period, the prophylactic regimen was amended to provide patients with previous chest wall irradiation prophylactic trimethoprim/sulfamethoxazole for 30 days after implant insertion.
Initiated by WHO, a panel of experts in BU and HIV management developed guidance principles for the management of BU-HIV co-infection based on review of available scientific evidence, current treatment experience, and global recommendations established for management of HIV infection and tuberculosis.

This study concern a survey of bacterial resistance to cotrimoxazole; 510 strains of Enterobacteria (167), Vibrio cholerae(206) and Staphylococcus aureus(137) were tested by disc diffusion and agar dilution methods. An interview was conducted with 86 health personals to appreciate the influence of prescription. Staphylococcus aureus were the most susceptible bacteria (13% of resistance), and Vibrio cholerae the most resistant (95%). Related to the gender, Enterobacteria present 43 to 72% of resistance. The data of interview show a very frequent use of cotrimoxazole, related to the disponibility and the accessibility of this drug.

Two hundred twenty-eight consecutive patients were reviewed, ages 0 to 17, presenting at a tertiary care center between 1999 and 2007 with computed tomography proven neck abscesses. Characteristics of patients with differing causative organisms were compared.
Trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis has long been recommended for immunosuppressed HIV-infected adults and children born to HIV-infected women. Despite this, many resource-limited countries have not implemented this recommendation, partly because of fear of widespread antimicrobial resistance not only to TMP-SMX, but also to other antibiotics. We aimed to determine whether TMP-SMX prophylaxis in HIV-infected and/or exposed individuals increases bacterial resistance to antibiotics other than TMP-SMX.

It is postulated that the unstable hydroxylamine metabolite of sulphamethoxazole is responsible for the adverse reactions to co-trimoxazole and in HIV infection systemic glutathione deficiency leads to a reduced capacity to counteract the hydroxylamine toxicity. This hypothesis has been investigated by studying the metabolism of sulphamethoxazole and assessing glutathione status in HIV infection in order to explore the modification of treatment. It is concluded that the toxicity of plasma sulphamethoxazole hydroxylamine is counteracted by normal glutathione concentrations as is the case in HIV-seropositive patients, but that increased oxidation within certain cells in HIV infected individuals may possibly give rise to increased concentrations of reactive intermediates of sulphamethoxazole. Sulphametrole and sulphamethoxazole have similar half-lives but are metabolized differently: in vivo no oxidised metabolites of sulphametrole could be detected. In a retrospective study the rate of adverse reactions to trimethoprim-sulphametrole appeared to be in the lower range of those reported for trimethoprim-sulphamethoxazole indicating that the combination of trimethoprim-sulphametrole may be more favourable. The ratio of trimethoprim:sulphonamide is 1:5, but in-vitro studies with Toxoplasma gondii indicate that because of the synergic effect of both agents the dose of sulphonamide is possibly unnecessarily high.

Urinary tract infections (UTI) are common in renal transplant recipients. Trimethoprim/sulfamethoxazole (TMP/SMZ) in moderate to high daily doses prevents Pneumocystis jiroveci (PCP) and reduces the risk of UTI in renal transplant patients. Low-dose TMP/SMZ also reduces the risk of PCP, although its ability to reduce the risk of UTI is uncertain.

Pentamidine isethionate and sulfamethoxazole-trimethoprim are effective in the treatment of Pneumocystis carinii pneumonia in the immunosuppressed pediatric patient. To compare their efficacy and toxicity, 25 pediatric cancer patients with biopsy-proved P carinii pneumonia were randomly assigned to receive either pentamidine intramuscularly or sulfamethoxazole-trimethoprim orally for 14 days. No differences in response or frequency of side effects were noted between the two drug regimens, with recovery occurring in 24 (96%) of 25 children. Skin eruptions and hematologic abnormalities were the most common side effects of sulfamethoxazole-trimethoprim therapy, while local reactions at injection sites, abnormal renal function, and hypoglycemia were the most frequent complications of pentamidine treatment. The ease of administration and less serious side effects of sulfamethoxazole-trimethoprim make it the drug of first choice for treating P carinii pneumonia. Pentamidine remains an important drug for patients who fail to respond to this initial therapy.
Chronic infection of the prostate with gram-negative bacterial pathogens (mainly coliforms) is a common cause of recurrent urinary tract infections in men. Cure of prostatic infection is difficult because most antimicrobial agents useful against the causative organisms diffuse poorly into prostatic fluid. Pharmacokinetic studies in dogs show that trimethoprim readily reaches therapeutic levels in prostatic fluid, yet clinical studies indicate that only about one-third of men with chronic bacterial prostatitis are cured of infection after prolonged therapy with trimethoprim-sulfamethoxazole. A profound secretory dysfunction of the prostate, characterized by increased alkalinity of solute-poor secretions, often accompanies bacterial prostatitis. Undoubtedly, this secretory dysfunction adversely affects the accumulation of trimethoprim in prostatic fluid and thus accounts for the failure of therapy in some instances. In addition. infected prostatic calculi may account for more such failures than previously realized.

Immunodeficiency can occur both in patients undergoing radiation therapy, as well as in patients who have had thymectomies. However, few studies have examined the immune recovery of a patient following both procedures. We aim to emphasize the need for assessment and consistent monitoring of patients with thymoma prior to and after combined treatment of thymectomy and radiation, both of which are likely to result in an increased risk for immunodeficiency.
The epidemic was brought under control with the reinforcement of nosocomial transmission measures and with systematic nasal decontamination with mupirocin of all patients admitted to the HIV unit. Molecular typing techniques showed the existence of two epidemic strains: strain A was present in the 12 patients admitted to the HIV unit and strain B in the remaining 3 patients hospitalized elsewhere.

The amikacin-carbenicillin-cotrimoxazole combination was used as an empiric treatment for febrile episodes in patients with acute leukemia and severe granulocytopenia. The choice of drugs was based on the finding in our institute that the majority of infections are caused by gram-negative rods, particularly Pseudomonas, with high percentage of strains resistant to gentamycin and tobramycin. Granulocyte transfusions were given to the patients who did not show satisfactory clinical improvement 48 h after start of antibiotic therapy. There were cures in 84.6% of the febrile episodes treated with this antibiotic combination, including five of eight episodes of microbiologically confirmed bacteremia. Survival after 21 days of antibiotic therapy amounted to 89.1%. Renal toxicity occurred in 10.9% of the episodes treated. The prompt use of this antibiotic combination seems to be a safe and efficacious therapeutic tool for treating these high-risk patients.

234 patients' records were reviewed and 19% of the patients had received cotrimoxazole prophylaxis. PCP prevalence was 36% which was diagnosed mainly by clinical examination and sometimes with the additional help of chest X-rays. Of those who were on prophylaxis, 75% were on primary prophylaxis and the rest on secondary prophylaxis. All patients on prophylaxis were using cotrimoxazole, with the 960 mg once daily dosing being the most common regimen (96%). Receiving prophylaxis was associated with being female (p = 0.0067), widowed (p = 0.012), and taking ARV therapy (p = 0.0026). Prophylaxis significantly reduced mortality (p = 0.0017). The development of PCP was associated with a history oftuberculosis relapse (p = 0.022).

Culture of Tropheryma whippelii has been established only once, in human fibroblast cell lines from a heart valve inoculum. Molecular-based diagnostic techniques, although highly sensitive, may be less specific. New diagnostic tools involving isolation of bacteria from contaminated intestinal biopsies and immunohistological detection need to be developed.
