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.

Serum samples from pig herds in Great Britain have been examined for antibodies to influenza virus since 1968. Antibodies to H3N2 virus strains have been found since 1968 and the serological data presented here suggests that H3N2 virus strains continue to persist in the pig population. An outbreak of acute respiratory disease occurred in a 400-sow unit. The outbreak was characterised by coughing, anorexia, fever, inappetence and loss of condition. The gilts and weaners were affected and the morbidity approached 100 per cent. An influenza A virus designated A/Swine/Weybridge/117316/86 (H1N1) was isolated from the herd and 28 paired serum samples from the affected animals showed increases in the haemagglutination inhibition titres to this isolate. Haemagglutinin and neuraminidase characterisation indicated that the virus is similar to H1N1 viruses isolated recently from pigs in Europe. A total of 91 herds experiencing respiratory disease were investigated, of which 42 gave positive reactions in the haemagglutination inhibition test. Antibodies to A/Port Chalmers/1/73 (H3N2) were also detected in some of the herds but it is not known whether this strain plays any role in the current respiratory disease problems in pigs.

Among the acquired or congenital valvular dysfunctions that require conservative valvuloplastic surgical intervention or valvular replacement, the rheumatic valve disease is reported in a limited number of cases among the developed countries, while it is frequent in those with precarious socio-economic conditions. In these countries there are many cases of rheumatic valve diseases during childhood, quickly leading to serious health conditions to require valve replacement during second and third childhood. On the contrary, in the more developed countries, congenital valvular disease prevail by far. The child who underwent valve replacement, once dismissed from cardio-surgical centre, must be nursed domiciliary by his family pediatrician. This assistance consists in a strict supervision for a precocious identification of valvular prosthesis dysfunctions and possible embolic and hemorrhagic complications and in supplying anticoagulant therapy. For this purpose it is important to refer to a well equipped cardiological centre. Besides these fundamental tasks there are others - equally important - directed to preserve health: curing each pathological extracardiac event, intercurrent or recurrent; preventing, with or without compulsory vaccinations, infectious childhood's diseases; preventing especially bacterial endocarditis as the most frequent cause of prosthesis pathology. This work pays particular attention to bacterial endocarditis (prophylaxis and cure). Thromboembolism and anticoagulant therapy (with the list of coumarin drug interventions) have also been dealt. Moreover we have reported brief indications on the prevention and/or cure of diseases for which vaccination is not compulsory, such as: measles, chicken-pox, whooping-cough, typhus, influenza. Our script ends with good suggestions on nourishment and physical activity.

The duration of immunity as measured by virological, serological and clinical responses following infection with influenza A/equine/Newmarket/79 (H3N8) was assessed in repeated challenge experiments in which ponies were infected by exposure to aerosols of infectious virus. Previous infection stimulated complete clinical protection which persisted for at least 32 weeks as demonstrated by the absence of febrile responses and coughing in two groups of ponies infected 16 weeks or 32 weeks after the first infection. Partial clinical protection persisted for over a year as demonstrated by the absence of coughing and a reduction in the number of febrile responses in a group of ponies infected 62 weeks after their first infection. These results contrasted with those observed in immunologically naive control ponies which developed pyrexia, dyspnoea and nasal discharge and coughing. The kinetics of virus specific antibody production in primary and secondary infections with equine influenza were studied by the single radial haemolysis test and a radioisotopic antiglobulin binding assay which measured virus specific IgGab antibody isotype. Antibody to the haemagglutinin, as measured by the single radial haemolysis test, declined rapidly after primary infection whereas the IgGab responses to whole virus antigens persisted for longer. The single radial haemolysis test was therefore particularly useful for the detection of antibody responses in multiple infections or exposures to influenza antigens. The radioisotopic antiglobulin binding assay was more sensitive for identifying infections which had occurred more than six months previously, as evidenced by anamnestic IgGab responses in ponies with low levels of antibody before rechallenge.

