[Streptococcus group B and pregnancy: the therapeutic role of topical intravaginal clindamycin].
OBJECTIVE
To evaluate the clinical and therapeutic efficacy of 2% clindamycin vaginal cream in pregnant women heavily colonized with group B streptococci (GBS).


METHODS
A prospective, clinical trial in which carriers of group B streptococci were randomized to receive topical intravaginal clindamycin or oral amoxicillin.


METHODS
We randomized 105 pregnant women: 55 received 2% clindamycin vaginal cream (100 mg/day for 7 days) and 50 oral amoxicillin (2 g/day for 7 days).


METHODS
Patients were treated during pregnancy, none of them received intrapartum chemoprophylaxis. On the other hand, all the neonates, within 24 hours from delivery, were studied from the microbiological point of view, carrying out auricolar, nasal, oropharyngeal and umbilical cultures. RELIEFS: The eradication of the microorganism was evaluated by performing a vaginal culture after 6 weeks from the beginning of antibiotic therapy.


RESULTS
The eradication rate of the microorganism was significantly higher in women treated with topical clindamycin compared with the group receiving oral amoxicillin (71% versus 36%; p < 0.05). The neonatal outcome was similar in the two groups in terms of gestational age at delivery and mean birthweight. None of the neonates was admitted to the neonatal intensive care unit and no cases of neonatal sepsis were recorded.


CONCLUSIONS
From our experience we can conclude that, during pregnancy, a treatment with topical intravaginal clindamycin may be useful in the eradication of GBS.
