[Messages from the estates general on French internal medicine]. / Que retenir des états généraux de la médecine interne française ?

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.

[Immune-related adverse events after immune checkpoints inhibitors in 2019: An update]. / Toxicités immunologiques induites par les inhibiteurs de checkpoint en 2019 : mise au point.

Use of checkpoint inhibitors to treat cancer was one of the most important revolution these last years and an increasing number of new types of tumors is currently under investigation with these new treatments. However, immune-related adverse events associated with these agents frequently affect various organs, mimicking auto-immune or inflammatory diseases. Some of these effects can be severe, often requiring hospitalization and specialized treatment (immunosuppression). Most known agents are ipilimumab (anti-CTLA-4 antibody) nivolumab and pembrolizumab (anti-PD-1 antibodies). New molecules are now approved or in development as anti-PD-L1 antibodies, anti-LAG-3 or anti-TIM-3 antibodies, increasing the probability and new description of immune-related adverse events. With his experience in auto-immune diseases, the immunologist/internal medicine specialist has an important role in the management of these toxicities. The goal of this review is to focus on the incidence, diagnostic assessment and recommended management of the most relevant immune-related adverse events.

[Management of myelodysplastic syndromes in 2019: An update]. / Prise en charge des syndromes myélodysplasiques en 2019 : mise au point.

Myelodysplastic syndromes are a heterogeneous group of clonal myeloid disorders characterized by peripheral cytopenias and an increased risk of progression to acute myeloid leukemia. Inflammatory, auto-immune or syndromic symptoms can make the diagnosis difficult. Diagnosis is currently based on bone marrow cytology but cytogenetics and molecular features are currently overpassing their initial prognostic function (allowing early diagnosis and prediction of therapeutic response). The prognostic classification is based on the Revised International Prognostic Scoring System, which also provides guidance for therapeutic management. The treatment of low-risk myelodysplastic syndromes is based on the correction of cytopenias (erythropoiesis stimulating agents, transfusions, lenalidomide, etc.), whereas in high-risk group, the goal is the control of the leukemic clone (hypomethylating agents, allograft of hematopoietic stem cell transplantation). Other molecules are used to manage complications of cytopenias or transfusion (anti-infectious prophylaxis and treatments, martial chelation). New molecules are being studied with some interesting results (luspatercept, venetoclax). This article aims to provide an update on the knowledge that an internist should know for the practical management of myelodysplastic syndromes in 2019.

Risk factors for bleeding, including platelet count threshold, in newly diagnosed immune thrombocytopenia adults.

Essentials Risk factors of bleeding in adult immune thrombocytopenia are not known. This multicenter study assessed risk factors of bleeding at immune thrombocytopenia onset. Platelet count thresholds associated with bleeding were < 20 × 109 L-1 and < 10 × 109 L-1 . Exposure to anticoagulants was a major risk factor of severe bleeding. SUMMARY: Background The aim of this cross-sectional study was to assess risk factors for bleeding in immune thrombocytopenia (ITP) adults, including the determination of platelet count thresholds. Methods We selected all newly diagnosed ITP adults included in the Cytopénies Auto-immunes Registre Midi-PyrénéEN (CARMEN) register and at the French referral center for autoimmune cytopenias. The frequencies of any bleeding, mucosal bleeding and severe bleeding (gastrointestinal, intracranial, or macroscopic hematuria) at ITP onset were assessed. Platelet count thresholds were assessed by the use of receiver operating characteristic curves. All potential risk factors were included in logistic regression models. Results Among the 302 patients, the frequencies of any, mucosal and severe bleeding were 57.9%, 30.1%, and 6.6%, respectively. The best discriminant threshold of platelet count for any bleeding was 20 × 109 L-1 . In multivariate analysis, factors associated with any bleeding were platelet count (< 10 × 109 L-1 versus ≥ 20 × 109 L-1 , odds ratio [OR] 48.2, 95% confidence interval [CI] 20.0-116.3; between 10 × 109 L-1 and 19 × 109 L-1 versus ≥ 20 × 109 L-1 , OR 5.2, 95% CI 2.3-11.6), female sex (OR 2.6, 95% CI 1.3-5.0), and exposure to non-steroidal anti-inflammatory drugs (NSAIDs) (OR 4.8, 95% CI 1.1-20.7). A low platelet count was also the main risk factor for mucosal bleeding. Exposure to anticoagulant drugs was associated with severe bleeding (OR 4.3, 95% CI 1.3-14.1). Conclusions Platelet counts of < 20 × 109 L-1 and < 10 × 109 L-1 were thresholds for major increased risks of any and mucosal bleeding. Platelet count, female sex and exposure to NSAIDs should be considered for assessment of the risk of any bleeding. Exposure to anticoagulant drugs was a major risk factor for severe bleeding.

