[Pathophysiological analysis of rapidly progressive periodontitis].

[Article in Japanese]


Pathophysiological features were studied on 7 patients with rapidly progressive periodontitis but without any evidence of systemic disease, to analyse the clinical pathogenesis. The patients consisted of 5 females, 2 males, between the ages of 32 and 42 years. All patients had severe and rapid alveolar bone destruction on the basis of radiographic measurement. Abnormal serum levels of IgG and IgM were detected in some patients. Higher IgG level was found in 4 patients and higher IgM level was found in 2 patients. The proportion of lymphocyte subsets was calculated in mononuclear cells from peripheral blood of patients. Higher OKT4/OKT8 ratio was found in all patients. The percentage of OKT4 positive cells in 2 patients was higher than that in normal subjects while the percentage of OKT8 positive cells in 4 patients was lower than that in the healthy controls. Microorganisms from periodontal pockets were examined in 5 patients. Bacteriodes was isolated in all 5 patients and Haemophilus actinomycetemcomitans in 2 patients.
