We report the case of a 75-year-old woman with a 15-year history of inappetance resulting in weight loss of approximately 40 kg. On physical examination, the skin of the lower extremities was markedly hyperpigmented with a brown-greyish hue. In addition, the skin of the legs was infiltrated, erythematous, riddled with erosions and necrotic ulcers. Clinical and laboratory evaluation revealed sicca syndrome, a pronounced polyclonal hypergammaglobulinemia (60 g/l), high levels of antinuclear, anti-SSA and anti-SSB antibodies. Histological examination of involved skin demonstrated a leukocytoclastic vasculitis.

Impact of dysregulated microbiota-derived C18 polyunsaturated fatty acid metabolites on arthritis severity in mice with collagen-induced arthritis.
Front Immunol
January 2025
Department of Rheumatology and Clinical Immunology, Kobe University Graduate School of Medicine, Kobe, Japan.
Objective: We aimed to evaluate microbiome and microbiota-derived C18 dietary polyunsaturated fatty acids (PUFAs), such as conjugated linoleic acid (CLA), and to investigate their differences that correlate with arthritis severity in collagen-induced arthritis (CIA) mice.
Methods: On day 84 after induction, during the chronic phase of arthritis, cecal samples were analyzed using 16S rRNA sequencing, and plasma and cecal digesta were evaluated using liquid chromatography-tandem mass spectrometry. Differences in microbial composition between 10 control (Ctrl) and 29 CIA mice or between the mild and severe subgroups based on arthritis scores were identified.
Clinical and Laboratory Parameters of Metabolic Syndrome in Chronic Spontaneous Urticaria: A Cross-Sectional Study.
Indian Dermatol Online J
December 2024
Department of Dermatology, Venereology, and Leprosy, GSL Medical College and General Hospital, Rajahmahendravaram, Andhra Pradesh, India.
Background: Chronic spontaneous urticaria (CSU) appears to share some pathomechanisms with metabolic syndrome (MS), such as proinflammatory state, increased oxidative stress, changes in adipokine profile, and coagulation system activation.
Aim And Objectives: To evaluate clinical and laboratory parameters of MS in CSU patients and to assess relationship of MS with duration and severity of CSU, Ig-E, thyroid-stimulating hormone (TSH), C-reactive protein (CRP), and autologous serum skin test (ASST).
Materials And Methods: A hospital-based cross-sectional study was conducted on 131 CSU cases and 131 controls who were age- and sex-matched.
Clinical outcomes of COVID-19 infection in liver transplant recipients based on vaccination status.
Front Transplant
January 2025
Section of Transplant Surgery, Washington University School of Medicine, St. Louis, MO, United States.
Background: COVID-19 disease burden has been mitigated by vaccination; however, concerns persist regarding weakened immune responses in liver transplant (LT) recipients. This study investigates COVID-19 outcomes in LT recipients based on vaccination status.
Methods: This single-center retrospective study identified LT recipients with PCR-confirmed COVID-19 infection from 03/01/2020 to 07/31/2023.
Acupoint catgut embedding alleviates experimental autoimmune encephalomyelitis by modulating neuroinflammation and potentially inhibiting glia activation through JNK and ERK pathways.
Front Neurosci
January 2025
Department of Neurology, The Third Affiliated Hospital of Sun Yat-Sen University, Guangzhou, China.
Background: Acupoint catgut embedding (ACE) is a traditional Chinese medicine technique commonly used for managing various disorders, including chronic inflammatory pain and allergic asthma. Despite its growing use, the neuroimmunological mechanisms underlying ACE treatment effects remain unclear.
Methods: This study investigated the roles and potential mechanisms of the effects of ACE in treating experimental autoimmune encephalomyelitis (EAE), a frequently used animal model of autoimmune neuroinflammation.
Post-burns persistent inflammation leads to kidney PANoptosis with Caspases pathway activation.
Heliyon
January 2025
Division of Nephrology, University of Rochester Medical Center, Rochester, NY, USA.
Background: There is higher prevalence of chronic kidney disease (CKD) in burn patients after hospital discharge; however, the cause remains unclear. This study aimed to investigate the lasting impacts of severe burns on the kidneys and to explore potential treatments.
Methods: The study examined the effects of burning on healthy mice and adenine-induced CKD mice.
