RESUMEN

BACKGROUND: Addressing sexual trauma in the context of HIV care is essential to improve clinical outcomes and mental health among women in South Africa. Women living with HIV (WLH) report disproportionately high levels of sexual trauma and have higher rates of posttraumatic stress disorder. Adherence to antiretroviral therapy (ART) may be difficult for traumatized women, as sexual trauma compounds the stress associated with managing HIV and is often comorbid with other mental health disorders, further compromising care engagement and adherence. ART initiation represents a unique window of opportunity for intervention to enhance motivation, increase care engagement, and address the negative effects of trauma on avoidant coping behaviors. Mental health interventions delivered by non-specialists in low- and middle-income countries have potential to treat depression, trauma, and effects of intimate partner violence among WLH. This study will examine the effectiveness of Improving AIDS Care after Trauma (ImpACT +), a task-shared, trauma-focused coping intervention, to promote viral suppression among WLH initiating ART in a South African clinic setting. METHODS: This study will be conducted in Khayelitsha, a peri-urban settlement situated near Cape Town, South Africa. Using a hybrid type 1 effectiveness-implementation design, we will randomize 350 WLH initiating ART to the ImpACT + experimental condition or the control condition (three weekly sessions of adapted problem-solving therapy) to examine the effectiveness of ImpACT + on viral suppression, ART adherence, and the degree to which mental health outcomes mediate intervention effects. ImpACT + participants will receive six once-a-week coping intervention sessions and six monthly maintenance sessions over the follow-up period. We will conduct mental health and bio-behavioral assessments at baseline, 4, 8, and 12 months, with care engagement data extracted from medical records. We will explore scalability using the Consolidated Framework for Implementation Research (CFIR). DISCUSSION: This trial is expected to yield important new information on psychologically informed intervention models that benefit the mental health and clinical outcomes of WLH with histories of sexual trauma. The proposed ImpACT + intervention, with its focus on building coping skills to address traumatic stress and engagement in HIV care and treatment, could have widespread impact on the health and wellbeing of individuals and communities in sub-Saharan Africa. TRIAL REGISTRATION: Clinicaltrials.gov NCT04793217 . Retrospectively registered on 11 March 2021.

RESUMEN

Screening measures for depression developed in high-income countries have not always demonstrated strong psychometric properties in South Africa and with people living with HIV (PLWH). The present study explored the psychometric properties of the 16-item South African Depression Scale (SADS) comprised of idioms of distress specific to isiXhosa culture in PLWH. The SADS was administered to 137 Xhosa-speaking PLWH who met diagnostic criteria for major depressive disorder (MDD) together with the Hamilton Depression Scale (HAM-D) and the Center for Epidemiological Studies Depression Scale (CES-D). We conducted exploratory factor analysis, correlation, and reliability statistics. Four factors of the SADS emerged: Sadness, lethargy/burdened, anhedonia/withdrawal, and cognitive/somatic. All factors correlated significantly with the HAM-D and CES-D. Internal consistency of the overall measure was high (α = .89). The SADS promises to be a robust measure of depression in isiXhosa-speaking PLWH in South Africa likely due to the inclusion of local idioms of distress.

RESUMEN

There is a need for a culturally adapted, evidence-based, psychotherapy treatment that is effective, acceptable, and feasible for integration into primary care in South Africa. This qualitative study used exit interviews to examine participants' experiences of an adapted cognitive-behavioural therapy treatment for adherence and depression, task-shifted and delivered by nurses in two peri-urban HIV clinics near Cape Town. Nine semi-structured exit interviews were conducted with isiXhosa-speaking females and analysed using thematic analysis. Overall, participants responded positively to the treatment, viewing it as acceptable and beneficial and as a catalyst to returning to normalcy. Results indicated that participants viewed the treatment as being effective in ameliorating their depressive symptoms and improving their adherence to ART . Additional benefits described included improvements in subjective wellbeing and social and occupational functioning. Several began or resumed employment, an important behavioural indicator of the treatment's capacity to facilitate positive change and cost saving. Recommendations to improve the treatment included using video material and educating others about depression. These findings have positive implications regarding the acceptability and cultural applicability of the treatment for use in South Africa.

