Two quite dyspneic HIV positive patients were admitted to the Emergency Room; they presented with aspects and images suggesting pericardial effusion. The analysis of an initial liquid puncture did not show any specificity and the patients did not register any clinical improvement. Both patients were submitted to a subxiphoid pericardial window, all the effusion liquid was drained, and a biopsy of the pericardium tissue was completed revealing a granulomatous process. Good evolution was the result of specific treatment. Such findings draw attention to a high possibility of pericardial suffusion in AIDS patients being tuberculosis, in particular if one considers the high prevalence of this disease in Brazil. The results also showed that the opening of a subxiphoid pericardial window and the specific triple scheme is a procedure that leads to good therapeutic evolution in this kind of patients.

A pneumonia por Pneumocystis carinii (PPC), que é a infecção oportunista que mais comumente põe em risco a vida de pacientes com síndrome da imunodeficiência adquirida (SIDA), tem sido há bastante tempo associada a outros estados de imunodeficiência. Os relatos iniciais sugeriram que a apresentação clínica da PPC em SIDA difere de sua apresentação em outras situações, embora ambas tenham sofrido modificações nos últimos anos. O objetivo do presente estudo é comparar os achados clínicos e laboratoriais da PPC em SIDA com os de pacientes portadores de PPC sem SIDA. Foram revisados os prontuários médicos de todos os pacientes em nossa instituição que tiveram o diagnóstico confirmado de PPC e SIDA durante o ano de 1994 (17 pacientes) e sem SIDA no período de 1992-1994 (dez pacientes). Quando da apresentação, os pacientes sem SIDA tinham uma duração de sintomas significativamente menor (8,4 ± 7,7 vs 19,5 ± 10,2 dias, p < 0,05), menor PaO2 média a ar ambiente (47 ± 8,2 vs 63 ± 10mmHg, p < 0,05), e mais freqüente infiltrado unilateral no radiograma do tórax (60 vs 6%, p < 0,05). O índice de mortalidade da PPC foi marcadamente maior nos pacientes sem SIDA (40 vs 6%, p < 0,05), e este fato estava associado com retarde no início do tratamento específico nestes pacientes. Devido a seu curso mais agudo, apresentação radiológica atípica e alto índice de mortalidade, concluímos que o diagnóstico de PPC deve ser afastado em pacientes que recebem terapia imunossupressora e que profilaxia anti-PPC deve ser fortemente considerada em pacientes que serão imunossuprimidos.

Microsporidiosis is a rapidly emerging protozoon infection that has been reported predominantly in severely immunosuppressed persons with acquired immunodeficiency syndrome (AIDS). Since the first case of human microsporidian infection was reported in 1956, over 400 cases have been documented. The initial description of microsporidian infection in AIDS patients occurred in 1985. Five genera have been identified as the agents of microsporidiosis in immunocompromised persons (Enterocytozoon, Encephalitozoon, Septata, Pleistophora and Nosema). Respiratory tract infection due to microsporidia is associated almost exclusively with disseminated disease produced by members of the genera Encephalitozoon and Septata. Metronidazole and albendazole were recently reported to be responsible for clinical improvement of patients. The authors reported a case of a woman with AIDS and respiratory symptoms related to two pulmonary pathogens: Mycobacterium tuberculosis and Encephalitozoon cuniculi, identified by polymerase chain reaction (PCR) using diagnostic primers targeting the small subunit ribosomal RNA.

Chronic obstructive pulmonary disease is currently considered a systemic disease, presenting structural and metabolic alterations that can lead to skeletal muscle dysfunction. This negatively affects the performance of respiratory and peripheral muscles, functional capacity, health-related quality of life and even survival. The decision to prescribe ergogenic aids for patients with chronic obstructive pulmonary disease is based on the fact that these drugs can avert or minimize catabolism and stimulate protein synthesis, thereby reducing the loss of muscle mass and increasing exercise tolerance. This review summarizes the available data regarding the use of anabolic steroids, creatine, L-carnitine, branched-chain amino acids and growth hormones in patients with chronic obstructive pulmonary disease. The advantage of using these ergogenic aids appears to lie in increasing lean muscle mass and inducing bioenergetic modifications. Within this context, most of the data collected deals with anabolic steroids. However, to date, the clinical benefits in terms of increased exercise tolerance and muscle strength, as well as in terms of the effect on morbidity and mortality, have not been consistently demonstrated. Dietary supplementation with substances of ergogenic potential might prove to be a valid adjuvant therapy for treating patients with advanced chronic obstructive pulmonary disease, especially those presenting loss of muscle mass or peripheral muscle weakness.

