Prämenstruelles Syndrom (Investigativ)

Patienten-Zusammenfassung

Ist dies FDA-zugelassen fuer diese Anwendung?

Not FDA-cleared for premenstrual syndrome. FDA cleared medicinal leeches only for venous congestion in microsurgical reconstruction (K040187, 2004). Use here is Tier C investigational and only as an adjunct to standard pharmacotherapy.

Welche Evidenz existiert?

Tier C (investigational). Only small uncontrolled case series describe reductions in PMS symptom scores after sessions in the luteal phase. There are no controlled trials. Per ACOG 2018 guidance, PMS (and PMDD) is managed with lifestyle modification, SSRIs (continuous or luteal-phase dosing), combined hormonal contraception, and selected nutraceuticals (calcium, vitamin B6). Diagnosis requires confirmation by prospective symptom diary over at least 2 cycles. Mechanism is plausible only for somatic symptoms (mastalgia, bloating, headache); affective symptoms are less likely to respond to peripheral therapy.

Hauptrisiken

• Bleeding from bite sites for 6 to 24 hours after detachment, possibly additive to menstrual blood loss if cycle timing overlaps
• Bruising and tenderness over the lower abdomen or sacral area for 5 to 10 days
• Local skin infection or Aeromonas infection
• Allergic reaction to leech saliva
• Symptom worsening through pain at bite sites during the already symptomatic luteal phase
• Delay of SSRI, combined hormonal contraception, or lifestyle interventions, all of which have RCT evidence
• Missed diagnosis of PMDD requiring psychiatric stabilization
• Risk for venous thromboembolism if combined hormonal contraception is concurrent

Wer dies nicht in Betracht ziehen sollte

• Pregnant or breastfeeding patients
• Patients with heavy menstrual bleeding (additive blood loss risk)
• Patients on combined hormonal contraception with VTE risk factors
• Patients with PMDD requiring psychiatric stabilization
• Patients without prospective symptom diary confirming PMS diagnosis
• Patients on anticoagulants or with severe anemia

Was Sie Ihren Kliniker fragen sollten

• Has my PMS diagnosis been confirmed by prospective symptom diary over at least 2 cycles?
• Could I have PMDD or a comorbid mood disorder that needs psychiatric care?
• Have I trialed SSRIs (continuous or luteal-phase) or combined hormonal contraception?
• Have I trialed lifestyle modifications: exercise, caffeine reduction, calcium, vitamin B6?
• Where exactly will the leech be placed, and how does timing intersect with my cycle?
• What is the realistic expected benefit for somatic versus affective symptoms?
