ABSTRACT

SESSION TITLE: Autoimmune Disorders: Both Primary and Secondary SESSION TYPE: Rapid Fire Case Reports PRESENTED ON: 10/18/2022 10:15 am - 11:10 am INTRODUCTION: SARS-CoV-2 has demonstrated an impact on the lungs, leads to hypercoagulable states, and has caused immune-mediated reactions. Myasthenia Gravis (MG) represents a neuromuscular junction autoimmune disorder, with only a few case reports associated with new-onset MG following COVID-19 vaccination. Very rarely, MG has been reported in coexistence with Primary Sjogren's Syndrome (PSS). Here we present a case of new-onset MG in a patient with a positive COVID-19 a nasopharyngeal RT-PCR swab test, who received 3 doses of the Moderna COVID-19 vaccine with the latest dose 2 weeks prior to presentation and demonstrated positive PSS antibodies (Abs). CASE PRESENTATION: A 67-year-old male with no known past medical history presented with complaints of progressive weakness for 2 weeks, which began as diffuse malaise, and progressed to upper and lower extremity weakness with associated neck weakness, and dysphagia. Physical exam was remarkable for bilateral ptosis and difficulty ambulating. The patient was admitted to the ICU for suspected new-onset neuromuscular junction disorder and for close monitoring of his respiratory function. COVID-19 PCR was positive. MG and autoimmune disease workup was sent along with COVID-19 antibody testing. Chest X-Ray, CT head, and CT thorax were unremarkable. The patient was started on Pyridostigmine and IVIG, with low dose prednisone initiated on day 3 of admission. On the fifth day, symptoms improved significantly. Antibodies (Ab) against Acetylcholine (Ach) receptors were elevated and the diagnosis of MG was made. PSS Abs were also detected. Lyme, HIV, RPR, thyroid, and B12 levels were within the normal range which may mimic NMJ dysfunction. DISCUSSION: MG represents an autoimmune disorder due to autoantibodies against nicotinic AChR at the neuromuscular junction;however, these Abs can also target non-AChR muscle-specific receptor tyrosine kinase (MUSK). The exact mechanism of the autoimmune response with MG is not fully understood;however, there have been associations found with thymus gland hyperplasia and neoplasm when anti-AChR Abs are involved. Genetic predisposition is also likely to play a role. Viral and bacterial infections are established triggers for a myasthenic crisis in patients with pre-existing MG;however, there is yet to be a clear consensus regarding infections causing MG in otherwise healthy patients. As our pt did receive the COVID-19 vaccine, we have to consider an autoimmune reaction secondary to his administration. CONCLUSIONS: COVID-19 vaccines have demonstrated autoimmune responses such as myocarditis and myasthenic crisis in individuals. There have also been documented cases of MG in symptomatic COVID-19 infections. Given these findings, this patient may have experienced an environmental insult on top of a genetic predisposition and may warrant further investigation in patients with similar presentations.

ABSTRACT

BACKGROUND AND AIM: In this study, we aimed to examine the changes in Neutrophil/Lymphocyte ratio (NLR), C-Reactive Protein (CRP), Ferritin, Lactate Dehydrogenase (LDH), D-Dimer and Systemic immune inflammation index (SII) parameters according to age and gender in patients with COVID-19 infection. METHODS: A total of 322 inpatients (Female: 180, Male: 142) who applied to Lokman Hekim University Ankara Hospital between March 2019 and August 2021 and had positive PCR tests were included in the study. The patients were divided into five age groups (1st group: 1-17 years;2nd group: 18-30 years;3rd group: 31-45 years;4th group: 46-60 years;5th group: 61-92 years). Laboratory results and demographic findings of PCR-positive patients were reviewed retrospectively. WBC, NLR, CRP, Ferritin, LDH, D-Dimer, SII values of the patients included in the study were examined in the study. RESULTS: When NLR, CRP, Ferritin, LDH, D-Dimer parameters were evaluated according to age groups, there was a significant difference (p<0.05). When the first and 2nd groups were compared, there was a significant difference in the D-dimer level. When the first and 3rd groups were compared, there was a significant difference in LDH, WBC, CRP levels. When the first and 4th groups were compared, there was a significant difference in the CRP levels. When the first and 5th groups were evaluated, a significant difference was observed in the levels of Ferritin, NLR, and CRP (p<0.05). When the correlations of NLR, CRP, Ferritin, LDH, D-Dimer values with respect to age were examined, CRP, LDH and Ferritin levels showed a moderate correlation (r=0.557, r=0.408, r=0.400, respectively);No correlation was observed in NLR, D-Dimer and WBC values. When evaluated according to gender, infection-related parameters (CRP, NLR, WBC and Ferritin) were found to be higher in males (p<0.05). When SII values were evaluated according to age and gender, no significant difference was observed (p>0.05). CONCLUSIONS: Since inflammatory and prognostic markers vary in patients with COVID-19 infection, we think that it would be useful to evaluate WBC, NLR, CRP, Ferritin, LDH, D-Dimer parameters and demographic data together for the follow-up of infection.

ABSTRACT

COVID-19 is the most devastating pandemic situation we have experienced in our age, affecting all systems. Although it affects all systems, it shows its most important effect through thrombophilia. Therefore, the possible cause of sudden death due to COVID-19 may be embolism caused by thrombophilia. D-dimer amounts increase due to COVID-19. The thrombosis is associated with sudden death in COVID-19 disease in populations. Since individuals with thrombophilia will be more prone to death due to COVID-19, it may be appropriate to administer low doses of Clexane (Enoxaparin sodium) or low-weight heparin for prophylactic purposes in order to consider these individuals at high risk and to prevent deaths. Moreover, in order not to risk the lives of healthcare professionals with thrombophilia, it would be appropriate to keep them away from individuals with COVID-19 disease and to employ them in different healthcare services according to their fields of expertise. It should also not be forgotten that different symptoms related to COVID-19 appear day by day, these different symptoms probably show that the virus has undergone mutations in order to survive, but no matter what, its effect on thrombophilia has not been eliminated yet. This compilation aims to present the reasons and causes of death due to COVID-19, possible treatment options, and thrombophilia panel tests and new parameters that may have a place in the meticulous interpretation of these tests and possible etiopathology in the light of current information. Therefore, presenting this information in a rational manner and keeping the parameters of the thrombophilia panel under strict control predict that the deaths due to the virus will be partially reduced.
