American Academy of Neurology (AAN): Annual Meeting 2019

Professional soccer players may be at increased risk of amyotrophic lateral sclerosis (ALS), according to Italian researchers who reviewed trading cards of about 25,000 male professional soccer players who played in Italy. The researchers then scanned news reports to find which of those players developed the rare neurologic disease. Players who developed ALS were a much younger age at diagnosis when compared with the general population, according to the researchers, who will present their findings at the annual meeting of the American Academy of Neurology.

While the findings might implicate professional-level soccer in the development of ALS, there could be other factors at work, said lead author Ettore Beghi, MD, of the Mario Negri Institute for Pharmacological Research, Milan. “Repeated traumatic events, heavy physical exercise, and substance use could also be factors in the increased ALS risk among soccer players,” Dr. Beghi said in a news release. “In addition, genetics may play a role.”

The ALS-related deaths of several Italian pro soccer players sparked suggestions that the disease and the sport could be somehow linked, according to Dr. Beghi and colleagues. To determine whether professional soccer players are at increased ALS risk, they reviewed the archives of the country’s major soccer card publisher from the years 1959 to 2000, recording the name, date, and place of birth; field position; and team history for the tens of thousands of players they identified.

News reports revealed that 33 players in that cohort developed ALS, compared with 17.6 cases that would be expected based on Italian general population estimates, according to Dr. Beghi and colleagues.

The number of cases per 100,000 person-years was 1.9 for all the soccer players, and 4.7 for those who were younger than 45 years at diagnosis, researchers said. In general, soccer players were younger at diagnosis, with a median age of ALS onset of 43.3 years, versus 62.5 years in the general population, they added.

These findings cannot be applied to those who play soccer below the professional level, since only professional athletes were studied, Dr. Beghi said. Moreover, the results should not be construed to suggest that people avoid playing soccer, he said, adding that the researchers had few specific details on the players’ ALS diagnoses.

Patients with ALS more often report head injuries, compared with the general population, while links between exercise and ALS have been found in some studies, but not others, according to the researchers.

“Clinical and experimental observations suggest an association between ALS and use of nonsteroidal anti-inflammatory agents and dietary supplements, including branched chain amino acids,” researchers added in the abstract for their report.

The study by Dr. Beghi and colleagues was supported by the Mario Negri Institute in Milan.

High body mass index (BMI) is associated with reduced mortality and reduced disability after acute ischemic stroke, according to research that will be presented at the annual meeting of the American Academy of Neurology.

“One possible explanation is that people who are overweight or obese may have a nutritional reserve that may help them survive during prolonged illness,” said Zuolu Liu, MD, of the University of California, Los Angeles, in a press release. “More research is needed to investigate the relationship between BMI and stroke.”

The obesity paradox was first noted when studies suggested that being overweight improved survival in patients with kidney disease or heart disease. Investigators previously examined whether the obesity paradox is observed in stroke, but their studies were underpowered and produced ambiguous results.

Dr. Liu and colleagues sought to evaluate the relationship between BMI and 90-day outcomes of acute ischemic stroke. They examined data for all participants in the FAST-MAG trial, which studied whether prehospital treatment with magnesium improved disability outcomes of acute ischemic stroke. Dr. Liu and colleagues focused on the outcomes of death, disability or death (that is, modified Rankin Scale score of 2-6), and low stroke-related quality of life (that is, Stroke Impact Scale score less than 70). They analyzed potential relationships with BMI univariately and in multivariate models that adjusted for 12 prognostic variables, such as high blood pressure, high cholesterol, and smoking.

Dr. Liu’s group included 1,033 participants in its study. The population’s mean age was 71 years, and 45.1% of the population was female. Mean National Institutes of Health Stroke Scale (NIHSS) score was 10.6, and mean BMI was 27.5 kg/m².

The investigators found an inverse association between the risk of death and BMI. Adjusted odds ratios for mortality were 1.67 for underweight participants, 0.85 for overweight participants, 0.54 for obese participants, and 0.38 for severely obese participants, compared with participants of normal weight. Similarly, the risk of disability had a U-shaped relationship with BMI. Odds ratios for disability or death were 1.19 for underweight participants, 0.78 for overweight participants, 0.72 for obese participants, and 0.96 for severely obese participants, compared with participants of normal weight. This relationship was attenuated after adjustment for other prognostic factors, however. Dr. Liu’s group did not find a significant association between BMI and low stroke-related quality of life.

The study was limited by the fact that all participants were from Southern California, which potentially reduced the generalizability of the results. The racial and ethnic composition of the study population, however, is similar to that of the national population, said the researchers.

No study sponsor was reported.
