Epidemiology, treatment patterns, and disease burden of cytomegalovirus in hematopoietic cell transplant recipients in selected countries outside of Europe and North America: A systematic review.
BACKGROUND
Cytomegalovirus (CMV) disease impacts morbidity and mortality in hematopoietic cell transplant (HCT) recipients. This systematic review summarized data on the epidemiology, management, and burden of CMV post-HCT outside of Europe and North America.
METHODS
The MEDLINE, Embase, and Cochrane databases were searched for observational studies and treatment guidelines in HCT recipients across 15 selected countries from Asia-Pacific, Latin America, and Middle East (search period: 1 January 2011-17 September 2021). Outcomes included incidence of CMV infection/disease, recurrence, risk factors, CMV-related mortality, treatments, refractory, resistant CMV, and burden.
RESULTS
Of 2708 references identified, 68 were eligible (67 studies and one guideline; 45/67 studies specific to adult allogeneic HCT recipients). The rates of CMV infection and disease within 1 year of allogeneic HCT were 24.9%-61.2% (23 studies) and 2.9%-15.7% (10 studies), respectively. Recurrence occurred in 19.8%-37.9% of cases (11 studies). Up to 10% of HCT recipients died of CMV-related causes. In all countries, first-line treatment for CMV infection/disease involved intravenous ganciclovir or valganciclovir. Conventional treatments were associated with serious adverse events such as myelosuppression (10.0%) or neutropenia only (30.0%, 39.8%) and nephrotoxicity (11.0%) (three studies), frequently leading to treatment discontinuation (up to 13.6%). Refractory CMV was reported in 2.9%, 13.0%, and 28.9% of treated patients (three studies) with resistant CMV diagnosed in 0%-10% of recipients (five studies). Patient-reported outcomes and economic data were scarce.
CONCLUSION
The incidence of CMV infection and disease post-HCT is high outside of North America and Europe. CMV resistance and toxicity highlight a major unmet need with current conventional treatments.

Meta-Analysis Review
BACKGROUND
Currently, gastric cancer (GC) and colorectal cancer (CRC) are the most common causes of cancer-related mortality worldwide. Gut microbiota is closely related to the occurrence of GC and CRC and the efficacy of chemotherapy. This study is aimed at evaluating the efficacy and safety of herbal formulas with the function of gut microbiota regulation (HFGMR) in the treatment of GC and CRC and to assess the quality of the synthesized evidence.
METHODS
A comprehensive search was performed on eight electronic databases, PubMed, EMBASE, CENTRAL, Web of Science, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, Wanfang database, Chinese Scientific Journals Database, and two registries, Chinese Clinical Trial Registry and ClinicalTrials.gov, from their initiation to January 2022. Randomized controlled trials (RCTs) studying the therapeutic effects of HFGMR were included. We used Stata 16 for data synthesis and Risk of Bias 2 (RoB 2) for methodological quality evaluation and assessed the quality of the synthesized evidence in the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach.
RESULTS
Fifty-three RCTs involving 4,478 patients were included. These trials involve seven herbal formulas that could regulate the gut microbiota of , , , , and . The meta-analysis results were subgrouped to three different stages in GC and CRC. 1) For the perioperative stage, HFGMR combined with conventional therapy could shorten the time to bowel sound recovery by 1.63 h [mean difference (MD) = -1.63, 95% confidence interval (CI) (-2.62, -0.65)], the time to first flatus by 9.69 h [MD = -9.69, 95% CI (-10.89, -8.48)], and the duration of hospitalization by 2.91 days [MD = -2.91, 95% CI (-4.01, -1.80)] in GC. There were no significant differences in outcomes of gastrointestinal function recovery and adverse events in CRC. 2) For postoperative patients, combined with adjuvant chemotherapy, HFGMR could decrease the incidence of diarrhea, nausea and vomiting, anorexia, and peripheral neurotoxicity in GC; boost Karnofsky performance status (KPS) improvement rate [risk ratio (RR) = 1.96, 95% CI (1.38, 2.79)]; and decrease the incidence of leucopenia and nausea and vomiting in CRC. 3) For advanced stage, HFGMR can significantly improve the objective response rate (ORR) [RR = 1.35, 95% CI (1.19~1.53)], disease control rate (DCR) [RR = 1.14, 95% CI (1.05~1.23)], and KPS improvement rate [RR = 1.56, 95% CI (1.17, 2.09)] and decrease the incidence of leucopenia, neutropenia, anemia, nausea and vomiting, diarrhea, and fatigue in GC. There were no significant differences in ORR [RR = 1.32, 95% CI (0.94~1.86)] and DCR [RR = 1.22, 95% CI (0.99~1.50)], but they can improve the KPS response rate [RR = 1.62, 95% CI (1.13, 2.32)] and decrease the incidence of myelosuppression, nausea and vomiting, diarrhea, and hepatic and renal dysfunction in CRC.
CONCLUSION
This study indicates that herbal formulas that could regulate the composition and proportion of gut microbiota have a positive effect in three stages (perioperative, postoperative, and advanced) of GC and CRC. They could promote the recovery of postoperative gastrointestinal function, increase tumor response, improve performance status, and reduce the incidence of adverse events. Herbal formulas exerted anti-cancer efficacy through multiple mechanisms and pathways; among them, the regulation of gut microbiota has not been paid enough attention. To further support the conclusion and better understand the role of gut microbiota in the treatment of GC and CRC, more rigorously designed, large-scale, and multicenter RCTs that focus on herbal formulas and gut microbiota are needed in the future.

