Beta2-glycoprotein I dependent anticardiolipin antibodies and lupus anticoagulant in patients with recurrent pregnancy loss.

AIM: The present study was aimed to define the incidence of antiphospholipid antibodies of different types lupus anticoagulant (LAC), venereal disease research laboratory test (VDRL) and Beta2-glycoprotein I dependent anticardiolipin antibodies Beta2 I aCL) in our cohort of population experiencing recurrent pregnancy loss (RPL) from Andhra Pradesh, South India. SETTING AND DESIGN: A referral case-control study at a tertiary centre over a period of 5 years. PARTICIPANTS: 150 couples experiencing 3 or more recurrent pregnancy losses with similar number of matched controls. MATERIAL AND METHODS: LAC activity was measured by the activated partial thromboplastin time (aPTT) according to the method of Proctor and Rapaport with relevant modifications. VDRL analysis was performed by the kit method supplied by Ranbaxy Diagnostics Limited and Beta2 Glycoprotein I dependent anticardiolipin antibodies were estimated by ELISA kit (ORGen Tech, GmbH, Germany) with human Beta2 Glycoprotein I as co-factor. STATISTICAL ANALYSIS: Statistical analysis was performed using Student's t test. RESULTS: LAC activity was found positive in 11 women (10.28%). The mean +/- SE Beta2 I aCL concentration in the study group was 14.53 (micro/ml) +/- 1.79 (range 0 to 90.4 micro/ml) which was higher than the control group with a mean +/- SE of 7.26 (micro/ml) +/- 0.40 (range 0 to 18 u/ml). The binding of the antibodies to the antigen was observed in 40.24% (n=33) of the cases compared to 6.09% (n=5) in controls. VDRL test was positive in 7(2.34%) individuals (3 couples and 1 male partner) and none among controls. CONCLUSIONS: The present study indicates the importance of antiphospholipid antibodies in women experiencing RPL and suggests the usefulness of screening for these antibodies as a mandatory routine for instituting efficient therapeutic regimens for a successful outcome of pregnancy.

Adenosine deaminase in cord blood as an immunoenzyme marker in low birth weight neonates.

Adenosine Deaminase (ADA) levels were estimated in cord blood of 30 neonates born with birth weight less than or equal to 2.5 kg and 30 neonates born with birth weight greater than 2.5 kg. The mean ADA levels in low birth weight (LBW) group was found to be 6.94 U/L and in normal birth weight group the mean ADA levels were 14.37 U/L which was statistically significant. Therefore ADA may be useful in assessing CMI status in low birth weight infants.

Effect of Lactobacillus supplementation on immune status of malnourished pre-school children.

The present study was undertaken to assess the effect of Lactobacillus supplementation on immune response of pre-school children. Thirty malnourished (grade I and grade II) pre-school (3-5 years old) children were selected for the study. These were further categorized into three groups 'A', 'B' and 'C', each group comprising of 10 individuals. Groups 'A' and 'B' were given lactobacillus supplementation 1.0 x 10(8) million viable spores/day/child and 2.0 x 10(8) million of viable spores/day/child for 90 days respectively. Group 'C' served as control. Serum adenosine deaminase (ADA) which is an important immuno enzyme marker for assessing lymphocyte function and proliferation was determined at different intervals. The results revealed that lactobacillus supplementation at level of 1.0 x 10(8) million viable spores/day/child for 15 days along with regular diet significantly improved the ADA levels of pre-school children indicating therapeutic value of lactobacillus as supplementation to malnourished pre-school children.

Effect of handwashing agents on bacterial contamination.

In order to assess the effect of handwashing agents like soap and ash on the control of bacterial contamination, the study was carried out in two villages of Rajendranagar mandal of Rangareddy district, Andhra Pradesh. Twenty households belonging to high income group and twenty households belonging to low income group having 1-2 years age children were randomly selected for the study handwash samples. Before feeding the child handwash samples after washing with different agents were collected and analysed for bacterial contamination. The study revealed that use of soap or ash for washing hands before feeding the child reduced hand contamination significantly.
