Abstract
OBJECTIVE In this retrospective pharmacovigilance study, we gathered data on drug-induced posterior reversible encephalopathy syndrome (PRES). Our goal was to identify the primary suspect drugs in PRES by analyzing the Food and Drug Administration Adverse Events Reporting System (FAERS) database. METHODS We identified and analyzed reports of PRES listed in the FAERS database between 2004 and 2021. Using the reporting odds ratio and 95% confidence interval, we evaluated the safety signals for each of the drugs associated with PRES. RESULTS We reviewed 11,077 reports of adverse events corresponding to PRES. The primary suspect drug categories were antineoplastics, immunosuppressants, and glucocorticoids. PRES was 24.77% more likely to occur in females than in males. Drug-induced PRES usually occurs in individuals with cancer, those who have undergone an organ/stem cell transplant, and those with autoimmune conditions. CONCLUSION Our results show that the drugs most commonly suspected to cause PRES were antineoplastics, immunosuppressants, and glucocorticoids. Future studies are needed to illuminate the pathophysiological alterations that underlie PRES. In the meantime, prescribers and patients should be made aware of the potential risks of PRES associated with pharmaceutical therapy, and the summaries of product characteristics for individual drugs should be updated to include this information.

Abstract
AIM Acute lymphoblastic leukaemia (ALL) therapy has been associated with a significant burden of toxicities. The aim of this study was to describe the full spectrum of toxic effects associated with childhood ALL. METHODS Toxicity-related data were collected from the Nordic Society of Paediatric Haematology and Oncology (NOPHO) ALL-2008 toxicity registry, in which data on 19 clinically relevant toxicities were registered during ALL treatment, and from patient medical records. All patients treated according to the NOPHO ALL-2008 protocol in Oulu University Hospital between 2008 and 2020 were included in the study. RESULTS The cohort consisted of 73 patients, 38 of whom were male. Mean age at diagnosis was 6.6 ± 4.2 (range 1.4-16.0) years. All but one of the patients developed at least one treatment-related toxicity and more than half had multiple toxicities. Female sex and older age were associated with a higher tendency towards toxicity. The most common toxicity was vincristine-induced peripheral neuropathy, which was observed in 70 patients. Most toxicities were moderate or severe, but even mild toxicities often affected leukaemia treatment. CONCLUSION Moderate and severe treatment-related toxicities are common, and most toxicities occur in a typical pattern in relation to the treatment phases.

Abstract
This study describes the profile of children diagnosed with posterior reversible encephalopathy syndrome (PRES) in the pediatric hematology oncology unit and highlights the clinical features of PRES in immunosuppressed children. This retrospective study included 10 children diagnosed with PRES with a mean age of 6.8 years. Acute lymphoblastic leukemia was the most common primary diagnosis followed by post-hematopoietic stem cell transplant patients. Most cases of PRES occurred within one month of treatment initiation. Hypertension was noted in all at the time of diagnosis. Neuroimaging revealed bilateral lesions with parietal and occipital lobe involvement being the most common. All patients received corticosteroids as part of treatment for primary diagnosis. Controlling blood pressure was critical in managing PRES. Consideration of PRES as a clinical possibility in pediatric hematology oncology unit in children presenting with symptoms such as headache, seizures, and visual disturbances will aid in early diagnosis after ruling out other causes of these symptoms.

Abstract
Background Posterior reversible encephalopathy syndrome (PRES) diagnosis relies on clinical and radiological characteristics. Clinical manifestations include focal neurologic deficits, hemiparesis, seizures with symptoms of intracranial hypertension, headache, nausea, vomiting, and visual field disturbances. The majority of patients have typical changes in magnetic resonance imaging. The epidemiology and outcomes of PRES in the pediatric cancer population have not been well described. Most of the available data are from retrospective analyses. Objective The aim of our study was to evaluate the clinical and radiological presentation as well as the outcome of PRES in children treated for cancers in a single center. Methods We analyzed data from 1,053 patients diagnosed with malignancies in a single center over 15 years to determine the incidence of PRES. Results 19/1053 (1.8%) patients developed PRES. The diagnosis was accompanied by a range of clinical symptoms including hypertension, seizures, altered mental status, and headaches. Magnetic resonance imaging was performed in all patients, and 14/19 (73.7%) exhibited typical findings consistent with PRES. Four patients (21.0%) required treatment in the Intensive Care Unit. Conclusion Posterior reversible encephalopathy syndrome (PRES) is a rare but significant complication in children with cancer.There is a clear need to establish clinical criteria for PRES to improve the diagnosis and treatment of patients with PRES, particularly in the pediatric oncological population.Further studies are needed to identify the risk factors for recurrent PRES, particularly in pediatric cancer patients undergoing chemotherapy or immunosuppressive treatment.

