ABSTRACT

Background: Lack of insurance is associated with poorer outcomes in hospitalized patients. However, few studies have explored this association in hospitalizations for necrotizing soft tissue infections (NSTIs). This study examined the impact of insurance status on the outcome of NSTI admissions. Methods: All adult hospitalizations for necrotizing fasciitis, gas gangrene, and Fournier gangrene between 2016 and 2018 were examined using the Nationwide Inpatient Sample database. Insurance status was categorized as insured (including Medicare, Medicaid, and Private, including Health maintenance organization (HMO) or uninsured (Self-pay). Outcome measures included mortality rates, limb loss, length of hospital stay, prolonged hospital stay, and critical care admissions. Statistical analysis included weighted sample analysis, chi-square tests, multivariate regression analysis, and negative binomial regression modeling. Results: Approximately 29,705 adult hospitalizations for NSTIs were analyzed. Of these, 57.4% (17,065) were due to necrotizing fasciitis, 22% (6,545) to gas gangrene, and 20.5% (6,095) to Fournier gangrene. Approximately 9.7% (2,875) were uninsured, whereas 70% (26,780) had insurance coverage. Among the insured, Medicare covered 39.6% (10,605), Medicaid 29% (7,775), and private insurance 31.4% (8,400). After adjustments, Medicare insurance was associated with greater odds of mortality (adjusted odds ratio [aOR]: 1.81; 95% confidence interval [CI]: 1.33-2.47; p = 0.001). Medicaid insurance was associated with increased odds of amputation (aOR: 1.81; 95% CI: 1.33-2.47; p < 0.001), whereas private insurance was associated with lower odds of amputation (aOR: 0.70; 95% CI: 0.51-0.97; p = 0.030). Medicaid insurance was associated with greater odds of prolonged hospital stay (aOR: 1.34; 95% CI: 1.09-1.64; p < 0.001). No significant association was observed between the lack of insurance or self-pay and the odds of primary or secondary outcomes. Conclusion: Medicare insurance was correlated with greater odds of mortality, whereas Medicaid insurance was associated with increased odds of amputation and longer hospital stay. Uninsured status was not associated with significant differences in NSTI outcomes.

ABSTRACT

Gas gangrene is a lethal necrotic infection resulting in gas production within tissue. It is typically associated with trauma and is especially lethal during pregnancy, resulting in severe maternal infection and fetal death. We report the case of a 31-year-old G3P2 female who presented to the emergency department with abdominal bloating, vaginal cramping, and brown vaginal discharge. Physical examination showed that the patient was hypertensive, tachycardic, and tachypneic, and laboratory examination showed a downtrending beta-human chorionic gonadotropin and leukocytosis, with elevated inflammatory markers. Ultrasound showed copious gas located within the lower abdomen and the fetus was not visualized. Computed tomography (CT) of the abdomen and pelvis showed a gravid uterus with a single fetus and extensive air locules in the fetus, amniotic cavity, and placenta. The findings were consistent with gas gangrene of a mature fetus in the third trimester. Fetal gas gangrene is a potentially lethal condition during pregnancy, and early diagnosis is imperative in management. CT was utilized in this case to outline the increased gas production within the amniotic cavity and fetal organs and proved crucial in determining the next steps of management.

ABSTRACT

Absent in melanoma 2 (AIM2), a key component of the IFI20X/IFI16 (PYHIN) protein family, is characterized as a DNA sensor to detect cytosolic bacteria and DNA viruses. However, little is known about its immunological role during pathogenic Clostridium perfringens (C. perfringens) infection, an extracellular bacterial pathogen. In a pathogenic C. perfringens gas gangrene model, Aim2-/- mice are more susceptible to pathogenic C. perfringens soft tissue infection, revealing the importance of AIM2 in host protection. Notably, Aim2 deficiency leads to a defect in bacterial killing and clearance. Our in vivo and in vitro findings further establish that inflammasome signaling is impaired in the absence of Aim2 in response to pathogenic C. perfringens. Mechanistically, inflammasome signaling downstream of active AIM2 promotes pathogen control. Importantly, pathogenic C. perfringens-derived genomic DNA triggers inflammasome signaling activation in an AIM2-dependent manner. Thus, these observations uncover a central role for AIM2 in host defense and triggering innate immunity to combat pathogenic C. perfringens infections.

