Predictors of recurrence of cancer-associated venous thromboembolism after discontinuation of anticoagulant therapy: a multicenter cohort study.

BACKGROUND: Data on recurrence after the end of anticoagulation for a first event of cancer-associated venous thromboembolism (VTE) are scarce. OBJECTIVES: Our aim was to assess predictors of VTE recurrence during a 1-year follow-up period. METHODS: This study is an analysis of RIETE, an international, multicenter, prospective cohort study of patients diagnosed with VTE. Patients had to have active cancer at the time of VTE and to have withdrawn from anticoagulation after 3 months of full treatment. Analyses were performed using Fine and Gray models, with death as a competing risk, and multiple imputation of missing data was performed by chained equations. RESULTS: Among 14 318 patients with cancer-associated VTE, 3414 had undergone time-limited anticoagulation for at least 3 months. The cumulative incidence function for recurrent VTE was 10.2% (95% CI, 9.1-11.5) at 1 year. Chronic kidney disease (a subhazard ratio [sHR] of 1.08 for 10-mL/min decrease in glomerular filtration rate; 95% CI, 1.02-1.14); cancer of the lung, brain, stomach, esophagus, liver, or ovary (sHR, 3.56; 95% CI, 1.07-11.80; compared with cancer of the oropharynx, larynx, or melanoma); cancer of the pancreas, the biliary tract, or of unknown origin (sHR, 6.86; 95% CI, 1.89-24.85); inferior vena cava filter (sHR, 3.16; 95% CI, 1.75-5.71); postthrombotic syndrome (sHR, 2.09; 95% CI, 1.06-4.15); and residual pulmonary thrombotic obstruction (sHR, 2.58; 95% CI, 1.38-4.82) were predictive of recurrence. Surgery during the 2 months before VTE was predictive of absence of recurrence (sHR, 0.60; 95% CI, 0.40-0.92). CONCLUSION: One year after anticoagulant cessation for cancer-associated VTE, approximately 10% of patients experienced recurrence. Discontinuing anticoagulant therapy seems safe, mainly in surgery-associated VTE.

Predictive Factors of Stent Patency in Iliofemoral Venous Diseases in a Multicentre Cohort Study.

OBJECTIVE: This study assessed primary stent patency predictive factors in three groups of patients with history of lower limb (LL) vein thrombosis: non-thrombotic iliac vein lesion (NIVL), acute deep vein thrombosis (aDVT), and post-thrombotic syndrome (PTS). METHODS: Consecutive patients from January 2014 to December 2020 with history of LL vein stenting from seven hospitals were included. All patients received an iliac or common femoral venous stent and had at least a six month follow up available with stent imaging. Anticoagulant and antiplatelet therapy strategies employed after venous stenting are reported and compared between groups. RESULTS: This study included 377 patients: 134 NIVL, 55 aDVT, and 188 PTS. Primary patency was statistically significantly higher in the NIVL group (99.3%) compared with the PTS group (68.6%) (p < .001) and the aDVT group (83.6%) (p = .002). PTS patients received a statistically significantly greater number of stents (p < .001) and had more stents below the inguinal ligament (p < .001). Median follow up was 28.8 months (IQR 16, 47). Discontinuation of antiplatelet therapy at the last assessment was 83.6% for NIVL, 100% for aDVT, and 95.7% for the PTS group (p < .001). Discontinuation of anticoagulation therapy at the last assessment was 93.2% for NIVL, 25.0% for aDVT, and 70.3% for the PTS group (p < .001). The only predictor of worse primary patency in the aDVT group was long term anticoagulation before stenting. CONCLUSION: Patients with NIVL have better primary patency after venous stenting than patients with venous thrombotic disorders. Long term anticoagulation before stenting was the only factor associated with poorer primary patency in patients with aDVT.

Inter and intra-observer agreement of arterial wall contrast-enhanced ultrasonography in giant cell arteritis.

