Introduction:

In recent years, various investigations have shown that the presence of comorbidity worsens the prognosis of patients with psoriatic arthritis.

Objective:

To determine the comorbidities in patients diagnosed with psoriatic arthritis.

Methods:

A descriptive cross-sectional study was conducted in the Rheumatology service of the “Hermanos Ameijeiras” Clinical-Surgical Hospital, which included 111 patients with psoriatic arthritis from January 2016 to February 2018.

Results:

The age group most represented was that of 50 to 60 years, female sex (63.1%) and white skin color (77.5%) patients predominated. 50.5% had a psoriatic arthritis evolution time greater than 10 years. 94.5% expressed the peripheral joint pattern and the most frequent joint clinical form was oligoarticular (56.7%). The most frequently identified comorbidities were obesity (80.18%), dyslipidemia (68.46%), arterial hypertension (HBP) (54.95%) and non-alcoholic fatty liver (53.15%). 73.0% had three or more comorbidities. The sex and the time of evolution of the disease and the inflammatory activity did not show significant relationship. The inflammatory activity of the disease was demonstrated in 83.8%.

Conclusions:

The presence of associated comorbidities was evidenced in patients with PsA, with obesity, dyslipidemia, hypertension, and non-alcoholic fatty liver occurring more frequently. A high percentage of patients had more than three comorbidities and no significant association was demonstrated between the number of comorbidities and disease variables.
