Acute Pyelonephritis I: Introduction

Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...

Necrotizing fasciitis (NF) incidence varies geographically in Manitoba, with higher rates observed in Burntwood RHA and among the Aboriginal population. Patient outcomes for this severe infection were consistent across all regions.

Area of Science:

  • Infectious Diseases
  • Epidemiology
  • Public Health

Background:

  • Necrotizing fasciitis (NF) is a severe, rapidly progressing infection with significant morbidity and mortality.
  • Group A beta-hemolytic Streptococcus is a common causative agent, but diagnosis and treatment remain challenging.
  • Understanding geographic variations in NF incidence is crucial for targeted public health interventions.

Purpose of the Study:

  • To investigate the incidence and geographic distribution of necrotizing fasciitis (NF) in Manitoba.
  • To identify potential variations in NF incidence and patient outcomes across different Regional Health Authorities (RHAs).
  • To explore the impact of ethnicity on NF incidence and outcomes within the province.

Main Methods:

  • A 6-year retrospective chart review (2004-2009) of 130 patients with NF admitted to the Health Sciences Center.

Related Experiment Videos

  • Analysis of patient demographics, comorbidities, causative organisms, infection location, and treatment outcomes.
  • Statistical comparison of NF incidence and outcomes based on RHA and ethnicity.

    • Main Results:

    • The overall mortality rate for NF was 13.1%, with advanced age identified as an independent risk factor.
    • Lower extremity infections were most common (44.6%), and Group A beta-hemolytic Streptococcus was the primary pathogen (63.9%).
    • While patient outcomes (length of stay, amputation rates, mortality) did not differ by RHA, NF incidence varied significantly, notably higher in Burntwood RHA and among the Aboriginal population.

    Conclusions:

    • Necrotizing fasciitis incidence in Manitoba shows significant geographic and ethnic disparities, particularly in Burntwood RHA and the Aboriginal population.
    • Despite variations in incidence, patient prognosis for NF appears equivalent across different RHAs.
    • These findings highlight the need for localized public health strategies to address disparities in NF.
