- Absolute Hyperglycemia versus Stress Hyperglycemia Ratio for the Prognosis of Hospitalized Patients with COVID-19 in the First Months of the Pandemic: A Retrospective StudyPublication . Matias, AA; Manique, I; Sabino, T; Rego, T; Mihon, C; Panarra, A; Rizzo, M; Silva-Nunes, JDiabetes is a risk factor for greater severity of coronavirus disease 2019 (COVID-19). The stress hyperglycemia ratio (SHR) is an independent predictor of critical illness, and it is reported to have a stronger association than absolute hyperglycemia. The aim of this study was to assess the relationship of absolute hyperglycemia and SHR with the severity of COVID-19, since there are no studies investigating SHR in patients with COVID-19. We conducted a retrospective observational study on hospitalized patients with COVID-19 in the first months of the pandemic, regarding absolute hyperglycemia, SHR, and severity outcomes. Of the 374 patients, 28.1% had a previous diagnosis of type 2 diabetes. Absolute hyperglycemia (64.8% versus 22.7%; p < 0.01) and SHR [1.1 (IQR 0.9-1.3) versus 1.0 (IQR 0.9-1.2); p < 0.001] showed a statistically significant association with previous diabetes. Absolute hyperglycemia showed a significant association with clinical severity of COVID-19 (79.0% versus 62.7%; p < 0.001), need for oxygen therapy (74.8% versus 54.4%; p < 0.001), invasive mechanical ventilation (28.6% versus 11.6%; p < 0.001), and intensive care unit (30.3% versus 14.9%; p = 0.002), but not with mortality; by contrast, there was no statistically significant association between SHR and all these parameters. Our results are in agreement with the literature regarding the impact of absolute hyperglycemia on COVID-19 severity outcomes, while SHR was not a significant marker. We therefore suggest that SHR should not be evaluated in all patients admitted in the hospital for COVID-19, and we encourage the standard measures at admission of blood glucose and HbA1c levels.
- Actinobacillus Endocarditis Associated with Hypertrophic CardiomyopathyPublication . Jorge, VC; Araújo, AC; Grilo, A; Noronha, C; Panarra, A; Riso, N; Vaz Riscado, MInfective endocarditis can be associated with complex clinical presentations, sometimes with a difficult multi-disciplinary management. Actinobacillus actinomycetemcomitans belongs to the Haemophilus species, Actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens and Kingella species group, responsible for 5% to 10% of infective endocarditis in native heart valves. These organisms have slow fastidious growth pattern, often associated with negative cultures, and cause systemic embolism with abscess formation. The authors present the case of a 59-year-old man, admitted due to fever of unknown origin, with a personal history of obstructive hypertrophic cardiomyopathy and recent dental manipulation. The diagnosis of mitral valve's endocarditis was established after a transoesophageal ecocardiography, with a late isolation of A actinomycetemcomitans in blood culture. Despite the institution of antibiotic therapy, the patient suffered from multiple episodes of septic embolism: skin, mucosae, cerebral abscesses, spondylodiscitis and uveitis. He was submitted to heart surgery with miectomy and replacement of the native mitral valve by a mechanical prosthesis, while on antibiotics.
- Antiphospholipid Syndrome and Recurrent Thrombosis--Limitations of Current Treatment StrategiesPublication . Coelho Henriques, C; Lourenço, F; Lopéz, B; Panarra, A; Riso, NAntiphospholipid syndrome (APS) is a systemic autoimmune disorder that is characterised by the presence of antiphospholipid antibodies and a common cause of vascular thromboembolic phenomena. The management of patients with APS is currently directed to antithrombotic medications. The international therapeutic guidelines recommend oral anticoagulation with warfarin indefinitely after the first thrombotic episode. However, therapeutic guidelines lack for a minority group of patients - the patients appropriately anticoagulated with recurrent thromboembolic phenomena. The authors present a clinical report that reveals the therapeutic and diagnostic complexity of this specific group of patients. Regarding recent studies, APS has been revealed as a complex syndrome with multiple pathophysiological mechanisms previously unknown. In this context, new therapeutic approaches have been defended and empirically experienced, with potentially promising results.
- Buerger's Disease (Thromboangiitis Obliterans): a Diagnostic ChallengePublication . Jorge, VC; Araújo, AC; Noronha, C; Panarra, A; Riso, N; Vaz Riscado, MBuerger's disease or Thromboangiitis obliterans is a segmental inflammatory disease that affects the vessels and nerves of the extremities. It usually affects men below 45 years old and correlates with tobacco, as a predisposing factor. The authors present the case of a 34-year-old male, with ulcers in the fingertips with progressive worsening: acrocyanosis, slow healing, necrosis and finally loss of substance. Dorsalis pedis and posterior tibial pulses were not palpable. Personal history of heavy smoking was (20 pack-years). The angiography revealed proximal occlusion of the left posterior tibial and interosseal arteries, with distal circulation by the anterior tibial artery. He was submitted to disarticulation of the second left toe and therapy with pentoxifyline and iloprost infusion, calcium antagonist, antiplatelet drugs, statin and low molecular weight heparin (later replaced by oral anticoagulation). Improvement was seen of active vascular lesions and pain symptoms.