Bone marrow involvement in systemic lupus erythematosus.

BACKGROUND: Besides peripheral cytopenias, bone marrow abnormalities, such as fibrosis, pure red cell aplasia and aplastic anemia have been reported in patients with systemic lupus erythematosus (SLE), suggesting that bone marrow may be a 25 target organ in SLE. AIM: Our objective was to describe this bone marrow involvement. METHODS: This registry is a nationwide retrospective study. Centers provided data concerning medical history, SLE manifestations, type of hematologic disorder, treatments and outcome. Bone marrow aspirations and/or biopsies were transferred for centralized review. RESULTS: Thirty patients from 19 centers were included. Central hematologic manifestations comprised bone marrow fibrosis (n = 17; 57%), pure red cell aplasia (n = 8; 27%), myelodysplastic syndrome (n = 3; 10%), aplastic anemia and agranulocytosis (n = 1; 3% each). Bone marrow involvement was diagnosed concomitantly with SLE in 12 patients. Bone marrow biopsies showed fibrosis in 19 cases, including one case of pure red cell aplasia and one case of agranulocytosis and variable global marrow cellularity. Treatments included corticosteroids (90%), hydroxychloroquine (87%), rituximab (33%), intravenous immunoglobulins (30%), mycophenolate mofetil (20%) and ciclosporine (20%). After a median follow-up of 27 months (range: 1-142), 24 patients manifested complete improvement. No patient died. CONCLUSIONS: This registry comprises the largest series of SLE patients with bone marrow involvement. It demonstrates the strong link between SLE and bone marrow fibrosis. Patients with atypical or refractory cytopenia associated with SLE should undergo bone marrow examination to enable appropriate, and often effective, treatment. Long-term prognosis is good.

Lenalidomide with or without erythropoietin in transfusion-dependent erythropoiesis-stimulating agent-refractory lower-risk MDS without 5q deletion.

After failure of erythropoiesis-stimulating agents (ESAs), lenalidomide (LEN) yields red blood cell (RBC) transfusion independence (TI) in 20-30% of lower-risk non-del5q myelodysplastic syndrome (MDS). Several observations suggest an additive effect of ESA and LEN in this situation. We performed a randomized phase III study in 131 RBC transfusion-dependent (TD, median transfusion requirement six RBC units per 8 weeks) lower-risk ESA-refractory non-del5q MDS. Patients received LEN alone, 10 mg per day, 21 days per 4 weeks (L arm) or LEN (same schedule) + erythropoietin (EPO) beta, 60,000 U per week (LE arm). In an intent-to-treat (ITT) analysis, erythroid response (HI-E, IWG 2006 criteria) after four treatment cycles (primary end point) was 23.1% (95% CI 13.5-35.2) in the L arm and 39.4% (95% CI 27.6-52.2) in the LE arm (P=0.044), while RBC-TI was reached in 13.8 and 24.2% of the patients in the L and LE arms, respectively (P=0.13). Median response duration was 18.1 and 15.1 months in the L and LE arms, respectively (P=0.47). Side effects were moderate and similar in the two arms. Low baseline serum EPO level and a G polymorphism of CRBN gene predicted HI-E. Combining LEN and EPO significantly improves erythroid response over LEN alone in lower-risk non-del5q MDS patients with anemia resistant to ESA.

FDG-PET/CT findings in systemic mastocytosis: a French multicentre study.

