RESUMO

BACKGROUND: Although data on post-coronavirus disease 2019 (COVID-19) conditions are extensive, the prognostic factors affecting symptom duration in non-hospitalized patients with COVID-19 are currently not well known. We aimed to investigate the various prognostic factors affecting symptom duration among outpatients with COVID-19. METHODS: Data were analyzed from 257 patients who were diagnosed with mild COVID-19 and visited the 'post-COVID-19 outpatient clinic' between April and December 2022 after a mandatory isolation period. The symptom duration was measured from diagnosis to symptom resolution. Laboratory and pulmonary function test results from their first visit were collected. RESULTS: The mean age of patients was 55.7 years, and the median symptom duration was 57 days. The development of post-COVID-19 conditions (> 12 weeks) were significantly correlated with not using antiviral drugs, leukocytosis (white blood cell > 10,000/µL), lower 25(OH)D3 levels, forced vital capacity (FVC) < 90% predicted, and presence of dyspnea and anxiety/depression. Additionally, in multivariable Cox regression analysis, not using antiviral drugs, lower 25(OH)D3 levels, and having dyspnea were poor prognostic factors for longer symptom duration. Particularly, vitamin D deficiency (< 20 ng/mL) and not using antivirals during the acute phase were independent poor prognostic factors for both post-COVID-19 condition and longer symptom duration. CONCLUSION: The non-use of antivirals, lower 25(OH)D3 levels, leukocytosis, FVC < 90% predicted, and the presence of dyspnea and anxiety/depression symptoms could be useful prognostic factors for predicting post-COVID-19 condition in outpatients with COVID-19. We suggest that the use of antiviral agents during the acute phase and vitamin D supplements might help reduce COVID-19 symptom duration.

RESUMO

Elucidation of the pharmacodynamic mechanisms of drugs capable of potentiating the effects of non-steroidal anti-inflammatory drugs is an important task. In this in vitro study, the ability of Traumeel S to influence the innate and acquired immunity was evaluated. Traumeel S was found to reduce activities of NADPH oxidase and neutrophil extracellular traps, as well as to evoke anti-inflammatory activity of lymphocyte subpopulations.

RESUMO

Plant extracts rich in phenolic compounds have been demonstrated to accelerate wound healing, but their use by oral route has been poorly studied. The leaves of Vitis labrusca are rich in phenolic acids and flavonoids. The goal of this study was to assess the healing properties of the oral administration of hydroalcoholic extract of V. labrusca leaves (HEVL) in a murine model. HEVL was obtained by Soxhlet and dynamic maceration, and their yield and phenolic acids and flavonoid contents were determined. For the wound healing assay, 8 mm wounds were performed on the back of 48 Wistar rats, assigned into four groups (n = 12): CTR (distilled water), HEVL100, HEVL200, and HEVL300 (HEVL at 100, 200, and 300 mg/kg, respectively). On days 7 and 14, wound closure rates were assessed, and the healing wounds were subjected to histological analysis. Soxhlet-obtained extract was selected for the wound healing assay because it provided a higher yield and phenolic acid and flavonoid contents. HEVL significantly reduced leukocytosis in the peripheral blood (p < 0.05), accelerated wound closure (p < 0.05), and improved collagenization (p < 0.05) on day 7, as well as enhanced the epidermal tissue thickness (p < 0.001) and elastic fiber deposition on day 14 (p < 0.01). Furthermore, HEVL promoted an increase in the histological grading of wound healing on both days 7 and 14 (p < 0.01). The doses of 200 and 300 mg/kg provided better results than 100 mg/Kg. Our data provide histological evidence that the oral administration of HEVL improves wound healing in rodents. Therefore, the extract can be a potential oral medicine for healing purposes.

