Novel susceptibility loci for steroid-associated osteonecrosis of the femoral head in systemic lupus erythematosus.

Osteonecrosis of the femoral head (ONFH) involves necrosis of bone and bone marrow of the femoral head caused by ischemia with unknown etiology. Previous genetic studies on ONFH failed to produce consistent results, presumably because ONFH has various causes with different genetic backgrounds and the underlying diseases confounded the associations. Steroid-associated ONFH (S-ONFH) accounts for one-half of all ONFH, and systemic lupus erythematosus (SLE) is a representative disease underlying S-ONFH. We performed a genome-wide association study (GWAS) to identify genetic risk factors for S-ONFH in patients with SLE. We conducted a two-staged GWAS on 636 SLE patients with S-ONFH and 95 588 non-SLE controls. Among the novel loci identified, we determined S-ONFH-specific loci by comparing allele frequencies between SLE patients without S-ONFH and non-SLE controls. We also used Korean datasets comprising 148 S-ONFH cases and 37 015 controls to assess overall significance. We evaluated the functional annotations of significant variants by in silico analyses. The Japanese GWAS identified 4 significant loci together with 12 known SLE susceptibility loci. The four significant variants showed comparable effect sizes on S-ONFH compared with SLE controls and non-SLE controls. Three of the four loci, MIR4293/MIR1265 [odds ratio (OR) = 1.99, P-value = 1.1 × 10-9)], TRIM49/NAALAD2 (OR = 1.65, P-value = 4.8 × 10-8) and MYO16 (OR = 3.91, P-value = 4.9 × 10-10), showed significant associations in the meta-analysis with Korean datasets. Bioinformatics analyses identified MIR4293, NAALAD2 and MYO16 as candidate causal genes. MIR4293 regulates a PPARG-related adipogenesis pathway relevant to S-ONFH. We identified three novel susceptibility loci for S-ONFH in SLE.

Longitudinal evaluation of adverse events due to steroid use in primary immune thrombocytopenia: A population-based study.

This study aimed to investigate the association between the steroid use patterns and the risk of AEs in patients with primary immune thrombocytopenia (ITP). A total of 2691 newly diagnosed adults with ITP between 2011 and 2018 were identified from the National Health Insurance Research Database in Taiwan, and the date of first steroid use was defined as the index date. Post-index steroid use was calculated on a 90-day basis as a time-dependent variable and categorized by the average prednisolone-equivalent daily dose (<10 mg vs. ≥10 mg) and intensity (medication possession ratio <80% vs. ≥80%). Patients were followed up for 1 year from the index date for acute AE events, while chronic AEs were assessed until death, or end of 2019. Compared to patients with low-dose+low-intensity steroid use, those with high-dose+high-intensity steroid use were associated with a higher risk of acute AE (adjusted incident rate ratio [aIRR]: 1.57, 95% confidence interval [CI]: 1.38-1.78, p < 0.01) and chronic AE (aIRR: 1.26, 95% CI: 1.08-1.47, p < 0.01). Metabolic/endocrine and ophthalmologic disorders demonstrated the strongest correlation with a high dose and intensity. The joint effect of steroid dose and intensity was observed in patients with ITP, and the findings suggest that steroids should be used carefully.

Feasibility of steroid-free tacrolimus-basiliximab immunosuppression in pediatric liver transplantation and predictors for steroid requirement.

Avoidance of steroids in pediatric liver transplantation may reduce toxicity and morbidity. The aim of this study was to analyze the feasibility of a steroid-free tacrolimus-basiliximab immunosuppression scheme, the risk factors associated with steroid requirement, and safety parameters. Patients who underwent liver transplantation for biliary atresia between 2011 and 2019 were included and followed for 6 months after transplantation. Immunosuppression consisted of tacrolimus-based treatment with basiliximab induction. Steroid-free survival was estimated, and risk factors for steroid requirement were evaluated using multivariate Cox regression analysis. A total of 76 patients were included, of whom 42 (55.3%) required steroids (>14 d) due to biopsy-proven acute rejection (47.6%, n = 20), instability in liver function tests (35.7%, n = 15), tacrolimus-related adverse drug reactions (14.3%, n = 6), or other reasons (bronchospasm episode, n = 1). Steroid-free survival was 45.9% (95% CI, 35.9-58.8). Independent factors associated with steroid requirement included tortuosity in tacrolimus trough levels (≥1.76 vs. <1.76: HR 5.8, 95% CI, 2.6-12.7; p < 0.001) and mean tacrolimus trough levels (≥ 6.4 ng/mL vs. < 6.4 ng/mL: HR 0.4, 95% CI, 0.2-0.7; p = 0.002). The rate of bacterial and viral infections was comparable between patients with and without steroids, although in the former group, cytomegalovirus infection developed earlier ( p = 0.03). Patients receiving steroids had higher total cholesterol, LDL, and HDL levels ( p < 0.05) during follow-up, but no changes in the height Z-score were observed 1 year after transplantation. Basiliximab induction in combination with tacrolimus-based treatment avoided steroid requirements in 45% of the patients. Tacrolimus variability and trough levels below 6.4 ng/mL independently increased the risk of steroid requirement. Further efforts should be focused on personalizing immunosuppressive treatment.

miR-486-5p Attenuates Steroid-Induced Adipogenesis and Osteonecrosis of the Femoral Head Via TBX2/P21 Axis.

