MAST1-related mega-corpus-callosum syndrome with central hypogonadism.

OBJECTIVE: Heterozygous variations in microtubule-associated serine/threonine kinase 1 gene (MAST1) were recently described in the mega-corpus-callosum syndrome with cerebellar hypoplasia and cortical malformations (MCCCHCM, MIM 618273), revealing the importance of the MAST genes family in global brain development. To date, patients with MAST1 gene mutations were mostly young children with central nervous system involvement, impaired motor function, speech delay, and brain magnetic resonance imaging (MRI) abnormalities. Here, we report the clinical presentation of an adult patient with a rare and de novo MAST1 mutation with central hypogonadism that could extend this phenotype. METHODS: A panel of 333 genes involved in epilepsy or cortical development was sequenced in the described patient. Routine biochemical analyses were performed, and hormonal status was investigated. RESULT: We report a 22-year-old man with a de novo, heterozygous missense variant in MAST1 (Chr19(GRCh37):g.12975903G > A, NP_055790.1:p.Gly517Ser). He presented with an epileptic encephalopathy associated with cerebral malformations, short stature, hypogonadotropic hypogonadism, and secondary osteopenia. CONCLUSION: This is the first patient with MAST1 gene mutation described with central hypogonadism, which may be associated with the phenotype of MCCCHCM syndrome.

[Care pathways for young transgender people]. / Parcours de soins des jeunes personnes transgenres.

Gender incongruence corresponds to the mismatch between gender identity and gender/sex assigned at birth gender/sex assigned at birth. It can be accompanied by psychological distress. In line with the literature, an increase in consultations for gender incongruence has been observed, especially among young people. Multidisciplinary care should be offered to this population; here we provide an example of healthcare proposed at the university hospital of Nancy.

[Using simulation for assessment: the example of OSCE in medical students]. / La simulation pour les évaluations : l'exemple des Ecos chez les étudiants en médecine.

Training of health sciences students is based on the acquisition of clinical skills. Tools assessing the application of theoretical knowledge through written examinations or the tools evaluating student's performance at patient bedsides are characterized by a low reliability. The Objective Structured Clinical Examination (OSCE) was developed to address the lack of reliability and standardization of traditional forms of the assessment of clinical performance.

e-Health Literacy Skills in People with Chronic Diseases and What Do the Measurements Tell Us: A Scoping Review.

Background: Use of electronic health (e-Health) technologies has increased in the past decade and inadequate e-Health literacy may lead to health-related social inequality. This is especially true for patients living with chronic diseases who are often involved in self-care. However, the measurement of e-Health literacy represents several challenges. Among available instruments, the e-Health Literacy Scale (eHEALS) is the only instrument with available psychometric properties. Aim: To identify studies measuring e-Health literacy in adults living with chronic disease and its relationship to health-related behaviors and other perceptions such as quality of life, self-efficacy, or specific disease biomarkers, and studies analyzing the impact of educational intervention on e-Health literacy. Methods: The authors searched MEDLINE, the Cochrane Library, and Web of Science databases to identify studies published in English language until April 2022. Results: Seventeen studies involving 4,877 participants were included. A majority of the studies were cross-sectional with a lack of appropriate controls. Five of the included studies were experimental, involving 758 participants. All of them reported positive effects of educational interventions on the improvements in self-reported e-Health literacy skills. However, most studies were at risk of bias. Conclusion: Despite these limitations, the findings of this review indicate the positive relationship between e-Health literacy and various health care processes in adults with chronic diseases and highlights a need for prospective controlled studies. Promoting e-Health literacy might give better opportunities for the active involvement of people with chronic diseases in self-care and for the implementation of online interventions into existing system of care.

User-centered approach in the development of an eHealth tool for self-management skills in functional insulin therapy to prevent complications of diabetes.

One of the biggest tasks for health professionals is to address the needs of persons with chronic illnesses like type 1 diabetes (T1D) and to support the acquisition of all necessary self-management behaviors. Functional insulin therapy (FIT) enables patients to adapt insulin doses according to everyday situations and reduces the risk of complications of diabetes. The aim was to describe the co-development, with patient as partners, of an eHealth tool for the acquisition of skills in FIT, to evaluate the user's acceptability and learning effectiveness on a sample of T1D patients followed in the University Hospital of Nancy. Subjects were invited to participate between July and August 2020. A total of 35 participants from different professional categories, median age of 41 years (IQR 27; 60) were included. In 22 subjects having access to all learning activities, there were positive relationships between the success score and the task (Spearman's rank correlation coefficient rs = 0.5), between the intent to use and following parameters: perceived utility (rs = 0.694), educational adequacy (rs = 0.786), tasks rs = (0.664), technology (rs = 0.520) and ease of use (rs = 0.659). This pilot study describes a user-centered approach to development of an eHealth tool for the acquisition of self-management skills in FIT. The online tool was well accepted and showed a positive impact on learning. The concept presented here will be useful to prompt future eHealth interventions in T1D or other chronic conditions aiming to increase patients' autonomy to prevent disease-related complications.

