Abstract

Background: Chronic lymphocytic leukemia (CLL) remains an incurable disease with variable course. It is typically responsive to several courses of chemotherapy. Objectives: Evaluation of efficacy of combination of rituximab with chlorambucil plus prednisolone (R-LP) as first line of treatment of CLL patients whom are not fit for treatment with fludarabine combination therapy. Patients & Method: Over 17 months duration, thirty patients with CLL were included in this a cohort prospective study. All of them were received 8 cycles combinations of rituximab (day 1) plus chlorambucil plus predinsolon (day1 to day 5). It had been used for those couldn’t receive or those having intolerance to fludarabin based therapy. At end of courses , re-assessment had performed & included clinical examination ,blood count in addition to BM examination for evaluation of response in term of overall response rate(ORR) ,duration of response(DOR), and treatment free interval(TFI). Results: Overall response rate (ORR) reported in 86.67% of patients. Both anemia &bone marrow lymphocyte percentage has significant relation to the treatment response (p=0.051, p=0.036 respectively) as well as positive direct antiglobulin test( DAT) & diffuse BM infiltration (p=0.033,p=0.04 respectively). Mean duration of response (DOR) is 9.23+0.50 months while mean treatment free interval (TFI) is 11.74+0.64 months. Bone marrow lymphocyte proportion is consistently predictive factor in long term remission durability in negative correlation( r = – 0.47, p= 0.04). Conclusion: Rituximab plus chlorambucil and predinsolon (R-LP) combination therapy might be as good alternative regimen with equivalent response for CLL patients whom are nonsuitable for treatment with fludarabine combination therapy

Abstract

Background: B-Chronic lymphocytic leukemia (B-CLL) is a monoclonal malignancy characterized by an accumulation of terminally differentiated small and anergic B lymphocytes in the blood, bone marrow and other tissues. CLL is typically characterized by CD5+, CD23+, CD22 -, CD79b-, with weak expression of surface Ig. CD5 also is expressed in B1 subset of human B –lymphocytes. Mature B cell malignancies, such as B-cell chronic lymphocytic leukemia, are mostly CD5 +. CD23 promotes the activation and proliferation of normal B lymphocytes and has an important role in the process of malignant transformation in BCLL. CD38 is expressed on the surface of leukemic cells in a significant percentage of patients with B-cell chronic lymphocytic leukemia (B-CLL).Its expression has prognostic value in CLL. The current immunophynotype antigens is used to diagnosed as CLL cases, and by using the modern multicolor Flow Cytometry, which made it possible to determine the expression of several such antigens on specific cell populations of the CLL cases. Objectives: To measure the expression of CD5, CD23, and CD38 antigens on the B-cells of morphologically diagnosed CLL cases, and showing their correlation with the hematological parameters, and with each other. Material and methods: A prospective cohort study including 20 patients including 11 females and 9 males morphologically diagnosed with CLL. The patients were attending the National Center of Hematology, Al-Yarmouk teaching hospital for the period from November 2012 to March 2013. A total of 2 ml of venous blood were collected from all patients who were selected randomly with respect to age, sex, duration and stage of the disease. The diagnosis was done by measuring and calculating the total number of blood cells and lymphocytes and hemoglobin and other by using autoanalyzer blood counter, then flowcytometry was used to measure the appearance of antigens surface CD5 and CD23 CD38. Results: The mean of age of all patients included was 61.95+8.88 SD, and a range of (45-75) years old. There were 11 (55%) males patients, the most common symptoms of patients is an enlarged spleen (45%). 85% of patients who were in Binet stage C, the most advanced stage of the disease. Within Binet stage C there was 94.1% percent of patients showed moderate intensity expression of CD5 and CD23, while 64.7% of them for CD38. There was no statistical significance of CD5, CD23 in relationship to age, hemoglobin or platelet, while CD5 showed a significant relationship with lymphocytes count and the total number of white blood cells (P <0.05).CD38 showed significant relationship with hemoglobin (P <0.05). There is a significant correlation between the CD5 and CD23 P) <0.05), while the CD38 show positive correlation with CD23) P <0.05. Conclusions 1-There is a significant correlation between CD5 expression and absolute lymphocyte count, so higher peripheral blood lymphocyte associated with greater CD5 antigen expression. 2-There is a significant correlation between CD5, and CD23 expression, so high CD5 expression associated with high CD23 expression. 3-There is a significant negative correlation between CD38 expression and Hb level that reflects a prognostic significance. 4-There is a correlation between CD38 expression and CD23 expression. 5-No correlation between the intensity of expression of CD5, CD23, and CD38 and stage of the disease. 6-No correlation between CD38 expression and age, WBC count, and lymphocyte count

