RESUMO
Gastric varices and portal hypertensive gastropathy (PHG) are an important complication of both generalized and segmental portal hypertension. The natural history and risk factors for bleed from GV are not extensively studied as that for esophageal varices. Recently, effective therapy for gastric variceal bleed in form of tissue adhesives, balloon-occluded retrograde transvenous obliteration of gastric varices (BRTO) has been developed. Further advances are still needed regarding natural history, risk factors, bleeding, and mechanism of GV rupture.

BACKGROUND & OBJECTIVES: In India, horizontal transmission in early childhood has been shown to be a significant mode of transmission of hepatitis B virus (HBV). This prospective, cross-sectional study was undertaken to study the biochemical, serological and histological profile of incidentally detected asymptomatic HBsAg positive subjects (IDAHS) picked up at a tertiary care referral centre. METHODS: In 157 (M:F::123:34) HBsAg positive subjects, clinical, biochemical, virological and histological assessment was done. The histological activity index (HAI) of > 3 was considered as chronic hepatitis. Serum was tested for HBsAg, HBeAg, HBeAb, HBV DNA and alanine transaminase (ALT). RESULTS: Seventy (45%) subjects were HBeAg and 83 (53%) anti-HBe positive. While 71 per cent of the subjects with elevated ALT had an HAI > 3, only 36 per cent with normal ALT showed significant histological changes (P < 0.001). Significant histopathological lesions in the liver biopsy were seen in 92 (59%) subjects, with moderate to severe lesions in 14. IDAHS who were HBeAg +ve were more likely to have significant histological lesion than those who were anti-HBe +ve (P < 0.01). In the anti-HBe +ve group, 35 of 57 (61%) subjects for whom HBV-DNA was available, were HBV-DNA positive. Anti-HBe+ve, HBV-DNA+ ve IDAHS with elevated ALT were more likely to have chronic hepatitis vis-a-vis those subjects in this group who had a normal ALT (P < 0.001). INTERPRETATION & CONCLUSION: ALT is a reliable discriminant of significant histological lesion in IDAHS. The relatively young mean age of Anti-HBe +ve IDAHS suggests an early age of infection and hence, early seroconversion or mutant virus infection in this cohort. A significant proportion of these IDAHS have HBV-DNA positivity and HAI > 3. Our results clearly demonstrate ongoing liver disease in asymptomatic, so-called "HBV carriers". We propose that the term hepatitis B 'carrier' should be abandoned and replaced by 'chronic HBV infection'.

BACKGROUND: Pleural fluid cholesterol has been reported to be useful in distinguishing between transudative and exudative pleural effusion. However, the difference in lipid profile between tubercular and non-tubercular pleural effusion has not been studied. METHODS: The lipid profile of pleural fluid in 50 patients with exudative (25 tubercular and 25 non-tubercular) and 25 with transudative effusion was studied. The diagnosis was based on clinical criteria and/or a positive diagnosis from another site. RESULTS: The criteria that best identified an exudative pleural effusion were pleural fluid cholesterol > or = 60 mg/dl, pleural fluid to serum cholesterol ratio > or = 0.4, pleural fluid triglyceride > or = 40 mg/dl and pleural fluid to serum triglyceride ratio > or = 0.3. Pleural fluid cholesterol had a sensitivity of 88% and a specificity of 100% for exudates with an accuracy of 92%. Pleural fluid to serum cholesterol ratio had a sensitivity of 98% and a specificity of 84%. These results were superior to the criteria proposed by Light et al. (sensitivity 98% and specificity 80%). CONCLUSION: Pleural fluid cholesterol estimation is an effective and cost-efficient method of differentiating exudative from transudative pleural effusion. The lipid profile does not help in diagnosing tubercular effusion.

