Aplastic Anemia

By SWA

Aplastic anemia is a rare, potentially serious condition where the body stops producing enough new blood cells. Here is detailed information about its symptoms, diagnostic tests, DNA-related aspects, related illnesses, treatment options, and references with links for further reading:

Symptoms

  1. Fatigue and Weakness: Due to a low red blood cell count (anemia).
  2. Shortness of Breath: Particularly during physical activity.
  3. Frequent or Prolonged Infections: A result of low white blood cell counts (neutropenia).
  4. Easy Bruising or Bleeding: Including nosebleeds and bleeding gums, due to low platelet counts (thrombocytopenia).
  5. Pale Skin: Due to anemia.
  6. Dizziness or Lightheadedness: From reduced oxygen transport.
  7. Prolonged Bleeding from Cuts: Due to a deficiency in platelets.

Tests

  1. Complete Blood Count (CBC): Measures levels of red cells, white cells, and platelets.
  2. Reticulocyte Count: Measures immature red blood cells to determine bone marrow activity.
  3. Bone Marrow Biopsy and Aspiration: Confirms the diagnosis by showing a decrease in marrow cellularity.
  4. Flow Cytometry: Identifies specific markers on cells to diagnose and differentiate aplastic anemia from other conditions.
  5. Liver Function Tests: To rule out hepatitis as a cause.
  6. Paroxysmal Nocturnal Hemoglobinuria (PNH) Test: To check for a related blood disorder.
  7. Viral Studies: To identify possible viral infections causing bone marrow failure.

DNA-Related Aspects

  • Inherited Forms: Some forms of aplastic anemia can be inherited, such as Fanconi anemia. Genetic testing can identify mutations in genes related to these inherited forms.
  • Genetic Mutations: Mutations in certain genes (e.g., TERC, TERT) can predispose individuals to aplastic anemia. Genetic testing can help in diagnosing these mutations.

Related Illnesses

  1. Myelodysplastic Syndromes (MDS): Can present similarly but involves abnormal bone marrow cells.
  2. Paroxysmal Nocturnal Hemoglobinuria (PNH): A condition that can coexist with aplastic anemia.
  3. Fanconi Anemia: A genetic disorder leading to bone marrow failure.
  4. Acute Myeloid Leukemia (AML): Can arise as a complication of aplastic anemia.
  5. Viral Hepatitis: Can sometimes lead to aplastic anemia.
  6. Autoimmune Disorders: Conditions like lupus can cause or be associated with aplastic anemia.

Treatment

  1. Immunosuppressive Therapy: Medications like antithymocyte globulin (ATG) and cyclosporine.
  2. Bone Marrow Transplant (Hematopoietic Stem Cell Transplant): Especially for younger patients with a suitable donor.
  3. Blood Transfusions: To manage anemia and thrombocytopenia.
  4. Growth Factors: Such as erythropoietin or G-CSF to stimulate blood cell production.
  5. Antibiotics and Antifungals: To prevent or treat infections.
  6. Androgens: Hormones like danazol that may stimulate blood cell production in some cases.

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

By SWA

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...

Dysferlin Protein: Key Roles, Genetic Locations

By SWA

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By SWA

Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...
