Other sites for genital tuberculosis include the Fallopian tubes and the endometrium. Genital tuberculosis and other types of tuberculosis outside the lungs are referred to as extra-pulmonary tuberculosis (EPTB). Genital tuberculosis presents with unspecific symptoms and signs;and because of this, most often, the diagnosis is made incidentally during investigations for other conditions that present with similar clinical pictures. Therefore, misdiagnosis and wrong treatment are not uncommon. We present a case of tuberculosis of the uterine cervix which was incidentally diagnosed when the patient was being investigated for cervical cancer, and successfully treated with a 6-months rifampicin regimen, 2RHZE/4HRE. Health providers have a duty to highly suspect tuberculosis of the cervix among women who present with abnormal vaginal discharge, abnormal vaginal bleeding and post-coital bleeding especially in countries where HIV and TB are endemic. If properly diagnosed and correctly treated, tuberculosis of the uterine cervix is curable.展开更多

Drug resistance is difficult to treat due to its associated cost and side effects. The objective of this study was to assess the drug resistance pattern and assess risk factor associated with MDR-TB among pulmonary tuberculosis patients attending National Tuberculosis Center. Methodology: The comparative cross sectional study was conducted at National Tuberculosis Center during August 2015 to February 2015. Early morning sputum samples were collected from pulmonary tuberculosis suspected patients and subjected to Ziehl-Neelsen staining and fluorochrome staining and culture on Lowenstein-Jensen (LJ) medium. Drug Susceptibility test was performed on culture positive isolates by using proportion method. Univariate and multivariate analysis was computed to assess the risk factors of MDR-TB. Results: Out of 223 sputum samples, 105 were fluorochrome staining positive, 85 were ZN staining positive and 102 were culture positive. Out of 102 culture positive isolates, 37.2% were resistance to any four anti-TB drugs. 11 (28.9%) were initial drug resistance and 28 (43.7%) were acquired drug resistance. The overall prevalence of MDR-TB was 11.7%, of which 2 (5.3%) were initial MDR-TB and 10 (15.6%) were acquired MDR-TB. Univariate and multivariate analysis showed female were significantly associated (P = 0.05) with MDR-TB. Conclusion: Drug resistance TB particularly MDR-TB is high. The most common resistance pattern observed in this study was resistance to both isoniazid and rifampicin. Female were found to be associated with MDR-TB. Thus, early diagnosis of TB and provision of culture and DST are crucial in order to combat the threat of DR-TB.展开更多

To analyze ten cases of MGTT with pulmonary metastasis complicated with pulmonary tuberculosis in our hospital from 1980 to 1997 retrospectively. Results.From the x ray film, there are great resemblances between MGTT with pulmonary metastasis and pulmonary tuberculosis. Of 10 patients, 7 of them were examined out pulmonary tuberculosis during the chemotherapy of MGTT. Pulmonary tuberculosis appeared six months before chemotherapy in three cases. All of the patients were treated with multiagent chemotherapy. Seven patients achiceved a complete remission, 2 patients developed drug resistance and died of cerebral haemorrhage and cerebral herniation, 1 woman who had achieved a complete remission from MGTT for 14 months died of miliary tuberculosis. Conclusion. It is very important to make differential diagnosis of the MGTT with pulmonary metastasis complicated with pulmonary tuberculosis. Trying to avoid excessive anti tumor treatment owing to mistake pulmonary tuberculosis for pulmonary metastasis, and avoiding missing an opportunity of anti tuberculosis treatment because of missed diagnosis should be emphasized.展开更多
文摘Detection and treatment of drug resistance in extrapulmonary tuberculosis(EPTB)is a major challenge worldwide.Drug resistance in EPTB has not been studied extensively.However,patients with drug-resistant EPTB have been reported to have poor outcomes[1].Rifampicin and isoniazid are the cornerstone drugs in the management of EPTB.Resistance in Mycobacterium(M.)tuberculosis to these drugs commonly arises due to mutations in the‘rpoB’gene and‘katG&inhA’genes,which confer resistance to rifampicin and isoniazid,respectively.Treatment outcomes are affected by the presence of these mutations.In addition,anatomical and physiological barriers impede the effective delivery of drugs to the affected extrapulmonary site[1].An analysis of the frequency of mutations in drug resistant M.tuberculosis strains causing EPTB in our region can help identify patterns of drug resistance.This,in turn,can provide inputs that may be used for modifying standard treatment regimens to make them more effective.The present study aims to identify the frequency and pattern of mutations in the‘rpoB’gene and‘katG&inhA’genes in M.tuberculosis strains isolated from EPTB samples.

