Twenty-nine adult patients with acute lymphocytic leukemia (ALL) were treated with combination chemotherapy consisting of behenoyl-ara-C, adriamycin, cyclophosphamide, vindesine and prednisolone (BHAC-ACVP regimen). Complete remission (CR) was obtained in 7 of 13 (54%) of the previously untreated, and 4 of 16 (25%) of the previously treated patients. Six of 10 (60%) L1 and 5 of 17 (29%) L2 patients achieved CR. Side effects such as nausea, GPT elevation and fever were observed, but these were not severe in most cases. The result indicates that BH-AC is useful for the treatment of adult patients with ALL.

Determining the current status of therapeutic results of acute lymphoblastic leukemia (ALL), and identifying the important clinical predictors of survival and relapse are essential for establishing therapeutic strategies. Sixty-two children with ALL who were admitted to Chonnam University Hospital from January 1983 to June 1991 were studied. With a mean follow-up period of 53.7 months, the overall 5-year survival rate (5YSR) was 46.1%. The overall rate of 5-year event-free survival (EFS) was 25.4% and significantly differed between risk groups: 48.7% for standard, 16.3% for high, and 12.5% for very high (p < .05). Overall 4-year survival after initial relapse was 34.2% and there was no significant difference in survival between those who relapsed during maintenance therapy and those who relapsed after completing maintenance. The Cox proportional hazards model identified central nervous system (CNS) irradiation (P < 0.001) as having the most important influence upon EFS, followed by serum alanine aminotransferase level, platelet level, and age. On the other hand, CNS leukemia at diagnosis, followed by mediastinal mass, and hemoglobin level were found to be the most important prognostic predictors for relapse. On the basis that present results differ from those of developed countries, we suggest the necessity of a nation-wide cohort study to delineate the characteristics of Korean ALL in children, to make our own protocols, and ultimately to improve the therapeutic outcome.

The effectiveness of sulbactam/cefoperazone (SBT/CPZ) on severe infections associated with hematological diseases was evaluated in a nation-wide multicenter clinical study. SBT/CPZ (4-6 g/day), a 1:1 combination of SBT and CPZ, was given intravenously to 437 patients with hematological disorders. The underlying diseases included acute nonlymphocytic leukemia, acute lymphocytic leukemia, malignant lymphoma, multiple myeloma, myelodysplastic syndrome and others. Thus, 94.3% of the patients had hematological malignancies. The complicating infections included sepsis in 41 cases; sepsis suspected in 205; pneumonia in 47; urinary tract infection in 15; fever of unknown origin in 59; and others in 70. Clinical efficacies of SBT/CPZ were as follows; markedly effective, 83 cases; effective, 170; fairly effective, 59; and ineffective, 110. The efficacy rate (markedly effective plus effective) was 60.0% as a whole. The efficacy rate of SBT/CPZ in sepsis and suspected cases, which accounted for 56.3% of the infections, was 59%. Mild side effects such as skin rash were observed in 15 patients (3.1%). As for abnormal laboratory test results, transient increases in GOT, GPT, A1-P, LDH, etc. were observed in 42 patients (8.6%). Therefore, SBT/CPZ is considered to be a useful drug in empiric therapy for severe infections associated with hematological diseases.

We studied 145 children with acute lymphocytic leukemia (ALL) in remission who had been off chemotherapy for at least 2 years, to assess the prevalence of hepatitis delta virus (HDV) infection, and to determine whether HDV infection was associated with more severe chronic liver disease. The prevalence of chronic HBV infection was 41.5% (60/145). The prevalence of HDV infection among these patients with chronic HBV infection was 50% (30/60). Eighty-five patients were HBsAg-negative. There was evidence that HDV-infected children had more severe chronic liver disease than did HBsAg-positive, anti-HDV-negative patients: (1) their serum ALT levels were significantly more likely to be elevated at long-term follow-up (27/30 vs. 10/26, p = 0.0001); (2) their mean ALT levels were significantly higher 3 years after the cessation of chemotherapy (128 vs. 84 IU/L, p = 0.001); and (3) they were more likely to have either chronic acute hepatitis or cirrhosis when liver biopsy was done (18/23 vs. 6/18, p = 0.0038). Children who were HBsAg-negative had the lowest alanine aminotransferase (ALT) levels and were least likely to have chronic active hepatitis or cirrhosis (3/31). We conclude that infection with HDV in children with ALL is associated with serious chronic liver disease. In long-term survivors, HDV infection is a major cause of morbidity and an adverse prognostic factor in terms of leukemia-free survival.

