Development of clinical and laboratory biomarkers in an international cohort of 428 children with lupus nephritis.

BACKGROUND: Lupus nephritis (LN) is a very severe manifestation of lupus. There is no consensus on which treatment goals should be achieved to protect kidney function in children with LN. METHODS: We retrospectively analyzed trends of commonly used laboratory biomarkers of 428 patients (≤ 18 years old) with biopsy-proven LN class ≥ III. We compared data of patients who developed stable kidney remission from 6 to 24 months with those who did not. RESULTS: Twenty-five percent of patients maintained kidney stable remission while 75% did not. More patients with stable kidney remission showed normal hemoglobin and erythrocyte sedimentation rate from 6 to 24 months compared to the group without stable kidney remission. eGFR ≥ 90 ml/min/1.73m2 at onset predicted the development of stable kidney remission (93.8%) compared to 64.7% in those without stable remission (P < 0.00001). At diagnosis, 5.9% and 20.2% of the patients showed no proteinuria in the group with and without stable kidney remission, respectively (P = 0.0001). dsDNA antibodies decreased from onset of treatment mainly during the first 3 months in all groups, but more than 50% of all patients in both groups never normalized after 6 months. Complement C3 and C4 increased mainly in the first 3 months in all patients without any significant difference. CONCLUSIONS: Normal eGFR and the absence of proteinuria at onset were predictors of stable kidney remission. Significantly more children showed normal levels of Hb and erythrocyte sedimentation rate (ESR) from 6 to 24 months in the group with stable kidney remission.

The dynamics of laboratory markers reflecting cytokine overproduction in macrophage activation syndrome complicated with systemic juvenile idiopathic arthritis.

OBJECTIVES: To validate the correlation between laboratory markers reflecting disease activity of macrophage activation syndrome (MAS) and serum cytokine levels and identify the valuable laboratory markers that change over time for a prompt MAS diagnosis. METHODS: Serum cytokine levels were determined by enzyme-linked immunosorbent assay and compared with laboratory markers reflecting MAS disease activity.The changes in values were evaluated from the acute phase of systemic juvenile idiopathic arthritis (s-JIA) to MAS diagnosis. RESULTS: CXCL9 was significantly correlated with aspartate aminotransferase (AST), lactate dehydrogenase (LDH), D dimer, and urine ß2 microglobulin levels. sTNF-RII was significantly correlated with platelet counts, AST, LDH, D dimer, and ferritin levels. Significant changes in platelet count, LDH, and D dimer levels were observed. Decreased platelet counts were the most valuable indicator for MAS diagnosis. CONCLUSION: Monitoring the laboratory markers that change over time, particularly decreased platelet counts, was valuable for the prompt MAS diagnosis in s-JIA.

Clinical significance of serum cytokine profiles for differentiating between Kawasaki disease and its mimickers.

OBJECTIVES: To investigate the clinical significance of serum cytokine profiles for differentiating between Kawasaki disease (KD) and its mimickers. METHODS: Patients with KD, including complete KD, KD shock syndrome (KDSS), and KD with macrophage activation syndrome (KD-MAS), and its mimickers, including multisystem inflammatory syndrome in children, toxic shock syndrome, and Yersinia pseudotuberculosis infection, were enrolled. Serum levels of interleukin (IL)-6, soluble tumor necrosis factor receptor type II (sTNF-RII), IL-10, IL-18, and chemokine (C-X-C motif) ligand 9 (CXCL9) were measured using enzyme-linked immunosorbent assay and compared them with clinical manifestations. RESULTS: Serum IL-6, sTNF-RII, and IL-10 levels were significantly elevated in patients with KDSS. Serum IL-18 levels were substantially elevated in patients with KD-MAS. Patients with KD-MAS and KD mimickers had significantly elevated serum CXCL9 levels compared with those with complete KD. Area under the receiver operating characteristic curve analysis showed that serum IL-6 was the most useful for differentiating KDSS from the others, IL-18 and CXCL9 for KD-MAS from complete KD, and CXCL9 for KD mimickers from complete KD and KD-MAS. CONCLUSION: Serum cytokine profiles may be useful for differentiating between KD and its mimickers.

