Rheumatology (Oxford, England) Nov 2023To evaluate the effectiveness and safety of current treatment strategies for the vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome.
OBJECTIVES
To evaluate the effectiveness and safety of current treatment strategies for the vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) syndrome.
METHODS
A protocolized systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was performed. Three databases were searched for reports on treatment strategies for VEXAS. Data from the included publications was extracted and a narrative synthesis was performed. Treatment response was recorded as complete (CR), partial (PR) or none (NR) depending on changes in clinical symptoms and laboratory parameters. Patient characteristics, safety data and previous treatments were analysed.
RESULTS
We identified 36 publications with a total of 116 patients; 113 (98.3%) were male. The identified reports included azacytidine (CR 9/36, 25%; PR 14/36, 38.9%), Janus kinase inhibitors (JAKi) (CR 11/33, 33%; PR 9/33, 27.3%), tocilizumab (CR 3/15, 20%; PR 6/15, 40%), allogeneic stem cell transplantation (CR 6/7, 85.7%; one patient died), anakinra (CR 4/5, 80%; NR 1/5, 20%), canakinumab (CR 1/2, 50%; PR 1/2, 50%) and glucocorticoid monotherapy (CR 1/6, 16.7%; PR 4/6, 66.7%). Individual reports were available for TNF inhibitors, rituximab and MTX. Data on adverse events were available for 67 patients (67/116, 57.8%) and included: pneumonia (12/67, 17.9%), other infections (9/67, 13.4%), venous thromboembolisms (6/67, 8.9%), cytopenias (4/67, 5.9%), and acute (4/67, 5.9%) and chronic graft-vs-host-disease (2/67, 2.9%).
CONCLUSION
Current data on VEXAS treatment are limited and inhomogeneous. Treatment decisions should be individualized. For the devolvement of treatment algorithms clinical trials are needed. Adverse events remain a challenge, especially an elevated risk for venous thromboembolism associated to JAKi treatment should be carefully considered.

Meta-Analysis
The efficacy and safety of venetoclax and azacytidine combination treatment in patients with acute myeloid leukemia and myelodysplastic syndrome: systematic review and meta-analysis.
OBJECTIVES
The meta-analysis sought to evaluate the efficacy and safety of a combination of venetoclax (Ven) and azacitidine (AZA) in the treatment of acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS).
METHODS
We searched PubMed, Excerpta Medica Database (EMBASE), Cochrane Library, and Web of Science for eligible studies from inception to June 2022. We used the Cochrane Risk of Bias 2.0 (RoB 2.0) and Methodological Index for Non-Randomized Studies (MINORS) to evaluate the quality of the included literature. The inverse variance method was used to calculate the pooled proportion and 95% confidence interval (CI).
RESULTS
The meta-analysis included nineteen studies with a total of 1615 patients. The pooled overall CR/CRi (complete response (CR)/complete response with incomplete blood count recovery (CRi)) rate for AML and MDS was 57.9% (95% CI 49.5-65.9%, I = 83%). Subgroup analyses showed that the rate of pooled CR/CRi was 67.5% (95% CI 61.1-73.3%, I = 54%) for the new-diagnosed (ND) AML group, 30% (95% CI 20-44.1%, I = 66%) for relapsed/refractory (R/R) AML, and 67.6% (95% CI 52.6-79.8%, I = 65%) for MDS, respectively. One randomized controlled trial (RCT) showed that CR/CRi was 64.7% in ND-AML patients. A total of 9 studies reported adverse events, with neutropenia being the most common of grade 3-4 adverse events, with a rate of 53.7% (95% CI 61.1-73.3%, I = 54%).
CONCLUSION
The present meta-analysis demonstrated that the Ven + AZA regimen is efficacious for the treatment of AML and MDS, with it being more effective for ND-AML than R/R AML. The most common adverse effects of this regimen are grade 3-4 neutropenia and neutropenia with fever.

Meta-Analysis
Efficacy and safety of venetoclax combined with hypomethylating agents for relapse of acute myeloid leukemia and myelodysplastic syndrome post allogeneic hematopoietic stem cell transplantation: a systematic review and meta-analysis.
BACKGROUND
Currently, there is no standard treatment for managing relapse in patients with acute myeloid leukemia and myelodysplastic syndrome (AML/MDS) after allogeneic hematopoietic cell transplantation. Venetoclax-based therapies have been increasingly used for treating post-transplantation relapse of AML. The aim of this systematic review and meta-analysis was to evaluate the efficacy and adverse events of Venetoclax combined with hypomethylating agents (HMAs) for AML/MDS relapse post-transplantation.
METHODS
We searched PubMed, Web of Science, Excerpta Medica Database, Cochrane Library, and Clinical. gov for eligible studies from the inception to February 2022. The Methodological Index for Non-Randomized Studies was used to evaluate the quality of the included literatures. The inverse variance method calculated the pooled proportion and 95% confidence interval (CI).
RESULTS
This meta-analysis included 10 studies involving a total of 243 patients. The pooled complete response and complete response with incomplete blood count recovery rate of Venetoclax combined with HMAs for post-transplantation relapse in AML/MDS was 32% (95% CI, 26-39%, I = 0%), with an overall response rate of 48% (95% CI, 39-56%, I = 37%). The 6-month survival rate was 42% (95% CI, 29-55%, I = 62%) and the 1-year survival rate was 23% (95% CI, 11-38%, I = 78%).
CONCLUSION
This study demonstrated a moderate benefit of Venetoclax in combination with HMAs for patients with relapsed AML/MDS post-transplantation (including those who have received prior HMAs therapy), and may become one of treatment options in the future. Large-scale prospective studies are needed to confirm the potential benefit from venetoclax combined with HMAs.

