Усталость при рассеянном склерозе (Исследовательское дополнение)

Краткая информация для пациента

Есть ли FDA-допуск для этого показания?

Not FDA-cleared for multiple sclerosis fatigue. FDA cleared medicinal leeches only for venous congestion in microsurgical reconstruction (K040187, June 2004). Use here is Tier C investigational.

Какие доказательства существуют?

Tier C (investigational). No controlled trials. Evidence-based first-line management of MS fatigue is optimization of disease-modifying therapy, treatment of comorbid sleep disorders, depression, and thyroid disease, structured aerobic exercise, and (with mixed but real evidence) amantadine, modafinil, or methylphenidate. Cognitive behavioral therapy specifically for MS fatigue also has RCT support.

Основные риски

• Bleeding from each bite site for 6 to 10 hours after the leech detaches
• Iron-deficiency anemia from cumulative blood loss across multiple sessions
• Aeromonas hydrophila wound infection from leech gut bacteria (uncommon outside reconstructive surgery, but possible)
• Allergic reaction to leech saliva (rare; ranges from local itching to anaphylaxis)
• Permanent Y-shaped bite-mark scars or hyperpigmentation at attachment sites
• Local pain, bruising, swelling, or itching for 1 to 3 days after each session
• Worsening of MS-related dysautonomia (orthostatic symptoms) after a session that draws blood volume
• Uhthoff phenomenon (heat-induced symptom worsening) if the session room is warm

Кому не следует это рассматривать

• Patients in an active MS relapse (focus must be on the relapse, not adjunctive therapy)
• Patients who have not had MS-specific fatigue evaluated for treatable mimics: anemia, hypothyroidism, depression, sleep apnea
• Anyone on blood thinners such as warfarin, apixaban, rivaroxaban, dabigatran, heparin, or daily aspirin used for medical reasons
• People with hemophilia or any other inherited bleeding disorder
• Patients with severe anemia (hemoglobin under 10 g/dL)
• People with an active infection at the planned application site
• Patients who are pregnant or breastfeeding (relative contraindication; insufficient safety data)

О чём спросить врача

• Has my fatigue been worked up for treatable causes — anemia, low thyroid, sleep apnea, depression?
• Am I on optimal disease-modifying therapy for my MS subtype?
• Have I tried amantadine, modafinil, or methylphenidate?
• What CBT or graded exercise programs for MS fatigue are available?
• What is the published evidence base for leeches in MS fatigue specifically?
• Could blood loss from sessions worsen my fatigue rather than help it?

Когда срочно обратиться за медицинской помощью

• Bleeding from a bite site that soaks through more than one dressing per hour
• Bleeding that continues more than 24 hours after the leech detached
• Spreading redness, warmth, swelling, pus, or red streaks around any bite site
• Fever over 38.0 C / 100.4 F, chills, or feeling suddenly unwell after a session
• Hives, facial or tongue swelling, throat tightness, or any difficulty breathing
• Sudden weakness, dizziness, fast heart rate, or fainting (possible severe blood loss)
• New or worsening neurologic symptoms — vision change, weakness, numbness, balance loss, bladder problems (possible MS relapse)
• Severe orthostatic dizziness or fainting on standing
