POEMS Syndrome

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, skin changes) – POEMS syndrome is a rare autoimmune related blood disorder that damages your nerves and affects many other parts of the body.

POEMS syndrome can be misdiagnosed because the signs and symptoms mimic those of other disorders. POEMS syndrome progresses rapidly and may become life-threatening, so early diagnosis is important.

POEMS stands for these signs and symptoms:

  1. Polyneuropathy. Numbness, tingling and weakness in your legs — and over time, maybe in your hands — and difficulty breathing.
  2. Organomegaly. Enlarged spleen, liver or lymph nodes.
  3. Endocrinopathy. Abnormal hormone levels that can result in underactive thyroid (hypothyroidism), diabetes, sexual problems, fatigue, swelling in your limbs, and problems with metabolism and other essential functions.
  4. Monoclonal plasma-proliferative disorder. Abnormal bone marrow cells (plasma cells) that produce a protein (monoclonal protein) that can be found in the bloodstream.
  5. Skin changes. More color than normal on your skin, possibly thicker skin and increased facial or leg hair.

POEMS syndrome is a rare, mulitisystem disorder. POEMS stands for the disorder’s features, which may include Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal gammopathy, and Skin changes. Signs and symptoms may include progressive sensorimotor polyneuropathy; enlarged liver, spleen, and/or lymph nodes; a disorder of the endocrine glands (often with multiple abnormalities); a monoclonal plasma cell proliferative disorder; and darkening of the skin (hyperpigmentation). Various other symptoms may also occur and may vary among affected people. The underlying cause of the disorder is not well understood. POEMS syndrome is a chronic disorder, with a median survival time of 8-14 years. There is no standard treatment; management depends on the underlying plasma cell disorder and may include radiation therapy, chemotherapy, and/or hematopoietic cell transplantation.[1]

The cause of POEMS syndrome is not well understood. POEMS syndrome is a paraneoplastic disorder, which means that the signs and symptoms of the syndrome appear as a manifestation of the plasma cell disorder that the patient has (most patients are seen with osteosclerotic myeloma or monoclonal gammopathy of unknown significance); however, the mechanism by which this occurs is unknown. It is associated with a chronic overproduction of some substances known as pro-inflammatory cytokines (small molecules that act as messengers between cells to promote inflammation). These include interleukins (IL-1b, IL6) which are cytokines that help regulate immune responses, TNFα (Tumor Necrosis Factor alfa is a cytokine which is involved in the inflammatory process) and vascular endothelial growth factor (VEGF – a powerful vasodilator that may cause leaky blood vessels) which seem to be important in this disorder.[1][2]

Types of POEMS Syndrome

There is generally one main type of POEMS syndrome, but it can vary in severity and presentation from person to person. The key features mentioned above are common to all cases, but their extent and impact may differ.

POEMS syndrome can manifest in different ways, and there are various subtypes. The two primary types are:

  1. Typical POEMS syndrome: This is the most common form, characterized by the classic symptoms we mentioned earlier.
  2. Atypical or incomplete POEMS syndrome: In this subtype, not all the classic features are present, making diagnosis more challenging.

Causes of POEMS Syndrome

The exact cause of POEMS syndrome is not well understood. However, it is believed to be related to the overproduction of a specific type of blood cell in the bone marrow. This abnormal cell production leads to the symptoms and complications associated with POEMS syndrome.

Common Causes:

  1. Genetic predisposition: Some individuals may have a genetic predisposition that makes them more susceptible to developing POEMS syndrome.
  2. Abnormal immune response: An overactive immune system can produce the M-protein seen in POEMS syndrome.
  3. Viral infections: Certain viral infections may trigger the syndrome in susceptible individuals.
  4. Inflammatory conditions: Chronic inflammatory conditions can increase the risk of developing POEMS syndrome.

Symptoms of POEMS Syndrome

POEMS syndrome can have a wide range of symptoms, which can vary from person to person. Some of the most common symptoms include:

  1. Numbness and Tingling: Many people with POEMS syndrome experience numbness and tingling in their hands and feet due to nerve damage.
  2. Weakness: Muscle weakness can make it difficult to perform everyday activities.
  3. Swelling: Enlargement of organs like the liver and spleen can lead to abdominal swelling.
  4. Endocrine Issues: Hormonal imbalances may cause symptoms like excessive thirst, weight gain, or changes in menstrual cycles.
  5. Skin Changes: Skin changes can include darkening, thickening, or the development of red or purple spots.
  6. Vision Problems: In some cases, changes in vision may occur.
  7. Breathing Difficulties: Rarely, breathing problems may develop due to lung involvement.
  8. Bone Abnormalities: Bone fractures or lesions can occur.
  9. Fatigue: Many people with POEMS syndrome experience extreme fatigue.
  10. Swallowing Problems: Difficulty swallowing may arise in some cases.
  11. Gastrointestinal Symptoms: This can include diarrhea, constipation, or other digestive issues.
  12. Edema: Swelling in the legs and ankles can be a symptom.
  13. Weight Loss: Unexplained weight loss can occur.
  14. Impaired Mobility: Nerve and muscle problems can affect mobility.
  15. Joint Pain: Joint pain and stiffness may develop.
  16. Headaches: Some people with POEMS syndrome experience severe headaches.
  17. Chest Pain: Chest pain can be a rare symptom.
  18. Cognitive Changes: In some cases, cognitive function may be affected.
  19. Fever: Fever may accompany other symptoms.
  20. Sensory Changes: Changes in sensation, such as a loss of touch or temperature sensation, can occur.

Diagnostic Tests for POEMS Syndrome

Diagnosing POEMS syndrome can be challenging because it mimics many other conditions. Doctors use a combination of tests to confirm the diagnosis, including:

  1. Blood Tests: These can reveal abnormal protein levels.
  2. Nerve Conduction Studies: These measure nerve function.
  3. Electromyography (EMG): It helps assess muscle function.
  4. Bone Marrow Biopsy: To check for abnormal cells in the bone marrow.
  5. Imaging Studies: X-rays, CT scans, or MRI scans can reveal organ enlargement.
  6. Skin Biopsy: This can help identify skin abnormalities.
  7. Hormone Tests: To check for endocrine issues.
  8. Pulmonary Function Tests: For assessing lung function.
  9. Eye Exams: To detect vision problems.
  10. Gastrointestinal Tests: To evaluate digestive symptoms.
  11. Cognitive Assessments: For evaluating cognitive changes.
  12. Cardiac Tests: If chest pain or heart-related symptoms are present.

Treatment for POEMS Syndrome

Managing POEMS syndrome typically involves a multidisciplinary approach, and the choice of treatment depends on the severity of symptoms. Here are some common treatment options:

  1. Observation: In mild cases, doctors may monitor the condition without active treatment.
  2. Radiation Therapy: This can target specific areas of overactive blood vessel growth.
  3. Chemotherapy: Medications may be used to reduce the production of abnormal blood cells.
  4. Stem Cell Transplantation: In severe cases, a stem cell transplant may be considered to replace abnormal bone marrow cells with healthy ones.
  5. Corticosteroids: These anti-inflammatory drugs can help manage symptoms.
  6. Plasma Exchange: Removing and replacing the plasma in the blood can help reduce abnormal proteins.
  7. Pain Management: Medications and physical therapy may be used to alleviate pain and improve mobility.
  8. Hormone Replacement: For addressing endocrine issues.
  9. Supportive Care: Managing specific symptoms like breathing difficulties, skin changes, or digestive problems.
  10. Physical and Occupational Therapy: To improve strength and function.
  11. Psychological Support: Dealing with a rare condition like POEMS syndrome can be emotionally challenging, and counseling or support groups can be beneficial.
  12. Surgery: In some cases, surgery may be necessary to address organ enlargement or other complications.

Drugs Used in POEMS Syndrome Treatment

Several drugs may be prescribed to manage the symptoms and underlying causes of POEMS syndrome:

  1. Corticosteroids: These drugs reduce inflammation and can help control various symptoms.
  2. Chemotherapy Agents: Medications like melphalan and thalidomide can target abnormal cell production.
  3. Immunomodulatory Drugs: Lenalidomide and pomalidomide are examples that can modify the immune response.
  4. Radiation Sensitizers: Medications like bortezomib can enhance the effectiveness of radiation therapy.
  5. Pain Medications: Analgesics like opioids or non-steroidal anti-inflammatory drugs (NSAIDs) may be used for pain management.
  6. Hormone Replacement: If endocrine issues are present, hormone replacement therapy may be necessary.
  7. Plasma Exchange Agents: Medications that facilitate the process of plasma exchange.
  8. Supportive Medications: Medications for specific symptoms, such as anti-diarrheal drugs, antiemetics, or antipyretics.

In Conclusion

POEMS syndrome is a rare and complex condition that affects multiple systems in the body. While it can be challenging to diagnose and manage, a combination of diagnostic tests, treatment options, and supportive care can help individuals with POEMS syndrome lead fulfilling lives. If you or someone you know is experiencing symptoms suggestive of POEMS syndrome, it is essential to seek medical attention for a proper evaluation and diagnosis.
