Communicating with patients with inflammatory bowel disease

Ulcerative colitis and Crohn's disease, the two main forms of inflammatory bowel disease (IBD), are chronic illnesses that affect hundreds of thousands of Americans. Patients with IBD suffer chronically from diarrhea, abdominal pain, gastrointestinal bleeding, malabsorption, and weight loss requiring continuous medical and surgical attention. Despite recent advances in therapy, IBD follows a course of exacerbations and remissions with approximately 25-50% of patients relapsing annually. Hence, these diseases are readily encountered in primary care and gastroenterology clinics. Though medical and surgical treatment options have improved significantly, little has been written about the psychosocial aspects of IBD. Currently, there is a paucity of data concerning effective communication methods enabling physicians to develop stronger rapport with patients suffering from IBD, the care of whom requires a multidisciplinary approach involving primary care physicians, gastroenterologists, and colorectal surgeons. Because IBD has a high morbidity, it is worthwhile to further investigate those social factors that will improve patients' quality of life. In this paper, we summarize some of the common problems that emerge when taking care of patients with IBD and provide initial guidelines based on the world literature regarding the management and education of patients with IBD. Both primary care physicians and specialists (gastroenterologists, colorectal surgeons) need to be aware of the questions and concerns of IBD patients and to be capable of dispensing the information in a clear and concise manner. Using the case scenario format, we review the most common aspects of communication for health care professionals taking care of IBD patients and suggest ways to establish and maintain long-term doctor-patient relationships. The two most significant interventions that dramatically improve quality of life and patient-physician relationships are proper patient education and appropriate treatment of concurrent depression and anxiety. We hope that our review will form a framework by which different members of the medical team learn their roles in the complex management decisions affecting IBD patients.     

Pulmonary artery aneurysms in Behçet's disease: contribution of imaging in 5 cases

Pulmonary involvement in Beh?et's disease is an uncommon condition (12%). Thromboembolism of the superior vena cava and/or other mediastinal veins, aneurysms of the aorta and pulmonary arteries are the main vascular manifestations in addition to pulmonary infarct and intrathoracic hemorrhage. Despite their scarcity, respiratory symptoms may be life-threatening. The aim of this study was to assess the contribution of thoracic imaging for one of the most serious aspects of the disease: pulmonary artery aneurysm. We report five patients with pulmonary artery aneurysms (mean age: 39.5 years). Hemoptysia revealed Beh?et's disease in three. Initially explored by conventional radiography, computed tomography and angiography, pulmonary artery aneurysms are currently investigated well with helicoidal computed tomography, digital angiography, magnetic resonance imaging (MRI) and angio-MRI. These imaging techniques provide helpful information for the diagnosis of Beh?et's disease.     

Evaluation of Estrogen,Progesterone, and GCDFP-15 Expression in Uterine Leiomyomas

Approximately, one fourth of women have leiomyomas. Leiomyomas are benign tumors that originated from smooth muscle cells. Estrogen is claimed to relate as a cause but exact mechanism has not fully understood. In this study, 95 leiomyoma cases that have been diagnosed by our department in years between 2010 and 2012 were examined. Age ranges of patients, sizes, locations, and numbers of leiomyomas were identified. Immunohistochemically ER (estrogen), PR (progesterone), and Gross cystic disease fluid protein-15 stains were performed to the paraffin blocks and their percentages of staining were noted. Statistically, submucosal and intramural locations were significantly related to ER and PR (p < 0,001). There were significant relationship between ER and PR in 30–50 years age group (p < 0,001). There were significant relationship between ER, PR and locations (p < 0,001), numbers (p < 0,001), sizes of leiomyomas (below 5 cm; p < 0,001), (between 5 and 10 cm; p = 0,037), larger than 10 cm; p = 0,002). Consequently, relationship between leiomyoma and ER, PR were revealed in this study. Also, relationship between leiomyoma locations and patient ages were identified statistically. There was no immunoreactivity with GCDFP-15 in leiomyomas.     

