INTRODUCTION:
Sickle cell anemia (SCA) is an autosomal recessive illness caused by the formation of abnormal hemoglobin S. Sickle cell disease has many complications such as vaso-occlusive crisis (VOC), gallstones, stroke, acute chest syndrome (ACS), and others.
OBJECTIVES:
This study aimed to describe the epidemiology and characteristics of sickle cell patients admitted to hospitals in Jazan region.
MATERIALS AND METHODS:
A cross-sectional study conducted in four hospitals in Jazan region including King Fahad Central Hospital, Prince Mohammed Bin Nasser Hospital, Sabya, and Abu-Arish General Hospital to estimate the prevalence of admitted sickle cell patients and their characteristics. All patients admitted to medicine and pediatric wards from July 15, 2018, to August 15, 2018, were included in the study. Data were collected by interview.
RESULTS:
Four hundred and two of 446 patients have agreed to participate with a response rate of 90%. Ninety-one (22.6%) were SCA patients, among them, 45 (49.5%) were male and 46 (50.1%) were female, with a mean age of 18.81 ± 11.05 years. Most of them were admitted due to VOC 56% (
n
= 51) and ACS 12.1% (
n
= 11). Almost all sickle patients had VOC 91.2% (
n
= 83), and more than half of them had ACS 58.2% (
n
= 53) as a complication.
CONCLUSIONS:
SCA was the number one cause of admissions in this study. Approximately, one out of each four patients admitted to Jazan hospitals is a sickle cell patient. VOC represents the most frequent complication of sickle disease, followed by ACS. Further studies and interventions to reduce this burden and improve sickle cell patients' health status are recommended.

Association of ABO Rh blood group with dengue fever and dengue hemorrhagic fever: A case-control study
Vitthal Khode, Goutam Kabbin, Komal Ruikar
October-December 2013, 4(4):145-148
DOI
:10.4103/1658-5127.127899
Background:
Data on frequency distribution of ABO Rh blood group in pediatric dengue patients are not available. Dengue disease an emerging arthropod borne infection of public health concern belongs to Flaviviridae. The studies defining the relationship between blood groups and dengue disease and its severity are limited. Blood group antigens are generally known to act as receptors for various etiological agents. Hence, we hypothesized there will be an association between blood group and dengue disease and its severity and conducted this case-control study.
Study Design:
Hospital-based case-control study.
Materials and Methods:
Study was conducted in department of pediatrics, 244 pediatric subjects (age group 1 - 13 years) were enrolled divided into cases who were admitted cases of dengue (119, 65 males, 64 females) and controls who were attending outpatient department for various other ailments. (125, 67 males, 58 females) and demographic data (age, gender, blood group, and dengue infection status) were collected from them. The risk of acquiring dengue disease and severity and its association with factors such as blood group, gender were analyzed statistically.
Results:
The data of this study showed a possible association between blood groups of the study population with dengue infection. We observed that dengue infections were higher in individuals with O positive blood group 42.8% when compared with controls 32%. (
P
= 0.043) But blood groups were not associated with severity of infection. These data present further evidence for the association of the blood groups, gender to susceptibility to dengue infection. Further studies are needed to confirm these findings.
Conclusion:
Dengue disease is more common with blood group O. But severity of the disease is not associated with any blood groups.

