Burden, risk factors, and infectious complications of cellulitis and erysipelas in US adults and children in the emergency department setting.

BACKGROUND: Little is known about the use and burden of emergency department (ED) visits for cellulitis/erysipelas in the United States. OBJECTIVE: To determine the prevalence, risk factors, complications, and cost of emergency care for cellulitis/erysipelas in the United States. METHODS: Cross-sectional study of the 2006 to 2016 National Emergency Department Sample, including a 20% sample of US ED visits (N = 320,080,467). RESULTS: The mean annual incidence of ED visits with a primary diagnosis of cellulitis/erysipelas was 2.42 to 3.55 per million adult and 1.14 to 2.09 per million pediatric ED visits. ED visits for cellulitis/erysipelas decreased significantly from 2006 to 2015 (Rao-Scott chi-square, P < .0001). ED visits with versus without a primary diagnosis of cellulitis/erysipelas were associated with public or no insurance and lower household income quartiles, and were more likely to occur during weekends and summer months. The mean cost of ED visits for cellulitis/erysipelas more than doubled in adults (from $720 to $1680) and tripled in children (from $939 to $2,823) from 2006 to 2016. ED visits for cellulitis/erysipelas were associated with multiple risk factors and increased infectious complications. LIMITATIONS: No data on cellulitis and erysipelas treatment or recurrence. CONCLUSION: There is a substantial and increasing burden of ED visits for cellulitis/erysipelas in the United States. Many ED visits occurred for uncomplicated cellulitis/erysipelas, in part because of health care disparities.

Skin and soft tissue infections, active component, U.S. Armed Forces, 2013-2016.

During the 4-year surveillance period, there were 282,571 incident cases of skin and soft tissue infection (SSTI) among active component U.S. military members diagnosed in inpatient or outpatient settings, corresponding to an overall incidence of 558.2 per 10,000 person-years (p-yrs). An additional 10,904 cases occurred in theater of operations (460.0 per 10,000 p-yrs). Approximately half (49.4%) were classified as "other SSTI" (e.g., folliculitis, impetigo); 45.9% were cellulitis/abscess; 4.6% were carbuncles/furuncles; and 0.1% were erysipelas. Annual incidence rates declined by 46.6% over the surveillance period. In general, higher rates of SSTIs were associated with younger age, recruit trainee status, and junior enlisted rank. During the surveillance period, 238,924 service members were treated for SSTIs in outpatient or inpatient settings, which accounted for 395,361 medical encounters and 19,213 hospital bed days. The history of operational significance of skin infections in the military, the high healthcare costs associated with evaluating and treating skin infections, and the risk of infections by antibiotic-resistant organisms highlight the importance of prevention, early diagnosis, and definitive treatment of skin infections, particularly in high-risk settings such as new recruit/basic training populations.

Clinical and epidemiological assessment of patients hospitalized for primary and recurrent erysipelas / Ocena kliniczna i epidemiologiczna pacjentów hospitalizowanych z powodu rózy pierwotnej i nawrotowej

INTRODUCTION: Erysipelas is a bacterial infection, caused by group A ß-hemolytic streptococci (Streptococcus pyogenes), rarely other bacteria. It is characterized by sudden onset and rapid course, with the presence of systemic symptoms. OBJECTIVE: A retrospective analysis of patients hospitalized for primary and recurrent erysipelas with particular consideration of clinical profile of patients, causes, complications and risk factors of the recurrence. MATERIAL AND METHODS: We have analyzed the medical records of patients hospitalized for erysipelas at the Dermatology and Venereology Department of the Medical University of Bialystok from 2011 to 2015. RESULTS: One hundred twenty female (53,8%) and 103 male (46,2%) were included in the study. The median age was 61. The first episode of clinical symptoms was observed in 78% patients, while 22% of them were diagnosed as recurrent erysipelas. Skin lesions in both cases were located in the lower extremities most often. Mechanical trauma was statistically more frequently cause of the disease in men, while venous insufficiency and ulcers in women. Complications such as abscess, ulceration, phlegmon and thrombosis were observed in 22% of patients, significantly more common in men. Patients who were hospitalized more than 10 days were more likely to have higher body mass index and higher indicators of inflammation than patients who required a shorter hospital stay. Recurrent erysipelas was more often diagnosed in patients with co-morbidities, including hypertension, overweight, venous insufficiency and diabetes. CONCLUSIONS: Erysipelas located in the lower extremities, high temperature on admission, higher indicators of the inflammation, complications and coexistence of obesity and diabetes are the risk factors of the prolonged hospital stay. Primary and recurrent erysipelas have a similar course, severity of the disease and duration of hospitalization.

