ABSTRACT
The presence of active viral infections has an impact on the prognosis of patients undergoing hematopoietic stem cell transplantation (HSCT). Nevertheless, the number of reports of cytomegalovirus infection in patients with inborn errors of immunity (IEI) who undergo HSCT is relatively low. To analyze the effect of cytomegalovirus infection acquired prior to curative treatment on patient survival in 123 children with IEI. An observational and retrospective study was performed with patients younger than 18 years diagnosed with IEI who were candidates for HSCT, gene therapy, or thymus transplantation at five hospitals in Spain between 2008 and 2019. We included 123 children, 25 infected by cytomegalovirus prior to undergoing curative treatment (20.3%). At IEI diagnosis, 24 of the patients were already infected, 21 of whom had symptomatic cytomegalovirus disease (87%), while the other three patients developed disease before undergoing curative treatment. The patients with cytomegalovirus infection had higher mortality than those without (p = 0.006). Fourteen patients developed refractory cytomegalovirus infection (56%), all of whom died, while no patients with non-refractory infection died (p = 0.001) All deaths that occurred before curative treatment and three of the five after the treatment were attributed to cytomegalovirus. Patients with refractory cytomegalovirus disease had the highest pre-HSCT mortality rate (64.3%), compared with the non-infected children and those with non-refractory cytomegalovirus disease (10.1%) (p < 0.0001). CONCLUSION: Prevention and prompt control of cytomegalovirus infection, together with early HSCT/gene therapy, are crucial for improving the prognosis in children with IEI. WHAT IS KNOWN: ⢠Cytomegalovirus is the most frequent viral infection in children with inborn errors of immunity who are candidates to hematopoietic stem cell transplantation (HSCT). ⢠Active viral infections at the time of HSCT lead to worse prognosis. WHAT IS NEW: ⢠In children with inborn errors of immunity and indication of HSCT, refractory cytomegalovirus disease is associated with a very high mortality rate, compared with non-infected children and those with non-refractory cytomegalovirus disease. ⢠In patients with novel transplantation indications, the presence and treatment response of CMV infection should be considered to decide the best possible moment for HSCT.

BACKGROUND: DNA detection of human cytomegalovirus (hCMV) in cerebrospinal fluid (CSF) by polymerase chain reaction (PCR) is a marker of central nervous system (CNS) involvement in congenital hCMV infection (cCMV), but its prognostic value is unknown. METHODS: A multicenter, retrospective study was performed using the Spanish Congenital Cytomegalovirus Infection Database (REDICCMV; http://www.cmvcongenito.es). Newborns with cCMV and a lumbar puncture performed were included and classified according to their hCMV-PCR in CSF result (positive/negative). Clinical characteristics, neuroimaging abnormalities, plasma viral load, and audiological and neurological outcomes of both groups were compared. RESULTS: A total of 136 neonates were included in the study: 21 (15.4%) with positive CSF hCMV-PCR and 115 (84.6%) with negative results. Seventeen patients (81%) in the positive group were symptomatic at birth compared with 52.2% of infants in the negative group (odds ratio [OR], 3.86; 95% confidence interval [CI], 1.28-14.1; P = .01). Only 4 asymptomatic newborns (6.8%) had a positive CSF hCMV-PCR. There were no differences between groups regarding the rate of microcephaly, neuroimaging abnormalities, neurological sequelae at 6 months of age, or plasma viral load. Sensorineural hearing loss (SNHL) at birth was associated with a positive CSF hCMV-PCR result (OR, 3.49; 95% CI, 1.08-11.27; P = .04), although no association was found at 6 months of age. CONCLUSIONS: A positive hCMV-PCR result in CSF is associated with symptomatic cCMV and SNHL at birth. However, no differences in neuroimaging studies, plasma viral load, or outcomes at 6 months were found. These results suggest that hCMV-PCR in CSF may not be a useful prognostic marker in cCMV.

