ABSTRACT

OBJECTIVES: Tuberculosis is one of the most prevalent infections in humans. Although culture is the reference for diagnosis, its sensitivity is compromised, especially in paucibacillary samples. Because polymerase chain reaction (PCR) amplifies mycobacterial DNA, it is more sensitive than culture for the diagnosis of Mycobacterium tuberculosis (Mtb). However, its performance can be affected by intrinsic sample inhibitors and by the extraction/detection techniques used. METHODS: We evaluated the influence of preanalytical conditions on Mtb detection in samples of sputum (SPU), bronchoalveolar lavage (BAL), and pleural fluid (PF) using combinations of extraction/detection methods. Respiratory samples were prepared to contain different concentrations of red blood cells and nucleated cells to which increasing amounts of Mtb colonies were inoculated and submitted to PCR. RESULTS: Up to 102 CFU/ml of Mtb were detected in the SPU in all methods, except for the Roche extraction/detection method, regardless of the preanalytical sample condition. In BAL samples, medium and high concentrations of cells and high concentrations of red blood cells contributed to a lower Mtb detection, regardless of the extraction method used. In PF, red blood cells were the variable that most interfered with Mtb detection, with better recovery (102 CFU/ml) observed with the Qiagen/Nanogen combination. CONCLUSION: The choice of Mtb extraction and detection method is of fundamental importance for PCR analytical sensitivity, especially when paucibacillary samples and/or samples containing potential PCR inhibitors are analyzed.

ABSTRACT

Carcinomas brônquicos, com maior frequência os adenocarcinomas, linfomas e carcinoma de mama, constituem 75% das causas de derrame pleural maligno (DPM). Para utilização das diversas opções terapêuticas paliativas disponíveis deve ser considerada uma avaliação multidisciplinar do estado do paciente, em conjunto com a experiência do profissional médico assistente, a capacidade técnica da instituição onde o tratamento será realizado e o custo-benefício AU.


Lung cancer, more often adenocarcinomas, lymphomas and breast carcinoma, are 75.0% of the causes of malignant pleural effusion. Palliative therapeutic options should be considered a multidisciplinary assessment of the patient's condition, together with the experience of the physician assistant professional, technical capacity of the institution where the treatment will be carried out and cost-effective AU.

ABSTRACT

OBJETIVO: Descrever características clínicas e laboratoriais em pacientes com derrames pleurais linfocíticos secundários a tuberculose ou linfoma, a fim de identificar as variáveis que possam contribuir no diagnóstico diferencial dessas doenças. MÉTODOS: Estudo retrospectivo com 159 pacientes adultos HIV negativos com derrame pleural linfocítico secundário a tuberculose ou linfoma (130 e 29 pacientes, respectivamente) tratados no Ambulatório da Pleura, Instituto do Coração, Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, São Paulo (SP), entre outubro de 2008 e março de 2010. RESULTADOS: A média de idade e de duração dos sintomas foi menor no grupo tuberculose que no grupo linfoma. Os níveis pleurais de proteínas, albumina, colesterol, amilase e adenosina desaminase (ADA), assim como os níveis séricos de proteínas, albumina e amilase, foram maiores no grupo tuberculose, enquanto os níveis séricos de colesterol e triglicérides foram maiores no grupo linfoma. As contagens de leucócitos e linfócitos no líquido pleural foram maiores no grupo tuberculose. Células malignas estavam ausentes no grupo tuberculose, entretanto, linfócitos atípicos foram observados em 4 desses pacientes. No grupo linfoma, a citologia para células neoplásicas foi positiva, suspeita e negativa em 51,8%, 24,1% e 24,1% dos pacientes, respectivamente. A imunofenotipagem do líquido pleural foi conclusiva na maioria dos pacientes com linfoma. CONCLUSÕES: Nossos resultados demonstram semelhanças clínicas e laboratoriais entre os pacientes com tuberculose ou linfoma. Embora os níveis de proteínas e ADA no líquido pleural tendam a ser mais elevados no grupo tuberculose que no grupo linfoma, mesmo essas variáveis mostraram uma sobreposição. Entretanto, nenhum paciente com tuberculose apresentou níveis de ADA no líquido pleural inferiores ao ponto de corte (40 U/L).


