RESUMEN
Povidone-iodine (PI) is considered a generally safe broad-spectrum, antiseptic substance, which is widely used in healthcare services, mostly for burn patients, in wound treatment, surgical wound irrigation, as well as for a few gynecological indications. Although it is safe, its use on mucosa can cause toxicity due to iodine absorption and the high concentration in the serum. PI toxicity is absorption depended and has been associated with severe adverse events including acute kidney injury (AKI). To our knowledge, there are only three cases of PI-induced AKI after uterine instillation in the published literature. We report a case of severe PI-induced AKI that occurred in a 23-year-old female due to iodine systemic absorption immediately post uterine instillation, in terms of infertility evaluation. The patient was admitted to the intensive care unit (ICU), supported with mechanical ventilation and treated with renal replacement therapy (RRT). Renal function and urine output improved and the patient was discharged from ICU. Severe adverse events may be linked to internal use, therefore, PI on mucosa should be used with extreme caution. Clinicians should be aware of iodine intoxication and possible AKI.
RESUMEN
Epstein-Barr virus (EBV)-related haemophagocytic lymphohistiocytosis (EBVr-HLH) has a better prognosis when the virus is rapidly cleared, but the best antiviral approach is controversial. We present a patient to whom the therapeutic standard rituximab was co-administered with valacyclovir and an HLH-specific treatment with favourable viral and clinical responses. We conducted an extensive literature review and contacted several world reference centres and experts to inquire about their approaches and experience. We conclude that antivirals are infrequently used for EBVr-HLH, despite their laboratory-proven and likely clinical beneficial effect on some EBV-related diseases. However, the role of antivirals remains obscure. Concerns about their lack of efficacy are based on observational data and reports of the cellular tropism of EBV. Therefore, the adjunct use of antivirals may be considered when myelotoxicity is not the primary concern, and related outcomes should be systematically recorded to produce higher quality evidence.
