Celiac disease (CD) has been associated with several genetic and immune disorders, but association between CD and hereditary fructose intolerance (HFI) is extremely rare. HFI is an autosomal recessive disease caused by catalytic deficiency of aldolase B (fructose-1,6-bisphosphate aldolase). We report the case of a 5-year-old boy suffering from CD, admitted with an initial diagnosis of Reye's-like syndrome. He presented with episodic unconsciousness, seizures, hypoglycemia, hepatomegaly and abnormal liver function. The patient has been on an exclusion diet for three years, but he still had symptoms: stunting, hepatomegaly, high transaminases, but tissue transglutaminase antibodies were negative. Liver biopsy showed hepatic steatosis and mitochondrial damage. The dietary history showed an aversion to fruits, vegetables and sweet-tasting foods. The fructose tolerance test was positive, revealing the diagnostic of hereditary fructose intolerance. Appropriate dietary management and precautions were recommended. The patient has been symptom-free and exhibited normal growth and development until 10 years of age.

Hepatic adenomatosis is a benign disease defined as the presence of multiple adenomas in a normal liver. It is an uncommon condition and there are less than a hundred reported cases in the literature. The etiology is unknown, although it has been associated with the use of oral contraceptives, anabolic steroids, certain storage diseases and some genetic mutations linked to maturity onset diabetes of the young. The coexistence of hepatic adenomatosis and nonalcoholic steatohepatitis has been recently described in two patients suffering from metabolic syndrome. This association is particularly interesting due to the growing prevalence of nonalcoholic fatty liver disease in developed countries and the possibility of a common causal pathway. We report the case of a young woman with fructosemia and hepatic steatosis; multiple hepatic adenomas associated to steatohepatitis lesions were also found during clinical follow-up. The possible implications are discussed.

Increasing evidence suggests a role for excessive intake of fructose in the Western diet as a contributor to the current epidemics of metabolic syndrome and obesity. Hereditary fructose intolerance (HFI) is a difficult and potentially lethal orphan disease associated with impaired fructose metabolism. In HFI, the deficiency of aldolase B results in the accumulation of intracellular phosphorylated fructose, leading to phosphate sequestration and depletion, increased adenosine triphosphate (ATP) turnover, and a plethora of conditions that lead to clinical manifestations such as fatty liver, hyperuricemia, Fanconi syndrome, and severe hypoglycemia. Unfortunately, there is currently no treatment for HFI, and avoiding sugar and fructose has become challenging in our society. In this report, through use of genetically modified mice and pharmacological inhibitors, we demonstrate that the absence or inhibition of ketohexokinase (Khk), an enzyme upstream of aldolase B, is sufficient to prevent hypoglycemia and liver and intestinal injury associated with HFI. Herein we provide evidence for the first time to our knowledge of a potential therapeutic approach for HFI. Mechanistically, our studies suggest that it is the inhibition of the Khk C isoform, not the A isoform, that protects animals from HFI.
