Abstract
Omalizumab is a monoclonal antibody indicated for the treatment of severe uncontrolled asthma with an allergic phenotype. Its effectiveness could be influenced by clinical variables and single nucleotide polymorphisms (SNPs) in one or more of the genes involved in the mechanism of action and process of response to omalizumab, and these could be used as predictive biomarkers of response. We conducted an observational retrospective cohort study that included patients with severe uncontrolled allergic asthma treated with omalizumab in a tertiary hospital. Satisfactory response after 12 months of treatment was defined as (1) Reduction ≥ 50% of exacerbations or no exacerbations, (2) Improvement of lung function ≥ 10% FEV1, and (3) Reduction ≥ 50% of OCS courses or no OCS. Polymorphisms in the FCER1A (rs2251746, rs2427837), FCER1B (rs1441586, rs573790, rs1054485, rs569108), C3 (rs2230199), FCGR2A (rs1801274), FCGR2B (rs3219018, rs1050501), FCGR3A (rs10127939, rs396991), IL1RL1 (rs1420101, rs17026974, rs1921622), and GATA2 (rs4857855) genes were analyzed by real-time polymerase chain reaction (PCR) using TaqMan probes. A total of 110 patients under treatment with omalizumab were recruited. After 12 months of treatment, the variables associated with a reduction in exacerbations were the absence of polyposis (odds ratio [OR] = 4.22; 95% confidence interval [CI] = 0.95-19.63), IL1RL1 rs17026974-AG (OR = 19.07; 95% CI = 1.27-547), and IL1RL1 rs17026974-GG (OR = 16.76; 95% CI = 1.22-438.76). Reduction in oral corticosteroids (OCS) was associated with age of starting omalizumab treatment (OR = 0.95; 95% CI = 0.91-0.99) and blood eosinophil levels > 300 cells/µL (OR = 2.93; 95% CI = 1.01-9.29). Improved lung function showed a relationship to the absence of chronic obstructive pulmonary disease (COPD) (OR = 12.16; 95% CI = 2.45-79.49), FCGR2B rs3219018-C (OR = 8.6; 95% CI = 1.12-117.15), GATA2 rs4857855-T (OR = 15.98; 95% CI = 1.52-519.57) and FCGR2A rs1801274-G (OR = 13.75; 95% CI = 2.14-142.68; AG vs. AA and OR = 7.46; 95% CI = 0.94-89.12; GG vs. AA). Meeting one response criterion was related to FCER1A rs2251746-TT (OR = 24; 95% CI = 0.77-804.57), meeting two to age of asthma diagnosis (OR = 0.93; 95% CI = 0.88-0.99), and meeting all three to body mass index (BMI) < 25 (OR = 14.23; 95% CI = 3.31-100.77) and C3 rs2230199-C (OR = 3; 95% CI = 1.01-9.92). The results of this study show the possible influence of the polymorphisms studied on the response to omalizumab and the clinical benefit that could be obtained by defining predictive biomarkers of treatment response.

Abstract
Asthma is a chronic non-communicable disease that affects all age groups. The main challenge this condition poses is its heterogeneity. The role of vitamin D in asthma has aroused great interest, correlating low vitamin D levels and polymorphisms in the genes involved in its metabolic pathway with the risk of asthma. The aim of this study was to evaluate the influence of 13 single nucleotide polymorphisms (SNPs) related to the vitamin D metabolism on the susceptibility to asthma. An observational case-control study was performed, including 221 patients with asthma and 442 controls of Caucasian origin from southern Spain. The SNPs CYP24A1 (rs6068816, rs4809957), CYP27B1 (rs10877012, rs4646536, rs703842, rs3782130), GC (rs7041), CYP2R1 (rs10741657) and VDR (ApaI, BsmI, FokI, Cdx2, TaqI) were analyzed by real-time PCR, using TaqMan probes. The logistic regression model adjusted for body mass index revealed that in the genotype model, carriers of the Cdx2 rs11568820-AA genotype were associated with a higher risk of developing asthma (p = 0.005; OR = 2.73; 95% CI = 1.36-5.67; AA vs. GG). This association was maintained in the recessive model (p = 0.004). The haplotype analysis revealed an association between the ACTATGG haplotype and higher risk of asthma for the rs1544410, rs7975232, rs731236, rs4646536, rs703842, rs3782130 and rs10877012 genetic polymorphisms (p = 0.039). The other SNPs showed no effect on risk of developing asthma. The Cdx2 polymorphism was significantly associated with the susceptibility of asthma and could substantially act as a predictive biomarker of the disease.

