Fulminant necrotising fasciitis developing during long term corticosteroid treatment of systemic lupus erythematosus

Necrotising fasciitis in systemic lupus erythematosus: a case report and literature review

Necrotising fasciitis (NF) is a rare infection of the subcutaneous tissue, known to be rapidly progressive and potentially fatal. Patients with systemic lupus erythematosus (SLE) may be predisposed to this condition, and early clinical recognition can be difficult. We report a case of necrotising fasciitis in a 26-year-old woman with SLE. She presented with painful swelling of her left leg, then developed clinical features of septic shock. Emergency debridement was performed. Intraoperative findings revealed NF and cultures grew Pseudomonas aeruginosa. The patient survived after a lengthy hospital admission, following several further debridements complicated by recurrent chest sepsis and multiorgan failure. We also review and discuss the published cases of NF in SLE patients.

Necrotizing fasciitis--a diagnostic dilemma: two case reports

Introduction

Necrotizing soft tissue infections can affect various tissue planes. Although predisposing etiologies are many, they mostly center on impaired immunity occurring directly or indirectly and loss of integrity of protective barriers which predispose to infection. The nonspecific presentation may delay diagnosis and favor high mortality.

Case presentation

Two case vignettes are presented. The first patient, a 44-year-old healthy South Asian man with a history of repeated minor traumatic injury presented to a primary health care center with a swollen left lower limb. He was treated with antibiotics with an initial diagnosis of cellulitis. Because he deteriorated rapidly and additionally developed intestinal obstruction, he was transferred to our hospital which is a tertiary health care center for further evaluation and management. Prompt clinical diagnosis of necrotizing soft tissue infection was made and confirmed on magnetic resonance imaging as necrotizing fasciitis. Urgent debridement was done, but the already spread infection resulted in rapid clinical deterioration with resultant mortality. The second patient was a 35-year-old South Asian woman with systemic lupus erythematous receiving immunosuppressive therapy who developed left lower limb pain and fever. Medical attention was sought late as she came to the hospital after 4 days. Her condition deteriorated rapidly as she developed septic shock and died within 2 days.

Conclusions

Necrotizing fasciitis can be fatal when not recognized and without early intervention. Clinicians and surgeons alike should have a greater level of suspicion and appreciation for this uncommon yet lethal infection.

[Periorbital necrotizing fasciitis: a complication of a dacryocystorhinostomy]

We report a rare case of periorbital necrotizing fasciitis following a dacryocystorhinostomy procedure. We describe the common features of this rare infection of the skin and subcutaneous tissues and discuss the different management strategies as well as the controversial role of anti-inflammatory medication in treating this condition.

Fulminant necrotizing fasciitis following the use of herbal concoction: a case report

Introduction

Necrotizing fasciitis is a rare and life-threatening rapidly progressive soft tissue infection. A fulminant case could involve muscle and bone. Necrotizing fasciitis after corticosteroid therapy and intramuscular injection of non-steroidal anti-inflammatory drugs has been reported. We present a case of fulminant necrotizing fasciitis occurring in a patient who used a herbal concoction to treat a chronic leg ulcer.

Case presentation

A 20-year-old Ibo woman from Nigeria presented with a three-year history of recurrent chronic ulcer of the right leg. She started applying a herbal concoction to dress the wound two weeks prior to presentation. This resulted in rapidly progressive soft tissue necrosis that spread from the soft tissue to the bone, despite aggressive emergency debridement. As a result she underwent above-knee amputation.

Conclusion

The herbal concoction used is toxic, and can initiate and exacerbate necrotizing fasciitis. Its use for wound dressing should be discouraged.

Late diagnosed necrotizing fasciitis as a cause of multiorgan dysfunction syndrome: A case report

Necrotizing fasciitis is a rapidly progressive, life-threatening soft tissue bacterial infection. We present a serious case of a 43-year-old male who suffered from necrotizing fasciitis of the left leg in whom a delayed diagnosis caused multiorgan dysfunction.

Early recognition of important symptoms is essential in the management and surgical debridement of necrotizing fasciitis. Treatment should include comprehensive supportive measures (early goal-directed therapy, adequate ventilation strategy, activated protein C dosage, tight glucose control, steroids, renal replacement therapy) and early antibiotic therapy based on microbiologic monitoring. The pathophysiology and etiologic factors of necrotizing fasciitis are discussed.

Necrotizing Fasciitis in Systemic Lupus Erythematosus

OBJECTIVES

Necrotizing fasciitis (NF) is an uncommon infection of the subcutaneous tissue and superficial fascia. Any delay in treatment can lead to catastrophic results with high mortality. It is well known that patients with systemic lupus erythematosus (SLE) are at increased risk of infection, from the disease and/or its treatment. The objective of our study was to evaluate the presenting features of NF in SLE patients and to identify possible risk factors for this severe complication.

METHODS

We searched for patients with diagnoses of SLE and NF using a computerized patient database at Montefiore Medical Center (MMC), from 1996 to present. We also included patients from the MMC Lupus Clinic with these diagnoses (identified from paper records) from 1994 to present. Of a total of 449 patients with SLE that were followed during this time, 8 patients with NF were identified, and their records were reviewed.

RESULTS

Two of the 8 patients (25%) died during hospitalization. A third patient died within 2 months of hospital discharge. All 8 patients were receiving steroids at the time of diagnosis, and 7 of 8 had hypoalbuminemia and lymphopenia. Both patients who died in the hospital and the one patient who died within 2 months of her discharge had lupus nephritis.

CONCLUSIONS

NF is an uncommon infection, but one that must be recognized early if the outcome is to be favorable. This series of 8 cases of NF in SLE from a single institution suggests that heightened awareness is warranted, particularly among SLE patients who are immunosuppressed by virtue of their underlying disease, the therapy they require, or both.

Severe necrotizing fasciitis in a human immunodeficiency virus-positive patient caused by methicillin-resistant Staphylococcus aureus

Methicillin-resistant Staphylococcus aureus (MRSA) is a rarely reported cause of necrotizing fasciitis. We report an unusually severe case of MRSA necrotizing fasciitis in a previously undiagnosed AIDS patient. Molecular analysis revealed that the strain had the USA300/spa1 genotype, now an abundant cause of community-acquired MRSA infection.

Necrotizing fasciitis resulting from Streptococcus pneumoniae in recently diagnosed systemic lupus erythematosus case: a case report

Systemic lupus erythematosus (SLE) is a systemic, autoimmune disease. SLE patients are prone to infections, and their hospital admissions and mortality are most commonly associated with infections. Necrotizing fasciitis (NF) is a rare, life-threatening infection of the subcutaneous tissue. In this report, NF associated with Streptococcus pneumoniae (SPN) that developed within hours and resulted in death is presented in a 46-year-old female case who was recently diagnosed as SLE and did not receive any medication (steroid, immunosuppressive, etc.) except for etodolac. This case shows that SLE can generate predisposition to NF, and SPN can play a role in NF etiology.
