Asthma, Eczema, and Food Allergy in Children Following Liver Transplantation.

OBJECTIVES: To describe the prevalence and the relationship between asthma, eczema, food allergy, and rhinitis in children after liver transplantation. STUDY DESIGN: Children who were liver transplant recipients were investigated to assess whether the high prevalence of food allergies was accompanied by eczema, rhinitis, and asthma. Furthermore, we included 56 children with chronic liver disease to explore the risk of allergy, eczema, and asthma in this group. RESULTS: After liver transplantation, children had higher prevalence of allergic reactions to food as compared with children with chronic liver disease (P < .001). Current asthma (P = .04) and eczema (P < .02) were observed more frequently in transplanted children as compared with children with chronic liver disease. For transplanted children who had ever received tacrolimus the relative risk (RR) of asthma was 1.7 (95% CI, 1.2-2.4; P = .02) as compared with children with chronic liver disease. Transplanted children with asthma had higher rates of sensitization to food allergens than those without asthma (RR, 3.6; 95% CI, 1.3-10.3; P = .01). The most frequent food allergens associated with asthma in transplanted children were milk (RR for asthma, 3.9; 95% CI, 1.6-9.4; P < .01), eggs (RR, 2.9; 95% CI, 1.2-7.0; P = .03), and peanuts (RR, 3.7; 95% CI, 1.6-8.3; P < .01). Food allergies occurred earlier than asthma, at 1.5 years after transplantation (IQR, 0.5-3.0 years) vs 2.5 years after transplantation (IQR, 1.0-4.5 years; P < .05). Food allergies were also associated with eczema, but not with sensitization to aero-allergens or rhinitis. CONCLUSIONS: The high risk of food allergies in children who were liver transplant recipients was associated with eczema and asthma, but not rhinitis. The most frequent food allergens associated with asthma were milk, eggs, and peanuts.

Respiratory Health Outcomes, Rhinitis, and Eczema in Workers from Grain Storage Facilities in Costa Rica.

Objectives: To examine the associations of inhalable grain dust exposure with respiratory health outcomes, rhinitis, and eczema reported by workers from rice, wheat, and maize storage facilities. Methods: A cross-sectional study of 136 workers (73 operators and 63 administrative staff and other workers) from eight Costa Rican grain storage facilities was conducted in 2014-2015. Full-shift personal inhalable dust samples from all workers were collected. Study participants were administered a short version of the European Community Respiratory Health Survey questionnaire to identify symptoms of asthma, chronic bronchitis, rhinitis, and eczema. Associations between grain dust exposure and health outcomes were assessed using multivariable logistic and negative binomial regression models adjusted for age, smoking history, grain type, and presence of pets or farm animals in the home. Results: The median inhalable grain dust concentration was 2.0 (25th to 75th percentile: 0.3-7.0) mg m-3. Higher concentrations of inhalable dust were associated with increased odds of (i) asthma symptoms or medication use [adjusted Odds ratio (ORa) per 10-fold increase in dust concentration 2.7; 95% confidence interval (CI): 1.3-6.7]; (ii) a score of at least two out of five symptoms suggestive of asthma (ORa 1.2; 95% CI: 1.0-1.3); and (iii) eczema (ORa 3.6; 95% CI: 1.7-9.6). No associations of inhalable grain dust exposure with chronic bronchitis and rhinitis were observed. Conclusions: High exposure to inhalable dust in Costa Rican grain storage facilities was associated to asthma symptoms and eczema in workers.

Síndrome hiper IGE: a propósito de tres casos clínicos / Hyper IGE syndrome: three case reports

Introducción: El síndrome Hiper IgE (SHIGE) autosómico dominante (SHIGE-AD) es una inmunodeficiencia primaria asociada a alteraciones del tejido conectivo, esqueléticas, cerebrales y vasculares. La patogénesis de la inmunodeficiencia reside en una alteración en la vía Th17 lo que explica la susceptibilidad especial de estos pacientes a infecciones por S. aureus y Candida. Objetivo: Describir tres niños diagnosticados como síndrome Hiper IgE y realizar una revisión sobre el tema, con especial foco en la forma dominante de la enfermedad. Casos clínicos: Se presentan 3 niños con SHIGE (2 varones), con rash eccematoso desde el período de recién nacido, infecciones cutáneas, óticas, pulmonares, ganglionares, con niveles de IgE sérica sobre 2.000 UI/ml y eosinofilia, tratados con antimicrobianos y tópicos, con seguimiento más de 7 años. Conclusiones: Es una entidad infrecuente, que requiere alto grado de sospecha y el manejo precoz de las infecciones. Uno de sus principales diagnósticos diferenciales está dado por el niño atópico con infecciones recurrentes pero difieren en el contexto, respuesta y resolución frente a las infecciones y la falta de las otras características fenotípicas.

