ABSTRACT
Introduction: Recent research has observed the ability of coronavirus disease 2019 (COVID-19) to spread in the brain from the respiratory system. The associated neurological disorder includes encephalopathies, inflammatory syndromes, stroke, peripheral neuropathies, and various other central nervous system disorders. This study aims to highlight the long-term neurological sequelae in patients with COVID-19 disease. Methods: This long-term study was carried out in the COVID-19 unit of a tertiary care hospital in Pakistan from July 2020 to July 2021. After obtaining informed consent, we enrolled 1000 patients who recovered from COVID-19 and were discharged. The participants were followed up after 30 and 90 days. Results: At the time of enrollment, there were 602 (60.2%) males and 398 (39.8%) females. The most common neurological symptom on 30-day follow-up was headache (8.8%), followed by insomnia. The most common neurological symptom on day 90 follow-up was insomnia (5.07%), followed by an altered sense of smell (3.3%). Conclusion: COVID-19 tends to produce a wide range of neurological symptoms, ranging from headache to anosmia to increased risk of stroke, that complicates clinical management. Potential neurologic effects and drug interactions have been reported secondary to the medications used to treat COVID-19. In light of the aforementioned facts, COVID-19 could potentially have a long-term effect on the brain. Therefore, it is important that the clinicians must be aware of the potential neurologic complications. Lastly, proper follow-up is recommended that would aid in timely recognition and management of the neurological disorder.
ABSTRACT
INTRODUCTION: The symptoms of coronavirus disease-19 (COVID-19) may range from mild to severe. Patients usually present with fever, cough, and other respiratory tract symptoms, but may also be asymptomatic. Some studies have also indicated the ocular involvement by the virus. This study aims to look deeply into all ophthalmic findings seen in COVID-19 patients and their clinical characteristics. METHODS: This longitudinal study was conducted in the COVID-19 unit of a tertiary care hospital, Pakistan. Data of patients hospitalized with COVID-19 infection between July 2020 and March 2021 were included in the study. Ophthalmological examination was done at the time of admission and was repeated every alternate day to look for any ophthalmological manifestation. RESULTS: Out of 441 (n= 441), 61 (13.8%) participants had ophthalmological findings on examination. Patients with ophthalmological findings were significantly younger compared to patients without ophthalmological findings (42 ± 6 years vs. 44 ± 7; p-value, 0.03). C-reactive protein (CRP) was also significantly higher in patients with ophthalmological findings (122.2 ± 16.2 vs. 112.8 ± 19.8; p-value, 0.005). The most common ophthalmological finding was conjunctival irritation (50.8%), followed by diplopia (27.8%) and cotton wool spots (27.8%). CONCLUSION: Ophthalmological findings are prevalent in patients with COVID-19. In this study, patients with higher CRP levels were associated with ophthalmological findings. It is important to conduct ophthalmological examinations in patients with COVID-19, as they may give a clue about other complications associated with COVID-19.
