RESUMO

BACKGROUND: Therapeutic apheresis (TA) is already used to treat various diseases in the field of nephrology. The aim of this study was to evaluate the frequency and types of complications that occur during TA in children with kidney disease. METHODS: Records of children (≤ 18 years) who underwent TA between 2007 and 2022 were retrospectively reviewed. Children with missing data and those with a diagnosis of nonnephrological disease were excluded. RESULTS: A total of 1214 TA sessions, including 1147 therapeutic plasma exchange (TPE) sessions and 67 immunoadsorption (IA) sessions, were performed on the 108 patients enrolled in the study. Forty-seven percent of the patients were male, and the mean age was 12.22 ± 4.47 years. Posttransplant antibody-mediated rejection (64.8%) and hemolytic uremic syndrome (14.8%) were the most common diagnoses indicating TA. Overall, 17 different complications occurred in 58 sessions (4.8%), and 53 sessions (4.6%) were not completed because of these complications. The distribution of complications among the patients was as follows: 41.4% had technical complications, 25.9% had allergic complications, and 32.7% had others. The most common technical complication was insufficient flow (37.5%). The incidence of complications was greater in patients aged 3-6 years than in patients in the other age groups (p = 0.031). The primary disease, type of vascular access, and rate of fresh frozen plasma/albumin use were similar between patients with and without complications (p values of 0.359 and 0.125 and 0.118, respectively). CONCLUSIONS: Our study showed that complications occurred in only 4.8% of TA sessions. The most common complication was technical problems.

RESUMO

PURPOSE: Develop a spectroscopic method to assess cartilage thickness during the arthroscopic examination. METHODS: Currently, arthroscopy assesses cartilage damage visually; outcomes are based on the surgeon's subjective experience. Light reflection spectroscopy is a promising method for measuring cartilage thickness based on the absorption of light by the subchondral bone. In the presented study, in vivo diffuse optical back reflection spectroscopic measurements were acquired by gently placing an optical fibre probe on different locations of the articular cartilage of 50 patients during complete knee replacement surgery. The optical fibre probe consists of two optical fibers with a diameter of 1 mm to deliver the light and detect back-reflected light from the cartilage. Centre to centre distance between the source and the detector fibers was 2.4 mm. Actual thicknesses of the articular cartilage samples were measured under microscopy using histopathological staining. RESULTS: Using half of the samples in the patient data, a linear regression model was formed to estimate cartilage thicknesses from the spectroscopic measurements. The regression model was then used to predict the cartilage thickness in the second half of the data. The cartilage thickness was predicted with a mean error of 8.7% if the actual thickness was less than 2.5 mm (R2 = 0.97). CONCLUSION: The outer diameter of the optical fibre probe was 3 mm, which can fit into the arthroscopy channel and can be used to measure the cartilage thickness in real-time during the arthroscopic examination of the articular cartilage.

RESUMO

Cervical carcinogenesis is the leading cause of cancer-related deaths in women, and the role of high-risk human papillomavirus (HR-HPV) as a possible risk factor in the development of this cancer is well recognized. Despite the availability of multi-therapeutic approaches, there is still major concern regarding the prevention of metastatic dissemination and excessive tissue injuries. Therefore, it is imperative to develop a safer and more efficient treatment modality. Ficus carica, a natural plant, has shown potential therapeutic properties through its fruit latex when applied to HPV-positive cervical cancer cell lines. However, the mechanisms of action of Ficus carica (fig) latex are not well understood. This study aims to provide a deeper insight into the biological activities of fig latex on human cervical cancer cell lines expressing high-risk HPV types 16 and 18. The data obtained from this study reveal that fig latex influences the expression of genes involved in "Class I MHC-mediated antigen presentation" as well as "Antigen processing: Ubiquitination and Proteasome degradation". These genes play a crucial role in host immune surveillance and the resolution of infection. Notably, Western blot analysis corroborated these findings, demonstrating an increase in the expression of MHC class I in HeLa cells after fig latex treatment. Findings from this study suggest that fig latex may enhance T cell responses against oncogenic HPV, which could be beneficial for the clearance of early-stage cancer.

