RESUMEN

OBJECTIVE: To assess the incidence of serious complications and reoperations for recurrence after surgery for pelvic organ prolapse (POP) and compare the three most common types of repair. DESIGN: Prospective cohort study using a registry. SETTING: Nineteen French surgical centres. POPULATION: A total of 2309 women participated between 2017 and 2019. METHODS: A multivariate analysis including an inverse probability of treatment weighting approach was used to obtain three comparable groups. MAIN OUTCOME MEASURES: Serious complications and subsequent reoperations for POP recurrence. RESULTS: The median follow-up time was 17.6 months. Surgeries were native tissue vaginal repairs (n = 504), transvaginal mesh placements (n = 692) and laparoscopic sacropexies with mesh (n = 1113). Serious complications occurred among 52 women (2.3%), and reoperation for POP recurrence was required for 32 women (1.4%). At 1 year the cumulative weighted incidence of serious complications was 1.8% for native tissue vaginal repair, 3.9% for transvaginal mesh and 2.2% for sacropexy, and the rates for reoperation for recurrence of POP were 1.5, 0.7 and 1.1%, respectively. Compared with native tissue vaginal repair, the risk of serious complications was higher in the transvaginal mesh group (weighted hazard ratio, wHR 3.84, 95% CI 2.43-6.08) and the sacropexy group (wHR 2.48, 95% CI 1.45-4.23), whereas the risk of reoperation for prolapse recurrence was lower in both the transvaginal mesh (wHR 0.22, 95% CI 0.13-0.39) and sacropexy (wHR 0.29, 95% CI 0.18-0.47) groups. CONCLUSIONS: Our results suggest that native tissue vaginal repairs have the lowest risk of serious complications but the highest risk of reoperation for recurrence. These results are useful for informing women and for shared decision making. TWEETABLE ABSTRACT: Laparoscopic sacropexy had fewer serious complications than transvaginal mesh and fewer reoperations for recurrence than vaginal repair.

RESUMEN

OBJECTIVE: To assess the short-term incidence of serious complications of surgery for urinary incontinence or pelvic organ prolapse. DESIGN: Prospective longitudinal cohort study using a surgical registry. SETTING: Thirteen public hospitals in France. POPULATION: A cohort of 1873 women undergoing surgery between February 2017 and August 2018. METHODS: Preliminary analysis of serious complications after a mean follow-up of 7 months (0-18 months), according to type of surgery. Surgeons reported procedures and complications, which were verified by the hospitals' information systems. MAIN OUTCOME MEASURES: Serious complication requiring discontinuation of the procedure or subsequent surgical intervention, life-threatening complication requiring resuscitation, or death. RESULTS: Fifty-two women (2.8%, 95% CI 2.1-3.6%) experienced a serious complication either during surgery, requiring the discontinuation of the procedure, or during the first months of follow-up, necessitating a subsequent reoperation. One woman also required resuscitation; no women died. Of 811 midurethral slings (MUSs), 11 were removed in part or totally (1.4%, 0.7-2.3%), as were two of 391 transvaginal meshes (0.5%, 0.1-1.6%), and four of 611 laparoscopically placed mesh implants (0.7%, 0.2-1.5%). The incidence of serious complications 6 months after the surgical procedure was estimated to be around 3.5% (2.0-5.0%) after MUS alone, 7.0% (2.8-11.3%) after MUS with prolapse surgery, 1.7% (0.0-3.8%) after vaginal native tissue repair, 2.8% (0.9-4.6%) after transvaginal mesh, and 1.0% (0.1-1.9%) after laparoscopy with mesh. CONCLUSIONS: Early serious complications are relatively rare. Monitoring must be continued and expanded to assess the long-term risk associated with mesh use and to identify its risk factors. TWEETABLE ABSTRACT: Short-term serious complications are rare after surgery for urinary incontinence or pelvic organ prolapse, even with mesh.

