23Significance
- In relation to the health of the population of a
country or territory in general ... - ... or of particular populations
- Determined by a range of factors
- Prevalence
- Severity of acute symptomatology
- Transmissibility preventability
- Curability
- Long term consequences or complications
24Human Papilloma Virus
- Non-enveloped DNA virus
- Replicates exclusively in epithelial cells
- Transmitted by skin to skin contact with
microabrasions - Enters cell and modifies cell cycle to maxmise
further transmissibility - Naturally cleared in months to years
- Median duration of infection 8 months, 9
persistent after 2 years1 - Persistence related to
- Infection with multiple types
- Infection with high risk types
- Ho GY et al. Natural history of cervicovaginal
papilloma virus infection in young women. N Engl
J Med 338(7)423-8, 1998
25HPV associated disease
- gt100 genetically related types
- Different types adapted for different skin areas
- Types 16 18 (and others) strongly associated
with cervical carcinoma - Types 6 11 (and others) associated with visible
anogenital warts - Some types also associated with anal, penile and
oral cancers - Islands experience of cancer of cervix and
anogenital warts
26HPV genital warts
27Genital warts diagnosis
28Genital warts treatment
- Lots of different approaches nothing is
perfect! - Most treatment is cosmetic not curative
- Very high recurrence rates
- Imiquimod cream (Aldara)
- Induces local immune response
- 5 cream applied 3x/week for up to 16 wks
- Response is delayed
- Lower recurrence rate
- Contraindicated in pregnancy
- Expensive!
29First line treatment in your centre?
- Podophylotoxin
- Diathermy
- Cryotherapy
- Imiquimod
- Surgical excision
- Nothing
- Something else

36Genital herpes
- HSV spread by skin to skin or mucosa to mucosa
contact with friction - Primary infection at site of entry then lifelong
infection of sensory dorsal ganglia supplying
infected skin/mucosa - Originally
- HSV1 oral cold sores
- HSV2 genital herpes
- Now primary HSV1 is common cause of genital
herpes in developed countries
37Genital herpes
- 1 26 days (usually 6 8 days) after first
acquisition primary infection - Complications of primary infection include
urinary retention, aseptic meningitis and rarely
transverse myelitis - First clinical episode is not always primary
infection
38Genital herpes
39Clinical course of episode
- Prodromal tingling ? vesicles ? ulcers ? crusts ?
healing - All takes 5 7 days but active HSV infection is
the first 48 hours after that it is just
healing - Need to treat episode within first 48 hours or
not worth it (except in people with HIV)

41Genital herpes HIV
Relative risk of acquiring HIV based on HSV2
serology, adjusted for age and sexual behavior

women systematic review and meta-analysis of
longitudinal studies. AIDS 20(1) 7383, 2006
42Genital herpes HIV
- HSV ulcers often coalesce and persist in people
with HIV

- Some evidence of survival benefit in people with
HIV who have HSV if HSV treated - Continuous suppressive therapy certainly
worthwhile if symptomatic
46Take a break!
47Syphilis
- Caused by a spirochaete (spiral bacterium)
Treponema pallidum - Transmitted by skin to skin or mucous membrane
contact with abrasion - Four classical stages
- Primary
- Secondary
- Latent
- Tertiary
- Early syphilis is not always classical
48Primary syphilis
- 9 90 days after exposure
- Appearance of chancre at site of exposure
- Usually single, painless, indurated, sharply
defined edges - Can often be missed (if not penile!)
- Disappears in 3 to 6 weeks if not treated
49Chancres
50Secondary syphilis
- 6 weeks to 6 months after primary infection
- In 1/3rd chancre will still be present
- Fever, malaise, headache, myalgia
- Rash in 80-90
- Classically dark pink macules
- The great mimic
- Can affect palms and soles
- Transient or can last weeks
51Secondary syphilis
52Secondary syphilis
- Mouth ulcers multiple
- Can coalesce ? snail track ulcers
- Rash on scalp can cause hair loss
- Genital lesions condylomata lata
- Rarely neurological complications
- Aseptic meningitis
- Cranial nerve palsies
- More common in people with HIV
- Rarely glomerulonephritis, hepatitis
53Secondary syphilis
54Secondary syphilis
55Latent syphilis
- Asymptomatic
- Now divided into
- Early latent
- Six months to 2 years (1 year in USA)
- Still considered infectious syphilis
- Late latent
- gt 2 years (1 year in USA) and asymptomatic
- Condsidered late syphilis
- Can still be transmitted from mother to child
56Tertiary syphilis
- Four to 30 years from primary infection
- Approximately 1/3rd of patients untreated
- Gummatous (benign)
- Cardiovascular
- Neurosyphilis
57Tertiary syphilis
58Diagnosis of syphilis
- Dark ground illumination of fluid from chancre
- T. pallidum PCR from chancre fluid
- Serological testing
- Non-treponemal tests
- VDRL (Venereal Disease Research Laboratories)
- RPR (Rapid Plasma Reagin)
- Treponemal specific tests
- T. Pallidum haemagglutination assay (TPHA)
- Flourescent treponenal Ab absorbtion (FTA-ABS)
- Treponemal IgG immunoassays
59Syphilis serology
- Non-specific tests (RPR or VDRL) are either
reactive or non-reactive ... - But can measure level of reactivity through
dilution - Useful for monitoring response to treatment
- 11 Reactive with 11 dilution (half half)
but non-reactive at 12 dilution (1/3 to 2/3) - 164 Still reactive when serum diluted 164
ie very high reactivity level - RPR or VDRL can be falsely positive but seldom
gt14, TP specific test will differentiate

66Congenital syphilis
- Occurs when woman with secondary or early latent
becomes pregnant or woman has secondary syphilis
during pregnancy - 40 stillborn
- 40-70 of survivors infected (in utero), of whom
12 will die in infancy - Liver, spleen and bony abnormalities
- Hutchisons triad deafness, Hutchinsons teeth,
interstitial keratitis

71Chlamydia trachomatis
- Gram-negative bacterium
- Obligate intracellular pathogen
- Cannot survive or replicate outside of cells
- Formally classified as rickettsia
- Causes genital infection and eye disease
(trachoma) - Transmitted by fluid (and cell) transfer during
vaginal, anal and oral sex - Asymptomatic in 75 of genitally infected
females and 50 of genitally infected males
72Chlamydia trachomatis
73Chlamydia complications
- Pelvic inflamatory disease (40 of
untreated women) - Female Infertility
- Early spontaneous abortion
- Premature labour
- Neonatal eye disease
- Epididymitis
- Male infertility
- Islands experience of complications?
74Chlamydia diagnosis
- Rapid tests are insensitive and have little value
in asymptomatic screening - Nucleic acid testing on swabs or first pass urine
is gold standard - Stand displacement assay (BD Probetec) now
available in multiple Pacific Island under Global
Fund project islands experience so far?

effectively treated.
98Criteria for effective ART
- Questions and further discussion
- A local partnership between public health
services, clinical services and community
organisations exists to ensure a continuum of
care and support for people taking treatment,
including support for ART adherence - A core multidisciplinary HIV care team has
received appropriate training - Diagnostic services available to perform HIV
antibody tests and essential routine tests to
monitor for drug toxicity - An adequate patient record system exists
