Tumor necrosis factor receptor-associated cycle syndrome: a case report and literature review.

Recurring episodes of fever characterize tumor necrosis factor receptor-associated periodic syndrome (TRAPS) which is autosomal dominant. The primary symptoms of patients with TRAPS include prolonged fever, abdominal pain, muscle pain, and skin rashes. The prevalence of TRAPS appeared higher in Western countries than in Asian countries. Herein, we present the case of a 13-year-old girl who experienced intermittent fever for 8 years, with episodes that occur every 2 years. The patient demonstrated periodic fever, headache, vomiting, rash, and elevated inflammatory marker levels during the disease course. A heterozygous C55Y mutation was identified via a direct DNA sequencing of her genomic DNA. This mutation is located in exon 4 of TNFRSF1A. Genetic studies of her sister and mother revealed that they possessed the C55Y heterozygous mutation without demonstrating any clinical signs, while the father did not. Further, we conducted a thorough assessment of the literature and compiled the information from the eight TRAPS case series.

Testicular ischemia associated with IgA vasculitis in a child: a case report and literature review.

Testicular necrosis is a rare and severe complication of immunoglobulin A (IgA) vasculitis (IgAV). Herein, We report a case of a 10-year-old boy who was admitted to the hospital due to skin purpura and intermittent abdominal pain for 10 days and bilateral testicular pain for 2 days. Scrotal ultrasonography indicated right testicle ischemia, right epididymo-orchitis, and bilateral hydrocele of the testis. Scrotal surgical exploration revealed significant swelling and darkening of the right testicle. Conservative treatment led to improvement in his condition, and he was discharged. During 3 months of follow-up, there was no recurrence of skin purpura or pain, and the urine tests were normal. Color ultrasound indicated only partial blood flow signal to the right testicle tissue, which was slightly smaller than the left testicle. This case highlights the need for continuous attention from clinicians to the signs and symptoms of the reproductive system during the diagnosis and treatment of IgAV. Continuous monitoring with ultrasound can aid in early detection, diagnosis, and treatment of reproductive system lesions of IgA vasculitis.

Clinical characteristics and associating risk factors of gastrointestinal perforation in children with IgA vasculitis.

BACKGROUND: IgA vasculitis (IgAV) is a common small vessel vasculitis in children. Gastrointestinal perforation (GP) rarely presents as a complication of IgAV and is not well characterized. This study is aimed to investigate the clinical features, diagnosis, and risk factors of GP in children with IgAV. METHODS: We retrospectively reviewed the clinical data of children with IgAV who attended our hospital between January 2014 and June 2018. The clinical risk factors and the corresponding treatments were analyzed for the children with IgAV complication with GP. RESULTS: In total, 10,791 children with IgAV were reviewed in this study. GP was observed in 11 children with IgAV, accounted for 0.10% of the total cases. Among those GP patients, 1 case was gastric perforation, 10 cases were intestinal perforation. Five GP cases were identified by abdominal CT. Ultrasonography was failed to detect the occurrence of GP in five cases. The average duration of abdominal pain in the GP cases was 9.3 days, and 9 cases (81.8%) presented with abdominal pain for over 7 days. Gastric/intestinal perforation repair were performed for 3 IgAV GP cases under open surgery. The other eight cases were treated through enterectomy. In comparison with the patients without GP, the GP patients had significant higher rates in the aspect of the abdominal or mixed type of IgAV, abdominal pain duration more than 7 days, hematochezia, renal damage, and methylprednisolone treatment with the daily dosage more than 2 mg/kg. CONCLUSION: GP children accounted for 0.10% of the total IgAV cases. The risk of GP is elevated in IgAV patients who has gastrointestinal symptoms and/or other symptoms such as hematochezia, renal damage, a prolonged abdominal pain (>7 days), administration of methylprednisolone (>2 mg/kg). Abdominal CT is highly recommended for the early detection of GP in IgAV patients.Key messagesGastrointestinal perforation (GP) rarely presents as a complication of IgAV and is not well characterized.11 out of 10,791 children with IgAV developed GP, accounting for 0.10% of the total number of cases.Abdominal CT is highly recommended for the early detection of GP in IgAV patients.

[Long-term effect of Tripterygium Glycosides Tablets combined with traditional Chinese medicine on adulthood fertility].

