Summary
Giant cell arteritis (GCA), an inflammatory condition, may be triggered by COVID-19 infection. Early diagnosis and treatment with prednisone can prevent vision loss and resolve symptoms.
Area of Science:
- Rheumatology
- Infectious Diseases
- Ophthalmology
Background:
- Giant cell arteritis (GCA) is a systemic vasculitis affecting large arteries.
- A known complication of GCA is irreversible vision loss.
- The link between viral infections and GCA is established, but the specific relationship with COVID-19 requires further study.
Observation:
- An elderly male patient with a recent COVID-19 diagnosis presented with sudden vision loss, headache, and jaw claudication.
- Ophthalmological examination suggested GCA.
- A temporal artery biopsy confirmed the GCA diagnosis.
Findings:
- The patient's vision stabilized, and systemic symptoms resolved after treatment with prednisone.
- This case highlights a potential temporal association between COVID-19 infection and the onset of GCA.
Implications:
- The findings support the hypothesis that viral infections, including COVID-19, may act as an infectious trigger for GCA.
- Further research is warranted to elucidate the mechanisms and clinical significance of this potential link.
- This case underscores the importance of considering GCA in patients with relevant symptoms following COVID-19 infection.

01:11Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

01:22Pericarditis I: Introduction
Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
01:25Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
01:27Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
01:25Acute Inflammation II: Local and Systemic Effects
Acute inflammation produces a coordinated set of local and systemic changes that limit injury, eliminate pathogens, and initiate repair. These responses arise within minutes of infection, trauma, or chemical insult and are driven by vascular alterations and leukocyte-derived mediators. When the stimulus resolves, the reaction typically abates within days.Local EffectsAt the site of injury, arteriolar vasodilation increases blood flow, resulting in redness and warmth. Simultaneously, increased...
01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
