Higher prevalence of poor prognostic markers at a younger age in adult patients with myelodysplastic syndrome - evaluation of a large cohort in India.

BACKGROUND: The karyotype is a major determinant of prognosis in myelodysplastic syndrome (MDS). Details of the cytogenetic profile of MDS in South Asia are limited because cytogenetic services are not widely available. METHODS: We performed a retrospective analysis of the cytogenetic and clinicopathologic profile of adult primary MDS seen consecutively at a tertiary-care centre in South India between 2003 and 2017. Patients were re-categorised according to the 2022 World Health Organisation (WHO) and the International Consensus classifications (ICC). RESULTS: There were 936 patients aged 18-86 years (median age 53, 65% males), with MDS with del 5q, low blasts and increased blasts in 7.5%, 58.4% and 34.1% respectively. Clonal abnormalities were seen in 55% of patients, with solitary abnormalities in 29.8% and complex karyotypes (CK, ≥ 3 abnormalities) in 15%. The most frequent abnormalities were monosomy 7/deletion 7q (16.1%), deletion 5q (14.5%), trisomy 8 (11.5%), and deletion 20q (5.1%). Cytogenetic prognosis groups were distributed as follows: very good, 2%; good, 55.6%; intermediate, 16.2%; poor, 15%; very poor, 11.2%. Clinical (IPSS-R) risk stratification (842 patients) showed: very low-risk, 3.9%; low-risk, 30.9%; intermediate-risk, 24.2%; high-risk, 21%; very high-risk, 20%. Age-adjustment (IPSS-RA) raised the very low-risk group to 12.4%; the other groups decreased by 1-3% each. CONCLUSION: The most significant finding of this cytogenetic analysis of MDS in India is that abnormal karyotypes with poor prognosis markers including monosomy 7 and CK were more frequent than in most other reports, among patients who were overall younger. Trisomy 8, deletion 20q, the IPSS-R intermediate-risk and both high-risk groups were more common than in the West. Trisomy 8 was less common than in South-East Asia while CK and deletion 20q were comparable. Evaluation of such large cohorts highlights the unique features of MDS in different parts of the world. These findings suggest that there could be differences in predisposing factors, environmental or genetic, and emphasise the need for further exploration to better understand the varied nature of MDS.

Imbalance in the vWF - ADAMTS13 axis exists early in acute pancreatitis and predicts persistent organ failure and pancreatic necrosis-a prospective study.

BACKGROUND: The pathophysiology of Acute Pancreatitis (AP) may be complicated by endothelial activation. von Willebrand Factor (vWF)- ADAMTS13 axis is a marker of endothelial activation. The study aimed to investigate the axis in AP, comparing it in patients with and without persistent organ failure (OF), with and without pancreatic necrosis, and correlating it with the standard severity scores (CRP, APACHE II, BISAP, SOFA, and qSOFA) METHODS: vWF-Antigen (vWF:Ag), vWF-Collagen-Binding-Assay (vWF:CBA), and ADAMTS13 activity (ADAMTS13:act) levels were measured within 5 days of symptom onset in consecutive patients (n = 98), who were admitted with a first episode of AP (Dec 2021-May 2023). RESULTS: Of the 98 patients admitted with AP, 78(79.6 %) had no or transient OF; 20(20.4 %) had persistent OF. Age was comparable (43.73 ± 15.36 vs 38.65 ± 13.69) [mean ± SD](years), and males were predominant in both groups (70.5 % vs 80 %). Patientswith persistent OF had higher vWF:CBA(%)[323(279-486.5) vs 199.5(159.1-295.75)] and lower ADAMTS13:act(%)[35.4(23.8-56.85) vs 56.35(44.1-71.9)][median (25th - 75th percentile)](P = 0.001) than those with no or transient OF. Patients with pancreatic necrosis (n = 19) had lower ADAMTS13:act(%)[42.79 ± 18.69] than those without pancreatic necrosis (n = 18) [62.49 ± 22.64] (P < 0.01). ADAMTS13:act had a negative correlation(r = -0.2), whereas vWF:Ag and vWF:CBA had a positive correlation (r = 0.2) with the standard severity scores (P < 0.05). ADAMTS13:act could predict pancreatic necrosis [AUROC-0.737, P < 0.05] and persistent OF [AUROC-0.746, P < 0.001], while vWF:CBA could predict persistent OF [AUROC- 0.73, P < 0.001]. CONCLUSION: vWF-ADAMTS13 axis helps to predict severe disease and is associated with poor outcomes in acute pancreatitis.

