The Johns Hopkins Transplant Infectious Diseases Prospective Cohort Study
TransplantationThe Transplant Infectious Diseases Prospective Cohort Study facilitates the prospective identification and collection of data of infectious disease complications in order to determine the epidemiology, risk factors, and outcomes of patients who receive solid organ or stem cell or plastic surgery transplants at Johns Hopkins and other transplant centers. It is essential for the care and treatment of this population to employ a mechanism for investigators to centralize these datasets, using standardized definitions of infectious complications. This protocol outlines the procedures to be utilized in order to prospectively follow the diagnosis and treatment of infectious complications in transplant patients.
Catheter Biofilm Microbiome in Infected Neonatal Catheters.
Catheter-associated Bloodstream Infections (CLABSI)Percutaneously Inserted Central Catheters (PICCs) are special tubes that are inserted into blood vessels of premature babies (neonates) to give them nutrition and medications. Sometimes these tubes get infected and they need to be removed. Also, the babies need to be given medications to treat these infections (antibiotics). PICC infections in neonates are a serious problem and we need to find new ways of detecting infections early so that we can treat them promptly to avoid complications. The purpose of this study is to understand what causes tube infections in neonates and to develop a test to detect tube infections early to avoid complications.
Widespread vs. Selective Screening for Hepatitis B Infection Prior to Chemotherapy
CancerHepatitis B3 moreThis trial studies hepatitis B screening strategies of new cancer patients scheduled to undergo chemotherapy. Patients with cancer and hepatitis B virus infection are at risk of reactivation of infection after chemotherapy. Hepatitis B virus infection reactivation can be prevented by starting antivirals before chemotherapy in patients who are hepatitis B virus infection positive. Hepatitis B screening may help doctors prevent the reactivation of hepatitis B virus infection after chemotherapy.
Gonorrhea and Chlamydia HIV-infected Men Who Have Sex With Men
HIV InfectionChlamydia1 moreThis study will estimate the rates of asymptomatic Chlamydia and/or Gonorrhea in the oropharynx, rectum and urethra (urine) of HIV infected men who have sex with men at a specialty care center and compare it to the rates in Douglas County, using nucleic acid amplification tests.

Using a Infrared Thermometer to the Early Detection of Catheter Related Infections
InfectionThis is a pilot study which aims to show the temperatures measured on body surface with an infrared thermometer on inpatients who need a central venous catheter (CVC) for medical care. Because the local temperature could be altered, at least during local infectious processes, seems to be reasonable to think that this approach could be helpful to its early diagnosis.
Assessment of CMV-specific ELISPOT Assay for Predicting CMV Co-infection in Patients With Pneumocystitis...
Non-HIV Patients With Pneumocystis Jiroveci PneumoniaPCP (Pneumocystis jiroveci pneumonia) is one of the important opportunistic infections in immunocompromised patients including HIV-infected patients, transplant recipients, and immunosuppressant users. About one third of non-HIV patients with PCP have the evidence of co-infection with CMV. In this difficult clinical situation, physicians have difficulty to decide on whether anti-CMV treament will help patients with any evidence of CMV co-infection. However, there is no objective test to differentiate true co-infection of CMV from innocent bystander of CMV in those with PCP. The investigators thus evaluate the usefulness of CMV-specific ELISPOT assay in patients with PCP to differentiate true co-infection of CMV from inocent bystander of CMV. This findings may guide physicians to decide anti-CMV treatment in patients with PCP and CMV co-infection.
