Abstract
Although granulocyte colony-stimulating factor (G-CSF) reduces the incidence, duration, and severity of neutropenia, its prophylactic use for acute myeloid leukemia (AML) remains controversial due to a theoretically increased risk of relapse. The present study investigated the effects of G-CSF as primary prophylaxis for AML with remission induction therapy. A detailed literature search for related studies was performed using PubMed, Ichushi-Web, and the Cochrane Library. Data were independently extracted and assessed by two reviewers. A qualitative analysis of pooled data was conducted, and the risk ratio with corresponding confidence intervals was calculated in the meta-analysis and summarized. Sixteen studies were included in the qualitative analysis, nine of which were examined in the meta-analysis. Although G-CSF significantly shortened the duration of neutropenia, primary prophylaxis with G-CSF did not correlate with infection-related mortality. Moreover, primary prophylaxis with G-CSF did not affect disease progression/recurrence, overall survival, or adverse events, such as musculoskeletal pain. However, evidence to support or discourage the use of G-CSF as primary prophylaxis for adult AML patients with induction therapy remains limited. Therefore, the use of G-CSF as primary prophylaxis can be considered for adult AML patients with remission induction therapy who are at a high risk of infectious complications.

Abstract
BACKGROUND Several international high-volume centers have reported good outcomes after resection of locally advanced pancreatic cancer (LAPC) following chemo(radio)therapy, but it is unclear how this translates to nationwide clinical practice and outcome. This study aims to assess the nationwide use and outcome of resection of LAPC following induction chemo(radio)therapy. PATIENTS AND METHODS A multicenter retrospective study including all patients who underwent resection for LAPC following chemo(radio)therapy in all 16 Dutch pancreatic surgery centers (2014-2020), registered in the mandatory Dutch Pancreatic Cancer Audit. LAPC is defined as arterial involvement > 90° and/or portomesenteric venous > 270° involvement or occlusion. RESULTS Overall, 142 patients underwent resection for LAPC, of whom 34.5% met the 2022 National Comprehensive Cancer Network criteria. FOLFIRINOX was the most commonly (93.7%) used chemotherapy [median 5 cycles (IQR 4-8)]. Venous and arterial resections were performed in 51.4% and 14.8% of patients. Most resections (73.9%) were performed in high-volume centers (i.e., ≥ 60 pancreatoduodenectomies/year). Overall median volume of LAPC resections/center was 4 (IQR 1-7). In-hospital/30-day major morbidity was 37.3% and 90-day mortality was 4.2%. Median OS from diagnosis was 26 months (95% CI 23-28) and 5-year OS 18%. Surgery in high-volume centers [HR = 0.542 (95% CI 0.318-0.923)], ypN1-2 [HR = 3.141 (95% CI 1.886-5.234)], and major morbidity [HR = 2.031 (95% CI 1.272-3.244)] were associated with OS. CONCLUSIONS Resection of LAPC following chemo(radio)therapy is infrequently performed in the Netherlands, albeit with acceptable morbidity, mortality, and OS. Given these findings, a structured nationwide approach involving international centers of excellence would be needed to improve selection of patients with LAPC for surgical resection following induction therapy.

J Taibah Univ Med Sci 2024; 19:351-358. [PMID: 38357584 PMCID: PMC10864806 DOI: 10.1016/j.jtumed.2024.01.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Revised: 12/14/2023] [Accepted: 01/22/2024] [Indexed: 02/16/2024] Open
Abstract
Objective We aimed to determine the effects of fetal hemoglobin induction therapy in restricting or even reversing the cephalometric changes associated with beta thalassemia. Materials and methods In this comparative observational study, 90 participants were equally divided into three groups: a control group; patients with thalassemia major receiving blood transfusion (BT group); and patients receiving induction therapy (i.e., hydroxyl urea (5-10 mg/kg/day) or as much as 20 mg/kg/day) and thalidomide (2-10 mg/kg/day) along with blood transfusion (IT group). All patients underwent history taking and examination, photographic assessment, and radiographic evaluation with a lateral cephalogram. One-way ANOVA followed by post-hoc Tukey test was used to determine differences among groups. Results The IT group differed significantly from the BT group in all photographic and skull table parameters, and most cephalometric parameters, such as facial angle (p ≤ 0.001), middle and lower facial heights (p ≤ 0.001), and inter-incisal angle (p = 0.036); the mean values in the IT group were similar to those in the control group. In-addition, dental and soft tissue measurements significantly differed among groups. For most parameters, the mean difference indicated higher values in the BT group. Conclusion Induction therapy appeared to improve the facial angles, heights, and inter-incisal angles, whereas a class II skeletal pattern was observed in the transfusion only group. These findings suggest that fetal hemoglobin induction therapy might have restricted some of the cephalometric changes in patients with beta thalassemia.

