Inflammatory Bowel Disease in Older People

Clinical results following colonic resection for ulcerative colitis in elderly individuals (elderly-onset vs. nonelderly onset)

BACKGROUND

The incidence of ulcerative colitis (UC) is increasing, but there are few reports comparing elderly UC patients undergoing colectomy for elderly-onset UC (EO) and nonelderly-onset UC (NEO). The aim of this study was to analyze the differences between EO and NEO patients who underwent UC-related surgery.

METHODS

We identified 1973 patients with UC who underwent colectomy at Hyogo College of Medicine between January 1, 1984, and December 31, 2018. Only patients aged 65 years old and older who underwent colectomy were enrolled in this study (n = 221, 11.2%), and their clinical records were retrospectively reviewed. Patients were divided into two groups according to their age at disease onset: those with onset at younger than 60 years old (NEO) and at 60 years old or older (EO).

RESULTS

In the 221 UC patients who underwent colectomy at 65 years old or older, there were 155 cases of EO and 66 cases of NEO. The main surgical indication in NEO patients was colitis-associated cancer/dysplasia (32/66, 47%). In contrast, refractory to medical treatment was the leading cause of surgery in EO patients (80/155, 52%). The distributions of surgical indications were different between the two groups (p < 0.01). The preoperative daily dose of steroids was significantly higher in the EO group than in the NEOgroup (0 mg vs. 10 mg, p < 0.01). The rates of immunosuppressant, infliximab (IFX) and adalimumab use did not differ significantly between the groups. Significantly more patients underwent emergency surgery in the EO group than in the NEO group (14% vs. 35%, p < 0.01). The proportions of patients with postoperative morbidity (Clavien-Dindo grade III or higher) were 17.4% (27/155) in the EO group and 13.6% (9/66) in the NEO group. There was no significant difference between the two groups (p = 0.48). The prognosis of the EO patients who underwent UC-related emergency surgery was worse than that of the NEO patients (p < 0.01). In the EO group, 8 (14.8%) of 54 patients died within 30 postoperative days, while there were no deaths in the NEO group.

CONCLUSION

Among elderly UC patients undergoing UC-related surgery, EO patients undergoing emergency surgery had very poor outcomes, and the mortality rate was 14.8%. In such cases, it is important for physicians and surgeons to begin communication at an early stage so that the optimal surgical timeframe is not missed.

Analysis of Hospital-Based Emergency Department Visits for Inflammatory Bowel Disease in the USA

BACKGROUND

Inflammatory bowel disease (IBD) is a chronic, debilitating condition with high emergency department (ED) utilization. We aimed to investigate the utilization patterns of ED by IBD patients and measure hospitalization and surgical rates following ED visits.

METHODS

We conducted a cross-sectional study of adults with IBD listed as the primary ED diagnosis from the 2009 to 2011 Nationwide Emergency Department Sample. The characteristics of the IBD-related ED visits in relation to following hospitalizations and surgeries were analyzed.

RESULTS

Adult IBD patients constitute 0.09 % of the total ED visits. Crohn's disease (CD) contributed to 69 % of the IBD-ED visits. The hospitalization rate from ED was 59.9 % nationally, ranging from 56 % in west to 69 % in northeast. The most significant factors associated with hospitalization were intra-abdominal abscess [odds ratio (OR) 24.22], bowel obstruction (OR 17.77), anemia (OR 7.54), malnutrition (OR 6.29), hypovolemia/electrolyte abnormalities (OR 5.57), and fever/abnormal white cell count (OR 3.18). Patients with CD (OR 0.66), low-income group (OR 0.90), and female gender (OR 0.87) have a lower odds of getting hospitalized. Age above 65 years (OR 1.63), CD (OR 1.89), bowel obstruction (OR 9.24), and intra-abdominal abscess (OR 18.41) were significantly associated with surgical intervention.

CONCLUSION

The IBD-related ED visits have remained relatively stable from 2009 to 2011. The presence of anemia, malnutrition, hypovolemia, electrolyte abnormalities, fever, abnormal white cell count, bowel obstruction, or intra-abdominal abscess during the ED visit was associated with hospitalization. The presence of bowel obstruction and intra-abdominal abscess was strongly associated with surgical intervention.

Systematic review with meta-analysis: inflammatory bowel disease in the elderly

BACKGROUND

Elderly patients represent an increasing proportion of the inflammatory bowel disease (IBD) population.

AIM

To critically review available data regarding the care of elderly IBD patients.

METHODS

Bibliographic searches (MEDLINE) up to June 2013.

RESULTS

Approximately 10-15% of cases of IBD are diagnosed in patients aged >60 years, and 10-30% of the IBD population are aged >60 years. In the elderly, IBD is easily confused with other more common diseases, mainly diverticular disease and ischaemic colitis. The clinical features of IBD in older patients are generally similar to those in younger patients. Crohn's disease (CD) in elderly patients is characterised by its predominantly colonic localisation and uncomplicated course. Proctitis and left-sided ulcerative colitis are more common in patients aged >60 years. Infections are associated with age and account for significant mortality in IBD patients. The treatment of IBD in the elderly is generally similar. However, the therapeutic approach in the elderly should be 'start low-go slow'. The benefit of thiopurines in older CD patients remains debatable. Although the indications for anti-tumour necrosis factors in the elderly are generally similar to those for younger patients, lower response and higher adverse events have been reported in the elderly. Surgery in elderly patients does not generally differ. Ileal pouch-anal anastomosis can be successful, provided the patient retains good anal sphincter function.

