Comparative Study Meta-Analysis
Comparison of early mortality between leukapheresis and non-leukapheresis in adult acute myeloid leukemia patients with hyperleukocytosis: a systematic review and meta-analysis.
OBJECTIVES
One of the treatment modalities that can be used for hyperleukocytosis is leukapheresis. However, the result of studies showing the benefit of early mortality through the use of leukapheresis versus no leukapheresis is still inconclusive. Hence, we aimed to conduct a systematic review with meta-analysis to determine the effect of leukapheresis on early mortality in AML patients with hyperleukocytosis.
METHODS
We conducted a literature search on five databases (PubMed, EBSCOhost, Scopus, Clinicalkey, and JSTOR) up to October 2021 for studies comparing early mortality outcomes between hyperleukocytosis AML patients treated with leukapheresis versus no leukapheresis. Summary odds ratios (OR) and 95% confidence intervals (CI) were calculated using random-effects models. Heterogeneity tests were presented in I value and publication bias was analyzed using a funnel plot.
RESULTS
Eleven retrospective cohort studies were eligible based on the inclusion and exclusion criteria. Pooled analysis showed that there was no significant difference in early mortality between patients receiving leukapheresis and not receiving leukapheresis in studies using hyperleukocytosis cutoff of 95,000/mm or 100,000/mm (OR: 1.17; 95% CI: 0.74-1.86; : 0.50; I: 0%). Similarly, studies using hyperleukocytosis cutoff of 50,000/mm also showed no benefits of early mortality (OR: 0.67; 95% CI: 0.43-1.05; : 0.08; I: 0%). Most of the studies used had a moderate risk of bias due to being observational studies. Funnel plot showed an indication of publication bias on studies using hyperleukocytosis cutoff of ≥50,000/mm.
CONCLUSION
The use of leukapheresis does not provide early mortality benefit in adult AML patients with hyperleukocytosis.

General Hospital Psychiatry 2022To ascertain the clinical characteristics of anti-NMDA receptor encephalitis (NMDARE) in older patients. (Review)
Review
OBJECTIVE
To ascertain the clinical characteristics of anti-NMDA receptor encephalitis (NMDARE) in older patients.
METHOD
A systematic literature review using PubMed and Scopus of all published case reports of NMDARE was undertaken, from database inception to June 2020. From this, cases reporting on patients older than 65 years of age and whose diagnosis was confirmed by the presence of anti-NMDAR antibodies in CSF were selected.
RESULTS
23 case reports fulfilling the study's criteria were found. Median age was 70.1 years (range 65-84), fourteen were female (60.9%), and mostly presented with acute behavioral and cognitive changes (95.7%). Atypical psychosis occurred in eleven patients (47.8%) with a sudden onset and fluctuating clinical pattern of delusions (39.1%), hallucinations (30.4%), and motility disturbances (34.8%) including catatonia (17.4%). Nine patients presented with seizures (39.1%). Pleocytosis in CSF (>5 WBC) was described in twelve cases (52.2%). Eleven cases (47.8%) had abnormal brain magnetic resonance imaging (MRI) scans with limbic inflammatory lesions. Thirteen patients had an abnormal EEG (56.5%).
CONCLUSION
NMDARE should be included in the differential diagnosis of older patients who present with new psychiatric episodes, especially when characterized by sudden onset psychotic polymorphic symptomatology, fluctuating course with marked cognitive decline, and with catatonic features.

This study aimed to identify potential risk factors for severe hand-foot-mouth disease (HFMD). The PubMed, Embase, the Cochrane Library, Sinomed, WanFang, CNKI, and VIP databases were searched (up to August 2021). Twenty-nine studies (9,241 and 927,355 patients with severe HFMD and controls, respectively; all from China) were included. EV71 was associated with higher odds of severe HFMD compared with other agents (OR = 4.44, 95%CI: 3.12-6.33, < 0.001). Being home-raised (OR = 1.99, 95%CI: 1.59-2.50, < 0.001), higher number of children in the family (OR = 2.09, 95%CI: 1.93-2.27, < 0.001), poor hand hygiene (OR = 2.74, 95%CI: 1.78-4.23, < 0.001), and no breastfeeding (OR = 2.01, 95%CI: 1.45-2.79, < 0.001) were risk factors for severe HFMD. First consulting to a district-level or above hospital (OR = 0.34, 95%CI: 0.25-0.45, < 0.001) and diagnosis of HFMD at baseline (OR = 0.17, 95%CI: 0.13-0.24, < 0.001) were protective factors against severe HFMD. Fever, long fever duration, vomiting, lethargy, leukocytosis, tic, and convulsions were each associated with severe HFMD (all < 0.05), while rash was not. EV71, lifestyle habits, frequent hospital visits, and symptoms are risk factors for severe HFMD in children in China, while early diagnosis and admission to higher-level hospitals are protective factors.

