Abstract
The St Jude Total Therapy Study XV was the first clinical trial to prospectively use minimal residual disease levels during and after remission induction therapy to guide risk-directed treatment. We used the Total Therapy XV protocol with minimal modification in treating 115 newly diagnosed pediatric acute lymphoblastic leukemia patients from low- and middle-income groups from January 2011 to December 2017. The mean age at diagnosis was 5.97 ± 3.96 years. The median follow-up period was 88 months. Three (2.6%) patients had bone marrow relapse, and one (0.87%) had an isolated central nervous system relapse. Nineteen of the patients (16.52%) died due to infection-related complications, three (2.61%) died due to progressive disease, and one (0.87%) died due to hematopoietic stem cell transplant complications. Five-year overall survival was 80%, and event-free survival was 78.3%. Our results showed that the Total XV treatment protocol could be used successfully in patients with ALL from low- and middle-income populations. However, infection-related deaths remain a significant problem.

Risk factors for steroid-induced adverse psychological reactions and sleep problems in pediatric acute lymphoblastic leukemia: A systematic review. Psychooncology 2021; 30:1009-1028.

Abstract
OBJECTIVE Steroids play an essential role in treating pediatric acute lymphoblastic leukemia (ALL). The downside is that these drugs can cause severe side effects, such as adverse psychological reactions (APRs) and sleep problems, which can compromise health-related quality of life. This study aimed to systematically review literature to identify risk factors for steroid-induced APRs and sleep problems in children with ALL. METHODS A systematic search was performed in six databases. Titles/abstracts were independently screened by two researchers. Data from each included study was extracted based on predefined items. Risk of bias and level of evidence were assessed, using the Quality in Prognosis Studies tool and the Grading of Recommendations Assessment, Development and Evaluation tool, respectively. RESULTS Twenty-four articles were included. APR measurement ranged from validated questionnaires to retrospective record retrieval, sleep measurement included questionnaires or actigraphy. Overall, quality of evidence was very low. Current evidence suggests that type/dose of steroid is not related to APRs, but might be to sleep problems. Younger patients seem at risk for behavior problems and older patients for sleep problems. No studies describing parental stress or medical history were identified. Genetic susceptibility associations remain to be replicated. CONCLUSIONS Based on the current evidence, conclusions about risk factors for steroid-induced adverse psychological reactions or sleep problems in children with ALL should be drawn cautiously, since quality of evidence is low and methods of measurement are largely heterogeneous. A standardized registration of steroid-induced APRs/sleep problems and risk factors is warranted for further studies in children with ALL.

Abstract
OBJECTIVE To fill the gap in the current data on childhood acute lymphoblastic leukemia (ALL) in low-income and middle-income countries. METHODS This study included 106 children between the ages of 1 and 17 years with newly diagnosed ALL monitored between 1999 and 2010. All the patients were treated with the modified St Jude Total 13A treatment plan at the Pediatric Hematology Clinic at Harran University. RESULTS Sixty-eight (64.2%) patients were boys and 38 (35.8%) were girls. The median age at diagnosis was 5.9 ± 3.7 years. Thirty-eight (35.8%) children were classified as standard risk, 53 (39.3%) were intermediate risk, and 15 (14.2%) were high risk. Thirteen (12.3%) children died in induction before the remission date (43 d of remission induction). Of all the 93 (100%) patients who completed remission induction therapy and whose bone marrow were in remission, 5 (4.7%) had a bone marrow relapse, 1 (0.9%) had a retinal relapse, and 5 (4.7%) had secondary acute myeloid leukemia. At a median follow-up of 44 months (range, 0.36 to 135.5 mo), the estimated 5-year overall survival and event-free survival were 77.4 ± 5% and 68.9 ± 6.5%, respectively. The estimated 5-year overall survival for boys and girls was 76.5 ± 6% and 65.8 ± 8%, respectively (P = 0.182). CONCLUSIONS St Jude Total 13A treatment protocols to treat childhood ALL can be successfully adapted, which suggests that such an approach may be useful in low socioeconomic regions; however, it should be noted that secondary leukemia can occur at a high rate.

