Two cases of T-cell chronic lymphoid leukaemia in adults were classified by recently developed immunological methods. Clinically there was splenomegaly, hepatomegaly, marked anaemia, para-aortic lymph nodes, cutaneous infiltration, little peripheral lymph-node enlargement and significant marrow infiltration. Immunological tests of membrane antigens revealed T-cell determinants. T-CLL may differ in its course and prognosis from B-CLL and may require different treatment.

We describe retrospectively the experience with 44 cases of AIDS from January 1987 to October 1991 at the Instituto Nacional de Pediatria, a tertiary care children hospital in Mexico City. All patients with 2 ELISA and a positive Western Blot test were included. Thirty three patients were infected perinatally (75%) and 11 through blood transfusion (25%). Fourty one patients belonged to the P2 classification of the Centers for Disease Control. Chronic diarrhea (77%), lymphadenopathy (75%), hepatomegaly/splenomegaly (70%) and oral candidiasis (61%) were the most common clinical findings. Twenty patients died (45.4%). No statistical relation were found between survival rate and the way of transmission and age at onset. Autopsy was performed in 14 patients and revealed a sharp decrease of lymphoid tissue at all levels with severe thymic atrophy.

This report deals with an unusual case of primary macroglobulinemia with hypercalcemia, chronic renal failure and systemic amyloidosis. In May 1990, a 63-year-old male was transferred to our hospital because of hypercalcemia (13.5 mg/dl) and renal failure. Clinical examinations showed anemia, macroglossia, lymph node swellings and hepatomegaly. Laboratory findings included Bence-Jones (kappa type) proteinuria (0.8 g/day), a monoclonal gammopathy of the IgM-kappa type (2.8 g/dl), a proliferation of lymphoid cells in the peripheral blood (5%) and the bone marrow (59.6%), and lymphomatous involvement of an inguinal lymph node. Serum creatinine concentration was 8.5 mg/dl. The serum levels of parathormone and vitamin D3 metabolites were normal. The roentgenogram of bones showed a compression fracture of the lumbar spine and systemic osteoporosis. The treatment included eel calcitonin, prednisolone and the CHOP regimen, followed by hemodialysis and plasmapheresis. The serum level of IgM increased to 4.6 g/dl. The patient died three months later and postmortem examination demonstrated marked systemic amyloidosis.

Scurfy (sf), is an X-linked recessive lethal mutation that occurs spontaneously in the C3H mouse. The disease is characterized by lymphoid and hematopoietic dysfunction. Affected males are of small stature and exhibit scaliness and crusting of the eyelids, ears, tail, and feet, marked splenomegaly, moderate hepatomegaly, enlarged lymph nodes, and atrophy of the thymus. The average lifespan of the affected hemizygous males (sf/y) is 24 +/- 0.7 days. Total cellular proteins were extracted from pooled samples of thymus and spleen obtained from combined litters of mice. Tissue-specific protein profiles characteristic of either sf mutant or normal mice were analyzed by two dimensional polyacrylamide gel electrophoresis (2DPAGE) at different stages of the phenotypic expression of the sf mutation, to identify changes in protein patterns that might be associated with the progression of the disease. The resultant gels were silver stained, digitized, and analyzed, by image analysis utilizing a pipelined image processor connected to a host computer. At 14 +/- 1 days of age, protein patterns from sf mutant and normal mice control organs showed considerable homogeneity, although there were proteins identified unique to the sf mutant and to the normal controls. At 20 +/- 1 days of age, the pattern differences between the sf mutant and normal control increased markedly. Differences were expressed as the percent of proteins that were unique to either the sf mutant or the normal control from the total number of each type. The percent of proteins that increased or decreased in the three organs utilized in this study ranged between 21%-39% at 14 days and were between 25%-54% at 20 days. Differences in protein expression between the normal and sf mutant as the disorder progressed for each of the three tissues examined. In addition, thymus protein profiles from 9 day old littermates that were phenotypically normal but genotypically unknown were evaluated to determine if marker proteins could be identified for the sf mutation. Limited protein changes were noted at relative molecular weights of 66, 60, 54, 39, 37, 33, 25, 23, 27, and 11 kDa. These data suggest that the sf mutation follows a trackable pattern of protein expression and repression different than the normal control C3H mouse. Several potential marker proteins associated with the sf mutation were identified in 9 day thymus prior to the phenotypic expression of the disease. These putative biomarkers may be useful for characterizing the sf mutation and the mutant may act a possible model the Wiskott-Aldrich syndrome (WAS).

Spontaneous lymphomas from a strain of hereditary cataract (CAC-nct/+) mice were examined by light and electron microscopy and by immunohistochemical reaction for the mouse heavy and light immunoglobulin chains. Lymphomas occurred in 28 out of 45 male cataract mice and in 34 out of 52 females at 25 to 65 weeks of age. All of the lymphoma-bearing mice showed an enlargement of the spleen and mesenteric lymph nodes, and some mice also had hepatomegaly. Morphologically, all tumors were composed of a mixed population of small and large cells. Neoplastic cells had features of follicular center cell lymphomas, such as scant to moderate amounts of cytoplasm and cleaved and/or round nuclei with a large nuclear-to-cytoplasmic ratio. Large cells were often admixed with small cells, and had vesicular nuclei with prominent nucleoli juxtaposed to the nuclear membrane. Intracytoplasmic eosinophilic inclusions were observed in occasional cells, but Golgi apparatus was poorly developed and rough-surfaced endoplasmic reticulum was scant, unlike those in plasma cells. C-particles were seen in all lymphoma-bearing mice by electron microscopy. Intracisternal A-particles were detected in some mice. Immunohistochemically, neoplastic lymphoid cells were positive for the kappa light chain and the surface/cytoplasmic immunoglobulin M. These results indicate that lymphoid cell neoplasms found in hereditary cataract mice originate from follicular center B cells.

