Tracheostomy in patients with COVID-19: predictors and clinical features.

BACKGROUND: Around 20% of patients hospitalized for COVID-19 need mechanical ventilation (MV). MV may be prolonged, thus warranting tracheostomy. METHODS: Observational cohort study enrolling patients admitted due to COVID-19. Demographic and clinical data at hospital and ICU admission were collected. The primary endpoint was to identify parameters associated with a need for tracheostomy; secondary endpoints were to analyze the clinical course of patients who needed tracheostomy. RESULTS: 118 patients were enrolled; 37 patients (31.5%) were transferred to ICU, of which 11 (29.72%) needed a tracheostomy due to prolonged MV. Sequential Organ Failure Assessment (SOFA) score at ICU admission (OR 0.65, 95% CI 0.47-0.92, p 0.015) was the only variable found to be associated with increased risk of the need for tracheostomy, with a cut-off point of 4.5 (sensitivity 0.72, specificity 0.73, positive predictive value 0.57 and negative predictive value 0.85). The main complications were nosocomial infection (100%), supraventricular cardiac arrhythmia (45.5%), agitation (54.5%), pulmonary thromboembolism (9.1%) and depression (9.1%). All patients presented with hypoalbuminemia and significant critical illness polyneuropathy. CONCLUSION: SOFA at ICU admission is associated with an increased risk of tracheostomy in patients with COVID-19. Moreover, they present clinical features similar to those with chronic critical illness and suffer SARS-CoV-2-related complications.

C-Reactive Protein Concentration in Steady-State Bronchiectasis: Prognostic Value of Future Severe Exacerbations. Data From the Spanish Registry of Bronchiectasis (RIBRON) / Concentración de la proteína C reactiva en las bronquiectasias en fase estable: valor pronóstico de futuras exacerbaciones graves. Datos del registro español de pacientes con bronquiectasias (RIBRON)

BACKGROUND: Both systemic inflammation and exacerbations have been associated with greater severity of bronchiectasis. Our objective was to analyze the prognostic value of the peripheral concentration of C-reactive protein (CRP) for the number and severity of exacerbations in patients with bronchiectasis. METHODS: Patients from the Spanish Bronchiectasis Registry (RIBRON) with valid data on their CRP value (in a clinically stable phase) and valid data on exacerbations during the first year of follow-up were included. A logistic regression analysis was used to evaluate the prognostic value of the CRP concentration (divided into tertiles) with the presence of at least one severe exacerbation or at least two mild-moderate exacerbations during the first year of follow-up. RESULTS: 802 patients (mean age: 68.1 [11.1 years], 65% female) were included. Of these, 33.8% and 13%, respectively, presented ≥ 2 mild-moderate exacerbations or at least one severe exacerbation during the first year of follow-up. The mean value of the CRP was 6.5 (17.6 mg/L). Patients with a CRP value between 0.4 and 2.7 mg/L (second tertile) and ≥ 2.7 mg/L (third tertile) presented a 2.9 (95%CI: 1.4-5.9) and 4.2 (95% CI: 2.2-8.2) times greater probability, respectively, of experiencing a severe exacerbation than those with < 0.4 mg/L (control group), regardless of bronchiectasis severity or a history of previous exacerbations. However, the CRP value did not present any prognostic value for the number of mild-moderate exacerbations. CONCLUSIONS: The CRP value was associated with a greater risk of future severe exacerbations but not with mild or moderate exacerbations in patients with steady-state bronchiectasis

