El objetivo principal del estudio fue conocer la frecuencia de hiperCKemia en dos hospitales de la Ciudad de Córdoba y sus principales causas. Metodología: Estudio analítico retrospectivo en dos hospitales de la ciudad de Córdoba en Argentina, donde se identificaron todos los pacientes mayores de 18 años que presentaron valores de CK mayores a 285 U/L en al menos 2 oportunidades en un período entre 1 y 4 semanas, entre los años 2015 y 2017. Resultados: Se identificaron 254 pacientes con hiperCKemia, la mayoría eran de sexo masculino (n=181, 71.3%) y su mediana de edad fue 65 años (rango intercuartil 25-75%=50-73 años). Las principales causas de hiperCKemia fueron la miopatía isquémica en 99 (39%) pacientes y las miopatías inducidas por drogas en 45 (17.7%), ...

Se comparó RCV estimado por dichas ecuaciones, con la ocurrencia de eventos cardiovasculares (ECV) en una población de pacientes sin enfermedad cardiovascular de un hospital argentino. Se incluyeron aleatoriamente adultos entre 40 y 70 años, excluyéndose quienes al momento del enrolamiento presentaban historia de ECV mayor, cáncer activo, o tratamiento hipolipemiante. Se calculó RCV a 10 años al momento de inclusión, utilizando ecuaciones de Framingham 2008, SCORE (para poblaciones de bajo y alto riesgo), ATP III, Organización mundial de la salud-región América B (OMS-B) y Ecuación de Cohorte Agrupada (ECA). El fin de seguimiento fue 10 años ± 6 meses, ocurrencia de infarto de miocardio fatal o muerte por cualquier causa. Se utilizaron curvas ROC para evaluar discriminación (ABC > 0.75 buena discriminación). La calibración se evaluó mediante chi-cuadrado de Hosmer Lemeshow (Chi > 20 o p < 0.05 pobre calibración). Incluimos 606 pacientes, 366 mujeres, edad promedio 56.7 ± 8.4 años. Se observaron 10 (1.7%) muertes de causa no cardiovascular, 5 (0.8%) causa cardiovascular. Se registraron 58 (9.8%) ECV no fatales. Hubo aceptable discriminación para ecuaciones de Framingham, ATP-III y ECA. La calibración global solo fue buena con las ecuaciones de ATP-III y ECA. La frecuencia observada de ECV fue baja, y hubo sobreestimación de RCV con todas las ecuaciones. Sin embargo, se podría sugerir la aplicación de las ecuaciones de ATP-III o ECA en esta población.

The objectives of the study were to evaluate the incidence, risk factors (considering demographic characteristics, comorbidities, initial clinical presentation and associated complications) and impact of AKI in subjects hospitalized for COVID-19 in two third-level hospitals in Córdoba, Argentina. A retrospective cohort study was conducted. We included 448 adults who were consecutively hospitalized for COVID-19 between March 3 and October 31, 2020 and were followed throughout the hospitalization. The incidence of AKI was 19% (n = 85; stage I = 43, stage II = 17, and stage III = 25, 18 required renal replacement therapy). In the multivariate analysis, the variables that were independently associated with AKI were: age (for every 10 years, adjusted odd ratio [95%CI] = 1.30 [1.04-1.63], p = 0.022), history of chronic kidney disease -CKD- (9.92 [4.52-21.77], p < 0.001), blood neutrophil count at admission -BNCA- (for every increase of 1000 BNCA, 1.09 [1.01-1.18], p = 0.037) and requirement for mechanical ventilation -MV- (6.69 [2.24-19.90], p = 0.001). AKI was associated with longer hospitalization, higher admission (63.5 vs. 29.7%; p < 0.001) and longer stay in the intensive care unit, a positive association with respiratory bacterial superinfection, sepsis, respiratory distress syndrome, MV requirement and mortality (mortality without AK I = 12.4% vs with AKI = 47.1%; stage I = 26%, stage II = 41% and stage III = 88%; p < 0.001). AKI was independently associated with higher mortality (3.32 [1.6-6.9], p = 0.001). In conclusion, the incidence of AKI in adults hospitalized for COVID-19 was 19% and had a clear impact on morbidity and mortality. The independent risk factors for AKI were: Age, CKD, BNCA and MV.

