[Systemic Rosai-Dorfman-Destombes disease associated with a myelodysplastic syndrome. Efficacy of hematologic treatment]. / Maladie de Rosai-Dorfman-Destombes (RDD) multifocale réfractaire associée à un syndrome myélodysplasique. Efficacité du traitement hématologique.

INTRODUCTION: We report an original observation of multifocal refractory Destombes-Rosai-Dorfman disease associated with a myelodysplastic syndrome. The treatment of myelodysplasia allowed a good and prolonged response of both pathologies. CASE REPORT: A 35-year-old patient was investigated for bilateral exophthalmia, histologically related to Destombes-Rosai-Dorfman disease. The extension workup showed sinus, kidney and lymph node involvement. It was treated unsuccessfully with corticosteroids, colchicine, methotrexate, infliximab, cladribine and tociluzimab. The secondary appearance of myelodysplasia (AREB IPSS score intermediate-2) led to induction treatment with aracytin and idarubicin, and maintenance with azacytidine for 2 years. With 5 years of follow-up, the patient is in remission both of the myelodysplastic syndrome and Destombes-Rosai-Dorfman disease. CONCLUSION: Our observation discusses the interest of the treatment of myelodysplastic syndrome for the management of associated extra-hematological manifestations.

[Diagnostic journey of type 1 Gaucher Disease patients: A survey including internists and hematologists]. / Parcours diagnostique des patients atteints de maladie de Gaucher de type 1 : enquête auprès de médecins internistes et hématologues.

INTRODUCTION: Gaucher disease (GD) is a rare genetic lysosomal storage disorder caused by a beta-glucocerebrosidase deficiency and responsible for a lysosomal storage disorder. GD is characterized by haematological, visceral and bone involvements. The aim of this study was to describe the diagnostic journey of type 1 GD patients as well as the role of the internist. METHODS: A retrospective multicentric study involving type 1 GD patients has been conducted in 16 centers, between 2009 and 2011. RESULTS: Fifty-five type 1 GD patients were included, under the care of an internist or an haematologist. They were originally hospitalized in 8 different specialized units. Diagnosis was established by bone-marrow aspiration in 22 patients (40%), by enzymatic assay of glucocerebrosidase activity in 15 patients (27%), and by bone-marrow biopsy in 9 patients (16%). The use of enzymatic assay became more frequent after 1990. The delay between first hospitalization due to GD symptoms and definitive diagnosis was less than one year for 38 patients. Patients with suspected GD were mainly referred to an internist physician. CONCLUSION: GD seems to be better recognized and quickly diagnosed since 1990 in spite of the multiplicity of journeys. The role of the internist seems important.

[Chronic histiocytic intervillositis: Diagnosis and management]. / Intervillites chroniques histiocytaires : bilan et prise en charge.

Chronic intervillositis is a rare condition, which is associated with severe obstetrical outcome and high recurrence rate. Obstetrical adverse events are intrauterine growth restriction, recurrent early miscarriages, intrauterine deaths and prematurity by placental insufficiency. The determination of the extension and the intensity of the chronic intervillositis are not currently standardized. High rates of recurrence have been described, but actually there is no reliable predictive biomarker. No treatment is currently validated, but the use of immunomodulatory drugs could be justified by the possible autoimmune or allo-immune origin. The treatment should be particularly discussed in patients with recurrent and severe obstetrical adverse events and in the presence of severe and massive histological lesions.

Schnitzler syndrome: validation and applicability of diagnostic criteria in real-life patients.

BACKGROUND: Schnitzler syndrome is characterized by an urticarial rash, a monoclonal gammopathy, and clinical, histological, and biological signs of neutrophil-mediated inflammation. The aim of this study was to assess the applicability and validity of the existing diagnostic criteria in real-life patients. METHODS: This multicentric study was conducted between 2009 and 2014 in 14 hospitals in which patients with Schnitzler syndrome or controls with related disorders were followed up. We compared the sensitivities and specificities and calculated the positive and negative predictive values of the Lipsker and of the Strasbourg criteria for the patients with Schnitzler syndrome and for the controls. We included 42 patients with Schnitzler syndrome, 12 with adult-onset Still's disease, 7 with cryopyrin-associated periodic disease, 9 with Waldenström disease, and 10 with chronic spontaneous urticaria. RESULTS: All patients with Schnitzler syndrome met the Lipsker criteria. According to the Strasbourg criteria, 34 patients had definite Schnitzler syndrome, five had probable Schnitzler syndrome, and three did not meet the criteria. One control met the Lipsker criteria and had probable Schnitzler syndrome according to the Strasbourg criteria. Sensitivity and specificity of the Lipsker criteria were 100% and 97%, respectively. For the Strasbourg criteria, sensitivity for definite and probable diagnosis was 81% and 93%, respectively, with a corresponding specificity of 100% and 97%. CONCLUSION: Diagnostic criteria currently in use to diagnose Schnitzler syndrome are reliable. More investigations must be done to attest their efficiency in patients with recent-onset manifestations.