On-treatment decline in MELD score predicts one-month transplant-free survival in rodenticidal hepatotoxicity patients treated with low-volume plasma exchange.

BACKGROUND AND AIM: Plasma exchange (PLEX) improves survival in patients with rodenticidal hepatotoxicity. However, predictors of treatment response are unknown. We aimed at assessing predictors of response to PLEX treatment in these patients. METHODS: Patients with rodenticidal hepatotoxicity from 2014 to 2023 managed in our department were included in this study. Kochi criteria (model for end-stage liver disease [MELD] score ≥ 36 or international normalized ratio [INR] ≥ 6 with hepatic encephalopathy [HE]) derived specifically for rodenticidal hepatotoxicity (PubMed IDentifier [PMID]: 26310868) were used to assess need for liver transplantation. We analyzed predictors of survival at one month. ∆Bilirubin, ∆MELD score and ∆INR were calculated as percentage change of the parameter after third PLEX session (or after last PLEX if < 3 PLEX sessions done) from baseline pre-PLEX value. RESULTS: Of 200 patients with rodenticidal hepatotoxicity, 114 patients were treated with low-volume PLEX (PLEX-LV). No patient had liver transplantation. Of 78 patients who fulfilled Kochi criteria, 32 patients were PLEX-LV eligible and underwent PLEX-LV (M: 10; age: 20.5, 7-70 years; median, range; acute liver failure: 24). Twenty-two (69%; acute liver failure: 14) of the 32 patients were alive at one month. Presence of HE (p = 0.03) and ∆MELD (p < 0.001) were significant predictors on univariate analysis, while ∆MELD (aOR = 0.88, 95% CI: 0.79-0.98, p = 0.01) was the only significant independent predictor of one-month transplant-free survival. Area under receiver operating characteristic (ROC) for ∆MELD was 0.93 (95% CI:0.85-1.00) and a decrease of ≥ 20% in MELD score while on PLEX-LV had 90% sensitivity and 90% specificity in predicting one-month survival. CONCLUSIONS: Decline in MELD while on PLEX-LV independently predicted one-month transplant-free survival in rodenticidal hepatotoxicity patients. This may help guide decision on stopping PLEX-LV in patients predicted to respond to treatment and to consider alternate treatment options in non-responders.

Centrifugal technique of plasma exchange and low-dose steroid to treat very severe alcoholic hepatitis patients: A retrospective analysis.

BACKGROUND: Low-volume plasma exchange (PLEX) and low-dose steroid improve survival in severe alcoholic hepatitis. We aimed to compare one-year survival of very severe alcoholic hepatitis (VSAH) patients treated with centrifugal PLEX (cPLEX), membrane PLEX (mPLEX) or standard medical treatment (SMT). METHODS: We retrospectively analyzed survival in consecutive VSAH patients treated at our department from November 2017 to September 2021. PLEX patients received low-volume PLEX along with low-dose steroid (tab. prednisolone 10 mg or 20 mg daily). To adjust for baseline differences between the three treatment (cPLEX, mPLEX or SMT) groups, propensity score (PS) matching was done. Acute-on-chronic liver failure (ACLF) was defined as per European Association for the Study of the Liver (EASL). The primary study outcome was one-year transplant-free survival of PS-matched VSAH patients treated with cPLEX compared to SMT. RESULTS: Of 101 PLEX-eligible VSAH patients, 30 patients were treated with cPLEX, 21 with mPLEX and 50 with SMT. On comparing 30 PS-matched patients each in the cPLEX group vs. the SMT group, transplant-free survival in the cPLEX group was 86.7% at one month, 70% at three months and 52.4% at one year and in the SMT group was 33.3% at one month, 23.3% at three months and 16.7% at one year with hazard ratio (HR [95% CI]) in favor of the cPLEX group (0.29 [0.15-0.56], p < 0.001). Total 21 patients each (PS-matched) in cPLEX and mPLEX groups were compared and one-year survival was better with cPLEX (0.33 [0.16-0.69], p = 0.001). The sub-group analysis of VSAH (PS-matched cohort) patients with ACLF also showed better survival with cPLEX compared to SMT (0.38 [0.17-0.83], p = 0.003) and compared to mPLEX (0.43 [0.17-0.95], p = 0.03). CONCLUSION: Better one-year transplant-free survival was noted among PS-matched VSAH patients treated with cPLEX (and low-dose steroid) compared to SMT (without steroid).

