Objective:
To determine the risk of fracture and osteoporosis among patients with psoriatic arthritis (PsA) and psoriasis, compared with the general population and patients with rheumatoid arthritis (RA).
Methods:
A population-based cohort study was performed in The Health Improvement Network in the UK using data from 1994 to 2014. Patients aged 18-89 years with PsA or psoriasis and up to five unexposed controls matched by practice and start date within that practice were included. Patients with RA and matched controls were included for comparison. Severe psoriasis was defined by a code for psoriasis and either phototherapy or a systemic medication for psoriasis. Incidence and adjusted HRs (aHR) for fracture (all, hip, vertebral) were calculated.
Results:
Patients with PsA (n=9788), psoriasis (n=158 323) and controls (n=821 834) were identified. Patients with PsA had an elevated risk of all fracture aHR 1.26 (1.06 to 1.27). Patients with mild psoriasis had elevated risk of all fractures, vertebral and hip fracture: aHR 1.07 (1.05 to 1.10), 1.17 (1.03 to 1.33) and 1.13 (1.04 to 1.22). Patients with severe psoriasis had significantly elevated risk of all fracture and vertebral fracture: aHR 1.26 (1.15 to 1.39) and 2.23 (1.54 to 3.22).
Conclusions:
PsA and psoriasis are associated with an elevated risk for fracture.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
Factors Affecting the Risk of Infection
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...