Adverse effects of gender-affirming hormonal therapy in transgender persons: Assessing reports in the French pharmacovigilance database.

Limited data are available on adverse drug reactions (ADRs) of gender-affirming hormone therapy (HT), mainly due to the lack of population-based studies with adequate controls, thus making spontaneous reporting systems a valuable tool to detect potential side reactions. In this nationwide retrospective study, we aimed to analyze ADRs related to gender-affirming HT reported in the French pharmacovigilance database (FPVD). We requested all the individual case safety reports related to gender-affirming HT recorded in the FPVD before May 27, 2020. We excluded previously published cases and those where gender-affirming HT was not the suspected drug. A total of 28 reports of ADRs were identified. Six concerned transgender men (21-40 years) and 22 transgender women (22-68 years). In transgender men taking testosterone enanthate, all reported ADRs were cardiovascular events, with pulmonary embolism in 50% of cases. Median time to onset (TTO) was 34 months. In transgender women, antiandrogens, mainly cyproterone acetate, were involved in 68% of cases, and estrogens in 77% of cases, mostly in association with progestin or cyproterone acetate. Meningiomas were the principal ADRs, followed by cardiovascular events, with a median TTO of 5.3 months. Our data show a previously unreported, non-negligible proportion of cases indicating cardiovascular ADRs in transgender men younger than 40 years. In transgender women, cardiovascular events were the second most frequent ADR. Further research is necessary to identify risk factors that might help to the individualization of treatment strategies. There is a necessity to increase awareness, implement preventive and education measures.

Tutor-Student Partnership in Practice OSCE to Enhance Medical Education.

BACKGROUND: Training of examiners is essential to ensure the quality of objective structured clinical examination (OSCE). We aimed to study a perceived effectiveness of tutor-student partnership in a practice OSCE module by novice OSCE tutors and medical students. METHOD: We implemented a practice OSCE at a medical faculty in France with novice tutors and third year medical students as partners. Each tutor (n = 44) served as a partner for the group of 5 students in the conception of the scenario and as an evaluator of the tutored station. Students (n = 303) were involved in the conception of a case and the roles of a physician, evaluator and a simulated patient. Data were obtained through self-assessment questionnaires. Descriptive statistics were used to analyze items of the questionnaires. Free-form answers were coded and analyzed thematically. RESULTS: A total of 36 tutors (82%) and 185 students (61%) responded to the questionnaires. The intervention was well perceived. Thirty-two percent of the tutors reported some difficulties in the assessment of student performance and were disposed to receive further training. Fifty-five percent of the students considered the participation in the OSCE case development appropriate to their level of knowledge, and 70% perceived it as beneficial allowing them to set their learning goals. CONCLUSION: This initiative provides a relevant method beneficial to OSCE tutors, medical students, and the faculty. Tutors learn how to assess student performance according to expected achievement levels. It allows students to be engaged as partners in co-creation of learning and teaching.

E-health education interventions on HbA1c in patients with type 1 diabetes on intensive insulin therapy: A systematic review and meta-analysis of randomized controlled trials.

AIMS: Patient-centered education improves glycemic control in subjects with type 1 diabetes (T1D). E-health technologies are widely used to support medical decision-making, patient advising or teleconsultations; however, the active participation of a patient is missing. Challenges remain whether e-health education can be effectively incorporated into clinical pathways. The purpose of the study was to examine the effects of e-health education, compared to standard care, on HbA1c. MATERIAL AND METHODS: We conducted a literature search (EMBASE, MEDLINE, The Cochrane Library and Web of Science) up to February 2018 for randomized controlled trials (RCTs) of Internet-/ mobile application-based educational interventions, with the active involvement of patients, provided in addition to, or substituting usual care in patients with T1D on intensive insulin therapy. The primary outcome was the standardized difference in means (SDM) of HbA1c change from baseline between intervention and comparator groups. RESULTS: Eight RCTs involving 757 subjects were included on 6335 screened citations. After excluding two trials with a high risk of bias from the meta-analysis, the HbA1c change from baseline did not significantly differ between intervention and comparator groups (SDM = -0.154, 95% CI: -0.335 to 0.025; P = 0.01, random-effect model). The number of studies is limited with a relatively short duration. Reporting of educational outcomes was not rigorous. CONCLUSIONS: The effect of e-health educational interventions on HbA1c in patients with T1D is comparable to the standard care. This review highlights the need for further well-designed RCTs that will investigate the opportunities of incorporating e-health education into clinical pathways.

