RESUMO

INTRODUCTION:  Diffuse alveolar hemorrhage (DAH) is a rare complication with high mortality in patients with systemic lupus erythematosus (SLE). Early diagnosis and treatment are essential to improve patient prognosis. To determine the characteristics of patients with DAH and their mortality in a Spanish cohort of patients with SLE. METHODS:  Patients from the RELESSER (Spanish Society of Rheumatology Lupus Register) who had had at least one confirmed episode of DAH were included. Epidemiological, clinical, and laboratory characteristics were analyzed. RESULTS:  4024 patients were included in the RELESSER register, 37 (0.9%), had at least one recorded episode of DAH. Only further data for 14 patients could be analyzed. In total, 92.9% were women, and for 4 (28.6%) DAH coincided with the debut of SLE. More than 80% of patients had renal involvement and thrombocytopenia. The most frequent manifestations were dyspnea (85.7%) and hypoxemia (100%), with the classic triad of hemoptysis, anemia and pulmonary infiltrates, appearing in 6 (46.2%) patients. The most frequently used treatments were glucocorticoids (85.7%) and cyclophosphamide (69.2%); plasmapheresis was utilized in 5 patients (35.7%) and 8, (57.1%) received intravenous immunoglobulins; 12 (85.7%) patients required admission to the ICU and 5 (35.7%) died. Tobacco use, history of lupus nephritis (LN), concomitant infection, and treatment with cyclophosphamide were more frequent in patients who died. CONCLUSIONS:  DAH is rare in patients with SLE; in up to one-third of patients, it may appear at the onset of the disease. Some factors, such as smoking, a history of LN, treatment with cyclophosphamide, or concomitant infection, are more prevalent in patients with an unfavorable outcome.

RESUMO

Psoriatic disease (PsD) affects multiple clinical domains and causes a significant inflammatory burden in patients, requiring comprehensive evaluation and treatment. In recent years, new molecules such as JAK inhibitors (JAKinhibs) have been developed. These have very clear advantages: they act quickly, have a beneficial effect on pain, are well tolerated and the administration route is oral. Despite all this, there is still little scientific evidence in daily clinical practice. This observational, retrospective, single-center study was carried out in patients diagnosed with PsA in the last two years, who started treatment with Tofacitinib or Upadacitinib due to failure of a DMARD. The data of 32 patients were analyzed, and the majority of them (75%) started treatment with Tofacitinib. Most had moderate arthritis activity and mild psoriasis involvement according to activity indices. Both Tofacitinib and Upadacitinib demonstrated significant efficacy, with rapid and statistically significant improvement in joint and skin activity indices, C-reactive protein reduction, and objective measures of disease activity such as the number of painful and inflamed joints. Although there was some difference in the baseline characteristics of the cohort, treatment responses were comparable or even superior to those in the pivotal clinical trials. In addition, there was a low frequency of mild adverse events leading to treatment discontinuation and no serious adverse events. These findings emphasize the strong efficacy and tolerability of JAKinhibs in daily clinical practice, supporting their role as effective therapeutic options for patients with PsD.

RESUMO

Toxoplasmosis continues to be a prevalent parasitic zoonosis with a global distribution. This disease is caused by an intracellular parasite known as Toxoplasma gondii, and the development of effective novel drug targets to combat it is imperative. There is limited information available on the potential advantages of wheat germ oil (WGO) and propolis, both individually and in combination, against the acute phase of toxoplasmosis. In this study, acute toxoplasmosis was induced in Swiss albino mice, followed by the treatment of infected animals with WGO and propolis, either separately or in combination. After 10 days of experimental infection and treatment, mice from all groups were sacrificed, and their brains, uteri, and kidneys were excised for histopathological assessment. Additionally, the average parasite load in the brain was determined through parasitological assessment, and quantification of the parasite was performed using Real-Time Polymerase Chain Reaction targeting gene amplification. Remarkably, the study found that treating infected animals with wheat germ oil and propolis significantly reduced the parasite load compared to the control group that was infected but not treated. Moreover, the group treated with a combination of wheat germ oil and propolis exhibited a markedly greater reduction in parasitic load compared to the other groups. Similarly, the combination treatment effectively restored the histopathological changes observed in the brain, uterus, and kidney, and the scoring of these reported lesions confirmed these findings. In summary, the present results reveal intriguing insights into the potential therapeutic benefits of wheat germ oil and propolis in the treatment of acute toxoplasmosis.

