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 being studied. For example, the incidence of pleural effusion among ICU patients is estimated to be 22.19 ± 17%,[3] whereas 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 effusions is constantly increasing, although, 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 the most frequent cause followed by S. pneumoniae. The age predominace of pleural effusion varies depending on the underlying cause. 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] HIV infection,[4] pleural empyema, and complicated parapneumonic effusion is mostly seen in middle-aged patients (53 ± 17 years).[8] Males are more commonly affected with tuberculous pleural effusion than females. The male to female ratio is approximately 3:2.[4] Males are more commonly affected with pleural empyema and complicated parapneumonic pleural effusion than females. The male to female ratio is approximately 2:1.[8] There is no racial predilection to pleural effusion. Development of tuberculous pleural effusion is common on endemic developing countries with TB infection.[4]

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 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 the most frequent cause followed by S. pneumoniae.

Age

The age predominace of pleural effusion varies depending on the underlying cause as shown 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 females. The male to female ratio is approximately 3:2.[4]
  • Males are more commonly affected with pleural empyema and complicated parapneumonic pleural effusion than females. The male to female ratio is approximately 2:1[8]

Race

  • There is no racial predilection to pleural effusion.

Developed/developing countries

  • Development of tuberculous pleural effusion is common on endemic developing countries with TB infection.[4]