Abstract
Severe Uncontrolled Asthma (SUA) counts for more than 25% of cases of severe asthma. The main factors that impair the quality of life of these patients are high doses of oral corticosteroids, the presence of exacerbations, and reduced lung function. The objective of this study was to evaluate, in real life, the clinical improvement of patients with SUA treated with anti-interleukin 5 (IL5) therapies: mepolizumab and benralizumab, together with the search for biomarkers associated with the response. We conducted a retrospective observational cohort study that included patients with severe uncontrolled eosinophilic asthma in a tertiary hospital receiving biological therapies. Three types of response were evaluated: improvement in lung function, reduction in exacerbations, and decrease in the use of oral corticosteroids. After 12 months of treatment, significant reductions were found in the number of exacerbations, the use of oral corticosteroids, and blood eosinophil levels for both biological therapies (p < 0.001). Lung function improved, achieving a significant improvement in %FEV1 (p < 0.001), as well as asthma control, with a significant increase in asthma control test (ACT) scores in both therapies. The markers associated with the corticosteroid-saving effect were the low doses of oral corticosteroids and absence of exacerbations for mepolizumab, and higher blood eosinophilia, absence of chronic obstructive pulmonary disease (COPD), and reduction in oral corticosteroid cycles for benralizumab. The greatest improvement in lung function in both therapies was linked to lower previous FEV1 levels and absence of other respiratory diseases. The reduction in exacerbations was associated with absence of exacerbations the previous year for mepolizumab and never smokers for benralizumab. The results of this real-life study confirm the clinical benefit obtained after the introduction of an anti-IL5 biological therapy and the possible predictive biomarkers of response to treatment.

Abstract
Respiratory function deficits are common sequelae for COVID-19. In this study, we aimed to identify the medical conditions that may influence lung function impairment at 12 months after SARS-CoV2 infection and to analyze the role of alpha-1 antytripsin (AAT) deficiciency (AATD). A cohort study was conducted on hospitalized COVID-19 pneumonia patients in Granada (Spain) during the first infection wave who were referred to a post-COVID-19 hospital clinic. The patients were monitored with three follow-up visits from May 2020 to May 2021. Previous medical history, hospital admission data, baseline parameters and physical examination data were collected at the first visit. Pulmonary function tests were performed at 6 and 12 months together with the determination of AAT level and AATD genotype. After 12 months, 49 out of 157 patients (31.2%) continued to have lung function impairment. A multivariate analysis showed a statistically significant association of lung function impairment with: higher Charlson index; pneumonia with a central and/or mixed distribution; anemia on admission; time in intensive care; need for corticosteroid boluses; abnormal respiratory sounds at 6 months; elevated lactate dehydrogenase at 12 months; abnormal AAT; and MZ genotype. Our results suggest that these medical conditions predispose COVID-19 patients to develop long-term lung function sequelae.

Abstract
INTRODUCTION COVID-19, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to grow all over the world since december of 2019. Although the main clinical manifestation is pulmonary disease, neurological manifestations are a prominent and increasingly recognized feature of the disease. The Acute Disseminated Encephalomyelitis (ADEM) is a rare autoimmune disorder, most commonly triggered by a viral infection. There are a few case reports of ADEM associated with COVID-19, almost all of them associated pulmonary disease. We report the case of a young patient with diagnosis of ADEM with SARS-CoV-2 infection without clinical respiratory symptoms. CASE REPORT A 20-year-old woman with no relevant medical history was brought to the emergency department with a progressive confusional state lasted for 7 days. Family reported the development of smell and taste deficit since two weeks before the onset of neurological symptoms. There were no complaints of pulmonary symptoms. At admission, she was drowsy and disoriented. Left homonymous hemianopsia and an ipsilateral Babinski sign was identified. A brain magnetic resonance image was done showing multiple hyperintense bilateral, asymmetric patchy and poorly marginated lesions with gadolinium enhancement. She was SARS-CoV-2 PCR positive on nasopharyngeal swab. Intravenous high-dose glucocorticoids were administered with marked clinical improvement. CONCLUSION ADEM is an extremely uncommon complication of SARS-CoV-2infection. Acute disseminated encephalomyelitis should be considered a potentially treatable cause of encephalopathy or multifocal neurological deficits in COVID-19 patients, even in the absence of respiratory symptoms.

