Flow control by circular cavities in lateral flow porous membranes.

This research explores the flow penetration in porous media by virtue of capillary action and geometric control of the liquid imbibition rate in microfluidic paper-based analytical devices (µPADs) having applications in food quality management, medical diagnostics, and environmental monitoring. We examine changes in flow resistance and membrane geometry, aiming to understand factors influencing capillary penetration rates for various practical applications. We conducted experiments and simulations using lateral porous membranes and altered the flow resistance by changing the liquids or the paper channel geometry by adding cavities. From experiments, it was revealed that by creating a circular cavity in the paper channel, the penetration rate was sufficiently altered. Moreover, increasing the cavity size and type of liquid (w.r.t. viscosity) also caused a decrease in the flow rate. Imbibition rates were also influenced by the position of the cavities in the paper channel. The maximum delay for water was almost 2 times with a 16 mm circular cavity located at 3 cm from strip bottom edge. Overall, we attained a maximum delay in the case of castor oil which was almost 85 times slower than water and 3.7 times slower than olive oil. A good agreement was observed with CFD analysis. We believe that this research would help in developing advance techniques to enhance the flow control strategies in µPADs and indicators.

Burnout and Health Related Quality of Life among emergency physicians working at emergency at Tertiary Care Hospital in Lahore Pakistan.

Objective: To determine frequency of burnout in emergency physicians and to identify its impact on their health-related quality of life (HRQOL). Methods: In this cross-sectional study, physicians from departments with emergency cover of Jinnah Hospital Lahore were included. Their burnout and HRQOL scores using Maslach Burnout Inventory (MBI) and Short Form (SF)-36 respectively were determined in March 2022. Burnout scores were graded as low, moderate and high and were correlated with domains of HRQOL using chi X2 and analysis of variance (ANOVA). Results: One hundred fifty physicians were included with mean age 26.2 (±2.59), male to female ratio 0.78:1 (66/84) and House Officer (HO) to Postgraduate Resident (PGR) ratio 1.94:1 (99/51). High burnout was identified in 76 (50.7%) participants while 48 (32%) had moderate and 26 (17.3%) had low burnout. Males scored better than female physicians in vitality (0.008), general mental health (0.004), and mental component summary (0.01) domains of HRQOL. Doctors with high burnout had significantly lower scores in both physical component summary (p-value 0.004) and mental component summary (p-value < 0.0001) domains of HRQOL. Conclusion: Physicians working in emergency settings have high frequency of burnout and it adversely affects their mental and physical health related quality of life.

Predicting common bile duct stones: Comparison of SAGES, ASGE and ESGE criteria for accuracy.

Objective: To determine accuracy of SAGES, ASGE and ESGE criteria for predicting presence of common bile duct (CBD) stones. Methods: In a prospective study at Jinnah Hospital Lahore from March 2021 to February 2022, patients with suspected CBD stone were stratified in High risk (HR), intermediate risk (IR) and low risk (LR) for SAGES, ASGE and ESGE criteria. All patients underwent ERCP and risk strata were analyzed using SPSS 22® for sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. Results: In 90 patients with mean age 45.18(±14.87) and male/female ratio 0.64(35/55), area Under Curve (AUC) for predicting CBD stones was 0.75, 0.81and 0.83 for HR and 0.28, 0.52 and 0.52 for IR group while it was 0.53, 0.81 and 0.53 for absence of stone in LR group of SAGES, ASGE and ESGE criteria respectively. HR groups had accuracy of 81.1%, 86.7% and 87.8% in predicting CBD stone while LR criteria had 68.8%, 86.7% and 68.1% accuracy in predicting absence of CBD stone for SAGES, ASGE and ESGE respectively. Conclusion: HR strata of SAGES, ASGE and ESGE scores have excellent accuracy in predicting CBD stones whereas IR and LR criteria are suboptimal for excluding CBD stones.

Mortality in Patients of COVID-19 Infection: Biochemical Markers and its Cut-off Values for Predicting Outcome.