Biomarkers of coagulation, endothelial, platelet function, and fibrinolysis in patients with COVID-19: a prospective study.

Prospective and sequential evaluation of homeostatic changes leading to thrombosis across COVID 19 disease severity spectrum are limited. In this prospective observational study, haemostasis was evaluated in patients with mild, moderate-severe, and critical COVID-19 infection. Markers of endothelial activation [Soluble thrombomodulin (sTM), von Willebrand Factor (VWF)], platelet activation [Soluble P-selectin, beta-thromboglobulin (BTG)] and global haemostasis [Rotational thromboelastometry (ROTEM)] were evaluated on days 1 and 5 after admission. The study cohort comprised of 100 adult patients (mild = 20, moderate-severe = 22, critical = 58). Sixty-five patients received anticoagulation for 10 (7-14) days. Thrombotic events were seen in 9 patients. In-hospital mortality was 21%. Endothelial activation markers were elevated at baseline in all subgroups, with levels in moderate-severe (sTM = 4.92 ng/ml, VWF = 295 U/dl) [reference-ranges: sTM = 2.26-4.55 ng/ml; Soluble P-selectin = 13.5-31.5 ng/ml; BTG = 0.034-1.99 ng/ml] and critical patients (sTM = 6.07 ng/ml, VWF = 294 U/dl) being significantly higher than in the mild group (sTM = 4.18 ng/ml, VWF = 206 U/dl). In contrast, platelet activation markers were elevated only in critically ill patients at baseline (Soluble P-selectin = 37.3 ng/ml, BTG = 2.51 ng/ml). The critical group had significantly lower fibrinolysis on days 1 and 5 when compared with the moderate-severe arm. COVID-19 infection was associated with graded endothelial activation and lower fibrinolysis that correlated with illness severity.

Focused panel sequencing points to genetic predisposition in non-cirrhotic intrahepatic portal hypertension patients in India.

OBJECTIVE: Non-cirrhotic intrahepatic portal hypertension (NCIPH), a portal microangiopathy affecting small portal vein radicles, is a disease of Indian sub-continent. NCIPH appears to be a complex disease with interactions between inherited and acquired factors, though the exact pathophysiological mechanism is unknown. We aimed at investigating the genetic variants that might contribute to susceptibility to NCIPH. METHODS: In this case-control study, we analyzed genes associated with microangiopathy-VWF-ADAMTS13 (von Willebrand factor and its cleavase enzyme - a disintegrin and matrix metalloprotease with thrombospondin type-1 motifs member 13) and alternative complement system vitamin B12 metabolism and with familial NCIPH. RESULT: Eighty-four Indian patients with liver biopsy-proven NCIPH (cases) and 103 healthy controls (matched for residential region of India) were included in the study. Targeted next-generation sequencing (NGS) panel, comprising 11 genes of interest, was done on 54 cases. Genotyping of selected variants was performed in 84 cases and 103 healthy controls. We identified variants in MBL2, CD46 and VWF genes either associated or predisposing to NCIPH. We also identified a single case with a novel compound heterozygous mutation in MBL2 gene, possibly contributing to development of NCIPH. CONCLUSION: In this first of a kind comprehensive gene panel study, multiple variants of significance have been noted, especially in ADAMTS13-VWF and complement pathways in NCIPH patients in India. Functional significance of these variants needs to be further studied.

