Immune response was characterized with the True-culture (R) whole blood assay. Out of 30 cytokines significant increases (t-test, p< 0,05) were shown for the T-cell dependent cytokines GM-CSF, IFNgamma (p = 0,078), IL-4, IL-10, IL-17 and TNFbeta after 3 days of juice intake. The study confirmed former results of stable levels of cytokines over several weeks within the individual, while the variabilty between individuals can be high. Studies must be designed analyzed carefully to be able to characterize immune responses properly.

The analysis of cytokines (Interferon gamma, IL-2, IL-6, IL8, IL-10, IL13 and MCP-1) was performed with the TrueCulture(tm) whole-blood culture system (EDI GmbH). With a single dose of 3000 F. I. P. bromelain, IFNgamma was found to be significantly stimulated in the afternoon hours compared to placebo (p = 0.043; Mixed Linear Model, Bonferroni adjusted). N2 - In einer randomisierten, controlleirten Cross-Over-Studie wurde der Effekt einer einmaligen Appliaktion von 1000 bzw. 3000 F. I. P. Bromelain (Ursapharm GmbH, Saarbrücken)untersucht. Endpunkte waren 6 Zytokine(Interferon gamma, IL-2, IL-6, IL8, IL-10, IL13 and MCP-1), die mittels TrueCulture-Test-System (EDI-GmbH, Reutlingen) analysiert wurden. Die Analyse mittels Gemischtem Linearen Model ergab, dass die Doseriung von 3000 F.I.P. Bromelain einen signifikanten Anstieg im Vergleich zu Plazebo bewirkte (p=0,043, Bonferroni-korrigiert).

The study shows that, depending of the type of cytokine, the variability of these potent mediators of immune functions in fact be high high between subjects, but relatively small within a subject. By using appropriate statistical techniques, the use of cytokines as endpoints in investigational clinical studies has become possible. N2 - Bislang wurden Zytokine als schwierige Substanzen betrachtet, um Wirkungen auf das Immunsystem zu untersuchen. Die Studie zeigt, dass, je nach Art des Zytokins, die Unterschiede zwischen den Individuen zwar sehr groß sein können, die Variation innerhalb des Individuums jedoch etimmten Response-Korridors bleiben. Mit geeigneten statistischen Techniken kann diesem Umstand Rechnung getragen werden, so dass die Zytokine als klinische Endpunkte in klinischen Forschungsprojekten genutzt werden können.
