ABSTRACT

Systemic sclerosis may be complicated by digital ulcers. Nailfold capillaroscopy on one finger might reflect an increased risk of digital ulcer (DU). In the present study we studied the correlations between a history of ulcer and capillary findings on the finger. METHOD: This study is part of Sclerocap, a multicenter study aiming at validating prospectively the prognostic value of Maricq's and Cutolo's capillaroscopic classifications during a three-year longitudinal follow-up. A history of past or present digital ulcer was recorded at inclusion and nailfold capillaroscopy was performed. Elementary findings as well as Cutolo and Maricq's classifications were assessed. RESULTS: 387 patients were included in Sclerocap (327 females, 60 males) and 3096 fingers were examined by capillaroscopy at inclusion: 316 fingers (10%) belonging to 113 patients had a history of DU. Late Cutolo's stage was statistically correlated with a history of DU, both by univariate: OR 2.08 [1.09-3.96] and multivariate analysis: OR 1.97 [1.06-3.63]. Among the elemental abnormalities, only edema and decreased capillary density were correlated with a history of DU by multivariate analysis: respectively OR 1.92 [1.17-3.16] and 0.65 [0.49-0.85]. CONCLUSION: This cross-sectional study in a large cohort of patients with systemic sclerosis shows a correlation between a history of digital ulcer and edema, a decrease in capillary density and the late stage in Cutolo's classification. The extent of capillary abnormalities on one finger is associated with a history of local digital ulcer. Capillaroscopy might be used to predict the risk of DU but these results need first to be confirmed by prospective studies.

ABSTRACT

OBJECTIVE: To evaluate the prevalence and clinical correlates of peripheral arterial disease of the upper limbs in patients with systemic sclerosis (SSc), as detected with finger brachial pressure index (FBPI) measurements. METHODS: This work is based on the baseline data of the SCLEROCAP multicenter cohort of SSc patients. Finger systolic blood pressure was measured with laser Doppler flowmetry, and the FBPI was obtained as its ratio over the ipsilateral brachial systolic blood pressure. An FBPI of <0.70 was used as the diagnostic criterion for occlusive arterial disease of the upper limbs. Thus, the prevalence of defined arterial disease as well as its clinical, biologic, and capillaroscopic correlates were evaluated. RESULTS: Among 326 enrolled patients, 177 (54.3%) met the criterion for arterial disease (FBPI <0.70). No association was found with the type of SSc nor with the type of associated antinuclear antibodies, but a significant association was found with the duration of the disease (P < 0.001), the capillaroscopic pattern (P < 0.001), and most strikingly with the presence of digital ulcers (42.9% versus 13.4%; P < 0.001). A quantitative relationship was found between the FBPI and the prevalence of digital ulcers and was shown to be independent from the capillaroscopic pattern. CONCLUSION: This cross-sectional study shows a high prevalence of arterial disease of the upper limbs in patients with SSc. FBPI appears to be a strong and independent predictor of digital ulcers. This study suggests that both macro- and microangiopathy are contributing to the ischemic damage of the fingertips.

ABSTRACT

Over the past decade, improvements in medical treatment and revascularization techniques have been beneficial for patients with peripheral artery disease in the late stage of critical limb ischemia (CLI). We evaluated the putative reduction in the number of major amputees in the Cohorte des Patients ARTeriopathes (COPART) cohort over time. Patients were selected from this multicenter cohort, from 2006 to 2016, for CLI according to Trans-Atlantic Inter-Society Consensus for the Management of Peripheral Arterial Disease II criteria. Patients included before and after 2011 were compared. Patients were followed for 1 year. Primary outcome was the rate of major amputations. Secondary outcomes were minor amputations, deaths from all causes, cardiovascular deaths; 989 patients were included, 489 before 2011 and 450 after 2011. There was a significant decrease in rates of major amputation after 2011 (17% vs 25%), confirmed in multivariate analysis (odds ratio [OR]: 1.5 [1.1-2.2]), an increase in revascularization, particularly distal angioplasty (OR: 2.7 [1.7-4.4]) and increased statin intake (OR: 1.6 [1.1-2.1]). For secondary outcomes, there was no significant difference. Limb prognosis of CLI patients has improved over the past decade, possibly due to more revascularizations, particularly distal ones, and increased statin use.

