[PMID: 34715364 DOI: 10.1016/j.tmaid.2021.102185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 09/16/2021] [Accepted: 10/18/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Updated data on epidemiology of tuberculosis are needed in Italy. The aim of this study is to evaluate trends in incidence and associated lethality of tuberculosis in immigrants compared with Italians. METHODS All tuberculosis cases diagnosed from 2000 to 2018 in 31 Tuscan hospitals were retrospectively identified. RESULTS In 10,827 tuberculosis cases 6715 were males (62%), 4312 (60%) were Italian-born. Hospitalization rate was 15.37/100,000 population/year. The most common comorbidity were liver disease (832/10,827; 7.7%), COPD (675/10,827; 6.2%), cancer (614/10,827; 5.7%). HIV was more frequent in the immigrants (p < 0.001). Extra-pulmonary tuberculosis cases (EPTB) were mainly localized in pleura (740/3,894, 19%) and lymph nodes (449/3,894, 11,5%). HIV was associated with an increased risk of EPTB (OR 3.51 95% CI 2.92-4.23, p < 0.0001). EPTB risk was increased in South Asian-born patients (OR 1.77, 95% CI 1.46-2.15, p < 0.0001) as well in African-born patients (OR 1.13, 95% CI 1.03-1.24, p = 0.0091), who were at risk for gastroenteric tuberculosis (OR 3.74, 95% CI 2.69-5.22, p < 0.0001). Overall mortality rate was 0.006 per 1000. Most of death cases (89%) were Italians (p < 0.02) and mainly affected by pulmonary tuberculosis (PTB). CONCLUSIONS In Tuscany, tuberculosis is still a health concern in terms of both morbidity and mortality.

[PMID: 34130683 PMCID: PMC8205646 DOI: 10.1186/s12889-021-11230-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Accepted: 06/07/2021] [Indexed: 11/23/2022] Open
Abstract
Background Socioeconomic position (SEP) powerfully affects health status in the childhood population. However, the knowledge of which diseases are more affected by SEP and whose outcomes could be improved by having a more equitable society remains uncertain on a population basis. Methods We measured socioeconomic and gender inequalities in the pre-COVID-19 era for 29 diseases in the entire childhood population in Catalonia to identify which diseases are most impacted by inequalities. This population-based study included 1,449,816 children under 15 years old from 2014 to 2017 (48.52% girls) and each of their registered diagnoses within the Catalonia National Health System. We calculated frequency measures by SEP and their sex ratios for each disease. We estimated four regression-based inequality measures: slope index of inequality, relative index of inequality (RII), absolute population-attributable fraction, and population-attributable fraction. Results Twenty-five of the 29 diseases examined showed SEP inequalities. The diseases with the greatest inequalities in both sexes were tuberculosis, obesity, adjustment and anxiety disorders, essential hypertension, poisoning, short gestation, low birth weight, foetal growth retardation and intrauterine hypoxia and birth asphyxia and trauma (RII ≥ 2.0); only food allergy showed the opposite pattern (RII < 1.0). Overall, 80,188 (7.80%) of the disease events in boys and 74,921 (8.88%) in girls would be avoided if all children had the same disease rate as those in the medium-high SEP group, with tuberculosis, intrauterine hypoxia and birth asphyxia and trauma, obesity, and short gestation, low birth weight, foetal growth retardation being those that could be reduced the most in relative terms, and dermatitis, injuries, acute bronquitis, and being overweight those that could be reduced the most in absolute terms. Girls present higher RII than boys for respiratory allergy, asthma, dermatitis, being overweight, and obesity (p < 0.05). In contrast, boys showed higher RII compared to girls only in congenital anomalies (p < 0.05). Conclusions Socioeconomic and gender inequalities are widely present in childhood health. This indicates that SEP plays a common role in their development although it varies in magnitude according to each disease. It is also a phenomenon that comprises all SEP groups in society. Action needs to be taken to ensure a fairer start in life in terms of health. Supplementary Information The online version contains supplementary material available at 10.1186/s12889-021-11230-9.

