Most likely cause of deathInfection with GBS and E coliDegree of maceration indicated baby died in
33rd week of gestationBaby was not SGA

Several days post delivery…Presented to hospital with acutely sore right
hipRadiology was suggestive of a small joint
effusion Indicating transient synovitisUltrasound guided aspiration of the right hip
donePain settledAspiration was culture negative

3 days after initial aspirationHip pain returned worse than beforeArthroscopic joint aspiration and washout
was doneThick straw colored exudative fluid was
aspiratedThis aspirate grew GBS sensitive to
amoxycillinShe received 2 weeks of IV antibiotics
followed by 4 weeks of orals and recovered well without further complications

A rare case of GBS associated septic arthritis following an FDIU caused by the same organism in a young immuno-competent
woman.

GBS… gram positive cocci in chains
![Page 13: Tasveer Singh O&G Registrar Blacktown Hospital. Meet Jane Doe… A 34 year old woman first pregnancy booked in with an Obstetrician at 9 weeks gestation](https://reader036.vdocuments.us/reader036/viewer/2022062407/56649dfe5503460f94ae6145/html5/thumbnails/13.jpg)
DiscussionRole of GBS in Obstetric practice and neonatal
sepsis is well documented in literature Prophylactic IV antibiotics in labour is
protocol in every obstetric hospital3 to 8 per 1000 live births result in stillbirths
in developed countriesGBS has been linked to 4-10% of stillbirths
across in Europe and USA The most likely spread is by ascending route
across the membranes
![Page 14: Tasveer Singh O&G Registrar Blacktown Hospital. Meet Jane Doe… A 34 year old woman first pregnancy booked in with an Obstetrician at 9 weeks gestation](https://reader036.vdocuments.us/reader036/viewer/2022062407/56649dfe5503460f94ae6145/html5/thumbnails/14.jpg)
GBS rarely causes invasive infection, however haematogenous and trans-fallopian routes have been reported as well.
Gibbs & Roberts, Boston, 2007 foetal death in-utero was due to invasive GBS
sepsis of the foetus, in a woman with intact membranes who
presented in labour at term with an FDIU. diagnosis also made from autopsy and cultures
![Page 15: Tasveer Singh O&G Registrar Blacktown Hospital. Meet Jane Doe… A 34 year old woman first pregnancy booked in with an Obstetrician at 9 weeks gestation](https://reader036.vdocuments.us/reader036/viewer/2022062407/56649dfe5503460f94ae6145/html5/thumbnails/15.jpg)
Septic arthritis is a orthopaedic emergency and GBS is isolated as the cause in 10-20% of cases
Although uncommon, if misdiagnosed can severely damage the involved joint
GBS seen usually in the elderly population and the immunocompromised.
Few reported cases of septic arthritis in young women who have suffered an adverse pregnancy outcome or instrumentation of the uterus.

Imam et al in 2012 reported a case of a Sri Lankan housewife who developed septic Arthritis of the shoulder and Sacroiliac joints from GBS only 12 hours post-partum.
McKenna & O’ Brien reported sacroiliitis from GBS following mid-trimester dilation &curettage in a 37 year old undergoing medical termination of pregnancy in the USA

ConclusionGBS is a commonly encountered commensal
of the female genital tractInvasive infection from GBS is rare, but few
cases documented leading to adverse pregnancy outcome
GBS not a common cause of septic arthritis Handful of cases in literature of invasive
infection from GBS during pregnancy causing FDIU and septic arthritis
