The efficacy, safety and carry-over effect of diacerein in the treatment of painful knee osteoarthritis: a randomised, double-blind, NSAID-controlled study

SummaryObjectiveTo evaluate the efficacy, safety and carry-over effect of diacerein, in comparison to piroxicam, in the treatment of Thai patients with symptomatic knee osteoarthritis (OA).DesignThis was a double-blind, randomised, piroxicam-controlled, parallel-group study. A 7-day non-steroidal anti-inflammatory drug washout period was followed by a 16-week treatment period with either diacerein 100mg/day or piroxicam 20mg/day, and an 8-week treatment-free observation period. The primary efficacy criterion was pain on Western Ontario and McMaster University Osteoarthritis (WOMAC) A. The secondary criteria included WOMAC B, C and total WOMAC, paracetamol intake, Short Form-36 questionnaire and global judgements on efficacy and tolerability by patients and investigators.ResultsOf 171 randomised patients, 150 completed the study and 161 were analysed in the intent-to-treat population (diacerein: 82, piroxicam: 79). Pain (WOMAC A) decreased to a similar extent in both groups at Week 16 (diacerein: −69.7%±31.5%; piroxicam: −74.1±26.2%; P=n.s.). On treatment discontinuation, pain increased in the piroxicam group at Weeks 20 (−47%±47.8%) and 24 (−26.8%±60.6%) while improvements persisted in the diacerein group at Weeks 20 (−66.9%±35.9%) and 24 (−69.5%±33.7%), with a significant difference in favour of diacerein at Weeks 20 and 24, demonstrating the carry-over effects of the drug. The incidence of adverse events was similar in both groups but more patients from the piroxicam group dropped out of the study due to these events.ConclusionsDiacerein was as effective as piroxicam in reducing pain and improving function but, unlike piroxicam, displayed a carry-over effect and a better safety profile

Immune reconstitution inflammatory syndrome from Penicillium marneffei in an HIV-infected child: a case report and review of literature

<p>Abstract</p> <p>Backgrounds</p> <p>Disseminated <it>Penicillium marneffei </it>infection is one of the most common HIV-related opportunistic infections in Southeast Asia. Immune reconstitution inflammatory syndrome (IRIS) is a complication related to antiretroviral therapy (ART)-induced immune restoration. The aim of this report is to present a case of HIV-infected child who developed an unmasking type of IRIS caused by disseminated <it>P. marneffei </it>infection after ART initiation.</p> <p>Case presentation</p> <p>A 14-year-old Thai HIV-infected girl presented with high-grade fever, multiple painful ulcerated oral lesions, generalized non-pruritic erythrematous skin papules and nodules with central umbilication, and multiple swollen, warm, and tender joints 8 weeks after ART initiation. At that time, her CD4⁺cell count was 7.2% or 39 cells/mm³. On admission, her repeated CD4⁺cell count was 11% or 51 cells/mm³and her plasma HIV-RNA level was < 50 copies/mL. Her skin biopsy showed necrotizing histiocytic granuloma formation with neutrophilic infiltration in the upper and reticular dermis. Tissue sections stained with hematoxylin and eosin (H&E), periodic acid-Schiff (PAS), and Grocott methenamine silver (GMS) stain revealed numerous intracellular and extracellular, round to oval, elongated, thin-walled yeast cells with central septation. The hemoculture, bone marrow culture, and skin culture revealed no growth of fungus or bacteria. Our patient responded well to intravenous amphotericin B followed by oral itraconazole. She fully recovered after 4-month antifungal treatment without evidence of recurrence of disease.</p> <p>Conclusions</p> <p>IRIS from <it>P. marneffei </it>in HIV-infected people is rare. Appropriate recognition and properly treatment is important for a good prognosis.</p

