ADPKD Research References

ADPKD research references, evidence anchors, and recent papers

This is the public evidence browser: searchable references, visible evidence tiers, and enough filtering to stop this page from feeling like a dump.

How to use this page

  • Start with tier: higher-tier evidence should shape your judgment first.
  • Then check study type: a guideline or randomized trial carries different weight than a retrospective cohort.
  • Then read limitations: that is where overclaiming usually falls apart.

PMID41881380: Association of Autosomal Dominant Polycystic Kidney Disease With Incident Aortic Dissection or Aneurysm

2026, Observational epidemiological cohort (n=2,568,283; 1,102 ADPKD; median f/u 1,043 days), Tier 2

Key claim: Multivariable-adjusted HR for AD/AA: 1.76 (95% CI 1.13–2.73). Aortic dissection: HR 2.53 (1.13–5.66). Aortic aneurysm: HR 1.56 (0.94–2.60). Risk more pronounced in BMI ≥25 vs <25. ADPKD cohort had lower atherosclerotic burden (DM 7.9%, CAD 2.6%, PAD 5.3%), suggesting ADPKD-specific vascular remodeling mechanism independent of atherosclerosis. Expands ADPKD extrarenal phenotype beyond intracranial aneurysm to aortic disease.

Limitations: ICD-10 code-based diagnosis (no genetic confirmation); potential residual confounding; possible detection bias; single-country population (Japan); unclear generalizability to other ancestry groups. Observational design limits mechanistic causal inference.

Limitations: Observational design with potential residual confounding; muscle strength/performance not captured; single-country tertiary-center cohort

Open source

PMID41771281: Autosomal dominant polycystic kidney disease (Lancet Review 2026)

2026, Comprehensive narrative review, Tier 1

Key claim: Comprehensive Lancet review summarizing current diagnostic and management approaches; reinforces tolvaptan as strong evidence-base disease-modifying treatment with early use support in high-risk groups; emphasizes risk-stratified management, comprehensive care pathway, and patient-centered shared decision-making. Coverage of genetics, diagnosis, prognosis, treatment (tolvaptan), complications (cyst infection, intracranial aneurysms, PLD management), and emerging therapies in clinical trials.

Limitations: Narrative review format (not systematic; expert-selected evidence); does not quantify new efficacy beyond prior RCTs; concentrates on integrating existing evidence into coherent care narrative

PMID41863404: Comparison of arteriovenous fistula outcomes in patients with and without autosomal dominant polycystic kidney disease: A retrospective study

2026, Retrospective observational cohort (ADPKD n=38 vs non-ADPKD n=38, age-matched, follow-up 24mo), Tier 2

Key claim: ADPKD patients undergoing first AVF creation showed comparable primary patency (63.2% vs 60.5%, p=0.81) and assisted primary patency (84.2% vs 73.7%, p=0.26) to non-ADPKD controls at 24 months despite significantly lower atherosclerotic comorbidities (diabetes 7.9% vs 52.6%, CAD 2.6% vs 31.6%, PAD 5.3% vs 23.7%). Suggests ADPKD-specific vascular remodeling (not atherosclerosis-driven) influences vascular access outcomes; distal AVF more common in ADPKD (73.7% vs 57.9%, p=0.147).

Limitations: Retrospective single-center design (n=38 per arm, modest sample). Short follow-up (24 months) may miss longer-term patency divergence. No mechanistic investigation of ADPKD vascular remodeling. Larger prospective studies needed. ADPKD cohort demographics/comorbidity patterns may differ from other centers.

PMID41864058: Development and validation of a predictive model for the lifetime risk of end-stage kidney disease in autosomal dominant polycystic kidney disease

2026, Retrospective cohort model derivation and internal validation (n=142 class 1 ADPKD adults, Mexico City 2012-2023), Tier 2

Key claim: Developed and internally validated an ADPKD risk-stratification model predicting ESKD by age 80 in class 1 ADPKD by combining baseline eGFR with exponential estimate of kidney volume growth. Validation showed excellent discrimination (C-index=0.94) and calibration (R²=0.858), comparable to Mayo Clinic Predictive Model (MCPM, C-index=0.95 for Cox). Model supports individualized lifetime ESKD risk prediction to guide targeted therapy initiation and resource allocation.

Limitations: Retrospective single-center cohort (Mexico City); internal validation only (external validation pending). TKV measured by ellipsoid method (not MRI-based Mayo classification imaging). Derivation/validation split limits true prospective external test performance. Applicability to non-Hispanic populations and other Mayo classes (2-5) unclear pending future external prospective validation.

