Bone health in urban midlife Malaysian women: risk factors and prevention

Lim PS, Ong FB, Adeeb N, Seri SS, Noor-Aini MY, Shamsuddin K, et al.

Osteoporos Int, 2005 Dec;16(12):2069-79.
PMID: 16234999 DOI: 10.1007/s00198-005-2003-4

The aim of this study was to identify risk factors associated with osteoporosis in urban midlife Malaysian women and to assess the effectiveness of lifestyle intervention in bone loss prevention with hormone replacement therapy (HRT) as a positive control. A total of 514 disease-free, uterus-intact, non-HRT-using women aged 45 years and older were recruited into the study. After initial bone mineral density (BMD) assessments, they were randomized into three groups: GI (control), G2 (lifestyle intervention), and G3 (lifestyle intervention with HRT). The study group was composed of 67.5% Chinese, 27.8% Malay, and 4.2% Indians with a mean age of 51.07+/-5.28 years. Two-fifths were postmenopausal, and the prevalence of osteoporosis was 24.1%, seen predominantly at the hip. Postmenopausal women had significantly lower mean BMD and a higher incidence of osteoporosis compared with the premenopausal women, 42.1% vs. 11.1% (p<0.0005). A lower incidence of osteoporosis was found in women who took calcium supplementation regularly as opposed to those who do not, 18.7% vs. 29.3% (p=0.036). Age and a greater postmenopausal duration showed a significant negative association with BMD, whereas higher family income, weight, body mass index, and waist and hip circumference were positively correlated. After 18-20 months, the effect of intervention was assessed based on BMD values of 279 women at baseline and after intervention. Lifestyle intervention alone was effective in premenopausal women, preventing over 90% of spinal bone loss compared with the controls, who lost 11.6% (0.046 g/cm2) bone mass with similar losses of hip bone, 2.0% (0.026 g/cm2) vs. 1.5% (0.020 g/cm2). Premenopausal women on HRT also showed a substantial decrease in spine and hip BMD, 18.6% (0.081 g/cm2) and 9.0% (0.122 g/cm2), respectively. The lifestyle intervention program retarded postmenopausal bone loss by 21% and 37% compared with controls, who lost 9.6% (0.141 g/cm2) and 6.0% (0.138 g/cm2) bone mass at the spine and hip. In comparison, lifestyle intervention with HRT increased postmenopausal BMD by 12.7% (0.216 g/cm2) at the spine and 1.9% (0.042 g/cm2) at the hip. The changes in hip BMD were influenced by current age, ethnicity, and income, while intervention had the strongest effect on spine BMD changes. In conclusion, lifestyle intervention prevented spinal bone loss in premenopausal women and retarded postmenopausal spine and hip bone loss compared with controls. The benefits of physical activity on spine and hip BMD highlight its potential as a safe and cost-effective alternative to HRT, which is not advocated because of its potential adverse effects.

Fulltext The prevalence of functional impairment among elderly aged 60 years and above attending Klinik Kesihatan Batu 9 Ulu Langat, Selangor

Loh KY, Khairani O, Norlaili T

Med J Malaysia, 2005 Jun;60(2):188-93.
PMID: 16114159

The aim of this study was to determine the prevalence of functional impairment and its associated factors among patients aged 60 years and above attending Klinik Kesihatan Batu 9 Ulu Langat, Selangor. This is a cross sectional community health clinic based study. A total of 260 elderly patients attending the community health clinic were interviewed. They were clinically assessed for functional impairment by using the 9 item Instrumental Activities of Daily Living (IADL) scale. There were 118 (45.4%) elderly male and 142 (54.6%) elderly female with age ranging from 60 years to 92 years with the mean age of 67.5 and 65.5 years for male and female respectively. Chinese form the largest population (42.3%) followed by Malay (36.5%), Indian (19.2%) and others (2.0%). The overall prevalence of functional impairment among elderly aged 60 years and above in this study was 33.5%. Among the functionally impaired, two patients (0.8%) were totally dependent. There were significant associations between functional impairment and older age (p = 0.025), lower income group (p = 0.010), lower education level (p = 0.030) and history of chronic medical illness (p = 0.020). Functional impairment had no significant association with ethnic group, gender, occupation and living arrangement. For daily activities that were assessed, the commonest impairment was inability to perform shopping (40%) followed by impairment in climbing up staircase (36.6%) and impairment in taking medication (35%). Advanced age, lower income, lower education and history of medical illness are associated with functional impairment. Functional impairment is an important consideration in caring for the elderly patients in the community. These findings have implications in caring of the elderly in which attention need to be paid to activities such as shopping, climbing stairs and taking medication. The use of the IADL scale is feasible for screening of functional impairment among the elderly population in the community.

