Características epidemiológicas y radiológicas en un grupo de pacientes con neumonía tuberculosa sin inmunodepresión o comorbilidades / Epidemiological and Radiological Characteristics of a Group of Patients with Tuberculous Pneumonia without Immunosuppression or Comorbidities

La neumonía tuberculosa es una patología poco frecuente, descripta mayormente en pacientes con inmunosupresión o comorbilidades, como alcoholismo o diabetes, con una presentación radiológica similar a la neumonía bacteriana, lo cual puede dar lugar a retrasos en el diagnóstico. En este trabajo, se incluyeron pacientes con diagnóstico de tuberculosis e imagen radiológica de consolidación en los campos pulmonares inferiores y sin comorbilidades asociadas. En el transcurso de tres años identificamos veinticinco pacientes con estos criterios entre 628 casos de tuberculosis pulmonar evaluados. No encontramos relación con el sexo, y resulta más frecuente la afectación del lóbulo inferior derecho (84%) que el izquierdo.

Tuberculous pneumonia is a rare disease, mostly described in patients with immunosup pression or comorbidities such as alcoholism or diabetes, with a radiological presentation similar to bacterial pneumonia, which can lead to delays in diagnosis. Patients with a diagnosis of tuberculosis and radiological image of consolidation in the lower lung fields and without associated comorbidities were included in this study. Over the course of 3 years, we identified 25 patients with these criteria among 628 cases of pulmonary tuberculosis evaluated. We found no relationship with sex, with the right lower lobe be ing affected more frequently (84%) than the left.

Contexte + objectif : les signes cliniques et paracliniques en particulier radiologique ne sont pas spécifi ques d'un processus infectieux. L'objectif de cette étude était de déterminer les micro-organismes non tuberculeux en cause au cours des infections respiratoires dans le service de Néphrologie du CHU du Point G. Méthode : il s'agissait d'une étude prospective et descriptive allant du 1er janvier 2018 au 30 juin 2019, soit 18 mois. Etaient inclus, tous les patients en insuffi sance rénale chronique (IRC) souffrant d'une pneumopathie infectieuse diagnostiquée cliniquement, radiologiquement et/ou bactériologiquement. Résultats : Nous avons colligés 35 patients, 21 hommes et 14 femmes. L'âge moyen a été de 46,8 ± 13,9 ans avec des extrêmes de 23 et 76 ans. Les patients âgés de plus de 45 ans étaient majoritaires (54,3%). L'IRC était terminale chez tous nos patients avec un débit de fi ltration glomérulaire moyen de 6,7 ml/min/1,73m2. La radiographie thoracique de face a révélé une pneumopathie alvéolaire (65,7%), une pleuropneumopathie (28,6%) et une pneumopathie cavitaire (5,7%). Les bactéries non tuberculeuses retrouvées à l'examen cytobactériologique des crachats étaient : Klebsiella pneumoniae (25,7%), Escherichia coli (11,4%), Citrobacter frendii, Pseudomonas aeroginosa, Staphylococcus aureus, Candida albicans soit 5,7% pour chacune, Enterobacter clocae et Enterococcus sp avec 2,9% chacune. Quatre (11,4%) sur 35 présentaient une tuberculose dont 1 cas (2,9%) de coïnfection de germe banal. Conclusion: Le diagnostic de la tuberculose par bacilloscopie entraine des cas de méconnaissance des germes banals associés.

Context and objective. Clinical and paraclinical signs, in particular radiological signs, are not specifi c to an infectious process. The objective of this study was to determine the non-tuberculous microorganisms involved in respiratory infections in the Nephrology department of the CHU du Point G. Methods. This was a prospective and descriptive study from January 1, 2018 to June 30, 2019, (18 months). Included were all patients with chronic renal failure (CKD) suffering from an infectious pneumonia diagnosed clinically, radiologically and / or bacteriologically. Results. We collected 35 patients, 21 men and 14 women. The mean age was 46.8 ± 13.9 years with extremes of 23 and 76 years. The majority of patients over the age of 45 were 54.3%. IRC was terminal in all of our patients with an average glomerular filtration rate of 6.7 ml / min / 1.73m2. The chest chest X-ray revealed alveolar pneumonitis (65.7%), pleuropneumopathy (28.6%) and cavitary pneumonitis (5.7%). The non-tuberculous bacteria found on cytobacteriological examination of sputum were: Klebsiella pneumoniae (25.7%), Escherichia coli (11.4%), Citrobacter frendii, Pseudomonas aeroginosa, Staphylococcus aureus, Candida albicans, or 5.7% for each , Enterobacter clocae and Enterococcus sp with 2.9% each. Four (11.4%) out of 35 presented with tuberculosis, including 1 case (2.9%) of common coinfection. Conclusion. The diagnosis of tuberculosis by bacilloscopy leads to cases of ignorance of the associated banal germs.

