IntroductionThe diagnosis of latent tuberculous infection (LTI) by IGRA continues to generate debate. Experience in the simultaneous use of 2 IGRA tests is scant. The aim of this study was to compare the results of 2 versions of QuantiFERON-TB Gold (In-Tube/Plus) with those of T-SPOT.TB, and to analyse the effectiveness of a dual strategy (T-SPOT.TB + QTF) for the diagnosis of LTI in an immunosuppressed population.MethodsWe conducted a prospective study (May 2015-June 2017) that included 2,999 immunosuppressed patients and/or candidates for biologics, in whom 2 simultaneous IGRA tests were performed: Group 1 (1535 patients): T-SPOT.TB + QuantiFERON-TB Gold-In-Tube (QTF-GIT); Group 2 (1464 patients): T-SPOT.TB + QuantiFERON-TB Gold Plus (QTF-Plus).ResultsThe concordance between QTF-GIT and T-SPOT.TB was 83.19% (κ=0.532). The percentage of positive, negative, and indeterminate results were, respectively: 14.33% vs. 17.06%; 82.41% vs. 74.46%; and 3.25% vs. 8.46%. The concordance between QTF-Plus and T-SPOT.TB was 87.56% (κ=0.609). The percentage of positive, negative, and indeterminate results were, respectively: 15.02% vs. 15.36%; 82.92% vs. 79.37%; and 2.04% vs. 5.25%. Discrepancies between T-SPOT.TB and QTF-Plus were 12.43%, suggesting that 103 patients were positive and another 79 were negative due exclusively to 1 of the 2 IGRAs.ConclusionsGreater concordance was found between QTF-Plus and T-SPOT.TB than between QTF-GIT and T-SPOT.TB. However, we believe that the proportion of discrepancies between T-SPOT.TB and QTF-Plus is sufficiently important from a clinical point of view to justify the simultaneous use of 2 IGRA in this specific patient group. 相似文献
Objective: There is a need to identify safe and effective opioid-sparing multimodal alternative treatment strategies and approaches, including topical analgesics, for opioid-experienced chronic pain patients to mitigate the risk of addiction, misuse, and abuse of opioids.
Methods: This subset analysis from a prospective, observational study evaluated changes in opioid use, other concurrent medication use, and pain severity and interference in opioid-experienced patients (OEP) treated with topical analgesics for chronic pain with measures obtained at baseline and 3- and 6- month follow-up.
Results: The 3-month opioid-experienced patient (3-month OEP) group included 121 patients who completed baseline and 3-month follow-up assessments; 27 opioid-experienced patients completed baseline and 6-month follow-up assessments (6-month OEP). Demographic characteristics, and mean pain severity and interference scores were similar between groups at baseline. After treatment with topical analgesics, 49% of patients in the 3-month and 56% of patients in the 6-month group reported they had completely discontinued use of opioids. In addition, 31% of patients at the 3-month assessment and 30% at the 6-month assessment reported that they were no longer taking any pain medication. Other concurrent medications decreased by 65% after 3 months, and 74% after 6 months. There were statistically significant decreases from baseline in pain severity and interference scores within the 3- (CI:0.7–1.4, 1.4–2.2) and 6-month (CI:0.7–2.4 (severity); CI:1.2–3.5 (interference)) OEP groups.
Conclusions: Opioid use and other concurrent medications decreased among opioid-experienced chronic pain patients after 3- and 6- months of treatment with topical analgesics. Pain severity and interference scores also decreased. The topical analgesics were reported to be effective and safe for the treatment of chronic pain, with randomized controlled trials needed to confirm these findings. 相似文献
To evaluate the evidence of the effectiveness and safety of Chinese herbal medicine skin‐patches for patients with acute gouty arthritis.
Background
Acute gouty arthritis is a problem that can limit the level of activity and impair the quality of life. In China, many clinical studies have demonstrated that skin‐patches of Chinese herbal medicines benefit patients with acute gouty arthritis. However, the reported clinical effects vary.