Abstract
PURPOSE Individual prediction of treatment response is crucial for personalized treatment in multimodal approaches against head-and-neck squamous cell carcinoma (HNSCC). So far, no reliable predictive parameters for treatment schemes containing immunotherapy have been identified. This study aims to predict treatment response to induction chemo-immunotherapy based on the peripheral blood immune status in patients with locally advanced HNSCC. METHODS The peripheral blood immune phenotype was assessed in whole blood samples in patients treated in the phase II CheckRad-CD8 trial as part of the pre-planned translational research program. Blood samples were analyzed by multicolor flow cytometry before (T1) and after (T2) induction chemo-immunotherapy with cisplatin/docetaxel/durvalumab/tremelimumab. Machine Learning techniques were used to predict pathological complete response (pCR) after induction therapy. RESULTS The tested classifier methods (LDA, SVM, LR, RF, DT, and XGBoost) allowed a distinct prediction of pCR. Highest accuracy was achieved with a low number of features represented as principal components. Immune parameters obtained from the absolute difference (lT2-T1l) allowed the best prediction of pCR. In general, less than 30 parameters and at most 10 principal components were needed for highly accurate predictions. Across several datasets, cells of the innate immune system such as polymorphonuclear cells, monocytes, and plasmacytoid dendritic cells are most prominent. CONCLUSIONS Our analyses imply that alterations of the innate immune cell distribution in the peripheral blood following induction chemo-immuno-therapy is highly predictive for pCR in HNSCC.

Abstract
BACKGROUND Lupus nephritis (LN) is a common serious presentation of systemic lupus erythematosus. Cyclophosphamide (CYC) and mycophenolate mofetil (MMF) are listed as the first-line drugs in induction therapy for LN. OBJECTIVE This study aimed to compare high- and low-dose CYC in a cohort of Egyptian LN patients. PATIENTS AND METHODS The data of 547 patients with class III/IV active LN who received CYC as induction therapy were retrospectively analyzed. Whereas 399 patients received 6‑monthly 0.5-1 g/m2 CYC doses, 148 patients received six biweekly 500 mg CYC doses. Demographic data, laboratory test results, and disease activity index were recorded and compared at presentation and at 6, 12, 18, 24, and 48 months of follow-up. RESULTS After 48 months, the proportion of patients maintaining normal creatinine levels was higher in the group receiving induction therapy with high-dose CYC (67.9%, 60.4%, p = 0.029), and these patients also had higher proteinuria remission at 36 (26.6%, 14.8%, p = 0.014) and 48 months (24.3%, 12.8%, p = 0.006). Comparison of patient outcomes according to both induction and maintenance therapy showed the best results in patients who received high-dose CYC and continued MMF as maintenance therapy. CONCLUSION High- and low-dose CYC are comparable in early phases of treatment. However, after a longer duration of follow-up, high-dose CYC was associated with higher remission rates in the current cohort.

Abstract
OBJECTIVE Although sporadic case reports have demonstrated successful management of eosinophilic granulomatosis with polyangiitis (EGPA) by anti-IL-5 therapy, larger-scale monocentric studies for the efficacy of mepolizumab (MEP), an IL-5 monoclonal antibody, are still lacking in Taiwan. METHODS Hospitalized EGPA patients aged at least 18 years were enrolled from November 1998 to October 2023, and analyzed for demographic, clinical, laboratory, medication and outcome data, focusing on the efficacy and safety of biologics use, particularly induction therapy with MEP. RESULTS Twenty-seven EGPA patients aged 10-70 years (43 ± 15) at disease diagnosis were recruited with 21 under combined corticosteroids/cyclophosphamide induction therapy. Seventeen patients received biologics with 13 under MEP therapy. Ten patients aged 19-71 years (48 ± 15) completed 12-month induction therapy with a 100 mg quadri-weekly subcutaneous injection regimen indicated for active or relapse disease. There were reduced BVAS with complete remission in 6 and partial remission in 4 patients, lower CRP levels, decreased eosinophil counts with an inhibition of 92∼96 %, and tapered prednisolone dosages from 5 to 25 (13.0 ± 6.3) to 0-10 (3.3 ± 3.1) mg/day. Only one patient had an adverse event of injection site reactions. Nine patients received the same regimen for annual maintenance therapy. All had a persistent clinical remission. In these patients, 13-56 injections (41 ± 15) were prescribed with a follow-up period of 12∼52 months (38 ± 14). CONCLUSION In this retrospective study, induction therapy with a 12-month 100 mg MEP quadri-weekly subcutaneous injection regimen demonstrates the efficacy and safety for active and relapsing EGPA patients.

