Renal Dysfunction Induced by Bacterial Infection other than Spontaneous Bacterial Peritonitis in Patients with Cirrhosis: Incidence and Risk Factor

BACKGROUND/AIMS: Deterioration of renal function in cirrhotic patients with spontaneous bacterial peritonitis (SBP) is a predictor for in-hospital mortality; however, the clinical significance of renal dysfunction during bacterial infection other than SBP is unknown. The aim of this study was to investigate the prevalence and clinical significance of renal dysfunction due to bacterial infections other than SBP in patients with liver cirrhosis. METHODS: Retrospective data from inpatients with bacterial infections other than SBP were analyzed. RESULTS: Eighty patients were recruited for the analysis. The types of infections included that of urinary tract (37.5%), pneumonia (23.8%), biliary tract (20%), cellulitis (12.5%), and bacteremia of unknown origin (6.3%). Renal dysfunction developed in 29 patients (36.3%), of which 11 patients had irreversible renal dysfunction. The initial MELD score, neutrophil count, albumin, and blood pressure were significant risk factors in the univariate analysis, whereas only the MELD score was an independent risk factor for the development of renal dysfunction (p<0.001) after multivariate analysis. CONCLUSIONS: The prevalence of renal dysfunction during bacterial infection other than SBP in patients with liver cirrhosis was 36.3%, and its development was related to the severity of the liver disease. Occurrence of irreversible renal dysfunction seemed to affect the prognosis of these patients.

The Association Between the Serum Sodium Level and the Severity of Complications in Liver Cirrhosis

BACKGROUND/AIMS: Dilutional hyponatremia associated with liver cirrhosis is caused by impaired free water clearance. Several studies have shown that serum sodium levels correlate with survival in cirrhotic patients. Little is known, however, regarding the relationship between the degree of dilutional hyponatremia and development of cirrhotic complications. The aim of this study was to evaluate the association between the serum sodium level and the severity of complications in liver cirrhosis. METHODS: Data of inpatients with cirrhotic complications were collected retrospectively. The serum sodium levels and severity of complications of 188 inpatients were analyzed. RESULTS: The prevalence of dilutional hyponatremia, classified as serum sodium concentrations of < or =135 mmol/L, < or =130 mmol/L, and < or =125 mmol/L, were 20.8%, 14.9%, and 12.2%, respectively. The serum sodium level was strongly associated with the severity of liver function impairment as assessed by Child-Pugh and MELD scores (p<0.0001). Even a mild hyponatremia with a serum sodium concentration of 131-135 mmol/L was associated with severe complications. Sodium levels less than 130 mmol/L indicated the existence of massive ascites (OR, 2.685; CI, 1.316-5.477; p=0.007), grade III or higher hepatic encephalopathy (OR, 5.891; CI, 1.490-23.300; p=0.011), spontaneous bacterial peritonitis (OR, 2.562; CI, 1.162-5.653; p=0.020), and hepatic hydrothorax (OR, 5.723; CI, 1.889-17.336; p=0.002). CONCLUSIONS: Hyponatremia, especially serum levels < or =130 mmol/L, may indicate the existence of severe complications associated with liver cirrhosis

Microbiologic Study of the Bile Culture and Antimicrobial Susceptibility in Patients with Biliary Tract Infection / 대한소화기학회지

BACKGROUND/AIMS: Bacterial infection of biliary tract may cause severe inflammatory response or sepsis. An immediate bile culture and appropriate antibiotic administration are important to control the biliary tract infection. The objective of the study was to identify organisms in bile and the features of antibiotic susceptibility in patients with biliary tract infection. METHODS: We retrospectively reviewed the clinical records of 212 patients whose bile had been cultured for variable biliary tract diseases at Inje University Ilsan Paik Hospital from Jan. 2000 to Feb. 2007. Bile samples were obtained from percutaneous transhepatic biliary drainage (PTBD, n=89), percutaneous transhepatic gallbladder drainage (PTGBD, n=14) or endoscopic naso-biliary drainage (ENBD, n=49). RESULTS: The overall positive rate of bile culture was 71.7% (152 cases). The organisms cultured were Escherichia coli (25.0%), Enterococcus spp. (13.4%), Klebsiella spp. (11.1%), Pseudomonas spp. (11.1%), and coagulase-negative Staphylococcus (9.7%) in decreasing order. Effective antibiotics for Gram-negative organisms were amoxicillin/clavulanic acid, amikacin, imipenem, and piperacillin/tazobactam in order of effectiveness. Of the cultured blood samples from 160 patients, fifty (31.2%) showed positive bacterial growth. The organisms isolated from blood were similar to those found in the bile. CONCLUSIONS: A broad spectrum penicillin/beta-lactamase inhibitor is a recommendable antimicrobial for empirical treatment for biliary tract infection. However, Gram-positive bacteria such as Enterococcus spp. or methicillin-resistant Staphylococcus aureus are emerging as causative microorganisms. If these organisms are isolated, antimicrobial drugs should be replaced by narrower-spectrum antimicrobials.