Safety and efficacy of vedolizumab in pediatric patients with ulcerative colitis: multicenter study in Japan.

BACKGROUND: Vedolizumab (VDZ) is a humanized monoclonal antibody that binds to α4ß7 integrin expressed in T-lymphocytes and is gut selective. Few studies have evaluated the safety and efficacy of VDZ in pediatric ulcerative colitis (UC) patients, especially from Asia. METHODS: A longitudinal multicenter retrospective study was conducted at 10 Japanese tertiary medical institutions. Patients aged ≤18 years old who received VDZ for UC between January 2019 and July 2021 were enrolled. Information on the clinical characteristics, prior/concomitant treatment, and safety during the observation period was collected. RESULTS: The data obtained from 48 patients (males, n = 30; females, n = 18) were analyzed. The median age at VDZ induction was 14 (range 4-18) years old. VDZ was indicated in 73% of patients as switching from previous biologics due to primary failure, loss of response, and adverse events (AEs) and was the first biologic in 27%. Remission was achieved or maintained at weeks 14, 30, and 54 in 79.2%, 75.0%, and 65.8% of patients, respectively. There were no significant differences between the number of previous biologics exposures and VDZ effectiveness. The hematocrit, serum albumin concentrations, and erythrocyte sedimentation rate (ESR) at baseline differed significantly by VDZ effectiveness. Nine AEs, including infusion reaction, were noted in seven (14.3%) patients. There were no severe AEs related to VDZ administration. CONCLUSIONS: VDZ was safe and effective in children with UC. The hematocrit, albumin, and ESR at VDZ initiation might be predictors for VDZ effectiveness. VDZ may be an important option for pediatric patients and can be used as an alternative to immunomodulators.

International cohort of 382 children with lupus nephritis - presentation, treatment and outcome at 24 months.

BACKGROUND: Children with lupus have a higher chance of nephritis and worse kidney outcome than adult patients. METHODS: We retrospectively analyzed clinical presentation, treatment and 24-month kidney outcome in a cohort of 382 patients (≤ 18 years old) with lupus nephritis (LN) class ≥ III diagnosed and treated in the last 10 years in 23 international centers. RESULTS: The mean age at onset was 11 years 9 months and 72.8% were females. Fifty-seven percent and 34% achieved complete and partial remission at 24-month follow-up, respectively. Patients with LN class III achieved complete remission more often than those with classes IV or V (mixed and pure). Only 89 of 351 patients maintained stable complete kidney remission from the 6th to 24th months of follow-up. eGFR ≥ 90 ml/min/1.73 m2 at diagnosis and biopsy class III were predictive of stable kidney remission. The youngest and the oldest age quartiles (2y-9y, 5m) (14y, 2m-18y,2m) showed lower rates of stable remission (17% and 20.7%, respectively) compared to the two other age groups (29.9% and 33.7%), while there was no difference in gender. No difference in achieving stable remission was found between children who received mycophenolate or cyclophosphamide as induction treatment. CONCLUSION: Our data show that the rate of complete remission in patients with LN is still not high enough. Severe kidney involvement at diagnosis was the most important risk factor for not achieving stable remission while different induction treatments did not impact outcome. Randomized treatment trials involving children and adolescents with LN are needed to improve outcome for these children. A higher resolution version of the Graphical abstract is available as Supplementary information.

Analysis of the ratio of urinary beta-2-microglobulin to total protein concentration in children with isolated tubulointerstitial disease.

