Abstract

The incidence rate (IR) of dengue hemorrhagic fever (DHF) in Indonesia has increased in recent years and still causes a health problem. Makassar, as one of the big cities in Indonesia, is also experiencing of DHF cases. According to the Health Office of Makassar City, DHF cases during 2014 – 2016 has increased from 139 to 250 cases. The defense mechanism of dengue virus in transovarial transmission from female mosquitoes to eggs is estimated to be one of the factors that increase the rate of DHF. In addition, the circulation of the Aedes aegypti mosquitoes can also affect the increase of the rate. This study aims are to identify ovitrap index and to find out how much the vertical transmission of dengue virus by measuring the minimum infection rate (MIR) and the distribution of four dengue virus serotype in Ae. aegypti mosquitoes in the city of Makassar, South Sulawesi, as well as their association with the incidence rate (IR) in the area. This observational research uses ecological study with cross-sectional approach. The samples of the study are male and female mosquitoes from Ae.aegypti eggs obtained from the installation of ovitrap  in 30 urban villages in Makassar. Dengue virus identification was performed using a reverse transcriptase polymerase chain reaction (RT-PCR). These results showed that the ovitrap index (IO) was in the range of 0 - 66.7%. The average value of the ovitrap index outside the house (44.44%) was greater than inside house (37.22%). The results of identification of dengue virus using RT-PCR showed negative results as indicated by the non-formation of a band on 75 pools male and 78 pools female Ae. aegypti mosquitoes after electrophoresis. The results of this study indicated that the Ae. aegypti mosquito in Makassar City showed a tendency to lay eggs outside the house due to the habit of the people who put rain water shelters outside the house which could become breeding place for Ae. aegypti mosquitoes. This study also showed that there was no transovarial transmission of DENV found in male and female Ae. aegypti mosquitoes in Makassar City during November 2017 until January 2018.

Abstract

Indonesia is still included in high endemic area of malaria infection. Early detection as well as appropriate and quick treatment is needed to be able to prevent and treat malaria in Indonesia. Laboratory examination using a microscopic method is still used as the gold standard to diagnose malaria cases. However, the morphology similarity of some Plasmodium species and the number of parasites that can be seen under microscopy causes malaria diagnosis become difficult if only relying on microscopy diagnostic method. The purpose of this study is to analyze the sensitivity and specificity of nested PCR compared to microscopic examination in diagnosing malaria cases. A cross-sectional study has been carried out in some areas of Indonesia and the microscopic analysis as well as nest PCR was done in Laboratory of Parasitology and Laboratory of Central Biomedical Faculty of Medicine, Universitas Brawijaya, Malang East Java Indonesia. A total of 149 blood samples from patients with clinical symptoms of malaria had been obtained from Sumatra, Sulawesi and East Java during December 2011 to December 2013. From 149 sample, 81.9% samples were diagnosed malaria positive by microscopy examination, whereas the PCR results showed that 90.6% of samples were positive. Nested PCR sensitivity is 97.5%, and microscopy 88.2%. Nested PCR specificity is 40.7%, whereas microscopy 78.5%. PPV and NPV for nested PCR are 88,2% and 78.5% respectively, and for microscopy are 97.5% and 40.7% respectively. Nested PCR has a higher sensitivity than microscopy in diagnosing malaria and is able to detect mixed infection better than microscopic examination. However, it is statistically less specific than microscopy examination.

