One slide from each of these 94 cases was stained with GATA3 and STAT6 independently and pattern of staining (either nuclear or cytoplasmic or dual nuclear and cytoplasmic) was accessed. </p> <p><strong>Results: </strong>75/79(95%) cases of CHL were positive for GATA3 staining [60/79(75.9%) cases showed nuclear GATA3 staining, 15/79(18.9%) cases showed both nuclear and cytoplasmic staining] and 4/79(5%) CHL cases were negative for GATA3. 15/15(100%) cases of NLPHL were negative for GATA3[12/15(80%) cases showed no staining and 3/15(20%) cases showed only cytoplasmic blush]. 65/79(82%) cases of CHL were positive for STAT6[17/79(21.5%) cases showed nuclear STAT6 expression, 48/79(60.7%) cases showed both nuclear and cytoplasmic staining], and 14/79(18%) cases of CHL were negative for STAT6 expression [8/79(10%) cases showed only cytoplasmic staining and 6/79(8%) showed neither nuclear nor cytoplasmic staining]. 14/15(93.3%) cases of NLPHL were negative for STAT6[5/79(33.3%) cases showed only cytoplasmic staining and 9/15(60%) cases showed no staining] and 1/15(6.7%) case of NLPHL was positive for STAT6[showed nuclear STAT6 staining].</p> <p><strong>Conclusion: </strong>Nuclear staining of GATA3 and STAT6 either alone or in combination with cytoplasmic staining can be used to differentiate CHL from NLPHL. GATA3 effectively excludes NLPHL with 100% negative predictive value.</p> <p><strong>Keywords: </strong>GATA3, STAT6, Classic Hodgkin lymphoma, Nodular lymphocyte predominant Hodgkin lymphoma</p> Nida Babar, Sajid Mushtaq, Mohammad Tariq Mahmood, Asad Hayat Ahmed, Mudassar Hussain , Usman Hassan Copyright (c) 2023 Pakistan Journal of Pathology https://creativecommons.org/licenses/by-nc/4.0 https://pakjpath.com/index.php/Pak-J-Pathol/article/view/774 Thu, 21 Sep 2023 00:00:00 +0000 COMPARISON OF POINT-OF-CARE HEMOGLOBIN A1C TESTING WITH CENTRAL LABORATORY METHOD FOR ITS USE IN SCREENING AND MONITORING OF DIABETES MELLITUS IN A RESOURCE-CONSTRAINED SETTING https://pakjpath.com/index.php/Pak-J-Pathol/article/view/788 <p><strong>Objective: </strong>The aim of this study is to evaluate the analytical performance of the Point-Of-Care Testing HbA1c analyzer for its use as an alternate to the central/core laboratory method. </p> <p><strong>Material and Methods: </strong>This was a cross-sectional study in which 176 samples of HbA1c were analyzed by POCT HbA1c analyzer (A1C EZ 2.0) and central laboratory analyzer (Cobas 6000) as comparative instrument.</p> <p><strong>Results:</strong> Based on the Bland-Altman plot, the HbA1c level for 164 out of 176 (93.18%) subjects analyzed by the POCT-HbA1c was within the range of the 95% limit of agreement. The area under the receiver operating characteristic (ROC) curve for clinical diagnosis of diabetes was 0.91. The sensitivity and specificity for HbA1c POCT were 94.5% and 88.0%. <strong> </strong>Using regression analysis, the slope of the A1C EZ 2.0 vs the Cobas 6000 Analyzer was 0.934, with an intercept of 0.20 and a correlation coefficient of 0.97.</p> <p><strong>Conclusion:</strong> This study concludes that the POCT-HbA1c analyzer is a suitable replacement for central/core laboratory HbA1c measurement. It is useful for screening and monitoring of diabetes mellitus in certain situations especially in a resource constraint setting.</p> <p><strong>Keywords: </strong>Diabetes mellitus, Screening, Monitoring, HbA1c, Point-of-care testing</p> Sara Reza, Hafiz Muhammad Salman Yousaf, Lubna Sarfraz, Adil Mehmood Copyright (c) 2023 Pakistan Journal of Pathology https://creativecommons.org/licenses/by-nc/4.0 https://pakjpath.com/index.php/Pak-J-Pathol/article/view/788 Thu, 28 Sep 2023 00:00:00 +0000 SERUM ACTIVIN A & INHIBIN A: POSSIBLE BIOCHEMICAL MARKERS OF PREECLAMPSIA & PREGNANCY INDUCED HYPERTENSION https://pakjpath.com/index.php/Pak-J-Pathol/article/view/763 <p><strong>Objective:</strong> The objective of this study was to compare the levels of Serum Activin A and Inhibin A in Pregnancy induced hypertension, Preeclampsia &amp; Normal Pregnancy</p> <p><strong>Material and Methods: </strong>An analytical, cross-sectional study conducted at Chemical Pathology Laboratory Collaborating with Gynae/Obstetric Department of Pakistan Railway Teaching Hospital, Rawalpindi over the period of one year (18 Sep 2019 to 18 March 2020). The study started after the approval of Ethical Review Committee, Riphah International University Islamabad. The sample size was calculated using WHO sample size calculator. Taking Prevalence of PIH and PE is 8%.