In the treatment of acute leukoses, from the first onset of the disease till the occurrence of the first remission, as well as in the course of intesive hemiotherapy, the substitution therapy by blood derivatives has the great importance. Anaemia, granulocytopenia, hypoproteinaemia and hemorrhagic syndroms, caused by thrombocytopenia, liver diseases and disseminated intravascular coagulation, are the most frequent disorders requiring the substitution therapy. Authors presented the advantages of the substitution therapy by blood derivatives upon the whole blood.

1. The calcium channel blocker, nicardipine, produced a dose-dependent reduction in the mortality caused by endotoxin in rats. 2. The drug also reduced most of the hematological and gross pathological manifestations of disseminated intravascular coagulation (DIC) caused by endotoxin. 3. The endotoxin-induced monocytopenia but not the granulocytopenia, lymphocytopenia or thrombocytopenia was inhibited by the drug. 4. The results suggest that the protective action of nicardipine is causally related to prevention of the endotoxin-induced DIC and that an effect of the drug on monocytes may be of importance.

A 51-year-old male, who had a history of excessive drinking and chronic hepatitis, was admitted to our hospital because of high fever and shock. Physical examinations, chest X-ray films and hemodynamic data revealed that he had progressed to septic shock due to pneumonia. Combination chemotherapy of latamoxef plus piperacillin was immediately started. After Klebsiella pneumoniae was isolated from bronchoalveolar lavage fluid, the antibiotics were changed to ceftizoxime plus amikacin. Furthermore human gamma globulin preparations and frozen fractional plasma were administered because of granulocytopenia and a decrease in complement. Gabexate mesylate, methylprednisolone (MP) and branched chain amino acids were given to prevent disseminated intravascular coagulation and/or multiple organ failure. With this intensive care, he recovered from shock and pneumonia. The effects of MP on the whole blood chemiluminescence (CL) were examined. Incubation of whole blood with 25, 50 or 100 micrograms/ml of MP for 10 to 60 minutes had no effects on the CL response. This indicates that MP does not affect the production of reactive oxygen species from phagocytic cells at concentrations comparable to those used in drug therapy.

We experienced 57 episodes of Pseudomonas aeruginosa bacteremia in 55 patients with hematologic disorders in a 16-year period. Ninety-five percent of the patients had hematologic malignancies such as acute leukemia. All but one patient received cytotoxic or immunosuppressive therapy at or prior to the onset of bacteremia. Seventy-seven percent of the episodes occurred during profound granulocytopenia of below 100/mm3. All the patients acquired their infection in the hospital, and 96% had received antibiotic therapy during the preceding two weeks. Periodontal, anorectal, lower respiratory tract, and urogenital infections were the sources of bacteremia in about three-quarters of the episodes. Periodontal infection tended to progress to cellulitis of the face or the floor of the mouth, often resulting in bacteremia of the unimicrobial type, while anorectal infection predisposed to abscess formation, frequently leading to bacteremia of the polymicrobial type. Cellulitis at onset was seen in 35% of the episodes. Most sites of infection did not become apparent until one to three days after the onset of fever, probably because of depressed inflammatory response associated with severe granulocytopenia. The majority of patients complained of gastrointestinal symptoms such as nausea and vomiting, abdominal pain, diarrhea, and abdominal fullness at the onset of bacteremia. Major complications included bacteremic shock (63%), impaired consciousness (25%), ecthyma gangrenosum or hemorrhagic gangrenous cellulitis (18%), and jaundice (12%). Furthermore, there were one case each of endocarditis and disseminated intravascular coagulation. It was thus suggested that the clinical picture of P. aeruginosa bacteremia complicating hematologic disorders is influenced by the predisposing conditions associated with the underlying diseases and their treatment.

