Assessment of cephalometric parameters and correlation with the severity of the obstructive sleep apnea syndrome.

BACKGROUND: In individuals diagnosed with obstructive sleep apnea syndrome (OSAS), variations in craniofacial structure have been inconsistently documented, showing differing degrees of alteration between obese and nonobese patients. In addition, sleep disturbance has also been shown to induce disequilibrium in this population of patients. This pilot observational study aimed to assess craniofacial values in obese and nonobese subpopulations of patients with OSAS and their correlation and association with the severity of OSAS. We also assessed whether OSAS patients are characterized by an impaired equilibrium in relation to and associated with the severity of OSAS. METHODS: We included all consecutive adult patients with OSAS. Through cephalometry, we assessed the upper (UPa-UPp) and lower (LPa-LPp) pharynx diameters, superior anterior facial height (Sor-ANS), anterior facial height (ANS-Me), anterior vertical dimension (Sor-Me), posterior facial height (S-Go) and craniovertebral angle (CVA). Furthermore, we analyzed postural equilibrium through a stabilometric examination. RESULTS: Forty consecutive OSAS patients (45% female with a mean age of 56 ± 8.2 years) were included. The subgroup of nonobese patients had a reduced UPa-UPp (p = 0.02). Cephalometric measurements were correlated with the severity of OSAS in nonobese patients, whereas only Sor-ANS was correlated with the severity of OSAS in the obese subpopulation. In the overall population, altered craniofacial values are associated with severe OSAS. Although there are differences in equilibrium between obese and nonobese OSAS patients, the stabilometric measurements were not correlated or associated with OSAS severity. CONCLUSION: Altered craniofacial values and compromised equilibrium in OSAS patients are linked to OSAS severity. Therefore, the management of OSAS should be tailored not only to weight management but also to craniofacial and postural rehabilitation to enhance patient outcomes.

Effects of continuous positive airway pressure on comprehensive geriatric assessment and cognitive function in elderly patients with obstructive sleep apnea syndrome.

Obstructive sleep apnea syndrome (OSAS) can lead to cognitive impairment and depression affecting memory, attention, and executive functions. Continuous positive airway pressure (CPAP) treatment seems to be able to revert changes in brain networks and neuropsychological tests correlated to OSAS. The aim of the present study was to evaluate the effects of a 6-month treatment with CPAP on functional, humoral and cognitive parameters in a cohort of elderly OSAS patients with several comorbidities. We enrolled 360 elderly patients suffering from moderate to severe OSAS and indication for nocturnal CPAP. At baseline the Comprehensive Geriatric Assessment (CGA) revealed a borderline Mini-Mental State Examination (MMSE) score that improved after 6-month treatment with CPAP (25.3 ± 1.6 vs 26 ± 1.5; p < 0.0001), as well as the Montreal Cognitive Assessment (MoCA) showed a mild improvement (24.4 ± 2.3 vs 26.2 ± 1.7; p < 0.0001). Moreover, functionality activities increased after treatment, as documented by a short physical performance battery (SPPB) (6.3 ± 1.5 vs 6.9 ± 1.4; p < 0.0001). Reduction of the Geriatric Depression Scale (GDS) from 6.0 ± 2.5 to 4.6 ± 2.2 (p < 0.0001) was also detected. Changes of homeostasis model assessment (HOMA) index, oxygen desaturation index (ODI), sleep-time spent with saturation below 90% (TC90), peripheral arterial oxyhaemoglobin saturation (SpO2), apnea-hypopnea index (AHI) and estimation of glomerular filtration rate (eGFR), contributed, respectively, to 27.9%, 9.0%, 2.8%, 2.3%, 1.7% and 0.9% of MMSE variability for a total of 44.6% of MMSE variations. GDS score changes were due to the improvement of AHI, ODI and TC90, respectively, for 19.2%, 4.9%, 4.2% of the GDS variability, cumulative responsible for 28.3% of GDS modifications. The present real-world study shows that CPAP treatment is able to improve cognition and depressive symptoms in OSAS elderly patients.

Short term effect of sacubitril/valsartan on comprehensive geriatric assessment in chronic heart failure: a real life analysis.

