Backgrounds: Few studies have reported the prevalence and characteristics of hypouricemia in the emergency department (ED). We investigated the prevalence and characteristics of hypouricemia in the ED of a university-affiliated hospital in Japan.
Methods: This is a retrospective cross-sectional single-center study. All adult patients (18 years old or older) who had their serum uric acid (SUA) measured at the ED between 2011 and 2021 were included. Information collected included age, sex, SUA, and serum creatinine. Hypouricemia was defined as an SUA level ≦2.0 mg/dL.
Results: A total of 10,551 patients were included in the study. Fifty-one percent were male. The median SUA levels were significantly higher in men than in women (6.0 [4.8-7.4] vs. 4.7 [3.7-6.1], < 0.001). The prevalence of hypouricemia was higher in women than in men (2.0% vs. 0.9%, < 0.001). A possible cause of hypouricemia was identified in 88 patients. Malignancy and diabetes were the major possible cause of hypouricemia ( < 0.001).
Conclusion: The distribution of SUA levels and prevalence of hypouricemia differed significantly by sex and age in the ED. Malignancy was the leading cause of hypouricemia in the ED.

Red yeast rice, traditionally used in Asian cuisine and increasingly marketed as a dietary supplement for cholesterol management, has recently been linked to kidney dysfunction in Japan. In late 2023 to early 2024, multiple cases involving specific Beni-koji (red yeast rice) tablets from three different Beni-koji preparations, prompted a safety reevaluation. Although citrinin, a known nephrotoxin of red yeast rice, was not produced by the implicated strains, new safety concerns emerged.

Article Synopsis
- Hypouricemia, characterized by a low serum uric acid level (≤2 mg/dL), may increase the risk of death in hospitalized patients, but its predictive factors were previously unclear.
- This study analyzed risk factors for hypouricemia in 618 patients at Yonago Medical Center using a Bayesian logistic regression model, identifying key independent risk factors.
- Results indicated that febuxostat and other factors like amino acids in parenteral nutrition, TMP-SMX, emaciation, and low serum sodium levels significantly contributed to the likelihood of hypouricemia.

Although some dietary supplements have been reported to cause renal dysfunction, there have been few reports of supplement-induced Fanconi syndrome. We present the case of a 56-year-old woman with Fanconi syndrome that developed after she consumed a red yeast rice supplement. She was referred to our hospital because of renal dysfunction, and was found to have electrolyte abnormalities, including hypophosphatemia and hypouricemia, renal diabetes, and hyperchloremic metabolic acidosis, and was, therefore, diagnosed with Fanconi syndrome.

Renal hypouricemia (RHUC) is a rare inherited disorder characterized by impaired urate reabsorption in the proximal tubule resulting in low urate serum levels and increased urate excretion. Some patients may present severe complications such as exercise-induced acute renal failure and nephrolithiasis. RHUC is caused by inactivating mutations in the (RHUC type 1) or (RHUC type 2) genes, which encode urate transporters URAT1 and GLUT9, respectively.
