Abstract
Objective To characterize the eosinophilic granulomatosis with polyangiitis (EGPA) population from the POLVAS registry depending on ANCA status and diagnosis onset, including their comparison with the granulomatosis with polyangiitis (GPA) subset with elevated blood eosinophilia (min. 400/μl) (GPA HE) to develop a differentiating strategy. Methods A retrospective analysis of the POLVAS registry. Results The EGPA group comprised 111 patients. The ANCA-positive subset (n = 45 [40.54%]) did not differ from the ANCA-negative one in clinics. Nevertheless, cardiovascular manifestations were more common in ANCA-negative patients than in those with anti-myeloperoxidase (MPO) antibodies (46.97% vs. 26.92%, p = 0.045). Patients diagnosed before 2012 (n = 70 [63.06%]) were younger (median 41 vs. 49 years, p < 0.01), had higher blood eosinophilia at diagnosis (median 4,946 vs. 3,200/μl, p < 0.01), and more often ear/nose/throat (ENT) and cardiovascular involvement. GPA HE comprised 42 (13.00%) out of 323 GPA cases with reported blood eosinophil count. Both GPA subsets had a lower prevalence of respiratory, cardiovascular, and neurologic manifestations but more often renal and ocular involvement than EGPA. EGPA also had cutaneous and gastrointestinal signs more often than GPA with normal blood eosinophilia (GPA NE) but not GPA HE. The model differentiating EGPA from GPA HE, using ANCA status and clinical manifestations, had an AUC of 0.92, sensitivity of 96%, and specificity of 95%. Conclusion Cardiovascular symptoms were more prevalent in the ANCA-negative subset than in the MPO-ANCA-positive one. Since EGPA and GPE HE share similarities in clinics, diagnostic misleading may result in an inappropriate therapeutic approach. Further studies are needed to optimize their differentiation and tailored therapy, including biologics.

Abstract
BACKGROUND The increase in intraocular pressure during hemodialysis challenges nephrologists and ophthalmologists. It most often affects patients with previously diagnosed glaucoma and is particularly dangerous in the setting of diabetic retinopathy. Hypoperfusion and hypoxia of the retina may occur, leading to pathologic neovascularization in the retina and the anterior chamber angle. Changes in the filtration angle block the outflow of aqueous humor and cause secondary glaucoma. A special type of glaucoma is neovascular glaucoma, developing among others in patients with diabetic retinopathy. This study describes a patient with secondary neovascular glaucoma in whom a significant increase in intraocular pressure was observed during hemodialysis, not responding to the applied topical treatment. METHODS The patient experienced severe pain, and her cornea was constantly injured by paracentesis. Ultimately, secondary glaucoma led to a significant decrease in vision in both eyes. The patient was enrolled on a transplant waiting list and transplanted with priority. RESULTS The patient experienced some urologic and infectious complications, although 7 months after transplantation, her creatinine concentration was 1.2 mg/dL, and the ocular disease was stabilized. The intraocular pressure decreased, but there were still values above the norm, which required periodic injections of anti-vascular endothelial growth factor into the vitreous chamber and 5-fluorouracil injections under the conjunctiva. CONCLUSIONS Patients with diabetes and secondary neovascular glaucoma on dialysis constitute an extremely difficult therapeutic problem and require the involvement of several specialists. Successful kidney transplantation, besides ameliorating general clinical conditions, may increase the chance of successful ophthalmologic treatment.

Abstract
BACKGROUND The diagnosis of tuberculosis (TB) in solid organ transplant (SOT) recipients presents challenges that may lead to treatment delay. These include atypical clinical presentations, increased likelihood of negative tuberculin skin test or/and interferon-gamma release assays, and negative sputum smear results despite active disease. The treatment poses challenges due to pharmacokinetic interactions, allograft-related toxicity, and inadequate immune response. CASE REPORT We report the case of a 70-year-old man after kidney transplantation in 2012. The patient was transferred from the urology unit with deteriorating renal function and presumed urosepsis. His pulmonary chest X-ray showed hilar pulmonary infiltrates. Computed tomography of the chest/abdomen/pelvis revealed mediastinal lymphadenopathy, pulmonary infiltrates, pulmonary effusion, and splenomegaly. His blood results showed pancytopenia and high inflammatory and renal markers. He was treated with broad-spectrum antibiotics covering bacterial, fungal, and viral infections. Despite initial clinical improvement, his kidney function deteriorated, and he required hemodialysis. His temperature continued to spike. On physical examination, he was confused and lethargic. He was scheduled to have a mediastinoscopy with lymph node biopsy, but he died the day before. The postmortem examination revealed miliary tuberculosis with tuberculosis of many organs: kidney transplant, native kidney, bone marrow, mediastinal lymph nodes, lungs, and spleen. CONCLUSIONS The diagnosis of active TB in transplant recipients requires a high index of suspicion and invasive procedures. The majority of all cases of active TB after SOT are disseminated or occur at extrapulmonary sites. Only a small minority of patients have classic cavitary changes on pulmonary imaging.

