Q

Gonnorhea

A

N.Gonnorhea - Encapsulated and therefore resitant to phagocyosis

Large ASx resevoir - Pharynx/rectal/cervical

Disseminated dx - in females = penicillin sensitive

Opthalmoplegia neonartu - Systemix Abx and Eye drops

> 10% = resistant to Penicillin + quinolones

–> Tx = CEPHLASPORIN - IM CEFTRAXONE + PO azithromycin

Q

Syphillis

A

Treponem Pallidum

Transmission: SExual > Blood borne.

Diagnosis:
1) Serology = 2 x specific Ag test (EIA or TPHA) + Quantitive PCR

2) Dark ground microscopy - of tissue from Chancre or rash
3) Treponem PCR - Early syphillis Ulcer

In secondary syphillis - haem spread:

  • Mucocutaneous - non-itchy rash
  • LN
  • Neuro - CN palsy/ Meningitis
  • Occular - ant. uveitis
  • GI - Hepatitis or proctitis
  • Rheu - polyarthritis

Tx = Benzylpenicillin or Tetracycline

REINFECTION ??? –> use rapid plasma reagin - all others stay +ve despite txx

Q

Chlamydia

A

Most common bacterial UTI –> Non-gonnocal urethritis.

Complications:

  • Female - PID.
  • Male - prostatitis/epididymitis
  • Babies - Neonatal conjunctivitis or pneumonitis - Systemic Erythromycin

In UK serovaa D + K most common

Other Complications:

  • Trachoma - corneal scarring = Serova A/B/C
  • Lymphogranuloma venerum = rectal inflamm + prostatitis - in MSM - Serova L1/L2/L3

Inx - NAATs

Q

Risk factors for Aids

A

Most common transmission is M+F > MSM > Blood > IVDU

HIV 1 - most common worldwide
HIV2 - Most common in West Africa

RF:

  • Seroconversion or adv disease
  • concurrent STI
  • Concurrent Hep C
  • High Viral Load

Maternal –> Fetal RF = BREASTFEEDING reduce transmission by:

  • Antiretroviral before 3rd trimester
  • Avoid Breastfeeding
  • If detect VL @ 36 weeks –> C-section

Q

HIV Mechanism

A

HIV follows CD4 cells: T-helper, B cells, Macrophages and CNS cells

HIV –> Decreased CD4 and therefore a low CD4:CD8

Markers assoc w/ Progression:

  • Low CD4
  • High Viral Load

Seroconversion:

  • up to 3/12
  • General unwekk sx, can ave meningo-encephalitis or arthropathy
  • Can’t detect HIV antibody during this time
  • Can detect HIV p24 Ag or HIV-1 (at 1 month)

Q

HIV/ AIDS Tx

A

HAART = 2x NNRTI + (NRTI or PI)

IL-2 can be used to icrease CD4 # if good supression of HIV but poor CD4 count

If Fx respond to Tx –> Salvage therapy = Add Enfuvirtide

Monitoring:

  • Clinical assess
  • CD4
  • Viral Load
  • Renal/Hepatic fn
  • Cholesterol/BGL
  • Lactate

If Viral Load high on 2x ocassions –> Test for Viral Resistance
