Case Reports. Chronic and acute Aspergillus meningitis.

Cerebral aspergillosis usually occurs in severely immunocompromized hosts, is difficult to diagnose, and has a poor prognosis. After 14 months of chronic meningitis, ventriculitis, choroid plexitis, and lumbar arachnoiditis, which was complicated by acute hydrocephalus, Aspergillus, suspected to be from the candidus group, was isolated from the cerebrospinal fluid (CSF) of a previously healthy man. Thereafter Aspergillus antigen was found in stored plasma and CSF samples. He was treated with voriconazole and itraconazole. In a haemodialysis patient affected by an acute meningococcal meningitis, following a 3-day symptom-free interval, symptoms and signs of acute meningitis had reappeared and were unresponsive to a broad antimicrobial coverage. However, they resolved within 5 days after liposomal amphotericin B treatment had been started. From his CSF Aspergillus-DNA was identified and Aspergillus fumigatus isolated by culture. These two different clinical cases show that Aspergillus-DNA and antigen detection tests represent an advance in the diagnosis and liposomal amphotericin B, voriconazole, and itraconazole are an advance in the treatment of Aspergillus meningitis.

Temporal arteritis associated with Chlamydia pneumoniae DNA detected in an artery specimen.

Temporal arteritis is a clinical manifestation of giant cell arteritis. The etiology of this disease is still unknown. Sudden onset and wide variations of incidence are reported in different parts of the world. Acute onset is often associated with flu-like symptoms, indicating that infectious factors probably act as precipitating agents. We describe a 72-year-old man referred to our department in January 1999 for unremitting fever and temporal arteritis associated with Chlamydia pneumoniae infection.

Exchange blood transfusion in severe falciparum malaria: retrospective evaluation of 61 patients treated with, compared to 63 patients treated without, exchange transfusion.

The rationale for exchange blood transfusion (ET) in severe falciparum malaria is threefold: reduction of parasitaemia, reduction of presumptive 'toxic' factors, and improvement of the rheological quality of the blood. We evaluated the records of 61 patients treated with ET to describe the present status of malaria treatment in Germany, Austria and Switzerland and to assess the efficacy of ET. Clinical data of 61 patients treated with ET were compared to data of 63 patients treated in 2 hospitals where ETs were generally not performed. We found that exchange transfusion is applied according to the clinician's subjective impression rather than strict guidelines. Logistic regression analysis adjusting for the differences in clinical parameters between patients treated with or without ET did not identify treatment as a prognostic indicator (odds ratio for relative risk of death with ET: 1.3; 95% CI: 0.4-4.9). Exchange transfusion did not significantly improve the unfavourable prognosis in cases of severe falciparum malaria. However, failure to reach statistical significance may be due to the retrospective design of the study and therefore non-systematic approach.

[Cat scratch disease. Bartonella henselae antibodies and DNA detection in regional lymphadenopathy]. / Katzenkratzkrankheit. Bartonella-henselae-Antikörper und Nukleinsäurenachweis bei regionaler Lymphadenopathie.

HISTORY AND CLINICAL FINDINGS: Two hard, pressure-sensitive nodules developed in the lower jaw of a 22-year-old woman. After a dental cause had been excluded, she was treated for suspected tonsillitis with Ceftibuten. Erythrocyte sedimentation rate was increased to 18 mm in the first hour. There were no other significant biochemical findings and fine-needle biopsy of one of the nodules showed nonspecific inflammatory reaction. INVESTIGATIONS: Sonography revealed two lymph nodes, 7 and 22 mm in diameter. Suspected cat scratch disease was confirmed by immunofluorescence with Bartonella (Rochalimaea) henselae and quintana antigens. TREATMENT AND COURSE: After a course of Clarithromycin (250 mg twice daily) for 6 weeks the lymph nodes had shrunk and the overlying skin was thin and discoloured brown. One node was incised and drained and the material examined. Microbiology was negative, but DNA sequencing confirmed Bartonella henselae. As a consequence, Rifampicin was given for 2 months (600 mg daily). Wound healing was very slow and the scar had regressed little after 9 months.

Severe pneumonia in pregnancy three months after resolution of cutaneous zoster.

A 22 weeks pregnant women was affected by a life-threatening pneumonia and a paresis of the proximal muscles with cerebrospinal fluid pleocytosis. Her past medical history had been unremarkable except for recurrent episodes of paraumbilical herpes zoster. The clinical findings suggested a dissemination of varicella-zoster virus without skin lesions. Acyclovir was added to the therapy, and the clinical picture began to improve. Varicella-zoster virus DNA was detected in placental tissue by DNA-hybridisation analysis.
