Hyperuricemia is the term for an abnormally high serum uric acid level. Many factors contribute to hyperuricemia, however no definite correlation between proton pump inhibitors (PPIs) and hyperuricemia has been reported before. Physical exercise also decreases serum uric acid levels. However, the detailed biochemical-regulatory mechanisms remain unknown. Here we found that adenylate deaminase activities are much higher in hyperuricemia patients than in the healthy people. Therefore, the patients have higher levels of adenosine metabolites hypoxanthine and uric acid. Acid-inhibitory drugs (antacids) significantly increased serum uric acid level and may lead to gout in the hyperuricemia patient. Long-term aerobic exercise significantly increased serum phosphorus and decreased serum ATP and its metabolites, and therefore decreased serum uric acid. Antacids slow down the ATP turnover rate and result in serum uric acid elevation subsequently. While the long-term aerobic exercise decreases serum uric acid levels by accelerating ATP turnover rate. The results imply that long-term aerobic exercise may be a useful strategy to prevent and treat hyperuricaemia.
高尿酸血症是指血清尿酸水平异常升高。许多因素可导致高尿酸血症,但以前没有报道质子泵抑制剂 (PPI) 与高尿酸血症之间存在明确的相关性。体育锻炼也可降低血清尿酸水平。然而,详细的生化调节机制尚不清楚。在这里,我们发现高尿酸血症患者的腺嘌呤脱氨酶活性明显高于健康人。因此,患者的腺嘌呤代谢物次黄嘌呤和尿酸水平较高。抑酸药物(抗酸剂)可显著升高血清尿酸水平,并可导致高尿酸血症患者痛风发作。长期有氧运动可显著升高血清磷,降低血清 ATP 及其代谢物,从而降低血清尿酸。抗酸剂可降低 ATP 周转率,从而导致血清尿酸升高。而长期有氧运动则通过加速 ATP 周转率来降低血清尿酸水平。结果表明,长期有氧运动可能是预防和治疗高尿酸血症的有效策略。
