Accidental Detection of Tuberculous Empyema at Health Check-Up.

BACKGROUND: Patients with tuberculous empyema (TE) can have a serious impact on lung function as their disease progresses, and, if left untreated, can cause damage to other parts of the body such as the thorax and spine, causing pain and inconvenience to the patient. Early diagnosis and the search for appropriate treatment are key to improving the survival rate of the disease. METHODS: We report a case of a young patient with an unexpected finding of right pleural effusion on physical examination, who was eventually diagnosed with TE using next-generation sequencing of pleural tissue. We analyzed the literature to improve clinicians' understanding of TE and how to properly diagnose and treat the disease. RESULTS: Laboratory results of the pleural effusion suggested a possible Mycobacterium tuberculosis infection, but pathogen-related tests were negative, and the diagnosis was eventually successfully confirmed by thoracoscopic pleural biopsy. CONCLUSIONS: The diagnosis of TE should be considered in young patients with pleural thickening of the empyema. Adenosine deaminase may provide diagnostic direction in patients with unexplained thorax abscess. Pleural biopsy, although an invasive procedure, is an essential diagnostic tool in some cases.

Risk factors associated with postoperative respiratory failure in tuberculous empyema patients.

ABSTRACT: Our objective was to identify independent risk factors for predicting which patients in the Chinese population would likely develop respiratory failure.A descriptive analysis was conducted of demographic and clinical data of patients with tuberculous empyema (TE) admitted to the Beijing Chest Hospital, Capital Medical University between January 2001 and January 2020. Risk factors associated with postsurgical respiratory failure in TE patients were identified based on results of analyses based on univariable and multivariable logistic regression models.A total of 139 TE patients who underwent surgical treatment in the Beijing Chest Hospital, Capital Medical University from January 2001 to January 2020 were enrolled in this study. Cases included 109 male and 30 female patients, with an overall mean age (range 17-73) of 39.3 years. Of 139 TE patients, 26 (18.7%) experienced respiratory failure after surgery. Among significant risk factors for postsurgical respiratory failure, intraoperative blood loss volume greater than 1000 mL had the highest odds ratio value of 6.452. In addition, a pathologic preoperative pulmonary function test result showing a high partial pressure of carbon dioxide level was an independent risk factor for respiratory failure. Moreover, the presence of tuberculosis lesions in the contralateral lung was another significant risk factor for respiratory failure, as determined using multivariate analysis.Respiratory failure is a predominant complication experienced by TE patients undergoing surgery. High intraoperative blood loss, high preoperative high partial pressure of carbon dioxide level, and tuberculosis lesion(s) in the contralateral lung of TE patients were associated with increased risk of postoperative respiratory failure.

Mixing It Up: Coadministration of tPA/DNase in Complicated Parapneumonic Pleural Effusions and Empyema.

BACKGROUND: A recent randomized controlled trial showed 12 serial doses of tissue plasminogen activator (tPA) and deoxyribonuclease (DNase) is safe and effective in managing complicated parapneumonic pleural effusions and empyema (CPEE). However, this regimen is laborious, requiring trained personnel to open/close the chest tube 8 times daily for 3 days. We present our observational data using a simplified regimen of coadministered tPA/DNase. MATERIALS AND METHODS: This is a retrospective observational study of patients who received coadministered tPA/DNase for CPEE from January 2012 to April 2015 at the University of Texas Medical Branch. Patient demographics, pleural fluid, radiologic and treatment characteristics, and outcomes were collected. Data are presented as proportions and percentages. Our primary outcome was successful treatment without need of surgery and discharge home alive. Secondary outcomes were dose and length of treatment and hospital stay, treatment complications, and 90-day mortality. RESULTS: The study included 39 patients. All pleural effusions were loculated, 59% macroscopically purulent, 50% had a positive organism in Gram stain, and 40% were culture positive. A median of 6 (interquartile range, 3.5 to 6) doses were coadministered mainly via small bore chest tube (≤14 Fr in 79%) with a median of 14.5 (interquartile range, 9.5 to 21.5) hospital days. Overall, 85% were successfully treated without need for surgery. Treatment failures occurred in 15%: 3/39 (7%) received surgery; 3/39 (7%) died. Only 1 (2.5%) complication of hemorrhagic pleural effusion resolved after discontinuation of intrapleural treatment. CONCLUSIONS: Our study shows intrapleural coadministration of tPA/DNase was effective and safe in management of CPEE.

