Práticas integrativas e complementares de saúde em Sergipe / Integrative and complementary health practices in Sergipe

A atenção primária em saúde (APS) é o primeiro nível de atenção em saúde, sendo um elo entre a população e o setor de saúde. Tem-se buscado a humanização dos atendimentos, e essa mudança, refletida pelas mudanças da sociedade, trouxe a implementação da Política Nacional de Práticas Integrativas e Complementares (PNPIC) no SUS. O objetivo deste trabalho foi realizar uma análise da tendência da quantidade das práticas integrativas e complementares realizadas nas regionais de saúde de Sergipe de 2017 a 2023, associando com a cobertura da atenção primária. Foi realizada análise de dados secundários através do Departamento de Informática do Sistema Único de Saúde (DATASUS), como forma de organização no período de junho/2015 a junho/2023 por regional de saúde de Sergipe. As análises dos dados foram descritivas e de correlação e por meio de análise de série temporal. A regional de saúde de Lagarto foi a que mais executou as práticas integrativas e complementares no período analisado e algumas regionais não tiveram continuidade na realização destas práticas. A regional de saúde com maior cobertura de APS foi Itabaiana. Não foi possível observar associação entre o número de práticas e a cobertura de atenção primária. Com o intuito de que o atendimento aos indivíduos seja cada vez mais humanizado, e em virtude da realização das práticas integrativas ter baixo índice ou descontinuidade em algumas regiões de Saúde de Sergipe, é relevante que os profissionais de saúde busquem conhecimentos sobre essas práticas, como também, os gestores em saúde incentivem esta ação.

Primary health care (PHC) is the first level of health care, being a link between the population and the health sector. The aim has been to humanize care, and this change, reflected by changes in society, has led to the implementation of the National Policy on Integrative and Complementary Practices (PNPIC) in the SUS. The objective of this work was to carry out an analysis of the trend in the number of integrative and complementary practices carried out in the health regions of Sergipe from 2017 to 2023, associating it with primary care coverage. Secondary data analysis was carried out through the Department of Informatics of the Unified Health System (DATASUS), as a form of organization from June/2015 to June/2023 by health region in Sergipe. Data analyzes were descriptive and correlational and through time series analysis. The Lagarto health region was the one that carried out the most integrative and complementary practices in the period analyzed and some regions did not continue to carry out these practices. The health region with the highest PHC coverage was Itabaiana. Observing an association between the number of practices and primary care coverage was impossible. With the aim that care for individuals is increasingly humanized, and because the implementation of integrative practices has a low rate or discontinuity in some Health regions of Sergipe, health professionals must seek knowledge about these practices as well as health managers encourage this action.

Enhancement of motor functional recovery in thoracic spinal cord injury: voluntary wheel running versus forced treadmill exercise.

JOURNAL/nrgr/04.03/01300535-202503000-00028/figure1/v/2024-06-17T092413Z/r/image-tiff Spinal cord injury necessitates effective rehabilitation strategies, with exercise therapies showing promise in promoting recovery. This study investigated the impact of rehabilitation exercise on functional recovery and morphological changes following thoracic contusive spinal cord injury. After a 7-day recovery period after spinal cord injury, mice were assigned to either a trained group (10 weeks of voluntary running wheel or forced treadmill exercise) or an untrained group. Bi-weekly assessments revealed that the exercise-trained group, particularly the voluntary wheel exercise subgroup, displayed significantly improved locomotor recovery, more plasticity of dopaminergic and serotonin modulation compared with the untrained group. Additionally, exercise interventions led to gait pattern restoration and enhanced transcranial magnetic motor-evoked potentials. Despite consistent injury areas across groups, exercise training promoted terminal innervation of descending axons. In summary, voluntary wheel exercise shows promise for enhancing outcomes after thoracic contusive spinal cord injury, emphasizing the role of exercise modality in promoting recovery and morphological changes in spinal cord injuries. Our findings will influence future strategies for rehabilitation exercises, restoring functional movement after spinal cord injury.