BACKGROUND
In the present systematic literature review, we sought to describe the burden and treatment practices of adult acute lymphoblastic leukemia (ALL) in India, which reflect the realities and outcomes in a middle-income country.
MATERIALS AND METHODS
We conducted a search for reported studies using terms such as "adult ALL," "epidemiology," and "treatment" in the Medline, Embase, Cochrane, and other database sources. We obtained 249 articles and 18 conference abstracts reported until December 2019. A total of 40 studies were selected to qualitatively summarize the data.
RESULTS
The proportion of ALL among adult patients diagnosed with acute leukemia at reporting institutions from 16 Indian studies ranged from 7.3% to 57.8%. Most studies were performed in Northern India (n = 12), had a male preponderance (range, 57%-80%), and had a predominance of B-ALL (range, 65.2%-75.9%). The treatment protocols used for ALL included MCP-841, BFM (Berlin-Frankfurt-Münster)-90, chemotherapy plus a tyrosine kinase inhibitor, GMALL (German Multicenter Study Group for Adult Acute Lymphoblastic Leukemia), and hyper-CVAD (cyclophosphamide, vincristine, doxorubicin, dexamethasone). The complete remission rates and median overall survival for these protocols ranged from 46.7% to 91.4% and 7 to 46 months, respectively. The overall relapse rates were 24.3% to 57.1% within median time of 9 to 24 months, with bone marrow the most frequent relapse site. After relapse, most patients had chosen palliative therapy (range, 78.7%-96.0%). The major treatment-related toxicities included neutropenia, myelosuppression, and infection.
CONCLUSIONS
The results from Indian studies on adult ALL are heterogeneous, reporting a diverse incidence and poor overall outcomes using varied non-contemporaneous treatment protocols adapted from the developed world. A comprehensive countrywide approach to diagnosis, treatment, and follow-up and the potential incorporation of novel therapies could improve the prognosis and outcomes of adult ALL in India.

