RESUMEN
BACKGROUND: Eating disorders in children and adolescents can have serious medical and psychological consequences. The objective of this retrospective quantitative study is to gain insight in self-reported Health Related Quality of Life (HRQoL) of children and adolescents with a DSM-5 diagnosis of an eating disorder. METHOD: Collect and analyse data of patients aged 8-18 years, receiving treatment for an eating disorder. At the start and end of treatment patients completed the KIDSCREEN-52, a questionnaire measuring HRQoL. RESULTS: Data of 140 patients were analysed. Children diagnosed with Anorexia Nervosa, Bulimia Nervosa, and Other Specified Feeding or Eating Disorder all had lower HRQoL on multiple dimensions at the start of treatment, there is no statistically significant difference between these groups. In contrast, patients with Avoidant Restrictive Food Intake Disorder only had lower HRQoL for the dimension Physical Well-Being. HRQoL showed a significant improvement in many dimensions between start and end of treatment, but did not normalize compared to normative reference values of Dutch children. CONCLUSION: The current study showed that self-reported HRQoL is low in children with eating disorders, both at the beginning but also at the end of treatment. This confirms the importance of continuing to invest in the various HRQoL domains.

The AQUACROSS project was an unprecedented effort to unify policy concepts, knowledge, and management of freshwater, coastal, and marine ecosystems to support the cost-effective achievement of the targets set by the EU Biodiversity Strategy to 2020. AQUACROSS aimed to support EU efforts to enhance the resilience and stop the loss of biodiversity of aquatic ecosystems as well as to ensure the ongoing and future provision of aquatic ecosystem services. The project focused on advancing the knowledge base and application of Ecosystem-Based Management. Through elaboration of eight diverse case studies in freshwater and marine and estuarine aquatic ecosystem across Europe covering a range of environmental management problems including, eutrophication, sustainable fisheries as well as invasive alien species AQUACROSS demonstrated the application of a common framework to establish cost-effective measures and integrated Ecosystem-Based Management practices. AQUACROSS analysed the EU policy framework (i.e. goals, concepts, time frames) for aquatic ecosystems and built on knowledge stemming from different sources (i.e. WISE, BISE, Member State reporting within different policy processes, modelling) to develop innovative management tools, concepts, and business models (i.e. indicators, maps, ecosystem assessments, participatory approaches, mechanisms for promoting the delivery of ecosystem services) for aquatic ecosystems at various scales of space and time and relevant to different ecosystem types.

BACKGROUND: Healthcare is a labor-intensive sector in which half of the expenses are dedicated to human resources. Therefore, policy makers, at national and internal levels, attend to the number of practicing professionals and the skill mix. This paper aims to analyze the European forecasting model for supply and demand of physicians. METHODS: To describe the forecasting tools used for physician planning in Europe, a grey literature search was done in the OECD, WHO, and European Union libraries. Electronic databases such as Pubmed, Medine, Embase and Econlit were also searched. RESULTS: Quantitative methods for forecasting medical supply rely mainly on stock-and-flow simulations and less often on systemic dynamics. Parameters included in forecasting models exhibit wide variability for data availability and quality. The forecasting of physician needs is limited to healthcare consumption and rarely considers overall needs and service targets. Besides quantitative methods, horizon scanning enables an evaluation of the changes in supply and demand in an uncertain future based on qualitative techniques such as semi-structured interviews, Delphi Panels, or focus groups. Finally, supply and demand forecasting models should be regularly updated. Moreover, post-hoc analyze is also needed but too rarely implemented. CONCLUSION: Medical human resource planning in Europe is inconsistent. Political implementation of the results of forecasting projections is essential to insure efficient planning. However, crucial elements such as mobility data between Member States are poorly understood, impairing medical supply regulation policies. These policies are commonly limited to training regulations, while horizontal and vertical substitution is less frequently taken into consideration.

