[Criteria for treating MRSA in sputum]. / Kriterien zur Behandlung von MRSA im Sputum?

ABSTRACT

Methicillin-resistant strains of Staphylococcus aureus (MRSA) are of particular significance for the management of patients with airway infections, since the disease course is often complicated and treatment rendered difficult by multiple resistance. Their prevalence is now slowly declining, but still alarmingly high. Hospital-acquired infections are predominant, but hospital-associated and community-acquired infections do occur, as do rare infections with livestock-acquired strains. Non-nosocomial strains are characterized by different pathogenic factors and a different spectrum of antibacterial resistance; they often have a threatening disease course. Anti-infectives with activity against MRSA are unusual and have particular toxicity profiles. On the other hand, MRSA colonization is eliminated spontaneously in healthy people and acute bronchitis is treatable by common oral antibiotics. However, chronic airway infection in bronchiectasis and other forms of structural airway damage requires a complex systemic and local treatment approach for pathogen elimination.
