[Clinical research on patients with typhoid and paratyphoid fever (1984-1987). Research Group for Infectious Enteric Diseases, Japan].

Patients with typhoid or paratyphoid fever, admitted to 14 hospitals for infectious diseases during 1984-1987, were epidemically and clinically studied. Of the total number of 183 typhoid, 49 paratyphoid fever patients, those infected overseas was 44.3% and 71.4% respectively, giving an overall annual decrease, yet marking an increased ratio of overseas infection. Patients aged 20s-30s and males were dominant. One hundred and seventy six cases (96.2%) of typhoid and all the paratyphoid fever cases were bacteriologically diagnosed. The period from the onset to the diagnosis was around 14 days in most cases, but beyond 29 days in over 10% of the cases. We would like to emphasize that enteric fever, focusing on high fever, bradycardia, roseola, hepatosplenomegaly, leukopenia, elevated serum-GOT GPT and LDH, can be easily diagnosed by blood/stool culture before beginning chemotherapy. Intestinal bleeding was recognized in 24 cases (13.1%) of typhoid and 4 (8.2%) of paratyphoid fever, intestinal perforation in 2 (1.1%) and death in 1 (0.5%) of typhoid fever. CP was most commonly used in chemotherapy. Bacteriological relapse was recognized in 7/127 cases (5.5%) of typhoid, 6/48 (13.0%) of paratyphoid fever those followed beyond 3 weeks, though eradication was attained by retreatment. One strain of S. typhi resistant to CP.ABPC.KM.SM was isolated in 1986 from a patient infected overseas. New quinolones seem reliable in our preliminary studies.

Typhoid: clinical picture and response to chloramphenicol. Prospective study in Bombay (1972).

The clinical picture of 78 cases with proven typhoid and 18 cases with proven paratyphoid A fever is presented. The diagnosis was made by isolating the organisms from the blood. The Widal test could not be used as a diagnostic criterion. By means of chemotherapy with chloramphenicol (initial dose 30-40 mg/kg body weight) defervescence was achieved within an average of 4.5 days. The course of the disease was generally mild; one patient with typhoid fever died. The average hospital stay was 19 days. Four patients of the typhoid fever group were readmitted with a relapse. The laboratory examinations included blood clot culture, phage typing, Widal test, haemoglobin, leucocyte count, transaminases, serum bilirubin, and routine examination and culture of stool and urine. Forty-two patients were infected with intestinal parasites and 25 with Shigella organism. The findings are discussed and compared with findings of similar studies of enteric fever.

Bilateral renal parenchymal malacoplakia presenting as fever of unknown origin: case report and review.

Malacoplakia is a rare inflammatory disorder seen most often in the urinary tract, where it is highly associated with coliform infection. Although first recognized by pathologists in 1902, it has received little attention from the infectious disease community. While there remains much uncertainty regarding the specific cause of malacoplakia, it appears to be associated with a defect in intracellular killing of ingested microorganisms by macrophages. We report a case of bilateral renal parenchymal malacoplakia that presented as fever of unknown origin, and we review 33 previously identified cases. Renal malacoplakia has traditionally been associated with high morbidity and mortality. More recently, treatment with antimicrobial agents such as trimethoprim or ciprofloxacin has yielded a better outcome than had been documented with other therapy. Malacoplakia should be considered in the evaluation of fever of unknown origin or of relapsing or refractory urinary tract infection. Therapy with antimicrobial agents capable of intracellular penetration is recommended.

[Aspects of typhoid fever in children].

Some aspects of typhoid fever in 77 children are discussed. There were 48 boys and 29 girls and their ages ranged from 1 month to 12 years. The patients were treated with chloramphenicol 100 mg/kg/d during the first 2 weeks and with either amoxycillin (100 mg/kg/d) or ampicillin (200 mg/kg/d) during the third week. The average duration of fever was 5.2 days. There was 1 relapse and 1 child, a baby aged 1 month, died. The correct diagnosis was not suspected by the referring doctor in 38% of the patients. On admission the commonest complaints were fever, abdominal pain, diarrhoea, headache and vomiting. The commonest findings on examination were tenderness or distension of the abdomen, apathy or delirium, rhonchi or crepitations, liver enlargement and meningism. There was anaemia (Hb less than 10 g/dl) in 23% and lymphopenia (less than 1500/microliter) in 43% of the patients. The differential white blood cell count revealed 5% or more unsegmented neutrophils in 32% of the patients, while 25% had 10% or more band cells. Two patients (sisters) failed to respond after 15 and 16 days of therapy with chloramphenicol and ampicillin because of resistant Salmonella typhi and were successfully treated with co-trimoxazole. Practitioners caring for black patients should always be on the alert for typhoid fever; some patients may not respond to chloramphenicol or amoxicillin. During the acute phase milk feeds are best replaced by soya products because of abdominal distension or aggravation of diarrhoea by milk.

