Frequently Asked Questions
What are the key differences between acute and chronic inflammation in the pathophysiology of disease?
Acute inflammation is characterized by rapid onset, short duration, and the presence of neutrophils, aiming to eliminate the offending agent and initiate healing. Chronic inflammation persists over longer periods, involves mononuclear cells like macrophages and lymphocytes, and often leads to tissue destruction and fibrosis. The underlying mechanisms differ in cellular response, mediators involved, and tissue outcomes.
How does ischemia lead to cellular injury in pathophysiology?
Ischemia causes a reduction in blood flow, leading to decreased oxygen and nutrient delivery. This impairs ATP production, causing failure of ion pumps, cellular swelling, and accumulation of metabolic waste. Prolonged ischemia results in cell membrane damage, apoptosis, or necrosis, contributing to tissue injury and organ dysfunction.
What is the role of the complement system in immune-mediated tissue damage?
The complement system enhances immune responses by promoting inflammation, opsonization, and cell lysis. In immune-mediated tissue damage, inappropriate activation of complement can lead to excessive inflammation, recruitment of neutrophils, and destruction of host tissues, as seen in autoimmune diseases like systemic lupus erythematosus.
Describe the pathophysiological mechanisms underlying atherosclerosis.
Atherosclerosis involves endothelial injury, lipid accumulation, and inflammatory responses within arterial walls. LDL cholesterol infiltrates the intima, becomes oxidized, and triggers immune cell recruitment. Macrophages ingest lipids to form foam cells, leading to fatty streaks, plaque formation, and potential plaque rupture, which can cause ischemic events.
How do hormonal imbalances contribute to the pathophysiology of diabetes mellitus?
In diabetes mellitus, insulin deficiency (Type 1) or insulin resistance (Type 2) impairs glucose uptake by cells, leading to hyperglycemia. Chronic hyperglycemia damages blood vessels, nerves, and organs through mechanisms like glycation end-products and oxidative stress, resulting in complications such as neuropathy, nephropathy, and cardiovascular disease.
What are the common cellular adaptations in response to chronic stress, and how do they contribute to disease?
Cellular adaptations include hypertrophy, hyperplasia, atrophy, and metaplasia. While initially protective, these changes can lead to pathological states. For example, metaplasia may predispose to dysplasia and cancer, and hypertrophy can contribute to organ dysfunction, all of which play roles in disease progression.