INTRODUCTION: A lot of studies have demonstrated the possibility of reducing the number of post-operative complications in the domain of major surgical procedures with the use of medical preventive techniques. However, complications following surgical procedures are unfortunately frequent and are a major problem, not only because of the impact for the patient, but also because of economic consequences that they provoke. The aim of the present study is to evaluate the extra length of stay and the extra cost, born by the hospital and the social security, linked to complications, incurring after major surgical procedures. MATERIAL AND METHODS: Study based on the data from 13 Belgian hospitals for the year 2012. Complications were extracted through medical discharge summaries. The cost born by the social security was assessed on the basis of the billing data, hospital cost are taken from cost accounting studies. RESULTS: The rate of complication for all the hospitals is 6.6%. About 30.3% of inpatient stays having a major or extreme severity of index had a complication during the stay, 1.8% of stays with a minor or moderate severity of index had a complication. The extra length of stay is 19.38 days when the stay has had a complication (p < 0.001). The additional mean cost borne from the hospital perspective is 21 353.07 and 8 026.65 for the social security. This additional mean cost varies greatly from one hospital to another. DISCUSSION/CONCLUSION: The present study has shown that the actual financing do not cover real hospital costs in the field of major surgical procedures having caused complications. Results should encourage Belgian authorities to propose and finance preventive measures in order to reduce these complications, which represent major economic impacts, not only for authorities but also for hospitals.

INTRODUCTION: The last few years have seen major changes in the Belgian medical planning. The paper aims to describe them and to assess how they will affect the medical demography. METHOD: Grey literature review and federal and federated entities legislation summary. RESULTS: A new dynamic register allows a better knowledge of medical workforce in all sectors of labour market. Recent legislation evolutions induce fragmentation of competences related to human resource for health planning : federal authorities are responsive for the fixation of number of GP and specialists and community authorities for registration of health professionals and fixation of sub-quotas in different branches of specialised medicine. Finally, the French Community has setting up a multiple selection system of medical students that have to past an 'orientation test', a possible reorientation after January examinations and then a numerus fixus at the end of the first academic year. CONCLUSIONS: Dynamic register improves the knowledge of medical workforce repartition. However, the assessment of its volume shows methodological limitations. From an operational viewpoint, the fragmentation of competences will ask coordination effort from all authority levels to avoid impairment in planning process. Finally, French Community has to consider evaluation and ambitious revision of medical workforce planning in their region.
INTRODUCTION: Ces dernières années, la planification de l'offre médicale belge a connu des bouleversements majeurs. Cet article propose de les décrire et d'en apprécier l'impact pour le futur de la démographie médicale. METHODE: Revue de la littérature grise et des textes législatifs nationaux et de la Communauté française. RESULTATS: La mise en place d'un cadastre dynamique a permis de mieux connaître la force de travail des médecins au sein des différents secteurs d'activité sur le marché de travail. Les récentes évolutions législatives montrent un morcellement accru des compétences en termes de planification : le Fédéral étant compétent pour la fixation des quotas de généralistes et de spécialistes, et les Communautés pour l'enregistrement des professionnels de santé et des sousquotas par disciplines. Enfin, la Communauté française a mis en place un système d'hyper-sélection des candidats aux études de médecine soumis successivement au test d'orientation, à la session de janvier suivi d'une éventuelle réorientation, et à la session de juin accompagnée de l'épreuve de classement du numerus fixus. CONCLUSIONS: La mise en place du cadastre dynamique améliore grandement la connaissance de la répartition de la force de travail médicale. Cependant, l'évaluation de son volume pose d'importantes questions méthodologiques. D'un point de vue opérationnel, le morcellement des compétences demandera des efforts de coordination entre les différents niveaux de pouvoir pour ne pas porter préjudice au processus de planification. Enfin, la Communauté française ne pourra faire l'économie d'une évaluation et d'une révision ambitieuse de la planification des médecins sur son territoire.
RESUMEN
BACKGROUND: The ISPAD guideline 2011/2014 advises annual podiatric screening to detect foot complications and identify other possible risk factors such as functional and structural foot abnormalities. The aim of this study was to assess the prevalence and awareness of neurovascular, functional and structural foot abnormalities in children and adolescents with type 1 diabetes mellitus (T1DM). METHODS: All patients aged 0-18 years with T1DM were invited for a foot examination and structured questionnaire by a certified podiatrist. RESULTS: Three of the examined patients (n=128) showed signs of possible long-term complications. Structural and functional foot problems were observed in 71.9% (n=92). Of all patients, 38.3% (n=49) required further treatment by a podiatrist. CONCLUSIONS: Functional and structural foot abnormalities are a frequent problem in children with T1DM in the southern part of the Netherlands. These abnormalities are an additional risk factor for developing long-term foot complications. Education in and implementation of the guideline are necessary.