Meta-Analysis Review
Efficacy and safety profile of linezolid in the treatment of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis: a systematic review and meta-analysis.
BACKGROUND
Treatment options for drug-resistant tuberculosis are still limited. Linezolid has been recommended for treatment of patients with multidrug-resistant (MDR) or extensively-drug-resistant (XDR) tuberculosis, although uncertainties remain regarding its safety and tolerability in these circumstances.
OBJECTIVE
To systematically evaluate the existing evidence regarding the efficacy and tolerability of linezolid in the treatment of MDR or XDR tuberculosis.
METHODS
We conducted a systematic review and meta-analysis in accordance with the PRISMA guidelines. Searches were conducted in PubMed, Web of Science and EMBASE followed by direct search of abstracts in the International Journal of Tuberculosis and Lung Disease to retrieve primary studies published between January 2000 and January 2016 assessing linezolid efficacy and safety in the treatment of drug-resistant TB. We evaluated the occurrence of outcomes including culture conversion, treatment success and incidence of adverse events such as myelosuppression and neuropathy.
RESULTS
Twenty-three (23) studies conducted in fourteen (14) countries and involving 507 patients were retrieved. Only 1 randomized controlled trial was identified and none of the identified studies involved participants from Africa. The pooled proportion for treatment success was 77.36 % (95 % CI = 71.38-82.83 %, I(2) = 37.6 %) with culture conversion rate determined as 88.45 % (95 % CI = 83.82-92.38 %, I(2) = 45.4 %). There was no strong evidence for both culture conversion (p = 0.0948) and treatment success (p = 0.0695) between linezolid daily doses ≤ 600 and > 600 mg. Only myelosuppression showed a strong statistical significance (p < 0.0001) between dose comparisons. The incidence of neuropathy and other adverse events leading to permanent discontinuation of linezolid also showed no significance upon dose comparisons (p = 0.3213, p = 0.9050 respectively).
CONCLUSION
Available evidence presents Linezolid as a viable option in the treatment of MDR/XDR TB although patients ought to be monitored closely for the incidence of major adverse events such as myelosuppression and neuropathy. Additionally, highly powered randomized controlled trials including participants from endemic regions are urgently needed to better inform the magnitude and significance of Linezolid treatment effect in MDR and XDR TB patients.

INTRODUCTION
High-dose methotrexate (HDMTX) therapy poses challenges in various neoplasms due to individualized pharmacokinetics and associated adverse effects. Our purpose is to identify early risk factors associated with HDMTX-induced toxicities, paving the way for personalized treatment.
AREAS COVERED
A systematic review of PubMed and Cochrane databases was conducted for articles from inception to July 2023. Eligible studies included reviews, clinical trials, and real-world analyses. Irrelevant studies were excluded, and manual searches and citation reviews were performed. Factors such as MTX exposure, drug interactions, demographics, serum albumin, urine pH, serum calcium, and genetic polymorphisms affecting MTX transport (e.g. SLCO1B1), intracellular folate metabolism (MTHFR), cell development (ARID5B), metabolic pathways (UGT1A1, PNPLA3), as well as epigenetics were identified.
EXPERT OPINION
This comprehensive review aids researchers and clinicians in early identification of HDMTX toxicity risk factors. By understanding the multifaceted risk factors associated with hematologic malignancies, personalized treatment approaches can be tailored to optimize therapeutic outcomes.

Meta-Analysis Review
The short- and long-term survival of hyperthermic intraperitoneal chemotherapy (HIPEC) in the advanced gastric cancer with/without peritoneal carcinomatosis: a systematic review and meta-analysis of randomized controlled trials.
To evaluate the short- and long-term survival of hyperthermic intraperitoneal chemotherapy (HIPEC) in the patients with advanced gastric cancer (AGC) through randomized controlled trials (RCTs). We analyzed the endpoints of AGC patients including 1-, 2-, 3-, and 5-year overall survival (OS), intestinal anastomotic leakage, myelosuppression, nausea and vomiting from included studies. And we retrieved RCTs from medical literature databases. Risk ratios (RR) was used to calculated the endpoints. Totally, we retrieved 13 articles (14 trial comparisons) which contained 1091 patients. They were randomized to HIPEC group and control group. The results showed that there was no significant differences in survival rates between HIPEC group and control group at 1-, 2- and 3-year follow-up, while a statistical significant overall survival effect was found at the 5-year follow-up [RR: 1.20, 95% CI 1.01 to 1.43, I = 0.0%]. And there is no significant difference in the risk of intestinal anastomotic leakage, myelosuppression and nausea and vomiting. Compared with the control group, HIPEC could improve the long-term OS without increasing the risk of adverse effect in AGC patients with/without peritoneal carcinomatosis, but there was no benefit at short-term OS.

