Clinical manifestations and outcomes of 420 children with Henoch Schönlein Purpura from a single referral center from Turkey: A three-year experience

A case series on recurrent and persisting IgA vasculitis (Henoch Schonlein purpura) in children

BACKGROUND

IgA vasculitis (IgAV) is a small vessel vasculitis that is more common in childhood. Very limited evidence exists on patients who experience an atypical disease course. The aim of this study was to describe a cohort of children diagnosed with recurrent or persisting IgAV to identify any themes associated with their disease course and areas of unmet needs.

METHODS

A single centre retrospective study of children diagnosed with recurrent or persisting IgAV at Alder Hey Children's Hospital (Liverpool, UK). Clinical data, including features at presentation and during follow up, potential triggers, abnormal laboratory and histology results, treatment and outcome at last clinical review were retrospectively collected. Key themes were identified.

RESULTS

A total of 13 children met the inclusion criteria (recurrent disease, n = 4; persisting disease, n = 9). Median age at first presentation was 10.2 years [2.6-15.5], female:male ratio 1.2:1. Children in the atypical cohort were significantly older than a larger cohort of children who followed a non-complicated disease course (median age 5.5 years (range [0.6-16.7], p = 0.003)). All children re-presented with a purpuric rash (either recurring or persisting), accompanied by joint involvement in 92% of patients (12/13). Disease-modifying anti-rheumatic drugs (DMARDs) were used in 8/13 (62%) children. The median time from first presentation to diagnosis of atypical disease was 18.4 months [5.3-150.8] and the time from first presentation to treatment was 24.1 months [1.8-95.4]. Use of corticosteroids was significantly higher in children with renal involvement (p = 0.026). During follow up, 8/13 (62%) children were admitted at least once, whilst 10/13 (77%) had re-presented at least once to the emergency department. Five (38%) children were referred to psychology services and 7 (54%) children reported feelings of frustration.

CONCLUSIONS

This series describes some characteristics of a small cohort of children with atypical IgAV. It also identifies unmet needs in children with atypical IgAV, which includes delays in diagnosis and lengthy waits for treatment, lack of high-quality evidence regarding treatment choices and a high unrecognised disease burden. Further research is needed to study this subgroup of children as evidence is lacking.

Severe gastrointestinal involvement in pediatric IgA vasculitis: a retrospective single-center cohort study in China

Objectives

The study aimed to describe the characteristics of gastrointestinal (GI) involvement in a cohort of hospitalized children with IgA vasculitis (IgAV) in China.

Method

We reviewed the records of hospitalized IgAV patients from January 2014 to December 2020 at one tertiary medical center. The patients were divided into the severe GI group and the non-severe GI group according to the presence of massive GI bleeding and complications. The clinical manifestations, laboratory factors, and treatment were analyzed between the two groups.

Results

A total of 1,179 patients were hospitalized due to IgAV. GI involvement was noted in 50% (589) of the patients, of whom 288 (48.9%) had severe GI involvement. GI complications were observed in 34 patients with IgAV with GI involvement. Rare onset age (<3 years or within 13-17 years), purpura above the waist, vomiting, high neutrophil-to-lymphocyte ratio, and decreased serum albumin were factors associated with severe GI involvement. Frequencies of renal involvement and biopsy-proven nephritis were higher in the severe GI group. The most commonly used medications were corticosteroids (100.0%) in the severe GI group. The maximum corticosteroid dose was higher (2.9 vs. 2.0 mg/kg), and more second-line therapies were needed (30.9% vs. 16.94%) in the severe GI group.

Conclusions

Severe GI involvement in children is common in our center. Rare onset age, purpura above the waist, vomiting, high neutrophil-to-lymphocyte ratio, and decreased serum albumin are associated with severe GI involvement. Patients with severe GI involvement need higher doses of corticosteroids and second-line therapy.

İnvajinasyonda Tedavi Yaklaşımı: Takip mi Cerrahi mı?

