Abstract 4136654: Urine Output Response to a Furosemide Infusion is Associated with Acute Kidney Injury in Infants Following Cardiac Surgery

Background: Acute kidney injury (AKI) following cardiac surgery in infants is common and associated with longer mechanical ventilation times and length of stay. Prior studies have shown that a lack of responsiveness to bolus dose furosemide has been associated with increased incidence of AKI. However, these studies have excluded patients on continuous furosemide infusions who are often younger, more hemodynamically unstable, and at higher risk for AKI. Hypothesis: Decreased urine output after initiation of a furosemide infusion predicts development of AKI. Methods: A retrospective cohort study of infants (<1 year of age) was conducted who underwent cardiac surgery requiring cardiopulmonary bypass from 2020-2023 and were on a furosemide infusion post-operatively. The primary outcome was post-operative AKI as defined using KDIGO (Kidney Disease: Improving Global Outcomes) guidelines. A furosemide response score (FRS) was calculated using the total urine output divided by the total dose of furosemide administered over a given time. Univariate and multivariate analyses were performed, and receiver operating characteristic curves used to determine the discriminatory ability of the FRS with regards to the primary outcome. Results: A total of 155 infants (median age at surgery 9 days) were included. Overall, 77% of infants met definition for the primary outcome of AKI; 32% stage 1, 30% stage 2, and 15% stage 3. Lower FRS at 4, 10, and 24 hours after infusion initiation were associated with AKI development (p<0.0001). Younger age, smaller weight at surgery, lack of pre-operative feedings, pre-operative inotropic use and higher surgical complexity were also associated with a higher risk of AKI. An FRS (mL/mg/kg) cutoff of <11.3 at 4 hours, <25.5 at 10 hours, and <55.3 at 24 hours had good discriminatory ability (area under the curve 0.7-0.75) in predicting AKI stage 2 or 3 (p<0.001). Controlling for the significant univariate variables listed above, the FRS cutoffs remained an independent risk factor for the development of AKI stage 2 or 3, (p<0.01) and were significantly associated with longer mechanical ventilation days and length of stay. Conclusion: Lack of responsiveness to a furosemide infusion (as measured by urine output corrected for dose of furosemide) is associated with the development of AKI in a high-risk cohort of infants. These novel findings may be helpful to predict those at risk and allow for further investigations for modifiable risk factors.

Ketamine attenuates kidney damage and depression-like behaviors in mice with cisplatin-induced acute kidney injury

Acute kidney injury (AKI) is a serious condition characterized by decreased urine output, often accompanied by psychiatric symptoms like depression. However, there are limited pharmacological treatments available for AKI and its associated depressive symptoms. In this study, we investigated whether cisplatin-induced AKI in mice leads to depression-like behaviors and whether ketamine could alleviate both the kidney injury and these behaviors. Mice with cisplatin-induced AKI exhibited elevated levels of creatinine and urea, kidney damage, increased kidney injury molecule-1 protein, and pathological changes in the liver, colon, and spleen. They also showed depression-like behaviors and reduced expression of synaptic proteins in the prefrontal cortex. Remarkably, a single dose of ketamine significantly reduced these symptoms and pathological changes. Interestingly, the beneficial effects of ketamine on the kidneys, other organs, and depression-like behaviors, were reversed by the tropomyosin receptor kinase B (TrkB) inhibitor ANA-12. Western blot analysis revealed the involvement of the TrkB and ERK (extracellular signal-regulated kinase)-CREB (cAMP response element binding protein) signaling pathway. Additionally, metabolomics analysis indicated that blood metabolites, such as C16-ceramide, may contribute to the effects of ketamine in this model. These findings suggest that cisplatin-induced nephrotoxicity in AKI mice contributes to depression-like behaviors, and ketamine can alleviate both kidney damage and depression-like symptoms by modulating the TrkB and ERK-CREB signaling pathways, as well as altering blood metabolites. However, the role of the kidney-brain axis in these depression-like behaviors remains unclear. Furthermore, ketamine may have therapeutic potential for treating kidney diseases such as AKI, along with associated depressive symptoms.

