Cervicitis: a prospective observational study of empiric azithromycin treatment in women with cervicitis and non-specific cervicitis.

Treatment with 1 G azithromycin was observed prospectively in 130 women with cervicitis (>30 polymorphonuclear leucocytes/high-powered field) enrolled in a cervicitis aetiology study of 558 women at three sexually transmitted infection clinics in Sydney, Australia. Two overlapping groups of women with cervicitis were considered: 'cervicitis group 1' (n = 116) excluded women with Trichomonas vaginalis and a subgroup of this, 'cervicitis group 2' (non-specific cervicitis) (n = 96) further excluded women with Neisseria gonorrhoea, Chlamydia trachomatis and Mycoplasma genitalium at enrolment. Testing for Chlamydia trachomatis, Mycoplasma genitalium and Trichomonas vaginalis was by PCR and Neisseria gonorrhoea by PCR and culture. Treatment outcomes were cervicitis or vaginal symptoms at follow-up. Effect on cervicitis at follow-up was also assessed after additional reported partner treatment. In 'cervicitis group 1' where prevalence of Mycoplasma genitalium and/or Chlamydia trachomatis was 23/116 (19.8%), azithromycin reduced cervicitis at follow-up (RR = 0.62 (95% CI 0.39-0.97) p = 0.035), but there was no significant effect in non-specific cervicitis ('cervicitis group 2') (RR = 0.60 (95% CI 0.35-1.01) p = 0.056). Empiric treatment did not reduce vaginal symptoms at follow-up in either group. No effect of empiric partner treatment was seen. The conclusion was that empiric azithromycin treatment of cervicitis reduces cervicitis at follow-up in populations with high prevalence of Chlamydia trachomatis and/or Mycoplasma genitalium. There are no benefits of empiric azithromycin for non-specific cervicitis or empiric partner treatment.

Congenital cytomegalovirus infection in pregnancy: a review of prevalence, clinical features, diagnosis and prevention.

Human cytomegalovirus (CMV) is under-recognised, despite being the leading infectious cause of congenital malformation, affecting ~0.3% of Australian live births. Approximately 11% of infants born with congenital CMV infection are symptomatic, resulting in clinical manifestations, including jaundice, hepatosplenomegaly, petechiae, microcephaly, intrauterine growth restriction and death. Congenital CMV infection may cause severe long-term sequelae, including progressive sensorineural hearing loss and developmental delay in 40-58% of symptomatic neonates, and ~14% of initially asymptomatic infected neonates. Up to 50% of maternal CMV infections have nonspecific clinical manifestations, and most remain undetected unless specific serological testing is undertaken. The combination of serology tests for CMV-specific IgM, IgG and IgG avidity provide improved distinction between primary and secondary maternal infections. In pregnancies with confirmed primary maternal CMV infection, amniocentesis with CMV-PCR performed on amniotic fluid, undertaken after 21-22 weeks gestation, may determine whether maternofetal virus transmission has occurred. Ultrasound and, to a lesser extent, magnetic resonance imaging are valuable tools to assess fetal structural and growth abnormalities, although the absence of fetal abnormalities does not exclude fetal damage. Diagnosis of congenital CMV infection at birth or in the first 3 weeks of an infant's life is crucial, as this should prompt interventions for prevention of delayed-onset hearing loss and neurodevelopmental delay in affected infants. Prevention strategies should also target mothers because increased awareness and hygiene measures may reduce maternal infection. Recognition of the importance of CMV in pregnancy and in neonates is increasingly needed, particularly as therapeutic and preventive interventions expand for this serious problem.

Cervicitis aetiology and case definition: a study in Australian women attending sexually transmitted infection clinics.

OBJECTIVES: Studies examining cervicitis aetiology and prevalence lack comparability due to varying criteria for cervicitis. We aimed to outline cervicitis associations and suggest a best case definition. METHODS: A cross-sectional study of 558 women at three sexually transmitted infection clinics in Sydney, Australia, 2006-2010, examined pathogen and behavioural associations of cervicitis using three cervicitis definitions: 'microscopy' (>30 pmnl/hpf (polymorphonuclear leucocytes per high-powered field on cervical Gram stain)), 'cervical discharge' (yellow and/or mucopurulent cervical discharge) or 'micro+cervical discharge' (combined 'microscopy' and 'cervical discharge'). RESULTS: Chlamydia trachomatis (CT), Mycoplasma genitalium (MG), Trichomonas vaginalis (TV) and Neisseria gonorrhoeae (NG) had the strongest associations with cervicitis definitions 'micro+cervical discharge': CT adjusted prevalence ratio (APR)=2.13 (95% CI 1.38 to 3.30) p=0.0006, MG APR=2.21 (1.33 to 3.69) p=0.002, TV APR=2.37 (1.44 to 3.90) p=0.0007 NG PR=4.42 (3.79 to 5.15) p<0.0001 and 'cervical discharge': CT APR=1.90 (1.25 to 2.89) p=0.003, MG APR=1.93 (1.17 to 3.19) p=0.011, TV APR=2.02 (1.24 to 3.31) p=0.005 NG PR=3.88 (3.36 to 4.48) p<0.0001. Condom use for vaginal sex 'always/sometimes' reduced cervicitis risk: ('micro+cervical discharge') APR=0.69 (0.51 to 0.93) p=0.016. Combined population attributable risk % (PAR%) of these four pathogens was only 18.0% with a protective PAR% of condoms of 25.7%. Exposures not associated with cervicitis included bacterial vaginosis, Mycoplasma hominis, Ureaplasma urealyticum, herpes simplex virus 1&2, cytomegalovirus, Candida, age, smoking and hormonal contraception. CONCLUSIONS: Cervicitis was associated with CT, MG, TV and NG with combined PAR% of these pathogens only 18% in this setting, suggesting other factors are involved. Condoms significantly reduced cervicitis risk. Cervicitis definitions with best clinical utility and pathogen prediction were 'cervical discharge' and 'micro+cervical discharge'.