Abstract
BACKGROUND A prospective evaluation of non-alcoholic fatty liver disease (NAFLD) during induction therapy for acute lymphoblastic leukemia (ALL) has not been performed. Herein, we prospectively investigated the frequency, risk factors, and outcomes of NAFLD during induction therapy in children and adolescents with B-cell precursor ALL (BCP-ALL). METHODS This study enrolled 74 newly diagnosed BCP-ALL cases aged 1 year and older who were admitted to our department between January 2011 and December 2020. Median age was 6.6 years (1.3-17.5 years). Plain computed tomography (CT) of the upper abdomen was performed before induction therapy, and on days 15 and 29 after initiation of induction therapy. Patients with a liver/spleen CT ratio <0.9 were defined as having NAFLD. RESULTS The frequency of NAFLD was 73%. Patients with NAFLD had a higher rate of hypertriglyceridemia. There was no significant difference in 5-year overall survival and event-free survival (EFS) between patients with and without NAFLD. However, after restricting the target age to 10 years and older, 5-year EFS was significantly higher in patients with NAFLD than in those without (88.5 vs. 42.9%, respectively, P = 0.037). Similarly, 5-year cumulative incidence of relapse (CIR) was significantly lower in patients with NAFLD than in those without it (5-year CIR, 6.3 vs. 57.1%, respectively, P = 0.013). CONCLUSION Patients with NAFLD exhibit better outcomes including 5-year EFS and CIR. Further studies are necessary.

Abstract
BACKGROUND The optimal sequence and combination of surgery, chemotherapy and radiotherapy in patients with N2 non-small cell lung cancer (NSCLC) remain undefined. The aim of our study was to compare two treatment options for N2 NSCLC-induction therapy with subsequent surgery versus upfront surgery with adjuvant treatment. METHODS We retrospectively reviewed 405 patients with N2 disease in two centers, between January 2010 and December 2016. They were divided into two groups: the Induction Group, composed of patients who received neoadjuvant chemotherapy, and the Upfront surgery Group, composed of patients who underwent surgery as first-line therapy. Propensity score-matched (PSM) analysis was performed, and 52 patients were included in each group. Primary endpoints were: recurrence, overall survival (OS) and disease-free survival (DFS). RESULTS After the PSM, no differences were observed in general characteristics, perioperative results, rates and severity of complications, and histopathology results. Seventeen patients (32.7%) of the induction group and 21 (40.4%) of the upfront surgery group had mediastinal lymph nodal involvement with skipping (p = 0.415). Recurrence rate was not different between the two groups (57.7% vs 50.0%, p = 0.478). No differences were observed in terms of OS (40.98 ± 35.78 vs 37.0 ± 40.69 months, p = 0.246) and DFS (29.67 ± 36.01 vs 27.96 ± 40.08 months, p = 0.697). The multivariable analysis identified the pT stage and skipping lymph node metastasis as independent predictive factors for OS. CONCLUSIONS Upfront surgery followed by adjuvant therapy does not appear inferior in terms of recurrence, OS and DFS, compared to induction chemotherapy with subsequent surgery.