ABSTRACT

AIM: Gas gangrene (GG) is a rare severe infection with a very high mortality rate mainly caused by Clostridium species. It develops suddenly, often as a complication of abdominal surgery or liver transplantation. We report a case of GG of the liver occurred after percutaneous microwave (MW) ablation of an hepatocellular carcinoma (HCC) successfully treated with percutaneous Radiofrequency ablation (RFA). CASE PRESENTATION: A 76-year-old female patient was treated with MW ablation for a large HCC in the VIII segment; 2 days later she developed fever, weakness, abdominal swelling and was hospitalized with diagnosis of anaerobic liver abscess. Despite antibiotic therapy, the patient conditions worsened, and she was moved to the intensive care unit (ICU). Percutaneous drainage was attempted, but was unsuccessful. The surgeon and the anesthesiologist excluded any indication of surgical resection. We performed RFA of the GG by 3 cool-tip needles into the infected area. The procedure was well tolerated by the patient, who left the hospital for follow-up. CONCLUSION: Percutaneous RFA could be a valuable therapy of focal GG of the liver in patients refractory to antibiotics and when surgery and OLT are not feasible. A fast and early indication is needed in case of rapid worsening of the patient's conditions.

ABSTRACT

A transtibial amputation is the traditional primary staged amputation for source control in the setting of non-salvageable lower extremity infection, trauma, or avascularity prior to progression to proximal amputation. The primary aim of the study is to compare preoperative risk factors and postoperative outcomes between patients who underwent transtibial amputation versus ankle disarticulation in staged amputations. A retrospective review of 152 patients that underwent staged below the knee amputation were compared between those that primarily underwent transtibial amputation (N = 70) versus ankle disarticulation (N = 82). The mean follow-up for all 152 patients was 2.1 years (range = 0.04-7.9 years). The odds of incisional healing were 3.2 times higher for patients with guillotine amputation compared to patients with ankle disarticulation (odds ratio [OR] = 3.2, 95% confidence interval [CI] = 1.437-7.057). The odds of postoperative infection is 7.4 times higher with ankle disarticulation compared to patients with guillotine amputation (OR = 7.345, 95% CI = 1.505-35.834). There were improved outcomes in patients that underwent staged below the knee amputation with primarily guillotine transtibial amputation compared to primarily ankle disarticulation. Ankle disarticulation should be reserved for more distal infections, to allow for adequate infectious control, in the aims of decreasing postoperative infection and improving incisional healing rates.Levels of Evidence: 3, Retrospective study.

ABSTRACT

Splenic gas gangrene caused by Clostridium perfringens is rare. A 73-year-old woman was referred to our hospital because of fatigue, dyspnea, and left hypochondrial pain. She had a history of blunt trauma to the left abdomen eight days ago. She presented with hypoxemia and a high inflammatory response on blood tests. A CT showed left pleural effusion and gas in the spleen. She was treated with antimicrobials and underwent splenectomy. C. perfringens was identified from blood and intraoperative ascites cultures. She recovered and was discharged on day 34 of hospitalization. As C. perfringens is part of the normal gut microbiota and can translocate to other parts of the body, this bacterium should be considered a splenic abscess pathogen when an intracorporeal anaerobic environment is suspected.

ABSTRACT

A patient presented with fever, severe pain and edematous tight due to hip trauma and was scheduled for urgent fasciotomy. Following physical examination, laboratory analyses were requested, and results revealed anemia and severe infection. As the patient's condition was serious, a new set of samples was sent to the laboratory four hours later. Following centrifugation, severely hemolyzed dark-colored serum and plasma samples were obtained and in vitro hemolysis was suspected. The collection of samples was repeated, but a new set of samples was also hemolyzed with a significant decrease in the hemoglobin value. At that point, in vivo hemolysis was suspected, and samples were processed according to standard laboratory procedures for hemolytic samples. Following confirmation of the gas gangrene diagnosis by clinicians, the cause of hemolysis was attributed to the cytotoxic activity of α-toxin produced by the anaerobic gram-positive bacterium Clostridium perfringens. An insight into the laboratory procedure that could help to narrow down the causes of hemolysis and single out C. perfringens as a cause of intravascular hemolysis was given.

ABSTRACT

Gas gangrene is a rare, severe gas-producing infection that can be related to colorectal cancer. Gas gangrene can be confirmed by radiologic findings and crepitation on touch. Spontaneous gas gangrene can be associated with colorectal cancer. An 80-year-old female complaint about a sudden abdominal pain, accompanied with progressive swelling pain in thigh and fever. Diagnosis based on assessment findings were gas gangrene and descending colonic cancer perforation. Emergency surgery was performed for debridement and drainage, followed by vacuum sealing drainage (VSD) with polyurethane (PU). Two more surgical interventions were given before the colonic tumor surgery. The patient recovered well in the long-term follow-up. This report demonstrates the diagnosis, treatment, and management of a successful case of gas gangrene caused by perforation of descending colonic cancer. Accurate preoperative diagnosis and reasonable use of VSD (PU) material played an important role in the treatment of this case.

