Farag AGA, Helal SG, Labib AZ, Bazid HAS. Study of calprotectin gene polymorphism and serum level in acne vulgaris patients. Int J Dermatol 2022; 61:1262-1269. [PMID: 35579306 DOI: 10.1111/ijd.16268] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/07/2021] [Revised: 02/20/2022] [Accepted: 04/23/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Acne vulgaris (AV) is an inflammatory skin disease of the pilosebaceous unit. S100A8 and S100A9 (the light subunits of calprotectin) gene polymorphisms have been known to be associated with inflammatory disorder. Until now, no study investigated calprotectin gene polymorphism in acne patients. OBJECTIVE This study was designed to investigate calprotectin serum levels and gene polymorphism (rs3806232) in acne vulgaris patients and to correlate them with different clinical aspects of them. METHODS This case-control study included 50 patients having variable degrees of acne vulgaris (AV) severity, in addition to a control group of 26 age- and gender-matched seemingly healthy volunteers. RESULTS Acne vulgaris patients had considerably greater (P < 0.001) mean serum calprotectin levels than the control group (3.86 ± 2.58 pg/ml vs. 0.29 ± 0.14). AA genotype of calprotectin S100 A8 (rs3806232) was significantly predominant over AG or GG genotypes in patients compared to the controls, and the A allele was significantly (P < 0.001) predominant in patients (80%), while A and G alleles were equally distributed in controls; also, there was a significantly higher serum calprotectin level in calprotectin AA genotype than in AG or GG (P < 0.001) in acne vulgaris patients. CONCLUSION The serum levels of calprotectin were considerably greater in AV patients than in controls. AA genotype and A allele of the S100 A8 gene were significantly higher in patients, which was associated with significantly higher calprotectin serum levels. Thus, calprotectin, both gene and serum level, might participate in disease pathogenesis, which needs further studies.

Abstract
BACKGROUND S100A8 single nucleotide polymorphism (SNP) and S100A8 blood level are related to many inflammatory disorders with no available conclusion in psoriasis. AIM to evaluate the possible role of S100A8 in psoriasis pathogenesis through analyzing its S100A8 (rs3806232) gene polymorphism and S100A8 serum level in psoriasis vulgaris patients, in addition to correlate the detected results with severity psoriasis in those patients. METHODS This case-control study was conducted on 50 patients having psoriasis vulgaris, and 26 controls. Severity of psoriasis was evaluated using psoriasis area and severity index (PASI) score. S100A8 serum level and S100A8 (rs3806232) SNP were evaluated by ELISA and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) respectively. RESULTS Serum S100A8 level was significantly higher in psoriatic patients than controls and was positively correlated with PASI score (r=0.826, p<0.001). S100A8 (rs3806232) AA genotype and A allele were significantly increased among psoriasis patients than controls (p<0.001) increasing risk of psoriasis development by about 5, 12 and 6 times than AG, GG and G allele. AA genotype was significantly associated with psoriasis severity (p=0.005), and high S100A8 serum levels (P= 0.018). CONCLUSIONS Circulating S100A8 could associated with disease severity and have an active role in psoriasis pathogenesis. S100A8 (rs3806232) SNP (AA genotype and A allele) might contribute to development and severity of psoriasis in the Egyptian population.

Abstract
Background & objectives Zinc alters gene expression mainly by binding to a site on the transcription factor. Genome-wide expression studies have shown early repression of genes related to zinc and immunity in adult patients with sepsis. The present study was conducted to evaluate the role of zinc supplementation on relative expression of immune response genes in neonatal sepsis. Methods In the present study, a sample of convenience of 22 neonates each was selected from the zinc supplemented and control groups using random numbers for expression of immune-related genes by zinc supplementation. These neonates with sepsis were earlier randomized into two groups: with and without zinc supplementation in addition to standard antibiotics and supportive care. Relative expression of immune response genes were analyzed for 22 neonates in each group using quantitative real-time PCR for calprotectin (S100A8/A9), tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), toll-like receptor-4 (TLR-4), cluster of differentiation 14 (CD14) and lipopolysaccharide-binding protein (LBP) genes. Results An increase in serum zinc levels was observed in zinc-supplemented group compared to controls. S100A8 gene showed downregulation by three-fold (P <0.001) and S100A9 gene showed upregulation by two-fold (P <0.05) in zinc group compared to controls. CD14 gene showed upregulation by one-fold in zinc-supplemented group compared to controls (P <0.05). No significant fold changes were observed with respect to TNF-α, IL-6, LBP and TLR-4 genes between the two groups. Interpretation & conclusions The results of our preliminary study showed that the zinc supplementation might modulates the relative expression of immune-related genes involved in sepsis pathway among neonates. However, studies with larger sample size are needed to be done to provide a better picture on the outcome by gene expression in neonatal sepsis by zinc supplementation.