RESUMEN

OBJECTIVES: To investigate whether a treat-to-target strategy based on methotrexate (MTX) and intra-articular (IA) betamethasone suppresses magnetic resonance imaging (MRI)-determined measures of disease activity and reduces joint destruction in early rheumatoid arthritis (eRA) patients, and to investigate whether concomitant cyclosporin A (CyA) provides an additional effect. METHOD: In the 2-year randomized, double-blind, treat-to-target trial CIMESTRA, 160 patients with eRA (< 6 months) were randomized to MTX, intra-articular betamethasone and CyA, or placebo CyA. A total of 129 patients participated in the MRI substudy, and had contrast-enhanced MR images of the non-dominant hand at months 0, 6, 12, and 24. MR images were evaluated for osteitis, synovitis, tenosynovitis, bone erosion, and joint space narrowing (JSN), using validated scoring methods. RESULTS: Significant reductions were seen at 6 months in all inflammatory parameters [synovitis, mean change -1.6 (p < 0.001, Wilcoxon), tenosynovitis, -3.5 (p < 0.001), and osteitis, -1.3 (p < 0.05)] and at 12/24 months in synovitis and tenosynovitis [-1.6/-2.2 and -3.6/-3.8, respectively; all p < 0.001]. MRI signs of inflammation were not fully eliminated, and increases in erosion and JSN scores were observed at 6 months [0.4 (p < 0.01)/0.1 (p < 0.05)], 12 months [0.8 (p < 0.001)/0.3 (p < 0.01)], and 24 months [1.0 (p < 0.001)/0.4 (p < 0.001)]. Clinical measures decreased significantly (p < 0.001) at all time points. There were no consistent statistically significant differences between treatment groups. CONCLUSIONS: In this eRA treat-to-target trial, MTX and intra-articular glucocorticoids markedly reduced, but did not eliminate, MRI osteitis, synovitis, and tenosynovitis. Accordingly, minimal but statistically significant increases in bone erosion and JSN were observed. No additional effect of CyA was demonstrated.

RESUMEN

OBJECTIVES: To determine to what extent shared epitopes, smoking, and anti-cyclic citrullinated peptide (anti-CCP) antibodies are associated with disease activity and erosive disease in patients with rheumatoid arthritis (RA) at disease onset. METHOD: RA patients not previously treated with disease-modifying anti-rheumatic drugs (DMARDs) and with a disease duration of < 6 months (CIMESTRA study) were examined for shared epitopes, anti-CCP antibodies, immunoglobulin M rheumatoid factor (IgM-RF) and IgA-RF, radiographic erosive changes in hands and feet, and clinical disease activity. RESULTS: The study comprised 153 patients, of whom 104 (68%) were ever-smokers. The prevalence of patients with 0, 1, or 2 shared epitopes was 40 (48%), 71 (49%), and 33 (23%), respectively. Anti-CCP antibodies, IgM-RF, and IgA-RF were present in 89 (58%), 99 (65%), and 82 (54%) patients, respectively. Among smokers, erosive disease was associated with anti-CCP antibodies [odds ratio (OR) 3.9, 95% confidence interval (CI) 1.6-9.3], IgM-RF (OR 4.9, 95% CI 1.9-12), and IgA-RF (OR 2.8, 95% CI 1.2-6.4) but absent with regard to shared epitopes. Among never-smokers, erosive disease was not associated with either shared epitopes or antibodies. All antibody levels measured were associated with smoking and shared epitopes. CONCLUSIONS: Shared epitopes and smoking were associated with the production of anti-CCP antibodies and rheumatoid factors of IgM and IgA isotypes, which again were associated with erosive disease at presentation only in smokers. As shared epitopes and smoking were not directly associated with erosive disease, smoking may enhance the development of erosive disease in RA at different levels or through separate pathways.