Abstract
INTRODUCTION Management of refractory chronic lymphocytic leukemia (CLL) represents a major challenge because of the poor prognosis and limited treatment options. While corticosteroids have been used to treat CLL since 1940s, their benefit has never been conclusively proved. Recently, several groups reported use of high-dose corticosteroids (methylprednisolone or dexamethasone) either alone or combined with chemotherapy and/or monoclonal antibodies in relapsed/refractory CLL. AREAS COVERED While efficacy of high-dose corticosteroids is excellent including responses in patients with bulky lymphadenopathy or those considered ultra high-risk CLL because of deletion and/or mutation of p53 gene, the duration of response is still unsatisfactory. Combination with monoclonal antibodies seems to improve therapeutic efficacy but no randomized trials have been conducted. For the purpose of this review, a search for terms, high-dose corticosteroids/methylprednisolone/dexamethasone, and chronic lymphocytic leukemia has been performed in PubMed and database of abstracts from American Society of Hematology Meetings. EXPERT OPINION High-dose corticosteroids appear to play an important role in the management of highly pretreated relapsed/refractory CLL including patients with massive lymphadenopathy. Myelosuppression is usually limited but infectious toxicity, including increased risk of invasive fungal infections, represents the most dreaded side effects. This therapeutic approach should be further tested within large prospective trials, to optimize efficacy and safety.

Abstract
Genotype/allele distributions of leptin promoter G-2548A polymorphism, serum leptin and insulin levels and body weight were not significantly different between 72 children (39 male/33 female; age range 1.08-16, median 6 years) with acute leukemia (56 acute lymphoblastic leukemia [ALL]/16 acute non-lymphoblastic leukemia [ANLL]) at diagnosis and 70 age- and sex-matched controls (p > 0.05). The - 2548GG genotype was associated with the highest leptin levels in controls and patients with acute leukemia after 7-day high-dose methylprednisolone (HDMP) therapy (p < 0.05), while no significant association of genotype with leptin levels was detected in patients at diagnosis (p > 0.05). One-week HDMP therapy in patients carrying the - 2548G allele caused a significant increase in leptin levels and body weight (p < 0.001), whereas increases in those carrying the - 2548AA genotype were insignificant (p > 0.05). Decreases in white blood cell counts of patients after therapy were insignificant in - 2548GG (p > 0.05) yet significant in - 2548GA and - 2548AA (p < 0.05) genotypes. These results revealed no association of leptin genotype with the etiology of childhood acute leukemia but a possible association with leptin levels and effects of HDMP therapy.

Abstract
Vincristine is a commonly used antineoplastic drug and frequently causes neurotoxicity. Here the authors report a 4-year-old boy with acute lymphoblastic leukemia in whom vincristine-induced peripheral and cranial neuropathy developed during remission induction therapy. The patient seemed to benefit from pyridoxine and pyridostigmine therapy greatly and this therapy is recommended in patients with severe vincristine-induced neuropathy.

Abstract
AIM The aim of the study was to evaluate the rate of hepatitis B and C virus infection and emphasize the importance of hepatitis B virus (HBV) vaccination in leukemic children. METHODS One hundred and sixty children who were treated for acute lymphoblastic leukemia (ALL) at Hacettepe University Faculty of Medicine, Pediatric Hematology Unit were included in the study. They were 71 (44.4%) girls and 89 (55.6%) boys with a mean age of 6.45 +/- 3.87 years. RESULTS Of these 160 children, 22 (13.8%) were anti-HBs-positive and 138 (86.2%) were anti-HBs-negative at the diagnosis of ALL. Among the 138 anti-HBs-negative children, 67 (41.9%) were vaccinated for HBV during maintenance chemotherapy, and 71 (44.3%) could not be vaccinated. Two (2.9%) vaccinated and 22 (30.9%) unvaccinated children developed HBV infection during the follow-up period (P < 0.001). Among 160 children treated for ALL, 24 (15.0%) had HBV, three (1.9%) had hepatitis C virus (HCV) infections, and 29 (18.1%) had toxic hepatitis. The majority of patients with HBV or HCV infections had high risk (HR) protocol, whereas most of the patients with toxic hepatitis had low risk (LR) protocol, especially St Jude Total XIII LR protocol. CONCLUSION Viral hepatitis and toxic hepatitis were observed more commonly in the HR and LR group, respectively, of ALL patients. This could be explained by intensive chemotherapy and more heavy blood product administration in the HR group and the chemotherapeutic agents of methotrexate and 6-mercaptopurine, basic drugs used in the LR group. In respect to protection from these complications, periodical liver function tests, serological tests for HBV and HCV, and vaccination for HBV should be performed for all children with ALL.

