The Association of Alcohol Use Disorder and Chronic Plaque Psoriasis: Results of a Pilot Study.

BACKGROUND

Association between alcohol consumption, alcohol use disorder, and clinical features of psoriasis patients has not been adequately studied in the Indian context.

OBJECTIVES

To study the frequency of alcohol consumption, alcohol use disorder, and its association with age, gender, duration, and severity of psoriasis.

MATERIALS AND METHODS

One hundred and forty-six (M: F 6.3:1) patients completed the Alcohol Use Disorder Identification Test (AUDIT) questionnaire by World Health Organization (WHO). Excessive drinkers, occasional drinkers, and abstainers were defined. AUDIT provided a measure of alcohol consumption, its dependence, and its impact on daily life. The severity of psoriasis was graded as mild, moderate, and severe.

RESULTS

Seventy-four (50.7%) patients were aged ≤40 years and 51.4% of patients had the disease for <5 years. Psoriasis was mild in 48.6% and moderate to severe in 51.4% of patients, respectively. Only males (32.9%) were consuming alcohol in varying amounts; 19.9% were occasional drinkers (AUDIT score <8). Other 67.1% of patients completely abstained from alcohol consumption (AUDIT score 0). The remaining 13% were regular drinkers (AUDIT score >8) and had more severe psoriasis compared to patients having AUDIT score <8 ( < 0.05). A high level of alcohol use disorder and alcohol dependence was present in one patient each.

LIMITATIONS

Few patients, particularly females may not have disclosed their alcohol consumption due to fear of stigmatization. Small number of patients, hospital-based cross-sectional study design, and no follow-up for clinical improvement after cessation of alcohol are other limitations.

CONCLUSIONS

Alcohol consumption was associated with alcohol use disorder in 32.9% of patients (AUDIT score >8) and significantly severe psoriasis compared to 67.1% abstainers. Whether increased alcohol consumption is a consequence or a risk factor for chronicity of psoriasis needs large linear studies for confirmation.
