Anti-leucine rich glioma inactivated 1 (LGI1) autoimmune encephalitis (AE) is characterized by cognitive impairment or rapid progressive dementia, psychiatric disorders, faciobrachial dystonic seizures (FBDS) and refractory hyponatremia. Since December 2020, millions of people worldwide have been vaccinated against COVID-19. Several soft neurological symptoms like pain, headache, dizziness, or muscle spasms are common and self-limited adverse effects after receiving the COVID-19 vaccine. However, several major neurological complications, despite the unproven causality, have been reported since the introduction of the COVID-19 vaccine. Herein, we describe a 48 years old man presenting with rapidly progressive cognitive decline and hyponatremia diagnosed with anti LGI1 AE, occurring shortly after the second dose of mRNA COVID -19 vaccine and possibly representing a severe adverse event related to the vaccination. Response to high dose steroid therapy was favorable. As millions of people worldwide are currently receiving COVID-19 vaccinations, this case should serve to increase the awareness for possible rare autoimmune reactions following this novel vaccination in general, and particularly of anti-LGI1 AE.

ABSTRACT Polysulfated glycosaminoglycan (PSGAG) is a slow-acting disease-modifying agent used to treat degenerative joint disease. Although labeled for intramuscular use, it is commonly given by owners via a subcutaneous (SC) route. There is little information on adverse events related to SC administration or what other therapies are used concurrently with PSGAG. We hypothesized that SC PSGAG is perceived by owners as having minimal adverse events and that it would most often be given with other therapies. Owners (n = 378) were surveyed about their perceptions regarding SC PSGAG prescribed to dogs at one veterinary rehabilitation clinic. Complete surveys were provided for 69 dogs (two owners had multiple dogs). Overall, 13/69 (18.8%) dogs had an adverse event reported during the use of PSGAG. Most events were considered minor (stomach upset, loose stool, pain at injection site, fear) and did not lead to discontinuation of PSGAG. One dog experienced a moderate adverse event (persistent gastrointestinal symptoms) and one a severe adverse event (thrombocytopenia, bruising), which resolved after discontinuing PSGAG. PSGAG is most commonly administered along with other medications and rehabilitation therapies. The present study demonstrates that SC administration of PSGAG is well tolerated in most of the dogs, with primarily mild, self-resolving adverse events.

Background/Aim: The most severe adverse event of radiotherapy in lung cancer is radiation pneumonitis (RP). Some indices commonly used to prevent RP are evaluated based on the anatomical lung volume. The irradiation dose may be more accurately assessed by using functional lung volume. We evaluated the usefulness of computed tomography (CT) incorporating functional ventilation images acquired by the inhalation of xenon (Xe) gas (Xe-CT functional images). Patients and Methods: Two plans were created for twelve patients: volumetric modulated arc therapy (VMAT) planning using conventional chest CT images (anatomical plans) and VMAT planning using Xe-CT functional images (functional plans), and the dosimetric parameters were compared. Results: Compared to the anatomical plans, the functional plans had significantly reduced V20Gy in the high-functional lungs (p=0.005), but significant differences were not seen in the moderate-functional and low-functional lungs. Conclusion: The incorporation of Xe-CT functional images into VMAT plans enables radiotherapy planning with consideration of lung function.

Abstract Introduction: Antithyroid drugs (ATDs) are widely used for the treatment of hyperthyroidism. Most side effects of these medications are mild and emerge within the first months of treatment. In contrast, antineutrophil cytoplasmic antibodies (ANCA)-associated vasculitis is a severe adverse event whose occurrence increases with increasing time of treatment. Vasculitis is more frequently associated with propylthiouracil than with methimazole, but the latter has also been related to the occurrence of ANCA and even to clinically manifest vasculitis. Many patients develop ANCA during treatment with methimazole but do not exhibit signs/symptoms of vasculitis. Objective: We previously reported a relatively high frequency (20%) of ANCA in patients exposed to methimazole but none of them exhibited clinical manifestations of vasculitis on that occasion. We continued to follow up these patients with ANCA and report here their evolution after 2 years. Methods: Seventeen patients exposed to methimazole were followed for 2 years after antibodies detection (ANCA). Results: Eight patients had ANCA but had not used methimazole for at least 6 months. During the following 24 months, continuing without ATD, none of the patients developed clinically apparent vasculitis. In the last assessment, five patients no longer had ANCA, while these antibodies persisted in three. Nine patients had ANCA and had been on methimazole for at least 6 months. The medication was not immediately discontinued in these patients when the antibodies were detected. After this detection, treatment with methimazole was continued in these patients for more 3 months (n = 1), 6 months (n = 2), 9 months (n = 1), 12 months (n = 2), 18 months (n = 2), and 24 months (n = 1). During the 2 years of follow-up after the detection of ANCA, none of the 9 patients developed signs/symptoms of vasculitis. In the last assessment, ANCA were negative in two patients who had received methimazole for more 3 and 6 months and who were therefore without receiving the drug for 21 and 18 months, respectively. The other 7 patients remained ANCA positive. Conclusion: Although vasculitis is necessarily associated with the presence of ANCA, the inverse frequency is undefined and appears to be low. Thus, measurement of ANCA would not be recommended in asymptomatic patients during methimazole treatment and immediate discontinuation of this drug, if these antibodies are detected eventually, may not be required.

Background and Objectives: Researchers all around the world are working hard to find an effective treatment for the new coronavirus 2019. We performed a comprehensive systematic review to investigate the latest clinical evidence on the efficacy and safety of treatment with Remdesivir in hospitalized patients with COVID-19. Materials and Methods: We performed a systematic search in Pubmed, Embase, Web of Science, Google scholar and MedRxiv for relevant observational and interventional studies. The outcomes measures were mortality rates, improvement rates, time to clinical improvement, all adverse event rates and severe adverse event rates. Results: Three randomized controlled trials and 2 cohort studies were included in our study. In the 2 cohort studies, patients received Remdesivir for 10 days. 2 RCTs evaluated 10-day efficacy of treatment with Remdesivir versus placebo group and the other RCT compared its 5-day regimen versus 10-day regimen. Visual inspection of the forest plots revealed that the efficacy of Remdesivir was not much different in reducing 28-day mortality versus 14-day mortality rates. Besides, 10-day treatment regimen overpowered 5-day treatment and placebo in decreasing time to clinical improvement. All adverse event rates did not have a significant difference; however, severe adverse event rate was lower in the 5-day Remdesivir group compared to the 10-day and placebo groups. Conclusion: 5-day course of Remdesivir therapy in COVID-19 patients is probably efficacious and safe, and patients without invasive mechanical ventilation benefit the most. Treatment can be extended to 10 days if satisfactory improvement is not seen by day 5. Most benefits from Remdesivir therapy take place in the first 14 days of the start of the treatment.

Aim: Talimogene laherparepvec (T-VEC) is a genetically modified oncolytic herpesvirus approved for the treatment of unresectable, locoregionally advanced and recurrent melanoma. There is little relevant literature in the context of retreatment with T-VEC. Materials & methods: We reviewed four patients aged 71–87 years old with stage IIIB–IV melanoma at treatment who were rechallenged with T-VEC after experiencing recurrence of locoregional disease or prior treatment-limiting toxicity. Results: Cessation of initial treatment was due to one of the following reasons: severe adverse event (one case), mixed response (one case) or complete response (two cases). Three males and one female underwent T-VEC retreatment with a mean of 5.5 injection cycles. Three patients experienced a complete response to retreatment, while one experienced disease progression. Conclusion: Intralesional T-VEC may be effective and well-tolerated in patients who have completed prior T-VEC therapy.
