RESUMO

OBJECTIVE: Cellular and humoral immunity plays a role in the pathogenesis of vitiligo. T lymphocytes and natural killer cells involved in cellular immunity carry out their cytotoxic activities through perforin/granzyme-dependent granule exocytosis, in which granulysin and cathepsin-L are also involved. The aim of this study was to investigate the possible role of serum granulysin and cathepsin-L in the etiopathogenesis of vitiligo and their association with disease activity and severity. METHODS: This randomized, prospective case-control study was conducted with 46 vitiligo patients admitted to the hospital for vitiligo between January and November 2021 and 46 healthy volunteers of similar age and gender. Serum levels of granulysin and cathepsin-L were measured by the enzyme-linked immunosorbent assay method. RESULTS: The mean serum levels of granulysin and cathepsin-L were statistically significantly higher in vitiligo patients compared with the control group (p=0.048 and p=0.024, respectively). There was no statistically significant correlation between serum granulysin and serum cathepsin-L levels and disease severity in the patient group (r=0.30, p=0.062 and r=0.268, p=0.071, respectively). Disease activity also showed no significant association with serum granulysin and cathepsin-L levels (p=0.986 and p=0.962, respectively). CONCLUSION: Although granulysin and cathepsin-L are molecules involved in the pathogenesis of vitiligo, the use of these molecules may not be helpful in assessing disease activity and severity. It may be helpful to conduct comprehensive and prospective studies to find new molecules to fill the gap in this area.

RESUMO

Coronavirus disease 2019 (COVID-19) remains a health problem worldwide. The present study aimed to investigate the effect of blood pressure (BP) on the circadian pattern and prevalence of new-onset non-dipper hypertension in the post-COVID period in patients with known hypertension. This prospective single-center study included 722 patients hospitalized for COVID-19 infection. Ambulatory BP (ABP) data were collected during their initial hospitalization. The ABP data were reassessed 1 month after the patients were discharged. The results were compared with a healthy control group with known hypertension but without COVID-19 infection. After exclusion criteria were applied, the study included 187 patients with COVID-19 and 136 healthy hypertensive controls. Post-COVID ABP showed that patients with COVID-19 had significantly higher mean 24-h systolic and diastolic BP, mean nighttime systolic and diastolic BP, and mean daytime diastolic BP than the control group. In addition, new-onset non-dipper hypertension was significantly higher in patients with COVID-19. This study demonstrated for the first time that the circadian pattern is disturbed and a non-dipper pattern develops in individuals with known hypertension during the post-COVID period.

RESUMO

BACKGROUND: R wave peak time (RWPT) is also known as intrinsicoid deflection time or ventricular activation time. It shows the conduction time from the endocardium in the ventricle to the epicardium. It provides diagnostic and prognostic information for many cardiovascular diseases, such as RWPT prolongation, left ventricular hypertrophy, volume overload, conduction system abnormalities, and myocardial ischemia. Objectives The aim of this study is to investigate the relationship between COVID-19 mortality and RWPT in superficial ECG. METHODS: This study retrospectively examined 640 patients diagnosed with COVID-19 and treated in an intensive care unit at a single center between January 2021 and June 2022. All patients included in the study had clinical and radiological characteristics and signs of COVID-19 pneumonia. RESULTS: 640 patients included in the study were divided into 2 groups: surviving and deceased. There were 510 patients in the surviving group and 130 patients in the deceased group. The deceased group was found to be significantly older. The number of patients with COPD was higher in the deceased group. Troponin, lactate dehydrogenase (LDH), C-reactive protein (CRP), D-dimer and T-peak to T-end interval(Tpe) and RWPT were found to be significantly increased in the deceased group. In binary logistic regression analysis; age, COPD, LDH, CRP, troponin, D-dimer, Tpe interval, RWPT were determined as independent risk factors for mortality. CONCLUSIONS: Prolonged RWPT is useful in risk stratification for COVID-19 pneumonia mortality.

RESUMO

BACKGROUND: In addition to coronary artery disease, non-high-density lipoprotein(non-HDL-C) provides short and long-term predictive information for many chronic inflammatory diseases such as stroke, hemodialysis, post-renal transplant, non-alcoholic hepatosteatosis, and human immunodeficiency virus. OBJECTIVES: This study examined the predictive value of non-HDL-C measured before SARS-CoV-2 for mortality in COVID-19 infection. METHODS: This study retrospectively included 1435 patients diagnosed with COVID-19 and treated in the thoracic diseases ward in a single center between January 2020 and June 2022. All patients included in the study had clinical and radiological features and signs of COVID-19 pneumonia. The COVID-19 diagnosis of all patients was confirmed by a polymerase chain reaction studied from an oropharyngeal swab. Statistical significance was set at p < 0.05. RESULTS: The study patients, including 1435 subjects, were divided into 712 patients in the non-surviving group and 723 in the surviving group. While there was no difference between the groups regarding gender, there was a statistically significant age difference. The non-surviving group was older. Age, lactate dehydrogenase(LDH), C reactive protein(CRP), triglycerides, D-dimer, and non-HDL-C were independent risk factors for mortality in regression analyses. In correlation analysis, age, CRP, and LDH were positively correlated with non-HDL-C. In the ROC analysis, sensitivity for non-HDL-C was 61.6%, and specificity was 89.2%. CONCLUSION: We believe that the non-HDL-C level studied before COVID-19 infection can be used as a prognostic biomarker for the disease.


