Abstract

Dengue is one of the infectious diseases which is endemic in the tropical and sub-tropical country. The disease found in Indonesia Surabaya, 1968. The symptoms of Dengue virus infections are two kinds, first DF (Dengue Fever), second DHF (Dengue Hemorrhagic Fever). This infectious disease transmitted by Aedes aegypti mosquito. Mosquitoes breed in clean water areas. More than 100,000 cases of DF/DHF ccurred in Indonesia every year. The purpose of this study were to provide information and the spread of dengue virus types in Surabaya from January 2013 to September 2013. The nalysis technique used to determine the type of dengue virus nfectionwas used PCR (Polymerase Chain Reaction). The results obtained 69% DENV-1, 27% DENV-2 isolates, 4% isolates DENV-3, and 0% DENV-4 isolates.

Abstract

Background: In 2012, serotype of Dengue Virus had changed from Den-2 and Den-3 to Den-1. In 5–10 years ago, serotype of Den-1 case showed a mild clinical manifestation; but now as a primary case it can also show severe clinical manifestation. One of indicator is an increasing liver enzyme, AST and ALT, with level more than 100–200 U/L. Aim: To getting a better solutions for this problem. Method: Obsevasional Study had been done in medical faculty of Airlangga University (Dr. Soetomo and Soerya hospital) Surabaya on Mei–August 2012. There were 10 cases of dengue virus infection were studied, 5 cases got Ringer Acetate solution (Group A) and 5 cases got Ringer Lactate solution (Group B). The diagnosis was based on criteria WHO 2009. Result: Five cases of Dengue Virus Infection had showed a liver damage soon after using Ringer Lactate solution; AST and ALT were increasing more than 100–200 U/L; but the other 5 cases showed better condition. It might be due to use Ringer Acetate that did not have effect for inducing liver damage. By managing carefully, all of the cases had shown full recovery and healthy condition when being discharged. Conclusion: Using Ringer Acetate as fluid therapy in Dengue Virus Infection is better to prevent liver damage than using Ringer Lactate.

Abstract

Dengue virus (DENV) is a significant pathogen emerging worldwide as a cause of infectious disease. Antidengue treatments are urgently required to control the emergence of dengue. DENV is a mosquito-borne disease responsible for acute systemic diseases and serious health conditions. DENVs were distributed in the tropical and sub-tropical areas and transmitted to humans by Aedes agypty and Aedes albopictus. Dengue vaccine or antiviral has not yet been clinically approved for humans, even though there have been great efforts toward this end. Antiviral activity against DENV is an important alternative for the characterization and development of drugs. Metal–organic compounds were reported to exhibit fungicidal, bactericidal, and antiviral activities its inhibitory activity was not significant, at high concentration it was more toxic to replicating cells than to stationary cell monolayers of Vero cells. The aim of this study is to investigate the antiviral effects of Cobalt(II)–Morin complex. This compound was further investigated for its inhibitory effect on the replication of DENV-2 in Vero cells. The replication of DENV was measured by enzyme-linked immunosorbent assay and the value of selectivity index (SI). SI was determined as the ratio of the 50% cytotoxic concentration (CC50) to the 50% inhibitory concentration (IC50). The IC50 value of the Cobalt(II)–Morin complex for DENV-2 was 3.08 µg/ml, and the CC50 value of the complex for Vero cells was 3.36 µg/ml; thus, the SI value was 1.09. The results of this study demonstrate the antidengue serotype 2 inhibitory activity of Cobalt(II)–Morin complex and its high toxicity in Vero cells. Further studies are not required before Co(II)–Morin can be applied in the treatment of DENV-2 infections.
