Clostridial gas gangrene (CGG) is among the most rapidly spreading infections in humans, with mortality rates approaching 100 % if not treated promptly. Most cases follow traumatic inoculation, although spontaneous infections occur in a minority of patients with immunodeficiency. Spontaneous CGG is primarily caused by Clostridium septicum, whereas traumatic infection is associated with Clostridium perfringens. Patients with CGG present abruptly with rapidly progressive symptoms, underscoring the importance of early recognition, prompt surgical intervention, and appropriate antimicrobial therapy. We describe an illustrative case of spontaneous CGG caused by C. perfringens in a polymorbid 73-year-old female patient. Despite aggressive medical and surgical management, she succumbed to metastatic infection within 48 h of presentation.

Highlights

• Rare case of clostridial gas gangrene involving at least four organs.

• Clostridium perfringens can cause gas gangrene in the absence of traumatic injury.

• NSTIs may present atypically at unsuspecting sites of infection in polymorbid patients.

• Surrogate markers may alert clinicians to NSTI diagnosis before surgical exploration.

• Delayed surgical intervention increases patient morbidity and mortality.

Clostridial gas gangrene (CGG) is a rare but life-threatening infection commonly caused by Clostridium perfringens. Historically, gas gangrene was seen following war wounds, such as the traumatic inoculation of soil-dwelling microorganisms [1]. Spontaneous CGG caused by Clostridium septicum often arises in the setting of immunodeficiency, such as diabetes or malignancy [2].

C. perfringens (formerly Clostridium welchii) is a Gram-positive, spore-forming, rod-shaped, anaerobic bacterium with many virulence factors, including alpha toxin [3]. First isolated in 1891 by William H. Welch, C. perfringens is ubiquitous in nature and has been recovered from soil, aquatic sediments, and the human gastrointestinal tract [4], [5]. It inhabits the genitourinary tract in 1–10 % of healthy women [6].

Approximately 1000 to 3000 cases of CGG are reported annually in the United States; 50 % of these occur after traumatic injuries, 30 % are due to postoperative complications, and 20 % arise spontaneously [4], [7]. The mortality rate of spontaneous CGG has been reported to be 70 to 100 %, typically occurring 2 to 4 days after hospitalization [8].

Diagnosis relies on a physician’s acute clinical awareness of CGG from the patient’s history and physical exam. Patients with necrotizing soft tissue infections (NSTI) may present with fever alongside soft-tissue edema, erythema, and pain [9]. Skin blebs, bullae, or necrosis are also commonly reported [9]. Necrosis of superficial tissues produces a musty fluid with a dishwater appearance [10]. These cardinal signs of infection should prompt immediate surgical debridement and antimicrobial therapy [11]. Untreated, overwhelming infections may result in sepsis, shock, and multisystem organ failure [12].

We report a case of spontaneous CGG caused by C. perfringens in a 73-year-old female patient with gas production in the myocardium, pericardium, cerebral ventricles, gallbladder, biliary tract, and soft tissues. Despite appropriate antibiotic therapy and urgent glenohumeral disarticulation, the patient rapidly decompensated and succumbed to metastatic infection.

Clinical features

A 73-year-old female with a history of end stage renal disease, hypertension, type II diabetes mellitus, heart failure, and atrial fibrillation collapsed following hemodialysis. According to the patient’s caretaker, she developed worsening confusion, agitation, and difficulty remaining upright two days before presentation with a sharp decline after hemodialysis.

On her initial physical exam, she appeared lethargic and toxic appearing, tachycardic, and noted to have right eye deviation with nystagmus. Her tachycardia was noted to be atrial fibrillation with rapid ventricular response. A computed tomography (CT) scan of the head showed a hypodensity in the left temporoparietooccipital region. Initial labs were notable for leukocytosis (36.8 cells x 103/μL), lactic acidosis, and elevated 5th generation high-sensitivity cardiac troponin T (4352 ng/L). Given her significant leukocytosis, she was started on empiric vancomycin, clindamycin, and piperacillin-tazobactam. Due to her altered mental status and suspected ischemic stroke, she was transferred to the neuroscience intensive care unit at an academic medical institution for further care and evaluation.