Review
BACKGROUND
Aidi injection (ADI) is being used widely for breast cancer in China. However, the efficacy and safety of it need to be summarized. We conducted a systematic review and meta-analysis to compare ADI and non-ADI treatment for advanced breast cancer.
METHODS
We searched PubMed, EMBASE, CNKI, SinoMed, and CENTRAL from inception to Jan 2020 for randomized controlled trials (RCTs) with diagnosis of advanced breast cancer that compared the efficacy of ADI with non-ADI treatment. Two researchers screened the literature, extracted data, and evaluated risk of bias separately. The primary outcomes were overall response rate (ORR) and disease control rate (DCR). The secondary outcomes included the QOL, immune cells, and adverse events. Review Manager software was used for estimating risks of bias of included studies, data analysis, and plotting. The sensitivity analysis and the publication bias test were performed using the language. and chi-square tests were used to estimate heterogeneity. If > 0.1 or < 40%, the fixed-effect model meta-analysis was performed. A random or fixed-effect analysis was used depending on the heterogeneity testing. Weighted mean difference (WMD) or standard mean difference (SMD) was used for analysis of continuous data, and the rate ratio (RR) was calculated for the dichotomous variable, respectively.
RESULTS
We included 14 studies with 1006 patients diagnosed as advanced breast cancer in total. The pooled effect showed that ADI increased ORR in advanced BC patients as an add-on therapy with little heterogeneity ( = 1.14, 95% CI 1.03-1.27). DCR in BC patients could not be improved by ADI. ADI improved the KPS score in BC patients compared with chemotherapy alone (MD = 3.26, 95% CI 1.74-4.78). There were no improvements on immune markers except CD4/CD8 and NK%. Serum tumor markers CEA and CA153 were decreased while treated with ADI, but only one trial was involved. ADI decreased the numbers of myelosuppression in advanced BC patients, and AST, ALT, -GT, and CK-MB were all decreased. The sensitivity evaluation indicated that the result of the pooled effect size had good stability.
CONCLUSION
This meta-analysis suggested that based on the existing evidence, treatment with ADI significantly changed the ORR of patients with advanced BC and improved their quality of life with few side effects. However, more randomized trials involving larger samples should be considered, and detailed mechanisms are needed to be uncovered.

Review
Intrathoracic infusion therapy with Lentinan and chemical irritants for malignant pleural effusion: a systematic review and meta-analysis of 65 randomized controlled trials.
BACKGROUND
Aderivative of Shiitake mushrooms, Lentinan is used to control malignant pleural effusion (MPE) through intrathoracic infusion.
PURPOSE
To determine the clinical response, survival and safety of Lentinan plus chemical irritants, and the optimal combinations with chemical irritants, indication, threshold and optimal regimen for achieving the desired responses.
STUDY DESIGN
We performed a new systematic review and meta-analysis following the PRISMA guidelines.
METHODS
We collected all randomized controlled trials (RCTs) regarding Lentinan plus chemical irritants from Chinese and English electronic databases (from inception until March 2019). We evaluated their bias risk, synthesized data using meta-analysis, and summarized evidence quality following the Grades of Recommendation Assessment, Development and Evaluation approach.
RESULTS
We included 65 RCTs involving 4,080 patients and nine chemical irritants. Most trials had unclear bias risk. Lentinan with cisplatin significantly improved complete response [Risk ratio (RR) = 1.68, 95% confidence intervals (CI) (1.51 to 1.87), p < 0.00001, Fig.3a] and quality of life [RR = 1.51 95% CI (1.41 to 1.62), p < 0.00001, Fig.4], and decreased the risk of treatment failure, myelosuppression, gastrointestinal reaction, and chest pain. For patients with moderate to large volume of the pleural effusion, primary treatment, KPS score ≥ 50-60, or anticipated survival time ≥ 3months, Lentinan (3-4 mg/time, once a week for three to four times) withcisplatin (30-40 mg/m or 50-60 mg/m) significantly improved complete response and decreased failure. Most results were robust and moderate quality.
CONCLUSION
The results suggest that Lentinan with chemical irritants, especially cisplatin is beneficial to the patient with MPE, and provide evidence for the indication, threshold, and optimal regimen that may achieve success and decrease failure.

