Prospective randomized trial of endoscopic sclerotherapy versus variceal band ligation for esophageal varices: influence on gastropathy, gastric varices and variceal recurrence.

BACKGROUND/AIMS: Endoscopic variceal ligation and endoscopic sclerotherapy are both recommended for the prevention of variceal rebleeding. To compare their efficacy, their influence on gastric varices and the development of portal gastropathy, 95 patients with variceal bleeding were studied. METHODS: The patients were randomized to receive weekly endoscopic sclerotherapy using alcohol (n=48) or endoscopic variceal ligation (n=47). The endoscopic sclerotherapy and endoscopic variceal ligation groups were comparable in etiology, severity of liver disease and grade of varices. RESULTS: In the arrest of acute bleed, endoscopic sclerotherapy and endoscopic variceal ligation were comparable (86% vs. 80%, p=ns). Endoscopic variceal ligation as compared to endoscopic sclerotherapy, obliterated esophageal varices in fewer sessions (4.1+/-1.2 vs. 5.2+/-1.8, p<0.01) and a shorter time (4.4+/-1.3 vs. 6.9+/-3.4 wk, p<0.01). Three (6.4%) patients bled after endoscopic variceal ligation and 10 (20.8%) after endoscopic sclerotherapy (p<0.05). The actuarial percentage of variceal recurrence during a follow-up of 8.5+/-4.4 months, was higher after endoscopic variceal ligation than endoscopic sclerotherapy (28.7% vs 7.5%, p<0.05). Esophageal stricture formation after endoscopic sclerotherapy occurred in five (10.4%) patients, but in none after endoscopic variceal ligation. Significantly more patients developed gastropathy after endoscopic sclerotherapy than ligation (20.5% vs. 2.3%; p=0.02). Endoscopic sclerotherapy (52%) and endoscopic variceal ligation (59%) were equally effective in obliterating the lesser curve gastric varices. Six patients died: three in each group. CONCLUSIONS: (i) Endoscopic sclerotherapy and endoscopic variceal ligation were equally effective in controlling acute bleed; (ii) endoscopic ligation achieved variceal obliteration faster and in fewer treatment sessions; (iii) endoscopic variceal ligation had a significantly lower rate of development of portal gastropathy and rebleeding, (iv) while both techniques influenced gastric varices equally, there was significantly higher esophageal variceal recurrence after endoscopic variceal ligation than sclerotherapy.

Dietary and nutritional abnormalities in alcoholic liver disease: a comparison with chronic alcoholics without liver disease.

OBJECTIVE: To document the profile and role of malnutrition in alcoholic hepatitis, compared with chronic alcoholics and nonalcoholic chronic liver disease. METHODS: To this end, we studied 67 patients with alcoholic liver disease (ALD) (group I), 52 chronic alcoholics without histological evidence of liver disease (group II), 44 nonalcoholic cirrhotics (group III), and 52 healthy controls (group IV). Alcoholic and nonalcoholic calories were calculated and percentage dietary and nutritional deficiencies computed. Anthropometric indices, nitrogen balance, and immune status of the patients were assessed. RESULTS: Alcohol constituted about 48% of daily caloric intake in patients with ALD. The percentage mean intake of carbohydrate, protein, and energy was decreased in all three study groups compared with controls. The deficiencies were more pronounced in patients with severe than with moderate ALD. These deficiencies were more severe in the group III patients. Whereas body fat stores were maintained in groups I and II, reduction in lean body mass and serum transferrin was significant in patients in groups I and III. In group II patients compared to group I patients, the body mass index (19.9 +/- 4.0 vs. 22.3 +/- 3.4) and triceps skinfold thickness (6.1 +/- 4.8 vs. 10.2 +/- 5.6 mm) were significantly lower. CONCLUSIONS: 1) protein energy malnutrition is common in both alcoholic and nonalcoholic cirrhotics, but is more pronounced in the latter; 2) the degree and profile of malnutrition in chronic alcoholics and in alcoholic cirrhotics are comparable; 3) based on our results, we hypothesize that malnutrition may not play a primary role in the pathogenesis of ALD.

Efficacy of low-dose alpha interferon therapy in HBV-related chronic liver disease in Asian Indians: a randomized controlled trial.

