Acute liver injury following Garcinia cambogia weight-loss supplementation: case series and literature review

Herbal weight-loss supplements are sold as self-medication products, and are often used under the misconception that their natural origin guarantees their safety. Food supplements are not required to provide any benefit/risk profile evaluation before marketing; however, possible risks associated with use of herbal extracts in food supplements are becoming more and more documented in the literature. Some herbs are listed as the leading cause of herb-induced liver injury, with a severe or potentially lethal clinical course, and unpredictable herb–drug interactions. Garcinia cambogia (GC) extract and GC-containing products are some of the most popular dietary supplements currently marketed for weight loss. Here, we present four cases of acute liver failure in women taking GC extract for weight loss, and a literature review of clinical evidences about hepatic toxicity in patients taking dietary supplements containing GC extract.

Risk of bone fractures among users of oral anticoagulants: An administrative database cohort study

• Occurrence of osteoporotic fracture in patients treated with oral anticoagulants was investigated.

Updating Diagnostic Test Accuracy Systematic Reviews: Which, When, and How Should They Be Updated?

Updating diagnostic test accuracy (DTA) systematic reviews (SRs) is fundamental in order to avoid making clinical decisions based on out-of-date and/or incomplete information. The decision of which SR to update should be based on the quality of the SR and on the currency of its topic. If SRs are considered worthy of updating, priority should first be established depending on the availability of elements of novelty (in terms of published studies, methodology, decisional approach, or standards of quality), as well as on the expected impact and value of information.

Efficacy of the anti-IL 17 secukinumab in refractory Behçet's syndrome: A preliminary study

OBJECTIVE To evaluate the efficacy and safety of secukinumab in Behçets patients with active mucocutaneous and articular manifestations refractory to previous treatments. METHODS We retrospectively evaluated 5 patients treated with the IL17-inhibitor secukinumab and diagnosed with Behçet according to ISG/ICBD criteria. All patients had active mucocutaneous and articular manifestations refractory to colchicine, conventional DMARDs and at least one anti-TNFα agent. Four patients received secukinumab in the dose of 150 mg/monthly since also fulfilling the criteria for ankylosing spondylitis, while the fifth patient received secukinumab 300 mg/monthly because she met psoriatic arthritis criteria. Achievement of response was based on the number of oral ulcers, BASDAI and ASDAS for articular involvement, and BDCAF for Behçet activity. Complete response was defined as: i) decrease ≥50% in the number of oral ulcers; ii) BASDAI index <4; iii) ASDAS index <1.4; iv) decrease of 50% or more in BDCAF index. RESULTS The patient starting secukinumab 300 mg/month successfully achieved complete response within 3 months. Complete response was maintained during all 9-months follow-up. Among the 4 subjects starting secukinumab 150 mg/month, two achieved complete response at month 6, but one relapsed. This patient and the two who not achieved complete response at month 6 were switched to secukinumab 300 mg/month. Within 3 months from the dosage increase, all three subjects successfully (re)achieved complete response. CONCLUSION Our study suggested for the first time that secukinumab (either 150 mg and 300 mg/month) improved active mucocutaneous manifestations refractory to previous treatments, while secukinumab 300 mg/monthly resulted superior in inducing articular and complete response in Behçets patients.

Subclinical atherosclerosis in asymptomatic carriers of persistent antiphospholipid antibodies positivity: A cross-sectional study

BACKGROUND Whereas the relationship between subclinical atherosclerosis and antiphospholipid syndrome (APS) has been widely investigated, little is known about subclinical atherosclerosis in asymptomatic carriers with isolated antiphospholipid antibodies positivity (APP). METHODS Consecutive APP carriers, APS subjects and matched controls were enrolled. Intima-media thickness of the common carotid artery (CCA-IMT) and of the Bulb (Bulb-IMT) and the prevalence of carotid plaques were assessed in all enrolled subjects. RESULTS A total of 104 APP carriers, 221 APS subjects, and 325 matched controls were recruited. As compared with controls, APP carriers and APS subjects showed a higher CCA-IMT (0.90 ± 0.24 vs 0.82 ± 0.12, p = 0.014 and 0.93 ± 0.42 vs 0.82 ± 0.12, p < 0.001, respectively), Bulb-IMT (1.10 ± 0.44 vs 0.95 ± 0.18, p = 0.006 and 1.22 ± 0.68 vs 0.95 ± 0.18, p < 0.001, respectively) and an increased prevalence of carotid plaques (33.7% vs 10.2%, p < 0.001 and 38.5% vs 10.2%, p < 0.001, respectively). These results were confirmed stratifying for antibody isotype, after excluding subjects with systemic lupus erythematosus or other autoimmune diseases and after adjusting for major clinical and demographic variables. CCA-IMT, Bulb-IMT and the prevalence of carotid plaques were higher in subjects with high-titer antibodies and progressively increased for an increasing number of positive antibodies. CONCLUSIONS Similar to APS subjects, APP carriers have enhanced subclinical atherosclerosis, a more severe disease being observed in the presence of high-titer antibodies and multiple antibodies positivity. These data argue for a strict monitoring of subclinical signs of atherosclerosis and of cardiovascular risk factors in asymptomatic APP carriers.

