Demodex folliculorum 's true connection to rosacea may be linked to a distinct bacterium associated with the mites, called bacillus oleronius. in a study funded by the nrs, dr. kevin kavanagh and colleagues at the national university of ireland maynooth found that b. oleronius stimulated an inflammatory response in 79 percent of study patients. The demodex mite is beginning to be accepted as one of the triggers that stimulates tlr2 at the start of the inflammatory cascade in rosacea [5, 14, 93, 123, 173], and as a marker of rosacea : a clinical diagnosis of ppr may be confirmed by a diagnostic test based on the high demodex density present in these patients, using two sssbs taken from the same site.
Researchers examined 212 patients in three groups: healthy controls, rosacea patients without mites, and rosacea patients with mites. they found that demodex folliculorum mites were more commonly present in severe cases of papulopustular rosacea,while the other species that affects humans, demodex brevis , was found to be more common on the skin of people with milder rosacea or healthy skin. “the classic ‘subtypes’ of rosacea appear to reflect variations in inflammatory and immunologic responses which in some cases may be induced by demodex mites,” he said. “for example, in one study, individuals with erythematotelangiectatic rosacea (subtype 1) were found to have higher facial counts of demodex mites than those with papulopustular rosacea (subtype 2). Since then, multiple studies have focused on the association between demodex mites and rosacea; however, the results were inconsistent, and only a few studies attempted to establish the role of demodex mites in the pathogenesis of rosacea. recently, antiparasitic agents (eg, topical permethrin and ivermectin) have been used for treatment, based on the possible role of cutaneous demodicosis in. Are born without demodex mites on the skin [43, 54], and the mites are progressively acquired by direct contact with the skin of other humans [44, 55]. as a commensal, the demodex mite likely controls the immune system of the host, through undefined mechanisms, to ensure its own survival [8, 10, 56–60]. the delicate host demodex equilibrium may.
