RESUMEN
OBJECTIVE: Patients with Critical Limb Ischemia (CLI) present a high risk of cardiovascular events and death. Revascularization is the cornerstone of therapy to relieve ischemic pain and prevent limb loss. Literature data suggest that women tend to present with worse outcomes after revascularization. The aim of the present study is to determine amputation-free survival in a long-term follow-up in women and men following endovascular revascularization procedure for CLI. METHODS: From November 2013 to December 2020, 357 consecutive patients were retrospectively included. Clinical and biological parameters were recorded at baseline before endovascular revascularization. During follow-up until February 2023, overall survival and amputation-free survival (freedom from major amputation) were analysed using the Kaplan-Meier method. Univariate and multivariate analyses were performed to study the parameters associated with amputation-free survival. A P<0.05 was considered as statistically significant. RESULTS: A total of 357 consecutive patients were included, 189 men and 168 women with CLI, with a mean age of 78.6±12 years. Treated hypertension (79%), diabetes mellitus (48%), coronary artery disease (39%) and protein malnutrition (61%) were the most prevalent comorbidities. Women were older than men with a mean age of 82.4±11.4 years (versus 75.4±11 years in men) and presented more frequently with protein malnutrition (70% of women). Prevalence of diabetes, tobacco use and history of coronary heart disease were significantly higher in men. During the 10-year follow-up period, 241 patients had died (68%) and 38 (11%) underwent major amputation, of whom 22 patients were still alive on February 2023. Median survival was 35.5 months [IQR: 29.5; 43] in the overall population, 38.5 [32; 50.4] months in women and 33.5 months [24.7; 43.5] in men. No gender-related differences were noted according to peri-procedural complications, survival probability and amputation-free survival. In multivariate analysis for amputation-free survival, age, previous coronary heart disease, C-reactive protein level, left ventricular ejection fraction (LVEF)<60% and albumin level<35g/L were correlated with poor outcome. In particular, protein malnutrition, as a treatable risk factor, appears significantly correlated with poor outcome in both men and women (HR=2.50 [1.16;5.38], P=0.0196 in men; HR=1.77 [1.00;3.13], P=0.049 in women). CONCLUSION: The present results highlight that mortality in patients after endovascular revascularization remains high with a mortality rate of 28% at 1 year, 40% at 2 years and 51% at 3 years. Women represented a distinct population, almost 10-year older than their male counterparts, with more prevalent protein malnutrition. However, no gender-related difference was noted according to amputation-free survival on the long-term follow-up. Associated risk factors are mainly age, a history of coronary heart disease, pre-procedural inflammatory syndrome and protein malnutrition. Correction of malnutrition could have the potential to improve functional and general long-term prognosis in patients with CLI together with optimal medical and interventional management.

