Resumen
LOLI-AUSEJO, David; VILCHEZ-SANCHEZ, Francisca y TOMAS-PEREZ, Margarita. Girl with hypersensitivity pneumonitis. A case report. Rev. alerg. Méx. [online]. 2021, vol.68, n.1, pp.84-88. Epub 30-Ago-2021. ISSN 2448-9190. https://doi.org/10.29262/ram.v68i1.844.
Background:
Hypersensitivity pneumonitis entails several inflammatory lung diseases that preferentially affect the alveolar and perialveolar tissue. It is a very rare disease in children, with a complicated diagnosis due to the fact that antigen exposure usually goes unnoticed.
Case report:
A 12-year-old girl with dry cough, dyspnea, wheezing, and tachypnea, with partial improvement after treatment with inhaled bronchodilators and corticoids. The spirometry showed a restrictive pattern and reduced lung diffusion capacity; in the CT scan, centrilobular ground-glass opacities were observed, and a lymphocyte count of CD4/CD8 of 2.46 (lymphocytosis) was obtained from the bronchoalveolar lavage. IgG positivity to bird feathers was obtained.
Conclusions:
The treatment of hypersensitivity pneumonitis is based on avoiding exposure to the causative agent, which is determined by the prognosis; for which taking an extensive medical history is of paramount importance. Corticosteroids can be prescribed based on the clinical response, the pulmonary function, and the radiological improvement.
