RESUMO

The cytokine blood profile in patients with complicated erysipelas was investigated. It was found that in patients with complications of erysipelas (gangrene, phlegmon, abscess, thrombophlebitis of the subcutaneous veins of the shin) levels of pro-inflammatory cytokines IL-1ß, TNF-α, IL-2, IL-6 in serum significantly increase and level of anti-inflammatory cytokine IL-4 increases slightly, as well as was found a significant increase in coefficients reflecting the ratio of pro-inflammatory and anti-inflammatory cytokines, which indicates the prevalence in the blood of examined patients with complications of erysipelas an anti-inflammatory properties. A more significant increase in pro-inflammatory cytokines serum levels is typical for patients with destructive forms of erysipelas - phlegmonous and gangrenous, a slight increase - for patients without purulent-necrotic component of complication (thrombophlebitis of the subcutaneous veins of the shin). In the future we plan to study pharmacological correction of shifts in cytokine blood profile with drugs with immunomodulating properties in patients with complicated erysipelas.

RESUMO

OBJECTIVE: The purpose of our study was to determine, first, if gallbladder wall striations in patients with sonographic findings suspicious for acute cholecystitis are associated with gangrenous changes and certain histologic features; and, second, if WBC count or other sonographic findings are associated with gangrenous cholecystitis. MATERIALS AND METHODS: Sixty-eight patients who underwent cholecystectomies within 48 hours of sonography comprised the study group. Sonograms and reports were reviewed for wall thickness, striations, Murphy sign, pericholecystic fluid, wall irregularity, intraluminal membranes, and luminal short-axis diameter. Medical records were reviewed for WBC count and pathology reports for the diagnosis. Histologic specimens were reviewed for pathologic changes. Statistical analyses tested for associations between nongangrenous and gangrenous cholecystitis and sonographic findings and for associations between wall striations and histologic features. RESULTS: Ten patients had gangrenous cholecystitis and 57, nongangrenous cholecystitis. One had cholesterolosis. Thirty patients had wall striations: 60% had gangrenous and 42% nongangrenous cholecystitis. There was no association with the pathology diagnosis (p = 0.32). There was no association between any histologic feature and wall striations (p ≥ 0.19). A Murphy sign was reported in 70% of patients with gangrenous cholecystitis and in 82% with nongangrenous cholecystitis; there was no association with the pathology diagnosis (p = 0.39). Wall thickness and WBC count were greater in patients with gangrenous cholecystitis than in those with nongangrenous cholecystitis (p ≤ 0.04). CONCLUSION: Gallbladder wall thickening and increased WBC counts were associated with gangrenous cholecystitis; however, there was considerable overlap between the two groups. Wall striations and a negative Murphy sign were not associated with gangrenous cholecystitis.

RESUMO

The treatment of diabetic patients with pyonecrotic lesions in the lower extremities requires prolonged reflexo-segmental balneophysiotherapy to normalize functions of the nerve centres. Curative volcanic mud solutions (15-24 g/l) enriched with organic and nonorganic biologically active compounds from volcanic deposits in Azerbaijan were used for the first time to treat such patients. Peloids were applied to the lumbar region (location of sympathetic nerve nodes) and the lower legs above and beneath the affected sites. The patients were subjected to 12-15 seances of peloidotherapy (at 40-41 degrees Celsius) each lasting 20-30 minutes. The treatment was preceded by wound sanation using the standard procedure and a course of antibiotic therapy based on individual antibiotocograms. A total of 86 daibetic patients with leg gangrene underwent rheovasographic thermovision examination that revealed enhanced blood supply to the affected extremities under the action of the applied peloids. Peloidotherapy resulted in the normalization of blood and urine glucose levels in 53 (63%) of the patients. Simultaneously, the doses of medicamentous therapy could be lowered. Wound and ulcer healing was completed in the majority of the patients (86%) by the end of balneophysiotherapy when fresh granulation tissue began to develop and signs of oedema to disappear. These patients no longer needed amputation.

