Areas covered: Previous and recent studies have evaluated several synthetic drugs in the treatment of SLE. This article reviews currently available evidence for the efficacy and safety of synthetic drugs in SLE and discusses future treatment perspectives.
Expert opinion: Hydroxychloroquine should be considered an anchor drug in SLE because of the multiple beneficial effects of this agent. When patients present with persistent disease activity despite hydroxychloroquine therapy or need higher dosages and/or prolonged use of glucocorticoids (GCs), additional immunosuppressants should be promptly prescribed. Based on available evidence, azathioprine and mycophenolate mofetil are the drugs of first choice. Determination of a ‘safe’ GC dose for chronic daily use is of major importance and should be subject of further studies in large patient populations. 相似文献
Objective: To describe the first case of a patient with a spontaneous corneal perforation associated with mucocutaneous ulcerations while taking Nicorandil.
Materials and methods: A 81-year-old patient, with no past history of ocular disease but a long past history of cardiovascular disease, presented with a spontaneous paracentral corneal perforation. This was consecutive to 5 months of recurrent keratoconjunctivitis and mucocutaneous ulcerations resistant to conventional therapy. (He was taking nicorandil for 5 years.) A penetrating keratoplasty was performed in emergency.
Results: Inflammatory and infectious causes of spontaneous corneal perforation were ruled out. After initial uneventful post-operative wound healing, an epithelial ulcer appeared on the graft. Dermatologists suggested the iatrogenic role of nicorandil and the drug was discontinued. Both mucocutaneous and corneal ulcerations resolved rapidly.
Discussion: Although mucocutaneous ulcerations have been attributed several times to nicorandil, this is, to our knowledge, the first major corneal damage due to this antianginal drug. Timing, pattern of illness, absence of other aetiology, recurrence of epithelial ulceration on the corneal graft and its spontaneous healing after nicorandil discontinuation make it highly apparent probable that nicorandil was directly involved in this corneal perforation.
Conclusion: Ophthalmologists and dermatologists should be aware of the risk of severe but reversible corneal ulcerations in patients treated with nicorandil. A pharmacovigilance warning statement should be compulsory. 相似文献
Materials and methods: Pediatric patients with brucellosis that were treated between February 2014 and January 2016 were analyzed retrospectively, and those that developed doxycycline-related cutaneous side effects were identified. Demographic data, epidemiological history, physical examination findings, laboratory test results, anti-brucellosis treatment regimen, duration of follow up and outcome were recorded.
Results: Among the 189 brucellosis patients, 141 treated with doxycycline plus rifampicin. Seven patients (5%) (two female and five male) developed doxycycline-related cutaneous side effects. Mean duration of treatment before the onset of cutaneous side effects was 9.5 weeks. Doxycycline therapy was continued in five of these patients and was changed in two patients. In the patients that continued to receive doxycycline the cutaneous side effects gradually improved.
Conclusions: Cutaneous side effects of doxycycline should always be a consideration, especially in regions in which brucellosis is endemic and doxycycline is commonly used to treat it. 相似文献
Areas covered: There is considerable concern about increased incidence of pneumonia, osteoporosis and hyperglycemia in diabetic patients and cataracts. The local side effects of ICSs, such as hoarseness and pharyngeal discomfort, oral and oropharyngeal candidiasis, cough during inhalation, and a sensation of thirst, are not usually serious but are of clinical importance because they may lead to patients discontinuing therapy.
Expert opinion: The possibility that ICSs induce adverse side effects should not lead us to avoid their use in patients in whom clinical evidence suggests that they may be helpful. However, clinicians should balance the potential benefits of ICSs in COPD against their potential side effects and always consider using the lowest possible dose to achieve the best possible management. 相似文献
Research design and methods: Multicenter survey, open-label study of 49 Japanese COPD patients aged ≥ 40 years; outpatients with >10 pack years of smoking history; ratio of forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) < 70%; predicted FEV1 < 80%; treated with bronchodilators and/or inhaled corticosteroids as maintenance therapy until week 48.