RESUMEN

OBJECTIVES: The aim of this study was to measure, in early rheumatoid arthritis (RA) patients, the concentration of CC-chemokine ligand 19 (CCL19) in plasma and the cell-surface expression of CC-chemokine receptor 7 (CCR7) on circulating monocytes and CD4+ T lymphocytes and to analyse correlations with disease activity and 5-year radiographic progression. METHOD: In disease-modifying anti-rheumatic drug (DMARD)-naïve RA patients (disease duration < 6 months), we measured plasma CCL19 by enzyme-linked immunosorbent assay (ELISA) (n = 160) and CCR7 cell-surface expression on monocytes and CD4+ T lymphocytes by flow cytometry (n = 40) at baseline and after 1 year of treatment with methotrexate (MTX) or methotrexate+cyclosporin A (MTX/CyA). Radiographic progression was scored by the van der Heijde-modified Total Sharp Score (TSS) from 0 to 5 years. RESULTS: Increased baseline CCL19 (median 85 pg/mL, range 31-1008 pg/mL, p = 0.01) decreased after 1 year (median 31 pg/mL, range 31-1030 pg/mL, p < 0.001) and 5 years (median 31 pg/mL, range 31-247 pg/mL, p < 0.001) to a level below the controls (n = 45) (median 60 pg/mL, range 31-152 pg/mL). Baseline plasma CCL19 levels [p = 0.011, 95% confidence interval (CI) 0.0030-0.0176], anti-cyclic citrullinated peptide (anti-CCP) antibody status (p = 0.002, 95% CI 0.61-2.38), and TSS > 0 at baseline (p < 0.001, 95% CI 1.21-3.16) were independent predictors of 5-year radiographic progression evaluated by multiple logistic regression in contrast to never smoked, C-reactive protein (CRP), gender, age, number of tender (NTJ) and swollen joints (NSJ), and 28-joint Disease Activity Score (DAS28). Increased CCR7 expression on monocytes (p = 0.008) correlated to CRP (p = 0.006, r = 0.52) and normalized (n = 15) after 1 year (p = 0.02). CONCLUSIONS: In DMARD-naïve RA patients, CCL19 plasma level and CCR7 surface expression on monocytes were upregulated and normalized after 1 year of treatment. Increased baseline plasma CCL19 level, anti-CCP antibody status, and TSS > 0 at baseline correlated independently with 5-year radiographic progression.

RESUMEN

OBJECTIVES: The aims of this study were to investigate the influence of alendronate and intra-articular betamethasone treatment on bone mineral density (BMD) changes in hand, lumbar spine and femoral neck during 1 year of a treat-to-target study (Cyclosporine, Methotrexate, Steroid in RA (CIMESTRA)). PATIENTS AND METHODS: A hundred and sixty patients with early, active rheumatoid arthritis (RA) received methotrexate, intra-articular betamethasone and ciclosporin /placebo-ciclosporin. Patients with Z-score ≤0 also started alendronate 10 mg/day. BMD of the hand (digital x-ray radiogrammetry (DXR-BMDhand)), BMD of lumbar spine and femoral neck (dual x-ray absorptiometry (DXA-BMDlumbar spine and DXA-BMDfemoral neck)) and x-rays of hands, wrists and forefeet (modified Sharp-van der Heijde score) were measured at baseline and 1 year, with complete data available in 107 patients. RESULTS: The change in BMD in hand, lumbar spine and femoral neck was negatively associated with the dose of intra-articular betamethasone (p<0.01 for all), but the bone loss in hand was modest and in the axial skeleton comparable with that of healthy individuals. Alendronate did not influence changes in DXR-BMDhand, which averaged -2.8%, whereas significant changes were observed in DXA-BMDlumbar spine and DXA-BMDfemoral neck in alendronate-treated patients (1.8% and 0.8%) compared with untreated patients (-1.8% and -2.2%) (p<0.01 and 0.02). Alendronate did not affect the radiographic progression (alendronate-treated patients: 0 (range 0-19), non-alendronate: 0 (0-18)). CONCLUSIONS: In early active RA, intra-articular betamethasone injections added to disease-modifying antirheumatic drug (DMARD) treatment led to minimal loss of hip and lumbar BMD, and the loss could be prevented by treatment with alendronate. Alendronate treatment did not affect radiographic progression.

