ABSTRACT

Background: Identifying factors related to persistent human papillomavirus (HPV) infection is essential to reduce the incidence of HPV-related cancers. Objective: To evaluate whether gingival/periodontal inflammation is associated with oral HPV infection. Methods: This cross-sectional study (n = 740) uses data from the follow-up visit of the San Juan Overweight Adults Longitudinal Study, which recruited overweight/obese adults aged 40-65 from Puerto Rico. Participants completed a dental examination and two interviews (face-to-face/ACASI) and provided oral rinse samples for HPV detection. Oral inflammation was assessed using two definitions: (1) the number of sites with bleeding on probing (BOP), and (2) the number of teeth with probing pocket depths (PPD) ≥ 4 mm and BOP. Multivariate logistic regression was used to assess the association between oral inflammation and oral HPV. Results: Nearly three-quarters (72%) of participants were female, and 68% had 50 years or older. Participants with HPV had a higher mean number of sites with BOP (15.5 vs. 10.1) and teeth with PPD ≥ 4 mm and BOP (8.5 vs. 3.2) than participants without HPV (p < 0.05). After adjusting for sex, age, income, and the number of oral sex partners, the odds of having an oral HPV infection increased by 3% (95% confidence interval (CI): 1.00-1.06) for any additional sites with BOP and 5% (95% CI: 1.02-1.09) for any other teeth with PPD ≥ 4 mm and BOP. Conclusions: We found that oral inflammation was associated with oral HPV infection among adults in Puerto Rico. Future studies need to further investigate the underlying mechanisms.

ABSTRACT

Periodontal disease (PD) is prevalent in type 2 diabetic condition (T2DM). OBJECTIVES: We assessed the associations between serum or gingival crevicular fluid (GCF) endothelial and inflammatory mediators and chronic PD among T2DM Hispanic adults. METHODS: We enrolled 248 Puerto Rican residents with T2DM aged 40-65 years. The exposures included serum inflammatory mediators (IL-1b, IL-6, IL-10, and TNF-α), endothelial adhesion molecules, RANKL levels, and the GCF content of these analytes from a subset of 158 samples. The outcomes included the percent of sites with a probing pocket depth (PPD) ≥ 4 mm and clinical attachment loss ≥ 4 mm. Adjusted logistic regression models were fit to the categorized outcomes. RESULTS: Increased serum IL-10 (Adj. OR: 1.10, p = 0.04), sICAM-1 (Adj. OR: 1.01; p = 0.06), and elevated serum IL-1ß (Adj. OR: 1.93; p = 0.06) were statistically significant or close to being significantly associated with a percent of sites with PPD ≥ 4 mm. An increase in GCF IL-1α (Adj. OR: 1.16; p < 0.01) and IL-1ß (Adj: 2.40; p = 0.02) was associated with periodontal parameters. CONCLUSIONS: Our findings suggested that oral and systemic endothelial and inflammatory mediators are associated with periodontal clinical parameters among Hispanic adults with T2DM.

ABSTRACT

The network interaction between systemic inflammatory mediators, endothelial cell adhesion function, and adiponectin as mediators of the association between metabolic diseases and periodontitis has not been evaluated. The objective of this study is to assess whether the interaction of baseline serum levels of TNF-α, hs-CRP, ICAM-1, VCAM-1, and adiponectin leads to periodontitis. Five hundred and ninety-seven overweight/obese (overweight: BMI 25 to <30 kg/m2; obese: >30 kg/m2) adults, aged 40-65 years, with complete 3-year follow-up data were included. Generalized structural equation models with negative binomial regression were used to estimate the regression coefficient (ß) for the outcome number of teeth with probing pocket depth (PPD) ≥ 4 mm and bleeding on probing (BOP) at 3-year follow-up for a 1 standard deviation unit increase (Δ = +1SD) in each biomarker. After adjusting for multiple covariates, baseline ICAM-1 and VCAM-1 had significant direct effects on increased log-transformed number of teeth with PPD ≥ 4 mm and BOP (ß: 0.16; 95% CI: 0.02-0.30; ß: 0.15; 95% CI: 0.02-0.30, respectively). Baseline hs-CRP showed a significant indirect effect via ICAM-1 on the log-transformed number of teeth with PPD ≥ 4 mm and BOP (ß: 4.84; 95% CI: 0.27-9.42). Thus, elevated serum ICAM-1 and VCAM-1 have a significant direct effect and increased hs-CRP has a significant indirect effect on the predicted level of periodontitis at the 3-year follow-up among overweight/obese Hispanic adults.