Abstract
OBJECTIVE To assess risk factors (RF) and severity grade of Posterior reversible encephalopathy syndrome (PRES) in children with hematological diseases. MATERIAL AND METHODS We analyzed cases of PRES in children during chemotherapy (CT) and after allogeneic hematopoietic stem cell transplantation (allo-HSCT). We estimated the following RF: arterial hypertension, steroid therapy, CT, immunosuppressive therapy (IST), infection and renal injury. RESULTS Thirty-five cases of PRES occurred in 32 patients (8 after allo-HSCT and 27 during CT) were included in this study. In the most of cases (94.3%), there were 2 and more RF. An increase in blood pressure level (88.6%), CT and IST (82.8%) administration, steroid therapy (71.4%) were the most significant for PRES development. Infectious process and the decline in renal function played a lesser role in this syndrome (31.4% and 14%). At the initial presentation of PRES, there were seizures (94.3%), a decrease of consciousness (28.6%), headache, vision disturbances and stomachache (20%). In the most of cases (91.4%), the 2nd and 3d grade according to the Common Terminology Criteria for Adverse Events (CTCAE 5.0) were observed. Brain magnetic resonance imaging (MRI) revealed the vasogenic edema of temporal (88.6%), occipital (74.3%), frontal (40%) lobes and the cerebellum (22.9%) more often than the cytotoxic edema (p=0.03). The cytotoxic edema was observed in the thalamus and the basal ganglia (2.9%) more often than in other parts of the brain (p<0.01). CONCLUSION The majority of PRES cases are caused by more than two RF. Arterial hypertension does not have a leading role among its causes. There is a significant correlation between the grade of PRES according to CTCAE 5.0 score and RF number (p<0.05).

Abstract
Vincristine (VCR) as a key drug for the treatment of acute lymphoblastic leukemia (ALL) is associated with neurotoxicity. We present a young man with a history of controlled childhood seizures who was diagnosed with pre-B-cell ALL and developed generalized tonic-clonic seizures following the Cancer and Leukemia Group B (CALGB) 8811 regimen. The patient also received oral itraconazole to prevent fungal infection initiated by chemotherapy. Possible causes of seizure, including electrolyte abnormalities, hypoglycemia, central nervous system infection or inflammation, were ruled out. According to the Naranjo Adverse Drug Reaction Scale, the patient's seizure had been attributed to VCR, possibly secondary to concomitant use of itraconazole and doxorubicin. The patient successfully recovered after discontinuation of VCR and supportive care. Clinicians should be aware of the possibility of vincristine-induced seizure in adult patients, especially with the concomitant use of drugs known to have potential drug-drug interactions.

Abstract
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is classically a reversible clinical radiographic syndrome associated with predominantly posterior leukoencephalopathy on neuroimaging. Magnetic resonance imaging (MRI) in adults demonstrates almost universally reversible parietal-occipital disease. We aimed to demonstrate in a cohort of children that "atypical" distribution is expected, acutely and on follow-up. METHODS A retrospective review of children diagnosed with PRES from 2010 to 2018 at our children's hospital was performed. All had MRI at diagnoses, with over half having follow-up MRIs. Images were reviewed by a neuroradiology-trained pediatric radiologist for confirmation of findings consistent with PRES/identification of involved regions. RESULTS Nineteen patients (aged zero to 18 years, 53% female) were included. Notably, two were infants. Nearly all had seizures; all had altered mental status and hypertension. Fifteen (84%) had MRI described as "atypical." Distribution of MRI findings was anatomically widespread, including nine with frontal findings. Twelve (63%) had follow-up imaging, of which approximately half remained abnormal. CONCLUSIONS Pediatric PRES MRI findings were more often atypical at time of diagnosis. Vasogenic edema related to the acute phases of PRES typically resolved; however, follow-up imaging identified new volume loss in the areas affected. Two of our subjects were younger than 13 months, younger than typically described. Our series demonstrates that imaging distribution in children with PRES does not mirror the classical posterior, reversible distribution described in adults and continues the recent trend of identifying PRES in infants.

Abstract
Due to high survival rates, long-term sequelae, especially neurotoxicity, need to be considered in childhood acute leukemias. In this retrospective analysis of morphologic changes of the brain in children treated for acute leukemias, we included 94 patients (77 ALL, 17 AML; 51 male, 43 female; median age: 5 years) from a single center. We analyzed 170 cranial MRI scans (T2, FLAIR axial) for morphologic alterations of the brain and variations of the ventricular width (GDAH). In addition, the corresponding literature was reviewed. More than 50% of all patients showed cerebral pathomorphologies (CP). They were seen more often in children with ALL (55.8%), ≤ 6 years of age (60.8%), in relapse (58.8%) or after CNS irradiation (75.0%) and included white matter changes, brain atrophy, sinus vein thrombosis and ischemic events. GDAH significantly enlarged mainly in children up to 6 years, with relapse, high-risk leukemias or ALL patients. However, GDAH can normalize again. The number of intrathecal Methotrexate applications (≤12 vs. >12) showed no correlation to morphologic alterations besides a significant increase in GDAH (−0.3 vs. 0.9 mm) between the first and last follow-up MRI in ALL patients receiving >12 ith. MTX applications. The role of ith. MTX on CP needs to be further investigated and correlated to the neurocognitive outcome of children with acute leukemias.

