Study Summary

480 pregnant patients diagnosed of silent or standard α-thalassemia, HbH disease, minor or intermediate β-thalassemia with mild anemia will be randomly assigned to treatment group and control group. Patients in the treatment group will be given 15 g of Colla corii asini powder form daily for 8 weeks and followed up to 42 days postpartum while the control group will be observed and followed up in the same period treated with placebo. Levels of hemoglobin(Hb), reticulocyte (RET), immaturity reticulocyte (IRF), indirect bilirubin(IBIL), total bilirubin(TBIL), lactic dehydrogenase(LDH) will be measured on three visits(baseline, week 4 and week 8). The curative effect of TCM Syndrome( week 8) and undesirable pregnancy outcomes(42 days after giving birth) will be observed.

Study Description

Thalassemia is a type of hemolytic anemia disease caused by genetic defect of synthesis in one or more globin chains. Among all the single genetic disorders thalassemia has the highest incidence rate in the world and causes heavy burdens on public health system. In China, the southern provinces suffer from high incidence of thalassemia, which is particularly common in the population of Guangdong, Guangxi and Yunnan provinces. Epidemiological studies showed that in Guangdong alone about 17.83 % of the 14,332 pregnant women across 21 regions examined were diagnosed as carriers of thalassemia .

Recent studies showed that compared with healthy controls, women with thalassemia are associated with a wide range of abnormality and adverse pregnancy outcomes including cardiovascular disease, thrombotic disease, spontaneous miscarriage, premature delivery, oligohydramnios, fetal growth restriction and low birth weight. Currently there is no consensus on treating anemia in pregnant thalassemia patients. Due to the absence of an safe and effective therapeutic measures, many thalassemia patients are prone to develop low level of Hb, which can severely impact the fetal growth and maternal health.

In traditional Chinese medicine (TCM), Colla corii asini (CCA, E'jiao) is a gelatin-like traditional Chinese medicine refined from donkey hide and has been widely used in clinical antanemic therapy for more than 2000 years. In the last decade, many studies had addressed the effect of CCA on the anemia using modern pharmacological approaches. The results indicated that CCA contains collagen protein,glycogen and a variety of trace elements, a variety of amino acids, etc. the main components of CCA can promote hematopoiesis by a number of mechanisms which eventually increase the peripheral erythrocyte counts and Hb concentration. Therefore, the investigators proposed that the hematopoietic effects of CCA might also contribute to the treatment of thalassemia with insuffcient or abnormal Hb concentration.

The study aims to evaluate the efficacy and safety of Colla corii asini (CCA ) in improve anemia during pregnancy among silent or standard α-thalassemia, HbH disease, minor or intermediate β-thalassemia. Four hundred and eighty pregnant patients who meet inclusion criteria will be randomly assigned to either the treatment group or control group. Patients in the treatment group will be given 15 g of CCA daily for 8 weeks and followed up to 42 days postpartum, while the control group were observed and followed up in the same period treated with placebo. Levels of hemoglobin (Hb),reticulocyte (RET), immaturity reticulocyte (IRF), indirect bilirubin (IBIL), total bilirubin (TBIL), lactic dehydrogenase (LDH) will be measured on three visits (baseline, week 4 and week 8). The curative effect of TCM Syndrome( week 8) and undesirable pregnancy outcomes(42 days after giving birth) will be observed.
