Invasive Pneumococcal Disease and COVID-19 With Acute Otitis Media and a Tegmen Tympani Defect.

is a leading cause of otitis media, pneumonia, sinusitis, and meningitis. This encapsulated, gram-positive bacterium colonizes the nasopharynx. Major risk factors, including age, hyposplenism, and immunosuppression, predispose to serious infections. Viral infections are known to increase the risk of secondary bacterial infections as the initial immune response can compromise defenses against bacteria. Coronavirus disease 2019 (COVID-19) similarly poses a risk for secondary bacterial infections and coinfections, such as invasive pneumococcal disease (IPD). Still, temporal relationships between IPD and COVID-19 are not fully understood. IPD may also be a complication of untreated acute otitis media. COVID-19 and pneumococcal bacteremia, a form of IPD, have both been shown to damage the blood-brain barrier and gain access to the central nervous system, resulting in deep infections, namely, meningitis and encephalitis. Presented here is the case of a 70-year-old female partially vaccinated against pneumococcal disease, who was initially evaluated for an elevated temperature, acute encephalopathy, and COVID-19. Further investigation confirmed IPD in the form of bacteremia and meningitis. The patient had a protracted disease course complicated by sick sinus syndrome and altered mental status, which led to the identification of otitis media and a right tegmen tympani defect. Emergent implantation of a single-chamber temporary pacemaker and myringotomy with tube placement was performed. Lumbar puncture showed evidence of meningitis. Antibiotic therapy eventually narrowed to ceftriaxone and continued for a total of six weeks. The presence of comorbidities, history of incomplete pneumococcal vaccination series, and concomitant infection with COVID-19 may explain the development of IPD and other complications seen in this case. Furthermore, tegmen tympani defects and damage to the blood-brain barrier can serve as a route for otogenic intracranial sepsis and meningitis. This case serves to reinforce the importance of pneumococcal vaccination and the high clinical suspicion necessary for the prompt diagnosis and treatment of IPD. However, despite vaccination, IPD remains a life-threatening disease due to poor antibiotic penetration in the central nervous system and overlapping presentations with coinfections, such as COVID-19.
