Filter by:Primary objective: - To estimate the degree of agreement in diagnosis of cytologic samples from mediastinal lymph nodes obtained by Endobronchial Ultrasound (EBUS)-guided Fine Needle Capillary Sampling (FNC) versus Fine Needle Aspiration (FNA). Secondary objective: - To compare the quality of cytologic samples from mediastinal lymph nodes obtained by EBUS-guided FNC versus FNA. The quality of the samples will be assessed initially by MDACC on-site cytology technicians, and then corroborated by physicians in the department of cytology. This assessment will be performed utilizing the Mair's score 3. The score consists of a 0-10 scale: 1-2= poor; 3-6=good; 7-10=superior.
This study will test whether valproic acid (Depakote[Registered Trademark]) can shrink enlarged lymph glands and spleen in patients with autoimmune lymphoproliferative syndrome (ALPS). Depakote has been used for more than 30 years for treating various medical disorders in adults and children, including migraine headaches, seizures and psychiatric disorders. In animal studies, it was effective in shrinking both lymph nodes and spleen in animals with conditions similar to ALPS. People with ALPS who are between 2 and 70 years of age and who have had an enlarged spleen or lymph glands for at least 1 year may be eligible for this study. Participants take Depakote as a tablet or liquid or sprinkled on food twice a day for 16 weeks. The drug dose is increased slowly over the first 3 to 4 weeks until the maximum tolerated dose is reached. Blood tests are done at 2, 4, 6, 8 and 10 weeks after starting the drug and 1 week after the drug is stopped to check for treatment side effects. Valproic acid blood levels will be checked during drug escalation, half way through therapy, and just before the end of treatment. A physical examination and CT scan (or ultrasound of the abdomen for patients who cannot undergo CT) are done before starting treatment and at the end of the 16-week treatment period to evaluate the response to treatment. Patients who tolerate the treatment well and show shrinkage of the lymph glands or spleen may be offered extended treatment for up to 1 year in consultation with their primary physician. During the extended treatment period, blood tests are done at home every 6 to 8 weeks to monitor for drug side effects. Follow up evaluation visits are scheduled at the NIH Clinical Center every 3 months during the extended treatment period and 3, 6, and 12 months after treatment has ended.
To evaluate the short-term effects of administering zidovudine ( AZT ) at the same time with increasing doses of aldesleukin ( interleukin-2; IL-2 ) in patients with persistent generalized lymphadenopathy syndrome ( PGL ). The effects to be studied include safety or toxicity, how quickly the drugs are used in the body, effects on the immune system, effects on HIV, concentrations in body fluids, and how quickly the drugs are cleared by the kidneys. The trial will establish the maximum tolerated dose ( MTD ) and will be a pilot study to determine the dose that has the greatest effect in the immune system. AZT has been shown to be effective in HIV-related disease. IL-2 has been shown to increase immune responses and correct immune problems caused by HIV in the test tube. IL-2 has also been effective in treating Kaposi's sarcoma in a number of patients. Because of the clinical activities of these two drugs and because their toxicities and mechanisms of action do not overlap, it may be beneficial to combine the two drugs with their antiviral and immune stimulatory effects.