Unusual cause of chest pain: empyema necessitans and tubercular osteomyelitis of the rib in an immunocompetent man.

A 33-year-old man, born in India but resident in the UK for 5 years, presented to the emergency department with a 4-week history of a dry cough and right-sided pleuritic chest pain. He reported systemic features, including fever and unintentional weight loss. His medical history included vitamin D deficiency. He had travelled to India 10 months previously and denied any exposure to tuberculosis (TB). He was an ex-smoker with a 20 pack history. Respiratory examination confirmed decreased air entry of the right lower lobe and stony dullness on percussion. His C reactive protein was 178 mg/L. A chest radiograph identified a moderate-sized right-sided pleural effusion and destruction of the lateral aspect of the right fifth rib, strongly suggestive of underlying malignancy. Further investigation with a CT of the thorax identified a focal lytic lesion in the right fifth rib, at its lateral aspect, with expansion of the rib observed. Ultrasound-guided pleural aspiration confirmed an exudative pleural effusion. Gram stain revealed no organisms or polymorphs. Four days post admission, the patient was transferred to the regional thoracic surgery unit and underwent video-assisted thoracic surgery, bronchoscopy and drainage of his empyema. His Mantoux tuberculin skin test and his TB Elispot were negative, suggesting that TB infection was unlikely. Culture confirmed no growth after 48 h incubation. Histology of his pleural biopsy identified multiple non-confluent necrotising granulomatous inflammation with very occasional acid-alcohol-fast bacilli-like organisms, highly suspicious for mycobacterial infection. The isolate, Mycobacterium tuberculosis, was identified by Accuprobe and HAIN tests, respectively. MPT64 erythrocyte sedimentation rate (ESR) results from the fifth rib were positive for M. tuberculosis. This case report discusses the aetiology, clinical presentation and pathophysiology of both empyema necessitans and tubercular osteomyelitis of the rib.

Effect of decortication and pleurectomy in chronic empyema patients.

BACKGROUND: Fibrosis that occurs in the chronic phase of pleural empyema restricts lung movement and impairs pulmonary function. It also leads to asymmetry of the chest wall. We evaluated the efficacy of decortication and pleurectomy in improving these adverse consequences. METHODS: Data of 50 patients (42 males, mean age 49.1 ± 19.46 years) with chronic empyema who underwent lung decortication via a posterolateral thoracotomy between 2004 and 2014 were reviewed in this study. All patients had pulmonary function tests before and after surgery. Computed tomography was used to determine transverse and anteroposterior diameters of the chest before and after surgery. RESULTS: The patients were followed up for 11.5 ± 4.5 months. Mean forced expiratory volume in 1 s was 62.5% ± 13.61% before surgery vs. 77.3% ± 13.31% after surgery (p < 0.001). Mean forced vital capacity was 60.6% ± 14.38% before surgery vs. 78.5% ± 12.64% after surgery (p < 0.001). The improvement in patients with reduced chest wall diameters was significant (p < 0.001). Improvements in pulmonary function tests and chest wall diameters were not significantly different between patients with tuberculosis (n = 10) and those with other diseases (n = 40; p < 0.05). CONCLUSION: Decortication and pleurectomy via a posterolateral thoracotomy significantly improves pulmonary function and chest wall diameters in patients with chronic empyema due to tuberculosis or other diseases.

Therapeutic drug monitoring and the conservative management of chronic tuberculous empyema: case report and review of the literature.

BACKGROUND: Chronic tuberculous empyema (CTE) is a rare and unusual, low grade and protracted, infection of the pleural space resulting in marked thickening, even calcification of the visceral and parietal pleura. Historically its management has been extraordinarily challenging. Differential penetration of anti-TB drugs into the pleural space has resulted in acquired drug resistance and surgery to remove the empyema or close a complicating bronchopleural fistula (BPF) has been technically difficult or unacceptably hazardous. On the basis of limited experience, the combination of tube thoracostomy or catheter drainage and high-end dosing of anti-TB drugs has been recommended as an initial approach to these lesions. Herein we report the first well documented case of closure of a BPF and cure of a CTE using this approach. The chances of a favorable outcome are improved, we suggest, by using therapeutic drug monitoring (TDM) to guide high-end drug dosing. CASE PRESENTATION: An 84 year old male immigrant to Canada from Croatia was diagnosed with a CTE after he developed a BPF. The diagnosis was made 62 years after what was, in retrospect, an episode of tuberculous pleurisy. He was treated with computed tomography-guided catheter drainage and TDM-guided high-end dosed anti-TB drugs (serum and pleural fluid drug concentrations) over a 10 month period. Sustained closure of the BPF and mycobacteriologic cure of the CTE was achieved. Drug concentrations in the present case and all other reported cases are summarized and interpreted. CONCLUSION: When serum concentrations of the anti-TB drugs isoniazid, pyrazinamide and ethambutol at the high end of the normal range are achieved, pleural fluid concentrations at the low end of the normal range may be anticipated in CTE. Though highly protein bound drugs such as rifampin and moxifloxacin appear to penetrate CTEs less well, their free concentrations in the pleural space may be proportionately higher on account of lower protein concentrations. Interventional radiology and TDM increase the chances that conservative management of CTE will be successful.

