Renal and patient outcomes of emergency hemodialysis in elderly individuals: a retrospective cohort study.

PURPOSE: The aging population, commonly defined as individuals aged 65 and above, faces an increased risk of kidney-related diseases. This study investigates emergency dialysis in the elderly population, focusing on indications, clinical and laboratory findings, renal status, and mortality rates. METHODS: The data of 442 elderly patients (≥ 65 years old) who underwent emergency dialysis at a tertiary university hospital were retrospectively examined. Demographics, comorbidities, emergency dialysis indications, clinical presentation, method, complications, pre/post-dialysis status, and follow-up were assessed. RESULTS: 74.9% of the patients had a history of chronic kidney disease (CKD). Emergency dialysis was mainly initiated due to hypervolemia (43.7%) and uremic symptoms (29.2%). Hypotension was the most common dialysis-related complication (34.4%). The mortality rate was 34.6%; among the survivors, 15.2% achieved complete renal recovery, while 32.5% and 52.3% developed dialysis-independent and -dependent CKD, respectively. In multivariate analysis, blood urea, serum sodium, mean arterial pressure, dyspnea, tachypnea, and tachycardia on admission were found to be associated with mortality. CONCLUSION: Our study provides insights into emergency dialysis challenges in the elderly population, emphasizing the need for personalized interventions and further research to improve care and outcomes in this growing demographic.

Anakinra in idiopathic recurrent pericarditis: a comprehensive case series and literature review.

OBJECTIVE: Idiopathic recurrent pericarditis (IRP) is defined by recurring episodes of pericardial inflammation without a known cause. This study investigates the safety and efficacy of anakinra, an interleukin­1 inhibitor, as a successful therapy for IRP in cases resistant to conventional treatment. METHODS: A retrospective evaluation of patients treated at our autoinflammatory center between 2011 and 2023 was conducted. Patient files were examined for demographic, clinical, and treatment response data, including nonsteroid anti-inflammatory drugs (NSAIDs), corticosteroids, and colchicine. Monogenic autoinflammatory disease screening was performed for Mediterranean Fever (MEFV), tumor necrosis factor receptor-associated periodic syndrome (TRAPS), mevalonate kinase (MVK), nucleotide-binding domain, leucine-rich-containing family, pyrin domain-containing-3 (NLRP3), and nucleotide-binding oligomerization domain-containing protein 2 (NOD2). Patients who experienced multiple episodes of pericarditis were diagnosed with recurrent pericarditis. The study evaluated anakinra treatment in IRP patients unresponsive to conventional therapy. RESULTS: The study included 21 participants, 9 (42.9%) female and 12 (57.1%) male. The average age of the participants was 43.1 ± 16.5 years. The MEFV mutation analysis revealed that 2 (9.5%) had a mutation in exon 10 and 4 (19.0%) had one in exon 2. Out of the 16 cases, 15 successfully discontinued steroid treatment. Four patients (19.0%) experienced injection site reactions. C­reactive protein (CRP) levels were measured at an average of 196 ± 67.8 mg/l before and 2.6 ± 3.15 mg/l after anakinra treatment. CONCLUSION: In conclusion, the study adds to the growing evidence for the efficacy of interleukin-1 inhibitors, such as anakinra, as a promising treatment modality for IRP in cases resistant to conventional treatment.

Renal Manifestations in Inflammatory Bowel Disease: A Cohort Study During the Biologic Era.

BACKGROUND Renal involvement can complicate the course of inflammatory bowel disease (IBD). In this study, we aimed to analyze the extent of renal manifestations in patients with IBD (Crohn disease or ulcerative colitis) during the biologic era. MATERIAL AND METHODS Patients diagnosed with and followed up for IBD for a period covering 16 years were retrospectively analyzed. Patients who received IBD diagnosis with clinical, endoscopic, and histopathological findings and were older than 18 years were enrolled in the study. Demographic, clinical, laboratory, and treatment data were retrieved from the patients' medical records. RESULTS Of the 1874 patients analyzed, the diagnosis was ulcerative colitis in 1055 patients and Crohn disease in the remaining 819. Renal manifestations were found in 105 patients (5.6%), 55 (6.7%) of whom were diagnosed with Crohn disease and 50 (4.7%) with ulcerative colitis. Renal calculi was the most common renal manifestation for both Crohn disease and ulcerative colitis. Renal manifestations were related to disease activity and surgical resection history in patients with Crohn disease, whereas no such relationship was found in patients with ulcerative colitis. CONCLUSIONS Renal manifestations may be seen in up to 6% of patients with IBD, and patients with Crohn disease seems to have more risk than do patients with ulcerative colitis. Nephrolithiasis is the most common form of renal involvement in IBD and is closely associated with disease activity. This relationship between IBD and renal manifestations should be considered, especially when there are subtle renal symptoms.

Safety of SARS-CoV-2 vaccination in patients with Behcet's syndrome and familial Mediterranean fever: a cross-sectional comparative study on the effects of M-RNA based and inactivated vaccine.

