The clinical symptomatology of bacterial septicemias was analysed in 417 patients of a University Hospital in West Berlin. Sepsis was caused by Gram-negative organisms in 229 cases, and by Gram-positive bacteria in 177 cases; 11 cases presented with a mixed type sepsis involving both Gram-positive and Gram-negative pathogens. With the exception of a drop in blood pressure, observed appreciably more often in Gram-negative infections (42.4% of the cases as compared with only 25.4% in the case of septicemia due to Gram-positive organisms, (p less than 0.01), no significant clinical differences were seen between Gram-negative and Gram-positive sepsis. Pathophysiological changes (thrombopenia, leukopenia, coagulopathies) that are considered classical reactions to endotoxin, were also observed in Gram-positive infections. The overall prognosis of septicemia was determined largely by the severity of the underlying pathological condition.

Fifty-one patients with advanced non-small cell lung carcinoma were treated with a combination of mitomycin C, vinblastine and cis-platin (MVP). Most cycles were given on an out-patient basis. Major side effects were leukopenia and peripheral neurotoxicity; one patient died of sepsis while leukopenic. In 44 evaluable patients the response rate was 50%, with one complete response. Overall median survival time was 280 days and median duration of responses was 232 days. A better performance status, disease limited to one hemithorax and no prior exposure to chemotherapy positively influenced the survival. MVP is an effective chemotherapy for non-small cell lung cancer and further experience with this combination is warranted.

This retrospective study was conducted to identify the frequency of cytomegalovirus (CMV) disease in seronegative recipients of donor-specific transfusion (DST) and living-related donor (LRD) kidneys from seropositive donors. A total of 151 LRD transplants (TX) were performed at six transplant centers over a 3-year period. A total of 33 patients were identified as having been seronegative (pre-TX) for CMV, yet they had DST and a TX from a seropositive LRD. Of these patients, 12 (36.4%) seroconverted within the first 6 months post-TX and developed clinical CMV disease. Additional patients seroconverted, but did not have evidence of clinical disease and were not tested further. All TX centers, with the exception of one, had seronegative patients that became ill after receiving a seropositive DST/LRD TX. Six patients manifested their disease as a febrile illness with leukopenia and liver enzyme elevations, four had pneumonitis, and two developed CMV ulcerations of the colon (one of whom died from resultant sepsis). Of the 36 seronegative patients who received seronegative DST/LRD TX none became ill with CMV disease. Of the 72 seropositive patients who received DST/LRD TX, only 2 (2.8%) developed CMV illness (one, seropositive into seropositive, the other, seronegative into seropositive). Of the 33 seronegative patients receiving seropositive DST/LRD TX, 17 received antilymphocyte preparations (ALP), and 8 of these became ill (47.1%). Of 16 patients not receiving ALP, 5 (31.3%) developed clinical CMV illness. Of the 33 patients who were identified as having been seronegative for CMV yet received seropositive DST/LRD TX, the 12 who did develop CMV illness had two graft losses, one death, and a serum creatinine for the remaining 9 patients of 2.3 +/- 1.6 at last follow-up. The remaining 21 patients who developed no illness had a serum creatinine of 1.3 +/- 0.6 with no graft losses at the last follow-up. This evidence suggests that a prospective TX recipient who is seronegative for CMV who receives DST/LRD TX from a seropositive family member has a significant risk for developing morbidity related to clinical CMV illness.

Twenty-two patients with refractory solid tumors or lymphoma were treated with a single course of high-dose cyclophosphamide (120 mg/kg intravenously [IV] over 2 days) whereas three patients received two courses each. Marrow infusion was not used. In the 22 courses evaluable for tumor response there were 14 responses (64%) of which 11 were partial responses (PR) (50%) and three complete responses (CR) (14%). In the 12 evaluable courses given in patients with lymphoid malignancies a partial response was obtained in seven (58%) and complete response in two (17%) for an overall response rate of 75%. The median duration of response was short: 2 months (range, 1-12 months). Twenty-seven courses were evaluable for toxicity. All patients had nadir polymorphonuclear leukocytes counts less than 500/mm3 with median time to recovery to a level greater than 500/mm3 of 9 days (range, 6-21 days). The median nadir platelet count was 30,000/mm3. One patient had prolonged thrombocytopenia of 225 days. There were two toxic deaths related to leukopenia, one secondary to Pneumocystis carinii pneumonia, and the second from probable sepsis and cholecystitis. Nineteen patients had previously received cyclophosphamide in standard doses. In the patients with lymphoid malignancies who had previously received cyclophosphamide, 22% achieved a CR with an overall response rate of 78%. High-dose cyclophosphamide may be given with acceptable toxicity in heavily pretreated patients. Given the short response duration in patients with progressive disease, the optimal results of such high-dose cyclophosphamide may be achieved when it is employed earlier in the natural history of the disease in conjunction with other alkylators, or as consolidation therapy.

