The inspiratory part of the flow-volume curve (F-V curve) can be used as an auxiliary means to evaluate upper airway obstruction in adults. This study is to evaluate the ability of the F-V curve to predict the OSA and explore inspiratory indicators related to airway obstruction during sleep. Methods: There were 332 patients included in this cross-sectional study, who were accompanied by snoring, daytime sleepiness and other symptoms, with suspicion of OSA. According to the nocturnal polysomnography, the subjects were distributed into mild to moderate OSA group, severe OSA group and non-OSA group. A pulmonary function test was used to collect the subjects’ spirometry and F-V curves. Results: There was no significant difference in a variety of indices derived from the F-V curve between OSA and normal subjects, including 25% inspiratory flow rate, middle inspiratory flow rate, 75% inspiratory flow rate, peak flow rate, and forced inspiratory flow rate in the first second. The pulmonary function parameters were significantly correlated with the weight, age and sex of the subjects. Conclusion: These findings suggest that the inspiratory curve of pulmonary function cannot evaluate the upper airway abnormalities in patients with obstructive apnea-hypopnea syndrome.展开更多

Their blood samples were drawn at 6∶00 and 16∶00 respectively for testing hemocrit, platelet aggregation (PAG), whole blood viscosity (WBV), prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (Fng) and endothelin (ET).Results: There was a significantly higher hemocrit, WBV, Fng and ET as well as a significant shortening of PT and APTT at 6∶00 than that at 16∶00 in OSAHS group. However, there was no significant difference in all testing items between 6∶00 and 16∶00 in control group. The hemocrit, WBV, PAG, plasma Fng and ET were significantly higher, and PT and APTT were obviously shorter at 6∶00 in OSAHS group than those at 6∶00 in control group. A higher hemocrit, PAG, plasma Fng and ET, a longer PT and APTT were observed at 16∶00 in OSAHS group, compared with those at 16∶00 in control group.Conclusion: In OSAHS patients there were striking risk factors of thrombosis, which is more remarkable in the early morning than in the afternoon.展开更多

Methods:Twenty-eight male OSAHS patients and 14 normal males（as controls） were enrolled in the study.Polysomnography and the Montreal cognitive assessment（MoCA） were conducted. The blood serum BDNF levels were measured using ELISA.Results:The OSAHS group had significantly decreased blood serum BDNF levels compared with the control group（t=-10.912, P=0.000）.The blood serum BDNF level of the subjects was significantly positively associated with the MoCA score（r=0.544,P=0.000）,significantly negatively associated with the apneahypopnea index（AHI） and shallow sleep（S1+S2）（AHI:r=-0.607,P=0.000;S1+S2:r =-0.768,P= 0.000）,and significantly positively associated with the lowest SaO<sub>2</sub>（LSO）,slow wave sleep（S3+S4）, and rapid eye movement sleep（REM）（LSO:r=0.566,P = 0.000;S3+S4:r=0.778,P=0.000;REM: r=0.575,P=0.000）.Conclusions:OSAHS patients have significantly decreased blood serum BDNF levels compared with the control.Nocturnal hypoxia as well as the deprivation of slow wave sleep and REM may lead to the decreased serum BDNF level of OSAHS patients.This decreased blood serum BDNF level may contribute to the cognitive impairment in OSAHS.展开更多

However, changes of homocysteine （Hey） as markers of cardiovascular and eerebrovascular disease associated with OSAHS and their mechanism have not been elucidated so far. This study aims to investigate the changes of both serum Hcy and oxidative stress and their possible links with OSAHS in elderly patients. Methods Based on polysomnogram （PSG） and age, 83 patients with OSAHS were recruited and divided into elderly-OSAHS （n=32） and non-elderly OSAHS groups （n=51）. Fifty two subjects without OSAHS were divided into elderly control （n=29） and non-elderly control groups （n-23）. A total of 135 subjects were included in the present study. All subjects were recorded for PSG variables and the contents of homocysteine （Hcy）, malonaldehyde （MDA）, and glutathione （GSH） which were detected after sleep. Serum homocysteine was measured by cyclophorase. MDA and GSH were measured by speetrophotometer. Results （1） The serum levels of Hcy showed significant difference among the four groups （P〈0.05）. The concentrations of Hcy in elderly OSAHS patients were higher than in other groups, while those in the elderly control group were higher than in the non-elderly control; the concentrations in the non-elderly OSAHS group were higher than in the non-elderly control. （2） The concentrations of MDA and GSH changed at an equal pace with Hcy in the four groups. （3） Multielement linearity regression analysis indicated a statistically significant relationship between Hcy concentration and age, MDA, GSH, and apnea hypopnea index （AHI）. Conclusions （1） The concentrations of Hcy and oxidative stress have increased with advancing age. （2） The concentrations of Hcy and oxidative stress have further increased in the elderly patients with OSAHS. （3） Oxidative stress might cause high-level serum Hcy in the elderly patients with OSAHS.展开更多

Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment. The results revealed that as the disease worsened, the mismatch negativity latency was gradually extended, and the amplitude gradually declined in patients with obstructive sleep apnea hypopnea syndrome. Importantly, mismatch negativity latency in severe patients with a persistent time of minimum oxygen saturation 〈 60 seconds was significantly shorter than that with a persistent time of minimum oxygen saturation 〉 60 seconds. Correlation analysis revealed a negative correlation between minimum oxygen saturation latency and Montreal Cognitive Assessment scores. These findings indicate that intermittent night-time hypoxemia affects mismatch negativity waveforms and Montrea Cognitive Assessment scores. As indicators for detecting the cognitive functional status of obstructive sleep apnea hypopnea syndrome patients, the sensitivity of mismatch negativity is 82.93%, the specificity is 73.33%, the accuracy rate is 81.52%, the positive predictive value is 85.00%, the negative predictive value is 70.21%, the positive likelihood ratio is 3, and the negative likelihood ratio is 0.23. These results indicate that mismatch negativity can be used as an effective tool for diagnosis of cognitive dysfunction in obstructive sleep apnea hypopnea syndrome patients.展开更多

METHODS： In this cross-sectional study, potential OSAHS patients at Siriraj Hospital underwent polysomnography to determine the severity of OSAHS and an eye examination （including best corrected visual acuity, slit-lamp examination, and Goldmann applanation tonometry）. RNFL thickness was recorded once in the morning and once in the evening, using spectral domain optical coherence tomography. Thickness was expressed as an average and given for each quadrant. Patients with ocular or systemic diseases that might affect RNFL thickness were excluded. RESULTS： Forty-one eyes of 41 patients were classified into 40SAHS groups. The average and mean RNFL thickness in most of the four quadrants of the severe OSAHS group trended toward being less than those in the comparable quadrants of the other groups in both the morning and evening. In the moderate OSAHS group, the average RNFL thickness and temporal and superior quadrant thickness in the morning were significantly higher than in the evening （P=0.01, P=0.01, and P=0.03, respectively）. In the severe OSAHS group, the inferior quadrant thickness in the morning was significantly higher than in the evening （P =0.03）. CONCLUSION： The RNFL thickness in the morning was higher than in the evening in moderate OSAHS.展开更多

Meanwhile the correlation between the concentration of VEGF and parameters of polysomnography （PSG） was examined. Our results showed that the concentrations of VEGF were significantly higher in OSAHS patients with severe hypoxia （536.8±334.7 pg/mL） than in those with mild hypoxia （329.2±174.7 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. The concentrations of VEGF were also significantly higher in OSAHS patients with hypertension （484.5±261.4 pg/mL） than in those without hypertension （311.0±158.4 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. There was a positive correlation between the concentration of VEGF and the apnea hypopnea index （AHI） （r=0.34, P〈0.05）. It is concluded that the concentration of the serum VEGF is positively related to the severity of OSAHS. The elevated serum VEGF level may be involved in the pathogenesis of the complications of obstructive sleep apnea hypopnea syndrome.展开更多

Methods： With the use of polysomnography, 262 adult habitual snorers were examined and divided into the OSAHS group and the Non-OSAHS group （control）. Using ambulatory electrocardiogram and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrythmias and angina pectoris of coronary heart disease were monitored and compared between the two groups, before and after 14 days of treatment with NCPAP in the OSAHS group. Results.This study indicated a higher incidence （39.6%） of OSAHS in adult snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance of the daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrythmias and lower SpO2 levels in the OSAHS group than in the Non-OSAHS group. After NCPAP treatment during sleep, snoring control, significantly higher SpO2 and lower apnea hypopnea indices were achieved in the OSAHS group; heart rate variability and daily nocturnal rhythm of blood pressure returned to normal levels. Conclusion：The results of this research suggested that there was a close relationship between the development of OSAHS and some cardiovascular disorders. Furthermore, NCPAP treatment was effective not only on OSAHS but also on coexisting cardiovascular disorders.展开更多

Methods Auditory brainstem responses (ABRs) were recorded in 68 ears and distortion product otoacoustic emissions (DPOAEs) in 60 ears in children with OSAHS and type "A" tym-panograms, and in 30 ears in normal children. Results ABR latencies of waves I, III and V, and I-III, III-V and I-V intervals were not statistically different between OSAHS and normal children. Wave I latency was delayed in children with OSAHS compared to normal children3 (P < 0.05). DPOAE amplitudes in children with mild OSAHS were lower than normal children at 8 kHz (P < 0.05). DPOAEs were lower at 6 kHz and 8 kHz in children with moderate/severe OSAHS than normal children (P < 0.05). Conclusion Cochlear function was affected when AHI was at or greater than 10/hour. ABR and DPOAE can be used to detect early changes in auditory function in children with OSAHS.展开更多

