Eosinophilic esophagitis is a T-cell-driven allergic condition hallmarked by eosinophil infiltration of the esophagus. Eosinophils exposed to proliferating T cells release galectin-10 and have T-cell suppressive function in vitro. The aims of this study were to evaluate if eosinophils co-localize with T cells and release galectin-10 in the esophagus of patients with eosinophilic esophagitis.

Thymic eosinophils are often positioned in the corticomedullary junction between the CD4 CD8 double-positive (DP) thymocytes and the CD4 or CD8 single-positive (SP) thymocytes. The aims of this study were to (1) determine if there are distinct thymic eosinophil populations that differ from the blood eosinophil populations and (2) evaluate the capacity of thymic eosinophils to promote the development of SP thymocytes from DP thymocytes.

Serum IgA and IgG to SARS-CoV-2, T-cell proliferation and cytokine secretion, demographic and clinical data, PCR-verified infection, and self-reported symptoms were monitored. The multivariate method OPLS-DA was used to identify immune response patterns coupled to protection from Covid-19.

Methods: Ninety-seven Swedish adult patients with EoE and 97 controls without dysphagia filled out the S-WDS, the Swedish Eosinophilic Esophagitis Activity Index (S-EEsAI) and a set of supplementary questions.
Increased number of eosinophils in the uterus has been reported under physiological and pathologic conditions. However, eosinophilic infiltration limited to the myometrium is very unusual. A rare finding of isolated eosinophilic infiltration in the myometrium without involvement of endometrium or pathologies in the cervix or ovaries was observed in a 31-yr-old woman seeking medical attention for unexplained infertility, abnormal uterine bleeding, and dysmenorrhea.

Aims: Our aim was to determine whether a blood-based biomarker panel centered on immune parameters could identify histologic response to treatment in eosinophilic esophagitis patients.
Methods: A pilot study involving adult patients with active eosinophilic esophagitis recruited at two Ear, Nose, Throat clinics in Sweden was designed.