RESUMEN

Emerging research has provided support for the use of the Kessler Psychological Distress Scales in developing countries; however, this research has yet to be extended to southern Africa. This study sought to evaluate the performance of the Kessler scales in screening for depression and anxiety disorders in the South African population. The scales along with the Composite International Diagnostic Interview (CIDI) were included in the South African Stress and Health study, a nationally representative household survey. The K10/K6 demonstrated moderate discriminating ability in detecting depression and anxiety disorders in the general population; evidenced by area under the receiver operating curves of 0.73 and 0.72 respectively. However, both scales failed to meet our acceptability criteria of high sensitivity and high positive predictive value. Examinations of differences in responding by race/ethnicity revealed that the K10/K6 [Kessler Psychological Distress Scale 10-item (K10) and the abbreviated six-item (K6)] had significantly lower discriminating ability with respect to depression and anxiety disorders among the Black group (0.71) than among the combined minority race/ethnic groups of White, Colored, and Indian/Asian (0.78; p = 0.016). The difference in time period assessed on the K10/K6 (past 30 days) versus the CIDI (past 12 months) was a notable limitation of this study. Additional validation studies using clinician diagnostic instruments are recommended.

RESUMEN

OBJECTIVE: To identify predictors of radiographic progression in a 2-year randomised, double-blind, clinical study (CIMESTRA) of patients with early rheumatoid arthritis (RA). METHODS: Patients with early RA (n = 130) were treated with methotrexate, intra-articular betamethasone and ciclosporin/placebo-ciclosporin. Baseline magnetic resonance imaging (MRI) of the wrist (wrist-only group, n = 130) or MRI of wrist and metacarpophalangeal (MCP) joints (wrist+MCP group, n = 89) (OMERACT RAMRIS), x-ray examination of hands, wrists and forefeet (Sharp/van der Heijde Score (TSS)), Disease Activity Score (DAS28), anti-cyclic citrullinated peptide antibodies (anti-CCP), HLA-DRB1-shared epitope (SE) and smoking status were assessed. Multiple regression analysis was performed with delta-TSS (0-2 years) as dependent variable and baseline DAS28, TSS, MRI bone oedema score, MRI synovitis score, MRI erosion score, anti-CCP, smoking, SE, age and gender as explanatory variables. RESULTS: Baseline values: median DAS28 5.6 (range 2.4-8.0); anti-CCP positive 61%; radiographic erosions 56%. At 2 years: DAS28 2.0 (0.5-5.7), in DAS remission: 56%, radiographic progression 26% (wrist+MCP group, similar for wrist-only group). MRI bone oedema score was the only independent predictor of delta-TSS (wrist+MCP group: coefficient = 0.75 (95% CI 0.55 to 0.94), p<0.001; wrist-only group: coefficient = 0.59 (95% CI 0.40 to 0.77), p<0.001). Bone oedema score explained 41% of the variation in the progression of TSS (wrist+MCP group), 25% in wrist-only group (Pearson's r = 0.64 and r = 0.50, respectively). Results were confirmed by sensitivity analyses. CONCLUSION: In a randomised controlled trial aiming at remission in patients with early RA, baseline RAMRIS MRI bone oedema score of MCP and wrist joints (and of wrist only) was the strongest independent predictor of radiographic progression in hands, wrists and forefeet after 2 years. MRI synovitis score, MRI erosion score, DAS28, anti-CCP, SE, smoking, age and gender were not independent risk factors. TRIAL REGISTRATION NUMBER: NCT00209859.

RESUMEN

OBJECTIVE: To investigate whether clinical and radiographic disease control can be achieved and maintained in patients with early, active rheumatoid arthritis (RA) during the second year of aggressive treatment with conventional disease-modifying antirheumatic drugs (DMARDs) and intra-articular corticosteroid. This paper presents the results of the second year of the randomised, controlled double-blind CIMESTRA (Ciclosporine, Methotrexate, Steroid in RA) study. METHODS: 160 patients with early RA (duration <6 months) were randomised to receive intra-articular betamethasone in any swollen joint in combination with step-up treatment with either methotrexate and placebo-ciclosporine (monotherapy) or methotrexate plus ciclosporine (combination therapy) during the first 76 weeks. At week 68 hydroxychlorochine 200 mg daily was added. From week 76-104 ciclosporine/placebo-ciclosporine was tapered to zero. RESULTS: American College of Rheumatology 20% improvement (ACR20), ACR50 and ACR70 levels were achieved in 88%, 79% and 59% of patients in the combination vs 72%, 62% and 54% in the monotherapy group (p = 0.03, 0.02 and 0.6 between groups). The patients globally declined from 50 to 12 vs 52 to 9, with 51% and 50% in Disease Activity Score (DAS) remission, respectively. Mean (SD) progressions in total Sharp-van der Heijde scores were 1.42 (3.52) and 2.03 (5.86) in combination and monotherapy groups, respectively (not significant). Serum creatinine levels increased by 7% in the combination group (4% in monotherapy), but hypertension was not more prevalent. CONCLUSION: Continuous methotrexate and intra-articular corticosteroid treatment resulted in excellent clinical response and disease control at 2 years, and the radiographic erosive progression was minimal. Addition of ciclosporine during the first 76 weeks resulted in significantly better ACR20 and ACR50 responses, but did not have any additional effect on remission rate and radiographic outcome.

