Aeromonas, a genus of gram-negative bacteria normally found in water and soil, is well established as a pathogen in the animal kingdom. Often considered as a pathogen of low virulence, its role in human infections has recently been recognised. Aeromonas infections in humans range from cellulitis to septicaemia. Endocarditis is rare. We describe here a patient with a chronic liver disease with aeromonas bacteremia and endocarditis.

Bacterial infection is a serious and often fatal complication of patients with liver disease and can prove fatal either directly or by precipitation of gastrointestinal bleeding, renal failure, or hepatic encephalopathy. At greatest risk are patients with alcoholic cirrhosis or decompensated chronic liver disease, or cases of acute liver disease who progress to fulminant hepatic failure or subacute hepatic necrosis. Infection appears to be unusual in patients with primary biliary cirrhosis. The site and type of infection is unrelated to the aetiology of the liver disease. Bacteraemia, pneumonia, urinary tract infection and spontaneous bacterial peritonitis are most common but infective endocarditis and meningitis, especially with pneumococci, are easily overlooked. Clinical suspicion of infection must be high as the only indication may be a general deterioration in the patients' clinical state, increasing encephalopathy or renal impairment. In the case of patients with fulminant hepatic failure, infection may precipitate the initial or recurrent encephalopathy and contributes to death in 10% of fatal cases. Spontaneous bacterial peritonitis is now recognized to occur in the absence of clinical features of peritonitis. The PMN content of the ascitic fluid may provide the only indication of infection and is the most readily available screening test. The most common types of organism responsible for all types of infection are Gram-negative enteric and streptococci, especially pneumococci, while infection with anaerobes is rare. Risk factors for infection include decompensated alcoholic liver disease, fulminant hepatic failure, gastrointestinal bleeding, invasive practical procedures and impaired host defence mechanisms against infection. Of the host defence mechanisms, impaired function of the reticuloendothelial system, complement, and PMNs represent the most common and serious defects. Defects of humoral immunity are present in ascitic fluid from patients with cirrhosis and are probably a major reason for development of spontaneous bacterial peritonitis. Diuresis improves these functions and reduces the risk of peritonitis. Treatment of infections even with the appropriate antibiotic is still associated with a high mortality but the use of adjuvant gut sterilization is promising, particularly in cases infected with Gram-negative enteric organisms. Infusions of fresh frozen plasma, blood and cryoprecipitate improve some systemic host defences and may be beneficial in the treatment and reduction of risk of infection.

Splenomegaly was studied retrospectively at the University of California, San Francisco, School of Medicine, on all patients (N = 2,056) for the years 1913 to 1962. The patients were classified into several diagnostic groups, and these groups were tested for statistical significance (chi(2)) with many clinical and laboratory variables to determine their predictive value. Hematologic disorders were associated with 57% of cases of splenomegaly and 81% of cases of massive splenomegaly. Among patients with splenomegaly, 19% had infectious diseases, 11% had hepatic diseases, and 9% had congestive or inflammatory disorders. The residual 4% were considered to have primary splenic disorders or a disorder of unknown cause. The commonest diseases associated with splenomegaly were hematologic (acute and chronic leukemias), infectious (malaria, endocarditis, and tuberculosis), hepatic (chronic liver disease), congestive (congestive heart failure), inflammatory (thyrotoxicosis), and other (cancers not metastatic to the spleen). The diseases most frequently associated with massive splenomegaly were the chronic leukemias. The disease with the highest incidence of massive splenomegaly was myelofibrosis (23 of 29 patients, 78%). Splenectomy was performed in 154 patients (7%), primarily for hematologic amelioration and hepatic hypersplenism. Hematologic diseases showed significant associations with lymphadenopathy, generalized lymphadenopathy, massive splenomegaly, and cytoses (P .001) and with progressive splenic enlargement (P < .02). Infectious diseases showed significant association with fever, and hepatic diseases showed significant association with abnormal results of liver function tests (P < .001). The findings of this retrospective study should be validated prospectively.

