Full textBackground and purpose: Myotonic dystrophy (DM) is the most common dystrophy in adults. It is an autosomal dominant disease characterized by a variety of multisystemic features. Myotonic dystrophy type 1 (DM1) is caused by trinucleotide expansion of CTG in the myotonic dystrophy protein kinase gene. Clinical manifestations of DM1 include respiratory disorders. The goals of this study were to evaluate the prevalence and the severity of respiratory disorders in DM1 patients at diagnosis and to assess the awareness of the patients about the disease and the respiratory condition. Patients and Methods: Consecutive patients with a genetically confirmed diagnosis of DM1 admitted in Clinica Neurologica of Ancona from September 2007 to October 2010 were enrolled at diagnosis. Patients underwent general and neurological physical examination, ophthalomological assessment, chest X-ray and electromyography (EMG). We analysed the clinical features of patients, the reason that led to diagnosis, the presence of symptoms suggestive of a respiratory disorder (such as fatigue, dyspnea, morning headache, etc). Nocturnal cardiorespiratory monitoring as well as spirometry and blood gases were performed in all DM1 patients. Myotonia and muscle weakness were rated using the five point muscular disability rating scale (MDRS) and excessive daytime sleepness was assessed by the Epworth Sleepiness Scale (ESS). Were regarded as suffering from impaired lung function, patients who had at least one of the following: daytime PaCO2 ≥ 45 mm Hg, forced vital capacity (FVC) <80% predicted, AHI> 10 events per hour of sleep, SaO2 <90% for ≥ 5% of the night. Indication for Noninvasive Positive Pressure Ventilation (NIV) was one of PaCO2 ≥ 45 mm Hg, nocturnal oxygen saturation ≤ 88% for 5 consecutive minutes, FVC< 50% predicted. Results: Data were collected on 21 patients (11 female/10 male), mean age 39,7 years (range 19-61 years). EMG revealed typical myotonic changes in all patients. None of the patients had chest deformity. The reason that led to diagnosis of DM1 was the presence of a sick relative in 7 cases (33.35%), the myotonic phenomenon in 3 (14.3%), detection of iperCKemia to blood tests in 2 (9, 5%), weakness in 7 (33.35%) and other reasons (headache and dizziness) in 2 (9.5%). One third of patients appeared to have normal blood gases, spirometry and nocturnal parameters while the remaining 66,7% had impaired lung function. The impaired lung function test was just the nocturnal cardiorespiratory monitoring in one patient (5%), just the spirometry in two patients (10%), blood gases and nocturnal cardiorespiratory monitoring in one patient (5%), blood gases and spirometry in three patients (15%), spirometry and nocturnal cardiorespiratory monitoring in three patients (15%), all three tests in 4 patients (20%). Of the 14 subjects with impaired respiratory function 9 had a so severe situation to met the criteria for NIV. Only four of the 21 patients properly interrogated reported symptoms suggestive of impaired lung function. One of these patients had no impairment of lung function. Conclusions: We enrolled 21 DM1 patients in three years. Probably the incidence of DM1 in our region is significantly higher than expected according to the literature. The majority of the patients enrolled had evidence of impaired lung function. No significant relationships were found between subjective complaints, clinical-demographic features and respiratory compromission (p>0.005). Timely recognition of a respiratory compromission may lead to improved survival and quality of life by the application of non-invasive ventilatory support. Importance of monitoring respiratory function in patients with DM1 is designed to avoid emergency procedures such as intubation. In relation to the heterogeneity of respiratory involvement features, all the three pneumological tests should be performed in all DM1 patients from the time of diagnosis. The guidelines regarding the indication for NIV don't take into account the differences that exist between the various neuromuscular diseases, is therefore necessary to draw up specific guidelines for each neuromuscular disease and in particular for DM1.

