Non-typhoid Salmonella septicemia and visceral leishmaniasis in a renal transplant patient.

BACKGROUND: We report on a renal transplant patient with recurrent attacks of fever, in which Salmonella septicemia as well as visceral leishmaniasis were diagnosed. PATIENT: The patient was a 62-year-old man with diabetic nephropathy and a living related kidney transplantation. RESULTS: Nearly 2 years after the transplantation, the patient developed recurrent attacks of fever, which were initially diagnosed as non-typhoid salmonellosis and improved after treatment. Three months later, he had relapses of fever. As the patient developed pancytopenia, a bone marrow aspiration was done, showing Leishmania parasites. The patient responded well to treatment with sodium stibogluconate. CONCLUSIONS: A high index of suspicion, together with better diagnostic assays to detect visceral leishmaniasis, is warranted in the diagnostic work-up of any fever of unknown origin in immunocompromised patients, especially in endemic areas.

Meropenem versus ceftazidime as empirical monotherapy in febrile neutropenia of paediatric patients with cancer.

This trial assessed the efficacy and safety of meropenem versus ceftazidime as empirical monotherapy for febrile neutropenia in paediatric cancer patients. In a prospective randomized study, 172 evaluable febrile episodes in the meropenem arm and 170 episodes in the ceftazidime arm were analysed for the clinical and microbiological response dependent on the kind of infection. About half the episodes were classified as fever of unknown origin (FUO) and the remainder as microbiologically or clinically documented infections. The most frequently documented infections in both arms were bacteraemias (22.1 versus 26.5%), predominantly caused by Gram-positive organisms (57.9 versus 71.1%). The success rate of the initial monotherapy differed significantly between the two arms and was 55.8% in the meropenem and 40.0% in the ceftazidime arm (P = 0.003). In addition, a significantly longer duration of fever and of antimicrobial therapy was observed in the ceftazidime arm than in the meropenem arm (median 5 versus 4 days, P = 0.022, and 7 versus 6 days, P = 0.009, respectively). With respect to the kind of infection, differences between the two arms were significant only in episodes classified as FUO but not in documented infections. In both arms, side effects were minimal. Despite the greater response rate for meropenem in FUO, the fact that ceftazidime has been proven to be as effective as meropenem in documented infections in the present study suggests that both drugs are useful as empirical monotherapy in febrile paediatric cancer patients.

[Serotype and antibiotic susceptibility of isolates from children with group A streptococcal infection; observation for 10 years].

Six hundred and seventy isolates from children with group A streptococcal infections from 1981 through 1990 were typed serologically and their antibiotic susceptibilities were determined. Productivity of streptococcal pyrogenic exotoxins was also investigated in some isolates. Four hundred and seventy-nine strains were isolated from patients with pharyngitis, 133 from those with scarlet fever, 35 from those with suppurative infection and 23 from those with non-suppurative disease. With immediate treatment (antibiotics were started at the same day throat swabs were taken) for 10 days, 5.3% of the patients with pharyngitis including scarlet fever had relapses and 13.4% of those patients had recurrences. Of the episodes of recurrences 15.7% were due to the same M serotype strains. Six patients had two episodes of scarlet fever. M type of isolate was different in the first and the second episode of each patient. Pyrogenic exotoxin type was unprecedented in the second episode of 4 out of 6 patients. M-typable and T-typable rates of isolates were 90.7% and 97.3%, respectively. Coincidence between M and T types was 73.3% (83.0% if including strains with the same and mixed T-type). Prevalent M-serotypes were 12 and 4, but M1, 3, or 28 was the most prevalent type of isolates in certain years. None of the 670 strains was resistant to penicillin G and cephalexin. Resistant rate of isolates to erythromycin and linecomycin was 26.5% in 1981 and 18.4% in 1982. But a marked decrease has noted since 1983 and only one has been resistant since 1986.(ABSTRACT TRUNCATED AT 250 WORDS)

[Hereditary intermittant fever].