ABSTRACT

Background: Individuals with diabetes frequently have comorbid health conditions and suffer longer term complications. The control of blood glucose relies on diabetes management/self-care behaviors. Poor glycemic control, commonly encountered in underserved populations with type 2 diabetes (T2D) often results from inadequate diabetes self-care activities and/or perception. We aimed to assess the association between diabetes self-care activities/perception and glycemic control in adult Puerto Rican residents with T2D. Design and methods: We used a cross-sectional study design; our sample population was 260 individuals aged 40-65 years with T2D. We asked participants about their diabetes self-care over 8 weeks. High fasting blood glucose (≥130 mg/dL) and glycated hemoglobin (HbA1c; ≥7%) measures were defined. We estimated the strength of the following associations using logistic regression: each of three self-care activities and fasting glucose or HbA1c, adjusting for confounders. Results: Nearly 27% of the participants reported not checking their glucose levels, 7% did not take their medications as prescribed and 31% perceived their diabetes self-care as poor. Participants with less education perceived their diabetes self-care as poor more often than their counterparts (44% vs 25%; p = 0.003). Most participants had high glycemic levels (60%) or hbA1c levels (65%). Participants who perceived their diabetes self-care as poor had higher HbA1c levels than their counterparts (adj. odds ratio: 2.14, 95% CI (1.13, 4.08)). Conclusion: Poor diabetes self-care perception, possibly related to less education, likely explains poor glycemic control among adult Puerto Rican residents with T2D.

ABSTRACT

We evaluated the relationship between glucose abnormalities and periodontitis in overweight/obese individuals. Eight hundred and seventy (870) diabetes-free participants aged 40-65 years completed the three-year follow-up in the San Juan Overweight Adults Longitudinal Study. The ADA thresholds for fasting and 2-h post-load glucose and HbA1c were used to define prediabetes. The NHANES methods were used to assess periodontitis. Multivariable linear regression was used to evaluate the relationship between baseline glucose metabolism measures and periodontitis at follow-up, adjusting for potential confounders. There was no association between impaired glucose measures and mean pocket depth (PD), mean clinical attachment loss (CAL), or mean percent of sites ≥5 mm PD. Impaired glucose tolerance (IGT) was associated with a lower mean percent of sites ≥5 mm CAL (ß = -1.6, p = 0.037). Prediabetes and impaired fasting glucose (IFG) were associated with improvement in mean percent of sites ≥5 mm PD (ß = -1.4, p = 0.022; ß = -1.6, p = 0.032; respectively). IFG and IGT were associated with improvement in mean percent of sites with ≥5 mm CAL (ß = -1.6, p = 0.038; ß = -1.9, p = 0.020; respectively). In conclusion, there were no consistent associations between baseline prediabetes or insulin resistance and periodontitis progression over a three-year period.