Comparison of idiopathic (isolated) aortitis and giant cell arteritis-related aortitis. A French retrospective multicenter study of 117 patients.

OBJECTIVES: The aim of the study was to compare clinical/imaging findings and outcome in patients with idiopathic (isolated aortitis, IA) and with giant cell arteritis (GCA)-related aortitis. METHODS: Patients from 11 French internal medicine departments were retrospectively included. Aortitis was defined by aortic wall thickening >2mm and/or an aortic aneurysm on CT-scan, associated to inflammatory syndrome. Patients with GCA had at least 3 ACR criteria. Aortic events (aneurysm, dissection, aortic surgeries) were reported, and free of aortic events-survival were compared. RESULTS: Among 191 patients with non-infectious aortitis, 73 with GCA and 44 with IA were included. Patients with IA were younger (65 vs 70 years, p=0.003) and comprised more past/current smokers (43 vs 15%, p=0.0007). Aortic aneurisms were more frequent (38% vs 20%, p=0.03), and aortic wall thickening was more pronounced in IA. During follow-up (median=34 months), subsequent development of aortic aneurysm was significantly lower in GCA when compared to IA (p=0.009). GCA patients required significantly less aortic surgery during follow-up than IA patients (p=0.02). Mean age, sex ratio, inflammatory parameters, and free of aortic aneurism survival were equivalent in patients with IA ≥ 60 years when compared to patients with GCA-related aortitis. CONCLUSIONS: IA is more severe than aortitis related to GCA, with higher proportions of aortic aneurism at diagnosis and during follow-up. IA is a heterogeneous disease and its prognosis is worse in younger patients <60 years. Most patients with IA ≥ 60 years share many features with GCA-related aortitis.

[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.

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.

[Antisynthetase syndrome with pulmonary hypertension: 4 original observations]. / Syndrome des antisynthétases compliqué d'une hypertension pulmonaire : 4 observations originales.

INTRODUCTION: Pulmonary hypertension (PH) may occur in patients with antisynthetase syndrome (ASS) but this association is poorly studied. In this article, we report 4 new cases of PH associated with ASS, and we discuss PH mechanisms in this specific disease. CASES: Four patients (3 females, 1 male) with confirmed ASS associated with anti-Jo1 (n=3), anti-PL7 (n=1), and anti-Ro52 (n=3) antibodies were analyzed. They presented with subacute dyspnea in average ten years after they were first diagnosed as ASS. Diagnosis of pre-capillary PH was made (mean of mPAP: 34mmHg): PAH (n=1), group 3 PH (n=2) and PH associated to hyperthyroidism (n=1). Among three patients who received specific PAH therapy, two had significant improvement in both clinical and hemodynamic parameters. CONCLUSION: During ASS, PH may occur in 5 to 10 % of cases, caused by various mechanisms. Unexplained dyspnea may be due to PH among ASS patients.

[In vitro fertilization and systemic lupus erythematosus or antiphospholipid syndrome: An update]. / Fécondation in vitro au cours du lupus érythémateux systémique ou du syndrome des antiphospholipides : mise au point.

Fertility is not impaired in systemic lupus erythematosus or antiphospholipid syndrome, but, similarly to the general population, these patients may undergo in vitro fertilization. This type of treatment increases the risk of lupus flare, thrombosis, and ovarian hyperstimulation syndrome. This review will focus on in vitro fertilization in systemic lupus erythematosus or antiphospholipid syndrome. Literature data are relatively scant with only 3 reported studies. The first one included 17 patients and 63 cycles of induction ovulation/in vitro fertilization leading to 25 % of lupus flare, no thrombosis, and 3 % of ovarian hyperstimulation syndrome. The second study included 10 patients and 40 cycles of in vitro fertilization showing 31 % of lupus flare, no thrombosis and no ovarian hyperstimulation syndrome. The last one included 34 patients and 83 procedures of in vitro fertilization leading to 8 % of flares, 5 % of thrombosis and no ovarian hyperstimulation syndrome. Interestingly, in this last study, half of the complications were explained by poor adherence to treatment. These data are reassuring but it is important to remember that in vitro fertilization should be scheduled and carefully supervised in the same way as the high-risk pregnancies occurring in these patients.

