Colchicine for prevention of postpericardiotomy syndrome and postoperative atrial fibrillation : the COPPS-2 randomized clinical trial

IMPORTANCE: Postpericardiotomy syndrome, postoperative atrial fibrillation (AF), and postoperative effusions may be responsible for increased morbidity and health care costs after cardiac surgery. Postoperative use of colchicine prevented these complications in a single trial. OBJECTIVE: To determine the efficacy and safety of perioperative use of oral colchicine in reducing postpericardiotomy syndrome, postoperative AF, and postoperative pericardial or pleural effusions. DESIGN, SETTING, AND PARTICIPANTS: Investigator-initiated, double-blind, placebo-controlled, randomized clinical trial among 360 consecutive candidates for cardiac surgery enrolled in 11 Italian centers between March 2012 and March 2014. At enrollment, mean age of the trial participants was 67.5 years (SD, 10.6 years), 69% were men, and 36% had planned valvular surgery. Main exclusion criteria were absence of sinus rhythm at enrollment, cardiac transplantation, and contraindications to colchicine. INTERVENTIONS: Patients were randomized to receive placebo (n=180) or colchicine (0.5 mg twice daily in patients 6570 kg or 0.5 mg once daily in patients <70 kg; n=180) starting between 48 and 72 hours before surgery and continued for 1 month after surgery. MAIN OUTCOMES AND MEASURES: Occurrence of postpericardiotomy syndrome within 3 months; main secondary study end points were postoperative AF and pericardial or pleural effusion. RESULTS: The primary end point of postpericardiotomy syndrome occurred in 35 patients (19.4%) assigned to colchicine and in 53 (29.4%) assigned to placebo (absolute difference, 10.0%; 95% CI, 1.1%-18.7%; number needed to treat\u2009=\u200910). There were no significant differences between the colchicine and placebo groups for the secondary end points of postoperative AF (colchicine, 61 patients [33.9%]; placebo, 75 patients [41.7%]; absolute difference, 7.8%; 95% CI, -2.2% to 17.6%) or postoperative pericardial/pleural effusion (colchicine, 103 patients [57.2%]; placebo, 106 patients [58.9%]; absolute difference, 1.7%; 95% CI, -8.5% to 11.7%), although there was a reduction in postoperative AF in the prespecified on-treatment analysis (placebo, 61/148 patients [41.2%]; colchicine, 38/141 patients [27.0%]; absolute difference, 14.2%; 95% CI, 3.3%-24.7%). Adverse events occurred in 21 patients (11.7%) in the placebo group vs 36 (20.0%) in the colchicine group (absolute difference, 8.3%; 95% CI; 0.76%-15.9%; number needed to harm\u2009=\u200912), but discontinuation rates were similar. No serious adverse events were observed. CONCLUSIONS AND RELEVANCE: Among patients undergoing cardiac surgery, perioperative use of colchicine compared with placebo reduced the incidence of postpericardiotomy syndrome but not of postoperative AF or postoperative pericardial/pleural effusion. The increased risk of gastrointestinal adverse effects reduced the potential benefits of colchicine in this setting. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT0155218

Clinical management and therapy of idiopathic recurrent pericarditis

Recurrent pericarditis is defined when pericarditic chest pain reappears after a symptom-free period of at least 4 to 6 weeks and after completion of full-dose anti-inflammatory therapy. Idiopathic pericarditis is the commonest etiology. The diagnosis of idiopathic cases is essentially an exclusion diagnosis, supported by a typical clinical course. The diagnosis is based on the association of typical symptoms and signs: mainly pericarditic chest pain plus pericardial rubs or electrocardiographic alterations or pericardial effusion. The optimal regimen for recurrences includes combination of non-steroidal anti-inflammatory agents, colchicine, and corticosteroids. In the resistant forms, immunotherapy (azathioprine, intravenous immunoglobulins, and particularly anakinra) has shown to be effective. The long term outcome of idiopathic recurrent pericarditis is good, with no evolution towards constrictive form

Outcome of Patients Surgically Treated for Various Forms of Hyperthyroidism with Differentiated Thyroid Cancer: Experience at an Endocrine Center in Italy.

PURPOSE: The incidence and aggressiveness of thyroid cancer associated with hyperthyroidism remains a subject of much controversy. The aim of this study was to analyze the frequency of coexisting hyperthyroidism and thyroid cancer, and to determine whether cancer becomes more aggressive with different forms of hyperthyroidism. METHODS: We retrospectively studied 2,449 patients assessed for hyperthyroidism between 1985 and 2001. All patients with a "cold" nodule on scintigraphy, such as those with Graves' disease and a concomitant solid nodule, underwent fine-needle aspiration biopsy (FNAB). Criteria for surgery were cytological findings indicative of malignancy, goiter with signs of tracheal or esophageal compression, side effects of antithyroid drug therapy, or Graves' disease with multiple relapses after therapy withdrawal or responsiveness to antithyroid drugs. RESULTS: Thyroid cancer was diagnosed more frequently in patients with Graves' disease (6.5%) than in those with uninodular toxic goiter (UTG) (4.4%) or multinodular toxic goiter (MTG) (3.9%). Lymph node involvement was found in 56% of the patients with Graves' disease, in 23% of those with MTG, and in none of those with UTG. Distant metastases were found in one patient with Graves' disease. CONCLUSIONS: Cancers associated with Graves' disease seems to be more aggressive than those associated with MTG or UTG. Thus, we suggest that patients with Graves' disease be carefully monitored for the detection of thyroid nodules. Ultrasonography seems to be the best modality to detect such nodules

Is the anteroposterior and transverse diameter ratio of nonpalpable thyroid nodules a sonographic criteria for recommending fine-needle aspiration cytology?

