Nine cases affected with disseminated mucormycosis (1.3% of all autopsy cases and 20.0% of systemic mycosis) were found among bovine systemic mycosis examined from 1975 to 1985. The disseminated lesions were found in the lungs (3 cattle), heart (2 cattle), liver (2 cattle), spleen (1 beef cattle), kidneys (1 cattle), central nervous system (1 cattle) and lymph node (1 cattle). Histological examination revealed granulomatous lesions, necrotic foci including infarcts, and thromboangiitis with the hyphae of a member of the Zygomycetes and neutrophil reaction. Granulomatous lesions with asteroid bodies were found in the liver. Metastatic foci were established from the primary lesions found in the alimentary organ (4 from the forestomach or abomasum and 1 from the tongue). One case resulted from uterine mucormycosis, and no primary lesion was found in the other 3 cattle. Complicated infection with respiratory aspergillosis occurred in 4 cases with alimentary mucormycosis. All of the 9 cattle had predisposing disorders. Six cattle had been manifested with prolonged debilitating conditions. Anemia was present in 4, leukopenia in 2 and lymphopenia in 1 cattle.

Hematologic alterations are frequent in SLE. The hematologic changes of 111 patients diagnosed as suffering from SLE are described, associating them to 89 clinical, biological and hystological variables. The most frequent alteration was normocytic and normochromic anemia. Coombs positive hemolytic anemia appeared in 10% of the cases. Approximately 20% of patients had leukopenia. Lymphopenia was observed during the active period of the disease. Mild thrombocytopenia is common, as well as quality changes of the platelets. The sedimentation rate is high in nearly all patients with SLE and this is a non-specific index of the disease activity. These changes have seldom been described in our area.

In 65 natural cases of feline infectious peritonitis (FIP) the common clinicopathological changes included lymphopenia (77 per cent), neutrophilia (45 per cent), anaemia (37 per cent), hyperproteinaemia (39 per cent) and hyperglobulinaemia (39 per cent). There was no difference in the frequency of these abnormalities between the 38 cases of effusive disease and the 27 cases of non-effusive disease. The most consistent changes shown by serum protein electrophoresis were increases in alpha 2- and gamma-globulins. The protein content of the effusions ranged from 39 to 98 g/litre with the globulins comprising 50 to 82 per cent. Coronavirus serology showed a wide variation in antibody titres (0 to 2560) with 320 the modal titre. The diagnostic value of this information was evaluated by comparing it with data from 65 cats in which FIP was considered as a differential diagnosis, but another disease was diagnosed. None of the laboratory tests, including coronavirus serology, had good sensitivity and specificity for the diagnosis of the disease. The presence of multiple abnormalities compatible with the disease increased the specificity but decreased the sensitivity of the diagnosis.

The acquired immunodeficiency syndrome (AIDS) was first diagnosed in burundi in 1983 when a large number of patients were registered with Kaposi's sarcoma, cryptococcal meningitis, and disseminated candidiasis. In the 1st phase of the disease the vi rus is dormant. In the 2nd phase seroconversion appears; and in the 3rd phase generalized adenopathy emerges. In the 4th phase the full-blown disease appears as a result of cellular immunity deficit with emaciation, fever, sweating, chronic diarrhea, asthenia, blood parameter changes (lymphopenia, thrombocytopenia, leukopenia, anemia, and specific immune disorders). The early phases can be diagnosed by serological tests. During 1989 a group of 155 patients with 1st signs of seropositivity were studied in the central hospital of Bugumbura. The available clinical diagnostic markers were: 56 cases of herpes, 26 cases of generalized adenopathy, 25 cases of inflammatory infiltration of paraganglionic zones, 13 abscesses and phlegmons, 8 cases of chronic proctitis, 8 prurigo cases, 7 cases of chronic pneumonia and bronchitis, 4 cases of paresis of the facial nerve, 4 cases of Kaposi's sarcoma, 2 cases of fresh syphilis, 2 cases of anemia, asthenia, dizziness, and weight loss. Tomo- and zonographical X-ray study of the thorax of 80 patients aged 20-65 (51 men and 29 women) was performed. In 62 patients changes in the lungs were evident. In 2 patients tuberculosis of the lungs was diagnosed: miliary TB in a 26-year woman and disseminated TB in a 31-year man. 2 chronic and 3 bronchial, and 10 interstitial pneumonia cases were diagnosed in 15 patients with average age of 30 years. 4 patients had peribronchial and pneumonic infiltrations. In a group of 45 patients magnified picture showed no deformation in the lungs; and only 5 had respiratory organ pathology. Interstitial pneumonia was the most often diagnosed ailment by X-ray inpatients infected with HIV.

Study of 220 haematological profiles in women, men and children was realized in National Laboratory of Public Health and in Central Army Hospital in Brazzaville. The red cells count the haemoglobin level, the leucocytes and eosinophilia leukocyte counts in each sub-group of HIV+ and HIV- patients were compared. The anemia is important in HIV+ patients (Center for Diseases Control IV). The hyperleukocytosis and lymphocytosis of child and lymphopenia of adult are confirmed. The interest of surveillance of haematological parameters is as important for HIV+ asymptomatic individuals (Center for Diseases Control II) as for those of Center for Diseases Control IV group. The study of haematological profile is the interesting factor of diagnostic and prognosis.