Objetivo: Realizar a tradução para a língua portuguesa e a adaptação cultural para uso no Brasil do Quality of Communication Questionnaire (QOC) para pacientes com DPOC em cuidados paliativos. Métodos: Após a aprovação do autor do questionário e do comitê de ética da instituição, a versão original do QOC com 13 itens foi traduzida, de forma independente, por dois tradutores brasileiros com fluência na língua inglesa. Uma síntese das duas traduções foi realizada por uma médica bilíngue e os dois tradutores, que chegaram a um consenso, gerando uma versão na língua portuguesa. Essa versão foi retraduzida por dois tradutores nativos de países de língua inglesa com fluência na língua portuguesa. Para resolver quaisquer discrepâncias, um comitê de especialistas comparou a versão original com todas as versões produzidas e, assim, obteve-se a versão pré-final do QOC. O pré-teste foi aplicado em 32 pacientes internados em UTIs de três hospitais públicos da grande Florianópolis (SC) para avaliar a clareza e a aceitabilidade cultural da versão pré-final do QOC. Resultados: A média de idade dos pacientes foi de 48,5 ± 18,8 anos. A maioria dos itens foi bem compreendida e aceita, recebendo pontuações ≥ 8. Um item, sobre morte, suscitou dificuldades na compreensão dos participantes do pré-teste. Ao submeter a retradução ao autor do QOC, ele solicitou alterações em dois itens, que foram acatadas. Após essas alterações, a versão final foi aprovada. Conclusões: A tradução e a adaptação cultural do QOC para uso no Brasil foi concluída com sucesso.

Objective: To evaluate the epidemiological profile of patients with tuberculosis (TB) only and that of patients with TB/AIDS in the state of Espírito Santo, Brazil, between 2000 and 2006. Methods: For the patients of interest, we collected demographic and clinical data from the Epidemiological Surveillance Center (TB database), Brazilian Case Registry Database, and Brazilian National Mortality Database, as well as the Brazilian National CD4+/CD8+ T Lymphocyte Count and Viral Load Network Laboratory Test Control System and the Logistic Medication Monitoring System (HIV/AIDS databases). All of the compiled data were cross-referenced. Results: During the study period, we identified 9,543 TB patients > 15 years of age, 437 of whom (4.6%) had AIDS. The median age did not differ between TB/AIDS and TB-only patients (35 years vs. 38 years). Of the 437 TB/AIDS patients, 298 (68.2%) were male, and 156 (35.8%) were in the 30-39 age bracket. In terms of TB treatment outcome, 79.0% were cured, 9.7% were referred to other facilities, 6.0% died, 5.2% abandoned treatment, and 0.2% developed multidrug-resistant TB. Death was 4.75 times more common in patients with TB/AIDS than in those with TB only. Pulmonary TB accounted for 82.4% of the cases. The combination of pulmonary and extrapulmonary TB was 8.2 times more common in the TB/AIDS patients than in the TB-only patients (95% CI: 6.2-10.8). Conclusions: Our results emphasize the significance of AIDS among TB patients in Brazil, as well as the importance of evaluating secondary data in order to improve their quality and develop public health interventions.

Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome.

Background: Tuberculosis become important challenge to health care settings. Brazil has high prevalence of the disease and Rio de Janeiro has high incidence rates with 30% of cases notified at hospitals. Objective: To evaluate prevalence of initial and acquired drug resistance at a general hospital, reference for aids treatment in Rio de Janeiro and to identify associated factors. Methods: Mycobacterium tuberculosis strains from 165 patients were analyzed, between August 1996 and February 1998. Results: Twenty per cent (33/165) were resistant to at least one drug; 13% (12/165) to isoniazid; 3.64% (6/ 165) to rifampin and 3.64% (6/165) to both. Among HIV seropositive subjects (52/165); 28.85% (15/52) were resistant to at least one drug. Acquired resistance occurred in 15.79% of 19 patients that mentioned previous antiTB treatment. Association statistically significant was found with non cavitation on X-ray in bivariate analyses ( P=0.05). Eighty four patients refereed no previous treatment (NPT). Resistance to 1 or more drugs was found in 28.57% (24/84) of NPT patients. Association statistically significant with initial resistance was found with health care workers (P=0.004), unemployment (P=0.03), and diarrhea (P=0.01) in bivariate analyses. On multivariate analyses, health care workers ( P=0.002) remained significantly associated with initial resistance. Conclusions: High resistance rates was found. It corroborates that hospitals needs attention for TB control especially which concerns to health care works infection.

Background: Synergism between tuberculosis and HIV is responsible for the increased morbidity-mortality rate in AIDS patients. Objective: To delineate the profile of patients with tuberculosis and AIDS in the city of Rio Grande by relating demographic, clinical and laboratory data. Method: The sample comprised all cases of tuberculosis defined by identification of Mycobacterium tuberculosis that occurred in the AIDS Service of the University Hospital/FURG between September, 1997 and December, 2000, which added to a total of 31 patients confirmed as definite cases of AIDS. Using the Ogawa-Kudoh culture method and the Kinyoun bacilloscopy, 33 clinical pulmonary and extrapulmonary specimens were analyzed. Identification of M. tuberculosis was made by the usual phenotype methods. The method of proportions was chosen to establish resistance of isolated strains. Results: The mean age was of 33.8±9.9 years, with a man/woman ratio of 2.87:1 and 80.7% of Caucasians. All patients (n=31) exhibited overall or specific clinical manifestations of turberculosis at the time of suspicion diagnosis. In 20 of the cases risk factors were observed: use of injected drugs, alcoholism, malnutrition, imprisonment. Pulmonary disease occurred in 19 cases, extrapulmonary in 10 and the association of both in two. Lymph node commitment was more frequent among those with extrapulmonary disease. The isolated strains (33) were identified as M. tuberculosis and 28 were tested and showed sensibility to Isoniazid and Rifampin. Conclusion: In AIDS patients, tuberculosis appeared with various clinical manifestations, jeopardizing both men and women of less favored social conditions while at a fully productive stage of their lives.
