We received an email from a concerned reader
regarding the claims made in the above paper that a patient
experienced resolution of psoriatic patches on her body after
having received a cocktail of nutritional supplements, while
adhering to a regimen that prescribed dietary changes for a period
of 6 months. Although the findings, while preliminary in nature,
were potentially encouraging, the Editor of Experimental and
Therapeutic Medicine agrees with the reader that the study
exhibited a number of limitations. A follow-up study was not
conducted, and the possibility of disease recurrence was not
investigated. A follow-up study of the patient examined would also
have demonstrated the effectiveness of this therapy in a long-term
period. Moreover, a further limitation is that, since the present
study was a case report, the findings reflect the response of an
isolated patient incident. Clinical studies with a larger sample
size would offer clearer insights into the efficacy of this
therapy, allowing the statistical determination of clinical
outcomes and benefits. Finally, the Editor also noted that the
study contained an undeclared potential conflict of interest, since
the nutritional supplements Vitacor Plus, ProLysinC, VitaCforte and
LysinC Drink mix are sold by a company owned by Stichting
Administratiekantoor Dr. Rath Holding, to whose companies group the
sponsor of the study also belongs, and therefore there are
commercial and financial implications associated with this case
report.
Based on the decision of the Editor, we wish to
publish this corrigendum to highlight these issues. Furthermore,
the limitations detailed above have been added to the online
version of the paper as a note added post-publication for the
printed record, and a competing interest statement concerning the
potential conflict of interest has also been added to the
Declarations section. Note that the following authors (Aleksandra
Niedzwiecki and Matthias Rath) have agreed to the publication of
this corrigendum; the other authors proved not to be contactable by
the corresponding author.
