| Zusammenfassung: | Objective: To summarize the clinical characteristics of two families with hereditary angioedema in children. Methods: A retrospective analysis was conducted on the general information, clinical manifestations, genetic variations, and laboratory test results of two families diagnosed with hereditary angioedema at Department of Rheumatology and Immunology, Shenzhen Children's Hospital from December 2022 to May 2023. And using keywords such as "children" "adolescent" "infant" "toddler" "pediatric" "hereditary angioedema" search for relevant literature from VIP, Wanfang, CNKI, PubMed, Web of Science and Google Scholar from the establishment of the database until January 2024 and summarize the diagnosis and clinical characteristics of hereditary angioed in children. Results: Case 1, female, 12 years old, presented with intermittent abdominal pain for 8 years, aggravated with vomiting for 2 days. Eight years ago, without a clear cause, case 1 experienced abdominal pain and underwent two abdominal surgeries. The concentration of C1 esterase inhibitor was 0.46 g/L, and the function of C1 esterase inhibitor was less than 0.01. The SERPING1 gene had a c.1396C>G variation, and she was diagnosed with hereditary angioedema type Ⅱ. Among the other 13 family members, 8 had swelling in different parts, and 2 had died. Case 2, female, 17 years old, was diagnosed with hereditary angioedema type Ⅰ due to intermittent limb swelling for more than 2 years. She had C4 of 0.09 g/L, C1 esterase inhibitor concentration of 0.05 g/L, C1 esterase inhibitor function <0.01, SERPING1 gene c.882C>G variation. Two out of the other 12 family members experienced intermittent skin swelling. Literature review meets the search criteria with 0 Chinese literature and 15 English literature, including a total of 524 cases of hereditary angioedema in children. Combined with 2 families in this group, there are 5 families with hereditary angioedema in children as the proband. The onset time is 1-15 years old, and the diagnosis delay time is -0.9 to 20.0 years. Two hundred and sixty-three cases (50.2%) of the children had a family history survey, of which 229 cases (87.1%) had a positive family history. Two hundred and fifty-seven cases (49.0%) had clear disease classification, with type Ⅰ being the main type, accounting for 234 cases (91.1%). The clinical symptoms of 296 children (56.5%) were described in detail, including 262 cases (88.5%) with skin edema in different parts, 176 cases (59.5%) with abdominal pain, and 61 cases (20.6%) with upper respiratory tract edema in the throat. Conclusions: Hereditary angioedema is mainly characterized by episodic skin and mucosal swelling, with individualized differences in the locations and characteristics of the onset. Hereditary angioedema in children is often overlooked, and patients with a positive family history of episodic skin and mucosal swelling need to actively undergo complement level testing |
