Staphylococcal scalded skin syndrome: Clinical features, ancillary testing, and patient management.

BACKGROUND/OBJECTIVES: The utility of ancillary testing in improving diagnostic precision or improving patient outcomes in staphylococcal scalded skin syndrome (SSSS) is unclear. Similarly, an optimal antibiotic regimen has yet to be established. Our goal was to describe clinical characteristics and ancillary work-up of SSSS, report bacterial resistance patterns, and examine patient outcomes under varying therapeutic strategies with the aim of developing an evidence-based management algorithm. METHODS: We performed a retrospective review of pediatric patients diagnosed with SSSS at Intermountain Healthcare facilities between 2010 and 2021. A Kruskal-Wallis rank sum test was used to assess median length of stay between different antibiotic regimens. RESULTS: Eighty-five cases were identified. The most common ancillary tests obtained were a complete blood count (88%), followed by chemistry analysis (80%). Blood cultures were collected in more patients (79%) compared to aerobic cultures (60%). No blood culture was positive for Staphylococcus aureus. All S. aureus isolates were methicillin-sensitive. Of those found resistant to clindamycin (36%), all demonstrated macrolide-induced clindamycin resistance. None were constitutively resistant to clindamycin. There was no statistical difference between antibiotic regimen and length of stay (p = .691). Receiving opiate medications was the only risk factor associated with prolonged hospitalization (p = .001). CONCLUSIONS: Ancillary testing does not improve diagnostic precision and can be reduced. Clindamycin does not improve patient outcomes, suggesting beta-lactams should be considered first line. Susceptibility patterns in our cohort demonstrate inducible clindamycin resistance as opposed to constitutive.

Staphylococcal Scalded Skin Syndrome, Identification, and Wound Care: A Case Report Series.

INTRODUCTION: Methicillin-susceptible Staphylococcus aureus (MSSA) infections cause diseases ranging from localized skin infections to serious invasive infections. Neonates are immunosuppressed, placing them at increased risk for MSSA infections, including staphylococcal scalded skin syndrome (SSSS), a rare severe skin presentation of MSSA. CLINICAL FINDINGS: We present a case series of 3 preterm infants with SSSS receiving care at a level 3 neonatal intensive care unit. PRIMARY DIAGNOSIS: The infants presented with symptoms of sepsis, including temperature instability, apnea, and bradycardia episodes. The infants had peeling skin at sites of external pressure, including peripheral intravenous (IV) sites, under dressings, or where devices had been in contact with skin. INTERVENTIONS: The infants were soaked in a tub with gel baby wash and water to remove leads without traumatizing the skin. Laboratory values were drawn, and cultures were obtained. Wound care was provided using mupirocin, soft silicone mesh wound contact layer, and soft cotton bandage gauze. Supportive respiratory care was provided, and IV antibiotics were administered. OUTCOMES: The infants were discharged to their homes with intact skin. One infant experienced a loss of pigment that persisted several weeks. All patients were without scarring by early childhood. PRACTICE RECOMMENDATIONS: Thorough assessment and careful hygiene of neonates' skin is crucial. MSSA is an infection that can appear on the skin. It is important to quickly diagnose and treat this type of infection, especially when it presents as a localized pustule, boil, tear, peeling, or crust before it becomes systemic.

Staphylococcal Scalded Skin Syndrome and Bullous Impetigo.

Staphylococcal scalded skin syndrome (SSSS) and bullous impetigo are infections caused by Staphylococcus aureus. The pathogenesis of both conditions centers around exotoxin mediated cleavage of desmoglein-1, which results in intraepidermal desquamation. Bullous impetigo is due to the local release of these toxins and thus, often presents with localized skin findings, whereas SSSS is from the systemic spread of these toxins, resulting in a more generalized rash and severe presentation. Both conditions are treated with antibiotics that target S. aureus. These conditions can sometimes be confused with other conditions that result in superficial blistering; the distinguishing features are outlined below.