Review
This study focuses on the use of thiopurines for treating inflammatory bowel diseases (IBD). These drugs undergo enzymatic changes within the body, resulting in active and inactive metabolites that influence their therapeutic effects. The research examines the role of genetic polymorphisms in the enzyme thiopurine S-methyltransferase (TPMT) in predicting the therapeutic response and adverse effects of thiopurine treatment. The TPMT genotype variations impact the individual responses to thiopurines. Patients with reduced TPMT activity are more susceptible to adverse reactions (AEs), such leukopenia, hepatotoxicity, pancreatitis, and nausea, which are common adverse effects of thiopurine therapy. The therapeutic monitoring of the metabolites 6-thioguanine nucleotides (6-TGN) and 6-methyl mercaptopurine (6-MMP) is proposed to optimize treatment and minimize AEs. Patients with higher 6-TGN levels tend to have better clinical responses, while elevated 6-MMP levels are linked to hepatotoxicity. Genotyping for TPMT before or during treatment initiation is suggested to tailor dosing strategies and enhance treatment efficacy while reducing the risk of myelosuppression. In conclusion, this study highlights the importance of considering genetic variations and metabolite levels in optimizing thiopurine therapy for IBD patients, focusing on balance therapeutic efficacy with the prevention of adverse effects and contributing to personalized treatment and better patient outcomes.

Meta-Analysis Review
Efficacy and safety of doublet versus single agent as salvage treatment for metastatic breast cancer pretreated with anthracyclines and taxanes: a systematic review and meta-analysis.
AIM
To perform a systematic review and meta-analysis of randomized controlled trials to compare the efficacy and safety of doublet versus single agent as salvage treatment for pretreated metastatic breast cancer.
METHODS
A comprehensive literature search was performed to identify relevant randomized controlled trials (RCTs). All clinical studies were independently identified by two authors for inclusion. Demographic data, treatment regimens, objective response rate (ORR), and progression-free survival (PFS) and overall survival (OS) were extracted and analyzed using Comprehensive MetaAnalysis software (Version 2.0).
RESULTS
Thirteen RCTs involving 4878 pretreated metastatic breast cancer patients were ultimately identified. The pooled results demonstrated that doublet combination therapy significantly improved ORR (RR 1.13, 95% CI: 1.01-1.27, p < .001) and PFS (hazard ration [HR] 0.83, 95% CI: 0.73-0.96, p = .011), but not OS (HR 0.93, 95% CI: 0.86-1.01, p = .065). Similar results were observed in sub-group analysis according to treatment regimens. Additionally, more incidences of grade 3 or 4 myelosuppression toxicities nausea and fatigue were observed in doublet combination therapy.
CONCLUSIONS
In comparison with a single agent alone, doublet combination therapy as salvage treatment for pretreated metastatic breast cancer patients significantly improves ORR and PFS, but not OS. Further studies are recommended to identify patients who will most likely benefit from the appropriate doublet combination therapy.
