Résumé

PURPOSE: To comprehensively study the possibility of autoimmune reactivity by hepatitis viruses B and C (HBV &HCV) in Indian chronic liver disease (CLD) patients. METHODS: One hundred and sixty histopathologically proven CLD cases and 100 matched controls were analysed for viral serology for HBV and HCV and autoimmune serology for antinuclear antibody (ANA), anti smooth muscle antibody (ASMA) and Liver kidney microsomal antibody (LKM) using standard immunofluorescence technique. RESULTS: 43.7% of cases were chronic hepatitis B while 16.2% were positive for HCV. CLD-B cases showed ANA positivity in 27.1% and ASMA positivity in 25.7%. CLD-C cases revealed 26.9%, 46.1% and 11.1% positivity for ANA, ASMA and LKM antibodies respectively. These rates and titres of autoantibodies were statistically significant (p=< 0.02) when compared with that of controls. Conclusions: Based on the pattern of autoantibody positivity, it could be concluded that chronic HBV infection may induce autoimmune hepatitis (AIH) type I and chronic HCV infection might trigger AIH - Type II in Indian CLD cases.

Résumé

OBJECTIVES: To evaluate the efficacy of second-generation ELISA (ELISA-2), third-generation ELISA (ELISA-3) and third-generation recombinant immunoblot assay (RIBA 3.0) for detection of antibodies to hepatitis C virus (anti-HCV) in comparison with reverse transcriptase-polymerase chain reaction (RT-PCR) to detect HCV RNA for the diagnosis of hepatitis C. METHODS: Sera of 108 patients with chronic liver disease (CLD) were analyzed by ELISA-2, ELISA-3, RIBA 3.0 and RT-PCR in the first part of the study; in the second part, sera of 105 patients with non-chronic liver disease were evaluated with ELISA-3, RIBA 3.0 and RT-PCR. RESULTS: In the CLD group, anti-HCV was positive in 4.6%, 14.8% and 16.6% by ELISA-2, ELISA-3 and RIBA 3.0, respectively. Among these anti-HCV positive cases, HCV RNA was positive in 100%, 58.9% and 64%, respectively. ELISA-2 did not give false-positive results, but missed substantial number of anti-HCV positive cases (p < 0.001). In the second group, anti-HCV was positive in 76.3% by ELISA-3 and 68.6% by RIBA 3.0 (p:ns). HCV-RNA was positive in 88.7% of ELISA- and RIBA-positive cases; in 60% of ELISA-positive, RIBA-indeterminate cases; and in 46.4% of ELISA-negative, RIBA-negative cases. CONCLUSIONS: ELISA-2 is not a suitable assay for routine screening. ELISA-3 was at par with RIBA 3.0 and it can be recommended for routine screening for anti-HCV. RT-PCR for HCV is of value in detecting early viremic, anti-HCV negative cases; this may be of importance in the treatment of hepatitis C.

Résumé

Three thousand nine hundred and twelve patients with cancer in various sites reporting to the out patient department were questioned for history of cancer among blood relatives. A positive history of cancer was obtained in 154 of whom 89 were male and 65 female. Thirty nine patients gave history of cancer among siblings and five gave history of cancer among spouses related by consanguneous marriage. The other 110 gave history of cancer among second and third generation relatives. Sixty one percent maternal relatives of the female patients had cancer as compared to only 33 percent of paternal relatives. This difference was not seen among male patients where there were about 45 percent of maternal and 47 paternal relatives giving history of cancer. Further it was found that 6 of 20 patients with cancer of the breast, 7 of 22 with stomach cancer and 4 of 12 with cervix cancer had blood relatives with the same type of cancer.

Résumé

Two hundred and forty four newly diagnosed hypertensives (cases) of age 40 years and above, attending the hypertensive clinic of the Government General Hospital during one year and three hundred and twelve normotensives (controls) belonging to the same age group and attending the outpatient department during the same period for other minor ailments formed the subjects for this case control study. There were 18 (7.4%) obese subjects among hypertensives and 6 (1.9%) among controls. In spite of these low proportions, there was a strong association between obesity and hypertension with an overall odds ratio of 4 and there appeared to be a significant increasing trend in the proportion of cases of hypertension (37%, 63%, 75%) observed according to the different grades (underweight or normal, overweight, obese) of nutrition.

Résumé

BACKGROUND: The acid suppressive abilities of H2 receptor antagonists and anticholinergics have been claimed to be additive. METHODS: A multicenter, double-blind, randomized trial comparing ranitidine (150 mg) plus propantheline bromide 15 mg at bedtime to ranitidine 300 mg alone at bedtime was conducted in 161 patients with endoscopically confirmed uncomplicated duodenal ulcer. RESULTS: After six weeks of therapy, ulcer healing rates in the two groups were comparable ie 80% in the combination group (ranitidine + propantheline) and 79.4% in the ranitidine group. Pain relief after one, two and four weeks of treatment was also comparable in the two groups. Side effects to drugs were minor and comparable in both the groups. CONCLUSION: A combination of 150 mg ranitidine and 15 mg propantheline bromide is as efficacious as 300 mg ranitidine in inducing healing of uncomplicated duodenal ulcers, with similar side-effects but at greatly reduced cost.