RESUMO

West Nile virus neuroinvasive disease (WNVND) manifests with meningitis, encephalitis, and/or acute flaccid paralysis. It represents less than 1% of the clinical syndromes associated with West Nile virus (WNV) infection in immunocompetent patients. Immunosuppressive therapy is associated with increased risk of WNVND and worse prognosis. We present a patient with WNVND during therapy with rituximab, and a review of the literature for previous similar cases with the goal to describe the clinical spectrum of WNVND in patients treated specifically with rituximab. Our review indicates that the most common initial complaints are fever and altered mental status, brain magnetic resonance imaging often shows bilateral thalamic hyperintensities, and cerebrospinal analysis consistently reveals mild lymphocytic pleocytosis with elevated protein, positive WNV polymerase chain reaction, and negative WNV antibodies. Treatment is usually supportive care, with intravenous immunoglobulins (IVIG) plus corticosteroids and WNV-specific IVIG also used. The disease is usually fatal despite intervention. Our patient's presentation was very similar to prior reports, however demonstrated spontaneous improvement with supportive management only. WNVND is a rare and serious infection with poor prognosis when associated with rituximab therapy. Diagnosis is complicated by absent or delayed development of antibodies. The presence of bilateral thalamic involvement is a diagnostic clue for WNVND. There is insufficient evidence to recommend the use of corticosteroids or IVIG.

RESUMO

Peripheral blood leukocytosis and neutrophilia reflect cancer inflammation and have been proposed as prognostic immunological biomarkers in various malignancies. However, previous studies were limited by their retrospective nature and small patient numbers. Baseline peripheral blood leukocytes, neutrophils, hemoglobin, platelets, lactate dehydrogenase and carcinoembryonic antigen (CEA) were correlated with clinicopathologic characteristics, and clinical outcome in 1236 patients with rectal cancer treated with 5-FU-based preoperative chemoradiotherapy (CRT) alone or with oxaliplatin followed by surgery and adjuvant chemotherapy within the CAO/ARO/AIO-04 randomized phase 3 trial. Multivariable analyses were performed using Cox regression models. After a median follow-up of 50 months, baseline leukocytosis remained an independent adverse prognostic factor for disease-free survival (DFS; HR 1.457; 95% CI 1.163-1.825; p = 0.001), distant metastasis (HR 1.696; 95% CI 1.266-2.273; p < 0.001) and overall survival (OS; HR 1.716; 95% CI 1.264-2.329; p = 0.001) in multivariable analysis. Similar significant findings were observed for neutrophilia and high CEA levels. Conversely, treatment-induced leukopenia correlated with favorable DFS (p = 0.037), distant metastasis (p = 0.028) and OS (p = 0.012). Intriguingly, addition of oxaliplatin to 5-FU CRT resulted in a significant DFS improvement only in patients with neutrophilia and leukocytosis (p = 0.028 and p = 0.002). Our findings have important clinical implications and provide high-level evidence on the adverse prognostic role of leukocytes and neutrophils, and the impact of chemotherapy in the context of these biomarkers. These data could help guide patient stratification and should be further validated within prospective studies.