TRIAL-FARBURSEN-2026: Farabursen Phase Ib trial: multiple-ascending dose study in autosomal dominant polycystic kidney disease

2026, Phase Ib clinical trial (dose-escalation, n=TBD, Regulus Therapeutics), Tier 3

Key claim: Farabursen (miR-17 targeting oligonucleotide, preferential kidney exposure) Phase Ib MAD trial showed promising efficacy and safety in reducing growth of cysts and kidney size, and delaying progression of ADPKD. First-in-class mechanism (miR-17 inhibition) with renal tropism. Completed Phase Ib; Phase II planned. Acquired by Novartis March 2026 ($1.7B, completed June 2025).

Limitations: Preprint/press release only (peer-reviewed publication not yet available). Phase Ib data not yet in peer-reviewed journal; trial details (n, dosing, efficacy metrics [htTKV %, eGFR slope] not yet specified). Mechanism of miR-17 targeting in ADPKD pathophysiology not yet validated in human disease. Phase II outcomes remain key confirmatory test. Novartis acquisition timeline and clinical development continuity should be monitored.

PMID41850000: Generation of a human-induced pluripotent stem cell line (NUMNi003-A) from a patient with autosomal dominant polycystic kidney disease harboring a PKD1 gene variant

2026, Resource/cell model generation study (human iPSC), Tier 4

Key claim: Successfully generated human-induced pluripotent stem cell (iPSC) line from ADPKD patient carrying PKD1 pathogenic variant (NUMNi003-A); provides cellular model resource for mechanistic studies and drug screening in human genetic ADPKD context. Verifies iPSC generation methodology and variant retention.

Limitations: Resource generation paper (no mechanistic findings or therapeutic efficacy). iPSC line validation for disease modeling still pending (differentiation to kidney cells, phenotypic characterization, drug-response profiling not reported in this resource paper). Cell line availability supports future research infrastructure.

Open source

PMID41826712: Genetic basis of the circle of Willis characteristics in the healthy and intracranial aneurysm population

2026, Population genetics/GWAS study (ancestry-stratified cohort n=~13,000+), Tier 3

Key claim: Genome-wide association identified PKD1L2 (closely related to PKD1) as genetic locus associated with circle of Willis characteristics and intracranial aneurysm (IA) risk. Finding strengthens PKD1-family gene involvement in intracranial vascular phenotypes; note: PKD1 itself is well-established IA risk gene in ADPKD context. PKD1L2 may represent parallel/related vascular developmental pathway.

Limitations: GWAS-derived signal (not mechanistically validated). PKD1L2 functional role in vascular development/IA risk unclear (association does not prove causation). IA screening/management remains clinical standard for ADPKD; PKD1L2 discovery may inform future IA prevention strategies but does not change current practice yet.

PMID41852146: Glycolytic alterations as biomarkers in polycystic kidney disease: A study using a PKD1 knockout model in NRK-52E rat kidney epithelial cells

2026, Preclinical mechanistic (cellular PKD1 knockout model), Tier 4

Key claim: PKD1 knockout in rat kidney epithelial cells (NRK-52E) induces metabolic alterations consistent with enhanced glycolytic metabolism; identifies glycolytic changes as potential biomarkers of PKD1-driven cystogenesis and as possible therapeutic targets. Metabolic profiling methodology developed.

Limitations: Preclinical cell-line study only (no animal models, no human data). NRK-52E cells are established cell line, not patient-derived. Mechanistic relevance to clinical ADPKD progression unclear. Biomarker identification does not imply therapeutic efficacy.

PMID42117913: HIF-Regulated Pannexin-1 Channel Drives Luminal ATP Accumulation in Kidney Cysts

2026, Preclinical mechanistic study (human tissue + murine/cell models), Tier 4

Key claim: HIF-1a promotes Pannexin-1 expression and ATP release into the cyst lumen, driving ATP-dependent cyst expansion; Pannexin-1 inhibitors reduced ATP release and cyst growth in vitro

Limitations: Preclinical human tissue and model-system study only; no patient efficacy or safety data; drug-repurposing implications remain speculative

Open source

PMID42184822: Identification of drug repurposing candidates for the treatment of polycystic kidney disease

2026, Preclinical drug-repurposing / target-identification study, Tier 4

Key claim: Birinapant, bardoxolone methyl, and salicylic acid were identified as repurposing candidates; salicylic acid showed the most promising mechanism profile in preclinical ADPKD models

Limitations: Preclinical only; no human efficacy or safety data; target engagement at clinically relevant concentrations does not establish clinical benefit

Open source

PMID41948116: Impact of visceral adipose tissue on eGFR slope in early ADPKD: evidence from a real-world cohort

2026, Real-world longitudinal observational cohort letter (n=39), Tier 2

Key claim: Higher MRI-measured visceral adipose tissue was independently associated with faster eGFR decline over about 31 months in early-stage ADPKD, including despite tolvaptan exposure in some participants.

