Outside experts weigh in
This news organization reached out to several outside experts for their perspective on the study.
Nancy Reau, MD, professor of internal medicine, associate director of solid organ transplantation, and section chief of hepatology. Rush University Medical Center, Chicago, noted that interventions to manage and prevent muscle cramps are “important, as cramping is common in cirrhosis and strongly affects quality of life.”
Dr. Reau cautioned that while pickle juice “sounds benign, it does have a lot of salt. Despite the salt content, this study didn’t show any difference between patients with and without ascites.
“However, cramping is more common in our patients with sarcopenia and those on diuretics for fluid management and it would be easy to see how this might impact fluid management,” Dr. Reau noted.
“Given that it is the acid (not the salt) in the pickle juice, there might be low salt alternatives,” Dr. Reau said.
Echoing Dr. Reau, Ankur Shah, MD, division of kidney disease and hypertension, Brown University, Providence, R.I., noted that “overuse of pickle juice could place patients at risk of developing high blood pressure and fluid overload, and pickle juice should be included in the sodium restriction guidance given to patients with high blood pressure and heart failure.”
In this study, however, the individual dose consumed was low, Dr. Shah noted.
He said the study “elegantly provides evidence to support the practice of sipping pickle juice for cramping.”
The authors should be “applauded for studying a simple solution with the most rigorous of methodologies, a randomized controlled trial,” Dr. Shah added.
“This simple treatment may be helpful to patients far beyond those with just cirrhosis, and expect future studies to explore this treatment in other populations,” Dr. Shah said in an interview.
Paul Martin, MD, chief of the division of digestive health and liver diseases and Mandel Chair in Gastroenterology, University of Miami, noted that, while muscle cramps can have a major impact on quality of life, “in terms of some of the other complications of cirrhosis that health care providers are dealing with, they may seem relatively innocuous, but obviously patients have a slightly different interpretation because of the effect cramps can have on sleep and so on.
“There have been a variety of home remedies to treat muscle cramps, but this study is intriguing as it suggests that pickle juice, which is freely available, helps mitigate the severity of the cramps. However, it’s unclear whether it prevents cramps,” Dr. Martin said in an interview.
Given that the study is getting traction on Twitter, Dr. Martin encouraged health care providers to be aware of the study and prepared to answer questions from patients.
The study had no specific funding. Dr. Tapper has served as a consultant to Novartis, Axcella, and Allergan, has served on advisory boards for Mallinckrodt, Bausch Health, Kaleido, and Novo Nordisk, and has received unrestricted research grants from Gilead and Valeant. Dr. Reau, Dr. Shah, and Dr. Martin have disclosed no relevant financial relationships.