Abstract
The damage to small vessels in AAV and inflammatory reactions are accompanied by the release of various chemokines and cytokines. Using a flow cytometry technique, we assessed the levels of specific cytokines, namely IL-1β IL-6, IL-8, IL-10, IL12p70, and TNF, and chemokines, IFN-α, IP-10, and MIG in the serum from 9 healthy volunteers and 20 AAV patients, where 11 of the patients were not treated and evaluated at the time of diagnosis and 9 were already diagnosed and taking CY + GCS. The obtained results were then compared considering the activity of the disease, the type and titre of the ANCA antibodies, the inflammatory status, and the kidneys' condition. Amongst others, the IL-6, IL-8, IL-10, TNF, and MIG levels were much higher in the serum of AAV patients than in healthy controls, whereas the level of IL-1β was higher in healthy volunteers. Additionally, the levels of IL-6, IL-10, IP-10, and MIG negatively correlated with the eGFR level, while the level of IFN-α positively correlated with the titre of PR3-ANCA. As most of the molecules are implicated in trafficking primed neutrophils towards small vessels, looking for links between the levels of these cytokines/chemokines and the clinical symptoms of AAV may facilitate the diagnosis and predict the progression of the disease.

Abstract
It has been hypothesized that α-Klotho deficiency might contribute to chronic inflammation in patients with end-stage renal disease (ESRD), especially those on hemodialysis (HD). Serum Klotho levels by some authors are considered a potential predictor of cerebrovascular events. Therefore, we analyzed serum levels of α-Klotho with ELISA and inflammation-related cytokines in HD patients. Sixty-seven HD patients and 19 healthy people were recruited between November 2017 and June 2021. A Cytometric Bead Array (CBA) was used to determine the level of different cytokines: IL-12p70, TNF, IL-10, IL-6, IL-1β, and IL-8. A human Klotho ELISA kit was used to determine the level of α-Klotho in the plasma samples of HD patients. There was no difference in serum levels of α-Klotho between HD patients and healthy people. Patients had increased serum IL-6 and IL-8. Significant positive correlations existed between the concentration of α-Klotho and the serum concentrations of IL-12p70, IL-10, and IL-1β. However, in a multivariable linear regression analysis, only patients' age was associated independently with α-Klotho level. Serum α-Klotho was not associated with higher mortality risk in HD patients. While these results draw attention to potential relationships between α-Klotho proteins and inflammatory markers in HD patients, our cross-sectional study could not confirm the pathogenic link between α-Klotho, inflammation, and cardiovascular mortality.

