Prevalence of gallstones in patients with primary immunoglobulin deficiency

Abstract

In the early 1970s an increased prevalence of gallstones was reported in adults and children with immunoglobulin deficiency. As the advent of ultrasonography has largely changed the diagnostic approach to gallstones, we have reevaluated the prevalence of cholelithiasis in a group including 37 patients with common variable immunodeficiency and seven patients with other forms of primary immunodeficiency. All patients were receiving intravenous gammaglobulin replacement since 1983 or, in more recent cases, soon after the diagnosis was made, and therefore had relatively few infections. All patients underwent a hepatobiliary ultrasonogram and blood sampling. Data were compared, after age and sex standardization, with those obtained by the GREPCO in a free-living population of 1239 men and 1081 women. Only two women with immunoglobulin deficiency had gallstones. One of these was obese and had had one pregnancy. Both were asymptomatic. None of the patients studied had a history of cholecystectomy or evidence of biliary sludge. Thus, the observed prevalence rates of gallstone disease were 8.7% in women and 0% in males, respectively, against expected values of 9.5% and 3.2%. Immunodeficient patients expressed several putative risk factors for gallstones in the low range (body mass index, total and HDL cholesterol, and blood glucose in both sexes, and triglycerides in men). We conclude that gallstone disease is not more frequent in patients with immunodeficiency syndromes undergoing immunoglobulin therapy than in the general population.