BACKGROUND: Proteinuria is broadly classified into glomerular and tubular proteinuria. Urinary beta-2-microglobulin (ß2-MG) is known as a marker for detecting tubulointerstitial diseases. However, tubulointerstitial damage can also lead to an increase in urinary ß2-MG level in some patients with glomerular diseases. This study aimed to determine the ratio of urinary ß2-MG to total protein (TP) concentration in patients with both isolated tubulointerstitial and glomerular disease. METHODS: This multicenter, retrospective study included children with Dent disease or lupus nephritis in five facilities. Their urinary ß2-MG levels were > 1000 µg/L. Urinary ß2-MG and TP concentrations were obtained, and the ratio of urinary ß2-MG to TP concentration (µg/mg) was calculated. The Mann-Whitney U test was performed to compare this ratio between these children. The optimal cutoff value of the ratio for considering the presence of glomerular disease was obtained from the receiver operating characteristic (ROC) curve. RESULTS: We obtained information on 23 children with Dent disease and 14 children with lupus nephritis. The median ratios of urinary ß2-MG to TP concentrations in children with Dent disease and lupus nephritis were 84.85 and 1.59, respectively. The ROC curve yielded the optimal cutoff value of this ratio for distinguishing between these diseases, and the cutoff value was found to be 22.3. CONCLUSION: In children with tubulointerstitial diseases, the urinary ß2-MG concentration may be approximately 8.5% of the TP concentration. The possibility of presenting with glomerular disease should be considered in patients with a ratio of urinary ß2-MG to TP concentration of < 22.3 (µg/mg).

Risk factors for intolerance of oral 5-aminosalicylic acid preparations in pediatric ulcerative colitis.

BACKGROUND: No previous study of Japanese children with ulcerative colitis (UC) has reported the risk factors for intolerance of 5-aminosalicylic acid (5-ASA). We aimed to identify risk factors for intolerance of oral 5-ASA preparations in pediatric UC. METHODS: Patients with childhood-onset UC who were seen at our hospital between November 2003 and March 2020 were investigated. Intolerance of 5-ASA was defined as having clinical symptoms (pyrexia, abdominal pain, diarrhea, bloody stool) that worsened after starting oral administration of 5-ASA and improved after discontinuation of 5-ASA. Patient sex, age, body size, laboratory data, pediatric UC activity index scores, and colonoscopy-based determinations of the extent and severity of the affected lesion at initiation of 5-ASA of intolerant and tolerant groups were compared. RESULTS: Fifteen patients were in the intolerant group, and 37 were in the tolerant group. The leukocyte count, C-reactive protein level, and erythrocyte sedimentation rate were significantly higher in the intolerant group than the tolerant group; the albumin level in the intolerant group was significantly lower. All intolerant patients and 68% of tolerant patients had pancolitis (Paris classification E4). Patients with a large, affected area (Paris classifications E3 and E4) more frequently had intolerance to 5-ASA than patients with a small lesion. The cumulative Mayo endoscopic subscore (cMES), which is the sum of MES scores for six regions of the large intestine, was significantly higher in the intolerant group. CONCLUSIONS: Pediatric UC patients with more intense inflammation and a large lesion could have an increased risk of intolerance for 5-ASA.

Association of steroid administration with larger coronary artery abnormalities in patients with Kawasaki disease.

We sought to elucidate the risk profiles of patients with Kawasaki disease who developed coronary artery abnormalities through a retrospective analysis with special reference to steroid treatment. Demographics of the patients were obtained from medical records, and characteristics of the coronary artery abnormalities were evaluated by echocardiography and coronary angiography, which included number, location, size, and length of coronary artery abnormalities (we evaluated by cardiac catheterisation with the American Heart Association classification with segments). We divided the patients into two groups based on steroid use and compared their characteristics and the complications of coronary artery abnormalities and cardiac events. A total of 29 patients were diagnosed with coronary artery abnormalities by echocardiography and coronary angiography during the study period (24 male; median age, 24 months [range: 2-84 months]). Eighteen patients were treated with aspirin and intravenous immunoglobulin (63%, non-steroid group), whereas 11 received aspirin and intravenous immunoglobulin plus steroids (37%, steroid group). No significant differences were found in the number and location of coronary artery abnormalities between the steroid and non-steroid groups. However, the size and number of segments for coronary artery abnormalities were significantly larger and shorter, respectively, in the steroid group (z-score: non-steroid group 6.3 versus steroid group 8.7; p < 0.01). The coronary artery abnormality segments under steroid use were also shorter (non-steroid group versus steroid group, two segments versus one segment; p = 0.02). Coronary artery abnormality size was larger in patients who used steroids than that of non-steroids. This study showed that steroid use significantly affected coronary artery abnormality size in patients with Kawasaki disease. However, cardiac complications from coronary artery abnormalities and cardiac events were comparable between the steroid and non-steroid groups. Further prospective, multicentre studies are needed to confirm these findings.

