AbstractBackgroundNeonatal jaundice and elevated levels of liver enzymes are found in infants with breast milk jaundice (BMJ).ObjectivesTo determine the prevalence and duration of elevated serum levels of liver enzymes in Thai infants with BMJ.MethodsWe conducted a prospective study of Thai infants with BMJ, excluding those with pathological causes of jaundice. We measured the serum levels of total bilirubin (TB), aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and γ-glutamyl transferase (GGT); followed infants with elevated levels; and estimated the time for levels to become normal using Kaplan–Meier analysis.ResultsWe included 42 infants (median age: 17.5 days) with BMJ, and elevated serum levels of at least 1 enzyme were found in 27 (64%) infants. We excluded 4 (10%) infants because they did not continue to be exclusively breastfed, 17 (40%) were lost to follow-up, and 21 (50%) completed the study. We found that 19 (45%) of the 42 infants had elevated GGT, 11 (26%) had elevated ALT, and 9 (21%) each had elevated AST and ALP levels. The median time for enzyme levels to normalize was 291 days (95% confidence interval [CI], 109.8 to 472.2) for ALT, 240 days (95% CI, 139.0 to 340.9) for AST, 184 days (95% CI, 4.4 to 363.6) for ALP, 120 days (95% CI, 74.6 to 164.5) for TB, and 63 days (95% CI, 61.44 to 64.6) for GGT. Infants were otherwise healthy during the follow-up.ConclusionThe prevalence of elevated serum levels of liver enzymes in Thai infants was unexpectedly high, but the levels became normal spontaneously despite continued breastfeeding, which endorses a “watchful waiting” strategy in managing asymptomatic infants with BMJ.

Abstract Background Anti-mitochondria autoantibodies (AMA) occur in > 95% primary biliary cholangitis (PBC) patients. Biochemically normal AMA-positive (BN/AMA+) individuals, occasionally noticed by indirect immunofluorescence (IIF) on HEp-2 cells and confirmed in AMA-specific assays, may represent early stages of PBC. The Enhanced Liver Fibrosis (ELF) score is a surrogate marker for liver fibrosis. This prospective study investigated the ELF score in BN/AMA+ individuals and PBC patients, considering autoantibody avidity and serum levels along the years. Methods 327 samples from 35 PBC and 59 BN/AMA+ were prospectively obtained in average 3.83 (range 0.50–7.40) years apart. Samples were tested by IIF on rat-kidney (IIF-AMA), western-blot for AMA (WB-AMA), and ELISA for antibodies against pyruvate-dehydrogenase (PDC-E2), gp210, sp100 and CENP-A/B. Anti-PDC-E2 avidity was determined by 6 M urea-elution ELISA. Alkaline phosphatase (ALP), gamma glutamyl transferase (ɣGT) and ELF score were measured by automated methods. Results Along the follow-up period BN/AMA+ subjects and PBC patients presented significant increase in serum anti-PDC-E2 (mean 10.45% and 8.86% per year; respectively), anti-PDC-E2 avidity (3.02% and 4.94%/year) and ELF score (3.24% and 2.71%/year). IIF-AMA and ɣGT increased in BN/AMA+ (6.59% and 2.36%) and decreased in PBC (− 4.89%/year and − 3.88%/year). In BN/AMA+ individuals there was positive correlation of ELF with IIF-AMA titer (r = 0.465; p < 0.001) and with anti-PDC-E2 levels (r = 0.239; p < 0.001). Expansion of autoantibody targets along time occurred in 39% BN/AMA+ and 49% PBC patients. The frequency of BN/AMA+ with high probability of having established PBC increased from 7 to 14%. Conclusions BN/AMA+ individuals present an orchestrated increase in ELF score and humoral autoimmune response over time, indicating an opportunity for early therapeutic intervention and prevention in autoimmunity.

Abstract Background: Preeclampsia prediction improves maternal and fetal outcomes in pregnancy. We aimed to evaluate the preeclampsia prediction values of a series of serum biomarkers. Methods: Singleton pregnant women with preeclampsia-related clinical and/or laboratory presentations were recruited and had blood drawn at their first visits. The prospective cohort was further divided into preeclampsia-positive and preeclampsia-negative groups based on the follow-up results. The following markers were tested using the collected serum samples: soluble fms-like tyrosine kinase-1 ( sFlt-1); placental growth factor (PlGF); thrombomodulin (TM); tissue plasminogen activator inhibitor complex (tPAI-C); compliment factors C1q, B, and H; glycosylated fibronectin (GlyFn); pregnancy-associated plasma protein-A2 ( PAPP-A2); blood urea nitrogen (BUN); creatinine (Cre); uric acid (UA); and cystatin C (Cysc). Results: A total of 196 women with suspected preeclampsia were recruited with follow-up medical records. Twenty-five percent (n=49) of the recruited subjects developed preeclampsia before delivery, and 75% remained preeclampsia-negative (n=147). The serum levels of sFlt-1, BUN, Cre, UA, Cysc and PAPP-A2 were significantly elevated, and the PlGF level was significantly decreased in the preeclampsia-positive patients. In the receiver operating characteristics (ROC) analyses, the area under the curves were listed in the order of decreasing values: 0.73 (UA), 0.67 (sFlt-1/PlGF), 0.66 (Cysc), 0.65 (GlyFn/PlGF), 0.64 (PAPP-A2/PlGF), 0.63 (BUN), 0.63 (Cre), and 0.60 (PAPP-A2). With the cut-off values obtained from the ROC analyses, the positive predictive values of these serum markers were between 33.1% and 58.5%, and the negative predictive values were between 80.9% and 89.5%. Conclusions: Further studies are warranted to confirm the clinical utilities of the serum markers in preeclampsia prediction

