Review
BACKGROUND
Chronic lymphocytic leukemia (CLL) can transform into fast growing lymphoma for diffuse large B-cell lymphoma (DLBCL) called Richter's syndrome (RS), which is commonly related to an existence of large B-cells with equal or larger size than macrophage nuclei or more than twice those of normal lymphocyte. We conducted a systematic review of the existing literature to assess the clinical efficacy of auto-HCT for patients with RS.
METHODS
We searched 4 main databases; EMBASE, Google Scholar, Scopus, PubMed and Web of Science and was done on December 26, 2021. All analyses in this study were performed by Stata software and this review was reported in accordance with PRISMA 2020.
RESULTS
Data was extracted from 4 articles; the total number of patients was reported to be 110. Based on the meta-analysis findings, pooled overall survival rate was 56.36% (95%CI= (46.98-65.31). In figure 2, the forest plot of combined results is shown.
CONCLUSION
Despite the use of common treatment regimens such as chemo immunotherapy and the availability of novel therapies including B-cell receptor inhibitors and rituximab-cyclophosphamide-hydroxydaunorubicin-Oncovin-prednisone (CHOP-R) regimen, the status of disease progression and recovery in RS cases is still not strong enough.

Meta-Analysis
The safety of radium-223 combined with new-generation hormonal agents in bone metastatic castration-resistant prostate cancer: a systematic review and network meta-analysis.
Patients with bone metastatic castration-resistant prostate cancer (mCRPC) might benefit from radium-223 (Ra) combined with new-generation hormonal agents (NHAs) in terms of survival and quality of life (QoL). However, the safety of combination therapies remains unclear. Therefore, we aimed to perform a network meta-analysis by reviewing the literature about the combination of Ra with abiraterone acetate plus prednisone (AAP) or enzalutamide and to evaluate the safety of combination therapy in bone mCRPC patients. Ultimately, ten studies (2835 patients) were selected, including four randomized controlled trials (RCTs), five retrospective cohort studies, and one single-arm study. Overall, there was no difference in the incidence of fracture between the Ra+NHA combination group and the Ra monotherapy group (odds ratio [OR]: 1.46, 95% confidence interval [CI]: 0.91-2.34, P = 0.66), but the incidences in both the Ra+NHA combination group (OR: 3.22, 95% CI: 2.24-4.63, P < 0.01) and the Ra monotherapy group (OR: 2.24, 95% CI: 1.23-4.08, P < 0.01) were higher than that in the NHA monotherapy group. However, in the meta-analysis involving only RCTs, there was no difference between the Ra monotherapy group and the NHA monotherapy group (OR: 1.14, 95% CI: 0.22-5.95, P = 0.88), while the difference between the Ra+NHA combination group and the NHA monotherapy group remained significant (OR: 3.22, 95% CI: 2.24-4.63, P < 0.01). Symptomatic skeletal events (SSEs), SSE-free survival (SSE-FS), all grades of common adverse events (AEs), and ≥grade 3 AEs among all groups did not show any significant difference. Our results indicate that the combination of Ra with NHAs was well tolerated in bone mCRPC patients compared to Ra monotherapy, even though the incidence of fracture was higher in patients who received Ra than that among those who received NHA monotherapy. More evidence is needed to explore the safety and efficiency of Ra combination therapies.

