RESUMEN
INTRODUCTION: Asthma management is strongly dependent on physician and patient beliefs and perceptions about the disease and its long-term treatment. The APPaRENT 3 study was conducted to explore factors influencing treatment choice and to understand patients' and physicians' attitudes and perspectives on the use of controller inhalers in regular versus flexible dosing for asthma management. METHODS: This cross-sectional survey of patients with asthma and treating physicians was conducted in seven countries: Indonesia, Malaysia, Philippines, Thailand, Vietnam (patient survey only), Saudi Arabia, and the United Arab Emirates. Assessment was carried out through an online/face-to-face questionnaire, where patients' viewpoints were focused on their attitudes and beliefs about asthma and treatment adherence, whereas physicians' viewpoints were gathered on their attitudes and beliefs about asthma management, knowledge of and adherence to asthma treatment guidelines, and asthma treatment regimens. RESULTS: Overall, 1400 patients (mean age, 34 years) and 599 physicians (mean age, 43 years) were included in the survey. Physicians similarly prioritised symptom control (39%) and exacerbation reduction (40%) in moderate asthma, whereas patients prioritised symptom control (41%) over exacerbation reduction (22%). Although both groups (physicians, 86%; patients, 84%) perceived asthma as well-controlled, poor management was evident based on Asthma Control Test (ACT) scores (mean, 15.7; standard deviation, 4.14; 82% had an ACT score < 20) and high symptom burden (39% reported nighttime awakenings or early mornings ≥ 2 nights/week). Most patients (76%) with moderate asthma were prescribed regular dosing, with the most common treatment being inhaled corticosteroid (ICS)/long-acting ß2-agonist (LABA) with as-needed inhaled short-acting ß2-agonist (SABA; 20%). Among patients on maintenance and reliever therapy, 93% of patients received a separate inhaled reliever. CONCLUSIONS: Despite high symptom burden, patients overestimated their level of asthma control. Physicians prioritised controlling symptoms and reducing exacerbations as treatment goals for moderate asthma, often prescribing regular dosing with ICS/LABA with as-needed inhaled SABA.
Managing asthma depends a lot on what doctors and patients think about the illness and its long-term treatment. This study looked into what influences treatment decisions and what patients and doctors think about using inhalers regularly or on an as-needed basis to manage asthma across seven countries (Indonesia, Malaysia, Philippines, Thailand, Vietnam [patient survey only], Saudi Arabia, and the United Arab Emirates). In this study, patients with asthma and doctors managing asthma completed an online/face-to-face questionnaire. The study aimed to understand what patients think about asthma and their treatment plan. Meanwhile, the doctors were asked what they think about managing asthma and how much they apply clinical guidelines for treating patients with asthma. Doctors believed it is equally important to control symptoms and prevent worsening of symptoms in patients with moderate asthma, while patients cared more about controlling symptoms than preventing worsening of symptoms. While doctors and patients both regarded asthma as well-controlled, many patients had low Asthma Control Test scores and experienced a lot of symptoms, suggesting that they are poor perceivers of asthma control. Most patients with moderate asthma were given regular treatment, usually with inhaled corticosteroid combined with long-acting ß2-agonist along with as-needed short-acting ß2-agonist as a reliever. Most patients who were prescribed the same inhaler for regular use and as a reliever also had a separate inhaler for quick relief of symptoms. This study shows the need for patients and doctors to have better conversations about asthma, its treatments, and what to expect from them.

Melioidosis is a tropical infectious disease that ranks as northeastern Thailand's third most common infectious cause of death. The manifestations of melioidosis vary depending on the organs involved and often resemble malignancy and tuberculosis. We present a case of an atypical melioidosis presentation in a patient with low-grade fever and facial swelling without any risk factors. Chest CT revealed a 3.3-cm heterogeneous enhancing right lower paratracheal lymph nodes with thrombosis of the superior vena cava and azygos vein. Endobronchial ultrasound-guided transbronchial needle aspiration of lymph node was performed, and Burkholderia pseudomallei was identified through lymph node culture. The patient underwent a three-week intravenous course of ceftazidime and a 12-week oral course of trimethoprim-sulfamethoxazole. Oral anticoagulation was also administered. Follow-up computed tomography of the thorax after completion of treatment revealed no residual lymphadenopathy and thrombosis.
