Prenatal ultrasound screening and pregnancy outcomes in HIV-positive women in Germany: results from a retrospective single-center study at the Charité-Universitätsmedizin Berlin.

OBJECTIVES: The aim of this study was to investigate the rate of Mother-to-child-transmission (MTCT) in women living with HIV (WLWH) in a tertiary care institution. Furthermore, we aimed to assess prenatal ultrasound screening for fetal anomalies and outcomes in high-risk pregnancies due to maternal HIV infection." METHODS: In this single-center study, retrospective data related to pregnancy and childbirth were collected from 420 WLWH. All data were evaluated descriptively. RESULTS: From January 2014 to December 2020, a total number of 420 pregnant WLWH delivered 428 newborns. 415 (98.8%) were receiving antiretroviral therapy (ART) and 88.8% had a viral load of < 50 cop/ml prior delivery. 46 (11%) of the newborns were born prematurely. Low birth weight < 2500 g occurred in 38 (9.1%) of the children. 219 (52.1%) caesarean sections (CS) were performed. The most frequent indication for an elective CS was a previous CS (70.2%). 8 severe malformations were detected using first and second trimester ultrasound. In one child, MTCT was detected postpartum, resulting in an HIV transmission rate of 0.2% in the presented cohort. CONCLUSIONS: The low rate of vertical HIV-transmission in our cohort of 0.2% is the result of interdisciplinary prenatal care and high experience of healthcare providers in treatment of WLWH. Despite high ART coverage and adherence, good maternal immune system and very low vertical HIV transmission rate, maternal HIV infection remains a challenge in obstetric care. First and second ultrasound screening should be a part of prenatal care for HIV-infected women and should also be offered to HIV-negative women. A reduction of the rate of unnecessary elective caesarean deliveries in WLWH is necessary to reduce complications in subsequent pregnancies.

Genotype-specific high-risk human papillomavirus infections and risk factors for cervical dysplasia in women with human immunodeficiency virus in Germany: results from a single-center cross-sectional study.

OBJECTIVE: Women living with HIV have an increased risk of human papillomavirus (HPV) infection and cervical cancer. Little is known about genotype-specific HPV prevalence, the impact of antiretroviral therapy, immunological status, and additional risk factors in women living with HIV in Germany. The goal of this study was to characterize the risk profile for cervical dysplasia in these women. METHODS: Patients with HIV infection presenting at Charité-Universitätsmedizin Berlin from October 2017 to September 2020 were included and underwent gynecological examination, colposcopy, cervical cytology and HPV genotype testing. HPV genotypes were stratified by carcinogenicity. Atypical squamous cells of undetermined significance or higher were considered abnormal cytology. Data were analyzed by SPSS software (version 26, 2019). A two-tailed p-value ≤0.05 was considered statistically significant. RESULTS: A total of 84 women were evaluated. The majority (95.2%) received antiretroviral therapy. Median CD4 cell count was 564 cells/µl (range 20-1969). 95.2% were previously screened for cervical cancer. High-risk HPV prevalence was 44%. High-high-risk HPV subtypes (16, 18, 31, 33, 45, 52, 58) were significantly associated with abnormal cytology (p<0.001). HPV16 was the most common genotype (23%), was significantly associated with abnormal cytology (p=0.002) and was the main risk factor for abnormal cytology (OR 8.55, 95% CI 2.15 to 34.13, p=0.002), followed by age <35 years (OR 4.96, 95% CI 1.23 to 19.61, p=0.033) and cigarette smoking (OR 3.944, 95% CI 0.98 to 15.88, p=0.053). CONCLUSIONS: Antiretroviral therapy and adherence to cervical cancer screening was high. High-high-risk HPV, especially HPV16, coincided with high incidence of cytological abnormalities. Women living with HIV in Germany have adequate immune status and are often pre-screened for cervical cancer, and therefore have a different risk profile for cervical dysplasia than in low-income or medium-income countries. Adapted screening programs should be defined.

Fetal growth restriction in a cohort of migrants in Germany.

