Abstract
Tuberous sclerosis complex (TSC) is an autosomal dominant disorder characterized by the presence of proliferative lesions throughout the body. Management of TSC is challenging because patients have a multifaceted systemic illness with prominent neurological and developmental impact as well as potentially severe kidney, heart and lung phenotypes; however, every organ system can be involved. Adequate care for patients with TSC requires a coordinated effort involving a multidisciplinary team of clinicians and support staff. This clinical practice recommendation was developed by nephrologists, urologists, paediatric radiologists, interventional radiologists, geneticists, pathologists, and patient and family group representatives, with a focus on TSC-associated kidney manifestations. Careful monitoring of kidney function and assessment of kidney structural lesions by imaging enable early interventions that can preserve kidney function through targeted approaches. Here, we summarize the current evidence and present recommendations for the multidisciplinary management of kidney involvement in TSC.

Standardized 4-point scoring scale of [ 18F]-FDG PET/CT imaging helps in the diagnosis of renal and hepatic cyst infections in patients with autosomal dominant polycystic kidney disease: a validation cohort. Clin Kidney J 2023; 16:2542-2548. [PMID: 38046039 PMCID: PMC10689132 DOI: 10.1093/ckj/sfad159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Indexed: 12/05/2023] Open
Abstract
Background Autosomal dominant polycystic kidney disease (ADPKD) is prone to multiple complications, including cyst infection (CyI). 2-Deoxy-2-[18F]fluoro-d-glucose positron emission tomography/computed tomography ([18F]-FDG PET/CT) imaging has proved useful in the diagnosis of renal and hepatic CyI. A 4-point scale comparing the uptake of [18F]-FDG in the suspected infected cyst versus the hepatic physiological background has been recently proposed. We performed an independent validation of this semi-quantitative scoring system. Methods All ADPKD patients hospitalized between January 2009 and November 2019 who underwent an [18F]-FDG PET/CT for suspected CyI were retrospectively identified using computer-based databases. Medical files were reviewed. CyI was conventionally defined by the combination of fever (≥38°C), abdominal pain, increased plasma C-reactive protein levels (≥70 mg/L), absence of any other cause of inflammation and favourable outcome after ≥21 days of antibiotics. [18F]-FDG uptake of the suspected CyI was evaluated using a 4-point scale comparing the uptake of [18F]-FDG around the infected cysts with the uptake in the hepatic parenchyma. Statistics were performed using SAS version 9.4. Results Fifty-one [18F]-FDG PET/CT scans in 51 patients were included, of which 11 were cases of CyI. The agreement between the 4-point scale and the gold-standard criteria of CyI was significant [odds ratio of 6.03 for CyI in case of a score ≥3 (P = .014)]. The corresponding sensitivity, specificity, and positive and negative predictive values of [18F]-FDG PET/CT using the 4-point scale were 64% [Clopper-Pearson 95% confidence interval (CI) 30%-89%], 78% (95% CI 62%-89%), 44% (95% CI 20%-70%) and 89% (95% CI 73%-97%), respectively. Conclusions Our independent validation cohort confirms the use of a semi-quantitative 4-point scoring system of [18F]-FDG PET/CT imaging in the diagnosis of CyI in patients with ADPKD. Considering its performance metrics with high specificity and negative predictive value, the scoring system is particularly useful to distinguish other causes of clinical inflammation than CyI and as such avoid unnecessarily long antibiotic treatment.

Abstract
Patients with autosomal dominant polycystic kidney disease benefit from specialized care over their lifetimes, starting with diagnosis of the condition with ongoing discussion of both the renal course and extra-renal issues. Both renal and extra-renal issues may continue to cause major morbidity even after successful kidney transplant or initiation of RRT, and extra-renal disease aspects should always be considered as part of routine management. In this review, we will focus on updates in pain/depression screening, cardiac manifestations, liver and pancreatic cysts, kidney stone management, and genetic counseling. In some instances, we have shared our current clinical practice rather than an evidence-based guideline. We anticipate more standardization of care after the release of the Kidney Disease Improving Global Outcomes guidelines for management in autosomal dominant polycystic kidney disease later this year.

Abstract
OBJECTIVE To determine the impact of antibiotic therapy (ATBT) on outcomes of renal cyst infection (CyI) in patients with polycystic kidney disease. PATIENTS AND METHODS We undertook a single-center retrospective study of CyI in autosomal dominant polycystic kidney disease (January 1, 2000, through December 31, 2018). Cyst infections were classified as definite (microbiologically proven), probable (radiologic signs), or possible (clinical or biologic signs only). We studied the determinants of ATBT failure (persistence of infection beyond 72 hours of microbiologically adequate initial ATBT, with requirement for ATBT change, cyst drainage, or nephrectomy) and recurrences (>14 days after the end of ATBT). RESULTS Among 90 patients, 139 CyIs (11 definite, 74 probable, 54 possible) were compiled. Cultures were positive in 106 of 139 (76%) episodes, with Escherichia coli found in 89 of 106 (84%). Treatment failures and recurrences within 1 year of follow-up were more frequent in definite/probable CyI (20/85 [34%] and 16/85 [19%]) than in possible CyI (2/54 [4%] and 4/54 [7%]; P<.01 and P=.08, respectively). Male sex (odds ratio [OR], 7.79; 95% CI, 1.72 to 46.68; P<.01), peak C-reactive protein level above 250 mg/L (OR, 7.29; 95% CI, 1.78 to 35.74; P<.01; to convert C-reactive protein values to nmol/L, multiply by 9.524), and cyst wall thickening (OR, 7.70; 95% CI, 1.77 to 43.47; P=.01) but not the modalities of initial ATBT were independently associated with higher risk of failure. In a Cox proportional hazards model, kidney transplant recipients exhibited higher risk of recurrence (hazard ratio, 3.76; 95% CI, 1.06 to 13.37; P=.04), whereas a total duration of ATBT of 28 days or longer was protective (hazard ratio, 0.02; 95% CI, 0.00 to 0.16; P<.001), with an inverse correlation between duration and recurrence (81% for treatment <21 days, 47% for 21 to 27 days, 2% for ≥28 days; P<.0001). CONCLUSION Initial first-line ATBT had no significant effect on renal CyI treatment failure. Treatment duration of 28 days and longer reduced recurrences.
