BACKGROUND: Mivacurium is a nondepolarizing muscle relaxant and metabolized by pseudo-cholinesterase(pChe). Many reports show fall in pChe activity during pregnancy, so the metabolism of mivacurium may be delayed and muscle relaxation would be prolonged. METHODS: Muscle relaxation of full-term pregnant women(C group, n=10) and nopregnant women(Non-C group, n=10) was maintained by continuous infusion of mivacurium to keep 1st response of TOF at 5+/-1%. After discontinuance of infusion, recovery profiles were measured with accelerography. RESULTS: The Infusion rate of mivacurium to maintain 1st twich response of TOF at 5+/-1% was significantly low in C group comparing with Non-C group(P<0.05). There was no significant difference in pChe activity between two groups. There was no significant difference in recovery index, recovery time(T1 25%-T4 ratio, 0.75). There was a little correlation between the total infusion time and recovery profiles(recovery index: r2=0.37, recovery time: r2=0.28). Strong correlation existed between bolus-TS(time interval from the injection of mivacurium to recovery of 5% twitch hight) and infusion rate(r2=0.76). CONCLUSION: The mivacurium infusion rate of C group to maintain muscle relaxation was significantly lower than Non-C group. There would be many possible reasons including over-estimation of paturient body weight compared with lean body mass, decrease of blood volume due to hemorrhage.

One hundred and sixteen Korean adults with biopsy-proven acute viral hepatitis were studied to determine the etiology and the outcome of the disease using paired sera obtained during acute and convalescent phases. The prevalence of acute viral hepatitis A, B, D and non-A non-B were 3.4%, 60.3%, 0.9% and 35.3%, respectively: hepatitis B virus infection was the most common cause and the hepatitis D virus superinfection was almost negligible. Only eleven (26.8%) of 41 patients with AVH NANB were negative for all serological markers of HBV. The rest (73.2%) were positive for at least one HBV marker: HBsAg was positive in 31.7%. Therefore, the presence of HBV serologic markers in the sera does not exclude the diagnosis of AVH NANB in Korea. In patients with acute viral hepatitis B, 27% remained positive for HBsAg. Chronic hepatitis developed in 12.8% and 17% patients with acute hepatitis B and non-A non-B, respectively. Progression to chronic hepatitis in patients with acute viral hepatitis B and non-A non-B occurred more commonly, although statistically not significant, in male sex and in patients who did not have clinical jaundice during the acute phase and who showed bridging necrosis in their liver biopsies. Age did not influence the progression to chronic hepatitis.

BACKGROUND/AIMS: Thrombopoietin (TPO) is an important cytokine for megakaryocyte maturation and platelet production. Because the main site of its production is liver, the failing liver may have a role in thrombocytopenia in chronic liver disease. The aims of this study were to determine the serum TPO levels in cirrhotic patients with thrombocytopenia and clarify the relation between the serum TPO levels and liver function impairment. METHOD: Cirrhotic paitents with thrombocytopenia (LC, n=57, Child class A/B/C; 20/13/24), chronic hepatitis patients (CH, n=24), oncologic patients with thrombocytopenia induced by chemotherapy (HO, n=7), acute viral hepatitis patients (AVH, n=5) and healthy controls (HC, n=5) were enrolled. Serum TPO was measured by an ELISA method. RESULTS: Although the mean platelets counts of LC (69+/-32, x103/ul: mean+/-SD) were lower than those of HC (229+/-29, x103/ul), serum TPO levels in LC (108+/-63 pg/ml: mean+/-SD) were not significantly different from HC (122+/-24 pg/ml). In HO, serum TPO was significantly higher than LC (623+/-746 vs 108+/-63 pg/ml, p<0.05) inspite of comparable platelets counts. In LC, serum TPO level was not significantly different among Child class groups. It was not correlated with serum ALT, serum albumin levels, prothrombin time, serum bile acid, Child class, Child score and partial thromboplastin time, but weakly correlated with serum total bilirubin (p=0.038, r=0.288) and platelet counts (p=0.041, r=0.287). CONCLUSIONS: Although impaired hepatic production of TPO seems to be the main cause of low serum TPO levels in thrombocytopenic cirrhotic patients, there was no correlation between serum TPO level and the severity of liver dysfunction. The role of other factors such as megakaryocyte mass in bone marrow, portal hypertension and hypersplenism may be necessary to explain the putative mechanism between TPO and platelet numbers in liver cirrhosis with thrombocytopenia.
