Risk factors for relapse after discontinuation of tenofovir or entecavir in hepatitis B e antigen-negative patients.

Background and Aim: This study aimed to define the relapse frequency and risk determinants in chronic hepatitis B (CHB) patients who discontinued nucleoside analog (NA) treatment, were HBeAg-negative, and had achieved both a virological and biochemical response. Materials and Methods: This retrospective cohort study reviewed patients with HBeAg-negative CHB who received antiviral therapy for at least 65 months between January 1, 2013, and December 31, 2020. These patients discontinued treatment after demonstrating a biochemical and virological response and were evaluated at 6, 12, and 24 months post-treatment discontinuation. Results: Sixty-seven patients with CHB who received NA therapy for at least 65 months, discontinued treatment, and had undetectable HBV DNA and normal ALT values were evaluated. After cessation of NA therapy, a relapse was observed in 38 patients (56.7%). The relapse rate was 71.0% in patients treated with tenofovir disoproxil fumarate (TDF) as the last NA type and 37.9% in patients treated with entecavir (ETV) (p=0.017). The cutoff value for the best estimate of age for predicting relapse was 42 years. The relapse rate was 69.2% in patients aged ≥42 years and 39.2% in patients aged <42 years (p=0.007). The relapse rate was 51.3% in patients with a pre-treatment fibrosis score of 2, 56.0% in those with a fibrosis score of 3, and 100% in those with a fibrosis score of 4 (p=0.089). Conclusion: Among HBeAg-negative CHB patients who achieved a virological and biochemical response to long-term antiviral therapy, those aged 42 years and older, those with high fibrosis scores before treatment, and those who used TDF before treatment cessation should be closely monitored for relapse, especially in the first 12 months after stopping NA treatment.

Evaluation of chronic hepatitis B patients who voluntarily discontinued oral antiviral therapy: is there an answer to the controversial topic?

OBJECTIVE: The uncertain treatment duration for nucleos(t)ide analogues (NA) used in the treatment of chronic hepatitis B (CHB) is an important problem for both patients and physicians. The aim of this study was to evaluate the determinants of virologic relapse (VR) and the optimum time of treatment discontinuation in the follow-up of CHB patients who voluntarily discontinued treatment after virological suppression was achieved under NA use. METHODS: Data from 138 patients from 11 centers were included in this registry-based study. Factors associated with VR were investigated using multivariate Cox regression analysis. RESULTS: Ninety-nine (71.7%) of the patients were HBeAg (Hepatitis B e antigen) negative. During the 24-month follow-up period after treatment discontinuation, VR occurred in 58.7% (n = 81) of all patients and 57.6% (n = 57) of HBeAg-negative patients. The duration of NA treatment was significantly shorter (cutoff 60 months) in HBeAg-negative patients who later developed VR. In addition, the duration of virologic remission achieved under NA treatment was significantly shorter (cutoff 52 months) in those who later developed VR. In the Cox multivariate regression model of HBeAg-negative patients, having less than 60 months of NA treatment (HR = 2.568; CI:1.280-5.148; P  = 0.008) and the levels of alanine aminotransferase being equal to or higher than twice the upper level of normal at the beginning of treatment (HR = 3.753; CI:1.551-9.081; P  = 0.003) were found to be statistically significant and independently associated with VR. CONCLUSION: The findings of this study may provide clinical guidance in terms of determining the most appropriate discontinuation time for NA.

Bacterial colonization due to increased nurse workload in an intensive care unit / Colonização bacteriana por causa do aumento da carga de trabalho da equipe de enfermagem em unidade de terapia intensiva / Colonización bacteriana debido al aumento de la carga de trabajo del equipo de enfermería en una unidad de cuidados intensivos

INTRODUCTION: The rates of multiresistant bacteria colonization or infection (MRB+) development in intensive care units are very high. The aim of this study was to determine the possible association between the risk of development of nosocomial infections and increased daily nurse workload due to understaffing in intensive care unit. METHODS: We included 168 patients. Intensity of workload and applied procedures to patients were scored with the Project de Recherché en Nursing and the Omega scores, respectively. The criteria used for infections were those defined by the Centers for Disease Control. RESULTS: Of the 168 patients, 91 (54.2%) were female and 77 (45.8%) were male patients. The mean age of female and male was 64.9 ± 6.2 years and 63.1 ± 11.9 years, respectively. The mean duration of hospitalization in intensive care unit was 18.4 ± 6.1 days. Multiresistant bacteria were isolated from cultures of 39 (23.2%) patients. The development of MRB+ infection was correlated with length of stay, Omega 1, Omega 2, Omega 3, Total Omega, daily PRN, and Total PRN (p < 0.05). There was no correlation between development of MRB+ infection with gender, age and APACHE-II scores (p > 0.05). CONCLUSION: The risk of nosocomial infection development in an intensive care unit is directly correlated with increased nurse workload, applied intervention, and length of stay. Understaffing in the intensive care unit is an important health problem that especially affects care-needing patients. Nosocomial infection development has laid a heavy burden on the economy of many countries. To control nosocomial infection development in the intensive care unit, nurse workload, staffing level, and working conditions must be arranged. .

