Alitretinoin is a new oral retinoid authorized for use in grownups that have severe chronic hand eczema (CHE). A comprehensive search to solicit all studies of alitretinoin for the treatment of CHE. A comprehensive search to solicit all studies of alitretinoin for the treatment of CHE including randomized controlled trials (RCTs) or uncontrolled trials, re-treatment studies, open-label studies, or observational studies, along with case series of 10 or more participants. Physician global assessment (PGA), patient global assessment (PaGA) and modified total lesion symptom score (mTLSS) are the methods and outcomes criteria. Generated effect size and 95% confidence intervals were calculated for the outcomes. Heterogeneity and publication bias were also tested for all selected trials. When a noteworthy Q statistic (P< 0.1) demonstrates the heterogeneity crosswise over studies, an arbitrary impact model is used. On the other hand, a settled effect model is when heterogeneity is not shown. The initial search yielded 408 records of which 15 articles were selected. The 15 clinical trials included 3734 patients with CHE. Among alitretinoin-treated patients, the PGA effect size was directly proportional to the drug dosage, ranging from 40% to 69%, while the PaGA score ranged from 28.8% to 62.4%, and mTLSS ranged from 60.4% to 76.9%, much higher than placebo. A higher drug dose was about twice as effective as lower dose. The odds ratio for a better outcome with drug treatment taking duration into account was about 3-4 times that versus placebo. In conclusions, alitretinoin cleared lesions in about 50% of cases, particularly using a higher dose for a longer duration.

In severe cases of atopic dermatitis (AD) systemic treatment is indicated. So far, cyclosporine and systemic glucocorticosteroids represented the only systemic treatment options approved for the indications of AD in Germany; however, from clinical practice there is increasing evidence for beneficial therapeutic effects in AD by other immunosuppressive or immunomodulatory substances, such as mycophenolate, methotrexate, alitretinoin and ustekinumab. Beyond this, ongoing research activities focus on a better understanding of genetic and immunological aspects of this chronic inflammatory skin disease. Regarding treatment with mycophenolate, genetic polymorphisms in AD patients could be identified that might predict responsiveness to this medication. Moreover, several new substances specifically targeting inflammation in AD are currently being studied and the first promising treatment effects on skin condition and pruritic symptoms of AD could be observed. As an exceptional result of this development in September 2017 in Europe and therefore in Germany the first biologic as first-line treatment was approved for the indication of moderate to severe AD in adults. Dupilumab is a human monoclonal IgG4 antibody that blocks a subunit of the interleukin (IL)-4 and IL-13 receptors, thus inhibiting the proinflammatory effects of these cytokines. Furthermore, the cytokine IL-13 itself, the IL-31 receptor, which is of particular relevance for pruritus in AD, the histamine-4-receptor and Janus kinases represent further promising targets currently being investigated in clinical trials for the treatment of AD.

Kaposi's Sarcoma (KS) is a multicentric angioproliferative cancer of endothelial cells (ECs) caused by Human Herpesvirus 8 (HHV8) characterized by clinical heterogeneity depending on the host immune conditions. Despite its incidence has dramatically decreased in developed countries after the introduction of Highly Active Antiretroviral Therapy (HAART), KS remains the most frequent tumor in HIV-infected patients worldwide. Clinical presentation varies from an indolent slowly progressive behavior, generally limited to the skin, to an aggressive and rapidly progressing disease. In more than 50% of cases, the skin lesions are often associated with a more or less important visceral involvement, particularly to the oral cavity and the gastrointestinal tract that are involved in 35% and 40% of cases respectively. A large number of treatments can be used both as local and as systemic therapy. Particularly, HAART represents the first treatment in patients with moderate lesions limited to skin, and it can be sufficient to reduce significantly the size of lesions and, often, the complete disappear in 35% of cases after 3-9 months of treatment. In case of a rapidly progressive disease with extensive cutaneous and/or visceral involvement systemic drugs are used such as the liposomal anthracyclines pegylated liposomal doxorubicin (PLD) and daunorubicin citrate liposome (DNX), the combined treatment adriamycin-bleomycin-vincristine (ABV) and bleomycin-vincristine (BV), Paclitaxel and Interferon-alfa. In patients with limited skin localization, the local treatment can play an important role. Local medical therapy is based on the use of alitretinoin, antineoplastic drugs vincristine, vinblastine and bleomycin and Sodium Tetradecyl Sulfate (STS). In addition to medical therapy, physical treatment, such as cryotherapy and radiotherapy, are also commonly used.

Lichen amyloidosis (LA) is characterized by the deposition of amyloid that may respond to chronic scratching that may be secondary to atopic dermatitis, stasis dermatitis, or interface dermatitis. Despite the development of several therapeutic strategies, including topical steroids, oral antihistamines, cyclosporine, and retinoids, an effective treatment for LA has not been established. A 49-year-old woman who has been treated irregularly for atopic dermatitis for 7 years presented with localized brownish papules on the left forearm and right elbow. They developed 3 months prior and were becoming more prominent despite of treatment with cyclosporine, oral antihistamines, and topical steroids for 5 months prior to presentation. A skin biopsy revealed amyloid deposition in the dermal papillae and the patient was diagnosed with LA associated with atopic dermatitis. A 6-month course of daily oral alitretinoin 30 mg produced marked improvement in the thickness and color of the hyperkeratotic papules without aggravation of the patient's atopic dermatitis. Histologic evaluation showed clearance of amyloid deposition and almost normalization of the epidermal changes. Herein, we report a case of LA treated with alitretinoin and suggest that it could be a potential treatment option for LA, especially in patients with inflammatory skin diseases including atopic dermatitis.

The main intention of this study was the investigation of impact of natural biologically active ligands of nuclear retinoid/retinoid X receptors (all-trans and 9-cis retinoic acid) on proteomic pattern in human estrogen receptor negative breast cancer cell line MDA-MB-231. For this purpose, proteomic strategies based on bottom-up method were applied. The total cell proteins were extracted utilizing a commercially Radio-Immunoprecipitation Assay (RIPA) buffer and separated on 2D sodium dodecyl sulfate polyacrylamide gel electrophoresis (2D SDS-PAGE). The proteins were subsequently digested in-gel by trypsin and their characterization was achieved by MALDI-TOF/TOF. By employing PDQuest™ software, we identified more than 50 proteins affected by retinoic acid isomers. For more information, 9 proteins which are associated with tumor process were selected. We determined that derivatives of retinoic acid led to significantly reduced level of proteins belonging to metabolic pathway (e.g. glyceraldehyde-3-phosphate dehydrogenase or pyruvate kinase 2) or to other cellular processes as apoptosis, regulation of transcription process or epithelial-mesenchymal transition (e.g. annexins, nucleoside diphosphate kinase B, vimentin). On the other hand all-trans retinoic acid treatment indicates up-regulated effect for heterogeneous nuclear ribonucleoprotein A2/B1.