Although a 39-year-old male received the curative operation of total gastrectomy for advanced scirrhous carcinoma of the stomach, recurrence of cancer was occurred soon after the surgery, accompanied by hemorrhagic diathesis from DIC. The abdominal CT scan examination revealed the rapid enlargement in the size of the several lymphnodes around the abdominal aorta, and the blood chemistry tests showed marked increase of the serum CEA value. The sequential chemotherapy with intermediate dose of MTX and 5-FU in conjunction with OK-432 was started to treat the case. This chemotherapy was carried out once a week for 5 times and consequently DIC was led to the perfect remission. Furthermore, CEA level decreased within normal range, and the size of the enlarged lymphnodes at paraaortic area diminished remarkably. Although he complained of nausea and loss of appetite during the treatment, no severe adverse effects such as granulocytopenia, diarrhea, or loss of hair were observed. The successful result in this patient suggests that sequential therapy of intermediate dose of MTX and 5-FU with administration of OK-432 may be effective in the treatment of advanced scirrhous carcinoma of the stomach.

Clinical features and specific aspects of treatment were evaluated in 612 patients with gram-negative bacteremia observed over a 10 year period. Coagulation abnormalities or thrombocytopenia were observed in 64 per cent of the patients. Evidence of disseminated intravascular coagulation (DIC) was found in approximately 10 per cent of them but was of sufficient severity to be associated with subcutaneous or visceral bleeding in 3 per cent of them. The frequency of coagulation abnormalities, other than DIC, was greater in patients with more severe underlying disease but DIC occurred with similar frequency irrespective of the severity of underyling host disease. Coagulation abnormalities of all types were associated with increased fatality rates. Hypothermia was noted in 13 per cent of the patients at the onset of bacteremia but was transient and was not associated with increased fatality. Failure to mount a febrile response greater than 99.6 degrees F within the first 24 hours of bacteremia was associated with a significant increase in fatality rates. Prior corticosteroid therapy diminished the febrile response to bacteremia. Age, underlying host disease, granulocytopenia, congestive heart failure, diabetes mellitus, renal insufficiency, nosocomial infections, and antecedent treatment with antibiotics, corticosteroids, and antimetabolites significantly increased fatality rates. Appropriate antibiotic treatment reduced the fatality rate of those with bacteremia by approximately one-half among patients in each category of severity of underlying host disease. In addition, it was shown that early appropriate antibiotic therapy also reduced the frequency with which shock developed by one half. Even after development of shock, appropriate antibiotic therapy significantly reduced fatality rates. The use of combinations of antibiotics could not be demonstrated to significantly improve survival rates. Minimal differences in therapeutic efficacy could be demonstrated between individual antibiotics and various combinations of antimicrobials. Shock occurred in approximately 40 per cent of the patients and its frequency was not influenced by the species of etiologic agent. Contrary to previous reports, corticosteroid therapy in patients with shock did not enhance survival and treatment with an average of 4.0 g/day of hydrocortisone or its equivalents was associated with a significant increase in fatality rates.

Assessment of peripheral blood counts and blood film analysis are frequently performed as diagnostic procedures in emergency medicine. Far fewer situations exist, however, in which these analyses are the main clue in establishing an emergency diagnosis. Artifacts can lead to wrong diagnosis, e.g. pseudo-thrombocytopenia, which is defined as a low platelet count resulting from a laboratory artifact. Severe neutropenia (agranulocytosis) and extreme hyperleukocytosis, as well as suspicion of acute leukemia, require a rapid diagnostic work-up. A newly detected anemia should not necessarily be treated by packed red cell transfusions. The decision whether an anemic patient ought to receive transfusions should be based on the speed with which the anemia has developed, as well as on clinical judgement. As a rule a chronic anemia patient with hemoglobin above 70 g/l does not need transfusions. An uncritical transfusion policy can even cause emergencies, e.g. in patients with megaloblastic anemia or in anemic multiple myeloma patients with a hyperviscosity syndrome. An elevated hematocrit requires prompt further investigations. This is of utmost importance if one considers the diagnosis of polycythemia vera rubra, a disease in which patients are particularly prone to thrombotic complications. Fragmented red cells (schistocytes) on peripheral blood smears constitute a cardinal diagnostic clue for the detection of microangiopathic hemolytic anemias (MAHA), in particular for the diagnosis of the life-threatening thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). Malaria is another example for a chief role of blood smears examination in achieving a rapid diagnosis. If one encounters an unexpected severe thrombocytopenia, a marrow examination reveals whether it is due to rapid peripheral destruction, or due to a marrow failure. Furthermore, in any patients with an unanticipated thrombocytopenia, a disseminated intravascular coagulation and a MAHA should be ruled out. Heparin-induced thrombocytopenia is a rare, but possibly fatal complication of therapy with heparins.