One of the ...<strong>Introduction:</strong> Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a frequent pathology worldwide whose main mechanism is a complete or partial obstruction of the upper airway. One of the pathophysiological mechanisms described in primary open-angle glaucoma is that hypoxia in the optic nerve progressively destroys the retinal cells leading to the onset and/or aggravation of glaucoma. The aim of the study was to evaluate the risk of OSA in patients with primary open-angle glaucoma. <strong>Methodology:</strong> An analytical study was conducted from January to May 2020 at the UHC. After obtaining ethical clearance, 112 patients including 50 glaucoma patients (44.64%) and 62 in the control group were enrolled. Sociodemographic and clinical data were collected from the medical records of the participants, with or without glaucoma, and a questionnaire was administered and a clinical examination performed. The STOP BANG score was used to determine the risk level of OSAHS. Statistical analyses were performed using Epi Info version 7.2. <strong>Results:</strong> A female predominance was found (60%) in the glaucoma group with a mean age of 55 ± 17 years against 49 ± 18 years in the control group. The high risk of OSAHS was more associated with glaucoma patients. In glaucoma patients, an association was found between high risk of OSAHS and snoring (OR = [1.43 - 849.53];p = 0.029) as well as insomnia (OR = [1.36 - 482.86];p = 0.030). <strong>Conclusion:</strong> High risk of OSAHS was found in participants with chronic open-angle glaucoma. Signs of OSAHS should be sought in chronic open-angle glaucoma as it may be a factor in its progression.展开更多

Methods： Using the TaqMan polymerase chain reaction（PCR） method, the single nucleotide polymorphisms（SNP） at positions 45 and 276 in the adiponectin gene were determined in Chinese of the Han nationality in the Nanjing district. The OSAHS group consisted of 78 patients, and the control group contained 40 subjects. The association of adiponectin genotype polymorphisms at positions 45 and 276 with obstructive sleep apnea hypopnea syndrome was analyzed. Results： No evidence of a direct association was found between OSAHS and adiponectin genotype SNP at positions 45 and 276（P〉 0.05）. However, compared with those OSAHS patients having G/T＋T/T genotype at position 276, the OSAHS patients with the G/G genotype showed a greater neck circumference（NC）, a prolonged duration of the longest apnea event, and elevated levels of blood cholesterol and low-density lipoprotein cholesterol（P 〈 0.05）. Conclusion： No direct association was detected between OSAHS and adiponectin genotype distribution at positions 45 and 276 in Chinese of Han nationality in the Nanjing district. However, OSAHS patients with the adiponectin G/G genotype at position 276 had a larger NC and the longest apnea event compared to those having the adiponectin SNP276 G/T ＋T/T genotype. This may have an indirect influence on the development of OSAHS,展开更多

Rheumatoid arthritis (RA) is a systemic disease contributing to hyperplasia of synovial membrane, cartilage erosion and joint damage. Fibroblast like synoviocytes (FLS), which make up the lining of the synovial membrane, are believed to play a role in the pathogenesis of RA. RA is a series of inflammation-like responses that induce joint damage and dysfunction and impair patients' life quality. This article first introduced the basic features of RA and analyzes the pathogenesis of RA with SAHS. Then the relationship between RA and SAHS was investigated. Finally, the progress in the treatment for RA with SAHS was reviewed emphatically.展开更多