ABSTRACT

Introduction: There are inconsistencies in outcome reporting for patients with necrotising soft tissue infections (NSTI). The aim of this study was to evaluate reported outcome measures in NSTI literature that could inform a core outcome set (COS) such as could be used in a study of hyperbaric oxygen in this indication. Methods: A systematic review of all NSTI literature identified from Cochrane, Ovid MEDLINE and Scopus databases as well as grey literature sources OpenGrey and the New York Academy of Medicine databases which met inclusion criteria and were published between 2010 and 2020 was performed. Studies were included if they reported on > 5 cases and presented clinical endpoints, patient related outcomes, or resource utilisation in NSTI patients. Studies did not have to include intervention. Two independent researchers then extracted reported outcome measures. Similar outcomes were grouped and classified into domains to produce a structured inventory. An attempt was made to identify trends in outcome measures over time and by study design. Results: Three hundred and seventy-five studies were identified and included a total of 311 outcome measures. Forty eight percent (150/311) of outcome measures were reported by two or more studies. The four most frequently reported outcome measures were mortality without time specified, length of hospital stay, amputation performed, and number of debridements, reported in 298 (79.5%), 260 (69.3%), 156 (41.6%) and 151 (40.3%) studies respectively. Mortality outcomes were reported in 23 different ways. Randomised controlled trials (RCTs) were more likely to report 28-day mortality or 90-day mortality. The second most frequent amputation related outcome was level of amputation, reported in 7.5% (28/375) of studies. The most commonly reported patient-centred outcome was the SF-36 which was reported in 1.6% (6/375) of all studies and in 2/10 RCTs. Conclusions: There was wide variance in outcome measures in NSTI studies, further highlighting the need for a COS.

ABSTRACT

IMPORTANCE: Clostridium perfringens causes gas gangrene and food poisoning in humans, and monitoring this bacterium is important for public health. Although whole-genome sequencing is useful to comprehensively understand the virulence, resistome, and global genetic relatedness of bacteria, limited genomic data from environmental sources and developing countries hamper our understanding of the richness of the intrinsic genomic diversity of this pathogen. Here, we successfully accumulated the genetic data on C. perfringens strains isolated from hospital effluent and provided the first evidence that predicted pathogenic C. perfringens may be disseminated in the clinical environment in Ghana. Our findings suggest the importance of risk assessment in the environment as well as the clinical setting to mitigate the potential outbreak of C. perfringens food poisoning in Ghana.

ABSTRACT

Clostridium perfringens, a Gram-positive anaerobic bacterium, is well-known for its association with gas gangrene, a severe and rapidly progressing infection characterized by tissue gas production and necrosis. In this case report, we present the instance of a 64-year-old male with poorly controlled diabetes mellitus who developed a C. perfringens-related infection following a traumatic foot wound. The report emphasizes the critical significance of early diagnosis and aggressive treatment in C. perfringens infections, particularly in patients with underlying risk factors. Detailed accounts of clinical findings, laboratory results, computed tomography, and surgical interventions are provided. A multidisciplinary approach proved essential for successful management. The inherent scholarly value of this case is substantiated by its meticulous documentation of the clinical trajectory, diagnostic modalities, and treatment modalities employed. The intricate collaboration across diverse medical disciplines, the uncommon manifestation of the infection following a traumatic foot wound, and the favorable outcome achieved through prompt and multidisciplinary intervention collectively contribute to the exceptional nature and didactic significance of this case. The dissemination of such clinical experiences assumes paramount importance in advancing medical scholarship, cultivating awareness, and engendering a profound comprehension of the complexities associated with C. perfringens infections, thereby enriching the wider scientific and medical community.

