RESUMO

Objectives: To assess frailty in cirrhotic by calculating Liver Frailty Index (LFI) using bedside clinical tests and correlate it with Child-Turcotte-Pugh (CTP), MELD, MELD Na, Fib- 4 and Transient Elastography (TE) scores. Methods: This cross-sectional observational comparative study was carried out in Dr Ruth KM Pfau Civil Hospital, Karachi from August 2020 to September 2021. Patients were subjected to three performance-based testing including dominant hand grip strength (HGS), Chair to Stand (CTS) Time & Three Position Balance (TPB). LFI was calculated using the online LFI calculator, available at http://liverfrailtyindex.ucsf.edu and classified as 'Robust' if LFI <3.2, 'Prefrail' LFI between 3.2 and 4.4, and 'Frail' as LFI ≥4.5. Correlation of frailty with MELD, MELD-Na and CTP Scores was done. Means of MELD & MELD-Na Scores and CTP scores were calculated in all 3 classes of frailty using one way ANOVA. A p-value of ≤.05 was taken as significant. Results: Out of 118 patients, 62 (52.5%) were males. Mean MELD score was 11.4 ±3.3, MELD-Na was 15.97 ±8.54, CTP 8.25 ±2.21, Fib-4 was 2.79 ±1.034 and TE score was 18.20 ±9.17. Mean LFI was 3.87 ±1.07; mean HGS was 18.12 ±4.68; mean of CTS was 9.62 ±3.55. LFI Class distribution in our cohort showed Robust were 36 (30.5%), Prefrail 34 (28.8%) and Frail were 48 (40.8%). Correlation of all these variables with LFI showed significant correlation with LFI, but highest correlation coefficient was seen with MELD-Na. Conclusion: Significant correlation between frailty score in cirrhotic with cirrhosis severity scores highlights the need for frequently assessing LFI in all cirrhotic at regular follow up visits.

RESUMO

Objectives: To compare the efficacy of Vonoprazan based dual treatment versus PPI based treatment for the eradication of Helicobacter pylori infection. Methods: A randomized controlled trial was conducted in Department of Medicine/Gastroenterology Ruth KM Pfau Civil Hospital, DMC during the period of 22 June to 21 September 2021. Sample size was calculated as 96 in each Group. All patients of age 18-75 years with Helicobacter Pylori Infection were inducted and randomly allocated to two groups. Group-A: were given Capsule Amoxicillin 1 gm; Tablet Clarithromycin 500 mg; Capsule Omeprazole 20 mg all medications were given twice daily for two weeks. Group-B were given Capsule Amoxicillin 1 gm; Tablet Vonoprazan 20 mg (Vonozon©, m/s Getz Pharma, Pakistan) twice daily for two weeks. Confirmation of Hp eradication was done by stool Hp antigen test four weeks after completion of treatment. Nine and four patients were lost to follow-up in Group-A & B respectively. Analysis was conducted on 87 patients in Group-A and 92 patients in Group-B. Results: Out of eighty-seven patients in Group-A and ninety-two patients in Group-B, 73 (83.9%) patients in Group-A and 86 (93.5%) patients in Group-B had negative H pylori result respectively after treatment (p = .042). Significantly higher frequencies of adverse events were observed in Group-A as compared to Group-B in nausea/vomiting (p = .035) and bloating (p = .045). Conclusion: VA-dual provides an acceptable eradication rate with fewer adverse events.

RESUMO

INTRODUCTION: Gastro-esophageal reflux disease (GERD) is a common gastrointestinal disorder that occurs when backflow of the gastric contents into the esophagus results in troublesome symptoms. Though GERD has been extensively studied in Western populations, literature on the management of GERD in patients in Africa and Middle East (AME) is scarce. AREAS COVERED: In this review, we provide an overview of the management of mild-to-moderate GERD in AME. Here we focus on the efficacy and safety of currently available treatments for GERD to help physicians and community pharmacists appropriately manage patients with mild-to-moderate GERD in the primary healthcare setting, detailing specific situations and patient scenarios that are relevant to the region, including management of GERD during Ramadan and post-bariatric surgery. EXPERT OPINION: Under-appreciation of the burden of GERD in the region has resulted in a lack of consensus on management. Barriers that currently prevent the adoption of treatment guidelines in the primary healthcare setting may include lack of availability of local guidelines and referral systems, a paucity of region-specific research, and dogmatic adherence to traditional practice. By increasing awareness, strengthening knowledge, and by more effective utilization of resources, physicians and pharmacists could optimize GERD management strategies to better support patients.

