Gastrointestinal symptoms in infancy: a population-based prospective study.

BACKGROUND: During the first months of life, infants can suffer from many 'minor' gastroenterological disturbances. However, little is known about the frequency of these problems and the factors which predispose or facilitate their onset. AIMS: (a) To ascertain the frequency of the most common gastrointestinal symptoms in infants during the first 6 months after birth; (b) to evaluate the influence of some variables on the onset of the symptoms. STUDY DESIGN AND PATIENTS: Each of the 150 paediatricians distributed throughout Italy followed 20 consecutive infants from birth to 6 months. 2879 infants (1422 f, 1457 m) concluded the study. The presence of the following symptoms was evaluated: constipation, diarrhoea, vomiting, regurgitation, failure to thrive and prolonged crying fits (colic). Symptoms were recorded whenever the parents requested a clinical check-up or during a set monthly examination. RESULTS: 1582/2879 (54.9%) infants suffered from one of the gastrointestinal symptoms. Regurgitation was the most common disturbance (present in 23.1% of infants), followed by colic (20.5%), constipation (17.6%), failure to thrive (15.2%), vomiting (6%) and diarrhoea (4.1%). Low birth weight was the factor most frequently associated with the onset of gastrointestinal symptoms, followed by low gestational age. Feeding habits did not influence the onset of symptoms, with the exception of constipation, which was linked to a low frequency of breast-feeding. Ninety-three infants (3.2%) were hospitalised for one or more of the gastrointestinal symptoms which were considered. During the whole study period the type of formula-milk was changed in 60% of the infants with one or more gastrointestinal symptoms, and in 15.5% of the infants who did not suffer from any gastrointestinal troubles. CONCLUSIONS: Gastrointestinal symptoms are very common in infants during the first 6 months after birth. These symptoms required hospitalisation only in a small percentage of cases, but led to the prescription of a 'dietary' milk formula in approximately 60% of the cases. Low birth weight and low gestational age were the main factors influencing the onset of the symptoms.

3-min step test and treadmill exercise for evaluating exercise-induced asthma.

A simple exercise test would be useful for detecting exercise-induced asthma, a common problem in asthmatic children. The current study compared the 3-min step test with treadmill exercise for evaluating exercise-induced asthma in asthmatic children and assessed whether responses to both tests are influenced by baseline lung function and habitual physical activity. A series of 154 asthmatic children (84 male children; mean age 12.9 +/- 0.9 yrs) underwent a 3-min step-test and treadmill testing on different days within a week at least 24 h apart. Before both tests each subject did spirometry to obtain the baseline forced expiratory volume in one second (FEV1). After both exercise challenges all subjects did serial spirometry and the lowest FEV1 recorded over time was used to calculate the fall in FEV1 expressed as a percentage of the measured pre-exercise (baseline) value (% fall in FEV1) and the area above the FEV1 curve (AAC0-30 min) expressed as a percentage of the pre-exercise value. Changes in both exercise variables were also analysed in percentile subgroups defined by questionnaire answers on habitual physical activity in hours. The mean % fall in FEV1 was significantly higher for treadmill exercise than for the step test (15.0 +/- 7.5 versus 11.7 +/- 5.9); and the AAC0-30 min was larger for treadmill than for the step test (-261.6 +/- 139.9% versus -197.3 +/- 105.0% min). In all subgroups defined by habitual physical activity the mean % fall in FEV1 decreased more after treadmill exercise than after the step test. After step test and treadmill exercise no significant correlation was found between % fall in FEV1 and baseline lung function, or between % fall in FEV1 among groups defined by habitual physical activity. Although the 3-min step test yields a lower % fall in forced expiratory volume in one second (FEV1) and a lower value of the area above the FEV1 curve than treadmill testing, it is a quick, economical, reproducible and portable alternative procedure for identifying exercise-induced asthma in outpatients and epidemiological studies. Baseline lung function and habitual physical activity have no influence on the amount or duration of exercise-induced asthma.

[Respiratory diseases in infants hospitalized during the 1st 2 years of life for viral lower respiratory tract infections: a one-year follow-up].

