Profile of alcoholic liver disease in an Indian hospital. A prospective analysis.

To study the profile of alcoholic liver disease in India, 144 consecutive, histologically diagnosed patients were prospectively studied. The patients were divided into those having alcoholic fatty liver (AFL) (Gr. I, n = 32), alcoholic hepatitis (AH) (Gr. II, n = 42) and alcoholic cirrhosis (AC) (Gr. III, n = 70) on the basis of their histological findings. All the patients were males, those with fatty liver being younger than those with cirrhosis. The amount of alcohol consumed by patients with AFL, AH and AC was not significantly different. Similarly, the duration of alcohol consumption was not significantly different between the three groups of patients. The clinical features of the patients were quite similar to those reported from the West, except that AH was relatively milder in our patients. Intake of poor quality country liquor was quite common (60%), but its use was not found to be associated with more severe liver injury as compared with the use of good quality foreign varieties of liquor.

Young v adult cirrhotics: a prospective, comparative analysis of the clinical profile, natural course and survival.

In order to assess the frequency and profile of cirrhosis in the young, 169 consecutive patients with cirrhosis were studied. Sixty three (37%) patients of less than or equal to 35 years age were defined as young and the remaining 106 (63%) patients (greater than 35 years) as adult cirrhotics. Men predominated significantly (p less than 0.01) in the young cirrhotic group. The aetiology, the frequency of positive hepatitis B markers and initial clinical presentation were similar in the two groups. During the follow up period (30.6 +/- 29.7 months for the young and 25.8 +/- 21.7 months for the adult group), except for abdominal distension and pedal oedema which occurred significantly more often in the adult compared with the young cirrhotics, no difference was noted in the two groups. Twenty seven (39.7%) deaths (40% as a result of hepatic failure and 52% due to variceal bleeding) occurred in the young and 47 (44.3%) deaths (63.8% because of hepatic failure and 26% because of variceal bleeding) occurred in the adult cirrhotics during the follow up (difference NS). The five year survival (61.9% v 55.7%) and the probability of survival within the same Child's grade of liver disease were comparable. In both the groups, however, the probability of survival was significantly higher in Child's A compared with Child's B and C and in Child's B compared with Child's C grade of liver disease. Survival was not influenced by sex of the patient and aetiology of cirrhosis. Results of this prospective study indicate that cirrhosis is not uncommon in young adults. The aetiology, clinical presentation, natural history of the disease and the survival rates in young cirrhotics do not differ significantly from adult cirrhotics.

Gastric secretion in cirrhosis and non-cirrhotic portal fibrosis.

Studies on basal and pentagastrin-stimulated gastric secretion were carried out in 20 patients with cirrhosis, 20 with non-cirrhotic portal fibrosis (NCPF) and 20 control subjects. There was no significant difference in the basal volume and acid output between the three groups. However, maximal volume and acid output were significantly lower in patients with cirrhosis and NCPF compared with the control group. There was no correlation between the acid secretion and the degree of hepatocellular dysfunction in patients with cirrhosis. Moreover, the gastric hyposection was as marked in the patients with NCPF as in those with cirrhosis, although the former did not suffer from any hepatic decompensation. It is concluded that gastric hyposecretion is not due to a derangement of hepatocyte function but may be secondary to portal hypertension and collateral circulation.

Bumetanide, spironolactone and a combination of the two, in the treatment of ascites due to liver disease. A prospective, controlled, randomized trial.

There are few studies available comparing the efficacy of loop and distal diuretics and a combination of the two groups, in the treatment of ascites due to liver disease. Thirty-seven nonazotemic cirrhotic patients with ascites were randomly allocated to receive for 2 weeks bumetanide (group A, n = 13), spironolactone (group B, n = 12) or a combination of the two drugs (group C, n = 12) after a 5-day stabilization period. The response to the treatment was 69, 42 and 83% in groups A, B and C, respectively; the difference was not significant. Hypokalemia was seen in 4 patients of group A and mild hyperkalemia in 2 patients of group B. Electrolyte disturbances were minimal in patients of group C. The response to diuretic treatment was prompt in groups A and C. It can be concluded that a combination of loop and distal diuretics is superior to a one-drug regimen in achieving a rapid and better diuretic response with fewer side effects.