Limitations: Small single-center observational cohort embedded in a letter format; residual confounding remains possible and the study does not prove that intentional fat loss improves renal outcomes or preserves tolvaptan benefit.

Open source

PMID41649706: Incidence and clinicopathological analysis of portal vein and inferior vena cava thrombosis in autopsy cases of autosomal dominant polycystic kidney disease

2026, Retrospective autopsy series (single center; 10 ADPKD cases over 37 years), Tier 2

Key claim: Autopsy review found portal vein/IVC thrombosis in 4 of 10 ADPKD cases, with larger kidney weight and compression-related venous stasis as plausible contributors, adding a niche advanced-disease complication signal.

Limitations: Tiny single-center autopsy series with substantial selection bias and no prospective incidence estimate; useful for clinician awareness in massively enlarged kidneys, not for broad screening or treatment recommendations.

PMID41876456: Investigating PKD2 deficiency-associated cardiomyopathies using hESC-cardiomyocytes and bioengineered 3D ventricular cardiac tissue strips

2026, Human cell/tissue model study (hESC-derived cardiomyocytes, 3D bioengineered ventricular tissue strips; PKD2-knockdown via shRNA), Tier 4

Key claim: PKD2 (polycystin-2) deficiency induces contractile dysfunction via endoplasmic reticulum (ER) stress (elevated BiP, CHOP, impaired Ca2+ handling) and reduced sarcoplasmic reticulum Ca2+-ATPase (SERCA2a) activity. Pharmacological rescue achieved partially via ER-stress alleviators (4-phenylbutyrate/tauroursodeoxycholic acid) or SERCA activators (CDN1163), demonstrating mechanistic targets for PKD2-associated cardiomyopathy intervention.

Limitations: Human cellular model only; no in-vivo animal validation. Partial rescue in vitro; translation to systemic cardiac benefit in ADPKD-PKD2 patients unknown. PKD2 mutations account for ~15% of ADPKD; findings may not generalize to PKD1-dominant ADPKD cardiomyopathies. No patient tissue/iPSC validation. Mechanism of PKD2 loss-of-function in cardiomyocytes vs. kidney epithelial cells differs; ADPKD cardiomyopathy prevalence and clinical significance warrant further investigation.

Key claim: XGBoost ML model (27-feature ensemble) predicted ADPKD dialysis progression with 98.3% accuracy and AUC 0.955 on held-out temporal test set; age 66+, anemia, CHF, AKI were top clinical risk factors

Limitations: Observational/administrative database design with temporal validation; model interpretability limited by ML ensemble black-box; single-country cohort may limit global generalizability

Open source

PMID42114268: Measuring the Impact of tolvaptan-induced polyuria on quality of life in patients with autosomal dominant polycystic kidney disease

2026, Prospective patient-reported outcome study, Tier 2

Key claim: Developed the TIPS questionnaire and showed tolvaptan-related polyuria meaningfully increases treatment burden and correlates with urinary volume.

Limitations: Small single-center study; symptom burden informs tolerability and shared decision-making but does not change tolvaptan efficacy ranking.

Open source

PMID42068455: Miniaturization of CRISPRa plasmids for efficient delivery into renal epithelial cells and Pkd1 transactivation

2026, In vitro gene-delivery / CRISPRa engineering study, Tier 4

Key claim: Mini-CRISPRa vectors improved delivery into mouse renal epithelial cells and drove endogenous Pkd1 upregulation in vitro, addressing a practical delivery bottleneck for activation-based gene therapy.

Limitations: Cell-culture only, no animal or human efficacy; improved transfection does not prove durable kidney correction or clinical safety.

Open source

2026, Human ex vivo model / platform study, Tier 4

Key claim: Human kidney tubuloids can model cAMP-driven cystogenesis and can be genetically modified with AAV, improving human-relevant PKD screening infrastructure.

Limitations: Platform study only; no treatment efficacy or clinical outcome data.

Open source

PMID41938343: Molecular genetic diagnosis of autosomal dominant polycystic kidney disease - A systematic review

2026, Systematic review of molecular diagnostic studies (20 studies, 2015-2025), Tier 2

Key claim: Targeted NGS panels showed the strongest overall diagnostic yield/cost-effectiveness for ADPKD molecular diagnosis, with MLPA and LR-PCR as useful adjuncts for complex PKD1 or copy-number variants. Strengthens structured genetic-testing workflow, not treatment efficacy.

