NCT00000896 ↗ | A Study to Compare the Effectiveness of a Four Drug Anti-HIV Regimen Given Alone or in Combination With GM-CSF or IL-12 to HIV-Positive Patients | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | N/A | 1969-12-31 | The purpose of this study is to examine how the level of HIV is reduced in the blood when anti-HIV therapy is initiated. This study will also evaluate whether adding GM-CSF or IL-12 to the anti-HIV drug regimen will increase the rate that HIV is reduced. The anti-HIV drugs used in this study will include lamivudine (3TC), zidovudine (ZDV), indinavir (IDV), nevirapine (NVP), and stavudine (d4T). All have been used successfully to treat HIV. GM-CSF has been used to treat certain blood disorders; it will be used as an experimental drug in this study. IL-12 (interleukin-12) is a protein found naturally in the body that is thought to boost the immune system. Although GM-CSF and IL-12 have no direct effect against HIV, these drugs may improve the ability of the immune system to fight the virus. |
NCT00031070 ↗ | Increasing HAART-Induced Immune Restoration With Cyclosporine | Completed | National Institute of Allergy and Infectious Diseases (NIAID) | Phase 2 | 1969-12-31 | The purpose of this study is to see if cyclosporine, taken when a patient begins highly active antiretroviral therapy (HAART), increases the number of CD4 T-cells (blood cells that fight infection) in a patient's blood. This study also will explore the safety of briefly giving cyclosporine to patients starting HAART. |
NCT02422264 ↗ | Immunogenicity and Safety Study of Infanrix Hexa in Healthy Infants Born to Mothers Vaccinated With Boostrix™ During Pregnancy or Immediately Post-delivery | Completed | GlaxoSmithKline | Phase 4 | 2016-01-22 | The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' Infanrix hexa, given in the primary vaccination schedule to infants born to pregnant women who participated in study 116945 [DTPA (BOOSTRIX)-047]. This study will help us evaluate if the presence of transplacentally transferred maternal antibodies interfere with the immune response to primary vaccination with Infanrix hexa and a co-administered pneumococcal conjugate vaccine given as a part of this study in infants. |
NCT02542462 ↗ | Potential Mechanisms for Intussusception After Rotavirus Vaccine-Pilot Study | Completed | Centers for Disease Control and Prevention | Phase 4 | 2015-11-01 | This is a prospective randomized clinical trial that aims to evaluate the potential effects of the first dose of rotavirus vaccines on gastrointestinal motility and anatomy and blood and stool cytokine responses. It will also assess the association between these outcomes and the pattern of the shedding of vaccine strain rotavirus in the stool. Infants will be randomized to one of four arms: monovalent rotavirus vaccine (Rotarix®, RV1) alone, RV1 with other recommended vaccines, pentavalent rotavirus vaccine (RotaTeq®, RV5) alone, or RV5 with other recommended vaccines. Data derived from the pilot study will be used to assess the feasibility of conducting a larger scale study. |
NCT02542462 ↗ | Potential Mechanisms for Intussusception After Rotavirus Vaccine-Pilot Study | Completed | Children's Hospital Medical Center, Cincinnati | Phase 4 | 2015-11-01 | This is a prospective randomized clinical trial that aims to evaluate the potential effects of the first dose of rotavirus vaccines on gastrointestinal motility and anatomy and blood and stool cytokine responses. It will also assess the association between these outcomes and the pattern of the shedding of vaccine strain rotavirus in the stool.

In this clinical study we confirm that combination of isotretinoin and All trans retinoic acid can be used in the treatment of SARS-COV-2 better than vaccine according to the findings of previous studies and researches. Retenoic acid can induce neutralizing antibodies in case of corona virus (COVID-19) by restoring inhebited and exhausted T cells via inhebiting both CD13 and Angiotensin-converting enzyme-2 (ACE2). CD13 amyloid receptor which abundantly overexpressed on cell surface of lymphocyte, Dentritic cell, Macrophage, granulocytes and monocytes and is ubiquitous in respiratory tract epithelial cells, smooth muscle cells, fibroblasts, epithelial cells in the kidneys and small intestine, activated endothelial cells, and platelets In addition inhibing of Angiotensin-converting enzyme-2 (ACE2) , Angiotensin T1 protein and Angiotensin II-mediated intracellular calcium release pathway which is responsible for COVID-19 cell fusion and entry.ACE2-expressing cells are prone to SARS-CoV-2 infection as ACE2 receptor facilitates cellular viral entry and replication. A study demonestrated that patients with hypertension and diabetes mellitus may be at higher risk of SARS-CoV-2 infection, as these patients are often treated with ACE inhibitors (ACEIs) or angiotensin II type-I receptor blockers (ARBs), which have been previously suggested to increase ACE2 expression.Butisotretinoin was found to be the strongest down-regulator of ACE 2 receptors.and this will give hope for diabetic patients or patients with hypertension infected with COVID-19.Therefore we suggest that Retinoic Acid will help in inhabiting factors which may enhance antibody dependent enhancement (ADE), A phenomenon caused by covid-19 which expected to lead to failure of vaccination specially in case of corona virus (covid-19) as a hyper mutatated COVID-19 antigens can lead to (ADE) phenomenon in which IgG antibodies facilitate viral entry and fusion with infected cell through uptake of the virus-IgG complex via the Fc receptors and later viral fusion with antigen presenting cells like Dentric cells, macrophages and B cells via FcR , through the neonatal FcR instead of antibodies induced viral agglutination and this is known as antibody dependent enhancement (ADE)(2) ADE can hamper vaccine development, as a vaccine may cause the production of antibodies which, via ADE, worsen the disease the vaccine is designed to protect against. ADE in COVID-19 infection can be caused by high mutation rate of the gene that encodes spike (S) protein. In this clinical study we suggest that Hyper mutated spike protein ,lymphopenia, and impaired dentreic cells all these factors can help in and lead to delayed antibodies response and appearing after a period of covid -19 symptoms onset and this may be responsible for antibody dependent enhancement (ADE) Keywords: COVID 2019 , Retinoic acid, Lymphopenia ,T Cells, Dentric cells , ADE, Vaccine |