Abstract
INTRODUCTION Tuberculosis (TB) continues to be a serious public health problem and establishing a definitive diagnosis among children is extremely challenging. Pulmonary tuberculosis is the most prevalent form, with children under the age of 2 years being at greatest risk of severe and disseminated forms. The aim of this study was to describe TB among children in Spain in recent years. PATIENTS AND METHODS A retrospective study of paediatric patients diagnosed with TB in two hospitals of the Community of Madrid over a 26-year period (1991-2017). Epidemiological and clinical variables, additional tests and treatments received were analysed. RESULTS 170 children were included. The two most-affected age groups were infancy and adolescence. 42.9% of patients were immigrant children (South-America or Morocco). The main reasons for consultation were TB contact (20.6%) and fever (15.3%). At diagnosis, 61.8% of cases referred an epidemic environment, and 30.6% were asymptomatic. The Mantoux tuberculin skin test was positive in 92.2% of patients and IGRA was positive in 70.6%. Pulmonary TB was identified in 91.8% of children vs. 8.2% with extrapulmonary forms. Gastric juice culture was positive in 36.9% of cases and three strains resistant to isoniazid were isolated. All patients were cured without complications except one who died. CONCLUSIONS Pulmonary TB continues to be the most prevalent form among children and presumptive diagnosis (symptoms consistent with positive Mantoux test or suggestive X-ray) is the most common form of diagnosis. It is important to conduct a contact investigation in order to control the spread of TB.

Abstract
The epidemiology of tuberculosis (TB) in high-income countries is increasingly dictated by immigration. The influence of this trend on paediatric TB and TB elimination are not well defined. We undertook a 25-year conventional and molecular epidemiologic study of paediatric TB in Alberta, one of four major immigrant-receiving provinces in Canada. All isolates of Mycobacterium tuberculosis were DNA fingerprinted using standard methodology. Between 1990 and 2014, 176 children aged 0–14 years were diagnosed with TB. Foreign-born children or Canadian-born children of foreign-born parents accounted for an increasingly large proportion of total cases during the study period (from 32.1% to 89.5%). Of the 78 culture-positive cases, 35 (44.9%) had a putative source case identified by conventional epidemiology, with 34 (97.1%) having a concordant molecular profile. Of the remaining 43 culture-positive cases, molecular profiling identified spatially and temporally related sources in six cases (14.0%). These six children, along with four other children whose source cases were discovered through reverse-contact tracing, had a high morbidity and mortality. The increasing burden of paediatric TB in both foreign-born children and Canadian-born children of foreign-born parents calls for more timely diagnosis of source cases and more targeted screening for latent TB infection. Conventional and molecular epidemiology can inform paediatric TB elimination strategy in high-income countrieshttp://ow.ly/mwbn30iY1WF

Abstract
Tuberculosis (TB) is the most important infectious disease all over the world, with a high morbidity and mortality. Pediatric tuberculosis has been a neglected epidemic, due to the difficulties in assessing its global impact, reduced incidence and lower infectivity compared to adults. In 2015, the WHO reported 1 million cases of paediatric TB and 169,000 deaths. In Europe, the emergence of MDR TB is a major concern, representing 16% of the new diagnosis in Eastern Europe. In 2014, it was estimated that about 219,000 children were infected by MDR-TB-strains in Europe, and 2,120 developed the disease. Spain is the Western European country with more paediatric cases, with an incidence 4.3/100,000 inhabitants in 2014. Paediatric tuberculosis mortality in Spain is rare, but extra-pulmonary disease is associated with significant complications. The prevalence of paediatric drug resistant TB in Spain is over 4%, higher than the estimated incidence in adult population, representing mayor difficulties for therapeutic intervention. These data reveal that paediatric TB is still a Public Health priority in our country. The difficulties in diagnosis and the lack of optimal paediatric drug formulations are the major challenges for controlling the childhood's tuberculosis epidemic. A group of national paeditric TB experts has reviewed the international guidelines and the most recent evidences, and has established new recommendations for the management of paediatric TB contacts, latent infection and active TB disease, especially focused in drug resistant cases. This document replaces the former national guidelines from the Spanish Society for Pediatric Infectios Diseases, although the prior recommendations on the diagnosis remain valid.

