Introduction: The 2017 reform of the third cycle of medical studies (R3C) was accompanied by modifications in the formats and number of specialty diplomas. The aim of this study was to investigate the evolution of the choice of the internal medicine and clinical immunology specialty before and after 2017., Methods: We used the median ranking and its evolution, as well as incoming and outgoing remorse rights, as markers of attractiveness. Data on the number of position offered, rankings and affectation were collected from decrees published in the French "Journal Officiel" each year. A survey conducted by the "Amicale des Jeunes Internistes" investigated the reasons for the outgoing or incoming rights to remorse., Results: Before 2017, internal medicine was accessible to 52% of students on average, with a median rank of 1118 [339-2640]. From 2017 onwards, the internal medicine specialty was accessible to an average of 76.6% of students, with a median rank of 2772 [1039-5155]. The balance of incoming and outgoing remorse rights was -4.7% before 2017 and varied between -4.1 and -12.4% from 2017., Conclusion: Since 2017, the median and cut-off ranks of students choosing internal medicine specialty have increased, and balance of incoming and outgoing remorse rights was increasingly negative. A reflection on the attractiveness of the internal medicine specialty is undertaken by the National College of Internal Medicine Teachers in order to make the richness of the specialty and its different modes of practice known to future residents., (Copyright © 2024 Société Nationale Française de Médecine Interne (SNFMI).

Internal medicine is a medical specialty that is often poorly understood by the general public and sometimes misidentified. In an era of increasing subspecialization and high technicality, it is characterized by a comprehensive approach centered on clinical evaluation. Unlike what is observed in most developed countries, where systemic autoimmune diseases are managed by organ specialists based on their mode of presentation, French internists are at the forefront for diagnosing and managing these diseases. Their multidisciplinary training gives them legitimacy to justify this role. Internists also play a crucial role in the management of patients requiring unplanned hospitalizations downstream from emergency departments and in connection with primary care. Internists primarily practice in a hospital setting, with a specific position in the French healthcare system aligned with the training frameworks of all medical specialties. To better define internal medicine, its role in care activities, as well as in education and research, internists organized a General Assembly of internal medicine that took place on September 28, 2023, in Paris. Structured around think tanks focusing on care, education, and research activities, the general assembly aimed to improve visibility on internal medicine and internists. This article recounts the discussions that animated this meeting and highlights the main ideas that emerged. These general assemblies constitute a foundational step and will be followed by a Consultation Conference in order to better identify and promote internal medicine and internists, regardless of their types and places of practice., (Copyright © 2024 The Author(s).

Sarcoidosis is one of the leading causes of inflammatory eye disease. All ocular structures can be affected, but uveitis is the main manifestation responsible for vision loss in ocular sarcoidosis. Typical sarcoid anterior uveitis presents with mutton-fat keratic precipitates, iris nodules, and posterior synechiae. Posterior involvement includes vitritis, vasculitis, and choroidal lesions. Cystoid macular edema is the most important and sight-threatening consequence of sarcoid uveitis. Patients with clinically isolated uveitis at diagnosis rarely develop other organ involvement. Even though, ocular sarcoidosis can have a severe impact on visual prognosis, early diagnosis and a wider range of available therapies (including intravitreal implants) have lessened the functional impact of the disease, particularly in the last decade. Corticosteroids are the cornerstone of treatment for sarcoidosis, but up to 30% of patients achieve remission with requiring high-dose systemic steroids. In these cases, the use of steroid-sparing immunosuppressive therapy (such as methotrexate) is unavoidable. Among these immunosuppressive treatments, anti TNF-α drugs have been a revolution in the management of non-infectious uveitis., (Copyright © 2022 Société Nationale Française de Médecine Interne (SNFMI).

Acute Parvovirus B19 (PVB19) infection is responsible for erythema infectiosum in children and non-specific polyarthralgias in immunocompetent adults associated with skin lesions and rarer manifestations (hepatic, neurological, cardiac or nephrological). In immunocompromised patients, cytopenias are more frequent and in some cases, viremia persists and is responsible for PVB19 chronic infection. PVB19 is responsible for pure red cell aplasia during chronic hemolytic diseases. Acute PVB19 infection is a differential diagnosis of some autoimmune diseases and has been suspected to be a trigger for some autoimmune diseases because of its ability to promote the emergence of autoimmune markers. Mechanisms of molecular mimicry, induction of apoptosis and activation of enzymes have been demonstrated, explaining in part the production of autoantibodies during infection. However, the demonstration of a causal relationship in the triggering of autoimmune disease remains to be done. This review provides a synthesis of the PVB19 infection clinical data in adults with a particular focus on these links with autoimmunity., (Copyright © 2022 Société Nationale Française de Médecine Interne (SNFMI).

Sarcoidosis can develop into a chronic disease in about 30% of cases. When general treatment is indicated, corticosteroids are the first-line treatment. More than one third of patients treated with corticosteroids receive a steroid-sparing agent. Although methotrexate is the most commonly used sparing agent, synthetic antimalarials have been used for more than fifty years on the basis of small, randomised, therapeutic trials. Despite this low level of evidence, chloroquine or more often hydroxychloroquine are used in daily practice, particularly to treat skin, bone and joint sarcoidosis, as well as hypercalcemia and certain types of uveitis. This review summarises the state of knowledge on steroid-sparing therapy in sarcoidosis, particularly in its extra-pulmonary form. These data support the need for good quality therapeutic trials to validate the use of hydroxychloroquine in this specific indication., (Copyright © 2022 Société Nationale Française de Médecine Interne (SNFMI).

Systemic diseases, which are in France mainly monitored in internal medicine, affect multiple organs or tissues. While cutaneous or articular manifestations are the most common, neurological involvement is often associated with severity. Diagnosis of peripheral (e.g, neuropathies) or central (e.g, myelitis) nervous disorders is quite easy through clinical examination and dedicated complementary tests. However, neuropsychological manifestations that affect cognition, including memory, attention, executive functions or reasoning, are difficult to diagnose, sometimes trivialized by practitioners. Their causes are often numerous and interrelated. Nevertheless, these cognitive manifestations are closely related to patients' quality of life, affecting their social life, family dynamics and professional integration but also the treatment adherence. The purpose of this review, focused on the example of systemic lupus erythematosus, is to raise awareness of cognitive dysfunction in systemic diseases including their management from diagnosis to treatments. The final aim is to go further into setting up research groups and care programs for patients with cognitive impairment followed in internal medicine., (Copyright © 2021 Société Nationale Française de Médecine Interne (SNFMI).