Meta-Analysis Review
BACKGROUND
Acute pyelonephritis is a common infection in children that may cause renal scarring. The aim of this systematic review and meta-analysis was to analyse the use of corticosteroid treatment to prevent renal scarring.
METHODS
We searched the PubMED, SCOPUS, Cochrane CENTRAL and Web of Science databases in June 2022 for (corticosteroid* or dexamethasone or prednisolone* or prednisone* or hydrocortisone*) AND pyelonephritis. Randomised controlled trials focusing on children were included. The intervention was corticosteroid treatment with antibiotics compared to antibiotics with or without a placebo. The main outcome was the presence of renal scars on dimercaptosuccinic acid scanning at follow-up. The evidence quality was assessed using the GRADE methodology and risk of bias 2.0 tool. We calculated the risk ratio (RR), absolute risk difference (RD) with 95% confidence intervals (CI) and the number needed to treat (NNT). We applied a fixed effects model due to low heterogeneity.
RESULTS
We screened 872 abstracts and included five full texts. Renal scarring at follow-up was found in 31/220 (14.1%) patients in the corticosteroid groups and 76/278 (27.3%) in the control groups (RR 0.65, CI 0.44-0.96, RD - 13.2%, NNT 8). The evidence quality was moderate. Two studies reported adverse events with no differences between the groups. The risk of bias analysis showed some concerns in four studies.
CONCLUSION
We found moderate quality evidence that adjuvant corticosteroid treatment could prevent renal scarring. Adverse events were insufficiently reported, and more research on their effectiveness and harm is therefore needed before using corticosteroids in clinical settings.

Meta-Analysis Review
CONTEXT
Rheumatoid arthritis (RA) is a systemic autoimmune disease that commonly affects joints. Although many treatment options exist, the most common, disease-modifying antirheumatic drugs (DMARDs), have been associated with pulmonary infections. These types of infections (specifically pneumonia) can be detrimental to RA patients. This leads providers to utilize other treatment modalities such as glucocorticoids (GCs). GCs are commonly utilized to treat RA; however, the role of GCs in the onset of pneumonia in RA patients is not fully understood.
OBJECTIVES
The goal of this study was to systematically review and statistically analyze pooled data documenting pneumonia as an adverse event in RA patients on DMARDs as a monotherapy vs RA patients on DMARDs and GCs as combination therapy utilizing the Population, Intervention, Comparison, and Outcomes (PICO) framework.
METHODS
On August 1, 2021, a search was conducted and completed on six databases: Embase, MEDLINE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, International Pharmaceutical Abstracts (IPA), and ClinicalTrials.gov. A total of 12 researchers were involved with the search and screening of articles (K.E., P.R.; V.A., D.P.C.; C.B., D.C.; T.A., E.S.; S.H., L.B.; K.S., C.S.). Search terms were identified utilizing Medical Subject Headings (MeSH) and Emtree and included "glucocorticoids," "rheumatoid arthritis," "pneumonia," and "respiratory tract infections," Inclusion criteria included human subjects over the age of 18 with seropositive RA, on a combination of GC (prednisone, methylprednisolone, or prednisolone) with DMARD (methotrexate [MTX], hydroxychloroquine [HCQ], or sulfasalazine [SSZ]) and developed pneumonia of bacterial, viral, or fungal origin. The control groups were on a DMARD monotherapy regimen. Articles were excluded if they were not in English, had less than 20 participants, were case reports or literature reviews, included animal subjects, and did not adhere to the established PICO framework. Five teams of two researchers individually sorted through abstracts of articles based on the inclusion and exclusion criteria. The same teams individually sorted through full-text articles of selected abstracts based on the same criteria. Conflicts between each team were resolved by a separate researcher. Odds ratios were utilized to quantify the effect sizes of combined studies from a random effects model. Chi-square tests and I2 statistics were utilized to analyze heterogeneity.
RESULTS
A total of 3360 articles were identified from all databases, and 416 duplicate articles were removed. Thus, a total of 2944 articles abstracts were screened, of which 2819 articles either did not meet the inclusion criteria or did meet the exclusion criteria. A total of 125 articles were retrieved and assessed for full-text eligibility, of which only three observational articles were included for meta-analysis. Statistical results revealed that patients treated with DMARDs monotherapy are 95% (95% CI: 0.65-0.99) less likely to develop pneumonia compared to patients treated with a DMARD and GCs (p=0.002).
CONCLUSIONS
Our data suggest that RA patients have a higher probability of developing pneumonia on combination therapy with GCs, compared to monotherapy with DMARDs. To our knowledge, our findings are the first to systematically review and statistically evaluate the relationship between the use of GCs and show an increased chance of developing pneumonia.

