Health-related quality of life of food-allergic children compared with healthy controls and other diseases

BACKGROUND

Food allergy is a potentially life-threatening disease, affecting up to 10% of the pediatric population.

OBJECTIVE

The aim of our study was to assess the health-related quality of life (HRQL) of food-allergic patients compared with the general population and patients with other chronic diseases with dietary or allergic burden, in a cross-sectional study.

METHODS

We recruited patients aged 8-17 years diagnosed with food allergy and matched healthy controls recruited in schools. We also included patients with asthma, inflammatory bowel disease, celiac disease, diabetes, obesity, and eating disorders. We used the CHQ-CF87 questionnaire for generic HRQL assessment. Food allergy HRQL was also assessed using specific questionnaires: Food Allergy Quality of Life Questionnaire (FAQLQ) and Food Allergy Independent Measure (FAIM).

RESULTS

One hundred and thirty-five food-allergic children, 255 children with chronic diseases, and 463 healthy controls were included in the analyses. Food-allergic patients had a better HRQL than healthy controls in the Behavior (BE), Bodily Pain (BP), Family Activities (FA), and Mental Health (MH) domains and a worse HRQL in the General Health Perception (GH) domain (p = .048). Food-allergic patients exhibited a better HRQL than patients affected by other chronic diseases, notably diabetes. Although an epinephrine autoinjector had been prescribed to 87.4% of the food-allergic children, only 54.2% of them carried it at all times.

CONCLUSION

Food-allergic patients display overall good HRQL compared with the general population and those with other diseases with daily symptoms and treatments, in line with recent improvements in food allergy management.

Large-scale screening of lipase acid deficiency in at risk population

BACKGROUND

Lysosomal acid lipase deficiency (LALD, OMIM#278000) is a rare lysosomal disorder with an autosomal recessive inheritance. The main clinical manifestations are related to a progressive accumulation of cholesteryl esters, triglycerides or both within the lysosome in different organs such as the liver, spleen, and cardiovascular system. A wide range of clinical severity is associated with LALD including a severe very rare antenatal/neonatal/infantile phenotype named Wolman disease and a late-onset form named cholesteryl ester storage disease (CESD).

METHODS

This study aimed to investigate a cohort of at-risk patients (4174) presenting with clinical or biological signs consistent with LALD using the assessment of LAL activity on dried blood spots.

RESULTS

LAL activity was lower than 0.05 nmol/punch/L (cut-off: 0.12) in 19 patients including 13 CESD and 6 Wolman. Molecular study has been conducted in 17 patients and succeeded in identifying 34 mutated alleles. Fourteen unique variants have been characterized, 7 of which are novel.

CONCLUSION

This study allowed to identify a series of patients and expanded the molecular spectrum knowledge of LALD. Besides, a new screening criteria grid based on the clinical/biological data from our study and the literature has been proposed in order to enhance the diagnosis rate in at risk populations.

Esophageal perforation in eosinophilic esophagitis: five cases in children

Background and study aims  Eosinophilic esophagitis (EoE) is a chronic immune disease with increasing incidence. It is clinically defined by symptoms of esophageal dysfunction and histologically by eosinophilic polynuclear cell infiltration of the esophageal mucosa. Symptoms are not specific and include gastroesophageal reflux disease (GERD), dysphagia, vomiting or dietary blockages. Chronic inflammation of the mucosa may lead to narrowing of the esophageal lumen responsible for impactions. Extraction procedures can be complicated by dissection and perforation. Rare spontaneous ruptures of the esophagus known as Boerhaave syndrome are also possible. We report five cases of esophageal perforation in children with EoE, three with spontaneous rupture and two after an endoscopic procedure. The evolution was favorable under medical treatment.