Abstract
BackgroundANCA associated vasculitides (AAV) are a heterogeneous group of rare diseases with unknown etiology. In the most severe cases AAV can lead to end stage kidney disease or death. Since etiology and detailed pathogenesis of AAV is not known, the prediction of disease outcome at the time of diagnosis is challenging. Thus, there is an unmet need for tools to identify patients with the highest risk of organ dysfunction and death and apply effective personalized therapy.ObjectivesThe aim of this work was to search for tools allowing outcome prediction at the time of AAV diagnosis. Early identification of patients, who are likely to develop severe organ dysfunction and death is crucial for appropriate disease management. Induction therapy in AAV relays on immunosuppressive drugs characterized by a high risk of severe side effects. Thus, their administration in high doses should be limited only to individual patients with an especially high risk of poor outcome.MethodsWe applied here two methods of identification of AAV patients at risk to develop severe organ dysfunction and death. First method (latent class analysis [LCA] followed by logistic regression) was meant to subcategorize patients and identify a subgroup at subjects at risk to develop chronic renal replacement therapy (CRRT) and death [1]. Second, served to assess individual poor outcome risk and was based on two machine learning (ML) classifiers, which by analyzing clinical information allow assigning computed risk for CRRT and death in an individual patient allowing to identify subjects with high risk of chronic replacement therapy (CRRT) and death. We have evaluated a number of different approaches to build the ML models (including logistic regression, support vector machines, random forests), and obtained the best results for the gradient boosting algorithm implementation called LightGBM [2]. It works as a sequential ensemble of so-called weak learners (decision trees) finally combined in a one prediction model. Both analyses were based on retrospective data from Polish national AAV registry (POLVAS) [3] including presently 565 GPA and 135 MPA patients. The parameters used were: demographic data and laboratory parameters, specific organ involvement, ANCA specificity and time between selected stages of the disease.ResultsLCA used on our AAV cohort identified four subphenotypes – three already previously proposed - and revealing a fourth clinically relevant subphenotype. This new subphenotype includes only GPA patients, usually diagnosed at a younger age as compared to other groups, and characterized by multiorgan involvement, high relapse rate, relatively high risk of death, but no end-stage kidney disease. Logistic regression analysis revealed significant differences in the risk of CRRT and death between those subphenotypes – the worst prognosis was found for severe MPO AAV. On the other hand, using ML approach we obtained an individual prediction model with potentially relevant clinical performance (ROC AUC of 0.85 for CRRT and 0.82 for death).ConclusionWe consider results obtained encouraging. They may offer a new insight into AAV course based on data available at diagnosis, and create a solid foundation for potential clinical decision support system.References[1]Wójcik K et al.

Abstract
INTRODUCTION Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is characterized by the presence of proteinase‑3 (PR3) or myeloperoxidase (MPO) ANCA. In over 90% of cases, PR3‑ANCA is associated with granulomatosis with polyangiitis (GPA). However, it is also rarely found in microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangiitis (EGPA). On the other hand, MPO‑ANCA being characteristic of MPA (>90% of cases), is also found in about 40% of EGPA and 5% of GPA patients. On the ground of this overlap, clinical importance of ANCA specificity identification has been questioned. OBJECTIVES In this study, we analyzed the clinical and demographic characteristics of AAV subgroups identified by ANCA serotype. PATIENTS AND METHODS We conducted a multicenter study of AAV patients (417 GPA, 106 MPA, 102 EGPA; diagnosed between 1990 and 2016), included in the POLVAS registry. The data were systematically collected according to a standardized protocol. RESULTS In the ANCA-positive group (anti‑MPO, anti‑PR3) a male-to-female ratio was 1:1, whereas in the ANCA-negative group it was 1:2, regardless of AAV diagnosis. Anti‑MPO antibodies were present in significantly older patients. Patients with MPO+GPA and MPO+EGPA were older than those with corresponding ANCA‑negative GPA and EGPA as well as PR3+AAV. Moreover, ANCA‑negative AAV was characterized by a low risk of end‑stage kidney disease and death. CONCLUSIONS The presence and specificity of ANCA in AAV patients are related to sex and age, determine their organ involvement and influence mortality as previously shown. Patients with MPO‑ANCA-positive AAV constitute a clinically homogeneous group, whereas PR3‑ANCA-positive patients are much more clinically heterogeneous. ANCA-negative AAV patients are characterized by better prognosis. Thus, ANCA identification is an indispensable element and should not be omitted in establishing AAV diagnosis.

Abstract
HD patients have impaired adaptive immune responses, which might depend on the primary cause of chronic kidney disease (CKD). We analyzed percentages of T cells subpopulations with the expression of CD69, CD25, CD95, and HLA-DR antigens in HD patients to determine the status of T cell activation. Also, we determined serum levels of cytokines: IL12p70, TNF, IL-10, IL-6, IL-1β, IL-8. HD patients had increased percentages of CD4+CD25+, CD4+CD69+, CD4+HLA-DR+, CD8+CD69+, and CD8+HLA-DR+ cells compared to healthy people. Also, their IL-6 and IL-8 serum levels were higher. Changes in T cell subpopulations were seen in patients with diabetic nephropathy (DN) or ischemic nephropathy (IN) but not with glomerulonephritis (GN). HD patients dialyzed for more than six months had a lower percentage of CD4+CD69+, CD8+HLA-DR+, CD8+CD95+ cells, higher IL-12p70 levels, and lower IL-8 levels. Our results show that HD treatment and CKD cause influence T cell activation status.

