A life saving case of Vibrio vulnificus (septic type)]

After eating raw shellfish, 62-year-old man suffered from watery diarrhea and leg pain. The disease developed to septicemia and necrotizing fasciitis of bilateral lower extremities. Vibrio vulnificus was isolated from wound. He was treated with antibiotics, surgical debridement and hyperbaric oxygen therapy, and consequently was saved. Effect of hyperbaric oxygen therapy on V. vulnificus infection was discussed.     

Shewanella infection in decompensated liver disease: a septic case

Shewanella species are an unusual cause of disease in humans. However, reports of Shewanella infections have been increasing, and hepatobiliary disease has been proposed as a predisposing factor following a critical course. We report the first Japanese septic case of decompensated liver disease in which this bacterium acted as a definite pathogen. A 67-year-old Japanese man with primary sclerosing cholangitis was admitted to our hospital complaining of fever, general fatigue, pain, and a rash on the lower left extremity. He was tentatively diagnosed with necrotizing fasciitis caused by Vibrio vulnificus because of his decompensated cirrhotic liver and history of consuming raw fish. Thereafter, the diagnosis was altered to cellulitis and Shewanella septicemia on the basis of the characteristics of his skin lesion and an arterial blood culture. He died of multiple organ failure on the eleventh day in the hospital. Since several reports have demonstrated that Shewanella can cause lethal sepsis in patients with hepatobiliary disease, we should be aware of the pathogenicity of this bacterium.     

Severe sepsis with organ failure in necrotizing fasciitis of the right leg caused by infection with Vibrio vulnificus

Vibrio vulnificus is a human pathogen which can cause the septicemia and necrosis of the soft tissue, especially fasciitis. The occurrence is most common in the summer, the source of infection can be sea water or the sand on the beaches, however the infection after eating seafood was described as well. The patient with predominant liver dysfunction are more often affected. The clinical course is characterized by severe sepsis, and massive skin lesion. The mortality more than 60% is reported. This case report describes the course of disease in 64 year old patient, who has spent his vacation in Bulgaria. After return he was admitted with severe sepsis with multiorgan failure and despite the intensive therapy and high amputation of the limb which was performed, the patient died.     

An autopsied case of septicemia due to Vibrio vulnificus

A 63-year-old male with liver cirrhosis due to type-C hepatitis virus was admitted on June 14, 1999 to our hospital with complaints of dyspnea, and blisters, swelling and purpuras on his legs. He had consumed raw fish one or two days before. He was already in a state of shock with sepsis and disseminated intravascular coagulation shortly after the admission. Although treatment with MEPM and MINO for sepsis, and daltepalin sodium, antithrombin III and gabexate mesilate for disseminated intravascular coagulation was begun within 12 hours, he died only 30 hours after admission. The causative organism was detected from the blood and the contents of blisters, and was determined as Vibrio vulnificus. On autopsy, Vibrio vulnificus was also detected from skin and muscular tissue of his legs, but necrotizing fasciitis were not apparently revealed. Coagulating necrosis and acute tubular necrosis were verified in intestine and kidneys respectively probably due to ischemic changes. Pseudolobuli were formed and a small hepatocellular carcinoma was detected in the liver. Vibrio vulnificus has two infection channels; one is oral intake and the other is an external wound. The former is said to become serious. It has a rather short period from the starting of the symptom to death, and is highly fatal. If this bacteria is suspected by the clinical coarse of the patients or the laboratory examinations, it is necessary to dose effective antibiotics in its early stage. And for prevention, susceptible patients must be informed of the existence of this disease and the necessity of adequately heating raw seafood.     

Successful treatment of necrotizing fasciitis in an upper extremity caused by Clostridium perfringens after bone marrow transplantation

We report a 47-year-old man with acute leukemia who survived a severe case of necrotizing fasciitis caused by Clostridium perfringens involving his right upper extremity. On day 5 after stem cell transplantation, progressive local tissue necrosis led to septicemia and disseminated intravascular coagulation. Early diagnosis and prompt initiation of appropriate therapy, including surgical debridement and broad-spectrum antibiotics, were crucial. A recombinant thrombomodulin might have not only resolved the coagulation problem but also prevented multiple organ failure associated with the systemic inflammatory response.     

A successful treatment of progressive necrotizing myositis caused by Aeromonas veronii biotype sobria

We report a 52 year-old patient with malignant lymphoma who developed necrotizing soft tissue infection in the left lower extremity by Aeromonas veronii biotype sobria during a neutropenic period after intensive chemotherapy. We decided to amputate the involved leg when signs and symptoms of necrotizing myositis were progressing despite administration of sensitive antibiotics. He survived with subsequent intensive supportive care. It is to note that even though the patient's neutrophil count is zero, he or she should be treated aggressively by drainaging the lesion or even amputation of the involved extremities in combination with proper antibiotics.     

