A study of clinicohistopathological correlation in patients of psoriasis and psoriasiform dermatitis
Indian Journal of Dermatology, Venereology and Leprology, 2009
Background: Psoriasis has different clinical variants, which mimic diverse dermatological conditions and may require a histopathological conÞ rmation of the diagnosis. Studies to establish a clinicohistopathological concordance (and its determinants), in psoriasis and psoriasiform dermatitis are lacking. Aims: The present study was designed (a) to correlate the clinicohistopathological features of psoriasis and psoriasiform dermatitis, and (b) to identify determinant(s) that may contribute to the diagnosis of psoriasis and psoriasiform dermatitis. Methods: This was a prospective study involving 100 patients, with a single clinical diagnosis of psoriasis or with psoriasis as one of the differential diagnoses, and its correlation with histopathological features. Results: The clinical features of typical scale (P = 0.0001) and Auspitz's sign (P = 0.0001), and histological evidence of suprapapillary thinning (P = 0.0001) and absent granular cell layer (P = 0.0001) were found to be statistically signiÞ cant contributors to the clinicohistological concordance in cases of psoriasis. Vertical orientation of collagen bundles (P = 0.0001) and lymphocytic exocytosis (P = 0.003) were found to be signiÞ cantly associated with diagnosis of psoriasiform dermatitis. Conclusion: The present study reconÞ rms the diagnostic accuracy of silvery white scale, Auspitz's sign, and Koebner's phenomenon in a clinical setting suggestive of psoriasis. However, in their absence, histological evidence of suprapapillary thinning and absent granular layer, in addition to the Munro microabscess and Kogoj's abscess, may contribute to the diagnosis of psoriasis. Similarly, vertical orientation of collagen bundles and lymphocytic exocytosis may point toward a diagnosis of psoriasiform dermatitis.

Background-Psoriasis is a group of common chronic inflammatory and proliferative skin conditions associated with systemic manifestations in many organ systems. Its prevalence is poorly defined in India and its presentation varies with different stages and can simulate various other conditions also. Materials and Methods-This retrospective study was conducted to study the clinical and histomorphological variants of psoriasis and incidence of age and sex distribution in various types of psoriasis in a tertiary care hospital. 9 parameters were used to assess and categorize the various types of psoriasis-1) Hyperkeratosis 2) Parakeratosis 3) Munro's microabscesses 4) Pustule of Kogoj 5) Supra-papillary thinning 6) Elongated rete ridges 7) Inflammatory infiltrate in the dermis 8) Capillary proliferation and dilatation 9) Spongiosis Results-A male preponderance with maximum cases in the 31-40 years age group was found in our study. The predominant histological type was that of Psoriasis vulgaris (63%) followed by Chronic Plaque Psoriasis (18%). Amongst the cutaneous features of psoriasis, Scales were the most common (92%) followed by plaques (83%). The most commonly involved site was that of the upper extremities (79%). Amongst the epidermal histopathological features of psoriasis, acanthosis was seen in 100% cases followed by hyperkeratosis in 95% cases. The dermal features showed dermal infiltration in 97% cases. Conclusion-Psoriasis has multiple relapses and remissions and also varied clinical presentations. Its diagnosis at the earliest is important to halt its progression and histomorphology helps in that. This study concluded that even though most changes occur in the epidermis in cases of psoriasis, there are a few dermal changes too which can aid the pathologist in arriving at the diagnosis. This study also helped in finding the prevalence of this disease in India, as there is paucity of the same in our country. Thus overall, this study helped in finding the various histomorphological features which are diagnostic of psoriasis as well as their incidence in various subtypes of psoriasis. It also adds to the data of the disease in our country and will help in better clinical management as well as triage of patients.

The main objectives of this review article are to discuss different aspects of psoriasis including its etiology, pathogenesis, co-morbidities, complications and management etc. and to discuss about psychosocial impact & quality of life in the patients of psoriasis. Psoriasis is one of the most common dermatologic diseases affecting upto 2.5 % of world population. The disease psoriasis, most commonly manifests on the skin of the elbows, knees, scalp, lumbosacral areas, intergluteal clefts and glans penis. In 30% of patients, the joints are also affected. The skin is the important organ of communication with the external world and have an eternal relationship with mind (psyche). Therefore, more than a cosmetic nuisance, psoriasis produces anxiety, depression and other psychological problems that affect the quality of life. Psychological factors have traditionally been associated with the onset, development and persistence of psoriasis. Stress is emphasized as one of the major important factors in the initiation or exacerbation of psoriasis. Patients of psoriasis always experience physical, mental and socio-economic embarrassment in the society. This embarrassment leads to mental stress which further causes aggravation of pre-existing disease. Psoriasis is now considered a complex, chronic, multifactorial, inflammatory disease with involvement of immunological, genetic and environmental factors.

