ABSTRACT

BACKGROUND: Itch as the most common symptom in dermatology has been shown to be related to psychological factors such as stress, anxiety and depression. Moreover, associations were found between perceived stigmatization and itch. However, studies investigating the differences between patients with dermatoses with and without itch regarding perceived stress, stigmatization, anxiety and depression are missing. Therefore, one of the aims of the second study of the European Society for Dermatology and Psychiatry (ESDaP study II) was to investigate these relationships in a large cohort of patients with different itchy dermatoses. RESULTS: 3399 patients with 14 different itchy dermatoses were recruited at 22 centres in 17 European countries. They filled in questionnaires to assess perceived stigmatization, stress, signs of clinically relevant anxiety or depression, itch-related quality of life, the overall health status, itch duration, frequency and intensity. The most significant association between the severity of itching and the perception of stress was observed among individuals with rosacea (correlation coefficient r = 0.314). Similarly, the strongest links between itch intensity and experiences of stigmatization, anxiety, and depression were found in patients with seborrheic dermatitis (correlation coefficients r = 0.317, r = 0.356, and r = 0.400, respectively). Utilizing a stepwise linear regression analysis, it was determined that within the entire patient cohort, 9.3% of the variation in itch intensity could be accounted for by factors including gender, levels of anxiety, depression, and perceived stigmatization. Females and individuals with elevated anxiety, depression, and perceived stigmatization scores reported more pronounced itch intensities compared to those with contrary attributes. CONCLUSION: This study underscores the connection between experiencing itch and its intensity and the psychological strain it places on individuals. Consequently, psychological interventions should encompass both addressing the itch itself and the interconnected psychological factors. In specific cases, it becomes imperative for dermatologists to direct individuals towards suitable healthcare resources to undergo further psychological assessment.

ABSTRACT

OBJECTIVE: This study used the Taiwan Stroke Registry data to evaluate the efficacy and safety of intravenous tissue plasminogen activator (tPA) in treating acute ischemic stroke in patients with renal dysfunction. DESIGN: We identified 3525 ischemic stroke patients and classified them into two groups according to the estimated glomerular filtration rate (eGFR) at the emergency department: ≥60, and <60 ml/min/1.73 m2 or on dialysis and by the propensity score from August 2006 to May 2015. The odds ratio of poor functional outcome (modified Rankin Scale ≥2) was calculated for patients with tPA treatment (N = 705), compared to those without tPA treatment (N = 2820), by eGFR levels, at 1, 3 and 6 months after ischemic stroke. We also evaluated the risks of intracerebral hemorrhage, upper gastrointestinal bleeding, mortality, between the two groups by eGFR levels. RESULTS: Among patients with eGFR levels of <60 ml/min/1.73 m2, tPA therapy reduced the odds ratio of poor functional outcome to 0.60 (95% confidence interval = 0.42-0.87) at 6 months after ischemic stroke. The tPA therapy was not associated with increased overall risk of upper gastrointestinal bleeding, but with increased risk of intracerebral hemorrhage. The low eGFR was not a significant risk factor of intracerebral hemorrhage among ischemic stroke patients receiving tPA treatment. CONCLUSIONS: tPA for acute ischemic stroke could improve functional outcomes without increasing the risks of upper gastrointestinal bleeding for patients with or without renal dysfunction. The low eGFR was not a significant risk factor for intracerebral hemorrhage among patients receiving tPA treatment.

ABSTRACT

BACKGROUND: Hair diseases play an important burden on patients' lives, causing significant emotional and psychosocial distress. However, the impairment due to different hair conditions, such as alopecia areata (AA) and androgenetic alopecia (AGA), has rarely been compared. OBJECTIVE: The aim of this study was to assess the psychological burden of subgroups of patients with different hair diseases and to compare them to a healthy population. METHODS: In this study, we analysed a subgroup of patients with hair diseases from patients of a large multicentre study including 3635 dermatological patients and 1359 controls from 13 European countries. In the subgroup of patients with hair diseases, we analysed the socio-demographic characteristics, the stress level, and the impact of hair diseases on quality of life (QoL), anxiety, and depression and we compared them among patients with AA, AGA and healthy controls. RESULTS: The study population included 115 patients (77% women, 23% men) with hair diseases, 37 of whom with AA and 20 with AGA. Patients with hair diseases had a lower education level than healthy controls (medium educational level: 43% vs. 28%). Overall, 41% of the patients reported stressful life events during the last 6 months compared with 31% of the controls. Patients with the same age, sex, depression level and comorbidities had a worse QoL when suffering from AA than from AGA (Mean Dermatology Life Quality Index score: 5.8 vs. 2.5). CONCLUSION: Patients with hair diseases are more anxious, depressed and have a lower QoL than controls.