Efficacy of epigenetic agents for older patients with acute myeloid leukemia and myelodysplastic syndrome in randomized controlled trials: a systematic review and network meta-analysis.
Myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML) are hematologic malignancies that mostly affect the elderly and have poor prognoses. Mutations in epigenetic regulatory genes cause AML/MDS through changes in DNA methylation and histone modifications. Some epigenetic agents are used in patients with AML and MDS. However, most studies have focused on azacitidine (AZA) or decitabine (DEC), and few studies have been conducted on combination therapies or other epigenetic therapies. This network meta-analysis (NMA) aimed to compare the efficacy of epigenetic agents overall in patients with AML and MDS. A systematic review and NMA of all available II-III phase randomized controlled trials (RCTs) comparing epigenetic agents were performed. The Embase and PubMed databases were searched for relevant studies. The Bayesian model was used in the NMA, and the surface under the cumulative ranking curve (SUCRA) was used to rank comparisons. The primary endpoint was overall survival (OS), and the secondary endpoints were complete response (CR) and partial response (PR). OS was extended by AZA + venetoclax (SUCRA 0.94) in patients with AML and MDS. DEC (SUCRA 0.78) relatively improved CR and PR. In this study, AZA-related treatment was relatively effective in improving the OS of patients with AML and MDS, and DEC-related treatment showed a relatively high effect on CR and PR. The protocol for this systematic review was registered with the International Prospective Register of Systematic Reviews (CRD42022303601).

Meta-Analysis Review
BACKGROUND
Arsenic trioxide (ATO) might be effective for myelodysplastic syndrome (MDS) by apoptosis induction and demethylation. But ATO has not been widely recommended for small sample and conflicting conclusion of existing trials. This review aimed to systematically evaluate the efficacy of regimens containing ATO for the MDS and explore optimal combination.
METHOD
Randomized clinical trials (RCTs) about ATO regimens were retrieved from China National Knowledge Infrastructure, Embase and PubMed. With odds ratio (OR) as the effect size, network meta-analysis (NMA) and component network meta-analysis (CNMA) were conducted by R and 'netmeta' package, after study selection, quality assessment and data extraction.
RESULT
Thirty-night RCTs were included with a total of 2125 patients, including 1235 treated by ATO containing regimen. With support therapy alone as reference, no inconsistency and heterogeneity were observed. Although NMA did not demonstrate better efficacy of ATO alone, the result of CNMA indicated that ATO was effective in the improvement of overall remission (ORR) [OR = 2.09(1.61, 2.71)] and complete remission (CR) [OR = 1.66(1.25, 2.21)]. Five ATO-containing regimens reported could effectively improve ORR, some of them benefit in CR or hematological improvement (HI) as well. ATO + Traditional Chinese Medicine (TCM), ATO + Thalidomide (T)+TCM, ATO + Chemotherapy (Chem)+T + TCM were regarded as the optimal combination, which improved both ORR, CR and HI in theory. ATO did not increase the risk of common adverse events compared to supportive therapy [(OR = 0.90(0.67, 1.21)].
CONCLUSION
ATO may be an effective and well-tolerant option for patients with myelodysplastic syndrome.

Myelodysplastic syndrome (MDS) may present with specific skin lesions, such as leukaemia cutis, which is a well known poor prognostic marker of leukaemia with a high risk of acute leukaemic transformation. However, less is known regarding non-specific cutaneous manifestations of MDS including the prevalence, types and their prognostic and therapeutic significance, which we aimed to determine through this systematic review. We searched electronic databases (PubMed, Medline and EMBASE) from inception up to 26 January 2023 for studies reporting cutaneous manifestations of MDS. Eighty eight articles (case reports = 67, case series = 21), consisting of 134 patients were identified. We identified 6 common cutaneous manifestations: neutrophilic dermatoses ( = 64), vasculitis ( = 21), granulomatous ( = 8), connective tissue disease (CTD) ( = 7; composed of dermatomyositis ( = 5), cutaneous lupus erythematosus ( = 1), and systemic sclerosis ( = 1)), panniculitis ( = 4), immunobullous ( = 1), and other ( = 29). Cutaneous features either occurred at time of MDS diagnosis in 25.3%, preceding the diagnosis in 34.7% (range 0.5-216 months), or after diagnosis in 40.0% (range 1-132 months). Prognosis was poor (40.2% death) with 34.1% progressing to acute myeloid leukaemia (AML). 50% of those with MDS who progressed to AML had neutrophilic dermatoses ( = 0.21). Myelodysplastic syndrome was fatal in 39.2% of neutrophilic dermatoses (median time from onset of cutaneous manifestation: 12 months), 50% of vasculitis (7.5 months), 62.5% of granulomatous (15.5 months) and 14.3% of CTD (7 months). Recognition of patterns of cutaneous features in MDS will improve early diagnosis and risk stratification according to subtype and associated prognosis.

