ObjectiveTo investigate the occurrence, development, treatments and prognosis of ischemic type biliary lesions (ITBL) complicated with portal hypertension after liver transplantation (LT). MethodsClinical data of 32 ITBL patients with portal hypertension after LT in Liver Transplantation Center, the Third Affiliated Hospital of Sun Yat-sen University from January 2003 to April 2009 were analyzed retrospectively. The informed consents of all patients were obtained and the ethical committee approval was received. There were 28 males and 4 females with a mean age of (46±14) years old. The patients were followed up regularly and the occurrence, development, treatments and prognosis of portal hypertension were observed.ResultsWhen ITBL was diagnosed, mild splenomegaly was found in 11 cases, moderate splenomegaly in 14 cases and severe splenomegaly in 4 cases. Three cases were observed without splenomegaly. During the follow-up period, 5 cases were observed in stable states with mild splenomegaly or splenomegaly improving from moderate to mild. While for the other 27 cases, portal hypertension symptoms like splenomegalyetc. were observed becoming worse as ITBL developed including 11 cases with severe splenomegaly. Esophageal and gastric fundus varices were found in 53% (17/32) of the patients including 2 cases of lower esophagus mild varices, 8 cases of lower esophagus and gastric fundus mild to moderate varices, and 7 cases of moderate to severe varices. All the patients received intervention treatments via endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC). Liver retransplantation was performed in 11 cases, choledochojejunostomy in 4 cases and choledocholithiasis + biliary tract exploration in 1 case. Eighteen cases survived and 14 cases died. Four cases died of aggravating jaundice and liver failure, 4 liver cancer recurrence, 3 massive hemorrhage in upper gastrointestinal tract, and 1 severe infection, 1 multiple organ failure, 1 renal failure after liver retransplantation.ConclusionsMost of ITBL patients with portal hypertension after LT gradually deteriorates with the progression of ITBL. The treatments mainly include intervention treatments, liver retransplantation, and choledochojejunostomy. The prognosis is very poor.

Objective To analyze clinical characteristics of severe community-acquired pneumonia during pregnancy and its outcomes, and to explore the relevant risk factors. Methods From September 2012 to September 2017,324 398 pregnancies admitted in 7 tertiary hospitals were included. Clinical data of 33 cases of pregnancies with severe community-acquired pneumonia(severe pneumonia group)and 214 cases of pregnancies with common community-acquired pneumonia (control group) were reviewed retrospectively, including the clinical information, manifestations, laboratory examinations and pregnancy outcomes. Relevant risk factors were analyzed by multivariate logistic regression analysis. Results (1) General data: pregnancies with severe community-acquired pneumonia accounted for 0.010%(33/324 398) of hospitalized pregnancies, the gestational age of two groups were(28±8)and(23±8)weeks, body mass index were(21.7±2.1)and(25.5±3.4)kg/m2, rate of low income were 54.5%(18/33)and 31.8%(68/214), respectively. The differences between two groups were all statistically significant(all P<0.05). No significant differences were found in age, pregnancy and parity times, rate of main pregnant complications such as diabetes and hypertension, educational level, asthma and onset seasons between two groups(all P>0.05). (2)Clinical data: the severe pneumonia group had significantly higher incidence of fever [100.0%(33/33)vs 75.2%(161/214)], shortness of breath(90.9% vs 16.8%)compared with the control group(all P<0.05).The median peripheral leukocytes counts were 12.3×109/L and 10.2×109/L, the hemoglobin level were(84±18) and(107±14)g/L,the albumin level were(26±4)and(37±3)g/L, the median serum urea nitrogen level were 3.7 and 2.4 mmol/L,the serum creatinine level were(72±25)and(45±11)μmol/L, respectively in two groups. The differences were all statistically significant (all P<0.05). No significantly statistical differences were found in coagulation indicator and cardiac function between two groups(all P>0.05).(3) Treatments: in severe pneumonia group, 12 patients(36.4%,12/33)needed invasive mechanical ventilation, 9 patients(27.3%,9/33)needed non-invasive mechanical ventilation, average time of mechanical ventilation was(7±4)days;8 patients(24.2%,8/33)with septic shock needed vasoactive drugs. However, there was no patient in control group needing mechanical ventilation and vasoactive drugs.(4)Pregnant outcomes: one patient(3.0%,1/33)died in the severe pneumonia group, while no death occurred in the control group. The hospital stay between two groups were(15.1±4.1)and(7.0±1.9)days, the rates of abortion and stillbirth between two groups were 42.4%(14/33)and 3.3%(7/214), the rates of premature were 10/19 and 6.3% (13/207), the rates of cesarean were 15/19 and 43.0%(89/207), the rates of low birth weight newborn were 17/19 and 14.0%(29/207), the rates of infected newborn were 15/19 and 10.1%(21/207), the birth weights were(2 165±681)and(3 102±400)g, respectively. The differences between two groups were all statistically significant(all P<0.05).(5)Multivariate logistic regression analysis demonstrated that anemia, low body mass index, hypoproteinemia were risk factors for severe pneumonia in pregnancy(all P<0.05). Conclusions Pregnancy with severe community-acquired pneumonia may be complicated by multiple organ dysfunctions, lead to adverse outcomes. Anemia, malnutrition are risk factors for pregnancy with severe pneumonia. Active and effective treatment may improve its prognosis.
