Abstract
INTRODUCTION The current systematic review aimed to collect and analyze the comprehensive evidence regarding Polymerase Spiral Reaction (PSR) and to estimate its diagnostic performance and usefulness as a point-of-care (PoC) assay. METHODS Literature was retrieved systematically from 2015 to 2023 from PubMed and Scopus. Studies were screened and selected against pre-determined inclusion and exclusion criteria. Quality assessment and risk of bias were critiqued using QUADAS-2. A systematic, qualitative narrative synthesis was employed to synthesize the data. RESULTS 11 studies were selected for the systematic review, testing diseases in humans utilizing PSR. Only 2 studies clinically validated the test with a sample size > 150. 5 studies were of poor quality; 3 studies were of moderate quality and 3 studies were deemed to be of high quality. 3 studies quantified the diagnostic throughput and reported clinical sensitivity and specificity of PSR approaching to be > 92% and ~ 100%, respectively. CONCLUSION Polymerase spiral reaction promises to be an optimistic isothermal assay; however, a huge research gap can be attributed to the lack of statistical and clinical evidence to validate the assay. Adequate research, focused on optimization, coupled with statistical and clinical validation, can help in estimating its true diagnostic potential and applicability.

Sakhabutdinova AR, Chemeris AV, Garafutdinov RR. Detection of Specific RNA Targets by Multimerization. BIOCHEMISTRY. BIOKHIMIIA 2023; 88:679-686. [PMID: 37331713 DOI: 10.1134/s0006297923050103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 02/26/2023] [Accepted: 03/09/2023] [Indexed: 06/20/2023]
Abstract
Detection of specific RNA targets via amplification-mediated techniques is widely used in fundamental studies and medicine due to essential role of RNA in transfer of genetic information and development of diseases. Here, we report on an approach for detection of RNA targets based on the particular type of isothermal amplification, namely, reaction of nucleic acid multimerization. The proposed technique requires only a single DNA polymerase possessing reverse transcriptase, DNA-dependent DNA polymerase, and strand-displacement activities. Reaction conditions that lead to efficient detection of the target RNAs through multimerization mechanism were determined. The approach was verified by using genetic material of the SARS-CoV-2 coronavirus as a model viral RNA. Reaction of multimerization allowed to differentiate the SARS-CoV-2 RNA-positive samples from the SARS-CoV-2 negative samples with high reliability. The proposed technique allows detection of RNA even in the samples, which were subjected to multiple freezing-thawing cycles.

Abstract
As nucleic acid testing is playing a vital role in increasingly many research fields, the need for rapid on-site testing methods is also increasing. The test procedure often consists of three steps: Sample preparation, amplification, and detection. This review covers recent advances in on-chip methods for each of these three steps and explains the principles underlying related methods. The sample preparation process is further divided into cell lysis and nucleic acid purification, and methods for the integration of these two steps on a single chip are discussed. Under amplification, on-chip studies based on PCR and isothermal amplification are covered. Three isothermal amplification methods reported to have good resistance to PCR inhibitors are selected for discussion due to their potential for use in direct amplification. Chip designs and novel strategies employed to achieve rapid extraction/amplification with satisfactory efficiency are discussed. Four detection methods providing rapid responses (fluorescent, optical, and electrochemical detection methods, plus lateral flow assay) are evaluated for their potential in rapid on-site detection. In the final section, we discuss strategies to improve the speed of the entire procedure and to integrate all three steps onto a single chip; we also comment on recent advances, and on obstacles to reducing the cost of chip manufacture and achieving mass production. We conclude that future trends will focus on effective nucleic acid extraction via combined methods and direct amplification via isothermal methods.