Abstract
The levels of thiamine diphosphate (ThDP), the most active biologically form of vitamin B1, were assessed in whole blood oflong-term haemodialysed patients (n = 50), by applying chromatographic methods based on RP-HPLC technique with isocratic elution and fluorescence detection. The target analyte, thiochrome diphosphate (ThODP), was obtained by pre-column derivatization of vitamin B1 contained in blood samples, applying deproteination with trichloroacetic acid, following by oxidation with alkaline solution of potassium ferricyanide(III) and stabilization with DTT before assays. A simple and sensitive assay was developed, and the results were referenced to the commercially available test. Steady-state and time-resolved studies on emissive properties of ThODP enabled optimization of the proposed assay. The F-Snedecor test shown no statistically significant differences between both approaches. Assessed parameters of the proposed assay, such as linearity, precision, sensitivity, and recovery, were satisfactory if compared to the reference one. The LOQ value for ThDP in whole blood of studied group of patients was of 0.5 ng/mL and the recovery of88%. The results disclosed high individual variabilities in the interdialytic deficiencies of ThDP among the patients - ranged from afew percent to values close to 100%. A comprehensive clinical data, characterizing patients under study, were processed together, and analysed by employing achemometric discriminative tool, the Principal Components Analysis,to find interdependences among clinical data characterizing patients. The three Principal Components were disclosed, that in sum explained almost 50% of the observed variability of the clinical data set. Among the clinical parameters involved in PCs were dialyzer membrane and type, duration as well as levels of creatinine, haemoglobin, and red blood cells in patients' whole blood.

Abstract
Background:ANCA associated vasculitides (AAV) are a heterogeneous group of rare diseases with unknown etiology and the broad clinical spectrum ranging from life-threatening systemic disease, through single organ involvement to minor isolated skin changes. Unfortunately the clinical classification, ANCA specificity or genetic characteristics alone is not able to categorize AAV patients in a satisfactory manner. As a consequence advanced statistical techniques were used to identify and stratify AAV subphenotypes [1, 2]. Here we have analyzed influence of the ANCA type on clinical manifestations and demographic characteristics in various types of AAV, based on data from the POLVAS registryObjectives:We decided to retrospectively analyze a large cohort of Polish AAV patients deriving from several referral centers – members of the Scientific Consortium of the Polish Vasculitis Registry (POLVAS) – and concentrate on demographic and clinical characteristics of anti-PR3 and anti-MPO positive patients regardless of their clinical diagnosis.Methods:We conducted a systematic multicenter retrospective study of adult patients diagnosed with AAV between Jan 1990 and Dec 2016. Patients were enrolled by 9 referral centers. We analyzed dichotomous variables: gender; ANCA status – anti-PR3+ or anti-MPO+, ANCA negative; organ involvement - skin, eye, ENT, respiratory, heart, GI, renal, urinary, CNS, peripheral nerves and polytomous variable (number of relapses), supported by quantitative covariates (e.g., age at diagnosis, CRP at diagnosis, maximal serum creatinine concentration ever)[3].Results:MPO-positive patients (both GPA and EGPA phenotype) were older at the time of diagnosis with a substantial percentage diagnosed > 65 years of age, and with high rate of renal involvement. Interestingly, while in the whole group of patients diagnosed with EGPA male to female ratio was 1:2, the MPO+ EGPA patients showed M:F ratio of 1:1.The analysis of ANCA negative AAV reveled significant differences in GPA, ANCA negative group is characterized with significantly lower frequency of renal involvement compared to rest GPA (11,5% vs 63,7%) p<0,05 what should be emphasized ANCA negative AAV never lead to ESRD (end stage renal disease) or even transient dialysis.Conclusion:ANCA specificity is indispensable as a separate variable in any clinically relevant analysis of AAV subcategories. MPO+ group is characterized by older age at time of diagnosis, male to female ration 1:1, kidney involvement, and shows more homogenous clinical phenotype than PR3+ AAV patients. In our group ANCA negative AAV never lead to ESRD (end stage renal disease) or even transient dialysis.References:[1]Mahr A, Specks U, Jayne D.