Cytogenetic profile of 1791 adult acute myeloid leukemia in India.

BACKGROUND: Cytogenetic analysis continues to have an important role in the management of acute myeloid leukemia (AML) because it is essential for prognostication. It is also necessary to diagnose specific categories of AML and to determine the most effective form of treatment. Reports from South Asia are few because the availability of cytogenetic services is relatively limited. METHODS: We performed a retrospective analysis of the cytogenetic findings in adults with AML seen consecutively in a single centre in India. The results were categorised according to the 2022 World Health Organisation (WHO), International Consensus Classification (ICC) and European LeukemiaNet (ELN) classifications. RESULTS: There were 1791 patients aged 18-85 years (median age 42, 1086 males). Normal karyotypes were seen in 646 (36%) patients. The 1145 (64%) abnormal karyotypes comprised 585 (32.7%) with recurrent genetic abnormalities (RGA), 403 (22.5%) with myelodysplasia-related cytogenetic abnormalities (MRC), and 157 (8.8%) with other abnormalities. There were 567 (31.7%) patients with solitary abnormalities and 299 (16.7%) with two abnormalities. Among the 279 (15.6%) patients with ≥ 3 abnormalities, 200 (11.2%) had complex karyotypes (CK) as per the WHO/ICC and 184 (10.3%), as per the ELN definition. There were 158 (8.8%) monosomal karyotypes (MK). Patients with normal karyotypes had a higher median age (45 years) than those with abnormal karyotypes (40 years, p < 0.001), and those with ≥ 3 abnormalities (43 years), than those with fewer abnormalities (39 years, p = 0.005). Patients with CK (WHO/ICC) and monosomal karyotypes had a median age of 48 years. Those with RGA had a lower median age (35 years, p < 0.001) than MRC (46 years) or other abnormalities (44 years). The t(15;17) was the most common abnormality (16.7%),followed by trisomy 8 (11.6%), monosomy 7/del 7q (9.3%), t(8;21) (7.2%), monosomy 5/del 5q (6.7%) and monosomy 17/del 17p (5.2%). CONCLUSION: Our findings confirm the lower age profile of AML in India and show similarities and differences with respect to the frequencies of individual abnormalities compared to the literature. The frequencies of the t(15;17), trisomy 8 and the high-risk abnormalities monosomy 7 and monosomy 5/del 5q were higher, and that of the inv(16), lower than in most reports.

Platelets provide robustness of spatial blood coagulation to the variation of initial conditions.

Activated platelets provide phospholipid surface and secrete coagulation factors, enhancing blood clotting. We investigated the role of platelets in the regulation of blood coagulation spatial dynamics. We activated blood clotting with tissue factor-bearing (TF) surface in platelet-rich plasma (PRP) or platelet-free plasma (PFP). When blood coagulation was initiated by high TF density, clot growth rate (V) in PRP (2 × 105/µL platelets) was only 15 % greater than in PFP. Spatial distribution of thrombin in PRP had a peak-like shape in the area of the fibrin clot edge, while in PFP thrombin was distributed in the shape of descending plateau. Platelet inhibition with prostaglandin E1 or cytochalasin D made spatial thrombin distribution look like in the case of PFP. Inhibition of blood coagulation by natural endogenous inhibitor heparin was diminished in PRP, while the effect of the exogenous or artificial inhibitors (rivaroxaban, nitrophorin, hirudin) remained undisturbed in the presence of platelets. Ten times decrease of the TF surface density greatly depressed blood coagulation in PFP. In PRP only clotting initiation phase was, while the propagation phase remained intact. Coagulation factor deficiency greatly reduced amount of thrombin and decreased V in PFP rather than in PPR. Thus, platelets were redundant for clotting in normal plasma under physiological conditions but provided robustness of the coagulation system to the changes in initial conditions.

Comparing two techniques of performing an epidural catheter-assisted epidural blood patch using a 20 ml syringe versus a 5 ml syringe and its effect on clotting time, the strength of clot retraction and haemolysis - A prospective in vitro study (EC-EBP study).