Acute renal failure requiring renal replacement therapy secondary to rhabdomyolysis due to rosuvastatin

Introduction and importance: Statins are the group of medicines that lower the level of low-density lipoprotein cholesterol. One of the life-threatening complications is rhabdomyolysis as the use of these drugs. Case presentation: Here, we report a case of a 69-year-old female who was diagnosed with non-ST elevation myocardial infarction one month and was on regular medication before presentation with generalized weakness and decreased urine output. Proximal muscle weakness was greater than distal muscle on the bilateral lower limb, and power at the hip, knee, and ankle was 3/5 in the bilateral area, with absent reflex at the knee and ankle bilateral area. Clinical discussion: A total of four hemodialysis sessions were performed; the first three sessions were performed at an interval of 24 h, then the last maintenance hemodialysis after 48 h of three sessions. The patient’s weakness in the bilateral lower limb returns to normal condition. Conclusion: Physicians need to be aware of the potential of developing severe rhabdomyolysis in patients taking rosuvastatin to prevent morbidity, extended hospital stay, and financial loss.

Is platelet-rich plasma as safe as we think?: a case report

BackgroundPlatelet-rich plasma (PRP) is an autologous plasma product in which the concentration of platelets is several times higher than the physiologic level in peripheral blood and is a kind of concentrated form of platelet growth factor. It is widely used in dentistry, sports medicine, dermatology and cosmetology, gynecology and reproductive medicine, and ophthalmology. It has also been used in neurology for pain alleviation and regeneration of neurons. Herein, a 4-year-old patient, who was diagnosed with acute disseminated encephalomyelitis and received PRP subcutaneous injection was presented.Case presentationA 4-year-old patient, who was diagnosed with acute disseminated encephalomyelitis at the age of 3 years old and recovered with severe neurological sequelae despite treatment, received PRP subcutaneous injection in a private center to provide neuronal regeneration. The patient was admitted to our hospital 5 days after PRP with fever, refusal to feed, and decreased urine output. He was intubated due to respiratory distress. Inotropic treatments were initiated when hypotension and circulatory disturbance did not improve despite appropriate intravenous fluid administration. Staphylococcus epidermidis bacteremia was detected. Unfortunately, the patient died despite all interventions.ConclusionIn this case, it should not be ignored that the PRP procedure, which can be performed easily and quickly for various indications in many health institutions today, may be associated with serious side effects that may result in death. PRP injection must be performed in competent hands, following disinfection recommendations.

