Mast Cell Treatment for Tick-Bite Illness Symptoms
Treatments studied
Part of Immune system & allergy clinical trials.
This study tests whether medications that calm mast cells (immune cells) can reduce lingering symptoms from certain tick-borne infections. You may qualify if you had Ehrlichiosis, Rocky Mountain Spotted Fever, or alpha-gal syndrome and still have bothersome symptoms months after treatment.
Summary written for real people, not researchers, by Clin2.

This study looks at how a person’s immune system responds after exposure to Ixodes (black-legged) tick bites. It aims to better understand the body’s early immune reaction after tick exposure, using blood tests and small skin samples.
This study looks at how the body reacts to tick bites, specifically to understand alpha-gal syndrome—a condition that can cause allergic reactions to red meat. If you had a recent tick bite and can provide the tick, you may be able to help researchers learn more.
This study tests whether a steroid medication called dexamethasone can help people with tick-borne encephalitis, a serious brain infection spread by ticks. The goal is to see if this treatment reduces inflammation in the brain and improves recovery.
This trial collects blood and tissue samples to better understand allergies, asthma, and mast cell conditions. It aims to find markers that could improve diagnosis and treatment. Participation involves donating samples and sharing medical history.
This study looks at blood antibody test results in adults who may have tick-borne encephalitis and also signs of Lyme disease. It may help researchers understand how these infections relate and which lab patterns fit different illnesses.
This study tests whether a short course of a strong antibiotic (ceftriaxone) can help people who still have fatigue and other symptoms after being treated for Lyme disease. It aims to see if this treatment can improve your quality of life.