RESUMEN

AIMS: Several reports have suggested a relationship between male sex and albuminuria in Type 2 diabetes, but impact on renal function decline has not been established. Our aim was to describe the influence of sex on renal function decline in Type 2 diabetes. METHODS: SURDIAGENE, an inception cohort, consisted in 1470 people with Type 2 diabetes. Patients without renal replacement therapy and with ≥ 3 serum creatinine determinations during follow-up prior to end-stage renal disease were included in the study. Estimated glomerular filtration rate was calculated using the Chronic Kidney Disease Epidemiology Collaboration equation. Primary outcome was steep estimated glomerular filtration rate (eGFR) decline, defined as a yearly slope value lower than -3.5 ml min(-1) 1.73 m(-2). Secondary outcomes were estimated glomerular filtration rate trajectories according to sex and occurrence of end-stage renal disease. RESULTS: A total of 22 914 serum creatinine determinations were considered in 1146 participants (60% men), aged 65 ± 11 years, with a median follow-up duration of 5.7 years (range 0.1-10.2). Median yearly estimated glomerular filtration rate slope was -1.31 ml min(-1) 1.73 m(-2) in women and -1.77 ml min(-1) 1.73 m(-2) in men (P < 0.001). Men were more likely than women to develop end-stage renal disease (22 men vs. 7 women; P(log-rank) = 0.03). Male sex was an independent risk factor of steep estimated glomerular filtration rate decline [adjusted odds ratio = 1.33 (1.02-1.76), P = 0.04] after adjustment for age, time from diagnosis of Type 2 diabetes, glycated haemoglobin, systolic blood pressure and urinary albumin:creatinine ratio. A multivariable linear mixed-effects model showed a significant difference of estimated glomerular filtration rate trajectories between men and women (P < 0.001). CONCLUSION: Male sex is an important independent factor associated with renal function decline in Type 2 diabetes.

RESUMEN

Peripheral inflammation mechanisms involved in Alzheimer's disease (AD) have yet to be accurately characterized and the identification of blood biomarker profiles could help predict cognitive decline and optimize patient care. Blood biomarkers described to date have failed to provide a consensus signature, which is mainly due to the heterogeneity of the methods used or the cohort. The present work aims to describe the potential informativity of peripheral inflammation in AD, focusing in particular on the potential association between the level of plasma neurofilament light (NFL), peripheral inflammation (by quantifying IL-1ß, IL-6, TNFα, CCL5, TNF-R1, sIL-6R, TIMP-1, IL-8 in blood) and cognitive decline (assessed by the MMSE and ADAScog scales) through a 2-year follow-up of 40 AD patients from the Cytocogma cohort (CHU Poitiers, Pr M. Paccalin). Our results show for the first time a strong correlation between plasma NFL and TNF-R1 at each time of follow-up (baseline, 12 and 24 months), thus opening an interesting perspective for the prognosis of AD patients.

RESUMEN

UNLABELLED: Impairment of the Self has been described in frontal-temporal dementia but little research has been carried out in patients with Alzheimer's disease (AD). OBJECTIVE: The aim of this study was to explore changes in the self in patients with AD. METHOD: Forty-seven patients with mild to moderate AD were examined using a semi-structured scale designed to assess the self-concept along three dimensions, namely, the Material Self, the Social Self and the Spiritual Self. RESULTS: The majority of patients (43 out of 47) presented impairment of at least one dimension of the Self. When only one dimension was affected, it was always the Social Self. The severity of impairment of the Self was correlated to the impairment of the semantic autobiographical memory and apathy. CONCLUSION: The Self is impaired in AD and the Social Self dimension appears to be more vulnerable in AD than other dimensions.

