Angioedema with eosinophilia is classified into two types: episodic angioedema with eosinophilia (EAE), known as Gleich’s syndrome, and non-episodic angioedema with eosinophilia (NEAE). We present the case of a young lactating woman with non-episodic angioedema. She had no history of parasitic or nonparasitic infections. Physical examination showed striking, non-pitting edema in both lower extremities. Her weight had not changed significantly throughout the course of the illness. She exhibited no other symptoms, and her vital signs were normal. There was no evidence of anemia, hypoalbuminemia, thyroid dysfunction, heart failure, renal failure, or postpartum cardiomyopathy. Based on these findings, we diagnosed her with angioedema with eosinophilia. Given the scarcity of information about this condition, we explored the dynamics between cytokines/chemokines and edema in this patient. We successfully quantified the edema by bioimpedance analysis. In addition, we revealed the involvement of interleukin-5 (IL-5), thymus- and activation-regulated chemokine/C-C motif chemokine ligand-17 (TARC/CCL-17), eotaxin-3/CCL-26, tumor necrosis factor-α (TNF-α), vascular endothelial growth factor (VEGF), monocyte chemotactic protein-4/CCL-13 (MCP-4/CCL-13), eotaxin-1/CCL-11, and regulated on activation, normal T expressed and secreted/CCL-5 (RANTES/CCL-5) in NEAE. Lastly, we elucidated the strong association between these parameters. To the best of our knowledge, this is the first such study of its kind.
