A 63-year-old Caucasian male, known case of controlled type 2 diabetes, chronic renal failure, and ischemic heart disease, was presented with weakness and loss of movement in lower limbs, an absent sensation from the chest below, constipation, and urinary retention. About 4 days before these symptoms, he experienced a flu-like syndrome. Suspicious for COVID-19, his nasopharyngeal specimen’s reverse transcription-polymerase chain reaction (RT-PCR) resulted positive. Chest X-ray and HRCT demonstrated severe pulmonary involvement. Immediately, he was admitted to the emergency ward, and the treatment was started according to the national COVID-19 treatment protocol. Subsequently, diagnostic measures were taken to investigate the patient’s non-heterogeneous peripheral (spinal) neuromuscular manifestations. Brain CT scan and MRI were normal, but spinal MRI with gadolinium contrast showed extensive increased T2 signal involving central gray matter and dorsal columns, extended from C7 to T12 with linear enhancement in the sagittal plane, posteriorly within the mid and lower thoracic cord. The CSF specimen demonstrated pleocytosis, positive RT-PCR for SARS-CoV-2, and elevated IgG index. Clinical presentation, MRI, CSF, and laboratory findings prioritized the acute transverse myelitis (ATM) as a probable complication of COVID-19 infection over other differential diagnoses. Intravenous methylprednisolone and, subsequently, IV human immunoglobulin were added to the treatment regimen. In the end, the complete resolution of dysesthesia, urinary retention, and constipation were achieved. After continuous and extended respiratory and motor rehabilitation programs, he was discharged asymptomatic.

Background: SARS-CoV-2 (COVID-19) is a new human pathogen, and currently, the world has been plagued by its pandemic and there are no specific treatment options, mostly affects the respiratory system, ranging from mild flu-like symptoms to severe acute respiratory syndrome (SARS), but extra respiratory multi-systemic involvement has also been reported.Case presentation: A 63-yr-old Caucasian male veteran (retired army colonel), known case of controlled Type 2 diabetes, chronic renal failure and ischemic heart disease, about 4 days after the onset of flu-like syndrome (with no trauma history) experienced loss of control over both lower limbs, absent sensation from the chest below with constipation and urinary retention. Due to world SARS-CoV-2 (COVID-19) outbreak, his nasopharyngeal specimen was tested for COVID-19 reverse transcription polymerase chain reaction (RT-PCR) and positive result obtained. Chest x-ray and HRCT suggested severe pulmonary involvement. Immediately, he was admitted at emergency ward, treated based national COVID-19 protocol and a series of diagnostic procedures were started up to find out the cause of his non-heterogeneous peripheral (spinal) neuromuscular manifestations. Brain CT scan and MRI were normal, but spinal MRI with gadolinium contrast agent showing extensive increased T2 signal involves central grey matter and dorsal columns, extension between C7 and T12 with linear sagittally oriented enhancement posteriorly within the cord in the mid and lower thoracic cord. The CSF specimen obtained from LP shown pleocytosis, positive RT-PCR for SARS-CoV-2 and elevated IgG index. Clinical presentations, MRI, CSF and laboratory findings, after ruled out the other numerous possible causes with specific methods, suggested the Acute Transverse Myelitis (ATM) as a probably complication of COVID-19 infection. Intravenous methylprednisolone and then human immunoglobulin was added to treatment regimen. At the end, complete resolution of dysaesthesia, urinary retention and constipation were achieved. After continuous and long respiratory and motor rehabilitation programs, he was discharged home asymptomatic. Conclusions: We believe that SARS-CoV-2 has a potential to produces different extra respiratory multi-systemic involvement as immune-mediated process and complexes, and this should be kept in mind whenever encounter a patient with acute onset of neurological manifestations, especially after microbial infections or vaccinations.

