Halophilic, noncholera marine Vibrio bacteria can cause septicemia, gastroenteritis, cellulitis, and necrotizing fasciitis. We describe six patients with necrotizing fasciitis and review 12 cases described previously. The 18 patients included 14 men and four women. Their ages ranged from 32 to 79 years (average 58.1 years). Eleven patients were older than 55 years. Nine infections were caused by V. vulnificus, three by V. parahaemolyticus, and one by V. alginolyticus. In five cases the Vibrio species was not identified. Twelve patients had associated conditions that might have made them more susceptible to these infections, such as cirrhosis, steroid therapy, hemochromatosis, and multiple myeloma. These infections usually occur in apparently insignificant wounds (puncture wounds, insect bites) exposed to sea water or fish. Treatment is by debridement and antibiotic therapy. Three patients required amputation to control the infection. Six (33.3%) of the 18 patients died.

The patient was a 59-year-old man who had been in hospital suffering from aplastic anemia with transfusion hemosiderosis. Sudden onset of weakness, shaking chills and headache was observed after his staying out overnight on July 25, 1981. His temperature was 39.3 degrees C and he complained of abdominal pain and abdominal distension. His blood pressure dropped to a dangerous level and tonic convulsions that had begun in the upper body gradually extended to the whole body and he died 23 hours after his return. V. vulnificus was isolated by the blood culture performed before death. During his stay away from the hospital, he had eaten raw cuttlefish, which was considered to be the source of infection. V. vulnificus is one of the halophilic marine vibrios and is isolated frequently in summertime from the sea foods and sea water near Japan. It has been disclosed that the presence of underlying diseases such as liver cirrhosis, hemochromatosis can predispose a person to fatal sepsis by V. vulnificus. In this case, besides leukocytopenia, the presence of hemosiderosis induced by many transfusions was considered to be a major cause leading to the fulminating course of the disease.

Infections with Vibrio vulnificus resulting in septicemia and high mortality have been correlated with pre-existing liver disease and hemochromatosis. As these conditions are associated with impaired iron metabolism and as iron availability in the host has been implicated in the pathogenicity of a number of bacterial infections, the role of iron as a possible factor in the pathogenesis of V. vulnificus was examined. Injection of mice with iron resulted in a lowering of the 50% lethal dose from 10(6) to 1.1 cells and in a reduction in the time of death postinfection. Elevated serum iron levels were also produced by damaging livers with injections of CCl4. The inoculum size required to kill these mice was directly correlated with serum iron levels. Since the portal of infection of this organism may be ingestion of contaminated seafood, the effects of iron upon orally induced infection were also studied. The effects of adding iron, transferrin, or Desferal (an iron chelate) upon the growth of V. vulnificus in human and rabbit sera were also examined. Iron appeared to be the limiting factor in the ability of this organism to survive or grow in mammalian sera. These results, both in vitro and in vivo, provided strong evidence that iron may play a major role in the pathogenesis of V. vulnificus.

In clinical studies, frequent hepatic dysfunction associated with crises in sickle cell disease has been noted, but whether irreversible morphologic changes arise from these transient episodes is uncertain. We studied 70 patients with sickle cell disease (57 SS, 12 SC and one S-thalassemia (S-thal) hemoglobin) autopsied at The Johns Hopkins Hospital. They ranged in age from five months to 75 years (average 21 years) and 35 (50 percent) were female, In 64 patients (91 percent), livers were enlarged and had distention of Kupffer cells with phagocytized sickled red cells; this was massive in 10. In 19 patients (27 percent) the sinusoids were markedly distended with sickled red cells and appeared obstructed. Focal parenchymal necroses were present in 24 patients (34 percent) and were explained in 12, eight by cardiac dysfunction and four by sepsis. Reparative changes, portal fibrosis and regenerative nodules were each found in 14 patients (20 percent), only one of whom had a known history of viral hepatitis despite the frequency of transfusions. Cirrhosis of unknown cause was present in seven patients and cardiac cirrhosis in one. Cirrhosis with hemochromatosis was present in three patients and 30 others had parenchymal iron accumulation. Thus, unexplained hepatic necroses, portal fibrosis, regenerative nodules and cirrhosis were frequently encountered in these patients. This spectrum of liver disease appears to be best understood as a consequence of recurrent vascular obstruction, necrosis and repair arising as a component of sickle cell disease.

Rhinocerebral phycomycosis is an uncommon opportunistic infection with ubiquitous fungi of the class Phycomycetes, starting in the nose and extending to the paranasal sinuses and then intracranially. The condition is often characterized by poor prognosis because of occlusion of the internal carotid artery. This disease is commonly associated with predispositions such as uncontrolled diabetes mellitus, which is the most common, immunosuppressive states and metabolic bankruptcy including leukemia, lymphoma, myeloma, malnutrition, uremic or diarrheal acidosis, severe burns, anemia, carcinoma, radiotherapy, liver cirrhosis, hemochromatosis, tuberculosis, septicemia, long-term medication of steroid, antibiotics and antimetabolite, drug addiction, cytotoxic drug administration and AIDS. Cases with unknown predisposition, however, have been infrequently reported in the literature. The authors report a case of rhinocerebral phycomycosis in which concurrence of Candida species instead of the above-mentioned common predispositions was considered a potential predisposition. To our knowledge, only 1 report in which Candida species are referred to as a potential predisposition for this disease has been previously issued. A 85-year-old man was admitted to our hospital on March 2, 1994 because of generalized convulsion. He had received a total extirpation of an ascending colon cancer in July 1993. On admission, physical inspection showed no abnormalities and neurological examination revealed obtunded consciousness without other abnormalities. He had no diabetes mellitus. Hematological and blood chemistry values were normal except for CA19-9 of 45 U/ml.(ABSTRACT TRUNCATED AT 250 WORDS)

