Growth hormone treatment in children with rheumatic disease, corticosteroid induced growth retardation, and osteopenia.

BACKGROUND: In children with severe rheumatic disease (RD), treatment with corticosteroids (CS) is frequently needed and growth retardation and osteopenia may develop. A beneficial effect of human growth hormone (hGH) has been reported but mostly in trials without a control group. AIMS: To study the effect of hGH on growth, bone mineral density (BMD), and body composition, taking the disease activity and CS use into account. METHODS: Randomised controlled trial on 17 prepubertal RD patients with growth retardation and/or decreased BMD. The hGH group (n = 10) received treatment with hGH 4 IU/m2/day (approximately 0.045 mg/kg/day) during two years. The controls (n = 7) received no GH treatment. RESULTS: During the two year study period the disease activity, and use of CS and methotrexate (MTX) did not differ between the groups. There was a significant mean increase in height standard deviation score (HSDS) in the hGH group (0.42+/-0.16 SDS) and a non-significant decrease in the controls (-0.18+/-0.11 SDS). Change in BMD did not differ significantly between the groups, although the increase in BMD for lumbar spine within the hGH group was significant. Lean body mass improved significantly in the hGH group compared to controls (0.64+/-0.19 SDS versus -0.20+/-0.17 SDS), while the decrease in percentage fat was not significant. CONCLUSIONS: There was a significant effect of hGH on growth and lean body mass, but a longer duration of treatment might be necessary to evaluate the effect of hGH on BMD.

Autologous stem cell transplantation for refractory juvenile idiopathic arthritis: analysis of clinical effects, mortality, and transplant related morbidity.

OBJECTIVE: To evaluate the safety and efficacy of autologous stem cell transplantation (ASCT) for refractory juvenile idiopathic arthritis (JIA). DESIGN: Retrospective analysis of follow up data on 34 children with JIA who were treated with ASCT in nine different European transplant centres. Rheumatological evaluation employed a modified set of core criteria. Immunological reconstitution and infectious complications were monitored at three month intervals after transplantation. RESULTS: Clinical follow up ranged from 12 to 60 months. Eighteen of the 34 patients (53%) with a follow up of 12 to 60 months achieved complete drug-free remission. Seven of these patients had previously failed treatment with anti-TNF. Six of the 34 patients (18%) showed a partial response (ranging from 30% to 70% improvement) and seven (21%) were resistant to ASCT. Infectious complications were common. There were three cases of transplant related mortality (9%) and two of disease related mortality (6%). CONCLUSIONS: ASCT in severely ill patients with JIA induces a drug-free remission of the disease and a profound increase in general wellbeing in a substantial proportion of patients, but the procedure carries a significant mortality risk. The following adjustments are proposed for future protocols: (1) elimination of total body irradiation from the conditioning regimen; (2) prophylactic administration of antiviral drugs and intravenous immunoglobulins until there is a normal CD4+ T cell count.

Female sex hormones at the onset of systemic lupus erythematosus affect survival.

Female sex hormones affect susceptibility to systemic lupus erythematosus (SLE). To determine the effect of female sex hormones at onset of SLE on the survival of these patients, a retrospective survey was performed. The charts of 168 female SLE patients were evaluated to study the disease course, in particular the presence and kind of SLE criteria. Patients were classified as either belonging to the 'high female sex hormone at onset (HH)' or 'low female sex hormone at onset (LH)' group according to age at diagnosis. The statistics of the Dutch population, matched for age, were used to control for differences in life expectancy in these groups. A Cox regression model revealed that the relative mortality risk of HH patients vs HH controls was 4.2 times higher than the relative mortality risk of LH patients compared to LH controls. No differences in the frequency of SLE criteria between HH and LH patients were found that could explain the observed difference in mortality risk.

The Dutch version of the Childhood Health Assessment Questionnaire (CHAQ) and the Child Health Questionnaire (CHQ).

We report herein the results of the cross-cultural adaptation and validation into the Dutch language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Dutch CHAQ was fully validated with 3 forward and 3 backward translations while the CHQ was already published and therefore it was revalidated. A total of 180 subjects were enrolled: 100 patients with JIA (17% systemic onset, 31% polyarticular onset, 18% extended oligoarticular subtype, and 34% persistent oligoarticular subtype) and 80 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Dutch version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA.
