RESUMO

BACKGROUND: A unique enzootic focus of Mycobacterium bovis in free-ranging deer was identified in northern lower Michigan in 1994, with subsequent evidence of transmission to local cattle herds. Between 2002 and 2017, 3 Michigan deer hunters with M. bovis disease were previously reported. We present 4 additional human cases linked to the zoonotic focus in deer, utilizing genomic epidemiology to confirm close molecular associations among human, deer and cattle M. bovis isolates. METHODS: Identification of human tuberculosis (TB) cases with cultures of M. bovis was provided from the Michigan Department of Health and Human Services (MDHHS) tuberculosis database. Clinical review and interviews focused on risk factors for contact with wildlife and cattle. Whole genome sequences of human isolates were compared with a veterinary library of M. bovis strains to identify those linked to the enzootic focus. RESULTS: Three confirmed and 1 probable human case with M. bovis disease were identified between 2019 and 2022, including cutaneous disease, 2 severe pulmonary disease cases, and human-to-human transmission. The 3 human isolates had 0-3 single-nucleotide polymorphisms (SNPs) with M. bovis strains circulating in wild deer and domestic cattle in Michigan. CONCLUSIONS: Spillover of enzootic M. bovis from deer to humans and cattle continues to occur in Michigan. Future studies should examine the routes of transmission and degree of risk to humans through expanded epidemiological surveys. A One Health approach linking human, veterinary and environmental health should address screening for TB infection, public education, and mitigation of transmission.

RESUMO

BACKGROUND: Multiple studies have demonstrated that when incorporated with conventional imaging modalities, cardiac F-18 PET/CT can aid in diagnosis of endocarditis and improve the sensitivity of the Duke Criteria. These studies used as their gold standard the opinion of an endocarditis team and were characterized by low percentages of patients who underwent surgery. We reviewed 4 years of surgically managed IE cases where F-18 cardiac PET/CT was used to aid diagnosis. METHODS: Between July 2014 and December 2018, we retrospectively reviewed 68 surgically managed endocarditis cases to identify patients who underwent pre-operative PET scans. RESULTS: Fourteen patients were identified who underwent F-18 cardiac PET/CT prior to surgical intervention. Nine cases were classified as possible endocarditis by Duke Criteria and 8 involved prosthetic valves. Twelve out of fourteen scans were interpreted as suggestive of or consistent with endocarditis based on FDG uptake. Twelve positive PETs were associated with either operative findings of infection and/or positive PCR testing on the excised valve. Two patients with negative scans were found to have non-infectious mobile masses intra-operatively, negative valve cultures and negative pathology. CONCLUSION: In a small cohort, F-18 FDG cardiac PET/CT correlated closely with intra-operative findings in patients with endocarditis and helped guide surgical decision-making. It could be considered for addition to the Duke Criteria in the American Heart Association endocarditis guidelines similar to European protocols.

RESUMO

BACKGROUND: During the initial months of the COVID-19 pandemic, rapidly rising disease prevalence in the United States created a demand for patient-facing information exchanges that addressed questions and concerns about the disease. One approach to managing increased patient volumes during a pandemic involves the implementation of telephone-based triage systems. During a pandemic, telephone triage hotlines can be employed in innovative ways to conserve medical resources and offer useful population-level data about disease symptomatology and risk factor profiles. OBJECTIVE: The aim of this study is to describe and evaluate the COVID-19 telephone triage hotline used by a large academic medical center in the midwestern United States. METHODS: Michigan Medicine established a telephone hotline to triage inbound patient calls related to COVID-19. For calls received between March 24, 2020, and May 5, 2020, we described total call volume, data reported by callers including COVID-19 risk factors and symptomatology, and distribution of callers to triage algorithm endpoints. We also described symptomatology reported by callers who were directed to the institutional patient portal (online medical visit questionnaire). RESULTS: A total of 3929 calls (average 91 calls per day) were received by the call center during the study period. The maximum total number of daily calls peaked at 211 on March 24, 2020. Call volumes were the highest from 6 AM to 11 AM and during evening hours. Callers were most often directed to the online patient portal (1654/3929, 42%), nursing hotlines (1338/3929, 34%), or employee health services (709/3929, 18%). Cough (126/370 of callers, 34%), shortness of breath (101/370, 27%), upper respiratory infection (28/111, 25%), and fever (89/370, 24%) were the most commonly reported symptoms. Immunocompromised state (23/370, 6%) and age >65 years (18/370, 5%) were the most commonly reported risk factors. CONCLUSIONS: The triage algorithm successfully diverted low-risk patients to suitable algorithm endpoints, while directing high-risk patients onward for immediate assessment. Data collected from hotline calls also enhanced knowledge of symptoms and risk factors that typified community members, demonstrating that pandemic hotlines can aid in the clinical characterization of novel diseases.