RESUMO

Background: Gangrenous cholecystitis (GC) must be promptly treated for its high morbimortality. The object of our study is to identify clinical, laboratory or ultrasound factors that might us diagnose GC. Method: A Retrospective cohort study is devised including all patients admitted to Hospital de Laredo (Cantabria, Spain) between 2015 and 2017 with the diagnose of acute cholecystitis and having been operated. Patients were classified in two groups according to pathology: GC and non-GC. We compared their demographics characteristics, comorbidities, laboratory parameters and ultrasound findings. Results: A total of 115 patients were operated, of whom 32 had CG and 83 CNG. Neutrophil-to-lymphocyte ratio and C-reactive protein (CRP) showed significantly increased levels in GC group (p = 0.042) and CRP (p < 0.0001). To CRP showed an area under the ROC curve of 0.872 (95% confidence interval: 0.797-0.946). Acalculous cholecystitis was significantly associated to GC (24.1 vs. 7%; p < 0.005). In the multivariate analysis only the CPR showed as a predictive factor. A cutting point of CRP at 15.25 mg/dl, that had high sensibility (90.6%) and high negative predictive value (95%). Conclusion: CRP helped identify patients with CG to indicate early surgical intervention.


Antecedentes: La colecistitis aguda gangrenosa (CG) debe tratarse precozmente por su alto riesgo de morbimortalidad. Objetivo: Identificar factores clínicos, analíticos o ecográficos que permitan diagnosticar CG preoperatoriamente. Método: Estudio de cohorte retrospectiva en el Hospital de Laredo (Cantabria, España), entre 2015 y 2017, de pacientes con diagnóstico de colecistitis aguda que hayan sido intervenidos. Se clasificó a los pacientes en dos grupos según el diagnóstico anatomopatológico: CG y colecistitis no gangrenosa (CNG). Se compararon las características demográficas, la comorbilidad, los datos analíticos y los datos ecográficos. Resultados: Fueron operados 115 pacientes, de los cuales 32 tenían CG y 83 tenían CNG. Los pacientes con CG muestran unos valores más altos de índice de neutrófilos/linfocitos (p = 0.042) y de proteína C reactiva (PCR) (p < 0.0001). La colecistitis alitiásica se asoció con mas frecuencia a la CG (24.1 vs. 7.0%; p < 0.005). En el estudio multivariable, solo la PCR se muestra significativa. La PCR mostró un área bajo la curva ROC de 0.872, (intervalo de confianza del 95%: 0.797-0.946). Un punto de corte de PCR de 15.25 mg/dl tuvo una alta sensibilidad (90.6%) y un alto valor predictivo negativo (95%). Conclusión: La PCR ayuda a identificar a los pacientes con CG para indicar una intervención quirúrgica precoz.

RESUMO

Our aim was to see the levels of lipoprotein (a) (Lp (a)) in patients with gangrenous or non-gangrenous diabetic foot lesions. Twenty-two patients with gangrenous foot lesions, 11 with non-gangrenous foot lesions and 10 healthy subjects were included in the study. All the patients had similar glycemic control and duration of diabetes. The main outcome measure was serum Lp (a) levels in both group of patients with diabetes and healthy subjects. Diabetic patients with gangrenous foot lesions had significantly higher Lp (a) levels (83.8+/-8.3 mg/dl) than the patients with non-gangrenous foot lesions (38.3+/-5.8 mg/dl) and healthy subjects (35.6+/-4.2 mg/dl). Lp (a) levels were not significantly different in healthy subjects and in patients with non-gangrenous foot lesions. Lp (a) levels may have a pathogenetic role in the development of gangrenous foot lesions in patients with diabetes mellitus.

RESUMO

Heparin use, both prophylactically and therapeutically, is prevalent among hospitalized patients. Patients on heparin may develop a thrombocytopenia that is self-limited. Fewer patients develop a heparin-induced thrombocytopenia that can cause severe bleeding and thrombosis owing to intravascular platelet aggregation. The authors present a case report of heparin-induced thrombocytopenia in a patient who underwent aortic arch and aortic valve replacement that resulted in bilateral above-knee amputations. The patient developed limb ischemia related to heparin-associated thrombosis, but had a delay in antibody seroconversion. Early and accurate diagnosis of heparin-induced thrombocytopenia requires a high clinical suspicion and may be present despite the absence of serum antibodies.