Analysis of ChatGPT Responses to Ophthalmic Cases: Can ChatGPT Think like an Ophthalmologist?

Objective: Large language models such as ChatGPT have demonstrated significant potential in question-answering within ophthalmology, but there is a paucity of literature evaluating its ability to generate clinical assessments and discussions. The objectives of this study were to (1) assess the accuracy of assessment and plans generated by ChatGPT and (2) evaluate ophthalmologists' abilities to distinguish between responses generated by clinicians versus ChatGPT. Design: Cross-sectional mixed-methods study. Subjects: Sixteen ophthalmologists from a single academic center, of which 10 were board-eligible and 6 were board-certified, were recruited to participate in this study. Methods: Prompt engineering was used to ensure ChatGPT output discussions in the style of the ophthalmologist author of the Medical College of Wisconsin Ophthalmic Case Studies. Cases where ChatGPT accurately identified the primary diagnoses were included and then paired. Masked human-generated and ChatGPT-generated discussions were sent to participating ophthalmologists to identify the author of the discussions. Response confidence was assessed using a 5-point Likert scale score, and subjective feedback was manually reviewed. Main Outcome Measures: Accuracy of ophthalmologist identification of discussion author, as well as subjective perceptions of human-generated versus ChatGPT-generated discussions. Results: Overall, ChatGPT correctly identified the primary diagnosis in 15 of 17 (88.2%) cases. Two cases were excluded from the paired comparison due to hallucinations or fabrications of nonuser-provided data. Ophthalmologists correctly identified the author in 77.9% ± 26.6% of the 13 included cases, with a mean Likert scale confidence rating of 3.6 ± 1.0. No significant differences in performance or confidence were found between board-certified and board-eligible ophthalmologists. Subjectively, ophthalmologists found that discussions written by ChatGPT tended to have more generic responses, irrelevant information, hallucinated more frequently, and had distinct syntactic patterns (all P < 0.01). Conclusions: Large language models have the potential to synthesize clinical data and generate ophthalmic discussions. While these findings have exciting implications for artificial intelligence-assisted health care delivery, more rigorous real-world evaluation of these models is necessary before clinical deployment. Financial Disclosures: The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Investigation on cost-effective composites for CO2 adsorption from post-gasification residue and metal organic framework.

Cost-effective CO2 adsorbents are gaining increasing attention as viable solutions for mitigating climate change. In this study, composites were synthesized by electrochemically combining the post-gasification residue of Macadamia nut shell with copper benzene-1,3,5-tricarboxylate (CuBTC). Among the different composites synthesized, the ratio of 1:1 between biochar and CuBTC (B 1:1) demonstrated the highest CO2 adsorption capacity. Under controlled laboratory conditions (0°C, 1 bar, without the influence of ambient moisture or CO2 diffusion limitations), B 1:1 achieved a CO2 adsorption capacity of 9.8 mmol/g, while under industrial-like conditions (25°C, 1 bar, taking into account the impact of ambient moisture and CO2 diffusion limitations within a bed of adsorbent), it reached 6.2 mmol/g. These values surpassed those reported for various advanced CO2 adsorbents investigated in previous studies. The superior performance of the B 1:1 composite can be attributed to the optimization of the number of active sites, porosity, and the preservation of the full physical and chemical surface properties of both parent materials. Furthermore, the composite exhibited a notable CO2/N2 selectivity and improved stability under moisture conditions. These favorable characteristics make B 1:1 a promising candidate for industrial applications.

Chronic cannabidiol treatment induces cardiovascular improvement in renovascular hypertensive rats.

