ABSTRACT
OBJECTIVES: Cardiovascular disease (CVD) and periodontal disease have a common pathogenesis with inflammation and resolution steps. Although the relationships among periodontal disease, CVD, and specialized pro-resolving lipid mediator (sPRLM)s are well known, there is no study about the combined effects of cardiovascular and periodontal treatments on sPRLM levels. It was aimed to evaluate the effects of periodontal and cardiovascular therapies on sPRLMs (lipoxin A4, protectin (PD)1, resolvin (Rv) E1, RvD1, and maresin (MaR)1) in patients with CVD and periodontal disease. METHODS: This observational study consisted of fifty-five patients with CVD and mild or moderate periodontitis. The clinical periodontal parameters (plaque index, gingival index, probing pocket depth, percentage of bleeding on probing, and clinical attachment level) and blood and unstimulated total saliva samples were obtained at baseline, at 3 months (following only cardiovascular therapy), and at 6 months (following cardiovascular and periodontal therapies). The blood count and serum levels of cardiometabolic biomarkers (white blood cell, neutrophil/lymphocyte, serum total cholesterol (TC), triglyceride, and low and high-density lipoprotein (HDL) levels) were evaluated. sPRLMs were evaluated by ELISA. RESULTS: There were significant decreases in body mass index, clinical periodontal parameters, WBC, LDL, PD1, and RvD1 at 6 months compared to baseline. The decreases in TC/HDL, RvE1, and MaR1 levels were significant at 3 and 6 months compared to baseline (p < 0.05). CONCLUSION(S): The combination of cardiovascular and periodontal treatments leads to significant reductions in clinical periodontal and cardiometabolic parameters and sPRLMs. CLINICAL RELEVANCE: Our report, which is the first in their field, suggested that cardiovascular and periodontal therapies provide an important contribution via decreasing the periodontal and atherosclerotic inflammation modulating sPRLMs. This finding will be a big step toward increasing the quality of life in these patients by drawing attention to importance of public health associated with oral hygiene, periodontal health, and systemic phase of periodontal treatment.

BACKGROUND AND OBJECTIVE: The plasminogen (PLG) activation system plays an essential role in severe inflammation based diseases such as periodontitis, destructive membranous periodontal disease (ligneous periodontitis), familial Mediterranean fever (FMF), and amyloidosis. We have aimed to evaluate variations in PLG and the associations between PLG and MEFV genotypes in patients with FMF/ FMF-related secondary amyloidosis and periodontitis. MATERIAL AND METHODS: A total of 247 individuals who were either diagnosed with FMF or systemically healthy were recruited to this human observational study with a cross-sectional design. All individuals were also diagnosed with periodontitis or periodontally healthy. Blood samples were obtained from patients with FMF and systemically healthy controls. Clinical periodontal indicators were recorded. All polymorphisms located in exons 6 and 8 of PLG and mutations located on exons 2 and 10 of the MEFV gene were analyzed by DNA Sanger Sequencing. Genotypes and allele frequencies of PLG and MEFV were detected and tested by the Hardy-Weinberg equilibrium. Serum levels of amyloid A (SAA), high-sensitive C-reactive protein (hs-CRP), PLG, and salivary PLG levels were determined by using enzyme-linked immunosorbent assay (ELISA). RESULTS: Two polymorphisms were identified in PLG: G to A polymorphism on the 14th nucleotide of intron 8 and C to T polymorphism on the 924th nucleotide of the coding region (IVS 8+14 G>A and c.924C>T, respectively). In IVS 8+14 G>A polymorphisms, wild-type genotype: GG, heterozygote genotype: GA and homozygote genotype: AA. In c.924C>T polymorphism, wild-type genotype: CC, heterozygote genotype: CT and homozygote genotype: TT. The frequency of the heterozygous polymorphisms of PLG was significantly increased (17.6%) in FMF patients with periodontitis (p = .027). A large proportion of the test group that was heterozygous for MEFV-R202Q also had heterozygous PLG polymorphisms. Remarkable exacerbation in periodontal parameters was observed in patients with FMF and amyloidosis. SAA and hs-CRP levels were significantly correlated with salivary PLG levels in patients with periodontitis and heterozygous PLG. CONCLUSIONS: The current study describes IVS 8+14 G>A (rs2295368) and c.924C>T (rs1380916375) polymorphisms for the first time in the periodontal literature, which might play an important role in the pathogenesis of periodontitis, FMF, or amyloidosis. The elucidation of PLG polymorphisms is beneficial from a public health perspective by increasing the quality of life in these patients and reducing the mortality and morbidity associated with inflammatory diseases such as periodontal disease, FMF, and FMF-related amyloidosis.

