Acute Intermittent Porphyria in the North of China: The Acute Attack Effect on Quality of Life and Psychological Condition.

BACKGROUND

Acute intermittent porphyria (AIP) is an autosomal recessive disorder with intermittent attacks. Patients with AIP are susceptible to impaired quality of life and psychological distress.

OBJECTIVES

To document the clinical features of AIP and its impact on SF-36 and IES scores of AIP patients in China and to explore the variables associated with SF-36 and IES scores.

METHODS

A single investigator collated data related to treatments and outcomes in 27 patients with AIP of PUMCH. A cross-sectional questionnaire survey including the SF-36, the IES-R, and demographic questions was conducted in the north of China. Differences in the QoL scale/summary scores and proportions in the QoL dimensions between patients and the general population were analyzed. Independent effects of chronic conditions and demographic variables on the SF-36 and IES-R were analyzed.

RESULTS

AIP patients had considerably lower SF-36 scores than the general population (the PF score and MH were lower than normal, < 0.05). Working had higher RP than staying at home ( = 0.02); "without acute attack" had higher PF and BP scores and PCS composite score ( = 0.001). The mean IES-R score of AIP was higher than normal (36.7 ± 11.8 points, < 0.001), "without acute attack" had lower intrusion score than "with acute attack" ( = 0.03).

CONCLUSION

AIP patients in China had impaired quality of life, especially in terms of physical health. The acute attacks coursed the posttraumatic stress disorder-related symptoms.
