Cytokine profile in the gingival crevicular fluid of rheumatoid arthritis patients with chronic periodontitis

The aim was to assess the cytokine profile in the gingival crevicular fluid (GCF) of rheumatoid arthritis (RA) patients with chronic periodontitis (CP). Databases were searched from 1991 to August 2013 using a combination of various keywords. Eight studies were included. The GCF concentrations of interleukin (IL)‐1β, IL‐4, IL‐10, matrix metalloproteinase (MMP)‐8, MMP‐13 and tumor necrosis factor‐alpha (TNF‐α) were reported to be higher in patients with RA than in healthy controls (HC) without CP. In one study, TNF‐α levels in GCF were significantly higher in HC than in RA patients receiving anti‐TNF‐α therapy. One study reported no significant difference in GCF TNF‐α levels among RA patients and HC regardless of anti‐TNF‐α therapy. One study reported no difference in IL‐1β and prostaglandin E₂ levels among RA patients and HC with CP. Raised levels of proinflammatory cytokines are exhibited in the GCF of RA patients with CP.     

Phylloquinone in gingival crevicular fluid in adult periodontitis

Abstract. Phylloquinone is a lipid soluble vitamin which is an absolute growth requirement for black-pigmented anaerobes, many of which are implicated in the aetiology of periodontal diseases. This cross-sectional study aimed to detect the levels of phylloquinone in GCF from healthy and diseased sites in subjects with adult periodontitis, in order to investigate further its potential role in the disease process. The sample consisted of eighteen patients with adult periodontitis. Periodontal probing depths, attachment levels and gingival indices were recorded from one healthy and one diseased site in each subject. GCF was sampled and the amount of phylloquinone in each sample was determined using reverse-phase high performance liquid chromatography coupled to electrochemical detection. The mean amount of phylloquinone in accumulated GCF from diseased sites was 406 pg/site and 80 pg/site from healthy sites ( p =0.013). When the amounts of phylloquinone in GCF were expressed as concentrations the values were 228 ng/ml and 3350 ng/ml for diseased and healthy sites respectively ( p =0.084). These findings suggest the levels of phylloquinone in GCF differs in periodontal health and disease in subjects with adult periodontitis. The total phylloquinone at diseased sites may provide the nutritional requirements favouring the growth of black-pigmented anaerobes.

Accumulation of methylglyoxal in the gingival crevicular fluid of chronic periodontitis patients

BACKGROUND, AIMS: Methylglyoxal (MG), a toxic product of cellular metabolism, is elevated in tissues and fluids in a number of human diseases. A cross-sectional study was undertaken to determine whether MG accumulates in the gingival crevicular fluid (GCF) of chronic periodontitis patients. METHODS: GCF samples were collected for 30 s each from three teeth with pocket depths greater than 3 mm (DD sites), from 14 chronic periodontitis patients. Control samples were taken from three healthy sites (DH sites) in the same patients, as well as from seven subjects who were periodontally healthy (HH sites). Fluid volumes were determined and the strips were placed in 0.5 N perchloric acid. Subsequently, samples were derivatized with o-phenylenediamine and the resulting methylquinoxaline was assayed by high-performance liquid chromatography on Lichrospher(R)-100 RP-18, with UV detection. RESULTS: Mean pocket depths were 5.7+/-0.7, 2.7+/-0.6 and 2.7+/-0.5 mm (mean+/-SD) for the DD, DH and HH sites, respectively. Mean MG levels were found to be 208.7+/-241.7 and 142.9+/-235.7 pmol/site in the GCF from DD and DH sites, respectively (p=0.0023), but only 11.5+/-4.4 pmol/site for the HH sites. Bacteroides forsythus has been found to accumulate high levels of MG in culture (unpublished data) and, consistent with this, the sampled diseased sites contained higher levels of B. forsythus than the corresponding healthy sites (2.7+/-4.2 x 10(5) versus 0.7+/-1.1 x 10(5), respectively; p=0.022). Total "red complex" microorganisms were significantly elevated in the DD sites. CONCLUSIONS: In view of the known protein- and DNA-modifying effects of MG, the finding of elevated levels of MG in the GCF from chronic periodontitis patients supports the hypothesis that MG may contribute to destructive tissue damage in this disease.     

Gingival crevicular fluid glycosaminoglycan levels in patients with chronic adult periodontitis

Abstract This study investigated levels of hyaluronan and chondroitin-4-sulphate in the crevicular fluid of patients with chronic adult periodontitis at diseased and healthy sites before and after treatment. The relationship between clinical diagnostic parameters and levels of glycosaminoglycans in gingival crevicular fluid were also analysed. Within each patient. 4 sites either mesial or distal and on single rooted teeth were classified as diseased or healthy using a modified gingival index, pocket depth and attachment loss. Crevicular fluid was collected from each site using glass micropipettes and analysed for glycosaminoglycan content by cellulose acetate electrophoresis. Significantly higher levels of chondroitin-4-sulphate were detected at diseased sites prior to treatment correlating with increased pocket depth or attachment levels. Following a period of treatment consisting of oral hygiene instruction and root planing, the patients were reassessed for their response to treatment by measuring the modified gingival index, pocket depth, attachment loss and levels of glycosaminoglycans. Analysis of glycosaminoglycan levels at diseased sites that demonstrated a poor response to treatment also demonstrated significantly higher levels of chondroitin-4-sulphate than those sites that responded well to treatment. Hyaluronan levels were less significantly associated with clinically succesful treatment. This study confirmed the use of the sulphated glycosaminoglycan chondroitin-4–sulphate as a potential diagnostic aid of periodontal tissue destruction; however, further longitudinal studies are required to assess their performance.
