Abstract

Renal impairment (RI) is frequently caused by multiple myeloma (MM), which makes clinical care more difficult if renal function deteriorates or renal failure develops. Thus, in this investigation, we looked at the relationship between HOXA5&NDRG2 promoter methylation in MM patients and evaluated their prognostic potential in predicting RI risk in MM patients.&#xa0;This study included 60 control volunteers and 120 MM patients. The promoter methylations of HOXA5&NDRG2 were quantitatively evaluated by real-time PCR (qPCR) after the extraction of gDNA from whole blood and then treated with bisulfite.&#xa0;The promoter methylation percentages of HOXA5&NDRG2 were significantly increased in MM patients (77.16&#x2009;&#xb1;&#x2009;2.43&45.49&#x2009;&#xb1;&#x2009;2.16;p&#x2009;<&#x2009;0.05) when compared to controls (4.47&#x2009;&#xb1;&#x2009;0.61&3.33&#x2009;&#xb1;&#x2009;0.31,respectively), in stage II&III patients when compared to stage I patients and in patients with age&#x2009;&#x2265;&#x2009;60 years when compared to patients with age&#x2009;<&#x2009;60 years. While only the methylation percentage of NDRG2 promoter was significantly increased in MM patients with RI (53.61&#x2009;&#xb1;&#x2009;3.21,p&#x2009;<&#x2009;0.05) when compared to MM patients without RI (37.37&#x2009;&#xb1;&#x2009;2.04). Results obtained from ROC curve revealed that both HOXA5&NDRG2 promoter methylation were good diagnostic tools for MM. The NDRG2 promoter methylation was good prognostic biomarker could predict renal while HOXA5 promoter in the prediction of MM staging. The Kaplan-Meier survival test showed that patients with higher HOXA5&NDRG2 promoter methylation had a shorter OS and a worse prognosis. Only NDRG2 promoter hypermethylation was significantly associated with the risk of RI development in MM patients.&#xa0;HOXA5&NDRG2 promoter hypermethylation may have roles in the molecular etiology of MM and could be used as a treatment regimen.

PPRC1 is a prognostic biomarker and key regulator of mitochondrial oxidative phosphorylation in multiple myeloma.

BACKGROUND: Multiple myeloma (MM) remains an incurable haematological malignancy, underscoring the need for novel prognostic biomarkers and therapeutic targets. This study aimed to investigate the clinical and biological significance of peroxisome proliferator-activated receptor gamma coactivator-related protein 1 (PPRC1) in MM. METHODS: Expression and clinical data were obtained from public databases and an independent local cohort. Kaplan-Meier and Cox regression analyses were performed to evaluate prognostic value. Differential expression analysis, pathway enrichment analysis and single-cell RNA-seq data analysis were used to explore biological functions. PPRC1 was silenced in MM cell lines using siRNA to assess its effects on cell survival and oxidative phosphorylation. RESULTS: PPRC1 was significantly upregulated in MM and was associated with advanced disease stage and poor overall survival. Multivariate Cox analysis identified PPRC1 as an independent prognostic factor. A nomogram incorporating PPRC1 and revised-ISS improved survival prediction. Functional analyses revealed that PPRC1 was positively correlated with oxidative phosphorylation and oncogenic signalling pathways. A potential connection between PPRC1 expression and immune cell infiltration was observed. PPRC1 knockdown inhibited cell proliferation, induced cell cycle arrest and apoptosis and impaired oxidative phosphorylation in MM. CONCLUSIONS: PPRC1 acts as a prognostic biomarker and metabolic regulator in MM by sustaining mitochondrial oxidative phosphorylation. These findings highlight PPRC1 as a potential therapeutic target in MM.

Photon-counting detector computed tomography (PCD-CT) in multiple myeloma: a systematic review and trial sequential meta-analysis on image quality and radiation dose.

OBJECTIVES: To systematically review and perform a meta-analysis comparing the effects of PCD-CT versus EID-CT on image quality (sharpness) and radiation dose (CTDIvol) in patients with bone lesions due to multiple myeloma&#xa0;(MM). METHODS: A comprehensive search of PubMed, Embase, Scopus, and Cochrane Central was conducted from inception to October 2025. Studies comparing PCD-CT and EID-CT in MM patients were included. Methodological quality was assessed using ROBINS-I, and the certainty of evidence was assessed using GRADE. RESULTS: A total of 41 studies were identified that matched our search criteria. After duplicate removal and screening, five studies (n = 170 patients) were included in the systematic review, with four contributing to the meta-analysis. PCD-CT showed a significant pooled mean difference in image sharpness (mean difference, + 0.99 points; 95% CI, 0.62-1.37; p < 0.001). PCD-CT also demonstrated a reduction in radiation dose (mean difference, -4.95 milligrays; 95% CI, -8.39 to -1.50; p = 0.005). Trial sequential analysis (TSA) confirmed stability of pooled estimates, with conclusive evidence for image sharpness improvement, and suggestive yet incomplete evidence for radiation dose reduction. CONCLUSION: Compared to EID-CT in MM, PCD-CT significantly improves subjective image sharpness as supported by trial sequential analysis. Conventional meta-analysis suggested a reduction in radiation dose with PCD-CT; however, trial sequential analysis indicated that the cumulative evidence remains inconclusive. Further large-scale studies are suggested to confirm the magnitude of the radiation dose reduction benefit.

Risk of adverse events in elotuzumab-treated patients with multiple myeloma: a systematic review and meta-analysis.

BACKGROUND: Elotuzumab, an anti-SLAMF7 monoclonal antibody for multiple myeloma (MM), lacks&#xa0;a comprehensive safety profile from meta-analysis. METHODS: We&#xa0;systematically searched PubMed, Web of Science, EMBASE and CENTRAL through February 13, 2025 for randomized controlled trials (RCTs) evaluating elotuzumab in MM. Pooled relative risks(RRs) of adverse events observed in elotuzumab-containing regimens versus control therapies. RESULTS: 6 RCTs (N=1,736) were included. Elotuzumabsignificantly reduced incidence of neutropenia (RR = 0.86, 95% CI: 0.76-0.98), but increased risks of cough (RR = 1.41, 95% CI: 0.96-2.09), pneumonia (RR = 1.30, 95% CI: 1.07-1.59), diarrhea (RR = 1.16, 95% CI: 1.05-1.30), pyrexia (RR = 1.47, 95% CI: 1.10-1.96) and infections (RR = 1.09, 95% CI: 1.03-1.15). No significant differences were observed for anemia, thrombocytopenia, respiratory infections, nausea, appetite loss, back pain, muscle spasms, peripheral edema, insomnia, rash, pruritus, fatigue, or hypokalemia. For grade 3-4 events, elotuzumab was&#xa0;associated with higher risks of lymphopenia (RR = 1.86, 95% CI: 1.31-2.64, p&#x2009;=&#x2009;0.0005, I2 = 9%), diarrhea (RR = 1.47, 95% CI: 1.00-2.17), pneumonia (RR = 1.57, 95% CI: 1.11-2.23), cataracts (RR = 2.87, 95% CI: 1.15-7.21) and infections (RR = 1.30, 95% CI: 1.04-1.62). CONCLUSION: Elotuzumab in MM&#xa0;appears&#xa0;safe but with a specific&#xa0;adverse events pattern :&#xa0;lower neutropenia,&#xa0;but higher respiratory, gastrointestinal, metabolic, and infectious events. Differences may be influenced by longer treatment and corticosteroid use; therefore, interpretation of outcomes such as hyperglycemia and cataracts requires particular caution.