[Staphylococcal scalded skin syndrom: a case report]. / Syndrome de Lyell staphylococcique: à propos d'un cas.

Staphylococcal scalded skin syndrom is a bullous dermatosis induced by exfoliating staphylococcal exotoxins. Children are most often affected. We report the case of a 6-month-old infant who had angina in the few days before leading up to bullous erythroderma and whose skin biopsy showed characteristic appearance of staphylococcal scalded skin syndrom. The development was rapidly unfavourable and the infant died in a refractory septic shock chart, despite the introduction of norepinephrine and anti-SAMR antibiotic therapy. The term staphylococcal scalded skin syndrome (SSSS) was separated from the toxic or allergic epidermal necrolysis by Lyell into the opposite anatomical aspect of these two entities: in scalded skin syndrome, Skin detachment is done by cleavage of the superficial part of the epidermis at the granular layer, while in toxic Lyell syndrome, the cleavage sits deeper at the level of the mucous body.

Antibiotic-resistant profile and the factors affecting the intravenous antibiotic treatment course of generalized Staphylococcal Scalded Skin Syndrome: a retrospective study.

BACKGROUND: Staphylococcal Scalded Skin Syndrome (SSSS) is caused by a special type of Staphylococcus aureus (S.aureus) which can produce exfoliative toxins. The generalized SSSS is recommended to be admitted and treated with intravenous antibiotics. However, there were limited reports on whether personal and clinical factors can have impacts on the duration of intravenous antibiotic application for pediatric patients with generalized SSSS. We performed a study to assess the factors affecting intravenous antibiotic treatment course of SSSS patients. Additionally, the positive culture rates of S.aureus in different samples and the antibiotic-resistant profile were investigated. METHODS: Two hundred nineteen patients with generalized SSSS were included. Gender, age, area, season, maximum axillary temperature, white blood cell (WBC) count, C-reactive protein (CRP) level, types of intravenous antibiotics, and types of external antibiotics were recorded as the baseline. Simple linear regression was applied in the univariate analysis to determine the variables with statistical significance and then these variables were further examined in multivariate linear regression model. The positive culture rates of S.aureus in different sample sources were calculated and the drug sensitivity results were statistically compared by pairwise Chi square test. RESULTS: According to the multiple linear regression, older ages (ß = - 0.01, p < 0.05) and external application of fusidic acid (ß = - 1.57, p < 0.05) were associated with shorter treatment course, elevated leukocytes (ß = 0.11, p < 0.001) and CRP level (ß = 1.64, p < 0.01) were associated with longer treatment course. The positive culture rates of periorificial swabs, throat swabs, and blood samples were 54.55, 30.77, and 5.97% respectively. The resistant rates of levofloxacin (8.33%), gentamycin (8.33%), tetracycline (25%), oxacillin (8.33%), vancomycin (0%) were significantly lower than the ones of erythromycin (100%), trimethoprim-sulfamethoxazole (TMP/SMX) (83.33%), clindamycin (91.67%), penicillin G(100%) (p < 0.001). CONCLUSION: Elevated leukocytes and CRP level indicated prolonged intravenous antibiotic treatment course. Older ages and external application of fusidic acid helped to reduce the treatment course. Compared with blood samples, the culture positive rates of S.aureus in periorificial and throat swabs were higher. Oxacillin and vancomycin resistance was rare and clindamycin resistance was common. Clindamycin monotherapy for SSSS should be avoided.

Demographic characteristics, clinical features, and optimal management of hospitalized patients with staphylococcal scalded skin syndrome.