Three-day treatment of typhoid fever with two different doses of ceftriaxone, compared to 14-day therapy with chloramphenicol: a randomized trial.

Fifty-nine adult Filipino patients suffering from typhoid fever documented by blood culture were randomly allocated to one of three different drug regimens. Nineteen patients received 3 g ceftriaxone iv once daily for three days. Twenty patients received 4 g ceftriaxone iv once daily for three days and 20 patients received oral chloramphenicol 3 g daily in divided doses for two days followed by 2 g daily for 12 days. Eighteen patients were cured (95%) with 3 g of ceftriaxone for three days. All patients receiving 4 g ceftriaxone per day for three days or chloramphenicol for 14 days were cured. In the ceftriaxone groups two patients developed typhoid fever 30 and 45 days respectively after completion of treatment and one further patient had evidence of reinfection. Three patients relapsed within 15 to 17 days in the chloramphenicol group. Fever subsided in most patients between six and eight days, with three patients having a prolonged and moderate fever for 11 days in the ceftriaxone groups. This study suggests that a short treatment of three days of typhoid fever with ceftriaxone (3 or 4 g once daily) is adequate and not hazardous as far as relapses are concerned.

[Successful use of etoposide in an elderly patient with chronic recurrent hemophagocytic syndrome].

A 66-year-old man was admitted to our hospital for fever on January 19, 1998. He began showing periodic high fever in June 1997 and an increased serum LDH in August 1997. His history included surgery for esophageal cancer in 1993. On admission, the patient's body temperature was 38.5 degrees C. Physical examination was negative for lymphadenopathy, hepatosplenomegaly, and skin rash. Peripheral blood revealed a hemoglobin level of 8.6 g/dl and a platelet count of 7.9 x 10(4)/microliter. Bone marrow examination showed hypocellularity with marked histiocytic hemophagocytosis. The various bacterial cultures were negative. Serum LDH was elevated to 1,606 IU/l, and ferritin was greater than 3,000 ng/ml. Antinuclear antibodies were negative. No significant elevation of viral antibody titers including that to Epstein-Barr virus was found. Hemophagocytic syndrome (HPS) was diagnosed, but no underlying diseases was identified. The patient's condition was complicated by interstitial pneumonia and pleural effusion. gamma-globulin and pulse methylprednisolone both proved ineffective for the HPS; however, complete remission was achieved with cyclic intravenous administration of etoposide (VP-16, 150 mg/day). Interestingly, the interstitial pneumonia resolved promptly with etoposide therapy. The patient relapsed, in July 2001, exhibiting high fever, cytopenia, and marrow hemophagocytosis. His condition was ameliorated by administration of etoposide. This was a rare case of chronic and recurrent HPS of unknown etiology accompanied by interstitial pneumonia. Etoposide should be considered as a primary therapy for HPS and its complications in cases such as our patients.

A clinical study of idiopathic eosinophilic pneumonia.

To better characterize idiopathic eosinophilic pneumonia (IEP), we studied the clinical and laboratory features of 27 patients. Patients with IEP could be divided into those with chronic eosinophilic pneumonia (CEP) (n = 14) and acute eosinophilic pneumonia (AEP) (n = 13). CEP was characterized by (1) multiple and dense areas of consolidation on chest radiographs and computed tomographic (CT) scans, (2) persistent symptoms, (3) a requirement for steroid therapy, and (4) possible relapses. On the other hand, AEP was characterized by (1) diffuse ground-glass and micronodular infiltrates on radiographs and CT scans (in mild cases, the lesions were sparse or localized), (2) acute onset with high fever, (3) spontaneous improvement, and (4) no relapse. In addition, peripheral blood eosinophil count was significantly higher in patients with CEP than in patients with AEP at the first examination. However, the eosinophil fraction also became markedly elevated during the subsequent courses of AEP. Analysis of bronchoalveolar lavage fluid revealed that the percentage of eosinophils was higher in patients with CEP than that in patients with AEP, whereas the percentage of lymphocytes was significantly greater in patients with AEP than patients with CEP. It was also noted that 75 percent of patients with CEP and 82 percent of patients with AEP had allergic diathesis, suggesting that both conditions are likely to occur in atopic individuals.

Relapsed and late-onset Nipah encephalitis.

