MS Diagnoses Linked to Other Health Problems
Is MS a 'lifestyle disease'?

Reporter, VICE News/MedPage Today

Health records from the Canadian provinces of Quebec, Nova Scotia, Manitoba, and British Columbia indicated that those with MS were, at diagnosis, more likely to have every comorbidity examined except for hyperlipidemia, Ruth Ann Marrie, MD, PhD, of the University of Manitoba, and colleagues, reported in Neurology.

But the most common comorbidities among MS patients were fibromyalgia and depression, they found.
"The burden of psychiatric comorbidity for both sexes even at MS diagnosis was striking," the authors wrote. "While depression and anxiety are recognized to be common in established MS, our findings and those of prior studies collectively indicate that these conditions are the most or nearly the most common preexisting comorbidities at diagnosis, particularly among those aged 20-44 years."
Researchers looked at 23,382 MS cases and 116,638 age-, location-, and sex-matched controls, and found that people with MS were more likely to have the following, expressed as relative risks (all P<0.0001):

Hypertension: 1.17
Diabetes: 1.17
Ischemic heart disease: 1.30
Fibromyalgia: 2.87
Inflammatory bowel disease: 1.68
Epilepsy: 2.18
Depression: 2.04
Anxiety: 1.61
Bipolar disorder: 1.86
Schizophrenia: 1.32

For many of these conditions, dividing patients by gender produced even more pronounced results. For instance, women with MS had a 16% higher incidence of hypertension than women without MS. But men with MS had a 48% higher incidence of hypertension than those without MS. The researchers found similar results for several other comorbidities as well.

Although women with MS were expected to have higher rates of fibromyalgia and depression, the study authors did not anticipate that women with MS would have a 39% higher prevalence of chronic lung disease at MS diagnosis compared with non-MS women, or that men with MS would have only a 21% higher prevalence of chronic lung disease.

In an accompanying editorial questioning whether MS is a "lifestyle disease," William Grant, PhD, of the Sunlight Nutrition and Health Research Center, and Trond Riise, PhD, of the University of Bergen in Norway, wrote that the large number of cases and validated case definitions are both strengths of the study, but it lacks information on the extent of the comorbidities and other lifestyle issues, such as smoking.

They argued that many of the chronic diseases mentioned as comorbidities in the study could be tied to lifestyle risk factors, including low ultraviolet exposure, poor diet, and smoking.

"Nevertheless, the finding of a higher occurrence of a number of chronic diseases among patients with MS relative to the general population begs the question of whether there are shared risk factors for MS and these comorbid diseases," Grant and Riise wrote. "If so, recognizing them could lead to recommendations that would reduce the risk of both MS and the comorbid diseases."

Marrie said the idea for her series of MS comorbidity studies arose working with patients and wondering whether their other health problems were giving them more trouble than their MS. When she looked at the existing literature, she found mostly studies examining MS coupled with other immune-mediated diseases, but she wanted to know more.
"I worried about things like chronic bronchitis, shortness of breath walking across the room and fatigue," she told MedPage Today. "I decided I was going to try to figure this out."

Five years before patients were diagnosed with MS, the prevalence of all comorbidities was lower, records indicated. And as the patients with MS aged, they were more likely to have these comorbidities -- as is true of the general population with age.

Marrie and her team used administrative data collected in the four provinces. They excluded patients under 20 years old, which they say may have affected their results.
The investigators hypothesized that the comorbidities may be the result of shared genetic or environmental factors, but their presence before MS is diagnosed could actually increase the likelihood of an MS diagnosis because of increased surveillance by clinicians.

Depression and Other Chronic Conditions Common at MS Diagnosis

MINNEAPOLIS -- March 9, 2016 -- People newly diagnosed with multiple sclerosis (MS) may often have other chronic health conditions as well, according to a study published in the March 9, 2016, online issue of the journal Neurology.

“These findings are interesting for several reasons,” said Ruth Ann Marrie, MD, University of Manitoba, Winnipeg, Manitoba. “It raises the question of whether there are shared risk factors for both MS and these other diseases, and if so, whether we could eventually find ways to reduce the risk of both MS and the other diseases.”

“Also, studies have shown that MS may progress faster for people who also have other chronic conditions, so it’s important for people and their doctors to be aware of this and try to manage these conditions,” she added.

For the study, researchers examined how common several chronic conditions were in 23,382 people with MS at the time of their diagnosis and 116,638 people of the same age and sex without the disease. The conditions included high blood pressure, diabetes, high cholesterol, heart disease, chronic lung disease, epilepsy, fibromyalgia, inflammatory bowel disease, depression, anxiety, bipolar disorder and schizophrenia.

The people with MS had higher rates of all of the conditions except high cholesterol. The rates were especially high for mental illness. The most common condition was depression. At least 19% of those with MS had depression compared with 9% of those without the disease. As depression and anxiety can affect quality of life and can increase the risk of hospitalisation, the ability of people to be adherent to their medication regimens is important. Dr. Marrie said these conditions should be closely monitored.

For many of the conditions, the rates differed for men and women with MS. For men with MS, the rate of high blood pressure was 48% higher than for men without the disease: 22% of men with MS versus 15% of men without MS. For women with MS, the rate was 16% higher than for women without the disease (14% vs 12%).

Men with MS also had disproportionately higher levels of diabetes, epilepsy, depression, and anxiety than women with MS. Women with MS had disproportionately higher levels of chronic lung disease than men with MS.

Dr. Marrie said further study is needed about the differences between men and women and whether the safety of MS treatments differs for those with additional chronic illnesses.

In an accompanying editorial, William B. Grant, PhD, Sunlight, Nutrition and Health Research Center, San Francisco, California, wrote: “One possible reason for the finding is that these chronic illnesses and MS share many of the same risk factors. Smoking, obesity, low vitamin D, and low omega-3 fatty acids have been shown to contribute to the severity of MS and, in various combinations, these other illnesses as well. Doctors will want to stress to those with MS the importance of correcting these problems.”

It is important to note that the age of the people in the study when they were diagnosed was high and may not represent the MS population as a whole.

The researchers also looked at how common the conditions were 5 years before the people were diagnosed with MS and found that people who were later diagnosed with MS were still more likely to have the other conditions.
