Management of Infections in Patients with Renal Impairment

Patient Assessment and Monitoring

The American Journal of Kidney Diseases recommends that patients with impaired renal function (GFR 30 ml/min) and ileum conduit should be monitored closely, with careful attention to fluid management and vital sign monitoring, particularly in the presence of hypotension (RR 90/60) and fever (38.5°C) 1
The American family physician suggests that patients with renal impairment are at higher risk for acute kidney injury when using NSAIDs, which should be avoided in this population 2

The Annals of Internal Medicine recommends that many medications require dose reduction in patients with impaired renal function (GFR 30 ml/min), including Novaminsulfon, which should be reduced by 50-66% to 500 mg 1-0-1 instead of 2-2-2 4
Paracetamol may be used as an alternative to Novaminsulfon, with a maximum dose of 3g/day, in patients with impaired renal function 1

Empirical antibiotic therapy should be initiated in patients with suspected bacterial infection, with dose adjustment according to renal function, and avoidance of nephrotoxic antibiotics 2
Nitrofurantoin is contraindicated in patients with GFR <30 ml/min, according to the American family physician 3

Patients with persistent hypotension despite fluid administration, worsening renal function, signs of systemic infection, or inadequate response to outpatient therapy within 24-48 hours should be admitted to the hospital for further management 1