Abstract
Periodontitis is a highly prevalent infectious disease, characterized by destruction of the periodontium, and is the main cause of tooth loss. Periodontitis is initiated by periodontal pathogens, while other risk factors including smoking, stress, and systemic diseases aggravate its progression. Periodontitis affects many people worldwide, but the molecular mechanisms by which pathogens and risk factors destroy the periodontium are unclear. Programmed cell death (PCD), different from necrosis, is an active cell death mediated by a cascade of gene expression events and can be mainly classified into apoptosis, autophagy, necroptosis, and pyroptosis. Although PCD is involved in many inflammatory diseases, its correlation with periodontitis is unclear. After reviewing the relevant published articles, we found that apoptosis has indeed been reported to play a role in periodontitis. However, the role of autophagy in periodontitis needs further verification. Additionally, implication of necroptosis or pyroptosis in periodontitis remains unknown. Therefore, we recommend future studies, which will unravel the pivotal role of PCD in periodontitis, allowing us to prevent, diagnose, and treat the disease, as well as predict its outcomes.

Abstract
Mucosal epithelial cells express an autonomous innate immune response that controls the overgrowth of invaded bacteria, mitigates the harmful effects of the bacteria carried within, and does not rely on other external arms of the immune response. Epithelial cell autonomous innate immunity "respects" the social biology of invading bacteria to achieve symbiosis, and is the primary protective mechanism against pathogens.

Abstract
Manganese (Mn) is a required cofactor for all forms of life. Given the importance of Mn to bacteria, the host has devised strategies to sequester Mn from invaders. In the macrophage phagosome, NRAMP1 removes Mn and other essential metals to starve intracellular pathogens; in the extracellular space, calprotectin chelates Mn and Zn. Calprotectin-mediated Mn sequestration is a newly appreciated host defense mechanism, and recent findings are highlighted herein. In order to acquire Mn when extracellular concentrations are low, bacteria have evolved efficient Mn acquisition systems that are under elegant transcriptional control. To counteract Mn overload, some bacteria possess Mn-specific export systems that are important in vivo, presumably for control of intracellular Mn levels. Mn transporters, their transcriptional regulators and some Mn-requiring enzymes are necessary for virulence of certain bacterial pathogens, as revealed by animal models of infection. Furthermore, Mn is an important facet of the cellular response to oxidative stress, a host antibacterial strategy. The battle for Mn between host and pathogen is now appreciated to be a major determinant of the outcome of infection. In this MicroReview, the contribution of Mn to the host-pathogen interaction is reviewed, and key questions are proposed for future study.

Abstract
There is recent and widespread interest in the damage-associated molecular pattern molecules S100A8 and S100A9 in cardiovascular science. These proteins have a number of interesting features and functions. For example, S100A8 and S100A9 (S100A8/A9) have both intracellular and extracellular actions, they are abundantly expressed in inflammatory and autoimmune states, primarily by myeloid cells but also by other vascular cells, and they modulate inflammatory processes, in part through Toll-like receptor 4 and the receptor for advanced glycation end products. S100A8/A9 also have anti-inflammatory and immune regulatory actions. Furthermore, increased plasma levels of S100A8/A9 predict cardiovascular events in humans, and deletion of these proteins partly protects Apoe(-)(/)(-) mice from atherosclerosis. Understanding the roles of S100A8 and S100A9 in vascular cell types and the mechanisms whereby these proteins mediate their biological effects may offer new therapeutic strategies to prevent, treat, and predict cardiovascular diseases.