We report 4 acute promyelocytic leukemia cases that demonstrated karyotypic abnormalities in addition to the classic t(15;17) translocation and did not contain any Auer rods in leukemic blasts and dysplastic promyelocytes, either in the peripheral blood or in the bone marrow. Morphologically, 2 cases were characterized as the common or hypergranular type, and 2 were otherwise typical of the microgranular variant. Three patients had typical clinical and laboratory signs of disseminated intravascular coagulation. Immunophenotypic analysis of the blasts and dysplastic promyelocytes by dual-color flow cytometry revealed an immunoprofile consistent with acute promyelocytic leukemia. Cytogenetic analysis of the bone marrow revealed the following karyotypes: case 1, [47,XY,t(15;17)(q22;q12),+21]; case 2, [47,XY,t(15;17)(q22;q12),-16,+2 mar]; case 3, [47,XX,t(15;17)(q22;q12)ider(17)(q10),+8]; and case 4, [47,XY,der(5)t(5;?9)(p15;q12).t(15;17)(q22;q12]. Review of an additional 7 cases with t(15;17) as the sole cytogenetic abnormality revealed Auer rods in all cases. Our findings emphasize the importance of cytogenetics in evaluating acute myeloid leukemias. Acute promyelocytic leukemia without Auer rods, which may be morphologically confused with other types of leukemia (in particular, acute myeloblastic leukemia, type M2 or M5) or agranulocytosis with maturation arrest, appears to be associated with additional chromosomal abnormalities and possibly a poorer prognosis.

Agranulocytosis caused by ethosuximide is extremely rare in children. Drug-induced agranulocytosis is an unexpected side effect of a drug, and delay in diagnosis of agranulocytosis can result in a fatal outcome. We experienced a case of a 16-month-old male infant with Down syndrome in whom fever appeared 16 days after the start of administration of ethosuximide and then severe pneumonia developed. Results of a blood test on admission showed a decreased leukocyte count of 1700/microl, and a hemogram showed that there were no granulocytes. The erythrocyte and thrombocyte counts were within normal ranges. The results of a bone marrow aspiration test showed that there was no production of any types of granulocytes. The patient required mechanical ventilation due to deterioration in his pneumonia and complication with disseminated intravascular coagulation, but the neutrophilic leukocytes began to increase from the 8th day after discontinuation of ethosuximide administration and start of treatment with granulocyte colony-stimulating factor, and the patient survived. The mechanism of onset in this case is thought to have been immunologic. Careful attention should be given to this type of agranulocytosis because of its sudden onset at 1-2 weeks after the start of administration of the causal drug. A drug-induced lymphocyte stimulation test was useful for diagnosis in this case, showing a positive reaction only for ethosuximide.

The side effects of high-dose anti-cancer drug chemotherapy with peripheral blood stem cell transplantation (PBCST) for the treatment of intractable testicular tumor are very serious. In particular, agranulocytosis in bone marrow suppression may be life threatening. In this study, we examined opportunistic infectious diseases and preventive counter measures in the compromised conditions of anti-cancer drug chemotherapy. The patients underwent anti-cancer drug chemotherapy with PBCST for the treatment of intractable testicular tumors at Kobe University Hospital from September 1996 to September 2002. The high-dose chemotherapy regimen consisted of total doses per course of 1,250 mg/m2 carboplatin, 1,500 mg/m2 etoposide, and 7,500 mg/m2 ifosfamide. Twenty-four men (median age, 30 years; range, 18-70 years) received 50 courses of chemotherapy in total. The nadir of peripheral leukocyte counts was less than 1,000/mm3 in all courses, and the mean period was for 7.1 days. None of these patients developed critical sepsis leading to disseminated intravascular coagulation or treatment-related death. Our detailed data show that we can perform high-dose anti-cancer drug chemotherapy with PBSCT for intractable testicular tumors without serious infectious complications if we take sufficient preventive countermeasures for infectious diseases.