RESUMO

OBJECTIVES: This study aimed to validate Baveno-VI recommendations for variceal screening in cACLD in our region and proposed our own cutoff values. METHODS: Prospective cross-sectional study was conducted on cACLD patients from August 2020 till April 2021. Patients segregated into Group-A, having Liver stiffness measurement (LSM) of ≥ 20 kPa and platelet of ≤ 150 × 109 cells/L; and Group-B having LSM of < 20 kPa and PLT of > 150 × 109 cells/L. Gastroscopic findings were segregated into three categories, VNT, Varices Not Needing Treatment (VNNT) and No Varix (NV). ROC plots were generated for LSM and Platelet for VNT for sensitivity, specificity, Negative and Positive Predictive Values were calculated. RESULTS: A total of 134 patients of cACLD were included. Group-A had 72 (53.7%) patients and Group-B had 62 (46.3%) patients. Group-A had 6 (8.3%) NV; 18 (25.0%) VNNT and 48 (66.7%) VNT. Group-B had 26 (41.9%) NV, 24 (38.7%) VNNT and 12 (19.4%) VNT. The sensitivity of 66.7%, specificity of 80.6% and NPV of 67.56% was obtained. Thus 19.4% VNT were missed on following Baveno VI recommendations. ROC in our study suggested cutoff value of 11.5 kPa with sensitivity of 100% and 1-sepcifity pf 78% (AUROC = 0.865; p < .001) of LSM below which screening gastroscopy could be avoided. The positive and negative predicted values for 84.85% and 100% respectively. Cut off value of platelet count for VNNT came out to be ≥ 97.5 × 109 cells/L with AUROC 0.891 (p < .001), having sensitivity of 100 % and 1-specificity of 83.3%. CONCLUSIONS: Substantial number of VNT in cACLD patients are missed by following Baveno-VI recommendations and these needs to be revised on regional basis.

RESUMO

OBJECTIVE: To compare 7-Day All-Cause Mortality among HDU Patients with Modified Early Warning Score of ≥5 with Those with Score of <5. METHODS: All patients of age more than 18 years, of either gender admitted in HDU of Medical Unit-II, CHK between September 2019 to February 2020 were included. MEWS was calculated for each patient at time of admission. Patients with MEWS score of ≥5 were allocated to Group-A and those with score of <5 were allocated to Group-B. Patients were followed for seven days and outcome status of alive, expired or discharged was noted. RESULTS: Total of 336 patients were selected out of which 168 patients was inducted in Group-A and 168 patients in Group-B. MEWS Score in patients who expired was significantly higher (Mdn=11) than in those who survived (Mdn=4), p <.001. 7-day mortality in Group-A was 62 (39.9%) while in Group-B was 40 (23.8%). ROC was plotted of MEWS Score for mortality, it showed significant area under curve of 68.4% (p <.001, 95% CI = .62 to .75). MEWS Score of 3.5 showed sensitivity of 89.2% and specificity of 65%. CONCLUSION: Our results show that MEWS has a positive trend to predict mortality. MEWS score of 3.5 is suggested cut off based on ROC in our study.

RESUMO

OBJECTIVE: To determine frequency of Muscle Weakness in Non-Hypoxemic COPD out-patients and Comparison with age matched non-COPD Controls. METHODS: This cross-sectional study was conducted at OPD of Ojha Institute of Chest Diseases and Medicine, Dow University of Health Sciences, Karachi, Pakistan, during the period 8th September 2019 till 30th May 2020. Patients of both genders aged 25-70 years who were satisfying GOLD criteria for COPD and having SpO2 ≥ 94% were included. An age matched control group was added as control. Hand Grip Strength (HGS) and Chair to Stand time (CST) were recorded. RESULTS: Two hundred fifty-six patients were inducted with aged and BMI matched group of non-COPD Control patients in ratio of 1:2 (n = 128). Comparison of HGS between Control and COPD Groups showed significant weakness in COPD group. Significant weakness in lower limbs in COPD Group with longer timings to complete the task. Mean FEV1 had significant low values in COPD Group. Age correlated negatively with HGS & positively with CST. BMI correlated positively with FEV1 and CST but negatively with HGS. HGS correlated positively with FEV1 and no correlation was found with CST. No correlation was found of CST with FEV1. CONCLUSION: Muscle weakness in COPD patients was shown by simple validated bedside tools. The older COPD patients had less HGS and were slower in doing CST whereas those COPD ones who had higher FEV1 had more HGS.