12616 Pembrolizumab-induced Autoimmune Adrenal Insufficiency: A Case Report And Literature Review

Abstract Disclosure: A. Calderon: None. E. Calderon-Martinez: None. J. Shakil, MD: None. A. Kansara: None. Immunechekpoint inhibitors (ICI)-related Primary Adrenal Insufficiency (PAI) is an uncommon entity. Compared to other endocrine-related adverse effects (irAES), antibody detection is less consistent. TPO and GAD65 antibodies are usually present in about 40-80% of the cases with hypothyroidism, hyperthyroidism, and diabetes. On the contrary, case reports and series for PAI seldom report the presence or absence of 21OH antibodies. We present a case and perform a literature review of PAI, in a patient who received pembrolizumab and developed PAI with 21 hydroxylase antibodies. A 62-year-old man with history HIV on ART (last CD4 count 590 cells/mm3) and locally advanced urothelial cancer on Pembrolizumab, presented with nausea, vomiting, abdominal pain, and decreased urine output. He was noted to be confused, and in hypoactive delirium. On admission, his chemistry panel he was noticed to have normal sodium and potassium levels. The CT scan of the abdomen revealed regional enteritis and was started on IV fluid therapy. His adrenal glands were described as normal on imaging. On the 16th day of hospitalization, the patient became unresponsive and hypotensive. He was transferred to the ICU. His sodium level was 132 mEq/L and potassium level was 6.1 mEq/L, bicarbonate level was 18 mEq/L, calcium of 10.3 mg/dl, and eosinophils of 15%. Random cortisol levels measured before administration of steroids were undetectable twice, 9 hours apart, with an ACTH level of 94. He underwent an ACTH stimulation test with cosyntropin 250 mcg IV with resulting undetectable cortisol levels after 30 and 60 minutes. CT and MRI of the brain showed no signs of hypophysitis. He was started on high-dose hydrocortisone with improvements in his mental status, hypotension, and gastrointestinal symptoms. He was discharged on hydrocortisone. His 21-Hydroxylase antibody was later found out to be positive. After combination immunotherapy regimens, CTLA-4 inhibitors are the most common to cause any irAE, however endocrine irAE particularly are mostly associated with PD-1 inhibitors. Among these, thyroid and pituitary disorders are the most common ones. Reports show that about 10% of patients receiving immunotherapy will develop endocrinopathy. ICI-induced PAI has been reported to occur in 7.6% of patients receiving combination therapy, and 2% of patients receiving Pembrolizumab. It has been reported that only 15% of patients will recover adrenal function. A meta-analysis that gathered 15 cases of ICI-induced PAI, found that only 2 cases had positive 21-hydroxylase antibodies. In our presented case, we have robust biochemical confirmation of PAI, with positive 21 hydroxylase antibody, after being on pembrolizumab for 9 months. Further information is needed to establish the pathophysiology, presentation, and prognosis of ICI-related PAI when anti adrenal antibodies are positive. Presentation: 6/1/2024

A Case of Decreased Urine Output with Loop Diuretics

A Case of Decreased Urine Output with Loop Diuretics

Effective calcineurin inhibitor treatment in adult-onset steroid-resistant nephrotic syndrome with a novel splice donor site variant of TRPC6: a case report.

Transient receptor potential canonical 6 (TRPC6) variants, which were initially detected in adult-onset familial focal segmental glomerulosclerosis (FSGS), were also identified in pediatric-onset one. Here, we present a patient with adult-onset steroid-resistant nephrotic syndrome (SRNS) who harbored a likely pathogenic TRPC6 variant and partially responded to calcineurin inhibitors (CNIs). A 44-year-old woman with stable rheumatoid arthritis, systemic lupus erythematosus, and Sjögren's syndrome was presented with nephrotic syndrome. Her renal biopsy results showed minor glomerular abnormalities. Upon admission, she was treated with steroids for around 4weeks, but it was ineffective. After 1-2weeks of cyclosporine A (CyA) administration, urine output increased, renal function improved without a decrease in proteinuria, and she was discharged. Her renal function was maintained for 2months, but after a CyA dose reduction, she was again admitted to the hospital due to relapsing edema, decreased urine output, and worsening renal function. CyA was replaced by tacrolimus (TAC). A second renal biopsy showed nearly the same findings as the first except for tubulointerstitial lesions. After 1-2weeks of TAC administration, urine output increased, and renal function improved. However, urinary protein levels did not decrease as before. After discharge, a whole exome analysis revealed a heterozygous splice donor site variant NM_004621.6;c.2644 + 1G > A in TRPC6. Genetic testing identified a novel splice donor site variant of TRPC6 in a patient with adult-onset SRNS, which prevented unnecessary steroid continuation. The safety and efficacy of CNI in TRPC6 glomerulopathy must be evaluated in future larger studies with longer follow-up.