Upon arrival, she was noted to be hypotensive and in respiratory failure. Her neurologic exam was concerning for a comatose state (did not follow commands, withdraw to pain, or demonstrate purposeful movement). She was immediately intubated for airway protection and placed on vasopressin and norepinephrine for hemodynamic support. Upon further examination, she was noted to have warmth in the right upper extremity with subcutaneous emphysema, concerning for NSTI (Fig. 1). Further laboratory values were notable for leukocytosis (28.5 cells x 103/μL), elevated lactate (6 mmol/L) without acidosis, and elevated C-reactive protein (203.7 mg/L) with anemia (hemoglobin 8.9 g/dL). She also had hypokalemia (3.3 mmol/L), hypoalbuminemia (2.7 g/dL), and hypocalcemia (8.5 mg/dL) with elevated aspartate aminotransferase (148 units/L), alkaline phosphatase (181 units/L), creatinine (4.37 mg/dL), and blood urea nitrogen (57 mg/dL).Fig. 1 Radiographic and clinical images of the patient’s right upper extremity on the night of admission showing erythema, bullae, and subcutaneous emphysema over the forearm and midarm. During glenohumeral disarticulation, surgeons discovered copious dishwater-type fluid and nonviable biceps brachii and brachialis muscles, consistent with clostridial myonecrosis.

Fig. 1

Given her septic shock in the setting of a suspected NSTI, she underwent emergent debridement of her right upper extremity. During the procedure, large amounts of dishwater-type malodorous fluid were noted alongside grey, noncontractile brachialis and biceps brachii muscles. Ischemic tissue and infected fluid extended into the proximal axilla via the neurovascular sheath. Given these findings, the patient underwent glenohumeral disarticulation. Surgical biopsy revealed fibroadipose tissue and skeletal muscle with extensive necrosis and abundant Gram-positive, rod-shaped bacteria.

Blood cultures were collected in aerobic (BacT/Alert FA plus) and anaerobic (BacT/Alert FN plus) blood culture bottles and incubated and monitored using the BacT/Alert Virtuo Microbial Detection System. After three days of incubation, the anerobic bottle signaled positive, and a Gram stain showed Gram-positive rods. Nucleic acid amplification testing (GenMark ePlex BCID-GP Panel) on the positive blood culture bottle did not detect any of the 20 Gram-positive targets on the panel; the pan-Gram negative and pan-Candida targets were also not detected. Anaerobic cultures of the wound were also collected. The specimen was plated to brucella blood agar and a kanamycin-vancomycin/phenylethyl alcohol agar biplate. Plates were incubated anaerobically at 37 °C in a Bactron anaerobic chamber. Both the blood culture and wound culture grew C. perfringens, which was identified using matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry (MS) (VITEK MS, bioMérieux, Inc., Durham, NC). Before these cultures resulted, the patient’s empiric antimicrobial therapy was transitioned to one intravenous dose of cefepime (1 g), metronidazole (500 mg), vancomycin (500 mg), clindamycin (900 mg), and fluconazole (400 mg).

Her troponin increased to 22,407 ng/L and creatine kinase was elevated (1281 units/L). An electrocardiogram showed ST changes with possible left ventricular hypertrophy, concerning for a ST elevation myocardial infarction. Further evaluation with bedside point of care ultrasound as well as radiologically performed echocardiography revealed a severely reduced left ventricular ejection fraction in the range of 20–25 %, mitral valve vegetation concerning for endocarditis, and clot in transit within the inferior vena cava. Given concern for mixed septic and cardiogenic shock, epinephrine was added for additional ionotropic support.

Given her global clinical state, she underwent CT imaging of multiple body regions to determine if source control had been obtained or if there were other areas of infection. A CT scan of the head showed intraparenchymal gas foci in the left temporoparietal region, likely the result of septic emboli. Additionally, new complex appearing air fluid levels were seen in the lateral ventricles, most consistent with pyogenic ventriculitis due to a gas-producing infection (Fig. 2). A chest CT demonstrated gas involving the full thickness of the myocardium at the cardiac apex with extension into the pericardium, consistent with a necrotizing myocardial infection (Fig. 3). Abdomen and pelvis CT showed gas within the lumen and wall of the gallbladder as well as scattered pneumobilia in the left hepatic lobe. These findings were most consistent with emphysematous cholecystitis (Fig. 4).Fig. 2 CT head without contrast demonstrating intraparenchymal gas foci within the left temporoparietal region in area of prior infarct and probable communication with the adjacent left ventricle. Additional complex appearing air fluid levels within the lateral ventricles are most consistent with pyogenic ventriculitis due to a gas forming organism.

Considering the above findings and despite aggressive surgical intervention, it was determined that the infection would have a 100 % mortality and source control would not be attainable due to the extent of inoperable necrotizing infection. Her family elected to proceed with comfort care, and the patient passed away peacefully with family at the bedside. The elapsed time between clinical presentation and demise was less than 48 h. Our patient’s death was reported to the county coroner, who declined to perform an autopsy. Her family was offered but also declined an autopsy.

Discussion

Our patient was a 73-year-old woman who presented with atraumatic CGG following hemodialysis. She developed progressive neurologic symptoms and right upper extremity erythema, edema, and crepitus. On radiographic imaging, she was found to have gas production in the myocardium, pericardium, gallbladder, biliary tract, cerebral ventricles, and subcutaneous tissue. She succumbed to metastatic infection within two days of hospital admission.

