ABSTRACT

One of the key reasons for the poor performance of natural enemies of honeydew-producing insect pests is mutualism between ants and some aphid species. The findings demonstrated that red wood ant, Formica rufa Linnaeus (Hymenoptera: Formicidae) had a deleterious impact on different biological parameters of the lady beetle, Hippodamia variegata Goeze (Coleoptera: Coccinellidae). H. variegata laid far fewer eggs in ant-tended aphid colonies, laying nearly 2.5 times more eggs in ant absence. Ants antennated and bit the lady beetle eggs, resulting in significantly low egg hatching of 66 per cent over 85 per cent in ant absent treatments. The presence of ants significantly reduced the development of all larval instars. The highest reduction was found in the fourth larval instar (31.33% reduction), and the lowest in the first larval instar (20% reduction). Later larval instars were more aggressively attacked by ants than earlier instars. The first and second larval instars stopped their feeding and movement in response to ant aggression. The third and fourth larval instars modified their mobility, resulting in increased ant aggression towards them. Adult lady beetles were shown to be more vulnerable to ant attacks than larvae. However, H. variegata adults demonstrated counterattacks in the form of diverse defensive reaction behaviours in response to F. rufa aggression.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the clinical outcome, microbiological outcome and safety profile of CSE-1034, a novel combination of Ceftriaxone, Sulbactam and EDTA in patients with complicated urinary tract infections (cUTI). MATERIALS AND METHODS: This was a randomized, controlled, open-labeled Phase-3 trial with the primary objective of assessing the efficacy and safety of CSE-1034 versus Ceftriaxone for the empirical treatment of cUTI. Adult cUTI patients were randomized to receive either intravenous dose of CSE-1034 or Ceftriaxone. The primary end point was composite cure rate (clinical response and bacterial eradication) in mMITT population at test of cure (TOC) visit. Secondary measures included verification of primary endpoint across other visits in different population sets, safety of patients and treatment duration. RESULTS: Overall, 204 patients were enrolled in the study and received one of the two treatments. At primary endpoint (TOC visit), the composite cure rate was much higher in CSE-1034 treatment arm compared to Ceftriaxone arm i.e. 97% (68/70) vs 83% (58/71) (treatment difference 12.6%; 95% CI: 5.9% to 26.4%). The adverse events (AEs) rates reported in two treatment arms were 21% in CSE-1034 and 36% in Ceftriaxone groups. Additionally, the treatment duration in CSE-1034 arm was significantly less (P < 0.05). CONCLUSIONS: CSE-1034 3 g every 24 h showed a high favorable clinical and bacteriological response, and 95% CI around the treatment difference prove the superiority of CSE-1034 vs. Ceftriaxone for the treatment of cUTI. Therefore, CSE-1034 provides an effective alternative in the treatment of patients with cUTI.

ABSTRACT

Abstract Objective: In India, Elores (CSE-1034: ceftriaxone + sulbactam + disodium edetate) was approved as a broad spectrum antibiotic in year 2011 and is used for management of Extended Spectrum Beta Lactamases/Metallo Beta lactamases infections in tertiary care centers. The objective of this study was to investigate the efficacy of this drug in patients with Extended Spectrum Beta Lactamases/Metallo Beta lactamases infections and identify the incidence of adverse events in real clinical settings. Methods: This Post Marketing Surveillance study was conducted at 17 centers across India and included 2500 patients of all age groups suffering from various bacterial infections and treated with Elores (CSE1034). Information regarding demographic, clinical and microbiological parameters, dosage and treatment duration, efficacy and adverse events (AEs) associated with the treatment were recorded. Results: A total of 2500 patients were included in the study and efficacy was evaluated in 2487 patients. In total, 409 AEs were reported in 211 (8.4%) patients. The major AEs reported were vomiting (3.0%), pain at injection site (2.5%), nausea (2.3%), redness at site (1.96%), thrombophlebitis (1.4%). Of total reported AEs, 40 (5.3%) AEs were reported in pediatric, 310 (20.6%) in adult, and 59 (23.6%) in geriatric group. No AE belonging to grade IV or V was reported in any patient. In terms of efficacy, 1977 (79.4%) patients were cured, 501 (20.1%) patients showed clinical improvement and 5 (0.2%) patients were complete failure. The treatment duration varied from 5 to 7 days in different patients depending on the infection type. Conclusion: In this post-marketing surveillance study, CSE-1034 was found to be an effective and safe option against Pip tazo and meropenem in management of patients with multi-drug resistant (MDR) bacterial infections under routine ward settings.