BACKGROUND: The planning of human medical resources has been in progress since 1996. The aim of this paper is to describe the process which occurred in Belgium and to point out its assets and limits. METHODS: Literature review, analysis of the Belgian legislation at national and community (Flemish and French-speaking) level and analysis of the projection model. RESULTS: In Belgium, planniing is performed at two different levels of power. Firstly, the federal State determines the number of physicians who will access to the professional titles enabling them to obtain reimbursement of care by Health Funds. It is sustained by a supply projection type " stock and flows", an assessment of the number of required physicians (including healthcare expenditures by age and sex) and the purpose of equalizing Dutch-speaking and French-speaking medical densities. Secondly, Communities, are responsible for training and, as such, are organizing the selection at this level : entrance examination in the North and various selection procedures (now repealed) in the South. CONCLUSION: Worldwide, the managers of medical planning are faced with decisions related to appropriate numbers for human resources, given population needs, use of services and professional productivity. They have to address concerns from medical surplus to shortage. The case study of Belgium provides insight of various parameters which should be taken into account for national planning of physicians. It also shows the difficulty to assess a complex future and the factors which often hinder the implementation of evidence-based decisions.

INTRODUCTION: The nonurgent use of the emergency department (ED) for pediatric patients is an increasing problem facing healthcare systems worldwide. To evaluate the magnitude of the phenomenon and to identify associated factors, an observational prospective survey was performed including all patients (<15 years) attending the ED in 12 Belgian hospitals during 2 weeks in autumn 2010. Use of ED was considered appropriate if at least one of the following criteria was met: child referred by doctor or police, brought by ambulance, in need for short stay, technical examination or orthopedic treatment, in-patient admission, or death. Among the 3,117 children, attending ED, 39.9 % (1,244) of visits were considered inappropriate. Five factors were significantly associated with inappropriate use: age of child, distance to ED, having a registered family doctor, out-of-hours visit, and geographic region. The adjusted odds ratio and 95 % confidence intervals are respectively-1.7 (1.3-2.0), 1.7 (1.3-2.2), 1.5 (1.1-2.2), 1.5 (1.2-1.9), and 0.6 (0.5-0.8). CONCLUSIONS: Almost 40 % of all paediatric ED attendances did not require hospital expertise. The risk of an inappropriate use of ED by pediatrician patients is predominantly associated with organizational and cultural factors. Access, equity, quality of care, and medical human resources availability have to be taken into account to design financially sustainable model of care for those patients. Furthermore, future research is needed to explain reasons why parents visit ED rather than using of primary-care services.