Legal aspects of sexually transmitted diseases: abuse, partner notification and prosecution

Sexually transmitted diseases (STDs), with special emphasis to HIV infection, involve legal and ethical issues regarding informed consent to submit to a diagnostic, observance of professional secrecy in regard to partner(s) and community; legal troubles of particular difficulties are related to STD involving minors; lastly, physicians must be able to recognize the state of so called medical necessity. Knowledge and awareness of these related obligations are crucial to STD in medical practice; it is also important to allow for proper protection of victims of suspected sexual abuse under observation of healthcare. With regard to this aspect should be emphasized that violence against women and minors is a worldwide problem that has not yet been sufficiently acknowledged. Italian legislation (Law n. 96/1996) against rapes finally gave significant relevance to sex crimes. When sexual abusers have to be evaluated some obstacles may arise for lack of appropriate interdisciplinary approach, with insurance of the collection of biological samples, also related to STD diagnosis and alerts of legal authorities. Personal preconceptions may interfere with investigation if the biological evidences in children are few. In this regard, rules of document "Carta di Noto" drafted in 1996 and reviewed in July 2002 include some specific indications aiming to grant the reliability of the results of technical investigations and authenticity of the statements of the alleged victims.

[Eosinophilic esophagitis. Clinical presentation, allergology and treatment: a series of 22 children]

BACKGROUND AND AIMS

Eosinophilic esophagitis (EE) is a disorder characterized by severe eosinophilic infiltration of the esophagus, with dysphagia and gastroesophageal reflux disease (GERD) symptoms unresponsive to acid blockade therapy but responsive to the removal of dietary antigens. We report information relating to children diagnosed with EE in Nice, France, over a 6-year period.

PATIENTS AND METHODS

We conducted a retrospective study between January 1, 2004, and July 31, 2009, evaluating all children diagnosed with EE. Clinical and demographic data, endoscopic and histological findings, allergology data, and results of treatment were collected and evaluated.

RESULTS

A total of 22 patients, 19 males, median age 9.5 years (range: 0.8-19 years) were reviewed: 7 presented isolated dysphagia, 6 presented GERD symptoms, and 9 both dysphagia and GERD symptoms. Endoscopically, 14 had multiple esophageal white plaques, 7 had linear furrowing, 5 had circular "tracheal" rings, and 5 esophageal narrowing. The median number of esophageal eosinophils/high power field (×400) was 30 (range: 15-80). Eosinophils were localized in the distal, middle, and upper esophagus. Immunoallergy analysis findings were: high peripheral eosinophil count (74%), high total IgE level (65%), high eosinophil cationic protein (ECP) level (90%) with a median value of 69.5 μg/l and high urinary leukotriene E4 (88%). Food antigen sensitization was positive in skin-prick testing in 11 of 18 and in atopy-patch testing in 9 of 17. Dietary restriction improved clinical symptoms in 5 of 10 and local corticotherapy with viscous budesonide improved clinical symptoms in 9 out of 10.

CONCLUSION

EE diagnosis must be considered in children with dysphagia or GERD who do not respond to acid blockade therapy. ECP may be used to guide diagnosis. Local corticotherapy is effective.

Evolution of a patient with Bohring-Opitz syndrome

We detailed the story from birth to the age of 5 years 9 months, of the oldest patient reported with a Bohring-Opitz syndrome with the three main diagnostic criteria: characteristic facial appearance, fixed contractures of the upper limbs and severe feeding difficulties. The facial anomalies described in our patient were microcephaly, bitemporal narrowing, "puffy" cheeks, forehead naevus flammeus, hypoplastic orbital ridges, prominent eyes, broad nasal bridge, high arched palate, buccal-alveola frenula and retrognathism. The magnetic resonance imaging (MRI) of the brain showed a hypoplastic corpus callosum and a narrowed upper cervical canal; and the cervical MRI showed a malformation of the atlas consisting in an agenesis of the anterior arch and an anterior slip of the posterior arch. We focused on her neurological and nutritional evolution. Despite the gastrostomy and a Nissen fundoplication at age 7 months, she still had developmental growth delays overall (<3rd centile). At 3 years 9 months of age, she began to put on weight quickly, which seemed to be atypical. Meanwhile she developed epilepsy, which was controlled with specific drugs. Currently, she is 5 years 9 months old and has significant psychomotor retardation, although this disease is often fatal in early childhood, due to obstructive apnea and unexplained bradycardia.