RESUMEN
Background and Objective: Pulmonary sarcoidosis and tuberculosis (TB) are the most frequent tissue-confirmed granulomatous diseases. Due to its unknown etiology, pulmonary sarcoidosis is diagnosed by ruling out other granulomatous diseases and necessitating clinical, radiological, and pathological evidence. There are many factors that contribute to the diagnostic dilemma between these two diseases. Even though some aspects of both diseases, such as their pathological evidence and abnormal X-ray findings, are quite similar, the treatment options for each are entirely different. The standard treatment for sarcoidosis is immunosuppressive agents such as glucocorticoids, which can exacerbate TB. Consequently, the overlap between clinical and radiological features constitutes a significant challenge for many physicians in selecting the optimal treatment for each patient. Therefore, the exclusion of pulmonary TB is a mandatory step for the diagnosis of pulmonary sarcoidosis. This article reviews and summarizes basic science and clinical research on distinguishing these two disorders. Methods: A systematic search of the MEDLINE and PubMed databases focusing on studies published within the last 35 years was conducted. The last search date is February 4, 2023. The authors used the following combinations of terms: tuberculosis, sarcoidosis, diagnosis, bronchoscopy, biomarkers, and radiography. All studies were reviewed, and 69 references from 1990 to 2023 were found to be relevant. Key Content and Findings: Innovative laboratory tests are essential for distinguishing between pulmonary sarcoidosis and TB. The Xpert MTB/RIF assay diagnoses TB with 98% sensitivity and 89% specificity. Loop-mediated isothermal amplification (LAMP) and simultaneous amplification and testing method for Mycobacterium tuberculosis rRNA (SAT-TB) are also highly sensitive and specific for TB diagnosis. Several novel tests, such as the difference of immune complexes for the ESAT-6/SFP-10 antigen in vitro with dynamic light scattering (DLS), lung tissue-based molecular markers, and the blood transcriptome, are promising for differentiating TB from sarcoidosis. Conclusions: Recent advancements in laboratory investigations, non-invasive procedures, and invasive procedures play an important role in the diagnosis of sarcoidosis in TB-endemic areas. However, further study is needed to evaluate the diagnostic performance of all tests in terms of their competency in distinguishing between TB and sarcoidosis.
RESUMEN
BACKGROUND: Bronchial thermoplasty (BT) is a non-pharmacological intervention in severe asthma with a well-known mechanism of reducing airway smooth muscle. However, its effect on airway inflammation remains uncertain. OBJECTIVE: To investigate the effect of BT on bronchoalveolar lavage fluid (BALF) cytokines and chemokines in severe asthma patients before BT, after the first BT, and 12 weeks after BT. METHODS: Ten severe asthma patients were recruited, and BALF was obtained from right lower lobe before BT, after the first BT, and 12 weeks after BT. BALF analytes were measured and values were compared among the time points. Lung function, asthma control test (ACT), and asthma quality of life questionnaire (AQLQ) were also measured. RESULTS: Tumor necrosis factor (TNF)-α concentration was significantly decreased after the first BT and significantly increased at 12 weeks after BT. Interleukin-6 (IL-6) and TNF-related apoptosis inducing ligand (TRAIL) concentration were significantly increased at 12 weeks after BT. There were no significant changes in Regulated upon activation, normal T-cell expressed and secreted (RANTES) and transforming growth factor-beta1 (TGF-ß1) concentration over time after BT. At 12 weeks after BT, there were significantly greater improvements in the scores on AQLQ (3.93 ± 0.88 to 5.3 ± 0.99, p = 0.002) and ACT (13.6 ± 3.27 to 19 ± 4.44, p = 0.002). The lung function did not differ significantly between pre- and post-BT. CONCLUSIONS: BT has limited effect on TNF-α, IL-6, TRAIL, RANTES, and TGF- ß1 in BALF suggesting that its clinical benefit is not primarily related to this local airway inflammation. The effect on long-term airway inflammation probably needs further studies.
RESUMEN
The role of as-needed inhaled short-acting ß2-agonists (SABAs) in the management of asthma has become a subject of debate due to differing opinions in the professional community relating to the use of SABAs. In this article, we summarize the current position of SABAs when used as reliever medications and examine the challenges to appropriate use including a critique of the data that have led to the condemnation of SABA used as a reliever. We consider the evidence for the appropriate use of SABA as a reliever together with practical solutions to ensure such use, including identifying patients at risk of misusing their SABA relievers and managing issues of inhaler technique and treatment adherence. We conclude that inhaled corticosteroid (ICS)-based maintenance treatment with SABA used as-needed as a reliever is an effective and safe treatment for patients with asthma, with no scientific evidence of a causal link between SABA use as a reliever and mortality or serious adverse events (including exacerbations). Increased SABA use warns of a deterioration in asthma control, and patients at risk of misusing their ICS and SABA medication should be rapidly identified to ensure they are receiving adequate ICS-based controller therapy. Appropriate use of ICS-based controller therapy and as-needed SABA should be encouraged and promoted with educational activities.

