RESUMO

Lung transplantation (LTx) is the last-resort treatment for end-stage respiratory insufficiency, whatever its origin, and represents a steadily expanding field of endeavor. Major developments have been impelled over the years by painstaking efforts at LTx centers to improve donor and recipient selection, and multifaceted attempts have been made to meet the challenges raised by surgical management, perioperative care, and long-term medical complications. The number of procedures has increased, leading to improved post-LTx prognosis. One consequence of these multiple developments has been a pruning away of contraindications over time, which has, in some ways, complicated the patient selection process. With these considerations in mind, the Francophone Pulmonology Society (Société de Pneumology de Langue Française [SPLF]) has set up a task force to produce up-to-date working guidelines designed to assist pulmonologists in managing end-stage respiratory insufficiency, determining which patients may be eligible for LTx, and appropriately timing LTx-center referral. The task force has examined the most recent literature and evaluated the risk factors that continue to limit patient survival after LTx. Ideally, the objectives of LTx are to prolong life while improving quality of life. The guidelines developed by the task force apply to a limited resource and are consistent with the ethical principles described below.

RESUMO

In the context of lung transplant (LT), because of diagnostic difficulties, antibody-mediated rejection (AMR) remains a matter of debate. We retrospectively analyzed an LT cohort at Foch Hospital to demonstrate the impact of AMR on LT prognosis. AMR diagnosis requires association of clinical symptoms, donor-specific antibodies (DSAs), and C4d(+) staining and/or histological patterns consistent with AMR. Prospective categorization split patients into four groups: (i) DSA positive, AMR positive (DSA(pos) AMR(pos) ); (ii) DSA positive, AMR negative (DSA(pos) AMR(neg) ); (iii) DSA limited, AMR negative (DSA(Lim) ; equal to one specificity, with mean fluorescence intensity of 500-1000 once); and (iv) DSA negative, AMR negative (DSA(neg) ). AMR treatment consisted of a combination of plasmapheresis, intravenous immunoglobulin and rituximab. Among 206 transplanted patients, 10.7% were DSA(pos) AMR(pos) (n = 22), 40.3% were DSA(pos) AMR(neg) (n = 84), 6% were DSA(Lim) (n = 13) and 43% were DSA(neg) (n = 88). Analysis of acute cellular rejection at month 12 showed higher cumulative numbers (mean plus or minus standard deviation) in the DSA(pos) AMR(pos) group (2.1 ± 1.7) compared with DSA(pos) AMR(neg) (1 ± 1.2), DSA(Lim) (0.75 ± 1), and DSA(neg) (0.7 ± 1.23) groups. Multivariate analysis demonstrated AMR as a risk factor for chronic lung allograft dysfunction (hazard ratio [HR] 8.7) and graft loss (HR 7.56) for DSA(pos) AMR(pos) patients. Our results show a negative impact of AMR on LT clinical course and advocate for an early active diagnostic approach and evaluation of therapeutic strategies to improve prognosis.

RESUMO

INTRODUCTION: Lung transplantation (LT) is associated with an increased risk of infection, cancer, chronic renal failure, cardiovascular disease and osteoporosis. Some risk factors precede transplantation and could benefit for early diagnosis and optimised care. METHODS: The incidence of comorbidities and their treatment before referral were assessed in 157 consecutive lung transplant candidates between 2008 and 2011. RESULTS: The median age was 37years [25; 51]. Fifty-six percent had a body mass index below 19kg/m(2). In the COPD group, only 50 % had undergone a pulmonary rehabilitation program in the preceding 2 years. Osteoporosis was present in 42 %, of whom 36 % were on bisphophonate therapy. Vitamin D deficiency was present in 65 %. Previously undiagnosed cardiovascular risk factors were discovered during LT assessment: hypertension in one patient, hypercholesterolemia in 6 % and diabetes in 4 %. Poor dental condition necessitating extractions were found in 41 % of patients. Protective anti-HBs antibodies levels were present in 50 % of the patients at the time of referral. CONCLUSION: The assessment and early treatment of nutritional disorders, osteoporosis and risk factors for infection as well as addressing associated cardiovascular risk factors should be optimised in the care of patients with chronic respiratory insufficiency. The potential for becoming a lung transplant candidate in the future should be kept in mind early in the global management of those patients.

RESUMO

Nowdays adults with cystic fibrosis are no more attended in pediatric centers. Transition from pediatric to adult care centers must be anticipated. It requires the preparation of patients and families and a cooperation between both teams. Now, there are more patients and they are healthier. Adults centers caregivers have to pay particular attention to new young patients, to manage cystic fibrosis adult issues and to deal with more frequent comorbidities and severe complications. Adults centers will need better resources to maintain good quality of cares and improved life expectancy.

