Rotavirus gastroenteritis hospitalizations in provinces with different vaccination coverage rates in Spain, 2013-2018. BMC Infect Dis 2021; 21:1138. [PMID: 34742235 PMCID: PMC8572461 DOI: 10.1186/s12879-021-06841-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Accepted: 10/29/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Rotavirus (RV) vaccines are available in Spain since 2006 but are not included in the National Immunization Program. RV vaccination has reached an intermediate vaccination coverage rate (VCR) but with substantial differences between provinces. The aim of this study was to assess the ratio of RV gastroenteritis (RVGE) admissions to all-cause hospitalizations in children under 5 years of age in areas with different VCR. METHODS Observational, multicenter, cross-sectional, medical record-based study. All children admitted to the study hospitals with a RVGE confirmed diagnosis during a 5-year period were selected. The annual ratio of RVGE to the total number of all-cause hospitalizations in children < 5 years of age were calculated. The proportion of RVGE hospitalizations were compared in areas with low (< 30%), intermediate (31-59%) and high (> 60%) VCR. RESULTS From June 2013 to May 2018, data from 1731 RVGE hospitalizations (16.47% of which were nosocomial) were collected from the 12 study hospitals. RVGE hospital admissions accounted for 2.82% (95 CI 2.72-3.00) and 43.84% (95% CI 40.53-47.21) of all-cause and Acute Gastroenteritis (AGE) hospitalizations in children under 5 years of age, respectively. The likelihood of hospitalization due to RVGE was 56% (IC95%, 51-61%) and 27% (IC95%, 18-35%) lower in areas with high and intermediate VCR, respectively, compared to the low VCR areas. CONCLUSIONS RVGE hospitalization ratios are highly dependent on the RV VCR. Increasing VCR in areas with intermediate and low coverage rates would significantly reduce the severe burden of RVGE that requires hospital management in Spain. Clinical trial registration Not applicable.

[Immunisation schedule of the Spanish Association of Paediatrics: 2015 recommendations]. An Pediatr (Barc) 2016; 82:44.e1-44.e12.

Abstract
The Advisory Committee on Vaccines of the Spanish Association of Paediatrics updates the immunisation schedule every year, taking into account epidemiological data as well as evidence on the safety, effectiveness and efficiency of current vaccines, including levels of recommendation. In our opinion, this is the optimal vaccination calendar for all children resident in Spain. Regarding the vaccines included in the official unified immunization schedule, the Committee emphasizes the administration of the first dose of hepatitis B either at birth or at 2 months of life; the recommendation of the first dose of MMR and varicella vaccine at the age of 12 months, with the second dose at the age of 2-3 years; DTaP or Tdap vaccine at the age of 6 years, followed by another Tdap booster dose at 11-12 years old; Tdap strategies for pregnant women and household contacts of the newborn, and immunization against human papillomavirus in girls aged 11-12 years old with a 2 dose scheme (0, 6 months). The Committee reasserts its recommendation to include vaccination against pneumococcal disease in the routine immunisation schedule, the same as it is being conducted in Western European countries. The recently authorised meningococcal B vaccine, currently blocked in Spain, exhibits the profile of a universal vaccine. The Committe insists on the need of having the vaccine available in communitary pharmacies. It has also proposed the free availability of varicella vaccines. Their efectiveness and safety have been confirmed when they are administred from the second year of life. Vaccination against rotavirus is recommended in all infants. The Committee stresses the need to vaccinate population groups considered at risk against influenza and hepatitis A.

Abstract
The Advisory Committee on Vaccines of the Spanish Association of Paediatrics (CAV-AEP) annually publishes the immunisation schedule which, in our opinion, estimates optimal for children resident in Spain, considering available evidence on current vaccines. We acknowledge the effort of the Ministry of Health during the last year in order to optimize the funded unified Spanish vaccination schedule, with the recent inclusion of pneumococcal and varicella vaccination in early infancy. Regarding the funded vaccines included in the official unified immunization schedule, taking into account available data, CAV-AEP recommends 2+1 strategy (2, 4 and 12 months) with hexavalent (DTPa-IPV-Hib-HB) vaccines and 13-valent pneumococcal conjugate vaccine. Administration of Tdap and poliomyelitis booster dose at the age of 6 is recommended, as well as Tdap vaccine for adolescents and pregnant women, between 27-36 weeks gestation. The two-dose scheme should be used for MMR (12 months and 2-4 years) and varicella (15 months and 2-4 years). Coverage of human papillomavirus vaccination in girls aged 11-12 with a two dose scheme (0, 6 months) should be improved. Information for male adolescents about potential beneficial effects of this immunisation should be provided as well. Regarding recommended unfunded immunisations, CAV-AEP recommends the administration of meningococcal B vaccine, due to the current availability in Spanish communitary pharmacies, with a 3+1 scheme (3, 5, 7 and 13-15 months). CAV-AEP requests the incorporation of this vaccine in the funded unified schedule. Vaccination against rotavirus is recommended in all infants. Annual influenza immunisation and vaccination against hepatitis A are indicated in population groups considered at risk.

