Gender differences in self-rated health,quality of life,quality of care,and metabolic control in patients with diabetes

Background: Because the projected increase in the number of diabetic patients is expected to strain the capabilities of health care providers worldwide, we are challenged to find ways of reducing the burden of diabetes. Maintaining and improving health-related quality of life (QoL) for diabetic patients may be viewed as public health goals.Objective: The aim of this cross-sectional study was to compare different aspects of health, QoL, and quality of care (QoC) between men and women with diabetes as a basis for planning and managing diabees care.Methods: All patients in 2 age groups (aged 20–30 years [younger age group] and aged 50–60 years [middle-aged group]) who were registered with the Department of Endocrinology, Metabolism, and Diabetes at Karolinska University Hospital, Stockholm, Sweden, in October 2004, were recruited for a survey. Questions were included about self-rated health (SRH), QoL, QoC, diabetes-related worries, occupational status, physical activity level, living arrangements, and educational background. Glycosylated hemoglobin (HbA_1c) values were obtained from medical records.Results: Of the 223 eligible patients (109 men, 114 women) in the younger age group, 49 men and 74 women responded to the questionnaire; of the 300 eligible patients (170 men, 130 women) in the middle-aged group, 120 men and 93 women responded. Middle-aged women rated their mental well-being and QoL as worse compared with men (P < 0.001 and P < 0.05, respectively). In both age groups, women reported more diabetes-related worries and less ability to cope (P < 0.05 for the younger age group and P < 0.001 for the middle-aged group for both variables), thus the differences were more marked for middleaged women. Although there were no gender differences in metabolic control, middle-aged women reported less satisfaction with diabetes care (P < 0.001). Higher HbA_1c was related to worse SRH in both men and women when analyzing the age groups together (P < 0.05). This association was most prominent in young women, in whom having more diabetes-related worries was also related to higher HbA_1c (P < 0.01).Conclusion: In this study, women with diabetes appeared to have worse QoL and mental well-being compared with men with diabetes. Therefore, identifying strategies to improve SRH and QoL among diabetic patients, especially among women, is of great importance.     

Gender differences in Parkinson's disease

Because estrogen has numerous effects on dopamine neurotransmission, many researchers are interested in its possible use to either slow the progression or reduce the risk of Parkinson's disease (PD). The incidence of PD is greater in men than in women. Gender differences in neurotoxicity have been observed, and basic research in experimental animals indicates that estrogen protects neurons from various forms of injury. However, the results of retrospective surveys of the neuroprotective effects of estrogen replacement in PD have been mixed, with some showing no effect on risk and others showing a reduction in risk. A mildly significant gender difference in disability and quality-of-life reporting has been noted, with women citing greater disability and reduced quality of life. Gender differences have been shown in response to treatment of PD, for example, in how levodopa is metabolized-women have greater levodopa bioavailability. In the Parkinson's Disease on Estrogen Therapy Replacement in the Menopause Years (POETRY) study, participants were found to have improved scores on the Unified Parkinson Disease Rating Scale. Based on the POETRY results, it is hypothesized that estrogen replacement therapy (ERT) may lead to improvement in PD symptoms and provide an opportunity to reduce the dosage of antiparkinsonian medication in women.     

Cytokines in inflammatory bowel disease

Over the past decade, much has been learned regarding the role of various cytokines in the pathogenesis of inflammatory bowel disease. Several cytokine 'knockout' models in mice have been shown to develop colitis, while alterations in the production of various cytokines has been documented in human Crohn's disease and ulcerative colitis. In recent years, attempts have been made to treat these diseases through modulation of cytokine production or action. This review focuses on the cytokines that have been implicated in the pathogenesis of inflammatory bowel disease. The evidence for and against a role for particular cytokines in intestinal inflammation is reviewed, as is the experimental and clinical data suggesting that cytokines are rational targets for the development of new therapies.     

Health related quality of life among patients with tuberculosis and HIV in Thailand

Introduction

Health utilities of tuberculosis (TB) patients may be diminished by side effects from medication, prolonged treatment duration, physical effects of the disease itself, and social stigma attached to the disease.

Methods

We collected health utility data from Thai patients who were on TB treatment or had been successfully treated for TB for the purpose of economic modeling. Structured questionnaire and EuroQol (EQ-5D) and EuroQol visual analog scale (EQ-VAS) instruments were used as data collection tools. We compared utility of patients with two co-morbidities calculated using multiplicative model (U_CAL) with the direct measures and fitted Tobit regression models to examine factors predictive of health utility and to assess difference in health utilities of patients in various medical conditions.

