[Gastrointestinal tract involvement in systemic sclerosis]. / Atteinte digestive de la sclérodermie systémique.

Gastrointestinal tract involvement in systemic sclerosis concerns more than 90% of patients but is of heterogeneous clinical expression. It can involve the entire intestinal tract and be responsible for multifactorial malnutrition, which is frequent in this disease. It is a major source of deterioration in the quality of life and can even be life-threatening. Management is complex and multidisciplinary, ranging from simple hygienic and dietary measures, to specialized endoscopic or surgical interventional procedures, also including medical treatments, particularly proton pump inhibitors and prokinetics, with potential side effects. Ongoing research for new diagnostic and therapeutic tools promises to improve the management and prognosis of these patients.

[Postpartum ovarian vein thrombophlebitis: diagnosis, treatment and follow-up. Retrospective study over 10 years]. / Thrombophlébites pelviennes du post-partum : diagnostic, traitement et suivi. Etude rétrospective sur 10ans.

INTRODUCTION: Postpartum ovarian vein thrombosis (POVT) is a rare but serious postpartum complication that can be life-threatening due to its embolic and septic risks. The clinical and paraclinical diagnosis is difficult because of the non-specific signs and the absence of a gold standard for imaging. There is no consensus in the literature on the treatment and follow-up of these patients. The primary objective was to specify the clinical and paraclinical signs suggestive of POVT in order to improve the diagnostic delay. The secondary objectives were to describe the extent of POVT and the proposed immediate therapeutic management. METHODS: This was a 10-year retrospective study in a type III maternity hospital, from January 2010 to December 2019, where all patients with an imaging-confirmed diagnosis of POVT were included. We analysed the clinical and paraclinical data and the follow-up of the patients. RESULTS: We included 9 patients with a diagnostic confirmation by imaging. The mean time from first symptoms to diagnosis was 3.3 days (±3.5 days), and only 2 patients (22.2 %) had been diagnosed with POVT before imaging. All patients received curative anticoagulation and 77.8 % (n=7) received antibiotic therapy for POVT. Two patients had a complicated form, 1 with a pulmonary embolism and 1 with a urinary tract compression requiring a urinary diversion with a double J catheter. Five patients (55.6 %) had a thrombophilia check-up. CONCLUSION: The diagnosis of POVT is difficult and needs to be evoked in front of a painful symptomatology or a fever in postpartum. It can be made by ultrasound, but the injected CT scan specifying the specific search for a POVT remains the imaging examination of choice in order to confirm the diagnosis and eliminate differential diagnoses. Under curative anticoagulation and broad-spectrum antibiotic therapy, the clinical course is generally very favourable. A consultation with an internist makes it possible to define instructions for a subsequent pregnancy.

[Evaluation of a woman's care program after pre-eclampsia]. / Évaluation d'un parcours de soin chez la femme au décours d'une prééclampsie.

INTRODUCTION: The medical treatment of preeclampsia is well structured in its acute phase but the required follow-up with patients in post-partum is discussed. However, preeclampsia is associated with an increased risk of cardiovascular morbi-mortality in the long term. In order to optimize the post-partum treatment, a care program has been developed for these patients in the city of Nantes, France. This includes a check-up of the cardiovascular risks at a day hospital. Our study presents the first results of this program. METHODS: The study included 134 patients who were diagnosed with preeclampsia between October 2016 and January 2019 in the Nantes area, France, and took part in the program within the year following their childbirth. A descriptive analysis was first carried out and then a multivariate logistic regression model was used to investigate the risk factors for persistent high blood pressure after preeclampsia. RESULTS: The study detected 28 cases of persistent hypertension (20.9%), 34 cases of obesity (25.3%) and 1 case of diabetes. Hypertension was predominantly diastolic, mild and sometimes masked (35.7%). In a third of the cases (32.1%), the hypertension was secondary. High blood pressure was found to be more frequent in older patients (OR: 2.26; 95% CI: 1.25-4.11, p=0.072), patients from sub-Saharan Africa (OR: 11.52; 95% CI: 2.67-49.86, p=0.01) and multiparous patients (OR: 7.82; 95% CI: 1.15-53.21, p=0.035). CONCLUSION: The study confirmed that this care program enables an earlier detection and therefore treatment of the cardiovascular risk factors of these young women.

