Aim. This study was designed to clarify the role of leptin and adiponectin in preeclampsia (PE) pathogenesis and different subtypes of preeclampsia.Method. This case control study was performed in 45 PE patients and 45 healthy controls matched for age, BMI, and ethnicity. Serum leptin and adiponectin levels were determined by enzyme linked immunosorbent assay (ELISA).Results. Maternal serum leptin and adiponectin were significantly higher in PE women than controls. Serum leptin was elevated in early onset preeclampsia (EOPE) and late onset preeclampsia (LOPE) compared to controls. Among PE patients, serum leptin was higher in EOPE than LOPE women. However, serum adiponectin was not different between EOPE and LOPE women. The serum leptin was significantly higher in severe PE than mild PE. The serum adiponectin was significantly elevated in severe PE compared to controls. Significant positive correlation was observed between leptin and adiponectin and also between leptin and BMI in controls. Moreover significant positive correlation was observed between adiponectin and BMI in PE patients and controls.Conclusion. The present study showed that serum leptin level may play a significant role as a biomarker to differentiate early and late onset PE and also its relation to BMI and severity of disease.

Objective. The aim of this study was to determine whether maternal serum matrix metalloproteinases 2, 3, 9, and 13 levels differ in early- and late-onset preeclampsia and uncomplicated pregnancies. Patients and Methods. The study was carried out in 125 pregnant women (29 with early-onset preeclampsia; 31 preeclamptic patients with late-onset preeclampsia; and 65 healthy pregnant controls). Levels of MMP-2, MMP-3, MMP-9, and MMP-13 were measured in the maternal serum using an enzyme-linked immunosorbent assay. Results. Maternal serum MMP-2 levels in both the groups of preeclamptic women were significantly higher than those in the controls. Levels of MMP-3 were significantly higher in preeclamptic patients with early-onset disease; however, the MMP-3 levels in patients with late-onset preeclampsia were similar to those observed in the control subjects. MMP-9 levels were lower whereas the levels of MMP-13 were higher in both preeclamptic groups of pregnant women than in the healthy controls, but these differences were statistically insignificant. Conclusions. One important finding of the present study was that MMP-3 appears to be involved solely in early-onset preeclampsia, but not in late-onset preeclampsia. Higher levels of MMP-2 and MMP-13 and lower levels of MMP-9 seem to be related to both early- and late-onset severe preeclampsia.

Early Onset Preeclampsia

Early Onset Preeclampsia (EO-PE) is preeclampsia that develops before 34 weeks 'gestation, caused by intrinsic factors, while Late Onset Preeclampsia (LO-PE) is preeclampsia that develops after 34 weeks' gestation due to extrinsic and maternal factors. There is an increased production of antiangiogenic factors (sFlt-1, s-Eng and PIGF) contribute to pathophysiology of preeclampsia.This study aims to measure the difference of sFlt-1, sEng, PIGF levels between EO-PE and LO-PE. This was an observational study with cross sectional design conducted at Dr. M. Djamil, TK Hospital. III dr. Reksodiwiryo and Biomedical Laboratory FK Unand Padang from August 2017 to August 2018. The sample of this study were 26 severe preeclampsia women : 13 (EO-PE)  and 13 (LO-PE), selected using consecutive sampling. Levels of sFlt-1, sEng, PIGF were examined using the enzyme-linked immunosorbent assay (ELISA) method. Statistical analysis was performed using unpaired t test and Mann-Whitney Test. Results shown that serum levels of sFlt-1 and sEng in (EO-PE)  were 9.51 ± 0.71 ng / L, 1.44 ± 0.06 ng / mL, 5.79 ± 0.42 ng / mL while in PEAL it was 8, 89 ± 0.78 ng / mL, 1.35 ± 0.14 ng / mL, 6.72 ± 0.76. There were a significant difference with a value of p <0.05. The conclusion of this study is that the levels of sFlt-1 and sEng are higher in (EO-PE)  than(LO-PE)and PIGF levels was lower in (EO-PE) compared to (LO-PE)

Matrix Metalloproteinases 14 presumably play for cytotrophoblast migration and invasion of the uterine wall and in the remodeling of the spiral arteries in pregnancy. Inadequate trophoblastic invasion leads to an inappropriate vascular remodeling, which generates conditions of hypoxia and increased oxidative stress in the placenta early onset preeclampsia. Therefore, it is particularly important to investigating whether MMP14 altered and can be used as biomarker of preeclampsia. There have been no studies done to measure MMP14 in serum maternal between early onset preeclampsia and normal pregnancy The purpose of this study was to analyse whether maternal serum matrix metalloproteinases 14 levels differ in early onset preeclampsia and uncomplicated pregnancies. This crosssectional study was carried out in 20 subjects with early onset preeclampsia and 20 subjects of normotensive pregnant women range 24 up to 34 weeks of gestation. The study was conducted in Margono Hospital Purwokerto, Indonesia. Level of MMP 14 was measured in maternal serum using an enzyme-linked immunosorbent assay (ELISA). The mean difference was statically analysed by independent samples T-test and ROC curve to determine sensitivity and specificity of MMP 14.Women age, gestational age, parity and body mass index showed a non significant difference between both groups. In this study level MMP 14 in serum was higher in pregnant women with preeclampsia compared to the normotensive ( 266.41 vs 46.80 pg/dl ; p<0.00). Moreover, the area under curve of serum MMP 14 was 0.936, standard error 0.043, p<0.00. The optimal cut-off value of serum MMP at 110.73 pg/dl showed a high diagnostic value in preeclampsia with a sensitivity of 90 % and a specificity of 90%. Maternal serum MMP 14 was higher in preeclampsia and the important finding is the MMP 14 probably become a marker to predict early onset preeclampsia.

