Description
Table of Contents Note: With the exception of the Western Blot test, the antibody or antigen test is usually a HIV ELISA test HIV prevention / HIV PEP (post-exposure prophylaxis) treatment can prevent you from getting an HIV infection, and turning HIV positive. Individuals are eligible for HIV PEP Treatment if all the following criteria are met: - less than 72 hours has elapsed since exposure;
and - the exposed individual is not known to be HIV infected;
and - the person who is the source of exposure is HIV infected or has unknown HIV status;
and - mucous membrane or non-intact skin was exposed to a potentially infectious body fluid;
Prompt antiviral therapy may reduce the risk of HIV transmission by as much as 80%. For optimal efficacy, antiretroviral therapy should be started as soon as possible, ideally within 1 hour of exposure. So that you can remain HIV negative. The medications and dosages are the same as those used for lifelong treatment of HIV patients. However, for HIV PEP treatment, it is taken for only a month. Drugs commonly used in HIV PEP: References Remember, there is no HIV cure.

HIV is the abbreviation for the human immunodeficiency virus, which causes the acquired immunodeficiency syndrome HIV symptoms which may present in acute HIV infection: These are nonspecific symptoms and can present with other infections; consequently, they are unreliable indicators of HIV infection. HIV Test The HIV window period is the time from HIV infection until a HIV Test can detect any change. Within the HIV window period, the HIV Test would be negative. During this period, the HIV viral load is extremely high, thus making the person highly infectious. OraQuick® HIV Test Kit / HIV rapid test cost/price is S$60/=. No additional consultation fees are charged if the clinic attendance is only for this test. Window period | Test | Notes | Cost / Price | | 2 weeks | HIV DNA test | - A HIV NAT (nucleic acid test) for HIV-1 proviral DNA
- A HIV PCR (polymerase chain reaction) test. Method: Proviral DNA Polymerase Chain Reaction (Roche Amplicor HIV-1 DNA Test, V1.5) This test uses primers SK145 and SKCC1B to define a sequence of 155 nucleotides within a highly conserved region of the HIV-1 gag gene.
- HIV window period can be as short as 10-12 days
- Usually used for the early diagnosis of HIV infection in neonates born to HIV+ mothers. As maternal antibodies circulate in the child for several months, the HIV antibody test would be positive.
- Patient to arrive at the clinic before 10am (Monday to Friday only)
| SG$752/= | | 1 month | HIV p24 antigen test | - A HIV antigen test that tests for the HIV p24 antigen, which appears in early infection, before the appearance of HIV antibodies. But later declines when the HIV antibodies begin to appear.
- Usually packaged with the HIV-1/2 IgM/G antibody test, to becomes a 4th generation HIV ELISA test
| SG$48/= | | 3 months | OraQuick® | | SG$60/= | | 3 months | HIV blood test most commonly sent to the lab. | | SG$12/= | HIV confirmation | HIV western blot test | | SG$275/= | HIV follow-up | HIV RNA test | - A HIV NAT (nucleic acid test) for HIV-1 RNA of the free virus, giving the HIV viral load
- A HIV PCR (polymerase chain reaction) test. Test Method: Abbott Realtime HIV-1
- Usually used to monitor the progress of HIV+ patients on treatment.
- Patient to arrive at the clinic before 10am (Monday to Friday only)
| SG$717/= | References CD4 count - Used in HIV follow up management
- Cost SG$169/=
- Results return in 1 week.
- CD8 count is also available separately at the same price.

Conclusions
These results suggest that the appropriateness of HIV PEP initiation in the French military should be reviewed. Adapting French guidelines for managing BBF exposure, for non-hospital-based environments should be considered. (Source: Occupational Medicine)
HIV post-exposure prophylaxis programmes in the developed and developing world: can we learn from each other?
Thu, 15 Dec 2011 05:00:00 +0100 | International Journal of STD and ----
In an audit of HIV post-exposure prophylaxis (PEP) programmes in Blantyre, Malawi, and Liverpool, UK, a striking common deficiency was poor attendance of follow-up visits and of HIV testing to determine efficacy of PEP. Causes of poor follow-up after PEP need to be explored in both settings. (Source: International Journal of STD and ----)
A narrative study of exposures to potentially infected body fluids referred to a regional infectious diseases unit: Category: Scientific free paper
Fri, 25 Nov 2011 11:05:46 +0100 | Journal of Infection
Exposure to potentially infected body fluids is a significant occupational hazard for health care workers (HCW). While those not involved in health care work encounter this hazard less frequently, they remain at risk to exposures such as injuries from discarded needles and during assaults. Such exposures, particularly to blood, carry the potential for transmission of infection, most notably hepatitis B, C and HIV, although such events are rare. They are also the source of considerable distress and can result in long-term psychological sequelae. Appropriate initial first aid management of the injury is likely to reduce incidence of transmission and specific measures such as hepatitis B immunoglobulin (HBIG) and vaccination and HIV post-exposure prophylaxis (PEP) can prevent transmission of ...
Use of HIV PEPSE and Hepatitis B vaccine following the introduction of a SARC
Fri, 28 Oct 2011 11:14:23 +0100 | Journal of Forensic and Legal Medicine
Abstract: Adherence to local guidelines on the use of HIV post exposure prophylaxis (PEP) and hepatitis B vaccine following sexual assault was evaluated by means of audit. Forensic Medical Examiners (FMEs) were asked to complete an audit form after conducting sexual offence examinations at Gloucester Sexual Assault Referral Centre (SARC).Only one HIV PEP pack was prescribed during the six and a half month audit period. Examination of the SARC records of the allegations made by complainants did not reveal any high-risk cases involving a failure to offer HIV post-exposure prophylaxis following sexual exposure (PEPSE).The majority of the examinations performed at the SARC were carried out by trained sexual offence examiners (SOEs). The audit indicates that these SOEs were considering the appr...

Preventing Human Immunodeficiency Virus Infection Among Sexual Assault Survivors in Cape Town, South Africa: An Observational Study
Mon, 07 Feb 2011 22:26:26 +0100 | ---- and Behavior
We describe 131 South African sexual assault survivors offered HIV post-exposure prophylaxis (PEP). While the median days
completed was 27 (IQR 27, 28), 34% stopped PEP or missed doses. Controlling for baseline symptoms, PEP was not associated
with symptoms (OR = 1.30, 95% CI = 0.66, 2.64). Factors associated with unprotected sex included prior unprotected sex (OR = 6.46,
95% CI = 3.04, 13.74), time since the assault (OR = 1.33, 95% CI = 1.12, 1.57) and age (OR = 1.30, 95% CI = 1.08, 1.57). Trauma
counseling was protective (OR = 0.18, 95% CI = 0.05, 0.58). Four instances of seroconversion were observed by 6 months (risk = 3.7%,
95% CI = 1.0, 9.1). Proactive foll...
Audit of emergency department assessment and management of patients presenting with community-acquired needle stick injuries.
Tue, 01 Feb 2011 00:00:00 +0100 | Australian Health Review
Conclusion. We have identified groups that are at high risk of CANSI, including young males, security workers and cleaners. In the majority of cases protection against hepatitis B was inadequately provided, and a substantial proportion had inadequate baseline assessment and documentation. A guideline is suggested that may be used to improve these deficits. What is known about this topic? Occupationally acquired needle stick injury guidelines are well established, but no guidelines currently exist for community acquired needle stick injuries (CANSI) which may require different risk stratification, assessment and management. Management of CANSI in Emergency Departments has not been well described. What does this paper add? An audit of Emergency Department management of community acquired nee...
