Early clinical observations in prospectively followed patients with fungal meningitis related to contaminated epidural steroid injections.

UNLABELLED: Chinese translation BACKGROUND: Administration of epidural steroid injections (ESIs) with contaminated methylprednisolone resulted in an outbreak of fungal meningitis in many locations in the United States. OBJECTIVE: To characterize early clinical findings and initial response to treatment. DESIGN: Case series with standardized observation studied from 4 October to 31 October 2012. SETTING: An 800-bed hospital in Virginia. PATIENTS: 172 patients who presented to the hospital with exposure to contaminated ESI. INTERVENTION: Standardized approach to screening, case definition, treatment, and data collection. MEASUREMENTS: Clinical findings, cerebrospinal fluid (CSF) values, magnetic resonance imaging (MRI), serum and CSF voriconazole concentrations, and clinician assessment of response to therapy. RESULTS: Of 172 patients presenting to the hospital who had had ESI, 131 had lumbar puncture because of symptoms or signs consistent with central nervous system disease. Twenty-five (19%) had neutrophilic meningitis. All were started on voriconazole therapy alone. Three patients developed stroke during treatment. Ten patients had arachnoiditis, another had an epidural abscess, and 9 had urine retention. Fifteen continued to receive voriconazole, and 10 were switched to amphotericin B. Cerebrospinal fluid leukocyte counts began to decrease by day 13 of treatment. Findings on MRI included ventriculitis, leptomeningeal enhancement, infarction, hemorrhage, and arachnoiditis. Serum voriconazole levels varied, and CSF concentrations of voriconazole were approximately 50% those of serum. Exserohilum rostratum and Cladosporium species have been cultured. LIMITATIONS: This is an observational study of an evolving outbreak. Not all exposed patients presented for evaluation. Follow-up is too short to determine final outcomes. CONCLUSION: Meningitis after receipt of contaminated ESI has been diagnosed in many exposed patients presenting to 1 hospital. Most patients have improved on receipt of empirical voriconazole therapy. The full natural history and long-term sequelae of this infection are currently unknown. PRIMARY FUNDING SOURCE: None.

Type 2 Diabetes Status, Diabetes Complication Severity Index Scores, and Their Relationship With COVID-19 Severity: A Retrospective Cohort Study of Hospitalized Patients in a Southwest Virginia Health System.

Background Studies have shown that patients with type 2 diabetes mellitus (T2DM) tend to have poorer outcomes associated with COVID-19, including increased rates of hospitalization, ICU admission, need for ventilatory support, and mortality. Methods We performed a retrospective cohort study that included all non-pregnant adult patients who were hospitalized as a result of COVID-19 in a Southwest Virginia health system between March 18, 2020, and August 31, 2022. T2DM status was treated as a binary variable. T2DM severity was assessed using the Diabetes Complications Severity Index (DCSI). Multivariate logistic regression was used to assess the relationship between T2DM status and COVID-19 severity outcomes. Multivariate logistic regression was also used to assess the relationship between DCSI score and COVID-19 severity outcomes among patients with an established diagnosis of T2DM at the time of COVID-19 hospital admission. Results Patients with T2DM had 1.27 times the odds of experiencing a poor COVID-19 clinical outcome (95% CI: 1.13, 1.43) and 1.35 times the odds of in-hospital mortality (95% CI: 1.14, 1.59) compared to patients without diabetes. Among patients with T2DM, increasing DCSI score was significantly associated with increased odds of experiencing a poor COVID-19 clinical outcome and in-hospital mortality. Conclusions Diabetic patients in our sample were at increased odds of experiencing poor COVID-19 clinical outcomes and in-hospital mortality compared to individuals without diabetes. Amongst patients with T2DM, increasing DCSI score was associated with worse COVID-19 outcomes. Clinical decision support tools may be able to utilize DCSI scores as an indicator of COVID-19 severity risk to facilitate decisions regarding treatment aggressiveness and resource allocation.

Update in Human Immunodeficiency Virus and Aging.

Effective and consistent antiretroviral therapy has enabled people with human immunodeficiency virus (HIV) (PWH) to survive longer than previously encountered earlier in the epidemic. Consequently, PWH are subject to the struggles and clinical conditions typically associated with aging. However, the aging process in PWH is not the same as for those who do not have HIV. There is a complex interplay of molecular, microbiologic, and pharmacologic factors that leads to accelerated aging in PWH; this leads to increased risk for certain age-related comorbidities requiring greater vigilance and interventions in routine care.

Braden score may be associated with time to onset of catheter-associated urinary tract infection in high-risk patients: Lessons learned from a root cause analysis tool.

Timely removal of the urinary catheter is an important strategy for decreasing catheter-associated urinary tract infections (CAUTIs). Data were aggregated from an electronic root cause analysis tool, which is used to collect and guide discussions on patient factors following a CAUTI event at our facility. This identified the Braden Scale score as a possible important predictor of early-onset CAUTI in high-risk patients and could potentially be leveraged for early action in urinary catheter removal.

Tuberculous Enteritis Presenting as Acute Appendicitis and Perirectal Abscess.

Mycobacterium tuberculosis has a wide variety of presentations. A rare occurrence is gastrointestinal tuberculosis. It may occur anywhere along the alimentary canal but usually occurs in the ileocecum with rare involvement of the appendix.

Tn2008-driven carbapenem resistance in Acinetobacter baumannii isolates from a period of increased incidence of infections in a Southwest Virginia hospital (USA).

OBJECTIVES: The objectives of this study were (i) to determine the genetic basis for carbapenem resistance in multidrug-resistant (MDR) Acinetobacter baumannii strains isolated from patients affected by a sudden increase in the incidence of infections by such organisms in a tertiary care hospital in Virginia, USA, in 2009-2010 and (ii) to examine whether such strains are commonly encountered in the hospital setting. METHODS: The whole genomes of one outbreak strain as well as one carbapenem-resistant and one carbapenem-sensitive strain from sporadic infections in 2010-2012 were sequenced and analysed. Then, 5 outbreak isolates and 57 sporadic isolates (of which 39 were carbapenem-resistant) were screened by PCR for relevant DNA elements identified in the genomics investigation. RESULTS: All three strains for which whole-genome sequences were obtained carried resistance genes linked to MDR phenotypes and a ca. 111-kbp plasmid (pCMCVTAb1) without drug resistance genes. Of these, the two carbapenem-resistant strains possessed a ca. 74-kbp plasmid (pCMCVTAb2) carrying a Tn2008 transposon that provides high-level carbapenem resistance. PCR analysis showed that all of the outbreak isolates carried both plasmids and Tn2008, and of the sporadic isolates 88% carried pCMCVTAb1, 25% contained pCMCVTAb2 and 50% of the latter group carried Tn2008. CONCLUSIONS: Carbapenem resistance in outbreak strains and 12% of sporadic isolates was due to the pCMCVTAb2-borne Tn2008. This is the first report of a Tn2008-driven outbreak of carbapenem-resistant A. baumannii infections in the Commonwealth of Virginia, which followed similar cases in Pennsylvania and Ohio.
