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.

Circulating antibodies against certain nuclear acidic protein antigens have been shown to have diagnostic and prognostic importance in connective tissue disease. We describe a new precipitin system found in the sera of patients with systemic lupus erythematosus. The antigen, called MA, was prepared from calf thymus nuclei, and was shown to be distinct from other nuclear acidic protein antigens by physicochemical and immunologic techniques. MA antibodies were detected in the serum of 12 of 66 lupus patients and in none of 554 sera from normal controls or patients with other rheumatic diseases. Lupus patients having MA antibodies had more severe disease than did lupus patients with Sm or native DNA antibodies, manifested by recalcitrant skin rashes and a significantly greater incidence of hypocomplementemia, serious renal disease, hypertension, hepatosplenomegaly, lymphadenopathy, and neurological disease (P values range from 0.025 to 0.005). The presence of circulating MA antigen was demonstrated in three lupus patients immediately before a flare of nephritis. These data suggest that MA is a nuclear acidic protein antigen that may identify a subset of lupus patients with very severe disease. The presence of the antigen in the circulation before clinical flares suggests a possible biologic role for the MA system in an immune complex nephritis.

The case is reported of a 4-year-old girl affected with recurrent infections; anaemia, thrombocytopenia, haemorrhages and hepatosplenomegaly. Immunological investigations revealed a defect in cellular immunity related to the thymus-dependent system, hypergammaglobulinaemia (especially of class IgE), and very high titres of antibodies against Epstein-Barr virus (EBV). After foetal thymus transplantation, correction of the immunological defect and significant clinical improvement were noted, as well as a decrease of IgE and EBV antibody titres.

The occurrence of T system immunodeficiency in an infant together with excessive production of IgM and, to a lesser degree, of IgG and IgA, is an unusual combination. A case is reported in which an unremitting lung infection with lymphadenopathy and hepatosplenomegaly developed in a previously healthy two-month-old infant. Leukocytosis with lymphocytosis, monocytosis and eosinophilia was rapidly followed by leukopenia and lymphocytepenia after a blood transfusion for anemia. There was a transient clinical remission, but on relapse 10 days later, quantitative and functional T cell deficiency was found together with increased IgG and IgA and with IgM values reaching 50 times greater than normal. Thymic humoral factor was successful in vitro in increasing the number of identifiable T cells (E rosetts) as well as T cell function (leukocyte migration inhibition factor production). However, the infant died suddenly, and at autopsy evidence of a generalized inflammatory reaction compatible with a viral infection was found. The thymus was small, hypoplastic and hypocellular. It is speculated that the T system deficiency may have been acquired following Epstein-Barr virus infection, and that T cell regulatory activity of immunoglobulin production was defective.

A case of histiocytic medullary reticulosis in which nasal involvement was predominant is reported. The patient was a 33-year-old woman with a 14-month history of unilateral nasal stuffiness. The diagnosis was established by antemortem examination of films of bone marrow aspirates and by clinical features including fever, wasting, hepatosplenomegaly, anemia, and leukopenia. The histologic examination of autopsy specimens disclosed proliferation of histiocytes, which ingested nuclear debris and closed proliferation of histiocytes, which ingested nuclear debris and erythrocytes, in the necrotic lesion of the nose, sternal bone marrow, liver, spleen, thymus, uterus, ovali, and ileum. On reviewing literature on this subject, such a case of histiocytic medullary reticulosis which predominantly involves the nose is very rare.

Monozygotic twin boys presented at 1 year of age with seborrheic skin rash, otorrhea, and hepatosplenomegaly. Skin biopsy confirmed Langerhans cell histiocytosis. Treatment with conventional antineoplastic drugs and with calf thymus extract was ineffective. The disease remained refractory to recombinant human alpha-interferon and to low-dose total body irradiation, and the children died between 3 and 3 1/2 years of age.

During an epidemic of visceral leishmaniasis in the Sudan, two cases of congenital kala-azar were seen. The first child, whose mother had contracted kala-azar in southern Sudan, was born in Khartoum, where no transmission of leishmaniasis is currently occurring. At seven months, the child had fever, lymphadenopathy, and hepatosplenomegaly; leishmania parasites were detected in the bone marrow. The child died and an autopsy showed leishmania parasites in all tissues including the lungs, kidneys, and thymus. In the second case, parasites were found in the placenta of a five-month-old fetus. These two cases demonstrate the importance of follow-up of infants born to mothers with leishmaniasis.

Two male siblings, one aged five and a half months (SB), and the other aged six months (VB), with fatal infectious mononucleosis phenotype of the X-linked lymphoproliferative syndrome, which resulted in the death of both infants, are presented. Both patients had been healthy, one until the age of five and a half months, and the other until the age of six months. Then, they developed a maculopapular rash, hepatosplenomegaly and lymphadenopathy. In one sibling, the serum IgG level was low, the IgM and IgA levels were high, and the proportion of E-rosette forming cells (E-RFC) and in vitro proliferative response to PHA were normal. In the other sibling, however, the serum IgG level was normal, the IgM and IgA levels were high and the stimulation index for proliferative response to PHA was reduced due to increased spontaneous blastogenesis. Anti-EBV antibodies were negative in both siblings, except for the IgM anti-VCA in V.B. A lymph node specimen could be studied in one infant and was found to be positive for the EBV genome. Postmortem histopathological findings included the absence of cortico-medullary differentiation and identifiable Hassal's corpuscles in the thymus and depletion of T-dependent regions of lymph nodes and spleen in V.B. Atypical mononuclear cell infiltration was detected in the portal areas of the postmortem liver biopsy in S.B.

The C57BL/KsJ spm/spm mouse, an animal model of Niemann-Pick disease, shows defective sphingomyelinase activity resulting in accumulation of sphingomyelin in various organs. To replace the defective enzyme, allogeneic bone marrow-plus-liver transplantation was performed. Bone marrow transplantation with or without concomitant liver grafting in C57BL/KsJ spm/spm mice at the age of 2-9 weeks led to an amelioration of the hepatosplenomegaly. The treatment, however, neither prevented the development of neurological signs nor increased the life-span. The sphingomyelin and cholesterol contents of the liver decreased, while sphingomyelinase activity in the liver increased after bone marrow transplantation. Foam cells disappeared from the bone marrow, liver, spleen, thymus, and lymph nodes, but depletion of Purkinje cells was not prevented. These results suggest that bone marrow transplantation either alone or with liver transplantation may become a useful strategy for the treatment of Niemann-Pick disease provided the central nervous system is not involved.

We experienced a surgical case of large Hodgkin's lymphoma of the thymus. An 18 year-old male who had been complaining of a persistent cough was admitted to our hospital. Chest X-ray film showed an anterosuperior mediastinal tumor. But there was no superficial lymphadenopathy and hepatosplenomegaly. He received a surgical extirpation of the tumor approached by median sternotomy. The tumor expanded to the whole antero superior mediastinal region, which was 18.5 X 15 X 5.5 cm in size, surrounding the trachea and main branch of aortic arch and veins. The tumor directly invaded the bilateral pleura and left innominate vein, so these regions were resected with the tumor. The left innominate vein was reconstructed with a PTFE graft. The pathological diagnosis was Hodgkin's lymphoma nodular sclerosis type by LSG classification. A post operative course was uneventful.