Enhanced adipogenic differentiation of mesenchymal stem cells (MSCs) is considered as a major risk factor for steroid-induced osteonecrosis of the femoral head (SOFNH). The role of microRNAs during this process has sparked interest. miR-486-5p expression was down-regulated significantly in femoral head bone tissues of both SONFH patients and rat models. The purpose of this study was to reveal the role of miR-486-5p on MSCs adipogenesis and SONFH progression. The present study showed that miR-486-5p could significantly inhibit adipogenesis of 3T3-L1 cells by suppressing mitotic clonal expansion (MCE). And upregulated expression of P21, which was caused by miR-486-5p mediated TBX2 decrease, was responsible for inhibited MCE. Further, miR-486-5p was demonstrated to effectively inhibit steroid-induced fat formation in the femoral head and prevented SONFH progression in a rat model. Considering the potent effects of miR-486-5p on attenuating adipogenesis, it seems to be a promising target for the treatment of SONFH.

Relapse and side effects of steroid therapy beyond 3 years in autoimmune pancreatitis: A multicenter retrospective study.

BACKGROUND: The impact of extended steroid administration on patients with autoimmune pancreatitis after a 3-year maintenance period remains poorly understood. This study analyzed the advantage and disadvantage of continuing steroid therapy beyond 3 years. METHODS: In this retrospective multicenter study across 17 institutions, patients who successfully completed 3 years of maintenance therapy without experiencing relapse were categorized into two groups: the maintenance therapy discontinuation group, who discontinued steroid therapy after the initial 3-year period, and maintenance therapy continuation group, who continued steroid therapy beyond 3 years. The cumulative relapse rate after 3 years of maintenance therapy was the primary outcome. Relapse predictors were compared using the Gray test for cumulative relapse incidence by specific factor. RESULTS: Of 211 patients, 105 experienced no relapse during the 3-year maintenance therapy and were divided into two groups: 69 in the maintenance therapy discontinuation group and 36 in the maintenance therapy continuation group. The relapse rate was lower in the maintenance therapy continuation group than in the maintenance therapy discontinuation group (P = 0.035). Predictors of relapse after 3 years included cessation of maintenance therapy (hazard ratio [HR] = 3.76; 95 % confidence interval [CI] = 1.07-13.3, P = 0.040) and renal involvement (HR = 2.88; 95 % CI = 1.04-7.99, P = 0.042). The maintenance therapy continuation group showed a significantly higher prevalence of macrovascular complications, compared with the maintenance therapy discontinuation group (P = 0.005). CONCLUSIONS: Cessation of steroid maintenance therapy and renal involvement were predictors of relapse after 3 years of maintenance therapy. However, the long-term use of steroids may increase the risk of macrovascular complications.

Neurodevelopment in Term Infants with Normal Birthweight following Postnatal Systemic Steroid Exposure.

INTRODUCTION: Studies investigating the potential impact of systemic steroid exposure during early infancy on neurological development in full-term infants with normal birth weight are lacking. METHODS: This population-based administrative cohort study used data of national health insurance and a health-screening program for infants and children and included full-term infants who were born in Korea between 2008 and 2012 with normal birth weight and did not have any specific perinatal or neurodevelopmental diseases. The prescription of systemic steroids within the first 3 months of age was mainly considered. The neurological development of children was assessed using the Korean Development Screening Test (K-DST) at 6 years of age. To balance the baseline characteristics of the control and exposed groups, stabilized inverse probability of treatment weighting with trimming was performed in the main cohort. Ordinal logistic regression was used to assess the association between systemic steroid exposure and unfavorable results in the K-DST. RESULTS: The control and exposure groups had 246,168 and 5,083 children, respectively. The K-DST suggested unfavorable results in 8.1% and 8.6% children in the control and exposure groups, respectively (weighted odds ratio, 95% confidence interval, 1.03, 0.93-1.14). When each domain of the K-DST was considered separately, the risk of unfavorable results in the exposed group was not significantly different from that in the control group. CONCLUSIONS: No significant association was observed between exposure to systemic steroids during early infancy and neurodevelopmental impairment at 6 years of age.

Adult survivors of childhood-onset steroid-dependent and steroid-resistant nephrotic syndrome treated with cyclosporine: a long-term single-center experience.

