Investigations into fruit and vegetable processing residues (FVPRs) offer huge opportunities to discover novel therapeutics against many diseases. In this study, detailed investigation of Garcinia mangostana fruit peel extract led to the isolation and identification of ten known compounds (1-10). Further, a new series of α-mangostin derived sulphonyl piperzines, aryl alkynes and 1,2,3-triazole derivatives were synthesized using Huisgen 1,3-dipolar cyclo-addition reaction ("click" chemistry).

Heart involvement is one of the leading causes of death among patients with SSc. In this study, we aimed to assess the effect of various vasodilator treatments.

Gemcitabine-induced thrombotic microangiopathy (G-TMA) can clinically and biologically present as atypical hemolytic uremic syndrome, with activation of the complement pathway asking the question of the use of eculizumab. We describe here the case of a patient suffering from metastatic cholangiocarcinoma treated by gemcitabine for 4 years leading to the remission of the underlying neoplasia.

Methods: This was a national, multicentre, prospective, non-interventional cohort study (). Among the 35 patients with histologically proven orbital inflammation who had previously been studied for their IgG4 immunostaining status, we selected those with a negative IgG4 status (ie, pIOIS) who received corticosteroids as single first-line treatment.
Background: Sarcoidosis is an idiopathic systemic granulomatosis whose evolution is self-limiting in most cases. However, it can progress to organ damage that menaces the vital or functional prognosis of patients. Sarcoidosis itself, but also its comorbidities, can pose a threat to the patient, require rapid initiation of treatment, and justify emergency hospitalization.

Methods: A multicentre retrospective study was conducted of a cohort of scleroderma patients who had undergone muscle biopsy. The biopsies were reviewed in a coordinated manner to classify patients based on histological findings.

Objective: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) primarily affects small vessels. Large-vessel involvement (LVI) is rare. We aimed to describe the characteristics of LVI, to identify associated risk factors, and to describe its therapeutic management.
View Article and Find Full Text PDFObjective: Although airway disease associated with Sjögren's disease (Sjo-AD) is common, it is poorly studied compared with interstitial lung disease (ILD). In this study, we aimed to assess factors associated with Sjo-AD, the characteristics and prognosis of this manifestation.
Methods: We performed a retrospective multicentric study involving nine centres.
Objective: Describe the characteristics of patients presenting with TTS during the course of a broad spectrum of systemic diseases, in comparison to classic TTS.
Methods: French multicenter retrospective case-control study completed by a literature review.
Results: 19 new cases were included in the study.

Objectives: Heart involvement is one of the leading causes of death in systemic sclerosis (SSc). The prevalence of SSc-related cardiac involvement is poorly known. Our objective was to investigate the prevalence and prognosis burden of different heart diseases in a nationwide cohort of patients with SSc.
View Article and Find Full Text PDFObjective: To investigate the association of air pollution exposure with the severity of interstitial lung disease (ILD) at diagnosis and ILD progression among patients with systemic sclerosis (SSc)-associated ILD.
Methods: We conducted a retrospective two-center study of patients with SSc-associated ILD diagnosed between 2006 and 2019. Exposure to the air pollutants particulate matter of up to 10 and 2.
Background: Amoebiasis is an intestinal and tissue parasitic infection caused by the protozoan Entamoeba histolytica. Despite significant medical importance and worldwide dispersion, little is known about the epidemiology and distinct geographical distribution of various clinical forms of amoebiasis in the world. In this study, we present an amoebiasis case series referred to Avicenne Hospital (Bobigny, France) from 2010 to 2022 followed by an overview of the released literature to explore diverse clinico-pathology of amoebiasis and to update the actual epidemiological situation of this parasitosis worldwide.

The acquired von Willebrand syndrome is a rare bleeding disorder. This case underlines the importance of maintaining the corticosteroid therapy in order to prevent the reappearance of autoantibodies and the recurrence of this syndrome.

We compared the efficacy of glucocorticoid and rituximab (RTX) or CYC induction therapy for severe AAV-related glomerulonephritis and evaluated the potential benefit of plasma exchange (PE) as adjunct therapy to CYC.
Methods: This retrospective, multicentre study included AAV patients with severe renal active disease (serum creatinine level ≥350 µmol/l and/or estimated glomerular filtration ratio ≤15 ml/min/1.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, which caused the coronavirus disease 2019 (COVID-19) pandemic as declared by the World Health Organization, has created havoc worldwide. The highly transmissible infection can be contained only by accurate diagnosis, quarantining, and exercising social distancing. Therefore, quick and massive deployment of SARS-CoV-2 testing plays a crucial role in the identification and isolation of infected patients.

A new case is described of a patient with multiple excavated subpleural pulmonary nodules, a rare localization of secondary syphilis. Despite the numerous pulmonary samples analysed in the literature, is rarely visualised directly on bronchial fibroscopy or biopsy.

Methods: All consecutive patients managed for new-onset OID between 2011 and 2018 in a tertiary referral center, who underwent FDG-PET/CT as part of the etiological diagnostic workup were evaluated. To quantify the incremental value of FDG-PET/CT over standard diagnostic workup, the Net Reclassification Index (NRI) and Integrated Discrimination Index (IDI) were used.
Recent evidence showed greater efficacy of tocilizumab (TCZ) in the subgroups of COVID-19 patients who presented with symptoms for less than 7 days and in those only receiving oxygen. We retrospectively analyzed a compassionate use cohort to determine the best timing for TCZ injection. We showed no association between the timing of injection after symptom onset and the efficacy of TCZ on mortality.
View Article and Find Full Text PDFBackground: Reduced mortality at 28 days in patients treated with corticosteroids was demonstrated, but this result was not confirmed by certain large epidemiological studies. Our aim was to determine whether corticosteroids improve the outcomes of our patients hospitalized with COVID-19 pneumonia.
Methods: Our retrospective, single centre cohort study included consecutive patients hospitalized for moderate to severe COVID-19 pneumonia between March 15 and April 15 2020.
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a highly transmittable and pathogenic human coronavirus that caused a pandemic situation of acute respiratory syndrome, called COVID-19, which has posed a significant threat to global health security. The aim of the present study is to computationally design an effective peptide-based multi-epitope vaccine (MEV) against SARS-CoV-2. The overall model quality of the vaccine candidate, immunogenicity, allergenicity, and physiochemical analysis have been conducted and validated.

The clinical presentations are varied, most of the time, with a relatively typical picture of mediastinopulmonary involvement. More rarely, isolated granulomatous locations from various organs are described, leading to difficulties in diagnosis.