Fulltext Do adolescents attending Bandar Mas primary care clinic consult health professionals for their common health problems?

Khairani O, Zaiton S, Faridah MN

Med J Malaysia, 2005 Jun;60(2):134-9.
PMID: 16114152

The aims of the study were to determine the prevalence of the common health problems namely acne, overweight, smoking and depressive symptoms among adolescents attending a primary healthcare clinic, whether they seek treatment for these problems and the reasons for not consulting health professionals. It was a clinic-based, crosssectional study. All adolescents aged 13 to 20 years who attended the clinic during the study period were included in the study. The respondents were given self-administered questionnaires and their weights were measured to assess if they had the above disorders. A total of 215 adolescents were included in the study. The proportion of adolescents who had acne were 70.7%, overweight 8.9%, smoking 41.9% and depressive symptoms 9.8%. Only 25% of those who had acne, 47% of those who were overweight, 9.5% who had depressive symptoms and none of those who smoked had ever sought treatment for these problems. The common reasons given for not consulting the health professionals were 'did not consider it as a problem', 'shy' and 'thought there was no treatment available'. The majority of the adolescents who attended the clinic did not consult health professionals the above common health problems. It is important to educate them on these disorders and encourage health-seeking behaviour in adolescents.

Correlates of Children's Eating Attitude Test scores among primary school children

Shariff ZM, Yasin ZM

Percept Mot Skills, 2005 Apr;100(2):463-72.
PMID: 15974357

A total of 107 Malay primary school girls (8-9 yr. old) completed a set of measurements on eating behavior (ChEAT, food neophobia scales, and dieting experience), the Rosenberg Self-Esteem Scale, body shape satisfaction, dietary intake, weight, and height. About 38% of the girls scored 20 and more on the ChEAT, and 46% of them reported dieting by reducing sugar and sweets (73%), skipping meals (67%), reducing fat foods (60%) and snacks (53%) as the most frequent methods practiced. In general, those girls with higher ChEAT scores tended to have lower self-esteem (r=.39), indicating they were more unwilling to try new foods (food neophobic) (r=.29), chose a smaller figure for desired body size (r=-.25), and were more dissatisfied with their body size (r=.31).

Fathelrahman AI, Ab Rahman AF, Mohd Zain Z

Clin Toxicol (Phila), 2005;43(2):89-94.
PMID: 15822759

Acute poisoning is a significant health problem all over the world. In Malaysia, nationwide data on poisoning pattern is scarce and incomplete. The objectives of our study were to determine the pattern of acute drug and chemical poisoning at Penang General Hospital (PGH), in the northern region of Malaysia, and to compare poisoning characteristics between different ethnic groups. The study was a retrospective case review of all poisoned patients admitted to PGH during the years 2000-2002. We collected data concerning demographic parameters of patients, information about the agent(s) implicated, and circumstances surrounding the event. There were 493 poisoning incidents. Nearly two-thirds of the poisoned cases involved female patients. The predominant mode of poisoning was intentional (51.5%). The age group 15.1-30 years ranked at the top, constituting 55.2% of all cases. Drugs were the predominant agents implicated. Among cases associated with drugs, paracetamol was the main causative agent (44.7%). Chinese patients constituted 37.7% of all poisoning cases, followed by the Indians (31.6%) and Malays (26.6%). Between ethnic groups, Indian patients were found to have the highest rate of poisoning admission of 75.2 per 100,000 persons.

The relationship of hostility, negative affect and ethnicity to cardiovascular responses: an ambulatory study in Singapore

Enkelmann HC, Bishop GD, Tong EM, Diong SM, Why YP, Khader M, et al.

