Title: Herpes simplex virus type 1 and normal protein permeability in the lungs of critically ill patients: a case for low pathogenicity? Cord-id: eiqypt0m Document date: 2004_3_31
ID: eiqypt0m
Snippet: INTRODUCTION: The pathogenicity of late respiratory infections with herpes simplex virus type 1 (HSV-1) in the critically ill is unclear. METHODS: In four critically ill patients with persistent pulmonary infiltrates of unknown origin and isolation of HSV-1 from tracheal aspirate or bronchoalveolar lavage fluid, at 7 (1–11) days after start of mechanical ventilatory support, a pulmonary leak index (PLI) for (67)Gallium ((67)Ga)-transferrin (upper limit of normal 14.1 × 10(-3)/min) was measure
Document: INTRODUCTION: The pathogenicity of late respiratory infections with herpes simplex virus type 1 (HSV-1) in the critically ill is unclear. METHODS: In four critically ill patients with persistent pulmonary infiltrates of unknown origin and isolation of HSV-1 from tracheal aspirate or bronchoalveolar lavage fluid, at 7 (1–11) days after start of mechanical ventilatory support, a pulmonary leak index (PLI) for (67)Gallium ((67)Ga)-transferrin (upper limit of normal 14.1 × 10(-3)/min) was measured. RESULTS: The PLI ranged between 7.5 and 14.0 × 10(-3)/min in the study patients. Two patients received a course of acyclovir and all survived. CONCLUSIONS: The normal capillary permeability observed in the lungs argues against pathogenicity of HSV-1 in the critically ill, and favors that isolation of the virus reflects reactivation in the course of serious illness and immunodepresssion, rather than primary or superimposed infection in the lungs.
