A randomised double-blind placebo-controlled trial of minocycline and/or Omega-3 fatty acids added to treatment as usual for At Risk Mental States (NAYAB): study protocol
Background
The At Risk Mental State (ARMS) describes individuals at high risk of developing schizophrenia or psychosis. The use of antipsychotics in this population is not supported because most individuals with ARMS are unlikely to develop psychosis. Anti-inflammatory treatments and polyunsaturated fatty acids (PUFAs) may have some beneficial effects in the treatment of ARMS. There have been no controlled clinical trials that have investigated the use of minocycline for ARMS and no trials involving PUFAs in combination with other proposed treatments. There is a need to find effective, tolerable and inexpensive interventions for ARMS that are available both in high, low and middle-income countries.
Methods
A six-month intervention study of minocycline and/or Omega-3 fatty acids added to treatment as usual (TAU) in patients with ARMS will be conducted in Pakistan using a randomised, placebo-controlled, double-blind factorial design. 320 consenting patients with capacity will be recruited from community, general practitioner clinics and psychiatric units. Allowing for a 25% dropout rate, we will recruit 59 completing participants to each study arm, and 236 will complete in total. We will determine whether the addition of minocycline and/or Omega-3 fatty acids to TAU attenuates rate of transition from ARMS to first-episode psychosis and improves symptoms and/or level of functioning in ARMS. We will also investigate whether any candidate risk factors such as negative symptoms, influence treatment response in the ARMS group. The primary efficacy end-point is conversion to psychotic disorder at 12 months post study entry. Analysis will be by intention-to-treat, using analysis-of variance, chi-squared tests and adjusted odds ratios to assess between-group differences. Cox regression analyses will be used to analyse potential between-group differences in time-to-onset of psychosis.
Discussion
The outcomes of this trial will provide evidence of the potential benefits of minocycline and PUFAs in the treatment of ARMS. Both minocycline and PUFAs are inexpensive are readily available in low/middle-income countries such as Pakistan, and if evidenced, may prove to be safe and effective for treating ARMS
Guidance on noncorticosteroid systemic immunomodulatory therapy in noninfectious uveitis: fundamentals of care for uveitis (focus) initiative
Topic: An international, expert-led consensus initiative to develop systematic, evidence-based recommendations for the treatment of noninfectious uveitis in the era of biologics.
Clinical Relevance: The availability of biologic agents for the treatment of human eye disease has altered practice patterns for the management of noninfectious uveitis. Current guidelines are insufficient to assure optimal use of noncorticosteroid systemic immunomodulatory agents.
Methods: An international expert steering committee comprising 9 uveitis specialists (including both ophthalmologists and rheumatologists) identified clinical questions and, together with 6 bibliographic fellows trained in uveitis, conducted a Preferred Reporting Items for Systematic Reviews and Meta-Analyses protocol systematic reviewof the literature (English language studies from January 1996 through June 2016; Medline [OVID], the Central Cochrane library, EMBASE,CINAHL,SCOPUS,BIOSIS, andWeb of Science). Publications included randomized controlled trials, prospective and retrospective studies with sufficient follow-up, case series with 15 cases or more, peer-reviewed articles, and hand-searched conference abstracts from key conferences. The proposed statements were circulated
among 130 international uveitis experts for review.Atotal of 44 globally representativegroupmembersmet in late 2016 to refine these guidelines using a modified Delphi technique and assigned Oxford levels of evidence.
Results: In total, 10 questions were addressed resulting in 21 evidence-based guidance statements covering the following topics: when to start noncorticosteroid immunomodulatory therapy, including both biologic and nonbiologic agents; what data to collect before treatment; when to modify or withdraw treatment; how to select agents based on individual efficacy and safety profiles; and evidence in specific uveitic conditions. Shared decision-making, communication among providers and safety monitoring also were addressed as part of the recommendations. Pharmacoeconomic considerations were not addressed.
Conclusions: Consensus guidelines were developed based on published literature, expert opinion, and practical experience to bridge the gap between clinical needs and medical evidence to support the treatment of patients with noninfectious uveitis with noncorticosteroid immunomodulatory agents
Inflammatory Arthritis, Sacroiliitis, and Morphea: Evidence of a Systemic Inflammatory Disease
Morphea is a skin disease characterized by local skin inflammation and fibrosis. Extracutaneous manifestations have been described with this disease including inflammatory arthritis. We describe a case of morphea who developed inflammatory polyarthritis and sacroiliitis coincident with new skin lesions
Unilateral Heliotrope Rash in Juvenile Dermatomyositis: An Unusual Presentation of an Underlying Serious Disease
Background. Heliotrope rash is one of the characteristic skin manifestations of juvenile dermatomyositis. It is a reddish-purple rash on the upper eyelids that is usually bilateral. Case Presentation. We report a boy who presented with unilateral heliotrope rash, Gottron’s papules, and muscle weakness. Muscle biopsy was consistent with inflammatory myositis. Patient was started on prednisolone and methotrexate with an excellent response in both the skin and muscles. Conclusion. Unilateral heliotrope rash can occur in patients with juvenile dermatomyositis. Being a paraneoplastic condition caution should be taken not to miss any underlying malignancy
Synthesis of Novel Triazoles, Tetrazine, Thiadiazoles and Their Biological Activities
An expedient synthesis of novel triazoles, tetrazine and thiadiazoles, using conveniently accessible and commercially available starting materials has been achieved. The synthesized compounds were characterized by spectroscopic and elemental analyses, and screened for their antibacterial activities against four different strains, namely E. coli, P. aeruginosa, S. aureus and B. megaterium. In particular, the compounds 5, 24 and 26h exhibited excellent antibacterial activities compared to the reference antibiotic. To get further insight about their behavior, these compounds were tested for their antioxidant activities via SOD-like activity, DPPH free radical scavenging activity, ABST and NO, which showed promising results. Furthermore, these compounds effectively promoted the cleavage of genomic DNA as well, in the absence of any external additives
Synthesis and Biological Evaluation of Bisthiazoles and Polythiazoles
Small heterocyclic compounds containing nitrogen and sulfur atoms, such as thiazole derivatives, represent a significant class of organic azoles that exhibit promising bioactivities and have a great potential in medicinal and agricultural fields. A convenient and high-yielding synthetic approach for a range of organic molecules is presented. The nuclease-like activities of compounds were studied with the aid of E. coli AB1157 DNA and agarose gel electrophoresis. The antioxidant evaluation of the compounds was carried out with different antioxidant techniques, such as ABTS and NO scavenging efficiency. The antibacterial behavior was evaluated against various bacterial strains, both Gram-positive and -negative, and the minimum inhibitory concentration (MIC) values of these compounds were determined. The antiproliferative activities and IC50 values of the synthesized organic molecules compounds against HEPG-2, MCF-7, and HCT-116 cell lines were evaluated