Evaluation of reverse transcriptase-polymerase spiral reaction assay for rapid and sensitive detection of severe acute respiratory syndrome coronavirus 2. Clin Chim Acta 2023; 539:144-150. [PMID: 36528050 PMCID: PMC9750508 DOI: 10.1016/j.cca.2022.12.009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND AND AIM Existing real-time reverse transcriptase PCR (RT-qPCR) has certain limitations for the point-of-care detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) since it requires sophisticated instruments, reagents and skilled laboratory personnel. In this study, we evaluated an assay termed the reverse transcriptase-polymerase spiral reaction (RT-PSR) for rapid and visual detection of SARS-CoV-2. METHODS The RT-PSR assay was optimized using RdRp gene and evaluated for the detection of SARS-CoV-2. The time of 60min and a temperature of 63°C was optimized for targeting the RNA-dependent RNA polymerase gene of SARS-CoV-2. The sensitivity of the assay was evaluated by diluting the in-vitro transcribed RNA, which amplifies as low as ten copies. RESULTS The specific primers designed for this assay showed 100% specificity and did not react when tested with other lung infection-causing viruses and bacteria. The optimized assay was validated with 190 clinical samples in two phases, using automated RTPCR based TrueNat test, and the results were comparable. CONCLUSIONS The RT-PSR assay can be considered for rapid and sensitive detection of SARS-CoV-2, particularly in resource-limited settings. To our knowledge, there is as yet no RT-PSR-based kit developed for SARS-CoV-2.

Abstract
INTRODUCTION Cervical cancer is the most frequent malignancy among women caused by an unresolved long-term infection with distinct human papillomavirus (HPV) genotypes. It is the fourth most common form of cancer among women worldwide. The two oncogenic genotypes, HPV 16 and 18, are responsible for >70% of all cervical cancers worldwide. Cervical cancer is one of the most successfully preventable and treatable forms of cancer if detected early. AREAS COVERED In this review article, we have summarizedsummarised the different approaches used in clinical diagnosis and research laboratories to detect HPV-related changes associated with cervical cancer for a better understanding of the advantages and limitations of these tests. EXPERT OPINION Despite the well-known screening strategies for cervical cancer, developing nations lack effective implementation due to various factors. With the current rate of cervical cancer cases, precise and timely identification of HPV can significantly impact the prevention and efficient management of cervical cancer. Cervical cancer is the most common gynecological cancer in developing countries. The primary screening test with cytology and molecular testing of HPV is important for preventing cervical cancer. To address these issues, several point-of-care assays have been developed to facilitate rapid screening of HPV with the least turnaround time.

[PMID: 36556302 PMCID: PMC9784247 DOI: 10.3390/jpm12122082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 11/17/2022] [Accepted: 12/09/2022] [Indexed: 12/23/2022] Open
Abstract
The rapid and simple detection of Helicobacter pylori (H. pylori) is essential for its clinical eradication. Although various methods for detecting H. pylori have been well established, such as endoscopy in combination with histology or culture, rapid urease test (RUT) and molecular tests using clinical specimens, it is of great importance to develop an ultrasensitive and accurate nucleic acid detection platform and apply it to identify H. pylori. To meet these demands, a novel method based on PCR and CRISPR-Cas13a, called PCR-Cas13a, was developed and validated using the DNA of 84 clinical strains and 71 clinical specimens. PCR primers for the pre-amplification of conservative sequence and CRISPR RNA (crRNA) for the detection of specific sequence were designed according to the principle. The designed primers and crRNA were specific to H. pylori, and the assay showed a high degree of specificity compared with other common pathogens. Our detection system can screen H. pylori with a limit of 2.2 copies/μL within 30 mins after PCR amplification. Using a coincidence analysis with traditional methods, our method exhibited 100% accuracy for the detection of H. pylori. Furthermore, its diagnostic performance was compared, in parallel with a q-PCR. The PCR-Cas13a demonstrates 98% sensitivity and 100% specificity. Moreover, our approach had a lower limit of detection (LOD) than q-PCR. Herein, we present a diagnostic system for the highly sensitive screening of H. pylori and distinguish it from other pathogens. All the results demonstrated that this PCR-based CRISPR assay has wide application prospects for the detection of H. pylori and other slow-growth pathogens.

Abstract
COVID-19 pandemic highlighted the demand for the fast and reliable detection of viral RNA. Although various methods for RNA amplification and detection have been proposed, some limitations, including those caused by reverse transcription (RT), need to be overcome. Here, we report on the direct detection of specific RNA by conventional polymerase chain reaction (PCR) requiring no prior RT step. It was found that Hemo KlenTaq (HKTaq), which is posed as DNA-dependent DNA polymerase, possesses reverse transcriptase activity and provides reproducible amplification of RNA targets with an efficiency comparable to common RT-PCR. Using nasopharyngeal swab extracts from COVID-19-positive patients, the high reliability of SARS-CoV-2 detection based on HKTaq was demonstrated. The most accurate detection of specific targets are provided by nearby primers, which allow to determine RNA in solutions affected to multiple freeze-thaw cycles. HKTaq can be used for elaboration of simplified amplification techniques intended for the analysis of any specific RNA and requiring only one DNA polymerase.

