Exercise-Induced Pulmonary Hemorrhage in a Non-Athletic Child: Implications for Military Recruits.

Hemoptysis is a rare presenting symptom in pediatric and young adult patients with a highly variable outcome ranging from an isolated mild occurrence to severe illness and death. Exercise-induced pulmonary hemorrhage (EIPH) has several reports in adult literature but has not previously been reported in pediatric patients. A 12-year-old female with a history of trisomy X (47, XXX), obesity, depression, anxiety, and obstructive sleep apnea presented to the pediatric pulmonology clinic after several episodes of hemoptysis. Spirometry, imaging, and laboratory evaluation for autoimmune vasculitides and other causes associated with pediatric hemoptysis did not reveal an etiology for the hemoptysis. A combined bronchoscopy with pediatric and adult providers revealed no airway lesions or sources of bleeding. EIPH is a diagnosis of exclusion. This patient was diagnosed with EIPH and had spontaneous resolution with improved fitness. Many military training and service activities are similar to those reported with EIPH. Trainees with various levels of aerobic fitness are at risk of developing EIPH. The hemoptysis evaluation is important for military providers given the range of severity in presentations, even though it is a rare occurrence. In addition to a novel presentation of EIPH, this case demonstrates the value of collaboration between pediatric and adult specialists in the Military Health System (MHS). Military care providers should be aware of this rare phenomenon in service members and trainees who are at risk during maximal aerobic effort.