Adult-Onset IgA Vasculitis Complicated by Kidney Failure at Disease Onset in a Nepalese Patient: A Case Report

Introduction: Immunoglobulin A (IgA) vasculitis, previously known as Henoch-Schönlein purpura, is an immune complex-mediated small vessel vasculitis primarily affecting children. While rare in adults, it can present with more severe manifestations, particularly involving the kidneys. This case report details the presentation and management of adult-onset IgA vasculitis with significant renal involvement.  Case Report: A 43-year-old male with a history of bipolar disorder presented with facial swelling, shortness of breath, and decreased urine output following an upper respiratory infection. Initial investigations revealed elevated blood pressure and renal impairment. Despite supportive treatment, his condition worsened, leading to a referral to a tertiary care center. He exhibited symptoms consistent with IgA vasculitis, including joint pain, rash, and nephrotic-range proteinuria. The diagnosis was confirmed through a skin biopsy and 24-hour urine collection. The patient was treated with intravenous methylprednisolone, oral prednisone, and an ACE inhibitor. His renal function improved with this regimen.  Discussion: Adult-onset IgA vasculitis can present with severe kidney involvement, including nephrotic-range proteinuria and elevated serum creatinine, which are associated with poorer outcomes compared to pediatric cases. The patient's management, involving glucocorticoids and an ACE inhibitor, aligns with current treatment recommendations for significant renal involvement. Long-term prognosis in adults remains challenging, with a higher risk of end-stage kidney disease compared to children. Vigilant monitoring and tailored treatment strategies are crucial for improving outcomes.  Conclusion: This case underscores the potential severity of adult- onset IgA vasculitis and highlights the importance of early diagnosis and aggressive management to mitigate long- term renal complications. Ongoing research is necessary to refine treatment approaches and enhance outcomes for adults with this condition.

A case report on primary hyperoxaluria type 1 in an infant

An alanine-glyoxylate aminotransferase (AGT) deficiency causes elevated oxalate levels in primary hyperoxaluria type 1 (PH1), a rare genetic disorder that can cause renal complications. We report the case of a 3-month-old male infant with respiratory distress, decreased urine output, and metabolic acidosis who was born to consanguineous parents. Bilateral nephrocalcinosis and severe metabolic disturbances were found during further examinations. Prompt identification and genetic validation for therapeutic interventions guided by PH1, such as peritoneal dialysis. The severity of PH1 was highlighted by difficulties maintaining renal function even after an initial improvement. To lessen the severe effects of PH1, this case highlights the significance of early diagnosis, genetic evaluation, and multidisciplinary management.

Neurological Manifestation of Neonatal Acute Kidney Injury: Focusing on the Clinico-Radiological Profile.

Purpose This study aimed atstudying the neurological manifestation of neonatal acute kidney injury, focusing on the clinico-radiological profile. Methodology In this cross-sectional study, newborns hospitalized in the neonatal intensive care unit of a tertiary care hospital were enrolled over a study period of one year. As per the Kidney Disease: Improving Global Outcome (KDIGO) criteria, 74 neonates were enrolled, and magnetic resonance imaging (MRI) was performed on the same neonates. Result In this study, acute kidney injury (AKI) was seen more often in neonates with admission weights between 1,500 and 2,499 grams, accounting for 52.7% of total study participants. In the current study, neonates admitted with AKI presented more with signs and symptoms of encephalopathy, such as lethargy (78.4%), seizures (64.8%), and irritability (35.1%) at admission. Signs and symptoms of fever and decreased urine output were more common after the first week of life. Abnormal MRI findings were observed in 64.9% of neonates with AKI. The mean blood urea and serum creatinine levels in neonates with abnormal MRI were 188.14 ± 108.25 mg/dL and 2.93 ± 2.16 mg/dL, respectively. The mean blood urea and serum creatinine levels in neonates with normal MRI were 169.84 ± 65.45 mg/dL and 2.41 ± 1.85 mg/dL, respectively. Of the 74 neonates enrolled with AKI, 12 (16.21%) had CSVT. These neonates had a mean blood urea level of 231.58 ± 111.66 mg/dL (p = 0.047) and a mean creatinine level of 3.77 ± 2.78 mg/dL. Conclusion Neonatal AKI has a variable presentation with high mortality and morbidity. Elevated serum urea and creatinine can be used to predict CSVT.

Risk factors of urolithiasis: A hospital-based retrospective study.

