Shоwn belоw is аn excerpt frоm а Februаry 2023 Healio article titled Daily kombucha intake may stabilize mast cells by Richard Gawel. Read the excerpt, then answer the questions that follow. This excerpt was edited for clarity and length. Kombucha may play a role in decreasing inflammation associated with allergic reactions, though it does not appear to do so by acting as an antihistamine, according to data presented at the American Academy of Allergy, Asthma & Immunology Annual meeting. The study followed reports of decreases in allergic reactions among patients who drank kombucha each day. Typically, kombucha is a black tea that has been fermented with a symbiotic culture of bacteria and yeast, the researchers said, adding that it has been touted for multiple health benefits including potential anti-inflammatory and immunomodulatory properties. The researchers administered standardized skin prick tests (SPTs) to three patients who were sensitized to Dermatophagoides pteronyssinus (DP) dust mites. In this case, the SPT involved using a small needle to introduce some DP allergen just beneath the surface of the skin to people who were allergic to DP. This produced an area of inflammation (called a wheal) at the site of the needle stick. Participants also had SPTs after 1 week and after 2 weeks of drinking 8 oz of kombucha each day. Next, the participants stopped drinking kombucha for 2 weeks, with additional SPTs after each week during this washout period. The researchers measured wheal size at each time point. Measurements for histamine and saline controls remained relatively consistent through the 4-week study period. However, DP wheal size decreased from a mean diameter of 9 mm down to 5 mm (a decrease of 45%) for all three patients from baseline to 1 week. Question: Come up with one possible way that kombucha may be decreasing inflammation without decreasing the amount of histamine that’s released by mast cells and basophils. Base your answer on what we learned in class about how allergies (Type I hypersensitivities) work.