Lamiaa Al-Jamea, Alexander Woodman, Elmoeiz A Elnagi, Sultan S Al-Amri, Abdulrahman A Al-Zahrani, Njoud H Al-shammari, Rawan A Al-zahrani, Fatimah S Al-Yami, Sultan A Al- Ameri
October-December 2019, 10(4):126-133
DOI
:10.4103/joah.joah_44_19
OBJECTIVES:
This study's objectives are to (1) determine the current prevalence of iron-deficiency anemia (IDA) and risk factors for female college students at Prince Sultan Military College of Health Sciences (PSMCHS) in the Eastern Province of Saudi Arabia and (2) address the gap in the current literature. A written survey in both Arabic and English was administrated to 214 female students, and only 201 students completed the survey. It was randomly selected from all registered female students. A number of factors possibly associated with IDA were examined using the Chi-square test.
CONTEXT:
Globally, iron deficiency is known to be the most common nutritional disorder. About 30% of the world's population are iron deficient (ID). Women seem to be more affected with IDA than men, which constitute an epidemic public health issue.
AIMS:
The aim of the study was to determine the prevalence of IDA and the risk factors among healthy Saudi undergraduate female college students studying at PSMCHS in Dhahran.
SETTINGS AND DESIGN:
A cross-sectional study on 201 female students (18–25 years) was conducted between January and March 2019.
SUBJECTS AND METHODS:
A questionnaire which contains sociodemographic data was completed by each participant. Two blood samples were collected from each participant to estimate the iron profile and to analyze the complete blood counts.
STATISTICAL ANALYSIS:
The statistical analysis was carried out using the Statistical Packages for the Social Sciences software.
RESULTS:
The overall prevalence of IDA was 35.3%. The questionnaire analysis of the dietary habit and clinical characteristics revealed that family history of hereditary disease and physical activity have a significant effect on the development of IDA. Statistical analysis showed that having breakfast regularly significantly reduced the development of IDA compared with irregularly having breakfast.
CONCLUSIONS:
The prevalence of IDA in this study was moderately high, and our results suggest that further education regarding IDA is highly encouraged. This is the first study that demonstrated the prevalence and risk factors of IDA among undergraduate female college students in PSMCHS, and the data generated will provide a database for further studies.

Indira Shastry, Sushma Belurkar
April-June 2019, 10(2):61-66
DOI
:10.4103/joah.joah_13_19
AIMS:
To analyze various changes in the red blood cell (RBC) parameters in patients with chronic kidney disease (CKD) and to correlate it with the stage of the disease.
MATERIALS AND METHODS:
The following parameters were analyzed in 300 diagnosed cases of CKD: RBC count; hemoglobin (Hb); hematocrit; mean corpuscular volume (MCV); mean corpuscular hemoglobin (MCH); MCH concentration (MCHC); serum iron profile (serum total iron, total iron-binding capacity, and serum ferritin levels); and peripheral smear, blood urea, and serum creatinine levels. The data were retrieved from the laboratory information system, and SPSS version 20 was used for statistical analysis.
RESULTS:
The mean age of presentation was 52 ± 14 years. The male-to-female ratio was 4.3:1. The mean RBC count was 3.29 ± 0.79 × 10
6
/μl, and a significant fall was noticed as the stage of CKD progressed. 74% and 60% of patients with Stage 4 and 5 CKD, respectively, showed Hb of <10 g/dl. Correlation of MCV, MCH, and MCHC values with stages of CKD was statistically not significant. One hundred and six (59%) patients had anemia of chronic disease as per the serum iron profile. 94% of patients showed normocytic normochromic RBC picture on peripheral smear and 21% showed features of hemolysis.
CONCLUSION:
Anemia is a leading cause of morbidity in patients with CKD and it worsens with the stage of the disease. Evaluation of Hb and RBC parameters in patients with CKD helps in classifying the type of anemia and aids in choosing the correct treatment modalities and avoids unnecessary iron overload in these patients.

Hereditary methemoglobinemia manifesting in adolescence
Mazen A Badawi, Maha A Badawi, Siraj O Wali, Rajaa Z Alsaggaf
July-September 2016, 7(3):108-110
DOI
:10.4103/1658-5127.192983
Methemoglobinemia is an uncommon cause of cyanosis that may present at any age. Although acquired methemoglobinemia secondary to exposure to oxidative stressors is the most common cause of methemoglobinemia in adults, hereditary methemoglobinemia has to be considered in patients presenting with cyanosis during infancy and childhood. We report the case of a patient who was investigated for cyanosis that was only noted at the age of 15 years. Despite the negative family history, he was diagnosed with hereditary autosomal recessive methemoglobinemia with no other factors that can be identified to cause such an elevation of methemoglobin level. This case illustrates that hereditary methemoglobinemia has to be considered in such patients even if they were completely asymptomatic for many years of their lives.

