ABSTRACT
Abstract Field survey study was conducted season (2017). Soybeans and weeds were weekly sampled randomly. Thrips adults were identified and counted. Detection of the virus isolate and the natural incidence was determined using; Mechanical transmission, host range, DAS-ELISA, RT-PCR. The natural incidence thrips individuals was detected depending on the SVNV% in thrips individuals and weeds hosts. Ten thrips species were associated with soybean plants in the field. The most abundant species was T. tabaci, average 256.5 average no.of individuals, followed by F. occidentalis (142.5 average no. of individuals), then N. variabilis (86.6/ average no. of individuals). Fourteen thrips species occurred on 5 legumes field crops and 41 weed plant species within soybean field. The highest average number 40.6.of individuals were recorded on Ammi majus. While the lowest one 3.3 average no. of individuals were on Urtica urens. Only 21diagnostic plant species were susceptible to infection with SVNV. G. max and Vigna radiate, were the highest percentage of infection 80% followed by V. unguilata & N. benthamiana, 75%. Egyptian isolate of Soybean vein necrosis virus (SVNV) in this study showed a high degree of similarity and it is closely related to TSWV from Egypt (DQ479968) and TCSV from USA (KY820965) with nucleotide sequence identity of 78%. Four thrips species transmitted SVNV (F. fusca 4.0%, F. schultzei 4.3%, F. tritici 3.3% and N. variabilis 68.0% transmission). Both C. phaseoli and M. sjostedti can acquire the virus but unable to transmit it. The following species; T. tabaci, F. occidentalis, S. dorsallis and T. palmi cannot acquire or transmit SVNV. The incidence of SVNV in the field started by the end of July then increased gradualy from 12.7 to 71.3% by the end of the season. In conclusion, few thrips individuals invaded soybean crops are enough to transmit high rate of SVNV within the crop. Furthermore, several vector species are also abundant on weeds, which are the major sources of soybean viruses transmitted to the crops. This information might be important for control and reduce the incidence of SVNV infection.
Resumo O estudo de pesquisa de campo foi realizado na temporada (2017). A soja e as ervas daninhas foram amostradas semanalmente de forma aleatória. Tripes adultos foram identificados e contados. A detecção do vírus isolado e a incidência natural foram determinadas usando transmissão mecânica, gama de hospedeiros, DAS-ELISA, RT-PCR. A incidência natural de tripes em indivíduos foi detectada dependendo da % de SVNV em tripes e hospedeiros infestantes. Dez espécies de tripes foram associadas a plantas de soja no campo. A espécie mais abundante foi T. tabaci, com média de 256,5 número médio de indivíduos, seguida por F. occidentalis (142,5) e N. variabilis (86,6 / número médio de indivíduos). Catorze espécies de tripes ocorreram em 5 culturas de leguminosas e 41 espécies de plantas daninhas dentro de campos de soja. O maior número médio de 40,6 indivíduos foi registrado em Ammi majus. Enquanto o mais baixo, 3,3 número médio de indivíduos, foi no Urtica urens. Apenas 21 espécies de plantas diagnosticadas foram suscetíveis à infecção com SVNV. G. max e Vigna radiate foram os maiores percentuais de infecção, 80%, seguidos por V. unguilata e N. benthamiana, 75%. O isolado egípcio neste estudo mostrou um alto grau de similaridade e está intimamente relacionado ao TSWV do Egito (DQ479968) e ao TCSV dos EUA (KY820965), com identidade de sequência de nucleotídeos de 78%. Quatro espécies de tripes transmitiram SVNV (F. fusca 4,0%, F. schultzei 4,3%, F. tritici 3,3% e N. variabilis 68,0% de transmissão). Tanto C. phaseoli quanto M. sjostedti podem adquirir o vírus, mas não podem transmiti-lo. As seguintes espécies, T. tabaci, F. occidentalis, S. dorsallis e T. palmi não podem adquirir ou transmitir SVNV. A incidência de SVNV no campo, iniciada no final de julho, aumentou gradativamente de 12,7 para 71,3% no final da temporada. Em conclusão, poucos indivíduos de tripes invadiram a cultura da soja e são suficientes para transmitir alta taxa de SVNV dentro da cultura. Além disso, várias espécies de vetores também abundam em ervas daninhas, que são as principais fontes dos vírus da soja transmitidos às lavouras. Essas informações podem ser importantes para controlar e reduzir a incidência de infecção por SVNV.

