We conducted a field survey of glucose-6-phosphate dehydrogenese (G6PD) deficiency in the eastern Indonesian islands, and analyzed G6PD variants molecularly. The incidence of G6PD deficiency in 5 ethnic groups (Manggarai, Bajawa, Nage-Keo, Larantuka, and Palue) on the Flores and Palue Islands was lower than that of another native group, Sikka, or a nonnative group, Riung. Molecular analysis of G6PD variants indicated that 19 cases in Sikka had a frequency distribution of G6PD variants similar to those in our previous studies, while 8 cases in Riung had a different frequency distribution of G6PD variants. On the other hand, from field surveys in another 8 ethnic groups (Timorese, Sumbanese, Savunese, Kendari, Buton, Muna, Minahasa, and Sangirese) on the islands of West Timor, Sumba, Sulawesi, Muna and Bangka, a total of 49 deficient cases were detected. Thirty-nine of these 49 cases had G6PD Vanua Lava (383T>C) of Melanesian origin. In our previous studies, many cases of G6PD Vanua Lava were found on other eastern Indonesian islands. Taken together, these findings may indicate that G6PD Vanua Lava is the most common variant in eastern Indonesian populations, except for Sikka. 相似文献

Infection with Toxoplasma gondii is of medical importance in relation to a recent increase in cases of acquired immunodeficiency syndrome (AIDS). In the present study, we surveyed antibody to Toxoplasma among 1,761 people in Surabaya, Indonesia. The overall prevalence was 58% with significant differences between males (63%) and females (52%; P < 0.001). Although antibody prevalences at 0-9 years in both genders were less than 10%, those at ages over 10 years were more than 50% in males or more than 40% in females, suggesting an extremely high transmission rate of the parasite to humans in this area. A bimodal pattern in the frequency distribution of Toxoplasma antibody levels suggested a persistent feature of Toxoplasma infection in humans. 相似文献

In vitro growth of Plasmodium falciparum is restricted in glucose-6-phosphate dehydrogenase (G6PD)-deficient erythrocytes (RBC), as a result of oxidative stress. Bathocuproine disulphonate (BCS), a copper chelator, as well as cysteine have been shown to synergistically stimulate the in vitro growth of various mammalian cells and Trypanosoma under oxygenated conditions. We examined the effects of these two chemicals on the in vitro growth of P. falciparum in G6PD-deficient RBC, and found that addition of BCS and cysteine synergistically enhanced the growth of the P. falciparum FCR-3 strain in these RBC to the same level as in normal RBC. However, BCS or cysteine alone had no stimulatory effect. To explain this synergistic enhancement, changes in thiol, NADPH and glutathione contents were investigated. After addition of cysteine alone, thiol content in the medium decreased rapidly, but when BCS was added, it was maintained at about 35% at 24 hours after incubation, suggesting that BCS stimulates parasite growth in G6PD-deficient RBC by inhibiting copper-mediated oxidation of cysteine in the medium. In these RBC, no increase in NADPH level, but a slight increase in glutathione, was observed in the presence of both BCS and cysteine. The slight increase of glutathione, was probably due to incorporation of cysteine from the medium, although this could not fully explain the synergistic growth enhancement. These findings taken together suggest that cysteine incorporated into G6PD-deficient RBC may help maintain the thiol groups in many proteins, such as membrane proteins, hemoglobin and enzymes, and plays an important role in maintaining an appropriate culture state necessary for parasite growth. We also examined the effects of BCS and cysteine on adaptation of wild isolates of P. falciparum to in vitro cultivation using the candle jar method. Although there was no drastic effect on growth enhancement, the presence of BCS and cysteine accelerated the appearance of schizonts in many isolates. 相似文献

Medical and entomological surveys were conducted to determine the risk factors of Plasmodium falciparum and P. vivax infections on Lombok Island, Indonesia, to find the risk factors and the main mosquito vectors for each malaria. Multivariate longitudinal analysis demonstrated two significant risk factors for infection with P. falciparum: disappearance of P. vivax parasitemia (p<0.001) and a specific study site (p<0.001). In contrast, younger age (p=0.024) and the interpolated virtual density of An. subpictus (p=0.041) were significantly associated with increased risk of infection with P. vivax. Thus, it seems that the distribution of P. vivax was determined largely by the presence of An. subpictus, whilst that of P. falciparum was influenced by antagonism with P. vivax. This result shows the importance of following-up treated P. vivax patients to identify recrudescence of P. falciparum in this area. 相似文献

Objective: To analyze risk factors, obstetric outcome and the need for mechanical ventilation in preeclampsia complicated by pulmonary edema.Materials and methods: Case–control study using medical record on preeclampsia complicated by pulmonary edema patients in East Java tertiary referral hospital over 2?years. A simple scoring system was developed to predict the need for mechanical ventilation, using logistic regression.Results: 1106 cases of preeclampsia were admitted, with 62 cases (5.6%) had pulmonary edema. Postpartum (p?.001) and cesarean delivery (p?=?.001) proportions were higher in the preeclampsia with pulmonary edema group. Of the 62 cases with pulmonary edema, 81% required intensive care admission and 60% needed mechanical ventilation support. Mechanical ventilation used was associated with eclampsia (p?=?.04), hypertensive crisis (p?=?.02), lower serum albumin (p?=?.05) and higher creatinine (p?=?.01). A simple scoring model developed could predict a 46%–99% probability of need for mechanical ventilation (AUC (ROC): 0.856, 95%CI 0.763–0.95).Conclusions: Pulmonary edema is a common complication of preeclampsia in Indonesian referral hospitals. This severe complication increased maternal and perinatal morbidity and mortality. The developed scoring model in this study can be used as a triage tool to predict the probability of mechanical ventilation use due to this complication. 相似文献

The cooperative malaria control project between Indonesian and Japanese institutions was conducted from 2001 to 2004 at small malaria endemic foci on Lombok and Sumbawa Islands. The aim of this research was to evaluate the effects of the project according to the opinions of the villagers. We conducted a KAP survey of a simple random sample of 300 householders on each island. The conclusion of the study was that the project reduced malaria incidence significantly on Lombok. However, the effects were not as clear on Sumbawa. Poor socio-economic status and lack of school education were important related factors. Therefore, health education, or behavioral change communication, was an essential component of malaria control. 相似文献
