Intestinal tuberculosis in patients with fever of unknown origin in Egypt.
Nineteen patients with intestinal tuberculosis were admitted to the Abbassia Fever Hospital in the period 1991-1997. Fever, abdominal pain, diarrhea, and weight loss were the most common symptoms. Small bowel radiology and colonoscopy were helpful in establishing the diagnosis. The difficulties in diagnosing tuberculous enteritis and the need to consider seriously the possibility of this disease in such patients is most important and is discussed.

Extra-pulmonary tuberculosis in patients with fever of unknown origin: clinical features and diagnosis.
One hundred twenty-nine patients with extra-pulmonary tuberculosis admitted at the Abbassia Fever Hospital, NAMRU-3 during a seven year period (1991 to 1997) are described. Tuberculous peritonitis was diagnosed in 35 patients, tuberculous lymphadenitis in 32, intestinal tuberculosis in 19, genito-urinary tuberculosis in 14, skeletal tuberculosis in 13, disseminated miliary tuberculosis in 11, and splenic tuberculosis in 5 patients. The clinical picture included fever, and weight loss accompanied by anaemia and an elevated erythrocyte sedimentation rate in all patients.

Azithromycin compared with rifampin for eradication of nasopharyngeal colonization by Neisseria meningitidis.
OBJECTIVES: To evaluate the efficacy and safety of azithromycin compared with rifampin for eradication of nasopharyngeal carriage of Neisseria meningitidis METHODS: Pharyngeal swabs were obtained from 500 students attending nursing school in Cairo, Egypt, to determine the colonization rate with N. meningitidis. Colonized individuals were randomized to receive azithromycin (500 mg once) or rifampin (600 mg twice daily for four doses). Subjects were then recultured 1 and 2 weeks posttreatment to determine the effectiveness of the antibiotic therapy for eradication of meningococcal nasopharyngeal colonization. RESULTS: Individuals treated with azithromycin had a 93% eradication rate at 1 and 2 weeks posttreatment comparable with 95 and 91%, respectively, for rifampin. No significant side effects were reported by any subjects treated with either antibiotic. CONCLUSION: Azithromycin is effective in the eradication of N. meningitidis from the nasopharynx of asymptomatic colonized individuals and deserves further evaluation for use as prophylaxis against N. meningitidis.

Tuberculosis meningitis, Abbassia Fever Hospital-Naval Medical Research Unit No. 3-Cairo, Egypt, from 1976 to 1996.
A total of 1,430 patients with the presumptive diagnosis of tuberculous meningitis were admitted to the U.S. Naval Medical Research Unit No. 3/Abbassia Fever Hospital in Cairo, Egypt from January 1976 to January 1996. Diagnosis was confirmed by culture of the mycobacteria from the cerebrospinal fluid CSF of 857 patients and these patients are included in the final analysis. There were 497 males and 360 females. The patients ranged in age from five months to 55 years. The number of patients admitted during the months of March, April, and May were more than double those admitted during October, November, and December. The duration of symptoms prior to admission ranged from seven to 90 days (mean = 29.5 days). Upon admission, 4% of the patients were alert, 34% were drowsy, and 62% were in a coma. Of the 857 patients studied, 490 (57%) died, 256 (30%) recovered completely, and 11 (13%) recovered with sequelae. The mortality and neurologic sequelae were directly related to the stage of disease and duration of symptoms prior to admission. Mortality was significantly lower in patients admitted in stage II and or with short duration of disease compared with those in stage III and or with prolonged duration of symptoms prior to admission. The use of dexamethasone in patients with tuberculous meningitis significantly reduced the ocular complications that occur in these patients and also significantly reduced the fatality rate.

Focal lesions of the spleen in patients with fever of unknown origin: sonographic patterns and diagnosis.
A review of ultrasonic scans performed for 811 patients admitted at the Abbassia Fever Hospital between 1990 through 1996 for investigation of fever undiagnosed for over 3 weeks revealed 28 cases of focal splenic lesions. They included lymphoma in sixteen cases, tuberculosis in six cases, echinococcal cysts in three, abscess in two, and infarction in one. Final diagnosis was obtained by correlating the ultrasonography and clinical findings, together with pathologic, bacteriologic, serologic and angiographic data.

Schistosoma mansoni antigens applicable to diagnosis of prepatent infections.
Diagnosis of schistosomiasis still depends upon demonstration of eggs in excreta, by which time significant pathology may occur to the human host. This study was undertaken to identify Schistosoma mansoni antigen(s) to be exploited in serodiagnosis of prepatent and/or acute infections. Immunoglobulin G and M responses of inbred and outbed mice to Schistosoma mansoni whole adult worm antigen were monitored in immunoblots using sera obtained at sequential times from mice infected with either 600 or 100 Schistosoma mansoni cercariae each. Regardless of the initial infection dose, immunoblot reactions to two doublets, 31/32 and 34/35 kDa appeared as early as two and three weeks post infection respectively and reactions to 38 and 70 kDa antigens appeared after five weeks infection. Antigens 31/32 and 38 induced both IgG and IgM responses whereas 34/35 and 70 predominantly induced IgG response. Homologues of these four antigens equally reactive with serum of infected mice were also demonstrated in Schistosoma haematobium, worms. Examination of sera from 25 patients suffering from acute Schistosoma mansoni, two suffering from Schistosoma haematobium and 16 patients suffering from infections with other parasite species confirmed the potential of 31/32, 34/35 and 38 kDa antigens in the specific diagnosis of prepatent and acute schistosomal infections but showed cross-reactivity of the 70 kDa antigen.