Review
The impact of SARS-CoV-2 infection on heart transplant recipients is unknown. Literature is limited to case reports and series. The purpose of this study is to identify the clinical features, outcomes, and immunosuppression strategies of heart transplant recipients with COVID-19 infection. A systematic review was conducted using the search term "Coronavirus" or COVID," "SARS-CoV-2," "cardiac transplantation," and "heart transplant." Case reports and retrospective studies were gathered by searching Medline/PubMed, Google Scholar, CINAHL, Cochrane CENTRAL, and Web of Science. Thirty-three articles were selected for review. We identified 74 cases of SARS-CoV-2 infection in heart transplant and heart-kidney transplant recipients. The mean age was 60.5 ± 15.8 years, and 82.4% were males with median time from transplant of 6.5 years. Commonest symptoms were fever, cough, and dyspnea, but new left ventricular (LV) dysfunction was rare. Leukocytosis, lymphopenia, elevated inflammatory markers, and bilateral ground-glass opacities were common. Mortality was high, with particularly poor survival in patients who required intensive care unit (ICU) admission and older patients. Immunosuppression involved discontinuation of antimetabolites and steroids. COVID-19 infection in heart transplant (HT) recipients presents similarly to the general population, but new onset of LV dysfunction is uncommon. Immunosuppression strategies include increase in corticosteroids and discontinuation of antimetabolites.

Review
BACKGROUND
Several reports have associated the severe Coronavirus disease-2019 (sCOVID-19) with secondary-hemophagocytic lymphohistiocytosis (sHLH) and proposed utilizing the hemophagocytic syndrome diagnostic score (HScore) for sCOVID-19 patients. We conducted a systematic review and meta-analysis to find the possible association of HScore parameters with severity in COVID-19 patients.
METHODS
A systematic search was performed in Medline via PubMed, EMBASE, and Cochrane databases using all HScore and COVID-19 keywords. The studies were all from 2020, and the study language was limited to English. The records were screened based on inclusion/exclusion criteria. Random/fixed-effect models were employed for meta-analysis, based on the I index of parameters. The pooled mean differences were estimated for continuous parameters. The pooled odds-ratio was estimated for fever. The level of significance was set at 0.05.
RESULTS
Eighteen studies (comprising 2459 patients) out of 26151 screened studies were included in this meta-analysis. The results showed that the level of leukocyte, neutrophil, aspartate transaminase (AST), ferritin, and fibrinogen were significantly higher in sCOVID-19 patients than in non-severe ones. Significant lower levels of lymphocyte, platelet, and hemoglobin were also found in sCOVID-19 patients than non-severe patients. Fever was nearly associated with two times increased odds of sCOVID-19 (P=0.051).
CONCLUSION
Lymphopenia, thrombocytopenia, hypohemoglobinemia, hyperferritinemia, high levels of AST, and fever are common features of both sCOVID-19 and HLH. However, the leukocytosis, neutrophilia, and hyperfibrinogenemia found in sCOVID-19 are in contrast with HScore. Conclusively, HScore parameters could be risk factors for sCOVID-19. However, some parameters' roles are contradictory, suggesting the need for further investigation and a new way of HScore interpretation in sCOVID-19 patients.A preprint of this study was published at https://www.researchsquare.com/article/rs-54490/v2.