Introduction: Autosomal dominant Hyper IgE syndrome (HIES-AD) is a primary immunodeficiency associated with connective tissue, skeletal, vascular and brain disorders. The pathogenesis of immune deficiency lies in an alteration of Th17 cells which explains the special susceptibility of these patients to S. aureus and Candida infections. Objective: To describe three children diagnosed with hyper IgE syndrome and conduct a study on the subject, with special focus on the dominant form of the disease. Case reports: 3 children with HIES-AD (2 males and one female) with eczema since birth, skin, ear, lung, and lymph node infections, and serum IgE levels over 2,000 IU/ml and eosinophilia values, treated with antibiotics and topically, and 7 year follow-up. Conclusions: It is a rare condition that requires a high index of suspicion and early management of infections. One of its main diagnoses is atopic syndrome with recurrent infections but both conditions differ in context, response and resolution against infections and lack of other phenotypic characteristics.

Risk factors for eczema in infants born in Cuba: a population-based cross-sectional study.

BACKGROUND: There is a concern that allergic disease in childhood is higher than expected in Cuba. The aim of this study was to determine the risk factors for eczema of infants aged 12-15 months living in Havana. METHODS: We used a cross-sectional epidemiological study design. Data on eczema symptoms and a wide range of lifestyle factors were collected by researcher administered questionnaires. RESULTS: Data were collected on 1956 children (96% response rate), of whom 672 (34%) were reported as having had eczema. Independent risk factors for eczema included young maternal age (adjusted odds ratio (OR) 0.98 per additional year of age; 95% confidence interval (CI) 0.97-0.99), child's weight (OR 1.13 per additional kg; 95% CI: 1.03-1.25), insect sting allergy (OR 2.11; 95% CI: 1.33-3.35), rodents in the home (OR 1.39; 95% CI: 1.10-1.76), attendance at childcare facilities (OR 1.34: 95% CI: 1.05-1.70) and self-reported mould in the home (OR 1.23; 95% CI: 1.07-1.41). Infant exposure to paracetamol was associated with an increased risk of eczema even after adjustment for wheeze (OR 1.22; 95% CI: 1.03-1.46). CONCLUSION: Despite a very different culture and environment, the consistency of these findings with those from more economically developed countries suggests potential causal associations. The association with paracetamol, even after adjustment for wheeze, suggests that intervention studies are required in young infants, to ascertain if this commonly used anti-pyretic medication increases allergic disease.

Association between environmental factors and current asthma, rhinoconjunctivitis and eczema symptoms in school-aged children from Oropeza Province--Bolivia: a cross-sectional study.

BACKGROUND: In recent years, the prevalence of asthma, rhinoconjunctivitis and eczema symptoms in childhood has considerably increased in developing countries including Bolivia, possibly due to changes in lifestyle, environmental and domestic factors. This study aimed to assess the association between environmental factors and asthma, rhinoconjuctivitis and eczema symptoms in school-aged children from Oropeza Province in Chuquisaca, Bolivia. METHODS: A cross-sectional study was performed in 2340 children attending the fifth grade in 36 randomly selected elementary schools in Oropeza province. The prevalence of symptoms was determined using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Environmental factors were assessed by the ISAAC environmental questionnaire including questions related to exposure to pets, farm animals, indoor and outdoor pollution, presence of disease vectors at home and precarious household conditions. Generalized linear mixed-effects models were adjusted for age, sex and place of living. RESULTS: Thirty seven percent of children reported that at least one of their parents smoked at home. Wood or coal was used as cooking fuel in 19% of the homes and 29% reported intense truck traffic on the street where they lived. With respect to hygiene conditions, 86% reported exposure to dogs, 59% exposure to cats and 36% regular contact to farm animals. More than one precarious household condition was reported by 8% of children. In the adjusted model exposure to dog (adjusted OR 1.4; CI 95% 1.0-1.9), cat (1.2; 1.0-1.5), farm animals (1.5; 1.2-1.8); intense truck traffic (1.3; 1.0-1.6), parents smoking at home (1.2; 1.0-1.5), presence of disease vectors at home (fourth quartile vs. first quartile: 1.6; 1.2-2.3) and two or more precarious household conditions (1.5; 1.0-2.2) were significantly associated with rhinoconjunctivitis symptoms. The associations were similar for asthma and eczema symptoms; however it did not reach the level of statistical significance for all items. CONCLUSION: Our results support previous findings reported for poor communities especially in Latin America, showing that lower hygiene conditions did not have protective effect against asthma and rhinoconjunctivitis and eczema symptoms.

