Predictive value of procalcitonin for the therapeutic response of patients with uroseptic shock: a retrospective case-control study

OBJECTIVES

To evaluate the predictive value of procalcitonin (PCT) in assessing the therapeutic response of patients with uroseptic shock.

METHODS

This retrospective case-control study included 220 patients treated for uroseptic shock at Liyang People's Hospital between January 2018 and December 2023. Patients were classified into high-risk (HR) (n = 116) and low-risk (LR) (n = 104) groups based on their Sepsis-related Organ Failure Assessment (SOFA) scores after 14 days of treatment. Demographic, clinical, and laboratory data were collected, and PCT levels were measured using chemiluminescence. Correlation analysis and receiver operating characteristic (ROC) curve analysis were used to assess the predictive value of PCT.

RESULTS

The HR group had significantly higher PCT levels (25.33 ± 5.32 ng/mL) compared to the LR group (18.47 ± 2.88 ng/mL, P < 0.001). Elevated PCT levels were strongly correlated with poor therapeutic response (rho = -0.635, P < 0.001). Other markers, including hypertension (rho = -0.207, P = 0.002), CRP (rho = -0.224, P < 0.001), IL-6 (rho = -0.200, P = 0.003), TNF-α (rho = -0.151, P = 0.025), NEUT% (rho = -0.208, P = 0.002), GGT (rho = -0.160, P = 0.017), and BUN (rho = -0.198, P = 0.003), also showed significant negative correlations with treatment outcome. Conversely, PLT (rho = 0.156, P = 0.021) and the CD4+/CD8+ ratio (rho = 0.242, P < 0.001) were positively correlated with better treatment outcome. ROC analysis revealed an area under the curve (AUC) of 0.867 for PCT, indicating its strong predictive value.

CONCLUSIONS

PCT level is a robust predictor of therapeutic response in uroseptic shock patients and may be integrated into clinical protocols for sepsis management.

Development of a Predictive Nomogram for Sepsis in Patients with Urolithiasis-Related Obstructive Pyelonephritis

Background and Objectives: In patients with urolithiasis-related obstructive pyelonephritis (UROP), sepsis represents a critical and concerning complication that can substantially increase the mortality rate. This study aimed to identify the risk factors for sepsis in UROP patients and to develop a predictive nomogram model. Materials and Methods: We analyzed data from 148 patients who met the UROP criteria and were admitted to Chang Gung Memorial Hospital between 1 January 2016 and 31 December 2021. The primary outcome evaluated was the incidence of sepsis, as defined by the most recent Sepsis-3 guidelines. To identify potential risk factors for sepsis, we employed the Least Absolute Shrinkage and Selection Operator (LASSO) regression technique. Subsequently, we utilized multivariable logistic regression to construct the predictive model. Results: There was a total of 102 non-sepsis cases and 46 sepsis cases. Risk factors for sepsis in multivariable analysis were a history of diabetes mellitus (DM) (OR = 4.24, p = 0.007), shock index (SI) (×10-1) (OR = 1.55, p < 0.001), C-reactive protein (CRP) (mg/dL) (OR = 1.08, p = 0.005), and neutrophil to lymphocyte ratio (NLR) (×10) (OR = 1.58, p = 0.007). The nomogram exhibited an area under the receiver operating characteristic curve of 0.890 (95% CI 0.830-0.949). Conclusions: Our study demonstrated that patients with UROP who have DM, higher SI, higher NLR, and elevated CRP levels are significantly more likely to develop sepsis. These insights may aid in risk stratification, and it is imperative that clinicians promptly initiate treatment for those identified as high risk.

Impact of drainage catheter material, size, and anti-dislodgement mechanism on percutaneous nephrostomy exchange intervals: a systematic review protocol

Background: Percutaneous nephrostomy (PCN) is a commonly performed procedure by interventional radiology and urology to treat urinary obstruction. In this procedure, a catheter is percutaneously placed into the renal pelvis for urinary diversion or hemorrhagic cystitis. Material type, catheter size, and catheter shape (anti-dislodgement feature) ultimately contribute to the inherent traits of longevity in drainage catheter device. Reviewing the relative strengths or weaknesses of products in the existing clinical market may help clinicians critically appraise the devices they use with evidence-based findings from this review. Furthermore, a deeper understanding of the relative strengths and weaknesses of existing devices may help inform the next generation of drainage catheter devices to prolong the interval between exchanges without detriment to patient safety. Methods: The following electronic databases will be queried: PubMed, Web of Science, Cochrane from their inception to January 2023 to identify randomized controlled trials (RCTs) and cohort studies to investigate the differences that our interventions of catheter material, size, and dislodgement mechanism will have on the exchange interval (standard of care 90 days vs. 60 days vs. 45 days vs. 30 days). The primary outcomes will be the drainage catheter exchange frequency. Ethics and dissemination: We aim to share our findings through high-impact peer reviewed journals. As drainage catheters and minimally invasive interventional radiology procedures become more popular, it is important for healthcare providers taking case of these populations to understand which variables might optimize patient care and minimize emergent exchanges. Data will be made available to readers. Registration: PROSPERO ( CRD42023432788, 16 June 2023).
