Quantitative estimation and correlation of serum albumin levels in clinically healthy subjects and chronic periodontitis patients
ABSTRACT The aim of this study was to evaluate the relationship between periodontal disease and general health status in adults using the serum albumin concentration.
A total of 100 patients of both genders with age range of 40 to 70 years were included in the study. Patients were divided into the following two groups: clinically healthy subjects and patients with periodontitis, that is, loss of attachment ≥5 mm. Dental examinations were carried out at baseline and clinical attachment levels were measured at four sites. Serum albumin concentration was estimated by bromocresol green albumin method.
The mean serum albumin levels for Group I was 4.47 g/dl with standard deviation (SD) of 0.276 and for Group II, the mean value of serum albumin was 4.61 g/dl with SD of 0.273. Using Student's unpaired 't' test, the difference between the serum albumin levels in Group I and Group II were found to be statistically significant (P=0.020). The mean body mass index values for Group I was 22.63 with a SD of 3.85, whereas the same for Group II was 22.23 with a SD of 4.21, which were on comparison, found to be nonsignificant (P=0.462).
The findings of the clinical trial suggest an inverse relationship between the serum albumin concentration and chronic periodontal disease.

ABSTRACT: Fusarium is the major causative agent of fungal infections leading to corneal ulcer (keratitis) in Southern India and other tropical countries. Keratitis caused by Fusarium is a difficult disease to treat unless antifungal therapy is initiated during the early stages of infection. In this study tear proteins were prepared from keratitis patients classified based on the duration of infection. Among the patients recruited, early infection (n = 35), intermediate (n = 20), late (n = 11), samples from five patients in each group were pooled for analysis. Control samples were a pool of samples from 20 patients. Proteins were separated on difference gel electrophoresis (DIGE) and the differentially expressed proteins were quantified using DeCyder software analysis. The following differentially expressed proteins namely alpha-1-antitrypsin, haptoglobin α2 chain, zinc-alpha-2-glycoprotein, apolipoprotein, albumin, haptoglobin precursor - β chain, lactoferrin, lacrimal lipocalin precursor, cystatin SA III precursor, lacritin precursor were identified using mass spectrometry. Variation in the expression level of some of the proteins was confirmed using western blot analysis. This is the first report to show stage specific tear protein profile in fungal keratitis patients. Validation of this data using a much larger sample set could lead to clinical application of these findings.PLoS ONE 01/2013; 8(1):e53018. DOI:10.1371/journal.pone.0053018 · 3.53 Impact Factor
