Abstract

Ulcerative Colitis (UC) is a mucosal disease that usually involves the rectum and extends proximally to involve all or part of the colon. Main causes are gut microbiota, dysregulation of the host’s immune system, genetic susceptibility and environmental factors. Active disease can be associated with a rise in acute phase reactants [C - reactive protein (CRP)], platelet count and Erythrocyte Sedimentation Rate (ESR) and a decrease in hemoglobin. Colonoscopy is used to assess disease activity and is often performed before treatment. In this case, recurrence UC was observed and it was treated with suitable therapy but some drug interactions like metronidizole additive effect with ofloxacin results in ST-T elevation and adverse effects like abdominal pain, burning pain in midsternal area radiating to epigastric region [Calcium+Vitamin-D] were seen. Those are monitored by the alternative therapy like dose management and drug alterations.

Introduction

Ulcerative Colitis (UC) is a mucosal disease that usually involves the rectum and extends proximally to involve all or part of the colon. About 40-50% of patients limited to the rectum and rectosigmoid, 30-40% extending beyond the sigmoid but not the whole colon and 20% have a total colitis. When the whole colon is involved, the inflammation extends 1-2 cm into the terminal ileum and is of little clinical significance [1].

Epidemiology

The global prevalence of UC has seen a discernible shift in the past decade. UC once considered to be common in the Western population has witnessed a relative stable or decreasing trend in Western European region [2]. However, its prevalence has seen an upsurge in previously low incidence areas, such as Asia, Eastern Europe and North Indians. Except for a couple of studies from North India in 1965 and 2003 [3-8] there is a dearth of reports on the present prevalence pattern of UC in India. Prevalence of ulcerative colitis to be predominant at the young age (<35 years). Further, gluten-rich diet and out- side food were found to be important factors responsible for increased prevalence. Non- smokers/ex-smokers were found to be high in terms of UC prevalence [9].

Etiology

A consensus hypothesis is that in genetically predisposed individuals, both exogenous factors (e.g., normal luminal flora) and host factors (e.g., intestinal epithelial cell barrier function, innate and adaptive immune function) cause a chronic state of dysregulated mucosal immune function that is further modified by specific environmental factors (e.g., smoking). Although chronic activation of the mucosal immune system may represent an appropriate response to an unidentified infectious agent, a search for such an agent has thus far been unrewarding [1].

Pathophysiology

Antibodies and B-cells: An increase of lymphocytes, especially activated T-cells and IgG containing B-cells, is seen in the colonic mucosa. This may induce the increased production of antibodies directed against intestinal antigens and auto antigens that may contribute to the pathogenesis of this disease.

Cytokines and T-cells: Defective mucosal immunoregulation, including abnormal changes of T-cells, B-cells, granulocytes, macrophages and the cytokines and chemokines produced by these cells resulting in uncontrolled and sustained inflammation [10].

Clinical Presentation

The major symptoms of UC are diarrhea, rectal bleeding, tenesmus, passage of mucus and crampy abdominal pain. The severity of symptoms correlates with the extent of disease. Although UC can present acutely, symptoms usually have been present for weeks to months. Occasionally,diarrhea and bleeding are so intermittent and mild that the patient does not seek medical attention (Table 1).

Laboratory, Endoscopic and Radiographic Features

Active disease can be associated with a rise in acute phase reactants [C - reactive protein (CRP)], platelet count and Erythrocyte Sedimentation Rate (ESR) and a decrease in hemoglobin. Fecal calprotectin levels correlate well with histologic inflammation, predict relapses and detect pouchitis. Sigmoidoscopy is used to assess disease activity and is often performed before treatment. If the patient is not having an acute flare, colonoscopy is used to assess disease extent and activity [1].

Treatment

Therapeutic options can be divided into those that attempt to modify the presumed etiopathogenesis of UC and those that attempt to control the symptoms. Most patients with UC experience relapse and disease progression during their clinical course. Therapy for UC has been categorized an induction therapy, maintenance therapy, treatment for refractory disease and surgery. Efficacious acute therapy and safe maintenance therapy are essential for the medical treatment of UC. Physicians should treat patients according to the revised guidelines prepared by the Ministry of Health and Welfare disease study group in 1998, taking into account the severity, extent and type of disease in individual cases. Aminosalicylate preparations (5-ASA), corticosteroids and immunomodulators are the three main classes of agents used in the medical treatment of UC. Antispasmodics (primarily anticholinergic agents) and antidiarrheal preparations are recommended to improve the symptoms that accompany UC. Low doses of antidepressants are occasionally employed to ameliorate Inflammatory Bowel Syndrome (IBS) symptoms in patients with UC [10].