and
Methods:
A cross-sectional study was conducted among 1000 health care medical students at Anand, Gujarat, India using a structured survey questionnaire.
Statistical
Analysis
Used:
The data were tabulated, and master chart was prepared. Analysis was performed by using the percentage.
Results:
Overall knowledge on blood donation among respondents was 37.3%, majority of the participants (78.7%) never donated blood in which 43.7% of the nondonors had negative attitude like blood donation leads to weakness (10.2%), anemia (25.5%), and 8.0% of nondonors felt that blood donation leads to reduced immunity. Majority of nondonors showed a positive attitude (53.1%) by expressing their willingness to donate blood if they were asked to donate blood (35.3%), about 9.8% of the nondonors don't know the importance of blood donation and 11.2% of nondonors don't know where to donate blood. In this study, 11.5% of students had donated blood only once, in which 38.8% of blood donors said no privacy was provided while donation, few (12.2%) had experienced some discomfort after donation and 50.4% of respondent said that they have not tried again.
Conclusions:
The present study recommends that even health care students' needs to be educated about the importance, awareness and motivation of blood donation on a regular basis and addressing the problems faced, while blood donation will strengthen the recruitment and retention of blood donors to donate blood on a regular basis.

Context:
Pancytopenia is not a disease but a clinico-hematological entity encountered in clinical practice. A prompt intervention is required to avoid complications, which can occur in these patients. The relevant clinical history and complete hematological workup is required to treat patient of pancytopenia. The severity of pancytopenia and the underlying pathology determines the management and prognosis.
Aims:
To diagnose different conditions producing pancytopenia on the basis of clinical, hematological and bone marrow studies. To estimate the frequency of different diseases producing pancytopenia.
Subjects and Methods:
The study was conducted in Department of Hematology of our college in capital city of India. A prospective study was carried out among 100 consecutive patients with pancytopenia. Blood samples of the patients were analyzed for red cells, white cells and platelets morphology along with presence and absence of immature cells and abnormal cells. In bone marrow examination, morphology of all cells lineage, cellularity, parasite and abnormal cells were scrutinized. Trephine biopsy was done where ever indicated.
Results:
The age of patients ranged from 5 to 80 years. 74% of patients in this study were vegetarian. The most common cause of pancytopenia was megaloblastic anemia (66%) followed by aplastic anemia (18%), malaria (6%), kala-azar (4%), acute myeloid leukemia (2%), multiple myeloma (2%), myelodysplastic syndrome (1%), and tuberculosis (1%).
Conclusions:
The present study concludes that detailed primary hematological investigations along with bone marrow examination in cytopenic patients is helpful for understanding disease process, to diagnose or to rule out the causes of pancytopenia. It is also useful in planning further investigations and management.

Impact of fetal hemoglobin on micronutrients in sickle cell anemia
Mathias Abiodun Emokpae, Maryam Omo Musa
April-June 2015, 6(2):74-78
DOI
:10.4103/1658-5127.160205
Background
/
Objective:
The presence of persistent high fetal hemoglobin (HbF) in sickle cells disease (SCD) patients may be a modulator of clinical and biochemical features. This study seeks to test the hypothesis that high level of HbF may regulate the levels of calcium, magnesium, zinc, and copper in SCD patients in a steady clinical state.
Materials
and
Methods:
Serum calcium, magnesium, zinc, and copper were assayed in 100 SCD patients in steady clinical state and 50 control subjects using the colorimetric method while blood HbF was determined by alkaline denaturation method.
Results:
Twenty-five percent of the study group had high (>5%) HbF, while 75% had low (<4.9%) HbF levels. HbF (
P
< 0.001), serum copper (
P
< 0.001), and calcium (
P
= 0.002) were significantly higher in SCD patients compared with controls, while zinc and magnesium were significantly lower (
P
< 0.001) in SCD patient compared with controls. Serum calcium (
P
= 0.01) and copper (
P
= 0.118) were lower in SCD patients with high (≥5%) HbF while magnesium and zinc were significantly higher (
P
< 0.001) in SCD patients with high HbF compare with those with low (≤4.9). HbF correlated negatively with calcium (
r = −0.25,
P = 0.011) and copper
(r
= -0.11,
P
= 0.287) while magnesium (
r
= 0.60,
P
= 0.001) and zinc (
r
= 0.57, P < 0.001) correlated positively on HbF levels.
Conclusion:
HbF levels may have modulated the levels of these elements in SCD patients. It is suggested that HbF may be estimated along with hemoglobin electrophoresis in diagnosis, clinical management, and predicting clinical course of SCD patients. Nutritional studies may be routinely conducted in this group of patients for better management.