OBJECTIVE: To investigate the knowledge and perceptions of physicians on the role of modeling studies in asthma, using a modified Delphi procedure. METHODS: Group opinions among a panel of respiratory experts were obtained using two online questionnaires and a virtual scientific workshop. A consensus was pre-defined as agreement by >75% of participants. RESULTS: From 26 experts who agreed to participate, 22 completed both surveys. At the end of the process, the panel rated their own understanding of modeling as good (77%) but that among physicians in general as poor (77%). Participants agreed that data from modeling studies should be used, at least sometimes, to inform treatment guidelines (91%) and could be useful for guiding clinical decisions (100%). Perceived barriers to using modeling studies were 'A lack of understanding' (81%) and 'A lack of standardized methodology' (82%). Based on data from two modeling studies, no consensus was reached on physicians recommending regular inhaled corticosteroids (ICS) versus as-needed therapy for patients with mild asthma, whereas 77% agreed that they would recommend regular ICS over maintenance and reliever therapy for ≥80% of their patients with moderate asthma. No consensus was reached on the value of modeling data in relation to empirical data. CONCLUSION: There is overall support among respiratory experts for the usefulness of modeling data to guide asthma treatment guidelines and clinical decision making. More publications on modeling data using robust models and accessible terminology will aid the understanding of physicians in general and help clarify the evidence-based value of modeling studies.

BACKGROUND: In locoregional esophageal carcinoma (EC), airway involvement is the most common route of extraesophageal metastasis. The prognosis remains poor even with a multimodality approach. Although airway stenting is well known for restoration of the airway, the survival benefit is still lacking. METHODS: A total of 37 of patients with airway involvement from EC who underwent airway stenting at a single institution from 2015 to 2020 were retrospectively reviewed. Survival curves after stent placement among different groups were analyzed using Kaplan-Meier method. RESULTS: Of 37 patients, 34 were male, and the mean age was 58.9 years (42 to 80). EC was commonly located at midesophagus (51.4%). The site of airway involvement was left main bronchus (48.6%), trachea (32.4%), multiple sites (16.2%), and right main bronchus (2.7%). The nature of airway involvement was tumor invasion (91.9%), compression (62.2%), and fistula (37.8%). Twenty-three patients (62.2%) had airway involvement at the time of esophageal cancer diagnosis. Only 4 patients underwent esophageal stenting. The median survival time after stent placement was 97 days (5 to 539). Chemotherapy and/or radiotherapy were given before stent placement in 18 patients (48.6%). Treatment-naive before airway stenting and diagnosis of airway involvement at the same time of EC diagnosis were independent predictors for the increased survival after stent placement ( P <0.05). Poststent treatment was associated with improved survival ( P =0.002). CONCLUSION: In patients with malignant airway involvement from EC who underwent airway stenting, the prognostic predictors for improved survival were treatment-naive status, receiving treatment after airway stenting, and early-onset of airway involvement.

INTRODUCTION: Short-acting ß2-agonist (SABA) reliever overuse is common in asthma, despite availability of inhaled corticosteroid (ICS)-based maintenance therapies, and may be associated with increased risk of adverse events (AEs). This systematic literature review (SLR) and meta-analysis aimed to investigate the safety and tolerability of SABA reliever monotherapy for adults and adolescents with asthma, through analysis of randomized controlled trials (RCTs) and real-world evidence. METHODS: An SLR of English-language publications between January 1996 and December 2021 included RCTs and observational studies of patients aged ≥ 12 years treated with inhaled SABA reliever monotherapy (fixed dose or as needed) for ≥ 4 weeks. Studies of terbutaline and fenoterol were excluded. Meta-analysis feasibility was dependent on cross-trial data comparability. A random-effects model estimated rates of mortality, serious AEs (SAEs), and discontinuation due to AEs (DAEs) for as-needed and fixed-dose SABA treatment groups. ICS monotherapy and SABA therapy were compared using a fixed-effects model. RESULTS: Forty-two studies were identified by the SLR for assessment of feasibility. Final meta-analysis included 24 RCTs. Too few observational studies (n = 2) were available for inclusion in the meta-analysis. One death unrelated to treatment was reported in each of the ICS, ICS + LABA, and fixed-dose SABA groups. No other treatment-related deaths were reported. SAE and DAE rates were < 4%. DAEs were reported more frequently in the SABA treatment groups than with ICS, potentially owing to worsening asthma symptoms being classified as an AE. SAE risk was comparable between SABA and ICS treatments. CONCLUSIONS: Meta-analysis of data from RCTs showed that deaths were rare with SABA reliever monotherapy, and rates of SAEs and DAEs were comparable between SABA reliever and ICS treatment groups. When used appropriately within prescribed limits as reliever therapy, SABA does not contribute to excess rates of mortality, SAEs, or DAEs.