Review
Purpose To study the potential utility of danazol for treating patients with myelodysplastic syndromes, with a focus on efficacy and adverse effects (AEs). Methods MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus were searched for relevant publications from inception June 1, 1950, until June 28, 2022. The studies were screened by title and abstract, followed by full-text screening. The quality of the included studies was assessed via a prespecified set of questionnaires. Data on the efficacy measures and adverse outcomes were extracted and included in a descriptive summary. Results Nine studies consisting of 246 participants were included in our review. The overall quality of the included studies was fair. The age of the participants ranged from 61 to 78 years. In all 9 studies, more male patients had been enrolled than female patients. Overall, a proportion of patients in all the studies reported a desired major response to a danazol dose of 400 to 800 mg/day. Few studies did not observe any improvement in the platelet count. Elevated liver enzyme levels, weight gain, headache, dermatitis, and weakness were the most common AEs observed. One study reported a fatal intracerebral hemorrhage in 1 participant. Conclusions Danazol has been effective in increasing platelet count and hemoglobin level. Despite a few AEs, danazol is a safe drug for the treatment of patients with myelodysplastic syndromes.

Meta-Analysis Review
We conducted a systematic review and meta-analysis to evaluate outcomes after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) in TP53-mutated myelodysplastic syndromes (MDS). A literature search was performed on PubMed, Cochrane, Embase, and Clinicaltrials.gov. After screening 626 articles, eight studies were included. Data were extracted following the PRISMA guidelines and analyzed using the meta-package by Schwarzer et al. We analyzed 540 patients. The pooled median 3 (1-5) year overall survival was 21% (95% CI 0.08-0.37, I2=91%, n=540). The pooled relapse rate was 58.9% (95% CI 0.38-0.77, I2=93%, n=487) at a median of 1.75 (1-3) years. The pooled 4-year progression- free survival was 34.8% (95% CI 0.15-0.57, I2=72%, n=105). Outcomes of Allo-HSCT for TP53-mutated MDS patients remain poor, with 21% OS at three years; however, Allo-HSCT confers a survival advantage as compared to non-transplant palliative therapies. Our findings suggest the need to explore novel therapeutic agents in prospective clinical trials.

Review
BACKGROUND
Highly supported microRNAs (miRNAs) are key players in cancer development. Each of these miRNAs may act as an oncomir, a tumor-suppressor, or both in various cancers. Mir-151a-5p is believed to be one of these miRNAs with diverse roles. We have conducted this systematic review to clarify the role of mir-151a-5p in formation of various cancers.
METHODS AND MATERIALS
We searched for existing articles in PubMed, Web of Science, Cochrane, Scopus, and RNAcentral databases up to November 2022. A total of 23 articles were qualified and included in the present systematic review. This review is registered on JBI at https://jbi.global/systematic-review-register. Expression levels, diagnostic and prognostic values, biological processes, and targeted downstream genes are included.
RESULTS
Assembled data indicate the expression levels of mir-151a-5p vary from down- to up-regulated based on the type of the cancer. Its functional role depends on the genetic profile of cancerous tissue. Results mostly point to the oncogenic role of this miRNA in Pituitary adenomas, Acute Myeloid Leukemia (AML), Endometrial, Lung, Barrett's carcinogenesis, Colorectal, Myelodysplastic syndromes, Hepatocellular carcinoma and Breast cancers, as its inhibited targets seem to be controlling several signaling pathways, cell adhesion, and cell cycle. At the same time, tumor-suppressing role has also been observed only in Malignant Pleural Mesothelioma, Central Nerve System (CNS) lymphoma, Chronic Myeloid and Acute Lymphocytic Leukemia. Two types of cancers, prostate and colon, show contradictory results as there are studies supporting both up- and down-regulation in these cancers. Pituitary adenomas, Barrett's carcinogenesis and CNS lymphomas are top cancers diagnosed with mir-151-5p. However, prognostic feature is only applicable to Lung adenocarcinoma.
DISCUSSION
Based on the present findings and further studies in the future, mir-151a-5p may be used as diagnostic and prognostic biomarkers or even a therapeutic target in cancer studies.
