Nosocomial COVID-19: A Nationwide Spanish Study.

INTRODUCTION: SARS-CoV-2 is a highly contagious virus, and despite professionals' best efforts, nosocomial COVID-19 (NC) infections have been reported. This work aimed to describe differences in symptoms and outcomes between patients with NC and community-acquired COVID-19 (CAC) and to identify risk factors for severe outcomes among NC patients. METHODS: This is a nationwide, retrospective, multicenter, observational study that analyzed patients hospitalized with confirmed COVID-19 in 150 Spanish hospitals (SEMI-COVID-19 Registry) from March 1, 2020, to April 30, 2021. NC was defined as patients admitted for non-COVID-19 diseases with a positive SARS-CoV-2 test on the fifth day of hospitalization or later. The primary outcome was 30-day in-hospital mortality (IHM). The secondary outcome was other COVID-19-related complications. A multivariable logistic regression analysis was performed. RESULTS: Of the 23,219 patients hospitalized with COVID-19, 1,104 (4.8%) were NC. Compared to CAC patients, NC patients were older (median 76 vs. 69 years; p < 0.001), had more comorbidities (median Charlson Comorbidity Index 5 vs. 3; p < 0.001), were less symptomatic (p < 0.001), and had normal chest X-rays more frequently (30.8% vs. 12.5%, p < 0.001). After adjusting for sex, age, dependence, COVID-19 wave, and comorbidities, NC was associated with lower risk of moderate/severe acute respiratory distress syndrome (ARDS) (adjusted odds ratio [aOR]: 0.72; 95% confidence interval [CI]: 0.59-0.87; p < 0.001) and higher risk of acute heart failure (aOR: 1.40; 1.12-1.72; p = 0.003), sepsis (aOR: 1.73; 1.33-2.54; p < 0.001), and readmission (aOR: 1.35; 1.03-1.83; p = 0.028). NC was associated with a higher case fatality rate (39.1% vs. 19.2%) in all age groups. IHM was significantly higher among NC patients (aOR: 2.07; 1.81-2.68; p < 0.001). Risk factors for increased IHM in NC patients were age, moderate/severe dependence, malignancy, dyspnea, moderate/severe ARDS, multiple organ dysfunction syndrome, and shock; odynophagia was associated with lower IHM. CONCLUSIONS: NC is associated with greater mortality and complications compared to CAC. Hospital strategies to prevent NC must be strengthened.

Sporadic, non-functional, gastrin-producing duodenal neuroendocrine tumors: A retrospective study of an infrequent disease.

OBJECTIVES: Non-functioning gastrin-producing neuroendocrine neoplasms (NEN) of the duodenum are rare gastrointestinal tumors without a clinical syndrome due to gastrin production. Their incidence has significantly increased as an incidental finding during endoscopic studies. The aim of this study was to describe the characteristics and prognostic factors of this emergent and infrequent neoplasm. METHODS: We performed a retrospective observational study based on the duodenal NENs samples with positive staining for gastrin at the Department of Pathology, University Hospital 12-de-Octubre (Madrid, Spain) between 2000 and 2017. Patients with clinically functional tumors ([Zollinger-Ellison syndrome] or gastrin >1000 pg/mL), with previously diagnosed multiple endocrine neoplasia (MEN) syndrome or synchronous neoplasia were excluded. Clinicopathological and therapeutic variables, follow-up, recurrence, and mortality data were collected. RESULTS: In all, 21 patients were included. Most of the tumors were diagnosed incidentally as a single small polypoid lesion limited to mucosa/submucosa and with a low histological grade. Four (19.0%) patients presented with metastatic involvement at diagnosis (lymphatic and/or hepatic). These four patients also had a high or intermediate mitotic grade and infiltration further than submucosa. Local resection was applied in most cases as curative treatment. There were two cases of tumor recurrence and two tumor-related deaths with a 5-year disease-free survival of 81.0%. CONCLUSIONS: The majority of these tumors were diagnosed at a localized stage and had a good prognosis with treatment. Nevertheless, given the potential metastatic risk, a close follow-up is necessary, especially in those with aggressive pathological factors such as deep infiltration or high histological grade.

Effective Natural Killer Cell Degranulation Is an Essential Key in COVID-19 Evolution.