Early Onset Preeclampsia

Background: Many studies had discovered that early onset severe preeclampsia (EO-PE) has worst maternal and neonatal outcome compared to late-onset type (LO-PE), related to its placental involvement. Severe preeclampsia was defined as newly onset severe hypertension developed after 20 weeks gestation in previously normal blood pressure women, with coexistence of proteinuria, or maternal organ or uteroplacental dysfunction. Hemeoxygenase-1 (HO-1) is an enzyme with multiple effect which is protective to pregnancy.Materials and Methods: The total study subjects were 40 pregnant women consisted of 10 EO-PE, 10 normal early onset pregnancy (EO-NP), 10 LO-PE, and 10 normal late onset pregnancy (LO-NP). As much as 5 cc of plasma from umbilical cord was taken as soon as the baby was born, and the HO-1 level was examined by enzyme-linked immunosorbent assay (ELISA). The primary outcome were umbilical cord HO-1 level and neonatal composite morbidity (low Apgar score, low birthweight, length of stay >5 day, respiratory distress syndrome, jaundice and neonatal death).Results: The plasma level of HO-1 in EO-PE subjects were lower than EO-NP (0.96±0.37 ng/mL vs. 2.43±0.58 ng/mL, p<0.001). There were no significant differences in the level of HO-1 in LO-PE and LO-NP (2.18±1.07 ng/mL vs. 3.02±0.64 ng/mL, p=0.277). Plasma level of umbilical cord HO-1 of EO-PE patients was lower compared to LO-PE (0.96±0.37 ng/mL vs. 2.18±1.07 ng/mL, p=0.034). Neonatal outcome of EO-PE was worse than EO-NP (p=0.033), and LO-PE (p=0.003), while in LO-PE did not different with LO-NP (p=0.211).Conclusion: EO-PE is associated with lower plasma umbilical cord level of HO-1 and worse neonatal outcome compared to LO-PE. This indicating abnormal placental blood vessel development, placental ischemia in EO-PE, lead to reduced uteroplacental perfusion and significantly worse neonatal outcome compared to LO-PE.Keywords: severe preeclampsia, early onset preeclampsia, late onset preeclampsia, hemeoxygenase-1

BACKGROUND: Preeclampsia can be divided into early (EOPE) and late (LOPE) onset preeclampsia. Preeclampsia is related to the failure of placentation. Accumulation of hypoxia-inducible factors (HIF)-1α is commonly an acute and beneficial respond to hypoxia, while chronically elevated is associated with preeclampsia. AIM: This study aims to evaluate the serum levels of HIF-1α in preeclampsia and normal pregnancy, and to compare the difference between early-onset and late-onset preeclampsia. METHODS: A cross-sectional comparative study was conducted among a total of 69 pregnant women at ≥ 20 weeks of gestation, were recruited at obstetrics and gynaecology department at Dr M. Djamil Padang Hospital, network hospitals, health centres. They were divided into three groups early-onset preeclampsia, late-onset preeclampsia, and normal pregnancy. Preeclampsia was diagnosed using International Guidelines. Data were analysed by SPSS 24 program; data are presented as median and range or as mean ± standard deviation. One-way ANOVA test was used to determine the relationship between HIF-1α levels with the onset of preeclampsia. RESULTS: The results showed that the mean maternal serum HIF-1α levels in early-onset preeclampsia (EOPE), late-onset preeclampsia (LOPE), and normal pregnancy were 1366.96 ± 733.40 pg/ml, 916.87 ± 466.06 pg/ml, and 716.77 ± 541.08 pg/ml. Serum HIF-1α levels were higher in early-onset preeclampsia (EOPE), and late-onset preeclampsia (LOPE) compared to normal pregnancy. Among preeclampsia patients, serum HIF-1α was higher in EOPE than LOPE women. Statistical analysis revealed a significant difference in mean maternal serum HIF-1α between early-onset preeclampsia, late-onset preeclampsia, and normal pregnancy (p < 0.05). CONCLUSION: This study concluded that there is a significantly different level of HIF-1α between in early-onset preeclampsia, late-onset preeclampsia and normal pregnancy. Early-onset preeclampsia is the highest levels of serum HIF-1α.