BACKGROUND: Cannabidiol (CBD) is increasingly studied for its therapeutic potential in neurodegenerative diseases. Previous research on acute CBD administration has demonstrated cardiovascular benefits in hypertensive rats, including reduced mean blood pressure and oxidative stress. AIM: To investigate the long-term cardiovascular effects of chronic CBD treatment in renovascular hypertension induced by the 2-kidney-1-clip (2K1C) model. METHODS: Male Wistar rats (180-200 g, 8 weeks old) underwent 2K1C or SHAM surgery. Six weeks later, rats received chronic CBD treatment (20 mg/kg, twice daily for 14 days). A combination of ex vivo, in vitro, and in vivo methods was used to assess CBD's cardiovascular effects in 2K1C hypertensive rats. RESULTS: Chronic CBD treatment significantly reduced blood pressure and the depressor response to hexamethonium (a ganglionic blocker). It also normalized variability in low-frequency (LF) power and LF/high-frequency (HF) ratio. CBD enhanced vasodilation and reduced vasoconstriction in the mesenteric artery of 2K1C rats, accompanied by decreased expression of aortic reactive oxygen species (ROS). CONCLUSION: Our findings suggest that chronic CBD treatment exerts antihypertensive effects by improving baroreflex sensitivity and vascular function while decreasing arterial ROS levels and sympathetic nerve activity. These results underscore CBD's potential therapeutic role in managing cardiovascular complications associated with renovascular hypertension.

A Program to Optimize the Detection of Paroxysmal Atrial Fibrillation: The RITMO Study. / Programa para Otimizar a Detecção da Fibrilação Atrial Paroxística: Estudo Ritmo.

BACKGROUND: Atrial fibrillation (AF) is the most common sustained arrythmia, but still underdiagnosed especially among asymptomatic patients. OBJECTIVES: To evaluate a simple strategy to optimize the identification of AF. METHODS: Asymptomatic patients aged 65 years or older, with hypertension or heart failure (HF), were included. Data were inserted into the REDCap software platform. Patients were assessed for the risk for AF using the Stroke Risk Analysis (SRA) mathematical algorithm, which was applied on a one-hour electrocardiogram (ECG). All patients at high risk for AF were instructed to follow a home ECG protocol for seven days using a portable Kardia 6 (OMRON, AliveCor®). The Kolmogorov-test was used to test the normality of quantitative variables; those with normal distribution were expressed as mean and standard deviation. A p<0.05 was set as statistically significant. RESULTS: A total of 423 patients were assessed; 15 were excluded due to absence of SRA, yielding a sample of 408 patients. In 13 (3.2%), AF was identified, 120 (29.4%) were considered at high risk and 275 (67.4%) without increased risk for AF. Of the 120 high-risk patients, 111 successfully completed the seven-day protocol with Kardia; at least one episode of AF was identified in 43 patients. CONCLUSION: The strategy adopted in the RITMO study was shown to be effective in identifying AF in asymptomatic elderly patients with hypertension or HF, with an incidence of 13.7% (56/408).

FUNDAMENTO: A fibrilação atrial (FA) é a arritmia cardíaca sustentada mais frequente, mas ainda é subdiagnosticada especialmente em pacientes assintomáticos. OBJETIVO: Avaliar uma estratégia simples para otimizar a identificação da FA. MÉTODOS: Avaliados indivíduos assintomáticos com 65 anos ou mais, portadores de hipertensão arterial (HA) ou insuficiência cardíaca (IC). Os dados foram inseridos e armazenados em plataforma REDCap. Inicialmente foram realizadas análise de risco de FA com o algoritmo matemático Stroke Risk Analysis (SRA) aplicado em eletrocardiograma (ECG) de 1 hora. Todos os pacientes de alto risco de FA foram orientados a realizar o protocolo de ECG domiciliar por sete dias com o equipamento portátil Kardia 6L OMRON, AliveCor®. O teste de Kolmogorov-Smirnov foi usado para verificar a normalidade da distribuição das variáveis quantitativas; aquelas com distribuição normal foram expressas em média e desvio-padrão. Adotou-se como significativo o valor de p<0,05. RESULTADOS: Foram avaliados 423 pacientes; 15 foram excluídos por não terem realizado o SRA, resultando em uma amostra de 408 pacientes. A avaliação evidenciou que 13 (3,2%) pacientes apresentaram FA, 120 (29,4%) foram considerados de alto risco para FA e 275 (67,4%) sem risco aumentado. Dos 120 pacientes de alto risco, 111 realizaram adequadamente o protocolo de sete dias com o Kardia, tendo sido identificados um ou mais registros de FA em 43 pacientes. CONCLUSÃO: A estratégia adotada no estudo RITMO mostrou-se eficaz para identificar, com uma incidência de 13,7% (56/408), episódios de FA em pacientes idosos assintomáticos e portadores de HA ou IC.

