Introduction Pneumonia is inflammation of the lung that is most often caused by infection with bacteria, viruses, or other organisms. Occasionally, inhaled chemicals that irritate the lungs can cause pneumonia. Healthy people can usually fight off pneumonia infections. However, people who are sick, including those who are recovering from the flu (influenza) or an upper respiratory illness, have a weakened immune system. This makes it easier for bacteria to grow in their lungs. It is one of the top 10 causes of death in the U.S. and the 6th leading cause of death in the elderly (65 and older). Defining Pneumonia by Location in the Lung Pneumonia may be defined according to its location in the lung: Lobar pneumonia occurs in one part, or lobe, of the lung. Bronchopneumonia tends to be scattered throughout the lung. Defining Pneumonia by Origin of Infection Doctors often classify pneumonia based on where the disease is contracted. This helps predict which organisms are most likely responsible f...
A recent article in the NY Times addressed the link between the use of PPI's and pneumonia. The study, which was published in The Journal of the American Medical Association, indicated that those on PPI medications had 30% greater the risk of developing hospital acquired pneumonias than the group not taking PPI's ( 1 ). The study showed no increase for those taking the medications Zantac or Prilosec. The New York Times article talked with a couple of physicians who noted that PPI use could limit the amount of coughing a person does, and that the lack of coughing could increase the risk for pneumonia. Another theory was that the PPI use could increase the growth of certain bacteria, because the acid was not present to kill those bacteria, and that could be responsible for the increase in pneumonia. There was no mention made of whether those who are on PPI's, due to having conditions such as GERD, might have been at a greater risk for pneumonia to begin with. ...
Anaerobic pneumonia; Aspiration of vomitus; Necrotizing pneumonia; Aspiration pneumonitis
Some people may need to be hospitalized. Treatment depends on the severity of the pneumonia . You may receive antibiotics, which treat bacteria. Some people may get special antibiotics to treat bacteria that live in the mouth.
The type of bacteria that caused the pneumonia depends on:
Where you live (at home or in a long-term nursing facility, for example)
Whether you've recently been hospitalized
Recent antibiotic use
You may need to have your swallowing function tested. Patients who have trouble swallowing may need to use other feeding methods to reduce the risk of aspiration.
The outcome depends on:
The severity of the pneumonia
The type of bacteria causing the pneumonia
How much of the lungs are involved
If acute respirator...