OBJECTIVE: To describe clinical and laboratory characteristics in patients with tuberculosis-related or lymphoma-related lymphocytic pleural effusions, in order to identify the variables that might contribute to differentiating between these diseases. METHODS: This was a retrospective study involving 159 adult HIV-negative patients with tuberculosis-related or lymphoma-related lymphocytic effusions (130 and 29 patients, respectively), treated between October of 2008 and March of 2010 at the Pleural Diseases Outpatient Clinic of the University of São Paulo School of Medicine Hospital das Clínicas Heart Institute, in the city of São Paulo, Brazil. RESULTS: Mean age and the mean duration of symptoms were lower in the tuberculosis group than in the lymphoma group. The levels of proteins, albumin, cholesterol, amylase, and adenosine deaminase (ADA) in pleural fluid, as well as the serum levels of proteins, albumin, and amylase, were higher in the tuberculosis group, whereas serum cholesterol and triglycerides were higher in the lymphoma group. Pleural fluid leukocyte and lymphocyte counts were higher in the tuberculosis group. Of the tuberculosis group patients, none showed malignant cells; however, 4 showed atypical lymphocytes. Among the lymphoma group patients, cytology for neoplastic cells was positive, suspicious, and negative in 51.8%, 24.1%, and 24.1%, respectively. Immunophenotyping of pleural fluid was conclusive in most of the lymphoma patients. CONCLUSIONS: Our results demonstrate clinical and laboratory similarities among the patients with tuberculosis or lymphoma. Although protein and ADA levels in pleural fluid tended to be higher in the tuberculosis group than in the lymphoma group, even these variables showed an overlap. However, none of the tuberculosis group patients had pleural fluid ADA levels below the 40-U/L cut-off point.

ABSTRACT

OBJECTIVES: To evaluate the effectiveness and safety of pleurodesis carried out entirely on an outpatient basis in patients with recurrent malignant pleural effusions and Karnofsky Performance Status scores <70. METHODS: This study was a prospective trial comprising patients with symptomatic recurrent malignant pleural effusion and Karnofsky Performance Status scores <70 but >30. All selected patients underwent pleural catheter placement (14 Fr) in an outpatient facility. When chest radiography revealed post-drainage lung expansion of >90 percent, pleurodesis (3 g of talc) was performed. Catheters were maintained until the daily output was ,100 mL/day. The patients were evaluated in the first month and every three months thereafter for fluid recurrence, the need for additional procedures, and complications. RESULTS: During the study period (January 2005 to July 2007), 64 patients (24 men, 40 women), with an average age of 61.4 years, underwent elective chest tube drainage. Primary sites of the underlying malignancy were breast (27), lung (22), and others (15). Sixty-six pleural catheters were placed (bilaterally in 2 patients), and 52 talc pleurodesis procedures were performed. Fourteen patients had a trapped lung and were excluded from the trial. No complications were observed during catheter placement or pleurodesis. Post-pleurodesis complications included catheter obstruction (4 patients) and empyema (1). The average drainage time was 9.9 days. The recurrence rate observed in patients that were alive 30 days after pleurodesis was 13.9 percent (5/36 patients). Six patients required additional procedures after the pleurodesis. The average survival time was 101 days. CONCLUSION: In this study, talc pleurodesis was safely performed in an outpatient setting with good efficacy and a reasonable complication rate, thereby avoiding hospital admission.

