Historical, Pharmacological, Clinical, and Regulatory Evolution of Hirudotherapy: An Evidence-Informed Traditional Narrative Review

Öz

Objectives: This traditional narrative review aimed to synthesize the historical development, pharmacological basis, contemporary clinical indications, safety concerns, contraindications, and regulatory framework of hirudotherapy. 

Methods: Literature was identified through targeted searches of PubMed, Scopus, CrossRef, Google Scholar, publisher databases, and official regulatory sources. The search focused on medicinal leech therapy, Hirudo medicinalis, hirudin, venous congestion, reconstructive surgery, microsurgery, knee osteoarthritis, contraindications, Aeromonas infection, and traditional and complementary medicine. Peer-reviewed reviews, systematic reviews, meta-analyses, randomized controlled trials, pharmacological studies, reconstructive surgery literature, historical sources, and official regulatory documents were prioritized. 

Results: Hirudotherapy has evolved from a traditional bloodletting practice into a mechanism-informed intervention with limited but clinically relevant modern indications. The strongest evidence-supported indication is the management of venous congestion after reconstructive microsurgery, replantation, and flap procedures. Symptomatic knee osteoarthritis appears promising but remains limited by methodological constraints and safety concerns. In contrast, broad claims involving cosmetic, metabolic, neurologic, reproductive, oncologic, or systemic diseases are insufficiently supported. Major risks include prolonged bleeding, anemia, allergic reactions, wound complications, and Aeromonas-related infection. 

Conclusion: Modern hirudotherapy should not be justified by historical continuity alone. It should be applied only within clearly defined indications, under medical supervision, with appropriate patient selection, infection-control measures, safety monitoring, and regulatory compliance.

Hirudoterapinin Tarihsel, Farmakolojik, Klinik ve Düzenleyici Gelişimi: Kanıta Dayalı Geleneksel Anlatı Derlemesi

Öz

güncel klinik kullanım alanlarını, güvenlilik sorunlarını, kontrendikasyonlarını ve düzenleyici çerçevesini değerlendirmektir. 

Yöntem: Literatür, PubMed, Scopus, CrossRef, Google Scholar, yayıncı veri tabanları ve resmî düzenleyici kaynaklarda yapılan hedeflenmiş taramalarla belirlenmiştir. Tarama; tıbbi sülük tedavisi, Hirudo medicinalis, hirudin, venöz konjesyon, rekonstrüktif cerrahi, mikrocerrahi, diz osteoartriti, kontrendikasyonlar, Aeromonas enfeksiyonu ve geleneksel ve tamamlayıcı tıp kavramları üzerine odaklanmıştır. Hakemli derlemeler, sistematik derlemeler, meta-analizler, randomize kontrollü çalışmalar, farmakolojik araştırmalar, rekonstrüktif cerrahi literatürü, tarihsel kaynaklar ve resmî düzenleyici belgeler öncelikli olarak değerlendirilmiştir. 

Bulgular: Hirudoterapi, tarihsel kan alma uygulamasından, günümüzde mekanizması daha iyi anlaşılmış ancak sınırlı klinik endikasyonlara sahip bir girişime dönüşmüştür. En güçlü kanıta dayalı kullanım alanı, rekonstrüktif mikrocerrahi, replantasyon ve flep cerrahisi sonrasında gelişen venöz konjesyonun yönetimidir. Semptomatik diz osteoartritinde umut verici bulgular bulunmakla birlikte, kanıtlar yöntemsel sınırlılıklar ve güvenlilik sorunları nedeniyle dikkatle yorumlanmalıdır. Kozmetik, metabolik, nörolojik, üreme sistemi, onkolojik veya sistemik hastalıklara yönelik geniş iddialar ise yeterli düzeyde desteklenmemektedir. Başlıca riskler uzamış kanama, anemi, alerjik reaksiyonlar, yara komplikasyonları ve Aeromonas ilişkili enfeksiyonlardır. 

Sonuç: Modern hirudoterapi yalnızca tarihsel süreklilik temelinde gerekçelendirilmemelidir. Uygulama, açıkça tanımlanmış endikasyonlarda, tıbbi gözetim altında, uygun hasta seçimi, enfeksiyon kontrol önlemleri, güvenlilik izlemi ve düzenleyici standartlara uyum ile gerçekleştirilmelidir.