Abstract
The study aimed to determine the influence of induction therapy on the acute cellular rejection (ACR) index in adult heart transplant recipients during the one-year observation. The study population consisted of 256 consecutive adult patients (pts), aged 51.5 (±11.9) years, 199 (77%) men treated with orthotopic heart transplantation (OHT) in the period between 2015 and 2020 in a single high-volume heart transplant center. The endomyocardial biopsies (EMBs) were performed according to the protocol consisting of 7 protocolary EMBs for up to 3 months and 10 EMBs for up to one year after OHT. The rejection index (ACRI) was calculated as the number of scheduled EMBs with the ACR ≥ 2 divided by the total number of protocolary EMBs. The study population was divided into two groups according to the application of basiliximab. The total number of pts. who received basiliximab was 10 (3.9%). The main indications for the usage of the induction therapy were heart retransplantation, mechanical circulatory support (MCS), severe renal insufficiency (eGFR <30 mL/min/1.73 m2), and a panel of reactive antibody (PRA) > 10%. In the group with induction, the mean age was 49 (±14) years; 3 (30%) patients had the MCS prior to OHT, and 3 (30%) patients had heart retransplantation. Four (40%) patients had diabetes mellitus, and 4 (40%) patients had severe renal insufficiency. As maintenance therapy during the observation period, tacrolimus was given to 10 (100%) patients, everolimus to 2 (20%) patients, and MPA to 9 (90%) patients. In the group with no induction, the mean age was 51.8 (±12) years, MCS was used in 56 (23%) patients, 2 (0.8%) patients were retransplanted; 10 (4%) patients had eGFR <30 mL/min/1.73 m2 and 58 (24%) patients had diabetes. Tacrolimus was administered to 243 (99%) patients, cyclosporine to 3 (1%), everolimus to 40 (16%), and mycophenolate to 245 (99.6%) heart recipients. The median one-year ACRI was 0.0, IQR:0.0-0.08 in the group with induction vs. 0.077, IQR: 0.0-0.154 with no induction; p = 0.11. ACRI up to three months was significantly higher in the entire cohort in comparison to up to one year (P < 0.01). The multivariate analysis showed that only everolimus implementation and younger age at the time of transplant influenced patients' mortality rate (P < 0.01). Significant graft rejections (≥ 2R ISHLT) are most common in the first three months after OHT. Patients who are initially at high risk of significant cellular rejection may benefit from induction therapy.

Abstract
INTRODUCTION The aim of this study is to assess the outcomes of different induction therapies among mild to moderate immunological risk kidney transplants in the era tacrolimus and mycophenolate-derivate based maintenance. METHODS This was a retrospective cohort study using data from the United States Organ Procurement and Transplantation Network among mild to moderate immunological risk living-donor KTRs, defined as having first transplant and panel reactive antibodies less than 20% but with two HLA-DR mismatches. KTRs were divided into two groups based on induction therapy with either thymoglobulin or basiliximab. Instrumental variable regression models were used to assess the effect of induction therapy on acute rejection episodes, serum creatinine levels and graft survival. RESULTS Of the entire cohort, 788 patients received basiliximab while 1727 patients received thymoglobulin induction. There were no significant differences between basiliximab versus thymoglobulin induction in acute rejection episodes at one-year post-transplant (coefficient= -0.229, p value = .106), serum creatinine levels at one-year post-transplant (coefficient= -0.024, p value = .128) or death-censored graft survival (coefficient: - <0.001, p value = .201). CONCLUSION This study showed no significant difference in acute rejection episodes or graft survival when using thymoglobulin or basiliximab in mild to moderate immunological risk living donor KTRs, maintained on tacrolimus and mycophenolate-based immunosuppressive regimen.

Abstract
Recurrent IgA nephropathy (rIgAN) is an important cause of kidney allograft loss. Till now, no proven strategies have been confirmed to prevent/decrease the rIgAN. Here, a systematic review and meta-analysis were performed on the available interventions impacting rIgAN. PubMed, Embase, Web of sciences, ProQuest, and Cochrane library databases along with Google Scholar were searched for articles evaluating the rIgAN after kidney transplantation (up to 23 February 2023). The main inclusion criteria were kidney transplantation because of primary IgAN and articles studying the rate of the rIgAN based on different therapeutic interventions to find their effects on the disease recurrence. Based on our criteria, 11 papers were included in this systematic review, two of which pleased the criteria for the meta-analysis. Meta-analysis showed that the risk of the rIgAN in the steroid-free group was 3.33 times more than that of the steroid-receiving group (Pooled Hazard Ratio = 3.33, 95% CI 0.60 to18.33, Z-value = 1.38, p-value = 0.16). Steroid-free therapy increases the risk of rIgAN in kidney transplant recipients with primary IgAN. High-quality trials with large sample sizes studies are needed to confirm the impact of the steroids on decreasing the rate of the rIgAN.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is a type of blood cancer that affects the bone marrow and blood cells. AML is characterized by the rapid growth and accumulation of abnormal white blood cells, known as myeloblasts, which interfere with the production of normal blood cells. AIMS The main aim was to determine the relationship between these genetic alterations and the clinico-haematological parameters and prognostic factors with therapy for Iraqi patients with AML. METHODS We used Sanger Sequencing to detect the mutations in 76 AML patients. Clinical data of AML patients were retrospectively analysed to compare the prognosis of each gene mutation group. RESULTS Somatic mutations were identified in 47.4% of the enrolled patients in a core set of pathogenic genes, including FLT3 (18 patients, 23.7%), DNMT3A (14, 18.4%), NPM1 (11, 14.5%) and TP53 (5, 6.8%). As multiple mutations frequently coexisted in the same patient, we classified patients into 10 further groups. Two novel mutations were detected in FLT3-ITD, with new accession numbers deposited into NCBI GenBank (OP807465 and OP807466). These two novel mutations were computationally analysed and predicted as disease-causing mutations. We found significant differences between patients with and without the detected mutations in disease progression after induction therapy (remission, failure and death; pv = < 0.001) and statistically significant differences were reported in total leukocyte count (pv = < 0.0001). CONCLUSION These genes are among the most frequently mutated genes in AML patients. Understanding the molecular and clinical significance of these mutations is important for guiding treatment decisions and predicting patient outcomes.