RESUMO

BACKGROUND: Biological therapies against tumor necrosis factor α have revolutionized the treatment of several inflammatory rheumatic diseases. However, 30% of responders will present a clinical failure after having controlled the disease for at least 6 months (secondary clinical failure). Biological therapies may induce an unwanted immune response, which may alter the bioavailability of the drug causing a loss of clinical response. OBJECTIVE: The objective of this study was to assess the correlation between secondary clinical failure (based on Disease Activity Score in 28 Joints or Bath Ankylosing Spondylitis Disease Activity Index) and the type of mechanism involved in failure (based on drug levels) in patients with inflammatory arthropathies treated with anti-tumor necrosis factor α. METHODS: Drug and antidrug antibodies (ADAs) serum levels were determined by enzyme-linked immunosorbent assay immediately before drug administration in patients with rheumatoid arthritis, ankylosing spondylitis, and psoriatic arthritis who presented secondary clinical failure after at least 6 months of treatment with adalimumab (ADL) or etanercept (ETN). RESULTS: Thirty-six patients with secondary clinical failure were recruited: 63.88% had rheumatoid arthritis, 22.22% had psoriatic arthritis, and 13.88% had ankylosing spondylitis; 58.33% did not respond to ADL, whereas 41.66% did not to ETN. None of the patients treated with ETN showed either subtherapeutic drugs levels or ADAs (failure due to a primary mechanism) whereas it was found that 23.80% of the patients treated with ADL had subtherapeutic drug levels for reasons attributable to immunogenicity (failure due to a secondary mechanism; P = 0.000048). CONCLUSIONS: We suggest the utility of measuring drug and ADA levels in patients with secondary clinical failure to ADL for a better optimization and rational use, but not in patients who fail to ETN.

RESUMO

OBJECTIVE: To assess cardiovascular (CV) risk in psoriatic arthritis (PsA) patients without clinically evident CV disease or classic atherosclerosis risk factors according to the SCORE chart following the EULAR recommendations. METHODS: Eighty PsA patients without previous CV events or atherosclerosis risk factors and eighty matched controls were included. Information on demographic, anthropometric and clinical-serological data of disease was assessed. The national calibrated Systematic Coronary Risk Evaluation (SCORE) index was calculated and the association between this SCORE and clinical-serological data of these patients was analyzed. RESULTS: PsA patients had higher acute phase reactants as well as higher SCORE mean values than healthy controls (1.99±3.52 vs. 1.0±1.74; P=0.028). According to SCORE definitions, 71 (89%) patients had low-intermediate CV risk and 9 (11%) were above the threshold of high risk. In the control group, 76 (95%) had low-intermediate risk and four (5%) had high CV risk. However, there were no differences in CV risk stratification between both groups (P=0.148). PsA patients with high-very high CV risk had longer disease duration (P=0.001) and higher levels of triglycerides (P=0.009). PsA patients showed a significant correlation between SCORE values and disease duration (ß=0.185; P=0.0001) and the average annual levels of C reactive protein (CRPa), ß=2.38; P=0.014. CONCLUSION: CV risk assessment in PsA patients without clinically evident CV disease or classic atherosclerosis risk factors may be underestimated by using only the SCORE chart. In these patients, disease duration and the CRPa may help to establish a better stratification of the actual CV risk.

