The prognostic value of platelet-to-lymphocyte ratio on the long-term renal survival in patients with IgA nephropathy

Purpose

Platelet-to-lymphocyte ratio (PLR) was established showing the poor prognosis in several diseases, such as malignancies and cardiovascular diseases. But limited study has been conducted about the prognostic value of PLR on the long-term renal survival of patients with Immunoglobulin A nephropathy (IgAN).

Methods

We performed an observational cohort study enrolling patients with biopsy-proven IgAN recorded from November 2011 to March 2016. The definition of composite endpoint was eGFR decrease by 50%, eGFR?<?15 mL/min/1.73 m², initiation of dialysis, or renal transplantation. Patients were categorized by the magnitude of PLR tertiles into three groups. The Kaplan–Meier curves and multivariate Cox models were performed to determine the association of PLR with the renal survival of IgAN patients.

Results

330 patients with a median age of 34.0 years were followed for a median of 47.4 months, and 27 patients (8.2%) had reached the composite endpoints. There were no differences among the three groups (PLR?<?106, 106?≤?PLR?≤?137, and PLR?>?137) in demographic characteristics, mean arterial pressure (MAP), proteinuria, and estimated glomerular filtration rate (eGFR) at baseline. The Kaplan–Meier curves showed that the PLR?>?137 group was significantly more likely to poor renal outcomes than the other two groups. Using univariate and multivariate cox regression analyses, we found that PLR?>?137 was an independent prognostic factor for poor renal survival in patients with IgAN. Subgroup analysis revealed that the PLR remained the prognostic value for female patients or patients with eGFR less than 60 mL/min/1.73 m².

Conclusions

Our results underscored that baseline PLR was an independent prognostic factor for poor renal survival in patients with IgAN, especially for female patients or those patients with baseline eGFR less than 60 mL/min/1.73 m².

     

Nonalcoholic fatty liver disease and risk of prostatic diseases: Roles of insulin resistance

Nonalcoholic fatty liver disease (NAFLD), the liver component of metabolic syndrome, is considered to be associated with high risk of prostatic diseases but a systematic review has not been conducted. Under a comprehensive review of the eligible clinical studies, a potential positive association between NAFLD and benign prostatic hyperplasia/prostate cancer (BPH/PCa) has been postulated. Insulin resistance and metabolic aberrations are considered to be the potential mechanism for such association. However, the relationship between NAFLD and other prostatic diseases, that is, prostatic inflammation and lower urinary tract symptoms, seems vague due to limited relevant studies in the literatures. The present review highlights that clinicians should be conscious of the detrimental effect of NAFLD on the development of BPH and PCa.     

Complete urethral injury in the penile fracture: a case report and literature review

Penile fracture is described as a traumatic rupture of the tunica albuginea caused by blunt injury to the erect penis. It usually occurs as a single rupture of the tunica albuginea in one of two corpora cavernosa; a rupture with urethral injury is an extremely rare condition. Although its diagnosis is usually clinical, ultrasound plays an important role in confirming diagnosis and identifying the site of the injury. Here, we presented a case of penile fracture with complete urethral injury. A 43-year-old male was admitted to the hospital because of trauma to the genital and dysuria following sexual intercourse. After admission, the patient was diagnosed with double penile fracture and complete urethral injury after the physical and B-ultrasound examinations. Emergency surgery to remove the hematoma and repair the urethra was performed. The patient recovered smoothly and was discharged on the third day after operation. After two months’ follow-up, the patient urinated smoothly and achieved an adequate erection without other complications. In this case, consistent with previous studies, emergency surgery for penile fracture is necessary and can preserve the urethral function and sexual function. In addition, there are two lesions in tunica albuginea in this case, so careful search for the penile shaft during the surgery is important to avoid the missed injuries. This report provides evidence of an uncommon and underreported clinical case.     

Variations of Concentration Characteristics of Rainfall Runoff Pollutants in Typical Urban Living Areas

Based on a typical residential area, this paper studies the characteristics of pollutant concentration changes in two rainfall runoffs and the first flush effect of rainfall. In rainfall runoff, the concentrations of seven pollutants (COD_Mn, TN, DTN, NH₃-N, TP, DTP, and PO₄³⁻) increased during the initial rainfall period and decreased in the later period. Rainfall causes the erosion of pollutants on the underlying surface so that water pollution begins when rainfall runoff occurs, and the pollution level drops over time. The seven pollutants all experience this first flush effect, of which, rainfall has the strongest scouring effect on NH₃-N produced by domestic sewage. The significant excess of pollutants in rainfall runoff should be considered by management departments. In addition, the existence of the first flush effect makes it possible in theory to partially intercept rainfall runoff to control water pollution, thereby reducing the cost of pollution control.