INTRODUCTION: Information about paediatric in-hospital antimicrobial usage and prescribing patterns to guide improvement strategies is scant. We aim to use an evaluation of the prevalence and appropriateness of antimicrobial prescription to identify antimicrobial stewardship priorities in children. METHODS: A cross-sectional point study was performed on hospitalised paediatric patients in a Spanish tertiary hospital, assessing the prevalence of antimicrobial prescription (PAP) and appropriateness of antimicrobial prescription (AAP). AAP was defined as a correct indication plus an appropriate prescribing pattern (dose, spectrum and interval). Evaluation was performed using established antimicrobial guidelines. Other factors that may have a bearing on antimicrobial prescription were also analysed. RESULTS: A total of 171 patients were included. PAP was 49.7% (85/171) and AAP was 60.9% (91/161). The most common indications for antimicrobial use were antimicrobial prophylaxis (28.3%, 32/113) and pneumonia (8.2%, 8/113). Overall, 161 antimicrobials were prescribed (1.9 antimicrobials per patient): 55.3% (89/161) were empiric, 16.1% (26/161) were targeted and 28.6% (46/161) were prophylactic. Amoxicillin/clavulanate (8.2%, 14/171) and sulfamethoxazole/trimethoprim (8.2%, 14/171) were the most prescribed antimicrobials. The prescription of antifungals (11.7%, 20/171) and antivirals (1.8%, 3/171) was analysed. Major causes of inappropriate antibiotic use were prolonged prescriptions (21.7%, 35/161) and use of agents with an excessively broad coverage spectrum (21.1%, 34/161). PAP and AAP varied between wards and antimicrobials. CONCLUSIONS: Measurement of PAP and AAP offers valuable information for detecting priorities in hospital settings and monitoring antimicrobial usage prior to the development of antimicrobial stewardship programmes. In our setting, the main areas for improvement are duration of therapy and proper use of broad-spectrum antimicrobials.

Mycoplasma pneumoniae (M. pneumoniae) is a bacterium with particular characteristics that give rise to a broad clinical spectrum, being respiratory infection the most frequent presentation. Infection by M. pneumoniae occurs in cyclical epidemics, and paediatricians in Spain have noticed an increase in cases since January 2024, establishing hospital registers to collect surveillance data (as it is not a notifiable disease in Spain). The diagnosis of infection by M. pneumoniae is made through serological testing and/or the detection of genetic material by means of polymerase chain reaction (PCR). Neither methods can differentiate between colonization and active infection, so a precise diagnosis is not possible and testing should only be requested in the case of high clinical suspicion. The role of antibiotherapy in infection by M. pneumoniae in its different clinical variants is not well defined. Most infections are self-limiting and mild, and there is insufficient evidence to support the use of antibiotherapy in these cases. Antibiotic treatment is justified in patients with risk factors for the development of severe disease (Down syndrome, anatomical or functional asplenia, immunosuppression), in hospitalized patients with respiratory infection and in patients with moderate or severe extrapulmonary forms. Taking into account aspects concerning the rational use of antimicrobials, the treatment of choice would be clarithromycin, with azithromycin as an alternative, reserving the use of doxycycline and levofloxacin for cases of antimicrobial resistance and/or infections of the central nervous system.