Vibrio vulnificus infection complicated by acute respiratory distress syndrome in a child with nephrotic syndrome

A 9-year-old girl with nephrotic syndrome visited a local hospital after developing fever, chills, and edematous changes and multiple hemorrhagic bullae on both legs over 2 days. Cultures of blood and an aspirate from the bullae yielded Vibrio vulnificus. The patient was transferred to our hospital because of persistent fever, generalized edema, acute renal failure, and disseminated intravascular coagulopathy. We treated this patient as a V. vulnificus infection complicated with necrotizing fasciitis. With minocycline and ceftazidime combination therapy was instituted. Emergency fasciotomy and continuous peritoneal dialysis were performed. The patient developed acute respiratory distress syndrome (ARDS) during the hospitalization, requiring intubation and mechanical ventilation. She eventually died. The histopathological findings showed diffuse alveolar damage with lobular pneumonitis. Hyaline membranes, composed of proteinaceous exudate and cellular debris, covered the alveolar surfaces. Microscopic examinations of lung could not distinguish the effects of cytolysin from other insults to lungs that occur in ARDS. This report highlights the postmortem pathological findings in V. vulnificus infection in a child with nephrotic syndrome complicated by ARDS.     

Two case reports of septic shock due to Vibrio vulnificus with liver cirrhosis

We have recently experienced a case of Vibrio vulnificus septicemia which occurred in a patient with hepatic cirrhosis, and as we were able to give early antibiotic treatment, the patient survived. We would like to report this case here together with another case experienced 2 years ago. Case 1 was a 58-year-old male who was attending our hospital as an outpatient for hepatic cirrhosis. At 5:30 pm on August 8, 1987, he consumed abalone and giant clam and at 9 pm complained of high fever with shaking chills. He was admitted to our department as an emergency case. Cefoperazone was administered resulting in a decline of fever on the following day. During the course of treatment he fell transiently into pre-DIC, but due mainly to the administration of antibiotics his condition was subsided. Case 2 was a 53-year-old male who was under medical care in our hospital for grave hepatic cirrhosis. On October 11, 1985, he consumed sushi and two days later suffered chills and pyrexia. A blood culture revealed Vibrio vulnificus. His condition improved transiently with administration of Cefazolin, but oliguria, hypotension and ascites occurred subsequently, and finally the patient died on the 22nd day.     

A fatal case of Vibrio vulnificus presenting as septic arthritis.

Vibrio vulnificus is an invasive gram-negative bacillus that may cause necrotizing cellulitis, bacteremia, and/or sepsis. Although V vulnificus infection is uncommon, it is frequently fatal and is usually attributed to ingestion of raw shellfish or traumatic exposure to a marine environment; patients are also often found to have a hepatic disorder (cirrhosis, alcohol abuse, or hemochromatosis) or an immunocompromised health status, and most commonly present with septicemia or a wound infection. We describe a patient who presented with septic arthritis as the first clinical manifestation of a V vulnificus infection. The organism was subsequently identified in a synovial fluid aspirate.     

Cervical necrotizing fasciitis associated with descending necrotizing mediastinitis

ABSTRACT: We report a case of potentially fatal cervical necrotizing fasciitis and descending necrotizing mediastinitis due to deep neck infection in a 66-year-old male patient with no history or evidence of immunocompromising disorders. On admission, he had painful neck movements and the skin over his neck was red, hot and tender. A computerized tomography (CT) scan of his neck and chest showed evidence of air collection in soft tissues. He was treated with broad-spectrum intravenous antibiotics and early massive cervical drainage. Prompt diagnosis by CT of the neck and chest enabled an early surgical treatment of cervical necrotizing fasciitis. Although acute mediastinitis is a fatal infection involving the connective tissues that fill the interpleural spaces and surround the median thoracic organs, an extensive cervicotomy combined with appropriate antibiotics can prevent the need for mediastinal drainage.     

Vibrio vulnificus septicemia

We report a case of Vibrio vulnificus infection in a middle-aged alcoholic man with Laennec's cirrhosis. The patient had recently received a puncture wound from the shell of a shrimp while fishing in the Gulf of Mexico. He presented with acrally distributed urticarial plaques, purpura, and bullae, as well as signs and symptoms of septic shock. Vibrio vulnificus was isolated from the blood, and histologic examination of the skin biopsy specimen demonstrated a devitalized, inflammatory, cell-poor superficial dermis and an acute cellulitis of the subcutis, with extensive tissue destruction. In addition, a necrotizing vasculitis, with a relative paucity of inflammatory cells but numerous bacilli around dermal vessels, was noted.     