Main outcome measures: The primary endpoint was change in pulmonary function (trough FEV1, trough FVC); secondary endpoints were QOL and physical activity at 48 weeks after initiation of therapy.
Results: Airway reversibility was confirmed in untreated patients. Significant changes over time were not observed for FEV1 and FVC, indicating lung function at initiation of treatment was maintained during the observation period. COPD assessment test scores showed statistical and clinical improvements. Cough, sputum, breathlessness, and shortness of breath were significantly improved.
Conclusions: Lung function and QOL of untreated Japanese COPD patients improved and improvements were maintained by performing a therapeutic intervention that conformed to published guidelines. 相似文献
Areas covered: We performed an analysis of a recent study evaluating the efficacy and safety of inhaled indacaterol versus inhaled salmeterol/fluticasone in COPD patients.
Expert opinion: Both therapies were found to exert comparable effects on lung function, symptom severity and health status. 相似文献
Objective: Identification of compounds from C. rotundus rhizomes responsible for the inhibition of α-glucosidase and α-amylase.
Materials and methods: Compounds were identified by a phytochemical investigation using combined chromatographic and spectroscopic methods. α-glucosidase and α-amylase inhibitory activities were evaluated by in vitro enzyme inhibition assays.
Results: A new (2RS,3SR)-3,4′,5,6,7,8-hexahydroxyflavane (1), together with three known stilbene dimers cassigarol E (2), scirpusin A (3) and B (4) were isolated. Compound 2 inhibited both α-glucosidase and α-amylase activities while the flavane 1 only showed effect on α-amylase, and compounds 3 and 4 were active on α-glucosidase. All four compounds showed significant 2,2-diphenyl-1-picrylhydrazyl (DPPH) scavenging activity.
Discussion: The inhibitory activities against α-amylase and α-glucosidase of the C. rotundus rhizomes were reported for the first time. Stilbene dimers are considered as potent inhibitors of α-glucosidase and promising antihyperglycemic agents.
Conclusion: The isolated compounds may contribute to the antidiabetic property of C. rotundus. 相似文献
Areas covered: Herein, we review the most common drugs used in the treatment of renal stones, explaining the mechanism of action and potential side effects. Search of the Medline databases and relevant textbooks was conducted to obtain the relevant information. Further details were sourced from drug prescribing manuals. Recent studies of drug effectiveness are included as appropriate.
Expert opinion: Recent controversies include medical expulsive therapy trials and complex role of urinary citrate in stone disease. Future directions in research will involve new medical therapies for stone prevention, for example new drugs for hyperoxaluria. 相似文献
Areas covered: This review summarizes traditional and emerging risk factors of CVD in SLE patients and goes over potential pathogenic mechanisms involved in CVD development. Role of commonly used drugs and preventive strategies exploitable in everyday clinical practice are also discussed.
Expert opinion: SLE-related risk factors involve both disease- and treatment-related features, including disease activity, disease phenotype, corticosteroid misuse and alterations of innate and adaptive immunity. Primary prevention is mandatory in management of lupus patients through appropriate disease control, corticosteroid tapering, use of antimalarials and eventually vitamin D supplementation. 相似文献
Research design and methods: We utilized a hospital claims database containing 36,504 Japanese patients with a confirmed RA diagnosis. To analyze the determinants of treatment choices, we applied logistic regression analysis taking into account socio-demographic and medical factors.
Results: Analyses determined that 11.8% of diagnoses and 25.4% of treated patients in Japan receive a biologic agent. Significant factors associated with biologic treatment initiation include younger age, female sex, and a higher comorbidity index. The route of administration plays a major role when it comes to a switch between different biologic agents.
Conclusions: The lower likelihood of elderly patients to be initiated on biologic treatment might be explained by the risk aversion of Japanese physicians’ and patients who are afraid of the potential side effects of biologics. This finding is also consistent with the notion of an age bias that impedes elderly patients from optimal access to biologic treatment. Because claims data does not contain clinical parameters such as disease activity the results should be validated in a clinical context. 相似文献
Areas covered: Published clinical studies involving topical and oral FDA approved medications for AD are included in this review. Authors used PubMed research database to search for clinical trials involving AD patients.