Splenomegaly was studied retrospectively at the University of California, San Francisco (UCSF), School of Medicine in 301 patients from 1963 to 1995 and compared with the UCSF service of the San Francisco General Hospital Medical Center (SFGH) in 148 patients from 1979 to 1994. The combined 449 patients were classified into several diagnostic groups and were studied by means of several clinical and laboratory associations. Hepatic disease in the percentage of patients at UCSF (with those at SFGH given in parentheses) was associated with splenomegaly in 29% (41%), hematologic disease, 32% (16%); infectious diseases, 16% (36%); congestive or inflammatory disease, 10% (4%); primary splenic disease, 6% (1%); other, 5% (1%); and cause unknown, 2% (1%). Massive splenomegaly occurred in 27% of the patients of the combined series, particularly in patients with hematologic diseases. The acquired immunodeficiency syndrome (AIDS) occurred in more than half of the patients with infectious diseases at SFGH and was four times frequent than in the patients at UCSF. The commonest diseases associated with splenomegaly were hematologic (lymphoma), hepatic (chronic liver disease), infectious diseases (AIDS and endocarditis), congestive (congestive heart failure), primary splenic (splenic vein thrombosis), and other (malignancy not metastatic to the spleen). In 11 patients with AIDS and massive splenomegaly, Mycobacterium avium complex occurred in 8 (73%). Splenectomy was performed in 117 patients (26%), primarily for hematologic amelioration. I conclude that for splenomegaly of unknown origin, the invasive procedure of choice for patients with hematologic associations may be a bone marrow biopsy; for hepatic association, a liver biopsy; and for infectious disease associations, a lymph node biopsy, before any consideration of a diagnostic splenectomy.

Cirrhosis is associated with several circulatory abnormalities. These include hyperkinetic systemic and splanchnic circulation, hepatopulmonary syndromes including pulmonary hypertension, and cirrhotic cardiomyopathy. Hepatopulmonary syndrome generally refers to hypoxaemia seen in patients with chronic liver disease and appears to be relatively common, although often subclinical. However, significant pulmonary hypertension occurs in 0.2-0.7% of cirrhotic patients. Nitric oxide and/or other vasodilators appear to be involved in the pathogenesis of hepatopulmonary syndrome through induction of pulmonary capillary dilatation which increases the alveolar-arterial oxygen gradient. Cirrhotic cardiomyopathy refers to abnormal left ventricular function which is manifested under conditions of physiological or pharmacological stress. The emergence of liver transplantation as an effective treatment for end-stage liver disease has led to recognition of previously subclinical cardiomyopathy and congestive heart failure accounts for significant morbidity and mortality after this procedure. Diminished myocardial beta-adrenergic receptor function has been shown to play an important role in the pathogenesis of this condition. The contributions of other factors including nitric oxide, catecholamines and membrane fluidity changes are under investigation. Cirrhotic patients also have an increased incidence of other cardiac abnormalities, such as endocarditis and pericardial effusions.

Splenic infarct is a rare condition often related to haematological, cardiovascular, autoimmune or infectious diseases diagnosed with increasing frequency due to the large use of abdominal imaging techniques. Cryoglobulins are serum proteins that reversibly precipitate at low temperatures, small vessels vasculitis represent their most common clinical manifestation and are often associated with chronic liver disorders or with lymphoproliferative diseases. Here the authors report the cases of two patients, both affected by chronic liver disease associated with cryoglobulinemia, admitted to our unit for an on-going active infectious disease (without signs of endocarditis) who presented multiple splenic infarcts as an unexpected complication. The authors hypotize that in both cases splenic infarct may be related not only to a thrombogenic state or to splenic vasculitis but also to other immuno-mediate mechanism related to cryoglobulins synthesis and clearance.

The diagnosis of pituitary dysfunction is very difficult in inpatients with liver cirrhosis, because the symptoms are intricate and similar. We here report a case of a male patient complaining of fatigue and anorexia for more than two years. On duration of hospital stay, hyponatremia was irreformable. Magnetic resonance imaging of the pituitary revealed the presence of cystic pituitary and abnormal signal in the left frontal lobe. The patient was also suspected to be infective endocarditis. Recognition of this unusual complication of this condition is important for the patients with chronic liver disease.

Infective endocarditis (IE) is a life threatening disease requiring lengthy hospitalizations, complex multidisciplinary management and high health care costs. In this study, we analyzed the National Readmissions' Database (NRD) to identify infective endocarditis cases and the causative organisms, clinical determinants, length of stay, in-hospital mortality, and 30-day hospital readmission rates. The study cohort was derived from Healthcare Cost and Utilization Project's National Readmission Database between 2010-15. We queried the National Readmissions' Database using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnostic code for infective endocarditis (421.0) and identified a total of 187,438 index admissions. SAS 9.4 (SAS Institute Inc., Cary, NC) was utilized for statistical analyses. A total of 187,438 patients with a primary diagnosis of IE were identified over 6 years (2010-2015). Twenty-four percent (44,151 patients) were readmitted within 30 days. Most common etiologies for readmission included sepsis (14%), acute heart failure (8%), acute kidney injury (6%), intracardiac device infection (5.6%) and recurrence of IE (2.7%). Predictors of increased readmissions included female sex, staphylococcus aureus infection, diabetes, chronic lung disease, chronic liver disease, acute kidney injury, acute heart failure and anemia. In-hospital mortality for the readmission of IE was 13%, and average length of stay during the re-admission was 12 days. IE is associated with high rates of index admission mortality and for 30-day readmissions of which are associated with a substantial risk of death.
