Pill in the blister pack: a rare cause of dysphagia in an elderly adult

Foreign body impaction in the esophagus amongst adults is not a common cause of dysphagia. Fish bone, food bolus, dentures may cause symptoms of dysphagia, odynophagia, chest pain or respiratory distress. It needs prompt evaluation along with removal of the substance either surgically or endoscopically to avoid the development of life threatening complications. Here we are reporting a case of an elderly male, who presented to us with a history of absolute dysphagia for one week, as a consequence of ingestion of a pill in blister pack.

Factors predicting non-alcoholic steatohepatitis (NASH) and advanced fibrosis in patients with non-alcoholic fatty liver disease (NAFLD)

Introduction To determine the factors predicting non-alcoholic steatohepatitis (NASH) and advanced fibrosis in patients with non-alcoholic fatty liver disease (NAFLD). Methodology All patients aged >18 years and having a fatty liver on abdominal ultrasound (US), presenting from January 2011 to January 2017, were included. A liver biopsy was performed on all the patients. Results Of 96 patients undergoing liver biopsy for non-alcoholic fatty liver disease (NAFLD), 76 (79.2%) were men. On liver US, diffuse fatty liver (DFL) was noted in 68 (70.8%) patients. Liver biopsy showed non-alcoholic steatohepatitis (NASH) in 78 (81.3%) patients. Factors associated with NASH were male gender, body mass index (BMI) > 27 kg/m2, DFL and raised alanine aminotransferase (ALT). A GULAB score (based on gender, US liver findings, lipid (fasting) levels, ALT level and BMI) of ≥5 predicted NASH with 82.05% sensitivity. Factors associated with advanced fibrosis in NAFLD were age >40 years, diabetes mellitus, AST/ALT ratio > 1 and raised GGT. Conclusion NASH is common in patients with male gender, high BMI, DFL on liver US, raised ALT and GULAB score ≥5.

Upper Gastrointestinal Bleeding in Patients with End Stage Renal Disease: Causes, Characteristics and Factors Associated with Need for Endoscopic Therapeutic Intervention.

Abstract Background and Objectives The risk of upper gastrointestinal bleeding (UGIB) is increased among the end-stage renal disease (ESRD) patients. The aim of the current study was to describe the causes and characteristics of UGIB in ESRD patients at our center and to assess the need for endoscopic therapeutic intervention (ETI) using Rockall (RS) and Glasgow Blatchford scores (GBS). Material and Methods All patients with ESRD and UGIB with age ≥14 years were included. Frequencies and percentages were computed for categorical variables. Chi square test or Fischer’s exact test was used for statistical analysis. Results A total of 59 subjects had a mean age of 47.25 ± 15 years.The most common endoscopic findings seen were erosions in 33 (55.9%) patients, followed by ulcers in 18 (30.3%) patients. ETI was required in 33 (55.9%) patients, which included adrenaline injection in 19 (32.3%), hemoclip in 9 (15.2%) and argon plasma coagulation in 5 (8.4%) patients. Factors associated with the need of ETI were identified as: a combined presentation of hematemesis and melena (P=0.033), ulcer (P=0.002) and associated chronic liver disease (P=0.015). Six (10.1%) patients died. Death was more common if ETI was not performed (P=0.018). Conclusion ETI was more commonly required in patients on maintenance hemodialysis with UGIB, who had presence of combined hematemesis and melena, ulcers and associated chronic liver disease. A Glasgow Blatchford score of >14 was helpful in assessing the need for ETI in these patients.

The usage of complementary and alternative medicine in gastrointestinal patients visiting the outpatients’ department of a large tertiary care centre-views from Pakistan

Introduction The use of complementary and alternative medicine (CAM) has increased over the last few years, and an emergent data suggests that some CAM modalities may be helpful in addressing gastrointestinal (GI) conditions. Our aim was to find out the prevalence of such practices for GI condition amongst patients visiting an OPD of a large tertiary care centre of Karachi, Pakistan. Methods Patients visiting outpatient department of Hepatogastroenterology department at SIUT, Pakistan from March 2014 to March 2015, were included in this cross sectional study. A pre designed questionnaire was used that included the demographic data, primary disease of the patient, CAM modality used, reason for the use of CAM therapy and reasons for stopping it. Frequencies of different variables were computed using SPSS version 18. Results 906 patients were interviewed, out of which 52% (471) were males. The mean age at presentation was 39.81±12.4 years. 234 (25.8%) of the participants used one of the CAM modalities; Herbal medicine being most common one, seen in 122 (52.13%) followed by spiritual 61 (26%), and homeopathy 33 (14%). The duration of therapy was limited to six months in 161(68%), whereas 7 patients (2.9%) had prolonged duration of use of more than five years. Reasons for using CAM therapy included advice by family and friends in 66 patients (28%), personal will in 42 (17.94%), no benefit from allopathic treatment in 34 (14.5%), while high cost was the reason of use in 3(5%) of the patients. The most common reason for discontinuation of CAM was no benefit, seen in 113 patients (48.30%), followed by physicians advice in 32 (17%) patients, and side effects in 19 (8%). On the other hand 44 patients (18.80%) reported benefit from the therapy while 14 (5.9%) were still continuing with CAM modality. Among the CAM users 140 (60.09%) were un-educated or had primary education while CAM nonusers had 328 (47%) were either uneducated or had primary education only correlation reveals P value 0.004. Conclusion Significant numbers of patients used CAM therapy. A lower level of education was associated with increased usage of CAM while cost had no major impact on its usage.

