Vitamin D status among vegetarians and non-vegetarians.

Background: Vitamin D helps in maintaining bone and muscle health. Vitamin D deficiency is a global problem, with the prevalence of deficiency being widespread in Pakistan. The present study was planned to associate serum vitamin D, Parathyroid Hormone (PTH), calcium and phosphate concentrations with dietary habits of individuals living in urban/rural areas of Sindh, Pakistan.

Prevalence of microalbuminuria with relation to glycemic control in type-2 diabetic patients in Karachi.

Background: Diabetes is one of the most common endocrine disorders characterized by hyperglycaemia. Diabetic nephropathy is a consequence of long standing diabetes. The prevalence of microalbuminuria predicts progression to diabetic nephropathy.

Hepatocellular carcinoma (HCC) and diagnostic significance of A-fetoprotein (AFP).

Background: Alpha-fetoprotein (alpha-fetoprotein, AFP) is a Glycoprotein, belonging to the intriguing class of onco-development protein. Generally designated as tumour marker, AFP is recognized as an important blood component, having specific diagnostic utilities Elevation of its level up to pathological range in adults correlate with the appearance of several malignant and chronic conditions, such as hepatocellular carcinoma (HCC) and chronic liver disease, respectively.

Methods: To evaluate the diagnostic significance of AFP in HCC, a study was carried out for a period of two years (Jan 2004 to Dec 2005) A brief history of Patients was taken with clinical symptoms and signs and initial diagnosis.

Anti-inflammatory role of methotrexate in adjuvant arthritis: effect on substance p and calcitonin gene-related Peptide in thymus and spleen.

Objective: To investigate the anti-inflammatory effect of methotrexate (MTX) in rats with adjuvant arthritis through its influence on the expression of proinflammatory neuropeptides, substance P (SP) and calcitonin gene-related peptide (CGRP) in immune organs, thymus and spleen.

Design: Phase-I pre-clinical trial.

Place And Duration Of Study: The Aga Khan University, Karachi, from July to December 2003.

Polymorphism of HLA-DR and HLA-DQ in rheumatoid arthritis patients and clinical response to methotrexate--a hospital-based study.

Objective: To investigate the frequency and distribution of DRB1 and DQB1 alleles in Patients with rheumatoid arthritis (RA) and analyze the relationship between clinical response to methotrexate (MTX) and the HLA-DR and HLA-DQ genotypes in these patients.

Methods: In this case-control study, the HLA-DRB1 and HLA-DQB1 polymorphism in 91 RA patients and 91 healthy controls was done using polymerase chain reaction and sequence specific primers.

Results: There was no statistical difference in frequencies of HLA-DRB1*03, DRB1*04, DRB1*07, DRB1*10, DRB1*11, DRB1*12, DRB1*13, DRB1*14, DRB1*15 and DRB1*16 genotypes between patients and controls.