文摘BACKGROUND Despite being one of the most prevalent sleep disorders,obstructive sleep apnea hypoventilation syndrome(OSAHS)has limited information on its immunologic foundation.The immunological underpinnings of certain major psychiatric diseases have been uncovered in recent years thanks to the extensive use of genome-wide association studies(GWAS)and genotyping techniques using highdensity genetic markers(e.g.,SNP or CNVs).But this tactic hasn't yet been applied to OSAHS.Using a Mendelian randomization analysis,we analyzed the causal link between immune cells and the illness in order to comprehend the immunological bases of OSAHS.AIM To investigate the immune cells'association with OSAHS via genetic methods,guiding future clinical research.METHODS A comprehensive two-sample mendelian randomization study was conducted to investigate the causal relationship between immune cell characteristics and OSAHS.Summary statistics for each immune cell feature were obtained from the GWAS catalog.Information on 731 immune cell properties,such as morphologic parameters,median fluorescence intensity,absolute cellular,and relative cellular,was compiled using publicly available genetic databases.The results'robustness,heterogeneity,and horizontal pleiotropy were confirmed using extensive sensitivity examination.RESULTS Following false discovery rate(FDR)correction,no statistically significant effect of OSAHS on immunophenotypes was observed.However,two lymphocyte subsets were found to have a significant association with the risk of OSAHS:Basophil%CD33dim HLA DR-CD66b-(OR=1.03,95%CI=1.01-1.03,P<0.001);CD38 on IgD+CD24-B cell(OR=1.04,95%CI=1.02-1.04,P=0.019).CONCLUSION This study shows a strong link between immune cells and OSAHS through a gene approach,thus offering direction for potential future medical research.
文摘Objective: Obstructive sleep apnea-hypopnea syndrome (OSA) is a disease of obstructive apnea or hypopnea caused by a repeated partial or complete collapse of the upper airway during sleep. The inspiratory part of the flow-volume curve (F-V curve) can be used as an auxiliary means to evaluate upper airway obstruction in adults. This study is to evaluate the ability of the F-V curve to predict the OSA and explore inspiratory indicators related to airway obstruction during sleep. Methods: There were 332 patients included in this cross-sectional study, who were accompanied by snoring, daytime sleepiness and other symptoms, with suspicion of OSA. According to the nocturnal polysomnography, the subjects were distributed into mild to moderate OSA group, severe OSA group and non-OSA group. A pulmonary function test was used to collect the subjects’ spirometry and F-V curves. Results: There was no significant difference in a variety of indices derived from the F-V curve between OSA and normal subjects, including 25% inspiratory flow rate, middle inspiratory flow rate, 75% inspiratory flow rate, peak flow rate, and forced inspiratory flow rate in the first second. The pulmonary function parameters were significantly correlated with the weight, age and sex of the subjects. Conclusion: These findings suggest that the inspiratory curve of pulmonary function cannot evaluate the upper airway abnormalities in patients with obstructive apnea-hypopnea syndrome.
文摘Objective: To observe the risk factors of thrombosis in patients with obstructive sleep apnea hypopnea syndrome (OSAHS).Methods: From February 2001 to April 2003, 24 patients with moderate and severe OSAHS (OSAHS group) and 19 healthy adults (control group) were recruited. Their blood samples were drawn at 6∶00 and 16∶00 respectively for testing hemocrit, platelet aggregation (PAG), whole blood viscosity (WBV), prothrombin time (PT), activated partial thromboplastin time (APTT), plasma fibrinogen (Fng) and endothelin (ET).Results: There was a significantly higher hemocrit, WBV, Fng and ET as well as a significant shortening of PT and APTT at 6∶00 than that at 16∶00 in OSAHS group. However, there was no significant difference in all testing items between 6∶00 and 16∶00 in control group. The hemocrit, WBV, PAG, plasma Fng and ET were significantly higher, and PT and APTT were obviously shorter at 6∶00 in OSAHS group than those at 6∶00 in control group. A higher hemocrit, PAG, plasma Fng and ET, a longer PT and APTT were observed at 16∶00 in OSAHS group, compared with those at 16∶00 in control group.Conclusion: In OSAHS patients there were striking risk factors of thrombosis, which is more remarkable in the early morning than in the afternoon.

文摘Objective:To determine the relationship between the blood serum brain-derived neurotrophic factor（BDNF） level and cognitive function deterioration in patients with obstructive sleep apnea/ hypopnea syndrome（OSAHS）,and to explore the possible mechanism of cognitive impairment. Methods:Twenty-eight male OSAHS patients and 14 normal males（as controls） were enrolled in the study.Polysomnography and the Montreal cognitive assessment（MoCA） were conducted. The blood serum BDNF levels were measured using ELISA.Results:The OSAHS group had significantly decreased blood serum BDNF levels compared with the control group（t=-10.912, P=0.000）.The blood serum BDNF level of the subjects was significantly positively associated with the MoCA score（r=0.544,P=0.000）,significantly negatively associated with the apneahypopnea index（AHI） and shallow sleep（S1+S2）（AHI:r=-0.607,P=0.000;S1+S2:r =-0.768,P= 0.000）,and significantly positively associated with the lowest SaO<sub>2</sub>（LSO）,slow wave sleep（S3+S4）, and rapid eye movement sleep（REM）（LSO:r=0.566,P = 0.000;S3+S4:r=0.778,P=0.000;REM: r=0.575,P=0.000）.Conclusions:OSAHS patients have significantly decreased blood serum BDNF levels compared with the control.Nocturnal hypoxia as well as the deprivation of slow wave sleep and REM may lead to the decreased serum BDNF level of OSAHS patients.This decreased blood serum BDNF level may contribute to the cognitive impairment in OSAHS.