BACKGROUND: Nonalcoholic steatohepatitis (NASH) has often been described in obese women with diabetes and/or hyperlipidemia. We evaluated the clinical, biochemical and histological profile of NASH. METHODS: 52 patients with persistently elevated ALT (>40 IU/L) for >6 months with no history of significant alcohol consumption and negative serological work-up for hepatitis B and C and HIV were enrolled. Twenty-five patients were diagnosed as having NASH and their clinical, biochemical, and histological profile was evaluated. RESULTS: Of the 25 patients with NASH (mean age 33 years), 24 were men. Three were obese, seven had hyperlipidemia and two had impaired glucose tolerance. Thirteen patients presented with pain in the right hypochondrium, three with fatigue and weakness, and nine were asymptomatic. No patient had evidence of portal hypertension or liver cell failure. Mild elevation of ALT was the most common biochemical abnormality. Twenty-three of the 25 patients had ALT/AST ratio >1.0. Liver histology revealed macrovesicular steatosis in all, with mild inflammatory activity in the majority (70%). Fibrosis was seen in 12 patients-portal fibrosis in six, periportal fibrosis in three and bridging fibrosis in another three patients. None of the patients had features of cirrhosis. None of the factors was found to be associated with fibrosis except serum AST level, which was significantly higher in patients with fibrosis as compared to those without (89 [52] vs. 54 [18] IU/L; p<0.05). CONCLUSIONS: NASH is often seen in men, in the absence of obesity, diabetes and hyperlipidemia, and its severity is better assessed by liver histology than clinical assessment.

OBJECTIVES: Patients with alcoholic cirrhosis (AC) are frequently infected with hepatotropic viruses which could alter the clinical spectrum of the disease. We studied the seroprevalence of hepatitis B (HBV) and hepatitis C virus (HCV) and their impact on the clinical profile of patients with AC. METHODS: Two hundred and ten hospitalized patients of AC were studied and screened for markers of HBV and HCV infection. Clinical, biochemical and virological correlation was done. RESULTS: One hundred and forty (66.6%) patients had no viral infection Group I, 50 (23.8%) were positive for HBsAg Group II and 20 (9.5%) for anti-HCV Group III. All patients were males with comparable ages (43.9 years, 44 years and 45.9 years respectively). The amount of alcohol consumed by patients in Group III (130 +/- 115 g/d) was significantly less than Group II (204 +/- 130 g/d, P < 0.05) and Group I (281 +/- 188 g/d, p < 0.001). The duration of alcohol abuse was shorter in Group II and III, although not statistically significant. Presentation as jaundice was common in Group II and III (p < 0.05). The AST and ALT values (IU/L) were significantly higher in Group II (239 +/- 351, 197 +/- 266) and III (157 +/- 170, 86 +/- 52) than Group I (89 +/- 78, 66 +/- 54) (P < 0.05). The serum alkaline phosphatase (IU/L) was higher in Group III (349 +/- 223) as compared to Group II (263 +/- 186) and Group I (162 +/- 62) (P < 0.05). There was however, no difference in Child's grade or the discriminant function between the three groups of patients. CONCLUSIONS: (i) One-third of the hospitalized patients with AC are infected with HBV or HCV infection, (ii) these infections hasten clinical presentation of patients with alcoholic liver disease, with lesser amount of alcohol consumption and (iii) jaundice, raised ALT/AST and alkaline phosphatase are more common with superadded viral infection.

Complications of suppurative otitis media are common in developing world. Cholesteatoma has been implicated as the causative factor. We studied 76 cases of suppurative otitis media presented with complica tions and found that only 64% cases had cholesteatoma. Granulation were present in most of the cases of intracranial complications (16.68%).
RESUMO
BACKGROUND: Autoimmune hepatitis (AIH) is presumed to be rare in India. The present prospective study was carried out to determine the prevalence, clinical, biochemical and histological profile of patients with AIH in India. METHODS: Consecutive patients with chronic liver disease suspected to be AIH, were screened for antinuclear antibodies (ANA), antismooth muscle antibodies (ASMA), antimitochondrial antibody (AMA), and anti-liver kidney microsomal antibodies (anti-LKM-1). Serum protein electrophoresis and liver biopsy were done. Autoimmune hepatitis was diagnosed according to the International Autoimmune Hepatitis Group criteria. RESULTS: Fifty of 1358 (3.43%) patients with chronic liver disease were diagnosed as autoimmune liver disease; 39 with AIH, two with overlap syndrome, five with primary sclerosing cholangitis, and four with primary biliary cirrhosis. Twenty-nine patients were categorized as definite AIH and 10 as probable AIH. Autoimmune hepatitis was common in females (males : females 1:3), with a mean age of 31 +/- 17 years. Patients often presented with fatigue, jaundice and anorexia. Skin lesions (58%), joint symptoms (30%), and menstrual abnormalities (26%) were not uncommon. Mildly elevated alkaline phosphatase and hyper gamma globulinemia were seen in 78 and 91% patients, respectively. Eighty percent of patients were type I AIH, while 20% of cases remained unclassified. Histopathological changes included piecemeal necrosis (100%), plasma cell infiltration (91%), rosette formation (82%), and cirrhosis (76%). Overall mortality was 25% during a mean follow up of 15.7 +/- 17.0 months. CONCLUSIONS: Our results clearly demonstrate that: (i) AIH is not uncommon in India; and (ii) while the profile and spectrum of AIH resembles that seen in the West, Indian patients present late, often in a cirrhotic state.