RESUMO

BACKGROUND: The primary objective of this study was to compare the characteristics of culture-positive and culture-negative status in septic patients. We also determined whether culture status is associated with mortality and whether unique variables are associated with mortality in culture-positive and culture-negative patients separately. METHODS: Utilizing patient records from intensive care units, emergency department, and general care wards in a large academic medical center, we identified adult patients with suspected infection and ≥2 systemic inflammatory response syndrome criteria between January 1, 2007, and May 31, 2014. We compared the characteristics between culture-positive and culture-negative patients and used binary logistic regression to identify variables independently associated with culture status and mortality. We also did sensitivity analyses using patients with Sequential Organ Failure Assessment and quick Sequential Organ Failure Assessment criteria for sepsis. RESULTS: The study population included 9288 culture-negative patients (89%) and 1105 culture-positive patients (11%). Culture-negative patients received more antibiotics during the 48 hours preceding diagnosis but otherwise demonstrated similar characteristics as culture-positive patients. After adjusting for illness severity, a positive culture was not independently associated with mortality (odds ratio = 1.01 [95% CI, 0.81-1.26]; P = .945). The models predicting mortality separately in culture-negative and culture-positive patients demonstrated very good and excellent discrimination (C-statistic ± SD, 0.87 ± 0.01 and 0.92 ± 0.01), respectively. In the sensitivity analyses using patients with sepsis by Sequential Organ Failure Assessment and quick Sequential Organ Failure Assessment criteria, after adjustments for illness severity, positive cultures were still not associated with mortality (odds ratio = 1.13 [95% CI, 0.86-1.43]; P = .303; and odds ratio = 1.05 [95% CI, 0.83-1.33]; P = .665), respectively. In all models, physiological derangements were associated with mortality. CONCLUSIONS: While culture status is important for tailoring antibiotics, culture-negative and culture-positive patients with sepsis demonstrate similar characteristics and, after adjusting for severity of illness, similar mortality. The most important factor associated with negative cultures is receipt of antibiotics during the preceding 48 hours. The risk of death in patients suspected of having an infection is most associated with severity of illness. This is aligned with the Sepsis-3 definition using Sequential Organ Failure Assessment score to better identify those suspected of infection at highest risk of a poor outcome.

RESUMO

OBJECTIVES: Interdisciplinary communication at a Veterans Affairs (VA) academic teaching hospital is largely dependent on alphanumeric paging, which has limitations as a result of one-way communication and lack of reliable physician identification. Adverse patient outcomes related to difficulty contacting the correct consulting provider in a timely manner have been reported. METHODS: House officers were surveyed on the level of satisfaction with the current VA communication system and the rate of perceived adverse patient outcomes caused by potential delays within this system. Respondents were then asked to identify the ideal paging system. These results were used to develop and deploy a new Web site. A postimplementation survey was repeated 1 year later. This study was conducted as a quality improvement project. RESULTS: House officer satisfaction with the preintervention system was 3%. The majority used more than four modalities to identify consultants, with 59% stating that word of mouth was a typical source. The preferred mode of paging was the university hospital paging system, a Web-based program that is used at the partnering academic institution. Following integration of VA consulting services within the university hospital paging system, the level of satisfaction improved to 87%. Significant decreases were seen in perceived adverse patient outcomes (from 16% to 2%), delays in patient care (from 90% to 16%), and extended hospitalizations (from 46% to 4%). CONCLUSIONS: Our study demonstrates significant improvement in physician satisfaction with a newly implemented paging system that was associated with a decreased perceived number of adverse patient events and delays in care.