Abstract
BACKGROUND AND AIM Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological syndrome characterized by a neurotoxic state with vasogenic edema. We studied the clinical profile, predisposing factors, imaging features, and outcome of PRES in children receiving treatment for hematolymphoid malignancies. METHODS Retrospective analysis of the clinical data and radiological features of patients with PRES diagnosed between June 2014 and December 2019. RESULTS Fifty-two patients (boy: girl = 3:1) were diagnosed with PRES during the study period with a median age of 11 (range:1-15) years. Primary diagnoses were acute leukemias (n = 42), non-Hodgkin lymphoma (n = 8), Hodgkin lymphoma (n = 1), and Langerhan's cell histiocytosis (n = 1). Most common presenting symptoms were seizures (n = 52), altered sensorium (n = 42), headache (n = 39), and visual disturbances (n = 8). Hypertension at time of diagnosis was noted in 50 (96%) patients. Classic hyper-intense lesions on FLAIR and diffusion weighed (DW) images were noted in parieto-occipital region in 39 patients (75%). Central PRES involving basal ganglia was seen in 3 (6%) patients. A subsequent neuro-imaging was done in 18 patients (MRI: 13; CT: 5) at a median interval of 16.2 weeks. Neurological sequelae were observed in 10 (19%) patients, whereas 1 succumbed due to PRES. CONCLUSIONS PRES is an important clinico-radiological syndrome in patients undergoing chemotherapy for hematological malignancies. High index of suspicion, early diffusion-weighted images on MRI in children with classic symptoms help in early diagnosis. A small minority of patients may develop long-term sequelae.

Abstract
BACKGROUND To demonstrate and compare the clinical manifestations, laboratory findings, and neuroimaging findings of posterior reversible encephalopathy syndrome (PRES) in children with and without underlying renal disease. METHODS The study included 23 children with a diagnosis of PRES from January 2009 to March 2019. All data, including clinical manifestations, laboratory findings, underlying medical illness, and neuroimaging results, were obtained. RESULTS Sixteen had underlying renal disease. The median age of PRES onset was 10.3 years in children with renal disease and 9.8 years in children without renal disease. Higher blood pressure at the baseline, on admission, and at the onset of PRES was found in the renal disease group more than in the nonrenal disease group (P < 0.05). Seizures were likely seen in the renal disease group compared with the nonrenal disease group (P = 0.03). Generalized tonic-clonic seizures were the most common seizure type in both groups. An initial CT scan revealed vasogenic edema in 75% of the renal group and 85.7% of the nonrenal group. During a long-term follow-up, all children recovered without significant neurological deficits or subsequent epilepsy. CONCLUSIONS Hypertension and higher baseline blood pressure are more common in children with renal disease who develop PRES compared with nonrenal disease. Seizures are more common in the renal disease group. A computed tomographic (CT) scan can help with PRES diagnosis when magnetic resonance imaging is not available. All children with PRES recovered without significant neurological deficits or subsequent epilepsy.

Abstract
Acute leukemia (AL) is an important cause of morbidity and mortality in children, and neurological manifestations (NM) are frequent. The objective of this study was to analyze neurological manifestations in children with acute leukemia from cases attended in the last five years at the Centro Médico Nacional “20 de Noviembre”. Methods: Conducting a retrospective and analytical study from 1 January 2015 to 31 December 2020 in children with AL classified according to sex, age range and AL type. Participants were grouped according the presence of NM. Results: We analyzed 607 patients: 54.85% boys and 44.14% girls, with a mean age of 7.27 ± 4.54 years. When comparing groups, the NM group was significantly older (p = 0.01), and the highest prevalence was between 6 and 12 years old. ALL was predominant over the other lineages (p ≤ 0.01). The most frequent NM was CNS infiltration, seizures, headache and neuropathy. Death outcomes occurred in 18.7% of children with AML, 11.8% with ALL and 50% with MPAL (p ≤ 0.002). The NM group was associated with higher mortality during a follow-up time of 77.9 ± 49 months (44.4% vs. 8.9% deaths, NM vs. non-NM, respectively; OR = 3.3; 95% CI 2.4 to 4.6; p ≤ 0.0001). Conclusions: ALL was the most prevalent leukemia type. CNS infiltration, seizures, headache, neuropathy and PRES were the most frequent symptoms in the NM group. NM was associated with a higher mortality rate.

Abstract
Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) implicates enhanced intrathecal chemotherapy, which is related to CNS toxicity. Whether CNS involvement alone contributes to CNS toxicity remains unclear. We studied the occurrence of all CNS toxicities, seizures, and posterior reversible encephalopathy syndrome (PRES) in children with ALL without enhanced intrathecal chemotherapy with CNS involvement (n = 64) or without CNS involvement (n = 256) by flow cytometry. CNS involvement increased the risk for all CNS toxicities, seizures, and PRES in univariate analysis and, after adjusting for induction therapy, for seizures (hazard ratio [HR] = 3.33; 95% confidence interval [CI]: 1.26-8.82; p = 0.016) and PRES (HR = 4.85; 95% CI: 1.71-13.75; p = 0.003).