@#Introduction: Previous studies have suggested that young individuals with type 2 diabetes mellitus (T2DM) face challenges in achieving optimal diabetes self-management, leading to difficulties in attaining the recommended glycaemic target. The reasons behind these suboptimal practices remain unclear due to the limited number of studies conducted in Malaysia that focused on diabetes self-management among young people. This qualitative study aimed to understand the lived experience of young people with T2DM on self-management in Malaysia. Methods: Young people at the age of 10 to 24 years, who had been diagnosed with T2DM and the caregivers who managing young people with T2DM were interviewed. Data were thematically analysed with the aid of QSR NVivo version 12. Results: Sixteen young informants and eleven caregivers participated in this study. Three major themes conceptualised the lived experience of diabetes self-management: (1) the trajectory to T2DM diagnosis; (2) perceived causes of T2DM; (3) the efforts in diabetes self-management. The route of diagnosis and experiential knowledge about T2DM might determine their efforts in the self-management among the young people. Healthy eating, medication taking and physical activity were perceived as important tasks in diabetes self-management. The involvement of the caregivers in diabetes self-management evolved over time. Conclusion: The study highlighted the experience of young people and caregivers since the beginning of the diagnosis and their strategies in diabetes self-management. More understanding of the lived experiences of patients and caregivers in disease management within the socio-ecological context could help to improve health-care services and intervention for this population.
ABSTRACT
In the past decade, the rate of cesarean sections has doubled leading to the more frequent occurrence of cesarean-related complications. Cesarean scar site diverticulum or isthmocele is one such complication that is defined as an outpouching of the anterior uterine wall at the cesarean scar site in continuity with the endometrial cavity, creating a wedge-shaped defect of variable depth. We report a case of a middle-aged female with secondary infertility for the last 11 years with one live issue 12 years back through a cesarean section at term. She had undergone an array of investigations for infertility for the past 5 years. She was diagnosed as having an isthmocele and managed with surgical repair of the defect at our hospital with subsequent assisted conception 8-month post-surgical repair. The importance of diagnosing a cesarean scar diverticulum cannot be understated not only because it is a surgically treatable cause of infertility but also because if such patients conceive, they may land in uterine rupture, placenta accreta, or scar ectopic pregnancy which can complicate into life-threatening situations.
ABSTRACT
Background: Breast Imaging Reporting and Data System (BI?RADS) classification for breast lesions was proposed for uniformity in categorizing breast lesions. While BI?RADS 1, 2 and 4–6 categories are straightforward, BI?RADS 3 is an intermediate category lesion with significantly different meanings and findings for mammography, ultrasound, and magnetic resonance imaging and is diagnostically challenging. Our study aims to determine the frequency and the malignancy rate of BI?RADS category 3 lesions detected on ultrasound breast and digital X?ray mammography by doing follow?ups at 6, 12, and 24 months of imaging. Materials and Methods: This ambispective study was conducted in the Department of Radiodiagnosis, Jawaharlal Nehru Medical College and Hospital, Aligarh Muslim University, Aligarh, from October 2020 to October 2022, which included 55 patients referred for digital X?ray and breast ultrasound. All BI?RADS category 3 in the initial sonomammography and digital X?ray mammography were included in the study and were followed up for final diagnosis and outcome either by pathological analysis or follow?up using sonomammography and digital X?ray mammography for a maximum of 24 months. Results: Fifty?five patients were categorized into the benign or malignant category from the results of tissue diagnosis or via follow?up. Fifty?four patients (98.18%) showed benign lesions, and one (1.82%) got malignant lesions. In the majority, 31 (56.36%) patients, the mean follow?up time was 6 months, followed by 12 months 10 (18.18%). Follow?up was 24 months in only 1 out of 55 patients (1.82%). The mean value of time to follow?up (months) of study subjects was 6 ± 4.6 with a median (25th–75th percentile) of 6. Conclusion: Short?term interval follow?up in BI?RADS category: three patients are enough to detect early breast malignancy, and this will avoid unnecessary tissue diagnosis (invasive procedure) in benign lesions. In our study, the malignancy yield in the follow?up of BI?RADS 3 was 1.82% (<2%).
