SOMANZ (Society of Obstetric Medicine Australia and New Zealand) has written a guideline to provide evidence-based guidance for the investigation and care of women with sepsis in pregnancy or the postpartum period.

The guideline is evidence-based and incorporates recent changes in the definition of sepsis. The etiology, investigation and treatment of bacterial, viral and non-infective causes of sepsis are discussed.

Obstetric considerations relevant to anaesthetic and intensive care treatment in sepsis are also addressed. A multi-disciplinary group of clinicians with experience in all aspects of the care of pregnant women have contributed to the development of the guidelines.

This is an executive summary of the guidelines.

La infección en el recién nacido puede adquirirse a través del canal del parto por colonización materna, como la infección neonatal precoz por Streptococcus agalactiae, o por adquisición a través de la placenta, líquido amniótico o productos del parto.

Tras el parto, el recién nacido que precisa ingreso hospitalario puede adquirir infecciones nosocomiales durante su estancia y de forma excepcional, a través de la lactancia, por mastitis infecciosa o por incorrecta manipulación de la leche materna propia o donada de bancos de leche, lo que no obliga a suspender la lactancia en la mayoría de las ocasiones pero sí a establecer un tratamiento.

Por los motivos expuestos es necesario establecer un correcto diagnóstico microbiológico de las infecciones perinatales, especialmente relevantes en el recién nacido pretérmino de bajo o muy bajo peso con una elevada mortalidad.

Szychowski, Ph.D., Kim Boggess, M.D., George Saade, M.D., Sherri Longo, M.D., Erin Clark, M.D., Sean Esplin, M.D., Kirsten Cleary, M.D., Ron Wapner, M.D., Kellett Letson, M.D., Michelle Owens, M.D., Adi Abramovici, M.D., Namasivayam Ambalavanan, M.D., Gary Cutter, Ph.D., and William Andrews, M.D., Ph.D., for the C/SOAP Trial Consortium*


The addition of azithromycin to standard regimens for antibiotic prophylaxis before cesarean delivery may further reduce the rate of postoperative infection. We evaluated the benefits and safety of azithromycin-based extended-spectrum prophylaxis in women undergoing nonelective cesarean section.


In this trial conducted at 14 centers in the United States, we studied 2013 women who had a singleton pregnancy with a gestation of 24 weeks or more and who were undergoing cesarean delivery during labor or after membrane rupture. We randomly assigned 1019 to receive 500 mg of intravenous azithromycin and 994 to receive placebo. All the women were also scheduled to receive standard antibiotic prophylaxis. The primary outcome was a composite of endometritis, wound infection, or other infection occurring within 6 weeks.


The primary outcome occurred in 62 women (6.1%) who received azithromycin and in 119 (12.0%) who received placebo (relative risk, 0.51; 95% confidence interval [CI], 0.38 to 0.68; P<0.001). There were significant differences between the azithromycin group and the placebo group in rates of endometritis (3.8% vs. 6.1%, P=0.02), wound infection (2.4% vs. 6.6%, P<0.001), and serious maternal adverse events (1.5% vs. 2.9%, P=0.03). There was no significant between-group difference in a secondary neonatal composite outcome that included neonatal death and serious neonatal complications (14.3% vs. 13.6%, P=0.63).


Among women undergoing nonelective cesarean delivery who were all receiving standard antibiotic prophylaxis, extended-spectrum prophylaxis with adjunctive azithromycin was more effective than placebo in reducing the risk of postoperative infection.

Antibiotic prophylaxis for cesarean delivery — when broader is better.

Weinstein RA and Boyer KM

Approximately 4 million babies are born each year in the United States. Of these infants, about a third are delivered by cesarean section. One of the many concerns about cesarean deliveries is the high risk of maternal infectious complications, which are 5 to 10 times more frequent than with vaginal deliveries.1 During cesarean delivery, the endometrial cavity and operative field may be seeded with pathogens, carried from the birth canal or the skin, that put mothers at risk for endometritis (incidence without prophylaxis, 4 to 18%) and of surgical-site infections (incidence without prophylaxis, 7 to 10%).2 To reduce these risks, prophylactic administration of an intravenous periprocedural antibiotic, usually cefazolin, is routinely recommended. Such an infusion reduces these rates by about half.3 Stringent adherence to infection-control protocols and broader antibiotic regimens might yield further reductions……

Se diseñó un estudio prospectivo para evaluar las características del nuevo kit CT OligoGen en comparación con el test cobas 4800 para la detección de Chlamydia trachomatis.