The value of the tuberculin skin test in patients with tuberculous meningitis.
To determine the clinical utility of the tuberculin purified protein derivative (PPD) skin test in patients suspected of having tuberculous meningitis (TBM), the test was applied on admission to 180 patients suspected of having tuberculous meningitis and to 50 patients with proven bacterial meningitis admitted to the Abbassia Fever Hospital, Cairo, Egypt, during the period 1987 to 1989. Admission tuberculin positivity in evaluated groups revealed the following: overall suspect TBM cases--17% (31/180), culture-confirmed TBM cases--19% (16/83), and culture-confirmed acute bacterial meningitis cases--14% (7/50). Repeat PPD skin test at 60 days in surviving presumptive/confirmed TBM cases revealed a significant increase in tuberculin positivity to 62% (58/93) from admission (p < 0.001). Evaluation of PPD positivity by clinical stage of TBM revealed 36% positivity in alert patients as compared to 12% positivity in comatose patients (p = 0.01). Admission tuberculin skin testing as a diagnostic aid for clinical management of tuberculous meningitis is of limited utility in our study population because of the high prevalence of tuberculin positivity in the Egyptian population (potential false positive correlation with the acute presentation) and the advanced stage of TBM at presentation to Egyptian public hospitals (potential false negative correlation).

Short course chemotherapy with cefixime in children with multidrug-resistant Salmonella typhi Septicaemia.
Increasing prevalence of multidrug-resistant (MDR) Salmonella typhi strains in pediatric cases of typhoid fever and chemotherapy restrictions in children, such as fluoroquinolones, require ongoing clinical evaluations of different antibiotic regimens. Previously reported clinical trials with oral cefixime therapy given as a 12-day regimen (20-30 mg/kg divided twice daily) demonstrated both safety and efficacy. An open trial was undertaken to investigate a short course (8-day) regimen of oral cefixime in an Egyptian public fever hospital. Eighty children were initially enrolled with blood culture confirmation in 60 children. Clinical cure was documented in 57 (95 per cent) with three children requiring a change in antibiotic regimen due to therapeutic failure and one child with culture-confirmed relapsed 21 days post-therapy. All S. typhi isolates were sensitive to cefixime as measured by disk diffusion. Cefixime was well-tolerated with only mild side-effects, including nausea/vomiting (8 per cent) and abdominal cramping with loose stools (6 per cent), which may have been secondary to typhoid fever. Cefixime given in a short 8-day course is safe and effective in the management of MDR typhoid fever in children.

Comparison of the efficacy, safety and cost of cefixime, ceftriaxone and aztreonam in the treatment of multidrug-resistant Salmonella typhi septicemia in children.
An increase in the incidence of Salmonella typhi strains resistant to chloramphenicol, ampicillin and trimethoprim-sulfamethoxazole causing enteric fever in Egyptian children stimulated the evaluation of alternative drugs. Children with positive blood cultures were treated with cefixime, ceftriaxone or aztreonam, and the efficacy, safety and cost of these regimens were evaluated and compared. Cefixime (7.5 mg/kg) was given orally twice daily to 50 children for 14 days, ceftriaxone (50 to 70 mg/kg) was given im once daily for 5 days to 43 children and aztreonam (50 to 70 mg/kg) was given im every 8 hours for 7 days to 31 children. Children in the 3 groups were comparable with regard to age, sex, duration and severity of illness before admission. All children were cured. A significant difference (P < 0.05) in duration of treatment before becoming afebrile seemed to favor ceftriaxone (3.9 days) over aztreonam (5.5 days) and cefixime (5.3 days). During the 4-week follow-up period relapses occurred in 3 (6%) children in the cefixime group, in 2 (5%) in the ceftriaxone group and in 2 (6%) in the aztreonam group. Safety and efficacy were comparable for all 3 drugs. Ceftriaxone was most cost-effective on an inpatient basis, because of a more rapid clinical cure, and cefixime was the most cost-effective on an outpatient basis, because of drug cost.

Short-course norfloxacin and trimethoprim-sulfamethoxazole treatment of shigellosis and salmonellosis in Egypt.
In a double-blind clinical study, 109 adult Egyptian patients infected with Shigella spp. and 45 infected with Salmonella spp. were randomly assigned to three treatment groups: 1) norfloxacin in a single 800-mg dose, 2) norfloxacin, 400 mg twice a day for three days, and 3) trimethoprim (160 mg)-sulfamethoxazole (800 mg) (TMP-SMX), twice a day for three days. Among Shigella-infected patients, diarrheal symptoms had resolved in 86-97% and bacteriologic failure (repeat positive stool culture) occurred in only two patients five days after the start of the three treatment regimens. Among Salmonella-infected patients, diarrheal symptoms had resolved in 76-82% of patients and bacteriologic failure was common (18-36%) five days after the start of therapy. These data indicate that short-course therapy with either norfloxacin or TMP-SMX can be effectively used to treat shigellosis in adults in developing countries. However, for uncomplicated Salmonella spp. infection, short-course therapy with norfloxacin and TMP-SMX may not lead to a rapid resolution of symptoms or consistently eliminate this enteropathogen.

