Sample records for active pulmonary tuberculosis

  1. s-Findings of active pulmonary tuberculosis in computed tomography

    Purpose: Tuberculosis remains the most important infectious disease all over the world. We report on the CT findings of lung tuberculosis. Material and methods: Standardised retrospective analysis of the computed tomographic examinations in a total of 100 patients suffering from cultural or histological proven pulmonary tuberculosis. Results: The most common finding in our study group were micronodules and lobular opacities accompanied by enlarged lymph nodes. Cavitation and alteration of the bronchial system (esp. bronchial wall thickening) were found less common. The so-called tree- in bud-appearance which had been estimated by other authors to be rather characteristic for active pulmonary tuberculosis was seen in only 12/100 examinations. It is often found in cases showing severe bronchogenic spreading of the disease. Conclusion: The active pulmonary tuberculosis does not show any pathognomonic sign but the combination of findings as opacities and cavitation and segmental spreaded micronodules make the diagnosis probable. This holds also for the so-called tree- in-bud appearances which may be rather suggestive but is seen only in cases suffering from severe bronchiogenic propagation. (orig.)

  4. The usefulness of 99mTc-MIBI in the detection of active pulmonary tuberculosis

    The use of radiopharmaceuticals in evaluation of pulmonary tuberculosis may help to resolve difficult diagnostic problems such as discordance between sputum examinations and chest roentgenographic findings. We investigated the usefulness of 99mTc-methoxyisobutylisonitrile (MIBI) scintigraphy in the detection of active pulmonary tuberculosis. Forty-six patients with suspected active pulmonary tuberculosis were studied with sputum smear of AFB, sputum AFB culture, chest X-ray and MIBI scan. MIBI image was obtained 15 and 60 min after intravenous injection of 370MBq(10mCi) 99mTc-MIBI. In 16 patients of them Ga scans were performed in addition to MIBI scan. Repeated MIBI scans were done in 7 patients with active pulmonary tuberculosis after 4∼6 months of antituberculous chemotherapy. Thirty-two patients were confirmed as active tuberculosis by sputum culture. Sensitivity of MIBI scan to active tuberculosis was 87.5%(28/32) and MIBI findings were negative in all of 14 patients with inactive disease. Focal uptake of MIBI was dense in the area that was strongly suggested active tuberculous lesions by chest roentgenogram. There was no discordance between MIBI and Ga image in 16 patients. But the uptake areas of Ga images were broader than that of MIBI images. After 4∼6 months of antituberculous treatment all repeated MIBI scans revealed negative findings except 1 patient with persistent active pulmonary tuberculosis due to drug resistance. MIBI scan could be used in the detection of active pulmonary tuberculosis as a useful noninvasive diagnostic tool

    To evaluate the utility of high-resolution computed tomography (HRCT), as used to determine the activity of tuberculosis, and to analyze the HRCT findings in active and in inactive tuberculosis. We analyzed the HRCT findings of 100 patients (54 men, 46 women; average age, 54 years) who according to the results of chest radiography had pulmonary tuberculosis of undetermined activity. We assessed HRCT findings such as the presence of a centrilobular, macro-, or micronodule; consolidation, ground-glass opacity, cavity, interlobular septal thickening, irregular linear opacities, bronchial wall thickening, bronchovascular bundle distortion, bronchiectasis, atelectasis, and pericicatrical emphysema. We compared the ratio of the area of nodule and consolidation to that of whole lung, and compared the findings between active and inactive tuberculosis. Eleven of 100 patients were excluded because the final diagnosis was other than tuberculosis. In 59 patients, the presence of active pulmonary tuberculosis was proven by positive sputum smear and/or culture for mycobacterium tuberculosis. On the basis of the negative results of these tests, pulmonary tuberculosis was found to be inactive in 30 patients; serial chest radiographs indicated that their condition remained stable over a 6-month period. For HRCT, sensitivity was 96.6%, specificity 56.7%, positive predictive value 81.4%, negative predictive value 89.5%, and accuracy 83.1%. For active tuberculosis, the presence of centrilobular nodules, tree-in-bud, macronodules, cavity within the nodule, and consolidations was statistically significant, while for inactive tuberculosis, that of irregular linear opacities, micronodules, bronchiectasis, and cicatrization atectasis was similarly significant. The CT score for the area of nodules and consolidations was higher in active than in inactive tuberculosis, but only the nodule score showed statistical significance. HRCT can be a useful diagnostic tool for evaluating the activity

  8. Pulmonary tuberculosis

    Dissemination of the tubercle bacillus is of three types: bronchogenic, hematogenous, and lymphangitic. Bronchogenic dissemination occurs when exudate from a cavity or small area of caseation drains into a bronchus and is aspirated into previously uninfected areas either on the same or on the opposite side. This type of spreading occurs frequently after bleeding and when there is a cavity emptying into a bronchus. Hematogenous dissemination leads to miliary tuberculosis and to extrapulmonary lesions throughout the body. Acute massive hematogenous spread causes miliary tuberculosis, while chronic spread in smaller amounts usually results in the chronic extrapulmonary foci. Lymphangitic dissemination is common in primary infection. It is responsible for involvement with subsequent enlargement of hilar and mediastinal nodes that is often seen in children and in young black adults. The reaction to M. tuberculosis depends on the presence or absence of immunity to tuberculoprotein. In individuals having no tissue hypersensitivity or immunity, primary tuberculosis results. In those with immunity produced by previous infection or BCG vaccination, the reactivation (reinfection) disease may develop

  9. Comparison between 18F-FDG PET and CT in evaluating the activity of pulmonary tuberculosis

    Objective: To compare the difference between 18F-FDG PET and CT for evaluating the activity of pulmonary tuberculosis. Methods: 18F-FDG PET-CT was performed in 31 pulmonary tuberculosis patients,the activity of the tuberculosis lesions was evaluated by PET and CT images, the results of the two imaging methods were compared separately. Results: The results obtained with the two imaging methods were consistent in 26 cases and inconsistent in 5 cases.6 eases which CT diagnosed as inactive tuberculosis (healed lesions) were also judged as inactive lesions by PET imaging. In 16 cases, CT displayed that most of the lesions were calcified and associated with little streaks and diagnosed as inactive tuberculosis (obsolete lesions), among them PET judged 5 cases as active lesions, of which 3 cases with partly calcified lesion associated with mild radioactive uptake, 2 eases with streaks associated with mild radioactive uptake. 9 cases which CT diagnosed as active pulmonary tuberculosis, PET judged as active lesions too. Conclusions: 18FFDG PET and CT have the same judgment in diagnosing healed and active tuberculosis lesions, while 18FFDG PET is superior to CT in evaluating the active lesions residue in obsolete lesions.

  12. Loss of receptor on tuberculin-reactive T-cells marks active pulmonary tuberculosis.

    Mathias Streitz

    Full Text Available BACKGROUND: Tuberculin-specific T-cell responses have low diagnostic specificity in BCG vaccinated populations. While subunit-antigen (e.g. ESAT-6, CFP-10 based tests are useful for diagnosing latent tuberculosis infection, there is no reliable immunological test for active pulmonary tuberculosis. Notably, all existing immunological tuberculosis-tests are based on T-cell response size, whereas the diagnostic potential of T-cell response quality has never been explored. This includes surface marker expression and functionality of mycobacterial antigen specific T-cells. METHODOLOGY/PRINCIPAL FINDINGS: Flow-cytometry was used to examine over-night antigen-stimulated T-cells from tuberculosis patients and controls. Tuberculin and/or the relatively M. tuberculosis specific ESAT-6 protein were used as stimulants. A set of classic surface markers of T-cell naïve/memory differentiation was selected and IFN-gamma production was used to identify T-cells recognizing these antigens. The percentage of tuberculin-specific T-helper-cells lacking the surface receptor CD27, a state associated with advanced differentiation, varied considerably between individuals (from less than 5% to more than 95%. Healthy BCG vaccinated individuals had significantly fewer CD27-negative tuberculin-reactive CD4 T-cells than patients with smear and/or culture positive pulmonary tuberculosis, discriminating these groups with high sensitivity and specificity, whereas individuals with latent tuberculosis infection exhibited levels in between. CONCLUSIONS/SIGNIFICANCE: Smear and/or culture positive pulmonary tuberculosis can be diagnosed by a rapid and reliable immunological test based on the distribution of CD27 expression on peripheral blood tuberculin specific T-cells. This test works very well even in a BCG vaccinated population. It is simple and will be of great utility in situations where sputum specimens are difficult to obtain or sputum-smear is negative. It will also help

  13. We nuclear physicians might have used the term 'activity' of pulmonary tuberculosis differently from clinicians who treat patients with tuberculosis

    It is difficult to determine the activity of tuberculosis radiologically. Therefore there have been efforts to assess the activity using radiopharmaceuticals such as 67Ga, 99mTc-tetrofosmin, and 99mTc-MIBI. But there may be some discrepancy in difining the term 'activity' between clinicians and nuclear physicians. While negative conversion of sputum acid fast bacilli (AFB) is defined as 'disappearance of activity' by clinicians, a loss of uptake in previously positive lesion is accepted as 'disappearance of activity' by nuclear physicians. We designed a prospective study to see if the negative conversion of sputum AFB could directly match the disappearance of radioactivity of the lesion. Fifteen patients with bacteriologically confirmed active localized pulmonary tuberculosis were scanned 10 and 60 min after intravenous injection of 550 MBq 99mTc-MIBI. In 6 patients, who showed negative conversion of sputum AFB after 3-7 months of chemotherapy, 99mTc-MIBI scan was repeated. For the purpose of comparison, target/nontarget raitos of the lesions were determined. 12/15 (80%) patients with active pulmonary tuberculosis showed increased uptake of 99mTc-MIBI in tuberculous lesion. After negative conversion of sputum AFB, 5/6 (83%) patients still showed increased uptake, although the intensity of uptake decreased. Uptake of radioactivity decreased but did not disappear after negative conversion of sputum AFB. 99mTc-MIBI scan may be useful to address the degree of inflammation of pulmonary tuberculous lesion, but the uptake did not directly match the activity defined by positivity of sputum AFB. We nuclear physicians might have used the term 'activity' somewhat differently from clinicians who treat patients with tuberculosis

  14. Imaging of pulmonary tuberculosis

    Tuberculosis, more than any other infectious disease, has always been a challenge, since it has been responsible for a great amount of morbidity and mortality in humans. After a steady decline in the number of new cases during the twentieth century, due to improved social and environmental conditions, early diagnosis, and the development of antituberculous medication, a stagnation and even an increase in the number of new cases was noted in the mid-1980s. The epidemiological alteration is multifactorial: global increase in developing countries; minority groups (HIV and other immunocompromised patients); and elderly patients due to an altered immune status. Other factors that may be responsible are a delayed diagnosis, especially in elderly patients, incomplete or inadequate therapy, and the emergence of multidrug-resistant tuberculosis. The course of the disease and its corresponding clinicoradiological pattern depends on the interaction between the organism and the host response. Classically, pulmonary tuberculosis has been classified in primary tuberculosis, which occurred previously in children, and postprimary tuberculosis, occurring in adult patients. In industrialized countries, however, there seems to be a shift of primary tuberculosis towards adults. Furthermore, due to an altered immunological response in certain groups, such as immunocompromised and elderly patients, an atypical radioclinical pattern may occur. The changing landscape, in which tuberculosis occurs, as well as the global resurgence, and the changed spectrum of the clinical and radiological presentation, justify a renewed interest of radiologists for the imaging features of pulmonary tuberculosis. This article deals with the usual imaging features of pulmonary tuberculosis as well as the atypical patterns encountered in immunodepressed and elderly patients. (orig.)

    2002-01-01

    Background: The prevalence of tuberculosis in adult men in India is 2–4 times higher than in women. Tobacco smoking is prevalent almost exclusively among men, so it is possible that tobacco smoking may be a risk factor for developing pulmonary tuberculosis. A nested case control study was carried out to study the association between tobacco smoking and pulmonary tuberculosis.

  17. Pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis

    Objectives: Patients with idiopathic pulmonary fibrosis (IPF) have an increased risk of pulmonary tuberculosis. However, detecting pulmonary tuberculosis may be difficult due to the underlying fibrosis. The aim of this report is to describe the radiological and clinical findings of pulmonary tuberculosis in patients with idiopathic pulmonary fibrosis. Materials and methods: We reviewed 143 consecutive patients in whom IPF was diagnosed by either the histological or radio-clinical criteria. Among them, nine patients were histologically (n=2) or bacteriologically (n=7) confirmed to have active pulmonary tuberculosis. The location and patterns of pulmonary tuberculosis were examined on a thin section CT scan. Results: The most common thin section CT findings were subpleural nodules (n=6; mean diameter, 3.2 cm) and a lobar or segmental consolidation (n=3). The lesions were located most commonly in the right lower lobe (n=4). The incidence of tuberculosis in patients with idiopathic pulmonary fibrosis was more than five times higher than that of the general population. Conclusion: The atypical manifestation of pulmonary tuberculosis is common in patients with idiopathic pulmonary fibrosis, which may mimic lung cancer or bacterial pneumonia

  19. Pediatric postprimary pulmonary tuberculosis

    Heading AbstractBackground. Postprimary pulmonary tuberculosis (TB) is not commonly seen in children.Objective. The purpose of this study was to determine the radiographic findings and patient characteristics of pediatric postprimary pulmonary TB.Materials and methods. We reviewed the clinical charts and chest radiographs in six patients.Results. The radiographic findings of pediatric postprimary pulmonary TB include upper-lobe consolidation and cavitation, multifocal ill-defined airspace opacities, evidence of prior pulmonary TB, and apical pleural thickening. Pleural effusions and lymphadenopathy are not commonly present. Although postprimary disease typically does not affect young children, five of the children in this series were less than ten years of age at the time of presentation.Conclusion The possibility of postprimary TB should be considered in pediatric patients at risk for this disease who present with upper-lobe pulmonary consolidation and cavitation. These patients are highly infectious and early recognition and treatment can limit transmission of TB. (orig.)

    Background/Aims: The objective of this prospective study was to evaluate the diagnosis and treatment of latent tuberculosis infection (LTBI) in adult close contacts of active pulmonary tuberculosis (TB) patients in Korea. Methods: Adult close contacts of active pulmonary TB patients were recruited at a regional tertiary hospital in Korea. The participants were tested for LTBI using the tuberculin skin test (TST) and/or QuantiFERON-TB Gold (QFT-G) test. LTBI patients, who consented to treatment, were randomly assigned to receive isoniazid for 9 months (9INH) or rifampin for 4 months (4RIF). Results: We examined 189 adult close contacts (> 18 years) of 107 active pulmonary TB patients. The TST and QFT-G were positive (≥ 10 mm) in 75/183 (39.7%) and 45/118 (38.1%) tested participants, respectively. Among 88 TST or QFT-G positive LTBI participants, 45 participants were randomly assigned to receive 4RIF (n = 21) or 9INH (n = 24), respectively. The average treatment duration for the 4RIF and 9INH groups was 3.3 ± 1.3 and 6.1 ± 2.7 months, respectively. Treatment was completed in 25 participants (4RIF, n = 16; 9INH, n = 9). LTBI participants who accepted treatment were more likely to be women and have more cavitary lesions on the chest radiographs of index cases and positive TST and QFT-G results compared to those who refused treatment. Conclusions: About 40% of adult close contacts of active pulmonary TB patients had LTBI; about 50% of these LTBI participants agreed to treatment. PMID:27052266

    1987-01-01

    The incidence of reactive thrombocytosis in active pulmonary tuberculosis was studied in 122 patients. Thrombocytosis was common, platelet counts often exceeding 1 X 10(12)/1. A significant inverse correlation was noted between the mean platelet volume and the platelet count (r = -0.54, p less than 0.0001). Interval estimation suggested that this relation was non-linear. Further studies were done in a small group of six patients. Platelet survival was considerably shortened, the platelets agg...

  4. Coincident helminth infection modulates systemic inflammation and immune activation in active pulmonary tuberculosis.

    Parakkal Jovvian George

    Full Text Available Helminth infections are known to modulate innate and adaptive immune responses in active and latent tuberculosis (TB. However, the role of helminth infections in modulating responses associated with inflammation and immune activation (reflecting disease activity and/or severity in TB is not known.We measured markers of inflammation and immune activation in active pulmonary TB individuals (ATB with co-incidental Strongyloides stercoralis (Ss infection. These included systemic levels of acute phase proteins, matrix metalloproteinases and their endogenous inhibitors and immune activation markers. As a control, we measured the systemic levels of the same molecules in TB-uninfected individuals (NTB with or without Ss infection.Our data confirm that ATB is associated with elevated levels of the various measured molecules when compared to those seen in NTB. Our data also reveal that co-incident Ss infection in ATB individuals is associated with significantly decreased circulating levels of acute phase proteins, matrix metalloproteinases, tissue inhibitors of matrix metalloproteinases as well as the systemic immune activation markers, sCD14 and sCD163. These changes are specific to ATB since they are absent in NTB individuals with Ss infection.Our data therefore reveal a profound effect of Ss infection on the markers associated with TB disease activity and severity and indicate that co-incidental helminth infections might dampen the severity of TB disease.

  5. Inflammasome genetics contributes to the development and control of active pulmonary tuberculosis.

    Souza de Lima, D; Ogusku, M M; Sadahiro, A; Pontillo, A

    2016-07-01

    Tuberculosis (TB) continues to be a major public health problem. An estimated one-third of the world's population is infected with Mycobacterium tuberculosis (Mtb) but remains asymptomatic (latent TB) and only 5% to 10% of these latent individuals will develop active pulmonary TB. Factors affecting the balance between latent and active TB are mostly unknown, even if host genome has been shown to contribute to the outcome of Mtb response. Acute inflammation and Th1 response are important in the early clearance of the bacteria as it was emphasized by the association between immune genes (i.e.: HLA, IFNG, TNF, NRPAM1, IL10) variants and the development of active pulmonary TB. Recently, the role of the inflammasome in experimental TB has been demonstrated, however, to our knowledge, no data still exist about the contribution of inflammasome genetics to Mtb susceptibility and/or to the development of active TB. For this reason, selected polymorphisms in inflammasome genes were analysed in a case/control cohort of individuals with active pulmonary TB from an endemic area of Brazil Amazon. Our data evidence the novel association between polymorphisms in NLRP3-inflammasome encoding genes and active pulmonary TB, and replicated the association between P2X7 and TB observed in other populations. These results emphasize the role of NLRP3-inflammasome also in human TB, and contribute to our knowledge about pathways involved in the development of active TB, even if deeper investigation are needed to fully elucidate the role of the complex in Mtb infection.

  6. Comparison of sensitivity of quantiferon-tb gold test and tuberculin skin test in active pulmonary tuberculosis

    Objective: To compare the sensitivity of tuberculin skin test (TST) and quantiFERON-TB gold test (QFT-G) in active pulmonary tuberculosis. Study Design: Analytical study. Place and Duration of Study: Department of Pulmonology, Fauji Foundation Hospital, Rawalpindi, from July 2011 to January 2012. Methodology: QuantiFERON-TB gold test (QFT-G) was evaluated and compared it with tuberculin skin test (TST) in 50 cases of active pulmonary tuberculosis, in whom tuberculous infection was suspected on clinical, radiological and microbiological grounds. Sensitivity was determined against positive growth for Mycobacterium tuberculosis. Results: Out of 50 cases, 43 were females and 7 were males. The mean age was 41.84 A+- 19.03 years. Sensitivity of QFT-G was 80% while that of TST was 28%. Conclusion: QFT-G has much higher sensitivity than TST for active pulmonary tuberculosis. It is unaffected by prior BCG administration and prior exposure to atypical mycobacteria. A positive QFT-G result can be an adjunct to diagnosis in patients having clinical and radiological data compatible with pulmonary tuberculosis. (author)

  7. High-resolution CT for identify patients with smear-positive, active pulmonary tuberculosis

    Purpose: This study evaluates the use of high-resolution computed tomography (HRCT) to differentiate smear-positive, active pulmonary tuberculosis (PTB) from other pulmonary infections in the emergency room (ER) setting. Methods: One hundred and eighty-three patients diagnosed with pulmonary infections in an ER were divided into an acid fast bacillus (AFB) smear-positive, active PTB group (G1 = 84) and a non-AFB smear-positive, pulmonary infection group (G2 = 99). HRCT images from a 64-Multidetector CT were analyzed, retrospectively, for the morphology, number, and segmental distribution of pulmonary lesions. Results: Utilizing multivariate analysis, five variables were found to be independent risk factors predictive of G1: (1) consolidation involving the apex segment of right upper lobe, posterior segment of the right upper lobe, or apico-posterior segment of the left upper lobe; (2) consolidation involving the superior segment of the right or left lower lobe; (3) presence of a cavitary lesion; (4) presence of clusters of nodules; (5) absence of centrilobular nodules. A G1 prediction score was generated based on these 5 criteria to help differentiate G1 from G2. The area under the receiver operating characteristic (ROC) curve was 0.96 ± 0.012 in our prediction model. With an ideal cut-off point score of 3, the specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV) are 90.9%, 96.4%, 90.0% and 96.8%, respectively. Conclusion: The use of this AFB smear-positive, active PTB prediction model based on 5 key HRCT findings may help ER physicians determine whether or not isolation is required while awaiting serial sputum smear results in high risk patients.

  10. Radioiodine uptake in inactive pulmonary tuberculosis

    Radioiodine may accumulate at sites of inflammation or infection. We have seen such accumulation in six thyroid cancer patients with a history of previously treated pulmonary tuberculosis. We also review the causes of false-positive radioiodine uptake in lung infection/inflammation. Eight foci of radioiodine uptake were seen on six iodine-123 diagnostic scans. In three foci, the uptake was focal and indistinguishable from thyroid cancer pulmonary metastases from thyroid cancer. In the remaining foci, the uptake appeared nonsegmental, linear or lobar, suggesting a false-positive finding. The uptake was unchanged, variable in appearance or non-persistent on follow-up scans and less extensive than the fibrocystic changes seen on chest radiographs. In the two patients studied, thyroid hormone level did not affect the radioiodine lung uptake and there was congruent gallium-67 uptake. None of the patients had any evidence of thyroid cancer recurrence or of reactivation of tuberculosis and only two patients had chronic intermittent chest symptoms. Severe bronchiectasis, active tuberculosis, acute bronchitis, respiratory bronchiolitis, rheumatoid arthritis-associated lung disease and fungal infection such as Allescheria boydii and aspergillosis can lead to different patterns of radioiodine chest uptake mimicking pulmonary metastases. Pulmonary scarring secondary to tuberculosis may predispose to localized radioiodine accumulation even in the absence of clinically evident active infection. False-positive radioiodine uptake due to pulmonary infection/inflammation should be considered in thyroid cancer patients prior to the diagnosis of pulmonary metastases. (orig.)