ABSTRACT

Neutrophil extracellular traps (NETs) are networks of DNA and various microbicidal proteins released to kill invading microorganisms and prevent their dissemination. However, a NETs excess is detrimental to the host and involved in the pathogenesis of various inflammatory and immunothrombotic diseases. Clostridium perfringens is a widely distributed pathogen associated with several animal and human diseases, that produces many exotoxins, including the phospholipase C (CpPLC), the main virulence factor in gas gangrene. During this disease, CpPLC generates the formation of neutrophil/platelet aggregates within the vasculature, favoring an anaerobic environment for C. perfringens growth. This work demonstrates that CpPLC induces NETosis in human neutrophils. Antibodies against CpPLC completely abrogate the NETosis-inducing activity of recombinant CpPLC and C. perfringens secretome. CpPLC induces suicidal NETosis through a mechanism that requires calcium release from inositol trisphosphate receptor (IP3) sensitive stores, activation of protein kinase C (PKC), and the mitogen-activated protein kinase/extracellular signal-regulated kinase (MEK/ERK) pathways, as well as the production of reactive oxygen species (ROS) by the metabolism of arachidonic acid. Proteomic analysis of the C. perfringens secretome identified 40 proteins, including a DNAse and two 5´-nucleotidases homologous to virulence factors that could be relevant in evading NETs. We suggested that in gas gangrene this pathogen benefits from having access to the metabolic resources of the tissue injured by a dysregulated intravascular NETosis and then escapes and spreads to deeper tissues. Understanding the role of NETs in gas gangrene could help develop novel therapeutic strategies to reduce mortality, improve muscle regeneration, and prevent deleterious patient outcomes.

ABSTRACT

This paper presents treatment strategies for orbital necrotizing fasciitis (NF) in a case of a 33-year-old male diagnosed with orbital NF, which developed after dental root canal treatment. Although orbital NF is rare, it is rapidly progressive and can easily lead to the loss of tissue and visual function, sometimes to a life-threatening extent. Prompt and adequate treatment has been a challenge yet remains quite essential. In addition to the conventional approach to NF, such as immediate antibiotic administration and drainage, orbital NF patients like this case were often treated by incorporating additional steps, which include: 1) performing minimally invasive but adequate removal of necrotic tissue through intraoperative use of ultrasound equipment and postoperative use of proteolytic enzyme-containing ointment for chemical debridement; 2) managing intraorbital pressure by lateral cantholysis and orbital floor removal (decompression); and 3) maintaining the aerobic conditions of the wound after surgical drainage via orbital wall removal. Thus far, satisfactory results in patients with extensive NF of the orbit, including the presented case, were achieved with regards to preserving periorbital tissues, vision, and ocular motility through a multidisciplinary approach. These should be considered as optional means of preserving the orbital tissue and visual function.

ABSTRACT

Clostridium perfringens (C. perfringens) is an important Gram-positive anaerobic spore-forming pathogen that provokes life-threatening gas gangrene and acute enterotoxaemia, although it colonizes as a component of the symbiotic bacteria in humans and animals. However, the mechanisms by which C. perfringens is cleared from the host remains poorly understood, thereby impeding the development of novel strategies for control this infection. Here, we uncover a beneficial effect of extracellular traps (ETs) formation on bacterial killing and clearance by phagocytes. C. perfringens strain ATCC13124, and wild-type isolates CP1 and CP3 markedly trigger ETs formation in macrophages and neutrophils. As expected, visualization of DNA decorated with histone, myeloperoxidase (MPO) and neutrophils elastase (NE) in C. perfringens-triggered classical ETs structures. Notably, the bacteria-induced ETs formation is an ERK1/2-, P38 MAPK-, store-operated calcium entry (SOCE)-, NADPH oxidase-, histone-, NE-, and MPO-dependent process, and is independent of LDH activity. Meanwhile, the defect of bactericidal activity is mediated by impairing ETs formation in phagocytes. Moreover, In vivo studies indicated that degradation of ETs by DNase I administration leads to a defect in the protection against experimental gas gangrene, with higher mortality rates, exacerbated tissue damage, and more bacterial colonization. Together, these results suggest that phagocyte ETs formation is essential for the host defense against C. perfringens infection.

ABSTRACT

BACKGROUND: Necrotizing fasciitis in neonates is a rare and life-threatening infection involving necrosis of the skin, subcutaneous tissues, deep fascia, and sometimes underlying muscles, with a fulminant course and high mortality rate. Necrotizing fasciitis with gas gangrene related to infection of a peripherally inserted central catheter is very rare. CASE PRESENTATION: The patient was a full-term female neonate born by vaginal delivery. Following diagnosis of patent ductus arteriosus, indomethacin was administered from a peripherally inserted central catheter for 3 days. Four days after the termination of medical treatment for the patent ductus arteriosus, the patient developed fever and a severely elevated inflammatory response was identified from blood testing. Around the right anterior chest wall, corresponding to the site of the catheter tip, redness was increased and gas crepitus was felt under the skin. Computed tomography revealed emphysema in the anterior chest, in subcutaneous areas and between muscles. Emergency surgical debridement was performed under a diagnosis of necrotizing fasciitis with gas gangrene. With antibiotic treatment, we started to fill the wound with a dialkyl carbamoyl chloride-coated dressing and povidone-iodine sugar ointment after washing with saline once a day. The patient survived and after 3 weeks of treatment with the dressing, the wound had successfully resolved without motor impairments. CONCLUSIONS: In addition to medical treatment and prompt surgical debridement, we used dialkyl carbamoyl chloride-coated dressing and povidone-iodine sugar ointment for antiseptic dressings and successfully treated neonatal necrotizing fasciitis with gas gangrene caused by peripherally inserted central catheter infection with Citrobacter koseri.

