Microscopic Colitis: A Diagnostic Challenge in Patients with Irritable Bowel Syndrome

BACKGROUND AND AIMS

Irritable Bowel Syndrome (IBS) is one of the most frequently diagnosed gastrointestinal disease with a prevalence of 4.1% in the general population. It is diagnosed using the Rome IV criteria. Microscopic colitis (MC), collagenous/lymphocytic colitis is a cause of chronic, watery, non-bloody diarrhea. It is a real challenge to diagnose MC in patients with IBS. The aims of the study were to determine the prevalence of MC in patients initially diagnosed with IBS, as well as to correlate fecal calprotectin levels with the endoscopic findings and microscopic inflammation in MC.

METHODS

This is a retrospective study conducted in a single tertiary center with over 89 IBS patients for a period of 4 years. The patients included were patients diagnosed with IBS predominant diarrhea (IBS-D) and mixed IBS (IBS-M) using the Rome IV criteria. Total colonoscopy was performed in these patients, multiple biopsies being taken and calprotectin levels were measured.

RESULTS

Out of a total of 89 IBS-D patients, 58 patients (65.2%) had no microscopic lesions, 12 patients (13.5%) had diverticular disease, 9 patients (10.1%) had non-specific chronic inflammation of the colon mucosa and 10 patients (11.2%) were diagnosed with MC. The calprotectin levels ranged from 49 μg/g to 213 μg/g. Of a total of 10 patients diagnosed with MC, 6 (60%) of them had calprotectin levels <100 μg/g and 4 (40%) had calprotectin levels >100 μg/g. The fecal calprotectin levels were higher in patients diagnosed with MC compared to those who had no microscopic lesions at the histological exam and it was also correlated with the grade of colonic microscopic inflammation.

CONCLUSIONS

Microscopic colitis is less familiar to physicians and can be clinically misdiagnosed as IBS-D. An early and correct diagnosis is important for an accurate therapy.

Romanian Guidelines for Nonpharmacological Therapy of IBS

BACKGROUND AND AIMS

The nonpharmacological therapy in irritable bowel syndrome (IBS) is expanding rapidly. Practitioners and medical educators need to be aware of progress and changes in knowledge of this topic. The Romanian Society of Neurogastroenterology aimed to create guidelines based on best evidence on the use of nonpharmacological therapy in IBS.

METHODS

A group of experts was constituted. This was divided in eleven subgroups dedicated to eleven categories of nonpharmacological therapy. The subgroups searched the literature and formulated statements and recommendations. These were submitted to vote in order to obtain consensus.

RESULTS

The outcome of this activity is represented by the guidelines of the Romanian Society of Neurogastroenterology, presented in this paper. The recommendations are seen as complementary to the pharmacological therapy and are not intended to recommend avoiding pharmacological drugs.

CONCLUSIONS

These guidelines were elaborated by a Delphi process and represent a useful tool for physicians managing patients with IBS.

Cardiac Arrhythmias and Electrocardiogram Modifications in Non-Alcoholic Fatty Liver Disease. A Systematic Review

BACKGROUND AND AIMS

Recent studies have evaluated the relationship associating non-alcoholic fatty liver disease (NAFLD) with several electrocardiogram (ECG) findings, but the results have been inconsistent. The aim of this systematic review is to assess the association between NAFLD with ECG modifications.

METHODS

We conducted a systematic search on PubMed with predefined keywords identifying observational studies published till 22 February 2019 with NAFLD diagnosed either by biopsy, imaging, surrogate markers or ICD code and ECG findings by either a standard ECG, 24-hour Holter ECG or ICD code. Quality assessment was performed using the quality assessment tools from the National Heart, Lung, and Blood Institute.

RESULTS

A total of 20 observational studies (1 case-control, 4 cohort, 15 cross-sectional studies, 401,745 individuals) were included. Twelve studies evaluated cardiac arrhythmias in NAFLD subjects, out of which 10 evaluated atrial fibrillation (AF). Although results were inconsistent, most studies rated as "good" demonstrated that hepatic steatosis was independently associated with an increased risk for prevalent AF in NAFLD patients. Diabetic patients with NAFLD were associated with an increased risk of ventricular arrhythmias in only one study rated as "good". Two studies rated as "good" demonstrated that hepatic steatosis was associated with a prolonged QTc interval. Four studies supported the association between cardiac conduction abnormalities and NAFLD, out of which two were rated as "good". Two studies assessed ECG modifications of ischemic heart disease (IHD), but only one having a "good" rating confirmed this independent association.