Results

Of 222 patients analyzed, 138 (62%) were male; median age at enrollment was 40 years (interquartile range [IQR], 35–47). Median monthly household income was 6,000 Baht (187 US$; IQR, 4,000–15,000 Baht [125–469 US$]). Concordance correlation coefficient between utilities measured using EQ-5D and EQ-VAS (U_EQ-5D and U_VAS, respectively) was 0.6. U_CAL for HIV-infected TB patients was statistically different from the measured U_EQ-5D (p-value<0.01) and U_VAS (p-value<0.01). In tobit regression analysis, factors independently predictive of U_EQ-5D included age and monthly household income. Patients aged ≥40 years old rated U_EQ-5D significantly lower than younger persons. Higher U_EQ-5D was significantly associated with higher monthly household income in a dose response fashion. The median U_EQ-5D was highest among patients who had been successfully treated for TB and lowest among multi-drug resistant TB (MDR-TB) patients who were on treatment.

Conclusions

U_CAL of patients with two co-morbidities overestimated the measured utilities, warranting further research of how best to estimate utilities of patients with such conditions. TB and MDR-TB treatments impacted on patients'' self perceived health status. This effect diminished after successful treatment.     

The biopsychosocial model of treatment the patients with inflammatory chronic bowel disease

We present the organised psychological group interventions for persons with inflammatory bowel disease (ulcerose colitis, Morbus Crohn). The actual bio-psychosocial model of health and illness is used to explain the situation of chronically ill patient as stressful life position and their ways of coping with such, health-related problems. Considering that numerous psychological factors can lead to insufficient illness adaptation and (non) adherence to treatment--and all those--to much more complications and higher use of therapies, we try to develop for group of those patients effective model of treatment. The group of 15 gastroenterological patients from treatment in UKC Maribor was included in the psycho-diagnostic procedure (semi-structural interview, The Freiburg's Personal Inventory, The Coping Inventory for Stressful Situations, Health-related Questionnaire of Quality of Life). The data that we had been gathered were significant to the C-type of coping, found in some other group of chronically ill patients, too. For such persons is typically their low emotions expressiveness, especially negative emotions (sadness, anger). In interpersonal contacts they usually show extreme social agreement and low level of assertiveness. So we formed our therapeutic model and its therapeutic aims to the course of being able to express the emotions, to reach higher personal autonomy, better assertively and self image--which at the end have all greater influence on the human's quality of life. After therapeutic model and aims of treatment has been formed, patients with inflammatory bowel disease were treated in cognitive-behavioural group, where also C. Roger's conditions for successful psychotherapy were taken in account and were the part of hole, integrative form of treatment.     

Oral health related quality of life in Slovenian patients with craniomandibular disorders

Sixty eight consecutive Slovenian patients with craniomandibular disorders (CMD) participated as the study group and another 400 adults from the regional population sample participated as the control group. The aim was to determine the impact of craniomandibular disorders to the self-perceived oral health related quality of life (OHRQoL) and to compare the OHRQoL with a control group. The mean Oral Health Impact Profile (OHIP) summary scores were computed for all patients with the same diagnosis and for the same subgroups of the axis I according to the RDC/TMD exam protocol. The mean OHIP subscores for the seven domains of the OHIP questionnaire were compared between the study and the control group. Significantly higher OHIP summary scores and all the OHIP subscores were obtained in the CMD patients in comparison with the control group (p<0.05). Furthermore, in the CMD group, patients with two related diagnoses had significantly higher impaired OHRQoL than patients with a single one. The results revealed: 1. The CMD subjects are highly associated with the reduced OHRQoL, 2. Higher number of diagnoses of the axis I according to the RDC/TMD results in the more impaired OHRQoL, 3. The higher age of the patients revealed the more impaired OHRQoL.     

Methylenetetrahydrofolate reductase C677T variant in Moroccan patients with inflammatory bowel disease

Background

The association of genetic polymorphisms related to metabolism of homocysteine and folate with inflammatory bowel disease has been evidenced. Several studies have identified genetic variants of MTHFR as significant susceptibility loci for Crohn's disease (CD) and ulcerative colitis (UC). The C677T genetic polymorphism in the MTHFR gene is found to be associated with a thermolabile variant enzyme that shows a reduced activity. Therefore, we investigated whether the C677T variant confers genetic susceptibility to CD or UC and evaluated the genotype–phenotype associations in the Moroccan population.

