Status of Serum Ferritin Level among Iron Deficiency Anemic Adolescent Girls in Bangladesh.

Adolescence explained as a period of age between 10 to 19 years. This is a major contributing period to build up the health of girls. Ferritin is an intracellular protein that contains iron and releases it in a controlled fashion and it reflects body iron stores and systemic inflammation during adolescent period. It is considered the best single test for the diagnosis of iron deficiency anemia during adolescent because its concentration is directly proportional to total body iron stores in adolescent period. This study was done in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh to evaluate the changes of serum ferritin levels among iron deficient anemic adolescent girls in comparison to healthy adolescent girls in Bangladesh. This was a cross sectional, prospective, analytical type of study. This study ranged from 10-19 years of adolescent girls. Seventy (70) healthy adolescent girls, as control group (Group I). Seventy (70) iron deficiency anemic adolescent girls as study group (Group II). Serum ferritin was estimated by Micro-particle Enzyme Immunoassay Test Kit. Data were expressed as mean (±SD). Statistical significance of difference among the Group I and Group II were calculated by unpaired students 't' test. The mean±SD level of serum ferritin among Group I and Group II were 26.22±4.03µg/L and 13.33±3.18µg/L respectively. Mean values ±SD of serum ferritin significantly lower in (Group II) in comparison with (Group I). Higher numbers of adolescent girls are still suffering from anemia along with low level of serum ferritin in Bangladesh. For combat this situation, immediate, sustainable and long term public health intervention and nutritional supplementation must be required.

Relation of Serum Iron Level with Serum Zinc Level among Adolescent Girls with Iron Deficiency Anaemia in Bangladesh.

Adolescent girls are vulnerable in underdeveloped and developing countries due to having public health problems regarding iron deficiency anaemia. As zinc acts as a cofactor in iron metabolism, so the deficiency of this trace element is associated with iron deficiency anaemia. This study was done to evaluate the changes of serum iron and serum zinc levels among iron deficient anaemic adolescent girls in comparison to healthy adolescent girls in Bangladesh. This prospective type of analytical cross sectional study was carried out in the Department of Physiology, Mymensingh Medical College, Mymensingh, Bangladesh from July 2019 to December 2020. Total number of 140 adolescent girl's age ranged from10-19 years included in this study. Among them, 70 healthy adolescent girls, were taken as control group (Group I). Remaining 70 Adolescent girls with iron deficiency anaemia (IDA) were taken as study group (Group II). Estimation of serum iron was determined by Ferrozine method using Globals iron kit, UK. Serum zinc levels were determined by colorimetric method with reagents. All data were expressed as mean (±SD) and statistical significance of difference among the group I ( healthy adolescent girls) and group II (adolescent girls with iron deficiency anaemia) were calculated by unpaired students' 't' test. Correlation of serum iron with serum zinc was done by Pearson's correlation coefficient test. The mean values (±SD) of serum iron level of Group I and Group II were 69.06±18.11µg/dl & 15.61±9.12µg/dl respectively. Mean values (±SD) of serum iron significantly lower in study group (Group II) in comparison with control group (Group I). The mean (±SD) of serum zinc level of Group I and Group II were 75.48±14.26µg/dl & 33.27±12.94µg/dl respectively. Mean value (±SD) of serum zinc levels were significantly lower in study group (Group II) in comparison with control group (Group I). Serum zinc level was positively correlated with serum iron and that was statistically significant. The deficiency of iron does not occur alone; rather it is typically associated and developed with hypozincemia. The study suggests on supplementing iron along with zinc to correct the deficiency especially in adolescent girls when their metabolic demand is high.

Diversity of Vibrio parahaemolyticus in marine fishes of Bangladesh.

AIMS: To determine the occurrence, diversity, antibiotic resistance and biofilm formation of Vibrio parahaemolyticus isolated from marine fishes in Bangladesh. METHODS AND RESULTS: A total of 80 marine fishes were obtained from the local markets and examined for the presence of V. parahaemolyticus. All the isolated V. parahaemolyticus were characterized for the presence of virulence markers, thermostable direct hemolysin (TDH) or thermostable direct hemolysin related hemolysin (TRH). Isolates were serotyped and further characterized by enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) typing to analyse the genetic diversity. Moreover, biofilm formation and antibiotic resistance patterns were also determined. About 63·75% (51/80) of the tested marine fishes were contaminated with V. parahaemolyticus. From the contaminated fishes, 71 representatives V. parahaemolyticus were isolated and none of them harboured tdh and trh virulence genes. Nine different O-groups and seven different K-types were found by serological analysis and the dominant serotype was O5:KUT. In ERIC-PCR analysis, eight clusters (A-H) were found and the most common pattern was A (46·5%). All of the isolates were resistant to ampicillin and 78·9% of isolates were resistant to streptomycin. The highest biofilm formation was found at 37°C compared to 25°C and 4°C. CONCLUSION: Diverse V. parahaemolyticus are present in marine fishes in the local market of Bangladesh with antibiotic-resistant properties and biofilm formation capacity. SIGNIFICANCE AND IMPACT OF THE STUDY: The widespread prevalence of diverse V. parahaemolyticus in marine fishes is an issue of serious concern, and it entails careful monitoring to ascertain the safety of seafood consumers.
