RESUMO

BACKGROUND: Congenital cytomegalovirus infection (CMVc) affects 0.7%-6% of recent births. Among its clinical manifestations are low weight and length at birth. OBJECTIVE: Describe the growth patterns of children with CMVc in their early years. METHODS: Observational, multicenter study of patients with CMVc. Anthropometric data were collected during the first 2 years of life and compared with World Health Organization standards. RESULTS: Anthropometric characteristics of 383 children with CMVc were studied, of which 198 (51%) were symptomatic at birth. At birth, 9% were small for gestational age (SGA) in terms of their weight and length and 17% had microcephaly. At 24 ± 3 months, 10% had a weight and length ≤2 SD, and 13% a head circumference ≤2 SD. Of those who were SGA at birth, at 24 ± 3 months >20% remained at ≤2 SD of their weight and length. Conversely, 75% of children with low weight or length at 24 ± 3 had not been SGA at birth. 20% of infants with microcephaly at birth remained with microcephaly, and 10% of those without microcephaly developed it at 24 ± 3 months. The average growth rate in length and weight was normal. Patients who were symptomatic at birth, premature and with motor and neurocognitive impairment had a significantly higher risk of low weight and length at 24 ± 3 months. CONCLUSION: Around 10% of children with CMVc are at ≤2 SD in weight, length and head circumference at 24 ± 3 months. The lack of adequate growth is associated with symptoms at birth, prematurity and motor and neurocognitive impairment. Growth impairment could be incorporated into the symptomatic spectrum of CMVc.

RESUMO

Introducción: El contacto sexual es actualmente en España la primera vía de contagio de VIH. Pese a los descensos en el número de nuevas infecciones en mujeres y consumo de drogas, en hombres se mantiene estable. El presente estudio pretende evaluar conductas de riesgo y conocimientos sobre VIH en una muestra de jóvenes en España. Métodos: Se realizó un estudio observacional descriptivo transversal utilizando un cuestionario sobre salud sexual y conocimiento sobre el VIH adaptado del Instituto Nacional de Estadística. El grupo estuvo compuesto por jóvenes no infectados por VIH. Se incluyó la variable riesgo sexual (alto y bajo), siendo de riesgo alto los sujetos que habían tenido tres o más parejas y no utilizaban preservativo en todas las relaciones. Resultados: Se encuestaron 243 jóvenes (65,6% mujeres) de entre 16 y 36 años (media = 25,7; DE = 4,1) (16-24 años: 134 sujetos; 25-29 años, 60 sujetos; más de 30 años, 47 sujetos). El 40,9% contestaron que utilizaban el preservativo en todas sus relaciones y el 61% que no perciben ningún riesgo de infección. De forma mayoritaria no se encuentran diferencias significativas en conocimiento sobre vías de transmisión entre los grupos de alto y de bajo riesgo. Los métodos de protección que se asociaron significativamente con las diferencias en riesgo sexual fueron lavarse tras las relaciones sexuales, tener pocas parejas, uso de espermicidas y carga viral indetectable (p < 0,05). Conclusiones: El principal resultado del estudio es la infravaloración personal de riesgo indicado según las diferencias encontradas entre la valoración personal y el índice de riesgo sexual. Se encuentran resultados tanto positivos como negativos en cuanto al conocimiento sobre el VIH


Introduction: Sexual intercourse is currently the main route of HIV infection in Spain. Despite decreases in new infections among women and drug users, the rate remains stable in men. The aim of this study was to assess risk behaviour and HIV awareness in a sample of young adults in Spain. Methods: A cross-sectional, observational, descriptive study was performed on a non-HIV infected sample, using a questionnaire on sexual health and HIV awareness adapted from the Spanish National Institute of Statistics. A sexual risk variable was included (high and low), which was classified as high if subjects had had three or more sexual partners and did not always use a condom in all their sexual encounters. Results: 243 subjects were included (65.6% women) aged between 16 and 36 years (mean = 25.7; SD = 4.1) (16-24 years: 134 subjects; 25-29 years: 60 subjects; over 30 years: 47 subjects). Approximately 40.9% said that they used a condom in all sexual relations and 61% did not perceive any risk of infection. There were no significant differences in awareness of infection routes between the high and low risk profiles. Washing after sex, having few partners, spermicide use and having undetectable viral load were protective measures significantly associated with differences in sexual risk (P < .05). Conclusions: The main finding of the study was the underestimation of risk of infection, analysed after differences found between self-assessment and sexual risk. Both positive and negative results were found concerning HIV awareness

