Twenty-four perinatally HIV infected children received early treatment as soon as the diagnosis of viral contamination was established. In 13 cases (group 1), this diagnosis was based on a viremia and/or antigenemia during the first 6 months of life. In 11 cases (group 2), children were more than 15 months-old and had a positive HIV antibody test. Therapy included azidothymidine (AZT, 400 mg/m2/d) and the prevention of secondary infectious complications with intravenous immunoglobulin and cotrimoxazole. With a median follow-up of 26 months, we reported no case of severe secondary infection and no case of encephalopathy. Hematological side effects of AZT were rarely observed. Only one patient developed anemia. In all other cases, the only hematological abnormality was macrocytosis of red blood cells. Before treatment, the mean value of T4 cells age-adjusted count was 96, 86 and 91%, respectively, for groups 1, 2 and the entire study group. At the time of analysis, these values were 64, 62 and 63% respectively. This decrease was statistically significant for group 1 and for the entire study group, but did not reach statistical significance for group 2. These data show that AZT is probably insufficient as a long-term therapy for HIV infected children. Other therapeutic approaches need to be developed in the future, notably the combination of anti-retroviral drugs.

We report a case of a 61-year-old woman with large granular lymphocytosis associated with pulmonary tuberculosis. She was admitted to our hospital because of high fever, anemia and splenomegaly. On admission, the leukocyte count was 6,890/microliters with 52% of large granular lymphocytes. Immunophenotypical analysis of the increased cells showed following results; CD2+, CD3-, CD16+, CD57+. These cells had natural killer (NK) activity. Molecular genetical analysis showed these cells had germline configuration of the T cell receptor beta chain genes. About four months after admission, chest X-P revealed multiple mass shadow and the diagnosis of pulmonary tuberculosis was made by the examination of gastric juice. Anti-tuberculosis therapy was started, and soon after clinical symptom and pancytopenia were improved. For about one year, anti-tuberculosis therapy was continued, and now hematological abnormality is not found. We considered that this case was reactive large granular lymphocytosis of NK cells to lung tuberculosis.

The patient is a 39 year-old Japanese male who had traveled to Southeast Asia from March 14, 1987 and returned on April 2. On April 3 and 5, he had a high fever with chills and he was admitted to our hospital. Despite initial treatment with antibiotics, a high fever over 39 degrees C appeared with a 48 hour periodicity. On the 8th day after admission, malarial parasites were identified on the peripheral blood smear after repeated trials. Combined with a raised serum antibody titer, Plasmodium vivax malaria was diagnosed. He was successfully treated with the sulfadoxine 500 mg and pyrimethamine 25 mg (Fansidar) and body temperature was normalized after the 12th day. More interestingly, the patient showed pancytopenia without splenomegaly. The bone marrow aspiration revealed hypoplasia of erythroblasts, granulocytes and megakaryocytes. Because of this pancytopenia in the peripheral blood and hypoplasia of the bone marrow which improved after recovery from malarial infection, it was indicated that they were caused by the malarial infection. Generally, it is considered that anemia in malarial patients is caused by destruction of the blood cells by parasites and/or hypersplenism and compensatory hyperplasia of the bone marrow is seen. On the contrary, this case showed pancytopenia accompanied with hypoplasia of the bone marrow probably due to the malarial infection suggesting a new aspect of pathogenesis in the hematological abnormality of the malarial infection.

A series of 322 patients presenting with non-ulcerative conditions of the oral mucosa was examined for haematological abnormalities. The series was divided into 5 major groups--lichen planus (103 patients), candidiasis (50), leukoplakia (30), stomatitis or glossitis (66), and a miscellaneous group (73). The prevalence of anaemia, and deficiences in iron, folate and vitamin B12 in each group were compared with that found in 100 controls. The prevalence of anaemia in the series as a whole was not significantly increased, but the prevalences of sideropenia (14.0%), folate deficiency (4.7%) and vitamin B12 deficiency (3.1%) were increased as compared with controls. The prevalence of a haematological abnormality was increased in patients with lichen planus (18/103 p less than 0.05), stomatitis (15/66 p less than 0.01) and particularly in patients with Candidiasis (18/50 p less than 0.001). In the stomatitis group, approximately 45% of the male patients were found to have some haematological deficiency compared with less than 20% of the female patients. The increased prevalence of haematological deficiences suggests that patients presenting with non-ulcerative conditions of the oral mucosa (particularly candidiasis and non-specific stomatitis) should be screened haematologically and that, in some patients with candidiasis, haematological deficiencies may predispose towards candidal infection.

