An association between viral hepatitis and two rheumatic disease syndromes has been observed. Twenty-nine patients manifested a transient polyarthritis, sometimes associated with a rash (Group I). Ten patients were seen with a multisystem disease (Group II). Histologic evidence of arteritis or glomerulonephritis was present in seven of ten patients with multisystem disease. Liver tissue from 18 patients showed morphologic evidence of hepatitis with viral features in 9 of 10 patients in Group I and in 6 of 8 patients in Group II. Hepatitis B surface antigen (HBsAg) and/or antibody to HBsAg were detected in sera of all 39 patients. Abnormal liver functions were present in 36. Twelve Group I patients and 2 Group II patients became jaundiced. Rheumatoid factor was present in sera of seven patients in each group. The third component of complement (C3) was depressed in 13 patients in Group I and 7 patients in Group II. The fourth component of complement (C4) was decreased in 8 of 21 Group I and 3 of 7 Group II patients. Synovial fluid C3 was decreased in 2 of 11 Group I and 1 of 4 Group II patient's fluids. Articular inflammation in patients with transient polyarthritis responded in three to seven days to aspirin, acetominophen and/or bedrest alone and rashes disappeared spontaneously. Patients with multisystem disease generally had a prolonged illness and responded somewhat unpredictably to prednisone or a combination of prednisone and cyclophosphamide.

Agglutinins reacting with normal and tanned sheep erythrocytes were the probable cause of false positive reactions given by 51 of 214 Liberian sera when using a commercial passive-haemagglutination test for hepatitis-B surface antigen. Absorption showed these agglutinins to be identical to those described earlier in Nigerian sera. Rheumatoid factor and anti-sheep-serum antibodies although present in 12 and five per cent respectively of all sera were not responsible for any false positive reactions. The practical conclusion is that such tests, based on sheep erythrocytes are unsuitable for screening this population.

Serological parameters were compared in 15 cases of Coxiella burnetii infection comprising 5 cases each of primary Q fever, chronic granulomatous hepatitis, and endocarditis. The diagnosis was made on the basis of clinical history and serology and on the isolation of C. burnetii phase I from biopsy specimens of liver and bone marrow from two patients with granulomatous hepatitis and from the aortic valve vegetations of five patients with endocarditis. The temporal sequences of immunoglobulin levels, rheumatoid factor, and specific antibody responses to phase II and phase I antigens of C. burnetii were evaluated as predictive correlates of the three Q fever entities. Serum levels of immunoglobulin classes G, M, and A were variable in all the entities of Q fever. Increased mean levels (in milligrams per deciliter) of immunoglobulin G (IgG) and IgA were noted with chronic disease in the sera of some patients, whereas IgM levels were not significantly different from normal values. Rheumatoid factor was significantly elevated in chronic disease but not in primary Q fever. The temporal sequence of C. burnetii phase II and phase I antibodies were compared by microagglutination, complement fixation, and indirect microimmunofluorescence tests. All of these serological tests were useful in distinguishing primary from chronic disease. Thus, the ratio of anti-phase II to anti-phase I antibodies was greater than 1, greater than or equal to 1, and less than or equal to 1 for primary Q fever, granulomatous hepatitis, and Q fever endocarditis, respectively. Moreover, the high phase-specific IgA antibody titers in the indirect microimmunofluorescence test were diagnostic for endocarditis.

Mixed cryoglobulinemia is frequent in southern Europe and attributed to hepatitis C infection. We analyzed prevalence and clinical symptoms of mixed cryoglobulinemia in our region among patients with chronic hepatitis C (n = 29) and B (n = 7) in comparison to alcoholic liver cirrhosis without evidence of hepatitis virus infection (n = 10). Cryoglobulinemia was found in 13/29 patients with hepatitis C (11 type III, one type I1-III and one type II), 2/7 with hepatitis B (one type II, one type III) and 4/10 with alcoholic liver cirrhosis (one type II, three type III). Patients with moderate active hepatitis had more type II than type III cryoglobulins. Concerning clinical symptoms, only sicca syndrome was more frequent in patients with hepatitis C. Rheumatoid factor (RF) and immune globulin M (IgM) levels were higher in hepatitis C than in the other groups. Renal disease was rare in all but not different between the groups. Mixed cryoglobulinemia in hepatitis C (and B) is most frequently of type III. Patients with hepatitis C had the same prevalence of cryoglobulins as patients with alcoholic liver cirrhosis. Cryoglobulins had no influence on clinical syndromes or organ damage.
