Objective: We performed a scoping review of randomised clinical trials (RCTs) assessing pharmacological therapies for the initial management of lupus nephritis (LN), focusing on study design, included populations and outcome definitions, to assess the generalisability of their results and identify gaps in the evidence. Methods: RCTs evaluating pharmacological interventions for the initial therapy of LN published between 2000 and 2024 were evaluated. Extracted variables included study design, selection criteria, outcome definitions, populations recruited and clinical characteristics of participants. Each study arm was included as intervention and segregated into guideline-recommended regimens (cyclophosphamide (CYC), mycophenolic acid analogues (MPAAs), calcineurin inhibitors and belimumab) or other regimens. Data were analysed by descriptive statistics, and Fragility Index (FI) was estimated to assess robustness of studies. Results: We included 124 intervention arms within 61 RCT, involving 7058 participants. Seventy-nine arms (63.7%) corresponded to guideline-recommended therapies: 33 (26.6%) MPAA, 28 (22.6%) NIH-CYC and 7 (5.6%) triple-drug therapies. While 100% of triple-drug therapies RCT were multinational, only 7.1% of NIH-CYC and 0% of tacrolimus RCTs were conducted in more than one country. Only 9 (14.8%) had follow-up ≥24 months. Ten (16.4%) RCTs exclusively included participants with severe or refractory LN. Only 29 (47.5%) reported serious adverse events, and few described patient-reported outcomes. Black and other race participants were under-represented, as well as participants from Middle East, North Africa, and the sub-Saharan African region. Response was variably defined and assessed at different intervals. Robustness of RCTs evaluating double-drug guideline-recommended therapies were mostly low, with FI ranging from 1 to 3. Conclusions: Considering new recommendations for the management of LN, we call for broader inclusion of under-represented populations and homogenisation of study design. This study provides the rationale for evaluating unexplored treatment comparisons and conducting research on newer interventions in clinical settings where evidence is currently lacking.

Background Hypercalcemia is highly prevalent in kidney transplant recipients with hyperparathyroidism. However, its long-term impact on graft function is uncertain. Methods We conducted a prospective cohort study investigating adverse graft outcomes associated with persistent hypercalcemia (free calcium > 5.2 mg/dL in ≥ 80% of measures) and inappropriately elevated intact parathyroid hormone (> 30 pg/mL) in kidney transplant recipients. Asymptomatic mild hypercalcemia was monitored unless complications developed. Results We included 385 kidney transplant recipients. During a 4-year (range 1–9) median follow-up time, 62% of kidney transplant recipients presented persistent hypercalcemia. Compared to kidney transplant recipients without hypercalcemia, there were no significant differences in graft dysfunction (10% vs. 12%, p = 0.61), symptomatic urolithiasis (5% vs. 3%, p = 0.43), biopsy-proven calcium deposits (6% vs. 5%, p = 1.0), fractures (6% vs. 4%, p = 0.64), and a composite outcome of urolithiasis, calcium deposits, fractures, and parathyroidectomy indication (16% vs. 13%, p = 0.55). In a subset of 76 kidney transplant recipients, subjects with persistent hypercalcemia had higher urinary calcium (median 84 [43–170] vs. 38 [24–64] mg/day, p = 0.03) and intact fibroblast growth factor 23 (median 36 [24–54] vs. 27 [19–40] pg/mL, p = 0.04), and lower 25-hydroxyvitamin D levels (11.3 ± 1.2 vs. 16.3 ± 1.4 ng/mL, p < 0.001). In multivariate analysis, pretransplant intact parathyroid hormone < 300 pg/mL was associated with a reduced risk of post-transplant hypercalcemia (OR 0.51, 95% CI 0.32–0.80). Conclusions Long-term persistent mild hypercalcemia (tertiary hyperparathyroidism) was frequent in kidney transplant recipients in our series. This condition presented with lower phosphate and 25-hydroxyvitamin D, and higher urinary calcium and intact fibroblast growth factor 23 levels compared to kidney transplant recipients without hypercalcemia, resembling a mild form of primary hyperparathyroidism. Despite these metabolic derangements, the risk of adverse graft outcomes was low. Graphical abstract

Cancer is a disease of older adults, with 60% of cancer diagnoses and 70% of cancer deaths occurring in individuals ≥ 65 years. Normal oral aging may transition to disease in the presence of one or more potential modifiers, such as a new oncological diagnosis or a new treatment. Oral conditions in patients with cancer cause significant morbidity. Previous work suggests that oral conditions are neither elicited/assessed/reassessed nor well-managed or investigated in older patients. However, frequently reported oral conditions in patients undergoing cancer therapy include xerostomia, dysgeusia, candidiasis, mucositis, and dental caries. Some oncological treatments such as hematopoietic stem cell transplant or chemotherapy/radiotherapy for head and neck cancers entail higher risks of oral complications. No specific recommendations in the case of older adults with cancer-associated oral conditions are available. Treatment recommendations are based on low levels of evidence and/or evidence extrapolated from younger patients with câncer.
