Is there a relation between vitamin D,interleukin-17, and bone mineral density in patients with inflammatory bowel disease?

IntroductionIn inflammatory bowel diseases (IBD), osteopenia and osteoporosis constitute a significant medical problem. Cytokines, especially IL-17, play an important role in the pathogenesis of IBD and osteoporosis. Vitamin D is a regulator of bone metabolism, and helps maintain immune system homeostasis.Material and methodsThe research sample consisted of 208 persons: 83 patients (age 35 ±11.99 years) with Crohn’s disease (CD); 86 patients (age 39.58 ±14.74 years) with ulcerative colitis (UC); and 39 persons (age 30.74 ±8.63 years) in the control group (CG). Clinical data on bone mineral density of the lumbar spine (L2-L4), bone mineral density of the femoral neck (FN), and body mass index (BMI) were collected. 25OHD and IL-17 serum concentrations were also measured.ResultsBody mass index (kg/m²) results: in CD, 21.51 ±3.68; in UC, 23.31 ±4.38; and in CG, 24.57 ±3.45 (p < 0.01). Densitometry results for L2–L4 T-score SD: in CD –0.83 ±1.45; in UC –0.47 ±1.15; in CG 0.09 ±0.70. Densitometry results for FN T-score SD: in CD –0.62 ±1.26; in UC –0.29±1.17; in CG 0.41 ±1.03 25OHD (ng/ml) serum concentrations: in CD, 21.33±12.50; in UC, 22.04±9.56; in CG, 21.56±9.11 (ns). IL-17 (pg/ml) serum concentrations: in CD, 8.55±10.99; in UC, 11.67±12.97; in CG, 5.16±9.11 (ns).ConclusionsInflammatory bowel diseases patients and persons from the CG did not differ in vitamin D or IL-17 levels. Patients with a mild course of the disease had a higher vitamin D concentration and bone mineral density. In UC, higher vitamin D concentrations were associated with lower IL-17 concentrations. The IBD patients with a severe course of the disease had a lower body mass than those in the CG and the patients with a mild course of the disease.     

Differences between older and younger adults with Borderline Personality Disorder on clinical presentation and impairment

Background

Borderline Personality Disorder (BPD) is well-known to be a clinically severe and impairing diagnosis. Research shows that BPD symptoms decrease in severity over time. However, a subset of patients with BPD continue to meet criteria for the disorder in older adulthood. Little is known about this subset. Perception of BPD as a young-person's diagnosis could lead to under recognition in older patients. As such, the objective of the present report is to provide the first direct comparison between older and younger adults with BPD on demographics, clinical presentation, and functional impairment.

Method

Over 3000 psychiatric outpatients were evaluated with semi-structured diagnostic interviews. Forty-six older adults (age 45–68) and 97 younger adults (age 18–25) met criteria for BPD.

Results

Both groups reported high levels of functional impairment and Axis I comorbidity. Older adults were more likely to endorse chronic emptiness, and less likely to endorse impulsivity, self-harm, and affective instability. Older adults also reported fewer substance use disorders, more lifetime hospitalizations and higher social impairment.

Conclusion

Older adults with BPD had a significantly different clinical presentation from younger adults with BPD, including differences in likelihood of endorsing specific BPD criteria, social impairment, and comorbid substance use. It is important to assess less prototypic features of BPD to avoid overlooking borderline personality features in this population.

Journal compilation © 2010 John Wiley & Sons A/S. Objectives: The negative impact of bipolar disorder on occupational functioning is well established. However, few studies have examined the persistence of unemployment, and no studies have examined the association between diagnostic comorbidity and sustained unemployment. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we described the amount of time unemployed in the five years before the evaluation in a large cohort of outpatients diagnosed with bipolar disorder, and determined the demographic and clinical correlates of sustained unemployment. Methods: A total of 206 patients diagnosed with DSM‐IV bipolar I or bipolar II disorder were interviewed with semi‐structured interviews assessing comorbid Axis I and Axis II disorders, demographic and clinical variables. The interview included an assessment of the amount of time missed from work due to psychiatric reasons during the past five years. Persistent unemployment was defined as missing up to two years or more from work. Results: Less than 20% of the patients reported not missing any time from work due to psychiatric reasons, and more than one‐third missed up to two years or more from work. Prolonged unemployment was associated with increased rates of current panic disorder and a lifetime history of alcohol abuse or dependence. Patients with prolonged unemployment were older and experienced more episodes of depression. Conclusions: Most patients presenting for the treatment of bipolar disorder have missed some time from work due to psychiatric reasons, and the persistence of employment problems is considerable. Comorbid psychiatric disorders are a potentially treatable risk factor for sustained unemployment. It is therefore of public health significance to determine if current treatments are effective in bipolar disorder patients with current panic disorder, and if not, to attempt to develop treatments that are effective.     