RESUMO

INTRODUCTION: Cytomegalovirus (CMV) is the leading cause of congenital infection worldwide. Data about the management of CMV infection in pregnant women are scarce, and treatment options are very limited. The aim of the study is to investigate the effectiveness of cytomegalovirus hyperimmune globulin (CMV-HIG) for the prevention and treatment of congenital CMV (cCMV) infection. MATERIALS AND METHODS: A retrospective observational study was conducted in three tertiary hospitals in Madrid. In the period 2009-2015, CMV-HIG (Cytotect® CP Biotest, Biotest) treatment was offered to all pregnant women with primary CMV infection and/or detection of CMV-DNA in amniotic fluid in participating centers. Women were divided into prevention and treatment groups (PG and TG, respectively). Those with primary CMV infection who had not undergone amniocentesis comprised the PG and received monthly CMV-HIG (100 UI/kg). If CMV-DNA was subsequently detected in amniotic fluid, one extra dose of CMV-HIG (200 UI/kg) was given 4 weeks after the last dose. Those women were considered to be part of the PG group despite detection of CMV-DNA in amniotic fluid. In the case of a negative result in CMV-DNA detection in amniotic fluid or if amniocentesis was not performed, monthly HIG was given up to the end of the pregnancy. RESULTS: Thirty-six pregnant women were included. Median gestational age at birth was 39 weeks (interquartile range: 38-40) and two children (5.5%) were premature (born at 28 and 34 weeks' gestation). Amniocentesis was performed in 30/36 (83.4%) pregnancies and CMV PCR was positive in 21 of them (70%). One fetus with a positive PCR in amniotic fluid that received one dose of HIG after amniocentesis presented a negative CMV-PCR in urine at birth, and was asymptomatic at 12 months of age. Twenty-four children were infected at birth, and 16/21 (76.2%) presented no sequelae at 12 months, while two (9.5%) had a mild unilateral hearing loss and three (14.3%) severe hearing loss or neurological sequelae. Seventeen women were included in the PG and 19 in the TG. In the PG 7/17 (41%) fetuses were infected, one pregnancy was terminated due to abnormalities in cordocentesis and one showed a mild hearing loss at 12 months of age. In the TG, 18/19 children (95%) were diagnosed with cCMV, while the remaining neonate had negative urine CMV at birth. Eight out of the 19 fetuses (42.1%) showed CMV related abnormalities in the fetal US before HIG treatment. Complete clinical assessment in the neonatal period and at 12 months of age was available in 16 and 15 children, respectively. At birth 50% were symptomatic and at 12 months of age, 4/15 (26.7%) showed a hearing loss and 3/15 (20%) neurologic impairment. Fetuses with abnormalities in ultrasonography before HIG presented a high risk of sequelae (odds ratios: 60; 95%CI: 3-1185; p = .007). DISCUSSION: Prophylactic HIG administration in pregnant women after CMV primary infection seems not to reduce significantly the rate of congenital infection, but is safe and it could have a favorable effect on the symptoms and sequelae of infected fetuses. The risk of long-term sequelae in fetuses without US abnormalities before HIG is low, so it could be an option in infected fetuses with normal imaging. On the other hand, the risk of sequelae among infected fetuses with abnormalities in fetal ultrasonography before HIG despite treatment is high.

RESUMO

BACKGROUND: Detection of cytomegalovirus (CMV) DNA by real-time polymerase chain reaction (rt-PCR) in dried blood spots (DBS) 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 (REDICCMV). 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, Hamburg, Germany) in a central laboratory. RESULTS: One-hundred and 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% CI): sensitivity 0.56 (0.47-0.65), specificity 0.98 (0.91-0.99), positive likelihood ratio 22.81 (5.74-90.58), 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). CONCLUSION: 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.

