CACS, CCTA and mCAD-LT score in the pre-transplant assessment of coronary artery disease and the prediction of post-transplant cardiovascular events.

BACKGROUND: The optimal cardiovascular assessment of liver transplant (LT) candidates is unclear. We aimed to evaluate the performance of CT-based coronary tests (coronary artery calcium score [CACS] and coronary CT angiography [CCTA]) and a modification of the CAD-LT score (mCAD-LT, excluding family history of CAD) to diagnose significant coronary artery disease (CAD) before LT and predict the incidence of post-LT cardiovascular events (CVE). METHODS: We retrospectively analysed a single-centre cohort of LT candidates who underwent non-invasive tests; invasive coronary angiography (ICA) was performed depending on the results of non-invasive tests. mCAD-LT was calculated in all patients. RESULTS: Six-hundred-and-thirty-four LT candidates were assessed and 351 of them underwent LT. CACS, CCTA and ICA were performed in 245, 123 and 120 LT candidates, respectively. Significant CAD was found in 30% of patients undergoing ICA. The AUROCs of mCAD-LT (.722) and CCTA (.654) were significantly higher than that of CACS (.502) to predict the presence of significant CAD. Specificity of the tests ranged between 31% for CCTA and 53% for CACS. Among patients who underwent LT, CACS ≥ 400 and mCAD-LT were independently associated with the incidence of CVE; in patients who underwent CCTA before LT, significant CAD at CCTA also predicted post-LT CVE. CONCLUSION: In this cohort, mCAD-LT score and CT-based tests detect the presence of significant CAD in LT candidates, although they tend to overestimate it. Both mCAD-LT score and CT-based tests classify LT recipients according to their risk of post-LT CVE and can be used to improve post-LT risk mitigation.

Disease phenotypes in adult patients with suspected undifferentiated autoinflammatory diseases and PFAPA syndrome: Clinical and therapeutic implications.

BACKGROUND: Undifferentiated autoinflammatory diseases are characterized by recurrent or persistent fever, usually combined with other inflammatory manifestations, and negative or inconclusive genetic studies for monogenic autoinflammatory disorders. AIMS: To define and characterize disease phenotypes in adult patients diagnosed in an adult reference center with undifferentiated autoinflammatory diseases, and to analyze the efficacy of the drugs used in order to provide practical diagnostic and therapeutic recommendations. METHODS: Retrospective study (2015-2022) of patients with undifferentiated autoinflammatory diseases among all patients visited in our reference center. Demographic, clinical, laboratory features and detailed therapeutic information was collected. RESULTS: Of the 334 patients with a suspected autoinflammatory disease, 134 (40%) patients (61% women) were initially diagnosed with undifferentiated autoinflammatory diseases. Mean age at disease onset and at diagnosis was 28.7 and 37.7 years, respectively. In 90 (67.2%) patients, symptoms started during adulthood. Forty-four (32.8%) patients met diagnostic/classification criteria for adult PFAPA syndrome. In the remaining patients, four additional phenotypes were differentiated according to the predominant manifestations: a) Predominantly fever phenotype (n = 18; 13.4%); b) Predominantly abdominal/pleuritic pain phenotype (n = 9; 6.7%); c) Predominantly pericarditis phenotype (n = 18; 13.4%), and d) Complex syndrome phenotype (n = 45; 33.6%). Prednisone (mainly on demand), colchicine and anakinra were the drugs commonly used. Overall, complete responses were achieved with prednisone in 41.3%, colchicine in 40.2%, and anakinra in 58.3% of patients in whom they were used. By phenotypes, prednisone on demand was more effective in adult PFAPA syndrome and colchicine in patients with the abdominal/pleuritic pain pattern and PFAPA syndrome. Patients with complex syndrome achieved complete responses with prednisone (21.9%), colchicine (25.7%) and anakinra (44.4%), and were the group more often requiring additional immunosuppressive drugs. CONCLUSIONS: The analysis of the largest single-center series of adult patients with undifferentiated autoinflammatory diseases identified and characterized different disease phenotypes and their therapeutic approaches. This study is expected to contribute to increase the awareness of physicians for an early identification of these conditions, and to provide the best known therapeutic options.

