Preeclampsia is a pregnancy-specific disease of high prevalence characterized by the onset of hypertension, among other maternal or fetal signs. Its etiopathogenesis remains elusive, but it is widely accepted that abnormal placentation results in the release of soluble factors that cause the clinical manifestations of the disease. An increased level of soluble endoglin (sEng) in plasma has been proposed to be an early diagnostic and prognostic biomarker of this disease. A pathogenic function of sEng involving hypertension has also been reported in several animal models with high levels of plasma sEng not directly dependent on pregnancy. The aim of this work was to study the functional effect of high plasma levels of sEng in the pathophysiology of preeclampsia in a model of pregnant mice, in which the levels of sEng in the maternal blood during pregnancy replicate the conditions of human preeclampsia. Our results show that wild type pregnant mice carrying human sEng-expressing transgenic fetuses (fWT(hsEng+)) present high plasma levels of sEng with a timing profile similar to that of human preeclampsia. High plasma levels of human sEng (hsEng) are associated with hypertension, proteinuria, fetal growth restriction, and the release of soluble factors to maternal plasma. In addition, fWT(hsEng+) mice also present placental alterations comparable to those caused by the poor remodeling of the spiral arteries characteristic of preeclampsia. In vitro and ex vivo experiments, performed in a human trophoblast cell line and human placental explants, show that sEng interferes with trophoblast invasion and the associated pseudovasculogenesis, a process by which cytotrophoblasts switch from an epithelial to an endothelial phenotype, both events being related to remodeling of the spiral arteries. Our findings provide a novel and useful animal model for future research in preeclampsia and reveal a much more relevant role of sEng in preeclampsia than initially proposed.

Abstract Aims To determine whether plasma apoE levels and APOE genotype are associated with all-cause and cause-specific mortality. Methods and results Using a prospective cohort design with 105 949 white individuals from the general population, we tested the association between plasma apoE at study enrolment and death during follow-up, and whether this was independent of APOE genotype. We confirmed the well-known association between APOE genotypes and mortality. For all-cause, cardiovascular, and cancer mortality, high levels of apoE were associated with increased risk, while for dementia-associated mortality low levels were associated with increased risk. For the highest vs. the fifth septile of plasma apoE, hazard ratios (HRs) were 1.20 (95% confidence interval 1.12–1.28) for all-cause mortality, 1.28 (1.13–1.44) for cardiovascular mortality, and 1.18 (1.05–1.32) for cancer mortality. Conversely, for the lowest vs. the fifth septile the HR was 1.44 (1.01–2.05) for dementia-associated mortality. Results were similar in analyses restricted to APOE ɛ33 carriers. Examining genetically determined plasma apoE, a 1 mg/dL increase conferred risk ratios of 0.97 (0.92–1.03) for cardiovascular mortality and 1.01 (0.95–1.06) for cancer mortality, while a 1 mg/dL decrease conferred a risk ratio of 1.70 (1.36–2.12) for dementia-associated mortality. Conclusion High plasma levels of apoE were associated with increased all-cause, cardiovascular, and cancer mortality, however of a non-causal nature, while low levels were causally associated with increased dementia-associated mortality.

Adrenalectomized Rats

The effects of high plasma renin levels on plasma levels of both total immunoreactive angiotensinogen (direct radioimmunoassay) and intact angiotensinogen measured by angiotensin I released by renin (indirect assay) were studied in sodium-depleted rats both with and without captopril treatment and in adrenalectomized rats. The direct assay measures both intact angiotensinogen and des-angiotensin I-angiotensinogen, its residue cleaved by renin. The indirect assay measures only intact angiotensinogen. Neither sodium depletion, captopril treatment, nor adrenalectomy modified the circulating levels of total angiotensinogen. However these treatments produced a decrease in intact angiotensinogen that was in proportion to the elevation of renin levels. The difference between the two assays for angiotensin represents the level of des-angiotensin I-angiotensinogen and correlated satisfactorily with the plasma levels of renin. Identical correlations were observed in adrenalectomized rats and captopril-treated rats. We conclude that des-angiotensin I-angiotensinogen levels are an index of activation of the renin-angiotensin system dependent on the circulating level of renin.