Rapid detection of Vibrio vulnificus using a loop-mediated isothermal amplification method

Vibrio vulnificus is found in marine waters near the coast around the world. Infection with this gram-negative rod, via ingestion of raw seafood or via a skin wound following contact with contaminated estuarine or marine water, can cause necrotizing fasciitis and sepsis. Most of patients with Vibrio vulnificus infection have underlying liver dysfunction or diabetes mellitus. Due to the high mortality and short latent periods, control of this infection depends on early identification of the bacterial species and prompt initiation of intensive care. Accordingly, the development of a technique that can identify this microbe quickly and accurately is of great importance. Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification method to detect specific genes with rapidity and high sensitivity. In this study, we developed LAMP for the detection of Vibrio vulnificus. Using 28 Vibrio vulnificus strains and 53 other bacterial strains, we confirmed the high specificity of this method. Moreover, our LAMP method also showed high sensitivity, with a minimum detection level of one colony-forming unit per test. Furthermore, we developed simplified and conventional pretreatments for the method using experimental animal models. All of these attempts have lod to our non being able to detect Vibrio vulnificus within 1 hour.     

Vibrio vulnificus infection

We report 3 cases of Vibrio vulnificus infections from Taiwan. Patient 1, who manifested symptoms of primary septicemia, died after 2 days. Patient 2, who had a wound infection and signs and symptoms of sepsis but negative blood cultures, responded to tobramycin and chloramphenicol plus surgical debridement, and recovered after 26 days of hospitalization. Patient 3 had secondary septicemia originating from a wound inflicted by a shrimp. Originally, the patient seemed to respond to ceftazidime and amikacin treatment along with surgical debridement, but subsequently died from adult respiratory distress syndrome (ARDS) induced by several episodes of aspiration which occurred after initial clinical improvements. We conclude that, for patients with severe wounds and evidence of V. vulnificus infection, an appropriate, powerful antibiotic, such as one of the third generation cephalosporins should be used as initial therapy unless the nature of the infection indicates other treatment.     

Successful treatment of necrotizing fasciitis associated with diabetic nephropathy

A 50-year-old woman with a 15-year history of type 2 diabetes mellitus was admitted to our hospital due to high fever and a skin lesion with severe pain, swelling and a sensation of heat in the right thigh. Laboratory examination showed elevated C-reactive protein (CRP), thrombocytopenia, nephrotic syndrome and renal dysfunction. Her blood glucose level had been well controlled. Streptococcus agalactiae was detected in both the skin lesion and blood culture, and pathological examination revealed neutrophil infiltration in the fascia and muscle layer. The patient was diagnosed with necrotizing fasciitis, septic shock and disseminated intravascular coagulation. A combination therapy of antibiotics and surgical debridement resulted in the improvement of symptoms as supported by laboratory findings, and the skin lesion also showed improvement. Although group A streptococcus is well known to be implicated in the pathogenesis of necrotizing fasciitis, only S. agalactiae, belonging to group B streptococcus, was isolated from the tissue and blood cultures in this case. Although this organism is not virulent and rarely causes a necrotizing fasciitis, both the superficial fascial layer and underlying muscle were affected in this case. There have been only a few reports of necrotizing fasciitis due to S. agalactiae in patients with diabetes mellitus. Although the blood glucose level was well controlled in our patient, this disease might be caused by other factors, including diminished sense of touch and pain, abnormality of microcirculation and hypogammaglobulinemia due to nephrotic syndrome.     

Exploring the pathogenesis of necrotizing fasciitis due to Streptococcus pneumoniae

Monobacterial necrotizing fasciitis is a rare form of soft tissue infection usually caused by the group A beta-hemolytic Streptococcus. Soft tissue infection is an uncommon clinical manifestation of invasive disease due to Streptococcus pneumoniae. We describe 3 cases of pneumococcal necrotizing fasciitis and explore potential pathogen-specific mechanisms of pathogenesis. The clinical characteristics of necrotizing fasciitis due to S. pneumoniae and group A beta-hemolytic Streptococcus appear to overlap. The similarities include predominant occurrence in elderly adults with underlying chronic illness, predilection for lower extremity infection, progression to toxic shock-like syndrome and a high case fatality rate. No DNA fragments corresponding to speA, speB or speC were amplified by PCR from the 3 pneumococcal isolates. Western immunoblot revealed no evidence of SpeA, SpeB or SpeC protein expression. Evaluation for protease production and cytotoxicity was unrevealing. The similar clinical presentation of pneumococcal necrotizing fasciitis to the disease caused by the group A beta-hemolytic Streptococcus has important therapeutic implications. The molecular mechanisms underlying the pathogenesis are unclear. Prospective population-based studies are required to define the epidemiology of this infection.     