OBJECTIVE: Revascularization procedures are considered the cornerstone of therapy in patients with critical limb ischemia (CLI) and multiple procedures are often required to attain limb salvage. The aim of the present study is to determine the prevalence of peri-procedural complications after endovascular procedure, and to determine the clinical and biological characteristics of patients associated to the risk of peri-procedural complications. METHODS: From November 2013 to May 2021, 324 consecutive patients were retrospectively included, of whom 99 underwent more than one revascularization procedure for contralateral CLI or clinical recurrence of CLI. A total of 532 revascularizations were performed. Clinical and biological parameters were recorded at baseline before endovascular revascularization. The occurrence of a peri-procedural complication (local complications, fatal and non-fatal major bleeding or cardiovascular events) was recorded up to 30days after revascularization. Univariate and multivariate analyses were performed to study the parameters associated with per-procedural complications. A P<0.05 was considered as statistically significant. RESULTS: A total of 324 consecutive patients were included, 177 men and 147 women with CLI, with a mean age of 77.6±11.9years. Most of these patients had cardiovascular comorbidities (41% with a history of coronary heart disease, 78% treated hypertensive patients, 49% diabetic patients). Peri-procedural mortality occurred in 13 patients (4%) and 9 patients (2.8%) experienced major amputation at one-month following revascularization. Among the 532 revascularization procedures, 99 major bleeding events (22.8% of the cohort population) and 31 cardiovascular events (8.6% of the cohort population), were recorded in the peri-procedural period. Cardiovascular events were associated with peri-procedural mortality. Complications at the puncture site occurred during 38 of the 532 procedures (10.2% of the cohort population). Compared with patients undergoing a single revascularization procedure, patients with multiple procedures presented a higher risk of major bleeding events (48.5% vs. 11.6%, P<0.0001) and access site complications (20.2% vs. 5.78%, P<0.0001). In multivariate analysis, pulse pressure <60mmHg and hemoglobin level <10g/dl were correlated with the occurrence of major bleeding events; left ventricular ejection fraction<60% and the absence of statin treatment were correlated with the occurrence of cardiovascular complications; a high chronological rank of revascularization was correlated with the occurrence of local complication. Finally, age and gender were not associated with the occurrence of peri-procedural complication. CONCLUSION: The present results highlight that multiple revascularization procedures for limb salvage are required in almost one third of the population with critical limb ischemia and were associated with the risk of major bleeding events and access site complications. The most frequent complications of peripheral vascular interventions were major bleeding events. Adverse cardiovascular events were related with peri-procedural mortality. Anemia, blood pressure, left ventricular ejection fraction and statin treatment are important parameters to consider for peri-procedural outcomes, independently of age, gender and the chronological rank of revascularization procedure.

INTRODUCTION: Cutaneous and vascular manifestations of cancer are numerous. Among paraneoplastic acral vascular syndrome, we report a case of blue toe syndrome as the first manifestation of a prostate cancer following with analysis of this syndrome according literature. OBSERVATION: A 56-year-old man, with Raynaud's phenomenon of the upper limbs for 2 to 3 years, had 4 blue toes of the left foot evolving for 18 months, without ulceration, the pulses being present. Vascular and cardiac explorations (ultrasound, angio-MRI) were normal. There was no biological or immunological abnormality except an elevated PSA level. Prostate biopsies confirmed diagnosis and abdomino-pelvic CT scan proved the bone and lymph node metastasis. CONCLUSION: The revelation of a prostate cancer with bone metastases by a blue toe syndrome is a rare situation. In a patient with a blue toe syndrome with no obvious clinical or biological abnormality, especially atheromatous, investigations should include a search for cancer, which can be revealed by blue toes.

We report the case of a 51-year-old patient who presented necrosis affecting all of the toes in a context of confusion and declining general health. The etiology work-up disclosed a lung mass. Biopsy and search for extension led to the diagnosis of adenocarcinoma with liver metastasis. Unfortunately, symptomatic treatment of the digital necrosis did not lead to improvement and the patient was given palliative care. Digital necrosis generally affects the fingers. Localization on the toes is atypical and few cases have been reported in the literature.

Venous thromboembolism (VTE) is a frequent and serious complication in cancer patients, and the second leading cause of death in this setting. Cancer patients are also more likely to present recurrent VTE and major bleeding while taking anticoagulants. Management of VTE in these patients is always challenging and remains suboptimal worldwide. In 2013, the International Initiative on Thrombosis and Cancer (ITAC-CME) released international guidelines for the treatment and prophylaxis of VTE and central venous catheter-associated thrombosis, based on a systematic review of the literature ranked according to the Grading of Recommendations Assessment, Development, and Evaluation scale. An update of these ITAC-CME consensus guidelines, including the use of direct oral anticoagulants, was recently published. In this review, we summarize these updated guidelines. Better adherence to the international guidelines, involving an adequate educational and active implementation strategies, will substantially decrease the burden of VTE and allow to increase survival in cancer patients.