BACKGROUND/OBJECTIVES: Optimal management of staphylococcal scalded skin syndrome (SSSS) has not been established. Clindamycin may benefit patients via inhibition of ribosomal toxin production, but resistance patterns suggest penicillinase-resistant penicillins or cephalosporins should be the first line. Our goal was to describe demographic and clinical characteristics of SSSS patients at our institution, delineate bacterial resistance patterns, and examine outcomes of varying therapeutic strategies in SSSS. METHODS: We performed a retrospective review of patients under the age of 18 with confirmed clinical SSSS diagnosis by the dermatology consult team at the University of North Carolina (UNC) Hospitals from January 2008 to April 2017. Median hospital and ICU length of stay (LOS) were compared using a Wilcoxon Rank Sum Test. RESULTS: We found 59 SSSS patients. Coverage with clindamycin and vancomycin versus absence of that combination was associated with shorter ICU LOS. Although trending toward reduced hospital LOS, this was not significantly altered with the use of vancomycin and clindamycin after adjustment for multiple comparisons. Individual use of either clindamycin or vancomycin did not significantly alter overall hospital or ICU LOS. Among 24 patients with a pathogen identified on culture, 18 (75.0%) revealed resistance to clindamycin, and 2 (8.3%) revealed MRSA. CONCLUSIONS: Clindamycin resistance is more prevalent in hospitalized SSSS patients compared to our pediatric outpatient population. The combination of vancomycin and clindamycin results in shorter ICU LOS. Individual use of clindamycin or vancomycin does not significantly reduce hospital or ICU LOS after adjustment for multiple comparisons.

Antibiotic Regimens and Associated Outcomes in Children Hospitalized With Staphylococcal Scalded Skin Syndrome.

BACKGROUND: Controversy exists regarding the optimal antibiotic regimen for use in hospitalized children with staphylococcal scalded skin syndrome (SSSS). Various regimens may confer toxin suppression and/or additional coverage for methicillin-susceptible Staphylococcus aureus (MSSA) or methicillin-resistant S aureus (MRSA). OBJECTIVES: To describe antibiotic regimens in hospitalized children with SSSS and examine the association between antistaphylococcal antibiotic regimens and patient outcomes. DESIGN/METHODS: Retrospective cohort study of children hospitalized with SSSS using the Pediatric Health Information System database (2011-2016). Children who received clindamycin monotherapy, clindamycin plus MSSA coverage (eg, nafcillin), or clindamycin plus MRSA coverage (eg, vancomycin) were included. The primary outcome was hospital length of stay (LOS); secondary outcomes were treatment failure and cost. Generalized linear mixed-effects models were used to compare outcomes among antibiotic groups. RESULTS: Of 1,259 children included, 828 children received the most common antistaphylococcal antibiotic regimens: clindamycin monotherapy (47%), clindamycin plus MSSA coverage (33%), and clindamycin plus MRSA coverage (20%). Children receiving clindamycin plus MRSA coverage had higher illness severity (44%) compared with clindamycin monotherapy (28%) and clindamycin plus MSSA (32%) (P =.001). In adjusted analyses, LOS and treatment failure did not differ among the 3 regimens (P =.42 and P =.26, respectively). Cost was significantly lower for children receiving clindamycin monotherapy and highest in those receiving clindamycin plus MRSA coverage (mean, $4,839 vs $5,348, respectively; P <.001). CONCLUSIONS: In children with SSSS, the addition of MSSA or MRSA coverage to clindamycin monotherapy was associated with increased cost and no incremental difference in clinical outcomes.

Antimicrobial Resistance and Molecular Analysis of Staphylococcus aureus in Staphylococcal Scalded Skin Syndrome among Children in Korea.

