Abstract

Complication in Plasmodium falciparum malaria is associated with endothelial damage and overproductionof free radicals (oxidative stress) by activated neutrophils and endothelial cells. Red fruit (Pandanus conoideus) oil  has a very high antioxidant content, therefore it may neutralize free radicals and prevent endothelial damage. The aim of this research is to prove that red fruit (Pandanus conoideus) oil reduce Reactive Oxygen Intermediate (ROI) production  of endothelial cells exposed to severe malaria patient serum and neutrophils from healthy donor. Endothelial cells from human umbilical veins were coincubated with serum from severe malaria patient and with neutrophils from healthy donor  (positive control group). HUVEC’s normal was used as negative control,  where as  the experimental groups were given with red fruit oil in different concentrations (2.8%, 5.7% dan 11.3% ). The Reactive Oxygen Intermediate (ROI) production of  endothelial cells was semiquantitatively measured by using NBT-reduction assay and the score of ROI was counted. The results were statistically analyzed with ANNOVA (p<0.01). The rate of ROI production of endothelial cells was markedly increased after incubation with patient serum and neutrophils.

Abstract

Malaria is still a major problem for developing countries, including Indonesia. One approach to overcome this disease is prevention by vaccination. However, there is still no effective malaria vaccine that is applicable. The ideal malaria vaccine is a combination vaccine that can prevent the pre-erythrocytic cycle, the erythrocytic cycle and transmission process. Salivary vector-based vaccine has the potential to be developed as a malaria vaccine because it can prevent transmission process and also decrease the morbidity of the disease. Saliva from Anopheles contains vasomodulator and immunomodulatory components, that are required in the blood feeding process, but in the same time it could enhance the transmission of the malaria parasite. If the component in the salivary vector can increase pathogen infection, then vaccinating the host with its anti-substances can control the transmission of pathogens (Transmision Blocking Vaccine). Anopheles sundaicus is an important vector of malaria in coastal areas of Java, Bali, Sumatra, Kalimantan and West Nusa Tenggara islands. Repeated exposures of Salivary Gland Extract (SGE) from this vector have been proven to be able to decrease parasitemic rates in mouse model for malaria in our study. The objective of this research is to determine and localize the immunogenic protein from SGE of An. sundaicus as the first step for the characterization of its immunomodulatory component. Mosquito salivary gland protein profile of An.sundaicus was determine by SDS-PAGE. Determination of salivary glands immunogenic proteins was conducted by Western Blotting with IgG from people living from endemic area as primary antibody. Out of 15 bands appeared in SDS PAGE ranging from 24 kD to 138 kD, only two protein bands with  molecular weights of 68 and 37 kDa were the most immunogenic. Those immunogenic proteins were consistent recognized by pooled serum of people as well as by individual response. Keywords: malaria, saliva, vector, immunogenic protein, vaccine

Abstract

Tuberculosis (TB) is a contagious infectious disease caused by the bacteria Mycobacterium tuberculosis. More than 80% of TB cases attack the pulmonary organs and the rest are extra-pulmonary TB. Indonesia is one of the countries with the high number of tuberculosis cases besides India, China, the Philippines, and Pakistan. Aside from being a country with a high TB incidence, Indonesia is also an endemic country for helminth infections, especially Soil-Transmitted Helminths (STH). The high prevalence of STH infections in Indonesia allows STH coinfection in TB patients to cause decreasing immunity, thus affecting the outcome of TB infection. STH infection is very closely related to environmental sanitation. The purpose of this study was to identify and determine the association of environmental sanitation risk factors to the coinfection of Soil-Transmitted Helminths (STH) in tuberculosis patients in Panti District, Jember Regency. This type of research was observational research with cross-sectional analytic design. Of the 49 TB patients who were undergoing treatment at the Panti Health Center, 32 people were willing to be respondents, but only 25 people collected stool samples. Fisher's test results showed that the incidence of intestinal co-infection in TB patients in Panti District, Jember Regency was 12% and was caused by two STH species, namely A. lumbricoides and Hookworm. Environmental sanitation in TB patients was mostly good, e.g 54.5% of respondents had good environmental sanitation, but there was no significant association between environmental sanitation and the incidence of intestinal co-infection in TB patients in Panti District, Jember Regency (p> 0.05).

Abstract

Helminthiasis caused by soil transmitted helminths (STH) are still a serious health problem in the world and in Indonesia. Indonesia has a prevalence that varies between 2.5%-62%. This infection can cause blood disorders such as leukocytosis, eosinophilia, and changes in hemoglobin levels. The purpose of this study was to describe the leukocyte count of coffee plantation workers that infected by STH. This research was an observational descriptive study, using a cross sectional design and was conducted at the coffee plantation in Silo subdistrict. Stool examination was conducted by the concentration method (sedimentation and flotation) to determine the presence of STH infection, while for leukocyte count, we used the differential count method. The results of examination on 101 feces samples showed 26.7% (27/101) of workers were positively infected with STH, with details of the STH type of hookworm by 92.6% (25/27), and the remaining were double infections by Ascaris lumbricoides and hookworm as much as 7.4 % (2/27). Examination of leukocyte count showed, 17 workers with hookworm infection had abnormal leukocyte count i.e eosinophilia and neutrophilia, while 8 workers were normal. All workers with double infection (2 workers) had abnormal leukocyte count i.e eosinophilia and neutrophilia. These results can be influenced by the chronicity of the infection or the intensity of the infection. Keywords: Chronic Kidney Disease, sodium, re-use hemodialyzer

