The variability of the serum binding of the short-acting narcotic analgesic alfentanil was studied. Binding of alfentanil was measured in human alpha 1-acid glycoprotein (AAG) and human albumin solutions, and in serum from 6 groups of individuals: control subjects, patients with renal failure, cirrhosis, rheumatoid arthritis and myocardial infarction, and intensive care patients. Alfentanil is mainly bound to AAG and the influence of a change of the AAG concentration on its binding is much more marked than that of a change of the albumin concentration. In patients with renal failure, myocardial infarction and rheumatoid arthritis and in intensive care patients, AAG concentrations are increased, but alfentanil binding is significantly increased only in patients with myocardial infarction. In patients with cirrhosis, AAG, albumin concentrations, and alfentanil binding are decreased. In vitro addition of lidocaine, disopyramide, bupivacaine and quinidine, in concentrations that are observed clinically, lead only with disopyramide to an important increase in free fraction of alfentanil (from 7 to 19%). This latter finding was confirmed in 2 volunteers, treated chronically with disopyramide.

Plasma concentrations of the recently isolated potent vasoconstrictory peptide endothelin were measured in 382 patients. The investigations were performed by means of a sensitive radioimmunoassay specific for Endothelin-1, 2. The results from 110 healthy volunteers displayed a normal range of 44.67 +/- 3.51 pg/ml. Significantly raised levels were found in 33 patients with chronic end-stage renal failure both before and after hemodialysis. In contrast, 35 patients with compensated renal insufficiency did not differ from the normals. Sixty-five patients after kidney transplantation revealed significantly elevated levels, as did 27 patients with acute myocardial infarction, 8 after coronary bypass surgery, and 5 with liver cirrhosis. The mean values of 27 patients with untreated hypertension, 22 with secondary hypertension, of various causes and 16 with coronary artery disease were comparable to the normal population. The values were significantly decreased in 9 pregnant women with hypertension and proteinuria. A marked decline was found in 5 patients with systemic lupus erythematodes, while 20 patients with rheumatoid arthritis demonstrated only a slight decrease. The pathophysiological role of endothelin as a local or circulating hormone in regulating systemic blood pressure or release of other hormones remains to be determined.

Binding of drugs can vary considerably. Therefore, binding of the calcium antagonist diltiazem was studied in protein solutions and in serum of healthy persons, patients with renal failure, patients with cirrhosis, patients with rheumatoid arthritis, patients with myocardial infarction, and intensive care patients. The effect of in vitro addition of some cardiovascular drugs (lidocaine, disopyramide, quinidine, and bupivacaine) on the binding of diltiazem in serum of healthy volunteers was also investigated. Diltiazem is bound as well to alpha 1-acid glycoprotein (AAG) as to albumin. In patients with renal failure, myocardial infarction, and rheumatoid arthritis and in intensive care patients, AAG concentrations are increased, and in the patients with myocardial infarction an increased binding of diltiazem is found. In patients with cirrhosis, AAG concentrations and diltiazem binding are decreased. In vitro addition of lidocaine, disopyramide, bupivacaine, or quinidine in concentrations between 5 and 100 micrograms/mL, before dialysis, decreases the binding of diltiazem; the displacing effect is most pronounced with bupivacaine.

The liver histology of 52 patients treated with intermittent low dose pulse methotrexate for rheumatoid arthritis was evaluated using a modification of the Roenigk grading system. Patients studied had had an average of 3.2 years of treatment or had received 1.7 g methotrexate. No patient had cirrhosis; 15 (29%) patients had evidence of mild fibrosis. Histological abnormalities were not predicted by liver function test changes, with the exception that hypoalbuminaemia occurred in 60% of those with grade IV (modified criteria) findings. The need for liver biopsy in patients with rheumatoid arthritis treated with methotrexate before two years or 1500 mg of treatment has not been established. Whether serial liver biopsies will be needed beyond this time has yet to be determined.

Radioimmunoassay and enzyme-immunoassay were used to study the detection rates of HBsAg and anti-Delta in blood donors and subjects at high risk of infection with hepatitis B (HB) in the Byelorussian SSR. The republic was found to belong to the region with a moderate prevalence of HB and low prevalence of delta-virus infection. The detection rate of anti-delta antibodies in individual population groups depends on the level of HBsAg carrier state and is closely associated with prolonged treatment in medical institutions. Patients with tuberculosis, rheumatoid arthritis, diabetes mellitus, and cirrhosis of the liver are important reservoirs of HB and delta-virus infection for a region with moderate prevalence of HB virus and low prevalence of delta-virus. Infection with delta-virus is very important in unfavourable outcomes of acute and chronic viral hepatitides in the region.