ABSTRACT

BACKGROUND AND PURPOSE: Studies on using antiplatelet agents for secondary prevention in ischaemic stroke patients with renal dysfunction are limited. The Taiwan Stroke Registry database was used to compare the efficacy of antiplatelet agents. METHODS: From the Taiwan Stroke Registry data, 39 174 acute ischaemic stroke patients were identified and were classified into three groups by antiplatelet agent: aspirin, clopidogrel and dual antiplatelet therapy (DAPT) with a combination of aspirin and clopidogrel. The re-stroke incidence and 1-year mortality were stratified by estimated glomerular filtration rate (eGFR) levels at admission: ≥90, 60-89 and <60 ml/min/1.73 m2 or on dialysis. RESULTS: Compared to the aspirin group, the re-stroke differences were not statistically significant for the clopidogrel group [adjusted subhazard ratio 0.95, 95% confidence interval (CI) 0.84-1.08] and the DAPT group (adjusted subhazard ratio 1.03, 95% CI 0.77-1.39) after controlling for the competing risk of death. The mortality rate increased as the eGFR level declined. In addition, compared to patients taking aspirin, there was no statistically significant difference in overall 1-year mortality for the clopidogrel group (adjusted hazard ratio 1.11, 95% CI 0.95-1.29) and for the DAPT group (adjusted hazard ratio 1.01, 95% CI 0.67-1.54). The results were consistent in different subgroups stratified by eGFR levels. CONCLUSIONS: There was no difference in the risks of recurrent stroke and 1-year mortality amongst ischaemic stroke patients with or without renal dysfunction receiving antiplatelet agents with aspirin, clopidogrel or dual agents with a combination of aspirin and clopidogrel, regardless of their renal dysfunction status.

ABSTRACT

BACKGROUND: Prurigo is defined by the presence of chronic pruritus and multiple localized or generalized pruriginous lesions. OBJECTIVE: The aim of this study was to assess the psychological burden of prurigo in patients of European countries. METHODS: In this multicentre European study, 3635 general dermatology outpatients and 1359 controls were included. Socio-demographic data and answers to questionnaires (regarding quality of life, general health, anxiety and depression and suicidal ideation) were collected. RESULTS: There were 27 patients with prurigo; of these, 63% were men, and the mean age was 58.6 years. Among patients with prurigo, 10 of 27 (37%) suffered from anxiety and 8 of 27 (29%) from depression. Suicidal ideation was reported in 5 of 27 (19%) patients, and for four of these five patients, suicidal ideation was related to their skin disease. These frequencies were higher in the 10 commonest dermatological diseases (including psoriasis, atopic dermatitis and leg ulcers). The impact on quality of life was severe, with a mean Dermatologic Life Quality Index (DLQI) of 12.4, with an extreme impact on quality of life for 23% of patients and a very large impact for 27% of patients. CONCLUSION: The psychological comorbidities of prurigo are common, greater than those of other skin diseases, and their impact on quality of life is significant. Thus, it is important to study this condition and to find new treatments.

ABSTRACT

BACKGROUND: Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system. Few studies focused on the relationship between septicemia and MS. AIM: To evaluate the potential impact of septicemia on risk for MS. DESIGN: Two cohorts of patients with septicemia and without septicemia were followed up for the occurrence of MS. METHODS: Patients of 482 790 with septicemia was enrolled from the National Health Insurance Research Database between 2001 and 2011 as the study group to match the 1 892 820 individuals, as the control group, by age and gender. Incidence of MS in both groups was calculated. Cox proportional-hazards regressions were performed for investigating hazard ratios (HR) for MS between groups. RESULTS: Septicemia patients had a 3.06-fold (95% CI: 2.16-4.32, P < 0.001) greater risk of developing MS than the matched group. In addition, higher severity of septicemia was associated with higher risk of developing MS (moderate: HR = 4.03, 95% CI: 2.53-6.45, P < 0.001; severe: HR = 11.1, 95% CI: 7.01-17.7, P < 0.001). Similar results also occurred in both male and female patients with septicemia (male: HR = 4.06, 95% CI: 2.17-7.58, P < 0.001; female: HR = 2.72, 95% CI: 1.79-4.11, P < 0.001). Patients without counterpart comorbidities had a significantly higher risk of MS than the controlled group (HR = 3.02, 95% CI: 2.10-4.35, P < 0.001). CONCLUSION: The results indicated septicemia is linked to an increased risk for MS. Aggressively preventing and treating septicemia may be warranted for one of precautionary strategies of MS.

