Background: The Diego antigen commonly occurs in certain Asian and South American Indian populations. In general, hemolysis caused by anti-Diego antigen is not severe, and exchange transfusion is rarely needed. Here, we report a neonate with moderate hemolytic disease caused by anti-Diego antigen in the Baoji area of China.
Case Presentation: A 39-week gestation male newborn of Han nationality was delivered by second cesarean section because of scarred uterus. The newborn's birth weight was 3700 g with an Apgar score of 9. Four hours after delivery, transcutaneous bilirubin test revealed a level of 17 mg/dl. After 23 hours, the neonate developed anemia and hyperbilirubinemia. Bacterium, virus and other pathogens, as well as tests for arcuate and glucose-6-phosphate dehydrogenase, were all negative. Direct antiglobulin test of the neonate was positive. Diego antigens of the baby and his father were positive, while his mother was negative. The newborn was successfully cured with phototherapy and one-dose intravenous injection of human albumin.
Conclusions: It is important to consider and test for the anti-Diego antibody in cases of hemolytic disease of the newborn of the Han ethnicities of China.

This case report presents a complex medical scenario involving early 60s female patient with a history of chronic lymphocytic leukaemia (CLL) complicated by Evans syndrome, characterised by autoimmune haemolytic anaemia and immune thrombocytopenia. The patient had received various treatments, including steroids, rituximab, cyclosporine and acalabrutinib. The patient's neurological symptoms began around 3 years prior to presentation, with shaking of her right leg, followed by shaking of both hands, particularly the left hand.

Background: Autoimmune hemolytic anemia (AIHA) following allogeneic hematopoietic stem cell transplantation (allo-HSCT) is often refractory and relapsing, leading to increased mortality post-HSCT.
Methods: We retrospectively analyzed the cases of patients with transfusion-dependent β-thalassemia (TDT) who underwent allo-HSCT to study their clinical features, the occurrence of AIHA post-HSCT, and treatment response and to explore the possible pathogenesis of AIHA.
Result: A total of 113 patients were registered in the study, out of whom 14 developed AIHA following allo-HSCT, resulting in a cumulative incidence of 12.

Prenatal exome sequencing (ES) can establish rare genetic diagnoses in a fetus but may also lead to occult genetic diagnosis in a biological parent. We present a case of dual fetal and maternal diagnosis by prenatal ES, in a fetus with unexplained anemia and in a pregnant patient with sickle cell disease (SCD) and recurrent unexplained hypoxia. ES identified a novel, likely pathogenic gamma globin variant, HbF Mission Bay HBG2 (c.

Fibrinolytic enzymes are promising in treating cardiovascular diseases due to their capacity to dissolve blood clots. The fibrinolytic enzyme from Arthrospira platensis (FEAP) was purified by ion exchange chromatography to investigate its ability to activate plasminogen, as well as its thrombolytic and fibrinogenolytic potential. Subsequently, two different cytotoxic assays (MTT and NR) and hemolysis test were performed to evaluate FEAP's safety.