To preliminarily investigate the effect of Tripterygium Glycosides Tablets( TGT) combined with traditional Chinese medicine( TCM) on the fertility and female menstruation on persons who have took during childhood. The children with henoch-schonlein purpura( HSP) or henoch-schonlein purpura nephritis( HSPN) who treated with TGT under 18 years old and now older than 18 years old( including 18 years old) during January 1998 to December 2010 were selected in our research. The content of follow-up visit included marriage,marriage age,fertility and child health; and unmarried female patients were asked whether they had menstrual abnormalities. The data of the unmarried female patients,including age,clinical classification,TCM syndrome type,initial dose and other related factors that may affect menstrual cycle,was analyzed by using binary logistic regression analysis. A total of 195 patients who met the criteria were followed up in this study,and 26 patients married for more than 1 year. Among the 26 married patients,1 HSP patient had no birth planning due to rheumatoid arthritis,and the remaining 25 patients all had given birth or were pregnant. The 169 unmarried patients included 89 female patients. Among the 89 female patients,4 cases refused to tell the menstrual situations,72 cases had normal menstruation( 84. 7%),13 cases had abnormal menstruation( 15. 3%),and there was no case of amenorrhea. Logistic regression analysis results showed that the age,clinical classification,TCM syndrome type and initial dose had no correlation with abnormal menstruation. Our results demonstrated that TGT has no effect on adulthood fertility among patients who took TGT combined with traditional Chinese medicine during childhood.

Correlation between endocapillary proliferative and nephrotic-range proteinuria in children with Henoch-Schönlein purpura nephritis.

BACKGROUND: The endocapillary proliferative (EP) lesion is not included in the International Study of Kidney Disease in Children (ISKDC) pathological classification of Henoch-Schönlein purpura nephritis (HSPN). The main objective of the study was to determine the pathological importance of EP in the development of proteinuria in children with Henoch-Schönlein purpura nephritis (HSPN). METHODS: The pathological features of 148 HSPN children with nephrotic-range proteinuria were investigated retrospectively. Urinary IgG, transferrin, and albumin levels were measured by immunonephelometry. The correlations between EP lesion and 24-h proteinuria, urinary IgG, urinary transferrin, and urinary albumin were analyzed. Renal biopsy specimens were immunohistochemically stained for nephrin and podocalyxin. RESULTS: Of the total 581 cases of children with HSPN who underwent renal biopsy, 148 cases (25.5%) presented with nephrotic-range proteinuria. The pathological types of HSPN with nephrotic-range proteinuria were categorized as IIb, IIIa, IIIb, IIIb with diffuse EP, IVb, pure focal EP type, and pure diffuse EP type. Among these types, pure diffuse EP type accounted for 7.4%. The levels of 24-h proteinuria and urinary albumin were the highest in pure diffuse EP type among all pathological types, and the percentage of EP correlated with 24-h proteinuria and urinary albumin levels. 24-h proteinuria was significantly higher in pure diffuse EP type relative to HSPN IIb type, and significantly higher in IIIb with EP, compared with HSPN IIIb. Nephrin, but not podocalyxin, was downregulated in EP segment. CONCLUSIONS: EP is an independent pathogenic factor in HSPN with nephrotic-range proteinuria. Downregulation of nephrin in EP segment is a potential molecular mechanism of nephrotic-range proteinuria. Albumin is the major urinary protein component in HSPN with EP.

Clinicopathological features and prognosis of membranoproliferative-like Henoch-Schönlein purpura nephritis in children.

BACKGROUND: The aim of this retrospective study was to define the clinical manifestations, pathological features and prognosis of children with membranoproliferative-like Henoch-Schönlein purpura nephritis (HSPN), representing International Study of Kidney Disease in Children (ISKDC) grade VI. METHODS: Among 245 patients with HSPN treated in our hospital between 2008 and 2010, nine patients (3.7%) were diagnosed with HSPN of ISKDC grade VI (males = 5, females = 4, age: 9.5 ± 2.03 years, mean ± SD). The clinical features, laboratory and pathological findings, treatment and outcome of the 9 patients were retrospectively analyzed. RESULTS: Of the 9 patients, 7 (78%) presented with hematuria and nephrotic syndrome, and were treated with steroids (oral prednisone or intravenous methylprednisolone pulse therapy) and immunosuppressants (oral tripterygium glycosides or intravenous cyclophosphamide pulse therapy). One (11%) patient had hematuria and nephrotic range proteinuria (> 50 mg/kg per 24 hours) and was treated with oral prednisone and tripterygium glycosides. Another (11%) patient presented with hematuria and moderate proteinuria (25-50 mg/kg per 24 hours) and was treated with oral tripterygium glycoside only. Histopathological examination showed diffuse glomerular mesangial and endocapillary proliferation, mesangial interposition, double-contour formation, podocyte hypertrophy, shedding, and cytoplasmic absorption droplets. The percentages of glomeruli with small cellular crescents varied from 4%-25% in 6 of 9 patients. Follow-up for 2 to 4 years showed excellent recovery in all patients. CONCLUSIONS: The main clinical feature of ISKDC grade VI HSPN in children is a nephrotic syndrome with hematuria. The excellent prognosis of the disease was probably related to early diagnosis and treatment with steroids and/or immunosuppressants, and mild degree of glomerulosclerosis and tubulointerstitial damage.

