agreement rate of rapid urease test conventional pcr and scorpion real time pcr in detecting helicobacter pylori from tonsillar samples of patients with Chronic Tonsillitis
Journal of Global Infectious Diseases, 2012Co-Authors: Reza Najafipour, Taghi Naserpour Farivar, Ali Akbar Pahlevan, Pouran Johari, Farshid Safdarian, Mina AsefzadehAbstract:Background: Helicobacter pylori is capable of inducing systemic inflammatory reactions through immunological processes. There are several methods to identify the presence of H. pylori in clinical samples including rapid urease test (RUT), conventional polymerase chain reaction (PCR), and the Scorpion real-time PCR. Aim: The aim of the present study is to compare the agreement rate of these tests in identifying H. pylori in tonsillar biopsy specimens collected from patients with Chronic Tonsillitis. Materials and Methods: A total of 103 tonsil biopsy samples from patients with clinical signs of Chronic Tonsillitis were examined with RUT, PCR, and Scorpion real-time PCR. The degree of agreement between the three tests was later calculated. Results: There was a poor degree of agreement between RUT and PCR and also RUT and Scorpion real-time PCR (Kappa=0.269 and 0.249, respectively). In contrast with RUT, there was a strong degree of agreement between PCR and Scorpion real-time PCR (Kappa=0.970). Conclusion: The presence of a strong agreement between the Scorpion real-time PCR and PCR as well as its technical advantage over the conventional PCR assay, made the Scorpion real-time PCR an appropriate laboratory test to investigate the presence of H. pylori in tonsillar biopsy specimens in patients suffering from Chronic Tonsillitis.

simultaneous clonally identical t cell expansion in tonsil and synovium in a patient with rheumatoid arthritis and Chronic Tonsillitis
Arthritis & Rheumatism, 2003Co-Authors: Mitsuhiro Kawano, Kanae Okada, Hiroaki Muramoto, Hajime Morishita, Takayo Omura, Ryo Inoue, Susumu Kitajima, Kenichi Katano, Ichiro Koni, Hiroshi MabuchiAbstract:In some patients with rheumatoid arthritis (RA), the disease improves following tonsillectomy. We describe a 28-year-old woman with treatment-resistant RA and Chronic Tonsillitis. Initially, her arthritis had been well controlled with methotrexate and corticosteroids, but the RA activity became difficult to control in spite of addition of bucillamine to the treatment regimen and repeated arthrocentesis with infusion of corticosteroid into her swollen joints. Closer examination revealed that the period of exacerbation of her Chronic Tonsillitis paralleled that of the systemic arthritis, and administration of antibiotics brought transient relief of the systemic symptoms. Her arthritis was ameliorated after successful tonsillectomy and synovectomy, with marked reduction of the serum rheumatoid factor concentration. Analysis of infiltrating T cell clones in tonsil and synovium using T cell receptor V(beta) repertoire and third complementarity-determining region size distribution analysis followed by nucleotide sequencing revealed common clonal T cell expansion in both tissues. This finding suggests the possible involvement of Chronic focal infection in refractory RA.
