Efficacy of compression gloves in rheumatoid arthritis.

Twenty-three patients with rheumatoid arthritis whose disease had become stabilized while receiving non-steroidal, anti-inflammatory drugs and/or gold salt injections entered an 8 week crossover study in which the effect of a compression glove worn during sleep was compared to a loosely fitting glove made of the same material. Improvement in hand symptoms was greater with the compression glove than with the control glove as regards morning stiffness, pain, night time throbbing, numbness or heaviness and a subjective assessment of swelling (p = 0.01). In addition, swelling of the proximal interphalangeal joints was slightly reduced (p = 0.05). These data suggest that the night time use of compression gloves in patients with rheumatoid arthritis can improve hand symptoms and exert a mild, transiently beneficial effect upon the degree of hand swelling.

Low molecular weight C1q-precipitins in hypocomplementemic vasculitis-urticaria syndrome: partial purification and characterization as immunoglobulin.

A lupus-like syndrome involving chronic urticaria with cutaneous vasculitis, systemic symptoms, hypocomplementemia with preferential depletion of C1q, and low m.w. (7S) C1q-precipitins has recently been defined. The C1q-precipitin activity (C1q-p) seems to represent a diagnostic marker of the disease, but its chemical nature is not yet clear. We have partially purified and characterized C1q-p from the serum of two patients with this syndrome and compared its activity with the C1q-precipitating activity of aggregated human gamma-globulin (AHGG) anti-C1q antibodies, and several polynucleotides including DNA and polyinosinic acid. C1q-p was found to partition with IgG during precipitation by ammonium sulfate and low ionic strength buffer as well as during column chromatography on DEAE-cellulose and G-200 Sephadex. Like AHGG, but in complete contrast to the polynucleotides, the C1q-precipitating activity of C1q-p was sensitive to pepsin, trypsin, and acidic conditions, but unaffected by DNAse or RNAse; the C1q-precipitating activity of anti-C1q antibody was not diminished by any of these procedures. Thus, C1q-p consists of gamma-migrating protein of low m.w., and its C1q-precipitating activity is indistinguishable from that of AHGG. These results are consistent with the concept that C1q-p is comprised, at least in part, of IgG that binds C1q via the Fc portion of the molecule.

Gastrointestinal blood loss. Effect of aspirin, fenoprofen, and acetaminophen in rheumatoid arthritis as determined by sequential gastroscopy and radioactive fecal markers.

The feasibility of determining the exact site and amount of drug-induced gastric bleeding was tested. Fourteen patients with rheumatoid arthritis received equivalent therapeutic doses of the antinflammatory drugs aspirin, 4 gm/day, and fenoprofen calcium, 2.4 gm/day, in randomized order for seven days. Acetaminophen was given for 14 days just prior to each of these periods. By fiberoptic gastroscopy, antral ulceration and acute mucosal lesions were found in seven patients following aspirin ingestion, in one taking fenoprofen, and in none taking acetaminophen. Fecal blood loss in four-day stool collections, quantitated by autologous chromium 51-labeled erythrocytes shed into the stool averaged 5.0 ml/day while taking aspirin, 2.2 ml/day while taking fenoprofen calcium, and 0.8 ml/day while taking acetaminophen. The mean blood loss was greater for those in whom gastric lesions developed while taking aspirin than for those in whom lesions did not develop. The short-term risk of erosive gastritis was greater for aspirin than fenoprofen.

Alpha1-antitrypsin deficiency with severe panniculitis. Report of two cases.

Two patients with profound decrease of alpha1-antitrypsin (PiZZ) presented with severe pannicultis (Weber-Christian disease); one had systemic panniculitis including pancreatitis. Another possible case is quoted from the literature. Although milder forms of panniculitis can have normal Pi phenotypes and alpha1-antitrypsin levels, the marked reduction of antiproteolytic activity found in PiZZ homozygotes may predispose to or aggravate the lesions of Weber-Christian disease.

Double-blind, multi-centre parallel trial of ketoprofen and ibuprofen in the treatment of rheumatoid arthritis.