RESUMO

INTRODUCTION: PFAPA syndrome is an autoinflammatory disease whose diagnosis is mainly clinical. Several treatments have been proposed; among them, tonsillectomy could be an effective one. MATERIAL AND METHODS: Retrospective multicenter study. Patients included were diagnosed with PFAPA syndrome, according to the Thomas criteria, in 3 hospitals in Madrid between 2009-2013. RESULTS: Thirty-two cases were included. Median age at onset and at diagnosis were 32 months (IQR 24-44) and 47.5 months (IQR 37-60), respectively. There were increases in leukocytes (13,580/µL [IQR 8,200-16,600] vs. 8,300/µL [IQR 7,130-9,650], P=.005), neutrophils (9,340/µL [IQR 5,900-11,620] vs. 3,660/µL [IQR 2,950-4,580], P=.002) and C-reactive protein (11.0mg/dL [IQR 6.6-12.7] vs. 0.2mg/dL [IQR 0.1-0.6], P=.003) during febrile episodes. In all, 80.8% of patients reported remission of symptoms within 24h after oral corticosteroid therapy. Fourteen patients were tonsillectomized. In 11, the febrile episodes stopped while, in 3, the frequency was reduced; there were 2 cases of postoperative bleeding. The disease was resolved in 56.3% of the patients, at a median age of 60 months (IQR 47-95), with similar duration in patients who were tonsillectomized and those who were not. CONCLUSIONS: We present a large cohort of children with PFAPA syndrome, with clinical and analytical features similar to those described in the literature, and a good response to corticosteroids and a high resolution rate of symptoms after tonsillectomy.

RESUMO

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.

RESUMO

BACKGROUND: Premature infants have lower short-term immune responses to vaccination than term infants, but patterns of antibody persistence in preterm infants over longer periods are not well established. This study assessed the persistence of antibody response to the 13-valent pneumococcal conjugate vaccine (PCV13) in formerly preterm versus term infants. METHODS: In total, 100 preterm and 100 term infants received PCV13 with routine vaccines at ages 2, 3, 4 and 12 months. Serotype-specific anticapsular immunoglobulin G (IgG)-binding antibodies and opsonophagocytic activity were determined 1 and 2 years after the last PCV13 dose. RESULTS: At 1 and 2 years after the last vaccination (toddler dose), IgG geometric mean concentrations (GMCs) for all serotypes had declined from levels measured 1 month after the toddler dose but remained above pretoddler dose levels. IgG GMCs were significantly lower in preterm than term subjects for a majority of serotypes at both follow-up time points. IgG GMCs increased in both groups for some serotypes from the 1-year to 2-year follow-up, whereas others declined. Opsonophagocytic activity results supported the IgG results. CONCLUSIONS: The routine (3 + 1) vaccination schedule is likely to offer long-term protection against invasive pneumococcal disease in preterm infants and should be initiated regardless of gestational age or weight at birth, without delay of the toddler dose.

RESUMO

BACKGROUND: Children are at higher risk of tuberculosis (TB) dissemination and extrapulmonary disease, contributing greatly to TB-associated morbidity and long-term sequelae. However, there are very few studies that assess the impact and clinical spectrum of pediatric extrapulmonary TB (EPTB) in low-prevalence regions. METHODS: Children <18 years of age diagnosed with TB in Madrid region (2005-2013) were reviewed. We compared the epidemiology, clinical characteristics and the performance of diagnostic tests in childhood extrapulmonary and pulmonary disease. We performed a multivariate logistic regression to identify factors associated with EPTB. RESULTS: During the study period, 93 of 526 pediatric TB cases had EPTB (17.7%). The most common site was lymphatic TB (34.5%). The source case was not identified in most extrapulmonary cases, contrary to pulmonary TB (28% vs. 63.3%; P < 0.001). The tuberculin-skin-test induration was smaller in EPTB cases (<5 mm 22% vs. 5%; P < 0.001), but the sensitivity of interferon-gamma-release-assays was similar (76.9% vs. 79.4%). Children with EPTB presented higher rate of bacteriologic confirmation (66% vs. 49.4%; P < 0.01), and higher incidence of multidrug resistant TB (8.2% vs. 1.6%; P = 0.03). Complications were present in 40.2% extrapulmonary cases. EPTB was associated with the child's foreign origin [odds ratio (OR) 2.3 (1.1-5.3)], immune disorders [OR 5.8 (1.9-17.1)] and drug resistance [OR 2.4 (1.1-5.4)]. CONCLUSIONS: In our low-prevalence region, childhood EPTB was linked to immigrant status, immune disorders and drug resistance, and presented high rate of complications. Our study underscores the relevance of improved diagnostic tools and systematic TB screening in high risk populations.

