Turki M Alkharfy, Rubana Ba-Abbad, Anjum Hadi, Badr H Sobaih, Khalid M AlFaleh
September-October 2014, 20(5):293-296
DOI:10.4103/1319-3767.141688  PMID:25253364
Background/Aim: Development of hepatic dysfunction is a well-recognized complication of total parenteral nutrition in preterm infants. Previous studies reported the incidence of total parenteral nutrition-associated cholestasis and described possible contributing factors to its pathogenesis, but little is done trying to determine its possible predictive risk factors. The aims of this study was to determine the incidence of total parenteral nutrition-associated cholestasis and to develop a possible predictive model for its occurrence. Patients and Methods: A review of medical records of all very low birth weight infants admitted to neonatal intensive care unit at King Khalid University Hospital, Riyadh, Saudi Arabia, between January 2001 and December 2003 was carried out. The infants were divided into two groups: Cholestasis and noncholestasis, based on direct serum bilirubin level >34 μmol/L. A multivariate logistic regression analysis was performed to calculate the statistical significance of risk factors. Receiver-operating characteristic curve was used to determine the optimal cutoff points for the significant risk factors and to calculate their sensitivity and specificity. The level of significance was set at P ≤ 0.05. Results: A total of 307 patients were included in the analysis. The incidence of cholestasis in the whole population was 24.1% (74 patients). Infants with cholestasis had a lower birth weight, 735.4 ± 166.4 g vs. 1185.0 ± 205.6 g for noncholestasis group (P < 0.001), whereas the mean gestational age for the two groups was 25.4 ± 2.1 week and 28.9 ± 2.1 week, respectively (P < 0.001). The significant risk factors for the development of cholestasis were birth weight (P = 0.006) with an odds ratio of 0.99 [95% confidence interval (CI), 0.98, 0.99]; sensitivity of 92%, specificity of 87%; and total parenteral nutrition duration (P < 0.001) with an odds ratio of 1.18 (95% CI, 1.10, 1.27); sensitivity of 96%, specificity of 89%. Conclusions: A lower birth weight and longer duration of total parenteral nutrition were strong predictive risk factors for the development of cholestasis in preterm infants.

Irina Girleanu, Carol Stanciu, Camelia Cojocariu, Lucian Boiculese, Ana-Maria Singeap, Anca Trifan
September-October 2014, 20(5):288-292
DOI:10.4103/1319-3767.141687  PMID:25253363
Background/Aim: Portal vein thrombosis (PVT) has a high incidence in patients with liver cirrhosis and determines a poor prognosis of hepatic disease. The aim of our study was to define the natural course of partial PVT in cirrhotic patients, including survival and decompensation rates. Patients and Methods: We performed a prospective, cohort study, in a tertiary referral center. There were 22 cirrhotic patients with partial nonmalignant PVT, without anticoagulant treatment, who were followed-up between January 2011 and October 2013. All patients were evaluated by Doppler abdominal ultrasound and computed tomography. Kaplan-Meier method was used to determine the difference in clinical events between the study subgroups. Results: After a mean follow-up period of 20.22 months, partial PVT improved in 5 (22.73%), was stable in 11 (50%), and worsened in 6 (27.27%) patients. Hepatic decompensation rate at 6 and 18 months was higher in patients with worsened PVT than in those with stable/improved PVT (50% vs. 25%, P < 0.0001 and 100% vs. 56.25%, P < 0.0001, respectively). The survival rate at 6 months was 66.66% in worsened PVT group vs. 81.25% (P = 0.005) in stable/improved group, and 16.66% vs. 81.25% (P < 0.0001) at 18 months, respectively. Multivariate analysis showed that Model of End-Life Disease was the independent predictor of hepatic decompensation [hazard ratio (HR) 1.42; 95% confidence interval (CI): 1.08-1.87, P = 0.012] and survival (HR 1.76; 95% CI: 1.06-2.92, P = 0.028). Conclusions: Nonmalignant partial PVT remained stable/improved in over half of cirrhotic patients and aggravated in more than one fourth in whom it negatively influenced the survival and decompensation rates.