Background: Asthma and allergic rhinitis (AR) can coexist and cause disabilities. This study aimed to assess the association between AR, asthma control, asthma-related quality of life, and other comorbidities. Methods: A cross-sectional study was conducted in adults with asthma in six hospitals in Thailand. The outcomes were association of asthma control assessed by the asthma control test (ACT), AR, and asthma comorbidities. Not-well-controlled asthma was defined as ACT scores ≤22. The severity of AR was determined by visual analog scale (VAS). Severe AR was defined as VAS ≥5. Asthma-related quality of life (AQLQ), comorbidities, and total IgE were recorded. Results: A total of 682 asthmatic patients were included. Median (IQR) age was 58.0 (47.0-64.0) years. 69.9% were female. Not-well-controlled asthma was present in 44.7%. The prevalence of AR was 86.1%. Moderate/severe persistent AR was diagnosed in 21.7% and severe AR was diagnosed in 30.2% of the patients. Inhaled corticosteroid-containing regimens were prescribed in 97.7% of patients. Intranasal corticosteroid and antihistamine were prescribed in 65.7 and 31.7%, respectively. Patients with not-well-controlled asthma had higher body mass index, VAS scores, proportions of pollution exposure, aeroallergen sensitization, severe AR, nasal polyp, urticaria, food allergy, gastroesophageal reflux disease, depression and anxiety, peptic ulcer, and asthma exacerbations, but younger age, lower AQLQ scores, and lower FEV1. Correlation was found between AR severity and ACT (r = -0.461, p < 0.001), AQLQ (r = -0.512, p < 0.001), and total IgE (r = 0.246, p < 0.023). Multiple regression analysis revealed that ACT, AQLQ, and percentage of FEV1/FVC were significantly associated with severe AR. Conclusion: Allergic rhinitis is prevalent in Thai asthmatic patients. AR severity is associated with asthma control, quality of life, and pulmonary function. Comprehensive care is essential for patients with uncontrolled asthma, particularly when coexisting with conditions.
RESUMEN
To study the clinical presentation, management and mechanism of fractured outer metallic tracheostomy tube presenting as tracheobronchial foreign body. A retrospective chart review patients with fracture outer metallic tracheostomy tube. Data regarding the patients' demographic data, diagnosis, clinical presentation, type of tracheostomy tube and site of fracture were analyzed. Total 4 cases of fracture outer metallic tracheostomy tube were found. There were 3 males and 1 female, average age 52.75 years, range 31-76 years. The common presentation were dyspnea, intolerable cough and decreased breath sound in 4(100%), 2(50%) and 2(50%) cases. The most serious presentation was cardiac arrested 1 case. The dislodged tube were retrieved by flexible and rigid bronchoscopy. The most common site of fracture were outer tube at mid shaft 3 cases (75%). All of this site had corrosion. Only 1 case (25%) was fracture at junction between neck plate and tube without corrosion. The average time of usage metallic tracheostomy tube was 24 days, range 3-34 days. Fracture tracheostomy tube is rare and serious medical emergency. The patients, caregivers and physicians should recognition and prompt action. Flexible or rigid bronchoscopy via tracheostoma can successfully removal the dislodge part. The mechanism of fracture may come from several factors. The defective manufacturer, stagnation of alkaline bronchial secretion, recurrence process of removal, cleaning and boiling of the tube can cause mechanical stress and degradation of passive film of the tubes. The patient education regarding the maintenance and regular checked up can possibly extinguish this complication.
RESUMEN
Pulmonary cysticercosis is one of the rare complications of cysticercosis that occurs worldwide, especially in developing countries. Its clinical presentation can range from asymptomatic, pleural effusion, and constitutional symptoms to incidental pulmonary nodule. Here, we report pulmonary cysticercosis detected as a pulmonary nodule in computed tomography. Positron emission tomography revealed that the nodule was non-FDG avidity. However, the slow-growing pattern of the nodule raised a concern to the clinician to achieve definite diagnosis by surgical biopsy. Histopathological examination revealed cysticercosis. The patient was treated with praziquantel.