ABSTRACT

This is the first longitudinal study evaluating whether adiposity is associated with inter-arm blood pressure difference. We evaluated 714 overweight/obese individuals aged 40-65 years over a 3-year follow-up. Systolic and diastolic blood pressures were measured in both arms simultaneously using an automated machine. Linear regression assessed the associations of body mass index, fat %, waist, neck, thigh, and arm circumferences (cm), with absolute inter-arm differences in systolic (IAS) and diastolic (IAD) blood pressure (mm Hg). Poisson regression was used for binary outcomes (IAS and IAD ≥ 10 mm Hg). All models were adjusted for age, gender, smoking, physical activity, and HOMA-IR. Adiposity measures were associated with increased IAS and IAD (ß range: 0.09-0.20 and 0.09-0.30). Neck circumference showed the strongest association with IAS (ß = 0.20, 95% CI: 0.03, 0.37) and IAD (ß = 0.30, 95% CI: 0.12, 0.47); arm circumference showed a similar association with IAS, but lower with IAD. Highest quartiles of BMI, thigh, and arm showed significant associations with IAS (IRR: 2.21, 2.46 and 2.70). Highest quartiles of BMI, waist, neck, and arm circumferences were significantly associated with IAD (IRR: 2.38, 2.68, 4.50 and 2.24). If the associations are corroborated in other populations, adiposity may be an important modifiable risk factor for inter-arm blood pressure difference with a large potential public health impact.

ABSTRACT

PURPOSE OF REVIEW: Research suggests that periodontal tissue might serve as a reservoir for oral human papillomavirus (HPV) infection, while another hypothesis is that chronic inflammation of the tissue might perpetuate an infection with oral HPV infection. In this narrative review, we summarize the evidence related to a potential association between oral HPV infection and periodontitis. RECENT FINDINGS: Twelve articles were identified, and their key findings summarized. Studies vary in sample size, study population, study design, and methods for assessment of oral HPV and periodontitis. Although results are conflicting and still inconclusive, various studies have found an association between oral HPV infection and periodontitis, which is supported by biological plausibility. SUMMARY: Future longitudinal studies should further evaluate this association, using clinical definitions of oral HPV infection and periodontitis, and focusing on high-risk populations for oral HPV infection. Studying this association is important since periodontitis might help identify at-risk individuals for oral HPV infection and potentially HPV-related oropharyngeal cancers.

ABSTRACT

OBJECTIVES: Evaluate whether insulin resistance (IR) predicts the risk of oral inflammation, assessed as the number of sites with bleeding on probing (BOP) and number of teeth with probing pocket depths (PPD) ≥ 4 mm and BOP. METHODS: Data on 870 overweight/obese diabetes free adults, aged 40-65 years from the San Juan Overweight Adults Longitudinal Study over a three-year period, was analyzed. Baseline IR, assessed using the Homeostasis Model Assessment of IR (HOMA-IR) index, was divided into tertiles. BOP was assessed at buccal and lingual sites, and PPD at six sites per tooth. Negative binomial regression was used to estimate the risk ratios (RRs) for oral inflammation adjusted for baseline age, gender, smoking status, alcohol intake, education, physical activity, waist circumference, mean plaque index, and baseline number of sites with BOP, or number of teeth with PPD≥4 mm and BOP. The potential impact of tertiles of serum TNF-α and adiponectin on the IR-oral inflammation association was also assessed in a subsample of 597 participants. RESULTS: Participants in the highest HOMA-IR tertile at baseline had significantly higher numbers of sites with BOP [RR = 1.19, 95% confidence interval (CI): 1.03-1.36] and number of teeth with PPD ≥ 4 mm and BOP (RR = 1.39, 95% CI: 1.09-1.78) at follow-up, compared with individuals in the lower two HOMA-IR tertiles. Neither TNF-α nor adiponectin confounded the associations. CONCLUSION: IR significantly predicts gingival/periodontal inflammation in this population.

ABSTRACT

AIM: This study assessed the associations of pre-diabetes and insulin resistance with bleeding on probing (BOP) and periodontitis among adults. MATERIALS AND METHODS: We included 1191 Hispanic adults aged 40-65 years, free of diabetes, enrolled in San Juan Overweight Adults Longitudinal Study. Pre-diabetes was defined as impaired fasting glucose (IFG), impaired glucose tolerance (IGT), or impaired glycated haemoglobin. Impaired one-hour plasma glucose (1hPG) was defined as levels >155 mg/dl. Insulin resistance was defined using the study population-specific 75th percentile (HOMA-IR ≥ 3.13). High BOP was defined as percentage of teeth with bleeding ≥30%. Periodontitis was defined according to the CDC/AAP definition. RESULTS: After multivariable adjustment for age, gender, education, smoking status, alcohol consumption, physical activity, obesity, HDL-C, and plaque index, pre-diabetes with and without 1hPG, IFG, impaired 1hPG, IGT, and HOMA-IR were significantly associated with high BOP; pre-diabetes, IFG, and impaired 1hPG were significantly associated with severe periodontitis. Most of these associations remained significant when the analyses were restricted to non-smokers. CONCLUSIONS: This study suggests associations between pre-diabetes and insulin resistance with BOP and periodontitis. Given the high prevalence of impaired glucose metabolism and periodontitis, the assessment of the temporal sequence of these associations is of utmost importance.