Abstract

Background: Lung cancer is one of the major health problems all over the world. Most of cases are discovered at advanced stages because of late appearance of symptoms and the lack of efficient and effective methods for early diagnosis and screening of high risk groups. The microRNA-21(miR-21) was stably present and reliably measurable in all samples of bronchial wash whether positive or negative (control) for lung cancer. Objectives: to evaluate the expressions of the miRNA-21 as a minimally invasive diagnostic biomarker for non-small cell lung cancer (NSCLC). Results: Relative quantification of miR-21 gene showed overexpression in samples positive for NSCLC (non-small cell lung cancer) and ROC study yielding 85% sensitivity and 98% specificity in distinguishing NSCLC patients from controls with p-value < 0.05. Conclusion: altered expressions of the miR-21 in samples of bronchial wash may provide a potential biomarker for detection of non-small cell lung cancer.

Abstract

Background: Venesection or phlebotomy is generally considered to be a safe method, but occasionally adverse effects of varying severity may occur during or at the end of the procedure. Objectives: The aim of the study was to estimate the frequency and type of adverse events occurring during venesection and to assess the practices which would help to minimize them. Materials and methods: This is prospective single-center study was conducted from October 2011 to November 2012 at the emergency unit of the national center of hematology in Baghdad. All phlebotomies procedures made at the center were analyzed. All adverse events occurring during or at the end of procedure were registered by using a standardized questionnaire. Results: Overall 3 adverse events were reported in relation to 960 venesections done, resulting in an overall adverse event rate of 0.3125%, that is, an incidence of 1 in every 320 venesections. One adverse effect was presyncopal symptoms of mild intensity, and the other two that observed were extravasation at site of puncture. Conclusions: Only 0.3% of phlebotomies were complicated by adverse events which were very mild and easily managed. Our study confirms the fact that venesection procedure is a very safe method which could be made even more event-free by following certain friendly, reassuring and competent practices.

Abstract

Background: HGV infects patients at risk for parenteral exposure and chronic blood transfusion, such as those with β- thalassemia major. Objectives: This study was designed to investigate the prevalence of HGV infection in thalassemia patient and furthermore to sequence and analyze phylogentic of HGV. Materials and methods: A prospective study conducted between Feb. to May, 2014. A total of 154 Beta thalassemia patients (87 male; 67 female), from Alkarama teaching hospital and Ibn AL-baladi hospital maternity &children's hospital; aged 18-50 years , who received regular blood transfusions were included in the study. All patients were screened for Antibody against E2 glycoprotein of HGV (Anti-E2 Ab) by using ELISA to detect the presence of HGV infection. While Detection of HGV genomes was done by RT-PCR. Results: One hundred fifty four thalassemia patients (87 male, 67 female) of 18-50 years were involved in this study. Using the ELISA method, Anti-HGV was detected in 16 patients out of 154 (10.4%) with peak prevalence age group was between 20-24 years. Reverse transcription - polymerase chain reaction (RT-PCR) showed HGV-cDNA was detected in 28 (18.2%) only. The peak age prevalence of HGV infection was under 20 years; however, there were no significant differences in prevalence among two sexes or number of blood transfusion. The results of genotyping in 12 randomly selected patients showed presence of genotype 2 and genotype 5 with percentage of 91.7% and 8.3% respectively. Conclusion: the prevalence rate of HGV RNA in β-thalassemia major patients is 18.2%, while the prevalence rate of anti-HGV (past infection) is 10.4%. No one of thalassemia patients had HGV RNA and anti-HGV simultaneously. The Gene sequence analysis of PCR products identified HGV genotypes 2 and 5 with percentage of 91.7% and 8.3% respectively

