Filter by:This is a prospective, randomized, open-label, evaluator-blinded, single center, proof of concept trial to explore possible beneficial effect of minocycline on acute ischemic stroke (AIS) undergoing endovascular treatment due to basilar artery occlusion (BAO). Minocycline has excellent safety profiles, have been previously demonstrated individually to reduce infarction in animal models of stroke, and have potentially mechanisms of antioxidant, anti-inflammatory, anti-apoptotic and protection of blood-brain barrier. However, it is not known whether minocycline can reduce futile recanalization of endovascular treatment, and improve the outcome of patients with AIS due to BAO. Eligible and willing subjects will be randomly assigned to the treatment group or the control group. The treatment group will receive 200 mg oral minocycline within three hours prior to successful reperfusion, followed by 100 mg every 12 hours times for a total of 5 days. Both groups will receive endovascular thrombectomy and standard medical. The treatment with minocycline will start as soon as possible after diagnosis of stroke. Measures of stroke severity and disability will be recorded at baseline and through the follow-up periods (90 days). The evaluator will be blind to the allocation of patients further minimizing the bias.
Cystoid macular edema (CME) is one of sight-threatening, immune-related ocular diseases. The efficacy of current treatments for CME (anti-VEGF, glucocorticoids and other agents) are limiting. Minocycline, acting as a broad-spectrum antibiotic, is among tetracycline family and recently, its immunomodulatory and anti-apoptosis function has been replied to several immune diseases and degenerative diseases. This study aims to explore the efficacy and safety of minocycline for CME.
Autoimmune uveitis is one kind of non-infectious, sight-threatening, relapsing and severe ocular disease. Approximately 20%-25% autoimmune uveitis patients suffer from the dilemma of blindness for the chronic and persistent inflammatory state in the eyes, which results in continuous destroy in the structure of the eyes and gradually leads to irreversible damage on visual function. However, it shows limiting efficacy of current treatment including glucocorticoids, immunosuppressant and biologics for chronic autoimmune uveitis. Minocycline has been regarded to have anti-apoptosis and immunemodulatory function for decades and it has been illustrated to be beneficial in several neuro-degenerative and neuro-inflammatory diseases. This trial aims to investigate the efficacy and safety of minocycline for chronic autoimmune uveitis with retinal degenerative changes.
The objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.
There is a subgroup of children with autism that appears to develop typically for a period of time, and then loses social or language skills, or regresses. A recent study by Vargas and co-workers at Johns Hopkins has demonstrated that this regressive type of autism is associated with chronic brain inflammation as shown by an abnormal production of inflammatory cytokines among other abnormalities. This present study will test the effectiveness of minocycline, an antibiotic with anti-inflammatory properties, in treating regressive autism. Although behavioral therapies have improved some symptoms of autism, there are no medical treatments for the disorder, and many children have ongoing behavioral difficulties. A medicine with anti-inflammatory properties may be beneficial for children with regressive autism. This will be an open-label trial, meaning all children in this study will receive minocycline. They will also receive vitamin B6 to reduce the possible chance of side effects of the minocycline. Children ages 3 to 12 with regressive autism may be eligible for this study. The children will take minocycline and vitamin B6 daily for 6 months. Prior to starting the medication and vitamin B6, children will receive a comprehensive diagnostic assessment for autism as well as a physical examination, medical history, and laboratory tests. Children will then receive ongoing assessments to monitor their behavior, communication, language skills, and medical issues at 2 weeks, and at 1, 2, 4, 6, and 12 months. Children who respond to the treatment will receive an additional 3 months of minocycline and vitamin B6.
Study Hypothesis: - Does a treatment with Minocycline of 2 x daily 2 x 50 mg effect the progression of clinical symptoms and diagnosis in patients with MSA? Background and Rationale: - The Parkinson-Syndrome which is characterised by the clinical triad akinesis, rigor and passive tremor, is caused by Parkinson's disease (PD) in about 70 % of the cases (Oertel et al., 2003). However, beside the Parkinson's disease there are several, to some extent rare, so-called atypical Parkinson's syndromes. The two most frequent of these atypical Parkinson-Syndromes are the - Multi-System-Atrophy (MSA) and the Progressive Supranuclear Palsy (PSP). Due to the often much varying courses and since they are not well known, these diseases are frequently diagnosed late or not diagnosed at all. Nevertheless, an early diagnosis is substantial for further treatment, since the prognosis and therapy of atypical Parkinson Syndromes differ essentially from those of PD. Whereas the neuronal death of cells in PD is restricted essentially to the Substantia nigra, a dominant destruction of neurons in brain stem, Cerebellum and Striatum additionally happens in cases of MSA and PSP. - Up to now no adequate treatment strategies are at disposal. Initially the giving of L-Dopa can lead to an improvement for < 10% of the patients only. - Minocycline is an antibiotic belonging to the group of the Tetracyclines. - Recently, it could be demonstrated that Minocycline has a neuroprotective impact besides the anti-inflammatory impact.