RESUMO

INTRODUCTION: Poor prescribing is probably the most common cause of preventable medication errors and many of these events involve junior doctors. In 2009, an electronic problem-based therapeutics course developed at the University of Michigan Medical School (UMMS) was translated and adapted for use at the University of Zagreb Medical School (UZMS). METHODS: After students from both schools took the course in 2010, we compared their responses with an online questionnaire addressing the course quality and its effectiveness. RESULTS: There were no statistically significant differences in the overall average grades awarded for the course (UZMS 4.11 ± 0.86 vs. UMMS 3.96 ± 0.93; 95% CI mean difference (MD) -0.36, 0.07; P = 0.175) with both student groups expressing high satisfaction rates with its quality, accessibility and overall design. UZMS students reported spending less time working through the course than their American colleagues (2.14 ± 1.01 vs. 2.89 ± 1.02 on a five point Likert scale; 95% CI MD 0.51, 0.99; P < 0.05). Furthermore, Croatian students indicated greater difficulty with course materials (3.54 ± 0.59 vs. 3.25 ± 0.59; 95% CI MD -0.42, -0.15; P < 0,05) and weekly multiple choice questions (3.83 ± 0.62 vs. 3.4 ± 0.61; 95% CI MD -0.58, -0.29; P < 0,05) compared with the UMMS students. CONCLUSION: It is possible to adapt and translate successfully whole online teaching resources and implement them internationally in different countries and health care systems, achieving similar, high student satisfaction rates while decreasing administrative and cost burdens. Web based learning may have great potential to offer a cost effective and safe environment in which prescribing skills can be improved.

RESUMO

OBJECTIVE: To describe the natural course of procalcitonin (PCT) in patients with coronavirus disease 2019 (COVID-19) and the correlation between PCT and antimicrobial prescribing to provide insight into best practices for PCT data utilization in antimicrobial stewardship in this population. DESIGN: Single-center, retrospective, observational study. SETTING: Michigan Medicine. PATIENTS: Inpatients aged ≥18 years hospitalized March 1, 2020, through October 31, 2021, who were positive for severe acute respiratory coronavirus virus 2 (SARS-CoV-2), with ≥1 PCT measurement. Exclusion criteria included antibiotics for nonpulmonary bacterial infection on admission, treatment with azithromycin only for chronic obstructive pulmonary disease (COPD) exacerbation, and pre-existing diagnosis of cystic fibrosis with positive respiratory cultures. METHODS: A structured query was used to extract data. For patients started on antibiotics, bacterial pneumonia (bPNA) was determined through chart review. Multivariable models were used to assess associations of PCT level and bPNA with antimicrobial use. RESULTS: Of 793 patients, 224 (28.2%) were initiated on antibiotics: 33 (14.7%) had proven or probable bPNA, 125 (55.8%) had possible bPNA, and 66 (29.5%) had no bPNA. Patients had a mean of 4.1 (SD, ±5.2) PCT measurements if receiving antibiotics versus a mean of 2.0 (SD, ±2.6) if not. Initial PCT level was highest for those with proven/probable bPNA and was associated with antibiotic initiation (odds ratio 95% confidence interval [CI], 1.17-1.30). Initial PCT (rate ratio [RR] 95% CI, 1.01-1.08), change in PCT over time (RR 95% CI, 1.01-1.05), and bPNA group (RR 95% CI, 1.23-1.84) were associated with antibiotic duration. CONCLUSIONS: PCT trends are associated with the decision to initiate antibiotics and duration of treatment, independent of bPNA status and comorbidities. Prospective studies are needed to determine whether PCT level can be used to safely make decisions regarding antibiotic treatment for COVID-19.

RESUMO

INTRODUCTION: Osteomyelitis is associated with significant morbidity, including amputation. There are limited data on long-term amputation rates following an osteomyelitis diagnosis. We sought to determine the incidence of amputation in patients with osteomyelitis over 2 years. RESEARCH DESIGN AND METHODS: Observational cohort study of 1186 inpatients with osteomyelitis between 2004 and 2015 and stratified by osteomyelitis location status to evaluate the impact on amputation, mortality rates, readmission data, and inpatient days. RESULTS: Persons with diabetes had 3.65 times greater probability of lower extremity amputation (p<0.001), readmission (p<0.001), and longer inpatient stay (p<0.001) and had higher 2-year mortality (relative risk (RR) 1.23, p=0.0027), adjusting for risk factors. Male gender (RR 1.57, p<0.001), black race (RR 1.41, p<0.05), former smoking status (RR 1.38, p<0.01), myocardial infarction (RR 1.72, p<0.001), congestive heart failure (RR 1.56, p<0.001), peripheral vascular disease (RR 2.25, p<0.001) and renal disease (RR 1.756, p<0.001) were independently associated with amputation. Male gender (RR 1.39, p<0.01), black race (RR 1.27, p<0.05), diabetes (RR 2.77, p<0.001) and peripheral vascular disease (RR 1.59, p<0.001) had increased risk of lower, not upper, extremity amputation. CONCLUSIONS: Patients with osteomyelitis have higher rates of amputation and hospitalization. Clinicians must incorporate demographic and comorbid risk factors to protect against amputation.