Se analizaron una serie de muestras que incluían orinas (n = 212), exudados endocervicales (n = 167), rectales (n = 53), faríngeos (n = 7) y uretrales (n = 3). Estas muestras provenían de un centro de infecciones de transmisión sexual (Sevilla) y pertenecían a 261 hombres y 181 mujeres. Los resultados discordantes se reanalizaron y revisaron historias clínicas y otras pruebas para resolverlas.


Los valores de sensibilidad, especificidad, valor predictivo positivo (VPP) y negativo (VPN) y valor kappa para el kit CT OligoGen fue 98,5%, 100%, 100%, 95,4% and 0,97, respectivamente.


Este nuevo kit tuvo una alta sensibilidad, especificidad, VPP y VPN para la detección de C. trachomatis, por lo que esta evaluación confirma su utilidad y fiabilidad.

Urogenital Chlamydia trachomatis infection remains prevalent and causes substantial reproductive morbidity. Recent studies have raised concern about the efficacy of azithromycin for the treatment of chlamydia infection.


We conducted a randomized trial comparing oral azithromycin with doxycycline for the treatment of urogenital chlamydia infection among adolescents in youth correctional facilities, to evaluate the noninferiority of azithromycin (1 g in one dose) to doxycycline (100 mg twice daily for 7 days). The treatment was directly observed. The primary end point was treatment failure at 28 days after treatment initiation, with treatment failure determined on the basis of nucleic acid amplification testing, sexual history, and outer membrane protein A (OmpA) genotyping of C. trachomatis strains.


Among the 567 participants enrolled, 284 were randomly assigned to receive azithromycin, and 283 were randomly assigned to receive doxycycline. A total of 155 participants in each treatment group (65% male) made up the per-protocol population. There were no treatment failures in the doxycycline group. In the azithromycin group, treatment failure occurred in 5 participants (3.2%; 95% confidence interval, 0.4 to 7.4%). The observed difference in failure rates between the treatment groups was 3.2 percentage points, with an upper boundary of the 90% confidence interval of 5.9 percentage points, which exceeded the prespecified absolute 5-percentage-point cutoff for establishing the noninferiority of azithromycin.


In the context of a closed population receiving directly observed treatment for urogenital chlamydia infection, the efficacy of azithromycin was 97%, and the efficacy of doxycycline was 100%. The noninferiority of azithromycin was not established in this setting. (Funded by the National Institute of Allergy and Infectious Diseases; number, NCT00980148.)




Treatment for Chlamydia Infection — Doxycycline versus Azithromycin

Thomas C. Quinn, M.D., and Charlotte A. Gaydos, Dr.P.H.

From the Division of Intramural Research, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Bethesda (T.C.Q.), and the Division of Infectious Diseases, Johns Hopkins University School of Medicine, Baltimore (T.C.Q., C.A.G.) — both in Maryland.

Chlamydia trachomatis infection is the most common bacterial sexually transmitted infection in the United States. In 2013, a total of 1.4 million cases were reported, and 3 million persons were estimated to be infected. Worldwide, 131 million persons are estimated to be infected with C. trachomatis. Untreated infections in women can result in pelvic inflammatory disease, infertility, ectopic pregnancy, and chronic pelvic pain. In men, the infection can be associated with urethritis, epididymitis, and, in men who have sex with men, proctitis. The Centers for Disease Control and Prevention (CDC) recommends that all sexually active women younger than 25 years of age undergo annual chlamydia screening.1 However, less than half of women 16 to 24 years of age who are enrolled in medical care programs were screened in 2013…..