RESUMO

INTRODUCTION: The purpose of this study was to determine the predictive and prognostic factors for COVID-19 infection and its relationship with human leukocyte antigen (HLA) in kidney transplant recipients. MATERIAL AND METHOD: Three hundred fifty kidney transplant recipients were included in the study. Recipients were divided into two groups: COVID-19(+) (n = 100) and control (n = 250). The relationships between HLA frequencies, COVID-19 infection, and prognostic factors (age, donor type, immunosuppression protocol, etc.) were then evaluated. Logistic regression analysis, heatmap, and decision tree methods were used to determine predictive and prognostic factors. The study was performed retrospectively. RESULTS: Advanced age and deceased transplantation emerged as predictive of SARS-CoV-2 infection, while the presence of HLA-A*11, the HLA match ratio, and high-dose tacrolimus were identified as prognostic factors in kidney transplant recipients. HLA-A10, HLA-B*13, HLA-B22, and HLA-B*55 were shown to be associated with SARS-CoV-2 infection at univariate analysis, and HLA-B*57, HLA-DRB1*11, and HLA-DRB1*13 at logistic regression analysis. CONCLUSION: HLA-A10, HLA-B*13, HLA-B*55, HLA-B*57, HLA-DRB1*11, and HLA-DRB1*13 were identified for the first time in the literature associated with SARS-CoV-2 infection in kidney transplant recipients.

RESUMO

PURPOSE: The present study aims to develop a new high-resolution imaging system for the early diagnosis of cervical neoplasia based on increased vessel density of the cervical tissue. METHODS: An optical device was developed to obtain high contrast and resolution images of vascular structures of the cervix in the present study. The device utilizes a telecentric lens to capture cervix images under light illumination with a wavelength of 550 nm emitted from LEDs. Images were obtained using the telecentric lens with or without acetic acid application to the cervix. Image processing algorithms were used to contrast and extract the skeleton of the vascular structures on the cervix. In the evaluation of the vascular density, the cervical images were divided into 12 o'clock positions, and the fractal dimension of the vascularity was calculated for each dial area between the o'clock positions. The region with the largest fractal dimension was accepted as the region with the highest probability of lesion. The range of vessel sizes was split into small classes of "bins" for each dial area with the highest fractal dimension. To validate the system's success in differentiating between normal and HSIL lesions, forty five patients who underwent colposcopy and biopsy were included in a pilot study. RESULTS: The system correctly classified four HSIL cases out of five and failed to detect one HSIL case, achieving an accuracy rate of 97.8% with an 80% sensitivity and 100% specificity. CONCLUSION: The developed high-resolution optical imaging system may potentially be used in detecting cervical neoplasia just before the biopsy and reduce the number of false-positive cases.

RESUMO

OBJECTIVES: Changes in microbiota composition affect the aetiology and patho-genesis of chronic diseases, including Behçet's disease (BD). However, no studies have analysed the potential gut microbiota changes among different clinical forms of BD. This study evaluated the intestinal microbiota composition of patients with BD and healthy controls and also compared differences between patients with BD with respect to eye, mucocutaneous, and vascular involvement. METHODS: In this prospective cohort study, 27 patients diagnosed with BD according to the International Study Group criteria and 10 age- and sex-matched healthy controls were included. Detailed intestinal microbiota analysis was performed. RESULTS: There were no differences between the BD group and the control group in terms of alpha and beta microbial diversity and abundance indices (p>0.05). Actinomyces, Libanicoccus, Collinsella, Eggerthella, Enetrohabdus, Catenibacterium, and Enterobacter were significantly higher in the BD group than in the control group. In addition, Bacteroides, Cricetibacter, Alistipes, Lachnospira, Dielma, Akkermansia, Sutterella, Anaerofilum, Ruminococcease-UCG007, Acetanaerobacterium, and Copropaacter were lower in the BD group than in the control group. When we compared three different system involvement (eye, mucocutaneous, and vascular), the linear discriminant analysis effective size revealed a difference for the following genera: Lachnospiraceae NK4A136 in the uveitis group; Dialister, Intestinomonas, and Marvinbryantia in the mucocutaneous group; and Gemella in the vascular group. CONCLUSIONS: The composition of intestinal microbiota was significantly different in patients with BD compared with healthy adults. Ours is the first study to show differences in microbiota composition in isolated mucocutaneous, eye, and vascular involvement. These findings should be evaluated in a larger series.