Decrease in serum testosterone levels after short-term occupational exposure to diisononyl phthalate in male workers.

OBJECTIVE: The objective of the study was to examine the effects of occupational exposure to diisononyl phthalate (DINP) on serum testosterone levels in male workers. METHODS: From 2015 to 2018, 97 male workers were recruited from six French factories in the plastics industry. In a short longitudinal study, changes over 3 days in the level of total or free serum testosterone and DINP exposure were measured. DINP exposure was measured by urinary biomonitoring: mono-4-methyl-7-oxo-octyl phthalate (OXO-MINP), mono-4-methyl-7-hydroxy-octyl phthalate (OH-MINP) and mono-4-methyl-7-carboxyheptylphthalate (CX-MINP). We further analysed changes in follicle-stimulating hormone, luteinising hormone, total testosterone to oestradiol ratio and two bone turnover markers (procollagen-type-I-N propeptide, C terminal cross-linking telopeptide of type I collagen), and erectile dysfunction via standardised questionnaires (International Index of Erectile Function, Androgen Deficiency in Aging Males). Linear mixed models were used with the variables 'age' and 'abdominal diameter' included as confounder. RESULTS: Increased urinary OXO-MINP was associated with a significant decrease in total serum testosterone concentrations, but only for workers who exhibited the smallest variations and lowest exposures (p=0.002). The same pattern was observed for CX-MINP but was not significant; no association with OH-MINP was detectable. More self-reported erectile problems were found in workers exposed directly to DINP at the workstation (p=0.01). No changes were observed for the other biological parameters. CONCLUSIONS: Short-term exposure to DINP is associated with a decrease in total serum testosterone levels in male workers. Our results suggest that DINP could present weak antiandrogenic properties in humans, but these need to be confirmed by other studies.

Immunoglobulin Preparations Can Mislead Clinical Decision-Making in Follow-Up of Differentiated Thyroid Cancer.

OBJECTIVE: Intravenous and subcutaneous immunoglobulins are commonly used for immune substitution or as immune modulators in a variety of inflammatory and autoimmune disorders. Exogenous thyroid-specific thyroglobulin (Tg) antibodies present in the donor plasma may interfere with the interpretation of measurements of Tg autoantibodies (Tg-Abs) in the recipient's plasma and potentially trigger an immune response in the recipient's immune cells. Levels of antibodies causing bioassay interferences or those leading to clinically relevant changes in patient outcomes are not known. Tg is used as a biomarker in the long-term surveillance of patients with differentiated thyroid cancer (DTC) following total thyroidectomy and radioactive iodine ablation. However, the presence of Tg-Abs in the circulation interferes with Tg measurements. Assessment of levels of Tg-Abs is thus recommended as a part of standard follow-up of DTC together with Tg testing. METHODS: To understand the potential mechanisms and pathophysiologic significance of possible interferences associated with administration immunoglobulin preparations and Tg measurement, we overview the current knowledge on interactions between Tg autoimmunity and immunoglobulin preparations and illustrate diagnostic challenges and perspectives for follow-up of patients with DTC treated with exogenous immunoglobulins. RESULTS: In patients with DTC treated with immunoglobulin preparations, monitoring of thyroid cancer using Tg and Tg-Abs is challenging due to possible analytical interferences through passive transfer of exogenous antibodies from immunoglobulin preparations. CONCLUSION: Analytical interferences must be suspected when a discrepancy exists between clinical examination and diagnostic tests. Collaboration between endocrinologists, biologists, and pharmacologists is fundamental to avoid misdiagnosis and unnecessary medical or radiologic procedures. ABBREVIATIONS: CT = computed tomography; DTC = differentiated thyroid cancer; FNAB = fine-needle aspiration biopsy; HAb = heterophile antibody; IMA = immunometric assay; IVIg = intravenous immunoglobulin; RAI = radioactive iodine; RIA = radioimmunoassay; SCIg = subcutaneous immunoglobulin; Tg = thyroglobulin; Tg-Ab = thyroglobulin autoantibody; Tg-MS = thyroglobulin mass spectrometry; TPO-Ab = thyroid peroxidase autoantibody; TSHR-Ab = thyrotropin receptor autoantibody.

