Autoimmune gastrointestinal complications in patients with systemic lupus erythematosus: case series and literature review. Lupus 2016; 25:1509-1519. [PMID: 27329649 DOI: 10.1177/0961203316655210] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2015] [Accepted: 05/25/2016] [Indexed: 02/06/2023]
Abstract
The association of systemic lupus erythematosus (SLE) with gastrointestinal autoimmune diseases is rare, but has been described in the literature, mostly as case reports. However, some of these diseases may be very severe, thus a correct and early diagnosis with appropriate management are fundamental. We have analysed our data from the SLE patient cohort at University College Hospital London, established in 1978, identifying those patients with an associated autoimmune gastrointestinal disease. We have also undertaken a review of the literature describing the major autoimmune gastrointestinal pathologies which may be coincident with SLE, focusing on the incidence, clinical and laboratory (particularly antibody) findings, common aetiopathogenesis and complications.

Computed tomography in patients with abdominal pain and diarrhoea: does the benefit outweigh the drawbacks? Intern Med J 2013; 43:1141-4. [PMID: 24134171 DOI: 10.1111/imj.12262] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2012] [Accepted: 05/20/2013] [Indexed: 12/25/2022]
Abstract
The role of computed tomography (CT) in the evaluation of abdominal pain is well established. However, concern exists in regard to procedure-related radiation levels, contrast-medium toxicity and costs. We sought to determine whether the use of abdominal CT caused major changes in the management of patients who had abdominal pain and diarrhoea. We reviewed all abdominal CT examinations that were performed at our hospital from October through December 2010. We selected 574 scans that had been performed in patients who presented with or without diarrhoea. We examined the selected medical records to determine whether the CT scan changed patients' management. A scan was considered to be management changing if a decisive intervention occurred on the basis of the scan results. Among 124 scans in patients with diarrhoea and 450 scans in patients without diarrhoea, the scan results changed management in 13 of the patients with diarrhoea (11%) and in 233 of those without diarrhoea (52%) (P < 0.001). When management changed, the changes resulted from findings unrelated to diarrhoea. Despite its defined role in the assessment of abdominal pain, CT of patients that also had diarrhoea seldom caused a major change in management. The probability of CT causing such a change does not outweigh the cost, radiation risk or potential for contrast-induced nephropathy.

Abstract
We present the first imaging report of perforated appendicitis in an umbilical hernia. Computed tomography demonstrated a gas-forming abscess within an umbilical hernia and the cecum was found inside the hernial sac, with an inner relation to the abscess. Computed tomographic findings suggested appendicitis as possible diagnosis, which was confirmed at surgery. Physicians must consider appendicitis within the differential diagnosis of an abdominal abscess located near to the cecum, even at an unexpected location.

Abstract
The objectives of this study were to determine the prevalence of use of abdominal computed tomography (CT) in older ED patients with acute nontraumatic abdominal pain, describe the most common diagnostic CT findings, and determine the proportion of diagnostic CT results. This was a prospective, observational, multicenter study of 337 patients 60 years or older. History was obtained prospectively; charts were reviewed for radiographic findings, dispositions, diagnoses, and clinical course, and patients were followed up at 2 weeks for additional information. The prevalence of use of abdominal CT was 37%. The most common diagnostic findings were diverticulitis (18%), bowel obstruction (18%), nephrolithiasis (10%), and gallbladder disease (10%). Eight percent of patients had findings suggestive of neoplasm. Overall, 57% of CT results were diagnostic (95% confidence interval [CI], 49%-66%), 75% (95% CI, 63%-84%) for patients requiring acute medical or surgical intervention, and 85% (95% CI, 62%-97%) for patients requiring acute surgical intervention. CT use is highly prevalent in older ED patients with acute abdominal pain. CT results are often diagnostic, especially for patients with emergent conditions.

