Introduction: The ongoing pandemic of COVID-19 has led to severe disruption of healthcare services worldwide. We conducted this study to assess the impact of COVID-19 pandemic on the management of Systemic Lupus Erythematosus (SLE) patients who were enrolled in the nation-wide inception cohort. Methods: A questionnaire was administered to the SLE patients enrolled in the inception cohort. Questions related to the effect on disease activity, preventive measures adopted against COVID-19, the incidence of COVID-19, hardships faced in getting access to health care professionals and availability of medicines, adherence, fear of COVID-19 and the potential benefits of being part of the registry. Results: A total of 1040 (90% females) patients completed the questionnaire. The mean age was 27.5 ± 19.1 years and the mean disease duration was 1.25 years. Twenty-Four (2.3%) patients had developed fever (>1 day) during this period, including one patient with additional symptoms of diarrhoea and anosmia, however, none of the patients developed COVID-19 infection. 262 patients (25.2%) reported financial difficulty during this period and patients reported an average excess expenditure of at least 2255.45 INR ($30) per month. 378 patients (36%) reported problems in getting their prescribed medicines due to lockdown. Of these, 167 (40%) patients needed to change their medication schedule due to this non-availability. Almost 54% of patients missed their scheduled follow up visits during the lockdown period and 37% of patients were unable to get their investigations done due to closure of laboratories and hospitals. 266 patients (25.5%) reported worsening of various symptoms of SLE during this period. Almost 61% patients felt confident that being associated with the inception cohort had helped them in managing their disease better during this period of lockdown as they received help in the form of timely and frequent telephonic consults, assistance in making the medicines available, and regular counselling resulting in abetment of their fears and anxieties. Conclusion: The current COVID-19 pandemic has made a huge impact on our SLE patients. Patients faced difficulty in the availability of medicines, missed the doses of medicines, had financial constraints, and spent more money on health during the pandemic.

Background: Mitochondrial transplantation (MTx) has emerged as a novel therapeutic strategy, particularly effective in diseases characterized by mitochondrial dysfunction. This review synthesizes current knowledge on MTx, focusing on its role in modulating immune responses and explores its potential in treating post-cardiac arrest syndrome (PCAS). Methods: We conducted a comprehensive narrative review of animal and human studies that have investigated the effects of MTx in the context of immunomodulation. This included a review of the immune responses following critical condition such as ischemia reperfusion injury, the impact of MTx on these responses, and the therapeutic potential of MTx in various conditions. Results: Recent studies indicate that MTx can modulate complex immune responses and reduce ischemia–reperfusion injury post-CA, suggesting MTx as a novel, potentially more effective approach. The review highlights the role of MTx in immune modulation, its potential synergistic effects with existing treatments such as therapeutic hypothermia, and the need for further research to optimize its application in PCAS. The safety and efficacy of autologous versus allogeneic MTx, particularly in the context of immune reactions, are critical areas for future investigation. Conclusion: MTx represents a promising frontier in the treatment of PCAS, offering a novel approach to modulate immune responses and restore cellular energetics. Future research should focus on long-term effects, combination therapies, and personalized medicine approaches to fully harness the potential of MTx in improving patient outcomes in PCAS.

Vagus Nerve Stimulation (VNS), a neuromodulation technique of applying controlled electrical impulses to the vagus nerve, has now emerged as a potential therapeutic approach for ischemia-reperfusion insults. It provides a pivotal link in improving functional outcomes for the central nervous system and multiple target organs affected by ischemia-reperfusion injury (I/RI). Reduced blood flow during ischemia and subsequent resumption of blood supply during reperfusion to the tissue compromises cellular health because of the combination of mitochondrial dysfunction, oxidative stress, cytokine release, inflammation, apoptosis, intracellular calcium overload, and endoplasmic reticulum stress, which ultimately leads to cell death and irreversible tissue damage. Furthermore, inflammation and apoptosis also play critical roles in the acute progression of ischemic injury pathology. Emerging evidence indicates that VNS in I/RI may act in an anti-inflammatory capacity, reducing oxidative stress and apoptosis, while also improving endothelial and mitochondrial function leading to reduced infarct sizes and cytoprotection in skeletal muscle, gastrointestinal tract, liver, kidney, lung, heart, and brain tissue. In this review, we attempt to shed light on the mechanistic links between tissue-specific damage following I/RI and the therapeutic approach of VNS in attenuating damage, considering both direct and remote I/RI scenarios. Thus, we want to advance the understanding of VNS that could further warrant its clinical implementation, especially as a treatment for I/RI.

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.
