Understanding and controlling asthma in Latin America: A review of recent research informed by the SCAALA programme. Clin Transl Allergy 2023; 13:e12232. [PMID: 36973960 PMCID: PMC10041090 DOI: 10.1002/clt2.12232] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2022] [Revised: 02/01/2023] [Accepted: 02/15/2023] [Indexed: 03/29/2023] Open
Abstract
Asthma is an important health concern in Latin America (LA) where it is associated with variable prevalence and disease burden between countries. High prevalence and morbidity have been observed in some regions, particularly marginalized urban populations. Research over the past 10 years from LA has shown that childhood disease is primarily non-atopic. The attenuation of atopy may be explained by enhanced immune regulation induced by intense exposures to environmental factors such as childhood infections and poor environmental conditions of the urban poor. Non-atopic symptoms are associated with environmental and lifestyle factors including poor living conditions, respiratory infections, psychosocial stress, obesity, and a diet of highly processed foods. Ancestry (particularly African) and genetic factors increase asthma risk, and some of these factors may be specific to LA settings. Asthma in LA tends to be poorly controlled and depends on access to health care and medications. There is a need to improve management and access to medication through primary health care. Future research should consider the heterogeneity of asthma to identify relevant endotypes and underlying causes. The outcome of such research will need to focus on implementable strategies relevant to populations living in resource-poor settings where the disease burden is greatest.

Abstract
A growing body of evidence suggests a potential link between child maltreatment and asthma. Determining whether and how child maltreatment causes or worsens asthma would have major implications for disease prevention and treatment, as well as public health policy. In this article, we examine epidemiologic studies of child maltreatment and asthma and asthma-related outcomes, review the evidence for potential mechanisms underlying the child maltreatment-asthma association, and discuss future directions. To date, a child maltreatment-asthma link has been reported in most studies of children and adults, though the type of maltreatment associated with asthma has differed across studies. Such discrepant findings are likely explained by differences in study design and quality. All studies have been limited by potential under-reporting of child maltreatment and selection bias, and nonthorough assessment of asthma. Despite these limitations, the aggregate evidence from epidemiologic studies suggests a possible causal link between child maltreatment and asthma, though the relative contributions of various types of maltreatment (physical, sexual, emotional, or neglect) are unclear. To date, there is insufficient evidence of an association between child maltreatment and lung function in children or adults. Limited evidence further suggests that child maltreatment could influence the development or severity of asthma through direct effects on stress responses and anxiety- or depressive-related disorders, immunity, and airway inflammation, as well as indirect effects such as increased obesity risk. Future prospective studies should aim to adequately characterize both child maltreatment and asthma, while also assessing relevant covariates and biomarkers of stress, immune, and therapeutic responses.

Adulthood asthma as a consequence of childhood adversity: a systematic review of epigenetically affected genes. J Dev Orig Health Dis 2022; 13:674-682.

Abstract
There is an accumulating data that shows relation between childhood adversity and vulnerability to chronic diseases as well as epigenetic influences that in turn give rise to these diseases. Asthma is one of the chronic diseases that is influenced from genetic regulation of the inflammatory biomolecules and therefore the hypothesis in this research was childhood adversity might have caused epigenetic differentiation in the asthma-related genes in the population who had childhood trauma. To test this hypothesis, the literature was systematically reviewed to extract epigenetically modified gene data of the adults who had childhood adversity, and affected genes were further evaluated for their association with asthma. PRISMA guidelines were adopted and PubMed and Google Scholar were included in the searched databases, to evaluate epigenetic modifications in asthma-related genes of physically, emotionally or sexually abused children. After retrieving a total of 5245 articles, 36 of them were included in the study. Several genes and pathways that may contribute to pathogenesis of asthma development, increased inflammation, or response to asthma treatment were found epigenetically affected by childhood traumas. Childhood adversity, causing epigenetic changes in DNA, may lead to asthma development or influence the course of the disease and therefore should be taken into account for the prolonged health consequences.

