Regenerative Peripheral Nerve Interface: Surgical Protocol for a Randomized Controlled Trial in Postamputation Pain

2.9K
Here, we describe the surgical procedure to perform Regenerative Peripheral Nerve Interface (RPNI) surgery for treating postamputation neuropathic pain in the context of an international, randomized controlled trial (RCT) (ClinicalTrials.gov, NCT05009394). The RCT compares RPNI with two other surgical techniques, namely, Targeted Muscle Reinnervation (TMR) and neuroma excision combined with intra-muscular...

Implantation of an Isoproterenol Mini-Pump to Induce Heart Failure in Mice

11.8K
The chronic administration of isoproterenol via an implanted osmotic pump has been used widely to mimic advanced heart failure in mice. Here, we describe detailed methods in surgical mini-pump implantation for the continuous isoproterenol administration over 3 weeks, as well as, echocardiographic assessment for the successful model...

Heart Failure II: Pathophysiology

761
Systolic Heart Failure and Compensatory MechanismsSystolic heart failure (also termed HFrEF, Heart Failure with Reduced Ejection Fraction) is the most prevalent type of heart filure. It results in a decreased volume of blood being pumped from the ventricle. The aortic arch and carotid sinuses have baroreceptors that detect reduced blood pressure, triggering the sympathetic nervous system (SNS) to release epinephrine and norepinephrine. Initially, this response aims to boost heart rate and...

Summary

Peritoneal ultrafiltration (PuF) for severe heart failure (HF) lacks evidence. The Peritoneal Dialysis for Heart Failure (PDHF) trial stopped early due to poor recruitment, highlighting challenges in researching this patient group.

Area of Science:

  • Nephrology
  • Cardiology
  • Clinical Trials

Background:

  • Peritoneal ultrafiltration (PuF) is used for severe heart failure (HF), but its efficacy is unproven.
  • Severe HF often coexists with chronic kidney disease (CKD), complicating treatment.
  • Lack of robust evidence necessitates trials to evaluate PuF in this population.

Purpose of the Study:

  • To investigate the benefit of PuF as an adjunct therapy for severe, diuretic-resistant HF with concurrent CKD.
  • To assess changes in functional capacity (6-minute walk test) and quality of life.

Main Methods:

  • A multicenter prospective randomized controlled trial (PDHF study) was designed.
  • Recruitment targeted 130 patients with NYHA class 3/4 HF and CKD stage 3/4.
  • Participants were randomized to conventional HF treatment or conventional treatment plus overnight PuF with Icodextrin.

Main Results:

  • The trial was halted early due to insufficient participant recruitment.
  • Only 10 out of 290 screened patients were recruited over two years.
  • Ineligibility was due to fluctuating eGFR, suboptimal HF treatment, frailty, and patient acuity.

Conclusions:

  • Researching severe HF patients with CKD is challenging.
  • Patient frailty, reluctance towards invasive procedures, and inter-service coordination issues hindered recruitment.
  • Lessons learned will inform future research in this complex patient cohort.
