Influenza

Influenza is a highly contagious, acute, febrile respiratory illness caused by influenza A and B viruses. The hallmark of these viruses is their ability to undergo rapid ongoing antigenic change and to cause annual or near-annual epidemics of febrile respiratory disease affecting all age groups. In addition, the unpredictable emergence of new influenza A subtypes can lead to explosive global pandemics of disease.

Order Zithromax Online No Prescription 250/500mg

Torsade de pointes and cardiorespiratory arrest have been reported in a patient with congenital long QT syndrome who took azithromycin. In a prospective study of 47 previously healthy people, there was a modest statistically insignificant prolongation of the QTC interval without clinical consequences after the end of a course of azithromycin 3 g/day for 5 days. Azithromycin can cause ototoxicity. In one study, 8 (17%) of 46 HIV-positive patients had probable (n = 6) or possible (n = 2) ototoxicity with azithromycin.

Specific Causes Of Acute Community-Acquired Pneumonia

Great overlap occurs among the clinical manifestations of the pathogens associated with acute community-acquired pneumonia. However, constellations of symptoms, signs, and laboratory findings serve to narrow the possibilities. By developing an ability to focus on a few pathogens or to identify a specific pathogen, clinicians can better predict the clinical course of pneumonia and can narrow antibiotic coverage. Pathogenic strains of S. pneumoniae have a thick capsule that prevents PMN binding and that blocks phagocytosis.

Anti-Infective Therapy

Despite dire warnings that we are approaching the end of the antibiotic era, the incidence of antibiotic-resistant bacteria continues to rise. The proportions of penicillin-resistant Streptococcus pneumoniae, hospital-acquired methicillin-resistant Staphylococcus aureus, and vancomycin-resistant Enterococcus strains continue to increase. Community-acquired methicillin-resistant Staphylococcus aureus is now common throughout the world.

Antimicrobial therapy: general principles

A wide variety of antimicrobial agents is available to treat established infections caused by bacteria, fungi, viruses, or parasites. This section will cover the general principles of antimicrobial therapy and will also include illustrative clinical problems to emphasize proper decision-making in using antimicrobials.

Toxicity of Antimicrobial Therapy

The mechanisms associated with common adverse reactions to antimicrobials include dose-related toxicity that occurs in a certain fraction of patients when a critical plasma concentration or total dose is exceeded, and toxicity that is unpredictable and mediated through allergic or idiosyncratic mechanisms. For example, certain classes of drugs such as the aminoglycosides are associated with dose-related toxicity.

Management of Sepsis

Sepsis, sepsis syndrome, septic shock, and multiorgan dysfunction are all part of a continuum of infection-related systemic illness. Table Definitions for Sepsis, Sepsis Syndrome, Septic Shock and Multiorgan Dysfunction Syndrome gives definitions for each of these entities. The pathogenesis of sepsis is very complex, involving a large number of mediators.

Rimantadine Hydrochloride

While the optimum dose and duration of therapy have not been established, rimantadine also has been used for the treatment of influenza A virus infection in children. While chemoprophylaxis with the drug should not be considered a substitute for annual vaccination with influenza virus vaccine, antiviral agents are an important adjunct to influenza vaccine for the control and prevention of influenza.