Complications

• Only 15% of patients with UC present initially with catastrophic illness. Massive hemorrhage occurs with severe attacks of disease in 1% of patients and treatment for the disease usually stops the bleeding. However, if a patient requires 6-8 units of blood within 24-28 h, colectomy is indicated.

• Perforated bowel-chronic inflammation of the intestine may weaken the intestinal wall to such an extent that a hole develops

• Toxic megacolon- severe inflammation leads to rapid enlargement of the colon [11].

Case Report

A 45 year adult female patient, weighing about 54kg admitted in a Tertiary Care Hospital of Gastroenterology ward with the complaints of loose stools for every 15 minutes since 1 month with mucous and blood, abdominal pain and nausea. Previously she was suffered with Ulcerative Colitis (UC) with similar complaints one year back and recovered by taking medications for about 6months, family history was unknown.

Day-1: On examination was normal and Vital signs of elevated temperature (99°F), symptoms was treated with the Ofloxacin 200mg BID, Metronidazole 5mg/ml TID, Hydrocortisone-100mg BID, Mesalamine 800mg TID, Calcium+vitamin-D 50mg. IV fluids- DNS and RL 1 pint and advices of complete blood picture (Hemoglobin count-11.5gm%), ESR (34mm/hour), Serum electrolyte estimation (Normal), sigmoidoscopy (Small hemorrhoids-UC) (Figure 1).

Figure 1: Granular friable mucosa with loss of vascular pattern.

Day-2: C/o- Neck pain, general weakness, abdominal pain, loose motions for every 10 minutes with blood. Advices are thyroid profile test (normal), 2D echo (Sclerotic aortic valve and Mild Tricuspid valve regurgitation) ECG (ST-T elevation), Trop-T (negative), CPK MB (negative) and Hydrocortisone changed to Prednisolone 40mg OD, continued the same medications.

Day-3: C/o- Neck pain, chest pain at right side, burning pain in midsternal area radiating to epigastric, loose motions 6 episodes at night with blood, mild abdominal pain. Stop Calcium+Vitamin-D (because acute gastritis observed) Sucralfate-O-Gel 10ml TID, Ofloxacin/ornidazole 200 /500mg OD, Prednisolone 40mg OD and continued the same medication.

Day-4: C/o- Loose motions with blood 6 episodes, pain in abdomen and continued the same medication.

Day-5: C/o- Loose motions with blood 3 episodes at night and continued the same medication.

Day-6: C/o- Loose motions with blood were decreased and patient was kept on observation for one day and discharged with stable condition.

Role of pharmacist in improving patient health and decrease prescription errors

Interventions

Drug interaction: On Day-2 Drug-Drug interaction was found and it was a major interaction.

Metronidazole+Ofloxacin: It shows additive ST-T elevation and it is clinically managed by ECG Monitoring and alteration of dose of any drug, in this patient Metronidazole 5mg/ml TID reduced to BID.

ADR: On Day-3 Calcium+Vitamin-D 500mg OD causes acute gastritis (Mild abdominal pain, burning pain in midsternal area radiating to epigastric region) so it was stopped but in the discharge medication chart it was prescribed to maintain vitamin-D levels in UC disease condition.

Points to patient by clinical pharmacist: Maintain normal body weight, high intake of fiber containing foods, consume diet rich in antioxidants, fruits, vegetables, decrease intake of spicy food & potassium intake, high intake fluid to overcome fluid imbalance.