Evaluation of the incidence and significance of the "mosaic pattern" in patients with cirrhosis, noncirrhotic portal fibrosis, and extrahepatic obstruction.

Mosaic pattern of gastric mucosa has been reported to be a sensitive and specific criterion for the diagnosis of portal hypertension and an important marker of nonvariceal upper gastrointestinal bleeding. So that the validity of this endoscopic sign could be assessed, 136 patients with portal hypertension, 25 chronic alcoholics without portal hypertension, and 366 controls were carefully endoscoped. Mosaic pattern was significantly (p less than 0.01) more common in portal hypertension patients (7.4%) than in controls (1.4%). It was not seen in chronic alcoholics. The incidence of mosaic pattern was 10.9% in cirrhotics, 2.9% in noncirrhotic portal fibrosis, and 5.4% in extrahepatic portal obstruction patients; the differences were not significant. Mosaic pattern was significantly (p less than 0.01) more often seen in postsclerotherapy (13.8%) than in presclerotherapy patients (2.6%). Bleeding from nonvariceal causes was uncommon, and was seen in only one patient (0.8%) showing mosaic pattern. Endoscopic gastric biopsies from areas showing mosaic pattern did not reveal any vascular abnormalities. In conclusion, gastric mucosal lesions are not very common in Indian patients with portal hypertension. In our experience, "mosaic pattern" is not a useful diagnostic feature in portal hypertension patients.

Ethanolamine oleate versus absolute alcohol as a variceal sclerosant: a prospective, randomized, controlled trial.

Forty-seven patients with esophageal variceal bleeding were randomly allocated to undergo sclerotherapy on a 3 weekly schedule with either 5% ethanolamine oleate (23 patients) or absolute alcohol (24 patients), in an attempt to compare the efficacy and safety of the two sclerosants. Sclerotherapy with absolute alcohol eradicated esophageal varices significantly earlier compared with ethanolamine oleate (12.9 +/- 5.2 vs 22.3 +/- 8.2 wk, respectively, p less than 0.001). The mean number of injection courses and the mean amount of sclerosant required for variceal obliteration was also significantly (p less than 0.001) less in the alcohol-injected group. Although the total number of rebleeding episodes were significantly (p less than 0.05) less in the alcohol-injected group, the frequency of rebleeding was not significantly different between the two groups (20.8% vs 30.4%, respectively, p greater than 0.05). Two (8.1%) patients died due to rebleeding in the ethanolamine-injected group, whereas in the alcohol group, none died. There was no significant difference in the frequency of complications with the two sclerosants. Besides the relative ease of rapid injection due to its aqueous nature, alcohol is readily available and relatively economical (total cost of sclerosant per patient; alcohol US $0.50, ethanolamine US $60). In conclusion, absolute alcohol appears to be a useful alternative to 5% ethanolamine oleate as a variceal sclerosant.

Significance of eosinophil and mast cell counts in rectal mucosa in ulcerative colitis. A prospective controlled study.

Eosinophil and mast cell counts were done in 44 patients with active ulcerative colitis, 10 patients with ulcerative colitis in remission, and 44 matched subjects with functional bowel disorder. Mean (+/- SD) rectal eosinophil counts (EC) per unit area were significantly high (P less than 0.01) in active ulcerative colitis (5.80 +/- 5.49) as compared with inactive disease (2.81 +/- 2.19) or controls (3.01 +/- 1.67). Eosinophil count was not significantly different in the acute stage between responder (6.36 +/- 5.95) and nonresponders (5.1 +/- 5.84) to medical treatment and was thus of little discriminatory and prognostic value. Mean (+/- SD) EC was reduced from 6.36 +/- 5.95 to 3.91 +/- 3.19 in responders after four weeks of medical treatment. There was little change in the EC with treatment in nonresponders. No correlation was seen between tissue eosinophils and clinical severity of ulcerative colitis. Mast cell count was not significantly different between patients with active ulcerative colitis, inactive disease, and controls and thus had little diagnostic or prognostic value. It can be concluded therefore, that EC in the rectal mucosa indicated activity but not severity of ulcerative colitis. A reduction in EC possibly indicated remission. Rectal EC, however, cannot correctly prognosticate the treatment response and outcome of the disease.

