Background and Aims: Vitamin D deficiency is more common in inflammatory bowel disease (IBD) patients than in the general population. However, there are conflicting data about predictive factors of vitamin D deficiency and its potential association with disease activity. The aims of this study were to determine the prevalence and predictive factors of vitamin D deficiency and to evaluate a possible association with disease activity. Methods: A prospective observational study was conducted, including patients with IBD from January to July 2016. The Endocrine Society guidelines were considered for defining levels of serum 25-hydroxyvitamin D (25-OH-D) as follows: deficient (< 20 ng/mL, < 10 ng/mL being severe deficiency), insufficient (21–29 ng/mL), and adequate (> 30 ng/mL). Results: A total of 152 patients (52% men; 47.2 ± 17.3 years) were included, of whom 70% had Crohn’s disease (CD). Thirty-seven percent of patients were on immunosuppressors and 17% were on biologics. The majority were outpatients (88.2%). Mean 25-OH-D levels were 17.1 ± 8 ng/mL (CD: 16.7 ± 8 ng/mL vs. ulcerative colitis: 17.6 ± 7 ng/mL, p = 0.1). Inadequate levels were present in 90.8% of patients (deficiency: 68.4%; insufficiency: 22.4%). A significant negative correlation between 25-OH-D levels and age (r = –0.2, p = 0.04), C-reactive protein (CRP) levels (r = –0.22, p = 0.004), and Harvey-Bradshaw index (HBi) (r = –0.32, p = 0.001) was found. Patients with severe deficiency showed a higher CRP (0.6 vs. 1.4 mg/dL, p = 0.03), erythrocyte sedimentation rate (ESR) (22 vs. 31 mm/h, p = 0.03), and HBi (2 vs. 5, p < 0.001) and lower hemoglobin (13.6 vs. 12.7 g/dL, p = 0.02). There was no association between vitamin D deficiency and gender, type, extent, and duration of disease, surgery, and other measures of disease activity, such as ESR, hemoglobin (these 2 items except for severe deficiency), fecal calprotectin, or Truelove and Witts classification. Conclusions: There is a high prevalence of inadequate levels of vitamin D in IBD patients, particularly deficiency (68.4%). There seems to exist an association between lower levels of vitamin D and higher disease activity, especially in CD.
Von Willebrand disease (vWD) is the most prevalent hereditary bleeding disorder, affecting 0.6–1.3% of the population. While gastrointestinal bleeding from angiodysplasia is a well-known complication of vWD, the same is not true for Dieulafoy’s lesions (DLs). We report the case of a 21-year-old black male with type 1 vWD and 2 previous hospital admissions for severe anemia with no visible blood loss. In both episodes, DLs were identified and treated endoscopically, one in the stomach and another in the duodenum. The patient presented to the emergency department in September 2016 with dizziness, fatigue, and again no visible blood loss. He was hemodynamically stable, and laboratory workup showed a hemoglobin level of 3.4 g/dL. After transfusion of packed red blood cells, intravenous iron, and von Willebrand factor/factor VIII concentrate infusions, the patient underwent upper endoscopy and colonoscopy, which were normal. Small-bowel capsule endoscopy showed dark blood and a fresh clot in the proximal jejunum. At this site, push enteroscopy identified a pulsatile vessel with an overlying minimal mucosal defect, consistent with a DL, type 2b of the Yano-Yamamoto classification, which was successfully treated with adrenaline and 2 hemoclips. The patient remains stable after 18 months of follow-up, with a hemoglobin level of 13.2 g/dL. This is a case of recurrent severe occult gastrointestinal bleeding from multiple DL in a young patient with vWD who is otherwise healthy. Three other cases of DL bleeding in the setting of vWD have been reported in the literature, suggesting a possible association between these 2 entities.