    2007-03-01

    Full Text Available Abstract Background Assuming a higher risk of latent tuberculosis (TB infection in the population of Rio de Janeiro, Brazil, in October of 1998 the TB Control Program of Clementino Fraga Filho Hospital (CFFH routinely started to recommend a two-step tuberculin skin test (TST in contacts of pulmonary TB cases in order to distinguish a boosting reaction due to a recall of delayed hypersensitivity previously established by infection with Mycobacterium tuberculosis (M.tb or BCG vaccination from a tuberculin conversion. The aim of this study was to assess the prevalence of boosted tuberculin skin tests among contacts of individuals with active pulmonary tuberculosis (TB. Methods Retrospective cohort of TB contacts ≥ 12 years old who were evaluated between October 1st, 1998 and October 31st 2001. Contacts with an initial TST ≤ 4 mm were considered negative and had a second TST applied after 7–14 days. Boosting reaction was defined as a second TST ≥ 10 mm with an increase in induration ≥ 6 mm related to the first TST. All contacts with either a positive initial or repeat TST had a chest x-ray to rule out active TB disease, and initially positive contacts were offered isoniazid preventive therapy. Contacts that boosted did not receive treatment for latent TB infection and were followed for 24 months to monitor the development of TB. Statistical analysis of dichotomous variables was performed using Chi-square test. Differences were considered significant at a p Results Fifty four percent (572/1060 of contacts had an initial negative TST and 79% of them (455/572 had a second TST. Boosting was identified in 6% (28/455. The mean age of contacts with a boosting reaction was 42.3 ± 21.1 and with no boosting was 28.7 ± 21.7 (p = 0.01. Fifty percent (14/28 of individuals whose test boosted met criteria for TST conversion on the second TST (increase in induration ≥ 10 mm. None of the 28 contacts whose reaction boosted developed TB disease within

  12. The pattern of active pulmonary tuberculosis in adults at King Hussein Medical Center, Jordan

    To identify the pattern of the clinical, radiological, and diagnostic procedures of the diagnosed cases of active pulmonary tuberculosis (TB) patients presented to the Respiratory Medicine Division at King Hussein Medical Center over the last 10 years. This is a retrospective analysis of the medical records and chest radiographs of 137 active pulmonary TB patients who were diagnosed between March 1995 and October 2005. Patient's symptoms were recorded and analyzed. Radiological findings were assessed. Procedures used to identify Mycobacterium TB were identified. One hundred and thirty-seven patients medical records were retrieved and analyzed (84 males and 53 females). The mean age (range) was 48.43 +/- 14.65 (14-83) years. The most common presenting symptoms were cough (79%), weight loss (74%), and fatigue (69%). Other presenting complaints were fever (69%), excessive night sweating (55%), chest pain (41%) and dyspnea (39%). Thirty-one percent of the cohort presented with hemoptysis. Seventy-one patients had different types of opacities and infiltrates in their chest x-ray. Micro- or macro- nodular lung changes were reported in 22 (16%) patients. Lung cavitations and pleural effusions were present in 13% of the studied patients. In 7% of cases, bronchiectasis was noted as a sequelae of long-standing lung disease. The right lung was involved in 51% of cases; the left lung in 27% and bilateral lung involvement was noted in 22% of patients. The upper lobes were involved in 63%. Sputum for acid-fast bacilli (AFB) Z-Nielson stain and culture was positive in 51%, bronchial wash was positive in 27% of cases. The diagnosis was made by histopathological examination in 15% of cases. This study showed that active pulmonary TB patients vary in clinical presentation. The radiological manifestations of pulmonary TB are heterogeneous. Sputum for AFB remains an important, easy and inexpensive measure for TB diagnosis, but may not be always helpful in early diagnosis. Bronchoscopy

  13. Chest radiography and thoracic computed tomography findings in children who have family members with active pulmonary tuberculosis

    Objective: The chest radiography and TCT findings in children who had contacted with adult family members with active pulmonary tuberculosis were compared. The contributions of thoracic computed tomography to the diagnosis of tuberculosis were investigated. Methods and material: The children who were 0-16 years old (n=173) and children of families with an adult member which was diagnosed as pulmonary tuberculosis were evaluated. The children were considered in two groups based on the absence (n=125) or presence (n=48) of complaints and/or ambiguous symptoms such as lack of appetite, mild cough, sweating, history of lung infection, low body weight and those with suspicious chest radiography findings (12 cases) were included in this study. Asymptomatic patients (n=125) did not undergo TCT. Patients who had positive PPD skin tests only received isoniazid. If the TCT demonstrated enlarged lymph nodes or parenchymal lesions, minimally active pulmonary tuberculosis was diagnosed and antituberculous treatment was given. Results and discussions: TCT revealed lymph node enlargement or parenchymal lesions in 39 children (81.2%). Of the 12 children whose CXRs revealed suspicious lymph node enlargement and/or infiltration, five had normal findings in TCT whereas the initial findings were confirmed in the remaining seven. These data suggest that there is a correlation between the presence of ambiguous symptoms in exposed children and TCT findings; chest radiography and TCT findings do not yield parallel findings. All the patients who received anti-TB treatment were resolved in the control examinations. Conclusion: In this study there is a correlation between presence of ambiguous symptoms and TCT findings, but the chest radiography and TCT findings do not yield harmony in exposed children with ambiguous symptoms (suspicious tuberculosis cases). These observations should be considered in children with symptoms similar to those of exposed children, but with no definite history of

    Highlights: • Digital tomosynthesis and dual energy subtraction digital radiography are modifications of digital radiography. • These modalities perform better than digital radiography in detection of parenchymal lesions in active pulmonary tuberculosis. • Digital tomosynthesis has a sensitivity of 100% in detection of cavities. • Centrilobular nodules seen on CT in active pulmonary tuberculosis, were also demonstrated on digital tomosynthesis in our study. • Digital tomosynthesis can be used for diagnosis and follow up of patients in pulmonary tuberculosis, thereby reducing the number of CT examinations. - Abstract: Objective: To assess the role of digital tomosynthesis (DTS) and dual energy subtraction digital radiography (DES-DR) in detection of parenchymal lesions in active pulmonary tuberculosis (TB) and to compare them with digital radiography (DR). Materials and methods: This prospective study was approved by our institutional review committee. DTS and DES-DR were performed in 62 patients with active pulmonary TB within one week of multidetector computed tomography (MDCT) study. Findings of active pulmonary TB, that is consolidation, cavitation and nodules were noted on digital radiography (DR), DTS and DES-DR in all patients. Sensitivity, specificity, positive and negative predictive values of all 3 modalities was calculated with MDCT as reference standard. In addition presence of centrilobular nodules was also noted on DTS. Results: Our study comprised of 62 patients (33 males, 29 females with age range 18–82 years). Sensitivity and specificity of DTS for detection of nodules and cavitation was better than DR and DES-DR. Sensitivity and specificity of DTS for detection of consolidation was comparable to DR and DES-DR. DES-DR performed better than DR in detection of nodules and cavitation. DTS was also able to detect centrilobular nodules with sensitivity and specificity of 57.4% and 86.5% respectively. Conclusion: DTS and DES-DR perform better

    Moxifloxacin is the most active fluoroquinolone against Mycobacterium tuberculosis in vitro. However, data about the efficacy in patients are not available. We enrolled 17 patients with tuberculosis in a prospective, randomized study. After 5 days of monotherapy with either moxifloxacin or isoniazid, we detected significant decreases in mean CFU per milliliter in sputum in both groups. The calculated early bactericidal activities for isoniazid and moxifloxacin were 0.209 and 0.273 log10 CFU p...

  19. IL-10 dependent suppression of type 1, type 2 and type 17 cytokines in active pulmonary tuberculosis.

    Nathella Pavan Kumar

    Full Text Available BACKGROUND: Although Type 1 cytokine responses are considered protective in pulmonary tuberculosis (PTB, their role as well as those of Type 2, 17 and immunoregulatory cytokines in tuberculous lymphadenitis (TBL and latent tuberculosis (LTB have not been well studied. AIM AND METHODS: To identify cytokine responses associated with pulmonary tuberculosis (TB, TB lymphadenitits and latent TB, we examined mycobacterial antigen-specific immune responses of PTB, TBL and LTB individuals. More specifically, we examined ESAT-6 and CFP-10 induced Type 1, Type 2 and Type 17 cytokine production and their regulation using multiplex ELISA. RESULTS: PTB individuals exhibited a significantly lower baseline as well as antigen-specific production of Type 1 (IFNγ, TNFα and IL-2; Type 2 (IL-4 and Type 17 (IL-17A and IL-17F cytokines in comparison to both TBL and LTB individuals. TBL individuals exhibited significantly lower antigen-specific IFNγ responses alone in comparison to LTB individuals. Although, IL-10 levels were not significantly higher, neutralization of IL-10 during antigen stimulation resulted in significantly enhanced production of IFNγ, IL-4 and IL-17A in PTB individuals, indicating that IL-10 mediates (at least partially the suppression of cytokine responses in PTB. CONCLUSION: Pulmonary TB is characterized by an IL-10 dependent antigen-specific suppression of Type 1, Type 2 and Type 17 cytokines, reflecting an important association of these cytokines in the pathogenesis of active TB.

    Full Text Available Background: A rapid, technically non-demanding and inexpensive diagnostic test is needed to improve the early detection and better management of active pulmonary tuberculosis especially in resource limited areas. Objective: To assess the diagnostic value and usefulness of the commercially available MycoDotTM (DynaGen Inc., Cambridge, MA, USA in the diagnosis of active pulmonary tuberculosis in Nepalese population. Materials and Methods: A prospective study was done from January 2008 to August 2008 on a group of 120 sputum smear positive adult patient group aged 17 to 78 years, confirmed cases of active pulmonary tuberculosis (with TB were enrolled and sera samples collected from them. The second group comprised of 105 healthy controls with no history of pulmonary tuberculosis (without TB and sera samples collected from them. The MycoDotTM serologic test was done on the sera samples collected from both the study groups according to the manufacturer’s instructions. Results: Of the sera collected from 120 sputum smear positive cases (with TB group, 48 sera specimens were MycoDotTM test positive (sensitivity = 40%; 95% CI 31.68–48.94. Healthy controls (without-TB group – 8 sera samples were found to be positive by the MycoDotTM test and the remaining 97 sera samples tested negative by this serologic test (specificity = 92.38%; 95% CI 85.68–96.09. The value for % false positive was 7.61% and for % false negative was 60%. The positive predictive value and the negative predictive value was 85.71% (95% CI 73.22–93.20 and 57.4% (95% CI 49.56–64.88, respectively. Conclusion: The MycoDotTM test with its rapidity (completed within 20 min, easy – to – perform format and no expensive instrumentation required – had high specificity but a relatively low sensitivity in the study group subjects and thus could be used only as an additional test in the diagnosis of active pulmonary tuberculosis and to be interpreted judiciously alongwith clinical

    Tc-99m ciprofloxacin is available for imaging infection. However, there has been no study on employing single photon emission computed tomography (SPECT) with using Tc-99m ciprofloxacin to image active pulmonary tuberculosis. Therefore, we conducted this study to assess the efficacy of Tc-99m ciprofloxacin SPECT for imaging active pulmonary tuberculosis. Twenty-one participants were enrolled in this prospective study. They were divided into two groups according to the clinical and radiological assessment. Group one (Gr. 1) consisted of five normal volunteers and six patients with inactive pulmonary tuberculosis. Group two (Gr. 2) consisted of ten patients with active pulmonary tuberculosis. SPECT was performed 3 h after injecting 555 MBq (15 mCi) of Tc-99m ciprofloxacin. The findings of Tc-99m ciprofloxacin SPECT were interpreted by a nuclear medicine specialist and then the results were analyzed according to the patients' clinical and radiological classifications. The results of Tc-99m ciprofloxacin SPECT were as follows: eight true-positive cases, ten true-negative cases, one false-positive case and two false-negative cases. The sensitivity and specificity was 80.0% and 90.0%, respectively. The positive predictive value was 88.9% and the negative predictive value was 83.3%. Conclusions Tc-99m ciprofloxacin SPECT is feasible for imaging active pulmonary tuberculosis. It is a useful nuclear-imaging method for discriminating between the active and inactive tuberculosis states in patients with a past medical history of pulmonary tuberculosis.

  4. Cytotoxic Activity of Dendritic Cells as a Possible Mechanism of Negative Regulation of T Lymphocytes in Pulmonary Tuberculosis

    Ludmila V. Sakhno

    2012-01-01

    Full Text Available The PD-1/B7-H1-mediated induction of T cell apoptosis/anergy as a possible mechanism of immune response failure was studied in 76 patients with pulmonary tuberculosis (TB with normal and low-proliferative response to antigens of M. tuberculosis (purified protein derivative (PPD. It was revealed that dendritic cells (DCs, generated in vitro from patient blood monocytes with GM-CSF + IFN-α, were characterized by increased B7-H1 expression, upproduction of IL-10, and reducing of allostimulatory activity in mixed lymphocyte culture (MLC. Moreover, DCs of patients with TB were able to enhance T cell apoptosis and to block T-cell division in MLC. It was shown that neutralizing anti-PD1 antibodies significantly decreased the proapoptogenic/tolerogenic effect of DCs. Correlation analysis revealed a direct relationship between IL-10 production and level of B7-H1 expression in the general group of investigated patients. It was demonstrated that generation of healthy donor DCs in the presence of IL-10 led to an increase in the number of DCs-expressed B7-H1 molecule, DC proapoptogenic activity, and a decrease in their allostimulatory activity. Obviously, the revealed phenomenon of the PD-1/B7-H1-mediated pro-apoptogenic activity of DCs is clinically significant since the cytotoxic/tolerogenic potential of DCs is more pronounced in patients with PPD anergy.

  7. Serial counts of Mycobacterium tuberculosis in sputum as surrogate markers of the sterilising activity of rifampicin and pyrazinamide in treating pulmonary tuberculosis

    Mitchison Denis

    2001-11-01

    Full Text Available Abstract Background Since the sterilising activity of new antituberculosis drugs is difficult to assess by conventional phase III studies, surrogate methods related to eventual relapse rates are required. Methods A suitable method is suggested by a retrospective analysis of viable counts of Mycobacterium tuberculosis in 12-hr sputum collections from 122 newly diagnosed patients with pulmonary tuberculosis in Nairobi, done pretreatment and at 2, 7, 14 and 28 days. Treatment was with isoniazid and streptomycin, supplemented with either thiacetazone (SHT or rifampicin + pyrazinamide (SHRZ. Results During days 0–2, a large kill due to isoniazid occurred, unrelated to treatment or HIV status; thereafter it decreased exponentially. SHRZ appeared to have greater sterilising activity than SHT during days 2–7 (p = 0.044, due to rifampicin, and during days 14–28, probably due mainly to pyrazinamide. The greatest discrimination between SHRZ and SHT treatments was found between regression estimates of kill over days 2–28 (p = 0.0005 in patients who remained positive up to 28 days with homogeneous kill rates. No associations were found between regression estimates and the age, sex, and extent of disease or cavitation. An increased kill in HIV seropositive patients, unrelated to the treatment effect, was evident during days 2–28 (p = 0.007, mainly during days 2–7. Conclusions Surrogate marker studies should either be in small groups treated with monotherapy during days 2 to about 7 or as add-ons or replacements in isoniazid-containing standard regimens from days 2 to 28 in large groups.

Although classical microbiological methods (such as sputum smear are specific, they have little sensitivity and the culture is also time-consuming. Using Polymerase Chain Reaction (PCR in blood samples in terms of Mycobacterium tuberculosis DNA, this study examines diagnostic power of this test in the diagnosis of pulmonary tuberculosis compared with other standard methods. Materials and Methods: In a cross-sectional descriptive-analytic study, blood samples were taken from 40 TB patients and 40 non-TB cases. Following DNA extraction by the commercial kit QIAGEN, the PCR assay was performed using IS6110 primer.Results: In this study, there were 80 people in two groups of TB and non-TB cases. Each group composed of 14 men (35% and 26 women (65%. Sensitivity, specificity as well as positive and negative predictive values obtained 37.5, 100, 100 and 61.5%, respectively.Conclusion: Despite high costs of using PCR for TB diagnosis, sensitivity of this method is low due to various factors and cannot replace current standard methods for TB diagnosis such as smear and culture. It can only be used as a complementary method to confirm diagnosis in strongly suspected cases of tuberculosis.

  10. Pulmonary Immune-Compartment-Specific Interferon Gamma Responses in HIV-Infected Individuals with Active Tuberculosis (TB in an Area of High TB Prevalence

    S. Buldeo

    2012-01-01

    Full Text Available There is a paucity of data on the pulmonary immune-compartment interferon gamma (IFNγ response to M. tuberculosis, particularly in settings of high tuberculosis (TB prevalence and in HIV-coinfected individuals. This data is necessary to understand the diagnostic potential of commercially available interferon gamma release assays (IGRAs in both the pulmonary immune-compartment and peripheral blood. We used intracellular cytokine staining by flow cytometry to assess the IFNγ response to purified protein derivative (PPD and early secretory antigen 6 (ESAT6 in induced sputa (ISp and blood samples from HIV-infected, smear-negative, TB suspects. We found that individuals with active TB disease produced significantly less IFNγ in response to PPD in their induced sputa samples than individuals with non-active TB (control group. This difference was not reflected in the peripheral blood, even within the CD27− CD4+ memory T lymphocyte population. These findings suggest that progression to active TB disease may be associated with the loss of IFNγ secretion at the site of primary infection. Our findings highlight the importance of studying pulmonary immune-compartment M. tuberculosis specific responses to elucidate IFNγ secretion across the spectrum of TB disease.

    with the active disease, such as centrilobular nodules segmentarily distributed, thick-walled cavities, thickened bronchial or bronchiolar walls, bronchiectasis and lymphadenopathy can be observed by computerized tomography. Thin-walled cavities, traction bronchiectasis, parenchymal bands, emphysema and mosaic pattern are signs suggestive of inactive disease. Gallium-67 citrate scyntigraphy is a complementary method useful in the detection of infectious diseases, including tuberculosis, especially in immunocompromised patients. Inhalation / perfusion analyses are used in the pre-operative assessment of patients carrying tuberculosis sequelaes and multiresistant tuberculosis. Positron emission tomography with fluorine-18 labeled deoxyglucose allows the detection of the inflammatory process that takes place during the active stage of tuberculosis and may persist, not so intense, after specific treatment is over. Imaging methods are valuable tools to be used in the diagnosis and follow up of pulmonary tuberculosis.

  14. Predictors of radiological sequelae of pulmonary tuberculosis

    In patients with pulmonary tuberculosis, clinical factors that are associated with poor radiological outcome have not been adequately addressed in the medical literature. The aim of this study was to explore some of these factors in patients admitted to a large chest hospital in Saudi Arabia with pulmonary tuberculosis. Material and Methods: Chest radiographs of 1080 patients with pulmonary tuberculosis were reviewed. Post-treatment residual changes were classified from 1 to 5 according to the severity of these changes. Data analysis was done by tabulating these classes against different variables that were likely to influence the final radiological appearance at the end of the treatment period. Results: Near-complete or complete clearance of chest radiography (Class 1) was seen in 43.5% of patients 40 years old (p8 weeks). Chest radiography clearance was more frequent (51.6%) in patients with good compliance with drug therapy compared to those with poor compliance (18.8%). Persistent cavitation (Class 5) was seen in 30.4% of cases with a past history of tuberculosis and in only 14% of cases with no such history. Conclusion: Old age, female gender, long duration of symptoms (delayed diagnosis), poor compliance with treatment and positive history of tuberculosis were associated with poor radiological outcome

  16. Cavitary pulmonary tuberculosis HIV-related

    Introduction: It was usually assumed that pulmonary tuberculosis (TB) in HIV-seropositive patients represents reactivation TB, despite the radiographic appearance frequently consistent rather with a recent disease. Hence, these radiographic features were considered 'atypical'. We have hypothesised that the so called 'atypical' radiographic features could be due to a greater proportion of primary TB among these patients, representing the typical appearance of primary radiological pattern. Material and methods: We reviewed chest imaging of 219 HIV+ patients with microbiological proven pulmonary tuberculosis, who were assessed for the presence, number, distribution of cavitations and for associated pulmonary parenchymal abnormalities, adenopathies and pleural effusion, and were classified as a primary or post-primary pattern. Results: The patients with post-primary pattern were 50%, and the rate of cavitation was 63%, not wandering off the general population. Cavities still occurred with similar proportion in groups with CD4 200 cells/mm3. Conclusion: We suggest that HIV-related pulmonary tuberculosis is typical in its radiological appearances, consistent with those of the general population, and this could be confirmed by the most recent molecular epidemiological techniques that allow to definitely classify the tuberculosis episodes as either primary or post-primary disease

  17. [Management of respiratory failure in patients with pulmonary tuberculosis].

    The prognosis is very poor in patients with acute respiratory failure (ARF) due to active pulmonary tuberculosis, especially in those who necessitate mechanical ventilation. The underlining factors of ARF are low nutrition, old age and severity because of patient's delay and doctor's delay. So, management consists of two parts, one, early patient detection considering of tuberculosis and early treatment, the other, focused control to high risk groups. Patients with chronic respiratory failure due to pulmonary tuberculosis sequelae have long insidious period and mainly restrictive, sometimes mixed pulmonary dysfunction. Hypercapnea, pulmonary hypertension and respiratory disorder during sleep are seen in high percentage in them. In acute on chronic failure the principles of therapy are treatment of precipitating factors such as respiratory infection or congestive heart failure, controlled (low flow) oxygen therapy, bronchial hygiene and maintaining adequate pulmonary and circulatory condition. In chronic stage patient education is very important. Management of chronic stage is constructed of nutrition control, long-term oxygen therapy, pharmacological therapy, pulmonary rehabilitation including controlled breathing technique, physical chest therapy and exercise training. Noninvasive positive pressure ventilation is effective on improvement of prognosis in chronic respiratory failure, and on treatment in acute on chronic failure. PMID:12664448

    Conclusions: The prevalence of HIV seropositivity among pulmonary and extra pulmonary TB in the present study was 6.38%. Tuberculosis was associated with an increased incidence of HIV. HIV was associated most with heterosexual promiscuity as a risk factor and presented more with extra pulmonary tuberculosis. [Int J Res Med Sci 2016; 4(8.000: 3176-3179

  19. Association between cigarette smoking and pulmonary tuberculosis

    Objectives: To determine the association between cigarette smoking and pulmonary tuberculosis. Methodology: In this retrospective study which was carried out in Razi hospital, in Ahvaz a city southwest Iran, medical charts of patients with tuberculosis between 2005 and 2007 were reviewed. Sixty one patients aged 15-96 years with documented pulmonary tuberculosis (smear positive) were selected as cases and 122 age and sex matched persons without tuberculosis(patients hospitalized in surgery and orthopedic wards) were selected randomly as controls. Data on smoking status, quantity of cigarette smoked, and duration of smoking was collected from medical charts. The data in the two groups were statistically compared with SPSS version 16. The chi square test was used to compare the frequency of cigarette smoking in two groups. Ninety-five percent confidence intervals were calculated when appropriate. Differences with a P value of <0.05 were considered significant. Results: Of total 61 case, 42 (68.9%) were smoker, while, of total 122 controls 22(18%) were smoker. The estimated odds ratio (OR) of the relation between smoking and tuberculosis was 10.1 [(95% confidence interval (CI) 4.3 to 23.5), P<0.001]. The mean of pocket - year of smoked cigarette (20/pocket) in cases and controls were 15.9 +- 13.7 and 13.5 +- 9.1, respectively (P=0.5). Conclusion: This study showed that pulmonary tuberculosis is associated to cigarette smoking. The association is not dose-dependent. Smoking may be a risk factor for TB acquisition. (author)

    The association between pulmonary tuberculosis (PTB) and diabetes mellitus (DM) has been previously attracted much attention. Diabetes alters immunity to tuberculosis, leading to more frequent treatment failure in TB patients with DM. Moreover, TB and DM often coincide with micronutrients...... deficiencies, such as retinol and vitamin D, which are especially important to immunity of the body and may influence pancreas β-cell function. However, the effects of retinol and vitamin D supplementation in active TB patients with diabetes on treatment outcomes, immune and nutrition state are still uncertain....... We are conducting a randomized controlled trial of vitamin A and/or D in active PTB patients with DM in a network of 4 TB treatment clinics to determine whether the supplementation could improve the outcome in the patients....

