Paroxysmal Nocturnal Hemoglobinuria (PNH)

What is Paroxysmal Nocturnal Hemoglobinuria?

Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired clonal blood disorder in which the complement system destroys red blood cells inside the blood vessels.^[1] It can cause hemolytic anemia, blood clots and bone marrow failure.^{[1, 2]} It can be life-threatening, but treatment has improved survival greatly. StatPearls reports that survival at 10 years has risen from about 50 percent to above 75 percent since drugs such as eculizumab arrived.^[2]

Common symptoms

The most common symptom is fatigue due to chronic anemia, which can reduce quality of life.^[3] Other symptoms include shortness of breath, dark urine that is classically most noticeable in the morning, and smooth muscle spasms such as abdominal pain.^{[1, 2]}

• Kidney problems in some people^[2]
• Blood clots, often in unusual places such as the veins of the abdomen or liver^[4]
• Low blood counts when the bone marrow fails to make enough cells^[1]

Causes and risk factors

PNH is caused by an acquired mutation in a blood stem cell, which leaves red blood cells without protective surface proteins and open to attack by complement.^{[1, 2]} It is not inherited from parents in the usual way. Standard teaching is that the mutation is in the PIGA gene on the X chromosome.^[2]

How it is diagnosed and treated conventionally

Hematologists diagnose PNH with blood tests, including flow cytometry for the missing cell surface proteins, a blood count and markers of red cell breakdown such as LDH.^{[1, 5]}

Complement inhibitors that block C5, eculizumab and ravulizumab, treat hemolysis effectively and sharply lower the risk of clots, but they do not treat bone marrow failure.^[5] Blood thinners are used with them when a clot has formed.^[4] Newer complement inhibitors are in development or in use for people whose hemolysis continues despite treatment.^{[3, 4]} Allogeneic bone marrow (stem cell) transplant is the only curative option and is used only in selected cases.^{[1, 5]}

Why Paroxysmal Nocturnal Hemoglobinuria calls for a whole-person approach

PNH is a blood disease first, and its core treatment belongs to a hematologist. Living with it also involves long-term fatigue, regular infusions and the stress of a condition with serious complications. Approved treatments sharply reduce hemolysis and clot risk but come with an infusion schedule that can become burdensome, and not every patient has complete disease control.^[3]

The factors below are areas where supportive care may add comfort. They do not treat the disease.

Fatigue and anemia

Fatigue is the most common symptom of PNH and can affect well-being and quality of life.^[3] Fatigue needs a medical review of blood counts and treatment first.

Clot risk

Thrombosis affects up to 40% of people with PNH, mainly in the veins, and may be the first sign of the disease.^[4] This is a reason to be careful with any herb or supplement that might change bleeding or clotting.

Infection risk with treatment

Eculizumab raises the risk of life-threatening infection, notably meningococcal infection, so vaccination and close monitoring are standard.^{[6, 7]}

Treatment burden, stress and sleep

Regular infusions and uncertainty about the condition can disturb sleep and mood.^[3] Acupuncture and ashwagandha have been studied for sleep and stress in other groups, as described below.

Acupuncture as supportive care in Paroxysmal Nocturnal Hemoglobinuria

What the research shows

No clinical trials of acupuncture for PNH were found in PubMed, so there is no evidence that it affects hemolysis, blood counts or clot risk. Acupuncture should never be used in place of, or to delay, treatment from a hematologist.

For fatigue, evidence comes from other conditions. A meta-analysis of 16 studies in chronic fatigue syndrome found that acupuncture gave better response rates than sham acupuncture, but the certainty was low, most studies were of low quality and the authors reached no firm conclusion.^[8] An overview of 51 systematic reviews in cancer survivors found acupuncture appeared helpful for fatigue and insomnia, while rating most of the reviews as low in quality.^[9] Neither group had PNH.

For sleep, a review of 24 trials of acupuncture in insomnia included a meta-analysis of 15 trials that found better sleep scores than drug treatment after about three weeks, with large differences between trials.^[10] A 2024 review in primary insomnia reported better sleep, less fatigue and fewer emotional symptoms, and noted weaknesses in trial methods.^[11] Neither group had PNH.

How acupuncture may work

For sleep, researchers propose effects on brain chemicals, inflammatory signals and the stress hormone axis, mostly from animal studies.^[11] These are proposed explanations. No study has shown that acupuncture changes complement activity or red cell survival.

What treatment involves

Treatment uses fine, sterile, single-use needles, usually left in place about 20 to 40 minutes. A short course of visits is followed by reassessment. We would begin only once your hematologist is managing PNH and knows about the care.