[An hereditary hemorrhagic telangiectasia of late revealed by a cerebral venous thrombosis: A case report]. / Une télangiectasie hémorragique héréditaire révélée tardivement par une thrombose veineuse cérébrale : à propos d'un cas.

INTRODUCTION: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease characterized by the triad of nose bleeding, telangiectasia and familial heredity. CASE REPORT: We report the case of a patient who had idiopathic venous cerebral thrombosis complicated by a cerebral infarction treated with warfarin. In the context of a psoas hematoma by warfarine overdose and immobilization, the patient had deep vein thrombosis of the left lower limb with pulmonary embolism revealing a pulmonary arteriovenous malformation. After a reexamination, the patient clinical phenotype of HHT was confirmed genetically. The patient was treated with rivaroxaban allowing clinical improvement and partial recanalization of all thrombosis after six months. Thrombotic overisk has already been studied in HHT patients but the use of anticoagulants is at higher risk in these patients. However this patient experienced no adverse event with rivaroxaban. CONCLUSION: This is the first case described of cerebral venous thrombosis treated with rivaroxaban revealing an HHT.

Management of cancer-related thrombosis in the era of direct oral anticoagulants: A comprehensive review of the 2019 ITAC-CME clinical practice guidelines. On behalf of the Groupe Francophone Thrombose et Cancer (GFTC).

Venous thromboembolism (VTE) is a common disease complication in cancer patients and the second cause of death after cancer progression. VTE management and prophylaxis are critical in cancer patients, but effective therapy can be challenging because these patients are at higher risk of VTE recurrence and bleeding under anticoagulant treatment. Numerous published studies report inconsistent implementation of existing evidence-based clinical practice guidelines (CPG), including underutilization of thromboprophylaxis, and wide variability in clinical practice patterns across different countries and various practitioners. This review aims to summarize the 2019 ITAC-CME evidence-based CPGs for treatment and prophylaxis of cancer-related VTE, which include recommendations on the use of direct oral anticoagulants specifically in cancer patients. The guidelines underscore the gravity of developing VTE in cancer and recommend the best approaches for treating and preventing cancer-associated VTE, while minimizing unnecessary or over-treatment. Greater adherence to the 2019 ITAC guidelines could substantially decrease the burden of VTE and improve survival of cancer patients.

[Update on cholesterol crystal embolism]. / État des lieux de la maladie des emboles de cholestérol.

Cholesterol crystal embolism is a systemic pathology associated with diffuse atherosclerosis. Pathophysiology corresponds to tissue necro-inflammation secondary to arteriolar occlusion associated with microembolism from atherosclerotic plaques of large diameter arteries. The clinical presentation is heterogeneous and polymorphic. Multiple organs may be the targets, but preferential damage is skin, kidneys and digestive system. It is a serious pathology, underdiagnosed, with a poor prognosis. The risk factors for developing the disease remain the same risk factors as atheroma. The factors favouring migration of microembolism remain mainly vascular interventional procedures; easy to diagnose, they oppose spontaneous embolic migrations or secondary to the introduction of antithrombotic treatment, whose diagnosis is more difficult and the prognosis more severe. The diagnosis of the disease remains mostly a diagnosis of elimination and often refers to a bundle of clinical, biological, morphological and histologic arguments. The treatment is poorly codified and the subject of few publications. It will favour both symptomatic treatment (and mainly that of pain) and complications (high blood pressure, renal insufficiency). The aetiological support remains less consensual. The treatment of atherosclerotic plaques consists, of course, in the correction of classical cardiovascular risk factors, the introduction of a statin. It will be discussed in the implementation of surgery or angioplasty to exclude potentially responsible atherosclerotic lesions. Eviction of antithrombotic therapy should be considered in terms of the benefit-risk balance, but often in favour of maintaining it. Finally, other treatments may be proposed in a case-by-case basis, such as oral or intravenous corticosteroid therapy, colchicine or LDL aphaeresis.