RESUMO

OBJECTIVES: This study was conducted to determine the impact of insulin resistance using Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) score and BMI in non-hypoxemic out-patients with COPD on FEV1 using linear and polynomial regressions and to determine their correlation. METHODS: COPD patients of both genders were included after informed consent. Fasting blood sugar and serum insulin were done to calculate HOMA-IR, which were segregated into two groups of ≥ 3 and < 3 labeled insulin resistance present and absent, these were compared with BMI. Patients were segregated into GOLD Grade 1-4 per GOLD Guidelines and compared with HOMA-IR and BMI. Curve and linear regressions, multivariate and univariate analysis of HOMA-IR with BMI, FVC, and FEV1 were done. RESULTS: A total of 273 subjects were inducted after informed consent. There was a linear correlation between HOMA-IR and BMI (r2 0.498, P < 0.001) and nonlinear correlation between HOMA-IR and FEV1 (r2 0. 617, P < 0.001) which showed little evidence of association above FEV1 > 60 predicted, but a clear negative association below that. Significant increase in HOMA-IR was seen from GOLD-2 to 3 and from GOLD-3 to 4 classes. The impact of HOMA-IR on FEV1 was 49.9% (P < 0.001) on FVC was 43.7%. CONCLUSIONS: The results indicate that there is a high prevalence of IR in non-hypoxemic COPD. A nonlinear association is present between FEV1 and HOMA-IR which is most evident with FEV1 <60% predicted.

RESUMO

OBJECTIVE: To determine the frequency of hyponatremia in patients taking Sodium Picosulfate Solution (SPS) solution for bowel preparation prior to colonoscopy and to compare serum sodium levels before and after SPS. METHODS: This interventional study was conducted at Dr. Ruth K. M. Pfau, Civil Hospital Karachi between June 2019 to November 2019. Patients undergoing colonoscopy were included in the study. All patients were given SPS. Two samples of blood for electrolytes were taken, one 30 minutes before taking SPS solution and another 30 minutes before colonoscopy. Paired sample t-test was used to determine the difference between serum sodium level before taking the colonoscopy solution and serum sodium level before colonoscopy. RESULTS: Fifty- four patients fulfilling inclusion criteria were included. Out of the 54 patients 28 (51.9%) were males and 26 (48.1%) were females. Mean sodium levels before taking colonoscopy solution was 139.7 ±3.5 mEq/L and mean sodium level before colonoscopy was 138.9 ±3.8 mEq/L. The difference between serum sodium level before taking SPS colonoscopy solution and before colonoscopy was found to be statistically insignificant (t (53) = 1.308; p = 0.196). CONCLUSION: No serious adverse effects were reported in any of our patients. There was no significant difference in the serum sodium level of patients undergoing colonoscopy before taking SPS bowel preparation solution and serum sodium level before colonoscopy.

RESUMO

Approximately one half of patients develop ascites within 10 years of diagnosis of compensated cirrhosis. It is a poor prognostic indicator, with only 50% surviving beyond two years. Mortality worsens significantly to 20% to 50% at one year if the ascites becomes refractory to medical therapy. Pakistan has one of the highest prevalence of viral hepatitis in the world and patients with ascites secondary to liver cirrhosis make a major percentage of both inpatient and outpatient burden. Studies indicate that over 80% of patients admitted with ascites have liver cirrhosis as the cause. This expert opinion suggests proper assessment of patients with ascites in the presence of underlying cirrhosis. This expert opinion includes appropriate diagnosis and management of uncomplicated ascites, refractory ascites and complicated ascites (including spontaneous bacterial peritonitis (SBP) ascites, hepatorenal syndrome (HRS) and hyponatremia. The purpose behind this expert opinion is to help consultants, postgraduate trainees, medical officers and primary care physicians optimally manage their patients with cirrhosis and ascites in a resource constrained setting as is often encountered in a developing country like Pakistan.

RESUMO

OBJECTIVE: To determine correlation between transient elastography values with serum ferritin and duration of infection in patients of hepatitis C. METHODS: A cross-sectional study was conducted at medical units of Civil Hospital, Karachi. The study protocol was approved by the Research Evaluation Unit of College of Physician and Surgeon Pakistan (CPSP). Patients fulfilling inclusion criteria were included after taking informed consent. Serum ferritin levels were tested by standard laboratory procedures and transient elastography by fibroscan. Regression analysis was done to see correlation of ferritin with transient elastography and duration of HCV. RESULTS: Over all 120 patients fulfilling the selection criteria were selected after informed consent. These included 68 (56.7%) male & 52 (43.3%) female. Significant differences in ferritin levels by Fibrosis stages were observed by ANOVA (df = 3; F =12.768; p = <0.001). Serum ferritin showed linear pattern across Fibrosis stages (F = 33.948; p = <0.001). Regression analysis of ferritin and duration of HCV showed significant impact on TE scores (r2 = 0.317). CONCLUSIONS: There is significant correlation between serum ferritin and duration of HCV with TE scores.

