Regulatory T and B cells in pediatric Henoch-Schönlein purpura: friends or foes?

Background And Objectives: Henoch-Schönlein purpura (HSP) is the most common immunoglobulin A-mediated systemic vasculitis in childhood. We studied immune dysregulation in HSP by analyzing regulatory T (Treg), T helper 3 (Th3), and regulatory B cell (Breg) subpopulations that might intervene in immune activation, IgA production, and HSP clinical manifestations.

Methods: This prospective study included 3 groups of children: 30 HSP on acute phase, 30 HSP on remission, and 40 healthy controls (HCs) matched on age.

Hybrid closed Loop improved glucose control compared to sensor-augmented pumps in outpatients with type 1 diabetes in real-life conditions with telehealth monitoring.

Objectives: The study aims at evaluating glucose metrics and HbA1C values after pump initiation in outpatient settings.

Research Design And Methods: This single center observational study enrolled 121 subjects with type 1 diabetes between September 2020 and May 2021 initiating sensor-augmented pump therapy with stand-alone CGM (n = 26) or pump users who only changed their device (n = 51), with predictive low glucose management (n = 8) or with Hybrid Closed Loop using Medtronic 780G (n = 36) systems. Changes in HbA1C levels and glucose metrics were analyzed after 3 months.

[The clinical and pathogenic significance of the chronic specific infection in the gastroenterology].

As a result of the integrative evaluation of clinical and laboratory results of 610 patients with pathology of the digestive system, which was accompanied with the chronic specific infection (CSI) such as VHA, VHE, VHB, VHC, VHD, GB, F, TTV, SEN; types I and II herpes virus, cytomegalovirus, toxoplasmosis. The conception of the systemic polyglandulopathy was formulated. The authors have analyzed some pathogenic mechanisms and clinical pecularities of the chronic specific infection in patients with the diseases of the digestive system and the principles of the diagnosis and complex treatment were proposed.

[The clinical significance of phasic duodenal intubation and ultrasonic monitoring of the gallbladder in healthy subjects].

Overall twelve essentially healthy subjects were evaluated for the tone and contractile function of the gallbladder according to phases of interdigestive motility of duodenum as were for effects on these functions of phase-by-phase administration of 30 ml of 33% solution of magnesium sulphate. The gallbladder in healthy individuals was found out to function according to phases of duodenal interdigestive motility and be ready to evacuate bile during phase II. Prior diagnostic techniques did not take advantage of interdigestive phase of duodenal and gallbladder motility during which phase a standard stimulating agent was routinely employed.