Deepika Chenna, Shamee Shastry, Mohandoss Murugesan, Poornima B Baliga
July-September 2015, 6(3):111-114
DOI
:10.4103/1658-5127.165649
Background and Objectives:
Donor screening process is one of the most important steps in protecting the safety of blood supply. Donors who do not meet specified criteria are deferred either temporarily or permanently. These criteria are designed to protect both donors and patient safety. Due to the varied rates and reasons for deferrals in the existing literature, we aimed to evaluate the patterns and prevalence of deferrals in our institution.
Materials and Methods:
This retrospective study was conducted at a Tertiary Care Hospital, Karnataka, Southern India, to evaluate the various reasons for blood donor deferral from January 2011 to January 2014. Demographic data of blood donors was obtained through the blood bank database and secondary measures such as the type of deferral (permanent/temporary, pathogenic/nonpathogenic, and harmful to donor/recipient) were assessed.
Results:
A total of 54,653 subjects presented to our blood bank during this period out of which 2935 (5.6%) were deferred. The deferral to donor percentage was higher in females (36.54%) than males (3.64%). Low hemoglobin was the major deferral criterion seen in our participants (48.1%) followed by hypertension (16.4%), underweight (8.9%). Low pulse rate and fasting donor were the least prevalent reasons. A total of 36.8% of reasons for deferral were harmful to donors, 88.2% were nonpathogenic, and 98.1% were temporary causes.
Conclusion:
Variations in donor deferral may be attributed to different donor selection criteria in different regions and centers. Hence, it is important to know the common causes of donor deferral in a region so that measures may be taken to improve the donor pool.

Elevated levels of pro-coagulant microvesicles in children in-steady state sickle cell disease
Hassan A Hamali, Orwa G Elhussein, Abdulmoneim Jamil, Sadaqat Hussain, Mubarak Alshraim, Abdulrahman Alshehri
July-September 2015, 6(3):115-118
DOI
:10.4103/1658-5127.165650
Introduction:
Sickle cell disease (SCD) is an inherited genetic disorder characterized by various complications, including thrombosis. Increased levels of circulating microvesicles (MVs) and tissue factor (TF)- bearing MVs have been reported in SCD.
Objectives:
The present study compares the levels of circulating MVs and TF- bearing MVs in steady state SCD children with age- and gender- matched healthy controls using an indirect ELISA. Citrated whole blood was collected from 54 SCD patients homozygous for sickle haemoglobin (HbSS) (aged from 2 to 12 years-old) and 34 healthy controls.
Results:
SCD patients showed significantly higher levels of MVs in their plasma as compared to the controls (
P
= 0.0095). Although the TF activity on MVs was low in both groups, there was a significant difference between them
P
<0.05). A strong correlation between the level of MVs and TF-MVs in the patient group was also noted.
Conclusion:
This suggests their involvement in the hypercoagulable state in the study group of patients. Further studies are recommended to elucidate the functional activity of MVs and TF-MVs, as well as the size and origin of MVs in the plasma.