Long-term efficacy and safety of canakinumab in the treatment of systemic juvenile idiopathic arthritis in Japanese patients: Results from an open-label Phase III study.

OBJECTIVES: The objective of the study was to report the efficacy and safety of canakinumab treatment in Japanese patients with systemic juvenile idiopathic arthritis (sJIA) over a 48-week study period. METHODS: Patients were administered canakinumab 4 mg/kg (maximum dose 300 mg) every 4 weeks, with no dose adjustments. The key outcome measures included adapted American College of Rheumatology paediatric (aACR pedi) 30/50/70/90/100 response, proportion of patients with inactive disease, and corticosteroid (CS) tapering. RESULTS: In total, 16/19 (84.2%) patients received canakinumab for ≥96 weeks reaching end-of-study (EOS) visit without premature discontinuation. Regardless of the level of joint involvement at baseline, high aACR pedi responses were observed throughout the study; at the EOS, aACR pedi 90/100 response rates were 84.2%/63.2%, respectively. The proportion of patients who successfully tapered CSs at EOS was 66.7% (12/18), of which 10 patients were steroid-free. The most common adverse events were infections (238.3 events/100 patient-years). Serious adverse events were observed in 52.6%. The event (n=1) adjudicated as possible macrophage activation syndrome was preceded by sJIA flare. No deaths were reported. CONCLUSIONS: Canakinumab treatment resulted in a sustained treatment response in sJIA patients over 48 weeks and was associated with CS tapering in majority of patients. No new safety findings were reported.

Defining renal remission in an international cohort of 248 children and adolescents with lupus nephritis.

OBJECTIVE: We studied the rate of remission of LN in an international cohort of 248 children and adolescents with biopsy-proven LN. Five different definitions from scientific studies and the definitions recommended by the ACR and Kidney Disease: Improving Global Outcomes were used. METHODS: Anonymized clinical data in patients with biopsy-proven LN class ≥III (International Society of Nephrology/Royal Pathology Society) diagnosed and treated in the last 10 years in 23 international centres from 10 countries were collected. We compared the rate of patients in complete and partial remission applying the different definitions. RESULTS: The mean age at diagnosis was 11 years and 4 months, and 177 were females. The number of patients in complete and partial remission varied a great deal between the different definitions. At 24 months, between 50% and 78.8% of the patients were in full remission as defined by the different criteria. The number of patients in partial remission was low, between 2.3% and 25%. No difference in achieved remission was found between boys and girls or between children and adolescents (P > 0.05). Patients with East Asian ethnicity reached remission more often than other ethnicities (P = 0.03-0.0008). Patients treated in high-income countries showed a higher percentage of complete remission at 12 and 24 months (P = 0.002-0.000001). CONCLUSION: The rate of children and adolescents with LN achieving remission varied hugely with the definition used. Our results give important information for long-awaited treatment studies in children and young people.

Clinical significance of interleukin-18 for the diagnosis and prediction of disease course in systemic juvenile idiopathic arthritis.