BACKGROUND: Although evidence has confirmed that cyclosporine (CS) is efficacious against childhood-onset steroid-dependent and steroid-resistant nephrotic syndrome (SD/SRNS), some patients may continue to relapse during adulthood. However, predictive factors for adult active disease and kidney complications, such as chronic kidney disease (CKD) and hypertension, in this cohort remain unknown. METHODS: We conducted a retrospective study on the long-term outcomes of 81 young adults with childhood-onset SD/SRNS treated with CS. The primary endpoint was the probability of active disease into adulthood. The secondary endpoint was the probability of developing kidney complications. RESULTS: At the last follow-up (median age, 23.2 years; median disease duration, 15.8 years), 44 adult patients (54%) continued to have active disease, whereas 16 patients developed CKD or hypertension, respectively. The proportion of patients developing kidney complications was similar between the active disease and long-term remission groups. Young age at NS onset and history of relapse during the initial CS (median, 31 months) were independent predictive factors for active disease. Acute kidney injury at NS onset, focal segmental glomerulosclerosis, and irreversible CS nephrotoxicity were identified as risk factors for the development of CKD, whereas older age was identified as a risk factor for the development of CKD and hypertension. CONCLUSIONS: More than 50% of adult survivors treated with CS continued to have active disease, and each 20% developed CKD or hypertension. A long-term follow-up is necessary for patients with SD/SRNS to identify the development of kidney complications later in adulthood that can be attributed to prior disease and CS treatment in childhood, irrespective of disease activity. A higher resolution version of the Graphical abstract is available as Supplementary information.

Neurodevelopment at 24 months corrected age in extremely preterm infants treated with dexamethasone alternatives during the late postnatal period: a cohort study.

The administration of dexamethasone has been associated with suboptimal neurodevelopment. We aimed to compare the development of extremely premature infants treated or not with alternatives to dexamethasone: betamethasone, hydrocortisone hemisuccinate. This retrospective cohort study included infants born before 29 weeks of gestational age, treated or not with late (day ≥ 7) postnatal steroids (betamethasone, hydrocortisone hemisuccinate). The neurodevelopment outcome was evaluated at 24 months corrected age, after adjustment on comorbidities of extreme prematurity. In order to analyse their overall development, data about growth and respiratory outcomes were collected. Among the 192 infants included, 59 (30.7%) received postnatal steroids. Suboptimal neurodevelopment concerned 37/59 (62.7%) postnatal steroid-treated and 43/133 (38.1%; p = 0.002) untreated infants. However, in multivariable analysis, only severe neonatal morbidity (p = 0.007) and male gender (p = 0.027) were associated with suboptimal neurodevelopment outcome at 24 months.  Conclusions: Betamethasone or hydrocortisone hemisuccinate treatment was not an independent risk for suboptimal neurological development, growth and respiratory outcomes assessed at 24 months corrected age in extremely premature infants.  Registration number: The study was registered on the ClinicalTrials.gov register: NCT05055193. What is Known: • Late postnatal steroids are used to treat bronchopulmonary dysplasia • Meta-analyses warned against the neurological risk of dexamethasone use during neonatal period. Early or late hydrocortisone hemisuccinate has been evaluated in multiple studies, none of which have reported an adverse effect on neurodevelopment at least to 2 years. Data about the use of betamethasone are scarce. What is New: • The risk of suboptimal neurodevelopment was higher among extremely premature infants who received postnatal steroids when compared to those who did not. • Betamethasone and hydrocortisone hemisuccinate treatment was not an independent risk factor for suboptimal neurodevelopment at 24 months corrected age.

Rituximab in combination with cyclosporine and steroid pulse therapy for childhood-onset multidrug-resistant nephrotic syndrome: a multicenter single-arm clinical trial (JSKDC11 trial).

BACKGROUND: Only 80% of children with idiopathic nephrotic syndrome respond well to glucocorticoid therapy. Multidrug-resistant nephrotic syndrome (MRNS) is associated with a poor kidney prognosis. Several retrospective studies have identified rituximab as an effective treatment for MRNS; however, prospective studies are required to assess its efficacy and safety. METHODS: We conducted a multicenter, non-blinded, single-arm trial to investigate the efficacy and safety of rituximab in patients with childhood-onset MRNS who were resistant to cyclosporine and more than three courses of steroid pulse therapy. The enrolled patients received four 375 mg/m2 doses of rituximab in combination with baseline cyclosporine and steroid pulse therapy. The primary endpoint was a > 50% reduction in the urinary protein/creatinine ratio from baseline on day 169. Complete and partial remissions were also evaluated. RESULTS: Six patients with childhood-onset MRNS were enrolled. All patients were negative for pathogenic variants of podocyte-related genes. On day 169, five patients (83.3%) showed a > 50% reduction in the urinary protein/creatinine ratio, two patients showed partial remission, and two patients showed complete remission. No deaths occurred and severe adverse events occurred in two patients (infection in one patient and acute kidney injury in one patient). Three patients needed treatment for moderate-to-severe infection. CONCLUSIONS: The study treatment effectively reduced the urinary protein/creatinine ratio in patients with childhood-onset MRNS. The adverse events in this study were within the expected range; however, attention should be paid to the occurrence of infections.

