Decade-long trends in the magnitude, treatment, and outcomes of patients aged 30 to 54 years hospitalized with ST-segment elevation and non-ST-segment elevation myocardial infarction

Although acute myocardial infarction (AMI) occurs primarily in the elderly, this disease also affects young adults. Few studies have, however, presented data on relatively young patients hospitalized with AMI. The objectives of this population-based study were to examine recent trends in the magnitude, clinical characteristics, management, and in-hospital and long-term outcomes associated with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI) in patients aged 30 to 54 years. We reviewed the medical records of 955 residents of the Worcester (Massachusetts) metropolitan area aged 30 to 54 years who were hospitalized for an initial STEMI or NSTEMI in 6 biennial periods from 1999 to 2009 at 11 greater Worcester medical centers. From 1999 to 2009, the proportion of young adults hospitalized with an STEMI decreased from approximately 2/3 to 2/5 of all patients with an initial AMI. Patients with STEMI were less likely to have a history of heart failure, hypertension, hyperlipidemia, and kidney disease than those with NSTEMI. Both groups received similar effective medical therapies during their acute hospitalization. In-hospital clinical complications and mortality were low and no significant differences in these end points were observed between patients with STEMI and NSTEMI or with regard to 1-year postdischarge death rates (1.9% vs 2.8%). The present results demonstrate recent decreases in the proportion of relatively young patients diagnosed with an initial STEMI. Patients with STEMI and NSTEMI had similar in-hospital outcomes and long-term survival. Trends in these and other important outcomes warrant continued monitoring.

ASCA IgG and CBir antibodies are associated with the development of Crohn's disease and fistulae following ileal pouch-anal anastomosis

BACKGROUND

For ulcerative colitis (UC) patients undergoing ileal pouch-anal anastomosis (IPAA), postoperative complications include chronic pouchitis and development of Crohn's disease (CD) of the pouch.

AIMS

The aim of this study was to determine if serologic markers obtained postoperatively are associated with the development of complications in UC patients after IPAA.

METHODS

A retrospective chart review was conducted of UC patients with IPAA were tested for expression of serologic markers. Complications abstracted from medical records included postoperative fistula, CD of the pouch, chronic pouchitis, and diversion or excision of the pouch.

RESULTS

142 patients were enrolled, 44 of whom developed complications. Positive serologic profiles for ASCA IgG and anti-CBir1 markers were found to be associated with the development of any complication, (P = 0.017 and P = 0.002, respectively). A positive anti-CBir1 test was also found to be associated with CD of the pouch and/or fistula formation (P < 0.001). Similarly, both ASCA IgG and anti-CBir1 titers were significantly associated with postoperative IPAA complications (P = 0.034 and P = 0.001, respectively), and anti-CBir1 titers were associated with CD of the pouch and/or fistula formation (P < 0.001). Complications developed after a median follow-up of 216 months (range 1-264).

CONCLUSIONS

ASCA IgG and anti-CBir1 markers were associated with the development of complications after IPAA, specifically fistulae and/or CD of the pouch. The ability to identify patients at high risk for adverse outcomes may allow for early aggressive therapy, which may decrease the rate of pouch failure. A prospective study of patients with preoperative serology is ongoing.

Vaccinating the inflammatory bowel disease patient: deficiencies in gastroenterologists knowledge

BACKGROUND

Current therapy for inflammatory bowel disease (IBD) patients often involves agents that suppress the immune system, placing patients at an increased risk for developing infections, of which several are potentially vaccine preventable. Many IBD patients are not being vaccinated appropriately. The aims of this study were to assess gastroenterologist's knowledge regarding vaccinating the IBD patient, eliciting the barriers that prevent vaccinations, and defining the gastroenterologist's role in vaccinations.

METHODS

One thousand gastroenterologists, randomly selected from the membership of the American College of Gastroenterology, were asked to complete a 19 question electronic survey regarding the suitable vaccines for the immunocompetent and immunosuppressed IBD patient and the barriers to recommending the vaccines. The perceived role of the gastroenterologist versus the primary care physician (PCP) was also assessed.

RESULTS

In all, 108 responses were analyzed; 68 (62%) gastroenterologists managed 40+ IBD patients, with 65 (52%) asking their patients about immunization history most or all of the time. The majority believed that the PCP should determine which vaccinations to give (64%) and to administer the vaccines (83%). Overall, 66%-88% of gastroenterologists correctly recommended the inactivated vaccines for their IBD patients not on immunosuppressive therapies while 20%-30% incorrectly recommended administering the live vaccines to their immunosuppressed patients.

CONCLUSIONS

Gastroenterologist knowledge of the appropriate immunizations to recommend to the IBD patient is poor and may be the primary reason why the majority of gastroenterologists believe that the PCP should be responsible for vaccinations. Educational programs on vaccinations directed to gastroenterologists who prescribe immunosuppressive agents are needed.

Preoperative infliximab is not associated with an increased risk of short-term postoperative complications after restorative proctocolectomy and ileal pouch-anal anastomosis

INTRODUCTION

Considerable controversy exists over whether the preoperative use of infliximab (IFX) for refractory ulcerative colitis (UC) increases the risk for surgical complications after restorative proctocolectomy and ileal pouch-anal anastomosis (IPAA). The aim of this study was to assess the association between preoperative IFX use and short-term surgical complications in a single-surgeon cohort at a tertiary care academic center.

METHODS

UC patients who underwent IPAA from September 2005 through May 2009 were retrospectively identified. Twenty-nine patients treated with IFX within 12 weeks of surgery and 52 non-IFX control subjects were identified. Short-term postoperative outcomes were compared between groups occurring within 30 days of loop ileostomy closure.

RESULTS

Patients were similar with respect to demographics, co-morbidities, rate of emergency surgery, hand-sewn anastomosis, and preoperative use of cyclosporine, azathioprine, and high-dose steroids. IFX patients were more likely to have received a laparoscopic hand-assisted IPAA, low-, medium-, and any-dose steroids, 6-mercaptopurine (6-MP), methotrexate, and to have failed medical therapy. There was no short-term mortality. Overall postoperative and infectious complications were similar between IFX and non-IFX groups. Multivariate regression models revealed no independent predictors for postoperative complications when including IFX [odds ratio (OR) 0.78, p = 0.67], laparoscopic hand-assisted IPAA, 6-MP, methotrexate, steroids, failure of medical therapy, and body mass index.

CONCLUSIONS

Preoperative IFX use was not associated with an increased risk of short-term postoperative complications after IPAA.
