Patients with calcium kidney stones also have higher risk of developing diabetes compared with nonkidney stone patients yet this has not been further investigated. We aimed to characterize insulin resistance in calcium kidney stone patients.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Study Design&lt;/h3&gt;&lt;div&gt;Observational.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Setting &amp; Population&lt;/h3&gt;&lt;div&gt;This study was performed in the University of Chicago Clinical Research Center. Kidney stone patients (N&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;42) were selected for having idiopathic hypercalciuria and calcium stones with no other medical conditions, and controls (N&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;27) were healthy.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Exposures&lt;/h3&gt;&lt;div&gt;All participants presented to the Clinical Research Center in a fasting state and at least 2 timed fasting blood and urine collections were collected before a fixed breakfast. Six additional timed blood and urine collections were performed after breakfast.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Outcomes&lt;/h3&gt;&lt;div&gt;We compared fasting and fed indices of insulin resistance between the groups.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Analytic Approach&lt;/h3&gt;&lt;div&gt;We used &lt;em&gt;t&lt;/em&gt; tests and multivariable linear regression models. A sensitivity analysis removing all patients who had ever been on a thiazide diuretic was also performed.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Results&lt;/h3&gt;&lt;div&gt;In separate multivariable linear models, kidney stone patients had higher fasting serum insulin levels (24 (3-46&lt;!--&gt; &lt;!--&gt;pmol/L), &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.03) and higher homeostatic model of insulin resistance (HOMA-IR) (1.0 (0.2-1.8), &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.02). In separate multivariable linear models, kidney stone patients had higher fed serum glucose levels (10 (2-18&lt;!--&gt; &lt;!--&gt;mg/dL), &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.01). Results were similar in a sensitivity analysis removing all patients who had ever been on a thiazide diuretic. There were no differences in urine composition based on HOMA-IR levels.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Limitations&lt;/h3&gt;&lt;div&gt;Single institution. Small sample size limited subanalyses by different calcium stone types.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;Calcium kidney stone patients without diabetes or other medical conditions demonstrated signs of insulin resistance compared with healthy matched controls.&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Plain-Language Summary&lt;/h3&gt;&lt;div&gt;Diabetes is strongly associated with kidney stones, particularly uric acid kidney stones. However, patients who form calcium kidney stones may also have an increased risk of developing diabetes, but this has not been further explored. We collected markers of insulin resistance in otherwise healthy patients with calcium kidney stones and healthy control volunteers to evaluate for early signs of insulin resistance in patients with calcium kidney stones. Compared to healthy control participants, we found that patients with calcium kidney stones are more likely to have ins","PeriodicalId":17885,"journal":{"name":"Kidney Medicine","volume":"6 12","pages":"Article 100922"},"PeriodicalIF":3.2,"publicationDate":"2024-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142654847","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