Urolithiasis is the most prevalent urinary tract disease, posing a global public health concern. The escalating prevalence and recurrence rates of urolithiasis are attributed to lifestyle modifications, such as reduced physical activity and dietary habits. This retrospective study aims to explore the risk factors associated with urolithiasis among individuals diagnosed with this condition. A retrospective hospital-based study involving 60 participants meeting the inclusion criteria was conducted. The participants were selected through convenience sampling from the urology, nephrology, and medical wards at Saveetha Medical College and Hospital. Demographic variables were collected, and the risk factors were assessed using a checklist on one-to-one interviews. The study unveiled that most participants (68%) were male. Eighty percent of participants had the risk factor of decreased water intake, 74% consumed excess tomatoes, 56% had a history of recurrent urinary tract infections, 64% consumed an excessive amount of salt daily, 72% experienced a decreased urine output, 53% had a habit of alcohol consumption, and 45% included milk and milk products in their daily diet. A small percentage (5%) had a family history of urolithiasis. Additionally, 6% were undergoing Siddha treatment. The findings from this study underscore the significant factors contributing to urolithiasis. They can inform public health campaigns to raise awareness about lifestyle modifications, dietary changes, and hydration protocols contributing to kidney stone formation.

Stevens–Johnson syndrome-toxic epidermal necrolysis overlap in a patient taking quetiapine and famotidine: a case report

BackgroundStevens–Johnson syndrome-toxic epidermal necrolysis (SJS-TNE) overlap is a rare skin disorder characterized by erythema, blisters, extensive exfoliation, epidermal detachment, the involvement of multiple mucosae, and positive Nikolsky’s sign. SJS-TEN has a high mortality rate. Our case involves a rare occurrence of drug-induced Stevens–Johnson syndrome-toxic epidermal necrolysis overlap with a delayed onset in the setting of quetiapine and famotidine therapy.Case presentationAn 82-year-old Taiwanese female was admitted to our hospital for decreased urine output, generalized edema, and multiple skin blisters and bedsores. With further spread of the lesions, multiple ruptured bullae with shallow erosions on the face, trunk, and limbs and mucosal involvement affected 20% of the total body surface area. Nikolsky’s sign was positive. A diagnosis of Steven–Johnson syndrome was highly suspected. One month prior, she had started famotidine and quetiapine. Intravenous methylprednisolone treatment was initiated, which ameliorated the skin lesions after 3 days. However, new lesions developed after only 1 day of methylprednisolone tapering. The patient died 12 days after admission.ConclusionStevens–Johnson syndrome-toxic epidermal necrolysis is a rare skin disorder. Although it is mainly acute and has a high mortality rate, delayed onset can still occur. Quetiapine and famotidine are generally safe and effective for treating geriatric and gastrointestinal problems, but rare drug hypersensitivity reactions can lead to debilitating consequences. Therefore, increased clinical awareness and the initiation of supportive care are imperative. Optimal management guidelines are still lacking, and confirmation of developed guidelines through randomized controlled trials is needed. Collaboration for better management strategies is warranted.