[Informed consent for HIV diagnostic tests: what to do in case of minors]

AIDS is a clinical picture related to Human Immunodeficiency Virus (HIV) infection. In the last 20 years this infection has spread progressively, with approximately 2.4 million children under 15 years old now infected. The HIV antibody test is generally used to reveal the infection. In most European countries the test is voluntary; in Italy, implementation of the test is now regulated by Law 135/90. Art. 5 of the law states that the test is voluntary while informed consent is obligatory. However, nothing is stated concerning the child's consent. By contrast, other Italian laws (e.g., Law 194/78, Law 194/96 and DPR 309/90) establish that the physician should only accept the wishes of minors after first appraising the maturity of the child and his/her age. Physicians must inform the minor about testing risks, about the meaning of its result, and about the most important aspects of sexual education.. They may then decide to inform the parents if they feel that the child would be unable to take future decisions in the event of a positive HIV antibody test.

Fluconazole therapy for Candida albicans urinary tract infections in infants

Candiduria is rare in newborns and infants, occurring most often in patients with risk factors. When associated with a candidal bezoar in the urinary tract, candiduria is usually treated by systemic amphotericin B and flucytosine plus local irrigation with amphotericin B. We describe the successful treatment of five newborns with a urinary tract infection, on major urological malformations, due to Candida albicans (including three with a candidal bezoar) by fluconazole alone. No adverse effects or recurrences were observed. Fluconazole therapy permits early discharge from the hospital and seems suitable for infants and newborns with a C. albicans urinary tract infection.

[Primary Gougerot-Sjögren syndrome in a 13-year-old girl]

Sjögren's syndrome is uncommon in children, and occurs most often in association with autoimmune diseases (secondary Sjögren's syndrome). We describe the clinical and biological features of a 13-year-old girl with primary Sjögren's syndrome, revealed by recurrent parotitis.

CASE REPORT

This adolescent girl was referred for investigation of multiple episodes of bilateral parotid swelling since age nine, without systemic symptoms. Examination was unremarkable except for enlarged and painless parotid glands. Laboratory investigations, measurement of saliva production, parotid sialography, labial salivary gland biopsy, revealed Sjögren's syndrome without associated disease. Hydroxychloroquine was prescribed with clinical improvement.

CONCLUSION

Recurrent parotitis in children is an uncommon condition. The onset of parotid swelling at five years or over deserves screening for dysimmune disorders, sarcoidosis or Sjögren's syndrome. Diagnosis of Sjögren's syndrome is based on laboratory evidence of autoimmune disorders and minor salivary gland biopsy.

Churg-Strauss syndrome revealed by acute abdominal pain

We describe a 10-year-old girl with Churg-Strauss syndrome, who presented with acute abdominal pain, bloody diarrhea, and pulmonary infiltrates. She had a 6-year history of severe asthma. Bronchoalveolar lavage showed marked eosinophilia. She responded well to high-dose intravenous corticosteroid pulse therapy for 3 consecutive days, followed by oral steroids without developing major side effects. This case should remind pediatricians of the rare existence of this vasculitis in children. Relapse is not uncommon, and long-term careful supervision is necessary.

Renovascular hypertension and vascular anomalies in Alagille syndrome

Alagille syndrome (AS) is characterized by the association of at least three of the following five abnormalities: chronic cholestasis, peripheral pulmonary artery stenosis, vertebral arch defects, embryotoxon, and typical facies. In addition to urological abnormalities, tubulointerstitial nephritis, renal tubular acidosis, and mesangiolipidosis have been noted in AS. The usual manifestations of such renal pathologies rarely include hypertension. We report five patients with at least four of the five major features of AS who developed secondary hypertension of renovascular origin 3.5-28 years after the initial diagnosis of AS. Angiography demonstrated uni- or bilateral renal artery stenosis and various other abnormalities of the main arteries in all five patients: aorta (3 cases), celiac artery (4 cases), superior mesenteric artery (1 case), subclavian artery (1 case). Our findings underscore the value of arterial blood pressure monitoring in patients with AS. If hypertension occurs, a renovascular origin should be sought. The diffuse vascular abnormalities which appeared to be a feature of AS in these patients should prompt larger studies of vascular abnormalities in AS.