Steroids combined with levothyroxine to treat children with idiopathic nephrotic syndrome: a retrospective single-center study.

BACKGROUND: The clinical efficacy and safety of low-dose levothyroxine in the treatment of idiopathic nephritic syndrome accompanied by thyroid dysfunction have not been established. METHODS: One hundred and sixty-four patients were divided into three groups according to the levels of thyroid hormone and treatment. The thyroid status, efficacy and adverse reactions of thyroid treatment were observed in each group. RESULTS: Thyroid dysfunction was found in 73 patients. 40 cases were treated with steroids combined with levothyroxine. Proteinuria, cholesterol and thyroid-stimulating hormone (TSH) levels were significantly higher in patients with thyroid dysfunction, whereas serum albumin and free and total T3 and T4 levels were lower than those of euthyroid patients. The time for proteinuria remission in patients receiving levothyroxine therapy was shorter and their serum albumin higher than for patients without levothyroxine treatment. CONCLUSIONS: Thyroid hormonal changes are related to the degree of both proteinuria and serum albumin in patients with INS. Combined treatment with low-dose levothyroxine supplementation and steroids in children with INS and thyroid dysfunction is associated with reduced proteinuria and increased plasma albumin compared with patients treated with steroids only.

A case of anaphylactoid purpura nephritis accompanied by pulmonary hemorrhage and review of the literature.

Cases of Henoch-Schönlein purpura and purpura nephritis accompanied by pulmonary hemorrhage are rare. Mild cases are easily ignored due to a lack of evident bleeding, and severe cases may be fatal. We have only treated one patient with Henoch-Schönlein nephritis (HSPN), a female child. The clinical manifestations were not evident, however, the imaging manifestations were clear. Finally, the patient was definitively diagnosed with HSPN accompanied by pulmonary hemorrhage. Following treatment with antiinflammatory and steroidal agents, tripterygium glycosides and traditional Chinese medicine, the patient recovered. In the present study, we report the diagnosis and treatment of this disease, with a review of the literature.

Baicalein induces apoptosis in esophageal squamous cell carcinoma cells through modulation of the PI3K/Akt pathway.

Baicalein, a flavone present in Scutellaria baicalensis Georgi, has been demonstrated to possess antitumor activity in a variety of cancer cells in vitro. However, its effects on the growth inhibition and induction of apoptosis in human esophageal carcinoma cells remain unclear. The aims of this study were to determine whether cultured EC-109 esophageal squamous cell carcinoma (ESCC) cells undergo apoptosis when treated with baicalein and to investigate the underlying mechanisms in vitro. Cell growth was measured using MTT and plate colony formation assays. Induction of apoptosis was examined using Hoechst 33258 staining, flow cytometry analysis and a DNA fragmentation assay. The mechanisms underlying the observed growth suppression were examined using western blot analysis. The results demonstrated that treatment of EC-109 cells with baicalein for 48 h markedly decreased the rate of cell viability. Colony formation was almost fully suppressed at 40 µM baicalein. EC-109 cells underwent apoptosis in response to baicalein treatment, demonstrated by an increase in the percentage of cells stainable with Hoechst 33258 and Annexin V-FITC/PI, increased DNA fragmentation and activation of the intrinsic (mitochondrial) pathway for cell death. The latter was characterized by increased expression of the cleaved forms of caspase-9 and -3, and poly (ADP-ribose) polymerase (PARP). Additionally, baicalein was found to downregulate anti-apoptotic components and upregulate apoptotic components of the PI3K/Akt pathway. In conclusion, baicalein induces apoptosis in EC-109 cells through modulation of the PI3K/Akt pathway, thus providing further understanding of the molecular mechanisms of baicalein action in esophageal carcinoma. Therefore, the present study revealed that baicalein significantly inhibits growth and induces apoptosis in EC-109 human ESCC cells in vitro.