In late October 1986, an outbreak of influenza-like illness was detected at the Naval Air Station in Key West, Florida. Between October 10 and November 7, 1986, 60 active duty personnel reported experiencing a respiratory illness characterized by fever, cough, sore throat, and myalgia. Influenza A/Taiwan/1/86 (H1N1) virus was recovered from three symptomatic patients. Forty-one (68%) of 60 case-patients belonged to a 114-person squadron that had traveled to Puerto Rico for a temporary assignment from October 17-28, 1986. Among squadron members, the attack rate for persons previously vaccinated with the 1986-1987 trivalent influenza vaccine and for those unvaccinated was the same (37%). Transmission of infection among squadron personnel appeared to have commenced in Key West and continued in a barracks in Puerto Rico and aboard two DC-9 aircraft that transported the squadron back to Key West on October 28. There was no evidence that the outbreak spread to the surrounding civilian communities in Puerto Rico or Key West. This was the first reported outbreak of respiratory illness due to influenza A/Taiwan/1/86 (H1N1) in the continental United States in the 1986-1987 influenza season.

All clinical isolates of influenza A viruses from patients in Huntington, West Virginia, during the decade 1978-1988 were tested, and 65 of 65 H1N1 and 176 of 181 H3N2 viruses were susceptible to the antiviral action of amantadine and rimantadine. The five resistant viruses were obtained from three members of a family undergoing therapy or prophylaxis with rimantadine. Resistant influenza emerged during treatment with rimantadine and spread to two family contacts, causing typical influenza with fever, myalgia, and cough of 5 days' or less duration. Genetic characterization of the resistant viruses when compared to the susceptible virus isolated on day 1 from the index case revealed a single amino acid change in the transmembrane portion of the M2 protein. In vitro studies showed that rimantadine was significantly more active than amantadine against both H1N1 and H3N2 viruses. Although this resistant influenza was transmitted and caused illness in one family, the absence of naturally occurring resistant viruses suggests that the emergence of new strains of influenza A each few years may prevent the widespread emergence of resistant influenza A virus.

Tracheal mucous velocity was measured in 13 healthy non-smokers using a radioisotope-labeled aerosol and a multidetector probe during respiratory virus infections. The movement of boluses of tracheal mucous were either absent or reduced in number in five subjects with myxovirus infection (four influenza and one respiratory syncytial virus) within 48 hr of the onset of symptoms and in four subjects 1 wk later. One subject with influenza still had reduced bolus formation 12-16 wk after infection. Frequent coughing was a feature of those subjects with absent tracheal boluses. In contrast, four subjects with rhinovirus infection had normal tracheal mucous velocity at 48 hr after the onset of symptoms (4.1 +/- 1.3 mm/min). Tracheal mucous velocity was also normal (4.6 +/- 1.1 mm/min) in four subjects in whom no specific viral agent could be defined but of respiratory viral infection. During health tracheal mucous velocity was (4.8 +/- 1.6 mm/min) in the eleven subjects who had measurements made. Disturbances in tracheal mucous transport during virus infection appear to depend upon the type of virus and are most severe in influenza A and respiratory syncytial virus infection.

