Abstract
Background Recurrent genetic alterations contributing to leukemogenesis have been identified in pediatric B-cell Acute Lymphoblastic Leukemia (B-ALL), and some are useful for refining classification, prognosis, and treatment selection. IKZF1plus is a complex biomarker associated with a poor prognosis. It is characterized by IKZF1 deletion coexisting with PAX5, CDKN2A/2B, or PAR1 region deletions. The mutational spectrum and clinical impact of these alterations have scarcely been explored in Mexican pediatric patients with B-ALL. Here, we report the frequency of the IKZF1plus profile and the mutational spectrum of IKZF1, PAX5, CDKN2A/2B, and ERG genes and evaluate their impact on overall survival (OS) in a group of patients with B-ALL. Methods A total of 206 pediatric patients with de novo B-ALL were included. DNA was obtained from bone marrow samples at diagnosis before treatment initiation. A custom-designed next-generation sequencing panel was used for mutational analysis. Kaplan-Meier analysis was used for OS estimation. Results We identified the IKZF1plus profile in 21.8% of patients, which was higher than that previously reported in other studies. A significantly older age (p=0.04), a trend toward high-risk stratification (p=0.06), and a decrease in 5-year Overall Survival (OS) (p=0.009) were observed, although heterogeneous treatment protocols in our cohort would have impacted OS. A mutation frequency higher than that reported was found for IKZF1 (35.9%) and CDKN2A/2B (35.9%) but lower for PAX5 (26.6%). IKZF1MUT group was older at diagnosis (p=0.0002), and most of them were classified as high-risk (73.8%, p=0.02), while patients with CDKN2A/2BMUT had a higher leukocyte count (p=0.01) and a tendency toward a higher percentage of blasts (98.6%, >50% blasts, p=0.05) than the non-mutated patients. A decrease in OS was found in IKZF1MUT and CDKN2A/2BMUT patients, but the significance was lost after IKZF1plus was removed. Discussion Our findings demonstrated that Mexican patients with B-ALL have a higher prevalence of genetic markers associated with poor outcomes. Incorporating genomic methodologies into the diagnostic process, a significant unmet need in low- and mid-income countries, will allow a comprehensive identification of relevant alterations, improving disease classification, treatment selection, and the general outcome.

Abstract
BACKGROUND In Mexico, the incidence of acute myeloid leukemia (AML) has increased in the last few years. Mortality is higher than in developed countries, even though the same chemotherapy protocols are used. CCAAT Enhancer Binding Protein Alpha (CEBPA) mutations are recurrent in AML, influence prognosis, and help to define treatment strategies. CEBPA mutational profiles and their clinical implications have not been evaluated in Mexican pediatric AML patients. AIM OF THE STUDY To identify the mutational landscape of the CEBPA gene in pediatric patients with de novo AML and assess its influence on clinical features and overall survival (OS). MATERIALS AND METHODS DNA was extracted from bone marrow aspirates at diagnosis. Targeted massive parallel sequencing of CEBPA was performed in 80 patients. RESULTS CEBPA was mutated in 12.5% (10/80) of patients. Frameshifts at the N-terminal region were the most common mutations 57.14% (8/14). CEBPA biallelic (CEBPA BI) mutations were identified in five patients. M2 subtype was the most common in CEBPA positive patients (CEBPA POS) (p = 0.009); 50% of the CEBPA POS patients had a WBC count > 100,000 at diagnosis (p = 0.004). OS > 1 year was significantly better in CEBPA negative (CEBPA NEG) patients (p = 0.0001). CEBPA POS patients (either bi- or monoallelic) had a significantly lower OS (p = 0.002). Concurrent mutations in FLT3, CSF3R, and WT1 genes were found in CEBPA POS individuals. Their contribution to poor OS cannot be ruled out. CONCLUSION CEBPA mutational profiles in Mexican pediatric AML patients and their clinical implications were evaluated for the first time. The frequency of CEBPA POS was in the range reported for pediatric AML (4.5-15%). CEBPA mutations showed a negative impact on OS as opposed to the results of other studies.