Abstract
AIM This study described the epidemiology and clinical features of childhood tuberculosis (TB) in Stockholm over a 45-year period, when there was a resurge of tuberculosis concomitant with increased immigration. METHODS We describe 220 children up to the age of 16 years with active TB, seen at the Astrid Lindgren Children's Hospital from 1971 to 2015. The study period was divided into three 15-year periods. RESULTS Cases increased from ten children in 1971-1985 to 76 in 1986-2000 and 134 in 2001-2015, with overall incidence increasing from <1 to four per 100 000. From 2001 to 2015, 79% of cases, or at least one parent, were born in high-incidence countries. The incidence in this group was 35 per 100 000, but remained at 0.9 per 100 000 in other children. After 2000, most cases were detected by active contact tracing and immigrant screening. The most common manifestation was from the lungs. Meningitis and miliary tuberculosis were found in 7%, with two deaths. Antimicrobial resistance was an increasing problem. CONCLUSION The increasing incidence of TB in Stockholm was largely limited to children with a background in high-incidence countries. Most children today have subclinical forms of TB. Although preventive measures are effective, severe cases still occur, especially among adolescent immigrants.

Abstract
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.

Abstract
Background: Although tuberculosis (TB) incidence has been decreasing in the European Union/European Economic Area (EU/EEA) in the last decades, specific subgroups of the population, such as migrants, remain at high risk of TB. This study is based on the report ‘Key Infectious Diseases in Migrant Populations in the EU/EEA’ commissioned by The European Centre for Disease Prevention and Control. Methods: We collected, critically appraised and summarized the available evidence on the TB burden in migrants in the EU/EEA. Data were collected through: (i) a comprehensive literature review; (ii) analysis of data from The European Surveillance System (TESSy) and (iii) evidence provided by TB experts during an infectious disease workshop in 2012. Results: In 2010, of the 73 996 TB cases notified in the EU/EEA, 25% were of foreign origin. The overall decrease of TB cases observed in recent years has not been reflected in migrant populations. Foreign-born people with TB exhibit different socioeconomic and clinical characteristics than native sufferers. Conclusion: This is one of the first studies to use multiple data sources, including the largest available European database on infectious disease notifications, to assess the burden and provide a comprehensive description and analysis of specific TB features in migrants in the EU/EEA. Strengthened information about health determinants and factors for migrants’ vulnerability is needed to plan, implement and evaluate targeted TB care and control interventions for migrants in the EU/EEA.

Abstract
We prospectively studied the prevalence of imported transmissible diseases in 373 immigrant children and adolescents coming from Sub-Saharan Africa, North Africa and Latin America to Salamanca, Spain. The most frequent transmissible diseases in this group were latent tuberculosis (12.7%), chronic hepatitis B virus infection (4.2%), hepatitis C virus infection (2.3%), syphilis (1.5%) and human T-lymphotropic virus type 1 or 2 infections (1.4%). A total of 24.2% of patients had serologic profiles suggesting past hepatitis B virus infection. Anti-human immunodeficiency virus antibodies were not detected in any subject. Largely asymptomatic immigrant children show a high prevalence of communicable diseases. Thus, infectious disease screenings are highly advisable in immigrant children coming from low-income countries.

