Renal infections in autosomal dominant polycystic kidney disease
Insights
Renal infections are common in autosomal dominant polycystic kidney disease (ADPKD), posing serious risks. Guidelines are provided for diagnosing and treating these challenging cyst infections.
Area of Science:
- Nephrology
- Infectious Diseases
Background:
- Renal infections are a frequent and serious complication in autosomal dominant polycystic kidney disease (ADPKD).
- These infections can lead to severe outcomes such as perinephric abscess, septicemia, and mortality.
- Predisposing factors include advanced age, female sex, and recent urinary tract instrumentation.
Purpose of the Study:
- To review recent studies on the characteristics of renal cysts in ADPKD.
- To discuss the relevance of cyst anatomy and function to treating renal infections.
- To establish guidelines for the diagnosis, antimicrobial therapy, and surgical management of ADPKD-related renal infections.
Main Methods:
- Review of recent scientific literature on ADPKD renal cyst characteristics and infections.
- Analysis of factors contributing to infection and challenges in treatment.
- Synthesis of information to formulate clinical guidelines.
Main Results:
- Autosomal dominant polycystic kidney disease (ADPKD) renal infections are often caused by gram-negative enteric organisms.
- Diagnosis can be challenging due to the absence of bacteriuria in some patients.
- Conventional antibiotic therapy may be ineffective in eradicating cyst infections despite in vitro organism sensitivity.
Conclusions:
- Understanding renal cyst characteristics is crucial for effective treatment of ADPKD infections.
- Guidelines are proposed for optimal diagnostic approaches, antimicrobial strategies, and surgical interventions.
- Improved management protocols are needed to address the complexities of treating renal infections in ADPKD patients.
Abstract:
Renal infection is a common occurrence in autosomal dominant polycystic kidney disease (ADPKD) and often leads to serious complications, including perinephric abscess, septicemia, and death. Important predisposing factors include age, female sex, and recent instrumentation of the urinary tract. Renal infections in ADPKD are most commonly caused by gram-negative enteric organisms. Diagnosis of these infections may be difficult since some patients do not have bacteriuria. Eradication of cyst infections with conventional antibiotic therapy can be difficult despite in vitro sensitivity of responsible organisms to the agents administered. We review recent studies of the anatomic and functional characteristics of renal cysts and discuss their possible relevance to the treatment of renal cyst infections. Finally, we set forth guidelines for the use of diagnostic studies, antimicrobial therapy, and surgical intervention for polycystic kidney infections.