A study of 510 patients in Scotland and northeastern England with histological evidence of alcohol-induced liver disease showed no difference in the age of presentation between males and females. Single men and widowed females were particularly susceptible to alcoholic liver disease. The social class distribution was similar to the population in general. Women were more reluctant to volunteer a history of alcoholism than men, they had a higher incidence of previous psychiatric illness (usually due to alcohol abuse) and they developed liver disease at lower consumption thresholds of alcohol than men. Patients under 40 years of age were more likely to have alcoholic fatty liver and less likely to have active cirrhosis than those over 40. Most often, the presenting symptoms were non-specific and tended to be related to the gastrointestinal system, particularly in women. Five per cent of patients were asymptomatic and 14% came to hospital for conditions other than alcoholic liver disease. Important clues to asymptomatic alcoholic liver disease included hepatomegaly, clubbing of the fingers and abnormal liver function tests. Gastro-oesophageal varices accounted for 40% of instances of haemorrhage and the mortality from upper gastrointestinal bleeding was 17%. Anaemia was the most common haematological abnormality. Alcoholic hepatitis was observed more frequently in the Glasgow area then elsewhere.

The case histories of 4 patients who developed bone marrow damage after therapy with melphalan are described. In 3 patients bone marrow damage manifested initially as a sideroblastic anaemia which was later followed by acute myeloid leukaemia. The last patient developed a dyserythropoietic anaemia with leucopenia, but thus far there has been no further progression. None of the 4 patients had any haematological abnormality prior to the melphalan therapy. Two were suffering from carcinoma of the breast and 2 had ovarian neoplasms. The fact that melphalan was given as adjuvant therapy in all 4 patients prior to the development of the haematological abnormalities supports the concept that it was of aetiological importance. These findings are in line with a number of reports in the literature in which acute leukaemia has developed in subjects treated for malignant tumours (especially multiple myeloma and ovarian cancer) with melphalan.

The authors summarize their experience with 174 patients with aplastic anaemia (AA) with particular reference to course, prognostic factors, conversion to other blood disorders, treatment and outcome. Aplastic anaemia was defined as pancytopenia and a hypocellular marrow at some time during the illness. Seven patients terminated with acute leukaemia, 8 developed haematological features of sideroblastic anaemia and 5 showed a red cell membrane defect commonly found in paroxysmal noctural haemoglobinuria. Complete recovery occurred in only 4 patients; 70 others showed a partial remission with some residual haematological abnormality in peripheral blood. Eighteen of these had spontaneous remission. Remission was brief in 27 patients who died; only 32 patients remained in partial remission. Twenty-five per cent. of the patients with AA run an acute course and die within 6 months of the time of diagnosis. The remainder run a subacute or chronic course, punctuated in some cases by a transient remission, but in others by a conversion to other related haematological disorders. An acute course is suggested by a rapid onset of symptoms, a falling neutrophil count, a haemoglobin level less than 5 g/dl and a very low platelet count. A chronic course is likely in those patients who have a slow onset of symptoms, a stable neutrophil count and a Hb level in excess of 5 g/dl. The authors' experience shows that the disease runs either of the 2 courses irrespective of the supportive therapy.

The most common hematological abnormality associated with HIV infection is anaemia. The aetiology is multifactorial and may include the HIV virus itself; the anaemia of chronic diseases (ACD); infection with other viruses, mycobacteria and fungi; medications, especially zidovudine; and even B12 deficiency. Erythropoietin insufficiency is present in all anaemic AIDS patients, probably as a result of the mechanism of ACD. The studies, performed in patients with PGL, ARC and AIDS stages of disease demonstrate that rHuEPO is safe, and in dose of 100-200 U/kg b.w. three times a week can alleviate the anemia in AIDS patients taking AZT whose baseline EPO levels are less than 500 mU/ml.

Systemic lupus erythematosus (SLE) remains a disease of unknown origin, characterized by major alterations of both the cellular and the humoral arms of immunity. Hematological changes, including anaemia, leucopenia and thrombocytopenia, occur in more than one half of patients with this disease. Anaemia is the most common hematological abnormality seen in SLE. Its possible causes are anaemia of chronic disease (ACD), auto-immune haemolytic anaemia and hypoplastic anaemia. Leucopenia affects both granulocytic and lymphocytic lines and may be caused by autoantibodies. The influence of drugs, hypersplenism and marrow suppression are also possible. Thrombocytopenia occurs frequently and is almost invariably autoimmune. Patients with SLE are at increased risk of thrombosis. Haematological abnormalities in patients with this disease require careful long-term monitoring and prompt therapeutic intervention.

A 33 year-old man with undiagnosed neuropathy showing mental retardation and involuntary movements has been nourished for a long period by total parenteral nutrition (TPN) because of frequent vomiting and repeated aspiration pneumonitis. After ten months' TPN, macrocytic anemia and neutropenia developed and iron preparation was administered without hematological improvement. Bone marrow examination revealed normocellular marrow without features of megaloblastosis and dysplasia. In some erythroblasts and immature myeloid cells, vacuoles were observed and mature granulocytes were reduced in the bone marrow. Both serum copper and ceruloplasmin were very low (12 micrograms/dl and 7mg/dl, respectively). Thus, oral administration of copper sulfate resulted in marked increase of reticulocytes and subsequent improvement of anemia and neutropenia within two months. Copper deficiency is a rare condition, but during an unusual nutrition such as TNP, hematological abnormality due to copper deficiency must be noticed to occur.
