Clinical manifestations of lymphocytic choriomeningitis (LCM) virus infection in 15 patients are described. These patients were University Hospital personnel who had had contact with hamsters, subsequently shown to harbor the virus. Fever with striking myalgias, headache and rigors were the most common symptoms. Only 2 of the 15 patients had clinically overt and documented aseptic meningitis. Leuikpenia was observed in 10 of 11 patients and thrombocytopenia in 8 of 8 patients tested. A biphasic illness was seen in eight patients. In a patient who has been exposed to laboratory animals, particularly to hamsters, a nonspecific influenza-like febrile illness accompanied by leukopenia and thrombocytopenia may represent LCM virus infection.

Difluorodeoxycytidine (dFdC) demonstrated broad spectrum activity in preclinical models. A phase 1 study utilizing twice weekly injections was conducted in 50 eligible and evaluable patients. Twenty-nine patients received drug by 30 minute infusion at doses of 5-90 mg/m2 and 22, by 5 minute bolus at 30-150 mg/m2. The primary dose limiting toxicities were marrow suppression and flu-like symptomatology. Thrombocytopenia was dose limiting at 75 mg/m2 on the infusion schedule and 150 mg/m2 on the 5 minute schedule. Flu-like symptoms with fever, rigors and malaise occurred the day of injection in many patients. One patient with renal cell carcinoma attained a partial response. Evaluation of the drug's efficacy and schedule dependency continue.

Twenty-two evaluable patients with advanced adenocarcinoma of the pancreas, but without prior chemotherapy or immunotherapy, received recombinant tumor necrosis factor (rTNF). rTNF was given as an intravenous infusion over 30 min daily x 5, every 14 days, at a starting dose of 150 micrograms/m2/day. Toxicities included fevers/rigors, nausea/vomiting/anorexia, flu-like symptoms, hypotension, hyperglycemia, anemia, coagulopathy, hepatotoxicity, and hypertriglyceridemia. Laboratory evidence of disseminated intravascular coagulopathy occurred in 11 patients, with only 3 of these patients having clinical manifestations. Two patients suffered from pulmonary emboli. The high incidence of coagulopathy was felt to be, at least in part, disease related. No objective responses were observed with a 95% confidence interval of 0-15%.

Fifty evaluable patients with advanced colorectal cancer, but without prior chemotherapy or immunotherapy, were randomized to one of two schedules of recombinant gamma-interferon (rGIFN). Twenty-four evaluable patients received rGIFN as a 2-h intravenous infusion daily x 5 every other week at a starting dose of 4.0 x 10(6) IU/m2/day (arm I). Twenty-six evaluable patients received rGIFN as a 24-h continuous intravenous infusion daily x 5 every month at a starting dose of 2.6 x 10(6) IU/m2/day (arm II). Toxicities on both schedules included flu-like symptoms, fevers/rigors, nausea/vomiting, hypotension, leukopenia, hepatotoxicity, nephrotoxicity, diarrhea, anemia, confusion, and ileus. Toxicity appeared to be more severe on arm I. No antitumor responses were observed, with 95% confidence intervals of 0 to 14% for arm I and 0 to 13% for arm II.

Concomitant pneumonia and influenza constitute the leading infectious cause of death in the elderly and the fourth most common cause of death overall. The presence of concomitant illness and delays in diagnosis contribute to significant mortality from this disease in the elderly; senescence of the immune system seems less important in predisposition to pneumonia than the presence of concomitant illness. Delay in diagnosis is frequently secondary to the atypical presentations of pneumonia in the elderly. The usual symptoms of fever, chills, rigors, and sputum production that are present in young adults all may be absent; confusion may be the only presenting symptom. Tachypnea is frequent, but the physical examination, in addition to often being technically difficult, is not sufficiently sensitive in making a diagnosis. Leukocytosis is common, but by no means specific. Chest roentgenograms frequently show incomplete consolidation and findings are difficult to distinguish from other diseases of the elderly, such as congestive heart failure, atelectasis, pulmonary embolism, and malignancy. Therefore, clinical diagnosis requires a high index of suspicion despite atypical clinical manifestations.

The toxicity, pharmacokinetics, and hematologic effects of granulocyte-macrophage colony-stimulating (GM-CSF) were studied in a phase I/II trial of 16 patients with myelodysplastic syndrome (MDS). The GM-CSF was administered subcutaneously (SC) daily so as to achieve prolonged blood levels and to establish an outpatient treatment regimen. Four dose levels were administered for ten days: 0.3 microgram/kg/d (three patients), 1.0 microgram/kg/d (three), 3.0 micrograms/kg/d (four), and 10.0 micrograms/kg/d (six). The most common toxicities were fever and a flu-like syndrome, which were dose-dependent. The maximum-tolerated dose was 10.0 micrograms/kg/d, which induced severe rigors (two patients), fever greater than 40 degrees C (one), severe bronchospasm (one), and WBC 60,000 (one). In one patient, refractory anemia with excess blasts in transformation (RAEB-T) progressed to acute nonlymphocytic leukemia after two doses of GM-CSF, and the patient died of leukemia that did not respond to chemotherapy. After doses of 3.0 and 10.0 micrograms/kg, serum GM-CSF levels peaked at 3.8 to 6.3 hours, and persisted for 14 and 24 hours, respectively. Circulating granulocytes (neutrophils and bands) increased in a dose-dependent manner, as 11 of 13 patients who received greater than or equal to 1.0 microgram/kg/d responded with a two- to 194-fold increase. Although the neutrophils usually returned to pretreatment levels shortly after stopping GM-CSF, two patients continue to exhibit an elevation of neutrophils for 6 months. Dose-related increases in circulating monocytes and eosinophils were also noted. Transient increases in platelet and reticulocyte counts were observed in two and three patients, respectively. Five of the 16 patients later received maintenance GM-CSF at 3 micrograms/kg/d for 2 to 9 weeks. All showed a dramatic increase in neutrophils after 2 weeks. Thereafter, despite continued therapy, the neutrophil count in four patients declined markedly. In conclusion, GM-CSF is well tolerated by the SC route and induces striking, but usually temporary, improvement in the neutropenia of MDS. Larger prospective phase III trials will determine the duration of hematologic responses and the impact on infection, morbidity, and mortality.

