A 64-year-old slaughterhouse worker with advanced non-Hodgkin's lymphoma developed septicemia and pneumonia. Mycoplasma arginini, a wall-free prokaryote found in a variety of domestic animal hosts, was repeatedly isolated from blood and bronchial washings from the patient. Immunosuppression, in part caused by hypogammaglobulinemia, probably played a key role in predisposing the patient to a fatal infection. This case suggests that animal mycoplasmas should be considered in the list of infectious agents acquired by immunosuppressed hosts.

Patients with X-linked lymphoproliferative (XLP) disease are characterized by extreme vulnerability to Epstein-Barr virus (EBV). Following infection with EBV, affected males develop fatal infectious mononucleosis (IM), hypogammaglobulinemia (H), or non-Hodgkin's lymphoma (NHL). In addition, hyper IgM, red cell aplasia, necrotizing lymphoid vasculitis (NLV), and aplastic anemia occur rarely. The recent use of DNA restriction fragment length polymorphism (RFLP) probes in linkage with the XLP gene now permit detection of affected males prior to primary EBV infection. We have measured immunoglobulin class and subclass levels in sera from EBV-negative males who were either positive or negative for the XLP genotype by RFLP analysis. Elevated IgA or IgM and/or variable deficiency of IgG, IgG1, and IgG3 occurred in the sera of 13/13 RFLP-positive, EBV-negative males. No consistent abnormalities were noted in 14 RFLP-negative, EBV-negative males. We conclude that the immune defect in XLP is not solely EBV-specific, although EBV is responsible for most of the morbidity and all of the mortality. Further, serial measurement of Ig levels may provide information regarding status of EBV-negative males at risk where RFLP analysis is uninformative or in families where sporadic cases of fatal IM, acquired hypogammaglobulinemia or NHL have occurred, but wherein the genotype of XLP cannot be documented.

A randomized crossover study of prophylactic immunoglobulin (IgG) therapy was performed in patients with chronic lymphocytic leukaemia (CLL) or non-Hodgkin's lymphoma (NHL). Twelve patients with hypogammaglobulinemia or a history of recurrent infections received infusions of IgG or placebo intravenously (IV) every 3 weeks for 1 year. They were then switched to the alternative preparation for another year. The number of serious bacterial infections was significantly less (P = .001; Mainland's cross-over method) in the months in which patients received IgG. Serious bacterial infections showed a trend to be associated with an IgG level less than 6.4 g/L (P = .046; Fisher's exact test).

Seven patients with autoimmune hemolytic anemia (AIHA) associated with an underlying lymphoproliferative disorder were treated with intravenous immunoglobulin. Five patients with chronic lymphocytic leukemia, a patient with Hodgkin's lymphoma with severe AIHA associated with a "warm" IgG antibody, and a patient with non-Hodgkin's lymphoma with an IgM "cold" antibody were treated with intravenous immunoglobulin G (0.4 g/kg) daily for five doses followed by maintenance therapy every 21 to 28 days if evidence of recurrence was noted. Two additional patients with refractory chronic lymphocytic leukemia and hypogammaglobulinemia were given maintenance therapy with intravenous immunoglobulin G every 21 days for previously recurrent AIHA and infections. Hematocrit levels of patients with AIHA stabilized followed by a gradual improvement at 21 days after intravenous immunoglobulin G infusion without steroids. Treatment with steroids and intravenous immunoglobulin G resulted in faster and higher increments in hematocrit levels in these patients. Other patients who had partial responses to steroids showed further improvement in their hematocrit levels by the addition of intravenous immunoglobulin G. Another patient with a cold agglutinin disease was refractory to intravenous immunoglobulin G therapy. Five patients with chronic lymphocytic leukemia and acute AIHA and two patients with previous recurrences of AIHA required maintenance intravenous immunoglobulin G every 21 days. All seven patients except one did not have any episodes of AIHA from six months to as long as four years while receiving the three-week intravenous immunoglobulin G therapy. These observations indicate a role for intravenous immunoglobulin G in the management of IgG-mediated but not IgM-associated autoimmune hemolysis in immunocompromised patients with lymphoproliferative diseases.