Abstract
Background:Rituximab (RTX) is a B cell depleting monoclonal antibody with proven efficacy in the treatment of ANCA-associated vasculitis (AAV). The infectious complications occur in 15-25%.Objectives:We aimed to assess the frequency and risk factors of infections in patients with AAV receiving RTX among Polish patients.Methods:7 tertiary referral centers experienced in the treatment of vasculitis completed a questionnaire regarding AAV patients treated with RTX.Results:Among 49 patients included in the analysis (47 with GPA, 2 with MPA; 36/73% men; mean age at diagnosis 42,45±14,9 yrs., mean age on RTX initiation 46,14±14,72 yrs.,) at least one infection occurred in 20 patients (40.82%) after mean time of 16,65±16,01 weeks since the administration of RTX. Patients were followed for a mean time of 26,88±21,94 months. There were no differences in the incidence of infectious complications by gender, age, BMI, smoking status, severity of the disease, activity of the disease (BVAS), time from diagnosis to RTX initiation, carriage of staphylococcus aureus in the upper respiratory tract, total dose of CYC before RTX treatment. We didn’t observe severe hypogammaglobulinemia or neutropenia after RTX treatment. 40% of the observed infections occurred during the first month, 35% between second and sixth month of follow-up, while 25% were observed between 6 and 12 months after the RTX initiation. Of the 20 patients who developed infection, 12 (24.5%) had further infections. Antibiotic prophylaxis with trimethoprim–sulfamethoxazole was administered in 40 out of 49 (81.63%). Upper respiratory tract infection was the most common infectious complication (n=11), followed by lower respiratory tract (n=4), soft tissues (n=4) and urinary tract infections (n=4), lacrimal gland abscess (n=2) and abdomen (n=1). In cases with a positive microbial result Staphylococcus aureus (n=4), Klebsiella pneumoniae (n=2), Pseudomonas aeruginosa (n=1), Candida (n=1) and others (n=6) were identified. No fatalities were recorded and only 3 patients had severe infection with the necessity of prolonged treatment.Conclusion:Despite the high number of infections in our group treated with RTX, most of them were not severe. Upper respiratory tract was the most common site of infection.Disclosure of Interests:None declared

Abstract
Background:ANCA associated vasculitides (AAV) are a heterogeneous group of rare diseases with unknown etiology and the clinical spectrum ranging from life-threatening systemic disease, through single organ involvement to minor isolated skin changes. Thus there is an unmet need for phenotype identification especially among patients with granulomatosis with polyangiitis GPA, patients with microscopic polyangiitis MPA group seems to be more uniform. Recently, based on previous clustering analysis and clinical, histopathological, serological and prognostic aspects three subcategories of AAV have been proposed and named as: non-severe AAV, severe PR3-AAV and severe MPO-AAV [1].Objectives:In line with these attempts to subcategorize AAV we decided to use latent class analysis (LCA) on a large multicenter cohort of polish AAV patients from POLVAS [2] registry to identify potential new subphenotypes or confirm already proposed ones.Methods:Latent Class Analysis (LCA) approach was used as a model based clustering method of objects described by dichotomous (e.g., gender; ANCA status – cANCA, pANCA; organ involvement - skin, eye, ENT, respiratory, heart, GI, renal, urinary, CNS, peripheral nerves) and polytomous (number of relapses) variables supported by quantitative covariates (e.g., age at diagnosis, CRP at diagnosis, maximal serum creatinine concentration ever).Results:Results of LCA on our AAV group returned four class model of AAV subphenotypes, confirming existence of the previously proposed by Mahr at al. [1] and revealed fourth – previously not described clinically relevant subphenotype. To this fourth class - belong patients only with GPA, diagnosed at young age, with multiorgan involvement, high relapse rate and relatively high risk of death.Table 1.AAV subcategorization – summary of clinical characteristics and ANCA specificityLCA Class 1LCA Class 2LCA Class 3LCA Class 4No of patients13019410297AAV typeMainly GPAMainly GPAmainly MPAOnly GPAAge at diagnosisMiddle ageMiddle ageOldYoungMale/female ratio1:22:11:11:1Main organ involvementENT, respiratory, eyeRenal, respiratory, ENTRenal, respiratory, skinMultiorgan involvementRelapse rateintermediateintermediatelowhighModified class description (based on ref.