RESUMEN

BACKGROUND: Telomeres are complex structures formed by the end of the DNA molecule at the tip of chromosomal arms. The telomeric sequence, which results from the repetition of the hexanucleotide TTAGGG, is partly single strand and is associated with more than ten proteins, including the enzyme telomerase. Because of the characteristics of the DNA replication process, only telomerase is able to elongate the telomeric sequence. Since the telomerase gene is repressed in virtually all the somatic cells, telomeres progressively shorten at each S phase of the cell cycle, and this shortening is accelerated by oxidative stress. A critically shortened telomere activates the genetic program of cell senescence and/or apoptosis. The telomere length measured in peripheral blood leucocytes is considered a reliable marker of biological age, mortality risk and exposure to various pathological conditions, including cardiovascular disease, dementia and metabolic syndrome. Telomere erosion has been observed in psychiatric disorders including schizophrenia and mood disorders, suggesting an accelerated aging of 10 to 20 years. Whether this peripheral dynamic is reflected by a similar pattern in the brain remains unknown. To address this issue, we have measured the telomere length in the occipital DNA cortex of 24 patients with major depressive disorder and 12 controls (donated by the Stanley Research Institute). METHODOLOGY: The mean telomere length has been evaluated by a real time quantitative PCR technique, which amplified the telomere sequence and a reference single copy sequence. Results have been expressed by the ratios of Ct obtained for the two amplification curves. RESULTS: The mean Ct values were strictly identical (0.79 ± 0.001) and the 36 PCR curves were coincident. DISCUSSION: This study demonstrates for the first time that there is no shortening of telomeres in the cortex of patients with depressive disorder. Previous results have shown that in normal tissues telomeres length is inversely correlated to age, even in non proliferating tissues, but that the change is minimal in the brain. Thus, although consistent evidence for the role of a systemic and brain inflammation associated oxidative stress in depression has been provided, it must be concluded that the cerebral state of telomeres is not affected by the mechanism operating in the leucocytes. This observation raises the issue of the relation between the psychiatric pathological process and the peripheral telomere marker. It suggests the existence of specific telomere stabilizing factors in the cortex cells.

RESUMEN

Polymicrogyria (PMG) is a relatively common malformation of the cortex for which the pathogenesis remains poorly understood. Both acquired and genetic causes are known, and to date more than 70 cases of PMG have been associated with chromosomal abnormalities. Here we report on a 12-year-old girl presenting with asymmetrical PMG predominantly affecting the right occipital lobe. She was the only child of consanguineous parents. At 7 years of age she was referred for mental retardation with speech delay and seizures. Cytogenetic studies of the patient revealed an inverted 9p duplication/deletion and bacterial artificial chromosomes (BACs)-array also showed a 22q11.2 microduplication confirmed by quantitative PCR. This case is of interest in the search for candidate genes and emphasizes the importance of the 22q11 region in PMG. It also highlights the efficiency of BACs-array in detecting complex rearrangements.

RESUMEN

Despite its widespread use, there are many concerns about the efficacy of aspirin in the secondary prevention of cardiovascular events after stroke, leading to the concept of aspirin non-response (ANR). Although the mechanisms of ANR remain uncertain, it is expected to be due to a combination of clinical, biological and genetic characteristics affecting platelet function. In this study, we investigated whether clinical and/or biological factors such as hypertension and platelet response to ADP could contribute to the ANR. As a secondary objective, we determine whether ANR and collagen/ADP closure time (CADP-CT) could be related to platelet glycoprotein single nucleotide polymorphisms (SNPs). One hundred patients on aspirin (160 mg/day) were enrolled. ANR was measured with a platelet function analyzer (PFA-100); genotyping of four SNPs (GP IIIa, GP Ia, P2Y12 and GP VI) was performed using a tetra-primer amplification refractory mutation system. Using a collagen/epinephrine-coated cartridge on the PFA-100, the prevalence of ANR was 15% (n = 15). In the ANR group, (i) CADP-CT was significantly shorter and (ii) hypertension was an independent clinical predictive factor of ANR (OR = 4.25; 95%CI: 1.06-17.11). No clear relation was found between CADT-CT and platelet gene polymorphism as well as ANR status and SNPs. In conclusion our study confirms the independent relationship between hypertension, platelet hypersensitivity to ADP and aspirin (160 mg/day) non-response. The differential sensitivity to aspirin may have potential clinical implications, where adaptation of antiplatelet therapy is necessary according to a patient's clinical and genetic characteristics.