Rahman A Bolarinwa, John C Aneke, Samuel A Olowookere, Lateef Salawu
October-December 2015, 6(4):162-167
DOI
:10.4103/1658-5127.171985
Background:
The risk of acquiring transfusion transmissible viral infections is said to be higher in patients requiring regular blood transfusions such as those with sickle cell disease (SCD).
Aim:
We determined the seroprevalence of blood transfusion viral markers among our patients with SCD.
Subjects and Methods:
This a case–control analytical study consisting of 82 confirmed SCD patients on routine follow-up at our facility in steady state and 90 age-matched controls. Demographic and transfusion history were recorded while 5 ml of blood was drawn for hematocrit levels, and serum tested for transfusion transmissible viral markers for hepatitis B, (hepatitis B surface antigen [HBsAg], hepatitis B surface antibody [HBsAb], hepatitis B e antigen [HBeAg], hepatitis B e antibody [HBeAb], hepatitis B core antibody [HBcAb]), hepatitis C virus (HCV) and human immunodeficiency viruses (HIVs) using the rapid test kits. Ethical approval for the study was obtained from the Institutional Review Board and each participant gave informed consent. Data were analyzed using descriptive and inferential statistics.
Results:
The seroprevalence of HBsAg, HBsAb, and HBeAg in cases was 2 (2.4%), 7 (8.5%), and 0 (0.0%), respectively, whereas it was 7 (8.5%), 11 (13.4%), 6 (7.3%), and 2 (2.4%) for HBeAb, HBcAb, HCV, and HIV antibodies. Compared to the controls, cases had higher prevalence rate of HBeAb (
P
= 0.005). No significant difference was observed in those with or without low hematocrit (≤18%) or those that received blood transfusion and those that did not (
P
> 0.05).
Conclusion:
We conclude that blood transfusion did not significantly increase the seroprevalence of markers of transfusion transmissible viral infection in SCD patients.

Wasil Jastaniah, Abdulrahman Alsultan, Saad Al Daama, Walid Ballourah, Mohammad Bayoumy, Faisal Al-Anzi, Omar Al Shareef, Mohammed Burhan Abrar, Reem Al Sudairy, Ibrahim Al Ghemlas
April-June 2017, 8(2):41-48
DOI
:10.4103/joah.joah_16_17
Background:
Despite the confirmed favorable prognosis of childhood
t
(8;21) acute myeloid leukemia (AML), recent reports suggest heterogeneity in survival outcomes in this subtype of AML may be influenced by ethnicity. Therefore, we aimed to assess the outcome of childhood
t
(8;21) AML in an Arab population to evaluate if survival outcomes were inferior and determine the predictive relevance of additional cytogenetic abnormalities.
Methods:
This multicenter retrospective study analyzed 175 de novo AML children of 14 years of age or younger consecutively diagnosed between January 2005 and December 2012. Survival outcomes were analyzed and patients with
t
(8;21) were stratified on the basis of karyotype into sole and additional cytogenetic groups.
Results:
A total of 33 (18.9%) patients had
t
(8;21) AML. Complete remission (CR) was achieved in 31 (93.9%) patients. The 5-year overall survival, event-free survival, cumulative incidence of relapse (CIR), and remission death rates were 59.9 ± 9.2, 45.6 ± 9.1, 36.4, and 9.1%, respectively. Despite the administration of hematopoietic stem-cell-transplant salvage therapy in first relapse, five out of 11 (45.5%) relapsed patients died of disease. Subanalysis of sole vs. additional cytogenetic abnormalities revealed no significant difference in outcome.
Conclusion:
In the present study, childhood
t
(8;21) AML was associated with inferior survival and resistance to salvage therapy compared to reports from international groups. The inferior outcomes were unrelated to additional cytogenetic abnormalities. Further detailed genetic studies are warranted to unmask the biological and clinical differences between racial/ethnic groups. Given the high CR rate of childhood
t
(8;21) AML, further modification of postremission therapy to improve the CIR rate is needed.

