According to a cross-sectional study conducted at Dr. Susheela Tiwari Hospital, Government Medical College, Haldwani, tubercular pleural effusion accounted for 45% of pediatric pleural effusion cases admitted to the tertiary care facility. Researchers evaluated 80 children to determine clinical profiles, etiological patterns, and in-hospital outcomes, finding that infectious diseases dominated diagnoses while pleural fluid adenosine deaminase offered significant diagnostic utility.
Infectious Etiologies Dominate Pediatric Pleural Effusion Diagnoses
Tubercular pleural effusion emerged as the leading diagnosis in 36 of the 80 children, representing 45% of the study cohort. Parapneumonic effusion followed as the second most common cause in 18 patients (22.5%), while empyema thoracis accounted for 11 children (13.75%). Cough and fever served as the primary clinical warnings, appearing in 85% and 77.5% of patients respectively.
Diagnostic Performance of Pleural Fluid Adenosine Deaminase
Researchers relied on a comprehensive diagnostic framework combining clinical examinations, radiological imaging, and biochemical analyses to identify underlying causes. Pleural fluid adenosine deaminase (ADA) demonstrated strong diagnostic performance for detecting tubercular pleural effusion, with mean levels reaching 84 ± 22 IU/L in tubercular cases compared to 43 ± 19 IU/L in non-tubercular cases. Receiver operating characteristic curve analysis revealed an area under the curve of 0.84, with a 40 IU/L threshold yielding a sensitivity of 83.3% and a specificity of 77.3%.
Did you know? While 36 children were diagnosed with tubercular pleural effusion, only 12 cases were confirmed microbiologically via cartridge-based nucleic acid amplification testing. The remaining 24 patients were diagnosed using a composite clinico-radiological and biochemical definition.

Frequently Asked Questions
What are the primary symptoms of pleural effusion in children?
The predominant symptoms recorded in the Haldwani study were cough (85%), fever (77.5%), and dyspnea (67.5%), alongside clinical signs such as decreased breath sounds and tachypnea.
How common is tuberculosis as a cause of pediatric pleural effusion?
In this tertiary-care study from India, tuberculosis accounted for 45% of all pediatric pleural effusion cases, making it the single most frequent etiology.
What role does ultrasound play in diagnosing pleural effusions?
Ultrasonography helps detect free versus loculated effusions, identifies septations, and guides safe diagnostic or therapeutic pleural taps.