Meta-Analysis
INTRODUCTION
Radioactive iodine (RAI) therapy is a critical component in the post-surgical management of thyroid cancer patients, as well as being a central therapeutic option in the treatment of hyperthyroidism. Previous work suggests that antithyroid drugs hinder the efficacy of RAI therapy in patients. However, the effects of other background medications on RAI treatment efficacy have not been evaluated. Therefore, we performed a systematic review and meta-analysis investigating the potential off-target effects of medication on RAI therapy in patients with thyroid cancer and hyperthyroidism.
METHODS
Systematic review and meta-analysis according to the 2020 PRISMA guidelines. Databases searched: MEDLINE, EMBASE and Cochrane Library for studies published between 2001 and 2021.
RESULTS
Sixty-nine unique studies were identified. After screening, 17 studies with 3313 participants were included. One study investigated thyroid cancer, with the rest targeted to hyperthyroidism. The majority of studies evaluated the effects of antithyroid drugs; the other drugs studied included lithium, prednisone and glycididazole sodium. Antithyroid drugs were associated with negative impacts on post-RAI outcomes (n = 5 studies, RR = 0.81, p = 0.02). However, meta-analysis found moderate heterogeneity between studies (I2 = 51%, τ2 = 0.0199, p = 0.08). Interestingly, lithium (n = 3 studies), prednisone (n = 1 study) and glycididazole (n = 1 study) appeared to have positive impacts on post-RAI outcomes upon qualitative analysis.
CONCLUSION
Our systematic review strengthens previous work on antithyroid medication effects on RAI, and highlights that this field remains under researched especially for background medications unrelated to thyroid disease, with very few papers on non-thyroid medications published.

RATIONALE
Chronic graft versus host disease (cGVHD) is a systemic immune-mediated complication that occurs in approximately half of patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HCT), and remains the leading cause of late morbidity and mortality. cGVHD involves a heterogeneous group of organic manifestations, many of which mimic autoimmune diseases such as scleroderma, primary biliary cholangitis, Sjögren syndrome and polymyositis.
PATIENT CONCERNS
A 60-years-old female with a history of allo-HCT developed de novo cGVHD 11 months after allo-HCT with isolated liver involvement. The patient presented with jaundice, cytolysis, cholestasis and concomitant acute digital ischemia. Liver biopsy and autoimmunity tests were performed and were found to be compatible with immune-mediated liver damage. Nailfold capillaroscopy revealed microangiopathy, characterized by avascular areas and some enlarged capillaries resembled an early systemic sclerosis pattern.
DIAGNOSIS
Biliary cholangitis-like and digital ischemia related to cGVHD.
INTERVENTIONS
The patient was treated with high-dose prednisone and ursodeoxycholic acid, and extracorporeal photopheresis. The patient required hospital admission for administration of intravenous prostacyclin due to refractory Raynaud syndrome.
OUTCOMES
After 6 to 8 weeks, the patient achieved a good response, with evident clinical improvement and progressive normalization of liver function.
LESSONS
cGVHD is a multiorgan pathological condition, and this case emphasizes that a multidisciplinary team, including rheumatologists, should be involved in the follow-up of allo-transplant patients to ensure that the clinical complications are adequately addressed. Early intervention is critical for improving patient' prognosis.In addition, we performed a systemic literature review based on published case articles on hepatic cGVHD and digital ischemia published up to August 2022. To the best of our knowledge, this is the first reported case of such an association.

