EBV
A HERPES FAMILY VIRUS
INFECTS B CELLS—–INCITES AN ABSOLUTE LYMPHOCYTOSIS
ACTIVATES ATYPICAL T-LYMPHOCYTES=DOWNEY CELLS
ABSOLUTE LYMPHOCYTOSIS (>50%) WITH > 10-50% ATYPICAL REACTIVE T-LYMPHOCYTES (DOWNEY CELLS)
ELEVATES LFT’S
LOW ESR
HETEROPHILE ANTIBODY = + SERUM AB TO HORSE RBC’S—-=MONOSPOT TEST
CHILDREN LESS THAN 10 USUALLY TEST –
15% DO NOT TURN + FOR WEEKS
FALSE + IS COMMON WITH CECLOR(SERUM SICKNESS), RA, HODGKINS, BRUCELLOSIS, HEPATITIS
PAUL-BUNNELL HETEROPHILE AB TEST = SERUM AB TO SHEEP RBC’S
IF NEGATIVE
GET EBV AB (IGG OR IGM), VCA (VIRAL CAPSID AG), EBNA (EBV NUCLEAR AG)
ONLY 60% OF PTS WILL HAVE A POSITIVE TEST WITHIN THE FIRST 2 WEEKS—90% TURN POSITIVE WITHIN 1 MONTH
MONONUCLEOSIS (EBV CAUSES 90%)—CAN ALSO BE CMV, TOXO, RUBELLA, HAV, ADENOVIRUS–ALSO CAUSES ATYPICAL LYMPHOCYTOSIS—-CMV–URINE CULTURE AFTER INNOCULATION IN HUMAN DIPLOID TISSUE CULTURE
FATIGUE, ODYNOPHAGIA, CHILLS, DYSPNEA, DEHYDRATION
EXUDATIVE TONSILLOPHARYNGITIS—-REFRACTORY TO ABX,  FEVER, FATIGUE, LAD, 50% H-S MEGALLY, POST TRIANGLE LAD, RARELY ASEPTIC MENINGITIS
LOW ESR, HEMOLYTIC ANEMIA, THROMBOCYTOPENIC PURPURA, JAUNDICE, NEURO ABNL, AIRWAY COMPROMISE
Dx: CBC WITH PBS, MONOSPOT, Hx, PE
Rx: 1 L NS WITH 10 MG DECADRON, 10 MG COMPAZINE, AND 1 G ROCEPHIN—–THEN SEND HOME ON MEDROL DOSE PACK AND T#3—STEROIDS (DECADRON 10 MG 1V Q 6 OR MEDROL DOSE PACK OR 16 MG P.O. QOD X 2), FLAGYL OR CLEOCIN HELPS WITH TONSILLOPHARYNGITIS INFLAMMATION OF SUPERINFXN AND OVERGROWTH OF ANAEROBES
IF REALLY BAD THINK OF A NASAL TRUMPET—POSSIBLE INTUBATION WITH IMMEDIATE TONSILLECTOMY