BACKGROUND/AIMS: Interferon therapy has been shown to be effective in Western patients with chronic hepatitis due to hepatitis B viral infection, but not in Asian Chinese. Its efficacy in Asian Indian subjects with chronic HBV infection is not known. METHODS: Forty-one patients with HBV-related chronic liver disease received randomly either: (a) recombinant alpha 2b interferon (n = 20) 3 MIU, subcutaneously, three times a week for 4 months, or (b) no treatment (n = 21). Patients were followed up for 12 months after completion of therapy. RESULTS: In the interferon-treated group, complete response (loss of HBV-DNA and HBeAg) was significantly higher than spontaneous clearance in the control group (50% vs. 4.8% p < 0.05). Seroconversion to anti-HBe was seen in 35% of the treated and 4.8% of the control group (p < 0.05) at 4 months; it was noticeably higher in patients with chronic hepatitis than in those with cirrhosis. In the responders, alanine aminotransferase levels nearly normalized. One year after interferon therapy, HBeAg and HBV-DNA clearance was observed in 65% of patients, with HBsAg clearance in 15%. Reactivation was not seen in any patient. Side-effects were transient and minimal. CONCLUSION: Low-dose recombinant alpha interferon therapy is quite effective and safe in Asian Indians with chronic liver disease due to hepatitis B infection.

A randomized controlled trial of endoscopic variceal band ligation for primary prophylaxis of variceal bleeding.

OBJECTIVE: To assess the efficacy and safety of endoscopic variceal band ligation (EVL) for primary prophylaxis of variceal bleeding in patients with high-risk varices. DESIGN: A randomized, controlled trial. SETTING: Hospital based. SUBJECTS: Sixty-eight patients with portal hypertension with high-risk varices were randomized to undergo either EVL (n = 35) or no treatment (n = 33). INTERVENTIONS: Endoscopic variceal band ligation or no therapy. MAIN OUTCOME MEASURES: Probability of first variceal bleeding, probability of survival, variceal obliteration, complications of EVL. RESULTS: Oesophageal varices could be obliterated by EVL in 3.2 +/- 1.2 sessions within 4.9 +/- 2.2 weeks. Three (8.6%) patients in the EVL group and 13 (39.4%) in the control group bled during a mean follow-up of 14.1 +/- 5.0 months (range 2-22) (P < 0.01). The cumulative probability of the patients remaining free of bleeding was higher (P < 0.01) in the EVL group than the control. Variceal recurrence was seen in 10 (28.6%) patients and was managed by repeated EVL. None of the patients developed oesophageal stricture. Four (11.4%) patients in the EVL and eight (24.2%) in the control group died (P = NS). Bleed-related mortality was lower in the EVL than the control group (2.9% vs. 15.2%, P = 0.08). CONCLUSION: EVL significantly decreases the frequency of first variceal bleed. It should be evaluated further to see if bleeding-related mortality could be reduced in cirrhotics with high-risk varices who have not bled.

Frequency and clinical profile of precore and surface hepatitis B mutants in Asian-Indian patients with chronic liver disease.

BACKGROUND: Infection due to hepatitis B virus (HBV) could be due to wild or mutant (precore or surface) viruses. The prevalence and clinical profile of different viral forms in patients with chronic liver disease has not been established. METHODS: One hundred and twenty patients with histologically proven HBV-related chronic liver disease were studied. Patients with dual infection with HCV/HDV/HIV, past history of interferon therapy, or autoimmune hepatitis were excluded. Eighteen (15.5%) patients had the precore mutation (HBsAg +ve, HBeAg -ve/anti-HBe +ve, HBV DNA +ve), and 13 (10.8%) had the surface gene mutations (HBsAg -ve, HBeAg -ve, IgG anti-HBc, and HBV DNA +ve). The remaining 89 (74.2%) patients were infected with wild type HBV. The course of all patients with mutant forms and 41 of those with the wild type form was followed for a mean (+/- SD) of 4.4 +/- 2.4 yr. RESULTS: Compared with wild-type-infected patients, those with surface mutation were younger (39.9 +/- 14 vs. 30.1 +/- 12.4 yr, p < 0.05). Patients with precore mutations had a shorter illness than those with surface mutant (p < 0.01) and wild forms (p < 0.05). Histologically, patients with precore type had more active liver disease than wild type (39% vs. 15%, p < 0.05). Patients with precore mutations were always symptomatic, often presenting with ascites (67%) and jaundice (55%). Patients with surface mutant forms often presented with quiescent cirrhosis (77%) or cirrhosis with hepatoma (15%). CONCLUSIONS: One-fourth of HBV-related chronic liver disease in Asian Indians is attributable to mutant HBV forms. The presence of variant viruses alters the natural history of the disease, with the precore variance having a more aggressive course and the surface mutant, a more quiescent but unfavorable course, compared with the wild type.

