Use of insulin degludec in pregnancy: two case reports and a literature review

Abstract As of now, insulin Degludec has no indication for use in pregnancy, because of the lack of studies that prove its safety for foetus. However it isn't infrequent that some women conceive while treating with insulin Degludec. So, before deciding to change the type of insulin therapy during pregnancy, an evaluation of the risk associated to a possible temporary worsening of glycaemic control, due to that insulin replacement, is needed. Referring to case series reported in the scientific literature could provide a support when a clinical decision need to be taken. We report two cases of women affected by type 1 diabetes who had unplanned pregnancies during treatment with insulin Degludec. In order to avoid the risk of a possible worsening of glycaemic control due to insulin switch, we decided to continue the treatment with Degludec during their pregnancies, after obtaining the patients' written informed consent. Daily insulin requirement gradually increased for both women pregnancy progressed, and glycated haemoglobin (HbA1c) values improved from the first observation to delivery: 55 mmol/mol (7.2%) at 9 weeks to 47 mmol/mol (6.5%) at 36 weeks, in Patient 1 (P1); 44 mmol/mol (6.2%) at 8 weeks to 33 mmol/mol (5.2%) at 36 weeks, in Patient 2 (P2). P1 delivered at week 37 with a caesarean section due to failed induction. The newborn, a girl of 3398 g at birth, developed neonatal hypoglycaemia and respiratory distress (Apgar 6-6). Six days after birth she underwent colectomy because of necrotizing enterocolitis and was finally diagnosed with atypical cystic fibrosis. P2 gave birth to a healthy girl (weight 2745g at birth, Apgar 7-9) at 37 weeks, undergoing a caesarean section for maternal cervical dystocia, without neonatal complications. Our experience provides additional evidence on the safety of insulin Degludec in pregnancy without any maternal or neonatal outcome suggesting its toxicity

Learning impact of education during pulmonary rehabilitation program. An observational short-term cohort study

Background: Among the several components integrating a pulmonary rehabilitation (PR) course, education may contribute to the individual\u2019s recognition of symptoms and worsening of the disease. However, the specific gain of education is far to be clearly documented to the health care providers. Aim of our preliminary study was to assess the learning impact of educational sessions (ES) in Chronic Obstructive Pulmonary Disease (COPD) patients referred to standard PR.Methods: Six ES on 3 areas (Symptoms-Therapies, Aids, Mood) were applied during PR at our clinic. The learning effect was prospectively evaluated by a specific questionnaire (ESQ) in 285 COPD patients (age 69\ub18 years, FEV1 53\ub114 % pred), then grouped into those who have completed ES (Completers group, n=226) or who did not (mean 2\ub11 ES) (Control group, n=59). Total and partial ESQ scores, and PR outcomes (6-minute walking test-6MWD, effort-dyspnoea at Medical Research Council scale-MRC, and health-related quality of life scale-SGRQ) were assessed in a pre (T0) to post (Tend) design.Results: Similar improvement in PR outcomes was recorded in both groups at Tend, whereas ESQ total and partial scores significantly increased in Completers only (p<0.001). ESQ-Aids score improved to a greater extent in Completers than in Control (+0.60\ub11.03 vs +0.27\ub11.27 point respectively, p=0.036). A higher proportion of Completers improved above the median change of both ESQ total and aids scores (p<0.05).Conclusion: Attending educational sessions produces a specific short-term learning effect during rehabilitation of COPD patients

SAT0280 IMPACT OF PLACENTAL FACTORS ON PREGNANCY AND FETAL OUTCOME IN SYSTEMIC SCLEROSIS

Background:Systemic Sclerosis (SSc) is one of the rheumatic diseases burdened with obstetrical complications. An Italian multicenter study showed that women with SSc have a higher-than-normal risk of intrauterine growth restriction, preterm delivery, very-low birth weight babies and pregnancy should be discouraged in patients with severe organ damage. However, with a multidisciplinary management, patients with SSc can have successful outcomes1. Little is known about the pathogenesis of obstetrical complications, as studies on placenta are case reports or description of a few cases2,3.Objectives:The aim of this study was to analyze the placental alterations with a focus on the role of inflammation in the pathogenesis of obstetrical complications in SSc, including the study of the atypical chemokine receptor 2 (ACKR2), involved in immune modulation and known to be highly expressed in circulating leucocytes in SSc patients4-6.Methods:Eight SSc pregnant patients were compared with 16 patients with other rheumatic diseases (ORD) and 16 healthy controls (HC), matched for gestational age. Clinical data were collected. Placentas biopsies were obtained for histopathological analysis and immunohistochemistry for CD3, CD20, CD11c, CD68 and ACKR2. Frozen placenta samples from 4 SSc, 8 ORD and 8 HC were analyzed by qPCR for ACKR2 gene expression and proteins were extracted for multiplex assay for cytokines, chemokines and growth factors involved in angiogenesis and inflammation. Statistical analysis was performed with parametric or non-parametric tests depending on samples distribution.Results:The number of placental CD3 (p<0.05), CD68 (p<0.001) and CD11c+ (p<0.001) cells was significantly higher considering the group of patients affected by rheumatic diseases (SSc+ORD) compared to HC. The SSc group alone did not show significance due to the lower sample size. No differences were observed between groups in terms of vascular alterations or fibrosis. The percentage of stained area for ACKR2 and the ACKR2 transcripts levels were comparable between groups. Hepatocyte growth factor (HGF), involved in angiogenesis, was significantly increased in the group of rheumatic diseases patients (SSc+ORD) compared to HC (p<0.05), while the chemokine CCL5 was significantly higher in SSc patients compared to patients affected by ORD (p<0.05) and to HC (p<0.01). CCL5 levels directly correlated with the number of all inflammatory cells considered and higher levels were associated to histological villitis (p<0.01).Conclusion:The higher number of placental inflammatory cells and the alterations in the levels of HGF and especially CCL5 could play a role in the pathogenesis of the obstetrical complications in SSc. ACKR2 does not seem involved in the obstetrical complications of SSc.References:[1]Taraborelli M, et al. Arthritis Rheum. 2012[2]Ibba-Manneschi L, et al. Ann Rheum Dis. 2010[3]Doss BJ, et al.