Forty-three patients with hematopoietic disease were treated with intensive chemotherapy and radiotherapy, followed by allogeneic bone marrow transplantation (BMT) from 28 HLA-identical and 10 one to two antigen haploidentical sibling donors and autologous BMT (5 cases). Of these cases, there were 21 with acute nonlymphocytic leukemia (ANLL), 5 with acute lymphocytic leukemia (ALL), 6 with chronic myelocytic leukemia (CML), 2 with Hodgkin's disease (HD), 8 with severe-form aplastic anemia (SAA) and 1 with thalassemia. Complications of BMT were evaluated including acute graft-versus-host disease (GVHD), interstitial pneumonia (IP), veno-occlusive liver disease (VOD), abnormalities of liver function (LF), and alteration of hepatitis B virus (HBV) markers. In thirty-three patients who were followed up for more than 3 months, we found that the incidence of moderate to severe acute GVHD (9.1%) and IP (two cases, 4.7%) were low. No VOD occurred in our series. During the follow-up period, 27 out of 35 patients (77%) had high alanine aminotransferase (ALT)/aspartate aminotransferase (AST) levels, even up to 1000 U/liter; however, only one patient succumbed to a hepatitis-related complication. Previous hepatic damage from HBV infection before BMT does not appear to increase the risk of posttransplant morbidity and mortality.

Fifty-nine children treated with acute lymphoblastic leukemia (ALL) were evaluated for abnormalities of liver function in order to monitor chemotherapy-induced hepatotoxicity. Twenty-one patients (36%) had elevations of alanine aminotransferase (ALT) in a pattern consistent with either drug-induced hepatocellular injury or non-A, non-B (NANB) hepatitis. These 21 patients (Group 1) were compared with the other 38 children (Group 2) with regard to a number of clinical and laboratory characteristics. Patients in Group 1 were older (P = 0.002) and had lower platelet counts (P less than 0.001) and hemoglobin values (P = 0.075) at diagnosis than Group 2 patients. The median number of units of blood products transfused was significantly greater in Group 1 patients (9.0 versus 1.0 units, P less than 0.001). The two groups were similar with regard to chemotherapy regimens. Children with ALL who present at an older age and who have more marked anemia and thrombocytopenia require more blood transfusions and are more likely to develop elevated ALT values in a pattern consistent with acute or chronic NANB hepatitis. These findings suggest a predominant role of NANB posttransfusion hepatitis--rather than or in addition to chemotherapy-induced hepatic injury--as a cause for elevated ALT values in children with ALL. In view of the potentially serious consequences of NANB hepatitis, a change in transfusion support practices may be warranted.

Five children, ages 2.5 to 12 years (mean 6.2 years), with acute lymphoblastic leukemia or non-Hodgkin's lymphoma were given 22 courses of high-dose methotrexate (HD-MTX) therapy (6-8 g/m2/24 h). No serious clinical complications were encountered, but stomatitis occurred after three (14%) of the courses. First-phase elimination half-lives (t1/2(alpha)) of MTX and 7-hydroxy-methotrexate (7-OH-MTX) after 21 infusions were 2.7 +/- 0.4 h and 6.5 +/- 1.8 h (mean +/- SD). In one course (4.5%) there was delayed systemic MTX elimination, with first-phase elimination half-lives (t1/2(alpha] for MTX and 7-OH-MTX of 4.2 and 9.9 h, respectively, and second-phase elimination half-lives (t1/2(beta)) of 43 and 58 h. Significant decreases in white blood cell count, increases in serum creatinine, and increases in alanine aminotransferase and/or aspartate aminotransferase during the first 2-6 days were present in five (23%), three (14%), and six (27%) of the courses, respectively. The regimen was tolerated well by the children.