Abstract

Idiopathic nephrotic syndrome (INS) is the most prevalent autoimmune glomerular disease in children and its pathogenesis is correlated with high level of interleukin 6 (IL-6) and low level of vitamin D. This study was aimed to investigate the difference of vitamin D and IL-6 level in steroid resistant nephrotic syndrome (SRNS), steroid sensitive (SSNS), and idiopathic nephrotic syndrome (INS). This research was designed as cross sectional involving 45 subjects which then divided into 3 groups as follows: SRNS, SSNS, and INS. A level of serum 25 (OH)D was measured by Enzyme-linked Immuno Assay Method then categorized as sufficiency, insufficiency, and deficiency. Level of IL-6 serum was measured by ELISA method. Results showed that IL-6 level was significantly different among three groups, in which SRNS had the highest value (ANOVA, p < 0.05). Further analysis demonstrated that IL-6 level correlated with steroid resistance (Spearman correlation test, p = 0.000, r = 0.692). Vitamin D status was significantly different among three groups (Chi square, p = 0.03) and associated with steroid resistance (Spearman correlation test, p = 0.000, r = 0.568). Moreover, IL-6 level associated with 25 (OH) D level in SRNS group (Pearson correlation test, p = 0.020, r = 0.591) but not in the SSNS and INS group. We conclude that IL-6 levels were significantly higher in SRNS group as compared to other groups. Otherwise, vitamin D status were significantly lower in SRNS compared with other groups. An IL-6 level was negatively correlated with vitamin D status in patients with NS, specifically in SRNS group.

Abstract

Nephrotic syndrome (NS) is an autoimmune disease that correlates to the imbalance of regulatory T cells (TReg). This study was aimed to investigate the effect of vitamin D as adjuvant therapy of TReg population in pediatric nephrotic syndrome. This study was designed randomized clinical trial, double blind, with pre- and post-test control groups involving 15 subjects newly diagnosed with NS. Subjects were divided into 2 groups, namely K1 for group treated with prednisone+vitamin D and K2 group for prednisone treatment only. The population of TReg in peripheral blood mononuclear cells (PBMC) was analyzed using flowcytometry. Vitamin D serum level was measured through ELISA method. Results showed that there was a significant elevation of TReg (independent t-test, p = 0.010) in K1 group, which was higher than in K2 group. The Pearson test in the K1 group showed that vitamin D level was positively correlated with TReg (p = 0.039, r = 0.779).

Abstract

The vitamin D role on the immune response of systemic lupus erythematosus (SLE) patient is mediated by vitamin D receptor (VDR). Low level of vitamin D correlated with disease activity in SLE patients, and circulating levels of activated vitamin D (1,25(OH)2D) contribute to VDR protein levels and its function. The objective of this study was to determine the correlation between vitamin D status with expression of VDR in peripheral blood mononuclear cell (PBMC) and the disease activity in SLE patients. The Research Subjects were 15 SLE patients (ACR 1997 criteria) from the Rheumato-Immunology Division, dr. Saiful Anwar Hospital, Malang and 5 healthy controls. Serum vitamin D (25(OH)D3) level was assessed using ELISA method. VDR expression in PBMC was assessed using immunocytochemistry technique. The disease activity was measured by Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score. This study showed no difference on VDR expression in PBMC between patient and healthy control group, but patient with vitamin D deficiency had lower VDR expression in PBMC than the other group. No difference on SLEDAI score between the group. Vitamin D status correlated positively with VDR expression in PBMC (p < 0,035, r = 0,473). However vitamin D status did not correlate with disease activity scores (p = 0,686).

Abstract

 This research aims to examine the effect of Artemisin and Moringa oleifera leaf extract combination on the percentage of CD4+ and CD8+ T cell of mice infected with P.berghei. CD4+ and CD8+ T cells have important role in eliminating Plasmodium intracellular parasite that causes malaria infection. Artemisin is a potent antimalarial that kills the parasite through free radicals production. Excessive free radicals damage the immune cells, including CD4+ and CD8+ T cells. Flavonoid (quercetin and kaempferol) bioactive on Moringa leaves is a powerful antioxidant and anti-inflammatory, and is expected to prevent and decrease the adverse effects of Artemisin. This experimental post-test group research was conducted on six groups, i.e. normal mice (negative control), P.berghei infected mice without treatment (positive control), and four other groups, i.e. P.berghei infected mice and treated with Artemisin 0.004mg/gBW (A), and combinations of Artemisin 0.004mg/gBW and Moringa leaf extract 0.125mg/gBW (DK1), 0.250mg/gBW (DK2), and 0.500mg/gBW (DK3). On day 3 and 7, blood samples from each group were drawn randomly, parasitemia degree was calculated microscopically (magnification 1000 times), the percentage of CD4+ and CD8+ T cells was determined using flowcytometry. The results of this study indicated that the administration of Artemisin and Moringa leaf extract combination for 7 days significant increased the percentage of CD4 + T cells in DK2 (p=0.001) and DK3 (p=0.000), and decreased the degree of parasitemia in DK1 (p=0.000), DK2 (p=0.000), and DK3 (p=0.000), however CD8 + T cells show no difference. There was a relationship between Artemisin and Moringa leaf extract combination with the degree of parasitemia (p=0.000) and the percentage of CD4+ T cells (p = 0.000), but not on CD8+ T cells. Keywords: parasitemia, CD4+ and CD8+ T cells, Moringa oleifera