The low-phospholipid-associated cholelithiasis (LPAC) syndrome is a form of symptomatic cholelithiasis occurring in young adults, characterized by recurrence of symptoms after cholecystectomy and presence of hepatolithiasis. The case refers to a healthy 39-year-old Caucasian male who presented with abdominal pain and jaundice. His blood tests showed conjugated hyperbilirubinemia and elevated liver enzymes (total bilirubin 6.65 mg/dL, γ-glutamyltransferase 699 IU/L) and abdominal computed tomography revealed dilation of common bile duct and left intrahepatic ducts. Magnetic resonance cholangiopancreatography identified choledocholithiasis, retrieved by endoscopic retrograde cholangiopancreatography, after which there was a worsening of jaundice (total bilirubin 23 mg/dL), which persisted for several weeks, possibly due to ciprofloxacin toxicity. After an extensive workup including liver biopsy, the identification of two foci of hepatolithiasis on reevaluation abdominal ultrasound raised the hypothesis of LPAC syndrome and the patient was started on ursodeoxycholic acid, with remarkable improvement. Genetic testing identified the mutation c.1954A>G (p.Arg652Gly) in ABCB4 gene (homozygous) and c.1331T>C (p.Val444Ala) in ABCB11 gene (heterozygous). In conclusion, we describe the unique case of an adult male with choledocholithiasis, hepatolithiasis, and persistent conjugated hyperbilirubinemia after retrieval of stones, fulfilling the criteria for LPAC syndrome and with possible superimposed drug-induced liver injury, in whom ABCB4 and ABCB11 mutations were found, both of which had not been previously described in association with LPAC.
OBJECTIVE: To compare sonographic and magnetic resonance imaging findings in deep endometriosis with emphasis on intestinal involvement. MATERIALS AND METHODS: Eighteen women aged between 23 and 49 years with clinical suspicion and gynecological signs suggestive of deep endometriosis were submitted to ultrasonography and magnetic resonance imaging for correlation between findings. RESULTS: Ultrasonography detected 40 lesions while magnetic resonance imaging detected 53 lesions in the pelvis. A comparative study has not shown any statistically significant intermethod difference in the detection of lesions (respectively p > 0.19 and p > 0.14). In the rectosigmoid junction, magnetic resonance imaging has detected one (5.6%) lesion, while ultrasonography has detected four lesions (22.2%). In the rectum, ultrasonography has detected eight lesions (44.4%), and magnetic resonance imaging has detected seven lesions (38.9%). CONCLUSION: The intermethod agreement has not been good for lesions in the rectosigmoid junction, considering that ultrasonography has detected a higher number of lesions in this region, but a lower number of lesions in the pelvis as compared with magnetic resonance imaging. The global comparative analysis has demonstrated no statistically significant intermethod difference in the detection of lesions. Low cost, good tolerability and high availability make ultrasonography a valuable diagnostic tool in cases of deep endometriosis. Keywords: Deep endometriosis; Diagnosis; Transvaginal ultrasonography; Magnetic resonance imaging.OBJETIVO: Comparar achados ultrassonográficos e de ressonância magnética na endometriose profunda, com ênfase para o comprometimento intestinal. MATERIAIS E MÉTODOS: Dezoito pacientes entre 23 e 49 anos de idade, com suspeita clínica e exame ginecológico sugestivo de endometriose profunda, foram submetidas a ultrassonografia e ressonância magnética para correlação dos achados. RESULTADOS: A ultrassonografia detectou 40 lesões e a ressonância magnética detectou 53 lesões na pelve. O estudo comparativo entre ultrassonografia e ressonância magnética na detecção das lesões não mostrou diferença estatís-tica significativa (p > 0,19 e p > 0,14, respectivamente). Considerando-se a junção retossigmoide, a ressonância magnética detectou uma lesão (5,6%) e a ultrassonografia apontou quatro lesões (22,2%). Nas lesões retais, a ultrassonografia apontou oito lesões (44,4%) e a ressonância magnética, sete lesões (38,9%). CONCLUSÃO: A concordância entre a ressonância magnética e a ultrassonografia não foi boa na junção retossigmoide e no reto, sendo que a ultrassonografia detectou um número maior de lesões nessas localizações, mas identificou número menor de lesões na pelve. Na análise comparativa global entre os dois méto-dos na detecção das lesões não houve diferença estatística significativa. O baixo custo, a boa tolerabilidade e o fácil acesso tornam a ultrassonografia instrumento diagnóstico valioso na endometriose profunda. Unitermos: Endometriose profunda; Diagnóstico; Ultrassonografia ...

Actinomycosis is a rare but easily curable infection that should be considered in the differential diagnosis of perianal fistulizing disease. We present the case of a 26-year-old woman with complex perianal fistulae, including trans-sphincteric and suprasphincteric fistulous tracts and a rectovaginal fistula, requiring multiple abscess drainages, seton placement, and antibiotic courses, with little improvement. After extensive investigation, Actinomyces spp. was identified in anal cytology. The patient underwent a 6-week course of intravenous penicillin followed by oral amoxicillin, with remarkable improvement. This case illustrates the importance of pursuing less common diagnoses in refractory complex perianal disease, such as actinomycosis.