RESUMO

Zizyphus jujuba Mill, a famous oriental traditional medicine, has been reported to exhibit diverse activities in biological systems including the respiratory system. However, a little information is available on its antiasthmatic activity. Jujuboside B (JB) is a natural saponin and one of the active constituent of fruits of Zizyphus jujuba. In the present investigation, JB was isolated from ethanolic extracts of fruits of Zizyphus jujuba (EZJF). EZJF and JB were then evaluated for anti-asthmatic activity using various screening methods. JB was additionally evaluated using ovalbumin (OVA) -induced allergic asthma in mice. Results obtained in the present study showed that EZJF and JB significantly inhibited clonidine-induced catalepsy, milk-induced leucocytosis and eosinophilia, clonidine-induced mast cell degranulation, and passive paw anaphylaxis. The number of inflammatory cells in bronchoalveolar lavage (BAL) fluid was considerably lowered and the severity of pulmonary inflammation was alleviated in the mice pretreated with JB. The high-level expression of T-helper type 2 (TH2) cytokines was markedly reduced in the serum, BAL fluid, and lung homogenates. Thus EZJF and JB showed potent anti-asthmatic activity. Hence EZJF and JB possess a potential role in the treatment of asthma.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Seed kernel of the plant Ceasalpinia bonducella Linn (Caesalpiniacaeae) are used for the treatment of asthma in folk medicine and ancient books. AIM OF STUDY: To assess the pharmacological efficacy of the plant in asthma and to confine and describe the synthetic constituents from the seeds that are in charge of the action. MATERIAL AND METHODS: The viability of petroleum ether, ethanol extract and ethyl acetate fraction from ethanol extract of C. bonducella seeds were screened for the treatment of asthma by various methods viz. effect of test drug on clonidine and haloperidol induced catalepsy, milk-induced leukocytosis and eosinophilia, mast cell stabilizing activity in mice and studies on smooth muscle preparation of guinea pig ileum (in-vitro). Column chromatography of active extract was done to pinpoint the active compound followed by structure elucidation by FTIR, GCMS and NMR spectroscopic methods. RESULTS: Ethyl acetate fraction from ethanol extract of C. bonducella seeds exhibited antihistaminic activity at the dose of 50 and 100 mg/kg, inhibited clonidine-induced catalepsy but not haloperidol-induced catalepsy. Ethyl acetate fraction from ethanol extract significantly inhibited increased leukocyte and eosinophil count due to milk allergen and showed maximum protection against mast cell degranulation by clonidine. The results of guinea pig ileum indicated that the compound 2 methyl, 1 hexadecanol isolated from ethyl acetate fraction of ethanol extract relaxed significantly the ileum muscle strips pre-contracted by which suggests the involvement of ß2-agonists on the relaxation of the tissue. All the results are dose dependent. Active ethyl acetate fraction from ethanol extract showed presence of anti-asthmatic compound, 2-methyl, 1-hexadecanol. CONCLUSION: The ethyl acetate fraction from ethanol extract of seeds of the plant C. bonducella can inhibit parameters linked to asthma disease.

RESUMO

BACKGROUND: Stercoral colitis is a rare inflammatory process involving the colonic wall secondary to fecal impaction with high morbidity and mortality; especially if complicated with ischemic colitis, stercoral ulcer formation and subsequent perforation. There are several case reports published on abdominal perforation resulting from stercoral colitis. However, stercoral colitis complicated by ischemic colitis is rare. The purpose of this case report is to describe the potential challenges in the diagnosis and management of stercoral colitis with ischemic colitis. CASE PRESENTATION: An 87 years old male with history of chronic constipation presents with severe abdominal pain to the emergency department. The patient was hemodynamically stable. On physical examination, the abdomen was mildly distended with moderate tenderness. Lab work was significant for leukocytosis and lactic acidosis. Abdominal CT scan revealed large amount of retained stool in the colon, bowel wall thickening and infiltration of peri-colonic fat, which were suggestive for stercoral colitis. Patient was started on IV fluids and antibiotics. He was given an enema, followed by laxative and manual disimpaction of stool. Colonoscopy was performed and biopsies were obtained. Tissue biopsy was significant for focal active colitis with regenerative glandular changes and neural hyperplasia. CONCLUSION: Elevated lactic acid level secondary to ischemia of the bowel wall with CT scan findings aid in establishing the diagnosis of stercoral colitis complicated with ischemic colitis. Urgent treatment with laxatives and fecal disimpaction is indicated to prevent perforation and peritonitis.