RESUMO

The success of osseointegration is influenced by several factors that affect bone metabolism and by certain systemic medications. Selective serotonin reuptake inhibitors (SSRIs) have been previously suggested to be among these medications. This study aims to investigate the association between systemic intake of SSRIs and failure of osseointegration in patients rehabilitated with dental implants. A retrospective cohort study was conducted, including a total of 2055 osseointegrated dental implants in 631 patients (109 implants in 36 SSRI \users and 1946 in 595 nonusers). Predictor and outcome variables were SSRI intake and osseointegration failure, respectively. The data were analyzed with Mann-Whitney test or Fisher exact test accordingly. Both patient-level and implant-level models were implemented to evaluate the effect of SSRI exposure on the success of osseointegration of dental implants. Median duration of follow-up was 21.5 months (range = 4-56 months) for SSRI users and 23 months (range -60 months) for nonusers ( P = .158). Two of 36 SSRI users had 1 failed implant each; thus, the failure rate was 5.6%. Eleven nonusers also had 1 failed implant each; thus, the failure rate was 1.85%. The difference between the 2 groups failed to reach statistical significance at patient and implant levels ( P = .166, P = .149, respectively). The odds of implant failure were 3.123 times greater for SSRI users compared with nonusers. Patients using SSRIs were found to be 3.005 times more likely to experience early implant failure than nonusers. The results of this study suggest that SSRIs may lead to increase in the rate of osseointegration failure, although not reaching statistical significance.

RESUMO

OBJECTIVE: To examine the prevalence of comorbid conditions in patients diagnosed with fibromyalgia. METHODS: The retrospective cross-sectional study was conducted at Eskisehir Osmangazi University, Eskisehir, Turkey, and comprised data of fibromyalgia patients aged 18 years or more admitted between January 1, 2012 and August 15, 2016. Hospital's database was investigated using the International Classification of Diseases, 10th Revision codes to identify fibromyalgia cases and predetermined comorbid conditions. SPSS 21 was used for data analysis. RESULTS: Of 509 patients, 51(10%) were males and 458(90%) were females with an overall mean age of 50.24±12.32 years. Of the total, 345(67.8%) patients had at least one comorbid disease, while 164(32.2%) had no comorbid disease. The most prevalent condition was cardiovascular diseases in 187(36.7%) patients followed by endocrine diseases in 157(30.8%). CONCLUSIONS: Fibromyalgia is a disease that is seen to be increasing in frequency in recent years. It is useful to evaluate fibromyalgia patients with their comorbid conditions on their follow-up.

RESUMO

Background/aim: The optimal empiric antibiotic regimen for patients with community-acquired pneumonia (CAP) remains unclear. This study aimed to evaluate the clinical cure rate, mortality, and length of stay among patients hospitalized with community- acquired pneumonia in nonintensive care unit (ICU) wards and treated with a ß-lactam, ß-lactam and macrolide combination, or a fluoroquinolone. Materials and methods: This prospective cohort study was performed using standardized web-based database sheets from January 2009 to September 2013 in nine tertiary care hospitals in Turkey. Results: Six hundred and twenty-one consecutive patients were enrolled. A pathogen was identified in 78 (12.6%) patients. The most frequently isolated bacteria were S. pneumoniae (21.8%) and P. aeruginosa (19.2%). The clinical cure rate and length of stay were not different among patients treated with ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone. Forty-seven patients (9.2%) died during the hospitalization period. There was no difference in survival among the three treatment groups. Conclusion: In patients admitted to non-ICU hospital wards for CAP, there was no difference in clinical outcomes between ß-lactam, ß-lactam and macrolide combination, and fluoroquinolone regimens.

RESUMO

OBJECTIVES: Diabetes mellitus (DM) and hypertension (HT) are chronic disorders with which mental disorders may coexist and for which patients may resort to alternative medicine use. Alternative and complementary medicine is a treatment option that patients tend to use. This study is to determine the prevalence of mental disorders among patients diagnosed with DM and HT and their use of alternative medicine methods. Materials and Methods The study was conducted in a primary care setting. The data were collected from the Family Health Center No. 4 at Ηankaya, Ankara, Turkey. It involved patients aged between 18 and 65, who were on follow-up treatment for DM and HT. Patients accepted to participate in the study were administered the sociodemographic data form, the Primary Care Evaluation of Mental Disorders (PRIME-MD) questionnaire and the alternative medicine inquiry form. PARTICIPANTS: One hundred and sixteen patients with HT and 119 patients with DM (type 2) were recruited for the study. RESULTS: In this study, 47.4% of HT patients and 53.8% of the DM patients were diagnosed with a PRIME-MD. The most commonly encountered disorder was mood disorders, in 37.1% of the HT patients and 45.4% of the DM patients. In this study, four HT patients (0.3%) and no DM patients stated that they resorted to complimentary medicine, which can use be used alongside conventional medical treatment and may help to feel better and cope better with any chronic condition. All four HT patients were using multivitamin combinations to support the treatment. As the alternative medicine usage was described as treatment used instead of conventional medical treatment we did not find any patient using alternative medicine. CONCLUSIONS: Mental disorders may coexist with HT and DM. Some of the HT and DM patients suffering from a mental disorder seek psychiatric support, while others do not. We believe that it is important to examine patients for mental disorders, while being followed-up for a chronic disease.

