Nowadays, schizophrenia is treated with atypical antipsychotics that can determine neuroleptic malignant syndrome or rhabdomyolysis appearance. In addition to trauma and muscular hypoxia, there are ...some drugs and toxins associated with rhabdomyolysis development, among which olanzapine. A case of severe rhabdomyolysis syndrome, with extremely high levels of serum creatine kinase (CK), followed by acute kidney failure, secondary to olanzapine overdose and prolonged immobilization is outlined. Continuous renal replacement therapy was performed, with a slow clearance of serum CK levels. Under supportive therapy, systemic alkalinisation with volume resuscitation and corticotherapy, patient’s general condition was improved, as well as his lower limb paresis. He followed frequent psychiatric evaluations and psychotherapies, before and after being transferred to a medical service. Rhabdomyolysis diagnosis is difficult in mild cases due to non-specific signs and symptoms, but it also has some typical manifestation, generically called “the rhabdomyolysis syndrome triad”. The treatment is usually supportive; renal replacement therapy is required in the presence of acute kidney injury unresponsive to aggressive volume resuscitation. The systemic myoglobin release is responsible for renal injury. Olanzapine muscle toxicity can lead to severe rhabdomyolysis syndrome complicated with acute kidney injury and multiple organ dysfunction syndrome. Rapid identification and aggressive therapeutic management are essential for improving patients’ outcome and prevent the occurrence of irreversible injuries.

IgA Nephropathy (IgAN) is one of the most frequent types of glomerulonephritis encountered in adults from Western countries and Asia. IgAN is responsible for approximately 40% of end-stage renal ...disease (ESRD) mediated by glomerular impairment. The majority of adult IgAN patients present a slowly progressive pattern towards ESRD. Current types of treatment are based mainly on supportive care: i.e., life style risk factors, measures that lower blood pressure and reduce proteinuria, weight loss, smoking cessation or glycaemia control. Because IgAN is an immune complex-mediated disease, immunosuppression therapy gains more and more attention as a modality of treatment. Despite the beneficial effects, the value of immunosuppression remains controversial due to high rates of adverse reactions. The aim of this review is to highlight the benefits and limitations of promoting immunosuppression in IgAN with mild to moderate proteinuria despite supportive antiproteinuric therapy up titrated to maximum tolerated doses.
The latest treatment guidelines for patients with arterial hypertension continues to indicate as the first line therapy a minimal association between renin-angiotensin system (RAS) blockers and a ...thiazide-type or a thiazide-like diuretic. In addition, according to 2018 ESC/ESH (European Society of Cardiology/European Society of Hypertension) guidelines for the management of arterial hypertension, a mineralocorticoid receptor antagonist may be added in resistant hypertension cases (uncontrolled hypertension under at least 3 classes of antihypertensive drugs including a RAS blocker, thiazide diuretic and a calcium channel blocker) for general population. For chronic kidney disease (CKD) patients, achieving the optimal blood pressure (BP) level can be difficult because high complication rates can be encountered in any antihypertensive class mentioned, especially for RAS blockers and mineralocorticoid receptor inhibitors. This brief review aims to highlight the importance of diuretics use in CKD patients and the boundaries of their usage.
Hospitalized COVID-19 patients often develop acute kidney injury (AKI), leading to increased mortality. In order to improve patients’ survival rate, it is important to understand the pathophysiology ...mechanism of AKI. In this brief review, we highlight the most important elements of the etiology and pathophysiology of COVID-19 associated AKI. Acute tubular injury seems to be more frequent than prerenal azotemia in COVID-19 patients and collapsing glomerulopathy is the most encountered form of glomerular disease. Another important role in acute kidney injury seems to play immune cell infiltration, inflammation, endothelial injury and microvascular thrombi. Renin-angiotensin-aldosterone system is also important in the pathophysiology of COVID-19 associated AKI.
Impaired renal function artificial support development massively contributed to increased life expectancy and quality of life improvement. The first steps in this direction were made in the beginning ...of the 1900s, nowadays existing a variety of methods of renal replacement therapies that could be customized to each patient depending on the associated complications and comorbidities. Considering these aspects and that acute kidney injury (AKI) could represent a life-threatening condition, the present review will present different options of renal replacement therapies suitable to be initiated in emergency.
Immunoglobulin A (IgA) nephropathy is one of the most common glomerulonephritis. Its clinical manifestations vary from asymptomatic forms to cases with nephritic syndrome or nephrotic-range ...proteinuria. The prognosis depends on the level of proteinuria, decline of glomerular filtration rate and control of blood pressure. The pathognomonic histological changes are represented by the granular IgA deposits in the mesangium. The treatment consists of comprehensive support care and immunosuppressive therapy. We discuss the case of a 50-year-old man who presented microscopic hematuria, nephrotic-range proteinuria and decreased renal function, exacerbated in the last 6 months prior the admission. We performed a renal biopsy and granular deposits were present in the glomerular mesangium that were highly suggestive for IgA nephropathy. Immunosuppressive therapy was instituted immediately, but the decline of the renal function continued and renal replacement therapy was needed. Patients with poor prognosis have an unsatisfactory response to the immunosuppressants, especially those with a delayed diagnosis.