BACKGROUND AND OBJECTIVES: Antimicrobial stewardship programmes (ASPs) have resulted in antimicrobial consumption (AMC) reduction and quality of prescription (QOP) improvement. However, evidence of ASP impact in paediatrics is still limited. This study aims to assess a paediatric ASP long-term outcomes. METHODS: A quality improvement study assessed by a interrupted time series analysis was conducted in a paediatric tertiary hospital. QOP expressed as proportion of adequate prescriptions, AMC measured by defined daily dose incidence per 1000 occupied bed days, incidence density of bloodstream infections (BSIs) and its related all-cause crude death rate (CDR) were compared between pre (from January 2013 to December 2015) and post (from January 2016 to December 2019) ASP activities intensification, which included a dedicated paediatric infectious diseases physician to actively perform educational interviews with prescribers. RESULTS: Inappropriate prescribing showed a significant downward shift associated to the intervention with a -51.4% (-61.2% to -41.8%) reduction with respect to the expected values. Overall AMC showed no trend change after the intervention. For neonatology a28.8% (-36.8% to -20.9%) reduction was observed. Overall anti-pseudomonal cephalosporin use showed a -51.2% (-57.0% to -45.4%) reduction. Decreasing trends were observed for carbapenem use, with a quarterly per cent change (QPC) of -2.4% (-4.3% to -0.4%) and BSI-related CDR (QPC=-3.6%; -5.4% to -1.7%) through the study period. Healthcare-associated multi-drug-resistant BSI remained stable (QPC=2.1; -0.6 to 4.9). CONCLUSIONS: Intensification of counselling educational activities within an ASP suggests to improve QOP and to partially reduce AMC in paediatric patients. The decreasing trends in mortality remained unchanged.

INTRODUCTION: Paediatric infective endocarditis (IE) is a serious condition associated with significant mortality. Information in Spain is limited and comes from case series from single centres. The aim was to describe the epidemiology, clinical features, microbiology and outcome of paediatric IE in Andalusia. PATIENTS AND METHODS: Multi-centre descriptive observational retrospective study of patients <18 years old with a diagnosis of IE who were admitted to six Andalusian hospitals during 2008-2020. RESULTS: 44 episodes of IE (41 patients) with a median age of 103 months (IQR 37-150 months) were identified. Congenital heart disease (CHD) was the main predisposing factor, identified in 34 cases (77%). A total of 21 (48%) episodes of IE occurred in patients with prosthetic material. These had higher rate of CHD (p = 0.002) and increased end organ dysfunction (p = 0.04) compared to those with native valve. Fever was an almost universal symptom, associated in 23% of the episodes with heart failure. Staphylococcus aureus (25%) followed by coagulase-negative staphylococci (18%) and Streptococcus viridans (14%) were the most frequently isolated microorganisms, and three (7%) patients with central venous catheters had a fungal infection. Thromboembolic events were observed in 30% of the episodes, surgical intervention was required in 48% of cases. Mortality rate was 9%. Prosthetic material and CRP > 140 mg/L were independent predictors of complicated IE. CONCLUSIONS: Our findings emphasize the high morbidity of paediatric IE. The information provided could be useful for the identification of epidemiological and clinical profiles of children with IE and complicated forms.

Antimicrobial stewardship programs (ASPs) optimize antimicrobial use, improve patient outcomes, and reduce resistance. To assess the effectiveness of ASPs, it is necessary to have indicators that can be widely used. Defined daily dose (DDD) was designed by WHO for the adult population as a consumption indicator. However, there are no DDDs adapted to the pediatric population. The main objective of this study is to establish the most appropriate DDD values in this population. An observational, retrospective, multicenter study was conducted. Antimicrobial prescriptions were collected from pediatric wards of seven Spanish tertiary hospitals for 2 years. The DDDs obtained from the prescriptions were compared with the theoretical DDDs agreed upon in the first stage. To select the optimal DDD, the following were analyzed: power value, magnitude obtained from the differences in the DDD, statistical significance, and degree of agreement in the stipulated doses. A total of 4788 prescriptions were collected. Pediatric DDD was defined for 30 different antimicrobials. A potency >80% was obtained in 24 antibiotics. 51.2% of the selected DDD correspond to Phase I and 39.5% from Phase II. Pediatric DDD of different antimicrobials was obtained, providing an indicator that can be used globally in different hospitals to analyze the consumption and efficacy of ASPs.
ABSTRACT
In the past few years, antimicrobial resistance has increased, becoming a serious public health problem. The irrational use of antimicrobials is one of the main contributors to antimicrobial resistance. The paediatric population is not free from this problem, as antimicrobials are widely prescribed in this age group, often inappropriately. The introduction of antimicrobial stewardship programmes (ASPs) has proven crucial in curbing the emergence of antimicrobial resistance. At the international level, the need to develop specific paediatric ASPs has been recognised on account of the differences between adult and paediatric patients as concerns infection and approaches to diagnosis and treatment. For this reason, paediatric ASPs should be multidisciplinary programmes led by paediatric infectious disease specialists and use specific paediatric indicators (such as days of treatment, antimicrobial susceptibility patterns in the paediatric population, or clinical indicators) to help identify areas of improvement and develop effective targeted interventions. On the other hand, the support and leadership of the pertinent scientific societies are also essential. The purpose of this document is to present the position of the Sociedad Española de Infectología Pediátrica (SEIP, Spanish Society of Paediatric Infectious Diseases) concerning the implementation of paediatric ASPs in hospitals in Spain and to provide tools to facilitate their application in hospitals throughout the regional health care systems in the country.