An outbreak of infection with the Nipah virus, a novel paramyxovirus, occurred among pig farmers between September 1998 and June 1999 in Malaysia, involving 265 patients with 105 fatalities. This is a follow-up study 24 months after the outbreak. Twelve survivors (7.5%) of acute encephalitis had recurrent neurological disease (relapsed encephalitis). Of those who initially had acute nonencephalitic or asymptomatic infection, 10 patients (3.4%) had late-onset encephalitis. The mean interval between the first neurological episode and the time of initial infection was 8.4 months. Three patients had a second neurological episode. The onset of the relapsed or late-onset encephalitis was usually acute. Common clinical features were fever, headache, seizures, and focal neurological signs. Four of the 22 relapsed and late-onset encephalitis patients (18%) died. Magnetic resonance imaging typically showed patchy areas of confluent cortical lesions. Serial single-photon emission computed tomography showed the evolution of focal hyperperfusion to hypoperfusion in the corresponding areas. Necropsy of 2 patients showed changes of focal encephalitis with positive immunolocalization for Nipah virus antigens but no evidence of perivenous demyelination. We concluded that a unique relapsing and remitting encephalitis or late-onset encephalitis may result as a complication of persistent Nipah virus infection in the central nervous system.

Pleural and peritoneal leishmaniasis in an AIDS patient.

The case of an AIDS patient who developed pleuritis and peritonitis in the course of relapsing visceral leishmaniasis is reported. Visceral leishmaniasis, considered an opportunistic infection in patients infected with the human immunodeficiency virus (HIV) who live in endemic areas, has a chronic relapsing course. Typical manifestations such as fever, hepatosplenomegaly, lymphadenopathy, weight loss, or pancytopenia are not specific in advanced HIV infection. Atypical clinical presentations are becoming more frequent. This is believed to be the first report of peritoneal involvement by Leishmania in an AIDS patient.

Halofantrine efficacy in non-immune children with imported acute Plasmodium falciparum malaria Infection.

UNLABELLED: A rising incidence of imported acute malaria has been observed in non-immune traveller children returning from the tropics to France. Halofantrine efficacy has been poorly assessed in non-immune children. In order to assess halofantrine efficacy in non-immune children with acute uncomplicated Plasmodium falciparum malaria, we collected data of children with positive blood smears in an open prospective study. Children with neurological manifestations, vomiting and congenital long QT were excluded. All children were hospitalised and received halofantrine (24 mg/kg divided into three doses per day) on an empty stomach. Persistent fever after day 3 defined failure. Relapse was defined by a positive blood smear with or without systemic symptoms within a 1 month follow-up period. In total, 52 children were enrolled. No failure was observed, but relapses occurred in 14/52. On univariate analysis, the mean age of children with relapse was significantly lower (P<0.05). Moreover, diarrhoea was more frequently associated with relapses (P<0.04). Age and diarrhoea were significant independent factors contributing to relapses. CONCLUSION: This study shows that with a relapse rate of 27%, this regimen with a 1-day course of halofantrine is not to be recommended.

A relapsing inflammatory syndrome and active human herpesvirus 8 infection.

We describe an immunocompetent 61-year-old woman who was negative for human immunodeficiency virus and who had recurrent human herpesvirus 8 (HHV-8) infection associated with a relapsing systemic inflammatory syndrome characterized by fever, lymphadenopathy, splenomegaly, edema, arthrosynovitis, and rash. Kaposi's sarcoma developed 10 months after the initial clinical presentation. A correlation was documented between the recurrent clinical manifestations and the HHV-8 load in plasma and peripheral-blood mononuclear cells. Histologic examination of an enlarged lymph node heavily infected with HHV-8 revealed an atypical lymphoproliferative disorder characterized by paracortical hyperplasia and collapsed primary and secondary follicles.

Salmonella bacteraemia in a tertiary children's hospital.

A retrospective study was conducted between July 1990 and July 2002 to investigate the epidemiology, clinical characteristics, and the outcome of Salmonella bacteraemia in children. A total of 148 episodes of bacteraemia were identified in 144 children. The annual incidence ranged from 1.6 to 8.3 cases per 100,000 children < or = 14 y of age, and higher numbers of cases occurred in summer than in winter months. In 22 children the bacteraemia was caused by S. typhi and in 122 by S. non-typhi. S. enteritidis was the most common serotype isolated. Resistance to ampicillin was exhibited by 28.5% of Salmonella isolates, whereas all S. typhi isolates were susceptible to commonly used antibiotics. The mean age was 40.3 months (range 50 d to 14 y). Children with S. typhi bacteraemia were significantly older than children with S. non-typhi bacteraemia (7.8 vs 2.4 y, p < 0.01). 11 children were immunosuppressed. The immunosuppressed children had longer duration of fever, longer hospitalization stay, and higher relapse rates compared to normal children (p < 0.05). Four children developed complications and 1 died. Although the incidence of S. typhi bacteraemia is decreasing, the non-typhi species continue to cause significant morbidity in our geographical region.