Discussion

Limited data suggest that metronidazole may rarely prolong the QT interval of the electrocardiogram. In general, the risk of an individual agent or a combination of agents causing ventricular arrhythmia in association with QT prolongation is largely unpredictable but may be increased by certain underlying risk factors such as congenital long QT syndrome, cardiac disease and electrolyte disturbances (e.g., hypokalemia, hypomagnesemia) [12]. But in this case from day 1 to day last serum electrolytes are normal and absence of past cardiac diseases. So it was mainly due to the drug interaction of metronidizole additive effect with ofloxacin results in ST-T elevation but no elevation/prolongation of QT interval. Thus, vitamin D deficient IBD patients are at an increased risk of fractures and low bone density, especially if they have longstanding disease, or have long courses of steroids [13]. But in this case Calcium+Vitamin-D 500mg OD causes Mild abdominal pain, burning pain in midsternal area radiating to epigastric region. So it was discontinued for few days and then added in the discharge medication chart to maintain vitamin-D levels.

Conclusion

In this case, recurrence UC was observed and it was treated with suitable therapy but some drug interactions like metronidizole additive effect with ofloxacin results in ST-T elevation but no elevation/ prolongation of QT interval and adverse effect like abdominal pain, burning pain in midsternal area radiating to epigastric region [Calcium+Vitamin-D] were seen and those are monitored by the alternative therapy like dose management and drug alterations.

Outcomes and Safety of Open vs. Laparoscopic Surgery in Patients with Cirrhosis

Background & Aims: The risk of laparoscopic surgery in cirrhotics remains unclear. We report on outcome and safety of open versus laparoscopic surgery in cirrhotics.

Methods: Retrospective review of cirrhotics undergoing abdominal or pelvic surgery at a university hospital from 2000 to 2010. Pre-, intra-, and post-operative data was collected. Open and laparoscopic patients were compared for post-operative outcomes including minor and major complications, hepatic decompensation, and mortality. Patients were stratified by Child-Pugh and MELD scores, and emergent vs. elective surgery. 164 total patients were identified (131 open and 31 laparoscopic).

Results: There was significantly more intra-operative blood loss (p<0.001) and minor complications (p=0.043) in the open group, but no other significant differences between the laparoscopic and open patients. All 5 deaths occurred in open patients (p=0.58). Increasing Child and MELD scores were predictive of adverse events. Overall complications, hepatic decompensation (p=0.015) and death (p<0.022) were more common in open emergent compared to open elective cases. In open emergent Child C patients, 100% had major complications and hepatic decompensation and 67% died. Of emergent open MELD>20 patients, 100% had major complications, 67% had hepatic decompensation, and 33% died.

Conclusion: Open and laparoscopic surgical approaches for cirrhotics yielded similar safety and outcomes. Child and MELD scores were predictive of adverse outcomes. Emergent cases were more likely to have complications than elective cases. Further studies including larger numbers of emergent laparoscopic patients are needed to better ascertain the risk of laparoscopy in cirrhotics.

Case Series and a Review of Cannabinoid Hyperemesis Syndrome

Cannabinoid hyperemesis syndrome (CHS) is a condition observed in patients with chronic use of cannabis. It is characterized with GI symptoms including nausea, vomiting, abdominal pain and diarrhea. The patients tend to be chronic abusers for several years and experience these symptoms in a cyclical manner similar to the cyclical vomiting syndrome. They find relief after taking hot baths, a pathognomonic feature of CHS. We hereby describe 3 cases who presented with clinical features consistent with CHS. Cannabis acts through CB1 and CB2 receptors located in brain and gastrointestinal tract, respectively. There are no standard therapeutic measures available for management of CHS. We propose the idea of using short-acting cannabinoids including dronabinol. Also review of literature suggests treatments with drugs including clonidine, lorazepam and risperidone. Recent endeavors on legalization of recreational cannabis use have initiated several debates and we should be mindful of CHS as one of its long-term complications.

Pharmacological Characterization of Muscarinic Receptor Subtypes Involved in Carbachol-Induced Contraction of the Chicken Proventriculus

