Background & objectivesAcute respiratory distress syndrome (ARDS) is a common disorder in critically ill patients and is associated with high mortality. There is a paucity of literature on this condition from developing countries. This prospective observational study was designed to find out the aetiology, outcomes and predictors of mortality in ARDS.MethodsSixty four consecutive patients who satisfied American-European Consensus Conference (AECC) definition of ARDS from medical Intensive Care Unit (ICU) of a tertiary care centre in New Delhi, India, were enrolled in the study. Demographic, biochemical and ventilatory variables were recorded for each patient. Baseline measurements of serum interleukin (IL)-1β, IL-6, tumour necrosis factor-alpha (TNF-α), procalcitonin (PCT) and high sensitivity C-reactive protein (hsCRP) were performed.ResultsCommon causes of ARDS included pneumonia [44/64 (68.7%)], malaria [9/64 (14.1%)] and sepsis [8/64 (12.5%]. Eight of the 64 (12.5%) patients had ARDS due to viral pneumonia. The 28-day mortality was 36/64 (56.2%).Independent predictors of mortality included non-pulmonary organ failure, [Hazard ratio (HR) 7.65; 95% CI 0.98-59.7, P=0.05], Simplified Acute Physiology Score (SAPS-II) [HR 2.36; 95% CI 1.14-4.85, P=0.02] and peak pressure (P peak ) [HR 1.13; 95% CI 1.00-1.30, P = 0.04] at admission.Interpretation & conclusionsBacterial and viral pneumonia, malaria and tuberculosis resulted in ARDS in a considerable number of patients. Independent predictors of mortality included non-pulmonary organ failure, SAPS II score and P peak at baseline. Elevated levels of biomarkers such as TNF-α, PCT and hsCRP at admission might help in identifying patients at a higher risk of mortality.

Background Diagnostic importance of asymptomatic cryptococcal antigenemia is being increasingly recognized in the last few years. Recently, WHO (World Health Organization) has recommended routine screening of CrAg (cryptococcal antigen) among PLHA with CD4 ≤100/mm
3 , albeit this procedure is not yet adopted by many developing countries including India. Methods We conducted a prospective observational study in a large tertiary care center of North India, upon ethical clearance. Latex agglutination test was performed to assess serum CrAg levels, followed by the lumbar puncture for detection of CrAg levels in the CSF. We analyzed the prevalence and treatment outcomes of cryptococcal antigenemia among PLHA with CD4 ≤ 100 cells/mm3 . Detailed clinical examination was conducted, with follow-up of upto 3 months. Multivariate analysis was performed for the estimation of risk factors. Results The mean age (years) and BMI (kg/m2 ) of all the participants were 41.4 ± 11.2 and 22.1 ± 2.6, respectively. Notably, the mean CD4 count (cu.mm) at the time of recruitment was 62.3 ± 20.5. Noteworthy, 62 (60.8%) of the patients were ART naïve. We found 9.8% (n = 10) of the patients were positive for serum CrAg, and only 2.9% (n = 3) had clinical features of meningitis and 6.8% (n = 7) were asymptomatic (subclinical) CrAg positive. Strikingly, 3.9% (n = 4) of the asymptomatic cryptococcal antigenemia patients were also positive for CrAg in CSF, with 1.9% (n = 2) were only serum CrAg positive, and 1 patient was lost to follow-up (Graph 1). Multivariate analysis revealed that patients with long duration of HIV (P = 0.04), headache symptoms (P = 0.004) and possessing features of meningismus (P value=0.08) are more likely to be CrAg positive. Conversely, patients on fluconazole were protective against cryptococcal antigenemia (P = 0.1) as shown in Table 1. Overall mortality observed was 11.3% among advanced HIV patients. Moreover, mortality in CrAg-positive patients was 33.3% in comparison to CrAg-negative patients who had 9% (P = 0.06) in 3-months follow-up. Conclusion Cryptococcal antigenemia is common (9.8%) among patients with CD4 count ≤100/mm3 in India. Screening for CrAg should be made routine for PLHA with CD4 count ≤100/mm3 and if required preemptive treatment to be given in this regard. Disclosures All authors: No reported disclosures.

The clinical profile and risk factors for mortality in dengue fever have evolved over the years. The all-cause mortality in admitted dengue patients is around 6%. We aimed to evaluate the recent change in trends of the clinical characteristics and risk factors for in-hospital mortality in adults with dengue fever. This is a retrospective study on adults with confirmed dengue fever admitted in a medical unit of a tertiary care center in North India. Medical records of confirmed dengue fever patients admitted between January 2011, and December 2016 were reviewed. Chi-squared tests with Bonferroni correction for multiple testing were used to identify risk factors for mortality. 232 records were included, of which 66.8% were males. The mean age was 31.6 ± 14 years. There were 17 deaths with an all-cause mortality rate of 7.3% with 76.5% being classified as severe dengue at admission. Among the 17 mortality cases, dyspnea (47%), tachypnea (86.7%), leucocytosis (58.8%), raised urea (80%), and elevated serum creatinine (52.9%) at presentation were significantly associated with mortality (p < 0.001). Shock at any time during the hospital stay (58.8%) was also found to be significantly associated with mortality (p < 0.001). We found that dyspnea, tachypnea, acute kidney injury, and leucocytosis at presentation was significantly associated with in-hospital mortality. Based on our results, we recommend aggressive management of patients with severe dengue and those with mild/moderate disease with the above risk factors. [ABSTRACT FROM AUTHOR]
