Evaluation of sleep, puberty and mental health in children with long-term melatonin treatment for chronic idiopathic childhood sleep onset insomnia

OBJECTIVES: To establish whether long-term use of melatonin influences pubertal development, sleep quality and mental health development in children as compared with the normal Dutch population of the same age. METHODS: This follow-up research study was conducted in children included in a previous melatonin dose-finding trial. Outcomes were measured using questionnaires (Strength and Difficulties Questionnaire (SDQ), Children's Sleep Habits Questionnaire (CSHQ) and Tanner Stages) adopted for Dutch children. Mean duration of therapy, persistence of effect, adverse events and (other) reasons leading to cessation of therapy were additional objectives of this study. RESULTS: Mean years of usage (n = 51) was 3.1 years (min 1.0 year, max 4.6 years), mean dose 2.69 mg (min 0.3 mg, max 10 mg). Mean SDQ score, mean CSHQ score and Tanner Stages standard deviation scores did not differ in a statistically significant way from published scores of the general Dutch population of the same age and sex. CONCLUSIONS: This follow-up study demonstrates that melatonin treatment in children can be sustained over a long period of time without substantial deviation of the development of children with respect to sleep quality, puberty development and mental health scores, as compared with the general Dutch population

Dose finding of melatonin for chronic idiopathic childhood sleep onset insomnia: an RCT

Contains fulltext : 86695.pdf (publisher's version ) (Open Access)Rationale Pharmacokinetics of melatonin in children might differ from that in adults. Objectives This study aims to establish a dose–response relationship for melatonin in advancing dim light melatonin onset (DLMO), sleep onset (SO), and reducing sleep onset latency (SOL) in children between 6 and 12 years with chronic sleep onset insomnia (CSOI). Methods The method used for this study is the randomized, placebo-controlled double-blind trial. Children with CSOI (n=72) received either melatonin 0.05, 0.1, and 0.15 mg/kg or placebo during 1 week. Sleep was assessed with log and actigraphy during this week and the week before. Outcomes were the shifts in DLMO, SO, and SOL. Results Treatment with melatonin significantly advanced SO and DLMO by approximately 1 h and decreased SOL by 35 min. Within the three melatonin groups, effect size was not different, but the circadian time of administration (TOA) correlated significantly with treatment effect on DLMO (rs=-0.33, p=0.022) and SO (rs=-0.38, p=0.004), whereas clock TOA was correlated with SO shift (r=-0.35, p=0.006) and not with DLMO shift. Conclusions No dose–response relationship of melatonin with SO, SOL, and DLMO is found within a dosage range of 0.05–0.15 mg/kg. The effect of exogenous melatonin on SO, SOL, and DLMO increases with an earlier circadian TOA. The soporific effects of melatonin enhance the SO shift. This study demonstrates that melatonin for treatment of CSOI in children is effective in a dosage of 0.05 mg/kg given at least 1 to 2 h before DLMO and before desired bedtime.13 p

Off-label use of medicinal products

Medicijnen kunnen worden voorgeschreven voor andere ziekten of groepen patiënten dan waar ze voor zijn goedgekeurd. Dat noemen we 'off-labelgebruik' en is onder voorwaarden wettelijk toegestaan. Dit wordt meestal gedaan wanneer er geen andere geschikte behandelmogelijkheden zijn. Zo komt off-labelgebruik bijvoorbeeld vaak voor bij kinderen of bij ernstige ziekten waarvoor nog geen goedgekeurde therapie bestaat. De mate waarin dit voorkomt verschilt per aandoening maar kan omvangrijk zijn. Off-labelgebruik van medicijnen voorziet dus in een medische behoefte, maar kan nog op meerdere punten worden verbeterd. Dit blijkt uit onderzoek van het RIVM. In de praktijk blijkt bijvoorbeeld dat artsen hun patiënten niet altijd informeren en om toestemming vragen wanneer zij geneesmiddelen off-label voorschrijven, ook al zijn ze daar wettelijk toe verplicht. Verder is het belangrijk de kennis over off-labeltoepassingen toegankelijker te maken voor artsen en apothekers; deze kennis is nu versnipperd en niet altijd volledig beschikbaar. Om kennis te vergroten is het ook van belang beter bij te houden wat de werking en eventuele bijwerkingen van off-labelgebruik zijn. Het heeft uiteraard de voorkeur om off-labelgebruik van een medicijn on-label te maken. Hiervoor moet de geneesmiddelfabrikant het initiatief nemen om het bewijs voor de effectiviteit en veiligheid van het gebruik bij de overheid aan te leveren. Als een fabrikant dit initiatief niet neemt, wordt het off-label-gebruik niet genoemd in de bijsluiter. Fabrikanten zouden meer kunnen worden aangespoord om het bewijs te leveren. Ook zou onderzocht kunnen worden of dit initiatief door anderen dan de fabrikant genomen kan worden.Medicinal products may be prescribed for other diseases, or groups of patients, than the ones that they are approved for. This is what we call 'off-label use', a practice which is legally permitted under certain conditions and usually takes place when there are no other suitable treatment options available. Off-label use, for example, frequently occurs in the treatment of children or patients who have serious illnesses for which there is no approved therapy. The extent to which this course of action is taken differs per disease area but can be substantial. The off-label use of medicinal products thus fulfils a medical need, but can still be improved on in several ways. This has been illustrated in research conducted by RIVM. For example, in practice, doctors do not always inform their patients or ask for permission when prescribing medicines off-label, even though they are required to do so by law. Furthermore, it is important to make information about off-label applications more accessible to doctors and pharmacists; currently this knowledge is fragmented and availability is patchy. It is also important to increase levels of awareness about the efficacy of these medicines by keeping track of their performance and recording any possible side effects of off-label use. Of course, it is preferable to make off-label use of a medicinal product 'on label'. To do this, the drug manufacturer must take the initiative to provide proof of the product's efficacy and safety of use to the government. If a manufacturer does not take this initiative, the off-label use is not mentioned in the patient information leaflet. Manufacturers could be encouraged to provide proof. Whether this initiative could be taken by anyone other than the manufacturer might also be investigated.Onderzoeksprogramma Geneesmiddelenkete