RESUMEN

OBJECTIVE: To present from the Danish Database for Biological Therapies in Rheumatology (DANBIO) the frequencies and types of adverse events as well as risk factors during treatment with biological agents in clinical practice. METHODS: Adverse events during the first 2 years of clinical use of biological agents in Denmark were reported to the nationwide DANBIO and compared to the mandatory reports to the Danish Medicines Agency. RESULTS: Almost 90% of the patients treated with biological agents were registered in the DANBIO, and the database picked up 20 times as many adverse events as the Danish Medicines Agency. Infections and hypersensitivity reactions were the most prevalent adverse events. Age, disease duration, and previous number of disease-modifying anti-rheumatic drugs (DMARDS) were found to be risk factors for bacterial infections. CONCLUSION: A routine-based Danish database for biological therapies covers approximately 90% of patients and improves the reporting of adverse events.

RESUMEN

Medicare coverage of ambulance services is a topic that receives little attention in educational materials but is a major source of confusion for people with Medicare, their families and professionals. In this brief we discuss and clarify coverage issues and payment policies for ambulance services, including the potential costs for consumers. We conclude with a look at situations where appeals of denial of payment for these services may be appropriate.

RESUMEN

Joint erosion is a prevalent feature of rheumatoid arthritis (RA) but not of many other chronic inflammatory arthritides (non-RA). Joint destruction is mediated by cytokines, primarily interleukin (IL)-1 and tumour necrosis factor. Less erosive activity in patients with non-RA compared to RA might be related to factors that inhibit production and/or function of IL-1. Release of IL-1beta, and the two antagonists, IL-1 receptor antagonist (IL-1ra) and IL-10 from blood mononuclear cells were therefore quantitated by ELISA in 22 patients with RA, 11 with non-RA and 15 healthy age-matched controls. Release of IL-1beta was comparable between the three groups but only detectable in cultures stimulated with lipopolysaccharide; it decreased in patients treated with prednisolone: 3.8 ng/10(6)monocytes (median) vs 11.7 (P=0.045). Release of IL-1ra was in all but IgG-stimulated cultures comparable between groups. The ratio of IL-1ra/IL-1beta was elevated in LPS-stimulated cells from RA patients only: 2.0 versus 1.3 (P=0.02). In contrast, IgG-induced IL-1ra release was significantly elevated only in non-RA patients: 95 ng/10(6)monocytes vs 40 (P=0.014), and the levels correlated positively to those of blood CRP (P=0.02). Though stimulated release of IL-10 was similar between the three groups, the levels were lower in non-erosive than erosive arthritis patients, and controls (P=0. 05). In conclusion, increased IgG-stimulated IL-1ra release and elevated IL-1ra/IL-1beta ratio may protect against actions of IL-1 in vivo, and decreased release of IL-10 might be related to features of non-erosive arthritis.

RESUMEN

Depositions of immune-complexes are responsible for many of the pathological features of systemic lupus erythematosus (SLE). For example, immune-complex-induced tissue damage in glomerulonephritis has been shown to be mediated, at least in part, by interleukin (IL)-1. Inappropriate production or function of IL-1 may therefore contribute to disease manifestations in SLE. We investigated lipopolysaccharide (LPS)- and adherent IgG-stimulated release of IL-1beta, IL-1 receptor antagonist (IL-1ra) and IL-10, a potent modulator of IL-1, by blood mononuclear cells from patients with SLE. Mediator production was measured as ng cytokines/10(6) monocytes and compared with clinical parameters. Release of IL-1beta was only detectable in LPS-stimulated cultures and substantially reduced in patients with both active and inactive disease (P < 0.001). LPS-stimulated IL-1ra release was normal and the IL-1ra/IL-1beta ratio was therefore increased (P < 0.05) and correlated inversely to prednisolone dosage (P = 0.009). IgG-stimulated release of IL-1ra was reduced in patients with active disease compared to those with inactive disease and controls (P = 0.002). IL-10 release was similar in patients and controls. We conclude that monocytes from patients with active SLE are deficient in Fc gamma-R-mediated production of IL-1ra, whereas LPS-stimulated IL-1beta release by SLE monocytes is reduced regardless of disease activity. The former may contribute to immune-complex-mediated tissue damage in SLE.

