ABSTRACT

Background Direct-acting antivirals (DAA) allowed a radical change in the treatment of hepatitis C virus (HCV), achieving the elimination of the virus or sustained viral response (SVR) in > 95% of patients, with good tolerance and few adverse effects. Aim To characterize the treated population and evaluate the efficacy of DAA treatment in the Chilean public health system. Material and Methods: Retrospective analysis of data sheets of pa- tients with chronic HCV infection collected by the Ministry of Health of Chile between 2016 and May 2019. Results Two hundred and fifty-five patients with a mean age of 59 years (51% males) were collected. Genotype 1b was predominant, 72% patients had a diagnosis of cirrhosis at the beginning of treatment. Sofosbuvir-Velpatasvir was predominantly used in 56%. SVR was achieved in 92% of cases, only 4% persisted with detectable load at 24 weeks. A significant decrease in alanine aminotransferase values (88 and 31 U/L respectively, p < 0.01) and a significant increase in plasma albumin (3.7 and 3.9 mg/dl respectively, p = 0.02) were observed. The comparative analysis of MELD-Na before and after treatment did not show a signifi- cant variation (10.8 and 10.4 respectively, p = 0.34). Conclusions These patients treated with DAAs presented SVR rates comparable with national and international data.

ABSTRACT

Background: In Chile, organ allocation for liver transplantation (LT) in adults is prioritized according to the MELD-Na score. Exceptions such as Hepatocellular Carcinoma (HCC) and other non-HCC exceptions receive a score called Operational MELD score. Aim: To evaluate the effectiveness of the MELD-Na score and the operational MELD score as a prioritization system for LT in Chile. Material and Methods: Retrospective analysis of the waiting list (WL) of adult candidates (≥ 15 years) for elective LT in Chile from 2011 to 2017. The probability of leaving the WL, defined by death or contraindication for LT was compared in three groups: 1) Cirrhotic patients prioritized according to their real MELD-Na score (CPM), 2) HCC and 3) other non-HCC exceptions. Results: We analyzed 730 candidates for LT, with a median age of 57 years, 431 (56%) were men. In the study period, 352 LT were performed (48%). The annual exit rate was significantly higher in the CPM group (45.5%) compared to HCC (33.1%) and non-HCC (29.3%), (p < 0.001). Post LT survival was 86% at 1 year and 85% at 5 years, without significant differences between groups. In the CPM group, post-transplant survival was significantly lower (p < 0.05) in patients with MELD-Na ≥ 30 at transplant (81% per year) compared to patients with patients with MELD-Na < 30 (91% per year). Conclusions: MELD-Na score can discriminate very well patients who have a higher risk of death in the short and medium term. However, the assignment of operational scores for situations of exception produces inequities in the allocation of organs for LT and must therefore be carefully adjusted.

ABSTRACT

Liver involvement occurs in 0.2 to 3% of patients with syphilis. We report three patients with liver involvement in syphilis. A 52-year-old male presenting with erythema and malaise. Laboratory showed a gamma glutamyl transpeptidase (GGT) of 853 u/l, alkaline phosphatases of 1,010 U/L and VDRL was positive. Treatment with penicillin resolved the skin problem and normalized liver enzymes. A HIV positive 30-year-old male in peritoneal dialysis presenting with itching, malaise and markedly elevated GGT and alkaline phosphatases. VDRL was positive. He was treated with penicillin with remission of symptoms and enzyme normalization. A 43-year-old male presenting with erythema, malaise, arthralgias and elevated GGT and alkaline phosphatases. VDRL was positive and treatment with penicillin reverted symptoms and laboratory abnormalities.

ABSTRACT

Background: The association of stress and acute coronary events has been extensively explored. An increased output of catecholamines leading to high blood pressure and alteration of hemostasis may be responsible for this effect. A severe earthquake and tsunami is a major stress. Methods and Results. 280,592 electrocardiograms (ECG) obtained via a telemedicine system in the years 2009 and 2010 were analyzed. The frequency of subepicardial lesions recorded during the weekend in which the earthquake took place (27/2/2010 - 28/2/2010) was compared to that observed in all other weekends throughout the period. 7 subjects had a blood pressure Holter monitoring on that weekend. A subepicardial lesion was diagnosed in 0.64% of ECGs recorded throughout the period, increasing significantly in the earthquake's weekend (p<0.05). The age distribution of subepicardial lesions was similar in all weekends. However, the higher proportion of males with sub epicardial lesions throughout the study period changed to a higher proportion of females in the earthquake's weekend. Significant increases in blood pressure and heart rate were observed in coincidence with the earthquake in patients undergoing blood pressure monitoring. Conclusion: a statistically significant increase in subepicardial lesions demonstrated by telemedicine ECG recordings was associated to the stressful situation of the 2010 earthquake in Chile.


La asociación de estrés y eventos coronarios agudos ha sido extensamente estudiada. En relación a un evento estresante existiría un aumento en la liberación de ca-tecolaminas que incide en un incremento en la presión arterial y alteraciones de hemostasia, como sería el caso de un terremoto. En el presente trabajo se describe la relación contemporánea observada entre el terremoto del 27 de febrero del 2010 y el diagnóstico de lesión subepicárdica, en electrocardiogramas recibidos en ITMS, Telemedicina de Chile. Se analizaron 280.592 electrocardiogramas (ECGs) provenientes de todo el territorio nacional, que corresponden a un periodo de 12 meses de los años 2009 y 2010. Se realizó una comparación estadística entre el porcentaje de lesiones subepicárdicas registradas en el fin de semana del terremoto (27/02/2010 y 28/02/2010) versus los fines de semana de los meses estudiados. Se obtuvieron los datos correspondientes a siete pacientes que se encontraban con monitoreo ambulatorio de presión arterial (MAPA) el día 27/02. El diagnóstico de lesión subepicárdica se hizo en 1.795 trazados, correspondientes a un 0.64% del total de ECGs recibidos. Hubo un aumento estadísticamente significativo de las lesiones subepicárdicas (p<0,05) en el fin de semana del terremoto, la distribución por edad se mantuvo similar al resto de los períodos analizados. Sin embargo se invirtió la distribución por género durante dicho fin de semana siendo mayor en mujeres que en hombres, como es en el resto de los períodos analizados. En los registros MAPA se documentó un aumento de la presión arterial y frecuencia cardíaca en relación al evento estresante. Se confirmó entonces un aumento estadísticamente significativo del diagnóstico electrocardiográfico de lesiones subepicárdicas en relación al estrés producido por el terremoto del 27 de febrero de 2010.