Introduction:
Sickle cell anemia (SCA) is one of the most common genetic diseases worldwide. Patients with SCA present with varied clinical features and complications that may affect many organs in the human body. There are few treatment options for SCA, and patient responses vary; the only curative therapy is a stem cell transplant or gene therapy. We seek to study the clinical features and treatment options for patients with sickle cell disease treated in King Abdulaziz Medical City, Riyadh.
Methods:
This study was a retrospective cohort study of all adult SCA patients who were admitted to our institution during the period from 1983 to 2016. Data were entered into Excel spreadsheets and managed with SPSS. Chi-square test was used to compare responses to therapy and in patients with different presentations.
Results:
A total of 106 patients with sickle cell disease were included in this study. The percentages with respect to hospital admissions per year were as follows: 34.9% (37 patients) were never admitted, 26.4% (28 patients) were admitted fewer than 2 times, 24.5% (26 patients) were admitted 3–5 times, and 13.2% (14 patients) were admitted more than 5 times. The number of complications was used to measure the severity of the disease. The disease severity was higher in males than in females (67.3% vs. 32.7%, respectively;
P
= 0.018). The disease severity was higher in those who were born in the Western and Southwestern areas than in other areas (84.2% vs. 15.8%, respectively;
P
= 0.007). Hydroxyurea significantly reduced the severity of SCA with a
P
= 0.002.
Conclusion:
Our study showed that vaso-occlusive crisis was the most common complication and indication for hospital admission. Treatment with hydroxyurea led to a significant reduction in the number of hospital admissions.

April-June 2018, 9(2):59-62
DOI
:10.4103/joah.joah_1_18
BACKGROUND:
Premarital screening (PMS) is a mandatory laboratory examination before marriage to identify genetic blood and some infectious diseases. Sickle cell anemia (SCA) and thalassemia are genetic disorders caused by errors in the hemoglobin genes and are prevalent in Saudi Arabia
OBJECTIVE:
This study assessed the knowledge and response of the Al-Madinah community regarding PMS program.
METHODOLOGY:
This cross-sectional study assessed the knowledge and attitude of Al-Madinah community regarding hereditary blood disorders. Thirty-seven interviewers conducted direct and electronic interviews from October 2016 to January 2017.
RESULTS:
The total number of respondents was 2554, among the participants, 61% noted that PMS can diagnose SCA, 5.3% noted that PMS cannot diagnose SCA, and 33.4% answered “I don't know.” Regarding thalassemia, 50.2% answered that PMS can diagnose thalassemia, 7.4% answered “no,” and 42% answered “I don't know.” Furthermore, 76.4% of the participants answered that PMS can prevent SCA, whereas 71% of the participants answered that PMS can prevent thalassemia. Approximately 88.6% of the participants agreed to undergo elective PMS, 78.2% of them will not marry someone who has SCA or thalassemia, and 79.5% of them will not marry someone with a genetic trait if they themselves have a trait. In terms of raising the community's awareness on various hereditary blood disorders, 95.9%, 93.9%, and 92.5% agreed on the importance of media, medical education in school, and seminars, respectively.
CONCLUSION:
As half of the population were unaware about the screened diseases, it is necessary to raise the community's awareness on the importance of PMS.

