Background:
Hemoglobinopathies as a group is one of the most common conditions confirmed through the newborn screening (NBS) program of the Philippines. This led to the increased participation of pediatric hematologists in the NBS program.
Objective:
The aim of the study was to assess newborn screening acceptance and knowledge of pediatric hematologists using an online questionnaire.
Method:
Members of the Philippine Society of Pediatric Hematology (PSPH), who are practicing pediatric hematologists in the Philippines, were invited to answer an online questionnaire.
Results:
Sixty members of the PSPH (65.2%) answered the survey. All the respondents are familiar with the newborn screening program. Fifty-seven respondents (95 %) have already managed a case of hemoglobinopathy identified through the newborn screening program. Differences in the approach to management and level of confidence with diagnostic test result interpretation have been noted. General themes of their concerns include being unaware of the protocol, concerns on delays in confirmatory tests, request for guidelines on follow-up, and incongruence of results with clinical picture.
Conclusion
The information collected may be used to develop strategies to better equip our pediatric hematologists and assist the PSPH standardize management protocols for hemoglobinopathies.

3.CASE REPORT - Type 2 Diabetes Mellitus with HbJ trait: A management conundrum

Optimal glycaemic control is crucial in patients with diabetes mellitus (DM) to avoid episodes of hypoglycaemia and both micro- and macrovascular complications. Diabetic control relies mainly on the evaluation of haemoglobin A1c (HbA1c), which is unfortunately unreliable in patients with haemoglobinopathies. This case report describes a patient with type 2 DM and haemoglobin J (HbJ) trait, which resulted in erratic HbA1c values throughout her follow-up. Other approaches, such as self-blood glucose monitoring, are needed to evaluate glycaemic control instead of relying on HbA1c alone to guide the management DM in these patients.

Hemoglobinopathy poses many challenges to the anesthesiologists. The central issue is the accuracy about interpretation of pulse oximetry saturation value during anesthesia. There are limited data with respect to the correlation between pulse oximetry saturation and oxygen saturation by arterial blood gas analysis in different hemoglobinopathies. We report here a case of a patient with hemoglobinopathy undergoing general anesthesia. Before the induction of anesthesia, various fractions of inspired oxygen were administered with concomitant measurement of oxygen saturation by pulse oximetry and arterial blood gas analysis. The saturation value by pulse oximetry, together with arterial blood gas analysis for oxygen tension, was used for evaluation of the patient's oxygenation status and speculation of the patient's oxygen saturation curve during the anesthesia.

Salmonella osteomyelitis is uncommon and it often develops in patients with sickle cell anemia and other hemoglobinopathy. Especially, osteomyelitis caused Salmonella typhi in a nonsickle cell patients is a very rare event. We report three cases with review of literature.

OBJECTIVE:
To explore the abnormal hemoglobinopathy in couples of child-bearing age in Chongqing.
METHODS:
A total of 34 800 subjects of child-bearing age were screened for thalassemia by using capillary electrophoresis from January 2015 to September 2018. PCR-flow cytometry fluorescence hybridization assay was used to detect the common thalassemia gene deletions and mutations.
RESULTS:
8 kinds of abnormal hemoglobinopathy were detected in 200 cases from 34 800 subjects of child-bearing age, the detection rate was 0.57% in couples of child-bearing age in Chongqing: Among 200 cases of abnormal hemoglobin pathy, Hb E was found in 90 cases (accounting for 45.0%), and Hb D in 25 cases (accounting for 12.5%). Hb NewYork was found in 25 cases (accounting for 12.5%). HbJ-bangkok was found in 25 cases (accounting for 12.5%), and Hb Q-Thailand in 16 cases (accounting for 8.0%). Hb Hope was detected in 15 cases (accounting for 7.5%). Hb S was detected in 3 cases (accounting for 1.5%). Hb Hasharon was detected in 1 case (accounting for 0.5%). The mean corpuscular volume (MCV) and mean corpuscular hemoglobin (MCH) of Hb E and Hb Q-Thailand were lower than normal reference intervals.
CONCLUSION
The detection rate of abnormal hemoglobinopathy in Chongqing is higher than the average level in China. Capillary electrophoresis can effectively screen abnormal hemoglobinopathy, which is great significant for aristogenesis and improvement of population quality.

Introduction:
Thalassemias and hemoglobinopathies are autosomal-recessive red blood cell disorders affecting
hemoglobin (Hb) quantity and/or quality. Clinical manifestations vary from clinically asymptomatic to transfusion dependent individuals. These disorders are global in scope and is prevalent in Southeast Asia hence screening in the Philippines is very crucial for its prevention and control.
Objective:
Our retrospective study aimed to determine the frequency of thalassemias and hemoglobinopathies in patients referred to the Molecular Genetics Unit, Institute of Human Genetics, National Institutes of Health, University of the Philippines, Manila for High Performance Liquid Chromatography (HPLC) screening.
Methods:
Blood samples from patients (n=622) sent by hematologists from different parts of the country from October 2008 to February 2015 were analyzed. Extracted whole blood samples from the subjects were anticoagulated with ethylenediaminetetraacetic acid (EDTA) and were analyzed using BIORAD VARIANT™ HPLC Testing System and VARIANT™ Beta Thalassemia Short (BTS) Program kit for the detection of abnormalities in hemoglobin. Interpretation of results were based on the submitted mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) values, and Hb typing via HPLC of the patients.
Results:
Approximately twenty-nine percent (29.10%, n=181) of subjects were presumptively identified with thalassemias and hemoglobinopathies by HPLC. Beta-thalassemia trait, Hb E trait, and beta-thalassemia/Hb E disease were detected in 65 (10.45 %), 14 (2.25 %), and 3 (0.48 %) subjects, respectively. While suspected alpha-thalassemia, presumably Hb H disease, was found in 99 (15.92 %) patients. Interestingly, seventy-two percent (72.11%, n=318) of the patients with normal Hb typing via HPLC have low MCV and MCH values.
Conclusion
Results of this study provide the spectrum and frequency of thalassemias and hemoglobinopathies in patients referred to our laboratory for HPLC analysis.