Objective: The aim of this study was to analyze inter- and intra-observer agreement for contrast-enhanced ultrasonography (CEUS) for monitoring disease activity in Giant Cell Arteritis (GCA) in the wall of axillary arteries, and common carotid arteries. Methods: Giant cell arteritis patients have CEUS of axillary arteries and common carotid. These images were rated by seven vascular medicine physicians from four hospitals who were experienced in duplex ultrasonography of GCA patients. Two weeks later, observers again rated the same images. GCA patients were recruited in from December 2019 to February 2021. An analysis of the contrast of the ultrasound images with a gradation in three classes (grade 0, 1, and 2) was performed. Grade 0 corresponds to no contrast, grade 1 to moderate wall contrast and grade 2 to intense contrast. A new analysis in 2 classes: positive or negative wall contrast; was then performed on new series of images. Results: Sixty arterial segments were evaluated in 30 patients. For the three-class scale, intra-rater agreement was substantial: κ 0.70; inter-rater agreement was fair: κ from 0.22 to 0.27. Thirty-four videos had a wall thickness of less than 2 mm and 26 videos had a wall thickness greater than 2 mm. For walls with a thickness lower than 2 mm: intra-rater agreement was substantial: κ 0.69; inter-rater agreement was fair: κ 0.35. For walls with a thickness of 2 mm or more: intra-rater agreement was substantial: κ 0.53; inter-rater agreement was fair: κ 0.25. For analysis of parietal contrast uptake in two classes: inter-rater agreement was fair to moderate: κ from 0.35 to 0.41; and for walls with a thickness of 2 mm or more: inter-rater agreement was fair to substantial κ from 0.22 to 0.63. Conclusion: The visual analysis of contrast uptake in the wall of the axillary and common carotid arteries showed good intra-rater agreement in GCA patients. The inter-rater agreement was low, especially when contrast was analyzed in three classes. The inter-rater agreement for the analysis in two classes was also low. The inter-rater agreement was higher in two-class analysis for walls of 2 mm thickness or more.

Platelet Versus Megakaryocyte: Who Is the Real Bandleader of Thromboinflammation in Sepsis?

Platelets are mainly known for their key role in hemostasis and thrombosis. However, studies over the last two decades have shown their strong implication in mechanisms associated with inflammation, thrombosis, and the immune system in various neoplastic, inflammatory, autoimmune, and infectious diseases. During sepsis, platelets amplify the recruitment and activation of innate immune cells at the site of infection and contribute to the elimination of pathogens. In certain conditions, these mechanisms can lead to thromboinflammation resulting in severe organ dysfunction. Here, we discuss the interactions of platelets with leukocytes, neutrophil extracellular traps (NETs), and endothelial cells during sepsis. The intrinsic properties of platelets that generate an inflammatory signal through the NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome are discussed. As an example of immunothrombosis, the implication of platelets in vaccine-induced immune thrombotic thrombocytopenia is documented. Finally, we discuss the role of megakaryocytes (MKs) in thromboinflammation and their adaptive responses.

Correlation of nailfold capillaroscopy findings with history of digital ulcer on same finger: Results of SCLEROCAP study.

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.

Comparison between conventional duplex ultrasonography and the dual-gate Doppler mode for hemodynamic measurements of the carotid arteries.

PURPOSE: This study investigated the correlations of hemodynamic parameters measured to quantify stenosis between the gold-standard duplex ultrasonography and the dual-gate Doppler mode. METHODS: Patients examined due to suspicion of carotid artery stenosis or for surveillance of known stenosis were invited to participate in this prospective single-center study. Upon acceptance, the hemodynamic characteristics of the carotid arteries were determined successively in standard duplex and dual-gate Doppler modes. The correlations between the two modes were analyzed by computing Pearson coefficients (r2) and Lin concordance coefficients (ρc). The degree of agreement between the two methods was visualized using Bland-Altman graphical representations. RESULTS: The correlation between internal carotid artery peak systolic velocity measured by standard duplex ultrasonography and dual-gate Doppler mode was good (r2=0.642). The same high level of correlation was observed for the carotid ratio (r2=0.544). However, the Bland-Altman graphical representation and the Lin concordance coefficients (ρc=0.75 and ρc=0.74 for the internal carotid artery peak systolic velocity and carotid ratio, respectively) showed that a lack of precision generated some discrepancies between the two measurement methods. CONCLUSION: Although some discrepancies were observed, the hemodynamic measurements were closely correlated between the two ultrasonography modes. Therefore, the dual-gate Doppler mode may have obvious advantages over conventional ultrasonography, offering interesting development possibilities.