UNLABELLED: Skin leg ulcers are chronic painful wounds. The treatment of these ulcers is crucial for patients because pain has a significant impact on their daily lives. The analgesic effect of punch skin grafting (PSG) for the treatment of painful ulcers is not well described. The objective of the study is to assess the level of pain in patients with an ulcerated wound and to see if there is an analgesic effect of PSG. PATIENT AND METHODS: A single-center, non-interventional study conducted in hospitalized patients with one or several ulcer(s) of any type and which has been painful for more than six weeks. Pain was assessed before, the day after a PSG and then on the way out of hospital by a questionnaire and a numeric pain rating scale. Permanent pain and pain peaks were identified. RESULTS: Forty-one patients were included (23 men and 18 women) with a mean age of 73±21 years, 36% (n=15) with arterial ulcers, 36% (n=15) with venous ulcers, 12% (n=5) with necrotic angiodermatitis, 12% (n=5) with mixed ulcers and 4% (n=2) with "other ulcers" (due to infection and use of hydroxycarbamide). On day 1 of PSG, patients showed an improvement in terms of permanent pain (77%, n=24/31) and pain peaks (90%, n=37/41) respectively and 90% (n=28/31) and 95% (n=39/41) on the last day at hospital. Reduction in the use of strong opioids was found in 13 patients (81%). CONCLUSION: Punch skin grafting is a simple and validated treatment, which can reduce or eliminate pain related to ulcers. It has an effect on permanent pain and pain peaks. Its efficiency is particularly demonstrated on venous ulcers and mixed ulcers but also initially painful ulcers such as necrotic angiodermatitis or arterial ulcers.

OBJECTIVES: Determine whether general practitioners have sufficient expertise in the field of leg ulcers. METHOD: A cross-sectional survey was conducted among 179 general practitioners working in the region Île-de-France to evaluate the implementation of leg ulcer guidelines issued by the Superior Health Authority (HAS) in 2006. Participating physicians were either internship supervisors or practitioners in Paris' 14th district. RESULTS: The first hundred usable answers (response rate 65%) came from 71 internship supervisors and 29 practitioners of Paris' 14th district. Only 40% of the physicians were aware of the guidelines, with no significant difference noted between the two groups. 9/10 practitioners examined less than 10 patients with leg ulcers per year. Physical examinations were done according to the guidelines and a venous Doppler was prescribed in two thirds of the cases. The ankle-brachial pressure index (ABPI) essential to diagnose lower limb arteriopathy was measured for only 10% of the patients. In accordance with the guidelines, compression was by far (73%) considered as the main treatment as compared to dressing (37%), but compression therapy was well prescribed in only one-third of the cases. Despite poor prognosis criteria (characteristic and time course), referral for a specialized opinion was rare. CONCLUSION: Even if they were not always aware of the detailed guidelines, the practitioners applied the main recommendations. Nevertheless, practices could be improved by measuring the ABPI, searching for a diagnosis of arteriopathy, and better prescription of compression therapy. General practitioners should refer patients with leg ulcers to a specialized hospital unit.

UNLABELLED: Negative BCR ABL myeloproliferative neoplasm (MPN) such as polycythemia vera (PV), essential thrombocythemia (ET) and primary myelofibrosis (MFP) are clonal hematological malignancies and may lead to a high risk of venous, arterial or microcirculatory thrombosis. Atypical sites of thrombosis can sometimes reveal the neoplasm disorder. Their diagnoses are a major issue because of the propensity to develop acute myeloid leukemia and/or myelofibrosis. The acquired JAK2V617F variant (Janus kinase 2; 9p24) is a prevalent MPN and also a sensitive marker for PV diagnosis (95% positive mutation), but not specific since found in approximately 50% of patients with ET and MFP. PATIENT AND METHODS: We present a diagnostic and a therapeutic approach based on one patient with microcirculatory ischemic manifestations in the toes, and who had strictly normal cell blood counts and was positive for JAK2V617F mutation: thrombotic risk factor evaluation; bone marrow biopsy; red cell adhesion assays. These experimental assays are promising for the development of new therapeutics in MPN; they assess red cell adherence to the vascular endothelium after the phosphorylation of Lu/BCAM subsequent to a positive JAK2V617F mutation. RESULTS: Compared with controls, our patient exhibited increased Lu/BCAM receptor phosphorylation and red blood cell adhesion. CONCLUSION: This development may lead to improved care for patients with thrombotic manifestations, normal blood cell counts, and a positive JAK2V617F mutation: multidisciplinary management, including regular hematological monitoring, could lead to the introduction of a cytoreductive treatment.