Abstract
Glucocorticoids (GCs) are known for their clinically useful effects in immunologic and inflammatory disorders. Although there is a huge volume of knowledge concerning the cellular and molecular effects of GCs, statements regarding their effects in multiple diseases at variable doses are not clear-cut owing to pharmacogenetic differences. The main actions of GCs in hematologic disorders have been related to their differentiation-inducing and apoptosis-inducing effects, but modification of several steps of the hematopoietic and/or immune pathway has also been reported. In our clinic, mega-dose methylprednisolone (MDMP) has been successfully used for treatment of different hematologic diseases, such as leukemias, bone marrow failure in aplastic anemia, hypoplastic anemia, myelodysplastic syndrome, neutropenia, autoimmune diseases, and in some congenital hereditary diseases. Both clinical and experimental studies in our department revealed that MDMP was more effective than conventional dose steroids. It is interesting that MDMP can be curative in some congenital hereditary diseases such as Diamond-Blackfan syndrome. However, more research is required to clarify their roles in biology, physiology, and molecular genetics.

Abstract
Myelodysplastic syndrome (MDS) is a clonal hematopoietic stem cell disorder characterized by ineffective hematopoiesis, peripheral cytopenia, and dysplastic changes in the bone marrow. Monosomy 7 or partial loss of 7q is a common cytogenetic abnormality in MDS patients and is associated with poor prognosis. This study examined eight patients with monosomy 7 and MDS. Five MDS patients with monosomy 7 progressed to acute leukemia: three cases transformed into acute myelogenous leukemia (AML) in a mean time of only 4.6 months and two cases into acute lymphoblastic leukemia (ALL) in a mean time of 9 months. To our knowledge, this is the first report showing progression of monosomy 7 associated with MDS to ALL in the childhood period.

Abstract
The authors compare the apoptotic effect on the lymphoblasts and the proliferative effect on the myeloid lineage cells of a short-course high-dose methylprednisolone (HDMP) and the conventional-dose prednisolone treatments in children with acute lymphoblastic leukemia (ALL). The patients were divided into 2 groups. Group I (n = 10) received HDMP (30 mg/kg/day for 7 days) in a single dose before 6 a.m. perorally. Group II (n = 10) received prednisolone (2 mg/kg/day for 7 days) in 3 doses. The apoptotic percentages of lymphpblasts and the percentages of blasts and myeloid lineage cells were determined after performing the bone marrow aspiration (BMA) at diagnosis on the 0th, 3rd, and 7th days of the treatments in all patients. The mean apoptotic percentages of the lymphoblasts on the 3rd day were significantly higher than those on the 0th and 7th days in both groups (p < .05). The highest apoptosis was determined on the 3rd day in group I. The mean percentages of the blast cells on the 7th day were significantly lower than those on the 0th and the 3rd days in both groups (p < .05). The lowest lymphoblast percentage was determined on the 7th day in group I. The mean percentages of the CD13+ and CD33+ cells on the 7th day were significantly higher than those on the 0th and the 3rd days in both groups (p < .05). The highest percentages of the CD13+ and CD33+ cells were found on the 7th day in group I. Prednisolone and HDMP showed no proliferative effect on the CD14+ cells. These findings indicate that a short-course HDMP treatment shows a more effective apoptosis on the lymphoblasts and on the increase of the myeloid lineage cells when compared to the prednisolone treatment. The authors suggest that HDMP may be used in the treatment of patients with ALL instead of prednisolone.

Abstract
Symptomatic hypoglycemia is an unusual complication in children receiving oral purine analogues for treatment of childhood acute lymphoblastic leukemia (ALL). The exact mechanism of the hypoglycemic effect of the antimetabolic therapy remains unclear. Reduced hepatic glycogen stores or impaired hepatic glyconeogenesis may partly explain the hypoglycemia. To prevent hypoglycemia, food containing complex carbohydrates is recommended before sleep. In severe cases of hypoglycemia due to 6-mercaptopurine (6-MP), the dose can be given in the morning and if this fails 6-MP can be discontinued for a short period of time. We report a 3-year-old child who developed severe early morning hypoglycemia episodes that resolved after decreasing 6-MP while receiving non-high risk ALL therapy.

Abstract
Out of 334 children with acute lymphoblastic leukemia who were treated with St Jude Total XI and Total XIII chemotherapy protocols were investigated and 21 (6.3%) were hypertensive. The incidence of tumor lysis syndrome was higher in the hypertensive group than in the nonhypertensive group (28.6% vs. 11.5%) (P = 0.035). There were no differences between patients treated with high-dose methylprednisolone and prednisolone St Jude Total XI and Total XIII, St Jude Total XIII LR and St Jude Total XIII HR groups in respect of the above-mentioned parameters. Central nervous system involvement, skeletal system involvement, abdominal lymphadenopathy, elevated lactate dehydrogenase and leukocyte count, French-American-British types and immunophenotypes were not found to be statistically significant to the development of hypertension (P > 0.05). We found that renal leukemic infiltration is a risk factor in hypertension development (P = 0.04) and hypertension is a risk factor for renal parenchymal disorder in the follow-up period (P = 0.0001). Six patients presenting with hypertension in the first week of disease therapy were evaluated for renal parenchymal disorder and glomerular filtration rate abnormality in the follow-up period. Glomerular filtration rate abnormality was found in 1 and renal scintigraphic dimercaptosuccinic acid abnormalities (reduced uptake and dilated hypoactivity) were found in 4 patients. Hypertension was also found to be a risk factor for renal parenchymal disorder in the follow-up period.