Relative efficacy and safety of absolute alcohol and 50% alcohol as variceal sclerosants.

Absolute alcohol and 50% alcohol were compared as sclerosants in 79 patients who underwent sclerotherapy for esophageal varices every 3 weeks with either of the solutions. Active variceal bleeding could be controlled more often (p less than 0.05) with absolute alcohol (93.3%) compared with 50% alcohol (53.8%). Variceal eradication could be achieved with absolute alcohol in a significantly shorter time with smaller amounts and fewer sclerotherapy sessions than with 50% alcohol. Except for a higher incidence of retrosternal pain and fever noted with the use of absolute alcohol, there was no significant difference in the incidence of various complications, rebleeding rate, or mortality between the two sclerosants. Absolute alcohol is a more effective and equally safe sclerosant compared with 50% alcohol.

Possible HLA influence in governing susceptibility to non-cirrhotic portal fibrosis.

Forty-eight unrelated North Indian patients with non-cirrhotic portal fibrosis were studied for the distribution of HLA-A, B and DR antigens. No significant differences were observed in the distribution of HLA-A and B locus antigens. In the DR locus, the frequency of DR3 was significantly increased in the patients as compared to the controls (71.7% vs 26.1%, X2 = 25.3), while HLA-DR2 was significantly reduced (X2 = 11.3). Another striking observation was the presence of DR7 in all males negative for HLA-DR3. The results suggest an autoimmune pathogenesis of the disease and that susceptibility to non-cirrhotic portal fibrosis may be HLA class II mediated, with HLA-DR3 influencing susceptibility and DR2 conferring protection. Other genetic factors are also involved.

Biliary lipid composition in patients with non-cirrhotic portal fibrosis--a comparison with compensated cirrhosis of the liver.

Patients with non-cirrhotic portal fibrosis (NCPF) are known to have mild hepatic functional abnormalities. To study the biliary lipid composition in these patients, duodenal bile was collected from 18 patients with NCPF, 15 patients with non-alcoholic compensated cirrhosis of the liver and 18 matched, non-obese, healthy control subjects. There were no significant differences in the mean (+/- SD) concentrations of cholesterol, phospholipids and bile acids in patients with NCPF and healthy controls. On the other hand, patients with cirrhosis had significantly lower concentrations of all the three biliary lipids as compared with the NCPF patients and controls (p less than 0.05). The cholesterol solubilizing capacity of the bile was the same in NCPF patients, cirrhotics and controls. It is concluded that the relative proportions of the three biliary lipids remain unchanged in patients with NCPF despite mild hepatic derangement.

Optimum dosage of ispaghula husk in patients with irritable bowel syndrome: correlation of symptom relief with whole gut transit time and stool weight.

To determine the optimum dose of ispaghula husk in patients with irritable bowel syndrome (IBS) and to assess the correlation, if any between the relief in patients' symptoms and the whole gut transit time, and the increase in stool weight, a two part study was carried out. In part 1, 14 male patients were given ispaghula husk in increasing doses of 10 g, 20 g, and 30 g a day for a duration of 17 days each (14 days of study period + three days of stool collection). Ten patients completed the trial. The symptom score improved significantly with all the three doses of ispaghula. Both 20 g and 30 g doses of ispaghula were superior to the 10 g dose but there was no significant difference between the 20 g and 30 g doses. There was a significant (p less than 0.001) increase in the daily stool weight with 10 g dose of fibre with further significant increases with the 20 g and 30 g doses. A positive correlation was seen between the improvement in the symptom score and the increase in stool weight with the 10 g dose of ispaghula but not with the 20 g and 30 g doses. Whole gut transit time remained fairly constant throughout the study period and there was no relationship with either the dose of ispaghula, the alteration in stool weight, or the improvement in the patients symptoms. Ten patients completed part 2 of the study in which ispaghula husk was given in the same dose (10 g, 20 g, and 30 g) but in a random order and with a "washout" period of one week between individual doses. Again all the three doses of ispaghula produced a significant improvement in the symptoms; 20 g and 30 g doses were equally effective and both were significantly superior to the 10 g dose. Assessed individually, all the three symptoms improved significantly; improvement in constipation and pain abdomen was more pronounced than diarrhoea. It is concluded that the optimum dose of ispaghula husk in irritable bowel syndrome is 20 g per day. There is some correlation between the increase in stool weight and the improvement in symptom score but the whole gut transit time remains unchanged despite alterations in stool weight and patients' symptoms.

