tasly microcirculation in 430 patients with Rheumatoid Arthritis
tasly microcirculation in 430 patients with Rheumatoid Arthritis
Background: Microvascular changes are one of the first obvious steps in numerous inflammatory diseases such as rheumatoid arthritis (RA). Nailfold video capillaroscopy (NFC) is an easy, reliable and safe method for evaluating peripheral microangiopathy. The objective of this study was to examine nailfold microcirculation in RA patients, assess morphological and structural changes quantitatively and qualitatively, and recognize useful changes.
Methods: A total of 430 patients diagnosed with RA were examined in a period of 4 years. NFC was performed on all fingers of both hands in each patient. Different parameters indicating microvascular changes were detected and analyzed; such as microvascular architecture, capillary distribution disturbances, capillary morphology, capillary density, efferent/afferent limb ratio, subpapillary venular plexus and morphological abnormalities. The obtained results were categorized into normal pattern, nonspecific morphological abnormality and scleroderma pattern.
Results: The mean age of participants was 51.03±14.54 (19-87 years) that consisted of 359 females and 71 males. Based on the findings, angiogenesis (74.7%) was the most pathological condition observed after tortuosity (99.5%). 7.2% and 20.9% of patients were categorized into normal and scleroderma pattern group, respectively. Among morphological abnormalities, angiogenesis, isolated enlarged loop, irregular enlarged loop and architectural derangement were significantly more frequent in scleroderma than normal pattern (p<0.001).
Conclusion: NFC may play an important role in monitoring RA disease and patients’ follow-up. Therefore, in our opinion it could be considered in the course and follow-up of rheumatoid arthritis.
What is tasly microcirculation Testing conditions?
What is tasly microcirculation Testing conditions?
1) Check the room temperature and humidity. Room temperature and humidity should be kept relatively constant. room temperature should be maintained in the 22-24 degree , relative humidity about 70%
2) The patient generally take seats, keep the height of the hand the same with heart
3) Preparation of paraffin oil or cedar oil.Drop 2 drops in the nailfold skin. (Purpose prove light transmission, and reduce skin scattering)
4) Testing generally be in the morning or afternoon, and review should at the same time every day .
5) The patient should
a. Avoiding intense activity or manual labor within one hour before testing
b. Take a rest about 15-30 minutes before testing
c. Can not take any drug which will affect the cardiovascular vessels before testing
d. Does not smoke , wash hands or eat within an hour before testing
e. Pay attention to the influence of the Female menstrual
tasly microcirculation: A Basic Screening Tool in Raynaud’s Phenomenon
tasly microcirculation: A Basic Screening Tool in Raynaud’s Phenomenon
The term “Raynaud’s phenomenon” refers to a defined triphasic colour change pattern (white, blue, red) of the skin of the fingers. The initial pallor, which may lead to cyanosis (blue coloration) of the digits, is followed by reactive hyperemia and can be accompanied by numbness, paresthesias and pain. Raynaud’s is triggered by exposure to cold, emotional stress and specific drugs. Pathophysiologically it is characterized by an excessive vasoconstrictive response (dominance of vasoconstrisctive over vasodilatory factors) of the small arterioles and the digital arteries.Etiologically it can be classified as primary or secondary, mainly either to systemic sclerosis and related diseases, or to the thoracic outlet syndrome. As such, Raynaud’s phenomenon represents an important clinical manifestation of microvascular involvement. Rare cases of paraneoplastic Raynaud’s have been described, the pathogenesis of which remains unclarified, has however been most likely attributed to neuroendocrine substances secreted by the tumor.Despite the evolution of the technology involved over the decades, nailfold capillaroscopy remains very simple in principle. The term refers to the non-invasive observation of the nailfold capillary bed. Nailfold capillaroscopy can be performed with basic equipment such as a magnifying lens, an ophthalmoscope, a dermatoscope/ stereomicroscope or a conventional wide field microscope; the nailfold video capillaroscope, however, is the gold standard tool, and provides the technology for the visualization and analysis both of morphological as well as rheological parameters of the skin microvasculature. Qualitative and quantitative microangiopathic parameters that can be recorded and analyzed include, among others, microhemorrhages, plexus morphology, capillary density, and morphologic anomalies of the end row loops. In normal conditions, or in primary Raynaud’s, the normal nailfold capillaroscopic pattern shows a regular disposition of the capillary loops along with the nailbed. In subjects suffering from secondary Raynaud’s phenomenon, alterations of the capillaroscopic findings should alert the physician of the possibility of a connective tissue disease or other conditions not yet detected.This review aims to outline the major characteristics of the normal nailfold microvascular network and the healthy variations that may be encountered in relation to age, race, employment etc, and highlight its applicability not only as a powerful tool in the screening of a variety of vascular disorders, in particular of autoimmune origin, but also as a potent tool in the follow-up of patients with established microvascular disorders in response to treatment.As microcirculation involvement is attracting increasing interest in chronic vascular diseases such as diabetes mellitus or hypertension, as a prognostic marker for macrovascular disease and target organ involvement, the acquaintance with and application of techniques assessing microvascular compromise gains particular significance. The advantages of capillaroscopy (low cost, uninvasiveness, repeatability, high sensitivity, good specificity and easy interpretation of the results) render this technique a valuable asset for the clinician.
