Forty-one patients with advanced renal cell cancer started treatment with recombinant alpha-interferon intramuscularly, beginning at a dose of 5 x 10(6) U x 3/week, progressively increasing doses every week, from 5 x 10(6) U x 3/week to 10 x 10(6) U x 3/week, to the highest dose of 15 x 10(6) U x 3/week. No complete response was achieved, partial response was achieved in 6 (13%) patients with a median duration of 45.2 (13-134) weeks. The majority of side effects from interferon treatment evaluated according to WHO classification were seen during the first 2 months and they were fever (after interferon administration) in 95% patients, chills (51%), flu like syndrome (65%), fatigue (87%), anorexia (80%), worsening in performance status (56%), nausea and vomiting (19%), weight loss (> 10% during therapy) (26%), leukopenia (14%), anemia (75%), neurological symptoms (43%), psychological symptoms (19%) and dyspnea (9%). The results are similar to other studies and toxicity was only moderate.

We studied the efficacy of high doses (100,000 IU intravenously (IV)/twice a week) of human recombinant erythropoietin (rHuEpo) in patients with transfusion dependent myelodysplastic syndromes (MDS). Rationale for such dose of IV Epo was the poor in vitro response of MDS erythroid progenitors (CFU-E) to physiological concentrations of Epo, and the usual high endogenous serum Epo levels of MDS patients. Seventeen patients (nine males, eight females) were included, five refractory anaemia (RA), six RA with blasts excess (RAEB), five RA with ringed sideroblasts (RARS). Tolerance was good, except in three patients who experienced severe flu-like syndrome after Epo injection. None of the patients showed hypertension or developed anti rHuEpo antibodies. Three patients (17.6%) with RAEB had 35-60% reduction of transfusion requirements. No progression of disease occurred. Percentage of erythroblasts, endogenous baseline Epo level and in vitro cultures of erythroid progenitors did not correlate with response to Epo treatment. This study shows that very high IV doses induce only seldom and partial improvement in the status of transfusion dependent MDS. This rate of response, not higher than described with lower dosage, probably represents the maximum expectable response to rHuEpo in this category of patients.

A phase II trial investigating the anti-tumour effects of recombinant human interleukin 6 (rhIL-6) in patients with metastatic renal cell cancer was carried out. RhIL-6 (150 microgram) was administered as a daily subcutaneous injection for 42 consecutive days on an outpatient basis. Forty-nine patients were studied, 12 with and 37 without previous immunotherapy. Forty patients were evaluable for response. A partial remission was noted in two patients, stable disease in 17 and progressive disease in 21. Toxicity was moderate and reversible and consisted mainly of fever, flu-like symptoms, nausea, weight loss and hepatotoxicity. Anaemia, leucocytosis and thrombocytosis and induction of acute phase protein synthesis were noted in most patients. In 15% of the patients anti-IL-6 antibodies developed, and were neutralising in only one patient. Baseline plasma IL-6 concentrations did not correlate with tumour behaviour before or after rhIL-6 treatment. In conclusion, rhIL-6 can be safely administered on an outpatient basis for prolonged period of time and has moderate, reversible toxicity. Its administration induces IL-6-antibody production in only a minority of patients. Antitmour effects of rhIL-6 in metastatic renal cancer are limited.

Recombinant human IL-6 (rhIL-6) is a pleiotropic cytokine with stimulatory actions on the hematopoietic system, the immune system and hepatocytes. Clinical interest in the use of this cytokine was raised because of its thrombopoietic properties and also because of its anti-tumor activity, which was shown in vitro and in the preclinical setting. Various studies show that doses up to 10 mu kg/kg/d rhIL-6 before and after chemotherapy are tolerable and the most frequent side-effects encountered consist of flu-like symptoms. Furthermore, a consistent decrease in hemoglobin was reported during rhIL-6 treatment. This was probably due to hemodilution, although a change in ferrokinetics, may also at least partly, explain the anemia. An evident increase of platelets has been observed in various studies. After chemotherapy, rh-IL6 seemed to hasten platelet recovery, without affecting platelet nadir. Preliminary data from studies investigating the value of rhIL-6 as an anti-tumor agent in renal cell carcinoma and melanoma reported low response rates, between 8 and 14%. The results of rhIL-6 in ameliorating chemotherapy induced bone-marrow depression and especially thrombocytopenia, are promising and merit further phase III studies.

In March 1992, March 1993, and June 1994, an international expert advisory committee oversaw a systematic and comprehensive review of potential interventions for preventing pneumonia among children aged less than 5 living in developing countries. The World Health Organization's Programme for the Control of Acute Respiratory Infections (ARIs) and the London School of Hygiene and Tropical Medicine conducted the review. There were 28 individual intervention areas identified among six broad intervention groups. Immunization comprises one of the six broad intervention categories. Specific immunization interventions include increased coverage of measles and pertussis and new vaccines for Pneumococcus, H. influenza B, respiratory syncytial virus, and other viral vaccines. Improving nutrition interventions revolve around breast feeding, low birth weight, malnutrition, vitamin A, severe anemia, and other micronutrients (e.g., zinc). The broad intervention category of reducing environmental pollution encompasses indoor air pollution, environmental tobacco smoke, and outdoor air pollution. Severely malnourished children, high risk neonates, ARI (upper tract), helminths, and wheezing fall under the case management and chemoprophylaxis intervention category. Crowding, direct transmission, and HIV are addressed in the category of reducing transmission of pathogens. The category of improving child care practices includes care-seeking, avoiding chilling, other child care practices, maternal education, and child spacing. The specialists conducted modeling to determine the potential impact of various interventions. It showed that the potential impact of an intervention increases independently with the pre-intervention prevalence of the risk category, with the size of the associated relative risk, and with the reduction in risk-category prevalence achieved by the intervention. Modeling will be used to compare the potential impacts of ARI preventive approaches with the impact achievable with the case management strategy.

