Viruses - HHV Family

*HHV = Human Herpes
Virus Family

  • 8 subtypes
  • go in order of importance
    --> HSV 1/2 (mouth/genitals)
    --> VZV (varicella/zoster shingles)
    --> HHV4 = EBV (infectious mono)
    --> HHV5 = Cytomegaly virus (SIGHTO / immuno suppress)
  • Double stranded and enveloped DNA virus family
    --> think HHV has Double HH protection + enVeloped hhV
  • HSV1 / HSV2 = "FIRST you KISS, 2nd you FUCK"
    --> HSV1 = oral cavity + cribiform plate (herpes labialis = cold sore)
    --> HSV2 = genitals (herpes genitalis)

*COMMON HHV - Healthy people HHV Viruses

  • includes HHV 1 - 4
  • HSV- 1 and 2
  • VCV - kids = Varicella chicken pox
  • VCV - elderly = Zoster shingles
  • HHV 4 = EBV = Ebstein Barr virus = mononucleosis in teens

*HIV / Immunosupressed HHV Viruses

  • includes HHV 5 - 8
  • HHV 5 = CMV
    --> (one of the most common infections in HIV people)
  • HHV 6/7 = Infant ROSEOLA Herpes Virus
    --> ("ROSEOLA = fever first, ROSY cheeks LATER")
  • HHV 8 = Adult Kaposi Sarcoma Herpes
    --> Kaposi sarcoma = neoplasm of endothelial cells

HHV-4
(*EBV = Epstein-Barr Virus)

  • Ebstein Barr Virus
    --> Bcells CD 21
    --> Burkitt Lymphoma

Notes:

  • almost 90% of the population has EBV by their late teens, though many infections are unsymptomatic

HHV-3
(*VZV= Varicella-Zoster Virus)
(chicken pox / shingles)

Notes:

  • primary V-Z virus = chicken pox
  • secondary V-Z virus = shingles

*CMV = HHV5 (Cytomegalovirus)

  • CYTO - MEGALO transplant
    --> "sighto" --> affects the eyes
    --> retinitis
    --> MEGAlow transplant = infects lung transplants
  • Cyto is an opportunistic virus
    --> HIV, congenita
  • most common in lung transplants
    --> post 3 monthss

*Kaposi Sarcoma HHV 8 Viruse

  • HHV 8 = Adult Kaposi Sarcoma Herpes
    --> Kaposi sarcoma = neoplasm of endothelial cells

*ROSEOLAS Infant HHV 6/7 Viruse

  • HHV 6/7 = Infant ROSEOLA Herpes Virus
    --> ("ROSEOLA = fever first, ROSY cheeks LATER")

HSV type 1 and 2

  • Tzank test for antigens
  • "TZANK Heavens I don't have HERPES"

*HSV 1
(Herpes Simplex Virus 1)
(cold sores)

  • HSV1 / HSV2 = "FIRST you KISS, 2nd you FUCK"
    --> HSV1 = oral cavity + cribiform plate (herpes labialis = cold sore)
    --> HSV2 = genitals (herpes genitalis)
  • HSV1 / HSV2 = "ONE BRAIN, 2 MENINGES"
    --> HSV1 = encephalitis
    --> HSV2 = meningitis
  • HSV1 = most common cause of sporadic encephalitis
  • HSV1 gives you 2 TEMPORARY things:
    --> " TEMPORARY LABLIAS and TEMPORAL LOBE enchepalitis
    --> Herpes labialis
    --> HSV1 most common cause of sporadic temporal enceph in young people

Notes:

  • HSV-1 usually affects the mouth, but can be spread to the genitals
  • HSV1 / HSV2 = "FIRST you KISS, 2nd you FUCK"
    --> HSV1 = oral cavity + cribiform plate (herpes labialis = cold sore)
    --> HSV2 = genitals (herpes genitalis)

*HSV 2
(Herpes Simplex Virus 2)

  • HSV1 / HSV2 = "FIRST you KISS, 2nd you FUCK"
    --> HSV1 = oral cavity + cribiform plate (herpes labialis = cold sore)
    --> HSV2 = genitals (herpes genitalis)

Notes:

  • HSV-2 usually affects the genitals, but can be spread to the oral route

*Tzank test for HSV

  • "TZANK Heavens I don't have HERPES"
  • Tzank smear of HSV-1 ulcers shows giant cells that are multinucleated

  • secondary to EBV usually
  • reactive macrophages release perforin and granzymes
  • granzymes = granular enzymes = grandiose apoptosis

Notes:

  • they have cytotoxic granuoles = perforin and granzymes

*Zoster virus = Shingles

dropped image link

*PHN = Post herpetic Neuralgia treatment

  • happens weeks to months after having shingles or reactivation of VZV
  • 1st line = TCAs, pregabalin and gabapentin
  • 2nd line = lidocaine patch, topical capsacin
  • "TRY Trys and GABAs first in BURNING neuropathic pain... before you TRY oppening a LID of HOT PEPPERS on it".
    --> TRY Trys and GABAs = 1st line TCA and gabapentin
    --> LID of HOT PEPPERS = 2nd line lidocaine and capsaicin

Example:

Notes:

  • think of when HSV 1 comes into the skin initially by saliva, it is transported to the nerve cell body by dinesin trasnport retrograde
  • it then incorporates into the DNA of that nerve cell, usually the trigeminal nerve
  • when activated it is transported down the axon by kines = anterograde trasnport

and Sequelae

Notes:

  • HSV-1 since it gives oral lesions, it can infect the olfactory tract
  • it then travels to the olfactory cortex of the temporal lobe and can cause temporal encaphalitis
  • commonly present with headache, fever, Hx of HSV-1 and personality/mood changes
  • Treatment
    --> IV acyclovir

Notes:

  • note that

*INfectious Mononucleosis

  • caused by both EBV and CMV
    --> HHV 4 + HHV 5
  • note that CMV MONO is monospot NEGATIVE
    --> NOT picked up by the MONOSPOT TEST

MONKEY NUCLEAR PLANT poisons the SMALL TOWN LAKE and makes the ANIMALS and CREATURES in the lake MUTATE and attack the TOWNS PEOPLE


  • first a HERPES HARP = 4/5 emerges from the MONKEY NUCLEAR LAKE and makes a YOUNG TEENAGER very SLEEPY
  • 2nd a FEAVER BEAVER comes out of the MONKEY NUCLEAR LAKE and punches a girl in the head and back to give her many ACHES

then next the SUPERHERO = SWOLLEN LIMES in ARMPITS and NECK MAN comes floating down on his INFLATED HEPATOMEGALY BALOON and SPLENOMEGALY BALLOON


  • SUPERHERO SWOLLEN LIMES in ARMPITS and NECK MAN then throws his SWOLLEN LIMES at the MONKEY NUCLEAR plant and kills the MONKEY
  • the MONKEY emerges from the wreck with a large RASH all over his body
    --> diffuse rash happens in EBV when people with MONO / EBV think they have a STREP throat infection and take amoxacillin
    --> they then get a huge diffuse rash on their body

at the end of the MONKEY NUCLEAR plant SAGA the MONOCYTE MAYOR of the small town gives SUPERHERO SWOLLEN LIMES in ARMPITS and NECK a MONOSPOT + certificate
--> MONOSPOT + test for EBV
--> note this is NEGATIVE for CMV type MONO

EINSTEIN BAR VIRUS is double stranded DNA LIMBO BAR with the MONONUCLEOSIS MONKEY holding the PRIZE money in the ENVELOPE


the MONONUCLEOSIS MONKEY is very talented and is holding the PRIZE MONEY ENVELOP in one HAND and in the other a BASKETBALL with CD21 BLACK JACK CARDS


  • EINSTEIN BAR VIRUS gets into B cells through the CD 21 marker

CANCERS associated with EINSTEIN BAR DISEASE


  • NASO PHAROAH in CAR WITH GNOME are throwing LIMES at the MONONUCLEOSIS MONKEY and trying to knock him over from their BUCKET OF LIME FOAMS
    --> EINSTEIN BAR VIRUS can give NASOPHARYNGEAL CARCINOMA
    --> also BURKIT B CELL LYMPHOMA
  • there is the LION KING HOG KING also with LIME FOAMS
    --> EINSTEIN BAR VIRUS causes HODGEKINS LYMPHOMA

  • SIDETOE MEGALO TRAINS PLANTS is an eveloped DS DNA virus

the TRAINS PLAINS has a HERPES HARP as a train whistle and OWLS EYE INCLUSION lights to make sure they know where they are going


the OWLS EYE INCLUSION lights are not bright enough to see the DS DNA track


they can't see anything at all

  • so SIDE TOE driving the TRAINS PLANTS puts his BABY on the front of the TRAINS PLANTS and gives hima TORCHES to hold to light the DNA TRACK
  • but he still can't see...

just then the SIDE TOW driving the TRAINS PLANTS gets distracted by a NUDE MONA picture of JAN in JAMICA JANCYCLOVIR and runs over a BAND AID and RED EYES on a SARCOPHAGUS ESOPHAGUS and