Twenty-four hemodialysis patients, 14 with uremic neuropathy and 10 symptom-free, were studied over 12 months. Cuprophan and AN 69 membrane dialyzers were used in their treatment in order to investigate the influence of different membranes on plasma levels of middle molecular weight substances (MMS) and uremic neuropathy. Hemodialysis with the cuprophan membrane caused no significant changes in plasma MMS levels or in the neurological condition of patients. The effect of dialysis with AN 69 membrane depended on initial plasma MMS levels. Initially high plasma MMS levels decreased significantly and significant improvement of neuropathy was achieved. In neuropathic patients with plasma MMS levels similar to those of symptom-free patients, hemodialysis with AN 69 membrane had no effect. These results suggest that hemodialysis with MMS high-permeability membranes may be recommended for neuropathic patients with high plasma MMS levels.

Pre Treatment

Jugular blood samples were obtained from 10.5 kg and 28 kg lambs receiving a diet of reconstituted cows' whole milk. The lambs were then given diets in which the proportion of essential amino acids (BAA) in the dietary crude protein was altered over a wide range. A second blood sample was taken after lambs had received such diets for 12 days. Plasma obtained from these samples was analysed for free amino acids, urea and ammonia. The pattern of plasma free amino acids (PFAA) in lambs given reconstituted cows' whole milk is described. In both the pre-treatment and post-treatment samples, the heavier lambs appeared to have lower plasma levels of all EAA, and high plasma levels of glycine, serine, urea and ammonia. In the lighter lambs, there were pronounced responses of PFAA levels to changes in the dietary proportion of EAA. At low proportions, the levels of most EAA in plasma were low. Lysine and phenylalanine were exceptions. In addition, levels of many non-essential amino acids (non-EAA), particularly serine and glycine, were high. At high proportions of EAA, plasma levels of all EAA, especially methionine, rose markedly. Within the non-EAA, serine, proline and glycine were reduced, while taurine and cystathionine increased. In the plasma of the heavier lambs, the response of some amino acids to a given dietary change differed from the response in the lighter lambs. This was especially true of methionine, tyrosine, phenylalanine and arginine. There was also marked between-animal variation in plasma levels. When expressed as molar proportions of total PFAA, results were similar to those of the lighter lambs. There was a pronounced similarity between the response of the PFAA to diets with a low proportion of EAA, and the PFAA pattern characteristic of developing kwashiorkor. __________________ *Part II, Aust.

The Relationship

BackgroundThe appropriate balance between anti-inflammatory and pro-inflammatory cytokines is necessary for protection against pregnancy-associated malaria and poor pregnancy outcomes. This study therefore aims to investigate the relationship between plasma levels of some regulatory cytokines and P. falciparum infection in Cameroonian women during pregnancy.MethodsPeripheral blood was collected from 131 women during pregnancy and 27 non-pregnant women living in the Mbalmayo area between May and December 2014. Parasitaemia was determined by microscopy and haemoglobin level using a haematological counter. Plasma levels of IL-27 and IL-6 cytokines were measured using the Magnetic Luminex Screening Assay technique.ResultsParasitaemia associated negatively with haemoglobin level (rs=–0.43; p<0.001). The plasma level of IL-6 was higher in pregnant women than in non-pregnant women (p=0.05). Regarding parasitaemia, plasma level of IL-27 was significantly higher in non-infected than in infected women (p=0.028) while that of IL-6 was significantly higher in infected women (p<0.0001). Moreover, parasitaemia correlated negatively with the plasma level of IL-27 (p=0.034) and positively with that of IL-6 (p<0.0001). In addition, level of IL-6 was significantly higher in anaemia-positive than in anaemia-negative women (p=0.028). On the other hand, level of IL-27 negatively associated with the parity (p=0.022) and gestation age (p=0.014).ConclusionThese results show that in pregnant women, P. falciparum malaria infection is associated with high plasma level of IL-6 and low level of IL-27, suggesting that IL-27 could have a protective effect against pregnancy-associated malaria while IL-6 seem to be a potential biomarker of the disease.
