E4BP4 restrains effector-memory CD8+ T cell responses in systemic lupus erythematosus.
Increasing evidence shows that CD8+ T cells are the pathogenic mediators of tissue injury in systemic lupus erythematosus (SLE), sustaining the chronic inflammation through the accumulation of long-lived cytotoxic memory populations. However, the transcriptional mechanisms that prevent the aberrant…
Evaluation of clinicopathological features of renal biopsies in non-lupus rheumatic diseases: a university hospital experience.
Renal involvement is a common condition in rheumatologic diseases. The aim of this study was to evaluate the clinical presentations and histopathological results in patients diagnosed with non-lupus rheumatic diseases who underwent renal biopsy. The records of 900 renal biopsies performed at our hos…
HSP27 in autoimmune diseases: Context-dependent regulation and clinical potential.
Heat shock protein 27 (HSP27) is a crucial member of the small heat shock protein family with a molecular weight of approximately 27 kDa, playing key roles in cellular stress response, protein homeostasis, and cell survival regulation. Recent studies have revealed that HSP27 plays a complex dual rol…
Characterizing cutaneous manifestations of systemic autoimmune rheumatologic diseases in Filipino skin.
Cutaneous findings provide important clues to systemic autoimmune rheumatologic diseases (SARDs), but presentation varies across skin types and may be underrecognized in patients of color. In the Philippines, diagnostic challenges are amplified by limited specialists and a lack of pigmented-skin lea…
Association between osteoporosis and arthritis: Results from the NHANES and Mendelian randomization study.
This study seeks to investigate associations of osteoporosis (OP) with arthritis and to assess causality using Mendelian randomization (MR). Firstly, an observational study was conducted using the National Health and Nutrition Examination Survey (NHANES). The relationship between OP and arthritis wa…
Pampiniform venous plexus thrombosis in a 37 years-old male patient with severe thrombocytosis: a multifactorial aetiology.
Atypical thrombosis occurs in unconventional anatomical sites such as splanchnic, renal, gonadal, and cerebral venous vessels [1] . Genetic factors, as inherited thrombophilia could increase the risk of atypical thrombosis. Likewise, acquired disease, as cancer, autoimmune diseases (e.g. systemic lu…
Pearls & Oy-sters: Bilateral Neuropathic Facial Pain With Autonomic Features and Neurovascular Contact.
Trigeminal neuralgia (TN) is an uncommon disorder, with an annual prevalence of 0.03%-0.3% in North America. It is typically unilateral, most commonly involving the V2 and V3 distributions and may be accompanied by mild autonomic features. We report a 35-year-old woman who developed severe right mor…
Clinical characteristics of patients with primary antiphospholipid syndrome and "single" antiphospholipid antibody: Retrospective results from the APS ACTION clinical database and repository ("registry").
ObjectiveWhile triple antiphospholipid antibody (aPL) positivity is associated with a higher risk of thrombosis, the clinical significance of single aPL positivity remains unclear. This study aimed to assess the prevalence, clinical characteristics, and cardiovascular disease (CVD) risk profile of p…