- Clinical Presentation and Long-Term Outcomes of Systemic Sclerosis Portuguese Patients from a Single Centre Cohort: A EUSTAR Registration InitiativePublication . Vidal, C; Ruano, C; Bernardino, V; Lavado Carreira, P; Lladó, A; Santos, MC; Gruner, H; Panarra, A; Riso, N; Moraes-Fontes, MFINTRODUCTION: Systemic sclerosis is a complex disorder that requires systematic screening. Our objective is to report the European Scleroderma Trials and Research group centre affiliation and its impact in our clinical practice. MATERIAL AND METHODS: The European Scleroderma Trials and Research group affiliation process, database update and current patient evaluation, with respect to demographic and clinical features. Cumulative mortality was analysed. RESULTS: We identified 19 female patients (which met all the American College of Rheumatology/ European League Against Rheumatism 2013 criteria for systemic sclerosis) under current follow-up, divided according to the LeRoy classification into diffuse cutaneous (n = 5), limited cutaneous (n = 11) and limited (n = 3) types, followed for a median period of 5, 12 and 6 years, respectively. Raynaud´s phenomenon and abnormal nailfold capillaries were universally present. Interstitial lung disease was absent in the limited cutaneous form but present in 100% of the diffuse subtype. Pitting scars were more common in the diffuse form. Active disease was also more frequent in the diffuse form, and most patients with active disease were treated with anti-endothelin receptor antagonists. Over 21 years (from 1994 to 2015) the mortality rate was 55% (n = 23/42). Age at time of death was significantly lower in the diffuse subtype. DISCUSSION: Our single centre cohort shares many features with larger and international reports and more specifically is in accordance with patient characteristics described in the European Scleroderma Trials and Research group registries. CONCLUSION: The European Scleroderma Trials and Research group registration motivated our systematic patient characterization and may be used as a tool for homogenous disease registries.
- Implementing an Influenza Vaccine Effectiveness Study in a Hospital Context in Portugal: The EVA Hospital ProjectPublication . Machado, A; Gomez, V; Panarra, A; Poças, J; Corte-Real, R; Peres, MJ; Nunes, BIntroduction: The project ‘Integrated Monitoring of Vaccines in Europe’ aimed to measure seasonal influenza vaccine effectiveness against hospitalised adults, aged 65 years and over, with influenza. We describe the protocol implementation in Portugal. Material and Methods: We implemented a test-negative design, targeting community-dwelling patients aged 65 years old and over hospitalised with severe acute respiratory illness. Patients were reverse transverse-polymerase chain reaction tested for influenza. Cases were those positive for influenza while others were controls. Most variables were collected using hospital medical records. Selection bias was evaluated by comparison with the laboratory influenza test requests database according to demographic characteristics. Crude, season-adjusted influenza vaccine effectiveness was estimated as = 1 – odds ratio, and 95% confidence intervals were obtained by conditional logistical regression, matched with the disease onset month. Results: The recruitment rate was 37.8%. Most participants (n = 368) were female (55.8%) and aged 80 years old and over (55.8%). This was similar to values for potentially eligible severe acute respiratory illness patients (80 years old and over: 56.8%, female: 56.2%). The proportion of missing values was below 2.5% for 20 variables and above 5% (maximum 11.6%) for six variables. Influenza vaccine effectiveness estimates were 62.1% against AH1pdm09 (95% confidence intervals: -28.1 to 88.8), 14.9% against A(H3N2) (95% confidence intervals: -69.6 to 57.3), 43.6% against B/Yam (95% confidence intervals: -66.2 to 80.8). Discussion: Given the non-existence of a coded admission database in either participating hospital the selection of severe acute respiratory illness due to clinical features was the feasible one. These results are only valid for the older adult population residing in the catchment area of the two participating hospitals who were admitted to a public hospital with severe influenza or SARI symptoms. Conclusion: Despite the low participation rate, we observed comparable characteristics of participants and eligible severe acute respiratory illness patients. Data quality was high, and influenza vaccine effectiveness results were in accordance with the results of meta-analyses and European season-specific estimates. The final sample size was low, which inhibited obtaining estimates with good precision.

- Leprosy and Rheumatoid Arthritis: Consequence or Association?Publication . Coelho Henriques, C; Lopéz, B; Mestre, T; Grima, B; Panarra, A; Riso, NLeprosy or Hansen's disease is a chronic granulomatous infectious disease caused by Mycobacterium leprae with a high prevalence in some developing countries however, it is rarely seen in non-endemic regions. Arthritis has been described in all types of Hansen's disease. Chronic arthritis is known to exist even in paucibacillary forms, resolved or treated disease and in patients without reaction, suggesting a perpetuated inflammatory process. In these cases leprosy can mimic some autoimmune diseases such as rheumatoid arthritis. When a patient with a history of leprosy presents with a symmetric, distal, polyarthritis the diagnosis may not be linear. Possibly it is a rheumatoid-like leprous arthritis with M leprae acting as the trigger element for the chronic process or it is an overlap condition, with a concomitant rheumatoid arthritis? A case report of a patient with a chronic inflammatory arthritis with 10 years of evolution is presented. The differential diagnosis between leprous and rheumatoid arthritis is discussed.
