Background:The swine flu (H1N1) with rapid spread and panic in population is truly global pandemic, affected mainly younger population. There is need to accumulate evidence regarding patient's intensive care parameters for effective management of newer strains of influenza viral infections. Hence an observed retrospective record analysis of confirmed H1N1 patients admitted to intensive care unit (ICU) of a tertiary care centre is done.Aims:The study was designed to study the profile and pattern of H1N1 patients admitted to ICU and to study the distribution and associated factors with treatment outcomes.Materials and Methods:The demographic, clinical, and laboratory data of 32 (RT-PCR confirmed) H1N1cases were collected and analyzed using Fischer's exact test/paired t test between survivors and nonsurvivors to know their significance. This data included criteria for admission to ICU, type of lung injury, mode of oxygenation, antiviral, and other drugs used.Results:There were 11 males and 21 female. Age ranged from 19 to 72 years. Age group of 15–45 years had most cases (78%) and mortality (60%). Most common symptoms were fever and breathlessness (100%). The mean duration of breathlessness was statistically significant (P = 0.037) between two groups. Most common signs were tachycardia and tachypnea. The 75% cases developed acute respiratory distress syndrome (ARDS), of this 16% survived. Among these fatal cases nine were positive for procalcitonin (PCT) (P = 0.006). The rest of 25% developed acute lung injury (ALI) and recovered completely (P = 0.0001).Conclusion:Fever and breathlessness were the main presenting complaints. Tachypnea and tachycardia as clinical signs predict development of respiratory complications. Arterial blood gas analysis (ABG) and PaO2/FiO2 were important in deciding severity of lung injury and mode of ventilation. ARDS was observed to be the main cause of mortality in this study. Serum PCT level estimation is useful in determining outcome.
BACKGROUND The study was conducted in an attempt to correlate serum uric acid levels with Killip class i.e. severity of heart failure in patients with acute myocardial infarction and to assess any influence of serum uric acid levels on predicting prognosis in patients with acute myocardial infarction. Ischaemic heart disease, particularly acute myocardial infarction is one of the leading causes of death across the world accounting for 12.7 % of global mortality. Low and middle-income countries are facing 80 % of the global burden of ischaemic heart disease death. Since the pathophysiology of acute myocardial infarction is complicated, proper risk stratification is essential for appropriate management and better outcome. Serum uric acid levels (SUA) have been correlated with coronary artery calcification and atherosclerosis. High SUA levels also have been identified as a risk marker for cardiovascular disease development, progression and mortality. METHODS The study design was a one-year cross-sectional study. 100 patients admitted with acute myocardial infarction within one day of the start of symptoms in the Department of Cardiology & Medicine were included from September 2018 to September 2019. In this study, patients with known causes of elevated uric acid levels (chronic kidney disease, gout, haematological malignancy, hypothyroidism, metabolic syndrome, myeloproliferative disease, lymphoproliferative disease, drugs– pyrazinamide, diuretics, ethambutol, ethanol, malignancy, G6PD deficiency and psoriasis) were included. Patients on drugs which raise serum uric acid e.g., salicylates (2 gm / d, hydrochlorothiazide, pyrazinamide), and chronic alcoholics were not included. Patients were further subjected to investigations like serum uric acid, ECG, 2D echo and other routine investigations. Urine albumin levels, troponin I, chest x-ray, fundoscopy, and fasting lipid profile were done. Investigation reports were analysed with the clinical profile and the data was compiled and appropriate statistical test was applied. RESULTS There were more cases of myocardial infarction above 40 years as compared to below 40 years of age and males (69 %) were more as compared to females (31 %) with the commonest presentation as chest pain. Majority of the patients had inferior wall myocardial infarction (IWMI) (40 %) and most (91 %) of the patients had left ventricular (LV) dysfunction (mild, moderate and severe). More patients with Killip class III and IV had abnormal uric acid levels as compared to class I, and II. Among 27 patients who expired, 23 were in Killip class III and IV (13 in Killip class III and 10 in class IV) and the mean serum uric acid levels of expired patients were elevated on all the 3 days with maximum elevation on day 1. CONCLUSIONS Patients with higher Killip class had higher levels of serum uric acid in comparison to patients of lower Killip class. Serum uric acid level in association with Killip class is a good predictor of the severity of heart failure and short-term mortality after myocardial infarction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
