[Baker cysts: an accompaniment of chronic diseases of the knee joint (author's transl)].

One hundred and twenty one Baker cysts demonstrated by arthrography have been analysed. Morphologically one must distinguish between distension cysts and dissection cysts. Distension cysts are more common with various diseases of the knee joint (68% of all cysts). Dissection cysts (32%) are found particularly with inflammatory-rheumatic diseases and are rarely of degenerative or post-traumatic origin. Acute rupture of the cyst was observed on ten occasions. Repeated rupture, which had only been suspected previously, was demonstrated by arthrography in four patients. It is pointed out that Baker cysts may imitate the features of acute thrombophlebitis.

Antefemoral dissecting cysts in rheumatoid arthritis.

Five cases of an antefemoral synovial cyst in rheumatoid arthritis were confirmed by arthrography. Communicating with the suprapatellar bursa, these rarely observed cysts may be considered an anterior analogy to dissecting Baker cysts.

[Clinical relevance of circulating immune complexes in patients with systemic lupus erythematosus and chronic polyarthritis].

Using a solid phase C1q assay, circulating immune complexes (IC) were detected in 15 of 55 patients with rheumatoid arthritis (RA) and 6 of 14 patients with systemic lupus erythematosus (SLE). In contrast to RA, presence of IC correlated to clinical disease activity in SLE patients. Preliminary short term follow up studies revealed additional differences between RA and SLE: whereas persistence of IC was noted in the patients with SLE, rapid changes of IC levels were observed in RA.

[Circulating immune complexes in patients with malignant diseases].

Circulating immune complexes were determined by a solid phase C1q assay in patients with divers malignancies. In Hodgkin's disease (n = 20), immune complexes were detected only in two patients during chemotherapy. Both patients succumbed shortly thereafter. In patients with testicular malignancies (n = 18), immune complexes were detected especially in patients without evidence of metastatic disease. Sequential investigations did not reveal prognostic insights. Summing up these data and the data obtained in additional patients with malignancies, it is interesting to note, that patients with carcinomas have a significant higher incidence of circulating immune complexes with malignancies of the lymphatic system. Our data, however, do not exclude presence of other than C1q binding immune complexes.

[New aspects in the pathogenesis of anemia in chronic polyarthritis].

In 44 patients with rheumatoid arthritis and 30 control persons, the activities of the following three hemesynthesizing enzymes were determined: delta-aminolevulinic acid dehydratase (D-ALA-D), porphobilinogen deaminase (PBG-D), and ferrochelatase (FCH). Compared with the control persons in patients with rheumatoid arthritis, statistically significant decreased activities of FCH were determined, whereas no differences between the two groups tested occurred with D-ALA-D and PBG-D.

[Case report of a patient with coexistent rheumatoid arthritis and ankylosing spondylitis].

In simultaneous conditions of inflammatory changes in peripheral joints and in sacroiliac joints, a differential diagnosis, amongst others, of rheumatoid arthritis with involvement of the sacro-iliac joints and also ankylosing spondylitis with peripheral joint involvement should be considered. It seems that in rare cases both diseases occur together. We describe one female patient with coexistence of rheumatoid arthritis and ankylosing spondylitis. The X-rays showed sacro-iliitis, syndesmophytes and inflammatory changes of the finger and toes, which are typical for rheumatoid arthritis. Rheumatoid factor was detected in serum and in synovial fluid. HLA B27 was negative. The results of 13 patients with coexistence of rheumatoid arthritis and ankylosing spondylitis reported in the literature since 1975, are compared with the above described patient.

[Lymphocyte response to mitogens in serum-free and serum-containing medium in patients with rheumatoid arthritis (author's transl)].

