The rapid slide agglutination test in the diagnosis of typhoid fevers and typhus.

Of 10,000 sera examined for infectious diseases by both the rapid slide agglutination and the tube agglutination tests, 128 were found positive for typhus fever and 257 for typhoid and paratyphoid infections. Of 84 of the last mentioned cases of typhoid and paratyphoid, which were confirmed by cultural examination, 45 (53.5%) were negative to the tube test, whereas only one (1.2%) was negative to the slide test. Taking the total of 385 cases in which the clinical picture was typical and either one of the two serological tests positive, the tube test was negative in 183 cases (47.2%) whereas the slide test was negative once only (0.3%). Of 201 cases in which both the slide and tube tests were positive, the slide test gave the result, on an average, six days earlier in 19 cases (10%).A control test of 139 sera from patients suffering from various other diseases gave a negative result on the slide test.

Comparison of the Vi indirect fluorescent antibody test with the Widal agglutination method in the serodiagnosis of typhoid fever.

The indirect fluorescent antibody test using a whole Salmonella typhi Vi suspension as the antigen has been evaluated for the diagnosis of typhoid fever. Results using sera from 140 patients with S typhi infections proved on culture show the test to have good sensitivity. The test appears to be highly specific, although it has not yet been investigated with respect to typhoid vaccination or in the context of infections due to salmonellas other than S typhi.

Standardisation of polymerase chain reaction for the detection of Salmonella typhi in typhoid fever.

To improve the diagnosis of Salmonella typhi infection, a polymerase chain reaction (PCR) assay was developed for the amplification of the dH flagellin gene of S typhi. Primers were designed from dH flagellin gene sequence which will give an amplification product of 486 base pairs. In tests to study the specificity of the assay, no amplification was seen in non-salmonella strains or salmonella strains with flagellar gene other than "d". Sensitivity tests determined that 28 pg of S typhi target DNA or 3 x 10(2) target bacteria could be detected by the PCR assay. Subsequently, the PCR technique was used for detection of S typhi in blood or clot cultures from 84 patients clinically suspected of having typhoid fever, and from 20 healthy control subjects. Twenty five of 84 samples from clinically suspected cases were positive by PCR; four of which were culture negative. No amplification was seen in samples from patients who were culture positive for organisms other than S typhi or from controls. The time taken for each sample for PCR analysis was less than 48 hours compared with three to five days for blood or clot culture. PCR appeared to be a promising diagnostic test for typhoid fever.

Perforated typhoid enteritis in children.

A prospective study of 65 patients with perforated typhoid enteritis managed operatively over a 3 year period at a university hospital is presented. There were 45 males and 20 females with ages ranging from 5 to 15 years. Presenting symptoms were fever, abdominal pain, vomiting and either diarrhoea or constipation. All the patients were subjected to surgery and 56 (86%) underwent two-layer bowel closure after freshening of ulcer margins. The overall mortality rate in this study was 20% and was adversely influenced by the increasing duration of perforation, presence of shock and faecal peritonitis. Early surgery after prompt and adequate resuscitation is life saving. However, prevention of typhoid fever by providing safe drinking water and better sanitary conditions appears to offer the best chance of decreasing the high rates of mortality and morbidity of this deadly disease.

Post-typhoid anhidrosis: a clinical curiosity.

A 19-year-old girl developed generalised anhidrosis following typhoid fever. Elaborate investigations disclosed nothing abnormal. A skin biopsy revealed the presence of atrophic as well as normal eccrine glands. This appears to be the third case of its kind in the English literature. It is postulated that typhoid fever might have damaged the efferent pathway of sweating.

Pseudotumor cerebri complicating typhoid fever.

The case of a 22-year-old patient is described, who developed a clinical picture of pseudotumor cerebri in the course of typhoid fever, an association not previously described. The patient progressed favorably after treatment with amoxicillin. The etiopathogenesis of pseudotumor cerebri is briefly discussed, as is the need to study the possible existence of this disorder in cases of typhoid fever patients with headaches and/or visual deficits which are not readily explained.

Treatment of typhoid fever with fosfomycin alone and associated to chloramphenicol or ampicillin.