    2011-11-01

    Full Text Available Abstract Background The diagnosis of pulmonary tuberculosis in patients with Human Immunodeficiency Virus (HIV is complicated by the increased presence of sputum smear negative tuberculosis. Diagnosis of smear negative pulmonary tuberculosis is made by an algorithm recommended by the National Tuberculosis and Leprosy Programme that uses symptoms, signs and laboratory results. The objective of this study is to determine the sensitivity and specificity of the tuberculosis treatment algorithm used for the diagnosis of sputum smear negative pulmonary tuberculosis. Methods A cross-section study with prospective enrollment of patients was conducted in Dar-es-Salaam Tanzania. For patients with sputum smear negative, sputum was sent for culture. All consenting recruited patients were counseled and tested for HIV. Patients were evaluated using the National Tuberculosis and Leprosy Programme guidelines and those fulfilling the criteria of having active pulmonary tuberculosis were started on anti tuberculosis therapy. Remaining patients were provided appropriate therapy. A chest X-ray, mantoux test, and Full Blood Picture were done for each patient. The sensitivity and specificity of the recommended algorithm was calculated. Predictors of sputum culture positive were determined using multivariate analysis. Results During the study, 467 subjects were enrolled. Of those, 318 (68.1% were HIV positive, 127 (27.2% had sputum culture positive for Mycobacteria Tuberculosis, of whom 66 (51.9% were correctly treated with anti-Tuberculosis drugs and 61 (48.1% were missed and did not get anti-Tuberculosis drugs. Of the 286 subjects with sputum culture negative, 107 (37.4% were incorrectly treated with anti-Tuberculosis drugs. The diagnostic algorithm for smear negative pulmonary tuberculosis had a sensitivity and specificity of 38.1% and 74.5% respectively. The presence of a dry cough, a high respiratory rate, a low eosinophil count, a mixed type of anaemia and

    @@ There are a wide range of computed tomography (CT) findings in patients with pulmonary tuberculosis, including diffuse or localized nodules,reticular opacities, ground glass attenuation, air trapping, consolidation, cavitation, fibrosis, lymph nodes enlargement, and septal thickening.1-3However, CT findings of pulmonary tuberculosis that appeared as multiple cystic lesions were very rare.3,4Herein, the CT findings appeared as multiple cystic lesions in a patient with pulmonary tuberculosis are reported.

  4. Utility of CT in the evaluation of pulmonary tuberculosis in patients without Aids

    Objective. To assess the utility of CT in the evaluation of pulmonary tuberculosis in patients without AIDS. Patients and methods. Thin-section CT scans for suspicion of pulmonary tuberculosis were obtained from 226 patients. A total of 38 patients were excluded; the reasons were unavailability of final results (n=18), patient unavailability for follow-up (n=13), and coexistence of tuberculosis and aspergilloma (n=7). The results from 188 patients were used for this study. After assessing the patterns of parenchymal lesion, involved segments, and presence of cavity, bronchiectases, and bronchogenic spread of the lesion with CT, tentative diagnosis and disease activity were recorded. Results. With CT, 133 of 146 patients (91%) with tuberculosis were correctly diagnosed as having pulmonary tuberculosis whereas 32 of 42 patients (76%) without tuberculosis were correctly excluded. CT diagnosis of lung cancer (n=8), bacterial pneumonia (n=2), pulmonary metastasis (n=1), chronic hypersensitivity pneumonia (n=1) and diffuse pan-bronchiolitis (n=1) turned out to be tuberculosis. Conversely CT diagnoses of tuberculosis appeared pathologically as lung cancer (n=5), bacterial pneumonia 71/89, 80%) and inactive state (51/57, 89%) of disease respectively could be correctly differentiated by CT. Conclusion. CT can be helpful in the diagnosis of pulmonary tuberculosis in most cases. On the basis of CT findings, distinction of active from inactive disease can be made in most cases. (authors)

  5. Intestinal permeability and malabsorption of rifampin and isoniazid in active pulmonary tuberculosis

    Valéria G. F. Pinheiro

    2006-12-01

    Full Text Available Low antimycobacterial drug concentrations have been observed in tuberculosis (TB patients under treatment. The lactulose/mannitol urinary excretion test (L/M, normally used to measure intestinal permeability, may be useful to assess drug absorption. The objective of this research was to study intestinal absorptive function and bioavailability of rifampin and isoniazid in TB patients. A cross sectional study was done with 41 patients and 28 healthy controls, using the L/M test. The bioavailabilities of rifampin (R and isoniazid (H were evaluated in 18 patients receiving full doses. Urinary excretion of mannitol and lactulose, measured by HPLC, was significantly lower in TB patients. The serum concentrations of the drugs were below the expected range for R (8-24 mcg/mL or H (3-6 mcg/mL in 16/18 patients. Analyzing the drugs individually, 12/18 patients had low serum concentrations of R, 13/18 for H and 8/18 for both drugs. We suggest that there is a decrease in the functional absorptive area of the intestine in TB patients, which would explain the reduced serum concentrations of antituberculosis drugs. There is a need for new approaches to improve drug bioavailability in TB patients.

  6. Differential diagnosis between pulmonary tuberculosis and lung abscess by contrast enhanced CT

    The contrast enhanced CT findings in 14 patients with active tuberculosis and 26 patients with lung abscess were retrospectively analyzed. Reflecting the difference of pathogenesis between tuberculosis and abscess, the findings are widely different. The findings suggesting pulmonary tuberculosis rather than lung abscess were as follows; multiple and irregular necrotic areas, positive CT angiogram sign, no marginal enhancement surrounding necrosis. Contrast enhanced CT may help to distinguish pulmonary tuberculosis from lung abscess, especially in cases of caseous pneumonia showing broad consolidations or mass-like shadows. (author)

    Tl-201 lung uptake in 74 patients (85 lesions) and pulmonary perfusion in 105 patients were studied to evaluate clinical usefulness of Tl-201 lung uptake and perfusion lung scintigraphy in pulmonary tuberculosis, using a scintillation camera with a mini-computer system. As indices of Tl-201 lung uptake, lung (lesion) to upper mediastinum uptake ratio (L/M) and visual grading were used. L/M in pulmonary tuberculosis was 1.96{+-}0.66, which was significantly larger than 1.04{+-}0.24 in healthy controls and lower than that in heart diseases with left heart failure and idiopathic interstitial pneumonia, and showed no significant differences with that in acute pneumonia, pyothorax, primary lung cancer and malignant mediastinal tumor. L/M in pulmonary tuberculosis did not correlate with CRP, erythrocyte sedimentation rate, Gaffky number of sputum and body temperature. It correlated with the type of pulmonary tuberculosis according to the Gakken Classification reflecting the disease activity. It was larger in the exudative type, caseo-infiltrative one, disseminated one, one with cavity in infiltrative lesion than the fibro-caseous one. On perfusion lung scintigram, impairment of pulmonary perfusion larger than area of the entire unilateral lung was observed in 68 cases (64.8%). Area of hypoperfused lung field, which correlated with % vital capacity (r=0.60, p=0.0002) and PaO{sub 2} (r=0.39,p=0.0024), was significantly larger in patients with silicosis and those with bilateral pleural involvements such as pleural callosity than in those with type III according to the Gakkai Classification. Most of the patients showed decreased pulmonary perfusion and Tl-201 accumulation of which grade reflects the disease activity in active tuberculous lesion. Patients with miliary tuberculosis and those with silicotuberculosis showed diffuse Tl-201 accumulation in the both lungs. Tl-201 lung scintigraphy seems to be useful for visualizing active tuberculous lesions, particularly the ones

  10. Drug resistance patterns in pulmonary tuberculosis

    Objective: To determine the resistance patterns of mycobacterium tuberculosis (MTB) isolates among category I and II patients of pulmonary tuberculosis. Methods: This cross sectional study was conducted at the Department of Medicine, Liaquat University of Medical and Health Sciences Jamshoro, from November 2008 to September 2009. Patients were divided into category I and II. The sputa were collected, stained with Ziehl-Nielsen (Z-N) staining and ultimately inoculated on Lowenstein-Jensen (L-J) media for six weeks. Out of 890 pulmonary tuberculosis (PTB) patients, the growth was obtained in 285 cases. The Drug sensitivity testing (DST) for Isoniazid (INH), Rifampicin (RIF), Ethambutol (EMB) Pyrazinamide (PZA) and Streptomycin (SM) were performed. The data was analyzed on SPSS 10.0. A p-value of <0.05 was taken as significant. Result: Out of 285 cases, 176 (61.75%) were male and 109 (38.24%) female. The mean age was 37 +- 19.90 years. The DST showed drug sensitive and drug resistant isolates in 80 (28.05%) and 205 (71.92%) cases respectively (p=0.001). The drug resistant tuberculosis (DR-TB) rates for individual drugs; INH, RIF, EMB, PZA and SM were 51,22%, 15.4%, 13.33%, 9%12, and 3.85% respectively (p=0.03). The MDR-TB isolates were detected in 120 (42.10%) cases, including 5 (5.88%) in category I and 115 (57.50%) in category II patients (p=0.0001). Conclusion: Drug resistant and multidrug resistant tuberculosis was observed mainly in category II patients. However, primary MDR was also observed in category I patients and reflects dissemination of MDR cases within the community. (author)

  11. High resolution chest CT in patients with pulmonary tuberculosis: Characteristic findings before and after antituberculous therapy

    Objective: The purpose of this study was (a) to describe HRCT findings for pulmonary tuberculosis before and after treatment, and (b) to evaluate the possible use of HRCT to assess disease activity. Patients and methods: We prospectively studied 52 patients with newly diagnosed pulmonary tuberculosis that was proven bacteriologically. HRCT scans were performed before and after treatment. Results: Micronodules, nodules, tree-in-bud appearance, consolidation, and cavities were the most common HRCT findings seen in active pulmonary tuberculosis. The disappearance of tree-in-bud appearance, pleural effusion and the presence of fibrotic change appear to be indications of the effectiveness of treatment. HRCT can differentiate old fibrotic lesions from newly active tuberculous lesions. Conclusions: HRCT may be helpful in the diagnosis of pulmonary tuberculosis and may be useful in the assessment of the efficacy of anti-tuberculous treatment

    To evaluate the CT features of pulmonary tuberculosis in diabetic or immunocompromised patients, we reviewed CT of the chest in 42 adult patients with active pulmonary tuberculosis. Forty-two had some underlying diseases or immunocompromised conditions (31 diabetes mellitus, 6 malignancies, 2 long-term steroid therapy, 2 pneumoconiosis, and one anorexia nervosa). In diabetic or immunocompromised patients, a high incidence of non-segmental distribution (27%) and multiple small cavities in a cavitary lesion (45%) was observed. Unusual localization of the lesions such as lower lung field disease was observed in 18% of cases (the incidence of unusual localization in patients with no underlying disease was equal to diabetic or immunocompromised patients).

In these cases the radiological features, though suggestive of diffuse pulmonary oedema, were more prom...

  19. Pulmonary drug delivery systems for tuberculosis treatment.

    Pham, Dinh-Duy; Fattal, Elias; Tsapis, Nicolas

    2015-01-30

    Tuberculosis (TB) remains a major global health problem as it is the second leading cause of death from an infectious disease worldwide, after the human immunodeficiency virus (HIV). Conventional treatments fail either because of poor patient compliance to the drug regimen or due to the emergence of multidrug-resistant tuberculosis. The aim of this review is to give an update on the information available on tuberculosis, its pathogenesis and current antitubercular chemotherapies. Direct lung delivery of anti-TB drugs using pulmonary delivery systems is then reviewed since it appears as an interesting strategy to improve first and second line drugs. A particular focus is place on research performed on inhalable dry powder formulations of antitubercular drugs to target alveolar macrophages where the bacteria develop. Numerous studies show that anti-TB drugs can be incorporated into liposomes, microparticles or nanoparticles which can be delivered as dry powders to the deep lungs for instantaneous, targeted and/or controlled release. Treatments of infected animals show a significant reduction of the number of viable bacteria as well as a decrease in tissue damage. These new formulations appear as interesting alternatives to deliver directly drugs to the lungs and favor efficient TB treatment. PMID:25499020

  20. Primary mediastino pulmonary tuberculosis in infancy

    Primary mediastino pulmonary tuberculosis in infancy is increasing in France. Bacteriological diagnosis is difficult. The aim of the study is to assess the value of chest radiograph and CTscan for diagnosis of tuberculosis. We studied 15 infants, 3 month old to 18 month old, between November 1990 and June 1992. On plain film, lymphadenopathies were present in 13 cases and parenchymal disease in 10 cases, parenchymal nodular densities in 6 cases and pleural effusion in one case, displacement of the trachea in 6 cases. We found CTscan to be useful in delineating the lymphadenopathies and parenchymal changes. In 2 cases lymphadenopathies and in 2 cases alveolar condensation were discovered on CT scan as plain film was normal. In all cases lymphadenopathies were present in CTscan, often in right side and in al cases, lymphadenopathies were hypodense with peripheral enhancement. In conclusion, the association of right paratracheal nodes with displacement of trachea and alveolar consolidation is common in tuberculosis in infants. These findings when seen on chest radiographs must lead to perform a CTscan and suggest the diagnosis. (Authors). 19 refs., 5 figs., 4 tabs

    Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/VC%, PEF, MEF25, MEF50, MEF75, TLC, TGV, pulmonary residual volume (PRV), Raw, Rin, Rcx, DLCO-SB, DLCO-SS/VA, PaO2, and PaCO2 were determined in 40 patients with focal pulmonary tuberculosis. Changes were found in lung volumes and capacities in 75%, impaired bronchial patency and pulmonary gas exchange dysfunction were in 57.5 and 25%, respectively. The lung volume and capacity changes appeared mainly as increased TGV and PRV; impaired bronchial patency presented as decreased MEF50, MEF75, and FEV1/VC%; pulmonary gas exchange dysfunction manifested itself as reduced DLCO-SB, PaO2, and PaCO2. The magnitude of the observed functional changes was generally slight. TGV and PRL increased up to 148-187 and 142-223% of the normal values, respectively; MEF50, MEF75, FEV1/VC%, and DLCO decreased to 59-24, 58-26, 78-57, and 78-67% of the normal values and PaO2 and PaCO2 did to 79-69 and 34-30 cm Hg.

    2016-01-01

    Objective:To explore the effect of T cell subset and inflammatory cytokine levels on the prognosis in patients with pulmonary tuberculosis.Methods:A total of 72 patients confirmed with pulmonary tuberculosis who were admitted in our hospital from February, 2013 to February, 2015 were included in the study and served as the experiment group, among which 58 cases had active tuberculosis, and 14 cases had static tuberculosis; while 50 healthy individuals who came for physical examinations were served as the control group. The sputum bacteria before treatment and 6 months after treatment in the two groups were detected. The sputum negative conversion rate was recorded. The absorption of pulmonary lesions and the closure of tuberculosis cavity were examined. The immune cell function of T cell subset was detected again.Results: The peripheral blood CD3, CD4, CD8, and CD4/CD8 levels in the experiment group were significantly lower than those in the control group, especially for the active tuberculosis patients (P<0.01). The peripheral blood CD4/CD8 levels in the static tuberculosis patients was lower than that in the control group, but was significantly higher than that in active tuberculosis patients (P<0.01). The serum IL-1, IL-6, and TNF-α levels in the experiment group were significantly higher than those in the control group, especially for the active tuberculosis patients (P<0.01).Conclusions:The cell subsets and inflammatory cytokines play an important role in patients with pulmonary tuberculosis, whose dynamic change can effectively display the immune function and severity degree, which is of great value in estimating the condition and assessing the prognosis; therefore, it deserves to be further explored in the clinic.

  9. Dynamic image characteristics of pulmonary tuberculosis with diabetes mellitus

    Objective: To analyze image characteristics of pulmonary tuberculosis associated with diabetes mellitus and observe the changes of pulmonary tuberculotic lesions influenced by the state of hyperglycosemia. Methods: Examinations of chest plain film and tomography were taken in 68 patients with pulmonary tuberculosis and diabetes, and additional CT scans were done in 38 patients among them. Radiological examinations of lung and blood sugar test were taken at the interval of 2, 3, and 4-6 months in all 68 patients under the treatment of regular blood sugar control and antituberculosis, which compared with 30 patients with pulmonary tuberculosis only. Results: The images of X-ray and CT showed major lesions of massive patchy shadow in 55 patients (80.9%), or multiple small patchy shadow in 13(19.1%) and cavity 61(89.7%). After 2 month's treatment, enlargement of patchy shadow and cavity were found in 9(23.7%)and 10(28.6%)cases, respectively with overall deterioration rates of 65.8% in group of 38 patients with level of blood sugar over 7.0 mmol/L, which was significantly higher than that of the control group 7.0 mmol/L(x2=16.4, P2 = 0.81, P>0.5) with the well controlled blood sugar after treatment of 3 months or more. The follow-up images showed similar results between the groups of pulmonary tuberculosis only and the group of pulmonary tuberculosis with high level of blood sugar, in which the overall deterioration rates was significant less than the group of pulmonary tuberculosis with level of blood sugar more than 8.0 mmol/L(x2 =5.46, P<0.025). Conclusion: There are imaging characteristics in patient with pulmonary tuberculosis and diabetes mellitus. The state of hyperglycosemia is a vital factor, which influences the radiological changes of pulmonary tuberculosis

  12. Pulmonary tuberculosis - current radiological diagnosis of the ancient disease

    Incidence. Decreasing numbers of tuberculosis cases in the western countries have led to diminished attention towards this disease. But worldwide, tuberculosis still is the leading cause of mortality due to any one single infectious agent. In the industrialized countries, immigration, growth of low-income groups and increasing numbers of immunocompromised patients, mainly due to the HIV epidemic, supply a reservoir for tuberculosis. Diagnosis. Because of the option of a specific therapy, early diagnosis of tuberculosis is crucial for the course of the disease. In cases of multidrug resistant strains, further spread has to be prevented. Radiology with chest films and computed tomography has a central role in diagnosing tuberculosis. Findings. However, as the disease produces a broad spectrum of radiographic findings, there are often difficulties in determining the underlying diagnosis. Additionally, there have been reports of a typical presentations of tuberculosis in immunocompromised as well as immunocompetent patients. This article reviews the current state of radiological diagnosis of pulmonary tuberculosis. (orig.)

  14. Hypertrophic osteoarthropathy in association with pulmonary tuberculosis: a case report

    In this article the authors report a case of a patient with hypertrophic osteoarthropathy associated with pulmonary tuberculosis. This disorder is a rare complication of tuberculosis and may be associated with severe and fulminant disease. The imaging methods used in the diagnosis of this disease included lower limbs radiographs that showed bilateral periosteal reaction, and chest radiographs and computed tomography that revealed a mass in the upper lobe of the right lung. Although a fine needle aspiration was suggestive of tuberculosis, the definitive diagnosis was made after thoracotomy and histopathological examination of the mass. The patient presented symptomatic and radiological improvement after treatment of tuberculosis. (author)

  17. Computed tomography features of lung parenchymal changes in pulmonary tuberculosis

    Twenty-five patients with active pulmonary tuberculosis were prospectively studied with computed tomography (CT). Three major parenchymal patterns were noted. The nodular opacities pattern was seen in all cases. Confluent consolidation was seen in 37% of patients and consolidation with associated loss of volume (CWALV) was seen in 69% of patients. High-resolution CT (HRCT) features of bronchogenic spread included (i) a centrilobular nodule or a branching linear structure (92.3%); (ii) bronchial wall thickening (61.5%); (iii) a 'tree in bud' appearance (92.3%); and (iv) poorly marginated 5-8 mm nodules (61.5%). Most of the patterns showed satellite lesions in the form of small nodules or peripheral areas of increased attenuation. Cavitation was most common in CWALV lesions. Bronchiectasis was a common accompaniment (81.3%), and its occurrence paralleled the distribution of parenchymal lesions. Associated pleural thickening was noted in half the cases. To conclude, distinctive parenchymal changes were noted with CT in cases of pulmonary tuberculosis, which may suggest the diagnosis in the appropriate clinical setting. (authors)

    Full Text Available We aimed to characterize metabolites during tuberculosis (TB disease and identify new pathophysiologic pathways involved in infection as well as biomarkers of TB onset, progression and resolution. Such data may inform development of new anti-tuberculosis drugs. Plasma samples from adults with newly diagnosed pulmonary TB disease and their matched, asymptomatic, sputum culture-negative household contacts were analyzed using liquid chromatography high-resolution mass spectrometry (LC-MS to identify metabolites. Statistical and bioinformatics methods were used to select accurate mass/charge (m/z ions that were significantly different between the two groups at a false discovery rate (FDR of q<0.05. Two-way hierarchical cluster analysis (HCA was used to identify clusters of ions contributing to separation of cases and controls, and metabolomics databases were used to match these ions to known metabolites. Identity of specific D-series resolvins, glutamate and Mycobacterium tuberculosis (Mtb-derived trehalose-6-mycolate was confirmed using LC-MS/MS analysis. Over 23,000 metabolites were detected in untargeted metabolomic analysis and 61 metabolites were significantly different between the two groups. HCA revealed 8 metabolite clusters containing metabolites largely upregulated in patients with TB disease, including anti-TB drugs, glutamate, choline derivatives, Mycobacterium tuberculosis-derived cell wall glycolipids (trehalose-6-mycolate and phosphatidylinositol and pro-resolving lipid mediators of inflammation, known to stimulate resolution, efferocytosis and microbial killing. The resolvins were confirmed to be RvD1, aspirin-triggered RvD1, and RvD2. This study shows that high-resolution metabolomic analysis can differentiate patients with active TB disease from their asymptomatic household contacts. Specific metabolites upregulated in the plasma of patients with active TB disease, including Mtb-derived glycolipids and resolvins, have potential as

    Gomes, Manuel Mendes; Alves, Márcia; Correia, José Bernardes; Santos, Lèlita

    2013-01-01

    Empyema necessitans is a rare clinical finding nowadays. We report the case of a patient admitted in our ward for investigation of an unknown onset anterior chest wall mass, with no accompanying signs or symptoms. It is noteworthy that the patient had had pulmonary tuberculosis submitted to thoracoplasty more than 60 years before. Thoracic MRI showed a large heterogeneous mass, with a thick wall and internal septations located at the right anterior chest wall, as well as a heterogeneous content inside the right pleural cavity, with direct communication between both. An aspirative puncture of both masses was performed, with positive cultures for Mycobacterium tuberculosis, thus leading to the diagnosis of pleural tuberculosis with anterior chest wall empyema necessitans. A drain was inserted and antibiotics started. This case draws our attention to a very rare complication of pulmonary tuberculosis and its surgical treatment, though it aroused many decades after primary infection. PMID:24326441

  3. A high-resolution computed tomography-based scoring system to differentiate the most infectious active pulmonary tuberculosis from community-acquired pneumonia in elderly and non-elderly patients

    The objective of this study was to use high-resolution computed tomography (HRCT) imaging to predict the presence of smear-positive active pulmonary tuberculosis (PTB) in elderly (at least 65 years of age) and non-elderly patients (18-65 years of age). Patients with active pulmonary infections seen from November 2010 through December 2011 received HRCT chest imaging, sputum smears for acid-fast bacilli and sputum cultures for Mycobacterium tuberculosis. Smear-positive PTB was defined as at least one positive sputum smear and a positive culture for M. tuberculosis. Multivariate logistic regression analyses were performed to determine the HRCT predictors of smear-positive active PTB, and a prediction score was developed on the basis of receiver operating characteristic curve analysis. Of 1,255 patients included, 139 were diagnosed with smear-positive active PTB. According to ROC curve analysis, the sensitivity, specificity, positive predictive value, negative predictive value, false positive rates and false negative rates were 98.6 %, 95.8 %, 78.5 %, 99.8 %, 4.2 % and 1.4 %, respectively, for diagnosing smear-positive active PTB in elderly patients, and 100.0 %, 96.9 %, 76.5 %, 100.0 %, 3.1 % and 0.0 %, respectively, for non-elderly patients. HRCT can assist in the early diagnosis of the most infectious active PTB, thereby preventing transmission and minimizing unnecessary immediate respiratory isolation. (orig.)

