Onset of HLA-B27-associated diseases in diabetic patient during a period of religious fasting: A case report.

RATIONALE: The association between human leukocyte antigen B27 (HLA-B27) with its associated diseases is far from complete. The role of HLA-B27 in disease susceptibility is still not known, although many suggestions have been proposed.

PATIENT CONCERNS: The patient was a 46-year-old policeman with a history of obesity, diabetes, and hypertension. He was a Shaolin lay disciple who fasted at the Shaolin temple for at least 1 week each year since 2014.

DIAGNOSES: The patient suffered three different HLA-B27-associated diseases including acute anterior uveitis, ulcerative colitis, and ankylosing spondylitis, from 2014 to 2016 because of prolonged fasting.

INTERVENTIONS: The patient accept standard treatment after the diagnosis of acute anterior uveitis, ulcerative colitis, and ankylosing spondylitis.

OUTCOMES: The patient's symptoms and signs of acute anterior uveitis, ulcerative colitis, and ankylosing spondylitis were all relieved within one week after the clinical treatment.

LESSONS: Our case suggested that prolonged fasting may lead to the onset of HLA-B27-associated diseases in diabetic patient.
