The kidneys and the urinary tract are a common source of infection in children of all ages, especially infants and young children. The main risk factors for sequelae after urinary tract infections (UTI) are congenital anomalies of the kidney and urinary tract (CAKUT) and bladder-bowel dysfunction. UTI should be considered in every child with fever without a source. The differentiation between...

Covid-19 in children, pregnancy and neonates: a review of epidemiologic and clinical features

Zimmermann, Petra ; Curtis , Nigel

In: The Pediatric Infectious Disease Journal, 2020, vol. 39, no. 6, p. 469–477

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has spread rapidly across the globe. In contrast to initial reports, recent studies suggest that children are just as likely as adults to become infected with the virus but have fewer symptoms and less severe disease. In this review, we summarize the epidemiologic and clinical features of children infected with...

Breast milk microbiota: A review of the factors that influence composition

Zimmermann, Petra ; Curtis, Nigel

In: Journal of Infection, 2020, vol. 81, no. 1, p. 17–47

Breastfeeding is associated with considerable health benefits for infants. Aside from essential nutrients, immune cells and bioactive components, breast milk also contains a diverse range of microbes, which are important for maintaining mammary and infant health. In this review, we summarise studies that have investigated the composition of the breast milk microbiota and factors that might...

Study protocol for the ABERRANT study: antibiotic-induced disruption of the maternal and infant microbiome and adverse health outcomes — a prospective cohort study among children born at term

Volery, Maryse ; Scherz, Valentin ; Jakob, William ; Bandeira, Diane ; Deggim-Messmer, Vanessa ; Lauber-Biason, Anna ; Wildhaber, Johannes ; Falquet, Laurent ; Curtis, Nigel ; Zimmermann, Petra

In: BMJ Open, 2020, vol. 10, no. 6, p. e036275

Introduction: There is compositional overlap between the maternal intestinal microbiome, the breast milk microbiome and the infant oral and intestinal microbiome. Antibiotics cause profound changes in the microbiome. However, the effect of intrapartum and early-life antibiotics on the maternal intestinal and breast milk microbiome, and the infant oral and intestinal microbiome, and whether...

Coronavirus infections in children including covid-19: an overview of the epidemiology, clinical features, diagnosis, treatment and prevention options in children

Petra, Zimmermann ; Nigel, Curtis

In: The Pediatric Infectious Disease Journal, 2020, vol. 39, no. 5, p. 355–368

Coronaviruses (CoVs) are a large family of enveloped, single-stranded, zoonotic RNA viruses. Four CoVs commonly circulate among humans: HCoV2-229E, -HKU1, -NL63 and -OC43. However, CoVs can rapidly mutate and recombine leading to novel CoVs that can spread from animals to humans. The novel CoVs severe acute respiratory syndrome coronavirus (SARS-CoV) emerged in 2002 and Middle East...

The immunomodulatory effects of macrolides - a systematic review of the underlying mechanisms

Zimmermann, Petra ; Ziesenitz, Victoria C. ; Curtis, Nigel ; Ritz, Nicole

In: Frontiers in Immunology, 2018, vol. 9, p. -

The mechanisms underlying the non-antimicrobial immunomodulatory properties of macrolides are not well understood.Objectives: To systematically review the evidence for the immunomodulatory properties of macrolides in humans and to describe the underlying mechanism and extent of their influence on the innate and adaptive immune system.Methods: A systematic literature search was done in MEDLINE...

Infected cephalhaematoma in a five-week-old infant - case report and review of the literature

Zimmermann, Petra ; Duppenthaler, Andrea

In: BMC Infectious Diseases, 2016, vol. 16, no. 1, p. 636

A cephalhaematoma is usually a benign condition which resolves spontaneously. Nevertheless, there is a small risk of primary or secondary infection and diagnosis of this condition is challenging. The purpose of this article is to summarise risk factors, clinical criteria, pathogenesis, appropriate investigations and treatment methods for infected cephalhaematomas in infants.Case presentation:...

The effect of maternal immunisation during pregnancy on infant vaccine responses

Zimmermann, Petra ; Perrett, Kirsten P. ; Messina, Nicole L. ; Donatha, Susan ; Ritz, Nicole ; Klis, Fiona R. M. van der ; Curtis, Nigel

In: EClinicalMedicine, 2019, vol. 13, p. 21–30

Immunisation during pregnancy to protect infants against tetanus, pertussis and influenza is recommended in many countries. However, maternal antibodies can interfere with infant vaccine responses. We investigated the effect of antenatal diphtheria-tetanus-acellular pertussis (dTpa) and trivalent inactivated influenza (TIV) immunisation on specific and heterologous antibody responses to...
