30
Chlamydia Screening
Nucleic acid amplification tests (NAATs) – Highly specific and sensitive – Women: vulvovaginal swab (1st line) - Alternatives: 1st void urine sample or endocervical swab – Men: 1st void urine sample (1st line)
31
chlamydia Tx
FIRST LINE: Doxycycline 100 mg BD for 7 days – c/i in pregnancy & bf – GI side effects common – photosensitivity ALTERNATIVES: – Azithromycin 1 g orally as a single dose for 1 day, followed by 500 mg orally OD for 2 days – Erythromycin 500 mg BD for 10–14 days – Ofloxacin 200 mg BD for 7 days
32
AMR and chlamydia
used 1g single dose azithromycin (SDA) or 7 days doxycycline Mycoplasma genitalium (MGen) - emerging, significant sexually transmitted pathogen, can get co-infection with chlamydia inc prevalence of macrolide resistance in MGen, because of use of SDA to treat STIs SDA less effective than doxycycline SDA no longer recommended
33
Tx for chmalydia in pregnancy
* Azithromycin 1g stat followed by 500mg for 2 days * Erythromycin 500mg twice daily for 14 days * Amoxicillin 500 mg three times a day for 7 days ** doxycycline and ofloxacin are c/i
34
Chlamydia – follow up
* Avoid sexual intercourse (incl oral sex) until the person & partner completed treatment (or waited 7 days after Tx with azithromycin) * Failure of Tx can be due to re-infection * Screen for other STIs * Refer to a GUM clinic for partner notification. – Symptomatic males – all partners within 2 weeks – Asymptomatic - preceding three months should be notified
35
test for cure with chlamydia
A test of cure not routinely recommended
36

gonorrhoea Sx - female
Genital gonorrhoea infection is usually symptomatic in men * Urethral discharge * Dysuria Rectal and pharyngeal – asymptomatic
41
gonorrhoea screening
* A NAAT for the presence of N. Gonorrhoea Women: vulvovaginal swab Men - 1st pass urine sample * Culture required if patient is NAAT positive for gonorrhoea - to test for susceptibility and ID resistant strains
42
AMR and Gonorrhoea
* No class of antimicrobials where resistance hasn’t developed * Strains of MDR are evident - ‘Super gonorrhoea’ - resistant to the most common antibacterials * change 1st line Tx: Tx was dual therapy of ceftriaxone with azithromycin * Ceftriaxone resistance remains rare in the UK
43
Gonorrhoea - treatment
** Tx ideally based on susceptibility susceptibility is not known: - Ceftriaxone 1 g IM injection as a single dose - safe when pregnant/bf susceptibility is known: - Ciprofloxacin 500mg orally as a single dose - pregnancy/bf: Azithromycin 2g orally as a single dose
44
disseminated Gonorrhoea - treatment
* Ceftriaxone 1g IM or IV every 24hrs * Cefotaxime 1g IV every 8hrs 24-48 hours after Sx begin to improve switch to * Cefixime 400 mg twice daily or * Ciprofloxacin 500 mg twice daily (switch should be made guided by sensitivities)
45
Gonorrhoea - follow up
* Avoid sexual intercourse (including oral sex) until Tx completed (or waited 7 days after Tx with azithromycin) * Follow up about 1 week after Tx to: - confirm adherence to Tx and Sx resolution - ask about adverse reactions - confirm that partner notification has been carried out - ask about recent sexual Hx (and the possibility of reinfection) - reinforce advice about safe sexual practice TEST FOR CURE recommended for all people treated for gonorrhoea - asymptomatic - test with NAAT at least 2 weeks after completion of Tx - Sx - test with culture, at least 3 days after completion of Tx - consider additional testing with NAAT after one week if culture is -ve - GUM clinic notification - as for chlamydia - notified partners - test and treat empirically whilst awaiting results - advice on safer sexual practices, contraception and condom use
46
What is HPV?