Un elemento característico de esta entidad es la formación recurrente de ampollas en piel y mucosas ante traumatismos mínimos, con posterior cicatrización. Los pacientes con EBRD frecuentemente desarrollan enfermedad renal crónica y requieren de terapia de reemplazo renal, constituyendo una importante causa de morbilidad y mortalidad en estos pacientes. El rol del trasplante renal es poco conocido en este tipo de pacientes.Se presenta el caso de un paciente con enfermedad renal terminal y EBDR que es tratado con trasplante renal y su seguimiento a lo largo de un período de 83 meses luego del trasplante. Durante dicho período se observó una baja frecuencia de intercurrencias infecciosas, así como la ausencia de desarrollo de neopla...

To determine epidemiological, microbiological and clinical features of community (CA-BI) and nosocomial bloodstream infections (N-BI). Bacteremia and fungemia events were retrospectively analyzed in two third-level hospitals between April 2009 and August 2013. We identified 1150 events of bloodstream infections, 53.2% were CA-BI. Gram negative microorganisms were isolated in 61%. The most frequent pathogens were Escherichia coli in CA-BI and Klebsiella pneumoniae in N-BI. Staphylococcus aureus was the most frequent gram positive organism. The main comorbidities were renal disease (39%) and malignancy (38%). There were 26.8% of primary bloodstream infections, and the main infection foci included respiratory (17.04%) and urinary tract (16.86%). A high percentage of gram-negative bacteria of CA-BI and N-BI were resistance to ampicillin sulbactam (40.2% and 57.5%), cephalothin (36.7% and 46.8%), trimethoprim-s...

The aim of this study was to determine the relative frequency, clinical presentation, antimicrobial susceptibility profile, and risk factors associated with GBS bacteremia in non-pregnant adult patients. We conducted a retrospective analysis of blood cultures performed in two hospitals between the years 2009-2013. From 1110 bacteremia episodes, 13 were caused by GBS, all of which were susceptible to ampicillin. GBS bacteremia was more frequent in females and in patients older than 60 years of age. The most frequent comorbidities were chronic kidney disease, cardiac failure and neoplasia. History of appendectomy was detected in 53.8% of the patients, being the most relevant comorbidity for GBS bacteremia in the multivariate analysis (OR 4.13, p=0.012). The main presentations were primary bacteremia and soft tissue infection. GBS bacteremia was infrequent in our institution, and...

A retrospective study was performed in two hospitals aimed to evaluate characteristics of BI episodes occurred in adult patients with hematologic (HN) and solid (SN) neoplasia other than non-melanoma skin cancers in the period 2009-2016. A total of 467 episodes of bacteremia and 16 of fungemia were identified. A total of 200 (41.4%) bacteremias occurred in patients with HN and 283 (58.6%) in patients with SN. The most frequent SN and HN were colon cancer (18.7%) and non-Hodgkin lymphoma (27%), respectively. The main risk factors for BI were a previous surgical procedure in SN and chemotherapy in the previous 30 days and use of central venous catheter in HN. Infections were mainly acquired in the hospital environment and the most frequent presentation was bacteremia without focus, mostly in HN (38% vs. 20.8%, p < 0.001). Gram negative bacilli (GNB) were isolated in 336 (69.5%) episode...

We aimed at determining the frequency and type of infections that occur in renal transplant recipients during the early (0-1 month), intermediate (1-6 months) and late (6-12 months) post-transplant period and analyzing the risk factors for infection. To this aim, we conducted a retrospective cohort study on 1-year post-transplant follow-up in two third-level university hospitals in Cordoba city. All consecutive recipients of renal transplants performed between 2009 and 2015 were included, except those with multiple solid organ transplantation and pediatric patients. We included 375 recipients, of which 235 (62.7%) had at least one episode of infection during follow-up. There were 504 episodes of infection, of which 131 (26%) occurred in the early, 272 (53.9%) in the intermediate, and 101 (20.1%) in the late post-transplant period. The most frequent infections in all periods were caused by bacteria (mainly urinary tract inf...

