Meningococcal sepsis with cardiovascular manifestations is one of the leading causes of pediatric intensive care admission (14.85%) in our area. We carried out a two phase study over period of 10 years from 1979 to 1988, involving a retrospective analysis of clinical and analytical manifestations in order to determine a prognostic score of the severity of meningococcal infections in our area. A total of 86 cases were studies over a two year period. After establishing the prognostic score, we applied a previously assayed therapeutic protocol, based on the number of criteria of severity, in 170 children selected as having the same criteria. The factors of seriousness considered were: Appearance of the first symptoms less than 12 h. previously, appearance of petechia less than 6 h. previously, hyperthermia, shock at admission, absence of meningitis, fulminating course of purpura and convulsions, leukopenia less than or equal to 5,000 mm3, prothrombin activity less than or equal to 45%, platelets less than or equal to 75,000 mm3, fibrinogen less than or equal to 250 mgrs% and FPD greater than 40 micrograms/ml (p less than or equal to 0.01 (CHI SQUARE]. In the first phase of study, overall mortality was associated with the presence of three criteria, and was highest when more than seven criteria were present. The results indicate that mortality from meningococcal sepsis is linked to fulminating deterioration of hemodynamics and DIC.(ABSTRACT TRUNCATED AT 250 WORDS)

Silver sulfadiazine cream (SSD) has been used successfully in the management of burn wound sepsis. Silver deposition has been found in the skin, gingiva, cornea, liver, and kidney of patients treated with this cream, causing argyria, ocular injury, leukopenia, and toxicity in kidney, liver, and neurologic tissues. Monitoring concentrations of silver in blood and urine of patients receiving this treatment has become necessary, but sensitive and suitable methods adaptable to a clinical laboratory are still needed. We have developed a flameless thermal atomic absorption spectrophotometric method to measure silver concentrations in blood, urine, and other tissues. The detection limit is 0.4 microgram/L; the within-run precisions (CV) are 5.16%, 3.83%, and 2.79% for concentrations of 5, 13.5, and 42 micrograms/L, respectively; and the between-run precisions are 4.3% and 3.2% for concentrations of 13.5 and 42 micrograms/L. The concentrations of silver in blood, urine, liver, and kidney of subjects without industrial or medicinal exposure are less than 2.3 micrograms/L, 2 micrograms/day, 0.05 microgram/g wet tissue, and 0.05 microgram/g wet tissue, respectively. In SSD cream-treated burn patients, plasma concentrations may be as great as 50 micrograms/L within 6 h of treatment and can reach a maximum of 310 micrograms/L. Silver in urine is detectable after one day of treatment and may reach a maximum of 400 micrograms/day. After absorption, silver was found to be deposited in various tissues. Tissue silver concentrations in one burn patient who died of renal failure after eight days of treatment were 970, 14, and 0.2 micrograms/g wet tissue in cornea, liver, and kidney, respectively.

23 cases of drug-induced blood disorders were reported from 7 hospitals in Chugoku district. These cases were treated between Oct 1982 and Jun 1990. These included 5 cases of anemia, 2 cases of leukopenia, 6 cases of thrombocytopenia, 1 case of anemia and leukopenia, 2 cases of anemia and thrombocytopenia, and 1 case of leukopenia and thrombocytopenia. There was a case of methemoglobinemia due to Sedes-G. A patient of agranulocytosis due to cimetidine died of sepsis. The all other patients recovered. The reported drugs which induced blood disorders were analgesics, anticonvulsant agent, chemotherapeutic agent, antituberculosis agent, and H2 receptor blockade, etc. in order of number. The drugs in 3 cases were definitely thought to be the cause of blood disorders, probably in 18 cases, and possibly in 2 cases.

