RESUMEN

Oral psoriasis therapies include both older traditional immunosuppressants, such as methotrexate, cyclosporine, and acitretin, as well as newer, more targeted agents, such as apremilast, deucravacitinib, and oral interleukin-23 receptor antagonists. Patients may prefer oral therapies to injectable therapies based on the route of administration. Both older and newer oral psoriasis therapies can be utilized effectively in the treatment of psoriasis. Here, we will review oral agents used in the treatment of psoriasis as well as provide commentary on their role in our current, evolving psoriasis treatment paradigm.

RESUMEN

Psoriasis is a chronic, immune-mediated, hyperproliferative skin disease. Etiopathogenesis of psoriasis is not well understood. Plexin B2 was found to have effects on CD100-mediated T-cell morphology and expressed in the immune system. It may play a role in the pathogenesis of psoriasis. To assess the tissue level of plexin-B2 and plexin B2 related gene polymorphism which is signal regulatory protein gamma (SIRPγ-rs71212732) in psoriatic patients before and after NB-UVB, acitretin therapy alone or in combination and to detect correlation between level of tissue plexin B2 and disease severity and improvement. This single blinded randomized controlled trial was carried on 50 psoriatic patients and 50 healthy controls. Psoriasis Area and Severity Index score (PASI) was used to evaluate the disease severity. Tissue plexin-b2 level was measured using ELISA and SIRPγ-rs71212732 (T\C) was assessed using TaqMan™ assays and real-time PCR. A significant lower tissue plexin-B2 level was observed in control group (2.9 ± 0.6 pg/g) than cases (25.8 ± 2.8, pg/g) (p < 0.001). Also, a significantly higher tissue plexin-B2 level was observed in sever psoriasis (32.7 ± 3.8 pg/ml) in than moderate psoriasis (13.6 ± 2.1 pg/ml, p = 0.001). Tissue plexin B2 was positively correlated with diseases severity. Significantly higher (TC& TT) genotypes and mutant (C) allele among patients compared to the controls, p < 0.001 for all. Tissue plexin-b2 level was high in psoriasis vulgaris with positive correlation with disease severity and decreased after treatment. This may indicate a role of plexin-b2 in psoriasis vulgaris pathogenesis.

RESUMEN

BACKGROUND: Lipoid proteinosis (LP), also known as Urbach-Wiethe disease, is a rare autosomal recessive genodermatosis, caused by mutations in the ECM1 gene. This results in the deposition of periodic acid-Schiff (PAS)-positive, hyaline-like material on the skin, mucosae and internal organs. OBJECTIVES: To present a case report of LP and a systematic review to synthesize the scientific literature on the management of this uncommon and frequently missed diagnosis. METHODS: We present a case report of a 48-year-old man with LP who exhibited significant improvement after oral acitretin therapy. To address the lack of large case-control studies on LP treatment, we performed a systematic review of the literature following the PRISMA 2020 criteria. The search was conducted in PubMed, Web of Science, Cochrane and Scopus databases from inception until June 2023. To assess the methodological quality of case reports and case series, we used the Joanna Briggs Collaboration critical appraisal tool. RESULTS: We included 25 studies that met eligibility criteria. Data from 44 patients with a histopathologically confirmed diagnosis were analysed. Treatment ranged from systemic therapies (acitretin, etretinate, dimethyl sulfoxide, corticosteroids, penicillamine) to surgical or laser procedures. Regarding methodological quality, the main discrepancies arose in the reporting of participant characteristics and treatment interventions. CONCLUSIONS: Low-dose oral acitretin could have potential in managing LP, exhibiting fewer side-effects compared with other therapeutic agents. Further research is needed to establish more comprehensive and evidence-based treatment guidelines.