    2014-08-01

    Full Text Available We present the design and results of empirical research, facing the actual problem of integration of theoretical and methodological knowledge of different areas of psychology to solve actual applied problems of modern physical medicine. For the first time, we described the use of gender-based approach to the study of psychological structures of disease internal picture in men aged 25 to 49, suffering from various forms of active pulmonary tuberculosis no more than 3 years. The hypothesis that individual gender characteristics are personality determinants of formation specific adaptation to the disease is confirmed by the results of empirical research. The main conclusions of the work: 1 individual gender appearance is an important psychological factor in the development of a healthy personality; 2 internalization of certain personal characteristics in individual gender space affects the features of the formation of certain types of patients relationship to the disease. The study conclusions highlight the need to complement the complex biopsychosocial rehabilitation programs of somatic patients by methods of psychological intervention from the standpoint of gender mainstreaming, thereby having significant practice oriented focus.

    Deĭkina, O N; Mishin, V Iu; Demikhova, O V

    2007-01-01

    The purpose of this investigation was to enhance the efficiency of differential diagnosis of pneumonia and pulmonary tuberculosis. A hundred and fifty-nine adult patients were examined. These included 78 patients with pulmonary tuberculosis and 81 with community-acquired p neumonia. The clinical features of infiltrative pulmonary tuberculosis (n = 48) and mild community-acquired pneumonia (n = 51) were compared. The course of caseous pneumonia (n = 30) was compared with that of moderate and severe community-acquired pneumonia (n = 30). Significant differences in the manifestations of the intoxication and bronchopulmonary syndrome were not found in patients with community-acquired pneumonia and infiltrative pulmonary tuberculosis. Physical studies showed that in patients with community-acquired pneumonia, moist rale (54.9%) and crepitation (11.8%) were prevalent, but in those with infiltrative tuberculosis rale was absent in 60.4% of cases and the pattern of respiration was unchanged in 79.2%. Chest X-ray studies indicated that in patients with community-acquired pneumonia, lower lobar inflammatory changes were predominant in 62.8% of cases whereas in those with infiltrative pulmonary tuberculosis the process was mainly bilateral (43.8%) with the presence of destructive changes (83.3%) and bronchogenic dissemination (66.7%). In patients with caseous pneumonia, the intoxication syndrome was more significant than in those with severe community-acquired pneumonia. Chest X-ray studies demonstrated that in patients with caseous pneumonia, specific changes were bilateral with the involvement of 2 lobes or more, with destruction and bronchogenic dissemination while in those with community-acquired pneumonia, the pulmonary processes were predominantly bilateral (76.6%) at the lower lobar site (36.7%).

    Objective To evaluate the application of whole blood interferon-γ release assay QuantiFERON-TB gold in tube (QFT-GIT) on the diagnosis of active pulmonary tuberculosis in China. Methods With the commercial whole blood interferon-γ QFT-GIT kit, interferon-γ released by specific T cells stimulated under early secreted antigenic target 6 kD protein ( ESAT-6) , culture filtrate protein 10 (CFP-10) and TB7. 7 were measured among 48 cases with active pulmonary tuberculosis and 55 BCG (bacillus calmette-guerin ) -vaccinated healthy controls, who had no tuberculosis contact history by questionnaire. Results The QFT-GIT was positive in 93. 8% patients with active pulmonary tuberculosis and 11.1% healthy controls, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of QFT-GIT were 93. 8% , 88. 9% , 88. 2% and 94. 1% , respectively. The antigen-specific IFN-γ release was significantly higher in patients with active pulmonary tuberculosis in comparison with that in the controls (P < 0.0001). Furthermore, after anti-tuberculosis treatment, the antigen-specific IFN-γ decreased significantly (P < 0.05). Conclusions QFT-GIT is a sensitive and specific assay for detecting tuberculosis, which could discriminate the active tuberculosis patients from BCG vaccinated healthy controls and could be a convenient and useful diagnostic tool for the diagnosis of tuberculosis.%目的 评价全血γ干扰素释放试验在活动性肺结核诊断中的应用价值.方法 应用一种全血γ干扰素释放检测试剂盒QuantiFERON-TB gold in tube(QFT-GIT)对48例活动性肺结核患者(活动性结核组)进行检测,同时选取55例健康者作为对照(对照组),均通过调查问卷排除结核病接触史.结果 本研究活动性结核组患者和对照组QFT-GIT阳性率分别为93.8%和11.1%,QFT-GIT诊断活动性肺结核的总体敏感性和特异性分别为93.8%和88.9%,阳性和阴性预测值分别为88.2%和94.1%.活动性

  13. Importance of polymerase chain reaction in diagnosis of pulmonary and extra-pulmonary tuberculosis

    Pakistan ranks eighth on the list of 22 high-burden tuberculosis (TB) countries in the world according to the World Health Organisation's (WHO) Global Tuberculosis Control 2009. Including other reasons the main cause is improper and late diagnosis of the disease. PCR may play an important role to control the disease with its rapid, sensitive and specific diagnosis. But in Pakistan due to lake of knowledge about this latest technique we are not using this technique appropriately. Clinicians still trust on conventional methods of TB diagnosis, which are time consuming or insensitive. The present study was arranged to highlight the importance of PCR in TB diagnosis in pulmonary and extra-pulmonary cases and its comparison with conventional methods. Methods: Samples obtained from 290 patients of suspected TB (pulmonary or extra-pulmonary) were subjected to ZN smear examination, LJ medium culture and PCR test by amplifying 541 bp fragment of Mycobacterium tuberculosis complex genome. The present prospective study is performed at Shalamar Hospital Lahore from November 2008 to November 2010. Results: A distinctly difference was observed in the test results done by PCR and other conventional techniques in pulmonary or extra-pulmonary tuberculosis samples (p<0.001). The sensitivity of different tests was 68.62% for PCR, 26.90% for LJ medium culture, and 14.14% for ZN smear examination (p<0.05). However, there was no significant difference between different tests as for as specificity was concerned. PCR test sensitivity in pulmonary and extra-pulmonary clinical samples was 78.34 and 61.76% respectively, being significantly higher (p<0.05) when compared with sensitivity of other tests. The mean detection time for M. tuberculosis was 25 days by LJ medium culture and less than 1 day by smear examination and PCR test. Conclusion: PCR test is more sensitive than ZN smear examination and LJ medium culture for the diagnosis of TB in pulmonary and extra-pulmonary clinical samples

    Tuberculosis is notorious that it affects various sites of the human body and presents in different ways. One of the uncommon or rather rare presentation of extra pulmonary tuberculosis is nasal tuberculosis. The nose apart from its physiological functions also contributes to facial aesthetics and gives a defined appearance and its deformity imparts cosmetic disfigurement and unsightly appearance. Both primary and secondary forms of nasal tuberculosis are rare but should be considered in the differential diagnosis of ulcerative or crusting lesions of the nose. Here we report such a case of nasal tuberculosis, which presented as an ulcerative and crusting lesion over the tip of the nose in a female child. The patient was given antituberculous chemotherapy after establishing the diagnosis and responded well to treatment. PMID:27195200

    Full Text Available OBJECTIVE: To determine the prevalence of nutritional deficiency among patients with pulmonary tuberculosis. METHODS: This was a cross-sectional study using data obtained from the Brazilian Case Registry Database and from the medical records of patients diagnosed with pulmonary tuberculosis (15-59 years of age residing in one of the municipalities that make up the 16th Regional Health District of the state of Bahia. We calculated the incidence, lethality, and mortality rates, as well as the prevalence of nutritional deficiency, as evaluated by body mass index. Demographic, social, clinical, and epidemiological data were collected. RESULTS: Of the 72 confirmed cases of tuberculosis, 59 (81.9% were in males, and 21 (29.2% of the patients were in the 40-49 year age bracket. The majority (85.3% described themselves as Mulatto or Black; 55.2% reported using alcohol; and approximately 90% were treated as outpatients. In the district and age bracket studied, the incidence of pulmonary tuberculosis was 30.6/100,000 population. Among the 72 patients, data regarding nutritional status was available for 34. Of those, 50% and 25%, respectively, presented nutritional deficiency at the beginning and at the end of treatment. No statistically significant differences were found between normal-weight and malnourished patients regarding the characteristics studied. CONCLUSIONS: The prevalence of nutritional deficiency was high among our sample of patients with pulmonary tuberculosis. This underscores the importance of nutritional follow-up for the assessment of tuberculosis treatment in the decision-making process regarding therapeutic interventions.

  18. Fluorescent analysis of lymphocytes at pulmonary tuberculosis patients exposed to irradiation

    On the territory of Belarus, damaging from the Chernobyl NPP accident, was scheduled negative pathological changes of a tuberculosis, which are displayed in heavier current of disease, decrease of an immunological reactivity and increase of a morbidity and mortality. For understanding and the interpretations of those changes were investigated lymphocytes of a peripheral blood of the pulmonary tuberculosis patients. 45 patients with the first time revealed widespread forms of a pulmonary tuberculosis, living on contaminated territories, with individual absorbed dozes of an external and internal irradiation 2 - 8 rem (at 9 patients - more than 8 rem), were investigated. Also 27 pulmonary tuberculosis patients and 25 healthy persons, which were not irradiated, were investigated too. The biophysical methods of research were used - proper and probe fluorescence, photosensitive death of cells. At the tuberculosis disease revealed changes in cells, indicating about increase of a metabolic processes level, decrease of an antioxidant system activity, a lipid bilayer viscosity and negative charge of cell membranes. The patients from contaminated territories had more expressed character of such changes. 8 refs., 1 tab

  1. [Commemorative lecture of receiving Imamura Memorial Prize. NK cell in pulmonary tuberculosis from basic and clinical point of view].

    Yoneda, T

    1996-11-01

    Although natural killer (NK) cells, which lyse certain tumors in vitro, have been shown to provide early defense mechanism against cancer growth and viral infection, possible role in the host defense against pulmonary tuberculosis remains undefined. A series of my studies have recently provided several evidence supporting the involvement of NK cells in the immunopathology of pulmonary tuberculosis. NK cell activity in patients with active pulmonary tuberculosis was significantly augmented compared with that in age-, sex- matched healthy controls, which suggests NK cells are activated in vivo in pulmonary tuberculosis. Lung NK cells from BCG-infected mice also are shown to be activated. Asialo GM 1 was demonstrated to be a novel surface marker of mice NK cells, which inhibited activation of NK cells by interferon. Chronic intractable tuberculosis was classified with a combination of NK cell activity and delayed-type hypersensitivity reaction to 2, 4-dinitrochrolbenzene. Subgroup defined with high NK cell activity and normal delayed-type hypersensitivity was characterized with moderate radiographical lesions and stable clinical course, suggesting the immune-spectrum classification was associated with clinical manifestations. Malnutrition has been suggested to be a risk factor associated with the development and reactivation of pulmonary tuberculosis. NK cell activity was significantly correlated with visceral proteins. IL-2 producing capability was significantly decreased in patients with serum albumin less than 3.5 g/dl. More recently, I established an in vitro system evaluating quantitative capability for intracellular killing by human monocytes, in which monocyte phagocytize Mycobacterium tuberculosis and subsequently inhibit intracellular replication of the organisms by adding some cytokines or cells. Purified NK cells by using discontinuous gradient centrifugation and magnetic separation technique were added to M. tuberculosis-infected monocytes monolayer

  2. Commercial serological antibody detection tests for the diagnosis of pulmonary tuberculosis: a systematic review.

    Karen R Steingart

    2007-06-01

    commercial tests in smear microscopy-negative patients, as well as their performance in children or persons with HIV infection. CONCLUSIONS: None of the commercial tests evaluated perform well enough to replace sputum smear microscopy. Thus, these tests have little or no role in the diagnosis of pulmonary tuberculosis. Lack of methodological rigor in these studies was identified as a concern. It will be important to review the basic science literature evaluating serological tests for the diagnosis of pulmonary tuberculosis to determine whether useful antigens have been described but their potential has not been fully exploited. Activities leading to the discovery of new antigens with immunodiagnostic potential need to be intensified.

  3. Tomographic findings of lobar consolidation in primary pulmonary tuberculosis

    Objective: To describe tomographic findings of lobar consolidation as early manifestation of primary pulmonary tuberculosis. Materials and methods: The present study was developed at Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2002 and 2006, retrospectively evaluating tomographic findings in four children aged from 3 to 14 months with lobar consolidation as an early manifestation of primary pulmonary tuberculosis. Results: The most frequently found radiological pattern was lobar consolidation with calcifications, cavitation and intermingle necrotic areas, associated with bulging fissure. Signs of bronchogenic dissemination and lymph node enlargement were observed in all of the four children. Consolidation with a pseudotumor aspect and masslike effect was observed in one case. Conclusion: The cases included in the present study have demonstrated that primary pulmonary tuberculosis manifested as lobar consolidation presents typical tomographic images such as cavitation, hypodense areas and calcifications intermingled with consolidation. The association with lymph node enlargement with central necrosis and signs of bronchogenic dissemination reinforce the diagnosis of tuberculosis. (author)

    J. Boldú

    2007-01-01

    Full Text Available El tratamiento de la tuberculosis es importante tanto para preservar la salud del paciente como para prevenir la propagación de la enfermedad entre la población. Sus bases bacteriológicas estriban en el elevado número de bacilos que existen en la mayor parte de lesiones humanas de la TB y en la capacidad de mutar que tiene el M. tuberculosis cuando alcanza un número elevado de divisiones; ello hace imprescindible la asociación de fármacos que eviten la selección de mutantes resistentes. En nuestro medio la terapia farmacológica que se ha demostrado más eficaz consiste en la asociación durante dos meses de isoniacida, rifampicina y piracinamida seguida durante cuatro meses más con los dos primeros fármacos. En general los tuberculostáticos de primera elección son bien tolerados, pero pueden producir efectos secundarios potencialmente graves que conviene conocer y saber manejar. En el presente trabajo describimos también cómo se debe actuar desde el punto de vista terapéutico ante determinadas situaciones especiales y cuando los tratamientos iniciales se han abandonado o han fracasado. En los últimos cinco años en Navarra, se ha incrementado de forma importante la presencia de inmigrantes procedentes de países en vías de desarrollo con altas tasas de tuberculosis y de resistencias primarias. Este colectivo genera con frecuencia, como consecuencia de sus particulares condiciones socioeconómicas y su idiosincrasia cultural, dificultades respecto al cumplimiento del tratamiento, así como en los seguimientos y controles. El tratamiento de la tuberculosis siempre debe ser realizado por médicos expertos en el tema.The treatment of tuberculosis is important both to preserve the health of the patient and to prevent the spread of the disease amongst the population. Its bacteriological bases are found in the high number of bacillae existing in the majority of human TB lesions and the capacity to mutate of Mycobacterium tuberculosis

    Objective:To investigate the sensitivity and specificity of the TSPOT.TB test in diagnosing the atypical pulmonary tuberculosis.Methods:A total of 100 patients with suspected pulmonary tuberculosis were diagnosed by TSPOT.TB test and TST, and the difference between the two detection methods was compared.Results:The positive detection rate in the atypical pulmonary tuberculosis was significantly higher than that in the pulmonary tuberculosis group. The sensitivity (94.21), specificity (94.50), PPV (74.20), NPV (94.17), and LR+ (6.14) in the atypical pulmonary tuberculosis group by TSPOT.TB test were significantly higher than those by TST, while LR-(0.13) was significantly lower than that by TST.Conclusions:When compared with TST, TSPOT. TB test has a higher clinical application value, possesses advantages of rapidness and sensitivity, and plays a vital role in diagnosing atypical pulmonary tuberculosis.

  6. A Dual Lung Scan for the Evaluation of Pulmonary Function in Patients with Pulmonary Tuberculosis before and after Treatment

    In 20 normal cases and 39 pulmonary tuberculosis cases, regional pulmonary arterial blood flow measurement and lung perfusion scans by 131I-Macroaggregated albumin, lung inhalation scans by colloidal 198Au and spirometries by respirometer were done at the Radiological Research Institute. The measured lung function tests were compared and the results were as the following: 1) The normal distribution of pulmonary blood flow was found to be 54.5±2.82% to the right lung and 45.5±2.39% to the left lung. The difference between the right and left pulmonary arterial blood flow was significant statistically (p131I-MAA in patients with pulmonary tuberculosis was as follows: a) In the pretreated minimal pulmonary tuberculosis, the decreased area of pulmonary arterial blood flow was corresponding to the chest roentgenogram, but the decrease of pulmonary arterial blood flow was more extensive than had been expected from the chest roentgenogram in the apparently healed minimal pulmonary tuberculosis. b) In the pretreated moderately advanced pulmonary tuberculosis, the decrease of pulmonary arterial blood flow to the diseased area was corresponding to the chest roentgenogram, but the decrease of pulmonary arterial blood flow was more extensive in the treated moderately advanced pulmonary tuberculosis as in the treated minimal pulmonary tuberculosis. c) Pulmonary arterial blood flow in the patients with far advanced pulmonary tuberculosis both before and after chemotherapy were almost similar to the chest roentgenogram. Especially the decrease of pulmonary arterial blood flow to the cavity was usually greater than had been expected from the chest roentgenogram. 3) Lung inhalation scan by colloidal 198Au in patients with pulmonary tuberculosis was as follows: a) In the minimal pulmonary tuberculosis, lung inhalation scan showed almost similar decrease of radioactivity corresponding to the chest roentgenogram. b) In the moderately advanced pulmonary tuberculosis the decrease of

    2012-08-01

    Full Text Available Background: Pulmonary tuberculosis (PTB is one of the most grave public health problem and account for four fifth of all tuberculosis cases. PTB is the key source of spread of mycobacterium. Revised National Tuberculosis Control Programme (RNTCP adopted passive surveillance strategy of the chest symptomatic for identification of cases of PTB. Therefore, it is utmost important that the basic information about PTB and services provided under the program is clear in community. Methodology: A cross sectional observational study was conducted among 176 patient taking treatment of PTB from Health Centers of Surat District. Results: More than 80 percent of the respondents were aware of symptomatology of PTB. Almost all (96.7% of patient were aware about one person to other person mode of transmission of tuberculosis. Almost half were aware about the infective organism as cause of disease and more than one third patients were aware of diagnostic investigations of PTB. However only 9% of patients were know about BCG immunization as means of prevention for tuberculosis. Most of the respondents 95% believed that tuberculosis is curable. Conclusion: The current study revealed that although awareness regarding certain basic aspect of tuberculosis was adequate; however there is a great need to improve awareness in illiterate individuals and females. Importance of BCG vaccination needs to be appreciated in community through continuation and innovations in IEC. [Natl J of Med Res 2012; 2(4.000: 452-455

    Background The correct diagnosis of sputum smear-negative pulmonary tuberculosis in AIDS patients is very important to their therapy.We aimed to assess the value of the computed tomography (CT) and clinical findings in predicting smearnegative pulmonary tuberculosis in AIDS patients.Methods A total of 121 AIDS patients suspected of smear-negative pulmonary tuberculosis by clinical and radiographic findings were recruited.Pulmonary tuberculosis was diagnosed in 57 (47.1%) patients.The CT and clinical predictors were selected to diagnose AIDS-related pulmonary tuberculosis through univariate and multivariate Logistic analysis.Results Multivariate analysis showed that five variables,including weight loss,presence of miliary nodules,necrotic lymph node,Iobular consolidation,tree-in-bud sign,were independent predictors of pulmonary tuberculosis in AIDS patients.Predicted scores based on the five variables were used to identify pulmonary tuberculosis.If the predicted score of 3 was taken as the ideal cut-off point in the diagnosis of AIDS-related smear-negative pulmonary tuberculosis,the sensitivity,specificity,positive predictive value,negative predictive value,and accuracy were 84.2%,81.2%,80.0%,85.2%,and 82.6%,respectively.Conclusion The prediction method based on five key factors of clinical and CT findings are useful in guiding the diagnosis of smear-negative pulmonary tuberculosis in AIDS patients.

  10. Pleuropulmonary Paragonimiasis mimicking Pulmonary Tuberculosis - A Report of Three Cases

    Singh T

    2005-01-01

    Full Text Available Paragonimiasis is an important cause of pulmonary disease worldwide. Infection in humans mainly occurs by ingestion of raw or undercooked freshwater crabs or crayfishes. The disease is well known in endemic regions of Asian countries, where culturally based methods of food preparation foster human transmission. Three patients with clinical and radiological features compatible with pulmonary tuberculosis had been treated for tuberculosis without remedy despite an inability to demonstrate acid fast bacilli in sputum smears. All patients had history of ingestion of raw crabs and crayfishes. The confirmed diagnosis of pleuropulmonary paragonimiasis was made based on the demonstration of Paragonimus eggs in the sputum, and high absolute eosinophilia in their peripheral blood and pleural fluid. All the patients had been treated with praziquantel successfully.

    2012-01-01

    Patients with lung cancer are often misdiagnosed as pulmonary tuberculosis leading to delay in the correct diagnosis as well as exposure to inappropriate medication. Several factors are responsible for this situation in developing countries, including lack of awareness, inadequate infrastructure and socio-economic factors. This article outlines the differences between the two diseases as well as features that would make a clinician suspect the right diagnosis early.

  13. Pulmonary impairment after tuberculosis and its contribution to TB burden

    Munguia Guadalupe

    2010-05-01

    Full Text Available Abstract Background The health impacts of pulmonary impairment after tuberculosis (TB treatment have not been included in assessments of TB burden. Therefore, previous global and national TB burden estimates do not reflect the full consequences of surviving TB. We assessed the burden of TB including pulmonary impairment after tuberculosis in Tarrant County, Texas using Disability-adjusted Life Years (DALYs. Methods TB burden was calculated for all culture-confirmed TB patients treated at Tarrant County Public Health between January 2005 and December 2006 using identical methods and life tables as the Global Burden of Disease Study. Years of life-lost were calculated as the difference between life expectancy using standardized life tables and age-at-death from TB. Years lived-with-disability were calculated from age and gender-specific TB disease incidence using published disability weights. Non-fatal health impacts of TB were divided into years lived-with-disability-acute and years lived-with-disability-chronic. Years lived-with-disability-acute was defined as TB burden resulting from illness prior to completion of treatment including the burden from treatment-related side effects. Years lived-with-disability-chronic was defined as TB burden from disability resulting from pulmonary impairment after tuberculosis. Results There were 224 TB cases in the time period, of these 177 were culture confirmed. These 177 subjects lost a total of 1189 DALYs. Of these 1189 DALYs 23% were from years of life-lost, 2% were from years lived-with-disability-acute and 75% were from years lived-with-disability-chronic. Conclusions Our findings demonstrate that the disease burden from TB is greater than previously estimated. Pulmonary impairment after tuberculosis was responsible for the majority of the burden. These data demonstrate that successful TB control efforts may reduce the health burden more than previously recognized.

