RESUMO
Candida lusitaniae fungemia is a serious infection that is rarely reported in children. The aim of this study is to describe a case series of C. lusitaniae fungemia and review previous publications regarding this rare pathogen. This is a multicenter case series of children diagnosed with C. lusitaniae fungemia. A total of 18 cases that occurred over a 15-year period in five tertiary hospitals were included. Additionally, a review of the literature regarding C. lusitaniae fungemia in children was performed. A total of 18 cases were enrolled; 11/18 (61%) were males, with a mean age of 2.3 years. All patients had severe underlying diseases and risk factors for opportunistic infection, most commonly prematurity and malignancies. More than one-third of cases occurred during the last 2 years of the study period. All isolates were susceptible to all tested antifungals. The survival rate following the acute infection was 94%, whereas the survival rate of 14 previously published cases was 71%, with the most common underlying diseases being CGD and malignancies. Candida lusitaniae fungemia is not a common event in the pediatric population, occurring exclusively in children with severe underlying diseases and significant risk factors. This cohort revealed better clinical outcomes than previously reported. All tested isolates were susceptible to all antifungal agents; variability in susceptibility as previously reported was not found in this study. The allegedly higher rate of infection in recent years is in need of further investigation in larger prospective studies in order to conclude if a real trend is at play.
Candida lusitaniae fungemia is a serious infection rarely reported in children. This cohort revealed better clinical outcomes than previously reported. All tested isolates were susceptible to all antifungal agents. The higher rate of infection in recent years is in need of further investigation.

Citrin deficiency is an autosomal recessive disorder associated with SLC25A13 gene pathogenic variants, with more than a hundred known at present. It manifests in neonates as failure to thrive and acute liver insufficiency. We herein describe a case of a 4-week-old infant who presented with insufficient weight gain and liver failure accompanied by hyperammonemia. She was diagnosed with Citrin deficiency after a thorough biochemical and molecular analysis including amino acid profile, DNA sequencing of genes of interest and RNA splice site evaluation, to reveal a yet unknown damaging variant of the SLC25A13 gene.

BACKGROUND: Q fever is a zoonosis caused by the bacterium Coxiella burnetii (C. burnetii) with a worldwide distribution. Our aim was to assess the epidemiology, clinical manifestations and treatment regimens of chronic Q fever infections in Israeli children during the past 25 years. METHODS: Cases were collected from the national Q fever reference laboratory database. Demographic, epidemiologic and clinical data were reviewed using a structured questionnaire sent to the referring physician. Cases were defined according to the new Dutch Consensus Guidelines. RESULTS: A total of 16 children originating from all regions of the country were found positive for chronic Q fever infections. The most common infection site was bone or joint (8/16, 50%), all in previously healthy children. Endovascular infections were found in 5 children (31%), all with an antecedent cardiac graft insertion. According to the new Consensus Guidelines, 9 children (56%) had a proven infection, 3 (19%) a probable infection and 4 (25%) a possible chronic Q fever infection. Almost all cases were treated with a long-term antibiotic regimen, often necessitating a change in medication because of persistent or rising titers. CONCLUSIONS: Although pediatric chronic Q fever infections are rare, incidence has been rising. The most common infection site was bone or joint. A high index of suspicion is necessary, even in cases of previously healthy children without a possible exposure history. Use of the relatively new diagnostic tools in combination with serologic methods is helpful in diagnosing proven cases. There is no consensus as to the selection or duration of antibiotic treatment.