Fertility desires and reproductive needs of transgender people: Challenges and considerations for clinical practice.

The majority of transgender and gender nonconforming persons seeking medical care are of reproductive age. Hormonal treatment and sex reassignment surgery, which are used in the management of gender dysphoria, compromise fertility potential. Children and adolescents with gender dysphoria have specific treatment regimens starting with puberty-blocking medications. According to international guidelines, fertility preservation should be discussed before any hormonal treatment, although our knowledge on the reproductive needs of transgender and gender nonconforming persons is limited. Recently, some data have emerged on fertility management in some centres for the adult population with gender dysphoria. The goal of this review was to summarize the available evidence on the fertility desires and parental roles of transgender and gender nonconforming people. In light of newly emerging societal challenges, we aim to provide some considerations for clinical practice and suggest further areas of research.

Circulating Concentrations of Redox Biomarkers Do Not Improve the Prediction of Adverse Cardiovascular Events in Patients With Type 2 Diabetes Mellitus.

BACKGROUND: Despite pathophysiological relevance and promising experimental data, the usefulness of biomarkers of oxidative stress for cardiac risk prediction is unclear. The aim of our study was to investigate the prognostic value of 6 biomarkers exploring different pathways of oxidative stress for predicting adverse cardiovascular outcomes in patients with type 2 diabetes mellitus beyond established risk factors. METHODS AND RESULTS: The SURDIAGENE (Survie, Diabete de type 2 et Genetique) prospective cohort study consecutively recruited 1468 patients with type 2 diabetes mellitus. Assays were performed at baseline, and incident cases of major adverse cardiovascular events (MACE)-first occurrence of cardiovascular death, nonfatal myocardial infarction, or stroke-were recorded during a median of 64 months. Advanced oxidation protein products, oxidative hemolysis inhibition assay, ischemia-modified albumin, and total reductive capacity of plasma were not associated with the risk of MACE in univariate analyses. Fluorescent advanced glycation end products and carbonyls were associated with MACE (hazard ratio=1.38 per SD, 95% confidence interval 1.24-1.54, P<0.001 and hazard ratio=1.15 per SD, 95% confidence interval 1.04-1.27, P=0.006, respectively) in univariate analysis, but when added to a multivariate predictive model including traditional risk factors for MACE, these markers did not significantly improve c-statistics or integrated discrimination index of the model. CONCLUSIONS: These plasma concentrations of 6 markers, which cover a broad spectrum of oxidative processes, were not significantly associated with MACE occurrence and were not able to improve MACE risk discrimination and classification beyond classical risk factors in type 2 diabetes mellitus patients.

Plasma levels of hsa-miR-152-3p are associated with diabetic nephropathy in patients with type 2 diabetes.

Background: MicroRNAs (miRNAs) are small non-coding RNAs participating in post-transcriptional regulation of genes. Their key role in modulating the susceptibility to human diseases is now widely recognized, in particular in the context of cardiometabolic disorders. The aim of the present study was to identify miRNAs associated with diabetic nephropathy (DN) in patients with type 2 diabetes (T2D). Methods: A next-generation sequencing-based miRNA profiling was performed in a case-control study for DN in plasma samples of 23 T2D patients with DN (cases) and 23 T2D without (controls). The main associations were confirmed using quantitative reverse transcription-polymerase chain reaction and tested for replication in an independent case-control collection of 100 T2D patients, 50 with DN and 50 without. Results: From the 381 known mature miRNAs that were found highly expressed in the discovery samples, we observed and replicated an association between increased plasma levels of hsa-miR-152-3p and DN (P = 4.03 × 10-4 in the combined samples). Hsa-miR-152-3p plasma levels were further found to be positively correlated (P = 0.003) to plasma osmolarity, a surrogate marker for solute carrier net activity, whose regulation is controlled by several genes including SLC5A3, one of the predicted targets of hsa-miR-152-3p. Conclusions: We observed strong evidence for the association of hsa-miR-152-3p plasma levels and DN in patients with T2D, confirming an association previously observed in patients with type 1 diabetes.

Extracellular vesicles as immune mediators in response to kidney injury.