RESUMO

OBJECTIVE: Neuroinflammation is the hallmark of amyotrophic lateral sclerosis (ALS) disease. Regulatory T cells (Tregs) are essential in immune tolerance and neuroinflammation prevention. It has been shown that a significant decrease in Treg and FoxP3 protein expression is observed in ALS patients. The main reason for the FoxP3+ Treg loss in ALS is unknown. In this study, the role of autophagy dysregulation in FoxP3+ Tregs in ALS was investigated. METHODS: Twenty-three ALS patients and 24 healthy controls were recruited for the study. Mononuclear cells (MNCs) were obtained from peripheral blood, and then Tregs were isolated. Isolated Tregs were stained with FoxP3 and LC3 antibodies and analyzed in flow cytometry to determine autophagy levels in FoxP3+ Tregs in patients and controls. RESULTS: The mean of FoxP3+ LC3+ cells, were 0.47 and 0.45 in patients and controls, respectively. The mean of FoxP3+ LC3- cells was 0.15 in patients and 0.20 in controls, p = 0.030 (p < 0.05). There is no significant correlation between ALSFRS-R decay rate and autophagy level in patients. Also, there is no significant difference between autophagy levels in FoxP3+ Tregs in patients with rapidly progressing ALS and slow-progressing ALS. CONCLUSION: Excessive autophagy levels in FoxP3+ Tregs in ALS patients can potentially be an explanation for an increased cell death and result in worsened neuroinflammation and disease onset. However, the disease progress is not attributable to autophagy levels in FoxP3+ Tregs.

RESUMO

OBJECTIVES: Artificial intelligence-based robotic systems are increasingly used in medical laboratories. This study aimed to test the performance of KANKA (Labenko), a stand-alone, artificial intelligence-based robot that performs sorting and preanalytical quality control of blood tubes. METHODS: KANKA is designed to perform preanalytical quality control with respect to error control and preanalytical sorting of blood tubes. To detect sorting errors and preanalytical inappropriateness within the routine work of the laboratory, a total of 1000 blood tubes were presented to the KANKA robot in 7 scenarios. These scenarios encompassed various days and runs, with 5 repetitions each, resulting in a total of 5000 instances of sorting and detection of preanalytical errors. As the gold standard, 2 experts working in the same laboratory identified and recorded the correct sorting and preanalytical errors. The success rate of KANKA was calculated for both the accurate tubes and those tubes with inappropriate identification. RESULTS: KANKA achieved an overall accuracy rate of 99.98% and 100% in detecting tubes with preanalytical errors. It was found that KANKA can perform the control and sorting of 311 blood tubes per hour in terms of preanalytical errors. CONCLUSIONS: KANKA categorizes and records problem-free tubes according to laboratory subunits while identifying and classifying tubes with preanalytical inappropriateness into the correct error sections. As a blood acceptance and tube sorting system, KANKA has the potential to save labor and enhance the quality of the preanalytical process.