ABSTRACT

OBJETIVO: A pleurodese é uma alternativa eficaz no controle dos derrames pleurais malignos, mas existem controvérsias a respeito de sua indicação e técnica. O objetivo deste estudo foi avaliar como é realizada a pleurodese em países da América do Sul e Central. MÉTODOS: Profissionais que realizam pleurodese responderam um questionário sobre critérios de indicação para pleurodese, técnicas utilizadas e desfechos. RESULTADOS: Nossa amostra envolveu 147 profissionais no Brasil, 49 em outros países da América do Sul e 36 em países da América Central. Mais de 50 por cento dos participantes realizavam pleurodese somente se confirmada a malignidade no derrame pleural. Entretanto, escalas de dispneia e de status de performance eram raramente utilizadas para indicar o procedimento. Aproximadamente 75 por cento dos participantes no Brasil e na América Central preferiam realizar a pleurodese somente no caso de recidiva do derrame, e a expansão pulmonar deveria variar de 90 por cento a 100 por cento. O talco slurry foi o agente mais utilizado, instilado via drenos de calibre intermediário. A toracoscopia foi realizada em menos de 25 por cento dos casos. Febre e dor torácica foram os efeitos adversos mais comuns, e empiema ocorreu em < 14 por cento dos casos. A média de sobrevida após o procedimento variou entre 6 e 12 meses. CONCLUSÕES: Há variações consideráveis quanto aos critérios de indicação para pleurodese, técnicas utilizadas e desfechos entre os países. Talco slurry é o agente mais frequentemente utilizado, e a toracoscopia é a primeira escolha no Brasil. Os baixos índices de complicações e o tempo de sobrevida elevado indicam que a pleurodese é efetiva e causa poucos efeitos adversos.


OBJECTIVE: Pleurodesis is an effective alternative for the control of malignant pleural effusions. However, there is as yet no consensus regarding the indications for the procedure and the techniques employed therein. The objective of this study was to evaluate how pleurodesis is performed in South and Central America. METHODS: Professionals who perform pleurodesis completed a questionnaire regarding the indications for the procedure, the techniques used therein, and the outcomes obtained. RESULTS: Our sample comprised 147 respondents in Brazil, 49 in other South American countries, and 36 in Central America. More than 50 percent of the respondents reported performing pleurodesis only if pleural malignancy had been confirmed. However, scores on dyspnea and performance status scales were rarely used as indications for the procedure. Nearly 75 percent of the respondents in Brazil and in Central America preferred to perform pleurodesis only for recurrent effusions and stated that lung expansion should be 90-100 percent. Talc slurry, instilled via medium-sized chest tubes, was the agent most often employed. Thoracoscopy was performed in less than 25 percent of cases. Fever and chest pain were the most common side effects, and empyema occurred in < 14 percent of cases. The mean survival time after the procedure was most often reported to be 6-12 months. CONCLUSIONS: There was considerable variation among the countries evaluated in terms of the indications for pleurodesis, techniques used, and outcomes. Talc slurry is the agent most commonly used, and thoracoscopy is the technique of choice in Brazil. Pleurodesis is an effective procedure that has few side effects, as evidenced by the low complication rates and high survival times.

ABSTRACT

OBJECTIVE: The aim of this study was to identify the participation of the coagulation system in the differential diagnosis of pleural effusions. INTRODUCTION: Imbalance between immunologic and metabolic factors triggers a sequence of events resulting in pleural reactions and accumulation of fluid. The coagulation system, which is fundamental for the maintenance of homeostasis, contributes to the inflammatory process responsible for pleural effusions, and participates in cellular proliferation and migration as well as in the synthesis of inflammatory mediators. METHODS: We evaluated the laboratory profile of coagulation and fibrinolysis in 54 pleural fluids (15 transudates and 39 exudates). RESULTS: The coagulation system acts according to the pathophysiologic mechanisms involved in the development of pleural effusions. In inflammatory effusions (exudates), there is activation of coagulation with increased levels of fragment 1+2 and thrombin-antithrombin complex in addition to reduction of fibrinogen levels due to fibrinolysis and fibrin tissue incorporation. As a consequence, there is activation of the fibrinolytic system with increased levels of fibrin degradation products, including the D-dimer. These changes are not sufficient for differentiation of different subgroups of exudates. In transudates, these events were observed to a lesser degree. CONCLUSION: The coagulation system plays an important role in the development of pleural diseases. Coagulation tests show differences between transudates and exudates but not among exudate subgroups. Understanding the physiopathological mechanisms of pleural disorders may help to define new diagnostic and therapeutic approaches.

