“…1 HIV infection was detected in a third of this group (5/15), reflecting the high background prevalence in the general population. Rosacea has been described in the setting of HIV infection in previous studies, 6 particularly granulomatous rosacea, and thus may explain the association. 1,7,8 Demodex infestation was not evaluated; however, it was not seen in any of the histological sections even though it has been reported in other studies of HIV-infected patients.…”

Rosacea is a chronic facial dermatosis considered to affect primarily white patients with light phototype skin, and is poorly documented in black patients. The aim of this study was to document the clinical features of rosacea in patients with phototypes V and VI. An 8-year retrospective chart review of patients with a clinical and histological diagnosis of rosacea or acne rosacea was undertaken. Of 6700 patients, 15 (0.2%) had rosacea. All were of African descent with skin phototype V or VI. Mean age was 47 years, and female : male ratio was 14 : 1. Of the 15 patients, 5 (33%) were positive for human immunodeficiency virus; 5 (33%) had used topical steroids to treat the roseacea; 6 (40%) had phototype V and presented with erythema, telangiectasia and erythematous papules, while 9 (60%) had phototype VI skin and presented with skin-coloured papules; and 10 (67%) had histology showing granulomatous rosacea, while 5 (33%) declined a facial skin biopsy. A high index of suspicion is required to diagnose rosacea in black patients as the classic signs of erythema and telangiectasia are difficult to discern.

“…In the study control group Demodex was detected in 22.9% of people. The authors suggest that these results may indicate that immunosuppression does not significantly affect the incidence of invasion (34). Research carried out in Wroclaw among patients of the Regional Hospital, students of the Medical University and patients of the Clinic of Prevention, Treatment and Therapy of Addictions for the MONAR association Youth, showed a 41% prevalence of Demodex inva- (57).…”

Mites from the genus Demodex are ectoparasites of many mammals, including humans. There are over 100 Demodex species, which demonstrate strong specificity in host selection [Table 1]. The mites are common in humans. It has been estimated that up to 60% of adults may be infected, but in most cases no symptoms of the disease are present. Demodex multiplication inside sebaceous glands and hair follicles can lead to skin disease in both humans and animals. In humans, the main problem is ocular demodecosis, which can cause chronic conjunctivitis and blepharitis. In this paper, we present the biology and epidemiology of Demodex species in humans as well as in domestic and farm animals. Characteristic lesions, diagnostics and treatment of demodecosis are also described

“…Although not common in developed countries, ascariasis invasion is increasingly likely to be encountered by clinicians because of the growing rates of travel to developing countries and increased migration. Moreover, in industrialized countries, risk groups for parasitic diseases (e.g., A. lumbricoides infection) include patients with immunodeficiency following chemotherapy and radiotherapy and AIDS [4, 5]. …”

In industrialized countries, risk groups for parasitic diseases include travelers, recent immigrants, and patients with immunodeficiency following chemotherapy and radiotherapy and AIDS. A 66-year-old Polish male was admitted in December 2012 to the Department of Haematology in a fairly good general condition. On the basis of cytological, cytochemical, immunophenotypic, and cytogenetic analysis of bone marrow, the patient was diagnosed with acute myeloblastic leukemia. On the 7th day of hospitalization in the Department of Haematology, patient was moved to the Intensive Care Unit (ICU) due to acute respiratory and circulatory failure. In March 2013, 3 months after the onset of respiratory failures, a mature form of Ascaris spp. appeared in the patient's mouth. This report highlights the importance of considering an Ascaris infection in patients with low immunity presenting no eosinophilia but pulmonary failure in the central countries of Europe.

Demodex folliculorumandDemodex brevisin healthy and immunocompromised patients

Abstract: Proportions of D. folliculorum and D. brevis, and also symptoms of blepharitis were similar in the control group and immunocompromised patients. Immunosuppression did not seem to increase the rate of Demodex spp. infection.
