- BACKGROUND: Laboratory tests to assist in the diagnosis and monitoring of neuroinflammatory diseases are scarce. The soluble form of the CD27 molecule (sCD27) is shed in high concentrations by activated T cells and can be detected in the cerebrospinal fluid. The aim of this study was to investigate whether CSF quantitation of sCD27 could discriminate between inflammatory and non-inflammatory neurological diseases.METHODS: The concentration of sCD27 was measured using a commercially available ELISA in 803 well-defined subjects from a study cohort comprised of 338 patients with neuroinflammatory disease, 338 with non-inflammatory neurological disease and 127 controls without neurological disease.RESULTS: The median value of cerebrospinal fluid sCD27 was 64 pg/mL (IQR 0-200) in controls, 58 pg/mL (IQR 0-130) in patients with non-inflammatory disease and 740 pg/mL (IQR 230-1800) in patients with inflammatory disease. The likelihood ratio of having an inflammatory disease was 10 (sensitivity 74% and specificity 93%) if the sCD27 concentration was >250 pg/mL. In patients with a known inflammatory condition, the likelihood ratio of having an infection was 10 (sensitivity 40% and specificity 96%) if the sCD27 concentration was >2500 pg/mL.CONCLUSIONS: The likelihood of having an inflammatory neurological condition is increased with elevated concentrations of sCD27 in cerebrospinal fluid. Rapid tests of sCD27 should be developed to assist clinicians in diagnosis of neuroinflammatory disease.

- OBJECTIVE: Previous studies show that growth hormone (GH) treatment increases cardiac dimensions in short children with GH deficiency (GHD) and has diverse cardiac effects in children with idiopathic short stature (ISS). This study was performed to assess the effect of GH on the cardiovascular system in short children with a broad range of GH secretion and GH sensitivity/responsiveness. DESIGN AND PATIENTS: In this prospective, multicentre study, short prepubertal children diagnosed with isolated GHD (89) or ISS (38) were followed during two years of GH treatment. They were randomized to receive either a standard (43 μg/kg/d) or individualized GH dose (range 17-100 μg/kg/d) based on GH responsiveness estimated by a prediction model and distance to target height. Echocardiography, blood pressure and electrocardiography were performed at baseline, 3, 12 and 24 months. RESULTS: Left ventricular mass (LVM) indexed to body surface area increased significantly during two years of GH treatment in both GHD and ISS irrespective of randomized dose. This change was already apparent at three months, when standard deviation scores (SDS) of wall thickness and diameter were increased. At 24 months, left ventricular diameter SDS remained increased whereas myocardial thickness SDS returned to baseline values. There was no impairment of systolic or diastolic function. There was no correlation with treatment dose and LVM SDS at 24 months. CONCLUSIONS: Irrespective of GH status, there was a rapid increase in LVM during GH treatment in short children. At 3 months, wall thickness and diameter were increased whereas only diameter remained increased at 24 months. © 2012 Blackwell Publishing Ltd.

- AimFew studies have been published on children with hereditary angioedema (HAE), an autosomal dominant disease caused by mutations on chromosome 11. This study explored various aspects of the disease in the Swedish paediatric population. MethodsA retrospective questionnaire was sent to all 36 Swedish children known to have HAE, and a physician carried out follow-up telephone interviews. ResultsMost of the questionnaires were completed by the parents of 31 (86%) children with HAE, with or without their input, at a median age of nine years (range 1-17), and the physician also interviewed 29. HAE symptoms were experienced by 23 children, including abdominal attacks (96%), skin swelling (78%) and swelling in the mouth and/or upper airways (52%). Psychological stress was the most common trigger for abdominal attacks and trauma and sports triggered skin swelling. The majority (n = 19) had access to complement-1 esterase inhibitor concentrate at home. Current health and quality of life were generally rated as good, independent of whether the child had experienced HAE symptoms or not. ConclusionMost children with HAE had experienced abdominal attacks and skin swelling, but their overall health and quality of life were generally perceived to be good.

- In the past 20 years, a significant improvement has been shown in the treatment for infertility in both women and men through the development of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Only donated sperm could be previously used for treatment; now oocytes can also be donated. Furthermore, the combination of IVF and ICSI with advanced genetic methods has made preimplantation genetic diagnosis possible for many genetic conditions. These methods enable genetic testing of the early human embryo by using only a single cell, one blastomere biopsied from the embryo, as the sample from which the diagnosis of many chromosome rearrangements and other inherited diseases can be made. It has also been established that a considerable proportion of infertility is caused by genetic defects, which have several implications for infertility treatment. The purpose of this review is to give a concise introduction on how genetics is involved in assisted reproduction technology to specialists who may not be working in this particular field of gynecology, but who would need some knowledge of this for proper care of their patients.

