INTRODUCTION
PSORIASIS
Psoriasis is one of the most common dermatologic diseases, affecting upto 2% of the world’s population.(1)It is an immune mediated disease clinically characterised by erythematous sharply demarcated papules and rounded plaques covered by silvery micaceous scale. The skin lesions of psoriasis are variably pruritic .

PG Department of Medicine MLN Medical College and S.R.N. Hospital Allahabad
(1)Psoriasis is histologically characterized by epidermal hyperplasia, abnormal keratinocyte differentiation, proliferation of dermal blood vessels, and accumulation of inflammatory cells, particularly neutrophils and T-lymphocytes in the dermis.(2) More than skin disease, psoriasis is nowadays considered a systemic inflammatory disorder(3),It is associated with numerous metabolic disorders like obesity, dyslipidemia, Type 2DM and hypertension.(4,5)The strict clinical connection between psoriasis and metabolic diseases are well explained by analogies in their pathogenesis(chronic inflammation)viewing active factors secreted by adipose tissue (adipocytokines) and insulin resistance.(6)
METABOLIC DISEASES TYPE 2 DIABETES MELLITUS(T2DM)- Diabetes mellitus
refers to a group of common metabolic disorders that share the phenotype of hyperglycemia. T2DM is a long term metabolic disorder that is characterized by high blood sugar, insulin resistance, and relative lack of insulin. Insulin resistance and abnormal insulin secretion are central to pathogenesis of type 2 diabetes mellitus. Insulin resistance precedes an insulin secretory defect but diabetes develops only when insulin secretion becomes inadequate. Approximately 425 million adults are living with diabetes. (7) The proportion of people with type 2 diabetes is increasing in most countries.(7)Insulin resistance and abnormal insulin secretion are central to the development of type 2 DM.(8)
OBESITY-Obesity is a state of excess adipose tissue mass.(9)Although not a direct measure of adipocity, it is most commonly measured by Body Mass Index(BMI).(9)Although the adipocyte has generally been regarded as a storage depot for fat, it is also an endocrine cell that releases numerous molecules in a regulated fashion.(10)These include cytokines such as tumour necrosis factor α(TNF-α),and interleukin(IL)-6,energy balance regulating hormone leptin, adiponectin etc.(10)
HYPERTENSION-According to 2017 ACC/AHA guideline hypertension is defined as systolic blood pressure >=130 mm of Hg and diastolic blood pressure >=80 mm of Hg.(11) In addition

to its metabolic effects,insulin induces vasorelaxation by stimulating the production of nitric oxide(NO) in the endothelium(12).It also regulates sodium homeostasis by enhancing sodium reabsorbtion in the kidney(13,14).Insulin has complex vascular actions that either appear as vascular protective or deletorious.
DYSLIPIDEMIA-Disorders of lipoprotein metabolism are collectively referred to as ‘dyslipidemias’(15) Dyslipidemia is characterised by increased plasma levels of cholesterol or triglycerides(TG) or both, variably accompanied by reduced level of High density lipoprotein(HDL).(15)Obesity and insulin resistance are frequently accompanied by dyslipidemia and are characterised by elevated plasma level of TG, low HDL-C and variable level of Low Density Lipoprotein (LDL-C ) and increased level of Very Low Density Lipoprotein (VLDL).(15)
Lipids Cut off values(mg/dl)
Total cholesterol >=200
LDL-C >=130
HDL-C <=40(Men);<=50(Women)
TG >=150

REVIEW OF LITERATURE
Many studies have been performed to evaluate the correlation between Psoriasis and different metabolic diseases. A case control study was conducted in Teerthanker Mahaveer Medical College, Moradabad, Uttar Pradesh ,India by Jain S.K et a on the topic “Metabolic syndrome in patients with chronic plaque psoriatic disease”, and used the students t-test, Mann Whitney U test and chi-square test to calculate the statistical significance and they concluded that metabolic syndrome in psoriasis was associated with higher age .Among the cases,64% had metabolic syndrome as compared to 48% of controls(p value-0.158).The mean for serum triglycerides(TG) level for psoriasis patients(159.42mg/dl) was higher than controls (144.25mg/dl).46% of cases had elevated TG>=150mg/dl as compared to 40% of controls.(16)
Another study was done by Mohammad Ebrahimzade et al on “Prevalence of Insulin resistance in patients with psoriasis” in Shahid Sadoughi University of Medical Sciences, Yazd, Iran, on 110 patients with psoriasis and equal no. of healthy people. The study design was case control and used chi-square test as statystical analysis and found out that the mean fasting plasma glucose was 106mg/dl in patient group and 103.93mg/dl in the control group, insulin resistance was found in 46.4% of patients(p-value:0.665)and 39.1% of controls(p-value:0.276). According to this study there was no association between insulin resistance and psoriasis.(17)
Jing-Ji et al, made a meta-analysis from 12 case control studies with a total of 3831 psoriatic patients to study the “Association between psoriasis and metabolic syndrome” in Tianjin First Centre Hospital, Tianjin, China. The results showed that metabolic syndrome was more prevalent in psoriatic patients than in controls. The odds ratio(OR) was 2.07[95% Confidence interval(CI)].It also demonstrated that higher prevalence of obesity and hypertension was found in psoriasis patients, the OR being 1.64 and 2.24 respectively. (18)
Another study was conducted by Doddaengaiah R. Shivanand et al,on “Insulin Resistsance and Dyslipidemia in Psoriasis Patients” which was a case control study. They studied on 52 psoriasis patients and 50 healthy control in Shridevi Institute of Medical Sciences and Research Hospital, Tumkur, Karnataka, India. They concluded that fasting insulin levels and insulin resistance measured by HOMA-IR method were significantly (p<0.05)higher in mild and severe psoriasis cases when compared to healthy controls. Total cholesterol, triacyl glycerol, LDL-cholesterol levels were significantly higher in mild and severe psoriasis

cases in comparision to controls. HDL-cholesterol levels were significantly lower in both mild and severe cases as compared to controls.(19)
According to another study conducted by April W.Armstrong et al, on “Psoriasis and risk of diabetes associated microvascular and macrovascular complications” in department of Dermatology, University of Colorado, Boston studied,Study was conducted on 6164 diabetic patients with psoriasis and matched them to 6164 diabetic patients without psoriasis and concluded that patients with psoriasis were significantly more likely to develop microvascular and macrovascular complications. Greater psoriasis severity did not increase the risk of diabetic complications.(20)
Sinead M.Langan et al studied on 4065 psoriasis patients and 4065 controls on the topic, “Metabolic syndrome in patients with psoriasis” in University of Pennsylvania, Philadelphia, Pennsylvania, USA . They concluded that Psoriasis is associated with obesity, hypertryglyceridemia and hyperglycemia. These associations increase in a ‘dose response manner’,from mild(OR 1.22,95% CI 1.11-1.35)to severe psoriasis(OR 1.98,95%CI 1.62-2.43).(21)
AIMS AND OBJECTIVES
To study prevalence of metabolic diseases in patients of psoriasis. To study prevalence of insulin resistance using HOMA-IR index in
patients of psoriasis.
IMPLICATIONS OF THE STUDY
To prompt for early diagnosis and management of diabetes, hypertension, obesity and dyslipidemic states in psoriatic patients.