Omega-3 and probiotics were shown to improve periodontal health by modulating the host immune response. Recently, the combination of omega-3 and probiotics has been shown to have a potential synergistic effect on host modulation. The aim of this study was to evaluate the prophylactic role of an omega-3 and probiotic combination on alveolar bone loss (ABL) via inflammatory response in an experimental periodontitis model. Forty-three rats were divided into 5 groups as control (C, n = 8), periodontitis (P, n = 8), omega-3 + periodontitis (O, n = 8), probiotic + periodontitis (Pro, n = 10), and omega-3 + probiotic + periodontitis (OPro, n = 9). Additionally to a standardized diet, omega-3 and/or probiotics were supplemented with oral gavage to the O, Pro, and OPro groups for 44 days. Periodontitis was induced by ligature to the P, O, Pro, and OPro groups on the 30th day for 2 weeks. ABL levels were measured histopathologically, and serum interleukin (IL) 1ß, IL6, and IL10 levels were analysed by enzyme-linked immunosorbent assay. ABL increased in all periodontitis groups (P, O, Pro, and OPro), compared to C group. Compared to P group, all oral gavage groups (O, Pro, and OPro) revealed decreased ABL, which was lowest in OPro group. IL1ß and IL6 decreased and IL10 increased in OPro group, compared to P group. In conclusion, prophylactic administration of omega-3 and probiotic combination reduced ABL and improved serum IL1ß, IL6, and IL10 levels more than their single use.

BACKGROUND AND OBJECTIVE: Periodontal disease and cardiovascular disease (CVD), which are both deemed to be triggered by inflammation, are recognized as public health problems. Evidence of host modulation via pro-resolving lipid shown in previous studies supports a two-way relationship between periodontitis and CVD. Last generation endogenous specific pro-resolution lipid mediators (SPMs) such as protectins (PDs) and maresins (MaRs) may have potential effects on inflammatory pathogenesis via activation and resolution mechanisms. Currently, there are no data on SPM levels in patients with CVD and periodontal disease. We aimed to evaluate salivary levels of PD and MaR in patients with CVD and periodontal disease. MATERIALS AND METHODS: At total of 181 individuals comprising of 79 healthy controls (C) and 102 patients with diagnosed CVD were included cross-sectionally. Unstimulated total salivary samples were obtained, and clinical periodontal parameters were determined. Salivary levels of PD and MaR were evaluated by ELISA. The periodontal status of the study population was classified as gingivitis (g) or periodontitis (p). RESULTS: Patients with CVD showed lower sociodemographic characteristics, increased clinical periodontal parameters (p < .05), decreased salivary PD (p < .001), and increased salivary MaR levels (p > .05). In the CVDg group, leukocyte, hemoglobin, hematocrit, and high-density lipoprotein values were higher (p < .05). The CVDp group had a higher neutrophil-to-lymphocyte ratio (p < .05). While the PD level was highest in the Cg group, MaR was highest in the CVDp group. The salivary levels of PD and MaR were independent of other confounders in CVD and periodontal disease (p > .05). CONCLUSION(S): PDs and MaRs may play effective roles in pathogenesis associated with worsening cardiometabolic and periodontal status. These SPMs could also be predictors for conversion from a healthy (systemically and periodontally) to diseased state (CVD and/or periodontitis). Elucidation of the role of SPMs in the relationship between periodontal disease and CVD will enable the development of new host modulation strategies in the prevention and treatment of both diseases, and may also constitute an important public health step by increasing the quality of life of patients with CVD and periodontal disease.