Abstract
BACKGROUND The choice of induction therapy in kidney transplantation is often non-standardized and centre-specific. Clinicians can choose between depleting and non-depleting antibodies, which differ in their immunosuppressive capacity and the concomitant risk of infection. We herein present a standardized risk-stratified algorithm for induction therapy that might help to balance the risk of rejection and/or serious infection. METHODS Prior to kidney transplantation, patients were stratified into low-risk, intermediate-risk or high-risk according to our protocol based on immunologic risk factors. Depending on their individual immunologic risk, patients received basiliximab (low risk), antithymocyte globulin (intermediate risk) or low-dose alemtuzumab (high risk) for induction therapy. We analysed the results after 3 years of implementation of our risk-stratified induction therapy protocol at our kidney transplant centre. RESULTS Between 01/2017 and 05/2020, 126 patients were stratified in accordance with our protocol (low risk/intermediate risk/high risk: 69 vs. 42 vs. 15 patients). The median follow-up time was 1.9 [1.0-2.5] years. No significant difference was observed in rejection rate and allograft survival (low risk/intermediate risk/high risk: 90.07% vs. 80.81% vs. 100% after 3 years (p > 0.05)) among the groups. The median eGFR at follow-up was (low risk/intermediate risk/high risk) 47 [33-58] vs 58 [46-76] vs 44 [22-55] ml/min/1.73 m2. Although the rate of viral and bacterial infections did not differ significantly, we observed a higher rate of opportunistic fungal infections with alemtuzumab induction. CONCLUSIONS Our strategy offers facilitated and individualized choice of induction therapy in kidney transplantation. We propose further evaluation of our algorithm in prospective trials.

Abstract
BACKGROUND The occurrence of autoantibodies in human immunodeficiency virus (HIV)-infected patients has been previously reported, with a prevalence ranging from 20 to 83%. There are also a few reports of clinically relevant autoantibody profiles in HIV-positive patients that lead to true systemic autoimmune disease; these possible life-threatening diseases have to be considered and treated accordingly. CASE PRESENTATION Here, we present the case of a 29-year-old female patient with a history of well-controlled HIV infection in the last 6 years who was admitted to our department for the evaluation of acute kidney injury and nephrotic syndrome with active urinary sediment. A diagnosis of systemic antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) with renal and pulmonary involvement was established. The patient was treated with cyclophosphamide, rituximab and tapering glucocorticoids,and the diffuse alveolar hemorrhage resolved, but the evolution of kidney function was unfavorable, which led to the need to initiate hemodialysis. We highlight the importance of establishing the correct diagnosis, treating the disease accordingly and the possible clinical issues that can appear in a patient with HIV infection during immunosuppressant treatment as induction treatment. Additionally, we performed a thorough literature review of ANCA positivity in HIV-infected patients to properly understand the current evidence. CONCLUSIONS Although it is not clear whether HIV infection and AAV are causally or coincidentally related, the possibility of this systemic autoimmune phenomenon should be acknowledged by physicians to establish the correct diagnosis and treat the disease accordingly by maintaining a balance between the risks and benefits of immunosuppression in this category of patients, with treatment decisions being made by the members of a multidisciplinary team in centers with experience in AAV.