Choledochal cysts--differences in children and adults.

Choledochal cysts in children and adults may behave differently. To identify these differences the records of 49 patients (22 children and 27 adults) who underwent surgery for choledochal cysts over a period of 7 years were analysed retrospectively. In two adult patients who had undergone a previous cholecystectomy an acquired malformation could not be excluded. Cholangitis was more common in adults. Choledochal cysts in children were predominantly Type I cystic lesions, whereas Type IV cysts were more common in adult patients. Anomalies of the pancreatic duct and associated hepatobiliary problems were seen exclusively in adults and the latter can make excision of the cyst more difficult and complicated. To prevent the development of complications choledochal cysts should be excised as soon as they are detected.

Low prevalence of hepatitis C viral infection in patients with non-alcoholic chronic liver disease in India.

To investigate the prevalence and profile of chronic liver disease due to hepatitis B (HBV) and C (HCV) infection in patients with non-alcoholic chronic liver disease in North India, 148 biopsy proven patients (73 with a history of transfusion and 75 non-transfused) were studied. Detection of hepatitis B included HBsAg, AntiHBc, and HBV DNA testing. Presence of HCV infection was investigated by EIA using second generation tests and confirmed by RIBA III and HCV RNA testing. Eighty three (56.1%) patients had cirrhosis related to hepatitis B, 13 (15.7%) of them had precore (HBeAg -ve, HBVDNA +ve) and 11 (13%) had surface (HBsAg-ve, IgM antiHBc-ve, HBVDNA +ve) mutation. Antibodies to HCV were found in 16 (10.8%) patients. Dual infection with HBV and HCV was seen in 20 (13.5%) patients. Twenty nine (19.5%) patients, had cryptogenic cirrhosis as none of the markers for HBV or HCV infection was positive. In conclusion, our results demonstrate that HBV was the most prevalent viral infection associated with chronic liver disease patients in North India. Prevalence of HCV infection was low. Studies to detect HBV mutants and other viruses should be done in patients with suspected cryptogenic cirrhosis of the liver.

The frequency and influence of gallbladder varices on gallbladder functions in patients with portal hypertension.

Gallbladder varices have been reported in patients with portal hypertension. The exact frequency and significance of these collaterals in patients with cirrhotic and noncirrhotic portal hypertension is not known. One hundred and two patients with portal hypertension [38 with cirrhosis, 29 with noncirrhotic portal fibrosis (NCPF) and 35 with extrahepatic portal vein obstruction (EHPVO)] and 25 healthy controls were studied. Gallbladder varices were seen at ultrasound as tortuous, dilated vessels in the wall or in the bed of the gallbladder. In 35 patients (19 patients with and 16 without gallbladder varices) and in 10 healthy controls, gallbladder functions were studied by determining fasting volume (FV) and then residual volume (RV) every 10 min over 1 h after giving a liquid meal of 420 k.cal. Ejection fraction (EF) was computed as a percentage by the formula: FV--RV/FV x 100. Twenty four (24%) patients had gallbladder varices: Five (13%) with cirrhosis, seven (24%) with NCPF, and 12 (34%) with EHPVO. FV in EHPVO patients was seen significantly more than in cirrhotics (31.6 +/- 15.4 vs 19.3 +/- 6.0 ml, p < 0.05). The RV and EF were not different in the three groups of patients compared with the controls. The EF was similar in patients with or without gallbladder varices (63.3 +/- 10.2% vs 64.6 +/- 10.4%). Gallbladder varices are often seen in portal hypertension, more often in EHPVO patients, and these collaterals cause some gallbladder stasis but do not impede gallbladder function and hence seem unlikely to contribute to gallstone formation.

