Ceftaroline fosamil achieved high clinical cure and microbiological response rates in patients hospitalized with CAP of PORT risk class III or IV. Ceftaroline fosamil was well tolerated, with a safety profile that is similar to that of ceftriaxone and other cephalosporins. Ceftaroline fosamil is a promising agent for the treatment of CAP.

Community-acquired pneumonia (CAP) in adults is probably one of the infections affecting ambulatory patients for which the highest diversity of guidelines has been written worldwide. Most of them agree in that antimicrobial therapy should be initially tailored according to either the severity of the infection or the presence of comorbidities and the etiologic pathogen. Nevertheless, a great variability may be noted among the different countries in the selection of the primary choice in the antimicrobial agents, even for the cases considered as at a low-risk class. This fact may be due to the many microbial causes of CAP and specialties involved, as well as the different health-care systems effecting on the availability or cost of antibiotics. However, many countries or regions adopt some of the guidelines or design their own recommendations regardless of the local data, probably because of the scarcity of such data. This is the reason why we have developed a guideline for the initial treatment of CAP by 2002 upon the basis of several local evidences in South America (ConsenSur I). However, several issues deserve to be currently rediscussed as follows: certain clinical scores other than the Physiological Severity Index (PSI) have become more popular in clinical practice (i.e. CURB-65, CRB-65); some pathogens have emerged in the region, such as community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) and Legionella spp; new evidences on the performance of the rapid test for the etiologic diagnosis in CAP have been reported (eg. urinary Legionella and pneumococcus antigens); new therapeutic considerations needs to be approached (i.e. dosage reformulation, duration of treatment, emergence of novel antibiotics and clinical impact of combined therapy). Like in the fi rst version of the ConsenSur (ConsenSur I), the various current guidelines have helped to organize and stratify the present proposal, ConsenSur II.
