Abstract
Objective: To investigate the clinical features of coronavirus disease 2019 (COVID-19) in patients with aplastic anemia (AA) undergoing immunosuppressive therapy (IST) . Methods: In this prospective cohort study, we collected the demographic and clinical data of patients with AA and COVID-19 from December 1, 2022, to January 31, 2023. We described the clinical features of COVID-19 among patients with AA and evaluated the effects of IST on the signs and severity of COVID-19. Results: A total of 170 patients with AA and COVID-19 were included. The common early symptoms, including fever, dizziness or headache, muscle or body aches, and sore throat, disappeared within 1-2 weeks. Approximately 25% of the patients had persistent fatigue within 2 weeks. Many patients experienced cough after an initial 1-3 days of infection, which lasted for more than 2 weeks. There were no differences in the duration of total fever episodes and maximum body temperature when patients were stratified according to whether or not they underwent IST, by IST duration, or by use of anti-lymphocyte globulin (ALG) (P>0.05). No differences were observed in the occurrence of symptoms in either the early or recovery stages when patients with AA were stratified according to whether or not they underwent IST, or by IST duration (P>0.05). However, patients who received ALG had fewer fever episodes within 1 week after infection (P=0.035) and more sore throat episodes within 2 weeks after infection (P=0.015). There were no other significant differences in clinical symptoms between patients who did and patients who did not receive ALG (P>0.05) . Conclusion: The majority of patients with AA and COVID-19 recovered within 2 weeks of noticing symptoms when treated with IST.

Abstract
目的 探索真实世界门诊治疗再生障碍性贫血(AA)患者的诊断流程、治疗及疗效。 方法 评估2018年1月至2019年12月门诊治疗176例AA患者的诊断流程、治疗方案及疗效。 结果 患者出现症状至首次就诊中位时间7(5~120)个月,就诊原因包括出血(52.3%)、贫血(51.7%)、感染(6.8%)。诊断流程中168例(95.5%)患者完成髂骨骨髓穿刺(骨穿),仅22例(17.1%)完善了多部位骨穿(胸骨分类);骨髓活检完成率85.1%(143/168);只有59.5%(100/168)和58.9%(99/168)完成了骨髓流式免疫分型及染色体核型分析;86例(48.5%)完成阵发性睡眠性血红蛋白尿(PNH)克隆筛查;造血祖细胞培养检查完成率最低,仅45例(26.8%)。环孢素A(CsA)联合雄激素及左旋咪唑为最常见治疗方案,总计77例(43.8%),其次为CsA联合雄激素45例(25.6%),单用CsA者24例(13.6%),单用雄激素者16例(9.1%),14例(7.9%)患者确诊后选择中药或未治疗。根据门诊复诊频率将176例患者分为复诊规律组(每年≥4次)130例(73.9%)和复诊欠规律组(每年<4次)46例(26.1%)。复诊规律组6个月有效率较高(52.5%对28.0%,P=0.005),12个月高质量缓解率更好(40.7%对16.7%,P=0.027),24个月复发率更低(4.4%对36.4%,P=0.001)。 结论 真实世界治疗的AA患者诊断流程需重视多部位骨穿检查并完成PNH克隆筛查、流式免疫分型、染色体核型分析及造血祖细胞培养检查;门诊规律复诊患者可获得高质量缓解,复发率低,推荐每年至少复诊4次。

Abstract
This study investigated the effects of dietary Arginine (Arg) on performance, intestinal antioxidative capacity, immunity, and gut microbiota in Chinese yellow-feathered chickens. One thousand two hundred 1-day-old female Qingyuan partridge chickens were randomly assigned to 5 groups with 6 replicates of 40 birds each. Chickens were fed diets with 5 levels of total Arg (8.5, 9.7, 10.9, 12.1, and 13.3 g/kg) without antibiotics for 30 d. The ADFI, ADG, and feed conversion ratio were improved with dietary Arg levels (P < 0.05). The proportions of CD3+ and CD4+/CD8+ lymphocytes responded in a linear (P < 0.05) manner and those of CD4+ in a linear or quadratic (P < 0.05) manner as dietary Arg levels increased. Dietary Arg level had a linear (P < 0.05) or quadratic (P < 0.05) effect on the gene expression of glutathione peroxidase 1, heme oxygenase 1, nuclear factor erythroid 2-related factor 2, and the activities of glutathione peroxidase and total antioxidative capacity in the jejunum and ileum. The relative expression of IL-1β, myeloid differentiation primary response 88, and Toll-like receptor 4 decreased linearly (P < 0.05) in the ileum with increasing dietary Arg levels; secretory IgA contents were increased. In addition, sequencing data of 16S rRNA indicated that dietary Arg increased the relative abundance of Firmicutes phylum, Romboutsia and Candidatus Arthromitus genera, while decreased that of Clostridium sensu stricto 1. A diet containing 12.1 g Arg/kg promoted growth performance, intestinal antioxidation, and innate immunity and modulated gut microbiota in yellow-feathered chickens.
