摘要

比较系统性红斑狼疮(SLE)、原发性Sjögren病(pSjD)、抗磷脂综合征(APS)、健康对照(HC)和无这些系统性风湿病(SRD)的不良妊娠结局(APO)妇女的胎盘中免疫细胞亚群和干扰素(IFN)的表达。从格罗宁根大学医学中心的病理生物库中恢复了HC, SLE, pSjD, APS以及2008年至2022年间患有胎儿生长受限(FGR),自发性早产(PTB)或FGR和先兆子痫(FGR/PE)的患者的胎盘活检。临床特征和APO从医疗记录中检索。免疫组化检测黏液病毒抗性蛋白1 (MxA)、CD3、CD20、CD56、CD68、CD123和Foxp3。使用自动检测分类器确定阳性细胞的比例,同时对MxA表达进行半定量评估,区分母体(蜕膜)和胎儿(绒毛)组织。最后,对胎盘病变进行分类。我们的研究纳入了11例SLE、4例pSjD、8例APS、4例PTB、8例FGR、8例FGR/PE和11例HC患者的胎盘。在SRD患者中发现了高APO率(70%)。SRD患者蜕膜和绒毛中巨噬细胞(CD68+)计数高于HC,但T (CD3+)、B (CD20+)、NK (CD56+)和T调节细胞(Foxp3+)计数无差异。未发现浆细胞样树突状细胞(CD123+)。此外,这些SRD患者绒毛的MxA值高于HC,而蜕膜的MxA值则高于HC。与HC相比,SLE、pSjD和APS患者胎盘中巨噬细胞计数增加,干扰素上调。因此,促炎环境可能是诱发胎盘功能障碍的关键,这可能导致APO的后续发展。

Immunohistochemical analysis reveals higher Myxovirus resistance protein 1 expression and increased macrophage count in placentas from patients with systemic rheumatic diseases.

To compare immune cell subsets and interferon (IFN) expression in placentas from patients with systemic lupus erythematosus (SLE), primary Sjögren's disease (pSjD), antiphospholipid syndrome (APS), healthy controls (HC) and of women with adverse pregnancy outcomes (APO) without these systemic rheumatic diseases (SRD). Placenta biopsies from HC, SLE, pSjD, APS, and patients with fetal growth restriction (FGR), spontaneous preterm birth (PTB), or FGR and preeclampsia (FGR/PE) attended between 2008 and 2022 were recovered from the pathology biobank of the University Medical Center Groningen. Clinical characteristics and APO were retrieved from medical records. Immunohistochemistry was performed for Myxovirus resistance protein 1 (MxA), CD3, CD20, CD56, CD68, CD123, and Foxp3. The proportion of positive cells was established using an automated detection classifier, while MxA expression was assessed semi/quantitatively discriminating between maternal (decidua) and fetal (villi) tissue. Finally, placental lesion classification was performed. Our study included placentas from 11 SLE, 4 pSjD, 8 APS, 4 PTB, 8 FGR, 8 FGR/PE patients and 11 HC. A high rate of APO (70%) was identified in SRD patients. Patients with SRD had a higher macrophage (CD68+) count in decidua and villi than HC, but no differences were observed in T (CD3+), B (CD20+), NK (CD56+) and T regulatory (Foxp3+) cell count. No plasmacytoid dendritic cells (CD123+) were identified. Furthermore, patients with these SRD had higher MxA values than HC in villi but not in decidua. SLE, pSjD and APS patients have an increased macrophage count and interferon upregulation in the placenta compared to HC. Therefore, a pro-inflammatory environment might be key inducing placental dysfunction, which may lead to subsequent APO development.

期刊介绍: RHEUMATOLOGY INTERNATIONAL is an independent journal reflecting world-wide progress in the research, diagnosis and treatment of the various rheumatic diseases. It is designed to serve researchers and clinicians in the field of rheumatology. RHEUMATOLOGY INTERNATIONAL will cover all modern trends in clinical research as well as in the management of rheumatic diseases. Special emphasis will be given to public health issues related to rheumatic diseases, applying rheumatology research to clinical practice, epidemiology of rheumatic diseases, diagnostic tests for rheumatic diseases, patient reported outcomes (PROs) in rheumatology and evidence on education of rheumatology. Contributions to these topics will appear in the form of original publications, short communications, editorials, and reviews. "Letters to the editor" will be welcome as an enhancement to discussion. Basic science research, including in vitro or animal studies, is discouraged to submit, as we will only review studies on humans with an epidemological or clinical perspective. Case reports without a proper review of the literatura (Case-based Reviews) will not be published. Every effort will be made to ensure speed of publication while maintaining a high standard of contents and production. Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
