Two hundred and sixty-two patients (actual number 162) of hematological malignancies were admitted to our department from November 1977 to December 1986. Fourty-three of them (16.4%) were demonstrated to be accompanied with sepsis by blood culture. In acute non-lymphocytic leukemias (AML, APL, AMoL) the rate of sepsis was 33.8% (27 patients), while in lymphocytic malignancies (ML, HD, ATL) it was 11.7% (16 patients), particularly being 3.0% in ATL. Among the detected pathogenic microorganisms, gram-negative bacilli were 86.2% in the former and 50.0% in the latter. Especially, Pseudomonas aeruginosa, Klebsiella pneumoniae and Escherichia coli occupied 58.6% of the total in the former. Laboratory examination, when sepsis occurred, revealed peripheral neutropenia in acute non-lymphocytic leukemias (mean 831/cmm) but not in lymphocytic malignancy (mean 4,420/cmm). And 20 of the 27 cases showed remarkable neutropenia of below 500/cmm in the former. On the other hand in the latter, out of 16 only one with ATL was the case. Hypogammaglobulinemia was one of the characteristic features in lymphocytic malignancies but not in acute non-lymphocytic leukemias. Hypogammaglobulinemia in lymphocytic malignancies might be affected by long-term immunodepressant therapy. Immunologic skin reaction was demonstrated to be decreased in lymphocytic malignancies on admission. From the findings mentioned above, affecting factors to infections may be mainly neutropenia in acute non-lymphocytic leukemias and immunodeficiency in lymphocytic malignancies. And sepsis can occur frequently under neutropenic condition. In ATL both of humoral- and cellular-immunologic disturbance were detected before therapy. But peripheral neutrophil count was maintained to be normal and this could be the reason for the low septic incidence in ATL despite of total immunodepression.

A 31-year-old Hispanic man presented in the pancytopenic phase of acute myelocytic leukemia and was treated with the chemotherapeutic agents mitoxantrone and cytarabine. After 5 days, an erythematous, blanching, papular, crusted eruption developed on his forehead, chest, and legs. Some lesions showed confluence and all were at the same developmental stage. Clinical diagnoses included necrotizing vasculitis and sepsis. A biopsy specimen revealed widespread noninflammatory syringometaplasia of eccrine ducts. Well-developed intercellular bridges and eosinophilic cytoplasm were seen within the metaplastic cells; apoptoses and occasional mitoses were present. This process is distinct and probably occurred secondary to direct toxic injury from the chemotherapeutic drugs. Because similar changes have occurred in patients with neutrophilic eccrine hidradenitis, we believe our patient represents an example of the noninflammatory end of the spectrum of chemotherapeutic eccrine gland reactions.

A phase I/II study of recombinant human granulocyte colony-stimulating factor (rhG-CSF) in 24 leukemia patients was conducted at our institute. Recombinant human G-CSF (50-200 micrograms/m2/day) was administered i.v. In seven allogeneic bone marrow transplantation (BMT) recipients, treatment with rhG-CSF was started 5 days after BMT. Neutrophils began to increase within 3 days after the start of rhG-CSF administration in five of seven patients. The mean duration necessary for recovery of neutrophils to greater than 500/microliters was 11.3 days after BMT with rhG-CSF; 26.8 days is the figure for recovery without rhG-CSF from Japanese historical data. In seven out of eight patients who received rhG-CSF administration after the first remission-induction chemotherapy, the neutrophil counts increased from less than 300/microliters to greater than 4000/microliters within 10 days. Blasts did not increase in all patients including four acute nonlymphocytic leukemia (ANLL) patients. Severe infections such as septicemia and pneumonia, which were unable to be controlled by antibiotics only, were successfully treated with rhG-CSF and antibiotics. rhG-CSF either stimulated or inhibited myeloid leukemic cells in some refractory cases. Mild bone pain occurred in one patient while receiving rhG-CSF i.v. rhG-CSF seems to have the ability to shorten the period of neutropenia, prevent infections after allogeneic BMT and remission-induction chemotherapy for acute leukemia, and support therapy for infections.