RESUMO

Diffuse infiltrative lymphocytosis syndrome (DILS) arises in HIV-positive patients secondary to infiltration of lymphocytes into the peripheral tissues and produces the disease's characteristic symptoms-parotid gland enlargement and a sicca syndrome. Many patients, however, first seek medical attention for treatment of the extraglandular manifestations of DILS, most commonly interstitial pneumonitis. In this case report, we describe an atypical presentation of DILS characterized by polyradiculoneuropathy in the absence of parotid gland enlargement or interstitial pneumonitis. Minor salivary gland biopsy of the patient's lip confirmed a chronic inflammatory state with lymphoid aggregates within the minor salivary glands. He was started on prednisone with immediate improvement in his symptoms. This report illustrates for clinicians the diverse extraglandular manifestations of DILS and underscores the importance of considering it in the differential diagnosis of HIV-positive patients with a preserved CD4 count who present with peripheral neuropathy.

RESUMO

BACKGROUND: Spinal infections, including paraspinal and/or epidural abscesses and vertebral discitis and osteomyelitis, can have devastating consequences. The diagnostic imaging modality of choice has traditionally been magnetic resonance imaging (MRI) given the very high sensitivity and specificity, although the role of MRI in follow-up of spinal infections and how this relates to follow-up clinical status is poorly understood. We sought to understand the relationship between follow-up MRI and clinical status. METHODS: We conducted a retrospective review of adults with spinal infection to assess the relationship between follow-up MRI and clinical course. The degree of agreement between MRI and clinical follow-up was assessed using the Cohen kappa coefficient. A multinomial logistic regression model was applied to assess the impact of covariates in affecting the clinical outcome and MRI at follow-up independently. RESULTS: Ninety-eight patients met inclusion criteria during a 13-year period. We observed a lack of correlation between clinical follow-up status and MRI (κ = 0.065, P = 0.322). The McNemar-Bowker test for symmetry revealed that this disagreement was asymmetric (P < 0.001). Notably, clinical worsening was never associated with an improved MRI, and clinical improvement was overall not predictive of MRI result and vice versa. CONCLUSIONS: Routine follow-up MRI does not seem to correlate with clinical follow-up among patients with spinal infections. The use of MRI without new clinical indications in routine follow-up testing should be interpreted with caution.

RESUMO

OBJECTIVE: This article reviews the chest radiographic and CT findings in patients with presumed/laboratory-confirmed novel swine-origin influenza A (H1N1) virus (S-OIV) infection. MATERIALS AND METHODS: Of 222 patients with novel S-OIV (H1N1) infection seen from May 2009 to July 2009, 66 patients (30%) who underwent chest radiographs formed the study population. Group 1 patients (n = 14) required ICU admission and advanced mechanical ventilation, and group 2 (n = 52) did not. The initial radiographs were evaluated for the pattern (consolidation, ground-glass, nodules, and reticulation), distribution, and extent of abnormality. Chest CT scans (n = 15) were reviewed for the same findings and for pulmonary embolism (PE) when performed using IV contrast medium. RESULTS: Group 1 patients were predominantly male with a higher mean age (43.5 years versus 22.1 years in group 2; p < 0.001). The initial radiograph was abnormal in 28 of 66 (42%) subjects. The predominant radiographic finding was patchy consolidation (14/28; 50%) most commonly in the lower (20/28; 71%) and central lung zones (20/28; 71%). All group 1 patients had abnormal initial radiographs; extensive disease involving > or = 3 lung zones was seen in 93% (13/14) versus 9.6% (5/52) in group 2 (p < 0.001). No group 2 patients had > 20% overall lung involvement on initial radiographs compared with 93% of group 1 patients (13/14). PEs were seen on CT in 5/14 (36%) of group 1 patients. CONCLUSION: Chest radiographs are normal in more than half of patients with S-OIV (H1N1) and progress to bilateral extensive air-space disease in severely ill patients, who are at a high risk for PE.