Low-dose continuous infusion 5-fluorouracil (LDCI-FU) was administered to 28 women with advanced breast carcinoma. Daily doses ranged from 175 to 250 mg/m2. The LDCI-FU was delivered continuously until the appearance of toxicity and was reinstituted at a 20% dose reduction after toxicity completely resolved. Patients with a median age of 56 years and a median performance status of 60% (Karnofsky) had been previously treated with combination chemotherapy. Complete responses were observed in two patients with soft tissue metastases. Thirteen patients experienced partial responses with a median duration of response of 4+ months. Partial responses were predominantly observed in soft tissue disease; however, five patients with visceral metastases experienced partial tumor regression. Median survival for the study group was 4+ months. Hormonal receptor status did not predict response to LDCI-FU. Toxicities included stomatitis, ten patients; hand-foot syndrome, eight patients; mild leukopenia, two patients; moderate thrombocytopenia, two patients; diarrhea, three patients; ataxia, three patients. Catheter-related toxicities of sepsis and/or thrombosis occurred in six patients. Because of the demonstrated activity in previously treated patients (53% response rate), LDCI-FU should be investigated in combination chemotherapy regimens in untreated breast cancer patients.

The compatibility of etoposide (VP-16-213) and cisplatin (CDDP) in an admixture solution was established by High Pressure Liquid Chromatography (HPLC) studies in vitro at room temperature. A Phase I dual-dose escalation study of the admixture was subsequently carried out utilizing a 24-hour continuous infusion schedule administered for 3 consecutive days and repeated at 3 to 4 week intervals. Twenty-seven patients received a total of 42 treatment courses. The daily dose rates for VP-16-213 were 50, 75, and 100 mg/m2/day. Cisplatin was delivered at 20, 30, and 40 mg/m2/day for each dose level of VP-16-213. Dose-rate limiting toxicity was observed first at the VP-16 dose of 50 mg/m2/day and CDDP at 30 mg/m2/day. At 100 mg/m2/day for VP-16-213, six of 17 courses were associated with life-threatening leukopenia and four of six patients died with sepsis. All but one of the patients developing severe or life-threatening leukopenia had associated acute renal failure with serum creatinine levels greater than 2 mg/dl. The optimal dose rate of delivery for VP-16 and CDDP administered as a 72-hour infusion admixture is 75 mg/m2/day and 30 mg/m2/day, respectively.

One hundred seventy-nine patients with advanced measurable colorectal cancer not previously treated with chemotherapy were entered into a prospective randomized clinical trial by the Mid-Atlantic Oncology Program (MAOP) to compare two schedules of delivery for single-agent fluorouracil (5-FU). The "standard" treatment was a schedule commonly employed in clinical practice, namely, a daily bolus dose administered intravenously (IV) for five consecutive days and repeated at 5-week intervals. The investigational treatment was a continuous infusion of 5-FU administered 24 hours a day for a protracted time (10 weeks or more). Both treatments were continued until the development of disease progression or unless interrupted for toxicity. Using stringent objective criteria requiring independent confirmation of x-ray or scan-documented response, the tumor response rate reached 7% (six of 87) for the bolus arm and 30% (26 of 87) for the infusion arms (P less than .001). Toxicity was substantially different for the two arms with major leukopenia observed only on the bolus arm, 22% developing grade 3 (severe) or grade 4 (life-threatening) leukopenia with four sepsis-related deaths. Hand-foot syndrome was observed only in the infusional arm, requiring treatment interruptions and dose reductions in 24% of patients, but with little impact on quality of life. In spite of the major difference in objective response rate, overall survival for the two groups was comparable. Administration of 5-FU as a continuous infusion for protracted periods clearly improves the therapeutic index for this agent in patients with advanced colon cancer with respect to response rate and reduced toxicity. This schedule appears workable in the community setting and yields response rates similar to those reported for 5-FU with high-dose leucovorin, but without the gastroin testinal toxicity profile of the latter combination.