Abstract
Intensive chemotherapy is the backbone of induction treatment in patients with acute myeloid leukemia (AML). However, AML patients with concomitant cardiac disease may not be eligible for anthracycline-based therapies. In a small cohort of patients, we have previously shown that anthracycline-free, amsacrine-based chemotherapy TAA (thioguanine, cytarabine, amsacrine) may be as effective as cytarabine/daunorubicin for induction therapy in these patients. In this systematic retrospective single-center analysis, we documented the outcome of 31 patients with significant cardiac comorbidities including coronary heart disease or cardiomyopathy receiving TAA as induction chemotherapy. Median (range) ejection fraction (EF) was 48% (30-67%) in this cohort. Patients with EF below 30% were considered unfit for intensive induction therapy. Event-free survival (EFS), overall survival (OS), and relapse-free survival (RFS) were 1.61, 5.46, and 13.6 months respectively. Poor outcome was primarily related to a high early mortality rate within the first 30 days of therapy, mainly caused by infectious complications. TAA cannot be recommended as a substitute of standard induction for AML patients with significant concomitant cardiac disease. In the era of novel agents, alternative strategies (e.g., hypomethylating agents plus venetoclax) should be considered when anthracycline-based regimens are not suitable.

Abstract
PURPOSE Induction immunosuppression has improved the long-term outcomes after kidney transplant. This study explores the association of different induction immunosuppression medications (Basiliximab vs. Alemtuzumab vs. rabbit Antithymocyte Globulin) used at the time of kidney transplant with the development of de novo donor-specific HLA antibodies (DSA) in the first 12 months post-transplant period. METHODS A total of 390 consecutive kidney transplant recipients (KTR), between 2016 and 2018, were included in the analysis. A 104 (26.6%) received Basiliximab, 186 (47.6%) received Alemtuzumab, and 100 (25.6%) received rabbit Antithymocyte Globulin (rATG) for induction. All recipients had a negative flow cytometry crossmatch before transplant. Serum samples at 4- and 12-months post-transplant were assessed for the presence of de novo HLA DSA. kidney allograft function was compared among the three groups with calculated Creatinine Clearance on 24 h urine collection. RESULTS De novo HLA DSA were detected in total of 81 (20.8%) patients within 12 months post-transplant. De novo HLA DSA were detected in 12/104 (11.5%), 43/186 (23.11%), and 26/100 (26%) KTR that received Basiliximab, Alemtuzumab, and rATG respectively (p = 0.006). KTR that received Basiliximab were significantly older, and the last follow-up creatinine clearance was significantly lower at 42 ml/min compared to KTR that received Alemtuzumab or rATG (p = 0.006). CONCLUSION Induction immunosuppression utilizing Basiliximab is associated with significant reduction in development of de novo DSA within the first 12-months post kidney transplant but had lower creatinine clearance with long-term follow up.

Abstract
Childhood-onset systemic lupus erythematosus (SLE) is characterized by increased rates of kidney involvement, termed lupus nephritis. Despite the significant morbidity and mortality associated with this disease, lupus nephritis trials have been plagued by repeated failures to meet clinical endpoints. However, improvements in trial design and the development of targeted approaches have begun to yield promising results, including two new FDA-approved lupus nephritis treatments since 2020. These include belimumab, a monoclonal antibody targeting the B cell survival cytokine BAFF (B cell activating factor), and voclosporin, a cyclosporin analog with improved pharmacokinetic characteristics. In this review, we will summarize the data supporting regulatory approval for these agents in lupus nephritis and highlight ongoing clinical trials targeting the diverse immunologic drivers of renal inflammation in SLE. While pediatric patients remain underrepresented in lupus clinical trials, given the increased severity of childhood-onset SLE and need for long-term protection from kidney damage, we anticipate the need for off-label use of these targeted therapies in the pediatric population. Future studies are needed to define optimal patient selection, drug combinations, and treatment duration in pediatric lupus nephritis.

Abstract
The optimal approach to locally advanced head and neck squamous cell carcinoma (LAHNSCC) treatment remains controversial. For non-resectable LAHNSCC, the clinical interest of induction chemotherapy followed by concurrent chemoradiotherapy (CCRT) or radiotherapy has been questioned. With the approval of immunotherapy and targeted therapy for this disease, treatment options have become more complex. Although new trial data have appeared every year, the results are still inconclusive. In this review, we provide readers with information on new strategies for LAHNSCC induction therapy, which will facilitate evidence-based decision making in LAHNSCC treatment.

