Severe periodontal destruction in a patient with advanced anemia: A case report

Anemia is a worldwide health problem that manifests in different types. This illness has some causes, which affect body health generally. Studies have shown that some anemia types make humans more sensitive to infections

Gingival tissue human beta-defensin levels in relation to infection and inflammation.

Aim To profile gingival tissue levels of human beta-defensin (hBD)-2 and hBD-3 in relation to gingival inflammation, Th17-related cytokine concentrations, Porphyromonas gingivalis counts, and gingipain and total protease activities. Materials and Methods Gingival tissue and subgingival plaque samples were collected from 21 periodontitis patients including 48 periodontal pocket sites with marginal, mild, or moderate to severe inflammation. hBD levels were determined by immunodetection, P. gingivalis counts with real-time polymerase chain reaction, protease activities with fluorogenic substrates, and cytokine concentrations with Luminex technique. Data were statistically analysed using Kruskal-Wallis and Mann-Whitney U tests and Spearman correlation coefficients. Results Subgingival plaque counts of P. gingivalis (p = .001) and gingipain activity (p <.001), as well as interleukin (IL)-1 beta (p = .012), IL-10 (p = .024), IL-17A (p = .002), IL-17F (p = .006), and IL-23 (p = .036) concentrations were elevated in severely inflamed sites, whereas no change was observed in hBD-2 and hBD-3 levels. Negative correlations were found between protease activity and hBD-2 (p = .033) and hBD-3(p = .003) levels. Conclusions Shift in gingival inflammation from marginal to mild stage is related to elevations in subgingival plaque P. gingivalis counts and gingipain activity, but not to tissue hBD levels. Negative correlations between hBDs and total protease activity suggest the degradation of these antimicrobial peptides in progressed inflammation.Peer reviewe

Resolution Of Anterior Scleritis After Periodontal Therapy

Scleritis is a chronic inflammation that involves the outermost coat and the skeleton of the eye. Scleritis may be associated with a systemic or immune mediated disease and it might be caused by an infection, trauma or drug reaction. This case presents a patient with generalized chronic periodontitis and anterior diffuse scleritis. A 30-year-old female complained of pain and persistent scleritis in the left eye was referred to the Periodontology department due to her periodontal problems. She was treated with oral non steroidal anti-inflammatory drugs and topical medications (corticosteroid) for her scleritis during last two years. However, these treatments failed to control the progression of the disease. After periodontal examination, deep periodontal pockets and serious bone loss was detected radiographically. She was treated by flap procedures and 3 teeth were extracted. After a 4-month healing period, scleritis was resulted in rapid resolution.PubMe

Localization and expression profiles of gingival monocyte chemoattractant protein-1-induced protein-1 (MCPIP-1) and mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1)

Objectives The purposes of this study were to localize monocyte chemoattractant protein-1-induced protein-1 (MCPIP-1) and its suppressor mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT-1) in gingival tissues and to profile their protein expression levels in relation to the clinical inflammation, Porphyromonas gingivalis colonization, and interleukin (IL)-8 levels.Materials and methods Study samples were collected from two independent study populations: (1) Gingival tissues were collected from eight periodontally healthy individuals and eight periodontitis patients to localize MCPIP-1 and MALT-1 immunohistochemically, and (2) forty-one gingival tissue samples with marginal, mild, or moderate to severe inflammation were collected from 20 periodontitis patients to determine MCPIP-1 and MALT-1 levels using immunoblots, P. gingivalis levels with qPCR, P. gingivalis gingipain activities with fluorogenic substrates, and IL-8 levels with multiplex technique.Results MCPIP-1 was detectable in the epithelium and in connective tissue, being especially prominent around the blood vessel walls in healthy periodontal tissues. MALT-1 was observed at all layers of gingival epithelium and especially around the accumulated inflammatory cells in connective tissue. No difference in gingival tissue MCPIP-1 and MALT-1 levels was observed in relation to the severity of gingival inflammation. MALT-1 levels were elevated (p = 0.023) with the increase in tissue P. gingivalis levels, and there was an association between MALT-1 and IL-8 levels (beta = 0.054, p = 0.001).Conclusions Interactions of MALT-1 levels with gingival tissue P. gingivalis counts and IL- 8 levels suggest that activation of MALT-1 can take part in P. gingivalis-regulated host immune responses.Peer reviewe
