RESUMO

We report a multidrug-resistant Neisseria gonorrhoeae exhibiting resistance to ceftriaxone and cefixime, isolated in Portugal in 2019. Whole-genome sequencing was performed for typing and identification of genetic determinants of antimicrobial resistance. Because of its antimicrobial susceptibility profile, awareness should be raised for the circulation of this strain.

RESUMO

Systemic lupus erythematosus (SLE) is a multisystemic autoimmune disorder which may affect the gastrointestinal system. Half of the patients with SLE experience gastrointestinal symptoms, with the most common being nausea, vomiting, anorexia, and abdominal pain. Mesenteric vasculitis is a severe and rare complication of SLE and one of the most frequent causes of severe acute abdominal pain. The authors present a case of a 57-year-old woman with SLE who was diagnosed with necrotizing mesenteric vasculitis following a urinary septic shock. The patient was treated with high-dose corticosteroid therapy and cyclophosphamide, with resolution of the clinical picture.

RESUMO

OBJECTIVE: To develop evidence-based recommendations for the non-pharmacological and pharmacological management of Raynaud's phenomenon (RP) and digital ulcers (DUs) in patients with systemic sclerosis and other immune-mediated connective tissue diseases (CTDs). METHODS: A task force comprising 21 rheumatologists, two surgeons (vascular and plastic), two nurses, and one patient representative was established. Following a systematic literature review performed to inform the recommendations, statements were formulated and discussed during two meetings (one online and one in-person). Levels of evidence, grades of recommendation (GoR), and level of agreement (LoA) were determined. RESULTS: Five overarching principles and 13 recommendations were developed. GoR ranged from A to D. The mean ± standard difference (SD) LoA with the overarching principles and recommendations ranged from 7.8±2.1 to 9.8±0.4. Briefly, the management of RP and DUs in patients with CTDs should be coordinated by a multidisciplinary team and based on shared decisions with patients. Nifedipine should be used as first-line therapy for RP and/or DUs. Sildenafil, tadalafil, and/or iloprost IV are second-line options for severe and/or refractory patients with RP and/or DUs. Sildenafil, tadalafil and/or Iloprost IV, should be prescribed for healing and prevention (also including bosentan) of DUs. In patients with RP and/or DUs, non-pharmacological interventions might be considered as add-ons, but there is limited quality and quantity of scientific evidence supporting their use. CONCLUSIONS: These recommendations will inform rheumatologists, specialist nurses, other healthcare professionals, and patients about a comprehensive and personalized management of RP and DUs. A research agenda was developed to address unmet needs, particularly for non-pharmacologic interventions.

RESUMO

Introduction: HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with late presentation in the MSM population newly diagnosed with HIV in Portugal between 2014 and 2019. Methods: We included 391 newly HIV-1 diagnosed Men who have Sex with Men (MSM), from the BESTHOPE project, in 17 countrywide Portuguese hospitals. The data included clinical and socio-behavioral questionnaires and the viral genomic sequence obtained in the drug resistance test before starting antiretrovirals (ARVs). HIV-1 subtypes and epidemiological surveillance mutations were determined using different bioinformatics tools. Logistic regression was used to estimate the association between predictor variables and late presentation (LP). Results: The median age was 31 years, 51% had a current income between 501-1,000 euros, 28% were migrants. 21% had never been tested for HIV before diagnosis, with 42.3% of MSM presenting LP. 60% were infected with subtype B strains. In the multivariate regression, increased age at diagnosis, higher income, lower frequency of screening, STI ever diagnosed and higher viral load were associated with LP. Conclusion: Our study suggests that specific subgroups of the MSM population, such older MSM, with higher income and lower HIV testing frequency, are not being targeted by community and clinical screening services. Overall, targeted public health measures should be strengthened toward these subgroups, through strengthened primary care testing, expanded access to PrEP, information and promotion of HIV self-testing and more inclusive and accessible health services.