RESUMO

BACKGROUND: Psoriasis has been related to a higher prevalence of cardiovascular risk factors. Vitamin-D deficiency has been associated with metabolic syndrome, cardiovascular disease, and psoriasis. However, there has been no comparative study on the effects of vitamin-D status between patients with and without psoriatic arthritis. OBJECTIVE: The objective was to assess the relationship of 25-hydroxyvitamin D [25-(OH)D] levels with lipid and glucose metabolism parameters in psoriatic patients with and without arthritis. METHODS: We studied 122 patients with psoriasis (61 without arthritis and 61 with arthritis) from the psoriasis unit (dermatology department) and rheumatology department of our hospital, analyzing lipid and glucose metabolism variables and serum 25-(OH)D concentrations. Measurements were conducted within a 2-month period to minimize seasonal bias in 25-(OH)D levels. RESULTS: In the psoriatic patients without arthritis, serum 25-(OH)D levels were inversely correlated with fasting glucose (r = -0.285; P = .026), total cholesterol (r = -0.440; P = .000), low-density lipoprotein (r = -0.415; P = .001), total cholesterol/high-density lipoprotein (r = -0.303; P = .01), and triglyceride (r = -0.280; P = .029) values. This association remained statistically significant for glucose, total cholesterol, and low-density lipoprotein after controlling for confounding factors in multivariate analysis. No association was found between serum 25-(OH)D levels and any metabolic parameter in the patients with psoriatic arthritis. LIMITATIONS: This is a cross-sectional study that supports the hypothesis of an association between vitamin D and metabolic parameters but does not establish a causal relationship. CONCLUSIONS: Serum 25-(OH)D was inversely related to lipid and glucose metabolism parameters in psoriatic patients without arthritis, whereas no such association was observed in psoriatic patients with arthritis. Interventional studies are warranted to assess the effects of vitamin-D supplements on the metabolic profile of psoriatic patients without arthritis.

RESUMO

Behçet's disease (BD) is a chronic, complex multisystem vasculitis of unknown cause characterised for its ability to involve blood vessels of all sizes on both the arterial and venous sides of the circulation. It has been suggested that TNF-alpha plays a main role in the pathogenesis of BD. This hypothesis is supported by the efficacy of TNF-blocking antibodies in these patients, which have been shown to be very powerful in the induction of remission and as maintenance treatment on different BD manifestations, including severe vascular involvement. However, little is known about when and how to stop IFX after long-standing complete remission of these patients to avoid relapses. We describe a case of BD without previous vascular involvement that developed myocardial infarction and severe venous thromboses only four months after discontinuation of infliximab (IFX) after more than three years of complete remission. The patient did not respond to corticosteroids and intravenous cyclophosphamide and only recovered completely after reintroducing IFX.

RESUMO

AA (secondary) amyloidosis is one of the most severe and uncommon complications of several rheumatic disorders and chronic infections such as tuberculosis (TB). Successful treatment depends on the control of the underlying inflammatory process, what can lead to an improvement or a regression in organ dysfunction. If the disorder persists, it has been reported in some cases of AA amyloidosis secondary to rheumatic diseases, that the use of biologic therapy is so far the only opportunity to reduce the development of AA amyloidosis and to reverse established deposits. We report herein a case of a latent TB infection complicated by a life-threatening AA amyloidosis presented as nephrotic syndrome. After an adequate antituberculostatic treatment, AA amyloidosis remained active and Tocilizumab (TCZ) was started with a dramatic resolution of the proteinuria, stabilization of the amyloid deposits and improvement in general condition.

RESUMO

INTRODUCTION: The aim of this pilot study was to evaluate the initial response to 16 weeks of treatment with infliximab and etanercept of disease activity and quality of life in a cohort of 37 patients with established rheumatoid arthritis. PATIENTS AND METHOD: Patients were selected from the Unit of Rheumatology in Hospital Clínico San Cecilio from Granada, refractory to conventional treatment with disease modifying antirheumatic drugs. To assess the disease activity, Disease activity score (DAS28) was used and the measurement of quality of life was evaluated with the Spanish version of the SF-36 Health Survey (SF-36) and the RA-specific questionnaire QoL Scale (Quality of Life in Rheumatoid Arthritis). RESULTS: Preliminary results show a significant decrease in inflammatory activity of the disease and consequently in HRQL scores. The comparison with the general reference population shows a deviation well below average, especially in the "physical function" dimension with a rising response pattern in all dimensions. The correlation between specific scores (QoL-RA scale) and generic ones (SF-36) for HQ-treatment also showed significance, especially with the physical aggregate. DISCUSSION: An important limitation of the present study is the number of patients and the duration of the treatment; despite this, improvements in functional parameters and quality of life are evident and remain roughly stable since the first weeks of treatment. This allow us to continue the study and increase the number of patients. CONCLUSIONS: The preliminary results obtained with TNF-blockers after 16 weeks of treatment in RA objectively show the effectiveness of these drugs and also the perception by the patients of the effect on their quality of life.

