ABSTRACT

Objective:To study the clinical characteristics and prognosis of Brucella and other pathogens infections complicated with anti-myelin oligodendrocyte glycoprotein-IgG associated disorders (MOGAD). Methods:The clinical data of a patient with brucellosis complicated with MOGAD diagnosed in the Department of Neurology of the First Affiliated Hospital of Zhengzhou University in April 2022 were reported, and related case reports of infection coexisting with MOGAD were reviewed and summarized.Results:This case was a 44-year-old male, with recurrent fever and anorexia, followed by sudden weakness, numbness, pain in both lower limbs and dysuria, and then pain in the right neck. Magnetic resonance imaging showed lesions in the spine and spinal cord. Due to the positive myelin oligodendrocyte glycoprotein antibodies in cerebrospinal fluid and serum, and the growth of Brucella in blood culture, he was diagnosed as brucellosis complicated with MOGAD. After anti-brucellosis and glucocorticoid therapy, his symptoms improved. The literature on infection coexisting with MOGAD was reviewed and 22 cases were included. The infection sources included COVID-19, Borrelia burgdorferi, etc. No case of Brucella infection complicated with MOGAD had been reported. The main clinical manifestations of the 22 cases included myelitis (63.6%, 14/22), optic neuritis (40.9%, 9/22), acute disseminated encephalomyelitis (18.2%, 4/22), multiphasic disseminated encephalomyelitis (4.5%, 1/22) and meningoencephalitis (4.5%, 1/22). Magnetic resonance imaging was performed in 20 cases, showing spinal cord lesions in 12 cases (60.0%, 12/20), intracranial lesions in 10 cases (50.0%, 10/20) and optic nerve lesions in 6 cases (30.0%, 6/20). Cerebrospinal fluid examination was performed in 19 patients, of whom 13 (13/19) had increased cerebrospinal fluid cell count and 10 (10/18) had increased cerebrospinal fluid protein. Twenty-two patients received glucocorticoid therapy, of which 95.5% (21/22) responded well and 95.5% (21/22) had a good prognosis. Conclusions:Brucella and other pathogens infection may complicate with MOGAD, with similar clinical manifestations, and glucocorticoid therapy is effective.

ABSTRACT

@#Recent study demonstrated that insulin-like growth factor-1(IGF-1) could have benefits to improve the learning memory.Exercise can increase IGF-1 level in hippocampus.IGF-1 may mediate exercise inducing learning memory;one of the possible mechanism is that the IGF-1 and brain derived neurotrophic factor(BDNF) has a common regulatory capacity over calcium/calmodulin-dependent protein kinase Ⅱ(CAMKⅡ),mitogen-activated protein kinase Ⅱ(MAPKⅡ) and synapsin-1,and the convergence of multiple signaling pathways mediate synaptic plasticity and improve learning memory.
