superinfection

 [soo″per-in-fek´shun]
a new infection occurring in a patient having a preexisting infection; for example, bacterial infection may occur in patients with viral respiratory disease, or a chronic hepatitis B carrier may become infected with hepatitis D virus. Superinfection can complicate the course of antimicrobial therapy when the organisms causing the new infection are resistant to the drugs being used to treat the first infection.

However, considering the fact that the majority of patients assessed had been infected with HCV more than two decades in the past, and previous studies have demonstrated significantly higher seroprevalence of HEV-3 after 50 years of age, we can infer a higher probability of HEV superinfection at some point during chronic HCV infection; (2) multivariate analysis showed a substantial loss of statistical power for detecting possible associations due to incomplete data; (3) in the alternative multiple logistic regression model for cirrhosis (Table 4), age was also tested as continuous variable and the result was a p-value of 0.106 for HEV.
It is notable that the increased level of IL-10 was remarkable compared with that of IL-1[beta], suggesting that cytokines induced by the influenza virus play an important role in the immunological mechanisms underlying influenza virus-GAS superinfection.
While it is important to consider the possibility that HSV colitis was in fact a triggering condition rather than merely a superinfection, we consider this to be less likely in our presented case.
They are derived from HIV and do not express the EIAV SU protein responsible for preventing EIAV superinfection. Superinfection is also prevented in HIV infections, as a result of the Nef and Vpu proteins (Lindwasser et al.
Importantly, 90% of our patients with invasive fungal infections had a documented postoperative leak as well as a higher frequency of intra-abdominal abscesses and pleural effusions than those without fungal superinfection.
Empiric broad-spectrum antibiotics and aggressive hemodynamic support, followed by proper surgical intervention when warranted, are critical when bacterial superinfection is suspected as a delay may result in poorer outcomes [5].
The clinical features depend on the affected organs but are usually related to compression symptoms; besides these, there are many potential complications, namely, local complications (superinfection and rupture) or secondary involvement of other organs due to hematogenous dissemination.
Xeroform dressing with an antibiotic ointment can be used to prevent a superinfection and allow wound healing.
(1) Such aneurysms may result from bacteremia and embolization of infectious material, which cause superinfection of a diseased and roughened atherosclerotic surface.
He treated many children with measles, and as he had been taught in the best biomedical model in his medical school, he did not routinely prescribe antibiotics unless he found evidence of superinfection. Regrettably, Chalmers' patients had significantly higher mortality compared to the children being taken care of by his Palestinian colleague, who, on the other hand, prescribed antibiotics to every child with measles.