Limitations: Heterogeneous included cohorts and lab methods; diagnostic yield depends on phenotype selection, sequencing workflow, and variant interpretation. Diagnostic-performance review does not show that broader testing improves renal outcomes by itself.

Open source

PMID42189409: Nationwide epidemiological survey of autosomal dominant polycystic kidney disease in Japan in 2022

2026, Nationwide epidemiological survey, Tier 2

Key claim: Updated Japanese prevalence estimates suggest 1 in 3,055 individuals with ADPKD not receiving KRT and 1 in 2,335 when KRT cases are included, indicating higher burden than previously recognized

Limitations: Survey response rate was 32.9% and KRT-coded cases may not be pure ADPKD; prevalence is an epidemiologic planning estimate, not a treatment or prognosis study

Open source

PMID41921047: Nutritional adequacy of ketogenic diets as a novel dietary intervention for people living with autosomal dominant polycystic kidney disease

2026, Diet-design and nutritional adequacy analysis, Tier 2

Key claim: An ADPKD-tailored ketogenic meal plan could meet macronutrient targets and most micronutrient targets, but iodine was low and iron/zinc may need supplementation in some groups

Limitations: Diet-planning study rather than efficacy trial; no eGFR, htTKV, symptom, adherence, or long-term safety outcomes; cost slightly higher than CKD reference meal plans

Open source

PMID41653026: Optimizing Next Generation Sequencing for Genetic Diagnosis in Autosomal Dominant Polycystic Kidney Disease

2026, Blinded diagnostic performance cohort (CRISP families), Tier 2

Key claim: Optimized exome sequencing detected 95.5% of known PKD1 pathogenic variants (100% with higher-depth ES), all PKD2 variants, and solved additional previously unsolved cases

Limitations: Reference-standard cohort design but not therapeutic efficacy evidence; performance depends on pipeline/capture depth and high-quality variant curation

Open source

PMID41911082: Overweight and Obesity are Associated with Lower Renal Blood Flow in Autosomal Dominant Polycystic Kidney Disease

2026, Cross-sectional observational cohort (early-stage ADPKD; n=134), Tier 2

Key claim: In non-diabetic adults with early-stage ADPKD and eGFR ≥60, overweight and obesity were independently associated with lower MRI-measured renal blood flow after adjustment for blood pressure, eGFR, and htTKV.

Limitations: Cross-sectional observational design cannot establish causality; BMI was adjusted for organ mass but still remains a crude adiposity surrogate, and the study does not show that weight loss or renal-blood-flow changes improve renal outcomes.

Open source

PMID41946363: Patient-derived kidney organoids recapitulate ADPKD and facilitate the identification of Rho pathway inhibitors as candidate therapeutics

2026, Patient-derived organoid platform + drug screen (adult renal organoids, single-cell transcriptomics, microfluidic perfusion), Tier 4

Key claim: Patient-derived adult renal organoids reproduced genotype-specific ADPKD cyst biology and identified Rho GTPase inhibition, including ML141, as a cyst-reducing candidate strategy. Strengthens human-model screening infrastructure and Rho/PCP target plausibility, not near-term efficacy.

Limitations: Organoid/drug-screen study only; no animal or human efficacy data. Candidate Rho inhibitors lack ADPKD clinical safety or kidney-delivery validation. Cyst reduction in organoids does not prove kidney-function benefit.

PMID41972228: Retroperitoneoscopic Nephrectomy at the Time of Kidney Transplantation for Autosomal Dominant Polycystic Kidney Disease: Safety, Efficacy, Feasibility, and Cosmetic Outcomes

2026, Comparative surgical cohort (retroperitoneoscopic vs open nephrectomy during kidney transplantation; n=19), Tier 2

Key claim: In a small single-center ADPKD transplant cohort, simultaneous retroperitoneoscopic nephrectomy appeared safe and less invasive than open nephrectomy, with similar operative time/blood loss and substantially less postoperative abdominal-wall muscle atrophy.

Limitations: Small non-randomized single-center series (RN n=11, ON n=8) with technique-specific expertise and early postoperative focus; useful for specialized transplant planning but not a broad management-changing result.