INTRODUCTION: Mastocytosis is a clonal haematological disease characterized by uncontrolled proliferation and the activation of mast cells. The value of FDG-PET/CT (FDG-PET) in mastocytosis has yet to be determined. METHODS: We retrospectively identified patients with an established diagnosis of systemic mastocytosis (SM), according to the WHO criteria, who underwent PET using the French Reference Centre for Mastocytosis database. Semi-quantitative and visual analysis of FDG-PET was performed and compared to the clinico-biological data. RESULTS: Our cohort included 19 adult patients, median age 65 years [range 58-74], including three with smouldering SM (SSM), three with aggressive SM (ASM), 10 with an associated clonal haematological non-mast-cell lineage disease (SM-AHNMD), and three with mast cell sarcoma (MCS). FDG-PET was performed at the time of the SM diagnosis (15/19), to evaluate lymph node (LN) activity (3/19) or the efficacy of therapy (1/19). FDG uptake was observed in the bone marrow (BM) (9/19, 47%), LN (6/19, 32%), spleen (12/19, 63%), or liver (1/19, 5%). No significant FDG uptake was observed in the SSM and ASM patients. A pathological FDG uptake was observed in the BM of 6/10 patients with SM-AHNMD, appearing as diffuse and homogeneous, and in the LN of 5/10 patients. All 3 MCS patients showed intense and multifocal BM pathological uptake, mimicking metastasis. No correlation was found between the FDG-PET findings and serum tryptase levels, BM mast cell infiltration percentage, and CD30 and CD2 expression by mast cells. CONCLUSIONS: FDG uptake does not appear to be a sensitive marker of mast cell activation or proliferation because no significant FDG uptake was observed in most common forms of mastocytosis (notably purely aggressive SM). However, pathological FDG uptake was observed in the SM-AHNMD and in MCS cases, suggesting a role of FDG-PET in their early identification and as a tool of therapeutic assessment in this subgroup of patients.

Accuracy of physician assessment of treatment preferences and health status in elderly patients with higher-risk myelodysplastic syndromes.

Higher-risk myelodysplastic syndromes (MDS) are rarely curable and have a poor prognosis. We investigated the accuracy of physicians' perception of patients' health status and the patients' preferences for involvement in treatment decisions. We examined 280 newly diagnosed higher-risk elderly MDS patients paired with their physicians. Survey tools included the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and the Control Preference Scale. Overall concordance was 49% for physician perception of patient preferences for involvement in treatment decisions. In 36.4% of comparisons there were minor differences and in 14.6% there were major differences. In 44.7% of the patients preferring a passive role, physicians perceived them as preferring an active or collaborative role. Absence of the patient's request for prognostic information (P=0.001) and judging the patient as having a poor health status (P=0.036) were factors independently associated with the physicians' attitude toward a lower degree of patient involvement in clinical decisions. Agreement on health status was found in 27.5% of cases. Physicians most frequently tended to overestimate health status of patients who reported low-level health status. The value of decision aid-tools in the challenging setting of higher-risk MDS should be investigated to further promote patient-centered care.

Impact of an oncogeriatric consulting team on therapeutic decision-making.

Increased life expectancy and cancer incidence imply the need to develop a specialized care policy for elderly patients with cancer. We created an oncogeriatric consulting team (OGCT) in Toulouse University Hospital to carry out comprehensive gerontological assessment at the bedside of hospitalized patients. We analyze the impact on the final cancer treatment decision of this mobile geriatric assessment. We carried out a descriptive, retrospective real-life analysis of a patient cohort over a two-year period. The OGCT assessed 124 patients, of whom the majority were women (54.8%), median age 81 years, living at home (95.2%) and with family caregivers (86.5%). Nearly all were frail (96.7% according to the classification of Balducci and colleagues) and 3.2% were vulnerable. The team's decisions were analyzed for patients who had not yet been treated (n=107). After analysis, the team's proposal was in line with the initial cancer treatment plan in 68.2% of cases (n=73). In cases where there was a disagreement, the final decision was in line with the mobile team's proposal in 17.75% of 107 patients (n=19). The decision of the team was followed more often when their assessment proposed strictly palliative treatment. The decision to give elderly patients specific cancer treatment seems in our experience rather to be a matter for the oncologists, and is not very susceptible to modification by geriatric opinion. On the other hand, the geriatrician appears to be more credible and his/her opinion more likely to be followed when the patient is considered too frail and less aggressive, or even exclusively palliative, treatment is proposed.