ABSTRACT

OBJETIVOS: Avaliar a experiência com o diagnóstico e a terapêutica do mesotelioma pleural maligno (MPM) acumulada durante 5 anos em um hospital público terciário. MÉTODOS: Avaliação retrospectiva dos prontuários dos pacientes com diagnóstico de MPM entre janeiro de 2000 e fevereiro de 2005. RESULTADOS: Foram analisados 17 pacientes, 14 homens e 3 mulheres, com idade média de 54,1 (13-75) anos. Os espécimes de biópsia para exame histopatológico foram obtidos por meio de pleuroscopia em 9 pacientes (53 por cento), agulha de Cope em 5 (29,5 por cento) e biópsia pleural aberta em 3 (17,5 por cento). Os tipos histológicos foram: epitelial em 14 pacientes (82 por cento), sarcomatóide em 1 (6 por cento) e bifásico em 2 (12 por cento). As terapêuticas instituídas foram: multimodal (pleuropneumonectomia com radioterapia e quimioterapia adjuvante) em 6 pacientes (35 por cento), quimioterapia e radioterapia em 6 (35 por cento), radioterapia exclusiva em 3 (17,5 por cento) e quimioterapia exclusiva em 2 (12 por cento). A sobrevida média foi de 11 (1-26) meses. CONCLUSÕES: Na presente experiência foi empregada a abordagem multidisciplinar integrada, e contou-se com uma estrutura hospitalar de alta complexidade para o diagnóstico e tratamento do MPM, como preconizado na literatura. Apesar disso, a sobrevida média observada foi de apenas 11 meses, refletindo a agressividade da doença.


OBJECTIVE: To evaluate the experience in diagnosing and treating malignant pleural mesothelioma (MPM) accumulated over 5 years in a tertiary public hospital. METHODS: The medical charts of the patients diagnosed with MPM between January of 2000 and February of 2005 were evaluated retrospectively. RESULTS: Of the 17 patients analyzed, 14 were male and 3 were female. The mean age was 54.1 years (range, 13-75 years). The biopsy specimens for histopathological examination were obtained through thoracoscopy in 9 patients (53 percent), Cope needle in 5 (29.5 percent), and open pleural biopsy in 3 (17.5 percent). The following histological types were identified: epithelial, in 14 patients (82 percent); sarcomatoid, in 1 (6 percent); and biphasic, in 2 (12 percent). The therapeutic approaches used were as follows: multimodal (pleuropneumonectomy and adjuvant radiotherapy and chemotherapy) in 6 patients (35 percent); chemotherapy and radiotherapy in 6 (35 percent); radiotherapy alone in 3 (17.5 percent); and chemotherapy alone in 2 (12 percent). The mean survival was 11 months (range, 1-26 months). CONCLUSIONS: In the cases studied, an integrated multidisciplinary approach was used, and a highly complex hospital infrastructure was available for the diagnosis and treatment of MPM, as recommended in the literature. However, the mean survival was only 11 months, reflecting the aggressiveness of the disease.

ABSTRACT

O derrame pleural neoplásico é uma complicação freqüente nos pacientes portadores de tumores avançados. A presença de células malignas no líquido pleural ou na biópsia da pleura é indicativa de disseminação da doença primária, com conseqüente redução da expectativa de vida. O diagnóstico e tratamento precoce do derrame pleural maligno são fundamentais para promover uma melhor qualidade de vida aos pacientes portadores de câncer avançado.


The malignant pleural effusion is a frequent complication in patients with of advanced tumors. The presence of malignant cells in the pleural fluid or in the pleural biopsy is indicative of dissemination of the primary disease, with consequent reduction of life expectancy. The early diagnosis and treatment of the malignant effusion is pivotal in promoting a better quality of life to patients with advanced cancer.