Healthy ranges of serum alanine aminotransferase levels in Iranian blood donors

AIM: The healthy ranges for serum alanine aminotransferase (ALT) levels are less well studied. The aim of this study was to define the upper limit of normal (ULN) for serum ALT levels, and to assess factors associated with serum ALT activity in apparently healthy blood donors. METHODS: A total of 1,939 blood donors were included. ALT measurements were performed for all cases using the same laboratory method. Healthy ranges for ALT levels were computed from the population at the lowest risk for liver disease. Univariate and multivariate analyses were performed to evaluate associations between clinical factors and ALT levels. RESULTS: Serum ALT activity was independently associated with body mass index (BMI) and male gender, but not associated with age. Association of ALT with BMI was more prominent in males than in females. Upper limit of normal for non-overweight women (BMI of less than 25) was 34 U/L, and for non-overweight men was 40 U/L. CONCLUSION: Serum ALT is strongly associated with sex and BMI. The normal range of ALT should be defined for male and female separately.

Treatment of external genital warts in men with imiquimod 2% in cream. A placebo-controlled, double-blind study

OBJECTIVE: The purpose of this double-blind, placebo-controlled study was to evaluate the safety, clinical efficacy and tolerability of imiquimod (2%) in cream to cure external genital warts in males. METHODS: Preselected male patients (n=60) ranging between 18 and 50 years of age (mean 24.2) harbouring 558 lesions (mean 9.3) with clinical, histopathological and polymerase chain reaction (PCR) confirmed diagnosis of human papilloma virus (HPV) infection were randomized to two parallel groups. Each patient was allocated a precoded 25g tube, and instructions on how to apply the trial medication to their lesions at home once daily for three consecutive days per week (max. 12 application in 4 weeks). To evaluate the safety, clinical efficacy and tolerance, patients were exa-mined on a weekly basis. Cure was defined as the total elimination of treated warts with PCR, and Southern blot hybridization confirmed negative HPV DNA. RESULTS: By the end of the treatment, 40% (24/60) patients and 49.8% (278/558) warts were cured. Breaking the code revealed that imiquimod cream had cured 70% (21/30) patients and 86.8% of warts, while placebo healed three subjects and 28 warts (P=0.0001). Eleven patients (18.3%), predominantly in the imiquimod cream group, experienced mild to moderate, non-objective, drug-related side effects with no dropouts. The study was followed up for 18 months from the first day of the treatment, and among the 26 cured patients, one in the imiquimod cream group and two in the placebo had a relapse after 14 months. CONCLUSION: The study demonstrated that 2% imiquimod in cream with mild non-objective side effects is safe, tolerable and significantly more effective than placebo in curing external genital warts in males.     

Comparison of effects on low-density lipoprotein cholesterol and high-density lipoprotein cholesterol with rosuvastatin versus atorvastatin in patients with type IIa or IIb hypercholesterolemia.

This randomized, double-blind, placebo-controlled trial was conducted in 52 centers in North America to compare the effects of the new, highly effective statin, rosuvastatin, with atorvastatin and placebo in hypercholesterolemic patients. After a 6-week dietary run-in, 516 patients with low-density lipoprotein (LDL) cholesterol > or =4.14 mmol/L (160 mg/dl) and < 6.47 mmol/L (250 mg/dl) and triglycerides < or =4.52 mmol/L (400 mg/dl) were randomized to 12 weeks of once-daily placebo (n = 132), rosuvastatin 5 mg (n = 128), rosuvastatin 10 mg (n = 129), or atorvastatin 10 mg (n = 127). The primary efficacy end point was percent change in LDL cholesterol. Secondary efficacy variables were achievement of National Cholesterol Education Program (NCEP) Adult Treatment Panel II (ATP II), ATP III, and European Atherosclerosis Society LDL cholesterol goals and percent change from baseline in high-density lipoprotein (HDL) cholesterol, total cholesterol, triglycerides, non-HDL cholesterol, apolipoprotein B, and apolipoprotein A-I. Rosuvastatin 5 and 10 mg compared with atorvastatin 10 mg were associated with greater LDL cholesterol reductions (-40% and -43% vs 35%; p <0.01 and p <0.001, respectively) and HDL cholesterol increases (13% and 12% vs 8%, p <0.01 and p <0.05, respectively). Total cholesterol and apolipoprotein B reductions and apolipoprotein A-I increases were also greater with rosuvastatin; triglyceride reductions were similar. Rosuvastatin 5 and 10 mg were associated with improved achievement in ATP II (84% in both rosuvastatin groups vs 73%) and ATP III (84% and 82% vs 72%) LDL cholesterol goals, and rosuvastatin 10 mg was more effective than atorvastatin in achieving European Atherosclerosis Society LDL cholesterol goals. Both treatments were well tolerated.     