CONCLUSIONS

Management of the older IBD patient differs from that of younger patients; therefore, conventional practice algorithms may have to be modified to account for advanced age.

Inflammatory bowel disease in the elderly is associated with worse outcomes: a national study of hospitalizations

BACKGROUND

Inflammatory bowel disease (IBD) has a bimodal peak of incidence with approximately 15% of the cases manifesting after 65 years. Previous reports on the outcomes of IBD in the elderly have been single-center studies or have predated the use of biologics. The aim of our study was to compare outcomes of IBD-related hospitalizations in a nationwide representative cohort of patients 65 years and older with younger patients.

METHODS

This was a cross-sectional study utilizing data from the Nationwide Inpatient Sample (NIS) for the year 2004. We identified all IBD-related hospitalizations through the presence of the appropriate ICD-9-CM codes for Crohn's disease, ulcerative colitis, or associated complications. We compared the differences in disease presentation as well the frequency of utilization of different interventions. We calculated the adjusted odds of mortality in older compared to the younger IBD patients using multivariate logistic regression.

RESULTS

Patients older than 65 years accounted for approximately 25% of all IBD-related hospitalizations in 2004. They were less likely to be hospitalized with fistulizing (4.0 versus 8.8%, P < 0.001) or stricturing disease (4.0 versus 5.8%, P = 0.001). Even after adjusting for comorbidity, they had higher in-hospital mortality (odds ratio [OR] 3.91, 95% confidence interval [CI] 2.50-6.11). Older patients with fistulizing disease are more likely to undergo surgery (OR 1.55, 95% CI 1.00-2.40). Among IBD patients who underwent surgery, older patients also had a longer postoperative stay (1.73 days, 95% CI 1.04-2.21).

CONCLUSIONS

Older patients with IBD-related hospitalizations have substantial morbidity and higher mortality than younger patients. Further research is needed to better characterize the natural history and treatment outcomes in this cohort.

Abdominal surgery in the older Crohn's population

BACKGROUND

The surgical literature perceives that the elderly cohort of Crohn's patients may have increased risk with surgery.

METHODS

A retrospective review and prospective database analysis of all patients with histologically proven Crohn' s disease who had a laparotomy at a single Sydney teaching hospital were performed. The last laparotomy of each patient was included in the analysis for morbidity and mortality to assess whether an older cohort was at an increased risk.

RESULTS

A total of 156 patients had 298 laparotomies for histopathologically proven Crohn's disease. The frequency distribution of age at last laparotomy was bimodal, and the statistically determined cut-off age between younger and older cohorts was 55 years. Thirty-three patients were older than 55 years. There was no difference in duration of symptoms before first diagnosis (older, 17 months vs younger, 25 months), previous number of Crohn's operations (42.4 vs 39.8%), or duration of known Crohn's disease. Isolated large bowel disease was more common in the elderly cohort (42.4 vs 18.7%, chi2 = 8.09, P < 0.01). Small bowel and ileocaecal resections were more common in the younger cohort (72.4 vs 51.6%, chi2 = 5.19, P < 0.025). There was one death in each cohort (overall mortality 1.3%) and anastomotic leak rates (defined as the number of leaks per number of patients with anastomoses), were 4.3% (older) vs 5.3% (younger) despite frank sepsis present in 21.2% of all subjects at the time of surgery. The older group had more cardiac (18.2 vs 0.8%, P < 0.001) and respiratory complications (18.2 vs 2.4%; P = 0.0003) and a longer mean but not median postoperative hospital admission.

CONCLUSIONS

In conclusion, clinical features and presentation are similar in the older and younger Crohn's patients having a laparotomy. However, in the older patient there is a greater likelihood of large bowel disease, ileocaecal resection is done less commonly, there is a higher risk of minor cardiopulmonary postoperative complications, but with similar mortality and anastomotic leak rates to the younger patient.

Inflammatory bowel disease in older patients

The onset of UC and CD may occur later in life. Although making the diagnosis of IBD in the elderly can be challenging, the clinical course, natural history, and response to treatment are similar for older and younger patients. In fact, both UC and CD tend to be less extensive in older patients, a feature that may contribute to the overall favorable prognosis for elderly patients with IBD. Overall mortality rates for both UC and CD appear to be similar to that of the general population except for those few patients that present with severe initial disease. Typical features of IBD in the elderly are summarized in Table 3. The differential diagnosis of IBD in the elderly includes infectious causes of enterocolitis, ischemic colitis, and diverticular disease as well as several other mimics of IBD. Awareness of the possibility of late-onset disease and the unique manifestations of disease in the elderly contributes to accurate diagnosis and timely treatment.
