Patient's question:
Child, one year and five months old, suddenly developed low fever on October 29, 2018, and coughed for over a week. His face was pale and yellow. After a thorough examination at the city children's hospital, he was diagnosed with pulmonary hemosiderosis. He was hospitalized for 18 days. Do the doctors know how to treat this disease? Please reply urgently. Thank you very much.Doctor's answer:
Hemosiderin-laden cold agglutinin disease is a disease with an unknown cause. Its inflammatory characteristic is alveolar capillary hemorrhage, where hemoglobin is compressed and stored in the form of hemosiderin in the interstitial space of the alveoli, ultimately leading to pulmonary fibrosis. The onset age is primarily in childhood, with most cases occurring in infants and preschool-aged children. The pathogenesis may be related to autoimmune mechanisms, but the specific mechanisms remain unclear. The disease has a long course, with recurrent episodes, and carries a poor long-term prognosis.