RESUMO

La histiocitosis de células de Langerhans es una enfermedad infrecuente en el lactante y su presentación como una adenitis cervical aislada sin otra sintomatología es excepcional en estos pacientes. Se describe el caso de una lactante de 3 meses de edad que presentaba una tumoración cervical en el ángulo mandibular derecho, con mala respuesta al tratamiento antibiótico. Se realizó una punción-aspiración con aguja fina, que confirmó el diagnóstico de histiocitosis de células de Langerhans. El estudio de extensión no mostró afectación sistémica. Debe considerarse la histiocitosis de células de Langerhans en el diagnóstico diferencial de una masa cervical subaguda de evolución tórpida en los lactantes de corta edad y se debe plantear la realización de una punción-aspiración con aguja fina de manera precoz para establecer el diagnóstico.


Langerhans cell histiocytosis in infants is a rare condition, and presentation as an isolated cervical adenitis is exceptional at this age. We describe the case of a 3-month-old female infant presenting with a neck mass in the right mandibular angle with poor response to antibiotic treatment. Fine needle aspiration was performed and confirmed the diagnosis of Langerhans cell histiocytosis with complementary tests showing no features of systemic involvement. Langerhans cell histiocytosis should be considered in the differential diagnosis of subacute neck masses with poor outcome in infants and physicians should consider performing a fine needle aspiration to establish the diagnosis.

RESUMO

INTRODUCTION: Kawasaki disease refers to systemic vasculitis with risk of coronary artery disease. Our objective is to identify risk factors associated with coronary artery disease in patients with complete and incomplete Kawasaki disease. MATERIAL AND METHODS: Descriptive, retrospective study conducted in patients diagnosed with Kawasaki disease in a tertiary-care hospital between 2008 and 2014. The American Heart Association diagnostic criteria were used to define complete and incomplete Kawasaki disease. RESULTS: Thirty-one children were diagnosed with Kawasaki disease; 24 met the criteria for the complete form, and 7, for the incomplete form of this condition. Five had coronary artery disease. One of them had incomplete Kawasaki disease (1/7= 14.3%), and the remaining four had the complete form (4/24= 16.7%). No significant differences were found between both groups (p= 1.0). Patients with coronary artery involvement had a higher C-reactive protein level (median: 16.2 mg/dL versus 8.4 mg/dL, p= 0.047) and lower albuminemia (median: 3.2 mg/dL versus 3.99 mg/dL, p= 0.002). CONCLUSIONS: The risk of coronary artery involvement in incomplete Kawasaki disease is similar to that in complete Kawasaki disease; therefore, in patients with the incomplete form, immunoglobulin therapy should not be delayed. In our population, C-reactive protein and albumin levels were related to a higher risk of coronary artery involvement.

