Nine women with symptomatic precirrhotic primary biliary cirrhosis have been treated with oral pulse methotrexate, 15 mg/wk, for 12-34 months. Three women had pruritus, two fatigue, and four pruritus and fatigue. Itching disappeared and fatigue lessened or disappeared in all within 4-11 months after starting methotrexate. All who itched were able to discontinue cholestyramine (five) or antihistamines (two). Biochemical tests of liver function improved in all patients and then worsened in three when methotrexate was discontinued or the dose lowered. Mean serum alkaline phosphatase decreased from 471 to 171 U/L (P less than 0.01), serum bilirubin from 0.99 to 0.59 mg/dL (P less than 0.05), and serum alanine aminotransferase from 132 to 61 U/L (P = 0.02), and serum cholesterol fell from 265 to 213 mg/dL (NS). The decrease in serum cholesterol was significant, P = 0.05, if data were used just from the six women whose baseline serum cholesterol levels were elevated. Serum albumin remained normal in all. The serum bilirubin levels became normal in three of four patients with elevated levels. The serum alkaline phosphatase levels became normal in four patients and the alanine aminotransferase levels in three. Liver histology improved in five patients and was stable in the remaining four based on a quantitative evaluation of coded liver biopsy specimens. The improvement in histology was primarily due to decreased portal inflammation and bile duct injury. The titer of antimitochondrial antibody decreased in seven patients. The data suggest that methotrexate may be effective treatment for precirrhotic primary biliary cirrhosis. Controlled trials are needed to evaluate long-term efficacy and toxicity.

Thirty-five patients with primary biliary cirrhosis were seen between 1974 and 1989. The median mean age at presentation was 53 years (range: 30-77) and the female to male ratio was 7.8:1. Thirteen (37%) were asymptomatic and nine (26%) had associated auto-immune disorders. Pruritus and hepatomegaly were present in half of the patients. Advanced histological stages of disease (Stages 3 and 4) were present in 57% of patients. The median period of follow-up was 5 years (range: 0.1-20). Twelve patients died, nine from hepatic causes and three from non-hepatic causes. One has undergone liver transplantation. A Kaplan-Meier curve estimated the median survival to be 11 years. Asymptomatic patients developed progressive disease and survival was similar to that of symptomatic patients. Using Cox's proportional hazards model, age, serum bilirubin and serum albumin were found to be independent prognostic variables correlating with reduced survival.

During her 26th week of pregnancy a 20-year-old woman developed generalized pruritus, urticaria, flushing, tinnitus, and tachycardia during plasmapheresis with 5% human serum albumin (HSA) as adjunctive treatment for anti-Kell isoimmunization. The reaction was controlled with intravenous diphenhydramine. Despite pretreatment with diphenhydramine and betamethasone a subsequent attempt to perform plasmapheresis with infusion of 5% HSA resulted in a more severe reaction which progressed to respiratory distress. Intradermal skin testing with 5% HSA produced a 9 x 11-mm wheal and 17 x 21-mm erythema at 15 minutes. An enzyme-linked immunoassay was positive for IgE antibody to 5% HSA before and after dialysis for removal of Na caprylate. These results are consistent with an IgE-mediated basis for this patient's reaction to HSA.

