Summary
Hyperlactataemia, a marker of poor prognosis, can stem from causes beyond cellular hypoxia. Factors like medications and cancer cell metabolism complicate its diagnosis, necessitating a broader differential approach.
Area of Science:
- Biochemistry
- Critical Care Medicine
- Pharmacology
Context:
- Hyperlactataemia is a critical indicator of poor prognosis in intensive care units, often associated with acute circulatory failure.
- While cellular hypoxia is a common cause, other factors can significantly influence blood lactate levels.
- Understanding these diverse causes is crucial for accurate diagnosis and patient management.
Purpose:
- To explore the multifaceted causes of hyperlactataemia beyond cellular hypoxia.
- To highlight the role of various factors, including medications and tumor metabolism, in elevated blood lactate.
- To emphasize the complexity of differential diagnosis for hyperlactataemia.
Summary:
- Blood lactate levels result from a dynamic balance between production and elimination, influenced by numerous factors.
- Medications such as propofol in anesthesiology and certain anti-retrovirals in HIV patients can elevate lactate.
- Tumor cells can also contribute to hyperlactataemia through anaerobic metabolism, complicating clinical interpretation.
Impact:
- This research underscores the need for a comprehensive differential diagnosis in cases of hyperlactataemia.
- Recognizing non-hypoxic causes can lead to more targeted and effective patient treatment strategies.
- Improved understanding of lactate regulation can enhance clinical decision-making in critical care and oncology settings.

Blood Pressure Imbalances and Circulatory Shock
Disorders affecting blood volume, vascular tone, or vascular function can disrupt vascular homeostasis, including conditions like hypertension, hemorrhage, and shock.
Blood Pressure: Hypertension and Hypotension
Normal blood pressure is 120/80 mm Hg. Elevated blood pressure is 120-129/under 80 mm Hg. Hypertension, warranting treatment at 130/80 mm Hg, is often asymptomatic and can lead to severe cardiovascular events, aneurysms, peripheral arterial disease, chronic renal disease, or cardiac...

Hemodialysis II: Procedure and Complications
DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...
Heart Failure VI: Adjunct Therapies
Additional therapies for treating patients with heart failure (HF) may include procedural interventions, supplemental oxygen, the management of sleep disorders, and nutritional therapy.Procedural InterventionsImplantable Cardioverter-Defibrillator: For patients at risk of life-threatening arrhythmias due to severe left ventricular dysfunction, an Implantable Cardioverter-Defibrillator (ICD) can detect and terminate these arrhythmias, preventing sudden cardiac death and improving survival rates.
Heart Failure Drugs: Inotropic Agents
Positive inotropic agents are commonly used as the first line of treatment for heart failure. One such agent is digoxin, derived from the genus Digitalis, which has been known for centuries but effectively utilized since 1785. However, these cardiac glycosides can have potentially toxic effects due to their mechanism of action, which involves inhibiting Na+/K+-ATPase and increasing contractility. Digoxin is absorbed orally and distributed in various tissues, including the CNS. It has a long...
Hormonal Regulation of Blood Pressure
Endocrinal or hormonal intervention in the cardiovascular system is predominantly exerted by the catecholamines - epinephrine and norepinephrine, as well as a slew of hormones that interact with renal function to modulate blood volume.
Epinephrine and Norepinephrine
The adrenal medulla releases epinephrine and norepinephrine, catecholamines that enhance and extend the sympathetic or "fight or flight" physiological response. These hormones escalate heart rate and the force of contraction while...

Ascites
DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...