RESUMEN

OBJECTIVE: To evaluate secondary effects on cognitive functions as memory and attention impairments in men treated by androgen suppression for cancer of prostate. MATERIAL AND METHODS: A prospective study on men treated with luteinizing hormone-realising hormone analogues (LH-RH analogues) for cancer of prostate was designed. Eighteen men were evaluated with cognitive tests as Mini Mental State (MMS), memory evaluation (Grober-Buschke, Rey Test), attention and executive test (Trail Making Test and Montgomery Asberg Depression Rating Scale [MADRS]) before beginning androgen suppression. Base line pretreatment assessments of every patient were compared with similar tests after six and 12 months of hormone therapy. RESULTS: On 18 patients, 14 were eligible with pretreatment-median PSA of 22ng/ml (13-659), testosterone of 477ng/dl (398-583), which decreased to 1 and 37ng/dl, respectively. Visual-memory test (Rey test) was significantly improved at M6 (p: 0,001) and M12 (p: 0,02) as was the inversed number-memory test (WAIS) after M6 of androgen suppression and (p: 0,03). CONCLUSION: After 12 months of androgen suppression, global cognitive performances were preserved. Our results failed to observe impairment of cognitive function. This deserves more important prospective study.

RESUMEN

AIM: Type A personality has been associated with increased survival in people with type 1 diabetes (T1D). Systemic low-grade inflammation may play a critical role, as suggested in recent reports, although the links between the inflammatory circulating transcriptome and Type A remain unknown. This prompted our exploration of the potential associations between Type A personality and c-Fos gene expression, a candidate gene closely linked to inflammatory processes, in T1D. METHODS: Type A personality was assessed by Bortner questionnaire in patients with T1D, and two subscales - 'speed' and 'competitiveness' - were used to measure these specific dimensions of Type A. Expression of the c-Fos gene was assessed by a quantitative real-time polymerase chain reaction technique. RESULTS: This pilot study included 20 men with T1D. Multivariable analyses showed an independent inverse association between Type A competitiveness score and c-Fos expression, while a regression model adjusted for age, body mass index and HbA1c levels revealed a significant inverse relationship between c-Fos transcripts and Type A competitiveness (P = 0.003). CONCLUSION: This strong association between Type A competitiveness and reduced c-Fos expression is in line with recent data suggesting a psychobiological influence of the Type A profile in T1D via inflammatory pathways.

RESUMEN

OBJECTIVE: Hemofilter thrombosis occurs frequently during continuous veno-venous hemofiltration in intensive care units. Among coagulation disorders, antithrombin deficiency has been shown to be linked to hemofilter thrombosis. We investigated whether there was an association between antithrombin level activity and hemofilter thrombosis occurrence during early continuous hemofiltration following cardiopulmonary bypass. DESIGN: Prospective observational study. SETTING: Intensive care unit in University Teaching Hospital. PATIENTS AND PARTICIPANTS: Forty-eight consecutive patients. MEASUREMENTS AND RESULTS: Antithrombin level activity was measured just before the start of hemofiltration, and repeated at 24 h intervals for a total of 3 days. Hemofilter thrombosis episodes were recorded at each 24-h interval following antithrombin level activity measurement. Subjects were classified as HT when one or more episodes of hemofilter thrombosis appeared in this period and NHT if none. Morbidity parameters and mortality were recorded. Mean initial antithrombin level activity was low and not different in HT and NHT groups at day 0 (60.6 +/- 20.9% vs. 63.4 +/- 19.9%, P = 0.68). Antithrombin level activity was lower at day 1 (47.2 +/- 12.0% vs. 58.2 +/- 15.2%, P = 0.03) and day 2 (41.2 +/- 15.3% vs. 53.5 +/- 14.1%, P = 0.04) in HT group. However, antithrombin level activity was not shown to be predictive of HT in multivariate analysis. Morbidity and mortality did not differ significantly between the two groups. CONCLUSION: Only a weak association was found between antithrombin level activity and HT during early veno-venous hemofiltration post-cardiopulmonary bypass. This result was not confirmed in multivariate analysis. DESCRIPTOR: Renal failure: dialysis and hemofiltration.