Abstract
Our understanding of the tuberculosis (TB) epidemic in children is incomplete due to challenges in diagnosis and reporting. Children have also been largely excluded from research and advocacy. However, the tide appears to be turning and interest in pediatric TB is increasing. In this article, we explore the epidemiology of childhood TB by first reviewing the natural history of TB in children and the factors that impact on each of the stages from exposure to disease. We then discuss how these factors affect what we see at a country and regional level. Finally, we assess the burden of childhood TB globally.

Abstract
Background The occurrence of tuberculosis (TB) among children has long been neglected as a public health concern. However, any child with TB is a sentinel event indicating recent transmission. Vaccination, early case finding and treatment of those latently infected with TB can prevent cases, severe morbidity and unnecessary death. Method The objective of the study was to describe the occurrence of TB events among children in the Netherlands which may be avoided through preventive measures. For this purpose we performed a trend analysis of routine Dutch TB and LTBI (surveillance data in 1993–2012 and a descriptive analysis of children with TB and with LTBI diagnosed in 2005–2012). Results Overall childhood TB incidence has declined over the last two decades from 3.6 in 1993 to 1.9 per 100,000 children in 2012. The decline was stronger among Dutch-born children compared to foreign-born children. In 2005–2012 64% of childhood TB cases were detected through active case finding. Foreign-born children with TB were less likely to be detected through active case finding, when not detected through post-entry TB screening. Childhood TB diagnosis was culture confirmed in 68% of passively detected cases and 12% of actively detected cases. Of 1,049 children with LTBI started on preventive treatment in 2005–2012, 90% completed treatment. In 37% of all childhood TB cases there was at least one ‘missed opportunity’ for prevention. Thirty nine percent of child TB patients eligible for BCG were not vaccinated. Conclusion Children with TB in the Netherlands are generally detected at an early stage and treatment completion rates are high. However, more TB cases among children can be prevented through enhancing TB case finding and screening and preventive treatment of latent TB infection among migrant children, and improving the coverage of BCG vaccination among eligible risk groups.

Abstract
BACKGROUND Multidrug-resistant tuberculosis threatens to reverse recent reductions in global tuberculosis incidence. Although children younger than 15 years constitute more than 25% of the worldwide population, the global incidence of multidrug-resistant tuberculosis disease in children has never been quantified. We aimed to estimate the regional and global annual incidence of multidrug-resistant tuberculosis in children. METHODS We developed two models: one to estimate the setting-specific risk of multidrug-resistant tuberculosis among child cases of tuberculosis, and a second to estimate the setting-specific incidence of tuberculosis disease in children. The model for risk of multidrug-resistant tuberculosis among children with tuberculosis needed a systematic literature review. We multiplied the setting-specific estimates of multidrug-resistant tuberculosis risk and tuberculosis incidence to estimate regional and global incidence of multidrug-resistant tuberculosis disease in children in 2010. FINDINGS We identified 3403 papers, of which 97 studies met inclusion criteria for the systematic review of risk of multidrug-resistant tuberculosis. 31 studies reported the risk of multidrug-resistant tuberculosis in both children and treatment-naive adults with tuberculosis and were used for evaluation of the linear association between multidrug-resistant disease risk in these two patient groups. We identified that the setting-specific risk of multidrug-resistant tuberculosis was nearly identical in children and treatment-naive adults with tuberculosis, consistent with the assertion that multidrug-resistant disease in both groups reflects the local risk of transmitted multidrug-resistant tuberculosis. After application of these calculated risks, we estimated that around 999,792 (95% CI 937,877-1,055,414) children developed tuberculosis disease in 2010, of whom 31,948 (25,594-38,663) had multidrug-resistant disease. INTERPRETATION Our estimates underscore that many cases of tuberculosis and multidrug-resistant tuberculosis disease are not being detected in children. Future estimates can be refined as more and better tuberculosis data and new diagnostic instruments become available.

