The notion of tissue neutropenia due to impaired signal transduction secondary to decreased newborn neutrophil membrane receptor mobility allows intervention to improve neutrophil mobilization. New pharmacologic agents and biologic response modifiers show promise of increasing the newborn neutrophil's ability to respond to chemotactic signals. This approach will lead to the development of effective adjuvant therapy for neonatal sepsis.

From 1984 to 1987 two consecutive groups of juvenile cancer patients (n = 45) with fever and neutropenia corresponding in all criteria were examined. In half of the total of 90 febrile episodes and septicemias, a conventional antibiotic combination therapy (Pseudomonas-active penicillin/cephalosporin of the third generation/aminoglycoside) was instituted. In the remaining half imipenem was used as an antibiotic monoagent. In 66% and 60% of the febrile episodes treated with antibiotic combination therapy and with imipenem, respectively, septicemia was confirmed by positive blood cultures. Nineteen febrile episodes occurred in the myeloaplastic phase after bone marrow transplantation. In a comparative study of imipenem as monotherapy versus an antibiotic combination therapy the results obtained with imipenem were superior in many regards. No resistance developed necessitating change of antibiotic therapy. Coagulase-negative Staphylococci, primarily responsible for catheter-associated septicemia, were susceptible. Duration of fever and thus duration of treatment were shorter. The incidence of side effects and costs were lower. Therefore, imipenem as an antibiotic monotherapy in febrile cancer patients with neutropenia appears to be more efficacious than the conventional combination therapy, even during myeloaplasia following bone marrow transplantation. The results and rationale of this retrospective analysis are discussed.

We conducted a prospective, randomized trial to study the efficacy and tolerance of long-term versus short-term treatment with recombinant interferon alfa-2a in patients with chronic hepatitis B. Ten patients were randomly assigned to a 6-month interferon regimen, and 10 patients were assigned to a 3-week interferon trial. Eleven patients (five assigned to long-term treatment and six to short-term treatment) did not complete interferon therapy: eight had either severe thrombocytopenia or neutropenia; one had pronounced fatigue in relationship to administration of interferon; one had spontaneous bacterial peritonitis and sepsis and died; and one had a massive fatal variceal hemorrhage during interferon therapy. Most of the serious hematologic complications occurred in patients with cirrhosis and hypersplenism. In one patient, seroconversion to hepatitis B virus DNA negativity occurred before the onset of treatment. Four of the five patients able to complete the 6-month interferon regimen and only one of four patients able to complete the 3-week trial had seroconversion to hepatitis B virus DNA negativity. Thus, we conclude that the therapeutic response was better among patients who were able to complete a 6-month interferon trial. In patients with cirrhosis and hypersplenism, development of either severe thrombocytopenia or leukopenia associated with interferon therapy precluded completion of treatment.

Ten previously untreated patients with gastric cancer were treated with etoposide, 120 mg/m2 intravenously (i.v.) on days 4, 5, and 6, Adriamycin, 20 mg/m2 i.v. on days 1 and 7, and cisplatin, 40 mg/m2 i.v. on days 2 and 8 (EAP). Etoposide, 240 mg/m2 on days 4, 5, and 6, was administered orally instead of intravenously in alternating cycles, and pharmacokinetic studies were performed in those who had previously undergone gastrectomy or who had tumor infiltrating the stomach to determine oral bioavailability. Nine patients had advanced measurable gastric cancer, and one patient had an elevated carcinoembryonic antigen after surgery for synchronous gastric and colon cancer. The median age was 54 years (range 38-69), and the median Eastern Cooperative Oncology Group (ECOG) performance status was 2 (range 0-3). Nine of 10 patients had poorly differentiated adenocarcinoma. Twenty-four cycles were administered to 10 patients, and hematologic data were available for 23 courses. ECOG grade 4 neutropenia and thrombocytopenia developed in 19 (83%) and 8 (53%) courses, respectively. Thirteen courses (54%) were complicated by fever requiring parenteral antibiotics. Two patients (20%) died due to neutropenic sepsis. The profound myelotoxicity observed in our study prompted us to terminate the investigation prior to completing accrual. The oral bioavailability of etoposide was 21% and 36% in the two patients who had had prior gastrectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Severe infection is a major cause of morbidity and mortality in patients with malignancy. In this study, 34 episodes of septicemia occurred in 1,468 childhood patients with malignancy who admitted and were treated at National Sapporo Hospital between 1979 and 1988. The occurrence of septicemia and its mortality rate were higher in malignant hematologic disease than in malignant solid tumor. Most cases of septicemia occurred in relapse. The most frequent organism causing septicemia were Klebsiella pneumoniae (16.3%) and Staphylococcus epidermidis (16.3%). Septicemia due to Gram-negative organism was more frequent than that of Gram-positive organism or fungus. Polymicrobic septicemia occurred 3 times and multiple episodes 6 times. They had a high mortality rate. Neutropenia was strongly associated with episode of septicemia. In our series, absolute neutrophil count under 500 per microliter developed septicemia. Especially, children with less than 100 granulocytes per microliter had a major risk factor for the development of infection and death. No children with granulocyte count greater than 1000 per microliter died in connection with septicemia.