RESUMEN

BACKGROUND: Palmoplantar psoriasis (PPP) is a localized variant of psoriasis that may be resistant to topical therapy, owing to the poor penetrability of topical agents at this anatomical site. Modalities that enhance localized cutaneous delivery of drugs could help to solve this problem. Iontophoresis is one such procedure that augments transdermal drug delivery, thus enabling better and expeditious therapeutic outcomes. OBJECTIVE: To compare the therapeutic efficacy and safety of iontophoresis with tretinoin 0.05% cream and tacrolimus 0.1% ointment in treating patients with PPP. METHODS: Sixty patients with PPP (28 males and 32 females, age range 8-76 years) were enrolled and randomly assigned to one of two groups comprising 30 patients each. One group (12 males and 18 females) received iontophoresis with tretinoin 0.05% cream; the other (16 males and 14 females) received iontophoresis treatment with tacrolimus 0.1% ointment. Both groups received treatment weekly from baseline until 4 weeks and then fortnightly at weeks 6 and 8. Clinical images were taken at each visit and improvement of psoriasis was evaluated using the erythema, scaling, induration and fissuring (ESIF) score. The percentage reduction in ESIF score was also assessed on completion of treatment and the grade of improvement noted for each patient. RESULTS: Twenty-seven patients in the iontophoresis with tretinoin 0.05% cream group and 29 in the iontophoresis treatment with tacrolimus 0.1% ointment group completed the study. The mean (SD) ESIF score in the former decreased significantly from 8.7 (2) at baseline to 3.2 (1.7) at the study endpoint (P < 0.001). Similarly, in the latter group, there was a substantial reduction in mean (SD) ESIF score from 8.2 (1.9) at baseline to 3.3 (1.1) at the study end (P < 0.001). No significant adverse effects were encountered in either treatment arm. CONCLUSIONS: Iontophoresis using tretinoin and tacrolimus was found to be effective and safe for the treatment of PPP. Although iontophoresis with tretinoin showed slightly better results than with tacrolimus, these were not statistically significant.

RESUMEN

OBJECTIVE: To evaluate the clinical efficacy of peeling with a microemulsion formulation containing 1% retinoic acid. MATERIALS AND METHODS: After development of the product, 60 patients with melasma were randomly divided into three groups (n = 20): Group 1-application of conventional 1% retinoic acid peeling (RA 1%). Group 2-application of 1% retinoic acid peeling in microemulsion (RA 1%M). Group 3-Application of placebo. The groups were submitted to four peeling sessions, fortnightly on Days 0, 15, 30, and 45, and analyzed at the time intervals of 0, 15, 30, 45, and 60 days. Evaluation was made by using the Melasma Area and Severity Index (MASI) and Melasma Quality of Life (MelasquoL) instrument. Hemato-biochemical parameters were also evaluated at Days 0 and 60. After obtaining the results, normality was evaluated by means of the Kolmogorov-Smirnov test and afterwards, the following tests were applied: Friedman statistical (to test the effect of the treatments on the MASI index); Wilcoxon, (for comparison between pairs to test the effect of treatments on the MelasQoL index); Kruskal-Wallis, (to test the differences between the groups); and Mann-Whitney, (comparisons between treatments). The level of significance adopted was 5% (α = 0.05). RESULTS: The three groups presented a significant reduction in the MASI index, indicating the effect of all the treatments on reducing the melasma (p < 0.001). A significant reduction in the stains was observed with the use of retinoic acid peeling delivered in microemulsion (62%) when compared with the conventional peeling with 1% retinoic acid in a conventional vehicle (26%) and the placebo (12%). There was also a significant reduction in the MelasQoL index (sum of all the aspects) in the three groups, indicating the effect of all the treatments, including the placebo, on the overall quality of life of those with melasma. However, RA 1%M the treatment that promoted the greatest effect on the quality of life of individuals. In percentage terms, the RA 1%M provided a mean reduction of 30% in the MelasQoL index, against 13% of the conventional treatment and only 4% of the placebo. When the hemato-biochemical parameters were compared on Days 0 and 60, there were no significant changes in the results. CONCLUSION: The chemical peeling performed with RA 1%M was effective for the treatment of melasma, and was shown to be superior to the peeling performed with retinoic acid in a conventional vehicle, in reducing the stains and improving the quality of life of patients.