RESUMEN

The aim of this investigation was to examine the deaths of drug addicts from poisoning in the county of Funen in 1995 and 1996. The cause of death was related to drugs on the illicit market. Social conditions (homelessness, involvement in crime, psychogenic disease, circumstance of death) are discussed. The study included 47 drug addicts. Median age was 34, age span: 20-43. The main cause of death was poisoning by heroin. In 28% of the drug addicts cocaine was detected and in 13% amphetamine. About half had used benzodiazepines. Few were employees, most were criminals and eight were homeless. Thirty-eight percent were found in public lavatories. Eight had a serious psychiatric diagnosis. We can conclude that the drug addicts are socially marginalized. They abused a mixture of drugs. The drugs detected in the drug addicts compared well with the drugs on the illicit market and cocaine had gained access to the market.

RESUMEN

OBJECTIVE: To investigate whether red cell folate (RCF) levels relate to side effects, withdrawals, or disease activity during treatment with the folic acid antagonist methotrexate (MTX) for rheumatoid arthritis (RA). METHODS: Side effects were recorded monthly, RCF levels were measured by lactoglobulin binding radioassays, and 8 variables for disease activity were measured in a placebo controlled double blind trial of 28 weeks' duration comparing efficacy of MTX (n = 23) and D-penicillamine (n = 23). RESULTS: From Week 20 RCF levels decreased only in the MTX group (p < 0.02), and 5 MTX treated patients withdrew due to side effects. Withdrawals had lower RCF values at Weeks 0 and 9 compared to the remaining patients (p < 0.05). Folate deficiency evolved in 5 patients; 2 of these developed cytopenia. Aberrations in the scheduled dosage increase were related to lower pretreatment values of RCF (p = 0.007). Side effect scores were inversely correlated to RCF values at Weeks 0, 9, and 28 (p < 0.05). RCF levels measured concomitantly with liver enzyme elevation were lower than the remaining values (p < 0.001). When side effects were reported, 96% of concomitantly measured RCF values were below 800 nmol/l. RCF values at entry did not correlate to improvement in any variable for disease activity, or a graded overall improvement. CONCLUSION: RCF levels decrease during MTX treatment and relate to side effects, withdrawals, liver enzyme elevations and aberrant MTX dosage increase, but not to the therapeutic effect. RCF above 800 nmol/l protects against side effects.

RESUMEN

OBJECTIVE: To assess the efficacy and safety of sulphasalazine in reactive arthritis. METHODS: Double blind placebo controlled trial of six months duration comparing sulphasalazine 2-3 g per day (n = 37) with matching placebo (n = 42) in adults with active reactive arthritis (age 19-57 years, median 34). Treatment response was evaluated once a month by changes in erythrocyte sedimentation rate (ESR), pain, peripheral arthritis, tender iliosacral joints, entesopathy, extra-articular manifestations, and working ability. RESULTS: 15 patients in the sulphasalazine group and eight in the placebo group withdrew from the study prematurely. Adverse events, primarily gastrointestinal, were the main reason for withdrawal in the actively treated group. Intention-to-treat analyses showed significant improvements over time in both groups in ESR, pain, and number of swollen joints (P < 0.01). Number of days on sick leave decreased significantly in the sulphasalazine group only (P < 0.01). No significant differences between the two groups were present after six months. Among the patients completing the trial according to protocol, persistent complete remission had occurred within two months in five (23%) of the actively treated, but in no placebo treated patients (P = 0.013). CONCLUSIONS: Sulphasalazine seemed to improve only the very short term outcome of reactive arthritis. The possible beneficial effect of the drug should also be weighed against the risk of adverse events. Although these were mainly mild, almost 25% of the patients in the actively treated group gave up treatment for this reason.