Abstract
A randomized inter-group trial comparing more intensive treatment strategies to a common standard arm 3 + 7 (CSA) was conducted in patients with non-M3 AML. Untreated patients ≥ 60 years were allocated to the CSA (n = 132) or to the study group arms (n = 1154) of the AMLCG (TAD/HAM versus HAM/HAM ± G-CSF followed by TAD and maintenance) and the OSHO (intermediate-dose ara-C/mitoxantrone followed by ara-C/mitoxantrone). Median age of the 1147 eligible patients was 69 (range 60-87) years. CR/CRi status at 90 days was not significantly different between the CSA (54% (95%CI: 45-64)) and the study group arms (53% (95%CI: 47-60) and 59% (95%CI: 58-63)). The five-year event-free survival (EFS) probability (primary endpoint) was 6.2% (95%CI: 2.7-14.0) in the CSA, 7.6% (95%CI: 4.5-12.8) in study group A and 11.1% (95%CI: 9.0-13.7) in B. The 5-year OS was 17.2% (95%CI: 11.0-26.9), 17.0% (95%CI: 2.0-23.9), and 19.5% (95%CI: 16.7-22.8) in CSA, study group A and B, respectively. Neither study group differed significantly from the CSA regarding EFS, OS, or relapse-free survival. In multivariate analyses, allocation to the treatment strategy was not significantly associated with the time-to-event endpoints. The evaluation of more intensive treatment strategies did not show clinically relevant outcome differences when compared to CSA.

Abstract
Since its first description 40 years ago, huge strides have been made in the management of ANCA-associated vasculitis with improved patient outcomes. The use of cyclophosphamide and/or B-cell depleting therapy alongside glucocorticoids remains the cornerstone of therapy in organ or life-threatening disease, but recent trials have re-evaluated existing treatment strategies, alongside the development of new treatment targets. This has led to refinement of the role of plasma exchange, the use of reduced dosing of oral glucocorticoids with improved patient outcomes, as well as other treatment adjuvants/options of steroid minimization including C5a receptor antagonism and IL-5 inhibition. In this review we examine developments in remission induction therapy for ANCA-associated vasculitis.

Abstract
BACKGROUND Tofacitinib is an oral small molecule Janus kinase inhibitor for the treatment of ulcerative colitis. AIM To report efficacy and infection rates in patients receiving tofacitinib induction treatment, by baseline corticosteroid status. METHODS We evaluated efficacy and safety data from OCTAVE Induction 1&2 in patients with moderately-to-severely active ulcerative colitis who received tofacitinib 10 mg twice daily or placebo for 8 weeks, based on induction baseline oral corticosteroid use (Corticosteroid-Yes/No) and dose (< 20/ ≥ 20 mg/day). Infections of interest included serious infections, herpes zoster (HZ), and adjudicated opportunistic infections (OIs). RESULTS At OCTAVE Induction 1&2 baseline, 478/1092 (43.8%) patients were receiving corticosteroids. Tofacitinib demonstrated significant induction efficacy versus placebo for both Corticosteroid-Yes and Corticosteroid-No. With adjustment for prior tumor necrosis factor inhibitor and immunosuppressant failure, there were no statistically significant differences in remission and clinical response rates for Corticosteroid-Yes versus Corticosteroid-No. Among tofacitinib-treated patients, HZ and OIs occurred more frequently in Corticosteroid-Yes versus Corticosteroid-No, regardless of dose (< 20 mg vs. ≥ 20 mg). Infection incidence rates (regardless of severity/seriousness) during tofacitinib induction were generally similar regardless of baseline corticosteroid use. The proportion of tofacitinib-treated patients with HZ was 0.2% for Corticosteroid-No versus 1.1% for Corticosteroid-Yes < 20 mg and 1.0% for Corticosteroid-Yes ≥ 20 mg. Two out of three patients had HZ OIs. CONCLUSIONS Tofacitinib induction efficacy (clinical response and remission) was similar in baseline corticosteroid subgroups. Infections of interest were rare; HZ and OIs occurred more frequently among those receiving tofacitinib and corticosteroids versus those receiving tofacitinib without corticosteroids.