Giant cell arteritis-related aortitis with positive or negative temporal artery biopsy: a French multicentre study.

Objective: To compare the clinical presentation and outcome of giant cell arteritis (GCA)-related aortitis according to the results of temporal artery biopsy (TAB).Method: Patients with GCA-related aortitis diagnosed between 2000 and 2017, who underwent TAB, were retrospectively included from a French multicentre database. They all met at least three American College of Rheumatology criteria for the diagnosis of GCA. Aortitis was defined by aortic wall thickening > 2 mm on computed tomography scan and/or an aortic aneurysm, associated with an inflammatory syndrome. Patients were divided into two groups [positive and negative TAB (TAB+, TAB-)], which were compared regarding aortic imaging characteristics and aortic events, at aortitis diagnosis and during follow-up.Results: We included 56 patients with TAB+ (70%) and 24 with TAB- (30%). At aortitis diagnosis, patients with TAB- were significantly younger than those with TAB+ (67.7 ± 9 vs 72.3 ± 7 years, p = 0.022). Initial clinical signs of GCA, inflammatory parameters, and glucocorticoid therapy were similar in both groups. Coronary artery disease and/or lower limb peripheral arterial disease was more frequent in TAB- patients (25% vs 5.3%, p = 0.018). Aortic wall thickness and type of aortic involvement were not significantly different between groups. Diffuse arterial involvement from the aortic arch was more frequent in TAB- patients (29.1 vs 8.9%, p = 0.03). There were no differences between the groups regarding overall, aneurism-free, relapse-free, and aortic event-free survival.Conclusion: Among patients with GCA-related aortitis, those with TAB- are characterized by younger age and increased frequency of diffuse arterial involvement from the aortic arch compared to those with TAB+, without significant differences in terms of prognosis.

[Hemolytic disorders and venous thrombosis: An update]. / Maladies hémolytiques et thrombose veineuse : mise au point.

Many factors can contribute to the risk of venous thrombosis observed in hemolytic diseases. Some mechanisms are related to hemolysis by itself, while others seem more specific to each disease. Despite recent advances in the quantification of this risk and in understanding its physiopathology, the association of hemolysis with venous thrombosis is often unknown. The purpose of this general review is to clarify the main pro-thrombotic mechanisms during hemolysis and to synthesize the clinical data currently available. We will focus on the main types of hemolytic pathologies encountered in current practice, namely paroxysmal nocturnal hemoglobinuria, hemoglobinopathies, auto-immune hemolytic anemia and thrombotic microangiopathies.

[Upper-extremity venous thrombosis: A retrospective study about 160 cases]. / Épidémiologie des thromboses veineuses des membres supérieurs : étude rétrospective de 160 thromboses aiguës.

AIM: To describe the clinical features and etiologies of upper limb venous thrombosis (ULVT). METHODS: All patients with a clinically suspected ULVT, were included retrospectively from January to December 2016. Diagnosis of ULVT was based on doppler-ultrasonography. Clinical features, topography and symptomatic pulmonary embolism (PE) were analyzed. The sensitivity (Se), specificity (Sp), positive predictive value (PPV) and negative value (NPV) of clinical symptoms leading to ULVT suspicion were estimated by comparing patients with and without ULVT. RESULTS: Among 488 patients with a suspected ULVT, 160 were diagnosed with ULVT, including, 80 with deep venous thrombosis (DVT) and 80 with superficial venous thrombosis (SVT). Symptomatic PE was found in 2.5 % of cases (n=4). None of the clinical symptoms of ULVT had a sensitivity greater than 40 %. For DVT, presence of superior vena cava syndrome had a 100 % PPV, 71.6 % NPV and 100 % Sp. For SVT, the presence of an cord-like induration had a 85.7 % PPV, 75.3 % NPV and 98.4 % Sp. An endovenous device was present in 87.5 % of DVT and 97.5 % of SVT cases. Malignant hemopathy was found in 43.8 % and 31.3 % of cases of DVT and SVT, respectively. Sepsis and solid neoplasia were present in 25 % and 15 % of cases of ULVT, respectively. Peripherally inserted central catheter or implantable sites were present in 40 % and 17.5 % of DVT patients. No solid neoplasia, hematological malignancy or thrombophilia were diagnosed in patients with ULVT. CONCLUSION: An endovenous device was involved in 92.5 % of cases of ULVT. The prevalence of symptomatic PE was low. Hematological malignancies, sepsis and neoplasia were the most common conditions present in patients with ULVT.