Abstract
INTRODUCTION The National Hospital Discharge Registry is a clinical-administrative database on hospital discharges, which is very useful at a regional level as a complementary source for surveillance. There are few national studies on tuberculosis (TB) using the National Hospital Discharge Registry, thus it was considered of interest to study the characteristics and trends of hospital discharges for TB in Spain. METHODS A descriptive study was performed using the main variables in the National Hospital Discharge Registry (sex, age, main diagnosis, type of discharge, length of stay), and trend analysis of hospitalization rates per 100,000 population, as well as primary diagnosis, by sex, age group, and type of TB (pulmonary [TBP]/extrapulmonary [TBEP]), for the period 1999-2009 in Spain. RESULTS A total of 65,609 hospital discharges were included in the study (66% male, 66% TBP, and 52% between 15-44 years). The overall rate of TB for the entire hospitalization period was 13.93 per 100,000 inhabitants, being 18.83 in males and 9.18 in females. The hospitalization rates for TBP and TBEP decreased in the period 1999-2009 in both sexes (TBP in males, from 18 to 13, and in females, from 8 to 6; TBEP in males from 4 to 3, and from 3 to 2 in female hospitalizations/100,000 habitants). In TBP, children are those with a smallest decline, and in TBEP there is an increase in males in all age groups from 2005. CONCLUSIONS The results are consistent with those from surveillance. The slow decline in rates in children and the increase in extrapulmonary forms in males may be related to immigration, so it is necessary to improve TB monitoring in these groups.

Abstract
BACKGROUND The rates of isoniazid (INH) and multidrug-resistant (MDR) tuberculosis (TB) among European children vary between 10.4% and 3.5%. Spain is a low endemic country with reported rates of 4.9% of INH resistance and 1.3% of MDR in adults. However, data regarding patterns of TB resistance in children are scarce. Our aim is to determine the incidence and risk factors for pediatric-resistant TB in our setting to help developing age-targeted guidelines. METHODS A multicenter, retrospective study including 22 hospitals from Madrid region (EREMITA study group) was performed from January 2005 to June 2010. Medical records from children diagnosed with TB were reviewed for demographic characteristics, clinical presentation and outcomes. Risk factors for INH and MDR TB were identified. RESULTS Of 396 children diagnosed with TB, 72.4% were born to foreign parents. Microbiologic confirmation by culture (n = 200) or PCR (n = 8) was documented in 208 children (52.5%). Drug susceptibility results were available in 188 children: 9.6% (n = 18) were resistant to INH and 3.1% (n = 6) were MDR. INH resistance was more common in immigrants compared with native families (11.9% vs. 0%; P = 0.013), as was also MDR (4.5% vs. 0%; P = 0.34). Extrapulmonary TB and previous antituberculous treatment were significantly associated with INH and MDR, while immunosuppression was associated only with MDR. CONCLUSIONS The rates of INH and MDR TB were different according to the parents' origin, with higher rates among children born to foreign parents. Local surveillance of drug-resistant TB is critical to develop appropriate guidelines for treatment.

Abstract
Data from 484 children (median age: 6 years; 46.5% immigrants) hospitalized for tuberculosis in 31 Tuscan hospitals in 1997-2011 were analyzed. Incidence increased from 7.3 (95% confidence interval: 4.9-9.4) to 12.5 (95% confidence interval: 9.6-15.4) per 100,000 (P=0.009). Increases were particularly profound in children<5 years of age, reaching 13.3 (95% confidence interval: 7.8-18.9; P<0.0001 for 2011 vs.1997) per 100,000. Pediatric tuberculosis is a major issue in Tuscany.