RESUMEN
Over the past years, lung cancer has been one of the vital cancer-related mortalities worldwide and has inevitably exhibited the highest death rate with the subsequent need for facile and convenient diagnosis approaches to identify the severity of cancer. Previous research has reported long-chain aldehyde compounds such as hexanal, heptanal, octanal, and nonanal as potential biomarkers of lung cancer. Herein, the helicene dye-encapsulated ethyl cellulose (EC@dye-NH) nanosensors have been applied for the potentially sensitive and specific detection of long-chain aldehydes in aqueous media. The sensors contain the intrinsic hydrazide group of dye-NH, which is capable of reacting an aldehyde group via imine formation and the EC backbone. This offers the synergistic forces of hydrophobic interactions with alkyl long-chain aldehydes, which could induce self-assembly encapsulation of EC@dye-NH nanosensors and strong fluorescence responses. The addition of long-chain aldehyde would induce the complete micellar-like nanoparticle formation within 15 min in acetate buffer pH 5.0. The limit of detection (LOD) values of EC@dye-NH nanosensors toward heptanal, octanal, and nonanal were 40, 100, and 10 µM, respectively, without interference from the lung fluid matrices and short-chain aldehydes. For practical applicability, this sensing platform was developed for quantification of the long-chain aldehydes in lung fluid samples with 98-101% recoveries. This EC@dye-NH nanosensor was applied to quantify nonanal contents in lung fluid samples. The results of this method based on EC@dye-NH nanosensors were then validated using standard gas chromatography-mass spectrometry (GC-MS), which gave results consistent with the proposed method. With intracellular imaging application, the EC@dye-NH nanosensors demonstrated excellent intracellular uptake and strong green fluorescence emission upon introducing the nonanal into the lung cancer cells (A549). Thus, the developed nanosensing approach served as the potential fluorescent probes in medical and biological fields, especially for lung cancer disease diagnosis based on highly selective and sensitive detection of long-chain aldehydes.
RESUMEN
The multidisciplinary experts in Thailand developed an asthma management recommendation that was relevant to low-middle income countries (LMICS). Populations level consideration about asthma management is emphasized. The healthcare systems, access to and availability of treatments as well as the asthma populations vary from country to country in LMICS. The feasibility in clinical practice for implementation is also a major issue. For these reasons, the practice guidelines that are relevant to local contexts are essential to improve better asthma control. Furthermore, integrative and collaboration between asthma experts and the public health sector to implement and discriminate such guidelines will help to achieve these challenging goals. The topics covered include the current asthma situation in Thailand and the Asia-Pacific region, the definition of asthma, asthma diagnosis, assessment of asthma patients, asthma treatment - both pharmacological and non-pharmacological, management of asthma exacerbation, management of asthma comorbidities, treatment of asthma in special conditions, severe and uncontrolled asthma, Thai alternative medicine and asthma, and asthma and coronavirus disease-19 (COVID-19).

Cytokine release syndrome (CRS) is known to be associated with severe coronavirus disease 2019 (COVID-19). Multiple anti-inflammatory therapies such as tocilizumab, corticosteroids, intravenous immunoglobulin (IVIG), and haemoadsorption or haemoperfusion have been used to combat this life-threatening condition. However, immunocompromised hosts are often omitted from research studies, and knowledge on the clinical efficacy of these therapies in immunocompromised patients is therefore limited. We report two cases of immunocompromised patients with severe COVID-19-related CRS requiring mechanical ventilation who were treated with multimodality treatment consisting of tocilizumab, IVIG, and haemoperfusion. Within 48 h, both patients showed clinical improvement with PaO2:FiO2 ratio and haemodynamic stability. Both survived to discharge. There were no adverse events following these therapies. In conclusion, combined therapeutic modalities, possibly tailored to individual inflammatory profiles, are promising treatment for severe COVID-19 infection in the immunocompromised host. Timely administration of adjunctive therapies that alleviate overwhelming inflammation may provide the best outcome.