Introduction: Spontaneous adrenal hemorrhages (AH) are a rare condition with no consensus about their management., Methods: Patients were identified using the Medicalization of the Information System Program database, imaging software and a call for observations to internists, intensivists and obsetricians working at our institution. Adult patients whose medical records were complete and whose diagnosis was confirmed by medical imaging were included., Results: From 2000 to 2007, 20 patients were identified, including 15 were women. The clinical onset of AH was non-specific. In five cases, AH occurred during pregnancy; four of them were unilateral and right sided. The etiology of the other fifteen (bilateral adrenal hemorrhage in 11) were as follows: antiphospholipid syndrome (n=8), heparin-induced thrombocytopenia (n=4), essential thrombocythemia (n=3), spontaneous AH due to oral anticoagulants (n=1), complication of a surgical act (n=3), and sepsis (n=3). In seven cases, two causes were concomitant. The diagnosis of AH was often confirmed by abdominal CT. An anticoagulant treatment was initiated in 16 cases. Ten of the eleven patients presenting with bilateral adrenal hematomas were treated using a long-term substitute opotherapy. One patient died because of a catastrophic antiphospholipid syndrome., Conclusion: The clinical onset of HS is heterogeneous and non-specific. The confirmatory diagnosis is often based on abdominal CT. The search for an underlying acquired thrombophilia is essential and we found in this study etiological data comparable to the main series in the literature. Adrenal insufficiency is most of the time definitive in cases of bilateral involvement., (Copyright © 2021 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier Masson SAS.

Introduction: Ocular tuberculosis (TB) diagnosisremains difficult and quantiferon (QFT) contribution needs still yet to be specified, despite its generalization in France. The purpose of this observational study is to assess in which ocular inflammation (OI) presentation QFT is prescribed and to evaluate the added value of new QuantiFERON®-TB Gold Plus (QFT-Plus) test for diagnosis ocular TB diagnosis., Patients and Methods: Monocentric, observational study, carried out in an ophthalmology department over a period of 5 months. Inclusion criteria were defined as an existence of an OI for which a QFT-Plus test was part of the etiological investigations. Of the 316 consecutive files, 72 were excluded (indeterminate test, prescription before anti-TNFα or immunosuppressant initiation, missing data, wrong indication) and 244 were selected and divided into two groups: group one (anterior uveitis/episcleritis, n=129) and group two (intermediate/posterior uveitis/optic neuritis/ocular myositis, n=115). All positive QFT patients underwent an etiological investigation including thoracic imaging., Results: Forty-five patients, aged 52±12 years, had positive QFT (18.5%), including 18 patients for group 1 and 27 for group 2. Living in TB-endemic area, TB exposure and chest imaging abnormalities were identified in 70%, 27% and 22% of cases, respectively. OI was chronic in 36% of cases (group one, 4/18; group two, 12/27). None of the 18 patients, in group 1, received anti-tuberculosis treatment (ATT) or experienced a relapse during one-year follow-up. Four QFT+ patients, from group 2 (15%) had another associated disease explaining their uveitis. Among the 23 other patients without identified etiology, 13 had at least one relevant ophthalmological signs predictive of TB uveitis (posterior synechiae, retinal vasculitis and/or choroidal granuloma) (59%). Eleven patients received a 6-month ATT trial. Radiological abnormalities and granulomas at angiography were significantly more frequent among treated patients (p=0.03 and 0.001, respectively). A full OI recovery was observed for 8 patients (73%), considered ex-post as ocular TB. Nine patients in group 2 received rifampicin/isoniazid dual therapy for 3 months, but no conclusion could be drawn as to the benefit of such prescription on OI. QFT rate comparison, according to CD4 stimulation by ESAT-6/CFP-10 peptides or by CD4/CD8 co-stimulation, was comparable and found only 4 cases of discrepancy (1.6%). None of these 4 cases had ocular TB diagnosis., Conclusion: Positive QFT frequency among patients consulting for posterior OI remains high. In this study, radiological abnormalities and granulomas at angiography seemed to be more closely related to clinician decision for starting ATT trial in QFT+ patients, which was effective in 73% of cases. QFT-Plus does not seem more relevant than QFT-TB in exploring an OI. Prospective studies are necessary to codify QFT management in the etiological assessment of OI and clearly define ATT trial indications as well as their modalities., (Copyright © 2020 Société Nationale Française de Médecine Interne (SNFMI).

Adult-onset Still's disease (AOSD), first described in 1971 by Bywaters, is a rare systemic auto-inflammatory disorder of unknown etiology, characterized by a symptomatic triad associating prolonged fever, polyarthritis and rash. The management of this disease has significantly improved since its first description, and, although the overall prognosis of the AOSD is good, with a low attributable mortality, below 3% (but up to 18% depending on the series), some rare complications are still possible, can be life-threatening and change the prognosis of the disease. A literature search was performed to review AOSD's complications: reactive hemophagocytic lymphohystiocytosis, coagulation disorders, fulminant hepatitis, cardiovascular (pericarditis, myocarditis, HTAP) or pulmonary complications, neurologic, renal complications, and AA amyloidosis. For most of AOSD-related complications, corticosteroids remain the first-line treatment, in association with supportive care measures in case of severe complications. In case of inadequate response, multidisciplinary care with concil from a referral center is advised, and IL-1 or IL-6 blockers, but also ciclosporine, are the molecule to use in second intention., (Copyright © 2019 Société Nationale Française de Médecine Interne (SNFMI).