PMID41843812: Reversible cystogenesis in juvenile primate ADPKD models: evidence from PKD1 heterozygous monkeys

2026, Longitudinal primate model study (serial ultrasonography birth to age 5, cynomolgus/PKD1-het), Tier 3

Key claim: PKD1 heterozygous cynomolgus monkeys develop progressive cysts from birth matching human childhood ADPKD trajectory. Remarkably, subset of smaller cysts regressed spontaneously over time, challenging model of relentless progression. PKD1-mosaic monkeys showed similar plasticity. Biallelic PKD1-null monkeys developed severe cystic disease resembling advanced ADPKD. Findings suggest early cystogenesis represents therapeutic window where cyst regression may be promoted; raises mechanistic questions about plasticity of early cysts.

Limitations: Preclinical primate model (not human). Spontaneous regression observed in heterozygous setting (translational relevance to adult humans unknown). Serial ultrasonography methodology (not histologic confirmation). Biallelic animals represent severe phenotype not typical of human ADPKD. Monkey lifespan/disease kinetics differ from humans. Potential therapeutic implications require clinical validation.

PMID41897382: Role of Mediterranean Diet Adherence on Endothelial Dysfunction in Autosomal Dominant Polycystic Kidney Disease Patients

2026, Cross-sectional observational cohort (CKD G2-G4 ADPKD; n=63), Tier 2

Key claim: Higher Mediterranean-diet adherence in adults with ADPKD was associated with higher nitric oxide and lower endothelin-1 levels, suggesting more favorable endothelial-function profile as a supportive-care signal.

Limitations: Cross-sectional biomarker study with no htTKV, eGFR-slope, or clinical-event endpoint; small single-country cohort and potential dietary confounding mean this supports general diet-quality counseling, not disease-modifying claims.

PMID40810452: Typical and atypical ADPKD: predicted pathogenic genetic variants and population frequencies

2026, Computational population-genetics study, Tier 2

Key claim: Predicted pathogenic variants in typical ADPKD genes (PKD1/PKD2) present in ~1 in 314 people (PKD1: 1 in 417; PKD2: 1 in 916); atypical ADPKD genes (GANAB/ALG9/DNAJB11/ALG5/IFT140/NEK8) present in ~1 in 283 people. Pathogenic variants more common for atypical than typical ADPKD, particularly ALG9/DNAJB11. NEK8 monoallelic pathogenic-kinase-domain variants not found in gnomAD v.4.1.

Limitations: Computational inference from gnomAD cohort variants and ClinVar-annotated assessments; does not measure clinical penetrance/expressivity or verify all 'pathogenic' predictions in independent cohorts; may overestimate true disease prevalence if penetrance <100%

PMID42209684: Urinary biomarkers of tubular injury and inflammation in ADPKD patients under tolvaptan therapy

2026, Single-center cross-sectional biomarker study in tolvaptan-treated adults, Tier 2

Key claim: Urinary beta2-microglobulin was associated with faster eGFR decline and greater structural severity, while MCP-1, NGAL, and KIM-1 had limited adjusted prognostic utility

Limitations: Single-center cross-sectional study in tolvaptan-treated adults; no causal inference or treatment-effect data; biomarker associations need longitudinal validation

PMID42027549: Validation of Combining Total Kidney Volume and Kidney Failure Risk Equation in Autosomal Dominant Polycystic Kidney Disease

2026, Retrospective observational prognostic validation study, Tier 2

Key claim: In adults with ADPKD and baseline eGFR <60 mL/min/1.73 m², adding the Kidney Failure Risk Equation (KFRE) to Mayo Imaging Classification / TKV-based risk assessment improved prediction of kidney replacement therapy initiation or 40% eGFR decline versus imaging classification alone, strengthening combined risk-stratification use rather than changing treatment efficacy rankings.

Limitations: Now PubMed-indexed, which strengthens normalization and abstract-level verification, but this remains a retrospective cohort and does not prove outcome improvement from acting on the combined model. Predictive-performance gains were strongest in the eGFR <60 subgroup, and calibration/sample-detail interpretation still needs full-text review.

PMID41643210: Vascular transcriptional and metabolic changes precede progressive intrarenal microvascular rarefaction in ADPKD

2026, Longitudinal translational study (mouse + human cohorts, n=10–32 human validation), Tier 2

Key claim: Intrarenal microvascular rarefaction develops early (1–6 mo in Pkd1RC/RC model); preceded by vascular transcriptional dysregulation (110–201 DEGs at 1/6/12 mo). Plasma GABA, homocysteine (Hcy), asymmetric dimethylarginine (ADMA) elevated in ADPKD humans, correlate with TKV and renal blood flow decline; suggest endothelial dysfunction/metabolic dysregulation as early drivers.

Limitations: Mouse model (Pkd1RC/RC) is slowly progressive; human biomarker cohorts small (n=10–32); biomarker validation does not prove therapeutic targeting efficacy; causal pathway requires intervention studies.