Full textBackground: sleep related breathing disorders (SRBD) are highly prevalent among congestive heart failure (CHF) patients, as indicated by the previously published ProMISeS-I study. Despite the well-known prognostic significance of SRBD in CHF patients, only few studies have performed a detailed characterization of different types of SRBD among these subjects. Aim: The aims of the present analysis, conducted in a large population of CHF patients were: 1) To explore the characteristics and prevalence of different SRBD, 2) To explore possible associations between SRBD (Outcome) and demografic, clinical characteristics (predictors). Materials and methods: A total of 830 CHF patients were consecutively enrolled in the frame of the multicentric ProMISeS-II project between february 2014 and february 2017. In all participants demographic and echocardiographic data were available for analyses. Cardio-respiratory polysomnography was performed and its results interpreted according to 2007 AASM recommendations. According to ventilatory patterns and considering an AHI ≥5 events/hour, subjects were classified into 5 different categories: 1) Prevalent Obstructive Sleep Apnea (pOSA OAHI/AHI > 0.5); 2) Prevalent Central Sleep Apnea (pCSA, CAHI/AHI > 0.5); 3) Prevalent hypopnea (pHY, HY/AHI > 0.5), 4) Mixed ventilatory pattern (pMIX) without a neat prevalence of any of the former patterns; and 5) Absence of ventilatory alterations during sleep (No SRBD, AHI < 5). The association between SRBD and their potential predictors was explored by means of generalized linear models (GLM). Results: The final cohort of the study consisted of 656 CHF patients, mostly men (n=578, 88%), mean age 65 ±11 years, median BMI 27.8 (25.2-31.1 IQR). Main identifiable causes of CHF were ischemic (56%), idiopatic (26%), other causes (11%), hypertensive (4%), and valvular (4%). An EF <40% was present in 81% of patients and atrial fibrillation was present in about 25%. The Median AHI was 21 [6 – 37.6 IQR] and the global prevalence of SRBD was 78%. Prevalence (RP) was also estimated for specific SRBDs: i) pOSA (14% n 93), ii) pCSA (23% n 153), iii) pHY (28% n 186) and v) pMIX (12% n 77). Of note, the relative prevalence of pHI (PR 1.59, 95%IC 1.17-2.17) and pCSA (PR 2.28, 95%IC 1.44-3.63) was significantly higher in men compared to women. No gender-related differences in the prevalence of pOSA nor in pMIX, were observed. In linear generalized models age was directly associated with the prevalence of all types SRBD but pOSA. In particular, each year increase in age was associated with a variable increase in the prevalence of SRBD ranging from 1% for pHI to 4% for pMIX. An unexpected result of our study regards the association of sedentarism (prevalence of 50% in our study population) with SRBDs. Compared to non-sedentary subjects, a lower relative prevalence of SRBDs was observed among sedentary subjects being 0.70 (95% IC 0.58-0.84) for pHI, 0.22 (95%IC 0.12-0.39) for pMIX, and 0.52 (95%IC 0.41-0.67) for pCSA. When evaluating the relationship between body weight and SRBDs, each unit increase in BMI was associated with a variable increase in the prevalence of SRBDs (ranging from 1% for pCSA to 4% for pMIX). Finally, the prevalence of pMIX (RP 1.37, 95%IC 1.06-1.78) and pCSA (RP 1.38, 95%IC 1.14-1.68) was significantly higher among patients with atrial fibrillation, and the prevalence of pCSA was higher (RP 1.41, 95% CI 1.09-1.82) among patients with an EF < 40%. Conclusions: the present analysis (ProMISeS-II study), conducted in a higher number of subjects (n=656) compared to the first report of the ProMISeS-I study (n=370), comfirms the extremely high prevalence of SRBD among CHF patients. In the present report SRBDs have been better characterized by identifying not only classical phenotypes such as pCSA e pOSA, but also assessing two additional categories namely pHI and mixed ventilatory patterns.

Full textBackground: Obstructive sleep apnea (OSA) is currently undertaken to impair ischemic stroke risk especially by intracranial pressure, blood flow, glucose metabolism, atherogenesis, blood coagulation, cardiac arrhythmia and arterial hypertension. In OSA patients hypertension is often related to drug resistance and modification in nocturnal blood pressure profile. In stroke patients with OSA has been observed an impairment of functional outcome. About OSA and intra cranial haemorrhage (ICH) few data are available in literature and most of them are anecdotal. We can speculate that OSA can affect on ICH by arterial hypertension. Methods: in this study we sought to test whether suspected OSA is more prevalent in ICH group than in control. In order to limit potential confounding variables associated with acute ICH, we tested by Berlin Questionnaire (BQ) and Epworth Sleepiness Scale (ESS) referring to the previous 3 months before ICH. Secondarily, we tried to assess if OSA in ICH could affect on functional outcome (mRS) like disability or mortality, as described in ischemic stroke. For these purposes we recruited 111 ICH patients matched by sex, age, Body Mass Index (BMI) and Charlson Comorbidity Index (CCI) with 111 ischemic stroke patients and 111 controls. Results: In ICH patients we found BQ positivity in 30,6% vs 25,2% in ischemic stroke patients vs 13,5% in controls (p 0.01). Moreover BQ positive ICH patients had more disability, mortality, length of recovery, arterial hypertension, drug resistance hypertension and nocturnal blood pressure profile alteration, especially non dipper pattern, than BQ negative ICH. Conclusion: The results suggest that OSA can be considered a risk factor and a negative prognostic factor in ICH patients, as described before in ischemic stroke patients. Moreover we can considered this fenomena probably related to blood pressure alteration caused by sleep breathing disorder.

