Antinucleosome antibodies in patients with juvenile systemic lupus erythematosus.

Our objective was to evaluate the frequency of antinucleosome antibodies (anti-Ncs) in juvenile systemic lupus erythematosus (JSLE) comparing it to that observed for anti-DNA and to correlate the presence of these antibodies with clinical manifestations and disease activity. Anti-Ncs and anti-DNA were detected by ELISA in 74 patients with JSLE and 64 normal controls. Clinical records were reviewed. Disease activity was assessed by SLEDAI score. Anti-Ncs and anti-DNA showed sensitivity of 52.7% and 54% and specificity of 98.4% and 95.3%, respectively. Disagreement between the two assays was found in 25.7% of the cases: isolated positive Anti-Ncs in nine cases (12.2%) and isolated positive anti-DNA in 10 cases (13.5%). Agreement was found in 74.3%: both positive antibodies in 30 cases and both negative in 25. The presence of anti-Ncs was significantly associated with malar erythema, hemolytic anemia, anti-DNA and low complement levels, but not with renal manifestations. The presence of anti-Ncs was associated with a higher SLEDAI median (P < 0.001) and its titers correlated with the SLEDAI score (r = 0.504; P < 0.001). The frequency, sensitivity and specificity values were similar between anti-Ncs and anti-DNA antibodies in patients with JSLE. Nevertheless, the discordance of 25.7% between the two assays suggests that both antibodies may have a complementary diagnostic role. The association and correlation between anti-Ncs and several disease activity parameters demonstrated its usufulness in the follow-up of these patients.

[Quality of life evaluation in children and adolescents with chronic and/or incapacitating diseases: a Brazilian study].

OBJECTIVE: To evaluate quality of life in children and adolescents with acute lymphocytic leukemia (ALL) and juvenile rheumatoid arthritis (JRA). MATERIAL AND METHODS: We administered the Children's Global Assessment Scale (CGAS), the Vineland Adaptative Behavior Scale (VABS) and the Autoquestionnaire qualité de vie enfant imagé (AUQEI) to a sample of 28 children with ALL, 28 children with JRA, and 28 healthy controls, aged 4 to 13 years old, who were diagnosed between 1 and 5 years previously. RESULTS: Slight differences were found in age between patients with ALL and those with JRA. No significant differences were found in time since diagnosis or in CGAS scores. A significant difference was found in VABS global scores, as well as in VABS communication domain scores. No significant differences were found in VABS daily living skills domain scores between patients with ARJ and healthy controls. No significant differences were found among the groups in VABS socialization domain scores or in AUQEI scores. CONCLUSION: In our study, chronically ill children clearly performed worse in adaptative behavior development. Nevertheless, their quality of life was similar to that of healthy controls. Appropriate methods to identify pediatric patients' perception of their illnesses and treatment should be urgently developed.

[Takayasu's arteritis].

BACKGROUND: Takayasu's arteritis is a rare vasculitis in the pediatric population that affects the aorta and its branches. There are few studies with an appropriate number of patients and follow-up. OBJECTIVE: To describe the clinical manifestations, laboratory alterations, radiological findings, and treatment in eight children and adolescents with Takayasu's arteritis. METHODS: A retrospective analysis of patients' records from 1990 to 2001 was performed. RESULTS: There were six girls and two boys. The mean age at disease onset was five years and five months. The most common clinical manifestations were systemic findings and cardiovascular, dermatological and neurological abnormalities. In all patients inflammatory activity was high and in three patients the Mantoux test was strongly positive. The most common radiological findings were type IV and V. Treatment included steroids, methotrexate, cyclophosphamide, intravenous gamma globulin, and vascular surgery. Three patients presented sequelae. CONCLUSIONS: Takayasu's arteritis produces considerable morbidity and mortality. To make an early diagnosis, pediatricians should be aware of inflammatory systemic manifestations and cardiovascular abnormalities. To gain further knowledge of this entity prospective and ideally multicenter studies are required.

Gonadal function in adolescents and young women with juvenile systemic lupus erythematosus.

The authors analysed the gonadal function and age of menarche of 23 female adolescents and young women with SLE, and correlated these with clinical, SLEDAI and therapeutic parameters. The presence of one or more clinical and laboratory parameters defined normal gonadal function: normal menstrual cycles with or without dysmenorrhea; elevated cervical mucus length; normal levels of plasma FSH, LH, estradiol, progesterone, prolactin and testosterone; normal urinary hormonal cytology; serial pelvic ultrasound compatible with ovulatory pattern; and present or previous pregnancy. The mean age of menarche (13.5 +/- 1.4 years) was greater than that found among 2578 healthy Brazilian adolescents (12.5 +/- 1.3 years; P = 0.0002). The delay in menarche correlated with an increase in the duration of the disease (P = 0.0085) and the cumulative dose of prednisone (P = 0.0013) used until the appearance of the menarche. The mean phase length in SLE was 31.5 +/- 10.3. Sixteen female (70%) patients showed normal and seven (30%) abnormal gonadal function. Gonadal function was not correlated with parameters of SLE. These results suggest that the patients of this study reach adulthood with a high chance of fertility.
