Patient’s labs are significant for a white count of 14,000, with 75% neutrophils. Chemistries are significant for having a creatinine of 1.15.  LDH is 330, total protein is 7.2. Fluid analysis shows a cloudy turbulent fluid.  Thoracentesis fluid reveals :WBCs  20000/ml-  neutrophils 85%, Lymphocytes 10%.  Glucose is 20.  LDH 250.  Total protein 5.6.  PH is 7.1 Gram stain reveals large numbers of neutrophils with occasional gram positive cocci.   What is the most likely cause of patient’s pleural effusion?