Mitogenic transformation of lymphocytes from patients with rheumatoid arthritis (RA) has revealed divergent results in different laboratories. Since the sera used for medium supplementation in these previous studies might have influenced the results, we investigated lymphocyte transformation in serum-free medium in 28 RA-patients and 25 controls. It was shown that a majority of patients with RA responded weakly to PHA. Comparing some of these serum-free cultures with cultures that were set in parallel in 10% ABserum, no difference between patients and controls was observed after transformation in supplemented medium. It is concluded that lymphocyte reactivity to PHA (however not to ConA and PWM) is diminished in patients with RA and that this defect--at least partially--is reversible by addition of serum. The use of parallel cultures in serum-free and serum-containing medium is recommended for evaluation of the lymphocyte mitogenic response.

[Are antinuclear factors a contraindication for penicillamine treatment in patients with rheumatoid arthritis? (author's transl)].

28 patients with rheumatoid arthritis undergoing treatment with penicillamine were investigated over a period of 7 to 72 months. Antinuclear antibodies were detected in 43% of patients before treatment, and 39% when treatment was completed. In all patients anti-native DNA antibodies were within the normal range. Precipitating antibodies to heat-denatured DNA were detected in 3 out of 16 patients at the end of therapy. There was no correlation between the detection of antinuclear antibodies, antibodies to native or denatured DNA and the occurrence of immunological side effects due to penicillamine (1 patient with pemphigus erythematosus, 3 patients with immune-complex nephritis).

HLA-B8 in caucasian patients with systemic lupus erythematosus.

HLA antigen frequencies were determined in 27 Caucasians with systemic lupus erythematosus (SLE). A statistically significant association between HLA-B8 and SLE was found. HLA-B8 occurred in 48% of patients and in 18% of controls (P corr approximately equal to 0.005). The relative risk of SLE for HLA-B8 carriers is 4.23. In addition, SLE patients with later onset of disease more frequently had HLA-A1 and/or HLA-B8. There was no association between any HLA antigen and clinical (renal, central nervous system, and lung involvement) or serological (antinuclear and anti-nDNA antibodies) parameters.

[Systemic lupus erythematosus in twins (author's transl)].

A report is given of systemic lupus erythematosus (SLE) in monozygotic twins. One sister developed coombs-positive haemolytic anaemia at the age of 11 years and suffered from five haemolytic crises over a period of 8 months. SLE could not be proven at that time, but following a 3-year symptom-free period, characteristic clinical and immunological evidence of SLE became manifest. The second sister developed classical SLE at the age of 15 years. Clinical, immunological, etiological and therapeutical aspects of SLE are being discussed.

Antibodies to pancreatic duct cells in Sjögren's syndrome and rheumatoid arthritis.

In the present investigation the occurrence of humoral immunity to pancreatic duct cells (PDC) was studied in 12 patients with Sjögren's syndrome (SS), 31 patients with rheumatoid arthritis (RA), and 64 controls. Four sera of patients with SS and eight of patients with RA produced diffuse cytoplasmic fluorescence of intro- as well as of interlobular PDC of human and rhesus monkey origin. All sera positive with PDC antigens gave also positive staining reaction with parotid, submandibular, and lacrimal duct cells. In absorption studies antibody activity to PDC and salivary duct cells could be absorbed equally well with human or monkey parotid gland or pancreas with almost identical antigen concentrations. These findings point to the presence of common antigenic determinants in the organs studied. Human thyroid microsomes and rat liver homogenate did not reduce antibody activity. The demonstration of antibodies to PDC in addition to the reported mononuclear cell infiltration of the pancreas point to the involvement of autoimmune mechanisms in pathogenesis of the commonly observed subclinical exocrine insufficiency in SS and in some cases of RA.

Seropositive rheumatoid arthritis associated with decreased diffusion capacity of the lung.

Sixty-two patients with classical or definite rheumatoid arthritis were subjected to lung function analysis. The various parameters--spirography, plethysmography, blood gas analysis, measurement of lung compliance, and diffusion capacity--were correlated with duration and stage of disease, and with rheumatoid factor titres. A statistically significant correlation was found to exist between Rose-Waaler titre and specific diffusion capacity. Similar results between Rose-Waaler titre and lung compliance, however, were not statistically significant.
