Abstract
The anemia of inflammation (AI) is characterized by the presence of inflammation and abnormal elevation of hepcidin. Accumulating evidence has proved that Rocaglamide (RocA) was involved in inflammation regulation. Nevertheless, the role of RocA in AI, especially in iron metabolism, has not been investigated, and its underlying mechanism remains elusive. Here, we demonstrated that RocA dramatically suppressed the elevation of hepcidin and ferritin in LPS-treated mice cell line RAW264.7 and peritoneal macrophages. In vivo study showed that RocA can restrain the depletion of serum iron (SI) and transferrin (Tf) saturation caused by LPS. Further investigation showed that RocA suppressed the upregulation of hepcidin mRNA and downregulation of Fpn1 protein expression in the spleen and liver of LPS-treated mice. Mechanistically, this effect was attributed to RocA's ability to inhibit the IL-6/STAT3 pathway, resulting in the suppression of hepcidin mRNA and subsequent increase in Fpn1 and TfR1 expression in LPS-treated macrophages. Moreover, RocA inhibited the elevation of the cellular labile iron pool (LIP) and reactive oxygen species (ROS) induced by LPS in RAW264.7 cells. These findings reveal a pivotal mechanism underlying the roles of RocA in modulating iron homeostasis and also provide a candidate natural product on alleviating AI.

YI XUE BAN = JOURNAL OF PEKING UNIVERSITY. HEALTH SCIENCES 2024; 56:45-50.

Abstract
OBJECTIVE To investigate the differences and similarities of parameters associated with anemia of inflammation between patients with stage Ⅲ periodontitis and periodontally healthy volunteers, and to explore the influence of periodontal initial therapy on those indicators. METHODS Patients with stage Ⅲ periodontitis and periodontally healthy volunteers seeking periodontal treatment or prophylaxis at Department of Periodontology, Peking University School and Hospital of Stomatology from February 2020 to February 2023 were enrolled. Their demographic characteristics, periodontal parameters (including probing depth, clinical attachment loss, bleeding index), and fasting blood were gathered before periodontal initial therapy. Three months after periodontal initial therapy, the periodontal parameters of the patients with stage Ⅲ periodontitis were re-evaluated and their fasting blood was collected again. Blood routine examinations (including white blood cells, red blood cells, hemoglobin, packed cell volume, mean corpuscular volume of erythrocytes, and mean corpuscular hemoglobin concentration) were performed. And ferritin, hepcidin, erythropoietin (EPO) were detected with enzyme-linked immunosorbent assay (ELISA). All data analysis was done with SPSS 21.0, independent sample t test, paired t test, and analysis of covariance were used for comparison between the groups. RESULTS A total of 25 patients with stage Ⅲ periodontitis and 25 periodontally healthy volunteers were included in this study. The patients with stage Ⅲ periodontitis were significantly older than those in periodontally healthy status [(36.72±7.64) years vs. (31.44±7.52) years, P=0.017]. The patients with stage Ⅲ periodontitis showed lower serum hemoglobin [(134.92±12.71) g/L vs. (146.52±12.51) g/L, P=0.002] and higher serum ferritin [(225.08±103.36) μg/L vs. (155.19±115.38) μg/L, P=0.029], EPO [(41.28±12.58) IU/L vs. (28.38±10.52) IU/L, P < 0.001], and hepcidin [(48.03±34.44) μg/L vs. (27.42±15.00) μg/L, P=0.009] compared with periodontally healthy volunteers. After adjusting the age with the covariance analysis, these parameters (hemoglobin, ferritin, EPO, and hepcidin) showed the same trends as independent-sample t test with statistical significance. Three months after periodontal initial therapy, all the periodontal parameters showed statistically significant improvement. The serum hemoglobin raised [(146.05±15.48) g/L vs. (133.77± 13.15) g/L, P < 0.001], while the serum ferritin [(128.52±90.95) μg/L vs. (221.22±102.15) μg/L, P < 0.001], EPO [(27.66±19.67) IU/L vs. (39.63± 12.48) IU/L, P=0.004], and hepcidin [(32.54±18.67) μg/L vs. (48.18±36.74) μg/L, P=0.033] decreased compared with baseline. CONCLUSION Tendency of iron metabolism disorder and anemia of inflammation was observed in patients with stage Ⅲ periodontitis, which can be attenuated by periodontal initial therapy.

Roberts M, Jimson S, Srinivasan M. Are Adults Over 18 Years of Age with Anaemia More Likely to Develop Chronic Periodontitis Than Adults Without Anaemia? - A Systematic Review and Meta-Analysis. J Int Soc Prev Community Dent 2023; 13:287-298. [PMID: 37876584 PMCID: PMC10593371 DOI: 10.4103/jispcd.jispcd_37_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 07/10/2023] [Accepted: 07/13/2023] [Indexed: 10/26/2023] Open
Abstract
Aims and Objectives Periodontitis is a chronic disease affecting the supporting tissues of the teeth and exhibits bidirectional relation with systemic diseases. This study aims to determine the association between chronic periodontitis and erythrocyte functional measures: total red blood cells (RBCs), hemoglobin (Hb) concentration, mean corpuscular volume (MCV), and mean corpuscular hemoglobin concentration (MCHC) by systematic review and meta-analysis. Materials and Methods A systematic search of the electronic databases PUBMED, OVID, Embase, Web on Science, and Google Scholar was undertaken from inception to July 2022. English language studies that evaluated the erythrocyte functional measures in periodontitis and health were selected. Other review reports, letters/opinion articles, studies without a definition of periodontitis, and the concomitant presence of systemic conditions (diabetes, kidney disease, cancer) were excluded. Two reviewers determined full-text eligibility in a blinded process. Meta-Essentials software was used to generate forest plots and to determine heterogeneity and publication bias. Results Twenty-six studies involving 1082 patients with chronic periodontitis and 980 healthy controls were analyzed. Pooled results showed lower Hb concentration (Hedges' g = -1.16; 95% confidence intervals [CI], -1.7 to -0.62), RBC counts (Hedges' g = -0.85; 95% CI, -1.31 to -0.38) and packed cell volume (-0.56; 95% CI, -1.02 to -0.11) in patients with chronic periodontitis. Conclusion This meta-analysis showed a decreasing trend in the hematological parameters, including hemoglobin concentration, number of erythrocytes, and hematocrit in patients with chronic periodontitis compared to healthy controls.