Steroid use in measles: A retrospective cohort study during the 2017 outbreak in tertiary referral center, Rome and Latina, Italy.

INTRODUCTION: Since early January 2017, a new measles outbreak in Italy has been observed. The aim of the study was to compare features between adults and children measles cases and evaluate the effect of steroid treatment on the above parameters. METHODS: A retrospective multicenter, descriptive study was performed. We analyzed all patients admitted to the Department of Public Health and Infectious Diseases, Sapienza University, Rome and Latina, from January 2017 to December 2017 and discharged with diagnosis of measles. RESULTS: We identified 113 patients discharged with the diagnosis of measles infection cases of which 59 adults and 54 children (≤16 years). In adult population 32 patients (54 %) were males, with a median age of 30.5 years old and all unvaccinated (100 %). Keratoconjunctivitis 30 (50 %) was the most frequent complication. In pediatric population 27 (50 %) patients were males, with a median age of 3 years old. Information on measles vaccination status was available for only 21 (38.8 %) of cases. Keratoconjunctivitis 40 (74 %) was the most frequent complication. Analyzing the differences between adult and pediatric patients we found that children were significantly more likely to have keratoconjunctivitis and diarrhea as complications than adults in which the rate of thrombocytopenia and hepatitis was highest. Thirty-nine adult subjects (66 %) have been treated with systemic corticosteroids. CONCLUSIONS: Pediatric patients differ from adults in complications and liver involvement. Regarding steroids use, although there is no clear indication of steroid use during measles, there is no evidence of a worse outcome in our cases series.

Characteristics of the Online Market for Anabolic-Androgenic Steroids in Central Asia: A Netnographic Analysis.

Background: With the online proliferation of illegal substances, the Internet offers a wide variety of information on the acquisition and intake of anabolic-androgenic steroids (AAS) and other performance and image enhancing drugs. This study focuses on investigating the characteristics of the online AAS market in Central Asia. OBJECTIVES: The primary objectives of this study were to investigate the accessibility and features of the online market for AAS in Central Asia. To achieve this, we employed a netnographic approach for a systematic exploration of websites advertising and selling AAS. The study aimed to conduct a comprehensive analysis of several key aspects, including the variety of AAS products offered, the quality of health advice provided the level of product availability, the procedures involved in making purchases, and the pricing structures within this market. RESULTS: Twenty-one websites supplying AAS in Central Asia met our inclusion criteria. Using content analysis, data were gathered on AAS offerings, quality of health advice provided, availability, purchase process, and prices. Data were synthesized using descriptive statistics. Results indicate that AAS are easily accessible for purchase without valid medical prescription in the Central Asia online market. Most websites advertised the aesthetic and ergogenic benefits of AAS use without indicating the potential complications and adverse effects. CONCLUSIONS: Public health efforts to mitigate AAS use in Central Asia should consider both the online accessibility of AAS and the lack of accompanying information on potential complications as well as adverse effects associated with their use. Efforts must be intensified to curtail the proliferation of AAS and related misleading information on the Central Asian online market.

[Transcriptome data mining combined with clinical and animal experiments for identification of syndrome element marker genes during entire course of steroid-induced osteonecrosis of femoral head].