Methods

The present study included 96 inflammatory bowel disease patients (68 patients with CD and 28 with UC) and 182 healthy controls. DNA samples were genotyped for the MTHFR (C677T) mutation by the PCR-RFLP method. Statistical analyzes were performed using MedCalc software, Chi square test and Fisher test.

Results

The respective odds ratio for CD, UC and control group were, 1.55 (CI 95%: 0.53–4.53, P = 0.52); 0.50 (CI 95%: 0.06–4.15, P = 0.52) and 0.50 (CI 95%: 0.06–4.15, P = 0.52). Thus, no statistically significant association with the disease was observed in frequency of the TT variant in comparison to healthy controls. Stratification of IBD patients on the basis of CD or UC showed that individuals carrying at least one T allele are not protected against Crohn's disease. Furthermore, clinical features of the disease did not show any significant association.

Conclusion

In conclusion, the present study indicates that the genetic risk for IBD is not modulated by MTHFR C677T polymorphism in Moroccan population.     

Gender differences in coronary heart disease

Cardiovascular disease develops 7 to 10 years later in women than in men and is still the major cause of death in women. The risk of heart disease in women is often underestimated due to the misperception that females are ‘protected’ against cardiovascular disease. The under-recognition of heart disease and differences in clinical presentation in women lead to less aggressive treatment strategies and a lower representation of women in clinical trials. Furthermore, self-awareness in women and identification of their cardiovascular risk factors needs more attention, which should result in a better prevention of cardiovascular events. In this review we summarise the major issues that are important in the diagnosis and treatment of coronary heart disease in women. (Neth Heart J 2010;18:598–603.)     

Serological markers for inflammatory bowel disease in AIDS patients with evidence of microbial translocation

Background

Breakdown of the gut mucosal barrier during chronic HIV infection allows translocation of bacterial products such as lipopolysaccharides (LPS) from the gut into the circulation. Microbial translocation also occurs in inflammatory bowel disease (IBD). IBD serological markers are useful in the diagnosis of IBD and to differentiate between Crohn''s disease (CD) and ulcerative colitis (UC). Here, we evaluate detection of IBD serological markers in HIV-infected patients with advanced disease and their relationship to HIV disease markers.

Methods

IBD serological markers (ASCA, pANCA, anti-OmpC, and anti-CBir1) were measured by ELISA in plasma from AIDS patients (n = 26) with low CD4 counts (<300 cells/µl) and high plasma LPS levels, and results correlated with clinical data. For meta-analysis, relevant data were abstracted from 20 articles.

Results

IBD serological markers were detected in approximately 65% of AIDS patients with evidence of microbial translocation. An antibody pattern consistent with IBD was detected in 46%; of these, 75% had a CD-like pattern. Meta-analysis of data from 20 published studies on IBD serological markers in CD, UC, and non-IBD control subjects indicated that IBD serological markers are detected more frequently in AIDS patients than in non-IBD disease controls and healthy controls, but less frequently than in CD patients. There was no association between IBD serological markers and HIV disease markers (plasma viral load and CD4 counts) in the study cohort.

Conclusions

IBD serological markers may provide a non-invasive approach to monitor HIV-related inflammatory gut disease. Further studies to investigate their clinical significance in HIV-infected individuals are warranted.

Lipoxin biosynthesis in inflammatory bowel disease

BACKGROUND AND AIMS: Lipoxins are anti-inflammatory lipid mediators that are produced in gut mucosa, which serve to limit and resolve persistent inflammation. The purpose of this study was to evaluate colonic lipoxin biosynthesis in patients with ulcerative colitis (UC) to establish a possible biochemical basis for persistent inflammation in UC. METHODS: Colonic mucosa from patients with UC or organ donors (controls) was placed into tissue culture for 90 min. The conditioned media was assayed (ELISA) for lipoxin A4 (LXA) and the biologically active isomer 15-epi-LXA4 (aspirin triggered lipoxin, ATL). Mucosal tissue 15-lipoxygenase protein was determined by Western blot. RESULTS: Patient colonic mucosa produced significantly lower (12-fold) amounts of LXA, relative to organ donors. This occurred irregardless of patient steroid treatment. However, patient tissue responded to in vitro aspirin by synthesizing biologically active ATL. For the first time, human colonic mucosa was found to synthesize 15-lipoxygenase-2, an epithelial-derived isoenzyme used for lipoxin synthesis. These levels were significantly lower in UC patients compared to the control tissue. Finally, mice chronically treated with a putative selective 15-lipoxygenase inhibitor (PD 146176) experienced significantly worse intestinal function during experimental colitis, relative to untreated mice. CONCLUSION: Colonic mucosa from UC patients demonstrated defective lipoxin biosynthesis, which may contribute to the inability of these patients to resolve persistent colonic inflammation.     