BACKGROUND: Migrant women may have an increased risk of adverse birth outcomes. This study analyses the occurrence of low birth weight, preterm birth and intrauterine growth restriction / fetal growth restriction (IUGR/FGR) in pregnant migrants. METHOD: Cross-sectional study of 82 mother-child pairs of pregnant migrants attending medical care in Germany. RESULTS: The Median age was 27 years, 49% of patients were of oriental-asian ethnicity and median year of migration was 2015. At least one previous pregnancy was reported in 76% of patients, in 40% the delivery mode was caesarian section. Median gestational age was 39.7 weeks. Preterm birth occurred in 6.1% of pregnancies. Median gestational age for preterm birth was 32.3 weeks. Low birth weight (< 2500 g) occurred in 6.1%. Birth weights below the 10th percentile of birth weight for gestational age were observed in 8.5% of the total cohort. CONCLUSIONS: Compared to German data no increased occurrence of low birth weight, preterm birth or IUGR/FGR was found. We note that the rate of caesarian section births was higher than in the general population for reasons yet to be identified. The authors propose stratification according to migration status for the national documentation of birth outcomes in Germany.

Screening for Third-Generation Cephalosporin-Resistant Bacteria Reduces the Incidence on Late-Onset Sepsis and Antibiotic use in Neonates.

BACKGROUND: The extensive use of antibiotics is reflected by an increasing prevalence of infections with multidrug-resistant bacteria, including third-generation cephalosporin-resistant bacteria (3GCRB). For neonatal intensive care units screening and enhanced barrier precautions are recommended to control the spread of multidrug-resistant Gram-negative bacteria, while evidence for efficacy of barrier precautions remains scarce in a non-outbreak setting. OBJECTIVE: To determine the impact of a screening program for maternal 3GCRB colonization and the effects of contact precautions and cohort nursing, concerning the risk of neonatal late-onset sepsis (LOS) and antibiotic use rates (AURs). STUDY DESIGN: In a retrospective matched-pair cohort study, data of neonates exposed to maternal 3GCRB colonization were compared with findings in non-exposed neonates. RESULTS: Of 3,144 neonates admitted, 184 neonates born to 3GCRB-positive mothers were eligible. Among them, 37 (20%) became 3GCRB positive during hospital stay. 3GCRB-exposed infants had a lower rate of LOS (6.5 vs. 14.1%, p=0.03) and lower AURs in that time period compared to controls (mean 0.009 vs. 0.025, p=0.006). When started within the first 72h after birth, days of therapy with meropenem were significantly lower in non-exposed vs. 3GCRB-exposed infants (mean 0.13 vs. 0.42; p=0.002). No invasive infections with 3GCRB occurred. CONCLUSIONS: Neonates of 3GCRB-positive mothers do not have an increased a priori risk for invasive 3GCRB infection and may benefit from enhanced contact precautions measures. HINTERGRUND: Der zunehmende Einsatz von Antibiotika führt zu einem Anstieg von Infektionen mit multiresistenten Erregern wie z. B. Drittgeneration Cephalosporin-resistenten Bakterien (3GCRB). Empfehlungen zu Screening- und Kohortierungsmaßnahmen auf neonatologischen Intensivstationen zielen auf die Prävention von horizontaler Transmission und invasiven Infektionen ab. Für Nicht-Ausbruchssituationen ist die Evidenz für Hygienemaßnahmen und Screeningprogrammen unzureichend. ZIEL: Evaluation eines Screening für mütterliche 3GCRB-Besiedlung mit nachfolgender Isolation bzw. Kohortenpflege des Neugeborenen (NG) unter Bezug auf das Risiko einer Late-Onset-Sepsis (LOS) und die Anzahl der Antibiotika-Tage (AUR). STUDIENDESIGN: In einer retrospektiven Fall-Kontroll-Kohortenstudie wurden Daten von NG mit maternaler 3GCRB-Besiedelung im Vergleich zu einer Kontrollgruppe mit unauffälligem Screening analysiert. ERGEBNISSE: In einer Kohorte von 3144 NG fanden sich 184 NG von 3GCRB-besiedelten Müttern. Bei 37 (20%) wurde im Verlauf eine Besiedelung mit 3GCRB nachgewiesen. In der Gruppe der 3GCRB-exponierten NG kam es seltener zu einer LOS (6,5 vs. 14,1%, p=0,03). Zwischen dem 4. Lebenstag und der Entlassung hatten 3GCRB-exponierte NG eine niedrigere AUR (Mittelwert 0,009 vs. 0,025, p=0,006) als die Kontrollgruppe. Die Behandlungstage mit Meropenem (Start in den ersten 3 Lebenstagen), war in der Kontrollgruppe signifikant geringer als in der 3GCRB-exponierten Gruppe (Mittelwert 0,13 vs. 0,43 Tage; p=0,002). In beiden Gruppen trat keine invasive Infektion mit 3GCRB auf. SCHLUSSFOLGERUNG: Neugeborene, deren Mütter 3GCRB besiedelt sind, haben kein erhöhtes a priori Risiko für eine invasive Infektion mit 3GCRB Erregern und profitieren wahrscheinlich von erweiterten Kohortierungs- und Isolationsmaßnahmen.