Expert opinion: AD is a common disease which currently has limited FDA approved medications. Given the chronicity of this disease, medications are needed which control disease while minimizing side effects to allow for long term use. Newer approved medications show promise but safety data is limited given their relatively new utilization for AD. 相似文献
Research design and methods: This retrospective study included 194 ABC patients who received fulvestrant (500 mg) from January 2012 to December 2014.
Main outcome measures: TTF (efficacy measure), overall survival (OS), factors prolonging TTF and adverse events were evaluated.
Results: The median age was 65 (42 – 90) years. Overall, TTF was 5.48 months. In patients without prior chemotherapy (n = 59), OS was significantly longer (p = 0.0131) than in patients with prior chemotherapy (n = 135). There was no strong correlation between TTF with fulvestrant and other endocrine therapies, total duration of endocrine therapy and maximum duration of endocrine therapy. TTF was significantly longer in patients with less than two prior chemotherapy regimens (p = 0.0093), de novo metastatic disease (p = 0.0124) and without liver metastasis (p = 0.0024). We observed one case each of pulmonary infarction and psychiatric disorder.
Conclusions: Fulvestrant is effective for ABC patients and may show greater efficacy in patients with few prior chemotherapy regimens, de novo metastatic disease and absence of liver metastasis. Prior endocrine therapy duration might not be a predictive factor for fulvestrant TTF in heavily treated ABC patients. 相似文献
Objective: This study aimed to determine the protective effects of the osmolyte taurine against blue light-induced apoptosis in retinal neuronal cells in vitro.
Methods: Real-time PCR was used to measure osmolyte transport. Radioimmunoassays were performed to measure osmolyte uptake. Cell Counting Kit-8 assays were conducted to measure cellular viability. Flow cytometry analysis was used to measure apoptosis.
Results: Compared with normotonic stress, hypertonic stress-induced uptake of osmolytes, including betaine, myoinositol, and taurine, into the retinal neuronal cells. Blue light increased osmolyte transporter mRNA expression together with osmolyte uptake. Furthermore, taurine significantly suppressed blue light-induced retinal neuronal cell apoptosis.
Conclusion: The compatible osmolyte taurine may have an important role in cell resistance to blue light and cell survival. 相似文献
Objective: This review aims to evaluate the efficacy and safety of compound glycyrrhizin in combination with conventional therapy for psoriasis vulgaris.
Methods: PubMed, Excerpta Medica dataBASE (Embase), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials, Allied and Complementary Medicine Database (AMED), CiNii, Chinese Biomedical Literature, China National Knowledge Infrastructure, Chinese Scientific Journals Full Text Database and Wanfang Data were searched from their respective inceptions to July 2015. Randomized controlled trials comparing compound glycyrrhizin plus conventional therapy to conventional therapy alone for psoriasis vulgaris were included. Data analysis was performed using Review Manager 5.3.
Results: Eleven randomized controlled trials were included in this review. Meta-analysis of the 11 randomized controlled trials indicated that the addition of compound glycyrrhizin increased the number of patients achieving Psoriasis Area and Severity Index (PASI) 60 (RR: 1.30 [1.21, 1.40], I2 = 6%), when compared with conventional therapy alone. Comparable numbers of patients experienced adverse events in the two groups.
Conclusions: Compound glycyrrhizin in conjunction with conventional therapy enhances clinical response, and compound glycyrrhizin as add-on therapy does not appear to pose any additional risk in the treatment of psoriasis vulgaris. However, the findings should be interpreted with caution of methodological flaws in the included studies.

Objective: This article elaborates on studying the activity of medicinal plants against different forms of Mycobacterium tuberculosis (Mtb) using different model strains, in vitro and ex vivo assays for studying the tuberculocidal activity and discusses the results from different studies on the activity against different forms of Mtb and human immunodeficiency virus-tuberculosis (HIV-TB) co-infection.
Methods: Scientific databases such as PubMed, Elsevier, Scopus, Google scholar, were used to retrieve the information from 86 research articles (published from 1994 to 2016) related to the topic of this review.