Pregnancy and inflammatory bowel disease.

Conclusions about the relationship between the pathophysiology and treatment of inflammatory bowel disease and the physiology and management of pregnancy are based on the results of several large physician surveys and retrospective chart reviews. Patients with active disease fare worse than those with inactive disease. There is little evidence that pregnancy affects the course of inflammatory bowel disease or that inactive inflammatory bowel disease affects the course of pregnancy. Judicious medical therapy is effective in controlling inflammatory bowel disease during pregnancy. Sulfasalazine or steroid therapy should not be withdrawn in a patient who needs it to achieve or maintain a quiescent state of inflammatory bowel disease during the course of pregnancy. Immunosuppressive therapy should be avoided. Aggressive medical therapy with total parenteral nutrition in a team approach with a gastroenterologist, surgeon, and perinatologist usually avoids the need for surgical intervention during pregnancy with a good fetal outcome in a patient whose disease is active. Contraception against pregnancy need only be considered in those patients whose disease is so severe that operative therapy is imminent.     

Juvenile onset inflammatory bowel disease: height and body mass index in adult life.

OBJECTIVE--To establish the frequency of permanent growth failure in juvenile onset inflammatory bowel disease. DESIGN--Measurement of height and weight in a geographically based cohort at a mean of 14 (range 5.2-29.5) years after diagnosis. Comparison with data from surveys of British adults in 1980 and 1987. SETTING--NHS hospitals throughout Scotland. SUBJECTS--105 Children admitted to hospital during 1968-83 who fulfilled diagnostic criteria for Crohn''s disease or ulcerative colitis and lived in specified regions. 87 were aged over 18 and living in Britain at follow up. MAIN OUTCOME MEASURES--Height, weight, body mass index, and sexual maturity. RESULTS--All patients were sexually mature. 67 of the 70 patients examined were of normal height, and three women with Crohn''s disease were abnormally short. Weight and body mass index were normal in all patients with ulcerative colitis. Patients with Crohn''s disease had significantly lower weight than those with ulcerative colitis (men 66.8 (9.5) kg v 78.4 (13.8) kg, P = 0.04; women 51.5 (8.2) kg v 63.0 (12.1) kg, P < 0.02) irrespective of disease activity. Body mass index was also significantly lower than the normal distribution (P < 0.01). Growth retardation was not mentioned as a problem for any of the 17 patients interviewed only by telephone. CONCLUSIONS--Despite growth retardation in the teenage years most young people with inflammatory bowel disease will eventually achieve normal height. Reasons for lower weight in patients with Crohn''s disease remain to be established.     

Differential protein expression profile in the intestinal epithelium from patients with inflammatory bowel disease

The loss of intestinal epithelial cell (IEC) function is a critical component in the initiation and perpetuation of chronic intestinal inflammation in the genetically susceptible host. We applied proteome analysis (PA) to characterize changes in the protein expression profile of primary IEC from patients with Crohn's disease (CD) and ulcerative colitis (UC). Surgical specimens from 18 patients with active CD (N = 6), UC (N = 6), and colonic cancer (N = 6) were used to purify primary IEC from ileal and colonic tissues. Changes in protein expression were identified using 2D-gel electrophoreses (2D SDS-PAGE) and peptide mass fingerprinting via MALDI-TOF mass spectrometry (MS) as well as Western blot analysis. PA of primary IEC from inflamed ileal tissue of CD patients and colonic tissue of UC patients identified 21 protein spots with at least 2-fold changes in steady-state expression levels compared to the noninflamed tissue of control patients. Statistical significance was achieved for 9 proteins including the Rho-GDP dissociation inhibitor alpha that was up-regulated in CD and UC patients. Additionally, 40 proteins with significantly altered expression levels were identified in IEC from inflamed compared to noninflamed tissue regions of single UC (N = 2) patients. The most significant change was detected for programmed cell death protein 8 (7.4-fold increase) and annexin 2A (7.7-fold increase). PA in primary IEC from IBD patients revealed significant expression changes of proteins that are associated with signal transduction, stress response as well as energy metabolism. The induction of Rho GDI alpha expression may be associated with the destruction of IEC homeostasis under condition of chronic intestinal inflammation.     