In the present study plasma fibronectin levels were determined in patients with hematopoietic malignancy, particularly leukemias, in an effort to clarify their clinical implications. Among leukemia patients, those with AML, ALL, ATL or CLL had various plasma fibronectin levels that were higher in some cases, while lower in others, as compared to normal control values. An elevation of the fibronectin level was noted often in APL, while lower fibronectin values were observed in many instances of CML. In these types of leukemia, acute exacerbation as well as supervention of infection tended to be associated with lower than normal levels of fibronectin. An especially marked depression of fibronectin occurred, when leukemia was complicated by sepsis or DIC, in which a good parallel was noted between the progress of disease and the fibronectin level. In lymphoproliferative diseases, the fibronectin value varied widely, but low fibronectin levels were frequently associated with intercurrent infection or an extreme deterioration of the general physical conditions.

A patient with acute myeloblastic leukemia (AML) developed septicemia due to Bacillus cereus with subsequent rhabdomyolysis and myoglobinuric renal failure. He died despite intensive care. Postmortem examination revealed diffuse muscle necrosis with infiltration of Gram-positive bacilli and widespread bacterial microthrombi in various organs. Septicemia associated with rhabdomyolysis has been described in 12 cases. This case represents the first reported case of B. cereus septicemia associated rhabdomyolysis. Renal failure and shock were considered to be the most important prognostic factors, and either direct infiltration or toxin of the bacteria was suggested to be the mechanism of rhabdomyolysis in sepsis. B. cereus can be one of the lethal organisms in immunocompromised patient such as the present case. Rhabdomyolysis should be considered when a patient with septicemia complains of muscle pain. Prompt hydration and correction of acidosis are important to prevent renal failure and shock.

A total of 23 patients with high-risk acute myelogenous leukemia (AML) at diagnosis (2 patients), relapsing AML (14) or resistant AML (6) were treated with 25 micrograms/kg i.v. plicamycin every other day for 3 weeks and 500-4,000 mg hydroxyurea per day p. o. according to the WBC count. Aplasia was observed in only two patients. Severe extrahematologic toxicity included sepsis (four cases), vomiting (four patients), toxic hepatitis (three cases), and fibrinopenia (one patient). No partial or complete responses were observed. The 95% confidence interval limit of the overall response rate (CR + PR) was 0-14%.

We optimized the modulation of drug resistance by the irreversible augmentation of cytotoxicity of coincubating vinblastine (VNB) with VP-16 and the reversible increase in cytotoxicity of coincubation of verapamil (VPL) with VNB and VP-16. VPL was administered as a loading dose (i.v.) (0.15 mg/kg) and then administered as a constant infusion (0.005 mg/kg) over 6 days. 24 h after verapamil, VNB 2 mg/m2 IVP was administered and followed 1 h later by a 5-day simultaneous continuous infusion of VP-16 (200 mg/m2/day) to seven pediatric patients (11 courses) with refractory malignancies. The mean age at treatment was 7.5 +/- 5.3 years, mean prior anthracycline dose (303 +/- 210 mg/m2) with a range of 0-606 mg/m2. Toxicity was limited to cardiac and hematological. The median nadir of the WBC was 900 at 14.5 +/- 0.5 days and platelet count 32,000 at 15.5 +/- 0.8 days. There were two episodes of bacterial sepsis both of which responded to i.v. antibiotics. Five of 11 courses resulted in first-degree block and one course in second-degree block. At Hour 120 of the VPL infusion the PR interval was 0.18 +/- 0.01 versus 0.13 +/- 0.01 at Hour 0 (P less than 0.0004). The ejection fraction by two-dimensional echocardiogram was not significantly different at Hour 0, 24, or 120 of the infusion (60.6 +/- 2.7 versus 52.7 +/- 5.1 versus 51.8 +/- 5.0%). The cardiac index was also not significantly different at Hour 0, 24, or 120 (4.39 +/- 0.2 versus 4.21 +/- 0.6 versus 3.91 +/- 0.5 liters/min/m2). The 15-min VPL level was 1954.5 +/- 391/ng/ml and steady state levels at Hour 24 and 120 of the infusion were 468.1 +/- 59 and 422.8 +/- 52 ng/ml, respectively. Two of 11 treatment courses resulted in hypotension secondary to inordinately high 24-h levels of VPL (1233 and 1263 ng/ml). These two episodes required inotropic support but did not require the discontinuation of VPL. There were 8 of 11 partial responses, the majority of which consisted of peripheral cytoreduction of leukemic blasts and one M-2A response in AML. The levels of VPL achieved in this study have been shown to augment the in vitro cytotoxicity of vinblastine and VP-16 to resistant cell lines. Further clinical studies are needed to determined the maximal-tolerated dose of VPL in a Phase I study and to examine its efficacy in selected relapsed pediatric patients.