Early, incomplete, or preclinical autoimmune systemic rheumatic diseases and pregnancy outcome

OBJECTIVE: To evaluate the impact of preclinical systemic autoimmune rheumatic disorders on pregnancy outcome. METHODS: In this longitudinal cohort study, patients were enrolled during the first trimester of pregnancy if they reported having had connective tissue disorder symptoms, were found to be positive for circulating autoantibodies, and on clinical evaluation were judged to have a preclinical or incomplete rheumatic disorder. The incidence of fetal growth restriction (FGR), preeclampsia, and adverse pregnancy outcomes in patients with preclinical rheumatic disorders was compared with that in selected controls, after adjustment for confounders by penalized logistic regression. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated. RESULTS: Of 5,232 women screened, 150 (2.9%) were initially diagnosed as having a suspected rheumatic disorder. After a mean\u2009\ub1\u2009SD postpartum follow-up of 16.7\u2009\ub1\u20095.5 months, 64 of these women (42.7%) had no clinically apparent rheumatic disease and 86 (57.3%) had persistent symptoms and positive autoantibody results, including 10 (6.7%) who developed a definitive rheumatic disease. The incidences of preeclampsia/FGR and of small for gestational age (SGA) infants were 5.1% (23 of 450) and 9.3% (42 of 450), respectively, among controls, 12.5% (8 of 640) (OR 2.7 [95% CI 1.1-6.4]) and 18.8% (12 of 64) (OR 2.2 [95% CI 1.1-4.5]), respectively, among women with no clinically apparent disease, and 16.3% (14 of 86) (OR 3.8 [95% CI 1.9-7.7]) and 18.6% (16 of 86) (OR 2.3 [95% CI 1.2-4.3]), respectively, among those with persisting symptoms at follow-up. Mean\u2009\ub1\u2009SD umbilical artery Doppler pulsatility indices were higher among women with no clinically apparent disease (0.95\u2009\ub1\u20090.2) and those with persisting symptoms (0.96\u2009\ub1\u20090.21) than in controls (0.89\u2009\ub1\u20090.12) (P\u2009=\u20090.01 and P\u2009&lt;\u20090.001, respectively). CONCLUSION: In our study population, preclinical rheumatic disorders were associated with an increased risk of FGR/preeclampsia and SGA. The impact of these findings and their utility in screening for FGR/preeclampsia need to be confirmed in population studies

Effect of vessel wettability on the foamability of "ideal" surfactants and "real-world" beer heads

The ability to tailor the foaming properties of a solution by controlling its chemical composition is highly desirable and has been the subject of extensive research driven by a range of applications. However, the control of foams by varying the wettability of the foaming vessel has been less widely reported. This work investigates the effect of the wettability of the side walls of vessels used for the in situ generation of foam by shaking aqueous solutions of three different types of model surfactant systems (non-ionic, anionic and cationic surfactants) along with four different beers (Guinness Original, Banks’s Bitter, Bass No 1 and Harvest Pale). We found that hydrophilic vials increased the foamability only for the three model systems but increased foam stability for all foams except the model cationic system. We then compared stability of beer foams produced by shaking and pouring and demonstrated weak qualitative agreement between both foam methods. We also showed how wettability of the glass controls bubble nucleation for beers and champagne and used this effect to control exactly where bubbles form using simple wettability patterns

Results. Similar improvement in PR outcomes was recorded in both groups at Tend, whereas ESQ total and partial scores significantly increased in ‘Completers’ only (p<0.001). ESQ-Aids score improved to a greater extent in Completers than in Control (+0.60±1.03 vs +0.27±1.27 point respectively, p=0.036). A higher proportion of Completers improved above the median change of both ESQ total and aids scores (p<0.05). Conclusion.
