Necrotizing fasciitis in a renal transplant patient

We have described a 28-year-old diabetic woman who had necrotizing fasciitis of the perineum three years after receiving a living related renal transplant. The diagnosis of necrotizing fasciitis was made early and she was referred to a tertiary care center where she received radical perineal debridement and aggressive medical and surgical follow-up. Necrotizing fasciitis in a transplant patient is rare; review of the literature shows few cases and no survivors. Our patient has returned to a normal life despite continuation of all immunosuppressive therapy throughout the entire hospital course. In addition, she had a good cosmetic result despite the large necrotic perineal infection. Her survival can be attributed to early diagnosis and referral, immediate and extensive debridement, and aggressive protein replacement.     

The LRINEC (Laboratory Risk Indicator for Necrotizing Fasciitis) score: a tool for distinguishing necrotizing fasciitis from other soft tissue infections

OBJECTIVE: Early operative debridement is a major determinant of outcome in necrotizing fasciitis. However, early recognition is difficult clinically. We aimed to develop a novel diagnostic scoring system for distinguishing necrotizing fasciitis from other soft tissue infections based on laboratory tests routinely performed for the evaluation of severe soft tissue infections: the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score. DESIGN: Retrospective observational study of patients divided into a developmental cohort (n = 314) and validation cohort (n = 140) SETTING: Two teaching tertiary care hospitals. PATIENTS: One hundred forty-five patients with necrotizing fasciitis and 309 patients with severe cellulitis or abscesses admitted to the participating hospitals. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The developmental cohort consisted of 89 consecutive patients admitted for necrotizing fasciitis. Control patients (n = 225) were randomly selected from patients admitted with severe cellulitis or abscesses during the same period. Hematologic and biochemical results done on admission were converted into categorical variables for analysis. Univariate and multivariate logistic regression was used to select significant predictors. Total white cell count, hemoglobin, sodium, glucose, serum creatinine, and C-reactive protein were selected. The LRINEC score was constructed by converting into integer the regression coefficients of independently predictive factors in the multiple logistic regression model for diagnosing necrotizing fasciitis. The cutoff value for the LRINEC score was 6 points with a positive predictive value of 92.0% and negative predictive value of 96.0%. Model performance was very good (Hosmer-Lemeshow statistic, p =.910); area under the receiver operating characteristic curve was 0.980 and 0.976 in the developmental and validation cohorts, respectively. CONCLUSIONS: The LRINEC score is a robust score capable of detecting even clinically early cases of necrotizing fasciitis. The variables used are routinely measured to assess severe soft tissue infections. Patients with a LRINEC score of > or = 6 should be carefully evaluated for the presence of necrotizing fasciitis.     

Necrotizing fasciitis in the pediatric age group: report of a case

Necrotizing fasciitis is a rapidly progressive invasive soft tissue infection that is rarely seen in the pediatric population. In the majority of cases described in the medical literature, there has been an identifiable initiating event such as instrumentation or other trauma to the skin. Because of the rapid progression of the infection, the key to a successful outcome is early recognition and rapid initiation of definitive surgical management. A case is presented in which necrotizing fasciitis was seen in a child with no precipitating skin trauma.     

Sonographic Findings in Necrotizing Fasciitis

Necrotizing fasciitis is a rare but serious disease, and early diagnosis is essential to reducing its substantial morbidity and mortality. The 2 cases presented show that the key clinical and radiographic features of necrotizing fasciitis exist along a continuum of severity at initial presentation; thus, this diagnosis should not be prematurely ruled out in cases that do not show the dramatic features familiar to most clinicians. Although computed tomography and magnetic resonance imaging are considered the most effective imaging modalities, the cases described here illustrate how sonography should be recommended as an initial imaging test to make a rapid diagnosis and initiate therapy.     

