Insights

Recurrent Rhodotorula rubra fungemia, a rare yeast infection, occurred in a patient with short bowel syndrome and juvenile rheumatoid arthritis. Chronic skin colonization likely caused the repeated catheter-associated bloodstream infections.

Area of Science:

  • Medical Mycology
  • Infectious Diseases
  • Clinical Microbiology

Background:

  • Parenteral nutrition and immunosuppressive therapy increase risks for opportunistic infections.
  • Catheter-associated bloodstream infections are a significant concern in patients requiring long-term central venous access.
  • Rhodotorula rubra is an emerging fungal pathogen, particularly in immunocompromised individuals.

Observation:

  • A 34-year-old male with short bowel syndrome and juvenile rheumatoid arthritis experienced recurrent fungemia.
  • The patient received chronic parenteral nutrition and intermittent immunosuppressive agents.
  • Recurrent infections were caused by Rhodotorula rubra, a type of yeast.

Findings:

  • The patient developed catheter-associated Rhodotorula rubra fungemia over a one-year period.
  • Infection was linked to the use of central venous catheters.
  • Chronic skin colonization by Rhodotorula rubra was presumed to be the cause of recurrent infections.

Implications:

  • This case highlights the potential for chronic skin colonization to lead to recurrent fungemia in susceptible patients.
  • Understanding the pathogenesis of Rhodotorula rubra infections is crucial for effective management.
  • Preventive strategies targeting skin colonization may be necessary for patients at high risk.

Urinary Tract Infection II: Pathophysiology

The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
Trichomoniasis01:18

Trichomoniasis

Trichomonas vaginalis is a flagellated protozoan parasite and the causative agent of trichomoniasis, one of the most prevalent non-viral sexually transmitted infections in the United States. This extracellular parasite primarily colonizes the lower genitourinary tract in women—particularly the vagina—and in men, the urethra and prostate. Its structural and functional adaptations enable its survival, motility, and pathogenicity within the host environment.Structural Features and Host EntryT.
Candidiasis01:20

Candidiasis

Candidiasis is a fungal infection caused by opportunistic species of Candida. It can affect various anatomical sites, including the skin, oral cavity, nails, and genitourinary tract. Among its forms, vaginal candidiasis is the most common type of mucosal infection. It typically results from the overgrowth of Candida albicans in the vaginal mucosa. Under normal conditions, C. albicans exists as a commensal organism within the vaginal microbiota, regulated by the dominance of lactobacilli, which...

Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care

A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...

Urinary Tract Infection I: Introduction

Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

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,...