Safety issues in assisted reproduction technology: should ICSI patients have genetic testing before treatment? A practical proposition to help patient information

- ICSI is a highly efficient treatment of male factor infertility and therefore increasingly used to treat infertile men successfully. However, when used to treat patients with a genetic cause for their infertility, there may be an increased risk for the offspring. Chromosome aberrations, Y chromosome microdeletions and CFTR (cystic fibrosis transmembrane conductance regulator) mutations alone may explain up to 25% of azoospermia and severe oligozoospermia. These genetic defects could be identified before treatment, in which case informed decisions could be made by the couple to be treated concerning the treatment, prenatal testing or preimplantation genetic diagnosis. Therefore, we propose that men with very low sperm counts (<5 x 10(6)/ml) considering ICSI should always be informed of the possibility of genetic testing. The information should include a precise statement of the implications of the results for the patient, his family and his offspring, and reassurance that a decision to test or not to test, or the subsequent test results will not be used as a reason for withholding treatment. Testing should always remain voluntary, and the couples themselves should decide whether or not they choose to be tested. If an abnormality is identified, patients should be referred to specialist genetic counselling.

- ObjectiveFontan surgery is performed in children with univentricular heart defects. Previous data regarding permanent pacemaker implantation frequency and indications in Fontan patients are limited and conflicting. We examined the prevalence of and risk factors for pacemaker treatment in a consecutive national cohort of patients after Fontan surgery in Sweden. MethodsWe retrospectively reviewed all Swedish patients who underwent Fontan surgery from 1982 to 2017 (n=599). ResultsAfter a mean follow-up of 12.2years, 13% (78/599) of the patients with Fontan circulation had received pacemakers. Patients operated with the extracardiac conduit (EC) type of total cavopulmonary connection had a significantly lower prevalence of pacemaker implantation (6%) than patients with lateral tunnel (LT; 17%). Mortality did not differ between patients with (8%) and without pacemaker (5%). The most common pacemaker indication was sinus node dysfunction (SND) (64%). Pacemaker implantation due to SND was less common among patients with EC. Pacemaker implantation was significantly more common in patients with mitral atresia (MA; 44%), double outlet right ventricle (DORV; 24%) and double inlet left ventricle (DILV; 20%). In contrast, patients with pulmonary atresia with intact ventricular septum and hypoplastic left heart syndrome were significantly less likely to receive a pacemaker (3% and 6%, respectively). ConclusionsThirteen percent of Fontan patients received a permanent pacemaker, most frequently due to SND. EC was associated with a significantly lower prevalence of pacemaker than LT. Permanent pacemaker was more common in patients with MA, DORV, and DILV.

- Sinus node dysfunction (SND) causes significant morbidity in patients after Fontan surgery. Heart rate variability (HRV) reflects the autonomic regulation of the heart, and changes in HRV have been associated with SND in adults. We aimed to study whether changes in HRV could be detected in 24-h electrocardiographic (ECG) recordings in Fontan patients with SND. We compared HRV results from two patient groups; patients with Fontan circulation who later required a pacemaker due to severe SND (n = 12) and patients with Fontan circulation and SND, without indication for pacemaker treatment (n = 11), with two control groups; patients with Fontan circulation without SND (n = 90) and healthy controls (n = 66). The Poincare plot index SD2 (representing changes in heart rate over 24-h) and the very low-frequency (VLF) HRV component were significantly higher in both SND groups, both compared with healthy controls and patients with Fontan circulation without SND. In SND patients with pacemakers, SD2 and VLF were slightly reduced compared to SND patients without pacemaker (p = 0.06). In conclusion, in Fontan patients with SND the HRV is significantly higher compared to healthy controls and Fontan patients without SND. However, in patients with severe SND requiring pacemaker, SD2 and VLF tended to be lower than in patients with SND without pacemaker, which could indicate a reduced diurnal HRV in addition to the severe bradycardia. This is a small study, but our results indicate that HRV analysis might be a useful method in the follow-up of Fontan patients regarding development of SND.