The economical science will gradually introduce the health economy of which the definition urges to seek for a better distribution between public and private means to do more and better for the public health. The health market is principally conducted by the supply and demand law. The needs, the supply and demand and the consumer's behaviour are different in this particular market which evolves continuously and progressively goes closer to the market economy. The health status of each human represents the health demand and the medical goods and services are the supply. The role of the valuation studies in health economy is to favour a better use of the limited resources to the unlimited needs. The basic principles of a cost efficacy analysis are relatively simple. They compare the incremental costs with the increase of efficacy. The QALY is built with a combination between life quality and quantity in a unique concept: the measurement of the quality of life of a human at a given moment. The 100th report of the KCE established the restrictions of this method and its absolute use as in England. Indeed we have to take into account other factors as the added value in terms of clinical efficacy, accessibility, the seriousness of pathological cases and the emotional situation. The ICER (Incremental Cost Efficacy Ration) has a lot of weaknesses and may give the illusion that the reimbursement decision is easy. Nevertheless to neglect the economic approach is not ethical. ICER is first of all a balance factor.

The objective of the analysis is to estimate the long-term costs and effects of clopidogrel versus aspirin in the secondary prevention of ischemic events in patients with a history of more than one atherothrombotic event in Belgium. The following high-risk subpopulations within the CAPRIE trial were analysed: patients with a history of myocardial infarction (MI) or ischemic stroke (IS) prior to the event qualifying for enrolment and patients with prior multiple vascular territory involvement. A Markov model that combined clinical, epidemiological and cost data was used. The base case scenario was based on a treatment duration of 5 years reflecting the long-term use of clopidogrel. A lifelong time horizon was taken, by applying life expectancy data based on the Saskatchewan database. Belgian cost estimates were derived from publicly available sources and literature. Long-term clopidogrel treatment compared to aspirin in patients with a history of MI or IS prior to the event qualifying for enrolment is associated with an incremental cost-effectiveness ratio (ICER) ranging between 2.730 Euro per life year gained (LYG) for the first year of treatment and 8.000 Euro/LYG for a treatment duration of 5 years. In patients with prior multiple vascular territory involvement the ICER of clopidogrel compared to aspirin lays between 3.110 Euro and 5.750 Euro/LYG for the respective treatment durations. Use of clopidogrel for the prevention of subsequent cardiovascular events in patients with a history of more than one ischemic event is associated with favourable ICERs, independently of the presumed treatment duration. Sensitivity analyses varying life expectancy, efficacy of clopidogrel, costs of events and cost of adverse events and discount rates demonstrated the robustness of the results.

OBJECTIVE: To test the effectiveness at 6 and 12 months' follow-up of group cognitive behavioural therapy (CBT) compared with blood glucose awareness training (BGAT) in poorly controlled Type 1 diabetic patients and to explore the moderating effect of baseline depression. RESEARCH DESIGN AND METHODS: Adults with Type 1 diabetes (n = 86) with glycated haemoglobin (HbA(1c)) >or= 8% were randomized to CBT or BGAT. Primary outcome was HbA(1c) control. Secondary outcomes were: self-care, diabetes-related distress (Problem Areas in Diabetes scale; PAID), diabetes self-efficacy (Confidence in Diabetes Self-care scale; CIDS) and depressive symptoms (Centre for Epidemiological Studies--Depression scale; CES-D). Measurements were scheduled before CBT and BGAT, and at 3, 6 and 12 months after. Differential effects were analysed for the subgroup of patients reporting low vs. high baseline levels of depression. RESULTS: Neither CBT nor BGAT had a significant impact on HbA(1c) at 6 and 12 months' follow-up. Both interventions resulted in lower depressive symptoms (CES-D 15.7-13.3, P = 0.01) up to 12 months, but only CBT was effective in lowering HbA(1c) in patients with high baseline depression scores (HbA(1c) 9.5-8.8%) up to 1 year of follow-up (P = 0.03). CONCLUSIONS: Our findings suggest that group CBT can effectively help Type 1 diabetic patients with co-morbid depression achieve and maintain better glycaemic outcomes.

