Amoxicillin Blood Concentration in High-Dose Intravenous Discontinuous Amoxicillin: Look Beyond Numbers. Max-Amox Study.

Purpose: High doses of amoxicillin are recommended to treat severe infections such as endocarditis. Amoxicillin causes dose-dependent toxicities, in particular crystal nephropathy. Toxicity could be avoided by monitoring of amoxicillin trough plasma concentrations (ATPC).

pneumonia in non-HIV patients: need for a more extended prophylaxis.

Background: pneumonia (PCP) has a significant mortality rate for non-HIV immunocompromised patients. Prevention is primarily based on combined trimethoprim and sulfamethoxazole (TMP-SMX) but guidelines on pneumocystosis prophylaxis are scattered and not consensual.

Objectives: This study aims to describe PCP in non-HIV patients and to review case by case the prior indication of prophylaxis according to specific guidelines.

Eicosanoids and Oxylipin Signature in Hereditary Hemochromatosis Patients Are Similar to Dysmetabolic Iron Overload Syndrome Patients but Are Impacted by Dietary Iron Absorption.

Introduction: Oxylipins are mediators of oxidative stress. To characterize the underlying inflammatory processes and phenotype effect of iron metabolism disorders, we investigated the oxylipin profile in hereditary hemochromatosis (HH) and dysmetabolic iron overload syndrome (DIOS) patients.

Methods: An LC-MS/MS-based method was performed to quantify plasma oxylipins in 20 HH and 20 DIOS patients in fasting conditions and 3 h after an iron-rich meal in HH patients.

Immunohistochemical expression of DnaJ homolog subfamily B member 9 in immunoglobulin G4-related disease: a pilot study.

Objectives: DnaJ homolog subfamily B member 9 (DNAJB9) is a co-chaperone protein that governs the functions and integrity of cells. In immunoglobulin G4-related disease (IgG4-RD), DNAJB9 was shown to be upregulated in plasma cells, but its immunohistochemical expression has never been explored. This pilot study aims to investigate the immunohistochemical distribution and intensity of DNAJB9 in IgG4-RD tissue specimens.

Dupilumab for relapsing or refractory sinonasal and/or asthma manifestations in eosinophilic granulomatosis with polyangiitis: a European retrospective study.

Background: Eosinophilic granulomatosis with polyangiitis (EGPA) is often associated with glucocorticoid-dependent asthma and/or ear, nose and throat (ENT) manifestations. When immunosuppressants and/or mepolizumab are ineffective, dupilumab could be an option. We describe the safety and efficacy of off-label use of dupilumab in relapsing and/or refractory EGPA.

Combining thrombopoietin receptor agonists with immunosuppressive drugs in adult patients with multirefractory immune thrombocytopenia, an update on the French experience.

Combining drugs could be an effective option for treating multirefractory ITP, that is, patients not responding to rituximab, thrombopoietin receptor agonists (TPO-RA) and splenectomy. We conducted a retrospective, multicenter, observational study including multirefractory ITP patients who received a combination of a TPO-RA and an immunosuppressive drug. We included 39 patients (67% women, median age 59 years [range 21-96]), with a median ITP duration of 57 months [3-393] and a median platelet count at initiation of 10 × 10 /L [1-35].

Rituximab vs Cyclophosphamide Induction Therapy for Patients With Granulomatosis With Polyangiitis.

Importance: Results of randomized clinical trials have demonstrated rituximab's noninferiority to cyclophosphamide as induction therapy for antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV), with neither treatment having a specific advantage for granulomatosis with polyangiitis (GPA). However, post hoc analysis results have suggested that rituximab might be more effective than cyclophosphamide in inducing remission in patients with proteinase 3-positive AAV.

Objective: To compare the effectiveness of rituximab and cyclophosphamide in inducing GPA remission in a large population of unselected patients.

Prediction of Iron Deficiency Anemia in Third Trimester of Pregnancy Based on Data in the First Trimester: A Prospective Cohort Study in a High-Income Country.

Background: Systematic iron supplementation may be harmful in pregnant women with non-depleted iron. Our objectives were to estimate the prevalence of anemia at the third trimester of pregnancy (T3) and to identify the parameters at the first trimester (T1), which best predict anemia at T3. Methods: This prospective cohort study in France included pregnant women at T1 without non-iron deficiency anemia.

Intravenous Immunoglobulins Tapering and Withdrawal in Systemic Capillary Leak Syndrome (Clarkson Disease).

Background: The systemic capillary leak syndrome (SCLS), also known as Clarkson disease, is a very rare condition characterized by recurrent life-threatening episodes of vascular hyperpermeability in the presence of a monoclonal gammopathy. Extended intravenous immunoglobulin (IVIG) treatment is associated with fewer recurrences and improved survival, but the optimal treatment dosage and duration remain unknown.

Objective: We aim to evaluate the safety of IVIG tapering and withdrawal in patients with SCLS.

Antineutrophil Cytoplasm Antibody-Associated Vasculitides Valvular Impairment: Multicenter Retrospective Study and Systematic Review of the Literature.

