microcirculation test Widefield capillary microscopy A technique used to evaluate finger nailfold capillaries, using a wide-angle stereomicroscope or ophthalmoscope; enlargement, ↑ tortuosity, or ↓ number of capillaries occur in connective tissue diseases–eg, Raynaud’s phenomenon, scleroderma–to evaluate extent of visceral involvement, MCTD, dermatomyositis, SLE.

Abstract. Nailfold capillaroscopy is a method of great diagnostic value in the differential diagnosis of primary versus secondary Raynaud´s phenomenon, of systemic sclerosis versus other so called connective tissue diseases and of additional diagnostic value in other entities. Rheumatologists, dermatologists, and angiologists in Germany have convened in an interdisciplinary working group in which they synergistically combined their expertise to develop a common nomenclature and standards for the technical performance of microcirculation test. The article gives an overview of historical and technical aspects of capillaroscopy, morphologic findings, and disease-specific patterns. It also provides a critical appraisal of its significance in the diagnosis and sequelae of these interdisciplinarily-managed diseases including its performance in children and gives an excursion in the potential perspectives of capillaroscopy in less common indications.

Step 1: connect one side of the power with the plug

Step 2: connect other side of the power with the sub-second line

Step 3 connect one end of the sub-second line with the extend line

Step 4: connect the two end of sub-second line with the machine and the monitor blood microcirculation test machine

Step 5 : connect the video line to the machine and the monitor

Step 6: connect the power. Now the machine is ready for testing

Circulatory system is also named cardiovascular system; this includes heart, arteries, veins, capillaries, blood cells and plasma. Thus, damage on any part of cardiovascular system would cause harmful consequences, such as dizziness, migraine, breathing difficulties, tiredness and body weakness. Severe consequences would be stroke, hypertension, heart attack, myocardial infarction and etc. Therefore, prevention is the only effective way to avoid these problems and the importance of prevention should be prioritized.

Heart is an organ which plays a critical role in blood circulation. Arteries and veins are responsible for transporting blood to the entire body and transporting back to the heart. Capillaries are permeable tiny blood vessels between small arteries and veins, which are sites for nutrients and gas exchange. Therefore, if there is blockage of blood vessels, nutrients and gas cannot be transported to the entire body and back to the heart. This will accelerate the occurrence of atherosclerosis and cardiovascular diseases.

The capillaroscopy is a non-invasive technique at nailfold level, making it possible to assess the characteristics of the nailfold distal capillaries, thanks to a lens and a light that shines on said spot.

The information it provides us with helps to complete the diagnosis of the vasculitic autoimmune process of the patient; it does not permit a diagnosis or specific therapeutic approach on its own.

For its correct visualisation, the patient is recommended:

Not to wear nail varnish and to avoid external harm (bumps, wounds, nail biting)
Not to smoke in the 2 hours prior to the test
To remain in the a room with a temperature of between 22ºC and 25ºC to avoid vasoconstriction episodes due to exogenous factors.

WHAT ARE ITS USES?

The capillaroscopy allows us to know the extent of the distal vascularisation, which is very important in systemic sclerosis and other connective pathologies, as well as to rule out systemic involvement in patients with Raynaud’s phenomenon with no other associated clinical involvement.

RAYNAUD IS PHENOMENON

The capillaroscopy of the nail bed is a simple, bloodless, economical method which is very useful for studying Raynaud’s phenomenon and other rheumatological conditions. Raynaud’s phenomenon can be defined as the change in the colouring of the fingers and/or toes in response to cold or stress. It traditionally progresses through three stages: paleness (vasospasm), cyanosis (due to increased carboxyhemoglobin) and erythema (reactive hiperemia).

Raynaud’s phenomenon can be primary (Raynaud’s disease) or secondary, associated with a connective tissue disease. Primary Raynaud’s phenomenon is responsible for around 60% of all new cases. 15-20% of cases of Raynaud’s phenomenon are due to a series of non- immunological processes, such as drugs, occupational diseases, neoplasms, etc. The remaining 15-20% are associated with connective tissue diseases.

Raynaud’s is present in over 90% of patients with scleroderma and in 70% of cases it is the first symptom. Although it seems impossible to predict that a patient with Raynaud’s will develop scleroderma, the presence of antinuclear antibodies (ANA) indicates a greater risk of onset.

SCLERODERMA

The nail bed capillaroscopy shows morphological alterations at an early stage in some connective tissue diseases of maximum rheumatological interest, particularly capillaroscopy. In these cases, the capillaroscopy traditionally shows the “sclerodermic pattern” characterised by: reduction or absence of capillaries in patches, capillary dilation, and sometimes mega-capillaries and splinter haemorrhages. This “sclerodermic pattern” appears early and when it is observed in patients with Raynaud’s phenomenon, even if it is not very obvious, it should lead to the search for sclerodermic manifestations in internal organs, which can be present without causing any symptoms. The combination of Raynaud’s phenomenon and a “sclerodermic pattern” in a capillaroscopy can precede and therefore predict the onset of scleroderma.

CAPILLAROSCOPY AND RHEUMATOLOGICAL CONDITIONS

In dermatomyositis, the capillaroscopy is similar and sometimes indistinguishable from that found in scleroderma. These patients generally present the other clinical, enzymatic or electromyographic manifestations of dermatomyositis that enable its recognition and diagnosis.
In mixed connective tissue disease (MCTD) or overlap syndromes that a sclerodermic component, the findings of the capillaroscopy can be similar although rarely are large capillary dilations and mega-capillaries observed. These capillaroscopies must be analysed by an expert.
In systemic lupus erythematosus, the alterations in the capillaroscopy are non-specific, and it is possible to find focal capillary reduction, albeit not very strong. The capillaries can be somewhat dilated and tortuous, sometimes with criss-crossing of the arterial and venous components (ringlets), the latter being the most characteristic finding in the capillaroscopy.
In primary Raynaud’s phenomenon, the most striking characteristic is the elongated capillaries with undulations throughout the arterial and venous components. Little or no reduction or dilation of the capillaries can be observed. Splinter haemorrhages are scarce and small.

Ultimately, this is an auxiliary diagnostic technique with great value in rheumatology and vascular disease.