This systematic review and meta-analysis was conducted to evaluate the effect of COVID-19 on thyroid function and the role of thyroid hormones alterations in predicting the severity of COVID-19. Online databases, including Scopus, Medline/PubMed, EMBASE, Google Scholar, and Cochrane were searched up to August 2, 2022. After screening titles, abstracts, and full manuscripts, respectively, 30 reports were enrolled. The risk of bias (ROB) was evaluated using the QUADAS-2 tool. In addition, odds ratio (OR) and hazard ratio (HR) analysis for assessing the OR of abnormal thyroid function tests (TFT) in predicting the COVID-19 severity and poor outcomes. Among 30 enrolled studies, ROB of the current study is estimated low to moderate. The average number of patients in each study was 325 (range: 40-3,703), with an overall mean age of 57.6, and the female proportion of 40.4%. Overall, the pooled analysis showed that the prevalence of thyroid dysfunction among 9,707 COVID-19 cases was 15%. Among mild to moderate COVID-19 patients, 6.2% had abnormal TFT, and among patients who experienced severe to critical COVID-19, 20.8% had abnormal TFT. The pooled OR for abnormal TFT and the severity of COVID-19 obtained from 3,865 COVID-19 patients was 3.77 (2.03, 6.99). The pooled HR of TSH level of COVID-19 mortality was 1.57 (0.91, 2.72). Our results demonstrate a high prevalence of thyroid dysfunction in COVID-19, and that among patients severe cases had a 3.77-fold higher risk of abnormal TFT compared to mild to moderate COVID-19. Further studies are required to evaluate the longer-term prognostic role of thyroid dysfunction in severe COVID-19, and investigate potential therapeutic strategies.

A 56-year-old man was referred to the emergency department for the subacute onset of and weakness in the lower extremities, paraesthesia and pain. He was diagnosed with SARS-CoV-2 pneumonia and then, he received the necessary treatment according to national protocol. Radiographic, laboratory, and electroneurographic findings indicated an acute polyradiculoneuritis with prominent demyelination and suggesting the diagnosis of Guillain-Barr syndrome associated with COVID-19 infection.

Lacunar strokes occur when a branch of a large cerebral artery is blocked. The thalamus is often affected, causing uncontrollable motions. A 72-year-old previously healthy man presented with involuntary motions in the right limbs, which were present at rest, and exacerbated during voluntary actions. He had received the first dose of the adenoviral vector-based coronavirus disease 2019 vaccine (ChAdOx1 nCoV-19) 9 days ago. Severe thrombocytopenia and elevated levels of lactate dehydrogenase, ferritin, C-reactive protein, and D-dimer were found, without any evidence of connective tissue disease. Electromyography demonstrated typical choreiform movements, and the brain magnetic resonance imaging indicated a small high signal lesion on the left side of the thalamus. Detection of the immunoglobulin G antibodies against platelet factor 4 in the blood, negative heparin-induced platelet activation (HIPA) test, and positive modified HIPA test confirmed the thalamic stroke due to the vaccine-induced prothrombotic immune thrombocytopenia (VIPIT). He was admitted to the intensive care unit and received nadroparin, sodium ozagrel, edaravone, methylprednisolone, and haloperidol. His hemi-chorea improved gradually over 2 weeks, and he was discharged after 21 days with rehabilitation advice. VIPIT due to the ChAdOx1 nCoV-19 is a novel immune-mediated response that needs clinicians’ awareness and further investigations.

A 42-year-old man with coronavirus disease 2019 pneumonia was admitted to a small town hospital that did not have intensive care unit (ICU)-level resources available. Twelve hours later, the patient suddenly became agitated, and an extensive anterolateral ST-elevation myocardial infarction was detected by 12-lead electrocardiography and supported by a rise in serum cardiac enzymes. Low blood oxygen saturation (59%) and cardiac ejection fraction (ejection fraction = 20%) reflected criticality that could potentially require a catheterization laboratory, coronary artery bypass graft surgery, and ICU-level resources. After the coordination of physicians with the nearest equipped hospital and air medical crew, a Mil Mi-17 medical helicopter unit was dispatched. About 20 minutes before reaching the destination hospital, his clinical condition declined; his heart was 50 beats/min, his blood pressure was 75/40 mm Hg, and he had jugular vein distention. Muffled heart sounds, decreased electrocardiographic voltage, and the accumulation of pericardial effusion on a bedside ultrasound indicated cardiac tamponade. The air medical crew resuscitated the patient through the interventions of intubation, mechanical ventilation, administration of intravenous fluids, and initiation of an epinephrine infusion. Ultrasound-guided pericardiocentesis was performed in the helicopter, which kept him alive until pericardotomy could be performed at the destination hospital. Unfortunately, after pericardiotomy and coronary artery bypass graft surgery, the patient died 7 days later in the ICU due to severe cardiopulmonary failure.