The central nervous system (CNS) and skin are the organs most commonly affected. We describe the case of a 64-year-old male who presented to the emergency department (ED) complaining of asthenia and bilateral lower extremity edema that progressed rapidly to anasarca. On presentation, laboratory results were significant for elevated erythrocyte sedimentation rate (ESR) and lactate dehydrogenase (LDH) levels. A skin biopsywas performed, which revealed occlusion of blood vessels by atypical immunophenotype B lymphoid cells within the dermis and subcutaneous tissue. The immuno-histochemistry was consistent with IVLB CL. IVLBCL is an aggressive and rapidly fatal neoplasia with varied and nonspecific clinical manifestations, hence, a diagnostic challenge. This case shows an unusual presentation with ...

The objective was determinate the epidemiologic and microbiologic features of the BI in neutropenic patients with solid neoplasm (SN) and hematologic neoplasm (HN). Retrospective study in two third level hospitals between 2009 and 2016. They were included all the patients older than 18 years-old with active oncologic disease and neutropenia, who had BI. Patients with dermatologic cancer other than melanoma where excluded. A total of 143 BI in neutropenic were observed, of which 80.4% occurred in HN. Around 97.9% of the patients had a high-risk neutropenia without differences between both groups. The most frequent site of BI was primary bacteremia (46.9%) and catheter-associated infection (21%), without significant differences between the two groups. The gram negatives bacilli (GNB) predominated over the gram positive cocci (GPC) and they r...

In this condition, individuals carry the mutation of the HbS gene in one of the two beta-globin genes. In general, SCT does not present with the typical manifestations of sickle cell anemia. However, under certain circumstances, some clinical characteristics of the disease may develop. METHODS We discussed the case of a 39-Year old man who presented with persistent abdominal pain of unknown origin after traveling to a high-altitude place. He underwent laparotomy without a definite diagnosis. After that, the patient developed signs of splenic infarction and pulmonary thromboembolism that were confirmed by computed tomography. RESULTS A sickling test was positive, and a hemoglobin electrophoresis revealed an abnormal fraction at the HbS level. In this context a diagnosis of SCT was made. Additional, tests revealed a strongly positive lupus anticoagulant. CONCLUSION SCT presentatio...

The central nervous system (CNS) and skin are the organs most commonly affected. We describe the case of a 64-year-old male who presented to the emergency department (ED) complaining of asthenia and bilateral lower extremity edema that progressed rapidly to anasarca. On presentation, laboratory results were significant for elevated erythrocyte sedimentation rate (ESR) and lactate dehydrogenase (LDH) levels. A skin biopsywas performed, which revealed occlusion of blood vessels by atypical immunophenotype B lymphoid cells within the dermis and subcutaneous tissue. The immuno-histochemistry was consistent with IVLB CL. IVLBCL is an aggressive and rapidly fatal neoplasia with varied and nonspecific clinical manifestations, hence, a diagnostic challenge.

The objective was determinate the epidemiologic and microbiologic features of the BI in neutropenic patients with solid neoplasm (SN) and hematologic neoplasm (HN). Retrospective study in two third level hospitals between 2009 and 2016. They were included all the patients older than 18 years-old with active oncologic disease and neutropenia, who had BI. Patients with dermatologic cancer other than melanoma where excluded. A total of 143 BI in neutropenic were observed, of which 80.4% occurred in HN. Around 97.9% of the patients had a high-risk neutropenia without differences between both groups. The most frequent site of BI was primary bacteremia (46.9%) and catheter-associated infection (21%), without significant differences between the two groups. The gram negatives bacilli (GNB) predominated over the gram positive cocci (GPC) and they r...