OBJECTIVE: To investigate the clinical significance of serum IL-18 levels for the diagnosis of systemic JIA (s-JIA) and to predict the disease course of s-JIA. METHODS: Overall, 116 patients with s-JIA, 151 with other diseases and 20 healthy controls were analysed. Serum IL-18 levels were measured longitudinally in 41 patients with s-JIA from active phase through remission phase. Serum IL-18 levels were quantified via enzyme-linked immunosorbent assay and the results were compared with clinical features and the disease course of s-JIA. RESULTS: The serum IL-18 level cut-off value for differentiation of s-JIA from other diseases was 4800 pg/ml. In patients with a monocyclic course, serum IL-18 levels steadily decreased during the inactive phase and low levels were sustained during remission. In contrast, in patients with a chronic course, elevated serum IL-18 levels were sustained even during the inactive phase. In patients with a polycyclic course, serum IL-18 levels were elevated during disease flares and normalized during the inactive phase. The serum IL-18 level cut-off value for diagnosis of remission in s-JIA was 595 pg/ml. CONCLUSION: Serum IL-18 levels of >4800 pg/ml may be useful for differentiating between s-JIA and other diseases. Monitoring of serum IL-18 levels might be useful for predicting the disease course and assessing remission in s-JIA.

Efficacy of hepatitis B vaccination in children with rheumatic diseases.

BACKGROUND: Vaccination to prevent hepatitis B (HB) virus infection is important for children undergoing immunosuppressive treatment. Information on the efficacy of HB vaccination in children with rheumatic diseases undergoing immunosuppressive therapy is scarce. METHODS: Children with rheumatic diseases administered HB vaccine during immunosuppressive treatment between May 2013 and September 2016 were enrolled. Patients were vaccinated three times (primary series). Those who remained seronegative after the primary series received a secondary series of vaccinations. Patient baseline characteristics and treatment details from the medical records were retrospectively investigated. The proportion of patients that was seropositive for HB virus antibody after primary-and secondary series of vaccinations was calculated. Associations between immunosuppressants and serostatus were evaluated. RESULTS: Fifteen of 26 patients (58%) produced anti-hepatitis B surface antibody (anti-HBs) after the primary vaccinations. Eight of 10 patients (80%) taking methotrexate and 3 of 11 (27%) taking mycophenolate mofetil (MMF) were seropositive. Multivariate analysis adjusted for dosage of prednisolone per body weight. Multivariate analysis showed MMF was a factor impeding seroconversion (odds ratio 0.093, 95% confidence interval 0.014-0.615). In six of seven patients (86%) who received a secondary series of vaccinations, anti-HBs were produced. CONCLUSIONS: MMF may impede seroconversion after a primary series of HB vaccinations, thus requiring secondary series of vaccinations in pediatric patients with a rheumatic disease undergoing immunosuppressive therapy.

[The Strength of the Sense of Shame of the Aged in Care Scenes: Comparison Between Whether or not There is Anyone Else Around Them].

Medical staff in a hospital or nursing facility should take care of aged individuals with dignity and respect. We conducted a survey on aged individuals to derive under what care circumstances they had a sense of shame, using 12 illustrations, drawn by ourselves, which were common daily care scenes where nurses and patients meet. This survey was conducted at 4 care facilities in A prefecture, Japan. The number of surveyed persons was 43, with the following exclusion criteria: over 60 years old, more than third level of care needed, and non suspected of having dementia. We got the following results from the answers of 41 persons: 1. When elder persons are surrounded by people other than the care staff, they feel more of a sense of shame than when alone; 2. They feel more sense of shame when they use a wheelchair than when they use crutches; 3. They do not feel much shame when they get a bed-bath, even if other persons are there; and 4. Male patients feel more shame than females when they meet their family. These results suggest that elderly patients feel a stronger sense of shame when they are seen by others than when they are seen by care staff. The result 2 suggests that the use of a wheelchair exposes their physical weakness to others. Males feel a stronger sense of shame when they show a weakness in their gender role. We conclude that the sense of shame of aged individuals in daily life scenes in a care facility depends on their gender and whether or not they are surrounded by other persons.

Efficacy and safety of canakinumab in systemic juvenile idiopathic arthritis: 48-week results from an open-label phase III study in Japanese patients.