RESUMEN

BACKGROUND: Radiofrequency heating of the intervertebral disc has been proposed for the treatment of chronic low back pain using two methods: a flexible needle inserted into the annulus fibrosus achieving a full 360 degrees penetration, or a rigid needle inserted into the nucleus pulposus. The first technique is effective on pain, but the clinical benefit of the second is uncertain. PURPOSE: To evaluate a technique for radiofrequency heating of the lumbar intervertebral disc by a needle placed into the nucleus pulposus. MATERIAL AND METHODS: The method was tested in 17 patients according to the criteria used in previous intradiscal radiofrequency studies. Before and after treatment, disability was assessed by the Oswestry disability score. A pain reduction of at least 50% was considered a success. RESULTS: Fifteen patients were responders at 1 month (88%), nine at 3 months (53%), and 12 at 6 months (70.6%). No complications were observed. CONCLUSION: A new method of providing discal radiofrequency treatment for lower back pain had a substantial clinical benefit in 71% of the observed patients. A prospective study comparing this new method with placebo should be conducted to confirm these initial results.

RESUMEN

OBJECTIVES: To compare the risk of relapse of vertebral osteomyelitis (VO), according to the duration of antibiotic therapy (< or =6 weeks versus >6 weeks). METHODS: We performed a 10-year retrospective study to assess the risk of VO relapse and to verify that this risk was not enhanced in patients who received 6 weeks of antibiotic therapy (Group 1) as compared with those who received a longer treatment (Group 2). VO was diagnosed based on clinical manifestations, magnetic resonance imaging and/or computed tomography findings, and isolation of a pyogenic organism in blood cultures and/or a discovertebral biopsy. Relapse was diagnosed based on isolation of the same organism in blood cultures and/or a discovertebral biopsy. Outcome was evaluated 6 months post-treatment and in December 2004. RESULTS: Group 1 included 36 patients (mean age, 58 +/- 15 years) and Group 2 included 84 patients (mean age, 67 +/- 15 years) (P = 0.003). Clinical data and microorganisms were comparable in the 2 groups. In the first 6 months, 6 (5%) patients died (Group 1, n = 2; Group 2, n = 4), and 5 (4%) in Group 2 relapsed, 2 with recurrent VO and 3 with recurrent bacteremia. In 2004, 91 patients were evaluated (mean follow-up, 40.6 +/- 31 months): 77 (85%) were cured, 13 (14%) died (Group 1, n = 3; Group 2, n = 10), 1 had VO due to a different microorganism (Group 2), and no long-term relapses occurred. CONCLUSION: Our results suggest that antibiotic therapy of VO could be safely shortened to 6 weeks without enhancing the risk of relapse.

RESUMEN

BACKGROUND: Adult growth hormone (GH) deficiency must be diagnosed before prescribing therapeutic recombinant human GH. We studied the clinical relevance of a diagnostic strategy for growth hormone deficiency (GHD) using IGF-1 determination as a first step. METHODS: In 2000 and 2001, we tested 142 adult patients with hypothalamo-pituitary disorders for somatotropic function using Insulin Tolerance Test (ITT), the reference test for the diagnosis of GHD, with concomitant Insulin-like growth factor-1 (IGF-1) determination, a marker of somatotropic function. Patients were classified as GHD (peak GH concentration<3 ng/ml with the ITT) or normal. SETTING: Monocenter prospective study in a tertiary referral center. RESULTS: GHD was diagnosed in 61 subjects. Using a ROC curve, a threshold IGF-1 concentration of 175 ng/ml yielded a negative predictive value of 89+/-5%. A diagnostic strategy with IGF-1 determination as the first step followed by ITT for patients with an IGF-1 concentration below 175 ng/ml missed five of the 61 GHD patients, avoided 46/142 ITT and reduced the cost of diagnosis by 15%. CONCLUSION: We propose the use of a strategy consisting of IGF-1 determination followed, if below 175 ng/ml by confirmatory ITT to diagnose GHD in adults.