A double-blind parallel multi-centre study of 102 patients with rheumatoid arthritis (RA) was performed, comparing ibuprofen (1200-2400 mg daily) and ketoprofen (150-300 mg daily) a new non-steroidal, anti-inflammatory agent, over a three month period. Ketoprofen was well tolerated and shown to have comparable efficacy with ibuprofen. Longterm efficacy and tolerance studies are indicated.

Hemarthrosis associated with sodium warfarin.

Three patients developed an acute hemarthrosis related to sodium warfarin. Synovial aspiration was well tolerated and necessary to substantiate the diagnosis. Prior joint disease was present in two but in only one was there a definite precipitating event, namely minor trauma. The prothrombin time was within the therapeutic range in two of the three. The acute synovitis subsided after the warfarin was discontinued. Joint function seems to have fully returned but long-term evaluation is needed.

Association of antibodies to ribonucleoprotein and Sm antigens with mixed connective-tissue disease, systematic lupus erythematosus and other rheumatic diseases.

Extractable nuclear antigen contains ribo-nuclease-sensitive (ribonucleoprotein) and ribonuclease-resistant (Sm) components. To determine the diagnostic usefulness of antibodies to these antigens, a multicenter study was undertaken in which serums were analyzed for these antibodies and the findings compared with clinical and other laboratory characteristics of the patients. Of 100 patients with hemagglutinating antibodies to ribonuclease-sensitive extractable nuclear antigen, and only the same antibodies by immunodiffusion, 74 per cent had typical features of mixed connective-tissue disease; 12 features of systemic lupus erythematosus, eight those of scleroderma and six an undifferentiated mild connective-tissue disease. Of 27 patients with hemagglutinating antibodies to ribonuclease-resistant extractable nuclear antigen (and Sm antibodies by immunodiffusion), 85 per cent had typical systemic lupus. Thus, antibodies to nuclear ribonucleoprotein and Sm are of diagnostic use; if the serum contains only ribonucleoprotein antibody in high titer, it is likely that the patient has mixed connective-tissue disease.

Increased risk for spondylitis stigmata in apparently healthy HL-AW27 men.

Evidence for ankylosing spondylitis was sought by clinical, radiologic, and ophthalmologic examination in HL-A W27-positive men, aged 18 or older, selected from a tissue-donor population. Back pain of 3 months' duration or longer (P less than 0.05), back stiffness, restricted lumbar flexion and chest expansion, sacroiliac erosions (P less than 0.05) and sclerosis, and ophthalmologic sequels of anterior uveitis were found more often in the 24 men of the W27 group than in a control group of 31 men lacking this antigen. Based upon accepted criteria, 3 W27 persons had definite spondylitis and an additional 3 W27 persons and one control subject had findings strongly suggestive of spondylitis (P less than 0.05). This striking frequency, if extrapolated to the general population, would place approximately 1 of 4 W27-positive men at risk for this disease.

Ibuprofen or aspirin in rheumatoid arthritis therapy.

Ibuprofen is a nonsteroidal drug with analgesic, antipyretic, and anti-inflammatory properties that was recently introduced for use in antiarthritis therapy in the United States. In a year-long double-blind multiclinic trial in 885 patients with rheumatoid arthritis, ibuprofen was at least as satisfactory as aspirin, considering both efficacy and tolerance. In the majority of patients, daily doses ranged from 800 to 1,600 mg of ibuprofen and 3 to 6 gm of aspirin. The drugs did not differ greatly in providing relief from arthritis symptoms, but ibuprofen was definitely better tolerated, especially in regard to gastrointestinal complaints. Seven percent of the ibuprofen group dropped out of the study because of adverse reactions, as compared with 16% of the aspirin group; 17% of the ibuprofen group and 31% of the aspirin group had gastrointestinal symptoms.

Arterial thrombosis in scleroderma.

Clinical and pathological observations are presented on five patients with scleroderma who developed thrombosis of a major vessel. Three died following intestinal infarction or limb gangrene and two had digit or extremity amputation. Severe intimal thickening of major arteries with thrombus formation was noted but no significant abnormality was found in the clotting activity of the blood. Histochemical studies in three cases suggested a reduction of fibrinolytic activity at the site of thrombosis in the diseased vessels. These studies support the view that the vascular system is profoundly altered in scleroderma and may play an important role in some manifestations of the disease.
