RESUMO

Introducción: Los pacientes con artritis reumatoide pueden desarrollar enfermedad tiroidea autoinmune (ETA), cuyo diagnóstico clínico puede ser difícil debido a que ambas comparten síntomas como artralgias, mialgias, rigidez matutina o fatiga. Objetivo: Determinar la prevalencia de ETA en pacientes con artritis reumatoide. Método: Estudio transversal que incluyó 78 pacientes con artritis reumatoide y 81 controles clínicamente sanos pareados por edad y sexo. A ambos grupos se realizó cuantificación de anticuerpos antitiroideos, pruebas de función tiroidea, ultrasonido y biopsia de glándula tiroides cuando la puntuación de Thyroid Imaging Reporting and Data System (TIRADS) fue ≥ 4. Resultados: 24.4 % de los pacientes con artritis reumatoide presentó hipotiroidismo (p = 0.003) y altos títulos de anticuerpos antitiroideos versus controles clínicamente sanos; 53 % de los ultrasonidos tiroideos resultó normal en pacientes hipotiroideos; en pacientes con artritis reumatoide positivos para anticuerpos antitiroideos se encontró perfusión incrementada en 40 %. Los casos clasificados como TIRADS 4 fueron enviados a aspiración, con resultado histopatológico benigno. Conclusiones: Se demostró el valor clínico agregado de la evaluación tiroidea en pacientes con artritis reumatoide, conforme a la prevalencia de hipotiroidismo subclínico, positividad de anticuerpos antitiroideos y anomalías en el ultrasonido independientes de la función tiroidea normal o alterada. Introduction: Patients with rheumatoid arthritis can develop autoimmune thyroid disease (ATD), the clinical diagnosis of which can be difficult because both entities share symptoms such as arthralgia, myalgia, morning stiffness or fatigue. Objective: To determine the prevalence of ATD in patients with rheumatoid arthritis. Method: Cross-sectional study that included 78 patients with rheumatoid arthritis and 81 clinically healthy controls matched by age and gender. Both groups underwent anti-thyroid antibodies quantification, thyroid function tests, thyroid ultrasound and thyroid gland biopsy when the Thyroid Imaging Reporting and Data System (TIRADS) score was ≥ 4. Results: Hypothyroidism was found in 24.4% of patients with rheumatoid arthritis (p = 0.003), as well as high titers of anti-thyroid antibodies versus clinically healthy controls; 53% of thyroid ultrasounds were normal in hypothyroid patients, and increased perfusion was found in 40% of rheumatoid arthritis patients who tested positive for anti-thyroid antibodies. Cases classified as TIRADS 4 underwent aspiration with benign histopathological results. Conclusions: Thyroid assessment added clinical value was demonstrated in patients with rheumatoid arthritis, according to the prevalence of subclinical hypothyroidism, anti-thyroid antibodies positivity and ultrasound abnormalities, regardless of normal or altered thyroid function.

RESUMO

Splanchnic vein thrombosis is an unusual manifestation of venous thromboembolism and includes portal vein thrombosis, mesenteric veins thrombosis, splenic vein thrombosis, and the Budd-Chiari syndrome. The most common risk factors include hematologic and autoimmune disorders, hormonal therapy, liver cirrhosis, solid abdominal cancer, recent abdominal surgery, and abdominal infections or inflammatory conditions, such as pancreatitis. Splanchnic vein thrombosis in acute pancreatitis is most commonly associated with the severe form of the disease and pancreatic necrosis. This report describes a case of splanchnic vein thrombosis as a complication of necrotizing acute pancreatitis in a pediatric patient. Splanchnic vein thrombosis was incidentally detected on contrast-enhanced computed tomography to assess the pancreas. There was no evidence of prior risk factors for the thrombotic condition. The patient was treated with anticoagulation and showed complete resolution after recovery from necrotizing acute pancreatitis, at a 16-month follow-up. The complication of necrotizing acute pancreatitis with splanchnic vein thrombosis in pediatric age is a rare presentation.