Finger Systolic Blood Pressure Index Measurement: A Useful Tool for the Evaluation of Arterial Disease in Patients With Systemic Sclerosis.

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.

Mortality, Cardiovascular and Limb Events in Patients With Symptomatic Lower Extremity Artery Disease and Diabetes.

The aim of this study was to compare the prognosis of patients according to diabetes status, during a 1-year follow-up after hospital admission for lower extremity artery disease, in the prospective COPART (COhorte de Patients ARTériopathes) registry. Inclusion criteria were intermittent claudication, ischemic rest pain, tissue loss, or acute limb ischemia, with radiological and hemodynamic confirmation. Among 2494 patients, 1235 (49.5%) had diabetes. Incidence rates for major adverse cardiovascular events (MACE) were 18.0/100 person-years (95% confidence interval [CI], 15.4-21.0) for the diabetes group and 11.1/100 person-years (95% CI, 9.2-13.4) for the non-diabetes group. Incidence rates of all-cause mortality were 29.8/100 person-years (95% CI, 26.5-33.4) for the diabetes group and 19.7/100 person-years (95% CI, 17.2-22.7) for the non-diabetes group. Incidence rates of major limb amputation were 24.2/100 person-years (95% CI, 21.1-27.8) for the diabetes group and 11.6/100 person-years (95% CI, 9.6-14.0) for the non-diabetes group. Diabetes was associated with MACE, adjusted hazard ratio 1.60 (95% CI, 1.16-2.22), and all-cause mortality, unadjusted HR 1.49 (95% CI, 1.24-1.78). In the multivariate analysis, diabetes was no longer associated with major amputation, adjusted HR 1.15 (95% CI, .87-1.51). Patients hospitalized for LEAD with diabetes had a higher risk of MACE than those without diabetes.

Presentation and Real-World Management of Giant Cell Arteritis (Artemis Study).

Background: Few studies of daily practice for patients with giant cell arteritis (GCA) are available. This French study aimed to describe the characteristics and management of GCA in a real-life setting. Methods: Cross-sectional, non-interventional, multicenter study of patients ≥50 years old who consulted hospital-based specialists for GCA and were under treatment. Patient characteristics and journey, diagnostic methods and treatments were collected. Descriptive analyses were performed. Results: In total, 306 patients (67% females, mean age 74 ± 8 years old) were recruited by 69 physicians (internists: 85%, rheumatologists: 15%); 13% of patients had newly diagnosed GCA (diagnosis-to-visit interval <6 weeks). Overall median disease duration was 13 months (interquartile range 5-26). Most patients were referred by general practitioners (56%), then ophthalmologists (10%) and neurologists (7%). Most common comorbidities were hypertension (46%), psychiatric disorders (10%), dyslipidemia (12%), diabetes (9%), and osteoporosis (6%). Initial GCA presentations included cranial symptoms (89%), constitutional symptoms (74%), polymyalgia rheumatica (48%), and/or other extra-cranial manifestations (35%). Overall, 85, 31, 26, and 30% of patients underwent temporal artery biopsy, high-resolution temporal artery Doppler ultrasonography, 18FDG-PET, and aortic angio-CT, respectively. All patients received glucocorticoids, which were ongoing for 89%; 29% also received adjunct medication(s) (methotrexate: 19%, tocilizumab: 15%). A total of 40% had relapse(s); the median time to the first relapse was 10 months. Also, 37% had comorbidity(ies) related to or aggravated by glucocorticoids therapy. Conclusion: This large observational study provides insight into current medical practices for GCA. More than one third of patients had comorbidities related to glucocorticoid therapy for a median disease duration of 13 months. Methotrexate and tocilizumab were the most common adjunct medications.

Triaging acute pulmonary embolism for home treatment by Hestia or simplified PESI criteria: the HOME-PE randomized trial.