Therapies for necrotising fasciitis

Necrotising fasciitis is a rare but life-threatening infectious disease emergency. Delays in diagnosis and treatment are common, and mortality rates often exceed 30%. Successful management of this disease requires high clinical suspicion and aggressive action. The mainstays of therapy include early and wide surgical debridement, antibiotics and supportive care, with prompt surgical intervention. Adjunctive modalities, such as protein synthesis inhibitors, hyperbaric oxygen and intravenous immunoglobulin, may have a role, but their effectiveness remains unproven. New rapid diagnostic tools are emerging that promise to revolutionize early detection of necrotising fasciitis. Research into the molecular microbiology, especially regarding group A streptococcus, are providing novel insights into the pathogenesis of necrotising soft tissue infections and identifying future targets for rationally designed interventions.

Diagnosis of necrotizing fasciitis in children.

Necrotizing fasciitis is a rare but progressive soft tissue infection. This condition is difficult to recognize in the early phase, when it is often confused with cellulitis. We report the cases of four children with necrotizing fasciitis. The initial presentation in these cases was cellulitis. Fever and soft tissue swelling occurred within 24 h and spreading erythema within 4 to 12 h. Radiologic studies of the lesions showed soft tissue thickening. Ultrasonography of the lesions demonstrated distorted, thickened fascia with fluid accumulation. Well-defined, loculated abscesses were demonstrated in two cases. Although typical dusky skin and purplish patches were not found in our cases, necrotizing fasciitis was strongly suspected on the basis of the clinical course and sonographic findings. Ultrasonography also was used as a guide for aspiration of pus. Gram-stained smears and bacterial cultures yielded the pathogens. The choice of antibiotic therapy was made on the results of smears and culture. All patients survived after immediate surgical debridement, intensive antibiotic therapy, and aggressive wound care. In conclusion, ultrasonography provides a rapid and valuable diagnostic modality for necrotizing fasciitis. The pus obtained through sonographically guided aspiration for bacterial culture can allow identification of the pathogenic organisms.

Rapidly advancing necrotizing fasciitis caused by Photobacterium (Vibrio) damsela: a hyperaggressive variant

OBJECTIVE: To describe the first case of Vibrio damsela necrotizing fasciitis in New England, emphasizing the importance of very early operative intervention to achieve source control in this extremely aggressive infection. DESIGN: Case report. SETTING: Surgical intensive care unit at Tufts-New England Medical Center in Boston, MA. PATIENT: A 69-yr-old retired fisherman with rapidly progressive necrotizing fasciitis from Photobacterium (Vibrio) damsela infection and ensuing multiple-system organ failure. INTERVENTIONS: Surgical debridement, ventilator support, vasopressors, continuous veno-venous hemofiltration, and blood product transfusions. MEASUREMENTS AND MAIN RESULTS: Death. CONCLUSIONS: A high index of suspicion is necessary for the diagnosis of this specific pathogen and concordant infection. The willingness to surgically debride and amputate without hesitation at a very early point may be the only intervention capable of saving the lives of patients affected by Photobacterium (Vibrio) damsela.     

The Relationship Between Fluid Accumulation in Ultrasonography and the Diagnosis and Prognosis of Patients with Necrotizing Fasciitis

Necrotizing fasciitis is a severe soft-tissue infection with a high mortality rate. There is little literature on the relationship between the ultrasonographic finding of fluid accumulation along the deep fascia and the diagnosis and prognosis of necrotizing fasciitis. This retrospective study showed that when fluid accumulation was present along the deep fascia, patients with clinically suspected necrotizing fasciitis had a higher probability of having necrotizing fasciitis. The ultrasonographic finding of fluid accumulation with a cutoff point of more than 2 mm of depth had the best accuracy (72.7%) for diagnosing necrotizing fasciitis. In regard to the prognosis of necrotizing fasciitis, when fluid accumulation was present along the deep fascia, patients with necrotizing fasciitis had a longer length of hospital stay and were at risk of amputation or mortality. Ultrasonography is a point-of-care imaging tool that facilitates the diagnosis and prognosis of necrotizing fasciitis.     

Necrotizing fasciitis: a dramatic surgical emergency.