Results: Twenty-three plant species have been reported to possess active molecules against multi-drug resistant (MDR) isolates of Mtb. Seven plants were found to be active against intracellular Mtb and six against dormant bacilli. Seven plants were synergistically effective when combined with anti-TB drugs. Six studies suggest that the beneficial effects of plant extracts are due to their wide array of immuno-modulatory effects manifested by the higher expression of cytokines. Some studies have also shown the dual activity (anti-HIV and anti-TB) of plants.
Conclusion: We emphasize on identifying plants based on traditional uses and testing their extracts/phytomolecules against MDR strains, intracellular Mtb as well as against dormant Mtb. This will help in future to shorten the current therapeutic regimens for TB and also for treating HIV-TB co-infection. 相似文献
Areas covered: Since platinum free interval (PFI) represents the most important predictive factor for response to platinum re-treatment in ROC, non-platinum regimens are conventionally considered the most appropriate approaches.
Impressive progress has been made in recent decades, resulting in the identification of most effective cytotoxic agents and in the development of new target strategies.
However, the efficacy of most of these drugs for the treatment of PR disease is still limited.
Expert opinion: The most favorable benefit for the treatment of PR disease, has been described by the AURELIA trial that showed a 3.3 months increase in progression free survival (PFS) when bevacizumab was combined with non-platinum single agent chemotherapy in bevacizumab-naïve patients.
Nevertheless, the use of novel agents is associated to important costs for just little gains in survival.
Thus, in our opinion the economic evaluation, such as the incorporation of quality of life into the clinical studies is crucial for the development of future trials for PR-ROC. 相似文献
Areas covered: We performed a literature search on PubMed using the following key words: anemia, chronic kidney disease, HIF stabilisers, sotatercept, actin traps, iron, iron-containing phosphate binders, iron dialysate. We reviewed new drugs that are under clinical development to obtain better safety and activity and/or easier and cheaper manufacturing processes in comparison to available ESAs. We also considered new strategies to increase iron stores.
Several phase 1 and 2 studies support the beneficial role of increasing Hypoxia Inducible factor (HIF) activity for stimulating endogenous erythropoiesis. Sotatercept and luspatercept, two activin traps, are undergoing clinical development mainly for indications other than CKD. They have the additional effect of improving osteoporosis. Iron-containing phosphate binders have become available recently.
Expert opinion: Several medical needs are unmet with ESA. HIF stabilisers are the most appealing drugs undergoing clinical development. They expose patients to lower levels of EPO than ESA, possibly reducing unintended effects. Their long-term safety is still to be demonstrated. One new iron-containing phosphate binders has the potential of combining two indications: hyperphosphoremia and iron deficiency, possibly improving compliance. 相似文献
Purpose: Hyaluronic acid (HA)-modified daunorubicin plus honokiol (HNK) cationic liposomes were prepared and characterised for treatment of breast cancer by eliminating VM.
Methods: HA-modified daunorubicin plus HNK cationic liposomes were prepared by a thin-film hydration method. Evaluations were performed on MCF-7 cells and MDA-MB-435S cells, which are human breast cancer cells, and xenografts of MDA-MB-435S cells.
Results: In vitro results revealed that the HA-modified daunorubicin plus HNK cationic liposomes enhanced the cellular uptake and destroyed VM channels. In vivo results demonstrated that the liposomes prolonged the circulation time in the blood, obviously accumulated in the tumour region, and enhanced the overall anticancer effects. Action mechanisms were related to down-regulation of VM protein indicators including FAK, EphA2, MMP-2 and MMP-9.
Conclusions: The prepared HA-modified daunorubicin plus HNK cationic liposomes may serve as a promising therapeutic strategy for the treatment of breast cancer. 相似文献
Areas covered: Besides the well-known adverse effects on joints and bone and the vasomotor system, more neglected and latent toxicity like cognitive problems and vulvovaginal atrophy will be discussed. Concern has been raised in terms of increased risk of fractures and cardiovascular events with chronic AI use.
Expert opinion: Placebo-controlled long-term studies carefully monitoring these adverse events, together with more extensive research in the etiologies, are warranted. 相似文献
