RESUMO
Neuropathies secondary to tophus compression in gout patients are well known; however, limited data exist on other types of peripheral neuropathies (PN). Our aim was to describe PN frequency, characteristics, distribution, patterns, and associated factors in gout patients through clinical evaluation, a PN questionnaire, and nerve conduction studies (NCS). This cross-sectional descriptive study included consecutive gout patients (ACR/EULAR 2015 criteria) from our clinic. All underwent evaluation by Rheumatology and Rehabilitation departments, with IRB approval. Based on NCS, patients were categorized as PN + (presence) or PN- (absence). PN + patients were further classified as local peripheral neuropathy (LPN) or generalized somatic peripheral neuropathy (GPN). We enrolled 162 patients, 98% male (72% tophaceous gout). Mean age (SD): 49.4 (12) years; mean BMI: 27.9 (6.0) kg/m2. Comorbidities included dyslipidemia (53%), hypertension (28%), and obesity (23.5%). Abnormal NCS: 65% (n = 106); 52% LPN, 48% GPN. PN + patients were older, had lower education, and severe tophaceous gout. GPN patients were older, had lower education, and higher DN4 scores compared to LPN or PN- groups (p = 0.05); other risk factors were not significant. Over half of gout patients experienced neuropathy, with 48% having multiplex mononeuropathy or polyneuropathy. This was associated with joint damage and functional impairment. Mechanisms and risk factors remain unclear. Early recognition and management are crucial for optimizing clinical outcomes and quality of life in these patients. Key Points Peripheral neuropathies in gout patients had been scarcely reported and studied. This paper report that: ⢠PN in gout is more frequent and more diverse than previously reported. ⢠Mononeuropathies are frequent, median but also ulnar, peroneal and tibial nerves could be injured. ⢠Unexpected, generalized neuropathies (polyneuropathy and multiplex mononeuropathy) are frequent and associated to severe gout. ⢠The direct role of hyperuricemia /or gout in peripheral nerves require further studies.

INTRODUCTION: Gout is the most common inflammatory arthritis, but was not considered in most COVID-19 and rheumatic diseases reports. Our aim was to describe changes in clinical data, treatment, function and quality of life for gout patients during COVID-19 pandemic. METHODS: Prospective, descriptive and analytical study of 101 consecutive gout (ACR/EULAR 2015) patients from our clinic evaluated during pandemic by phone call (n=52) or phone call + face-to-face (n=68) that accepted to participate. Variables are demographics, clinical and treatment data, HAQ, EQ5D questionnaires and COVID-19-related data. Patients were divided in two groups: flare (n=36) or intercritical gout (n=65) also; available pre-pandemic data was obtained from 71 patients. Statistical analyses are X2, paired t-test and Wilcoxon test. RESULTS: Included gout patients were males (95.8%), mean (SD) age 54.7 (10.7) years and disease duration 16.4 (9.8) years; 90% received allopurinol, 50% colchicine as prophylaxis and 25% suspended ≥ 1 medication. Comparison of pre-pandemic vs pandemic data showed > flares (4.4% vs 36%, p=0.01), more flares in the last 6 months: 0.31 (0.75) vs 1.71 (3.1), (p=0.004 and > urate levels: 5.6 (1.7)vs 6.7 (2.2) mg/dL, p=0.016. Unexpectedly, function and quality-of-life scores improved: HAQ score 0.65 (2.16) vs 0.12 (0.17), p= 0.001. Seven patients were COVID-19-confirmed cases; they had significantly more flares, higher urate levels and lower allopurinol doses and two died. CONCLUSIONS: In gout patients, flares were 9 times more frequent during pandemic also, they had increased urate levels but led to an unexpected improvement in HAQ and functionality scores. Resilience and lifestyle changes in gout during COVID-19 pandemic require further studies. Key Points ⢠COVID-19 pandemic is associated with 4 times more flares in gout patients. ⢠Increased flares were also seen in previously well-controlled gout patients. ⢠Increased serum urate levels were also found in gout patients during pandemic. ⢠In our gout clinic, 8/101 patients were diagnosed as COVID-19+, and two of them died.