Abstract
We describe a 5-year-old girl showed recovery of vincristine induced cranial polyneuropathy with pyridoxine and pyridostigmine treatment. A 5-year-old girl was diagnosed preB cell Acute Lymphoblastic Leukemia (ALL). She received chemotherapy according to the previously described modified St. Jude total therapy studies XIII. Five days after the fourth dose of vincristine, she presented with bilateral ptosis. Neurological examination revealed bilateral ptosis, and complete external opthalmoplegia with normal pupillary and corneal reflexes. She received 3.8 mg cumulative dose of vincristin before development of ptosis. A neuroprotective and neuroregenerative treatment attempt with pyridoxine and pyridostigmine was initiated. The bilateral ptosis markedly improved after 7 days of pyridoxine and pyridostigmine treatment and completely resolved after two weeks. The both agents were given for 3 weeks and were well tolerated without any side effects. During the follow up period we did not observe residue or recurrence of the ptosis.

Abstract
This study presents retrospective analyses of 20 acute lymphoblastic leukemia (ALL) patients who developed neurologic complications (except leukemic infiltration). These subjects represent 9.9% of 203 ALL patients aged 16 years or younger followed in our hospital between March 1991 and January 2003. Fourteen male and six female patients, whose ages ranged between 6 and 168 months, developed 24 episodes of neurologic complications after the diagnosis of ALL. The most common complication was meningitis, which developed in six (25%) episodes, and two thirds of the patients who had meningitis were evaluated to be iatrogenic. Cerebral infarct and venous thrombosis were detected in five (21%) of the episodes. In two (8%) episodes progressive cerebral dysfunction developed after radiotherapy. The remaining 11 (45%) episodes are due to varying types of complications. Interestingly, one patient had abundant histiocytes exhibiting hemophagocytosis in the cerebrospinal fluid (CSF) examination and this patient was subsequently diagnosed with fungal meningoencephalitis, by further investigation. Six (30%) patients died; epilepsia developed in five (25%) patients in the follow-up period and the remaining nine (45%) are healthy. By close follow-up and effective treatment of thrombosis and, especially, of infections including iatrogenic meningitis in developing countries, the morbidities and mortalities of these complications can be decreased.

Abstract
We have investigated serum endothelin-1 (ET) and nitric oxide (NO) levels before and after a short course of high dose methylprednisolone (HDMP) in children with acute lymphoblastic leukemia (ALL) as an indicator of vasoconstrictor and vasodilator properties of endothelium. Nineteen children with ALL (aged 13-180 months; 5 girls and 14 boys) and 25 healthy children were included in the present study. The children with ALL were given HDMP (20 mg kg 1 day 1) alone for the first 5 days. Serum ET and NO levels were analysed before and after a short course of high dose methylprednisolone. Before treatment, serum ET levels (median 7.6 pg ml 1) of the patients were lower than the healthy controls (13.0 pg ml 1) (p < 0.05), and it rose to similar levels (13.0 pg ml 1) following therapy as in the controls. Nitric oxide levels (7.0 micromol) of the patients were insignificantly higher than the healthy controls (3.9 micromol) and did not differ after treatment (7.0 micromol) (p > 0.05). In conclusion, the elevation of ET to normal level following treatment suggests that a short course of high dose of methylprednisolone improve the endothelial dysfunction caused by acute leukemia.