Design
A systematic review and meta‐analysis of randomized controlled trials.
Data sources
Three English databases including CENTRAL (1993 to February 2017), PubMed (1966 to February 2017) and EMBASE (1974 to February 2017) and four Chinese databases including Chinese National Knowledge Infrastructure, Chinese VIP Information, SinoMed and Wanfang (all, 1949 ‐ February 2017) were searched. Randomized controlled trials that compared skin‐patches of Chinese herbal medicine with or without conventional treatments to conventional treatments, no treatment or a placebo treatment for patients with acute gouty arthritis were included.
Review methods
We conducted a systematic review and meta‐analysis following the Cochrane process. Two authors selected the studies, extracted the data and evaluated the risk of bias of the included trials.
Results
Nineteen studies met our inclusion criteria. After synthesizing the data, the results showed that skin‐patches of CHM combined with Western medicine seemed to be more effective than Western medicine alone for pain relief in patients with acute gouty arthritis and had fewer adverse events.
Conclusion
Due to the quality of the data, larger and more rigorously designed clinical trials with proper outcome measures are necessary. 相似文献
Lesions caused by verrucus vulgaris are commonly refractory to therapy and may become large, painful, or disfiguring in immunocompromised patients. Cidofovir is a potent nucleoside analog antiviral agent shown to have in vitro and in vivo activity against a broad spectrum of DNA viruses. We report a successful use of topical cidofovir to treat verruca vulgaris lesions in a highly immunocompromised patient, who was not considered a candidate for conventional therapy. 相似文献
ABSTRACTIntroduction: Acne vulgaris is a widespread skin disease. Topical therapy is a standard treatment for mild to moderate acne. Given the complex pathophysiology of acne, various agents with complementary action are nowadays frequently combined to increase the efficacy of therapy.Area covered: This review focus on safety profile of topical agents used for the treatment of acne vulgaris, including topical retinoids, benzyl peroxide, azelaic acid, topical antibiotic, and combined agents. Data from clinical trials but also metanalyses, systematic reviews, and other secondary analyses are presented.Expert opinion: In general, topical agents used for acne vulgaris have a favorable safety profile. The most commonly reported AEs were associated with local skin irritation, usually mild to moderate in intensity, intermittent, and rarely led to the cessation of therapy. Irritative potential seems to be highest for BPO and topical retinoids. Due to the possibility of development of Cutibacterium acnes resistance, topical antibiotics should not be used in monotherapy but as a part of combination therapy. In female adolescent and adults of childbearing potential, topical retinoids should be used with caution, because they are contraindicated in pregnant females (FDA Pregnancy category) C (adapalene, tretinoin) and X (tazarotene). 相似文献
Background: The aim was to investigate cutaneous delivery and biodistribution of the hedgehog pathway inhibitor, vismodegib (VSD), indicated for basal cell carcinoma (BCC), from polymeric micelle formulations under infinite/finite dose conditions.Methods: VSD-loaded micelles were characterized for drug content, particle size, and shape; a micelle gel was characterized for its rheological behavior. Cutaneous deposition and biodistribution of VSD were determined using porcine and human skin in vitro with quantification by UHPLC-MS/MS.Results: The optimal micelle solution (Zav 20–30 nm) increased the aqueous solubility of VSD by >8000-fold; drug content was stable after 4 weeks at 4°C. Application of micelle solution and micelle gel (0.086% w/v) to human skin for 12 h under infinite dose conditions resulted in statistically equivalent VSD deposition (0.62 ± 0.11 and 0.67 ± 0.14 μg/cm2, respectively). Cutaneous biodistribution in human skin under infinite (micelle solution and gel) and finite (micelle gel) dose conditions showed that the VSD concentrations obtained in the basal epidermis, at depths of 120–200 μm, were ?3800- and ?2300-fold greater than the IC50 reported for hedgehog signaling pathway inhibition in vitro.Conclusion: Cutaneous delivery of VSD from micelle-based formulations might enable targeted, topical treatment of superficial BCC with minimal risk of systemic exposure. 相似文献