益生菌在炎症性肠病中的治疗作用

炎症性肠病(inflammatory bowel disease,IBD)包括溃疡性结肠炎(ulcerative colitis,UC)和克罗恩病(Crohn’s disease,CD)。随着对肠道微生物群在IBD发病机制中作用的认识不断深入,近年来益生菌广泛应用于IBD治疗。大量临床试验结果表明,益生菌治疗IBD的疗效主要体现在对UC和贮袋炎的治疗,对CD的疗效不明确。益生菌治疗IBD可能通过促进肠道微生物群平衡、改善肠道屏障功能、调节肠道黏膜免疫及营养物质代谢等途径。     

Gender differences in inflammatory proteins and pathways in seasonal allergic rhinitis

In model organisms, thousands of genes differ in expression between females and males. It is not known if differences on a similar scale are found in humans nor how this relates to disease. However, in allergic disease gender differences in the levels of both inflammatory cells and proteins have been shown. In this study, we found lower nasal fluid allergen-specific IgE in women than men with seasonal allergic rhinitis (SAR). This led to genome-wide analyses of gene expression in allergen-challenged CD4⁺ cells from patients with SAR before and after treatment with cortisone. Before treatment, 975 genes differed in expression between women and men: 337 were higher in women. After treatment only 428 genes and one pathway differed in expression. The genes that differed in expression between women and men were over-represented in 10 pathways. Five of the pathways regulated chemotaxis. All five were less active in women. One of the pathways was induced by the eosinophilic chemokine CCL4. Analysis of nasal fluid CCL4 protein confirmed lower levels in women with seasonal allergic rhinitis, before and during the pollen season. By contrast, nasal fluid CCL3 levels did not differ between the genders. In summary, this study shows gender differences in specific inflammatory pathways and proteins in patients with seasonal allergic rhinitis. Further studies are warranted to examine if such differences have diagnostic and therapeutic implications in allergic diseases.     

The insulin-like growth factor system and markers of inflammation in adult patients with inflammatory bowel disease

BACKGROUND AND OBJECTIVES: Catabolism and growth impairment are well-known complications of inflammatory bowel disease (IBD). Recent studies have demonstrated significant changes in the IGF system in IBD patients. The aim of the present study was to investigate correlations between the IGF system and markers of inflammation in IBD. METHODS: A cross-sectional study comprising 99 IBD patients (Crohn's disease (CD, n = 50) and ulcerative colitis (UC, n = 49)). Correlations between markers of inflammation and IGF-I, IGF-II and IGFBP-3 were examined in CD and UC patients in remission and relapse. The patients were clinically scored using Crohn's Disease Activity Index (CDAI) for CD patients and Activity Index (AI) for UC patients. RESULTS: In the UC group we found correlations between IGF-I and CRP (r(s) = Spearman's rho) (r(s) = -0.40, p < 0.01) and albumin (r(s) = 0.46, p < 0.001), IGFBP-3 and albumin (r(s) = 0.36, p < 0.01) and AI score (r(s) = -0.31, p < 0.05). IGF-II correlated with CRP (r(s) = -0.42, p < 0.01), IL-6 (r(s) = -0.65, p < 0.001), albumin (r(s) = 0.41, p < 0.01), AI score (r(s) = -0.30, p < 0.05) and orosomucoid (r(s) = -0.47, p < 0.001). In the CD group we found correlations between IGF-I and CRP (r(s) = -0.40, p < 0.05), and albumin (r(s) = -0.46, p < 0.01), IGFBP-3 and albumin (r = 0.36, p < 0.01). IGF-II correlated with IL-6 (r(s) = -0.65, p < 0.001), albumin (r(s) = 0.41, p < 0.01), CDAI score (r(s) = -0.30, p < 0.05) and orosomucoid (r(s) = -0.47, p < 0.001). CONCLUSIONS: IGF-I, IGF-II and IGFBP-3 are correlated to albumin and IGF-I and IGF-II are correlated to CRP in IBD patients. Further, IGF-II is correlated to IL-6 in IBD patients. This may suggest a correlation between inflammation and the IGF system with involvement in muscle and bone catabolism in IBD.
