Abstract
INTRODUCTION Necrotizing soft tissue infections (NSTI) are increasing, posing a significant risk of morbidity and mortality. Due to nonspecific symptoms, a high index of suspicion is crucial. Treatment involves a multidisciplinary approach, with broad-spectrum antibiotics, early surgical debridement, and life support. This study analyzes the characteristics, demographics, complications, and treatment of NSTI in a hospital in Madrid, Spain. METHODS A retrospective observational study was conducted, including all surgically treated NSTI patients at our center from January 2016 to December 2022, examining epidemiological and clinical data. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) was prospectively calculated for all patients. RESULTS Twenty-two patients (16 men, 6 women, mean age 54.8) were included. Median time from symptom onset to emergency room visit was 3.5 days. All reported severe treatment-resistant pain; sixteen had fever exceeding 37.8°C (72.7%). Skin lesions occurred in twelve (54.5%), and thirteen had hypotension and tachycardia (59.1%). Treatment involved resuscitative support, antibiotherapy, and radical debridement. Median time to surgery was 8.25h. Intraoperative cultures were positive in twenty patients: twelve Streptococcus pyogenes, four Staphylococcus aureus, one Escherichia coli, and four polymicrobial infection. In-hospital mortality rate was 22.73%. CONCLUSIONS We examined the correlation between our results, amputation rates and mortality with LRINEC score and time to surgery. However, we found no significant relationship unlike some other studies. Nevertheless, a multidisciplinary approach with radical debridement and antibiotic therapy remains the treatment cornerstone. Our hospital stays, outcomes and mortality rates align with our literature review, confirming high morbimortality despite early and appropriate intervention.

Abstract
Objective: In this study, we seek to identify patient characteristics associated with limb loss and mortality while exploring the potential impact a multidisciplinary care team may have. Approach: This was a 10-year retrospective review of patients presenting to our tertiary care center for limb salvage with a diagnosis of lower extremity (LE) necrotizing fasciitis (NF). Patient demographics, clinical history, and outcomes were compared between survivors and nonsurvivors and between those who underwent LE amputation and those who did not. The article adheres to the strengthening the reporting of observational studies in epidemiology statement. Results: Sixty-two patients presented to our tertiary care center for limb salvage with LE NF. Forty-two patients underwent LE amputation: 27 (43.5%) underwent below-knee amputation, 1 (1.6%) underwent above-knee amputation, 8 (12.9%) underwent transmetatarsal amputation and 2 (3.2%) underwent calcanectomy. The overall mortality rate was 16.1% (n = 10). Risk factors for mortality included increased age (p = 0.034), higher Charlson Comorbidity Index (p = 0.011), thrombocytopenia (p = 0.002), hypotension (p = 0.015), erythema (p = 0.010), pain (p = 0.027), diabetes mellitus (p = 0.012), and malignancy (p < 0.001). Risk factors for LE amputation included DM (p = 0.017), peripheral vascular disease (p = 0.033), and an elevated laboratory risk indicator for necrotizing fasciitis (LRINC) (p = 0.033). Innovation: To identify outcomes after admission to a tertiary hospital with a dedicated limb salvage team with LE NF and to analyze risk factors for mortality and amputation. Conclusions: This is a comprehensive analysis of risk factors for mortality and amputation after LE NF. Our institution's experience highlights the importance of a multidisciplinary approach in the care of these patients.

