Bone marrow transplantation can be considered in any disease state resulting in the malfunction or absence of part or all bone marrow elements. Diseases such as aplastic anemia, leukemia, and immunodeficiency disease are being treated with bone marrow transplantation. As with any organ transplant, graft rejection is a possibility. In bone marrow transplantation, there is the additional, unique problem of graft versus host disease. In order to prevent or minimize graft rejection, the immunocompetence of the recipient and the degree of disparity between donor and recipient at the major histocompatibility complex (MHC) loci are considered. The results of bone marrow transplantation are variable, and the mortality rate is still relatively high. However, progress is being made, and in many instances, normal bone marrow function can be restored in patients with whom other treatment has failed.

A chronic, debilitating syndrome related to graft-versus-host disease (GVHD) has been recognized in long-term survivors following allogeneic bone marrow transplantation. In six of 20 marrow graft recipients who survived for more than one year after receiving a transplant, this complication developed; they were studied to better define the syndrome. There was no association between the sex of either donor or recipient, HLA type, blood group, conditioning regimen or marrow cell dose and subsequent development of chronic GVHD. All six patients had mild to moderate manifestations of acute GVHD following prompt engraftment. Chronic GVHD was characterized in each patient by progression to scleroderma-like skin involvement with hyperkeratosis, reticular hyperpigmentation, atrophy with ulceration and fibrosis with limitation of joint movement. A sicca syndrome was prominent in five patients. Four patients had idiopathic interstitial pneumonitis. Infectious complications were frequent, and DNA viral infections were prominent. Autoimmune hemolytic anemia was present in three patients, and one patient had antinuclear antibody (ANA). A spectrum of immune abnormalities was observed including hypergammaglobulinemia, immunoglobulin M (IgM) paraprotein, elevated circulating immune complexes, plasma cell hyperplasia, lymphocytotoxic antibodies and autoantibodies to autologous or donor lymphocytes. Despite clinical similarity to collagen vascular diseases, none of these patients had anti-DNA antibodies or antibodies to smooth muscle, thyroid or extractable nuclear antigens. In one patient, a skin graft from the marrow donor remained healthy despite progressive involvement in recipient skin, whereas unrelated skin grafts were rejected. Immunosuppressive therapy and plasmapheresis have not been effective. Four patients have died (median survival 458 days from transplantation). Chronic GVHD appears to be a syndrome of disordered immune regulation features of immunodeficiency and autoimmunity.

In a clinical study the tolerance and efficacy of a gamma-globulin, treated at pH 4, has been studied. This preparation manufactured by the "Zentrallaboratorium des Blutspendedienstes SRK" can be given intravenously without any risk of untoward reactions. It has been applied in high dosages up to 99 g per week. In 15 cases with primary humoral immunodeficiency, the frequency and the severity of acute bacterial infections were markedly reduced or completely absent. In 16 patients without antibody deficiency but suffering from severe septic-toxic infections, results with Immunglobulin SRK were encouraging and warrant further controlled studies.

A patient with an inborn cellular immunodeficiency syndrome developed a graft-versus-host reaction after a transfusion with packed red cells. This diagnosis was confirmed by skin biopsy and finally proved by tissue typing.

Bone marrow transplantation is an experimental approach to the treatment of patients with acute leukemia, aplastic anemia, and other neoplastic and genetic diseases. To date, long-term disease-free survival has been achieved in a small proportion of carefully selected patients with resistant acute leukemia. While results are not optimal, they are acceptable in late stage patients where there are no effective alterates. Major problems in marrow transplantation for leukemia include tumor resistance and a spectrum of immunologic complications including GVHD, immunodeficiency, and interstitial pneumonitis. Potential approaches to these problems have been suggested. Progress in any one area would have a substantial impact on improving survival and extending the applicability of marrow transplantation to patients at an earlier stage of their disease.

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.

A large inbred family is described in which there were seven cases of Hodgkin's disease, three of lymphosarcoma, two of thymoma, two of common variable immunodeficiency, and single cases of retinoblastoma, neuroblastoma, and rhabdomyosarcoma. There have been no other lymphoma cases in the community during the past decade. Further study of this family may help to define the genetic basis for development of Hodgkin's disease and other disorders.

Human polymyositis and aspects of myasthenia gravis may be consequences of subtle immunodeficiency states. Autoimmune processes leading to inflammatory muscle disease and the presence of associated tumours may reflect the partial loss of antibody-mediated homoeostatic mechanisms.

Of 18 boys in Duncan kindred, 6 died of a lymphoproliferative disease. They exhibited a subtle, progressive combined variable immunodeficiency disease characterised by benign or malignant proliferation of lymphocytes, histiocytosis, and alterations in concentrations of serum-immunoglobulins. Infectious mononucleosis occurred during or preceding terminal events in at least 3 of the cousins. Fever, pharyngitis, lymphadenomegaly, hepatosplenomegaly, atypical lymphocytosis, and a spectrum ranging from agammaglobulinaemia to polyclonal hyper-gammaglobulinaemia occurred. At necropsy, the thymus gland and thymic-dependent areas in the lymph-nodes and spleen were depleted of lymphocytes. Diffuse infiltrates composed of lymphocytes, plasma cells, and histiocytes, some containing erythrocytes, invaded the haematopoietic organs, viscera, and central nervous system. In addition, 2 half-brothers had lymphomas of the ileum and central nervous system. Approximately half the boys, including the half-brothers, were affected, and girls were spared, implying sex-linked recessive inheritance. Various lymphohistiocytoses resemble Duncan's disease, but it is distinctive from them in the mode of inheritance or by histiological characteristics. This study suggests that the Epstein-Barr virus or other viruses triggered the fatal proliferation of lymphocytes and that progressive attrition of T-cell functions allowed uncontrolled lymphoproliferation.

A 5-year-old girl with a history of recurrent infection and anaemia has no measurable purine nucleoside phosphorylase (N.P.) activity in her red blood-cells. Her serum-immunoglobulin levels are normal, as are her antibody responses to thymus dependent and independent antigens. However, she has severe lymphopenia, pronounced depression of lymphocyte response to mitogenic and allogeneic cell stimuli, and greatly decreased T-cell rosette formation. Her parents are second cousins; their red cells contain less than half the normal level of N.P. activity. They also share an unusual N.P. isozyme pattern indicative of molecular hybridisation between catalytically active and inactive subunits, which strongly supports the assumption that they are heterozygous and their daughter is homozygous for a "silent" allele at the N.P. gene locus. Inherited deficiency of adenosine deaminase, an enzyme catalysing a reaction only one metabolic step away from that of N.P., is known to cause immunodeficiency. It is therefore very likely that this patient's lack of demonstrable N.P. activity is responsible for her syndrome.
