introduced the term ‘collagenous sprue’ in a report in the New England Journal

of Medicine in 1970 in which they described an individual Venetoclax manufacturer with malabsorption who was initially thought to have celiac disease but failed to respond to a gluten-free diet (GFD). Traditional thinking is that collagenous sprue is a complication of celiac disease. However, many patients with collagenous sprue have no evidence of celiac disease and collagenous sprue may represent the final result of a mucosal insult other than gluten sensitivity. The etiology of collagenous sprue is unknown but immune-mediated mechanisms are likely given initial responses to immunosuppressive therapy. Regardless of the etiology, collagenous sprue is thought to portend a poor prognosis with severe morbidity and mortality. Our patient was started on budesonide 9 mg daily and after three days had a complete resolution of diarrhea. The budesonide was subsequently tapered with a recurrence of diarrhea at budesonide 3 mg daily. She has been maintained on budesonide 6 mg daily without adverse sequelae. Clinical improvement on a GFD is an important component of diagnosing celiac disease. Lack of response to a GFD should raise the possibility of

alternative diagnoses and small bowel biopsies should then U0126 solubility dmso be reviewed by an expert pathologist to exclude other diagnoses. Duodenal intraepithelial lymphocytosis and villous atrophy may occur in other small bowel disorders including collagenous sprue. Contributed by “
“A previously healthy 29-year-old woman of Spanish origin presented with a 1-month history of right upper quadrant pain associated with fever and night sweats. The physical examination demonstrated a temperature of 38.5°C,

a normal blood pressure, a normal heart rate, and mild right upper quadrant tenderness with no peritoneal signs. Laboratory tests showed a slightly raised white blood cell count of 12,000/mm3 with a normal differential count and a C-reactive protein level of 230 mg/L. Liver function tests were normal. The abdominal computed tomography (CT) scan showed a hypodense lesion in the right hepatic lobe with a central calcified deposit (Fig. 1). The blood culture and serological tests for hydatidosis and amebiasis were negative. A definite Buspirone HCl diagnosis was made by a positive polymerase chain reaction test for Brucella melitensis in the abscess fluid (the abscess fluid culture was negative). The patient was initially managed by CT-guided percutaneous drainage and a combination of doxycycline (100 mg/day by mouth) and rifampin (600 mg/day by mouth). A laparoscopic liver exploration was subsequently performed to improve drainage and to remove the calcified deposit (Fig. 2). The patient responded well to treatment with 8 weeks of oral antibiotics. CT, computed tomography. Brucellosis is a zoonosis caused by Brucella, a genus of gram-negative coccobacillary microorganisms.