Multiplex qPCR for the detection of bacteria associated with huanglongbing 'Candidatus Liberibacter asiaticus', 'Ca. L. americanus' and 16Sr IX group phytoplasma.

The occurrence of 'Candidatus Liberibacter' spp. and 'Ca. Phytoplasma' spp. associated with blotchy mottle symptoms poses challenges to huanglongbing (HLB) diagnosis using molecular techniques. The ability to detect multiple targets simultaneously and specifically is a key aspect met by qPCR. A set of primers and hydrolysis probes useful either in single or multiplex reactions for the detection and quantification of HLB-associated bacteria were developed. Sequences from conserved genes of the ribosomal proteins for Liberibacter and phytoplasma circumvent the lack of specificity and cross-reactivity problems related to 16S rDNA gene amplification, allowing precise and specific detection of HLB-associated bacteria in citrus and in the Liberibacter vector, Diaphorina citri. The triplex reaction exhibited high quality and precision as a robust tool for quantifying 'Ca. L. asiaticus' (CLas), 'Ca. L. americanus' (CLam) and 16SrIX phytoplasma. Triplex qPCR showed consistent results and comparable sensitivity to the RNR test, though Cq values were higher when compared to 16S rDNA qPCR. Detection tests using field samples indicate that the qPCR triplex can identify HLB-associated bacteria in samples with varying levels of symptoms, ranging from typical to asymptomatic. Assessment of field samples from growers indicated more than 78.6% had Cq lower than 35.0, below the cut-off established for qPCR reactions used in this work. qPCR triplex is a safe, specific, and sufficiently sensitive technique for detecting CLas, CLam and 16Sr IX phytoplasma simultaneously, in both citrus and D. citri samples. Its application is of importance in assisting growers in making decisions for HLB management.

Development of the machine learning model that is highly validated and easily applicable to predict radiographic knee osteoarthritis progression.

Many models using the aid of artificial intelligence have been recently proposed to predict the progression of knee osteoarthritis. However, previous models have not been properly validated with an external data set or have reported poor predictive performances. Therefore, the purpose of this study was to design a machine learning model for knee osteoarthritis progression, focusing on high validation quality and clinical applicability. A retrospective analysis was conducted on prospectively collected data, using the Osteoarthritis Initiative data set (5966 knees) for model development and the Multicenter Osteoarthritis Study data set (3392 knees) for validation. The analysis aimed to predict Kellgren-Lawrence grade (KLG) progression over 4-5 years in knees with initial KLG of 0, 1, or 2. Possible predictors included demographics, comorbidities, history of meniscectomy, gait speed, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores, and radiological findings. The Random Forest algorithm was employed for the predictive model development. Baseline KLG, contralateral knee osteoarthritis, lateral joint space narrowing (JSN) grade, BMI, medial JSN grade, and total WOMAC score were six features selected for the model in descending order of importance. Odds ratios of baseline KLG, contralateral knee osteoarthritis, and lateral JSN grade were 1.76, 2.59, and 4.74, respectively (all p < 0.001). The area-under-the-curve of the ROC curve in the validation set was 0.76 with an accuracy of 0.68 and an F1-score of 0.56. The progression of knee osteoarthritis in 4 ~ 5 years could be well-predicted using easily available variables. This simple and validated model may aid surgeons in knee osteoarthritis patient management.

