Step 1 - Aplastic anemia

The pathophysiology often involves an autoimmune attack on hematopoietic stem cells, where T-lymphocytes mistakenly target these cells, resulting in their destruction. This can be triggered by factors such as viral infections (e.g., hepatitis, parvovirus), exposure to toxins (e.g., benzene, certain medications), or inherited conditions (e.g., Fanconi anemia). The depletion of stem cells leads to insufficient production of blood cells, causing symptoms like fatigue, increased bleeding, and susceptibility to infections. In some cases, intrinsic factors affecting the stem cells themselves, such as genetic mutations, can also contribute to the condition. #USMLE #Step1 #Aplasticanemia #MedicalSchool #MedStudent