[Late-onset systemic sclerosis: A retrospective study of 27 patients diagnosed after the age of 70]. / Sclérodermie systémique de révélation tardive : étude rétrospective de 27 patients diagnostiqués après l'âge de 70 ans.

BACKGROUND: The aim of this study was to describe special features of patients with systemic sclerosis (SSc) diagnosed after the age of 70. PATIENTS AND METHODS: This is a retrospective study of patients aged above 70 years at the time of diagnosis of SSc and followed at an internal medicine unit between 2000 and 2015. Co-morbidities and clinical characteristics were analyzed, as well as survival at 1, 2 and 3 years. RESULTS: Of 246 patients, 27 (11%) were included (89% women, 96% Caucasians, age 78.3±4.5 years). Synchronous cancer was noted in 3 patients. SSc was mostly limited cutaneous only (24/27), with telangiectasia (63%), gastroesophageal reflux (59%) and digital ulcers (22%), and was associated with anti-centromere antibody (69%). Interstitial lung disease was not frequent (29%). Pulmonary arterial hypertension (PAH) was suspected at diagnosis of SSc in 14 cases (52%), but only 5 patients had undergone heart catheterization, with severe PAH in 3 cases. Survival at 1 and 3 years was 85.2% and 66.7%, and was worse in the case of suspected PAH, at 78.6% and 57.1% respectively. CONCLUSION: Cases of SSc diagnosed after 70 years are mostly limited cutaneous forms. Suspicion of PAH is frequent, and PAH may be the main initial sign of the disease for patients at this age. There may be association with synchronous cancer. Survival is poor.

[New international guidelines for curative treatment and prophylaxis for venous thromboembolism (VTE) in cancer patients and the dedicated smartphone application]. / Nouvelles recommandations internationales pour le traitement curatif et prophylactique de la maladie thromboembolique veineuse chez les patients atteints d'un cancer et application dédiée pour smartphone.

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.

[Qualitative and quantitative evaluation of an internal medicine assistance line dedicated to the diagnosis and treatment of diseases for general practice]. / Évaluation qualitative et quantitative d'un service d'assistance téléphonique de médecine interne dédié à l'aide diagnostique et thérapeutique de pathologies relevant du champ de la médecine générale.

PURPOSE: Clinical reasoning and treatment challenges within the scope of general practice led to the development of an internal medicine assistance line provided by Nantes University Hospital. The primary outcome of this study was to describe callers' profile, their requests and answers provided. METHODS: A prospective, cross-sectional, observational, descriptive study was undertaken. For each call were identified the calling physician, her/his specialty and work setting, the call's object and adequacy, the answer provided, the time needed to connect with the assistance line, the time devoted by the internal medicine physician to provide an answer to the request, and whether the assistance line prevented a visit to the emergency room. Each calling physician was then called back to obtain demographic and professional characteristics, and data relating to the call and to the assistance line. RESULTS: Sixty-three days were analyzed and 276 calls identified. The 237 identified calling physicians were mainly females (54%, n=93), with a mean age of 46 years, graduated from Nantes University (65%, n=86), practicing ambulatory general medicine (69%, n=164) in Loire-Atlantique department area (82%, n=176) for a mean duration of 15 years. Calls were mostly associated with diagnostic challenges (61%, n=166) concerning clinical issues (57%, n=155). A sole telephone advice was the main type of answer provided (56%, n=147) and a visit to the emergency room was prevented for 17% of calls. CONCLUSION: The assistance line activity is adequate with its missions and seems to facilitate patients' healthcare delivery advocating for the development of similar structures in other units. Improvements relating to the information, availability and physicians' training should be considered.

