Active clinical trials for "Mycobacterium Infections"

Background: - Tuberculosis (TB) is an infectious disease that affects numerous people worldwide. Researchers are interested in actively recruiting individuals with TB for research and treatment studies. Objectives: - To collect blood and other samples to study the natural history of tuberculosis. Eligibility: - Individuals 2 years of age and older who have either active or latent tuberculosis. Design: Latent TB patients: Participants will have a single study visit with a physical examination and medical history, and will provide blood samples for testing. Active TB patients: Participants will have an initial visit with a physical examination and medical history, and will provide blood samples for testing. Participants will also provide sputum samples if required, and may have an optional skin punch biopsy to collect a sample of skin tissue for study. Treatment for active TB will be provided as part of this protocol. Active TB participants may be asked to return for study visits every 1-2 months while receiving treatment....

Sources of NTM infection and modes of transmission among CF patients are poorly understood. Healthcare-associated transmission of NTM among CF patients has been suspected and is of growing concern for CF Centers. There is a need for a systematic evidence-based approach to investigating potential episodes of healthcare-associated transmission. Clusters of highly similar strains of NTM in CF patients cared for at the same CF Center may arise from healthcare sources including patient-to-patient transmission and/or acquisition from water sources within a healthcare setting. The primary objective of the study is to facilitate a standardized process by which CF Centers may perform data abstraction on patients identified with highly similar NTM isolates and determine if clustered NTM strains are related to strains isolated from healthcare setting water biofilm sources. HALT NTM is available to the entire CF Foundation Care Network, under a collaborative agreement, to initiate a standardized, independent, confidential, internal NTM outbreak investigation. Patients that are identified by whole genome sequencing as having highly similar NTM strains and receiving care in the same CF Care Center are eligible. The study's primary endpoint is to identify potential modes and sources of healthcare-associated acquisition of CF NTM, thereby revealing risk factors for NTM acquisition.

Comparison of rapid detection methods of mycobacterial pathogens, GenSeizer v.s. PCR reverse hybridization.

This study will examine the symptoms, course of disease and treatment of non-tuberculous mycobacterial (NTM) infections, as well as the genetics involved in these infections. Patients with NTM have recurrent lung infections and sometimes infections of the skin and other organs as well. They may also have curvature of the spine, barrel chest, and heart valve weakness. The study will compare the features of NTM with those of Job syndrome and cystic fibrosis, other diseases involving recurrent infections of the lungs and possibly other organs. Patients with diagnosed or suspected non-tuberculous mycobacterial infection, cystic fibrosis or Job syndrome may be eligible for this study. All participants will have a medical and family history, blood and urine tests, imaging studies that may include X-rays, computed tomography (CT) or magnetic resonance imaging (MRI) scans, and DNA and other genetic studies. In addition, all patients with Job syndrome and cystic fibrosis, and patients with NTM who have lung disease undergo the following procedures: Scoliosis survey X-rays of the spine to look for curvature or other abnormalities of the spinal column Echocardiography imaging test that uses sound waves to examine the heart chambers and valves Electrocardiogram measurement of the electrical activity of the heart Pulmonary function tests breathing tests to measure how much air the patient can move into and out of the lungs Body measurements measurements of height, weight, arm span, finger length, etc. Joint function assessment of joint mobility using different maneuvers to test flexibility of joints and ligaments Examination of physical features that might be associated with NTM, such as high arched palate of the mouth, flat feet, or certain skin features Dermatology (skin) examination for reactive skin conditions or other skin problems and possibly a skin biopsy (surgical removal of a small skin tissue sample for microscopic examination) Interview with genetics specialist These tests may require several days to complete. Patients with NTM will also be examined by a cystic fibrosis specialist and may have a sweat test. In addition, NTM patients will be asked to return to NIH every year for 5 years for follow-up tests, if medically indicated, including CT of the chest, scoliosis survey and examination by other specialists.

Based on the collected antibiotic concentration data and individual patient's clinical information, a pharmacokinetic analysis report that can be applied for dose adjustment of the individual patient is provided. The pharmacokinetic/pharmacodynamic index using the minimum inhibition concentration (MIC) of the antibiotic obtained from the patient's clinical isolate is also explored. Utilizing these, we intend to establish a population pharmacokinetic model of antibiotics prescribed in treating Tuberculosis and Nontuberculous mycobacteria (NTM). The developed population pharmacokinetic model can be applied for therapeutic drug monitoring (TDM) based on dose adjustment through the obtained pharmacokinetic parameters.

To evaluate the pharmacokinetics (PK) of SPR719, the active moiety, generated from the orally (po) administered SPR720 prodrug in a patient population with nontuberculous mycobacteria pulmonary disease (NTM-PD)

The purpose of this study is to determine the pharmacokinetics (how a drug is absorbed, distributed, and eliminated by the body) of moxifloxacin alone versus moxifloxacin given with rifapentine. Researchers believe that understanding how these tuberculosis drugs interact when given together may help to determine the best drug treatment plan for use in future studies. Volunteers will take moxifloxacin daily by mouth for the first part of the study and then moxifloxacin in combination with rifapentine during the second part of the study. Sixteen healthy men and women will be recruited from Johns Hopkins University School of Medicine to volunteer for this study. They will be required to stay in the inpatient unit twice, each time for 84 hours. Study procedures will include having a tube placed in a vein to draw several blood samples over time. Volunteers will participate in the study for a maximum of 48 days, including screening and follow-up visits.

This study proposed the comparison the overall survival, hematological toxicity, pain reduction score,PSA levels, tumor response, quality of life in two arms of HRPC patients from different parts of India.

A study to evaluate the efficacy of inhaled molgramostim administered open-label to adult cystic fibrosis (CF) subjects with chronic pulmonary nontuberculous mycobacterial (NTM) infection, with or without ongoing antimycobacterial guideline based combination therapy.

Pulmonary NTM infection is recognized as one of the most challenging infections to treat among people with cystic fibrosis (PwCF), notable for prolonged treatment courses and often poor response to therapy. Positive cultures for NTM occur in about 20% of children and adults with cystic fibrosis (CF). However, the source of NTM infection, modes of transmission, and exposure risks are poorly understood. It is thought that NTM is primarily acquired from environmental sites including soil and water as well as water supply systems to homes, hospitals, and clinics and from aerosols generated by flowing water from taps, showers, and fountains. Nonetheless, no direct molecular link has been established between environmental NTM and respiratory CF NTM. Healthcare-associated transmission of NTM among CF patients has been suspected and is of growing concern for CF Centers worldwide. Widespread global transmission of NTM, potentially via person-to-person transmission of fomites and aerosols has been reported. The parent HALT NTM study developed and published a standardized epidemiologic outbreak toolkit for investigation of healthcare-associated NTM outbreaks in CF Care Centers. We are now moving to a prospective investigation, with the long-term goal of real-time early identification and mitigation of potential NTM outbreak investigations coupled with healthcare environmental sampling and home of residence watershed analysis of PwCF identified as belonging to an NTM cluster and receiving care at a single CF Care Center.