Objective: While myocardial impairment is a predictor of poor prognosis in antineutrophil cytoplasm antibody (ANCA)-associated vasculitides (AAV), little is known about valvular involvement. This study aims at describing the clinical presentation, management, and outcome of endocarditis associated with AAV.

Methods: We conducted a multicenter retrospective study in centers affiliated with the French Vasculitis Study Group.

Comparative study of granulomatosis with polyangiitis subsets according to ANCA status: data from the French Vasculitis Study Group Registry.

Objective: To investigate whether antineutrophil cytoplasm antibody (ANCA)-negative and myeloperoxidase (MPO)-ANCA-positive granulomatosis with polyangiitis (GPA) differ from proteinase-3 (PR3)-ANCA-positive GPA.

Methods: Diagnostic characteristics and outcomes of newly diagnosed French Vasculitis Study Group Registry patients with ANCA-negative, MPO-ANCA-positive or PR3-ANCA-positive GPA satisfying American College of Rheumatology criteria and/or Chapel Hill Conference Consensus Nomenclature were compared.

Results: Among 727 GPA, 62 (8.

Prognostic Factors and Treatment Efficacy in Spinal Cord Sarcoidosis: An Observational Cohort With Long-term Follow-up.

Background And Objectives: Spinal cord sarcoidosis is a rare manifestation of sarcoidosis with a consequent risk of neurologic sequelae for the patient. We investigated prognostic factors and efficacy of immunosuppressive treatments in a longitudinal cohort.

Methods: We retrospectively studied patients with spinal cord sarcoidosis followed between 1995 and 2021 in 7 centers in France.

Profile of patients with type 2 diabetes and glycated haemoglobin ≥ 10% followed in general practice.

Objective: To determine whether profiles of patients with unbalanced type 2 diabetes (T2DM) and glycated haemoglobin (HbA1c) ≥ 10% could be identified on the basis of socio-demographic, behavioural, clinical, and biological characteristics.

Methods: Retrospective, cross-sectional, factorial analysis study of patients with T2DM treated for at least 1 year, with HbA1c ≥ 10%. Patients were recruited via medical analysis laboratories, France.

Non-anemic iron deficiency: correlations between symptoms and iron status parameters.

Objectives: To register all symptoms reported by non-anemic menstruating women, and examine the links between these symptoms and iron status parameters available including serum ferritin (SF) in primary care.

Subjects And Methods: In this cross-sectional study, we collected clinical and biological data from 780 French menstruating women aged 18-50 years. The data included an anonymous questionnaire (biometric information, physical and cognitive symptoms, reduction in physical performance, current quality of life with SF-36 questionnaire) and seven biological parameters available in primary care.

Splenectomy for primary immune thrombocytopenia revisited in the era of thrombopoietin receptor agonists: New insights for an old treatment.

Although splenectomy is still considered the most effective curative treatment for immune thrombocytopenia (ITP), its use has significantly declined in the last decade, especially since the approval of thrombopoietin receptor agonists (TPO-RAs). The main objective of the study was to determine whether splenectomy was still as effective nowadays, particularly for patients with failure to respond to TPO-RAs. Our secondary objective was to assess, among patients who relapsed after splenectomy, the pattern of response to treatments used before splenectomy.

Localized versus systemic granulomatosis with polyangiitis: data from the French Vasculitis Study Group Registry.

Objective: To describe the main features at diagnosis and evolution over time of patients with localized granulomatosis with polyangiitis (L-GPA) compared with those of systemic GPA (S-GPA).

Methods: EULAR definitions of L-GPA, i.e.

Cardiac sarcoidosis: systematic review of the literature on corticosteroid and immunosuppressive therapies.

Background: Cardiac sarcoidosis (CS) is a life-threatening condition in which clear recommendations are lacking. We aimed to systematically review the literature on cardiac sarcoidosis treated by corticosteroids and/or immunosuppressive agents in order to update the management of CS.

Methods: Using PubMed, Embase and Cochrane Library databases, we found original articles on corticosteroid and standard immunosuppressive therapies for CS that provided at least a fair Scottish Intercollegiate Guidelines Network (SIGN) overall assessment of quality and we analysed the relapse rate, major cardiac adverse events (MACEs) and adverse events.

Significance of eosinophilia in granulomatosis with polyangiitis: data from the French Vasculitis Study Group Registry.

Objective: To describe disease presentation and long-term outcome of granulomatosis with polyangiitis (GPA) patients according to blood eosinophils count (Eos) at vasculitis diagnosis.

Methods: Data from newly diagnosed GPA patients registered in the French Vasculitis Study Group database with available eosinophil count at diagnosis were reviewed. Disease characteristics, rate and type of relapses, and overall survival were analysed according to Eos, categorized as normal (<500/mm3), mild-to-moderate hypereosinophilia (HE) (between 500 and 1500/mm3) and severe HE (>1500/mm3).

Does iron overload in metabolic syndrome affect macrophage profile? A case control study.

Aims: Dysmetabolic iron overload syndrome (DIOS) is common but the clinical relevance of iron overload is not understood. Macrophages are central cells in iron homeostasis and inflammation. We hypothesized that iron overload in DIOS could affect the phenotype of monocytes and impair macrophage gene expression.