DOUBLE STRANDED dna VIRUS
47
high risk types of HPV that cause cancer
HPV16 HPV18
48
HPV vaccination
Cevarix - used until 2012 - Bivalent - protects against 2 strains HPV16 & HPV18 Gardasil - quadrivalent vaccine - protects against 4 strains HPV16, HPV18, HPV6 & HPV11 Gardasil 9 - 2021-22 vaccine programme - same as Gardasil + also HPV31, HPV33, HPV45, HPV52
49
Immunisation schedule for HPV vaccine
* best effectiveness, vaccine must be given before the patient becomes sexually active * usually 2 doses of the vaccine given 6 mths apart * U15yrs 15: - 1st dose of 0.5ml of HPV vaccine - 2nd dose of 0.5 ml 6mths (up to 24mths) after 1st dose * O15yrs - 3-dose schedule given at 0, 1, and 4–6mths
50
cause of genital warts
viral cause: HPV ondylomata acuminata
51
transmission of genital warts
* direct skin to skin contact with a person who has clinical/subclinical HPV, or contact with genital secretions * most common - sexual contact, but also peri-natally and from hand warts * oro-genital transmission is also possible * can also occur from contact with contaminated surfaces/objects * auto-inoculation from one site to another common
52
Genital warts - symptoms
* Often asymptomatic * Can be single, or multiple, and tend to occur in areas of high friction * Lesions may be disfiguring or embarrassing * Possible itching, bleeding or dyspareunia * Present as soft cauliflower-like growths of varying size * Less commonly - flat, plaque-like or pigmented * Colour can vary from whitish to flesh-coloured to hyperpigmented to erythematous * Usually less than 10 mm in diameter
53
Genital warts - Treatment options
1. No Tx - 30% warts disappear spontaneously within 6mths, not always indicated 2. Self applied Tx - Podophyllotoxin 0.5% solution or 0.15% cream (Warticon) - Imiquimod 5% cream (Aldara) - Sinecatechins 10% ointment (Catephen) 3. Abrasive methods - cryotherapy - excision - electrocautery 4. Specialist application - trichloroacetic acid (TCA) 80-90% solution
54
Genital warts – Treatment choice
* All Tx have significant failure and relapse rates * Choice of Tx is dependent upon the: - type of warts - non-keratinised or keratinised - no. & volume of warts - response to previous Tx - site of lesions
55
Genital warts - advice
* conflicting info on condom use * HPV persists after clinical clearance of warts for very variable lengths of time * Psychological distress is common - referral for counselling * 20% have concurrent STIs * Current partners and partners in the previous 6mths should be assessed * Advice about smoking cessation should be given - better Tx response
56
Genital warts – follow up
* Review after completion of Tx * Change treatment if: - intolerant of the current Tx - < 50% response to it by 4–5 weeks (8-12 weeks for imiquimod) * Follow up 3mths after Tx if concern re recurrences (timeframe recurrence is likely) * More frequent follow up if immunocompromised
57
Viral cause or herpes simplex
herpes simplex virus (HSV) 1 or HSV-2
58
Transmission of herpes simplex
* Infectious secretions on oral (HSV-1) , genital or anal mucosal surfaces (HSV-2) * Contact with lesions from other anatomical sites * Most HSV infections (80%) are transmitted by people who are unaware they're infected
59
HSV - symptoms 1st episode
* Multiple painful blisters * Lesions are usually bilateral & develop 4–7 days after exposure to HSV infection * If symptomatic with lesions - report headache, fever, malaise, dysuria, or tender inguinal lymphadenopathy * Other symptoms include - vaginal/urethral discharge, local oedema * Tingling/neuropathic pain in the genital area, lower back, buttocks or legs * Lasts up to 20 days
60
HSV - symptoms recurrent genital herpes
* Usually occurs in the same area and may be preceded by localized prodromal tingling and burning Sx 48hrs before the appearance of lesions * Often less severe and last from 6-48hrs * Systemic symptoms, fever & malaise are less common * Lesions crust and heal in around 10 days
61
triggers for HSVreactivation
* Local trauma (sexual intercourse or surgery) * UV light * Physical illness, immunosuppression * Smoking * Drinking alcohol * Tight clothing, nylon or Lycra underwear * Stress
62
HSV – Tx 1st episode
ORAL ANTIVIRALS: * start within 5 days of the start of the episode/while new lesions are forming for people with a first episode * BASHH guidelines - first-line treatment should be five days of: - Aciclovir 400 mg TDS or - Valaciclovir 500 mg BD * Self care measures ** only helps with the episode
63
HSV – Tx recurrent episodes
* Supportive measures alone * Antiviral therapy as required * Suppressive therapy Episodic Tx: * BASHH advises short courses as options for 1st line therapy: - Aciclovir 800 mg TDS for 2 days - Famciclovir 1 g BD for 1 day - Valaciclovir 500 mg BD for 3 days
64
Suppressive Tx for HSV
* Often indicated if >6 attacks per year. * Usual treatment: - Aciclovir 400 mg BD (or 200 mg QDS) - Famciclovir 250 mg BD - Valaciclovir 500 mg OD * The suppressive effect takes 5 days of therapy to establish * Discontinue after 12mths to reassess attack frequency (duration = 6-12mths) * Suppressive Tx also reduces the risk of asymptomatic shedding
65
Supportive management of HSV Tx
* Saline bathing * Oral painkillers * Topical anaesthetics * abstain until lesions cleared * Pain on micturition (urination) - vaseline - micturition in a bath can help prevent urinary retention - inc fluid intake to dilute urine
66
Supportive management of HSV Tx
* Saline bathing (prevent 2 infection) * Oral painkillers * Topical anaesthetics * abstain until lesions cleared * Pain on micturition (urination) - vaseline - micturition in a bath can help prevent urinary retention - inc fluid intake to dilute urine
67
HSV – follow up
* Advise to refrain from intercourse when have active lesions * Disclosure in relationships should be advised * No cure for genital herpes
