Antifungal drug combinations for Cryptococcus neoformans and Prototheca spp.

Seventy-one isolates of Cryptococcus neoformans and 5 isolates of Prototheca spp. were tested for in vitro susceptibility against amphotericin B alone and against the combination of amphotericin B with each clinically relevant concentration of flucytosine (5-FC) and rifampin by broth dilution methods. The combinations of amphotericin B and rifampin produced greater effect on reduction of the minimal inhibition concentration (MIC) of amphotericin B than did either drug used individually. Flucytosine combined with amphotericin B produced little or no reduction of the MIC compared with amphotericin B alone.

An open, non comparative study of ofloxacin i.v. on the treatment of acute symptomatic urinary tract infection.

The clinical efficacy and the safety of ofloxacin i.v. in 35 acute symptomatic urinary tract patients were evaluated. The drug was intravenously administered, 400 mg starting dose then 200 mg once-daily for 3-5 days. The therapeutic success rate and eradication rate in UTI case were 100 per cent in all cases when evaluated immediately after completion of drug treatment, therapeutic success rate and eradication rate at the follow-up evaluation were 97.2 per cent and 91.6 per cent respectively. Also, 5 cases of acute bronchitis and 2 salmonellosis were also administered intravenously, 400 mg once-daily dose and 400 mg twice daily dose respectively. No serious side effects of ofloxacin i.v. therapy were observed in any of our patients.

In vitro activity and clinical evaluation of cefixime in urinary tract infection.

Thirty-five women with uncomplicated acute lower urinary tract infections proven by significant pre-treatment bacteriuria (> or = 10(5)CFU/ml) were treated with an oral dose of 100 mg cefixime twice a day for seven days. Thirty five patients included in this study were checked for response to treatment on the last day of therapy, 7-14 days and 4 weeks post therapy. The clinical response and bacterial eradication rate for cefixime were 91.4 per cent (32/35). The infecting organisms, E. coli and Proteus mirabilis, were inhibited at MIC90 = 0.5 and < or = 0.03 microgram/ml, and MBC = 1 and 0.06 microgram/ml respectively. No adverse events were found in this study.

Cefaclor therapy in uncomplicated cystitis.

Thirty patients with acute urinary tract infection were treated orally with 500 mg of cefaclor three times a day for 7 days. Urine cultures were made before treatment and after therapy. In 97 per cent (29/30) of these patients clinical success was achieved and in 90 per cent (27/30) of them, pathogens were eradicated. Our study showed that cefaclor was still active against most Enterobacteriaceae, such as Escherichia coli and Klebsiella species, the principle pathogens of urinary tract infection. No adverse effects of cefaclor were observed in this study.

Immunobiological diagnosis of tropical ocular diseases: Toxocara, Pythium insidiosum, Pseudomonas (Burkholderia) pseudomallei, Mycobacterium chelonei and Toxoplasma gondii.

Of the sera obtained from 18 patients with ocular diseases comprising ocular larva migrans (OLM), Toxoplasma gondii, Mycobacterium chelonei, Pythium insidiosum bacteria and tumour, 3 sera were positive for Toxocara antibody at the titre over 1/1600 ELISA. All 3 of these sera came from males with unilateral grayish fundi. We demonstrated the value of the direct immunofluorescent assay (DIFA) on vitreous specimens from 7 cases of Toxoplasma retinitis. One vitreous specimen under electronmicroscopic examination revealed bradyzoites of T. gondii. In addition, a few cases of keratoconjunctivitis/ corneal ulcer with endophthalmitis, due to P. insidiosum, Ps. pseudomallei and Mycobacterium chelonei, were also diagnosed.

Value of Clostridium difficile antigen test in immunocompromised hosts in the tropics.

39 fecal and body fluid specimens of immunocompromised patients who developed diarrhoea were tested for Clostridium difficile antigen test. The test was identified in only 11 and in one ascitic fluid. Endoscopy was performed in 5 patients and it showed pseudomembranous colitis in one. Numerous antibiotics were associated with C. difficile related diarrhea: ampicillin, 43%; cephalosporins, 43% and clindamycin, 14%. Three Salmonella sp., and one Entamoeba histolytica were detected among patients who later developed C. difficile associated diarrhea. The effect of oral vancomycin and fusidic acid was demonstrated in patients with C. difficile related diarrhea or colitis. The C. difficile antigen test is promising diagnostic tool in immunocompromised hosts in the tropics where both Salmonella and E. histolytica all are endemic.

Protothecosis following hand injury. A case report.

A case of protothecosis following an accidental cut on the dorsum of the hand by a fragment of glass from an exploding beer bottle is described. The area was widely excised and oral tetracycline given. No recurrence has been seen over a period of four years.

Cryptococcal antigen survey among racing pigeon workers and patients with cryptococcosis, pythiosis, histoplasmosis and penicilliosis.

The cryptococcal antigen latex agglutination system (CALAS) test is simple, sensitive and specific. A total of 129 serum samples, 29 cerebrospinal fluids (CSF) and one ascitic fluid from 143 subjects were tested in the study. Cryptococcal antigenaemia was present in all CSF specimens tested from patients with culture-proven cryptococcal meningitis and cryptococcaemia, and in 91% of tested serum from the same group of patients with cryptococcal meningitis and cryptococcaemia. The occurrence of false positive results among sera obtained from patients with phycomycosis (zygomycosis) due to Mucor spp., Conidiobolus coronata and Pythium spp., and from patients with Penicillium marneffei infections, was not observed. A random survey of 101 high risk subjects, who had fed pigeons for two months up to 40 years, for cryptococcal antigenaemia was also carried out and 4% were positive for cryptococcal antigenaemia. Of 14 Cryptococcus neoformans strains obtained from CSF cultures of patients with cryptococcal meningitis, and with cryptococcaemia, during 1977-1986, ten strains were serotype A and D, and four strains were serotype B and C.

In vitro and clinical evaluation of ofloxacin in urinary tract infection and enteric fever.

During 1984 to 1988, 35 patients with urinary tract infection (UTI) and 37 patients with enteric fever were treated successfully with 400 mg ofloxacin twice a day for 7 to 10 days. Clinical cure or improvement was observed in 31 of the 35 patients with UTI; 32 patients were bacteriologically assessed and eradication was achieved in all of them. Ofloxacin was particularly effective in the treatment of enteric fever in 35 patients; eradication was achieved in all of them; 34 patients were clinically cured within 4 days, however, one patient with bacteraemia due to Salmonella paratyphi A subsequently died, due to his underlying disorder. The MIC90 of the Enterobacteriaceae including Salmonella was less than 0.12 micrograms/ml. Interestingly, beta-lactamase-producing strains of Salmonella and other Enterobacteriaceae in the present study were 28% and 29%, respectively. Ofloxacin therefore offers an effective b.i.d. dosage schedule for enteric fever and UTI due to beta-lactamase-producing bacteria.
