Diagnóstico y tratamiento empírico de la neumonía adquirida en la comunidad en situaciones especiales: pacientes inmunocomprometidos sin infección por el VIH y ancianos

In the elderly, pneumonia often has a less florid clinical presentation and is frequently complicated by decompensation of concomitant diseases. Elderly patients have special characteristics in terms of the pathogens involved in pneumonia; they are at greater risk of multiresistant bacterial infections because of their frequent contact with the health services. Lung infections in immunosuppressed individuals have different causes depending on the immune deficiency in question. Admission to hospital or ambulatory treatment will be decided after stratifying the risk; this treatment will be determined by the characteristics at the time of onset of the pneumonia, the local epidemiological situation in terms of the percentage of antibiotic resistance in the area, and the clinical particularities.