In the past ten years, the better understanding of the pathophysiological mechanisms underlying inflammatory and autoimmune diseases has led to the emergence of many targeted therapies. Among them, the Janus kinase inhibitors are acting upstream in the inflammatory cascade of several key cytokines in disorders such as rheumatoid arthritis, ulcerative colitis or psoriasis. At the moment, these three diseases represent the only indications validated by the FDA and the EMA of the use of JAK inhibitors apart from hematology. Preclinical data and therapeutic trials indicate their efficacy in other autoimmune or inflammatory conditions, such as lupus, dermatomyositis, ankylosing spondylitis, sarcoidosis and giant cell arteritis. This review provides a summary of current use and advancement of knowledge in the use of JAK inhibitors in pathologies faced by internists., (Copyright © 2019. Published by Elsevier Masson SAS.)

Sarcoidosis is one of the leading causes of inflammatory eye disease. Any part of the eye and its adnexal tissues can be involved. Uveitis and optic neuropathy are the main manifestations, which the internists face. This review reports the state of knowledge for these two ocular involvements and proposes an assessment-algorithm for sarcoidosis in patients with suspected sarcoid uveitis. Two groups of patients with sarcoid uveitis can be distinguished: one young and multiethnic group in which ophthalmological findings are various and another group of elderly Caucasian women with mostly chronic posterior uveitis. Clinically isolated uveitis revealing sarcoidosis remains a strictly ocular condition in a large majority of cases. Although it could be a serious condition involving functional prognosis, an early recognition in addition to a growing therapeutic arsenal including intravitreal implant seems to have improved visual prognosis of the disease in the last years. Systemic corticosteroids are indicated when uveitis does not respond to topical corticosteroids or when there is bilateral posterior involvement, especially macular edema and occlusive vasculitis. In up to 25% of cases that require an unacceptable dosage of corticosteroids to maintain remission, additional immunosuppression is used, including methotrexate, azathioprine, and mycophenolate mofetil. Regarding systemic sarcoidosis, infliximab and adalimumab have been successfully used for the treatment of refractory or sight-threatening disease. Optic neuropathy often affects women of African and Caribbean origin. Some authors recommend that patients be treated with high-dose corticosteroids and concurrent immunosuppression from the onset for this manifestation, which may be associated with a poorer outcome., (Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Scleritis is an inflammatory disease of the sclera; outer tunic of the eye on which the oculomotor muscles are inserted. It can be associated with a systemic disease up to one time out of 3. These associated diseases are mainly rheumatoid arthritis, vasculitis, including granulomatosis with polyangiitis in the first line and spondyloarthropathies. Before mentioning such an etiology, it is necessary to eliminate an infectious cause, mainly herpetic, which is regularly underestimated. The classification of scleritis is clinical. We distinguish between anterior scleritis and posterior scleritis. Anterior scleritis is diffuse or nodular, usually of good prognosis. Anterior necrotizing scleritis with inflammation is often associated with an autoimmune disease, necrotizing scleritis without inflammation usually reflects advanced rheumatoid arthritis. The treatment of these conditions requires close collaboration between internists and ophthalmologists to decide on the use of corticosteroid therapy with or without immunosuppressors or biotherapies., (Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

Introduction: Diagnostic work-up of uveitis involves many uncertainties. Search for an etiology should take into account the epidemiology of uveitis and focus on the most severe diseases or those, which can be treated. This work was undertaken to establish recommendations for the diagnosis work-up of uveitis., Methods: Recommendations were developed by a multidisciplinary panel of 15 experts, including internists, ophthalmologists and a rheumatologist and are based on a review of the literature with regard to effectiveness of investigations and the results of the ULISSE study, which is the first prospective study assessing the efficiency of a standardized strategy for the etiological diagnosis of uveitis. Children, immunocompromised patients, severe retinal vasculitis and specific ophthalmological entities are excluded from these recommendations., Results: Investigations should be first guided by the history and physical examination. Serological screening for syphilis is the only test appropriate in all forms of uveitis. If no diagnosis is made after this stage, we propose investigations guided by the anatomic characteristics of uveitis. It includes HLA B27 testing (in unilateral acute anterior non-granulomatous uveitis), serum angiotensin converting enzyme, interferon-gamma release assay and chest CT (chronic uveitis), cerebral MRI and anterior chamber tap with IL10 analysis (intermediate or posterior uveitis in patients over 40 years). Investigations ordered in the absence of orientation are almost always unhelpful., Conclusions: We propose a strategy for the etiologic diagnosis of uveitis. The recommendations should be updated regularly. The efficiency of more invasive investigations has yet to be evaluated., (Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Inflammatory orbitopathies relate to an inflammatory state originating within the orbit and its adnexes, except the inner ocular globe. Orbital inflammation (OI) may be either localized manifestation of a proven or like autoimmune disease, or local response from immune system against infectious, structural or tumoral antigens. We review the clinical manifestations of OI, which provide helpful clues to the diagnosis and describe the inflammatory, infectious and neoplastic conditions classically associated with OI. Autoimmune diseases are probably the most common causes of OI associated with a bilateral dacryoadenitis (e.g., sarcoidosis, granulomatosis with polyangiitis, IgG4-related disease). We focused on a major part of the IgG4-RD spectrum, the IgG4-related orbital disease which has been recently described and the idiopathic orbital inflammation syndrome that one should consider in patients 40 years of age or older with non specific inflammation OI on biopsy but without underlying local or systemic disease. An algorithm for the diagnostic approach of OI was proposed. If systemic explorations fail to diagnose an underlying disease, histopathologic control is required for distinguishing non-specific OI from other differential diagnosis, especially lymphoma. In the cases of pure myositic locations and posteriorly located tumours where biopsy could damage to the optic nerve, analysis of orbital lesions in T2W IRM sequence may be helpful to distinguish idiopathic OI (IOI) from lymphoma. When the diagnostic work-up fails, a corticosteroid trial could be used, but its beneficial effect has to be cautiously interpretated before definitively diagnosing IOI. Finally, treatments used in main infllammatory orbitopathies were also reviewed., (Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI). Published by Elsevier Masson SAS.

