Challenges in the Management of Gram-Negative Bacterial Infections in Patients With Ventriculoperitoneal Shunt

Abstract: Gram-negative bacterial infections of the central nervous system (CNS) have worse clinical outcomes. The most common bacteria include Escherichia Coli , Citrobacter species, Enterobacter species, Serratia species, and Pseudomonas aeruginosa . There are multiple risk factors for CNS infection after shunt insertion, including younger age, obstructive hydrocephalus, shunt revision surgery, and trauma. The clinical presentation of a ventriculoperitoneal (VP) shunt infe… Show more

“…As discussed previously, the detection of S. epidermidis is not surprising given its ubiquitous nature on human skin, but whether it is a true pathogen or a contaminant in this case is unclear [10,[26][27][28][29]. The other pathogens identified by WGAS included E. coli, K. variicola, and P. tolaasii-none of these pathogens had been found on STGG culture, though the former two are known to be pathogenic and could potentially cause CNS infection [36][37][38][39][40]. WGAS has a known sensitivity profile and is able to detect even small amounts of microbial genetic material-therefore, whether the WGAS findings were more accurate or potentially due to amplification of contaminant DNA cannot be known [17].…”

“…Alguns fatores de risco associados à formação de pseudocistos incluem histórico prévio de infecções, múltiplas revisões do sistema de derivação ventriculoperitoneal e intervenções cirúrgicas abdominais anteriores. Ahmad et al, (2021), por sua vez, explana sobre as infecções bacterianas Gramnegativas como uma grave complicação da DVP. É afirmado que a frequência dessas infecções é mais alta nos primeiros dias após a inserção do shunt, com taxas variando amplamente de 56% a 87% dentro do primeiro mês.…”

“…Além disso, certas condições subjacentes, como hidrocefalia congênita e disrafismo espinhal, estão particularmente associadas a taxas mais altas de infecção. Por exemplo, a hidrocefalia obstrutiva tem uma taxa de infecção mais elevada do que outros tipos de hidrocefalia, como a comunicante ou idiopática (Ahmad et al, 2021).…”

“…En otros grupos etarios encontramos otros factores predisponentes para meningitis por BGN, como el uso de dispositivos intraventriculares y las intervenciones quirúrgicas en SNC 6 . En estos casos, la etiología fue más variada y se encontraron gérmenes relacionados al entorno hospitalario, como enterobacterias diferentes a E. coli y BGN no fermentadores como Pseudomonas spp 8,[21][22][23][24][25][26] . Estos microorganismos se han relacionado con colonización durante intervenciones quirúrgicas, capacidad de formar biopelícula en dispositivos invasivos y estancia hospitalaria prolongada 27 .…”
