Necesidades prioritarias de investigación
Multi-Center RCTs
Large, multi-center randomized controlled trials are needed for all major indications to achieve the statistical power required for guideline-level evidence.
Long-Term Follow-Up
Studies with 2+ years of follow-up are needed to establish durability of treatment effects and optimal maintenance protocols.
Cost-Effectiveness
Health economic analyses comparing leech therapy to standard interventions are essential for insurance coverage decisions and health policy integration.
Mechanism Studies
Detailed investigation of specific salivary compounds, their pharmacokinetics, and molecular pathways underlying therapeutic effects.
Optimal Protocols
Systematic dose-finding studies to determine optimal leech count, application frequency, treatment duration, and maintenance schedules.
Patient Selection
Biomarker and clinical predictor studies to identify patients most likely to respond to leech therapy, enabling personalized treatment.