ABSTRACT

Foram estudados quinze portadores de pneumopatia por amiodarona com idades entre 52 e 79 (média 64,0) anos, sendo onze homens e quatro mulheres. Em 66% dos pacientes a dose diária de amiodarona foi 200 mg. O tempo decorrido entre o início da droga e o aparecimento da pneumonite foi de 2 a 84 (média = 23,3) meses. Extra-sistóles ventricularres e taquicardia paroxistica supraventricular foram as indicaçöes para o uso da droga. As principais queixas foram dispnéia progressiva e tosse. Emagrecimento foi observado em cinco, febre em seis e dor de características pleurais em dois pacientes. Ao exame físico do tórax houve predomínio de estertores sub-crepitantes difusos. Na radiografia de tórax observou-se infiltrado intersticial bilateral em todos, com derrame pleural em dois, e a cintilografia com citrato de gálio 67, realizada em nove pacientes evidenciou hipercaptaçäo difusa. A funçäo pulmonar mostrou insuficiência respiratória ventilatória restritiva, com hipoxemia. Dez pacientes foram submetidos a biópsia pulmonar, um a lavado bronco-alveolar, e outro a toracocentese. Nos três restantes, o diagnóstico se baseou em critérios clínicos e radiológicos. O material foi examinado a microscopia óptica e eletrônica. A partir da suspeita de toxicidade pulmonar, a droga foi suspensa em todos, introduziu-se corticoterapia em 13. Cinco (33,3%) pacientes faleceram, oito curaram-se e dois permaneceram sem seqüelas

ABSTRACT

Com o objetivo de avaliar a utilidade da determinaçäo da distribuiçäo porcentual das isoenzimas da desidrogenase lática no líquido pleural, foram estudados 26 pacientes com idade de 48 a 83 anos (média 63,5 anos). Seis eram portadores de derrame pleural por insuficiência cardíaca, seis por neoplasia, cinco após revascularizaçäo do miocárdio, dois por empiema, três por tuberculose e quatro idiopáticos. Os líquidos pleurais foram classificados em cinco tipos, de acordo com a classificaçäo de Vergon. Tipo I - samatória das isoenzimas 1,2 e 3 maior que 70%. Tipo II - semelhante ao I com isoenzima 5 maior que 15%. Tipo III - somatória das isoenzimas 4 e 5 maior que 60%. Tipo IV - aumento progressivo das isoenzimas de 1 a 5; Tipo V - distribuiçäo equitativa das isoenzimas. Cinco pacientes com insuficiência cardíaca foram classificados no tipo I e um no tipo V. As neoplasias de distribuíram nos tipos I (2), III (1), IV (1) e V (2). Dois derrames pós-revascularizaçäo encontraram-se no tipo I, e no IV e 1 no V. Os pacientes com empiema foram classificados como tipo IV. Os derrames tuberculosos distribuíram-se nos tipos I)1), IV(1) e V(1). Quanto aos idiopáticos, um caso encontrou-se no tipo III e três no V. A análise isolada do DHL5 revelou estar esta isoenzima elevada nos quatro casos de neoplasia em que o derrame foi hemorrágico. O mesmo achado se encontrou em pós revascularizaçäo e no empiema. Concluímos que a análise das fraçöes da DHL näo foi útil como marcador de neoplasia

ABSTRACT

Foram estudados seis pacientes portadores de pneumopatia por amiodarona com idades entre 58 e 66 anos, sendo quatro homens e duas mulheres. As principaos queixas foram tosse e dispnéia progressiva. Cinco deles utilizavam 200 mg diários da droga e um 400 mg/dia. O tempo decorrido entre o início de uso do medicamento e o aparecimento da pneumopatia foi de 13 a 84 meses (X = 39,8 m). A radiografia de tórax de todos revelou infiltrado intersticial difuso bilateral, e a cintilografia pulmonar com citrato de gálio 67, realizada em cinco pacientes, evidenciou hipercaptaçäo difusa. As provas de funçäo pulmonar mostraram insuficiência respiratória ventilatória restritiva. Hipoxemia esteve presente em todos os casos. Todos foram submetidos a biopsia pulmonar e um deles ao lavado bronco alveolar. O material obtido foi analisado à microscopia óptica e eletrônica; inclusöes lamelares foram encontradas em quatro pacientes. A amiodaroma foi suspensa e corticosteróides foram administrados a todos eles, sendo que três evoluiram para óbito e três apresentaram melhora clínica