RESUMO

INTRODUCTION: About 15% of patients with haematological malignancy develop acute respiratory failure (ARF), necessitating admission to intensive care where their mortality is of the order of 50%. STATE OF THE ART: The prognosis of these patients is not determined by the pathological characteristics of the malignancy but by the cause of the acute respiratory failure. In effect, the need to resort to mechanical ventilation in the presence of dysfunction of other organs dominates the prognosis. Even if the use of non-invasive ventilation in these patients has reduced the need for intubation and reduced the mortality, its prolonged use in the most severely affected patients prevents the optimal diagnostic and therapeutic management. PERSPECTIVES: Fibreoptic bronchoscopy with broncho-alveolar lavage (BAL) is considered the cornerstone of aetiological diagnosis but its diagnostic effectiveness is poor, at best 50%, and this has led to increasing interest in high resolution CT scanning and regularly reawakens a transitory enthusiasm for surgical lung biopsy. Furthermore, in hypoxaemic patients, fibreoptic bronchoscopy with BAL may be the origin of the resort to mechanical ventilation, and thus increased mortality. The place of recently developed non-invasive tools is under evaluation. In effect, though the individual performance of diagnostic molecular techniques on sputum, blood, urine or naso- pharyngeal secretions has been established, the combination of these tools as an alternative to BAL has not yet been reported. CONCLUSION: This review deals with acute respiratory failure in patients with haematological malignancy. It includes a review of the recent literature and considers the current controversies, in particular the risk-benefit balance of fibreoptic bronchoscopy with BAL in severely hypoxaemic patients.

RESUMO

Exacerbation of prior pulmonary involvement may occur during neutropenia recovery. Granulocyte colony-stimulating factor (G-CSF)-related pulmonary toxicity has been documented in cancer patients, and experimental models suggest a role for G-CSF in acute lung injury during neutropenia recovery. We reviewed 20 cases of noncardiac acute respiratory failure during G-CSF-induced neutropenia recovery. Half the patients had received hematopoietic stem cell transplants. All patients experienced pulmonary infiltrates during neutropenia followed by respiratory status deterioration coinciding with neutropenia recovery. Neutropenia duration was 10 (4-22) days, and time between respiratory symptoms and the first day with more than 1000 leukocytes/mm3 was 1 (-0.5 to 2) day. Of the 20 patients, 16 received invasive or noninvasive mechanical ventilation, including 14 patients with acute respiratory distress syndrome (ARDS). Five patients died, with refractory ARDS. In patients with pulmonary infiltrates during neutropenia, G-CSF-induced neutropenia recovery carries a risk of respiratory status deterioration with acute lung injury or ARDS. Clinicians must maintain a high index of suspicion for this diagnosis, which requires eliminating another cause of acute respiratory failure, G-CSF discontinuation and ICU transfer for early supportive management including diagnostic confirmation and noninvasive mechanical ventilation.

RESUMO

Tuberculosis (TB) is a disease caused by Mycobacterium tuberculosis whose interaction with the host may lead to a cell-mediated protective immune response. The presence of interferon gamma (IFN-gamma) is related to this response. With the purpose of understanding the immunological mechanisms involved in this protection, the lymphoproliferative response, IFN-gamma and other cytokines like interleukin (IL-5, IL-10), and tumor necrosis factor alpha (TNF-alpha) were evaluated before and after the use of anti-TB drugs on 30 patients with active TB disease, 24 healthy household contacts of active TB patients, with positive purified protein derivative (PPD) skin tests (induration > 10 mm), and 34 asymptomatic individuals with negative PPD skin test results (induration < 5 mm). The positive lymphoproliferative response among peripheral blood mononuclear cells of patients showed high levels of IFN-gamma, TNF-alpha, and IL-10. No significant levels of IL-5 were detected. After treatment with rifampicina, isoniazida, and pirazinamida, only the levels of IFN-gamma increased significantly (p < 0.01). These results highlight the need for further evaluation of IFN-gamma production as a healing prognostic of patients treated.

RESUMO

We evaluated the mutations in a 193bp of the rpoB gene by automated sequencing of rifampicin (RMP)-resistant and susceptible Mycobacterium tuberculosis strains isolated from Brazil (25 strains) and France (37 strains). In RMP-resistant strains, mutations were identified in 100% (16/16) from France and 89% (16/18) from Brazil. No mutation was detected in the 28 RMP-susceptible strains. Among RMP-resistant or RMP-susceptible strains deletion was observed. A double point mutation which had not been reported before was detected in one strain from France. Among French resistant strains mutations were found in codons 531 (31.2%), 526, 513 and 533 (18.7% each). In Brazilian strains the most common mutations were in codons 531 (72.2%), 526 (11.1%) and 513 (5.5%). The heterogeneity found in French strains may be related to the fact that most of those strains were from African or Asian patients.

RESUMO

This article examines the principles of drug-user accountability. It examines the broader concepts of accountability in terms of individual responsibility (including criminal responsibility), the actions and the consequences of such actions, in terms of the self and others. Recent and prevailing governmental and public opinions are evaluated and appropriate sanctions are examined. Medico-legal aspects and dilemmas affecting the issues of the pathology of drug addiction and the nature and degree of impairment of responsibility as part of the addictive process, are analysed. A combined approach blending effective treatment, appropriate legal sanctions and community sanctions as an ultimate process to achieve demand and supply reduction universally, is proposed.

RESUMO

Many countries, including the Republic of South Africa, have introduced legislation providing for statutory treatment in cases of chemical substance dependence (addiction). Many more countries, including Canada and the United States of America, have made various attempts at the introduction of similar legislation in the face of an escalating drug abuse problem, only to have such legislation successfully challenged by various civil rights groups protesting about the "infringement of individual rights." This paper will examine some of the practical implications of coercive treatment of chemical addiction against the background of the principles of the rights of the individual. It will examine the feasibility of legal protection for such individual rights with simultaneous insistence on constructive treatment intervention. It will also raise many topics for discussion in terms of the role of the "helping professions", the well-worn tenet of "Am I my brother's keeper?" and the sociological poser of "the benefit of the community."