The preeminent infectious threat to unwary tropical travelers, malaria is a preventable, mosquito-borne protozoan infection of red blood cells, which causes fever, anemia, respiratory failure, coma, and death. Malaria is a true medical emergency that requires rapid diagnosis and treatment. Unfortunately, in two thirds of tropical travelers who die of malaria, either treatment is delayed or the diagnosis is simply missed. Every tropical traveler with fever or unexplained, flu-like illness must be assumed to have life-threatening malaria and must have thick and thin blood smears immediately examined to confirm the diagnosis.

Two rare de novo cases are presented of pediatric erythroleukemia (EL), AML-M6 in a four-month-old (patient A) and four-year-old (patient B) African-Americans who presented to the Medical College of Georgia from 1989 to 1995. The clinical, morphologic, immunophenotypic and cytogenetic features of both patients are reviewed. The purpose of this study is to correlate the bone marrow morphology with the immunophenotypes and the karyotypes of the neoplastic cells. The patients were both female, presented with flu-like symptoms, and were noted to have hepatosplenomegaly on physical examination. The peripheral blood examination was significant for anemia (Hb 54 (A), 84(B)g/L), and thrombocytopenia (86 (A), 70(B) x 10(9)/L). The bone marrow contained 75 percent (A) and 76.8 percent (B) erythroblasts and showed myelodysplastic changes in the erythroid cell line. Cytochemical analysis was performed, and greater than 10 erythroblasts per 100 cells were periodic acid-Schiff positive. Immunophenotypes of the pretreatment bone marrow showed glycophorin-A, CD71, and CD11b positivity. The karyotypes of both patients contained complex (> 3 per clone) cytogenetic abnormalities. Our data suggest that the initial presentation and course of disease are different in adults and children. However, once the adult form reaches the acute leukemia stage, the laboratory findings are similar to those at initial presentation in pediatric EL.

The aim of this study was to determine the objective tumour response rate and duration of response and toxicity of linomide (Roquinimex) treatment in patients with disseminated renal cell carcinoma, pretreated or not pretreated with immunotherapy. From March 1991 to July 1992, 72 patients with metastatic and progressive renal cell cancer were entered of whom 9 (12%) were not evaluable for response. Linomide was given orally, twice weekly, 5 mg during the first week with dose escalation to 10 mg during the second week and 15 mg thereafter. Treatment was continued until disease progression or unacceptable toxicity. No haematological toxicity but slight anaemia was observed. A significant WBC (white blood cell count) increase (P < 0.0001, paired T-test) was found during treatment. The most often reported non-haematological side-effects were: flu-like syndrome (54%, grade III-IV 7%), nausea/vomiting (41% and 3%, respectively) and neurotoxicity (34% and 2%). Most side-effects were of mild or moderate intensity (WHO grade 1 or 2). The objective overall response rate was 4%: 1 CR and 2 PRs. Stable disease was reported for 28 patients (40%). The duration of response was 17, 22 and 30 (CR) months. Median time to progression was 5 months. Linomide at the given dose and schedule is well tolerated, but has limited antitumour activity in metastatic renal cell carcinoma.

The mechanism by which fever and influenza-like symptoms occur, after the administration of recombinant human erythropoietin (rHuEPO) to patients on continuous ambulatory peritoneal dialysis, was investigated. Peripheral blood mononuclear cells, obtained from two patients with fever and/or influenza-like symptoms related to the administration of rHuEPO for the treatment of anaemia were cultured with or without rHuEPO (100, 200, and 300 U/ml). Production of interleukin-1 beta and tumour necrosis factor-alpha was higher in cultures with rHuEPO than in cultures without rHuEPO, although the dose relationships were not clear. These findings suggest that increased production of interleukin-1 beta and tumour necrosis factor-alpha 1, induced by administration of rHuEPO, may cause fever and influenza-like symptoms.

From June 1990 to October 1994, 111 advanced ovarian cancer patients with minimal (less than 2 cm) residual disease after platinum-based front-line chemotherapy and second-look laparotomy entered a cooperative randomized study aimed at evaluating the effectiveness and the toxicity of the addition of interferon-alpha2 to carboplatin, both intraperitoneally (ip) administered. Patients were randomized to receive either 3 courses of ip Carboplatin 400 mg/m2 Day 1 q 28 days (54 pts) (CBDCA) or ip interferon-alpha 25 x 10(6) U Day 1 + ip carboplatin 400 mg/m2 Day 2 q 28 days (57 pts) (CBDCA + IFN). Patients treated with interferon experienced more severe (WHO grade 3-4) leukopenia (28% vs 17.1%) and anemia (14% vs 4.2%). Fever (P = 0.000) and flu-like syndrome (P = 0.02) were significantly more frequent in the combination arm. No difference in gastroenteric, neurologic, or renal toxicity was observed. At a median follow-up time of 13 months (range 1-72) 71 patients showed a disease progression (31 CBDCA, 40 CBDCA + IFN) and 44 patients died (21 CBDCA, 23 CBDCA + IFN). Median progression-free survival was 11 months in the CBDCA group and 10 months in the CBDCA + IFN arm. Median survival was 22 and 29 months in CBDCA and CBDCA + IFN arm, respectively. In conclusion, intraperitoneal interferon-alpha does not seem to improve the results achievable with intraperitoneal carboplatin in this subset of patients, while the toxicity and the costs of the combination are consistently higher than with chemotherapy alone.