OBJECTIVES: To assess the efficacy and safety of canakinumab in Japanese patients with systemic juvenile idiopathic arthritis (sJIA). METHODS: This was an open-label, single-arm active treatment study. sJIA patients, aged ≥2 to <20 years, were administered canakinumab 4 mg/kg every 4 weeks for ≤48 weeks. The co-primary endpoints were the proportion of patients who achieved an adapted American College of Rheumatology pediatric (ACR pedi) 30 criteria at week 8, and the proportion of patients who successfully tapered corticosteroids at week 28. Herein, the efficacy and safety results up to 48 weeks are reported. RESULTS: Of the 19 patients enrolled, 15 (78.9%) had previously used tocilizumab. All patients achieved ACR pedi 30 at week 8 and 73.7% (14/19) successfully tapered corticosteroids at week 28. At week 48, ACR pedi 50/70/90/100 responses were achieved by 100.0%/100.0%/87.5%/68.8% of patients. The most common adverse events (AEs) were infections (271.6 patient-years), 42.1% (8/19) patients had serious AEs. Two potential cases of macrophage activation syndrome were identified. No deaths were reported. CONCLUSION: Canakinumab was efficacious in Japanese patients with sJIA and was associated with substantial corticosteroid dose reduction in the majority of patients. The safety profile of canakinumab was consistent with that observed from previous studies. CLINICALTRIALS.GOV (IDENTIFIER: NCT02396212).

Safety and effectiveness of adalimumab in Japanese patients with juvenile idiopathic arthritis: Results from a real-world postmarketing study.

OBJECTIVES: This study was conducted to assess the real-world safety and effectiveness of adalimumab in patients with juvenile idiopathic arthritis (JIA). METHODS: In this all-case, postmarketing surveillance study (NCT01412021) conducted in Japan, patients receiving adalimumab for JIA affecting multiple joints were observed for 24 weeks. The safety (adverse drug reactions [ADRs]/serious ADRs) and effectiveness (4-variable Disease Activity Score in 28 joints using erythrocyte sedimentation rate [DAS28-4/ESR] remission rate) were assessed. RESULTS: In the safety population (n = 356), 90.3% (65/72; weight, ≥15-<30 kg) of patients received adalimumab 20 mg every 2 weeks (q2w) and 98.3% (236/240; weight ≥30 kg) received 40 mg q2w. Incidence of ADRs and serious ADRs was 29.8% (106/356) and 3.4% (12/356), respectively. Incidence of ADRs was significantly higher in patients aged <15 years vs. ≥15 years (34.6% vs. 21.1%, p = .0072), those with comorbidities vs. without (38.3% vs. 25.7%, p = .0155), and those receiving dose <40 mg q2w vs. ≥40 mg q2w (38.8% vs. 26.9%, p = .0418). DAS28-4/ESR remission rate improved from 21.7% (36/166) at baseline to 74.7% (112/150) at week 24. CONCLUSIONS: Adalimumab was well tolerated and had acceptable safety and effectiveness in patients with JIA in the real-world setting.

Clinical practice guidance for Sjögren's syndrome in pediatric patients (2018) - summarized and updated.

There are a considerable number of pediatric patients with Sjögren's syndrome (SS); however, SS is generally considered rare among children. Pediatric patients with SS report fewer sicca symptoms; therefore, many are under-diagnosed and cannot access appropriate medical management. Therefore, we propose a newly developed guidance for the diagnosis, treatment, and management of pediatric SS, including epidemiology, clinical features, and diagnostic examination methodology. The aim of this guidance was to standardize the medical care of pediatric SS in Japan, and we published the Japanese version by YODOSHA in 2018. This article is the English version, which is summarized and updated. This guidance will need to be revised in the near future as additional clinical data become available.

Clinical characteristics and treatment of 50 cases of Blau syndrome in Japan confirmed by genetic analysis of the NOD2 mutation.