Vancomycin is used to treat a wide variety of infections within the pediatric population. In adults, continuous infusion of vancomycin (CIV) has been evaluated as an alternative to intermittent infusion of vancomycin (IIV) with potential advantages. In children, the use of CIV is increasing; however, data is currently limited. The objective is to provide efficacy and safety evidence for CIV within this population. The review was carried out following PRISMA guidelines. A bibliographic search was performed for studies on PubMed and EMBASE. Clinical trials and observational studies that reported clinical efficacy and/or target attainment of CIV in pediatrics were included. Articles were reviewed to assess their design and target population, characteristics of vancomycin treatment and the main findings in terms of safety and efficacy. A total of 359 articles were identified, of which seven met the inclusion criteria. All of them evaluated the target attainment, six assessed safety but only three assessed clinical efficacy. The best administration method for this antibiotic within the pediatric population is still unknown due to limited evidence. However, studies conducted thus far suggest pharmacokinetic advantages for CIV. Further investigation is required, in particular for studies comparing IIV with CIV for clinical efficacy and toxicity outcomes.
ABSTRACT
BACKGROUND: Data on SARS-CoV-2 transmission among children living with healthcare workers (HCWs) are scarce. METHODS: A cross-sectional study was performed at a tertiary Hospital in Madrid, including children of HCW who suffered from SARS-CoV-2 infection between March and May 2020. Children underwent enzyme-linked immunosorbent serological study for detecting SARS-CoV-2 antibodies: VIRCELL IgG assay. RESULTS: One hundred thirteen children from 69 HCWs with confirmed SARS-CoV-2 infection were recruited: 47 children had positive IgG (41.6%). Children secondary attack rate was 43.7% (25% if both parents have had asymptomatic infection; 39.5% if one parent was symptomatic; and 47% when both parents had symptoms). Having a positive sibling was associated with a positive IgG result (odds ratio = 12.2; 95% confidence interval: 4.4-33.7, P < 0.001). Median age was higher in IgG positive children (P = 0.022). Children who referred anosmia presented higher IgG titles (P < 0.04). CONCLUSIONS: We observed a very high SARS-CoV-2 transmission in children of HCW during the first pandemic wave, especially when both parents were symptomatic. Having a positive sibling was associated with seroconversion, supporting the important role of family clusters in the transmission of SARS-CoV-2.