[Macrovesicular hepatic steatosis revealing pregnancy hemophagocytic lymphohistiocytosis]. / Stéatose hépatique macrovésiculaire majeure révélant un syndrome d'activation lymphohistiocytaire postgravidique.

INTRODUCTION: We report a case of post-partum hemophagocytic lymphohistiocytosis with marked macrovesicular hepatic steatosis. CASE REPORT: A 39-year-old woman was admitted for hemophagocytic lymphohistiocytosis with a serum ferritin level of 103,380 µg/L. Thoracic abdominal and pelvic CT-scan showed hepatomegaly with marked steatosis. Liver biopsy confirmed macrovesicular steatosis. The diagnosis was a primary hemophagocytic lymphohistiocytosis. After treatment failure including corticosteroids, intravenous immunoglobulin, tetracycline, acyclovir, antituberculosis drugs, and anti-IL1R therapy, clinical improvement was obtained with intravenous cyclosporine. At 4-year follow-up, the patient remained asymptomatic. CONCLUSION: Several aspects of this report of primary hemophagocytic lymphohistiocytosis are remarkable and include the association with post-partum, the severe radiologic and histologic macrovesicular steatosis, and the dramatic efficacy of cyclosporine.

[Syphilis in Nantes tertiary care hospital between 2000 and 2010: a case series of 36 hospitalized patients]. / La syphilis au CHU de Nantes entre 2000 et 2010 : à propos de 36 patients hospitalisés.

PURPOSE: Syphilis infection increase has been observed since the early 2000s. The medical records of patients hospitalized for syphilis at the tertiary care hospital of Nantes between 2000 and 2010 were retrospectively reviewed. METHODS: Cases were selected on the basis of serological database of the laboratory of bacteriology and extraction from the PMIS. Syphilis cases were defined by both positive TPHA and VDRL tests. RESULTS: The number of positive serology testing was increased eightfold within ten years. Among the 36 patients with syphilis hospitalized cases, 97% were male, aged 17 to 75 years. Eighteen were HIV-infected patients. Among them, 94% were homosexuals and 67% had a history of sexually transmitted infections. The mean time between symptoms and diagnosis was significantly higher in non HIV-infected patients. Clinical forms of syphilis were cutaneomucous secondary syphilis with frequent systemic symptoms for 33%, neurosyphilis, including frequent uveitis for 50%, and gummatous tertiary syphilis involving bones for one patient. Secondary syphilis cases were treated with one to three doses of benzathine penicillin G. Late syphilis and cases of neurosyphilis were treated with penicillin G or ceftriaxone. Neurosensory sequelae accounted for 39% neurosyphilis cases. CONCLUSION: This study highlights the incidence increase of syphilis cases in France, frequent poor prognosis of neurosyphilis cases, and diagnosis difficulties, particularly in non HIV-infected patients. This emphasizes the broader use of syphilis serology for compatible medical situations.

[Schnitzler's syndrome]. / Le syndrome de Schnitzler.

Schnitzler syndrome (SS) is a rare clinical entity, which belongs to the spectrum of monoclonal gammapathy-associated systemic disorders. Its pathophysiology remains elusive, even if it is tempting to consider it as a late onset and probably acquired auto-inflammatory syndrome. SS mainly occurs in the fifth and sixth decade, and present with an urticariform rash with periodic fever and/or osteoarticular pain. Systemic inflammation and monoclonal gammapathy (overwhelmingly IgM kappa) are constant features. SS is a chronic disease, which can severely impair quality of life of the affected individuals. Many drugs have been used and proved disappointing. In the last few years, accumulating reports provided evidence for the dramatic efficacy of anakinra, which has revolutionized the management of most severe cases. The main long-term threat to these patients is to develop a lymphoproliferative disorder (mainly Waldenström's macroglobulinemia). The mechanisms underlying the different facets of the disease remain to be elucidated.

Multidimensional analysis of clinical symptoms in patients with Fabry's disease.

AIM: Fabry's disease is an X-linked inherited lysosomal storage disorder caused by the deficient activity of alpha-galactosidase A. The interrelationships between clinical symptoms in Fabry patients have not yet been fully established. Using cluster and multivariate analysis, the aim of the study was to determine the relationships among clinical symptoms and organ involvement, and predictive clinical symptoms for disease severity. METHODS: Clinical data obtained from 108 French Fabry patients were retrospectively collected and analysed using multiple correspondence analysis and hierachical ascendant classification. Multivariate analysis was also performed to determine among clinical symptoms predictors for cardiac disease (HRT), renal involvement (KDN) and brain complication (STR). RESULTS: The cohort comprised 41 male patients (aged 28.9 ± 11.6 years) and 67 female patients (aged 40.4 ± 15.5 years). Three main clusters of clinical symptoms could be delineated, characterising disease progression: the first cluster grouped digestive disorders (found in 30% of the patients) and exercise intolerance (32%), the second, cluster dyshidrosis (47%), acroparesthesia (67%), angiokeratoma (44%) and cornea verticillata (54%), the third, cluster grouped KDN (30%), HRT (39%) and STR (25%) and hearing loss (44%). In univariate analysis, the patient age predicted HRT and KDN, dyshidrosis predicted HRT and STR, angiokeratoma predicted KDN and cornea verticilla and hearing loss predicted KDN, HRT and STR. In multivariate analysis, hearing loss and age were independent predictors of organ complication. CONCLUSION: Among the various interrelated clinical symptoms occurring in Fabry disease, patients with dyshidrosis and particularly hearing disorders appear to be at higher risk of organ complications.