The clinical characteristics of 31 patients (pts.) (17 boys, 14 girls, median age 12 11/12 years) with large cell anaplastic lymphoma (LCAL) have been evaluated. 17 of these pts. had originally been diagnosed as suffering from "malignant histiocytosis" ("MH") and were therefore included in the DAL-Histiocytosis X 83 study. Another 14 pts. with Ki-1 lymphomas were enrolled in the BFM-NHL therapy studies. According to Murphyclassification 24 pts. (77%) had stage III or IV disease and in general presented in a severe condition. The lymphatic system was involved in 28 pts., 8 pts. (26%) had skin infiltration. With regard to lymphoma involvement of lung, bones and bone-marrow were unexpectedly frequent. CNS involvement was seen in just one pt. Despite rather heterogeneous therapy approaches (ALL-schedules, DAL-HX 83 protocol for treatment of "MH", combination of B-NHL-BFM and AML-BFM schedules, CHOP, BFM protocols for B-NHL) 30 out of 31 pts. achieved clinical remission (CR). The only nonresponder died during bone marrow transplantation of septicemia. 4 pts. relapsed during therapy. 3 of them died, 1 during a BMT. 1 pt. achieved 2nd CR with a BFM-B-NHL protocol. 3 pts. experienced a late relapse, 1 died, 1 2nd CR was achieved, the third pt. is still alive after 2 further relapses disease-free for 3 years. 23 pts. (74%, 13 out of 14 of BFM-NHL therapy study, 10 out of 17 of DAL-HX 83 study, 1 pt. after BMT) are in 1st CR with a median observation time of 2 9/12 years (range 5/12 to 17 9/12 years).(ABSTRACT TRUNCATED AT 250 WORDS)

A 42-year-old woman was diagnosed as having acute myelogenous leukemia (M 2 of FAB classification) in May, 1985. Complete remission was achieved with the BHAC-DP therapy (BHAC, daunomycin and prednisolone). Whole skull irradiation and intra thecal chemotherapy were performed by way of prevention. In 1986, she developed her visual disturbance and paraplegia. Myelography and metrizamide CT indicate intraspinal and meningeal infiltration of leukemic cells in the upper thoracic spine. Leukemic cells were found in the cerebrospinal fluid but not in the bone marrow. Complete remission was obtained by irradiation and intrathecal chemotherapy. In Dec. 1986, Ommaya tubing was repeated. Hematological and neurological examinations showed no evidence of malignancy for 3 years. In Oct. 1988, she admitted to our hospital for the maintenance of the remission state, and died of sepsis. The result of autopsy revealed no leukemic cells in her CNS. It is said the intraspinal infiltration of leukemic cells is rather rare. As it is said the intrathecal injection of anti-leukemic agents is not effective for the intraspinal infiltration, irradiation should be needed. Therefore it is very important to critically differentiated intraspinal from meningeal infiltration. Furthermore, Ommaya tubing is effective in order to maintain remission in a patient with CNS leukemia.

During a 2-year period after the introduction of an intensive chemotherapeutic protocol, alpha-hemolytic streptococci accounted for 75% of all episodes of sepsis among children with acute nonlymphocytic leukemia at our institution. Only one case had occurred in the previous 8 years. Fourteen of 15 episodes of streptococcal sepsis occurred after therapy with either continuous or large dosage intermittent cytosine arabinoside. Eleven episodes occurred at two specific treatment points. Septic episodes were complicated by shock (2 of 15), encephalopathy (2 of 15), pneumonia (3 of 15) and death (1 of 15). Oral mucosal lesions may provide a portal of entry for alpha-hemolytic streptococci. These data suggest that children receiving continuous or large dosage intermittent cytosine arabinoside for treatment of acute nonlymphocytic leukemia may be at increased risk for alpha-hemolytic streptococcal sepsis. Empiric antimicrobial therapy in these children when febrile and neutropenic should include antibiotics effective against alpha-hemolytic streptococci.