Amphotericin B treatment of fungemia due to unusual pathogens in neutropenic patients: report of two cases.

Invasive fungal infections occur frequently in neutropenic patients although only in recent years has the role of emerging fungi been clearly established. We describe two cases of fungemia caused by Trichosporon beigelii and Rhodotorula glutinis respectively in two neutropenic patients with hematological malignancies who were treated with amphotericin B. The first patient, with refractory multiple myeloma, died following massive pneumonia despite therapy with amphotericin B and granulocyte-colony stimulating factor (G-CSF); the second patient, with relapsed acute lymphatic leukemia and persistent fever without any other clinical evidence, finally recovered. Amphotericin B continues to be considered the "gold standard" in the treatment of invasive mycoses although other approaches need to be tested for refractory infections.

Treatment of vancomycin-resistant enterococcus with quinupristin/dalfopristin and high-dose ampicillin.

OBJECTIVE: To report the successful treatment of vancomycin-resistant Enterococcus (VRE) bacteremia using the combination of quinupristin/dalfopristin and high-dose ampicillin. CASE SUMMARY: A 38-year-old African American woman with relapsed acute myeloid leukemia and neutropenic fever developed VRE bacteremia following 3 successive courses of vancomycin for methicillin-resistant staphylococcal infections. Treatment with linezolid was initiated; however, after 9 days of therapy, blood cultures continued to reveal VRE and the patient became febrile. The patient was subsequently switched to quinupristin/dalfopristin and high-dose ampicillin. The fever resolved and all subsequent blood cultures were negative after the initiation of combination therapy. DISCUSSION: The emergence of VRE infections presents a treatment challenge in immunocompromised patients. When treating VRE infections in this patient population, the effectiveness of linezolid and quinupristin/dalfopristin is limited by their bacteriostatic activity when used as monotherapy. Recent in vitro data suggest synergistic activity with quinupristin/dalfopristin when used in combination with other antimicrobials in selected isolates of VRE. CONCLUSIONS: Persistent VRE bacteremia was successfully treated in this neutropenic patient using the combination of high-dose ampicillin and quinupristin/dalfopristin. Case reports and in vitro data suggest that concomitant therapy with high-dose ampicillin may be an effective treatment alternative for VRE infections not responding to standard therapy.

Sweet's syndrome associated with granulocyte colony-stimulating factor.

We present two patients who developed Sweet's syndrome (SS) during recombinant granulocyte colony-stimulating factor (G-CSF) treatment. Case 1 : on day 11 of the fifth cycle of G-CSF treatment, a 21-year-old man with relapsed, intracranial germ cell tumor had fever, and painful, subcutaneous nodules on his right arm and right leg concomitant with neutrophilia. Skin biopsy revealed neutrophilic panniculitis. The skin lesions disappeared completely after discontinuance of G-CSF. Case 2 : on day 7 of G-CSF treatment, a 50-year-old woman with small cell lung cancer developed fever, and widely disseminated pruritic erythema on her trunk and extremities. The histopathology of the skin was compatible with SS. Her skin lesions also disappeared after discontinuance of G-CSF treatment. She subsequently received three cycles of additional G-CSF treatments without recurrence of SS. It is possible that G-CSF treatment accidentally induced or augmented the proliferation and differentiation of clonal neutrophils with abnormal functions, since in the cases presented SS developed only once in spite of several treatments with G-CSF.

Retinoic acid syndrome induced by arsenic trioxide in treating recurrent all-trans retinoic acid resistant acute promyelocytic leukemia.

Arsenic Trioxide (As2O3) is an effective agent for treating acute promyelocytic leukemia achieving a complete remission rate of about 60% to 90%. It is similar to all-trans retinoic acid (ATRA) when treating acute promyelocytic leukemia (APL), because both agents have limited side effects compared to conventional chemotherapy, although the treatment period is more prolonged. During treatment, both agents may induce leukocytosis, and in patients taking ATRA, leukocytosis appears to be related to the development of retinoic acid syndrome (RAS). We report here a case of APL treated with ATRA in combination with chemotherapy 3 years earlier. During treatment, an episode of RAS with fever, edema, pericardiac effusion etc. was encountered. Recently, she had a relapse of leukemia, and As2O3 therapy was used. Leukocytosis developed again, and symptoms of fever, skin rash, edema resembling a RAS also developed, which was quickly relieved by steroid administration in a manner resembling response to RAS.
