AB  - We have prospectively selected 418 patients with CAP who were treated in Health Care Centres (HCC)(mild), and hospitalized in wards (moderate) or in intensive care units (ICU) (severe) from 2001 to 2012.All of them were tested Ig serum levels using the nefelometry technique on the first day after being diagnosed with CAP. After that we compared results among the three different CAP severities (Table 1) and the frequency of mortality (Table 2).Conclusions:1.- In severe CAP patients Ig levels (IgG1, IgG2, IgG3, IgG4, IgA and IgM) decrease.2.- Having a decreased level in IgG total, IgG1, and IgG2 during a pneumonia process, is related to higher mortality.View this table:Immunoglobulin levels on the first day after CAP diagnosisView this table:Lack of Ig and mortality after 30 days