OBJECTIVE: To determine the efficacy and cut-off values of C-reactive protein (CRP), lactate dehydrogenase (LDH), serum ferritin, and D-dimer for predicting mortality of COVID-19 infection. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Department of Medicine, Jinnah Hospital, Lahore from January to May 2021. METHODOLOGY: Serum CRP, LDH, ferritin, and D-dimer were measured in patients with moderate to severe COVID-19 infection at admission. Patients were followed for in-hospital disease outcome. ROC curve was used to determine area under curve (AUC) and cut-off values of biomarkers, followed by multi-variate analysis by logistic regression. RESULTS: In 386 patients, male to female ratio was 1.47/1 (230/156); and mean age was 54.03 ± 16.2 years. Disease was fatal in 135 (35%) patients. AUC for mortality was 0.730 for LDH, 0.737 for CRP, 0.747 for ferritin and 0.758 for D-dimer. Mortality was higher with LDH ≥400 U/ml, Odds Ratio (OR) 5.37 (95% CI 3.01-9.57: p = 0.001), CRP ≥30 ng/L, OR 4.30 (95% CI 2.11-8.74: p = <0.001), serum ferritin ≥200 ng/ml, OR 4.13 (95% CI 1.05-16.2: p = 0.02), and D-dimer ≥400 ng/ml, OR 2.72 (95% CI 1.06-7.01: p = 0.03) with 2 log likelihood of 131.54 for predicting disease outcome with 71.7% accuracy in multi-variate analysis. CONCLUSION: Elevated serum CRP, LDH, ferritin and D-dimer are associated with higher mortality in patients of COVID-19 infection. Serum CRP ≥30ng/ml, LDH ≥400 U/L, ferritin ≥200 ng/ml and D-dimer ≥400 ng/ml can predict fatal outcome in COVID-19 patients. Key Words: C-reactive protein (CRP), COVID-19 infection, D-dimer, Ferritin, Lactate dehydrogenase (LDH), Mortality.

Risk of Covid-19 infection during endoscopy: Efficacy of personal protective equipment (PPE) in protecting health professionals.

OBJECTIVES: To correlate compliance to personal protective equipment (PPE) protocols and risk of exposure to SARS-COV-2 infection in endoscopy staff. METHODS: We included 85 endoscopic procedures performed at Lahore General Hospital from May to July 2020. Standard operating procedures (SOPs) were implemented for patient selection, risk stratification and personal protective equipment (PPE) use for endoscopy staff. Patient and endoscopy staff were followed for Covid-19 infection. PPE scores for staff and Covid-19 positivity on follow-up were correlated using student's t test. RESULTS: Following 85 procedures included, 2 (2.3%) patients became Covid-19 positive. PPE score was <9 in 5 (5.8%) procedures for endoscopist and Covid-19 developed in 2 (2.3%) of them, PPE score was <9 during 19 (22.3%) procedures in 1st assistant and 9 (10.5%) developed infection and for 2nd assistant PPE score was <9 in 19(22.3%) endoscopies and 5 (5.9%) tested positive for covid-19. Infectivity of endoscopy staff was 6.2%. Association between PPE score and risk of Covid-19 was not significant. (p value 0.51 for endoscopist, 0.10 for 1st assistant and 0.09 for 2nd assistant). CONCLUSION: Compliance of SOPs for infection control reduces risk of acquiring Covid-19 infection during endoscopy. Proper use of PPE is effective for safety of endoscopy staff.

Concomitant Therapy versus Triple Therapy: Efficacy in H. Pylori Eradication and Predictors of Treatment Failure.

OBJECTIVE: To compare concomitant therapy (CT) and triple therapy (TRT) for success in helicobacter (H.) pylori eradication and identify factors associated with treatment failure. STUDY DESIGN: Quasi-experimental comparative study. PLACE AND DURATION OF STUDY: Department of Medicine and Gastroenterology, Services Institute of Medical Sciences from December 2018 till July 2019. METHODOLOGY: Patients with H. pylori infection were randomly assigned to receive two weeks of either CT or TRT. H. pylori eradication was confirmed by repeat biopsy four weeks post-treatment. Treatment outcome was compared using Chi-square test, while binary logistic regression identified predictors of treatment failure. RESULTS: Two hundred and eleven patients with H. pylori infection, having mean age 40.15 (±13.04) and male/female ratio 0.9/1 (100/111) after randomisation, were treated with CT in 105 patients (49.8%) and TRT in 106 patients (50.2%). H. pylori was eradicated in 84.3% (150/178) patients with completed follow-up. H. pylori eradication was achieved in 91.9% of CT group as compared to 77.2% in TRT group (p = 0.007, OR 3.38: 95% CI 1.3-8.3). Age ≥40 years (p = 0.02), symptoms duration >6 months (p = 0.001), and prior proton pump inhibitor use for >4 weeks (p = 0.01), were identified as independent predictors of treatment failure. CONCLUSION: CT achieves better H. pylori eradication than TRT. Older age, longer duration of illness, and previous proton pump inhibitor use were independent predictors of H. pylori treatment failure. Key Words: Concomitant therapy, Eradication, H. pylori, Triple therapy.

