Gout, an inflammatory arthritis caused by high urate levels in the blood (SU), is associated with medical issues, including heart disease, high blood pressure, type 2 diabetes, and kidney disease. Millions of Americans have gout, with some having early-onset gout (EOG), generally the first gout attack at or before 40 years of age. Little information on EOG has been published; this literature review provides insight. More recent articles and major rheumatology meeting presentations (2016 to August 2022) on EOG were reviewed. Publications that were duplicates, not in English, on a single patient, or were not relevant/did contain enough information were excluded. The age at gout diagnosis determined if patients had common gout (CG) or EOG. Of the 283 publications identified, 17 were included in this review. Gout-associated medical issues (heart, metabolic, and kidney-related) were less common in EOG than CG patients and occurred after gout diagnosis in EOG patients. Compared to CG patients, EOG patients more often had severe gout (more gout attacks and affected joints), higher SU, and worse response to oral SU-lowering medications. Genetics-focused publications showed that mutations affecting how urate is removed from the body are more common in EOG patients. Overall, the literature suggests that EOG may be difficult to treat, has a genetic component, and has a heavy disease burden. Therefore, early rheumatology referral and gout management may benefit EOG patients due to a potential "window of opportunity" where proper SU control may prevent gout-related suffering and health burden in young EOG patients who will live with gout and its consequences for decades.
