Covid-19 vaccines and neurological complications: a systematic review.

The COVID-19 mainly causes respiratory disorders with high infection and severe morbidity and mortality. Neurologists have concerns about potential neurological side effects, profits, and timing of COVID-19 vaccines. This study aimed to review systematically research for the COVID-19 vaccine and neurological complications. Data was searched in Scopus, ISI web of knowledge, Medline, PubMed, Wiley, Embase, International Clinical Trials Registry Platform and Clinical Trials, Cochrane Library, and Google Scholar. Two reviewer authors individually searched and assessed the titles and abstracts of all articles. The third reviewer resolved disagreement between them. Data were documented regarding study location, study design, type of complications, number of patients, various types of COVID-19 vaccine, and type of neurological complications. Six studies in COVID-19 vaccine and neurological complications include two studies about neurological manifestations after the mRNA vaccines, four records about side effects of vector-based vaccine were included in the study. The main neurological complication associated mRNA vaccines were body aches, paresthesia, and difficulty walking, erythema migrans lesion, fatigue, myalgia, and pain in the left lateral deltoid region. The major neurological complication related to vector-based vaccines were urinary retention difficulty, feeding and ambulating, arm soreness, mild fatigue, chills, left-sided facial droop, headaches, a generalized epileptic seizure, hemianopia, and mild aphasia, acute somnolence and right-hand hemiparesis, acute transverse myelitis, deep vein thrombosis in her left leg, a vigilance disorder and a twitching, a severe immobilizing opsoclonus myoclonus syndrome, and encephalitis. A large spectrum of severe neurological unfavorable has been reported. These complications could occur as a result of molecular stimulation and later neuronal damage. Generally, the advantages of COVID-19 vaccination are dominant on the risks of a neurological complication at both individual and population levels. Future investigations will be required to find any relationship between neurological complications and COVID-19 vaccines principally as new strains of the virus and new vaccines are technologically advanced against them.

Neurological symptoms of COVID-19 infection; a cross-sectional study on hospitalized COVID-19 patients in Iran.

BACKGROUND: Coronavirus disease 2019 (COVID-19), a global issue now, can have a variety of clinical manifestations. Hundreds of articles have discussed different aspects of this infectious disease, such as physiopathology, epidemiology, clinical manifestations and treatment protocols. Recently, neurological manifestations of the disease have been found to be pretty common among COVID-19 patients. Here, neurological symptoms of COVID-19 infection with a focus on non-cerebrovascular complications are discussed in a large study population. METHODS: Neurological symptoms of 891hospitalized COVID-19 patients from March to June 2020 in a major Hospital, Tehran, Iran, were reviewed. Demographic characteristics and neurological manifestations were analyzed. RESULTS: Among 891 hospitalized COVID-19 patients, the following symptoms were observed: headache (63.9%), sleeping problems (51.3%), hyposmia/anosmia (46%), dizziness (45.4%), hypogeusia (42.1%), memory issues (31.5%), auditory disturbances (17.5%), paralysis (3.7%) and seizures (1.7%). In 29.7% of the patients, a neurological symptom was the initiating symptoms of the infection. Females were more likely to show headache and dizziness compared to males (p value<0.05). Headache intensity was also higher in females compared to males (p value<0.05). Headache prevalence was lower in older patients (p value<0.05), while memory loss and impaired consciousness were higher by increasing age (p values=0.002 and 0.001, respectively). CONCLUSION: Neurological manifestations were common among COVID-19 patients under study. Headache, as the most common neurological symptom among COVID-19 patients, was the most prevalent and intense among the female population. Headache, dizziness, sleeping problems, hyposmia/anosmia and hypogeusia were common COVID-19 neurological manifestations, while memory issues, auditory disturbances, paralysis, and seizures were less common.

Cutaneous manifestations related to the COVID-19 pandemic: a review article.

BACKGROUND: Skin lesions are either caused by COVID-19 disease or they can be due to other driving forces related to the COVID-19 pandemic. AIM: Considering the fact that the reported data in different articles for the type and prevalence of skin manifestations related to the COVID-19 pandemic are inconsistent, we have described the mechanism and type of skin lesions related to the COVID-19 pandemic. METHODS: In this review article, we have searched the Medline database (PubMed) for the combination of the following key terms "Dermatological Manifestation", "cutaneous Manifestation", "Skin Manifestation", "COVID-19", "SARS-CoV-2". RESULTS: The prevalence of skin manifestations related to COVID-19 ranged from 0.2% to 20%. The majority of these skin lesions are maculopapular eruptions. The skin presentations related to the COVID-19 pandemic are described below. Traumatic skin conditions such as dermatitis in individuals, especially those with allergies, might initiate secondary to over-washing or rinsing with inappropriate detergents. Also, inappropriate use of personal protective equipment (mask-gloves-shield) can trigger skin lesions on the face and hands or aggravate the lesions of acne, seborrhoeic dermatitis, eczema, etc. Furthermore, cutaneous adverse drug reactions may occur during hospitalization or outpatient treatment of COVID-19 patients. Also, psychocutaneous disorders due to acute stress can trigger or deteriorate several skin manifestations. Moreover, COVID-19 prevalence and course may be changed in patients with autoimmune or chronic inflammatory underlying skin disorders such as psoriasis, lupus erythematosus, pemphigus, scleroderma who are on immunosuppressive or biological medications to control their disorders. CONCLUSION: Due to the various dimensions of skin organ involvement and the large population affected, long-term skin conditions following this pandemic can be a lot more problematic than it appears. Serious preventive measures and medical supports are necessary to avoid skin disorders from becoming permanent or even chronic.

Guillain-Barré syndrome associated with COVID-19: a case report study.

Acute respiratory distress syndrome (ARDS) caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) is spreading around the world. Patients with coronavirus disease 2019 (COVID-19) typically present fever, cough, and respiratory illnesses. It has been revealed that the comorbidities can turn it into severe types, and the managements meet unpredicted complications. Here, we report a case of coronavirus disease 2019 (COVID-19) coincidence with confirmed acute Guillain-Barré syndrome (GBS). Ten days after admission and therapeutic process, the patient developed autonomic dysfunction. Despite respiratory support and receiving intravenous immunoglobulin, the patient died due to cardiac arrest. Albeit it is yet scientifically doubtful, there are raising concerns toward a possible association between GBS and SARS-CoV-2 infection, demonstrating potential neurological symptoms of COVID-19.

A case report of simultaneous autoimmune and COVID-19 encephalitis.

COVID-19 encephalitis is a rare condition usually presenting with altered mental status. Simultaneous presence of anti-NMDAR antibody and SARS-CoV-2 virus in CSF is a very rare condition described in a few case reports so far. On the other hand, brain edema is an unusual presentation of anti-NMDAR encephalitis. Herein, we reported a case with simultaneous detection of anti-NMDAR antibody and SARS-CoV-2 virus in her cerebrospinal fluid (CSF) presenting with brain edema, altered mental status, seizures, and respiratory symptoms.
