A spontaneous portosystemic shunt is a rare malformation of the liver vessels. The etiology of these shunts is controversial. They can be divided into acquired (most commonly associated with liver cirrhosis) and congenital. Vascular shunts are asymptomatic in the majority of the patients, and when symptomatic were presented by severe complications. The specific way of management can be selected depended on whether the patient was symptomatic or not, and also on the size of the shunt, shunt ratio and whether it was associated with cancer. We will present a clinical case and discuss the importance of the radiological imaging in the screening, diagnosis and follow up of these anomalies.

Objectives: This study proposes to evaluate risk factors for kidney disease in HIV patients treated chronically and correlate with microalbuminuria measurements. Methods: Review charts and analyses of microalbuminuria in subgroup of HIV patients treated at Ceara/Brazil. Results: 149 patients, 69.1% male, mean 38.5 years old, infection mean 86.8 months. Mean Creatinine Clearance 110.2%, Creatinine 0.97, Urea 27.76 mg/dl, CD4+ 600.37 cels/mm3 and detectable viral load 530.59 copies with 61.7% undetectable. Mean Dosages of microalbuminuria/24h 147, 46 ± 820, 45 (N = 48) and microalbuminuria (mg/dl) 32.05 ± 85.25 (N = 43). Kidney Diseases Classification analyses evidenced 6.4% patients in stages ≥3 and 6.2% presented altered Microalbuminuria/24h. Patients using Tenofovir (TDF) 27.27% had Stage 2 and protease inhibitors (PI) had 4.1% in Stage 3. Proteinuria was observed in 5% stage ≥3. Association PI/TDF had 4.1% in Stage 3. No statistical difference between CD4 > or 3 and microalbuminuria/24h > 300 mg (p = 0.69);detectable/undetectable viral load and microalbuminuria/24h (p = 0.63) or stage ≥3 (p = 0.17);relation to Diabetes or arterial hypertension and microalbuminuria 24 h (p = 0.5 and p = 0.21);relation stage ≥3 and microalbuminuria/24h (p = 0.33);relation HIV diagnoses >/ or or < 50 years and microalbuminuria/24h (p = 0.55) or microalbuminuria mg/d (p = 0.32). Relating comorbidities risk (Diabetes Mellitus plus Systemic Arterial Hypertension) to Kidney Diseases, it was found that 55.5% patients in Stage 3 or above with comorbidities compared with 15% with comorbidities in lower stages (P = 0.005). Nevertheless, comorbidities presence was not associated with microalbuminuria (p = 0.08). Conclusion: Kidney disease is a real risk for HIV patients and stages ≥

Association between Helicobacterpylori, Epstein-Barr virus, human papillomavirus and gastric adenocarcinomas

AIM TO correlate Helicobacter pylori （H. pylorli）, EpsteinBarr virus （EBV） and human papillomavirus （HPV） with gastric cancer （GC） cases in Para State, *** Tissue samples were obtained from 302 gastric adenocarcinomas. A rapid urease test was used to detect the presence of H. pylori, and the presence of the cagA gene in the HP-positive samples was confirmed by PCR. An RNA in situ hybridization test designed to complement Eberl RNA was used to detect the presence of EBV in the samples, and the L1 region of HPV was detected using nested PCR. Positive HPV samples were genotyped and analyzed for E6 and E7 viral gene expression. Infections were also correlated with the clinical and pathological characteristics of the *** The majority of the 302 samples analyzed were obtained from men （65%） aged 55 years or older （67%） and were classified as the intestinal subtype （55%）. All three pathogens were found in the samples analyzed in the present study （H. pylori： 87%, EBV： 20%, HPV： 3%）. Overall, 78% of the H. pylori-positive （H. pylorl＋） samples were cagA＋（H. pylori-cagA＋）, and there was an association between the cytotoxic product of this gene and EBV. Coinfections of H. pylori-cagA＋ and EBV were correlated with the most advanced tumor stages. Although only 20% of the tumors were positive for EBV, infection with this virus was associated with distant metastasis. Only the HPV 16 and 18 strains were found in the samples, although no expression of the E6 and E7 oncoproteins was detected. The fundus of the stomach was the region least affected by the *** HPV was not involved in gastric tumorigenesis. Prophy- lactic and therapeutic measures against H. pylori and EBV may prevent the development of GC, especially the more aggressive forms.

Vitamin D and Secondary Hyperparathyroidism in HIV Infected Patients Taking Antiretroviral Therapy

Objective: Due to the lack of studies assessing hypovitaminosis D and secondary hyperparathyroidism in Brazilian HIV-infected population, especially in the northeastern population, this study aimed to determine the profile of these conditions in patients infected with HIV and its correlation with immuno-virological, sociodemographic data and associated comorbidities. Methods: Comparison studies were obtained from routine clinical samples of HIV infected patients submitted for 25-OH Vitamin D, PTH and alkaline phosphatase determination. Results: A total of 78 patients were included, 42 (53.8%) males, mean age 45.7 years. Antiretroviral regimens most used in this study were Zidovudine/Lamivudine/Efavirenz 17.9%, Tenofovir/Lamivudine/Efavirenz 17.9%,Tenofovir/Lamivudine/Atazanavir-r 15.4%. The mean value CD4 count was 592.1 ± 247.2 cells/mm3, CD8 cell count was 1026.5 ± 467.3 cells/mm3, mean detectable viral load was 2220 ± 15703 copies and CD4/CD8 ratio was 0.63 ± 0.33. A total of 34 vitamin D dosages were collected with 41.2% representing sufficient amount and 58.8% insufficient. Alkaline Phosphatase (ALP) dosage was elevated in 49.3% (N=35) of the patients. Parathormone (PTH) was elevated in 18% (N = 11). Among patients with elevated PTH levels, 81.9% had elevated levels of ALP (p = 0.01). In the group of patients with high levels of ALP, 45.7% had a CD4 count 3 (p = 0.02). There was no significant difference in vitamin D related to gender (p = 0.21), age (p = 0.23), CD4 count (p = 0.26), suppressed viral load (p = 0.44) or blood glucose (p = 0.45). Conclusions: This study evidenced a high prevalence of Vitamin D insufficiency in Northeast Brazil, which suggests HIV infection correlation. A high prevalence of Hyperparathyroidism was detected and related with inflammatory condition persistence and low CD4 count. We suggest improve vitamin D follow up and measurements in this population with better CD4 count control to avoid future osteoarticular complications of HIV
