Quality of Life of Cancer Patients during Chemotherapy in Indonesia: A Comparison of EORTC QLQ-C30 and EQ-5D-5L, Based on Patients' Characteristics.

One of the important outcomes to define the success of cancer treatment is the health-related quality of life (HRQoL) that can be measured using generic and/or specific instruments. Our study aims to define the cancer patients' HRQoL in some hospitals in Indonesia as measured by the European Organization for Research and Treatment for Cancer (EORTC QLQ-C30) and the EQ-5D-5L, to define the differences of cancer patients' HRQoL referring to patients' characteristics, and to explore determinants of cancer patients' HRQoL. We recruited 451 cancer patients using a cross-sectional design in two referral hospitals in Central Java, Indonesia, using the purposive sampling technique. All subjects, recruited from July 2020 to October 2021, met the inclusion criteria, namely, adult patients diagnosed with cancers in all stages who willingly participated in the study. The Indonesian value set was used to obtain the EQ-5D-5L index score. We further analyzed the data based on cancer stages and compared two questionnaires using independent t test. We highlighted that most of the cancer patients are female (69.4%), young (86%), and at advanced stages of cancer (54.1%). The physical and role functions and global health status of the cancer patients are poor, and the most severe symptom is fatigue. Moreover, most of them experience severe pain and perform daily activities with difficulties. Some patients' characteristics show significant influences on the HRQoL domains in both questionnaires (p < 0.05). Interestingly, both of the questionnaires have shown significant correlations between similar domains and revealed the poor HRQoL of advanced cancer patients (p < 0.05). Our study finds that cancer patients still have poor HRQoL in some domains. We suggest to the health providers that they apply education and psychological intervention to increase their HRQoL.

Investigating the Relationship between Knowledge and Hepatotoxic Effects with Medication Adherence of TB Patients in Banyumas Regency, Indonesia.

Tuberculosis (TB) still remains the burden in Indonesia. One of the factors that may influence the treatment success of TB is patient's adherence. However, the hepatotoxicity of the TB medicine may decrease the patient's adherence. Our study's aim is to investigate the relationship between the patient's knowledge and the hepatotoxicity with medication adherence of TB patients in Banyumas Regency. This study was conducted at one Community Lung Health Center and two hospitals in Banyumas Regency, Purwokerto, Center of Java, Indonesia. The respondents were 91 TB patients with hepatotoxicity characterized by an increased aspartate transaminase (AST) and alanine aminotransferase (ALT). The level of the patients' knowledge about the hepatotoxicity effect was determined using a questionnaire. The patients' adherence was determined using the Medication Adherence Rating Scale -5 (MARS) questionnaire and pill count methods. Most of the patients were male (53.8%), the age was in the range of 18-29 years old (3.5%), they have no smoking history (59.3%), and their last education majorly was senior high school (46.2%). Most TB patients had poor knowledge (47.3%) and the hepatotoxic effect often appeared in grade 1 (61.5%). The TB patients with a good and moderate level of knowledge were 17.6% and 35.2%, respectively. The TB patients with moderate and severe hepatotoxicity were 39.4% and 1.1%, respectively. The measurement of the level of respondents' adherence using MARS-5 showed that 51.6% of patients had good adherence. We determined the rest of the drug-using pill count method, which resulted in 62.6% of patients adhering to taking antituberculosis drugs. TB patients with a sufficient knowledge and those with mild hepatotoxicity show the higher adherence (p < 0.001). There is a significant relationship between a high level of the patient's knowledge about hepatotoxicity effect, less severity of the hepatotoxic effect, and increased patient adherence in taking the medication.

Modifiable Factors Associated with Non-adherence to Antihypertensive or Antihyperlipidemic Drugs Are Dissimilar: a Multicenter Study Among Patients with Diabetes in Indonesia.