Abstract
BACKGROUND Omalizumab is a fully humanized monoclonal antibody indicated as add-on therapy to improve asthma control in patients with severe persistent allergic asthma. AIMS The aim of this study was to evaluate social, healthcare expenditure and clinical outcomes changes after incorporating omalizumab into standard treatment in the control of severe asthma. METHODS In this multicentre retrospective study, a total of 220 patients were included from 15 respiratory medicine departments in the regions of Andalusia and Extremadura (Spain). Effectiveness was calculated as a 3-point increase in the Asthma Control Test (ACT) and a reduction in the annual number of exacerbations. The economic evaluation included both direct and indirect costs. Incremental cost-effectiveness ratio (ICER) was calculated. Results from the year before and the year after incorporation of omalizumab were compared. RESULTS After adding omalizumab, improvement of lung function, asthma and rhinitis according to patient perception, as well as the number of exacerbations and asthma control measured by the ACT score were observed. Globally, both healthcare resources and pharmacological costs decreased after omalizumab treatment, excluding omalizumab cost. When only direct costs were considered, the ICER was €1712 (95% CI 1487-1995) per avoided exacerbation and €3859 (95% CI 3327-4418) for every 3-point increase in the ACT score. When both direct and indirect costs were considered, the ICER was €1607 (95% CI 1385-1885) for every avoided exacerbation and €3555 (95% CI 3012-4125) for every 3-point increase. CONCLUSIONS Omalizumab was shown to be an effective add-on therapy for patients with persistent severe asthma and allowed reducing key drivers of asthma-related costs.

Abstract
SETTING South Granada Health Area (SGHA), Spain. OBJECTIVE To describe the characteristics of concomitant tuberculosis (TB) and lung cancer cases. DESIGN A total of 319 TB cases diagnosed between January 2003 and December 2010 were evaluated and identified using a prospective database. During this period, samples of bronchial secretions were obtained from all patients who underwent fibreoptic bronchoscopy (FBS) as part of a TB screening programme. A descriptive study was conducted. RESULTS Concomitant TB and lung cancer were diagnosed in 15 cases (4.7% of total TB cases). The most common radiographic finding was atelectasis (53.3%), and the most common histological type was epidermoid carcinoma (60%). Lung cancer stage was advanced (III-IV) in 60% of the cases. CONCLUSION The association between TB and lung cancer found in the SGHA after implementing a TB screening programme was higher than in other studies. This suggests that it would be advisable to perform acid-fast bacilli smear and mycobacterial culture of bronchial aspirates in all patients with presumed lung cancer, particularly in high TB prevalence areas.

