Mannose-binding lectin gene polymorphism in psoriasis and vitiligo: an observational study and computational analysis.

Introduction: Psoriasis and vitiligo are inflammatory autoimmune skin disorders with remarkable genetic involvement. Mannose-binding lectin (MBL) represents a significant immune molecule with one of its gene variants strongly linked to autoimmune diseases. Therefore, in this study, we investigated the role of the MBL variant, rs1800450, in psoriasis and vitiligo disease susceptibility.

Expression Signature of Immune-Related MicroRNAs in Autoimmune Skin Disease: Psoriasis and Vitiligo Insights.

Background: Psoriasis and vitiligo are both chronic, skin-specific diseases classified as autoimmune diseases due to the involvement of several biochemical pathways in their pathogenesis, similar to those altered in other autoimmune diseases. The role of miRNAs in regulating skin autoimmune function has yet to be fully characterized.

Aim: The aim of this study was to assess the expression profile of a panel of 11 circulating immune-related miRNAs in patients with autoimmune skin diseases, specifically psoriasis and vitiligo, and correlate their expression signature with the clinicopathological features of the diseases.

Circulating microRNA203 and its target genes' role in psoriasis pathogenesis.

Numerous microRNAs (miRNAs) have been found to have an aberrant expression in the peripheral blood or psoriasis patients' lesions. Psoriasis was shown to have the abnormal expression of microRNA-203 (miR-203). It is a skin-specific signal that governs cellular proliferation in a protein kinase C-dependent manner and is mostly generated by keratinocytes.

Intralesional injection of purified protein derivative versus Candida antigen in treatment of genital warts.

The Genital warts are common sexually transmitted diseases caused by definite types of human papillomavirus. There are many strategies for the treatment of genital wart and intralesional immunotherapy is considered to be a safe and effective treatment modality. However, there are lack of studies that comparing the clinical effectiveness of intralesional purified protein derivative (PPD) and Candida antigen (CA) in genital wart treatment.

Investigating melanogenesis-related microRNAs as disease biomarkers in vitiligo.

Vitiligo is considered a disabling disease that affects physical, social, psychological, and occupational aspects of an individual's quality of life. The search for non-invasive and reliable biomarkers for vitiligo's early diagnosis, prognosis, and treatment prediction is under intensive investigation. There is currently an emerging interest in employing miRNAs as biomarkers to predict vitiligo diagnosis and prognosis, inspired by the well-preserved nature of miRNAs in serum or plasma.

The lncRNA PRINS-miRNA-mRNA Axis Gene Expression Profile as a Circulating Biomarker Panel in Psoriasis.

Background: The interaction between genes and the environment in psoriasis is firmly coupled by epigenetic modification. Epigenetic modifications are inherited variations in gene expression devoid of DNA sequence alterations. Non-coding RNAs are regarded as one of the epigenetic modifications that lead eventually to enduring heritable variations in gene expression.

PSORS1 Locus Genotyping Profile in Psoriasis: A Pilot Case-Control Study.

(1) Background: The psoriasis susceptibility 1 (PSORS1) locus, located within the major histocompatibility complex, is one of the main genetic determinants for psoriasis, the genotyping profile for three single-nucleotide polymorphisms (SNPs) comprising the PSORS1 locus: rs1062470 within genes, rs887466 within gene, rs10484554 within gene, were investigated and correlated with psoriasis risk and severity. (2) Methods: This pilot case-controlled study involved 100 psoriatic patients and 100 healthy individuals. We investigated three SNPs and assessed the relative gene expression profile for the gene.

Assessment of changes in color and size of vitiligo lesions during treatment with narrow band ultraviolet B.

Background: Many treatment modalities have been used to stabilize vitiligo and induce repigmentation. Several methods were used to monitor the color changes inside the treated lesions such as spectroscopes and colorimeters that measure the melanin index inside the lesion.

Objective: To study whether the colorimeter and point counting technique can be used as objective methods in monitoring vitiligo lesions during treatment with Nb-UVB.

Split-face comparative study of fractional Er:YAG laser versus microneedling radiofrequency in treatment of atrophic acne scars, using optical coherence tomography for assessment.

Background: Efficacy and safety of ablative fractional laser used for treatment of acne scars have been described in several studies. Recently, microneedling radiofrequency treatment has been showing promising results with low risk of side effects and rapid healing time.

Objective: To study efficacy and safety of ablative fractional Er:YAG laser 2940 nm and microneedling radiofrequency for facial atrophic acne scar.