文摘Objective Elderly patients with obstructive sleep apnea/hypopnea syndrome （OSAHS） has a higher risk of cardiovascular and cerebrovascular disease. However, changes of homocysteine （Hey） as markers of cardiovascular and eerebrovascular disease associated with OSAHS and their mechanism have not been elucidated so far. This study aims to investigate the changes of both serum Hcy and oxidative stress and their possible links with OSAHS in elderly patients. Methods Based on polysomnogram （PSG） and age, 83 patients with OSAHS were recruited and divided into elderly-OSAHS （n=32） and non-elderly OSAHS groups （n=51）. Fifty two subjects without OSAHS were divided into elderly control （n=29） and non-elderly control groups （n-23）. A total of 135 subjects were included in the present study. All subjects were recorded for PSG variables and the contents of homocysteine （Hcy）, malonaldehyde （MDA）, and glutathione （GSH） which were detected after sleep. Serum homocysteine was measured by cyclophorase. MDA and GSH were measured by speetrophotometer. Results （1） The serum levels of Hcy showed significant difference among the four groups （P〈0.05）. The concentrations of Hcy in elderly OSAHS patients were higher than in other groups, while those in the elderly control group were higher than in the non-elderly control; the concentrations in the non-elderly OSAHS group were higher than in the non-elderly control. （2） The concentrations of MDA and GSH changed at an equal pace with Hcy in the four groups. （3） Multielement linearity regression analysis indicated a statistically significant relationship between Hcy concentration and age, MDA, GSH, and apnea hypopnea index （AHI）. Conclusions （1） The concentrations of Hcy and oxidative stress have increased with advancing age. （2） The concentrations of Hcy and oxidative stress have further increased in the elderly patients with OSAHS. （3） Oxidative stress might cause high-level serum Hcy in the elderly patients with OSAHS.

文摘In this experiment, 97 patients with obstructive sleep apnea hypopnea syndrome were divided into three groups （mild, moderate, severe） according to minimum oxygen saturation, and 35 healthy subjects were examined as controls. Cognitive function was determined using the mismatch negativity paradigm and the Montreal Cognitive Assessment. The results revealed that as the disease worsened, the mismatch negativity latency was gradually extended, and the amplitude gradually declined in patients with obstructive sleep apnea hypopnea syndrome. Importantly, mismatch negativity latency in severe patients with a persistent time of minimum oxygen saturation 〈 60 seconds was significantly shorter than that with a persistent time of minimum oxygen saturation 〉 60 seconds. Correlation analysis revealed a negative correlation between minimum oxygen saturation latency and Montreal Cognitive Assessment scores. These findings indicate that intermittent night-time hypoxemia affects mismatch negativity waveforms and Montrea Cognitive Assessment scores. As indicators for detecting the cognitive functional status of obstructive sleep apnea hypopnea syndrome patients, the sensitivity of mismatch negativity is 82.93%, the specificity is 73.33%, the accuracy rate is 81.52%, the positive predictive value is 85.00%, the negative predictive value is 70.21%, the positive likelihood ratio is 3, and the negative likelihood ratio is 0.23. These results indicate that mismatch negativity can be used as an effective tool for diagnosis of cognitive dysfunction in obstructive sleep apnea hypopnea syndrome patients.
文摘This study examined the dynamic characteristics of upper airway collapse at soft palate level in patients with obstructive sleep apnea/hypopnea syndrome（OSAHS） by using dynamic 3-Dimensional（3-D） CT imaging.A total of 41 male patients who presented with 2 of the following symptoms,i.e.,daytime sleepiness and fatigue,frequent snoring,and apnea with witness,were diagnosed as having OSAHS.They underwent full-night polysomnography and then dynamic 3-D CT imaging of the upper airway during quiet breathing and in Muller＇s maneuver.The soft palate length（SPL）,the minimal cross-sectional area of the retropalatal region（mXSA-RP）,and the vertical distance from the hard palate to the upper posterior part of the hyoid（hhL） were compared between the two breathing states.These parameters,together with hard palate length（HPL）,were also compared between mild/moderate and severe OSAHS groups.Association of these parameters with the severity of OSAHS [as reflected by apnea hypopnea index（AHI） and the lowest saturation of blood oxygen（LSaO2）] was examined.The results showed that 31 patients had severe OSAHS,and 10 mild/moderate OSAHS.All the patients had airway obstruction at soft palate level.mXSA-RP was significantly decreased and SPL remarkably increased during Muller＇s maneuver as compared with the quiet breathing state.There were no significant differences in these airway parameters（except the position of the hyoid bone） between severe and mild/moderate OSAHS groups.And no significant correlation between these airway parameters and the severity of OSAHS was found.The position of hyoid was lower in the severe OSAHS group than in the mild/moderate OSAHS group.The patients in group with body mass index（BMI）≥26 had higher collapse ratio of mXSA-RP,greater neck circumference and smaller mXSA-RP in the Muller＇s maneuver than those in group with BMI26（P0.05 for all）.It was concluded that dynamic 3-D CT imaging could dynamically show the upper airway changes at soft palate level in OSAHS patients.All the OSAHS patients had airway obstruction of various degrees at soft palate level.But no correlation was observed between the airway change at soft palate level and the severity of OSAHS.The patients in group with BMI≥26 were more likely to develop airway obstruction at soft palate level than those with BMI26.