Abstract

Malaria infection during pregnancy can cause accumulation of infected-red blood cells in placental intervillous space and induces placental tissue inflammation and hypoxia. This condition triggers endoglin expression, and release of soluble endoglin which can interfere TGF-β binding to its receptor. The aim of this study was to investigate the correlation between placental endoglin expression and TGF-β level with low fetal weight (LFW) in malaria-infected mice. Nine pregnant mice infected with Plasmodium berghei on the day 9th post mating (malaria infected group) and eight normal pregnant mice (non-infected group) were used in this study. The mice were sacrificed on the day 18th post mating, and all fetal body weights were measured by analytical scale. Enzyme Link Immunosorbent Assay (ELISA) was done to determine the level of placental TGF-β while immunohistochemical staining was performed to examine endoglin expression in placental tissue. The mean of fetal body weights of malaria infected group was significantly lower than non-infected group (p=0,002), while the expression of placental endoglin in malaria infected group was significantly higher than non-infected group (p=0.003). The level of placental TGF-β in malaria infected group was also higher than non-infected group but the difference was not significant (p=0.064). Pearson correlation test showed that there were significant negative correlations between fetal body weights with the level of placental TGF-β (p=0.017, r=-0.568) and the expression of placental endoglin (p=0.002, r=-0.694). Malaria infection in pregnant mice will increase both TGF- β and endoglin in placenta tissue and correlate with low fetal weight.

Abstract

Low birth weight is commonly attributed to malaria in pregnancy, but the cellular and molecular mechanisms that underlie this poor birth outcome are incompletely understood. A universally described histopathological feature of placental malaria is excessive deposition of fibrin, the end-product of the coagulation cascade. This study was conducted to compare fibrin deposit in pregnant mice that infected by Plasmodium berghei (treatment group) to the normal pregnant mice (control group) and its association with fetal weight. This research is in vivo experimental laboratory study that used 18 pregnant Balb/c mice which divided to the control the group (8 mice) and treatment group (9 mice infected by P.berghei). Placentas were staining with Haematoxylin-Eosin (HE) for fibrin deposits examination whereas fetal weight was performed with Mettler analytical balance AE 50. Fetal weight of the treatment group was lower than those of the control group (t test, p=0,002). Fibrin deposits were increased in the treatment group (t test, p=0,005) and influenced weight of fetuses (Spearman r=-0,586, p=0,014). Weights of fetuses are interfered by fibrin deposits during malaria infection.

Abstract

Preeclampsia has major symptoms of hypertension and proteinuria and is a cause of significant maternal and infant mortality in the world. The slow development of preeclampsia research possibility caused by the difficulty in acquiring animal preeclampsia. Many existing animal model have been developed, but most of them are expensive to do. The purpose of this study was to determine the effects of intraperitoneal injection of pregnant patients serum with high TNF-α levels toward sFlt-1 serum concentration and blood pressure of pregnant mice. Pregnant patients serum with high TNF-α levels (>20 pg/mL) was injected intraperitoneally to pregnant mice at gestational age 13 and 14 days. At 18 days of gestation, the blood pressure was measured, then the mice were dissected and the serum was taken to measure serum sFlt-1 concentration using ELISA kit(Bioassay Technology Laboratory, E0611Mo). The results showed there was a significant increase in blood pressure (p = 0.000) and the sFlt-1 levels (p = 0.002) of pregnant mice group that injected by pregnant patient serum with high TNF-α levels compare to control group. From these data it can be concluded that intraperitoneal injection of pregnant patients serum with high TNF-α levels to pregnant mice can increase blood pressure and sFlt-1 serum concentration of mice.