In 4 years (1984-1987), 183 bone marrow examinations were performed on 155 human immunodeficiency virus (HIV) antibody positive patients. One hundred and fifty three had category IV AIDS. One-third of the marrows yielded specific information. This included opportunistic infection, in particular Mycobacterium Avium Intracellulare Complex (MAI) (24%), malignancy (4%), consistent with ITP (9%) and iron deficiency (1%). In the remaining two thirds of the bone marrows the most frequent non-specific abnormalities were dyserythropoiesis, erythroid hypoplasia, reticuloendothelial iron block, granulomas, lymphoid aggregates, plasmacytosis and histiocytosis. Common peripheral blood findings were anemia, lymphopenia, anisocytosis, rouleaux and atypical lymphocytes. Peripheral blood and bone marrow examinations on 16 patients on AZT are included. These patients have more pronounced blood and bone marrow abnormalities. The causes of these abnormalities are multifactorial and include low T4 levels, severe viral and other infections and therapy with marrow toxic drugs.

Angioimmunoblastic lymphadenopathy (AILD), first discovered in the 70's, is an infrequent disease which generally proves fatal within a short time. It is characterized by lymphadenopathies, hepatosplenomegaly, fever and rash. The most frequent laboratory findings are: anemia, leukocytosis with lymphopenia and non specific hypergammaglobulinemia. In spite of being considered a non malignant disease, it produces important immunity disorders which predispose the patient to serious infections, frequently fatal. In the course of time patients are likely to develop malignant lymphomas or other types of tumors. We describe a ganglionar proliferation and general symptoms in a patient who had been diagnosed as AILD by ganglionar biopsy. She was treated with corticosteroids during 8 months after which she had a complete recovery. Three months later the patient was readmitted with enterrorhagias and clear deterioration of her general condition. Tests showed the existence of a colon tumor and absence of adenomegaly in the areas previously affected by AILD. A colon surgery was carried out and a specimen examined. The anatomopathologic examination confirmed the existence of an immunoblastic lymphoma infiltrating the regional ganglionar area. Colon lymphomas constitute only 4% of all colon tumors; they are related to chronic gastrointestinal disease such as Crohn disease, ulcerative colitis, malabsorption syndromes, tumors and others. We conclude that in this patient AILD and prednisone administration constituted favoring factors for the development of an extranodal lymphoma.

Toxicity of environmental pollutants may be expressed as combined effects of a chemicals. Benzene, a proven hematotoxic agent, frequently occurs with toluene in cocontaminated groundwater. Groups of CD-1 male mice were exposed continuously for 4 weeks to benzene (166 mg/l), toluene (80 and 325 mg/l), and combinations of benzene (166 mg/l) + toluene (80 mg/l or 325 mg/l) in drinking water. Benzene-induced anemia was alleviated by simultaneous toluene treatment. Leukopenia and lymphopenia were observed in the case of benzene only and benzene + toluene (80 mg/l)-treated mice. The cytopenia, however, was less severe in the benzene + toluene (325 mg/l)-treated group. Immunotoxicity induced by benzene treatment alone was characterized by involution of thymic mass and suppressions of both B- and T-cell mitogeneses, mixed lymphocyte culture response to alloantigens, the tumor lytic ability of cytotoxic T-lymphocytes as determined by 51Cr-release assay, and antibody production response to T-dependent antigen (sheep red blood cells). IL-2 secretion by Con A-stimulated mouse T-cells was decreased in the benzene-treated group. Toluene (325 mg/l) completely inhibited these adverse effects when it was coadministered with benzene, while the low dose of toluene (80 mg/l) did not protect against benzene-induced depressions of immune functions. Toluene administered alone at levels up to 325 mg/l showed no obvious immunotoxic effects. Results of this study demonstrated that toluene, in sufficient amounts, has an antagonistic effect on benzene immunotoxicity.

Levels of mature lymphocytes, granulocytes, macrophages, platelets, their progenitor cells, and cytokines were monitored in the blood, marrow, and spleen during fatal or nonfatal murine malarial infections. In all four malaria models, before anemia developed, there was a lymphopenia, a rapid lymphocyte depletion in the marrow with a compensating rise in spleen lymphocytes, thrombocytopenia with increased megakaryocytic progenitor cell numbers, and monocyte increases in the bone marrow and later the spleen. The development of anemia was associated with a monocytosis and neutropenia, an increase in granulomonocytic progenitor cells in the spleen, and a reduction of spleen lymphocytes. Spleen granulocytes, monocytes, and their progenitor cells increased two- to threefold more in nonfatal than in fatal malaria and the spleen lymphocyte pool became severely depleted in fatal malaria. The data suggest that a defective effector cell response was of importance for the fatal outcome of the disease. Other than an early rise in serum macrophage colony stimulating factor levels in fatal infections, changes in levels of the regulators of these effector cells did not correlate well with the outcome of the infection.

A spontaneous large granular lymphocyte leukemia from a F344 rat was transplanted to 36 syngeneic recipients to study the interactions among leukemia, T lymphocytes, and the development of immunemediated hemolytic anemia. Six rats were euthanatized at biweekly intervals, and spleen weight, total spleen cellularity, and differential spleen cell counts were correlated with hemograms and osmotic fragility. Sequential changes in splenic architecture were correlated with hematologic parameters. Monoclonal antibodies defining all T lymphocytes (W3/13), T helper-inducer cells (W3/25), and T suppressor cells (OX-8) were used to identify T cells in immunocytochemical techniques on spleen sections, as well as in fluorescence activated cell sorter analysis of spleen cell suspensions. The onset of hemolytic anemic at 7 weeks after transplantation coincided with the first detection of tumor cells in the spleen and peripheral blood. Tumor cells first accumulated in the marginal zones, and then they infiltrated the red pulp sinusoids. Although the leukemia caused dispersion of the splenic lymphoid tissue, there was no significant lymphopenia, and the relative number of helper (W3/25+) and suppressor (OX-8+) lymphocytes did not change. Because the induction of anemia was a relatively early event in splenic involvement, we concluded that anemia was unrelated to disruption of lymphoid architecture; furthermore, it does not appear to be caused by changes in the numbers of regulatory T lymphocytes.