Five of 23 patients with recurrent nasopharyngeal carcinoma (NPC) were diagnosed to have bone marrow metastasis. They all had advanced local-regional disease, and were treated with neoadjuvant chemotherapy and definitive radiotherapy after the initial diagnosis. Bone marrow metastasis developed 4-24 months later. The clinical features were anemia (5 of 5), leukopenia (3 of 5), thrombocytopenia (4 of 5), sepsis (3 of 5), tenderness of the sternum (3 of 5), and fever (4 of 5). Patients frequently had elevation of serum lactic dehydrogenase (LDH), alkaline phosphatase (ALK-P), and IgG and IgA antibody titers to Epstein-Barr viral capsid antigen when bone marrow involvement was diagnosed. However, clinical manifestations and laboratory tests were not specific. It is important that three patients had normal bone scans. All five patients had a rapid downhill course; four patients died within 23 days, and the fifth 3 months after the diagnosis of bone marrow metastasis. We concluded that bone marrow was a common metastatic site in NPC patients. Bone marrow metastasis adversely affected patients' survival and required a high index of suspicion for diagnosis. We suggested that bone marrow biopsy should be considered as a routine staging procedure in NPC patients and indicated especially when patients presented with abnormal blood counts, sepsis, bone pain, or tenderness of the sternum. It may be positive in the face of a normal bone scan.

The existence of the overwhelming postsplenectomy infection syndrome in adults after traumatic splenectomy is controversial. Due to the similarity of the porcine immune system to man we chose the pig to study subsets of peripheral mononuclear cells after splenectomy and resistance to experimental Pneumococcal infection after splenic surgery and specific immunization. Female miniature pigs were assigned to four operative groups: sham operation, splenectomy, splenic resection, and heterotopic splenic autotransplantation. Hematologic and flow cytometric analysis of mononuclear cells and their subsets revealed a marked leukocytosis following splenectomy and autotransplantation but no significant shift in monocyte and B-cell numbers. Response of leukocytes to septicemia, bacterial elimination from peripheral blood, and mortality were not affected by splenectomy or spleen-preserving operations. Mortality of splenectomized animals was 18%, compared to 42% in sham-operated controls (difference not significant). Immunization protected animals from development of leukopenia, and led to an enhanced bacterial elimination, and a significantly decreased mortality of 5%, compared to 48% in nonimmune animals. Thus our data do not show significant effects of splenectomy on subsets of porcine mononuclear cells or on resistance to experimental Pneumococcal septicemia.

A total of 44 patients with infiltrating, locally advanced bladder cancer (stages T 3a-b, T 4a-b and N+/N0) were treated with the systemic chemotherapy regimen of cisplatin, methotrexate and vinblastine (CMV) in the neoadjuvant setting, of whom 39 were evaluable for response. After planned radical cystectomy and 2 to 3 cycles of chemotherapy no tumor was found on the pathological specimen of 4 patients (10%), the tumor was downstaged in 19 (49%) and no change was observed in 16 (41%). Toxicity included leukopenia in 29 patients (66%), 1 of whom died of granulocytopenic sepsis, nausea and vomiting in 39 (89%) and mild to moderate mucositis in 18 (41%). Median followup is 12 months with a range of 6 to 39 months. Of 32 patients followed for longer than 6 months 6 (19%) experienced progression or recurrence of disease. We conclude that preoperative CMV chemotherapy is effective in inducing downstaging of the tumor, although systemic toxicity limits its use to cautiously selected patients.

In order to elucidate a possible role of hypercoagulability leading to disseminated intravascular coagulation (DIC) in the pathogenesis of multiple organ failure (MOF), unfractionated heparin and the related agents were administered to septic rabbits which manifest DIC and MOF. Administration of heparin resulted in prevention of thrombocytopenia, leukopenia and elevation of plasma bilirubin and creatinine. The morphological hepatic damage was also ameliorated by heparin. Similar favorable effects were obtained by the administration of low molecular weight heparin. Dextran sulfate prevented the hepatic damage to some extent without improvement on other parameters. No significant effect was observed by the administration of a synthetic thrombin inhibitor (MD805). These results indicate that the favorable effect of heparin is due to its anticoagulant property, especially anti-Xa activity. Thereby, it is concluded that the hypercoagulable state leading to DIC is a prerequisite for the occurrence of MOF in sepsis.