PURPOSE: The aim of this study was to evaluate the serum levels of oxidized low-density lipoprotein (oxLDL), anti-oxLDL, and myeloperoxidase (MPO) in hyperlipidemic patients with periodontal disease. METHODS: This study included 123 patients with hyperlipidemia categorized based on metabolic control as mild to moderate (H1) (n=66) or poor (H2) (n=57), as well as systemically healthy controls (C) (n=68). Serum levels of lipids, oxLDL, anti-oxLDL, and MPO were evaluated, along with clinical periodontal parameters. RESULTS: The percentage of bleeding on probing (BOP%) and the clinical attachment level were significantly higher in the H2 group than in the C group. Patients with hyperlipidemia had a relatively high risk of developing periodontal disease. The oxLDL and anti-oxLDL levels were higher in H2 patients with periodontitis than in the control or H1 patients with periodontitis. In the H1 and H2 groups, the ratio of total cholesterol to high-density lipoprotein was significantly correlated with gingival index, BOP%, and oxLDL levels. CONCLUSIONS: Our findings indicate that the lipoprotein-associated inflammatory mediators of oxLDL, anti-oxLDL, and MPO may play an important role in the relationship between periodontal disease and hyperlipidemia.
ABSTRACT
PURPOSE: An unresolved inflammatory state contributes to the pathogenesis of periodontal disease and metabolic syndrome (MetS). Therefore, the purpose of this study was to evaluate the role of lipoxin A4 (LXA4), a proresolving lipid mediator, in the association between periodontal disease and MetS. METHODS: Sixty-seven patients with MetS and 65 patients without MetS were included in the study. Sociodemographic information was obtained via a questionnaire, and detailed medical diagnoses were made. Periodontal parameters (plaque index [PI], gingival index [GI], probing pocket depth [PD], and clinical attachment level [CAL]) and metabolic parameters were measured, and serum LXA4 levels were determined. The associations among MetS, periodontal parameters, and serum LX levels were evaluated by adjusted multivariate linear regression analyses. RESULTS: Patients with MetS were older and had a higher body mass index than patients without MetS. Periodontal parameters (PI, GI, PD, and CAL) were higher in patients with MetS than in those without MetS. Serum LXA4 levels were higher in patients without MetS. Multivariate linear regression analysis indicated a positive association between MetS and periodontal parameters (PD and CAL). Negative associations were established between MetS and LXA4 levels, and between LXA4 and periodontal parameters (PI, PD, and CAL). CONCLUSIONS: The presence of higher values of periodontal parameters in patients with MetS and the negative relationship of LXA4 with MetS and periodontal disease may support the protective role of proresolving lipid mediators in the association between periodontal disease and MetS.
ABSTRACT
BACKGROUND: Familial Mediterranean fever (FMF) is an inherent autoinflammatory disease and have a high prevalence in Mediterranean countries. The aim of this study was to evaluate salivary levels of oxidative stress parameters in patients with FMF and chronic periodontitis. METHODS: The study population consists of 81 patients with FMF and 85 systemically healthy controls. The test and control groups were classified as chronic periodontitis and periodontally healthy [FMF-periodontitis (n = 37); FMF-periodontally healthy (n = 44); systemically healthy-periodontitis (n = 37); systemically and periodontally healthy (n = 48]. Total salivary samples were collected. Clinical periodontal parameters including plaque index, gingival index (GI), probing depth (PD), the percentage of bleeding on probing (BOP%), and clinical attachment level (CAL), were measured. Salivary total antioxidant status (TAS), total oxidant status (TOS), 8-hydroxydeoxyguanosine (8-OHdG), malondialdehyde (MDA), and oxidative stress index (OSI) were evaluated. RESULTS: The FMF-periodontitis group had significantly higher levels of 8-OHdG, MDA, and OSI than that of the FMF-periodontally healthy group. In the FMF-periodontitis group, PD, 8-OHdG, MDA, and OSI levels were significantly higher than in the systemically healthy-periodontitis group (P = 0.035, P = 0.000, P = 0.000, and P = 0.000, respectively). 8-OHdG values were significantly correlated with BOP% and GI, and TOS values were significantly correlated with PD and CAL in the FMF-periodontitis group. CONCLUSIONS: In the presence of FMF and chronic periodontitis, there were increased salivary levels of oxidative stress. Thus, oxidative stress could be an important inflammatory mechanism in the FMF and chronic periodontitis. Further studies need to clarify the oxidative mechanisms of FMF and chronic periodontitis.