Abstract

The salivary gland of female Anopheles mosquito has important role in malaria transmission by salivary proteins that enhancing Plasmodium transmission. The mosquito saliva contains vasomodulatory and immunomodulatory components that inhibit the physiological response of the host. Therefore, the pathogen infects the host without any resistance. The salivary proteins also induce the production of antibody IgG in the host after exposed by the Anopheles mosquito bites repeatedly. This study aims to measured the antibody response of inhabitants living in malaria endemic areas (Kalirejo viilages, Kokap, Kulonprogo) to salivary gland proteins of An. maculatus and An.sundaicus. The level of antibody response was measured by ELISA and analyzed with T test or Anova test for normal distribution of data and Mann Whitney test or Kruskal Wallis test for the data were not normally distributed. The result showed that the level of anti-salivary gland homogenate IgG from sera of people living in malaria endemic area was significantly higher than people living in non-malaria endemic area and negative control (p<0.05). Sera from inhabitants living in Kalirejo village showed that the level of antibody response to both salivary gland homogenate of An.sundaicus and An.maculatus were not significantly different (p<0.05). It was concluded that exposure to An.maculatus and An.sundaicus bites repeatedly could trigger the production of anti-salivary gland proteins IgG antibodies that recognized antigenic proteins from the salivary glands.

Abstract

Background: Plasmodium falciparum Erythrocyte Membrane Protein 1 (PfEMP1) is an important protein responsible for the pathogenesis of severe malaria, including cerebral malaria. The protein is highly diverse. The CIDR1α-PfEMP1 binds endothelial protein receptor (EPCR) and may associated with the brain swelling in childhood malaria.Objective: To analyze the CIDR1α-PfEMP1 from Indonesian isolate and determine its association with cerebral malaria outcome.Methods: Fifteen blood samples of clinically mild to severe malaria-patient were collected for DNA extraction. Malaria diagnosis was conducted microscopically by Giemsa-stained thin blood smear. The CIDR1α domain was amplified by PCR using specific primer and PCR product was sequenced. The nucleotide sequences were analyzed by NCBI blast, DNASIS MAX 3 and translated into amino acid sequences using Expasy Translation Tool.Results: One out of fifteen samples was severe malaria case and infected with P.  falciparum, the rest were clinically mild to moderate malaria and infected with pure P. falciparum or mixed infection of P. falciparum and P. vivax. Amplification for CIDR1α domain resulted a single band of + 550 bp from a severe sample only. Sequencing of PCR product on both strands read 524 nucleotides and BLAST analysis confirmed as CIDR1α sequence. Multiple alignment showed 74-78% nucleotide sequence similarity with reference sequences, but amino acid sequences presented 23.5% homologous.Conclusion: An identified CIDR1α domain only from severe case implicating the potential association with the severe outcome including cerebral malaria, but the highly diverse of the domain needs further studies on the interaction with the pathological-causing receptor in the host.

Abstract

Globally, helminthiasis is one of the infectious diseases that are often associated with the incidence of tuberculosis. Helminth co-infection modulates the immune system of TB patients by reducing Th-1 response that functions as protector against Mycobacterium tuberculosis. This condition disrupts the process of eliminating bacteria so that its development becomes more progressive. The impact is the activation of latent TB and the success of TB treatment. A Soil-transmitted Helminth (STH) is a group of intestinal worms that often infect humans. Previous studies prove that environmental sanitation and personal hygiene are risk factors associated with STH infection. The study to determine the relationship of environmental sanitation and personal hygiene with the incidence of STH co-infection in TB patients at Puskesmas Puger, Jember in September until December 2019. This study uses a cross-sectional design. The sampling technique uses total sampling. A total of 32 TB patients met the criteria as study sample. The data analysis uses Fisher Test. Results showed the prevalence of STH co-infection was relatively low (18.8%); most of the respondents had good environmental sanitation and personal hygiene conditions. Bivariate analysis showed p-value (0,476) for environmental sanitation and p-value (1,000) for personal hygiene. This study concludes that there is no correlation between environmental sanitation, personal hygiene, and STH co-infection in TB patients at Public health center in Puger.

Abstract

ABSTRACT Pediculosis capitis is a scalp disease caused by obligate ectoparasite (mite or lice) infection of Pediculus humanus var. capitis. This disease is a contagious disease that influenced by environment and behavior, so it becomes a dominant public health problem in densely populated environment like in boarding school. Some risk factors that cause Pediculosis capitis are; sex, educational level, hair wash frequency, use of comb or hair accessories together, use of bedding or bed together, hair length, and hair type. This study aims to determine the most dominant incidence, analyze the risk factors, and know the biggest risk factors to the incidence of Pediculosis capitis in santri at Pondok Pesantren Miftahul Ulum, Jember. The type of research that used was observational analytics with case control design conducted on 287 samples of SMP and SMA Miftahul Ulum students who fulfilled the inclusion and exclusion criterias. From this research, the proportion of Pediculosis capitis incidence was 214 respondents (74,6%), and then analyzed by Chi-Square test, it was found that the variables had significant relationship (p <0,05) to Pediculosis capitis occurrence, among others; sex, hair wash frequency, use of comb or hair accessories together, use of bedding or bed together, hair length and hair type. The result of logistic regression test shows that sex was the most biggest variable (p value = 0,000). Keywords: Pediculosis capitis, risk factors, boarding school
