Insights

Staphylococcus aureus nasal carriage is more common in patients on long-term hemodialysis (HD). Antibiotic resistance rates are significantly higher in these HD patients compared to the control group.

Area of Science:

  • Infectious Diseases
  • Nephrology
  • Microbiology

Background:

  • Staphylococcus aureus is a leading cause of serious infections in patients undergoing long-term hemodialysis (HD).
  • Methicillin-resistant S. aureus (MRSA) strains are increasingly multidrug-resistant, posing treatment challenges.
  • Understanding S. aureus prevalence and resistance patterns in HD patients is crucial for effective antimicrobial therapy.

Purpose of the Study:

  • To determine the frequency of S. aureus nasal carriage in diabetic and non-diabetic HD patients.
  • To investigate the antimicrobial resistance patterns of S. aureus strains isolated from HD patients.
  • To assess the correlation between HD duration, diabetes mellitus, and S. aureus carriage.

Main Methods:

  • A cross-sectional study involving 261 HD patients and 160 control individuals in Hatay.
  • Screening for S. aureus nasal carriage and assessment of antimicrobial susceptibility profiles.
  • Statistical analysis to identify correlations with HD duration, diabetes mellitus, age, and sex.

Main Results:

  • S. aureus positivity was significantly higher in HD patients (56.7%) compared to controls (16.2%).
  • Longer duration of HD was significantly correlated with S. aureus isolation.
  • Antibiotic resistance rates were significantly higher in S. aureus strains from HD patients than controls.

Conclusions:

  • Nasal carriage of S. aureus is more prevalent in HD patients, with longer HD duration being a risk factor.
  • Diabetes mellitus, age, and sex were not found to be risk factors for S. aureus nasal carriage.
  • HD patients exhibit higher rates of antibiotic resistance in S. aureus, necessitating careful treatment strategies.

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.