INTRODUÇÃO: As taxas de desenvolvimento de infecção ou colonização por bactérias multirresistentes (BMR+) em unidades de terapia intensiva são muito elevadas. O objetivo deste estudo foi determinar a possível associação entre o risco de desenvolvimento de infecções hospitalares e o aumento da carga de trabalho diária da equipe de enfermagem devido à insuficiência de pessoal em unidade de terapia intensiva. MÉTODOS: Cento e sessenta e oito pacientes foram incluídos. O volume da carga de trabalho e os procedimentos realizados em pacientes foram avaliados com o uso de instrumentos de medidas como o Projeto de Pesquisa em Enfermagem (Project de Recherché en Nursing) e o Omega, respectivamente. Os critérios usados para definir infecções foram os definidos pelos Centros de Controle de Doenças. RESULTADOS: Dos 168 pacientes, 91 (54,2%) eram do sexo feminino e 77 (45,8%) do sexo masculino. As médias das idades de mulheres e homens foram 64,9 ± 6,2 e 63,1 ± 11,9 anos, respectivamente. A média do tempo de internação em unidade de terapia intensiva foi de 18,4 ± 6,1 dias. As bactérias multirresistentes foram isoladas a partir de culturas de 39 (23,2%) pacientes. O desenvolvimento de infecção por BMR+ foi correlacionado com tempo de internação, Omega 1, Omega 2, Omega 3, Omega total, PPE diário e PPE total (p < 0,05). Não houve correlação entre desenvolvimento de infecção por BMR+ e gênero, idade e escores no APACHE-II (p > 0,05). CONCLUSÃO: O risco de desenvolvimento de infecção hospitalar em unidade de terapia intensiva está diretamente relacionado com o aumento da carga de trabalho de enfermagem, as intervenções praticadas e o tempo de internação. A falta de pessoal em unidade de terapia intensiva é um problema de saúde importante que afeta principalmente os pacientes que requerem cuidados.

Brucellar epididymo-orchitis in southeastern part of Turkey: an 8 year experience

OBJECTIVE: the different clinical and laboratory features and response to treatment of patients with acute brucellar epididymo-orchitis (BEO) reporting to the reference hospital in Southeastern Anatolia of Turkey. MATERIAL AND METHODS: in this study, 27 male patients with brucellosis, who presented with epididymitis or epididymo-orchitis (EO) at the university hospital in Diyarbakir from 1998 to 2006, were included. They were compared with the other male patients. Positive blood culture or high agglutination titers of > 1/160 and positive clinical manifestations of brucellosis were the main criteria for diagnosing brucellosis. RESULTS: fourteen patients had unilateral EO. Leukocytosis was present in 10 patients; all of them had initial agglutination titers of > 1/160 and 10 patients had a positive blood culture. All patients received combined therapy with streptomycin for the first 21 days (or oral rifampicin for 6-8 weeks) with doxycycline or tetracycline for 6-8 weeks. All showed improvement, fever subsided in 3-7 days, and the scrotal enlargement and tenderness regressed. Only one patient had a relapse within one year. CONCLUSION: in brucellosis-endemic areas, clinicians encountering EO should consider the likelihood of brucellosis. In this study, young age was the most common risk factor, and leukocytosis and high CRP level were the most common laboratory findings. Most cases were unilateral. All patients responded to medical management very well. Conservative management with combination antibiotic therapy was adequate for managing BEO. Conclusively, brucellosis must be considered as a cause of orchitis, especially in endemic regions like Turkey.

The evaluation of bacteriology in perianal abscesses of 81 adult patients

OBJECTIVE: Treatment of perianal abscesses requires prompt surgical drainage and antimicrobial therapy. However, we should encourage the selective use of antimicrobial agents on a case-by-case basis, especially because there is no evidence that uncomplicated perianal abscesses can be safely treated only with drainage. For this reason, it is important to identify the causative organisms; therefore, we accessed the microbiological analysis of these patients. PATIENTS AND METHODS: In this study, 81 consecutive adult patients with perianal abscesses, who presented at a university hospital in Diyarbakir from January 2004 to December 2006, were included. Clinical and laboratory data, and results of microbiological analysis were recorded. RESULTS: All specimens, except seven, yielded bacterial growth. Escherichia coli, Bacteriodes spp., coagulase-negative Staphylococci, and Staphylococcus aureus were the most common isolated organisms. CONCLUSION: In contrast to other investigators, this study demonstrated that aerobic organisms are the predominant isolates in these infections.
