Echinocandins and coagulation dysfunction events.

Despite the recently reported real-world evidence of the signals between echinocandins and coagulation dysfunction events, there are some concerns that may impact the robustness and implications of these findings. For the study design, combining hypercoagulation and hypocoagulation into a single category, "coagulation dysfunction events," may introduce data heterogeneity and complicate interpretation. Possible misclassification of thrombocytopenia and platelet count decreases in spontaneous reports could influence the results and their implications for surveillance activities. For the statistical methods, the analysis reported only crude signal estimates without adjustments for potential confounders. In some comparisons, using Pearson's Chi-square test was inappropriate to investigate the strength or direction of the signals. For the data interpretation, the use of "time to onset" could be misleading without confirmation of temporality (e.g., events detected on day 0 could have occurred before antifungal initiation). Translating pharmacovigilance signals into predictability without evidence of stronger association was also inappropriate. Addressing these issues could strengthen the insights into echinocandins-induced coagulation dysfunctions and expedite further investigation into these adverse events.
