#idboardreview 20 F w/ SLE on hydroxychloroquine & recently high dose steroids for SLE flare presents w/F, dyspnea, diarrhea, wbc6k, Na133, COVID/RVPneg, procal9, galactomann neg, dx? #meded #idmeded #idtwitter
#Legionella cavitary pneumonia is atypical presentation of Legionnaire’s disease & more commonly w/ impaired cellular immunity due to corticosteroids (particularly high-dose steroid), immunosuppressive therapy, organ transplant & HIV infection; Case Ref idimages
Cavitation seen w/ #Legionella pneumophila serotypes 1,3,4,5,6,8 as well as L. micdadei, L. bozemanae, L. dumoffii, L. longbeachae.
L. pneumophila 1 is main agent of Legionnaire’s disease. Non-serotype 1 & non-pneumophila Legionella occur in severely immunocompromised hosts

#Legionella #longbeachae far less common species in US despite its discovery in Long Beach, California (<5% of legionellosis). L #longbeachae is endemic in Australia & New Zealand
#Legionnaires disease: CAP but more GI sx (N, V, D, abd pain), neurological sx (HA, seizure, FND, obtundation) & labs (low sodium/phosphorus, inc CPK, inc LFTs, inc inflammatory markers, myoglobinurea, microscopic hematuria & relative lymphopenia)
