ABSTRACT
Ulcerative colitis (UC) is a chronic inflammatory bowel disease usually treated by azathioprine. It is a well-established risk factor for colorectal cancers and extraintestinal malignancies. Nevertheless, the risk of myeloid leukemia in patients with UC is less known. We report a case of a 51-year-old patient, with a history of extensive ulcerative colitis, who was treated with azathioprine at a dose of 2.5 mg/kg/day. Seven years later, he presented an increased count of white blood cells at 25,400/µL and of platelets at 1,382,000/µL. Peripheral blood smear showed 1% blasts and 20% myelemia. The karyotype showed the Philadelphia chromosome and the RT-PCR revealed the BCR-ABL transcript. Thus, chronic myeloid leukemia (CML) was confirmed and imatinib was prescribed. This case reported a rare and serious event in a UC patient and illustrates the importance of closely monitoring this population.

INTRODUCTION: Vitamin D plays a role in regulating the immune response through an immunomodulatory effect, and is probably involved in the pathophysiology of Crohn's disease (CD). AIM: to assess vitamin D status in patients with CD as well as in healthy controls and to determine associated factors of vitamin D deficiency in patients with CD. METHODS: We conducted a prospective study over 18 months, including CD patients with age and sex matched with healthy controls. Suboptimal vitamin D status was defined by vitamin D serum level < 30 ng/ml, vitamin insufficiency by vitamin D serum level between 10 and 30 ng/ml and vitamin deficiency serum level < 10 ng/ml. RESULTS: We included 77 subjects (52 patients with CD and 25 controls) with mean age of 38 years± 11. Most patients and controls had suboptimal levels of vitamin D (98% and 96% respectively) including vitamin D deficiency in 75% and 67%, respectively and vitamin D insufficiency in 25% and 33%, respectively. In univariate analysis, vitamin D deficiency was associated with disease flare-up (p=0.001), anemia (p=0.002), hypo-albuminemia (p=0.002), elevated C-reactive protein (CRP) (p=0.003), Crohn's Disease Activity Index (CDAI) (p<0.001), ileal location (p=0.04) and immunosuppressive therapy (p=0.01). In multivariate analysis, only CDAI was significantly associated with vitamin D deficiency (p=0.003, OR=9.33). CONCLUSION: Vitamin D deficiency is common in Tunisian CD patients as well as in controls and is associated with disease activity.

Isolated hepatic tuberculosis is a rare form of extrapulmonary tuberculosis. We report an exceptional case of a 51-year-old female patient complaining from right upper abdominal quadrant pain, who underwent laparoscopic surgery for millimetric gallbladder polyps. Preoperative ultrasound hepatic morphology and biochemical hepatic tests revealed no abnormalities. There were no clinical patterns for an active tuberculosis. During surgery time, scattered sub-centimeter whitish nodular lesions were discovered on the upper surface of the liver. Although gallbladder pathological examination did not reveal any significant abnormalities, per surgery hepatic biopsy indicated the presence of a giant cell granuloma with caseous necrosis highly suggestive of hepatic tuberculosis. Treatment by anti-bacillary drugs according to local standard protocol was conducted with favorable outcomes. Therefore, diagnosis of hepatic tuberculosis may be considered in endemic countries in totally asymptomatic patients or complaining from unexplained and isolated abdominal pain, in absence of any morphologic or biochemical hepatic abnormalities.

INTRODUCTION: Sarcopenia is an underdiagnosed and understudied complication of cirrhosis, especially in patients not undergoing liver transplantation. AIM: To evaluate the prevalence and prognostic impact of radiological sarcopenia in non-transplanted cirrhotic patients. METHODS: Longitudinal retrospective study including cirrhotic patients explored by an abdominal CT scan, over a period of 6 years, in a single gastroenterology department in Tunisia. Sarcopenia was defined according to transversal psoas muscle thickness normalized to height (TPMT/h) in the sagittal CT slice. Two groups were defined: Group 1 with sarcopenia (TPMT/h <16.8mm/m); and Group 2 without sarcopenia (TPMT/h ≥16.8mm/m). RESULTS: Seventy patients were included (mean age=62 years). The mean MELD score was 12.81 and the mean TPMT/h of 13.56 mm/m. Forty-four patients were sarcopenic (63%). When included, the 2 groups' baseline characteristics were comparable except for women predominance and refractory ascites in group 1. After an average of 21-month follow-up, sarcopenia was associated with a higher number of complications per patient (p=0.013) and a longer average hospital stay duration per patient (p=0.001). Overall survival was significantly decreased in sarcopenic patients (p=0.035). Survival rates at 6 months, 1 year, and 2 years were respectively 42%, 30%, and 24% in Group 1 versus 67%, 40%, and 27% in Group 2. Sarcopenia was an independent factor of mortality in multivariate analysis (OR=2.5; 95% IC [1.02-6.16]; p=0.045). CONCLUSION: Sarcopenia is frequent and an independent poor prognostic factor in cirrhosis. TPMT/h is an easy and often available method for sarcopenia diagnosis.