Between October 1985 and January 1989, 33 patients with stage I (31) or clinically occult stage II (2) endometrial cancer at a high risk for recurrence were entered in a prospective study evaluating adjuvant cisplatin, doxorubicin, and cyclophosphamide (PAC) chemotherapy. Eligibility criteria included grade 2 tumors with middle- or outer-third myometrial invasion (16), grade 3 tumors with any degree of myometrial invasion (17), presence of extrauterine disease with no gross residual (17), or a high-risk histologic subtype including papillary serous (4), adenosquamous (5), or clear cell (1) tumors. Patients received PAC (50/50/500 mg/m2) at 4-week intervals for six cycles. Thirty patients (90%) completed therapy. Toxicity included severe neutropenia in 14 patients, neutropenic sepsis in 2 patients, and doxorubicin-related cardiomyopathy in 1 patient. There were no treatment deaths. Current median follow-up is 25 months. Nine patients (27%) have developed a recurrence, 7 of whom died, after a median interval of 14 months. Eight of the 9 with recurrence initially had extrauterine disease (P = 0.02). The resulting 2-year actuarial progression-free and overall survival rates were 79 and 83%, respectively. The median progression-free interval was 29 months for patients with extrauterine disease and 45+ months for those with no extrauterine disease (P = 0.02). These results suggest that a phase 3 randomized trial comparing adjuvant PAC with radiation therapy is warranted.

We performed clinicopathological studies on early-onset sepsis (5 infants, less than 72 hours of life, EOS) and late-onset sepsis (15 infants, greater than 72 hours, LOS) of very low birth weight, less than 1500 g (VLBW). In EOS, the clinical features mimic the respiratory distress syndrome and hematological changes were not observed. The lungs showed slight interstitial pneumonia with structural immaturity, hyaline membranes, hemorrhage, and minimal infiltration by polymorphonuclear neutrophils (PMNs). The pathogen was group B streptococcus or weakly gram-negative bacilli. In LOS, pneumonia proceeded to sepsis and neutropenia with elevated numbers of circulating immature neutrophils, and increased levels of C-reactive protein were observed at the onset of sepsis. Severe pneumonia with infiltration of numerous PMNs and bacterial colonies and polymicrobial infection by nosocomial pathogens such as Staphylococcus aureus and Pseudomonas aeruginosa were common. The thymus and spleen weights varied but retained normal structure in EOS. The thymus was depleted of lymphocytes, and the spleen was hypertrophic but poorly reactive against infection in LOS. The pathogenesis of EOS is regarded as being more closely correlated with lung immaturity and circulatory disorder in early life, whereas that of LOS is associated with immunological defenses of the host, potency of the pathogens, and terminal multiple organ failure.

We report a patient with the syndrome of large granular lymphocytes in whom the initial clinical features were polyarthritis, hepatosplenomegaly and neutropenia. Relative lymphocytosis was also demonstrated at the expense of a subpopulation with morphology and surface markers characteristic of large granular lymphocytes (CD2+, CD8+, CD16+ and HNK-1+). After 6 months of asymptomatic course, without changes in clinical or laboratory data, the patient died from an acute abdomen with mesenteric ischemia of different likely causes as suggested by necropsy data (multivisceral diffuse infiltrate by large granular lymphocytes, systemic vasculitis and Clostridium sepsis). The association between this syndrome and systemic vasculitis is discussed.

23 newly diagnosed patients affected by cutaneous T-cell lymphoma were treated with sub-cutaneous interferon alpha-2a to evaluate the therapeutic efficacy and the toxicity of this agent. IFN was administered daily with dose escalation from 3 to 18 million units for 12 weeks; thereafter, patients induced into complete (CR) or partial (PR) remission were given IFN at maximal tolerated dose 3 times weekly for 6 or 9 months. The objective tumor response was observed in 17 patients (74%): 8 (35%) were CR and 9 (39%) were PR. A 74-yr-old patient died because of neutropenia and sepsis at the end of induction phase, while receiving IFN at dose of 18 million units. Disease stage is the initial feature predictive of response to IFN therapy. The dose schedule of this study was well tolerated: only 3 patients developed liver toxicity, while leukopenia was evident in 6 patients. Only 2 CR patients have relapsed, 18 and 24 months from response; the remaining 6 CR patients are in continuous complete remission with a median follow-up of 41.8 months. 6 PR patients have progressed from 8 to 17 months after response, and in the 3 PR patients not yet progressed the response duration ranges from 20 to 24 months. In conclusion, interferon alpha-2a is a very effective agent in therapy of untreated cutaneous T-cell lymphoma with an overall response rate of 74%.

One hundred five patients receiving concurrent aminoglycoside and vancomycin therapy of at least 5 days' duration were retrospectively reviewed for development of nephrotoxicity. All had their vancomycin and aminoglycoside serum concentrations controlled by a clinical pharmacokinetics service. Nephrotoxicity occurred in 28 (27%) of the patients. Twenty-two of the 28 had other factors that are known to contribute to renal failure (amphotericin B therapy, sepsis, liver disease, obstructive uropathy, pancreatitis, anesthesia). The remaining six developed nephrotoxicity without other known contributing factors. Logistic regression analysis revealed associations between nephrotoxicity and age, sex, aminoglycoside trough and vancomycin peak and trough serum concentrations, length of aminoglycoside and vancomycin therapy, concurrent amphotericin B therapy, liver disease, neutropenia, and peritonitis (p less than 0.05). In addition to factors previously reported, this study found that neutropenia and peritonitis are associated with an increased risk of nephrotoxicity. Patients with one or more risk factors warrant close monitoring of renal function as well as vancomycin and aminoglycoside serum concentrations.