RESUMO

BACKGROUND AND OBJECTIVE: High parathyroid hormone (PTH) concentrations are associated with increased bone resorption and bone matrix degradation. Some studies show elevated PTH concentrations and hypocalcemia in patients with advanced prostate carcinoma, although the pathophysiological significance of these findings is not well defined. MATERIALS AND METHODS: We performed a retrospective study of 60 patients diagnosed with advanced prostate cancer (44 nonmetastatic and 16 metastatic) treated with androgen deprivation. In all patients, PTH, calcium, phosphorus, 25 (OH) vitamin D and prostate-specific antigen (PSA) were determined. Bone scintigraphy had previously been performed. RESULTS: In patients with bone metastases, mean concentrations were as follows: calcium 9.19 mg/dl, phosphorus 3.47 mg/dl, 25 (OH) vitamin D 13.85 ng/ml, PTH 66.8 pg/ml and total PSA 101.27 ng/ml. For those without bone metastases, the results were calcium 9.39 mg/dl, phosphorus 3.38 mg/dl, 25 (OH) vitamin D 20.50 ng/ml, PTH 52.23 pg/ml and total PSA 2.52 ng/ml. PTH levels were significantly higher in patients with prostate cancer and bone metastases than in those without metastases (p=0.03). Vitamin D levels were also significantly lower in this group (p=0.03). There were no differences in other values. CONCLUSIONS: The present study found increased PTH concentrations in patients with advanced prostate cancer. This finding could be useful to predict disease progression.

RESUMO

In the present study plasma samples from 15 systemic lupus erythematosus (SLE) patients and 16 healthy controls of initially unknown haptoglobin (Hp) phenotype were separated by 2-DE, and tryptic digests of the excised Hpalpha polypeptide chain spots were analyzed by MALDI-TOF-MS. Selected tryptic peptides were sequenced by nano-(n)ESI-IT MS/MS. The six major Hp phenotypes were present, although with distinct frequencies in controls and SLE patients. Thus, there were an increased proportion of SLE patients with Hp 2-2, or Hp 2-1S phenotypes. The Hp phenotype distribution resulted in allele frequencies of 0 625 (Hp(2)), 0.281 (Hp(1S)), and 0.093 (Hp(1F)) in healthy controls, correlating fairly well with the allele frequencies of European populations. In contrast, the Hp allele frequencies of the SLE patients were 0.733 (Hp(2)), 0.233 (Hp(1S)), and 0.033 (Hp1(1F)), which clearly indicated an increased frequency of Hp(2), a similar proportion of Hp(1S) and a diminished proportion of Hp(1F) in SLE patients compared with that in healthy controls. Preferential Hpalpha2 expression in SLE patients may contribute to some of the clinical manifestations of the disease such as hypergammaglobulinemia, systemic vasculitis, and cardiovascular disorders.

RESUMO

In this study we have determined whether there is a relationship between CD38 expression on T cells, its distribution in different membrane microdomains, and T cell activation in SLE patients. The data show that CD38 expression is augmented in ex vivo CD3+, CD4+, CD8+, and CD25+ SLE T cells, which correlates with its increased insolubility in Brij 98 detergent, and its translocation into lipid rafts. Moreover, SLE T cells show an altered CD4:CD8 ratio, which is due to a decreased proportion of CD4+ T cells and a concomitant increase in the proportion of CD8+ T cells. These data are consistent with the increased CD38 expression and lipid raft formation, and the significant reduction in the CD4:CD8 ratio observed in mitogen-stimulated normal T cells as compared with that in ex vivo untouched normal T cells. Increased expression of CD38 in floating rafts from SLE T cells, or from activated normal T cells may modulate TCR signaling by providing or sequestering signaling molecules to the engaged TCR.