Sacubitril/Valsartan (Sac-Val) has improved clinical prognosis in patients affected by heart failure (HF) with reduced ejection fraction (HFrEF). Comorbidities have a crucial impact on clinical presentation and prognosis in HF patients. Cognitive impairment (CoI) and Depression are a very common comorbidity in patients with HF and is widely recognized as a specific determinant of chronic disability, and HF patients with poor physical functional performance in Short physical performance battery (SPPB) showed a worse prognosis. The aim of the present study was to evaluate the potential effects of Sac-Val on functional, humoral, and cognitive aspects, evaluated by performing comprehensive geriatric assessment (CGA), in a cohort of elderly HFrEF. We studied 61 patients (51 men and 10 women, mean age 76.4 ± 5.1 years) suffering from HFrEF. After 6 months follow-up, we observed a significant improvement in humoral and functional parameters of CGA, renal function, NTpro-BNP levels and echocardiographic parameters. In the whole population, multivariate analysis shows that changes of Cardiac Index, NT-proBNP and Respiratory rate contributed for 26.0%, 9.7% and 4.8% to GDS variability, respectively, and the whole model accounted for a 41.1% of GDS variation; moreover changes of Global longitudinal strain, estimated glomerular filtration rate, Cardiac Index and BMI contributed for 23.9%, 11.7%, 5.4% and 4.0% to SPPB variability, respectively, and the whole model accounted for a 45% of SPPB variation. This represents the first real-world study carried out in an elderly population suffering from chronic HFrEF with numerous comorbidities, in which treatment with Sac-Val for 6 months induced important improvements in clinical, humoral, hemodynamic, and functional outcomes, without adverse effects on cognitive performance.

Clinical and economic consequences of switching from omalizumab to mepolizumab in uncontrolled severe eosinophilic asthma.

Severe asthma is burdened by frequent exacerbations and use of oral corticosteroids (OCS), which worsen patients' health and increase healthcare spending. The aim of this study was to assess the clinical and economic impact of switching from omalizumab (OMA) to mepolizumab (MEP) in patients eligible for both biologics, but not optimally controlled by omalizumab. We retrospectively enrolled uncontrolled severe asthmatic patients who switched from OMA to MEP during the last two years. Information included blood eosinophil count, asthma control test (ACT), spirometry, serum IgE, fractional exhaled nitric oxide (FeNO), OCS intake, drugs, exacerbations/hospitalizations, visits and diagnostic exams. Within the perspective of Italian National Health System, a pre- and post-MEP 12-month standardized total cost per patient was calculated. 33 patients were enrolled: five males, mean age 57 years, disease onset 24 years. At OMA discontinuation, 88% were OCS-dependent with annual mean rate of 4.0 clinically significant exacerbations, 0.30 exacerbations needing emergency room visits or hospitalization; absenteeism due to disease was 10.4 days per patient. Switch to MEP improved all clinical outcomes, reducing total exacerbation rate (RR = 0.06, 95% CI 0.03-0.14), OCS-dependent patients (OR = 0.02, 95% CI 0.005-0.08), and number of lost working days (Δ = - 7.9, 95% CI - 11.2 to - 4.6). Pulmonary function improved, serum IgE, FeNO and eosinophils decreased. Mean annual costs were €12,239 for OMA and €12,639 for MEP (Δ = €400, 95% CI - 1588-2389); the increment due to drug therapy (+ €1,581) was almost offset by savings regarding all other cost items (- €1,181). Patients with severe eosinophilic asthma, not controlled by OMA, experienced comprehensive benefits by switching to MEP with only slight increases in economic costs.

Real-life rapidity of benralizumab effects in patients with severe allergic eosinophilic asthma: Assessment of blood eosinophils, symptom control, lung function and oral corticosteroid intake after the first drug dose.

Benralizumab is a humanized monoclonal antibody which binds to the α subunit of the interleukin-5 (IL-5) receptor and to the FcγRIIIa receptor expressed by natural killer cells, thus suppressing the pro-eosinophil actions of IL-5 and triggering eosinophil apoptosis via the very effective mechanism of antibody-dependent cell-mediated cytotoxicity (ADCC). Because of its recent approval and introduction in clinical practice for the add-on biological therapy of severe eosinophilic asthma, real-life investigations are still lacking. In this regard, our present real-life study refers to 13 patients with severe allergic eosinophilic asthma, currently under treatment with benralizumab at the Respiratory Unit of "Magna Græcia" University Hospital located in Catanzaro, Italy. Already 4 weeks after the first subcutaneous injection of benralizumab at the dosage of 30 mg, blood eosinophil count rapidly dropped down from 814.7 ±â€¯292.3 cells/µL to 51.3 ±â€¯97.5 cells/µL (p < 0.0001). This relevant hematologic change was associated with quick and significant increases in asthma control test (ACT) score (from 15.31 ±â€¯2.78 to 21.15 ±â€¯3.58; p < 0.0001), pre-bronchodilator forced expiratory volume in 1 s (FEV1) (from 1441 ±â€¯757.9 mL to 1887 ±â€¯837.3 mL; p < 0.001), and morning peak expiratory flow (PEF) (from 4.21 ±â€¯2.20 to 5.33 ±â€¯1.99 L/sec; p < 0.01). Furthermore, the marked improvement in global health status experienced by our patients allowed them to progressively lower and then completely interrupt, within 4 weeks, their daily intake of oral corticosteroids (OCS), which thereby fell from 15.58 ±â€¯8.30 to 0 mg (p < 0.0001) of prednisone. Therefore, such preliminary results suggest that in patients with severe allergic eosinophilic asthma benralizumab can exert, within a real-life context, a very rapid and effective therapeutic action, already detectable 4 weeks after the first drug administration.
