[A patient with allergic bronchopulmonary candidiasis showing a high serum level of soluble interleukin 2 receptors].

An 84-year-old man was admitted to Yonezawa City Hospital with fever, cough, hemoptysis and progressive dyspnea. He had complained of wheezing asthmatoid and exertional dyspnea for the previous 10 years, regardless of the season. On admission, chest radiographs revealed a diffuse ground-glass shadow, fibrotic change, and volume reduction. Arterial blood gas analysis showed extreme hypoxemia. A computed tomographic (CT) scan of the chest showed not only faint ground-glass opacities and dense patches in the whole lung field, but also central bronchiectasis. Laboratory tests revealed that both total serum levels of IgE and specific IgE for Candida albicans were elevated. In the bronchoalveolar lavage fluid, lymphocyte, neutrophil and eosinophil percentages were high, and the CD4/CD8 ratio was low. We diagnosed the fibrotic stage of allergic bronchopulmonary candidiasis. During treatment with hydrocortisone and fluconazole, eosinophilia in the peripheral blood was observed, and serum candida antigen was positive. In addition, high serum levels of soluble interleukin 2 receptors were observed in this patient.