RESUMO

OBJECTIVE: We aimed to compare the kinetics of white blood cell (WBC) and explore predictive factors of leukocytosis in non-high-risk acute promyelocytic leukemia (APL), with oral arsenic plus all-trans retinoic acid (ATRA) or intravenous arsenic trioxide (ATO) plus ATRA as a first-line treatment. METHODS: The absolute count, doubling time and peak time of WBC were analyzed in 64 newly diagnosed non-high-risk APL patients who were treated with different induction regimens containing either oral Realgar-indigo naturalis formula (RIF) (n=35) or ATO (n=29). The end points were the dynamic changes of the WBC counts during induction. The time points started at day 1 and were selected over 3-day intervals for 28days. RESULTS: Among the 64 included patients, the median initial and peak WBC counts were 1.78×109/L (range 0.31-9.89) and 12.16×109/L (range 1.56-80.01), respectively. The incidence of differentiation syndrome was 9.38%. The dynamic changes in leukocytosis showed a single peak wave in all the patients, and the median time to peak was 10 (range 2-26) days. A higher WBC count was observed in the RIF group than in the ATO group after 10days of treatment (9.22×109/L vs. 4.10×109/L, p=0.015). Patients with the peak WBC count >10×109/L had a shorter WBC doubling time compared to patients with a lower peak WBC (RIF group 4days vs. 7days, p=0.001; ATO group 4.5days vs. 23days, p=0.002). Univariate and multivariable analyses showed that the doubling time of WBC is an independent factor for the peak WBC count. CONCLUSION: Different kinetics of WBC proliferation were observed during induction with oral arsenic plus ATRA and ATO plus ATRA. The doubling time of WBC is an important independent factor for predicting the peak WBC count.

RESUMO

Ischemia/reperfusion injury (IRI) contributes to morbidity and mortality after cardiovascular surgery requiring cardiopulmonary bypass (CPB) and deep hypothermic circulatory arrest (DHCA). Multi-organ damage is associated with substantial decreases of blood selenium (Se) levels in patients undergoing cardiac surgery with CPB. We compared the influence of a dietary surplus of Se and pretreatment with ebselen, a mimic of the selenoenzyme glutathione peroxidase, on IRI-induced tissue damage and inflammation. Male Wistar rats were fed either a Se-adequate diet containing 0.3 ppm Se or supplemented with 1 ppm Se (as sodium selenite) for 5 weeks. Two other groups of Se-adequate rats received intraperitoneal injection of ebselen (30 mg/kg) or DMSO (solvent control) before surgery. The animals were connected to a heart-lung-machine and underwent 45 min of global ischemia during circulatory arrest at 16 °C, followed by re-warming and reperfusion. Selenite and ebselen suppressed IRI-induced leukocytosis and the increase in plasma levels of tissue damage markers (AST, ALT, LDH, troponin) during surgery but did not prevent the induction of proinflammatory cytokines (IL-6, TNF-α). Both Se compounds affected phosphorylation and expression of proteins related to stress response and inflammation: Ebselen increased phosphorylation of STAT3 transcription factor in the heart and decreased phosphorylation of ERK1/2 MAP kinases in the lungs. Selenite decreased ERK1/2 phosphorylation and HSP-70 expression in the heart. Pretreatment with selenite or ebselen protected against acute IRI-induced tissue damage during CPB and DHCA. Potential implications of their different actions with regard to molecular stress markers on the recovery after surgery represent promising targets for further investigation.

