The incidence of malignant tumors in the primary immunodeficiency diseases is dramatically increased. Four patients with primary immunodeficiencies who developed fatal malignancies are reported. Lymphoreticular tumors and leukemia predominate in most conditions, but epithelial neoplasms are the most common tumors in selective Iga deficiency, and they comprise over one-fourth of malignancies in common variable immunodeficiency. With the exception of common variable immunodeficiency and the Wiskott-Aldrich syndrome, hyperplasia of lymphoid tissue usually does not occur. Lymph node enlargement in any of the other immunodeficiencies is therefore most likely secondary to malignancy. Benign gastrointestinal nodular lymphoid hyperplasia occurs frequently in common variable immunodeficiency and in some instances may be impossible to differentiate roentgenologically from lymphoma.

We have used lymphocyte stimulation in vitro to characterize the degree of cell-mediated immunodeficiency in different patients. The effect of treatment of patients with immunodeficiencies is illustrated by lymphocyte transformation in vitro before, during and after therapy (eg bone marrow transplantation of severe combined immunodeficiency and transfer factor treatment in Wiskott-Aldrich syndrome). The mixed lymphocyte culture test has been used for selection of bone marrow transplant donor for a patient with CID when an HL-A identical sib was not available. The results of the transplantation in this patient with graft from a donor who differed from the patient in respect of both HL-A haplotypes (but MLC identical with the patient) is reported. The MLC data on another family with 2 children with Nezelof disease are reported. The data indicate that one of the patients could be a chimera after intrauterine grafting of maternal immunocompetent cells.

Results of therapeutic trials of transfer factor in a number of laboratories suggest clinical benefit and enhancement of immunological reactivity in patients with primary or secondary immunodeficiency diseases. Long term follow-up of 32 patients with the Wiskott-Aldrich syndrome suggested that transfer factor caused conversion of immunologic reactivity, apparent clinical benefit, and prolonged survival in some, but not in all patients. In 18 patients with disseminated (Stage III) malignant melanoma treated with surgery and transfer factor, survival was better than would ordinarily be expected for disseminated disease (78% with mean follow-up of 2 years). A randomized trial has been initiated which will answer the question of the efficacy of transfer factor as surgical adjuvant therapy in malignant melanoma. Studies in human subjects suggested that transfer factor does not cause enhancement of reactivity in normal subjects, when evaluated in a controlled, double-blind fashion. Similar controlled studies in immunodeficient patients are necessary to ascertain whether transfer factor does cause enhancement of immune responses in these patients. Based on these observations, a guinea pig model was developed in which transfer factor caused abrogation of tolerance to ABA-Tyrosine.

The study involves 10 children with primary immunologic deficiency of the humoral and cellular immunity diagnosed on the basis of the clinical symptoms of the disease and immunologic investigation. In 7 children, out of whome three were infants, suffering of recurrent respiratory tract infections, examinations revealed either absence or deficiency of the IgA in the serum and saliva. 2 children presented a classical picture of the Wiskott-Aldrich's syndrome followed by eczema, recurrent infections and trombocytopenia. Having studied the immunologic status in these two children in vitro and in vivo, the authors established deficiency in the humoral and cellular immunity. In an infant aged three months, with diagnosed histiocytosis X after histologic examination of the skin, the authors had examined the function of the T and B cells after which it was concluded that it was a case of rare form of the combined primary immunodeficiency.

We report a case of Wiskott-Aldrich syndrome in a 3 1/2-year-old boy. The patient developed reticulum cell sarcoma primarily in the brain; a biopsy specimen was obtained, and treatment with irradiation and chemotherapy was begun. Computerized tomography performed after three months of therapy showed remarkable regression of tumor. When the patient died five months postoperatively, no viable tumor was present; death was the result of pneumonia and sepsis. Only two previous cases of lymphoreticular neoplasm confined to the brain and associated with this syndrome have been described. We discuss the relationship between immunodeficiency and the occurrence of neoplasia in this syndrome.

