- The expression of lymphocyte surface markers as well as the production of interleukin-2 (IL-2) and interferon-gamma (IFN) by mitogen-stimulated peripheral blood mononuclear cells (MNC) have been studied in five children with constitutional aplastic anemia. A significantly reduced T4/T8 ratio was found and two of five patients also had a reduced percentage of B cells. One patient had a high percentage of HLA-DR positive T8+ cells, very suggestive of a high degree of circulating activated T suppressor/cytotoxic cells. IL-2 production was reduced in two patients, whereas IFN production was only reduced in one of these. The abnormalities found correlate with the duration of the bone marrow failure. The patients with the longest duration of bone marrow failure also exhibited the lowest T4/T8 ratio. No spontaneous IFN production was detected in any of the patients. There was no clinical benefit or reversal of the immune abnormalities during and following treatment with cimetidine and cyclosporine A in two patients.

Arterial occlusion due to Listeria meningoencephalitis in an immunocompromised boy
- 1987

- Sequential CAT scan studies of the brain were performed in a 7-year-old boy with Listeria monocytogenes serotype 1 meningoencephalitis. The infection occurred while he was receiving maintenance chemotherapy for T-cell non-Hodgkin lymphoma. A lesion in the right hemisphere during the infection resulted in an excessive enlargement of the right ventricle 10 months later, most probably caused by arterial occlusion.

Fulminating clostridial septicemia in children treated for lymphoproliferative disorders
- 1984
-
Ingår i: Scandinavian Journal of Infectious Diseases. - 1651-1980. ; 16:2, s. 157-159

Tidskriftsartikel (refereegranskat)abstract
- Overwhelming Clostridium septicum infection in 2 children, 1 and 4 yr old, with acute lymphoblastic leukemia and B-cell non-Hodgkin malignant lymphoma, respectively, as well as fatal C. perfringens infection in a 3-yr-old child with histiocytosis-X are reported. A neutropenic patient with fever, abdominal symptoms and hypotension--but otherwise being well--must be suspected of having clostridial disease. The most alarming feature is shock and rapid course.

A new specific chromosomal rearrangement, t(8;16) (p11;p13), in acute monocytic leukaemia
- 1987
-
Ingår i: British Journal of Haematology. - 0007-1048. ; 66:3, s. 323-326
-
Tidskriftsartikel (refereegranskat)abstract
- The translocation t(8;16) (p11;p13) was found as the sole deviation from the normal karyotype in three patients with acute monocytic leukaemia. The bone marrow morphology was strikingly similar in the two cases where smears were available for re-evaluation: the leukaemic cells showed signs of differentiation, and active erythrophagocytosis was a particularly conspicuous feature. We suggest that t(8;16) (p11;p13) represents a new consistent abnormality in acute monocytic leukaemia, specifically associated with the differentiated subtype (M5b) and with pronounced phagocytic activity by the leukaemic monocytes.

High resolution banding analysis of the reciprocal translocation t(6;9) in acute nonlymphocytic leukemia
- 1986
-
Ingår i: Cancer Genetics and Cytogenetics. - 0165-4608. ; 22:3, s. 195-201
-
Tidskriftsartikel (refereegranskat)abstract
- The cytogenetic, hematologic, and clinical characteristics of a 13-year-old girl with acquired t(6;9)(p23;q34) and dysmyelopoietic syndrome developing into acute myelomonocytic leukemia are described, bringing the total number of patients with t(6;9) and hematologic disease described in the literature up to 19. The diagnosis has been acute myeloid leukemia in the great majority of these patients; only four have had acute myelomonocytic leukemia. High resolution analysis at the 550 band stage localized the breakpoints in chromosomes #6 and #9 to p23 and 9q34.3, respectively. Previous investigations employing high resolution cytogenetics have mapped the typical 9q breakage site in chronic myeloid leukemia to 9q34.1. In situ hybridization studies have demonstrated that the cellular oncogene c-abl remains on the derivative 9q+ chromosome in t(6;9), whereas it is moved to the Ph marker in t(9;22). Thus, the combined data indicate that c-abl is located between 9q34.1 and 9q34.3, i.e., in subband 9q34.2 or its immediate vicinity.

Reciprocal translocation (11;19)(q23;p13) in congenital acute lymphoblastic leukemia
- 1986
-
Ingår i: Cancer Genetics and Cytogenetics. - : Elsevier BV. - 0165-4608. ; 23:3, s. 239-244
-
Tidskriftsartikel (refereegranskat)abstract
- The cytogenetic, clinical, and immunologic findings ina 4-month-old girl with acute lymphoblastic leukemia (ALL) are reported. The malignant lymphoblasts were characterized cytogenetically by the reciprocal translocation t(11;19)(q23;p13); immunologically by an immature pre-B-ALL phenotype. In spite of the high-risk nature of the leukemia, the patient attained complete remission relatively quickly and is still free of disease 3 years after diagnosis. Because the only two previously reported ALL patients with t(11;19) also seem to have responded well to therapy, this cytogenetic abnormality might turn out to be an indicator of favorable prognosis in ALL.

Blunted pubertal growth after leukemia: a new pattern of growth hormone insufficiency
- 1988
-
Ingår i: Hormone Research. - 0301-0163. ; 30:2-3, s. 68-71
-
Tidskriftsartikel (refereegranskat)abstract
- Growth, age at menarche and spontaneous GH secretion were studied in girls after treatment for acute lymphoblastic leukemia (ALL). These girls had normal prepubertal growth but subnormal pubertal growth. Mean final height was 1 SD less than expected before puberty. The average age at menarche was significantly lower than the normal mean for Swedish girls. The mean 24-hour GH secretion was severely blunted and there was no increase during puberty. We suggest that girls treated for ALL, including CNS irradiation, have a relative GH insufficiency which becomes clinically obvious only when the girls cannot respond to the increased demands for GH in puberty.

Disturbed pubertal growth in girls treated for acute lymphoblastic leukemia
- 1987

Tidskriftsartikel (refereegranskat)abstract
- Pubertal growth was studied in 10 girls previously treated for acute lymphoblastic leukemia. The average age at menarche was 12.2 years, which is significantly lower (p less than 0.01) than the expected 13.1 years. Compared with normal girls, these girls showed a subnormal (p less than 0.05) peak height velocity during the second year before menarche. The remaining growth before menarche as well as the total postmenarchal growth was close to the normal average. The average final standing height was 1 SD less than what would be expected from their height 1 year after the cessation of therapy. A relative growth hormone deficiency in combination with early onset of puberty could account for this loss in final height.
