Hirudotherapy attenuates arthritic pain in patients with various chronic pain syndromes: A retrospective analysis
Research article published in Journal of integrative medicine (2020)
Abstract
OBJECTIVE: Osteoarthritis is a degenerative disease that affects synovial joints. Micro-injuries of articular structures initiate inflammatory processes, leading to persistent pain. Due to various risk factors, osteoarthritis is often diagnosed in multimorbid patients. This makes pain management one of the key challenges, with a consistent need for new therapeutic strategies. Hence, complementary and integrative methods such as hirudotherapy have become increasingly important, even though their mechanisms of action are not entirely understood. METHODS: We retrospectively analyzed the longitudinal effect of a single leech application on osteoarthritic joints in a heterogenic cohort of 24 cases with various chronic pain syndromes. We assessed articular pain intensity ratings and movability of the treated joint after one-time leeching for up to 12 months. We further investigated the effect of hirudotherapy on the systemic pain status and multimodal treatment strategies of the patients. RESULTS: There was a significant reduction in pain intensity ratings at the joint of leech application for up to 12 months after treatment. The improvements in pain intensities were independent of the form of osteoarthritis treated. In addition, we saw a considerable enhancement in local movability of the treated joint. Hirudotherapy did not seem to influence the systemic pain status as well as the previously established individualized multimodal treatment model of the patients. CONCLUSION: Leeching as an adjuvant therapy has a great potential especially in terms of safety and long-term outcome.

Summary
Osteoarthritis is a degenerative disease that affects synovial joints. Micro-injuries of articular structures initiate inflammatory processes, leading to persistent pain.
Why This Matters for Hirudotherapy
This retrospective analysis examined 24 cases of patients with various chronic pain syndromes who received a single leech application to osteoarthritic joints, with pain intensity and joint movability assessed for up to 12 months. The findings are directly relevant to hirudotherapy, reporting significant reductions in local articular pain and improvements in joint mobility that persisted for up to one year, while no changes were observed in systemic pain status or patients' established multimodal treatments. These results offer clinical evidence supporting the local analgesic potential of leeching as an adjuvant therapy for osteoarthritis. However, as a retrospective analysis of a small, heterogeneous cohort of 24 cases, the findings have limited generalizability and remain hypothesis-generating, and the mechanisms underlying the reported pain relief are not characterized.