OBJECTIVE: To evaluate compression therapy for venous leg ulcers in terms of adherence, acceptability, quality, and effectiveness. DESIGN OF STUDY: Prospective observational cohort study. SETTING: Vascular diseases outpatient clinic in Paris, France. SUBJECTS: One hundred consecutive patients with active or healed leg ulcers and chronic lower limb venous insufficiency stage C5 or C6 in the CEAP classification scheme. INTERVENTIONS: Compression systems applied in a community-based practice. MAIN OUTCOME MEASURES: A standardized form was used to collect: (1) data on patient adherence; (2) objective criteria evaluating the quality, effectiveness, and correct application of compression systems and; (3) patient education and perceptions about their compression therapy. RESULTS: Patient adherence with compression therapy was high (89%), even though it was often a source of discomfort. Only 10% of patients signaled no discomfort. Drawbacks reported by patients were excessive warmth (29%), pruritus (33%), unacceptably high cost (48%), and moderate to considerable difficulty putting on footwear (64%). In the 11% of patients who did not wear their compression system, reasons for nonadherence were inadequate comprehension of expected benefits (45.5%), pain related to compression (36.4%), difficulty applying the compression system (27.3%), and difficulty putting on footwear (27.3%). Application was correct in 51.7% of adherent patients; errors in the remaining patients included slippage, failure of the bandage to extend to just under the knee (55.8%), a tourniquet effect (21%), failure of bandaging starting at the base of the toes (37.2%), and failure to cover the heel (53.5%). Full edema control was achieved in 51.7% of adherent patients. Compression was adequate overall (worn, correctly applied, and effective) in 49% of adherent patients. The most common reasons for lack of effectiveness were inadequate pressure and errors in application. Lack of awareness of potential benefits and wearing modalities of compression therapy was noted in 56% of patients. CONCLUSION: Patients, nurses, and physicians have inadequate knowledge of the modalities of compression therapy and as a result they are not well respected. Educational programs are needed.

Kikuchi disease is a rare entity characterized by lymphadenopathy and fever. Pathology study of lymph node biopsies provides the diagnosis. The disease course is favorable. The disease can occur isolated, or associated with other pathologies including lupus or mixed connective tissue disease. We report a case of Kikuchi disease in a 35-year-old woman, occurring 12 years after the diagnosis of overlap syndrome with antiphospholipid antibodies. The patient was given prednisone 25mg per day and long-term hydroxychloroquine. FDG PET/CT showed FDG-avidity nodular masses. After bolus corticosteroid therapy, outcome was favorable with disappearance of metabolic hyperactivity on the FDG PET/CT. The bolus prednisone treatment could then be discontinued. In the 61 cases of Kikuchi disease and lupus associations previously published, Kikuchi disease was diagnosed after lupus in only 13 % of the observations. In these cases, use of FDG PET/ CT was not reported. For us, FDG PET/CT was useful for diagnosis, for choosing the biopsy site and for follow-up.

