目的 分析沙参麦冬汤联合硫酸羟氯喹对阴虚津亏型原发性干燥综合征（pSS）患者的治疗效果。方法 本研究采用回顾性病例对照研究，选取2023-11—2025-06期间我院确诊的114例pSS阴虚津亏型患者，依据治疗方案不同分成研究组（57例）、对照组（57例）。对照组接受硫酸羟氯喹治疗，研究组接受沙参麦冬汤、硫酸羟氯喹联合治疗，两组持续治疗2个月。观察并对比两组疗效、中医证候积分、外分泌腺功能（泪流量、唾液流率）、临床症状[欧洲抗风湿病联盟干燥综合征患者疾病活动指数（ESSDAI）、欧洲抗风湿病联盟干燥综合征患者报告指数（ESSPRI）]、免疫球蛋白[免疫球蛋白G（IgG）、IgA、IgM]水平。结果 与对照组70.18%相比，研究组治疗有效率91.23%明显较高（P＜0.05）；治疗2个月，与对照组相比，研究组中医证候积分较低，泪流量、唾液流率较高（P＜0.05）；治疗2个月后与对照组相比，研究组ESSDAI分值、ESSPRI分值明显较低（P＜0.05）；治疗2个月后与对照组相比，研究组血清IgG、IgA以及IgM水平明显较低（P＜0.05）；两组安全性对比，无明显差异（P＞0.05）。结论 沙参麦冬汤、硫酸羟氯喹联合治疗阴虚津亏型pSS效果确切，可减轻临床症状，改善免疫功能、外分泌功能，且无明显不良反应。

目的 对比羟氯喹联合半量激素与足量糖皮质激素（激素）治疗IgA肾病在减少尿蛋白、保护肾功能方面的效果以及不良反应的发生率。方法 筛选2020年6月—2022年1月我院收治基线尿蛋白排泄量>1 g/ d、基线估算肾小球滤过率>15 mL/min的IgA肾病患者为研究对象,随机分为羟氯喹+半量激素（Q+G）组及足量激素（G）组。Q+G组予羟氯喹及泼尼松0.5 mg/（kg·d）,G组予泼尼松 1 mg/（kg·d）,比较2组在治疗2、4、6个月后24 h尿蛋白定量的改变值;比较2组6个月内24 h尿蛋白较基线下降>30%的比例、24 h尿蛋白定量下降至1 g以下的比例、估算肾小球滤过率下降>30%的比例以及不良反应发生率。结果 纳入Q+G组49例,G组46例。2组在治疗2、4、6个月后的24 h尿蛋白定量改变值、6个月内24 h尿蛋白较基线下降>30%的比例、24 h尿蛋白定量下降至1 g以下的比例、6个月内估算肾小球滤过率下降>30%的比例比较差异均无统计学意义（均P>0.05）;Q+G组不良反应发生率低于G组（P<0.05）。结论 与足量激素治疗相比,羟氯喹联合半量激素治疗尿蛋白持续>1 g/d的IgA肾病患者在减少尿蛋白、保护肾功能中的效果相近,而不良反应的发生率较低。

Objective Compared with full-dose glucocorticoid,to evaluate the effect of hydroxychloroquine combined with half-dose glucocorticoid in the treatment of IgA nephropathy in reducing urinary protein and protecting renal function,as well as the incidence of adverse reactions. Methods From June 2020 to January 2022,patients with IgA nephropathy whose baseline urinary protein excretion>1 g/d and baseline estimate glomerular filtration rate>15 mL/min were enrolled and randomly divided into hydroxychloroquine combined with half-dose glucocorticoid(Q+G)group and full-dose glucocorticoid(G)group. Each patient in Q+G group was given oral hydroxychloroquine and oral prednisone at a dose of 0. 5 mg/(kg·d). Each patient in G group was given prednisone at a dose of 1 mg/(kg·d). The changes in 24-hour urine protein quantification between the two groups at 2,4 and 6 months of treatment were compared;the proportions of 24-hour urine protein decreased by more than 30%,24-hour urine protein decreased to less than 1 g,estimate glomerular filtration rate decreased >30% and adverse reactions within 6 months were compared between the two groups. Results Fourty-nine cases were enrolled in Q+G group and 46 cases in G group. There was no significant difference in the 24-hour urine protein changes between the two groups at 2,4 and 6 months of treatment. The proportion of 24-hour urine protein decreased by 30%,the proportion of the 24-hour urine protein decreased to below 1 g and the proportions of patients whose estimate glomerular filtration rate decreased by >30% within 6 months between the two groups were not significantly different. The proportion of adverse reactions in Q+G group was lower than that in G group. Conclusions Hydroxychloroquine combined with half-dose glucocorticoid has similar effects in reducing urinary protein and protecting renal function and lowering incidence of adverse reactions compared with full-dose glucocorticoid therapy in the treatment of patients with IgA nephropathy whose urinary protein excretion > 1 g/d.