BACKGROUND AND AIMS: Hepatotoxicity is a major side-effect of antitubercular drugs (ATD). As these drugs are metabolized in the liver, there is a theoretical risk of increased hepatotoxicity in patients with underlying chronic liver disease (CLD). Ofloxacin has antitubercular activity and has exclusive renal clearance. The aim was to study the efficacy and safety of an ofloxacin-based antitubercular regimen for treating tuberculosis in patients with underlying CLD. METHODS: Thirty-one cases were randomly assigned to two drug regimens using WHO dosage schedules: (i) regimen A (n = 15): isoniazid, rifampicin and ethambutol for 2 months, followed by isoniazid and rifampicin for a further 7 months; and (ii) regimen B (n = 16): isoniazid, pyrazinamide, ethambutol and ofloxacin for 2 months, followed by isoniazid, ethambutol and ofloxacin for a further 10 months. Hepatotoxicity was diagnosed if alanine aminotransferase/aspartate aminotransferase increased > fivefold from the baseline or to > 400 IU/L, or if bilirubin increased by > 2.5 mg/dL from the baseline. RESULTS: The response to ATD was achieved in all the patients who completed the therapy. Four (26.6%) patients on regimen A developed hepatotoxicity as compared to none on regimen B (P = 0.043). None of these patients could be restarted on ATD using the same regimen A because of the persistently deranged liver functions. CONCLUSIONS: In patients with tuberculosis who have underlying CLD: (i) an ofloxacin-based antitubercular regimen without rifampicin is as effective as a rifampicin-based regimen; and (ii) a combination of isoniazid with rifampicin is more hepatotoxic than a combination with ofloxacin and pyrazinamide.

Rhinoscleroma is a chronic granulomatous disease which involves upper respiratory tract. We undertook this study to find out the antibacterial effect of local acriflavin on Klebsiella rhinoscleromatis, as well as the disease rhinoscleroma. Antibiotic effect of acriflavin was studied on one of the isolate of Klebsiella rhinoscleromatis using whatman No.1 filter paper disc soaked in 2% and 5% acriflavin solution and was found sensitive. A total of 26 cases diagnosed clinically and histopathologically were studied. These patients were treated using 1%, 2% and 5% acriflavin ointment. The cure was 33%, 67% and 100% respectively. Details of response to acriflavin therapy and its adverse effect will be discussed. It is concluded that acriflavin can be used as a good alternative to systemic therapy for rhinoscleroma. As it can be prepared and applied easily and is not a financial burden on already poor patient.
RESUMO
BACKGROUND/AIMS: HBV-related chronic liver disease patients often present with hepatic decompensation and are not eligible for interferon therapy. Whether long-term lamivudine is effective in these patients was prospectively evaluated. METHODS: Eighteen patients with HBV-related decompensated cirrhosis, all with quantitative DNA +ve and 10 HBeAg +ve, were given lamivudine 150 mg/d. RESULTS: Each patient received at least 9 months (mean 17.9) of lamivudine. Three HBeAg+ve patients (30%) seroconverted to anti-HBe and one lost HBsAg during the follow-up. An improvement from baseline in the aspartate aminotransferase (130 vs. 72 IU/l, p<0.04); alanine aminotransferase (111 vs. 58 IU/l, p<0.01) and Child-Pugh score (8.3 vs 6.7, p<0.013) was seen. Lamivudine had no significant side-effects. HBV DNA became undetectable in all patients by 8 weeks of therapy. In three (17%) patients, HBV DNA again became positive at 9, 9 and 27 months. YMDD mutant was, however, detected in only one (6%). A significant reduction was noted in the morbidity and hospitalizations for complications of liver disease before and after starting lamivudine (1.5+/-0.7 vs. 0.6+/-0.7, p<0.002). CONCLUSIONS: In decompensated HBV-related cirrhosis, lamivudine: i) is effective in suppressing HBV DNA and seroconversion to anti-HBe (30%), ii) can achieve significant improvement in clinical and biochemical status of liver functions.