OBJECTIVE: To determine if a reduced medical practice reimbursed by the sickness insurance is a proof of medical plethora. Enquiry design : Descriptive observation transverse design. POPULATION: The French-speaking general practitioners and specialists questioned in 2003 about their reduced activity volume recorded in 2000 by the National Institute of the Sickness - Disability insurance (INAMI) on the French Community territory. METHOD: All French-speaking general practitioners and specialists, not reaching the accreditation activity level in 2000, were selected starting from databank of the INAMI. A questionnaire was transmitted to the physicians by mailing via the INAMI services. The answer rate was 44,0 % for the specialists and 40,5 % for the general practitioners. RESULTS: In 2000, 47,7 % of the French-speaking general practitioners and 23,3 % of the French-speaking specialists did not reach the activity level given the right to be accredited by the INAMI. After the enquiry, only 5,5 % of the general practitioners and 5,7 % of the specialists had really a reduced activity. It was explained for a great part by the choice of career guidance out of the INAMI system and under-declaration of foreign working and retirement. CONCLUSIONS: The data bases of the INAMI are the only sources of individual medical activity recording. Their uses, in term of medical manpower planning, must be done with corrective factors issued from this study. The accreditation activity level is a good indicator to underline the activity out of the sickness insurance sector.

AIMS: To assess the effects of cognitive behavioural group training (CBGT) on glycaemic control, diabetes self-efficacy and well-being in Type 1 diabetes patients in persistent poor glycaemic control. METHODS: In a randomized controlled trial, a total of 107 patients with Type 1 diabetes in poor glycaemic control (HbA(1c) > or = 8%) were assigned to a 6-week CBGT or blood glucose awareness training (BGAT) as control condition. The intervention was preceded by a 3-month run-in period. Glycaemic control (HbA(1c)), diabetes-specific self-efficacy (CIDS), diabetes-related distress (PAID) and depressive symptoms (CES-D), were assessed at baseline (T1), directly before (T2) and 3 months after (T3) the intervention. RESULTS: No significant changes in HbA(1c) were found after CBGT, whilst diabetes self-efficacy increased (mean CIDS score 71.6 +/- 14.0 to 74.3 +/- 12.2) and diabetes-related distress (mean PAID score 47.0 +/- 21.6 to 42.6 +/- 20.8) and depressive symptoms decreased (mean CES-D score 16.9 +/- 12.8 to 13.5 +/- 12.6). Changes in psychological outcomes were similar for both treatment groups. Diabetes self-care behaviours improved equally. Drop-out rate, which was higher among CBGT participants, was relatively low overall (total n = 15, 17.05%), and both interventions were well-appreciated by the participants. CONCLUSIONS: CBGT was successful in improving self-efficacy, diabetes-related distress and mood at 3 months' follow-up, but not in improving glycaemic control.

After the definition of the economy and its different types, we have to stress the political economy which integrates pure economy and society. The economical science will gradually introduce the health economy of which the definition urges to seek for a better distribution between public and private means to do more and better for the public health. The market economy is different from the state economy. She is principally conducted by the supply and demand law. The consumer's behaviour in a competitive market has some characteristics which favour the balance of this market. The healthcare market put also a health supply and demand forward but not with the same values. The needs, the supply, the consumption and the consumer's behaviour are different in this particular market which quickly evolves and progressively goes closer to the market economy. Is the healthcare an economical good or duty? The choices' criteria and the priorities are changeable. The role of the valuation studies in health economy is to try to clarify them and to favour a better use of the limited resources to the unlimited needs.