ABSTRACT

BACKGROUND: The effect of the interaction between type 2 diabetes and dyslipidemia on inflammation and lipid peroxidation (LPO) has not been assessed. AIM: To investigate whether diabetes coupled with dyslipidemia alters oxidative metabolism leading to increased LPO products and inflammatory status. METHODS: 100 patients were divided into four groups based upon diabetic and dyslipidemic status: poorly controlled diabetes with dyslipidemia (DM-PC/D), well-controlled diabetes with dyslipidemia (DM-WC/D), normoglycemic individuals with dyslipidemia (NG/D), and normoglycemic individuals without dyslipidemia (NG/ND). Plasma was evaluated for an LPO product (MDA), antioxidant levels and inflammatory cytokines. RESULTS: Diabetics presented significantly higher levels of LPO (p<0.05) and the DM-PC/D had higher levels of proinflammatory cytokines and MDA in the plasma in comparison with normoglycemics (p<0.05). Interestingly IL1-ß, IL-6, and TNF-α in DM-WC/D were not statistically different from those in DM-PC/D. Normoglycemic individuals with dyslipidemia presented significantly increased levels of IL-6 and TNF-α when compared to normoglycemic without dyslipidemia (p<0.05). MDA levels were also positively correlated with the presence of DM complications (r=0.42, p<0.01). CONCLUSIONS: These findings show that dyslipidemia is associated with an increased inflammatory status, even in well-controlled diabetics and in normoglycemics. Our results suggest that lipid metabolism and peroxidation are important for the development of inflammation, which is elevated in several complications associated with diabetes.

ABSTRACT

AIM: To assess the relationship between oral health and asthma. METHODS: Data from 1315 overweight or obese individuals, aged 40-65 years were used. Asthma was self-reported, whereas periodontitis, bleeding on probing (BOP) and plaque index were determined by clinical examinations. RESULTS: Using logistic regression adjusting for gender, smoking status, age, body mass index, family history of asthma and income level, revealed that the odds ratio (OR) of asthma for a participant with severe periodontitis was 0.44 (95% confidence interval: 0.27, 0.70) that of a participant with none/mild periodontitis. On the other hand, proportion of BOP sites and plaque index were not statistically significant. For a participant with severe periodontitis, the OR of taking asthma medication was 0.20 (95% confidence interval: 0.09, 0.43) that of a participant with none/mild periodontitis. Moreover, proportion of BOP sites was statistically associated with use of asthma medication, whereas plaque index still remained non-significant. CONCLUSION: Participants with severe periodontitis were less likely to have asthma. Stronger evidence of an inverse association was found when using asthma medication as outcome.