DNA copy number profiles and systems biology connect chromatin remodeling and DNA repair in high-risk neuroblastoma.

Neuroblastoma (NB) is a solid tumor that accounts for 15% of all pediatric oncological deaths, and much is due to the low response to therapy in relapsed tumors. High-risk NB may present deletions in chromosome 11q, which may be associated with other chromosomal alterations and a poor response to therapy, but this association is still poorly understood. Using a systems biology network approach, we studied three patients with high-risk NB with deleted 11q stage 4 to highlight the connections between treatment resistance and copy number alterations in distinct cases. We built different protein-protein interaction networks for each patient based on protein-coding genes mapped at the cytobands pre- and post-chemotherapy from distinct copy number alterations data. In the post-chemotherapy networks, we identified five common regulatory nodes corresponding to the gained region located in ch17q:BIRC5, BRCA1, PRKCA, SUMO2, andGPS1. A crosslink between DNA damage and chromatin remodeling proteins was also found - a connection still poorly understood in NB. We identified a potential connection between XPB gain and chemoresistance of NB. The findings help elucidate the molecular profiles of high-risk NB with 11q deletion in pre- and post-chemotherapy tumor samples, which may reflect unique profiles in poor response to treatment.

Endonasal Thermal Imaging Before and After Nasal Airway Surgery.

OBJECTIVE: Nasal airway surgery is often applied when treatment fails to relieve nasal obstruction. However, surgery that improves airflow does not always alleviate the symptoms of nasal obstruction. The perception of nasal breathing is likely more related to changes in mucosal temperature than the mechanical sensation of flow or pressure. This study aims to measure intranasal mucosal temperature pre-and post-surgery using endonasal thermal imaging, exploring its correlation with subjective nasal breathing and objective airflow measurements. METHODS: A prospective study of adult patients with nasal obstruction managed with nasal airway surgery was performed. Intranasal mucosal temperatures were determined using the thermal endonasal image of the nasal passage produced by the infrared radiometric thermal camera (FILR VS290). A comparison was made between the mean values of mid-expiration (ExT) and mid-inspiration (InT) temperature data (internal nasal valve, nasal cavity, inferior turbinate, and overall airway [mean value]) and visual analog scale (VAS), Nasal Obstruction Symptom Evaluation (NOSE) scale and nasal airway resistance (NAR) before and after surgery. RESULTS: Seven patients (35.14 ± 16.45 years, 57.14% female) were included. All NOSE, VAS, and NAR improved after surgery (59.29 ± 10.89 vs 17.14 ± 14.64; P < .001, 64.50 ± 26.79 vs 18.57 ± 19.99; P < .001, 0.82 ± 0.48 vs 0.34 ± 0.11 Pa/cm3/s; P = .002, respectively). ExT, InT, and the difference between ExT and InT of three areas and overall airway were similar between pre-and post-surgery. No statistically significant correlations were found between intranasal mucosal temperature, VAS, NOSE, and NAR at pre-and post-surgery except for the difference between ExT and InT of overall airway and NOSE pre-operative (Pearson r = 0.57; 95% CI 0.06-1.09; P = .03). CONCLUSION: Endonasal thermal imaging can assess the intranasal mucosal temperature of a patient. However, more precise imaging of the nasal passages and data acquisition are required to establish mucosal temperature as an objective measure of nasal obstruction before and after nasal airway surgery in a clinical setting.

Exploring protein-protein interactions for the development of new analgesics.

