Estimates of the prevalence of psoriasis have varied across studies. A systematic review of international population-based studies found wide variation in the global prevalence of psoriasis 1. Prevalence estimates also varied in relation to demographic characteristics in that studies confined to adults reported higher estimates of psoriasis compared with those involving all age groups. Studies on the prevalence and incidence of psoriasis have contributed to a better understanding of the burden of the disease. However, further research is required to fill existing gaps in understanding the epidemiology of psoriasis and trends in incidence over time. Epidemiology. Estimates of the prevalence of psoriasis in adults vary globally, with higher rates reported at higher latitudes and Western countries. While research over the last few decades has begun to elucidate psoriasis susceptibility genes, these studies have been composed primarily of individuals of European or Asian descent.
Prevalence estimates also varied in relation to demographic characteristics in that studies confined to adults reported higher estimates of psoriasis compared with those involving all age groups. Studies on the prevalence and incidence of psoriasis have contributed to a better understanding of the burden of the disease. The prevalence of psoriasis is estimated to be about 1.3-2.2 in the UK, with the highest prevalence being in white people. A number of studies have suggested that people with psoriasis may have an increased risk of cardiovascular disease, lymphoma and non-melanoma skin cancer. Fissuring within plaques can occur when lesions are present over joint lines or on the palms and soles. Gentle scraping accentuates the scale (vigorous scraping causes pinpoint bleeding – Auspitz’ sign). The sequence of choice of topical agents will vary according to the extent and pattern of psoriasis and the patient preference. Studies on the prevalence and incidence of psoriasis have contributed to a better understanding of the burden of the disease. However, further research is required to fill existing gaps in understanding the epidemiology of psoriasis and trends in incidence over time.
Over the past four decades, a number of studies have been published confirming the varied clinical patterns seen in PsA. Large literature has been published focusing on its varied aspects. In the USA, the prevalence of psoriasis was estimated to be around 4.6 while in Canada it was 4.7. There are only few studies from India which have analyzed the clinical spectrum of the disease in psoriasis patients Table 1. Kaur et al. studied nail changes in 167 psoriasis patients over a period of five years. Large literature has been published focusing on its varied aspects. There is a no dearth of information available; however, many questions remain that are still unanswered. There is a growing number of population-based studies providing worldwide prevalence estimates of psoriasis. Prevalence of psoriasis varies in different parts of the world.
Global Epidemiology Of Psoriasis: A Systematic Review Of Incidence And Prevalence
For the treatment of moderate to severe psoriasis. Its long term safety profile continues to be studied, but results so far are positive. Over half of patients with psoriasis have abnormal changes in their nails, which may appear before other skin symptoms. In some cases, nail psoriasis is the only symptom. Estimates on its prevalence among people with psoriasis range from 2 – 42. Individual needs vary widely, and treatment selection must be carefully discussed with the doctor. In several studies from different countries, the prevalence of psoriasis was estimated at 1.5-2.8 of women and 2.3-s2.9 of men 1, 2. Different types of outpatient visits and hospitalisation days have varying costs. The impact of psoriasis on quality of life has been studied in select patient populations. Population-based estimates of the prevalence of psoriasis,. Dermatitis herpetiformis (DH), or Duhring’s disease, is a chronic blistering skin condition, characterised by blisters filled with a watery fluid. Estimates of DH prevalence vary from 1 in 400 to 1 in 10000. Untreated, the severity of DH can vary significantly over time, in response to the amount of gluten ingested. Various research studies have pointed out different potential factors that may play a larger or smaller role in the development of dermatitis herpetiformis. Caregivers were significantly more likely to have some college education than to have a high school education or less or to be a college graduate; they were also significantly more likely to be married or part of an unmarried couple than to be divorced, separated, widowed, or never married (Table 1). Estimates of the prevalence of caregivers vary across studies because of differences in definitions, sampling, and the age of person receiving care (3). The standardized mortality ratios varied from 1.28 to 2.98, with primary differences being due to method of diagnosis, geographic location, demographics, study design (inception versus community cohorts), thoroughness of follow up, and disease status 23 26. Population-based studies specifically examining trends in mortality over time have concluded that the excess mortality associated with RA has remained unchanged over the past two to three decades 19. The few population-based estimates available indicate that the prevalence of juvenile rheumatoid arthritis (JRA) is approximately 1 to 2 per 1,000 children, and the incidence is 11 to 14 new cases per 100,000 children.
