Item Immunogenicity of low dose hepatitis B vaccine by the intradermal route & persistence of anti-HBs after three years.(1995-09-01) Jaiswal, S P; Asolkar, M V; Vijayvargiya, R; Chitnis, D SPlasma derived hepatitis B vaccine given intradermally (0.2 ml; 4 micrograms HBsAg) at 0, 1, 6 months to 200 health care workers, produced seroconversion in 97.5 per cent. Antibody levels to hepatitis B surface antigen (anti-HBs) crossed 1000 mIU/ml in 62 per cent while 26.5 per cent had levels of 100 to 1000 mIU/ml. Anti-HBs levels persisted in the same range in 41.7 per cent but dropped by a log in 58.3 per cent subjects at the end of 3 yr. Protective antibodies above 10 mIU/ml were documented in 93.3 per cent vaccinees after 3 yr. The 0.2 ml vaccine by intradermal (id) route was also found to give a good booster effect in another group of 27 persons who had received full dose vaccine 5 yr earlier. Thus, 0.2 ml vaccine by id route was safe, gave high seroconversion and persistent antibody levels over 3 yr and could offer effective protection at an economic cost.Item Prevalence of anti-delta antibodies in central India.(1999-01-28) Jaiswal, S P; Chitnis, D S; Artwani, K K; Naik, G; Jain, A KA total of 238 sera samples from cases of hepatitis, renal failure, thalassaemia, healthy health care workers (HCWs) & asymptomatic HBsAG carriers coming from central India from July 1992 to June 1998, were screened for anti-delta antibodies. Among 238 subjects, 206 were reactive for hepatitis B surface antigen (HBsAg) while 32 were HBsAg non-reactive. The prevalence of anti-delta antibodies was low (1.9%) among 54 patients of acute viral hepatitis (AVH) while it was higher (5.7%) among 52 patients of chronic liver disease (CLD). The anti-delta antibodies positivity among 34 patients with hepatic failure was around 15% and all of them were FHF patients. Among multitransfused subjects such as chronic renal failure (CRF) the prevalence of anti-delta antibodies was low (2.3%). None of the apparently healthy HBsAg reactive HCWs and asymptomatic HBV carriers were reactive for anti-delta antibodies. Similarly anti-delta antibodies could not be detected in HBsAg negative viral hepatitis patients. There is a wide variation in the prevalence of anti-delta antibodies in different parts of India. However, overall prevalence of anti-delta antibodies appears to be lower in the Indian population in comparision to western countries.Item Prevalence of anti-HCV antibodies in central India.(1996-08-01) Jaiswal, S P; Chitnis, D S; Naik, G; Artwani, K K; Pandit, C S; Salgia, P; Sepaha, AThe study group screened for anti-HCV comprised 789 subjects of hepatitis, renal failure, thalassaemia and healthy voluntary blood donors coming from Central India during July 1992 to November 1995. The prevalence of HCV was low (4.85%) among 103 patients of acute viral hepatitis (AVH) while it was higher (25.64%) among 117 patients of chronic liver disease (CLD) with the highest rate of 31.57 percent in 57 patients of cirrhosis. The anti-HCV positivity among 101 patients with hepatic failure was around 10 percent. High risk groups such as chronic renal failure (CRF) patients mainly on haemodialysis and thalassaemics receiving multiple blood transfusions showed the prevalence of anti-HCV in 41.9 and 25.45 percent respectively. Only 1.78 percent of the 280 voluntary blood donors showed positivity for anti-HCV. Comparison of the data on HCV in the present study with data from other parts of India showed a wide variation in the different centers. The higher prevalence of HCV among CRF patients and thalassaemics indicates the need for screening of the blood units for anti-HCV before transfusion to these high risk patients.Item Ultrasonographic diagnosis of haematometrocolpos in patients refusing vaginal examination.(1992-05-01) Agrawal, P K; Kumar, P; Jaiswal, S P
