Described in the paper are the results of examination of the local immunity in patients with demodectic blepharoconjunctivitis (DBC). Demodicosis of the eyes was established to develop in impairments of the local immunity described by a lower level of IL-4 in lacrimal fluid, a lower relative quantity of CD3+ cells, and a higher relative count of CD16+-lymphocytes infiltrating the eyelid-conjunctiva epithelium. The age-related immunodeficiency manifested as a decreased relative number of CD3+ and CD4+-lymphocytes infiltrating the eyelid-conjunctiva epithelium provokes a higher invasion of ticks and an increased morbidity of demodicosis among elderly people. DBC, when complicated by episcleritis or keratitis, is accompanied by a higher IgE level in lacrimal fluid and a decreased ratio of IgE/IL-4, which matters in prognostication and pathogenetic substantiation of DBC therapy.

An 8-year-old, neutered male, domestic shorthair cat housed at the North Carolina State University, College of Veterinary Medicine, Laboratory Animal Research facility as part of a research colony was examined because of mulifocal skin lesions. The lesions consisted of patchy alopecia with mild crusting of the periauricular region, neck, and dorsum; periauricular excoriations; marked dorsal seborrhea and scaling; and generalized erythematous papules. A moderate amount of ceruminous exudate was present in both ear canals. Results of testing for feline immunodeficiency virus (FIV) were positive. An ear swab specimen and superficial and deep skin scrapings were obtained, mounted with oil on glass slides, and coverslipped for microscopic examination. Two populations of mites were observed: a large population of slender, long (approximately 200 microm), adult mites with long, tapering abdomens that comprised two-thirds of the total body length; and a smaller population of more translucent and shorter mites (approximately 100 microm) with wide, blunt abdomens that had prominent transverse ridges. The interpretation was demodicosis, with Demodex cati and D gatoi co-infection. Histologic sections of biopsies from skin lesions on the neck, dorsum, and periauricular area contained a mild perivascular and perifollicular inflammatory infiltrate composed predominantly of histiocytes, lymphocytes, and plasma cells. Diffusely within the follicular lumina and occasionally within the superficial keratin, a myriad of Demodex organisms were observed. Intrafollicular mites were compatible in appearance with D cati whereas those in the corneal layer were suggestive of D gatoi. Demodicosis is an uncommon disease of cats, and rare cases of dual infection have been documented, occasionally in FIV-infected cats. The dual infection emphasizes the importance of doing both superficial and deep skin scrapings and of recognizing the unique microscopic features of different Demodex mites.

Amicrobial pustulosis of the folds is a chronic relapsing neutrophilic dermatosis characterized by sterile pustules compromising skin folds, scalp, face and periorificial regions. It predominantly affects women. Demodicosis is an inflammatory disease associated with cutaneous overpopulation of the mite Demodex spp., the pathogenesis of which is not completely established, but is frequently related to local immunodeficiency. A case of a young woman with amicrobial pustulosis of the folds, and isolated worsening of facial lesions, is reported; investigation revealed overlapping demodicosis. There was complete regression of lesions with acaricide and cyclin treatment. This case warns of a poorly diagnosed but disfiguring and stigmatizing disease, often associated with underlying dermatoses or inadvertent treatments on the face.
