RESUMEN
The study aimed to evaluate the validity and significance of Nacked Eye Single Tube Red cell Osmotic Fragility Test [NESTROFT] for screening of beta thalassaemia trait [BTT] to reduce the incidence of birth of thalassaemic child in community. Cross sectional study. This study was conducted at Diagnostic and Research Lab in Pathology Department of Peoples University of Medical Health Sciences [PUMHSW] at Shaheed Benazirabad from January 2013 to December, 2013. Total 504 subjects comprising 303 [60.3%] females and 201[39.7%] males with age ranging between 5 and 48 years and male to female ratio 1:1.5 were selected for this study. The family history of thalassaemia and history of cousin marriages were noted. EDTA anti-coagulated whole blood samples were collected for on-site NESTROFT testing, and later tested for Complete Blood Count [CBC] and serum Ferritin concentration at Diagnostic and Research Laboratory of Pathology Deptt. PUMHS. Screening for BTT was done on Naked Eye Single Tube Red cell Osmotic Fragility Test [NESTROFT] with 0.36% freshly prepared saline. The diagnosis of BTT was confirmed on automated Hemoglobin Electrophoresis at cellulose acetate alkaline pH. Red cell indices [automated Hematology cell counter cell-tac alpha] were assessed along with peripheral smear morphology [Leishman's stained slides] as enhanced tool for BTT case finding. Out of total 504 subjects 201 married women and 101 married men with their mean age [26.5 +/- 21.5] years were selected. In this study, female to male ratio was 1.5:1 and among the total 302 married subjects, ratio of cousin marriages [60.4%] was noted. Neither any women were pregnant nor there was history of thalassaemia in their families. The laboratory parameters such as the mean values of hemoglobin g/dl. RBC count millions/cmm, PCV%, MCV fl, MCH pg, MCHC g/dI among these subjects respectively were 11.9 g/dl, 4.5 millions/cram, 82 fi, 38.7%, 26.9 pg, 33.2 g/dl. Out of 504 samples, NESTROFT was positive in 21[4.1%] and negative in 483 [95.9%]. Out of all NESTROFT positive cases 15 [71.4%] were true positive confirmed on the hemoglobin electrophoresis with increased hemoglobin A2 level above 3.5 and remaining 6[28.6%] were false positive. Only 4 [1%] cases were false negative, then sensitivity, specificity, positive and negative predictive values and efficiency of NESTROFT were calculated 87%, 86%, 71%, 99% and 99.9 respectively. The NESTROFT is a valuable, cost effective screening test for beta thalassaemia trait
RESUMEN
This study was aimed to see the significance of Lactoferrin in human breast milk among lactating mothers of healthy and sick babies. This study was conducted at pathology and paediatrics departments of Peoples University of Medical and Health Sciences Nawabshan, Shaheed Benazirabad between Jan 2011 to Dec 2011. Cross sectional study. Lactoferin levels in breast milk of 356 mothers of healthy babies were estimated and similarly lactoferrin levels in breast milk of 318 lactating mothers of sick babies were estimated and these results were analyzed. The mean lectoferrin level in breast milk of 356 lactating mothers of healthy babies was 9.37 mg/ml and the mean lactoferrin level in breast milk of 318 mothers nursing sick babies was 3.73 mg/ml. There is decrease in lactoferrin levels of lactating mothers of sick babies in their mature milk, which could account for the susceptibility of their babies to infection
