Active clinical trials for "Infections"

The aim of this study is to see if multiplex strip PCR will detect the pathogen that causing eye infection from the corneal scraping samples with higher sensitivity and specificity than the current gold standard.

This proposal will investigate the wound condition between different drainage methods of the stoma closure wound. Anastomotic leakage is a major complication after colorectal surgery. The protective stoma will decrease the anastomosis leakage rate and severity1. Stoma closure is often performed after the condition of the previous protecting site improved. Wound infection is not a rare complication after stoma closure, with a reported infectious rate from 3% to 43%. Wound infection will result in wound dehiscence, incisional herniation, ileus and the length of hospital stay. Lots of the stoma wound closure technique have been developed, including subcutaneous antibiotic material implantation, wound irrigation with iodine, closure wound with a drain tube, secondary closure, delayed primary closure and pursestring closure. But there still is in a debate about the best skin closure test. In Division of Colorectal Surgery Shuang Ho Hospital, two current stoma wound closure methods were subcutaneous Jackson-Pratt drainage and cutaneous Penrose drainage insertion. In the project, clinical outcomes of these two drainage methods will be compared. The subcutaneous. Jackson-Pratt drainage is used to create negative pressure in subcutaneous closure wound. The negative pressure will extract actively the tissue debris and fluid, avoiding the seroma and pus accumulation. The cutaneous Penrose drainage is used to create delayed skin healing, and the tissue debris and fluid will drainage passive by capillary phenomenon. Two groups will be distributed randomly. The demographic characters like age, gender, BMI, nutritional status, under chemotherapy, diabetes and past medication history will be reviewed. Perioperative clinical data like the method of the anastomosis, operation time, postoperative hospital day, surgical site infection, prolonged ileus, anastomosis leakage, and incisional hernia will be collected. From this study, these two stoma wound closure methods will be evaluated and analyze the risk factors of complication for the stoma wound closure.

The aim of this cohort is to identify environmental, lifestyle and genetic factors that modify the human intestinal microbiota development during the first years of life, and to identify early microbiota features that associate to child health and well-being with focus on the development of allergic diseases and overweight.

estimate the percentage of fungal infection in the pathogenesis of diabetic foot osteomyelitis and assess the outcome of patients with fungal diabetic foot osteomyelitis

The patients who accept the quadruple eradication program of the helicobacter pylori and success to eradicate helicobacter pylori will be followed-up to observe the situation of re-infection of helicobacter pylori.

All chronic hepatitis B (CHB) patients were diagnosed and treated in the liver disease department of the Hepatology Center of Beijing Ditan Hospital affiliated to Capital Medical University and those who received antiviral therapy (interferon and nucleoside analogues) reached HBsAg<100 IU/ml. The enrolled subjects were divided into the following six observation cohorts: 1) CHB patients in the immunological control period, without any clinical treatment intervention; 2) After interferon therapy, HBsAg<100 IU/ml, continued interferon therapy; 3) After interferon therapy, HBsAg<100 IU/ml, stopped interferon treatment; 4) After interferon therapy, HBsAg<100 IU/ml, sequential nucleoside analog treatment; 5) After nucleoside analogue treatment, HBsAg<100 IU/ml, sequential interferon treatment; 6) After treated with nucleoside analogues, HBsAg<100 IU/ml, continuing the nucleoside analog treatment. The follow-up observation period was 96 weeks under non-planned intervention. During the observation period, HBV indicators and biochemical indicators, serum AFP and liver imaging (liver ultrasound) were examined regularly. The main evaluation index was the incidence of HBsAg disappearance during the observation period. Secondary evaluation indicators: the rate of HBV DNA turning positive, the rate of HBeAg turning positive and hepatitis incidence. To observe the inactive carrier status of low HBsAg content and the incidence of HBsAg disappearance, clinical outcomes and influencing factors in patients with CHB under different antiviral interventions.

Chlamydia trachomatis is the most common cause of sexually transmitted bacterial infection in Sweden, an infection that is notifiable according to the Communicable Diseases Act and the Communicable Diseases Ordinance. Women account for 57 % of all cases detected since 1993. Recently published studies describe a high proportion of positive rectal chlamydia tests in women and in half of the cases there is no history of anal sex. In almost 20 % of cases, chlamydia has only been found rectally. Samples in these studies were self-collected and although the sensitivity of modern NAATs (Nucleic Acid Amplification Tests) is very high, there is even high risk of contamination of the sample due to the short anatomical distance between the vagina and the anus. Furthermore the vaginal sample has been taken prior to the rectal sample in the largest study from the Netherlands, something that further increases the risk of contamination of the rectal sample. There are experimental animal models which support the theory that chlamydia can be transferred along the gastrointestinal tract! This is a possible explanation for the occurrence of rectal chlamydia in women who have not had anal intercourse, but it is necessary to minimize the risk of contamination. The study will take part in three STD-clinics (2 counties) where two clinics are in the county of Östergötland (Norrköping and Linköping with totally 300 000 inhabitants) and one in the county of Jönköping (120 000 inhabitants). The risk of contamination of the rectal samples is minimized as the rectal sample is taken first and with the use of a pediatric proctoscope (a proctoscope that is designed to examine children) which is first inserted in the anus to allow sample collection from the rectal mucosa above the pectinate line, while avoiding contact of the collecting swab with the perineal skin. Then vaginal speculum examination is performed and samples are taken from endocervix and vagina for C.trachomatis N.gonorrhoeae and M.genitalium tests. Extra samples from the anus and the vagina will be collected and immediately frozen to minus 80 degrees to allow further testing with vPCR (viability Polymerase Chain Reaction). Positive chlamydia samples will be further analyzed with a high resolution method (Multi Locus Sequence Typing, or MLST and if necessary Multi-Locus Variable number tandem repeat Analysis or MLVA) to make the discrimination of various chlamydia types possible.

To obtain the characteristics of adverse reactions/incidents, analyze the influencing factors and calculate the incidence of adverse reactions/incidents monitored by Pudilan Xiaoyan Oral Liquid in key specialties in the real world, so as to provide a basis for clinical safe and rational drug use.

In recent years, the incidence of Inflammatory Bowel Disease (IBD) has been increasing in China, which poses great challenges and burdens to the medical community due to its unknown etiology, recurrence and incurability. Co-infection is one of the important causes in IBD development. IBD accompanied with Clostridium Difficile Infection (CDI) can significantly decrease the treatment efficiency, leading to increased surgical rate, increased mortality, prolonged hospital stay, and increased hospital costs. Recently, several Chinese clinical guidelines about IBD or CDI have been published, but these guidelines are mainly based on the foreign studies. Compared with the developed countries, the lack of multi-center, large-scale and multi-test clinical trials and cohort studies caused limited understanding for IBD-CDI in China. Therefore, it is of great importance to carry out the multi-center clinical trials and analysis on IBD-CDI to improve the diagnostic and therapeutic efficiency in IBD-CDI patients Objective: To evaluate the prevalence rate of IBD-CDI in Chinese adults in China based on the multi-center clinical trials.. To analyze the related risk factors of IBD-CDI in China based on the multi-center clinical trials. To analyze the intestinal flora of IBD-CDI patients via high-throughput sequencing.

The purpose of this study is to prospectively evaluate the value of Optical coherence tomography angiography (OCT-A) for the of detection of suspected retinal complications With Sofosbuvir (Sovaldi) in Patients With Hepatitis C Virus Infection
