Spectrum of vibrio species associated with acute diarrhea in North Jakarta, Indonesia.

Vibrio spp was isolated from 1024 (21.2%) of 4820 diarrhea patients admitted to a community hospital in North Jakarta from 1996 through 1998. Vibrio cholerae O1 (49.5%) and V. parahaemolyticus (30.1%) comprised the major species isolated, followed by V. cholerae non-O1 (16.9%), and V. fluvialis (9.4%). In 938 (19.4%) patients, Vibrio was found as single isolate. Multiple infections were detected in 86 (1.8%) patients. A small number of V. furnisii, V. metschnikovii, V. mimicus and V. hollisae were also isolated. No V. cholerae O139 was detected. The majority of patients with Vibrio spp. infections were adults between the ages of 20 to 45 years. No Vibrio spp. was isolated from infants <1 year old in this study. In vitro antibiotic susceptibility testing revealed no antibiotic resistance associated with the 507 V. cholerae O1 isolates tested, except for colistin (100%). These data implicate Vibrio spp. as a major cause of diarrhea in this region.

Increasing patient participation in reproductive health consultations: an evaluation of "Smart Patient" coaching in Indonesia.

Paternalistic models of health care, social distance between patients and providers, and cultural norms discourage patients from playing an active role in health consultations. This study tested whether individual coaching can give family planning patients the confidence and communication skills to talk more openly and more vigorously with providers. Educators met with 384 Indonesian women in clinic waiting rooms and coached them on asking questions, expressing concerns, and seeking clarification. An analysis of audiotaped consultations found that patients who received coaching articulated significantly more questions and concerns than others. Coaching narrowed differentials in active communication by patient type, age, and assertiveness, but it widened differentials by patient education and socioeconomic class. The discontinuation rate at 8 months was lower in the intervention than the control condition, but the difference was only marginally significant.

Siphonols A-E: novel nitric oxide inhibitors from Orthosiphon stamineus of Indonesia.

From the methanolic extract of Orthosiphon stamineus, four novel highly oxygenated isopimarane-type diterpenes named siphonols A-D (1-4) and a novel biogenetically interesting norisopimarane-type diterpene named siphonol E (5) were isolated. The new compounds 1-3 and 5 showed more potent inhibitory effects on the nitric oxide (NO) production in lipopolysaccharide (LPS)-activated macrophage-like J774.1 cells than a positive control N(G)-monomethyl-L-arginine (L-NMMA). Siphonols A-E (1-5) represent the first examples of isopimaranes oxygenated at C-20.

Unintended pregnancy and women's psychological well-being in Indonesia.

Few studies have examined the impact of unintended pregnancy on women in developing countries. This paper examines the impact of unintended pregnancy on Indonesian women's psychological well-being. It is hypothesized that experiencing unintended pregnancy is associated with lower psychological well-being and that use of family planning and small family size are associated with higher levels of psychological well-being. Data are drawn from a 1996 survey of 796 women aged 15-49 from two Indonesian provinces, Lampung and South Sumatra. This article focuses on the 71% of women (n=562) who answered all 41 survey items related to psychological well-being. In cluster analysis, women grouped into three clusters, differentiated by their scores on four scales of well-being established through factor analysis (general negative feelings, satisfaction with relationships, satisfaction with economic/family/personal conditions, and negative feelings regarding domestic issues). Women in cluster 3 were characterized mainly by their high level of psychological well-being. Women in cluster 1 had the lowest level of well-being, and women in cluster 2 were in the middle. Multinomial logistic regression was used to assess jointly the effect of unintended pregnancy, contraceptive use, number of children and other factors on a woman's level of psychological well-being. Unintended pregnancy was associated with lower levels of psychological well-being and contraceptive use was associated with higher levels of psychological well-being, while number of children was not associated with level of well-being. Women who had experienced an unintended pregnancy were less likely to be in the high psychosocial well-being cluster versus both the medium and low clusters. In addition, women using contraception were more likely to be classified in the high than in the low or medium well-being clusters.

Risk factors for transmission of foodborne illness in restaurants and street vendors in Jakarta, Indonesia.

In a previous risk factor study in Jakarta we identified purchasing street food as an independent risk factor for paratyphoid. Eating from restaurants, however, was not associated with disease. To explain these findings we compared 128 street food-vendors with 74 food handlers from restaurants in a cross-sectional study in the same study area. Poor hand-washing hygiene and direct hand contact with foods, male sex and low educational level were independent characteristics of street vendors in a logistic regression analysis. Faecal contamination of drinking water (in 65 % of samples), dishwater (in 91 %) and ice cubes (in 100 %) was frequent. Directly transmittable pathogens including S. typhi (n = 1) and non-typhoidal Salmonella spp. (n = 6) were isolated in faecal samples in 13 (7 %) vendors; the groups did not differ, however, in contamination rates of drinking water and Salmonella isolation rates in stools. Poor hygiene of street vendors compared to restaurant vendors, in combination with faecal carriage of enteric pathogens including S. typhi, may help explain the association found between purchasing street food and foodborne illness, in particular Salmonella infections. Public health interventions to reduce transmission of foodborne illness should focus on general hygienic measures in street food trade, i.e. hand washing with soap, adequate food-handling hygiene, and frequent renewal of dishwater.