Bed side teaching: Student's perception and its correlation with academic performance.

OBJECTIVE: To determine student's perception of bedside clinical teaching and to correlate it with their performance in assessment. METHODS: This cross-sectional study of correlational survey was conducted at Services Institute of Medical Sciences in September 2019, involving students of final professional year who filled a proforma to rate their bedside teaching experience during clinical rotations using rating scale. Mean scores of items were determined with score < 3 reflecting dis-satisfaction. Mean scores were compared between high and low performing students using student's t test. RESULTS: Total of 160 students participated. Physical environment domain was assigned lowest scores by students (mean 2.94±0.74) followed by teaching task by teachers (3.04±0.72), group dynamics (3.16±0.81) and patient comfort and attitude towards patient (3.87±0.60). Teaching task by teacher had maximum stems with scores < 3 needing significant improvement. Students with low academic performance were more unsatisfied with group dynamics of bedside teaching (p value 0.009), especially lack of equal opportunities of participation for every member (p value <0.000) in clinical rotations. CONCLUSION: Small size group with adequate space for bedside training and faculty training can enhance learning experience of students. Ensuring active participation of each group member during bedside learning can improve academic performance of students.

Post-ERCP Pancreatitis: Risk factors and role of NSAIDs in primary prophylaxis.

OBJECTIVE: To determine efficacy of diclofenac suppository in reducing post-ERCP pancreatitis (PEP) and identify risk factors for PEP. METHODS: This is a placebo-based prospective study at Department of Medicine & Gastroenterology, Services Institute of Medical Sciences / Services Hospital, Lahore performed from January 2018 to June 2019. Patients were randomized to receive diclofenac suppository or glycerine suppository before ERCP. Both groups were compared for PEP using chi square x2 test while risk factors for PEP were determined using binary logistic regression. RESULTS: Total of 165 patients with mean age 49.1(±15.2) and male to female ratio 1/1.6 (63/102) were included. Among 82 (49.7%) patients in diclofenac group, 8 (9.7%) developed pancreatitis while 19(22.9%) of 83(50.3%) in placebo group had PEP (p value 0.02). After multivariate analysis, age>45 years (p value 0.014, OR 3.2), Bilirubin >3 mg/dl (p value 0.004 OR 3.58), time to cannulation> 5 minutes (p value<0.000 OR 9.2), use of precut (p value< 0.000 OR 4.9), pancreatic duct cannulation (p value 0.000 OR 5.46) and total procedure time >30 minutes (p value 0.01 OR 3.92) were risk factors for PEP. CONCLUSION: Pre-procedure Diclofenac suppository reduces post-ERCP pancreatitis. Age > 45 years, serum bilirubin > 3 mg/dl, cannulation time > 5 minutes, use of precut, pancreatic duct cannulation and procedure time > 30 minutes are risk factors for post-ERCP pancreatitis.

Primary prophylaxis of hepatic encephalopathy in decompensated cirrhosis: Low dose vs. full dose rifaximin.

OBJECTIVE: To compare efficacy of high vs low dose rifaximin for primary prophylaxis of portosystemic encephalopathy (PSE) in decompensated liver cirrhosis. METHODS: In a quasi-experimental double blind randomized study at Services Institute of Medical Sciences (SIMS), Lahore from August 2017 to August 2018, patients of decompensated cirrhosis with no previous PSE were randomized to receive twice daily rifaximin 200mg in Group-A and 550mg in Group-B. Patients were followed for 6 months for development of PSE. RESULTS: In 75 included patients, mean age was 53.8(±10.7) years and male/female ratio was 0.97/1(37/38). After randomization, 34 (45.3%) patients were included in Group-A and 41 (54.7%) patients in Group-B. During 6 month follow up 24 (32%) patients developed PSE, 12 (35.2%) in Group-A and 12 (29.2%) in Group-B, difference was not significant (p value 0.57). In 6 months, 13 (17.3%) patient died, 6 (17.6%) in Group-A and 7 (17.07%) patients in Group-B, difference not significant (p value 0.94). Patients who died had higher bilirubin (p < 0.00), higher serum creatinine (p 0.05), high CTP score (p 0.04) and worse MELD score (p 0.004). CONCLUSION: Rifaximin is not effective for primary prophylaxis of overt hepatic encephalopathy in decompensated cirrhosis patients.