ABSTRACT
A 26-year-old Malaysian woman (childbearing age) attended a private primary care clinic with a known case of gastroesophageal reflux disease (GERD) and complained of persistent nausea and a few episodes of vomiting. She had no known drug allergy, no surgical history, no hospitalization in the last two years, was a non-smoker, and no history of drug or alcohol abuse. The patient was prescribed Tab metoclopramide 10 mg TDS and Tab ranitidine 150 mg BD for five days. About 30 min after oral administration of both medicines, her eyes rolled involuntary upward, leading to lateral deviation of the eyes, and mouth jaws clenched as if “dislocated jaws.” The patient was immediately brought into an emergency department (ED) of a public tertiary care hospital. A drug challenge test was done which resulted in the withdrawal of metoclopramide. The accompanied sister later disclosed that the patient had taken metoclopramide and ranitidine from a private clinic earlier in the day. The patient self-assumed to have a sudden seizure, due to excessive hot weather and dehydration. A slow intravenous infusion of 50 mg/mL diphenhydramine hydrochloride in 0.9% w/v NaCl 100 mL was administered stat. Consequently, the symptoms vanished after approximately 30 min of the therapy, devoid of relapse. The patient was discharged from ED post 8 hours of monitoring with complete recovery. Physicians frequently prescribe metoclopramide to treat nausea and vomiting, which may cause adverse drug reaction of acute dystonic oculogyric crisis (OGC). Due to its unwanted and unpredictable extrapyramidal symptoms, metoclopramide should be prescribed and dispensed with caution. Thorough history taking at ED is imperative for correct early diagnosis and treatment, as metoclopramide-induced dystonic OGC has a high probability of confusion with other causes of dystonia such as conversion and seizures, encephalitis, tetanus, and hypercalcemic tetany.
ABSTRACT
@#Autoimmunity associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has been well-described as the mechanism of development of thyroid dysfunction following Coronavirus Disease 19 (COVID-19) infection and SARS-CoV-2 vaccination. However, the occurrence of thyroid eye disease (TED) after SARS-CoV-2 vaccination is scarcely described. The postulated mechanisms include immune reactivation, molecular mimicry and the autoimmune/inflammatory syndrome induced by adjuvants (ASIA). We report a case of new-onset TED after receiving the SARSCoV- 2 vaccine.

Purpose@#This study aimed to evaluate the anatomic circle around the impacted lower third molar to show, document,and correlate essential findings that should be included in the routine radiographic assessment protocol as clinically meaningful factors in overall case evaluation and treatment planning. @*Materials and Methods@#Cone-beam computed tomographic images of impacted lower third molars were selected according to specific inclusion criteria. Impacted teeth were classified according to their position before assessment. The adjacent second molars were assessed for distal caries, distal bone loss, and root resorption. The fourth finding was the presence of a retromolar canal distal to the impaction. Communication with the dentist responsible for each case was done to determine whether these findings were detected or undetected by them before communication. @*Results@#Statistically significant correlations were found between impaction position, distal bone loss, and detected distal caries associated with the adjacent second molar. The greatest percentage of undetected findings was found in the evaluation of distal bone status, followed by missed detection of the retromolar canal. @*Conclusion@#The radiographic assessment protocol for impacted third molars should consider a step-by-step evaluation for second molars, and clinicians should be aware of the high prevalence of second molar affection in horizontal and mesioangular impactions. They also should search for the retromolar canal due to its associated clinical considerations.(Imaging Sci Dent 2023; 53: 137-44)
ABSTRACT
@#Introduction: Due to the increasing rate of drug prices and overall healthcare inflation, stakeholders from the pharmaceutical industry and non-governmental organisations (NGOs) are voicing their concerns about the possible reciprocal effects in the long run. Drug price controls (DPCs) regulation is crucial to ensure affordability and indirectly reduce congestion in public healthcare facilities. This study aims to identify the SWOT analysis of the DPCs in Malaysia and how it will impact the drug supply chain. Methods: The study adopted a subjective environmental scanning method and a SWOT analysis tool to examine the Malaysian pharmaceutical DPCs in the healthcare supply chain (HSC) ecosystem through both intrinsic and extrinsic perspectives. Results: The immediate effect of DPCs would be beneficial, especially to the patients and the government. Balancing the right amount of control and liberalization of the market is seen to be the biggest factor contributing to the policy’s effect on the drug supply chain. The main concern would be the long-term effect as mixed results are coming from a group of countries that had implemented a similar policy. Conclusion: Notwithstanding the qualitative methodology of the paper, the findings could provide a better understanding of the price of drugs in Malaysia’s HSC and serve as a foundation for future studies. This paper proposes a new way to diversify the DPCs economy by entering the HSC chain industry.