BACKGROUND: Periodontal disease is shown to be aggravated by an increase in the count of metabolic risk factors. This study aims to evaluate the effects of metabolic risk factors on periodontal parameters and salivary oxidative stress markers related to menopausal status. METHODS: One hundred and seventy-six women were categorized according to menopausal status, either premenopause (Pre/M) (n = 86) or postmenopause (Post/M) (n = 90). The count of metabolic risk factors was evaluated. Sociodemographics and systemic status were determined via questionnaire and medical records. After clinical periodontal measurements and saliva collection, myeloperoxidase (MPO), total oxidant status (TOS) and total antioxidant capacity (TAOC) were determined by enzyme-linked immunosorbent assay and automatic colorimetric method. Oxidative stress index (OSI) was also calculated. RESULTS: The count of metabolic risk factors was higher in the Post/M group than the Pre/M group. Periodontal parameters and TOS levels were elevated by an increase in the count of metabolic risk factors. Multivariate regression analyses revealed that periodontal (clinical attachment level and missed teeth) and oxidative (MPO and OSI) parameters increased and TAOC levels decreased due to menopause. Additionally, positive relationships between periodontal and oxidative parameters were determined. CONCLUSION: These findings suggest that salivary oxidative stress level may be an indicator of worsened periodontal status related to menopause and the count of metabolic risk factors.

BACKGROUND: There are no published studies regarding the role of the plasminogen (PLG) system in familial Mediterranean fever (FMF), FMF-associated secondary amyloidosis, or chronic periodontitis (CP), although recent limited data have focused on the association between FMF and chronic periodontitis. Therefore, the aim of this study was to evaluate the serum, salivary, and gingival tissue levels of PLG in patients with CP, FMF, and amyloidosis. METHODS: The study population included 122 patients with FMF (only FMF, and FMF and amyloidosis and 128 individuals who were systemically healthy controls. Blood and salivary samples were obtained from the cases and controls, and clinical periodontal parameters were recorded. Serum and salivary PLG levels were assessed. The gingival tissue samples of the case and control groups were analyzed histopathologically and immunohistochemically for amyloid deposition and PLG. RESULTS: The amyloidosis group had significantly more severe clinical periodontal parameters than those of the FMF and systemically healthy groups (P < 0.05). Salivary levels of PLG were significantly higher in the FMF and amyloidosis groups compared with those in the control group (P < 0.001). The FMF with periodontitis and amyloidosis with periodontitis groups had higher salivary PLG levels compared with those in the CP group. Serum and salivary PLG levels were significantly associated with the clinical periodontal parameters in the FMF group. The amyloidosis cases had hyperplasia, severe inflammation, and activation of the gingiva. CONCLUSION: The PLG system could play an important role in inflammatory diseases, such as chronic periodontitis, FMF, and FMF-associated secondary amyloidosis.

OBJECTIVE: Impairment of the lipid metabolism could affect the periodontal disease; increased oxidative stress may have a role in this relationship. The aim of the present study was to evaluate the role of menopause in the relationship between hyperlipidemia and periodontal disease via oxidative stress markers in saliva. MATERIALS AND METHODS: Sixty-seven women were enrolled in the study and divided into four groups as systemically healthy and premenopause (C) (n = 18), hyperlipidemia and premenopause (H) (n = 16), systemically healthy and postmenopause (M) (n = 17), and hyperlipidemia and postmenopause (MH) (n = 16). Sociodemographics, periodontal and metabolic parameters, and saliva oxidative markers (myeloperoxidase [MPO] and 8-hydroxy-2'-deoxyguanosine [8-OHdG]) were evaluated. RESULTS: Menopause and/or hyperlipidemia were associated with an increase in all evaluated periodontal parameters. Saliva 8-OHdG and MPO levels were higher in menopausal groups (M and MH). Multivariate linear regression analyses revealed that hyperlipidemia was related to an increase in periodontal parameters. Salivary oxidative stress markers and periodontal parameters were also positively associated with menopause and hyperlipidemia. CONCLUSION: Saliva 8-OHdG and MPO levels may indicate that the relationship between periodontal disease and hyperlipidemia is aggravated by menopause.

The effects of systemically administered rosuvastatin on alveolar bone loss (ABL), cytokine levels and oxidative status were investigated in rats with ligature-induced periodontitis. Rats were divided randomly into four groups: a non-ligated group (C); a non-ligated+rosuvastatin group (R); a ligated group (P); and a ligated+rosuvastatin group (PR). Ligatures were placed at the maxillary second molars, and rosuvastatin was administered for 14 days. After the rats had been euthanatized, histomorphometric and histological analyses were performed, and the serum levels of interleukin (IL)-1ß, IL-10 and oxidant and antioxidant parameters (malondialdehyde [MDA], superoxide dismutase, glutathione, and glutathione peroxidase) were evaluted by enzyme-linked immunosorbent assay. Rosuvastatin significantly decreased the extent of ABL, inflammatory infiltration and osteoclasts in periodontitis, but increased the numbers of osteoblasts. Although rosuvastatin reduced the levels of IL-1ß, they did not differ significantly between the PR and P groups. In the PR group, not only were IL-10 levels significantly higher but also the ratio of IL-1ß to IL-10 was lower than in the P group. Although MDA levels were significantly increased in the P group relative to the C group, they did not differ significantly between the PR and C groups. The present data suggest that rosuvastatin decreases ABL in ligature-induced periodontitis, and that its anti-inflammatory effect is more remarkable than its antioxidant effect.