RESUMO

AIM: The aim of this study was to study the inflammatory response to open revascularization of an ischemic leg in terms of activation of white blood cells (WBC), platelets and endothelial cells. DESIGN: prospective study. METHODS: Venous samples from 21 patients suffering critical limb ischemia (CLI) were drawn before, and 4 weeks after (20 patients) revascularization. Total WBC, differentiated WBC, and platelets were counted. Expression of CD11b/CD18 on granulocytes and monocytes and CD41 on platelets was measured by flow cytometry. Soluble endothelial markers (sICAM-1, sVCAM-1, sE-selectin and sP-selectin) were analysed with ELISA. RESULTS: WBC and granulocyte count decreased in the subgroup of patients with ulcer and gangrene but no change in activation of WBC was recorded. The endothelial marker sICAM-1 decreased while VCAM-1 increased following surgery, most evident in the subgroup with ulcers and gangrene. CONCLUSIONS: This study shows that revascularization of CLI does not significantly influence the inflammatory response in patients with rest pain only, but a limited response of down regulation was found in the ulcer/gangrene patients probably as an effect of healing ulcers.

RESUMO

The aim of the present study was to evaluate blood rheological disorders, in particular RBC enhanced aggregation, and compare changes in these parameters in patients with type 1 and 2 diabetes mellitus. For evaluation of RBC aggregability in the present study we applied the "Georgian technique", which was developed and applied for several years in our laboratory. Its advantage is that it is a direct and quantitative method. In all the investigated patients, diabetes mellitus was complicated with the foot gangrenes. The patients were divided into two groups: (a) with type 1 and (b) with type 2 diabetes mellitus. We matched the RBC aggregability indices in both groups of diabetic patients and compared the obtained results with those in the healthy control group. We found that rheological disorders were considerably pronounced. The RBC aggregability index increased by 62 percent (p < 0.001) in type 1 and by 57 percent (p < 0.001) in type 2 diabetic patients as compared to the control group. However, there were insignificant differences of the RBC aggregability changes between the two groups of patients. Therefore we conclude that blood rheological disorders are similar in both types of diabetes mellitus. The disturbed blood fluidity related to the increased RBC aggregability in the microcirculation promotes, in particular, the development of legs gangrene in both types of diabetes mellitus.

RESUMO

PURPOSE: Our aim was to establish the role of hyperbilirubinemia as a predictive parameter for the prediction of either acute, or gangrenous/perforated appendicitis as well as to compare other parameters in a similar role. METHODS: Medical files of the patients who underwent appendectomies between September 2013 and September 2014 were evaluated. Age, gender, preoperative white blood cell count (WBC), neutrophil count (NEU), neutrophil percentage (NEU%), C-reactive protein (CRP), total/direct/indirect bilirubin levels, and the postoperative histopathological findings were recorded. The Fisher's exact, Pearson's χ (2), ANOVA, and Kruskal-Wallis tests while logistic regression for multivariate analysis was performed. p < 0.05 was accepted as statistically significant. RESULTS: The study group of 162 patients consisted of 97 (60 %) men and 65 (40 %) women with a median age of 36 (18-90). Histopathological examinations revealed normal appendix in 21 (13 %) patients, non-complicated acute appendicitis in 100 (62 %), and appendiceal gangrene/perforation in 41 (25 %) patients. WBC, NEU, NEU%, and CRP levels were significantly higher in cases of acute and gangrenous/perforated appendicitis (p < 0.01). Total and direct bilirubin levels were also significantly elevated in patients with acute and gangrenous/perforated appendicitis (p < 0.01). According to multivariate analysis, elevated CRP levels were associated with 14 times, elevated total bilirubin levels were associated with five times, and elevated direct bilirubin levels were associated with 36 times greater risk for appendiceal gangrene/perforation (p < 0.01, p < 0.05, p < 0.01, respectively). CONCLUSIONS: Hyperbilirubinemia, especially with elevated direct bilirubin levels, may be considered as an important marker for the prediction of appendiceal gangrene/perforation.

RESUMO

There have been differences of opinion among authors concening in the levels of red cell 2,3-diphosphoglycerate (2,3-DPG) and nucleotides in nonacidotic diabetic patients. Our data suggest that abnormal levels of 2, 3-DPG in diabetic patients are related to the presence of vascular complications and not to the duration of the disease per sec. 2,3-DPG levels are normal in diabetic patients with no evidence of vascular complications (group A). In ambulatory patients with vascular complications (group B), significantly higher levels of 2,3-DPG are found than in normal subjects and patients in group A. In hospitalized diabetic patients with active peripheral vascular complications (group C), levels of 2,3-DPG are likewise significantly increased over those of normal subjects and patients of group A. 2,3-DPG was found to be significantly elevated in patients of group C as compared with group B. 2,3-DPG levels in venous blood from infected legs as compared with those of the peripheral venous blood were not significantly different, thereby ruling out local factors. There were no differences in the blood lactate levels in any of the group studied. The elevation of the 2,3-DPG levels may be a reflection of attempted red blood cell compensation for tissue hypoxia in the diabetic with vascular disease.

