RESUMO
Background: Anemia occurs in majority of patients with chronic kidney disease despite adequate dialysis and iron replete status. This study was done to evaluate the effects of lactoferrin with or without iron supplementation for the treatment of anemia in patients with chronic kidney disease (CKD). Materials and Methods: In this prospective, observational, single-center, single-arm pilot study, adult patients aged >18 years, having stage 5 CKD (estimated glomerular filtration rate [eGFR] <15 ml/min/1.73 m2), and who had anemia (hemoglobin [Hb] <10 g/dl; transferrin saturation [Tsat] >20%) were included. Patients were treated with 100 mg of oral lactoferrin twice a day for one month with or without iron supplementation. Patients had been on stable erythropoietin doses for ≥1 month prior to inclusion in the study. We report on the improvement in Hb levels and effect on inflammatory markers from baseline at four weeks. Results: A total of 46 CKD patients having anemia were included. Patients had a mean age of 39.3 years, and a majority were men (69.6%). Improvement in the mean (SD) Hb level (g/dl) was observed from baseline (8.18 [1.19]) to Week 2 (8.54 [1.57]), which attained significance at Week 4 (8.96 [1.93]; P < 0.001; mean difference: -0.76; 95% confidence interval [CI]: -1.291 to - 0.2383). The improvement in Hb was higher in women than in men (P = 0.48) and in patients receiving lactoferrin with iron supplementation than in those receiving lactoferrin alone (P = 0.14). There was a non-significant decrease in the erythrocyte sedimentation rate (P = 0.14) and a non-significant increase in C-reactive protein (P = 0.54) level. Conclusion: Oral lactoferrin therapy was effective in improving hemoglobin levels in patients with advanced CKD and anemia. The effects of lactoferrin therapy on inflammatory markers remain uncertain.
RESUMO
Objectives: Chronic kidney disease (CKD) significantly increases the risk of infectious diseases (IDs), leading to heightened morbidity and mortality. However, there remains a lack of detailed, region-specific studies. This study investigates the clinical spectrum, etiologies, outcomes, and baseline predictors of mortality of ID emergencies in CKD patients in North India. Methods: This retrospective study was conducted at the Postgraduate Institute of Medical Education and Research, Chandigarh, from January 2021 to December 2022. It included patients aged ≥13 years with CKD and IDs admitted to the Acute Care and Emergency Medicine Unit. Results: We enrolled 248 patients (mean age 50 years, 58.1% males). About 60% had CKD stage 5, and 46% were on maintenance hemodialysis. Diabetic kidney disease was the predominant etiology (38.7%). The principal IDs were pneumonia (27.4%), urinary tract infection (UTI) (21.4%), sepsis of unknown primary focus (15.7%), tuberculosis (8.1%), and multisite infections (7.7%). Patients commonly have atypical clinical presentation, e.g., absence of fever and nonspecific symptoms such as shortness of breath and altered mental status. An emergence of multidrug-resistant organisms, e.g., Enterococcus faecium for UTI and Stenotrophomonas maltophilia for catheter-related bloodstream infections, was noted.In-hospital mortality rate was 33.5%, higher with multisite infections (58%) and pneumonia (47%). A low baseline Glasgow coma scale (GCS) was an independent predictor of mortality [odds ratio (OR) 0.786, 95% confidence interval (CI) 0.693-0.891, p-value <0.001]. Conclusion: Effective management and early intervention are needed to improve outcomes in CKD patients with ID emergencies, given the high mortality and atypical clinical presentations.