Present study was designed to characterize the postjunctional muscarinic acetylcholine receptor mediating contraction of the chicken proventriculus by using muscarinic receptor agonists and antagonists. Muscarinic agonists caused concentration-dependent contraction. The ranking order of pEC50 values were muscarine > arecaidine propargyl ester > oxotremorine M > carbachol > methacholine > arecoline > acetylcholine > bethanechol = McN-A343 = pilocarpine. The responses to carbachol were competitively antagonized by AF-DX116 (pKb =5.9), AF-DX384 (6.84), 4-DAMP (8.79), methoctramine (5.81), pirenzepine (6.78), p-F-HHSID (7.41), atropine (8.43),tropicamide (6.91), himbacine (7.01), AQ-RA741 (6.6) and dimethindene (6.73). The correlation of pKb of the chicken proventriculus with that of the mammalian M3 receptor was the highest among five muscarinic receptors. The proventriculus membrane contained a single class of [3 H]-quinuclidinyl benzilate binding sites. pKi values of the antagonists in a binding displacement study correlated with that of the M3 subtype. Pertussis toxin(100µg/kg, i.p. for 72h) significantly decreased the contraction induced by a low concentration of carbachol. In 4-DAMP mustard and AF-DX116-pretreated muscle strips, AF-DX116 shifted the concentration-response curve for oxotremorine M to the right in the presence of 5-hydroxytryptamine and forskolin. The pKb value (6.22) was significantly higher than that obtained in the normal condition (5.78). Isoproterenol increased cyclic AMP, and carbachol significantly decreased the isoproterenol-induced increase in cyclic AMP. The results indicated that a muscarinic agonist mainly acts on the M3 receptor to cause contraction of the chicken proventriculus but the possible involvement of M2 /M4 receptors cannot be excluded as demonstrated in mammalian gastrointestinal tract.

Prediction and Diagnosis of Fatty Liver in Dairy Cows

Fatty liver is defined as an accumulation of fat, mainly Triacylglycerol (TAG) in liver. Fatty liver in dairy cows is categorized into mild, moderate and severe fatty liver. Obesity in pregnant cow is crucial etiological factor for postpartal development of fatty liver. Namely, obese cows have a greater decrease in feed intake during the period around parturition and, therefore, have a more severe negative energy balance during early lactation which leads to increased lipolysis of adipose tissue. Non Esterified Fatty Acids (NEFA), released from the stored TAG in the adipose tissue, are readily taken up by liver. The excess of NEFA may be converted to TAG and deposit in liver. Liver biopsy is the only reliable method for the detection of fatty liver, especially for the determination of its severity through the estimation of total lipids and TAG. Ecography may be considered as noninvasive, on-farm method for diagnosis of fatty liver which is not commonly used do to the not widely achievable equipment. Since some metabolic and endocrine parameters are significantly correlated with fatty liver degree, they may be used as diagnostic indicators of fatty liver. The significance of those indicators for diagnosis of fatty liver is present in this review. Additionally, indicators that may be used for prediction of fatty liver are explained. Specially attention was given to glucose, NEFA, BHBA, liver enzymes, total bilirubin, total protein, albumin and urea as well as some hormones involved in lipid metabolism. Achievements of novel methods, like genomic and proteomic profiling of biological fluids of diseased cows, in providing tools for diagnosis and prognosis of this metabolic disease are presented.

Primary Gastric Lymphoma

The treatment of primary gastric lymphoma is evolving in post-rituximab era. The role of Helicobacter pyroli eradication alone can cure not only Mucosa-Associated Lymphoepithelial Tumor (MALT) but also some of diffuse large B cell lymphoma with or without MALT component. The efficacy of rituximab containing chemotherapy is so effective that the role of surgery is overshadowed. There are many studies, although most of them were retrospective trials, however it highlights the current mainstay of immune-chemotherapy provided an outstanding long term survival more than 80-90%.H pylori In real world there are substantial patients may receive surgery first, yet still needs post-operative adjuvant chemotherapy for some of them has a risk of relapse of lymphoma. And recent studies showed there’s no statistical difference between the two modalities. The main reason for patients proceeded to surgery as primary treatment is the gastroenterologist preference and showed no difference in terms of progression free survival and overall survival. The rituximab was introduced to lymphoma treatment since 1999, and demonstrated a superior long term survival in diffuse large B cell lymphoma for R-CHOP relatively to CHOP regimen. The highly effective treatment made PGL being easily curable disease; furthermore there are new insights of why and how the antibiotic therapy as exclusive treatment for limited disease will be a mainstay in treating this malignancy. We make a proposal how to treat the primary gastric lymphoma and MALT, and highlight the changing treatment modalities with regards to the integration of Helicobacter pyroli eradication to conventional chemotherapy as well as the complimentary role of surgery and radiotherapy.