Chronic obstructive pulmonary disease (COPD) is equated with chronic bronchitis and emphysema as one disease entity. In COPD airflow limitation is relatively persistent--unlike asthma. Tests for "small-airways disease" form no part of routine practice, for their accuracy in detecting pathological change is debatable. The proteolytic theory of the pathogenesis of emphysema highlights the role of neutrophil elastase, antielastases, oxidants, antioxidants, and thus of potential new treatments. Clinical features of COPD include breathlessness, cough, and sputum, with airflow obstruction and lung hyperinflation. The differential diagnosis includes bronchiectasis, cystic fibrosis, and pulmonary hypertension, but pulmonary fibrosis, etc., is distinguished by radiological infiltrates. Plain chest radiography cannot reliably diagnose emphysema in life, but a new method measuring lung density from the computed tomographic (CT) scan allows location, quantitation, and diagnosis of emphysema (defined by enlargement of distal air spaces) in humans in life. "Pink puffers" with breathlessness, hyperinflation, mild hypoxemia, and a low PCO2 are contrasted with "blue bloaters" with hypoxemia, secondary polycythemia, CO2 retention, and pulmonary hypertension and cor pulmonale. Antismoking measures are a major aim in management. A bronchodilator regimen combining a slow-release oral theophylline with an inhaled beta 2-agonist, ipratropium, and high-dose inhaled steroids is proposed because even modest improvement in obstruction can help these patients. In acute exacerbations with purulent sputum, antimicrobials against Streptococcus pneumoniae and Hemophilus influenzae are used with controlled oxygen therapy aiming to keep the arterial PO2 over 50 mm Hg without the pH falling below 7.25. Influenza prophylaxis is recommended, but pneumococcal vaccination remains debatable. Chronic under-nutrition in "emphysema" implies controlled trials of feeding regimens--but these remain to be assessed. Long-term oxygen therapy is the only treatment known to prolong life in blue bloaters, and oxygen concentrators and transtracheal oxygen delivery are discussed. Pulmonary vasodilators (e.g., beta 2-agonists, hydralazine, nifedipine, angiotensin-converting enzyme [ACE] inhibitors, etc.) have not yet been proved to provide long-term reduction in pulmonary arterial pressure. Blue bloaters have severe nocturnal hypoxemia in rapid eye movement (REM) sleep that is corrected by oxygen or the investigational drug almitrine.(ABSTRACT TRUNCATED AT 400 WORDS)

To investigate the causes and clinical characteristics of acute pharyngitis among school-aged children (4 to 18 years), we obtained throat cultures for respiratory viruses, Mycoplasma pneumoniae, group A streptococcus, and Chlamydia trachomatis from 320 patients with sore throat and 308 controls without respiratory complaints. The study was conducted from January to April 1985 in a private pediatric practice in central New York State. Sixty percent of the patients and 26% of the control subjects had positive cultures for at least one organism. Forty percent of patients had positive cultures for group A streptococcus, compared with 11.9% of the controls. Fifty (16%) patients had positive viral cultures, compared with eight (2.6%) controls; the predominant viral isolate was influenza A Philippines. Patients infected with influenza A were significantly more likely to complain of cough and hoarseness, and were less likely to have pharyngeal exudate or tender cervical adenopathy, than were patients who had positive cultures for group A streptococcus. Although 49 (15.8%) patients with acute pharyngitis had cultures positive for M. pneumoniae, 53 (17.6%) asymptomatic controls were also had M. pneumoniae-positive cultures. Thus detection of M. pneumoniae in the throat of school-aged children with pharyngitis may not be sufficient to establish a diagnosis of disease caused by this organism. C. trachomatis was not isolated from any patient or control.

The spread of influenza virus through a community typically causes large increases in medical visits for febrile respiratory disease. Increased school absenteeism occurs early in the epidemic, and school children appear to be important for disseminating the virus. Industrial absenteeism, hospitalizations of adults and infants for pneumonia, and deaths due to pneumonia-influenza all tend to peak later in the epidemic. Although influenza infection rates are highest in persons of school age, hospitalizations and deaths occur primarily in infants and in the elderly, particularly among those with pulmonary, cardiovascular, or other debilitating disorders. Influenza viruses can be spread by aerosol or contact. The primary target cells are those of the respiratory epithelium. In healthy adults, the typical influenza syndrome includes fever, cough, and general aches for three to seven days, but lassitude, cough, and evidence of small-airways disease may persist for weeks. Laryngotracheobronchitis, pneumonia, and unexplained fever are prominent manifestations of influenza that lead to hospitalization of young children. Adults are more likely to have complications of bacterial pneumonia and worsening of chronic pulmonary disease or congestive heart failure. Less frequent complications include myositis, various neurologic disorders, and Reye's syndrome. These consequences of influenza clearly justify strenuous efforts at prevention and control.
