RESUMO
@#Periodontitis is a chronic infectious disease in which periodontal tissue loss is caused by dental plaque biofilm. Atherosclerosis is a chronic inflammatory disease that occurs in the walls of arteries and is characterized by lipid accumulation. Recently, many studies have suggested that there is a certain relationship between periodontitis and atherosclerosis. From an epidemiological perspective, a previous literature review indicated that patients with periodontitis have a higher incidence of atherosclerosis. IL-17 secreted by Th17 cells may aggravate the progression of the two diseases by elevating the levels of matrix metalloproteinases, which may damage the connective tissue. Treg cells reduce the activation of T cells and limit the development of inflammation by secreting anti-inflammatory factors and expressing coinhibitory molecules. Periodontal intervention may contribute to the treatment of atherosclerosis by reducing inflammatory markers in atherosclerosis. Many studies have shown that periodontitis and atherosclerosis may interact with each other, but further studies are needed to explore the concrete mechanism of the interaction between periodontitis and atherosclerosis.
RESUMO
Objective To compare the changes of BNP and IL-1βin patients with chronic heart failure combined with chro-nic periodontitis before and after periodontal intervention treatment and investigate the improve effect of periodontal intervention treat-ment on the prognosis of chronic heart failure.Methods 38 patients with chronic heart failure combined with chronic periodontitis were divided into the intervention group (n=20) and the control group (n=18).The intervention group was given periodontal inter-vention and the control group was only given oral hygiene education .The baseline and changes of bleeding index , periodontal attach-ment loss and BNP, IL-1βof the two groups were recorded respectively.Results After periodontal treatment, the bleeding index, periodontal attachment loss and the baseline in the intervention group were significantly differenct compared with the control group (p<0.05).The changes of BNP and IL-1βindex in the intervention group were also significantly different from those of the control group (p<0.05).Conclusion The oral hygiene and periodontal health status of the patients could be improved by periodontal inter-vention.It can also improve the prognosis of patients with periodontitis combined with chronic heart failure .In conclusion, the perio-dontal intervention treatment plays a positive role in the treatment of chronic heart failure disease .
RESUMO
Objective: To determine the efficacy of periodontal intervention on pregnancy outcome in mild preeclamptic women.Methods: A sample of 60 pregnant women with mild preeclampsia (blood pressure levels <160/110 mm and proteinuria >300 mg/l in 24 hours urine) from the Hospital Universitario del Valle (Cali, Colombia) was included to the study. Preeclamptic women were randomized in two groups, one with periodontal intervention (PIG, N=28) and another in which the periodontal intervention was practiced after childbirth (NPIG, N=32). Maternal socio-demographic, medical and periodontal data were obtained. PIG included patients in which supragingival and subgingival cleaning within ultrasonic and manual devices were performed after study inclusion. The progression from mild to severe preeclampsia, eclampsia or HELLP syndrome, the number of days of clinical stability and the percentile of birth-weight adjusted for gestational age were evaluated in both groups. Results: Most of the patients (60%) were multigravids. Gestational age at inclusion was 31.8±1.6 weeks. Chronic periodontitis was a frequent finding (61.7%). Social, demographic, medical and periodontal conditions were similar between both groups. Disease progression to severe preeclampsia, eclampsia or HELLP syndrome was also similar (89.2% PIG versus 84.4%, p=0.65) (OR=1.06 IC 95% 0.87-1.29, p=0.65). Days of clinical stability were similar between the groups (median 10 days , range 1-46, PIG versus 12 days, range 1-59, p=0.57) and the percentile of birth weight adjusted with gestational age had no differences between the groups (median percentil 50 range 5-90 PIG versus percentil 55 range 5-95, p=0.73). Conclusion: Periodontal intervention does not seem to harm the health, the severity or alter the frequency on maternal complications in mild preeclampsia subjects.
Objetivo: Determinar la eficacia y seguridad de la intervención periodontal sobre el producto del embarazo en gestantes hospitalizadas con diagnóstico de pre-eclampsia sin complicaciones. Métodos: En un ensayo clínico controlado se evaluaron 60 mujeres embarazadas con diagnóstico de pre-eclampsia leve (presión arterial <160/110 mm Hg y proteinuria >300 mg/l en orina de 24 horas), que se trataron en la unidad de alto riesgo obstétrico del Hospital Universitario del Valle (Cali, Colombia). Se evaluaron las características socio-demográficas, así como los aspectos médicos y periodontales. De este conjunto 28 (46.7%) gestantes se incluyeron al azar en el grupo con intervención periodontal anteparto (GIP) y 32 (53.3%) en el grupo sin intervención periodontal (GNIP). El análisis se hizo de acuerdo con la intención de tratamiento. La variable dependiente fue la proporción de mujeres que agravaron su condición pre-eclámptica hacia pre-eclampsia severa, eclampsia o síndrome de HELLP, el número de días de estabilidad clínica y el percentil de peso del recién nacido ajustado para la edad de la gestación. Resultados: De las pacientes 60% eran multíparas. La edad gestacional promedio de ingreso al estudio fue 31.8 semanas. El diagnóstico periodontal más frecuente fue periodontitis crónica (61.7%). Las características socio-demográficas, obstétricas y periodontales fueron afines en ambos grupos. La pre-eclampsia se agravó de manera comparable en los dos grupos (GIP 89.2% versus GNIP 84.4%, p=0.65) (OR=1.06 IC 95% 0.87-1.29, p=0.65). La estabilidad clínica en días, fue parecida en ambos grupos (GIP mediana 10 días, rango 1-46 versus GNIP 12 días, rango 1-59, p=0.57). La mediana del peso del recién nacido ajustado por la edad gestacional fue semejante en los dos grupos (GIP percentil 50, rango 5-90 versus GNIP percentil 53 rango 5-95, p=0.73).