A research strategy combining transcriptome data mining and experimental verification was adopted to identify the marker genes characterizing the syndrome elements of phlegm, stasis, and deficiency in steroid-induced osteonecrosis of the femoral head(SONFH). Firstly, the common differentially expressed gene sets of SONFH with the syndromes of phlegm-stasis obstructing collaterals, vessel obstruction, and liver-kidney deficiency were obtained from the clinical transcriptomic analysis of a previous study. The differential expression trend analysis and functional gene mining were then employed to predict the candidate marker gene sets representing phlegm, stasis, and deficiency. The whole blood samples from SONFH patients, whole blood samples from SONFH rats, and affected femoral head tissue samples were collected for qPCR, which aimed to determine the expression levels of the candidate marker genes mentioned above. Furthermore, the receiver operating characteristic curve(ROC) was established to objectively evaluate the syndrome differentiation effectiveness of the candidate marker genes mentioned above. The transcriptome data analysis results showed that the candidate marker genes for phlegm was ELOVL fatty acid elongase 6(ELOVL6), and those for stasis were ankyrin 1(ANK1), glycophorin A/B(GYPA/B), and Rh-associated glycoprotein(RHAG). The candidate marker genes for deficiency were solute carrier family 2 member 1(SLC2A1) and stomatin(STOM). The qPCR results showed that compared with that in the non-SONFH group, ELOVL6 had the lowest expression level in the peripheral blood of the SONFH patients with the syndrome of phlegm-stasis obstructing collaterals(P<0.05). Compared with that in the normal control group, ELOVL6 had the lowest expression level in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 4 weeks(P<0.01), and it showed better syndrome differentiation effectiveness of rats modeled for 4 weeks(AUC=0.850, P=0.006) than at other modeling time points(8, 12, 16, and 21 weeks, AUC of 0.689, 0.766, 0.588, and 0.662, respectively). Compared with that in the non-SONFH group, the expression levels of ANK1, GYPA, and RHAG were the lowest in the peripheral blood of SONFH patients with the vessel obstruction syndrome(P<0.05). The expression levels of the three genes were the lowest in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 12 weeks(P<0.05, P<0.01), and their syndrome differentiation effectiveness in the rats modeled for 12 weeks(GYPA: AUC=0.861, P=0.012; ANK1: AUC=0.855, P=0.006; RHAG: AUC=0.854, P=0.009) was superior to that for 4, 8, 16, and 21 weeks(GYPA: AUC=0.646, 0.573, 0.691, and 0.617, respectively; ANK: AUC1=0.630, 0.658, 0.657, and 0.585, respectively; RHAG: AUC=0.592, 0.511, 0.515, and 0.536, respectively). Compared with the non-SONFH group, both SLC2A1 and STOM had the lowest expression levels in the peripheral blood of patients with the syndrome of liver and kidney deficiency(P<0.05). Compared with the normal control group, their expression levels were the lowest in the peripheral blood and affected femoral head tissue of SONFH rats modeled for 21 weeks(P<0.05, except STOM in the peripheral blood of rats). Moreover, the syndrome differentiation effectiveness of SLC2A1 in the rats modeled for 21 weeks(AUC=0.806, P=0.009) was superior to that for 4, 8, 12, and 16 weeks(AUC=0.520, 0.580, 0.741, 0.774, respectively), and STOM was meaningless in syndrome differentiation. In summary, the candidate marker gene for phlegm in SONFH is ELOVL6; the candidate marker genes for stasis are GYPA, RHAG, and ANK1; the candidate marker gene for deficiency is SLC2A1. The results help to reveal the biological connotations of phlegm, stasis, and deficiency in SONFH at the genetic level.

[Pouchitis showed complete response to ustekinumab].

Pouchitis is the most common long-term complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis. Although several agents, including probiotics, steroids, and immunomodulators, have been used, the treatment of pouchitis remains challenging. Owing to the proven efficacy of biological therapy in inflammatory bowel disease, there is now growing evidence suggesting the potential benefits of biological therapy in refractory pouchitis. Here, we report the case of a 64-year-old woman with pouchitis due to ulcerative colitis who was successfully treated with ustekinumab (UST). The patient developed ulcerative pancolitis at the age of 35. Total colectomy and IPAA with J-pouch anastomosis were performed when the patient was 47 years old. Ileotomy closure was performed 6 months later. Postoperatively, the patient developed steroid-dependent pouchitis. Three years later, she developed steroid-induced diabetes. The patient has been taking 3mg of steroid for 20 years;therefore, her lifetime total steroid dose was 21g. The patient had over 20 episodes of bloody diarrhea a day. The last pouchoscopy in 20XX-9 revealed inflammatory stenosis with deep ulcerations of the afferent limb just before the ileoanal pouch junction. In July 20XX, when we took over her treatment, the policy of treatment was to withdraw her from steroids. Pouchoscopy revealed a widened but still tight afferent limb through which the scope could easily pass, and the ileoanal pouch still showed erosive ileitis without ulcers. Thiopurine administration and steroid tapering were initiated. Steroid tapering increased the erythrocyte sedimentation rate (ESR). As ESR increased, her arthritis exacerbated. Six months after the end of steroid administration, the patient consented to UST treatment. On April 20XX+1, the patient received her first 260-mg UST infusion. At this point, she experienced 14-15 episodes of muddy bloody stools. She had no abdominal pain;however, she experienced shoulder pain. Gradually, UST affected both pouchitis and arthritis. UST treatment was continued at 90mg subcutaneously every 12 weeks without abdominal pain recurrence. Eight months after the first UST infusion, nonsteroidal anti-inflammatory drugs were no longer necessary for shoulder pain. Follow-up pouchoscopy performed 14 months after UST optimization revealed a normal afferent limb without ulcerations in either segment. Pouchitis remission was maintained for over 2 years.

Effect of Adjuvant Steroid Therapy in Type 3 Biliary Atresia: A Single-Center, Open-Label, Randomized Controlled Trial.

