Effectiveness of Eupatorium perfoliatum 30C in Prevention of Dengue Fever and Acute Febrile Illness during 2017 Dengue Outbreak in Urban Slums of Delhi: A Prospective, Open-Label, Community-Based, Parallel Cohort Study

Objective: This study was undertaken to assess the effectiveness of Eupatorium perfoliatum (EP) 30C on the incidence of dengue fever and acute febrile illness (AFI) during the 2017 dengue outbreak. Methods: We conducted a prospective, open-label, community-based parallel cohort study involving apparently healthy individuals residing in 06 urban slums (JJ colony) of Delhi. The participants were enrolled in two cohorts – the medicine cohort (MC) and the control cohort (CC). Participants in MC were given weekly one dose of EP 30C for 10 weeks along with Information, Education and Communication (IEC) material regarding dengue. Participants in the CC were provided with the IEC material only. The primary outcome measure was the incidence of dengue fever as per case definitions notified in the national guidelines for clinical management of dengue fever by the Government of India during the 10 weeks follow-up period. The secondary outcome measures were the incidence of AFI and the hospitalization of confirmed dengue cases. Results: The analysis included 40,769 participants residing in 06 slum clusters of Delhi out of which 28,321 participants were in MC and 12,448 participants were in CC. The incidence of laboratory-confirmed dengue in the MC was 2.57 per 10,000 person-weeks (95% confidence interval [CI], 2.02–3.22) in comparison with 7.55 per 10,000 person-weeks (95% CI, 6.12–9.21) in the CC. The incidence of AFI in the MC was 19.66 per 10,000 person-weeks (95% CI, 18.07–21.36) in comparison with 40.96 per 10,000 person-weeks (95% CI, 37.48–44.67) in the CC. The overall protective effect of EP against laboratory-confirmed dengue was 65.77% (95% CI, 53.37–74.87; p = 0.0001) and against AFI was 52.58% (95% CI, 46.37–58.07; p = 0.0001). Hospitalization reported in the MC was nil as against 4.35% in the CC. No dengue-related case fatalities were reported from either cohort. None of the participants from the MC reported any adverse events owing to the prophylactic intervention. Conclusion: The study concludes that EP 30C was able to prevent dengue significantly. Randomized controlled trials are needed to confirm or refute our findings.

Spatiotemporal Dengue Fever Incidence Associated with Climate in a Brazilian Tropical Region

Dengue is a serious infectious disease worldwide and a climate-sensitive disease. Thus, our goals were to (i) evaluate the relationship between dengue incidence and meteorological variables (rainfall and air temperature); (ii) identify the spatiotemporal pattern of dengue incidence in the municipalities of Mato Grosso from 2001 to 2020; and (iii) verify the spatial dependence of dengue incidence in the dry and wet seasons. We used dengue data from 2001 to 2020, monthly rainfall estimates from GPM, and daily air temperature estimates from ERA-5. The municipalities of the Mato Grosso state are included in 16 healthcare territories. The seasonal rainfall pattern indicates that the peak of the dengue endemic occurred in the wet season. However, drier and/or warmer places had a lower incidence of dengue in the dry season. Furthermore, a lagged effect of meteorological variables on dengue incidence has been identified, ranging from 0 to 7 months. Hotspot areas were identified which might have the potential for an intense spreading of dengue in Mato Grosso. They were mainly concentrated in the healthcare territory of Teles Pires (ID 14) in the dry season, while they were concentrated in the healthcare territories of Garças Araguaia (ID 5), Oeste (ID 11), and Teles Pires (ID 14) in the wet season. In addition, they are located in the Am climate and in the Amazon Forest and Brazilian savanna biomes, which have higher dengue incidence values. These results help to highlight which municipalities decision-makers must intervene in the public health system to prevent and control future epidemics.

Mapping the stability of febrile illness hotspots in Punjab from 2012 to 2019- a spatial clustering and regression analysis