Abstract
The objective of the study was to measure the utilization and diagnostic value of tests used in the Emergency Department (ED) on patients with undifferentiated non-traumatic abdominal or flank pain. Specific goals were to measure how often these tests led to changes in diagnosis or disposition, which tests were most commonly used, and which tests providers considered most helpful. We conducted a pilot single-center, prospective descriptive study, enrolling all eligible adult patients who presented to our ED with non-traumatic abdominal or flank pain during defined hours of our intake period. Based on serial provider interviews pre- and post-testing, we measured the frequency of change of most likely diagnosis and disposition, which tests were performed, and the provider-perceived value of tests. We enrolled 124 subjects with a mean age of 44 years; 27% were admitted. Testing led to a change in most likely diagnosis in 37% of subjects, and in disposition in 41%. Frequency of diagnostic test use varied from a high of 93% for CBC to 6% for a blood or urine culture. Overall, 65% of patients had at least one imaging study performed, and 39% had an abdominal/pelvic computed tomography (CT) scan. Over all subjects, providers identified the most useful tests as the CT scan (31%) and urinalysis (17%). In conclusion, among ED patients who presented with non-traumatic abdominal or flank pain to one academic center, the pre-test most likely diagnosis and disposition were changed based on the ED evaluation in over one-third of subjects. Almost all received blood tests and two-thirds received one or more imaging studies. Based on providers' subjective opinions, the most valuable tests were the abdomino/pelvic CT scan and the urinalysis.

Abstract
BACKGROUND To determine whether intravenous contrast improves the ability of radiologists to establish the cause of acute abdominal pain after nondiagnostic or normal unenhanced CT. METHODS Out of 164 consecutive emergency department patients presenting with less than 48 h of nontraumatic, acute abdominal pain, a confident diagnosis for cause of pain was made prospectively in 71/164 (43%) patients on these unenhanced scans by the monitoring radiologist. In the other 93 patients, our study sample, intravenous contrast-enhanced CT was obtained. At a later date, retrospectively, two experienced abdominal CT radiologists independently evaluated unenhanced CT scans alone for potential causes of pain and diagnostic confidence level on a 1-3 scale. At least 2 weeks later, intravenous enhanced and unenhanced scans were read side-by-side for the same assessment. RESULTS There was no significant difference in diagnostic confidence levels comparing unenhanced CT alone (2.59) vs. intravenous enhanced and unenhanced CT together (2.64). Chi-square analysis found no significant difference in finding a cause for pain when intravenous contrast was added compared to the initial unenhanced scan alone. CONCLUSIONS Intravenous contrast did not significantly improve the ability of CT to establish a cause of abdominal pain after a negative or nondiagnostic unenhanced CT.

Abstract
AIM To determine the impact of computed tomography (CT) on the diagnosis and treatment plan in patients with acute abdominal pain. MATERIALS AND METHODS A prospective study was undertaken in 125 adult patients presenting with acute abdominal pain (74 men and 51 women; 40.2 +/- 19.3 years; range, 18-92). Changes in diagnosis, gain in percentage diagnostic certainty and changes of treatment plan of the surgeons in the emergency department before and after CT were evaluated. Pre- and post-CT diagnoses were compared with the final diagnoses. RESULTS CT findings changed the initial diagnosis in 40 (32.0%) patients. The diagnostic certainty was 58.3 +/- 22.9% before CT, and its gain after CT was 21.9 +/- 18.5 points (P < 0.0001). Post-CT diagnoses were consistent with the final diagnosis in 116 patients (92.8%), while pre-CT diagnoses were correct in 89 patients (71.2%; P < 0.0001). Initial treatment plans were changed in 31 (24.8%) patients after CT. In 57 (45.6%) patients, CT information changed diagnoses and/or treatment plans. No significant differences were observed in the diagnosis, diagnostic certainty and treatment plan among four surgeons. CONCLUSION Contrast-enhanced CT frequently changed the clinical diagnoses with increased diagnostic certainty and the initial treatment plans.

Abstract
OBJECTIVE The purpose of this study is to document the impact of CT performed in the emergency department of patients presenting with nontraumatic acute abdominal pain. SUBJECTS AND METHODS Fifty-seven patients were enrolled in this prospective study. Using a computer order entry system, emergency department physicians were required to report their most likely diagnosis, level of certainty, and management plan for their patients before ordering abdominal CT. After CT was performed, each physician was required to provide again his or her diagnosis, level of diagnostic certainty, and treatment plan. The outcome of each patient was evaluated by either surgery, other imaging studies, or clinical follow-up. RESULTS After the abdominal CT, physicians' mean level of certainty in their diagnoses increased by 1.5 points (on a five-point scale; p < 0.0001). Patient management was changed in 33 (60.0%) of 55 patients. Planned treatment before CT was admission in 42 patients. Actual admissions after CT totaled 32 patients (excluding the two patients in whom preimaging information was not recorded). Thus, the net effect of abdominal CT scanning was to avert 10 (23.8%) of 42 hospital admissions. CONCLUSION CT performed in the emergency department increases the physician's level of certainty, reduces hospital admission rates by 23.8%, and leads to more timely surgical intervention.

