Seasonal variation in systemic onset juvenile rheumatoid arthritis in Israel.

OBJECTIVE: To determine whether there is a seasonal peak onset of systemic juvenile rheumatoid arthritis (SOJRA) suggestive of an infectious etiology. We examined the seasonal variability of SOJRA in Israel. METHODS: A multicenter retrospective chart review of 59 patients with SOJRA, enrolled from 10 rheumatology units or pediatric departments in Israel. All patients met defined criteria of SOJRA. RESULTS: Fifty-nine patients (31 female, 28 male) were followed from 1982 to 1997. Their mean age was 7.1 +/- 4.3 years (range 0.9-16). Forty-six were Jewish and 13 were Arabs or of Bedouin origin. Eighteen patients (31%) had disease onset in the winter, 16 (27%) in the spring, 12 (20%) in the summer, and 13 (22%) in the fall. Twenty-eight patients had a monophasic disease subtype, while 31 had a chronic or cyclic subtype. The seasonal onset in the patients with the monophasic type versus the chronic or the cyclic type shows 7 versus 11 in the winter, 7 versus 9 in spring, 8 versus 4 in summer, and 6 versus 7 in fall, respectively. CONCLUSION: There is no seasonal pattern to SOJRA disease onset in Israel. However, the disease onset of patients having the chronic or the polycyclic subtype tends to be more common in winter and spring. Since patients with this type have more severe disease, it is possible that another specific infectious agent is one of the factors involved in the pathogenesis of the disease. Larger sampling and multicenter studies are required to clarify this point.

Poststreptococcal uveitis.

PURPOSE: To report that uveitis may be a manifestation of poststreptococcal syndrome. METHODS: Case report. Documented attacks of bilateral uveitis were clearly associated with streptococcal infection. RESULTS: Group A streptococcal infection was evident in all bilateral uveitis attacks, which were treated with local or systemic corticosteroids and penicillin. The frequency and severity of the attacks were reduced by penicillin prophylaxis and tonsillectomy. CONCLUSIONS: Uveitis should be included as a possible manifestation of poststreptococcal syndrome. If coexisting streptococcal infection is demonstrated, penicillin prophylaxis should be considered.

Sulphasalazine in the treatment of pauciarticular-onset juvenile chronic arthritis.

Sulphasalazine in a dose of 50 mg/kg/day was administered to ten patients with pauciarticular-onset juvenile chronic arthritis (JCA), with active disease not adequately controlled by nonsteroidal anti-inflammatory drugs (NSAID). The treatment was initiated with 1/4 of this dose and increased by weekly increments of 250-500 mg until the total dose was reached. In all patients sulphasalazine was the first disease-modifying agent tried. Among nine of the ten patients there was significant improvement in all clinical scores, including the number of active joints and the severity grading (tenderness and limitation of motion). Within 3 months of sulphasalazine therapy the laboratory measurements revealed marked improvement in the erythrocyte sedimentation rate (ESR) and haemoglobin values. One patient, in whom the ESR and haemoglobin were normal at onset, had no change in clinical scores. Transient skin rash and elevated liver enzyme levels developed in one patient. These preliminary data suggest that sulphasalazine is an effective and safe second-line agent in the management of pauciarticular-onset JCA. More trials with this drug are needed, including double blind, to study efficacy and safety of sulphasalazine in JCA.

[Poststreptococcal reactive arthritis].

Reactive arthritis is defined as arthritis of 1 or more joints, in association with infection at a distant site, but without the infective agent being found in the synovial fluid. Patients with Group A beta-hemolytic streptococcal infection and articular disease, who do not fulfill the modified Jones criteria for diagnosis of acute rheumatic fever, have been classified as having poststreptococcal reactive arthritis. We describe 6 patients seen during the winter of 1991 who had various clinical presentations of poststreptococcal reactive arthritis. This condition is considered by some as a distinct disease, but by others as part of the spectrum of acute rheumatic fever.

HLA and complement C4 antigens in polyarticular onset seronegative juvenile chronic arthritis: association of early onset with HLA-DRw8.

HLA-A,B,C,DR and DQ antigens were tested in 53 British Caucasian patients with polyarticular onset seronegative juvenile chronic arthritis (JCA); C4 allotypes were also tested in 46. A strong association with HLA-DRw8 was found (RR = 6.1, Fp = 7.6 x 10(-5)), with increased -B5(51) and C4A QO, and decreased -DR7 frequencies. DRw8 incidence correlated with an onset under 5 years, 9 of 12 DRw8+ cases being in this subgroup (Fp = less than 0.06), whereas B5 and C4A QO were prevalent in late onset (greater than or equal to 5 years). Erosions after 5 years associated with HLA-DRw6, and their absence with -Cw1 and -DR5. Genetic susceptibility factors and a further subdivision by onset age are thus demonstrated in this disease. Comparative data suggest that the genetic basis of susceptibility to early onset disease is similar to that of pauciarticular JCA.

Hepatic, cutaneous and hematologic manifestations in juvenile chronic arthritis.

Two patients suffering from systemic onset juvenile chronic arthritis (JCA) with a polyarticular course developed an acute illness shortly after commencing a new second line drug (gold and penicillamine). The clinical picture consisted of fever, rash, lymphadenopathy and hepatomegaly with elevated liver enzymes and hematological changes. The possible relationship of the disease to second line drugs is discussed.

Juvenile Behçet's disease in Israel. The Pediatric Rheumatology Study Group of Israel.

OBJECTIVE: Behçet's disease (BD) is a vasculitis mainly observed in young adult males. Juvenile BD is rare and only small series of pediatric cases have been reported. The objective of this study was to define the epidemiology and clinical features of BD among Israeli children. METHODS: A questionnaire was sent to 8 pediatric rheumatology units in Israel and 30 cases of BD diagnosed before the age of 16 years were identified. RESULTS: Fifteen patients fulfilled the International Study Group Criteria for BD, while 15 had an incomplete form of BD. Among the patients with complete BD, stomatitis and skin involvement were the most common manifestations. Other symptoms included genital ulcers, uveitis, CNS involvement, arthritis, and gastrointestinal involvement. A positive family history was elicited in 3 patients. HLA B5 was found in 7 of 12 patients (58%). The 15 patients with incomplete BD all had recurrent stomatitis; other manifestations included uveitis, arthritis, and genital ulcers. HLA B5 was found in 94% of this group. CONCLUSION: Juvenile BD in Israel is not uncommon, and is frequently associated with HLA B5 positivity. This could indicate a genetic susceptibility in our region. Half of the patients in our series had an incomplete form of BD, which may represent a less severe variant of the disease. In any case, careful follow-up is required, since their condition could eventually evolve into complete BD.
