Q
What is bacterial vaginosis?
A
overgrowth of predominately anaerobic organisms such as :
GARDNERELLA VAGINALIS..
leads to fall in lactic acid producing aerobic lactobacilli (friendly bacteria in vagina) = raised vaginal ph.

if sx present : csection
normal delivery if no sx and more than 6 weeks from initial infection.
primary genital herpes contracted after 28 weeks gestation: aciclovir follow immediately by regular prophylactic aciclovir. - c section recommended.

initial seroconversion flu like illness within few weeks of infection. then asx until conditions leads to immunodeficiency.
can be years after
92
transmission of hiv
not through day to day activities like kissing
its through:
unprotected anal, vaginal or oral sex
mother to child at any stage of pregnancy, birth or breastfeeding (vertical transmission)
mucous membrane, blood or open wound exposure to infected blood or bodily fluids (sharing needles, needle-stick injuries or blood splashed in an eye)
93

screening for hiv
can take bloods for hiv in emergency department.
4th gen lab test for hiv checks for antibodies and p24 antigen. window period of 45 days - can take upto 45 days after exposure to the virus for test to turn positive. - negative result within 45 days of exposure is unrealiable. over 45 days after exposure, negative reuslt is reliable.
point of care tests for hiv antibodies: result within minutes. 90 day window period.
home testing kit:
self-sampling - poste dto lab - fourth gen test for antibodies and p24 antigen
point of care test - antibodies only
101
how to monitor for hiv
test cd4 count- number of cd4 cells in blood. cells destroyed by the virus.
lower the count higher the risk of opportunistic infection:
500-1200 cells/mm3 is normal
under 200 cells/mm3 - pt at high risk of opportunistic infections
test for hiv rna per ml of blood: tells you viral load.
undetectable viral load means level below recordable range (usually 20 copies/ml). viral load can be in hundreds of thousands in untreated hiv
102
Investigations for HIV
1st - HIV antibody test - false negative for 3 months post exposure
if negative - repeat in 3 months
confirmatory: repeat p24 or use western blot (p24, gp120, gp41)
103
How does HIV present?
acute (cd4>500)
- flu like symptoms
chronic/latent (cd4 500-200)
-fever
-persistent lymphadenoapthy
-opportunistic infections like ebv causing hairy leukoplakia or oral candidiasis
- tb can reactivate
aids defining
-persistent fever,fatigue, weight loss, diarrhoea, visual loss
104
How would you manage HIV
Antiretrovirals, aim to increase cd4 count and reduce viral load
-2 nucleoside reverse transcriptase inhibitors (nrti) + protease inhibitor or on nucleoside reverse transcriptse inhibitor
eg: tenofovir, emtricitabine and bictegravir
105
How would birth be managed in a women with hiv?
viral load
<50 copies/ml - normal delivery
>50 copies - consider c section
over 400 - pre-labour c section
IV zidovudine if viral load high/unknown during labour. (4 hrs before starting c section)
106
factors in hiv which reduce vertical transmission (from 25-30% to 2 %)
maternal antiretroviral therapy
mode of delivery - c section
neonatal antiretroviral therapy
infant feeding - bottle feeding
107