RESUMO

A woman with systemic sclerosis presents with a severe and rapidly progressive form of gastrointestinal involvement, mainly marked by recurrent refractory episodes of pseudo-obstruction, culminating in severe malnutrition and dependence of parenteral nutrition. The impact on her quality of life was extremely significant. As a last resort, she started intravenous immunoglobulin with progressive improvement of her symptoms, allowing for the reinstitution of oral diet and removal of parenteral nutrition. After more than 1 year, she maintains clinical stability. Systemic sclerosis has a heterogeneous phenotype, but gastrointestinal involvement is one of the most frequent. Severe manifestations are rare, but can lead to severe malnutrition and are associated with high morbidity and mortality rates. Their management is challenging, as the available treatments are still very limited. A better understanding of its pathophysiology, which seems to be unique, is essential to provide more effective treatments and improving quality of life.

RESUMO

Arthritis in the paediatric population is the hallmark of many rheumatic inflammatory diseases, as well as other cutaneous, infectious, or neoplastic conditions. It can be quite devastating, whereby prompt recognition and treatment of these disorders are essential. However, arthritis can sometimes be mistaken for other cutaneous or genetic conditions leading to misdiagnosis and overtreatment. Pachydermodactyly is a rare and benign form of digital fibromatosis, usually manifested by swelling of the proximal interphalangeal joints of both hands, mimicking arthritis. The authors report a case of a 12-year-old boy with a one-year history of painless swelling of the proximal interphalangeal joints of both hands that was referred to the Paediatric Rheumatology department due to the suspicion of juvenile idiopathic arthritis. The diagnostic work-up was unremarkable, and the patient remained asymptomatic over an 18-month follow-up period. A diagnosis of pachydermodactyly was assumed and no treatment was introduced, given the benign nature of the disorder and absence of symptoms. Therefore, it was possible to safely discharge the patient from the Paediatric Rheumatology clinic.

RESUMO

Hypereosinophilia is unusual in rheumatoid arthritis (RA), but can occur in severe long-lasting disease, especially in patients with extra-articular manifestations and high titers of rheumatoid factor (RF). The association of RA and hypereosinophilic syndrome (HES) remains yet poorly known. We present a case of a 46 years old woman with long-standing untreated RA, that presented to emergency department with severe symptoms of constrictive pericarditis with cardiac tamponade and bilateral pleural effusion, that progressed to cardiac arrest, associated to symmetrical polyarthritis and pruritic erythematous skin papules. She was submitted to urgent pericardial drainage and partial pericardiotomy. Laboratory analyses revealed hypereosinophilia, and elevated inflammatory parameters and immunoglobulin E. The histological study of the pericardium showed results consistent with inflammatory fibrinous pericarditis. Taking into account the presence of some characteristics that are usually present in cases of reactive HES instead of idiopathic HES, and after an intensive diagnostic study, that could rule out other potential causes of secondary HES, the diagnosis of HES associated with RA was made. She started glucocorticoids during hospitalization and methotrexate 15mg per week at the first outpatient rheumatology visit. After 12 weeks of treatment, we considered that she was in clinical and analytical remission, consistently maintaining that after a complete tapering of glucocorticoids. This case illustrates that clinicians should be aware that HES (including severe life-threatening cases) can occur in patients with RA, especially in cases of long-lasting disease with high titters of RF and without treatment, even in the absence of extra-articular features.

RESUMO

BACKGROUND: Hepatitis B virus (HBV) vaccination is recommended for non-immunised patients with rheumatic diseases starting biological disease-modifying antirheumatic drugs (bDMARDs). There is some evidence that HBV vaccination is effective in patients under conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), but it is currently unclear whether this also applies to bDMARDs. OBJECTIVES: To assess the efficacy and safety of HBV vaccination in patients with inflammatory arthritides treated with bDMARDs. METHODS: A prospective cohort with inflammatory arthritides treated with bDMARDs, negative for anti-HBs and anti-HBc and never vaccinated for HBV was recruited. Engerix B was administered at 0, 1 and 6 months and anti-HBs was reassessed ≥1 month after last dose. Response was defined as anti-HBs≥10 IU/L and compared against vaccinated healthy controls. Disease flare, serious adverse events and immune-related disorders not previously present were recorded. RESULTS: 62 patients, most treated with TNF inhibitors (TNFi), and 38 controls were recruited. Most patients were taking csDMARDs (67.7%) and were in remission/low disease activity (59.4%). Only 20/62 patients (32.3%) had a positive response to vaccination, in comparison to 36/38 age-matched controls (94.7%, p<0.001). Response was seen in 19/51 patients treated with TNFi (37.3%) and in 1/11 (9.1%) patients treated with non-TNFi (p=0.07), including 1/6 treated with tocilizumab (16.7%). Among TNFi, response rates ranged from 4/22 (18.2%) for infliximab to 8/14 (57.1%) for etanercept. No relevant safety issues were identified. CONCLUSIONS: HBV vaccination response in patients with rheumatic diseases treated with bDMARDs was poorer than expected. Our data reinforce the recommendation for vaccination prior to starting bDMARDs.

