Background: Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021.

Role of microRNAs in immunoregulatory functions of epithelial cells.

BMC Immunol

December 2024

Immunogenetics Research Center, Faculty of Medicine, Mazandaran University of Medical Sciences, Sari, Iran.

Epithelial cells (ECs) provide the first line of defense against microbial threats and environmental challenges. They participate in the host's immune responses via the expression and secretion of various immune-related molecules such as cytokines and chemokines, as well as interaction with immune cells. A growing body of evidence suggests that the dysregulated function of ECs can be involved in the pathophysiology of a broad range of infectious, autoimmune, and inflammatory diseases, including inflammatory bowel disease (IBD), asthma, multiple sclerosis, and rheumatoid arthritis.

SARS-CoV-2 ORF8 drives osteoclastogenesis in preexisting immune-mediated inflammatory diseases.

JCI Insight

December 2024

Infection Biology Program, Global Center for Pathogen Research and Human Health, Lerner Research Institute, Cleveland Clinic, Cleveland, Ohio, USA.

Patients with immune-mediated inflammatory diseases (IMIDs) like rheumatoid arthritis (RA) are at higher risk for severe COVID-19 and long-term complications in bone health. Emerging clinical evidence demonstrated that SARS-CoV-2 infection reduces bone turnover and promotes bone loss, but the mechanism underlying worsened bone health remains elusive. This study sought to identify specific immune mediators that exacerbated preexisting IMIDs after SARS-CoV-2 exposure.

Investigating the link between Helicobacter pylori infection and psoriatic disease: an immunological study.

Immunol Res

December 2024

Department of Rheumatology and Clinical Immunology, Faculty of Medicine, School of Health Sciences, University of Thessaly, Larissa, 41110, Greece.

Helicobacter pylori (Hp) has been postulated as an infectious trigger of psoriatic disease, namely psoriasis (Ps) and psoriatic arthritis (PsA), but meticulous antibody (ab) reactivity against all dominant and subdominant Hp antigens in demographically matched PsA and Ps patients and healthy controls has not been performed so far. IgG anti-Hp ab testing was performed by combining immunoblotting and line assays in 263 serum samples from 89 patients with PsA, 114 patients with Ps, and 60 demographically matched healthy controls (HCs). Anti-Hp positivity did not differ between PsA, Ps, and HCs (P > 0.

Arthritis Res Ther

December 2024

Department of Clinical Laboratory, The First Affiliated Hospital, Jiangxi Medical College, Nanchang University, Nanchang, Jiangxi, 330006, China.

Background: Neutropenia is more common in patients with systemic lupus erythematosus (SLE) and is a major cause of life-threatening infections. The increased apoptosis of neutrophils is likely to be an essential cause of neutropenia in SLE. However, the detailed mechanisms of increased neutrophil apoptosis in SLE remain unknown.

Background: Gout is one of the oldest known diseases and the most common form of inflammatory arthritis. The established risk factors for gout include hyperuricemia, chronic renal disease, genetic, alcohol consumption, dietary factors, diuretic use, hypertension, obesity, and metabolic syndrome. Patients with gout have an increased risk of all-cause mortality, particularly from cardiovascular disease, cancer, and infectious diseases.

Resident synovial macrophages (RSMs) are anti-inflammatory, self-renewing macrophages that provide physical immune sequestration of the joint space from the peripheral immune system. Increased permeability of this structure is associated with peripheral immune cells in the synovial fluid (SF). Direct measures of synovial barrier integrity are possible with tissue histology, but after barrier breakdown, if these cells perpetuate or initiate chronic inflammation in SF remains unknown.

The alphavirus chikungunya virus (CHIKV) is a serious human pathogen that can cause large-scale epidemics characterized by fever and joint pain and often resulting in chronic arthritis. Infection by alphaviruses including CHIKV and the closely related Semliki Forest virus (SFV) can induce the formation of filopodia-like intercellular long extensions (ILEs). ILEs emanate from an infected cell, stably attach to a neighboring cell, and mediate cell-to-cell viral transmission that is resistant to neutralizing antibodies.

Background: Septic arthritis (SA) of the hip joint is a serious infection that can result in irreversible complications. Distinguishing septic arthritis from transient synovitis, the most common cause of hip pain in children, is crucial for preventing severe outcomes. Existing research has primarily focused on identifying clinical signs and laboratory findings that indicate high-risk patients who may need invasive diagnostic procedures; however, results have been inconsistent.

To find a distinct non-coding RNA characteristic for idiopathic uveitis in the pediatric population. To explore the autoimmune-related miRNA expression profile in pediatric patients with idiopathic uveitis (IU) and juvenile idiopathic arthritis-associated uveitis (JIA-AU) and find a common molecular background for idiopathic uveitis and other autoimmune diseases. The expression levels of miRNAs were analyzed by quantitative real-time PCR using serum samples from patients with idiopathic uveitis (n = 8), juvenile idiopathic arthritis-associated uveitis (n = 7), and healthy controls.

Minocycline-induced lupus.

BMJ Case Rep

December 2024

Division of Infectious Diseases, Department of Internal Medicine, University of Iowa, Iowa City, Iowa, USA.

Antibiotics are indicated for inappropriately prolonged durations not only for infectious diseases but also for non-infectious dermatologic conditions such as acne vulgaris, but inappropriate use is not uncommon. Inappropriate antibiotic prescription can contribute to the emergence of multidrug-resistant organisms, patient harm such as adverse drug events and increased healthcare costs. We experienced a case involving a late adolescent with acne vulgaris who had been treated with minocycline for more than 2 years, leading to the development of drug-induced lupus, attributed to minocycline.

Department of Epidemiology and Biostatistics, Temple University Philadelphia, PA, USA; Water, Health and Applied Microbiology Lab, Department of Pathobiology, University of Guelph, Guelph, ON, Canada. Electronic address:

Background: Campylobacter, nontyphoidal Salmonella, Cryptosporidium, and Giardia cause an estimated 1 million cases of domestically acquired waterborne diseases annually in the United States. Acute symptoms can include diarrhea and vomiting; however, these illnesses can result in longer term complications such as reactive arthritis, Guillan Barré syndrome and death, particularly in immunocompromised individuals. Precipitation and drought can plausibly increase the risk of enteric infections, but consensus in the literature is lacking.

December 2024

School of Basic Medical Sciences, Lanzhou University, Lanzhou, Gansu, China.

Autophagy is an essential intracellular degradation system responsible for delivering cytoplasmic components to lysosomes. Within this intricate process, optineurin (OPTN), an autophagy receptor, has attracted extensive attention due to its multifaceted roles in the autophagy process. OPTN is regulated by various posttranslational modifications and actively participates in numerous signaling pathways and cellular processes.