Abstract
BACKGROUND Under-reporting of tuberculosis (TB) cases complicates disease control, hinders contact tracing and alters the accuracy of epidemiological data, including disease burden. The objective of the present study is to evaluate the proportion of unreported TB cases in Spanish healthcare facilities and to identify the associated factors. METHODS A multi-center retrospective study design was employed. The study included TB cases diagnosed in 16 facilities during 2011-2012. These cases were compared to those reported to the corresponding public health departments. Demographic, microbiological and clinical data were analyzed to determine the factors associated with unreported cases. Associated factors were analyzed on a bivariate level using the x(2) test and on a multivariate level using a logistic regression. Odds ratios (OR) and 95 % confidence intervals (CI) were calculated. RESULTS Of the 592 TB cases included in the study, 85 (14.4 %) were not reported. The percentage of unreported cases per healthcare center ranged from 0-45.2 %. The following variables were associated to under-reporting at a multivariate level: smear-negative TB (OR = 1.87; CI:1.07-3.28), extrapulmonary disease (OR = 2.07; CI:1.05-4.09) and retired patients (OR = 3.04; CI:1.29-7.18). A nurse case manager was present in all of the centers with 100 % reporting. The percentage of reported cases among the smear-positive cases was 9.4 % and 19.4 % (p = 0.001) among the rest of the study population. Smear-positive TB was no associated to under-reporting. CONCLUSIONS It is important that TB Control Programs encourage thorough case reporting to improve disease control, contact tracing and accuracy of epidemiological data. The help from a TB nurse case manager could improve the rate of under-reporting.

Abstract
OBJECTIVE To compare the effectiveness of sedation, the time required for weaning, and the costs of prolonged sedation of critically ill mechanically ventilated patients with midazolam and propofol. DESIGN Open-label, randomized, prospective, phase IV clinical trial. SETTING Medical and surgical intensive care unit (ICU) in a community hospital. PATIENTS All ICU admissions (medical, surgical and trauma) requiring mechanical ventilation for > 24 hrs. A total of 108 patients were included in the study. INTERVENTIONS Patients were randomized to receive midazolam or propofol. The dose range allowed for each drug was 0.1 to 0.5 mg/kg/hr for midazolam and 1 to 6 mg/kg/hr for propofol. The lowest dose that achieved an adequate patient-ventilator synchrony was infused. All patients received 0.5 mg/kg/24 hrs of morphine chloride. MEASUREMENTS AND MAIN RESULTS The level of sedation was quantified by the Ramsay scale every 2 hrs until weaning from mechanical ventilation was started. If sedation could not be achieved by infusing the highest dose of midazolam or propofol, the case was recorded as a therapeutic failure. In the propofol group, serum triglycerides were determined every 72 hrs. Concentrations of > 500 mg/dL were also recorded as a therapeutic failure. When the patient was ready for weaning according to defined criteria, sedation was interrupted abruptly and the time from interruption of sedation to the first T-bridge trial and to extubation was measured. Cost analysis was performed based on the cost of intensive care in our unit ($54/hr). In the midazolam group (n = 54), 15 (27.8%) patients died; 11 (20.4%) patients had therapeutic failure; and 28 (51.8%) patients were subjected to a T-bridge trial. In the propofol group (n = 54), these proportions were 11 (20.4%), 18 (33.4% [including seven due to inadequate sedation, and 11 due to hypertriglyceridemia]), and 25 (46.2%), respectively. None of these values was significantly different between the two groups. Duration of sedation was 141.7 +/- 89.4 (SD) hrs and 139.7 +/- 84.7 hrs (p = NS), and cost (US dollars) attributed to sedation was $378 +/- 342 and $1,047 +/- 794 (p = .0001) for the midazolam and propofol groups, respectively. In the midazolam group, time from discontinuation of the drug infusion to extubation was 97.9 +/- 54.6 hrs (48.9 +/- 47.2 hrs to the first disconnection, and 49.0 +/- 23.7 hrs to extubation). In the propofol group, time from discontinuation of the drug infusion to extubation was 34.8 +/- 29.4 hrs (4.0 +/- 3.9 hrs to the first disconnection, and 30.8 +/- 29.2 hrs to extubation). The difference between the two groups in the weaning time was 63.1 +/- 12.5 (SEM) hrs (p < .0001). Cost per patient in the midazolam group (including ICU therapy and sedation with midazolam) was $10,828 +/- 5,734. Cost per patient in the propofol group was $9,466 +/- 5,820, $1,362 less than in the midazolam group. CONCLUSIONS In our population of critically ill patients sedated with midazolam or propofol over prolonged periods, midazolam and propofol were equally effective as sedative agents. However, despite remarkable differences in the cost of sedation with these two agents, the economic profile is more favorable for propofol than for midazolam due to a shorter weaning time associated with propofol administration.