Persistent lymph nodes after curative chemoradiotherapy for head and neck cancer: imaging predictors of response for decision-making.

PURPOSE: To identify response predictors in patients with head and neck squamous cell carcinoma (N + HNSCC) and persistent lymph nodes after curative chemoradiotherapy treatment (CCRT). MATERIALS AND METHODS: Consecutive patients with N + HNSCC treated with CCRT and persistent lymph nodes at first follow-up between 2015 and 2021 were identified and analyzed. Complete response was defined as the absence of lymph node metastatic involvement in patients with salvage lymphadenectomy or the absence of progression after 1 year of successive follow-ups. Tumour type and location, staging, and human papillomavirus (HPV) status were considered for analysis. The number and size of lymph nodes, type, shape, enhancement and margins on diagnostic and follow-up CT were also analyzed. RESULTS: The cohort included 46 patients with 134 pathological lymph nodes. Logistic regression models showed the following variables to be significant: performance of salvage lymphadenectomy (OR 0.094, [CI 95% 0.004-0.61], p = 0.037); the type of lymphadenopathy on diagnostic CE-CT (solid vs. cystic) (N1: OR = 4.11, [CI 95% 1.11-17.93], p = 0.042 and N3: OR 6.42, [CI 95% 1.2-42.56], p = 0.036); the change of shape (round to oval) on the follow-up CE-CT (OR 9.76, [CI 95% 1.79-8.57], p = 0.016) and the time in days between CCRT and the first follow-up CE-CT (OR 1.06, [CI 95% 1.004-1.13], p = 0.048). CONCLUSIONS: In our experience, the presence of solid lymph nodes on pre-treatment CT and the change in shape from round to oval on post-treatment CT are predictors of response to treatment in patients with N + HNSCC persistent lymph nodes after CCRT. Increasing the temporal interval between treatment and follow-up CT should be considered to avoid unnecessary nodal dissections.

Characterisation of the coexistence between sarcoidosis and Sjögren's syndrome. Analysis of 43 patients.

OBJECTIVES: To characterise the key epidemiological, clinical, immunological, imaging, and pathological features of the coexistence between sarcoidosis and Sjögren's syndrome (SS). METHODS: All centres included in two large multicentre registries (the Sjögren Syndrome Big Data Consortium and the Sarco-GEAS-SEMI Registry) were contacted searching for potential cases of coexistence between SS and sarcoidosis seen in daily practice. Inclusion criteria were the fulfilment of the current classification criteria both for SS (2016 ACR/EULAR) and sarcoidosis (WASOG). The following features were considered for evaluating a coexisting immunopathological scenario between the two diseases: non-caseating granulomas (NCG), focal lymphocytic sialadenitis (FLS) and positive anti-Ro antibodies. RESULTS: We identified 43 patients who fulfilled the inclusion criteria (38 women, with a mean age of 53 years at diagnosis of SS and of 52 years at diagnosis of sarcoidosis). In 28 (65%) cases, sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of patients with an already diagnosed SS, while in the remaining 15 (35%), SS was diagnosed during the follow-up of an already diagnosed sarcoidosis. Patients in whom sarcoidosis was diagnosed first showed a lower mean age (43.88 vs. 55.67 years, p=0.005) and were less frequently women (73% vs. 96%, p=0.04) in comparison with those in whom sarcoidosis was diagnosed concomitantly with SS, or during the follow-up of an already diagnosed SS. We identified the following immunopathological scenarios: a combination of NCG involving extrasalivary tissues and anti-Ro antibodies in 55% of patients, a coexistence of both pathological scenarios (extrasalivary NCG and FLS in MSGB) in 42% (with positive anti-Ro antibodies in two thirds of cases), and NCG involving salivary glands and anti-Ro antibodies in 3% of cases. CONCLUSIONS: We have characterised the largest reported series of patients who fulfilled the current classification criteria for both SS and sarcoidosis. This implies that sarcoidosis (and not just the presence of isolated NCG on salivary gland biopsy) may, like other systemic autoimmune diseases, coexist with SS, and that a sarcoidosis diagnosis does not preclude the development of SS in the future.