BACKGROUND: To develop targeted and tailored interventions for addressing medication non-adherence, it is important to identify underlying factors. OBJECTIVE: To identify factors associated with non-adherence as well as subtypes of non-adherence to antihypertensive or antihyperlipidemic drugs among patients with type 2 diabetes in Indonesia. DESIGN: An observational multicenter cross-sectional survey. PARTICIPANTS: Patients with type 2 diabetes using either antihypertensive or antihyperlipidemic drugs in four regions in Indonesia. MAIN MEASURES: Non-adherence and its subtypes of intentional and unintentional non-adherence were assessed using the Medication Adherence Report Scale. Necessity and concern beliefs were assessed with the Beliefs about Medicines Questionnaire. We applied binary and multinomial logistic regression to assess associations of medication beliefs, sociodemographic factors, and clinical-related factors to non-adherence and report odds ratios (OR) with 95% confidence intervals (CI). KEY RESULTS: Of 571 participating patients (response rate 97%), 45.5% and 52.7% were non-adherent to antihypertensive and antihyperlipidemic drugs, respectively. Older age was associated with non-adherence to antihypertensive drugs (60-69 years) (OR, 5.65; 95% CI, 2.68-11.92), while higher necessity beliefs (OR, 0.92; 95% CI, 0.88-0.95) were associated with less non-adherence. Factors associated with non-adherence to antihyperlipidemic drugs were female gender (OR, 1.84; 95% CI, 1.03-3.27) and higher concern beliefs (OR, 1.10; 95% CI, 1.03-1.18), while higher necessity beliefs (OR, 0.89; 95% CI, 0.83-0.96) were associated with less non-adherence. CONCLUSIONS: The main factors associated with non-adherence to antihypertensive and antihyperlipidemic drugs are modifiable. In general, beliefs about the necessity of the drug are important but for antihyperlipidemic drugs concerns are important as well. Healthcare providers should pay attention to identify and address medication beliefs during patient counselling.

Quality Assessment of Dried Blood Spots from Patients With Tuberculosis from 4 Countries.

BACKGROUND: Dried blood spot (DBS) sampling is a blood collection tool that uses a finger prick to obtain a blood drop on a DBS card. It can be used for therapeutic drug monitoring, a method that uses blood drug concentrations to optimize individual treatment. DBS sampling is believed to be a simpler way of blood collection compared with venous sampling. The aim of this study was to evaluate the quality of DBSs from patients with tuberculosis all around the world based on quality indicators in a structured assessment procedure. METHODS: Total 464 DBS cards were obtained from 4 countries: Bangladesh, Belarus, Indonesia, and Paraguay. The quality of the DBS cards was assessed using a checklist consisting of 19 questions divided into 4 categories: the integrity of the DBS materials, appropriate drying time, blood volume, and blood spot collection. RESULTS: After examination, 859 of 1856 (46%) blood spots did not comply with present quality criteria. In 625 cases (34%), this was due to incorrect blood spot collection. The DBS cards from Bangladesh, Indonesia, and Paraguay seemed to be affected by air humidity, causing the blood spots not to dry appropriately. CONCLUSIONS: New tools to help obtain blood spots of sufficient quality are necessary and environmental specific recommendations to determine plasma concentration correctly. In addition, 3% of the DBS cards were rejected because the integrity of the materials suggesting that the quality of plastic ziplock bags currently used to protect the DBS cards against contamination and humidity may not be sufficient.

The role of illness perceptions on medication nonadherence among patients with hypertension: A multicenter study in indonesia.

Introduction: Nonadherence to antihypertensive medications is recognized as a significant cause of treatment failure. Therefore, identifying its underlying factors, particularly from the patient's perspective, is essential for developing tailored intervention strategies. The objective of this study was to evaluate the associations between different domains of illness perception and medication nonadherence among patients with hypertension in Indonesia. Patients and methods: A multicenter cross-sectional study was conducted among patients with hypertension aged 18 years old and older who were using antihypertensive medications in the last 3 months in the community health centers in the three cities in Indonesia. The different domains of illness perception (e.g., consequences, timeline, personal control, treatment control, identity, concerns, comprehension, and emotional response) and medication nonadherence were assessed using a validated Brief Illness Perceptions Questionnaire (BIPQ) and Medication Adherence Report Scale (MARS), respectively. A logistic regression analysis was conducted to evaluate the associations between the different domains of illness perception and medication nonadherence adjusting for confounders. The odds ratios (ORs) and 95% confidence intervals (CIs) were reported. Results: A total of 440 participants were included, whom 41.8% reported nonadherence to antihypertensive medications. The majority of the participants were females (64.3%) and aged between 60 and 69 years old (39.5%). The treatment control (OR: 0.80, 95% confidence interval: 0.7-10.90), patient's comprehension of hypertension (OR: 0.89, 95% CI: 0.820-0.97), and patient's emotions (OR: 0.93, 95% CI: 0.88-0.99) were significantly associated with medication nonadherence. No significant associations were observed between the other domains of illness perception and medication nonadherence. Conclusion: Different dimensions of illness perception were associated with non-adherence to antihypertensive medications. Educational interventions should be developed based on patients' perception of their illness.