RESUMO
Primary membranous nephropathy (PMN), an autoimmune disease, is the most common cause of nephrotic syndrome in middle-aged non-diabetic adults. PMN pathophysiology includes Th1/Th2 paradigm. The IL-23/IL-17 pathway is implicated in autoimmune kidney disorders, but no study has examined its relationship with PMN. In several unrelated studies, PMN patients reported to have paradoxical IL-17 levels. This manuscript describes the best possible association of IL-23/IL-17 axis with PMN. Biopsy-proven PMN patients and age, gender-matched healthy controls were enrolled. Serum-PLA2R (Euroimmune, Germany), IL-23 and IL-17 (R&D; USA), was measured using ELISA along with biochemical parameters. Appropriate statistical tools were used for analysis. One hundred eighty-nine PMN patients (mean age 41.70 ± 12.53 years) and 100 controls (mean age 43.92 ± 10.93 years) were identified. One hundred forty were PLA2R-related. PMN patients had median proteinuria, serum albumin, and creatinine of 6.12 (3.875, 9.23) g/day, 2.32 (1.96, 2.9) g/dl, and 0.89 (0.7, 1.1) mg/dl, respectively. IL-17, but not IL-23, was significantly increased in PMN patients compared to controls (IL-17, median: 12.07 pg/ml (9.75, 24.56) vs median: 9.75 pg/ml (8.23, 17.03) p = 0.0002); (IL23, median: 6.04 pg/ml (4.22, 10.82) vs median: 5.46 pg/ml (3.34, 9.96) p = 0.142). IL-17 and IL-23 correlated significantly (p 0.05) in PMN patients, and similar trend was seen when grouped into PLA2R-related and -unrelated groups. The levels of IL-23 (p = 0.057) and IL-17 (p = 0.004) were high in MN patients that did not respond to the treatment. The current finding may indicate or suggest the involvement of IL-23/IL-17 PMN pathogenesis. A comprehensive investigation is needed to evaluate IL-23/IL-17 axis with renal infiltrating immune cells, and external stimuli.
RESUMO
Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiological phenomenon commonly associated with kidney diseases, especially chronic kidney disease. A consequence of endothelial dysfunction, PRES is usually associated with uncontrolled blood pressures and can rarely have atypical radiological findings involving the brain stem and spinal cord, called posterior reversible encephalopathy with spinal cord involvement (PRES-SCI). These atypical features may be confused with other etiologies causing a delay in diagnosis and management. We describe a young male patient who presented with neurological symptoms suggestive of PRES; however, the atypical radiological findings along with concomitant rapidly progressive glomerulonephritis led to a diagnostic dilemma. Repeat neuro-imaging after appropriate blood pressure control showed disappearance of the lesions confirming the diagnosis of PRES-SCI, and kidney biopsy showed advanced IgA nephropathy. Knowledge of atypical features of PRES is crucial amongst nephrologists as it is a common association with kidney disease and prompt identification and management avoid irreversible sequelae and unnecessary investigations.
RESUMO
For the foreseeable future, vaccines are the cornerstone in the global campaign against the Coronavirus Disease-19 (COVID-19) pandemic. As the number and fatalities due to COVID-19 decline and the lockdown anywise rescinded, we recognize an increase in the incidence of autoimmune disease post-COVID-19 vaccination. However, the causality of the most vaccine-induced side effects is debatable and, at best, limited to a temporal correlation. We herein report a case of a 51-year-old gentleman who developed Anti-Neutrophil Cytoplasmic Antibody (ANCA)-associated vasculitis (AAV) 2 week post-COVID-19 vaccination. The patient responded favorably to oral steroids and rituximab. Additionally, we conducted a case-based review of vaccine-associated AAV describing their clinical manifestations and treatment response of this emerging entity.

Surgical resection followed by radioactive iodine (131I) therapy constitutes a standard treatment for differentiated thyroid cancer. 131I is normally excreted through the kidneys, and treatment of patients with end-stage renal disease on hemodialysis requires special attention to the dose of 131I, the timing of dialysis, and radiation safety. We present a case of end-stage renal disease in a postthyroidectomy patient on hemodialysis who required radioactive iodine ablation, and we review the literature.

The preferential use of convective modes of hemodialysis (HD) for targeting hyper-cytokinemia state in sepsis-related acute kidney injury (AKI) has been questioned for its efficacy. Several studies have used predilution hemodiafiltration (HDF) in critically ill AKI patients with mixed results. In this study, we compared intermittent online postdilution HDF with the standard high-flux (HF) intermittent HD in non-critically ill patients with community-acquired (CA) AKI. In this pilot study, stable patients with CA AKI and systemic inflammatory response syndrome were included and given either postdilution online-HDF (OL-HDF) or standard HF HD outside intensive care units. The primary objectives were to assess the feasibility of conducting the study at a larger scale and to detect the differential impact of convective clearance on the rates of independence from dialysis at discharge or after 30 days. Plasma cytokine clearance was assessed as a secondary objective. Eighty consecutive AKI patients were randomized to receive dialysis in one of the treatment arms after fulfilling the eligibility criteria. The baseline parameters of clinical severity, etiology, and indications of dialysis, plus the baseline plasma cytokine profiles, were comparable. Moreover, 83% in the control arm and 71.1% in the intervention arm became independent from dialysis at discharge or at 30 days (P = 0.189). No survival advantage of postdilution OL-HDF was observed (P >0.05). Similar plasma cytokine clearance levels were noted in both arms. The current study confirms the feasibility; however, it does not support the preferential use of postdilution OL-HDF over HF-HD in non-critical patients.