The effect of meclofenamate on urinary protein excretion, level of serum albumin, and renal function was studied prospectively in 30 patients with corticosteroid-resistant severe nephrotic syndrome: 16 with focal segmental glomerulosclerosis, 12 with membranous glomerulopathy, and 2 with minimal-lesion nephropathy. Seventeen patients had a 40% or more reduction in urinary protein excretion ("responders"), and the decrease continued during long-term treatment. Meclofenamate therapy was discontinued after 2 months in eight "nonresponders" and in five other patients because of side effects (progressive increase in the level of serum creatinine in two, diarrhea in two, and pruritus in one). In responders, we recorded the following findings (mean +/- SD): urinary protein excretion decreased from 13.0 +/- 5.2 g/24 h to 7.2 +/- 3.5 g/24 h in 2 to 4 weeks and continued to decrease to 4.1 +/- 1.4 g/24 h at the time of the last follow-up study (median duration, 12 months; range, 6 to 36 months; P less than 0.01, 2 to 4 weeks versus later follow-up); the level of serum albumin increased from 1.9 +/- 0.5 g/dl to 2.9 +/- 0.7 g/dl (P less than 0.001) in 2 to 4 weeks; the level of serum cholesterol decreased from 413 +/- 125 mg/dl to 346 +/- 114 mg/dl (P less than 0.005) at the time of the last follow-up examination; and renal function remained unchanged from the baseline study to the follow-up study (serum creatinine 1.5 +/- 0.5 mg/dl versus 1.6 +/- 0.4 mg/dl and glomerular filtration rate 60.5 +/- 29.2 ml/min per 1.7 m2 versus 64.1 +/- 25.5 ml/min per 1.7 m2).(ABSTRACT TRUNCATED AT 250 WORDS)

Mild abnormalities of liver function tests are frequently seen in pregnancy but return to normal after delivery. A raised serum alkaline phosphatase is common, along with a decline in the serum albumin, but the aminotransferases remain within normal limits. The physician must interpret abnormal liver function tests in pregnancy with these changes in mind, but most liver diseases in pregnancy result in more marked alterations. Viral hepatitis is the most common cause of jaundice in pregnancy, and the maternal prognosis is generally good. Perinatal transmission of hepatitis B virus is likely when the mother is positive for HBsAg. Concurrent administration of hepatitis B vaccine and HBIG to the infant has an efficacy of 90 per cent in preventing transmission to the infant. ICP is the second most common cause of jaundice in pregnancy. The condition is generally benign, although maternal and fetal mortality occasionally result, probably due to premature delivery and the bleeding tendency of cholestatic patients. Vitamin K administration may correct the coagulopathy, and cholestyramine is effective in controlling pruritus. AFLP is rare but carries a high mortality rate for both the mother and the fetus. Early diagnosis, correction of the coagulopathy, and prompt delivery may improve the outcome significantly. Patients with cirrhosis have reduced fertility, and in those who become pregnant, fetal loss is high. The effect of pregnancy or hepatocellular function is variable, but, when evidence of liver failure is present in the first trimester, termination should be considered. Variceal size and the risk of bleeding may be assessed by endoscopy. Pregnant cirrhotic patients with large esophageal varices and a history of bleeding can undergo shunt surgery. Conservative management may be appropriate for patients with small varices and no history of bleeding.

Two female patients with grade IV primary biliary cirrhosis, untractable pruritus, arthralgias and xanthomatous neuropathy in one case, underwent long term plasmapheresis for 30 months (on a continuous centrifugation cell separator) and 18 months (on capillary plasma filters). Plasma exchange were performed monthly and substitution achieved by diluted human serum albumin. No major side effect occurred. Pruritus, arthralgias and xanthomatous neuropathy greatly improved or even disappeared. The plasma levels of transaminases, albumin, globulin and clotting factors were stable, alkaline phosphatases slightly diminished. Bilirubin, after an initial fall at 6 months, increased again. Cholesterol stabilized at near normal values. Bile acids blood levels decreased in both cases.

A survey of vitamin D status in 152 patients with chronic gastrointestinal conditions and 104 patients with chronic liver diseases is presented. Mild deficiency was common and severe deficiency, as judged by plasma 25-OHD levels less than 8 nmol/l, was encountered in every disease category tested. In the gastrointestinal disease patients, deficiency was significantly more common in patients following gastroenterostomy than other gastric surgery, in patients with active Crohn's disease than in those with inactive disease and in patients with chronic pancreatitis or pancreatic carcinoma with cholestatic features than in those without cholestatic features. Deficiency was as common in patients with Crohn's disease who had not been treated surgically as in those who had. There was no significant correlation between plasma 25-OHD levels and any laboratory index of malabsorption or malnutrition except for serum albumin in the gastric surgery patients, haemoglobin and ESR in the Crohn's disease patients and albumin and vitamin E in the group of patients with gastrointestinal disorders taken as a whole. In the chronic liver disease patients, those with late primary biliary cirrhosis had lower plasma 25-OHD levels than those with histological Stage I and II disease who all had normal levels, and those with pruritus and jaundice were more commonly severely deficient. Whatever the underlying disease process, patients with other coincidental medical conditions were much more likely to be deficient as were patients with cholestasis. Evidence of secondary hyperparathyroidism and osteomalacia on bone histology indicated the clinical relevance of the vitamin D deficiency. This study showed no relationship between abnormal plasma vitamin D binding protein levels and vitamin deficiency.

