The ASH Research Library provides in-depth reviews of significant peer-reviewed publications relevant to hirudotherapy. Each article is contextualized for clinical and translational relevance, with full citations and links to primary sources.

Evidence discipline

All articles are reviewed against primary sources. Preclinical research is clearly distinguished from clinical evidence. Regulatory context (FDA-cleared vs. investigational) is noted where applicable.

Research categories

Antimicrobial Resistance

AMPs, antibiotic synergy, and novel approaches to drug-resistant pathogens.

Drug Development

Bench-to-bedside translation of leech-derived compounds.

2 articles

Clinical Trials

Randomized controlled trials and systematic reviews of leech therapy outcomes.

2 articles

Safety & Infection Control

Aeromonas surveillance, prophylaxis protocols, and adverse event data.

Novel Leech Antimicrobial Peptides — Hirunipins

Antimicrobial Resistance

Kumar et al. (2025) — Advanced Science (Wiley)

First characterization of hirunipins — novel cysteine-rich antimicrobial peptides from Hirudo medicinalis saliva with activity against multidrug-resistant bacteria, biofilm disruption capability, and synergy with conventional antibiotics.

Leech Therapy for Knee Osteoarthritis — The Landmark RCT

Clinical Trials

Michalsen et al. (2003) — Annals of Internal Medicine

Landmark randomized controlled trial demonstrating that a single application of 4–6 leeches to the knee provided significant pain reduction (WOMAC −48%) lasting 3–6 months, with outcomes superior to topical diclofenac.

Leech-Assisted Flap Salvage — Systematic Review of 277 Cases

Clinical Trials

Whitaker et al. (2012) — Microsurgery

Systematic review of 277 cases across 67 publications (1966–2009) establishing the evidence base for the FDA-cleared indication. Overall flap salvage rate 60–83%, with Aeromonas infection reducing salvage from 88.3% to 37.4%.

434 Salivary Proteins — Integrated Proteomics of Hirudo medicinalis

Genomics & Proteomics

Liu et al. (2019) — Journal of Proteomics

Integrated proteomics and transcriptomics study identifying 434 full-length protein sequences from H. medicinalis salivary glands, including 44 confirmed bioactive proteins and 221 bioactive transcripts across 6 functional categories.