NK degranulation plays an important role in the cytotoxic activity of innate immunity in the clearance of intracellular infections and is an important factor in the outcome of the disease. This work has studied NK degranulation and innate immunological profiles and functionalities in COVID-19 patients and its association with the severity of the disease. A prospective observational study with 99 COVID-19 patients was conducted. Patients were grouped according to hospital requirements and severity. Innate immune cell subpopulations and functionalities were analyzed. The profile and functionality of innate immune cells differ between healthy controls and severe patients; CD56dim NK cells increased and MAIT cells and NK degranulation rates decreased in the COVID-19 subjects. Higher degranulation rates were observed in the non-severe patients and in the healthy controls compared to the severe patients. Benign forms of the disease had a higher granzymeA/granzymeB ratio than complex forms. In a multivariate analysis, the degranulation capacity resulted in a protective factor against severe forms of the disease (OR: 0.86), whereas the permanent expression of NKG2D in NKT cells was an independent risk factor (OR: 3.81; AUC: 0.84). In conclusion, a prompt and efficient degranulation functionality in the early stages of infection could be used as a tool to identify patients who will have a better evolution.

A predictive score at admission for respiratory failure among hospitalized patients with confirmed 2019 Coronavirus Disease: a simple tool for a complex problem.

Coronavirus Disease 2019 (COVID-19) pandemic has implacably stricken on the wellness of many countries and their health-care systems. The aim of the present study is to analyze the clinical characteristics of the initial wave of patients with COVID-19 attended in our center, and to identify the key variables predicting the development of respiratory failure. Prospective design study with concurrent data retrieval from automated medical records of all hospitalized adult patients who tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rRT-PCR assay performed on respiratory samples from March 2nd to 18th, 2020. Patients were followed up to May 1st, 2020 or death. Respiratory failure was defined as a PaO2/FiO2 ratio ≤ 200 mm Hg or the need for mechanical ventilation (either non-invasive positive pressure ventilation or invasive mechanical ventilation). We included 521 patients of whom 416 (81%) had abnormal Chest X-ray on admission. Median age was 64.6 ± 18.2 years. One hundred eighty-one (34.7%) developed respiratory failure after a median time from onset of symptoms of 9 days (IQR 6-11). In-hospital mortality was 23.8% (124/521). The modeling process concluded into a logistic regression multivariable analysis and a predictive score at admission. Age, peripheral pulse oximetry, lymphocyte count, lactate dehydrogenase and C-reactive protein were the selected variables. The model has a good discriminative capacity with an area under the ROC curve of 0.85 (0.82-0.88). The application of a simple and reliable score at admission seems to be a useful tool to predict respiratory failure in hospitalized COVID-19 patients.

Anti-Phospholipid Antibodies and COVID-19 Thrombosis: A Co-Star, Not a Supporting Actor.

BACKGROUND: COVID-19 clinical features include a hypercoagulable state that resembles the antiphospholipid syndrome (APS), a disease characterized by thrombosis and presence of antiphospholipid antibodies (aPL). The relationship between aPL-presence and the appearance of thrombi as well as the transience or permanence of aPL in COVID-19 patients is not sufficiently clear. METHODS: A group of 360 COVID-19 patients were followed-up for 6 months. Classic aPL, anti-B2GPI IgA, anti-phosphatidylserine/prothrombin IgG/M and anti-SARS-CoV-2 antibodies were determined at acute phase and >12 weeks later. The reference group included 143 healthy volunteers of the same age-range distribution. RESULTS: aPL prevalence was similar in COVID-19 patients and the reference population. aPL presence in both determinations was significantly associated with thrombosis (OR: 2.33 and 3.71), strong agreement being found for classic aPL and anti-B2GPI IgA (Weighted kappa: 0.85-0.91). Thrombosis-associated aPL occurred a median of 17 days after hospital admission (IQR: 6-28) vs. 4 days for the rest (IQR: 3-7). Although anti-SARS-CoV-2 antibodies levels increased during convalescence, aPL hardly changed. CONCLUSIONS: Most COVID-19 patients would carry these aPL before the infection. At least two mechanisms could be behind thrombosis, early immune-dysregulation-mediated thrombosis after infection and belated-aPL-mediated thrombosis, with SARS-CoV-2 behaving as a second hit.

Clinical Characteristics and Risk Factors of Respiratory Failure in a Cohort of Young Patients Requiring Hospital Admission with SARS-CoV2 Infection in Spain: Results of the Multicenter SEMI-COVID-19 Registry.