Important progress has been made on cytokine signaling in response to kidney injury in the past decade, especially cytokine signaling mediated by extracellular vesicles (EVs). For example, EVs released by injured renal tubular epithelial cells (TECs) can regulate intercellular communications and influence tissue recovery via both regulating the expression and transferring cytokines, growth factors, as well as other bioactive molecules at the site of injury. The effects of EVs on kidney tissue seem to vary depending on the sources of EVs; however, the literature data are often inconsistent. For example, in rodents EVs derived from mesenchymal stem cells (MSC-EVs) and endothelial progenitor cells (EPC-EVs) can have both beneficial and harmful effects on injured renal tissue. Caution is thus needed in the interpretation of these data as contradictory findings on EVs may not only be related to the origin of EVs, they can also be caused by the different methods used for EV isolation and the physiological and pathological states of the tissues/cells under which they were obtained. Here, we review and discuss our current understanding related to the immunomodulatory function of EVs in renal tubular repair in the hope of encouraging further investigations on mechanisms related to their antiinflammatory and reparative role to better define the therapeutic potential of EVs in renal diseases.

Post-transcriptional regulation of cytokine in the context of renal inflammation.

Mechanisms that control mammalian gene expression, notably mRNA stability and translation, have major functions in the modulation of the cellular response to internal and external stimuli. Altered posttranscriptional regulation of gene expression has been associated with many diseases. Such types of deregulation have also recently been noted on the inflammatory cytokines pertinent to kidney inflammation. In this article, we summarize briefly the recent knowledge obtained from both human and experimental systems on the details of posttranscriptional regulation of gene expression related to the control of mRNA stability and discuss their relevance in regulating cytokine expression linked to the inflammatory processes in kidney. Despite the fact that not many such examples in human kidney diseases have been uncovered with great mechanistic details, studies in experimental models suggest that the mRNA stability control is more than meets the eye. Therapeutic potentials aiming at regulating cytokine expression via posttranscriptional modification of mRNA half-life are thus discussed.

Cytokines in Endocrine Dysfunction of Plasma Cell Disorders.

Monoclonal gammopathies (MG) are classically associated with lytic bone lesions, hypercalcemia, anemia, and renal insufficiency. However, in some cases, symptoms of endocrine dysfunction are more prominent than these classical signs and misdiagnosis can thus be possible. This concerns especially the situation where the presence of M-protein is limited and the serum protein electrophoresis (sPEP) appears normal. To understand the origin of the endocrine symptoms associated with MG, we overview here the current knowledge on the complexity of interactions between cytokines and the endocrine system in MG and discuss the perspectives for both the diagnosis and treatments for this class of diseases. We also illustrate the role of major cytokines and growth factors such as IL-6, IL-1ß, TNF-α, and VEGF in the endocrine system, as these tumor-relevant signaling molecules not only help the clonal expansion and invasion of the tumor cells but also influence cellular metabolism through autocrine, paracrine, and endocrine mechanisms. We further discuss the broader impact of these tumor environment-derived molecules and proinflammatory state on systemic hormone signaling. The diagnostic challenges and clinical work-up are illustrated from the point of view of an endocrinologist.

Urinary lysophopholipids are increased in diabetic patients with nephropathy.

Diabetic nephropathy (DN) is a major cause of chronic kidney disease that frequently leads to end stage renal failure. Lysophosphatidic acid (LPA) and lysophosphatidylcholine (LPC) are lysophospholipid mediators shown to accumulate in kidney and to promote renal inflammation and tubulo-interstitial fibrosis in diabetic rodent models. Here we assessed whether LPA and LPC were associated to the development of nephropathy in diabetic human patients. Several molecular species of LPA and LPC were quantified by LC/MS-MS in urine and plasma from type 2 diabetic patients with (cases; n=41) or without (controls, n=41) nephropathy symptoms (micro/macro-albuminuria and eGFR<60ml/min/1.73m2). Cases and controls were matched for sex, age and diabetes duration. Six species were detected in urine for both LPA and LPC, LPA16:0, LPA20:4, LPC16:0, LPC18:0, LPC18:1, and LPC18:2 that were significantly more concentrated in cases than in controls. Total LPC and LPA (sum of detected species) were significantly and exclusively associated with albuminuria (P<0.0001 and P=0.0009 respectively) and were significantly higher in the 3rd when compared to the 1st albuminuria tertile in cases. Plasma lysophospholipids showed a different species profile urine and their concentrations were not different between cases and controls. In conclusion, urine concentration of lysophospholipids increases in diabetic patients with DN as the likely result of their co-excretion with albumin combined with possible local production by kidney. Because LPA and LPC are known to promote renal inflammation and tubulo-interstitial fibrosis, their increased production in DN could participate to the development of kidney damage associated with diabetes.