Novel Clinical Risk Scoring Model for Predicting Amputation in Patients With Necrotizing Fasciitis: The ANF Risk Scoring System. Front Med (Lausanne) 2021; 8:719830. [PMID: 34869417 PMCID: PMC8639526 DOI: 10.3389/fmed.2021.719830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2021] [Accepted: 10/18/2021] [Indexed: 11/22/2022] Open
Abstract
Background: Necrotizing fasciitis (NF) is a life-threatening infection of the skin and soft tissue that spreads quickly and requires immediate surgery and medical treatment. Amputation or radical debridement of necrotic tissue is generally always required. The risks and benefits of both the surgical options are weighed before deciding whether to amputate or debride. This study set forth to create an easy-to-use risk scoring system for predicting the risk scoring system for amputation in patients with NF (ANF). Methods: This retrospective study included 1,506 patients diagnosed with surgically confirmed NF at three general hospitals in Thailand from January 2009 to December 2012. All diagnoses were made by surgeons who strictly observed the guidelines for skin and soft tissue infections produced by the Infectious Diseases Society of America. Patients were randomly allocated to either the derivation (n = 1,193) or validation (n = 313) cohort. Clinical risk factors assessed at the time of recruitment were used to create the risk score, which was then developed using logistic regression. The regression coefficients were converted into item scores, and the total score was calculated. Results: The following four clinical predictors were used to create the model: female gender, diabetes mellitus, wound appearance stage 3 (skin necrosis and gangrene), and creatinine ≥1.6 mg/dL. Using the area under the receiver operating characteristic curve (AuROC), the ANF system showed moderate power (78.68%) to predict amputation in patients with NF with excellent calibration (Hosmer-Lemeshow χ2 = 2.59; p = 0.8586). The positive likelihood ratio of amputation in low-risk (score ≤ 4) and high-risk (score ≥ 7) patients was 2.17 (95%CI: 1.66–2.82) and 6.18 (95%CI: 4.08–9.36), respectively. The ANF system showed good performance (AuROC 76.82%) when applied in the validation cohort. Conclusion: The developed ANF risk scoring system, which includes four easy to obtain predictors, provides physicians with prediction indices for amputation in patients with NF. This model will assist clinicians with surgical decision-making in this time-sensitive clinical setting.

Utility of the Lactate/Albumin Ratio as a Predictor for Mortality in Necrotizing Fasciitis Patients. Emerg Med Int 2021; 2021:3530298. [PMID: 34691782 PMCID: PMC8528631 DOI: 10.1155/2021/3530298] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Accepted: 10/07/2021] [Indexed: 12/14/2022] Open
Abstract
Background The lactate/albumin (L/A) ratio has been proposed as a prognostic marker because the ratio is associated with multiple organ failure and mortality in critically ill patients. We aimed to investigate the clinical utility of the L/A ratio as a good prognostic indicator of mortality in a cohort of necrotizing fasciitis patients. Method This retrospective study was conducted in two tertiary hospitals in Taiwan between 2015 and 2020. We reviewed adult patients with measured serum lactate and albumin on the emergency department (ED) arrival to evaluate the prognostic performance of the lactate and lactate/albumin (L/A) ratio for outcome prediction. Result Of the 262 NF patients, 20 (7.63%) died in the hospital. The area under the receiver operating characteristic curve (AUROC) value of the L/A ratio (0.76, 95% confidence interval [CI] 0.69–0.81, P < 0.01) was higher than lactate alone (0.71, 95% CI 0.65–0.74 P < 0.01) for predicting in-hospital mortality. The optimal cutoff of the L/A ratio was 1.61. The AUROC value of the L/A ratio was better than lactate alone regardless of normal lactate level. The cutoff of L/A ratio and hypoalbuminemia showed further discriminative value for in-hospital mortality even in patients with normal lactate levels. Conclusion The prognostic performance of the L/A ratio was superior to a single measurement of lactate for predicting in-hospital mortality and intensive care unit (ICU) lengths in necrotizing fasciitis patients. Aggressive intervention and intensive care were necessary for high-risk NF patients upon ED arrival.

Abstract
This is a case of necrotizing soft tissue infection (NSTI) due to S. pyogenes. Exploration and subsequent debridement led to the limb preservation. Early surgery is crucial for effective treatment of NSTI. Non-necrotizing STI due to S. pyogenes could be possible to reccure at the same limb 2 months later. The patient received antimicrobial treatment without surgery and recovered.
Background Group A Streptococcus pyogenes (GAS) causes necrotizing soft tissue infections (NSTIs) necessitating exploration, surgical debridement, and possibly limb amputation. Case presentation A 45-year-old man presented with traumatic injury of the left carpal region, vomiting, and diarrhea. The swelling and pain in the left forearm worsened with sensorimotor deficits, and his skin color deteriorated. Emergent exploration was performed for limb preservation; GAS was detected in an exudate, and debridement was performed on postoperative day 2 for streptococcal toxic shock syndrome. He recovered uneventfully and was discharged; however, he returned after 2 months with GAS-induced STI at the same site and received antimicrobial treatment. Conclusion Exploration and subsequent debridement are crucial for effective treatment of NSTI.