Red lunulae are associated with rheumatoid arthritis, systemic lupus erythematosus, alopecia areata, cardiac failure, hepatic cirrhosis, lymphogranuloma venereum, psoriasis, carbon monoxide poisoning, twenty-nail dystrophy, and reticulosarcoma. We examined four patients with red lunulae. Three had chronic obstructive pulmonary disease. Two of these three were alcohol abusers and were without any of the conditions previously associated with red lunulae. Two of the four also had palmar erythema. Histopathologic examination of the red lunula in one of the four cases did not show signs of neovascularization. We report our findings in these patients, which suggest that red lunulae result from increased arteriolar blood flow, a vasodilatory capacitance phenomenon, or changes in the optical properties of the overlying nail so that normal blood vessels become more apparent.

Methotrexate is an effective agent for the treatment of rheumatoid arthritis. It is now widely prescribed for patients who have not tolerated or responded to gold compounds or penicillamine. Minor adverse reactions are common, and fatal pulmonary toxicity or cirrhosis can occur. The drug does not produce disease remissions, but continued administration helps reduce pain, stiffness and swelling. Within the past year, the Food and Drug Administration has approved methotrexate for use in treating rheumatoid arthritis.

A group of 40 subjects (33 women and 7 men) assembled in the course of several years comprised clinical and ambulatory patients. The main characteristic of the group was isolated seropositivity of rheumatoid factors assessed by the latex fixation test with titres of 1:320 and more in apparently healthy subjects. The mean age of the subjects at the beginning of the investigation was 39 years. They were followed up for 2-18 years, on average for 7.8 years. Regular clinical, biochemical and immunological check-up examinations were made after 1-2 year intervals. The latex fixation test was made in a test tube. The most serious manifestation was the development of rheumatoid arthritis in 7 subjects (6 women and 1 man). In two of them it was preceded by palindromic rheumatism. Two women have abortive manifestations of systemic lupus erythematosus. Seven developed, mostly repeatedly, tendovaginitis in the region of the flexors of the fingers and abductors of the thumb. Seven subjects suffered from polyarthritis of the hands. None of the subjects suffered from cirrhosis or monoclonal gammapathy. In the course of the investigation the titres of rheumatoid factors had a declining trend even to negative values. In 23 they became negative or had titres of 1:40. The high incidence of rheumatoid arthritis in 17% apparently healthy subjects with isolated seropositivity of rheumatoid factors emphasizes the importance of dispensarization of these subjects in a rheumatological surgery and of careful long-term follow up. Early administration of line 2 antirheumatic drugs could prevent a possible fatal course of rheumatoid arthritis.

Part of the hyaluronic acid (HA) synthesized in peripheral tissues enters the blood circulation through the lymph. It is rapidly taken up by the endothelial cells in the liver (half-life in blood is 2.5-5.5 minutes) and degraded. Pure primary cultures of liver endothelial cells were obtained by a newly developed technique and used to follow the metabolism of the polysaccharide on the cell surface. At 37 degrees C the HA is effectively endocytosed and degraded to acetate and lactate. A radioassay specific for HA and sensitive in the nanogram range has been developed to follow the concentration of HA in serum. The normal level in man is 10 to 100 micrograms/l. Elevated serum levels of HA are seen in liver cirrhosis, rheumatoid arthritis and scleroderma indicating that both an impaired catabolism in the liver and an increased synthesis in the peripheral tissues can modify the HA level.

Methotrexate-induced hepatotoxicity is well recognised in the treatment of leukaemia, psoriasis and rheumatoid arthritis. The pathological lesions are non-specific, consisting of fatty change, nuclear pleomorphism, hepatocyte necrosis, portal chronic inflammatory infiltrate, fibrosis and cirrhosis. The mechanism of liver injury is poorly understood; intracellular accumulation of methotrexate polyglutamate and consequent folate depletion are suspected to play a role. Early studies in psoriasis clearly established a relationship of the hepatic injury with the frequency of methotrexate administration. With weekly low dose therapy, however, consensus is lacking regarding the incidence of hepatotoxicity because studies have had disparate control groups, used variable dosage regimens and often failed to document pre-existing liver disease or categorised patients at risk, i.e. elderly patients, alcoholics and obese diabetics. Moreover, current methods of assessing the degree of hepatic injury are subjective, relying on interpretation by an experienced histopathologist. Preliminary evidence suggests less frequent and less severe hepatotoxicity occurs in patients with rheumatoid arthritis, probably as a result of lower methotrexate doses and better patient selection. Nevertheless, until the risk of serious liver disease is better defined it is recommended that patients have a pretreatment liver biopsy, a follow-up biopsy after a cumulative dose of 1500 mg, and then biopsies approximately every 2 years in the absence of other evidence of liver disease or risk factors.
