Age of onset as a risk factor of renal involvement in Henoch-Schönlein purpura

Background Henoch-Schönlein purpura (HSP) is the most common vasculitis in children, characterized by triad of symptoms; palpable purpura without thrombocytopenia, abdominal pain, and arthritis. Renal involvement often occur in children with HSP. No data on the renal involvement of children with HSP in Indonesia, especially West Java. Objective To evaluate renal involvement in children with HSP. Methods Retrospective study was conducted in children with HSP in Department of Child Health, Hasan Sadikin Hospital, from 2006 to 2011. Characteristics and clinical manifestations was reviewed from medical record. HSP was diagnosed by American College of Rheumatology 1990 criteria or European League Against Rheumatism/Pediatric Rheumatology International Trials Organization/Pediatric Rheumatology European Society 2008. Results There were 128 patients, consisting of 82 male (64.9%) and 46 female (35.1%) with ratio 1.8:1. Mean age was 7.9 ± 2.9 years old which range from 6 month to 15 years. Peak morbidity was between 5-10 years old. Prevalence of HSP in Hasan Sadikin Hospital tend to raise from 2.7/100,000 in 2008 to 5.2/100,000 in 2010. In most patients (71%) purpura was the first symptom. Seventy-one patients (44.5%) had arthritis and 89 patients (69.5%) had abdominal pain, while renal involvement was in 28 patients (21.8%). Gastrointestinal manifestations tend to manifest in patients less than 5 years old (p = 0.267), while renal involvement tend to manifest in age group 11-15 years old (p = 0.015) with odds ratio 3.1 (95% confidence interval, 1.2-8.1). Conclusion Renal involvement in children with HSP is more common in age group 11 to 15 years old.

Vogt-Koyanagi-Harada disease in an 8-year-old boy.

Vogt-Koyanagi-Harada (VKH) disease is an autoimmune disease involving pigmented tissue in eyes, auditory system, skin, and central nervous system. The pathogenesis is a result of T cell lymphocyte reaction against melanocyte component, tyrosinase and tyrosinase-related protein. This disease uniquely affected pigmented race in Asia and native America, mostly women aged 20-50. We reported an 8-years-old boy complained for visual disturbance since 6 weeks prior admission. Two years earlier, the parents noted the patient eyes were looked red when photographed (suggesting a dilated pupil) preceded by whitened on the right forehead and nose and whitened hair, eyebrow and eyelashes. The examination showed a vitiligo and skin atrophy on right frontal and right nasal, poliosis on the eyebrows, eyelids and hair. The diameter of right pupil was 8 mm, with a paresis on 3rd, 4th, 6th, and 9th nerves. Fundus examination revealed sunset glow appearance. The visual acuity on the right eye: 2/60, left eye: 1-0. Theres positive serology for antitoxoplasma IgG, anti Rubella IgG, anti CMV IgG. The patient was diagnosed with a VKH disease and then prescribed with methylprednisolone 1 mg/kg/day. The patient also had further follow up with dermatovenerologist and ophthalmologist. The eye examination revealed an improvement on right eye panuveitis, with a remaining keratic precipitate in the endothelium, and minimal flare and cell on the anterior chamber. ENT consultation revealed no ear inflammation or hearing disturbance.

474 Relationship Between Total Serum IgE, Atopy, and Obesity in Children With or Without Family History of Atopic Disease.

Background Prevalence of obesity and atopy had been increased simultanoeuosly. The relationship between obesity, atopy, and total serum IgE had been estimated. The aim of this study is to find out the relationship between total serum Ig E, atopy, and obese children with or without family history of atopic disease. Methods This was a cross sectional study. There were 160 children aged 6 to 11 years which were divided into 4 groups: obese children with and without family history of atopic disease and normal weight children with and without family history of atopic disease. Atopic was defined by positive result of one of allergens skin prick test and ECLIA method were done for total serum IgE. Significancy for categorical data used Chi-Square test. Logistic regression model were used to examine the relationship between obesity, total serum IgE, and atopy. Results We measured the total serum IgE of 155 children. The number of obese and normal weight children with family history of atopic disease who had high level of total serum IgE were 30 and 25 respectively, whereas these children who had normal level of total serum IgE were 6 and 15 respectively [OR = 1.9 (95% CI 0.9-3.9)]. On the other hand, obese and normal weight children without family history of atopic disease who had high level of total serum IgE were 21 and 11 respectively, whereas these children who had normal level of total serum IgE were 18 and 29 respectively [OR = 1.7 (95% CI 1.1-2.7)]. The number of obese and normal weight children without family history of atopic disease who had atopy were 38 and 9 respectively, whereas these children who had non-atopy were 2 and 31 respectively [OR = 13.3 (95% CI 3.5-52)], but there was no relationship between atopy and obesity in group with family history of atopic disease (P = 0.314). Conclusions There were relationship between high level of total serum IgE and obesity in group with and without family history of atopic disease and also relationship between atopy and obesity in group without family history of atopic disease.