文摘AIM： To compare the retinal nerve fiber layer （RNFL） thickness in the morning and evening in Thai patients with varying degrees of obstructive sleep apnea/ hypopnea syndrome （OSAHS）. METHODS： In this cross-sectional study, potential OSAHS patients at Siriraj Hospital underwent polysomnography to determine the severity of OSAHS and an eye examination （including best corrected visual acuity, slit-lamp examination, and Goldmann applanation tonometry）. RNFL thickness was recorded once in the morning and once in the evening, using spectral domain optical coherence tomography. Thickness was expressed as an average and given for each quadrant. Patients with ocular or systemic diseases that might affect RNFL thickness were excluded. RESULTS： Forty-one eyes of 41 patients were classified into 40SAHS groups. The average and mean RNFL thickness in most of the four quadrants of the severe OSAHS group trended toward being less than those in the comparable quadrants of the other groups in both the morning and evening. In the moderate OSAHS group, the average RNFL thickness and temporal and superior quadrant thickness in the morning were significantly higher than in the evening （P=0.01, P=0.01, and P=0.03, respectively）. In the severe OSAHS group, the inferior quadrant thickness in the morning was significantly higher than in the evening （P =0.03）. CONCLUSION： The RNFL thickness in the morning was higher than in the evening in moderate OSAHS.
文摘BACKGROUND Childhood obstructive sleep apnea hypopnea syndrome(OSAHS)is a common clinical disease that can cause serious complications if not treated in time.The preferred treatment for OSAHS in children is surgery.AIM To observe the effects of soft palate-pharyngoplasty on postoperative outcome,pharyngeal formation,and possible complications.METHODS A total of 150 children with snoring,hernia,and mouth breathing were selected.A polysomnography test was performed to confirm the diagnosis of OSAHS.The children were randomly divided into experimental and control groups.The experimental group underwent adenoidectomy,tonsillectomy,and soft palatepharyngoplasty.The control group underwent adenoidectomy and tonsillectomy.The t-test and chi-square test were used to compare conditions such as postoperative fever,postoperative hemorrhage,and pharyngeal reflux.Postoperative efficacy and complications were interrogated and observed in the form of outpatient follow-up and telephone follow-up at 6 mo and 1 year after surgery.The curative effects were divided into two groups:Cure(snoring,snoring symptoms disappeared)and non-cure.RESULTS The effective rate of the experimental group was significantly higher than that of the control group,but the difference was not statistically significant(P>0.05).The incidence of postoperative bleeding was lower in the experimental group.There was no postoperative pharyngeal reflux in either group.In the experimental group,the incidence of hyperthermia(body temperature exceeded 38.5°C)was lower than that in the control group.The difference in postoperative swallowing pain scores between the experimental and control groups was significant.CONCLUSION Soft palate-pharyngoplasty can more effectively enlarge the anteroposterior diameter and transverse diameter of the isthmus faucium.Compared with surgery alone,it can better treat OSAHS in children,improve the curative effect,reduce the risk of perioperative bleeding,close the surgical cavity,reduce the risk of postoperative infection,reduce the proportion of postoperative fever,and accelerate healing.Although this process takes more time,it is simple,safe,and effective.
文摘Though obstructive sleep apnea hypopnea syndrome（OSAHS） and metabolic syndrome（MS） are correlated;the contributing factors for the occurrence of MS in Chinese snorers remain largely undefined.We aimed to investigate the associated pathogenesis of coexistence of OSAHS and MS in Chinese snorers.A total of 144 Chinese habitual snorers were divided into 3 groups,the control group（simple snorers）（n = 36）,the mild OSAHS group（n= 52）and the moderate-to-severe OSAHS group（n = 56）.The incidence of MS in the moderate-to-severe OSAHS group（26.8%） was significantly higher than that in the control group（8.3%）,the mild OSAHS group（11.1%） and all the OSAHS patients（19.45%）（all P 〈 0.05）.Homeostatic model assessment（HOMA） index and proinsulin（PI） were negatively correlated with nocturnal meanSpO2 and miniSpO2.Meanwhile,nocturnal SpO2 were negatively correlated with body mass index,waist and neck circumferences and diastolic blood pressure,but positively correlated with total cholesterol and high-density lipoprotein cholesterol.The study indicated that in Chinese snorers,moderate-to-severe OSAHS was closely associated with MS via nocturnal hypoxemia.