Most of the published data relate to classical forms of rheumatic diseases (RD) and information on rare inflammatory disorders such as Behçet's syndrome (BS) and familial Mediterranean fever (FMF) is limited. We studied the frequency of side effects and disease flares after COVID-19 vaccination with either Pfizer/BioNTech or Sinovac/CoronaVac in 256 patients with BS, 247 with FMF, and 601 with RD. Telephone interviews were conducted using a questionnaire survey in a cross-sectional design in patients with BS, FMF, and RD followed by a single university hospital. Study participants were vaccinated either with CoronaVac (BS:109, FMF: 90, and RD: 343,) or BioNTech (BS: 147, FMF: 157 and RD: 258). The majority have received double dose (BS: 94.9%, FMF 92.3% and RD: 86.2%). BioNTech ensured a significantly better efficacy than CoronaVac against COVID-19 in all patient groups (BS: 1.4% vs 10.1%; FMF: 3.2% vs 12.2%, RD:2.7% vs 6.4%). Those with at least one adverse event (AE) were significantly more frequent among those vaccinated with BioNTech than those with CoronaVac (BS: 86.4% vs 45%; FMF: 83.4% vs 53.3%; and RD: 83.3% vs 45.5%). The majority of AEs were mild to moderate and transient and this was true for either vaccine. There were also AEs that required medical attention in all study groups following CoronaVac (BS: 5.5%, FMF: 3.3%, and RD:2.9%) or BioNTech (BS: 5.4%, FMF: 1.9%, and RD: 4.7%). The main causes for medical assistance were disease flare and cardiovascular events. Patients with BS (16.0%) and FMF (17.4%) were found to flare significantly more frequently when compared to those with RD (6.0%) (p < 0.001). This was true for either vaccine. BS patients reported mainly skin-mucosa lesions; there were however, 11 (4.3%) who developed major organ attack such as uveitis, thrombosis or stroke. Flare in FMF patients were associated mainly with acute serositis with or without fever. Arthralgia/arthritis or inflammatory back pain were observed mainly in the RD group. Our study demonstrates that BS and FMF patients vaccinated with either CoronaVac or BioNTech demonstrated similar AE profile and frequency compared to RD patients. AEs that required physician consultation or hospitalization occurred in all study groups after either CoronaVac or BioNTech. Increased frequency of flares in BS and FMF compared to that seen in RD might reflect defects in innate immunity and deserves further investigation. Caution should be required when monitoring these patients after vaccination.

A novel fluorescent probe based on isocoumarin for Hg2+ and Fe3+ ions and its application in live-cell imaging.

Synthesis of the 2-amino-4-phenyl-6- (isocoumarin-3-yl) -3-cyanopyridine (APICP) containing both isocoumarin and pyridine ring in its structure was carried out, and this compound was characterized by ATR-FTIR, 1H NMR, and 13C NMR spectral techniques. A fluorescence sensor determining Hg2+ and Fe3+ ions in DMSO/HEPES buffer solution (9/1 v/v, 5 µM, pH 7.0) was developed using the synthesized compound, and the detection limits of the sensor with exquisite selectivity were calculated as 8.12 nM and 5.51 nM for Hg2+ and Fe3+ ions, respectively. Jobs plot method was used to determine the stoichiometry of APICP-Hg2+/Fe3+ complexes as 2:1 and FT-IR and ESI-MS methods confirmed the results. Besides, cell growth inhibitory potentials of the sensor over HepG2 cells and in vivo fluorescent cell imaging experiments were conducted. Findings revealed the relatively low cytotoxic effects of the synthesized sensor (IC50: 0.541 ±â€¯0.039 mM), and it could be utilized as an intracellular imaging agent for the determination of Fe3+ and Hg2+ ions in biological systems.

Haploidentical hematopoietic stem cell transplantation with post-transplant high-dose cyclophosphamide in high-risk children: A single-center study.

Recently, haploidentical transplantations have been performed with unmanipulated BM or PBSC. This approach is becoming more widely adopted with the use of PTCY. However, there is limited evidence about this approach in children. We present 15 children who received 16 haploidentical HSCT with unmanipulated BM or PBSC using PTCY for GVHD prophylaxis. Post-transplant CY(50 mg/kg IV) was given on the third and fifth day, and CsA or tacrolimus with MMF or MP was also used for GVHD prophylaxis. All patients engrafted at a median of 16 and 18 days for neutrophil and thrombocyte recovery, respectively. Grades II-III acute GVHD developed in seven patients, and mild chronic GVHD was found in two patients. Two patients died within the first 100 days due to sepsis (TRM 12.5%). Eleven patients are currently alive, with a median follow-up of 12 months (range 6-22 months). The 12-month OS and DFS were 75 ± 10.8% and 68.8 ± 11.6%, respectively. Our results with these high-risk patients are encouraging for haploidentical HSCT in pediatric patients. Future studies should continue to assess haploidentical HSCT, including comparison of other modalities, in a primary pediatric population.
