Multiple electrolytes imbalances in a patient with inflammatory bowel disease associated with vitamin D deficiency: a case report.

BACKGROUND: Inflammatory bowel disease involves chronic inflammation and ulceration, primarily Crohn's disease and ulcerative colitis. The prevalence of inflammatory bowel disease is rising in industrialized countries. We describe the case of a patient with inflammatory bowel disease and multiple electrolyte disturbances that emphasize the link between a vitamin D deficiency and electrolyte imbalances. CASE: An 86-year-old Japanese man with severe hypocalcemia, hypophosphatemia, hypokalemia, and hypomagnesemia was referred to the gastroenterology and hepatology department our university hospital for severe diarrhea and abdominal pain. Based on clinical symptoms and biochemical and endoscopic findings, Crohn's disease, intestinal Behçet's disease, and intestinal tuberculosis were considered as differential diagnoses, but a final diagnosis was not reached. Prednisolone, azathioprine, and metronidazole were administered, and no apparent electrolyte abnormality was observed at the patient's admission to our hospital. On the 80th hospital day, marked hypocalcemia, hypophosphatemia, hypokalemia, and hypomagnesemia were noted and prolonged, despite daily supplementation with Ca and inorganic P. At his consultation with our department, we observed decreased fractional excretion of Ca, tubular reabsorption of phosphate, fractional excretion of K, and fractional excretion of Mg, suggesting the depletion of vitamin D and extrarenal wasting of K and Mg. The patient's serum Ca and inorganic P were quickly elevated in response to treatment with an active form of vitamin D, and his serum levels of K and Mg were restored to the normal range by an intravenous administration of K and Mg. A vitamin D deficiency is not rare in inflammatory bowel disease and is caused primarily by the decreased intestinal absorption of vitamin D. In the management of electrolyte imbalances in patients with inflammatory bowel disease, clinicians must consider the possible development of vitamin D deficiency-related disorders. CONCLUSION: Vitamin D deficiency in entero-Behçet's disease leads to severe hypocalcemia and hypophosphatemia, highlighting the importance of awareness in management.

Japanese herbal medicine Inchin-ko-to as a therapeutic drug for liver fibrosis.

BACKGROUND/AIMS: Inchin-ko-to (TJ-135) is an herbal medicine used in Japan for treatment of icteric patients with cirrhosis. Its efficacy as an anti-fibrogenic drug was evaluated in relation to stellate cell activation. METHODS/RESULTS: Liver fibrosis was induced in rats by repeated injections of carbon tetrachloride (CCl4) or pig-serum. Oral administration of TJ-135 improved the mortality of rats given CCl4 with reduced extents of liver necrosis and fibrosis. Similar improvement of liver fibrosis was found in rats given pig-serum showing no liver necrosis. DNA synthesis of stellate cells activated in vitro after isolation from normal rat liver was decreased by culture with TJ-135 in a dose-related manner, accompanied by decreased smooth muscle alpha actin expression and contractility. Such attenuation was not found in the cells cultured with geniposide, an iridoid compound of TJ-135, but genipin, an aglycone of geniposide formed in the gut by action of bacterial flora, markedly decreased stellate cell activation without affecting synthesis of proteins other than collagen. CONCLUSIONS: TJ-135 may be useful for treatment of liver fibrosis and portal hypertension through suppression of activated hepatic stellate cell function by genipin, an absorbed form of its component.