BACKGROUND: Age is a risk factor for COVID severity. Most studies performed in hospitalized patients with SARS-CoV2 infection have shown an over-representation of older patients and consequently few have properly defined COVID-19 in younger patients who require hospital admission. The aim of the present study was to analyze the clinical characteristics and risk factors for the development of respiratory failure among young (18 to 50 years) hospitalized patients with COVID-19. METHODS: This retrospective nationwide cohort study included hospitalized patients from 18 to 50 years old with confirmed COVID-19 between March 1, 2020, and July 2, 2020. All patient data were obtained from the SEMI-COVID Registry. Respiratory failure was defined as the ratio of partial pressure of arterial oxygen to fraction of inspired oxygen (PaO2/FiO2 ratio) ≤200 mmHg or the need for mechanical ventilation and/or high-flow nasal cannula or the presence of acute respiratory distress syndrome. RESULTS: During the recruitment period, 15,034 patients were included in the SEMI-COVID-19 Registry, of whom 2327 (15.4%) were younger than 50 years. Respiratory failure developed in 343 (14.7%), while mortality occurred in 2.3%. Patients with respiratory failure showed a higher incidence of major adverse cardiac events (44 (13%) vs 14 (0.8%), p<0.001), venous thrombosis (23 (6.7%) vs 14 (0.8%), p<0.001), mortality (43 (12.5%) vs 7 (0.4%), p<0.001), and longer hospital stay (15 (9-24) vs 6 (4-9), p<0.001), than the remaining patients. In multivariate analysis, variables associated with the development of respiratory failure were obesity (odds ratio (OR), 2.42; 95% confidence interval (95% CI), 1.71 to 3.43; p<0.0001), alcohol abuse (OR, 2.40; 95% CI, 1.26 to 4.58; p=0.0076), sleep apnea syndrome (SAHS) (OR, 2.22; 95% CI, 1.07 to 3.43; p=0.032), Charlson index ≥1 (OR, 1.77; 95% CI, 1.25 to 2.52; p=0.0013), fever (OR, 1.58; 95% CI, 1.13 to 2.22; p=0.0075), lymphocytes ≤1100 cells/µL (OR, 1.67; 95% CI, 1.18 to 2.37; p=0.0033), LDH >320 U/I (OR, 1.69; 95% CI, 1.18 to 2.42; p=0.0039), AST >35 mg/dL (OR, 1.74; 95% CI, 1.2 to 2.52; p=0.003), sodium <135 mmol/L (OR, 2.32; 95% CI, 1.24 to 4.33; p=0.0079), and C-reactive protein >8 mg/dL (OR, 2.42; 95% CI, 1.72 to 3.41; p<0.0001). CONCLUSIONS: Young patients with COVID-19 requiring hospital admission showed a notable incidence of respiratory failure. Obesity, SAHS, alcohol abuse, and certain laboratory parameters were independently associated with the development of this complication. Patients who suffered respiratory failure had a higher mortality and a higher incidence of major cardiac events, venous thrombosis, and hospital stay.

Presence of Extra-Criteria Antiphospholipid Antibodies Is an Independent Risk Factor for Ischemic Stroke.

Background: Ischemic stroke is the most common and severe arterial thrombotic event in Antiphospholipid syndrome (APS). APS is an autoimmune disease characterized by the presence of thrombosis and antiphospholipid antibodies (aPL), which provide a pro-coagulant state. The aPL included in the classification criteria are lupus anticoagulant, anti-cardiolipin (aCL) and anti-ß2-glycoprotein-I antibodies (aB2GPI) of IgG and IgM isotypes. Extra-criteria aPL, especially IgA aB2GPI and IgG/IgM anti-phosphatidylserine/prothrombin antibodies (aPS/PT), have been strongly associated with thrombosis. However, their role in the general population suffering from stroke is unknown. We aim (1) to evaluate the aPL prevalence in ischemic stroke patients, (2) to determine the role of aPL as a risk factor for stroke, and (3) to create an easy-to-use tool to stratify the risk of ischemic stroke occurrence considering the presence of aPL and other risk factors. Materials and Methods: A cohort of 245 consecutive ischemic stroke patients was evaluated in the first 24 h after the acute event for the presence of classic aPL, extra-criteria aPL (IgA aB2GPI, IgG, and IgM aPS/PT) and conventional cardiovascular risk factors. These patients were followed-up for 2-years. A group of 121 healthy volunteers of the same age range and representative of the general population was used as reference population. The study was approved by the Ethics Committee for Clinical Research (Reference numbers CEIC-14/354 and CEIC-18/182). Results: The overall aPL prevalence in stroke patients was 28% and IgA aB2GPI were the most prevalent (20%). In the multivariant analysis, the presence of IgA aB2GPI (OR 2.40, 95% CI: 1.03-5.53), dyslipidemia (OR 1.70, 95% CI: 1.01-2.84), arterial hypertension (OR 1.82, 95% CI: 1.03-3.22), atrial fibrillation (OR 4.31, 95% CI: 1.90-9.78), and active smoking (OR 3.47, 95% CI: 1.72-6.99) were identified as independent risk factors for ischemic stroke. A risk stratification tool for stroke was created based on these factors (AUC: 0.75). Conclusions: IgA aB2GPI are an important independent risk factor for ischemic stroke. Evaluation of aPL (including extra-criteria) in cardiovascular risk factor assessment for stroke can potentially increase the identification of patients at risk of thrombotic event, facilitating a decision on preventive treatments.