RESUMO

INTRODUCTION: Acute gangrenous appendicitis (AGA) is a common medical condition; however, the grade of appendicitis usually cannot be established preoperatively. We have attempted to identify some indicators, such as the mean platelet volume (MPV) and the platelet distribution width (PDW), to diagnose AGA. Aims. To evaluate whether or not the MPV and PDW are suitable markers to diagnose AGA. METHODS: A retrospective study of 160 patients with AGA and 160 healthy patients was undertaken. Disease diagnosis was confirmed based on the pathologic examination of surgical specimens. Patient white blood cell (WBC) count, neutrophil ratio (NR), platelet (PLT) count, MPV, PDW, and hematocrit (HCT) were analyzed. Receiver operating characteristic (ROC) curves were used to evaluate the sensitivity and specificity of these indices in AGA. Results. There were no significant differences between the AGA and control groups in age and gender. Compared to the control group, the WBC count, NR, and PDW were significantly higher (P < 0.001, resp.) and the MPV and HCT were significantly lower (P < 0.001, resp.) in the AGA group. The diagnostic specificities of the WBC count, NR, PLT count, MPV, PDW, and HCT were 86.3%, 92.5%, 58.1%, 81.7%, 83.9%, and 66.3%, respectively. Therefore, the NR had the highest diagnostic specificity for the diagnosis of AGA. CONCLUSIONS: This is the first study to assess the MPV and PDW in patients with AGA. Our present study showed that the MPV is reduced and the PDW is increased in patients with AGA; the sensitivity of PDW was superior to the MPV. A decreased MPV value and an increased PDW could serve as two markers to diagnose AGA. The NR had the highest specificity for the diagnosis of AGA.

RESUMO

Five burn patients with ecthyma gangrenosum were treated with gentamicin sulfate in an individualized aminoglycoside regimen. Dosages greater than the currently recommended 3 to 5 mg/kg/day were necessary and ranged from 15 to 30 mg/kg/day. These increased dosages cannot be used routinely but only as serum level data indicate the need. Four of the five patients survived their course of ecthyma gangrenosum. The single fatality received a much smaller dosage of gentamicin as compared with the other four patients. No ototoxic or nephrotoxic reactions were noted in any of the patients.

RESUMO

Blackfoot disease is a unique endemic and chronic progressive arteriosclerotic vascular disease in southwest area of Taiwan. In this study, we determined the plasma levels of tissue plasminogen activator (tPA), plasminogen activator inhibitor (PAI), urokinase plasminogen activator (uPA), and von Willebrand factor (vWF) antigen in Blackfoot disease patients, in comparison with normal controls from non-endemic areas and the endemic area, Putai. Blackfoot disease patients had mean tPA antigen level of 7.9 ng/ml (n = 27) which was significantly lower (p < 0.05) than both the normal controls with 11.0 ng/ml (n = 20) and the Putai normal controls with 9.7 ng/ml (n = 39). However, the mean PAI-1 antigen level in the patient group was 41.2 ng/ml (n = 28) which was significantly higher (p = 0.0001) than both the normal controls with 19.7 ng/ml (n = 23) and the Putai normal controls with 21.3 ng/ml (n = 40). Furthermore, in the patient group, a significantly lower (p < 0.005) mean uPA antigen level (2.3 ng/ml, n = 18) was noted as compared with that in the normal controls (3.2 ng/ml, n = 14). No significant difference was observed in vWF antigen level between patients and normal controls. This study suggests that a reduced capacity for fibrinolysis is associated with Blackfoot disease.

RESUMO

Platelet sensitivity to PGI2 and platelet PGI2 receptors were investigated in eight subjects with peripheral artery disease (stage IV according to Fontaine) treated for 14 consecutive days with six hour iv infusion of Iloprost (Schering, FRG) 2 ng/kg/min. Platelet studies were performed on the 1st, the 2nd, the 7th and the 14th day of therapy, immediately before infusion (between 8.00 and 9.00 a.m.), at the end and 6 and 18 hours (the following morning) after the end of the infusion. Platelet sensitivity to PGI2 was assessed by determining the PGI2 inhibitory dose 50(ID 50) on platelet aggregation induced by 5 microM ADP. PGI2 platelet receptors were investigated by a direct radioligand binding assay. PGI2 ID 50 after the infusion was significantly higher than that at baseline(p less than 0.01) and six hours later the baseline sensitivity was restored. After the six hour Iloprost iv infusion a significant reduction in the number of high affinity PGI2 platelet receptor (HAR) was observed (p less than 0.005) without any change in their affinity for the ligand. Six hours after the end of the infusion the number of the HAR was still significantly reduced (p less than 0.05). The following morning the receptor number of HAR was restored. The baseline values of PGI2 HAR, when reassessed after seven and fourteen days of treatment, were not significantly different from those recorded on the first day of therapy. These data indicate that the reduction of platelet PGI2 sensitivity following short-term Iloprost infusion is rapidly reversible and is related to a contemporary down-regulation of PGI2 platelet receptors.(ABSTRACT TRUNCATED AT 250 WORDS)

