Non-A, non-B hepatitis not following transfusion: a study of hospital patients in Jerusalem.

An analysis of the etiology of acute viral hepatitis in 172 hospitalized patients showed that 70.9% suffered from hepatitis A (HA), 12.2% from hepatitis B (HB), 1.7% from infectious mononucleosis and 15.1% (26 cases) from non-A, non-B hepatitis. Patients who had received blood transfusions during the 6 mo preceding the onset of the disease were not included in the present survey. The male:female ratio in the patients with non-A, non-B hepatitis was 1:88; 73% were Ashkenazic and 27% non-Ashkenazic Jews. The ethnic distribution of patients with non-A, non-B hepatitis was similar to that of patients with HA but differed from that of HB patients (only 41% Ashkenazic). Thirty-eight percent of the non-A, non-B group had had contact with jaundiced patients during the 6 mo preceding the onset of the disease, and 46% were students or soldiers. The clinical course of the disease was, on the whole, milder than that of HB and similar to that of HA. Since many cases of non-A, non-B hepatitis are anicteric, it is concluded that the disease is a significant problem in Israel.

Histocompatibility antigens and cell-mediated immunity in carriers of hepatitis B virus; a study of a family.

The cause of the HBsAg carrier state is unknown, and environmental genetic and immunologic factors have been implicated. Herein, a family is described in which the carrier state was associated with the HLA-A28BW15 haplotype and with impaired cell mediated immunity. The relevance of the genetic marker in this family is uncertain. It could be associated with a genetic susceptibility to the virus or alternatively with inherited immunodeficiency. According to the first possibility the impaired immunity could be secondary to the persistent viral infection. According to the second one the acquisition of the carrier state could result from the inherited immune defect.

Effect of iron deficiency on transplantable murine plasmacytoma.

The effect of iron deficiency on tumour growth and on host survival was studied in BALB/c mice with transplanted Merwin Plasma Cell-II tumors. Iron deficiency was induced by maintaining the animals on an iron-free diet consisting of milk-cornflour supplemented with CuCl2 and vitamins A and D. Iron deficiency resulted in retardation of both body and tumor growth in weanling BALB/c mice. Their survival, however, was not significantly different from that of iron supplemented controls. The inhibitory effect of iron deficiency on host and tumour growth could not be reproduced in adult BALB/c mice. The survival of tumor-bearing hosts maintained on a milk-cornflour diet (whether supplemented with iron or not) was significantly longer than that of animals maintained on a purina diet.

Immunological evaluation of asymptomatic carriers of hepatitis B virus.

The immune system of 69 asymptomatic HBsAg carriers with normal liver function tests was evaluated. B cell function, as documented by serum immunoglobulin levels, number of mouse rosette-forming lymphocytes and lymphocyte reactivity to staphylococcal protein A, was intact. On the other hand, T cell function was markedly impaired. This was manifested by a significant decrease in E rosette-forming lymphocytes, an increase in stable rosette-forming cells and decreased reactivity to phytohaemagglutinin and concanavalin A. These data rule out the possibility that the immunological aberrations associated with hepatitis B infection are secondary to liver injury. The abnormal immune state either precedes the viral infection, thus predisposing to the acquisition of a carrier state or, alternatively, is a direct result of the infection.

Arterial embolism in thyrotoxicosis with atrial fibrillation.

The incidence of atrial fibrillation (AF) in 142 patients with thryotoxicosis was 21% and that of thromboembolic disease was 8.5%. Male sex, increasing age, and associated rheumatic or hypertensive heart disease were significantly associated with the presence of AF. Thromboembolic episodes occurred in 12 (40%) of the patients with AF and in none of the 112 patients without AF. Cerebral emboli accounted for 53% of the episodes. In view of the grave prognosis of the embolic episodes, patients with thyrotoxicosis should be treated with heparin during attacks of AF and with oral anticoagulants when they have chronic fibrillation.

Coexistence of pheochromocytoma and renal artery occlusion in a patient with malignant hypertension.

A patient with malignant hypertension due to the simultaneous occurrence of pheochromocytoma and renal artery occlusion is described. The pheochromocytoma was resected, but hypertension persisted postoperatively and significant renovascular disease was observed. The blood pressure returned to normal after nephrectomy. The possible pathogenetic link between the two conditions is discussed, and a therapeutic approach is suggested.

Study of 90 hepatitis B surface antigen carriers in Israel.