Mazen Hassanian, Amnah Al-Mulhim, Atheer Al-Sabhan, Shaden Al-Amro, Fahad Bamehriz, Ayman Abdo, Hisham Al Khalidi
September-October 2014, 20(5):270-278
DOI:10.4103/1319-3767.141684  PMID:25253361
Objective: A review of published data addressing hepatic histopathological, metabolical, and functional changes following gastric banding, sleeve gastrectomy, gastric bypass surgery, and biliopancreatic with duodenal switch surgeries on nonalcoholic fatty liver disease (NAFLD). NAFLD is currently the most common chronic liver disease. Owing to the strong relationship between obesity and NAFLD, the idea of weight reduction as a method to treat NAFLD has rapidly emerged. Bariatric surgery has proved to be the most efficient method for weight reduction; hence, their beneficial effects on NAFLD have been evaluated by several studies. A literature review of published data was performed during the years 2012-2014 using PubMed with the following key words: Bariatric, NAFLD, steatosis, sleeve gastrectomy, gastric bypass, gastric banding, biliopancreatic diversion with duodenal switch, obesity, and insulin resistance (IR). Exclusion criteria were non-English articles and inherited NAFLD, pregnancy-induced NAFLD, and children. The majority of published data are in favor of indicating that bariatric surgeries improve the histologic and metabolic changes associated with NAFLD. The suggested mechanisms are: The reversal of IR, reduction of inflammatory markers, and improved histological features of NAFLD. Accordingly, bariatric surgeries are potentially one of the future methods in treating patients with morbid obesity and NAFLD. However, some questions remain unanswered, such as whether timing of surgery, type of surgery most effective, and whether bariatric surgeries are capable of curing the disease. Long-term and well-designed prospective studies are needed to address these issues.

Ascites and spontaneous bacterial peritonitis: Recommendations from two United States centers
Vinay Sundaram, Vignan Manne, Abdullah MS Al-Osaimi
September-October 2014, 20(5):279-287
DOI:10.4103/1319-3767.141686  PMID:25253362
Cirrhosis affects millions of people throughout the world. Two of the most serious complications of liver cirrhosis are ascites and spontaneous bacterial peritonitis (SBP). The development of ascites is related to the severity of portal hypertension and is an indicator of increased mortality. Although sodium restriction and diuretic therapy have proven effective, some patients may not respond appropriately or develop adverse reactions to diuretic therapy. In such cases, interventions such as transjugular intrahepatic portosystemic shunt (TIPS) placement are warranted. SBP is a complication of ascites that confers a very high mortality rate. Recognition and prompt treatment of this condition is essential to prevent serious morbidity and mortality. Initiation of prophylaxis in SBP remains controversial. Given the burden of liver cirrhosis on the health care system, ascites and SBP will continue to provide challenges for the primary care provider, hospitalist, internist, and gastroenterologist alike.

Background and Aim : Ischemia/reperfusion (I/R) injury in the liver occurs after a prolonged period of ischemia followed by restoration of hepatic blood perfusion. During the surgery of abdominal aorta, I/R injury causes damage to lower extremities and many organs, especially liver. The antioxidant and tumor necrosis factor-alpha (TNF-α) suppression effects of topiramate (TPM) have been reported in several studies. We evaluated the potential protective effect of TPM on cellular damage in liver tissue during I/R injury. Materials and Methods : Thirty male Wistar albino rats were divided into three groups: Control, I/R, and I/R plus TPM (I/R + TPM) groups. Laparotomy without I/R injury was performed in the control group. After laparotomy, cross-ligation of infrarenal abdominal aorta was applied for 2 h in I/R groups that was followed by 2 h of reperfusion. TPM (100 mg/kg/day) was orally administrated to the animals in the I/R + TPM group for seven consecutive days before I/R procedure. Results : The I/R group's TNF-α and interleukin-6 (IL-6) levels were significantly higher than those of the control (P = 0.010; P = 0.002) and I/R + TPM groups (P = 0.010; P = 0.002, respectively). Asymmetric dimethyl arginine (ADMA) levels of I/R group were higher than the control (P = 0.015) and I/R + TPM groups. I/R caused serious histopathological damage to liver tissue; however, TPM led to very low histopathological changes. Conclusion : Our data demonstrated that TPM treatment prominently decreases the severity of liver I/R injury. TPM pretreatment may have preventive effects on liver injury via I/R during intra-abdominal surgery.

Krishnaveni Devulapalli, Amar Chand Bhayal, Shravan Kumar Porike, Ramanna Macherla, Jyothy Akka, Pratibha Nallari, Venkateshwari Ananthapur
September-October 2014, 20(5):309-314
DOI:10.4103/1319-3767.141693  PMID:25253367
Background/Aims: Gastric cancer (GC) is a multifactorial disorder mediated by genetic, epigenetic, and environmental risk factors. GC is the most common cancer in India and it is the third prominent cause of cancer death worldwide. A single nucleotide polymorphism (SNP) in the promoter region of interstitial collagenase (MMP-1) gene appears to have an impact on the transcriptional activity and regulation of its expression. Hence, the present study is aimed to evaluate the role of interstitial collagenase gene-1607 1G/2G (rs1799750) promoter polymorphism in the etiology of GC. Patients and Methods: The study included 166 GC patients and 202 control subjects. Genomic DNA was isolated from whole blood samples of the subjects, and the genotyping of interstitial collagenase promoter polymorphism was carried out by polymerase chain reaction-restriction fragment length polymorphism method followed by agarose gel electrophoresis. Appropriate statistical methods were applied to test the significance of the results. Results: The risk factor profile of the patients revealed that male gender, age above 50 years, addiction to alcohol and smoking were the most common risk factors (P < 0.05). There was a significant difference in the distribution of 2G/2G genotype (2G/2G vs. 1G/1G, P = 0.016) and 1G/2G genotype (2G/2G + 1G/2G vs. 1G/1G, P = 0.010) in patient group compared with that of the control subjects. Conclusion: The present study provides indirect evidence for the role of interstitial collagenase gene 1G/2G promoter polymorphism in the etiology of GC in South Indian population.

