Patients visiting National Hospital of Odonto-Stomatology for treating periodontitis used a food supplement (lozenge) containing chicken egg antibody (IgY) against Porphyromonas gingivalis gingipains as an adjunct to conventional scaling and root planing (SRP). After 8 weeks the patients were examined against. Parameters including probing depth (PD), bleeding on probing (BOP), number of P. gingivalis in periodontal pockets were evaluated and compared to the control group that had used placebo lozenges.

H. pylori positive patient volunteers that passed the selection criteria are recruited and divided into a test and a control group. Both groups are treated with a current treatment regime (EAC: Esomeprazole 40 mg/day; Clarithromycin 1000 mg/day; Amoxicillin 2000 mg/day) but only the test group received IgY-containing food supplement as an adjunctive measure for 15 days. The subjects are examined before and 4 weeks after the treatment initiation by Urea Breath Test (UBT) and gastro-endoscopy.
