Lou Gehrig’s Disease, also known as Amyotrophic Lateral Sclerosis (ALS), is a rare but debilitating phenomenon that affects the body’s motor neuron cells.
This terminal illness causes gradual muscular degeneration, paralysis, and, ultimately, respiratory failure.
What is Hematology?
Hematology, the scientific study of blood, plays an essential role in diagnosing and managing Lou Gehrig’s Disease.
To better understand how Hematology is involved with Lou Gehrig’s Disease, it’s essential to have a fundamental understanding of the science. Hematology deals with blood cell formation and abnormalities in the coagulation process. Moreover, Hematology also involves the study of white blood cells, red blood cells, and platelets.
The Hematology of Lou Gehrig’s Disease
As ALS impacts the motor neurons in the spinal cord, it’s no surprise that the disease can lead to several hematological abnormalities.
One of the most common hematological complications of ALS is thrombocytosis, which is a high platelet count in the blood. This condition may occur due to the release of platelets from the spleen or increased platelet production by megakaryocytes. Furthermore, individuals with ALS also have a higher risk of developing venous thromboembolism (VTE).
The reason behind the higher incidence of VTE in ALS patients is that immobility due to muscle atrophy increases blood coagulability. As a result, the blood clot formation risk of patients with ALS is significantly higher than in the general population.
Therefore, it is important to manage this risk by using blood thinners such as Warfarin or Heparin.
Blood-Based Biomarkers for ALS Diagnosis
Currently, there is no definitive diagnostic test for ALS. Instead, physicians must rely on a combination of physical examination, laboratory tests, and medical history to diagnose the disease. Blood-based biomarkers can aid in the diagnostic process.
Biomarkers are any measurable biological molecules that can indicate a particular physiology, pathophysiology, or a specific disease. While there are no firmly established ALS-specific biomarkers, several potential biomarkers have shown promising results for ALS diagnostics and prognostic purposes via hematological measures.
Hematological Biomarkers for ALS
Iron and Ferritin: Research has shown that patients with ALS have a higher concentration of iron than healthy individuals. In addition, ALS patients have higher levels of ferritin, a protein that helps store iron.
Therefore, the measurement of these biomarkers can be beneficial in the early diagnosis of ALS and help in differentiating the disease from other neuromuscular conditions, which have lower concentrations of iron.
Thyroid hormone: Studies have found an association between ALS progression and thyroid hormone levels in patients. Furthermore, the initial diagnosis of ALS is often delayed due to overlapping symptomatology with thyroid disease.
Therefore, testing thyroid hormone levels via hematological measures could aid in the differential diagnosis of ALS, particularly in cases of delayed diagnosis.
Neutrophil-lymphocyte ratio (NLR): The NLR refers to the ratio of absolute neutrophil count to lymphocyte count. It is an inflammatory marker that can indicate tissue damage, inflammation, oxidative stress, and immune system status.
Research indicates that ALS patients have a higher NLR ratio compared to healthy individuals, indicating an association between inflammation and this neurodegenerative disease. Therefore, measuring NLR via hematological measures can aid in the early diagnosis and monitoring of ALS.
Treatment Options for ALS with Hematology
There is currently no cure for Lou Gehrig’s Disease. However, hematological measures can help in managing symptoms and improving the quality of life in ALS patients. Riluzole is the only FDA-approved medication for ALS.
This drug aims to combat glutamate excitotoxicity, which causes motor neuron degeneration. However, clinical trials have shown that hematological complications are frequent in patients taking Riluzole, including anemia, thrombocytopenia, and raised liver enzyme levels.
Therefore, hematological measures such as checking red and white blood cells and platelet counts are vital during Riluzole treatment to manage any potential complications.
Furthermore, hematological measures can help monitor the progression of the disease and assess the efficacy of treatment interventions.
Conclusion
Hematology plays an essential role in managing Lou Gehrig’s Disease. From blood-based biomarkers for early diagnosis to managing complications of treatment, hematological measures are crucial in managing this debilitating condition.
With further research, Hematology will continue to play an important part in enhancing our understanding of this disease and improving patient outcomes.
