Late-Stage Lyme Illness and Psychiatric Sickness: Remaining Verdict?

Must read

Lyme neuroborreliosis (LN), a late-stage manifestation of Lyme disease, just isn’t related to an elevated threat of creating severe psychiatric sickness, outcomes of a giant, population-based examine counsel.

Nonetheless, a better share of sufferers with LN obtained anxiolytic, hypnotic, sedative, and/or antidepressant drugs throughout the first yr after LN prognosis — though the degrees at which these drugs had been prescribed returned to the degrees prescribed to the comparability cohort after the primary yr.

The findings “counsel that almost all signs related to the prognosis [of LN] subside inside a brief interval,” lead writer Malte M. Tetens, BMSc, a analysis assistant at Infektionsmedicinsk Afdeling, Rigshospitalet, Copenhagen, Denmark, instructed Medscape Medical Information.

“Whereas highlighting dangers related to illness is indisputably vital, reassurance when ailments are usually not that deleterious is simply as vital; and, primarily based on our examine, we should conclude that there is no such thing as a proof to counsel that sufferers with Lyme neuroborreliosis are at elevated threat of psychiatric illness,” he mentioned.

The examine was published online October 7 in JAMA Psychiatry.

Ongoing Concern

Tetens mentioned the examine was “prompted by research suggesting that Lyme neuroborreliosis is likely to be the reason for psychiatric problems, and though these research have some flaws, sufferers recognized with Lyme neuroborreliosis nonetheless fear concerning the affiliation.”

No nationwide population-based cohort examine incorporating long-term follow-up information has investigated the potential affiliation between LN and the chance of creating psychiatric ailments.

Tetens mentioned his workforce “felt obliged to make use of a longtime cohort to review whether or not Lyme neuroborreliosis is related to psychiatric problems, as our examine design supplies outcomes which are extra dependable than beforehand printed.”

To research the query, the researchers in contrast information on Danish residents (n = 2897) who had been recognized with LN (ie, they’d obtained a optimistic end result on the Borrelia burgdorferi intrathecal antibody check) for the primary time between January 1, 1995, and December 31, 2015, with information on an age- and sex-matched cohort (n = 16,460) of people who had not been recognized with LN.

For each teams, the median age was 45.7 years (interquartile vary, 11.5 – 62.0 years); 56.8% had been male. The 2 teams didn’t differ with regard to the proportion of members whose Charlson comorbidity index rating was >1.

In evaluating the LN cohort to the non-LN cohort, the researchers discovered no enhance within the total threat of creating psychiatric illness (hazard ratio, 1.1; 95% CI, 0.9 – 1.2).

Equally, through the first yr, there have been no variations between the LN and the comparability cohorts with respect to subcategories of psychiatric illness, similar to psychoactive substance use, temper affective problems, nervousness, obsessive-compulsive problems, extreme stress reactions, or adjustment problems.

A sensitivity evaluation that excluded members not born in Denmark yielded the identical outcomes.

The researchers calculated the proportion of every group who had some sort of hospital contact through the interval starting 10 years prior to review inclusion to fifteen years following examine inclusion, and there was no distinction between the cohorts (10.9% vs 10.2%).

Nevertheless, there have been notable variations through the first yr after examine inclusion between the LN cohort and the comparability cohort with respect to prescriptions for psychotropic drugs.

Psycholeptic 16.5% vs 9.9%; distinction, 6.6% (5.2% – 8.0%)
Anxiolytic 7.2% vs 4.7%; distinction, 2.6% (1.6% – 3.5%)
Hypnotic and sedative 11.0% vs 5.3%; distinction, 5.7% (4.5% – 6.8%)
Antidepressant 11.4% vs 6.0%; distinction, 5.4% (4.3% – 6.6%)


There have been no variations in prescriptions between the 2 cohorts for any of those drugs after 1 yr.

“It is very important emphasize that many questions stay unanswered, [and] absence of proof just isn’t proof of absence,” Tetens commented.

“Additional, our examine focuses on sufferers with Lyme neuroborreliosis and was not designed to guage the posttreatment Lyme illness syndrome,” he added.

Though the examine can not “lastly conclude” whether or not neuropsychiatric sequelae happen in affiliation with LN, the examine “means that it’s not an awesome downside,” mentioned Tetens.

Nevertheless, he added, the short-term affective signs of LN warrant additional investigation to evaluate the affiliation between the illness and the receipt of prescribed psychiatric drugs.

A World of Distinction

Commenting on the examine for Medscape Medical Information, Michael P. Koster, MD, director, Division of Pediatric Infectious Illnesses, and affiliate medical director, Division of Epidemiology and An infection Management, Rhode Island and Hasbro Youngsters’s Hospitals, Windfall, Rhode Island, described the examine as a “very good country-wide, case-matched cohort examine with a tremendous registry powered to assist reply the query of lingering neuropsychiatric signs in sufferers who’ve been recognized with neuroborreliosis.”

Koster, who can also be an affiliate professor of pediatrics on the Alpert Medical Faculty of Brown College in Windfall and was not concerned with the examine, mentioned that the “postinfectious syndrome is a troublesome illness course of to handle, as it may be very nonspecific, outdoors of the particular date of an infection, and might differ extensively between sufferers.”

He added that it “takes a caring doctor to know this syndrome and to assist the affected person overcome the postinfectious points, similar to ache from radiculopathy, sleep disturbances, arthralgias, depression, and psychological fogginess.”

Usually, “transdisciplinary care between an infectious illness professional, psychiatry, and presumably a ache specialist could make a world of distinction for a affected person struggling the implications of a postinfectious course of,” he famous.

He emphasised {that a} “caring and compassionate demeanor from the treating doctor might imply the distinction between supportive care vs unwarranted and dangerous additional antibiotic remedy.”

Clinicians must be “be prepared to succeed in out to psychological well being suppliers of their space for help within the remedy of sequelae from these kind of infections,” mentioned Koster.