The total lymphocyte, T, B, and null cell content of peripheral blood from 32 healthy individuals and 30 patients with non-Hodgkin's lymphoma was determined. The patients had a significant reduction of B cells (complement receptor and membrane immunoglobulin positive cells) and a significant reduction in T cells. Correlation of patients' characteristics with lymphocyte abnormalities demonstrated several findings. Patients with advanced disease (III and IV) had significantly lower total lymphocyte and T cells than patients with localized disease (I and II) or normal controls. Patients with hypogammaglobulinemia had lower total lymphocyte and T cells than patients with normal gamma globulin status or normal controls. Patients with diffuse histology and B symptoms had lower total lymphocyte and T cells than normal controls. Discriminant analysis of lymphocyte populations categorized patients by disease extent and gamma globulin status with 70 and 68% accuracy, respectively.

A case of a 7-year-old boy with common variable hypogammaglobulinemia who developed B-cell-type non-Hodgkin's lymphoma is reported. Immunologic studies of his peripheral blood before the development of lymphoma revealed: (1) although peripheral T-cell and B-cell counts were normal, serum IgG and IgA levels were remarkably reduced; (2) DNA synthesis in response to phytohemagglutinin-P (PHA), concanavalin A (Con A), and pokeweed mitogen (PWM) stimulation were decreased; (3) DNA synthesis in response to EBV was enhanced; (4) in vitro IgG production with the patient's peripheral blood lymphocytes was significantly depressed; and (5) helper and suppressor activities of the patient's T-cells did not differ from that of normal controls. Six months after the investigation systemic involvement of malignant lymphoma appeared. The lymphoma was diagnosed as a lymphoblastic diffuse one. Lymph node cell marker analysis revealed that the lymphoblasts had surface mu and kappa chain, cytoplasmic IgM, and HLA-DR antigen. Blastogenesis of B-cell series may be suppressed by a feedback mechanism with the B-cells and antibody. In the current case, impairment of such a mechanism with defect of immunoglobulin production might finally induce malignant B-lymphoid proliferation.

A patient with angioimmunoblastic lymphadenopathy was treated with chemotherapy to complete remission for 13 years. A single relapse, self-limited, occurred followed 2 years later by the appearance of a disseminated non-Hodgkin's lymphoma with prominent cutaneous lesions and hypogammaglobulinemia. Cells from the peripheral blood and an affected lymph node were characterized by immunologic studies as deriving from the T8 subset of lymphocytes, suggesting a functional relationship between these suppressor cells and the patient's clinical manifestations.

We describe a woman with lymphoid interstitial pneumonia diagnosed by open lung biopsy following a profile of unproductive cough, weakness and bilateral lung infiltrates. The patient was also diagnosed as having common variable immunodeficiency based on hypogammaglobulinemia, repeated sinusitis and persistent diarrhea. Exfoliative cytology of pleural effusion revealed the development of non-Hodgkin's lymphoma. We review the associations among these processes and consider the suggestion made by other authors that lymphoid interstitial pneumonia be considered a prelymphomatous process.

A 58-year-old man was admitted to our hospital because of recurrent pulmonary infections that began three years previously. Laboratory data showed hypogammaglobulinemia and a chest computed tomogram showed diffuse bilateral micronodular shadows and an anterior mediastinal tumor. Immunodeficiency with thymoma (Good's syndrome) was diagnosed. After undergoing a thymectomy, he received intravenous gamma-globulin injections once a month for prophylaxis. Good's syndrome occurs rarely in Japan. A solid tumor-like shadow is not necessarily observed in routine chest X-ray studies, and hypogammaglobulinemia is one sign of this syndrome. The hypogammaglobulinemia of Good's syndrome should be carefully differentiated from that of other immunodeficiency diseases such as common variable immunodeficiency, the acquired immunodeficiency syndrome, chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and multiple myeloma (non-secretory type).

We report the occurrence of X-linked lymphoproliferative disease (XLP) in two brothers in a Malaysian family. In this disorder, a primary Epstein-Barr virus (EBV) infection is followed by an abnormal proliferation of transformed B-cells that cannot be controlled by suppressor T-cells, leading to the development of deranged immune function. This results in fatal infectious mononucleosis, acquired hypogammaglobulinaemia, virus-infected haemophagocytic syndrome and non-Hodgkin's lymphoma. The diagnosis should be considered when there is a family history of any male having a fulminant course of infectious mononucleosis, an otherwise benign disease. Early diagnosis is important as bone marrow transplantation is the only curative option in this disorder.