Renal disease with distinctive pathologic features developed in two young women who had placental site trophoblastic tumors. The renal abnormalities were manifested by proteinuria in both cases and by hematuria in one case; blood pressure was elevated in one of the patients. Pathologic examination of the kidneys showed distinctive glomerular abnormalities, characterized mainly by the presence of occlusive eosinophilic deposits in many of the glomerular capillary lumina, most of which stained for fibrinogen-related antigens and IgM by immunohistochemical techniques. Ultrastructural examination showed the deposits to consist mainly of granular material that contained packets of fibrillar material with the appearance of fibrin. The uterine tumors were composed of mononucleated and multinucleated cells with abundant cytoplasm that infiltrated between the muscle bundles of the myometrium; in both tumors there was prominent deposition of eosinophilic material that had the tinctorial properties of fibrin and that stained for fibrinogen and IgM in immunoperoxidase studies. The renal abnormalities disappeared after hysterectomy in one case; the other patient, who was receiving chemotherapy and had disseminated intravascular coagulation, died with leukopenia and sepsis. The clinical and pathologic features in these cases suggest that the renal abnormalities were related to the uterine tumors and that the production of immune complexes and/or the activation of intravascular coagulation by the tumors were pathogenetic mechanisms.

Sixty patients with inoperable non-small-cell lung cancer (NSCLC) were entered into a phase II study that tested the combination of cisplatin (80 mg/m2, day, etoposide intravenously (IV) (100 mg, days 1 and etoposide orally (200 mg/m2, days 3 and 5). The regimen was repeated every 28 days for six courses, after which patients were allowed to receive additional treatment at the discretion of their physician. Overall objective response rate in 51 evaluable patients was 69% (95% confidence interval: range, 56% to 81%), with 16% sustaining complete remission (CR), 53% partial remission (PR), 17% stable disease (SD), and 14% progressive disease (PD). CR was pathologically confirmed by bronchoscopy and biopsy. One patient with a clinical PR underwent surgery and was shown to have a pathologic CR. Median survival of all evaluable patients was 52 weeks, greater than 75 weeks for CR patients, 52 weeks for PR patients, 42 weeks for SD patients, and 13 weeks for PD patients. Eleven patients (21.5%) developed CNS metastases, which resulted in the deaths of ten. Survival was significantly correlated with extent of disease, performance status, and albumin level, but not with histology or weight loss. Tumor response was significantly correlated only with histology (squamous-cell and large-cell undifferentiated carcinoma greater than adenocarcinoma). Side effects were nausea, vomiting, anorexia, alopecia, bone marrow suppression, and nephrotoxicity. One patient died from leukopenia and sepsis. Pharmacokinetic studies in ten patients showed the continuous presence of etoposide in plasma for six days at a level of at least 220 to 480 ng/mL. In order to investigate whether this very effective combination of cisplatin and etoposide can prolong survival in NSCLC, it will be tested as preoperative chemotherapy in a randomized trial in operable patients with T1N1 and T2N0-1 disease.

A nonhuman primate model for Argentine hemorrhagic fever has been developed that closely mimics the human clinical syndrome. Parenteral infection of adult Macaca mulatta with low-passage isolates of two Junin viral strains resulted in distinctive hemorrhagic or neurological disease in rhesus macaques that correlated with clinical illness patterns present in the humans from whom the viral strains were obtained. Transient leukopenia, together with thrombocytopenia and secondary bacterial septicemia, were documented among animals infected with both viral strains. In contrast, differing patterns of viremia, oropharyngeal viral shedding, and antibody response occurred in the two virus-infected groups. These results, together with postmortem virologic and histopathologic findings, suggest that viral-strain-specific factors are important determinants of clinical disease patterns in this model system.