The aim of this study was to evaluate the effects of melatonin on the oxidative stress in heart tissues after induction of experimental periodontitis in rats. Thirty Wistar Albino male rats were divided into four groups as follows: healthy + saline solution (Hs, n = 7), healthy + melatonin (Hm, n = 7), periodontitis + saline solution (Ps, n = 8), and periodontitis + melatonin (Pm, n = 8). Experimental periodontitis was induced using a ligature placed at the gingival margin of the maxillary second molars. Melatonin was applied intraperitoneally (10 mg/kg) every day for 2 weeks. After sacrificing the rats, serum levels of malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) levels, and melatonin levels were evaluated. The Pm group exhibited lower alveolar bone loss than the Ps group. Melatonin levels increased in the periodontitis groups, and the Pm group had lower MDA levels and higher GSH-Px levels than the Ps group. These findings suggest that melatonin administration reduces MDA and increases GSH-Px levels in heart tissue, and these effects may be due to its antioxidant properties. Further studies are needed to understand the effects of melatonin on the association between periodontitis and cardiovascular disease.

BACKGROUND: This study aims to investigate the effects of a 2% cholesterol-enriched diet on alveolar bone loss (ABL) and serum levels of pro-oxidants and antioxidant enzymes in rats with experimental periodontitis. METHODS: Rats were randomized into the four groups: 1) group C (standard diet/periodontally healthy); 2) group Hc (high-cholesterol diet); 3) group HcP (high-cholesterol diet/periodontitis); and 4) group P (standard diet/periodontitis). All rats were fed for 8 weeks. At 6 weeks, experimental periodontitis was induced. At the end of week 8, the rats were sacrificed. Histomorphometric and histopathologic analyses were performed. Malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase, and glutathione peroxidase (GPX) levels in serum were measured with enzyme-linked immunosorbent assay. RESULTS: Experimental groups exhibited increases in: 1) total cholesterol, 2) low-density lipoprotein, and 3) high-density lipoprotein compared to group C. The cholesterol-enriched diet induced ABL in group Hc; groups HcP and P had more extensive ABL. The most polymorphonuclear leukocyte infiltration in periodontal tissues was found in group HcP. MDA levels were higher in all experimental groups than in group C, but significant in the HcP group. A high-cholesterol diet, with or without periodontitis, resulted in more decreases in GPX and more increases in NO compared to group P. CONCLUSION: Although any additive effect of cholesterol-enriched diet to ABL was not found in rats with ligature-induced experimental periodontitis, these findings revealed that a cholesterol-enriched diet could lead to ABL and an increase in periodontal inflammation and serum pro-oxidants.

BACKGROUND/AIM: To evaluate the effects of periodontal treatment on serum lipoprotein-associated phospholipase A2 (Lp-PLA2) and C-reactive protein (CRP) levels in hyperlipidaemic patients with periodontitis. MATERIALS AND METHODS: The study included 52 hyperlipidaemics and 28 systemically healthy controls (C) with periodontitis. Of the 52 hyperlipidaemics, 29 received a suggested diet (HD), and 23 of them were prescribed statin (HS). Clinical periodontal parameters, serum lipids, Lp-PLA2, and CRP levels were assessed at the baseline and 2 months after the completion of the nonsurgical periodontal treatment (2MPT). Serum parameters were also evaluated 1 week following the periodontal treatment (1WPT). RESULTS: At the baseline, patients in the HS group had a higher percentage of bleeding on probing than those in the C and HD groups. Hyperlipidaemics had higher serum triglyceride levels than the control group at 2MPT compared to the baseline. At 2MPT, the levels of Lp-PLA2 in the HS group were significantly higher compared to the baseline and 1WPT. There were no statistically significant differences in CRP levels between study periods for all groups. CONCLUSION: The periodontal treatment may affect the inflammatory control of hyperlipidaemic patients with periodontitis via increased Lp-PLA2 levels and severity of the impaired lipid metabolism. These findings may be important regarding the therapeutic strategies for hyperlipidaemics with periodontitis.

