Anemia among Pregnant Women at Nepalgunj Medical College

Introduction: Anemia in pregnancy is major health issue of developing countries responsible for adverse maternal and fetal outcome. According to World health organization pregnant women with hemoglobin level less than 11 gm/dl in first trimester and less than 10.5gm/dl in second and third trimester are considered to be anemic. Iron deficiency anemia is common during pregnancy followed by megaloblastic anemia. Aims: To find out the prevalence of anemia during pregnancy. To correlate the maternal and fetal complications associated with anemia during pregnancy. Methods: This is a prospective hospital based study done at department of obstetrics and gynecology Nepalgunj Medical College from July 2020 to January 2021. All pregnant women with hemoglobin level <11 gm/dl were enrolled in the study. Data were collected from antenatal clinic and biochemistry laboratory. Results: In this study maximum participants were of age group 20-25 consisting of 38.5%. Anemia was more common in multiparous i.e. 60% as compared to primipara i.e. 40%. In this study maximum participant had vaginal delivery (57%) followed by LSCS (29%) then instrumental delivery (14%). These ladies had complications like postpartum hemorrhage (27.7%), preterm labor (16.9%), pregnancy induced hypertension (9.2%). similarly 10.8% had sepsis and 20% had no complications. About 23.1% babies delivered by anemic ladies required neonatal intensive care. Intrauterine growth restriction was seen in 12.3%, preterm birth in 10.3% and 53.8% babies had no complications. Conclusion: The prevalence of anemia during pregnancy is high leading to adverse maternal and fetal outcome.

CUBN gene mutations may cause focal segmental glomerulosclerosis (FSGS) in children

Background Imerslund-Gräsbeck Syndrome (IGS) is mainly caused by CUBN gene biallelic mutations. Proteinuria accompanies IGS specific symptoms in about half of the patients, isolated proteinuria is rarely reported. Here we present 3 patients with isolated proteinuria and focal segmental glomerulosclerosis (FSGS) caused by CUBN gene biallelic pathogenic variants. Method Whole exome sequencing was performed on three children with isolated proteinuria. CUBN gene biallelic pathogenic variants were found and then verified by sanger sequencing. Their clinical, pathological and molecular genetic characteristics were analyzed and correlated accordingly. Results All three children presented with isolated proteinuria, no megaloblastic anemia. Their urine levels of β2 microglobulin were normal or slightly higher. Renal biopsies showed focal segmental glomerulosclerosis with mild glomerular mesangial hypercellularity, partial effacement of foot processes and podocyte microvillation. Two of them were found to carry compound heterozygous mutations and one homozygous mutation of CUBN gene. Totally four CUBN gene biallelic pathogenic variants were identified, including c.9287 T > C (p.L3096P), c.122 + 1G > A, c.7906C > T (p.R2636*), c.10233G > A (p.W3411*). Except for intron splice-site mutation, all other variants are located in highly conserved sites of CUB domain for binding to albumin. Conclusion The results demonstrate that CUBN gene mutations may cause isolated proteinuria pathologically presented as FSGS. Our cases extend the spectrum of renal manifestation and genotype of CUBN gene mutations.

Touchable cell biophysics property recognition platforms enable multifunctional blood smart health care

As a crucial biophysical property, red blood cell (RBC) deformability is pathologically altered in numerous disease states, and biochemical and structural changes occur over time in stored samples of otherwise normal RBCs. However, there is still a gap in applying it further to point-of-care blood devices due to the large external equipment (high-resolution microscope and microfluidic pump), associated operational difficulties, and professional analysis. Herein, we revolutionarily propose a smart optofluidic system to provide a differential diagnosis for blood testing via precise cell biophysics property recognition both mechanically and morphologically. Deformation of the RBC population is caused by pressing the hydrogel via an integrated mechanical transfer device. The biophysical properties of the cell population are obtained by the designed smartphone algorithm. Artificial intelligence-based modeling of cell biophysics properties related to blood diseases and quality was developed for online testing. We currently achieve 100% diagnostic accuracy for five typical clinical blood diseases (90 megaloblastic anemia, 78 myelofibrosis, 84 iron deficiency anemia, 48 thrombotic thrombocytopenic purpura, and 48 thalassemias) via real-world prospective implementation; furthermore, personalized blood quality (for transfusion in cardiac surgery) monitoring is achieved with an accuracy of 96.9%. This work suggests a potential basis for next-generation blood smart health care devices.

Severe megaloblastic anemia in twin pregnancy mimicking partial hemolysis, elevated liver enzymes and low platelet count syndrome: a case report

Vitamin B12 is well known cause of megaloblastic anemia. However, it is uncommon in pregnancy, occurs in 10-28% of uncomplicated pregnancies, and is associated with few complications. Present case of 32 years old woman with twin-pregnancy at late gestation who was diagnosed with severe anemia in a local private clinic. On arrival to medical center, lab findings together with her clinical picture warranted the concern for differential diagnosis of partial hemolysis, elevated liver enzymes and low platelet count (HELLP), but later it was found to be a case of vitamin B12 deficiency since additional lab findings. Blood transfusions were given, and patient responded well to B12 supplementation. Pregnancy was carried to term and delivered twin live babies but otherwise well at birth and had normal developmental milestones thereafter. Our case emphasizes the importance of screening for B12 deficiency in pregnancy, especially in at-risk women (twin-pregnancy in pure vegetarian women) with unexplained anemia/r thrombocytopenia.

Vitamin B12 Deficiency Resembling Acute Leukemia: A Case Report

Vitamin B12 deficiency in children can cause megaloblastic anemia, poor growth, and increased chances of infections. It is an important reversible cause of bone marrow suppression which at the time of presentation can mimic hematological malignancy. Therefore, it should be considered as a differential diagnosis in cases suspected of acute leukemia. We report a case of 14 months old child who had atypical presentation of vitamin B12 deficiency. He had chronic fever, decreased feeding and increased paleness for one year. Pancytopenia with severe anemia was present along with 19% reactive/atypical cells in peripheral blood smear suggesting acute leukemia. However, bone marrow aspiration and biopsy showed features of megaloblastic anemia. Vitamin B12 level measured was very low and treatment with cyanocobalamin caused drastic improvement in the child’s condition.
