Adding pharmacologically guided treatment intensification to dose adjustments by blood counts may not be warranted for girls, whereas new approaches to optimize maintenance therapy are needed for boys.
Physical pain and the moment of death are two important issues to address in end-of-life care of children with cancer in trying to reduce long-term distress in bereaved parents.
ABSTRACT. Objective. To evaluate viral vaccination immunity and booster responses in children treated successfully for acute lymphoblastic leukemia by chemotherapy and to study the response to treatment of antibody-producing plasma cells that are important for persistence of humoral immunity.Methods. Forty-three children who were in continuous first remission for a median of 5 years (range: 2-12 years) were studied. Before the leukemia was diagnosed, all children had been immunized against measles, mumps, and rubella according to the Swedish National immunization program. We analyzed levels of serum antibodies against measles and rubella by enzyme immunoassays. Avidity tests for measles antibodies were concomitantly performed by enzyme-linked immunosorbent assay for measles virus immunoglobulin G detection. The proportion of plasma cells in bone marrow was studied by flow cytometry at different times during treatment and follow-up. Children who lacked protective levels of antibodies to vaccination antigens were reimmunized. Serum was collected 3 months after immunization to assess vaccination responses.Results. After completion of the treatment, only 26 of the 43 children (60%) were found to be immune against measles and 31 (72%) against rubella. The proportion of bone marrow plasma cells decreased during treatment but returned to normal after 6 months. Revaccination caused both primary and secondary immune responses. Six of the 14 children without immunity failed to achieve protective levels of specific antibodies against measles and 3 against rubella.Conclusions. Our finding of loss of antibodies against measles and rubella in children treated with intensive chemotherapy suggests that reimmunization of these patients is necessary after completion of the treatment. To determine reimmunization schedules for children treated with chemotherapy, vaccination responses need to be studied further. A n increasing number of children survive leukemia as a result of improved and more intense chemotherapy. Other factors that influence outcome are improved supportive care including platelet transfusions, treatment with growth factors such as granulocyte colony-stimulating factor, and prophylactic antibiotic treatment. 1,2 Few studies have focused on potential long-term immunologic consequences of chemotherapy in survivors of childhood leukemia. Short-term (Ͻ2 years) effects of chemotherapy on immune function have previously been documented in children who were treated for malignancies, including acute lymphoblastic leukemia (ALL). 3,4 In those children, severe Band T-cell depletion results in clinical complications related to immune incompetence, 5,6 although the total B-and T-cell counts resolve quantitatively 6 months to 1 year after cessation of therapy. [7][8][9][10] In earlier studies, children who were treated with chemotherapy had lower levels of antibodies against common viral vaccination antigens such as measles, mumps, rubella, and polio. 11 The clinical implications, if any, of this finding are not completely und...
This qualitative study explores the caring situation of families with an immigrant background within the context of pediatric oncology care from the perspective of health care staff. Five focus group interviews and 5 complementary individual interviews were conducted after purposive and theoretical sampling, respectively. Grounded theory methodology revealed that obstacles to transcultural caring relationships are a main concern of the health care staff. These obstacles are divided into 4 main categories: linguistic, cultural and religious, social, and organizational. When health care staff fail to recognize obstacles to transcultural caring relationships, the result is inequity in care of families with an immigrant background. Equity in care for all does not mean identical treatment but, rather, care adjusted to the needs of the individual family regardless of background.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