CONTEXTO GENERAL: Tanto la inflamación sistémica como las exacerbaciones se han asociado con una mayor gravedad de las bronquiectasias. Nuestro objetivo fue analizar el valor de la concentración en sangre periférica de proteína C reactiva (PCR) para predecir el número y la gravedad de las exacerbaciones en pacientes con bronquiectasias. MÉTODOS: Se incluyeron pacientes del Registro Español de Pacientes con Bronquiectasias (RIBRON) con datos válidos sobre sus niveles de PCR (en fase clínicamente estable) y datos válidos sobre exacerbaciones durante el primer año de seguimiento. Se utilizó un análisis de regresión logística para evaluar el valor pronóstico de la concentración de PCR (dividida en terciles) con la presencia de al menos una exacerbación grave o al menos dos exacerbaciones leves-moderadas durante el primer año de seguimiento. RESULTADOS: Se incluyeron 802 pacientes (edad media: 68,1 [11,1] años, 65% mujeres). De ellos, el 33,8% y el 13%, respectivamente, presentaron ≥ 2 exacerbaciones leves-moderadas o al menos una exacerbación grave durante el primer año de seguimiento. El valor medio de la PCR fue de 6,5 (17,6) mg/L. Los pacientes con un valor de PCR entre 0,4 y 2,7 mg/L (segundo tercil) y ≥ 2,7 mg/L (tercer tercil) presentaron 2,9 veces (IC 95%: 1,4-5,9) y 4,2 veces (IC 95%: 2,2-8,2) más probabilidad, respectivamente, de experimentar una exacerbación grave que aquellos con < 0,4 mg/L (grupo de control), independientemente de la gravedad de las bronquiectasias o de presentar antecedentes de exacerbaciones previas. Sin embargo, el valor de la PCR no presentó ninguna utilidad pronóstica para el número de exacerbaciones leves-moderadas. CONCLUSIONES: El valor de la PCR se asoció a un mayor riesgo de exacerbaciones graves en el futuro, pero no a las exacerbaciones leves o moderadas en pacientes con bronquiectasias en fase estable

Long-term Effect of CPAP Treatment on Cardiovascular Events in Patients With Resistant Hypertension and Sleep Apnea. Data From the HIPARCO-2 Study.

BACKGROUND: There is some controversy about the effect of continuous positive airway pressure (CPAP) on the incidence of cardiovascular events (CVE). However, the incidence of CVE among patients with both obstructive sleep apnea (OSA) ans resistant hypertension (HR) has not been evaluated. Our objective was to analyze the long-term effect of CPAP treatment in patients with RH and OSA on the incidence of CVE. METHODS: Multi-center, observational and prospective study of patients with moderate-severe OSA and RH. All the patients were followed up every 3-6 months and the CVE incidence was measured. Patients adherent to CPAP (at least 4h/day) were compared with those with not adherent or those who had not been prescribed CPAP. RESULTS: Valid data were obtained from 163 patients with 64 CVE incidents. Treatment with CPAP was offered to 82%. After 58 months of follow-up, 58.3% of patients were adherent to CPAP. Patients not adherent to CPAP presented a non-significant increase in the total CVE incidence (HR:1.6; 95%CI: 0.96-2.7; p=0.07). A sensitivity analysis showed that patients not adherent to CPAP had a significant increase in the incidence of cerebrovascular events (HR: 3.1; CI95%: 1.07-15.1; p=0.041) and hypertensive crises (HR: 5.1; CI95%: 2.2-11.6; p=0.006), but the trend went in the opposite direction with respect to coronary events (HR: 0.22; CI95%: 0.05-1.02; p=0.053). CONCLUSIONS: In patients with RH and moderate-severe OSA, an uneffective treatment with CPAP showed a trend toward an increase in the incidence of CVE (particularly neurovascular events and hypertensive crises) without any changes with respect to coronary events.

The HIPARCO-2 study: long-term effect of continuous positive airway pressure on blood pressure in patients with resistant hypertension: a multicenter prospective study.