  16. Tuberculosis associated pulmonary hypertension: The revelation of a clinical observation

    Parthasarathi Bhattacharyya

    2016-01-01

    Full Text Available Background: Pulmonary tuberculosis is not listed as a cause of pulmonary hypertension (PH. Scanty information is available in the literature regarding this issue. Methods: A group of patients with a history of pulmonary tuberculosis were diagnosed to have PH on the basis of a novel clinico-radio-echocardiographic criteria. Subdivided into two groups on the basis of the history of smoking, we looked for their demographic, spirometric, radiological characteristics along with the quality of life assessment. Results: A total of 40 patients (21 smokers and 19 nonsmokers were found to have PH with history of pulmonary tuberculosis. The two groups were similar radiologically including the extent of fibrosis. The nonsmoker group had lower age range (52.16 ± 14.81 vs. 63.1 ± 10.05, P = 0.01, worse chronic obstructive pulmonary disease (COPD assessment test score (16.11 ± 6.24 vs. 13.9 ± 5.6, P = 0.25 and higher pulmonary artery (PA pressure (46.39 ± 7.44 vs. 44.55 ± 8.04, P = 0.46 compared to the smokers. Overall and for the smoker group, in particular, the spirometric pictures were favoring obstruction without reversibility as in COPD (forced expiratory volume in 1 second [FEV1] % as 64.26 ± 18.38 and 58.85 ± 14.61 with % of predicted FEV1being 43.74 ± 17.26 and 42.38 ± 16.64 respectively. However, those with no history of smoking had restrictive changes as in diffuse parenchymal lung disease (DPLD in their spirometry (FEV1/forced vital capacity [FVC] of 79.33 ± 19.93 and FVC as 49.67 ± 11.54% of predicted. The smoker group had far more obvious involvement of the small airways in terms of change in FEF25-75compared to nonsmokers (FEF25-75 = 22.85 ± 19.68 vs. 63.83 ± 48.61. Conclusion: PH appears associated with the history of pulmonary tuberculosis. With or without a history of smoking, they pose two distinct phenotypes in spirometry as COPD and DPLD. The DPLD phenotype had worse quality of life.

    2012-11-01

    Full Text Available OBJECTIVE: Pleural tuberculosis is the most frequently occurring form of extra pulmonary disease in adults. In up to 40% of cases, the lung parenchyma is concomitantly involved, which can have an epidemiological impact. This study aims to evaluate the pleural and systemic inflammatory response of patients with pleural or pleuropulmonary tuberculosis. METHODS: A prospective study of 39 patients with confirmed pleural tuberculosis. After thoracentesis, a high resolution chest tomography was performed to evaluate the pulmonary involvement. Of the 39 patients, 20 exhibited only pleural effusion, and high resolution chest tomography revealed active associated-pulmonary disease in 19 patients. The total protein, lactic dehydrogenase, adenosine deaminase, vascular endothelial growth factor, interleukin-8, tumor necrosis factor-α, and transforming growth factor-β1 levels were quantified in the patient serum and pleural fluid. RESULTS: All of the effusions were exudates with high levels of adenosine deaminase. The levels of vascular endothelial growth factor and transforming growth factor-β1 were increased in the blood and pleural fluid of all of the patients with pleural tuberculosis, with no differences between the two forms of tuberculosis. The tumor necrosis factor-α levels were significantly higher in the pleural fluid of the patients with the pleuropulmonary form of tuberculosis. The interleukin-8 levels were high in the pleural fluid of all of the patients, without any differences between the forms of tuberculosis. CONCLUSION: Tumor necrosis factor-α was the single cytokine that significantly increased in the pleural fluid of the patients with pulmonary involvement. However, an overlap in the results does not permit us to suggest that cytokine is a biological marker of concomitant parenchymal involvement. Although high resolution chest tomography can be useful in identifying these patients, the investigation of fast acid bacilli and cultures

    Full Text Available Background. Dietary supplementation has been used as a mechanism to augment the immune system. Adjunctive therapy with L-arginine has the potential to improve outcomes in active tuberculosis. Methods. In a randomized clinical trial 63 participants with smear-positive pulmonary tuberculosis in Markazi Province of Iran were given arginine or placebo for 4 weeks in addition to conventional chemotherapy. The final treatment success, sputum conversion, weight gain, and clinical symptoms after one and two months were considered as primary outcomes and secondary outcomes were ESR, CRP, and Hg. Data were collected and analyzed with SPSS software (ver. 18. Results. Arginine supplementation reduced constitutional symptoms (P=0.032 in patients with smear-positive TB at the end of the first month of treatment. Arginine treated patients had significantly increased BMI at the end of the first and second months of treatment (P=0.032 and P=0.04 and a reduced CRP at the end of the first month of treatment (P=0.03 versus placebo group. Conclusion. Arginine is useful as an adjunctive therapy in patients with active tuberculosis, in which the effects are more likely mediated by the increased production of nitric oxide and improved constitutional symptoms and weight gain. This trial is registered with Clinical Trials Registry of Iran: IRCT201211179855N2.

  20. The similar hexheimer reaction during initial treatment of pulmonary tuberculosis: CT appearances

    Objective: To investigate CT features of similar Hexheimer's reaction during initial treatment of active pulmonary tuberculosis. Methods: The similar Hexheimer's reaction in 44 patients diagnosed by clinic and follow-up CT scans were retrospectively reviewed by three radiologists. Results: During initial treatment of active pulmonary tuberculosis, development of radiographic progression were observed in 57 foci, including 28 pulmonary lesions increased at the site of their original lesion or new opacities elsewhere, ipsilateral or contralateral to the original lesion or both, 10 lesions related to the pleura (pleural effusion, pleural tuberculoma), 15 lymphadenectasis, 3 thymus reactions, and 1 cardiac pericardium thickening, respectively. These reactions appeared from the 20 days to 3.5 months, then with continuation of the initial chemotherapy for 1.0-3.0 months, the radiographic response was excellent with the areas of progression and the original lesions demonstrating resolution or improvement. Conclusion: The CT appearances of similar Hexheimer's reaction during initial treatment of active tuberculosis are specific to a certainty. (authors)

    Full Text Available Abstract Background Delays seeking care worsen the burden of tuberculosis and cost of care for patients, families and the public health system. This study investigates costs of tuberculosis diagnosis incurred by patients, escorts and the public health system in 10 districts of Ethiopia. Methods New pulmonary tuberculosis patients ≥ 15 years old were interviewed regarding their health care seeking behaviour at the time of diagnosis. Using a structured questionnaire patients were interviewed about the duration of delay at alternative care providers and the public health system prior to diagnosis. Costs incurred by patients, escorts and the public health system were quantified through patient interview and review of medical records. Results Interviews were held with 537 (58% smear positive patients and 387 (42% smear negative pulmonary patients. Of these, 413 (45% were female; 451 (49% were rural residents; and the median age was 34 years. The mean (median days elapsed for consultation at alternative care providers and public health facilities prior to tuberculosis diagnosis was 5 days (0 days and 3 (3 days respectively. The total median cost incurred from first consultation to diagnosis was $27 per patient (mean = $59. The median costs per patient incurred by patient, escort and the public health system were $16 (mean = $29, $3 (mean = $23 and $3 (mean = $7 respectively. The total cost per patient diagnosed was higher for women, rural residents; those who received government food for work support, patients with smear negative pulmonary tuberculosis and patients who were not screened for TB in at least one district diagnostic centers. Conclusions The costs of tuberculosis diagnosis incurred by patients and escorts represent a significant portion of their monthly income. The costs arising from time lost in seeking care comprised a major portion of the total cost of diagnosis, and may worsen the economic position of patients and their families

  2. Peculiarities of the hormone regulation in patients with pulmonary tuberculosis living in the unfavourable radioecological conditions

    The hormone regulation indices are studies in 83 patients with the pulmonary tuberculosis of the frequent forms living on contamination territories with gamma-background more 10 Ci/sq.km, as well as 60 patients with the same diseases and 35 practically healthy people living in clear territories. It is stated that in patients who were exposed to irradiation, particularly in those with the disease unfavourable run, the thyroid functional activity as well as the insulin and sex hormones secretion and adrenal gland and pituitary body stress reaction are decreased. The prognostic value of the blood plasma thyrotropin, thyroxine and testosterone content study in patients with primarily revealed pulmonary tuberculosis is determined. No significant dependence of the studied parameters on the calculated irradiation dose was found. (author). 8 refs., 1 tab

    Extra-osseous uptake of bone-seeking radiopharmaceuticals has been reported at various sites and it is known to be induced by various causes. Diffuse pulmonary infection, such as tuberculosis, can be a cause of lung uptake of bone-scan agent. Here we report on a patient with non-tuberculosis mycobacterial infection (NTM) who demonstrated diffuse pulmonary uptake on Tc-99m MDP bone scan. After medical treatment for NTM, the patient's lung lesions improved. Estra skeletal lung Tc-99m MDP uptake on bone scan may suggest lung parenchymal damage associated with disease activity.

    2016-02-01

    Full Text Available Background: In South Africa, pulmonary tuberculosis (PTB remains a problem of epidemic proportions. Despite evidence demonstrating persistent lung impairment after PTB cure, few population-based South African studies have investigated this finding. Pulmonary rehabilitation post-cure is not routinely received.Objectives: To determine the effects of PTB on lung function in adults with current or past PTB. To determine any association between PTB and chronic obstructive pulmonary disease (COPD. Methods: This study was observational and cross-sectional in design. Participants (n = 55 were included if they were HIV positive on treatment, had current PTB and were on treatment, and/or had previous PTB and completed treatment or if they were healthy adult subjects with no history of PTB. A sample of convenience was used with participants coming from a similar socio-economic background and undergoing spirometry testing. Multiple regression analyses were conducted on each lung function variable.Results: Compared to normal percentage-predicted values, forced expiratory volume in 1 second (FEV1 , forced vital capacity (FVC and FEV1 :FVC were significantly reduced in those with current PTB by 23.39%, 15.99% and 6.4%, respectively. Both FEV1 and FVC were significantly reduced in those with past PTB by 11.76% and 10.79%, respectively. There was no association between PTB and COPD – those with previous PTB having a reduced FEV1 :FVC (4.88% less than the norm, which was just short of significance (p = 0.059.Conclusions: Lung function is reduced both during and after treatment for PTB and these deficits may persist. This has implications regarding the need for pulmonary rehabilitation even after medical cure.Keywords: Lung function, pulmonary, tuberculosis

  10. Increasing pathomorphism of pulmonary tuberculosis: an observational study of slow clinical, microbiological and imaging response of lung tuberculosis to specific treatment. Which role for linezolid?

    Roberto Manfredi

    2009-08-01

    Full Text Available During recent years, a progressive emerging of tuberculosis occurred, related to the overall increased age of general population, primary and secondary (iatrogenic immunodeficiencies, the availability of invasive procedures, surgical interventions and intensive care supports, bone marrow and solid organ transplantation, and especially the recent immigration flows of people often coming from areas endemic for tuberculosis, and living with evident social-economical disadvantages, and with a reduced access to health care facilities. Since January 2006, at our reference centre we followed 81 consecutive cases of pulmonary tuberculosis, with 65 of them which remained evaluable for the absence of extrapulmonary complications, and a continuative and effective clinical and therapeutic follow-up. The majority of episodes of evaluable pulmonary tuberculosis (49 cases out of 65: 75,4% occurred in patients who immigrated from developing countries. In two patients multiresistant (MDR Mycobacterium tuberculosis strains were found, while two more subjects (both immigrated from Eastern Europe suffered from a disease due to extremely resistant (XDR M. tuberculosis strains. Although enforcing all possible measures to increase patients' adherence to treatment (empowerment, delivery of oral drugs under direct control, use of i.v. formulation whenever possible, over 72% of evaluable patients had a very slow clinical, microbiological, and imaging ameliorement (1-6 months, with persistance of sputum and/or bronchoalveolar lavage (BAL fluid positive for M.tuberculosis microscopy and/or culture for over 1-4 months (mean 9.2±3.2 weeks, during an apparently adequate treatment. When excluding patients suffering from XDR and MDR tuberculosis, in four subjects we observed that off-label linezolid adjunct together with at least three drugs with residual activity against tuberculosis, led to a significantly more rapid clinical-radiological improvement and negative

  12. Psychiatric morbidity in patients of pulmonary tuberculosis-an observational study

    Lalit Singh

    2015-01-01

    Full Text Available Background: A lot of stigma and misconceptions about pulmonary tuberculosis still persist, in spite of the advances in treatment. Thus, a mere diagnosis of pulmonary tuberculosis can be a psychological trauma to an individual. The situation has aggravated with the association of tuberculosis with HIV infection. Aim: To study the psychiatric morbidity due to the various psychological stresses faced by a patient of pulmonary tuberculosis. Materials and Methods: The study group consisted of 100 inpatients admitted to pulmonary ward with diagnosis of pulmonary tuberculosis. The control group consisted of 100 inpatients admitted to pulmonary ward with nontuberculous pulmonary diseases. Psychiatric history and mental status were recorded on a specially designed proforma and diagnosis of any psychiatric illness, if present, arrived at as per International Classification of Diseases (ICD-10. The psychiatric tests applied were beck's depression inventory (BDI and Taylor's Manifest Anxiety Scale (TMAS. Results: Of the patients of pulmonary tuberculosis, 24% could be given a diagnostic category, as per ICD-10, as compared to only 8% of the controls (P < 0.005. On BDI, 44% of patients of pulmonary tuberculosis showed depression as compared to 27% of the controls (P < 0.02. On TMAS, 38% of patients of pulmonary tuberculosis showed anxiety as compared to 24% of controls (P < 0.05. A greater incidence of depression (on BDI and anxiety (on TMAS was seen in those with longer duration of illness (P < 0.02 and in those with greater severity of illness (P < 0.02. Conclusion: In view of the high psychiatric morbidity associated with pulmonary tuberculosis, there is enough scope for psychiatric services to be made available to these patients. In addition, personnel involved in the treatment of these patients should be trained for early detection of psychiatric symptoms.

  15. Pulmonary Impairment in Tuberculosis Survivors: The Korean National Health and Nutrition Examination Survey 2008-2012.

    Jae-Woo Jung

    Full Text Available Pulmonary tuberculosis (TB can affect lung function, but studies regarding long-term follow-up in patients with no sequelae on chest X-ray (CXR have not been performed. We evaluated lung functional impairment and persistent respiratory symptoms in those with prior pulmonary TB and those with prior pulmonary TB with no residual sequelae on CXR, and determined risk factors for airflow obstruction.We used data from adults aged ≥ 40 years from the annual Korean National Health and Nutrition Examination Surveys conducted between 2008 and 2012. P values for comparisons were adjusted for age, sex, and smoking status.In total of 14,967 adults, 822 subjects (5.5% had diagnosed and treated pulmonary TB (mean 29.0 years ago. The FVC% (84.9 vs. 92.6, FEV1% (83.4 vs. 92.4, and FEV1/FVC% (73.4 vs. 77.9 were significantly decreased in subjects with prior pulmonary TB compared to those without (p < 0.001, each. In 12,885 subjects with no sequalae on CXR, those with prior pulmonary TB (296, 2.3% had significantly lower FEV1% (90.9 vs. 93.4, p = 0.001 and FEV1/FVC% (76.6 vs. 78.4, p < 0.001 than those without. Subjects with prior pulmonary TB as well as subjects with no sequalae on CXR were more likely to experience cough and physical activity limitations due to pulmonary symptoms than those without prior pulmonary TB (p < 0.001, each. In total subjects, prior pulmonary TB (OR, 2.314; 95% CI, 1.922-2.785, along with age, male, asthma, and smoking mount was risk factor for airflow obstruction. In subjects with prior pulmonary tuberculosis, inactive TB lesion on chest x-ray (OR, 2.300; 95% CI, 1.606-3.294 were risk factors of airflow obstruction.In addition to subjects with inactive TB lesion on CXR, subjects with no sequelae on CXR can show impaired pulmonary function and respiratory symptoms. Prior TB is a risk factor for airflow obstruction and that the risk is more important when they have inactive lesions on chest X-ray. Hence, the patients with treated TB

  16. Ayurvedic management of Pulmonary Tuberculosis (PTB: A systematic review

    Janmejaya Samal

    2016-03-01

    Full Text Available Background: Tuberculosis is a global public health crisis. 25% of world's TB cases are found in India. Ayurveda, an ancient medical science may offer some solution to this problem hence a systematic review was carried out to assess the role of Ayurveda for the management of Tuberculosis. Methodology: A systematic review was carried out using published literature obtained through and ldquo;PUBMED and rdquo; till April 2015. The key words used for literature search include and ldquo;Ayurveda, role and Tuberculosis and rdquo;. Results and Discussion: It was observed that a couple of single and compound drugs have been used for the management of tuberculosis. However none of the studies could reflect the true anti-tubercular activities of any drug, both single and compound. Two of the studies revealed in vitro anti-tubercular properties of some herbs which can potentially be brought in to the realm of clinical trial to test their efficacy in human subject. Most of these Ayurvedic therapeutic preparations studied at different clinical settings primarily reflected their adjunct properties for the management of Tuberculosis. These studies revealed that Ayurvedic therapeutics were able to reduce associated symptoms and the adverse drug effects of ATDs (Antitubercular Drugs. Furthermore some of the preparations showed potential hepato-protective properties that can be simultaneously administered with ATDs. Conclusion: Distressingly research on the role of Ayurveda in the management of Tuberculosis is very scanty and mostly limited to adjunct or supportive therapy. Being a global public health crisis, it is highly recommended to carry out clinical trials on Tuberculosis patients by using Ayurvedic drugs and therapeutic regimens.

    Full Text Available Vast majority of active tuberculosis patients seeks treatment, do so promptly, still many patients spend a great deal of time and money “shopping for health” and too often they do not receive either accurate diagnosis or effective treatment, despite spending considerable resources. Objective: To find out the time taken to, for diagnosis of tuberculosis and to put patient on DOTS from the onset of symptoms and pattern of health seeking behavior of new pulmonary tuberculosis patients. A cross-sectional rapid assessment using qualitative (FGD and quantitative (Interview methods conducted at DOTS center of tertiary care hospital from rural Wardha. Participants: 53 pulmonary tuberculosis patients already on DOTS, in intensive phase. Main outcome measure: Delay in initiation of DOTS & health seeking behavior Results: Median total delay for starting DOTS was 111 days, (range: 10 to 321 days. Patient delay was more than provider delay. Patients delay was more in patients above 60 years, illiterate, per-capita income below 650 Rupees and HIV TB co-infection. Pattern of health seeking behavior was complex. Family physician was the preferred health care provider. Patient visited on an average four providers and spent around 1450 rupees (only direct cost before DOTS begin. Time taken from the onset of symptoms and start of DOT is a cause of concern for the tuberculosis control program. Early case detection is important rather than mere achieving target of 70% new case detection. Program manager needs to implement locally relevant & focused strategies for early case detection to improve the treatment success, especially in rural area of India.

  19. Drug resistance pattern in multidrug resistance pulmonary tuberculosis patients

    To evaluate the frequency of drug resistance profiles of multidrug resistant tuberculosis (MDR-TB) isolates of pulmonary tuberculosis patients, against both the first and the second line drugs. Study Design: An observational study. Place and Duration of Study: The multidrug resistant tuberculosis (MDR-TB) ward of Ojha Institute of Chest Diseases (OICD), Karachi, from 1996 to 2006. Methodology: Culture proven MDR-TB cases (resistant to both isoniazid and Rifampicin) were retrospectively reviewed. Susceptibility testing was performed at the clinical laboratory of the Aga Khan University. Sensitivity against both first and second line anti-tuberculosis drugs was done. Susceptibility testing was performed using Agar proportion method on enriched middle brook 7H10 medium (BBL) for Rifampicin, Isoniazid, Streptomycin, Ethambutol, Ethionamide, Capreomycin and Ciprofloxacin. Pyrazinamide sensitivity was carried out using the BACTEC 7H12 medium. During the study period MTB H37Rv was used as control. Results: Out of total 577 patients, all were resistant to both Rifampicin and Isoniazid (INH). 56.5% isolates were resistant to all five first line drugs. Resistances against other first line drugs was 76.60% for Pyrazinamide, 73% for Ethambutol and 68.11% for Streptomycin. Five hundred and ten (88%) cases were MDR plus resistant to one more first line drug. Forty (07%) isolates were MDR plus Quinolone-resistant. They were sensitive to Capreomycin but sensitivity against Amikacin and Kanamycin were not tested. Conclusion: There were high resistance rates in MDR-TB to remaining first line and second line drugs. Continuous monitoring of drug resistance pattern especially of MDR isolates and treatment in specialized centers is a crucial need for future TB control in Pakistan. (author)

  20. Transcatheter arterial embolization for control of hemoptysis in pulmonary tuberculosis: analysis of prognostic factors

    To evaluate the effectiveness of transcatheter arterial embolization(TAE) and the relationship between therapeutic effect and prognostic factors after this procedure. Fifty-five patients with hemoptysis caused by pulmonary tuberculosis (TB) underwent TAE. We reviewed medical records of the history and activity of pulmonary TB, and the extent of treatment, and assessed plain chest PA for the extent of lesions;we also evaluated the angiographic findings of embolized arteries, and embolic agents. The initial success rate, as shown by immediate response, and recurrence during follow-up, were then observed. Using the Chi-square test, differences in these findings were analysed. Immediate control of hemoptysis was achieved in 46 of 55 patients(84%);24 of 46(52.2%), experienced recurrence. Initial failure and partial response rates were higher in patients with active pulmonary TB(p<0.05) than in those in whom the condition was inactive. The recurrence rate was higher among those who had pulmonary TB for between one and ten years (p<0.05). There was, however, no significant correlation between therapeutic effect and the extent of anti-TB treatment, the extent of lesions seen on plain chest PA, angiographic findings, embolized arteries, and embolic agents. The initial success rate of TAE was 84% and the recurrence rate was as high as 52.2%. Both activity and duration of pulmonary TB were prognostic factors in immediate response and recurrence.=20

  1. Surgical Treatment of Complications of Pulmonary Tuberculosis, including Drug-Resistant Tuberculosis

    Rajhmun Madansein

    2015-03-01

    Full Text Available Surgery for drug-resistant tuberculosis has been shown to be safe and effective, with similar level of mortalities associated with surgical intervention observed with that for lung cancer. While surgery has been an option to treat TB in the pre-antibiotic era, it is now increasingly used to treat complications of pulmonary TB, particularly in patients with drug-resistant TB who do not respond to medical treatment. The two most frequent indications for lung resection in drug- resistant TB, are i failed medical treatment with persistent sputum positivity or ii patients who have had medical treatment and are sputum negative, but with persistent localized cavitary disease or bronchiectasis. Massive hemoptysis is a potentially life-threatening complication of TB. Lung resection is potentially curative in patients with massive hemoptysis and cavitary or bronchiectatic disease. Bronchial artery embolization in these patients has a high success rate but bears also the risk of recurrence. Lung resection can be safely undertaken in selected patients with HIV co-infection and pulmonary complications of TB. Ambulatory drainage is a novel, safe, affordable and effective method of draining a chronic TB associated empyema thoracis. We review here the current surgical treatment of the complications of pulmonary TB and discuss the experience from the Durban Cardiothoracic Surgery Unit for the surgical treatment of patients with complicated pulmonary TB.