Effect of adding daclatasvir in sofosbuvir-based therapy in genotype 3 hepatitis C: real-world experience in Pakistan.

OBJECTIVE: To determine real-world effect of adding daclatasvir (DCV) to chronic hepatitis C treatment by comparing sustained viral response of sofosbuvir (SOF)/DCV±ribavirin (RBV) and SOF+RBV combination in patients with genotype 3 hepatitis C. PATIENTS AND METHODS: Patients with chronic hepatitis C, genotype 3, presenting at the DHMC Hepatology Clinic from October 2014 till March 2018 were treated initially with 6 months of SOF/RBV, and once DCV was available, with SOF/DCV±RBV for 3 or 6 months. Negative hepatitis C virus RNA by PCR, sustained viral response 12 weeks after treatment (SVR12), was the primary end point for per-protocol analysis. RESULTS: The mean age of the 440 enrolled patients was 51.04 (±11.9) years, and male to female ratio was 0.97/1 (217/223). Liver cirrhosis was present in 260 (59.1%) patients, and 89 (20.2%) had decompensated liver disease. Treatment-experienced patients were 124 (28.2%). We included 398 (90.4%) patients with completed follow-up in final analysis, excluding either dropped out, failed to complete therapy or died during follow-up. SVR12 was achieved in 366 (91.9%), being significantly lower (P=0.001) in patients with cirrhosis at 89.9% (205/228), and even lower SVR12 (P=0.006) in decompensated cirrhosis at 87.01% (67/77). SVR12 was also inferior (P=0.005) in treatment experienced patients at 85.8% (97/113) than treatment-naive patients at 94.3% (269/285). Among 285 patients treated with SOF/RBV, SVR12 was achieved in 264 (92.6%), which is not significantly different from SVR12 with SOF/DCV±RBV at 90.2% (102/113) (P=0.57). CONCLUSION: In patients with chronic hepatitis C genotype 3, SOF/RBV and SOF/DCV±RBV have similar sustained viral response, and patients with liver cirrhosis and past treatment experience have suboptimal response in Pakistan.

Cephalosporin resistance in community acquired spontaneous bacterial peritonitis.

OBJECTIVE: To determine 3rd generation cephalosporin resistance in patients with community-acquired spontaneous bacterial peritonitis (SBP) using early response assessment. METHODS: This prospective quasi-experimental study was carried out at Doctors Hospital & Medical Center from January 2016 to September 2018. Patients with cirrhosis and SBP were included. Third generation cephalosporins i.e. cefotaxime/ceftriaxone were used for treatment of SBP. Response after 48 hours was assessed and decline in ascitic fluid neutrophil count of < 25% of baseline was labelled as cephalosporin resistant. Carbapenem were used as second line treatment. Recovery and discharge or death of patients were primary end points. RESULTS: Male to female ratio in 31 patients of SBP was 1.2/1 (17/14). Hepato-renal syndrome was diagnosed in 11(37.9%) patients. Cefotaxime was used for 16(51.6%) patients whereas ceftriaxone for 15(48.3%) patients. Early response of SBP was noted in 26(83.8%) patients while 5 (16.2%) were non-responders to cephalosporins. SBP resolved in all non-responding patients with i/v carbapenem. In-hospital mortality was 12.9% and had no association with cephalosporin resistance. High bilirubin (p 0.04), deranged INR (p 0.008), low albumin (p 0.04), high Child Pugh (CTP) score (p 0.03) and MELD scores (p 0.009) were associated with in-hospital mortality. CONCLUSION: Cephalosporin resistance was present in 16.2% of study patients with community-acquired SBP. Mortality in SBP patients is associated with advanced stage of liver disease.

Health Related Quality of Life (HRQOL) and its correlation with academic performance of medical students.