Abstract
Although more commonly seen in adult population, posterior reversible encephalopathy syndrome (PRES) can also be observed in pediatric patients. The etiopathogenesis of pediatric PRES is poorly understood, and the available evidence comes mostly from childhood cancer. Analysis of the sociodemographic and clinical characteristics of the different noncancer-related types can improve the understanding of pediatric PRES.

Abstract
Posterior reversible leukoencephalopathy syndrome (PRES) is a rare entity among children, characterised by acute neurological symptoms and radiological findings. The role of clinical symptoms and neuroimaging in predicting the prognosis of PRES have not been well-characterised. A retrospective descriptive study of children with PRES, admitted to a Paediatric Intensive Care Unit during a 10-year period, was performed to describe its characteristics, compare the accuracy of computed tomography (CT) scan and MRI on diagnosis and identify prognostic factors on paediatric population. Sixteen cases were identified. Most patients (13; 81%) presented underlying disorders, including malignancies (5; 31%), chronic kidney disease (3; 19%) and post-transplant status (3; 19%). Hypertension (15; 94%) was the most common trigger. All patients had seizures, 9 patients (56%) altered state of consciousness, 8 (50%) headache. CT scan was performed in 15 patients (94%) and MRI in 13 (81%); 1 patient underwent only MRI. MRI allows the identification of new areas of vasogenic oedema and a correct diagnosis of PRES when CT scan was inconclusive. Two patients (13%) remained with neurological sequelae and one died. In two patients (13%) cognitive disorders (specific learning disorder, intellectual disability, motor tic disorder) were diagnosed during follow-up period. Clinical presentation was not statistically associated with outcome. Also, atypical neuroimaging (haemorrhagic and unilateral lesions) were not statistically related with poor neurological or cognitive outcome. However, prospective studies with a larger cohort are needed to establish prognostic factors of PRES in the paediatric population.

Abstract
OBJECTIVES Drug resistant epilepsy has rarely been reported following posterior reversible encephalopathy syndrome (PRES), with few cases of mesial temporal sclerosis (MTS). The aim of this study was to report clinical and neuroimaging features of MTS subsequent to PRES in hemato-oncologic/stem cell transplanted children. MATERIALS AND METHODS Among 70 children treated in 2 pediatric hemato-oncologic Italian centers between 1994 and 2018 and presenting an episode of PRES, we retrospectively identified and analyzed a subgroup of patients who developed epilepsy and MTS. RESULTS Nine of 70 patients (12.8%) developed post-PRES persistent seizures with magnetic resonance imaging evidence of MTS. One patient died few months after MTS diagnosis, because of hematologic complications; the remaining 8 patients showed unprovoked seizures over time leading to the diagnosis of epilepsy, focal in all and drug resistant in 4. At PRES diagnosis, all patients with further evidence of epilepsy and MTS suffered of convulsive seizures, evolving into status epilepticus in 3. In 3 patients a borderline cognitive level or intellectual disability were diagnosed after the onset of epilepsy, and 2 had behavioral problems impacting their quality of life. CONCLUSIONS MTS and long-term focal epilepsy, along with potential cognitive and behavioral disorders, are not uncommon in older pediatric patients following PRES.

Abstract
OBJECTIVES Despite progress in the treatment of childhood acute lymphoblastic leukemia, severe complications are common, and the need of supportive care is high. We explored the cumulative prevalence, clinical risk factors, and outcomes of children with acute lymphoblastic leukemia, on first-line leukemia treatment in the ICUs in Sweden. DESIGN A nationwide prospective register and retrospective chart review study. SETTING Children with acute lymphoblastic leukemia were identified, and demographic and clinical data were obtained from the Swedish Childhood Cancer Registry. Data on intensive care were collected from the Swedish Intensive Care Registry. Data on patients with registered ICU admission in the Swedish Childhood Cancer Registry were supplemented through questionnaires to the pediatric oncology centers. PATIENTS All 637 children 0-17.9 years old with acute lymphoblastic leukemia diagnosed between June 2008 and December 2016 in Sweden were included. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Twenty-eight percent of the children (178/637) were admitted to an ICU at least once. The Swedish Intensive Care Registry data were available for 96% of admissions (241/252). An ICU admission was associated with poor overall survival (hazard ratio, 3.25; 95% CI, 1.97-5.36; p ≤ 0.0001). ICU admissions occurred often during early treatment; 48% (85/178) were admitted to the ICU before the end of the first month of acute lymphoblastic leukemia treatment (induction therapy). Children with T-cell acute lymphoblastic leukemia or CNS leukemia had a higher risk of being admitted to the ICU in multivariable analyses, both for early admissions before the end of induction therapy and for all admissions during the study period. CONCLUSIONS The need for intensive care in children with acute lymphoblastic leukemia, especially for children with T cell acute lymphoblastic leukemia and CNS leukemia, is high with most admissions occurring during early treatment.

Pharmacogenetics of the Central Nervous System-Toxicity and Relapse Affecting the CNS in Pediatric Acute Lymphoblastic Leukemia. Cancers (Basel) 2021; 13:cancers13102333.