Early symptoms and long-term clinical outcomes of distal limb's cutaneous arterio-venous malformations: a retrospective multicentre study of 19 adult patients.

INTRODUCTION: Cutaneous arterio-venous malformations (AVM) are high-flow vascular malformations made up of a direct link between arteries and veins without intermediary capillary space. 'Distal limb's AVM', which mean involving hands or feet, are rare and their functional prognosis is often poor. Little is known about their early clinical symptoms. The objectives of this study were to identify early clinical symptoms of distal limb's cutaneous AVMs and to determine their long-term clinical outcome. METHODS: A retrospective study was carried out including adult patients who had distal limb's AVM, who were followed up between January 2000 and November 2013 in two regional tertiary care centres. The information was collected from patients' clinical records and completed by a structured telephone questionnaire. RESULTS: Nineteen patients were included in the study: four (21%) with foot AVM and 15 (79%) with hand AVM. The first clinical symptoms were as follows: swelling (47%), pain (47%), one or several venous dilatations (37%) and rarely abnormal skin colour, hyperthermia and pulsating sensation. The median diagnosis delay was 9 years after the onset of first manifestations. Amongst the 17 patients who underwent a treatment, 53% had embolotherapy session(s), 12% surgery and 35% had both. After an average follow-up of 57.6 months, 31% of the 13 patients contacted who were receiving treatment were in complete remission; 31% had partial remission; 15% had relapse after initial improvement and 23% had treatment failure. Overall, 74% of patients had a serious development of the AVM: 37% had digital or hand amputation, and 42% remained symptomatic and/or unstable. CONCLUSION: This study suggests that initial manifestations of distal limb's AVMs are discreet and non-specific, leading to a diagnosis delay of about 10 years, with poor prognosis. Doctors should evoke the diagnosis earlier, when these symptoms are shown: pain and/or swelling, sometimes with a large vein.

Venous thromboembolism related to warm autoimmune hemolytic anemia: a case-control study.

BACKGROUND: The risk of venous thromboembolism (VTE) during warm autoimmune hemolytic anemia (wAIHA) is apparent in several published series. Unlike proximate disorders (autoimmune thrombocytopenia, non-immune hemolytic diseases) little is known about the presentation and risk factors for VTE in this setting. OBJECTIVE: To determine the frequency, presentation and risk factors for VTE associated with wAIHA. METHODS: We performed a single center retrospective study of adult patients (>18years) followed for wAIHA between 2009 and 2013. VTE risk factors were systematically assessed. The characteristics of patients with or without VTE were compared. VTE presentation and precipitating factors were analyzed. The Padua VTE risk score was calculated in each case. RESULTS: Forty patients were included. wAIHA was idiopathic in 24 patients (60%). Twelve patients (30%) had Evans syndrome. Mean lowest hemoglobin level was 6.6g/dl [3.7-11.5]. Eight patients (20%) presented VTE after the appearance of wAIHA, at a mean age of 52.5years. All patients had pulmonary embolus, associated with a deep venous thrombosis in 4 cases. At the time of VTE 7/8 patients had frank hemolysis (median hemoglobin level: 7g/dL) and 6/8 were outpatients with a low Padua VTE risk score. The frequency of usual VTE risk factor was similar in cases and controls. By contrast, lowest hemoglobin level was significantly lower in patients that experienced VTE (5.3 vs 7.2g/dL, p=0.016). During the first episode of wAIHA, patients with concurrent VTE had a more pronounced anemia (5.3 vs 7.4g/dL, p=0.026). At the time of VTE, anemia was more severe when no other precipitating factor was present (6 vs 8.9g.dL, p=0.04). CONCLUSION: In our cohort, 20% of patients with wAIHA presented VTE. The vast majority of VTE occurred during severe hemolytic flares and were not attributable to usual VTE risk factors. VTE prophylaxis is advisable in any patient admitted for wAIHA, irrespective of Padua VTE risk score. Prophylaxis also seems reasonable for outpatients with marked hemolysis.