BACKGROUND: Epidemiologic data suggest strong links between hospitalisation with bronchiolitis in infancy and subsequent higher risk of developing lower respiratory tract infections (LRTI) and/or hyperreactive airway diseases. The aim of this study was to evaluate in an Italian population the natural history of respiratory diseases in children hospitalised for LRTI when they were <2 years. METHODS: An observational, perspective, longitudinal study was performed through telephone interviews. Nine pediatric tertiary care centres participated to the study evaluating a population of 187 children, hospitalised in the previous year (November 1999-April 2000) for bronchiolitis or pneumonia when they were <2 years of age and participated to a previous study on the prevalence of infant LRTI in Italy (RADAR). RESULTS: Twenty-three (12.3%) children had a gestational age <36 weeks. In the 12 months following the first hospitalisation, an elevated frequency of respiratory symptoms was found. Indeed, 152 (81.3%) children suffered from not-requiring-hospital-admission respiratory infections and 21 (11.2%) were hospitalized again for LRTI: 11.6% had bronchiolitis, 23.5% bronchitis and 35.2% pneumonia. In addition, 1.2% had gs;3 infectious episodes and 21.4% gs;6: 68 (36.4%) showed wheezy bronchitis and 17 (9.1%) were reported to have asthma; 132 children (71%) took antibiotics during the last year, 19.4% >3 times; 111 (59.4%) bronchodilators and 49 (26.2%) oral corticosteroids. One year after the first hospitalisation, 19 subjects (10.2%) were found to be positive to at least one class of allergens by prick test or RAST. CONCLUSIONS: Thus, the demonstration of a high morbidity rate for LRTI, wheezing and asthma in this study group during the first year follow-up after hospital admission further support the need for prophylactic interventions to reduce the morbidity and severity of sequelae of LRTI, in particularly in premature children and/or with additional risk factors.

Bronchoalveolar lavage cell analysis in a child with chronic lipid pneumonia.

In an asymptomatic 4 yr old child with radiographic evidence of parenchymal lung disease, bronchoalveolar lavage (BAL) yielded the diagnosis of chronic lipid pneumonia caused by chronic aspiration of mineral oil given as a laxative. BAL analysis showed a marked reduction in the total number of alveolar macrophages; almost 70% of these cells contained intracytoplasmic lipid vacuoles. It also disclosed lymphocytic (cytotoxic/suppressor) alveolitis. A high percentage of lymphocytes expressed antigen markers of activation (human leucocyte antigen (HLA)-DR), CD54 and CD25). BAL analysis 18 months after mineral oil intake revealed that lymphocytes bearing antigen markers of activation had markedly decreased whereas alveolar macrophages (normal and lipid-laden) had increased. A subsequent whole lung BAL was considered unnecessarily invasive in this otherwise healthy child.

Asthma self-management programmes in a population of Italian children: a multicentric study. Italian Study Group on Asthma Self-Management Programmes.

This study was designed to answer three main questions: 1) Does asthma self-management education reduce asthma morbidity? 2) Are the two programmes "Living With Asthma" and "Open Airways" equally effective in doing so? 3) Is a shortened version of these programmes (4 weeks) as effective as the longer original programme (8 weeks)? Twelve Italian centres of paediatric bronchopneumology selected 312 children with asthma, who were stratified by disease severity, gender and age, and then randomly assigned to an Experimental group which received an educational programme or to a Comparison group, which did not. Of the 312 children selected, 209 (114 Experimental and 95 Comparison) completed the educational protocol and a 1 year follow-up. Data recorded during the last 2 months of follow-up, 10 months after the educational intervention, showed that the Experimental group required significantly fewer emergency treatments: this reduction was more evident in the more severe asthma cases. In the Experimental, but not in the Comparison group, patients with more severe asthma consumed more medications than patients with milder asthma "Open Airways" yielded, in some cases, better results than "Living with Asthma": but a type 2 error is possible. The standard and the shortened programmes proved equally effective. In conclusion, following education, regardless of receiving a short or long educational programme, asthma patients use emergency care services less and use medications more appropriately in comparison with standard care without education. This suggests that short educational programmes can be highly cost-effective in children with asthma.

Relationship between cotinine levels, household and personal smoking habit and season in 9-14 year old children.

The aim of this study was to determine the relationship of salivary cotinine levels with individual and household smoking habits and with the season in a sample (n = 146) of Italian schoolchildren aged 9-14 yrs. Active smoking and environmental tobacco smoke were measured by means of a confidential standardized interview with each participating child and by a self-reported questionnaire administered to the parents. Saliva samples were obtained twice: during winter from all children and during spring from a randomly selected subgroup. "Active smokers" were significantly more likely to be males and to live with smoking family members. Frequency of detectable cotinine both in "nonsmokers" and "active smokers" was significantly correlated with the number of cigarettes smoked by household members. However, for any level of smoking by parents detectable cotinine was more likely to be found in "active smokers" than in "nonsmokers". In "nonsmokers", the proportion of subjects with detectable cotinine decreased significantly in spring compared to winter, a finding not observed in "active smokers". In conclusion, we have demonstrated that passive smoking produces most effect in winter, and is linked to the amount and style of the parents' smoking, mainly related to smoking in presence of children. Conversely, salivary cotinine detected in spring appears to be derived mainly from active smoking.

Early wheezing and breast feeding.