Abstract
Candida yeasts are ubiquitous commensals, which can cause opportunistic infection in any location of the body. The source of infection may be both endogenous and exogenous. Invasive candidiasis encompasses different entities ranging from invasive candidiasis to disseminated multiorgan infection. Invasive candidiasis is the third leading cause of nosocomial bloodstream infection and the fourth of all nosocomial infections. It is also the most common invasive fungal infection in non-neutropenic critically ill patients, with a remarkable increase in the last 20 years owing to the increased survival of these patients and to more complex diagnostic, therapeutic and surgical procedures. Its incidence in infants, according to recent reviews, stands at 38.8 cases/100,000 children younger than 1 year. Candida albicans remains the most frequent isolate in invasive infections, although infections caused by other species have risen in the last years, such as C. kruzsei, C. glabrata and C. parapsilosis; the latter causing invasive candidiasis mainly associated with central venous catheter management, especially in neonatal units. The overall mortality of invasive candidiasis is high, with 30-day mortality reaching 20-44% in some series involving paediatric patients. This report provides an update on incidence, epidemiology, clinical presentation, diagnosis, treatment and outcome of invasive infection by Candida spp. in the paediatric patient.

Abstract
The purpose of this study is to evaluate the effects of neonatal thymectomy in the functional capacity of the immune system. We selected a group of 23 subjects, who had undergone thymectomy in their first 30 days of life, during an intervention for congenital heart disease. Several parameters of the immune system were evaluated during their first 3 years of life. Lymphocyte populations and subpopulations (including naive, memory and effector subpopulations), T cell receptor (TCR) Vbeta repertoire, response of T cells following in vitro stimulation by mitogen, quantification of immunoglobulins, TCR excision circles (TRECS) and interleukin (IL)-7 were measured. We found that neonatal thymectomy produces long-term diminution in total lymphocyte counts, especially in naive CD4+ and CD8+ T cells. Additionally, TRECS were decreased, and plasma IL-7 levels increased. A statistically significant negative correlation was found between absolute CD4+ T cells and IL-7 (r = -0.470, P = 0.02). The patients did not suffer more infectious events than healthy control children, but thymectomy in neonates resulted in a significant decrease in T lymphocyte levels and TRECS, consistent with cessation of thymopoiesis. This could produce a compromise in immune function later in life, especially if the patients suffer T cell depletion and need a reconstitution of immune function.

Abstract
It is of paramount importance to know the vaccination status in internationally adopted children, so that they can be correctly immunized. This study ascertains the seroprotection rate for vaccine-preventable diseases and the validity of the immunization cards in 637 adopted children. The absence of the immunization card (13% of children) correlated with a poor global vaccine protection. Children with immunization records (87%) had a better global seroprotection but the information obtained from the card did not accurately predict seroprotection for each particular antigen. The best variable to predict the status of seroprotection was the country of origin. The highest rate of protection was found in children from Eastern Europe and, in descending order, India, Latin America, China and Africa. General recommendations for immunization of internationally adopted children are difficult to establish. Actions for vaccination have to be mainly implemented on the basis of the existence of the immunization card and of the country of origin.

Abstract
AIMS To assess the "real life" effectiveness of different antiretroviral therapies (ART). METHODS A retrospective multicentre observational study in 150 HIV-1 vertically infected children on the progression to AIDS (study A), and in 61 HIV-1 infected children on the evolution of the most relevant markers of progression (study B). All children were categorised into four groups: untreated (NT); on monotherapy (MT); on combination therapy (dual-ART); and on potent ART (HAART). RESULTS No child in the HAART group progressed to AIDS, whereas 14 children in the NT and seven in the MT groups progressed to AIDS, respectively, the differences being statistically significant. There was a mean increase of 8 units of %CD4+ per year; this was greater in the HAART group than in the other groups. The mean decrease in viral load was 0.65 log(10) copies/ml per year; this was greater in the HAART group than in the NT and MT groups. The HAART group had the lowest probability of returning to baseline %CD4+ and viral load. CONCLUSION Potent ART had the greatest protective effect against progression to AIDS in this observational study.

Abstract
The presence of autoantibodies and autoimmune diseases was tested in all available members of five families with at least one member affected with X-linked chronic granulomatous disease. Patients and carriers relatives possess autoantibodies more frequently than non-carriers relatives (95% vs 10%, p < 1.0 x 10(-5), Fisher test). Further, a survey of the literature revealed that in X-linked immunodeficiencies with X-chromosome random inactivation, clear features of autoimmunity are observed, not found in those with non-random inactivation. It appears then as if random inactivation of the X-chromosome in these pathologies, may favor the expression of an autoimmune phenotype in patients and carriers.

Acute episodes of unexplained crying in infants may be due to serious and even life-threatening conditions. We present six infants in whom excessive crying was the predominant initial manifestation of sepsis for a period of time that ranged from 2 to 10 hours, before other symptoms or signs became evident. This led to a diagnostic delay in two patients who were considered initially to have infant colic. Sepsis should be considered in the differential diagnosis of acute unexplained crying in infants.