The objective of this study was to compare the inflammatory marker eosinophil cationic protein (ECP) with peak expiratory flow (PEF) in determining the therapeutic needs of inhaled corticosteroids in asthma patients assessed as asthma symptoms. A randomized, single-blind study over 6 months was performed at six specialist centres in Europe. In total, 164 adult patients with moderate to severe symptomatic asthma and regular use of inhaled corticosteroids were included. After a run-in period of 2 weeks patients were randomly allocated to the ECP or the PEF monitoring group. The dose of inhaled cort costeroids was adjusted every fourth week based on the current serum ECP value or pre-bronchodilator morning PEF values as surrogate markers of therapeutic needs. At the end of the study there were no statistically significant differences in the mean daily symptom score or the percentage of symptom-free days between the two groups. The mean daily dose of inhaled corticosteroids was similar in the two groups at the start of the study but the algorithms used to adjust the dose of inhaled corticosteroids resulted in an increased use of inhaled corticosteroids in both groups. The mean daily dose of inhaled corticosteroids over the whole study period was significantly lower in the ECP group compared withthe PEF group (1246 vs. 1667 microg, P = 0.026). In the ECP group, forced expiratory volume in I sec (FEV)% predicted was lower at the end ofthe study compared with the begining (92% vs. 87%, P = 0 .0009), although there was no significant difference between the two groups. None of the used algorithms for ECP and PEF led to improvement in symptom scores, in spite of increased doses of inhaled corticosteroids. In this respect, both methods were equivalent and insufficient. Recommendations suggesting lung function tests in current guidelines may be difficult to translate into clinical practice, however, a combination of inflammatory markers, lung function and symptoms may still improve asthma control.

SUMMARY. Childhood rates for admission and readmission for asthma are highest under the age of 5 years. From a registration study in 0-4-year-olds, 100 patients (68 male) were admitted to hospital for asthma and followed for 1 year, yielding a total of 136 admissions. To examine factors that may play a role in admissions and readmissions, histories and laboratory tests for atopic status at initial presentation, and clinical data on admission were evaluated. Age groups 0-1 year (n = 54) and 2-4 years (n = 46) were analyzed separately, of whom 20 (37%) and 9 (20%) patients, respectively, had at least one readmission. In the age group 2-4 years, patients with antibodies against inhalant allergens, determined by radioallergosorbent test (RAST), had a significantly higher risk of readmission (RR = 1.54; 95% CI, 1.22-1.95). In the age group 0-1, year prevalence of sensitization to inhalant allergens was low (20% vs. 72% in age group 2-4 years) and constituted only a slight risk (P = 0.097) for readmission. A history of eczema showed a negative association in the age group 0-1 year. Treatment of the first admission did not differ between children only admitted once and those requiring readmission. In both age groups, clinical features at admission did not differ significantly between first and subsequent admissions, and neither did length of stay. Number of readmissions were higher in the age group 0-1 year than in the age group 2-4 years (27/81 (33%) vs. 9/55 (16%), P = 0.028), with no indication of a lower threshold for admission. In the age group 0-1 year, 60% of the readmissions occurred within 2 months of first hospitalization. Moreover, in the age group 0-1 year a trend was observed that inhaled steroids were prescribed less frequently on discharge following first admission in those children who were readmitted than in the children who had a first admission only (4/20 (20%) vs. 15/34 (44%), P = 0.073). More "aggressive" therapy with anti-inflammatory drugs and close medical follow-up after discharge seem to be indicated.

Hospital admissions and readmissions for asthma in early childhood remain causes for concern. The purpose of this study was to identify predisposing risk factors related to asthma exacerbations and precursors of hospital admissions in young children. Subjects were patients with doctor-diagnosed asthma from a clinical registration study, aged 0-4 years, and followed up for 2 years. Data from histories and laboratory tests for atopic status at initial presentation, and the patient's condition at visits over the 2-year follow-up period were evaluated. Exacerbation was defined as increases in cough and/or wheeze and/or breathlessness, increase in beta(2)-agonist use, and a clinical need for a short course of oral corticosteroids. Age groups 0-1 year and 2-4 years, based on age at initial presentation, were analyzed separately. In the age group 0-1 year, 71/113 (63%) patients had at least one exacerbation, and 20 experienced recurrent exacerbations (>/=3). Predisposing risk factors for exacerbation were damp housing (odds ratio (OR) 7.6 (2. 0-28.6)) and colds (OR 3.6 (1.4-9.6)), and for recurrent exacerbations sensitization to inhalant allergens (Phadiatop(R)) (OR 8.1 (1.6-40.5)) and damp housing (OR 3.8 (1.1-12.8)). Hospital admissions were significantly associated with number of exacerbations. In the age group 2-4 years, 58/144 (40%) patients had at least one exacerbation, and 21 experienced recurrent exacerbations (>/=2). Predisposing risk factors for exacerbation were mean age at initial presentation (OR 0.92 (0.88-0.97)) and level of total IgE (OR 2.3 (1.4-3.9)), whereas for recurrent exacerbations no predictor variables were found. Hospital admissions were significantly associated with damp housing. Results from this study may facilitate recognition of young asthmatic patients at risk of (recurrent) exacerbations, and help to identify those in whom early intervention with anti-inflammatory therapy may be necessary. We also emphasize the importance of preventive measures in decreasing damp housing.

