Distinguishing cytomegalovirus meningoencephalitis from other viral central nervous system infections.

BACKGROUND: Hallmarks of cytomegalovirus (CMV) meningoencephalitis include fever, altered mental status, or meningismus with pleocytosis, elevated protein and hypoglycorrhachia on cerebrospinal fluid (CSF) analysis. Magnetic resonance imaging may show ventriculitis, ependymitis or periventricular enhancement. Studies are limited comparing clinical and laboratory characteristics to other viral etiologies. OBJECTIVES: This multi-center, retrospective cohort analysis reviewed patients with CMV meningitis or encephalitis and compared clinical features, laboratory findings and outcomes to the most common viral causes of meningoencephalitis. STUDY DESIGN: Patients with encephalitis or aseptic meningitis and detectable genetic material by polymerase chain reaction were identified. Clinical characteristics, laboratory findings and neuroimaging were collected from the electronic medical record. Data analysis was performed comparing CMV to other viral etiologies. RESULTS: 485 patients were evaluated and included cases of CMV (n = 36) which were compared with herpes simplex virus (n = 114), enterovirus (n = 207), varicella zoster virus (n = 41) and West Nile virus (n = 81). Human immunodeficiency virus (HIV) infection was seen more frequently in CMV infection compared with all other viral etiologies. Clinical presentations and CSF findings of other viral etiologies differ compared with CMV. Hypoglycorrhacia occurred more often with CMV compared with other viral pathogens. Outcomes were significantly worse compared with enterovirus, herpes simplex virus and varicella zoster virus but not West Nile virus. CONCLUSIONS: CMV meningoencephalitis occurs most often in patients with HIV and encephalitis occurs more frequently than meningitis. Clinical and laboratory findings differ compared with other viral etiologies and can support consideration of CMV in the differential diagnosis of patients with meningoencephalitis.

Pretransplant dialysis modality and long-term patient and kidney allograft outcome: a 15-year retrospective single-centre cohort study.

Among factors determining long-term kidney allograft outcome, pretransplant renal replacement therapy (RRT) is the most easily modifiable. Previous studies analysing RRT modality impact on patient and graft survival are conflicting. Studies on allograft function are scarce, lack sufficient size and follow-up. We retrospectively studied patient and allograft survival together with allograft function and its decline in 2277 allograft recipients during 2000-2014. Pretransplant RRT modality ≥60 days as grouped into "no RRT" (n = 136), "haemodialysis (HD)" (n = 1847), "peritoneal dialysis (PD)" (n = 159), and "HD + PD" (n = 135) was evaluated. Kaplan-Meier analysis demonstrated superior 5-/10-/15-year patient (93.0/81.8/73.1% vs. 86.2/71.6/49.8%), death-censored graft (90.8/85.4/71.5% vs. 84.4/75.2/63.2%), and 1-year rejection-free graft survival (73.8% vs. 63.8%) in PD versus HD patients. Adjusted Cox regression revealed 34.5% [1.5-56.5%] lower hazards of death, whereas death-censored graft loss was similar [HR = 0.707 (0.469-1.064)], and rejection was less frequent [HR = 0.700 (0.508-0.965)]. Allografts showed higher 1-/3-/5-year estimated glomerular filtration rate (eGFR) in "PD" versus "HD" groups. Living donation benefit for allograft function was most pronounced in groups "no RRT" and "PD". Functional allograft decline (eGFR slope) was lowest for "PD". Allograft recipients on pretransplant PD versus HD demonstrated superior all-cause patient and rejection-free graft survival along with better allograft function (eGFR).

Contribution of the BioFire® FilmArray® Meningitis/Encephalitis Panel: Assessing Antimicrobial Duration and Length of Stay.

INTRODUCTION: Traditional evaluation of meningitis includes cerebrospinal fluid (CSF) culture and gram stain to pinpoint specific causal organisms. The BioFire® FilmArray® Meningitis/Encephalitis (ME) Panel has been implemented as a more timely evaluation method. This study sought to assess if the BioFire® ME Panel was associated with a decreased length of stay or decreased antimicrobial duration when used in the diagnosis of meningitis or encephalitis. METHODS: A case, historical-control, chart review was performed on patients admitted to a regional medical center with CSF pleocytosis during Cohort 1 (the year prior to BioFire® ME Panel implementation) and Cohort 2 (the year after BioFire® ME Panel implementation). Length of hospital stay, duration of antimicrobials, and BioFire® ME Panel result were gathered and analyzed. RESULTS: Average length of stay for both cohorts was about four hospital days. Approximately three-fourths of all patients received antibiotic/antiviral treatment with an average of three days duration. No significant differences were observed between groups. The mean (median) duration of antimicrobials in the year prior to and after the BioFire® ME Panel implementation was 3.6 (3) and 3.1 (2) days, respectively (p = 0.835). The mean (median) length of stay in the year prior to and after the BioFire® ME Panel implementation was 5.8 (4) and 5.4 (4) days, respectively (p = 0.941). Among the patients admitted after the implementation of the BioFire® ME Panel, 4.3 % (n = 2) had a positive bacterial result, 38.3% (n = 18) had a positive viral result, and 57.4% (n = 27) had a negative result. Of the 27 negative results, 77.8% (n = 21) were treated with antimicrobial medication. CONCLUSIONS: This study suggested there is no difference between length of stay or antimicrobial duration in presumed meningitis cases assessed with traditional methods as compared to the BioFire® ME Panel.

HIV Care in Asian and Pacific Islanders in Kansas.

A complex cultural dynamic within the Asian and Pacific Islander (APIs) population contributes to barriers in HIV care. This qualitative narrative study investigated how awareness, resource accessibility, and cultural taboo impact HIV care in APIs in Kansas. Eleven HIV-infected API patients were interviewed. Two evaluators independently completed a qualitative themes analysis. Important themes impacting HIV care included lack of awareness, sex as a taboo topic, and misconceptions about HIV infection. These factors create a closed community regarding HIV prevention and care. Clinicians must be aware of these barriers and provide specific culturally sensitive information and care to this population.