OBJECTIVE: To determine health related quality of life (HRQOL) of medical students and its correlation with their academic performance. METHODS: Cross sectional study at Services Institute of Medical Sciences, included students of 4th and final year MBBS, who filled SF-36 proforma of HRQOL. Scores of 8-domains and of physical component and mental component summary were determined. Marks in all professional examinations were used to stratify students as high performers (≥ 70% marks) and average performing students (< 70%). HRQOL scores was correlated with academic performance using unpaired student's t-test. RESULTS: Among 267 students included, mental health score (56.2±21.3) was lower than physical health component score (69.03±18.5). Role limitation due to emotional health (RE) (44.81), Vitality (VT) (54.19) and general health perception (GH) (58.89) had lower scores among 8-domains of questionnaire. Female students had significantly lower scores in role limitation due to emotional problems (p value <0.04), vitality (<0.05), bodily pain (p value <0.05) and general health perception (p value<0.03) than male students. Physical health and role limitation due to physical health domains were better in high performing students. CONCLUSION: Mental health of medical students is suboptimal, especially among female students. Students with better physical health have better academic performance.

Sofosbuvir based therapy in hepatitis C patients with and without cirrhosis: Is there difference?

OBJECTIVE: To compare sustained viral response to sofosbuvir/ribavirin ±interferon therapy in patients of hepatitis C with and without liver cirrhosis. METHODS: This observational study of chronic hepatitis C patients was carried out at Doctors Hospital and Medical Center (DH&MC). After diagnostic workup, Sofosbuvir/ribavirin for 24 weeks or sofosbuvir/ribavirin/pegylated interferon for 12 weeks were prescribed. Primary outcome was negative HCV RNA by PCR 12 weeks after treatment completion (SVR12). Chi square χ2 and student's t test were used to analyze data. RESULTS: Of 216 patients included, liver cirrhosis was present in 112 (51.9%) patients and 69(31.9%) were treatment experienced. Liver disease was decompensated in 37 (17.1%) patients. Of 206 patient who completed study protocol, 173(83.1%) achieved SVR12, 89.2% (25/28) with triple therapy and 82.2% (148/180) with sofosbuvir/ribavirin therapy. Treatment response was similar between treatment naïve 86.2% (119/138) and treatment experienced 79.4% (54/68) patents. (p value 0.19) SVR12 was inferior in cirrhosis patients 75.4% (80/106) as compared to those with no cirrhosis 93% (93/100) (p value < 0.000). It was even lesser in those with decompensated liver disease 68.8% (24/35) (p value < 0.000). CONCLUSION: Treatment outcome with sofosbuvir/ribavirin combination therapy in cirrhosis patients is suboptimal especially in those with decompensation as compared to patients without liver cirrhosis.

Perception of educational environment: Does it impact academic performance of medical students?

OBJECTIVE: To compare environmental perception as measured by the Dundee Ready Educational Environment Measure of students with high and low academic performance. METHODS: This cross-sectional analytical study was carried out at the Gujranwala Medical College, Gujranwala, Pakistan, and comprised medical students. Dundee Ready Educational Environment Measure questionnaire with 50 items was used to determine students' perception of the institutional environment. Academic performance was based on mean percentage of marks obtained in all professional examinations. High achievers with 70% or more marks were compared with low achievers with <70% marks for Dundee Ready Educational Environment Measure scores using unpaired Student's t-test. RESULTS: Of the 180 students, 153(85%) were included. Of them, 35(22.87%) were boys and 118(77.12%) girls. The overall mean Dundee Ready Educational Environment Measure score was 116.13±18.24. As for the subscales, the mean score for 'perceptions of learning' was 27.97±6.0, 25.76±4.6 for 'perceptions of teachers', 18.67±4.05 for 'academic self-perceptions', 27.76±6.03 for perceptions of atmosphere and 15.97±3.0 for social self-perceptions. The mean dream score was 108.51±17.54 among boys and 118.39±17.90 among girls. The mean score for perception of having successful learning strategies was 1.66±0.9and 2.18±0.9 among low and high achievers (p>0.05) and 1.71±0.98 and 2.18±1.1 for ability to memorise all that was needed (p>0.05). CONCLUSIONS: Environmental perception of the institution was more positive than negative and better performance in examinations was associated with better academic self-perception and social self-perception in students.

Peer-Assisted Learning: Who Should Be the Tutor, Fellow Student or Senior Resident?