This case highlights several atypical features of spontaneous CGG. For example, C. septicum is responsible for most cases of atraumatic CGG and is associated with colonic malignancy and neutropenia [13]. The organism often enters through a defect in the bowel wall due to ischemia, bowel perforation, diverticulitis, or malignancy [13]. However, our patient was infected with C. perfringens, the most common cause of CGG related to penetrating trauma or crush injuries [8]. Without known antecedent injury, febrile neutropenia, or gastrointestinal barrier disruption, this patient had a dubious route of infection.

Reviewing the literature, we found 13 cases of spontaneous CGG secondary to C. perfringens (Table 1) [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25]. All but two patients had known risk factors, including atherosclerosis, diabetes, immunosuppression, or malignancy. All patients < 50 years had an underlying hematologic malignancy, while patients > 50 years had various cardiovascular, metabolic, and neoplastic comorbidities. C. perfringens was isolated from blood, muscle, or wound cultures in every patient. Most patients underwent surgical intervention (77 %) and antibiotic treatment (92 %), although antibiotic selection varied markedly. Excluding our case, we calculated a mortality rate of 85 %.Table 1 Clinical and microbiological characteristics of patients with spontaneous or atraumatic gas gangrene secondary to Clostridium perfringens.

Literature on multiorgan CGG is sparse, although several case reports have detailed multiorgan infections following liver transplantation and C. septicum bacteremia [26], [27]. Separate reports describing isolated gas production in the brain and heart have also been published [28], [29]. However, cases of disseminated infection with documented gas production in four or more organs were not discovered in our literature review.

Spontaneous CGG may present atypically in immunocompromised states, such as neutropenia, colon cancer, leukemia, and diabetes [2]. As seen in this case, spontaneous CGG may also present with anaerobic bacteremia, a rarity among bloodstream infections as anaerobes are responsible for 1–17 % of positive blood cultures [30]. In patients with mysterious infections, an autopsy may help clarify the disease course [28].

Early diagnosis with timely surgical intervention and appropriate antibiotic management reduces the morbidity and mortality of NSTI. Surrogate laboratory markers for the early diagnosis of infections with significant disfigurement and mortality are valuable and should be further researched. For example, the Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) score is an objective scoring system based on six laboratory values – white blood cells, hemoglobin, C-reactive protein, sodium, creatinine, and glucose – that distinguishes necrotizing fasciitis from cellulitis, abscesses, and other skin and soft tissue infections [31], [32]. Scored out of 13 points, patients with scores ≥ 6 or ≥ 8 have positive predictive values of 92 % and 93.4 %, respectively [32]. When used in appropriate settings, surrogate markers may alert clinicians to the possibility of NSTI prior to surgical exploration.

Prompt surgical exploration and source control are the most important components of NSTI therapy because antibiotics are unable to penetrate necrotic tissue. Surgical exploration facilitates specimen collection for microbiology and pathology and may result in debridement or amputation [8]. Given the rapid progression of NSTI, diagnostic imaging should not delay surgical intervention [1]. In fact, two studies found that inadequate, delayed (>24 h after admission), or lack of surgical debridement was linked to 7.5-fold and 9.4-fold increases in mortality, respectively [33], [34]. Standardizing and validating the definition of “early” surgical intervention, proposed by some as <6 h following diagnosis or admission, may further refine NSTI treatment algorithms and improve hospital outcomes [35], [36].

With few clinicians ordering and fewer labs performing susceptibility testing for anaerobic organisms, antibiotic recommendations for CGG are based on multicenter surveys and literature reviews [37]. Most Clostridium spp., including C. perfringens, are susceptible to penicillin and ampicillin, although resistance has been reported [38]. Definitive CGG is currently treated with penicillin and clindamycin for 10–14 days [39], [40]. Experimental studies have shown that combination therapy with clindamycin and penicillin or monotherapy with clindamycin or metronidazole treated fulminant CGG in murine models efficaciously [41], [42]. Without knowing the causative agent, NSTI is treated empirically with vancomycin plus piperacillin-tazobactam, ampicillin-sulbactam, or a carbapenem [40].

Conclusion

CGG is a rare but life-threatening infection often incited by traumatic injury, although spontaneous cases occur secondarily in immunocompromised patients. Given its rapid progression and high mortality rate, physicians should maintain a high index of suspicion for CGG in patients presenting with soft tissue discoloration, crepitus, or blisters containing dishwater fluid. Prompt diagnosis, surgical debridement, and intravenous antibiotics are necessary to prevent amputation or death. Our patient illustrates how CGG may present atypically at unsuspecting sites of infection in immunocompromised and polymorbid patients. A computerized literature review found no similar cases.