ABSTRACT

Recovery in co-occurring mental health and substance use disorders often involves relationships with professional helpers, yet little is known about how these are experienced by service users. The aim of this study was to explore and describe behaviour and attributes of professional helpers that support recovery, as experienced by persons with co-occurring disorders. Within a collaborative approach, in-depth individual interviews with eight persons with lived experience of co-occurring disorders were analysed using systematic text condensation. The analysis yielded four categories of recovery-supporting behaviour and attributes of professional helpers and the ability to build trust cuts across all of them: Building trust through (a) hopefulness and loving concern, (b) commitment, (c) direct honesty and expectation and (d) action and courage. Services should allow for flexibility and continuity, and training should recognise the importance of establishing trust in order to reach out to this group.

ABSTRACT

BACKGROUND: It was recently demonstrated that a significant number of patients with common skin diseases across Europe are clinically depressed and anxious. Studies have shown that physicians not trained as psychiatrists underdiagnose depression. This has not been explored among dermatologists. OBJECTIVES: To estimate the concordance between clinical assessment of depression and anxiety by a dermatologist and assessment with the Hospital Anxiety and Depression Scale (HADS). METHODS: The study was an observational cross-sectional multicentre study of prevalent cases of skin diseases in 13 countries in Europe. Consecutive patients were recruited in outpatient clinics and filled in questionnaires prior to clinical examination by a dermatologist who reported any diagnosis of skin disease and signs of mood disorders. RESULTS: Analysis of the 3635 consultations showed that the agreement between dermatologist and HADS was poor to fair (lower than 0·4) for all diagnosis categories. The true-positive rate (represented by the percentage of dermatologists recognizing signs of depression or anxiety in patients with depression or anxiety as defined by a HADS value ≥ 11) was 44·0% for depression and 35·6% for anxiety. The true negative rate (represented by the percentage of dermatologists not detecting signs of depression or anxiety in non-depressed or non-anxious patients defined by HADS-value < 11) was 88.8% for depression and 85.7% for anxiety. CONCLUSIONS: Dermatologists in Europe tend to underestimate mood disorders. The results suggest that further training for dermatologists to improve their skills in diagnosing depression and anxiety might be appropriate. When present, the psychological suffering of patients with dermatological conditions needs to be addressed.

ABSTRACT

BACKGROUND AND PURPOSE: Physical activity is associated with a reduced incidence of first-time stroke. However, few studies have examined the effect of pre-stroke physical activity on post-stroke complications and clinical outcomes. METHODS: A total of 39 835 cases of stroke registered in the nationwide stroke registry system of Taiwan between 2006 and 2009 were analyzed according to five levels of severity as determined by National Institutes of Health Stroke Scale score upon hospital admission. Pre-stroke physical activity was defined in the Taiwan Stroke Registry as dedicated leisure-time physical activity for at least 30 min/day for 3 days/week for more than 6 months. A Cox model was used to compare complications and outcomes between active and inactive groups. RESULTS: The active and inactive groups were similar in age distribution and stroke type distribution, but the active group had better National Institutes of Health Stroke Scale scores upon admission. The active group also had significantly fewer post-stroke complications. Active patients had lower hospital mortality and better functional outcomes upon discharge as per the modified Rankin Scale. Improved functional status in the active group was significant at 1, 3 and 6 months post-stroke. CONCLUSION: Dedicated leisure-time physical activity for at least 30 min/day, at least three times per week for more than 6 months was associated with decreased stroke severity, fewer post-stroke complications, lower mortality and better outcomes.