BACKGROUND: Visceral leishmaniasis (VL) is an endemic in Southern Europe. However, details regarding disease burden, clinical presentations, laboratory markers, management and outcome in children are scarce. METHODS: Medical records of children (<14 years) admitted with VL to 10 pediatric units in Andalusia (2004-2019) were retrospectively reviewed. VL diagnosis was based on clinical presentation, serology, microscopy and molecular methods. Diagnosis of secondary hemophagocytic lymphohistiocytosis (sHLH) was established using the hemophagocytic lymphohistiocytosis-2004 criteria. RESULTS: A total of 127 patients were identified. Median age was 14.5 months; the main clinical presentations were fever and splenomegaly (95.3% each). Cytopenias were the most common laboratory abnormalities. Diagnostics as well as treatment regimens varied over time and the participating centers. Liposomal amphotericin B was prescribed in 97.6%; relapses as well as adverse events were rarely observed (3.1% each). Thirty-seven patients, diagnosed with sHLH required longer hospital admission (P = 0.001), an increased number of platelet (P < 0.006) and red blood cell (P = 0.0001) transfusions and pediatric intensive care unit admission (P = 0.007). Monocytopenia (P = 0.011) and high C-reactive protein levels (P = 0.031), variables not included in the hemophagocytic lymphohistiocytosis-2004 criteria, were associated with sHLH. One patient deceased in the context of the Leishmania infection. CONCLUSIONS: We report data on the largest pediatric VL cohort from Europe, commonly associated with sHLH. Raised C-reactive protein levels and monocytopenia appear to be associated with sHLH. The latter may help to identify these patients and to guide decisions regarding need of additional supportive clinical care and immunomodulatory therapies. The observed high rate of heterogeneity in terms of diagnosis and management warrants the establishment of appropriate guidelines.

OBJECTIVE: Few data exist regarding the impact of antimicrobial stewardship programs on antifungal use. We evaluated the efficacy and safety of a comprehensive long-term antimicrobial stewardship program (ASP) focused on antifungal use. METHODS: During a 9-year period, we quarterly assessed antifungal consumption, incidence density of hospital-acquired candidemia, Candida spp. distribution, antifungal resistance, and crude death rate per 1000 occupied bed days (OBDs) of hospital-acquired candidemia. We performed segmented regression analysis of interrupted time series. RESULTS: A significant change in trend was observed for antifungal consumption, with a sustained reduction of -0.87% per quarter (95% confidence interval [CI], -1.36 -0.38, p < 0.001), accounting for a final reduction of -38.4%. The main reduction was produced in fluconazole, with a sustained reduction of -1.37% per quarter (95%CI, -1.96 -0.68, p<0.001). The incidence density of hospital-acquired candidemia decreased, with a change in slope of -5.06% cases per 1000 OBDs per year (95%CI, -8.23 -1.77, pâ¯=â¯0.009). The 14-day crude death rate per 1000 OBDs dropped from 0.044 to 0.017 (-6.36% deaths per 1000 OBDs per year; 95%CI, -13.45 -1.31, pâ¯=â¯0.09). CONCLUSIONS: This ASP has succeeded in optimizing the use of antifungal with a long-lasting reduction without increasing the incidence, neither the mortality, of hospital-acquired candidemia.

Primary immunodeficiencies (PIDs) are rare, undiagnosed and potentially fatal diseases. Clinical manifestations of PID can be fatal or leave sequelae that worsen the quality of life of patients. Traditionally, the treatment of PIDs has been largely supportive, with the exception of bone marrow transplantation and, more recently, gene therapy. The discovering of new affected pathways, the development of new molecules and biologics, and the increasing understanding of the molecular basis of these disorders have created opportunities in PIDs therapy. This document aims to review current knowledge and to provide recommendations about the diagnosis and clinical management of adults and children with PIDs based on the available scientific evidence taking in to account current practice and future challenges. A systematic review was conducted, and evidence levels based on the available literature are given for each recommendation where available.

A progressive increase in the incidence of infections caused by multidrug-resistant microorganisms is being reported. Among these resistant microorganisms, the main threats are extended-spectrum ß-lactamase-, AmpC-, and carbapenemase-producing Gram-negative bacilli, methicillin-resistant Staphylococcus aureus and vancomycin-resistant Enterococcus faecium. To address this important problem, it is essential to establish pediatric Antimicrobial Stewardship programs, perform active epidemiological surveillance and develop an adequate infection control policy. The therapeutic approach of these infections is often complex, frequently requiring antibiotics with less experience in children. In this position document made by the Spanish Association of Pediatrics and the Spanish Society of Pediatric Infectious Diseases, the epidemiology and treatment of these infections are reviewed according to the best available evidence.