INTRODUCTION: Short-term treatment with continuous positive airway pressure (CPAP) produces a clinically significant reduction in blood pressure (BP) in patients with obstructive sleep apnea (OSA) and resistant hypertension. However, it is unknown whether this effect continues over the long-term. Our objective was to assess the effect of long-term CPAP on BP in patients with OSA and resistant hypertension. METHODS: The study included 161 patients diagnosed with both OSA [apnea--hypopnea index (AHI) ≥15] and resistant hypertension diagnosed via 24-hour ambulatory BP measurement (24-h ABPM), in whom a second analysis via 24-h ABPM was performed at the end of the follow-up. RESULTS: Patients were followed up within 59 months [interquartile range (IQR): 44-70]. CPAP treatment was prescribed to 82% of the patients (70% with good adherence to CPAP defined as use of CPAP at least 4 h/night). A comparison between the adherent group and nonadherent group (including those with CPAP not prescribed) showed that CPAP adherents had a significant drop in the 24-h BP, both systolic [-3.9 mmHg; 95% confidence interval (CI): -8.1 to 0.3] and diastolic pressure (-3.5 mmHg [95% [CI]: -6.4-0.5]), with a higher magnitude during the night (-5.5 and -4.9 mmHg, respectively). The CPAP adherent group needed a mean of 1.1 less antihypertensive drugs (particularly spironolactone). Finally, there was a positive correlation between the drop in 24-h SBP and the hours of CPAP use (r = 0.24; P = 0.01). CONCLUSION: Good adherence to long-term CPAP treatment largely succeeded in significantly reducing BP in those patients with OSA and resistant hypertension, despite the use of a lower number of antihypertensive drugs.

Obstructive Sleep Apnea and Arterial Hypertension: Implications of Treatment Adherence.

PURPOSE OF REVIEW: This review seeks to present an overview of the recent literature on the importance of CPAP and antihypertensive treatment adherence in blood pressure control of hypertensive patients, especially those with obstructive sleep apnea. RECENT FINDINGS: Although it is unquestionable that a good adherence to CPAP and antihypertensive drugs is crucial to improvements in sleep-related symptoms, blood pressure levels (even the modest reductions of 2-2.5 mmHg achieved by CPAP treatment) and future cardiovascular risk, this adherence decreases over time, despite efforts made toward behavioral intervention and monitoring. Curiously, although taking a drug would seem to be easier than the use of CPAP treatment, based on current information, it seems that the compliance with drug treatment in hypertensive subjects is not better than that achieved with CPAP treatment in OSA patients with hypertension. However, some studies have shown some phenotypes of hypertensive and OSA patients with good adherence and better hypertensive effect, such as those with uncontrolled blood pressure (resistant and refractory hypertension), severe forms of sleep apnea, and more sleep-related symptoms, especially a higher degree of diurnal hypersomnia. The positive effect of antihypertensive drugs and CPAP treatment on blood pressure levels depends on the degree of treatment adherence, especially in forms of uncontrolled hypertension, but this adherence decreases over time. Educational programs and new devices are needed to improve adherence to treatment in these patients, along with fuller understanding of the different patterns and phenotypes of non-adherence.

Treatment with CPAP in Elderly Patients with Obstructive Sleep Apnoea.

The population pyramid is changing as a result of the ever-increasing life expectancy, which makes it crucial to acquire an in-depth understanding of the diseases that most often affect the elderly. Obstructive sleep apnoea (OSA) affects 15%-20% of the population aged over 65 years. Despite this prevalence, there have been very few specific studies on the management of OSA in this age group, even though over 60% of the patients aged over 65-70 years who attend sleep units with suspicion of OSA receive treatment with continuous positive airway pressure (CPAP), on the basis of an extrapolation of the positive results achieved by CPAP in clinical trials involving middle-aged males. However, the latter's form of presentation, evolution and, probably, prognosis comparing with OSA are not the same as those of elderly patients. Recent clinical trials performed on an exclusive series of elderly patients have shed light on the possible role of CPAP treatment in elderly patients with OSA, but there are still many questions that need to be answered. The physiological increase in the number of sleep-related disorders with the passing of years, and the lack of validated diagnostic and therapeutic tools for this age group are probably the greatest obstacles to define, diagnose and treat OSA in the elderly.

Resistant/Refractory Hypertension and Sleep Apnoea: Current Knowledge and Future Challenges.