ABSTRACT
@#Medical implants are normally used in clinical practice to treat most orthopaedics situations involving bone fractures, deformities, dislocation, and lengthening. It should be noted that specific measures regarding biomechanical and biomaterial characteristics are required for a successful post-surgery procedure. Biomechanical evaluations on the medical implants could be performed by utilising computer and engineering technology. One of them is in silico studies using finite element method that could be simulated in high-performance computer. However, various assumptions are required in computer simulation, such as the constraints on data input and computer resources. This review paper discusses current approaches of constructing a finite element model of human bone with specific material properties for upper limb such as the shoulder joint, humerus, elbow joint, radius and wrist joint. Previous related literatures were reviewed from selected keywords and search engines. To narrow the literature search in this study, inclusion and exclusion criteria of the literature searching were applied. We looked at the current level of knowledge in this field and offered recommendations for future study. In conclusion, studies from previous literature have demonstrated several ways for developing mathematical models and simulating medical implants.
ABSTRACT
@#This manuscript aims to examine depression and the relationship between depression and other comorbidity diseases among women involved in prostitution in Kuala Lumpur. A total of 126 women were interviewed face to face using a structured questionnaire. The M.I.N.I Neuro-Psychiatric Interview Diagnostic Test Tool 6.0 Bahasa Malaysia Version was used to measure depression among women involved in prostitution in Kuala Lumpur. Meanwhile other comorbidity diseases were measured based on the women’s infectious disease status such as Sexually Transmitted Diseases, Hepatitis, HIV and AIDS. The results of study were analysed using SPSS software version 21. Descriptive tests were used to determine the status of depression among women involved in prostitution. The Chi-square test was used to identify the relationship between the status of other comorbidity diseases and depression among women involved in prostitution. The results of the descriptive analysis revealed that 92 out of the 126 women who were interviewed reported suffering from depression. In fact, the results of Chi Square test (p≤0.05) analysis showed that there was a significant relationship between the status of other comorbidity diseases especially Hepatitis C and depression among women involved in prostitution in Kuala Lumpur. The findings of the study indicated that women s who were positive with Hepatitis C were more prone to report depressive disorders. Therefore, mental health education program and treatment specially for women involved in prostitution need to be integrated into the prevention programs of the infectious diseases.
ABSTRACT
@#Melioidosis is endemic in Southeast Asia, including Malaysia. Liver abscess is not uncommon in melioidosis, but it is usually associated with bacteremia. We presented a case of a 55-year-old gentleman with underlying end-stage renal failure who presented with non-specific abdominal pain for three months. Initial blood investigations showed leukocytosis and increased C-reactive protein. Computed tomography (CT) of the abdomen revealed multiple hypodense lesions in the liver and spleen. The culture of the liver specimen obtained through the ultrasound-guided isolated Burkholderia pseudomallei. He was given an adjusted dose of intravenous ceftazidime due to underlying renal failure. Melioidosis serology also returned positive for IgM with titer >1:1280. His blood cultures were reported negative three times. Despite on antibiotics for five weeks, there was no significant improvement of the liver abscesses was observed. He was unfortunately infected with the SARS-CoV-2 virus during his admission and passed away due to severe COVID-19 pneumonia.
ABSTRACT
@#Vibrio cholerae is a gram-negative bacterium synonymous with its namesake disease, cholera. Thus, gastrointestinal symptoms are the norm and V. cholerae is very rarely associated with skin and soft tissue infections. We describe a case of a 63-year-old Chinese woman with multiple medical comorbidities on corticosteroid therapy who developed fever and a painful swelling on her left leg after being pricked by a branch while gardening. There was no abdominal pain, vomiting or diarrhea. A diagnosis of bullous cellulitis was made clinically, and blood was sent for bacteriological culture. A beta-hemolytic commashaped gram-negative bacillus was isolated from the blood. It was also oxidase-positive and produced an acid/alkaline (A/K) reaction on triple sugar iron agar. It was identified biochemically as Vibrio cholerae. After additional testing, it was found to be of the O1 serogroup and Ogawa serotype. The infection resolved following a 10-day course of high-dose co-trimoxazole therapy.