BACKGROUND: Staphylococcal scalded skin syndrome (SSSS) is a skin disease characterized by blistering and desquamation caused by exfoliative toxins (ETs) of Staphylococcus aureus (S. aureus). Although many countries show predominance of methicillin-susceptible S. aureus (MSSA), cases of methicillin-resistant S. aureus (MRSA) have been reported. METHODS: Twenty-six children aged <15 years diagnosed with SSSS from January 2010 to December 2017 from three hospitals were included. S. aureus isolates from cases were analyzed for multilocus sequence types and ETs. Medical records were reviewed for clinical characteristics, treatment, and antimicrobial susceptibility patterns of S. aureus. RESULTS: Among the 26 cases, mean age was 2.3 years. According to skin manifestations patients were classified as generalized (n = 10, 38.5%), intermediate (n = 11, 42.3%), and abortive (n = 5, 19.2%). Among all cases, 96.2% (25/26) were due to MRSA and the macrolide-resistance rate was 92.3% (24/26). ST89 (n = 21, 80.8%) was the most prevalent clone, followed by single clones of ST1, ST5, ST72, ST121, and ST1507. The eta gene was detected in one (3.8%) isolate which was MSSA. The etb gene was detected in 14 (53.8%) isolates, all of which were ST89. Nafcillin or first-generation cephalosporin was most commonly prescribed (n=20, 76.9%). Vancomycin was administered in four patients (15.4%) and clindamycin in nine patients (34.6%). Among MRSA cases, there was no difference in duration of treatment when comparing the use of antimicrobials to which the causative bacteria were susceptible or non-susceptible (9.75 vs. 8.07 days, P > 0.05). CONCLUSION: S. aureus isolated from children with SSSS in Korea demonstrated a high prevalence of methicillin-resistant ST89 clones that harbored the etb gene. The predominance of MRSA suggests that antibiotics to which MRSA are susceptible may be considered for empirical antibiotic treatment in children with SSSS in Korea. Further studies on the role and effectiveness of systemic antibiotics in SSSS are warranted.

Staphylococcal scalded skin syndrome: An epidemiological and clinical review of 84 cases.

BACKGROUND: Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated, blistering skin disorder that mainly affects infants and children. There is limited literature regarding pediatric SSSS. The purpose of this study was to describe the epidemiology, clinical features, and management of pediatric SSSS. METHODS: Retrospective cohort study of pediatric patients with a clinical diagnosis of SSSS seen at the Hospital for Sick Children in Toronto, Ontario, Canada, from January 1994 to March 2016. RESULTS: We included 84 patients with a clinical diagnosis of SSSS; 49/84 (58%) were male. Mean age of diagnosis was 3.1 ± 2.4 years. All patients presented with erythema and exfoliation, while 64/84 (76%) presented with vesicles/ bullae. Skin tenderness was the most common symptom, present in 68/84 (81%) subjects. Staphylococcus aureus was more commonly isolated from periorificial cultures than from bullae. Mean hospitalization was 4.7 ± 2.3 days. No difference was found in admission duration between children receiving clindamycin and those that did not (3.6 ± 2.2 vs 3.9 ± 2.34 days, P = .63). Skin debridement was the only risk factor leading to more complications and prolonged hospitalization (P = .03). Severe complications were seen in 4 (5%) cases, and no fatalities were observed. CONCLUSIONS: Healthcare providers should be aware of SSSS and consider it in the differential diagnosis of infants and children with new onset erythema, exfoliation, and/or vesiculation. Suspected culprit pathogens were more often obtained from periorificial swabs; however, these isolates were not tested for exfoliative toxin to confirm causality. Antibiotic treatment should be guided by sensitivity testing. Addition of clindamycin as an anti-toxin agent had no effect on the duration of hospitalization, and this should be further investigated. Surgical debridement of the skin in patients with SSSS should be discouraged.

Increasing Numbers of Staphylococcal Scalded Skin Syndrome Cases Caused by ST121 in Houston, Texas.