Kosteneffectiviteit van implantaten wordt zwaar overschat:Meer onderzoek nodig naar maatschappelijke kosten en bijwerkingen

Nieuwe technologie brengt in de regel hogere kosten met zich mee. In kosteneffectiviteitsstudies worden daarom de kosten en de verwachte opbrengsten in de vorm van gezondheidswinst of kwaliteit van leven tegen elkaar afgezet. Maar welke studies bestaan er voor implantaten en hun (langetermijn)bijwerkingen? En welke rol speelt kosteneffectiviteit bij de afweging om een implantaat wel of niet toe te passen? Het RIVM besloot een verkenning te starten

Variability in market uptake of psychotropic medications in Europe reflects cultural diversity.

In the last 20-30 years, many international studies have found substantial differences in the use of (older) psychotropic medication between European countries. The majority mentioned an important role for attitudes and beliefs towards psychotropic medication. So far, no studies have looked into the effects of cultural diversity on the use of new medications entering the market. As national cultures relate deeply to held values regarding, for example, what is seen as effective versus ineffective or safe versus dangerous, (cultural) diversity in decision making around the role of new medications in clinical practice may already be expected from the first day after market authorization

Reimbursement Restriction and Moderate Decrease in Benzodiazepine Use in General Practice

PURPOSE: To limit misuse and save costs, on January 1, 2009, benzodiazepines were excluded from the Dutch reimbursement list when used as anxiolytic, hypnotic, or sedative. This study aims to assess the impact of this reimbursement restriction on benzodiazepine use in patients with newly diagnosed anxiety or sleeping disorder in general practice. METHODS: Was conducted a retrospective observational database study deriving data on diagnoses and prescriptions from the electronic health records–based Netherlands Information Network of General Practice (LINH). We looked for patients aged 18 years and older with an incident diagnosis of sleeping disturbance (International Classification of Primary Care code: P06) or anxiety (P74, P01) between January 2008 and December 2009. Incidence of these diagnoses, benzodiazepine use, and initiation of selective serotonin reuptake inhibitor (SSRI) treatment was compared between 2008 and 2009. RESULTS: In total, we identified 13,596 patients with an incident diagnosis of anxiety (3,769 in 2008 and 3,710 in 2009) or sleeping disorder (3,254 in 2008 and 2,863 in 2009). The proportion of patients being prescribed a benzodiazepine after a diagnosis was lower in 2009 than in 2008 for both anxiety (30.1% vs 33.7% P <.05) and sleeping disorder (59.1% vs 67.0%, P <.05), as was the proportion of patients with more than 1 benzodiazepine prescription for both anxiety (36.4% vs 42.6%, P <.05) and sleeping disorder (35.0% vs 42.6%, P <.05). We found no increase in the use of alternative treatment for anxiety with SSRIs. CONCLUSIONS: The reimbursement restriction has led to a moderate decrease in the number of incident diagnoses and initiation of benzodiazepine use in patients with newly diagnosed anxiety or sleeping disorder. This finding indicates that in settings where no such reimbursement opportunities exist, physicians have room to reduce benzodiazepine prescribing. (aut. ref.