RESUMO

PURPOSE: Autotitrating continuous positive airway pressure (auto-CPAP) devices not only titrate CPAP pressures but also measure residual respiratory events. The aim of the present study was to determine the accuracy of auto-CPAP-derived residual apnea-hypopnea index (AHI). METHODS: We studied 137 consecutive patients (72.3% men) with obstructive sleep apnea from January 2008 to December 2010 who underwent in-laboratory overnight polysomnography (PSG) using auto-CPAP. We excluded patients with comorbidities like congestive heart disease, chronic obstructive pulmonary disease, or hypoventilation syndromes and patients with central sleep apnea. Residual AHI obtained from the auto-CPAP device by smart card (CPAP-AHI) was compared simultaneously with AHI from an overnight PSG on auto-CPAP (PSG-AHI) using Bland-Altman analysis and Wilcoxon signed-rank test. RESULTS: The mean AHI on the diagnostic study was 45.08 ± 1.8. During the titration, auto-CPAP markedly suppressed the respiratory events (PSG-AHI, 3.40 ± 0.20). On the other hand, CPAP-AHI was 3.35 ± 0.17. Bland-Altman analysis showed good agreement between auto-CPAP-AHI and PSG-AHI (AHI mean difference of 0.05, and the limits of agreement for the AHI were from +4.9 to -4.8). Two methods have also been compared with paired samples t test and no statistically significant difference was found (p > 0.05). CONCLUSION: Auto-CPAP can identify residual respiratory events equivalent to the use of PSG in a selected population.

RESUMO

OBJECTIVE: The main goal of chronic kidney disease (CKD) treatment is the prevention of progression of the disease and complications. Inappropriate drug use in patients with CKD is an important issue, which may cause adverse effects on patients and progression of chronic renal failure. The aim of this study is to find the rate of inappropriate drug use among CKD patients. METHODS: The subjects of this study were selected from the patients with a CKD history of minimum one year, who did not receive renal replacement therapy. Patients were asked to provide a digital record of the drugs they used over the last one year. Individually, for each patient, the drugs that may be contraindicative and that require dose adjustment were identified based on glomerular filtration rate (GFR). RESULTS: This study includes a total of 185 participants - 97 female (52.4%) and 88 male (47.6%) patients. The average age of patients was 60.50 ± 14.56. It was shown that 149 patients (80.5%) were using inappropriate drugs. Seventy (47.0%) were using one, 79 (53.0%) two, 30 (20/1%) three, and 9 (6.4%) four inappropriate drugs. Of CKD patients, 44.3% were aged 65 or over; and in this age group, inappropriate drug use was more frequent compared to the population below 65 (86.6% vs. 75.7%). The drugs used inappropriately were, respectively, nonsteroidal anti-inflammatory drugs (65.8%), quinolone antibiotics (39.0%), ACE inhibitors (26.9%). DISCUSSION: Health professionals are required to consider renal functions of all patients, mainly those aged over 65, when administering a treatment.

RESUMO

AIM: Our aim was to detect older patients who were prescribed inappropriate drugs according to START/STOPP criteria in primary care. MATERIALS AND METHOD: Patients aged over 65, admitted to health center no. 5 in Afyon, were included. The files of the subjects were surveyed retrospectively for the final one year in the digital environment, using the Family Medicine Information System. The files surveyed allowed us to list the drugs they used in the past year and to detect inappropriate drug use. RESULTS: The number of patients that took part in this study was 325 (average age: 73.23 ± 6.44 years). We found that, among these participants, 48 patients (14.8%) were using drugs inappropriately according to STOPP criteria. CONCLUSION: Further focus on avoiding inappropriate drug use will allow clinicians and other health professionals to reduce side effects and other complications. In patients aged over 65, there is a need to attach particular importance to inappropriate drug use, drug interactions, and avoidance of side effects.

RESUMO

PURPOSE: This study aimed to conduct a large-scale population-based study to understand the epidemiological characteristics of Primary Malignant Bone Tumors (PMBTs) and determine the prognostic factors by concurrently using the classical statistical method and data mining methods. METHODS: Patients included in this study were extracted from the National Cancer Institute's Surveillance, Epidemiology and End Results (SEER) database: "Incidence-SEER Research Data, 18 Registries, Nov 2020 Sub". Patients with unclassified and incomplete information were excluded. This search algorithm resulted in a dataset comprising 6234 cases. Survival analyses were performed with Kaplan-Meier curves and the Log-rank test. Multivariate Cox regression analysis determined the independent prognostic factors of PMBT. A decision tree-based data mining technique was used in this study to confirm the prognostic factors. RESULTS: 5-years survival rate was 63.6% and 10-years survival rate was 55.3% in the patients with PMBT. Sex, age, median household income, histology, primary site, grade, stage, metastasis, and the total number of malignant tumors were determined as independent risk factors associated with overall survival (OS) in the multivariate COX regression analysis. The prognostic factors resulting in five terminal nodes in the decision tree (DT) included stage, age, and grade. The stage was the most important determining factor for vital status. The terminal node with the shortest number of surviving patients included 801 (72.3%) deaths in 1102 patients with distant stage, and hazard ratio was calculated as 5.4 (95% CI: 4.9-5.9; p < .001). These patients had a median survival of only 17 months. CONCLUSIONS: Rules extracted from DTs provide information about risk factors in specific patient groups and can be used by clinicians making decisions on individual patients. We recommend using DTs in combination with COX regression analysis to determine risk factors and the effect of these factors on survival.