Hypertension is one of the most frequent cardiovascular risk factors. The population of hypertensive patients includes some phenotypes whose blood pressure levels are particularly difficult to control, thus putting them at greater cardiovascular risk. This is especially true of so-called resistant hypertension (RH) and refractory hypertension (RfH). Recent findings suggest that the former may be due to an alteration in the renin-angiotensin-aldosterone axis, while the latter seems to be more closely related to sympathetic hyper-activation. Both these pathophysiological mechanisms are also activated in patients with obstructive sleep apnoea (OSA). It is not surprising, therefore, that the prevalence of OSA in RH and RfH patients is very high (as reflected in several studies) and that treatment with continuous positive airway pressure (CPAP) manages to reduce blood pressure levels in a clinically significant way in both these groups of hypertensive patients. It is therefore necessary to incorporate into the multidimensional treatment of patients with RH and RfH (changes in lifestyle, control of obesity and drug treatment) a study of the possible existence of OSA, as this is a potentially treatable disease. There are many questions that remain to be answered, especially regarding the ideal combination of treatment in patients with RH/RfH and OSA (drugs, renal denervation, CPAP treatment) and patients' varying response to CPAP treatment.

Initial Inflammatory Profile in Community-acquired Pneumonia Depends on Time since Onset of Symptoms.

RATIONALE: Assessment of the inflammatory response can help the decision-making process when diagnosing community-acquired pneumonia (CAP), but there is a lack of information about the influence of time since onset of symptoms. OBJECTIVES: We studied the impact of the number of days since onset of symptoms on inflammatory cytokines and biomarker concentrations at CAP diagnosis in hospitalized patients. METHODS: We performed a secondary analysis in two prospective cohorts including 541 patients in the derivation cohort and 422 in the validation cohort. The time since onset of symptoms was self-reported, and patients were classified as early presenters (<3 d) and nonearly presenters. Biomarkers (C-reactive protein [CRP] and procalcitonin [PCT] in both cohorts) and cytokines in the derivation cohort (IL-1, - 6, -8, -10, and tumor necrosis factor-α) were measured within 24 hours of hospital admission. MEASUREMENTS AND MAIN RESULTS: In early presenters, CRP was significantly lower, whereas PCT, IL-6, and IL-8 were higher. Nonearly presenters showed significantly lower PCT, IL-6, and IL-8 levels. In the validation cohort, CRP and PCT exhibited identical patterns: CRP levels were 36.4% greater in patients with 3 or more days since onset of symptoms than in those with less than 3 days since symptom onset in the derivation cohort and 38.2% in the validation cohort. PCT levels were 40% lower in patients with 3 or more days since onset of symptoms in the derivation cohort and 56% in the validation cohort. CONCLUSIONS: Time since symptom onset modifies the systemic inflammatory profile at CAP diagnosis. This information has relevant clinical implications for management, and it should be taken into account in the design of future clinical trials.

Factors associated with hospitalization in bronchiectasis exacerbations: a one-year follow-up study.

BACKGROUND: Bronchiectasis (BE) is a chronic structural lung disease with frequent exacerbations, some of which require hospital admission though no clear associated factors have been identified. We aimed to evaluate factors associated with hospitalization due to exacerbations during a 1-year follow-up period. METHODS: A prospective observational study was performed in patients recruited from specialized BE clinics. We considered all exacerbations diagnosed and treated with antibiotics during a follow-up period of 1 year. The protocol recorded baseline variables, usual treatments, Bronchiectasis Severity Index (BSI) and FACED scores, comorbid conditions and prior hospitalizations. RESULTS: Two hundred and 65 patients were recruited, of whom 162 required hospital admission during the follow-up period. Independent risk factors for hospital admission were age, previous hospitalization due to BE, use of proton pump inhibitors, heart failure, FACED and BSI, whereas pneumococcal vaccination was a protective factor. The area under the receiver operator characteristic curve (AUC) was 0.799 for BSI model was 0.799, and 0.813 for FACED model. CONCLUSIONS: Previous hospitalization, use of proton pump inhibitors, heart failure along with BSI or FACED scores is associated factors for developing exacerbations that require hospitalization. Pneumococcal vaccination was protective. This information may be useful for the design of preventive strategies and more intensive follow-up plans.