文摘Tuberculosis of the uterine cervix is grouped under genital tuberculosis. Other sites for genital tuberculosis include the Fallopian tubes and the endometrium. Genital tuberculosis and other types of tuberculosis outside the lungs are referred to as extra-pulmonary tuberculosis (EPTB). Genital tuberculosis presents with unspecific symptoms and signs;and because of this, most often, the diagnosis is made incidentally during investigations for other conditions that present with similar clinical pictures. Therefore, misdiagnosis and wrong treatment are not uncommon. We present a case of tuberculosis of the uterine cervix which was incidentally diagnosed when the patient was being investigated for cervical cancer, and successfully treated with a 6-months rifampicin regimen, 2RHZE/4HRE. Health providers have a duty to highly suspect tuberculosis of the cervix among women who present with abnormal vaginal discharge, abnormal vaginal bleeding and post-coital bleeding especially in countries where HIV and TB are endemic. If properly diagnosed and correctly treated, tuberculosis of the uterine cervix is curable.
文摘BACKGROUND Bedaquiline is among the prioritized drugs recommended by the World Health Organization for the treatment of extensively drug-resistant tuberculosis(XDRTB).Many patients have not achieved better clinical improvement after bedaquiline is stopped at 24 wk.However,there is no recommendation or guideline on bedaquiline administration beyond 24 wk,which is an important consideration when balancing the benefit of prognosis for XDR-TB against the uncertain safety concerning the newer antibiotics.CASE SUMMARY This paper reported 2 patients with XDR-TB(a female of 58 years of age and a female of 18 years of age)who received bedaquiline for 36 wk,as local experience to be shared.The 2 cases had negative cultures after 24 wk of treatment,but lung imaging was still positive.After discussion among experts,the consensus was made to bedaquiline prolongation by another 12 wk.The 36-wk prolonged use of bedaquiline in both cases achieved a favorable response without increasing the risk of cardiac events or new safety signals.CONCLUSION Longer regimen,including 36-wk bedaquiline treatment,might be an option for patients with XDR-TB.More studies are needed to explore the effectiveness and safety of prolonged use of bedaquiline for 36 wk vs standard 24 wk in the treatment of multidrug-resistant/XDR-TB or to investigate further the biomarkers and criteria indicative for extension of bedaquline to facilitate clinical use of thisnovel drug.
文摘Objective:To investigate and compare the demographic characteristics,clinical findings,and laboratory results of pulmonary tuberculosis(PTB)and extrapulmonary tuberculosis(EPTB)patients,among Turkish citizens,and foreign nationals.Methods:This study included patients aged 18 and over,both Turkish citizens and foreign nationals,diagnosed with PTB or EPTB between 2016 and 2022.All patients were divided into PTB and EPTB group,and demographic characteristics,clinical findings,and laboratory results were compared.Patients with both PTB and EPTB were not included in the comparison.Multivariate logistic regression analysis was conducted to identify potential risk factors for PTB.Results:Among the 261 TB cases included,46 patients(17.6%)had PTB,and 188(72%)had EPTB.The percentage of female patients was significantly higher(P=0.003)in EPTB compared to PTB group.While the prevalence of diabetes mellitus(P=0.002),hypertension(P=0.017),coronary obstructive pulmonary disease(P=0.001),congestive heart failure(P=0.005),coronary artery disease(P=0.001)and immunosuppressive medication use(P=0.017)were significantly higher in PTB patients than in EPTB patients.Multivariate logistical analysis reveals that male(OR 2.6,95%CI 1.3-5.5,P=0.009),diabetes mellitus(OR 2.7,95%CI 1.2-6.1,P=0.015),and asthma(OR 6.3,95%CI 1.2-33.9,P=0.032)were associated with an increased risk of PTB.Social security coverage(P<0.001)and regular employment status(P<0.001)were found to be lower and the presence of multidrug resistance(P=0.002),isoniazid resistance(P=0.012),and rifampin resistance(P=0.012)were found to be significantly higher in foreign-national TB patients comparing with Turkiye citizens.Conclusions:Patients with PTB need to be evaluated for comorbidities and PTB should be investigated in men,in patients with diabetes mellitus or asthma if there are clinical findings suspicious for TB.TB screening for foreign nationals upon entry into the country is essential for TB control and elimination.