CONCLUSIONS

Studies of high quality and with low risk of bias demonstrated that NAFLD is independently associated with AF, a prolonged QTc interval, bundle branch and atrioventricular blocks. Diabetic patients with NAFLD present an increased risk for developing ventricular arrhythmias.

Phenotypic features of patients with post-infectious irritable bowel syndrome

Background

Although there are many published data in the literature about irritable bowel syndrome (IBS), there are only few data on the long term evolution of patients with post infectious irritable bowel syndrome (PI-IBS) and associated conditions.

Aims

The purpose of our research was to study the evolution of PI-IBS patients in a single tertiary center over a period of four years.

Study Design

Our research was a longitudinal retrospective study.

Methods

We carried out this study based on the survey of the patients records. We recruited two groups of patients: patients with classical IBS and patients with PI-IBS. The IBS diagnosis was established using ROME III criteria, which were used at that time. We compared the two groups of patients by analyzing the demographic data, comorbidities, treatment that was prescribed, and evolution after treatment for a period of 48 month on average.

Results

From a total of 592 patients that were diagnosed with IBS between 2013-2016, we identified a subgroup of 64 patients with PI-IBS. These patients were also divided into two subgroups, depending on the main symptoms, 51 with PI-IBS - diarrhea and 13 of them with PI-IBS-constipation. IBS is the most commonly diagnosed among women, 45 patients were women and 15 were men. Regarding the frequency of occurrence of a certain subtype by gender, no significant differences were observed in both IBS and PI-IBS. We noticed a higher incidence of patients residents of an urban community in both groups.The main symptoms were: abdominal pain and bowel disorders (constipation, diarrhea).There was a significant difference between the two groups regarding the onset of the symptoms. From the total of 64 patients with PI-IBS, 88.3% presented a sudden onset of symptoms (mainly abdominal pain) unlike the other group where 81% of them presented a progressive onset, with an insidious progress and sporadic exacerbation. Most patients (65.63%) presented an improvement after the treatment, 25.56% oscillating periods but with a significant decrease of intensity of symptoms, and 7.8% did not show improvement after treatment.The most common associated diseases were depression and anxiety (34.37%).

Conclusion

IBS is generally present in approximately 11% of the population, with PI-IBS patients accounting for approximately 10% of them. Female gender is more common in both IBS and PI-IBS. Patients with PI-IBS are a burden in the health system in terms of the important economic resources used for diagnosis and treatment.

Abdominal ultrasound in paraneoplastic Pyoderma gangrenosum caused by renal carcinoma

We present the case of a 60-year-old male patient, with refractory ulcers in the groin. Ultrasoundand CT showed a large vascularized tumor of the kidney with cystic parts and inhomogeneous dynamic behaviour. Histology demonstrated Pyoderma gangrenosum (ulcer) and well differentiated adenocarcinoma (kidney). Pyoderma gangrenosum appears as paraneoplastic manifestation in about 7% of cases, especially in lymphomas and tumors involving the digestive tract.Particularities of the case consisted in the accidental discovery of the renal tumor, in spite of the lack of urinary syndromes. The present case highlights the importance of tumor screening in patients with atypical antibiotic-refractory skin ulcers.

PREVALENCE OF OVERWEIGHT AND OBESITY IN A ROMA POPULATION FROM SOUTHERN ROMANIA - CALARASI COUNTY

Introduction

The prevalence of obesity has reached alarming levels in the European Union, including in Romania. Data on the prevalence of obesity is only available at the national populational level, but this may hide the increased levels in disadvantaged groups. The purpose of this study was to evaluate the prevalence of overweight and obesity in the Roma population in Southern Romania.

Material and method

This cross-sectional, epidemiological, non-interventional study was conducted from March 2014 to May 2017 in several settlements from Calarasi County. Screening procedures included interviews about medical history, lifestyle, anthropometric and clinical measurements and fasting capillary glucose.

Results

The study population consisted of 1120 adult subjects, of which 735 Roma. In Roma population group, the prevalence of underweight, normal weight, overweight and obesity was 4.5% (n=33), 25% (n=184), 25.3% (n=186) and 45.2% (n=332) respectively. In Romanian Caucasians group, the prevalence of underweight, normal weight, overweight and obesity was 2.3% (n=9), 20% (n=77), 33.8% (n=130) and 43.9% (n=169) respectively. Among the Romanian Caucasians significant predictors of obesity were a sedentary lifestyle and current smoking. The odds of being obese in Roma population were higher in sedentary lifestyle persons and lower in current smokers, with primary education, and in those living in rural settlements. The family history of obesity had a significant association with obesity only in Roma population.