Conventional immunosuppressive drugs, anti-TNF alpha and other biotherapies used in clinical practice are capable of controlling non-infectious anterior uveitis, posterior uveitis and panuveitis. The present work has been led by a multidisciplinary panel of experts, internists, rheumatologists and ophthalmologists and is based on a review of the literature. In case of corticodependency or sight-threatening disease, conventional immunosuppressive drugs (methotrexate, azathioprine and mycophenolate mofetil) and/or anti-TNF alpha (adalimumab, infliximab) are used to achieve and maintain remission. Interferon is an efficient immunomodulatory treatment, as a second-line therapy, for some therapeutic indications (refractory macular edema, Behçet's vascularitis). Other biologics, especially tocilizumab, are showing promising results. Local treatments (corticosteroids, sirolimus etc.) are adjuvant therapies in case of unilateral inflammatory relapse. Therapeutic response must be evaluated precisely by clinical examination and repeated complementary investigations (laser flare photometry, multimodal imaging, perimetry, electroretinography measures)., (Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

Despite extensive investigations, including the use of Interferon-gamma release assays (IGRA), the diagnosis of intraocular tuberculosis (TB) remains challenging. Ocular evidence of Mycobacterium tuberculosis in low endemic countries for TB is extremely rare, leading mostly to a TB-related ocular inflammation presumptive diagnosis. This present work aims: to highlights the main clinical patterns suggestive of ocular TB; and the latest recommended guidelines for diagnosing ocular TB to clarify interferon-gamma release assay (IGRA) contribution and accuracy to the management of intraocular TB and its diagnosis, in addition to other available diagnostic tools, such as tuberculin skin test, bacteriologic and histologic analysis from intra/extra ocular sample and radiographic investigations; to define the accuracy of these diagnostic tools according to the endemic TB prevalence; and finally to identify therapeutic strategies adapted to the main clinical presentations of ocular TB. Our review of the literature shows that management of suspected ocular TB differs significantly based on whether patients are from high or low TB prevalence countries since accuracy of chest X-ray, tuberculin skin test and IGRA is significantly different. Taking into account these discrepancies, distinct guidelines should be determined for managing patients with suspected ocular TB, taking into consideration home prevalence of TB-patients., (Copyright © 2018 Société Nationale Française de Médecine Interne (SNFMI).

Interleukin-1 is a major cytokine of innate immunity and inflammation. It exerts various systemic effects during the inflammatory response, such as fever induction, thrombopoiesis and granulopoiesis, or leukocyte recruitment. Its involvement has been demonstrated in many inflammatory-mediated diseases, such as diabetes or gout. Moreover, interleukin-1 plays a pivotal role in some autoinflammatory diseases, such as cryopyrinopathies or familial Mediterranean fever. In these diseases, a constitutional defect of the inflammasome, a protein complex responsible for the activation of interleukin-1, explains the hypersecretion of interleukin-1. Other autoinflammatory diseases have a more complex pathophysiology involving deregulation of the interleukin-1 pathway, upstream or downstream of the inflammasome, or through more complex mechanisms. In this review, we are detailing the synthesis, the activation, the signalling, and the regulation of interleukin-1. We then describe the autoinflammatory diseases or related-diseases where the pathological role of interleukin-1 has been demonstrated., (Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Introduction: The French Agency for Health Safety of Products published recommendations of good practices (RGP) for the treatment of venous thromboembolic disease in 2009. Four of these recommendations apply to the initial management of the disease, with the objective of this study is to determine whether the development and diffusion of the four RGP has had an impact on the practice., Methods: A retrospective before/after study comparing 132 patients treated in emergency department of the Civil Hospices of Lyon for pulmonary embolism (PE) and/or deep venous thrombosis (DVT) in 2008-2009 ("before") and 153 patients in 2010-2011 ("after")., Results: In the "before" period, 70 patients were treated for DVT and 62 patients for PE. In the "after" period, 50 patients were treated for DVT and 103 patients for PE. The compliance rate was not significantly different for the two periods for each RGP except for the indication of low molecular weight Heparin (LMWH) or fondaparinux in the absence of severe renal failure (21% "before" vs. 45% "after"; P=0.02) for patients with PE. Management for the four recommendations was conform for 5.6% of eligible patients in the "before" period and for 3.7% for the "after" period., Conclusion: Our study shows that globally there is no impact of RGP. The reasons appear multiple with first, the mere dissemination and the absence of implementation of these guidelines., (Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

The association between thymoma and autoimmunity is well known. Besides myasthenia gravis, which is found in 15 to 20% of patients with thymoma, other autoimmune diseases have been reported: erythroblastopenia, systemic lupus erythematosus, inflammatory myopathies, thyroid disorders, Isaac's syndrome or Good's syndrome. More anecdotally, Morvan's syndrome, limbic encephalitis, other autoimmune cytopenias, autoimmune hepatitis, and bullous skin diseases (pemphigus, lichen) have been reported. Autoimmune diseases occur most often before thymectomy, but they can be discovered at the time of surgery or later. Two situations require the systematic investigation of a thymoma: the occurrence of myasthenia gravis or autoimmune erythroblastopenia. Nevertheless, the late onset of systemic lupus erythematosus or the association of several autoimmune manifestations should lead to look for a thymoma. Neither the characteristics of the patients nor the pathological data can predict the occurrence of an autoimmune disease after thymectomy. Thus, thymectomy usefulness in the course of the autoimmune disease, except myasthenia gravis, has not been demonstrated. This seems to indicate the preponderant role of self-reactive T lymphocytes distributed in the peripheral immune system prior to surgery. Given the high infectious morbidity in patients with thymoma, immunoglobulin replacement therapy should be considered in patients with hypogammaglobulinemia who receive immunosuppressive therapy, even in the absence of prior infection., (Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

