Treating asthma in patients with enuresis: repercussions on urinary symptoms

ABSTRACT Background: Children presenting enuresis are more likely to be asthmatics. The association between enuresis and sleep-disordered breathing has already been demonstrated and several studies have shown at least partial improvement of two thirds or more of the cases of enuresis adenoidectomy. Studies have already described associations between enuresis and allergies but do not assess the repercussions of allergy treatment in enuretics. Objective: This study aims to evaluated whether asthma treatment alters the course of enuresis and whether there is any predictive factor associated with this improvement. Materials and Methods: Twenty patients (5 - 12 years old) with uncontrolled enuresis and asthma, received treatment for asthma. Children were also assessed for the presence of rhinitis and other allergies. The control of asthma was confirmed by a validated questionnaire and primary enuresis by clinical history and wet night diaries. Patients received only asthma treatment. Results: At least partial improvement of enuresis was observed in 55% of the patients with an increase in 64.4% in the number of dry nights at the end of the study (p=0.01). The "presence of other allergies" and "obstruction seen in nasal endoscopy" positively influenced the improvement of urinary symptoms (OR = 3.350; CI 0.844-13.306) and (OR=1.272; CI 0.480-3.370), respectively. Discussion: Until now, only patients presenting upper airway obstruction were known to benefit from the improvement of urinary symptoms when undergoing treatment for their respiratory problems. In our study, we found at least partial improvement in enuresis in 55% of our patients, with only clinical asthma treatment. Conclusion: Controlling asthma in children with primary enuresis resulted in a significant increase in dry nights.

Association between Asthma and Primary Nocturnal Enuresis in Children.

PURPOSE: Enuresis, sleep respiratory disorders and asthma compromise the quality of sleep in children and may occur in association with each other. An association between sleep respiratory disorders and enuresis has already been demonstrated. According to united airways disease abnormalities of the upper and lower airways may coexist. A child who wheezes has a greater chance of snoring and having obstructive sleep apnea. Since asthma and sleep respiratory disorders may be associated, and sleep respiratory disorders are associated with enuresis, we determined the possibility of an association between asthma and enuresis. MATERIALS AND METHODS: Between August 20 and March 2015 parents/guardians of children 6 to 14 years old from 16 elementary schools in our area were randomly chosen for study. Children with nonmonosymptomatic enuresis and urological or neurological disease were excluded. The Tucson and ISAAC (International Study of Asthma and Allergies in Childhood) questionnaires were used to assess sleep respiratory disorders and asthma, respectively. RESULTS: A total of 523 children (283 males and 240 females) with a mean ± SD age of 9.42 ± 2.46 years were included in analysis. The overall prevalence of enuresis was 15.87% (95% CI 12.98-19.26). Asthmatic children with wheezing in the last 12 months were 2.33 times more likely to have had enuresis at some point in life (OR 2.33, 95% CI 1.37-3.95, p = 0.0017). If enuresis was present, the chance increased to 2.78 (95% CI 1.38-5.61, p = 0.0041). Enuretic children were 5.34 times more prone to have apnea reported by parents (95% CI 2.19-13.03, p = 0.0002). CONCLUSIONS: These findings demonstrate that asthma as well as sleep respiratory disorders is associated with primary nocturnal enuresis.

Association between exclusive maternal breastfeeding during the first 4 months of life and primary enuresis.

INTRODUCTION: Although the relationship between enuresis and breastfeeding is still poorly documented in the literature, a possible association is speculated as both are strongly associated with children's development. Therefore, the main objective of this study was to evaluate whether there is an association between primary enuresis and the duration of exclusive breastfeeding. MATERIAL AND METHODS: This is an observational, case-control study, involving 200 children and adolescents from 6 to 14 years old, who were divided into two groups: the enuresis group (EG), composed of 100 children with primary enuresis; and the control group (CG) of 100 matched children without enuresis. The matching criteria were sex, age, and socioeconomic level. Adults responsible for each infant answered a structured questionnaire to identify biological and behavioral factor, as well as the duration of maternal breastfeeding. Children whose parents could not comprehend the questionnaire or children with neurological or psychiatric disorders or secondary enuresis were not included in the study. RESULTS AND DISCUSSION: Evaluating the duration of exclusive breastfeeding, 72% of the subjects of the EG and 42% of the CG had been breastfed for less than 4 months (p < 0.001) (Figure). In bivariate analysis, there was a strong association between symptoms of enuresis with a positive family history of enuresis and duration of exclusive breastfeeding (p < 0.001), and also association with full breastfeeding duration (p = 0.044), number of children (p = 0.045), and parents' education (p = 0.045). After logistic regression, primary enuresis continued to be associated with duration of exclusive breastfeeding and family history of enuresis. The proportion of children that had been exclusively breastfed for more than 4 months was significantly higher in the CG 58% (58/100) than in the EG 28% (28/100) (p < 0.001, OR 4.35, 95% CI 1.99-9.50). CONCLUSIONS: This study confirmed the association between primary enuresis and various factors that have already been studied, with the addition of a new factor, duration of exclusive breastfeeding for less than 4 months, which is strongly associated with primary enuresis.
