Influenza infections

The use of antibiotics is not recommended, except for the treatment of infectious exacerbations of COPD and other bacterial infections. Influenza vaccines decrease illness and death in COPD patients. Pneumococcal vaccination is also recommended.

Lamotrigine has been nsed as maintenance monotherapy for rapid-cycling bipolar disorder in 324 patients (open label) and 182 patients (donble-bUnd) with rapidcycling bipolar disorder (5). In aU, 265 patients reported adverse events during the open phase. The most common adverse events (over 10%) were headache, infection, influenza, nausea, abnormal dreams, dizziness, and rash. During the donble-bUnd phase 122 patients reported adverse events, eqnaUy with lamotrigine and placebo.

Examples of common clinical situations in which nonsurgical antimicrobial prophylaxis is effective are given in Table 51-4. Nonsurgical prophylaxis, mentioned in earlier chapters, includes the prevention of CMV and HIV infections, influenza, meningococcal infections, and tuberculosis. Though somewhat less effective, antimicrobial prophylaxis is also commonly used for animal or human bite wounds and chronic bronchitis. Severely leukopenic patients are often given prophylactic antibiotics. 

HHS Action Plan to Prevent Healthcare-Associated Infections Influenza Vaccination of Healthcare Personnel describes an initiative of the Department of Health and Human Services (HHS) to improve vaccination rates for influenza among healthcare workers. 

Influenza. The ACIP recommends annual influenza vaccination for all persons who are at risk from infections of the lower respiratory tract and for all older persons. Influen2a vimses types A and B are responsible for periodic outbreaks of febrile respiratory disease. 

This fusogenic activity of influenza hemagglutinin is frequently exploited in the laboratory. If, for example, the virus is bound to cells at a temperature too low for endocytosis and then the pH of the external medium is lowered, the hemagglutinin causes direct fusion of the viral envelope with the plasma membrane infection is achieved without endocytosis. Similarly, artificial vesicles with hemagglutinin in their membrane and other molecules in their lumen can be caused to fuse with cells by first allowing the vesicles to bind to the plasma membrane via the hemagglutinin and then lowering the pH of the medium. In this way the contents of the vesicles are delivered to the recipient cell s cytoplasm. 

The sources for this type of control are infectious hospital or clinic patients, w here the infection can be transmitted through the airborne route. The most common application is for control of the spread of tuberculosis, but it could be used for other airborne infections such as varicella or influenza. -... 

Amantadine is an antiviral agent that is active against influenza A infection and against some strains of H5NX avian flu. Draw a three-dimensional representation of amantadine showing the chair cyclohexane rings. 

There are a number of practical problems involved with using polysaccharides as vaccines as there are frequently too many different chemotypes for it to be practicable to prepare a vaccine. In some cases a limited number of serotypes are the dominant cause of infection and it may then be possible to produce vaccines. A major problem is the poor immune response elicited by polysaccharide antigens, which may in some cases be improved by chemical modification. This is (fie case for vaccines for Haemophilus influenzae type b (a causative agent of meningitis), where the antigenicity of the polysaccharide can be increased by coupling to proteins. 

A large and rapidly growing number of clinical trials (phase I and phase II) evaluating the potential of DNA vaccines to treat and prevent a variety of human diseases are currently being performed ( http // clinicaltrials.gov) however, there is yet no licensed DNA vaccine product available for use in humans. The clinical trials include the treatment of various types of cancers (e.g., melanoma, breast, renal, lymphoma, prostate, and pancreas) and also the prevention and therapy of infectious diseases (e.g., HIV/ABDS, malaria, Hepatitis B vims, Influenza vims, and Dengue vims). So far, no principally adverse effects have been reported from these trials. The main challenge for the development of DNA vaccines for use in humans is to improve the rather weak potency. DNA vaccines are already commercially available for veterinary medicine for prevention of West Nile Vims infections in horses and Infectious Hematopoetic Necrosis Vims in Salmon. 

Neuraminidase inhibitors are the major class of drugs to treat or to prevent the infection with influenza viruses. Currently, two neuraminidase inhibitors are available, zanamivir and oseltamivir, which block the release of new influenza vims from infected host cells and thereby stop the spread of infection. The enzyme neuraminidase is a surface glycoprotein present on all influenza viruses. There are nine influenza neuraminidase sub-types known of which subtypes N1 and N2 appear to be the most important ones. Neuraminidase inhibitors are effective against all neuraminidase subtypes. The activity of the neuraminidase is required for the newly... 

Meropenem (Merrem IV) inhibits syndiesis of die bacterial cell wall and causes die deadi of susceptible cells. This drug is used for intra-abdominal infections caused by Pseudomonas aeruginosa, Escherichia coli, Klebsiella pneumoniae, and odier susceptible organisms Meropenem also is effective against bacterial meningitis caused by Neisseria meningitidis, Streptococcus pneumoniae, and Hemophilus influenzae. 

Myositis may also have an infective basis. Viral myositis has been recorded in association with influenza and picomavirus infections, particularly those due to viruses of the Coxsackie group, and HIV infection is an increasingly common cause of myositis seen in routine practice. Fungal, bacterial, and parasitic myositis is seen much more rarely in North America and Europe than in tropical parts of the world, but in these regions these forms of infective myositis constitute a significant problem. In any survey of inflammatory muscle disorders, it is also necessary to consider other inflammatory conditions which affect muscle indirectly, but do not cause myositis in the strict sense of the word. In this group are to be found various forms of arteritis and fascitis and granulomatous conditions such as sarcoidosis.