RESUMO

OBJECTIVE: To determine number of sessions of Endoscopic variceal band ligation required to obliterate the esophageal varices. METHODS: This study was conducted at Civil Hospital Karachi between June 2018 to April 2019. All patients undergoing endoscopic Variceal Band Ligation (EVBL) were inducted. Number of sessions of band ligation required to obliterate the varices were recorded. Number of EVBL sessions were correlated with Child-Pugh's Score and etiology of CLD by χ2 test, while it was compared with duration of Chronic Liver Disease (CLD) by One-way ANOVA test. RESULTS: One hundred ninety-two patients fulfilling selection criteria were admitted after informed consent. These included 101 (52.6%) males and 91 (47.4%) females. Most common cause of cirrhosis was HCV (66.7%) in our patients. Most of the patients were in Child Class-B (71.9%). Majority of patients (52.6%) underwent 3 sessions of EVBL while 68 (35.4%) underwent 4 sessions of EVBL. Duration of CLD was analyzed with number of sessions of EVBL by One-Way ANOVA test and it showed significant more sessions of EVBL were done with longer duration of CLD (p <0.001). CONCLUSION: Most patients underwent 3-4 sessions of EVBL for obliteration of varices. Number of EVBL sessions increased significantly with duration of disease.

RESUMO

OBJECTIVE: To determine effect of pre-endoscopy intake of simethicone solution on endoscopic mucosal visibility. METHODOLOGY: A randomized, single blinded placebo control trial was done in patients undergoing oesophago-gastro-duodenoscopy for any indication at DOTs Endoscopy Suite, CHK during the period of April to June 2019. Informed consent was taken. Patients were randomly allocated in two groups. Group-A received placebo while Group-B received Simethicone. Evaluation of mucosal visibility was assessed at 4 sites (oesophagus, fundus, antrum & duodenum) by previously validated scoring. Mean of visibility scores were compared in two groups. RESULTS: Two hundred and forty-eight patients were inducted and randomly allocate to two groups of 124 each. Mean of total sum of scores in Group-A was 8.14 ±2.44 and that of Group-B was 5.80 ±1.75 (p<0.001). Adequate visibility in Group-A was seen in 41.1% and that in Group-B was 78.2% (p<0.001). CONCLUSION: Use of Simethicone significantly improves mucosal visibility during OGD.

RESUMO

Objectives: To document frequency of non-specific impairment of lung functions (NILF) in patients of HCV and to compare according to gender, genotype, liver fibrosis score and smoking status. Methods: Patients of chronic hepatitis C were included after informed consent. Demographic data was recorded, and they underwent baseline investigations, fibroscan, abdominal ultrasound and PFT. Patients were segregated on basis of gender, fibroscan stages and smoking status. NILF was labelled if any two of three criteria are fulfilled (a) FVC < 80% of Predicted, (b) FEV1 < 80% Predicted, (c) FEV1/FVC ≥ 70. Results: Two hundred thirty four patients were of chronic HCV who fulfilled the selection criteria were inducted in study. These included 49.6% males and 50.4% females. There were 15.0% smokers, 16.2% were ex-smokers while 68.8% were never smokers. NILF was present in 130 (55.6%) out of which 61.5% were female and 38.5% were male (p <0.001), its presence in smokers was 56.2% and in never smokers was 55.3% (p=0.507). Presence of NILF increased with Fibroscan stages from F1 to F4 (p <0.001). Conclusions: NILF pattern on spirometry with normal chest radiograph is common among HCV patients. It was found more common in females and frequency increased progressively with fibro scan stages.

RESUMO

Objective: To determine level and factors of job satisfaction among doctors working in tertiary care hospitals in Pakistan. Methods: This is a multi-center cross-sectional survey conducted among Post graduate trainees, medical officers, consultants and faculty doctors. Job satisfaction was measured using 35 specific questions about sources of work-related stress and sources of work-related satisfaction. Satisfaction was defined if mean score of a factor was≥3.0, where factors were rated using a 5-point Linkert scale ranging from 1 (completely dissatisfied) to 5 (completely satisfied). Results: In this study 373 doctors participated, out of which 215(57.6%) were males. Over all mean satisfaction score was of 2.69 ±0.37. Departmental mean satisfaction scores were Internal medicine 2.71 ±0.35, Medical subspecialties 2.63 ±0.38, Surgical and allied 2.73 ±0.45. Designation means were Consultant 2.87 ±0.38, Faculty 2.78 ±0.44, Medical officer/ Registrar 2.50 ±0.32, Post graduate trainee 2.71 ±0.45. Public and private sector means satisfaction scores were 2.53 ±0.80 and 2.92 ±0.84 respectively. Conclusion: Job dissatisfaction was seen among doctors from all the tiers and departments. Public sector doctors were more dissatisfied than private sector doctors. Increasing age, duration of current posting and working experience, positively correlated with satisfaction level.

