Bone marrow serves as the body’s blood cell production center, generating red blood cells, white blood cells, and platelets essential for oxygen transport, immune function, and blood clotting. When this system malfunctions, various health complications can arise, affecting energy levels, infection resistance, and overall well-being.

What Is Myelodysplastic Syndrome?

Myelodysplastic syndrome represents a group of disorders where the bone marrow fails to produce adequate healthy blood cells. Instead of functioning normally, the marrow creates abnormal or immature cells that cannot perform their intended roles effectively. These defective cells may die prematurely in the bone marrow or shortly after entering the bloodstream, resulting in low blood cell counts. The condition primarily affects older adults, with most cases diagnosed in individuals over 65 years of age. While the exact cause remains unclear in many cases, certain risk factors include previous chemotherapy or radiation therapy, exposure to specific chemicals like benzene, and genetic predispositions. The disorder progresses at varying rates, and in some instances, it may develop into acute myeloid leukemia, though this transformation does not occur in all patients.

Signs and Symptoms of MDS

Many individuals with myelodysplastic syndrome experience no symptoms in the early stages, with the condition often discovered during routine blood tests. As the disorder progresses, symptoms typically relate to the specific types of blood cells affected. Anemia, resulting from low red blood cell counts, commonly causes persistent fatigue, weakness, shortness of breath during normal activities, pale skin, and dizziness. When white blood cell counts drop, the immune system weakens, leading to frequent or recurring infections and slower healing from minor injuries. Low platelet counts increase bleeding tendencies, manifesting as easy bruising, small red spots under the skin called petechiae, prolonged bleeding from minor cuts, and frequent nosebleeds or bleeding gums. Some individuals may also experience unexplained weight loss, fever without infection, or bone pain. These symptoms develop gradually and may initially seem mild, which often delays diagnosis until blood work reveals abnormalities.

Myelodysplastic Syndrome Treatment Options

Treatment approaches depend on several factors, including the specific subtype of the disorder, the severity of symptoms, blood cell count levels, age, and overall health status. For lower-risk cases with mild symptoms, doctors may recommend watchful waiting with regular monitoring through blood tests and physical examinations. Supportive care forms a cornerstone of management and includes blood transfusions to address anemia and low platelet counts, growth factor injections to stimulate blood cell production, and antibiotics to treat or prevent infections. Medications targeting the disease process include hypomethylating agents like azacitidine and decitabine, which can improve blood cell counts and delay progression. Immunosuppressive therapy may benefit certain patients, particularly younger individuals with specific genetic markers. Lenalidomide, another medication, shows effectiveness in cases associated with particular chromosomal abnormalities. For higher-risk patients or those whose condition progresses toward leukemia, intensive chemotherapy similar to treatments used for acute myeloid leukemia may be necessary. Stem cell transplantation, also known as bone marrow transplantation, represents the only potentially curative treatment option. This procedure involves replacing diseased bone marrow with healthy stem cells from a compatible donor. However, it carries significant risks and is typically reserved for younger, healthier patients who can tolerate the intensive treatment process.

MDS Bone Marrow Disorder: Diagnosis and Monitoring

Diagnosing myelodysplastic syndrome requires comprehensive evaluation beginning with complete blood counts to assess levels of red blood cells, white blood cells, and platelets. Peripheral blood smears allow laboratory specialists to examine cell appearance and identify abnormalities. Bone marrow aspiration and biopsy provide definitive diagnosis by extracting samples for microscopic examination, revealing the percentage of abnormal cells and specific characteristics. Cytogenetic testing analyzes chromosomes within bone marrow cells to identify genetic changes that help classify the disorder and predict prognosis. Flow cytometry and molecular testing offer additional insights into cell characteristics and genetic mutations. These diagnostic tools help physicians determine the specific subtype and risk category, which guides treatment decisions. Regular monitoring remains essential throughout the disease course, as blood counts and symptoms can change over time, requiring treatment adjustments.

Living with a Bone Marrow Disorder

Managing life with myelodysplastic syndrome involves adapting to physical limitations while maintaining quality of life. Fatigue management becomes crucial, requiring individuals to balance activity with adequate rest, prioritize essential tasks, and accept assistance when needed. Infection prevention takes on heightened importance, including practicing meticulous hand hygiene, avoiding crowds during flu season, staying current with vaccinations as recommended by healthcare providers, and promptly reporting fever or signs of infection. Nutrition plays a supportive role, with emphasis on maintaining adequate protein intake, staying hydrated, and addressing specific dietary needs if treatment affects appetite or digestion. Emotional and psychological support proves equally important, as chronic illness impacts mental health. Connecting with support groups, seeking counseling when needed, and maintaining open communication with healthcare teams and loved ones can help individuals navigate the challenges of living with a bone marrow disorder.

When to Seek Medical Attention

Certain warning signs warrant immediate medical evaluation. Persistent fatigue that interferes with daily activities and does not improve with rest should prompt consultation with a healthcare provider. Unexplained bruising, particularly if it appears without injury or increases in frequency, requires investigation. Recurring infections, especially if they occur more frequently than usual or take longer to resolve, may indicate compromised immune function. Any unusual bleeding, including prolonged bleeding from minor cuts, frequent nosebleeds, or blood in urine or stool, needs prompt attention. Shortness of breath during routine activities that previously caused no difficulty may signal worsening anemia. Early evaluation allows for timely diagnosis and intervention, potentially improving outcomes and quality of life.
