Nutritional intervention with branched-chain amino acid (BCAA) can increase serum albumin concentration in patients with decompensated cirrhosis but its effects on survival are unclear. The BCAA to tyrosine ratio (BTR) is a surrogate marker (the normal range of BTR is between 4.41 and 10.05, and a Fischer's ratio of 1.8 corresponds to a BTR of 3.5) in patients with decompensated liver cirrhosis, and BCAA inhibits hepatic carcinogenesis in patients with compensated cirrhosis. This review discusses data regarding the effect of early administration of BCAA granules based on the ratio of BCAA to BTR on prognosis in patients with cirrhosis.展开更多

Method: This study employed a retrospective case analysis, dividing patients into two groups: 16 cases with uric acid levels less than 50 μmol/L (group Level 1), and 240 cases with uric acid levels between 50 μmol/L and 119 μmol/L (group Level 2). Basic data such as age, gender, department, and clinical diagnosis were collected for each patient. Renal indices, including creatinine, urea, β2-microglobulin, and cystatin C, were analyzed and compared. Results: The highest percentage of patients with uremia was found in Level 1, with a rate of 31.25%. In Level 2, the highest percentage of patients had malignant tumors, with a rate of 15.41%. Tumor sites included the liver, lungs, endometrium, ovaries, breasts, stomach, pancreas, colon, hypopharynx, and others. The second highest percentage was 13.75% for patients with lung diseases, followed by 10% for patients with cranio-cerebral diseases. Other prevalent conditions included renal diseases, hematological diseases, multiple injuries, orthopedic diseases, rheumatological-immunological diseases, and cardiac diseases. There were significant differences between the two uric acid level groups in terms of prevalent diseases (P < 0.05). Additionally, gender differences were significant between the two groups (P < 0.05). However, for renal disease indicators, no significant differences were found between the two levels (P > 0.05). Conclusion: The types of diseases presented by patients were related to different low uric acid levels. Most patients‘ renal function indices were within normal reference ranges at different low uric acid levels. The prevalence of different low uric acid levels was related to gender.展开更多

This study aimed to explore whether SUA was a predictor of microalbuminuria and impaired renal function in type 2 diabetes in Chinese patients. Methods This cross-sectional study included 2108 type 2 diabetic patients. Kidney function was estimated using the simplified modification of diet in renal disease （MDRD） equation to obtain estimated glomerular filtration rate. The urine samples were obtained for measuring the albumin-to-creatinine ratio （ACR）. Results According to the ACR level, these patients were divided into two groups, normal ACR （NA） and non-normal ACR （non-NA）. Both SUA and creatinine were significantly higher in the non-NA group than those in the NA group （（318.89±107.52） vs. （283.44±88.64） pmol/L, and （95.08±53.24） vs. （79.63±18.20） μmol/L, respectively）. Logistic regression analysis showed that diabetic duration, systolic blood pressure, creatinine and SUA were the independent predictors of albuminuria. Furthermore, to identify the factors associated with renal function, these patients were divided into two groups according to the MDRD level （MDRD〈90 or MDRD〉90）. Both SUA and creatinine were significantly higher in the lower MDRD group than those in the higher MDRD group （（301.90±96.46） vs. （264.07±84.74） μmol/L, and （89.10±31.00） vs. （66.37±11.15） μmol/L, respectively）. Logistic regression analysis showed that only age and SUA were the independent predictors of MDRD. Conclusion High-normal SUA was associated with albuminuria and impaired glomerular filtration rate in Chinese type 2 diabetic patients.展开更多
