Methods Patients not in remission and not responding to conventional therapy were offered to initiate LDN as a concomitant treatment. Results Low dose Naltrexone induced clinical improvement in Conclusions Naltrexone directly improves epithelial barrier function by improving wound healing and reducing mucosal ER stress levels.
Clinical data collection During the follow-up, demographic data e. The advantages are that such studies are relatively simple to perform, and that ethical challenges linked to randomized controlled trials are avoided.
However, there are important limitations, and before-and-after studies are often considered to be the weakest quasi-experimental design. It could be argued that they were not representative IBD patients, and that their openness to new and alternative treatments may have led to selection bias. Although the baseline data show little difference between groups, it is possible that bias occurred in the grouping of the study subjects.
The baseline data indicate that there may have been differences in disease activity related to LDN exposure. On the other hand, with a before-and-after design, the study participants served as their own controls.
The total observation time was 4 years for all included study subjects, and it is possible that our findings could be explained by the natural course of disease. A non-exposed control group would have shed light on this potential bias. We believe the inclusion of patients based on data 1—2 years before the observation period reduced this potential bias, among other things by excluding newly diagnosed [incident] IBD patients in the observation period.
The differences between the groups in the dispensing patterns shown in the figures indicate that course of disease is an unlikely explanation for our findings. Correct information from the prescribing doctors is important for reliable inclusion of patients and analysis.
The data suggest some imprecision in NorPD. However, the observed prescription patterns indicate that a large majority of the study subjects actually had IBD. Possibly, patients with ICD reimbursement codes experienced a more active phase of disease than did the patients who were handled solely by primary care.
Therefore, a selection bias towards patients with more severe disease is possible, since they received specific ICD codes by a specialist in secondary care. This is reflected in the higher consumption of several drugs being studied. On the other hand, medication given directly to inpatients by hospitals is not recorded, which means that medication administered in the most severe flares may not have been captured.
Bias due to misclassification of exposure is possible, but we believe this would be negligible due to there being very few LDN-using patients in Norway before the TV documentary in February We used NorPD data to identify study participants.
Previous research based on NorPD data has confirmed optimal and unbiased case finding in myasthenia gravis, 16 and the database has been used to calculate reliable incidence rates of diabetes mellitus. Even though the study population was larger than in previous studies on LDN use in CD and UC, the results indicate that the number of included study subjects was insufficient to detect differences that could be clinically relevant.
Similar, but not statistically significant, patterns in the changes in medication were seen in CD and UC as were seen in many of the findings in the total IBD analysis.
We could have used less strict inclusion criteria, but this would have reduced the external validity. We have not identified other pharmacoepidemiological studies on LDN apart from our own research. In an open-label study without a control group, in which 17 patients received 4.
Adverse effects were minimal in both of these studies. In a pilot study designed to evaluate safety and tolerability of LDN in 14 pediatric CD patients, significant clinical improvements were observed. A controlled study using a rat model of indomethacin-induced CD showed significant improvements following LDN treatment. There are several proposed mechanisms of action for the alleged effects in IBD. The gastrointestinal tract has a large number of opioid receptors, and antagonism of these could have therapeutic effects in the inflamed mucosa, both through direct effects on bowel motility and through the postulated opioid receptor—modulated immunologic effects.
Interference with the regulation of endogenous opioids has also been suggested. The most important, though controversial, possible explanation of our findings, is that the patients who started LDN therapy experienced clinical improvement, and that the need for medication was decreased.
It is important to emphasize that, at best, the observed changes in drug use may serve only as a proxy for efficacy. Our data do not provide any direct clinical information. It is plausible that clinical improvements are linked to reductions in drug dispensing in IBD, but there is insufficient evidence to conclude that this is a prudent efficacy measure in CD or UC.
Nevertheless, the observed reductions in drug use following LDN use should be interesting for patients, clinicians and for those who pay for health care. They could be an indication that LDN may play a role in reducing polypharmacy in this patient group, thereby reducing costs and risks of adverse effects.
If actually proven efficacious in future studies, LDN could partially replace more expensive standard treatments. GR contributed to the conception of the study, designed the study, performed statistical analyses and drafted the manuscript.

The other study assessed eight weeks of LDN 0. The primary purpose of the pediatric study was to assess safety and tolerability. Both studies were rated as having a low risk of bias. In the adult study point clinical response rates were significantly higher in those treated with LDN than placebo.
The effect of LDN on the proportion of adult patients who achieved a point clinical response was uncertain. However, there was no statistically significant difference in the proportion of patients who achieved endoscopic remission.
Pooled data from both studies show no statistically significant differences in withdrawals due to adverse events or specific adverse events including sleep disturbance, unusual dreams, headache, decreased appetite, nausea and fatigue.
No serious adverse events were reported in either study. GRADE analyses rated the overall quality of the evidence for the primary and secondary outcomes i. What is Crohn's disease? What is naltrexone? Active disease is considered or greater. A response to therapy is considered a decline in the CDAI score of points from baseline.
Gut ; This score ranges from based upon the extent and severity of inflammation and ulcers seen during endoscopy of the colon. Histology Inflammatory Score by Colon Biopsies [ Time Frame: 12 weeks ] Histology scores to assess microscopic inflammation and structural architecture were determined at baseline and after 12 weeks of either naltrexone therapy or placebo by mucosal biopsy samples obtained during colonoscopies.
The pathology specimens were reviewed and scored by a Pathologist blinded to the treatment. The mean scores at baseline were the same between both groups. Differences between naltrexone and placebo treated subjects was assessed. The range in scores could be , with 0 representing no inflammation and 25 being maximum or severe inflammation..
