    Résumé

    Background. - Children with malignant diseases are frequently given high dose chemotherapy plus autologous bone marrow transplants. Infectious complications can lead to morbidity and mortality in this type of treatment. This study was designed to determine whether immunoglobulin deficiency is an additional risk factor for infections. Patients and methods. - One hundred and twenty seven children with solid malignant tumors were treated between November 1987 and April 1992 in our Department by chemotherapy followed by autologous bone marrow transplantation. Their serum IgA, IgG and IgM concentrations were measured by nephelometry before chemotherapy, on the day of transplantation and every week thereafter. The frequency and severity of infectious episodes in all the children were recorded using a standard scale. The patients were divided into two subgroups, defined according to their serum IgG concentrations before the transplantation and 7 and 21 days later. Results. - Ig deficiency during transplantation was not associated with the occurrence of septicemia or focal infections. It was associated with the course of infection (P = 0.003) and with the occurrence of zoster virus infection during the first 6 months after transplantation (P = 0.003). Conclusions. - Immune replacement during bone marrow transplantation may be indicated in children at risk of Ig deficiency. Fifty percent of the children with solid tumors treated in our institution were at risk of this deficiency.