AIMS: The aim of this study is to compare the Hestia rule vs. the simplified Pulmonary Embolism Severity Index (sPESI) for triaging patients with acute pulmonary embolism (PE) for home treatment. METHODS AND RESULTS: Normotensive patients with PE of 26 hospitals from France, Belgium, the Netherlands, and Switzerland were randomized to either triaging with Hestia or sPESI. They were designated for home treatment if the triaging tool was negative and if the physician-in-charge, taking into account the patient's opinion, did not consider that hospitalization was required. The main outcomes were the 30-day composite of recurrent venous thrombo-embolism, major bleeding or all-cause death (non-inferiority analysis with 2.5% absolute risk difference as margin), and the rate of patients discharged home within 24 h after randomization (NCT02811237). From January 2017 through July 2019, 1975 patients were included. In the per-protocol population, the primary outcome occurred in 3.82% (34/891) in the Hestia arm and 3.57% (32/896) in the sPESI arm (P = 0.004 for non-inferiority). In the intention-to-treat population, 38.4% of the Hestia patients (378/984) were treated at home vs. 36.6% (361/986) of the sPESI patients (P = 0.41 for superiority), with a 30-day composite outcome rate of 1.33% (5/375) and 1.11% (4/359), respectively. No recurrent or fatal PE occurred in either home treatment arm. CONCLUSIONS: For triaging PE patients, the strategy based on the Hestia rule and the strategy based on sPESI had similar safety and effectiveness. With either tool complemented by the overruling of the physician-in-charge, more than a third of patients were treated at home with a low incidence of complications.

Editor's Choice - External Applicability of the COMPASS and VOYAGER-PAD Trials on Patients with Symptomatic Lower Extremity Artery Disease in France: The COPART Registry.

OBJECTIVE: The aim of this study was to examine the external applicability of the COMPASS and the VOYAGER-PAD trials in patients with lower extremity artery disease (LEAD) in the real world. METHODS: This was a multicentre retrospective analysis of prospectively collected COPART data, a French multicentre registry of patients hospitalised for symptomatic LEAD. The proportion of patients eligible for the combination of rivaroxaban 2.5 mg twice daily plus aspirin based on either COMPASS or VOYAGER-PAD criteria is reported. The one year cumulative incidence of outcomes between eligible and non-eligible patients, as well as eligible patients vs. control arms of the COMPASS (LEAD patient subgroup) and the VOYAGER-PAD trials were compared. Analyses were performed using Cox models. RESULTS: Of 2 259 evaluable patients, only 679 (30.1%) were eligible for a low dose rivaroxaban plus aspirin regimen. Others were not eligible because of the need for anticoagulant (48.5% and 38.9% of patients meeting COMPASS and VOYAGER-PAD exclusion criteria, respectively) or dual antiplatelet therapy use (15.7% and 16.5%, respectively), high bleeding risk (14.4% and 11.6%, respectively), malignancy (26.1% and 21.0%, respectively), history of ischaemic/haemorrhagic stroke (21.1% and 19.8%, respectively), and severe renal failure (13.2% and 10.5%, respectively). COMPASS and VOYAGER-PAD eligible and ineligible patients were at higher risk of ischaemic events than participants in these trials. The one year cumulative incidences were 6.0% (95% CI 4.3 - 8.1) in the COMPASS eligible subset vs. 3.5% (95% CI 2.9 - 4.3) in the COMPASS control arm for major adverse cardiovascular events, and 27.9% (95% CI 19.9 - 38.3) in the VOYAGER-PAD eligible subset vs. 6.0% (95% CI 5.3 - 6.9) in the VOYAGER-PAD control arm for major adverse limb events. CONCLUSION: Many patients hospitalised for symptomatic LEAD in France are not eligible for the low dose rivaroxaban plus aspirin combination. In turn, those eligible may potentially have greater absolute benefit because of higher risk than those enrolled in the trials.

Impact of angiotensin receptor blockers on mortality after hospitalization for symptomatic lower extremity artery disease.