Helicobacter pylori infection and typhoid fever in Jakarta, Indonesia.

We evaluated the association between typhoid fever and Helicobacter pylori infection, as the latter microorganism may influence gastric acid secretion and consequently increase susceptibility to Salmonella typhi infection. Anti-H. pylori IgG and IgA antibody titres (ELISA) and gastrin concentration (RIA) were determined in the plasma of 87 blood culture-confirmed typhoid fever cases (collected after clinical recovery) and 232 random healthy controls without a history of typhoid fever, in the Jatinegara district, Jakarta. Patients with typhoid fever more often than controls were seropositive for H. pylori IgG (67% vs. 50%, P<0.008), when antibody titres were dichotomized around median titres observed in controls. H. pylori IgA seropositivity was not associated with typhoid fever. Plasma gastrin concentrations indicative of hypochlorhydria (i.e. gastrin > or =25 or > or =100 ng/l) were not significantly elevated in typhoid fever cases compared to controls (P=0.54 and P=0.27 respectively). In a multivariate analysis, typhoid fever was independently associated with young age (<33 years, median age of the controls) [odds ratio (OR) 7.93, 95% confidence interval (CI) 3.90-16.10], and H. pylori IgG seropositivity (OR 1.93, 95% CI 1.10-3.40). Typhoid fever was independently associated with H. pylori IgG seropositivity, but not with elevated gastrin concentration. Therefore, the association suggests a common risk of environmental exposure to both bacteria, e.g. poor hygiene, rather than a causal relationship via reduced gastric acid production.

The occurrence of Trypanosoma evansi in buffaloes in Indonesia, estimated using various diagnostic tests.

The prevalence and incidence of Trypanosoma evansi infections in village buffaloes in Central Java were estimated using parasitological tests, two antigen-detection ELISAs (2G6 Ag-ELISA and Tr7 Ag-ELISA), an antibody-detection ELISA (IgG ELISA) and a card agglutination test (CATT). Of 2387 village buffaloes tested in five districts, 4 % (95 % confidence interval [CI]: 3 %, 5 %) were positive with the microhaematocrit test (MHCT), 58 % (95 % CI: 56 %, 60 %) were positive with the 2G6 Ag-ELISA and 70 % (95 % CI: 68 %, 72 %) were positive with the Tr7 Ag-ELISA. An increasing prevalence with age was found and the proportion of positive buffaloes was highest in the over 84 months-old age-group (68 %) with the 2G6 Ag-ELISA and in the 37-60 months-old age-group (78 %) with the Tr7 Ag-ELISA. Parasitaemic buffaloes were found in more than half of the villages visited. Corrected village-specific prevalence values obtained with the two Ag-ELISAs ranged from 0% to over 100%, and prevalence differed significantly (P < or = 0.0001) between villages in four of the five districts. Overall, 10% of buffaloes tested in markets were found to be parasitaemic and 39, 56 and 47 % were found positive with the 2G6 Ag-ELISA, IgG ELISA and CATT, respectively. Incidence rates varied according to the test used and ranged from 0.22 (95 % CI: 0.09, 0.44) to 0.44 (95 % CI: 0.24, 0.76), per animal-year at risk, in two villages. The results highlight the importance of using validated diagnostic tests to obtain accurate estimates of prevalence and incidence. These parameters are needed, for example in mathematical models, for the development and evaluation of different control strategies for T. evansi infections in buffaloes.

Nitric oxide inhibitory isopimarane-type diterpenes from Orthosiphon stamineus of Indonesia.

A methanolic extract of Orthosiphon stamineus yielded six new highly oxygenated isopimarane-type diterpenes, orthosiphols U-Z (1-6), and 15 previously reported diterpenes. The isolated diterpenes all showed significant dose-dependent inhibitory effects on the nitric oxide (NO) production in lipopolysaccharide (LPS)-activated macrophage-like J774.1 cells. Orthosiphols A (7), B (8), D (9), and X (4) showed more potent inhibitory activities than a positive control, N(G)-monomethyl-l-arginine (l-NMMA), and 1 displayed the strongest activity with an IC(50) value of 6.4 microM.

Cassane- and norcassane-type diterpenes from Caesalpinia crista of Indonesia and their antimalarial activity against the growth of Plasmodium falciparum.

The CH2Cl2 extract of the seed kernels of Caesalpinia crista, which exhibited promising antimalarial activity against Plasmodium berghei-infected mice in vivo, was examined and resulted in the isolation of seven new furanocassane-type diterpenes [caesalpinins C-G (1-5) and norcaesalpinins D and E (6, 7)] together with norcaesalpinins A-C (8-10) and 11 known compounds (norcaesalpinins A-C, 2-acetoxy-3-deacetoxycaesaldekarin e, caesalmin B, caesaldekarin e, caesalpin F, 14(17)-dehydrocaesalpin F, 2-acetoxycaesaldekarin e, 7-acetoxybonducellpin C, and caesalmin G). Their structures were determined on the basis of spectroscopic analysis. The isolated diterpenes showed significant dose-dependent inhibitory effects on Plasmodium falciparum FCR-3/A2 growth in vitro. Their IC50 values ranged from 90 nM to 6.5 microM, and norcaesalpinin E (7) showed the most potent inhibitory activity (IC50, 90 nM).
