The changing epidemiology of gout

Area of Science:

• Rheumatology
• Epidemiology
• Crystal Deposition Disorders

Background:

• Gout is a prevalent inflammatory arthritis characterized by monosodium urate crystal deposition.
• Epidemiological studies indicate a rising prevalence and incidence of gout globally.
• The clinical presentation of gout is becoming increasingly complex.

Purpose of the Study:

• To review the epidemiological trends and risk factors associated with gout.
• To discuss factors contributing to the increasing complexity of gout cases.
• To highlight the role of suboptimal management in the rise of chronic gout.

Main Methods:

• Review of epidemiological studies on gout prevalence and incidence.
• Analysis of established risk factors for gout.
• Discussion of factors influencing gout complexity in clinical settings.

Main Results:

• Gout prevalence and incidence are increasing, with a notable rise in primary gout among older men.
• Key risk factors identified include genetics, alcohol, diet, metabolic syndrome, diuretics, and renal failure.
• Increased longevity contributes to osteoarthritis, potentially predisposing to gout.
• Widespread diuretic use and end-stage renal failure increase clinical complexity in hospital settings.

Conclusions:

• Changes in lifestyle factors like diet and alcohol consumption, along with the metabolic syndrome, likely drive the increase in gout.
• An aging population and advancements in medical care contribute to more complex gout cases.
• Suboptimal gout management is a significant factor in the growing prevalence of symptomatic, chronic gout.