In vitro studies have documented the synergistic antiviral and antiproliferative activity of recombinant interferon alpha (rIFN alpha) and rIFN gamma. Furthermore, rIFN gamma is a strong immunomodulator with optimal effects at a relative low dose (0.1 mg/m2). On the basis of these observations, we began a phase I/II study with the combination of rIFN gamma at 100 micrograms/m2 (2 x 10(6) IU/m2) and rIFN alpha 2c 6 micrograms/m2 (2 x 10(6) IU/m2), injected twice a week subcutaneously. In cases of stable or progressive disease we increased the dose of rIFN alpha 2c every 2 weeks by 6 micrograms/m2 until the maximum tolerated dose was reached. A total of 32 patients with proven progressive renal-cell carcinoma were included. Of the 31 eligible patients, 21 were male and 10 female, their average age was 57.2 years (range 35-72), 28 had had nephrectomy, their median Karnofsky performance status was 90% (70%-100%), and their tumors were localized predominantly to visceral tissue. In 2, response was complete and in 6 it was partial, for a response rate of 25%. The disease had stabilized in 5 patients and progressed in 16. The median duration of partial response was 14 months (8-16 months); of 2 cases of complete response, 1 persists (23+ months), and the other suffered a relapse after 22 months. The median time to response was 24 weeks (18-24 weeks). The maximum tolerated dose of rIFN alpha was 30 micrograms/m2 (range of 6-36 micrograms/m2). Side-effects included those known to be associated with interferon treatment. One patient developed septicemia during a period with grade 4 leukopenia. Our study permits no conclusion regarding the additional value of rIFN gamma.

Endotoxemia was evoked by bolus injection of Escherichia coli endotoxin (2 ng/kg body weight) in six healthy subjects to investigate the early kinetics of cytokine release in relation to the development of clinical and hematologic abnormalities frequently seen in gram-negative septicemia. The plasma concentration of tumor necrosis factor (TNF) increased markedly after 30 to 45 minutes, and reached a maximal level after 60 to 90 minutes. In each volunteer, the initial increase of plasma interleukin 6 (IL-6) concentrations occurred 15 minutes after the initial TNF increase, and maximal IL-6 concentrations were reached at 120 to 150 minutes. A transient increase in body temperature and pulse rate occurred simultaneously with the initial TNF and IL-6 increases, whereas a significant decrease in blood pressure occurred after 120 minutes. These changes were proportional to the changes in TNF and IL-6 concentrations. Coagulation activation, as assessed by a rise of prothrombin fragments and thrombin-antithrombin III complexes, was noted after 120 minutes, in the absence of activation of the contact system. A two- to sixfold increase in the concentrations of tissue plasminogen activator (t-PA) and von Willebrand factor antigen indicated endothelial cell activation. This increase started at 120 and 90 minutes, respectively. The release of t-PA coincided with activation of the fibrinolytic pathway, as measured by plasmin-alpha 2-antiplasmin complexes. The fibrinolytic activity of t-PA was subsequently offset by release of plasminogen activator inhibitor, observed 150 minutes after the endotoxin injection, and reaching a peak at 240 minutes. No complement activation was detected. These results show that in humans endotoxin induces an early, rapidly counteracted fibrinolytic response, and a more long-lasting activation of thrombin by a mechanism other than contact system activation. In addition, our data suggest that endotoxin-induced leukopenia and endothelial cell activation are mediated by TNF.

A total of 25 patients with locally advanced bladder cancer, staged T3 and T4, have received neo-adjuvant VMC chemotherapy with Vinblastine, Methotrexate and Cisplatinum. The evaluable patients were 21 and after cystectomy demonstrated the following responses: pCR in one case (4%), pRP in ten cases (48%), pNC in 10 patients (48%). Toxicity was mainly represented by leukopenia in 18 patients (82%), one of them died from neutropenic sepsis. After a median follow-up time of 12 months (range 6-39) 5 patients already experienced relapse of the disease.