CO2-TOLMS for laryngeal cancer in the elderly, pushing the boundaries of partial laryngectomy.

INTRODUCTION: CO2 transoral laser microsurgery (CO2-TOLMS) has pushed the indications of partial surgery of the larynx regardless the age of the patient. OBJECTIVE: To evaluate the complications and the oncologic and functional outcomes of CO2-TOLMS in patients older and younger than 70 years. METHODS: Retrospective analysis of 1244 consecutive laryngeal carcinomas treated with CO2-TOLMS. Complications, length of hospitalization, functional and survival outcomes were evaluated. RESULTS: The mean age was 64.2 ±â€¯11.1 years (20-96). Four hundred and sixteen patients were older than 70 years and 104 older than 80 years. The main location was the glottis (912), followed by the supraglottis (332). There were no differences in pT classification between the age groups. No differences were observed in voice outcomes. A higher rate of signs of aspiration at the glottic location was observed for those older than 70 years (2.1 % vs 5 %, p = 0.027). The need for definitive gastrostomy in supraglottic tumours was higher in those older than 70 years (0 % vs 6.5 %, p: 0.001). In the glottis, no differences in tracheostomy or gastrostomy rates were observed. Five-year overall survival was lower in the older than 70 years. No differences in disease-specific survival were observed in early stages for both locations, but a lower survival was observed in stage III glottic cancer for the older than 70 years. CONCLUSIONS: CO2-TOLMS is a valid treatment for laryngeal carcinomas in the elderly, with a reduced number of complications and good functional and oncologic outcomes.

Transoral laser microsurgery in locally advanced laryngeal cancer: Prognostic impact of anterior versus posterior compartments.

BACKGROUND: To evaluate the importance of larynx compartments in the prognosis of T3-T4a laryngeal cancer treated with transoral laser microsurgery. METHODS: Two hundred and two consecutive pT3-T4a larynx carcinomas. Pre-epiglottic space involvement, anterior and posterior paraglottic space (PGS) involvement, vocal cord, and arytenoid mobility were determined. Local control with laser (LC), overall survival (OS), disease-specific survival (DSS), and laryngectomy-free survival (LFS) were evaluated. RESULTS: The lowest LC was found in tumors with fixed arytenoid. In the multivariate analysis, positive margins (hazard ratio [HR] = 0.289 [0.085-0.979]) and anterior (HR = 0.278 [0.128-0.605]) and posterior (HR = 0.269 [0.115-0.630]) PGS invasion were independent factors of a reduced LC. Anterior (HR = 3.613 [1.537-8.495]) and posterior (HR = 5.195 [2.167-12.455]) PGS involvement were independent factors of total laryngectomy. Five-year OS, DSS, and LFS rates were 63.9%, 77.5%, and 77.5%, respectively. Patients with posterior PGS presented a reduced 5-year LFS. CONCLUSIONS: Tumor classification according to laryngeal compartmentalization depicts strong correlation with LC and LFS.

Vertebral fracture risk in glucocorticoid-induced osteoporosis: the role of hypogonadism and corticosteroid boluses.