UNLABELLED: Other than familial mediterranean fever: Four hereditary diseases presenting in the form of intermittent inflammatory flares are now recognized and have been characterised clinically and genetically. At the head of this group is Familial Mediterranean Fever (FMF), which affects thousands of patients originating from the Mediterranean area. However the familial Mediterranean Fever is no longer the only recurrent hereditary inflammatory disease. Three other entities have now been clearly defined: intermittent fever secondary to mutations in the type 1A Tumour Necrosis Factor receptor (TNF), of dominant autosomic genetic transmission, the hyperimmunoglobulinemia D syndrome and an entity regrouping the Muckle Wells syndrome, familial cold-induced urticaria, and the Chronic Infantile Neurological Cutaneous and Articular (CINCA) syndrome. IN PRACTICE: Because they require specific management and treatment, precise diagnosis of these entities is crucial.

The hemorrhagic fevers of Southern Africa with special reference to studies in the South African Institute for Medical Research.

In this review of studies on the hemorrhagic fevers of Southern Africa carried out in the South African Institute for Medical Research, attention has been called to occurrence of meningococcal septicemia in recruits to the mining industry and South African Army, to cases of staphylococcal and streptococcal septicemia with hemorrhagic manifestations, and to the occurrence of plague which, in its septicemic form, may cause a hemorrhagic state. "Onyalai," a bleeding disease in tropical Africa, often fatal, was related to profound thrombocytopenia possibly following administration of toxic witch doctor medicine. Spirochetal diseases, and rickettsial diseases in their severe forms, are often manifested with hemorrhagic complications. Of enterovirus infections, Coxsackie B viruses occasionally caused severe hepatitis associated with bleeding, especially in newborn babies. Cases of hemorrhagic fever presenting in February-March, 1975 are described. The first outbreak was due to Marburg virus disease and the second, which included seven fatal cases, was caused by Rift Valley fever virus. In recent cases of hemorrhagic fever a variety of infective organisms have been incriminated including bacterial infections, rickettsial diseases, and virus diseases, including Herpesvirus hominis; in one patient, the hemorrhagic state was related to rubella. A boy who died in a hemorrhagic state was found to have Congo fever; another patient who died of severe bleeding from the lungs was infected with Leptospira canicola, and two patients who developed a hemorrhagic state after a safari trip in Northern Botswana were infected with Trypanosoma rhodesiense. An illness manifested by high fever and melena developed in a young man after a visit to Zimbabwe; the patient was found to have both malaria and Marburg virus disease.

A passive hemagglutination test for diagnosis of trench fever due to Rochalimaea quintana.

A passive hemagglutination test devised for diagnosis of trench fever was easily performed and highly sensitive and specific. Tanned sheep erythrocytes were sensitized with soluble antigen from Rochalimaea quintana. The test detected antibody in six of seven cases of primary infection and in four cases of late, relapsed trench fever. Titers of antibody ranged from 1:20 to 1:640. Although both IgM and IgG antibody to R. quintana were detected by passive hemagglutination, IgG appeared to be the major reactive antibody. Antigens involved in the reaction were two types of proteins, one inactivated at 50 C and 60 C and the other at 80 C and 100 C. Of 322 control samples of sera that were tested, only one reacted positively; thus, the test had a specificity of greater than 99%. The single positive reaction was in serum from a patient with Q fever. This finding suggests that, in an area where Q fever is endemic, this disease must be ruled out in the interpretation of a positive passive hemagglutination test. Sera should be tested routinely against tanned, unsensitized erythrocytes, since an occassional sample of serum may agglutinate unsensitized cells. Because of its sensitivity and specificity, as well as its simplicity of performance, the passive hemagglutination test shows promise as a useful procedure for serologic identification of both acute and past infection with R. quintana.

Recurrent fever of unknown etiology: failure to demonstrate association between fever and plasma unconjugated etiocholanolone.

A sensitive method for determination of plasma unconjugated etiocholanolone by double-isotope-derivative dilution has been described. The mean values for normal subjects was 0.038+/-0.003 (SEM) mug/100 ml.40 patients, 20 with familial Mediterranean fever and 20 with other diseases characterized by recurrent fever were studied. The over-all mean concentration of plasma unconjugated etiocholanolone for the patients (febrile or afebrile) was 0.101 +/-0.012 mug/100 ml, significantly above that of normals. Mean plasma values for the patients while they were febrile did not differ from the mean values when they were afebrile. It is suggested that the concentration of plasma unconjugated etiocholanolone is not related to fever in these patients.