OBJECTIVES: Necrotizing fasciitis is a challenging and potentially lethal disease; early diagnosis is of paramount importance and aggressive multidisciplinary treatment is mandatory. Overall mortality rates of 33-73% have been reported. The aim of this study was to report the experience with necrotizing fasciitis of an emergency surgery department. METHODS: From October 1995 to December 2001 we observed 11 cases of necrotizing fasciitis. The patients were five men and six women, with ages ranging from 33 to 80 years. RESULTS: Triggering aetiological factors were found in eight cases. In all patients a multidisciplinary approach was utilized. Every patient had a daily surgical debridement of the necrotic areas in the operating room. Polyantibiotic therapy was performed, and was changed according to culture results. After surgery, nine patients were submitted to hyperbaric oxygen therapy. Seven deaths (63.6%) were observed: two cases of pulmonary embolism and five cases of septic shock. Four patients survived; three had a complete recovery with progressive healing of the wounds, whereas one patient had severe impairment of the motility of the affected hand. The mean interval between the onset of symptoms and hospital admission was 5.4 days; for patients who ultimately died it was 7.3 days, whereas for patients who ultimately survived it was 2 days (P<0.05); moreover these patients were significantly younger than those who died (P<0.05). CONCLUSION: The treatment for necrotizing fasciitis is a combination of surgical debridement, appropriate antibiotics and optimal oxygenation of the infected tissues. However, the mortality for this disease is quite high, and is related to late diagnosis and advanced age. Necrotizing fasciitis must be considered a true dramatic surgical emergency.     

Necrotizing fasciitis: a challenging diagnosis.

The objective of the study was to evaluate our recent experience in diagnosis and management of necrotizing fasciitis. Records of patients who were diagnosed as having necrotizing fasciitis at Al-Ain Hospital in the period between March 2003 and August 2005 were studied retrospectively with regard to clinical features, risk factors, diagnosis, causative organisms, treatment, and outcome. Eleven patients, eight of whom were men of low socio-economic status, were studied. The median age (range) was 46 (8-65) years. The main risk factor was diabetes mellitus in seven patients (64%). The provisional clinical diagnosis was incorrect in seven patients (64%). Pure beta-hemolytic streptococcus group A or B was the causative organism in five patients (46%). Most of our patients underwent multiple surgical debridements with a median range of two (1-11) operations. Two patients died (overall mortality rate 18%). High clinical suspicion is essential for the diagnosis of necrotizing fasciitis. Accurate early diagnosis, aggressive resuscitation, using proper antibiotics, and extensive surgical debridement are essential for a favorable outcome.     

A case of fatal necrotizing fasciitis after intramuscular administration of diclofenac.

Necrotizing fasciitis is a rapidly progressive soft tissue infection that involves subcutaneous fat and spreads along the fascial planes. This disease has a potentially fatal outcome if not recognized in early. Several cases have been reported of a possible association between the use of non-steroidal anti-inflammatory drugs (NSAIDs) and the development or aggravation of necrotizing fasciitis. This association is still a subject of controversy. In this article we present a case of fatal necrotizing fasciitis occurring in association with intramuscular injections of diclofenac in a patient who was admitted for the symptoms of a urinary stone. Our opinion is that the intramuscular injections caused a locally aseptic necrosis, which was secondarily invaded by. Since this incident, our policy is to avoid the use of intramuscular injections of diclofenac and other NSAIDs in cases of potentially infectious diseases.

Necrotizing fasciitis

Necrotizing fasciitis is a synergistic infection caused by aerobic and anaerobic organisms, resulting in liquefaction and necrosis of the fascia. Clinical findings typically include septicemia, anemia and radiographic evidence of gas in the soft tissue. Most patients have a history of diabetes or atherosclerosis. Morbidity and mortality can be reduced by early diagnosis, extensive surgical debridement and aggressive nutritional support.     

