Nine FMD and 17 AS patients had renal vein renin ratios greater than or equal to 1.50 under unstimulated conditions. Of these 26 patients, 8 in each group improved after surgical treatment. Among the 14 FMD and 24 AS patients with ratios less than 1.50, another 9 FMD and 7 AS patients improved after operation. After acute stimulation of renin release, no less than 18 FMD and 26 AS patients had a unilateral renin secretion from the diseased kidney and of these, 14 FMD and 14 AS patients were successfully treated with operation of the stenosis. Thus the stimulation was necessary for correct preoperative diagnosis in 38% of 32 successfully operated patients, and at the same time the predictive value of a negative test increased from 0.58 to 0.80.

Non-ischaemic diseases needing specific therapy were revealed in six patients. In the other 12 patients echocardiography demonstrated myocardial lesions explaining the mitral regurgitation. Apart from the distinction between non-ischaemic conditions and lesions induced by ischaemia, echocardiography seems to be helpful in the demonstration of severe yet operable mitral valve regurgitation due to a small ischaemic lesion. Such cases are opposed to functional mitral regurgitation caused by extensive myocardial injury as demonstrated by two-dimensional echocardiography and reflected by a minimum mitral valve/septum separation of more than 2 1/2 cm on the M-mode echocardiogram. These conditions make symptomatic improvement by mitral valve surgery unlikely and carry an extremely high operative mortality. A more precise definition by heart catheterization is required when serious clinical heart failure is not explained by the echocardiographic finding of severe global myocardial impairment.</p>","PeriodicalId":7011,"journal":{"name":"Acta medica Scandinavica","volume":"216 3","pages":"243-9"},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17553890","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}

The present study was made to further study the iron metabolism in runners as the proposed cause of \"sports anemia\" is abstruse considering the good iron nutrition in these athletes. Based on a screening of 43 elite male runners, using bone marrow hemosiderin, serum ferritin and transferrin saturation, two groups of subjects were selected for a very extensive study on iron metabolism. In group 1 (n = 5) iron depletion was suggested in at least one of the screening studies. In group 2 (n = 7) at least one test strongly indicated good iron repletion. This experimental design was chosen to obtain two groups with similar body composition and exercise load but different iron metabolism. The studies comprised determinations of red cell and plasma volumes, plasma iron turnover and red cell incorporation of radioiron, red cell indices, plasma iron and transferrin, red cell protoporphyrin, serum ferritin, serum haptoglobin, urinary iron losses, iron absorption, bone marrow hemosiderin, dietary intake of energy and nutrients and a Desferal test.

The hematocrit, serum iron, transferrin saturation and serum ferritin values were significantly lower in the athletes. The amount of bone marrow hemosiderin was also lower in the athletes than in a group of non-athletic men of the same age. Even if these values were clearly lower than in the controls, they were not low enough to indicate iron deficiency. The observations that sideroblast counts in bone marrow smears were normal and that both red cell indices and red cell protoporphyrin were normal strongly support the conclusion that lack of iron had not limitated erythropoiesis or the formation of an optimal red cell mass. Low serum haptoglobin values in most athletes indicated an increased intravascular hemolysis. As the hemoglobin-haptoglobin complex formed is taken up by hepatocytes, this implies that there is a shift in the red cell catabolism in these athletes from the reticuloendothelial system to the hepatocytes. This shift may explain the paradoxical findings of low serum ferritin concentrations and reduced contents of bone marrow hemosiderin. This is consistent with the observed normal erythropoiesis. It was concluded that runners \"anemia\" is no true anemia and not caused by iron deficiency. \"Sports anemia\" is thus no indication for routine iron supplementation.</p>","PeriodicalId":7011,"journal":{"name":"Acta medica Scandinavica","volume":"216 2","pages":"157-64"},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17553203","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}

Beside monoclonal macroglobulinemia there are conditions with a high content of polyclonal IgM and also of IgG and IgA where hyperviscosity is a dominant symptom. The importance of what may be called macroglobulinemia polyclonalis spuria is stated and a number of patients belonging to this type are discussed. Polyclonal increase in IgG, even at high levels, usually does not cause severe hyperviscosity. Case histories of patients with rheumatoid disease and marked hyperviscosity constitute one group. Another is formed by diseases leading to the development of immune complexes. Such complexes are usually caused by binding of polyclonal IgG to monoclonal IgM, but other combinations are also known. A number of clinical examples of these different disease conditions, some probably indicating intense plasmapheresis, are analyzed. The limited value of plasmapheresis alone without cytostatic treatment is stressed as regards hyperviscosity. Another indication is removal of noxious protein components.</p>","PeriodicalId":7011,"journal":{"name":"Acta medica Scandinavica","volume":"216 5","pages":"467-74"},"PeriodicalIF":0.0,"publicationDate":"1984-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17303260","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}