Outcomes of Video-Assisted Thoracic Surgical Decortication in 274 Patients with Tuberculous Empyema.

OBJECTIVE: The present work aimed to retrospectively assess the outcomes associated with decortication by video-assisted thoracic surgery (VATS) in patients with tuberculous empyema. METHODS: Patients (n = 274) who underwent decortication by VATS for surgical management of pleural empyema between January 2000 to 2010 were included. Pre-, intra-, and postoperative characteristics were observed for all patients, which were followed up for 12 months to evaluate surgical outcomes such as postoperative complications and disease recurrence. RESULTS: No patients required conversion to thoracotomy, and no death or postoperative bleeding was reported. The mean operation time was 104.5 ± 20.4 min, with 271.5 ± 41.3 ml intraoperative blood loss and median length of hospital stay of 7.2 ± 3 .4 days. Of the 274 patients, 262 were followed up for 12 months; 26 (9.9%) patients showed complications, including incomplete lung re-expansion (11 patients) and persistent air leak (6 patients). While early disease recurrence was observed in 3 (1.1%) patients after surgery, late recurrence was reported for 6 (2.3%) individuals. Interestingly, the complication rate was much higher in patients with chronic empyema (15/34, 44.1%) than in subjects with acute empyema (11/228, 4.8%). CONCLUSIONS: Decortication by VATS decreases postsurgical complications, and results in decreased disease recurrence. This study demonstrated improved outcomes by decortication by VATS, even in patients with stage III tuberculous empyema.

Evaluation of extra pulmonary tuberculosis in Bangladeshi patients.

This is a retrospective study of 200 cases of Extra Pulmonary Tuberculosis (EPTB) and this study was conducted from January 2010 to July 2011 at Sheheed Ziaur Rahman Medical College Hospital and TB clinic, Bogra, Bangladesh. Data were collected from the Hospital records on demographics, clinical, laboratory and treatment out come status. The incidence of EPTB was high in 16-45 years age group (55%), mean age was 35.67±14.6 years and predominated in Female patients (60%). Extra pulmonary Tuberculosis (EPTB) still constitutes an important clinical problem in Bangladesh. The objective of this study was to evaluate the demography and features of patients with EPTB in our high burden tuberculosis country. Lymph nodes are the most common site of involvement (50%) followed by tubercular pleural effusion (15%) and virtually every site of the body can be affected by tuberculosis. Since the clinical presentation of EPTB is atypical, tissue samples for the confirmation of diagnosis can sometimes be difficult procedure and conventional diagnostic method have a poor yield, so the diagnosis is often delayed. EPTB constitutes about 15-20% of all cases of TB patients and it is more common in low socio-economic group (60%) Biopsy and/ or surgery, FNAC is required to procure tissue samples and pus and/or aspirated fluids are required for diagnosis and for managing complications. The EPTB usually responds to standard anti tubercular drug regimen.

[Tuberculous spondylitis of vertebra with fracture, paraparesis and pleural empyema complications--case report].

INTRODUCTION: Spine tuberculosis is caused by Micobacterium tuberculosis. It is localized in the vertebral body or intervertebral disc. Its diagnosis is often delayed because of nonspecific symptoms and neglected presence of tuberculosis, which leads to serious complications. CASE REPORT: This paper presents a case of tuberculous spondylitis, which was complicated with the fracture of vertebra, paraparesis of lower extremities and pleural empyema. The treatment with antituberculous drugs started after the fracture of 10th and 11th thoracic vertebras. The therapy brought some improvement but paraparesis of lower extremities remained. In the further course of disease, inflammatory process affected the pleura. Antibiotic and antitubercular therapy with puncture of pleura were not very effective. Operation was performed on December 20th 2011: Thoracotomia lat. dex. Decorticatio pulmonum lat.dex. Seven months after surgery, the patient was without symptoms. CONCLUSION: Tuberculous spondylitis occurs relatively frequently in clinical practice. Early diagnosis and adequate therapy of this disease can prevent the occurrence of its serious complications.