Challenges of controlling a large outbreak of OXA-48 carbapenemase-producing Klebsiella pneumoniae in a French university hospital.

A large outbreak of OXA-48 carbapenemase-producing Klebsiella pneumoniae at Nantes University Hospital was investigated. The index case had no history of travel or hospitalization abroad and had been hospitalized in the internal medicine department for more than one month when the epidemic strain was isolated from a urine sample in June 2013. Seventy-two secondary cases were detected by weekly screening for gastrointestinal colonization during the two phases of the outbreak from June to October 2013 (33 cases) and from November 2013 to August 2014 (39 cases). Spread of the epidemic strain was attributed to the proximity of, and staff movement between, the infectious diseases (32 cases) and the internal medicine (26 cases) departments; 14 secondary cases were also observed in the renal transplant department following the transfer of an exposed patient from the infectious diseases department. Most of the patients (90%) were colonized and no death was linked to the epidemic strain. More than 3000 contact patients were reviewed and 6000 rectal swabs were performed. Initial control measures failed to control the outbreak owing to the late detection of the index case. The late implementation of three successive cohort units, the large number of transfers between wards, and the frequent readmission of cases contributed to the incomplete success of control measures.

Diagnostic and medical strategy for renovascular hypertension: report from a monocentric pediatric cohort.

UNLABELLED: Renovascular hypertension accounts for 5-10 % of hypertension cases in children; there is currently no consensus on treatment. Here, we report on our clinical experience with this disease and outline the different pathways in which to investigate it. We report retrospectively on ten children diagnosed with renovascular hypertension at the University Hospital of Nantes from 2001 to 2012. The main findings were obtained by fortuitous screening of children aged 2 months to 14 years old with neurofibromatosis (n = 2) and fibromuscular dysplasia (n = 8). The hypertension was always severe yet asymptomatic. Lesions were complicated in nine out of ten cases and included bilateral, multiple, mid-aortic syndrome and aneurysm. Doppler ultrasound associated with computed tomography allowed for a precise diagnosis in seven out of ten cases. Where ambiguities persisted, they were highlighted by arteriography, the gold standard investigation. Medical treatment was insufficient, leading to invasive procedures in nine out of ten children: 2 nephrectomies, 2 autotransplantations, and 21 repetitive percutaneous transluminal angioplasties. After invasive procedures, blood pressure control improved in four cases and was resolved in three. CONCLUSION: Arteriography remains to be the gold standard technique for renovascular hypertension in children and can be combined with angioplasty when medical treatment is rendered obsolete. The role of computed tomography is controversial. Despite the heterogeneity of the children studied, we present a general medical and therapeutic management pathway for the treatment of this disease.

[Skin manifestations of monoclonal gammopathies]. / Manifestations cutanées associées aux gammapathies monoclonales.

Whatever their aetiology, monoclonal gammopathies can be associated to several clinical features. Mechanisms are various and sometimes unknown. Skin is frequently involved and may represent a challenging diagnosis. Indeed, skin manifestations are either the presenting features and isolated, or at the background of a systemic syndrome. Our objective was to review the various skin manifestations that have been associated with monoclonal gammopathies.

[Localized purpura revealing vascular prosthetic graft infection]. / Purpura localisé révélateur d'une infection tardive de prothèse vasculaire.

Prosthetic graft infection after vascular reconstruction is a rare but serious complication. We report a case of infection occurring late after implantation of an iliofemoral prosthetic vascular graft. The Staphylococcus aureus infection was revealed by vascular purpura localized on the right leg 7 years after implantation of a vascular prosthesis. This case illustrates an uncommonly late clinical manifestation presenting as an acute infection 7 years after the primary operation. In this situation, the presentation differs from early infection, which generally occurs within the first four postoperative months. Diagnosis and treatment remain a difficult challenge because prosthetic graft infection is a potentially life-threatening complication. Morbidity and mortality rates are high. Here we detail specific aspects of the clinical and radiological presentation.
