La administración de melatonina adelantó el sueño en pacientes con síndrome de la fase del sueño retrasada y sincronizó el sueño a los ciclos día-noche en individuos ciegos We considered, after checking over the references retrieved, that 2 papers were appropriate to answer the raised clinical question Durante cuanto tiempo se debe tomar melatonina to assess the efficacy and safety of exogenous melatonin in advancing sleep-wake rhythm in patients with delayed sleep phase disorder.
Sources of data and bibliographic databases: PubMED, Embase and the abstracts of sleep and chronobiologic societies — September, Language restriction: English only. Reference list of the papers found were checked. The authors did not look for additional unpublished papers. Study selection: published articles that were randomized, placebo-controlled, double-blind, clinical trials. They excluded studies in populations with other medical problems but they did not exclude studies with patients diagnosed of ADHD.
They also excluded studies using other clinical outcomes, and studies with biochemical measurements alone. Other interventions, like sleep hygiene, were possible, but other medications for the treatment of insomnia were not allowed. Nine studies were included out of an initial amount of Extraction and processing of data: were done by some authors and checked later by other different authors.
La melatonina: Ventajas y desventajas de la hormona que regula nuestro sueño
The authors extracted from every paper, in addition to the type o study and number of patients in the placebo and treatment groups, data corresponding to variations after the intervention set as endpoints for the following sleep parameters: DLMOclock hour of sleep onset SOWUT, SOL, and TST.
Other data selected: adverse effects, melatonin doses, duration of melatonin treatment, and time of medication administration. A random-effects method was used for the pooling of results.
In all cases results were considered as changes from baseline, either these results came from the parallel studies or from the crossover ones. Assessment of the internal validity: all nine studies selected scored over the cutoff point of 3 in the Jadad scale.
The mean quality score for the 9 RCTs included in the meta-analysis was 4. The 4 studies with children involved patients aged 6 to 14 years. Sample sizes ranged between 19 and Four studies in adults and one pediatric study were crossover studies. The other four studies were parallel-group RCTs. The 3 remaining studies in children were parallel-group RCTs, and the duration of the treatments in durante cuanto tiempo se debe tomar melatonina three was of 4 weeks.
The range of timing for the administration of the intervention was very broad, and different dosages of melatonin were used. Table 1. The analysis of the studies in children showed that melatonin treatment advanced mean clock hour of sleep onset by Melatonin decreased sleep-onset latency by Other adverse events were decrease in appetite and dizziness Conclusion of the authors of the MA: melatonin is effective in advancing sleep-wake rhythm and endogenous melatonin rhythm in delayed sleep phase disorder.
The authors plead no financial conflicts of interest. Location of the study: The Netherlands. Third level center specialized in sleep—wake disorders and disorders of the chronobiology of the sleep.
Referral center placed in a hospital. The patients included were referred patients from local practices of pediatricians and psychiatrists. There was no detailed explanation on the selection procedure. Intervention: placebo versus melatonin.
Length of the treatment period: one week RCT of parallel design. Measurements of the outcome variables: the outcome assessed was the improvement in the SOI measured with the advances in SO, and the shortening of the SOL.
SOL difference melatonin vs. Despite the lack of information the use of melatonin is continuously increasing, even in children.

In the RCT from Van Geijlswijk, however, the term used in the title properly reflected the inclusion criteria of the study. For the MA only were analyzed those studies in which it was specifically reported the timing of melatonin administration in relationship to the circadian clock. Some studies excluded could still be valid and might have offered useful information. The MA did not include the durante cuanto tiempo se debe tomar melatonina strategy and the descriptors used.
There were important limitations of the MA: the language restriction to English and no attempt to localize unpublished researches. The number of participants children involved in the MA was a rather low one patients. Likewise, the number of patients in the RTC of the second paper was also low. Three out of the 4 pRTCs were performed by the same research group and the first author of 2 of them was, actually, one of the authors of the meta-analysis. This might indicate a sampling bias.
Although the choice of studies on sleep parameters could be an adequate choice for the initial investigation on the effect of melatonin versus placebo, they still could be considered as subrogate outcomes.

In the 2 RCTs from Smits, that included significantly higher numbers of participants diagnosed with ADHD most of them medicated durante cuanto tiempo se debe tomar melatonina stimulant drugsit might have been advisable to do a subgroup analysis.
Especially in the RCT of Smits 4 the lack of homogeneity of the groups raises doubt for the generalization of their results. The difference in the percentages of participants with methylphenidate, more than twice higher in the placebo group PG than in the melatonin group MGcould have altered the results, overestimating the effect of melatonin. Something that was truly remarkable is that, in the studies in children with ADHD, the rates of some comorbidities was very high, and because of this, the samples were no representative of the children with ADHD.
In the MA, the dose were collected and reported, but, for the analysis of effects, dosages were not accounted for, by mean of a separated durante cuanto tiempo se debe tomar melatonina.

Assessments of the homogeneity, or a sensibility analysis between studies in the MA, were not reported. Clinical Importance: children given melatonin, in comparison with those that received placebo, advanced the mean clock hour of sleep onset by However, this relatively small change in clock-hour sleep onset achieved raises questions about its clinical durante cuanto tiempo se debe tomar melatonina. The DLMO is considered as a laboratory parameter, and the WUT and TST parameters are measures depending more than on durante cuanto tiempo se debe tomar melatonina medication, on other external factors, like rigid schedules setting the time to get up.
The results also demonstrated that the beneficial effect of melatonin, in terms of sleep improvements, disappear after finishing short-term periods of treatments weeks. In fact, some RTCs even showed a bigger effect for sleep hygiene than for the melatonin intervention. But, on the other hand, the size of the effect showed even if no more than, for instance, 30 minutes could still matter a lot for the specific situation of some children. Clinical Applicability: many of the unanswered questions about exogenous melatonin as a medication are related to long-term treatments AE, duration of the effect, etc.
Further RCTs need to investigate the performance of melatonin in children with real large delays by placing the cutoff point of the inclusion criteria somewhere higher, or by doing a subgroup analysis.
The diagnosis of DSPD remains a point of discussion. In the puberty there is a physiological phase delay, and lifestyle-related phase delays are also common during adolescence. The relative lack of data reported and the discrepancy in the numbers of adolescents and SOI probably reflects the confusion and overlapping of different problems and concepts simple chronic SOI, physiological phase delay of adolescents, true chronobiologic DSPD, imposed sleep deprivation….
