## TL;DR

This study shows that IVIg treatment helps raise antibody levels and reduce infection risk in NHL patients after CD20 monoclonal antibody therapy.

## Contribution

The study provides clinical evidence for IVIg's effectiveness in managing low antibody levels post-CD20 therapy in B-cell NHL patients.

## Key findings

- IVIg significantly increased total Ig levels in patients within 1–3 days of treatment.
- IVIg-treated patients had a higher proportion reaching 20 g/L Ig levels compared to the control group.
- IVIg showed a trend toward reducing new infections and had mostly mild side effects.

## Abstract

观察静注人免疫球蛋白（pH4）（简称IVIg）联合治疗对B细胞非霍奇金淋巴瘤（NHL）患者总免疫球蛋白（Ig）水平的影响，评估IVIg改善B细胞NHL经CD20单抗治疗后低丙种球蛋白血症的临床有效性。

回顾性分析2018年1月至2022年6月期间于苏州大学附属第一医院血液科住院就诊的98例B细胞NHL并使用CD20单抗治疗后低丙种球蛋白血症患者的临床资料。其中，IVIg组70例、常规治疗组28例。为排除输注血浆对总Ig水平的干扰，对未使用血浆IVIg组（53例）和常规治疗组（25例）的总Ig水平进行统计分析。通过观察IVIg对于患者总Ig水平提升效果和持续时间，分析IVIg治疗效果，以及通过比较其他血液生化指标，分析IVIg的控制感染效果。并观察IVIg在临床中应用的安全性。

IVIg组IVIg治疗后1～3 d内总Ig水平高于IVIg治疗前［（20.67±4.17）g/L对（17.16±1.76）g/L，P<0.001］。22例患者IVIg治疗后1～7 d、8～14 d、15～30 d的总Ig水平较治疗前差异均具有统计学意义（均P<0.001）。常规治疗组住院后1～3 d内总Ig水平均值较入院时差异无统计学意义［（18.12±1.84）g/L对（18.43±1.79）g/L，P>0.05］。IVIg组在IVIg治疗后1～3 d内总Ig水平达到20 g/L的患者比例显著高于入院1～3 d内的常规治疗组（57.69％对0，P<0.001）。12例入组时中性粒细胞水平低于正常值的IVIg组患者治疗后1～3 d、4～7 d、8～14 d的中性粒细胞水平均较治疗前升高（均P<0.05）。IVIg组治疗后新发感染患者比例低于常规治疗组［22.64％（12/53）对36.00％（9/25），P>0.05］。IVIg组（70例）中8例患者出现1～2级的不良反应，其中5例出现恶心呕吐、2例出现皮疹、1例肌肉关节痛，未观察到3级以上的不良反应。

IVIg提高B细胞NHL患者CD20单抗治疗后Ig和中性粒细胞水平，对控制新发感染可能有一定作用。IVIg治疗B细胞NHL使用CD20单抗后低丙种球蛋白血症疗效确切且安全性良好。