ABSTRACT

OBJECTIVES: We assessed the correlation between severity of systemic sclerosis (SSc) and current staging systems based on nailfold capillaroscopy. METHODS: SCLEROCAP is a multicenter prospective study including consecutive scleroderma patients who have a yearly routine follow-up with capillaroscopy and digital blood pressure measurement. Capillaroscopy images were read by two observers blinded from each other, then by a third one in the case of discordance. A follow-up of 3 years is planned. The present study assessed the correlation between severity of systemic sclerosis (SSc) and current staging systems based on nail fold capillaroscopy at enrollment in the SCLEROCAP study. Univariate and multivariate logistic regression analysis was performed for both the Maricq and Cutolo classifications. RESULTS: SCLEROCAP included 387 patients in one year. Maricq's active and Cutolo's late classifications were very similar. In multivariate analysis, the number of digital ulcers (OR for 2 ulcers or more, respectively 2.023 [1.074-3.81] and 2.596 [1.434-4.699]) and Rodnan's skin score >15 (OR respectively 32.007 [6.457-158.658] and 18.390 [5.380-62.865]) correlated with Maricq's active and Cutolo's late stages. Haemoglobin rate correlated with Cutolo's late stage (hemoglobin<100 vs. >120 g/dl: OR 0.223 [0.051-0.980]), and total lung capacity with Maricq's active one: increase in 10%: OR0.833 [0.717-0.969]. CONCLUSIONS: The correlations found between capillaroscopy and severity of SSc are promising before the ongoing prospective study definitively assesses whether capillaroscopy staging predicts complications of SSc. Only two capillaroscopic patterns seem useful: one involving many giant capillaries and haemorrhages and the other with severe capillary loss.

ABSTRACT

Objectives: Subgroups of capillaroscopic scleroderma landscape have been correlated with stages of SSc: two groups for Maricq's classification (slow and active), and three for Cutolo's classification (early, active and late). We report inter- and intra-observer agreement for these classifications as a preliminary step in the multicentre prospective SCLEROCAP study, which aims to assess the classification and single capillaroscopic items as prognostic tools for SSc. Methods: SCLEROCAP included 385 patients. Agreement was studied in the first 100 patients, who were independently rated twice by two observers, blind to patients' characteristics; 30 of the patients were rated once by six observers. After consensus meetings, these ratings were held again. Kappa and intraclass correlation coefficients were used to assess agreement. Results: Interobserver agreement on 100 patients was moderate for Maricq and Cutolo classifications [κ 0.47 (0.28, 0.66) and 0.49 (0.33, 0.65), respectively], and became substantial after consensus meetings [0.64 (0.50, 0.77) and 0.69 (0.56, 0.81)]. Intra-observer agreement between two observers was moderate to substantial: κ 0.54 (0.33, 0.75) and 0.70 (0.57, 0.83) for Maricq's classification; 0.57 (0.38, 0.77) and 0.76 (0.65, 0.87) for Cutolo's. Thirty patients were rated once by each of six observers, and agreement was moderate to substantial: κ 0.57 ± 0.10 (Maricq) and 0.61 ± 0.12 (Cutolo). Agreement was substantial for bushy, giant capillaries and microhaemorrhages, moderate for capillary density and low for oedema, disorganization and avascular areas. Conclusion: The moderate reproducibility of Maricq and Cutolo classifications might hamper their prognostic value in SSc patients. Consensus meetings improve reliability, a prerequisite for better prognostic performances. A focus on giant capillaries, haemorrhages and capillary density might be more reliable.

ABSTRACT

Objectives: The aim of this work was to study inter- and intra-observer agreement for the diagnosis of scleroderma pattern by wide-field capillaroscopy. Methods: Images were taken from 50 patients known to have SSc and 50 controls consulting for RP who did not have SSc. These images were rated simultaneously by 11 experienced vascular medicine physicians as scleroderma pattern or not. Two weeks later, 7 of the 11 observers again rated the same images. Results: Inter-observer agreement was almost perfect between the 11 observers (κ 0.86 ± 0.01), and the proportion of concordant observations was 79% (70-87). When each observer was compared with the reference, agreement was also almost perfect: κ coefficient 0.92 ± 0.03 and proportion of concordant observations 79% (70-87). Intra-observer agreement was also almost perfect: median κ coefficient 0.94 (0.78-0.96) and median proportion of concordant observations 97% (89-98). Conclusion: Excellent inter- and intra-observer agreement was obtained in experienced vascular physicians for the diagnosis of capillaroscopic landscape by wide-field nailfold capillary microscopy.