Background and Aims: Epidural blood patch (EBP) is performed by injecting autologous blood into the epidural space using a Tuohy needle. Certain clinical scenarios mandate an epidural catheter (EC)-assisted EBP. Collecting blood in a 20-ml versus 5-ml syringe appears to influence the quality of the clot. This in vitro study compared the techniques of performing the EC-assisted EBP using 20-ml versus 5-ml syringe on clotting time (CT), clot retraction (CR) and haemolysis. Methods: This in vitro study was performed in a haematology laboratory. Five consented adult healthy male volunteers donated blood. In the 5-ml syringe technique, blood was injected through an EC, and as it flowed out of the tip, it was collected at the beginning and the end of 1 min. With the 20-ml technique, blood was collected at the beginning and end of the first, second and third minute. The samples were tested for CT, CR and haemolysis by measuring the plasma-free haemoglobin (PFHb). Results: Five injections were made using a 5-ml syringe, and another five with a 20-ml syringe. Injection time was shorter in the 5-ml technique (80.80 ± 5.89 vs. 272 ± 28.4 s, P < 0.0001). With the 20-ml technique, CT progressively increased (>15 min), whereas, with the 5-ml syringe, the CT was normal. Both techniques caused mild, insignificant haemolysis (PFHb >0.005 g/dl), without affecting the quality of CR. Conclusion: EC-assisted EBP using a 5-ml syringe technique shortens the injection time and deposits fresh blood quickly without affecting CT and CR.

Utility of Cryohemolysis Test in the Diagnosis of Hereditary Spherocytosis.

Diagnosis of Hereditary spherocytosis (HS) often requires time-consuming and/or expensive tests. Cryohemolysis test (CHT) is a simple and easy to perform test with high predictive value for HS diagnosis. In this prospective study, we evaluated the diagnostic utility of CHT for the diagnosis of HS. We included 60 suspected HS patients, 18 patients with Autoimmune hemolytic anemia (AIHA) and 120 healthy controls. Among the 60 suspected cases, there were 36 HS cases and 24 with other hemolytic anemias. The mean CHT (%) ± SD for controls, AIHA, other hemolytic anemias, and HS was 6.63 ± 2.79, 6.79 ± 4.36, 6.61 ± 2.76 and 26.7 ± 8.9, respectively. The CHT % was significantly higher in HS group when compared to controls (p = < 0.0001), AIHA (p = < 0.0001) and other hemolytic anemia groups (p = < 0.0001). At a CHT cut off of > 18.3%, the sensitivity, specificity, positive predictive value and negative predictive value for diagnosis of HS in our study were 97.1%, 94.4%, 97.2% and 90.3%, respectively. CHT is a simple and sensitive test for the diagnosis of HS but remains underutilized. The addition of CHT in the diagnostic workup of HS will be very useful, especially in a resource limited setting.

Comparison of Point-of-Care PT-INR by Hand-Held Device with Conventional PT-INR Testing in Anti-phospholipid Antibody Syndrome Patients on Oral Anticoagulation.

Evidence on agreement of point-of-care (POC) INR testing with laboratory testing in APS patients on oral anticoagulation (OAC), is scarce. This study assessed agreement of paired PT INR testing by a POC device vs. conventional platform-based laboratory test, in APS patients on OAC using a pre-determined definition of agreement. Simultaneous paired PT INR estimation in 92 APS patients was carried out, during October 2020-September 2021. POC INR was performed on capillary blood (pin prick) using the qLabs® PT-INR hand-held device, while laboratory INR estimation was performed using citrated blood (venepuncture) on STA-R Max Analyzer® using STA-NeoPTimal thromboplastin reagent®. Concordance was defined no greater than ± 30% (as per international standards ISO 17593:2007 guidelines) for each paired INR estimation. Agreement between the two was defined as ≥ 90% of paired INR measurements being concordant. 211 paired estimations were performed, within which 190 (90%) were concordant. Good correlation was seen between the 2 methods of INR estimation on Bland Altman plot analysis with an Intra-class correlation coefficient (95% CI) of 0.91(0.882, 0.932). Lab INR range > 4 (P = 0.001) was a significant predictor of higher variability between both methods of INR estimation. Lupus anti-coagulant, other anti-phospholipid antibodies (APL) or triple APL positivity did not result in any statistically significant variation in paired measurements. This study demonstrated good correlation between POC INR measurement and Lab INR estimation and agreement was ascertained between the 2 methods in APS patients on OAC.