Case Report: Resetting the Humoral Immune Response by Targeting Plasma Cells With Daratumumab in Anti-Phospholipid Syndrome.

Introduction: Monoclonal antibodies (mAb) targeting plasma cells are malignant gammopathy designed and approved therapies. In recent years, these antibodies have also been increasingly introduced for non-malignant conditions such as autoimmune-mediated diseases. The Anti-Phospholipid Syndrome (APS) is an immune-mediated disorder in which autoantibodies against phospholipid associated proteins could elicit the activation of the coagulation cascade in specific situations. Therefore, the mainstream treatment for APS patients is the use of anticoagulant therapy. However, there are refractory patients who would benefit from targeting the antibodies rather than their effects. Rituximab, a B-cell depleting mAb, and intravenous immunoglobulins (IVIG) have been used in APS patients without showing a clear beneficial effect or a significant drop in anti-phospholipid antibody (aPL) levels. Clinical case: We present our first APS case treated with daratumumab, an anti-CD38 mAb, in a 21-year-old patient with APS who presented with recurrent venous thromboembolic events despite adequate anticoagulant therapy. She tested positive for lupus anticoagulant, anti-cardiolipin IgG, anti-beta-2-glycoprotein-I IgG and anti-phosphatidylserine/prothrombin IgG and IgM. She was administered one dose weekly of daratumumab for 4 weeks. The treatment showed an adequate safety profile and was well tolerated. The patient was discharged after undergoing a clinically significant improvement. After the therapy, her levels of positive aPL declined significantly and most continued to decrease during the next three months. The patient experienced a new thrombotic episode two years after the therapy associated with poor adherence to antithrombotic therapy. Conclusions: The treatment with daratumumab showed an adequate safety profile, was well tolerated and led to a significant clinical improvement. Levels of aPL lowered on therapy and the next three months and then rose again during follow-up. Further investigation is needed to better elucidate the role and optimal timing and doses of daratumumab in treatment of refractory APS.

T-Helper Cell Subset Response Is a Determining Factor in COVID-19 Progression.

The immune response type organized against viral infection is determinant in the prognosis of some infections. This work has aimed to study Th polarization in acute COVID-19 and its possible association with the outcome through an observational prospective study. Fifty-eight COVID-19 patients were recruited in the Medicine Department of the hospital "12 de Octubre," 55 patients remaining after losses to follow-up. Four groups were established according to maximum degree of disease progression. T-helper cell percentages and phenotypes, analyzed by flow cytometer, and serum cytokines levels, analyzed by Luminex, were evaluated when the microbiological diagnosis (acute phase) of the disease was obtained. Our study found a significant reduction of %Th1 and %Th17 cells with higher activated %Th2 cells in the COVID-19 patients compared with reference population. A higher percent of senescent Th2 cells was found in the patients who died than in those who survived. Senescent Th2 cell percentage was an independent risk factor for death (OR: 13.88) accompanied by the numbers of total lymphocytes (OR: 0.15) with an AUC of 0.879. COVID-19 patients showed a profile of pro-inflammatory serum cytokines compared to controls, with higher levels of IL-2, IL-6, IL-15, and IP-10. IL-10 and IL-13 were also elevated in patients compared to controls. Patients who did not survive presented significantly higher levels of IL-15 than those who recovered. No significant differences were observed according to disease progression groups. The study has shown that increased levels of IL-15 and a high Th2 response are associated with a fatal outcome of the disease.