Long-term outcome of anemic lower-risk myelodysplastic syndromes without 5q deletion refractory to or relapsing after erythropoiesis-stimulating agents.

A large proportion of lower-risk myelodysplastic syndromes (MDS) respond to erythropoiesis-stimulating agents (ESA), but most responses are transient. We updated a previously reported cohort of lower-risk MDS patients treated with ESA and analyzed outcomes after ESA failure. In 120 patients with primary resistance and 66 patients with relapse after an initial response to ESA, the 5-year cumulative incidence of acute myeloid leukemia (AML) after failure was 18.9% and 11.6%, respectively (P=0.20). Median overall survival (OS) after failure was 40.1 and 44.9 months (P=0.35), respectively. We further categorized patients as 'early failures' (including resistance and relapse after <6 months of response), or 'later failures' (that is, relapse after ≥6 months). The 5-year cumulative incidence of AML and median OS after failure in early and later failure were 21.6% and 9% (P=0.02) and 36.7 and 54.3 months (P=0.02), respectively. Early failure to ESA and a baseline diagnosis of refractory anemia with excess blasts (RAEB)-1 were independent prognostic factors for AML progression and, along with trisomy 8, for shorter OS. Median OS from treatment onset was 40, 90.7 and 65.8 months in early failure, later failure and no relapse, respectively (P=0.001). Lower-risk MDS with early failure to ESA have a relatively unfavorable outcome, and should be offered alternative treatments.

High response rate and improved exercise capacity and quality of life with a new regimen of darbepoetin alfa with or without filgrastim in lower-risk myelodysplastic syndromes: a phase II study by the GFM.

Darbepoetin (DAR), with or without granulocyte colony-stimulating factor (G-CSF), has proved effective in treating anemia in patients with lower-risk myelodysplastic syndrome (MDS), but its effects on quality of life (QoL) and exercise functioning are less well established. In this phase II study (no. NCT00443339), lower-risk MDS patients with anemia and endogenous erythropoietin (EPO) level <500 IU/L received DAR 500 µg once every 2 weeks for 12 weeks, with G-CSF added at week 12 in non-responders. Physical performance was assessed with the 6-min walking test and, for fit patients, maximal oxygen consumption (VO2max). QoL was evaluated using SF-36 and FACT-An tests. In 99 patients, erythroid response rate according to IWG 2006 criteria was 48 and 56 % at 12 and 24 weeks, respectively. Addition of G-CSF rescued 22 % of non-responders. In 48 % of the responders, interval between darbepoetin injections could be increased for maintenance treatment. Serum EPO level was the only independent predictive factor of response at 12 weeks, and its most discriminant cutoff value was 100 IU/L. QoL and VO2max showed improvement over time in responders, compared with non-responders. With a median follow-up of 52 months, median response duration was not reached, and 3-year cumulative incidence of acute myeloid leukemia and overall survival (OS) was 14.5 and 70 %, respectively. Baseline transfusion dependence, International Prognostic Score System (IPSS), and Revised IPSS accurately predicted OS from treatment onset. Tolerance of darbepoetin was good. In conclusion, this regimen of darbepoetin every 2 weeks yielded high response rates and prolonged response duration. Objective improvement in exercise testing and in patient-reported QoL confirms the clinical relevance of anemia correction with erythropoiesis-stimulating agents.

Diffuse pulmonary uptake on FDG-PET with normal CT diagnosed as intravascular large B-cell lymphoma: a case report and a discussion of the causes of diffuse FDG uptake in the lungs.

A 71-year-old woman was admitted to our hospital with asthenia, weight loss, fever, cognitive impairment and shortness of breath. Physical examination showed hemiparesis and cerebellar ataxia. There was no superficial lymphadenopathy. Blood tests showed raised levels of C-reactive protein and lactate dehydrogenase. Bone marrow aspiration and biopsy were negative. [18F]fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) showed intense uptake within a right apical nodule and intense and diffuse uptake of FDG in the lungs without corresponding structural CT abnormality. Lung biopsy showed intravascular large B-cell lymphoma (IVLBCL). FDG-PET findings in IVLBCL and causes of diffuse FDG lung uptake with and without CT abnormalities are discussed.

Does addition of erythropoiesis stimulating agents improve the outcome of higher-risk myelodysplastic syndromes treated with azacitidine?

