To assess whether psoriasis comorbidities modify the disease.
Material and Methods
In 170 patients with psoriasis, we considered the following comorbidities: hypertension, metabolic syndrome, diabetes, dyslipidemia, overweight, cardiovascular disease, liver disease, and thyroid diseases. We compared patients with any number of comorbidities to patients without comorbidities, and we also compared patients with one, two, or three or more comorbidities to patients who lacked comorbidities.
Results
We identified 62 patients (36%) without comorbidities and 108 patients (64%) with comorbidities. Only age, duration of the disease, and guttate psoriasis showed statistically significant correlation with comorbidities. When the group without comorbidities was compared with the groups of patients with differing numbers of comorbidities, we found significant differences only in age and duration of the disease.
Conclusions
The presence and the increased number of comorbidities were associated with advanced age and greater duration of the disease, whereas guttate psoriasis had an inverse relation with concomitant diseases.