    Tuberculosis is a contagious disease induced by Mycobacterium species, acid-fast bacilli. These are mostly human type--Mycobacterium tuberculosis, less often cattle type--mycobacterium bovis or other: mycobacterium avium, kansasii, marinom, scrofulaceum, heamophilium, gordonae. The infection can affect all organs, but pulmonary tuberculosis is the most common form. The importance of tuberculosis is definitely rising in the context of massive population migrations in regions affected by its higher incidence, increased HIV infections and AIDS development. Cutaneous tuberculosis is a particular tuberculosis form with differentiated clinical picture. Non-typicalness of skin changes and oligobacilleous course of extrapulmonary tuberculosis forms are repeatedly causing difficulties in adequate diagnosis and early treatment. In differential diagnostics of cutaneous tuberculosis one must take leishmaniasis, actinomycosis, leprosy, syphilis and deep mycosis (among others) into consideration. The study is presenting a case of lupus vulgaris as a complication of past pulmonary tuberculosis. In bacteriological diagnostics of skin changes bioptates, no tuberculosis mycobacteria were found. The disease was diagnosed based on specific granulation presence in histopathology test, tuberculin hypersensivity, bacilli DNA presence in polymerase chain reaction (PCR) test and skin changes regression after anti-mycobacterium treatment. According to authors of the study, the described case confirms the usefulness of PCR nucleonic acids amplification test in cutaneous tuberculosis diagnosis. PMID:19928663

    BACKGROUND: Prisons offer a fertile setting for the transmission of tuberculosis due to the presence of many classic risk factors for both infection and disease: overcrowding, poor ventilation, and little sunlight. Prisoners are often malnourished and have poor hygiene and are more likely to have a background of alcohol and drug abuse. OBJECTIVES: To determine the prevalence of prisoners with respiratory symptoms and pulmonary tuberculosis (PTB) through active case finding in a prisoner popul...

    2002-01-01

    A case of Pulmonary Alveolar Proteinosis (PAP), in association with tuberculosis, is described in a 35-year-old diabetic patient. Lung biopsy showed an intra-alveolar accumulation of PAS-positive material, and multifocal granulomas compatible with tuberculosis. The bronchoalveolar culture was positive for Mycobacterium tuberculosis. PAP results from an imbalance of the mechanisms that regulate the homeostasis of the surfactant, where specific proteins are involved, especially SP-A and SP-D, t...

  6. [The interpretation of pulmonary tuberculosis in the 18th century].

    Bernier, Jacques

    2005-01-01

    Pulmonary tuberculosis took on alarming proportions in the 18th-century Europe. This study examines the ways learned medical practitioners presented the causes of the malady in Great Britain and France, by analyzing 12 medical treatises. Four etiological models appears to have dominated medical thinking in this context: theories that emphasize contagion; those which attribute the cause to physiological disorders; those which find the origin in hereditary predispositions; and those theories which observe a link with behaviour and lifestyles. The study also shows how one of these theories - the hereditary theory - eventually triumphed over the others and became the dominant for the better part of the 19th century, and will be examined within the context of the growth of liberal and individualist ideology.

    Full Text Available Context: Mycobacterium tuberculosis (MTB infection is rarely seen in cystic fibrosis (CF patients. Case Report: We report a 24-year-old CF patient with fever, cough, hemoptysis, and weight loss of 1week duration prior to admission. Past sputum cultures grew methicillin-resistant Staphylococcus aureus and Pseudomonas aeruginosa. The patient was treated with broad spectrum antibiotics based on previous culture data, but failed to improve. Chest radiograph and computed tomography (CT chest revealed chronic collapse of the anterior subsegment of right upper lobe and multiple bilateral cavitary lesions which were worse compared to prior films. MTB was suspected and was confirmed by positive acid-fast bacilli (AFB smears and cultures. After receiving first-line antituberculous drugs, the patient′s condition markedly improved. Conclusion: MTB is an infrequent finding, but considered a potential pathogen in CF patients, and may lead to serious pulmonary complications if there is a delay in diagnosis and treatment.

    Full Text Available Wegener′s granulomatosis (WG is an uncommon autoimmune disease with multi-system involvement that manifests as vasculitis, granulomatosis, and necrosis. While its standard form involves the upper and lower respiratory tracts and kidneys, it may essentially involve any organ. We present a case in a young female patient presenting with symptoms of cough with expectoration, fever, dyspnea and chest discomfort, having cavitating lesion in right upper lobe and nodule in left upper lobe with bilateral paranasal sinus involvement on computed tomography. Allergic rhino-sinusitis with pulmonary tuberculosis was suspected, and patient was investigated further. Upon further investigation, renal involvement was detected, and serology revealed cytoplasmic antineutrophil cytoplasmic antibody. WG was suspected and was proven by histopathology of nasal tissue which revealed necrotizing granulomas.

  9. Primary pulmonary tuberculosis in infancy: A resurgent disease in the urban United States

    Primary pulmonary tuberculosis in infancy still exists in the urban United States, reflecting new immigrations from less developed areas. The clinical diagnosis may be difficult and routine chest radiographs may be confusing. We found magnification high KV filtered radiography to be very useful in delineating the primary complex and its effect on the tracheobronchial tree. Twelve infants and small children with primary pulmonary tuberculosis were seen in the years 1978-1984. (orig.)

    2014-04-01

    Full Text Available Aim: To determine the relation between radiographic involvement and tuberculin skin test (TST and Bacillus Calmette Guerin (BCG results in patients with pulmonary tuberculosis (PTB. Material and Method: In 210 patients (%42,7 female, %57,6 male, mean age:40,5 ± 16,1 with smear positive and negative PTB we retrospectively analyzed the relation between radiographic findings, TST and BCG. We separated the patients into three groups as mild, moderate and severe according to their radiologic involvement and compared the radiologic extension with tuberculin skin test results. We also compared the degree of sputum smear positivity with tuberculin skin test results. Results: According to the evaluation of radiological findings of the patients, high risk is detected in 58(67,4% patients in smear-positive group and 28(32,6% patients in smear-negative group and statistically valuable relation between smear positivity and radiological findings of the patients is seen (p:0,001. According to the results of TST of the patients, high risk is detected radiologically in 53(61,6% cases of TST-negative group, 33(38,4% cases of TST-positive group and statistically valuable relation between TST results and radiological findings of the patients is seen (p:0,001. A valuable difference between BCG results and radiological findings is not seen. Discussion: It is concluded that radiology is beneficial for diagnosis especially in cases which are without bacilli and suspicious for tuberculosis and TST is shown that it can be beneficial for determining the immunity against to mycobacterium tuberculosis.

  17. Lung abscess due to Streptococcus pneumoniae simulating pulmonary tuberculosis: presentation of two cases

    Alessandro Perazzo

    2014-03-01

    Full Text Available In the past, anaerobes were the most common cause of community-acquired lung abscess; Streptococcus species were the second most common cause. In recent years, this has changed. Klebsiella pneumoniae is now most common cause of community- acquired lung abscess, although Streptococcus species remain pathogen of major importance. We present two cases of pulmonary cavitation due to Streptococcus pneumoniae which resembled pulmonary tuberculosis with regards to their history and radiological findings. These are examples of a common diagnosis presenting in an uncommon way. Our cases had some peculiarities: they had a clinical picture strongly suggestive of pulmonary tuberculosis or lung cancer rather than necrotizing infectious pneumonia in patients with no comorbidities or underlying diseases (including oral or dental pathologies. Radiological findings did not help the clinicians: pulmonary tuberculosis was the first diagnostic hypothesis in both cases. An underlying lung cancer was excluded in the first case only after invasive pulmonary procedures.

  18. Cavitating pulmonary tuberculosis in children: correlating radiology with pathogenesis

    Cavitating pulmonary tuberculosis (PTB) is generally known as a disease of adults, with children typically having features of primary PTB. To group children with PTB and cavities according to possible pathogenesis by evaluating the clinical and radiological findings. The clinical and radiological findings in ten randomly selected children with PTB and cavitations on chest radiographs were retrospectively reviewed and evaluated. Three groups emerged: group 1 (four children) had cavities, usually single and unilateral in the classic upper lobe distribution of postprimary PTB; group 2 (three children) developed progressive primary spread of disease with extensive and bilateral pulmonary cavities; and group 3 (three children) developed cavities secondary to airway obstruction by mediastinal lymph nodes with consequent distal collapse and consolidation. Children in group 1 responded well to treatment and had unremarkable recoveries. Children in group 2 were all below 2 years of age with complicated recoveries. Children in group 3 had frequent complications resulting in one fatality. Cavities in PTB in children may arise by one of three possible mechanisms with a relatively equal incidence. A study is underway to determine the incidence of cavity formation associated with mediastinal lymphadenopathy and airway obstruction. (orig.)

    Co-infection with HIV increases the morbidity and mortality associated with tuberculosis due to multiple factors including a poorly understood microbial synergy. We developed a novel small animal model of co-infection in the humanized mouse to investigate how HIV infection disrupts pulmonary containment of Mtb. Following dual infection, HIV-infected cells were localized to sites of Mtb-driven inflammation and mycobacterial replication in the lung. Consistent with disease in human subjects, we observed increased mycobacterial burden, loss of granuloma structure, and increased progression of TB disease, due to HIV co-infection. Importantly, we observed an HIV-dependent pro-inflammatory cytokine signature (IL-1β, IL-6, TNFα, and IL-8), neutrophil accumulation, and greater lung pathology in the Mtb-co-infected lung. These results suggest that in the early stages of acute co-infection in the humanized mouse, infection with HIV exacerbates the pro-inflammatory response to pulmonary Mtb, leading to poorly formed granulomas, more severe lung pathology, and increased mycobacterial burden and dissemination.

    2016-05-01

    Rifampicin (RIF) induces cytochrome P450, which in turn catalyzes drug metabolism; however, pharmacokinetic studies on this phenomenon in the Chinese population, especially in the context of disease, are limited. Therefore, we sought to establish population-based pharmacokinetic models of RIF in a Chinese population with pulmonary tuberculosis (TB). Clinical data were retrospectively collected from 54 patients with pulmonary TB and analyzed alongside RIF blood levels from 95 samples collected prior to RIF administration and between 2 and 12 hours after treatment. HPLC was used to measure serum RIF concentrations. A nonlinear mixed model used to characterize RIF pharmacokinetics and the data generated from the present study were validated using a bootstrap method. Covariates, including demographics, as well as hematological and biological indicators were analyzed. We observed a 1-compartment model with first-order absorption. Typical population values of apparent clearance (CL/F) and apparent volume of distribution (VD /F) were 4.02 L/h and 57.8 L, respectively. No covariate significantly changed the parameters of CL/F and VD . The present study may serve as a foundation for individualized therapy and offer a basis for pharmacokinetic-pharmacodynamic (PK-PD) analysis. PMID:26387492

  3. The radiological spectrum of pulmonary multidrug-resistant tuberculosis: in HIV-Negative patients

    Background: Multidrug-resistant tuberculosis is a major worldwide health problem. In countries where tuberculosis is of moderate to high prevalence, the issue of Multidrug-resistant tuberculosis carries significant importance. Multidrug-resistant tuberculosis, similar to drug-sensitive tuberculosis, is contagious. Meanwhile its treatment is not only more difficult but also more expensive with lower success rates. Regarding clinical findings, there is no significant difference between Multidrug-resistant tuberculosis and drug-sensitive tuberculosis. Therefore determination of characteristic radiological findings in cases of Multidrug-resistant tuberculosis might be of help in early detection, and hence appropriate management of this disease condition. Objective: To explain the radiological spectrum of pulmonary Multidrug-resistant tuberculosis. Patients and methods: We retrospectively evaluated the radiographic images of 35 patients with clinically-and microbiologically- proven Multidrug-resistant tuberculosis admitted to our tertiary-care tuberculosis unit over a period of 13 months. The latest chest x-ray of all patients and the conventional chest CT scan without contrast of 15 patients were reviewed by three expert radiologists who rendered consensus opinion. Results: Of the 35 patients with imaging studies, 23 (66%) were male and 12 (34%) were female. The mean±SD age of participants was 38.2±17.3 (range: 16-20) years. 33 patients were known as secondary and only 2 had primary Multidrug-resistant tuberculosis. Chest radiography revealed cavitary lesion in 80% pulmonary infiltration in 89% and nodules in 80% of the cases. Pleurisy was the rarest finding observed in only 5 (14%) patients. All of 15 chest CT scans revealed cavitation, 93% of which were bilateral and multiple. Pleural involvement was seen in 93% of patients. Conclusion: Presence of multiple cavities, especially in both lungs, nodular and infiltrative lesions, and pleural effusion are main features

    Full Text Available Abstract Background There is paucity of data on seasonal variation in pulmonary tuberculosis (TB in developing countries contrary to recognized seasonality in the TB notification in western societies. This study examined the seasonal pattern in TB diagnosis among migrant workers from developing countries entering Kuwait. Methods Monthly aggregates of TB diagnosis results for consecutive migrants tested between January I, 1997 and December 31, 2006 were analyzed. We assessed the amplitude (α of the sinusoidal oscillation and the time at which maximum (θ° TB cases were detected using Edwards' test. The adequacy of the hypothesized sinusoidal curve was assessed by χ2 goodness-of-fit test. Results During the 10 year study period, the proportion (per 100,000 of pulmonary TB cases among the migrants was 198 (4608/2328582, (95% confidence interval: 192 – 204. The adjusted mean monthly number of pulmonary TB cases was 384. Based on the observed seasonal pattern in the data, the maximum number of TB cases was expected during the last week of April (θ° = 112°; P α = 0.204 ± 0.04 of simple harmonic curve showed 20.4% difference from the mean to maximum TB cases. The peak to low ratio of adjusted number of TB cases was 1.51 (95% CI: 1.39 – 1.65. The χ2 goodness-of-test revealed that there was no significant (P > 0.1 departure of observed frequencies from the fitted simple harmonic curve. Seasonal component explained 55% of the total variation in the proportions of TB cases (100,000 among the migrants. Conclusion This regularity of peak seasonality in TB case detection may prove useful to institute measures that warrant a better attendance of migrants. Public health authorities may consider re-allocation of resources in the period of peak seasonality to minimize the risk of Mycobacterium tuberculosis infection to close contacts in this and comparable settings in the region having similar influx of immigrants from high TB burden countries

Methods The data of 80 patients suffering from pulmonary tuberculosis with diabetes were analyzed , focusing on the interaction of pulmonary tuberculosis and diabetes. Results The severity of pulmonary tuberculosis closely related with the control of blood glucose. The higher of blood glucose, the higher detection rate of smear-positive and the higher cavitation rate. The treatment effect of pulmonary tuberculosis was closely related to the control of blood glucose. Conclusion Pulmonary tuberculosis with diabetes was characterized by wide extent of disease, high rates of smear-positive and cavity and bad prognosis. The control of blood glucose was the key to its care. Actively contolling blood glucose and reasonably using antituberculosis drugs can improve recovery rate Pulmonary tuberculosis.

  6. Association of the FCN2 Gene Single Nucleotide Polymorphisms with Susceptibility to Pulmonary Tuberculosis.

    Dan-Dan Xu

    Full Text Available Ficolin-2 (FCN2 is an innate immune pattern recognition molecule that can activate the complement pathway, opsonophagocytosis, and elimination of the pathogens. The present study aimed to investigate the association of the FCN2 gene single nucleotide polymorphisms (SNPs with susceptibility to pulmonary tuberculosis (TB. A total of seven SNPs in exon 8 (+6359 C>T and +6424 G>T and in the promoter region (-986 G>A, -602 G>A, -557 A>G, -64 A>C and -4 A>G of the FCN2 gene were genotyped using the PCR amplification and DNA sequencing methods in the healthy controls group (n = 254 and the pulmonary TB group (n = 282. The correlation between SNPs and pulmonary TB was analyzed using the logistic regression method. The results showed that there were no significant differences in the distribution of allelic frequencies of seven SNPs between the pulmonary TB group and the healthy controls group. However, the frequency of the variant homozygous genotype (P = 0.037, -557 A>G; P = 0.038, -64 A>C; P = 0.024, +6424 G>T in the TB group was significantly lower than the control group. After adjustment for age and gender, these variant homozygous genotypes were found to be recessive models in association with pulmonary TB. In addition, -64 A>C (P = 0.047 and +6424 G>T (P = 0.03 were found to be codominant models in association with pulmonary TB. There was strong linkage disequilibrium (r2 > 0.80, P A site. Therefore, -557 A>G, -64 A>C and +6424 G>T SNPs of the FCN2 gene were correlated with pulmonary TB, and may be protective factors for TB. This study provides a novel idea for the prevention and control of TB transmission from a genetics perspective.

  7. Patterns of pulmonary tuberculosis on FDG-PET/CT

    Objective: This study aims to describe patterns of pulmonary tuberculosis (TB) on FDG-PET/CT. Methods: All patients with a diagnosis of TB and who underwent FDG-PET/CT between January 2009 and June 2010 were included. Clinical, biological and imaging data were reviewed. TB was proven either on bacteriological or histopathological studies (n = 13) or on a clinical and imaging basis (n = 3). Results: Sixteen patients (11 men; median age 56, range 22–84 years) were included. Two distinct patterns were identified. In the lung pattern (9/16), patients had predominantly pulmonary symptoms (6/9 patients, 67%) with a parenchymal involvement: uptakes on lung consolidation ± cavitation surrounded by micronodules. Mediastino-hilar lymph nodes were slightly enlarged (15 mm, 10–27) with moderate uptake (3.9, 2.5–13.4). In the lymphatic pattern (7/16), patients had predominantly systemic symptoms (5/7 cases, 71%) and all had extra-thoracic involvement. Mediastino-hilar lymph nodes were more enlarged (30 mm, 18–35, p = 0.03) and with higher uptake (6.8, 5.7–16.8, p = 0.034) than in the lung pattern. Conclusion: We identified two distinct patterns of pulmonary TB on FDG-PET/CT. The lung pattern related to a restricted and slight hypermetabolic infection and the lymphatic pattern related to a systemic and intense infection. Combined interpretation of PET and CT findings improves the specificity of images, especially for the lung pattern

    2006-01-01

    Pulmonary tuberculosis remains a major health problem. It is caused by Mycobacterium tuberculosis, which elicits a T-cell dependent immune response, initiated by monocytes through a large number of cytokines of which interleukin-12 is thought to play a critical role in initiation and regulation of T-helper (Th-1) like responses. To better understand the role of IL-12 in pulmonary tuberculosis patients, intracellular IL-12 in peripheral blood-derived monocytes was examined by flowcytometery. The percentage of monocytes producing IL-12 was measured after invitro stimulation of heparinized whole blood with mycobacterial protein antigens (culture filtrate). Of the 22 active tuberculosis patients, 17 were recent cases and 5 recurrent cases. Healthy controls were 14 individuals with detectable reaction to purified protein derivative (PPD+) and 14 without detectable reaction to PPD. The role of different factors affecting disease outcome such as treatment, age, gender, smoking, severity of disease and presence of other complications on the percentage of monocytes producing IL-12 was studied. Recurrent TB patients had a higher number of monocytes producing IL-12 in unstimulated cultures compared to other groups (P 0.05). It is concluded that IL-12 plays a prominent regulatory role in tuberculosis. PMID:17974150

    Full Text Available OBJECTIVE To assess the increased diagnostic yield for pulmonary tuberculosis using bronchial washing cultures compared with sputum cultures. METHODS Study conducted with 61 adults in Lima, Peru, from January 2006 to December 2007. The yield of sputum cultures was compared with the yield of acid-fast bacilli smears and cultures of bronchial washing for diagnosing pulmonary tuberculosis in suspected cases of clinical tuberculosis with negative acid fast bacilli sputum smears. RESULTS Twenty seven (95%CI 32;58 of the cases were eventually diagnosed with smear-negative pulmonary tuberculosis. Bronchial washing samples detected 23 (95%CI 72;99 of the smear-negative pulmonary tuberculosis cases compared with 15 (95%CI 37;74 for sputum cultures (p = 0.02. The incremental diagnostic yield of acid fast bacilli smear and culture of bronchial washing specimens over sputum culture was 44% (95%CI 25;65. CONCLUSIONS In function of the epidemiological context and the resources available, bronchoscopy should be deployed as part of a comprehensive work up that optimizes smear-negative pulmonary tuberculosis diagnosis and minimizes risk and costs.

    Full Text Available OBJECTIVE: To compare the performance of nested polymerase chain reaction (NPCR with that of cultures in the detection of the Mycobacterium tuberculosis complex in pulmonary and extrapulmonary specimens.METHODS: We analyzed 20 and 78 pulmonary and extrapulmonary specimens, respectively, of 67 hospitalized patients suspected of having tuberculosis. An automated microbial system was used for the identification of Mycobacterium spp. cultures, and M. tuberculosis IS6110 was used as the target sequence in the NPCR. The kappa statistic was used in order to assess the level of agreement among the results.RESULTS: Among the 67 patients, 6 and 5, respectively, were diagnosed with pulmonary and extrapulmonary tuberculosis, and the NPCR was positive in all of the cases. Among the 98 clinical specimens, smear microscopy, culture, and NPCR were positive in 6.00%, 8.16%, and 13.26%, respectively. Comparing the results of NPCR with those of cultures (the gold standard, we found that NPCR had a sensitivity and specificity of 100% and 83%, respectively, in pulmonary specimens, compared with 83% and 96%, respectively, in extrapulmonary specimens, with good concordance between the tests (kappa, 0.50 and 0.6867, respectively.CONCLUSIONS: Although NPCR proved to be a very useful tool for the detection of M. tuberculosis complex, clinical, epidemiological, and other laboratory data should also be considered in the diagnosis and treatment of pulmonary and extrapulmonary tuberculosis.

    Surgical emphysema as a presenting manifestation of pulmonary tuberculosis in the absence ofpneumothorax and/or pneumomediastinum is not yet known. We report one such case in which surgicalemphysema was probably the result of rupture of a pulmonary cavity into subcutaneous tissue resultingfrom caverno-pleuro-cutaneous fistula.

  13. Radiological profile of pulmonary tuberculosis in HIV: concerning 171 observations in Kinshasa

    This prospective descriptive study was conducted in Depistage center of the Tuberculosis treatment of Kabinda during a period of three months, had as objectives to study the radiological profile of pulmonary tuberculosis in HIV and HIV- patients, then to compare the frequency of different radiological abnormalities between the two groups to determine some characteristics of co-infection HIV/TP+. Among 171 patients with contagious pulmonary tuberculosis, 50 patients had positive serology for HIV, a prevalence of 29,2%. The intrathoracic lymph nodes, localized lesions only in the lower field were more observed in HIV, as well as pleurisy and the absence of radiological abnormality. The only one case of miliary was HIV positive. By contrast, excavations and localized lesions in the upper field were predominant in HIV-. Atypical radiological manifestations of pulmonary tuberculosis were more common in patients with HIV infection.