Abstract
Simple Summary Despite recent improvements in cure rates, pediatric acute lymphoblastic leukemia (ALL) patients remain at risk to develop relapse disease or suffer from therapy-associated side effects. Over 5% of adverse events appear in the central nervous system (CNS) and can impact survival or quality of life of the patients. Inherited genetic variations are possible predictive factors for these adverse events. This retrospective study aimed to investigate if inherited genetic variations in genes encoding drug-metabolizing enzymes and drug transporters localized in the blood-brain barrier are predictive for CNS events. Our results suggest that certain ABCB1, ABCG2 and GSTP1 gene polymorphisms influence CNS toxicity and CNS relapse. A more effective drug-clearance could lead to less toxicity but contribute to a higher chance of relapse and vice versa. Genetic variants in ABCB1, ABCG2 or GSTP1 genes are promising candidates for personalized medicine. Abstract Despite improving cure rates in childhood acute lymphoblastic leukemia (ALL), therapeutic side effects and relapse are ongoing challenges. These can also affect the central nervous system (CNS). Our aim was to identify germline gene polymorphisms that influence the risk of CNS events. Sixty single nucleotide polymorphisms (SNPs) in 20 genes were genotyped in a Hungarian non-matched ALL cohort of 36 cases with chemotherapy related acute toxic encephalopathy (ATE) and 544 controls. Five significant SNPs were further analyzed in an extended Austrian-Czech-NOPHO cohort (n = 107 cases, n = 211 controls) but none of the associations could be validated. Overall populations including all nations’ matched cohorts for ATE (n = 426) with seizure subgroup (n = 133) and posterior reversible encephalopathy syndrome (PRES, n = 251) were analyzed, as well. We found that patients with ABCB1 rs1045642, rs1128503 or rs2032582 TT genotypes were more prone to have seizures but those with rs1045642 TT developed PRES less frequently. The same SNPs were also examined in relation to ALL relapse on a case-control matched cohort of 320 patients from all groups. Those with rs1128503 CC or rs2032582 GG genotypes showed higher incidence of CNS relapse. Our results suggest that blood-brain-barrier drug transporter gene-polymorphisms might have an inverse association with seizures and CNS relapse.

Abstract
The aim of the study was to analyze the characteristics of posterior reversible encephalopathy syndrome (PRES) cases treated at 10 different institutions in our country. Fifty-eight patients diagnosed with PRES were included in this study. The data of PRES cases from 10 departments of pediatric hematology/oncology were analyzed. The mean age of the patients at the time of diagnosis of PRES was 8.95±3.66 years. Most patients (80.4%) had a primary diagnosis of acute leukemia. Patients received chemotherapy (71.4%) and/or used steroids within 14 days before the diagnosis of PRES (85.7%). Hypertension was found in 83.9% of the patients. Twenty-six patients had infections and 22 of them had febrile neutropenia. The most common electrolyte disorders were hypocalcemia, hypomagnesemia, and hypopotassemia. Six patients had tumor lysis syndrome and 4 had inappropriate antidiuretic hormone syndrome. Magnetic resonance imaging was used for diagnosis in all patients. The most commonly involved regions by magnetic resonance imaging were occipital (58%), parietal (51%), and frontal lobes (45%), respectively. Twenty-five patients required intensive care and 7 patients were intubated. In conclusion, PRES may develop during the follow-up and treatment of hematological diseases. In addition to steroid and intense combined chemotherapies, immunosuppressive agents and hypertension are also factors that may be responsible for PRES.

Abstract
Simple Summary In this study, we investigated standardized post-chemotherapy magnetic resonance (MR) scans for leukoencephalopathy and patient- and treatment-related risk factors in childhood leukemia patients. As prevalence numbers are limited, our study provides the required estimations for this population. Furthermore, we demonstrate that younger patients might be more at-risk for development of leukoencephalopathy (LE), and that a higher intravenous methotrexate (IV-MTX) dose has a cumulative toxic effect, while the number of intrathecal administrations was not significantly associated with the extent of LE. This can suggest we should modify chemotherapeutic treatment regimens by decreasing the number of IV-MTX applications, with special attention for younger patients. Abstract Methotrexate (MTX) is associated with leukoencephalopathy (LE) in children treated for lymphoblastic leukemia/lymphoma (ALL/LBL). However, large-scale studies with systematic MR acquisition and quantitative volumetric lesion information remain limited. Hence, the prevalence of lesion burdens and the potential risk factors of LE in this population are still inconclusive. FLAIR-MRI scans were acquired at the end of treatment in children who were treated for ALL/LBL, which were quantitatively analyzed for LE. Voxels were assigned to the lesion segmentation if indicated by two raters. Logistic and linear regression models were used to test whether lesion presence and size were predicted by risk factors such as age at diagnosis, gender, intrathecal (IT-) or intravenous (IV-)MTX dose, CNS invasion, and acute neurological events. Patients with a pre-existing neurological condition or low-quality MR scan were excluded from the analyses. Of the 129 patients, ten (8%) suffered from CNS invasion. Chemotherapy-associated neurological events were observed in 13 patients (10%) during therapy, and 68 patients (53%) showed LE post-treatment. LE was more frequent in cases of lower age and higher cumulative IV-MTX doses, while the extent of LE and neurological symptoms were associated only with IV-MTX doses. Neurological events were not significantly associated with LE, even though symptomatic patients demonstrated a higher ratio of LE (n = 9/13) than asymptomatic patients (n = 59/116). This study suggests leukoencephalopathy frequently occurs in both symptomatic and asymptomatic leukemia patients. Younger children and patients treated with higher cumulative IV-MTX doses might need more regular screening for early detection and follow-up of associated sequelae.