Beta-2-Glycoprotein-I Deficiency Could Precipitate an Antiphospholipid Syndrome-like Prothrombotic Situation in Patients With Coronavirus Disease 2019.

OBJECTIVE: Patients with coronavirus disease 2019 (COVID-19) present coagulation abnormalities and thromboembolic events that resemble antiphospholipid syndrome (APS). This work has aimed to study the prevalence of APS-related antigens, antibodies, and immune complexes in patients with COVID-19 and their association with clinical events. METHODS: A prospective study was conducted on 474 adults with severe acute respiratory syndrome coronavirus 2 infection hospitalized in two Spanish university hospitals. Patients were evaluated for classic and extra-criteria antiphospholipid antibodies (aPLs), immunoglobulin G (IgG)/immunoglobulin M (IgM) anticardiolipin, IgG/IgM/immunoglobulin A (IgA) anti-ß2-glicoprotein-I (aß2GPI), IgG/IgM antiphosphatidylserine/prothrombin (aPS/PT), the immune complex of IgA aß2GPI (IgA-aß2GPI), bounded to ß2-glicoprotein-1 (ß2GPI) and ß2GPI levels soon after COVID-19 diagnosis and were followed-up until medical discharge or death. RESULTS: Prevalence of aPLs in patients with COVID-19 was as follows: classic aPLs, 5.8%; aPS/PT, 4.6%; IgA-aß2GPI, 15%; and any aPL, 21%. When patients were compared with individuals of a control group of a similar age, the only significant difference found was the higher prevalence of IgA-aß2GPI (odds ratio: 2.31; 95% confidence interval: 1.16-4.09). No significant differences were observed in survival, thrombosis, or ventilatory failure in aPL-positive versus aPL-negative patients. ß2GPI median levels were much lower in patients with COVID-19 (15.9 mg/l) than in blood donors (168.8 mg/l; P < 0.001). Only 3.5% of patients with COVID-19 had normal levels of ß2GPI (>85 mg/l). Low levels of ß2GPI were significantly associated with ventilatory failure (P = 0.026). CONCLUSION: ß2GPI levels were much lower in patients with COVID-19 than in healthy people. Low ß2GPI-levels were associated with ventilatory failure. No differences were observed in the COVID-19 evolution between aPL-positive and aPL-negative patients. Functional ß2GPI deficiency could trigger a clinical process similar to that seen in APS but in the absence of aPLs.

Impact of viral load at admission on the development of respiratory failure in hospitalized patients with SARS-CoV-2 infection.

The aim of our study was to elucidate if SARS-CoV-2 viral load on admission, measured by real-time reverse transcriptase-polymerase chain reaction (rRT-PCR) cycle threshold (Ct) value on nasopharyngeal samples, was a marker of disease severity. All hospitalized adult patients with a diagnosis of SARS-CoV-2 infection by rRT-PCR performed on a nasopharingeal sample from March 1 to March 18 in our institution were included. The study population was divided according to the Ct value obtained upon admission in patients with high viral load (Ct < 25), intermediate viral load (Ct: 25-30) and low viral load (Ct > 30). Demographic, clinical and laboratory variables of the different groups were analyzed to assess the influence of viral load on the development of respiratory failure during admission. Overall, 455 sequential patients were included. The median Ct value was 28 (IQR: 24-32). One hundred and thirty patients (28.6%) had a high viral load, 175 (38.5%) an intermediate viral load and 150 (33%) a low viral load. Advanced age, male sex, presence of cardiovascular disease and laboratory markers such as lactate dehydrogenase, lymphocyte count and C-reactive protein, as well as a high viral load on admission, were predictive of respiratory failure. A Ct value < 25 was associated with a higher risk of respiratory failure during admission (OR: 2.99, 95%IC: 1.57-5.69). SARS-CoV-2 viral load, measured through the Ct value on admission, is a valuable tool to predict the development of respiratory failure in COVID-19 inpatients.