ABSTRACT
@#Mycotic aneurysm is one of the extra-intestinal manifestations of Salmonella Enteritidis infection. The diagnosis of this condition is challenging owed to its variation in clinical presentations. We presented a case of a 54-year-old man with underlying diabetes mellitus and chronic smokers presented with acute right flank pain and fever associated with mild jaundice. The initial laboratory investigations suggested features of obstructive jaundice and urinary tract infection. The contrast enhancing computed tomography of the abdomen revealed the presence of saccular mycotic aneurysm located at the infrarenal abdominal aorta. The blood culture grew Salmonella Enteritidis which was susceptible to ceftriaxone, trimethoprim-sulfamethoxazole, ciprofloxacin, ampicillin, and amoxicillin-clavulanic acid. Intravenous ceftriaxone was initiated, and he underwent open surgery and artery repair at day 8 of admission. He responded well to the treatment given and subsequently discharged home after completed three weeks of intravenous ceftriaxone.
ABSTRACT
Lespedeza cuneata (LC) is a perennial plant used in herbal medicine to treat numerous diseases, including prostatic hyperplasia, diabetes, early atherosclerosis, and hematuria. Reference collections of bioactive compounds of LC are crucial for the determination of their pharmacological properties. However, little is known regarding its anti-oxidative and anti-inflammatory effects in alveolar macrophage (MH-S) cells. This study examined whether LC can inhibit reactive oxygen species and Coal fly ash (CFA) induced inflammation in MH-S cells. The anti-oxidative effects of LC were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays, anti-inflammatory effects were examined using nitric oxide (NO) assay, and cytotoxicity was analyzed using methyl thiazolyl tetrazolium assay. The expression of inflammatory cytokine genes was assessed through a reverse-transcription polymerase chain reaction. Our results revealed that LC exhibited high radical scavenging activity and a dose-dependent (7.8–1,000 μg/mL) inhibition of oxidation as compared to ascorbic acid and Trolox. It also inhibited CFA-induced NO production in MH-S cells. Moreover, it suppressed the CFA exposure-mediated expression of pro-inflammatory mediators and cytokines, including inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin (IL)-1β, IL-6, and tumor necrosis factor-α. These results suggest that LC is a potent antioxidant and anti-inflammatory agent that can be useful as a nutraceutical product.
ABSTRACT
Abstract Introduction Disease phobia may impose distressing manifestations along with compromised quality of life, particularly in young age. COVID-19 caused substantial psychological concerns in general population which required the attention of health authorities to address the issue as soon as possible. Objective This study was aimed to determine COVID-19 phobia in Pakistani youth during the current pandemic. Method A cross-sectional study was conducted to ascertain the extent of fear of COVID-19 among university students in Lahore, Pakistan using the COVID-19 Phobia Scale (C19P-S). Psychological, somatic, social, and economic factors were ascertained among students. The relationship of demographics with the phobia score was determined through appropriate statistical tests. Result This study included 374 students with a male preponderance (64.7%). The mean C19P-S score was 59.08 ± 14.44 (IQR: 50 - 70), with no significant difference among demographics except gender (male 57.65 ± 14.77 vs female 61.70 ± 13.47; p = .009). The mean psychological, psycho-somatic, economic, and social subscale scores were 19.59 ± 5.00 (25th percentile = 16 and 75th percentile = 24), 12.29 ± 4.56 (25th percentile = 10 and 75th percentile = 15), 11.22 ± 3.67 (25th percentile = 8 and 75th percentile = 14) and 15.97 ± 4.04 (25th percentile = 13.75 and 75th percentile = 19), respectively. Male students had a significantly lower score on social and psychological subscales than females (p< .05). Discussion and conclusion One fourth of the students achieved a fear score > 70 on C19P-S. These results indicate the need of dire maneuvers for reducing corona-phobia among university students.

Objetivo Este estudio buscó determinar la fobia al COVID-19 en jóvenes paquistaníes durante la pandemia actual. Método Se realizó un estudio transversal basado en la web para evaluar el miedo al COVID-19 entre los estudiantes universitarios en Lahore; para esto se utilizó la Escala de Fobia COVID-19 (C19P-S). Se evaluaron factores psicológicos, somáticos, sociales y económicos entre los estudiantes. La relación de la demografía con la puntuación de fobia se determinó mediante pruebas estadísticas apropiadas. Resultados Este estudio incluyó a 374 estudiantes con preponderancia masculina (64.7%). La puntuación media de C19P-S fue 59.08 ± 14.44 (IQR: 50 - 70), sin diferencias significativas entre los datos demográficos, excepto el género (hombres 57.65 ± 14.77 versus mujeres 61.70 ± 13.47; p = .009). Las puntuaciones medias de las subescalas psicológicas, psicosomáticas, económicas y sociales fueron 19.59 ± 5.00 (percentil 25 = 16 y percentil 75 = 24), 12.29 ± 4.56 (percentil 25 = 10 y percentil 75 = 15), 11.22 ± 3.67 (percentil 25) = percentil 8 y 75 = 14) y 15.97 ± 4.04 (percentil 25 = 13.75 y percentil 75 = 19), respectivamente. Los estudiantes varones obtuvieron una puntuación significativamente menor en las subescalas sociales y psicológicas que las mujeres (p< .05). Discusión y conclusión Una cuarta parte de los estudiantes obtuvo una puntuación de miedo > 70 en la C19P-S. Estos resultados indican la necesidad de aplicar medidas extremas para reducir la fobia al Coronavirus entre los estudiantes universitarios.