Pneumonia tuberculosa: relato de caso / Tuberculous pneumonia: case report / Neumonía tuberculosa: reporte de caso

A tuberculose é uma doença infecciosa causada pelo Mycobacterium tuberculosis muito disseminada no Brasil. Tem preferência pelo acometimento pulmonar, embora vários outros órgãos possam ser afetados, como vasos linfáticos, trato geniturinário, ossos, articulações, sistema nervoso central, trato gastrointestinal e pericárdio. A pneumonia tuberculosa é uma forma rara, que se apresenta com consolidação alveolar, principalmente em lobo superior, podendo mimetizar um quadro de pneumonia pneumocócica. O objetivo deste ensaio é relatar o caso clínico de um indivíduo do sexo masculino com diagnóstico de pneumonia tuberculosa no Hospital Geral Roberto Santos (HGRS) e fazer uma breve revisão da literatura sobre o tema. O método utilizado para isso será o relato de caso clínico, com informações obtidas por meio de revisão de dados contidos em prontuário médico. Os resultados obtidos foram: paciente do sexo masculino, 19 anos, previamente hígido, não tabagista, natural de Recife, procedente de Salvador, admitido em agosto de 2019 no serviço de emergência do HGRS, com história de tosse produtiva de secreção amarelada, febre não mensurada e calafrios. O relato de caso descrito mostra uma apresentação atípica, rara e pouco comum de pneumonia tuberculosa/tuberculose pulmonar. A procura por diagnósticos diferenciais em quadros com resposta ruim à terapêutica inicialmente instituída é fundamental para evitar atrasos entre a realização do diagnóstico correto e a introdução das devidas medidas terapêuticas.

Tuberculosis is a highly prevalent infectious disease in Brazil, caused by Mycobacterium tuberculosis. Despite mostly affecting the lungs, it may also affect other organs, such as lymphatic vessels, genitourinary tract, bones, joints, central nervous system, gastrointestinal tract, and pericardium. A rare form of the disease, tuberculous pneumonia presents with alveolar consolidation, especially in the upper lobe, possibly mimicking pneumococcal pneumonia. This study sought to report the clinical case of a male individual diagnosed with Tuberculous Pneumonia at the Hospital Geral Roberto Santos, as well as to perform a brief literature review of subject. The study was conducted with data collected from the medical records of a male patient aged 19 years old, previously healthy, non-smoker, born in Recife and living in Salvador, admitted in August 2019 to the emergency service of Hospital Geral Roberto Santos with a history of productive cough yellowish sputum, unmeasured fever, and chills. The case report here described shows an atypical, rare, and uncommon presentation of Tuberculous Pneumonia/Pulmonary Tuberculosis. To avoid delays between the correct diagnosis and the introduction of the respective therapeutic measures, health professionals should search for differential diagnoses in conditions with poor response to the initially instituted therapy.

Pneumonia caused by Mycobacterium tuberculosis.

Tuberculosis (TB) is one of the top ten leading causes of death worldwide. The causative agent of TB is Mycobacterium tuberculosis. Acute tuberculous pneumonia (TP) is an acute form of pulmonary TB. However, acute TP and non-tuberculous community-acquired pneumonia can be easily confused, resulting in deterioration of TP due to delayed treatment. Therefore, rapid and accurate diagnosis of acute TP is crucial in order to stop the transmission of TB. Moreover, development of new diagnostic tools (technologies and approaches), and flexible application of different therapy schemes will help to reduce the incidence of TP and promote the goal of ending the TB epidemic.

Tuberculous pneumonia-induced severe ARDS complicated with DIC in a female child: a case of successful treatment.

