A practical and sustainable method for the synthesis of levocabastine hydrochloride (1), a H₁ receptor antagonist for the treatment of allergic conjunctivitis, that can be applied to the industrial production of the compound has been developed. Substantial improvements over the previously reported procedure are achieved via efficient preparation of an optically active key intermediate (5) without chiral resolution and with a more effective detosylation, which complements the previous procedure. Notably, our process requires no chromatographic purification and provides levocabastine hydrochloride in greater than 99...

The conjunctiva is a common site for the allergic inflammatory response due to it being highly vascularized, having constant exposure to environmental pollutants and allergenic pollens and having a unique conjunctival associated lymphoid tissue. The primary morbidity of anterior surface conjunctival disorders that include allergic conjunctivitis and tear film disorders is associated with its high frequency of involvement rather than its severity, although the more chronic forms can involve the cornea and lead to sight threatening conditions...

Household pets are well known to cause allergic symptoms in susceptible individuals, most commonly conjunctivitis, rhinitis, bronchospasm or urticaria. The increasing prevalence of exotic pets, including rodents, may introduce novel allergens into the household setting. We describe the case of a 16-year-old female who presented to the emergency department (ED) with an immediate systemic reaction consistent with anaphylaxis following a bite injury from a pet Mongolian gerbil. Although rare, gerbil bite injury represents another possible allergen source for precipitating a severe allergic reaction...

BACKGROUND: Several genetic variants have been associated with the susceptibility to allergic disease in adults, but it remains unclear whether these genetic variants are also associated with the onset of allergic disease early in life. The aim of this study was to develop a genetic risk score (GRS) for allergy based on findings in adults and study its predictive capacity for allergy in children. METHODS: A GRS was constructed based on 10 SNPs previously associated with allergies in adults...

We describe for the first time the diagnosis of Schizophyllum commune infection in a captive cheetah. Eosinophilic plasmacytic conjunctivitis was detected histopathologically in a biopsy specimen. Both a second surgical specimen and drainage fluid from a gingival mass and fistula contained fungal hyphae in giant cells with granulomatous inflammation. Allergic S. commune mycosis was suspected at this point. A monokaryotic isolate was characterized morphologically, and then identified genetically. Treatment with itraconazole and pimaricin was effective...

Seasonal allergic conjunctivitis (SAC) is a frequent disease, which is often associated with allergic rhinitis and subsequently manifested as allergic rhinoconjunctivitis. In contrast to other types of chronic allergic conjunctivitis, the course of SAC is not sight-threatening. Pathogenetically, the underlying cause of SAC is an immunoglobulin E (IgE) mediated, Th2-driven type 1 hypersensitivity reaction. Clinically it presents with itching, light-red conjunctival injection as well as chemosis that exceeds the extent of conjunctival injection...

Dysfunction of the meibomian glands alters secreted meibum quantitatively and qualitatively that can lead to damage to the ocular surface epithelium. In response to an unstable tear film cause by meibomian gland dysfunction, ocular surface epithelium is damaged and expresses inflammatory cytokines leading to secondary ocular inflammation. In turn, inflammatory disorders of the palpebral conjunctiva and lid margin may affect the structure and function of meibomian gland. The disorders include allergic conjunctivitis, long-term usage of contact lenses, dermatological diseases that affect conjunctival homeostasis, Stevens-Johnson's syndrome or chemical burning of the ocular surface and lid margin...

Atopic dermatitis (AD) is a complex condition that results from the dynamic interplay between genetic predisposition, skin barrier defects, environmental factors, and a dysfunctional immune system. As a result, AD can be complicated by irritant and allergic contact dermatitis and imbalances in the skin microbiome, which can subsequently exacerbate the severity and complicate the course of preexisting atopic disease. Itch is an important symptom of AD, as it plays a large role in the quality of life of patients and their families...
