What researchers measure

Primary outcomes

  1. Comparison of Th2 Cytokines (IL-13) Between Placebo and Probiotic Groups at Baseline (Beginning of Product Intake), 4 Weeks (Mid Period of Product Intake) and 8 Weeks (End of Product Intake)

    A maximum of 10 ml heparinized, venous blood will be collected during Visit 1, 2 and 3. Whole blood cells will be cultured for 120 hours (5 days) with culture medium with different stimuli. Cell supernatants will be collected and analyzed for different cytokines.

    Time frame: 0 (baseline), 1 and 2 months

  2. Comparison of Th2 Cytokines (IL-5) Between Placebo and Probiotic Groups at Baseline (Beginning of Product Intake), 4 Weeks (Mid Period of Product Intake) and 8 Weeks (End of Product Intake)

    A maximum of 10 ml heparinized, venous blood will be collected during Visit 1, 2 and 3. Whole blood cells will be cultured for 120 hours (5 days) with culture medium with different stimuli. Cell supernatants will be collected and analyzed for different cytokines.

    Time frame: 0 (baseline), 1, and 2 months

Secondary outcomes

  1. Comparison Between Probiotic and Placebo at Baseline (Beginning of Product Intake), 1 Month and 2 Months (End of Product Intake)

    TNSS Questionnaire were distributed at every visit (1 questionnaire for every week). The scored questionnaire were collected at subsequent visits. The symptom scores for nasal congestion, runny nose, nasal itching and sneezing were expressed as weekly sums (scale 0-3 for each symptom). The TNSS was the weekly sum for all the symptoms (scale 0-12). The TNSS data were analyzed as both monthly averages (at V2 and V3 compared to baseline V1) and weekly TNSS scores. Monthly TNSS scores were calculated as average over the 4 weeks preceding the visits. The higher the score is, the worse the outcome is.

    Time frame: Measures at baseline, 1, and 2 months

  2. Change From Baseline in Pro-inflammatory Cytokines (TNF-alpha, IL-1beta) at 8 Weeks in ex Vivo Stimulated Whole Blood Cells

    Time frame: 8 weeks

  3. Change From Baseline in Immunoglobulin Levels in Serum Between Treatment Groups

    Time frame: 8 weeks

  4. Change From Baseline in Basophil Activation at 8 Weeks in ex Vivo Stimulated Whole Blood Cells

    Time frame: 8 weeks

Participant flow

Recruitment at the Metabolic Unit, (study no. 11.03.MET, NCT01660698) during the Grass Pollen (GP) season. Twenty seven adults volunteered, of which twenty four who gave written informed consent were screened for clinical history of allergy to GP \> 2 years and a confirmatory skin prick test (SPT) to GP. Twenty subjects were randomized.