Novel Insights in Fetal Cardiomyopathy due to in utero Herpes Simplex Virus Infection.

This is a case report of fatal cardiomyopathy in a fetus following maternal intrauterine infection with herpes simplex virus (HSV), despite the mother having no symptoms of an infection. The fetus showed signs of a disseminated infection affecting the heart, brain, lungs, liver, adrenal glands, and skin. HSV cardiomyopathy, characterized by vast necrosis, extensive calcifications, and inflammatory infiltration, was found to be the cause of intrauterine fetal death. To our knowledge, this is a unique report of an asymptomatic maternal nonprimary or recurrent HSV infection that induced a transmission of HSV resulting in extensive and fatal changes in the fetal heart.

The rationale for third trimester testing of vertical HIV transmission in neonates with CMV infection.

We report on a late-preterm neonate with severe congenital cytomegalovirus (CMV) infection, refractory to antiviral therapy with ganciclovir. Subsequent immune diagnostics led to the finding of HIV infection at day 69, even though the mother tested negative for HIV in early pregnancy. Thus, in congenital CMV infection, HIV testing should be performed to elucidate maternal HIV seroconversion during late pregnancy. Our case strongly supports third trimester screening of HIV infection acquired during pregnancy, yet recommended only for women with traditional risk factors for HIV or living in an area of high HIV prevalence.

Clinical, Laboratory, and Placental Findings in Perinatal Listeriosis.

Clinical, laboratory, and placental manifestations of perinatal listeriosis are highly variable. Herein, we retrospectively analyzed all patients treated for neonatal listeriosis at the Charité University Medical Center in Berlin, Germany, 1999-2013. A total of 16 cases were identified. In 14 patients listeriosis was confirmed in neonatal specimens, while in two only the placenta tested positive. Elevated C-reactive protein and/or interleukin-6 levels were only inconsistently found, while a marked white blood cell left shift was present in all infants, if available. All but one infant manifested symptoms on the first day of life. Most patients required respiratory support, while none developed meningoencephalitis as evidenced by clinical or cerebrospinal fluid findings. Two patients died, all other patients survived without sequelae. In conclusion, perinatal listeriosis is still associated with significant morbidity and mortality. Clinical and laboratory findings are highly heterogeneous, but extreme leukocyte left shift seems to be a common feature.

The mother as most important risk factor for colonization of very low birth weight (VLBW) infants with extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-E).

OBJECTIVES: This study aimed to determine the prevalence of and risk factors for colonization with extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-E) and methicillin-resistant Staphylococcus aureus (MRSA) in very low birth weight (VLBW; <1500 g) infants and their mothers. METHODS: This investigation was conducted in the perinatal centre at the Charité Berlin between May 2012 and June 2013. VLBW infants and their mothers were screened for colonization with ESBL-E and MRSA. Demographic and clinical data were obtained from the German nationwide surveillance system for nosocomial infections in VLBW infants (NEO-KISS) and used to perform univariate and multivariate analyses. RESULTS: Of 209 VLBW infants, 12 (5.7%) were colonized with ESBL-E. Eighteen of 209 (8.6%) ESBL-E-tested neonates were related to an ESBL-E-positive mother. Univariate analysis, strain typing and multivariate analysis (OR 7.4, 95% CI 2.1-26.7, P = 0.002) identified an ESBL-E-positive mother and maternal-neonatal transmission as a main source of colonization. The prevalence of MRSA was 2.3% (5 of 221) among VLBW infants. One of the 221 (0.5%) MRSA-tested neonates was related to an MRSA-positive mother. No risk factors for transmission of MRSA could be detected in this study. CONCLUSIONS: Our study demonstrated that maternal-neonatal transmission of ESBL-E from mother to child is an important risk factor for colonization of VLBW infants. As a consequence, routine ESBL-E screening of neonates and mothers should be considered as a means of reducing neonatal morbidity and mortality.

