Metformin-Induced Lactic Acidosis: A Question of Time

Abstract: Metformin is an oral antidiabetic largely prescribed in the treatment of type II diabetes. Overdose is associated with life-threatening lactic acidosis. We report the case of the highest metformin concentration ever described secondary to a voluntary suicidal intake. The patient developed a severe lactic acidosis and hemodynamic shock successfully treated with high-flow hemofiltration. Time to start extrarenal epuration is capital to avoid poor evolution.

“…We mathematically estimated that citrate accumulation in an ideal 70 kg patient with no citrate metabolism would reach a plateau concentration of about 7 mmol/L (21 mEq/L) within 48 h. In line with other authors [36][37][38][39]46], our data do not suggest that citrate accumulated, despite the high degree of metformin intoxication measured in our patients.…”

“…Метформинът е перорален противодиабетичен препарат от групата на бигванидините, навлязъл в масова употреба след 1995 г. и понастоящем широко използван в света като лекарство на първа линия за лечение на захарен диабет тип 2 при възрастни [2-3], в много страни е в топ 10 на най-често предписваните медикаменти (до 1.5% от всички прескрипции в Италия например, 7-мо място в САЩ) [2,4].…”

“…В случая на описаната от пациентка клиничната картина се владееше от прогресираща хемодинамична нестабилност, с необходимост от покачващи се дози катехоламини и нарушения, количествени, в съзнанието, като пациентката не бе в състояние да съобщи или потвърди другите типични начални симптоми на метформинова интоксикация, а именно главоболие, абдоминални болки, повръщане [4,8].…”

“…2022 July; 1 ( In addition, it suppresses the lactate metabolism in the liver, inhibits mitochondrial respiration and also exerts a negative inotropic action on the heart, all of which lead to lactatemia (17,18,19). Development of acidemia may take 6 to 24 hours and severe acidemia can lead to altered mental status, coma, hypotension, and respiratory insufficiency and it is often associated with acute kidney injury (20,21).…”
