Overview
In the United States, up to one million patients develop parapneumonic effusions annually, and approximately 100,000 patients undergo pleurodesis for recurrent pleural effusions per year.[1] Pleural effusion is reported to have an incidence of 0.32% in a study among the general population in central Bohemia. Congestive heart failure accounts for nearly 50% of cases, with malignancy, pneumonia and pulmonary emboli as the next three leading causes.[2] However, the distribution of causes is largely dependent on the population studied.
Epidemiology and Demographics
Incidence and prevalence
In the United States, up to one million patients develop parapneumonic effusions annually, and approximately 100,000 patients undergo pleurodesis for recurrent pleural effusions per year.[1] Pleural effusion is reported to have an incidence of 0.32% in a study among the general population in central Bohemia. Congestive heart failure accounts for nearly 50% of cases, with malignancy, pneumonia and pulmonary emboli as the next three leading causes.[2] However, the distribution of causes is largely dependent on the population studied.
The incidence of pleural effusion among ICU patients is estimated to be 22.19 +/- 17%.[3]
Tuberculosis is one of the most frequent causes of pleural effusion. Although the incidence has steadily declined in some countries (4.8 cases/100,000 population), the prevalence of tuberculous pleural effusion remains steady with respect to the total number of TB cases (14.3%-19.3%).[4]
The incidence of parapneumonic pleural effusions is constantly increasing although by definition they are considered to be a "parapneumonic" phenomenon, the microbial epidemiology of these effusions differs from pneumonia with a higher prevalence of anaerobic bacteria.[5]
The incidence of pediatric empyema increased from 1 per 100 000 children aged 0 to 14 years in 1998 to 10 per 100 000 in 2012, with a peak incidence of 13 per 100 000 in 2009[6] with Staphylococcus aureus as most frequent cause followed by S. pneumoniae.
Age
The age predominace of pleural effusion varies depending on the underlying cause as show below:
- Greater than 60% of tuberculous pleural effusion commonly affects individuals between 15-44 years.[4]
- Pleural effusions are the most common thoracic involvement findings in patients with POEMS syndrome, affecting more than 40% of cases with median age at the time of diagnosis of POEMS syndrome as 45.1 years.[7]
Gender
Males are more commonly affected with tuberculous pleural effusion than female. The male to female ratio is approximately 3:2.[4]
