The increase in other medical conditions and poly-pharmacy associated with aging may detract from the relationship (Al-Zahrani et al generic clonidine 0.1mg overnight delivery heart attack zippo. Obesity is associated with various health related choices that impact periodontal status (e buy cheap clonidine 0.1mg line blood pressure chart heart.org. The association between obesity and periodontal disease has also been shown to be independent of type 2 diabetic status (Saito et al. Although obesity in itself has been independently associated with periodontitis risk, a model linking obesity, diabetes and periodontal disease has been recognized. Only Tannerella forsythia was found in elevated levels in the biofilm of obese individuals with healthy periodontal tissues or gingivitis. This may reflect an overgrowth of this organism that might increase initiation and progression of periodontitis. This study demonstrates the 47 impact of obesity on systemic inflammation and need for not only periodontal intervention but also obesity counseling to reduce cardiovascular risk. The potential observational evidence for obesity to increase the risk for periodontitis, another chronic inflammatory disease has been discussed above. The proposed mechanisms underlying this association are not fully elucidated at present but some lines of evidence exist relating the pathogenesis of these diseases. From early animal experiments it was shown that obese rats were more likely to develop periodontitis than normal rats (Perlstein et al. Obesity is commonly associated high circulating free fatty acids levels which have been shown to directly cause proliferation of the junctional epithelium and bone loss in rat periodontitis lesions (Tomofuji et al. As mentioned earlier, adipose tissue, especially visceral adipose tissue, is an important organ that produces several systemically active substances known as adipocytokines. One study analyzed 49 gingival crevicular fluid levels of tumor necrosis factor-α in young subjects (Lundin et al. Some studies have hypothesized that the association of obesity with periodontitis is inextricably linked with insulin resistance and diabetes. It is hypothesized that this priming of the inflammatory response that causes the immune system to exhibit an exaggerated immune reaction to periodontal pathogens. As already mentioned there is evidence for the independent association of obesity with periodontitis (Saito et al. Proinflammatory cytokines play essential roles in the inflammatory reaction in periodontal disease. The adiopkine leptin stimulates the immune system by increasing cytokine production and phagocytosis by macrophages and increasing oxidative stress (Fantuzzi et 50 al. In obesity leptin upregulates adhesion molecules on endothelial cells, leading to transmigration of monocytes and therefore increased numbers of macrophages. Although reports consistently point to an association between obesity and periodontitis, more longitudinal randomized controlled studies are necessary to further elucidate the complex role of obesity in periodontitis. However, due to increased risks for diseases associated with obesity and the potential impact on periodontal tissues, counseling on obesity is recommended as an important component of patient management in the periodontal office. Management and education of obese patients may necessitate provision of nutritional information which may also impact periodontal health (Chapple, 2009). As already discussed research has shown that obesity can be significantly associated with increased risk of systemic (Kopelman et al. However, until recently interest on the effects of nutrition in the periodontal literature has been minimal. Revival of interest in the association between periodontitis and malnutrition has been largely mitigated through the early hypothesis that deficiencies in certain micronutrients may lead to increased oxidative stress and a decrease in the body’s ability to combat infection. A significant association between poor overall diet quality and higher periodontitis prevalence has been recently reported (Al-Zahrani et al. Due to the multifactorial etiology of the disease, it can be difficult to find direct associations between risk factors and periodontitis. Problems are further increased with a potential risk factor like nutrition due to conflicting opinions on what constitutes an appropriate balanced diet, the use of self-reported diet analysis in epidemiological studies and complications in assessing micronutrient deficiencies among individuals. These issues were present in earlier studies, which reported conflicting results regarding 52 associations between several individual micronutrients and prevalence of periodontitis (Slade et al.

Two clinical studies examined the relative inhibitory action of quercetin vs grapefruit juice on nifedipine pharmacokinetics (338) and narin- gen vs grapefruit juice on felodipine pharmacokinetics (339) 0.1mg clonidine heart attack youtube. Neither flavoniod when administered at doses comparable to those in the grapefruit juice caused any effect on the bioavailability of the drug (338 buy cheap clonidine 0.1mg line blood pressure 2,339). Their inhibitory capacity for 3A4-related substrates was one to two orders of magnitude greater than the flavonoids (Fig. The relative potency of components of grapefruit juice to inhibit P450 3A4 activities. The data for the flavonoids are for nifedipine oxidation and are from Guengerich and Kim (333). With only limited amounts of the furanocoumarins available, there has not yet been a clinical study to indicate they can substitute for grapefruit juice in causing drug inter- actions. Their role in grapefruit juice drug interactions therefore has not yet been established. Grapefruit juice also effects P-glycoprotein-mediated transport, increas- ing the basolateral to apical flux (337,346,347). The relative role the transporter and P450 3A4 have on the bioavailability of a drug may also be important in determining the active component in the effect of grapefruit juice. For benzodiazepines undergoing oxidative metabolism, P450 3A4 appears to be more important. In normal subjects, the effect was modest, and accompanied with no or only minor effects on the pharmacodynamics of the benzodiazepines (348,350–352). This suggests that cirrhotics are more dependent upon intestinal metabolism of midazolam. In a study on other juices, tangerine juice was found to delay the absoprtion of midazolam and slightly delay its pharmacodynamic effects (353; Table 29). Interactions with Miscellaneous Agents Clinical studies concerning potential drug interactions with benzodiazepines have been performed with a number of drugs for which either only a single drug in its class was studied, or there was no explicit connection with an aspect of drug metabolism. It did produce a significant decrease in the pharmacodynamic measures of diazepam (354; Table 30). The effect of chronic theophylline on alprazolam was compared in subjects with chronic obstructive pul- monary disease that were or were not taking theophylline. Caffeine was found to have no effect on the pharmacokinetics of diazepam (356) or alprazolam (203); but caffeine did slightly diminsh the pharmaco- dynamic measures for diazepam (356; Table 30). Chronic disulfiram treatment was found to diminsh the elimination of chlordiazepoxide and diazepam, but not that of oxazepam in normal subjects (Table 30). The clearance and t1/2 of the three benzodiazepines in chronic alcoholics who had received chronic disul- firam treatment were similar to those in the disulfirma-treated normal subjects (358). In a study with 11 chronic alcoholics, alprazolam was given prior to initiation of disul- firam treatment and again after 2 wk of disulfiram; no change in the pharmacokinetics of alprazolam was noted (359). Like oxaze- pam it is primarily elimated after glucuronidation, and both are highly protein bound. When oxazepam was given before and after 7 d of 2/d treatment with diflunisal, the Cmax of oxazepam was decreased and its oral clearance increased. The authors conclude that the interaction resulted from the displacement of oxazepam from its protein-binding sites and by inhibition of the tubu- lar secretion of the oxazepam glucuronide. The authors concluded that these find- ings were consistent with the induction of P450 and/or glucuronidation (360). Five daily “small” doses of dexamethasone were found to have no significant effect on the pharma- cokinetics or pharmacodynamics of triazolam in normal volunteers (361; Table 30). The authors did detect a significant decrease in the percentage of diazepam plus metab- olites excreted in urine over a 96-h period (362). The findings suggest that paracetamol may decrease the glucuronidation of diazepam metabolites. The effect of probenecid on the elimination of benzodiazepines was first studied 1.
