Abstract

The lesser grain borer, Rhyzopertha dominica is one of the serious cosmopolitan stored grain pests worldwide. High phosphine resistant R. dominica has been reported in several countries. The evolution of strong phosphine resistance is a major challenge for continuous application of the fumigant. Rapid detection of phosphine resistance level is a prime key to implement an appropriate strategy for control the stored-product pests. Dihydrolipoamide dehydrogenase (DLD) is a key metabolic enzyme mediating the phosphine resistance in population of R. dominica, Tribolium castaneum and Caenorhabditis elegans. Analysis of the DLD sequences deposited in GenBank revealed that the P45/49S mutation was the most common one in many PH3-resistant stored-product pest insects. This information now enables direct detection of resistance using molecular diagnosis in field populations. We herein propose a method for rapid detection of phosphine resistance in R. dominica according to P49S point mutation of the DLD gene. Our data provides evidence that the ARMS-PCR method can be used for early warning of phosphine resistance in R. dominica in field conditions.

Abstract

Objective: To analyze the pathological types, clinical characteristics and outcomes of human immunodeficiency virus (HIV)-infected patients with chronic kidney diseases (CKD). Methods: Thirty-two cases of HIV infection combined with CKD who underwent ultrasound guided renal biopsy in Shanghai Public Health Clinical Center from June 2016 to April 2021 were enrolled. Pathological types, clinical conditions and outcomes were all analyzed. Results: Among the 32 patients, there were 28 male and 4 female, with an average age of (43.5±12.3) years. The CD4+T lymphocyte count was (425.9±240.4) cells/μL. Twenty-six patients (81.3%) had been treated with antiretroviral therapy before renal puncture biopsy, and the median treatment time was 24 (1, 72) months. Among the pathological types, membranous nephropathy (8 cases, 25.0%) and IgA nephropathy (6 cases, 18.8%) accounted for the most types, followed by diabetic nephropathy (5 cases, 15.6%). No classical HIV-related nephropathy was found. During the follow-up period of 3 months to 5 years, the remission rate of renal disease reached 84.4% (13 complete remissions, 14 partial remissions), and the unresponsive rate was 9.4% (3 cases, including 1 case of lupus like immune complex mediated proliferative glomerulonephritis, 1 case of diabetes nephropathy, and 1 case of hypertensive nephropathy). The mortality rate was 6.3%(2 cases, all minor lesions). Conclusions: This study shows that the pathological types of HIV infected patients with CKD are various. Membranous nephropathy is predominant pathological type, and followed by IgA nephropathy and diabetes nephropathy, but classical HIV related nephropathy is not common. According to the pathological results of renal biopsy, renal disease related treatment based on antiretroviral therapy can alleviate renal disease or delay the progression of renal disease, but the prognosis of patients with minimal change nephropathy may be poor.
