Wun","doi":"10.1111/jvim.70033","DOIUrl":"https://doi.org/10.1111/jvim.70033","url":null,"abstract":"&lt;p&gt;I thank Biourge et al. for their response to my letter and for highlighting the importance of early chronic kidney disease (CKD) diagnosis in cats. However, I am disappointed that the authors have elected not to disclose the number of cats with a baseline serum creatinine concentration between 1.6 and 1.9 mg/dL included in the testing dataset, on the basis that all cats “were healthy based on history and physical examination and had serum creatinine concentrations below the diagnostic threshold for CKD according to the reference interval of the laboratory used, and thus did not have a diagnosis of CKD at the time of screening.” The authors cite a 2019 International Renal Interest Society (IRIS) article, which states that cats with a serum creatinine concentration reaching the threshold for stage 2 CKD but within the laboratory reference interval must also have other independent evidence of CKD before a diagnosis can be made, to minimize the potential for false positive diagnoses [&lt;span&gt;1&lt;/span&gt;]. Since this article was written, it has been shown that a serum creatinine concentration &gt; 1.76 mg/dL has a 92.9% and 90.9% specificity for borderline-low and low glomerular filtration rate (GFR) in cats, respectively [&lt;span&gt;2&lt;/span&gt;]. Although the specificity of a &gt; 1.5 mg/dL creatinine cutoff was not provided in this study, an older article reports a specificity of 73% for the detection of a GFR ≤ 70% of normal [&lt;span&gt;3&lt;/span&gt;]. Furthermore, current IRIS guidelines state that CKD may be diagnosed based on the sole finding of a serum SDMA persistently &gt; 14 μg/dL [&lt;span&gt;4&lt;/span&gt;], which has a 75.0% and 75.7% specificity for a borderline-low and low GFR in cats, respectively [&lt;span&gt;2&lt;/span&gt;]. If this level of specificity is considered acceptable, it stands to reason that a serum creatinine concentration &gt; 1.5 mg/dL (although ideally &gt; 1.76 mg/dL) should also be sufficient.&lt;/p&gt;&lt;p&gt;Accordingly, Biourge et al.'s suggestion that diagnosing a cat with CKD based on a sustained serum creatinine concentration between 1.6 and 1.9 mg/dL (especially with a urine specific gravity ≤ 1.035) represents “a common misconception about the IRIS staging system,” and their following statement that these cats “are at a stage where plasma creatinine concentration is still within the laboratory reference interval and would thus be considered as normal in a regular senior screening” appears misguided. I am also not sure that their opinion is widely shared, with various key opinion leaders stating that CKD or renal azotemia in cats be considered with a serum creatinine concentration ≥ 1.6 mg/dL [&lt;span&gt;5-7&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;I again urge Biourge et al. to share the aforementioned data from their study. If cats with a baseline serum creatinine concentration between 1.6 and 1.9 mg/dL were considered “healthy,” their model might simply be predicting the likelihood that cats with early IRIS stage 2 CKD progress to a serum creatinine concentration ≥ 2.0 mg/dL within the subs","PeriodicalId":49958,"journal":{"name":"Journal of Veterinary Internal Medicine","volume":"39 2","pages":""},"PeriodicalIF":2.1,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/jvim.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143632746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our answer did focus on the rationale of our model, which was intended to predict as accurately as possible which cats would progress to azotemic CKD within 12 months of the initial screening in field conditions. We have expanded upon our previous reply in this letter.&lt;/p&gt;&lt;p&gt;Defining what constitutes early kidney disease is not straightforward, and key opinion leaders from the IRIS group offer a number of possible definitions, no doubt because none of these on their own is perfect. In our study, we took the approach of using a subsequent conventional diagnosis of azotemic CKD (based on our laboratory's reference interval for serum creatinine concentration together with USG &lt; 1.035) within 12 months of a single screening event to indicate that, at the screening event, the cat had subclinical early CKD. In our opinion, this is an unambiguous definition of early CKD, whereas most other ways of defining early CKD, without subsequent follow-up confirming a conventional diagnosis of CKD, carry a degree of uncertainty about whether these cats will continue to lose kidney function over time.&lt;/p&gt;&lt;p&gt;Dr. Wun cites Brans et al. (2021) as evidence that a serum creatinine concentration of 1.76 mg/dL has a 92.9% specificity for borderline low GFR (&lt; 1.7 mL/kg/min). This study, which focused on comparing the ability of serum SDMA and creatinine concentrations to identify cats with “borderline low GFR,” included 17 clinically healthy cats with no mention of how their kidney function progressed over time. The “borderline low GFR” definition was based on a previously published study from the same group, which involved 16 healthy clinically normal cats. Such small numbers would not be sufficient to establish a robust reference interval, and using this data to define a cutoff value of serum creatinine concentration with a given sensitivity and specificity to diagnose CKD early seems flawed to us.&lt;/p&gt;&lt;p&gt;Measurement of GFR in clinical practice is laborious and, despite a number of published studies, what constitutes a normal GFR and the variations that occur in a large population of healthy cats are not well defined. If it were, the IRIS group would have adopted GFR to define the stages of CKD and thus better define the non-azotemic stages. Importantly, the variation in GFR within the same cat when measured multiple times remains to be clearly defined. This variation needs to be understood before serial GFR measurements could be used to document deteriorating kidney function over time in early-stage CKD.&lt;/p&gt;&lt;p&gt;Our study was designed to help veterinarians in primary care practice make better use of health screening data to identify cats with a high likelihood of developing azotemic CKD within 12 months of a single visit.
