Abstract： Objective:To improve the awareness of hyper-IgE syndrome (HIES) characterized by disseminated infection.Methods:We retrospectively analyzed a patient with HIES characterized by Talaromyces marneffei and Staphylococcus aureus mixed disseminated infection in Shenzhen People′s Hospital. The clinical manifestations, results of laboratory tests/genetic examinations, therapeutic strategies and prognosis were summarized. The keywords “hyper-lgE syndrome” were used to search and review the literature in Wanfang databases and Pubmed database. Results:In February 2021, an 18-year-old male patient was admitted to our hospital with backache for over 3 weeks and fever for 4 days. Physical examination revealed deciduous teeth in the oral cavity, bilateral renal pain on percussion, and interphalangeal joint hyperextension. Laboratory studies demonstrated increased blood eosinophils and serum level of total IgE. Bacterial culture from bronchoscopic secretions, bronchial mucosa, and necrotic tissue from the left upper arm showed Talaromyces marneffei. Bacterial culture from alveolar lavage fluid, left upper arm necrotic tissue, puncture fluid of right retroauricular abscess and renal drainage fluid suggested methicillin-sensitive Staphylococcus aureus. The chest and abdominal CT revealed diffuse patchy and nodular lesions in bilateral lungs, cavitary lesions in the upper lobe of the left lung, multiple enlarged lymph nodes in the mediastinum, and infectious lesions within both kidneys and perirenal space. Furthermore, the patients was identified with STAT3 mutations by whole exome sequencing, which confirmed the diagnosis of HIES. Nineteen literature articles were retrieved, involving 27 adult patients with a median age of diagnosis of 23 years. The most common manifestations included: skin infection (16/27), eczema (15/27), elevated IgE (26/27) and eosinophils (17/27), as well as positive STAT3 mutation (11/27). Conclusion:Clinicians should be alert to the possibility of hyper-IgE syndrome in patients with severe or disseminated intracellular bacterial infections.
