Biochemical abnormalities of the serum in anorexia nervosa.

Biochemical analyses of sera from 27 patients with anorexia nervosa were performed and compared with those of normal female volunteers and other anorectic groups including patients who had undergone digestive tract surgery and patients with malignancies. There were significant increases in gamma-glutamyltranspeptidase, lactate dehydrogenase, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, cholesterol, and amylase activity and significant decreases in total serum protein, blood sugar, albumin, globulins, and cholinesterase in anorexia nervosa patients compared with normal control subjects. At discharge, these values slightly improved. Similar alterations were also observed in two other anorectic groups. Compared with anorexia nervosa patients, the two other anorectic groups showed a severe reduction in the albumin level and increase in the globulin level. In two other anorectic groups cholesterol levels were lower, and in the malignancy group cholinesterase level was lower than in the anorexia nervosa patients. In anorexia nervosa patients, biochemical abnormalities in the serum were more frequent in total serum protein (93%), blood sugar (85%), and globulins (78%) than in other serum factors, such as blood urea nitrogen (15%), uric acid (15%), and alkaline phosphatase (7%). These results suggest that detection of biochemical abnormalities in the above-mentioned serum factors in routine analyses would be valuable in making an early diagnosis of anorexia nervosa from various anorectic disorders.

Primary mucociliary transport failure.

Among the disorders associated with male infertility and chronic sinopulmonary infections, primary ciliary dyskinesia or cystic fibrosis is characterized by ciliary dysfunction or abnormality of mucus secretion. In addition, Young's syndrome differs from the former because of the absence of ultrastructural cilia disorders and from the latter because of normal sweat and pancreatic functions. However, a number of manifestations seen in these disorders appear to overlap each other, e.g., male infertility and chronic sinopulmonary infections which often develop bronchiectasis. Therefore, I would like to propose that the term 'muco(secretion)ciliary transport failure' is used for illnesses in patients with primary impairment of mucosecretion and/or ciliary transport in organs containing the mucociliary transport system. Primary mucociliary transport failure encompasses three hereditary disorders, that is, primary ciliary dyskinesia, cystic fibrosis and Young's syndrome. Ciliary activity is closely associated with mucus production. For a better understanding of the relationship between ciliary activity and mucus production, further basic and clinical studies should be attempted.

A new syndrome: angiotensin-converting enzyme dysfunction syndrome: differential diagnosis and pathogenesis--case reports.

The authors previously reported a new syndrome, angiotensin-converting enzyme dysfunction syndrome (ACEDS), which is clinically characterized by mild systemic hypertension, a hypokalemic alkalosis, and hyperreninism with a high concentration of angiotensin-I (ANG-I), a normal angiotensin-II (ANG-II) value, and a normal aldosterone level. In the present study, they investigated the diagnosis and differentiation of diseases concomitant with hyperreninism, such as ACEDS, Bartter's syndrome, familial periodic paralysis, and renovascular hypertension treated with captopril for two months, and discussed the pathogenesis of ACEDS.

Alterations in serum lipid concentrations before and after myocardial infarction in a patient with hyperlipoproteinemia and sarcoidosis--a case report.

This report describes a sarcoidosis patient with a type II-b hyperlipoproteinemia who suffered acute myocardial infarction during corticosteroid therapy for sarcoidosis and whose blood lipid levels were assessed before and after the infarction. After the infarction occurred, lipoprotein analysis revealed a type II-a hyperlipoproteinemia concomitant with high free fatty acids, phospholipids, and HDL-cholesterol values; an increased ratio of total cholesterol to triglycerides; and a decreased ratio of very low density lipoproteins to total lipoproteins, suggesting that changes in types of hyperlipoproteinemia may be associated with the onset of myocardial infarction.

Gabexate as a therapy for disseminated intravascular coagulation.

The effects of gabexate mesilate on disseminated intravascular coagulation (DIC) accompanying neoplastic diseases or severe infections in ten patients were investigated and compared with those of heparin therapy in ten other patients with DIC. Of 11 patients with DIC (control) who did not receive any anticoagulation therapy for DIC, ten died of pneumonia, DIC secondary to the underlying diseases, or pulmonary edema. Heparin therapy was effective in five patients (50%), while treatment with gabexate was successful in seven patients (70%). Although the therapeutic efficacy of gabexate was not significantly different from that of heparin, in patients in whom bleeding tendencies were observed at the start of the therapy, the former was successful in four (80%) of five patients, while the latter was effective in only one (25%) of four patients treated. The results of this preliminary and nonrandomized study suggest that gabexate is as effective as heparin for the treatment of DIC, and that it may be more successful than heparin in the treatment of DIC accompanied by bleeding diathesis.

Sarcoidosis and acquired type II-b hyperlipoproteinaemia.

In four of eleven patients with histologically-proven sarcoidosis (stage II or III), type II-b hyperlipoproteinaemia (HLP) with increased levels of total cholesterol, triglycerides and low density lipoprotein, and a decreased level of high density lipoprotein was observed. These results suggest that type II-b HLP may be associated with sarcoidosis with systemic sarcoid infiltration (stage II or III).