RESUMO

Acute disseminated encephalomyelitis (ADEM) has been linked to immunizations, viral infections, and occasionally to arthropods stings. Its association with scorpion stings has not been described. A 29-year-old man, who after being stung by a scorpion presented right hemiparesis and language impairment. Brain MRI showed subcortical bihemispheric lesion characteristics of ADEM and a bigger one compatible with Baló concentric sclerosis (BCS). Patient was managed with steroids, showing complete clinical improvement. Magnetic resonance imaging (MRI) after 6 months showed cavitation of the bigger lesion with no new findings. In 2 years of follow-up, there is no clinical relapse or new lesions in MRI. Although cases of ADEM have been reported due to venom of chilopoda and hymenoptera, the scorpion sting can be considered as another new cause; this case being even more relevant due to present a Baló-like lesion in MRI.

RESUMO

Gallstone ileus is a mechanical intestinal obstruction due to gallstone impaction within the gastrointestinal tract. Less than 1% of cases of intestinal obstruction are derived from this etiology. The symptoms and signs of gallstone ileus are mostly nonspecific. This entity has been observed with a higher frequency among the elderly, the majority of which have concomitant medical illness. Cardiovascular, pulmonary, and metabolic diseases should be considered as they may affect the prognosis. Surgical relief of gastrointestinal obstruction remains the mainstay of operative treatment. The current surgical procedures are: (1) simple enterolithotomy; (2) enterolithotomy, cholecystectomy and fistula closure (one-stage procedure); and (3) enterolithotomy with cholecystectomy performed later (two-stage procedure). Bowel resection is necessary in certain cases after enterolithotomy is performed. Large prospective laparoscopic and endoscopic trials are expected.

RESUMO

UNLABELLED: The main cause of death in rheumatoid arthritis (RA) is cardiovascular events. We evaluated the relationship of anticyclic citrullinated peptide (anti-CCP) antibody levels with increased carotid intima-media thickness (cIMT) in RA patients. METHODS: Forty-five anti-CCP positive and 37 anti-CCP negative RA patients, and 62 healthy controls (HC) were studied. All groups were assessed for atherogenic index of plasma (AIP) and cIMT. Anti-CCP, C-reactive protein (CRP), and levels of tumor necrosis factor alpha (TNFα) and interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS: The anti-CCP positive RA patients showed increased cIMT compared to HC and anti-CCP negative (P < 0.001). Anti-CCP positive versus anti-CCP negative RA patients, had increased AIP, TNFα and IL-6 (P < 0.01), and lower levels of high density lipoprotein cholesterol (HDL-c) (P = 0.02). The cIMT correlated with levels of anti-CCP (r = 0.513, P = 0.001), CRP (r = 0.799, P < 0.001), TNFα (r = 0.642, P = 0.001), and IL-6 (r = 0.751, P < 0.001). In multiple regression analysis, cIMT was associated with CRP (P < 0.001) and anti-CCP levels (P = 0.03). CONCLUSIONS: Levels of anti-CCP and CRP are associated with increased cIMT and cardiovascular risk supporting a clinical role of the measurement of cIMT in RA in predicting and preventing cardiovascular events.

RESUMO

UNLABELLED: Patients with rheumatoid arthritis (RA) have a higher risk for atherosclerosis. There is no clinical information about scavenger receptor CD36 and the development of subclinical atherosclerosis in patients with RA. The aim of this study was to evaluate the association between membrane expression of CD36 in peripheral blood mononuclear cells (PBMC) and carotid intima-media thickness (cIMT) in patients with RA. METHODS: We included 67 patients with RA from the Rheumatology Department of Hospital Civil "Dr. Juan I. Menchaca," Guadalajara, Jalisco, Mexico. We evaluated the cIMT, considering subclinical atherosclerosis when >0.6 mm. Since our main objective was to associate the membrane expression of CD36 with subclinical atherosclerosis, other molecules related with cardiovascular risk such as ox-LDL, IL-6, and TNFα were tested. RESULTS: We found low CD36 membrane expression in PBMC from RA patients with subclinical atherosclerosis (P < 0.001). CD36 mean fluorescence intensity had negative correlations with cIMT (r = -0.578, P < 0.001), ox-LDL (r = -0.427, P = 0.05), TNFα (r = -0.729, P < 0.001), and IL-6 (r = -0.822, P < 0.001). CONCLUSION: RA patients with subclinical atherosclerosis showed low membrane expression of CD36 in PBMC and increased serum proinflammatory cytokines. Further studies are needed to clarify the regulation of CD36 in RA.