Diagnostic accuracy of aspartate aminotransferase to platelet ratio index and fibrosis 4 scores in predicting advanced liver fibrosis in patients with end-stage renal disease and chronic viral hepatitis: Experience from Pakistan

Abstract Objectives The aim was to assess the diagnostic accuracy of APRI and FIB-4 in assessing the stage of liver fibrosis in end stage renal disease (ESRD) patients with chronic viral hepatitis and to compare the two tests with standard tru-cut liver biopsy. Material and Methods The study was conducted at Sindh Institute of Urology and Transplantation Karachi (SIUT) from May 2010 to May 2014. All ESRD patients, being considered as candidates for renal transplantation and in whom liver biopsy was performed were included. Fibrosis stage was assessed on liver biopsy using Ishak scoring system. The serum transaminases and platelet counts were used to calculate APRI and FIB-4 scores. Results Out of 109 patients, hepatitis C and B virus infections were present in 104 (95.4%) and 3(2.8%), respectively, while 2 (1.8%) patients had both infections. The mean Ishak fibrosis score was 1.95 ± 2. Advanced fibrosis was noted in 37 (34%) patients. Univariate analysis showed that advanced liver fibrosis was associated with lower platelets counts (P=0.001) and higher aspartate aminotransferase (AST) (P=0.001), alanine aminotransferase (ALT) (P=0.022), APRI score (P=0.001) and FIB-4 score (P=0.001). On logistic regression analysis, only APRI score (P < 0.001) was found to be the independent variable associated with advanced liver fibrosis. APRI score cutoff ≥1 indicating advanced fibrosis showed sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of 91.9%, 90.3%, 82.9%, 95.6%, respectively with area under the curve (AUC) of 0.97. Similarly, a FIB-4 score cutoff ≥1.1 had sensitivity, specificity, PPV and NPV of 70.27%, 66.67%, 52% and 81.36%, respectively with AUC of 0.74. Conclusion APRI is more accurate noninvasive test for assessing advanced liver fibrosis in ESRD patients as compared to FIB-4. It can be used to obviate the need for liver biopsy in this high risk population.

Clinicopathological Study of Seronegative Celiac Disease in Adults in Pakistan: A Pilot Study

BACKGROUND Celiac disease (CD) is usually missed, if the serology is negative. We aimed to evaluate the clinicopathological characteristics of seronegative CD (SNCD) and its response to gluten-free diet (GFD) in adult patients. METHODS This observational study was carried out at the Department of Hepatogastroenterology, Sindh Institute of Urology and Transplantation, Karachi, Pakistan from 2009 to 2015. All consecutive adult patients (≥17 years) with features of marked villous atrophy (Marsh class≥III) on duodenal biopsy, negative tissue transglutaminase IgA and IgG antibodies (anti-tTg IgA and IgG) and human leukocyte antigen (HLA) DQ2 or DQ8 serotypes were studied. Clinical characteristics, laboratory parameters, and response to GFD were analyzed by SPSS software version 20. Median and interquartile range (IQR) were used for summarizing quantitative data. Frequency (percentages) was used for qualitative data. RESULTS A total of 12 patients with median age of 31.5 years (IQR: 19.75-46.75 years), of whom five (41.6%) were men were studied. The presenting complaints were: weight loss in 11 (91.6%) and abdominal pain in 9 (75%) patients. Anemia was observed in 10 (83.3%) patients with median hemoglobin of 9.5 g/dL (IQR: 6.3-13.25 g/dL). Median alanine transaminase (ALT) was 21 U/L (IQR: 13–27 U/L) and median albumin was 3 g/dL (IQR: 2.4-3.6 g/dL). Anti-tTg IgA and IgG were negative in all patients. HLA DQ serotyping showed homozygous DQ2 and DQ8 in four and one patients, respectively; while heterozygous DQ2 and DQ8 in five and two patients, respectively. All patients were advised to receive GFD. Nine (75%) patients showed complete clinical response. Two patients were non-compliant and one with non-alcoholic fatty liver disease (NAFLD)-related cirrhosis had partial clinical response. Out of the nine responders, two patients showed response within 6 months while the remaining showed improvement over a year period. CONCLUSION The diagnosis of SNCD is rewarding as it responds favorably to GFD in most patients. HLA serology provides an important tool for diagnosis of this entity.

Celiac Crisis in Refractory Celiac Disease Type I with Neurological Manifestations: A Diagnostic Dilemma

Celiac crisis is a life-threatening condition in which patients have profuse diarrhea and severe metabolic disturbances. Refractory Celiac Disease (RCD) is a rare condition defined as persistence of symptoms despite being on Gluten Free Diet (GFD) for 6 months. Neurological involvement in Celiac Disease (CD) is seen in around 8 - 10% of adult patients; however, it is rare in children. Herein we present a case of an adolescent presenting with neurological symptoms and celiac crisis and diagnosed as RCD, type 1. He was treated with high dose steroids. This case underscores the need to consider RCD in patients presenting in celiac crisis and showing no improvement on GFD.