A case of fatal sepsis due to Vibrio vulnificus

A 66-year-old male with chronic alcoholic liver injury was admitted on July 27, 1986 to our hospital with complaints of high fever, convulsion and skin erythema. He had consumed raw fish 3 days before, and had a scratch wound over the right arm and left leg because he had slipped in a small stream in the woods the day before admission. He was already in shock state with sepsis of V. vulnificus and DIC on admission. Although the treatment with ABPC, CP, CAZ, MINO for sepsis, and Heparin & Antithrombin III for DIC was immediately begun, he died only 10 hours after admission. On autopsy, the skin lesion revealed phlegmon with necrotizing angitis and the liver showed fatty changes with Mallory's body. The causative organism was detected from the blood and on autopsy from the skin wound, bile juice, liver, spleen, kidney and bone marrow, and its type was determined as a V. vulnificus serovar 4. It was suspected that the route of infection in this case was the raw fish rather than via the wound because the water in which he had been wounded was fresh water and the bacterium was not detected from the water, shells, nor moss existing there.     

Tube thoracostomy-related necrotizing fasciitis: a case report

Spontaneous pneumothorax is a serious complication of pulmonary tuberculosis that requires immediate treatment. Necrotizing fasciitis is a serious, rapidly progressive infection of the subcutaneous tissue and fascia, most related to trauma or surgery. Here, we report a case of pulmonary tuberculosis with spontaneous pneumothorax. A standard procedure of tube thoracostomy was performed for lung re-expansion. Two days after the tube was removed, necrotizing fasciitis developed from the puncture site. Computed tomography of the chest showed focal thickness with gas formation and loss of the fat plane over the chest wall, which is compatible with the diagnosis of necrotizing fasciitis. Aggressive treatment was given, including emergency fasciectomy and adequate systemic antibiotic and antituberculous treatment. The necrotizing fasciitis was successfully treated. The patient was discharged and sent home with maintenance antituberculous therapy.     

Postoperative necrotizing fasciitis of the thorax in cardiac surgery

Necrotizing fasciitis is a rare soft tissue infection and a life-threatening emergency, often fatal. Its incidence and management are described plentifully in the medical literature regarding the most common anatomical sites involved like the abdomen, lower and upper limbs, and perineum. However, available data and case reports of chest wall necrotizing fasciitis after thoracic procedures are scarce, mainly after major cardiac operations. We report and discuss a case of necrotizing fasciitis of the chest wall occurring in the immediate postoperative period of a cardiac procedure, and include a brief review of the concepts, pathophysiology, and treatment reported in the medical literature. We emphasize the need for early diagnosis and urgent and effective surgical debridement. Of importance is the fact that we have not found any references in the literature to cases similar or equal to the one we describe here, which occurred in the postoperative period of a cardiac procedure.     

Vibrio vulnificus Septicemia After Handling Tilapia Species Fish: A Canadian Case Report and Review.

BACKGROUND: Vibrio vulnificus can cause a necrotizing soft tissue infection or primary septicemia; these infections are collectively known as vibriosis. This bacterium is commonly found within molluscan shellfish. Primary septicemia is often fatal, principally affecting persons with chronic liver disease. CASE PRESENTATION: A fatal case of V vulnificus sepsis that developed in a patient with chronic hepatitis B and chronic renal failure is reported. Diagnosis was made by isolation of the pathogen by blood culture. Upon further questioning, the patient's family recounted that the patient had handled and ingested Tilapia species fish in the hours preceding the patient's presentation. Despite treatment with doxycycline and cefotaxime, in conjunction with supportive care in the intensive care unit, the patient died on day 7 from multiple organ dysfunction. CONCLUSION: The present case highlights the need to consider V vulnificus in the microbiological differential diagnosis when a person presents with sepsis and bullous cutaneous lesions. The importance of educating patients with liver disease (and certain other chronic diseases) about the need to be cautious when handling or consuming seafood is underscored.     

Multi-limb necrotizing fasciitis in a patient with rectal cancer

Necrotizing fasciitis is a devastating soft tissue infection affecting fascias and subcutaneous soft tissues. Literature reviews have identified several related risk factors, including malignancy, alcoholism, malnutrition, diabetes, male gender and old age. There are only scanty case reports in the literature describing its rare association with colorectal malignancy. All published cases are attributed to bowel perforation resulting in necrotizing fasciitis over the perineal region. Isolated upper or lower limb diseases are rarely identified. Simultaneous upper and lower limb infection in colorectal cancer patients has never been described in the literature. We report an unusual case of multi-limb necrotizing fasciitis in a patient with underlying non-perforated rectal carcinoma.