OBJECTIVE: To compare student-tutor guided peer-assisted learning (STPAL) and resident-tutor guided peer-assisted learning (RTPAL) for its impact on performance of students in summative assessment. STUDY DESIGN: Quasi-experimental study. PLACE AND DURATION OF STUDY: Gujranwala Medical College, from February to September 2015. METHODOLOGY: Four batches each of final year MBBS students were first trained for clinical skills by resident-tutors for 2 weeks and had a pre-test. Two students with highest marks were selected as student-tutors. Half of the batch had a further 2 weeks skill training by the student-tutors while other half by resident-tutor, post-test was carried out after 2 weeks. Improvement in scores was compared between STPAL and RTPAL groups, using unpaired student t-test. The batch underwent same intervention for the next month with cross-over of STPAL and RTPAL groups. RESULTS: Study population was 152 out of expected 188 as batch D underwent the study only once and 13 students were either absent or had decline in scores, so were excluded. Among 74 (48.68%) STPALand 78 (51.23%) RTPAL students, median improvement in scores was 8 for STPAL group as compared to 7 for RTPALgroup; the difference was not statistically significant (p= 0.61). CONCLUSION: Student-tutor guided peer-assisted learning is as effective as resident-tutor peer assisted learning in improving performance of the students.

Association Between Functional Dyspepsia and Severity of Depression.

OBJECTIVE: To determine the association between functional dyspepsia and the severity of depression. STUDY DESIGN: Cross-sectional study. PLACE AND DURATION OF STUDY: Department of Medicine, King Edward Medical University/Mayo Hospital, Lahore, from September 2012 till January 2013. METHODOLOGY: After taking informed written consent, patients with symptoms of dyspepsia fulfilling the Rome III criteria were included in the study. All patients were evaluated for depression, using Hamilton depression rating scale (HDRS). Upper gastrointestinal endoscopy was done. Fischers' exact test and independent t-test were used for determining significance of association. RESULTS: One hundred and one patients with mean age of 35.81 (±14.81) years and male to female ratio of 1.41:1 (54/47) were included. Predominant symptoms were early satiety (72.3%), epigastric pain (65.3%), bloating (49.5%), postprandial fullness (40.6%), and regurgitation (40.6%). Alarm symptoms were positive in 44 (43.6%) patients. Dyspepsia were classified as epigastric pain syndrome (EPS, 69.3%), and postprandial distress syndrome (PDS, 30.7%). Significantly more females had PDS (p=0.04), with positive endoscopic findings in EPS (p=0.03). Positive endoscopic findings noted were esophagitis in 21.8%, and gastritis in 48.5% patients. All patients except one had depression, mild in 22.8%, moderate in 33.7%, severe in 31.7%, and very severe in 10.9% patients. Severe depression was seen in 32 (45.7%) patients with EPS and PDS; whereas very severe depression was in 11 (15.7%) patients of EPS, while 11 (35.4%) patients of PDS had severe depression but the difference was not significant. CONCLUSION: Functional dyspepsia is associated with depression, while positive endoscopic findings are more likely in patients with EPS. Very severe depression was only seen with epigastric pain syndrome.

Hepatorenal syndrome:Response to terlipressin and albumin and its determinants.

OBJECTIVE: To determine the efficacy of terlipressin and albumin in improving renal functions in patient with hepatorenal syndrome (HRS) and to identify factors determinant of better response. METHODS: In this quasi experimental interventional study patients of liver cirrhosis and ascites with HRS type I were treated with intravenous albumin and incremental dosage of terlipressin based on response with maximum dose of 12mg/day. Decline of creatinine below 1.5mg/dl was defined as complete response. Factors predictive of response to therapy were determined via linear regression analysis. RESULTS: Twenty four patients were included with male to female ratio 3.8/1(19/5) and mean age 53.3 (±10.06). Complete response to terlipressin/albumin was seen in 14 (58.3%)patients, seven (29.2%) achieved partial response with > 25% creatinine decline while three (12.5%) had no response. Lower serum creatinine at diagnosis (P value 0.003), absence of hyperkalemia (p value 0.005) and absence of portal vein thrombosis (p value 0.05) are associated with response to treatment in HRS. Baseline serum creatinine (p value 0.003) was independent predictor of response to therapy in multivariate analysis. CONCLUSION: Terlipressin and albumin is an effective treatment for HRS type I. Patients with lower baseline serum creatinine are more likely to respond to this therapy.

Response Guided Interferon Therapy for Genotype 3 of Chronic Hepatitis C: Compliance and Outcome.