RESUMEN

Acne vulgaris stands out as the most prevalent skin disorder among teenagers and young adults, causing physical discomfort and considerable economic and psychological burdens on individuals and society. A wide range of topical and systemic therapies are available in acne treatment. Chemical peeling is a skin resurfacing technique designed to rebuild healthy skin using exfoliating substances, a simple and affordable process with various dermatological uses. Chemical peels, classified as superficial, medium, and deep, have been utilized for acne vulgaris and multiple other skin issues. In these chemical peels, a diverse range of chemical substances is employed, each with its unique mode of action. Among these, α-hydroxy and ß-hydroxy acids have gathered attention for their efficacy in reducing acne lesions and enhancing overall skin appearance. Acids, such as salicylic acid, glycolic acid, or lactic acid, are commonly used in chemical peels due to their exfoliating and sebum-regulating properties. Despite the widespread use of these acids, there exists a lack of consensus regarding the most effective acid type and concentration for treating acne-prone skin. This review aims to bridge this knowledge gap by evaluating the effectiveness and safety of various organic acids used in chemical peels specifically for acne-prone skin. The findings of this comprehensive bibliographic review indicate that organic acid-based chemical peels represent effective and safe treatment options for individuals with acne-prone skin. Their adaptability sets these treatments apart; the choice of organic acid can be tailored to meet individual patient needs and tolerability levels. This personalized approach ensures that patients receive optimal care while minimizing the risks associated with the treatment. As research in this field progresses, it is anticipated that a more nuanced understanding of the ideal acid type and concentration will emerge, further enhancing the efficacy and safety of chemical peels for acne-prone skin.

RESUMEN

BACKGROUND: Excessive sebum production is a factor in acne development. Tazarotene 0.045% lotion has demonstrated reductions in acne lesions and acne-induced sequelae. OBJECTIVE: Evaluate efficacy, changes in skin oiliness, and safety with tazarotene 0.045% lotion in participants with moderate-to-severe acne and oily skin. METHODS: In two phase 3, double-blind, 12-week studies (NCT03168321; NCT03168334), participants aged ≥ 9 years with moderate-to-severe acne were randomized 1:1 to once-daily tazarotene 0.045% lotion or vehicle lotion (N = 1614). This pooled, post hoc analysis included only participants self-categorized with oily skin at baseline on the Acne-Specific Quality of Life questionnaire item 19 (scores: 0 [extremely oily] to 6 [not at all oily]). Inflammatory/noninflammatory lesion counts, treatment success, skin oiliness, treatment-emergent adverse events (TEAEs), and cutaneous safety/tolerability were evaluated. RESULTS: In all participants with oily skin (n = 793), tazarotene provided greater reductions in inflammatory/noninflammatory lesions (p < 0.001, both) and greater treatment success rates versus vehicle (p < 0.01) at week 12. Over two-thirds of polymeric lotion-treated participants had subjective skin oiliness reductions by week 12, with around a third reporting 'low/not' oily skin. Tazarotene TEAE rates were similar to the overall population. CONCLUSIONS: Once-daily treatment with tazarotene 0.045% polymeric emulsion lotion may help improve patient-perceived skin oiliness in those with moderate-to-severe acne.

RESUMEN

The term 'inherited ichthyosis' refers to a heterogeneous group of mendelian disorders of cornification that involve the integument with varying degrees of scaling. The management of ichthyosis poses a challenge for most physicians. Treatment options proposed in the literature include moisturizers, topical keratolytics, topical and systemic vitamin D analogues, and topical and systemic retinoids; however, some of these modalities are less reliable than others. Despite the therapeutic impasse imposed by the options above, the emergence of pathogenesis-based treatments along with novel gene therapies appear promising and hold the potential to halt or even revert disorders that arise from single genetic mutations, although research is still quite lacking in this domain. Hence, this review aims to highlight the various treatment modalities available for the management of the cutaneous manifestations of non-syndromic inherited ichthyosis, with an added emphasis on pathogenesis-targeted therapies.