OBJECTIVE: The aim of this study was to identify the risk factors associated with fragility fracture (FF) development in glucocorticoid (GC)-treated patients. METHODS: 127 patients (aged 62±18 years, 63% women) on GC-treatment (mean dose 14.5±14.1 mg/day and duration 47.7±69 months) were included. The clinical data collected included bone metabolism study (including gonadal axis), GC-treatment, disease activity, dual-energy X-ray absorptiometry analysis (evaluating densitometric osteoporosis (OP) and trabecular bone score (TBS) degraded microarchitecture values (DMA)), X-ray (assessing vertebral fractures (VF)), FRAX risk (GC-adjusted) and previous FF. RESULTS: 17% of the patients had VF, 28% FF (VF and/or non-VF), 29% OP and 52% DMA. Patients with VF received more GC boluses (57.1% vs 29.5%, p=0.03), were older (68±13 vs 60±19 years, p=0.02), postmenopausal (100% vs 67%, p=0.02), had low testosterone levels (57% vs 11%, p=0.02), lower TBS values (1.119±0.03 vs 1.237±0.013, p<0.001) and higher FRAX risk (17.2±16 vs 9.3±7.6, p=0.003). Patients with FF showed higher accumulated GC doses (16.6±18.4 vs 11.1±12.9 g, p=0.046). On multivariate analysis, hypogonadism (OR 12.38; 95% CI 1.85 to >100, p=0.01) and having received GC boluses (OR 3.45; 95% CI 1.04 to 12.15, p=0.01) were the main factors related to VF. Hypogonadism (OR 7.03; 95% CI 1.47 to 38.37, p=0.01) and FRAX >20 (OR 7.08; 95% CI 1.28 to 53.71, p=0.02) were factors related to FF. CONCLUSION: Hypogonadism is the principal risk factor for developing fractures in GC-treated men and women, whereas receiving GC boluses is a major factor for VF. These results indicate the importance of evaluating the gonadal axis in these patients.

Trabecular bone score improves fracture risk assessment in glucocorticoid-induced osteoporosis.

OBJECTIVE: To analyse the clinical utility of trabecular bone score (TBS) evaluation for fracture risk assessment in glucocorticoid (GC)-treated patients compared with BMD assessment. METHODS: One hundred and twenty-seven patients on GC treatment were included [mean age 62 (18) years, 63% women] in this cross-sectional study. The medical history, anthropometric data, lumbar and femoral BMD (DXA) [considering osteoporosis (OP): T-score ⩽-2.5], TBS (considering degraded microarchitecture: <1.230) and dorsolumbar X-ray [to assess vertebral fractures (VF)] were evaluated. BMD and TBS sensitivity, specificity, and positive and negative predictive values (PPV, NPV) were evaluated to determine the diagnostic accuracy of the two methods. RESULTS: All patients were receiving GC treatment for autoimmune diseases during 47.7 (68.9) months at a mean daily dose of 14.5 mg; 17% had VF, 28% any type of fragility fracture (VF + non-VF), 29% OP and 52% degraded microarchitecture. Degraded microarchitecture was significantly more frequent than densitometric OP in patients with VF (76% vs 38%) and with any fragility fracture (69% vs 36%). For VF, TBS and BMD sensitivity, specificity, PPV, and NPV were 0.76, 0.53, 0.25 and 0.92, and 0.38, 0.72, 0.22 and 0.85, respectively. Specificity increased to 0.89 for VF and 0.9 for any fragility fracture on combining BMD+TBS. TBS had better ability than BMD to discriminate between patients with fracture, especially VF (area under the curve = 0.73). CONCLUSION: TBS seems to have greater discriminative power than BMD for fracture risk assessment in GC-treated patients, confirming the utility of this method as a complementary tool in the diagnosis of GC-induced OP.

Factors of local recurrence and organ preservation with transoral laser microsurgery in laryngeal carcinomas; CHAID decision-tree analysis.