Infected patients with hematological disorders were treated with the combination of cefmenoxime (CMX) and cefsulodin (CFS). This therapy was done on 74 patients, of whom 38 (51%) had acute myelocytic leukemia, 14 (19%) malignant lymphoma, 7 (9%) acute lymphocytic leukemia, 5 aplastic anemia, 4 adult T cell leukemia, 4 chronic myelocytic leukemia, 1 multiple myeloma and 1 histiocytic medullary reticulosis. Complicated infections included 5 cases of septicemia, 41 cases of suspected septicemia, 19 cases of respiratory tract infection, 2 with anal abscess, 1 with urinary tract infection and others. The obtained results were as follows: Clinical effectiveness of the combination therapy was excellent in 17 cases (23.0%), good in 24 (32.4%) and poor in 33 (44.6%). Total clinical efficacy rate was 55.4%. Clinical efficacy rate was 40% against septicemias, 51.2% against suspected septicemias and 57.9% against respiratory tract infections. Causative pathogens were isolated in only 21 cases (28.4%): Gram-positive bacteria in 9 cases, Gram-negative bacteria in 11 and fungus in 1. About half of the Gram-negative bacteria belonged to Pseudomonas sp. The efficacy rate of this combination therapy against Gram-negative bacterial infections was 72.7% but the rate against Gram-positive bacterial infections were only 33.3%. Only in 1 case, this combination therapy was discontinued because of drug eruption. Abnormal laboratory findings were observed in 5 cases: Elevation of BUN in 3, GOT and GPT in 1 and prolongation of activated partial thromboplastin time in 1. In conclusion, this combination therapy of CMX and CFS is useful and safe against infections complicated by hematological disorders.

A Phase II study of vindesine was carried out by the Vindesine Study Group in 130 patients with hematological malignancies: mainly 3 mg/body (about 2 mg/m2) of vindesine was administered once weekly by bolus injection. In 122 evaluable patients who had been heavily pretreated with vincristine and/or others, remissions were observed in patients with acute lymphocytic leukemia, blastic crisis of chronic myeloid leukemia, malignant lymphoma and other leukemias. The overall response rate was 39.3% including 20 complete and 28 partial remissions. No remissions were obtained in acute nonlymphocytic leukemia and multiple myeloma. All patients were evaluable for toxicity: Leukopenia occurred in 64.9%; peripheral neuropathy in 24.6%; GPT and GOT elevation in 20.7% and in 10.8%; alopecia in 11.5%; gastrointestinal disturbance in 10.8%; and fever in 5.4%. The treatment with vindesine was generally well tolerated, although in five out of 130 patients (3.8%) the treatment was discontinued due to convulsion, feeling of abdominal distention plus constipation, paralytic ileus, dysuria plus constipation, or interstitial pneumonia. Leukopenia and peripheral neuropathy appeared to be dose-limiting factors.

Cefoxitin (CFX) at a daily dose of 3 to 12 grams was administered to patients who had hematopoietic disorders as underlying diseases and having severe infections. Efficacy and safety of the drug were evaluated. The underlying diseases in the 64 patients included in the evaluation of efficacy were acute myelocytic leukemia (30 cases), acute lymphocytic leukemia (9), acute promyelocytic leukemia (3), acute monocytic leukemia (2), chronic myelocytic leukemia-blastic crisis (10), erythroleukemia (2), malignant lymphoma (2), aplastic anemia (2), and others (4). The infections were septicemia in 3 patients, suspected septicemia in 47, respiratory tract infections in 7, oral infections in 3, urinary tract infections in 2, and others in 2. The clinical efficacy of CFX was 'excellent' in 13 patients, 'good' in 26, 'fair' in 6, 'poor' in 19 for an efficacy rate of 60.9%. The efficacy rate classified according to infections was 66.7% in septicemia, 66.0% in suspected septicemia, 42.9% in respiratory tract infections and 66.7% in oral infection. The organisms isolated from the patients with septicemia were E. coli in 2 patients and B. cereus in 1. B. cereus was not susceptible to CFX. The efficacy rate was 60.0% in the 10 patients whose causative organisms were identified and 61.1% in the 54 patients whose causative organisms were not identified. There was no significant difference in the efficacy rate between the patients who had failed to respond to prior antibiotic therapy and those treated with CFX from the beginning. The efficacy rates for the former group (23 patients) and for the latter group (41 patients) were 56.5% and 63.4%, respectively. The efficacy rate in patients with an initial neutrophil count less than 500/mm3 (35 cases) and from 501 to 1,000/mm3 (13 cases) were 57.1% and 76.9%, respectively. Side effects which might have been caused by CFX were skin eruptions in 2 patients (2.6%) and transient elevation of GOT and GPT in 1 patient (1.3%) among 76 patients who were evaluated for safety. CFX was considered to be a markedly useful and safe drug in the treatment of patients with hematopoietic disorders who developed severe infections.