Association of ABCB1, 5-HT3B receptor and CYP2D6 genetic polymorphisms with ondansetron and metoclopramide antiemetic response in Indonesian cancer patients treated with highly emetogenic chemotherapy.

OBJECTIVE: Suboptimal treatment of chemotherapy-induced nausea and vomiting and unsatisfactory response to antiemetic drugs cause impairment of cancer patient's daily functioning. This study was aimed to investigate the association of selected germline polymorphisms with ondansetron and metoclopramide response in Indonesian cancer patients treated with highly emetogenic chemotherapy. METHODS: We enrolled 202 chemotherapy naïve patients treated with cisplatin at a dosage of ≥50 mg/m(2) as monotherapy or as combined chemotherapy. Ondansetron 8 mg and dexamethasone 8 mg intravenously were the standard antiemetic therapy for prevention of acute chemotherapy-induced nausea and vomiting. Metoclopramide 10 mg orally, three times per day as fixed prescription, was given until 5 days after chemotherapy to prevent delayed chemotherapy-induced nausea and vomiting. Primary and secondary outcomes were the occurrence of chemotherapy-induced nausea and vomiting in the acute and delayed phase. The following single-nucleotide polymorphisms were determined in ABCB1: rs1045642, rs2032582 and rs1128503; in 5-HT3B-R: rs45460698, rs4938058 and rs7943062; and in CYP2D6: rs16947 (CYP2D6 2), rs3892097 (CYP2D6 4) and rs1065852 (CYP2D6 10) using Taqman assays. RESULTS: During the acute phase, 21.8 and 30.2% patients experienced Grade 3 and 4 nausea and vomiting, respectively, whereas 38.6% patients experienced nausea and/or vomiting in the delayed phase. Carriers of the CTG haplotype of the ABCB1 gene experienced Grade 3 and 4 chemotherapy-induced nausea and vomiting more often than other haplotypes in the delayed phase (P< 0.05). No associations were found with the 5-HT3B receptor haplotypes and CYP2D6-predicted phenotypes. CONCLUSIONS: Our study shows that in Indonesian cancer patients treated with highly cytostatic emetogenic, carriership of the CTG haplotype of the ABCB1 gene is related to an increased risk of delayed chemotherapy-induced nausea and vomiting.

Emotional Distress is Associated with Lower Health-Related Quality of Life Among Patients with Diabetes Using Antihypertensive and/or Antihyperlipidemic Medications: A Multicenter Study in Indonesia.

OBJECTIVE: To evaluate the associations between different types of diabetes distress and health-related quality of life (HRQOL) among patients with type 2 diabetes (T2DM) using antihypertensive and/or antihyperlipidemic medications in Indonesia and to explore the differences between those using only antihypertensive, only antihyperlipidemic, or both medications. METHODS: A multicenter cross-sectional study was conducted in Community Health Centers in three cities in Indonesia among patients with T2DM aged at least 18 years who were using antihypertensive and/or antihyperlipidemic medications. Diabetes distress subscales (emotional, regimen-related, interpersonal, and physician-related distress) and HRQOL were assessed using a validated diabetes distress scale-17 and EQ-5D-5L scale, respectively. Multiple linear regression models were used to evaluate the associations between different types of diabetes distress and HRQOL adjusting for confounders. RESULTS: Most of the 503 participants were females (67.6%) and aged 60-69 years (40.8%). Emotional distress was negatively associated with HRQOL among the whole group of patients (ß: -0.08; 95% confidence interval (CI): -0.10, -0.05; p < 0.001). This association was similar across all therapeutic subgroups. Regimen-related distress (ß: -0.06; 95% CI: -0.09, -0.03; p < 0.001) and interpersonal distress (ß: -0.02; 95% CI: -0.05, -0.01; p = 0.022) were negatively associated, whereas physician-related distress (ß: 0.04; 95% CI: 0.01, 0.07; p = 0.037) was positively associated with HRQOL among the whole group. These associations were also observed among those using only antihypertensive medication. CONCLUSION: Emotional distress affects HRQOL in T2DM patients treated for cardiovascular comorbidities, independent of antihypertensive and/or antihyperlipidemic medication use.