Review
OBJECTIVE
Granulomatosis with polyangiitis is an unusual multisystemic inflammatory disease, with vasculitis of small- and medium-sized vessels, with a predilection for upper lower airways and kidneys. The etiology remains unknown although it may originate from different stimuli, in genetically susceptible patients.
MATERIALS AND METHODS
A detailed database search was performed. The variables were demographics, localization, histopathological findings, antineutrophil cytoplasmic autoantibody, cytoplasmic (c-ANCA) tests, treatment, and follow-up.
RESULTS
Fifty-two cases were identified; the mean age was 49.6 years, with a range from 6 to 87 years. It was most frequently seen in females (57.7%). The most common race was white (59.6%). The most frequent location was in the maxillary gingiva (28.8%), followed by both the upper and lower gingiva (19.2%). The most common clinical presentation was "strawberry gingivitis" (61.5%). The main symptom was pain, in 50%. Regarding the c-ANCA test, it was positive in 71.2% of cases. The most common therapy was prednisone and cyclophosphamide, utilized in 51.9%. The average follow-up was 23.6 months, and 88.5% of patients were still alive at follow-up.
CONCLUSION
The diagnosis initially was difficult to establish, an early diagnosis and treatment are mandatory. If untreated the disease can be associated with morbidity and mortality. For the oral clinician, this disease needs to be addressed in the differential diagnosis of oral lesions.

Cardiovascular adverse events associated with cyclophosphamide, pegylated liposomal doxorubicin, vincristine, and prednisone with or without rituximab ((R)-CDOP) in non-Hodgkin's lymphoma: A systematic review and meta-analysis.
The (R)-CDOP combination regimen, based on pegylated liposomal doxorubicin, is increasingly used for elderly patients with non-Hodgkin's lymphoma. However, the cardiotoxicity and efficacy of the (R)-CDOP regimen compared with conventional anthracyclines have not been demonstrated in the general population. Therefore, this systematic review and meta-analysis evaluated the risk of cardiotoxicity and efficacy associated with the (R)-CDOP regimen in patients with non-Hodgkin's lymphoma. PubMed, Embase, Cochrane Library, CNKI, WanFang Database, and VIP were searched. The search covered the period from the start of the clinical use of (R)-CDOP to April 2022. We searched the literature for cardiovascular adverse events associated with (R)-CDOP in non-Hodgkin's lymphoma. The data were analyzed using R 4.2.0 and Stata 12.0. From the included studies, the important findings were as follows: total cardiovascular event rate, 7.45% (95% confidence interval [CI] = 4.86%-10.44%); non-serious cardiovascular adverse event rate, 6.48% (95% CI = 3.70%-9.8%); serious cardiovascular adverse event rate, 0.67% (95% CI = 0.00%-2.12%); heart failure rate, 0.55% (95% CI = 0.00%-1.93%); rate of treatment discontinuation attributable to left ventricular dysfunction or heart failure, 0.02% (95% CI = 0.00%-0.57%); and cardiovascular death rate, 0.00% (95% CI = 0.00%-0.37%). Compared with the (R)-CHOP regimen, the (R)-CDOP regimen reduced the risk of cardiovascular events, including total cardiovascular adverse events (odds ratio [OR] = 0.161, 95% CI = 0.103-0.251, < 0.001, and NNT = 3.7), non-serious cardiovascular adverse events (OR = 0.171, 95% CI = 0.093-0.314, < 0.001, and NNT = 3.6), serious cardiovascular adverse events (OR = 0.252, 95% CI = 0.119-0.535, < 0.001, and NNT = 6.8), and heart failure (OR = 0.294, 95% CI = 0.128-0.674, = 0.004, and NNT = 9.5). To evaluate the survival benefits, we compared (R)-CDOP and (R)-CHOP regimens. We found that the (R)-CDOP regimen was no less efficacious, including complete remission (CR) (OR = 1.398, 95% CI = 0.997-1.960, and = 0.052), partial response (PR) (OR = 1.631, 95% CI = 1.162-2.289, and = 0.005), objective response rate (ORR) (OR = 2.236, 95% CI = 1.594-3.135, and < 0.001), stable disease (SD) (OR = 0.526, 95% CI = 0.356-0.776, and = 0.001), and progressive disease (PD) (OR = 0.537, 95% CI = 0.323-0.894, and = 0.017). Our findings suggested that the (R)-CDOP regimen had a lower risk of cardiovascular adverse events in non-Hodgkin's lymphoma than the (R)-CHOP regimen, demonstrating its safety with regard to cardiotoxicity. In addition, this study found the (R)-CDOP regimen was no less efficacious than the (R)-CHOP regimen in the treatment of non-Hodgkin's lymphoma. These findings need to be validated by higher-quality research because of the limited number and quality of included studies.