Full textBackground: sleep disordered breathing (obstructive and central sleep apnea)(SDB) may contribute to progression of congestive heart failure (CHF) and may exert pro-arrhythmic effects by eliciting greater sympathetic outflow to the heart, kidney and resistence vessels, by inducing production of proinflammatory mediators and by direct mechanical stimulation of the myocardium; persistent activation of the neuroendocrine system, notably adrenergic and neurohormonal systems, is maladaptative in heart failure and Cromogranin A (CgA) may represent a marker of enhanced neuroendocrine activity in CHF due to comorbid sleep apnea. Hypothesis: to investigate the prevalence of SDB in CHF patients; to determine whether SDB is a risk factor for acute heart failure decompensation and life-threatening ventricular arrhythmia in patients with CHF; to evaluate if CHF patients with SDB have augmented circulating levels of CgA compared to patients without sleep apnea. Methods: 82 consecutive patients with CHF and reduced left ventricular ejection fraction (LVEF<40%) were screened for SDB by unattended nocturnal poligraphy; the Apnea-Hypopnea Index (AHI) was defined as the number of apneas-hypopneas per hour of sleep; patients with an AHI ≥10 events/hour were considered as affected by SDB. 56 patients with stable CHF on optimal medical therapy were included in a prospective study to determine the incidence of acute heart failure decompensation during a median follow-up of 18 months; 46 patients were implanted with a cardiac resinchronization device with cardioverter defibrillator (CRT-ICD) 6 months before inclusion into the cohort and were further studied to collect data on appropriate device interventions and appropriately monitored life-threatening ventricular arrhythmias. Serum CgA was measured in 50 patients throughout the entire course of the study. Results: SDB was diagnosed in 49 out of 82 patients (59,8%). The prevalence of obstructive and central sleep apnea was 37,8% and 22% respectively. Kaplan Meier survival estimates showed a reduced acute heart failure free survival in patients with SDB compared to no SDB patients ( 15 vs 24 months, logrank test p=0,03). On multivariate Cox proportional hazard model SDB was independently associated to a 2,86 fold increased hazard ratio (HR) for acute heart failure (95% CI: 1,09-7,52; p=0,03); atrial fibrillation showed to be a predictor for heart failure decompensation after accounting for the presence of SDB and other confounding factors (HR: 3,14; 95% CI: 1,28-7,70 p=0,01). Malignant ventricular arrhythmia was detected or treated by ICD in 24 out of 46 patients (52%) and SDB was present in 75% of these patients compared to 41% of patients with no detected arrhythmia (p=0,01). Time period to first life threatening arrhythmia was significantly shorter in patients with SDB (logrank test p=0,01); multivariate stepwise cox models revealed an independent correlation for severity of SDB (AHI> 22 vs ≤ 22 events/hour) regarding monitored or treated ventricular arrhythmia (HR 3,53; 95%CI: 1,49-8,64; p=0,006) in primary prevention CHF patients. Serum CgA levels were elevated in patients with AHI>22 ev/h compared to patients with mild or no sleep apnea (165,3 ± 39,6 ng/mL and 72,8 ± 9,4, respectively); on multiple regression analysis AHI was correlated to CgA circulating levels after accounting for LVEF and NYHA class (r=0,377; p<0,01). Conclusions: sleep disordered breathing is an highly prevalent comorbidity in patients with systolic heart failure and is independently associated with an increased risk of heart failure decompensation and malignant ventricular arrhythmia in patients on optimal medical therapy treated with cardiac resinchronization. CgA circulating levels are elevated in CHF patients with AHI>22 ev/h and may represent neuroendocrine activity elicited by sleep apnea.