Opportunistic infections (OI) are uncommon in sarcoidosis (1 to 10%) and mostly occur in patients with previously diagnosed disease or can rarely be the presenting manifestation. The most common OIs are, in descending order: aspergillosis, cryptococcosis, and mycobacterial infections. Treatment with corticosteroids is the most frequent risk factor for OI occurrence during sarcoidosis but immunosuppressive drugs and therapy with anti-TNFα are also risk factors. Overall, clinical presentation, treatment, and outcome are identical to that occur in other conditions complicated with the occurrence of OIs. However, some atypical presentations of OIs can mimic sarcoidosis exacerbation and misdiagnosis may lead clinicians to increase immunosuppression, causing worsening of the OI. The meticulous collection of patient's history along with factors differentiating OI from sarcoidosis exacerbation is key factor to optimally manage these patients., (Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Introduction: Several case reports have reported the benefit of intravenous immunoglobulin therapy in many autoimmune diseases, including systemic lupus erythematosus., Case Reports: Here, we report on two cases of lupus myocarditis treated with high dose of intravenous immunoglobulin. The first patient was a 42-year-old woman who presented with lupus myocarditis that was resistant to corticosteroids and cyclophosphamide, and who was finally successfully treated with a single dose of 2 g/kg of intravenous immunoglobulin. The patient displayed clinical improvement a few days later. The second case - a 43-year-old woman was diagnosed with lupus myocarditis and immunosuppressive drugs were contraindicated because of the context of a recent infective endocarditis. She was treated with repeated dose of 2 g/kg of intravenous immunoglobulin. Clinical improvement was observed and the left ventricular ejection fraction increased from 20 % to 60 % within a few days. We also report 9 similar observations identified from a literature review., Conclusion: The use of intravenous immunoglobulin in lupus myocarditis is not officially recognized but could be considered as an alternative when conventional therapies have failed or are contraindicated., (Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Introduction: Gemcitabine-induced thrombotic microangiopathy is a rare event whose management is not yet consensual. The use of eculizumab could be of interest., Case Report: A 68-year-old woman was treated by gemcitabine as adjuvant chemotherapy of a pancreatic adenocarcinoma. Two months later, the patient presented with mechanical hemolytic anemia, thrombocytopenia and high blood pressure that led to the diagnosis of thrombotic microangiopathy. Gemcitabine was stopped. Plasma exchange therapy was introduced since hematological and renal parameters had worsened. As clinical efficacy was insufficient, eculizumab was introduced at a dose of 900 mg per week 4 times, then 1200 mg every 2 weeks. Symptoms along with hematological and nephrological analysis were back to physiological standards after 7 intravenous injections., Conclusion: Eculizumab seems to be an effective treatment against gemcitabine-induced thrombotic microangiopathy in case of severe hematological and renal injuries associated with a lack of response to plasma exchange therapy., (Copyright © 2016 Société Nationale Française de Médecine Interne (SNFMI).

Uveomeningitis relates to an inflammatory state extending from iris and ciliary bodies to the choroid behind the eye. Because of a close contact between eye and brain, and barrier disruption, the inflammation can spread into the central nervous system (CNS). We review the clinical manifestations of uveitis, which are known to provide helpful clues to the diagnosis and describe the infectious, inflammatory, and neoplastic conditions classically associated with the uveomeningitis. Inflammatory or auto-immune diseases are probably the most common clinically recognized causes of uveomeningitis associated with a significant pleiocytosis. These entities often cause inflammation of various tissues in the body, including ocular structures and the meninges (i.e., sarcoidosis, Behçet's disease, and Vogt-Koyanagi-Harada syndrome). The association of an infectious uveitis with an acute or a chronic meningo-encephalitis is unusual but occasionally the eye examination may suggest an infectious etiology or even a specific organism responsible for an uveomeningitis. One should consider the diagnosis of primary ocular-CNS lymphoma in patients of 40 years of age or older with bilateral uveitis, especially with prominent vitritis, showing poor response to corticosteroid therapy. Finally, an algorithm for the diagnostic approach of uveomeningitis is proposed., (Copyright © 2015 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS.

Introduction: Valpromide and sodium divalproate are indicated in the treatment of maniac episodes of bipolar disorder. These drugs are metabolized into valproic acid. The occurrence of peripheral edema has been described as a very rare adverse reaction of those drugs., Case Report: We report the case of a patient treated with valpromide who presented edema of the lower limbs. The increase in furosemide dose allowed regression of edema, and valpromide discontinuation resulted in rapid normalization. Recurrence of mood disorders led to the reintroduction of valpromide, which was associated with recurrence of edema. The definitive withdrawal of valpromide resulted in resolution of edema., Conclusion: Edema of the lower limbs can be induced by valproate. The mechanism of this reaction is unknown. These edema appear to be reversible upon discontinuation of the drug. Clinicians should be aware of a possible relationship between valproate-derived drugs and peripheral edema., (Copyright © 2014 Société nationale française de médecine interne (SNFMI).

Adult-onset Still's disease is a rare and difficult to diagnose multisystemic disorder considered as a multigenic autoinflammatory syndrome. Its immunopathogenesis seems to be at the crossroads between inflammasomopathies and hemophagocytic lymphohistiocytosis, the most severe manifestation of the disease. According to recent insights in the pathophysiology and thanks to cohort studies and therapeutic trials, two phenotypes of adult-onset Still's disease may be distinguished: a systemic pattern, initially highly symptomatic and with a higher risk to exhibit life-threatening complications such as reactive hemophagocytic lymphohistiocytosis, where interleukin-1 blockade seems to be very effective, a chronic articular pattern, more indolent with arthritis in the foreground and less severe systemic manifestations, which would threat functional outcome and where interleukin-6 blockade seems to be more effective. This review focuses on these data., (Copyright © 2014 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.)

Biotherapies used in clinical practice for the treatment of uveitis include monoclonal antibodies and fusion proteins (anti-TNFα, anakinra, tocilizumab and rituximab), interferons (IFN) and intravenous immunoglobulins (IVIg). IFN is capable of inducing prolonged remission and continued after his discontinuation, in 20-40% of patients. Side effects (flu-like, psychological effects) limit its use in practice. Anti-TNFα (infliximab and adalimumab) represents an attractive alternative therapeutic in severe uveitis refractory to immunosuppressants, especially in Behçet's disease. They are generally (>90% of cases) and rapidly effective but their action is often suspensive. Anti-TNFα requires an extended prescription or takes over from another immunosuppressant once ocular inflammation has been controlled. IVIg are used for the treatment of Birdshot's disease. Tolerance of IVIg is good but their efficacy is transient. Rituximab showed an efficacy in few observations of various inflammatory eye diseases (uveitis, scleritis and idiopathic inflammatory pseudo-tumors or associated with granulomatosis with polyangiitis) and cicatricial pemphigoid. The risk of infection limits its use in refractory diseases to conventional therapy. Anakinra (a soluble antagonist of IL-1r) showed interesting results in terms of efficiency in one small open study in Behçet's disease. Its safety profile is good and with a quick action that could be interesting for the treatment of severe uveitis., (Copyright © 2014 Société nationale française de médecine interne (SNFMI).