A Case of Primary B Cell Mucosa-associated Lymphoid Tissue Lymphoma Presenting as a Solitary Rectal Mass / 대한소화기내시경학회지

Primary extranodal B cell lymphoma of mucosa- associated lymphoid tissue (MALT) can develop in diverse anatomic locations such as the stomach, salivary gland, thyroid, lung, and breast. Its distribution in the GI tract is as follows: 50~60% in the stomach, 20~30% in the small intestine and ileocecal area and 10% in the colorectal area. Although autoimmune and infectious diseases are known as the main etiologies, H. pylori infection has been clearly shown to play a causative role in lymphomagenesis, especially in the stomach. H. pylori eradication therapy only can induce disease remission nearly in 80% of the cases of gastric MALT lymphoma. However, there is lack of evidence for the extragastric area. In this case, a 71-year-old woman with low abdominal pain was diagnosed as having a rectal MALT lymphoma that was noted as a solitary rectal mass in a colonoscopic examination. Remission induction was commenced by H. pylori eradication and radiation therapy.

A Case of Spontaneous Left Atrial Intramural Hematoma Causing Vaso-occlusive Cardiogenic Shock

Intramural hematoma of the cardiac muscle is a rare clinical condition. Only a few cases have been reported in the medicosurgical conditions related to post cardiac surgery, chest trauma and dissecting aneurysms of the aorta. Moreover, there are few cases of spontaneous left atrial intramural hematoma and they may occur in the medical conditions related to calcified mitral annulus dissection or amyloidosis. We experienced a case of spontaneous intramural left atrial hematoma in a 29 year-old male resulting in vaso-occlusive cardiogenic shock. We report the clinical manifestation and treatment of this case with a review of literatures.

A Case of Primary Neuroendocrine Carcinoma of Liver Presenting with Liver Abscess / 대한소화기학회지

Primary hepatic neuroendocrine cell carcinoma is a very rare tumor. We experienced a 75-year-old woman with primary hepatic neuroendocrine carcinoma presenting with pyogenic liver abscess. Abdominal CT scan revealed a multiseptated liver abscess and an enlarged lymph node in portocaval portion. We performed percutaneous drainage of the liver abscess, but the amount of drained pus did not decrease after 20 days. The follow-up abdominal CT scan showed that the cystic portion of liver abscess had been replaced by the solid tumor. Microscopic examination of the tumor tissue showed nests of epithelial cells with uniform round hyperchromatic nuclei and high nuclear to cytoplasmic ratio. Immunohistochemical staining was strongly positive for synaptophysin and chromogranin A.

A Case of Hemosuccus Pancreaticus Showing Active Bleeding from the Ampulla of Vater / 대한소화기내시경학회지

Hemorrhage through the pancreatic duct into the duodenum, so called 'hemosuccus pancreaticus', is a rare cause of gastrointestinal bleeding with diagnostic difficulties. We report a 44-year-old man with recurrent upper gastrointestinal bleeding due to rupture of pseudoaneurysm into the pancreatic duct. Initial upper gastrointestinal endoscopy failed to identity the site of the hemorrhage. Active bleeding from the ampulla of Vater in duodenum was found on repeat endoscopy. Abdominal computed tomography disclosed pseudoaneurysm arising from the splenic artery caused by chronic pancreatitis. Splenic angiogram showed large psudoaneurysmal sac with wide neck, arising from distal splenic artery. Angiographic embolization was successful in controlling the arterial hemorrhage. The patient remained symptom-free 5 months after the embolization. Hemosuccus pancreaticus, although rare, remains important in the differential diagnosis of upper gastrointestinal bleeding of obscure orgin.