Abstract
BACKGROUND AND OBJECTIVE To assess the usefulness of a risk scale based on serum procalcitonin (PCT) compared to the Laboratory Risk Indicator for Necrotising Fasciitis (LRINEC) scale in the early discrimination between necrotising fasciitis (NF) and cellulitis of the extremities. MATERIALS AND METHODS Retrospective study of consecutive patients with confirmed diagnosis of NF in one limb (n=11). This study group was compared with 23 consecutive patients with a diagnosis of severe limbs cellulitis during the same period. The clinical data and laboratory parameters were analysed, the main variable was the serum level of PCT upon admission. The capacity for NF diagnosis of the two methods, PCT level and LRINEC scale score, were evaluated by ROC curve and determined by the calculation of the area under the curve (AUC). RESULTS The AUC was significantly higher with PCT measurement, both as a continuous variable and when the risk was categorised. The cut-off point for the PCT level with the highest AUC under the curve was from 0.87ng/ml (sensitivity 90.9%, specificity 82.6%), whereas it was a score of 5 on the LRINEC scale (sensitivity 72.7%, specificity 82.6%). CONCLUSION PCT measurement was a more effective method than the LRINEC score for early discrimination between NF and cellulitis of the extremities. A low level of PCT, associated with the patient's clinical status and physical examination is especially useful to rule out an early diagnosis of NF.

Abstract
Lower extremity necrotizing fasciitis (NF) is a severe infection requiring immediate surgery. The aim of this study was to assess patient factors predictive of amputation and mortality in diabetes mellitus (DM) and non-DM patients with lower extremity NF. The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was reviewed retrospectively. Out of 674 patients with lower extremity NF, 387 had DM (57.4%). Patients with DM had lower mortality ( P = .004). Increased mortality was independently associated with age >60 years (adjusted odds ratio [aOR] = 3.96, 95% confidence interval [CI] = 1.69-9.77), partial thromboplastin time >38 seconds (aOR = 2.66, 95% CI = 1.09-6.62), albumin <2.0 mg/dL (aOR = 2.84, 95% CI = 1.13-7.37), coagulopathy (aOR = 3.29, 95% CI = 1.24-9.19), higher anesthesia risk category (aOR = 3.08, 95% CI = 1.18, 8.59), chronic obstructive pulmonary disease (aOR = 3.46, 95% CI = 1.13-10.9), postoperative acute respiratory distress syndrome (aOR = 5.24, 95% CI = 2.04-14.4), and postoperative septic shock (aOR = 5.14, 95% CI = 1.94-14.1). Amputation was independently associated with DM (aOR = 4.35, 95% CI = 2.63-7.35) but not mortality. Although DM was associated with more amputations for lower extremity NF, patients with DM had lower mortality than non-DM patients in the bivariate analysis. Further research is needed to investigate outcomes among DM and non-DM patients in the context of lower extremity NF.

Abstract
Objectives: Necrotizing fasciitis (NF) is a rare but limb- and life-threatening soft-tissue infection. It is among the most challenging surgical infections faced by surgeons, and is often accompanied by severe systemic toxicity. The aim of this study was to evaluate the predictive power of serum lactate and creatinine levels for mortality and morbidity in lower extremity NF. Methods: A retrospective cohort analysis of 87 patients with lower extremity NF was performed to evaluate the management techniques and the amputation and survival rates according to serum lactate and creatinine levels as well as the time between the onset of symptoms and surgery. Results: The mean time between the onset of symptoms and surgery was 3.7 days. As the time between the onset of symptoms and surgery increased, the rate of amputation and mortality significantly increased (p<0.001). In all, 66% of the mortality in the group was seen among the 12 patients who had a serum creatinine level greater than 2 mg/dL at the time of presentation. In 12 of 14 patients (85.7%) who underwent amputation/disarticulation, the mean serum lactate level was 5.7 mmol/L (range: 5.1-8.7 mmol/L), and the mean serum creatinine level was 1.92 mg/dL (range: 1.4 to.3.3 mg/dL). The high levels of serum creatinine and lactate were found to be statistically significant in terms of predicting mortality and amputation (p<0.001). Conclusion: Based on the results of this study, it was determined that risk factors for mortality include age, late presentation, increased serum creatinine and lactate levels, and that these factors can predict the rate of death from NF at the time of presentation.