The central nervous system (CNS) and skin are the organs most commonly affected. We describe the case of a 64-year-old male who presented to the emergency department (ED) complaining of asthenia and bilateral lower extremity edema that progressed rapidly to anasarca. On presentation, laboratory results were significant for elevated erythrocyte sedimentation rate (ESR) and lactate dehydrogenase (LDH) levels. A skin biopsywas performed, which revealed occlusion of blood vessels by atypical immunophenotype B lymphoid cells within the dermis and subcutaneous tissue. The immuno-histochemistry was consistent with IVLB CL. IVLBCL is an aggressive and rapidly fatal neoplasia with varied and nonspecific clinical manifestations, hence, a diagnostic challenge.

A retrospective study was performed in two hospitals aimed to evaluate characteristics of BI episodes occurred in adult patients with hematologic (HN) and solid (SN) neoplasia other than non-melanoma skin cancers in the period 2009-2016. A total of 467 episodes of bacteremia and 16 of fungemia were identified. A total of 200 (41.4%) bacteremias occurred in patients with HN and 283 (58.6%) in patients with SN. The most frequent SN and HN were colon cancer (18.7%) and non-Hodgkin lymphoma (27%), respectively. The main risk factors for BI were a previous surgical procedure in SN and chemotherapy in the previous 30 days and use of central venous catheter in HN. Infections were mainly acquired in the hospital environment and the most frequent presentation was bacteremia without focus, mostly in HN (38% vs. 20.8%, p < 0.001). Gram negative bacilli (GNB) were isolated in 336 (69.5%) episode...

The objectives of the study were to evaluate the incidence, risk factors and impact of AKI in subjects hospitalized for COVID-19 in two third- level hospitals in Cordoba, Argentina. A retrospective cohort study was conducted. 448 adults who were consecutively hospitalized for COVID-19 between March and the end of October 2020 at Hospital Privado Universitario de Cordoba and Hospital Raul Angel Ferreyra were included. The incidence of AKI was 19% (n=85). 50.6% presented AKI stage 1 (n=43), 20% stage 2 (n=17) and 29.4% stage 3 (n=25, of which 18 required renal replacement therapy). In the multivariate analysis, the variables that were independently associated with AKI were: age (adjusted Odd ratio -aOR- =1.30, 95%CI=1.04-1.63, p=0.022), history of chronic kidney disease (aOR=9.92, 95%CI=4.52-21.77, p<0.001), blood neutrophil...

We aimed at determining the frequency and type of infections that occur in renal transplant recipients during the early (0-1 month), intermediate (1-6 months) and late (6-12 months) post-transplant period and analyzing the risk factors for infection. To this aim, we conducted a retrospective cohort study on 1-year post-transplant follow-up in two third-level university hospitals in Cordoba city. All consecutive recipients of renal transplants performed between 2009 and 2015 were included, except those with multiple solid organ transplantation and pediatric patients. We included 375 recipients, of which 235 (62.7%) had at least one episode of infection during follow-up. There were 504 episodes of infection, of which 131 (26%) occurred in the early, 272 (53.9%) in the intermediate, and 101 (20.1%) in the late post-transplant period. The most frequent infections in all periods were caused by bacteria (mainly urinary tract inf...

In this condition, individuals carry the mutation of the HbS gene in one of the two beta-globin genes. In general, SCT does not present with the typical manifestations of sickle cell anemia. However, under certain circumstances, some clinical characteristics of the disease may develop. METHODS We discussed the case of a 39-Year old man who presented with persistent abdominal pain of unknown origin after traveling to a high-altitude place. He underwent laparotomy without a definite diagnosis. After that, the patient developed signs of splenic infarction and pulmonary thromboembolism that were confirmed by computed tomography. RESULTS A sickling test was positive, and a hemoglobin electrophoresis revealed an abnormal fraction at the HbS level. In this context a diagnosis of SCT was made. Additional, tests revealed a strongly positive lupus anticoagulant. CONCLUSION SCT presentatio...