RESUMEN

Scalp involvement is seen in a majority of individuals with psoriasis, a chronic autoimmune skin disease with variable phenotypes. Occasionally, isolated scalp involvement is observed; and this causes significant psychosocial morbidity. Management of scalp psoriasis is difficult, in part due to the difficulty of applying topical agents and its refractory nature. Various treatment options are available with variable efficacy. Topical agents include topical steroids, keratolytics, tar and anthralin compounds, vitamin D analogues, and vitamin A derivatives. The combination treatment of topical betamethasone and calcipotriene is the most effective topical therapy. Systemic agents include conventional agents such as methotrexate, cyclosporine, and oral retinoids. Biologics offer a greater efficacy, with near complete or complete clearance of the scalp. In this article we review the published literature on adult and scalp psoriasis to highlight its treatment. Articles published in peer-reviewed journals were included for qualitative analysis of the literature, including reviews, clinical trials, case series, case reports published in the electronic database (MEDLINE/PubMed) through June 2021, cross references of respective articles, and trials from clinicaltrials.gov. J Drugs Dermatol. 2022;21(8):833-837. doi:10.36849/JDD.6498.

RESUMEN

Cutaneous amyloidosis can be a part of a systemic disease or can result from a localized process limited to the skin. It usually presents as pruritic hyperpigmented macules, papules or nodules, which are notoriously resistant to treatment. We performed a hospital-based pilot case series to assess the efficacy and safety of sequential salicylic acid (SA) and glycolic acid (GA) chemical peels. Patients underwent sequential chemical peel therapy with SA 20% and GA 35% used alternately each week for a total of 6 weeks. At subsequent follow-up visits, good clinical outcome and long-term maintenance was observed. This study highlights the promising role of chemical peels in this difficult and distressing disorder.

RESUMEN

Plantar warts are among the most common skin conditions and are classically resistant to treatment. To perform an evidence-based evaluation of the efficacy and safety of available treatment options for plantar warts, we conducted a systematic review of PubMed and Cochrane databases to identify large interventional and observational studies involving more than 100 patients who were treated for plantar warts from inception to October 2020. We identified only nine contributions meeting our inclusion criteria (N ≥ 100), representing 1,657 adult and pediatric patients with plantar warts. Treatments included in this review were topical keratolytic agents, cryotherapy, laser therapies, and intralesional and systemic treatments. Our evidence-based review of the larger studies suggests keratolytic agents and destructive treatments, in particular salicylic acid and cryotherapy, remain the primary treatments for plantar warts. Treatment with pulsed dye laser had the lowest rate of recurrence. Newer treatments and intralesional treatments were not represented owing to lack of large studies involving these modalities.

RESUMEN

BACKGROUND: Acne vulgaris is a common skin condition affecting the pilosebaceous unit of the skin characterized by the presence of comedones, papules, pustules, nodules, and cysts, which might result in permanent scars. It commonly affects adolescents, but it can occur in any age-group with the second group of incidence in young women in their 30s. Acne vulgaris can highly affect a person's quality of life. Therefore, it is necessary to act against it to prevent emotional impact and long-term complications. AIM: This study aimed to demonstrate the efficacy of a chemical peel in combination with a home care-exfoliating and purifying product in improving mild and moderate acne. METHODS: The study included 45 patients with mild-to-moderate acne. Patients were treated with a chemical peel containing a mix of salicylic acid, pyruvic acid, and retinoic acid once every 3 weeks for 4 times, plus a home care treatment after the healing process. Michaelson's acne severity score, Subject Global Aesthetic Improvement Scale, and Face Skin Q questionnaire were used to evaluate patients' skin improvement and patients' satisfaction. RESULTS: All patients have shown improvement in skin lesions after 4 sessions of chemical peel according to Michaelson's acne severity score and Subject Global Aesthetic Improvement Score. Face Skin Q questionnaire demonstrated an improved quality of life in all treated patients. CONCLUSION: The combination of salicylic acid-based chemical peel plus exfoliating home care treatment appears to be a very good strategy against acne. Therefore, the physician may use this combination as an effective treatment for patients dealing with acne vulgaris.