AIMS: The objective was to assess the association between angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) prescription at discharge in patients hospitalized for symptomatic lower extremity artery disease (LEAD) and 1-year mortality. METHODS AND RESULTS: The COPART registry is a multicentre, prospective, observational, cohort study which includes consecutive patients hospitalized for symptomatic LEAD in four French academic centres. All-cause mortality during a 1-year follow-up after hospital discharge was compared between patients with ARB, patients with ACEI and patients without ARB or ACEI. Analyses were performed using Cox models. As a sensitivity analysis, a propensity score (PS)-matching analysis was carried out. Among 1981 patients, 421 had ARB (21.3%), 766 ACEI (38.7%), and 794 no ACEI/ARB (40.1%) at discharge. During the 1-year follow-up, incidence rates for mortality were 12.6/100 person-years [95% confidence interval (CI) 9.7-16.1] for patients with ARB, 15.8/100 person-years (95% CI 13.4-18.6) for patients with ACEI and 19.8/100 person-years for patients without ACEI/ARB (95% CI 17.2-22.8). In a multivariate Cox model, ARB at discharge was associated with decreased mortality compared with no ACEI/ARB, hazard ratio (HR) 0.68 (95% CI 0.49-0.95), and with ACEI, HR 0.69 (95% CI 0.49-0.97). These results are consistent with those obtained by the Cox analyses in the PS-matched sample: HR 0.68 (95% CI 0.47-0.98) for patients with ARB compared with no ARB. CONCLUSION: Angiotensin receptor blockers at discharge after hospitalization for symptomatic LEAD is associated with a better survival compared with ACEI or no ACEI/ARB.

Lower limb venous and arterial peripheral diseases and work conditions: systematic review.

OBJECTIVES: The individual peripheral vascular disease risk factors are well documented, but the role of work conditions remains equivocal. This systematic review aims to assess relationships between lower limb peripheral venous diseases (lower limb varicose veins (LLVV), venous thromboembolism (VTE) comprising deep vein thrombosis and pulmonary embolism), peripheral arterial disease (intermittent claudication, aortic dissection, aortic aneurysm) and occupational constraints among working adults. METHODS: Several databases were systematically searched until February 2019 for observational studies and clinical trials. Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was used for article selection. Quality assessment and risk of bias were evaluated using Strengthening the Reporting of Observational Studies in Epidemiology and Newcastle-Ottawa scales. RESULTS: Among the 720 screened articles, 37 remained after full-text evaluation. Among the 21 studies on LLVV, prolonged standing was significantly associated to a higher risk of varicose veins with a threshold probably around >3 to 4 hours/day but exposure duration in years was not sufficiently considered. Seated immobility was often observed in workers, with no sufficient evidence to prove that prolonged sitting at work is related to VTE. Carrying heavy loads, stress at work and exposure to high temperatures have emerged more recently notably in relation to varicose veins but need to be better explored. Only three studies discussed the potential role of work on peripheral arterial disease development. CONCLUSIONS: Although some observational studies showed that prolonged standing can be related to varicose veins and that seated immobility at work could be linked to VTE, very little is known about peripheral arterial disease and occupational constraints. Clinical trials to determine preventive strategies at work are needed. PROSPERO REGISTRATION NUMBER: CRD42019127652.

Evolution of Major Amputation Risk in Patients Hospitalized in France for Critical Limb Ischemia: The COPART Registry.

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.

Systematic Screening for Deep Vein Thrombosis in Critically Ill Inpatients With COVID-19: Impact on the Incidence of Venous Thromboembolism.