RESUMO

Mycobacterium marinum is a non-tuberculous mycobacteria present in natural and non-chlorinated bodies of water. It is a known fish pathogen but can also cause human disease. It usually causes cutaneous lesions but in rare cases may originate more invasive diseases with the involvement of deep structures. We describe three cases of patients with cutaneous infection by M. marinum evaluated in a tertiary care center, two with confirmed infection and one with a presumptive diagnosis based on clinical and epidemiological features. A brief bibliographic review of M. marinum infections is then presented to support the theme. We aim to alert one to the difficulties in establishing the correct diagnosis of this infection, emphasize the importance of a high degree of suspicion for its identification, and review the therapeutic management options.

RESUMO

Objective: To describe and analyze transmitted drug resistance (TDR) between 2014 and 2019 in newly infected patients with HIV-1 in Portugal and to characterize its transmission networks. Methods: Clinical, socioepidemiological, and risk behavior data were collected from 820 newly diagnosed patients in Portugal between September 2014 and December 2019. The sequences obtained from drug resistance testing were used for subtyping, TDR determination, and transmission cluster (TC) analyses. Results: In Portugal, the overall prevalence of TDR between 2014 and 2019 was 11.0%. TDR presented a decreasing trend from 16.7% in 2014 to 9.2% in 2016 (p for-trend = 0.114). Multivariate analysis indicated that TDR was significantly associated with transmission route (MSM presented a lower probability of presenting TDR when compared to heterosexual contact) and with subtype (subtype C presented significantly more TDR when compared to subtype B). TC analysis corroborated that the heterosexual risk group presented a higher proportion of TDR in TCs when compared to MSMs. Among subtype A1, TDR reached 16.6% in heterosexuals, followed by 14.2% in patients infected with subtype B and 9.4% in patients infected with subtype G. Conclusion: Our molecular epidemiology approach indicates that the HIV-1 epidemic in Portugal is changing among risk group populations, with heterosexuals showing increasing levels of HIV-1 transmission and TDR. Prevention measures for this subpopulation should be reinforced.

RESUMO

We propose a guideline about the risk, prevention and treatment of infection in the patient under immunomodulatory or immunosuppressive therapy in the context of autoimmune or autoinflammatory disease. It is divided into three sections: drugs and associated risk of infection; immunizations; risk, prevention, and treatment of specific infections. The treatment of autoimmune diseases involves the use of immunosuppressive or immunomodulatory therapies, with an increasing number of new drugs being used. It is associated with an increased risk of infection, which may be present globally or only for specific agents, varying widely depending on the pharmacological class and even within the same class. The prevention strategy and clinical management need to be individually tailored and there are several key factors: characterization of the disease that prompts the immunosuppression, understanding of the mechanism of action of the immunosuppressive drug, knowledge of previous infections, recognition of risk factors, laboratory test results, vaccine administration, monitoring of clinical signs and symptoms and patient education.


O presente protocolo aborda o risco, prevenção e tratamento da infeção no doente sob terapêutica imunomoduladora ou imunossupressoraem contexto de doença autoimune ou autoinflamatória. Subdivide-se nas seguintes secções: fármacos e risco associado de infeção; imunizações; risco, prevenção e tratamento de infeções específicas. Com um número crescente de novos fármacos em utilização nos últimos anos, o tratamento de doenças autoimunes envolve a utilização de terapêuticas imunossupressoras ou imunomoduladoras e associa-se a aumento do risco de infeção, que pode estar presente de uma forma global ou apenas para infeções por agentes específicos, variando amplamente consoante a classe farmacológica e mesmo dentro desta. Na estruturação da estratégia preventiva são fundamentais a caracterização da patologia que motiva a imunossupressão, a compreensão do mecanismo de ação do imunossupressor, a aferição de infeções prévias, o reconhecimento de fatores de risco, a realização de rastreios laboratoriais, a administração de vacinas, a educação do doente e a monitorização de sintomas e sinais clínicos, na dependência de uma gestão clínica necessariamente individualizada.