Microbiological effects in patients with leg ulcers and diabetic foot treated with Lucilia sericata larvae

Lucilia sericata bottle fly worms can be used to heal infected, chronic, or necrotic wounds, including those associated with ulceration and diabetic foot. The study aimed to evaluate changes in the microflora in patients treated with L sericata larvae due to leg ulcers and diabetic foot. One hundred twenty-nine patients diagnosed with lower limb ulceration and diabetic foot were enrolled in the study, of which 80 of them met the eligibility criteria for maggot debridement therapy (MDT). On the contrary, 49 unqualified patients were offered ozone therapy (22 with leg ulcers; 27 with diabetic foot). In each of these patients, a microbiological swab was performed before and after the start of therapy. The group of 80 patients was further divided into four equal groups in terms of the treated area (lower leg vs foot) and the number of larvae/cm² (5 vs 10). Twenty-three particular species of bacteria in the infected wound were studied microbiologically in terms of presence/absence within the wound environment before and after treatment of patients with diabetic foot and lower limb ulceration. It was noted that there was a more intensive bacterial accumulation in the feet of patients compared to legs; furthermore, this applies to almost all analysed species. Diabetes status is also a clinical factor that generates a lower chance of bacterial appearance in the wound environment. Densification of MDT larvae per wound area unit also reduced the chance of the presence of Corynebacterium species, Enterobacteriaceae, Pseudomonas aeruginosa, Staphylococcus aureus MSSA, and Streptococcus coagulase negativa; however, it increased the likelihood of occurrence for Proteus mirabilis and the Proteus species. A microbiological analysis in this non-reference study shows the efficacy of larval therapy for leg and foot ulcers. Rearrangement of the microflora within the wound has been reported as a result of the therapy.     

Durian (Durio zibethinus Murr.) cultivars as nutritional supplementation to rat's diets.

The properties of Mon Thong, Chani and Kan Yao durian (Durio zibethinus Murr.) cultivars were compared in vitro and in vivo studies in order to find the best one as a supplement to antiatherosclerotic diet. Total polyphenols (361.4+/-35.3 mgGAE/100g FW), flavonoids (93.9+/-8.9 mgCE/100g FW) and total antioxidant capacity determined by DPPH and beta-carotene-linoleic acid assays (261.3+/-25.3 microMTE/100g FW and 77.8+/-7.8% of inhibition) were maximal in Mon Thong in comparison with Chani and Kan Yao and showed a good correlation between these three variables (R(2)=0.9859). Five groups of rats were fed diets supplemented with cholesterol and different durian cultivars. Diets supplemented with Mon Thong and to a lesser degree with Chani and Kan Yao significantly hindered the rise in the plasma lipids (TC - 8.7%, 16.1% and 10.3% and (b) LDL-C - 20.1%, 31.3% and 23.5% for the Chol/Kan Yao, Chol/Mon Thong and Chol/Chani, respectively) and the decrease in plasma antioxidant activity (P<0.05). Nitrogen retention remained significantly higher in Chol/Mon Thong than in other diet groups. Diet supplemented with Mon Thong affected the composition of plasma fibrinogen in rats and showed more intensity in protein bands around 47 kDa. No lesions were found in the examined tissue of heart and brains. Mon Thong cultivar is preferable for the supplementation of the diet as positively influenced the lipid, antioxidant, protein and metabolic status. The durian fruit till now was not investigated extensively, therefore based on the results of this study durian cultivars can be used as a relatively new source of antioxidants.     

Role of dopamine D3 receptors in controlling the expression of cocaine sensitization in rats

It is established that dopamine (DA) is an important brain mediator of the behavioral (i.e. sensitizing) effects of cocaine in rodents. Among DA receptors, recent findings point to engagement of DA D3 receptors in cocaine addictive actions. In the present study, we attempted to determine the role of DA D3 receptors in the expression phase of sensitization to cocaine in rats, using the selective ligands 7-OH-PIPAT (an agonist) and nafadotride (an antagonist) of these receptors. Repeated administration (1-5 days) of cocaine (10 mg/kg, ip) to male Wistar rats significantly enhanced the locomotor activation induced by its challenge dose given after 5-day withdrawal (on day 10). 7-OH-PIPAT (1 mg/kg, but not 0.01-0.1 mg/kg, sc) administered together with a challenge dose of cocaine significantly decreased the response to cocaine in rats treated repeatedly with cocaine. On the other hand, the expression of cocaine sensitization was increased when that drug was combined with nafadotride (0.4 mg/kg, ip) on day 10. The results indicate a role of DA D3 receptors in controlling the expression of cocaine sensitization in rats, and may suggest an importance of DA D3 receptor agonists in the therapy of cocaine abuse.

Analysis of epileptic pregnant women delivering between 1992-1998 in obstetric departments of the University Medical School in Lublin

Pregnancy in woman with epilepsy arouses several serious medical problems and always belongs to the group of high obstetric risks. The aim of the present clinical study was the evaluation of the antiepileptic treatment efficiency during pregnancy, including risk factor, effects on pregnancy and delivery in epileptic patients. The study group consisted of 84 epileptic pregnant women which delivered between 1992-1998 in Obstetric Departments of University Medical School of Lublin. A randomised group 80 healthy pregnant women constituted the control group. The mean age of the analysed patients was 25 years. 51 epileptic patients were pregnant for the first time, 23 patients for the second time and 10 patients for the third time or more. The mean duration time of the disease was 8.6 years. In our study group: 45 (53.8%) patients experienced primary generalized tonic-clonic seizures and 39 (46.6%) patients experienced partial seizures. 26 patients were treated with monotherapy and the rest with polytherapy methods. The estimation of the seizure frequency during pregnancy in 52 (61.9%) patients did not change, in 13 (15.4%) patients increased. Among obstetric complications: urinary tract infections, hypertonia (EPH-gestosis) were observed. In 4 newborn congenital defects have been noted. Mothers of three of them were treated with Phenydantin (heart lesion, developmental anomaly of fingers). The fourth mother used Convulex (meningoarachnided hernia, hydrocephalus).