INTRODUCTION: Antimicrobial defined daily dose (DDD), has limitations for antimicrobial consumption measurement in paediatrics. An alternative DDD design applicable for children is proposed. METHODS: Children (<16 years-old) from 10 Spanish hospitals during a 12-months period were included. Weight for age (50th percentile) was calculated for the median age of the cohort using standardized World Health Organization tables. DDD (g) for each antimicrobial was calculated by multiplying the obtained weight times the recommended dose (mg/kg) of the antimicrobial for the most common infectious indication. RESULTS: A total of 40,575 children were included. Median age was 4.17 (IQR: 1.36-8.98) and 4.81 (IQR: 1.42-9.60) years for boys and girls, respectively. Mean weight for this age was 17.08kg. Standardized DDD for representative antimicrobials were calculated. CONCLUSIONS: A useful method for antimicrobial DDD measurement in paediatrics has been proposed and should be validated in future studies for its use in paediatric antimicrobial stewardship programmes.

BACKGROUND: Detection of cytomegalovirus (CMV) DNA by real-time polymerase chain reaction (rt-PCR) in dried blood spots (DBSs) collected for newborn screening has been assessed for retrospective diagnosis of congenital CMV (cCMV) infection, with variable results (sensitivities ranging from 34% to 100%). We aimed to assess the accuracy of this technique in Spain in a large patient series. METHODS: Ambispective, multicenter study including patients with confirmed cCMV from the Spanish Registry of cCMV patients. cCMV was established on the presence of CMV DNA in any body fluid, by positive culture findings or by molecular techniques during the first 2 weeks of life. Children in whom cCMV had been excluded were used as negative controls. Neonatal DBS samples were collected from both groups. The presence of CMV DNA was assessed by rt-PCR (RealStar CMV, Altona, Germany) in a central laboratory. RESULTS: One-hundred three patients and 81 controls from 10 hospitals were included. The performance of CMV DNA determination in DBS for the diagnosis of cCMV was as follows (95% confidence interval): sensitivity 0.56 (0.47-0.65), specificity 0.98 (0.91-0.99), positive likelihood ratio 22.81 (5.74-90.58) and negative likelihood ratio 0.45 (0.36-0.56). Sensitivity increased with the birth viral load (bVL) log category. In cCMV patients, lower bVL was the single variable associated with a negative DBS rt-PCR result (P = 0.017). CONCLUSIONS: The sensitivity of CMV rt-PCR in DBS in our series was low and correlated with the bVL. Thus, a negative DBS result would not rule out cCMV infection, especially in patients with a low viremia level at birth.

Durante los últimos años ha habido un aumento en la aparición de resistencias antimicrobianas, lo cual supone un grave problema de salud pública. El mal uso de antimicrobianos es un factor determinante en su desarrollo. La población pediátrica no queda exenta de dicha problemática ya que la prescripción de antibióticos en pediatría es elevada, y en muchas ocasiones inadecuada.La incorporación de los programas de optimización de uso de antimicrobianos (PROA) ha resultado ser una medida crucial para disminuir el riesgo en la aparición de resistencias antibióticas. A nivel internacional se reconoce la necesidad de crear PROA específicos en pediatría (PROA-P) debido a las diferencias existentes entre pacientes adultos y pediátricos en referencia a las infecciones, así como al abordaje tanto diagnóstico como terapéutico de las mismas. Por esta misma razón, los PROA-P deben ser programas multidisciplinares liderados por especialistas en infecciones pediátricas y trabajar con indicadores específicos pediátricos (DOT, patrones de sensibilidad antibiótica de población pediátrica, indicadores clínicos ), que permitan detectar puntos de mejora y establecer estrategias dirigidas eficaces. Por otro lado, es imprescindible el apoyo y liderazgo por parte de las distintas sociedades científicas implicadas.El objetivo de este documento es dar a conocer el posicionamiento de la Sociedad Española de Infectología Pediátrica (SEIP) sobre la implementación de los PROA pediátricos hospitalarios en nuestro territorio, así como aportar herramientas que ayuden en la aplicación de dichos programas en los diferentes hospitales de las distintas regiones sanitarias del país.