Acid anhydrides are low-molecular-weight chemicals known to cause respiratory irritancy and allergy. Skin allergy has on rare occasions been reported. 2 workers contracted hives and itching on uncovered skin after 2 months exposure to methyltetrahydrophthalic anhydride (MTHPA) and methylhexahydrophthalic anhydride (MHHPA), to which they had airborne exposure. Later, the patients also developed conjunctivitis, rhinitis, sore throat, cough or asthma. In addition to MTHPA, 1 worker was also exposed to unsaturated polyester resin (UP). Both patients' immediate allergy to MTHPA and MHHPA was verified by positive prick tests to MTHPA and MHHPA, conjugated with human serum albumin (HSA), and positive radioallergosorbent tests (RASTs) to these anhydrides. On prick testing, both patients also reacted to a phthalic anhydride (PA)-HSA-conjugate and 1 of the patients to UP-HSA-conjugate. Specific immediate allergy to UP was shown by RAST. RAST inhibition with MTHPA, MHHPA and UP-resin conjugates confirmed IgE-mediated allergy and cross-reactivity between anhydrides. Our patients had developed airborne contact urticaria caused by phthalic anhydrides, in addition to respiratory allergy. Phthalic anhydride contained in the UP resin was possibly responsible for the immediate reaction of the skin.

A 33-year-old woman without history of previous atopic diseases or drug allergies developed a severe anaphylactic reaction with asthma, vomiting, itching, generalized urticaria, and angioedema during artificial insemination with her husband's sperm. The sperm-processing medium contained bovine serum albumin (BSA). Skin prick test and RAST demonstrated an IgE-mediated hypersensitivity to BSA as well as a polyvalent atopic sensitization to pollens, animal danders, cow's milk, beef, pork, and mutton. SDS-PAGE studies indicated serum albumin to be the appropriate allergen with a high degree of cross-reactivity between serum albumin from different animal species. Artificial insemination with fluid containing potential allergens can, therefore, represent an unnecessary risk for atopic females, even in the absence of prior clinical symptoms of allergic diseases. Preoperative testing with the medium is recommended.

Nineteen patients treated by continuous ambulatory peritoneal dialysis (CAPD) were studied according to clinical outcome parameters: insomnia, asthenia, pruritus, arterial hypertension, anorexia, nausea and/or vomiting, anemia, and rate of hospitalization. Using clinical scores, three groups were defined: poor clinical outcome (P), intermediate (I), and good (G). The quantity of treatment by PD was evaluated monthly with urea kinetic tests (weekly Kt/V, weekly urea clearance/1.73 m2 of body surface area (BSA), index of dialysis by Teehan), and with the weekly creatinine clearance/1.73 m2 of BSA. The metabolic index was analyzed: normalized protein catabolic rate (NPCR), serum albumin (Alb) and prealbumin, and reabsorption of glucose. There was good correlation between clinical scores and quantity of dialysis. The Alb was lower in group P. Group G was differentiated from group I and from group P by quantification tests and NPCR, with lower levels as follows: weekly Kt/V = 2.06, urea clearance 70 L/week/1.73 m2, index of dialysis = 0.87, and creatinine clearance = 60 L/week/1.73 m2. We conclude that the qualitative clinical approach is not sufficient to predict deleterious signs, and the quantitative approach is predictive of the good clinical outcome and good nutritional status. We think that levels proposed to now are insufficient, and we suggest the following: weekly urea clearance > 70 L, weekly Kt/V > 2, weekly creatinine clearance > 60 L, and index of dialysis > 0.85.