Objective: In this study, we describe the management and outcome of children with intussusception and analyze the sonographic findings that can be used to differentiate transient, self-limited small bowel intussusception from the cases with an indication for surgery. Material and Methods: We retrospectively reviewed the medical records of pediatric patients with the diagnosis of invagination who had been followed up in the pediatric surgery service between 2012-2017. Results: The median age was 39.5±35.9 (range 2-171) months. Among these patients, 57 (64%) had been followed up without surgery, and the remaining patients (n= 32, 36%) had undergone surgery. The median age of patients who had not undergone surgery was significantly greater than that of the patients who had undergone surgery (52.2±38.4 vs. 16.75±12.6; p

Clinicopathological Spectrum of Henoch-Schönlein Purpura Vasculitis: An Experience from a Tertiary Care Center

Henoch-Schönlein purpura (HSP) is a small vessel vasculitis with multiorgan involvement. Renal involvement is the key factor predicting morbidity. We have aimed to analyze the clinicopathological spectrum of HSP vasculitis and HSP nephritis to assess the risk factors associated with kidney involvement. This retrospective study was performed in the department of pathology with collaboration of department of dermatology and department of nephrology of a tertiary care center. All clinical details along with biopsy findings were retrieved. Starting materials of the study were cases of leukocytoclastic vasculitis with only perivascular IgA deposit of more than ++ in the absence of other immunoglobulin and trace complements. To investigate the possible factors that are influential on the development of biopsy-proven HSP nephritis, we divided the whole study population in two groups -group 1: with and group 2: without biopsy-proven nephritis. One-way analysis of variance was carried out during comparative analysis between two groups using IBM SPSS statistics software, version 19 and MedCalc software, version 12.3.0.0. HSP vasculitis comprised 11.6% (n = 19) of total cutaneous vasculitis in 2 years (164 cases) with a mean age of 13.52 ± 8.10 (range: 4-33 years). Three cases developed de novo kidney disease (15.79%). A correlation analysis revealed that predictors were seasonal variation (P = 0.018), severe gastrointestinal involvement (P = 0.03), and subcutaneous edema (P = 0.005). Various clinical and laboratory parameters were associated with renal consequences. Occult nephritis was the most common presentation with crescent as a constant histopathological feature.

Epidemiological and clinical aspects of immunoglobulin A vasculitis in childhood: a retrospective cohort study

Background

A retrospective study was conducted in order to investigate and describe the characteristics of Immunoglobulin A vasculitis (IgAV), previously known as Henoch-Schӧnlein purpura, in the paediatric population of a community-based healthcare delivery system in the Italian region of Abruzzo.

Methods

This is a population-based retrospective chart review of the diagnosis of IgAV in children ages 0 to 18, admitted to the Department of Paediatrics of Chieti and Pescara between 1 January 2000 and 31 December 2016. All children enrolled presented with clinical symptoms and laboratory findings and met the EULAR/PRINTO/PRES 2008 criteria.

Results

Two-hundred-eight children met the criteria for IgAV, with the highest incidence reported among children below 7-years of age. A correlation with recent infections was found in 64% of the cohort; the onset was more frequently during the winter and fall. Purpura had a diffuse distribution in the majority of patients; joint impairment was the second most frequent symptom (43%), whereas the gastrointestinal tract was involved in 28% of patients.

Conclusions

Hereby, we confirm the relative benignity of IgAV in a cohort of Italian children; with regards to renal involvement, we report a better outcome compared to other studies. However, despite the low rate of renal disease, we observed a wide use of corticosteroids, especially for the treatment of persistent purpura.

Successful Treatment of IgA Vasculitis With Prolonged Cutaneous Manifestation With Colchicine in a 10-Year-Old Boy

We report a 10-year-old boy with IgA vasculitis (IgAV) with prolonged cutaneous manifestations who was successfully treated with colchicine. At the age of 9, he was diagnosed as having IgAV by typical purpura, abdominal pain, and hematochezia. Initially, his severe gastrointestinal manifestation subsided by prednisolone 60 mg/day and intravenous methylprednisolone pulse therapy. However, his gastrointestinal manifestation was glucocorticoid-dependent and refractory to factor XIII concentrate, intravenous immunoglobulin G, and mycophenolate mofetil. His abdominal pain and hematochezia responded to the combination therapy with dapsone and low dose of prednisolone 5 mg/day and did not relapse even after discontinuation of dapsone. On the other hands, the effect of dapsone on his cutaneous manifestation was dose-dependent. As well dapsone had no glucocorticoid-sparing effect. Approximately 12 months after onset, colchicine treatment was started, which resulted in remission of his chronic cutaneous manifestation. After prednisolone was tapered off, his cutaneous manifestation is currently well-controlled on colchicine 0.5 mg/day without adverse events. He had never complicated by kidney involvements. In conclusion, colchicine treatment exerts a beneficial effect in IgAV patients with prolonged cutaneous manifestation refractory to multiple drugs.