Abstract
Background:Orbital inflammatory masses have been described as the common manifestation of granulomatosis with polyangiitis (GPA) occuring in 7- 45% of patients.Objectives:Identification and characterization of patients with orbital pseudotumor among Polish patients based on the national vasculitis registry, POLVAS.Methods:Clinical presentation and management of all GPA patients fulfilling ACR criteria or Chapel Hill Consensus Conference definition included to the Polish registry POLVAS who developed orbital masses in the course of GPA were evaluated.Results:Ocular involvement was found in 114 (27%) of 417 GPA patients registered in POLVAS, 34 (8%) developed orbital masses. Mean patients’ age was 47.8 (range from 19-75) yrs., 23 (67%) were women. Forty four per cent of the patients developed tumor at the beginning of the disease, 56% during relapse. Patients’ characteristics on diagnosis of orbital mass: 24 cANCA, 2 pANCA, and 8 ANCA negative, 9% active smokers and 31% past smokers, 29% had localized disease, 21% early systemic and 50% systemic with organ involvement, 29% had other type of ophthalmological involvement before pseudotumor occurred, 88% had active paranasal sinus involvement, 41% lungs, 15% CNS, 15% skin and 6% heart manifestations. Thirty seven per cent of patients had positive nasal swabs cultures, 50% of which were positive for Staphylococcus aureus. In 65%, tumor occurred during steroid therapy (46% had prednisone more than 5mg/d) and 45% on immunosuppressive treatment (19% when treated with AZA, 16% MTX, 6,5% MMF and 3,5% CYC). Due to orbital mass 86.5% were treated with CYC and 13.5% with RTX. Twenty one per cent had complete remission of the pseudotumor, 76% partial remission and in 3% patients there was no response to the treatment; 43% developed visual impairment, 20% suffered from blindness.Conclusion:Orbital inflammatory mass was not common manifestation of GPA among our patients. The mass developed at the beginning or in the course of the disease, even during immunosuppressive treatment. Orbital masses have been resistant to therapeutic interventions and were accompanied by high risk of visual impairment.Disclosure of Interests:Anna Masiak: None declared, Marcin Ziętkiewicz: None declared, Krzysztof Wójcik: None declared, Katarzyna Wawrzycka-Adamczyk: None declared, Radoslaw Jeleniewicz: None declared, Marta Madej: None declared, Joanna Kur-Zalewska: None declared, Katarzyna Jakuszko: None declared, Małgorzata Wisłowska: None declared, Hanna Storoniak: None declared, Michał Komorniczak: None declared, Barbara Bułło-Piontecka: None declared, Iwona Brzosko: None declared, Małgorzata Stasiek: None declared, Eugeniusz Kucharz: None declared, Alicja Dębska-Ślizień: None declared, Maria Majdan Consultant of: Roche, Amgen, Speakers bureau: Roche, Amgen, Jacek Musiał: None declared, Zbigniew Zdrojewski: None declared

Abstract
Aim: (1) To describe the whole blood content of thiamine diphosphate (TDP), a biologically active form of vitamin B1 in end-stage kidney disease patients treated with hemodialysis (HD); (2) to establish the impact of a single HD procedure on TDP blood concentrations; and (3) to describe potential explanatory variables influencing TDP dialysis related losses, including dialysis prescription, vitamin B1 dietary intake and supplementation. Methods: Single-center, cross-sectional study in 50 clinically stable maintenance HD patients. The assessment of whole blood TDP with the High Performance Liquid Chromatography method, before and after a single, middle-week dialysis session and analysis of clinical and laboratory parameters potentially influencing TDP status Results: We report a significant difference in TDP levels before and after HD sessions - 42.5 (95% CI 38.7-46.2) μg/L and 23.6 (95% CI 18.9-28.2) μg/L, respectively (p = 0.000). The magnitude of intradialytic TDP changes is highly variable among individuals and is negatively associated only with the body weight of the patients (p < 0.013). Vitamin B1 dietary intake and supplementation do not influence whole blood TDP and dialysis-related loss of TDP. Conclusions: TDP, a bioactive compound of vitamin B1, is substantially lost during the HD procedure, and the magnitude of its loss is associated with the patient's body weight but it is not influenced by vitamin B1 dietary intake and standard supplementation dose.