As COVID-19 pandemic continues to test the medical world, due to rapid viral transmission and subsequent mutations, the old burning health crisis continues to surface, one of them being the blood ...shortage. The current situation has disrupted the fragile balance between blood donors and the real need of blood in hospitals, especially due to repetitive lock-downs, isolation, social-restrictions, and ongoing anxiety promoted by social media, threatening the quality of medical cares.
The limited antifungal drugs available and the rise of multidrug-resistant Candida species have made the efforts to improve antifungal therapies paramount. To this end, our research focused on the ...effect of a combined treatment between chemical and photodynamic therapy (PDT) towards a fluconazole-resistant clinical Candida albicans strain. The co-treatment of PDT and curcumin in various doses with fluconazole (FLC) had an inhibitory effect on the growth of the FLC-resistant hospital strain of C. albicans in both difusimetric and broth microdilution methods. The proliferation of the cells was inhibited in the presence of curcumin at 3.125 µM and FLC at 41 µM concentrations. The possible involvement of oxidative stress was analyzed by adding menadione and glutathione as a prooxidant and antioxidant, respectively. In addition, we examined the photoactivated curcumin effect on efflux pumps, a mechanism often linked to drug resistance. Nile Red accumulation assays were used to evaluate efflux pumps activity through fluorescence microscopy and spectrofluorometry. The results showed that photoactivated curcumin at 3.125 µM inhibited the transport of the fluorescent substrate that cells usually expel, indicating its potential in combating drug resistance. Overall, the findings suggest that curcumin, particularly when combined with PDT, can effectively inhibit the growth of FLC-resistant C. albicans, addressing the challenge of yeast resistance to azole antifungals through upregulating multidrug transporters.
Background: Anemia and iron deficiency are two of the main public health problems worldwide, associated with negative outcomes in surgical patients. This experimental study aimed to create a model of ...acute iron deficiency with anemia through blood loss and extensive surgery. Afterwards, intravenous iron was administered to correct the iron deficiency and to improve the hematological parameters in distinct moments regarding the surgical time. To assess the optimum time for therapeutic intervention, experimental subjects were compared, performing clinical, paraclinical, and histological examinations, as well. Methods: Male rats (n = 35), aged 11–13 months, were randomly designated into six groups. Anemia and iron deficiency were obtained through a 15% blood volume loss, followed by major surgical intervention (femur fracture and osteosynthesis using Kirschner wire). Therapeutic intervention was obtained with an intravenous ferric carboxymaltose infusion, as follows: group II: intraoperative (n = 7), group III: 48 h after surgery (n = 7), group IV: 48 h before surgery (n = 5), and group V: seven days before surgery (n = 6). Group I (n = 5) was left anemic, while group 0 (n = 5) was nonanemic without therapeutic intervention. Results and Discussion: In group I, serum iron lower than in group 0 (27.04 ± 6.92 μg/dL versus 60.5 ± 2.34 μg/dL), as well as hemoglobin (10.4 ± 0.54 g/dL versus 14.32 ± 2.01 g/dL) and ferritin values (22.52 ± 0.53 ng/mL versus 29.86 ± 3.97 ng/mL), validated the experimental model. Regarding wound healing after surgical trauma, we observed that neovascularization was more significant in group III, followed by group V, with fewer neutrophils, a well-represented and rich in lymphomonocytes inflammatory infiltrate associated with the biggest collagen fiber dimensions. The periosteal reaction and callus area presented thicker trabeculae in groups II and III compared to the anemic group. Conclusions: This original experimental study assessed the effect of perioperative intravenous iron administration at a specific time by comparing the weight, hematological, and iron status-defining parameters, as well as histological characteristics of the included subjects. The present findings highlight that correcting the iron deficiency in emergency settings through intravenous iron administration intraoperatively or 48 h postoperatively could determine the improved bioumoral parameters, as well as a better evolution of the postoperative wound and bone healing compared to the anemic group or subjects that received therapeutic intervention 48 h before surgery.
Acute disseminated encephalomyelitis is an inflammatory, immune-mediated disease of the central nervous system (CNS) that usually appears in the first nine years of life, commonly following an ...infection or vaccination. We report the case of a middle-aged female, with history of recent perpetual infections, with neurologic symptoms masked by a severe septic shock and subsequent multiple organ failure. Although in adults the prognosis is more severe, and there are various reported cases with unfavorable evolution, following corticosteroid and physical therapy, our patient was able to recover an important part of her neurological deficits.