Abstract
A colorimetric sensor array designed on a paper substrate with a microfluidic structure has been developed. This array is capable of detecting COVID-19 disease by tracking metabolites of urine samples. In order to determine minor metabolic changes, various colorimetric receptors consisting of gold and silver nanoparticles, metalloporphyrins, metal ion complexes, and pH-sensitive indicators are used in the array structure. By injecting a small volume of the urine sample, the color pattern of the sensor changes after 7 min, which can be observed visually. The color changes of the receptors (recorded by a scanner) are subsequently calculated by image analysis software and displayed as a color difference map. This study has been performed on 130 volunteers, including 60 patients infected by COVID-19, 55 healthy controls, and 15 cured individuals. The resulting array provides a fingerprint response for each category due to the differences in the metabolic profile of the urine sample. The principal component analysis-discriminant analysis confirms that the assay sensitivity to the correctly detected patient, healthy, and cured participants is equal to 73.3%, 74.5%, and 66.6%, respectively. Apart from COVID-19, other diseases such as chronic kidney disease, liver disorder, and diabetes may be detectable by the proposed sensor. However, this performance of the sensor must be tested in the studies with a larger sample size. These results show the possible feasibility of the sensor as a suitable alternative to costly and time-consuming standard methods for rapid detection and control of viral and bacterial infectious diseases and metabolic disorders.

Abstract
Emerging and relapsing infectious diseases pose a huge health threat to human health and a new challenge to global public health. Rapid, sensitive and simple diagnostic tools are keys to successful management of infectious patients and containment of disease transmission. In recent years, international research on Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-related proteins (Cas) has revolutionized our understanding of biology. The CRISPR-Cas system has the advantages of high specificity, high sensitivity, simple, rapid, low cost, and has begun to be used for molecular diagnosis and treatment of infectious diseases. In this paper, we described the biological principles, application fields and prospects of CRISPR-Cas system in the molecular diagnosis and treatment of infectious diseases, and compared it with existing molecular diagnosis methods, the advantages and disadvantages were summarized.

Abstract
The emergence of the COVID-19 pandemic prompted fast development of novel diagnostic methods of the etiologic virus SARS-CoV-2. Methods based on CRISPR-Cas systems have been particularly promising because they can achieve a similar sensitivity and specificity to the benchmark RT-qPCR, especially when coupled to an isothermal pre-amplification step. Furthermore, they have also solved inherent limitations of RT-qPCR that impede its decentralized use and deployment in the field, such as the need for expensive equipment, high cost per reaction, and delivery of results in hours, among others. In this review, we evaluate publicly available methods to detect SARS-CoV-2 that are based on CRISPR-Cas and isothermal amplification. We critically analyze the steps required to obtain a successful result from clinical samples and pinpoint key experimental conditions and parameters that could be optimized or modified to improve clinical and analytical outputs. The COVID outbreak has propelled intensive research in a short time, which is paving the way to develop effective and very promising CRISPR-Cas systems for the precise detection of SARS-CoV-2. This review could also serve as an introductory guide to new labs delving into this technology.

Abstract
The coronavirus disease 2019 (COVID‐19) is a global pandemic caused by a novel coronavirus called severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). To date, the virus has been detected in 219 countries of the world. Therefore, managing the disease becomes the priority, in which detecting the presence of the virus is a crucial step. Presently, real‐time RT polymerase chain reaction (RT‐qPCR) is considered a gold standard nucleic acid amplification test (NAAT). The test protocol of RT‐qPCR is complicated, places high demands on equipment, testing reagents, research personnel skills and is expensive. Therefore, simpler point‐of‐care (POC) tests are needed to accelerate clinical decision‐making and take some of the workload from centralized test laboratories. Various isothermal amplification‐based assays have been developed for the sensitive detection of different microorganisms, and recently some of them have been applied for detection of SARS‐CoV‐2. These do not require any programable thermocycler, can produce the results in a single temperature, and therefore, are considered simple. Unlike RT‐qPCR, these methods are highly sensitive, specific, less time‐consuming, simple and affordable, and can be used as POC diagnostic kit for COVID‐19. In this review, we have discussed the potential of isothermal amplification‐based assays as an alternative to RT‐qPCR for the detection of SARS‐CoV‐2.