Background: Several studies suggest an increased incidence of thrombosis in COVID-19 patients. However, evidence on how to prevent and even treat it is scarce. The aim of this study was to compare the cumulative incidence of venous thromboembolism (VTE) of two different methods for lower extremity deep vein thrombosis (LE-DVT) diagnosis: systematic vs. clinically guided complete compression venous ultrasonography (CCUS). We conducted a monocentric, prospective, open-label, non-randomized study. All consecutive patients admitted in three intensive care units (ICUs) of University Hospital of Toulouse for COVID-19 pneumonia were included: one performed systematic screening for LE-DVT, the others did not. The primary outcome was the 21-day cumulative incidence of VTE. The secondary end points were the 21-day cumulative incidences of major bleeding and death. Results: Among the 78 patients included, 27 (34.6%) underwent systematic screening for DVT 7 ± 2 days after ICU admission. Thirty-two patients (41.0%) were diagnosed with VTE, with a 21-day cumulative incidence of 42.3% (95% CI, 31.4-55.2), without difference between screened and non-screened patients (hazard ratio 1.45, 95% CI, 0.72-2.93). In the screened group, the frequency of isolated DVT was higher (25.9 vs. 5.9%, p-value = 0.027), but the frequency of pulmonary embolism was not reduced (25.9 vs. 29.4%, p-value = 0.745). The 21-day cumulative incidences of major bleeding and death were 9.6% (95% CI, 4.7-19.2) and 10.3% (95% CI, 5.0-20.8), respectively, without difference between the two groups. Conclusions: A systematic screening for DVT in patients hospitalized in ICU was not associated with a higher diagnosis of VTE or a reduced diagnosis of PE.

Correlation between capillaroscopic classifications and severity in systemic sclerosis: results from SCLEROCAP study at inclusion.

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.

Juvenile temporal arteritis: A clinicopathological multicentric experience.

INTRODUCTION: Juvenile temporal arteritis (JTA) is a recently-described and little-known inflammatory disease and its etiology is undetermined. Less than forty cases have been published. This paper is aimed at reporting the largest JTA series and to compare it to literature data to better evaluate its characteristics at diagnosis, its evolution and treatment options. MATERIAL AND METHODS: We conducted a retrospective and descriptive multicentric study in France by identifying adult patients under the age of 50 which had a pathological temporal artery biopsy owing to the presence of a temporal arteritis. Patients with temporal arteritis as a manifestation of systemic vasculitis were excluded. RESULTS: We included 12 patients and the literature review identified 32 cases described in 27 articles, thus a total of 44 patients - 34 men and 10 women - with a median age of 30 and a maximum of 44. All patients presented either a lump in the temporal region or prominent temporal arteries, and 47.7% of patients suffered from headaches. Only 11.4% of patients presented general symptoms and 6.8% a biological inflammatory syndrome; 34.1% had peripheral blood eosinophilia; 83.7% presented a single episode and complete excision without further treatment was documented for 72.7%. Pathology analysis revealed infiltrate of inflammatory cells in the arterial wall in 97.6% of patients but also sparse giant cells for 25% and granuloma for 22.9%, perivascular extension of the inflammation for 82.6%, and presence of lymphoid follicles or germinal centres for 60%. Clinical relapses were present in 16.3% of cases. CONCLUSION: JTA is a rare, localized and benign disease. The majority of cases have only one episode which is cured by local surgery.

Comparison of Ankle Pressure, Systolic Toe Pressure, and Transcutaneous Oxygen Pressure to Predict Major Amputation After 1 Year in the COPART Cohort.

The hemodynamic definition of critical limb ischemia (CLI) has evolved over time but remains controversial. We compared the prediction of major amputation by 3 hemodynamic methods. Patients were selected from the Cohorte des Patients ARTériopathes cohort of patients hospitalized for peripheral arterial disease. Patients with CLI were enrolled according to the Trans-Atlantic Inter-Society Consensus Document on Management of Peripheral Arterial Disease II definition and followed up for at least 1 year. We compared the major amputation rate according to initial ankle pressure (AP), systolic toe pressure (STP), and forefoot transcutaneous oxygen pressure (TcPO2); 556 patients were included and divided into surgical (264) and medical (292) groups. The AP failed to identify 42% of patients with CLI. After 1 year, 27% of medical and 17% of surgical patients had undergone major amputation. The TP <30 mm Hg predicted major amputation in the whole sample and in the medical group (odds ratio [OR] 3.5 [1.7-7.1] and OR 5 [2-12.4], respectively), but AP did not. The TcPO2 <10 mm Hg also predicted major amputation (OR 2.3 [1.5-3.5] and OR 3.8 [2.1-6.8]). The best predictive thresholds to predict major amputation were STP <30 mm Hg and TcPO2 <10 mm Hg. None of these methods performed before surgery was able to predict outcome in the revascularized patients.