RESUMO

Objective: The study aims to analyze the quality of studies that make economic evaluations for amyotrophic lateral sclerosis (ALS). Assessing the quality of studies can guide policy-making and planning. Methods: One of the most recognized checklists "The Consensus on Health Economic Criteria" (CHEC)-list designed by Evers et al. in 2005 aims to answer two important questions: is the methodology of the study appropriate, and are the results of the study valid? We reviewed studies focusing on ALS and its economic costs, and evaluated the studies with (CHEC)-list. Results: We examined 25 articles in terms of their cost evaluation and quality. It is seen that they mainly focus on medical costs, ignoring social care costs. When the quality of the studies is examined, it is seen that the studies overall achieve high scores in terms of their purpose and research question, but some of the studies score low in terms of ethical dimension, comprehensiveness of expenditure items, their application of sensitivity analyses and their study design. Conclusions: The main recommendation of our study for future cost evaluation studies is that they should focus on the questions in the checklist that are scored low overall by the 25 articles, and consider the social care costs as well as medical costs. Our recommendations when designing cost studies can be applied to other chronic diseases with long-term economic costs like ALS.

RESUMO

Cervical cancer presents a significant global health concern with high-risk human papillomaviruses (HPVs) identified as the main cause of this cancer. Although current treatment methods for cervical cancer can eliminate lesions, preventing metastatic spread and minimizing tissue damage remain a major challenge. Therefore, the development of a safer and innovative therapeutic approach is of the utmost importance. Natural products like fig latex, derived from the Ficus carica tree, have demonstrated promising anti-cancer properties when tested on cervical cancer cell lines. However, the specific mechanisms by which fig latex exerts its effects are still unknown. In this study, we conducted RNA-Seq analysis to explore how fig latex may counteract carcinogenesis in HPV-positive cervical cancer cell lines, namely, CaSki (HPV type 16-positive) and HeLa (HPV type 18-positive). Our results from this investigation indicate that fig latex influences the expression of genes associated with the development and progression of cervical cancer, including pathways related to "Nonsense-Mediated Decay (NMD)", "Cell Cycle regulation", "Transcriptional Regulation by TP53", and "Apoptotic Process". This selective impact of fig latex on cancer-related pathways suggests a potential novel therapeutic approach for HPV-related cervical cancer.

RESUMO

BACKGROUND: Predicting the long-term disability outcomes of multiple sclerosis (MS) cases is challenging. OBJECTIVE: We prospectively analysed our previous MS cohort with initial cerebrospinal fluid (CSF) proteomics data to reveal disability markers after 8.2±2.2 years of follow-up. METHODS: Patients with regular follow-up visits were assigned into two groups: those with an age-related MS severity (ARMSS) score ≥5 (unfavourable course group, N = 27) and ARMSS score <5 (favourable course group, N = 67). A machine learning-based algorithm was applied to reveal candidate poor prognosis-associated initial CSF proteins, which were measured in an independent MS cohort (verification group, N = 40) by ELISA. Additionally, the correlation of initial clinical and radiological parameters with long-term disability was analysed. RESULTS: CSF alpha-2-macroglobulin (P = 0.0015), apo-A1 (P = 0.0016), and haptoglobin (P = 0.0003) protein levels, as well as cerebral lesion load (>9 lesions) on magnetic resonance imaging, gait disturbance (P = 0.04), and bladder/bowel symptoms (P = 0.01) were significantly higher in the unfavourable course group than in the favourable course group. Optic nerve involvement evident on initial magnetic resonance imaging (P = 0.002) and optic neuritis (P = 0.01) were more frequent in the favourable course group. CONCLUSION: The herein identified initial CSF protein levels, in addition to the clinical and radiological parameters at disease onset, have predictive value for long-term disability in MS cases.