OBJECTIVE: To evaluate the efficacy and side effects of additional postoperative steroid therapy for type 3 BA versus the current routine care. SUMMARY BACKGROUND DATA: Whether steroid therapy post-Kasai portoen-terostomy improves the outcomes of BA remains controversial. Clinical evidence from 2 randomized trials in the UK and USA do not support the routine use of steroid in the treatment of BA. METHODS: In this open-label randomized controlled trial, patients with type 3 BA were randomized to routine postoperative treatment with or without 10 to 12 weeks of adjuvant steroid treatment. The primary outcome was the postoperative jaundice clearance rate with native liver at 6 months. The secondary outcomes included postoperative jaundice clearance rate at 3, 12, and 24 months, survival with native liver at 12 and 24 months, and SAEs within 3 months. RESULTS: Overall, 200 participants were randomized and allocated into either steroid or control group (n = 100/group). The proportion of participants that are jaundice free without liver transplantation was significantly higher in the steroid group than in the control group at 6 months (54.1% vs 31.0%, P = 0.0015). The native liver survival rate was higher postoperatively in the steroid group than in the control group at 12 (66.3% vs 50.0%, P = 0.02) and 24 (57.1% vs 40.0%, P = 0.02) months. The survival time with native liver was significantly longer in the steroid group than in the control group (median survival, steroid vs control: not reached vs 1.21 years, P = 0.02). There were no significant differences between the 2 groups in the mean occurrence of SAEs within 3 months (steroid vs control: 0.63 vs 0.45, P = 0.20). CONCLUSIONS: Postoperative adjuvant steroid intervention improved bile drainage and survival with native liver in type 3 BA patients, without increasing early-stage SAEs.

An update on corticosteroid treatment for IgA nephropathy.

PURPOSE OF REVIEW: The use of corticosteroids to treat IgA nephropathy (IgAN) has been limited by many controversies related to uncertain benefit and safety concerns. Recent trials have tried to address these limitations. RECENT FINDINGS: After being paused because of an excess of adverse events in the full-dose steroid arm, the TESTING trial compared a reduced dose of methylprednisolone to placebo in patients with IgAN after optimization of supportive therapy. Steroid treatment was associated with a significant reduction in the risk of a 40% decline in estimated glomerular filtration rate (eGFR), kidney failure and kidney death as well as a sustained decrease in proteinuria compared with placebo. Serious adverse events were more frequent with the full dose regimen but less common in the reduced dose regimen. A phase III trial evaluating a new formulation of targeted-release budesonide showed a significant reduction in short-term proteinuria and has resulted in accelerated FDA approval for use in the United States. In a subgroup analysis of DAPA-CKD trial, sodium-glucose transport protein 2 inhibitors reduced the risk of kidney function decline in patients who have completed or are not eligible for immunosuppression. SUMMARY: Both reduced-dose corticosteroids and targeted-release budesonide are new therapeutic options that can be used in patients with high-risk disease. More novel-targeted therapies with a better safety profile are currently under investigations.

Incidence and predictors of infections in patients with advanced non-small cell lung cancer treated with checkpoint inhibitor immunotherapies: A monocentric retrospective cohort study.

Immune checkpoint inhibitors (ICIs) represent the cornerstone of the current treatment of non-small cell lung cancer (NSCLC). However, the occurrence of concomitant infections might hamper success. All consecutive patients with advanced NSCLC who started ICIs as a first- or second-line therapy from January 1, 2017 to June 30, 2020 were retrospectively evaluated. The occurrence of infectious events during ICIs was correlated with clinical characteristics, including previous Cytotoxic Chemotherapy (CC), occurrence of immune-related-adverse-events (irAEs). A total of 211 patients were included, 46 (22%) females, with a median (q1-q3) age of 69 (62-76) years. Overall, 85 patients (40%) received ICIs as a first treatment line and 126 (60%) as a second line; 40 patients (19%) had at least one infection during ICIs, and 17 (8%) more than one. Notably, autoimmune diseases (P < .005), neutropenia (P = .001) or infections during previous CC (P = .001), irAEs (P = .006), or steroid therapy for irAEs (P < .001) were associated with infection development. By multivariate Cox-regression, autoimmune diseases (aHR = 6.27; 95%CI = 2.38-16.48; P < .001) and steroid therapy for irAEs (aHR = 2.65; 95%CI = 1.27-5.52; P < .009) were associated with a higher risk of infection during ICIs. Interestingly, autoimmune diseases were confirmed as risk factors in patients treated with ICIs as a first line, while previous infections were the only independent predictor of infections in patients treated with ICIs as a second line. Patients with NSCLC treated with ICIs with concurrent autoimmune disease, receiving steroid therapy for management of irAEs, or having a history of previous infections during CC should be actively monitored for the risk of developing infectious complications.

Management of Steroid-Refractory Gastrointestinal Immune-Related Adverse Events.