Abstract
BACKGROUND Induction agents have proved to reduce the rate of acute rejection (AR) in kidney transplant recipients (KTRs) without improving long-term graft and patient survival (PS). OBJECTIVE This study evaluates the utility of induction therapy in low immunological risk KTRs regardless of donor-to-recipient HLA matching. METHODS We retrospectively reviewed the records of 218 patients undergoing kidney transplantation (KT). These patients were divided into two groups according to the usage of induction therapy: 82 did not receive any induction therapy (Group I), and 136 patients received either Anti-IL2 receptor antibodies or anti-thymocyte globulin (Group II). All patients had panel reactive antibody (PRA) < 20% and absence of donor-specific antibodies (DSA). The difference in outcomes were assessed at different intervals following KT. RESULTS The rate of bacterial infections at one year (p-value = 0.032) and the frequency of CMV disease (p-value = 0.044) were significantly higher in Group II (with induction therapy). The duration of hospital stay, the rate and severity of acute rejection, the occurrence of delayed graft function, the rate and type of surgical complications at one year, and the graft function and survival at one and three years were similar between the two groups (p-value = NS). In addition, the financial burden is much less in Group I (without induction therapy), reducing the total cost of the transplant procedure. CONCLUSION We conclude that induction therapy in low-immunological risk kidney transplant patients is not a must regardless of donor-to-recipient HLA matching. Therefore, induction therapy did not yield significant health results, but had negative financial consequences.

Abstract
INTRODUCTION There are various doses, durations, and strains of bacillus Calmette-Guérin (BCG) intravesical instillation therapy, but optimal treatment has not yet been established. We retrospectively investigated the efficacy and safety of low-dose BCG therapy for non-muscle-invasive bladder cancer (NMIBC) and carcinoma in situ (CIS) in a multicenter study. METHODS From 1991 to 2019, 323 patients who received BCG therapy to prevent recurrence of NMIBC were analyzed as group A. Similarly, 147 patients who received BCG therapy for the treatment of CIS were analyzed as group B. Patients received low- or full-dose Tokyo-172 strain or full-dose Connaught strain, and the three strains were compared. Survival curves were estimated by the Kaplan-Meier method, and independent risk factors for intravesical recurrence were examined by multivariate logistic regression. RESULTS Recurrence-free survival (RFS) in group A was significantly better for the Connaught strain than the low-dose Tokyo-172 strain (p = 0.026), but not between the low- and full-dose Tokyo-172 strains (p = 0.443). RFS of group B, cancer-specific survival, and progression-free survival in both groups did not show statistically significant differences. Logistic analysis of group A showed that for intravesical recurrence, only pT1 was a significant risk factor, and there were no differences between the BCG strain and dose and no significant factors in group B. There were also no differences in the completion rate in both groups, but adverse events such as urinary frequency and feeling of residual urine were significantly lower with the low-dose Tokyo-172 strain. CONCLUSION There was no difference in efficacy between the low- and full-dose Tokyo-172 strains, but to minimize adverse events, the low-dose Tokyo-172 strain may be worth considering.

Abstract
BACKGROUND Currently, the standard therapy for autoimmune hepatitis (AIH) consists of a combination of prednisolone and azathioprine. However, 15% of patients are intolerant to azathioprine which necessitates cessation of azathioprine or changes in therapy. In addition, not all patients achieve complete biochemical response (CR). Uncontrolled data indicate that mycophenolate mofetil (MMF) can induce CR in a majority of patients. Better understanding of first-line treatment and robust evidence from randomised clinical trials are needed. The aim of this study was to explore the potential benefits of MMF as compared to azathioprine, both combined with prednisolone, as induction therapy in a randomised controlled trial in patients with treatment-naive AIH. METHODS CAMARO is a randomised (1:1), open-label, parallel-group, multicentre superiority trial. All patients with AIH are screened for eligibility. Seventy adult patients with AIH from fourteen centres in the Netherlands and Belgium will be randomised to receive MMF or azathioprine. Both treatment arms will start with prednisolone as induction therapy. The primary outcome is biochemical remission, defined as serum levels of alanine aminotransferase and immunoglobulin G below the upper limit of normal. Secondary outcomes include safety and tolerability of MMF and azathioprine, time to remission, changes in Model For End-Stage Liver Disease (MELD)-score, adverse events, and aspects of quality of life. The study period will last for 24 weeks. DISCUSSION The CAMARO trial investigates whether treatment with MMF and prednisolone increases the proportion of patients in remission compared with azathioprine and prednisolone as the current standard treatment strategy. In addition, we reflect on the challenges of conducting a randomized trial in rare diseases. TRIAL REGISTRATION EudraCT 2016-001038-91 . Prospectively registered on 18 April 2016.