Comparative efficacy and safety of aliskiren, an oral direct renin inhibitor, and ramipril in hypertension: a 6-month, randomized, double-blind trial

OBJECTIVES: This double-blind study compared long-term efficacy, safety and tolerability of the oral direct renin inhibitor aliskiren and the angiotensin-converting enzyme inhibitor ramipril alone and combined with hydrochlorothiazide in patients with hypertension. METHODS: After a 2-4-week placebo run-in, 842 patients [mean sitting diastolic blood pressure (msDBP) 95-109 mmHg] were randomized to aliskiren 150 mg (n = 420) or ramipril 5 mg (n = 422). Dose titration (to aliskiren 300 mg/ramipril 10 mg) and subsequent hydrochlorothiazide addition (12.5 mg, titrated to 25 mg if required) were permitted at weeks 6, 12, 18 and 21 for inadequate blood pressure control. Patients completing the 26-week active-controlled treatment period were re-randomized to their existing regimen or placebo for a 4-week double-blind withdrawal phase. RESULTS: Six hundred and eighty-seven patients (81.6%) completed the active treatment period. At week 26, aliskiren-based therapy produced greater mean reductions in mean sitting systolic blood pressure (17.9 versus 15.2 mmHg, P = 0.0036) and msDBP (13.2 versus 12.0 mmHg, P = 0.025), and higher rates of systolic blood pressure control (< 140 mmHg; 72.5 versus 64.1%, P = 0.0075) compared with ramipril-based therapy. During withdrawal, blood pressure increased more rapidly after stopping ramipril than aliskiren-based therapy; median blood pressure reached 140/90 mmHg after 1 and 4 weeks, respectively. Blood pressure reductions were maintained with continued active treatment. Aliskiren therapy was well tolerated. Overall adverse event rates were similar with aliskiren (61.3%) and ramipril (60.4%); cough was more frequent with ramipril (9.5%) than aliskiren (4.1%). CONCLUSIONS: Aliskiren-based therapy was well tolerated and produced sustained blood pressure reductions in patients with hypertension over 6 months, greater than those with ramipril-based therapy.     

Long-term outcome in diabetic heart failure patients treated with cardiac resynchronization therapy

BACKGROUND: Diabetes mellitus is an independent risk factor for increased morbidity and mortality in heart failure (HF) patients. AIMS: To compare functional and structural improvement, as well as long-term outcome, between diabetic and non-diabetic HF patients treated with cardiac resynchronization therapy (CRT). METHODS: We compared response to CRT in 141 diabetic and 214 non-diabetic consecutive patients. Major events were; death from any cause, urgent heart transplantation and implantation of a left ventricular (LV) assist device. Frequencies of hospitalisation and defibrillator (CRT-D) discharges were also analyzed. RESULTS: CRT was able to significantly improve functional capacity, ventricular geometry and neurohumoral imbalance in both diabetic and non-diabetic patients over a median follow-up time of 34 months. Overall event-free survival was similar in diabetic and non-diabetic patients (HR 1.23, p=0.363), as was survival free from CRT-D interventions (HR 1.72; p=0.115) and hospitalisations (HR 1.12; p=0.500). On multivariable analysis, NYHA class IV (p=0.002), low LV ejection fraction (p=0.002), absence of beta-blocker therapy (p<0.001), impaired renal function (p=0.003), presence of an epicardial lead (p=0.025), but not diabetes (p=0.821) were associated with a poor outcome after CRT. CONCLUSIONS: Diabetic HF patients treated with CRT had a very favourable functional and survival outcome, which was comparable to non-diabetic patients.