Inflammatory arthritis in HIV positive patients: A practical guide

Background: Musculoskeletal manifestations of the human immunodeficiency virus (HIV) have been described since the outset of the global HIV epidemic. Articular syndromes that have been described in association with HIV include HIV-associated arthropathy, seronegative spondyloarthropathies (SPA) (reactive arthritis, psoriatic arthritis (PsA) and undifferentiated SPA), rheumatoid arthritis (RA) and painful articular syndrome. Methods: We carried out a computer-assisted search of PubMed for the medical literature from January 1981 to January 2015 using the keywords HIV, acquired immune-deficiency syndrome, rheumatic manifestations, arthritis, spondyloarthropathy, anti-TNF and disease modifying antirheumatic drugs. Only English language literature was included and only studies involving adult human subjects were assessed. Results: There are challenges in the management of inflammatory arthritis in patients who are HIV-positive, including difficulties in the assessment of disease activity and limited information on the safety of immunosuppressive drugs in these individuals. Conclusions: This review focuses on the clinical characteristics of the inflammatory articular syndromes that have been described in association with HIV infection and discusses the therapeutic options for these patients

Factors associated with parasympathetic activation following exercise in patients with rheumatoid arthritis: a cross-sectional study

Background Patients with rheumatoid arthritis (RA) have an increased risk for cardiovascular disease (CVD) with poor parasympathetic function being implicated as an underlying factor. Factors related to parasympathetic function, commonly assessed by heart rate recovery (HRR) following maximal exercise, are currently not known in RA. We aimed to explore the association between HRR with CVD risk factors, inflammatory markers, and wellbeing in patients with RA. Methods Ninety-six RA patients (54.4 ± 12.6 years, 68 % women) completed a treadmill exercise test, during which heart rate (HR) was monitored. HRR1 and HRR2 were defined as the absolute change from HR peak to HRR 1 min post HR peak and 2 min post HR peak, respectively. Cardiorespiratory fitness, CVD risk factors, and serological markers of inflammation were measured in all patients. The Framingham Risk Score (FRS) was used as an assessment of global risk for CVD events, and wellbeing was assessed by questionnaires. Results Mean HRR1 and HRR2 were 29.1 ± 13.2 bpm and 46.4 ± 15.3 bpm, respectively. CVD risk factors as well as most inflammatory markers and measures of wellbeing were inversely correlated with HRR1 and HRR2. Multivariate regression analyses revealed that 27.9 % of the variance in HRR1 and 37.9 % of the variance in HRR2 was explained collectively by CVD risk factors, measures of inflammation, and wellbeing (p = 0.009, p = 0.001 respectively), however no individual measure was independently associated with HRR1 or HRR2. Conclusion Parasympathetic activation was associated with overall CVD risk, arthritis-related burden and wellbeing in patients with RA

Prevalence and predictors of depression in patients with systemic lupus erythematosus: a cross-sectional study

Benchalak Maneeton,1 Narong Maneeton,1 Worawit Louthrenoo2 1Department of Psychiatry, 2Department of Medicine, Faculty of Medicine, Chiang Mai University, Chiang Mai, Thailand Objective: The purpose of this study was to estimate the prevalence and examine the predictors of depression in patients with systemic lupus erythematosus (SLE). Methods: This cross-sectional study was conducted in the rheumatology clinic of a university hospital. All SLE patients that met the revised American College of Rheumatology (ACR) classification were included in the study. Sociodemographic data and medications were recorded. Disease activity for SLE was assessed with the Mexican-SLE Disease Activity Index (Mex-SLEDAI). All subjects were screened for anxiety and depression by using the Hamilton Anxiety Rating Scale (HAM-A) and the 17-item version of the Hamilton Depression Rating Scale (HAM-D17). Multiple linear regression analyses were used to determine predictors of depressive disorder. Results: A total of 62 SLE (61 females and 1 male) patients participated in the study. Based on HAM-D17 and HAM-A, rates of depression and anxiety in SLE patients were 45.2% and 37.1%, respectively. The multiple linear regression analysis revealed that HAM-A score and younger age were significant predictors of depression in SLE patients. Conclusion: The findings suggest that depression and anxiety are common in SLE patients. In addition, higher levels of anxiety and a younger age may increase the risk of depression. Because of the small sample size, further studies should be conducted to confirm these results. Keywords: systemic lupus erythematosus, depression, anxiety disorde
