RESUMO
Background: The extent of short-acting Beta-2-agonist (ß2-agonist) (SABA) use across Asian countries is not well documented. As part of the SABA use IN Asthma (SABINA) III study, we assessed SABA prescriptions and clinical outcomes in patients with asthma from Asia. Methods: This cross-sectional study recruited patients (aged ≥12 years) with asthma from 8 Asian countries. Data on disease characteristics and asthma treatments were collected using electronic case report forms. Patients were classified by practice type (primary or specialist care) and investigator-defined asthma severity (per Global Initiative for Asthma [GINA] 2017 recommendations). The association of SABA prescriptions with clinical outcomes was analyzed using multivariable regression models. Results: Overall, 3066 patients were analyzed, with a mean (standard deviation) age of 51.8 (16.7) years; of these patients, 2116 (69%) were female, 2517 (82.1%) had moderate-to-severe asthma and 2498 (81.5%) and 559 (18.2%) were treated in specialist and primary care, respectively. In total, 1423 (46.4%) patients had partly controlled/uncontrolled asthma, with 1149 (37.5%) patients experiencing ≥1 severe asthma exacerbation in the previous year. Overall, 800 (26.7%) patients were prescribed ≥3 SABA canisters in the previous year, which is regarded as overprescription and was associated with a significantly decreased odds of at least partly controlled asthma and increased incidence rates of severe exacerbations (P < 0.01 for both associations). Conclusion: The findings from this cohort of predominantly specialist-treated patients with asthma indicate SABA overprescription in at least 1 in every 4 patients, and this overprescription is associated with poor clinical outcomes. These data highlight the need for adherence to recently updated asthma treatment recommendations in Asia.
RESUMO
BACKGROUND: Recent evidence suggested that the higher titers of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody from convalescent plasma donors contributed to the clinical improvement in coronavirus disease 2019 (COVID-19) patients. However, the titers of anti-SARS-CoV-2 antibodies varied in each individual, and the precise factors that might govern such variation have not been elucidated. OBJECTIVES: To assess the factors associated with high titers of anti-SARS-CoV-2 antibody among COVID-19 convalescent plasma (CCP) donors. METHODS: A cross-sectional study was conducted in Saiful Anwar General Hospital, Malang, Indonesia. Information of interest including demographic characteristics, clinical symptoms, comorbidities, laboratory findings, and the titers of anti-SARS-CoV-2 antibody among COVID-19 CCP donors were collected. The correlation was assessed using multiple logistic regression. RESULTS: A total of 50 COVID-19 CCP donors with the titers of anti-SARS-CoV-2 antibody of more than 1:320 and 33 donors with the titers of less than 1:320 were analyzed. Our analysis revealed that CCP donors with history of cough, fever, dyspnea, and pneumonia significantly had higher titers of anti-SARS-CoV-2 antibody compared to asymptomatic donors. Moreover, CCP donors with elevated levels of eosinophils and immature granulocytes and low levels of albumins had higher levels of anti-SARS-CoV-2 antibody. The titer of antibody was not affected by comorbidities of donors. CONCLUSIONS: CPP donors who had experience of symptomatic COVID-19 with high eosinophils level, high immature granulocytes and low albumin level have higher titers of anti-SARS-COV-2 antibody than those who experienced asymptomatic COVID-19. Our current findings may be used as the additional baseline criteria for selecting the donors of CCP for the management of COVID-19.
RESUMO
Coronavirus disease 2019 (COVID-19) has emerged as a pandemic across the world. Hypercoagulability status in COVID-19 is one of the causes of complication from severe COVID-19 with a high risk of arterial thrombosis. Acute Limb Ischemia is a vascular emergency caused by sudden decrease in the arterial perfusion. We report the case of a 53-year-old male patient with COVID-19 Pneumonia, diagnosed with Acute Limb Ischemia. From clinical examination, which included anamnesis, physical examination, and laboratory results as well as chest X-rays, a suspicion of Acute Limb Ischemia was found in a patient with COVID-19 pneumonia. The SARS-CoV-2 real time PCR examination showed positive results. In this patient, the diagnosis of Acute Limb Ischemia with Covid-19 Pneumonia was established through a multidisciplinary approach covering the fields of pulmonology, cardiology, and thoracic and cardiovascular surgery.