Health literacy of people living with HIV in a rural area in Indonesia: A cross-sectional study.

Indonesia, the fourth most populated country in the world, has experienced a fivefold increase in Human Immunodeficiency Virus (HIV)-infected individuals since 2001. Little is known about health literacy in people living with HIV (PLHIV) in Indonesia. This study aimed to determine the level of health literacy among PLHIV in Indonesia and assess associations between sociodemographic variables, beliefs about medicines, stigma and health literacy. We conducted a cross-sectional study using questionnaires in PLHIV in Papua, Indonesia. The short version of the Test of Functional Health Literacy in Adults (S-TOFHLA), Beliefs about Medicines Questionnaire (BMQ) and HIV stigma scale as well as questions on demographic information were completed by the participants from two hospitals in Papua, Indonesia. In a multivariate logistic regression analysis, we assessed the association between sociodemographic variables, stigma, beliefs about medicine and low health literacy. Overall, 331 participants were included, 62.0% female, 67.0% Papuans. A total of 38.5% of participants had low health literacy. PLHIV with multi-dose regimen were less likely to have low health literacy than those taking a fixed-dose combination (OR = 0.51; 95%CI = 0.32-0.82). PLHIV who had social support in medicine-taking were more likely to have low health literacy (OR = 1.78; 95%CI = 1.07-2.97). More awareness about medication overuse (OR = 1.17; 95%CI = 1.06-1.29) and medication harm (OR = 1.10; 95%CI = 1.01-1.20) were also associated with having low health literacy. Overall, interventions targeting health literacy may be a promising strategy to improve self-management.

Knowledge of Antiretroviral Treatment and Associated Factors in HIV-Infected Patients.

This study aimed to assess the knowledge of antiretroviral (ARV) treatment and the associated factors in HIV-infected patients in Vietnam. We conducted a cross-sectional descriptive study of 350 human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients being treated with ARV at outpatient clinics at Soc Trang, Vietnam, from June 2019 to December 2019. Using an interview questionnaire, patients who answered at least eight out of nine questions correctly, including some required questions, were considered to have a general knowledge of ARV treatment. Using multivariate logistic regression to identify factors associated with knowledge of ARV treatment, we found that 62% of HIV-infected patients had a general knowledge of ARV treatment, with a mean score of 8.2 (SD 1.4) out of 9 correct. A higher education level (p < 0.001); working away from home (p = 0.013); getting HIV transmitted by injecting drugs or from mother-to-child contact (p = 0.023); the presence of tension, anxiety, or stress (p = 0.005); self-reminding to take medication (p = 0.024); and a high self-evaluated adherence (p < 0.001) were found to be significantly associated with an adequate knowledge of ARV treatment. In conclusion, education programs for patients, as well as the quality of medical services and support, should be strengthened.

Health Workers' Perceptions and Expectations of the Role of the Pharmacist in Emergency Units: A Qualitative Study in Kupang, Indonesia.

Background. An essential way to ensure patient safety in the hospital is by applying pharmacy services in emergency units. This strategy was implemented in Indonesia several years ago, with the aim of ensuring that adequate pharmacy services are given to patients in hospitals. To achieve this, pharmacists are required to cooperate with other health workers via inter-professional teamwork. This study intended to identify the perceptions and expectations of health workers with respect to pharmacy services in emergency units. Methods. This was a qualitative study, using a phenomenological approach with a semi-structured interview technique to obtain data. This study was performed at the Prof. Dr. W.Z. Johannes Hospital Kupang from June to September 2018. The results of the interviews were thematically analyzed using QSR NVivo software 11. Results. The themes identified in this study included: (1) The positive impact of pharmacists in service; (2) Badan Penyelenggara Jaminan Sosial (BPJS) influence; (3) Acceptance of health workers; (4) Medication administration information; and (5) Expectations of health workers. Various perceptions were conveyed by participants regarding the emergency unit services in the hospital's pharmaceutical department. Data obtained proved that the existence of a pharmacist increased the efficiency of time for services and prevented human error. Conclusion. Pharmacists and policy-makers play a significant role in providing appropriate pharmaceutical services in emergency units. Pharmacists also need to improve their quality of practice in accordance with their competence. They must review the patient medical history and physician's prescriptions, educate the patients and other health workers, so that the workload and service time will be reduced.

