Takeaway

  • Patients with psoriasis were at a much higher risk for obstructive sleep apnea (OSA).

Why this matters

  • Psoriasis may be an independent risk factor for OSA.

Study design

  • The researchers conducted a case-controlled study of 253 consecutive in-hospital patients with OSA (200 men) at a single institution in Greece. They were compared with 104 control participants from the same hospital who came for an annual checkup.
  • Funding: None.

Key results

  • Patients with psoriasis had a greatly increased risk for OSA (OR, 13.31; P=.04).
  • There was no association between presence of psoriasis and severity of OSA.

Limitations

  • The study cannot prove causation.