Conclusions

Our results confirm the need to implement prevention programs in high-risk populations due to the double burden of malnutrition, lack of medical education and preventive healthcare, low socio-economic level.

Illuminating gravitational waves: A concordant picture of photons from a neutron star merger

Merging neutron stars offer an excellent laboratory for simultaneously studying strong-field gravity and matter in extreme environments. We establish the physical association of an electromagnetic counterpart (EM170817) with gravitational waves (GW170817) detected from merging neutron stars. By synthesizing a panchromatic data set, we demonstrate that merging neutron stars are a long-sought production site forging heavy elements by r-process nucleosynthesis. The weak gamma rays seen in EM170817 are dissimilar to classical short gamma-ray bursts with ultrarelativistic jets. Instead, we suggest that breakout of a wide-angle, mildly relativistic cocoon engulfing the jet explains the low-luminosity gamma rays, the high-luminosity ultraviolet-optical-infrared, and the delayed radio and x-ray emission. We posit that all neutron star mergers may lead to a wide-angle cocoon breakout, sometimes accompanied by a successful jet and sometimes by a choked jet.

Four years Follow-up of Patients with Irritable Bowel Syndrome

There is little data on the long term evolution of patients with irritable bowel syndrome (IBS) and of associated conditions. We therefore studied the evolution of IBS patients in a single tertiary center during a long interval of time.

METHODS

We carried out a retrospective study based on the survey of patients records. We analyzed the records of symptoms, therapy, associated diseases, as consigned at follow-up visits for an interval of 4 years in average (2008-2011).

RESULTS

A cohort of 114 patients with IBS diagnosed based on Rome III criteria were included (29 men and 85 women), age 19-85 years (mean age: 43.45 years). Urban patients were predominant. The main three symptoms were: abdominal pain, bowel disorders (constipation, diarrhea) and bloating. IBS--constipation (IBS--C) is associated with a favorable course of symptoms (increasing the number of stools, decrease intensity of abdominal pain and bloating) after treatment and IBS--diarrhea (IBS--D) is associated with variable symptoms after treatment (p = 0.031). Using trimebutin or mebeverin in association with other drugs for one month correlates with a favorable evolution of symptoms after treatment and monotherapy is associated with fluctuating symptoms ( p< 0.001). Favorable symptoms are associated with the use of probiotics in combination, but not in monotherapy (p< 0.001). Favorable evolution of symptoms is also associated with the use of anxiolytics in combination. Persistence of symptoms after treatment was correlated with the presence or absence of depression. The absence of depression was correlated with a favorable evolution of symptoms (p = 0.005). IBS-C is associated at limit (marginal significance) with hemorrhoidal disease (p = 0.56). 33 patients (29%)--received monotherapy (trimebutin or mebeverin or probiotics); 81 patients (71%)--received combined therapy: (trimebutin or mebeverin or probiotics) + anxiolytics or proton pump inhibitors (PPI) or nonsteroidal anti-inflammatory (NSAI) or spasmolytics. The most common associated diseases observed in patients with IBS were: depression (27.19%), dyslipidemia (25.43%), hemorrhoidal disease (22.80%) and fibromyalgia (21%).

CONCLUSIONS

The highest response rate was obtained with trimebutin or mebeverin + anxiolitics + probiotics. The most frequent disease associated with IBS was depression. Other diseases with a high incidence: dyslipidemia, hemorrhoidal disease and fibromyalgia. Further studies are needed to analyze the link between IBS and some associated diseases.

Epidemiology of irritable bowel syndrome in the former communist countries from Eastern Europe: a systematic review

Background and aim

The irritable bowel syndrome (IBS) is a functional gastrointestinal disorder frequently encountered in clinical practice in Eastern Europe. Epidemiological data are diverging on this condition. Our objective was to assess the prevalence of IBS in the former communist countries from Eastern Europe (EE).

Methods

We performed a systematic review study using data from PubMed. Many languages, some having only local spreading, are spoken in EE, so we decided to look only for papers indexed in PubMed, which have at least an English summary or title. We searched PubMed using the following keywords: irritable bowel syndrome, functional digestive disorders, prevalence, EE. Only relevant studies were selected for analysis.