Cutaneous manifestations in patients with Wiskott-Aldrich syndrome submitted to haematopoietic stem cell transplantation.

INTRODUCTION: Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency caused by a mutation of the WAS protein gene. This protein actively participates in important cellular processes, and its presence is related to diverse clinical manifestations, including cutaneous alterations. The classical triad of WAS consists of recurrent infections, thrombocytopaenia with small platelets and atopic dermatitis (AD)-like lesions. OBJECTIVE: To evaluate the frequencies of cutaneous manifestations in patients with WAS prior to haematopoietic stem cell transplantation (HSCT). RESULTS: Twenty-four boys diagnosed with WAS and treated with HSCT between 1992 and 2007 were included. The characteristic triad of WAS occurred in 46% of patients. Before HSCT, the most frequent cutaneous manifestations included eczema similar to AD (71%), followed by petechiae and/or ecchymosis (58%) and cutaneous infections (17%). CONCLUSIONS: Cutaneous manifestations in patients with WAS are frequent, especially those similar to the eczema found in AD.

Use of antibiotics during pregnancy increases the risk of asthma in early childhood.

OBJECTIVES: To investigate the hypothesis that mother's use of antibiotics in pregnancy could influence asthma and eczema in early life. STUDY DESIGN: Subjects were included from the Copenhagen Prospective Study on Asthma in Childhood cohort of children born of mothers with asthma (N = 411). Severe asthma exacerbations and eczema were diagnosed by research unit physicians. Replication was sought in children from the Danish National Birth Cohort (N = 30 675). Asthma outcomes were hospitalization and use of inhaled corticosteroids. Eczema was defined by an algorithm developed from cases of clinically verified eczema. All children were followed to age 5 years in a cohort study design. RESULTS: The Copenhagen Prospective Study on Asthma in Childhood data showed increased risk of asthma exacerbation (hazard ratio 1.98 [95% CI 1.08-3.63]) if mothers had used antibiotics during third trimester. The Danish National Birth Cohort confirmed increased risk of asthma hospitalization (hazard ratio 1.17 [1.00-1.36]), and inhaled corticosteroids (1.18 [1.10-1.27]) in the children if mothers used antibiotics any time during pregnancy. In the subgroup of mothers using antibiotics for nonrespiratory infection, the children also had increased risk of asthma. CONCLUSION: We found increased risk of asthma associated with maternal antibiotic use in a clinical study of a birth cohort with increased risk of asthma and replicated this finding in an unselected national birth cohort, and in a subgroup using antibiotics for nonrespiratory infections. This supports a role for bacterial ecology in pre- or perinatal life for the development of asthma.

Particular characteristics of allergic symptoms in tropical environments: follow up to 24 months in the FRAAT birth cohort study.

BACKGROUND: Early wheezing and asthma are relevant health problems in the tropics. Mite sensitization is an important risk factor, but the roles of others, inherent in poverty, are unknown. We designed a birth-cohort study in Cartagena (Colombia) to investigate genetic and environmental risk factors for asthma and atopy, considering as particular features perennial exposure to mites, parasite infections and poor living conditions. METHODS: Pregnant women representative of the low-income suburbs of the city were randomly screened for eligibility at delivery; 326 mother-infant pairs were included at baseline and biological samples were collected from birth to 24 months for immunological testing, molecular genetics and gene expression analysis. Pre and post-natal information was collected using questionnaires. RESULTS: 94% of families were from the poorest communes of the city, 40% lacked sewage and 11% tap-water. Intestinal parasites were found as early as 3 months; by the second year, 37.9% of children have had parasites and 5.22% detectable eggs of Ascaris lumbricoides in stools (Median 3458 epg, IQR 975-9256). The prevalence of "wheezing ever" was 17.5% at 6 months, 31.1% at 12 months and 38.3% at 24 months; and recurrent wheezing (3 or more episodes) 7.1% at 12 months and 14.2% at 24 months. Maternal rhinitis [aOR 3.03 (95%CI 1.60-5.74), p = 0.001] and male gender [aOR 2.09 (95%CI 1.09 - 4.01), p = 0.026], increased risk for wheezing at 6 months. At 24 months, maternal asthma was the main predisposing factor for wheezing [aOR 3.65 (95%CI 1.23-10.8), p = 0.01]. Clinical symptoms of milk/egg allergy or other food-induced allergies were scarce (1.8%) and no case of atopic eczema was observed. CONCLUSIONS: Wheezing is the most frequent phenotype during the first 24 months of life and is strongly associated with maternal asthma. At 24 months, the natural history of allergic symptoms is different to the "atopic march" described in some industrialized countries. This cohort is representative of socially deprived urban areas of underdeveloped tropical countries. The collection of biological samples, data on exposure and defined phenotypes, will contribute to understand the gene/environment interactions leading to allergy inception and evolution.