ABSTRACT

BACKGROUND: Generic instruments measuring health-related quality of life (HRQoL), like EQ5D™, enable comparison of skin diseases with healthy populations and nondermatological medical conditions, as well as calculation of utility data. OBJECTIVES: To measure HRQoL in patients with common skin diseases and healthy controls across Europe using the EQ5D. METHODS: This multicentre observational cross-sectional study was conducted in 13 European countries. Each dermatology clinic recruited at least 250 consecutive adult outpatients to complete questionnaires, including the EQ5D. RESULTS: There were 5369 participants (4010 patients and 1359 controls). Mean ± SD self-rated health state reported by patients was 69·9 ± 19·7; for controls it was 82·2 ± 15·5. When adjusted for confounding factors, including comorbidity, mean patient EQ visual analogue scores were 10·5 points lower than for controls (standardized ß = -0·23). Odds ratio with 95% confidence interval for impairment in all five dimensions of EQ5D adjusted for confounders was doubled for patients compared with controls. Patients with hidradenitis suppurativa (HS), blistering conditions, leg ulcers, psoriasis and eczemas had the highest risk for reduction in HRQoL in most dimensions (2-10-fold). Data on differences of impairment by dimensions offer new insights. CONCLUSIONS: This study confirms the large impact skin conditions have on patients' well-being, differentiating between aspects of HRQoL. Patients with HS, blistering diseases, leg ulcers, infections and most chronic skin diseases reported reduced HRQoL compared with patients with chronic obstructive lung disease, diabetes mellitus, cardiovascular disease and cancers. These findings are important in the prioritization of resource allocation between medical fields and within dermatological subspecialities.

ABSTRACT

PURPOSE: Hopelessness is associated with increased adverse events and decreased survival in patients with coronary heart disease (CHD). The purpose of this research was to examine the effect of regular home- and hospital-based cardiac rehabilitation (CR) exercise on hopelessness levels in patients with CHD, hypothesizing that increased exercise in either setting would lead to decreased state hopelessness. METHODS: A descriptive longitudinal design was used at a large teaching hospital in Michigan. A total of 324 patients provided data during hospitalization and at least 1 followup time point (3, 8, and 12 months). RESULTS: The patients had persistent, modest levels of state and trait hopelessness across all time points. Among home exercisers with moderate to severe state hopelessness at baseline, both mean state (P = .002) and trait (P = .02) hopelessness were reduced at later time points compared with those who quit or did not start exercise. Multivariable models showed that when individuals had moderate to severe baseline state hopelessness, home exercise remained associated with decreases in state hopelessness compared with no exercise, even after adjusting for hospital exercise, depression, and demographic variables. CONCLUSIONS: Exercise may be effective in reducing moderate to severe hopelessness in patients with CHD. Moderate to severe baseline state hopelessness was a predictor of attrition in this cohort, especially for home exercisers, but this was mediated in hospital-based programs. Further research is needed to determine how hopeless individuals can be encouraged to exercise and whether home- or a hospital-based CR exercise is superior in impacting hopelessness.

ABSTRACT

Recently, a genome-wide screening identified a functional single-nucleotide polymorphism in dual-specificity phosphatase 14 gene (DUSP14), which was associated with pulmonary tuberculosis (TB) in a West African study. DUSP14 regulates T-cell proliferation and cytokine production in a negative way via dephosphorylation and inactivation of key signaling molecules. The aim of this study is to further explore the possible significance of the DUSP14 polymorphism. Total RNA was extracted from the whole blood of 109 healthcare workers (HCWs) in Vietnam and subjected to quantitative reverse-transcription PCR for DUSP14 and 20 immune-related genes. DUSP14 rs1051838 was genotyped in 502 new pulmonary TB patients and 506 healthy controls. Among disease-free individuals (HCWs), T-helper type-1 (Th1)-related genes, interferon-gamma receptor 2 (IFNGR2) and signal transducer and activator of transcription-1 (STAT1) mRNA levels significantly increased as the number of A alleles of rs1051838 increased, whereas the DUSP14 mRNA level tended to decrease. The AA genotype was associated with protection against active TB in younger patients (⩽45 years old, OR=0.63, 95% CI 0.44-0.90). Our results suggest that a low-expression genotype of DUSP14 accompanied by high transcript levels of Th1 immune-related genes may confer protection against early TB development.

ABSTRACT

Hopelessness is predictive in the development of coronary heart disease (CHD) and can persist in patients after a CHD event, adversely affecting recovery. Hopelessness may represent a temporary response (state) or a chronic outlook (trait). Common hopelessness measures fail to differentiate state from trait hopelessness, a potentially important differentiation for treatment. The State-Trait Hopelessness Scale (STHS) was developed and pilot tested with two groups of college students (n = 39 and 190) and patients with CHD (n = 44). The instrument was then used with 520 patients, confirming reliability (Cronbach's α) for the State (.88) and Trait (.91) subscales and concurrent and predictive validity. Separate exploratory factor analyses showed two factors (hopelessness present or hopelessness absent) for the State and Trait subscales, accounting for 58.9% and 57.3% of variance, respectively. These findings support future use of the tool in clinical settings and in intervention studies focused on hopelessness.

