ABSTRACT

Herpes zoster (HZ) represents a serious health problem in the general population due to its abundance and complications. Stroke and acute myocardial infarction are well-documented short-term complications of HZ, primarily due to vasculopathy in the cerebral and coronary arteries. However, no major study to date has specifically demonstrated that HZ is a long-term risk factor for all Major Adverse Cardiac and Cerebrovascular Events (MACCE). A retrospective cohort study was conducted analyzing the association between HZ and MACCE. We compared HZ patients diagnosed between 2001 and 2018 and a matched control group. The model was stratified according to matched pairs and adjusted for age, socioeconomic status, history of dyslipidemia, and prior myocardial infarction (MI). Association between HZ exposure and stroke was assessed through a multivariable Cox regression analysis. The study included 41,930 patients, with 20,965 patients in each group. The risk of MACCE was 19% higher among HZ patients in the first year of follow up (P < 0.001). Antiviral treatment did not positively affect long-term survival among HZ patients (P < 0.001). These results suggest that HZ is a marker of long-term vascular risk. Additional studies will be needed to further evaluate this risk, the impact of HZ vaccination on such risk, and potential mitigation strategies.

ABSTRACT

PURPOSE: To evaluate whether the neutrophil-to-lymphocyte ratio (NLR) can predict the need for ureteral catheterization in patients with renal colic. MATERIALS AND METHODS: We retrospectively studied 15,887 patients with renal colic between 2005 and 2019. Patients with prior antibiotics treatment (156), with hematological diseases (15), with negative computerized tomography scan (CTS) for stone disease (473) or with no available laboratory findings (1750) were excluded. A ureteral double J stent (DJS) was inserted in case of ongoing pain, fever, sepsis, single kidney and elevated blood creatinine levels concomitant with hydronephrosis. A cut-off value of 2.1 NLR was determined to stratify and to compare patients using multivariable logistic regression models. A locally weighted scatterplot smoothing (LOWESS) plot was also applied to show the relationship between NLR and predicted probability for DJS insertion. RESULTS: Thirteen-thousand and 493 patients with a mean age of 42.7 years (30% females and 70% males) were included in the study. Five-hundred and 57 patients (4.1%) underwent early DJS insertion: 5.3% vs. 1.5% of patients with high vs. low NLR, respectively, (p<0.001). High NLR was significantly associated with longer hospitalization time, admission to the intensive care unit and overall mortality within a month from admission (p<0.05). LOWESS plot showed that NLR value >2.1 escalates progressively the probability for DJS insertion. CONCLUSIONS: A high NLR is associated with the need for early internal DJS insertion due to urolithiasis. The NLR is easily calculated from simple blood tests and based on our results can be used for clinical decision making in patients with renal colic needing renal decompression.