BACKGROUND: The aim of this study was to evaluate the serum lipoxin A4 (LXA4) and neutrophil/lymphocyte (Ne/Ly) ratio in individuals with achieved systemic risk factors for periodontitis. MATERIAL AND METHODS: One hundred and eighty volunteers (69 male, 111 female) who were categorized as systemically healthy control, diabetes, hyperlipidemia, obese and menopause were recruited for this cross-sectional study. Sociodemographic characteristics and oral health behaviors were recorded via questionnaire. Clinical periodontal parameters, including plaque index (PI), gingival index (GI), probing pocket depth (PD), clinical attachment level (CAL), sulcus bleeding index (SBI) and decayed, missing, and filled teeth index (DMFT), were assessed. Systemic parameters and LXA4 levels were evaluated in serum samples. RESULTS: Clinical periodontal parameters and DMFT were higher in subjects with achieved systemic risk factors than in healthy subjects. The systemically healthy with periodontitis group had higher serum LXA4 levels than the systemically healthy with non-periodontitis group (P<0.05). The Ne/Ly ratio was higher in the hyperlipidemic group with periodontitis than in the hyperlipidemic group with non-periodontitis (P<0.05). In the control group, serum LXA4 levels were positively correlated with the PD, CAL and SBI. CONCLUSIONS: In the presence of periodontitis, an increase in LXA4 levels and the Ne/Ly ratio in hyperlipidemic patients could contribute to the hypothesis that these parameters could be an indicator in periodontitis and its systemic risk factors.

BACKGROUND: The purpose of this study is to determine the serum levels of malondialdehyde (MDA), as a lipid peroxidation marker, and 8-hydroxydeoxyguanosine (8-OHdG), as an oxidative DNA damage marker, in patients with chronic periodontitis (CP) and hyperlipidemia. METHODS: A total of 74 individuals were divided into four age- and sex-matched groups: 18 patients with hyperlipidemia and CP (HLp), 18 periodontally healthy patients with hyperlipidemia (HLh), 19 systemically healthy individuals with CP (Cp), and 19 systemically and periodontally healthy controls (Ch). Clinical periodontal parameters were measured, and serum lipids, MDA, and 8-OHdG levels were assessed in blood samples. RESULTS: 8-OHdG, MDA, probing depth, clinical attachment level, and percentage of sites bleeding on probing (BOP) were significantly higher in the HLp group than the Cp group. In the hyperlipidemic group, BOP was significantly correlated with total cholesterol, the ratio of total cholesterol to high-density lipoprotein cholesterol, and 8-OHdG levels. A significant correlation between 8-OHdG and MDA was also observed in the hyperlipidemia group. CONCLUSIONS: In this study, serum MDA and 8-OHdG were found to be highest in the HLp group. The increased levels of MDA and 8-OHdG in HLp patients may be a result of a harmful oxidative status in association with hyperlipidemia and periodontitis.

INTRODUCTION: Renal amyloidosis may lead to renal disease, and then nephrotic syndrome may develop. To the best of the authors' knowledge, this is the first case report in which a patient presents with generalized aggressive periodontitis (GAgP) and nephrotic syndrome in conjunction with renal amyloidosis. CASE PRESENTATION: An 18-year-old male presented to the periodontology department for generalized gingival recessions. He was diagnosed as having primary renal amyloidosis by his physician. The patient presented with severe gingival inflammation and alveolar bone loss. Biochemical tests were within normal limits except for serum albumin level. No amyloid deposition was found in a gingival biopsy, and the patient was diagnosed as having GAgP. Non-surgical periodontal treatment, in combination with antibiotic treatment, was performed. After 3 years, his systemic and periodontal conditions showed deterioration. CONCLUSIONS: The effects of systemic factors related to nephrotic syndrome in conjunction with renal amyloidosis and deterioration in oral hygiene may play a significant role in the progression of periodontal disease. Even if there is no amyloid deposition in periodontal tissues, clinicians should consider that nephrotic syndrome associated with systemic amyloidosis may provide an important contribution to the periodontal breakdown by the modifying conditions that affect the host response to the accumulation of dental biofilm.
ABSTRACT
BACKGROUND: Several studies have shown a possible association between periodontal disease and obesity. The aim of this study is to evaluate serum plasminogen activator inhibitor 1 (PAI-1), tumor necrosis factor-alpha (TNF-α), and high-sensitivity C-reactive protein (hsCRP) levels in the association between obesity and periodontal disease. METHODS: Two hundred individuals participated in this study. Body mass index (BMI), waist-to-hip ratio, plasma triglyceride (TRG), total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), fasting blood glucose (FBG), hsCRP, TNF-α, PAI-1, and periodontal parameters (including plaque index [PI], probing depth [PD], clinical attachment level [CAL], and percentage of sites with bleeding on probing) were evaluated. RESULTS: The groups with BMI ≥ 25 had higher median values for FBG, TRG, hsCRP, PAI-1, PI, and CAL than did the groups with a BMI < 25 (P <0.01). Serum TRG levels were positively correlated with PI, PD, and CAL. There were negative associations between clinical periodontal parameters and HDL-C. There were statistically significant correlations between PAI-1 and clinical periodontal parameters (PI, PD, and CAL). CONCLUSION: Serum PAI-1 levels may play an important role in the association between periodontal disease and obesity.

