Pattern of karyotypic aberrations in pakistani patients with de novo acute myeloid leukemia

Background: Acute myeloid leukemia [AMI] is a malignant disease of the bone marrow in which karyotypic analysis is the most important diagnostic and prognostic tool for predicting remission rate, relapse and overall survival. This study was carried out to determine the frequency and type of cytogenetic aberrations in de novo acute myeloid leukemia in adults at a tertiary care hospital

Materials and methods: This descriptive cross-sectional study was carried out in the Hematology Department, Liaquat National Hospital from November 2014 to April 2016.A total of 51 cases were diagnosed with AMI during the study period. Cytogenetic analysis was carried out by banding technique on bone marrow aspirate samples

Results: The mean age of the study subject was 42.03+/-17.70 years. Frequency of karyotyping abnormalities was observed in 47% of cases, in which most frequently occurring cytogenetic abnormalities were those of good cytogenetics including t[15;17] and t[8;21], seen in 23.5% and 9.8% of cases respectively. Intermediate risk cytogenetics including Del 9q was seen in 1.96% of cases. However, poor risk cytogenetics including complex cytogenetics, t[11;q23] and del [13] were seen in 7.8%, 1.96% and 1.96% of cases respectively. Normal cytogenetics was seen in 27 [52.9%] patients

Conclusion: Karyotyping is one of the most important diagnostic and prognostic tools and a maximum benefit could be attained through cytogenetic analysis. Cytogenetic aberrations in our series are more or less similar as reported at national level with preponderance of good risk cytogenetics in our setting

Serum Fasting Lipid Profile In Children And Adolescents With -Thalassaemia Major In Southern Pakistan

Objective: Serum fasting lipid profile has been studied in various clinical spectrum of Beta (β)- thalassaemia syndrome. Premature cardiac impairment in thalassaemia major appears primarily due to iron accumulation and oxidative injury; however it might be a sequel of abnormal lipoprotein concentrations. The rational of this study is to analyse the serum fasting lipid profile in cardiovascular disease free β-thalassaemia major (β-TM) patients. Relationships with age, gender, haematological parameters, liver enzymes and serum ferritin were observed. Method: Fasting serum lipid levels, liver function test (LFT), complete blood count (CBC) and serum ferritin were measured in 36 patients with homozygous β-TM from March 2012 to March 2014. Patients were stratified into two groups, age ≤15 and >15 years, to determine the possible lipid profile distinction in relation to age. Results: 17 were males and 19 were females, with median age of 12.0 years. The mean total cholesterol (TC) and triglyceride (TG) were 5.01±1.32 and 8.36±5.28 mmol/L respectively. High TG was detected in 36.1%, while high density lipoprotein cholesterol (HDL) and low density lipoprotein cholesterol (LDL) were markedly low, 0.98±0.51 and 2.35±1.22 mmol/L respectively. No statistically significant difference was noted between the two age groups. The median TC to HDL ratio (TC:HDL) was elevated, 5.7 (4.0). We established significant correlation of total bilirubin with TC (r=-0.4), HDL(r=-0.5) and LDL (r=-0.4) (P<0.05). Conclusion: Dyslipidaemia in β-TM patients is irrespective of age and gender including low HDL and high TC:HDL, whilst high TC:HDL may contribute as a significant risk marker for future cardiac events in these patients.
