Background:
Erysipelas is a common bacterial infection of the skin and subcutaneous tissue. In certain patients, the triggering factor can be identified, but in many cases, it remains elusive. Prior research indicates that pre-existing subclinical lymphedema in patients might serve as a triggering factor for the development of erysipelas.
Objectives:
We investigated the prevalence of subclinical lymphedema on the unaffected leg in patients with a recent history of erysipelas by performing lymphoscintigraphy of both legs.
Methods:
In a prospective study, 106 consecutive patients (mean age 53.4 years; 87/19: men/women) 3 to 6 months after erysipelas episode were included in the study. In all patients, lymphoscintigraphy was performed by subcutaneous injection of Tc-99m-labelled human albumin into both feet according to standard protocol.
Results:
Subclinical lymphedema on the unaffected leg was found in 82% of patients, with a similar prevalence in all genders and age groups, and in patients with or without erysipelas risk factors. Moreover, the prevalence of subclinical lymphedema increased proportionally with the number of erysipelas episodes: among those with a single episode, 74% exhibited subclinical lymphedema, whereas among those with 3 or more episodes, the prevalence was 100%.
Conclusions:
We found a high prevalence of subclinical lymphedema in the unaffected leg in erysipelas patients, indicating its frequent bilateral occurrence and its role as a primary trigger of erysipelas. Moreover, our study highlights subclinical lymphedema as a risk factor for erysipelas recurrences. Thus, our clinical recommendation suggests bilateral leg compression therapy in erysipelas patients to prevent recurrence and lymphedema exacerbation.
Insights
Subclinical lymphedema is common in patients with erysipelas, often occurring bilaterally. This condition frequently triggers erysipelas and increases recurrence risk, suggesting compression therapy for prevention.
Area of Science:
- Dermatology
- Infectious Diseases
- Vascular Medicine
Background:
- Erysipelas is a common bacterial skin infection with often unknown triggers.
- Pre-existing subclinical lymphedema is suspected as a potential trigger for erysipelas.
- Understanding triggers is crucial for managing recurrent infections.
Purpose of the Study:
- To determine the prevalence of subclinical lymphedema in the unaffected leg of erysipelas patients.
- To investigate the relationship between subclinical lymphedema and erysipelas episodes.
- To assess the potential role of subclinical lymphedema as a primary trigger and risk factor for erysipelas.
Main Methods:
- Prospective study of 106 consecutive patients 3-6 months post-erysipelas.
- Lymphoscintigraphy performed on both legs using Tc-99m-labelled human albumin.
- Analysis of subclinical lymphedema prevalence across demographics and risk factors.
Main Results:
- Subclinical lymphedema found in 82% of patients on the unaffected leg.
- Prevalence was consistent across genders, age groups, and erysipelas risk factors.
- Lymphedema prevalence increased with erysipelas episodes (74% for one, 100% for three+).
Conclusions:
- High prevalence of bilateral subclinical lymphedema in erysipelas patients.
- Subclinical lymphedema frequently triggers erysipelas and increases recurrence risk.
- Recommends bilateral leg compression therapy to prevent erysipelas recurrence and lymphedema exacerbation.

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