BACKGROUND Preeclampsia is affected by oxidative stress, a free-radical produced as a by-product of endothelial damage, and antioxidant imbalance, such as vitamin D₃. This study was aimed to compare the vitamin D₃ levels in the placenta, cord blood, and maternal serum between patients with and without preeclampsia.  METHODS This cross-sectional study included 86 patients from Cipto Mangunkusumo Hospital and Tangerang District Hospital, in which 47 had preeclampsia (13 early-onset and 16 late-onset preeclampsia cases) and 39 had no preeclampsia. The placenta, cord blood, and maternal serum were taken after labor, then were analyzed according to preeclampsia and non-preeclampsia; furthermore, the preeclampsia group was analyzed in a subgroup of early- and late-onset preeclampsia. This is analyzed with either unpaired t-test, Mann–Whitney U test, or Kruskal–Wallis test.  RESULTS The maternal serum, cord blood, and placental tissue vitamin D₃ levels (16.30 [6.20–49.00], 11.80 [3.50–38.60], and 49.00 [22.00–411.00] ng/ml, respectively) of the preeclampsia group were similar to those of the non-preeclampsia group (13.50 [4.80– 29.20], 11.70 [1.00–28.80], and 43.40 [11.80–153.00] ng/ml, respectively) (p = 0.459, 0.964, and 0.354, respectively). However, the placental tissue vitamin D₃ levels in early-onset preeclampsia (79.00 [36.00–411.00] ng/ml) were higher than those in late-onset preeclampsia (40.00 [22.00–171.00] ng/ml) (p = 0.006).  CONCLUSIONS The vitamin D₃ levels between patients with and without preeclampsia were similar. However, the placental tissue vitamin D₃ levels in early-onset preeclampsia were higher than those in late-onset preeclampsia, possibly because of the different pathophysiology between early- and late-onset preeclampsia.

: Alzheimer’s disease (AD) is a progressive brain disorder and one of the most common causes of dementia and death. AD can be of two types; early-onset and late-onset, where late-onset AD occurs sporadically while early-onset AD results from a mutation in any of the three genes that include amyloid precursor protein (APP), presenilin 1 (PSEN 1) and presenilin 2 (PSEN 2). Biologically, AD is defined by the presence of the distinct neuropathological profile that consists of the extracellular β-amyloid (Aβ) deposition in the form of diffuse neuritic plaques, intraneuronal neurofibrillary tangles (NFTs) and neuropil threads; in dystrophic neuritis, consisting of aggregated hyperphosphorylated tau protein. Elevated levels of (Aβ), total tau (t-tau) and phosphorylated tau (ptau) in cerebrospinal fluid (CSF) have become an important biomarker for the identification of this neurodegenerative disease. The aggregation of Aβ peptide derived from amyloid precursor protein initiates a series of events that involve inflammation, tau hyperphosphorylation and its deposition, in addition to synaptic dysfunction and neurodegeneration, ultimately resulting in dementia. The current review focuses on the role of proteomes in the pathogenesis of AD.

AbstractAbnormal maternal serum biomarkers (AMSB), identified through the aneuploidy screening programme, are frequent incidental findings in pregnancy. They are associated with fetal growth restriction (FGR), but previous studies have not examined whether this association is with early-onset (< 34 weeks) or late-onset (> 34 weeks) FGR; as a result there is no consensus on management. The aims of this study were to determine the prevalence and phenotype of FGR in women with AMSB and test the predictive value of placental sonographic screening to predict early-onset FGR. 1196 pregnant women with AMSB underwent a 21–24 week “placental screen” comprising fetal and placental size, and uterine artery Doppler. Multivariable regression was used to calculate a predictive model for early-onset FGR (birthweight centile < 3rd/< 10th with absent umbilical end-diastolic flow, < 34 weeks). FGR prevalence was high (10.3%), however early-onset FGR was uncommon (2.3%). Placental screening effectively identified early-onset (area under the curve (AUC) 0.93, 95% confidence interval (CI) 0.87–1.00), but not late-onset FGR (AUC 0.70, 95% CI 0.64–0.75). Internal validation demonstrated robust performance for detection/exclusion of early-onset FGR. In this cohort, utilisation of our proposed algorithm with targeted fetal growth and Doppler surveillance, compared with universal comprehensive surveillance would have avoided 1044 scans, potentiating significant cost-saving for maternity services.

AbstractThe presence of circulating immune complexes (CIC) in the sera of dogs infected with Dirofilaria immitis was detected by using a Clq-binding enzyme-linked immunosorbent assay. Specificity of this assay with different concentrations of heat-aggravated canine IgG (ACG) was observed, i.e., the ELISA readings, expressed as ug equivalents ACG/ml, increased with increasing amounts of ACG. The intra-assay variability was below 10%. The CIC levels of infected and uninfected dogs were 177–0± 104–7 ug/ml and 22–8±45–8 ng/ml (mean±SD), respectively. The highest level was observed in 12 dogs with amicrofilaraemic infection. Age distribution of CIC levels in the 23 infected dogs also showed a significant positive correlation. These findings suggested that the CIC are present in the sera of dogs with dirofilariasis and may relate to canine glomerulonephritis.