RESUMEN
BACKGROUND: Salbutamol-induced lactic acidosis is a rare presentation that could manifest in specific clinical context as acute asthmatic attack treatment. An increase of glycolysis pathway leading to pyruvate escalation is the mechanism of hyperlactatemia in ß2-adrenergic agonist drug. CASE PRESENTATION: A 40-year-old man who had poor-controlled asthma, presented with progressive dyspnea with coryza symptom for 6 days. He was intubated and admitted into medical intensive care unit due to deteriorated respiratory symptom. Severe asthmatic attack was diagnosed and approximate 1.5 canisters of salbutamol inhaler was administrated within 24 h of admission. Initial severe acidosis consisted of acute respiratory acidosis from ventilation-perfusion mismatch and acute metabolic acidosis resulting from bronchospasm and hypoxia-related lactic acidosis, respectively. The lactate level was normalized in 6 h after hypoxemia and ventilation correction. Given the lactate level re-elevated into a peak of 4.6 mmol/L without signs of tissue hypoxia nor other possible etiologies, the salbutamol toxicity was suspected and the inhaler was discontinued that contributed to rapid lactate clearance. The patient was safely discharged on the 6th day of admission. CONCLUSION: The re-elevation of serum lactate in status asthmaticus patient who had been administrated with the vast amount of ß2-adrenergic agonist should be considered for salbutamol-induced lactic acidosis and promptly discontinued especially when there were no common potentials.

We report a case of COVID-19 in kidney transplant patient in Thailand. A 58-year-old 2 years post-kidney transplant recipient, with maintenance immunosuppression of tacrolimus, mycophenolate mofetil (MMF), and prednisolone, presented with acute diarrhea which followed by fever on day 12. Symptoms of pneumonia together with lymphopenia from complete blood count were developed on day 7 after onset of fever with the x-ray finding of bilateral multifocal patchy infiltration. COVID-19 infection has been confirmed by reverse real-time polymerase chain reaction (PCR) in nasal swab as well as found in stool. Darunavir together with ritonavir, hydroxychloroquine, azithromycin, and favipiravir was initiated on the first day of admission at primary hospital. Patient has been transferred to our hospital on day 2 of admission in which tacrolimus together with MMF was discontinued. High-flow nasal cannula oxygen therapy was required on days 4-5 of hospitalization. Tocilizumab was administered after rising of serum IL-6 level. Symptoms of pneumonia were improved in which no oxygen treatment required from day 10 of hospitalization. Drug interaction between tacrolimus and anti-viral treatment leads to severely high level of tacrolimus which caused reversible acute kidney injury (AKI) after supportive treatment.

BACKGROUND: When severe, COVID-19 shares many clinical features with bacterial sepsis. Yet, secondary bacterial infection is uncommon. However, as epithelium is injured and barrier function is lost, bacterial products entering the circulation might contribute to the pathophysiology of COVID-19. METHODS: We studied 19 adults, severely ill patients with COVID-19 infection, who were admitted to King Chulalongkorn Memorial Hospital, Bangkok, Thailand, between 13th March and 17th April 2020. Blood samples on days 1, 3, and 7 of enrollment were analyzed for endotoxin activity assay (EAA), (1 â 3)-ß-D-glucan (BG), and 16S rRNA gene sequencing to determine the circulating bacteriome. RESULTS: Of the 19 patients, 13 were in intensive care and 10 patients received mechanical ventilation. We found 8 patients with high EAA (≥ 0.6) and about half of the patients had high serum BG levels which tended to be higher in later in the illness. Although only 1 patient had a positive blood culture, 18 of 19 patients were positive for 16S rRNA gene amplification. Proteobacteria was the most abundant phylum. The diversity of bacterial genera was decreased overtime. CONCLUSIONS: Bacterial DNA and toxins were discovered in virtually all severely ill COVID-19 pneumonia patients. This raises a previously unrecognized concern for significant contribution of bacterial products in the pathogenesis of this disease.
RESUMEN
A 35-year-old Thai women (gravida 3, para 0) at 36 weeks and five days of gestation was admitted to a delivery room due to premature rupture of membrane. She was diagnosed with Escherichia coli with extended-spectrum beta-lactamase (ESBL) chorioamnionitis and septic shock leading to signs of fetal distress. She underwent emergency caesarean section. Post-operatively, the patient developed severe acute respiratory distress syndrome (ARDS), disseminated intravascular coagulation (DIC), massive pulmonary haemorrhage, and intra-abdominal bleeding. Lung protective strategy and recruitment manoeuvres were applied; however, her oxygenation and haemodynamic parameters worsened. Twenty consecutive hours of prone positioning was performed as a rescue procedure to improve patient's oxygenation and allow the patient to undertake surgical re-exploration for abdominal compartment syndrome management safely. Neither high ventilator setting nor re-positioning was needed after the second operation.
