OBJECTIVE: This study aimed to analyze the anemia characteristics in early pregnancy of pregnant women with hemoglobin H (Hb H) disease and their pregnancy outcomes, and to provide reference to the pregnancy management and treatment of these women. PATIENTS AND METHODS: Twenty-eight cases of pregnant women who had been diagnosed with Hb H disease in the Second Affiliated Hospital of Guangxi Medical University from August 2018 to March 2022 were retrospectively analyzed. Moreover, 28 cases of normal pregnant women in the same period were randomly enrolled as a control group for comparison. The means and percentages of the anemia characteristics in early pregnancy and the pregnancy outcomes were calculated and the analysis of variance, Chi-square test, and Fisher's exact test were applied for comparison. RESULTS: A total of 13 cases of missing type (46.43%) and 15 cases of non-missing type (53.57%) were observed in the 28 cases of pregnant women with Hb H disease. The genotypes were as follows: 8 cases of -α3.7/--SEA (28.57%), 4 cases of -α4.2/--SEA (14.29%), 1 case of -α4.2/--THAI (3.57%), 9 cases of αCSα/--SEA (32.14%), 5 cases of αWSα/--SEA (17.86%), and 1 case of αQSα/--SEA (3.57%). Twenty-seven patients with Hb H disease (96.43%) were anemic, including 5 cases of mild anemia (17.86%), 18 cases of moderate anemia (64.28%), 4 cases of severe anemia (14.29%), and 1 case of non-anemia (3.57%). Compared with the control group, the Hb H group had significantly higher red blood c...