Growing evidence demonstrates the association of encephalitis, meningoencephalitis or encephalomyelitis, with SARS-CoV-2 infection. This study aims to determine the profile and possible mechanisms behind CNS inflammatory diseases in the context of Covid-19. We conducted a systematic review of case reports on Covid-19-related encephalitis, meningoencephalitis, acute necrotizing encephalitis, and acute disseminated encephalomyelitis in adults, published before January 2021. A total of 182 cases (encephalitis = 109, meningoencephalitis = 26, acute disseminated encephalomyelitis = 35, acute necrotizing (hemorrhagic) encephalitis = 12) were included. While cerebrospinal fluid (CSF) pleocytosis and increased protein level was present in less than 50%, magnetic resonance imaging (MRI) and electroencephalogram (EEG) were abnormal in 78 and 93.2% of all cases, respectively. Viral particles were detected in cerebrospinal fluid of only 13 patients and autoantibodies were present in seven patients. All patients presented with altered mental status, either in the form of impaired consciousness or psychological/cognitive decline. Seizure, cranial nerve signs, motor, and reflex abnormalities were among associated symptoms. Covid-19-associated encephalitis presents with a distinctive profile requiring thorough diagnosis and thereby a comprehensive knowledge of the disease. The clinical profile of brain inflammation in Covid-19 exhibits majority of abnormal imaging and electroencephalography findings with mild/moderate pleocytosis or proteinorrhachia as prevalent as normal cerebrospinal fluid (CSF). Oligoclonal bands and autoantibody assessments are useful in further evaluating neuro-covid patients, as supported by our pooled evidence. Despite the possibility that direct viral invasion cannot be easily estimated, it is still more likely that immune-mediated or autoimmune reactions play a more important role in SARS-CoV-2 neuroinflammation.

Review
BACKGROUND AND OBJECTIVES
Clozapine is the only antipsychotic approved for treatment-resistant schizophrenia. Despite its superior efficacy profile as compared with other antipsychotics, clozapine remains underutilized. Clozapine monitoring systems clearly describe the proposed management of clozapine-induced neutropenia; however, no specific mention is made of how to interpret neutrophilic leukocytosis, despite that being a relatively frequent finding. Prescribers unfamiliar with this molecule may misjudge its clinical significance, potentially leading to untimely treatment interruption. Here, we systematically review the literature on the risk of neutrophilic leukocytosis during clozapine treatment, and describe eight additional cases among our patient cohort.
MATERIALS AND METHODS
We performed a systematic review of the literature on PubMed and Embase using the PRISMA 2020 guidelines, and selected all original reports describing either (1) the prevalence of neutrophilic leukocytosis during clozapine treatment, or (2) the clinical significance of neutrophilic leukocytosis. We described eight additional cases of neutrophilic leukocytosis during clozapine treatment while attending an outpatient psychiatric clinic.
RESULTS
Our research ultimately yielded the selection of 13 articles included in this systematic review. The case series highlighted the presence of stable and clinically unremarkable neutrophilia during a follow-up ranging from one to ten years.
CONCLUSIONS
Existing evidence indicates that leukocytosis associated with clozapine treatment can be considered as an asymptomatic and benign condition, suggesting that no change in clozapine treatment is needed upon its detection.

Meta-Analysis Review
AIM
To meta-analytically examine the frequency and prognostic impact of preoperative leukocytosis in endometrial carcinoma (EC).
METHODS
Five major databases were searched till 01-February-2021. Studies that evaluated the frequency of preoperative leukocytosis or its correlation with pathological and survival outcomes in EC patients were included. Data were pooled as mean differences (MD), odds ratios (OR), or hazard ratios (HR) with 95% confidence intervals.
RESULTS
Nine retrospective studies, with low risk of bias, were included. The pooled prevalence of preoperative leukocytosis was 11.2% (95% CI: 8.2-14.3). There was a significant correlation between preoperative leukocytosis and FIGO stage III-IV (OR = 2.10, 95% CI: 1.60-2.75), ≥50% myometrial invasion (OR = 1.32, 95% CI: 1.02-1.72), lymph node involvement (OR = 1.83, 95% CI: 1.29-2.59), cervical involvement (OR = 2.29, 95% CI: 1.68-3.13), adnexal involvement (OR = 2.17, 95% CI: 1.42-3.31), and tumor size (MD = 1.10 cm, 95% CI: 0.63-1.58). However, preoperative leukocytosis did not significantly correlate with tumor grade II-III, non-endometrioid histology, peritoneal cytology, and lympho-vascular space involvement (p > 0.05). Additionally, preoperative leukocytosis correlated with higher rates of death (OR = 2.85, 95% CI: 2.03-4.00), tumor recurrence (OR = 2.36, 95% CI: 1.21-4.61), and worse overall survival at univariate and multivariate analyses (HR = 2.90, 95% CI: 2.24-3.75 and HR = 2.16, 95% CI: 1.59-2.94, respectively). As for disease-free survival, preoperative leukocytosis emerged as an independent prognostic factor on univariate (HR = 1.27, 95% CI: 1.16-1.39) but not multivariate (HR = 1.08, 95% CI: 1.00-1.18) analyses.
CONCLUSIONS
Preoperative leukocytosis is common and correlates with poor pathological and survival outcomes in EC patients.