RESUMO

Background. Human cytomegalovirus is a leading cause of congenital infection, and there are limited data on prognosis markers in disease development. We aimed to study 3 virology targets (glycoprotein [g]B, gN, and UL144) to assess their correlation with congenital infection and various organ system involvement. Methods. Forty-eight congenital cases and 58 postnatally infected children were included (2003-2014). Genotyping for the 3 targets and distribution among the cohorts were investigated, and the relationship between the gB, gN, and UL144 types with clinical manifestations in congenital infection was also studied. Results. All of the genotypes were similarly represented among cohorts, and the most prevalent were the UL144B, gB1, and gN1 genotypes. The gB2 genotype was associated with abnormal image findings by ultrasound and/or magnetic resonance in congenital infection (odds ratio [OR], 6.2; 95% confidence interval [CI], 1.1-34.3; P = .036); the gN1 genotype was associated with an elevated risk of developing neurological disorders (OR, 7.0; 95% CI, 1.1-45.9; P = .043). Both gN1 and gB2 were independent factors for symptomatic infection. Statistical analyses showed no association between any UL144 genotype and disease severity. Conclusions. All of the genotypes can be involved in congenital infection, although the gB2 and gN1 genotypes might be associated with a more serious illness.

RESUMO

Acquired hemophagocytic lymphohistiocitosis (HLH) syndrome can be a complication of visceral leishmaniasis (VL). A multicenter prospective study was conducted to determine the frequency of HLH syndrome in children with VL. Twenty-four children with VL were identified, and 10 (41%) developed HLH syndrome. VL should be ruled out in all children with HLH criteria living in or coming from endemic areas.

RESUMO

OBJECTIVES: This study evaluated the immune response and safety profile of 13-valent pneumococcal conjugate vaccine (PCV13) in preterm infants compared with term infants. METHODS: This Phase IV, open-label, 2-arm, multicenter, parallel-group study enrolled 200 healthy infants (preterm, n = 100; term, n = 100) aged 42 to 98 days. All subjects received PCV13 at ages 2, 3, 4 (infant series), and 12 (toddler dose [TD]) months, together with routine vaccines (diphtheria-tetanus-acellular pertussis, hepatitis B, inactivated poliovirus, and Haemophilus influenzae type b vaccine and meningococcal group C conjugate vaccine). RESULTS: Most subjects achieved an anticapsular immunoglobulin G (IgG) antibody concentration ≥ 0.35 µg/mL for all serotypes: >85% after the infant series (except preterm infants for serotypes 5, 6A, and 6B) and >97% after TD (except for serotype 3). Preterm infants had overall lower IgG geometric mean concentrations compared with term infants; however, geometric mean fold increases after TD were similar for all serotypes. Opsonophagocytic activity results were consistent with IgG results and titers increased after TD in both groups for all serotypes, including serotype 3. PCV13 was generally well tolerated, with similar safety profiles in all preterm subgroups. CONCLUSIONS: Immune responses were lower in preterm infants than in term infants. However, the majority of subjects in both groups achieved both pneumococcal serotype-specific IgG antibody levels after the infant series that exceeded the World Health Organization-established threshold of protection and functional antibody responses. Responses were uniformly higher after TD, reinforcing the importance of a timely booster dose. PCV13 was well tolerated regardless of gestational age.

RESUMO

La trombosis aórtica es poco frecuente en el período neonatal. El principal factor de riesgo es la canalización de la arteria umbilical. Existen varias opciones de tratamiento, entre las que se encuentran la trombólisis, trombectomía y la anticoagulación, que se utilizan en función de la localización de la trombosis y de la clínica que produce. Presentamos el caso de un recién nacido que consulta por debilidad de pulsos femorales, frialdad y mala perfusión de miembros inferiores. Mediante la ecocardiografía, se descartó la coartación de aorta y, con ecografía Doppler abdominal, se observó la presencia de trombosis aórtica a nivel infrarrenal sin antecedentes de cateterismo umbilical.


The aortic thrombosis is not frequent during the neonatal period. The canalization of umbilical artery is the main risk factor. There are several options for the treatment, such as thrombolysis, thrombectomy and the anticoagulation, which are used in terms of the thrombosis localization and the symptoms that are observed. We present the case of a newborn who consulted for weak femoral pulses, coldness and poor perfusion of lower limbs. The aorta restriction was ruled out using the echocardiography; Doppler abdominal ecography showed aortic thrombosis at an underrenal level. There was not a previous umbilical catheterism.