A 63 year-old woman was referred to our hospital because of fever and increased number of blasts in the bone marrow. On physical examination she had slight hepatomegaly but no splenomegaly. Laboratory tests disclosed a hemoglobin level of 8.5 g/dl; a WBC count of 13,200/microliter with 26% blasts; a platelet count of 51,000/microliter. A bone marrow aspirate was normocellular with 74% blasts and 37% blasts were stained positive for myeloperoxidase. Cell surface markers for HLA-DR, CD10, CD19, CD13, CD33 were positive. Karyotype analysis revealed 46, XX, t (9q+; 22q-) and 45XX, -7, t (9q+; 22q-). Southern analysis showed rearrangement of immunoglobulin heavy chain but not T cell receptor beta gene. Rearrangements in M-BCR were not detected with 5' or 3' bcr probes. After 2 courses of chemotherapy, blasts decreased to 7% with recovery of normal elements and 11 out of 20 metaphases of the bone marrow cells were normal karyotype. These findings suggest that this case was de novo Ph1 positive acute leukemia which demonstrated both lymphoid and myeloid features.

Adult T-cell leukemia/lymphoma (ATLL) is an HTLV-I associated lymphoid malignancy frequently seen in Japan. Abdominal involvement in 40 patients with ATLL were assessed by ultrasonography and the findings seen in four clinical types, acute, chronic, lymphoma and smoldering, were compared. Splenomegaly was frequently found in the cases of acute and lymphoma types, and the sizes of the spleens measured by ultrasonography correlated well with the disease activity. Hepatomegaly was also found more frequently in acute and lymphoma types, and hepatosplenomegaly was proved to be due to the infiltration by ATL cells. Nodular lesions in spleen and liver and abdominal lymph node swelling were also found frequently in the lymphoma type but rarely in the other types. Ascites, pleural effusion, and pericardial effusion were found in the active stage of acute and lymphoma types. Ultransonography also could detect findings associated with therapies. Thus, ultrasonography studies were found to be very useful for assessing the clinical classification, examining various pathological conditions associated with ATLL, and monitoring the disease activity.

CD-1 mice were given oral doses of 0-16 ml/kg/day for five days of Prudhoe Bay (PBCO), South Louisiana and Arabian Light crude oils, Bunker C oil (BCO), mineral oil (MO) and corn oil. Minor decreases in packed cell volume and increases in mean corpuscular hemoglobin concentration occurred after ingestion of crude oils and BCO. Dietary depletion of vitamin E and selenium failed to enhance hematological changes. Pronounced liver enlargement and atrophy of thymus and spleen accompanied ingestion of all petroleum oils except MO and were shown to be dependent on dose of PBCO. Concentration of RNA and total RNA were increased while total DNA, but not concentration of DNA, was increased in enlarged livers. Liver enlargement was attributed primarily to hyperplasia with an additional contribution due to hypertrophy. The severe hemolytic anemia reported in marine birds that ingested PBCO was not reproduced in mice. Liver enlargement and lymphoid tissue atrophy were similar to those reported in other species exposed to petroleum oils.

A 33-year-old man was hospitalized because of thrombocytopenia and severe splenomegaly. On admission 78% of peripheral lymphoid cells were abnormally large, with pale cytoplasm. Flow cytometry of the abnormal lymphocytes showed that they expressed CD 2, CD 3, CD 11, CD 16, and CD 56, but not CD 4 nor CD 8, so they were T-cell large granular lymphocytes (T-LGL). Abnormal lymphocytes obtained from a lymph node expressed CD 2, CD 16, CD 38, and CD 56, but not CD 3, CD 4, and CD 8, so they were natural killer(NK) cells. Splenectomy was performed and the operative specimen showed diffuse infiltration of pleomorphic lymphocytes, probably chronic lymphocytic leukemia cells. After splenectomy, the platelet count returned to normal but the lymphocytosis continued. Two years after discharge, chemotherapy was done because of thrombocytopenia and hepatomegaly. The patient died of disseminated intravascular coagulation arising from sepsis. The differences and similarities between peripheral and lymph-node lymphocytes suggest that LGL and NK cells may be differentiated from the same kind of cell, somewhat differentiated from stem cells.

After the intraperitoneal injection of corpuscles of C. burnetii antigen (Ag), phospholipid (PL), and sediment obtained after the extraction of PL from Ag with chloroform-methanol (CM) slight leukocytic reaction developed in the peritoneum on day 1, and on day 2 it could be observed in the liver and in the spleen. Ag induced the most pronounced morphological changes. In the spleen they were manifested by the activation of T- and B-dependent zones of white pulp from day 2 and by the pronounced hyperplasia of reticular cells and macrophages, leading to splenomegaly, by days 7-14. Simultaneously lymphoid-macrophagal granulomas and hepatomegaly developed in the liver. By days 7-14 the foci of necrosis in the liver were caused by the thrombosis of portal veins and were not registered after the injection of PL and CM (and earlier also in experiments with Ag in doses of 0.1-0.3 mg).