OBJECTIVES: To collect clinical information and NOD2 mutation data on patients with Blau syndrome and to evaluate their prognosis. METHODS: Fifty patients with NOD2 mutations were analysed. The activity of each NOD2 mutant was evaluated in HEK293 cells by reporter assay. Clinical information was collected from medical records through the attending physicians. RESULTS: The study population comprised 26 males and 24 females aged 0-61 years. Thirty-two cases were sporadic, and 18 were familial from 9 unrelated families. Fifteen different mutations in NOD2 were identified, including 2 novel mutations (p.W490S and D512V); all showed spontaneous nuclear factor kappa B activation, and the most common mutation was p.R334W. Twenty-six patients had fever at relatively early timepoints in the disease course. Forty-three of 47 patients had a skin rash. The onset of disease in 9 patients was recognised after BCG vaccination. Forty-five of 49 patients had joint lesions. Thirty-eight of 50 patients had ocular symptoms, 7 of which resulted in blindness. After the diagnosis of Blau syndrome, 26 patients were treated with biologics; all were antitumour necrosis factor agents. Only 3 patients were treated with biologics alone; the others received a biologic in combination with methotrexate and/or prednisolone. None of the patients who became blind received biologic treatment. CONCLUSIONS: In patients with Blau syndrome, severe joint contractures and blindness may occur if diagnosis and appropriate treatment are delayed. Early treatment with a biologic agent may improve the prognosis.

Clinical practice guidance for juvenile dermatomyositis (JDM) 2018-Update.

Juvenile dermatomyositis is the most common type of juvenile idiopathic inflammatory myopathy mainly affecting the skin and proximal muscles. We have published the Japanese version of 'Clinical practice guidance for juvenile dermatomyositis (JDM) 2018 'consisting of a review of articles in the field and evidence-informed consensus-based experts' opinion on the treatment strategy in collaboration with The Pediatric Rheumatology Association of Japan and The Japan College of Rheumatology under the financial support by 'Research on rare and intractable diseases, Health and Labor Sciences Research Grants'. This article is a digest version of the Japanese guidance.

[Nursing Care Students' Image of Shame -Comparison Between First and Second Year Nursing Students].

It is not easy for nurses to estimate a patient's degree of shame, as the sense of shame depends on each person's personality, but nurses are requested to evaluate it as correctly as possible and to reduce the patient's mental load. We presume that most of the sense of shame is generated by body defects or disadvantages recognized by the patient. In this study, we tried to measure the degree of shame and to improve the basic nursing curriculum, depending on students' school year, under the assumption of what cases the nurses would frequently meet in a hospital. We prepared 13 figures that show common cases in hospitals. In these figures: 1) 6 figures show cases in which a nurse touched a patient's body; 2) 3 figures show common daily life; and 3) 4 figures show cases in which there are other people around the patient. A questionnaire was given to the first and second year students in A Nursing University, and we allocated scores of 1 to 10: 1 is "no-shame", and 10 is "very much shame". The students answered that patients must feel shame when: 1) they take off their clothes, 2) they show their disability to another person even without taking their clothes off, and 3) having people other than medical staff around them. In the results, as 2) appeared more strongly in the second year students than in the first, we thought that the second year students could surmise a patient's position in a hospital through the effect of the nursing education.

Risk factors for hypersensitivity reactions to tocilizumab introduction in systemic juvenile idiopathic arthritis.

OBJECTIVES: The objective of this study is to identify risk factors for hypersensitivity reaction (HSR) to tocilizumab (TCZ) in systemic juvenile idiopathic arthritis (sJIA). METHODS: Clinical records of 40 patients with sJIA administered TCZ at one center were retrospectively reviewed. Patients were divided into HSR or non-HSR groups depending on the presence of HSR between the first and third TCZ administrations; clinical and laboratory assessments, including serum cytokine profile, were compared. RESULTS: Five patients displayed HSR following the third TCZ administration. They were significantly younger, shorter, and lighter, with a higher peak body temperature than non-HSR patients following the third administration. Their serum C-reactive protein (CRP) level was undetectable following the first administration but detectable by the third administration. Before the third administration, the white blood cell counts and serum levels of CRP and sTNFRII were significantly higher in the HSR group than in the non-HSR group. The serum levels of interleukin-18 and -6 before the third TCZ administration were higher and lower than those before the first administration in the HSR and non-HSR groups, respectively. CONCLUSION: Patients with sJIA having a younger age, shorter stature, and lighter weight and those showing increased disease activity in the early period of TCZ administration may be at higher risk of TCZ-induced HSR.
