End-stage renal disease secondary to autosomal dominant poly-cystic kidney (ADPKD) is a common issue worldwide. Peritoneal dialysis (PD) is a reasonable option for renal replacement therapy for these patients and should not be withheld due to concerns that the patient may not tolerate the fluid volumes in the peritoneal cavity. This review covers the existing data on the outcomes and complications associated with the use of PD in the polycystic kidney disease patient. In general, PD is well tolerated and outcomes in ADPKD patients are equivalent to or better than other patient groups.

Abstract Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by mutations of two genes, PKD1 and PKD2. In the presence of a positive family history of ADPKD, genetic testing is currently seldom indicated as the diagnosis is mostly based on imaging studies using well-established criteria. Moreover, PKD1 mutation screening is technically challenging due to its large size, complexity (i.e. presence of six pseudogenes with high levels of DNA sequence similarity) and extensive allelic heterogeneity. Despite these limitations, recent studies have delineated a strong genotype–phenotype correlation in ADPKD and begun to unravel the role of genetics underlying cases with atypical phenotypes. Furthermore, adaptation of next-generation sequencing (NGS) to clinical PKD genetic testing will provide a high-throughput, accurate and comprehensive screen of multiple cystic disease and modifier genes at a reduced cost. In this review, we discuss the evolving indications of genetic testing in ADPKD and how NGS-based screening promises to yield clinically important prognostic information for both typical as well as unusual genetic (e.g. allelic or genic interactions, somatic mosaicism, cystic kidney disease modifiers) cases to advance personalized medicine in the era of novel therapeutics for ADPKD.

Autosomal Dominant Polycystic Kidney

Abstract Background The ability to identify patients with autosomal dominant polycystic kidney disease (ADPKD) and distinguish them from patients with similar conditions in healthcare administrative databases is uncertain. We aimed to measure the sensitivity and specificity of different ADPKD administrative coding algorithms in a clinic population with non-ADPKD and ADPKD kidney cystic disease. Methods We used a dataset of all patients who attended a hereditary kidney disease clinic in Toronto, Ontario, Canada between 1 January 2010 and 23 December 2014. This dataset included patients who met our reference standard definition of ADPKD or other cystic kidney disease. We linked this dataset to healthcare databases in Ontario. We developed eight algorithms to identify ADPKD using the International Classification of Diseases, 10th Revision (ICD-10) codes and provincial diagnostic billing codes. A patient was considered algorithm positive if any one of the codes in the algorithm appeared at least once between 1 April 2002 and 31 March 2015. Results The ICD-10 coding algorithm had a sensitivity of 33.7% [95% confidence interval (CI) 30.0–37.7] and a specificity of 86.2% (95% CI 75.7–92.5) for the identification of ADPKD. The provincial diagnostic billing code had a sensitivity of 91.1% (95% CI 88.5–93.1) and a specificity of 10.8% (95% CI 5.3–20.6). Conclusions ICD-10 coding may be useful to identify patients with a high chance of having ADPKD but fail to identify many patients with ADPKD. Provincial diagnosis billing codes identified most patients with ADPKD and also with other types of cystic kidney disease.

End Stage

The spectrum of cystic kidney diseases encompasses a wide range of genetic syndromes with different identified disease genes, modes of inheritance, extrarenal organ manifestations, and clinical progression. Depending on the given disease gene and type of mutation in a respective cystic kidney disease, the age of onset, pathologic characteristics, and rate of progression to end-stage kidney disease vary considerably. This review covers disease definitions, etiology and genetics, pathophysiology and pathogenesis, diagnosis, differential diagnosis, and treatment of cystic kidney disease. Additionally, simple and complex renal cysts in adults are discussed. Tables list the epidemiology of polycystic kidney disease, gene locus, and encoded protein, unified criteria for ultrasonographic diagnosis of autosomal dominant polycystic kidney disease (APDKD), risk factors for progressive kidney disease in APDKD, differential diagnosis of cystic diseases of the kidney, Halt Progression of Polycystic Kidney Disease trial summary, and other extrarenal manifestations of ADPDK.

Autosomal Dominant Polycystic Kidney

<b><i>Background:</i></b> Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary cystic kidney disease and is well known to have extrarenal complications. Cardiovascular complications are of particular clinical relevance because of their morbidity and mortality; however, unclear is why they occur so frequently in patients with ADPKD and whether they are related to the genotypes. <b><i>Methods:</i></b> We extracted and retrospectively analyzed clinical data on patients with ADPKD who underwent echocardiography and whose genotype was confirmed by genetic testing between April 2016 and December 2020. We used next-generation sequencing to compare cardiac function, structural data, and the presence of cardiac valvular disease in patients with 1 of 3 genotypes: <i>PKD1</i>, <i>PKD2</i>, and non-<i>PKD1</i>, <i>2</i>. <b><i>Results:</i></b> This retrospective study included 65 patients with ADPKD. Patients were divided into 3 groups: <i>PKD1</i>, <i>n</i> = 32; <i>PKD2</i>, <i>n</i> = 12; and non-<i>PKD1</i>, <i>2</i>, <i>n</i> = 21. The prevalence of mitral regurgitation (MR) was significantly higher in the <i>PKD1</i> group than in the <i>PKD2</i> and non-<i>PKD1</i>, <i>2</i> group (46.9% vs. 8.3% vs. 19.0%, respectively; <i>p</i> = 0.02). In contrast, no significant difference was found for other cardiac valve complications. <b><i>Conclusion:</i></b> This study found a significantly higher prevalence of MR in patients with the <i>PKD1</i> genotype than in those with the <i>PKD2</i> or non-<i>PKD1</i>, <i>2</i> genotypes. Physicians may need to perform echocardiography earlier and more frequently in patients with ADPKD and the <i>PKD1</i> genotype and to control fluid volume and blood pressure more strictly in these patients to prevent future cardiac events.
