Studies on lymphocytes obtained by bronchoalveolar lavage enable different parameters to be determined whose semiological value is discussed from information acquired in in vitro models of lymphocyte activation. These models show the need for activating signals acting in a sequential manner on cells whose function and mode of response are extraordinarily diversified. Three successive phases may be defined at the time of activation: first a membrane stage consisting of changes in the lipids (metabolism of arachidonic acid) and the cytoskeleton of the cell, a second stage corresponding to the start of the \"blastic transformation\" with the production of lymphokines with an increase in protein and RNA content (phase G1), then a third stage of DNA synthesis (phase S-G 2) preceding cell division; it is needed for the expression of new markers of differentiation. Nowadays the joint study of the phases of the cell cycle and the expression of antigenic differentiation, identified by monoclonal antibodies within a heterogeneous population, benefit from techniques of flow cytometry. These methods, combined with a measure of mediator production (interleukines) or of non-specific markers of activation liberated by T or B lymphocytes or by macrophages ought to succeed in defining the evolutionary stages or the immune-clinical types of alveolitis. Finally these methods allow the development of cellular immunopharmacology which should lead to new treatments.</p>","PeriodicalId":76480,"journal":{"name":"Revue francaise des maladies respiratoires","volume":"11 6","pages":"787-812"},"PeriodicalIF":0.0,"publicationDate":"1983-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17263921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data was supplied for 7 diagnostic groups defined according to List A of the International Classification of Diseases.

The comparisons between the urban and the rural background revealed an excess mortality for respiratory tuberculosis, lung cancer, bronchitis, emphysema and asthma for those in urban areas. In the rural environment an excess mortality was noted for acute respiratory diseases in both men and women; this was also found comparing agricultural to non-agricultural workers.

Amongst acute and sub-acute pathogens, bacterial infections produce a rapid poly-morpho-nuclear neutrophilia and then a lymphocytosis; oxygen and oxidising agents in general lead to a neutrophilia which amplifies the pulmonary parenchymal changes related to the release of toxic metabolites of oxygen. The inhalation of antigenic substances also disturbs the behaviour of alveolar cells: activation of macrophages in the presence of allergy in those sensitized to IgE and immediate attraction of neutrophils preceding a T lymphocyte alveolitis in hypersensitivity pneumonia. It is possible to categorise several patterns of reaction in intra-pulmonary cells when challenged by some insult, a direct cytotoxic action, the accumulation of inflammatory cells and immunological competence corresponding to the concept of \"a neutrophil alveolitis\" or a \"T cell alveolitis\" with the development of emphysematous lesions.

But long term oxygen therapy is costly and requires patient co-operation and close supervision. It should be reserved for hypoxic patients in a stable state: the exact degree of hypoxaemia at which oxygen therapy is permissible cannot be defined precisely and depends on other criteria (such as polycythaemia, pulmonary arterial hypertension, nocturnal desaturation).

Personal observations on these cases combined with 43 already described in the literature allow certain characteristics of the disorder to be accurately defined. Clinically, primary pulmonary hemangiopericytoma raises the aetiological problem of a peripheral solitary tumour beyond endoscopic vision. Until the present time the diagnosis has always been made by thoracotomy. Transpleural pulmonary biopsies may allow a preoperative diagnosis. Silver stains and electron microscopy enable an anatomo-pathological diagnosis. Histological studies can neither distinguish between benign and malignant forms nor differentiate between primary or metastatic hemangiopericytoma. For this reason there is always a long period of doubt whether the tumour is primary; only prolonged survival of the patients after excision will confirm whether the tumour was a primary or not. Treatment is essentially surgical. It seems that new techniques in radiotherapy (high energy) and new possibilities of chemotherapy (with Adriamycin) are capable of improving the prognosis of the malign form.

{"title":"[Respiratory handicap. Recognition, evaluation and social benefits].","authors":"J Marsac,&nbsp;J C Pujet","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The medico-social aspects of respiratory handicap pose some perplexing problems, notably in their recognition, rigorous evaluation and in the granting of social security benefits. The clinical and respiratory function data should be standardised and classified according to type and significance of respiratory disease and also according to the degree of co-operation and understanding of the patient. The respiratory handicap should be evaluated after considering the functional disability engendered by the disorder and their socio-professional repercussions. The abnormality in the lungs should be measured by resting tests; the degree of disability by exercise studies; the socio-professional handicap by ergonometric tests to assess the scale of the demands and requirements of family and social and professional life, indeed the cultural and economic style of the individual concerned. Such combined studies would enable recognition of severe chronic respiratory handicap leading to decisions for exemption certificates, such as cases of severe respiratory failure in patients requiring supplementary treatment for oxygen therapy or assisted ventilation. The benefits and grants offered to those with respiratory handicaps would involve a number of rights relating to: care, work, costs of replacement of workers in the event of prolonged sick leave or the benefits of an invalidity pension. There will be other allowances such as invalidity cards, lodging special studies and other rights particularly relating to lodging and special equipment. The present scale is difficult to use both because of its lack of specificity and its ill-chosen terminology. For better balance between the handicap and the benefits offered, a common and more flexible system, with a printed table should be at hand for the doctor to use for certain decisions: long term illness, period of invalidity or early retirement because of medical incapacity. Within each table a sub-section should exist to allow for certain aspects of legislation (accidents at work, occupational illness or rights under common law) at the same time certain adjustments may be necessary which take into account the patient, degree of autonomy life style and social and cultural level.

This level may be disputed if too many are lost to follow up or non-compliers appearing late. To understand the true failure rate we strove to trace every patient in a trial carried out between 1969 and 1973, consisting of three groups of patients treated with the same chemotherapy: Isoniazid (450 mg/day), Rifampicin (600 mg/day) given every day but for differing durations: 6 months (Group A), 9 months (Group B), 12 months (Group C), with either daily Ethambutol or Streptomycin in addition for the first three months. Amongst the 356 patients in the trial 86 were eliminated for failure to comply with the protocol, either due to a mishap or change of treatment. Amongst the 270 remaining patients, 248 were traced with a mean delay of post-therapy follow up of 101 months for patients still living and of 72 months for patients who had died in the intervening period, but of non-tuberculous disease. In the 242 old patients whose disease could be evaluated, the number of bacteriological relapses was 4/81 (6.2 %) in group A, and 2/85 (2.3 %) in group B and 2/76 (2.6 %) in group C. There was no significant differences between the groups. From these results it is seen that the Isoniazid/Rifampicin combination given daily for 6 months is a powerful combination with few failures.