Abstract

Background: Non –Hodgkin's Lymphoma (NHL) are monoclonal proliferation of lymphoid cells that may be of B-cell (70%) or T-cell (30%) origin and include many discrete entities with characteristic morphological ,immunophenotypical , genetical and clinical features . Hepatitis C Virus (HCV) is a hepatotropic and lymphotropic virus, several studies showed that HCV may chronically infect patients with Non–Hodgkin's Lymphoma with or without producing liver damage. Objectives: To assess the prevalence of hepatitis C virus infection in Iraqi patients with non-Hodgkin's lymphoma and to compare with two control group healthy control and patients had general medical illnesses (unhealthy). Material and method: A prospective case control study included 40 Iraqi patients with NHL. They were tested for the presence of anti-HCV using Enzyme Linked Immunosorbent Assay (ELISA). Positive results were subjected to confirmatory test using Recombinant Immunoblot Assay (RIBA).The diagnosis of NHL cases was confirmed by two consultants histopathologist and they were classified according to the Working formulation system (WF) .Two control groups was applied ; the first included 250 healthy individuals who were age and sex matched while the second group included 50 patients suffering from general medical diseases who were age and sex matched. Result: Four out of 40 patients with Non–Hodgkin's Lymphoma (10%) were positive for anti-HCV, whereas only 1out of 250 healthy individuals (0.4%) were positive for HCV and no patient was positive in the unhealthy control group. Conclusion : The current study revealed the high prevalence of HCV infection in Iraqi patients with Non-Hodgkin's Lymphoma compared to the healthy and unhealthy control groups which support the lymphogenetic role of chronic HCV infection in the pathogenesis of NHL.

Abstract

Background: Acute Myeloid Leukemia (AML) is a clonal hematopoietic disorder, leading to a premature arrest of the normal differentiation of stem cells. C - reactive protein (CRP) is a marker of inflammation. Serum level of C-reactive protein may be increase in patients with AML. This association between CRP levels and acute myeloid leukemia influenced by multiple factors. Acute myeloid leukemia commonly associated with iron overload. Many factors are participating to the hyperferritinemia associated with AML, inflammation chemotherapy, blood transfusion and ferritin hepatic clearance disorders Objectives: To assess serum C-reactive protein (CRP) and iron status (serum Iron, Total iron binding capacity, serum ferritin levels) in patients with acute myeloid leukemia (AML) before and after chemotherapy Materials and Methods: A prospective cohort study included 58 patients (30 male and 28 female) with acute myeloid leukemia with age range (15-65 years). Patients divided into two groups: Group (1) Patients with AML before starting chemotherapy. Group (2) the patients after 4 weeks of chemotherapy In addition to 43 healthy subjects (24 male and 19 female) were included. They were age and sex matched to patients group and considered as controls as (Group 3). This study conducted at the National Center of Hematology and Baghdad Teaching Hospital in the Medical City from February 2014 to June 2014. All patients were subjected to complete history and physical examination. Diagnosis as AML patients was established by complete blood count and blood film, bone morrow aspiration and biopsy. C-reactive proteins. iron, s.total iron binding capacity and s. ferritin were estimated for all .Results: Serum CRP levels increased in AML patients before and after treatment , while there were a significant increase in mean serum ferritin levels observed in (Group 2) compared to newly diagnosis patients (Group 1)(P<0.002) and the levels were significantly higher in newly diagnosis group compared to healthy controls (P<0.015). Patients with (AML) during remission show significant decrease in iron levels compared to newly diagnosis group (P<0.0001), while levels in healthy controls recorded higher values than both (Group 2) and (Group 1) (P<0.0001). Serum total iron binding capacity (TIBC ) levels showed a significant decrease in (Group 2) after treatment compared to (Group 1) before treatment(P<0.0001) but the levels were significantly higher in healthy controls compared to (Group 1) and (Group 2) (P<0.0001) Conclusion: CRP does not predict response to chemotherapy while it may be of benefit in predicting infection or inflammation in patient with AML post chemotherapy. Regarding Iron status: s.ferritin increase significantly post chemotherapy while s.iron and TIBC decrease.