International guidelines on leg ulcers recommend measuring the ankle arm index (AAI) to diagnose and assess peripheral arterial occlusive disease (PAOD) of the lower limbs. These guidelines do not, however, describe the method which should be used to make the measurement: which artery should be measured -in the event of an open leg ulcer, what are the practical difficulties for positioning the cuff- how well do patients tolerate the procedure? We conducted a prospective study focusing on ease of use, tolerance and performance of AAI measurements in patients with leg ulcers. In compliance with recent French guidelines, we measured the AAI for both distal leg arteries and retained the lowest value for analysis. Within a six-month study period, 100 consecutive inpatients with leg ulcers of various etiologies were studied. Mean age was 75, female predominance 60%, body mass index 27. Etiologies of leg ulcers were pure venous (29%), mixed venous predominant (17%), pure arterial (9%), mixed arterial predominant (8%), mixed (6%), hypertensive ulcers (11%), rare cause (8%), multifactorial (12%). Pain was present in 92%, with a VAS above 3 for 73%. Measurement of AAI was possible in 98% of patients. It was too painful and thus considered unethical for two patients with hypertensive ulcers. For the 98 patients measured, the ulcer had to be protected during the measurement in 76%. The measurement procedure only took five minutes for one leg, and was judged easy to perform by 93% of the operators. For the majority (76%) of patients, the measurement was not painful. We determined the diagnostic performance of AAI by comparing the results with those of arterial ultrasound in 90 patients who had a complete arterial ultrasound exploration of the legs. Compared with arterial ultrasound, the sensitivity of AAI<0.9 for detecting the presence of PAOD was 84.7%, with 97% specificity. PAOD was not diagnosed in any patient who had two palpable distal pulses and a normal AAI. Measurement of AAI in patients with leg ulcers is an easy to use, well-tolerated, high-performance tool for the assessment of PAOD.

UNLABELLED: Vitamin C is a necessary cofactor for collagen synthesis. A deficiency of vitamin C results in the breakdown of connective tissue in and around the walls of blood vessels. The disease is thus characterized by poor healing of wounds. Chronic leg ulcers are defined as wounds that do not heal. OBJECTIVE: To investigate whether patients with chronic leg ulcers have vitamin C deficiency. METHODS: Case control study; vitamin C was assayed in peripheral blood samples of 42 consecutive patients with chronic leg ulcers and in 37 consecutive patients without chronic leg ulcers. Patients without leg ulcers had peripheral vascular disease, or hypertension, or connective disorders. Patients with diabetes, immunodepression (cancer, HIV infection, corticosteroid therapy) and aged under 65 years were excluded. Reference range for plasma vitamin C was above 26 micromol/l (normal levels, group I), hypovitaminosis C as 6-26 micromol/l (group II) and concentrations<6 micromol/l as scurvy (group III). RESULTS: Mean age was 77.2 years in the ulcers group and 73.8 in the control group (NS), mean weight 73.1 kg in the ulcers group and 67.5 kg in the control group (NS). Smoking was more frequent in the control group (P<0.001). Mean vitamin C levels were lower in the leg ulcers group: 23.9 vs 33.8 micromol/l (P<0.003). Normal levels of vitamin C (group I) were more frequent in the control group: 78.4 vs 50% (P<0.01). Hypovitaminosis C (group II) was more frequent in the leg ulcers group: 23.8 vs 16.2% (P<0.01). Scurvy was more frequent in the leg ulcers group: 26.2 vs 5.4% (P<0.01). C reactive protein levels were higher in the leg ulcers group: 31.8 vs 9.3 mg (P=0.002) and albumin levels were lower in the leg ulcers group: 25 vs 38 g/l (P=0.01) [retrospective data]. CONCLUSION: Patients with chronic leg ulcers have lower levels of vitamin C than patients without leg ulcers, although smoking was more frequent in patients without leg ulcers. The question is whether vitamin C deficiency is a cofactor of impaired healing or is a simple marker of poor healing? It would be interesting to conduct a randomized controlled study about treatment of chronic leg ulcers with vitamin C.

