New developments in ochronosis: review of the literature

Abstract: Ochronosis commonly affects all connective tissue. Recognition of changes secondary to the deposition of ochronotic pigments has increased with advances in diagnostic technology, allowing both improved imaging and early biochemical and genetics-based diagnosis of alkaptonuria, the cause of ochronosis. Successful symptomatic treatment of ochronotic arthropathy with joint replacement has been documented, and a new pharmacotherapeutic agent, nitisinone, is currently under investigation for both prevention and tre… Show more

“…HGA is a reducing agent and was detected by: silver nitrate test (brown-black precipitate), Benedict's test (initial greenish precipitate followed by a yellow precipitate of cuprous oxide) and ferric chloride test (transient blue-green colour). HGA was elevated in 24-hr urine by spectrophotometric analysis (8,9). The normal urinary HGA levels are less than 11 mmol/mol creatinine (10).…”