Abstract
BACKGROUND Little is known about the risk factors for atopic and nonatopic asthma among children in Puerto Rico. We aimed to identify modifiable risk factors for atopic and nonatopic asthma in this vulnerable population. METHODS Case-control study of children with (n = 305) and without (n = 327) asthma in San Juan (Puerto Rico). Asthma was defined as physician-diagnosed asthma and wheeze in the previous year. Atopic asthma (n = 210) was defined as asthma and greater than or equal to one positive IgE to aero-allergens. Nonatopic asthma (n = 95) was defined as asthma and no positive IgE to the allergens tested. Logistic regression was used for the multivariable analysis of atopic and nonatopic asthma. RESULTS In a multivariable analysis, body mass index (BMI) z score, prematurity, parental asthma, lifetime exposure to gun violence, and having a bird in the child's home were associated with increased odds of atopic asthma, while each one-point increment in a dietary score (range: -2 [least healthy diet] to +2 [healthiest diet]) was associated with 37% reduced odds of atopic asthma (95% confidence interval [CI] = 0.48-0.81; P < .01). In a separate multivariable analysis, parental asthma, early-life second-hand smoke (SHS) exposure, and daycare attendance in the first year of life were significantly associated with increased odds of nonatopic asthma, while each one-point increment in the dietary score was associated with 42% reduced odds of nonatopic asthma (95% CI = 0.45-0.76; P < .01). CONCLUSIONS We have identified potentially modifiable risk factors for atopic asthma (eg, BMI and gun violence), nonatopic asthma (eg, early-life SHS and daycare attendance), or both (eg, an unhealthy diet) in Puerto Rican children.

Abstract
OBJECTIVE First, to review and critically discuss published evidence on psychosocial stressors, stress, and asthma in adolescents and, then, discuss potential future directions in this field. DATA SOURCES The data source is the National Library of Medicine (PubMed database). STUDY SELECTIONS A literature search was conducted for human studies on stressors or stress and asthma between 2000 and 2020. Studies that were published in English, contained a full text, and included adolescents were considered for inclusion in this review. RESULTS Compared with the available body of evidence in children and adults, relatively few studies have been published in adolescents. Current evidence suggests that exposure to stressors (at the individual, family, and community levels) or stress (acute and chronic) is associated with asthma and worse asthma outcomes, but such evidence must be cautiously interpreted owing to limitations in the design or the analytical approach of the published studies. CONCLUSION Future large studies with a prospective design should determine whether and how stressors or stress causes or worsens asthma in adolescents. At present, clinicians should assess exposure to stressors (eg, violence or abuse) and screen for anxiety and depressive disorders when caring for adolescents with asthma in addition to providing referrals to social workers or mental health professionals when appropriate. Public health policies are needed to reduce psychosocial stressors, such as gun violence and racism, in adolescents.

Abstract
OBJECTIVES An increased asthma prevalence was found in cleaners. Many of them work in precarious employment conditions, potentially leading to stress, a known risk factor for asthma. We aimed to analyze whether asthma in cleaners might partly be explained by psychosocial working conditions. METHODS The study population of this cross-sectional study included 199 cleaners employed at regional public health services in Puno Province (Peru). They were compared to 79 unexposed workers from Lima, Peru (response 83%). Both groups answered the short version of the European Working Condition Survey and a modified version of the European Community Respiratory Health screening questionnaire. After multiple imputation, the association between psychosocial working conditions and asthma (wheeze without cold or use of asthma medication) was assessed. RESULTS The 12-months prevalence of asthma was 22% among cleaners versus 5% among unexposed workers (pChi(2) = .001). Cleaners were more likely than unexposed workers to work with temporary or sub-contracts, have a high employment insecurity, high strain working conditions and low social support (all pChi(2) < .05). Twenty-six percent vs. 10% reported a high bullying score; 39% vs. 8% had experienced violence at work (both pChi(2) < .001). High bullying score (adjusted Odds Ratio 5.6; 95% Confidence Interval 1.5-21.4) and violence (2.4; 1.1-5.4) were the main predictors of asthma. Taking these factors into account, being a cleaner was not statistically significantly associated with the outcome (3.5; 0.9-13.8). CONCLUSIONS Poor psychosocial working conditions of cleaners may partly explain the high prevalence of asthma. The underlying mechanism might be a stress-induced inflammatory immune response.

Abstract
BACKGROUND Child maltreatment is a common problem with known adverse consequences, yet its contributions to the development and course of pediatric asthma are only poorly understood. MAIN This review first describes possible pathways connecting child maltreatment to pediatric asthma, including aspects of the physical home environment, health behaviors and disease management, and psychological consequences of child maltreatment. We subsequently review existing studies, which generally report an association between maltreatment experiences and asthma outcomes in childhood. However, this literature is in its early stages; there are only a handful studies, most of them rely on self-reports of both child maltreatment and asthma history, and none have investigated the physiological underpinnings of this association. Taken together, however, the studies are suggestive of child maltreatment playing a role in pediatric asthma incidence and expression that should be explored further. CONCLUSION Existing data are sparse and do not allow for specific conclusions. However, the data are suggestive of child maltreatment influencing asthma risk and morbidity long before the adult years. Future research should focus on understanding how child maltreatment contributes to asthma disease risk and progression in this highly vulnerable population.