Randomized, Double-Blind, Active Comparator Pharmacodynamic Study of Platelet Inhibition with Crushed and Integral Formulations of Clopidogrel and Ticagrelor in Acute Coronary Syndrome.

BACKGROUND: Crushed formulations of specific antiplatelet agents produce earlier and stronger platelet inhibition. We studied the platelet inhibitory effect of crushed clopidogrel in patients with acute coronary syndrome (ACS) and its relative efficacy compared with integral clopidogrel, crushed and integral ticagrelor. OBJECTIVES: We aimed to compare the platelet inhibitory effect of crushed and integral formulations of clopidogrel and ticagrelor in patients with acute coronary syndrome (ACS). METHODS: Overall, 142 patients with suspected ACS were randomly assigned to receive crushed or integral formulations of clopidogrel or ticagrelor. Platelet inhibition at baseline and 1 and 8 h was assessed using the VerifyNow assay. High on-treatment platelet reactivity (HTPR) ≥ 235 P2Y12 reaction units (PRUs) 1 h after the medication loading dose was also determined. RESULTS: The PRU and percentage inhibition median (interquartile range) at 1 h for the different formulations were as follows: crushed clopidogrel: 196.50 (155.50, 246.50), 9.36 (- 1.79, 25.10); integral clopidogrel: 189.50 (159.00, 214.00), 2.32 (- 2.67, 19.89); crushed ticagrelor: 59.00 (10.00, 96.00), 75.53 (49.12, 95.18); and integral ticagrelor: 126.50 (50.00, 168.00), 40.56 (25.59, 78.69). There was no significant difference in PRU or percentage platelet inhibition between the crushed and integral formulations of clopidogrel (p = 0.990, p = 0.479); both formulations of ticagrelor were superior to the clopidogrel formulations (p < 0.05). On paired comparison, crushed ticagrelor showed robust early inhibition of platelets compared with the integral formulation (p = 0.03). Crushed clopidogrel exhibited the maximal HTPR of 34.3%, but was < 3% for both formulations of ticagrelor. CONCLUSIONS: The platelet inhibitory effect of crushed clopidogrel is not superior to integral preparation in patients with ACS. Crushed ticagrelor produced maximal platelet inhibition acutely. HTPR rates in ACS are similar and very low with both formulations of ticagrelor, and maximal with crushed clopidogrel. Clinical Trials Registry of India identifier number CTRI/2020/06/025647.

Overall equipment effectiveness, efficiency and slide review analysis of high-end hematology analyzers.

This study evaluated and compared the overall equipment effectiveness (OEE), sensitivity, specificity, and efficiency of the high-end hematology analyzers, Yumizen H2500, DxH 800, DxH 900 and XN-9000 (XN-10). A total of 400 anonymized left over's K2 EDTA whole blood samples were analyzed for complete blood count. Of 400 samples, 200 were tested on Yumizen H2500; DxH 800 & DxH 900 while the other 200 were tested on Yumizen H2500 & XN-9000 (XN-10), respectively. The OEE was good and comparable for all the hematology analyzers except DxH 800 showing an average status. The sensitivity (%), specificity (%) and turnaround time (in minutes) for Yumizen H2500, DxH 800, DxH 900 and XN-9000 (XN-10) were 91.67, 61.11 & 103; 66.67, 54.55, & 149; 83.33, 27.27 & 136; 83.33, 28.57 & 122, respectively. Confusion matrix highlights the difficulty for DxH 800 and DxH 900 to discriminate left shift or blasts with large hyper-segmented neutrophils. The flags triggered by Yumizen H2500 were markedly changed to large hyper-segmented neutrophils. Lymphoblast caused more confusion for XN-9000 (XN-10), as it came out to be atypical lymphocytes, or hypersegmented neutrophils. Although comparable in OEE index to other analyzers, the Yumizen H2500 seems to be more reliable in detecting the abnormal cells as it has high sensitivity, specificity and less turnaround time. Thus, analysis adding specificity, sensitivity, and efficiency parameters to the OEE index provides more reliable information of the analyzers.

