Chronic hepatitis C virus (HCV) infection is associated with various extrahepatic manifestations, including dermatologic involvement mostly caused by immune complexes. Mixed cryoglobulinemia has a strong relationship with HCV with 95% of these patients being infected with HCV. Lichen planus is a disease of the squamous epithelium and may affect any part of the skin, with 4% to 24% of patients with lichen planus reported to have chronic HCV infection. Read More

New all-oral direct-acting antivirals (DAA) have changed the hepatitis C virus (HCV) treatment landscape. Given that dermatologists frequently encounter HCV-infected patients, knowledge of the current treatment options and their utility in treating HCV-associated dermatologic disorders is important. In addition to highlighting the new treatment options, we review four classically HCV-associated dermatologic disorders - mixed cryoglobulinaemia (MC), lichen planus (LP), porphyria cutanea tarda (PCT) and necrolytic acral erythema (NAE) - and examine the role for all-oral direct-acting antiviral (DAA) regimens in their treatment.

Viruses are considered intracellular obligates with a nucleic acid RNA or DNA. They have the ability to encode proteins involved in viral replication and production of the protective coat within the host cells but require host cell ribosomes and mitochondria for translation. The members of the families Herpesviridae, Poxviridae, Papovaviridae, and Picornaviridae are the most commonly known agents for cutaneous viral diseases, but other virus families, such as Adenoviridae, Togaviridae, Parvoviridae, Paramyxoviridae, Flaviviridae, and Hepadnaviridae, can also infect the skin.

Of all tissues, the skin has the third highest abundance of zinc in the body. In the skin, the zinc concentration is higher in the epidermis than in the dermis, owing to a zinc requirement for the active proliferation and differentiation of epidermal keratinocytes. Here we review the dynamics and functions of zinc in the skin as well as skin disorders associated with zinc deficiency, zinc finger domain-containing proteins, and zinc transporters. Read More

The association of chronic hepatitis C virus (HCV) infection with a wide spectrum of cutaneous manifestations has been widely reported in the literature, with varying strength of epidemiological association. Skin diseases which are certainly related with chronic HCV infection due to a strong epidemiological and pathogenetic association are mixed cryoglobulinemia, lichen planus and porphyria cutanea tarda. Chronic pruritus and necrolytic acral erythema are conditions that may share a possible association with HCV infection, while several immune-mediated inflammatory skin conditions, such as psoriasis, chronic urticaria and vitiligo, have been only anecdotally reported in the setting of chronic HCV infection.

Background: We are reporting a series of interesting cases, which presented to us with psoriasiform lesions distributed over the acral regions of the body. The cases are unusual because they were resistant to conventional treatment modalities like topical corticosteroids, tacrolimus and oral methotrexate but showed significant improvement on oral zinc therapy.

Materials And Methods: Ten patients with characteristic clinical features of distinctive hyperkeratotic plaque in the acral areas, who were resistant to treatment by different modalities including potent topical steroids and oral methotrexate, were included for detailed investigations. Read More

In 1996 el Darouti and Abu el Ela described seven Egyptian patients with similar cutaneous lesions and proposed necrolytic acral erythema (NAE) as a distinct entity of the necrolytic erythema family. Since then, NAE has emerged as a cutaneous manifestation of hepatitis C virus infection and taken its place in the literature as a marker for systemic disease. NAE initially presents with burning, pruritic eruptions of circumscribed, erythematous papules with flaccid vesiculation on the acral surfaces universally affecting the dorsum of the feet. Read More

Necrolytic acral erythema (NAE) is a recently recognized dermatosis almost exclusively associated with hepatitis C virus (HCV) infection and closely related to a group of necrolytic erythemas and metabolic syndromes. NAE is characterized by pruritic, symmetric, well-demarcated, hyperkeratotic, erythematous-to-violaceous, lichenified plaques with a rim of dusky erythema on the dorsal aspects of the feet and extending to the toes. Based on morphology and histopathologic features, NAE can be difficult to distinguish from certain groups of necrolytic erythemas, which include necrolytic migratory erythema, acrodermatitis enteropathica, biotin deficiency, niacin deficiency, and essential fatty acid deficiencies.

Necrolytic acral erythema (NAE) is a member of the necrolytic erythemas, which include necrolytic migratory erythema (NME), acrodermatitis enteropathica, and various dermopathies secondary to nutritional deficiencies. NAE is distinct from the other necrolytic erythemas by virtue of its consistent association with hepatitis C (HCV) together with the acral distribution of its lesions, in particular, dorsal hands and feet. Although its etiology is unknown, NAE has been reported to respond to zinc replacement, suggesting a causal relationship. Read More