Abstract
A 14 year-old boy with X-linked chronic granulomatous disease (CGD) developed a long smooth narrowing at the mid oesophagus with severe dysphagia. Endoscopy revealed a normal mucosa and biopsy showed non-specific acute inflammatory changes. Bacterial cultures of the biopsy specimens were sterile. Combined treatment with antibiotics and steroids resulted in a transitory remission, but symptoms recurred after 2.5 months. One second course of steroids and antibiotics lead to a long-term remission. Oesophagogram was more useful than endoscopy to evaluate the severity of the stricture.

Abstract
Lupus-like lesions in X-linked chronic granulomatous disease (X-CGD) are rare. To our knowledge, only 2 cases have previously been published. We report a 2.5-year-old boy with X-CGD whose clinical findings were consistent with cutaneous lupus erythematosus. Conventional histopathology showed epidermal atrophy, parakeratosis, follicular plugging and areas of hydropic degeneration. The most striking feature was a neutrophilic interstitial infiltrate with leukocytoclasia in the upper dermis. The X chromosome of our patient--studied with 2 endonucleases (PstI and TaqI) and 5 probes (P99.6, pERT 87.8, pERT87.15, XJ1.1 and 754)--was recombinant, but we believe that this is an incidental finding, not related to the disease. Neutrophilic infiltrate and leukocytoclasia could be characteristic histopathologic findings of lupus-like lesions in these patients.

Abstract
In a prospective study, a commercial polymerase chain reaction (PCR) system was compared with a conventional procedure, based on PCR and hybridization with a radio-labeled probe, for the detection of human immunodeficiency virus (HIV) infection in 131 blood samples from 80 children born to HIV-seropositive mothers. Twenty-three of these children were HIV infected. The sensitivity and specificity of the commercial assay as compared with the conventional PCR procedure were 100% and 95.1%, respectively. This commercial method simplifies the performance of the conventional PCR technique and can be used to detect HIV type 1 vertical transmission.

Abstract
The aims of this retrospective study were to review the frequency and patterns of bacterial sepsis in children infected with human immunodeficiency virus. The charts of 233 human immunodeficiency virus-infected children cared for during a 10-year period in 4 tertiary hospitals in Madrid were reviewed. There were 43 episodes of sepsis in 31 (13%) children. Twenty of them had acquired immunodeficiency syndrome, 10 were class PA2 and 1 was class P1B. The most common organisms recovered were: nontyphoidal Salmonella, 10 cases (23%); Streptococcus pneumoniae, 9 cases (21%); Staphylococcus epidermidis, 6 cases (14%); Escherichia coli, 5 cases (12%); Enterococcus faecalis, 4 cases (9%); Campylobacter jejuni, 2 cases (5%). In 28 episodes of bacteremia there were other sites of associated infection: pneumonia, 6 cases; urinary tract infection (UTI), 5 cases; gastrointestinal disease, 4 cases; catheter-related bacteremia, 12 cases. Eight patients had more than 1 episode of bacteremia. The rate of complications was high: 6 children had septic shock; and 2 of them developed disseminated intravascular coagulation. There was 1 death directly related to sepsis.

In this study we have analysed the effect of CMV on T lymphocyte function in 29 children diagnosed for acute CMV infection. Peripheral blood mononuclear cells (PBMC) obtained from the patients showed a significant specific impairment in their proliferative response to enterotoxins A and C1, to concanavalin A and to the anti-CD3 MoAb OKT3. The impaired responses were corrected with exogenous IL-2. In contrast, stimulation using phytohaemagglutinin, as well as activation signals delivered through the surface molecules CD26 or CD28, elicited normal proliferative responses in CMV PBMC. The results indicate that the T cell anergy associated with CMV infection is restricted to the T cell receptor/CD3 activation pathway.

Abstract
OBJECTIVE To describe clinical profiles of Q fever in children. DESIGN Retrospective study. SETTING Tertiary teaching hospital. PARTICIPANTS Thirteen children aged 2 to 14 years, with a mean +/- SD age of 9.6 +/- 3.6 years. SELECTION PROCEDURES Review of the medical records of all children with Q fever admitted from 1986 to 1990. The diagnosis was made by detection of phase II antibodies to Coxiella burnetii by the complement fixation test. MEASUREMENTS/MAIN RESULTS Clinical profiles consisted of a self-limited illness characterized by high fever (mean +/- SD, 39.9 degrees C +/- 0.66 degrees C) of 5 to 10 days' duration (mean +/- SD, 7.4 +/- 1.6 days), constitutional symptoms, and mild liver dysfunction. Eleven patients had gastrointestinal manifestations (vomiting and/or abdominal pain). Respiratory symptoms were not prominent. Most patients had normal or low white blood cell counts, and seven showed a relative increase of band forms. Their erythrocyte sedimentation rates ranged from 8 to 23 mm/h. All patients did well without specific therapy for C burnetii. CONCLUSION In children with the symptoms described above, tests to detect antibodies to C burnetii should be performed.