Low Volume Plasma Exchange and Low Dose Steroid Improve Survival in Patients With Alcohol-Related Acute on Chronic Liver Failure and Severe Alcoholic Hepatitis - Preliminary Experience.

Background: Alcohol-related acute on chronic liver failure (A-ACLF) patients have high short-term mortality and are poor candidates for steroid therapy. Plasma exchange (PLEX) improves survival in ACLF patients. We analyzed our experience with low volume PLEX (50% of plasma volume exchanged per session) and low dose steroids to treat A-ACLF patients. Methods: We retrospectively compared the efficacy of low volume PLEX and low-dose steroids with standard medical treatment (SMT) in A-ACLF patients treated at our center between November 2017 to June 2019. The primary study outcome was one-year survival. Results: Twenty-one A-ACLF patients in PLEX group [age 40 (29-56) years, median (range); MELD score 31 (29-46)] and 29 A-ACLF patients in SMT group [age 41.5 (28-63) years, MELD score 37 (21-48)] were studied. All 50 study patients had severe alcoholic hepatitis [mDF 84.7 (50-389)]. PLEX group patients had 3 (1-7) PLEX sessions with 1.5 (1.4-1.6) liters of plasma exchanged per session and oral Prednisolone 20 mg daily, tapered over 1 month. Kaplan Meier analysis showed better survival over 1 year in the PLEX group compared to the SMT group (P = 0.03). There was renal dysfunction in 10 patients in the PLEX group, which normalized in six patients after PLEX. Conclusion: In this preliminary report, compared to SMT, low volume PLEX and low dose steroid improved survival over one year in A-ACLF patients with severe alcoholic hepatitis. In patients with renal dysfunction, 60% showed improvement in renal function with PLEX. Studies with a larger number of patients are needed to validate these results.

Utility of International Society on Thrombosis and Hemostasis Bleeding Assessment Tool (ISTH-BAT) in Patients with Inherited Bleeding Disorders: A Cross-Sectional Study from Southern India.

The International Society on Thrombosis and Hemostasis bleeding assessment tool (ISTH-BAT) was developed to record bleeding symptoms and aid in patient diagnosis. This study was done to investigate the utility of ISTH-BAT in patients suspected to have inherited bleeding disorders. This cross-sectional study was conducted in a tertiary care hospital in Southern India over 3 and 1/2 years. A trained investigator administered the ISTH-BAT questionnaire to 432 patients undergoing evaluation for inherited bleeding disorder prior to routine coagulation screening and confirmatory tests and to 131 healthy volunteers as controls. Among patients, 42(9.7%) had primary hemostatic defect, 150(34.7%) had secondary hemostatic defects and 229(53%) had normal screening coagulogram with mean bleeding scores (BS) being 5.9, 6.9, and 4.2 respectively and the proportion of patients with abnormal BS being 69%, 88.7% and 59.4% respectively; the latter qualifying as unknown hemostatic defect. 11(2.5%) with acquired hemostatic defect on workup were excluded. The mean BS was 1.52 among healthy volunteers. Common bleeding patterns were epistaxis (73.8%), cutaneous bleeding (52.4%), hematuria (54.8%), menorrhagia (50%) in primary hemostatic defect; cutaneous bleeding (72%), muscle hematoma (58.7%), hemarthrosis (46.7%), menorrhagia (58.7%) in secondary hemostatic defects and epistaxis (45.9%), cutaneous bleeding (62.4%), menorrhagia (30.7%) in normal screening coagulogram group. Grade of bleeding was mostly 2 and sometimes 4 in primary, 2-4 in secondary and 1-2 in normal screening coagulogram group. ISTH-BAT is a valuable tool to record lifelong bleeding history. The pattern and score give clues regarding the nature and severity of the bleeding disorder.
