Prof. M.D. Feyzullah Çetinkaya

Our 8-year-old son, a competitive junior swimmer, developed mysterious hives and wheezing only during intense training. Multiple allergists dismissed it as exercise-induced asthma. Dr. Çetinkaya was the first to suspect a rare aquagenic urticaria triggered by pool chemicals combined with physical exertion. He designed a unique pre-swim immunotherapy protocol and collaborated with our sports coach. Our son now swims at national level competitions without a single episode, thanks to this groundbreaking sports-immunology approach.

After adopting our daughter from an orphanage at age 3, she suffered 23 consecutive respiratory infections in 18 months. Conventional tests showed 'normal immunity.' Dr. Çetinkaya discovered she had a specific antibody deficiency against encapsulated bacteria due to early institutionalization. His tailored subcutaneous immunoglobulin therapy, combined with a microbiome restoration plan using specific probiotics, transformed her health. She's now infection-free for two years and thriving in kindergarten.

Our newborn developed a catastrophic inflammatory response after his first routine vaccinations—high fever, seizures, and multi-organ involvement. In the ICU, Dr. Çetinkaya diagnosed a previously unknown innate immune error in the NLRP3 pathway. He created a personalized vaccination schedule using fractional doses with pre-medication, allowing our son to develop protection without dangerous reactions. He's now a healthy toddler with complete immunization coverage.

As a 16-year-old aspiring chef, I developed severe contact reactions to garlic and onions—essential ingredients in my family's restaurant. Standard allergy tests were negative. Dr. Çetinkaya identified it as a non-IgE mediated mast cell activation disorder triggered by allicin compounds. He designed a desensitization protocol using micro-exposures during specific circadian times when my mast cells were least reactive. I can now handle all ingredients and am pursuing culinary school.