Int J Psychophysiol, 2005 May;56(2):185-97.
PMID: 15804452

This study tested the hypotheses that ambulatory heart rate and blood pressure would be higher for individuals high but not low in hostility when they experienced negative affect or social stress and that this interaction would be stronger for Indians compared with other Singapore ethnic groups. Ambulatory blood pressure monitoring was done on 108 male Singapore patrol officers as they went about their daily duties. After each BP measurement participants completed a computerized questionnaire including items on emotional experience. Individuals high in hostility showed higher systolic blood pressure when reporting negative affect whereas this was not true for those low in hostility. Ethnic differences were obtained such that Indians showed an increase in mean arterial pressure when angered whereas MAP was negatively related to anger for Malays and unrelated for Chinese. Also a three-way interaction between ethnicity, hostility, and social stress indicated that hostility and social stress interacted in their effects on DBP for Indian participants but not for Chinese or Malays. Finally, a three-way interaction was obtained between ethnicity, hostility and negative affect for heart rate in which heart rate increased with increasing levels of negative affect for Chinese high in hostility and Malays low in hostility but decreased with increasing negative affect for all other participants. These data are consistent with higher CHD rates among individuals high in hostility and also provide additional evidence on ethnic differences in cardiovascular reactivity in Singapore.

Prevalence and determinants of excessive daytime sleepiness in an Asian multi-ethnic population

Ng TP, Tan WC

Sleep Med, 2005 Nov;6(6):523-9.
PMID: 16271696

BACKGROUND AND PURPOSE: To investigate the prevalence and determinants of daytime sleepiness in an Asian multi-ethnic population. Cross-sectional survey based on a questionnaire in multi-ethnic Asian adult population of Singapore (2.4 million).
PATIENTS AND METHODS: Measured frequency of excessive daytime sleepiness (EDS), socio-demographic status, sleep duration, perceived sleep insufficiency, frequent awakenings, difficulty falling asleep, snoring, breathing pauses, GHQ-12, shift work, solvent exposure at work, substance use, medications, and chronic diseases in random sample of 2,298 adults, aged 20-74 years, representing Chinese, Malays and Indians.
RESULTS: Among the respondents, 10.8% reported usually feeling sleepy in the daytime, and 9.0% were classified as having EDS. Marked ethnic difference was observed, with higher rates of EDS in Malays and Chinese, compared to Indians. Increased risk of EDS was associated with perceived sleep insufficiency; snoring and breathing pauses; shift work and solvent exposure at work; psychiatric morbidity and chronic diseases, particularly chronic rhinitis; and medications with sedating effects.
CONCLUSIONS: Daytime sleepiness is associated with a multiplicity of highly prevalent risk factors in the community, including sleep behavior, breathing-, work- and medically related factors. Significant ethnic differences, which were not explained by these factors, were observed between Chinese, Malays and Indians.

Ramelah M, Aminuddin A, Alfizah H, Isa MR, Jasmi AY, Tan HJ, et al.

FEMS Immunol. Med. Microbiol., 2005 May 1;44(2):239-42.
PMID: 15866222

Helicobacter pylori infection of a distinct subtype of cagA may lead to different pathological manifestation. The aim of this study is to determine the presence of cagA gene and its variants in H. pylori infection among different ethnic groups and its effect on gastroduodenal diseases. Overall detection of cagA among the 205 clinical isolates of H. pylori was 94%. Variations in size of the 3' region of cagA gene were examined among 192 Malaysian H. pylori cagA-positive strains. Results showed that three cagA variants differing in fragment length of PCR products were detected and designated as type A (621-651bp), type B (732-735bp) and type C (525 bp). Although there was no association between any of the cagA subtypes with peptic ulcer disease (p>0.05), an association between cagA subtypes with a specific ethnic group was observed. Specific-cagA subtype A strains were predominantly isolated from Chinese compared to Malays and Indians (p<0.0005), and cagA subtype B strains were predominantly isolated from Malays and Indians compared to Chinese (p<0.05). The cagA type A strains of H. pylori is commonly found in the Chinese patients who have a higher risk of peptic ulcer disease, thus indicating that it could be used as an important clinical biomarker for a more severe infection.