Abstract
BACKGROUND Isoniazid resistance is an obstacle to the treatment of tuberculosis disease and latent tuberculosis infection in children. We aim to summarize the literature describing the risk of isoniazid-resistant tuberculosis among children with tuberculosis disease. METHODS We did a systematic review of published reports of children with tuberculosis disease who had isolates tested for susceptibility to isoniazid. We searched PubMed, Embase and LILACS online databases up to January 12, 2012. RESULTS Our search identified 3403 citations, of which 95 studies met inclusion criteria. These studies evaluated 8351 children with tuberculosis disease for resistance to isoniazid. The median proportion of children found to have isoniazid-resistant strains was 8%; the distribution was right-skewed (25th percentile: 0% and 75th percentile: 18%). CONCLUSIONS High proportions of isoniazid resistance among pediatric tuberculosis patients have been reported in many settings suggesting that diagnostics detecting only rifampin resistance are insufficient to guide appropriate treatment in this population. Many children are likely receiving substandard tuberculosis treatment with empirical isoniazid-based regimens, and treating latent tuberculosis infection with isoniazid may not be effective in large numbers of children. Work is needed urgently to identify effective regimens for the treatment of children sick with or exposed to isoniazid-resistant tuberculosis and to better understand the scope of this problem.

Abstract
BACKGROUND Tuberculosis (TB) is among the top 10 causes of child death worldwide. Nevertheless, childhood disease has been neglected by tuberculosis control programs. METHODS This was a retrospective study of patients < 16 years of age diagnosed with active TB in 2 tertiary hospitals in Rome (Italy), between 1990 and 2009. RESULTS Two hundred fourteen cases of active tuberculosis were identified (132 definite, 82 probable). Pulmonary involvement was the most common form (75.5%), followed by lymphadenopathy (15.4%) and central nervous system TB (11%). Fever (51.86%) and cough (40%) were the most common presenting symptoms. A total of 23.4% of children were asymptomatic on admission. Sensitivities of the tuberculin skin test and the quantiferon test were 93.4% and 97%, respectively. Both tests performed in 52 children agreed in 49 cases (94%). Sensitivities for culture, Ziehl-Neelsen staining and polymerase chain reaction were 58%, 25% and 66.3%, respectively. The adult source case was identified in 28% of cases. History of contact with a patient with active TB was associated with pulmonary TB (P = 0.0014), whereas negative history of contact was associated with lymph node (P = 0.0064) and central nervous system TB (P = 0.05). CONCLUSIONS Our study emphasizes the difficulty in managing children with suspected TB, because the absence of constitutional symptoms cannot exclude TB, and bacteriologic confirmation is the exception. Immunologic diagnosis can be a valuable tool to identify TB-infected children because the quantiferon test showed high sensitivity in all age groups. This is of primary importance because early identification of children with latent tuberculous infection and appropriate chemoprophylaxis represent, to date, the most important tool to reduce the burden of TB.

Abstract
BACKGROUND Increasing international migration has changed the epidemiology of tuberculosis (TB) in Europe. Little is published on clinical manifestations and epidemiology in children in this new era. METHODS Clinical and laboratory data on all children with TB in Stockholm between 2000 and 2009 were entered into a database and retrospectively completed with information from case records. Population data, including parents' country of birth, were obtained from Statistics Sweden. RESULTS TB was diagnosed in 147 children <18 years of age (78 confirmed, 12 probable, 57 possible). Fifty-six children (38%) presented clinically, and 91 were identified by screening procedures. Ninety children (61%) were born in high-endemic countries and 38 in Sweden to parents from such countries. The incidence was 451/100,000 person years among children born in Somalia, 44 among those born in other high-endemic countries, and 13 among Swedish-born children with parents from high-endemic countries. All but 1 of the 19 Swedish-born children with Swedish parents belonged to a single outbreak. Median age was 12 years. Severe, adult-type TB was predominantly observed in adolescents, whereas young children presented mild, primary disease that was diagnosed at the time of screening. The 78 positive cultures were traced back to 67 strains. Resistance to any first-line drug was present in 25% of the strains, of which 4 were multidrug resistant. CONCLUSIONS Active TB in Stockholm is common in children born in high-endemic countries, especially Somalia. The most severe cases are seen in adolescents. The high prevalence of antimicrobial resistance is a cause for concern.
