Diabetic Ketoacidosis ll: Pathophysiology

Diabetic Ketoacidosis ll: Pathophysiology

Diabetic ketoacidosis (DKA) is a metabolic emergency characterized by hyperglycemia, ketonemia, and metabolic acidosis. It results from severe insulin deficiency and an excess of counterregulatory hormones, leading to uncontrolled lipolysis, ketogenesis, and widespread electrolyte and fluid disturbances.Pathophysiology The central event in DKA is a profound loss of insulin action. Without insulin, glucose uptake in insulin-dependent tissues is impaired, while hepatic glucose production...

Antihypertensive Drugs: Potassium-Sparing Diuretics

Antihypertensive Drugs: Potassium-Sparing Diuretics

Liddle syndrome is a genetically inherited form of hypertension characterized by the overactivity of epithelial sodium channels in the nephron, the functional unit of the kidney. This heightened activity leads to increased sodium reabsorption and excessive excretion of potassium. To counteract this, potassium-sparing diuretics such as amiloride are used. They function by blocking these sodium channels, thereby reducing the influx of sodium into the epithelial cells and minimizing the loss of...

Diabetic Ketoacidosis l: Introduction

Diabetic Ketoacidosis l: Introduction

DefinitionDiabetic ketoacidosis (DKA) is an acute, life-threatening complication of diabetes mellitus, characterized by a triad of hyperglycemia (blood glucose >250 mg/dL), ketonemia or ketonuria, and metabolic acidosis (arterial pH <7.30 and serum bicarbonate <18 mEq/L). It results from insulin deficiency combined with elevated levels of counterregulatory hormones—glucagon, catecholamines, cortisol, and growth hormone—leading to increased lipolysis, hepatic ketone production, and...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Hyperthyroidism I: Introduction

Hyperthyroidism I: Introduction

Hyperthyroidism is a type of thyrotoxicosis characterized by the thyroid gland's overproduction of the thyroid hormones triiodothyronine (T3) and thyroxine (T4). This hormone excess increases the basal metabolic rate and enhances sensitivity to catecholamines.DiagnosisDiagnosis is based on clinical features and biochemical testing. It typically shows suppressed thyroid-stimulating hormone (TSH) levels below 0.4 mIU/L, with elevated free T3 and/or T4. Additional tests, including thyroid...

Summary

This summary is machine-generated.

Persistent hyperkalaemia in older adults is often due to hyporeninaemic hypoaldosteronism. Early recognition and management with diet and diuretics are key for this common condition.

Area of Science:

Nephrology
Endocrinology
Geriatrics

Background:

Persistent hyperkalaemia is common in the elderly.
Hyporeninaemic hypoaldosteronism is an under-recognized cause of hyperkalaemia in this population.
General practice often overlooks this endocrine disorder.

Observation:

This article emphasizes suspecting hyporeninaemic hypoaldosteronism in elderly patients presenting with persistent hyperkalaemia.
It provides a guide for investigating and managing this condition.

Findings:

Elderly patients with persistent hyperkalaemia may have hyporeninaemic hypoaldosteronism.
Diagnosis involves calculating the transtubular potassium concentration gradient and measuring serum aldosterone.
Management includes dietary potassium restriction and diuretic therapy (loop or thiazide).

Implications:

Increased awareness of hyporeninaemic hypoaldosteronism can lead to earlier diagnosis and treatment in elderly patients.
Proper management can prevent complications associated with persistent hyperkalaemia.
This condition requires a focused approach in geriatric care and general practice.