A study of 90 asymptomatic hepatitis B surface antigen (HBsAg) carriers in Jerusalem showed a predominance of males over females (4:1) and of North African Jews over Jews of European or American Origin. The predominance of males remained apparent, but was not significant, when origin was controlled. Possible sources of infection were contact with jaundiced patients (29%), dental treatment (58%) and drug addiction (8%). Fifty-one percent had hepatitis B core antibody (anti-HBc) of the IgM class, 2% had hepatitis B e-antigen (HBeAg), 94% hepatitis B e-antibody (anti-HBe) and 93% had hepatitis A antibody (anti-HAV). Fourty-two percent had donated blood at least once prior to the detection of the carrier state. Fifty-five percent of 128 asymptomatic family contacts had evidence of hepatitis B virus infection. Minor abnormalities in liver function tests were found in 22% of the carriers and splenomegaly in 11%. Of ten liver biopsies performed in these cases, one had chronic active hepatitis, five had minimal histological changes, and four were normal.

Hospital admissions due to adverse drug reactions: a comparative study from Jerusalem and Berlin.

A comparative study of adverse drug reactions (ADR) leading to hostpial admission showed that 103 (4.1%) out of 2499 medical admissions in Jerusalem and 167 (5.7%) out of 2933 admissions in Berlin were due to such reactions. Sex distribution in the two patient--populations was almost equal but the Jerusalem patients were younger. The most frequent ADRs were digitalis intoxication (in Berlin) and reactions to antibiotics (in Jerusalem). Other important differences were noted in the relative frequencies of ADRs associated anticoagulants, hypoglycemic agents and oral contraceptives. They were probably related to differences in drug usage in the two countries. The most common major side effects were arrhythmias, allergic reactions, bleeding, congestive heart failure, bronchospasm and hypoglycemia. The following risk factors were identified in both cities: old age, female sex, impaired renal function, previous history of ADR and polypragmasia.

Effect of colchicine on polymorphonuclear leucocyte chemotaxis in human volunteers.

1 The effect of colchicine on polymorphonuclear leucocyte chemotaxis was assessed in eight healthy volunteers. Four of them received 1.0 mg colchicine and the other four received placebo daily for 8 successive days. 2 Chemotaxis decreased significantly within 24 h of the ingestion of colchicine; the values remained low throughout the 8 days of treatment and returned to normal within 48 h of cessation of medication. 3 There were no significant changes in the placebo treated subjects.

Gout and amyloidosis.

Two patients with gout and amyloidosis are reported. In contrast with other forms of chronic arthritis gout is apparently not associated with an increased incidence of amyloidosis. The possible reasons for this exception are discussed.

Left ventricular function in liver cirrhosis: an echocardiographic study.

Left ventricular (LV) size and function were studied by echocardiography and measurement of systolic time intervals in 14 patients with liver cirrhosis. There was a small increase in LV end-diastolic dimension, and an increase in systolic ventricular performance, calculated stroke dimension and stroke and cardiac indices. Mean blood pressure was low normal. Preejection period was shortened and the preejection period/LV ejection time ratio, decreased. The data indicate that patients with liver cirrhosis have mild LV enlargment, reduced peripheral resistance and an increase in mesurements of systolic LV performance.

Sodium transport in red cells of patients with acute viral hepatitis.

The red blood cell composition was determined in 25 patients with acute viral hepatitis and in 26 normal subjects. The potassium concentration was 83.4 +/- 4.11 mmol/kg red cells (mean +/- SD) in hepatitis red blood cells and 79.7 +/- 4.74 mmol/kg red cells in the control samples (P < 0.005). There were no significant differences between the sodium content of normal and hepatitis red blood cells. 22Na-Efflux was determined in red blood cells of 17 patients with acute viral hepatitis and 18 normal subjects. The mean sodium efflux rate constant was 0.212 +/- 0.036 in red cells of patients with hepatitis and 0.295 +/- 0.046 in the control samples (P < 0.001). This difference resulted from a reduction in both the active and residual portions of the red blood cell sodium pump in the patients with viral hepatitis. Red blood cells of patients with acute viral hepatitis accumulated sodium at a significantly slower rate than normal red blood cells. The increase in osmotic fragility after 24 hr incubation at 37 degrees C in the absence of glucose was less prominent in hepatitis red blood cells than in normals. The findings of a reduced sodium efflux and slower accumulation of sodium during incubation, suggest that red blood cells from patients with viral hepatitis are less permeable to sodium, thereby leading to a new steady-state, characterized by a reduced sodium efflux.
