Pseudouremic pruritus: a scabies epidemic in a dialysis unit
Summary
A scabies epidemic in a hospital dialysis unit was initially misdiagnosed as uremic pruritus. Prompt treatment with lindane lotion successfully eradicated the scabies outbreak among patients and staff.
Area of Science:
- Infectious Diseases
- Dermatology
- Nephrology
Background:
- Scabies outbreaks can occur in healthcare settings.
- Dialysis patients are susceptible to various complications, including pruritus.
Observation:
- A scabies epidemic occurred in a university hospital dialysis unit.
- Itching in patients was initially misattributed to uremic pruritus, delaying diagnosis.
- Cases among healthcare staff confirmed the scabies outbreak.
Findings:
- Sixteen cases of scabies were identified (7 patients, 9 staff).
- 1% lindane lotion applied to all patients and staff eradicated the epidemic.
- This represents the first reported case of a dialysis unit-associated nosocomial scabies epidemic.
Implications:
- Nosocomial scabies outbreaks in dialysis units are possible and can mimic uremic pruritus.
- Early recognition and prompt, comprehensive treatment are crucial for controlling such outbreaks.
- This highlights the importance of considering scabies in dialysis patients presenting with unexplained pruritus.