Abstract
Background:
Necrotizing soft tissue infection is a surgical emergency associated with high mortality. Its presence in patients with risk factors for peripheral arterial disease such as diabetes mellitus is consistently associated with significantly poorer outcomes. Though it has been over a century since it was initially described in the literature, mortality rates remain high and treatment regimens are not standardized.
Materials and methods:
PubMed and Cochrane databases were searched for articles pertaining to necrotizing soft tissue infections. Articles were screened for relevance with the intent to compare outcomes in prospective studies of patients with diabetes mellitus or peripheral arterial disease. Patient demographics, clinical findings, mortality, rates of amputation, and morbidity were intended to be compared.
Results:
857 articles were identified, 165 duplicates were removed, and 6 prospective trials were identified for inclusion. Due to significant paucity of data, patient heterogeneity, and lack of standardization for surgical management, a descriptive review of the literature in relation to necrotizing soft tissue infections was pursued, with a focus on high-risk patients with peripheral arterial disease or diabetes mellitus.
Conclusions:
Early aggressive surgical intervention or major amputation may reduce mortality at the cost of increased disability and poorer quality of life in the long term, and may be appropriate in vasculopaths with poorly controlled diabetes and rapidly progressive fulminant infection. However, there is a deficiency in high-level evidence supporting surgical decision-making in this setting, with no standardized protocols for amputation. Future research will be needed to clarify the patient population who would benefit from radical amputation versus intention for limb salvage.

Abstract
Introduction: Fasciitis of the limb and toxic-shock syndrome due to Streptococcus Pyogenes infection is considered a surgical emergency. This condition may occur in previously healthy patients. It is a life-threatening condition with high morbidity rates when treatment is delayed due to poor diagnosis and non-surgical intervention. Case Report: 17-year-old male patient sustained a minor ankle trauma while skating. Initials findings were a 1cm wound in relation with his left lateral malleolus and moderate swelling. About 6 h later, the patient was admitted at the emergency room with disproportionate limb pain, increased swelling, persistent fever, paleness, tachycardia, and hypotension. The patient was intubated due to his unstable hemodynamic condition and underwent fasciotomy of the limb. A vacuum-assisted closure device was used. After the first surgical procedure, patient’s condition radically improved. He was extubated with good clinical prognosis. He underwent several surgical procedures in a 3-weeks lapse until the wound finally healed. Conclusion: Streptococcal toxic-shock syndrome and limb fasciitis have no specific early signs or symptoms. It seems that clinical dissociation (disproportionate pain together with a minor wound) should become an alarm sign to trauma surgeons. It is important to contemplate this serious condition as differential diagnosis in every patient undergoing trauma with torpid evolution. Aggressive surgical management is the gold standard treatment and should not be delayed.

Abstract
Necrotizing fasciitis (NF) patients are increasingly managed in burn units. Although treated similarly to burns, the healthcare resource utilization (HRU) in NF appears to be greater. Accurate knowledge of the HRU is important to better allocate resources and to compare outcomes between units. The goal of this study is to provide better understanding of the HRU for NF compared with burns. A retrospective chart review of patients ≥18 years admitted to two regional tertiary referral centers with either NF or burns requiring surgery. The authors examined age, sex, %TBSA, geographic region, anatomical location, length of stay (LOS) in hospital, LOS in intensive care unit, number of operative procedures, number of packed red blood cells transfused, amputation, death, and use of free tissue transfer or skin graft. There were 210 NF and 209 burn patients. The NF cohort had a smaller TBSA (3.3 vs 10.0%), longer LOS (20 vs 14 days), and consequently a longer LOS/%TBSA (6.0 vs 1.5 days). This difference persisted after adjusting for age. More of the NF cohort (44.8%) spent ≥1 day in the intensive care unit. The NF cohort also had more procedures (median 2 vs 1), required blood (46.2 vs 16.7%), died in hospital (13.3 vs 4.3%), had an amputation (12.4 vs 4.8%), or required free tissue transfer (7.6 vs 2.9%). This study shows that NF requires substantially more HRU compared with burns. This information is important in recognizing the impact of these patients on burn units and planning for allocation of appropriate resources.

