“…Although IRT measurements correlate only moderately with density of capillaries, abnormal initial thermography associates with nailfold capillaroscopy patterns and identifies SSc that are more likely to develop digital ulcers and require more frequent surgical debridement [33,34]. Of interest, baseline thermographic temperature is influenced by gender but, not race and trends show decreased perfusion in tobacco users relative to nonsmokers, which highlights the importance of subject characterization [35]. Additionally, while not specifically studied in SSc, lower facial skin and submental triangle region temperatures, measured by IRT, can help identify patients with obstructive sleep apnea [36].…”

Purpose of reviewVascular assessment in systemic sclerosis (SSc) is included in classification criteria for this disease, thus routinely used in the evaluation of patients in which this diagnosis is being considered. In this review, imaging techniques for assessment of vascular involvement in SSc hands and skin are discussed. Recent findingsLongitudinal use of imaging techniques has important implications for understanding the progressive vasculopathy and fibrotic transition in SSc. Nailfold and oral capillaroscopy as well as laser speckle contrast analysis are established techniques for vascular functional assessment, but longitudinal use is challenged by equipment costs and clinical time constraints. Ultrasound techniques are well described but require technical training. Advances in mobile infrared thermography and optical coherence tomography could potentially provide a point-of-care, quantitative outcome measure in clinical trials and practice.

“…This technique takes advantage of digital cameras to record and quantify the process of skin thermoregulation, effectively assessing digital perfusion, although it requires careful monitoring of acclimation time, camera-individual distance, ambient temperature, and humidity, as well as proper characterization of subjects (especially gender, smoking habit) [79,[85][86][87][88]. Moreover, it can be combined with a local cold challenge: exposure to a localized cold stimulus largely mimics an RP attack, thus allowing dynamic vascular assessment [89].…”

Correlation between Microvascular Damage and Internal Organ Involvement in Scleroderma: Focus on Lung Damage and Endothelial Dysfunction

et al. 2022

Background. Systemic sclerosis (SSc) is an incurable connective tissue disease characterized by decreased peripheral blood perfusion due to microvascular damage and skin thickening/hardening. The microcirculation deficit is typically secondary to structural vessel damage, which can be assessed morphologically and functionally in a variety of ways, exploiting different technologies. Objective. This paper focuses on reviewing new studies regarding the correlation between microvascular damage, endothelial dysfunction, and internal organ involvement, particularly pulmonary changes in SSc. Methods. We critically reviewed the most recent literature on the correlation between blood perfusion and organ involvement. Results. Many papers have demonstrated the link between structural microcirculatory damage and pulmonary involvement; however, studies that have investigated correlations between microvascular functional impairment and internal organ damage are scarce. Overall, the literature supports the correlation between organ involvement and functional microcirculatory impairment in SSc patients. Conclusions. Morphological and functional techniques appear to be emerging biomarkers in SSc, but obviously need further investigation.
