Introduction: Viral hepatitis and other liver-related diseases are mostly difficult to diagnose solely based on clinical regimes. Liver damage results in alterations in serum enzyme patterns which have been used to develop many enzyme-based assays. Aim and objectives: The major clinical consequences of chronic liver disease can be evaluated by liver function tests like bilirubin, gamma-glutamyl transferase (GGT), aspartate aminotransferase (AST), and alanine transaminase (ALT). Alanine transaminase and AST changes indicate leakage from damaged hepatocytes. The present study was conducted to compare the serum levels of GGT, AST, ALT, AST:ALT ratio, and bilirubin in patients with chronic hepatitis. Materials and methods: The study group comprised 100 clinically diagnosed patients with chronic hepatitis and 100 controls. Results: Case–control comparison showed statistically higher values of GGT (p < 0.01), AST (p < 0.05), ALT (p < 0.05), AST:ALT (p < 0.01), and bilirubin (p < 0.05) in cases and serum levels of GGT, AST:ALT, and bilirubin were sensitive and specific when various parameters were compared with each other in various hepatitis and controls. Conclusion: The present study indicates that the parameters GGT, AST, ALT, AST:ALT ratio, and bilirubin are associated with increased risk of hepatitis. Clinical significance: The serum levels of GGT, AST, ALT, AST:ALT ratio, and bilirubin can be used for the biochemical profiling of different types of patients with hepatitis.

Retrospective Assessment of Antinuclear Antibody by Indirect Immunofluorescence Microscopy and Immunoblot in Patients with Polyarthritis

[Year:2022] [Month:September-December] [Volume:26] [Number:3] [Pages:4] [Pages No:77 - 80]

Keywords: Antinuclear antibody, Immunoblot, Immunofluorescence microscopy, Polyarthritis

   DOI: 10.5005/jp-journals-10054-0209  |  Open Access |  How to cite  | 


Introduction: Detection of antinuclear antibody (ANA) by immunofluorescence assay (IFA) is the method of choice for screening autoimmune polyarthritis, where the different patterns are etched in the cellular components as per the group of antibodies present in the patient. Like all other screening tests, it has its sensitivity and specificity, and the final confirmation is done by doing a multispot immunoblot testing, where the specific antibodies against a specific antigen is detected. Aims and objectives: The study aimed at finding out the sensitivity and specificity of IFA with respect to immunoblot assay and to detect whether any pattern can be detected to attribute to false-positive and false-negative cases. Materials and methods: The conducted study is a retrospective analysis of 100 reports available from the Laboratory Information System. Patients referred by rheumatologists with clinical polyarthritis prescribed for both ANA by IFA and immunoblot are taken for the study. Sensitivity and specificity of ANA by IFA is calculated taking immunoblot as confirmatory gold standard. Results: The sensitivity and specificity were calculated as 80 and 84.3%, respectively, in polyarthritis cases and anticell (AC)-1 and AC-4 were implicated in most of the false-positive and false-negative cases. Conclusion: Antinuclear antibody by IFA needs confirmation by immunoblot for antibody profile characterization. AC-1 and AC-4 if detected on IFA mandates for immunoblot as most of the false positives and negatives are implicated with these patterns.

Assay of Serum Iron and TIBC: A Preliminary Study for Survey Shortlisting Suspected Tuberculosis Patients

[Year:2022] [Month:September-December] [Volume:26] [Number:3] [Pages:6] [Pages No:81 - 86]

Keywords: Carboxymycobactin, Mycobactin, Siderophores, Superoxide dismutase, Transferrin

   DOI: 10.5005/jp-journals-10054-0210  |  Open Access |  How to cite  | 


Aim: Mycobacterium tuberculosis (Mtb) growing within the phagosome of macrophases secretes siderophores, a small molecule having a high affinity for Fe+3 iron, to take up iron-loaded mycobactin (MBT) and carboxymycobactin (CMBT) from the environment to meet its iron (Fe) need. Mycobacterium tuberculosis is well capable to utilize Fe from heme and hemoglobin by the secretion of heme-binding protein, cell surface proteins, etc., by the mycobacteria. On the other hand, the measurement of serum total iron binding capacity (TIBC) denoting the maximum amount of Fe carried by transferrin (Tf) present in serum entails indirectly a measure of serum Tf level. The index author has interpreted the serum iron and serum TIBC level and the ratio of serum iron and serum TIBC as a preliminary survey to shortlist the suspected population deserving confirmatory test for tuberculosis (TB). This is to categorically declare that assay of these parameters is not to be used as TB diagnostic but only for shortlisting suspected TB patients from the general population. Materials and methods: The study was conducted on total of 180 participants divided into 3 groups: Group I - normal control (n = 45); Group II - lung disease control (n = 45); and Group III - patients suffering from TB (3A: Pulmonary TB (n = 45) and 3B: Extrapulmonary TB (n = 45)). Serum Fe and TIBC levels were measured for all participants and also for group III and group II subjects after one month with the usual treatment. The level of significance was assessed using Student's t-test. All the subjects in this study had normal liver function tests and they did not suffer from iron overload diseases or any malabsorption of iron syndrome. Result: At baseline, serum Fe was significantly high in TB patients whereas serum TIBC was significantly decreased. After one month's additional anti-TB (A-TB) drug treatment serum iron had increased but not significantly (p = 0.15) and serum TIBC had increased significantly (p = 0.04). Statistical computation of the ratio of serum Fe and serum TIBC in TB patients had shown to be as high as 0.63, and more than that. Conclusion: From statistical computation, it might be conferred that serum Fe more than 149 µg/dL and the ratio of serum Fe to serum TIBC more than 0.63 (which is more important) in preliminary survey detecting TB patients would shortlist the TB suspects deserving confirmatory test for TB diagnosis.

Serum Vitamin D and Uric Acid Levels in Glaucoma Patients: A Comprehensive Investigation

[Year:2022] [Month:September-December] [Volume:26] [Number:3] [Pages:3] [Pages No:87 - 89]

Keywords: Glaucoma, Optic nerve, Radioimmunoassay, Uric acid, Vitamin D

   DOI: 10.5005/jp-journals-10054-0211  |  Open Access |  How to cite  | 


Objective: Glaucoma is an eye condition characterized by optic nerve damage due to inflammation and oxidative stress, often associated with increased intraocular pressure (IOP). Vitamin D, a fat-soluble vitamin with anti-inflammatory properties, and uric acid (UA), an antioxidant molecule capable of scavenging nitrogen radicals and superoxide in plasma, were the specific biomarkers of interest in this research. Therefore, the aim of this study was to assess serum levels of vitamin D and UA in glaucoma patients within the North Indian population. Materials and methods: The study enrolled 45 age and sex-matched controls and 45 glaucoma patients. Serum levels of vitamin D and UA were measured using the radioimmunoassay (RIA) and enzymatic methods, respectively. Results: The analysis revealed that the mean of vitamin D in the test group was 23.42 ± 6.56 (ng/mL), while in the control group, it was 29.28 ± 2.58 (ng/mL). Similarly, the UA level was 4.57 ± 1.19 (mg/dL) in the test and 5.87 ± 1.74 in the control. Conclusion: The present research demonstrated that the level was significantly lowered in both vitamin D and UA in glaucoma patients compared to healthy individuals. These findings emphasize the importance of routinely estimating serum vitamin D and UA in individuals suspected of having glaucoma. Additionally, the results may prove valuable for ophthalmologists in managing and monitoring patients with glaucoma.