The aim of this study is to determine prevalence, clinical significance of antiphospholipid antibodies (aPL) including anticardiolipin antibodies (aCL), anti-beta2GP1 and lupus anticoagulant (LA) in a cohort of 74 patients with primary Sjögren's syndrome (pSS) according to revised European criteria. aPL were found in 25 (34%) patients; IgG in 23 (12 had low titres, six moderate titres and five high titres) and IgM in five (three and two had respectively moderate and high titres). Eight (11%) patients were found to have LA; anti-beta2GP1 antibodies were detected only in three (4%) patients. Only two patients with LA, aPL and beta2GP1 had recurrent venous thrombosis. One patient with moderate titres of aPL exhibited recurrent spontaneous foetal losses. Peripheral neuropathies without cryoglobulinemia were more frequent in the aPL group. Other systemic involvements of pSS were the same in both groups with or without aPL. Patients with aPL have more concurrent immunological diseases such as thyroiditis and primary biliary cirrhosis and a higher prevalence of hypergammaglobulinemia (P < 0.05). Even if aPL prevalence reached 30% in pSS, titres were usually low, with a close correlation with hypergammaglobulinemia but not with antiphospholipid syndrome, which is related to positivity of both LA and aPL.

PURPOSE: Rhabdomyolysis and myositis are rare, dose-related complications of statins and fenofibrates. The outcome is favorable as a rule with rapid regression after stopping the responsible drug. Recently, various auto-immune disease with evidence of hypersensitivity to HMG-CoA reductase inhibitors or fibrates drugs have been reported. Less than ten cases of dermatomyositis and polymyositis due to cholesterol-lowering drugs (CLD) have been previously reported. Five more cases polymyositis associated with CLD are reported. METHODS: Symptoms were compatible with diagnosis of polymyositis according to Bohan and Peter and with previous reported criteria for drug-induced myopathy in all cases. None of these patients had previous other connective tissue disorders. RESULTS: Five patients (median age 68 [54-78], female N =4) with CLD treatment (statin N =4, fenofibrates N =1) have developed iatrogenic polymyositis. All of them presented both proximal muscular weakness and increased muscle enzyme levels. One patient had iatrogenic antisynthetase syndrome characterized by mechanic's hand, Raynaud's phenomenon and anti JO1 antibodies. One other had sclerodermic hand oedema. Antinuclear antibodies were positive in 4 cases and muscle biopsy revealed polymyositis infiltrate in 4 cases. CLD treatment was discontinued with partial clinical improvement in 3 cases. Clinical remission was obtained with corticosteroid (N =5) in association with immunosuppresive agents in 3 cases.

OBJECTIVE: To evaluate patient compliance with drug therapy in temporal arteritis and to determine the characteristics of compliant or non-compliant patients. METHODS: Inpatients and outpatients from an Internal Medicine Unit were interviewed. Compliance with drug dosage and administration time was assessed with a questionnaire for the following drugs: glucocorticoids, calcium, vitamin D, diphosphonates (prevention of glucocorticoid-induced osteoporosis). RESULTS: Forty-nine patients were interviewed (61% female, mean age = 73.7 years). Glucocorticoids were prescribed to 96% of the patients, calcium and vitamin D to 86% and diphosphonates to 49%. Compliance with drug therapy was 87%, 60%, 68% and 51%, respectively, for all treatments. It was independent from the disease duration. Male were more compliant than female (P = 0.012). CONCLUSION: Half of the patients with temporal arteritis are non-compliant with drug therapy. The questionnaire is simple. It can be used in everyday clinical practice to study and improve patient compliance.

PURPOSE: Pregnancy complicated by the HELLP syndrome and antiphospholipid syndrome have rarely been reported. We report a study on anticardiolipin antibodies in HELLP syndrome. METHODS: Between March 1996 and September 1999, anticardiolipin antibodies were checked in all women with HELLP syndrome hospitalised in a maternity of the North of France. The women with positive anticardiolipin antibodies were seen month later in a internal medicine department. RESULTS: In the period 68 women with HELLP syndrome were checked for anticardiolipin antibodies. Apl were present in 9 patients (Incidence 42.8/1000 HELLP Year). They persisted after the accident only in 3 patients. Antiphospholipid syndrome was diagnosed in 2 patients, prevalence between the HELLP syndrome for the 42 month period was 0.03. CONCLUSIONS: HELLP syndrome may be a manifestation linked to the antiphospholipid syndrome and may revealed it.