RESUMO

CONTEXT: The flower bud of Tussilago farfara L. (Compositae) (FTF) is one of the traditional Chinese medicinal herbs used to treat cough, phlegm, bronchitic, and asthmatic conditions. OBJECTIVE: The objective of this study is to isolate four caffeoylquinic acids from the ethyl acetate extract (EtE) of FTF and to evaluate their antitussive, expectorant, and anti-inflammatory activities. MATERIALS AND METHODS: The structures of compounds 1-4 isolated from EtE were determined by spectral analysis. Mice were orally treated with these compounds and their mixture (in a ratio of 5:28:41:26 as in EtE) at doses of 10 and 20 mg/kg once daily for 3 d. The antitussive and expectorant activities were evaluated separately with the ammonia liquor-induced model and the phenol red secretion model. The anti-inflammation activity was evaluated using leukocyte count in the bronchoalveolar lavage fluid after ammonia liquor-induced acute airway inflammation. RESULTS: The four compounds were identified as chlorogenic acid (1), 3,5-dicaffeoylquinic acid (2), 3,4-dicaffeoylquinic acid (3), and 4,5-dicaffeoylquinic acid (4). All compounds, especially compound 4 (58.0% inhibition in cough frequency), showed a significant antitussive effect. However, the mixture was the most effective to inhibit the cough frequency by 61.7%. All compounds also showed a significant expectorant effect, while compound 2 was the most potent to enhance the phenol red secretion by 35.7%. All compounds significantly alleviated inflammation, but compound 4 showed the strongest effect to inhibit the leukocytosis by 49.7%. DISCUSSION AND CONCLUSION: The caffeoylquinic acids and their mixture, exhibiting significant antitussive, expectorant, and anti-inflammatory effects, could be considered as the main effective ingredients of FTF, and they may act in a collective and synergistic way.

RESUMO

This study focuses on investigating the possible protective effect of sodium selenite (Na2SeO3) and/or vitamin E against mercuric chloride (HgCl2)-induced hepatotoxicity in rat. Male rats were given HgCl2 (1 mg/kg body weight (bw)) and HgCl2 plus Na2SeO3 (0.25 mg/kg bw) and/or vitamin E (100 mg/kg bw) daily via gavage for 4 weeks. HgCl2-treated groups had significantly higher white blood cell and thrombocyte counts than the control group. Serum activities of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, γ-glutamyl-transferase, and lactate dehydrogenase significantly increased and serum levels of total protein, albumin, triglyceride, total cholesterol, and low-density lipoprotein cholesterol significantly decreased in the HgCl2-treated groups compared with control group. Malondialdehyde level significantly increased and superoxide dismutase, catalase, and glutathione peroxidase activities decreased in liver tissue of HgCl2-treated rats. Also, HgCl2 exposure resulted in histopathological changes. Supplementation of Na2SeO3 and/or vitamin E provided partial protection in hematological and biochemical parameters that were altered by HgCl2 As a result, Na2SeO3 and/or vitamin E significantly reduced HgCl2-induced hepatotoxicity, but not protected completely.

RESUMO

Japanese encephalitis (JE) is a potentially serious form of viral encephalitis with varied clinicoradiological manifestations. We report the case of a 19-year-old girl admitted with headache, vomiting and altered sensorium in the absence of fever, whose cerebrospinal fluid analysis showed lymphocytic pleocytosis with significant protein content and positive serum IgM JE antibodies. MRI with venography revealed bilateral thalamic haemorrhage and cerebral venous sinus thrombosis. Although thalamic hypodensities are a well-described feature, thalamic haemorrhage and cerebral venous thrombosis are distinctly rare in JE. This report highlights the role of imaging in cases of encephalitis in general and JE in particular, in the early detection of uncommon manifestations that may complicate these diseases.

RESUMO

Traumeel (Tr14) is a natural, combination drug, which has been shown to modulate inflammation at the cytokine level. This study aimed to investigate potential effects of Tr14 on the exercise-induced immune response. In a double-blind, randomized, controlled trial, healthy, untrained male subjects received either Tr14 (n = 40) or placebo (n = 40) for 24 h after a strenuous experimental exercise trial on a bicycle (60 min at 80%VO2 max). A range of antigen-stimulated cytokines (in vitro), white blood cell count, lymphocyte activation and apoptosis markers, and indicators of muscle damage were assessed up to 24 h following exercise. The area under the curve with respect to the increase (AUCI ) was compared between both groups. The Tr14 group showed a reduced exercise-induced leukocytosis and neutrocytosis (P < 0.01 for both), a higher AUCI score of antigen-stimulated IL-1ß and IL-1α (absolute and per monocyte, all P < 0.05), a lower AUCI score of antigen-stimulated GM-CSF (P < 0.05) and by trend a lower AUCI score of antigen-stimulated IL-2 and IL-4 as well as a higher AUCI score of antigen-stimulated IL-6 (all P < 0.1). Tr14 might promote differentiated effects on the exercise-induced immune response by (a) decreasing the inflammatory response of the innate immune system; and (b) augmenting the pro-inflammatory cytokine response.

