Patterns of Comorbidities in Psoriasis Patients: A Cross-Sectional Study

Background: Psoriasis is a chronic, inflammatory, and immune-mediated dermatological disease of unknown etiology with predominant involvement of the skin, nails, and joints. This study aimed to assess comorbidities patterns in psoriasis patients. Methods: This is a cross-sectional study conducted at King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Data were collected through a retrospective chart review of the electronic medical record system (Bestcare, Ezcaretech, Seoul, Korea) and by utilizing a structured data collection sheet. Results: A total of 128 confirmed psoriasis cases were included with a mean age of 44.2 ± 17.3. The sample had 45.7% females and 54.3% males. Nearly half the patients (46.1%) had no comorbidities, followed by those who had at least one comorbidity (24.2%) and those who had two or more comorbidities (29.7%). Most patients were classified as plaque psoriasis (57.0%), followed by those who had psoriatic arthritis (13.3%). There was no statistical significance between gender, body mass index (BMI), and smoking with the number of comorbidities (P= 0.422, P=0.361, P=0.772); 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which is statistically significant at p-value <0.018. Conclusion: This study demonstrated the prevalence of different comorbidities associated with psoriasis patients; 41.2% of psoriatic arthritis patients and all erythrodermic arthritis patients had two or more comorbidities, which was statistically significant. This necessitates closer monitoring of different comorbidities a psoriasis patient might present with. Especially those who are diagnosed with psoriatic arthritis and erythrodermic arthritis.
