Antibiotic Prophylaxis in Chronic Renal Failure Hemodialysis Gregory A. Chambers, PA-S Lock Haven University February 25, 2009

Causes of End-Stage Renal Disease: Diabetic Nephropathy Hypertension Glomerulonephritis HIV Nephropathy Renal Artery Stenosis Polycystic Kidney Disease Others

The first three causes account for nearly 75% of all end stage renal disease! Diabetic Nephropathy (25-40%) Hypertension Glomerulonephritis

Diabetic Nephropathy Leading Cause: Obesity (AKA: Hypernutrition)

Obesity in the United States Percent of Obese (BMI > 30) in U.S. Adults play stop

Obesity in the United States (BMI > 30) 1997 – 19.4% of adults 2004 – 24.5% of adults 2007 – 26.6% of adults

As a Result: End-stage renal disease will increase dramatically in the next several years as a result of the deconditioning of America!

Hemodialysis:

Outpatient procedure Attach catheter to Hemodialysis equipment Blood passes through chambers with semi-permeable membranes Dialysis solutions on opposite side of membranes Simple diffusion – toxins, excess water out – electrolytes and nutrients in Anticoagulation achieved with heparin

What is Missing

Antibiotic Therapy

Hemodialysis Complications: Hypotension - frequent Fatigue - frequent Nausea - frequent Headache - frequent Sepsis – 1-2 % of all dialysis hours Endocarditis – small percent of sepsis cases Stroke – small percent of endocarditis cases

Let’s Do The Math……… Hemodialysis 3 times per week……… Total times per year (52 weeks X 3 times per week) 156 trips to the dialysis center……… Average time per dialysis session = 4 hours……… Annual time in dialysis = 624 hours……… Rate to infection = 1 – 2% Total infections per year = 6.2 – 12.4………

Research In all the sources used, prophylaxis use of either topical or intra-luminal antibiotics decreased the rates of infection by 0.22 – 0.46%.

Research While this may not see to be a significant amount, it would reduce the incidence of infection by nearly 25.0%!

Research: Antibiotics Tested: Gentamicin (aminoglycoside) Cefazolin (1 st generation cephalosporin) Cefotaxime (3 rd generation cephalosporin) Vancomycin (glycopeptide) Minocycline (tetracycline) Taurolidine (antimicrobial properties and stimulates leucocytes)

Futures Studies: Although the research showed significant rates of infection with antibiotic prophylaxis, the study sizes were very small (n=70 – 6) and were mostly conducted outside the United States.

Future Studies: In addition, many of the studies revealed bias in either the design of the study or in the interpretation of the results.

Future Studies: A large cohort, double blinded, randomized study conducted in the United States is needed to truly identify the efficacy of antibiotic prophylaxis in hemodialysis patients.