A registration study from clinical practice was set up to assess the prognostic value of symptoms and laboratory data at first visit for doctor-diagnosed 'asthma' in early childhood. A total of 419 children aged 0-4 y, who were newly referred to the outpatient department of the Juliana Children's Hospital with possible asthma were enrolled over a 2-y period. Data from history taking, physical examination, laboratory tests for atopic status at first visit and data from follow-up visits were recorded. Two years after the first visit all medical records were reviewed for diagnostic label. The age groups 0-1 y and 2-4 y were analysed separately, because respiratory symptoms are often transient and sensitization to inhalant allergens is uncommon before the age of 2 y. The clinical diagnosis 'asthma' was made in 113 of 231 (49%) children aged 0-1 y and in 144 of 188 (77%) children aged 24 y. Characteristics from history taking indicated shortness of breath was the most prognostic symptom in both age groups. Eczema, wheeze and non-allergic provoking factors (weather conditions) were further predisposing factors in the 0-1 y group, as were allergic provoking factors (inhalant allergens) and absence of ear-nose-throat-history in the 2-4 y group. Adding laboratory data to history total serum IgE had prognostic value, but specific serum IgE against inhalant allergens (Phadiatop) was a strong predisposing factor, especially in the 2-4 y group. These prognostic characteristics may enhance early recognition of asthma in infants and improve asthma care in clinical practice.

Long-term treatment with salmeterol produces tolerance for its protective effects against bronchoconstrictor stimuli in patients with asthma. There is human in vitro evidence that theophylline may prevent beta2-adrenoceptor downregulation. Therefore, we investigated the effect of theophylline on the tolerance to the protective effect of salmeterol against histamine challenge in asthma in vivo. In a parallel 6-wk study, 25 asthmatics were treated with theophylline (mean serum level +/- SEM: 9.9 +/- 1.1 mg/L, Days 1 to 40) or placebo, combined with inhaled salmeterol (50 microgram twice daily, Days 8 to 36). Histamine challenges were carried out by tidal breathing method at entry, and at Days 4, 8, 22, 36, and 40. The response was measured by PC20. There was no significant change in PC20 after 4 d monotherapy with theophylline or placebo (mean difference +/- SEM: 0.54 +/- 0.39 and -0.02 +/- 0.41 doubling dose [DD], respectively; p > 0.15). One hour after the first dose, salmeterol afforded significant protection against histamine, as shown by an increase in PC20 in both the theophylline and placebo group (by 3.49 +/- 0.28 and 3.36 +/- 0.32 DD, respectively; p < 0. 001). However, after 2 and 4 wk salmeterol treatment, the improvements in PC20 by salmeterol were significantly reduced to 1. 80 +/- 0.35 and 1.69 +/- 0.36 DD, respectively, in the theophylline group (p < 0.001), and to 1.55 +/- 0.47 and 1.52 +/- 0.56 DD, respectively, in the placebo group (p < 0.002). These changes were not significantly different between the groups (p > 0.80). After cessation of salmeterol treatment, PC20 was not significantly different from the values at entry in either group (p > 0.90). We conclude that regular theophylline treatment neither prevents, nor worsens, the development of tolerance to the bronchoprotective effect of salmeterol in asthmatics in vivo.
