Effects of PEA-LUT on Frontal Lobe Functions and GABAergic Transmission in Long-Covid Patients

Effects of Palmitoylethanolamide Co-ultramicronized With Luteoline (Pea-lut) on Frontal Lobe Functions and GABAergic Transmission in Long Covid Patients. An 8-week Randomized Controlled Trial.

The study explore the efficacy of PEA-LUT in patients suffering from neurological symptoms of Long-Covid

Aim of this study was testing the possible therapeutic effects of an 8-week therapy with PEA-LUT on GABAB-ergic neurotransmission, LTP-like synaptic plasticity, indexed with transient potentiation of motor evoked potentials (MEP) amplitude after repetitive TMS given as intermittent theta burst stimulation (iTBS) in long COVID patients with cognitive complaints and fatigue.

Inclusion Criteria:

• previous diagnosis of SARS-CoV-2 infection confirmed through detection of virus RNA by polymerase chain reaction (PCR) testing of a nasopharyngeal swab;
• subsequent recovery from infection as defined by two consecutive negative PCR tests separated by at least a day;
• mild form of COVID-19 (symptoms may include fever, cough, sore throat, malaise, myalgia, anorexia, nausea, diarrhoea, anosmia and ageusia) without necessitating hospital admission;
• complaints of cognitive difficulties and/or sense of fatigue, persisting after SARS-CoV-2 infection.

Exclusion Criteria:

• prior or concurrent diagnosis of neurological, psychiatric, endocrine, metabolic or cardiopulmonary conditions;
• clinical and/or radiological evidence of COVID-19 related pneumonia during the active phase of the disease;
• anaemia;
• current pharmacological treatment with corticosteroids, antihistamines, antihypertensives, diuretics, antidepressants, anxiolytic or hypnotic drugs at the time of study