OBJECTIVE: To determine compliance and improvement in sustained viral response (SVR) by following response guided therapy (RGT) plan of interferon and ribavirin, for genotype 3 in chronic hepatitis C. METHODS: Patients with chronic hepatitis C genotype 3, who were eligible for interferon-ribavirin therapy and consented for RGT, were included. Those with no rapid viral response (RVR), having coarse echotexture of liver or undergoing re-treatment, were advised 48 week treatment whereas, rest had 24 week standard therapy. PCR for HCV RNA checked 6 months after discontinuing treatment, was the primary end point of study. RESULTS: Of 154 patients, included in the study with mean age of 39.9 (±10.84) and male to female ratio 1.4/1 (94/60), majority of patients, 136 (88.4%) were treatment naïve whereas, 18 (11.6%) were being retreated. On ultrasound, 63 (40.9%) patients had coarse liver and 33 (21.4%) had splenomegaly. RVR was achieved in 99 (64.3%) patients. Overall 66(42.8%) patients merited extended duration of therapy as per RGT plan but only 22 (33%) were compliant. Treatment related side effects were the dominant reason for declining RGT in 33 (75%) patients. SVR was noted in 111 (72.1%) patients. Those patients with extended therapy (RGT), had SVR 90.9% (20/22), although, better but statistically not significant than those who stopped therapy at 6 months 77.2% (34/44) (p value 0.11). CONCLUSION: Response guided therapy plan did not improve SVR to pegylatedinterferon and ribavirin therapy in patients with genotype 3 and it has low patient compliance due to treatment related side effects.

Predicting Prognosis in Hepatocellular Carcinoma: Comparison of Staging Systems in Pakistani Cohort.

OBJECTIVE: To determine the clinical, biochemical and radiological prognostic indicators and to compare the performance of six staging systems in patients of hepatocellular carcinoma (HCC). STUDY DESIGN: Descriptive study. PLACE AND DURATION OF STUDY: Department of Gastroenterology, Doctors Hospital, Lahore, from October 2007 to December 2013. METHODOLOGY: Patients with HCC were included. Baseline clinical, hematological and radiological variables were noted. Patients were followed for 5 years or till death. Survival predictors were identified using Cox proportional hazard analysis and 6 prognostic staging systems were evaluated by determining homogeneity, discriminatory ability and monotonicity. RESULTS: Of the 228 patients included, male to female ratio was 2.6/1 (165/63) and mean age was 56.5 ±10.4 years. Majority of patients 189 (82.9%) were anti-HCV positive. Solitary HCC lesion was seen in 121 (53.1%) patients, 16 (7%) had 2 lesions while 73 (32%) had 3 or more lesions. Only 36 (15.8%) patients had palliative therapy for HCC. Survival rate was 45.2%, 25%, 12.3%, 7%, 2.2% and 1% for 6 months, 1, 2, 3, 4 and 5 years respectively. Male gender, portal vein thrombosis, serum albumin < 3.5 g/dl, tumor size ≥6 cm and alpha fetoprotein (AFP) ≥147 U/ml were bad prognostic indicators. OKUDA, GRETCH and early stages of CLIP had better homogeneity while CLIP showed superior discriminatory ability and monotonicity for predicting survival. CONCLUSION: Male gender, presence of portal vein thrombosis, low serum albumin, large tumor size and high AFP level are poor prognostic indicators in patients of HCC. CLIP has better performance in predicting mortality.

COMPARISON OF SINGLE VERSES MULTIPLE SESSION BAND LIGATION FOR THE TREATMENT OF BLEEDING OESOPHAGEAL VARICES.

BACKGROUND: Cirrhosis of liver is the leading cause of portal hypertension in this part of the globe. Around thirty percent of the patient with portal hypertension develops complications. Oesophageal variceal bleeding is a serious complication of portal hypertension. Oesophageal variceal band ligation (EVBL) has become the standard of care for patients with bleeding oesophageal varices. Multiple sessions of band ligation are cumbersome and expensive. METHODS: Sixty patients with acute variceal bleed were enrolled in this randomized control trial. Patients were randomly assigned to multi-session (group A) or single session (group B) oesophageal variceal band ligation group. All. patients were followed for re-bleeding and mortality up to three months. RESULTS: Re-bleeding occurred (20%) in group A and (17%) in group B patients, respectively. Mortality was 10% in group A and 7% in group B patients. Variceal obliteration was better in group A 63% than group B 24% (p<0.05). CONCLUSION: Single session band ligation was comparable for rates of re-bleeding and mortality to multi-session band ligation.