Determinations of IgG subclasses were made by electroimmunoassay and crossed immunoelectrophoresis, and Gm markers were typed in sera from seventeen patients with well-defined immunodeficiency diseases. Certain IgG subclass and Gm patterns were recognized in various diseases: IgG2 deficiency and homozygosity of Gm (4,5) in the cartilage-hair-hypoplasia syndrome, in the ataxia telangiectasia syndrome and in selective IgG subclass deficiency; and IgG3 deficiency and homozygosity of Gm(1,-5) in the Wiskott-Aldrich syndrome. The findings suggest a common structural or regulator gene defect in some immunodeficiency diseases. In IgA deficiencies, the levels of IgG1 were raised. In patients with IgG subclass deficiencies there was sometimes a compensatory increase of the remaining IgG subclasses, with a preponderance of IgG1 and IgG3. The increased Ig1 showed restricted heterogeneity with only an increase of the electrophoretically cathodal part. This part contained both kappa and lambda chaings. IgG subclass deficiency indicates treatment with gammaglobulin even if the serum levels of IgG are normal or increased.

Within the group of diseases of immunodeficiency Wiscott-Aldrich syndrome can be excepted as one with well definical picture. Here presented are two patients with allness onset in the earliest childhood. Their chinical picture was a typical one showing often infections, thrombocytopenia and later appearance of eczema. Beside the dicreased number of the thrombocytes both patients had eosynophilia, changed immunoglobulines and lack of isohemogglutinin. One of them also showed low response to phytohemagglutinin and low values of the T and B rosettes. One of the patients lived until four years of age while the other one is aged five now and is in relatively good condition.

Concentrations of IgD and IgE were measured in sera from 165 patients with well-defined immunodeficiency in an effort to find information possibly relevant to the roles of antibodies of these classes in host defense. Values for both immunoglobulins were generally quite low in patients who had marked deficiencies of all three major immunoglobulins, although occasional normal or high normal values for IgD were seen in hypogammaglobulinemic patients. Group mean IgD concentrations were also depressed in patients with Wiskott-Aldrich syndrome and in those with selective IgA deficiency; IgE concentrations were depressed in patients with X-linked immunodeficiency with hyper-IgM and in those with ataxia telangiectasia. IgD and IgE were both significantly elevated in patients with extreme hyperimmunoglobulinemia E and undue susceptibility to infection and in a patient with the Nezelof syndrome; none of these patients had histories suggestive of atopy. In addition, the mean IgE concentration was significantly elevated in patients with selective IgA deficiency, many of whom were atopic, and in those with the Wiskott-Aldrich syndrome. The highest IgD concentration (163 mg/100 ml) was found in serum from a boy with variable immunodeficiency who had a lifelong history of severe recurrent pharyngeal infections, primarily streptococcal in etiology. Recurrent staphylococcal infection was a feature common to many but not all patients with elevated serum IgE concentration. These data may prove useful in the future delineation of biologic roles for antibodies in these two immunoglobulin classes.

Transfer factor was first discovered by Lawrence in 1955, but was not used therapeutically until 1969 when we reported its use in a Wiskott-Aldrich patient. Since that time, it has been used in a wide variety of disorders related to defects in cellular immunity, infectious diseases, and malignant diseases. This report describes our experience with transfer factor. Report number I discusses rationale for patient selection, procedures for transfer factor therapy, procedures for monitoring the efficacy of therapy, untoward effects of therapy, and experience with transfer factor therapy in severe combined dual system deficiency disorder. The results of our study on transfer factor therapy indicate that it is capable of inducing a clinically acceptable level of cell-mediated immunity in approximately 50% of patients with a variety of immunodeficiency disorders. It also appears to be a useful adjunct to chemotherapy, and may possibly act synergistically with transplanted fetal thymocytes to produce a constantly regenerating specifically competent source of T lymphocytes, thereby obviating the need for bone marrow transplant for severe combined dual system deficiency disorder.

The morphology of lymphatic tissues in 43 autopsy cases of children with inherited immunodeficiency states were analysed. Among the more common diseases, such as Di-George-syndrome, CID-patients, congenital agammaglobulinemia Bruton, CVID, selective IG-A deficiency, Wiskott-Aldrich-syndrome, tissue sections of very rare conditions associated with immunodeficiency, e.g. fetopathia diabetica and leprechaunismus, were investigated by routine and immunohistochemical stainings. Clinical history and laboratory data, augmented by the characteristic pathomorphology of lymphatic tissue sections, will establish or at least suggest a definite diagnosis. Since true thymic dysplasia is very rare (or even non-existent) in the human, this term should be abandoned. Severe thymic tissue alterations in SCID-patients, occur secondary to enzyme defects in lymphatic cells. If patients are successfully treated by bone marrow transplantation, the thymus will subsequently develop into a functionally normal organ.