CYP2D6 Genetic Polymorphisms and Phenotypes in Different Ethnicities of Malaysian Breast Cancer Patients

Chin FW, Chan SC, Abdul Rahman S, Noor Akmal S, Rosli R

Breast J, 2016 Jan-Feb;22(1):54-62.
PMID: 26510986 DOI: 10.1111/tbj.12518

The cytochrome P450, family 2, subfamily D, polypeptide 6 (CYP2D6) is an enzyme that is predominantly involved in the metabolism of tamoxifen. Genetic polymorphisms of the CYP2D6 gene may contribute to inter-individual variability in tamoxifen metabolism, which leads to the differences in clinical response to tamoxifen among breast cancer patients. In Malaysia, the knowledge on CYP2D6 genetic polymorphisms as well as metabolizer status in Malaysian breast cancer patients remains unknown. Hence, this study aimed to comprehensively identify CYP2D6 genetic polymorphisms among 80 Malaysian breast cancer patients. The genetic polymorphisms of all the 9 exons of CYP2D6 gene were identified using high-resolution melting analysis and confirmed by DNA sequencing. Seven CYP2D6 alleles consisting of CYP2D6*1, CYP2D6*2, CYP2D6*4, CYP2D6*10, CYP2D6*39, CYP2D6*49, and CYP2D6*75 were identified in this study. Among these alleles, CYP2D6*10 is the most common allele in both Malaysian Malay (54.8%) and Chinese (71.4%) breast cancer patients, whereas CYP2D6*4 in Malaysian Indian (28.6%) breast cancer patients. In relation to CYP2D6 genotype, CYP2D6*10/*10 is more frequently observed in both Malaysian Malay (28.9%) and Chinese (57.1%) breast cancer patients, whereas CYP2D6*4/*10 is more frequently observed in Malaysian Indian (42.8%) breast cancer patients. In terms of CYP2D6 phenotype, 61.5% of Malaysian Malay breast cancer patients are predicted as extensive metabolizers in which they are most likely to respond well to tamoxifen therapy. However, 57.1% of Chinese as well as Indian breast cancer patients are predicted as intermediate metabolizers and they are less likely to gain optimal benefit from the tamoxifen therapy. This is the first report of CYP2D6 genetic polymorphisms and phenotypes in Malaysian breast cancer patients for different ethnicities. These data may aid clinicians in selecting an optimal drug therapy for Malaysian breast cancer patients, hence improve the clinical outcome of the patients.

Fulltext Validation of the Framingham general cardiovascular risk score in a multiethnic Asian population: a retrospective cohort study

Chia YC, Gray SY, Ching SM, Lim HM, Chinna K

BMJ Open, 2015;5(5):e007324.
PMID: 25991451 DOI: 10.1136/bmjopen-2014-007324

OBJECTIVE: This study aims to examine the validity of the Framingham general cardiovascular disease (CVD) risk chart in a primary care setting.
DESIGN: This is a 10-year retrospective cohort study.
SETTING: A primary care clinic in a teaching hospital in Malaysia.
PARTICIPANTS: 967 patients' records were randomly selected from patients who were attending follow-up in the clinic.
MAIN OUTCOME MEASURES: Baseline demographic data, history of diabetes and smoking, blood pressure (BP), and serum lipids were captured from patient records in 1998. Each patient's Framingham CVD score was computed from these parameters. All atherosclerotic CVD events occurring between 1998 and 2007 were counted.
RESULTS: In 1998, mean age was 57 years with 33.8% men, 6.1% smokers, 43.3% diabetics and 59.7% hypertensive. Median BP was 140/80 mm Hg and total cholesterol 6.0 mmol/L (1.3). The predicted median Framingham general CVD risk score for the study population was 21.5% (IQR 1.2-30.0) while the actual CVD events that occurred in the 10 years was 13.1% (127/967). The median CVD points for men was 30.0, giving them a CVD risk of more than 30%; for women it is 18.5, a CVD risk of 21.5%. Our study found that the Framingham general CVD risk score to have moderate discrimination with an area under the receiver operating characteristic curve (AUC) of 0.63 [c-statistic or c-index]. It also discriminates well for Malay (AUC 0.65, p=0.01), Chinese (AUC 0.60, p=0.03), and Indians (AUC 0.65, p=0.001). There was good calibration with Hosmer-Lemeshow test χ(2)=3.25, p=0.78.
CONCLUSIONS: Taking into account that this cohort of patients were already on treatment, the Framingham General CVD Risk Prediction Score predicts fairly accurately for men and overestimates somewhat for women. In the absence of local risk prediction charts, the Framingham general CVD risk prediction chart is a reasonable alternative for use in a multiethnic group in a primary care setting.

Fulltext Opportunistic mammography screening provides effective detection rates in a limited resource healthcare system

Teh YC, Tan GH, Taib NA, Rahmat K, Westerhout CJ, Fadzli F, et al.