    The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV) and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001), showed a higher frequency of weight loss >10 kilos (p tuberculosis (p = 0.001). Treatment failure was more common in those who were HIV positive (p extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

    Objective:To observe the influence of levofloxacin on soluble selection, interleukin, adhesion molecule and pulmonary surfactant protein of patients with pulmonary tuberculosis. Methods:A total of 50 patients with pulmonary tuberculosis who had been treated in our hospital from March 2014 to April 2015 were randomly divided into the control group (conventional treatment) and the observation group (conventional treatment plus levofloxacin). Each group had 25 cases. Then, the soluble selection,interleukin,adhesion molecule and pulmonary surfactant protein levels of the two groups at the second, fourth and sixth months before and after treatment were compared. Results:Before treatment, the differencess of the levels of the soluble selection, interleukin, adhesion molecule and pulmonary surfactant protein of the two groups were significant (P>0.05), while the detection levels of all the aspects of the observation group at the second, fourth and sixth months after treatment were all significantly lower than those of the control group (P<0.05). The detection results of the two groups at the second, fourth and sixth months after treatment showed significant differences. Conclusions:Lvofloxacin has significant effect on the soluble selection, interleukin, adhesion molecule and pulmonary surfactant protein of patients with pulmonary tuberculosis.

    • BACKGROUND: Despite recent technologic improvements in identifying mycobacterium tuberculosis, we are still facing problems in rapid diagnosis of tuberculosis. The objective of this study is to determine the diagnostic value of a new rapid screening test (Patho-TB™ for diagnosis of pulmonary tuberculosis.
    • METHODS: Between September 2006 to August 2007, 178 patients were enrolled in the study who were finally classified into two groups; a group of documented pulmonary tuberculosis (n = 67 and a group of non-tuberculous pulmonary infection (n = 111. Patho-TB™ test, Ziehl-Neelsen staining and culture were done on all specimens.
    • RESULTS: Of all, 43 patients with pulmonary tuberculosis were sputum smear positive for acid fast bacilli and the rest were smear negative. Mean age of the patients was 59.8 ± 16.1 years and 44% of them were men. The results of Patho- TB™ test were positive in 40 of smear positive and 20 of smear negative tuberculous patients and 33 cases of nontuberculous control group. The sensitivity, specificity, positive and negative predictive values and accuracy of Patho- TB™ test were estimated 89.5%, 70.2%, 64.5%, 91.7% and 77.5%, respectively.
    • CONCLUSIONS: According to the present study it would be suggested that Patho-TB™ test could be a rapid and inexpensive method for diagnosis of pulmonary tuberculosis, given by its high sensitivity and negative predictive value. Concerning the high number of false positive results, using a confirmatory diagnostic procedure is mandatory.

    Data on genotypic diversity of Mycobacterium tuberculosis complex (MTBC) is important to understand its epidemiology, human adaptation, clinical phenotypes, and drug resistance. This study aimed to characterize MTBC clinical isolates circulating in a predominantly pastoralist area in Ethiopia, a country where tuberculosis is the second leading cause of mortality. Culture of sputum samples collected from a total of 325 pulmonary TB suspects was done to isolate MTBC. Spoligotyping was used to characterize 105 isolates from culture positive slopes and the result was compared with an international database. Forty-four spoligotype patterns were observed to correspond to 35 shared-types (SITs) containing 96 isolates and 9 orphan patterns; 27 SITs containing 83 isolates matched a preexisting shared-type in the database, whereas 8 SITs (n = 13 isolates) were newly created. A total of 19 SITs containing 80 isolates were clustered within this study (overall clustering of 76.19%). Three dominant lineages (T, CAS, and Manu) accounted for 76.19% of the isolates. SIT149/T3-ETH was one of the two most dominant sublineages. Unlike previous reports, we show that Manu lineage strains not only constitute a dominant lineage, but are also associated with HIV infection in Afar region of Ethiopia. The high level of clustering suggests the presence of recent transmission that should be further studied using additional genotyping markers. PMID:24734230

    Full Text Available Abstract Background Pulmonary tuberculosis (TB is a highly lethal infectious disease and early diagnosis of TB is critical for the control of disease progression. The objective of this study was to profile a panel of serum microRNAs (miRNAs as potential biomarkers for the early diagnosis of pulmonary TB infection. Methods Using TaqMan Low-Density Array (TLDA analysis followed by quantitative reverse transcriptase polymerase chain reaction (qRT-PCR validation, expression levels of miRNAs in serum samples from 30 patients with active tuberculosis and 60 patients with Bordetella pertussis (BP, varicella-zoster virus (VZV and enterovirus (EV were analyzed. Results The Low-Density Array data showed that 97 miRNAs were differentially expressed in pulmonary TB patient sera compared with healthy controls (90 up-regulated and 7 down-regulated. Following qRT-PCR confirmation and receiver operational curve (ROC analysis, three miRNAs (miR-361-5p, miR-889 and miR-576-3p were shown to distinguish TB infected patients from healthy controls and other microbial infections with moderate sensitivity and specificity (area under curve (AUC value range, 0.711-0.848. Multiple logistic regression analysis of a combination of these three miRNAs showed an enhanced ability to discriminate between these two groups with an AUC value of 0.863. Conclusions Our study suggests that altered levels of serum miRNAs have great potential to serve as non-invasive biomarkers for early detection of pulmonary TB infection.

  19. Arterial embolization for management of hemoptysis in pulmonary tuberculosis : factors of rebleeding

    To evaluate the effectiveness of arterial embolization in reducing hemoptysis in pulmonary tuberculosis, and rebleeding factors after embolization. Fifty-nine patients with massive or recurrent hemoptysis from pulmonary tuberculosis were underwent percutaneous transcatheter embolotherapy and thirteen were subsequently operated on. In 46 patients, we retrospectively analyzed on plain chest PA the extent of pulmonary tuberculosis lesions, the period from initial diagnosis to embolization, and angiographic findings. The extent of lesions shown on plain chest PA were classified into minimal, moderately advanced, and far advanced. If there was no evidence of rebleeding after the first embolization,this was regarded as initial success in the control of hemoptysis. Angiographic findings were classified into hypervascularity, shunt, aneurysmal dilatation, and extravasation. Using the chi-square test, differences in these findings between rebleedig and non-rebleeding cases were anlysed. Immediate control of hemoptysis was achieved in 27 (58.7%) of 46 patients. Hemoptysis recurred in 19 (41.3%) of 46 patients followed up. Rebleeding cases showed more nonbronchial systemic collateral vessels and shunt than non-rebleeding cases (p<0.05). More advanced lesions of pulmonary tuberculosis on plain chest PA showed an increased rebleeding rate after embolization, but this was not statistically significant. There was no correlation between the period from initial diagnosis of pulmonary tuberculosis to embolization and the rate of rebleeding. But the longer the period, the greater the number of nonbronchial systemic collateral vessels. In cases with more advanced lesions of pulmonary tuberculosis on plain chese PA and a long period from initial diagnosis of pulmonary tuberculosis to embolization, angiographic findings showed numerous nonbronchial systemic collateral vessels but increases in the rebleeding rate were statistically not significant. The greater the number of nonbronchial

    2012-01-01

    Full Text Available A case of pulmonary tuberculosis caused by Mycobacterium tuberculosis was diagnosed in a horse. Clinical evaluation performed prior to euthanasia did not suggest tuberculosis, but postmortem examination provided pathological and bacteriological evidence of mycobacteriosis. In the lungs, multiple tuberculoid granulomas communicating with the bronchiolar lumen, pleural effusion, and a granulomatous lymphadenitis involving mediastinal and tracheobronchial lymph nodes were found. Serologic response to M. tuberculosis antigens was detected in the infected horse, but not in the group of 42 potentially exposed animals (18 horses, 14 alpacas, 6 donkeys, and 4 dogs which showed no signs of disease. Diagnosis of tuberculosis in live horses remains extremely difficult. Four of 20 animal handlers at the farm were positive for tuberculous infection upon follow-up testing by interferon-gamma release assay, indicating a possibility of interspecies transmission of M. tuberculosis.

  2. CT and pathologic correlation acute miliary pulmonary tuberculosis

    Objective: To elucidate the CT characteristics and pathology of acute miliary pulmonary tuberculosis (AMPT). Methods: The CT features of AMPT in 25 cases were analyzed retrospectively, and the CT features in HIV-seronegative and HIV-seropositive patients were compared by 2-sided exact probability Chi-square test. Two lung specimens were inflated and fixed by Heitzman's method. HRCT scans, gross specimen section (80-150 μm) and histologic section (5 μm) were performed on dry lung specimens and CT-pathologic correlation was conducted. The distribution of micronodules in the secondary lobule on HRCT and pathology in one specimen was evaluated by Chi-square test. Results: Twenty five patients with AMPT were included in this study, including 11 HIV-seropositive patients and 14 HIV- seronegative patients. HRCT showed diffuse micronodules randomly distributed throughout both lungs in 25 patients, and ground-glass opacity (17 patients) was the predominant complicated finding. Coalescence of nodules and consolidation in HIV-seropositive patients (5 and 6 patients) were markedly higher than that in HIV-seronegative patients (none). In lung specimens, most nodules located in the lung parenchyma between the central bronchovascular bundle and the perilobular structures (792 and 560 nodules), which located in the interlobular septum pathologically. The distribution of micronodules in the secondary lobule showed on HRCT (1060 nodules) and pathology (864 nodules) was not significantly difference (χ2=2.814, P>0.05) . HRCT showed ground-glass opacities when ARDS occurred, which were pulmonary edema, inflammation and hyaline membrane on alveolar wall pathologically. Conclusions: The HRCT characteristic of nodule distribution in AMPT is random. ARDS should be suspected when diffuse ground-glass opacities appear on HRCT. (authors)

  3. Pulmonary spheral tuberculosis: features and clinical significance of spiral dynamic CT

    Objective: To assess the features and clinical significance of spiral dynamic CT in patients with pulmonary spheral tuberculosis. Methods: The 54 foci in 42 patients with pulmonary spheral tuberculosis were studied. Thin-sections at 2 mm thickness and 2 mm interval through the nodular center were obtained before and after administration of contrast material. Results: In 54 pulmonary spheral tuberculosis, maximum enhanced CT value in 51 (94.4%, 51/54) foci was less than 20 HU, and more than 20 HU in the other 3(5.6%, 3/54) foci. 27(50.0%, 27/54) foci showed no any enhancement, 24, (44%, 24/54) foci showed capsular enhancement, 1(1.9%, 1/54) focus showed peripheral enhancement and 2(3.7%, 2/54) foci showed extensive enhancement. The accuracy of the correct diagnosis was 25.9% in terms of plain CT and 94.4% in terms of enhanced CT scanning. The difference was significant (x2 = 50.1, P < 0.05). The curative effect of extensive enhanced foci and peripheral enhanced foci was optimal, capsular enhanced foci was second, and non-enhanced foci was barely satisfactory. Conclusion: Spiral dynamic CT technique may improve the accuracy of diagnosing pulmonary spheral tuberculosis. No enhancement and/or capsular enhancement were suggestive of tuberculosis. The enhancing character of foci might contribute to assess the curative effect of anti-tuberculosis

  4. Comparison of sputum acid-fast culture and chest radiography in pulmonary tuberculosis

    While it is still a common practice of some clinicians to rely on chest radiography examination alone for the diagnosis of pulmonary tuberculosis, others still claim that absolute diagnosis of tuberculosis can firmly be established by bacteriological examination from secretions or tissues of the infected host. This study will evaluate the relationship between radiographic findings (CXR) and the likelihood of finding tubercle bacilli on sputum acid-fast bacilli (AFB) culture in pulmonary tuberculosis at Lung Center of the Philippines. Of 41 individuals who submitted their sputum for AFB culture, tubercle bacilli in the sputum was shown in 25 (60%) of cases and no growth of tubercle bacilli in 16 (40%) of cases. Chest radiography reading revealed tuberculosis in 100% of cases, of which when classified further, 22 (54%) has fibrohazed or hazy infiltrates on their CXR, 7 (17%) has cavitations or interpreted as moderate or far advanced TB, 12 (29%) has fibroid, nodular infiltrates or densities. In patients radiologically diagnosed as PTB minimal, sputum culture revealed tubercle bacilli in 15 (57%) among moderate, far advanced tuberculosis, and 6 (50%) among those with inactive or old tuberculosis. Therefore, the probability of detecting tubercle bacilli in pulmonary tuberculosis is not greatly influenced by radiographic findings. (auth.). 11 refs.; 2 figs.; 2 tabs

    2010-06-01

    Full Text Available Abstract Background The prevalence of pulmonary tuberculosis among college students in Shaanxi is high. Although tuberculosis leaves much psychological and social impact on patients, little is known about its impact on college students. The objective of this study is to explore the experiences and psychological process of college students with pulmonary tuberculosis in Shaanxi, China. Methods 17 college students with pulmonary tuberculosis were recruited purposively from 9 colleges in Shaanxi. In-depth interviews were conducted to collect data and a thematic framework analysis was used. Results The participants reported that pulmonary tuberculosis deeply influenced their mental health. They were fearful to the nature of pulmonary tuberculosis at the stage of diagnosis, anxious about the illness before the period of diagnosis and the early week of the treatment, excessive worry immediately before the first recheck. They expected an early full recovery, bored on tedious treatment life and worried about future heath and prospects during the whole treatment phase. Their daily life was also influenced, namely discontinued studies, isolation and increased financial burden. They also reported that they could get strong supports from family members, while little supports from healthcare workers and their friends. Conclusions The participants' psychological pressure was significant during the treatment. In addition, there was serious conflict between treatment and study; social support provided for them was insufficient. Healthcare workers should provide psychological support for college students with pulmonary tuberculosis according to the psychological characteristics and offer social support through strengthening communication with them. Colleges should follow governmental policies on TB exactly and provide opportunities for the patients to continue their studies.

  6. Radiological patterns of childhood pulmonary tuberculosis in Khartoum state

    This hospital based study was undertaken to determine the commonest radiological features of childhood pulmonary tuberculosis in Khartoum, and to correlate these features with the clinical symptoms and laboratory investigations. A total of hundred patients were selected from referred clinics and the paediatric wards (inpatients) of three teaching hospitals in Khartoum, during the period february 95 to april 96. Almost all the families were from low socio economic status. The peak age incidence was at (7, 8, 10) years; 50% of children had received BCG vaccination and history of contact with TB was positive in 35%. Mantoux test was positive in 79% and four cases had smear-positive sputum for AAFB. The most frequent lesion on chest radiography was lemphadenopathy in 67% of cases followed by multiple lesions which were present in 65% of cases. Consolidation was present in 49 cases , 38 showed unilateral changes, while 11 showed bilateral changes. The right and particularly the right middle and lower lobes were more frequently affected. Seven patients had pleural effusion which was sided in five, left sided in one and bilateral in one. Cavitation was present in eight cases, broncho-pneumonic changes in three and only one case had miliary mottling. Positive mantoux test and chest x-ray were present in 72 patients, while all cases with negative mantoux and negative sputum smear showed significant radiological findings. (Author)

  7. Microbiome diversity in the sputum of patients with pulmonary tuberculosis.

    TB is a worldwide pandemic. India has the highest burden of TB, with WHO statistics for 2013 giving an estimated incidence figure of 2.1 million cases for India out of a global incidence of 9 million. Microbiota have been shown to be associated with many disease conditions; however, only few studies have been reported for microbiota associated with TB infection. For the first time, we characterized the composition of microbiota of TB patients of India, using high-throughput 16S rRNA gene sequencing and compared it with healthy controls. Phylum-level analysis showed that the relative abundance of Firmicutes and Actinobacteria was significantly higher in TB samples and Neisseria and Veillonella were two dominant genera after Streptococcus. In our study, significantly different core genera in TB and normal population were found as compared with the reported studies. Also, the presence of diverse opportunistic pathogenic microbiota in TB patients increases the complexity and diversity of sputum microbiota. Characterization of the sputum microbiome is likely to provide important pathogenic insights into pulmonary tuberculosis. PMID:27142586

    Objectives Adjunctive host-directed therapy is emerging as a new potential approach to improve the outcome of conventional antimicrobial treatment for tuberculosis (TB). We tested the ability of a phosphodiesterase-4 inhibitor (PDE4i) CC-11050, co-administered with the first-line anti-TB drug isoniazid (INH), to accelerate bacillary killing and reduce chronic inflammation in the lungs of rabbits with experimental Mycobacterium tuberculosis (Mtb) infection. Methods A rabbit model of pulmonary TB that recapitulates the pathologic manifestations seen in humans was used. Rabbits were infected with virulent Mtb by aerosol exposure and treated for eight weeks with INH with or without CC-11050, starting at four weeks post infection. The effect of CC-11050 treatment on disease severity, pathology, bacillary load, T cell proliferation and global lung transcriptome profiles were analyzed. Results Significant improvement in bacillary clearance and reduced lung pathology and fibrosis were noted in the rabbits treated for eight weeks with INH + CC-11050, compared to those treated with INH or CC-11050 only. In addition, expression of host genes associated with tissue remodeling, tumor necrosis factor alpha (TNF-α) regulation, macrophage activation and lung inflammation networks was dampened in CC-11050-treated, compared to the untreated rabbits. Conclusions Adjunctive CC-11050 therapy significantly improves the response of rabbits with experimental pulmonary TB to INH treatment. We propose that CC-11050 may be a promising candidate for host directed therapy of patients with pulmonary TB, reducing the duration and improving clinical outcome of antibiotic treatment.

  11. Mycobacterium tuberculosis Zinc Metalloprotease-1 Elicits Tuberculosis-specific Humoral Immune Response Independent of Mycobacterial Load in Pulmonary and Extra-Pulmonary Tuberculosis Patients

    Mani Harika eVemula

    2016-03-01

    Full Text Available Conventionally, facultative intracellular pathogen, Mycobacterium tuberculosis (M.tb, the tuberculosis (TB causing bacilli in human is cleared by cell-mediated immunity (CMI with CD4+ T cells playing instrumental role in protective immunity, while antibody-mediated immunity (AMI is considered non-protective. This longstanding convention has been challenged with recent evidences of increased susceptibility of hosts with compromised AMI and monoclonal antibodies conferring passive protection against TB and other intracellular pathogens. Therefore, novel approaches towards vaccine development include strategies aiming at induction of humoral response along with CMI. This necessitates the identification of mycobacterial proteins with properties of immunomodulation and strong immunogenicity. In this study, we determined the immunogenic potential of M.tb Zinc metalloprotease-1 (Zmp1, a secretory protein essential for intracellular survival and pathogenesis of M.tb. We observed that Zmp1 was secreted by in vitro grown M.tb under granuloma-like stress conditions (acidic, oxidative, iron deficiency and nutrient deprivation and generated Th2 cytokine microenvironment upon exogenous treatment of Peripheral Blood Mononulear Cells (PBMCs with recombinant Zmp1 (rZmp1. This was supported by recording specific and robust humoral response in TB patients in a cohort of 295. The anti-Zmp1 titers were significantly higher in TB patients (n=121 as against healthy control (n=62, household contacts (n=89 and non-specific infection controls (n=23. A significant observation of the study is the presence of equally high titers of anti-Zmp1 antibodies in a range of patients with high bacilli load (sputum bacilli load of 300+ per mL to paucibacillary smear-negative pulmonary tuberculosis (PTB cases. This clearly indicated the potential of Zmp1 to evoke an effective humoral response independent of mycobacterial load. Such mycobacterial proteins can be explored as antigen

    Tuberculosis is characterized by extensive destruction and remodelling of the pulmonary extracellular matrix. Stromal cell-derived matrix metalloproteinases (MMPs) are implicated in this process and may be a target for adjunctive immunotherapy. We hypothesized that MMPs are elevated in bronchoalveolar lavage fluid of tuberculosis patients and that antimycobacterial agents may have a modulatory effect on MMP secretion. Concentrations of MMP-1, -2, -3, -7, -8, and -9 were elevated in the bronch...

    Full Text Available Background: tuberculosis program is a priority for the National Health System in Cuba. The difficulties encountered in dealing with the disease are associated, directly or indirectly, to a restricted knowledge management by the health system. Objective: to implement a geographical information system to manage information on pulmonary tuberculosis. Methods: retrospective, descriptive and correlational study conducted between January 1, 1996 and December 31, 2007. It included the 155 new cases of pulmonary tuberculosis in 15 years old patients and on in the province of Cienfuegos. MapInfo 8.5 software was used to design the geographical information system. Theoretical, empirical and statistical methods were combined. Results: the elimination of the geographical aspect as an obstacle for carrying out preventive actions established in the program and for the stratification of pulmonary tuberculosis according to its incidence in districts and neighbourhoods of the city. Conclusions: the designed geographical information system is an auxiliary technological tool that improves information management on pulmonary tuberculosis in Cienfuegos as the basis for a variety of analysis and the generation of new knowledge.

    Editors' Summary Background Every year, nearly 10 million people develop tuberculosis—a contagious bacterial infection that usually affects the lungs (pulmonary tuberculosis)—and about 1.7 million people die from the disease. Mycobacterium tuberculosis, which causes tuberculosis, is spread in airborne droplets when people with the disease cough or sneeze. Thus, to control tuberculosis, it is essential that infected individuals are rapidly identified and treated. The “gold standard” diagnostic...

  19. Pulmonary Alveolar Proteinosis and tuberculosis in a diabetic patient: a rare or a seldom diagnosed association

    Pereira-Silva J.L.

    2002-01-01

    Full Text Available A case of Pulmonary Alveolar Proteinosis (PAP, in association with tuberculosis, is described in a 35-year-old diabetic patient. Lung biopsy showed an intra-alveolar accumulation of PAS-positive material, and multifocal granulomas compatible with tuberculosis. The bronchoalveolar culture was positive for Mycobacterium tuberculosis. PAP results from an imbalance of the mechanisms that regulate the homeostasis of the surfactant, where specific proteins are involved, especially SP-A and SP-D, the cytokines, IL-10 and GM-CSF, in addition to alveolar macrophages and type-II pneumocytes. Chemotaxis and phagocytic capacity are reduced. PAP and diabetes share several immunological disfunctions that may increase the risk for tuberculosis. Although there are no controlled studies, the diagnosis of PAP in diabetic patients with tuberculosis must be considered.

  20. Association of Pulmonary Tuberculosis and Diabetes in Mexico: Analysis of the National Tuberculosis Registry 2000-2012.

    Guadalupe Delgado-Sánchez

    Full Text Available Tuberculosis (TB remains a public health problem in Mexico while the incidence of diabetes mellitus type 2 (DM has increased rapidly in recent years.To describe the trends of incidence rates of pulmonary TB associated with DM and not associated with DM and to compare the results of treatment outcomes in patients with and without DM.We analysed the National Tuberculosis Registry from 2000 to 2012 including patients with pulmonary TB among individuals older than 20 years of age. The association between DM and treatment failure was analysed using logistic regression, accounting for clustering due to regional distribution.In Mexico from 2000 to 2012, the incidence rates of pulmonary TB associated to DM increased by 82.64%, (p<0.001 in contrast to rates of pulmonary TB rate without DM, which decreased by 26.77%, (p<0.001. Patients with a prior diagnosis of DM had a greater likelihood of failing treatment (adjusted odds ratio, 1.34 (1.11-1.61 p<0.002 compared with patients who did not have DM. There was statistical evidence of interaction between DM and sex. The odds of treatment failure were increased in both sexes.Our data suggest that the growing DM epidemic has an impact on the rates of pulmonary TB. In addition, patients who suffer from both diseases have a greater probability of treatment failure.