Purpose: Drug-induced immune haemolytic anemia occurs in one case per million and can be fatal. Our aim was to describe the main characteristics and the type of drug involved., Methods: Cases were retrospectively identified using spontaneous notifications collected by our pharmacovigilance centre and the results of immuno-hematological investigations performed by the laboratory of French blood establishment of Lyon between 2000 and 2012. Inclusion criteria were: an immune (positive direct antiglobulin test), hemolytic, anemia (haemoglobin <100 g/L), with at least a plausible causal relationship with drug exposure according to the French method of imputability or the presence of drug-dependent antibodies, and exclusion of other causes of hemolysis., Results: Ten cases (5 men and 5 women, median age 54.4 years) were identified. Causal drugs were ambroxol, beta-interferon, cefotetan, ceftriaxone, loratadine, oxacillin, oxaliplatine, piperacillin-tazobactam, pristinamycin, and quinine. The median time to onset of anemia after starting the culprit drug was 6 days (2 hours to 16 days). The median nadir of hemoglobin was 57.9 g/L (range: 34-78). The direct antiglobulin test was positive in 8 patients: IgG only (n=4), IgG and complement (n=3), and IgA (n=1). Drug-induced immune haemolytic anemia was considered as definite in 5 cases with positive drug-induced antibodies, probable in 4 cases negative for the detection of drug-induced antibodies but with plausible or likely causal relationship with drug exposure, and probable with an autoimmune mechanism in 1 case., Conclusion: The diagnosis of DIIHA is often difficult because of the similarities with autoimmune haemolytic anemia and the inconstant sensitivity of immunologic tests that sometimes required repetitive assessment., (Copyright © 2014 Société nationale française de médecine interne (SNFMI).

The understanding of the innate immunity, the first line of the host defence, was significantly modified following the sequential discovery of innate immune receptors such as the Toll-like receptors (TLRs) and the NOD-like receptors (NLRs). In response to recognition of microbial patterns or danger signals, some NLRs assemble a multimolecular platform termed as the inflammasome. Inflammasome assembly leads to the activation of the proinflammatory caspase-1. Consequently, an inflammatory immune response is mounted along with a programmed cell death, called pyroptosis. This review summarizes recent advances in the knowledge of the inflammasome and its role in auto-inflammatory diseases, autoimmune diseases, and most common metabolic, cardiovascular or rheumatic diseases., (Copyright © 2014 Société nationale française de médecine interne (SNFMI).

Purpose: To report on the various clinical presentations, etiological diagnosis, prognosis and treatment of patients with scleritis evaluated at a tertiary care eye center., Methods: Retrospective, monocentric study on a series of 32 patients in a tertiary center., Results: The mean age of included patients with scleritis was 46.8 years (range, 22 to 77 years). Nineteen patients were women and 13 were men. Twenty-six patients (81%) had anterior scleritis (15 nodular, 8 diffuse and 3 necrotizing), six (19%) had posterior scleritis. Unilateral inflammation was present in 24 patients (75%). Twelve out of the 32 patients (37.5%) had an underlying systemic disease: granulomatosis with polyangiitis (n=3), Behçet's disease (n=2), unspecified inflammatory arthritis (n=2), psoriatic arthritis (n=1), ankylosing spondylitis (n=1), sarcoidosis (n=1), Cogan's syndrome (n=1) and ulcerative colitis (n=1). Six patients (18.8%) were suspected of having infectious disease with herpes virus: clinical context and positive treatment response with oral valacyclovir. Systemic agents and topical agents were required in 28 patients (87.5%). The first line therapy was mainly oral non-steroidal anti-inflammatory drugs in 15 patients (47%) and oral corticosteroids in 8 (25%). Immunosuppressive drugs were required in 6 patients. The mean follow-up was 16.3 months. Six patients (19%) had a decrease in visual acuity., Conclusion: The number of systemic disease in our series is similar to the main series in the literature. Treatment with valaciclovir might be effective in patients with suspected herpes simplex scleritis., (Copyright © 2013. Published by Elsevier SAS.)

Purpose: Infectious aortic aneurysms are rare conditions, being responsible of 2% of aortic aneurysms. Most published results are surgical case series concerning infected abdominal aorta. In this retrospective study, we assessed clinical features and outcome of patients presenting infectious thoracic aortic aneurysms., Patients and Methods: Diagnosis was based upon a combination of imaging evidence for thoracic aorta aneurysm and evidence for an infective aetiology including a culture of a causative pathogen, or a favourable outcome with anti-infective therapy. Retrospective case series., Results: Six men and one woman were included, with a mean age of 66 years. All the patient presented at least one cardiovascular risk factor or atherosclerosis localisation. Fever (71%) and chest pain (42%) were the most common clinical presenting manifestations. The causative pathogens were: Staphylococcus aureus (N=1), Salmonella enteritidis (N=3) and Candida albicans (N=1). The contrast-enhanced computed-tomography disclosed an aneurysm whose diameter reached more than 50 mm (N=5), that increased rapidly in size (N=5), or presented an inflammatory aspect of the aortic wall (N=4). Management was both medical and interventional: surgery (N=3) or endoluminal repair (N=4). Outcome was favourable in six patients; one patient died from aneurysm-related complications., Conclusion: Clinical manifestations revealing an infectious thoracic aneurysm are variable. Diagnosis should be considered in patients presenting a rapidly-growing aneurysm, especially in the presence of elevated acute phase reactants. Endoluminal repair constitutes a treatment option. The role of FDG-PET for diagnosis and follow-up remains to be defined., (Copyright © 2013 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.)