Revista Espanola de Quimioterapia :... Feb 2023To determine the prevalence of CMV reactivation in a population admitted for severe COVID-19 to a general hospital.
OBJECTIVE
To determine the prevalence of CMV reactivation in a population admitted for severe COVID-19 to a general hospital.
METHODS
Point prevalence study in all hospitalized patients with severe COVID-19 (admitted either to general wards or ICU). Determination of the presence of CMV DNA in circulating blood. COVID-19 was confirmed in patients with compatible clinical manifestations, usually with pneumonia and a positive nasopharyngeal PCR test.
RESULTS
We included 140 hospitalized patients with COVID-19 who consented to participate. A total of 16 patients (11.42%), had circulating CMV-DNA in peripheral blood at the time of the study. Patients with positive CMV viral load were mainly ICU patients (11/37 -29,7%) and only 5/103 cases (4,85%) were hospitalized into general wards. The accumulated doses of corticosteroids (prednisone equivalents) in the study day were (median and IQR) 987.50 mg (396.87-2,454.68) and 187.50 mg (75.00-818.12) respectively in CMV positive and negative patients (p < 0.001). A significant proportion of CMV positive patients were discovered because of the study and were clinically unsuspected by their physicians. The coinfected COVID-CMV positive population had a higher risk of accumulated secondary nosocomially-acquired infections and a worse prognosis.
CONCLUSIONS
CMV reactivation should be systematically searched in patients in COVID-19 cases admitted to the ICU.

Review
OBJECTIVES
Several therapies are available for the treatment of advanced/metastatic prostate cancer (PC). However, the systematic assessment of evidence pertaining to the use of these therapies in Asian patients is lacking.
METHODS
A systematic literature review (SLR) was conducted using PubMed/Medline search in May 2021 to identify the randomized/nonrandomized controlled trials (RCTs/non-RCTs) and real-world observational studies (prospective/retrospective). Only studies published as full manuscripts in English were included if reporting the efficacy, effectiveness, and/or safety of treatments in Asian patients with advanced/metastatic PC.
RESULTS
Of the 1,898 retrieved publications, 24 studies were included. These studies had patients with nonmetastatic castration-resistant PC (n = 2), metastatic castration-sensitive PC ( = 4), and metastatic castration-resistant PC ( = 18). Study designs included RCTs ( = 7), non-RCTs ( = 2), and real-world studies ( = 15). Treatments used in included studies were abiraterone acetate plus prednisone (AAP; = 6), enzalutamide, lutetium-177 prostate-specific membrane antigen (Lu-PSMA; = 4 each), docetaxel ( = 3), apalutamide, radium-223 ( = 2 each), darolutamide, cabazitaxel, and pembrolizumab ( = 1 each). The evidence from RCTs (i.e., ARAMIS, SPARTAN, ARCHES, TITAN, LATITUDE, PREVAIL) demonstrated the clinical benefits of apalutamide, darolutamide, enzalutamide, and AAP in terms of overall, disease-free, and metastasis-free survival in Asian patients. These treatments were reported to be well tolerated, with no new safety signals identified in Asian population. The efficacy and safety profiles in Asian patients were consistent with the overall trial population. Data from real-world studies supported the effectiveness and tolerability of AAP, enzalutamide, radium-223, docetaxel, cabazitaxel, Lu-PSMA, and pembrolizumab in patients with advanced/metastatic PC.
CONCLUSIONS
This SLR of the Asian data on therapies for advanced PC from the pivotal and real-world studies confirms similar efficacy and safety outcomes, consistent with the results from the pivotal clinical trials. These findings will help clinicians make better treatment decisions in clinical practice for patients with advanced/metastatic PC.
