Chelation for autism spectrum disorder (ASD)

Abstract: This review included data from only one study, which had methodological limitations. As such, no clinical trial evidence was found to suggest that pharmaceutical chelation is an effective intervention for ASD. Given prior reports of serious adverse events, such as hypocalcaemia, renal impairment and reported death, the risks of using chelation for ASD currently outweigh proven benefits. Before further trials are conducted, evidence that supports a causal link between heavy metals and autism and methods that en… Show more

“…Although, there is no evidence of the efficacy and potential side effects of this chelation therapy in ASD, the heavy metal ratio is quite high in ASD patients and thus, it is suggested that there is a relationship between the heavy metals ratio and ASD (Pelch et al 2019). However, reviewers of the chelation therapy concluded that this treatment is not recommended for individuals with ASD, and that risks associated with chelation therapy outweigh any potential benefits (Davis et al 2012;James et al 2015;DeFilippis 2019). Chelation agents can bind ions nonspecifically, and thus cause a decrement in the plasma levels of calcium, iron, and magnesium as well.…”

“…Chelation agents can bind ions nonspecifically, and thus cause a decrement in the plasma levels of calcium, iron, and magnesium as well. This may associated with hypertension, hypotension, cardiac arrhythmias, and hypocalcemia, the latter of which can be fatal (James et al 2015;DeFilippis 2019). In this context, pharmacists can determine and monitor the problems related to the decreased levels of these ions, and can raise the awareness of the patients in relation to the symptoms of these deficiencies.…”

“…Thus, we included 17 systematic reviews. 4,[10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] Results from systematic reviews A summary of each systematic review is presented narratively below. In addition, Table 2 4,10-25 presents the issues addressed, the main findings from each systematic review and the quality of the evidence (based on the GRADE approach).…”