We studied a retrospective cohort of 282 higher-risk MDS treated with azacitidine, including 32 patients who concomitantly received an ESA for a median of 5.8 months after azacitidine onset. Forty-four percent of ESA and 29% of no-ESA patients reached HI-E (p=0.07); 48% and 20% achieved transfusion independence (p=0.01). Median OS was 19.6 months in the ESA and 11.9 months in the no-ESA groups (p=0.04). Addition of an ESA significantly improved OS (p=0.03) independently of azacitidine schedule and duration, and of our proposed azacitidine risk score (Blood 2011;117:403-11). Adding an ESA to azacitidine in higher-risk MDS should be studied prospectively.

[Antiphospholipid antibodies and the risk of thrombosis: a comparative survey between chronic immune thrombocytopenia and primary antiphospholipid syndrome]. / Profil des anticorps antiphospholipides et risque de thrombose : étude comparative entre thrombopénie immunologique chronique et syndrome des antiphospholipides primaire.

PURPOSE: The prevalence of antiphospholipid antibodies (APA) in patients with immune thrombocytopenic purpura (ITP) varies from 25 to 75% in the literature. The risk of thrombosis in this subgroup of patients is debated. In parallel, thrombocytopenia is present in 22 to 42% of patients with antiphospholipid syndrome (APS). PATIENTS AND METHODS: The main study objective was to compare the profile at diagnosis of lupus anticoagulant (LA), anticardiolipin antibody (ACL) and anti-ß(2)GP-I antibody between a cohort of 93 chronic ITP patients and a cohort of 27 primary APS patients. The secondary objectives were: to evaluate the risk of thrombosis in ITP patients depending on the presence of APA; to compare the profile of APA and to assess the occurrence of lupus in APS patients depending on the presence of thrombocytopenia. RESULTS: In ITP patients, the prevalence of APA was 25%; association of several different APA was less frequent than in APS patients; mean titles of ACL and anti-ß(2)GP-I antibodies were comparable between the two cohorts; two spontaneous venous thromboses occurred in ITP patients, with no particular profile of APA (median follow-up: 36 months). Thrombocytopenia was present in 26% of APS patients; it was always moderate and asymptomatic, and sometimes intermittent; no particular profile of APA was associated to thrombocytopenia; only one thrombocytopenic patient developed a systemic lupus and no particular profile of APA could be found associated (median follow-up: 48 months). CONCLUSION: ITP patients with APA have less frequently an association of different APA than APS patients do; their risk of thrombosis appears low.

Ferritin level at diagnosis is not correlated with poorer survival in non RBC transfusion dependent lower risk de novo MDS.

We evaluated the prognostic value of serum ferritin (SF) level at diagnosis in 318 newly diagnosed IPSS low and int 1 (lower) risk MDS patients included in the French MDS registry, who did not require RBC transfusions and had baseline SF level determination. Increased baseline SF level (>300 ng/ml) was correlated with male gender, more pronounced anaemia, and diagnosis of RARS but had no negative impact on progression to AML or survival.

Impact of TET2 mutations on response rate to azacitidine in myelodysplastic syndromes and low blast count acute myeloid leukemias.

The impact of ten-eleven-translocation 2 (TET2) mutations on response to azacitidine (AZA) in MDS has not been reported. We sequenced the TET2 gene in 86 MDS and acute myeloid leukemia (AML) with 20-30% blasts treated by AZA, that is disease categories wherein this drug is approved by Food and Drug Administration (FDA). Thirteen patients (15%) carried TET2 mutations. Patients with mutated and wild-type (WT) TET2 had mostly comparable pretreatment characteristics, except for lower hemoglobin, better cytogenetic risk and longer MDS duration before AZA in TET2 mutated patients (P=0.03, P=0.047 and P=0.048, respectively). The response rate (including hematological improvement) was 82% in MUT versus 45% in WT patients (P=0.007). Mutated TET2 (P=0.04) and favorable cytogenetic risk (intermediate risk: P=0.04, poor risk: P=0.048 compared with good risk) independently predicted a higher response rate. Response duration and overall survival were, however, comparable in the MUT and WT groups. In higher risk MDS and AML with low blast count, TET2 status may be a genetic predictor of response to AZA, independently of karyotype.