A principal side effect of biological response modifiers (BRMs) is a constellation of constitutional symptoms often referred to as a "flu-like syndrome" (FLS). Precisely what this syndrome encompasses is frequently unclear, but its major components appear to be fever, chills, rigors, myalgias, and headache. Other components variously included are anorexia, nausea, upper respiratory symptoms such as nasal congestion and cough, and the ill-defined symptom, malaise. The manner in which the "flu-like" syndrome manifests itself during treatment with interferon (IFN), interleukin-2 (IL-2), tumor necrosis factor (TNF), monoclonal antibodies (MoAbs), and colony stimulating factors (CSFs) will be described with attention to frequency, duration and severity. The common mechanisms underlying the appearance of a flu-like syndrome during biotherapy will be elucidated with emphasis on the role of endogenous pyrogens and prostaglandins and on the physiology of the process. Methods to prevent or alleviate these uncomfortable side effects, including medical interventions such as alterations in schedule/route/dose of BRM administration and premedication with a variety of agents, as well as nursing measures such as patient education will be discussed.

The incidence of influenza, influenza-like illness and the common cold during the influenza epidemics of 1972 and 1976 as reported to the weekly returns service of the Royal College of General Practitioners was examined by three regional areas and by age group. The results of a postal questionnaire concerned with diagnostic criteria used by participating doctors were also analysed. These two analyses were used to explore the validity of these diagnostic terms as reported in the weekly returns service.The two influenza epidemics peaked at about the same time throughout the country and in all age groups simultaneously, although the severity of the epidemic seemed to wane from south to north in 1976. The reported incidence of influenza-like illness and of the common cold was less in the central region than in the north and south during both the two epidemic years. Influenza incidence was maximal in age groups 15-44 and 45-64 years, whereas the reported incidence of influenza-like illness and the common cold was maximal in pre-school children.Additionally, influenza-like illness and the common cold appeared to a fairly uniform extent every winter whereas influenza was truly epidemic.From the questionnaire to general practitioners, the symptoms of rigors, malaise and myalgia and the recognition of an epidemic were the important criteria which differentiated influenza from influenza-like illness.We conclude that in general practice the distinction between influenza and influenza-like illness is reliably made and has validity in the clinical context and meaning of these diagnostic terms.

Because two of five patients with renal cell carcinoma in a Phase I study had partial response to recombinant alpha-2 interferon (IFN), we treated 26 patients with advanced renal cell carcinoma with a 3-month regimen of IFN. Patients were randomized to receive IFN either subcutaneously (2 X 10(6) IU/m2 3 times a week) or intravenously (3 X 10(7) IU/m2 for 5 consecutive days every 2-3 weeks). Patients whose disease was responding or stable were treated further, while those with progressive disease on subcutaneous treatment were offered intravenous therapy. Sites of metastasis included lung (14 patients), bone (7 patients), soft tissue (7 patients) and liver (2 patients). Twenty patients were evaluable for response. One patient had a partial response at the end of the third course of intravenous IFN and subsequently had complete disappearance of a 12 X 7 cm subcutaneous mass after the seventh course of treatment. The disease was stable in 13 patients including two minor responses, and six patients had progressive disease (5 with subcutaneous treatment; 1 with intravenous treatment) including one mixed response. All patients experienced early flu-like symptoms of fever, chills, and rigors during the first few days of treatment and most had mild to moderate fatigue. Three patients left the study because of fatigue, and one had an urticarial rash. From these results and our previous experience, it appears that IFN has activity against renal cell carcinoma with acceptable toxicity.

This study was designed to evaluate the clinical tolerance to multiple IM injections of rDNA-produced human alpha-2 interferon (IFN) (Schering-Plough 30500) in patients with solid tumours. IFN was administered in escalating IM doses in separate groups of patients daily for 14 days and then twice weekly for a further 10 weeks. The dosage levels were 1, 3, 10, and 30 million U/injection. Subjective toxicity could be divided into two types, acute and chronic. The acute reactions took the form of an influenza-like syndrome consisting in chills, rigors, headache, tremor, nausea, vomiting, and myalgia. These symptoms were dose-related but tachyphylaxis developed with continued dosing. The chronic toxicity consisted of malaise, lethargy, fatigue, anorexia, and confusion. These symptoms were not so dose-dependent and tended to become more severe with prolonged treatment. Objective toxicity consisted of myelosuppression and liver dysfunction. Granulocyte counts below 1.0 X 10(9)/l were seen in three patients at the 30-million-U level, with platelet counts less than 100 X 10(9)/l in two of these. Elevation of the liver enzymes were seen in all five patients treated at 30 million U, but returned to normal after 1 week without IFN in all but one patient. A tolerable dose (IM) for phase II/III studies lies between 3 and 10 million U for daily scheduling and between 10 and 30 million U for twice-weekly injections.
