Efficacy and Safety of Dimethyl Fumarate in Patients with Moderate-to-Severe Plaque Psoriasis: Results from a 52-Week Open-Label Phase IV Clinical Trial (DIMESKIN 1).

Introduction: Although dimethyl fumarate (DMF) has been approved since 2017 for treatment of moderate-to-severe plaque psoriasis, limited data on its safety and efficacy are available in clinical practice. The objective was to assess the efficacy and safety of DMF in patients with moderate-to-severe plaque psoriasis through 52 weeks in conditions close to real clinical practice.

Methods: DIMESKIN 1 was a 52-week, open-label, phase IV clinical trial conducted at 36 Spanish sites.

Efficacy of dimethyl fumarate treatment for moderate-to-severe plaque psoriasis: presentation extracts from the 29 EADV virtual congress, 29-31 October 2020.

The 29th EADV Virtual Congress took place between the 29th-31st of October 2020. On October 29th, there was a Session on systemic treatment in which Professors Ulrich Mrowietz and Mar Llamas-Velasco presented the latest research on the efficacy of dimethyl fumarate (DMF) treatment for moderate-to-severe plaque psoriasis (BRIDGE and DIMESKIN 1 studies, respectively). The accepted DMF abstract from Professor Matthias Augustin, on the SKILL study, is also presented here.

Diarrhoea-predominant irritable bowel syndrome: an organic disorder with structural abnormalities in the jejunal epithelial barrier.

Objective: Recently, the authors demonstrated altered gene expression in the jejunal mucosa of diarrhoea-predominant irritable bowel syndrome patients (IBS-D); specifically, the authors showed that genes related to mast cells and the intercellular apical junction complex (AJC) were expressed differently than in healthy subjects. The aim of the authors here was to determine whether these alterations are associated with structural abnormalities in AJC and their relationship with mast cell activation and IBS-D clinical manifestations.

Design: A clinical assessment and a jejunal biopsy were obtained in IBS-D patients (n=45) and healthy subjects (n=30).

Chronological assessment of mast cell-mediated gut dysfunction and mucosal inflammation in a rat model of chronic psychosocial stress.

Life stress and mucosal inflammation may influence symptom onset and severity in certain gastrointestinal disorders, particularly irritable bowel syndrome (IBS), in connection with dysregulated intestinal barrier. However, the mechanism responsible remains unknown. Crowding is a validated animal model reproducing naturalistic psychosocial stress, whose consequences on gut physiology remain unexplored.

Phenotypic and functional characteristics of HIV-specific CD8 T cells and gag sequence variability after autologous dendritic cells based therapeutic vaccine.

A decrease in HIV-1 specific CD8 T-cell responses associated with a partial control of viral replication occurred in 12 HIV-1-infected patients during autologous dendritic cells vaccination. HIV CD8 T cells were detected in 6/10 patients during immunizations, increasing after HAART discontinuation in 3 of them. Tet+ CD8 cells mainly had an effector phenotype (CD45RA-/+ CCR7- and CD28- and Perf+/-) and maintained IFN-gamma release throughout follow-up.

Therapeutic immunization with dendritic cells loaded with heat-inactivated autologous HIV-1 in patients with chronic HIV-1 infection.

Therapeutic immunization with autologous monocyte-derived dendritic cells (DCs) loaded with heat-inactivated autologous human immunodeficiency virus type 1 (HIV-1) in 12 patients with chronic HIV-1 infection who were receiving highly active antiretroviral therapy (HAART) was feasible, safe, and well tolerated. Virus was obtained during an initial interruption of HAART (hereafter, "stop 1") so that DCs could be pulsed. After immunization and a second interruption of HAART (hereafter, "stop 2"), set-point plasma viral load (PVL; 24 weeks after stop 2) decreased > or =0.

Similar HIV-1 evolution and immunological responses at 10 years despite several therapeutic strategies and host HLA Types.

Two sexual partners infected with related HIV-1 viruses and enrolled in different therapeutic strategies including structured treatment interruptions (STI) provided us an opportunity to compare long term (10 years) viral genetic evolution for closely related isolates in different hosts. HLA loci were molecularly typed and different genetic markers were studied. The viral genetic evolution was studied by sequencing pol and env genes.