Neutrophil to Lymphocyte Ratio and Gastrointestinal Involvement Among Henoch Schonlein Purpura Patients: A Systematic Review and Meta-Analysis

Neutrophil to lymphocyte ratio has been examined among several studies regarding Henoch Schonlein purpura patients with gastrointestinal involvement. The current meta-analysis aims to evaluate neutrophil to lymphocyte ratio differences between Henoch Schonlein purpura patients with and without gastrointestinal manifestations.An extensive search of the available literature was done using MEDLINE (1966-2020), Clinicaltrials.gov (2008-2020), Cochrane Central Register of Controlled Trials (CENTRAL) (1999-2020) and Google Scholar (2004-2020) databases and statistical analysis was mainly conducted using RevMan 5.3 software.The current meta-analysis is based on data from six studies. Neutrophil to lymphocyte ratio was higher in Henoch Schonlein patients with gastrointestinal involvement than those without with a mean difference of 0.88 (95% confidence interval [CI]: 0.55, 1.22 [P < 10-5, I2 = 8%]). Low heterogeneity (I2) was observed between the included studies. Subgroup analysis, leave one out meta-analysis and meta-regression analysis were performed which led to the lowering of I2 to 0.The findings of our meta-analysis suggest that the neutrophil to lymphocyte ratio could serve as a marker of gastrointestinal involvement in patients with Henoch Schonlein purpura; however, most of the included studies are case-control, therefore future cohort studies should clarify the value of this marker.

A randomized controlled trial on the effect of dietary guidance on the treatment of Henoch-Schonlein purpura in children

The amino acid-based formulae were extensively added to diet of children for the treatment of Henoch-Schonlein purpura (HSP), and the nutrition and growth situation of children were evaluated after giving new dietary intervention. Patients were randomly divided into restricted diet group (n=30) and dietary guidance group (n=30). Besides, 30 cases with bronchiolitis who had normal diet were selected as the control group. The dietary questionnaire was designed to record the types and intakes of various foods taken by children every day, and the intake levels of nutrients were analyzed. Physical examination, biochemical analysis of blood and urine routine were carried out to evaluate the effect of dietary guidance on their growth and development. The results showed that restricted diet group had lower levels of nutrient intake and the actual/recommended percentage. However, overall nutrient intake level of the dietary guidance group was higher, basically equal to the recommended intake level. Besides, the actual intake and actual/recommended percentage of nutrients of dietary guidance group were significantly higher than those of restricted diet group (p<0.05). Dietary guidance can improve nutrients and protein intake of children with HSP, and reduce the relapse of rash and incidence of complications.

Risk factors for intussusception in children with Henoch-Schönlein purpura: A case-control study

BACKGROUND

The etiology of Henoch-Schönlein purpura (HSP) with intussusception remains undefined.

AIM

To investigate the risk factors for intussusception in children with HSP and gastrointestinal (GI) involvement.

METHODS

Sixty children with HSP and concomitant intussusception admitted to the Beijing Children’s Hospital of Capital Medical University between January 2006 and December 2018 were enrolled in this study. One hundred pediatric patients with HSP and GI involvement but without intussusception, admitted to the same hospital during the same period, were randomly selected as a control group. The baseline clinical characteristics of all patients, including sex, age of onset, duration of disease, clinical manifestations, laboratory test results, and treatments provided, were assessed. Univariate and multiple logistic regression analyses were performed to identify possible risk factors.

RESULTS

The 60 children in the intussusception group comprised 27 girls (45%) and 33 boys (55%) and the 100 children in the non-intussusception group comprised 62 girls (62%) and 38 boys (38%). The median age of all patients were 6 years and 5 mo. Univariate and multiple regression analyses revealed age at onset, not receiving glucocorticoid therapy within 72 h of emergence of GI symptoms, hematochezia, and D-dimer levels as independent risk factors for intussusception in children with HSP (P < 0.05).

CONCLUSION

The four independent risk factors for intussusception in pediatric HSP with GI involvement would be a reference for early prevention and treatment of this potentially fatal disease.

Gastrointestinal involvement in IgA vasculitis: a single-center 11-year study on a cohort of 118 children

INTRODUCTION AND OBJECTIVES

Immunoglobulin A vasculitis (IgAV), the most common childhood vasculitis, is associated with gastrointestinal (GI) involvement in 50-75% of cases. The aim of this study was to describe the characteristics of GI involvement in a cohort of hospitalized children with IgAV.