IntroductionFebrile illnesses (FI) represent a typical spectrum of diseases in low-resource settings, either in isolation or with other common symptoms. They contribute substantially to morbidity and mortality in India. The primary objective was to study the burden of FI based on Integrated Disease Surveillance Programme (IDSP) data in Punjab, analyze geospatial and temporal trends and patterns, and identify the potential hotspots for effective intervention.MethodsA retrospective ecological study used the district-level IDSP reports between 2012 and 2019. Diseases responsible for FI on a large scale, like Dengue, Chikungunya, Malaria (Plasmodium Falciparum, P. Vivax), Enteric fever, and Pyrexia of Unknown Origin (PUO), were included in the analysis. The digital map of Punjab was obtained from GitHub. Spatial autocorrelation and cluster analysis were done using Moran’s I and Getis-Ord G* to determine hotspots of FI using the incidence and crude disease numbers reported under IDSP. Further, negative binomial regression was used to determine the association between Spatio-temporal and population variables per the census 2011. Stable hotspots were depicted using heat maps generated from district-wise yearly data.ResultsPUO was the highest reported FI. We observed a rising trend in the incidence of Dengue, Chikungunya, and Enteric fever, which depicted occasional spikes during the study period. FI expressed significant inter-district variations and clustering during the start of the study period, with more dispersion in the latter part of the study period. P.Vivax malaria depicted stable hotspots in southern districts of Punjab. In contrast, P. Falciparum malaria, Chikungunya, and PUO expressed no spatial patterns. Enteric Fever incidence was high in central and northeastern districts but depicted no stable spatial patterns. Certain districts were common incidence hotspots for multiple diseases. The number of cases in each district has shown over-dispersion for each disease and has little dependence on population, gender, or residence as per regression analysis.ConclusionsThe study demonstrates that information obtained through IDSP can describe the spatial epidemiology of FI at crude spatial scales and drive concerted efforts against FI by identifying actionable points.

Experience in conducting an epidemiological analysis of dengue incidence in the Socialist Republic of Vietnam using geographic information systems

Aim: To identify regional epidemiological features of dengue fever and substantiate approaches to conducting epidemiological surveillance for this infection taking into account the regional features of its distribution and risk factors affecting its formation.Materials and methods: Retrospective epidemiological analysis of dengue incidence in the provinces of the Socialist Republic of Vietnam from 2017 to 2022. To conduct the epidemiological analysis of dengue incidence, a free version of the GIS Axioms (ГИС Аксиомы) program and the Google Earth application were used.Results: It was noted that cases of dengue fever were registered in all 63 provinces of the country, however, the dynamics of incidence levels had wide spatial and temporal ranges. Excepting Hanoi (189.6 0/0000), dengue incidence in the northern provinces are lower than those in the southern provinces. The highest average long-term incidence of dengue fever was observed in Da Nang (659.8 0/0000), Binh Duong (623.3 0/0000), Quang Binh (565.5 0/0000), Ba Ria-Vung Tau (554.6 0/0000) and Khanh Hoa (544.8 0/0000). The results of a comparative analysis of dengue incidence and the main factors influencing it in the adjacent, the incidences of dengue fever of which are significantly different from each other, are shown. The application of geoinformation systems for epidemiological analysis has been demonstrated. It has been established that the distribution of the population of Vietnam differs greatly between the administrative regions of the country, and the use of population density for epidemiological analysis and forecasting of the epidemiological situation of infectious diseases, including dengue fever, can lead to incorrect results.Conclusion: The epidemiological situation of dengue fever in Vietnam is characterized by high incidence rates, their wide ranges of spatial and temporal variability, and geographical heterogeneity. The use of GIS technologies is one of the promising approaches for epidemiological analysis and monitoring of dengue fever, as well as other infectious diseases.

DENV-2 NS1 promotes AMPK-LKB1 interaction to activate AMPK/ERK/mTOR signaling pathway to induce autophagy

The global incidence of dengue fever has gradually increased in recent years, posing a serious threat to human health. In the absence of specific anti-dengue drugs, understanding the interaction of Dengue virus (DENV) with the host is essential for the development of effective therapeutic measures. Autophagy is often activated during DENV infection to promote viral replication, but the mechanism of how DENV's own proteins induce autophagy has not been clarified. In this study, we first preliminarily identified DENV-2 NS1 as the most likely viral protein for DENV-2-induced autophagy with the help of molecular docking techniques. Further experimental results confirmed that DENV-2 NS1 regulates DENV-2 infection of HUVEC-induced autophagy through the AMPK/ERK/mTOR signaling pathway. Mechanistically, DENV-2 NS1 mainly interacted with AMPK by means of its Wing structural domain, and NS1 bound to all three structural domains on the AMPKα subunit. Finally, the experimental results showed that DENV-2 NS1 promoted the interaction between LKB1 and AMPKα1 and thus activated AMPK by both increasing the expression of LKB1 and binding LKB1. In conclusion, the results of this study revealed that DENV-2 NS1 protein served as a platform for the interaction between AMPK and LKB1 after DENV-2 infection with HUVEC, and pulled AMPK and LKB1 together to form a complex. LKB1 to form a complex, promoting LKB1 action on the kinase structural domain of AMPKα1, which in turn promotes phosphorylation of the Thr172 site on the AMPK kinase structural domain and activates AMPK, thereby positively regulating the AMPK/ERK/mTOR signaling pathway and inducing autophagy. The present discovery improves our understanding of DENV-2-induced host autophagy and contributes to the development of anti-dengue drugs.