Abstract
BACKGROUND AND OBJECTIVE Calprotectin is an important proinflammatory mediator in various inflammatory diseases and is composed of two subunits (S100A8 and S100A9). However, the level of calprotectin in plasma of patients with aggressive periodontitis and its relationship with gene polymorphisms of S100A8 are unclear. MATERIAL AND METHODS The plasma concentrations of calprotectin were measured, using an enzyme immunoassay, in 139 patients with aggressive periodontitis and in 88 periodontally healthy control subjects. These patients were genotyped for the rs3795391 and rs3806232 polymorphisms of S100A8. RESULTS The plasma concentration of calprotectin in patients with aggressive periodontitis was significantly higher than in controls (2.17 mg/L vs. 1.72 mg/L, respectively, p = 0.001). The percentage of the AA genotype of S100A8 rs3795391 was significantly higher in patients than in controls (82% vs. 69.3%, respectively, p = 0.027), while the frequency of the allele G was decreased among patients compared with controls (9.6% vs. 16.1%, respectively, p = 0.036), which was especially apparent in men (rs3795391 genotype, p = 0.005; rs3795391 allele, p = 0.015). The mean probing depth in patients carrying the AA genotype was significantly higher than that of patients carrying the GA + GG genotype of two polymorphisms of S100A8 (rs3795391, p = 0.035; rs3806232, p = 0.040), whereas the levels of calprotectin between different genotypes were not significantly different (rs3795391, p = 0.11; rs3806232, p = 0.15). CONCLUSION These findings indicate that aggressive periodontitis is associated with elevated levels of plasma calprotectin and that gene polymorphisms of S100A8 may influence the susceptibility and severity of aggressive periodontitis.

Abstract
We aimed to conduct a review of the literature for gene polymorphisms associated with chronic periodontitis (CP) susceptibility. A comprehensive search of the literature in English was performed using the keywords: periodontitis, periodontal disease, combined with the words genes, mutation, or polymorphism. Candidate gene polymorphism studies with a case-control design and reported genotype frequencies in CP patients were searched and reviewed. There is growing evidence that polymorphisms in the IL1, IL6, IL10, vitamin D receptor, and CD14 genes may be associated with CP in certain populations. However, carriage rates of the rare (R)-allele of any polymorphism varied considerably among studies and most of the studies appeared under-powered and did not correct for other risk factors. Larger cohorts, well-defined phenotypes, control for other risk factors, and analysis of multiple genes and polymorphisms within the same pathway are needed to get a more comprehensive insight into the contribution of gene polymorphisms in CP.

Abstract
BACKGROUND AND OBJECTIVE It is known that S100A8, a member of the S100 calcium-binding protein family, is associated with inflammatory diseases, including periodontitis. Our previous population-based study found an association between two polymorphisms, rs3795391 (A > G) and rs3806232 (A > G), in the upstream region of the S100A8 gene and aggressive periodontitis (AgP) in Chinese people. Based on those results, this investigation set out to analyze and corroborate whether the association also exists within families. MATERIAL AND METHODS Two hundred and four subjects from 73 nuclear families were recruited. All probands and their relatives were diagnosed according to the 1999 classification of periodontal diseases. Anticoagulated peripheral blood samples were collected from all the subjects, and DNA was extracted. The two single nucleotide polymorphisms (SNPs; rs3795391 and rs3806232) were detected and analyzed by standard polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. Analysis of genotype/allele was performed by Family-Based Association Test (FBAT) software ( http://www.biostat.harvard.edu/~fbat/default.html). RESULTS There was a statistically significant association of the SNP rs3795391 with AgP in the additive genetic model (chi(2) = 3.9836, d.f. = 1, p = 0.0459). Allele A showed significantly preferential transmission to the AgP affected individuals (Z = 1.996, p = 0.0459). The other SNP, rs3806232, showed no significant results in all models. CONCLUSIONS This family-based association study supports the previous findings that SNP rs3795391 (A > G) of the S100A8 gene might contribute to AgP susceptibility. This is, to our knowledge, the first investigation about AgP using FBAT in genetic analysis.
