What is POEMS Syndrome: Hematologic Diagnosis and Treatment?

POEMS is an acronym describing the major features: Polyneuropathy, Organomegaly, Endocrinopathy, Monoclonal protein, and Skin changes.

Driven by an underlying clonal plasma cell population producing high VEGF (vascular endothelial growth factor) levels.

Sclerotic bone lesions are characteristic and differ from lytic lesions of multiple myeloma.

Castleman disease coexists in approximately 15 percent of cases and influences treatment.

Treatment is directed at the underlying plasma cell clone, similar to multiple myeloma protocols.

Symptoms

Progressive symmetric distal polyneuropathy with weakness and sensory loss in feet and hands.
Hepatosplenomegaly, lymphadenopathy on imaging or examination.
Endocrine abnormalities: hypogonadism, hypothyroidism, hyperprolactinemia, adrenal insufficiency, diabetes.
Skin changes: hyperpigmentation, hypertrichosis, hemangiomas, plethora, white nails.
Edema, ascites, pleural effusions due to capillary leak from elevated VEGF.

Risk Factors

Underlying plasma cell dyscrasia with lambda light chain restriction in 95 percent of cases.
Coexisting Castleman disease modifies treatment approach.
Sclerotic bone lesions predict POEMS rather than typical myeloma.
Severe autonomic dysfunction increases treatment toxicity risk.
Advanced peripheral neuropathy may not fully recover despite hematologic response.

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Progressive weakness or numbness in feet or hands worsening over weeks.
  • Erectile dysfunction, amenorrhea, or new-onset diabetes.
  • Significant edema, ascites, or unexplained weight gain.
  • New skin changes: dark hyperpigmentation, hair growth, vascular lesions.
  • Persistent fatigue with thyroid or endocrine symptoms.

Treatment Methods

01
Limited disease (one to two bone lesions): localized radiotherapy 40 to 50 Gy can be curative.
02
Disseminated disease: high-dose melphalan with autologous stem cell transplant in eligible patients.
03
Non-transplant candidates: lenalidomide-dexamethasone or bortezomib-based regimens.
04
VEGF-targeted therapy (bevacizumab) explored in selected refractory cases.
05
Supportive care: thyroid replacement, testosterone, physical therapy for neuropathy rehabilitation.

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
