A study was undertaken with an aim to find out the levels of circulating high density lipoprotein (HDL) cholesterol and ratio of this fr action to total blood cholesterol in lepromatous leprosy patients before and after drug therapy. The healthy contacts of these patients were considered as control subjects of the study. The subjects were distributed in three groups on the basis of their age. HDL-cholesterol to total cholesterol ratio was significantly raised in both treated and untreated patients in all three groups compared to the healthy controls. The data may explain the low risk of myocardial infarction due to atherosclerosis in leprosy patients.
13The emergence of multiple carbapenemases and the consequent multi drug resistance in bacteria 14 constitute a grave concern in the management of critical care patients and also in community 15 acquired infections. Detection of carbapenamase activity helps to understand the possible 16 mechanism(s) of carbapenem resistance in the microorganism. Identification of carbapenemases 17 is currently being done by various phenotypic methods and molecular methods. However, 18 innovative biochemical and spectrophotometric methods are desirable as they will be easy to 19 perform, affordable and rapid. Recently a novel chromogenic method called CarbaNP test was 20 introduced to screen for carbapenemases in clinical isolates of gram negative pathogens. We 21 adopted this assay: (i) to detect the total carbapenemase activity (ii) to measure the relative rates 22 of hydrolysis of imipenem by class A, B and D carbapenemases with inhibitors (iii) to confirm 23 the genotype by PCR and (iv)for direct differential detection of various carbapenemases in 24 uncultured clinical sample like tracheal aspirate. The study included 75 culture isolates and 153 25 purulent tracheal aspirates. All isolates were screened by our optimized protocol and also 26 genotyped by PCR. This adopted assay showed good sensitivity and correlation with 27 conventional phenotyping and genotyping. Our protocol offers the fastest way to identify the 28 pathogen by PCR but also its carbapenemase profile directly from uncultured clinical samples in 29 2 less than 4h. Our protocol is currently being validated on other types of clinical specimens in our 30 laboratory.

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.