IMMUNE SYSTEM SUSCEPTIBILITY OF DEPRESSED PATIENTS TO DENGUE VIRUS INFECTION: CASE REPORT

Introduction – Depression is a health problem that causes mortality and morbidity. The incidence of depression aged ≥ 15 years is as much as 6.1%. Another health problem is dengue hemorrhagic fever (DHF), where 71,700 confirmed cases of DHF have been reported in Indonesia as of July 2020. The study at Mayo Hospital Lahore explained that there is a correlation between DHF infection and depression. There is no study to describe susceptibility of the immune system of depressed patients to dengue virus infection in Indonesia. Methods – Presented the case of patient, female, 19 years old with initial diagnosis and management of DHF from internal medicine departement. We use a Hamilton Depression Rating Scale (HDRS) questionnaire to evaluated status mental patient. Results – The results of the patient's HDRS questionnaire showed that the patient had moderate depression. The results of the psychiatric examination showed depressive affect, anhedonia, anenergy and feeling useless with an onset 1 month before suffering from DHF. The patient was given pharmacotherapy and psychotherapy from psychiatry. Discuss – Late diagnosis and treatment of depression causes prolonged stress in the body. This condition triggers HPA axis and sympathetic nervous system which will increase levels cortisol, and increased secretion of anti-inflammatory cytokines can reduce inflammatory response to incoming pathogens, so that body will be susceptible to dengue virus infection. Management of depression at a young age with psychotherapy and pharmacotherapy use SSRI and benzodiazepines for reduce the risk of suicide. Conclusion – Late diagnosis and treatment of depression makes immune system vulnerable to pathogens or infections. Interdisciplinary collaboration is needed so that the enforcement of psychiatric cases in hospitalization becomes more accurate and for further research to be carried out on the correlation of depression with the incidence of dengue hemorrhagic fever with a different research design. Keywords: depression, DHF, HPA axis, proinflammatory cytokines, cortisol.

Climatic variations and the incidence of dengue fever in Bandung, Indonesia

Indonesia is a country endemic to dengue fever—and Bandung is one of the cities in Indonesia that is endemic to dengue fever. There have been efforts to control mosquitoes, one of which is by eradicating their nests, but this step has not optimally reduced the incidence of cases. The increase in cases is thought to have been caused by climatic variations. This study aimed to analyze the relationship between climatic variations (temperature, humidity, and rainfall) and the incidence of dengue hemorrhagic fever (DHF). This study used a correlation design and was carried out in Bandung. This study used secondary data. The samples were taken from data on the number of DHD patients from 2016 to 2021 recorded at the Health Office of Bandung, as well as temperature, humidity, and rainfall data from the Central Bureau of Statistics of Bandung from 2016 to 2021. The correlation between variables was assessed using the person correlation test. Climatic variations that are significantly correlated with the incidence of dengue hemorrhagic fever (DHF) are minimum temperature (p=0.020, and r=-0.658), maximum temperature (p=0.006, and r=-0.739), minimum humidity (p=0.000, and r=0.825), and rainfall (p=0.037, and r=0.605). The increase in the incidence of dengue hemorrhagic fever (DHF) is caused by climatic variations (temperature, humidity, and rainfall). Therefore, it is recommended that mosquito control and DHF surveillance program should be strengthened during the season following the rainy (wet) season.

For the case of using the third order of contiguity, a total of six high-low, two low-high spatial clusters and one low-low spatial cluster were successfully identified. Conclusions: the study results has proven the effective use of the global Moran’s I statistic, Moran’s I scatterplot and local Moran’s I statistic in the identification of spatial clustering of dengue hemorrhagic fever incidence.

Analysis of entomological indicators and distribution of <i>Aedes aegypti</i> larvae in dengue endemic areas

Background. The cause of dengue fevers endemicity is vector larvae density, with Aedes aegypti as the prime vector. Bandung municipality is a high dengue fever endemic area. Hence, studying the habitat characteristics of the Aedes mosquito is essential to controlling the populations of mosquitos.
 Purpose. This study aimed to identify the aedes larvae breeding sites and the relationship between the breeding risk index, hygiene risk index, maya index, and the existence of larvae with the incidence of dengue fever.
 Method. The design used in this research was a cross-sectional survey. The sampling technique used simple random sampling. The quantity of the sample was 544 directly observed houses.
 Results. The entomological parameters obtained were house index (23.89%), container index (7.81%), Breteau index (50.73%), and larva free number (76.10%). The breeding risk index, hygiene risk index, and maya index are in the low category. The chi-square test conveyed that the breeding risk index, maya index, and the existence of larvae were significantly associated with the incidence of dengue fever.
 Conclusion. The entomological index may influence the high incidence of dengue fever. These findings and results may help the authorities to improve mosquito nest eradication in attempts to prevent dengue transmission.
