Results of measurements of Trimethoprim-Sulphamethoxazole (Bactrim, Eusaprim) levels in the CSF of seven patients with intact meninges are reported. The maximum fluid concentration of non-protein-bound SMZ was approximately 46.5%. The TMP value was 68.9%. With this combination of drugs it is possible to achieve a high CSF level of broadspectrum chemotherapeutic substances in neurosurgical patients.

Pneumocystis carinii pneumonitis (PCP) is fatal in 90 to 100% of the cases if no treatment is given. Trimethoprim-sulfamethoxazole (TMP-SMX) was used at one of two dosage levels in the treatment of 20 children with PCP and cancer. Of 14 patients treated with 20 mg TMP--100 mg SMX/kgd, 12 recovered and 2 died. Treatment of the fatal cases and one of the patients who recovered was supplemented with pentamidine. When six patients were treated with 4 to 7 mg TMP--20 to 35 mg SMX/kgd, four recovered and two died. Both fatal cases and one of the patients who recovered were also treated with pentamidine. There was no significant adverse effects from TMP-SMX.

Trimethoprim-sulfamethoxazole (TMP-SMX) caused no significant changes in the blood glucose or insulin concentrations of diabetic subjects treated by dietary measures alone or by insulin and diet. In only one of eight subjects receiving oral hypoglycemic agents for the control of diabetes did a significant immediate increase in immunoreactive insulin follow administration of TMP-SMX. In the same patient hypoglycemic symptoms were present after the agent had been taken for 14 days.

In 33 consecutive AIDS patients with a first episode of Pneumocystis carinii pneumonia (PCP) we evaluated treatment, outcome, recurrence rate and pyrimethamine as chemoprophylaxis in a 1-year follow-up. Only 2 patients had a CD4 lymphocyte cell count greater than 0.2 X 10(9)/l. Trimethoprim-sulfamethoxazole (TMP-SMX) was initially given to 32 patients but in 20 of these patients severe adverse reactions caused us to discontinue treatment. Of these 20 patients 11 were started on i.v./i.m. pentamidine but in 6 adverse reactions forced us to withdraw pentamidine. Patients were retrospectively divided with regard to duration of therapy into 2 groups. We could not find any difference between patients in Group 1 treated for less than or equal to 14 days and patients in Group 2 treated for greater than 14 days when comparing outcome, number of recurrences and mean time until recurrence. In 16/21 patients given only TMP-SMX initially in a high dose (means = 16 mg trimethoprim/kg/day), dose reduction was performed to means = 10.5 mg trimethoprim/kg/day after a mean time of 6.9 days. The case-fatality rate for these patients was 10% (2/21) and the overall case-fatality rate was 15% (5/33). We chose pyrimethamine (50-175 mg/week) as secondary prophylaxis for PCP. At 1-year follow-up another 16 patients had died (21/32) and 9/27 (33%) discharged patients had had one recurrence each of PCP. All recurrences occurred among patients treated with only TMP-SMX for the acute episode of PCP. Of these 27 discharged patients 23 had been given pyrimethamine and 8 (36%) of these had experienced a recurrence.(ABSTRACT TRUNCATED AT 250 WORDS)

The infectious complications of the acquired immunodeficiency syndrome (AIDS) are discussed, and the conventional and nonconventional therapies used for these infections are reviewed. The infections most commonly encountered in patients with AIDS are Pneumocystis carinii pneumonia (58%), Candida esophagitis (31%), toxoplasmosis (21%), cytomegalovirus infections (15%), and herpes-simplex virus infections (12%). Pneumocystis carinii pneumonia is the most common life-threatening process in these patients. Trimethoprim-sulfamethoxazole (TMP-SMZ) is considered the drug of choice for its treatment. Oral candidiasis often indicates the progression to AIDS in the high-risk populations of homosexual or bisexual men, intravenous drug abusers, and individuals with hemophilia. Nystatin suspension is commonly used to treat oral candidiasis, while Candida esophagitis demands systemic therapy with ketoconazole. Toxoplasmosis most commonly manifests itself in patients with AIDS as a cerebral mass lesion. The recommended therapy includes sulfadiazine and pyrimethamine. AIDS patients frequently experience protozoal invasion of the intestinal tract with Giardia lamblia, Isospora belli, and Cryptosporidium muris. Various drugs have been tried for these infections, including quinacrine hydrochloride, metronidazole, TMP-SMZ, and spiramycin. Cytomegalovirus (CMV) infections commonly involve the lungs, gastrointestinal tract, eyes, brain, and nervous system. Attempts to treat these disseminated CMV infections with antiviral agents, including acyclovir, have not been successful. However, acyclovir has been found beneficial in the treatment of herpes-simplex virus infections. Multiple infectious complications may occur in patients with AIDS as a result of the cellular-immune deficiency associated with this disease. Until more research is done with AIDS patients, therapy must be based on the data available from the treatment of these infections in immunosuppressed patients without AIDS.