Comparative Study Meta-Analysis
Tacrolimus versus cyclophosphamide for patients with idiopathic membranous nephropathy and treated with steroids: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
The therapeutic effects of tacrolimus (TAC) versus cyclophosphamide (CTX) were not fully illustrated for patients with idiopathic membranous nephropathy (IMN).
METHODS
The PubMed, EmBase, Cochrane library, and CNKI were systematically searched throughout March 2020 for randomized controlled trials evaluating the therapeutic effects of TAC versus CTX for IMN patients treated with steroids. The pooled relative risks (RRs) and weighted mean differences (WMDs) with 95% confidence intervals (CIs) were calculated using the random-effects model.
RESULTS
Twelve trials recruited a total of 868 IMN patients were identified and contained in final meta-analysis. Patients in TAC group was associated with an increased incidence of overall remission (12 trials: 868 patients; RR: 1.21; 95% CI: 1.11-1.31; < 0.001) and complete remission (12 trials: 868 patients; RR: 1.50; 95% CI: 1.25-1.80; < 0.001). Moreover, we noted TAC therapy significantly reduced urinary protein excretion (9 trials: 567 patients; WMD: -1.06; 95%CI: -1.41 to -0.71; < 0.001), and increased serum albumin (9 trials: 567 patients; WMD: 5.37; 95%CI: 2.97 to 7.77; < 0.001) than CTX therapy. Furthermore, no significant difference between TAC and CTX for serum creatinine was detected (6 trials: 378 patients; WMD: 0.15; 95%CI: -3.46 to 3.75; = 0.936). Finally, the risk of alopecia ( = 0.008), infection ( = 0.045), leukocytosis ( = 0.002), and elevated ALT/AST ( = 0.011) in TAC group was significantly lower than CTX group, whereas TAC was associated with an increased risk of tremor than CTX ( = 0.010).
CONCLUSIONS
This study found IMN patients treated with TAC combined with steroids provides a better therapeutic effect and less adverse events than those treated with CTX combined with steroids, with moderate-certainty evidence.

Cardiovascular Implantable Electronic Device Infection and New Insights About Correlation Between Pro-inflammatory Markers and Heart Failure: A Systematic Literature Review and Meta-Analysis.
Surgical approaches to treat patients with abnormal pro-inflammatory parameters remain controversial, and the debate on the correlation between hematological parameter alteration in cardiac implantable electronic device (CIED) infection and the increase in mortality continues. We performed a systematic review using the PubMed, Scopus, and Cochrane Library databases. Twenty-two articles from May 2007 to April 2020 were selected and divided according to the following topics: prevalence of microbes in patients with CIED infection; characteristics of patients with CIED infection; comparison between patients who underwent and did not undergo replantation after device extraction; and correlation between alteration of hematological parameters and poor prognosis analysis. Epidemiological analysis confirmed high prevalence of male sex, staphylococcal infection, and coagulase-negative staphylococci (CoNS). The most common comorbidity was heart failure. Complete removal of CIED and antimicrobial therapy combination are the gold standard. CIED replacement was associated with higher survival. High preoperative white blood cell count and C-reactive protein levels increased the risk of right ventricular failure (RVF) development. Increased red blood cell distribution width (RDW) value or decreased platelet count was correlated with poor prognosis. No correlation was noted between preoperative leukocytosis and CIED infection. A relevant correlation between leukocytosis and RVF was observed. Heart failure may be related to high RDW values and decreased platelet count. Data on the correlation between hematological parameter alteration and poor prognosis are missing in many studies because of delayed implantation in patients showing signs of infection.