Praveen Sharma, Barjesh C Sharma
September-October 2014, 20(5):304-308
DOI:10.4103/1319-3767.141692  PMID:25253366
Background/Aim: Minimal hepatic encephalopathy (MHE) leads to overt hepatic encephalopathy (HE) and impairs quality of life in patients with cirrhosis. Awareness of MHE and its management among physicians is not known. Patients and Methods: We conducted a survey among 673 physicians in India from academic and nonacademic institutes to understand the clinical burden, perceived severity, management patterns, and the barriers to providing care for this condition. Results: Overall awareness of MHE in this survey was 75% (n = 504). Awareness of MHE was significantly higher in physicians working in teaching hospitals compared with those in nonteaching hospitals (79% vs 71%, P = 0.02). Similarly, gastroenterologists were more aware of MHE compared with nongastroenterologists (91% vs 66%, P = 0.001). Only 6.3% physicians screened all of their patients for MHE, whereas frequency of testing for MHE, either being nil or less than 10% of their patients was 64.7%. The most common test was paper and pencil test (86%) and the reason for nonscreening was nonavailability of time to test and also equipment or method (81%). A majority of physicians (88%) think that MHE affects quality of life. Physicians (61%) had an opinion that there should be some registry of MHE regardless of the cost and effort involved. Lactulose was used in 93% of cases, followed by rifaximin (82%) in the management of MHE. Conclusion: The overall awareness of MHE was 75% and it was significantly more in physicians of academic institutes. Despite awareness of its effect on quality of life, a majority of physicians did not test for MHE in their day-to-day practice.

Extranodal marginal zone B-cell lymphoma of Mucosa-Associated Lymphoid Tissue (MALT lymphoma) in ulcerative colitis
Tadashi Terada
September-October 2014, 20(5):319-322
DOI:10.4103/1319-3767.141696  PMID:25253369
Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) occurring in inflammatory bowel diseases, including ulcerative colitis (UC) and Crohn's disease, has been reported, although it is extremely rare. An 18-year-old man with a two-years history of UC underwent colon endoscopy, and was found to have active total UC ranging from anus to cecum. Six biopsies were obtained. The microscopic examinations showed severe infiltrations of atypical small lymphocytes. They showed hyperchromatic nuclei and increased nucleocytoplasmic ratio and scattered immunoblastic cells. Centrocyte-like atypical lymphocytes, monocytoid cells, and plasma cells were seen in some places. Vague germinal centers were present, and apparent lymphoepithelial lesions were seen. No crypt abscesses were seen, and there were few neutrophils. No apparent other findings of UC were seen. Immunohistochemically, the atypical lymphocytes were positive for vimentin, CD45, CD20, CD79α, CD138, κ-chain, λ-chain, and p53 and Ki-67 antigen (labeling index = 63%). They were also positive for CD45RO, CD3, and CD15, but these positive cells were very scant compared with CD20 and CD79α. They were negative for CD10, CD30, CD56, cytokeratin (CK) AE1/3, CK CAM5.2, CK34BE12, CK5, CK6, CK7, CK8, CK14, CK18, CK19, CK20, EMA, chromogranin, synaptophysin, NSE, S100 protein, CEA, CA19-9, p63, and HMB45. Without clinical information, the appearances are those of MALT lymphoma. However, with clinical information, making the diagnosis of MALT lymphoma was hesitated. It is only mentioned herein that atypical lymphocytic infiltrations indistinguishable from MALT lymphoma occurred in an 18-year-old male patient with a two-year history of UC.

Laparoscopic-assisted one-stage resection of rectal cancer with synchronous liver metastasis utilizing a pfannenstiel incision
Murad Aljiffry, Mawaddah Alrajraji, Salman Al-Sabah, Mazen Hassanain
September-October 2014, 20(5):315-318
DOI:10.4103/1319-3767.141694  PMID:25253368
Laparoscopic approaches have been increasingly used in selected patients with either colorectal or liver cancer. However, simultaneous resection of colorectal carcinoma with synchronous liver metastases is still a subject of debate. The present case describes combined laparoscopic rectal and liver resections for a patient with primary rectal cancer and a synchronous liver metastasis utilizing a Pfannenstiel incision for specimen extraction. The operative time was 370 min and estimated blood loss was 400 mL. Postoperatively, the patient required parenteral analgesia for 48 h, resumed normal diet on day 3 and was discharged on day 7 after the operation. A laparoscopic approach utilizing a Pfannenstiel extraction incision may present an advantageous and attractive option for simultaneous laparoscopic rectal and liver resection in selected patients with the aim of improving short-term outcomes.
