Acute eosinophilic pneumonia (AEP) is an acute respiratory illness with diffuse pulmonary infiltrates and pulmonary eosinophilia. While the etiology of AEP remains unclear, a relationship between cigarette smoking and AEP onset has been suggested. The use of heated tobacco products (HTPs) has been growing, but the impact of these products on our health is not fully understood. We herein report a case of AEP that developed after switching from conventional cigarette to HTP smoking. The patient's condition improved after the cessation of HTP smoking and corticosteroid treatment initiation. In cases of AEP, physicians should consider HTPs use as a possible cause.

A 68-year-old man visited our hospital due to anorexia, weight loss and a fever. We diagnosed the patient with disseminated Mycobacterium avium complex (MAC) and confirmed the presence of interferon (IFN)-γ neutralizing autoantibodies (IFN-γAb). His lesions improved following antibiotic therapy, but chylous ascites (CA) developed seven months after treatment. CA was able to be controlled by subcutaneous octreotide and diet therapy. IFN-γAb is recognized as having a critical role in the pathogenesis of disseminated MAC disease, but its clinical features are not fully understood. CA may be a complication that develops during the treatment of disseminated MAC infection.