Abstract
AbstractThe aim of this study was to investigate the association of neuroimaging, clinical, and laboratory findings in children with different underlying diseases who developed posterior reversible encephalopathy syndrome (PRES). All consecutive pediatric patients referred to our institute between 2000 and 2017 were retrospectively evaluated for newly diagnosed PRES. Clinical data, medical history, and therapies administered at the time of PRES and laboratory findings were reviewed as the magnetic resonance imaging (MRI) obtained at PRES presentation and during follow-up. Statistics included Mann–Whitney U, Chi-square, and Fisher's exact tests. A total of 39 pediatric patients (25 males, median age = 8.8 years) with a confirmed diagnosis of PRES were included. The patients were divided into four groups based on the underlying disease: (1) patients with hemato-oncological diseases not transplanted (n = 15, 38.5%), (2) who underwent hematopoietic stem cell transplantation (HSCT; n = 12, 30.8%), (3) affected by renal (n = 8, 20.5%), and (4) by autoimmune diseases (n = 4, 10.2%). Hemato-oncological patients and those undergoing HSCT presented a higher incidence of involvement of deep gray matter structures and hemorrhagic lesions when compared with patients with renal and autoimmune disorders (p = 0.036 and p = 0.036, respectively). No differences emerged among different groups of patients regarding presenting PRES symptoms, arterial blood pressure, laboratory findings, and extent of MRI abnormalities and these parameters did not show association with outcome.In conclusion, in pediatric patients with different diseases who develop PRES, involvement of deep gray matter structures and hemorrhagic lesions are more common in hemato-oncological patients and those undergoing HSCT. Clinical and radiologic outcome is favorable independently of clinical data and extent of MRI abnormalities.

Posterior reversible encephalopathy syndrome after induced hypertension therapy for delayed cerebral ischemia after subarachnoid hemorrhage: A case-control study. J Neurol Sci 2021; 421:117313. [PMID: 33461062 DOI: 10.1016/j.jns.2021.117313] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 01/01/2021] [Accepted: 01/05/2021] [Indexed: 12/19/2022]
Abstract
BACKGROUND Posterior reversible encephalopathy syndrome (PRES) is associated with arterial hypertension. Our aim was to investigate whether induced hypertension (IH) as therapy for delayed cerebral ischemia (DCI) after subarachnoid hemorrhage (SAH) is associated with PRES and to identify risk factors for PRES. MATERIAL AND METHODS We retrospectively searched our database for patients with SAH and IH in our institution between 2009 and 2018 and identified additional cases of PRES after SAH with IH from the literature. We then analyzed demographic findings and clinical features of these patients. RESULTS 172 patients with acute SAH received IH. PRES was diagnosed in 3/172 (1.7%) patients. Our literature search revealed 17 additional cases. The pooled PRES group (n = 20) was non-significantly older than the non-PRES group (n = 169) (median, 62.5 years vs. 52 years, p = 0.06). No significant differences were found between both groups with regard to sex (p = 0.73), Hunt & Hess-Score (p = 0.9), aneurysm treatment (p = 0.13), and time from diagnosis of SAH to the start of IH (p = 0.14). CONCLUSIONS PRES after IH in SAH patients occurred in 1.7% of our patients. Our results imply that it is important to be aware of a possible development of a PRES in older SAH patients with IH, irrespective of sex, initial clinical status, and treatment modality.

Abstract
This study investigated the management and clinical outcomes along with associated factors of posterior reversible encephalopathy syndrome (PRES) in childhood hematologic/oncologic diseases. We present data from children with hematologic/oncologic diseases who developed PRES after treatment of the primary disease with chemotherapy and hematopoietic stem cell transplantation (HSCT) at 3 medical centers in Changsha, China from 2015 to 2020, and review all previously reported cases with the aim of determining whether this neurologic manifestation affects the disease prognosis. In the clinical cohort of 58 PRES patients, hypertension [pooled odds ratio (OR) = 4.941, 95% confidence interval (CI): 1.390, 17.570; P = 0.001] and blood transfusion (OR = 14.259, 95% CI: 3.273, 62.131; P = 0.001) were significantly associated with PRES. Elevated platelet (OR = 0.988, 95% CI: 0.982, 0.995; P < 0.001), hemoglobin (OR = 0.924, 95% CI: 0.890, 0.995; P < 0.001), and blood sodium (OR = 0.905, 95% CI: 0.860, 0.953; P < 0.001), potassium (OR = 0.599, 95% CI: 0.360, 0.995; P = 0.048), and magnesium (OR = 0.093, 95% CI: 0.016, 0.539; P = 0.008) were protective factors against PRES. Data for 440 pediatric PRES patients with hematologic/oncologic diseases in 21 articles retrieved from PubMed, Web of Science, and Embase databases and the 20 PRES patients from our study were analyzed. The median age at presentation was 7.9 years. The most common primary diagnosis was leukemia (62.3%), followed by solid tumor (7.7%) and lymphoma (7.5%). Most patients (65.0%) received chemotherapy, including non-induction (55.2%) and induction (44.8%) regimens; and 86.5% used corticosteroids before the onset of PRES. Although 21.0% of patients died during follow-up, in most cases (93.2%) this was not attributable to PRES but to severe infection (27.3%), underlying disease (26.1%), graft-vs.-host disease (14.8%), multiple organ dysfunction syndrome (8.0%), and respiratory failure (3.4%). PRES was more common with HSCT compared to chemotherapy and had a nearly 2 times higher mortality rate in patients with oncologic/hematologic diseases than in those with other types of disease. Monitoring neurologic signs and symptoms in the former group is therefore critical for ensuring good clinical outcomes following treatment of the primary malignancy.

