Department of Pathology and Laboratory Medicine

Objectives:
In this study, we sought to establish a correlation between consumption of flouoroquinolones in our hospital and the emergence of ofloxacin resistant strains of E. coli in the urinary specimens. Data of all urinary samples, received at Aga Khan University Hospital between January 1995 and December 2002, was retrieved and analyzed. Specimens yielding E-coli as an isolate were included in this study.
Methods:
E. coli Isolates showing >103 colonies were identified using standard microbiological techniques. Antibiotic susceptibility of E. coli was tested using Kirby Bauer disc diffusion method. Antimicrobial usage data, obtained through hospital Pharmacy as unit utilized per …

Evaluation Of Frequency Of Isolation And Trends In Antibiotic Resistance Among Campylobacter Isolates Over 11 Year Period, N G. Ibrahim, Afia Zafar, Rumina Hasan

Department of Pathology and Laboratory Medicine

Objective:
To analyze frequency of isolation and trends in antibiotic resistance among Campylobacter isolates over 11 year period in Microbiology Laboratory, Aga Khan University from the year 1992-2002.
Methods:
Total 52,777 stool specimens were processed during the study period. Enteric pathogens isolated from 8,483 stool samples were further analyzed for frequency of isolation and antimicrobial resistance. Statistical Analysis was done by using descriptive statistics of SPSS version 10. Values were expressed as percentages, mean and rates.
Results:
Campylobacter species were third in frequency of isolation with an isolation rate of 24.8%. C. jejuni was the predominant pathogen followed by C.coli. …

Q-Probes Study Of Replicate Specimens At The Clinical Laboratory, The Aga Khan University Hospital, Karachi, L Ali, I Siddiqui

Department of Pathology and Laboratory Medicine

Objective: The aim of this Q-probes study was to evaluate the precision of replicate specimens.Methods: This Q-probes study done at the Clinical Laboratory, The Aga Khan University Hospital Karachi is about routine chemistry analytes because of their importance in critical care patients. The analytes data was collected for six months from April to September 2002. There were total 358 samples, which were given for reanalysis during this period under the constant working conditions. After analysis, results of both the runs on different days, were compared to determine the percent difference between the results. After calculating the percent difference, the results …

Increased Expression Of Hla Dr2 In Acquired Aplastic Anemia And Its Impact On Response To Immunosuppressive Therapy, M. Usman, Salman Adil, Tariq Moatter, F. Bilwani, S. Arian, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

Objective: To study the frequency of HLA DR2 status of patients with aplastic anemia and their response to immunosuppressive therapy at a tertiary care hospital.
Methods: Thirty eight consecutive patients of acquired aplastic anemia were evaluated with respect to demographic features, severity of HLA DR2 status and response outcome to immunosuppressive therapy.
Results: The mean age of the patients was 24.6 years + 16.4 with a male to female ratio of 2.8:1. Positivity of HLA DR2 was markedly high in acquired aplastic anemia patients. Twenty four (65%) out of 38 patients as compared to 45 (15%) of …

Polycythemia Vera And Idiopathic Erythrocytosis: Comparison Of Clinical And Laboratory Parameters, M. Usman, F. Bilwani, G. N. Kakepoto, Salman Adil, R. Sajid, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

Objective: To evaluate the various clinical and laboratory parameters of Polycythemia vera and idiopathic erythrocytosis in order to differentiate between two entities at the Aga Khan University Hospital.
Methods: Twenty six patients of polycythemia vera and 34 patients of idiopathic erythrocytosis were analyzed with respect to clinical features and laboratory findings.
Results: Patients with idiopathic erythrocytosis were males with a mean age of 41 years and no splenomegaly. Patients with polycythemia were older males and females with splenomegaly, red cell count of mor than 6.5 million/cmm, haematocrit 55%, leucocytosis, thrombocytosis and low erythropoietin level.
Conclusion: Based …

Prevalence Of Hepatitis C Virus In Lymphoproliferative Disorders, F. Bilwani, Y. Zaidi, G. N. Kakepoto, Salman Adil, Mohammad Khurshid

Department of Pathology and Laboratory Medicine

Objective: To study the prevalence of hepatitis C virus in lymphoproliferative disorders.
Methods: A case control prospective study was performed on 143 patients with lymphoproliferative disorders and 29 patients with non-hematological malignancies were taken as controls. All the patients in both groups were analyzed for various risk factors for infection with hepatitis C virus and were tested for the presence of hepatitis C virus antibody (anti HCV), cryoglobulins and rheumatoid factor antibody. Hepatitis C viremia was documented by detection of HCV RNA by polymerase chain reaction.
Results: There was no significant difference for risk factors for hepatitis …