Abstract
Patients with diabetes are at a higher risk of having diabetic foot ulcers (DFUs) or necrotizing fasciitis (NF). The present study aims to examine the clinical characteristics and associated risk factors for lower-extremity amputation (LEA) in patients with DFU complicated by NF.We retrospectively reviewed patients treated at a major diabetic foot center in Taiwan between 2009 and 2014. Of the 2265 cases 110 had lower-extremity NF. Limb preservation outcomes were classified as major LEA, minor LEA, or limb-preserved. Clinical characteristics, laboratory data, and bacterial culture results were collected for analysis.Of the 110 patients with NF, 100 had concomitant DFUs (NF with DFU) and the remaining 10 had no DFU (NF without DFU). None of the NF patients without DFU died nor had their leg amputated. Two NF patients with DFU died of complications. The amputation rate in the surviving 98 NF patients with DFU was 72.4% (46.9% minor LEA and 25.5% major LEA). Seventy percent of the NF patients without DFU had monomicrobial infections (60% with Streptococcus species), and 81.4% NF patients with DFU had polymicrobial infections. Anaerobic organisms were identified in 66% of the NF patients with DFU. Multinomial logistic regression analysis revealed an association between high-grade Wagner wound classification (Wagner 4 and Wagner 5) and LEA (adjusted odds ratio [aOR] = 21.856, 95% confidence interval [95% CI] = 1.625-203.947, P = 0.02 and aOR = 20.094, 95% CI = 1.968-205.216, P = 0.01 for major and minor LEA, respectively) for NF patients with DFU. In addition, a lower serum albumin level was associated with major LEA (OR = 0.066, P = 0.002).In summary, once DFUs were complicated by NF, the risk of amputation increased. Empirical treatment for NF patients with DFU should cover polymicrobial infections, including anaerobic organisms. The high-grade wound classification and low serum albumin level were associated with LEA.

Abstract
BACKGROUND Necrotizing soft-tissue infection (NSTI) is uncommon but life-threatening. A recent meta-analysis estimated the overall mortality at 23.5%. OBJECTIVE We sought to identify risk factors associated with mortality in a cohort of patients with NSTI in a tertiary care center. METHODS We identified 512 patients with NSTI between 1996 and 2012 in the national hospital database Program for Medicalization of Information Systems and examined risk factors of mortality with NSTI by univariate and multivariate analysis. RESULTS We included 109 patients with a confirmed diagnosis of NSTI; 31 (28%) died at a median follow-up of 274 days (range 2-6135 days). On multivariate analysis, independent risk factors of mortality were age older than 75 years (hazard ratio [HR] 4.4, 95% confidence interval [CI] 1.8-10.3), multifocal NSTI (HR 5.9, 95% CI 1.9-18.5), severe peripheral vascular disease (HR 5.1, 95% CI 1.5-17.0), hospital-acquired infection (HR 3.9, 95% CI 1.4-10.7), severe sepsis (HR 7.4, 95% CI 1.7-33.1), and septic shock on hospital admission (HR 13.9, 95% CI 3.8-50.4). LIMITATIONS This was a retrospective cohort, which disallows a precise record of the delay between diagnosis and surgery. CONCLUSION Our findings for this robust cohort of patients with a definite diagnosis of NSTI could help clinicians stratify NSTI severity at clinical course onset.