ABSTRACT
Objective To determine the effects of deoxyelephantopin on mTOR and its related target molecules (Akt/mTOR/P70S6K) in the ER-positive breast cancer cell line. Materials and Methods Primary in silico simulations were determined, and the effects of deoxyelephantopin on the phosphorylation of the Akt/mTOR/P70S6K molecules were evaluated using AlphaScreen-based assays and western blot analysis, respectively. Results Based on the estimated FEB and Ki values, deoxyelephantopin appeared to have a stronger affinity toward P70S6K as compared with Akt and mTOR. Both deoxyelephantopin and control inhibitors were observed to form hydrogen bonds with the same key residue, Leu175 of the P70S6K molecule. Deoxyelephantopin downregulated the p P70S6K protein expression significantly from 18 µM (p < 0.05) and onward. Based on the AlphaScreen assay, deoxyelephantopin produced a concentration-dependent inhibition on the phosphorylation of P70S6K with an IC50 value of 7.13 µM. Conclusion Deoxyelephantopin induced cell death in MCF-7 cells possibly via DNA fragmentation, inhibition of the phosphorylation of P70SK6, and downregulation of the relative p-p70S6K protein expression levels.
ABSTRACT
Vector borne diseases (VBDs) remain one of the greatest dangers to global health. At least seven VBDs of public health concern are prevalent in Egypt, including schistosomiasis, fascioliasis, lymphatic filariasis, leishmaniasis, malaria, dengue, and Rift Valley fever. Although many of these diseases are preventable by using evidence-based protective measures, VBD expansion patterns over the past few decades pose a significant challenge for modern parasitology and tropical medicine. In their action plan, Egypt did not identify populations at risk of VBDs. Egypt intends to improve its regional and international communication to identify pathogens and infections and develop “One Health”- compliant preparedness and prevention strategies. However, cross-border collaborations are required for the control of VBDs. In this context, we provide a situational analysis and comprehensive review of the epidemiological data on Egypt’s most prevalent VBDs based on an exhaustive search of the major electronic databases and literature from 1950 to 2019. We identified the gaps in Egypt’s preparedness for vector-borne disease threats, including adaptation documents, surveillance and monitoring, environmental management, and preparations for the health system. There is a lack of implementation of an integrated vector management strategy that integrates chemical, environmental, and biological control as well as health education. This necessitates cross-sectoral coordination and community involvement to improve vector control activities and the use, storage, and disposal of pesticides.
ABSTRACT
Background: Lichen planus (LP) is an idiopathic, chronic, relapsing, inflammatory, autoimmune dermatological disease. The etiopathogenesis of LP is still unclear. Autophagy is a strictly regulated lysosomal degradation pathway that is crucial for maintaining intracellular homeostasis and normal development. The dysregulation of autophagy-associated genes was recognized to increase the susceptibility to multiple diseases, including inflammation, autoimmune disorders and cancer. Aims: Our study aimed to detect the expression of autophagy-related gene 9 b (ATG9B) in LP patients compared to normal control persons to investigate the possible role of autophagy in pathogenesis of this disease. Methods: This case–control study included 30 LP patients and 30 age-, gender-matched healthy controls. Four millimeters punch skin biopsies were obtained from LP lesions and from the controls and they were kept in lysis solution for the stability of the studied parameters and were kept frozen at –80°C till analysis of ATG9B using real-time polymerase chain reaction. Results: The level of ATG9B in lesional skin of LP was significantly decreased compared to normal control persons (P < 0.01); also, there was a non-significant relation between ATG9B level and age, sex, duration and family history among LP patients. Limitations: Limited number of patients included in our study (30 patients). Conclusion: Autophagy may play a role in the pathogenesis of cutaneous LP.