RESUMO

BACKGROUND: C-reactive protein (CRP) is a well-established, sensitive marker of systemic inflammation and the risk of cardiovascular disease. High-density lipoprotein (HDL) is an anti-atherogenic lipoprotein known to be regulated by genetic and acquired factors. METHODS: The patient was a 77-year-old Japanese woman, who was diagnosed with type 2 diabetes mellitus (DM), with a body height of 152 cm and a weight of 65 kg (body mass index 28.1 kg/m2). She suffered from diabetic foot gangrene in her right foot with high-grade fever when she visited our hospital. Her plasma glucose (PG) concentration and serum CRP were markedly elevated being 21.6 mmol/l and 370 mg/l, respectively, while her serum HDL-C concentrations were markedly low being 0.13 mmol/l. She was immediately admitted to our hospital and received intensive insulin treatment, along with intravenous-administration of antibiotics. Her general conditions were gradually improved and the high-grade fever disappeared, with concentrations of plasma PG and serum CRP being reduced, and concurrent reciprocal increase in her serum HDL-C concentrations. RESULTS: To determine the potential causative factors responsible for the drastic change in serum HDL-C concentrations, we investigated the relationship of serum HDL-C to serum CRP, serum total protein (TP) and PG. Serum CRP and PG showed inverse relationships with serum HDL-C, while serum TP concentrations showed a positive association with HDL-C. After multivariate analyses with CRP, TP and PG as independent variables and serum HDL-C as dependent variable, CRP maintained its independent association with serum HDL-C. CRP also showed inverse correlations with lipoprotein lipase (LPL) mass and cholesteryl ester transfer protein mass. CONCLUSIONS: In acute inflammation and poorly controlled diabetes, CRP is suggested to be inversely associated with serum HDL-C, independent of PG and TP.

RESUMO

A patient with end stage renal disease secondary to systemic lupus erythematosus (SLE) ultimately required amputation of the four extremities and developed mesenteric ischemia. The patient presented with widespread medial calcification involving various small to medium sized arteries, although no noticeable secondary hyperparathyroidism was observed. We speculated that SLE associated with systemic vasculitis and uremic milieu over a number of years may represent the perfect preexisting condition for calcific arteriolopathy to occur following which several factors including chronic administration of corticosteroids, photosensitivity in lupus, and significant weight loss may have contributed to acral gangrene and mesenteric ischemia.

RESUMO

To assess the effect of ticlopidine on the cutaneous circulation, 25 patients with lower limb ischemia were investigated just before and at two hours after being given a 200 mg oral dose of ticlopidine. The transcutaneous partial pressure of oxygen (PtcO2) and the skin temperature were determined at 35 limb sites and 9 chest walls sites. Both the PtcO2 and the skin temperature were significantly increased at two hours after the administration of ticlopidine (p < 0.01). The findings suggest that ticlopidine can improve the cutaneous microcirculation in patients with peripheral vascular disease.

RESUMO

We investigated the RBC aggregability in the patients with the foot diabetic gangrenes: in the venous blood samples taken from the damaged foot before its amputation, as well as from the cubital vein (the systemic circulation). The RBC aggregability was investigated with the "Georgian technique" that is sensitive and provided us with direct and quantitative data. We found that the RBC aggregability was higher by about 20%, in the blood flowing from the gangrenous tissue than in the systemic circulation. Therefore, the sources of the systemic hemorheological disorders were the primarily damaged tissues. Taking into account that the blood is uninterruptedly flowing and mixing together in the whole circulatory bed we conclude that in the systemic circulation a certain compensatory mechanism provide for a partial normalization of the blood rheological properties, since the RBC aggregability never reaches the level in the blood of the healthy people.