Analysis of epidemiology, clinical features and management of erysipelas.

BACKGROUND: Erysipelas is a superficial form of cellulitis affecting the upper dermis and superficial lymphatics. The widespread use of antibiotics may affect clinical findings and response to therapy of infectious disorders. The purpose of the study was to investigate the epidemiological, clinical, and laboratory features of erysipelas and to compare the results of treatment with penicillin vs. other antibiotic regimens. METHODS: All charts of erysipelas patients treated at the University Hospital of Heraklion, Crete, Greece from 1994 to 2002 were retrospectively studied. RESULTS: Median age of the 99 patients was 54.5 years; 59% were females. The most frequent site involved was the lower extremity (76%), followed by the face (17%) and upper extremity (6%). In 61 patients (62%), a possible entry portal was identified. The most common manifestation of erysipelas was local symptoms and signs (pain, erythema, and swelling) in all patients, together with elevated erythrocyte sedimentation rate (ESR) (60%). Fever was present in 25% of patients. The most commonly used antibiotic was intravenous penicillin G (64%). In the penicillin group, mean duration of fever after treatment initiation was shorter than in the nonpenicillin group (1.7 vs. 4.5 days, P = 0.002). Both treatment failures and recurrences were the same between the two groups. DISCUSSION: The diagnosis of erysipelas can be based on careful examination for local signs and symptoms. The role of ESR in primary diagnosis needs further investigation. Penicillin seems to preserve its fundamental role in the treatment of disease.

Burden of illness of bacterial cellulitis and erysipelas of the leg in the Netherlands.

BACKGROUND: Information on the prevalence of bacterial cellulitis (BC) and erysipelas (ER) of the leg (BCERL) is sparse and dependent on the definitions used. There is no information available on the number of hospitalized and non-hospitalized patients with BCERL, and related treatment costs. OBJECTIVE: The purpose of this study was to assess the burden of illness for BCERL in the Netherlands in 2001. METHODS: Data were obtained from different linked databases. Hospital information was obtained from the National Morbidity Registration (known in the Netherlands as the LMR), which includes all Dutch citizens, using ICD-9-CM codes. The number of patients not admitted to hospital was estimated using a subsample with data from general practitioners (GPs) (N = 50,000). These data were extrapolated using age/gender and disease-specific standardization. The subsample was used to assess the location of the infection. Reimbursement costs were available for all resources. RESULTS: In 2001, approximately 28,000 patients presented with either BC or ER of the leg. Of these patients, 2,200 were admitted to the hospital and 4-6% had two or more episodes of ER/BC in 2001. The average costs per hospitalization for BCERL were 5,346 euros, accumulating to more than 14 million euros in 2001. Although only 7% of all patients were hospitalized, 83% of the total treatment costs could be attributed to hospitalization. CONCLUSIONS: BCERL are common and serious infections in the Netherlands. Hospitalization occurs in only one in 14 patients but contributes more than 80% of the total costs, which accumulate to 17 million euros a year.

[Incidence of erysipelas of the lower limbs in a spa resort. Efficacy of a strategy of sanitation education (La Lechere: 1992-1997)]. / Incidence de l'érysipèle des membres inférieurs en milieu thermal phlébologique. Efficacité d'une stratégie d'éducation sanitaire (La Léchère: 1992-1997).

OBJECTIVE: Erysipela is a common skin infection readily found in patients with venous insufficiency or lymphedema. The aim of this work was to measure the incidence of erysipela in a spa resort specialized in the treatment of venous and lymphatic diseases and to evaluate the influence of a preventive strategy principally based on education of patients at risk. PATIENTS AND METHODS: The measurement of incidence was based on the detection of the reasons for which the patients did not attend their thermal care sessions. Quality control was obtained from the reports of cases diagnosed by local private and public health care centers. RESULTS: The incidence of erysipela in this high risk population was 40.2 and 48.5 cases for 1000 persons per exposure-year in 1993 and 1994 respectively. The preventive strategy carried out was able to induce a reduction of 65% during the next years (p<0.01). CONCLUSION: This study confirms the high incidence of erysipela in subjects with severe venous insufficiency or lymphedema and the efficacy of an active educational preventive strategy.