BACKGROUND: Indications of transoral laser microsurgery (TLM) are conditioned by the risk of local relapse. OBJECTIVE: To evaluate prognostic factors of local relapse and local control with TLM (LC-TLM). METHODS: Local relapse and LC-TLM were evaluated in 1119 patients. Logistic regression and CHAID decision tree analysis were performed. RESULTS: Local relapse correlated to previous radiotherapy failure (8.45, CI 95%: 2.64-27.03; P < .001), paraglottic involvement (2.42, CI: 1.41-4.15; P = .001), anterior commissure involvement (2.12, CI: 1.43-3.14; P < .001), grade of differentiation (1.74, CI: 1.18-2.57; P = .005), and alcohol consumption (1.4, CI: 0.99-1.98; P = .057). Local relapse tended to inversely correlate with experience (0.73, CI: 0.51-1.03; P = .078). The most important factors for local relapse were previous radiotherapy failure and anterior commissure involvement. LC-TLM inversely correlated with previous radiotherapy failure (0.09, CI: 0.03-0.28; P < .001), paraglottic involvement (0.25, CI: 0.14-0.43; P < .001), anterior commissure involvement (0.49, CI: 0.32-0.77; P = .007), margins (0.56, CI: 0.30-1.04; P = .068), and differentiation (0.68, CI: 0.44-1.05; P = .087). LC-TLM correlated with experience (1.71, CI: 1.13-2.55; P = .010). The most important factors for LC-TLM were previous radiotherapy failure and paraglottic involvement. CONCLUSION: Previous radiotherapy failure is the most important factor for local relapse and LC-TLM. In primary treatments, anterior commissure involvement and paraglottic involvement are the most important factors for local relapse and LC-TLM, respectively.

The Burden of Comorbidity and Complexity in Sarcoidosis: Impact of Associated Chronic Diseases.

PURPOSE: To evaluate comorbidity, complexity and poor outcomes in patients with sarcoidosis and to compare those scores with a control group. METHODS: 218 consecutive patients were diagnosed with sarcoidosis according to the ATS/ERS/WASOG criteria; extrathoracic involvement was evaluated using the 2014 WASOG organ assessment instrument. Sarcoidosis patients were compared with an age- and gender-matched control group of primary care outpatients without sarcoidosis. Comorbidities were assessed retrospectively using the Charlson Comorbidity Index (CCI); complexity was evaluated according to the classification into Clinical Risk Groups (CRG) and severity levels. RESULTS: The cohort included 142 women and 76 men; the mean age was 47.1 years at diagnosis of sarcoidosis and 55.9 years at the last visit. Patients with a CCI > 1 had a higher frequency of calcium/vitamin D abnormalities (p < 0.001), kidney involvement (p = 0.005) and a higher mortality rate (p < 0.001) compared with patients with a CCI ≤ 1. Patients with a CRG ≥ 6 had a higher frequency of extrathoracic involvement (p = 0.039), calcium/vitamin D abnormalities (p = 0.019) and treatment with glucocorticoids (p = 0.032) compared with patients with a CRG < 6. 11% patients died after a mean follow-up of 102.3 months. Country of birth, kidney involvement and extrathoracic disease were significantly associated with death. Patients with sarcoidosis had a higher frequency of liver (p < 0.001), pulmonary (p = 0.002) and autoimmune disease (p = 0.011) and cancer (p = 0.007) compared with the control group. CONCLUSION: We found higher rates of comorbidity and complexity in patients with sarcoidosis compared with a control group. Liver, pulmonary, autoimmune and neoplastic diseases were the main comorbidities found in patients with sarcoidosis.

Transoral laser microsurgery for locally advanced (T3-T4a) supraglottic squamous cell carcinoma: Sixteen years of experience.

BACKGROUND: Controversy exists regarding treatment of advanced laryngeal cancer. The purpose of this study was to evaluate the oncologic and functional outcomes of T3 to T4a supraglottic squamous carcinomas treated with transoral laser microsurgery (TLM). METHODS: We conducted a retrospective analysis from an SPSS database. Primary outcomes were: locoregional control, overall survival (OS), disease-specific survival (DSS), laryngectomy-free survival, and function-preservation rates. Secondary objectives were: rate of tracheostomies and gastrostomies according to age. Risk factors for local control and larynx preservation were also evaluated. RESULTS: One hundred fifty-four consecutive patients were chosen for this study. Median follow-up was 40.7 + /- 32.8 months. Five and 10-year OS, DSS, and laryngectomy-free survival were 55.6% and 47%, 67.6% and 58.6%, and 75.2% and 59.5%, respectively. Paraglottic involvement was an independent factor for larynx preservation. Six patients (3.9%) needed a definitive tracheostomy, a gastrostomy, or both. The gastrostomy rate was higher in the group of patients above 65 years of age (p = .03). Five-year laryngectomy-free survival with preserved function was 74.5%. CONCLUSION: TLM constitutes a true alternative for organ preservation in locally advanced supraglottic carcinomas with good oncologic and functional outcomes. © 2016 Wiley Periodicals, Inc.

