Aug 13, 2021 · A similar mechanism also explains why patients who inhale toluene (via “glue sniffing” or spray paint inhalation) often present with severe hyperchloremic hypokalemic metabolic acidosis. Respiratory acidosis and alkalosis can also arise, commonly due to central stimulation or depression of ventilation. Rarely, both can result in death. Methanol exposure can be extremely dangerous, with significant morbidity and mortality if left untreated. Jan 1, 2012 · Inhalation of toluene leads to a classic hyperproduction of metabolic acidosis because of the metabolism of toluene to hippuric acid, which is readily excreted by the kidney with Na +, K +, and NH +4 . 35 and a low HCO3 level. A possible mechanism of sudden sniffing death related to toluene abuse is ventricular arrhythmias, yet the true mechanism is still unknown. Abnormalities of the plasma potassium concentration are also common, due 8. , 4. Liver injury and rhabdomyolysis are common. In a review of cases of toluene abuse, metabolic acidosis was observed in 87% of patients. 20 Large ingestions of ethanol can produce metabolic acidosis due to its metabolism to acetic acid. Toluene may also cause significant renal damage especially with chronic use. In this case, at the emergency department, he was immediately intubated due to acute respiratory failure type 2. This work presents the case of a young woman who had a normal anion gap metabolic acidosis due to toluene sniffing and an unexpectedly low urine anions gap, and the challenges in interpretation of the urineAnion gap and ammonia excretion in the setting of distal renal tubular acidosisdue to toLUene toxicity. Metabolic acidosis is a clinical disturbance characterized by an increase in plasma acidity. 24). Rationale: Hypokalemia is a common finding. According to Carlisle et al. A 21-year-old woman developed severe muscle paralysis after sniffing toluene-containing thinner solution for 2 weeks. A metabolic acidosis reduces the plasma bicarbonate and blood pH. Toluene (methylbenzene, toluol, phenylmethane) is an aromatic hydrocarbon (C7 H8) commonly used as an industrial solvent for the manufacturing of paints, chemicals, pharmaceuticals, and rubber. Hypophosphataemia with such a low phosphate level after toluene poisoning has been rarely reported in the literature. Initial laboratory workup was notable for profound hypokalemia with a serum potassium level of 1. Although they are often used interchangeably, “acidosis” is separate from “acidemia,” which is a serum pH lower than 7. Toluene sniffing, frequently described under the generic category of "glue sniffing Jun 1, 2012 · Abstract. Objective: To identify the clinical and metabolic alterations associated with toluene intoxication. The cause of death was in all cases due to cardiac rhythm abnormalities. Aug 18, 2015 · The hallmarks of acute toluene intoxication are hypokalemic paralysis and metabolic acidosis. Important toxicological considerations for metabolic acidosis are salicylates, acetaminophen, iron, carbon monoxide, cyanide, alcoholic ketoacidosis, and ingestion of other alcohols, such as methanol, diethylene glycol, or toluene. Toluene toxicity as a cause of elevated anion gap metabolic acidosis. 7. 6 Nov 14, 2023 · Metabolic Acidosis: Ethylene glycol is metabolized in the body to toxic byproducts, such as glycolic acid and oxalic acid, which can lead to severe metabolic acidosis. 4°C); therefore, it is a significant fire hazard at room temperature. M – M ethanol (formic acid), metformin. Her electrolyte and acid-base status returned to normal 4 days after cessation of toluene sniffing. A study in 1038 adults with non-dialysis CKD stages 2-5 showed that the prevalence of metabolic acidosis is 7% in CKD-2, 13% in CKD-3 and 40% in CKD-4/5 [57]. An elevated anion gap metabolic acidosis can be caused by salicylate toxicity, diabetic ketoacidosis, and uremia (MUDPILES). Understanding the physiological pH buffering system is important. Acute toluene toxicity causes neurological changes as well as various metabolic alterations. The most common causes of a high anion gap metabolic acidosis are. 3 Hyperchloremic metabolic acidosis, hypokalemia and acute renal insufficiency due to extracellular volume concentration were salient presenting features. The result is non-anion gap metabolic acidosis and K + depletion. Patients with toluene toxicity may initially be suspected of having ethylene glycol toxicity especially as the presentation may be similar (eg a patient with mental obtundation, appearance of intoxication and a metabolic acidosis). On the other hand, the final product of toluene metabolism, hippuric acid can accumulate, elevating the anion gap and causing a high anion Apr 11, 2022 · Next: Imaging Studies. Therefore, intoxication with ethylene glycol should not be misdiagnosed as lactic acidosis in patients with metabolic acidosis and elevated lactate levels. Toluene inhalation is a common form of drug abuse throughout the world. Liver injury and Mar 23, 2010 · Metabolic acidosis is a common acid–base disorder that can occur acutely (lasting minutes to several days) or chronically (lasting weeks to years).

[6] In the present case, the initial venous blood gas showed a pH of 6. It is a metabolic disturbance producing an increase in [H +] or a decrease in [HCO 3− ]. Toluene itself is not an acid but is rapidly metabolized to benzoic (benzyl) acid, which is then quickly converted to hippuric acid. Inhalation of toluene (eg by 'glue-sniffing') may cause either a high anion-gap or a normal anion gap acidosis. Email to a Friend To our knowledge, only one article has reported the association between toluene inhalation and metabolic acidosis, and the findings were consistent with distal renal tubular acidosis (RTA). Generalised weakness is a common complaint. e. Dec 16, 2015 · Isopropanol alcohol, due to the absence of an alpha-carbon, could only be metabolized to a keto- group and contributes to an osmolar gap but not high anion gap metabolic acidosis in poisoning encounters. Mar 20, 2023 · However, acute toluene toxicity affects all body organs and produces remarkable alterations such as metabolic acidosis, hypokalemic paralysis, rhabdomyolysis, and liver injury.

Metabolic acidosis produced by drugs and/or chemicals can be conveniently divided into those with an increase in the anion gap (anion gap = Na- (Cl + HCO3)) and those with a normal anion gap. Toluene intoxication has long been associated with the development of type 1 (distal) renal tubular acidosis (RTA), which causes a normal anion gap hyperchloremic metabolic acidosis and hypokalemia . Close attention is required to patients with severe metabolic acidosis, and though an anion gap is helpful in suspecting and making the diagnosis, the appearance of an anion gap depends on the timing of the alcohol ingestion. The use of May 8, 2023 · Normal physiological pH is 7. Respir Care. 6 Hypokalemia in toluene intoxication is caused primarily by increased renal potassium loss secondary to increased excretion of hippurate, a major metabolite of toluene. The effect of toluene and causes of weakness and hypokalaemia in this setting are discussed. Nov 3, 2020 · Hydrocarbon toxicity.

Exposure to hydrocarbons is common because these substances are readily found in products like kerosene, gasoline, household cleansers, furniture polish A temporal relation between the metabolic acidosis and toluene inhalation was consistently present in both patients, and high levels of toluene were demonstrated in their blood. The severity of clinical presentation and treatment depends on the underlying cause of the metabolic disorder. Therefore, we need not consider the various causes of hypertensive or normotensive renal potassium wasting with metabolic alkalosis. While some disease processes and ingestions are easily excluded, diagnosing toxic alcohol (TA) ingestion can be challenging. Context: Toluene inhalation is a common form of drug abuse throughout the world.