BACKGROUND: Immune checkpoint inhibitors (ICIs) cause inflammatory immune-related adverse events (irAEs), which are often effectively managed with steroids. Less is known about the best management of irAEs refractory to steroid treatment. OBJECTIVE: We aimed to assess the efficacy of second-line medications used to treat gastrointestinal (GI) irAEs. METHODS: This study was a single-center, retrospective medical record review of patients who received steroids for an ICI GI irAE and at least one dose of infliximab, vedolizumab, or adalimumab for irAE treatment from March 25, 2011 to September 20, 2019, approved by Yale University's Institutional Review Board. Our primary objective was to assess the efficacy of second-line treatment, measured by the change in the Common Terminology Criteria for Adverse Events Version 5.0 grading system. RESULTS: A total of 39 patients met inclusion criteria. Treatment for steroid-refractory GI irAEs demonstrated a high response rate, with irAE resolution seen in 89.7% of patients. Patients who were specifically initiated on infliximab within 14 days of starting steroids had a higher percent resolution seen in 94.4% of patients. The average time to response, defined as the average days from second-line therapy to reported symptom resolution, was 17 days. CONCLUSION AND RELEVANCE: Steroid-refractory GI irAEs can be managed effectively in most patients with immunosuppressive therapy, such as infliximab. Furthermore, initiating second-line immunosuppressive therapy within 14 days of steroid failure resulted in a higher rate of symptom resolution.

Prevalence of and prognostic factors for Candida superinfection in oral lichen planus and lichenoid reactions: A retrospective cohort study.

BACKGROUND: Oral candidiasis occasionally occurs in patients with oral lichen planus (OLP) or lichenoid reaction (OLR). However, not all patients undergoing corticosteroid therapy develop Candida superinfection. Thus, the identification of prognostic risk factors may help to identify patients at risk of Candida superinfection. METHODS: A retrospective cohort study was conducted to review patients with OLP/OLR who received steroid therapy at a single dental hospital between January 2016 and December 2021. The prevalence of Candida superinfection and prognostic factors were assessed. RESULTS: Eighty-two eligible patients with OLP/OLR were retrospectively reviewed. The overall prevalence of Candida superinfection during the study period was 35.37%; the median time-to-event between initiation of corticosteroid therapy and diagnosis of superinfection was 60 days (interquartile range; 34-296). The ulcerative type of OLP/OLR, number of topical steroid applications, poor oral hygiene, and oral dryness were significantly associated with superinfection (p < 0.05; Fisher's Exact test) and were identified as prognostic factors in univariable risk ratio regression. Multivariable risk ratio regression revealed the ulcerative type of OLP/OLR and number of topical steroid applications were significant prognostic factors for Candida superinfection in patients with OLP/OLR. CONCLUSION: Candida superinfection occurs in approximately one-third of patients with OLP/OLR undergoing corticosteroid therapy. Patients with OLP/OLR should be closely monitored in the first 2 months (60 days; median time to infection) after steroid prescription. The ulcerative type of OLP/OLR and a higher number of topical steroid applications per day may represent prognostic factors to identify patients at risk of Candida superinfection.

IPNA clinical practice recommendations for the diagnosis and management of children with steroid-sensitive nephrotic syndrome.

Idiopathic nephrotic syndrome is the most frequent pediatric glomerular disease, affecting from 1.15 to 16.9 per 100,000 children per year globally. It is characterized by massive proteinuria, hypoalbuminemia, and/or concomitant edema. Approximately 85-90% of patients attain complete remission of proteinuria within 4-6 weeks of treatment with glucocorticoids, and therefore, have steroid-sensitive nephrotic syndrome (SSNS). Among those patients who are steroid sensitive, 70-80% will have at least one relapse during follow-up, and up to 50% of these patients will experience frequent relapses or become dependent on glucocorticoids to maintain remission. The dose and duration of steroid treatment to prolong time between relapses remains a subject of much debate, and patients continue to experience a high prevalence of steroid-related morbidity. Various steroid-sparing immunosuppressive drugs have been used in clinical practice; however, there is marked practice variation in the selection of these drugs and timing of their introduction during the course of the disease. Therefore, international evidence-based clinical practice recommendations (CPRs) are needed to guide clinical practice and reduce practice variation. The International Pediatric Nephrology Association (IPNA) convened a team of experts including pediatric nephrologists, an adult nephrologist, and a patient representative to develop comprehensive CPRs on the diagnosis and management of SSNS in children. After performing a systematic literature review on 12 clinically relevant PICO (Patient or Population covered, Intervention, Comparator, Outcome) questions, recommendations were formulated and formally graded at several virtual consensus meetings. New definitions for treatment outcomes to help guide change of therapy and recommendations for important research questions are given.

Topical and oral steroids for otitis media with effusion (OME) in children.