Abstract
During recent decades, the survival rate after childhood acute lymphoblastic leukemia (ALL) has improved substantially; consequently, the long-term side effects of ALL and its treatment have gained attention, of which osteoporosis is one of the most important. The purpose of the present study was to compare the influence of different treatment protocols that include high-dose methylprednisolone (HDMP) versus conventional-dose prednisolone (CDP) for remission-induction therapy on bone mineral density (BMD) and serum bone turnover markers in survivors of childhood ALL after cessation of chemotherapy. Thirty-six boy and 23 girl survivors, treated for ALL, were cross-sectionally studied, at a mean age of 11.7 years (range 6-19). Group 1 (n = 30) received CDP therapy (prednisolone, 2 mg/kg/day, orally) and group 2 (n = 29) received HDMP therapy (prednol-L, 900-600 mg/m2, orally). All other therapies were similar in both groups. Cranial irradiation was added for high-risk patients as soon as possible after consolidation therapy. We found that mean lumbar spine BMD z score value was -1.75 (0.83) SDS in group 1 and -1.66 (1.21) SDS in group 2. There is no difference between both groups (P = 0.736). The mean BMD z scores of prepubertal and pubertal patients were not significantly different in both groups. Comparison of serum bone turnover parameters of the patients revealed no difference between the two groups. Stepwise regression analysis revealed that lumbar spine BMD z scores was predicted by height SDS and the time past since cessation of therapy, but not age at diagnosis, BMI SDS, cranial radiotherapy, and puberty. Our study results showed that HDMP treatment did not deteriorate the bone mass any more than CDP treatment. These results proved that high-dose steroid therapy over a short period of time in remission-induction treatment would not affect the bone mass any more adversely than would conventional doses approximately 3 years after cessation of chemotherapy.

Abstract
The objective of this study was to determine the frequency of electrolyte perturbations and their relationship with leukemic status before and after chemotherapy in patients with acute lymphocytic leukemia. Blood biochemistry, liver and renal function tests, and renal sonograms were examined at diagnosis and during induction therapy in 334 patients. Renal and electrolyte disturbances were then studied in 116 patients between 3 and 110 months after cessation of the St. Jude chemotherapy treatment protocol. Glomerular filtration rate, electrolyte, protein, and beta-2-microglobulin levels were determined in fresh urine samples, and serum electrolyte levels were examined in blood samples. Renal sonographic examinations and scintigraphic examinations were performed with DMSA and MAG-3. Renal leukemic involvement was detected by sonographic examination in 32 patients who had also presented with hyperphosphatemia or hyperuricemia. Patients with electrolyte disorders at diagnosis were less likely to have tumor lysis syndrome during induction chemotherapy. This may be explained by correction of their electrolyte disorders at the time of diagnosis, which may protect them from tumor lysis syndrome. Hypocalcemia and hyponatremia at the time of diagnosis were found to be significant initial risk factors for renal scan abnormalities and microproteinuria, respectively, during the late therapy period (P < 0.05). Electrolyte abnormalities and renal changes were commonly observed before and after therapy for leukemia. Patients presenting with hypocalcemia and hyponatremia should be examined for microproteinuria and should undergo renal scanning during the late therapy period.

Abstract
A 5-year-old girl developed acute lymphoblastic leukemia (T-ALL) 15 months after being diagnosed with autoimmune hemolytic anemia (AHA), while AHA was in partial remission. AHA was mediated by warm antibodies. Because AHA could not be controlled during the induction therapy of ALL, she was administered immunoglobulin G and plasmapheresis was performed. Hepatomegaly dissappeared in the 4th month. However, anemia requiring blood transfusion, positive direct Coombs' test, and splenomegaly dissappeared in the 13th month of the leukemia treatment; reticulocytosis and decreased haptoglobin level persisted. AHA exacerbated in the 24th month of the ALL therapy. Prednisolone was started but the family refused to continue the therapy. This case presents some features that were not reported before, such that ALL was preceded by AHA and involved T-cell lineage, AHA was mediated by warm antibodies, and the two disorders took place in childhood.

Abstract
In order to evaluate potential long-term kidney damage of childhood leukemia and risk factors affecting renal damage, we studied 116 children treated for acute lymphoblastic leukemia (ALL) using the St. Jude Total XI and XIII protocols in 1991-1998. The median follow-up period after the completion of treatment was 35 months. The following parameters were examined: urinalysis, urinary creatinine (Cr), calcium (Ca), phosphorus, beta2-microglobulin, glomerular filtration rate (GFR), tubular phosphorus reabsorption (TPR), and renal function tests. Radiological evaluation included renal ultrasonography (US), and renal scans with DMSA or MAG-3 were performed. Blood chemistry and renal US patients were normal in all patients except two. GFR, TPR, urinary Ca/Cr, beta2-microglobulin, and renal scan were abnormal in 19.0%, 16.4%, 13.8%, 6.0%, and 40.5% of patients, respectively. The abnormality rate in GFR was significantly higher in patients <2 years of age. TPR abnormality was found to be significantly higher in patients who did not have G-CSF. An abnormal renal scan was associated with Hb < 10 g/dL, kidney infiltration, or hypertension at presentation and also occurred patients who underwent methotrexate treatment with frequent intervals during the follow-up period. Patients should be followed-up after cessation of therapy with the conventional tests mentioned above. In case of any abnormality, further detailed tests should be performed; renal scan seems to be more predictive for renal damage.
