D Sickle cell anemia Sickle Cell Anemia patients who no longer have a functional spleen should receive the Meningococcal vaccine. Autosplenectomy greatly increases the risk of serious infection from encapsulated organism, such as N. meningitides, Strep pneumoniae, & H. influenzae.
What finding is commonly seen with primary adrenal insufficiency but not secondary adrenal insufficiency? A Fever B Hypoglycemia C Hyponatremia D Skin hyperpigmentation
D Skin hyperpigmentation Hypothalamus secretes CRH, which activates the Anterior Pituitary to release ACTH, which then stimulates the Adrenal Cortex to produce & release Cortisol. Primary Adrenal Insufficiency causes decreased Cortisol release from adrenal cortex, but the HPA axis is intact. Therefore, decreased Cortisol release causes increased ACTH levels, causing melanocyte stimulation and hyperpigmentation.