Abstract

ABSTRACT Background: Thalassemia is an autosomal genetic disease leading to anemia and remains one of the major health problems in Southeast Asia and other parts of the world. Almost 100,000 patients with major thalassemia need regular transfusion. Human hemoglobin (Hb) is the molecule that carries and transports oxygen all through the body. Ferritin is the principal iron storage protein, found in the liver, spleen, bone marrow, and to a small extent in the blood. Objectives: The aim of this study was to assess serum ferritin levels in B-thalassemia patients, and to compare it with non-thalassemic anemia and healthy control. Materials and methods: A prospective cross sectional study conducted at Thalassemia Center in Ibn Al- Baladi Hospital for Children and Women during the period from1st February to 30th May 2014 during their attendance to out-patient clinic. A total .number of 101 patients complaining of anemia (51 patients with thalassemia, 50 with non-thalassemia) in addition to 50 healthy subjects considered as control. All patients were tested for Serum ferritin levels and all results were obtained through automated quantitative test for use Vidas machine Results : The mean serum ferritin levels in cases of thalassemia was 9542 + 782 ng/ml while serum ferritin levels in control sample was 138 +323 ng/ml in male and 28+ 108 ng/ml in female . in patients with non-thalassemia anemia, the levels of serum ferritin was 1+80 ng/ml. Age of all patients in this study ranged from 3day-9year .the age of thalassemia patients ranged from 1-6 year and p-value was(0.23) while the age of patients with non-thalassemia anemia was 1-5 year and p-value was (0.11). Conclusion: This study confirm that serum ferritin is high in patients wih thalassemia than non thalassemia.

Abstract

Background: Hair loss affects over 25% of women in developed countries. Three hair disorders, androgenetic alopecia, telogen effluvium and alopecia areata which account for most cases of nonscarring alopecia in women. Iron deficiency has been reported in the majority of women presenting with diffuse hair loss. Iron has important function in oxidationreduction reactions, collagen synthesis, and as a co-factor for enzymes. Objectives: To assess the percentage of the low serum ferritin hair loss females and their response to oral iron replacement therapy. Materials and methods: a prospective cohort study conducted in at Marjan teaching hospital from August 2013 to January 2015. It included 72 female complained from diffuse hair loss were enrolled in this study. Full history was taken from all patients and physical examinations were done both general examination and local examination of the scalp including pull test. Patients were sent to complete blood examinations, serum ferritin. Patients divided in to three groups according to their response to treatment. Before the treatment the severity of hair loss was assess by VAS. Results: Fifty two patients met criteria of inclusion. Their serum ferritin levels range between (1.4-14.4) with mean 6.16±3.30 their hemoglobin levels were (8.3-13.4) with mean ±SD 11.98±1.22. Group I patients included 27 patients (51.9%), their severity of hair loss before treatment was assess by VAS which was 9.18±0.84, after two week of treatment the score become 7.33±1.03, P value is < 0.0001; confidence interval 95% = ( 1.477 to 2.277). in group II patients which included 12 patients (23%), their severity of hair loss before treatment was assess by VAS which was 9.33±0.49, after two week of treatment the score become 9.08±0.66, P value is 0.081 considered not significant; confidence interval 95% = (-0.037 to 0.537). The other thirteen patients (25%) represented the third group. All the patients in this group didn’t show any response to treatment Conclusion: Measurement of serum ferritin level should be done to all patients with chronic telogen effluvium before starting other anti-hair loss modalities. Iron replacement is a safe drug with a few side effects and indicated to all females with low serum ferritin level.