High familial prevalence of gallstones in the first-degree relatives of gallstone patients.

Limited information is available on the prevalence of gallstones in the first-degree relatives of gallstone patients. Three groups of subjects were studied by real-time ultrasound examination: group A, 105 index gallstone patients (male/female; 20:85); group B, 330 first-degree relatives of index patients; group C, matched controls for group A (n = 105) and group B (n = 330) subjects. Dietary, anthropometric, and biochemical investigations were carried out. In 39 of 105 (37%) index cases, one or more additional family members had gallstones (positive-index case). The positive-index cases were younger than the remaining index cases (mean age, 33.1 +/- 14 vs. 44.5 +/- 13.1 years; P < .05). Fifty-one of 330 (15.5%) first-degree relatives had gallstones, nearly four and a half times (95% confidence interval [CI], 2.4 to 8.5) more often than in the matched control population (12 of 330 [3.6%]). Thirty-three of 51 (65%) positive relatives were women; mother (37.3%), sister (17.6%) or daughters (10%) to the index patients. There was no difference in the diet, physical activity, and serum lipid profile between the positive index patients and the remaining gallstone patients and positive relatives and their controls. Our results show that there is a strong familial predisposition for gallstone formation. Female relatives of young gallstone patients should be routinely screened for gallstones.

The prevalence and spectrum of colonic lesions in patients with cirrhotic and noncirrhotic portal hypertension.

Portal hypertension diffusely affects the gastrointestinal tract. The frequency and profile of distinct colonic mucosal lesions (portal colopathy) and rectal varices (RV; veins > 4 cm above the anal verge) is not well studied. Fifty consecutive patients with portal hypertension (25 with cirrhosis, 10 with noncirrhotic portal fibrosis [NCPF], and 15 with extrahepatic portal vein obstruction [EHPVO]) were assessed clinically and by upper and lower gastrointestinal (GI) endoscopy. Colorectal lesions were seen in 35 (70%) patients, significantly more often in bleeders than in nonbleeders. Rectal varices were detected in 22 (44%) patients; larger and more often seen in EHPVO (80%) than in cirrhosis (28%) and NCPF (30%) (P < .01) patients. Portal colopathy was seen in 26 (52%) patients, with nearly similar frequency in cirrhotics, NCPF, and EHPVO patients. Previous sclerotherapy or presence of gastric varices had little influence on the development of these lesions. An association (P < .01) was, however, seen between the presence of colopathy and portal gastropathy. Overt bleeding was seen in 8% and 4% of patients with RV and colopathy, respectively. In conclusion, our results demonstrate that colorectal lesions are present in about two thirds of patients with portal hypertension. Patients with portal hypertension and lower GI bleeding should be colonoscoped. Patients with extrahepatic portal vein obstruction may in turn benefit from baseline sigmoidoscopic examination to define the presence and size of rectal varices.

Effects of intravenous nitroglycerin and nitroglycerin and metoclopramide on intravariceal pressure: a double blind, randomized study.

OBJECTIVE: Effective and safe reduction of variceal pressure by pharmacological means. METHODS: Twenty patients with portal hypertension and large esophageal varices. Ten patients received i.v. nitroglycerin (300 micrograms-bolus) and an equal number received a combination of i.v. nitroglycerin (150 micrograms) and metoclopramide (20-mg bolus). Continuous measurement of variceal pressure and systemic hemodynamics was carried out. RESULTS: Compared with the baseline, the variceal pressure was reduced at 10 min after injection of 300 micrograms nitroglycerin (22.3 +/- 7.9 vs. 17.3 +/- 7 mm Hg, p, not significant); the percentage reduction was 23.5 +/- 15.8%. With the combination of low dose (150 micrograms) nitroglycerin and metoclopramide, variceal pressure significantly decreased from 23.1 +/- 4.7 to 15.9 +/- 5.9 mm Hg (p < 0.01) (a reduction of 29.5 +/- 24.1%). There was no significant alteration in the heart rate or mean arterial pressure with either regimen. CONCLUSIONS: Our results suggest that a combination of i.v. metoclopramide and low-dose nitroglycerin reduces variceal pressure more effectively than high-dose nitroglycerin used alone. This combination should be further evaluated in the control of acute variceal bleeding.
