Background
Hemophilia A (HA) is an x-chromosome-related recessive disorder caused by a defect in the coagulation factor VIII gene, and timely and proper treatment can improve the quality of life of patients.
Objectives
Summarize the epidemiology, disease characteristics, and treatment of single-center HA patients in real-world China.
Methods
A retrospective analysis of 662 patients with HA in the Second Hospital of Shanxi Medical University was performed, and the basic information of the patients was summarized using descriptive statistics, and the differences between groups were compared using ANOVA, and the geographical distribution characteristics of patients with HA in Shanxi Province were introduced using heat maps.
Results
662 patients with HA were registered at our center. Most patients had single status, low employment rates, and low educational levels. 85.3% had a moderate to severe HA, 13% had mild HA. Of these, 20.5% of the patients had an active inhibitor. The intron 22 inversion was the most common genetic mutation, accounting for 53.7% of severe HA patients. The joints and muscles were the most common bleeding sites, with 55.1% of the patients having target joints. The mean diagnostic delay time between mild and severe HA was statistically significant (p < 0.01). Regarding treatment, 43.5% of the patients were on prophylactic treatment, usually 2–3 times a week.
Conclusions
Based on the real data of a single center in China, this study shows the realistic situation of Chinese HA patients and has certain clinical significance, and better treatment measures to improve the quality of life of HA patients should be explored in the future.