[Video-assisted thoracoscopy in the diagnosis and surgical treatment of tuberculosis and other respiratory diseases].

Resection operations performed on the lung using endoscopic techniques are divided into VATS and video-assisted thoracoscopy. Our experience with VATS in patients with pulmonary tuberculosis and other respiratory disorders is 66 transactions. Complications in the postoperative period were not observed. The advantages of VATS in phtiziosurgical practice are high information content, reducing the time of diagnosis; reduction in the number of patients receiving test treatment, improve treatment quality and outcome of disease through early diagnosis verification, reducing economic losses due to refusal of the trial unreasonably prolonged courses of therapy for tuberculosis in the absence of radiographic dynamics.

Spontaneous haemoptysis as a late complication of plombage in a tuberculosis patient.

The endemic spread of tuberculosis after World War II and the deficiency of appropriate antituberculous drugs had led to a renaissance of the surgical tuberculosis therapy until the early 1950s. Late complications of plombage performed decades before are rare and are mainly related to infection and/or migration of the inserted foreign material and are scarcely recognized today. We report on a 73-year-old male patient, who was admitted to the emergency room of our hospital with acute massive haemoptysis for four days. On physical examination the patient presented with decreased breath sounds over the left lung and an old left-sided thoracotomy scar. Radiological findings and bronchoscopy revealed an empyema and a fistula as late complications 53 years after collapse therapy with insertion of a plombage for the treatment of pulmonary tuberculosis. The endobronchial nylon threads in the left bronchial tree and the fistula ending in the left lower bronchus confirmed our diagnosis. The patient was successfully treated by resection of the affected lower lobe. The present casuistic demonstrates a rare cause of spontaneous haemoptysis: late complications after extrapleural pneumolysis and plombage for cavitary tuberculosis over 50 years after the initial operation.

Derrame pleural: [revisión] / Pleural effusion: [review]

El derrame pleural se define como la acumulación anormal de líquido en el espacio pleural; no es una enfermedad, es el resultado del desequilibrio entre la formación y la reabsorción del líquido como manifestación de alguna condición que incluso puede amenazar la vida del paciente. Es una entidad a la cual el clínico se ve enfrentado con frecuencia, la mayoría de las veces es secundaria a enfermedad pleural o pulmonar, pero puede también ser causada por enfermedades extrapulmonares, sistémicas o neoplásicas (bien sea primarias o metastásicas)...

[Pleural effusions--experience of Pneumo-phtisiology Hospital Tudor Vladimirescu--I: Clinical study]. / Pleureziile--experienta Spitalului de Pneumoftiziologie Tudor Vladimirescu I: studiul clinic.

Pleural effusions still represent major problem of respiratory tract pathology because of the invalidity potential of pleural involvement and because of the increasing incidence of diseases frequently accompanied by pleural effusion such as tuberculosis and malignant pleural proliferations. The retrospective study concerned 221 cases with pleural effusions divided into three groups depending on the etiology (bacillary, neoplastic and others). Two categories of features were assessed: parameters assessed in the first 48 hours (epidemiological data, history data, clinical data, IDR and sedimentation rate) and parameters assessed after thoracentesis and/or pleural biopsy (LDH in pleural fluid and BK presence in pleural fluid and biopsy specimens). Bacillary etiology was dominating the studied group but possibly because the hospital was well known as a mainly antituberculous medical unit. The main profile of the investigated patients was: man, teenaged or adult, smoker and often alcoholic living in town. Clinical appearance was influenced by the triad: etiologic agent, age, amount of pleural fluid. Reduced amount of pleural fluid was related to acute onset, usually in young men and symptomatology dominated by thoracic pain. In contrast, massive pleural effusion was related with chronic onset, dyspnea and adult or old age. LDH and glyco-pleuria values are not pathognomic but useful for diagnostic orientation but if microscopic or culture evidence of BK in pleural fluid or tissue specimens are added, the diagnostic accuracy is increasing. In conclusion, a thorough clinical examination completed with a complex panel of laboratory investigations, including biochemical microbiological and special tests from pleural fluid and also a cytological examination could guide the diagnostic in establishing the type and the cause of pleural effusion.