RESUMO

RESUMO Este estudo teve como objetivo avaliar os efeitos da própolis sobre os perfis leucocitário e protéico de camundongos e sobre o tempo de fechamento de lesões de pele confeccionadas experimentalmente, limpas e infectadas com Staphylococcus aureus. No primeiro, foram utilizados 48 animais divididos em quatro grupos, sendo um tratado com solução hidroalcóolica pura e três tratados com própolis a 10%, nas dosagens de 20 mg, 40 mg e 80 mg por animal de 25 gramas de peso, em única aplicação intraperitoneal. Foram coletadas amostras de sangue no segundo, 10º, 18º e 26º dias após o tratamento para realização de leucograma, proteinograma e fracionamento eletroforético das proteínas. Na avaliação da atividade cicatrizante, também foram utilizados 48 camundongos divididos em seis grupos, nos quais realizou-se a confecção cirúrgica de feridas na dimensão de 1cm2, após anestesia dissociativa. Dois grupos serviram como controle para feridas limpas e infectadas. Dois grupos de feridas infectadas por S. aureuse dois grupos de feridas limpas foram tratados com própolis a 5% e 10%, sendo a escolha destas concentrações baseada em um estudo piloto realizado. Os resultados mostraram que o tratamento com própolis influencia o leucograma e o proteinograma, de forma dose-dependente, sendo que a maior dose utilizada desencadeou leucocitose com linfocitose e aumento de proteínas da fração gamaglobulínica, no 10º dia após o início do tratamento. Também mostraram que a concentração da solução influenciou o tempo de cicatrização das feridas infectadas, ocorrendo em menor tempo no grupo tratado com a solução a 5%.


ABSTRACT This study aimed to evaluate the propolis effects on both the leukocyte and protein profiles of mice and on the closing time of skin lesions made experimentally, clean and infected with Staphylococcus aureus. The first 48 animals were divided into four groups, one treated with pure alcohol solution and three treated with propolis 10% at dosages of 20 mg, 40 mg and 80 mg per 25 g of animal weight in an intraperitoneal single application . Blood samples in the second, and then 10º, 18º and 26º days after treatment were collected in order to perform WBC, proteins and electrophoretic fractionation of proteins. Regarding the healing activity, also 48 mice divided into six groups were used, in whom surgical wounds in the size of 1cm2 were purposely inflicted , after the dissociative anesthesia were applied . Two groups served as control ones, for clean and infected wounds. Two groups of S. aureus with infected wounds and two groups with clean sores were treated with 5% and 10 % propolis, being this concentration choice based on a pilot study previously performed. The results showed that treatment with propolis influences leukocyte and protein concentrations in a dose- dependent manner, with the highest dose triggering leukocytosis with lymphocytosis and increasing the protein fraction of gamaglobulínica, on the 10th day after the start of treatment. It also indicated that the concentration of the solution influence the time of healing of infected wounds, since the process on the group treated with 5% solution happened faster.