There is uncertainty as to whether breast feeding protects against subsequent illnesses; it has been suggested that breast feeding may have some protective effects on the severity of long-term outcome of bronchiolitis and in reducing morbidity. We have assessed the effects of breast feeding in 266 patients and 199 controls, all patients were early wheezers (i.e., under 2 years old). Between these groups we found differences in socioeconomic, environmental, and atopic conditions, but there were no significant differences in the numbers who had been breastfed. However, within the group who had had early wheezing we found that infants who had been breastfed for at least one month subsequently had less severe wheezing. These results suggest that breast feeding may be a protective factor for early wheezing only during the first month of life, and a delaying factor in the following months.

Enhanced allergic sensitisation related to parental smoking.

The objective of this study was to assess the role of parental smoking in changes, after a four year interval (1983-7), in the prevalence and severity of the atopic state in 166 pre-adolescent children. Allergy skin prick tests were related to parental smoking habits and their changes during this same interval. The total number of cigarettes smoked by parents decreased in 56 families while it increased in only 16. Boys had significantly more persistently positive skin tests and changed more frequently from negative to positive. The skin test index did not show significant changes in girls. This index did not change in children of persistent non-smokers or those starting to smoke during this period, while it increased among sons of those that quit smoking and of persistent smokers. This was not only due to those boys who became skin test positive during follow up. When analysis was restricted to 14 boys who had been skin test positive in 1983 and whose parents were persistent smokers, the index increased in eight, remained unchanged in four, and decreased in only two. This report supports the hypothesis that parental smoking is a factor that, together with specific allergenic exposure, may enhance allergic sensitisation in children.

Increased serum IgE and increased prevalence of eosinophilia in 9-year-old children of smoking parents.

We studied the relationship of serum IgE levels and eosinophil counts with passive smoking in 9-year-old, nonselected children from three Italian towns near Rome. Male children of smoking parents had a significantly higher total count and percentage of eosinophils (p = 0.008) and higher IgE levels (p = 0.01) than male children of nonsmoking parents. Prevalence of eosinophilia (defined as greater than or equal to 4% of total white blood cell count) was significantly correlated with the number of cigarettes smoked by parents among boys (p = 0.003) but not among girls (p = 0.20). There was a significant trend (p = 0.008) for prevalence of eosinophilia to increase with increasing levels of serum IgE. For any given level of serum IgE, the frequency of eosinophilia was higher among children of smoking parents than among children of nonsmoking parents. When parental smoking was studied in a multivariable analysis and after controlling for the other variable, it was still significantly associated with eosinophilia in the children of these smoking parents but not with serum IgE levels. We conclude that parental smoking is associated with a significant enhancement of the expression of the most important markers of allergic sensitization in the children of smoking parents. This is particularly evident for boys and may explain, at least in part, the increased frequency of respiratory symptoms in children of smoking parents.

Controlled studies of childhood asthma self-management in Italy using the "open airways" and "living with asthma" programs: a preliminary report.

The concept of self-management for childhood asthma was introduced to Italy through a scientific exchange agreement with the United States. Two self-management programs, Living with Asthma (LWA) and Open Airways (OA), are being evaluated in three studies, two of which (Pilot and Atri-Viterbo) were conducted by the Respiratory Service of the Pediatric Department of the University "La Sapienza" in Rome and one by 14 Italian university pediatric respiratory centers (Project Italia). In October 1985, 20 children and their 40 parents were enrolled in the Pilot Study. One hundred percent of the mothers and children and 70% of the fathers attended all of the sessions. Theoretical knowledge about asthma and knowledge of asthma self-management behavior were assessed three times by a questionnaire: at the beginning of the program, at the end of the program and one year later. Significant improvements in knowledge of asthma and in knowledge of asthma self-management behavior were demonstrated by both parents and children at the end of the program and one year later. Analysis of clinical symptoms and drug consumption indicated a statistically nonsignificant trend towards a reduction of asthma severity in the year after the program. In the Atri-Viterbo study 8229 children were initially screened by a questionnaire. One hundred eighty-two children with asthma (2.4%) were identified and invited to participate in a self-management program. Open Airways was used in a shortened version. Only 29 families in Atri (22% of the eligible families) and 24 families in Viterbo (50%) ultimately agreed to participate in the program. A comparison of these families with those who did not participate showed that higher social status (p less than 0.001) and more severe asthma (p less than 0.05) were significantly associated with participation. Attendance by mothers and children was 78% in Atri and 61% in Viterbo. Only 5% of the fathers regularly attended the program. Parents who received the program registered a statistically significant increase in knowledge of asthma and knowledge of asthma self-management behavior relative to controls (+13% versus -4%; p less than 0.05). Fourteen university-based pediatric respiratory centers participated in Project Italia, in which the LWA and OA programs were compared in both full length and shortened versions (8 versus 4 h). Four hundred children and their families were enrolled in the study.(ABSTRACT TRUNCATED AT 400 WORDS)
