    Notes: Abstract Thirty HIV-infected children were cross-sectionally examined for morphologic hepatic abnormalities, using ultrasonography or histology. Abdominal ultrasonography was performed in 27 children. The liver structure was normal in four patients, one of whom had moderate symptoms of the HIV infection and three of them severe symptoms. Abnormal liver structure, compatible with hepatic steatosis, was found in 23 (85%) patients. Five of them were in an early stage of the HIV infection (category N or A), three patients were ranked in category B and 15 patients in category C. Histological examination of the liver was performed in 11 children and steatosis was documented in ten (91%). In seven (70%) of these ten children steatosis had been suspected by ultrasonography. In conclusion, steatosis is common in HIV-infected children. It is non-specific and has no impact on disease, diagnostic evaluation or management. Conclusion Ultrasonography is a sensitive, accurate, non-invasive screening tool. It is more reliable than liver function tests.

    Notes: Abstract It has been suggested that determination of the neutrophil elastase α1-proteinase inhibitor complex (E-α1PI) improves the diagnosis of bacterial infection in newborns. We evaluated the use of E-α1PI measurements in 143 newborns, consecutively admitted to a tertiary intensive care unit, employing a new random access assay and a sampling procedure that minimises post-collection artefacts. The 95% range for non-infected newborns was 20–110 μg/l up to the 5th day of life and 20–85 μg/l thereafter. The sensitivity as to the diagnosis of culture-proven bloodstream infection was 80% for E-α1PI, 86% for the immature to total neutrophil ratio, 64% for C-reactive protein and 37% for the total white blood cell count. The corresponding specificity amounted to 97%, 85%, 85% and 86%, respectively. E-α1PI increases preceded elevations of C-reactive protein by 18 h. Like C-reactive protein, E-α1PI levels did not distinguish between bloodstream infection and non-bacterial inflammatory responses. Results of E-α1PI became available within 1 h of collection and usually 2–3 h before manual leucocyte counts. Conclusion Determination of neutrophil elastase α1-proteinase inhibitor levels yields diagnostic advantages comparable to those of manual differential counts but provide faster turnaround times.

    Notes: Abstract Bartonella (Rochalimaea) henselae has been identified as causative agent of cat-scratch disease (CSD). Employing an indirect fluorescence antibody test we found that 20 (100%) out of 20 children with suspected CSD had serum titres toB. henselae of ≥512. By contrast, in all but one of the controls (n=332) including subjects exposed to the same cats, patients with diseases other than CSD, and blood donors the antibody titres were ≤256 (P〈0.001). However, significant regional differences in seroprevalence were noted. Conclusion Serology toB. henselae may supplant traditional criteria for the diagnosis of CSD and prevent patients from unnecessary surgery.

    Notes: Abstract An immunocompetent 9-year-old boy with disseminated catscratch disease involving spleen, cervical and abdominal lymph nodes, skull, and one clavicle is reported. Antibodies toRochalimaea quintana andR. henselae were detected, at increasing, then decreasing concentration. DNA extracted from the biopsied skull lesion was amplified by polymerase chain reaction and hybridized with species-specific oligonucleotides proving the presence ofR. henselae in affected tissue. Our findings suggest thatR. henselea plays a pathogenic role in cat-scratch disease.

    Notes: Abstract The diagnostic value of IgM to Bartonella henselae was evaluated in 20 children with cat-scratch disease (CSD) and controls consisting of 20 blood donors and 20 children with enlarged lymph nodes without CSD by two indirect immunofluorescence assays (IFA). One was based on B. henselae cocultivated with Vero cells (host cell-associated IFA), and the other on B. henselae grown on agar (host cell-free IFA). With the host cell-associated IFA, 18 of 20 children with CSD revealed IgM, whereas only 14 did so with the host cell-free IFA. Sera of two blood donors as well as sera from three children with enlarged lymph nodes without CSD showed also positive IgM to cell-associated B. henselae. This study reveals that the IFA applied had sensitivities of 70 – 90% and specificities of 87.5 – 100% for detecting IgM to B. henselae. Additionally, 20 patients with IgM to Epstein-Barr virus (EBV) capsid antigen were tested for IgM to B. henselae. Sera of 16 and 9 of these patients revealed IgM to B. henselae with the host cell-associated and the host cell-free IFA, respectively. Using Western blot these sera were demonstrated to react against linearized proteins of Vero cells and of B. henselae. Thus, since acute EBV infection may substantially reduce the specificity of B. henselae-specific IgM tests, we conclude that diagnosis of CSD should be confirmed by a significant IgG titer to B. henselae or by detection of this pathogen.