文摘BACKGROUND Orificial tuberculosis is a rare type of tuberculosis,which is easy to be misdiagnosed,and can cause great damage to the perianal skin and mucosa.Early diagnosis can avoid further erosion of the perianal muscle tissue by tuberculosis bacteria.CASE SUMMARY Here,we report a case of disseminated tuberculosis in a 62-year-old male patient with a perianal tuberculous ulcer and active pulmonary tuberculosis,intestinal tuberculosis and orificial tuberculosis.This is an extremely rare case of cutaneous tuberculosis of the anus,which was misdiagnosed for nearly a year.The patient received conventional treatment in other medical institutions,but specific treatment was delayed.Ultimately,proper diagnosis and treatment with standard anti-tuberculosis drugs for one year led to complete cure.CONCLUSION For skin ulcers that do not heal with repeated conventional treatments,consider ulcers caused by rare bacteria,such as Mycobacterium tuberculosis.
文摘Aim:To explore the diagnostic value of spiral CT chest enhanced scan for adults with active pulmonary tuberculosis.Methods:The clinical data of 60 adult patients with active pulmonary tuberculosis who were treated in our hospital from January 2018 to November 2019 were retrospectively analyzed.All patients underwent conventional chest radiography and spiral CT chest enhanced scan.The number of tuberculosis diagnosis,the detection rate of special site lesions,and the detection rate of active pulmonary tuberculosis signs by the two methods were compared.Results:In 60 patients,the pathological results confirmed the existence of 75 tuberculosis lesions.The detection rate of spiral CT was 98.67%,which was not statistically significant compared with the detection rate of 92.00%(P>0.05)in the conventional chest X-ray.The detection rate of spiral CT enhanced scans for tuberculosis lesions in special sites was 100.00%,which was significantly higher than that of conventional chest X-ray of 7.69%,and the accuracy rate of active pulmonary tuberculosis signs was 98.85%higher than that of conventional chest X-ray of 79.31%.P<0.05).The difference was statistically significant(P<0.05).Conclusion:Spiral CT chest enhanced scan can not only find special tuberculosis lesions that cannot be detected by conventional chest radiography,but also accurately determine active pulmonary tuberculosis in adults,which is of high diagnostic value.

文摘Objective:To analyze the risk factors associated with multidrug-resistant tuberculosis(MDR-TB)as a first national survey in Indonesia.Methods:This national coverage cross-sectional study was conducted from 2017 to 2018.The study subjects were selected using a multi-stage probability random sampling method.MDR-TB is tuberculosis caused by bacteria resistant to at least isoniazid and rifampicin.The dependent variable was MDR-TB.Independent variables included age,sex,education,employment status,place of residence,history of living with TB patients,and the number of household members.Univariate and multivariate logistic regression models were used to analyze the risk factors associated with MDR-TB.All the data were analyzed using STATA V.14.0(Stata Corp LLC,College Station,TX).Results:This study found the MDR rate was 109/3234(3.4%)among positive pulmonary TB patients.More than twice as many patients had MDR re-treatment(74/3234,2.3%),compared to 35/3234(1.1%)who had new TB diagnoses or were getting initial treatment.After adjusting for employment status,individuals with a prior history of tuberculosis treatment were found to have significantly higher odds of developing MDR-TB,with an odds ratio of 7.22(95%CI 3.87-13.44).Conclusions:Increasing attention should be paid to these patients to prevent MDR-TB,and MDR-TB transmission is an urgent challenge for controlling TB worldwide.Early detection of MDR-TB is a critical part of TB control programs.
文摘There is a bidirectional association between type II diabetes mellitus(T2DM)and pulmonary tuberculosis(PTB),with each enhancing the risk of the other,thus increasing the burden of both drug-sensitive and drug-resistant forms of the disease.This dual burden also has a detrimental impact on patient's mental health.Although several recommendations have been made for bidirectional screening of diabetes and tuberculosis,implementation remains poor,resulting in increased morbidity and mortality among patients with this comorbidity.Mental health is often neglected,as clinical outcomes receive disproportionate focus,with limited attention to patients’social and psychological well-being.According to the World Health Organization,health is defined as a state of physical,mental,and social well-being,and not merely the absence of disease or infirmity.The aim of this mini-review is to highlight the intersection of PTB and T2DM,specifically discussing the mental health outcomes of the co-burden.
