Management of variceal bleeding secondary to portal hypertension constitutes a challenging issue, particularly in child's C cirrhotic patients. Recently, transjugular placement of self-expanding metallic stents in the liver (TIPS), creating a shunt between the portal and hepatic branches has provided a safe and promising therapeutic approach in this clinical situation. We report here the case of a 66-year-old male cirrhotic patient who developed a moderately severe clinical picture of Coombsnegative hemolytic anemia (serum hemoglobin, 93 g/l, serum bilirubin 160.74 umol/L (9.4 mg/dl), indirect 6.3 mg/dl (107.73 umol/L); serum LDH 1220 mu/l, reticulocytes, 5.1%, serum ferritin 1221 micrograms/l, schistocytes in peripheral blood smear) the week after undergoing a TIPS, suggesting the development of microangiopathic hemolytic anaemia secondary to red blood cell disruption by passing through the metallic network of the stent.

An 84-year-old female was admitted to our hospital because of fever. Physical examination and computed tomography revealed hepatosplenomegaly without lymphadenopathy. Anemia and thrombocytopenia were noted and the serum levels of LDH, IL-6 and sIL-2R were elevated. Bone marrow aspiration showed infiltration of lymphoma cells and proliferation of histiocytes with hemophagocytosis. Southern blot analyses revealed rearrangements of both IgJH and IgJK genes. She received corticosteroids with improvement of her general state but she died on the 110th hospital day. Necropsy of the spleen showed diffusely proliferating large lymphoma cells, immunoreactive for B cell marker L-26, and scattered histiocytes with hemophagocytosis.

In order to reduce anaemia in patients with myelodysplastic syndromes (MDS) a stepwise treatment protocol including erythropoietin (EP) and granulocyte-macrophage colony-stimulating factor (GM-CSF) was designed. Thirty-seven MDS patients (stages I-III) with symptomatic anaemia were first given EPO 10,000 U s.c. 3 times weekly for 6 weeks. Those not responding, i.e. increased their haemoglobin levels > 15 g/l, proceeded into the second phase of the study where GM-CSF (200 micrograms/d. s.c. on weeks 1-6) was combined with EPO (10,000 U s.c. 3 times weekly on weeks 5-14). Following the initial EPO treatment phase, 14 of the 37 patients (38%) responded with increased haemoglobin levels. Responders were significantly different from non-responders in that their pre-treatment values of s-EPO, s-LDH and bone marrow blast cell counts were lower, their baseline haemoglobin levels higher and their transfusion dependency less pronounced. Eighteen of the 23 non-responders proceeded into the second phase, 13 of those were evaluable having completed the entire schedule. Three of the 13 initially EPO resistant patients (23%) responded to the GM-CSF/EPO combination with increased haemoglobin levels, suggesting a positive synergy between the two cytokines. Thus, the overall response rate to the present protocol was 46% (17 of 37 cases), but only a limited subset of the patients did clearly benefit from the combined GM-CSF/EPO administration. Therefore, we believe this step-wise approach to multiple growth factor treatment in MDS, starting with EPO alone and reserving the combination for refractory cases, has considerable advantages, taking into account both medical and socio-economical aspects.

A 70-year-old woman was admitted to our hospital in November 1992 for evaluation of anemia. Physical examination revealed anemia, jaundice, swelling of axial and inguinal lymph nodes, and splenomegaly. Abnormal hematological findings were as follows: Hb of 3.9 g/dl, reticulocyte count of 58.2% (61.7 x 10(4)/microliters), hyperplasia of normal erythroblasts in bone marrow, and eosinophilia (21.0%, 2352/microliters) in peripheral blood. Routine laboratory examinations revealed polycolonal hypergammaglobulinemia 3.0 g/dl, a high level of serum LDH (797 IU/I) and a total bilirubin of 2.4 mg/dl (indirect, 1.6 mg/dl). The serum haptoglobin level was very low (< 5 mg/dl). Results of serological examinations were as follows: IgG of 3366 mg/dl, CH50 of 16.0 U/ml, positive Coombs test 2+, and positive tests for antinuclear antibody, rheumatoid factor, and cold agglutinin. CRP was negative. PHA-stimulated lymphocyte blast formation, NK activity, and ADCC activity were found to be suppressed, and the percentage of CD4-positive lymphocytes in peripheral blood was also low. An axillary lymph node biopsy revealed reactive lymphadenitis. No signs or history suggested allergy, collagen disease, or parasitic infection. Autoimmune hemolytic anemia (AIHA) complicated by immunologic abnormalities and eosinophilia was diagnosed. Oral prednisolone markedly reduced the hemolytic anemia, eosinophilia, lymph node swelling, and splenomegaly, but NK activity remained low.