ABSTRACT

BACKGROUND: The Weight Loss Maintenance Trial tested strategies for maintenance of weight loss. Personal contact was superior to interactive technology and self-directed conditions. PURPOSE: We aimed to identify behavioral mediators of the superior effect of personal contact vs. interactive technology and of personal contact vs. self-directed arms. METHODS: Overweight/obese adults at risk for cardiovascular disease (n = 1,032) who lost at least 4 kg were randomized to personal contact, interactive technology, or self-directed. After 30 months, 880 participants had data on weight and behavioral strategies. RESULTS: Reported increase of intake of fruits and vegetables and physical activity and more frequent self-weighing met criteria as mediators of the better outcome of personal contact vs. interactive technology. Increased intake of fruits and vegetables, more frequent self-weighing, and decreased dessert consumption were mediators of the difference between personal contact vs. self-directed. CONCLUSION: Inducing changes in the identified behaviors might yield better outcomes in future weight loss maintenance trials.

ABSTRACT

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and is a major cause of morbidity and mortality worldwide. Many candidate genes have been investigated for a possible association with TB. Toll-like receptors (TLRs) are known to play important roles in human innate immune systems. Polymorphisms in and functions of TLRs have been investigated to identify associations with specific infectious diseases, including TB. Here, we examined whether single-nucleotide polymorphisms (SNPs) in TLRs and genes in TLR signaling were associated with TB susceptibility in Indonesian and Vietnamese populations. A statistically significant association was observed between TB susceptibility in a classified Indonesian female group and rs352139, an SNP located in the intron of TLR9, using the genotype (P = 2.76E-04) and recessive (AA vs AG+GG, P = 2.48E-04, odds ratio = 1.827, 95% confidence interval = 1.321-2.526) models. Meta-analysis of the Indonesian and Vietnamese populations showed that rs352139 was significantly associated with TB in the recessive model. This finding indicated that a TLR9 polymorphism might have an important role in the susceptibility to M. tuberculosis in Asian populations.

ABSTRACT

AIMS/HYPOTHESIS: Insulin resistance (IR) improves with weight loss, but this response is heterogeneous. We hypothesised that metabolomic profiling would identify biomarkers predicting changes in IR with weight loss. METHODS: Targeted mass spectrometry-based profiling of 60 metabolites, plus biochemical assays of NEFA, ß-hydroxybutyrate, ketones, insulin and glucose were performed in baseline and 6 month plasma samples from 500 participants who had lost ≥4 kg during Phase I of the Weight Loss Maintenance (WLM) trial. Homeostatic model assessment of insulin resistance (HOMA-IR) and change in HOMA-IR with weight loss (∆HOMA-IR) were calculated. Principal components analysis (PCA) and mixed models adjusted for race, sex, baseline weight, and amount of weight loss were used; findings were validated in an independent cohort of patients (n = 22). RESULTS: Mean weight loss was 8.67 ± 4.28 kg; mean ∆HOMA-IR was -0.80 ± 1.73, range -28.9 to 4.82). Baseline PCA-derived factor 3 (branched chain amino acids [BCAAs] and associated catabolites) correlated with baseline HOMA-IR (r = 0.50, p < 0.0001) and independently associated with ∆HOMA-IR (p < 0.0001). ∆HOMA-IR increased in a linear fashion with increasing baseline factor 3 quartiles. Amount of weight loss was only modestly correlated with ∆HOMA-IR (r = 0.24). These findings were validated in the independent cohort, with a factor composed of BCAAs and related metabolites predicting ∆HOMA-IR (p = 0.007). CONCLUSIONS/INTERPRETATION: A cluster of metabolites comprising BCAAs and related analytes predicts improvement in HOMA-IR independent of the amount of weight lost. These results may help identify individuals most likely to benefit from moderate weight loss and elucidate novel mechanisms of IR in obesity.