METHODS

We retrospectively evaluated patients hospitalized for IgAV at Meyer Children's University Hospital, from January 2010 to December 2020. The children's families were interviewed by phone and asked about disease relapses.

RESULTS

In the study period, 118 children had GI involvement, corresponding to 75% of children hospitalized for IgAV. Their median age was 7 years (interquartile range 6-9). The most frequent GI manifestations were abdominal pain (96%), bleeding (71%, mostly occult), vomiting (58%), and diarrhea (17%). GI complications, observed in 18%, were intussusception (14%), appendicitis (3%), gallbladder hydrops (2%), and ileal perforation (1%). Abdomen ultrasound, performed in all cases, was abnormal in 68%. Abdomen X-ray, performed in 19 patients, showed pathologic findings in 84% of them. Selected children with severe manifestations also underwent abdomen computed tomography (2/118; 2%) and GI endoscopy (5/118; 4%). Steroids were used in 80 (67.8%) cases. The use of second- and third-line therapies was necessary in three cases. Relapses, investigated in 80 cases (68%), occurred in 21% of them. Key Points • The present retrospective study describes a cohort of 118 patients hospitalized for gastrointestinal (GI) involvement in immunoglobulin A vasculitis (IgAV) at a tertiary care children's hospital from January 2010 to December 2020. • The most frequent GI manifestations were abdominal pain (96%), vomiting (58%), and diarrhea (17%). GI bleeding was reported in 71% of children, and it was occult in most cases. • GI complications, occurring in 18% of cases, were intussusception (14%), appendicitis (3%), gallbladder hydrops (2%), and ileal perforation (1%). • Steroid treatment has been successfully used in severe GI manifestations; however, our data do not support its association with low relapse risk.

CONCLUSIONS

The present study describes a large pediatric cohort of GI involvement in IgAV. Steroid treatment should be used when GI manifestations are severe. The association of steroid use with relapse risk is not currently established.

Influence of transitional nursing on the compliance behavior and disease knowledge of children with purpura nephritis

BACKGROUND

Purpura nephritis, also called Henoch-Schönlein purpura nephritis, is a systemic disease with small dead vasculitis as the main pathological change.

AIM

To observe the influence of transitional nursing activities on the compliance behaviors and disease knowledge of children with purpura nephritis.

METHODS

A total of 82 children with purpura nephritis were included and divided into a general nursing group (41 children) and transitional nursing group (41 children) using the envelope method. The general nursing group received routine nursing care, while the transitional nursing group received transitional nursing care. The behaviors, knowledge of the disease, and self-management ability of the two groups were evaluated after nursing care was provided.

RESULTS

The scores of four items (self-care ability, self-responsibility, health knowledge level, and self-concept) in the transitional nursing group were significantly higher than those in the general nursing group.

CONCLUSION

Transitional nursing can directly improve the disease knowledge level and self-management ability of children with purpura nephritis and effectively reduce complications.

Rheumatic diseases in Syrian refugee children: a retrospective multicentric study in Turkey

Since the Syrian civil war in 2011, an estimated number of 3.6 million Syrian refugees crossed into Turkey, and almost half of them were children. The distribution of rheumatic diseases in Syrian refugee children is not known. The aim of this study was to describe the profile of rheumatic diseases in Syrian refugee children living in Turkey. The demographic data, clinical and laboratory findings, medications, complications and outcome results of Syrian refugee children who had visited Pediatric Rheumatology Departments of University of Health Science Kanuni Sultan Süleyman Research and Training Hospital, Ümraniye Research and Training Hospital, Şanlıurfa Research and Training Hospital, and Cengiz Gökçek Maternity and Gynecology Hospital between April 1, 2011, and September 1, 2019, were evaluated retrospectively. A total of 151 patients were included in the study. Among them, 51 patients had juvenile idiopathic arthritis (JIA), 49 had familial Mediterranean fever (FMF), 43 had vasculitis, and 8 had connective tissue diseases. Homozygous M694V mutation was the most common mutation among FMF patients. Oligoarticular JIA (41.2%) was the most frequent type of JIA, and enthesitis-related arthritis (ERA) (27.5%) was the second one. The frequency of systemic JIA was 11.8%. One patient with SLE died due to complicated meningitis. This is the first study evaluating the distribution of rheumatic diseases in Syrian refugee children. Clinical follow-up of rheumatologic diseases is difficult in Syrian refugees due to language barriers, social and cultural differences. Health care systems should be well organized to provide appropriate care to asylum seekers.
