This study provides a brief view of chronic pulmonary aspergillosis (CPA) in the post-tuberculosis treatment community in Vietnam, a high burden tuberculosis (TB) country. In three months in late 2019, 70 post-TB patients managed at Vietnam National Lung Hospital were enrolled. Of these, 38 (54.3%) had CPA. The male/female ratio was 3/1 (28 males and ten females). CPA patients had a mean age of 59 ± 2.3 years (95%CI 54.4–63.6). The mean Body mass index (BMI) was 19.0 ± 0.5 (18.0–20.0) and 16 of 38 (42.1%) patients had concurrent diseases, the most common of which were chronic obstructive pulmonary disease (COPD) and diabetes. Twenty-six patients (68.4%) developed hemoptysis, 21 (55.3%) breathlessness, and weight loss was seen in 30 (78.9%). Anaemia was seen in 15 (39.5%) and 27 of 38 (71.1%) patients had an elevated C-reactive protein (CRP). The most common radiological findings were multiple cavities (52.6%) and pleural thickening (42.7%), followed by aspergilloma (29.0%) and non-specific infiltrates. There were five of 38 patients (13.2%) with a cavity containing a fungal ball on the chest X-ray, but when the high resolution computed tomography (HRCT) was examined, the number of patients with fungal balls rose to 11 (28.9%). Overall, 34 of 38 (89.5%) cases had an elevated Aspergillus IgG with an optical density ≥ 1, and in 2 cases, it was 0.9–1.0 (5%), borderline positive. In nine patients (23.7%) Aspergillus fumigatus was cultured from sputum. CPA is an under-recognised problem in Vietnam and other high burden TB countries, requiring a different diagnostic approach and treatment and careful management. HRCT and Aspergillus IgG serum test are recommended as initial diagnostic tools for CPA diagnosis.
Introduction: Tuberculous meningitis (TBM) is the most dangerous form of tuberculosis with high mortality and disability rates. However, the delayed diagnostic process is often due to the absence of the gold standard tests leading to a lack of information about the sensitivity and specificity of diagnostic tests. This study aims to estimate the prevalence of TBM and determine the performance of four diagnostic procedures: the mycobacteria growth culture test, Gene Xpert assay, and analysis of protein levels and leukocyte count taken from cerebrospinal fluid. Methodology: We used a Bayesian latent class analysis to estimate the prevalence of TBM with 95% credible interval (CI), and the specificity and sensitivity of the four diagnostic procedures. The area under the receiver operating characteristic curve (AUC) of the cerebrospinal protein levels and leukocyte count were also compared and estimated using different thresholds. Results: A total of 1,213 patients suspected of having TBM were included. The estimated TBM prevalence was 34.8 % (95% CI: 28.8 – 41.3). The sensitivity of culture test and Gene Xpert assay was 62.7% (95% CI: 52.5 – 74.0), and 57.5% (95% CI: 51.0 – 64.0), and the specificity of Gene-Xpert was 95. 9% (95% CI: 92.0 – 99.8). The AUC for leukocyte count was 76.0%, and for protein level was 73.4%. Conclusions: This study provided better information about the performance of four routine diagnostic tests and the prevalence of TBM which can enhance disease control and improve treatment outcomes.
Cystic pulmonary tuberculosis is a unique form of pulmonary tuberculosis (PTB) presenting with multiple reversible cysts of the lung. Unlike the other forms, this cystic lung disease can improve with prompt tuberculosis treatments. Here we report the case of a 15-year-old girl who presented with respiratory failure and severe lung damage at hospital admission. We diagnosed her with PTB based on her positive GeneXpert result test. The patient was treated with a standard tuberculosis regimen for 6 months and recovered completely.
Background: The prevalence of diabetes mellitus in Vietnam is relatively low compared to other Asian countries, but it is accelerating with the economic and cultural transition. This study aimed to estimate the current prevalence and clinical profile of undiagnosed diabetes mellitus in a tertiary hospital in the south of Vietnam. Methods: A cross-sectional investigation was conducted to recruit 1,250 participants, who were at least 18 year-old and were randomly sampled from Cho Ray Hospital, Ho Chi Minh City, Vietnam. Fasting plasma glucose concentration and HbA1c were measured for each individual. The American Diabetes Association criteria were used to diagnose diabetes. Demographic data and other clinical characteristics of diabetes were also documented, including age, sex, residence, educational status, weight, height, waist and hip circumferences, blood pressure, familial history of diabetes, and lipid profile. Results: The prevalence of undiagnosed diabetes mellitus was 7.5% in the population studied. Age, waist circumference, waist-hip ratio, body mass index, and hypertension, as well as dyslipidaemia, were well-correlated with the diabetes rate. Conclusion: The prevalence of undiagnosed diabetes mellitus is increasing far more than expected. Newly diagnosed diabetic patients usually presented with multiple comorbidities including overweight/obesity, hypertension, and dyslipidaemia.