RESUMEN

OBJECTIVE: Selenium deficiency adversely affects the clinical outcome of measles in the tropics. In developed countries, serum selenium level has never been investigated during acute measles. The aim of this study was to determine serum selenium concentrations in French patients with acute measles and to seek correlations with clinical and virological findings. PATIENTS AND METHODS: We studied serum selenium concentrations in 94 French patients with acute measles and in 99 healthy controls matched for age and sex. RESULTS: The mean of selenium concentration was significantly lower in the patients than in the controls (46.4±14.1µg/L versus 86.5±13.9µg/L, P<0.0001). In the patients, selenium concentrations were not associated with age, sex, vaccination status, clinical signs or specific antibody responses. Selenium levels did not differ significantly between patients with uncomplicated measles (45.8±14.2µg/L) and patients with complications (52.7±13.2µg/L) (P=0.15). CONCLUSION: Acute measles is associated with significant reduction of selenium level that did not seem to negatively affect the course of the disease suggesting compensating mechanisms in patients from developed countries against the disease.

RESUMEN

BACKGROUND: Allergic bronchopulmonary aspergillosis (ABPA) affects 3-13% of patients with asthma. Its natural history includes possibly life-threatening exacerbations and evolution towards fixed obstructive ventilatory disorders or even irreversible lung fibrosis lesions. ABPA prognosis is directly associated with exacerbation control and the main objective of the treatment is to decrease their frequency and duration. Recommendations regarding dosage and duration of treatment are not very precise. The currently used combination of itraconazole and corticosteroid therapy has many limitations. The interests of a therapeutic strategy using nebulized liposomal amphotericin B (LAmB) are to heighten antifungal lung tissue concentration, to circumvent drug interactions and decrease the potential toxicity of systemic antifungal treatments. Finally, this association leads to improved eradication of Aspergillus, thereby limiting the risk of side effects and the emergence of treatment-resistant Aspergillus strains. METHODS: This is a phase II, multicentre, randomized, single blind, controlled therapeutic study, with the objective of comparing the potential benefit on exacerbation control of a maintenance therapy by LAmB nebulization. The main objective of the study is to compare the incidence of severe clinical exacerbations in ABPA treatment, between a maintenance treatment strategy with nebulized LAmB and a conventional strategy without antifungal maintenance therapy. EXPECTED RESULTS: The results will guide practitioners in the management of ABPA treatments and help to define the place of aerosols of LAmB on "evidence base medicine" criteria.

RESUMEN

BACKGROUND: Greater renal function decline (RFD) in type 2 diabetes (T2DM) has been suggested in men compared with women, and imbalances in estrogen/androgen levels have been associated with cardiovascular disease mortality in elderly men, but it remains unclear whether sex hormone disequilibrium is related to diabetic nephropathy (DN) in men with T2DM. OBJECTIVE: This study examined the relationship between sex steroid concentrations and renal outcomes in male T2DM patients. POPULATION AND METHODS: Total testosterone (T), total estradiol (E2), sex hormone-binding globulin (SHBG), and total and calculated free (cf) E2/T ratios were compared in 735 male T2DM patients with (n=513) and without (n=222) DN, using a cross-sectional approach. Also, in a pilot complementary prospective nested case-control cohort, total E2/total T and cfE2/cfT were evaluated according to a hard renal outcome (HRO): end-stage renal disease/doubling of baseline serum creatinine (36 HRO cases, 72 HRO controls) and rate of eGFR decline (68 rapid vs 68 slow RFD). RESULT: With the cross-sectional approach, E2 and cfE2 were higher in DN cases vs DN controls (95.5 vs 86.8pmol/L [P=0.0246] and 2.59 vs 2.36pmol/L [P=0.005], respectively). The difference in E2 persisted on multivariate analysis. In the prospective approach, E2 and T concentrations, and total E2/total T and cfE2/cfT2 ratios did not differ in HRO cases vs controls or in patients with rapid vs slow RFD. CONCLUSION: Although positively related to DN in the cross-sectional analysis, progression of renal disease in male patients with T2DM was not related to either sex hormone levels or aromatase index as reflected by E2/T ratio.