Primary cutaneous inoculation tuberculosis in a healthcare worker as a result of a surgical accident.

In May 2004, a 48-year-old male surgeon, resident in Bucaramanga, Colombia, suffered a superficial cut with a scalpel to the lateral aspect of the mid-phalanx of the second finger of the left hand while performing a pulmonary decortication surgical procedure for tuberculous empyema with pulmonary entrapment. The injury healed normally but, approximately 2 weeks after the event, an erythematous, nonpainful papule of approximately 3 mm in diameter developed, and increased progressively to 7 mm 3 days after its initial appearance. At this time, the papule showed spontaneous secretion of a clear liquid and superficial ulceration (Fig. 1). Approximately 3 weeks after the injury, a Gram stain of the liquid was performed; it showed no bacteria but a moderate leukocyte reaction. Because of the high suspicion of possible tuberculous infection, bacilloscopy of the liquid was performed, and was positive (++) for acid-fast bacteria (Fig. 2). The liquid was cultured and grew Mycobacterium tuberculosis. The culture was sent to the Laboratory of Mycobacteria at the National Institute of Health, Bogota, Colombia for drug resistance testing. Susceptibility was demonstrated against streptomycin, isoniazid, rifampicin, and ethambutol. During this time, the patient presented an ipsilateral painful axillary adenopathy of about 2.5 cm in diameter. The patient consulted with an infectologist, who initiated a Directly Observed Therapy Short Course (DOTS) regimen [first phase (8 weeks): daily, except Sundays, streptomycin 1 g intramuscularly, pyrazinamide 1500 mg orally, isoniazid 300 mg, and rifampicin 600 mg; second phase (18 weeks): twice weekly rifampicin 600 mg and isoniazid 500 mg], accompanied by daily pyridoxine to prevent secondary effects from isoniazid. After 3 weeks of treatment, the finger lesion had disappeared. Treatment was undertaken as described above, with the patient reporting symptoms of vertigo, nausea, epigastralgia, and mild myalgia as the adverse effects of medication. A chest x-ray was taken and reported to be normal. The axillary adenopathy disappeared approximately 6 months after the injury. Nearly 3.5 years after the incident, the patient has not presented any type of symptomatology.

Tuberculous empyema necessitatis. A rare cause of cutaneous abscess in the XXI century.

A 24-year-old Moroccan man was admitted to the hospital because of a tumor of the abdominal wall, fever, and purulent sputum. Imaging tests showed the presence of a pleural effusion and tumor in the right abdominal wall. The organized collection of liquid in the mass was contiguous with the thoracic collection and that of the subphrenic space. Thoracocentesis removed purulent material suggestive of empyema. Cultures and polymerase chain reaction (PCR) tests confirmed the diagnosis of tuberculous empyema. Empyema necessitatis refers to empyema that extends into the extrapleural space through a defect in the pleural surface. Various infectious etiologies may be responsible. Tuberculous empyema necessitatis is a rare complication of tuberculosis (TB); our case is even more unusual because this condition presented as an abdominal wall abcess and the patient was immunocompetent. His only predisposing factors were his country of origin, where there is a high prevalence of TB and the delay in diagnosis due to a lack of access to health care.

Tuberculose pleural / Tuberculous pleural effusions

O derrame pleural tuberculoso pode ser devido a uma manifestação da forma primária da doença ou da reativação de uma infecção latente pelo M. tuberculosis. Os avanços nos métodos laboratoriais contribuíram sobremaneira para um melhor diagnóstico e para a compreensão da fisiopatologia desta doença. No entanto, embora o derrame pleural predominante linfocítico seja indicativo de tuberculose em nosso meio, uma rotina de abordagem diagnóstica deve ser instituída a fim de orientar o tratamento precoce e evitar seqüelas.

Tuberculous pleural effusion is a common manifestation of the primary form of the disease or consequence of the reactivation of a latent infection due to the M. tuberculosis. Advances in the laboratory methods have contributed to better diagnose and understand the pathophysiology of the effusion secondary to tuberculosis. However, although a predominant lymphocytic pleural effusion is suspicious of tuberculosis, a diagnostic routine shall be instituted to orient treatment and prevent undesirable sequels.