Abstract
Objective: Chemotherapy and hematopoietic stem cell transplantation (HSCT) play important roles in clinical etiology, symptoms, signs, imaging findings, and biochemical parameters for inducing posterior reversible encephalopathy syndrome (PRES) in pediatric oncologic diseases. We aimed to evaluate various risk factors of pediatric oncologic diseases after conducting chemotherapy and HSCT to induce PRES for predicting the clinical prognosis frequency. Methods: The literature was performed on PubMed, Web of Science, and Embase databases to recognize the qualified studies. The odds ratios (ORs) of related risk factors and their corresponding 95% confidence intervals (CIs) were used to compute the pooled assessments of the outcomes. Results: Six studies were included in the meta-analysis, involving 828 records. The risk of female children has a significantly higher incidence than male children in oncologic age groups of PRES. Children over the age of 10 years old in oncologic age groups develop a significantly increased risk of PRES. Acute graft-versus-host disease (GVHD) has a significant promotion effect on the occurrence of PRES. Hypertension can promote the occurrence of PRES in children. The risk of PRES in immunodeficient children increases significantly. Children with sickle cell disease (SCD) have a significantly increased risk of PRES. The risk of PRES in children with T-cell leukemia rises considerably. The central nervous system (CNS) leukemia/involvement has a significant role in promoting the occurrence of PRES in children. The pooled OR for the factors male, ≥ 10 years old of age, acute GVHD, hypertension, immunodeficiency, SCD, T-cell leukemia, CNS leukemia/involvement was 0.66 (95% CI: 0.58, 0.76; P < 0.00001), 2.06 (95% CI: 1.23, 3.43; P < 0.006), 1.32 (95% CI: 1.14, 1.53; P < 0.0003), 8.84 (95% CI: 7.57, 10.32; P < 0.00001), 2.72 (95% CI: 1.81, 4.08; P < 0.00001), 2.87 (95% CI: 2.15, 3.83; P < 0.00001), 2.84 (95% CI: 1.65, 4.88; P < 0.0002), and 3.13 (95% CI: 1.43, 6.84; P < 0.004), respectively. Conclusions: The result of this meta-analysis suggests that female children, age over 10 years old, acute GVHD, hypertension, immunodeficiency, SCD, T-cell leukemia, and CNS leukemia/involvement are likely to have the poor outcome in pediatric oncologic/hematologic diseases in PRES.

Abstract
AbstractThe posterior reversible encephalopathy syndrome was characterized by Hinchey and colleagues in the 1990s. The condition frequently afflicts patients suffering from hematologic and solid organ malignancy and individuals undergoing transplantation. Cases are more frequently described in the adult population compared with children. In the pediatric population, malignancy, transplantation, renal disease, and hypertension represent the most common etiologies. Theories on pathogenesis have centered upon cerebrovascular dysautoregulation with increases in blood–brain barrier permeability. This generates vasogenic edema of the cerebral parenchyma and consequent neurologic deficits. The parietal and occipital lobes are affected with greatest prevalence, though frontal and temporal lobe involvement is frequent, and that of the contents of the infratentorial posterior cranial fossa are occasionally described. The clinical presentation involves a characteristic constellation of neurologic signs and symptoms, most typically inclusive of headache, visual-field disturbances, abnormalities of visual acuity, and seizures. Supportive care, withdrawal of the offending agent, antihypertensive therapy, and prophylactic anticonvulsants affect convalescence in majority of cases. The principal challenge lies in identifying the responsible agent precipitating the condition in patients with malignancy and those having undergone transplantation and thus deciding which medication among a multidrug treatment regimen to withhold, the duration of drug cessation required to effect clinical resolution, and the safety of resuming treatment with the compound. We accordingly reviewed and evaluated the literature discussing the posterior reversible encephalopathy syndrome in children.