In prospective studies, about 9 in 100 patients had a minor reaction such as bleeding, pain or redness at a needle site, and serious events occurred in about 1 in 10,000 patients.^[12] Tell the practitioner first if you have a bleeding disorder or a low platelet count, take blood thinners, are pregnant, or have a pacemaker (relevant to electroacupuncture). Because complement-inhibitor treatment raises infection risk, tell us about any recent infection or fever.^[6]

Ayurvedic medicine as supportive care in Paroxysmal Nocturnal Hemoglobinuria

The Ayurvedic view

Ayurveda has no classical name for PNH. Practitioners may describe the combination of pale skin, weakness and dark urine as a disorder of blood (Rakta) and Pitta, the principle said to govern heat and transformation. These are traditional categories for choosing care, not biomedical diagnoses.

Therapies that may be used

Ayurvedic support is individualized and may include:

• Regular, nourishing meals and steady sleep hours intended to ease fatigue and stress
• Relaxation practices such as breathing exercises and gentle yoga
• Herbs chosen individually, only after review of your medicines and your hematologist's plan

Panchakarma, the traditional cleansing program, is not appropriate for people with PNH. It may add strain to people who are anemic, frail or acutely ill, and it is not appropriate during pregnancy. Do not use iron or other supplements on your own, and ask your hematologist before any.

What the research shows

No clinical trials of Ayurvedic treatment for PNH were found, and there is no evidence that it changes the disease.

Ashwagandha has been studied for stress and sleep in other adults. A meta-analysis of 12 trials found lower anxiety and stress scores than with placebo, though the certainty was low and results varied widely between trials.^[13] A meta-analysis of 5 trials found a small improvement in sleep, with limited long-term safety data.^[14] None of these trials were in PNH, and how ashwagandha interacts with PNH treatment has not been established.

Herbal medicine as supportive care in Paroxysmal Nocturnal Hemoglobinuria

Herbs and formulas that have been studied

No herb or formula has been studied in clinical trials of PNH. Chinese medicine traditionally uses blood-nourishing and kidney-supporting formulas for anemia and fatigue, but we found no trials of them in PNH. We would not use herbs aimed at the blood disease itself.

What the research shows

There is no research on herbs in PNH, and nothing we found tests herbs for fatigue or sleep in this condition. Any herb would be a traditional choice, not an evidence-based treatment for PNH.

Safety and herb-drug interactions

Herbs matter more in PNH than in many conditions, because clotting, bleeding, infection risk and the liver are all involved. Reviews describe interactions between herbs and warfarin, with bleeding reported for herbs including dang gui, dan shen, ginger, ginseng and Boswellia.^[15] Herb-drug interactions can have serious clinical consequences, and a review documents effects on ciclosporin and other medicines.^[16] This matters if you take blood thinners or immunosuppressants.

Herbal and dietary supplements account for about 20% of drug-induced liver injury in the United States, which is relevant because PNH can already involve the liver and kidneys.^[17] About one fifth of Ayurvedic medicines bought online contained detectable lead, mercury or arsenic.^[18] Herbs should come from tested sources and be prescribed individually. Tell us if you are pregnant or breastfeeding or have liver or kidney disease.

Translating traditional medicine into modern biological language

This is interpretation, not equivalence. Chinese medicine might describe the fatigue, pallor and dizziness of anemia as qi and blood deficiency, and Ayurveda might describe the picture as weakened blood tissue. Researchers describe it as complement-mediated destruction of red blood cells and chronic anemia.^{[1, 3]}

For fatigue and sleep, acupuncture research looks at stress-hormone signaling, brain chemistry and inflammatory signals.^[11] These ideas loosely parallel traditional language about restoring energy. They do not suggest that acupuncture or herbs affect complement or marrow function.

How this care fits with your medical care

Complementary care is a supplement to your hematologist's treatment, never a substitute. Do not stop or change complement inhibitors, blood thinners or other prescribed medicines, and keep every infusion and blood test. For a condition like this, we ask that you are under a physician's care for it and that your treating team knows you are receiving complementary care.

We do not diagnose or monitor PNH. Please bring your diagnosis, recent blood count and LDH results, a list of all medicines including blood thinners and complement inhibitors, any supplements, and your hematologist's contact details.

When to seek urgent medical care

PNH can cause dangerous complications, including clots and serious infection, and new symptoms need prompt assessment.^{[4, 6]}

• Fever, stiff neck, severe headache or confusion, especially while on a complement inhibitor, which can signal meningococcal infection
• Sudden leg swelling and pain, chest pain, or shortness of breath, which can signal a clot
• Severe belly pain, or yellowing of the skin or eyes
• Sudden dark or red urine with severe weakness or dizziness
• Sudden weakness on one side, trouble speaking or vision loss

If any of these occur, call 911 or go to the nearest emergency department.