Economic Evaluations of Dengue Vaccination in the Southeast Asia Region: Evidence From a Systematic Review.

OBJECTIVES: To review the literature on the cost-effectiveness of dengue vaccination in Southeast Asian countries and possibly to provide recommendations on promoting dengue vaccination in this region. METHODS: A systematic search was conducted to identify relevant articles in 3 major databases (ProQuest, American Society of Tropical Medicine and Hygiene, and PubMed). Complete economic evaluation studies, including willingness-to-pay (WTP) studies, that were conducted in any Southeast Asian country were included in this study. Systematic review, non-full-text, and non-English studies were specifically excluded. RESULTS: Nine selected studies highlighted the economic evaluation of dengue vaccination in Southeast Asian countries by considering many parameters (eg, vaccine cost, vaccine efficacy, cost-effectiveness threshold, economic assessment, public acceptance, and WTP). All studies confirmed that dengue vaccine can be used as a prevention strategy to reduce the incidence rate of dengue cases by providing a variance of high cost-effectiveness values. In addition, communities provided a good assessment, acceptance, and WTP value for the vaccine. CONCLUSIONS: The use of dengue vaccine could reduce the burden of disease and economic burden due to dengue infection in Southeast Asian countries. The efficacy of dengue vaccine was estimated to be 50-95% for those <9 years, 9 years, and >9 years. In particular, several studies reported that dengue vaccine could be categorized as a cost-effective intervention in Southeast Asian countries within certain conditions.

Effect of Atypical Antipsychotic on Blood Pressure in Inpatients with Schizophrenia of Prof. Dr. Soerojo Mental Health Hospital Magelang.

CONTEXT: Schizophrenia ranks the top of all mental disorders with poor prognosis. Central Java Province is in the top five of schizophrenia incidents in Indonesia. Antipsychotic is the main therapy for schizophrenia, which is divided into 2, atypical and typical. The atypical antipsychotic is more preferable because of the minimal effect of the extrapyramidal syndrome but affects the blood pressure. AIMS: To analyze the blood pressure of schizophrenia inpatients during the pre and post-use of atypical antipsychotics in RSJ Prof. Dr. Soerojo Magelang. SETTINGS AND DESIGN: This study was an observational study with cohort retrospective methods. METHODS AND MATERIAL: The research was approved and reviewed by the committee of ethics and law of Prof. Dr. Soerojo Mental Hospital. The inclusion criteria are those diagnosed with schizophrenia based on Diagnostic and Statistical Manual of Mental Disorders-IV (DSM IV), aged about 17-55 years old, receiving antipsychotic atypical therapy for at least 3 months.The exclusion criteria are inpatients who also receive antidepressants and antihypertension, have a history of cardiovascular disease and hypertension, and incomplete medical records. STATISTICAL ANALYSIS USED: Wilcoxon, Mann-Whitney, and Kruskal-Wallis test. RESULTS: The result of this study most of them were treated using combination risperidone and clozapine (82.1%). In this study, 43 inpatients experienced a decrease in systolic blood pressure, 57 in systolic blood pressure, 6 with no change in systolic blood pressure, 47 a decrease in diastolic blood pressure, 50 an increase in diastolic blood pressure, and 9 with no change in diastolic blood pressure. CONCLUSIONS: There was no significant difference in the blood pressure before and after the treatment.

Cost of Illness Study of Patients with Dengue Hemorrhagic Fever at One of the Private Hospitals in Yogyakarta.