RESUMEN

High rates of uncontrolled hypertensives have been reported in France as well as in other countries, partly owing to an inadequate management of hypertension by clinicians. The objectives of the study were (1) to describe the therapeutic decisions faced by general practitioners (GP) in hypertensives not controlled by fixed-dose combination antihypertensive therapy with a renin-angiotensin system (RAS) inhibitor and a diuretic (D) and (2) to evaluate the frequency with which ambulatory blood pressure monitoring (ABPM) is used in these patients. Each GP had to include five uncontrolled hypertensives on fixed-dose RAS inhibitor and D combination. A total of 2118 GPs included 9551 patients; 8643 patients were receiving at least one of the two drugs at a low dose (group 1) and the remaining 908 patients were receiving high doses of both drugs (group 2). The most common therapeutic choice was that of a new combination, either a fixed-dose in one pill or with separate preparations: 65% (n=5621) in group 1 and 56% (n=505) in group 2. An increase in dose was chosen in 28% of patients in group 1 (n=2467) and continuation of treatment without modification in 27% of patients in group 2 (n=242). A third active principle was only added in 2.5% of patients in group 1 (n=219) and 11% in group 2 (n=103). Ambulatory blood pressure monitoring was employed in 25% of patients (n=2413). An improvement in hypertension management should be expected from the implementation of the 2005 French guidelines.

RESUMEN

OBJECTIVE: To investigate the frequency of main symptoms of Obstructive Sleep Apnea Syndrom (OSAS) and their relationship with Pregnancy Induced-Hypertension (PIH) as well as Intrauterine Growth Retardation (IGR) as suggested by recent studies. METHODOLOGY: Four hundred (and) thirty-eight enquiry forms completed during post-partum period were analysed, after exclusion of multiple pregnancies. Collected data were demographic characteristics, obstetrical events, sleep disorders during last trimester, screening of snoring and vigilance troubles with an Epworth score. RESULTS: Forty-five percentages of the patients reported to have habitual snoring during pregnancy. Among these, 85% were non-snorers before pregnancy. Daytime somnolence concerned 84,5% of the population with an Epworth score significatively increased (P<0,0001). The prevalence of PIH was found to be 4,5%, with two apparently independent risk factors: the body mass index (OR=1,1) and an association between snoring and increased vigilance trouble (OR=2,6). No statistical difference was found concerning IGR. CONCLUSIONS: SAS symptoms are frequent during pregnancy and snoring appears to be linked with PIH. However, polysomnographic data are not yet sufficient to explain pathophysiological mechanisms and find relevant diagnostic markers during pregnancy.

RESUMEN

Patients under 5 years were not evaluated in the phase-3 study for enzyme replacement therapy (ERT) in MPS IV A. Here we describe the evolution of a severe Morquio A pediatric patient who was diagnosed at 19 months old and treated by ERT at 21 months old for the next 30 months. Applying the standard ERT protocol on this very young patient appeared to reduce his urinary excretion of glycosaminoglycans (GAGs); the improvements in both the 6 minute-walk test (6MWT) and the stair climb test, however, were no different than those reported in the nature history study. Additionally, this young patient experienced many ERT-associated side effects, and as a result a specific corticosteroid protocol (1 mg/kg of betamethasone the day before and 1 h before the ERT infusion) was given to avoid adverse events. Under these treatments, the height of this patient increased during the first year of the ERT although no more height gain was observed thereafter for 18 months. However, despite of ERT, his bone deformities (including severe pectus carinatum) actually worsened and his medullar cervical spine compression showed no improvement (thus needed decompression surgery). CONCLUSION: early ERT treatment did not improve the bone outcome in this severe MPS IV A patient after the 30 months-long treatment. A longer term follow up is required to further assess the efficacy of ERT on both the motor and the respiratory function of the patient.
