Observational Study on Cytokine Production by Leukocytes of Papillon-Lefèvre Syndrome Patients and Healthy Probands in Whole Blood Cultures
In Brief
An observational study for Papillon-Lefevre Disease. Completed, enrolled 17 participants across 1 site.
Detailed Summary
Papillon-Lefèvre syndrome (PLS) is characterised by aggressively progressive periodontitis combined with palmo-plantar hyperkeratosis. It is caused by "loss of function" mutations in the cathepsin C gene. The hypothesis behind this study is that PLS patients' PMNs produce more proinflammatory cytokines to compensate for their reduced capacity to neutralize leukotoxin and to eliminate Aggregatibacter actinomycetemcomitans. Production of more interleukin (IL)-8 would result in the attraction of more PMNs. Thus, the aim of this study was to evaluate the cytokine profile in PLS patients' blood cultures.
