Atopic dermatitis predisposes to skin infections, and on the other hand, some therapies used for atopic dermatitis may worsen viral infections whose lesions may be more diffuse and resistant to treatment. The authors present a patient with severe atopic dermatitis and disseminated molluscum contagiosum infection. The molluscum contagiosum did not clear with topical treatment, and it worsened her atopic dermatitis even more, so the authors started treatment with dupilumab. After two months, the patient's dermatitis went into clinical remission and there was resolution of the infection with no recurrence at the 12-month follow-up. Dupilumab is nowadays a promising treatment for severe atopic dermatitis. To our knowledge, only four reports of molluscum contagiosum during dupilumab therapy have been reported in the literature, with contrasting effects. According to the authors' experience, treatment with dupilumab appears to be a safe alternative for patients with severe atopic dermatitis who are also infected with molluscum contagiosum, as opposed to other treatments such as systemic corticosteroids or cyclosporine.
Macrophages are versatile myeloid leukocytes with flexible cellular states to perform diverse tissue functions beyond immunity. This plasticity is however often hijacked by diseases to promote pathology. Scanning kinetics of macrophage states by single-cell transcriptomics and flow cytometry, we observed atopic dermatitis drastically exhausted a resident subtype S1.
The connection between the immune response and the composition of gut microbiota has been associated with an increased prevalence of atopic dermatitis in the first year of life. The study aimed to investigate gut microbiota characteristics in infants with atopic dermatitis compared to healthy infants to better understand the link between early-life microbiota composition and the development of atopic dermatitis. The study analyzed the intestinal microbiota of 121 infants with clinical signs of atopic dermatitis, divided into Group I (infants with atopic dermatitis) and Group II (healthy controls).
Mast cell-mediated reactions promote various allergic disease, including anaphylaxis, allergic rhinitis, asthma, and atopic dermatitis. Different data demonstrated an intricate relationship between the use of antihistaminic drugs, the onset of side effects, and the development of resistance, underscoring the importance to find novel therapeutic approaches to treat allergic diseases. Olive leaf extract (OLE), is a by-product of the olive tree rich in bioactive compounds, known for its numerous therapeutic properties, including antioxidant, anti-tumoral and antidiabetic effects.
