ABSTRACT
Acute respiratory distress syndrome (ARDS) is an atypical presentation of scrub typhus infection with associated high morbidity and mortality compared to uncomplicated scrub typhus infection. Here we report an otherwise healthy 41-year-old female patient admitted with moderate ARDS secondary to scrub typhus infection who gained comparatively rapid recovery within 72 hours following intravenous methylprednisolone pulse (MPP) therapy with therapeutic plasma exchange (TPE), suggesting a beneficial role of MPP and TPE in the treatment of ARDS secondary to scrub typhus infection. To our knowledge, this is the first case report regarding the use of MPP therapy and TPE in a patient with ARDS due to scrub typhus infection.
ABSTRACT
Kounis syndrome is the occurrence of acute coronary syndrome associated with mast cell and platelet activation in the setting of allergic or anaphylactic insults. Kounis syndrome has been previously reported following snake envenoming rarely, with or without antivenom therapy. We report a case of inferolateral ST elevation myocardial infarction 32 hours from a confirmed Russell's viper bite. He also had an anaphylactic reaction soon after antivenom. The absence of underlying atheromatous coronary artery disease during subsequent cardiac imaging was suggestive of a diagnosis of a type I variant of Kounis syndrome. Chest pain completely resolved by day 6 following initiation of standard treatment for acute coronary syndrome. Concurrence of allergic features and acute coronary syndrome in a snakebite patient following antivenom therapy should alert clinicians to the possibility of Kounis syndrome, which should be diagnosed with a high degree of clinical suspicion.
