Metabolic Acidosis in Acetaminophen Overdose without Concurrent Liver Toxicity
نویسندگان
چکیده
Introduction Metabolic acidosis and coma are common complications of acetaminophen overdose. These affects are usually attributed to massive hepatic necrosis caused by Nacetyl-p-benzoquinoneimine (NAPQI), a toxic metabolite of acetaminophen. We describe an unusual case of lactic acidosis and coma in a patient with acetaminophen toxicity without associated hepatocellular damage as the identifiable cause.

Metabolic Acidosis Vs Transaminases Level in Diagnosis and Predicting Prognosis of Acetaminophen Poisoning
Background: Paracetamol (APAP) is the most famous drug used in the world to relieve of pain and used as an antipyretic. Paracetamol overdose induces liver damage and is a well known hepatotoxic drug. This study was aimed to determine the incidence of acidosis in acetaminophen overdose with the time of NAcetyl Cystiene (NAC) administration and correlation of late acidosis and death in acetaminop...

Acetaminophen overdose causes toxicity in liver and extrahepatic tissues. Although it is well established that cytochrome P450 enzymes play a critical role in the metabolic activation of acetaminophen, it is not yet clear whether acetaminophen toxicity in extrahepatic tissues is a consequence of hepatic biotransformation. The aim of this study was to determine whether extrahepatic acetaminophen...

We report a patient with glutathione synthetase (GS) deficiency who developed acetaminophen-induced hepatotoxicity after a two-day treatment with regular doses of acetaminophen. A nine-month-old female was referred because of intractable metabolic acidosis. She was given acetaminophen at therapeutic doses over a 48-hour period. She was hospitalized because of confusion and metabolic acidosis. L...
متن کاملRinger's lactate improves liver recovery in a murine model of acetaminophen toxicity
BACKGROUND Acetaminophen (APAP) overdose induces massive hepatocyte necrosis. Liver regeneration is a vital process for survival after a toxic insult. Since hepatocytes are mostly in a quiescent state (G0), the regeneration process requires the priming of hepatocytes by cytokines such as TNF-α and IL-6. Ringer's lactate solution (RLS) has been shown to increase serum TNF-α and IL-6 in patients ...

In 28 patients with fulminant hepatic failure alkalaemia was present in 49 of a total of 65 observations. Alkalaemia was due primarlily to a low Pa, C02 in 30 instances and to raised plasma bicarbonate in 16 instances. Blood lactate, pyruvate, and acetoacetate were significantly raised, and in individual cases, blood citrate, succinate, and fumarate were elevated. Blood citrate rose progressive...
