[Treatment of amyloidosis with dimethyl sulfoxide (DMSO)]. / Trattamento dell'amiloidosi con dimetilsulfossido (DMSO).

In this study we have investigated the role of oral dimethylsulfoxide (DMSO) therapy in 2 patients with primary amyloidosis (AL) and in 2 patients with secondary amyloidosis (AA) to long-standing rheumatoid arthritis. DMSO treatment produced no beneficial effects in the patients with idiopathic amyloidosis. Instead the patients with secondary amyloidosis experienced a subjective improvement, a decrease of inflammatory activity of the rheumatoid arthritis and an unequivocal improvement of renal function following 3-6 months of DMSO therapy. No serious side effects of DMSO were observed except for unpleasant breath odour. We conclude that a treatment with oral DMSO may prolong life of patients with secondary amyloidosis.

[Role of alpha 1-antitrypsin and alpha-2 macroglobulin in hepatopathies]. / Ruolo dell'alpa 1-antitripsina e dell'alfa 2-macroglobulina nelle epatopatie.

Two pictures of alpha 1-antitrypsin deficiency, one associated with alpha 2-macroglobulin deficiency and one isolated case of the latter deficiency have been observed in three patients suffering from cirrhosis of the liver and/or hepatoma. On the basis of these cases, the literature on the subject is reviewed. The unusually high incidence of such anti-enzymatic deficiencies (three cases in the first eleven patients studied) in severe liver pathology, calls for a reassessment of such research and suggests that these tests should be carried out on a routine basis in cases of cryptogenetic cirrhosis and probably for long-term prognosis in cases of viral hepatitis.

[Gamma glutamly transpeptidase in chronic anicteric hepatopathies]. / La gamma-glutamil-transpeptidasi nelle epatopatie cronich anitteriche

Serum levels of gammaGT were determined in 51 patients suffering from bioptically verified chronic anictereric liber disease. GammaGT proved to be much more sensitive than the other enzymes studied and presented a significant increase particularly in cases of steatosis and chronic "alcoholic" liver disease with a markedly steatosic character.

[Concentration and reinfusion of ascitic fluid in liver cirrhosis]. / La concentrazione e reinfusione dell'ascite nella cirrosi epatica.

46 concentration-reinfusion treatments were performed on 36 patients, suffering from refractory ascites for liver cirrhosis. The procedure was well tolerated, improved the status of the patients and enabled diuretic to be effective again, in some cases for as long as two years. The usefulness of infusing autologous, non-denatured proteins in high dosage is stressed. The Authors belive that hepatorenal syndrome, severe hypokaliemia or hyposodemia and encephalopathy are the elective indications for the treatment.

[Erythrocyte changes during alcoholism and chronic liver diseases]. / Alterazioni eritrocitarie in corso di etilismo e di epatopatie croniche.

50 patients with chronic liver disease and/or alcoholism were studied. 28 cases of anemia were found and macrocytes (and target m.), spurr-cells, spherocytes and stomatocytes observed. For each of these abnormalities the authors report the observed incidence and discuss the literature's data about the pathogenesis. A personal research on the influence of the liver's impaired capability of protein synthesis was also carried out. The usefulness of a careful examination of the blood film is finally stressed, in patients with liver disease and to discover alcoholic subjects still "healthy".

Different morphologic aspects and clinical features in massive hepatic amyloidosis.

4 cases of massive hepatic amyloidosis are reported with special reference to their clinical profiles and histologic features. On the basis of these data, two different clinical and histologic courses of the disease can be distinguished. 2 patients showed marked hepatomegaly without cholestasis, whereas in the other 2 the clinical picture was characterized by much less pronounced hepatomegaly, but by severe and progressive intrahepatic cholestasis. The time course of the disease seems to be different in the two forms, the cholestatic form being more rapidly fatal than the other.

[Behavior of some acute phase reactant proteins during phlogosis and neoplasms and their correlation with erythrocyte sedimentation rate]. / Comportamento di alcune proteine della fase acuta in corso di flogosi e di neoplasie, e loro correlazione con la V.E.S.

Alpha 2 macroglobulin, haptoglobin and fibrinogen plasma levels were simultaneously determined, as well as E.S.R., to test if a significant difference could be found among cancer, inflammatory diseases and control subjects. Haptoglobin was higher in the cancer group and fibrinogen in inflammatory diseases, but these selective increases are not believed to be enough to suggest the widespread determinations of these proteins. A significant correlation was found between alpha 2 macroglobulin and E.S.R., as well as between fibrinogen and E.S.R.