Plain abdominal radiographs and abdominal CT scans for nontraumatic abdominal pain--added value? Am J Emerg Med 1999; 17:668-71.

Abstract
We conducted a retrospective descriptive study to determine the value of plain abdominal radiographs in emergency department (ED) patients also receiving abdominal computed tomography scans (CT) for the evaluation of nontraumatic abdominal, back and flank pain (NTAP). Cases were identified through radiology log books. Medical records and radiology reports were reviewed to determine whether the CT confirmed the findings of the plain abdominal radiographs, and whether the clinical course confirmed the results of either. Test characteristics for the plain abdominal radiograph and for the CT, using the clinical course including subsequent invasive procedures as the gold standard, were calculated. Of 177 patients who received CTs, 97 (55%) also received plain abdominal radiographs. Among the 74 patients who were admitted to the hospital and had complete data, the sensitivity and specificity for the plain abdominal radiographs were .43 and .75 respectively, compared to .91 and .94 for the CT scan (P(sens.) < .05, P(spec.) < .05). In 4 patients (5%), both studies failed to identify pathology shown in a subsequent procedure. In ED patients with NTAP, the plain abdominal radiograph may have some value as a screening tool; however, in patients in whom a CT is likely to be ordered anyway, a plain abdominal radiograph is unhelpful and often misleading.

Abstract
PURPOSE To evaluate the computed tomographic (CT) features of systemic lupus erythematosus (SLE) in patients with acute abdominal pain. Special emphasis was placed on the analysis of ischemic bowel disease. MATERIALS AND METHODS The authors retrospectively reviewed the images from 39 abdominal CT examinations performed in 33 patients with SLE and acute abdominal pain. Images were evaluated for bowel wall changes, mesenteric changes, fluid collection, retroperitoneal lymphadenopathy, peritoneal enhancement, and hepatomegaly as well as for changes in other abdominal organs. Ischemic bowel disease was diagnosed if at least three of the following signs were seen: bowel wall thickening, target sign, dilatation of intestinal segments, engorgement of mesenteric vessels, and increased attenuation of mesenteric fat. RESULTS Thirty-one (79%) of the 39 examinations had CT findings diagnostic of ischemic bowel disease, including symmetric bowel wall thickening (n = 29), target sign (n = 26), and mesenteric vascular engorgement and haziness (n = 31). In 24 cases, bowel wall thickening was multifocal, with variable length, and did not appear to be confined to a single vascular territory. CONCLUSION The most common CT finding in patients with SLE and acute abdominal pain is ischemic bowel disease. CT is useful for detecting the primary cause of gastrointestinal symptoms, planning treatment, and monitoring for infarction or perforation.

Abstract
OBJECTIVES The purposes of this study were to investigate the use of computed tomography (CT) imaging in patients with suspected acute appendicitis and to evaluate the impact of CT on negative appendectomy and perforation rates. In patients clinically diagnosed of acute appendicitis the reported overall negative appendectomy rate is about 15-20%; 10% in men and 25-45% in women of childbearing age. This is associated with a perforation rate of 21-23%. METHODS This is a retrospective analysis of 146 consecutive patients presenting with clinical symptoms suspicious of appendicitis over a 2-yr period in whom CT examinations were performed before therapy was instituted. The overall negative appendectomy and perforation rates were calculated for the entire group, as well as for the 54 women aged 15-50 yr in the childbearing cohort. RESULTS The negative appendectomy rate was 4% in 122 patients operated on and the perforation rate was 22%. Among 36 women 15-50 yr of age operated on, the negative appendectomy rate was 8.3% and the perforation rate was 19%. Surgery was avoided in 24 patients, 18 of whom were women of childbearing age. CONCLUSIONS The judicious use of CT imaging in patients with equivocal clinical presentation suspected of having appendicitis led to a significant improvement in the preoperative diagnosis. It resulted in a substantial decrease in the negative appendectomy rate compared to previously published reports, without incurring an increase in the perforation rate.

Abstract
Abdominal complaints are common in the HIV-infected patient, and the signs and symptoms of disease may be masked by concurrent illness and a weak immune response, making accurate diagnosis difficult. Patients with acquired immunodeficiency syndrome (AIDS) are susceptible to diseases common to the general population; however, their generalized state of immunodeficiency places them at increased risk for many unusual disorders, predominately infectious and neoplastic. Radiologic evaluation, in particular, computed tomography (CT) with its ability to image the entire abdomen and pelvis, plays a crucial role in the prompt and accurate diagnosis and treatment of these patients.