Background: Bone morphogenetic proteins-2 and -4 (BMPs) have been implicated in left ventricular remodeling (LVR) processes such as an inflammation and fibrogenesis. We hypothesized that this knowledge could be translated into clinics. Methods: We studied the dynamics of serum levels of BMPs, its correlation with markers of LVR and with parameters of echocardiography in patients (n = 31) during the six-month follow-up period after myocardial infarction (MI). Results: Elevated serum levels of BMPs decreased by the six-month follow-up period. BMP-2 decreased from the first day after MI, and BMP-4 decreased from the Day 14. The elevated level of BMP-2 at Day 1 was associated with a lower level of troponin I, reperfusion time and better left ventricular ejection fraction (LV EF) at the six-month follow-up. Elevated serum level of BMP-4 at Day 1 was associated with a lower level of a soluble isoform of suppression of tumorigenicity 2 (sST2), age and reperfusion time. An elevated level of BMP-2 at the six-month follow-up was associated with higher levels of BMP-4, high-sensitivity C-reactive protein (hCRP) and sST2. High serum level of BMP-2 correlated with high levels of hCRP and matrix metalloproteinase (MMP)-9 on Day 7. High serum level of BMP-4 correlated with low levels of hCRP, MMP-9 at Day 3, sST2 at Day 1 and with decreased LV EF on Day 7. The findings of multivariate analysis support the involvement of BMP-2 in the development of post-infarction LVR. Conclusions: Our research translates experimental data about the BMPs in the development of adverse LVR into the clinic. Elevated serum levels of BMPs decreased by the end of the six-month period after MI. BMP-2 decreased from the first day and BMP-4 decreased from Day 14. BMP-2 and BMP-4 were associated with the development of LVR. Their correlations with markers of inflammation, degradation of the extracellular matrix, hemodynamic stress and markers of myocardial damage further support our hypothesis. Diagnostic and predictive values of these BMPs at the development of post-infarction LVR in vivo should be investigated further.

Background: Elevated serum aminotransferase levels are commonly associated with obesity and with a progression to chronic liver disease. Bariatric surgery is the most effective strategy to achieve weight loss. Methods: We conducted the present study with the aim of evaluating the influence of biliopancreatic diversion (BPD) on liver enzymes levels during 4 years in morbid obese patients with normal aminotransferase (n = 65) and in morbid obese patients with high aminotransferase basal levels (n = 50). Results: A decrease in alanine aminotransferase and aspartate aminotransferase activities was significant after biliopancreatic diversion. The basal percentage of high aminotransferase levels and percentage of ratio ALT/AST <1 also decreased significantly at 1-, 2-, 3- and 4-years of follow-up in both groups. ALT (52 to 20%), AST (42 to 10%) and ALT/AST (80 to 22%) in patients with normal aminotransferase. ALT (82 to 20%), AST (70 to 6%) and ALT/AST (90 to 20%) in patients with elevated transaminase basal levels. Bariatric surgery was associated with a significant and sustained decrease in body weight in both groups. Serum trasnaminases level changes were positively correlated to body weight changes during follow-up. Conclusion: BPD is an effective method of achieving sustainable weight loss and reduced aminotransferase levels and enzyme ratios of liver damage.

Background. Intrauterine environment plays a pivotal role in the origin of fatal diseases such as diabetes. Diabetes and obesity are associated with low-grade inflammatory state and dysregulated adipokines production. This study aims to investigate the effect of maternal obesity and malnutrition on adipokines production (adiponectin, leptin, and TNF-α) in F1 offspring in rats.Materials and Methods. Wistar rats were allocated in groups: F1 offspring of control mothers under control diet (CF1-CD) and under high-fat diet (CF1-HCD), F1 offspring of obese mothers under CD (OF1-CD) and under HCD (OF1-HCD), and F1 offspring of malnourished mothers under CD (MF1-CD) and under HCD (MF1-HCD). Every 5 weeks postnatally, blood samples were obtained for biochemical analysis.Results. At the end of the 30-week follow-up, OF1-HCD and MF1-HCD exhibited hyperinsulinemia, moderate dyslipidemia, insulin resistance, and impaired glucose homeostasis compared to CF1-CD and CF1-HCD. OF1-HCD and MF1-HCD demonstrated low serum levels of adiponectin and high levels of leptin compared to CF1-CD and CF1-HCD. OF1-CD, OF1-HCD, and MF1-HCD had elevated serum levels of TNF-αcompared to CF1-CD and CF1-HCD (p<0.05).Conclusion. Maternal nutritional manipulation predisposes the offspring to development of insulin resistance in their adult life, probably via instigating dysregulated adipokines production.

AbstractSerum Krebs von den Lungen-6 (KL-6) is clinically used for the diagnosis of interstitial pneumonia (IP) as well as the evaluation of its disease activity. A female patient was diagnosed with idiopathic IP when she was 62 years old. Four years later, serum levels of KL-6 had been elevated gradually from 2400–3821 U/ml, and she was found to have gallbladder cancer detected by contrast-enhanced computed tomography (CT) and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/CT. She thus underwent a radical extended cholecystectomy. After the operation, serum levels of KL-6 showed a steep decline to 590 U/ml. Immunohistological examination revealed that KL-6 presented in gallbladder cancer cells. Taken together, serum KL-6 was shown to be produced by gallbladder cancer cells. Here, we present the first patient in whom increased serum KL-6 levels led to the diagnosis of gallbladder cancer during follow-up of IP. When serum levels of KL-6 are elevated during the follow-up care of IP despite no worsening of IP, an examination of the whole body should be performed to find possibly existing malignant tumors.