Esraa Abu-Douleh, Nouf Al-Numair, Abdulmajeed Albanyan, Ayman Alsuliman, Nirvana Bayoumi, Tarek Owaidah
October-December 2018, 9(4):136-139
DOI
:10.4103/joah.joah_63_18
BACKGROUND:
von Willebrand disease (vWD) is the most common hereditary bleeding disorder, affecting up to 1% of the general population.
OBJECTIVES:
Estimating the prevalence of vWD among adolescents.
DESIGN:
This study was conducted between February 2014 and January 2016 on Saudi students in Riyadh.
SETTINGS:
We conducted an epidemiological survey on university students, using the standardized questionnaire based on molecular and clinical markers for the diagnosis and management of type 1 VWD.
MATERIALS AND METHODS:
All blood samples were tested for complete blood count, prothrombin time, partial thromboplastin time (PTT), and platelet function analyzer (PFA-100).
MAIN OUTCOME MEASURES:
Samples had an abnormal result of PTT and/or PFA-100 were tested for von Willebrand factor (vWF) antigen and factor VIII (FVIII) activity.
SAMPLE SIZE:
2000 university students aged between 17 and 22 years were included.
RESULTS:
Of these students, 730 (36.5%) had reported bleeding symptoms, 326 (44.6%) had agreed to give blood samples, 116 (35.5%) samples had prolonged PTT (>41 s), 48 (14.7%) had prolonged PFA-100 adenosine diphosphate, 39 (11.9%) had prolonged PFA-100 epinephrine, and 72 (22.0%) had abnormal results in both PTT and PFA-100. Out of 275 samples tested for vWF (Ag and activity) and FVIII, 13 (3.9%) had reduced levels or nonfunction of vWF and 5 (1.6%) had reduced FVIII levels. After correlation with ABO blood group, only 5 (1.6%) cases were confirmed for vWD. The prevalence of vWD among Saudi adolescents in the selected student population was 1.5%.
CONCLUSION:
In this study, we report for the first time epidemiological survey of bleeding disorders in Arab ethnicity.
LIMITATIONS:
As this is a prevalence study, we have no limitations to discuss.

January-March 2014, 5(1):15-18
DOI
:10.4103/1658-5127.131820
Background and Objective:
Recently totally implanted vascular access devices (TIVADs) have played an essential role in the management of pediatric patients. The purpose of this study was to describe the indications, techniques and complications of the procedures.
Design and Setting:
A retrospective study of all patients' files underwent TIVADs procedures between 2009-2012, in a single service providing institute in Saudi Arabia (King Saud Medical city-Riyadh).
Patients and Methods:
Fifty four TIVADs were inserted in fifty one patients (thirty males and twenty one females). Age ranged six months and twelve years (average 5.6 years). All TIVADs were implanted by pediatric consultant surgeons under general anesthesia. Seldinger technique used in fifty procedures and open approach in four patients.
Results:
The main indications for TIVADs use were acute lymphocytic leukemia forty six (90%), congenital nephrotic syndrum two (4%), hemophilia two (4%) and solid tumor one (2%). TIVADs were in situe for a total of 35222 days (average 652 days/catheter). Over all complications rate was (30%).
Conclusion:
TIVADs provided a simple almost pain free venous system access, allow children to conduct a normal life style and sport activities. We believe this study is one of very few reviews originating from developing countries with results comparable to those of world literature.

Muneer Al Bagshi, Al Omran Sadek, El Solh Hassan, Al Abaad Abbas
July-September 2013, 4(3):100-103
DOI
:10.4103/1658-5127.123304
Background:
Tumor lysis syndrome (TLS) comprises a number of metabolic and renal abnormalities of variable spectrum. It is associated with lymphoproliferative disorder e.g., acute lymphoblastic leukemia (ALL), non-Hodgkin lymphoma (NHL). The aim of this study to evaluate the incidence, severity and outcome in Saudi children with ALL.
Methods:
Medical records of Children age <14 years and diagnosed with ALL were reviewed. We adopted the Hande and Garrow definitions for tumor lysis Syndrome. All patients received hydration, alkalinization with sodium bicarbonate and allopurinol as prophylaxis.
Results:
Seventy-four patients developed TLS (19% of all patients). Boys were affected than girls with ratio of 2.4:1. LTLS occurred in 93.3% and CTLS in 6.7%. Hyperphosphatemia was found in 94.6% of the patients. Hyperkalemia occurred only in 17 patients (23%). Hypokalemia was found in significant number of patients (12%). Lymphomatous presentation was seen in 60 patients (82%). Hemodialysis was required in 5 patients (6.6%) and 4 of them had hyperleukocytosis. There were no deaths encounterd due to TLS. Male sex, lymphomatous presentation, high LDH, high pretreatment WBC and central nervous system involvement were found to have statistical significance as risk factors for TLS development.
Conclusion:
TLS is a common event in childhood ALL. Spontaneous TLS indicate highly proliferating tumor and possible delayed presentation to our institute. Prophylactic measures are important to improve the outcome particularly when initiated as soon as the diagnosis is established.