文摘BACKGROUND Tuberculosis(TB)remains a global health concern despite decreasing incidence.Delayed TB diagnosis can exacerbate patient outcomes and lead to broader public health issues such as mass infections.Differentiation between TB and bacterial pneumonia is often complicated by variable clinical and radiological manifestations of TB,leading to diagnostic delays.CASE SUMMARY An 89-year-old,Japanese male patient with a history of diabetes mellitus,hypertension,and hypothyroidism presented with right-sided chest pain.Based on the elevated inflammatory response,right pleural effusion,and infiltrating shadow in the lung field,the diagnosis of right pleurisy was made and the antibiotic,ampicillin/sulbactam,was administered.The patient’s condition,inflammatory reaction,and right pleural effusion temporarily improved.However,persistent low-grade fever and malaise prompted further evaluation,revealing repeated right pleural effusion and inflammatory response.A right thoracentesis was performed;the patient was diagnosed with tuberculous pleurisy as a result of exudative effusion with lymphocyte predominance,elevated adenosine deaminase levels,and positive Mycobacterium TB polymerase chain reaction test.Anti-TB treatment,including isoniazid,rifampicin,and ethambutol was initiated,leading to significant clinical improvement.The patient successfully completed a 12-month course of TB therapy without recurrence or deterioration.CONCLUSION There are cases of TB wherein temporary improvement apparently could be shown through treatment with antimicrobial agents other than anti-TB drugs,necessitating careful evaluation in atypical cases of bacterial pneumonia.
基金Science and Technology Plan of Heilongjiang Provincial Health Commission,Study on the Efficacy of High-Throughput Real-Time Mass Spectrometry Detection of Exhaled Breath for Rapid Diagnosis of Pulmonary Tuberculosis(Project No.:20230303110014)。
文摘Objective:To evaluate the clinical efficacy of high-throughput real-time mass spectrometry detection technology for exhaled breath in the rapid diagnosis of pulmonary tuberculosis(PTB),providing a novel technological support for early screening and diagnosis of PTB.Methods:A total of 120 PTB patients admitted to a hospital from January 2023 to June 2024 were selected as the case group,and 150 healthy individuals and patients with non-tuberculous pulmonary diseases during the same period were selected as the control group.Exhaled breath samples were collected from all study subjects,and the types and concentrations of volatile organic compounds(VOCs)in the samples were detected using a high-throughput real-time mass spectrometer.A diagnostic model was constructed using machine learning algorithms,and core indicators such as diagnostic sensitivity,specificity,and area under the curve(AUC)of this technology were analyzed and compared with the efficacy of traditional sputum smear examination,sputum culture,and GeneXpert MTB/RIF detection.Results:The diagnostic sensitivity of the high-throughput real-time mass spectrometry diagnostic model for exhaled breath in diagnosing PTB was 92.5%,the specificity was 94.0%,and the AUC was 0.978,which were significantly higher than those of sputum smear examination(sensitivity 58.3%,specificity 90.0%,AUC 0.741).Compared with GeneXpert technology,its specificity was comparable(94.0%vs 93.3%),and the detection time was shortened to less than 15 minutes.The model achieved an accuracy of 91.3%in distinguishing PTB from other pulmonary diseases and was not affected by demographic factors such as age and gender.Conclusion:High-throughput real-time mass spectrometry detection technology for exhaled breath has the advantages of being non-invasive,rapid,highly sensitive,and highly specific,and holds significant clinical application value in the rapid diagnosis and large-scale screening of PTB,warranting further promotion.
文摘Introduction: Anti-tuberculosis drug resistance is a major problem in tuberculosis (TB) control programme, particularly multi-drug resistance TB (MDR-TB) in Nepal. Drug resistance is difficult to treat due to its associated cost and side effects. The objective of this study was to assess the drug resistance pattern and assess risk factor associated with MDR-TB among pulmonary tuberculosis patients attending National Tuberculosis Center. Methodology: The comparative cross sectional study was conducted at National Tuberculosis Center during August 2015 to February 2015. Early morning sputum samples were collected from pulmonary tuberculosis suspected patients and subjected to Ziehl-Neelsen staining and fluorochrome staining and culture on Lowenstein-Jensen (LJ) medium. Drug Susceptibility test was performed on culture positive isolates by using proportion method. Univariate and multivariate analysis was computed to assess the risk factors of MDR-TB. Results: Out of 223 sputum samples, 105 were fluorochrome staining positive, 85 were ZN staining positive and 102 were culture positive. Out of 102 culture positive isolates, 37.2% were resistance to any four anti-TB drugs. 11 (28.9%) were initial drug resistance and 28 (43.7%) were acquired drug resistance. The overall prevalence of MDR-TB was 11.7%, of which 2 (5.3%) were initial MDR-TB and 10 (15.6%) were acquired MDR-TB. Univariate and multivariate analysis showed female were significantly associated (P = 0.05) with MDR-TB. Conclusion: Drug resistance TB particularly MDR-TB is high. The most common resistance pattern observed in this study was resistance to both isoniazid and rifampicin. Female were found to be associated with MDR-TB. Thus, early diagnosis of TB and provision of culture and DST are crucial in order to combat the threat of DR-TB.