BACKGROUND: The molecular epidemiology of Staphylococcus aureus strains causing staphylococcal scalded skin syndrome (SSSS) in the United States has not been described. We analyzed patient and S. aureus isolate characteristics associated with SSSS in children at Texas Children's Hospital. METHODS: Patients with SSSS were identified by ICD9/10 codes and available S. aureus isolates were identified from an ongoing S. aureus surveillance study. Medical records were reviewed for 58 patients with available S. aureus isolates. Isolate analyses included PCR for agr group, pvl (lukSF-PV), tst, eta and etb, pulsed-field gel electrophoresis, multi-locus sequence typing and antimicrobial susceptibilities. RESULTS: Cases of SSSS increased from 2.3/10,000 admissions in 2008 to 52.6/10,000 admissions in 2017 (P < 0.0001). The 58 study cases (57 methicillin-susceptible S. aureus, 1 MRSA) with isolates were from 2013 to 2017. The majority (88%) of isolates was of clonal cluster (CC) 121, agr group IV, pvl, tst and carried eta and/or etb and 26% were clindamycin resistant. Twelve ST121 isolates had high level resistance to mupirocin. Patients were treated with standard supportive care plus systemic antibiotics [clindamycin alone or in combination with another antibiotic (n = 44)]. One patient had a recurrent SSSS and one patient was transferred to a burn unit on day 3. CONCLUSIONS: Cases of SSSS are increasing at our hospital. Most S. aureus strains isolated were of one CC, CC121 and carried eta and etb. Supportive care plus clindamycin was effective treatment. We speculate that CC121 was recently introduced to our region and is responsible for the increasing numbers of SSSS cases observed at Texas Children's Hospital.

Antibiotic sensitivity and clinical outcomes in staphylococcal scalded skin syndrome.

Staphylococcal scalded skin syndrome causes widespread skin denudation primarily in infants < 1 year old. Selection of empiric therapy is complicated by rising rates of antibiotic resistance in community-acquired staphylococcal infections. Consistent with a previous study, this retrospective review found that SSSS-associated isolates were more likely to be clindamycin-resistant and less likely to be methicillin-resistant compared to overall staphylococcal infections. We favor cephalosporins and penicillinase-resistant penicillins (eg, oxacillin) for empiric management of SSSS, with consideration of adding MRSA coverage in communities with high MRSA prevalence or failure to improve following several days of treatment.

Newborn with desquamating rash.

A 9-day-old boy was brought to the emergency department by his mother. The infant had been doing well until his most recent diaper change when his mother noticed a rash around the umbilicus, genitalia, and anus. The infant was born at term via spontaneous vaginal delivery. The pregnancy was uncomplicated; the infant's mother was group B strep negative. Following a routine postpartum course, the infant underwent an elective circumcision before hospital discharge on his second day of life. There were no interval reports of irritability, poor feeding, fevers, vomiting, or changes in urine or stool output.

Staphylococcal-scalded skin syndrome: evaluation, diagnosis, and management.

BACKGROUND: Staphylococcal-scalded skin syndrome (SSSS), also known as Ritter disease, is a potentially life-threatening disorder and a pediatric emergency. Early diagnosis and treatment is imperative to reduce the morbidity and mortality of this condition. The purpose of this article is to familiarize physicians with the evaluation, diagnosis, and treatment of SSSS. DATA SOURCES: A PubMed search was completed in Clinical Queries using the key terms "Staphylococcal scalded skin syndrome" and "Ritter disease". RESULTS: SSSS is caused by toxigenic strains of Staphylococcus aureus. Hydrolysis of the amino-terminal extracellular domain of desmoglein 1 by staphylococcal exfoliative toxins results in disruption of keratinocytes adhesion and cleavage within the stratum granulosum which leads to bulla formation. The diagnosis is mainly clinical, based on the findings of tender erythroderma, bullae, and desquamation with a scalded appearance especially in friction zones, periorificial scabs/crusting, positive Nikolsky sign, and absence of mucosal involvement. Prompt empiric treatment with intravenous anti-staphylococcal antibiotic such as nafcillin, oxacillin, or flucloxacillin is essential until cultures are available to guide therapy. Clarithromycin or cefuroxime may be used should the patient have penicillin allergy. If the patient is not improving, critically ill, or in communities where the prevalence of methicillin-resistant S. aureus is high, vancomycin should be used. CONCLUSION: A high index of suspicion is essential for an accurate diagnosis to be made and treatment promptly initiated.