Abstract
BACKGROUND Necrotizing fasciitis is an infectious process characterized by rapidly progressing necrosis of superficial fascia and subcutaneous tissue with subsequent necrosis of overlying skin.Necrotizing fasciitis is a rare but fatal infection. The worldwide incidence is at 0.4 per 100,000. Mortality is up to 80% with no intervention, and 30-50% with intervention. Delay in intervention is associated with poor outcome. The risk factors for necrotizing fasciitis are diabetes mellitus, HIV, malignancy, illicit drug use, malnutrition among others.The aim of this study was to describe the clinical presentation and early outcomes of necrotizing fasciitis amongst Ugandan patients. METHODS A prospective descriptive case series study conducted at Mulago National Referral and Teaching hospital from 5th January to 30th April 2011. Patients with necrotizing fasciitis were consecutively recruited after clinical evaluation, laboratory and microbiological tests were performed. Aggressive debridement was done and broad-spectrum antibiotics administered. Patients were followed up on surgical wards. Ethical approval was obtained. RESULTS Thirty five patients were recruited over a 4 months period. More males were affected with, M: F 3:1. The 20-40 years age group was most affected. Attainment of healthy granulation tissue took 19 days on average. Mortality rate was 14% (5/35). Limbs were the most affected body parts 20/35 (57%), the scrotum and perineum (23%). Among infants the scalp was the most affected. Co-morbidities included HIV 8/35 (17%), and DM (5%) among others. The commonest organisms were gram negative. Split skin grafting was necessary in 74% (26/35) of patients. CONCLUSION There were a high number of patients with necrotizing fasciitis; it was associated with low mortality but high morbidity (long hospital stay). There was a high preponderance to males and limbs were the more affected body parts.

Abstract
Chronic lymphedema and lymphangitis are common adverse effects following treatment for gynecological cancer. Because the early symptoms of necrotizing fasciitis are similar to those of lymphangitis, fatal outcome can occur if patients or physicians underestimate this condition. Here, we present a case of necrotizing fasciitis in a patient with chronic lymphedema.

Abstract
Necrotizing fasciitis is a lethal soft tissue infection for its rapid progression to septic shock. We present a 59-year-old male on chronic hemodialysis (HD). We made the diagnosis of necrotizing fasciitis of the right thigh due to the crepitus from physical examination and subcutaneous emphysema from an X film. He was successfully treated with antibiotics and surgical debridement. The blood and surgical drainage cultures showed Escherichia coli, which is less commonly seen in cutaneous infection. The colonoscopic finding revealed adenomatous polyps. Necrotizing fasciitis in patients on HD requires early diagnosis and aggressive treatment to ensure the favorable clinical outcomes.

Abstract
Necrotizing fasciitis belongs to a group of complicated soft tissue infections that can be even life threatening. Despite growing knowledge about its etiology, predictors, and the clinical progression, the mortality remains at a high level with 20%. A relevant reduction can be achieved only by an early diagnosis followed by consistent therapy. The clinical findings in about 75% of the cases are pain out of proportion, edema and tenderness, blisters, and erythema. It is elementary to differentiate a necrotizing or a non-necrotizing soft tissue infection early. In uncertain cases it can be necessary to perform a surgical exploration to confirm the diagnosis. The histopathologic characteristics are the fascial necrosis, vasculitis, thrombosis of perforating veins, the presence of the disease-causing bacteria as well as inflammatory cells like macrophages and polymorphonuclear granulocytes. Secondly, both the cutis and the muscle can be affected. In many cases there is a disproportion of the degree of local and systemic symptoms. Depending on the infectious agents there are two main types: type I is a polymicrobial infection and type II is a more invasive, serious, and fulminant monomicrobial infection mostly caused by group A Streptococcus pyogenes.Invasive, severe forms of streptococcal infections seem to occur more often in recent years. Multimodal and interdisciplinary therapy should be based on radical surgical débridement, systemic antibiotic therapy as well as enhanced intensive care therapy, which is sometimes combined with immunoglobulins (in streptococcal or staphylococcal infections) or hyperbaric oxygen therapy (HBOT, in clostridial infections). For wound care of extensive soft tissue defects vacuum-assisted closure has shown its benefit.