文摘BACKGROUND Pulmonary alveolar proteinosis(PAP)is a rare lung disease characterized by the accumulation of phospholipoproteinaceous material in the alveoli.Cases of PAP complicated with tuberculosis are much more complex and have rarely been well recorded.CASE SUMMARY We describe a 21-year-old Han Chinese patient with suspicious lung infection associated with mild restrictive ventilatory dysfunction and diffusion reduction.High resolution computed tomography revealed a“crazy-paving”appearance and multiple pulmonary miliary nodules around the bronchi.Bronchoalveolar lavage demonstrated a small amount of periodic acid-Schiff positive proteinaceous materials.A serological test for the presence of a Mycobacterium tuberculosis antibody and an interferon-gamma release assay were both positive.The patient received a standard course of first-line anti-tuberculosis treatment after diagnostic bronchoalveolar lavage.To date,clinical remission has been achieved and maintained for five years.CONCLUSION In summary,the diagnosis of PAP complicated with tuberculosis was supported by a combination of clinical manifestations,imaging,pulmonary function,laboratory examinations,bronchoalveolar lavage,etc.This case highlighted that diagnostic bronchoalveolar lavage in combination with anti-tuberculosis treatment is a safe and effective option for mild PAP patients with tuberculosis.
文摘Computed tomography(CT)examination is the major measure for detecting and diagnosis of foreign bodies in human body.Although CT has high sensitivity in diagnosis of foreign body,some interference factors may still lead to missed diagnosis or misdiagnosis.Here we report a rare case that a bamboo stick accidentally pierced into the left chest of a young man who was drunk and unware of this hurt.The patient experienced cough,chest pain,fever,hemoptysis,and was misdiagnosed as primary and secondary tuberculosis based on chest CT examinations at a local hospital,although no tubercular bacillus detected by sputum smear.He subsequently received anti-tuberculous treatments in the following three years,but no improvement of his symptoms was observed.Until one month before his death,the bamboo stick was detected by spiral CT examination as well as three-dimensional image reconstruction at another hospital.Postmortem examination revealed pneumonia,pulmonary infarction,and abscess as the causes of his death.We analyze the potential reasons of misdiagnosis in this case,aiming to provide reference for the diagnosis and treatment of pulmonary inflammation associated with foreign body in the future.

文摘BACKGROUND Organizing pneumonia secondary to pulmonary tuberculosis is rare.Moreover,the temporal boundary between pulmonary tuberculosis and secondary organizing pneumonia has not been defined.We report a case of secondary organizing pneumonia associated with pulmonary tuberculosis occurring after nine months of antituberculosis treatment.CASE SUMMARY A 54 years old man,previously diagnosed with pulmonary tuberculosis and tuberculous pleurisy,underwent nine months of antituberculosis treatment.Follow-up lung computed tomography revealed multiple new subpleural groundglass opacities in both lungs,and a lung biopsy confirmed organizing pneumonia.Treatment continued with anti-tuberculosis agents and hormone therapy,and subsequent dynamic pulmonary computed tomography exams demonstrated improvement in lesion absorption.No disease recurrence was observed after corticosteroid therapy discontinuation.CONCLUSION When treating patients with active pulmonary tuberculosis,if an increase in lesions is observed during anti-tuberculosis treatment,it is necessary to consider the possibility of tuberculosis-related secondary organizing pneumonia,timely lung biopsy is essential for early intervention.
文摘Objective. To evaluate the diagnosis and treatment for malignant gestational trophoblastic tumor(MGTT) with pulmonary metastasis complicated with pulmonary tuberculosis. Methods. To analyze ten cases of MGTT with pulmonary metastasis complicated with pulmonary tuberculosis in our hospital from 1980 to 1997 retrospectively. Results.From the x ray film, there are great resemblances between MGTT with pulmonary metastasis and pulmonary tuberculosis. Of 10 patients, 7 of them were examined out pulmonary tuberculosis during the chemotherapy of MGTT. Pulmonary tuberculosis appeared six months before chemotherapy in three cases. All of the patients were treated with multiagent chemotherapy. Seven patients achiceved a complete remission, 2 patients developed drug resistance and died of cerebral haemorrhage and cerebral herniation, 1 woman who had achieved a complete remission from MGTT for 14 months died of miliary tuberculosis. Conclusion. It is very important to make differential diagnosis of the MGTT with pulmonary metastasis complicated with pulmonary tuberculosis. Trying to avoid excessive anti tumor treatment owing to mistake pulmonary tuberculosis for pulmonary metastasis, and avoiding missing an opportunity of anti tuberculosis treatment because of missed diagnosis should be emphasized.