Meningitis and encephalitis at the Abbassia Fever Hospital, Cairo, Egypt, from 1966 to 1989.
A total of 7,809 patients with meningitis or encephalitis were admitted to the Abbassia Fever Hospital in Cairo, Egypt from November 1, 1966 to April 30, 1989. The etiology was Neisseria meningitidis (mostly group A) in 27.3% of the patients, Mycobacterium tuberculosis in 19.7%, Streptococcus pneumoniae in 7.3%, and Haemophilus influenzae in 4.1%. Almost 27% of the cases had purulent meningitis but without detectable etiology; however, the epidemiologic data suggest that most of these had meningococcal meningitis. Encephalitis was suspected in 12.5% of the patients. Most of the meningococcal, pneumococcal, and Haemophilus cases occurred during the winter months. The number of meningococcal and culture-negative purulent cases per year reached a maximum three times during the 22.5 years of this study. There were more males than females in all etiologic groups, with the ratio for the total patient population being 1.6:1. The average age ranged between 11.7 and 16.5 years for all groups except for Haemophilus patients, who had a mean age of 2.5 years. The mortality rate was almost 55% for tuberculous patients and was approximately 40% for both pneumococcal and Haemophilus patients; it was 8.5% in patients with meningococcal disease.

Cefixime in the treatment of enteric fever in children.
Cefixime in a dose 20 mg/kg/day, orally, divided into two doses 12 h apart for a minimum of 12 days, was administered to 50 children with proven S. typhi septicaemia. Forty four of the patients were infected with strains of S. typhi resistant to multiple antibiotics including chloramphenicol, ampicillin and trimethoprim-sulfamethoxazole. All patients responded rapidly to treatment and were cured clinically and bacteriologically. Fever subsided within a mean of 5.3 days (range 3-8 days). Only two of the 50 patients treated relapsed during the 8 week follow-up period. No serious adverse reactions attributable to the drug were observed. Cefixime proved to be an effective oral drug in this open treatment trial and was associated with minimal side effects. It may provide a therapeutic alternative to the treatment of Salmonella infection with organisms multi-resistant to the standard drug regimens. Its oral formulation may provide an efficient alternative to parenteral therapy in less severely ill patients who can tolerate oral feeding.

Aztreonam compared to chloramphenicol in the treatment of enteric fevers.
Fifty-seven patients, twenty-six males and thirty-one females, aged 6 to 50 years (mean 12.6 years) with proven Salmonella typhi or S. paratyphi A septicaemia, were treated in an open randomized parallel study with either aztreonam or chloramphenicol. Aztreonam was given intramuscularly at a level of 50 to 80 mg/kg body weight per dose every 8 h for 7 days to thirty patients. Chloramphenicol was given orally in a dose of 50 to 70 mg/kg body weight every 6 h for 12 days to twenty-seven patients. All patients responded rapidly to treatment, becoming afebrile and asymptomatic within 5.5 to 6.4 days. Only one patient on aztreonam relapsed following treatment, whereas three patients relapsed after chloramphenicol treatment. There were no serious side effects with either drug.

A review of the treatment of bacterial meningitis.
This is review of our experience in the treatment of meningitis carried out at the Naval Medical Research Unit No. 3 (NAMRU-3), Cairo, Egypt since 1967. We have demonstrated that the serum and cerebrospinal fluid concentrations of ampicillin and its efficacy when used in the treatment of meningitis are comparable whether they are administered intravenously or intramuscularly. The third generation cephalosporin ceftriaxone was found to be very safe and effective when administered intramuscularly once a day in the treatment of the different types of acute bacterial meningitis. Aztreonam given intramuscularly was successful in the treatment of Gram-negative meningitis caused by multi-resistant organisms. The fatality rates and morbidity were significantly reduced in patients with meningitis when dexamethasone was given in conjunction with antibacterial chemotherapy.

Epidemiology, prevalence and clinical diagnosis of meningitis at Abbassia Fever Hospital, Cairo, 1966-1989.
The United States Naval Medical Research Unit No. 3 and the Abbassia Fever Hospital in Cairo, Egypt have together diagnosed and treated 7809 patients admitted to a meningitis ward since 1966. Aetiological diagnosis was based on clinical evaluation and laboratory studies. Marked increases in annual admissions in 1970-1972, 1980-1982 and 1987-1988 were related to increases in admissions due to meningococcal disease, while in 1977-1981 the increase was due to encephalitis related to Rift Valley fever. Better, rapid diagnostic procedures are needed to enable effective treatment to be given earlier and to reduce mortality rates.