Community-acquired necrotizing fasciitis caused by Acinetobacter calcoaceticus: A case report and literature review

A 61-year-old man presented with pain in the abdomen and right lower limb. He had a history of hepatitis B virus-induced liver cirrhosis, but had not been visiting the outpatient clinic and did not receive any medication. Cutaneous necrosis and bulla were observed on his abdomen and right lower limb. The necrotic skin was incised, and he was diagnosed with necrotizing fasciitis. A nonfermentative Gram-negative bacillus infection was confirmed from aspirated fluid and blood cultures. Therefore, meropenem and immunoglobulins were administered. Because necrosis was widespread, surgical debridement was performed. Thereafter, Acinetobacter calcoaceticus infection was confirmed by semi-quantitative PCR using the bullous fluid and blood cultures. Meropenem was administered for 3 weeks, followed by levofloxacin alone for 1 week. The patient's condition improved; therefore, skin grafting was performed as planned and yielded a favorable response. After rehabilitation, the patient could walk without support and infection did not recur. However, he had severe liver cirrhosis and large esophageal varices, and he eventually died from sudden varix rupture.Necrotizing fasciitis is an uncommon soft tissue infection, associated with high morbidity and mortality, and early recognition and treatment are crucial for survival. Acinetobacter is rarely associated with necrotizing fasciitis. Although this is a very rare case of the occurrence of necrotizing fasciitis due to A. calcoaceticus infection, we believe that this organism can be pathogenic in immunocompromised patients such as those with liver cirrhosis by reporting this case.     

Spontaneous streptococcal gangrenous myositis: survival with early debridement

Spontaneous gangrenous myositis caused by Streptococcus pyogenes is usually fatal, but no longer uniformly so. There appears to be a spectrum of disease due to beta-hemolytic streptococci, from necrotizing fasciitis to pyomyositis to spontaneous gangrenous myositis. Survival is possible with early surgical debridement, reexploration at 24 to 36 hours, and intensive supportive care.     

Ultrasonographic Screening of Clinically-suspected Necrotizing Fasciitis

OBJECTIVE: To determine the accuracy of ultrasonography for the diagnosis of necrotizing fasciitis. METHODS: This study was a prospective observational review of patients with clinically-suspected necrotizing fasciitis presenting to the emergency department of an urban (Taipei) medical center between October 1996 and May 1998. All patients underwent ultrasonographic examination, with the ultrasonographic diagnosis of necrotizing fasciitis based on the criterion of a diffuse thickening of the subcutaneous tissue accompanied by a layer of fluid accumulation more than 4 millimeters in depth along the deep fascial layer, when compared with the contralateral position on the corresponding normal limb. The final diagnosis of necrotizing fasciitis was determined by pathological findings for patients who underwent fasciotomy or biopsy results for patients managed nonoperatively. RESULTS: Data were collected for 62 patients, of whom 17 (27.4%) were considered to suffer from necrotizing fasciitis. Ultrasonography revealed a sensitivity of 88.2%, a specificity of 93.3%, a positive predictive value of 83.3%, a negative predictive value of 95.4%, and an accuracy of 91.9% as regards the diagnosis of necrotizing fasciitis. CONCLUSIONS: Ultrasonography can provide accurate information for emergency physicians for the diagnosis of necrotizing fasciitis.     

A Case of Necrotizing Fasciitis with a LRINEC Score of Zero: Clinical Suspicion Should Trump Scoring Systems

Background

Necrotizing fasciitis (NF) is a potentially lethal infection involving the skin, subcutaneous tissue, and fascia. The Laboratory Risk Indicator for Necrotizing fasciitis (LRINEC) score has been proposed as a way of using abnormal laboratory values to distinguish between severe cellulitis and necrotizing fasciitis.

Objectives

The utility of the LRINEC system, including a review of current literature on this scoring system, is discussed.

Case Report

A case of a 37-year-old man is presented. As part of the diagnostic work-up, appropriate laboratory tests necessary to calculate a LRINEC score were obtained. Despite a LRINEC score of 0, NF was later confirmed at surgery.

Conclusions

Although the LRINEC score has been proposed as a robust way of identifying patients with early NF, it failed to detect NF in the patient reported here. NF should thus remain primarily a disease of clinical suspicion, and this suspicion should trump the LRINEC score.
