The association of serum matrix metalloproteinases and their tissue inhibitor levels with scleroderma disease severity.

OBJECTIVE: Matrix metalloproteinase 3 (MMP-3) is reported to play an important role in the pathogenesis of systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Studies have also investigated the association of different tissue inhibitors of MMPs (TIMPs) with fibrosis in scleroderma (SSc). The aim of this study was to evaluate the correlation of serum MMP-1, 3 and TIMP-1 with severity and disease specific markers of SSc and RA. METHODS: Serum MMP-1,3 and TIMP-1 were measured in 42 SSc patients (age range 28-68 yr mean 47 yr) and compared to 29 RA and 30 healthy age- and sex-matched individuals. Elevated values of MMPs and TIMP-1 were defined as those greater than 2 SD above the normal mean. All SSc and RA patients were scored for disease severity. RESULTS: Serum MMP-1 was significantly elevated in 8/42 (19%) SSc patients (p = 0.01) but only in 2/29 (7%) RA patients (p = 0.2). Whereas MMP-3 levels were elevated in 10/29 (34%) RA patients (p = 0.002), it was elevated in only 5/42 (12%) SSc patients (p = 0.03). TIMP-1 was found elevated in 17/42 (40%) SSc patients (p = 0.001) and in only 4/29 RA patients (with a strong trend towards significance, p = 0.052). We found a significant association between the elevation of both MMPs and TIMP-1 levels, with the severity of SSc. Those who had an increase of more than one MMP and/or TIMP, demonstrated life-threatening major organ involvement such as end stage lung fibrosis, GI aperislasis, and severe cardiacfailure. Contrary to that in SSc, the severity of RA showed some trend of association with MMP-3 only. CONCLUSION: We confirm previous observations that MMPs and TIMPs may play an important role in various rheumatic diseases. Whereas serum increase of MMP-3 correlated with RA severity, SSc severity was more characterized by the increase of both MMP-1 and TIMP-1. This suggests that the MMPs and TIMPs involved in SSc are different than those playing a role in RA, which may indicate that in SSc they are produced in different locations than in RA.

[Efficacy of a non blind placebo prescription].

The aim of our open clinical trial was to determine the efficacy and the tolerance of a blue coloured placebo in moderated anxious patients (Hamilton score below 15) and a red one for tired patients without DSM IV criteria of major depressive disorder. All the patients knew that treatment was a placebo and so, had no pharmacological effect. The trial run over seven days. All patients were considered as responders if their initial symptoms were reduced more than 50%. At the end of the week, the final clinical evaluation showed that 18 patients about 34 were in good condition (10 anxious patients, 7 women and 3 men, and 8 tired patients, 4 women and 4 men). The anxious score of Hamilton scale was reduced of 63%; 16 of the 18 responders were absolutely sure that the treatment was usefull. Four patients were obliged to stop their treatment because side effects: insomnia, tiredness and sleepiness, gastric pain and itching of fore arm.

Severe outcome of juvenile idiopathic arthritis (JIA) associated with familial Mediterranean fever (FMF).

Juvenile Idiopathic Arthritis (JIA) and Familial Mediterranean Fever (FMF) may involve the same population of children and be confused at times. In a cohort of 350 consecutive FMF patients followed by us, 98 had onset before 10 years of age and, of those, JIA was present in 3. All three had the M694 V mutation of the MEFV gene and were of North African ancestry. The prognosis of these 3 was extremely poor: one developed bilateral knee osteonecrosis with total joint replacement, repeated ileal obstruction with small bowel resection, renal failure and sterility due to amyloidosis and osteoporotic fractures and died at 42 years of age; a second developed deforming erosive arthropathy and underwent bilateral total hip replacement; the third developed severe erosive polyarthritis and also underwent bilateral hip replacements. Aggressive treatment is indicated when JIA and FMF coexist.

Pseudopodagra: A presenting manifestation of infective endocarditis.

Podagra is a term used to describe acute monoarthritis of the first metatarsophalangeal (1st MTP) joint. The most common diagnoses of arthritis in this joint are: crystal-induced synovitis, septic arthritis, traumatic conditions and reactive arthritis. When etiologies other than gout are involved this is frequently referred to as pseudopodagra. We report the case of a patient who presented with pain and swelling of the 1st MTP The absence of intraarticular crystals and hyperuricemia encouraged further evaluation of the patient. A cardiac murmur was investigated by echocardiography, which revealed valvular vegetations and the diagnosis of infective endocarditis (IE) was established. This is the first reported case of a podagra-like presentation of IE. As in this case, the diagnosis of gout should rest on findings beyond the presence at 1st MTP arthritis, with evaluation of all extraarticular signs in order to rule out other possible diagnoses.

Behçet's disease, myelodysplastic syndrome, trisomy 8, gastroenterological involvement--an association.

Only a limited number of cases of Behçet's disease and hematological malignancies have been reported in the literature. We report the case of a 45 year old female patient with Behçet's disease who developed myelodysplastic syndrome, refractory anemia with excess blasts in transformation subtype, with complex chromosomal abnormalities, including excess of chromosome 8, following several years of treatment with chlorambucil for Behçet's disease. As has been described in most such cases, gastrointestinal involvement was most prominent. This case is described and the occurrence of myelodysplastic syndrome in Behçet's disease reviewed.

Aortic involvement in rheumatic diseases.

OBJECTIVE: To review the prevalence, mechanisms, presentations and clinical significance of aortic involvement in rheumatic inflammatory diseases. METHODS: The medical literature, available through a PUBMED search was reviewed and the relevant information was summarized. In addition, selected articles related to aortic involvement in rheumatic diseases were included in this review. RESULTS: Rheumatic disorders may be categorized by their propensity to involve the aorta: conditions with a prevalence of 10% and more (Takayasu's arteritis, temporal arteritis, long-standing ankylosing spondylitis, Cogan's syndrome and relapsing polychondritis), disorders with uncommon but well documented aortic involvement and rheumatic conditions with rare case reports of such involvement. Clinical presentation of aortic disease is dependent on the part of aorta involved and may manifest by aortic pain and/or other symptoms caused by aortic dilatation, narrowing or aneurysm. The histopathology of inflammatory aortitis is characterized by lymphoplasmacytic infiltration with or without giant cells or granulomas. On the other hand, non-inflammatory aortic damage in rheumatic diseases may include Marfan-like cystic disintegration of the aortic media as well as accelerated atherosclerosis. Awareness of rheumatic conditions with a high potential for clinically significant aortic involvement may promote referral of such patients for aortic imaging and sometimes surgery before fatal complications intervene. CONCLUSION: Early diagnosis of aortic involvement can be advanced by informed consideration of such a complication in a rheumatic patient.