Dengue hemorrhagic fever (DHF) caused by the dengue virus is one of the high-prevalence diseases in tropical countries, such as Indonesia. It has been highlighted that high-prevalence diseases are strongly correlated with high-treatment costs. In particular, Yogyakarta has been reported as one of the provinces with a high prevalence of DHF. This study aimed to estimate the cost of illness because of DHF and to analyze the correlation between the use of drugs with its cost and length of stay, with total hospital administrative cost at one of the private hospitals in Yogyakarta. A cross-sectional study was applied in this study by collecting patients' medical record and financial data, such as demographic characteristic, medication, length of stay, and direct medical cost health-care perspective. The numbers of dengue patients were applied in this study by considering 87 patients and 143 patients with DHF in 2015 and 2016, respectively. Indirect medical costs were collected from a questionnaire by 20 respondents. Spearman's statistical test was used in this study to conduct the bivariate test. The average direct medical cost from the perspective of health care in 2015 and 2016 in DHF patients with Badan Penyelenggara Jaminan Sosial (BPJS) insurance and non-BPJS insurance was US$243.6; US$363.41 and US$368.13; US$427.03. The indirect medical costs showed that the highest percentage productivity loss was US$70.98-212.95. Correlation between the numbers of drug with drug cost was significant (P < 0.05) with correlation coefficient (value ρ) of 0.527 and 0.603. Correlation between lengths of stay with the cost of hospitalization was significant (P < 0.05) with correlation coefficient (value ρ) of 0.375 and 0.562. It can be concluded that DHF has a relatively high cost of illness both in direct and indirect costs.

Polymorphism of TPH2 Gene rs120074175 Is Not Associated with Risk Factors of Schizophrenia.

CONTEXT: Polymorphism on tryptophan hydroxylase 2 (TPH2) gene rs120074175 can cause the synthesis of neurotransmitter serotonin in the brain to reduce up to 80%. Reduced serotonin in the brain can cause dopamine release to occur continuously. Excess dopamine in the brain may cause positive symptom of schizophrenia. AIM: The aim of this study was to investigate the genotype distribution of TPH2 rs120074175 gene on patients with schizophrenia at Prof. Dr. Soerojo Magelang Psychiatric Hospital, Indonesia, and the relationship between the genetic polymorphism of the TPH2 rs120074175 gene against risk factors of schizophrenia. SETTINGS AND DESIGN: This was a cross-sectional study. MATERIALS AND METHODS: The method used was amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Whole blood from healthy subjects and patients with schizophrenia, Wizard genomic deoxyribonucleic acid (DNA) purification kit (Promega, Fitchburg, Wisconsin), PCR master mix (Promega), ARMS-PCR primers, ddH2O, agarose (Thermo Scientific, Seoul, South Korea), Tris, Acetic Acid, EDTA (TAE) 1X, ethidium bromide, loading dye 6×, and DNA ladder (Thermo Scientific) were the materials used. STATISTICAL ANALYSIS: Hardy-Weinberg equilibrium and chi-square (χ2) tests were used. RESULTS: The results showed that both groups (healthy subjects and patients with schizophrenia) at the Prof. Dr. Soerojo Magelang Psychiatric Hospital have a wild-type GG genotype (100%) without anyone having a mutant A allele. CONCLUSION: TPH2 rs120074175 gene polymorphism was not associated with risk factors for schizophrenia.

Single-nucleotide Polymorphism of CTLA-4 (rs5742909) in Correlation with Schizophrenia Risk Factor.

BACKGROUND: Cytotoxic T protein lymphocyte antigen-4 (CTLA-4) plays a key role in regulating the T-cell system, where occurrence of disturbances in the system seen by imbalances in Th1 and Th2 levels is believed to be one of the etiologies of schizophrenia. Single-nucleotide polymorphisms (SNPs) at rs5742909 in the CTLA-4 gene (C→T) might affect the expression level of CTLA-4 protein. AIMS AND OBJECTIVES: The aim of this study was to determine the genotype distribution of the CTLA-4 gene (rs5742909) in patients with schizophrenia at Rumah Sakit Jiwa Prof. Dr. Soerojo Magelang and identify the correlation of these genetic polymorphisms as the risk factors of schizophrenia. MATERIALS AND METHODS: This research was conducted through the stage of submitting ethical approval, primer design, chromosomal DNA isolation, optimization of polymerase chain reaction conditions, and data analysis. RESULTS: Based on the results of the study, the CC genotype was shown in 36 patients (78.26%), TT genotype in 10 patients (21.73%), and no TT genotypes. However, statistical analysis using Fisher's exact and binary logistic regression statistical test showed no significant relationship between genetic polymorphism of the CTLA-4 rs5742909 against risk factors for schizophrenia (P = 0.05; α = 5%). CONCLUSION: SNP at rs5742909, C-to-T-allele transition, was not significant associated with the risk of schizophrenia.

Knowledge, Attitudes, and Practices of Lung Cancer Risk Factors in West Bandung Society.