Paciente con alto riesgo cardiovascular y fibrilación auricular: papel del rivaroxabán / Patients with a high cardiovascular risk and atrial fibrillation: the role of rivaroxaban

Tradicionalmente el objetivo de la anticoagulación para el paciente con fibrilación auricular se centra principalmente en la prevención del ictus. Pero lo cierto es que estos pacientes tienen numerosas comorbilidades que también condicionan el pronóstico de manera muy importante y es necesario abordar. Esto también debería condicionar la elección del mejor tratamiento anticoagulante para el paciente en alto riesgo cardiovascular. En general, la eficacia y la seguridad de los 4 anticoagulantes orales de acción directa frente a warfarina son consistentes, independientemente de que el paciente tenga antecedentes de ictus/ accidente isquémico transitorio, diabetes mellitus, insuficiencia renal o infarto de miocardio. En el caso del rivaroxabán, varios estudios muestran que podría reducir el riesgo de infarto de miocardio y generar menos complicaciones renales que la warfarina. En un subestudio del ROCKET-AF, en pacientes con diabetes mellitus, el rivaroxabán redujo significativamente (20%) la mortalidad cardiovascular y estudios de práctica clínica muestran que el rivaroxabán no solo reduce significativamente el riesgo de eventos cardiovasculares mayores, sino también el riesgo de enfermedad arterial periférica. Como resultado de todo ello, el rivaroxabán podría considerarse como una opción preferente para la anticoagulación de los pacientes con fibrilación auricular no valvular y alto riesgo cardiovascular, por las ventajas adicionales que proporciona en esta población

Traditionally the primary aim of anticoagulation in patients with atrial fibrillation was the prevention of stroke. However, these patients actually have numerous comorbidities that also have a substantial impact on prognosis and that must be treated. These considerations should also play a role in selecting the best anticoagulant treatment for patients with a high cardiovascular risk. In general, direct oral anticoagulants have consistently been shown to have superior efficacy and safety to warfarin, irrespective of whether patients have a history of stroke, transient ischemic attack, diabetes, renal insufficiency or myocardial infarction. In particular, studies have shown that rivaroxaban is associated with a lower risk of myocardial infarction and fewer renal complications than warfarin. In a subgroup study of the ROCKET-AF trial, it was found that rivaroxaban significantly reduced cardiovascular mortality in patients with diabetes mellitus (by 20%). Moreover, studies carried out in routine clinical practice showed that the drug significantly reduces the risk of both major cardiovascular events and peripheral artery disease. As a result, rivaroxaban could be considered the preferred option for anticoagulation in patients with nonvalvular atrial fibrillation and a high cardiovascular risk, given the additional benefits it provides in this population

Impact of functional status on 6-month mortality in elderly patients with acute venous thromboembolism: results from a prospective cohort.

Functional status linked to a poor outcome in a broad spectrum of medical disorders. Barthel Activities of Daily Life Index (BADLI) is one of the most extended tools to quantify functional dependence. Whether BADLI can help to predict outcomes in elderly patients with acute venous thromboembolism (VTE) is unknown. The current study aimed to ascertain the influence of BADLI on 6-month all-cause mortality in aged patients with VTE. This is a prospective observational study. We included consecutive patients older than 75-year-old with an acute VTE between April 2015 and April 2017. We analyzed several variables as mortality predictors, including BADLI-measured functional status. Afterward, we performed a multivariate analysis, using logistic regression, to identify all-cause mortality independent predictive factors. Two hundred and two subjects were included. Thirty-five (17%) patients died in the first 6 months. The leading cause of death was cancer (59%). After multivariable logistic regression, we identified BADLI and Charlson index as independent predictors for 6-months mortality [BADLI (every decrease of 10 points) OR 1.21 95% CI (1.03-1.42) and Charlson index OR 1.71 95% CI (1.21-2.43)]. Body mass index (BMI) values were inversely related to mortality [OR 0.85 95% CI (0.75-0.95)]. In conclusion, BADLI, BMI, and Charlson index scores are independent predictive factors for 6-month all-cause mortality in old patients with VTE.

Priapism associated with zuclopenthixol.

OBJECTIVE: To present a single case of zuclopenthixol-induced priapism and a literature review. CASE SUMMARY: We report the case of a 31-year-old patient hospitalized due to behavioral alterations and treated with oral zuclopenthixol, an antipsychotic from the thioxanthene family, who developed an acute, painful erection. DISCUSSION: The occurrence of priapism in our patient was related to zuclopenthixol. This adverse reaction is reported for the first time in a patient not concomitantly treated with other drugs associated with the appearance of priapism. The capacity of zuclopenthixol to induce priapism is thought to be due to its antagonist activity on alpha-adrenergic receptors. CONCLUSIONS: Priapism is an uncommon but potentially serious adverse effect of zuclopenthixol that practitioners, as with many other antipsychotics, should be aware of.