We compared the infections encountered in 23 renal transplant patients given the monoclonal anti-T-cell antibody, Orthoclone OKT3 (OKT3), for treatment of steroid-resistant rejection in 1986 and in 23 control patients from 1984 to 1985 with resistant rejection matched demographically, for severity of rejection and for risk factors predisposing to infection, who did not receive OKT3; recipients of OKT3 received substantially less prednisone, cyclosporine, and antilymphocyte globulin (ALG) than control patients for treatment of the rejection episode. Fourteen (61%) patients given OKT3 developed one or more infections in the 3-month period following treatment as compared with 9 control patients (39%) given conventional antirejection therapy with high-dose steroids and, usually, ALG. Patients given OKT3 were significantly more likely to develop serious infections (pneumonia, bacteremia, meningitis, or severe viral infection; 16 episodes vs. 4, P = .02). Six recipients of OKT3 (26%) acquired infections typically encountered in states associated with depressed cell-mediated immunity (CMI)--Listeria sepsis (2), disseminated nocardiosis and Mycobacterium tuberculosis infection (1), cytomegalovirus (CMV) pneumonia (1), Yersinia infection with severe dermatophytosis (1), and Epstein-Barr virus-associated lymphoproliferative syndrome (1)--as compared with 1 case of mild CMV infection in the control group (P = .08). Trimethoprim-sulfamethoxazole (TMP-SMZ) was given to 19 patients in each group; all 4 recipients of OKT3 who did not receive TMP-SMZ prophylaxis developed life-threatening infection, 3, bacteremia (2 with Listeria) and 1, disseminated nocardiosis and M tuberculosis infection. These data suggest that OKT3 given for treatment of resistant rejection in renal transplantation predisposes the patient to serious infection, particularly with opportunistic pathogens characteristically associated with depressed cell-mediated immunity. Prophylaxis with TMP-SMZ, which is safe, well tolerated, and effective for reducing the incidence of infection in renal transplantation, may be especially important during OKT3 therapy.

Trimethoprim-sulfamethoxazole (TMP-SMZ) has been associated with hemolytic anemia in patients deficient in glucose-6-phosphate dehydrogenase (G-6-PD). The effect of a daily dose of SMZ of 50 mg/kg was evaluated in a double-blinded study that compared vancomycin with TMP-SMZ given intravenously for treatment of serious Staphylococcus aureus infections. Levels of G-6-PD were determined when patients entered the trial. Most patients were black Americans. G-6-PD-deficient patients were followed serially, with determinations of hemoglobin, haptoglobin, and bilirubin levels, reticulocyte count, and urinalysis. Pretherapy hemoglobin levels were compared with levels during and after therapy. One hundred patients were divided into four groups: group A comprised G-6-PD-deficient patients receiving TMP-SMZ (n = 20); group B, G-6-PD-deficient patients receiving vancomycin (n = 25); and groups C and D, patients with normal G-6-PD levels receiving TMP-SMZ (n = 24) and vancomycin (n = 31), respectively. Groups were comparable in terms of age of patients and duration of therapy. Hemolysis did not occur in any patient receiving TMP-SMZ and occurred in only one patient receiving vancomycin. Both this study and published reports indicate that TMP-SMZ rarely causes hemolysis in a G-6-PD-deficient population.

Trimethoprim-sulfamethoxazole (TMP-SMZ) has traditionally been employed as an oral formulation for infections in ambulatory pediatric patients. However, therapeutic concentrations of TMP and SMZ in serum and CSF are more consistently attained after intravenous administration. Serum half-life increases with the age of the child, and few significant toxic effects are observed with intravenous administration. Either the necessity to optimize bioavailability because of the underlying seriousness of disease or a desire to avoid other drugs that may be responsible for adverse reactions or hypersensitivity should direct the clinician to administer an intravenous preparation. Serious pediatric infections that might warrant the consideration of intravenous TMP-SMZ include shigellosis, salmonellosis, typhoid fever, nocardiosis, gram-negative bacillary septicemia or meningitis, and infections due to Pneumocystis carinii and malarial parasites. Infections due to Listeria will respond to TMP-SMZ, and infections due to Citrobacter diversus, Acinetobacter species, Pseudomonas cepacia, and Flavobacterium meningosepticum are especially susceptible to TMP-SMZ.

Actinomycetoma (Madura foot) caused by Actinomadura madurae occurred in an Indiana factory worker. Previous cases of culture-proven actinomycetoma from the United States and reports of drug therapy were reviewed. Treatment with sulfonamides, streptomycin, dapsone, and other antimicrobial agents has been effective. Trimethoprim-sulfamethoxazole (TMP-SMZ) therapy was effective in our case, but sulfadiazine was not. In vitro, SMZ was 16 times more active against the infecting strain of A. madurae than was sulfadiazine, and TMP was inactive, suggesting that our patient's satisfactory treatment might have been due to SMZ alone. Prolonged therapy is usually necessary. Relatively simple immunologic procedures and antimicrobiol susceptibility tests have been useful in the diagnosis and management of actinomycetoma. With appropriate antimicrobial therapy, surgical excision or amputation usually can be avoided. Recommendations for the medical management of actinomycetoma are summarized.

Trimethoprim-sulfamethoxazole (TMP-SMZ) was used for treatment of 34 patients with pulmonary or cutaneous nocardiosis. Of nine patients with primary cutaneous disease, eight had rapid resolution of their infection after short-term therapy and none have relapsed after a follow-up of more than six months. The 25 patients with pulmonary nocardiosis had a good clinical response, but three of five (60%) who completed less than three months of therapy relapsed within four weeks. Of the 10 patients who completed four to six months of therapy, only one (10%) relapsed and this relapse was due to drug resistance. By the method of serial dilution in agar, 96% of 59 isolates of Nocardia had MICs of SMZ of less than 25 micrograms/ml. Fewer than 20% were susceptible to 2.5 micrograms of TMP/ml. Synergy between TMP and SMZ was usually present with ratios of TMP to SMZ of 1:5, 1:1, or 5:1, but was less common at a ratio of 1:20. Disk susceptibility testing was easy to perform and readily separated sensitive from resistant strains. TMP-SMZ is highly effective for the treatment of nocardiosis, but the question of whether it is more effective clinically than a sulfonamide alone remains unanswered.