BACKGROUND: As a consequence of the increasing application of ultrasound (US) technology, the detection of asymptomatic nonpalpable thyroid nodules has generally increased. The aim of our study was to assess if the anteroposterior and transverse diameter ratio of nonpalpable thyroid nodules (A/T) > or = 1 could be a sonographic criterion for recommending fine-needle aspiration cytology (FNAC). METHODS: From January 2002 to January 2004, 828 consecutive solid nonpalpable thyroid nodules were evaluated by ultrasonography, colour-Doppler and FNAC in our department. Cases were selected from 2217 patients, referred to our thyroid unit for US-guided FNAC from the greater Brescia area, an endemic zone for goitre. Entry criteria included the presence at US of a solid thyroid nodule that was nonpalpable at physical examination, euthyroid condition and no previous diagnosis of thyroid malignancy. All patients with suspicious or malignant cytology underwent surgery. RESULTS: One hundred and twenty-seven nodules with inadequate cytology were excluded from the study. Thyroid malignancy was observed in 67 (9.6%) nodules. At US, cancers presented a solid hypoechoic appearance in 79.1% of cases, blurred margins in 47.8%, microcalcification in 73.1%, intranodular vascular pattern in 56.7% and A/T > or = 1 in 83.6%. A hypoechoic appearance (OR 4.3), blurred margins (OR 2.6), microcalcification (OR 6.1), intranodular vascular pattern (OR 10.2) and A/T > or = 1 (OR 22.4) were independent risk factors of malignancy. CONCLUSIONS: A/T > or = 1 in conjunction with at least one other sonographic risk factor is able to detect the majority of carcinoma and, moreover, it limits the FNAC procedures to only 15.9% of all the nodules

Recurrent pericarditis: autoimmune or autoinflammatory?

Idiopathic recurrent acute pericarditis (IRAP) represents the most troublesome complication of acute pericarditis and occurs in up to 20-50% of patients. It is generally idiopathic or postcardiac injury. IRAP is a disease of suspected immune-mediated pathogenesis. On the other hand, it has been suggested that some of these patients might have an atypical or subclinical form of an autoinflammatory disease, e.g. genetic disorders characterized by primary dysfunction of the innate immune system and caused by mutations of genes involved in the inflammatory response. We found that IRAP patients were negative for mutations associated with familial Mediterranean fever, but 6% (8/131 patients) carry a mutation in the TNFRSF1A gene, encoding the receptor for tumor necrosis factor-alfa. C-reactive protein (CRP) may be useful to follow the disease activity and guide the appropriate length of therapy, with continuation of the attack doses of the drugs until CRP normalization, at which time tapering may be considered. IRAP often needs a multidrug therapy: NSAIDs or aspirin at high dosages every 6-8h, corticosteroids only rarely, at low dosages and with a very gradual tapering (months) and colchicine at low dosages if tolerated. Anakinra could be a solution for patients who do not tolerate other therapies

Effect of Anakinra on Recurrent Pericarditis Among Patients With Colchicine Resistance and Corticosteroid Dependence The AIRTRIP Randomized Clinical Trial

IMPORTANCE Anakinra, an interleukin 1 beta recombinant receptor antagonist, may have potential to treat colchicine-resistant and corticosteroid-dependent recurrent pericarditis. OBJECTIVE To determine the efficacy of anakinra for colchicine-resistant and corticosteroid-dependent recurrent pericarditis. DESIGN, SETTING, AND PARTICIPANTS The Anakinra-Treatment of Recurrent Idiopathic Pericarditis (AIRTRIP) double-blind, placebo-controlled, randomized withdrawal trial (open label with anakinra followed by a double-blind withdrawal step with anakinra or placebo until recurrent pericarditis occurred) conducted among 21 consecutive patients enrolled at 3 Italian referral centers between June and November 2014 (end of follow-up, October 2015). Included patients had recurrent pericarditis (with &gt;= 3 previous recurrences), elevation of C-reactive protein, colchicine resistance, and corticosteroid dependence. INTERVENTIONS Anakinra was administered at 2 mg/kg per day, up to 100 mg, for 2 months, then patients who responded with resolution of pericarditis were randomized to continue anakinra (n = 11) or switch to placebo (n = 10) for 6 months or until a pericarditis recurrence. MAIN OUTCOMES AND MEASURES The primary outcomes were recurrent pericarditis and time to recurrence after randomization. RESULTS Eleven patients (7 female) randomized to anakinra had a mean age of 46.5 (SD, 16.3) years; 10 patients (7 female) randomized to placebo had a mean age of 44 (SD, 12.5) years. All patients were followed up for 12 months. Median follow-up was 14 (range, 12-17) months. Recurrent pericarditis occurred in 9 of 10 patients (90%; incidence rate, 2.06% of patients per year) assigned to placebo and 2 of 11 patients (18.2%; incidence rate, 0.11% of patients per year) assigned to anakinra, for an incidence rate difference of -1.95%(95% CI, -3.3% to -0.6%). Median flare-free survival (time to flare) was 72 (interquartile range, 64-150) days after randomization in the placebo group and was not reached in the anakinra group (P &lt;. 001). During anakinra treatment, 20 of 21 patients (95.2%) experienced transient local skin reactions: 1 (4.8%) herpes zoster, 3 (14.3%) transaminase elevation, and 1 (4.8%) ischemic optic neuropathy. No patient permanently discontinued the active drug. No adverse events occurred during placebo treatment. CONCLUSION AND RELEVANCE In this preliminary study of patients with recurrent pericarditis with colchicine resistance and corticosteroid dependence, the use of anakinra compared with placebo reduced the risk of recurrence over a median of 14 months. Larger studies are needed to replicate these findings as well as to assess safety and longer-term efficacy
