Defensins couple dysbiosis to primary immunodeficiency in Crohn's disease

Antimicrobial peptides,including defensins,are essential effectors in host defence and in the maintenance of immune homeostasis.Clinical studies have linked the defective expression of both α-and β-defensin to the reduced killing of certain microorganisms by the intestinal mucosa of patients suffering from ileal and colonic Crohn's disease(CD),respectively.Only recently have the events leading to defective expression of defensins in CD been further elucidated,and are discussed herein.These events may account for CD-associated alterations in the microbiome and may subsequently precipitate the development of granulomatous inflammatory lesions in genetically-predisposed patients.We also address how these discoveries may pave the way for the development of a molecular medicine aimed at restoring gut barrier function in CD.

Proteomics analysis of IBS-D with spleen and kidney yang deficiency

Objective:To investigate the molecular mechanism underlying the development of diarrhea-predominant irritable bowel syndrome (IBS-D) with spleen and kidney yang deficiency (SKYD) using a proteomics approach.Methods:Male Sprague-Dawley rats (n =22) were divided into IBS-D (n =12) and normal control (n =10) groups.SKYD was then modeled in IBS-D rats by a combination of acetic acid enema,bondage,rectal dilation,tail stimulation,and Senna gavage.Colon tissue samples were subsequently collected and examined by Q Exactive mass spectrometry to identify differentially expressed proteins between the two groups.Results:The occurrence of SKYD/IBS-D was associated with ribosomal protein S23 (Rps23),protein phosphatase 2 catalytic subunit alpha (Pp2a),and growth factor receptor-bound protein 2 (Grb2),which are involved in the ribosome,neurotrophin signaling,and Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathways.Conclusion:These data suggest that SKYD/IBS-D pathophysiology likely involves inflammation,cell growth,apoptosis,stress granule formation,immune activation,loss of epithelial cell integrity,and visceral hypersensitivity.

Age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome with varied health status:a cross-sectional observational study

Objective:This study aimed to reveal the age-related changes in prevalence and symptom characteristics in kidney deficiency syndrome(KDS)with varied health status.Methods:This cross-sectional observational study was conducted in6 hospitals.Investigators queried participants aged 20e79 about their health,including symptoms if any,and completed questionnaires to collect participants responses.Prevalence,severity,and frequency of KDS and other relevant parameters were observed and recorded.Comparative analysis of countable variables,including prevalence,was performed by frequency analysis and c2 test and expressed as a composite ratio.Comparative analysis of quantitative scores of the severity and frequency of symptoms was performed by the rank-sum test.Regression analysis of the correlation of KDS with potential contributing factors was performed by non-conditional binary logistic stepwise regression of numerical variables.Results:Prevalence of KDS in healthy and unhealthy participants correlated with increasing age(P<0.05).In those with chronic disease,KDS prevalence was comparatively high,but the trend was not obvious.KDS prevalence in participants age 20e39 showed an increasing trend with deteriorating health(P<0.05).Compared to healthy individuals,KDS prevalence in subhealthy persons and those with chronic disease showed an increasing trend(P<0.05)in the 40e59 and 60e79 age groups,whereas there was no difference between subhealthy persons and those with chronic disease age 40e59 and 60e79.Symptom severity scores of KDS showed an increasing trend with increasing age and deteriorating health status(P<0.05).Higher symptom frequency scores were also positively correlated with increasing age(P<0.05),but health status deterioration was not significantly correlated(P>0.05).Age,health status,lower back pain,shin soreness or heel pain,tinnitus or deafness,hair loss or loose teeth,incomplete bladder emptying or incontinence,and sexual dysfunction or infertility were potential factors contributing to KDS(P<0.05),but age was the only independent variable for which OR>1.Moreover,the distribution of typical KDS-related symptoms showed dramatic regularities.Conclusion:Prevalence and symptom characteristics of KDS were found to increase consistently with increasing age and deteriorating health status.Kidney deficiency may be an important mechanism of aging in the subhealthy and chronic disease states.

Baseline survey of pregnant women's knowledge of treatment to prevent mother- to-child human immunodeficiency virus transmission in a resource limited setting

Despite continuing advances in scientific knowledge about treatments to prevent mother-to-child(MTCT)of the human immune deficiency virus(HIV),there is a paucity of data on pregnant women’s knowledge of treatments to prevent MTCT of HIV in Aba,South Eastern Nigeria.We investigated pregnant women’s knowledge of the availability of treatments to prevent MTCT of HIV in the low resourced setting of Aba town in South Eastern Nigeria.A descriptive study involving 100 consecutive and consenting patients at the antenatal clinic of Abia State University Teaching Hospital(ABSUTH),Aba,South Eastern Nigeria over the period 1st November, 2007 to 30th November,2007.Using a structured questionnaire,the respondents’sociodemographic data were obtained as well as their knowledge of the availability of treatments to prevent mother to child HIV transmission in pregnant women and self-reported data on their having ever tested for HIV.Knowledge regarding availability of treatment to prevent mother to child transmission of HIV was good as 95%of the respondents were aware that such treatment was available.Knowledge that treatment is available to help someone infected by HIV to live longer was also good as 96% of the respondents were aware of the availability of such treatment.Seventy one percent of the respondents had ever tested for HIV.The levels of knowledge regarding the availability of treatment to prevent mother to child HIV transmission and to help someone infected with HIV are good.Thus, utilization of anti-retroviral prophylaxis amongst HIV infected pregnant women in this community would be expected to be high if the drugs were available.This will reduce the impact of HIV,especially in children.

