Background: It is unknown which maintenance therapy is the most effective option for patients admitted for an acute severe ulcerative colitis (ASUC) episode responding to intravenous steroids.

Methods: We conducted a multicentre, parallel-group, open-label randomised controlled trial among 23 French centres in thiopurine and biologics-naïve adults admitted for ASUC responding to intravenous steroids. Eligible patients were randomly assigned to receive infliximab (IFX) and azathioprine (AZA) with a 7-day steroid tapering scheme (IFX+AZA arm) or AZA and conventional standardised steroid tapering regimen (AZA arm).

Background: Nutrition is largely affected in bipolar disorder (BD), however, there is a lack of understanding on the relationship between dietary categories, BD, and the prevalence of metabolic syndrome. The objective of this study is to examine dietary trends in BD and it is hypothesized that diets with increased consumption of seafood and high-fiber carbohydrates will be correlated to improved patient outcomes, and a lower frequency of metabolic syndrome.

Methods: This retrospective cohort study includes two French cohorts.

Mitochondrial Biomarkers and Metabolic Syndrome in Bipolar Disorder.

Psychiatry Res

September 2024

Department of Pharmacology and Toxicology, Temerty Faculty of Medicine, University of Toronto, Toronto, ON, Canada; Mitochondrial Innovation Initiative, MITO2i, Toronto, ON, Canada; Department of Psychiatry, University of Toronto, Toronto, ON, Canada.

Article Synopsis
  • This study investigates the link between mitochondrial blood biomarkers, specifically lactate and circulating cell-free mitochondrial DNA, and markers of metabolic syndrome in bipolar disorder patients, hypothesizing that lactate levels would be higher in those with metabolic syndrome.
  • The research involved a large cohort of 837 stable bipolar disorder patients and 237 others for validation, revealing that higher lactate levels correlated significantly with factors like triglycerides and blood pressure, indicating a strong association with metabolic syndrome.
  • The findings suggest that while lactate is a key biomarker related to metabolic syndrome in bipolar patients, circulating mitochondrial DNA levels do not show this same correlation, highlighting the potential for personalized treatment strategies based on these metabolite profiles.

Rev Neurol (Paris)

December 2024

Department of Neurology and Functional Neuroscience and Pathology Laboratory, Jules-Verne University of Picardy, Amiens University Hospital, CHU de Amiens-Picardie, 80054 Amiens, France.

Background: The association between the pattern of cortical thickness (CT) and executive dysfunction (ED) in mild cognitive impairment (MCI) and subjective cognitive complaints (SCC) is still poorly understood. We aimed to investigate the association between CT and ED in a large French cohort (MEMENTO) of 2323 participants with MCI or SCC.

Methods: All participants with available CT and executive function data (verbal fluency and Trail Making Test [TMT]) were selected (n=1924).

Electronic address:

FMS-related tyrosine kinase 3 ligand (FLT3L), encoded by FLT3LG, is a hematopoietic factor essential for the development of natural killer (NK) cells, B cells, and dendritic cells (DCs) in mice. We describe three humans homozygous for a loss-of-function FLT3LG variant with a history of various recurrent infections, including severe cutaneous warts. The patients' bone marrow (BM) was hypoplastic, with low levels of hematopoietic progenitors, particularly myeloid and B cell precursors.

Article Synopsis
  • Researchers examined the effects of combining prazosin (α1b blocker) and cyproheptadine (5HT2A blocker) on alcohol consumption in individuals with Alcohol Use Disorder (AUD).
  • The study involved 154 participants in France, who were divided into three groups for a 3-month trial: low-dose, high-dose, and placebo.
  • Results indicated a significant reduction in total alcohol consumption (TAC) for both the low and high-dose groups compared to the placebo, suggesting that this combination therapy is effective and safe for decreasing alcohol intake.

The complex interaction between viruses and fungi has profound implications, especially given the significant impact of these microorganisms on human health. While well-known examples such as HIV, influenza, and SARS-CoV-2 are recognized as risk factors for invasive fungal diseases, the relationship between viruses and fungi remains largely underexplored outside of these cases. Fungi and viruses can engage in symbiotic or synergistic interactions.

Allergic fungal rhinosinusitis and eosinophilic mucin chronic rhinosinusitis: Differential diagnostic criteria. A two-center comparative study following STROBE methodology.

Objectives: Allergic fungal rhinosinusitis (AFRS) and eosinophilic mucin chronic rhinosinusitis (EMRS) are two forms of chronic sinusitis distinguished by the presence (AFRS) or absence (EMRS) of fungal elements in sinus mucin. Detection of the fungal elements, however, is complex and it is difficult to say whether EMRS is in fact an entity distinct from AFRS. The aim of the present study, based on a retrospective series of AFRS and EMRS, was to identify the specific clinical and radiological elements distinguishing between the two.

Investigation of CryptoPS LFA-positive sera in patients at risk of cryptococcosis.

Med Mycol

October 2022

Laboratoire de parasitologie-mycologie, AP-HP, Hôpital Saint-Louis, F-75010 Paris, France.

Article Synopsis
  • Cryptococcal antigen (CrAg) is a marker found in the fluids of patients with cryptococcal infections, and various testing methods like CALAS and LFA are used to detect it, including commercial kits like CryptoPS and CrAg LFA.
  • In a 3-year study involving 43 serum samples, the CryptoPS test showed a high rate of false positives, indicating that patients without cryptococcal infections often tested positive, suggesting the presence of interfering substances in the serum.
  • A simple pretreatment method (incubation and centrifugation) was effective in reducing false positives, though it slightly affected the sensitivity of the test for some patients with actual cryptococcal disease.

  • The strain from the two patients (P0 and P1) was traced back to the Middle East, with whole-genome sequencing confirming high genetic similarity, highlighting the effectiveness of genomic analysis in tracking infections.
  • Notably, P1 showed signs of colonization 41 to 61 days after possible exposure to P0, despite three negative screenings, suggesting that current screening methods may need revisions to better detect long-term incubations of C. auris.