Bleeding Peptic Ulcer: Epidemiology, Treatment and Prognosis

Aims: The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute Upper Gi Bleeding (UGIB) with a focus on Peptic Ulcer Bleeding (PUB).

Methods: This study included 2198 consecutive patients that were referred to our emergency department due to acute Upper Gi Bleeding (UGIB) from January 2008 to December 2012. All patients under went urgent upper GI endoscopies within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed.

Results: The cumulative incidence of UIGB was 126/100000 for a 5-year period. Two out of five patients had a bleeding peptic ulcer, of which 440 (52.3%) patients had a bleeding gastric ulcer, 356 (42.3%) had a bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomosis. PUB was more common in men. Average patient age was 65.9 years. The majority of patients with PUB were taking agents that attenuate the cytoprotective function of the gastric and duodenal mucosa (57%).Half of the patients received a red blood cell transfusion, with a median of 2.2 units. Re-bleeding occurred in 77(9.7%) patients and 47 (5.9%) required surgical intervention. The thirty-day morality was 5.2%, and 10% of patients died from uncontrolled bleeding and concomitant diseases.

Conclusion: PUB is the main cause of UGIB, characterized by a significant re-bleeding rate and mortality.

An Update on Hepatorenal Syndrome

The Hepatorenal Syndrome (HRS) is one of many potential causes of Acute Kidney Injury (AKI) in patients with decompensated liver disease.

HRS is associated with poor prognosis and represents the end-stage of a sequence of reductions in renal perfusion induced by progressively severe hepatic injury.

The pathophysiology of HRS is complex with multiple mechanisms interacting simultaneously, although HRS is primarily characterised by renal vasoconstriction.

A recently revised diagnostic criteria and management algorithm for AKI has been developed for patients with cirrhosis, allowing physicians to commence treatment promptly.

Vasopressor therapy and other general management, such as antibiotic prophylaxis, need to be initiated while patients are assessed for eligibility for transplantation. Liver transplantation remains the treatment of choice for HRS but is limited by organ shortage.

Other management options, such as transjugular intrahepatic portosystemic shunt, renal replacement therapy and molecular absorbent recirculating system, may provide short term benefit for patients not responding medical therapy while awaiting transplantation.

Clinicians need to be aware of the pathophysiology and management principles of HRS to provide quality care for patients with multi-organ failure.

Abdominal CT Findings of Cholecystogastric Fistula

Enteric fistulas are abnormal connections between the gastrointestinal tract and other organs, chest or skin. Fistulas between the gall bladder and the gastrointestinal system are common [1]. Cholecystoduodenal and cholecystocolic fistulas are seen frequently while cholecystogstric ones are rare [2]. In our case, we accidentally discovered a cholecystogastric fistula in a 71 years old male patient with gastric adenocarcinoma in orally and intravenous contrast enhanced abdomen CT.

Post-Colonoscopy Colorectal Carcinomas (PostCRCs): Have we Improved Over Time?

Background and Aim: There is an increasing concern on Post-Colonoscopy Colorectal Carcinomas (PostCRCs). Little is known about how these figures have evolved over time. We aim to compare the rates of PostCRCs in two periods of time and identify the risk factors.

Methods: Retrospective control-case study in our Endoscopic Unit. We studied two separate intervals (March 2004-September 2011 and October 2011 - December 2016). In both periods of time all patients diagnosed with CRC were identified. Patients with a previous colonoscopy performed 12 to 60 months before were retrieved (cases) and compared with those who did not have a previous procedure (controls).

Results: 712 and 743 patients diagnosed with CRC in both periods of time. 24 patients in the first period (3.6%) and 28 patients in the second one (3.8%) had a previous colonoscopy performed. PostCRCs were mainly located on the right side of the colon (63% vs. 35% p=0.006 and 68% vs. 33% p< 0.001), were smaller in size (3.17 vs.4.46 p< 0.001 and 3.61 vs. 4.44 p=0.086), with a tendency to host a better TNM stage. No differences in sex and age were found.

More than half of PostCRCs (58.3% and 60.7%) were attributed to procedure causes, meanwhile10 PostCRCs in both periods were considered new developed CRCs.

Conclusions: Despite what could be expected, we did not find a decrease in the rate of PostCRCs over time. A combination of preventable as much as biological factors would account for their etiology.