Nowadays it is accepted that psoriasis is a chronic, recurrent, immune-mediated inflammatory disease, with a recognised genetic predisposition. The primary immune defect appears to be an increase in cell signalling via chemokines and cytokines that act upregulating gene expression, causing keratinocyte hyperproliferation. T lymphocytes and their cytokines and chemokines appear to be the driver of lesion development and persistence, although other cells, such as endothelial cells, dendritic cells, neutrophils and www.intechopen.com Psoriasis-A Systemic Disease 70 keratinocytes play also an important role, along with other cytokines and growth factors (Chen, de Groot et al.; Wollenberg, Wagner et al. 2002; Sano, Chan et al. 2005). Currently, it is proposed that psoriasis development depends on skin infiltration of T helper (Th)1/Th17 cells that stimulate macrophages and dermal dendritic cells to release mediators that sustain inflammation and cause abnormal keratinocyte proliferation. Interleukin (IL)-23 has the potential to activate Th17 cells, stimulating their survival and proliferation and serving as a key master cytokine regulator in psoriasis (Blauvelt 2008). Th17 cells secrete IL-17, IL-21 and IL-22, with the latter mediating IL-23 induced acanthosis and dermal inflammation (Zheng, Danilenko et al. 2007; Kunz 2009).Therefore, the IL-23/Th17 axis seem to play an important role in psoriasis and explains the hyperplasia of psoriatic keratinocytes (by IL-22), and why neutrophils appear in a chronic inflammatory disease, such as psoriasis (IL-8 production induced by IL-17) (Di Cesare, Di Meglio et al. 2009). More recently, functional interactions between IL-33 and mast cells were also found to contribute to inflammatory conditions, such as psoriasis (Xu, Jiang et al. 2008; Castellani, Kempuraj et al. 2009; Theoharides, Zhang et al. 2010). Nonetheless, the immunologic target molecule that would allow to classify psoriasis as an autoimmune disease, as well as, the events that trigger the inflammatory process, remain to be determined. Patients with psoriasis require an individual management and long-term planning of therapeutic strategies. The ratio risk versus benefit, and the cost-effectiveness of the different treatments should be carefully evaluated. The therapy is chosen in accordance with skin type, clinical history, patient's age, severity of psoriasis and the response to previous treatments. Topical agents are, usually, chosen for milder forms and limited psoriasis; phototherapy, photochemotherapy and systemic agents for moderate and severe psoriasis. Biological therapies, the more recent therapies for psoriasis, are particularly used for severe psoriasis. 2. Epidemiology Psoriasis affects about 125 million of people worldwide (National Psoriasis Foundation), is common in Caucasians and affects equally men and women. The prevalence of psoriasis in the population of Northern Europe and Scandinavia is 1.5-3%. While relatively common in Japanese, it is less common in Chinese, Eskimos, West Africans and North American blacks, and very uncommon in North American and South American natives and aboriginal Australians (Langley, Krueger et al. 2005). The causes for these variations are likely to be genetical and environmental; actually, population-based and twin studies indicate psoriasis as an heritable disease with a polygenic mode of inheritance, with variable penetrance (Elder, Nair et al. 1994). The prevalence of psoriasis seems to be affected by latitude (Vazquez, Carrera et al. 2006). The onset of psoriasis can be at any time of life and, afterwards, it usually persists for life. The mean age of onset of psoriasis vulgaris is at 33 years, and 75% of the patients develop psoriasis before 46 years of age (Nevitt and Hutchinson 1996). It has been also suggested that psoriasis onset is bimodal, with a peak at 16-22 and the other peak at 57-60 years of age. The age of onset is slightly earlier in women than in men. Psoriasis is a relapsing disease, although natural remission occurs in about one-third of the psoriatic patients (Farber and Nall 1974).

The assessment of the severity of psoriasis is often subjective because of the lack of quantitative laboratory diagnostic tools. Histopathological examination is the most commonly performed procedure for psoriasis diagnosis; however, it is usually descriptive. Thus, there is currently no quantitative method of determining psoriasis severity. The clinical types of psoriasis are correlated with the severity of the disease, and a lesional severity index, such as the psoriasis severity index (PSI), could be used as a quantitative tool for assessing gross severity. To correlate the histopathological findings of psoriasis with the PSI. Psoriatic lesions in 98 patients were evaluated. The lesions were classified into the guttate, papular, small plaque, and large plaque types according to morphology, and were scored according to the PSI. Ten common histopathological features of psoriasis were evaluated for correlation with gross severity. The clinical types of psoriasis showed significant c...

Psoriasis and its comorbidities
Journal of Pakistan Association of Dermatology, 2018
Objective To study the relation between psoriasis and its associated comorbidities i.e. obesity, hypertension, hyperlipidemia, diabetes, thyroid abnormalities. Methods This was a case-control study, including 150 patients and 50 age-and gender-matched controls visiting dermatology department. Detailed history was taken and clinical examination was done on enrolled patients according to the clinical proforma. Investigations like complete blood picture, thyroid profile, homocysteine levels, lipid profile and fasting blood sugar levels were done. Results Patients' mean age was 45.56±17.600 years in cases group whereas in control group was 46.060±19.659 years, P=0.868. The predominant clinical presentation was of plaque psoriasis. We found an increased prevalence of waist circumference, BMI, hypertension (systolic and diastolic), serum homocysteine and smoking. There was no statistically significant difference in HDL cholesterol, total cholesterol, fasting blood sugar, thyroid stimulating hormone, serum vitamin B12 and alcohol intake, among cases and control group. Conclusion Psoriasis is associated with numerous comorbidities that have a major impact on patients. In our study, we found significant association with obesity, hypertension, serum homocysteine and increased prevalence of smoking in patients with psoriasis. There are limited number of studies and data in Indian population for co-morbidities in psoriasis and much more studies and research are required to study such associations in Indian population.