BACKGROUND: Tuberculous (TB) pneumonia can induce acute respiratory distress syndrome (ARDS). Although TB pneumonia is one of the causes of disease and death among children worldwide, the literature on TB pneumonia-induced ARDS is limited. We report herein on the successful treatment of a two-year-old female child with TB pneumonia-induced severe ARDS complicated with disseminated intravascular coagulation (DIC). CASE PRESENTATION: A two-year-old Vietnamese female child with sustained fever and cough for 20 days was transferred to our hospital. She had severe dyspnea and a chest X-ray showed bilateral infiltration without findings of heart failure. After tracheal intubation, her oxygenation index (OI) and PaO2/FiO2 (PF) ratio were 29 and 60 mmHg, respectively. Mycobacterium tuberculosis was detected by real-time polymerase chain reaction (rPCR) assay of tracheal lavage fluid. She was diagnosed as having severe ARDS that developed from TB pneumonia. Anti-tuberculous therapy and cardiopulmonary support were started. However, her respiratory condition deteriorated despite treatment with high-frequency oscillating ventilation (HFO), vasopressor support, and 1 g/kg of immunoglobulin. On the third day after admission, her International Society on Thrombosis and Hemostasis DIC score had increased to 5. Recombinant human soluble thrombomodulin (rTM) was administered to treat the DIC. After the administration of rTM was completed, OI gradually decreased, after which the mechanical ventilation mode was changed from HFO to synchronized intermittent mandatory ventilation. The DIC score also gradually decreased. Plasma levels of soluble receptor for advanced glycan end products (sRAGE) and high mobility group box 1 (HMGB-1), which are reported to be associated with ARDS severity, also decreased. In addition, inflammatory biomarkers, including interferon-gamma (IFN-γ) and interleukin-6 (IL-6), decreased after the administration of rTM. Although severe ARDS (P/F ratio ≦ 100 mmHg) continued for 19 days, the patient's OI and P/F ratio improved gradually, and she was extubated on the 27th day after admission. The severe ARDS with DIC was successfully treated, and she was discharged from hospital on day 33 post-admission. CONCLUSIONS: We successfully treated a female child suffering from TB pneumonia-induced severe ARDS complicated with DIC using multimodal interventions. (338/350).

Disseminated tuberculosis with acute respiratory distress syndrome lacking granuloma formation in the lung.

A 66-year-old woman, who had been treated with systemic corticosteroids for four months for vasculitis of unknown etiology, was referred to our department due to a fever, dyspnea and patchy ground-glass opacities on chest computed tomography. As transbronchial biopsy specimens were suggestive of interstitial pneumonia, the prescribed dose of corticosteroids was increased. However, the patient developed pyrexia and presented diffuse ground-glass attenuation in the lungs bilaterally. Antituberculous drugs were administered because a previous blood interferon-gamma release assay was positive, however, the patient died of severe respiratory failure within several days, and cultures of her blood, urine and bone marrow posthumously revealed Mycobacterium tuberculosis. An autopsy revealed multiple foci of air-space pneumonia containing numerous acid-fast bacilli without granuloma formation, accompanied by diffuse alveolar damage. An immunosuppressive condition might inhibit air-space pneumonia to become granulomatous inflammation as an initial stage of pulmonary tuberculosis.

Caracterización clinicoepidemiológica de adolescentes con el síndrome de inmunodeficiencia adquirida en aldeas de Guinea Ecuatorial / Clinical and epidemiological characterization of adolescents with acquired immunodeficiency syndrome in small villages in Equatorial Guinea

Se realizó un estudio descriptivo, longitudinal y prospectivo de 480 adolescentes con el síndrome de inmunodeficiencia adquirida, pertenecientes a 2 aldeas de Guinea Ecuatorial, atendidos en un puesto de salud desde julio de 2005 hasta enero de 2007, a fin de caracterizarles según variables clínicas y epidemiológicas. Entre los principales resultados sobresalieron: las edades de 15 a 17 años, el sexo femenino y los adolescentes en estadios III y IV de la infección. La candidiasis bucal, las neumonías bacterianas y la neumonía por Pneumocystis carinii constituyeron las afecciones asociadas más frecuentes, las 2 últimas de las cuales, además de la neumonía tuberculosa, devinieron las principales causas de muerte

