| Popis: | Background Posaconazole-induced pseudohyperaldosteronism (PIPH) has been associated with elevated posaconazole serum concentrations. Clinicians are faced with the difficult task of managing patients with PIPH while not compromising the efficacy of antifungal prophylaxis or treatment. Commonly, modifications to posaconazole therapy are utilized in managing PIPH including dosage reduction of posaconazole or therapeutic switch to an alternative antifungal. Methods We retrospectively reviewed 20 consecutive adult patients diagnosed with PIPH in this case series. Patient data including blood pressure, electrolytes, endocrine laboratory values, and posaconazole serum concentrations collected before and after therapeutic intervention. Results Out of 20 patients included, 17 patients (85%) underwent therapeutic modification with posaconazole dose reduction (N=11) as the most common change. Other modifications included posaconazole discontinuation (N=3), switch to an alternative antifungal (N=2), and addition of spironolactone (N=1). Clinical improvement (a decrease in systolic blood pressure and increase in serum potassium) was observed in 9 of 17 patients (52.9%). Table 1.

Management of Posaconazole-Induced Pseudohyperaldosteronism - p3 Conclusion We report our experience with PIPH management, for which there is currently no universally effective strategy. We suggest a stepwise approach for PIPH management, starting with posaconazole dose reduction and repeat assessment of clinical and laboratory parameters. If resolution of PIPH is not achieved, an alternative triazole antifungal or the addition of an aldosterone antagonist are additional potential interventions. Even with this approach, it is possible for PIPH to persist after therapeutic modification. Thus, early diagnosis and continuous, close monitoring of patients is warranted.