The development of new analgesics has been challenging. Candidate drugs often have limited clinical utility due to side effects that arise because many drug targets are involved in signaling pathways other than pain transduction. Here, we explored the potential of targeting protein-protein interactions (PPIs) that mediate pain signaling as an approach to developing drugs to treat chronic pain. We reviewed the approaches used to identify small molecules and peptide modulators of PPIs and their ability to decrease pain-like behaviors in rodent animal models. We analyzed data from rodent and human sensory nerve tissues to build associated signaling networks and assessed both validated and potential interactions and the structures of the interacting domains that could inform the design of synthetic peptides and small molecules. This resource identifies PPIs that could be explored for the development of new analgesics, particularly between scaffolding proteins and receptors for various growth factors and neurotransmitters, as well as ion channels and other enzymes. Targeting the adaptor function of CBL by blocking interactions between its proline-rich carboxyl-terminal domain and its SH3-domain-containing protein partners, such as GRB2, could disrupt endosomal signaling induced by pain-associated growth factors. This approach would leave intact its E3-ligase functions, which are mediated by other domains and are critical for other cellular functions. This potential of PPI modulators to be more selective may mitigate side effects and improve the clinical management of pain.

Fresh Human Umbilical Cord Arteries as a Potential Source for Small-Diameter Vascular Grafts.

The demand for small-diameter vascular grafts has been globally increased but still lacks optimal solutions in this category. This study evaluated the feasibility of utilizing human pretreated fresh and nondecellularized umbilical cord arteries (hUCAs) as vascular grafts without needing any immunosuppression process. A mixed lymphocyte reaction assay revealed that hUCAs did not induce lymphocyte proliferation or cytokine production. To assess the in vivo inflammatory response, hUCAs were buried in fatty tissue under the skin of the abdominal wall in the left and right iliac fossas of rats. The average sizes of the implanted hUCAs remained consistent at 30 days post implantation. To evaluate xenogeneic transplantation, hUCAs were grafted to the abdominal aorta below the kidney of Wister rats. Remarkably, all rats exhibited positive revascularization and perfusion, maintaining blood pressure values of around 110/70 mmHg. Doppler ultrasound consistently indicated good circulation, with the three separate echogenic layers corresponding to the three arterial wall layers throughout the assessment period. Grafted rats exhibited normal motor behavior, accompanied by positive responses to thermal and pain stimulation. Blood biochemical values and whole blood cell counts showed no significant differences between pre and post-transplantation. Histological analysis of the grafts revealed no calcification or thrombosis, and a mild chronic inflammatory response was presented. In conclusion, hUCAs maintained their structural and functional properties after transplantation in rats without immunosuppression. This highlights their potential as a source for allogeneic, readily accessible, small-diameter vascular grafts.

OPAR: A Randomized Trial of Partial Breast Irradiation in Five Fractions Once Daily for Early Breast Cancer.

PURPOSE: Previous studies suggest that external-beam partial breast irradiation (PBI) delivered twice a day can lead to increased adverse cosmesis (AC). The objective of our trial was to determine whether two regimens for PBI given once daily over 1 week resulted in acceptable AC to inform a phase III trial. METHODS: Patients age ≥50 years with invasive breast cancer or ductal carcinoma in situ, ≤3 cm in size treated by lumpectomy with negative axillary nodes were randomly assigned to external-beam PBI of 30 Gy or 27.5 Gy, each given in five fractions once daily. The primary outcome was AC (fair or poor) by photographic assessment at 2 years. Secondary outcomes included AC assessed by nurse at 2 years, by patient self-assessment at 3 years, and late toxicity. On the basis of a 17% risk of AC with whole-breast irradiation, the upper bound of a two-sided 90% CI, 23% was set as the tolerance margin (OPAR, ClinicalTrials.gov identifier: NCT02637024). RESULTS: In total, 142 patients were randomly assigned to 30 Gy and 139 to 27.5 Gy. The median follow-up was 5 years. The mean age was 65 years, and the mean tumor size was 1.2 cm. Both schedules met acceptability criteria by photographic assessment (AC, 12.1% [90% CI, 8.2 to 17.6] for 30 Gy and 15.2% [90% CI, 10.8 to 21.1] for 27.5 Gy) and by nurse assessment. AC by patient self-assessment exceeded the 90% CI for the 30 Gy regimen. At 5 years, 16 (11.3%, 90% CI, 7.6 to 16.4) patients treated with 30 Gy and eight (5.8%, 90% CI, 3.3 to 9.9) patients treated with 27.5 Gy were observed to have grade 2 or more late toxicity. CONCLUSION: According to the study design, 30 Gy and 27.5 Gy resulted in acceptable cosmetic outcomes. In light of recent studies, a lower dose was chosen for the phase III trial.