A descriptive, longitudinal and prospective study was carried out in 480 adolescents with acquired immunodeficiency syndrome, belonging to two small villages in Equatorial Guinea, attended in a health post from July 2005 to January 2007, in order to characterize them according to clinical and epidemiological variables. Among the main results were ages between 15 and 17 years, female sex and adolescents in III and IV stages of infection. Oral candidiasis, bacterial pneumonias and pneumonia by Pneumocystis carinii were the most frequent associated conditions, the two latter, besides tuberculous pneumonia, were the main causes of death

Clinical Investigation of Tuberculous Pneumonia / 결핵및호흡기질환

BACKGROUND: It is difficult to differentiate between tuberculous pneumonia and Community Acquired Pneumonia, so the diagnosis and treatment of tuberculous pneumonia can be delayed frequently. In this study, we attempted to retrospectively evaluate the clinical and radiologic characteristics of tuberculous pneumonia. METHODS: We conducted a retrospective analysis of clinical characteristics of 58 patients diagnosed with tuberculous pneumonia from Nov. 1997 to May 2001 at Korea university kuro hospital. RESULT: The male to female ratio was 1:1 and the mean age at diagnosis was 54.5+/-18.6 years. Fifty five patients were confirmed microbiologically and three patients pathologically. There were 20 patients(34.5%) who had diabetes mellitus(8cases), chronic obstructive pulmonary disease(3cases), malignancy(3cases), bronchiectasis(2cases), chronic renal failure(1cases) or long term history of corticosteroid treatment(3cases). Many patients had multilobar infiltration in chest X-ray, dominantly in the lower lobe. thirty two patients(55.2%) had infiltration in more than 2 lobes and 5 patients in more than 4 lobes. The significant correlation between the diabetes mellitus and the infiltrated Rt lower lobe(RLL) was found on the borders of confidence limit.(P=0.07<0.1). There was significant correlation between woman and infiltrated lobe(RML, RLL, LLL) excluding the both upper lobe(P=0.029). CONCLUSION: We must consider tuberculous pneumonia when lobar pneumonia with consolidation resistant to antibiotics, especially in the patients who have diabetes mellitus, chronic obstructive pulmonary disease, malignancy, bronchiectsis, chronic renal failure or long term history of corticosteroid treatment.

A Case of Tuberculous Pneumonia in Infancy

A rare but serious complication of tuberculosis in a child occurs when the primary infection is progressively destructive. It is difiicult to differentiate from other bacterial pneumonias. We experienced a case of tuberculous pneumonia in a 73-days-old male who presented with cough, fever and progressive dyspnea. Chest X-ray shows diffuse pneumonic consolidation on right upper lung field, Mantoux test was positive and his father was diagnosed with active pulmonary tuberculosis 2 months ago. We started antituberculous drugs: INH, RFP, PZA, SM and prednisolone. At 12 weeks after therapy, chest CT and percutaneous aspiration lung biopsy was performed due to worsening of X-ray findings. The diagnosis of tuberculous pneumonia was confirmed. He was treated with INH, RFP, PZA for 52 weeks. Short-term corticosteroid therapy and SM or KM was also used. The pneumonic consolidation was totally cleared and healed with fibrosis.

Clinical significance of CA125 level in tuberculous pneumonia / 결핵

BACKGROUND: In case of tuberculous pneumonia, differentiation from bacterial lobar pneumonia is sometimes very difficult because clinical symptoms, signs and radiological images are very similar. So we investigated the usefulness of CA125, which is known to increase in tuberculous diseases, in differential diagnosis between tuberculous pneumonia (TBPN) and community acquired bacterial lobar pneumonia (LP). METHODS: Serum CA125 level was measured in 20 patients with TBPN (female 12 male 8: mean age 36.1 years) and 14 patients with LP (female 5 male 9: mean age 45.1 years) by radioimmunoassay (Centocor(R) CA125 RIA kit). RESULTS: 1) The serum CA125 level in TBPN (333.7 283.5 u/ml) was higher than in LP (60.9 66.2 u/ml). (P 0.05) 4) Following up of serum CA125 level after initiation of antituberculosis treatment showed rapid decline and approach to near normal range in 6 months. CONCLUSION: High serum CA125 level (> 195 u/ml) was useful in differential diagnosis of TBPN from LP.