ABSTRACT

AIMS: The aim of this study is to examine the possible changes in depressive symptoms related to various adverse experiences, based on a three-year follow-up among adolescents. METHODS: All 10(th) graders invited to enter the youth section of the Oslo Health Study 2001 (n = 3,811) constituted a baseline of a longitudinal study. A high level of mental distress (Hscl-10 score ≥ 1.85) according to the different life experiences was compared, at baseline (15 years) and follow-up (18 years). RESULTS: All adverse experiences were associated with a high Hscl-10 score except parents not living together and death of a close person at 15 and 18 years for boys, and death of a close person at 18 years of age for girls. A development from high Hscl-10 score at baseline to low score at follow up was defined as recovery from mental distress. The proportion of the youth that had a high Hscl-10 score related to reporting adverse life experiences at age 15, followed by a low Hscl-10 score three years later proved to be between 44% and 89% among boys and between 16% and 31% among girls. CONCLUSIONS: From a three year longitudinal perspective the recovery from mental distress is substantial and higher among boys than among girls. However, mental distress seems to persist in a considerable proportion of the adolescents. Consequently, it is insufficient to brush aside traumas and hurt and rely on a time healing process only.

ABSTRACT

Allele and haplotype frequencies of the human leukocyte antigens (HLA) were studied in the Kinh Vietnamese population. We analyzed 170 unrelated healthy individuals. DNA-based HLA typing was performed using a microsphere-based array genotyping platform with sequence-specific oligonucleotide probes to distinguish HLA-A, -B, -C, -DRB1 and -DQB1 alleles. A total of 21 HLA-A, 37 HLA-B, 18 HLA-C, 25 HLA-DRB1, and 14 HLA-DQB1 alleles were identified. HLA-A*1101, A*2402, A*3303, B*1502, B*4601, Cw*0102, Cw*0702, Cw*0801, DRB1*1202, DQB1*0301, DQB1*0303, and DQB1*0501 were found with frequencies higher than 10%. Two representative haplotypes bearing two to five HLA loci were A*1101-B*1502 and A*3303-B*5801 for HLA-A-B; Cw*0801-B*1502 and Cw*0102-B*4601 for HLA-C-B; B*1502-DRB1*1202 and B*4601-DRB1*0901 for HLA-B-DRB1; DRB1*1202-DQB1*0301 and DRB1*0901-DQB1*0303 for HLA-DRB1-DQB1; A*1101-Cw*0801-B*1502 and A*3303-Cw*0302-B*5801 for HLA-A-C-B; A*1101-B*1502-DRB1*1202 and A*2901-B*0705-DRB1*1001 for HLA-A-B-DRB1, A*1101-Cw*0801-B*1502-DRB1*1202-DQB1*0301 and A*2901-Cw*1505-B*0705-DRB1*1001-DQB1*0501 for HLA-A-C-B-DRB1-DQB1. Allele distribution and haplotype analysis demonstrated that the Vietnamese population shares HLA patterns with southern Chinese, Thai, Javanese and Micronesians, while it also retains unique characteristics.

ABSTRACT

BACKGROUND: Itch is a major symptom in dermatology but is little explored epidemiologically. Objective To describe the prevalence and the severity of itch, and to explore its relation to psychosocial factors. METHODS: The design was cross-sectional and population-based. A total of 40 880 adults in Oslo were invited to answer a questionnaire. RESULTS: Twenty-seven per cent report itch. Individuals reporting itch were younger, the majority were female, were non-Norwegian, had lower income, were more distressed, had experienced more negative life events and had poorer social support. Individuals with poor support who had experienced more negative life events reported more itch than individuals with good support (15. 6% compared to 10. 9%). The strong association with psychosocial factors was confirmed in a logistic regression. CONCLUSION: There is a strong association between itch and psychosocial factors in the general population.

ABSTRACT

OBJECTIVE: To assess the prevalence of tuberculosis (TB) in Hanoi, Vietnam, in 2003/2004. METHODS: A random selection was carried out involving 11624 subjects from 20 communes within the city. RESULTS: On chest X-ray examination, 317 subjects (2.73%) showed abnormal lung opacity, of which 17 were sputum smear-positive, two concentrated smear-positive and three culture-positive, all with active TB. The prevalence of sputum smear-positive pulmonary TB was 146 per 100000 in persons aged >or=15 years (95%CI 65-228). CONCLUSION: This is the first large-scale assessment of the prevalence of TB in Hanoi. The prevalence rate was higher than expected, suggesting that a significant number of patients with active TB, particularly females, remain undiagnosed, thus representing a continuing potential source of transmission in the community.