Impact of cardiovascular and immunologic variables on subclinical carotid atherosclerosis in subjects with anti-phospholipid antibodies

Whereas some previous data on carriers with isolated antiphospholipid antibodies positivity (APP) suggested an increased risk of arterial events in this clinical setting, no data are available on subclinical atherosclerosis in this clinical setting. This article reports data on intima-media thickness of the common carotid artery (CCA-IMT) and of the Bulb (Bulb-IMT) and on the prevalence of carotid plaques in APP carriers and in subjects with antiphospholipid syndrome (APS) specifically stratifying for the presence of thrombotic manifestations, cardiovascular risk factors, antibody isotype and concomitant Systemic Lupus Erythematosus (SLE) or other autoimmune diseases.

Prescribing patterns of allopurinol and febuxostat according to directives on the reimbursement criteria and clinical guidelines: analysis of a primary care database

Abstract Objective: According to American clinical guidelines, allopurinol and febuxostat may be prescribed as first-line therapy to treat hyperuricemia. However, the Italian Medicines Agency directive, called Nota 91, allows the reimbursement of second-line febuxostat in the case of failure and/or intolerance of a previous allopurinol therapy, so partially embracing European League Against Rheumatism recommendations and the British Society for Rheumatology Guideline. Such inconsistency might lead to heterogeneity among General Practitioners (GPs) in treatment of hyperuricemia. This study, therefore, aimed to evaluate the prescribing behavior of GPs in terms of compliance with Nota 91 and/or official guidelines. Methods: Using the Health Search Database, a retrospective cohort study was conducted to evaluate the patterns of use of allopurinol and febuxostat between 2011 and 2016. Results: In total, 44,257 and 5837 patients were prescribed with allopurinol and febuxostat, respectively. Among febuxostat users, 4321 (74%) had a previous allopurinol treatment; 92% of switches to febuxostat were related to hyperuricemia, whereas 9% of switchers presented intolerance to allopurinol; 26% of patients were prescribed with febuxostat as first-line therapy. The presence of diabetes and/or moderate/severe renal disease were statistically significant determinants of febuxostat use as first-line therapy. Conclusion: Prescriptions of febuxostat were highly compliant to Nota 91. Only a sub-group of frontline prescriptions of febuxostat were mainly driven by the presence of renal dysfunction, which is able to increase the risk of allopurinol intolerance and/or inefficacy. These findings indicate that GPs’ prescribing behavior for hyperuricemia is highly compliant with both regulatory directives and clinical guidelines.

The use of complementary and alternative medicines during breastfeeding: results from the Herbal supplements in Breastfeeding InvesTigation (HaBIT) study

The use of complementary and alternative medicines (CAMs) during breastfeeding is increasing, mainly because of their presumed greater safety compared with conventional medications. However, CAMs can cause serious adverse effects, and there is limited high‐quality evidence supporting their use during lactation. In Italy, specific investigations on the attitude of lactating women towards CAMs are lacking. The Herbal supplements in Breastfeeding InvesTigation (HaBIT) study aimed to explore attitudes to and knowledge on CAMs among lactating women.

The association of adjusted Global AntiphosPholipid Syndrome Score (aGAPSS) with cardiovascular disease in subjects with antiphospholipid antibodies

BACKGROUND AND AIMS Cardiovascular disease (CVD), including coronary artery disease and stroke/peripheral artery disease, is less commonly reported than venous thromboembolism in subjects with antiphospholipid antibodies (aPLs) and little is known about the association of CVD with adjusted Global AntiphosPholipid Syndrome Score (aGAPSS). METHODS Consecutive aPLs subjects were enrolled to assess the association of CVD with aGAPSS. Moreover, additional risk factors of CVD were identified by means of multivariate analysis to design an aGAPSS specific for CVD (aGAPSSCVD). RESULTS A total of 192 aPLs subjects (34 males, 158 females, mean age 49.84 ± 12.0 years) were enrolled. CVD was reported in 52 subjects (27.1%), 26 episodes of coronary artery disease and 26 stroke/peripheral artery disease. The prevalence of CVD increased for increasing aGAPSS ranging from 20.5% in the lowest aGAPSS category, up to 37.9% in the highest category (p = 0.027). ROC analysis showed that aGAPSS detected 63.0% of CVD and was associated with OR for CVD of 2.52 (95%CI: 1.24-5.10, p = 0.010). When including obesity, diabetes and smoking habit in the score, we found that aGAPSSCVD detected 71.4% of CVD (72.4% for early-CVD and 69.0% for CVD after 50 years) with an OR for CVD of 4.68 (95%CI: 2.31-9.51, p < 0.001). CONCLUSIONS The aGAPSSCVD, obtained after adding obesity, smoking habit and diabetes to the standard aGAPSS, showed a higher detection rate of CVD in aPLs subjects, particularly of early-CVD. These results need to be validated in ad hoc designed prospective studies.

Adalimumab-Based Treatment Versus Disease-Modifying Antirheumatic Drugs for Venous Thrombosis in Behçet's Syndrome: A Retrospective Study of Seventy Patients With Vascular Involvement

Since Behçets syndrome (BS) is the prototype of inflammation‐induced thrombosis, immunosuppressants are recommended in place of anticoagulants. We undertook this study to assess the clinical efficacy and the corticosteroid‐sparing effect of adalimumab (ADA)–based treatment versus disease‐modifying antirheumatic drug (DMARD) therapy in a large retrospective cohort of patients with BS‐related venous thrombosis.