RESUMO

On November 4, 2008, our state passed the Michigan Medical Marijuana Act (MMMA), which allows the medical use of marijuana for certain conditions and/or constellation of symptoms. This article will (1) review the current evidence that medical marijuana is useful for certain chronic conditions, particularly pain and wasting syndromes experienced by HIV-positive people; (2) discuss the adverse effects of marijuana; (3) summarize the new Michigan law and the challenges it poses for physicians, and (4) review the experience in California where medical marijuana has been legal since 1996.

RESUMO

OBJECTIVE: Clostridioides difficile infection (CDI) frequently causes colitis following antibiotic exposure and is a leading cause of gastrointestinal infectious mortality. Infection in the small bowel, C. difficile enteritis (CDE), was previously thought impossible, but case series have challenged this dogma. Clostridioides difficile enteritis prevalence, severity, and potential risk factors are unknown. METHODS: We retrospectively analyzed all total colectomy patients over a 20-year period at our institution. C. difficile enteritis was defined by clinical symptoms and positive C. difficile stool testing after colectomy. We compared CDE cases to controls using multivariable analysis to identify potential CDE risk factors. RESULTS: C. difficile enteritis occurred in 44 of 855 (5.1%) patients, a median of 130 days after colectomy. Compared to controls, CDE patients were similar in age, gender, and presence of immunosuppression. The majority (64%) had antibiotics <30 days prior to CDE. In multivariable analysis, CDE risk factors included perioperative acid suppression (hazard ratio [HR], 2.52; 95% confidence interval [CI], 1.26-5.04; P = .009), colectomy for inflammatory bowel disease (HR, 2.95; CI, 1.29-6.72; P = .010), colectomy for CDI (HR, 9.95; CI, 2.70-36.63; P ≤ .001), and ß-lactam use in the setting of enteral feeds (HR, 17.83; CI, 2.75-115.68; P = .003). C. difficile enteritis presented with severe disease half of the time, with 81.8% requiring hospitalization. CONCLUSIONS: C. difficile enteritis is a rare clinical entity that should be considered in postcolectomy patients presenting with CDI symptoms, even years after surgery. Like traditional CDI, likely CDE risk factors include acid suppression and inflammatory bowel disease. Prior antibiotic use in the setting of enteral feeds may amplify CDE risk. C. difficile enteritis often presents as severe disease and frequently requires hospitalization.

RESUMO

BACKGROUND: Due to their broad-spectrum activity and oral bioavailability, fluoroquinolone antibiotics are commonly prescribed to adults aged >60 years for many common community-acquired infections. The association between fluoroquinolone use and Achilles tendinitis is well established but sometimes missed in clinical practice. Older patients and patients with renal dysfunction are at particularly increased risk for this complication. CASE SUMMARY: We present a case of Achilles tendinitis in a 77-year-old patient with renal dysfunction and a urinary tract infection (UTI) treated with ciprofloxacin 250 mg PO QD. Tendinitis developed within several days of the start of treatment and improved within 2 days of treatment cessation, without the need for intervention. The likelihood of ciprofloxacin having caused this reaction was probable (Naranjo score, 7). Early diagnosis and treatment cessation might have prevented tendon rupture, and the tendinitis resolved completely with subsequent physical therapy. CONCLUSION: Based on this outcome in this patient with UTI, fluoroquinolones should be used with caution, particularly in patients with risk factors predisposing to tendinitis, including advanced age and renal dysfunction.

RESUMO

Non-AIDS-defining cancers have recently gained more attention, and it appears that several of these cancers may be more common the the HAART era. By most accounts in the literature, the overall risk of non-AIDS-defining cancer in HIV-infected persons is 2 to 3 times that in the general population. In this article, we review the literature on 5 of the most common non-AIDS-defining cancers (Hodgkin disease, anal cancer, hepatocellular carcinoma, oral cancer, and lung cancer) in the pre- and post-HAART periods. It remains unclear whether earlier initiation (CD4+ cell count above 350/microL) of antiretroviral therapy may be beneficial in preventing non-AIDS-defining cancer. Further large-scale, randomized, prospective studies on this question are warranted.