IL-6 signaling in diabetic nephropathy: From pathophysiology to therapeutic perspectives.

Diabetic nephropathy (DN) is a leading cause of chronic kidney disease (CKD). Interleukin-6 (IL-6) signaling participates in inflammation responses central to the progression of DN. Current evidence suggests that these IL-6 responses are mediated via gp130-STAT3 dependent mechanisms which, on one hand, trigger globally the transition from innate to adaptive immune response, and on the other hand act locally for tissue remodeling and immune cell infiltration. In diabetic conditions the role of IL-6 is not well elucidated. Both IL-6 classical signaling pathway via receptor IL-6R (IL-6R) and IL-6 trans-signaling pathway via soluble IL-6R (sIL-6R) were shown to participate in the pathogenesis and progression of DN, and IL-6 appears to influence renal cells also in an autocrine manner. To date, evidence is limited. The goal of this review is to provide an overview of our current understanding on the role of IL-6 signaling in DN and to delineate challenges for future research. Putative sequential events related to IL-6 secretion by different cell populations in diabetic conditions are outlined. Further, we discuss potential applications of anti-IL-6 therapy in the context of DN.

Role of post-transcriptional regulation of mRNA stability in renal pathophysiology: focus on chronic kidney disease.

Chronic kidney disease (CKD) represents an important public health problem. Its progression to end-stage renal disease is associated with increased morbidity and mortality. The determinants of renal function decline are not fully understood. Recent progress in the understanding of post-transcriptional regulation of mRNA stability has helped the identification of both the trans- and cis-acting elements of mRNA as potential markers and therapeutic targets for difficult-to-diagnose and -treat diseases, including CKDs such as diabetic nephropathy. Human antigen R (HuR), a trans-acting element of mRNA, is an RNA binding factor (RBF) best known for its ability to stabilize AU-rich-element-containing mRNAs. Deregulated HuR subcellular localization or expression occurs in a wide range of renal diseases, such as metabolic acidosis, ischemia, and fibrosis. Besides RBFs, recent evidence revealed that noncoding RNA, such as microRNA and long noncoding RNA, participates in regulating mRNA stability and that aberrant noncoding RNA expression accounts for many pathologic renal conditions. The goal of this review is to provide an overview of our current understanding of the post-transcriptional regulation of mRNA stability in renal pathophysiology and to offer perspectives for this class of diseases. We use examples of diverse renal diseases to illustrate different mRNA stability pathways in specific cellular compartments and discuss the roles and impacts of both the cis- and trans-activating factors on the regulation of mRNA stability in these diseases.-Feigerlová, E., Battaglia-Hsu, S.-F. Role of post-transcriptional regulation of mRNA stability in renal pathophysiology: focus on chronic kidney disease.

Foetal programming by methyl donor deficiency produces steato-hepatitis in rats exposed to high fat diet.

Non-alcoholic steatohepatitis (NASH) is a manifestation of metabolic syndrome, which emerges as a major public health problem. Deficiency in methyl donors (folate and vitamin B12) during gestation and lactation is frequent in humans and produces foetal programming effects of metabolic syndrome, with small birth weight and liver steatosis at day 21 (d21), in rat pups. We investigated the effects of fetal programming on liver of rats born from deficient mothers (iMDD) and subsequently subjected to normal diet after d21 and high fat diet (HF) after d50. We observed increased abdominal fat, ASAT/ALAT ratio and angiotensin blood level, but no histological liver abnormality in d50 iMDD rats. In contrast, d185 iMDD/HF animals had hallmarks of steato-hepatitis, with increased markers of inflammation and fibrosis (caspase1, cleaved IL-1ß, α1(I) and α2(I) collagens and α-SMA), insulin resistance (HOMA-IR and Glut 2) and expression of genes involved in stellate cell stimulation and remodelling and key genes triggering NASH pathomechanisms (transforming growth factor beta super family, angiotensin and angiotensin receptor type 1). Our data showed a foetal programming effect of MDD on liver inflammation and fibrosis, which suggests investigating whether MDD during pregnancy is a risk factor of NASH in populations subsequently exposed to HF diet.