Results

From more than 4000 papers retrieved by this search, we identified a few papers appropriate to this survey. The spectrum of prevalence values is wide in IBS. Prevalence of IBS varies in different studies from 28% in a Croatian study, to 14% in Romania. Most studies report a higher prevalence in females. Stressful events are linked to the impairment of symptoms. Anxiety and depression are common in IBS patients, showing similar expression of functional symptoms. Quality of life is impaired. The role of abuse (physical, sexual) is not commonly investigated and when it was, the importance of this factor was revealed to be much less important than in Western Europe or North America. General practitioners seem to be well trained to recognize IBS, to make correct interpretations of the disease and to use the correct therapy. It seems that the Rome criteria are known and applied by general practitioners. Several epidemiological studies on IBS exist in most EE countries. Usually they look for self-reporting symptoms, or reports from endoscopy units. Psychosomatic approach of IBS was taken into consideration in several countries (Poland, Hungary, Romania), mainly by psychologists and psychotherapists rather than by gastroenterologists.

Conclusions

There are few epidemiological studies on the epidemiology of IBS in EE. The majority of studies used Rome criteria. Several studies used small groups of patients. Some of the smaller studies have methodological flaws. The effect of stress and psychological factors are often investigated and analyzed with different methods of different accuracy. Some doctors used knowledge gained in EE in order to disseminate or to investigate further in more economically developed countries with a higher level of health.

Medical nutrition therapy in non-alcoholic fatty liver disease--a review of literature

BACKGROUND AND AIM

Non-alcoholic fatty liver disease (NAFLD) is the most common cause of liver disease worldwide, with a prevalence of 20%-40% in Western populations. The purpose of this article is to review data related to lifestyle changes in patients with NAFLD.

METHOD

We searched a public domain database (PubMed) with the following categories: disease (NAFLD, fatty liver, and non-alcoholic steatohepatitis [NASH]) and intervention (lifestyle intervention, diet, nutrition) with each possible combination through 25 September 2014, for relevant articles. Review of articles was restricted to those published in English. We selected the studies involving adult patients only.

CONCLUSION

There is no consensus as to what diet or lifestyle approach is the best for NAFLD patients. However, patients with NAFLD may benefit from a moderate- to low-carbohydrate (40%-45% of total calories) diet, coupled with increased dietary MUFA and n-3 PUFAs, reduced SFAs. More CRT are needed to clarify the specific effects of different diets and dietary components on the health of NAFLD patients.

ABBREVIATIONS

NAFL = Non-alcoholic fatty liver, NAFLD = non-alcoholic fatty liver disease, NASH = non-alcoholic steatohepatitis, HCC = hepatocarcinoma, BEE = basal energy expenditure, CRT = A small clinical randomized trial showed that short-term carbohydrate restriction is more efficacious in reducing intrahepatic triglyceride, IHT = intrahepatic triglyceride, VLCD = Very low calorie diets, AST = aspartate aminotransferases, SFAs = saturated fatty acids.

[Foreign bodies in the urogenital tract--between iatrogeny and autoerotism]

INTRODUCTION

Our objective was to evaluate the cause, diagnosis and management of foreign bodies in the urogenital tract reviewing a 7 years experience.

MATERIALS AND METHODS

From 2000 to 2007, 12 patients were treated in our department because of foreign bodies localized in the urogenital tract. We retrospectively analyzed the data regarding presentation, diagnosis and management.

RESULTS

The foreign bodies from the urogenital tract included: mascara, spray cap, wires, candle, swabs, plastic tube, remnants from JJ ureteral stent and nefrostomy tube. Diagnostic investigations varied from case to case and consisted of: KUB (kidney, ureter and bladder), abdominal ultrasound, urography, computer tomography, and also cystoscopy. The management was endoscopic in 4 (33%) cases, but in the great majority of them--8 (67.6%) it was necessary a classical intervention.

CONCLUSIONS

Foreign bodies localized in the urogenital tract, represents a relative rare pathology and in many situations those cases have legal implications. Investigations must include radiologic investigations in order to identify their exact location and size. In many cases the management can not be endoscopic and it is necessary a classic intervention.

[The diagnosis and surgical treatment in the case of 2 rare sites of hydatid cyst in children]

In the Clinic of Paediatric surgery of the Hospital "Gr. Alexandrescu" there have been hospitalized and operated 2 cases of hydatic cyst within 1990-1993. The both patients had tumoural structures, one of them being placed on left axillary area (S.E.--11 years old) and the other on the left thigh (M.S.--5 years old). The both patients have been surgically operated, the said tumoural structures being eradicated. The anatomic-pathological examination attested that for the both patients the diagnosis was the hydatic cysts are localized on pulmonary, hepatic or splenic areas, we considered to be interesting to inform you about details of two rare localization of this disease.