Is secondary hemophagocytic lymphohistiocytosis behind the high fatality rate in Middle East respiratory syndrome corona virus?
Ali Al-Ahmari
January-March 2015, 6(1):1-5
DOI
:10.4103/1658-5127.155168
Middle East respiratory syndrome corona virus (MERS-CoV) is becoming a major health concern in Saudi Arabia resulting in an associated high case fatality. The rapid deterioration of vital organs functions and high mortality rate seen in MERS-CoV has been observed previously in Epstein-Barr virus (EBV), severe acute respiratory syndrome caused by a coronavirus (SARS-CoV) and avian and bird flu-related hemophagocytic lymphohistiocytosis (HLH). There are many reports of successful treatments for severe cases of EBV-HLH using HLH-94/2004-type immunochemotherapy with etoposide as a pro-apoptotic agent. The use of immunochemotherapy in severe MERS-CoV-related HLH merits an urgent investigation in a well-designed clinical trial.

Clinical features and outcome of acute myeloid leukemia, a single institution experience in Saudi Arabia
Ahmed Al Faleh, Abdullah Al-Quozi, Ahmed Alaskar, Mohsen Al Zahrani
January-March 2015, 6(1):6-12
DOI
:10.4103/1658-5127.155171
Aim:
Acute myeloid leukemia (AML) is a type of malignancy that is associated with a malignant alteration of normal hematopoietic stem cells in the bone marrow. The aim of this study was to study the demographics and pathological subtypes of AML, evaluate the response and outcome to different treatment modalities.
Methods:
This was a retrospective study of adult patients diagnosed with AML at King Abdulaziz Medical City - Riyadh, between 2006 and 2013. Data were retrieved from patients' files, electronic medical files and laboratory information system.
Results:
91 patients were included in the study with a male dominance. M1 was the most common French-American-British subtype with 23 (32%) cases. Patients with intermediate-risk AML were the most common subgroup with 41 (48%) cases followed by high and low-risk subgroups, 29 (33%) and 16 (19%), respectively. 74 patients were treated with intensive chemotherapy, and 17 were on palliative chemotherapy or best supportive treatment. Remission rate was found to be 84% in patients who received induction chemotherapy while 41% of them relapsed. 93% of low-risk patients underwent complete remission (CR) compared to intermediate and high-risk patients (79% and 87% respectively), but it was not statistically significant (
P
= 0.4). The median follow-up was 19 months, with overall survival (OS) of 46% for all groups. The low-risk patients had the highest OS 57% compared to intermediate and high risk (52% and 36%, respectively), but it was not statistically significant (
P
= 0.3). 18 patients had been treated with allogeneic stem cell transplant and at a median follow-up of 17 months posttransplant the OS was 72%.
Conclusion:
This study shows M1 subtype to be the most common of AML in this population. In addition, the CR was better with similar survival rate as compared to other local and internationally published experiences. These results, albeit with its limitations, need to be confirmed in a prospective clinical trial or national disease registry.

Severe aplastic anemia (SAA) is a serious bone marrow disease that needs a comprehensive and service-intense treatment with either bone marrow transplantation (BMT) or immunosuppressive therapy (IST); both are difficult to optimally offer in resources-limited countries. Here, we report the outcome of IST using horse Antithymocyte globulin (ATG) in 18 (7 children; 11 adults) patients with SAA referred to our center in west India. Only 18 patients out of 102 diagnosed as AA in 2 years could receive IST, largely due to costs restraints. Although CR was seen in 30% in adults and 33% in pediatric cases, but overall 50% cases were able to enjoy transfusion-independence, requiring no further treatment. Treatment related mortality occurred in 6.2%, relapse in 6.2% and 6.2% had clonal evolution. This makes IST a valuable option for managing SAA in absence of bone marrow transplantation.