BMC Cancer, 2015;15:405.
PMID: 25972043 DOI: 10.1186/s12885-015-1419-2

Breast cancer is the leading cause of cancer deaths in women world-wide. In low and middle income countries, where there are no population-based mammographic screening programmes, late presentation is common, and because of inadequate access to optimal treatment, survival rates are poor. Mammographic screening is well-studied in high-income countries in western populations, and because it has been shown to reduce breast cancer mortality, it has become part of the healthcare systems in such countries. However the performance of mammographic screening in a developing country is largely unknown. This study aims to evaluate the performance of mammographic screening in Malaysia, a middle income country, and to compare the stage and surgical treatment of screen-detected and symptomatic breast cancer.

Fulltext Child maltreatment experience among primary school children: a large scale survey in Selangor state, Malaysia

Ahmed A, Choo WY, Marret MJ, Guat-Sim C, Othman S, Chinna K

PLoS One, 2015;10(3):e0119449.
PMID: 25786214 DOI: 10.1371/journal.pone.0119449

Official reports of child maltreatment in Malaysia have persistently increased throughout the last decade. However there is a lack of population surveys evaluating the actual burden of child maltreatment, its correlates and its consequences in the country. This cross sectional study employed 2 stage stratified cluster random sampling of public primary schools, to survey 3509 ten to twelve year old school children in Selangor state. It aimed to estimate the prevalence of parental physical and emotional maltreatment, parental neglect and teacher- inflicted physical maltreatment. It further aimed to examine the associations between child maltreatment and important socio-demographic factors; family functioning and symptoms of depression among children. Logistic regression on weighted samples was used to extend results to a population level. Three quarters of 10-12 year olds reported at least one form of maltreatment, with parental physical maltreatment being most common. Males had higher odds of maltreatment in general except for emotional maltreatment. Ethnicity and parental conflict were key factors associated with maltreatment. The study contributes important evidence towards improving public health interventions for child maltreatment prevention in the country.

Med J Malaysia, 2003 Jun;58(2):159-66.
PMID: 14569735 MyJurnal

Over a 2-week period, the management of upper respiratory tract infection by 24 medical officers and medical assistants in Seremban District was studied. Each practitioner recorded clinical data and prescription for twenty consecutive patients using a structured questionnaire. The extent to which the practitioners used "predictive features" (fever, absence of cough, cervical adenopathy, enlarged tonsils and exudates on tonsils) in clinical decision-making was analysed. The mean antibiotic prescription rate was 28.7% (95% CI: 24.6%, 33.0%). The antibiotic prescription rate of medical officers and medical assistants were similar. Five features were independently associated with antibiotic prescription (phlegm, fever, cervical adenopathy, red throat and tonsillar exudates). Antibiotics were prescribed for 22.1% of patients with 0-1 predictive features. High prescribers were 5 times more likely to prescribe antibiotics in this group of patients than low prescribers. To a large extent the clinical decision-making of practitioners in this study was evidence based. However, they were unduly influenced by purulent manifestation (phlegm) and redness of throat. The antibiotic prescription rate in these government health clinics is potentially reducible by means of educational intervention.

Thiopurine methyltransferase polymorphisms in a multiracial asian population and children with acute lymphoblastic leukemia

Kham SK, Tan PL, Tay AH, Heng CK, Yeoh AE, Quah TC

J Pediatr Hematol Oncol, 2002 Jun-Jul;24(5):353-9.
PMID: 12142782

The purpose of this study was to determine the frequency of thiopurine methyltransferase (TPMT) polymorphisms in a multiracial Asian population and to assess its relevance in the management of childhood acute lymphoblastic leukemia (ALL). Six hundred unrelated cord blood samples from 200 Chinese, Malay, and Indian healthy newborns were collected at the National University Hospital, Singapore; an additional 100 children with ALL were analyzed for five of the commonly reported TPMT variant alleles using polymerase chain reaction/restriction fragment length polymorphism and allele-specific polymerase chain reaction-based assays. In the cord blood study, the TPMT*3C variant was detected in all three ethnic groups; Chinese, Malays, and Indians had allele frequencies of 3%, 2.3%, and 0.8%, respectively. The TPMT*3A variant was found only among the Indians at a low allele frequency of 0.5%. The TPMT*6 variant was found in one Malay sample. Among the children with ALL, two white and one Chinese were heterozygous for the TPMT*3A variant and showed intermediate sensitivity to 6-mercaptopurine during maintenance therapy. Three Chinese patients and one Malay patient were heterozygous for the TPMT*3C variant. Mercaptopurine sensitivity could be validated in only one out of four TPMT*3C heterozygous patients. The overall allele frequency of the TPMT variants in this multiracial population was 2.5%. The TPMT*3C was the most common variant allele; TPMT*3A and TPMT*6 were rare. These results support the feasibility of performing TPMT genotyping in all children diagnosed with acute leukemia to minimize toxicity from thiopurine chemotherapy.