Abstract
Background: Acute myeloid leukemia (AML) is the second most frequent leukemia in childhood. The FLT3 gene participates in hematopoietic stem cell proliferation. FLT3 mutations are recurrent in AML and influence prognosis. In Mexican pediatric AML patients, FLT3 mutational profile, and their clinical impact have not been evaluated. Aim of the study: This study aimed to identify the profile of FLT3 mutations in pediatric patients with de novo AML and to assess their possible influence on overall survival (OS) and other clinical features. Methods: Massive parallel target sequencing of FLT3 was performed in 80 patients. Results: FLT3 mutations [internal tandem duplication (ITD) or tyrosine kinase domain (TKD)] were identified in 24% of them. OS was significantly lower in FLT3 POS cases than in FLT3 NEG (p = 0.03). The average OS for FLT3 POS was 1.2 vs. 2.2 years in FLT3 NEG. There were no significant differences in the children's sex, age, percentage of blasts in bone marrow aspirate, or white blood cell count in peripheral blood at diagnosis between both groups. No differences were identified stratifying by the mutational load (high > 0.4) or type of mutation. The negative effect of FLT3 mutations was also observed in patients with acute promyelocytic leukemia (APL). Conclusions: FLT3 mutational profile is described in Mexican pediatric AML patients for the first time. Mutated FLT3 negatively impacts the outcome of AML patients, even considering the APL group. The clinical benefit from treatment with tyrosine kinase inhibitors in the FLT3 POS pediatric patients needs to be assessed in clinical trials. FLT3 testing may contribute to better risk stratification in our pediatric AML patients.

Abstract
Severe dengue pathogenesis is not fully understood, but high levels of
proinflammatory cytokines have been associated with dengue disease severity. In this
study, the cytokine levels in 171 sera from Mexican patients with primary dengue
fever (DF) and dengue haemorrhagic fever (DHF) from dengue virus (DENV) 1 (n = 116)
or 2 (n = 55) were compared. DF and DHF were defined according to the patient’s
clinical condition, the primary infections as indicated by IgG enzymatic immunoassay
negative results, and the infecting serotype as assessed by real-time reverse
transcription-polymerase chain reaction. Samples were analysed for circulating levels
of interleukin (IL)-12p70, interferon (IFN)-γ, tumour necrosis factor (TNF)-α, IL-6,
and IL-8 using a commercial cytometric bead array. Significantly higher IFN-γ levels
were found in patients with DHF than those with DF. However, significantly higher
IL-12p70, TNF-α, and IL-6 levels were associated with DHF only in patients who were
infected with DENV2 but not with DENV1. Moreover, patients with DF who were infected
with DENV1 showed higher levels of IL-12p70, TNF-α, and IL-6 than patients with DHF
early after-fever onset. The IL-8 levels were similar in all cases regardless of the
clinical condition or infection serotype. These results suggest that the association
between high proinflammatory cytokine levels and dengue disease severity does not
always stand, and it once again highlights the complex nature of DHF
pathogenesis.

Abstract
The performance of the novel commercial test ASSURE® Dengue IgA Rapid test (MP Diagnostics) was evaluated using a panel of 172 sera collected from dengue patients and 47 sera from healthy blood donors. The overall specificity and sensitivity were 61.0% and 85.1%, respectively. However, the positivity rate for IgA went from 33.3% for sera collected the same day of fever onset to 81.2% for sera collected 5 days after fever onset. Infections with serotype 2 viruses were detected more efficiently than those with serotype 1 viruses, and no sera from infections with serotypes 3 and 4 were available. In addition, the kit was twice more efficient at detecting secondary infections than at detecting primary infections. Finally, the ASSURE® test showed good repeatability and reproducibility. The results of this study suggest that the ASSURE® Dengue IgA Rapid test may become a useful and easy-to-use test for early dengue diagnosis.

Abstract
OBJECTIVE To identify the main age of onset of different malignant tumors in childhood and to describe the distribution of the different tumors in each pediatric age group. MATERIAL AND METHODS Descriptive survey was used. We reviewed the files of six Mexico City hospitals from 1980 to 1992. We included 4595 cases divided into 13 types of cancer. Peak age was defined when in that year we encountered a frequency equal to or below 10 % of the cases. RESULTS Peak ages for hepatic, sympathetic nervous system, germ cell tumors, retinoblastoma and rhabdomyosarcoma were between 2 and 3 years of age. Wilms' tumor appeared between the first and fourth years; central nervous system tumors between 4 and 5 years; acute lymphoblastic leukemia between 2 and 4 years; non-Hodgkin's lymphomas between 3 and 6 years; Hodgkin's disease between 4 and 8 years; bone tumors between 10 and 14 years. In acute myeloid leukemia and carcinomas no age peak was found. CONCLUSIONS Lymphomas present an age peak different from that reported in developed countries. In neonates and infants, the most frequent tumor was retinoblastoma.