BACKGROUND: Otitis media with effusion (OME) is an accumulation of fluid in the middle ear cavity, common amongst young children. The fluid may cause hearing loss. Although most episodes of OME in children resolve spontaneously within a few months, when persistent it may lead to behavioural problems and a delay in expressive language skills. Management of OME includes watchful waiting, medical, surgical and other treatments, such as autoinflation. Oral or topical steroids are sometimes used to reduce inflammation in the middle ear. OBJECTIVES: To assess the effects (benefits and harms) of topical and oral steroids for OME in children. SEARCH METHODS: We searched the Cochrane ENT Register, CENTRAL, Ovid MEDLINE, Ovid Embase, Web of Science, ClinicalTrials.gov, ICTRP and additional sources for published and unpublished studies on 20 January 2023. SELECTION CRITERIA: We included randomised controlled trials (RCTs) and quasi-randomised trials in children aged 6 months to 12 years with unilateral or bilateral OME. We included studies that compared topical or oral steroids with either placebo or watchful waiting (no treatment). DATA COLLECTION AND ANALYSIS: We used standard Cochrane methods. Our primary outcomes, determined by a multi-stakeholder prioritisation exercise, were: 1) hearing, 2) OME-specific quality of life and 3) systemic corticosteroid side effects. Secondary outcomes were: 1) presence/persistence of OME, 2) other adverse effects (including local nasal effects), 3) receptive language skills, 4) speech development, 5) cognitive development, 6) psychosocial outcomes, 7) listening skills, 8) generic health-related quality of life, 9) parental stress, 10) vestibular function and 11) episodes of acute otitis media. We used GRADE to assess the certainty of evidence. Although we included all measures of hearing assessment, the proportion of children who returned to normal hearing was our preferred method to assess hearing, due to challenges in interpreting the results of mean hearing thresholds. MAIN RESULTS: We included 26 studies in this review (2770 children). Most studies of oral steroids used prednisolone for 7 to 14 days. Studies of topical (nasal) steroids used various preparations (beclomethasone, fluticasone and mometasone) for between two weeks and three months. All studies had at least some concerns regarding risk of bias. Here we report our primary outcomes and main secondary outcome, at the longest reported follow-up. Oral steroids compared to placebo Oral steroids probably result in little or no difference in the proportion of children with normal hearing after 12 months (69.7% of children with steroids, compared to 61.1% of children receiving placebo, risk ratio (RR) 1.14, 95% confidence interval (CI) 0.97 to 1.33; 1 study, 332 participants; moderate-certainty evidence). There is probably little or no difference in OME-related quality of life (mean difference (MD) in OM8-30 score 0.07, 95% CI -0.2 to 0.34; 1 study, 304 participants; moderate-certainty evidence). Oral steroids may reduce the number of children with persistent OME at 6 to 12 months, but the size of the effect was uncertain (absolute risk reduction ranging from 13.3% to 45%, number needed to treat (NNT) of between 3 and 8; low-certainty evidence). The evidence was very uncertain regarding the risk of systemic corticosteroid side effects, and we were unable to conduct any meta-analysis for this outcome. Oral steroids compared to no treatment Oral steroids may result in little or no difference in the persistence of OME after three to nine months (74.5% children receiving steroids versus 73% of those receiving placebo; RR 1.02, 95% CI 0.89 to 1.17; 2 studies, 258 participants; low-certainty evidence). The evidence on adverse effects was very uncertain. We did not identify any evidence on hearing or disease-related quality of life. Topical (intranasal) steroids compared to placebo We did not identify data on the proportion of children who returned to normal hearing. However, the mean change in hearing threshold after two months was -0.3 dB lower (95% CI -6.05 to 5.45; 1 study, 78 participants; very low-certainty evidence). The evidence suggests that nasal steroids make little or no difference to disease-specific quality of life after nine months (OM8-30 score, MD 0.05 higher, 95% CI -0.36 to 0.46; 1 study, 82 participants; low-certainty evidence). The evidence is very uncertain regarding the effect of nasal steroids on persistence of OME at up to one year. Two studies reported this: one showed a potential benefit for nasal steroids, the other showed a benefit with placebo (2 studies, 206 participants). The evidence was also very uncertain regarding the risk of corticosteroid-related side effects, as we were unable to provide a pooled effect estimate. Topical (intranasal) steroids compared to no treatment We did not identify data on the proportion of children who returned to normal hearing. However, the mean difference in final hearing threshold after four weeks was 1.95 dB lower (95% CI -3.85 to -0.05; 1 study, 168 participants; low-certainty evidence). Nasal steroids may reduce the persistence of OME after eight weeks, but the evidence was very uncertain (58.5% of children receiving steroids, compared to 81.3% of children without treatment, RR 0.72, 95% CI 0.57 to 0.91; 2 studies, 134 participants). We did not identify any evidence on disease-related quality of life or adverse effects. AUTHORS' CONCLUSIONS: Overall, oral steroids may have little effect in the treatment of OME, with little improvement in the number of children with normal hearing and no effect on quality of life. There may be a reduction in the proportion of children with persistent disease after 12 months. However, this benefit may be small and must be weighed against the potential for adverse effects associated with oral steroid use. The evidence for nasal steroids was all low- or very low-certainty. It is therefore less clear if nasal steroids have any impact on hearing, quality of life or persistence of OME. Evidence on adverse effects was very limited. OME is likely to resolve spontaneously for most children. The potential benefit of treatment may therefore be small and should be balanced with the risk of adverse effects. Future studies should aim to determine which children are most likely to benefit from treatment, rather than offering interventions to all children.
