Etiology of Hemoptysis in Children and Adolescents – Multicentric Retrospective Data (2012-2021) From Chennai. Indian Pediatrics. 2023 Apr; 60(4): 290-2930079-60610974-7559http://imsear.searo.who.int/handle/123456789/225407Objective: To analyze the etiology of hemoptysis in children and to correlate the severity of bleed with the etiology. Methods: This retrospective multicentre study reviewed data from inpatient units of four tertiary care public and private sector pediatric hospitals in Tamil Nadu. Methods: Inpatient case records of children (aged 2 month-15 years) treated for hemoptysis at the four institutions between April, 2012 and March, 2021 were identified, after ethical clearance from respective institutions. Data of children with underlying known bleeding disorders like hemophilia or platelet abnormality were excluded from the study. Hemoptysis was categorized as mild, moderate and severe Results: Of the 73 children who had presented with hemoptysis during the study period, 60 (82.2%) children had mild, 9 (12.3%) had moderate and rest had severe hemoptysis. Idiopathic pulmonary hemorrhage was the most common cause of hemoptysis. The common causes of mild hemoptysis in children were idiopathic pulmonary hemorrhage (n=15, 25%), pulmonary tuberculosis (n=12, 20%) and pneumonia (n=8, 13.3%). Congenital airway anomalies and vascular anomalies were more likely to present with moderate to severe bleed. Conclusion: Etiology of hemoptysis is broad and categorizing them into mild, moderate and severe may give a clue about the possible etiology, there by restricting to the required investigations.BronchoscopyCongenital airway anomaliesIdiopathic pulmonary hemorrhageTuberculosisVascular anomalies.Journal ArticleIndiaApollo Children’s Hospital and Kanchi Kamakoti Child’s Trust Hospital, Chennai, Tamil NaduDepartment of Pediatrics-Operations, Mehta Multispeciality Hospitals, Chennai, Tamil NaduDepartment of Pediatrics, Institute of Child Health and Hospital for Children, Chennai, Tamil NaduDepartment of Pediatris, Government Vellore Medical College, Adukamparai, Vellore, Tamil NaduDepartment of Research and Academics Quality, Mehta Multispeciality Hospitals, Chennai, Tamil Nadu.