Purpose: Parvovirus B19 causes erythema infectiosum in children, transient aplastic anemia in patients with hemoglobinopathies, pur red cell aplasia in immunocompromised persons and hydrops fetalis in pregnancy. The spectrum of clinical and biological manifestations in immunocompetent adult continues to grow up., Methods: We report on a case series of 26 patients with primary parvovirus B19 infection in immunocompetent adults. This is a retrospective study over the period 2000 to 2010 in two departments of internal medecine. The diagnostic was clinical, serological or molecular., Results: There was a female predominance (sex-ratio 3.33/1). Median patient age at diagnostic was 38.8 years (range: 18-68). The predominant symptoms were fever (65%), peripheral and symmetrical polyarthralgia (62%) and skin rash (58%). Two patients had neurological manifestations (sixth cranial nerve palsy, distal paresthesia) and one patient had myocarditis. Abnormal laboratory values included increased acute phase reactants (73%), thrombocytopenia (43%), lymphopenia (38%) and elevated liver enzymes (37%). Antinuclear (19%), anti-DNA (28%) and anti-phospholipids antibodies (14%), and hypocomplementemia (32%) were observed. False reaction with anti-CMV and anti-EBV IgM positivity was documented in 27% of cases. Two patients had persistent parvovirus B19 infection., Conclusion: The diversity of the clinical manifestations of parvovirus B19 infection may be misleading for the clinician. However, the diagnosis should be suspected in immunocompetent adults to limit the risk of transmission to the patients who could develop a severe infection such as pregnant women or immunocompromised patients., (Copyright © 2013 Société nationale française de médecine interne (SNFMI).

Primary immunodeficiency with granulomatosis in the adulthood mainly concern common variable immunodeficiency (CVID). Hypogammaglobulinemia in the adulthood is usually related to a secondary immunodeficiency. When a patient presents with the association of a hypogammaglobulinemia and a granulomatosis, an opportunistic infection must first be ruled out. For unknown reasons, about 10% of the patients affected by CVID also present with granulomatosis. Lesions usually affect the pulmonary tract or the mediastinum. Half of these patients are also affected by an autoimmune cytopenia. Treatment is not codified. Severe pulmonary complications can occur in about 50% of the patients., (Copyright © 2012 Société nationale française de médecine interne (SNFMI). Published by Elsevier SAS. All rights reserved.)

Although primary immunodeficiencies (PID) are typically marked by increased susceptibility to infections, autoimmune manifestations have increasingly been recognized as an important component of several forms of PID. Here, we discuss two forms of PID in which autoimmune cytopenias are particularly common and may be the first manifestation of the disease in adults: autoimmune lymphoproliferative syndrome (ALPS) and common variable immunodeficiency (CVID). Approximately one fifth of patients with CVID develop autoimmune diseases, and immune thrombocytopenic purpura (ITP) and autoimmune hemolytic anemia (AHA) are the most common. Since autoimmune cytopenias frequently precede the diagnosis of CVID, testing for immunoglobulin levels should be performed in patients diagnosed with AITP and AHA. Patients with CVID in association with autoimmune cytopenias have a "particular phenotype" with lower susceptibility to infection and higher susceptibility to autoimmune manifestations and, for patients with AHA, a more frequent development of splenomegaly and lymphoma. Corticosteroids and high doses of intravenous immunoglobulins (IVIg) seem to have the same efficacy as in idiopathic AITP and AHA. Splenectomy and rituximab are as effective as in idiopathic autoimmune cytopenias but are associated with an increased risk of severe infection and should, in our opinion, be considered only for those rare patients with "refractory diseases". The course and outcome of autoimmune cytopenias is not affected by supportive IVIg therapy. Autoimmune destruction of blood cells affects over 70% of ALPS patients. The median age of first presentation is 24 months of age, but with increasing awareness of this condition, adults with autoimmune cytopenias are now being diagnosed more frequently. Testing for ALPS should therefore be considered in young adults with unexplained Evan's syndrome. Patients usually respond to immunosuppressive medications, including corticosteroids. Unlike many patients with idiopathic autoimmune cytopenias, the cytopenias in patients with ALPS typically do not respond to IVIg. After corticosteroids, the immunosuppressive drug that is the most studied in ALPS patients is mycophenolate mofetyl. Rituximab and splenectomy are relatively contraindicated in ALPS because of an increase risk of severe infection and should be reserved for patients who fail all other therapies., (Copyright © 2012.

Uveitis is a common (20-50%) and early manifestation of sarcoidosis. Typical sarcoid uveitis presents with bilateral mutton fat keratic precipitates, iris nodules, and anterior and posterior synechia. Posterior involvement includes vitreitis, vasculitis and choroidal lesions. Long-term complications are common, and cystoid macular edema is the most important and sight-threatening consequence. Diagnostic work-up of sarcoidosis usually includes chest radiography or computed tomography scan, bronchoscopy with bronchoalveolar lavage, angiotensin converting enzyme, lysozyme, gallium scintigraphy and biopsy. The gold standard for the diagnosis of sarcoidosis should be obtained with histologic examination. However, an international workshop has recently established diagnostic criteria of "intraocular sarcoidosis" (sarcoidosis uveitis) on the basis of a combination of suggestive ophthalmological findings and laboratory tests, when biopsy is not performed or is negative. More recent techniques such as PET-scan and endoscopic ultrasound-guided fine-needle biopsy of intrathoracic nodes should be assessed in future prospective studies. Corticosteroids are the mainstay of treatment. Anterior and unilateral intermediate or posterior uveitis are usually treated with topical corticosteroids. Systemic corticosteroids are indicated in uveitis not responding to topical corticosteroids or in the presence of bilateral posterior involvement, especially with macular edema and occlusive vasculitis. In 5 to 20% of the patients who are corticosteroids resistant or require an unacceptable dose to maintain remission, additional immunosuppression is used, including methotrexate, leflunomide and mycophenolate mofetil. As in systemic sarcoidosis, infliximab has been recently suggested for refractory or sight threatening disease., (Copyright © 2010 Société nationale française de médecine interne (SNFMI).