Between January 1989 and June 1993, a total of 470 liver transplantations were performed at King's College Hospital. Thirty-seven transplantations were performed in 34 patients with liver-based metabolic disease. There were 16 females and 18 males with a median age of 19 years (range 1 month to 62 years). There were 14 patients under 16 years of age. The indications for liver transplantation were Wilson's disease (n = 16), alpha 1-antitrypsin deficiency (n = 10), tyrosinaemia (n = 2), primary hyperoxaluria type 1 (PH1; n = 2), congenital haemochromatosis (n = 1), familial amyloidotic polyneuropathy (FAP; n = 1, familial hypercholesterolaemia) (n = 1) and Crigler-Najjar syndrome type I (CNS1; n = 1). These included two patients who received combined heart-liver grafts for familial hypercholesterolaemia and FAP, respectively. Two patients received combined liver-kidney transplants for PH1. There were four deaths: from sepsis (n = 2), acute hepatic vein obstruction in a left lateral segment graft (n = 1) and portal vein thrombosis with liver necrosis (n = 1). Three patients were retransplanted, one for chronic rejection and two for hepatic artery thrombosis, giving an overall graft survival of 81% and patient survival of 88% (30/34), at a mean follow-up of 34 months (range 10-64 months).

In convalescents after and in patients with sepsis, purulent meningoencephalitis, severe pneumonia the study of iron metabolism provided biochemical criteria of iron excess: low serum transferrin against high transferrin iron, elevated ferritin. The risk of hyperferremia rises considerably after blood or erythrocyte transfusions. The liver got affected in the presence of infectious toxicosis. The authors believe it risky to practice uncontrolled administration of iron preparations in subjects recovering from severe bacterial and inflammatory diseases in view of threatening hemochromatosis.

Vibrio vulnificus is a halophilic Vibrio that has been isolated repeatedly from sea-water and shellfish during the warm months of the year. It's a virulent pathogen for men and is frequently associated with overwhelming infections including sepsis, gangrene of extremities and high mortality rate. We encountered a 13-year-old boy who had a history of beta-thalassemia major with secondary hemochromatosis, suffering from vomiting, diarrhea, fever and hypotension. Physical examination revealed that ecchymosis, bullae and ulceration were noted over the left leg. Vibrio vulnificus was isolated from the blood. Initially, the patient did not respond to the appropriate antibiotics treatment, subsequently surgical debridement was performed. After that, the patient recovered gradually, and discharged home after 17 days of admission. In conclusion, when patients present with sepsis and/or characteristic skin lesion-hemorrhagic bullae, particularly those with thalassemia major, hemochromatosis or underlying liver disease and a history of marine exposure, clinicians should be alerted to this potentially fatal infection and should commence appropriate assessment and treatment immediately.

The case of a patient with abdominal crisis and shock without any discernible origin who died 36 hours after hospital admission despite maximal therapy is described. Gram-negative sepsis, peritonitis and haemochromatosis with hepatic siderosis was the post-mortem diagnosis. We consider spontaneous peritonitis arising from translocation of normal intestinal flora (E. coli) through the intact wall of the gut combined with the impaired ability of the reticulo-endothelial system to remove endotoxin to be the causative factors. It is unknown whether the adrenal insufficiency due to siderophilic adrenal hypophysis and adrenal glands contributed to the fulminant course of the disease. Undiagnosed liver cirrhosis and especially haemochromatosis should therefore be included in the differential diagnostic considerations in patients presenting with these symptoms, and in whom no obvious cause for a septic focus can be found.

Liver transplantation in neonates represents a major medical and technical challenge particularly in babies weighing less than 5 kg. The authors report the experience of 10 liver transplants in 9 babies (6 boys and 3 girls), mean age, 6 weeks (range, 2 to 11); median weight, 3.7 kg (range, 2.4 to 5). All had fulminant hepatic failure caused by neonatal haemochromatosis (n = 3), non-A non-B hepatitis (n = 3), total parenteral nutrition induced (n = 1), hepatitis B (n = 1), and hepatic haemangio-endothelioma (n = 1). One child underwent retransplantation for hepatic artery thrombosis. Immunosuppression was by Cyclosporine A-based triple therapy in all cases. All received a reduced size graft consisting of left lobe (n = 1), left lateral segment (n = 6) and monosegment III (n = 3). In nine cases the donor hepatic artery was anastomosed to an iliac artery conduit from the infrarenal aorta, and a Roux loop was used for bile duct reconstruction. Primary abdominal wound closure was possible in six patients, skin closure alone in one, and a silastic patch was used in three. Complications included infection (n = 5), bowel perforation (n = 2), diaphragmatic perforation (n = 2), bile leak (n = 1), hepatic artery thrombosis (n = 1), and portal vein thrombosis (n = 1). None of the babies experienced acute rejection. Currently five of the nine recipients are alive with good graft function at a mean follow-up of 22 months (range, 5 to 58). Of the four deaths, two were related to infection (one in combination with portal vein thrombosis), one to multiorgan failure and fluid overload, and one to early graft dysfunction and sepsis after undergoing retransplantation for hepatic artery thrombosis. From our experience liver transplantation offers a promising option for the treatment of severe liver disease in children less than 3 months old.