Risk factors and immunological pathways for asthma and other allergic diseases in children: background and methodology of a longitudinal study in a large urban center in Northeastern Brazil (Salvador-SCAALA study).

BACKGROUND: The prevalence of asthma and allergic diseases has increased in industrialised countries, and it is known that rates vary according whether the area is urban or rural and to socio-economic status. Surveys conducted in some urban settings in Latin America found high prevalence rates, only exceeded by the rates observed in industrialised English-speaking countries. It is likely that the marked changes in the environment, life style and living conditions in Latin America are responsible for these observations. The understanding of the epidemiological and immunological changes that underlie the increase in asthma and allergic diseases in Latin America aimed by SCAALA studies in Brazil and Ecuador will be crucial for the identification of novel preventive interventions. METHODS/DESIGN: The Salvador-SCAALA project described here is a longitudinal study involving children aged 4-11 years living in the city of Salvador, Northeastern Brazil. Data on asthma and allergic diseases (rhinitis and eczema) and potential risk factors will be collected in successive surveys using standardised questionnaire. This will be completed with data on dust collection (to dust mite and endotoxin), skin test to most common allergens, stool examinations to helminth and parasites, blood samples (to infection, total and specific IgE, and immunological makers), formaldehyde, physical inspection to diagnoses of eczema, and anthropometric measures. Data on earlier exposures when these children were 0-3 years old are available from a different project. DISCUSSION: It is expected that knowledge generated may help identify public health interventions that may enable countries in LA to enjoy the benefits of a "modern" lifestyle while avoiding--or minimising--increases in morbidity caused by asthma and allergies.

A cohort study of health effects of human T-cell lymphotropic virus type I infection in Jamaican children.

OBJECTIVE: Human T-cell lymphotropic virus type I (HTLV-I) infection in childhood is believed to play an important role in risk for adult T-cell leukemia/lymphoma. Although HTLV-I is known to be associated with infective dermatitis in childhood, other HTLV-I-associated morbidity in children has not been well studied. We sought to determine the HTLV-I-associated health effects in Jamaican children. METHODS: We compared incidence rates of several health outcomes in 28 HTLV-I-infected and 280 uninfected children clinically followed from age 6 weeks to a maximum of 10 years. Cox proportional hazards regression analysis was used to analyze these prospectively collected data, adjusting for confounding effects of other variables as necessary. RESULTS: HTLV-I-infected children had significantly higher incidence rates of seborrheic dermatitis (rate ratio [RR] = 4.8, 95% confidence interval [CI] = 1.9-12.5), eczema (RR = 3.1, CI = 1.2-7.9) and persistent hyperreflexia (RR = 3.7, CI = 1.6-8.2). Additionally, HTLV-I infected children had increased rates of severe anemia (RR = 2.5, CI = 0.8-7.9) and abnormal lymphocytes (RR = 2.4, CI = 0.8-7.6) that were of borderline statistical significance. CONCLUSIONS: Our study suggests that HTLV-I-associated skin diseases of childhood may include seborrheic dermatitis and eczema. Additionally, these data suggest that persistent hyperreflexia of the lower limbs may be an early sign of HTLV-I-associated neurologic involvement in children. Expansion and continued clinical observation of this cohort would be valuable.

Cutaneous manifestations of hyper-IgE syndrome in infants and children.