Measurement and correlation of wedged hepatic, intrahepatic, intrasplenic and intravariceal pressures in patients with cirrhosis of liver and non-cirrhotic portal fibrosis.

In order to examine the relationship of various haemodynamic parameters in two different liver diseases, 10 patients with cirrhosis of liver and 14 patients with non-cirrhotic portal fibrosis were studied. In cirrhotics, mean (+/- SD) wedged hepatic (25.8 +/- 6.4 mmHg), intrahepatic (24.5 +/- 6.2 mmHg) and intrasplenic (25.0 +/- 5.6 mmHg) pressures correlated significantly (p less than 0.001) with intravariceal (25.2 +/- 6.7) pressure measurements. In patients with NCPF, mean (+/- SD) wedged hepatic (9.1 +/- 3.7 mmHg) and intraphepatic (15.4 +/- 5.8 mmHg) pressures were significantly (p less than 0.01) lower than the intrasplenic (24.5 +/- 4.2 mmHg) and intravariceal (23.96 +/- 5.6 mmHg) pressures. Two independent pressure gradients, one between intrasplenic and intrahepatic pressure (8.9 +/- 6.5 mmHg) and another between intrahepatic and wedged hepatic venous pressure (6.2 +/- 5.6 mmHg) were seen in non-cirrhotic portal fibrosis patients, indicating the likelihood of both pre- and perisinusoidal resistance to flow of portal venous blood in these patients. A highly significant (p less than 0.001) correlation between intravariceal and intrasplenic pressures was found in patients with cirrhosis of liver (r = 0.93), as well as in patients with non-cirrhotic portal fibrosis (r = 0.85). No correlation was found between the size of oesophageal varices and wedged hepatic and intrahepatic pressures. Patients with grade 4 varices had significantly higher intravariceal (p less than 0.01) and intrasplenic (p less than 0.05) pressure than patients with grade 2 varices. It can be concluded that intravariceal pressure is representative of portal pressure in patients with cirrhosis of liver as well as in non-cirrhotic portal fibrosis patients and it can be recommended as the single haemodynamic investigation in patients with portal hypertension and oesophageal varices.

Intravariceal versus paravariceal sclerotherapy: a prospective, controlled, randomised trial.

Fifty four consecutive patients with oesophageal variceal bleeding were randomised to undergo intravariceal (28 patients) or paravariceal (26 patients) sclerotherapy, every three weeks. Intravariceal technique was found significantly (p less than 0.01) more effective in controlling active variceal bleeding than the paravariceal technique (91% v 18.7% respectively). The mean (+/- SD) time taken for variceal eradication by intravariceal sclerotherapy (15.4 +/- 5.3 weeks) was significantly (p less than 0.001) less than paravariceal (26.8 +/- 6.6 weeks) technique. The number of sclerotherapy sessions needed with intravariceal technique were also significantly less. Rebleeding was seen in 38.5% patients after para and 14.3% after intravariceal injections (NS). Except for retrosternal pain, which occurred more often (p less than 0.01) with paravariceal technique, there was no difference in the incidence of other complications or mortality between the two groups. Variceal recurrence was seen in seven patients (25%) in the intra and one (3.9%) patient in the paravariceal group (p less than 0.01) after a mean follow up of 29.4 +/- 9.1 weeks. Intravariceal sclerotherapy was superior to paravariceal in the control of active variceal bleeding and for total variceal obliteration, but was associated with a higher variceal recurrence.

Familial aggregation in noncirrhotic portal fibrosis: a report of four families.

Noncirrhotic portal fibrosis is a common cause of portal hypertension in India. We report four families with more than one member afflicted with this disorder. Six of the seven (85.5%) patients in whom HLA studies were carried out were HLA-DR 3 positive. The possibility of an immunogenetic basis of noncirrhotic portal fibrosis should be investigated further.
