Assessment of malnutrition in patients with liver cirrhosis / 대한내과학회지

BACKGROUND: Malnutrition frequently occurs in patients with liver cirrhosis independently for its etiology and can modify prognosis of the disease. Since malnutrition was observed at all clinical stages, but more frequently seen at advanced stages, early and detailed nutritional assessment in all patients with liver cirrhosis is important. The aims of this study are to define the nutritional status and the difference of nutritional index according to etiology and Child classification in patients with liver cirrhosis in Korea. METHODS: A total 138 cirrhotic patients (41 alcoholic cirrhosis, 97 virus-related cirrhosis) were studied. The diagnosis of cirrhosis was based on clinical, laboratory and ultrasonographic criteria and liver biopsy. The patients were divided into three groups according to the severity of their liver disease as assessed by the Child-Pugh classification. Nutritional parameter of protein (serum albumin, serum transferrin, total lymphocyte count) were measured. RESULTS: The patients with protein malnutrition are as follows: albumin 55, transferrin 68, total lymphocyte count 8. The frequency of moderate to severe protein malnutrition was high in alcoholic cirrhosis.: albumin (<2.9 g/dL) (26.8% vs 17.5%), transferrin (<180 mg/dL) (48.5% vs 24.8%), total lymphocyte count (<1200 number/L) (2.4% vs 2.0%). The mean value of nutritional index correlated with the degree of liver function impairment. (Child C showed the lowest value). CONCLUSION: In spite of limitation of nutritional index in this study, our study showed that severe protein-energy malnutrition was rare in Korea, and protein-energy malnutrition was not only more common in alcoholic cirrhosis but related to the severity of liver disease. Therefore, our data suggests that clinician should understand the importance of not imposing unnecessary restrictions and supplementation on protein intake for fear of imbalance of nutrition.

Pure Red Cell Aplasia Due to Parvovirus B19 in Renal Transplants / 대한신장학회잡지

Parvovirus B19 infection is known to cause chronic anemia in immunocompromised hosts, including organ transplant recipients. We report a case of pure red cell aplasia caused by parvovirus B19 in renal transplants. The patient was 16-year-old male who was diagnosed as chronic renal failure 7 years ago and had been on hemodialysis twice a week. He got renal transplantation in June 1999. But anemia was not improved in first postoperative period. On admission hemoglobin was 43.0 g/L, hematocrit was 12.7%. The bone marrow biopsy revealed severe erythroid hypoplasia with giant pronormoblasts. The pronormoblasia with giant prominent intranuclear inclusions, characteristic of parvovirus B19 infection. The parvovirus B19 PCR and anti-parvovirus B19 IgM were positive. The patient was treated with intravenous immunoglobulin and then reticulocyte count was increased 5 days later. Hemoglobin level restored to 104 g/L teo months later.

Changes of Propranolol Pharmacokinetic Parameters According to Hepatic Fibrotic Severity in CCl4-Treated Rats / 대한간학회지

BACKGROUND/AIMS: This study was designed to determine the effect of hepatic fibrotic severity on pharmacokinetics of propranolol in CCl4-treated rats. METHODS: 1 mL/kg of 10% CCl4 in olive oil was injected intramuscularly to rats twice weekly for 4, 6, 8 and 10 weeks, respectively (n=6). Control (n=6) was a sham-injected equal dose of olive oil for 10 weeks. After intravenous bolus injection of 2 mg/kg propranolol to rats, the serum propranolol concentrations were analyzed for 4 hours at various time points by a HPLC-fluorimetric system, and pharmacokinetic parameters such as C0, MRT, AUC, Vdss, t1/2( ) and CLp were determined. Then, a small amount of hepatic tissue was obtained and subjected to determination of the hepatic 4-hydroxyproline content, which confirmed the hepatic fibrotic severity. RESULTS: The serum concentrations of propranolol at 0.5, 1, 2 and 4 hours were significantly increased in CCl4-treated rats (p<0.01). In proportion to the duration of CCl4 treatment, C0 and AUC were significantly increased, and Vdss and CLp were significantly decreased (p<0.001). But MRT and t1/2( ) were not significantly changed. The hepatic 4-hydroxyproline content was gradually increased in CCl4-treated rats (p<0.001). CONCLUSION: Gradual changes in pharmacokinetic parameters of propranolol were seen to be dependent on the hepatic fibrotic severity. We suggest that gradual dosage modification, according to their hepatic fibrotic severity, is necessary for many drugs administered to patients with chronic liver disease.

A Case of Protein-Losing Enteropathy Associated with Systemic Lupus Erythematosus / 대한류마티스학회지

Systemic lupus erythematosus (SLE) is a multisystemic disease that can affect most organ system, although gastrointestinal (GI) manifestations are relatively uncommon. Protein losing enteropathy (PLE) is associated with several clinical disorders, but it is an unusual manifestation of SLE. Of over 20 reported cases of PLE associated with SLE, the pathogenesis of lupus associated PLE remains unclear. We describe a patient with edema, diarrhea, abdomianl pain, and hypoalbuminemia who had been diagnosed SLE. PLE was diagnosed by the method of alpha1-antitrypsin clearance in stool.

A Case of Delayed Hemolytic Transfusion Reaction with Acute Renal Failure Caused by Anti-E Antibody / 대한수혈학회지

A delayed hemolytic transfusion reaction (DHTR) is the result of delayed anamnestic alloantibody response four to fourteen days after transfusion of apparently compatible blood. Most DHTRs are very mild and may not be recognized clinically. Some are manifested only by anemia. Only a few cases are severe enough to induce a massive hemolytic reaction followed by frank renal failure. Recently, we experienced a case of DHTR with acute renal failure (ARF) due to anti-E. A 21-year-old woman received compatible four units of packed red cells after right artificial total hip replacement arthroplasty due to juvenile rheumatoid arthritis. She had a history of transfusion 4 years ago. Fourteen days after the transfusion, she showed a fall in hematocrit, hemoglobinuria and a positive indirect antiglobulin test, and accompanied by ARF. Anti-E was identified in the patient's serum by antibody screening and identification test at that time. She recovered from ARF after hemodialysis with conservative management. However, eventually, she died due to disseminated intravascular coagulopathy.
