- Hepatocellular carcinoma and obliterated hepatic bile duct were found at postmortem examination in a 4-year-old girl with arteriohepatic dysplasia (Alagille's syndrome). AFP level was extremely high. Liver cirrhosis was present on percutaneous needle biopsy 9 months before she succumbed in progressive liver failure. Episodes of repeated gastrointestinal, life-threatening hemorrhages occurred during the last 6 months of her life. Histopathologic findings of the eyes were documented at autopsy.

- Concentrations of ara-CTP in leukemic cells isolated from CSF and of ara-C in lumbar CSF were measured following intraventricular ara-C administration in two girls with refractory meningeal leukemia. CSF samples were collected with a permanent intrathecal-lumbar catheter. In contrast to the comparatively short retention of ara-C in the CSF (t1/2 1.8 to 2.9 hours), there was a high accumulation and an extremely long retention of ara-CTP in the leukemic cells (t1/2 8.1 to 36 hours). The patients included in this study had an ara-C-resistant disease. No obvious relationship was seen between concentrations of ara-C in the CSF and of ara-CTP in the leukemic cells. Similar studies were performed after simultaneous intraventricular administration of hydrocortison and ara-C. Hydrocortison did not increase ara-CTP retention in the leukemic cells, nor did it effect CSF pleocytosis.

Diagnosis of invasive candidiasis in neutropenic children with cancer by determination of D-arabinitol/L-arabinitol ratios in urine
- 1997

In: Journal of Clinical Microbiology. - 1098-660X. ; 35:3, s. 636-640
-
Journal article (peer-reviewed)abstract
- Determination of D-arabinitol/L-arabinitol ratios (referred to as D/L-arabinitol ratios) in urine as a tool for the diagnosis of invasive candidiasis was investigated in a prospective study comprising 100 children with cancer. The analyses were made by gas chromatography. Positive D/L-arabinitol ratios were found for 10 of 10 children with confirmed invasive candidiasis, 12 of 23 patients undergoing empiric antifungal chemotherapy, and 4 of 67 children not receiving antifungal treatment. D/L-Arabinitol ratios were positive 3 to 31 days (median, 12 days) before the first culture-positive blood sample was drawn or empiric therapy was initiated. The regular monitoring of D/L-arabinitol ratios in urine holds great promise as a sensitive method for diagnosing invasive candidiasis in immunocompromised children with cancer. Moreover, it may be possible to use an early rise in D/L-arabinitol ratios as a basis for the institution of antifungal chemotherapy and as a means of avoiding unnecessary treatment with potentially toxic antifungal agents.

Platelet surface-bound IgG and platelet-specific IgG in plasma in childhood thrombocytopenia
- 1990
-
In: Acta Paediatrica Scandinavica. - : Wiley. - 0001-656X .- 0803-5253 .- 1651-2227. ; 79:3, s. 328-334

Journal article (peer-reviewed)abstract
- Quantification of platelet-bound immunoglobulin is widely used in the evaluation of thrombocytopenia. Several methods have been devised among which labelled ligand-binding assays seem to be most appropriate. In series of adult patients such assays have been shown to be superior in separating immune-thrombocytopenia from thrombocytopenia of non-immune causes. We studied 62 children with thrombocytopenia of various causes, using radiolabelled protein A as a ligand to measure platelet-surface bound IgG. The test was highly sensitive (93%) in detecting immune-thrombocytopenia. The specificity, however, was only 57%, which is less than in published studies of adults. In a number of cases presumed to be non-immune-thrombocytopenia, notably a few patients with leukaemia and bone marrow aplasia, we found increased amounts of platelet surface-bound IgG. The significance of this finding is not clear. An indirect assay measuring platelet-specific IgG in plasma was less sensitive (46%) but highly specific for immune-thrombocytopenia (89%). The measurements of platelet-surface-bound IgG and platelet-specific IgG in plasma are of limited diagnostic value in childhood thrombocytopenia but are useful in following the treatment in chronic ITP.