文摘To explore the relationship between the serum vascular endothelial growth factor （VEGF） level and the severity of obstructive sleep apnea hypopnea syndrome （OSAHS）, the concentrations of serum VEGF in 40 OSAHS patients and 9 healthy controls were measured by using ELISA method. Meanwhile the correlation between the concentration of VEGF and parameters of polysomnography （PSG） was examined. Our results showed that the concentrations of VEGF were significantly higher in OSAHS patients with severe hypoxia （536.8±334.7 pg/mL） than in those with mild hypoxia （329.2±174.7 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. The concentrations of VEGF were also significantly higher in OSAHS patients with hypertension （484.5±261.4 pg/mL） than in those without hypertension （311.0±158.4 pg/mL） and healthy controls （272. 8±211.0 pg/mL） （P〈0.05 for both）. There was a positive correlation between the concentration of VEGF and the apnea hypopnea index （AHI） （r=0.34, P〈0.05）. It is concluded that the concentration of the serum VEGF is positively related to the severity of OSAHS. The elevated serum VEGF level may be involved in the pathogenesis of the complications of obstructive sleep apnea hypopnea syndrome.
文摘Objective：To investigate the relationship between sleep apnea hypopnea syndrome（OSAHS） and some cardiovascular disorders in adult habitual snorers as well as the effectiveness of nasal continuous positive airway pressure（NCPAP） on those with OSAHS. Methods： With the use of polysomnography, 262 adult habitual snorers were examined and divided into the OSAHS group and the Non-OSAHS group （control）. Using ambulatory electrocardiogram and blood pressure measurement, daily nocturnal rhythm of blood pressure, hypertension, heart rate variability, some arrythmias and angina pectoris of coronary heart disease were monitored and compared between the two groups, before and after 14 days of treatment with NCPAP in the OSAHS group. Results.This study indicated a higher incidence （39.6%） of OSAHS in adult snorers and demonstrated that there was a significantly higher incidence of hypertension, disappearance of the daily nocturnal rhythm of blood pressure, poor effectiveness of nitrate on angina pectoris of coronary heart disease, decreased heart rate variability during sleep, increased arrythmias and lower SpO2 levels in the OSAHS group than in the Non-OSAHS group. After NCPAP treatment during sleep, snoring control, significantly higher SpO2 and lower apnea hypopnea indices were achieved in the OSAHS group; heart rate variability and daily nocturnal rhythm of blood pressure returned to normal levels. Conclusion：The results of this research suggested that there was a close relationship between the development of OSAHS and some cardiovascular disorders. Furthermore, NCPAP treatment was effective not only on OSAHS but also on coexisting cardiovascular disorders.
文摘Objective To explore the relationship between hypoxemia and hearing in children with obstructive sleep apnea-hypopnea syndrome. Methods Auditory brainstem responses (ABRs) were recorded in 68 ears and distortion product otoacoustic emissions (DPOAEs) in 60 ears in children with OSAHS and type "A" tym-panograms, and in 30 ears in normal children. Results ABR latencies of waves I, III and V, and I-III, III-V and I-V intervals were not statistically different between OSAHS and normal children. Wave I latency was delayed in children with OSAHS compared to normal children3 (P < 0.05). DPOAE amplitudes in children with mild OSAHS were lower than normal children at 8 kHz (P < 0.05). DPOAEs were lower at 6 kHz and 8 kHz in children with moderate/severe OSAHS than normal children (P < 0.05). Conclusion Cochlear function was affected when AHI was at or greater than 10/hour. ABR and DPOAE can be used to detect early changes in auditory function in children with OSAHS.
文摘<strong>Introduction:</strong> Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a frequent pathology worldwide whose main mechanism is a complete or partial obstruction of the upper airway. One of the pathophysiological mechanisms described in primary open-angle glaucoma is that hypoxia in the optic nerve progressively destroys the retinal cells leading to the onset and/or aggravation of glaucoma. The aim of the study was to evaluate the risk of OSA in patients with primary open-angle glaucoma. <strong>Methodology:</strong> An analytical study was conducted from January to May 2020 at the UHC. After obtaining ethical clearance, 112 patients including 50 glaucoma patients (44.64%) and 62 in the control group were enrolled. Sociodemographic and clinical data were collected from the medical records of the participants, with or without glaucoma, and a questionnaire was administered and a clinical examination performed. The STOP BANG score was used to determine the risk level of OSAHS. Statistical analyses were performed using Epi Info version 7.2. <strong>Results:</strong> A female predominance was found (60%) in the glaucoma group with a mean age of 55 ± 17 years against 49 ± 18 years in the control group. The high risk of OSAHS was more associated with glaucoma patients. In glaucoma patients, an association was found between high risk of OSAHS and snoring (OR = [1.43 - 849.53];p = 0.029) as well as insomnia (OR = [1.36 - 482.86];p = 0.030). <strong>Conclusion:</strong> High risk of OSAHS was found in participants with chronic open-angle glaucoma. Signs of OSAHS should be sought in chronic open-angle glaucoma as it may be a factor in its progression.

