OBJECTIVE: To assess the quality of gastrointestinal (GI) endoscopic procedures and patient satisfaction in endoscopy suite of South Asian country.

METHODS: Patients coming to the endoscopic suite of Aga Khan University Hospital (AKUH) were interviewed and assessed in this cross-sectional study. Quality of GI endoscopic procedures was evaluated using assessment tools as suggested by The American Society of Gastroenterology. Patient satisfaction after the procedure was assessed using a modified GHAA-9 questionnaire. The questionnaire was statistically evaluated using Pareto analysis and Spearman rank correlation.

RESULTS: In this study, 323 patients were evaluated with a mean age of 43 +/- 14.36 years. …

Frequency And Characteristic Features Of Portal Hypertensive Gastropathy In Patients With Viral Cirrhosis., Shahid Ahmed, Khalid Mumtaz, Umair Syed Ahmed, Hasnain Ali Shah, Shahab Abid, Saeed Hamid, Wasim Jafri

Section of Gastroenterology

To determine the frequency and specific characteristic features of portal hypertensive gastropathy (PHG) in cirrhosis due to viral etiology. Cross-sectional descriptive study. The Aga Khan University Hospital, Karachi, from June 2006 till June 2008. Patients with hepatitis B and C cirrhosis were included who underwent screening esophago-gastroduodenoscopy (EGD) for varices. Baveno III consensus statement was used for diagnosing PHG on endoscopy and divided them into two subgroups i.e. mild and severe. Data related to platelet/spleen ratio, MELD score and Child Turcotte Pugh (CTP) score indicating severity of cirrhosis were recorded in all patients. Findings were compared by using independent sample …

Prevalences Of Giardia Lamblia And Cryptosporidium Parvum Infection In Adults Presenting With Chronic Diarrhoea, Javed Yakoob, Zaigham Abbas, M. Asim Beg, Shagufta Naz, Rustam Khan, Muhammad Islam, Wasim Jafri

Section of Gastroenterology

iardia lamblia and Cryptosporidium parvum are both waterborne pathogens associated with diarrhoea in developing countries. In a recent study based at the Aga Khan University in Karachi, 334 adults aged 16–83 years (178 patients with chronic diarrhoea and 156 diarrhoea-free volunteers who acted as controls) were checked for infection with these parasites, using stool microscopy and/or PCR. Overall, 21 (6.3%) and 29 (8.7%) of the subjects were found positive for G. lamblia by microscopy and PCR, respectively, while the corresponding values for C. parvum were 13 (3.9%) and 14 (4.2%). Although, compared with the diarrhoea-free controls, the patients with diarrhoea …

Blastocystis Hominis And Dientamoeba Fragilis In Patients Fulfilling Irritable Bowel Syndrome Criteria., Javed Yakoob, Wasim Jafri, Mohammad Asim Beg,, Z Abbas, Shagufta Naz,, Muhammad Islam, Rustam Khan

Section of Gastroenterology

Studies have suggested a possible role for Blastocystis hominis and Dientamoeba fragilis in the etiology of irritable bowel syndrome (IBS). We studied the prevalence of B. hominis and D. fragilis in patients with IBS-diarrhea (IBS-D). Three hundred and thirty patients were enrolled, 171 (52%) with IBS-D and 159 (48%) were controls, respectively. Stool microscopy, culture, and polymerase chain reaction (PCR) for B. hominis and D. fragilis were done. B. hominis was positive by stool microscopy in 49% (83/171) of IBS compared to 24% (27/159) in control (p < 0.001). B. hominis culture was positive in 53% (90/171) in IBS compared to 16% (25/159) in control (p < 0.001). B. hominis PCR was positive in 44% (75/171) in IBS compared to 21% (33/159) in control (p < 0.001). D. fragilis microscopy was positive in 3.5% (6/171) in IBS-D compared to 0.6% (1/159) in control (p = 0.123). D. fragilis culture was positive in 4% (7/171) in IBS compared to 1.3% (2/159) in control (p = 0.176). D. fragilis PCR was positive in 4% (6/171) in IBS-D compared to 0% (0/159) in control (p = 0.030). B. hominis is common, while D. fragilis was less prevalent in our patients with IBS-D. B. hominis and D. fragilis culture had a better yield compared to stool microscopy and PCR.


Precipitating Factors And The Outcome Of Hepatic Encephalopathy In Liver Cirrhosis, Khalid Mumtaz, Umair Syed Ahmed, Shahab Abid, Noshaba Baig, Saeed Hamid, Wasim Jafri Aug 2010

Precipitating Factors And The Outcome Of Hepatic Encephalopathy In Liver Cirrhosis, Khalid Mumtaz, Umair Syed Ahmed, Shahab Abid, Noshaba Baig, Saeed Hamid, Wasim Jafri

Section of Gastroenterology

Objective: To determine precipitants of hepatic encephalopathy (HE) and their impact on hospital stay and mortality.

Study Design: Cross-sectional, analytical study. Place and Duration of Study: The Aga Khan University Hospital, from January 2005 to December 2007.

Methodology: Consecutive patients admitted with different grades of HE were evaluated between January 2005 and December 2007. The precipitants of HE were correlated with the different grades of HE, and length of hospital stay and mortality. Chi-square test was used to compare the proportion of precipitating factors versus hospital stay and grade with significance at p < 0.05.

Results: Of the 404 patients 252 (62%) …


Is There An Association Of Giardiasis With Beta-Thalassemia Minor?, Javed Yakoob, Wasim Jafri, Hizbullah Shaikh Jul 2010

Is There An Association Of Giardiasis With Beta-Thalassemia Minor?, Javed Yakoob, Wasim Jafri, Hizbullah Shaikh

Section of Gastroenterology

Beta–thalassemia minor is a symptomless carrier state of a hemoglobinopathy which predisposes to bacterial infections. We report three cases presenting with giardiasis, a parasitic infection of gastrointestinal tract caused by Giardia lamblia. Patients presented with recurrent diarrhea and abdominal pain for over a year. An esophagogastroduodenoscopy finding varied from normal to acute duodenitis. Duodenal biopsy demonstrated changes consistent with mild chronic non-specific inflammation with G. lamblia trophozoites. All three patients were diagnosed as β -thalassemia minor hemoglobin electrophoresis. They were treated with Diloxanide furoate 500 mg and Metronidazole 400mg three times daily for five days. Their symptoms resolved and a …

Irritable Bowel Syndrome: Is It Associated With Genotypes Of Blastocystis Hominis., Javed Yakoob, Wasim Jafri, Mohammad Asim Beg, Z Abbas, Shagufta Naz, Muhammad Islam, Rustam Khan

Section of Gastroenterology

Blastocystis hominis is the most common intestinal parasite in humans. An extensive genetic variability has been described recently in B. hominis isolates. The aim of this study was to analyze genotypes of B. hominis isolates obtained from the healthy individuals and patients with irritable bowel syndrome-diarrhea (IBS-D). The patients with IBS-D were enrolled from gastroenterology outpatient department at the Aga Khan University Hospital. History and physical examination was done. Stool microscopy, culture, and polymerase chain reaction for B. hominis genotyping were carried out. The study included 158 patients with IBS-D, mean age 41 +/- 15, age range 16-83 years, and …
