Q

Post sexual assault, would you offer STI testing if within the window period for GC/CT?

A

If the client presents within 2 weeks of the assault, consider STI screening at baseline using Nucleic Acid Amplification Tests (NAATs) if appropriate and repeat tests 2 weeks after exposure

High rate of default from subsequent appointments, so a pragmatic approach to management may have to be taken.

20
Q

What should be advised with regards to DDI if patient is given Kaletra® (Lopinavir and Ritonavir)

A

Kaletra® (Lopinavir and Ritonavir) reduces the effect of the contraceptive pill through induction of hepatic enzyme activity.

Additional barrier contraception such as condoms should be advised to those on
the combined oral contraceptive pill, patch, an implant (Implanon®) or a progesterone only pill.

The dose of a combined oral contraceptive pill should be adjusted to provide 50 micrograms or more of ethinylestradiol.

21
Q

What should be considered with regards to risk of Hepatitis B infection in sexual assault?

A

Acquisition of Hepatitis B following sexual assault in the UK is very rare.
BASHH guidelines recommend that Hepatitis B vaccine may be considered in those who give a history of a sexual assault up to 6 weeks.

22
Q

When should hepatitis B immunoglobulin be considered?

A

Immunoglobulin should be considered within 48 hours and no later than 7 days after a known infectious contact and may be given to a non-immune contact after a single unprotected sexual exposure, if the assailant is known or strongly suspected to have Hepatitis B

23
Q

Does hepatitis B vaccination precent infection post exposure?

A

There is a theoretical possibility that a very rapid course of Hepatitis B vaccination given within 6 weeks of sexual exposure, apart from offering long term protection, will prevent the development of Hepatitis B infection in those at risk

24
Q

How is Hepatitis B immunoglobulin given?

A

Immunoglobulin 500 i.u. IM (best within 48 hours) no later than 7 days of an known infectious or strongly suspected contact to non-Hepatitis B immune individuals

25
Q

What hepatitis B vaccine regime can be offered?

A

Hepatitis B vaccination 1 ml IM in adults and adolescents > 13 yrs of age within 6 weeks of exposure ( Engerix B 3 x 20 mcg; HBvaxPro 3 x 10 mcg)

Very rapid course of Hepatitis B vaccination given at 0, 7 and 21 days post exposure

Or an accelerated course at baseline, 1 month and 2 months post exposure followed by a booster at one year, is recommended.

26
Q

What are the options for EC in women post sexual assault?

A

Oral EC or IUD
A copper IUD, due its low failure rate and its potential for use as an ongoing method of contraception, ought to be discussed with all women presenting within 5 days after an episode of unprotected sexual exposure

27
Q

Can Oral EC be given if on PEPSE?

A

UPA and levonelle can be given with Truvada and raltegravir. (or alternative PEPSE- zidovudine and lamivudine- depending on what 3rd agent is - beware if ritonavir booster)
No need for double dosing

28
Q

Can oral EC be given if on enzyme inducers?

A

The dose of Levonelle should be doubled (ie: 3 mg) for those taking liver enzyme- inducing drugs.
Those starting HIV PEPSE at the same time should use condoms.
The issue of emergency contraception and simultaneous administration HIV PEPSE raises questions about efficacy and toxicity.
Some clinicians would choose to use a double dose of emergency contraception in case Ritonavir reduces levels.
Liverpool interaction says weak association with ella one and levonelle and ritonavir and unlikely to be clinically significant

29