    Full Text Available Objective: Pulmonary tuberculosis is an important health problem in pediatric patients. The aim of this study is to evaluate the epidemiological and clinical signs and treatment results of the children with pulmonary tuberculosis. Methods:Hospital records of 85 children with pulmonary tuberculosis which were diagnosis in Dicle University Medical Faculty, Pediatric Pulmonology Department, between the period of January 2008 and December 2013,were retrospectively reviewed. Results: Of 85 patients, 51.7% were girls with a mean age of 9.84±4.66 years (6 months-18 years.Ratio of patients that aged less than 5 years was 22.3%. The most prominent complaints were cough (81.2%, fever (55.2%, inappetence (47.1%, night sweats (38.8%, and weight lost (32.9 %. Sixty five of the patients (76.4 % had a history of contact with adult patients with tuberculosis. BCG vaccine scarring was present in 70.6% of patients. Tuberculin skin test reactivity was present in 75.3%. Hilar lympadenomegaly (58.8%, primary focuscalsification (37.6%, and parenchymal infiltration (32.9% were the most common radiographic findings. Conclusion: Pulmonary tuberculous is not a rare entity and remains an important infectious disease in children in our country. Early diagnosis and treatment of children with pulmonary uberculosis is important to protect late symptoms and to prevent contamination of healthy people.

    Full Text Available ABSTRACTBACKGROUND: Questionnaire and spirometry were applied to post-tuberculosis indigenous and non-indigenous individuals from Dourados, Brazil, to investigate the prevalence of chronic respiratory symptoms and pulmonary dysfunction.METHODS:This was a cross-sectional study in cured tuberculosis individuals as reported in the National System on Reportable Diseases (SINAN from 2002 to 2012.RESULTS:One hundred and twenty individuals were included in the study and the prevalence of chronic respiratory symptoms was 45% (95% CI, 34-59%. Respiratory symptoms included cough (28%, sputum (23%, wheezing (22% and dyspnea (8%. These symptoms were associated with alcoholism, AOR: 3.1 (1.2-8.4; less than 4 years of schooling, AOR: 5.0 (1.4-17.7; and previous pulmonary diseases, AOR: 5.4 (1.7-17.3. Forty-one percent (95% CI, 29-56 had pulmonary disorders, of which the most prevalent were obstructive disorders (49%, followed by obstructive disorder with reduced forced vital capacity disorders (46% and restrictive disorders (5%. The lifestyle difference could not explain differences in chronic symptoms and/or the prevalence of pulmonary dysfunction.CONCLUSION:The high prevalence of chronic respiratory symptoms and pulmonary dysfunction in post-tuberculosis patients indicates a need for further interventions to reduce social vulnerability of patients successfully treated for tuberculosis.

  3. Trace elements status of pulmonary tuberculosis patients compared with healthy voluntaries

    Trace elements have important contribution to immune function. The objective of this study was to compare the Iron, Copper and Zinc levels of patients with active Pulmonary Tuberculosis (TB) and healthy subjects using X-ray Total Reflection Fluorescence Spectrometry. The study group was formed by men with active TB hospitalized on the Ary Parreiras State Institute of diseases of the chest and on the Santa Maria State Hospital, Rio de Janeiro, Brazil. The control group was formed by healthy men of Military Academy Fire Dom Pedro II, Rio de Janeiro, Brazil. The measurements of trace elements were performed at XRF beam line at Brazilian Synchrotron Light, Campinas, Sao Paulo. The results show that serum iron concentration was higher in control group than in study group. Besides that, serum copper concentration was higher in control group than in study group. According to the literature higher levels of copper are observed in infectious diseases like tuberculosis. In the case of the serum zinc concentration no statistical difference was observed between the two groups studied. (author)

    2016-01-01

    Full Text Available Background. Biomarkers to distinguish latent from active Mycobacterium (M. tuberculosis infection in clinical practice are lacking. The urinary neopterin/creatinine ratio can quantify the systemic interferon-gamma effect in patients with M. tuberculosis infection. Methods. In a prospective observational study, urinary neopterin levels were measured by enzyme linked immunosorbent assay in patients with active tuberculosis, in people with latent M. tuberculosis infection, and in healthy controls and the urinary neopterin/creatinine ratio was calculated. Results. We included a total of 44 patients with M. tuberculosis infection and nine controls. 12 patients had active tuberculosis (8 of them culture-confirmed. The median age was 15 years (range 4.5 to 49. Median urinary neopterin/creatinine ratio in patients with active tuberculosis was 374.1 micromol/mol (129.0 to 1072.3, in patients with latent M. tuberculosis infection it was 142.1 (28.0 to 384.1, and in controls it was 146.0 (40.3 to 200.0, with significantly higher levels in patients with active tuberculosis (p<0.01. The receiver operating characteristics curve had an area under the curve of 0.84 (95% CI 0.70 to 0.97 (p<0.01. Conclusions. Urinary neopterin/creatinine ratios are significantly higher in patients with active tuberculosis compared to patients with latent infection and may be a significant predictor of active tuberculosis in patients with M. tuberculosis infection.

  6. Mouse model of pulmonary cavitary tuberculosis and expression of matrix metalloproteinase-9

    Alvaro A. Ordonez

    2016-07-01

    Full Text Available Cavitation is a key pathological feature of human tuberculosis (TB, and is a well-recognized risk factor for transmission of infection, relapse after treatment and the emergence of drug resistance. Despite intense interest in the mechanisms underlying cavitation and its negative impact on treatment outcomes, there has been limited study of this phenomenon, owing in large part to the limitations of existing animal models. Although cavitation does not occur in conventional mouse strains after infection with Mycobacterium tuberculosis, cavitary lung lesions have occasionally been observed in C3HeB/FeJ mice. However, to date, there has been no demonstration that cavitation can be produced consistently enough to support C3HeB/FeJ mice as a new and useful model of cavitary TB. We utilized serial computed tomography (CT imaging to detect pulmonary cavitation in C3HeB/FeJ mice after aerosol infection with M. tuberculosis. Post-mortem analyses were performed to characterize lung lesions and to localize matrix metalloproteinases (MMPs previously implicated in cavitary TB in situ. A total of 47-61% of infected mice developed cavities during primary disease or relapse after non-curative treatments. Key pathological features of human TB, including simultaneous presence of multiple pathologies, were noted in lung tissues. Optical imaging demonstrated increased MMP activity in TB lesions and MMP-9 was significantly expressed in cavitary lesions. Tissue MMP-9 activity could be abrogated by specific inhibitors. In situ, three-dimensional analyses of cavitary lesions demonstrated that 22.06% of CD11b+ signal colocalized with MMP-9. C3HeB/FeJ mice represent a reliable, economical and tractable model of cavitary TB, with key similarities to human TB. This model should provide an excellent tool to better understand the pathogenesis of cavitation and its effects on TB treatments.

  7. Computed Tomography in the study of pulmonary tuberculosis

    The authors carried out a retrospective study on 4 years' work on a series of patients with proved active tuberculosis examined in the Departments of Bronchopneumology and Infectious Disease of the Arezzo Civil Hospital. The population was heterogenerous from the immunologic viewpoint. This paper compared the effectiveness of Computed Tomography (CT) with that of conventional chest radiography (CR) in the diagnosis and prognosis of tuberculosis. All patients underwent chest CR in double projection and conventional CT studies of the chest; 16 patients were also submitted to high resolution CT (HRCT). Consolidation was the most frequent parenchymal lesion in immunocompetent patients; it was often associated with cavitation, with no clear topographic prevalence in the upper lobes. Pleural effusion, as the only sign of disease and with empyema features, was found in 10 immunocompetent patients. No predominant pattern was found in the other two groups, even though intrathoracic adenopathies were relatively more common in the immigrants while micronodular images and cavitations were more common in the immunodeficient subjects. Finally, chest CR always depicted the signs of pneumopathy in progress. Conventional CT was more accurate in the spatial definition of pleuroparenchymal lesions and demonstrated more nodular lesions and/or infiltrating lesions which were often masked by scars, bymassive pleural effusions or by calcific fibrothorax. Ct also demonstrated adenophatic mediastinal involvement, showed empyemic pleural collections and confirmed fistulas in calcific fibrothorax subjects. Moreover, HRCT depicted centrilobular micronodular images which are often ill-defined and poorly or not recognizable at CR but are signs of tuberculous infection spread along the distal airways. Posttreatment follow-up confirmed clinical recovery showing markedly and progressively fewer nodular densities

    Objectives To examine the relationship between cigarette smoking and incidence and mortality rates of pulmonary tuberculosis (TB) and treatment outcomes. Materials From 1995-2010, we analyzed data from 1062 patients with TB and from 2001-2004, 2951 contacts in Southern Mexico. Patients with acid-fast bacilli or Mycobacterium tuberculosis in sputum samples underwent epidemiological, clinical and mycobacteriological evaluation and received treatment by the local DOTS program. Results Consumers of 1-10 (LS) or 11 or more (HS) cigarettes per day incidence (1.75 and 11.79) and mortality (HS,17.74) smoker-nonsmoker rate ratios were significantly higher for smokers. Smoker population was more likely to experience unfavorable treatment outcomes (HS, adjusted OR 2.36) and retreatment (LS and HS, adjusted hazard ratio (HR) 2.14 and 2.37). Contacts that smoked had a higher probability of developing active TB (HR 2.38) during follow up. Conclusions Results indicate the need of incorporating smoking prevention and cessation, especially among men, into international TB control strategies. PMID:22982014

    2003-06-01

    Full Text Available Introduction: In the patients with smear-positive pulmonary tuberculosis (TB bacteriologic assessment of sputum for detection of acid bacilli (AFB Has essential role. This evaluation is accomplished by direct sputum smear & sputum culture. These examinations must be done in regular and preferably monthly after beginning of treatment. These tests have two important aims, including, determining of treatment efficacy & duration of isolation."nMethods and Materials: Most of the studies have that classic six month regimen led to sputum smear conversion & negative sputum culture in 85% of patient. This treatment regimen has two phases, including, attack phase and maintenance phase. In the attack phase we use four drugs, including, Isoniazid (INH, Rifampin (RMP, Pyrazinamide (PZA and Ethambutol (EMB for the first 2 months and if necessary until the end of third month. In the maintenance phase we use INH and Rif for the remaining of treatment course. The main objectives of this study were to determine the time needed for smear conversion and assessment of probable factors which may influence the smear conversion until 4 months after beginning of therapy. The factors that were assessed, were, Age, nationality, sex, clinical symptoms, underlying diseases, chest radiography (number of cavities, smoking, drug abuse and concentration of AF13 in the sputum Generally, we did this cross sectional study on the patient's records, who had been observed in Imam Khomeni Hospital, west health service center and masih daneshvary hospital between."nResults: This study showed that from totally 218 patients, 138(74.6% patients had sputum conversion at the first 2 months of treatment and until the end of 3rd & 4th month this rate reached to 83.3% respectively. So in the end of fourth month only 32(14.7% patients did not show sputum smear conversion. On the other hand this study showed that two factors including presence of cavities in chest radiography

    2005-02-01

    Full Text Available Abstract Background The key elements in tuberculosis (TB control are to cure the individual patient, interrupt transmission of TB to others and prevent the tubercle bacilli from becoming drug resistant. Incomplete treatment may result in excretion of bacteria that may also acquire drug resistance and cause increased morbidity and mortality. Treatment outcome results serves as a tool to control the quality of TB treatment provided by the health care system. The aims of this study were to evaluate the treatment outcome for new cases of culture positive pulmonary TB registered in Norway during the period 1996–2002 and to identify factors associated with non-successful treatment. Methods This was a register-based cohort study. Treatment outcome was assessed according to sex, birthplace, age group, isoniazid (INH susceptibility, mode of detection and treatment periods (1996–1997, 1998–1999 and 2000–2002. Logistic regression was also used to estimate the odds ratio for treatment success vs. non-success with 95% confidence interval (CI, taking the above variables into account. Results Among the 655 patients included, the total treatment success rate was 83% (95% CI 80%–86%. The success rates for those born in Norway and abroad were 79% (95% CI 74%–84% and 86% (95% CI 83%–89% respectively. There was no difference in success rates by sex and treatment periods. Twenty-two patients (3% defaulted treatment, 58 (9% died and 26 (4% transferred out. The default rate was higher among foreign-born and male patients, whereas almost all who died were born in Norway. The majority of the transferred out group left the country, but seven were expelled from the country. In the multivariate analysis, only high age and initial INH resistance remained as significant risk factors for non-successful treatment. Conclusion Although the TB treatment success rate in Norway has increased compared to previous studies and although it has reached a reasonable target

    Presentation of pulmonary tuberculosis (PTB) as acute pneumonia in severely-malnourished and HIV-positive children has received very little attention, although this is very important in the management of pneumonia in children living in communities where TB is highly endemic. Our aim was to identify confirmed TB in children with acute pneumonia and HIV infection and/or severe acute malnutrition (SAM) (weight-for-length/height or weight-for-age z score Web of Science in April 2013 for the period from January 1974 through April 2013. We included only those studies that reported confirmed TB identified by acid fast bacilli (AFB) through smear microscopy, or by culture-positive specimens from children with acute pneumonia and SAM and/or HIV infection. The specimens were collected either from induced sputum (IS), or gastric lavage (GL), or broncho-alveolar lavage (BAL), or percutaneous lung aspirates (LA). Pneumonia was defined as the radiological evidence of lobar or patchy consolidation and/or clinical evidence of severe/ very severe pneumonia according to the WHO criteria of acute respiratory infection. A total of 17 studies met our search criteria but 6 were relevant for our review. Eleven studies were excluded as those did not assess the HIV status of the children or specify the nutritional status of the children with acute pneumonia and TB. We identified only 747 under-five children from the six relevant studies that determined a tubercular aetiology of acute pneumonia in children with SAM and/or positive HIV status. Three studies were reported from South Africa and one each from the Gambia, Ethiopia, and Thailand where 610, 90, 35, and 12 children were enrolled and 64 (10%), 23 (26%), 5 (14%), and 1 (8%) children were identified with active TB respectively, with a total of 93 (12%) children with active TB. Among 610 HIV-infected children in three studies from South Africa and 137 SAM children from other studies, 64 (10%) and 29 (21%) isolates of M. tuberculosis

  20. Pulmonary tuberculosis with airspace consolidation vs mycoplasma pneumonia in adults: high-resolution CT findings

    To analyse and compare high-resolution CT findings of pulmonary tuberculosis with consolidation and mycoplasma pneumonia. Twenty patients with pulmonary tuberculosis [confirmed by sputum culture (n=9) and bronchoscopic biopsy (n=11)] and airspace consolidation on high-resolution CT and 17 patients with mycoplasma pneumonia, confirmed by serologic test, were included in this study. High-resolution CT findings were analyzed in terms of ground-glass opacities, distribution of consolidation, type of nodules, cavities, interlobular septal thickening, bronchial dilatations, bronchial wall thickening and pleural effusion. In patients with tuberculosis, average age was 33.5 years (range, 20-67); in those with mycoplasma pneumonia it was 32.5 years (range, 17-74). Segmental and subsegmental distributions were most common in both diseases; the preferred site of consolidation was different, however; for tuberculosis it was the upper lobes (13 cases, 65%; bilateral involvement, 7 cases); for mycoplasma pneumonia it was the lower lobes (11 cases, 64.7%). Non-segmental (diffuse and random) distribution of ground-glass opacities were seen in two patients(11.8%) with mycoplasma pneumonia. Centrilobular nodules, branching linear opacities and alveolar nodules were not different in both diseases, but there were nodules above 10mm in 14 cases of tuberculosis and in only one case of mycoplasma pneumonia. Tree-in-bud appearances were seen in five cases of tuberculosis. Cavities without air-fluid level were noted in ten cases of tuberculosis. Other interlobular septal thickening, bronchial wall thickening, bronchial dilatation and pleural effusion were not different in both diseases. There was considerable overlap between high resolution CT findings of tuberculosis with airspace consolidation and those of mycoplasma pneumonia. The location of consolidation, type of nodules, and the presence of tree-in-bud appearance and cavities help in the differentiation of the two diseases, however

  1. Tonsillar tuberculosis, with primary pulmonary focus: A Case Report

    Juan Antonio Lugo Machado

    2015-09-01

    Full Text Available Tuberculosis is an infectious disease that affects various organs and tissues, with greater tropism for lung disease, gastrointestinal and central nervous system tissue and even bone. However isolated cases of affection to other structures have been reported, just like this patient who came with symptoms in the tonsils and subsequently, lung involvement became apparent. The tonsillar infection in this case was considered a secondary tuberculosis with primary focus in the lungs.

  2. Computed tomographic assessment of the surgical risks associated with fibrocavernous pulmonary tuberculosis

    We evaluated the surgical risks associated with fibrocavernous pulmonary tuberculosis by retrospectively examining chest computed tomography (CT) scans. We reviewed the records of 40 patients who underwent pulmonary resection for fibrocavernous pulmonary tuberculosis, for whom preoperative CT scans were available. The disease was categorized as class I, defined as a cavity within one lobe without remarkable pleural thickness, in 21 patients; class II, defined as a cavity extending beyond one lobe or within one lobe with remarkable pleural thickness, in 10 patients; and class III, defined as bilateral cavities, in 9 patients. Four of the nine patients with bilateral cavities underwent bilateral pulmonary resection and five underwent unilateral pulmonary resection. The study parameters were intraoperative blood loss, operative time, hospital stay, major operative morbidity, and hospital death. Intraoperative blood loss and operative time were significantly greater and hospital stay was significantly longer in patients with advanced disease (P=0.046, P=0.000, and P=0.143, respectively). Major surgical morbidity mainly occurred in association with advanced disease (P=0.028) at the following incidences: class I, 5%; class II, 30%; class III, 44.4%. Two hospital deaths occurred, both following bilateral pulmonary resection for class III disease, accounting for an overall 5% mortality rate. The surgical risks associated with fibrocavernous pulmonary tuberculosis were well correlated with anatomic involvement, according to the extent of cavitation and the severity of pleural thickness, as depicted by CT. Staged pulmonary resection or the combination of one-sided resection with other modalities is recommended for the treatment of bilateral cavities. (author)

    Objective: To determine the polymorphisms of Interleukin-10 (IL-10) (-592, -1082) in pulmonary tuberculosis (PTB) with and without type 2 diabetes (T2D). Methods: We studied a Mexican mestizo population of 37 patients with TB in remission (TBr) and 40 with active pulmonary TB (PTB), 21 patients with TB + T2D, 47 blood donors accepted, and 13 healthy health-care workers with tuberculin skin test positive. Determination of IL-10 polymorphisms was performed by real-time Polymerase chain reaction. Results: IL-10-592C/A presented in a greater proportion in healthy individuals than in patients with type 2 diabetes and TB in a not quite significant statistically manner. IL-10-1082A/A presented more frequently in the group of patients with both diseases, not being statistically significant in comparison with the group of healthy subjects. Conclusions: This study describes two important new findings. First, it reveals that the IL-10 (-592 A/A and -592 C/C) polymorphisms were found in a greater proportion in a group of patients with T2D and TB than in healthy subjects. Second, the study provides evidence that the (-1082 G/G) polymorphism presented with greater frequency in healthy individuals than in patients with both of these diseases.

    AIM: Although the quality of currently available urinary tests for detecting antibody to Helicobacter pylori (H pylori)have been proved in some populations, the accuracy has not been studied regarding patients who suffer from pulmonary tuberculosis with multi-drug treatments. The present study was conducted to evaluate the accuracy of these urinary tests for antibody to H pylori in these patients.METHODS: Serum samples from 61 inpatients with pulmonary tuberculosis were tested using enzyme immunoassay, and urine samples were assayed by enzyme-linked immunosorbent assay method (URINELISA) and immunochromatography method (RAPIRAN). Medicines prescribed to the patients were recorded for medical charts, to evaluate the influences on the results of urinary tests.RESULTS: The sensitivity, specificity, and consistency of URINELISA against the serum test were 93.1%, 65.6%, and 78.6% respectively, and those of RAPIRAN were 86.2%,93.7%, and 90.1% respectively, which were almost equal to the data previously reported. Prescribed medicines had little influence on the results.CONCLUSION: The two urinary tests for detecting H pylori antibody have a diagnostic accuracy in patients with pulmonary tuberculosis given multiple anti-tuberculosis drugs.

    Full Text Available Nontuberculous mycobacteria (NTM diseases became relevant with the emergence and spread of HIV and are also related to lung infection in non-HIV individuals with structural lung diseases. Mycobacterium sherrisii is a NTM first characterized in 2004. Only a few cases have been reported. The aim of this case report is to describe the first detailed case of infection with M. sherrisii in a patient with silicosis and history of pulmonary tuberculosis. A 50-year-old HIV-negative white male, previous smoker, with silicosis and a history of treated pulmonary tuberculosis developed a worsening of cough and expectoration pattern, and two sputum samples were positive for acid-fast bacilli. Presumptive treatment for pulmonary tuberculosis was initiated with rifampin, isoniazid, pyrazinamide, and ethambutol, but, at month 5 of treatment, despite correct medication intake and slight improvement of symptoms, sputum bacilloscopy remained positive. Sputum cultures were positive Mycobacterium sherrisii. Treatment regimen was altered to streptomycin (for 2 months, ethambutol, clarithromycin, rifabutin, and trimethoprim-sulfamethoxazole. M. sherrisii should be considered a possible etiological agent of lung infections in patients with pneumoconiosis and history of tuberculosis.

    Full Text Available The aim of this study was to analyse the clinical, epidemiological and bacteriological features present in 60 pulmonary tuberculosis patients who were also infected with human immunodeficiency virus (HIV and to compare these with 120 TB patients who were not infected with HIV. The patients with pulmonary tuberculosis and HIV coinfection were mostly male (p = 0.001, showed a higher frequency of weight loss >10 kilos (p <0.001, had a higher rate of non-reaction result to the tuberculin skin test (p <0.001, a higher frequency of negative sputum smear examination for acid-fast bacilli (p = 0.001 and negative sputum culture for Mycobacterium tuberculosis (p = 0.001. Treatment failure was more common in those who were HIV positive (p <0.000. No higher frequency of resistance to antituberculosis drugs was found to be associated with TB/HIV coinfection (p = 0.407. Association between extrapulmonary and pulmonary tuberculosis was more frequent in those seropositive to HIV than those without HIV virus, 30% and 1.6% respectively. These findings showed a predominance of atypical clinical laboratory features in co-infected patients, and suggest that health care personnel should consider the possibility this diagnosis.

  9. Frequency of a typical radiological pattern of pulmonary tuberculosis in adults and elderly (dissertation based article)

    Tuberculosis is one of the oldest diseases and one third of the world's population is affected. Typical pattern (infiltration and or nodules with or without cavitations involving upper zone lung field) of pulmonary tuberculosis is the most common mode of radiological presentation in adults. There is a trend towards a relative increase in the unusual radiological presentations. This study was conducted to determine the frequency of atypical radiological trend of pulmonary tuberculosis in adults and elderly. Subjects and Methods: The objective of the study was to determine frequency of a typical radiological pattern of pulmonary tuberculosis in adults and elderly. It was a descriptive (case series) study and was conducted in the Department of Pulmonology, Nishtar Hospital Multan. The study duration was six months from 24 May 2006 to 23 November 2006. 300 patients presenting with pulmonary tuberculosis were selected. History and clinical examination was done. Relevant investigations and x-ray chest were carried out. Lesions like infiltration with or without cavitation were localized in upper, middle and lower zones. Groups of patients with their x-ray findings in different zones were made and analyzed accordingly, data collected were entered in specific proforma. Results: 205 (97.6%) adults and 85 (94.4%) elderly presented with cough while 205 (97.6%) adults and 75 (83.3%) elderly presented with fever. Out of 300 cases infiltration was found in 141 (46.19% vs 48.88%) young adult and elderly cases. There were 99 cases with nodule (35.71% vs 26.66%) and 60 cases had cavitation (18.09% vs 24.44%). Conclusion: There is a trend towards a relative increase in the frequency of unusual radiological presentations which is more common in elderly. (author)