Abstract
BACKGROUND Children with central nervous system (CNS) toxicity during therapy for acute lymphoblastic leukaemia (ALL) are at risk for treatment modifications, long-term sequelae and even higher mortality. A better understanding of CNS symptoms and their complications improves the potential to prevent and treat them. METHODS Patient files from 649 children treated with Nordic Society of Pediatric Hematology and Oncology ALL92 and ALL2000 protocols in Finland were reviewed retrospectively for any acute CNS symptom. Detailed data on symptoms, examinations and treatment of the underlying CNS complications were collected from the medical records. Disease-related and outcome data were retrieved from the Nordic leukaemia registry. RESULTS Altogether, 13% (86) of patients with ALL had acute CNS symptoms. Most symptoms (64%) occurred during the first 2 months of therapy. Posterior reversible encephalopathy syndrome was the most frequent complication (4.5%). Cerebrovascular events were diagnosed in 10 cases (1.6%), while methotrexate-related stroke-like syndrome (SLS) was observed in only one patient (0.2%). CNS symptoms due to systemic or unclear conditions, especially sepsis, were important for differential diagnosis. CNS leukaemia was associated with CNS symptoms (hazard ratio [HR] = 4.03; P = .003), and epilepsy was a common sequel of CNS complications (19%). CONCLUSIONS Acute CNS symptoms are common during ALL therapy, occurring mainly during the first 2 months of treatment. Patients with CNS leukaemia at diagnosis are at a higher risk for CNS toxicity. Despite intensive CNS-directed methotrexate treatment, SLS was diagnosed extremely rarely in our series.

Abstract
AIM To evaluate clinical and radiologic presentation, and neurologic outcome of pediatric posterior reversible encephalopathy syndrome (PRES). PATIENTS AND METHODS The study included 24 children (14 males and 10 females) diagnosed with PRES who were prospectively followed for 2 years. They were evaluated using Wechsler Intelligence Scale, electroencephalograph (EEG), and brain magnetic resonance imaging (MRI). RESULTS The mean age of the studied patients at the time of diagnosis of PRES was 6 years (±2.2). Chemotherapy for cancer represented 66.7% of the causes of PRES in the studied children, followed by renal disorders and immunosuppressive agents for hematopoietic stem cell transplantation. Twenty-seven attacks of PRES were reported as 3 children developed a second attack of PRES. Normal intelligence quotient was found in 95.8% of studied children after PRES. Residual abnormalities in follow-up MRI were demonstrated in 3 children. Epilepsy and residual MRI lesions were reported in 2 of the 3 children with recurrent PRES. Residual lesions in follow-up MRI and epilepsy were more significantly reported after recurrent PRES (P < .05). CONCLUSIONS Neoplastic, renal disorders and hematopoietic stem cell transplantation represent the main disorders associated with PRES in children. Chemotherapeutic drugs, immunosuppressants, and hypertension are the main risk factors for pediatric PRES. The outcome of pediatric PRES is good, but long-term neurologic sequelae can occur, mainly epilepsy and residual MRI abnormalities. Recurrence of PRES is infrequently reported in children receiving chemotherapeutic or immunosuppressive drugs. Recurrent PRES is a risk factor for long-term neurologic sequelae.

Abstract
Posterior reversible encephalopathy syndrome (PRES) is well-described in adults, but has been reported with relative rarity in children, usually occurring in the context of chemotherapy for acute leukemia. Pathogenesis involves perturbed cerebral autoregulation leading to vasogenic edema predominantly affecting the parieto-occipital white matter, though involvement of the frontal and temporal lobes, as well as posterior fossa, is also described. We review the literature on the pathophysiology, diagnosis, and management of PRES in pediatric patients.

Prognostic factors and seizure outcome in posterior reversible encephalopathy syndrome (PRES) in children with hematological malignancies and bone marrow failure: A retrospective monocentric study. Seizure 2019; 72:1-10.

Abstract
PURPOSE The aim of this study was to evaluate seizure outcome in children with hematological malignancies and PRES and to identify prognostic factors that could help manage the syndrome. METHOD We retrospectively reviewed the report data of 21 patients diagnosed with hematological malignancy or aplastic anemia and PRES between 2008 and 2018. Basic demographic data, oncology treatment, presymptomatic hypertension before PRES manifestation, neurological status, seizure type, and EEG and MRI findings at PRES onset and at the one-year follow-up visit were studied. Patients who developed remote symptomatic seizures or epilepsy were identified. RESULTS We included 21 children (11 females and 10 males) in the study. Sixteen patients (76.2%) were diagnosed with ALL and the rest individually with AML, CML, T-lymphoma, Burkitt lymphoma, and severe aplastic anemia. Presymptomatic hypertension (PSH) was evaluated in 19 patients and was present in 18 (94.7%). The duration was 9 h and more in 16 patients (88.8%); the severity was grade II in 12 patients (66.7%). Seizures as the initial symptom of PRES were present in 17 patients (80.9%). Four patients (19.0%) were assessed with remote symptomatic seizures. Two of them (9.5%) had ongoing seizures at the one-year follow-up visit and were diagnosed with epilepsy. The presence of gliosis on follow-up MRI indicated worse outcome with development of epilepsy (without statistical significance). CONCLUSIONS PRES syndrome has an overall good prognosis and the evolution to epilepsy is rare. The severity and duration of PSH or seizure severity and EEG findings at PRES onsetwere not associated with worse neurological outcomes in this study.