Evaluating BTEX in vehicle exhaust gas: A fast and efficient approach using SPME and GC-BID.

Benzene, toluene, ethylbenzene, and the xylene isomers (m, p, and o-xylene) (BTEX) are known for their harmful effects on human health and have been extensively studied across various environmental matrices. However, quantifying BTEX in exhaust gases poses challenges due to the complexity of the matrices. In this study, we investigated a method development strategy involving solid-phase microextraction (SPME) and gas chromatography coupled with a dielectric barrier discharge ionization Detector (BID) for quantifying BTEX emitted from internal combustion engines operating at idle. Sampling was conducted using 1.0 L Tedlar bags, followed by withdrawal of aliquots and dilution with atmospheric air using a novel device (graduated vial) designed for gaseous samples. The SPME-GC-BID method was developed and validated for the conditions: BTEX extraction in CAR/PDMS 75 µm fiber at a contact time of 5.0 min at a temperature of 27 °C, followed by GC-BID analysis. Method validation to ensure the reliability of quantitative results used the merit figures e.g., limits of detection (LOD) and quantification (LOQ), precision, and accuracy (recovery). LOD varied from 0.194 to 0.340 mg m-3, LOQ varied from 0.587 to 1.03 mg m-3, precision ranged from 1.47 to 7.14 %, and recovery varied from 82.34 to 109.5 %. BTEX concentration in vehicle exhaust varied from 3.40 to 16.4 mg m-3. The results showed, concerning the figures of merit analyzed, that the SPME-GC-BID method provides good sensibility, precision, and accuracy for evaluating the presence of BTEX in the exhaust of internal combustion engines, contributing to the understanding of health risks associated with vehicle emissions.

IL36RN Mutations and Correlated Characteristics in Generalized Pustular Psoriasis Patients in Can Tho City, Vietnam: A Cross-sectional study.

INTRODUCTION: Pustular psoriasis is a rare and severe form of psoriasis characterized by sterile pustules on an erythematous background. The disease ranges from localized to generalized forms, with the latter being particularly life-threatening and recurrent. Understanding the genetic basis of pustular psoriasis, particularly IL36RN mutations, is crucial for developing better treatments. This study aims to determine the prevalence and types of IL36RN gene mutations and their relationship with clinical and paraclinical features in patients with pustular psoriasis in Can Tho City, Vietnam. METHODS: A cross-sectional study was conducted at Can Tho Dermatology Hospital involving 59 patients diagnosed with generalized pustular psoriasis (GPP) according to ERASPEN and Japanese Dermatological Association criteria. Data on demographic, clinical, and laboratory characteristics were collected. IL36RN gene mutations were identified through genomic DNA sequencing. Statistical analyses were performed to explore associations between IL36RN mutations and clinical features. RESULTS: The study included 59 participants, predominantly female (69.5%), with an average age of 39.12 years. A significant proportion (83.1%) had a history of psoriasis, with frequent recurrences (94.9%). The most common IL36RN mutation identified was p.Arg10ArgfsX1, present in 44.1% of patients. Other mutations included p.Pro76Leu (20.3%) and p.Arg102Trp (1.7%). Patients with IL36RN mutations were younger and had an earlier disease onset. Significant associations were found between IL36RN mutations and clinical features such as fever (OR = 11, p < 0.0001) and geographic tongue (OR = 14.67, p < 0.0001). CONCLUSION: Our study reveals a high prevalence of IL36RN mutations, particularly p.Arg10ArgfsX1, in Vietnamese pustular psoriasis patients, strongly associating these mutations with clinical features like fever and geographic tongue.
