A

1st line treatment: penicillin

20
Q

when to test toxo in pregnancy

A

not indicated

only in symptoms (fever, nodes, malaise)

21

HCV in pregnancy - complications

A
  1. gestational DM
  2. Cholestasis of pregnancy
  3. preterm delivery
24
Q

HCV - maternal management

A
  1. Ribavirin is teratogenic (avoid)
  2. no indication for barrier protection in serodiscordant, nonogamous couples
  3. HAV + HBV vaccination
25
Q

HCV in pregnancy - prevention of vertical transmission

A
  1. vertical transmission strongly associated with maternal viral load (+ HIV coinfection)
  2. C- section is not protective
  3. Scalp electrodes should be avoideed
  4. Sbreastfeeding should be encouraged unless maternal blood present
26
Q

treatment of chronic HCV in non pregnant

A

inf-a and ribavirin

27
Q

HIV management during pregnancy - anterpartum

A
  1. HIV RNA viral load at initial visit, every 2-4 wks after initiation or change of therapy, monthly until undetectable, then every 3 months
  2. CD4 every 3-6 months
  3. Resistance testing if not previously performed
  4. ART initiation NOW
  5. avoid amniocentesis unless viral load less than 1000
28
Q

HIV management during pregnancy - intrapartum

A
  • avoid artificial rupture of membranes, fetal scalp electrode, operative vaginal delivery
  • viral load less than 1000: ART + vaginal delivery
  • viral load more than 1000: ART + zidovudine + c-section
29
Q

HIV management during pregnancy - postpartum

A

mother: continue ART
infant: maternal viral load less than 1000: zidovudine
more than 1000: multi-drug ART

30
Q
