Article Abstract

Objectives: Gout (GT) belongs to a group of diseases caused by a purine metabolic disorder. GT is an inflammatory disease caused by the local deposition of uric acid in joints or adjacent tissues. The mechanism of GT is not fully explained, especially the involvement of an immune system. The objective of this study was to investigate the change in peripheral CD4T subsets in acute and chronic GT patients.

Methods: A total of 205 patients with acute and chronic GT and 87 healthy controls (HCs) were enrolled. The medical history improvement, clinical indicators, immune function, and peripheral CD4T-lymphocyte detected by modified flow cytometry were collected in all subjects.

Results: Compared with healthy controls, acute and chronic GT patients remarkably increased the absolute counts of T helper type 1 (Th1) cells (P < 0.05) and decreased the absolute number of Treg cells without significant difference (P > 0.05). In addition, the absolute number and percentage of Th1 cells and Th1/T helper type 2 (Th2) ratio increased significantly, and the ratio of Th2 cells decreased in patients with chronic GT compared to patients with acute GT (P < 0.05). The results of Spearman correlation analysis showed a notably negative correlation between the level of CRP and the absolute counts of peripheral Th1 and Th17 cells in patients with GT, while the levels of CD4T sunsets had no significant correlation with ESR and uric acid. The course of the disease, the absolute number of Th1 cells, the percentage of Th1 cells and the ratio of Th1/Th2 cells were significantly associated with the progression of the disease, and the course of the disease was an independent risk factor for patients with chronic GT.

Conclusion: The balance of Th1 and Th2 were involved throughout the whole stages of GT, Th17 cells then become involved in the disease process as the disease progresses.

Background: Post-viral syndromes, including long- and post-COVID, often lead to persistent symptoms such as fatigue and dyspnoea, affecting patients' daily lives and ability to work. The COVI-Care M-V trial examines whether interprofessional, patient-centred teleconsultations, initiated by general practitioners in cooperation with specialists, can help reduce symptom burden and improve care for patients.

Methods: To evaluate the effectiveness of the intervention under routine care conditions, a cluster-randomised controlled trial is being conducted.

Background: Kidney involvement in pediatric sarcoidosis is rare and often underrecognized, leading to diagnostic delays and treatment challenges. We report six patients with renal sarcoidosis to highlight their diverse presentations and outcomes and challenges in management.

Methods: Medical records of patients diagnosed with renal sarcoidosis during 2020-24 were reviewed.

Urinary tract infections (UTIs) are among the most common bacterial infections and are increasingly complicated by multidrug resistance (MDR). While Escherichia coli is frequently implicated, the contribution of broader microbial communities remains less understood. Here, we integrate metatranscriptomic sequencing with genome-scale metabolic modeling to characterize active metabolic functions of patient-specific urinary microbiomes during acute UTI.

Introduction: The vulnerability of white matter (WM) in acute and chronic moderate-severe traumatic brain injury (TBI) has been established. In concussion syndromes, including preclinical rodent models, lacking are comprehensive longitudinal studies spanning the mouse lifespan. We previously reported early WM modifications using clinically relevant neuroimaging and histological measures in a model of juvenile concussion at one month post injury (mpi) who then exhibited cognitive deficits at 12mpi.

Background: Mycobacterium simiae is a slow-growing environmental nontuberculous mycobacterium (NTM), commonly isolated from soil and water. M. simiae is not known to transmit zoonotically or via human-to-human contact; infection is presumed to occur through direct environmental exposure.
