Title: Predictors of mortality in Metformin associated lactic acidosis<br/>Author: Hong Kim<br/><a href='http://umem.org/profiles/faculty/526/'>[Click to email author]</a><hr/><p> </p> <p> Metformin associated lactic acidosis (MALA) has a high rate of mortality, ranging from 25% to 50%. Lactate level and acidemia are frequently associated with poor clinical outcome in many disease/medical conditions (e.g. sepsis).</p> <p> A study investigated, via meta-analysis, if lactate level and pH were predictive of mortality in MALA.</p> <p> <strong>Results</strong></p> <p> 44 studies were identified from PubMed, EMBASE and Web of Science.</p> <p> 170 cases of MALA were included</p> <ul> <li> Median age: 68.5 years</li> <li> Median pH: 7.02</li> <li> Median lactate: 14,45 mmol/L</li> <li> Overall mortality: 36.2%</li> </ul> <p> pH and lactate were poor predictors of mortality based upon ROC curve</p> <ul> <li> pH: AUC of 0.430</li> <li> lactate: AUC of 0.593</li> </ul> <p> <strong>Conclusion</strong></p> <ul> <li> MALA was associated with high mortality in this meta-analysis: 36.2%</li> <li> pH and lactate were poor predictors of mortality. </li> </ul>