Breastfeeding is natural but not always easy: intervention for common medical problems of breastfeeding mothers - a review of the scientific evidence.

Natural processes do not always function perfectly. In breastfeeding, problems are encountered in up to 80% of mother-infant dyads. Altogether, in Western societies, the difficulties reduce the breastfeeding rate within the first months drastically. To deal with the problems of breastfeeding efficiently requires a profound understanding of its physiology, as well as of its psychological and social determinants. This review focuses on the current knowledge of breastfeeding physiology, only touching the psychosocial factors, which are included in the promotion strategies. Subsequently, it scrutinizes definitions, incidences, prevention, and treatment of breastfeeding problems faced most frequently by nursing mothers and their consultants. Not all measures used in counseling mothers and not all treatments for the most common medical problems withstand a careful evaluation on the basis of current scientific data. However, applying proven prevention strategies will significantly improve the well being of mothers and their infants, and may contribute to an affective attitude that increases the success, frequency, and duration of breastfeeding.

Not Recommended, But Done: Breastfeeding with HIV in Germany.

Breastfeeding (BF) in mothers living with HIV (MLWH) is still discussed controversially in resource-rich settings. In Germany, where formula feeding is recommended for MLWH single BF cases have been reported, but no systematic data collection and analysis are available so far. This study, titled HELENE, aims to fill this data gap. A questionnaire covering the course of BF was distributed by a graduate student visiting each study site. Information was collected from patient files and by personal communication with the health care provider. Primary study objectives were the duration of BF and the maternal antiretroviral treatment (ART). Fifteen treatment centers across Germany contributed a total of 42 BF cases, observed from May 2009 to July 2020. There was an increasing number of BF cases over time. The median duration of BF was 20 weeks varying from single BF of colostrum to 104 weeks. All BF women except one elite controller received ART: 39% non-nucleoside reverse transcriptase inhibitor-, 37% INSTI-, 29% protease inhibitor-based regimens; one woman was on maraviroc. Thirty-nine percent of the ART regimens included drugs that were not recommended by the German-Austrian pregnancy guidelines. Our findings highlight the diversity of BF cases in Germany in terms of duration, maternal ART, and monitoring. Since the number of BF cases is increasing, guidelines are obliged to implement more detailed recommendations on BF, the monitoring of BF mothers, and the follow-up of the infants. There is an urgent need for prospective national and European data collections to further improve HIV prevention of mother-to-child transmission (PMTCT) in the setting of BF.

The Charité cesarean birth: a family orientated approach of cesarean section.

OBJECTIVE: To evaluate the safety and patients delivery experience of the Charité Cesarean Birth (CCB), a modified cesarean section (CS). Parents are actively integrated in the delivery process by direct visualization of the birth, cutting the umbilical cord and early skin-to-skin contact (STS). METHODS: Women with an indication for a planned primary CS at term were included. Trial was conducted at the Charité University Hospital Berlin as a prospectively randomized controlled trial. Parameters of perinatal outcome for both mother and infant were assessed using modified Likert-Scales and a standardized questionnaire. Primary outcome measures were birth experience and satisfaction for parents. Parameters of breast feeding and consecutive problems. APGAR Scores, blood loss, perioperative complications were secondary outcome measures. RESULTS: Birth experiences were rated significantly higher in the CCB group compared to a classical caesarean section (p < 0.05). There were no significant differences between APGAR Scores, need for admission to an intensive care unit. Also perioperative blood loss and cardiovascular disorders did not differ between the two groups. Early STS was achieved in the 72% of the cases with higher rates of breast-feeding in the CCB group. CONCLUSIONS: The CCB leads to a significantly better birth experience. The procedure seems to be safe for both mother and infant. Patients become an active part of the CS by direct visualization of the birth and cutting the umbilical cord. The presented modification is a useful and safe option when a CS is medically indicated and necessary. It improves the breast-feeding and the early mother-infant interaction.