<sup>3</sup> Non probability convenient sampling technique was used. An overall 100 pregnant women with gestation of 20 – 25 weeks, were included. Patients of UTI, Carcinomas, Diabetes Mellitus and other chronic disorders were not included. The subjects were divided into three groups. Group I PIH: This group included 30 pregnant women of PIH; 20 - 25 weeks of gestation, BP: ≥140/90 mmHg on two separate occasions without proteinuria. Group II PE: This group included 20 pregnant women of preeclampsia; 20 - 25 weeks of gestation, BP: ≥140/90 mmHg on two separate occasions with proteinuria (&gt;0.3 g protein/24 hours Urine). Group III Control Group: This group included 50 pregnant women with gestational age of 20 – 25 weeks without any complication as healthy controls.</p> <p><strong>Results: </strong>It was determined that Serum Activin A and Serum Inhibin A levels were significantly increased in PIH and PE groups as compared to healthy group. Mean of Serum Activin A in PIH, PE and Control group was (251.53<u>+</u>200.23 pg/ml), (466.95 <u>+</u> 237.40 pg/ml) and (43.35 <u>+</u> 85.22 pg/ml) respectively. Similarly Mean and Standard Deviation of Serum Inhibin A levels in PIH, PE and Control group was (194.78 <u>+</u> 173.00 pg/ml), (349.20 <u>+</u> 190.30 pg/ml) and (17.27 <u>+</u> 44.33 pg/ml) respectively. One-way ANOVA and post-hoc Tukey analysis was conducted to compare the mean of Serum Activin A and Serum Inhibin A levels among three different groups i.e Group 1(PIH and PE), Group 2(PIH and Control) and Group 3 (PE and Control). p-value&lt; 0.05 was considered as statistically significant.</p> <p><strong>Conclusion: </strong>It can be concluded that Serum Activin A and Serum Inhibin A can be used as biochemical markers of PIH and PE. Estimation of Serum Activin A and Inhibin A at an early stage can detect PIH and PE early and further prevents their complications such as Eclampsia and HELLP syndrome.</p> <p><strong>Keywords:</strong> Pregnancy induced hypertension (PIH), Pre-eclampsia (PE), HELLP syndrome (H – Hemolysis, EL- Elevated Liver Enzymes, LP – Low platelets count), Serum activin A, Serum inhibin A.</p> Ammar Hassan, Muhammad Nadeem Akbar Khan, Saadia Sultana, Rubina Shafi, Siyab Ahmed, Fakhra Noureen Copyright (c) 2023 Pakistan Journal of Pathology https://creativecommons.org/licenses/by-nc/4.0 https://pakjpath.com/index.php/Pak-J-Pathol/article/view/763 Thu, 21 Sep 2023 00:00:00 +0000 REFERENCE RANGE OF NT PRO BNP IN HEALTHY PREGNANT FEMALES https://pakjpath.com/index.php/Pak-J-Pathol/article/view/769 <p><strong>Objective: </strong>To define the Reference Range of NT pro-BNP (N-terminal pro–B-type natriuretic peptide) during the first trimester of pregnancy in healthy females.</p> <p><strong>Material and Methods:</strong> This Cross-sectional study was conducted in the Department of Chemical Pathology, Combined Military Hospital, Lahore from September to November 2022. This cross-sectional study focused on the reference range of NT pro-BNP in healthy pregnant females. Sampling of the data was done by using the nonprobability consecutive sampling technique. A maximum number of available participants (365 pregnant females) during the study period were recruited. Descriptive statistics were shown as mean ±SD. For the reference range for NT pro-BNP 2.5<sup>th</sup> percentiles (lower limit) and 97.5<sup>th</sup> percentiles (upper limit) were estimated.</p> <p><strong>Results: </strong>A total of 365 pregnant females were included with first trimester pregnancy, having the mean age 28.54±5.18 years. Out of 365 participants, 299 females had BMI &lt;25 whereas 66 were overweight. Forty-One females had Hb level ≤ 10 g/dl and 324 females had HB &gt;10 g/dl. The Platelet count was &gt;150 x 10^9/L in 338 women, and ≤150 x 10^9/L in 26 women. The Median of NT pro-BNP was 56.80 pg/mL in the first trimester. Reference range of NT pro-BNP in pregnant women with BMI &lt;25 was (17.89 – 257.00) pg/mL as compared to (16.88 – 130.63) pg/mL in those with BMI &gt;25.</p> <p><strong>Conclusion: </strong>The Reference range of NT pro-BNP changes in pregnancy as compared to healthy non-pregnant adults, likely due to hemodynamic changes associated with pregnancy. This study has defined a Pregnancy-specific reference range of NT pro-BNP in the first trimester which can help diagnose pregnant women with underlying cardiovascular disease.</p> <p><strong>Keywords: </strong>NT pro-BNP, Reference range, Pregnancy</p> Mariam Saeed, Muhammad Zeeshan Rana, Najeebullah Khan, Hina Anwar, Shakeel Ahmed Copyright (c) 2023 Pakistan Journal of Pathology https://creativecommons.org/licenses/by-nc/4.0 https://pakjpath.com/index.php/Pak-J-Pathol/article/view/769 Thu, 21 Sep 2023 00:00:00 +0000 CORRELATION OF DEMOGRAPHIC VARIABLES AND CLINICAL FINDINGS WITH CHEMICAL BIOMARKERS IN TYPE 1 DIABETES https://pakjpath.com/index.php/Pak-J-Pathol/article/view/767 <p><strong>Objective:</strong> To find correlation between different demographic variables and chemical markers in Type 1 Diabetes so that disease can be picked up at an early stage if individuals are categorized properly.</p> <p><strong>Material and Methods:</strong> It was a cross sectional analytical study conducted at Chughtai Institute of Pathology, from April 2021 to March 2022.