[Idiopathic granulomatous mastitis]. / La mastite granulomateuse idiopathique.

Idiopathic granulomatous mastitis (IGM) is a rare localized granulomatosis of unknown aetiology that usually affects women of childbearing age. It often mimics breast carcinoma or abscess. Histopathologic evaluation and elimination of the others aetiologies of granuloma play a crucial role in the diagnosis. Its etiopathogeny remains poorly understood, but Corynebacteria might be involved. The disease course is usually protracted, with a significant impact on quality of life. The management of IGM remains controversial, but corticosteroids are usually the first-line treatment.

[Acquired hemophilia A. A monocentric retrospective study of 39 patients]. / Hémophilie A acquise. Étude d'une série rétrospective monocentrique de 39 patients.

PURPOSE: Acquired haemophilia A (AHA) is a rare bleeding disorder, due to the presence of an inhibitor directed against factor VIII (FVIII). About 50% of the AHA are idiopathic, while the remaining 50% are related to an underlying disorder or condition (autoimmune diseases, malignancies, postpartum, etc.). PATIENTS AND METHODS: We report on a monocentric retrospective cohort of 39 patients with AHA. Data were collected and compared to recent published data. RESULTS: Thirty-nine patients were admitted for AHA between 1993 et 2011. Mean age at diagnosis was 71.3 years, and we noted a marked male predominance. Although the majority of patients presented a bleeding event at diagnosis (94.9%), the hemorrhagic mortality was low (2.6%). On the contrary, immunosuppressive morbidity and mortality were high in this elderly population. There was a clear correlation between initial FVIII inhibitor titer and complete remission delay. We did not identify prognostic factor for global survival. CONCLUSION: AHA is a rare but potentially fatal disorder. Rapidity of diagnosis and treatment initiation is crucial. Morbidity and mortality, particularly of infectious cause, due to immunosuppressive treatment, should lead to consider other available therapeutical options.

Fabry disease 'The New Great Imposter': results of the French Observatoire in Internal Medicine Departments (FIMeD).

Fabry disease (FD) is an X-linked lysosomal storage disorder due to α-galactosidase A deficiency. It is associated with a broad range of clinical symptoms, resulting in frequent misdiagnosis and diagnostic delay, which may impact on patient outcomes. This retrospective observational study of 58 FD patients referred to 10 internal medicine departments in France aimed to review differential diagnoses received prior to diagnosis and examines diagnostic delay. The average age at the time of diagnosis was 27.6 years (range: 10-60) and 42.2 years (range: 9-77) among the 23 males and 35 females analyzed, respectively. Most common symptoms that led to FD diagnosis were family history of FD (12 males and 27 females), followed by pain in extremities (10 males and 5 females), and angiokeratoma (8 males and 4 females). Eighteen patients had received alternative diagnoses prior to FD diagnosis, including a female patient with four previous diagnoses. Four case reports are presented, which illustrate the diagnostic 'odyssey' and delayed diagnosis often experienced by patients. Clinicians should consider a diagnosis of FD when presented with a wide range of symptoms, thus helping to shorten the diagnostic delay and facilitating early therapy with enzyme replacement therapy to improve patient outcomes.

[Sweet's syndrome as the presenting manifestation of relapsing polychondritis]. / Syndrome de Sweet révélant une polychondrite atrophiante.

Relapsing polychondritis (RP) is a rare disorder characterized by recurrent inflammatory episodes involving various cartilages. The clinical course of RP is variable, and dermatologic manifestations are uncommon. We report a 73-year-old patient who presented with a neutrophilic dermatosis (Sweet's syndrome) as the initial manifestation of RP. There was no evidence for a myelodysplastic syndrome, as it has been previously reported with RP, but the patient was followed-up for an indolent and untreated chronic lymphocytic leukaemia. Complete remission was obtained with oral corticosteroids. This report highlights the clinical spectrum of the RP.
