A prospective 3 year study of clinical spectrum and outcome of dengue fever in ICU from a tertiary care hospital in North India.

BACKGROUND AND AIMS: The incidence of specific complications and adverse outcomes in dengue patients needing admission to intensive care units (ICU) may be quite variable in different regions of India presumably because of different strains of dengue virus or due to re infection. METHODS: Patients admitted with acute febrile illness (AFI) with either positive IgM antibody or NS1 antigen for dengue were enrolled. Data were collected for 3 years (2015-2017). A total of 313 patients with acute febrile illness were admitted in the study period (2252 total ICU admissions). A total of 137 (43.76%) cases were serologically proven as dengue fever. RESULTS: Median age (IQR) of study population was 36.0 (26.0-52.0) years. Liver (65.7%) was the main organ involved followed by acute kidney Injury (AKI) (18.6%). Dengue Shock Syndrome (DSS) was found in 18.6% of cases. Fifty-two patients died and the crude mortality was 38.0%. On multivariate analysis APACHE Score <10, thrombocytopenia, hepatic dysfunction, AKI and dengue shock syndrome (DSS) were associated with the risk of mortality. CONCLUSION: This study in ICU patients showed high mortality in relatively younger patients. Liver (in the form of raised Bilirubin) was the most common organ dysfunction. The need to recognise early warning signs for ICU admission is highlighted.

Candida auris candidaemia in an intensive care unit - Prospective observational study to evaluate epidemiology, risk factors, and outcome.

PURPOSE: To determine the prevalence of Candida auris candidaemia in our ICU patients and its molecular epidemiology. METHODS: A prospective observational study was conducted on candidaemia in our ICU patients over 18 months during 2016-2017. Demographics, underlying disease, risk factors, antifungal therapy and outcome were studied. Risk factors of C. auris and non-auris candidaemia were compared. RESULTS: During the study period, among 108 candidaemia cases recorded, the incidence was 6.75/1000 ICU bed days. C. auris topped the list (n = 42, 39.9%), followed by C. tropicalis (34.3%), and C. parapsilosis (15.7%). On bivariate analysis prior antibiotic therapy, long central line days, mechanical ventilation and length of ICU stay were significant risk factors for C. auris candidaemia compared to non-auris candidaemia. Multivariate analysis showed underlying respiratory and neurological diseases as significantly associated with risk of C. auris candidaemia. Fluconazole, amphotericin B, and caspofungin resistance were noted in 97.0%, 93.7% and 3% of C. auris isolates respectively. CONCLUSION: Longer duration of central line days, prior antibiotic use, mechanical ventilation and prolonged ICU stay were important risk factors associated with C. auris candidaemia along with underlying respiratory or neurological disease. The isolates are non-clonal in origin, but they belong to a single clade.

A Rare Case of Combined Pulmonary Cryptococcosis and Cryptococcal Meningitis in Renal Allograft Recipient.

Invasive cryptococcosis is the third most common invasive fungal infection among organ transplant recipients.1 The most frequently encountered clinical manifestation is cryptococcal meningoencephalitis (CM) which may be easily missed because of varying clinical presentations. 1-year mortality is estimated at 20-30% even with long-term consolidated antifungal therapy. Here we report a case of combined pulmonary and cryptococcal meningitis in a renal allograft recipient. This case illustrates the difficulty of estimating the real extent of the disease when only clinical features are considered. The patient presented with nonspecific symptoms. Chest computed tomography (CT) scans revealed multiple pulmonary nodular shadows. The CT-guided biopsy of the pulmonary nodule clinched the diagnosis of pulmonary cryptococcosis (PC). The central nervous system (CNS) cryptococcosis was proved by positive culture and crypto-LA antigen in the cerebrospinal fluid (CSF). HOW TO CITE THIS ARTICLE: Shastri PS, Kumar R, Gupta P.
