Dengue remains a leading cause of child mortality in Indonesia. Identifying reliable biomarkers to predict disease severity is essential for early intervention. Macrophage Migration Inhibitory Factor (MIF) is a pro-inflammatory cytokine involved in the pathogenesis of dengue. This study aimed to assess the relationship between MIF levels and dengue severity in children, and to compare  the predictive value of MIF levels with C-Reactive Protein (CRP) and serum albumin levels. A cross-sectional study was conducted on 104 pediatric dengue patients hospitalized at Saiful Anwar General Hospital. Serum levels of MIF (ELISA), CRP, and albumin were measured upon admission. Patients were categorized into four severity grades (Grade 1–4) and also stratified into shock and non-shock groups. Statistical analyses included ANOVA, correlation analysis, and receiver operating characteristic (ROC) curve evaluation. MIF levels showed a significant stepwise increase with disease severity and were significantly higher in patients with shock (p < 0.001). CRP levels were also elevated in severe dengue, but the correlation with severity was moderate (r = 0.61, p < 0.05). In contrast, serum albumin levels were inversely associated with severity (r = –0.67, p < 0.05), with lower values observed in the shock group. ROC analysis demonstrated that MIF had the highest predictive accuracy for shock (AUC = 0.94), compared to CRP (AUC = 0.78) and albumin (AUC = 0.81). MIF is a robust biomarker for predicting dengue severity and shock in children, outperforming CRP and albumin in diagnostic performance. The integration of MIF with conventional markers may improve early risk stratification and clinical decision-making in pediatric dengue.

Periodontitis is a common and persistent inflammatory disease resulting from a sophisticated relationship between oral bacteria and the body's immune system. Toll-like receptors (TLRs) act as crucial sensors within the immune response, playing a fundamental role in the disease's initiation and progression. This review examines periodontitis, highlighting the limited understanding of TLR activation mechanisms and the therapeutic potential of TLR inhibitors. The discussion begins with a definition of TLRs, outlining their characteristics, types, distribution, and activation mechanisms. It then details the manifestation of TLRs in periodontitis, including alterations during inflammation and their correlation with disease severity. TLR activity is influenced not only by microbial stimuli but also by epigenetic factors and miRNAs, which mediate gene expression changes linked to inflammation. Various miRNAs have been shown to regulate TLR signaling pathways, thereby modulating the inflammatory response in periodontal tissues. Additionally, epigenetic modifications further complicate the landscape of immune regulation in periodontitis, affecting TLR expression and function. This interplay between TLRs, miRNAs, and epigenetic changes underscores the systemic implications of periodontal disease, contributing to broader health issues. Consequently, the review explores innovative strategies to modulate TLR signaling and discusses future challenges in TLR research in relation to periodontitis treatment. In summary, a more profound understanding of TLR-driven immune responses, along with the regulatory roles of miRNAs and epigenetic factors, is essential for developing targeted therapies and advancing treatment options for periodontitis.

To examine the immunopathological mechanisms underlying heart failure with preserved ejection fraction (HFpEF) in elderly patients and evaluate exercise training as an immunomodulatory intervention for managing disease complications. A narrative literature review was conducted using PubMed, Embase, and Cochrane Library databases (2010–2023), focusing on immune dysfunction, aging, and exercise interventions in HFpEF. HFpEF pathophysiology in elderly patients involves complex interactions between innate and adaptive immunity, characterized by elevated pro-inflammatory cytokines, NLRP3 inflammasome activation, and immune cell dysfunction. Major complications—frailty syndrome, sarcopenia, and malnutrition—share common inflammatory pathways that perpetuate disease progression. Exercise training fundamentally alters this inflammatory profile through multiple mechanisms: suppressing pro-inflammatory cytokine production (TNF-α, IL-1β, IL-6), promoting anti-inflammatory immune cell phenotypes, and enhancing tissue regenerative capacity. Unlike pharmacological interventions targeting single pathways, exercise exerts pleiotropic effects across the immune-inflammatory network, simultaneously addressing cardiac dysfunction and systemic complications. Structured exercise programs effectively interrupt inflammatory cascades, improve functional capacity, and enhance quality of life in elderly HFpEF patients. Exercise training represents a cornerstone intervention that directly targets the fundamental immunopathology of HFpEF. Implementation of specialized exercise-based cardiac rehabilitation programs tailored to elderly patients is urgently needed to optimize clinical outcomes in this growing population.