RESUMO

We describe 2 patients who had human immunodeficiency virus (HIV) infection and who first developed human papillomavirus (HPV)-related anal squamous cell carcinoma and later, oral squamous cell carcinoma. At the time each patient developed oral cancer, they were responding well to antiretroviral therapy with undetectable viral loads.

RESUMO

BACKGROUND: Some treatment-experienced patients with highly drug-resistant human immunodeficiency virus (HIV) infection have no option but to continue to receive an incompletely suppressive regimen (ISR). We performed a study to determine their long-term immunologic and virologic responses to ISR, to investigate risks for immunologic or virologic failure, and to examine for the occurrence of new drug-resistance mutations. METHODS: Antiretroviral treatment-experienced HIV-infected patients with a genotype sensitivity score < or = 1, an HIV load > 1000 copies/mL, and no available optimized regimen were included in the study. The proportion of patients treated with ISR who developed immunologic failure (defined as a 25% reduction in the CD4 cell count from the baseline level) and virologic failure (defined as a > or = 0.5-log10 increase in the HIV load from the baseline level) was determined. Cox proportional hazards analysis was used to investigate variables associated with immunologic or virologic failure. New drug-resistant mutations were calculated in 27 patients with sequential genotypes available. RESULTS: Forty-seven patients (median duration of prior antiretroviral therapy, 89 months; median CD4 cell count, 277 cells/mm3; and median HIV load, 19,728 copies/mL) had multiple HIV mutations (a median of 5 nucleoside reverse-transcriptase inhibitor mutations, 1 nonnucleoside reverse-transcriptase inhibitor mutation, and 6 protease inhibitor mutations; median genotype sensitivity score, 0) at baseline. By 48 months after ISR use, 43% had developed immunologic failure, and 22% had developed virologic failure. None of the studied variables (i.e., age, < 50 years; baseline HIV load, > 100,000 copies/mL; baseline CD4 cell count, < 200 cells/mm3; or inclusion of lamivudine in the treatment regimen) were associated with immunologic or virologic failure. New nucleoside reverse-transcriptase inhibitor mutations occurred in 63% of patients, and new primary protease inhibitor mutations occurred in 52.6% of protease inhibitor recipients. No deaths occurred. A total of 8.5% of patients experienced a new AIDS-defining event. CONCLUSIONS: Most patients with highly drug-resistant HIV infection who were treated with an ISR maintain durable immunologic and virologic responses. New drug-resistant mutations occur frequently.

RESUMO

Avian influenza or Influenza A (H5N1) is caused by a viral strain that occurs naturally in wild birds, but to which humans are immunologically naïve. If an influenza pandemic occurs, it is expected to have dire consequences, including millions of deaths, social disruption, and enormous economic consequences. The Department of Health and Human Resources plan, released in November 2005, clearly affirms the threat of a pandemic. Anticipating a disruption in many factions of society, every segment of the healthcare industry, including nursing homes, will be affected and will need to be self-sufficient. Disruption of vaccine distribution during the seasonal influenza vaccine shortage during the 2004/05 influenza season is but one example of erratic emergency planning. Nursing homes will have to make vital decisions and provide care to older adults who will not be on the initial priority list for vaccine. At the same time, nursing homes will face an anticipated shortage of antiviral medications and be expected to provide surge capacity for overwhelmed hospitals. This article provides an overview of current recommendations for pandemic preparedness and the potential effect of a pandemic on the nursing home industry. It highlights the need for collaborative planning and dialogue between nursing homes and various stakeholders already heavily invested in pandemic preparedness.

RESUMO

BACKGROUND: Few studies exist to guide the treatment approach to intra-abdominal abscesses in Crohn disease, which can include antimicrobials alone or in conjunction with percutaneous drainage or surgery. The primary aim of this study is to review outcomes from different treatment approaches to intra-abdominal abscess in Crohn disease. METHODS: Medical records were reviewed for patients admitted to the University of Michigan health care system with Crohn disease and intra-abdominal abscess over a 4-year period. Outcomes were compared among medical and interventional approaches. The χ2 test was used to test for statistical significance. RESULTS: Of the 33 patients included, 13 were in the medical group and 20 were in the interventional group. Abscess recurrence/nonresolution occurred in 31% of patients in the medical group and 25% of patients in the interventional group (P = .7). CONCLUSIONS: In this study, there was no significant difference in outcome between medical and interventional therapy for intra-abdominal abscess in Crohn disease.
