Objectives

A reliable tool to evaluate flow is paramount in systemic sclerosis (SSc). We describe herein on the one hand a systematic literature review on the reliability of laser speckle contrast analysis (LASCA) to measure the peripheral blood perfusion (PBP) in SSc and perform an additional pilot study, investigating the intra- and inter-rater reliability of LASCA.

Methods

A systematic search was performed in 3 electronic databases, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. In the pilot study, 30 SSc patients and 30 healthy subjects (HS) underwent LASCA assessment. Intra-rater reliability was assessed by having a first anchor rater performing the measurements at 2 time-points and inter-rater reliability by having the anchor rater and a team of second raters performing the measurements in 15 SSc and 30 HS. The measurements were repeated with a second anchor rater in the other 15 SSc patients, as external validation.

Results

Only 1 of the 14 records of interest identified through the systematic search was included in the final analysis. In the additional pilot study: intra-class correlation coefficient (ICC) for intra-rater reliability of the first anchor rater was 0.95 in SSc and 0.93 in HS, the ICC for inter-rater reliability was 0.97 in SSc and 0.93 in HS. Intra- and inter-rater reliability of the second anchor rater was 0.78 and 0.87.

Conclusions

The identified literature regarding the reliability of LASCA measurements reports good to excellent inter-rater agreement. This very pilot study could confirm the reliability of LASCA measurements with good to excellent inter-rater agreement and found additionally good to excellent intra-rater reliability. Furthermore, similar results were found in the external validation.  相似文献

Nailfold capillaroscopy is an easy, non-invasive technique to assess microvascular involvement in rheumatic diseases. Multiple studies describe capillaroscopic changes in systemic lupus erythematosus (SLE), including a wide range of non-specific findings. On behalf of the European League Against Rheumatism (EULAR) study group on microcirculation in rheumatic diseases, a systematic review was done to obtain all original research studies (in English) in which SLE patients had capillaroscopy. Forty such studies are identified. This article firstly provides a résumé of the results of these studies according to capillaroscopic parameters (density, dimensions, morphology, haemorrhages), semi-quantitative assessment and qualitative assessment of capillaroscopy in SLE patients. Secondly, the correlations between capillaroscopic parameters in SLE patients and clinical and laboratory parameters (including auto-immune parameters) are outlined. The following capillaroscopic parameters are found to be significantly more prevalent in SLE patients compared to healthy controls: tortuous capillaries, abnormal morphology and haemorrhages. Hairpin-shaped capillaries are significantly less prevalent than in healthy persons. The semi-quantitatively determined nailfold capillaroscopic score (NFC score) in SLE patients is also higher than in healthy controls. Several correlations between clinical and laboratory parameters and capillaroscopic parameters are identified in the review. Disease activity is correlated with NFC score in seven studies, with abnormal morphology (i.e. “meandering”) in one study and with haemorrhages in one study. Frequent attacks of Raynaud's phenomenon (RP) and gangrene are significantly correlated with dilated capillaries. In two studies a possible correlation between anti-SSA antibodies and lower density of capillaries is withheld. About other immune parameters conflicting results are found. In one study a significant negative correlation is found between 24-hour proteinuria and abnormal morphology (i.e. “meandering”). For the first time, an overview of the nailfold capillaroscopic changes that have been described in SLE and their correlations with clinical and laboratory findings is given. Further large-scale research on the identification of capillaroscopic changes in SLE and their correlations with standardised clinical and laboratory parameters, is ongoing at the EULAR study group on microcirculation in rheumatic diseases.  相似文献

Imaging techniques are increasingly important in clinical diagnostic work. Microcirculation is essential for function and survival of all tissues, but imaging techniques for microvascular monitoring of patients have only been used to a limited extent in clinical practice. The microcirculation is complex with its static and dynamic feature, and only skin and oral mucosa are readily accessible for microscopic examination. In addition, there is a no general agreement on which microvascular parameters and analysing techniques that could be useful. The aim of this article is to give an overview of techniques for human intra‐vital microscopy and to describe software and variables used to analyse pictures and film sequences of human microcirculation. We also present clinical examples where microvascular examinations have been shown to be of diagnostic value. Improved techniques for assessing microvascular morphology and physiology will probably become important tools in clinical work in many disciplines in the near future.  相似文献

目的探讨2型糖尿病(T2DM)周围神经病变(DPN)患者甲襞微循环的变化特点。方法住院T2DM患者600例,根据肌电图结果分为DPN组488例和无DPN(NDPN)组112例,另选择30例正常人作为健康对照组,检查3组的甲襞微循环形态、流态、血管周围状态等指标,并进行比较。结果 (1)微循环特征:与健康对照组比较,DPN组和NDPN组甲襞微循环形态和袢周积分明显升高(P<0.01);与NDPN组比较,DPN组袢周积分和总积分升高(P<0.01)。(2)甲襞微循环表现:与健康对照组比较,2组患者袢周渗出、出血积分升高,DPN组管袢数、乳头积分升高,袢顶直径减小(P<0.05,P<0.01),且DPN组袢顶直径和乳头积分与NDPN组比较差异亦有统计学意义(P<0.05)。(3)病变程度:2组患者甲襞微循环正常者比例明显低于健康对照组(P<0.01),DPN组中度异常的比例高于NDPN组(52.9%vs 19.6%,P<0.01),正常者和轻度异常者比例低于NDPN组(分别为13.5%vs 31.2%,25.0%vs 43.8%,P<0.01)。结论 T2DM患者均存在甲襞微循环异常,DPN患者甲襞微循环异常更为严重,可能是DPN的病因之一。  相似文献