Treatment with fosfomycin alone and associated to subtherapeutic doses of chloramphenicol or of ampicillin, has been tried on 50 patients with typhoid fever and on four carriers of S. typhi in the Hospital del Rey. 15 patients were treated with fosfomycin alone, 22 with fosfomycin plus chloramphenicol and 13 with fosfomycin plus ampicillin. The treatment lasted 15-20 days. The results have been evaluated clinically and bacteriologically, haemo- and coprocultures being carried out. The sensitivity of the isolated germs has been studied, including MIC and the synergism in vitro between fosfomycin-chloramphenicol and fosfomycin-ampicillin. Fosfomycin, chloramphenicol and ampicillin determinations have been carried out on the blood. The cures obtained were 67, 82 and 92% respectively with fosfomycin, fosfomycin-chloramphenicol and fosfomycin-ampicillin. We believe that this antibiotic can be useful in the treatment of typhoid fever, associating it to chloramphenicol or ampicillin, due to the synergism existing between them and given the results we have obtained.

Effect of a new sulfa-trimethoprim combination (trimethoprim-sulfamethopyrazine) in typhoid fever. A double-blind study on 72 adult patients.

A double-blind study on 72 adult patients affected by typhoid fever was done utilizing a new sulfa-trimethoprim combination (trimethoprim-sulfamethopyrazine) versus the well-known combination trimethoprim-sulfamethoxazole. The dosage used for the new drug was 2 capsules (250 mg trimethoprim + 200 mg sulfamethopyrazine per capsule) the 1st day and 1 capsule for the following 14 days or 2 capsules (trimethoprim 80 mg + sulfamethoxazole 400 mg per capsule) twice daily for 15 days. Both drugs proved to be very effective according to the parameters considered. No complications (intestinal bleeding, perforation, etc.) occurred in any of the patients, and untoward effects were not observed. It is therefore our opinion that treatment of typhoid fever with a sulfa-trimethoprim combination is both effective and safe.

Cefoperazone compared with chloramphenicol in the treatment of typhoid fever.

The authors have conducted an open randomized study to compare the clinical efficacy and safety of cefoperazone with those of chloramphenicol in the treatment of typhoid fever. They studied 56 subjects (28 in each group), 36 males and 20 females, whose average age was 25.9 years. The diagnosis of typhoid fever was made when one of the at least three blood cultures performed was positive for Salmonella typhi and in the presence of a 'toxic'-like symptomatology and hyperpyrexia (39 degrees C). Moreover, several stool cultures were done and the signs and symptoms characteristic of the pathology in progress were monitored. Furthermore, the MICs of cefoperazone and chloramphenicol were determined for all the strains of S. typhi isolated in both groups. Cefoperazone was given at the mean dose of 2 g i.v. every 8 h, and chloramphenicol at the dose of 500 mg by oral route every 6 h. The results obtained were assessed statistically (Friedman's test and Fischer's test). The authors conclude that cefoperazone is as active as chloramphenicol, and the importance of this result should not be underestimated.

Cardiac status in typhoid fever.

Fifty adult patients with culture-proved typhoid fever were subjected to daily clinical, electrocardiographic (ECG), and electrolyte assessment to evaluate and correlate their cardiac status. Transaminases and creatine kinase (CCK-MB) were estimated on alternate days and echocardiographic assessment was done once during hospitalization. The patients were distributed into groups: I (21) who did not have any ECG or enzymes changes, IIa (17) who had both ECG as well as enzymes changes, IIb (5) who had ECG changes only, and IIc (7) who had elevated enzymes only. Various types of ECG abnormalities were observed in 22 patients. Transaminases were significantly raised (P < 0.001) in group IIa and IIc patients (24). However, CK-MB was significantly raised (P < 0.001) only in the 5 patients of group IIa. There was no relationship among the elevated enzyme levels, severity of disease, and ECG changes. Further, ECG changes were observed during the convalescence stage also, but transaminases were found to be elevated only during the acute stage. It is concluded that definite injury to the heart occurs during typhoid fever. However, it is difficult to ascertain the exact time and extent of the injury. Further, CK-MB was not found to be superior to transaminases for assessment.

The value of C-reactive protein in the diagnosis of intestinal perforation in typhoid fever.

Serum C-reactive protein concentrations were measured in 28 Nigerian patients with typhoid fever on presentation at hospital and at intervals thereafter. Five of the 28 (18%) were subsequently diagnosed as suffering from ileal perforation. These patients had concentrations of C-reactive protein during the first 24 h of admission which were significantly higher (mean = 229 mg/L) than those without perforation (mean = 91 mg/L). C-reactive protein may have a role in the prediction of early diagnosis of perforation in patients with typhoid fever.

Management of bowel perforation in typhoid fever.