Objective: To compare the assessment of entheses in subjects with spondyloarthritis (SpA) with patients with gout by the Madrid Sonographic Enthesis Index (MASEI). Method: This cross-sectional study includes videos of entheses evaluated by ultrasound (US) of 30 patients with SpA diagnosed according to the ASAS criteria and 30 patients with gout established by the presence of monosodium urate crystals. Entheses were evaluated for MASEI in 2 Institutes located in two different countries. Demographic and clinical data were registered. Total MASEI score, MASEI-inflammatory, and MASEI-chronic damage were analyzed. Comparisons between groups were obtained by chi-square test and Student's t-test. An inter-reading US reliability was realized. Results: Patients with gout were older and had significantly more comorbidities than those with SpA. The total MASEI score was not significantly different among diseases (p = 0.07). MASEI-inflammatory was significantly more prevalent at the Achilles tendon in SpA, while the proximal patellar tendon was in gout. Power Doppler was higher in SpA compared to gout (p = 0.005). MASEI-chronic damage related to calcification/enthesophytes predominated in gout (p = 0.043), while calcaneal erosions did in SpA (p = 0.008). The inter-reader concordance was excellent (0.93, CI 95% 0.87-0.96, p = 0.001). Conclusions: SpA and gout similarly involve entheses according to MASE, however, some inflammatory and chronic lesions differ significantly depending on the underlying disease and tendon scanned.
RESUMO
OBJECTIVES: To update the recommendations for the management of patients with Spondyloarthritis (SpA) in the Mexican population, and identify which variables could influence patient management. MATERIAL AND METHODS: A group of 15 experts in SpA translated, analyzed and modified the recommendations of the Mexican College of Rheumatology (CMR) and the International Society for the Assessment of Spondyloarthritis (ASAS)/European League Against Rheumatism (EULAR) 2016 group through a systematic review of the literature by two external reviewers during the period from 2015 to 2018 using the grade of recommendation, Oxford levels of evidence, percentage of concordance (Delphi). RESULTS: Compared to previous recommendations, there were no significant changes from the year 2015. However, we modified the five fundamental principles and reduced the number of recommendations to ten by incorporating the first item in the text and combining five recommendations into two and adding a further recommendation. We confirmed the tendency to use glucocorticoids for patients with inflammatory activity and scarce access to biologicals. We identified the sociodemographic and clinical characteristics of patients with SpA and their influence on the application of the recommendations. CONCLUSIONS: The ten recommendations of the CMR and the analysis of the characteristics of the Mexican patients with SpA focussed on step therapy, including pharmacological and non-pharmacological therapies, in a spectrum from easily accessible to high-tech substances available to a small percentage of the population.
RESUMO
OBJECTIVE: Determine the proportion of patients achieving target serum urate (SU), defined as < 6 mg/dl for patients with non-severe gout and < 5 mg/dl for patients with severe gout, as well as the proportion of patients achieving remission after 5 years of followup. METHODS: Patients from the Gout Study Group (GRESGO) cohort were evaluated at 6-month intervals. Demographic and clinical data were obtained at baseline. Visits included assessments of serum urate, flares, tophus burden, health-related quality of life using the EQ-5D, activity limitations using the Health Assessment Questionnaire adapted for gout, and pain level and patient's global assessment using visual analog scales. Treatment for gout and associated diseases was prescribed according to guidelines and available drugs. RESULTS: Of 500 patients studied, 221 had severe gout (44%) and 279 had non-severe gout (56%) at baseline. No significant differences were observed across the study in percentages of severe gout versus non-severe gout patients achieving SU 6 mg/dl or 5 mg/dl. The highest proportion of patients achieving target SU (50-70%) and remission (39%) were found after 3-4 years of followup. In the fifth year, these proportions decreased and 28% of the patients were in remission, but only 40 patients remained in the study. None of the patients with severe gout achieved remission. CONCLUSION: In patients with severe gout, target SU was hard to achieve and remission was not possible. The main obstacles for target SU and gout remission include poor medication adherence, persistent tophi, and loss to followup.

Objetivos: Actualizar las recomendaciones para el manejo de pacientes con espondiloartritis (EspA) en la población mexicana e identificar las variables que podrían influir en el manejo del paciente. Material y métodos: Un grupo de 15 expertos en EspA tradujo, analizó y modificó las recomendaciones del Colegio Mexicano de Reumatología (CMR) y del grupo Sociedad Internacional de Evaluación de las Espondiloartritis (ASAS)/Liga Europea contra el Reumatismo (EULAR) del 2016 a través de la revisión sistemática de la literatura realizada por dos revisores externos en el período de 2015 a 2018 utilizando los niveles de GRADE y Oxford y el porcentaje de concordancia (Delphi). Resultados: En comparación con las recomendaciones anteriores, no hubo cambios significativos desde el año 2015. Sin embargo, modificamos los 5 principios fundamentales y reducimos el número de recomendaciones a 10 por la incorporación de la primera en el texto, la combinación de 5 recomendaciones en 2 y la adición de una nueva. Confirmamos la tendencia del uso de glucocorticoides para pacientes con actividad inflamatoria y escaso acceso a productos biológicos. Se identificaron las características sociodemográficas y clínicas de los pacientes con EspA y su posible influencia en la aplicación de las recomendaciones. Conclusiones: Las 10 recomendaciones del CMR y el análisis de las características de los pacientes mexicanos con EspA se centran en el tratamiento escalonado con medios farmacológicos y no farmacológicos, fácilmente accesibles, o por el contrario sustancias de alta tecnología para un pequeño porcentaje de la población.(AU)