BACKGROUND: Lung cancer is one of the leading causes of morbidity and mortality worldwide, so prevention of lung cancer is necessary. The aim of this study was to measure level of knowledge, attitude, and actions concerning risk factors of lung cancer in West Bandung. MATERIALS AND METHODS: The research was conducted by quantitative study design with a quasi-experimental approach. Measurement of respondents' knowledge, attitudes, and actions was carried out by giving questionnaires of knowledge, attitudes, and actions. Questionnaires were given to respondents before and after providing education about risk factors of lung cancer. Respondents were from 42 societies in Bandung. The data obtained were tested by using comparison and correlation test. RESULTS: The results showed a significant difference between knowledge and attitudes (P = 0.001). Meanwhile, the action did not change significantly (P > 0.05). Correlation test showed that knowledge and attitude had a correlation of P = 0.001 in the pretest and P = 0.23 (P < 0.05) in the posttest. CONCLUSION: This research concludes that the level of knowledge and attitudes toward risk factors of lung cancer has increased.

CYP2E1 polymorphism, acetylator profiles and drug-induced liver injury incidence of Indonesian tuberculosis patients.

OBJECTIVE: A polymorphism of CYP2E1 may be directly associated with the development of INH hepatotoxicity. We conducted this study to evaluate the association between polymorphisms of CYP2E1, Isoniazid (INH) concentration and the acetylator status of INH in cases of Indonesian tuberculosis patients with drug-induced liver disease (DILI). METHODS: We conducted our study with a cohort design consisting of 55 Indonesian adult tuberculosis (TB) patients. Acetylating phenotypes were studied in using the metabolic ratio of plasma AcHZ/HZ. DILI was defined using CTCAV version 4.0. The allelic and genotypic frequency distributions of CYP2E1 rs 3813867 were studied using the polymerase chain reaction - amplification refractory mutation system (ARMS) methodology. RESULTS: Patients with an INH concentration of more than 7µg/mL showed a higher risk of developing DILI when compared with patients who showed a therapeutic range of 3-6µg/mL INH (OR: 1.3, 95% CI: 0.2-8.2). Slow acetylators had a higher incidence of DILI when compared with rapid acetylators (OR: 4.6, 95% CI: 1.3-15.9). Meanwhile, subjects with GC had a higher risk of DILI incidence (OR: 4.3, 95% CI: 0.8-24.4). CONCLUSION: Our study shows that polymorphisms of CYP2E1 and slow acetylator may have role in the DILI incidence.

Differences in 5-hydroxytryptamine-3B haplotype frequencies between Asians and Caucasians.

BACKGROUND: The 5-hydroxytryptamine (5-HT3) receptor is a ligand-operated ion channel with five different receptor subunits (5-HT3A, B, C, D, and E) found in humans. Activation of 5-HT3 receptors influences various effects such as drug-induced emesis and causes behavioral problems such as anxiety, depression and cognitive disorders. To explore interethnic differences in the response to 5-HT3 antagonists, we studied haplotype frequencies in the gene encoding the 5-HT3B receptor in Asians and Caucasians. METHODS: Three single nucleotide polymorphisms (SNPs) of the 5-HT3B receptor gene, i.e., deletion AAG at the 5'-UTR position, 18792A>G at the intron position, and 46698G>A at the 3' near gene position, were selected and genotyped in 165 Indonesian cancer patients and 188 Caucasian healthy volunteers. Haplotypes were set with gPlink, whereas the differences in haplotype frequencies between Indonesians and Caucasians were compared using multivariate analysis. RESULTS: The haplotype profiles based on the deletion AAG, 18792A>G and 46698G>A were AAGAA, AAGAG, AAGGG, and deletion AG in both Indonesians and Caucasians. The frequency of the AAGAG haplotype was 54.8% in Indonesians and 39.9% in Caucasians (p<0.05). The frequency of the AAGGG haplotype was 14.3% in Indonesians and 29.3% in Caucasians. Moreover, there were significant differences in the frequencies of haplotype pairs between Indonesians and Caucasians (p<0.001). CONCLUSION: Indonesian cancer patients had significantly different AAGAG and AAGGG haplotype frequencies of the gene encoding the 5-HT3B receptor compared to healthy Caucasians. This finding could be useful for understanding interethnic differences in the response to drugs targeting the 5-HT3B receptor in cancer-treatment-related emesis.