Monthly ibandronate versus weekly risedronate treatment for low bone mineral density in stable renal transplant patients.

INTRODUCTION: Bisphosphonates may aid in treating and preventing bone loss promoted by chronic immunosuppressive treatment and secondary hyperparathyroidism in renal transplant (RT) patients. However, the effectiveness of bisphosphonates is compromised by poor patient compliance. The objective of the study was to compare the effects of once monthly ibandronate with those of weekly risedronate administration on bone mineral density (BMD) and renal function in RT patients. PATIENTS AND METHODS: Sixty-nine patients were prospectively recruited who were at least 12 months post-RT and were treated with either oral ibandronate 150 mg monthly (n=35) or oral risedronate 35 mg weekly (n=34). At baseline and 1 year, creatinine, calcium, alkaline phosphatase, and i-parathyroid hormone were measured, and BMD was determined by dual-energy X-ray absorptiometry. RESULTS: Group I consisted of 35 patients (28 women) treated with ibandronate who were of a mean age of 63±12 years. Group II consisted of 34 patients (30 women) treated with risedronate who were of a mean age of 64±10 years. Lumbar BMD was as follows: baseline T-score (group I vs. group II) of -1.7±0.8 versus -1.9±0.8 (P=NS); and annual T-score of -1.3±0.6 versus -1.4±0.8 (P=NS). After 1 year, lumbar BMD improved to reveal a T-score of -1.3±0.6 in the ibandronate group (P<0.01) and -1.4±0.8 in the risedronate group (P<0.01). Femoral BMD was as follows: baseline T-score (group I vs. group II) of -2.1±0.7 versus -2.2±0.6 (P=NS); and annual T-score of -1.8±0.9 versus -1.8±0.8 (P=NS). Cortical bone also improved in both groups, but results were not statistically significant. No changes in renal function and no adverse effects were observed. CONCLUSION: In RT patients with low BMD, no difference in effects on BMD, renal function, or adverse effects were observed between monthly oral ibandronate and weekly oral risedronate administration.

DXA variations and fractures after simultaneous pancreas-renal transplantation: results of a long-term follow-up.

Simultaneous pancreas-kidney transplant (SPKT) has been associated with an increased risk of fracture. We prospectively evaluated the long-term effects of SPKT on bone mineral density (BMD) and fracture risk. During 1998 to 1999, 29 participants were consecutively monitored, and 18 completed the 10-year follow-up. Laboratory blood parameters, lumbar-dorsal radiography, and DEXA were determined at baseline, 1 year, and 10 years. The medical record was reviewed for peripheral fragility fractures. The BMD revealed no changes between baseline and 1 or 10 years after SPKT. Lumbar-dorsal radiography showed 0% asymptomatic vertebral fractures at baseline and after 1 year with 16.7% at 10 years. Vertebral asymptomatic fractures were correlated with acute rejection episodes (P = 0.025). During the first year, no nonvertebral fractures were identified. At the end of the follow-up, 5 nonvertebral fractures in 4 patients were reported. Dorsal and lumbar spine fractures correlated with lumbar spine t score (r = -0.591, P =0.022) and peripheral fractures with femoral neck t score (r = -0.633, P = 0.013). Patients with SPKT did not show long-term significant loss of BMD. The incidence of vertebral fractures was low and related to steroid treatment; the incidence of peripheral fractures was higher and independent of clinical or biochemical parameters.
