The acute attack of porphyria
Summary
Acute neurological crises in porphyrias like variegate porphyria can be managed effectively with prompt treatment, minimizing mortality. This review outlines key symptoms and therapeutic strategies, including those targeting the heme pathway.
Area of Science:
- Biochemistry
- Genetics
- Neurology
Background:
- Acute neurological crises are the most severe complication of specific porphyria types.
- These include variegate porphyria, acute intermittent porphyria, and hereditary coproporphyria.
- Effective management can significantly reduce mortality rates.
Purpose of the Study:
- To outline the major symptoms and signs of acute porphyric attacks.
- To discuss the appropriate therapeutic interventions for symptom relief.
- To mention treatments that can modulate the heme biosynthetic pathway.
Main Methods:
- Review of clinical presentation of acute porphyric crises.
- Discussion of established and emerging therapeutic approaches.
- Focus on treatments influencing the heme biosynthetic pathway.
Main Results:
- Identification of key neurological and systemic symptoms in acute attacks.
- Outline of supportive care and specific treatments for symptom management.
- Highlighting therapies that reduce the activity of the heme biosynthetic pathway.
Conclusions:
- Acute neurological crises in porphyrias are manageable with correct and timely intervention.
- Mortality is preventable with appropriate clinical management.
- Targeting the heme biosynthetic pathway offers specific therapeutic benefits.

01:14Prevention of Further Absorption of Poison
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...
01:23Gastritis III: Clinical Manifestations and Management
The clinical manifestations of gastritis can vary depending on the cause and type of gastritis, but some common symptoms may include the following.
Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...

01:27Acute Pancreatitis I: Introduction
Pancreatitis is inflammation of the pancreas, an organ located behind the stomach. It can be either acute or chronic.
Acute pancreatitis is characterized by rapid inflammation of the pancreas, often caused by factors like gallstone blockage or excessive alcohol consumption. Chronic pancreatitis, on the other hand, is a slow, progressive inflammation that may result from long-term alcohol abuse, obstructions in the pancreatic duct, or genetic factors.
The causes of acute pancreatitis include:

01:30Acute Pancreatitis II: Clinical Manifestations and Management
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...
01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:25Acute Pancreatitis I: Introduction
Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