To study the role of erythropoietin (Epo) in the pathogenesis of anemia in acute renal failure (ARF), organ Epo mRNA was measured by RNase protection assay in rats with ARF induced by a one hour-occlusion of the left renal artery. Hematocrit was significantly decreased two hours, 24 hours and one week after renal artery occlusion. A significant reduction in serum haptoglobin at two hours and an increase in serum LDH at 24 hours indicated that hemolysis was the likely cause of the initial fall in hematocrit. However, despite the reduced hematocrit, serum Epo concentrations were not significantly different from controls, suggesting that the anemia is maintained because of lack of an appropriate Epo response. Right renal Epo mRNA levels were not significantly different in all groups, but Epo mRNA levels in post-ischemic kidneys were 50 to 67% lower than in contralateral kidneys. However, Epo mRNA in the post-ischemic kidney was increased sixfold by acute hemorrhage, a rise comparable to the ninefold increase observed in contralateral kidneys. In ARF rats exposed to 7.5% O2 for four hours, right kidney Epo mRNA increased 200-fold over normoxic levels, to a value similar to sham-operated hypoxic controls. Epo mRNA in the post-ischemic kidney also increased 200-fold, to 50% of the level in the contralateral kidney. Hepatic Epo mRNA levels were elevated to comparable levels in both groups. In this ARF model, mild anemia is associated with relative Epo deficiency. In the post-ischemic kidney, a substantial capacity for Epo production is retained but the sensitivity of the Epo response to blood oxygen availability is significantly reduced.

A 65-year-old woman was admitted to our hospital because of severe anemia. A skin biopsy was done in January 1994 and sarcoidosis was diagnosed. Diffuse reticular shadows were seen in both lung fields on a chest X-ray film and mediastinal lymph node swelling was seen on a chest CT scan. She was followed as an outpatient and was not treated. She suddenly experienced vertigo and general fatigue in March 1995. Laboratory findings on admission were as follows: Hb 6.2 g/dl, MCV 115.9 fl, Ret 198%, LDH 732 IU/L, I-Bil 1.9 mg/dl, and Coombs' test was positive. Autoimmune hemolytic anemia was diagnosed, and she was treated with prednisolone (1 mg/kg). As of the time of this writing, she has no relapse of hemolytic anemia though prednisolone was discontinued 6 months ago.

A 69-year-old woman was admitted with apoplexy after operation of mitral valve stenosis and gastrectomy due to a gastric ulcer. In June 1994, her condition gradually worsened after acute pneumoniae in her right lung. Intravenous hyperalimentation with cimetidine administration was started to improve her undernourishment, because she had a history of gastric ulcer. However, after 10 days from the start of cimetidine therapy, anemia progressed rapidly. Biochemical examinations revealed that the serum indirect bilirubin and LDH levels were elevated and no serum haptoglobin was detected. These results indicated the development of hemolytic anemia, but at that time we could not clarify the reason. In October 1994, thrombocytopenia gradually progressed, and we halted the administration of cimetidine to ranitidine. Both hemolytic anemia and thrombocytopenia was dramatically improved after cessation of cimetidine administration. We then changed the drug from cimetidine, however the same phenomena have appeared again. The patient was in stable condition, after cessation of H2-blockers administration. The complication of hemolytic anemia and thrombocytopenia associated with H2-blocker administration in Japan.

We have tried to elucidate the significance of so called non-infiltrative changes in order to find their place in the staging procedure particularly in countries where facilities for elaborate clinical staging are not available. Seventy nine out of 88 patients were classified into 3 groups depending upon the histological findings in their bone marrow trephine biopsies. Bone marrow in Group-I (n = 20) patients was essentially normal. The established criteria of bone marrow involvement were fulfilled in Group III patients (n = 25); while bone marrow in Group-II patients (n = 34) showed non-infiltrative changes. The clinical presentation, peripheral blood parameters and LDH levels of the 3 groups of patients were compared. There was progressive anaemia, neutrophilic leucocytosis and increase in ESR from Group I to III. The change was statistically significant when Group I was compared with Group II or Group III but non-significant when Group II was compared with Group III. It is, therefore, postulated that both Groups II and III reflect the bone marrow involvement although the changes observed in Group II do not satisfy the previously established criteria for this purpose.

Microcytic hypochromic red blood cells (RBC) were discovered in a 31 year-old Bangladeshi man. Additional laboratory data revealed only slight elevations of LDH and transaminase activities. The patient was clinically asymptomatic and showed no signs of anemia. On this basis, along with biochemical genetic analysis of hemoglobin, a diagnosis of hemoglobinopathy (HbE) was made. HbE is common in southeast Asia with over 30% of the population affected. Most people are asymptomatic. In northern Asia, including Japan, HbE is found in only 0.001% of the population. With ther recent influx of southeast Asians to Japan, care must be taken not to overlook the diagnosis of hemoglobinopathies.

The toxicity of Rhazya stricta leaves for Najdi sheep is described in 9 sheep assigned as untreated controls, Rhazya-treated at 0.25 g/kg/d and Rhazya-treated at 1 g/kg/d. The oral use of 1 g/kg/d caused body weight depression, ruminal bloat, diarrhea, dyspnea and weakness of the hind limbs. Enterohepatonephropathy, pulmonary congestion, hemorrhage and emphysema, lymphocytes in vital organs, and congestion of the blood vessels of the heart were associated with increases in serum AST and LDH, in elevated bilirubin and urea concentrations, and decreased total protein, albumin and calcium concentrations, and leucopenia and anemia.
