IUCD and actinomyces
Last edited 07/2019
- Actinomyces are part of the normal vaginal flora - however Actinomyces is rarely detected in the absence of intrauterine contraceptive devices (IUCDs) (1)
- if actinomyces-like organisms (ALOs) and intrauterine contraceptive (IUC)
device
- If ALOs are identified and the woman presents with symptoms of pelvic
pain, then removal of IUC may be considered. Treatment involves high-does
antibiotics for at least 8 weeks and health professionals should consult
with a microbiologist. Other more common causes of pain (including STIs)
should be excluded
- has been suggested that asymptomatic women with positive ALOs on
a cervical smear are more likely to be colonised by ALOs than infected,
with the IUD potentially providing a good surface for the development
of biofilm in vivo
- there is no need to remove IUC in asymptomatic women with ALOs
- for women who require a replacement device but have ALOs identified
there is some evidence to suggest that immediate reinsertion or a
short delay of 3-5 days is safe
- insertion or reinsertion of an intrauterine method can be carried
out in asymptomatic women with ALOs (3)
- there is no need to remove IUC in asymptomatic women with ALOs
(3)
- if asymptomatic then (5):
- coil does not need to be removed and antibiotics are not required
- patient should have an abdominal and pelvic examination
- patient should be warned of the small possibility of developing pelvic actinomycosis and advised to return should she develop symptoms
- family planning follow-up should be arranged every six months and should include enquiry regarding new symptoms and a pelvic examination
- repeat cytology is not required unless the smear was graded inadequate/abnormal i
- f the asymptomatic patient wishes the device to be removed or it is due for removal then it need not be sent for culture.
- if asymptomatic then (5):
- has been suggested that asymptomatic women with positive ALOs on
a cervical smear are more likely to be colonised by ALOs than infected,
with the IUD potentially providing a good surface for the development
of biofilm in vivo
- If ALOs are identified and the woman presents with symptoms of pelvic
pain, then removal of IUC may be considered. Treatment involves high-does
antibiotics for at least 8 weeks and health professionals should consult

should be excluded
Notes:
- actinomyces israelii is a commensal of the female genital tract.
- Actinomyces-like organisms (ALOs) have been identified in women with and without IUC - although it is acknowledged that the level is thought to be low and that actinomycosis is rare
- role of ALOs in infection in women using IUC is unclear