FUNDAMENTO: Além da doença arterial coronariana, a lipoproteína de não alta densidade (não-HDL-C) fornece informações preditivas de curto e longo prazo para muitas doenças inflamatórias crônicas, como acidente vascular cerebral, hemodiálise, pós-transplante renal, hepatoesteatose não alcoólica e vírus da imunodeficiência humana. OBJETIVOS: Este estudo examinou o valor preditivo do não-HDL-C medido antes do SARS-CoV-2 para mortalidade na infecção por COVID-19. MÉTODOS: Este estudo incluiu retrospectivamente 1.435 pacientes diagnosticados com COVID-19 e tratados na enfermaria de doenças torácicas em um único centro entre janeiro de 2020 e junho de 2022. Todos os pacientes incluídos no estudo apresentavam características clínicas e radiológicas e sinais de pneumonia por COVID-19. O diagnóstico de COVID-19 de todos os pacientes foi confirmado por uma reação em cadeia da polimerase estudada a partir de um swab orofaríngeo. A significância estatística foi estabelecida em p < 0,05. RESULTADOS: Os pacientes do estudo, incluindo 1.435 indivíduos, foram divididos em 712 pacientes no grupo de não sobreviventes e 723 no grupo de sobreviventes. Embora não tenha havido diferença entre os grupos em relação ao sexo, houve uma diferença de idade estatisticamente significativa. O grupo que não sobreviveu era mais velho. Idade, lactato desidrogenase (LDH), proteína C reativa (PCR), triglicerídeos, D-dímero e não-HDL-C foram fatores de risco independentes para mortalidade em análises de regressão. Na análise de correlação, idade, PCR e LDH foram positivamente correlacionados com não-HDL-C. Na análise ROC, a sensibilidade para não-HDL-C foi de 61,6% e a especificidade foi de 89,2%. CONCLUSÃO: Acreditamos que o nível de não HDL-C estudado antes da infecção por COVID-19 pode ser usado como um biomarcador prognóstico para a doença.

RESUMO

BACKGROUND: Acute localized exanthematous pustulosis (ALEP), a localized variant of acute generalized exanthematous pustulosis, is characterized by pin-sized, non-follicular, sterile pustules that typically appear on the face, neck, and chest. OBJECTIVE: The purpose of this report is to describe a case of ALEP in an 11-year-old girl because of cefixime and the etiological factors and clinical presentation of ALEP in pediatric group. METHODS: We described a case of ALEP in an 11-year-old girl because of cefixime; a systematic review of the literature was performed to identify the etiological factors and clinical presentation of ALEP in children. RESULTS: We identified eight pediatric cases with ALEP. The causative agent was an herbal product in six cases, and pustular eruption was located on the face. In two cases, responsible agents were drugs (lamotrigine and amoxicillin-clavulanic acid). The eruptions were localized on the penis and extremities, respectively. CONCLUSION: ALEP is very rare in the pediatric age group, and topical/systemic drugs or herbal products may be involved in the etiology.

RESUMO

Introduction: The increasing frequency of cardiac device use has led to an increase in complication rates. The standard treatment for cardiac device-related infections is removal of the entire pacemaker system and reimplantation from the contralateral side after systemic antibiotherapy. The efficacy of various conservative treatments has been established for many years, but there is conflicting information in the literature regarding long-term efficacy. Aim: Our study investigated the long-term efficacy of conservative treatment in patients with pacemaker pocket site infection. Material and methods: In this retrospective study, according to the exclusion criteria, 132 patients were included. Patients were divided into conservative and standard treatment groups. Conservative treatment was considered to be opening the pacemaker pocket capsule, removing all infected and necrotic tissue, cleaning the capsule, and embedding the battery in the prepectoral region in the subpectoral muscle region. Results: The follow-up time was 36 ±12.96 months in the conservative treatment group and 39.6 ±10.8 months in the standard treatment group. During this period, no re-infection at the pacemaker pocket site was observed in either group. Examination of the swab cultures of the patients' pacemaker wounds revealed negative culture results in 15 patients (15 out of 60) in the conservative treatment group. In the standard treatment group, 60 patients (60 out of 72) were culture-negative. This difference was statistically significant (p = 0.04). Conclusions: After a rigorous evaluation, conservative treatment is considered effective and safe in the long term in patients with device pocket site infection.

RESUMO

Objective: It is increasingly important to identify risk factors for COVID-19-associated mortality to provide access to early treatment. This study aimed to investigate the relationship between COVID-19 severity and laboratory data and demographic characteristics of hospitalized patients and to identify factors predicting mortality in COVID-19. Materials and Methods: The study is a retrospective and single-center study. Data of 1298 COVID-19 patients confirmed by a positive real-time polymerase chain reaction test for COVID-19 and treated at the hospital were retrospectively analyzed. Study patients were divided into three groups based on the clinical severity of disease: the mild-moderate group (n:954) and the severe (n:310) and critical (n:34) groups. Demographic characteristics, underlying diseases, and laboratory findings were compared between groups. Results: Multivariate logistic and ordinal logistic regression analysis revealed that male gender, old age, diabetes mellitus, coronary artery disease, cerebrovascular event, malignancy, chronic obstructive pulmonary disease, chronic renal failure, chronic hepatitis B, and Alzheimer's disease/dementia/Parkinson's disease (among neurological diseases) were independently associated with and significantly increased the development of severe disease and mortality. Conclusion: The COVID-19 pandemic continues to be a significant health problem affecting all of humanity. Determining risk factors for COVID-19 severity and mortality are critical for classifying critical cases at the time of initial diagnosis, establishing appropriately specific treatment protocols, and ensuring access to early treatment.