The best survival rates after ileal perforation in typhoid fever are to be found in patients undergoing operation within 24 h. Conservative management of typhoid perforation, which was widely advocated after the introduction of chloramphenicol, appears to be associated with a substantially increased mortality compared to surgery, although randomized comparisons have never been conducted. Clinical, radiological and ultrasound examination assist in the diagnosis of perforation. After vigorous resuscitation, simple surgical closure of the perforation and abdominal irrigation will suffice for most cases. Antibiotics effective against S. typhi, coliforms and anaerobes are required.

Haematological profile in typhoid fever.

The haematological profile in 20 culture proven patients with typhoid fever of varying age and of both sexes was studied. Significant changes observed were anaemia, leucopenia, eosinopenia, thrombocytopenia and sub-clinical disseminated intravascular coagulation. The bone marrow of typhoid patients showed myeloid maturation arrest, decrease in the number of erythroblasts and megakaryocytes with increased phagocytic activity of histiocytes.

Comparative clinical trial of amoxycillin and chloramphenicol in the treatment of typhoid in adults.

A randomized clinical trial in sixty-two adult patients suffering from typhoid fever, proved by blood and marrow culture, showed that amoxycillin in a dosage schedule of 1 g 8-hourly orally for fourteen days was better than chloramphenicol with regard to clinical and temperature response and in respect of carriers and relapse rates. One patient developed a hypersensitivity reaction to amoxycillin which cleared on withdrawal of the drug. Success was achieved in 90% of cases. These findings lend very strong support to the value of amoxycillin as a superior alternative to chloramphenicol in the treatment of typhoid fever.

Comparative trial of short-course ofloxacin for uncomplicated typhoid fever in Vietnamese children.

An open, randomised comparison of 2 or 3 days of oral ofloxacin (10 mg/kg/day) for uncomplicated typhoid fever was conducted in 235 Vietnamese children. Multi-drug-resistant Salmonella typhi was isolated from 182/202 (90%) children and 5/166 (3%) tested isolates were nalidixic acid-resistant (Na(R)). Eighty-nine of 116 children randomised to 2 days and 107/119 randomised to 3 days were blood culture-positive and eligible for analysis. There were 12 (13.5%) failures in the 2-day group (six clinical failures, four blood culture-positive post treatment, two relapses) compared with eight (7.5%) failures in the 3-day group (four clinical failures, one blood culture-positive post treatment, three relapses) (OR 1.9, 95% CI 0.7-5.5,p = 0.17). There were no significant differences in the mean (95% confidence interval) fever clearance times (h) [92 (82-102) vs 101 (93-110), p = 0.18] or duration of hospitalisation (d) [7.6 (7.2-8.1) vs 8.0 (7.6-8.4), p = 0.19] between the two groups. There was one failure in the four eligible children infected with an Na(R) isolate of S. typhi. No adverse events were attributable to the ofloxacin. These results extend previous observations on the efficacy of short courses of ofloxacin for children with uncomplicated multi-drug-resistant typhoid fever.

Prevalence of multi-drug resistant Salmonella typhi among clinically diagnosed typhoid fever patients in Lagos, Nigeria.

A total of 635 clinically diagnosed typhoid fever patients were bled from three different health institutions in the metropolis of Lagos, Nigeria over a period of 15 months, May 1997 to July 1998. Out of the total blood cultured, 101 (15.9%) isolates of Salmonella species were isolated of which 68 (67.3%) were S. typhi, 17 (16.8%) and 16 (15.8%) were S. paratyphi A. and S. arizonae respectively. The overall isolation rate of S. typhi among patients is 10.7%, with most isolates 45.9% found among the severely-ill young adults, age group 16-30 years. All isolates were subjected to anti-microbial susceptibility testing using 12 different antibiotics: chloramphenicol, ampicillin, cotrimoxazole, gentamicin, colistin sulfate, nalidixic acid, nitrofurantoin, cefotaxime, tetracycline, streptomycin, ofloxacin and ciprofloxacin. All the S. typhi and S. paratyphi A isolates showed resistance to two or more of the 10 of 12 antibiotics tested particularly the 3-first-line antibiotics commonly used (chloramphenicol, ampicillin and cotrimoxazole) in the treatment of typhoid fever in Nigeria. No isolate showed resistance to ofloxacin and ciprofloxacin, however, nalidixic acid and gentamicin showed a moderate and appreciable inhibition to most of our isolates.
