Abstract

Background: Psoriasis is a chronic and recurrent inflammatory disease that involves skin, joints and different organ systems. It is associated with Multiple morbidities such as cardiovascular disorders, diabetes, hypertension, hyperlipidemia and chronic kidney disease (CKD). Due to the high importance of the association between psoriasis and CKD which results in major side effects the aim of this study was to evaluation of CKD and associated factors in Psoriasis patients at Razi Hospital, Tehran, Iran. Methods: This retrospective study was conducted as a cross-sectional descriptive and analytical study to evaluate the frequency of CKD and associated factors in psoriatic patients admitted to the Razi Hospital whose last time of admission was from June 2018 to January 2019. According to the K/DOQI guideline, CKD is defined as the GFR<60 mL/min/1.73 m2 during at least a period of three months. GFR was calculated based on the MDRD formula. The sample size was equal to 265. The hospital documents of inpatients who have been admitted to Razi Hospital wards or follow-up clinics during 2017-2019 were used for collecting information and data. This information has been extracted based on the initial checklist for data collection. Collected data has been analyzed and performed by using SPSS 25 software. Results: The study found that 18 (6.8%) of psoriasis patients had CKD. Patients were in the age range of 3.5-92 years, the majority of them were in the age range of 18.65-79.7 years. 171 (64.5%) patients were male and 94 (35.5%) were female. 41 (15.5%) patients had diabetes, 94 (35.5%) had hyperlipidemia and 41 (15.5%) had hypertension. History of NSAID, Methotrexate, Cyclosporine, Acitretin, Infliximab, and Adalimumab medication use among 9 (3.4%), 205 (77.4%), 56 (21.1%), 147 (55.5%), 30 (11.3%), and 28 (10.6%) patients were observed, respectively. Also, 54 (20.4%) had a history of phototherapy. 217 (81.9%) of the psoriatic patients had CPP (Chronic Plaque Psoriasis) and 48 (18.1%) had PP (pustular Psoriasis) and finally, 21 (7.9%) of the patients had psoriatic arthritis. Conclusion: The prevalence of CKD was shown to increase by age. The other correlated factors are diabetes, hypertension, and hyperlipidemia. On the other hand, there was not found any significant correlation between drugs (NSAIDs, Methotrexate, Cyclosporine, Acitretin, Infliximab, Adalimumab) and CKD prevalence. There was also no significant correlation between phototherapy, psoriasis type and psoriatic arthritis, duration of psoriasis and CKD prevalence. © 2022 Tehran University of Medical Sciences.
