The Level of Urine Dipstick Proteinuria and Its Relation to the Risk of Incident Cholelithiasis.

ABSTRACT:

Background

Previous studies have suggested the potential association between renal diseases and gallstone. The extent of proteinuria is recognized as a marker for the severity of chronic kidney disease. However, little data is available to identify the risk of incident gallstone according to the level of proteinuria.

Methods

Using a data of 207,356 Koreans registered in National Health Insurance Database, we evaluated the risk of gallstone according to the levels of urine dipstick proteinuria through an average follow-up of 4.36 years. Study subjects were divided into 3 groups by urine dipstick proteinuria (negative: 0, mild: 1+ and heavy: 2+ or greater). Multivariate Cox-proportional hazard model was used to assess the adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident cholelithiasis according to urine dipstick proteinuria.

Results

The group with higher urine dipstick proteinuria had worse metabolic, renal, and hepatic profiles than those without proteinuria, which were similarly observed in the group with incident cholelithiasis. The heavy proteinuria group had the greatest incidence of cholelithiasis (2.39%), followed by mild (1.54%) and negative proteinuria groups (1.39%). Analysis for multivariate Cox-proportional hazard model indicated that the heavy proteinuria group had higher risk of cholelithiasis than other groups (negative: reference, mild proteinuria: HR 0.97 [95% CI, 0.74-1.26], and heavy proteinuria: HR 1.46 [95% CI, 1.09-1.96]).

Conclusion

Urine dipstick proteinuria of 2+ or greater was significantly associated with increased risk for incident gallstone.

Project description:BACKGROUND AND OBJECTIVES:The natural history of kidney disease among blacks who carry the APOL1 high-risk variants varies, with only a subgroup progressing to ESRD. We aimed to determine whether the APOL1 risk variants are associated with incident proteinuria in the context of hypertension-attributed CKD, and whether subsequent kidney function decline after the onset of proteinuria differs by APOL1 risk status. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS:Using Cox models, we studied the association between APOL1 risk status and incident proteinuria (defined as a doubling of urine protein-to-creatinine ratio to a level ≥0.22 g/g creatinine) among African-American Study of Kidney Disease and Hypertension (AASK) trial participants with APOL1 genotyping and without proteinuria at baseline. RESULTS:Of the 480 participants in our study, 82 (17%) had the high-risk genotypes (2 alleles), and 254 (53%) developed proteinuria over a median follow-up of 6.8 years. At baseline, mean eGFR was lower in the APOL1 high-risk group compared with the low-risk group (0 or 1 allele; 49.6 versus 53.2 ml/min per 1.73 m2, respectively; P=0.02), but median proteinuria was similar (0.04 g/g creatinine for both groups; P=0.43). Individuals with the high-risk genotypes were 1.72-fold more likely to develop incident proteinuria compared with those with the low-risk genotypes (95% confidence interval, 1.27 to 2.32), independent of age, sex, ancestry, baseline eGFR, baseline systolic BP, and randomized treatment groups. Although eGFR declined faster after the onset of proteinuria, this rate did not differ significantly by APOL1 risk status. CONCLUSIONS:Among blacks with established moderate CKD, the APOL1 high-risk variants are associated with greater risk of incident proteinuria. After proteinuria onset, kidney function declines more rapidly but does not differ by APOL1 risk status. This suggests that factors that lead to proteinuria, beyond APOL1, may additionally drive CKD progression.
