Heterogeneity among Different Presentations of Psoriasis. A Review of the Broad Spectrum of Its Presentation

Abstract

Various clinical manifestations can be seen in patients who suffer from psoriasis, which is a chronic inflammatory skin condition that is influenced by hereditary factors and the immune system's response. Although the global incidence of the disease is approximately 2%, the prevalence of the disease varies across geographical regions and ethnic groups. Psoriasis vulgaris, the most common cause of psoriasis, is characterized by red, itchy patches that are covered in silver-colored scales. This form of psoriasis primarily affects the scalp, limbs, and trunk. Inverse psoriasis, guttate psoriasis, pustular psoriasis, and erythrodermic psoriasis are some of the other clinical subtypes of psoriasis. Each of these subtypes has its own unique characteristics and adverse effects. In addition to its manifestations on the skin, psoriasis is linked to a number of other medical conditions that simultaneously manifest themselves. These conditions include hyperlipidemia, hypertension, coronary artery disease, type 2 diabetes, and obesity. Those who suffer from psoriasis are at a greater risk of developing cardiovascular disease, and the severity of the condition is correlated with the number of instances of diabetes and cardiovascular events. In addition, approximately forty percent of patients are affected by psoriatic arthritis, which frequently occurs in conjunction with nail involvement. Psoriasis patients have been the subject of recent research that has shed light on systemic inflammation and cardiovascular risk. These studies have utilized imaging techniques such as 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT) and nuclear magnetic resonance spectroscopy. Treatments that target IL-23 and IL-17 have demonstrated encouraging results; however, there are still concerns regarding the long-term efficacy and drug survival of these treatments. Psoriasis has a significant impact on the quality of life of patients, causing them to experience psychological distress that is comparable to that of cancer and depression. The treatment, on the other hand, has the potential to significantly alleviate symptoms and improve overall good health. The current research endeavors to broaden the range of treatment options, with a particular emphasis on identifying novel molecular pathways. In conclusion, although there has been significant progress made in understanding and treating psoriasis, there are still challenges surrounding the optimization of therapy selection and the management of the condition over the long term. It is necessary to conduct additional research in order to better understand the intricate genetic and immunological factors that contribute to the disease and to improve the outcomes of treatment for those who are afflicted with it.
