a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...

background: allergic rhinitis is one of the most common forms of allergic disorders affecting children. the prevalence rate of allergic rhinitis differs among countries and even among regions within the same country.   objectives: to determine the prevalence of childhood allergic rhinitis and the presence and significance of eosinophilia in nasal secretions.   method: 4584 children aged 11-15 y...

introduction: there is no single test as a gold standard for the diagnosis of allergic rhinitis (ar). the aim of this study was to assess the usefulness and validity of nasal smear as a quick, easy and inexpensive diagnostic method for diagnosis of allergic rhinitis. materials and methods: this study was conducted in a university hospital setting. nasal smears were taken from 39 patients with a...

BACKGROUND Although drug-induced peripheral eosinophilia complicates antimicrobial therapy, little is known about its frequency and implications. OBJECTIVE We aimed to determine the frequency and predictors of antibiotic-induced eosinophilia and subsequent hypersensitivity reactions (HSRs). METHODS We evaluated a prospective cohort of former inpatients receiving intravenous antibiotic thera...

Background Eosinophilia is common in patients with atopic dermatitis (AD). Abrocitinib, an oral Janus kinase-1 inhibitor and dupilumab, anti–interleukin-4 receptor-α antibody, are approved for moderate-to-severe AD. Dupilumab has been associated transient eosinophilia. Objectives To assess the effect of abrocitinib dupilumab on eosinophils from phase 3 JADE COMPARE (NCT03720470) EXTEND (NCT0342...

OBJECTIVES To determine the prevalence of eosinophilia in patients with recent-onset arthritis suggestive of rheumatoid arthritis (RA) and to describe their features and outcomes. METHODS We performed an ancillary study of data from a French prospective multicentre cohort study monitoring clinical, laboratory and radiographic data in patients with inflammatory arthritis of 6 weeks to 6 months...

Biologics used in the treatment of rheumatoid arthritis (RA) rarely cause eosinophilia. We herein report a patient with RA being treated with infliximab, adalimumab, and tocilizumab who developed eosinophilia with skin symptoms. Interestingly, the marked eosinophilia and skin symptoms did not reappear after the patient's medication was switched to golimumab. In this case, the presence of biolog...

In 1932, Loffler described a syndrome of self-limiting, transient pulmonary infiltrates associated with peripheral blood eosinophilia and mild pulmonary symptoms. A number of conditions are related to pulmonary eosinophilia or pulmonary infiltration with eosinophilia. Especially, parasitic infestations are often related to pulmonary eosinophilia, but only two cases associated with Clonorchis si...

In BALB/c mice, sensitization with the attachment protein (G) of respiratory syncytial virus (RSV) leads to CD4+ T cell-mediated lung eosinophilia during subsequent challenge with RSV. To determine the host genetic influences on this model of lung eosinophilia, we tested 15 different inbred mouse strains. Eosinophilia developed in all H-2d (BALB/c, DBA/2n, and B10.D2), but not in H-2k (CBA/Ca, ...