RESUMO

BACKGROUND AND AIMS: Diverticulitis is often diagnosed in outpatients, yet little evidence exists on diagnostic evidence and demographic/clinical features in various practice settings. We assessed variation in clinical characteristics and diagnostic evidence in inpatients, outpatients, and emergency department cases and effects of demographic and clinical variables on presentation features. METHODS: In a retrospective cohort study of 1749 patients in an integrated health care system, we compared presenting features and computed tomography findings by practice setting and assessed independent effects of demographic and clinical factors on presenting features. RESULTS: Inpatients were older and more often underweight/normal weight and lacked a diverticulitis past history and had more comorbidities than other patients. Outpatients were most often Hispanic/Latino. The classical triad (abdominal pain, fever, leukocytosis) occurred in 78 (38.6%) inpatients, 29 (5.2%) outpatients and 34 (10.7%) emergency department cases. Computed tomography was performed on 196 (94.4%) inpatients, 110 (9.2%) outpatients and 296 (87.6%) emergency department cases and was diagnostic in 153 (78.6%) inpatients, 62 (56.4%) outpatients and 243 (82.1%) emergency department cases. Multiple variables affected presenting features. Notably, female sex had lower odds for the presence of the triad features (odds ratio [95% CI], 0.65 [0.45-0.94], P<0.05) and increased odds of vomiting (1.78 [1.26-2.53], P<0.01). Patients in age group 56 to 65 and 66 or older had decreased odds of fever (0.67 [0.46-0.98], P<0.05) and 0.46 [0.26-0.81], P<0.01), respectively, while > / =1 co-morbidity increased the odds of observing the triad (1.88 [1.26-2.81], P<0.01). CONCLUSION: There was little objective evidence for physician-diagnosed diverticulitis in most outpatients. Demographic and clinical characteristics vary among settings and independently affect presenting features.

RESUMO

Objetivo: Demostrar que la colecistostomía es un procedimiento quirúrgico seguro y aplicable actualmente. Método: Descripción de dos casos con diagnóstico de colecistitis aguda y alto riesgo quirúrgico, a quienes se les realizó la colecistostomía. Una fue realizada con anestesia local en el área de la emergencia y la otra tuvo que realizarse en quirófano, en vista de fallas técnicas de las máquinas anestésicas, ambos casos tratados en el Hospital General del Oeste "Dr. José Gregorio Hernández" los Magallanes de Catia. Servicio de Cirugía I. Resultados: Ambos pacientes eran mayores de 60 años. Entre los resultados paraclínicos destaca la leucocitosis con desviación a la izquierda. Los pacientes fueron catalogados como ASA IV y ASA III. Ambos recibieron antibióticos endovenosos desde su ingreso, sin mejoría clínica ni paraclínica. Se realizó la colecistostomía quirúrgica, logrando conseguir la estabilidad hemodinámica. Posteriormente, fueron llevados a trata-miento quirúrgico definitivo de manera electiva, lográndose una evolución satisfactoria. Conclusión: En pacientes de edad avanzada con comorbilidades que condicionen un alto riesgo anestésico y quirúrgico en el contexto de un cuadro de colecistitis aguda sin respuesta al tratamiento médico, la colecistostomía proporciona una excelente alternativa quirúrgica temporal, para lograr la estabilidad hemodinámica y así disminuir la morbimortalidad(AU)


Objective: To demonstrate that cholecystostomy is a safe surgical procedure and applicable today. Method: Description of two cases with a diagnosis of acute cholecystitis and high surgical risk, who held the cholecystostomy. One was carried out under local anaesthesia in the area of the emergency and the other had to be done at operating room, in view of technical failures of the anaesthetic equipment, study done at Hospital General del Oeste "Dr. Jose Gregorio Hernandez" Magallanes de Catia, Caracas, Surgery service I. Results: Both patients were over the age of 60, the paraclinical findings include leukocytosis with left shift. The patients were classified as ASA III and IV. Both received intravenous antibiotics from your income, without clinical or paraclinical improvement. He was the surgical cholecystostomy, managing to achieve hemodynamic stability. Subsequently, were taken to definitive surgical treatment of elective way, with a satisfactory evolution. Conclusion: In older patients with comorbidities that determine high risk surgical and anesthetic in the context of acute cholecystitis with no response to medical treatment, the cholecystostomy provides an excellent temporary surgical alternative, to achieve hemodynamic stability and thus reduce morbidity and mortality(AU)
