Background: Immunocompromised patients receiving B-cell-depleting therapies are at increased risk of persistent SARS-CoV-2 infection, with many experiencing fatal outcomes. We report a successful outcome in a patient with rheumatoid arthritis (RA) on rituximab diagnosed with COVID-19 in July 2020 with persistent infection for over 245 days.
Results: The patient received numerous treatment courses for persistent COVID-19 infection, including remdesivir, baricitinib, immunoglobulin and high doses of corticosteroids followed by a prolonged taper due to persistent respiratory symptoms and cryptogenic organizing pneumonia. Her clinical course was complicated by sinusitis with secondary bacteremia, and cytomegalovirus (CMV) viremia and pneumonitis. SARS-CoV-2 positive RNA samples were extracted from two nasopharyngeal swabs and sequenced using targeted amplicon Next-Generation Sequencing which were analyzed for virus evolution over time. Viral sequencing indicated lineage B.1.585.3 SARS-CoV-2 accumulated Spike protein mutations associated with immune evasion and resistance to therapeutics. Upon slowly decreasing the patient's steroids, she had resolution of her symptoms and had a negative nasopharyngeal SARS-CoV-2 PCR and serum CMV PCR in March 2021.
Conclusion: A patient with RA on B-cell depleting therapy developed persistent SARS-CoV-2 infection allowing for virus evolution and had numerous complications, including viral and bacterial co-infections with opportunistic pathogens. Despite intra-host evolution with a more immune evasive SARS-CoV-2 lineage, it was cleared after 245 days with reconstitution of the patient's immune system.

Background: Tavaborole (TAV), a benzoxaborole derivative, is an FDA-approved antifungal agent for treating onychomycosis, a common and persistent fungal infection of the toenails.
Objective: This study aimed to develop a robust stability-indicating HPTLC method to determine TAV in nanostructured lipid carriers (NLC) using a comprehensive approach that includes risk assessment, and Analytical Quality by Design.
Methods: The critical method parameters influencing the HPTLC results were screened using a Placket-Burman screening design followed by its optimization using a central composite optimization design.

Background: The infectious hypothesis of Alzheimer's disease (AD) suggests that microbes may play a role in pathogenesis by triggering the pathologic cascade or contributing to disease progression. Herpesviruses, such as Epstein-Barr virus (EBV), have been of high interest in AD and related neurodegenerative diseases, in part due to their ability to establish lifelong latent infection and potentially reactivate. However, further research is needed to fully understand the role of herpesviruses in these diseases.

Osteopetrosis is a rare systemic skeletal disorder characterized by increased bone density and mass resulting from suboptimal or impaired resorption of osteoclastic bone. Compromised bone marrow function and associated disorders of red blood cells contribute to hematopoietic abnormalities, which exacerbate the risk of complex, recurrent infections such as jaw osteomyelitis. This case report describes the treatment of a 68-year-old Korean female with autosomal-dominant osteopetrosis who presented with severe and persistent jaw osteomyelitis complicated by hematopoietic dysregulation.

Background: African Americans (AA) are disproportionately affected by Long COVID, highlighting the need for targeted research to understand the enduring consequences of COVID-19 within this community. Among the array of symptoms associated with post-acute sequelae of SARS-CoV-2 (PASC), cognitive impairments emerge as a significant concern affecting up to 19% of COVID survivors. In this study, our goal is to comprehensively characterize the specific cognitive domains impacted in older AA adults.

Background: Many common symptoms in post-acute sequelae following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection (PASC) overlap with those of multiple sclerosis (MS). We examined symptoms and performance of the PASC score, developed in the general population, in MS based on infection history.
Methods: We surveyed North American Research Committee on Multiple Sclerosis (NARCOMS) registry participants regarding infections and categorized participants based on infection history.