Seasonal climate effect on organ proportion and morbidity in 'Bi-zheng' rats with kidney deficiency syndrome

Objective:Using the traditional Chinese medicine theory of 'Bi-zheng' caused by kidney deficiency,combined with modern medical science and technology,this study assessed the relationships among organ weight,cytokines,pathological manifestations,and traditional Chinese medicine kidney deficiency syndrome in rats with rheumatoid arthritis.Methods:Sixty Sprague-Dawley rats were randomly divided into normal,collagen-induced arthritis (ClA) model,and kidney deficiency arthralgia model groups.Rats in the kidney deficiency arthritis group underwent removal of the testis or ovary and administration of an inflammatory agent.Rats in the control group solely received an inflammatory agent.Type Ⅱ collagen-induced arthritis was induced within 1 week of the winter solstice or summer solstice,in order to sample organs and observe the mental state,posture,fur color,activity level,excrement,body weight,and organ weight of the rats.Results:Compared with the normal and CIA model groups,the kidney deficiency arthralgia model group showed fast and acute onset,prominent symptoms,most obvious potential joint swelling,worst general state,and least amount of weight gain.Compared with the normal group,the proportion of thymus,spleen,and adrenal glands of model rats were larger in winter,with varying degrees of hyperplasia and hypertrophy;these differences were statistically significant (P <.05).In summer,model coefficients were greater than normal in the spleen,while the thymus and adrenal gland coefficients were significantly different between the normal and kidney deficiency arthralgia groups.In summer,the thymus in the kidney deficiency arthralgia group exhibited hypertrophy and hyperplasia,whereas the thymus in the control group did not;this difference was statistically significant (P =.015).Thymus and adrenal gland proportions exhibited seasonal differences in CIA model rats;these were statistically significant (P <.05),with high performance in winter and low performance in summer.The spleen proportion exhibited a trend of high performance in winter and low performance in summer in the kidney deficiency arthralgia model rats.Conclusion:Kidney deficiency is an internal condition linked with the occurrence of arthralgia,and seasonal factors exhibit an impact on the morbidity of arthritis in rats.

Systemic study on the safety of immuno-deficient nude mice treated by atmospheric plasma-activated water

Cold atmospheric-pressure plasma is a new technology, widely used in many fields of biomedicine,especially in cancer treatment. Cold plasma can selectively kill a variety of tumor cells, and its biological safety in clinical trials is also very important. In many cases, the patient’s immune level is relatively low, so we first studied the safety assessment of plasma treatment in an immunocompromised animal model. In this study, we examined the safety of immuno-deficient nude mice by oral lavage treatment of plasma-activated water, and studied the growth status, main organs and blood biochemical indexes. Acute toxicity test results showed that the maximum dose of plasma treatment for 15 min had no lethal effect and other acute toxicity. There were no significant changes in body weight and survival status of mice after 2 min and 4 min of plasma-activated water(PAW)treatment for 2 weeks. After treatment, the major organs, including heart, liver, spleen, lung and kidney, were not significantly changed in organ coefficient and tissue structure. Blood biochemical markers showed that blood neutrophils and mononuclear cells were slightly increased, and the others remained unchanged. Liver function, renal function, electrolytes, glucose metabolism and lipid metabolism were not affected by different doses of PAW treatment. The above results indicate that PAW treatment can be used to treat immuno-deficient nude mice without significant safety problems.

A Novel Approach for Iron Deficiency Anaemia with Liposomal Iron: Concept to Clinic

Iron deficiency anaemia is the most common nutritional deficiency disorder, contributing to 50 percent of all the anaemias in the world. Dietary changes alone are insufficient for the correction and management of iron deficiency anaemia. Hence, iron supplementation is necessary. Conventional oral iron therapy is limited in many patients because of dose dependent side effects, insufficient absorption, lack of compliance and limitation in various inflammatory conditions. Liposomal iron is a technologically designed, innovative form of iron which due to its differential delivery system ensures higher absorption and bioavailability, greater tolerability and least gastro-intestinal side effects unlike conventional oral iron preparations. This review provides a critical discussion and a comprehensive view based on the author’s review of the medical literature concerning the technology of liposomal iron preparation, mechanism of its absorption, its advantage over conventional iron preparations and clinical evidence on its usage in iron deficient states in pregnancy and certain inflammatory conditions.

Role of vitamin D in diabetes mellitus and chronic kidney disease

Approximately 30%-50% of people are recognized to have low levels of vitamin D,and insufficiency and deficiency of vitamin D are recognized as global health problems worldwide.Although the presence of hypovitamin D increases the risk of rickets and fractures,low vitamin D levels are also associated with hypertension,cancer,and cardiovascular disease.In addition,diabetes mellitus(DM) and chronic kidney disease(CKD) are also related to vitamin D levels.Vitamin D deficiency has been linked to onset and progression of DM.Although in patients with DM the relationship between vitamin D and insulin secretion,insulin resistance,and β-cell dysfunction are pointed out,evidence regarding vitamin D levels and DM is contradictory,and well controlled studies are needed.In addition,vitamin D influences the renin-angiotensin system,inflammation,and mineral bone disease,which may be associated with the cause and progression CKD.There is increasing evidence that vitamin D deficiency may be a risk factor for DM and CKD;however,it remains uncertain whether vitamin D deficiency also predisposes to death from DM and CKD.Although at this time,supplementation with vitamin D has not been shown to improve glycemic control or prevent incident DM,clinical trials with sufficient sample size,study periods,and optimal doses of vitamin D supplementation are still needed.This review focuses on the mechanism of vitamin D insufficiency and deficiency in DM or CKD,and discusses the current evidence regarding supplementation with vitamin D in patients with these diseases.