ABSTRACT

UNLABELLED: The effects of lipid-lowering agents (LLA) on reducing systemic and oral inflammation have not been evaluated. OBJECTIVE: To assess the association of LLA use with high-sensitivity C-reactive protein (hs-CRP) and oral inflammation. DESIGN: Cross-sectional analysis using baseline data from 1300 overweight/obese participants aged 40-65 years, recruited for the ongoing San Juan Overweight Adults Longitudinal Study. Serum hs-CRP was measured by ELISA, gingival/periodontal inflammation was evaluated as bleeding upon probing (BOP), and LLA was self-reported. Separate logistic models were performed for systemic and oral inflammation. RESULTS: In all, 24% participants reported history of dyslipidaemia, of which, 50.3% self-reported LLA use. Sixty percent of the participants had elevated hs-CRP (>3 mg/dl) and 50% had high BOP (defined as at or above the median: 21%). After adjusting for age, gender, smoking, HDL-C, physical activity, diabetes, blood pressure medications, and percent body fat composition, LLA users had significantly lower odds of elevated hs-CRP compared to LLA non-users (OR = 0.58; 95% CI: 0.39-0.85). After adjusting for age, gender, smoking status, educational level, mean plaque index and percent body fat, LLA users had significantly lower odds of high BOP compared to LLA non-users (OR = 0.62; 95% CI: 0.42-0.91). CONCLUSIONS: Lipid-lowering agents may reduce both systemic and oral inflammatory responses.

ABSTRACT

CONTEXT: Periodontitis is the most common lytic disease of bone and is recognized as a common complication of diabetes. Lipid peroxidation (LPO) is increased in diabetes and may be related to modulation of the inflammatory response. LPO levels in patients with diabetes and periodontal disease have not been evaluated. OBJECTIVE: The aim of this study was to evaluate the levels of LPO and its correlation with periodontal status and inflammatory cytokines in type 2 diabetic and nondiabetic patients. DESIGN AND SETTING: This is a cross-sectional study involving Brazilian patients recruited at the State University of São Paulo. PATIENTS: The sample comprised 120 patients divided into four groups based upon diabetic and dyslipidemic status: poorly controlled diabetics with dyslipidemia, well-controlled diabetics with dyslipidemia, normoglycemic individuals with dyslipidemia, and healthy individuals. MAIN OUTCOME MEASURES: Blood analyses were carried out for fasting plasma glucose, glycated hemoglobin, and lipid profile. Periodontal examinations were performed, and gingival crevicular fluid was collected. LPO levels were evaluated by measuring oxidized low-density lipoprotein (ELISA) and malondialdehyde (HPLC). Cytokines were evaluated by the multiplex bead technique. RESULTS: LPO evaluated by malondialdehyde in plasma and gingival crevicular fluid was significantly increased in diabetes groups. Significant correlations between LPO markers and periodontal parameters indicate a direct relationship between these levels and the severity of inflammation and secretion of inflammatory cytokines, particularly in diabetic patients. CONCLUSION: These findings suggest an important association for LPO with the severity of the local inflammatory response to bacteria and the susceptibility to periodontal disease in diabetic patients.

ABSTRACT

BACKGROUND: The role of periodontal disease as an independent risk factor for cardiovascular disease (CVD) has been under debate because of the inconsistency of findings across studies. One of the major issues is the method used to assess or define periodontal disease. The present study assesses if the observed association between periodontal disease and incident myocardial infarction (MI) depends on the measurements and/or criteria used to define periodontal disease. METHODS: A population-based case-control study to evaluate the association between PD and risk of MI was conducted between 1997 and 2001 in Western New York with 537 cases and 800 controls, aged 35 to 69 years. Cases were survivors of incident MI from local hospitals in Erie and Niagara counties. Controls were randomly selected from residents of the same counties. Periodontal disease was assessed using interproximal clinical attachment loss (CAL), probing depth (PD), alveolar crest height (ACH), and number of missing teeth. From these measurements, four different case definitions of periodontal disease were created. RESULTS: Using the continuous forms of periodontal measurements, the odds ratios (ORs) (95% confidence interval) of the association with incident MI were 1.46 (1.26 to 1.69), 2.19 (1.66 to 2.89), 1.30 (1.14 to 1.49), and 1.04 (1.02 to 1.07) for mean CAL, PD, ACH, and number of missing teeth, respectively. Regardless of the case definition of periodontal disease, the estimates of the association with incident MI were statistically significant. CONCLUSIONS: The observed association between periodontal disease and incident MI was consistent across different measurements and/or case definitions of periodontal disease used. The magnitude of the association varies depending on the measurements or the criteria used to define periodontal disease.
