Mayo Clinic Study Shows Complementary And Alternative Medicine Can Help In The Treatment Of Gastrointestinal Symptoms In Long COVID
: The emergence of the novel coronavirus SARS-CoV-2 in 2019 led to the declaration of a global pandemic by March 2020, subsequently named COVID-19. While the majority of COVID-19 patients experience symptom resolution within a few weeks of initial infection, a subset of individuals continues to grapple with persistent symptoms for more than four weeks, a phenomenon termed "Long COVID." Among the diverse range of symptoms exhibited by Long COVID patients, gastrointestinal (GI) symptoms are particularly common, including abdominal pain, diarrhea, and loss of appetite.
A new study conducted by Mayo Clinic in Rochester, USA, sheds light on the potential efficacy of complementary and Alternative Medicine
(CAM) for addressing the GI symptoms associated with Long COVID.
The Quest for Effective Long COVID Management
The challenges posed by Long COVID are manifold. With a lack of standardized treatment strategies, the medical community has been exploring various avenues to alleviate the chronic disturbances faced by these patients. A promising frontier for potential relief lies within the realm of CAM, a collection of healthcare systems, practices, and therapies that fall outside the conventional medical paradigm. CAM therapies, often employed as complementary or alternative to standard treatments, encompass diverse modalities such as nutritional supplements, herbal medicine, psychological interventions like mindfulness, physical therapies including massage, and even holistic practices like yoga and acupuncture.
The Role of CAM in Acute COVID-19
Interestingly, CAM therapies have already demonstrated effectiveness in managing acute COVID-19 infections. Studies have highlighted the potential of CAM in reducing the severity and duration of upper respiratory symptoms, thus offering hope for their role in treating the lingering symptoms of Long COVID. Zinc, elderberry extract, probiotics, and other nutritional supplements have shown promise in ameliorating symptoms of viral infections. Moreover, techniques like Qigong and acupressure have exhibited positive effects in improving lung function and reducing hospital stays in severe COVID-19 cases.
The Long COVID Conundrum
Long COVID presents a unique challenge due to its persistent nature and the diverse range of symptoms it encompasses. GI symptoms, including abdominal pain, diarrhea, and loss of appetite, are particularly burdensome for affected individuals. Despite the prevalence of these symptoms, there has been a dearth of effective treatment strategies. The Mayo Clinic study aimed to bridge this gap by evaluating the potential of CAM therapies in addressing GI symptoms associated with Long COVID.
The Mayo Clinic Study: Unveiling CAM's Potential
The study conducted by Mayo Clinic, situated in Rochester, USA, was a systematic review of existing literature related to CAM's effectiveness in treating GI symptoms of Long COVID. The study's methodology involved comprehensive searches across five electronic databases, spanning from January 2019 to November 2022. The selected studies underw
ent rigorous assessment by independent reviewers, ultimately resulting in four studies (three case reports and one case series) being included for final review.
Results of the systematic review were intriguing, as they revealed a promising trend. The chosen studies showcased the potential benefits of CAM interventions in alleviating GI symptoms of Long COVID. Two studies employed nutritional supplements, while the remaining two incorporated traditional Chinese medicine (TCM) modalities. Reductions in symptoms such as nausea, diarrhea, acid reflux, and abdominal discomfort were consistently reported in the reviewed studies.
CAM Modalities in Focus
The nutritional supplement studies underscored the potential of botanical-based, high-fiber formulas and oral lactoferrin formulations. Both approaches exhibited symptom resolution in the context of Long COVID-associated GI distress. The high-fiber formula study suggested a potential link between treatment and shifts in the gut microbiota, highlighting the role of the gut microbiome in the manifestation of Long COVID symptoms.
Lactoferrin, on the other hand, boasts anti-inflammatory and anti-viral properties, making it a compelling candidate for addressing the ongoing inflammatory response associated with SARS-CoV-2.
TCM also emerged as a promising contender, with studies employing herbal medicine and acupuncture yielding positive outcomes. Both studies reported complete symptom resolution in treated patients, further emphasizing the potential of CAM in providing relief to Long COVID sufferers.
Looking Ahead: Implications and Future Research
While the Mayo Clinic study presents a pioneering exploration into the role of CAM in addressing GI symptoms of Long COVID, certain limitations need to be acknowledged. The studies reviewed were predominantly non-experimental, hampering definitive conclusions about CAM's efficacy in this context. Furthermore, the limited number of participants and the absence of control groups in the studies raise questions about the generalizability of the findings.
The study's significance, however, lies in its potential to pave the way for more comprehensive and rigorous research in this domain. As our understanding of Long COVID evolves, CAM therapies could potentially contribute to a holistic management approach for this complex condition. Moreover, the study highlights the need for randomized controlled trials to systematically evaluate the safety and effectiveness of CAM interventions, thereby offering more evidence-based options for Long COVID patients.
In the face of the persistent challenges posed by Long COVID, the Mayo Clinic study underscores the potential of CAM therapies in ameliorating GI symptoms associated with this condition. As a pioneering systematic review in this area, the study provides a stepping stone for further research and exploration. CAM's potential, harnessed through nutritional supplements and traditional Chinese medicine modalities, hints at a promising avenue for holistic management.
As the medical community continues to unravel the complexities of Long COVID, CAM's potential to provide relief and enhance the quality of life for affected individuals is becoming increasingly evident. While the study's findings are promising, the journey ahead involves delving deeper into the mechanisms of action, conducting well-designed clinical trials, and ultimately integrating CAM therapies into a comprehensive framework for addressing the multifaceted challenges of Long COVID.
The study findings were published in the peer reviewed journal: Therapeutic Advances in Chronic Disease (Sage Journals)