RESUMO

OBJECTIVE: To determine diagnostic yield of Closed Pleural Biopsy (CPB) and Cytology in Exudative Pleural Effusion (PE). METHODS: This prospective comparative study was conducted at Chest Unit-II & Medical Unit-IV of Dow University of Health Sciences, Karachi Pakistan from January 2011 till December 2014. RESULTS: Ninety-four patients with exudative PE were finally included. The mean age (SD) was 44.0 (13.8) years. Overall Specific Diagnosis was reached in 76/94 patients; 46 Tuberculosis PE (TPE) & 30 Malignant PE (MPE). CPB diagnosed all TPE patients alone and 28/30 of MPE. Cytology diagnosed only 10/30 patients of MPE with 8 patients having both CPB & Cytology positive for malignancy whereas in the remaining two cases only Cytology positive. The sensitivity of CPB in detecting TPE and MPE was 93.9% and 82.4% respectively whereas specificity for both was 100%. The diagnostic yield of cytology in detecting MPE is only (33.3%). The diagnostic yield of CPB for TPE and MPE is 100% and 93.3% respectively. The overall specific diagnostic yield of CPB is 78.7%. CONCLUSION: CPB is better than pleural fluid cytology alone with the later adding little to diagnostic yield when both combined in distinguishing TPE from MPE, the two main differential of exudative PE in a TB-Endemic country.

RESUMO

OBJECTIVE: To compare mean homeostatic model assessment of insulin resistance (HOMA-IR) in patients with and without chronic obstructive pulmonary disease (COPD). METHODS: A Case control analytic study was conducted in medical outpatient department of Medial Unit-II of Dow University of Health Sciences from April 2013 to September 2013. All patients with the diagnosis of COPD were included as cases. Controls were age match healthy individuals with minor illnesses. Age, weight, height and forced expiratory volume in one second to forced vital capacity (FEV1/FVC) ratio were documented. Fasting blood glucose and fasting insulin levels were done. Body mass index (BMI) and IR was calculated using the formulas. HOMA-IR was compared between cases and controls. RESULTS: Forty COPD patients were compared with thirty five age match controls. HOMA-IR was found to be higher in cases as compared to controls (2.85 v/s 2.00) with a p value <0.000. CONCLUSION: COPD is one of the chronic debilitating diseases in our region with various extra-pulmonary complications. We found IR to be present higher in COPD patients compared with healthy controls. Evaluating the pulmonary function as well as systemic metabolic parameters, may contribute to minimizing mortality and morbidity.

RESUMO

OBJECTIVE: To compare the efficacy of British Thoracic Society and American Thoracic Society guidelines for reintroduction of anti-tuberculous therapy after drug-induced liver injury, and to assess the ease of administration of each guideline on a scale of 1-10. METHODS: The randomised prospective interventional study was conducted at the Department of Medicine and Pulmonology, Dow University of Health Sciences, Karachi, from December 2011 to November 2013. Patients with anti-tuberculous therapy drug-induced liver injury were selected. Hepatotoxic anti-tuberculous therapy was stopped and modified anti-tuberculous therapy was started. Patients were followed weekly till clinical and biochemical parameters got stabilised. After stabilisation, the patients were randomised to one of the two groups to receive re-introduction of anti-tuberculous therapy under the guidelines of British Thoracic Society (Group I) or those of American Thoracic Society (Group II). Means of the groups were analysed by Student's t test and proportions were compared by chi-square test. Multivariate analysis was done for age, body mass index and serum albumin for recurrence of drug-induced liver injury after the re-introduction. P value < 0.05 was taken as significant. RESULTS: Of the total 325 patients, 163 (50.15%) were in Group I, while 162 (49.84%) were in Group II. The frequency of recurrence of drug-induced liver injury in Group I was 16 (9.8%) and in Group II it was 18 (11.1%).There was no statistically significant difference between the two groups (p < 0.7). Age was positively related with drug-induced liver injury, while body mass index and serum albumin were negatively associated. CONCLUSION: There was no significant difference between the two major guidelines though the American Thoracic Society guideline was easier to follow.