文摘Objective： To investigate the relationship between adiponectin genotype polymorphisms and obstructive sleep apnea hypopnea syndrome （OSAHS）. Methods： Using the TaqMan polymerase chain reaction（PCR） method, the single nucleotide polymorphisms（SNP） at positions 45 and 276 in the adiponectin gene were determined in Chinese of the Han nationality in the Nanjing district. The OSAHS group consisted of 78 patients, and the control group contained 40 subjects. The association of adiponectin genotype polymorphisms at positions 45 and 276 with obstructive sleep apnea hypopnea syndrome was analyzed. Results： No evidence of a direct association was found between OSAHS and adiponectin genotype SNP at positions 45 and 276（P〉 0.05）. However, compared with those OSAHS patients having G/T＋T/T genotype at position 276, the OSAHS patients with the G/G genotype showed a greater neck circumference（NC）, a prolonged duration of the longest apnea event, and elevated levels of blood cholesterol and low-density lipoprotein cholesterol（P 〈 0.05）. Conclusion： No direct association was detected between OSAHS and adiponectin genotype distribution at positions 45 and 276 in Chinese of Han nationality in the Nanjing district. However, OSAHS patients with the adiponectin G/G genotype at position 276 had a larger NC and the longest apnea event compared to those having the adiponectin SNP276 G/T ＋T/T genotype. This may have an indirect influence on the development of OSAHS,
文摘Objective:Sleep apnea hypopnea syndrome (SAHS) is a common sleep disorder, which is manifested as a reduction in tidal volume or apnea during sleep, which results in intermittent hypoxia and tissue hypoxia and induces oxidative stress and inflammatory responses. Rheumatoid arthritis (RA) is a systemic disease contributing to hyperplasia of synovial membrane, cartilage erosion and joint damage. Fibroblast like synoviocytes (FLS), which make up the lining of the synovial membrane, are believed to play a role in the pathogenesis of RA. RA is a series of inflammation-like responses that induce joint damage and dysfunction and impair patients' life quality. This article first introduced the basic features of RA and analyzes the pathogenesis of RA with SAHS. Then the relationship between RA and SAHS was investigated. Finally, the progress in the treatment for RA with SAHS was reviewed emphatically.
文摘A case of obstructive sleep apnea hypopnea syndrome(OSAHS)in the Department of Otolaryngology of the Third Affiliated Hospital of Inner Mongolia Medical School was collected.The incidence of this disease is high,which seriously threatens the physical and mental health of children,but it has not been paid enough attention by medical workers and parents.We hope we can make early discovery and treatment,relieve upper airway obstruction factors,prevent and treat complications for children with OSAHS through the case analysis,so as to improve their quality of life.
文摘Background:This study aimed to compare the therapeutic effects of different drugs on obstructive sleep apnea/hypopnea syndrome (OSAHS) in children by using a network meta-analysis approach.Methods:PubMed,Embase and Cochrane Library were searched from the inception of each database to November 2015.Randomized controlled trials (RCTs) concerning the comparisons in the therapeutic effects of eight placebo-controlled drugs on OSAHS in children were included in this study.Network meta-analysis combined direct evidence and indirect evidence to evaluate the weighted mean difference (WMD) and surface under the cumulative ranking curves (SUCRA) of therapeutic effects of eight drugs on OSAHS in children.Results:A total of seven RCTs were finally incorporated into our network meta-analysis.Pairwise meta-analysis results revealed that therapeutic effect of placebo was significantly poorer than that of intranasal mometasone furoate,montelukast,budesonide and fiuticasone concerning apnea hypopnea index (AHI) value [WMD=1.40,95% confidence interval (CI)=1.17-1.63;WMD=2.80,95% CI=1.01-4.59;WMD=3.50,95% CI=3.34-3.66;WMD=7.20,95% CI=5.26-9.14,respectively],and fluticasone is better than placebo concerning sleep efficiency (WMD=3.50,95% CI=2.42-4.58);regarding visual analogue scale,the therapeutic effect of placebo was poorer compared with sucralfate and clindamycin (WMD=1.94,95% CI=1.13-2.75;WMD=I.06,95%CI=0.22-1.90),and sucralfate is better than clindamycin (WMD=-0.88,95% CI=-1.65 to-0.11).However,network meta-analysis results showed no obvious difference in the therapeutic effects of different drugs on OSAHS regarding AHI and sleep efficiency.Furthermore,the best SUCRA value was very high for fluticasone concerning AHI (86.6%) and budesonide concerning sleep efficiency (94.0%) for OSAHS treatment.Conclusion:Fluticasone and budesonide have relatively good effects in the treatment of OSAHS in children,thus providing an important guiding significance for the treatment of OSAHS in children.
