Respiratory infections upper

Local host defenses of both the upper and lower respiratory tract, along with the anatomy of the airways, are important in preventing infection. Upper respiratory defenses include the mucodliary apparatus of the nasopharynx, nasal hair, normal bacterial flora, IgA antibodies, and complement. Local host defenses of the lower respiratory tract include cough, mucodliary apparatus of the trachea and bronchi, antibodies (IgA, IgM, and IgG), complement, and alveolar macrophages. Mucus lines the cells of the respiratory tract, forming a protective barrier for the cells. This minimizes the ability of organisms to attach to the cells and initiate the infectious process. The squamous epithelial cells of the upper respiratory tract are not ciliated, but those of the columnar epithelium of the lower tract are. The cilia beat in a uniform fashion upward, moving particles up and out of the lower respiratory tract.

The indications for these agents are in principle identical to those of the non-selective NSAIDs although the substances have not yet received approval for the whole spectrum of indications of the conventional NSAIDs. Because they lack COX-1-inhibiting properties, COX-2-selective inhibitors show fewer side effects than conventional NSAIDs. However, they are not free of side effects because COX-2 has physiological functions that are blocked by the COX-2 inhibitors. The most frequently observed side effects are infections of the upper respiratory tract, diarrhoea, dyspepsia, abdominal discomfort and headache. Peripheral oedema is as frequent as with conventional NSAIDs. The frequency of gastrointestinal complications is approximately half that observed with conventional NSAIDs. 

Vitamin C status is supposed to play a role in immune function and to influence the progression of some chronic degenerative diseases like atherosclerosis, cancer, cataracts, and osteoporosis. The role of vitamin C in immune function, especially during common cold and upper respiratory tract infection, is the subject of lively debate. The exact mechanisms of action have not yet been fully elucidated, but the results of several trials point to a reduced duration and intensity of infections in subjects consuming high amounts of vitamin C (200-1000 mg/d). However, the incidence of common cold was not influenced significantly (24).

Human viruses will cause disease in other animals. Some are capable of infecting only a few closely related primate species, others will infect a wide range of mammals. Under the conditions of natural infection vimses generally exhibit a considerable degree of tissue specificity. The influenza vims, for example, replicates only in the cells lining the upper respiratory tract.

Infections of the respiratory tract are among the commonest of infections, and account for much consultation in general practice and a high percentage of acute hospital admissions. They are divided into infections of the upper respiratory tract, involving the ears, throat, nasal sinuses and the trachea, and the lower respiratory tract (LRT), where they affect the airways, lungs and pleura. 

This is an acute, non-invasive infectious disease associated with the upper respiratory tract (Chapter 4). The incubation period is fiom 2 to 5 days although the disease remains communicable for up to 4 weeks. A low molecular weight toxin is produced which affects myocardium, nervous and adrenal tissues. Death results in 3-5% of infected children. Diphtheria immunization protects by stimulating the production of an antitoxin. This antitoxin will protect against the disease but not against infection of the respiratory...

CrCl greater than or equal to 30 to less than 50 mL/minute) and severe (CrCl less than 30 mL/minute) renal impairment respectively. Renal function monitoring is recommended prior to initiation and periodically thereafter. Adverse events in clinical trials included nasopharyngitis (5.2%), upper respiratory tract infection (6.3%), and headache (5.1%). Currently, no significant drug interactions are known. 

The most common adverse effect with omalizumab is injection-site reaction, reported in 45% of patients in clinical trials. Other adverse effects include viral and upper respiratory tract infections, sinusitis, headache, and pharyngitis. Rare cases of malignant neoplasms and anaphylaxis were reported during clinical trials of omalizumab in asthma. Patients should be monitored for at least 2 hours following the injection so that anaphylaxis and/or injection-site reactions may be managed.25...