RESUMO

CD4+ T cells mediate rheumatoid arthritis (RA) pathogenesis through both antibody-dependent and independent mechanisms. It remains unclear how synovial microenvironment impinges on CD4+ T cells pathogenic functions. Here, we identified a TLR4+ follicular helper T (Tfh) cell-like population present in the blood and expanded in synovial fluid. TLR4+ T cells possess a two-pronged pathogenic activity whereby direct TLR4+ engagement by endogenous ligands in the arthritic joint reprograms them from an IL-21 response, known to sponsor antibody production towards an IL-17 inflammatory program recognized to fuel tissue damage. Ex vivo, synovial fluid TLR4+ T cells produced IL-17, but not IL-21. Blocking TLR4 signaling with a specific inhibitor impaired IL-17 production in response to synovial fluid recognition. Mechanistically, we unveiled that T-cell HLA-DR regulates their TLR4 expression. TLR4+ T cells appear to uniquely reconcile an ability to promote systemic antibody production with a local synovial driven tissue damage program.

RESUMO

Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis is an autoimmune disorder, seen most often in young adults and children, triggered by tumors or infections. We report a case of cryptococcal meningitis in a patient with sarcoidosis, presenting prominent neuropsychiatric symptoms, electroencephalographic features of autoimmune encephalitis and positive anti-NMDAR antibodies in the cerebrospinal fluid, raising the hypothesis of an infectious immune-mediated mechanism triggering the production of anti-NMDAR antibodies. Since anti-NMDAR encephalitis is potentially fatal and has significant morbidity, further descriptions of its etiological associations are essential to early identification and prompt treatment.

RESUMO

BACKGROUND: The information associated with loss to follow-up (LFU) patients may affect real-world data evaluation of the use of biologics that is not being adequately captured in registries. METHODS: We identified all patients (Pts) treated with biologics in our center who had no visits registered for more than 6 months, in the Rheumatic Diseases Portuguese Register, Reuma.pt. We retrieved baseline information from Reuma.pt and from the hospital electronic clinical record. We then performed a telephonic interview to characterize the reasons for LFU at our day care unit. For Pts unable to be contacted by telephone a letter of invitation to an appointment at the hospital was sent. RESULTS: From a total of 794 Pts registered in Reuma.pt at our center with active biologic therapy 227 did not have any information registered in the last 6 months. Of this, 36 Pts were on biologic therapy prescribed by other departments and maintained follow-up in these departments. 102 Pts had suspended biologic administration by medical indication and this information was registered in the hospital electronic clinical records but not updated in Reuma.pt. For 89 Pts no information could be retrieved from either the hospital electronic clinical record or Reuma.pt and we classified these Pts as true LFU. 26 of these LFU Pts were being followed up in another Rheumatology center. 26 of the LFU Pts died. 11 Pts had an adverse effect. 4 Pts of the LFU were considering to be in remission. We were not able to contact 15 of the LFU pts. CONCLUSION: Identifying LFU Pts and clarifying the reason for the loss of data in a register contributes to a better knowledge on strategies to discontinue biologics in stable pts, to a better pharmacovigilance of adverse effects and to more efficiency in data capture by registries. Due to data protection reasons it was impossible to have access to the Pts's death certificates.

RESUMO

Telehealth applied to rheumatology, known as telerheumatology, is an emerging trend in healthcare in many countries. It constitutes a promising approach with the potential to anticipate the contact of patients from remote areas with Rheumatologists, leading to earlier diagnosis and treatment, and thus probably to better long-term outcomes. Telerheumatology under the scope of International collaborations may also improve the access of the PALOP population to Rheumatology care, resulting in proper shared decisions for patient's evacuation, preventing family separation and reducing the costs associated to intercontinental dislocations.
