Clinical Trials Search.org is a site dedicated to listing clinical research studies in human subjects. Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy Clinical research trials and Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy healthcare trials occur in a lot of of places throughout the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the potency of new drugs. The intent of the studies / undertakings is to figure out certain human medical questions. Clinical trials are a popular means for mDs, government agencies, and private sector corporations to locate remedies for all kinds of circumstances, including Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy. Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy Clinical Trials and other clinical trials allow volunteers to obtain health treatment alternatives before they are available to the masses. Many times the participants undergo treatment for free, and sometimes they are paid for their time. Occasionally there is a cost for a Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy clinical trial. Participants typically obtain the most effective healthcare available for their Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy condition. Dangers are a reality, nonetheless, and can include extra or frequent mD trips, medical hazards (potentially life-endangering), and/or the treatment being uneffective. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Aerosols in the Treatment of Pneumocystis Pneumonia: A Pilot Study Quantitating the Deposition of Aerosolized Pentamidine as Delivered in ACTG 040 and Comparing Its Toxicity With Parenteral Pentamidine Therapy
For Condition: Pneumonia, Pneumocystis carinii,HIV Infections
Status: Completed
Sponsor(s): National Institute of Allergy and Infectious Diseases (NIAID) ,
Synopsis: To compare the use of pentamidine aerosol (inhaled mist) with the standard intravenous method of administration in patients with AIDS related Pneumocystis carinii pneumonia (PCP), to measure the amount of pentamidine aerosol that actually reaches the lung, and to see if close clinical observation is safer and as effective as drug therapy in the prevention of PCP recurrences. To compare the efficiency of 2 nebulizers - the Respirgard II nebulizer and the Cadema Aerotech II nebulizer. Aerosolized pentamidine was as effective as intravenous pentamidine in treating PCP in animals. More of the pentamidine reached the lungs and less was found in the liver and kidney after pentamidine was given by aerosol than after an intravenous injection. This suggests that the toxicity of pentamidine may be less if given by aerosol than if given by the intravenous route.
Details: Aerosolized pentamidine was as effective as intravenous pentamidine in treating PCP in animals. More of the pentamidine reached the lungs and less was found in the liver and kidney after pentamidine was given by aerosol than after an intravenous injection. This suggests that the toxicity of pentamidine may be less if given by aerosol than if given by the intravenous route. Patients will inhale one dose of radiolabeled aerosol containing pentamidine, and an image of the lung will be taken immediately and then 24 hours later to determine the amount of pentamidine reaching the various areas of the lung. Patients will then undergo a bronchoalveolar lavage (BAL) in order to recover the PCP organism from the lung and to corroborate the diagnosis of PCP. If PCP organisms are detected, patients will be randomly assigned to aerosolized or intravenous pentamidine and treated for 21 days. Patients taking pentamidine by aerosol will repeat the radiolabeled aerosol study on day 9. The BAL will be repeated at the end of therapy for all patients. If patients do not improve within 9 days, they will be switched to another therapy. After completion of therapy, patients will be given the option of prophylactic therapy, i.e., doses of medication to prevent reinfection, for PCP. All patients will be carefully assessed every 4 weeks for 6 months whether they begin prophylactic therapy or not. Zidovudine (AZT) may not be taken during the 21-day trial because of the increased risk of side effects, but it can be resumed when PCP therapy is completed.
Eligibility:
Study Type: Interventional, Treatment, Parallel Assignment

Genders: Both
Protocol Entry Criteria: Inclusion Criteria Prior Medication: Allowed: - Prophylaxis for Pneumocystis carinii pneumonia (PCP); zidovudine. Unequivocal diagnosis of Pneumocystis carinii pneumonia (PCP) established by morphological confirmation of three or more typical Pneumocystis carinii organisms in bronchoalveolar lavage fluid, obtained immediately following the initial inhalation of radiolabeled aerosol. - Resting (A-a) DO2 < 30 torr on room air or resting (A-a) DO2 = or < 55 torr on room air with a serious intolerance to trimethoprim / sulfamethoxazole (TMP / SMX), defined as one or more of the following: - Platelets < 50000 platelets/mm3 or absolute neutrophil count (polys plus bands) = or < 500 cells/mm3 on at least two occasions = or > 12 hours apart. - Blistering rash, mucosal involvement, generalized maculopapular eruption, or intolerable pruritus. - Transaminase > 5 x ULN or = or > 300 IU if baseline is abnormal. - Daily temperature = or > 103 degrees F beginning after the 5th day of treatment and persisting for at least 3 days and not responsive to antipyretic therapy, with no other discernible cause. - Any other severe or life-threatening adverse reaction to TMP / SMX that, in the investigator's opinion, makes continued or recurrent treatment with TMP / SMX inadvisable (approved on a case-by-case basis by the NIAID clinical monitor).