Kawasaki disease (KD) is a multisystemic vasculitis affecting mainly the skin, mucosa, and lymph nodes. Coronary artery aneurysms occur in 25% of patients but their prevalence is reduced to 4% in those patients treated with intravenous immunoglobulin (IVIg) within 10 days of illness onset. Interesting data recently published relate to physiopathology and diagnosis of the disease. Investigations identified an antigen-driven IgA oligoclonal response directed against cytoplasmic inclusions in KD tissues. An algorithm using laboratory tests and echocardiography has been recently proposed to improve early detection of incomplete KD. Although KD predominantly affects children, it may be also of interest for adult physicians. First, patients may develop long-term cardiovascular event. Coronary artery aneurysms may lead to the development of coronary stenosis or thrombosis. Despite the absence of coronary lesions during the acute phase of the disease, patients may present morphological and functional sequelae of coronary and peripheral arteries at convalescent phase. These potential arterial sequelae require long-term follow-up and treatment of associated cardiovascular risk factors. Although the level of injury seems to be correlated with the severity of initial coronary lesions, long-term course of vascular injuries is poorly known. Second, KD may occur in adults with 91 cases reported in the literature. Twenty-one cases have been reported in HIV infected patients. Intravenous immunoglobulins appear to shorten the disease course. Recent studies highlight the existence of incomplete KD and symptomatic coronary aneurysms in adults. Overall, these data suggest that adult patients with biological or echocardiographic features suggestive of incomplete KD should receive prompt IVIg to prevent coronary artery sequelae., (Copyright © 2010 Société nationale française de médecine interne (SNFMI).

Purpose: Uveitis consists of a large group of diseases characterized by intraocular inflammation involving the uveal tract. This heterogeneity makes the diagnosis and the treatment of uveitis frequently challenging. The purpose of this study was to describe the various clinical and etiologic aspects of uveitis, through the new standardized uveitis classification and the use of modern investigations for its diagnostic work-up., Methods: The medical records of 121 new patients with uveitis referred to our tertiary ophthalmologic centre between January 2002 and December 2006 were retrospectively reviewed. Uveitis associated to human immunodeficiency virus and secondary to exogenous endophthalmitis were excluded. All patients had a complete ophthalmological examination and appropriate clinical and paraclinical examination. The diagnosis was established according to the recent international criteria., Results: One hundred and twenty-one patients were included. The four main etiologies were: toxoplasmosis (14%), sarcoidosis (11.6%), spondylarthritis or HLA B27-associated uveitis (13.2%) and Herpes virus infections (9.1%) that represented almost half of the uveitis causes (47.9%). Various diseases constituted the remaining causes of the uveitis (20.9%). Uveitis remained unexplained in the remaining 36 patients (29.7%). Overall, associated systemic diseases were diagnosed in 35.5% of our uveitis patients (34 patients), associated infectious conditions in 26.4% (32 patients) and specific ocular diseases in 8.3% (12 patients)., Conclusion: Despite a limited number of patients, our study showed an etiologic distribution similar to that of the main series reported in the literature. Nevertheless, we observed an elevated frequency of sarcoidosis and systemic diseases, which emphasizes a management that takes into account standardized clinical and paraclinical criteria and the usefulness of a collaboration with the internist., (Copyright © 2010 Société nationale française de médecine interne (SNFMI).

Introduction: Hypereosinophilic syndromes rarely manifest as polyserositis. Imatinib mesylate is the reference treatment for myeloid variants of FIP1L1-PDGFRA-positive hypereosinophilic syndromes. A response to imatinib has also been reported in FIP1L1-PDGFRA-negative hypereosinophilic syndromes., Case Report: We report a 25-year-old man who presented with a FIP1L1-PDGFRA-negative hypereosinophilic syndrome, with severe pericardial effusion and bilateral pleuritis. Imatinib mesylate at the dose of 100mg daily was started because of high-dose corticosteroids dependence. A response was noted after 15 days of treatment. Corticosteroids were discontinued after 7 months and the patient remained asymptomatic after 23 months of treatment., Conclusion: This report evidences the association of polyserositis with hypereosinophilic syndromes and the potential efficacy of imatinib mesylate even in FIP1L1-PDGFRA-negative patients., (Copyright 2010 Société nationale française de médecine interne (SNFMI).

In developed countries, uveitis is quite common and chronic course is associated with a poor visual prognosis. However, no guidelines for their management have been consensually proposed. Based on the experience of ophthalmologists and internists from tertiary care centers, this article describes the management of uveitis, including the diagnostic procedure, indications and types of anti-inflammatory treatments. We focus on the interest of an exhaustive ophthalmologic examination for the diagnosis of an underlying systemic disease such as sarcoidosis. In this way, a multidisciplinary staff could be useful for an optimal management of uveitis. We also reviewed the main current treatments for severe uveitis. Whatever the origin of ocular inflammation, corticosteroids are consensually used as first line treatment. However, the identification of an underlying systemic disease helps in the refinement of further therapeutic choices. In cases of refractory and sight threatening uveitis, the short-term use of infliximab, a chimeric anti-TNF-alpha antibody, has been shown to be effective and safe. These recommendations do not constitute treatment guidelines but aim at improving the uniformity of clinical practice for the management of uveitis, until higher levels of evidence are obtained.

Ectopic adrenocorticotropic (ACTH) syndrome is a rare condition, generally due to lung or carcinoid tumors. 18-fluorodeoxy-glucose positron emission tomography ((18)FDG-PET) can be useful where conventional localization techniques often fail. A 50-year-old man presented with sudden diffuse oedema, hypokaliemic alkalosis, Diabetes mellitus and high serum levels of ACTH and cortisol. Ectopic ACTH syndrome was confirmed leading to ketoconazole treatment. Chest-computed tomography only revealed an aspecific anterior mediastinal nodule that was hypermetabolic on the whole body-(18)FDG-PET. A thymic tumor was suspected and the patient had a thymectomy that revealed an atypical carcinoid tumor with pleural carcinosis. The postoperative course was favorable with clinical and biochemical remission of neoplastic Cushing's syndrome.