BACKGROUND: The aim of this study is the evaluation of levels of serum interleukin (IL)-1ß, IL-6, IL-10, tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), placental growth factor (PIGF), and soluble VEGF receptor (sVEGFR)-1 and -2 in the association between periodontal disease and adverse pregnancy outcomes. METHODS: One hundred and nine mothers, who recently gave birth, and 51 women who were not recently pregnant, aged 18 to 35 years, were included in this study. The mothers were classified as term birth, preterm birth (PTB), and preterm low birth weight (PLBW) in respect to their gestational age and baby's birth weight. The birth mothers were grouped as having gingivitis or periodontitis. The non-pregnant group also included periodontally healthy patients. Venous blood samples were collected to evaluate serum IL-1ß, IL-6, IL-10, TNF-α, VEGF, PIGF, and sVEGFR-1 and -2 levels. RESULTS: Mother's weight, education, and income level were significantly associated with pregnancy outcomes. Serum levels of IL-1ß, TNF-α, IL-6, VEGF, and sVEGFR-1 and -2 showed an increase in significance when related to pregnancy. Whereas in the PLBW group IL-1ß, VEGF, and sVEGFR-2 levels were increased, in the PTB group sVEGFR-1 levels were increased. Additionally, the patients in the PLBW group with periodontitis had higher serum levels of IL-1ß, VEGF, sVEGFR-2, and IL-1ß/IL-10. CONCLUSION: The serum levels of IL-1ß, VEGF, and sVEGFR-1 and -2 may have a potential effect on the mechanism of the association between periodontal disease and adverse pregnancy outcomes.

BACKGROUND: The aim of this study is to evaluate the levels of serum lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) and high-sensitivity C-reactive protein (hsCRP) in association with periodontal disease and hyperlipidemia. METHODS: A total of 123 subjects with hyperlipidemia and 68 systemically healthy controls were included in the study. Subjects with hyperlipidemia were divided into two groups: the suggested-diet (HD) and prescribed-statin (HS) groups and then into three subgroups: the healthy (HDh and HSh), gingivitis (HDg and HSg), and periodontitis (HDp and HSp) groups. Periodontal parameters were recorded and included the plaque index, gingival index (GI), probing depth (PD), clinical attachment level (CAL), and percentage of sites with bleeding on probing (BOP). Fasting venous blood samples were obtained, and serum lipid, Lp-PLA(2), and hsCRP levels were evaluated. RESULTS: Median values for the GI, PD, BOP(%), and CAL in the HSg group were statistically significantly higher than those in the HDg and systemically healthy with gingivitis (Cg) groups. The HSp group had higher percentages of BOP compared to those of the chronic periodontitis and HDp groups. The HDg group had higher serum Lp-PLA(2) and hsCRP levels compared to those of the Cg and HSg groups. The ratio of total cholesterol to high-density lipoprotein cholesterol (TC/HDL) was significantly associated with the GI, PD, and BOP(%) in both groups with hyperlipidemia. Serum Lp-PLA(2) and hsCRP levels were significantly correlated with TC/HDL, the GI, PD, and BOP(%) in the HD group. CONCLUSIONS: Serum Lp-PLA(2) and hsCRP levels may play an important role in the association between periodontal disease and hyperlipidemia, and the control of these mediators may affect the inflammatory control of patients with hyperlipidemia and periodontal disease.