We describe 8 children with hyper-IgE syndrome who had papulopustular eruption on the face and scalp in the first year of life. Seven of the 8 patients had persistent peripheral eosinophilia and 3 had leukocytosis noted before diagnosis. Skin biopsy specimens in 6 patients revealed spongiosis and perivascular dermatitis and/or folliculitis with a predominance of eosinophils. Two patients had bone fractures and osteopenia. Recurrent pneumonia occurred in 6 children and pneumatoceles in 5. The diagnosis of hyper-IgE syndrome was made an average of 18 months after the onset of the initial papulopustular eruption. These findings may lead to earlier recognition of the disease and institution of appropriate treatment.

Hand eczema: evaluation of 250 patients.

BACKGROUND: Hand eczema (HE) is a chronic multifactorial dermatosis with the presence of endogenous and exogenous factors in its pathogenesis. The etiologic diagnosis of hand eczema is often difficult. OBJECTIVES: The objectives of this study were (1) to detect clinical history and clinical examination data capable of differentiating HE types; (2) to determine the importance of patch tests for the etiologic diagnosis of HE; and (3) on the basis of the definitive diagnosis of HE type with the aid of patch tests, to obtain relevant data for appropriate patient guidance for the control of HE. METHODS: A total of 250 patients with HE were studied over a period of 3 years (1993 to 1995). All patients were submitted to the battery of patch tests. RESULTS AND CONCLUSIONS: The results obtained led to the following conclusions: (1) Women are more predisposed to HE. (2) Work under moist conditions favors HE. (3) With respect to the regional location of HE, any region may be involved in any type of HE; however, involvement of the dorsal region is more common in allergic contact dermatitis (ACD), followed by contact dermatitis owing to primary irritation (ICD) and atopic dermatitis (AD). Location of HE on the dorsal surface of the fingers was mainly observed in ACD, followed by ICD and AD. (4) Patch tests should be part of the investigative routine of HE etiology. (5) The presence of allergy to metals in the clinical history of the patient is a relevant feature, because patch tests confirmed sensitization to nickel in 89% of cases. (6) Rubber components have high sensitization frequency in patients with HE. (7) When the patient reports worsening of HE after the use of rubber gloves, this indicates a probable sensitization to rubber components, mainly in patients with AD.

Dermatitis microbiana numular / Nummular microbial dermatitis

Introducción. La dermatitis microbiana numular (DMN) se ha reportado en México con una frecuencia de 0.5 a 6 por ciento de la consulta dermatológica. Se realizó este estudio con el objeto de conocer el comportamiento de la DMN en nuestra población. Material y métodos. Se estudiaron retrospectivamente 33 casos, de enero de 1996 a enero de 1997, en el Hospital Infantil de México Federico Gómez. Resultados. La DMN representa el 2.78 por ciento de la consulta de dermatología de primera vez. Predomina en hombres con 63 por ciento de los casos. La edad media fue de 4 años y 10.8 meses con una desviación estándar (DE) de 7.4 meses. La forma diseminada fue la más común, afectando con mayor frecuencia extremidades inferiores. El tiempo de evolución el diagnóstico fue de 8.8 meses con DE de 2.3 meses. Se evidenció foco infeccioso en 79 por ciento de los casos, siendo rinosinusitis y parasitosis los más comunes. La biometría hemática reportó eosinofilia en más de la mitad de los pacientes. Sólo se encontró asociación a dermatitis atópica y atopia en 5 casos. La primavera fue la estación con mayor prevalencia. El tratamiento fue con antibióticos y antiparasitarios sistémicos en 27 pacientes y antihistamínicos en 9. Sólo un paciente requirió esteroide tópico. Más del 70 por ciento evolucionaron satisfactoriamente. Conclusiones. Los hallazgos de este estudio son similares a los referidos en la literatura mundial respecto a epidemiología, cuadro clínico y asociación con enfermedades infecciosas

Cutaneous lymphohistiocytic infiltrates in patients with hypogammaglobulinemia.

Six patients (5 to 15 years of age) with hypogammaglobulinemia had scattered papular lesions in association with widespread dermatitis. These disfiguring lesions were a portal of entry for secondary infections and led to social withdrawal. Biopsy specimens from the papules demonstrated dense lymphohistiocytic infiltrate limited to the dermis. Infectious causes (bacterial, fungal, and viral) were excluded. The skin lesions failed to respond to conventional treatment, including topical corticosteroids. Replacement therapy with monthly infusions of high doses of immune serum globulin resulted in gradual improvement and ultimate clearing of the lesions. This unusual skin abnormality, which is unresponsive to traditional treatment, may provide the earliest clue to the presence of hypogammaglobulinemia.
