Systematic Review of Alternative Treatments for Infantile Colic
Understanding Infantile Colic
Infantile colic is a distressing condition that impacts up to 20% of infants globally. Despite its prevalence, the exact nature and causes of colic remain unclear. Conventional treatments for this condition often lack robust evidence to justify their effectiveness, raising questions about their reliability.
Purpose of the Systematic Review
This uncertainty surrounding infantile colic prompted a systematic review focusing on complementary and alternative treatments, recently published in the journal *Systematic Reviews*. Researchers from the National Institute for Health Research (NIHR) at the University of Bristol and the University of Manchester conducted a thorough examination of the existing literature to consolidate relevant studies.
Key Complementary and Alternative Therapies
The review identified four primary therapies that have garnered attention in research: spinal manipulation, herbal medicines, acupuncture, and probiotics.
Spinal Manipulation
The findings on spinal manipulation showed generally positive outcomes; however, many included studies suffered from poor quality. Common issues included a lack of blinding for parents or outcome assessors, which could introduce bias. Higher-quality studies indicated that spinal manipulation may not be effective.
Herbal Medicines
Herbal remedies, such as peppermint oil and fennel, were suggested as potential treatments for colic. Nonetheless, the review concluded that there is insufficient evidence to endorse these recommendations. Fennel appeared to be the most promising among herbal options, but studies demonstrating its benefits were statistically weak, frequently crossing the threshold of no-effect. Therefore, it is challenging to definitively affirm fennel’s efficacy in treating colic.
Acupuncture
Acupuncture similarly showed some potential benefits; however, this evidence was also derived from poorly executed studies. Much like spinal manipulation, the perceived benefits seemed largely dependent on unblinded trials.
Probiotics
Probiotics emerged as the most substantiated treatment option, with several studies indicating a reduction in crying and fussing among infants. Despite this, the quality of evidence remains a concern, warranting caution regarding their use.
Safety and Efficacy of Treatments
While none of the therapies demonstrated strong effectiveness, the review highlighted that most complementary and alternative treatments, excluding acupuncture, exhibited minimal adverse effects. The adverse events associated with acupuncture were relatively minor, such as bleeding at the acupoint.
Implications for Clinical Practice
Infantile colic is a poorly understood condition characterized by non-specific symptoms and vague diagnostic criteria, with an unknown underlying cause. This complexity makes it a challenging target for pharmaceutical development, leading to a rise in complementary and alternative therapies. However, this review underscores the lack of compelling evidence supporting their effectiveness.
The review’s results suggest that while these therapies have not been proven effective, they are generally considered safe. Furthermore, it highlights the issues contributing to the treatment gap for infantile colic. Notably, although many associate infantile colic with gastrointestinal disturbances, such symptoms are not part of the latest diagnostic criteria, which simply define colic as an infant who is excessively crying.