Thumboo J, Fong KY, Chan SP, Leong KH, Feng PH, Thio ST, et al.

Lupus, 1999;8(7):514-20.
PMID: 10483028 DOI: 10.1191/096120399678840747

OBJECTIVE: To validate the Medical Outcomes Study Family and Marital Functioning Measures (FMM and MFM) in a multi-ethnic, urban Asian population in Singapore.
METHODS: English speaking Chinese, Malay or Indian SLE patients (n=120) completed a self-administered questionnaire containing the FFM and MFM at baseline, after 2 weeks and after 6 months. Lupus activity, disease-related damage and quality of life were assessed using the British Isles Lupus Assessment Group (BILAG), Systemic Lupus International Collaborating Clinics/American College of Rheumatology (SLICC/ACR) Damage Index and SF-36 Health Survey respectively. Scale psychometric properties were assessed through factor analysis, Cronbach's alpha, quantifying test-retest differences and known-groups construct validity.
RESULTS: Factor analysis of scores obtained at baseline and after 6 months identified 3 factors corresponding to the FFM (1 factor) and the MFM (2 factors). Both scales showed acceptable internal consistency, with Cronbach's alpha of 0.95 for the FFM and 0.70 for the MFM. Mean (s.d.) test-retest differences were -0.31 (3.82) points for the FFM and -0.70 (4.26) points for the MFM. Eleven out of 13 a priori hypotheses relating both the FFM and MFM to demographic, disease and quality of life variables were confirmed, supporting the construct validity of these scales.
CONCLUSION: The FFM and MFM are valid and reliable measures of family and marital functioning in a multi-ethnic cohort of Asian SLE patients in Singapore.

Helicobacter pylori eradication with lansoprazole, amoxycillin and clarithromycin: testing an ideal regimen in a multicultural south east Asian population and examining factors potentially influencing eradication

Kaushik SP, Vu C

Aust N Z J Med, 2000 Apr;30(2):231-5.
PMID: 10833116

BACKGROUND: From European and North American data, it is recommended in the Asia Pacific consensus statement, that one week therapy with a proton pump inhibitor, amoxycillin and clarithromycin be used for Helicobacter pylori eradication, in areas of high metronidazole resistance. The efficacy of this regimen is unknown in Singapore.
AIM: To assess the efficacy, safety and compliance of an H. pylori eradication regimen and examine clinical factors that potentially determine eradication.
METHODS: Consecutive outpatients from a multicultural, south east Asian, population with H. pylori infection, with or without peptic ulcer, were treated with lansoprazole 30 mg, amoxycillin 1 gm, clarithromycin 500 mg, twice a day for seven days. Eradication was assessed by either rapid urease, histology or urea breath test. Compliance and side effects were recorded. The eradication rate and effect of ethnicity, age, sex, usage of alcohol, smoking and non-steroidal anti-inflammatory drugs, history of ulcer and endoscopic diagnosis on eradication were examined by univariate and multivariate analysis.
RESULTS: Of 113 patients, the eradication rate by intention to treat was 98/113 (87%) (95% confidence interval [CI] 80-93%) and per protocol was 98/106 (92%) (95% CI 87-97%). Using Fisher's exact test, eradication was more successful in Chinese (intention to treat and per protocol respectively p=0.02 and p<0.001) compared to non-Chinese. By logistic regression analysis ethnicity was an independent factor associated with eradication success (p=0.0025). Side effects occurred in five (4.4%), resulting in cessation of treatment.
CONCLUSIONS: This one week eradication regimen is safe and effective in south east Asians. Chinese ethnicity may be associated with a higher likelihood of eradication success.