ABSTRACT

INTRODUCTION AND IMPORTANCE: Clostridial myonecrosis (CM), or gas gangrene, is a rare necrotizing muscle infection caused most often by Clostridium perfringens or C. septicum. Inoculation can occur either traumatically or spontaneously. CM has a high mortality rate if not treated promptly. CASE PRESENTATION: A 64-year-old male presented to the emergency department (ED) with sudden onset left flank pain and fever. Repeated CT scans demonstrated progressive edema around the left iliopsoas muscle with gas formation and bleeding. The patient received intravenous fluids, meropenem, and clindamycin. Emergency laparotomy was performed on suspicion of necrotizing fasciitis and revealed a necrotic left iliopsoas muscle which was partially excised. Blood cultures were positive at 12 h with growth of C. septicum. Prolonged stay in the intensive care unit, and six additional surgical interventions to the abdomen, left thigh, and flank were needed. The patient was discharged after four months to a nursing home. CLINICAL DISCUSSION: C. septicum CM more often occurs spontaneously and is associated with colorectal malignancy. However, for our patient, CT colonography and proctoscopy did not reveal any pathology. Therefore, we believe the CM resulted from an injury the patient sustained while working in his backyard, either a cut from barbed wire on his arm or from soil contaminating his psoriatic lesions. Successful outcomes for patients with CM require a high index of suspicion, timely treatment with antibiotics, and repeated surgical debridements. CONCLUSION: This case report describes the presentation and management of a presumably injury-related CM caused by C. septicum.

ABSTRACT

Clostridium perfringens (C. perfringens) and Klebsiella oxytoca (K. oxytoca) are pathogenic human bacteria. Clostridium perfringens sepsis with intravascular hemolysis is a catastrophic process with an extremely high mortality rate (70 to 100%). A 74-year-old male submitted to an elective laparoscopic cholecystectomy due to cholelithiasis and develops severe abdominal pain only 10 hours after being discharged from hospital. He was admitted to the emergency department with associated jaundice, fever, and hematuria. On arrival, his hemoglobin level was 9.2 g/dL but fell to 3.4g/dL within two hours. Massive intravascular hemolysis was diagnosed and a liver abscess with gas gangrene was shown in the contrast-enhanced computed tomographic. Despite proper management, a fatal outcome was unavoidable and the patient died eight ours later. Microbiological examination isolated C. perfringens and K. oxytoca. Liver abscesses caused by C. perfringens and K. oxytoca are extremely rare complications of laparoscopic cholecystectomy. Early recognition and prompt antibiotic therapy as well as control of septic focus are essential to minimize this fatal outcome.

ABSTRACT

Background: Clostridium perfringens is a well-known cause of gas gangrene with a very high mortality rate. Multiple cases of internal organs have been reported in the literature; however, non-traumatic spontaneous gas gangrene due to C. perfringens with solely cardiac involvement in a patient without any risk factors has not been reported before. Case Summary: A 52-year-old male presented to the emergency department with chest pain and exertional dyspnoea for three days. The patient was haemodynamically stable initially, and the physical examination was unremarkable. Initial laboratory workup revealed elevated D-dimer and troponin levels. Computerized tomography (CT) of the chest was negative for pulmonary embolism but showed a hypodense focus in the cardiac silhouette. Acute coronary syndrome protocol was initiated; however, invasive cardiac workup was negative. The patient had rapid clinical deterioration with development of respiratory failure, shock, and multiorgan failure within 24 h. A transesophageal echocardiogram demonstrated an abnormal echogenic focus, corresponding to CT chest area. Despite aggressive treatment, the patient passed away within 36 h. Later, the patient's blood culture grew C. perfringens. A limited autopsy showed an abscess cavity in the interventricular septum, pathology of which revealed acute myocarditis and fibrinous pericarditis. Discussion: Unlike other reported cases of C. perfringens with cardiac abscess, our patient had no known risk factors, and no other organs were involved. We conclude from this case that an air focus on the CT scan in the myocardium can be suggestive of a spontaneous gas gangrene of the myocardium, and the patients should be treated accordingly.
