Objective: The presence of red blood cell (RBC) irregular antibodies can severely jeopardize mother and child and bring trouble to the treatment of anemia. The aim of this study was to analyze the specificity of RBC irregular antibody in inpatients.
Methods: An analysis was performed on samples from patients with RBC irregular antibodies. Antibody screening positive samples were analyzed.
Results: Among the 778 cases of irregular antibody positive samples, 214 were from males and 564 from females. History of blood transfusion accounted for 13.1% of the total. Of the women, 96.8% had a pregnancy. A total of 131 antibodies were identified. The antibodies included 68 Rh systematic antibodies, 6 MNS systematic antibodies, 6 Lewis systematic antibodies, 2 Kidd systematic antibodies, 10 autoantibodies, and 39 antibodies of uncertain specificity.
Conclusion: Patients with blood transfusion or pregnancy history are prone to produce RBC irregular antibodies.

Purpose: To explore how serum diabetes autoantibodies are related to the development of early diabetic retinopathy in children with type 1 diabetes mellitus.
Methods: In this prospective and observational study, 62 patients with type 1 diabetes mellitus who had not yet developed clinical diabetic retinopathy were followed up for at least 5 years. Healthy volunteers aged 10 to 20 years were also included.

Purpose: To compare ovarian function measures in euthyroid women with normogonadotropic anovulation in subclinical hypothyroidism (SCH) or thyroid autoimmunity (TAI) to those without thyroid dysfunction.
Design: A prospective open-label cohort study analyzed anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone, estradiol and testosterone concentrations, ovarian volume, and polycystic ovarian morphology (PCOM) incidence between women with and without SCH or TAI in two study arms: polycystic ovary syndrome (PCOS) and hypothalamic-pituitary-ovarian dysfunction (HPOD).
Results: The prevalence of circulating thyroid peroxidase antibodies (TPOAb) was higher in the PCOS compared to the HPOD arm (p = 0.

Objective: To analyze the type and distribution characteristics of irregular antibodies in 71 847 hospitalized patients who prepared to accept blood transfusion, and to explore their role in safe blood transfusion.
Methods: 71 847 patients who applied for red blood transfusion from January 2020 to October 2023 were selected. All specimens were screened and identified for the irregular antibody by microcolumn gel antiglobulin technique.

Objective: To investigate the cause of the production of anti-D and anti-E mixed antibody in an RhD positive patient.
Methods: The ABO/Rh blood group typing and irregular antibody specificity were identified by conventional serological methods, the gene exon 1-10 and heterozygous analysis were performed by sequence-specific primer polymerase chain reaction (PCR-SSP), and the whole exon sequence was analyzed by first-generation sequencing.
Results: The patient's Rh blood group was weak D Type33, with the allele was , the patients was found to be heterozygous, with an Rh typing of Ccee, and the patient had developed anti-D combined with anti-E mixed antibodies.

Chronic musculoskeletal pain in pediatric patients can be challenging to diagnose, particularly in the absence of overt signs of autoimmune disease, as these episodes can manifest episodically. We present a case of a 14-year-old female patient with a two-year history of episodic "bone pain," morning stiffness, and infrequent fever and fatigue. Laboratory testing revealed an antinuclear antibody (ANA) titer of 1:1280 with a nuclear homogeneous pattern and a mildly elevated erythrocyte sedimentation rate (ESR).