Early acute kidney injury in sepsis and septic shock

ABSTRACT Background: Acute kidney injury is one of the severe conditions in hospitalized patients. Acute kidney injury can develop early from admission, usually within the first 24 hours of ICU admission. In Vietnam, there have been limited studies monitoring the progression of acute kidney injury in the early stages. This study aims to investigate the incidence, severity, clinical, laboratory characteristics, and progression of acute kidney injury in patients with sepsis and septic shock within the first 48 hours. Methods: This study is a cross-sectional descriptive analysis of 101 patients who are 15 or older and have been diagnosed with severe infection and septic shock. These patients were treated in the Intensive Care Unit of Hue Central Hospital. The patient had treatment in accordance with a standardized protocol while being closely observed. Samples were collected for diagnostic testing, and the patient’s urine output and blood creatinine levels were diligently checked. Results: The prevalence of acute renal injury (AKI) was 60.40%, with stage 1 accounting for 50.82% of cases, stage 2 accounting for 22.95%, and stage 3 accounting for 26.23%. The cohort of individuals diagnosed with AKI exhibited an advanced age, with a mean age of 60.72 ± 17.41 years, and predominantly consisted of male subjects. Patients diagnosed with acute kidney injury showed a statistically significant decrease in urine output and an increased incidence of shock (p < 0.05). Additionally, these patients demonstrated lower levels of Hct, blood pH, and bicarbonate while exhibiting higher levels of blood urea, blood creatinine, AST, ALT, total bilirubin, PCT, and blood lactate (p < 0.05) compared to individuals without AKI. Patients with AKI had significantly elevated SOFA and APACHE II scores compared to individuals without AKI, as indicated by statistical analysis (p < 0.05). Upon admission, a significant proportion of patients, precisely 81.97%, experienced the development of AKI. Furthermore, a observation was made about the prompt recovery of these patients within the initial 24 and 48 hours following admission. Conclusion: The prevalence of AKI was accounted for 60.40%. Among the cases of AKI, stage 1 accounted for 50.82%, while stage 2 and stage 3 accounted for 22.95% and 26.23%, respectively. There were observed variations in urine output and rates of shock among individuals diagnosed with AKI. Additionally, SOFA and APACHE II scores were elevated. The percentage of AKI was 81.97% of patients upon their initial hospital admission, with a significant proportion seeing early recovery within the first 24 to 48 hours.

The interaction of net ultrafiltration rate with urine output and fluid balance after continuous renal replacement therapy initiation: A multi-Centre study.

PurposeDuring continuous renal replacement therapy (CRRT), a high net ultrafiltration rate (NUF) may worsen the decrease in urine output (UO) associated with starting CRRT. However, fluid balance (FB) may modulate this association. We aimed to examine the relationship between NUF, UO and FB at the start of CRRT. MethodsA retrospective cohort study of 1030 CRRT-treated patients admitted to two tertiary ICUs. ResultsMedian age was 60 years (IQR, 48–70), median APACHE III was 94 (IQR, 76–114) and median NUF rate was 0.7 mL/kg/h. In the 24 h after CRRT started, the mean hourly UO decreased from 25.5 mL to 11.9 mL (P < 0.001). Moreover, after adjusting for multiple confounders on multivariable analysis, a higher NUF was not significantly associated with a lower UO (−1.5 mL/kg for every 1 mL/kg/h increase in NUF; 95% CI -3.1 to 0.04; p = 0.064). In addition, pre-CRRT FB did not modulate the above relationship between higher NUF and lower UO. ConclusionA higher NUF rate was not significantly associated with a greater immediate and sustained reduction in UO after CRRT commencement. FB before CRRT was also not associated with a greater reduction in UO. These findings do not provide evidence for an effect of NUF on renal function.

Insights into Nephrotic Syndrome in Pediarics: Case Series Analysis

Nephrotic syndrome (NS) is one of the most common childhood kidney diseases. NS can affect children of any age from infancy to adolescence and predominantly occurs in the age group of 1–6 years. It is an illness caused by idiopathic diseases like minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS), membrane proliferative Glomerulonephritis, membranous Glomerulonephritis and is characterized by increased permeability across the glomerular filtration barrier. NS is classified as primary, secondary, and congenital. It consists of four clinical features like severe proteinuria, edema, hyperlipidaemia, hypoalbuminemia. The main cause of nephrotic syndrome are diseases associated with drugs and rarely genetic disorders. The pathogenesis of the disease affects various biological functions linked to loss of proteins negatively, which results in systemic complications which may be disease and drug-associated complications. Using drugs to treat NS leads to several complications which include improper growth, metabolism, behavior change inpatient. Itis a chronic relapsing disease for most of the steroid response drugs for treatment of nephrotic syndrome. Glucocorticoids, immunosuppressants and biological agents are used for the treatment of the diseases. In this case series, we presented a case series of nephrotic syndrome in pediatrics. Total 4 patients were taken into considerations. The patients came with a chief complaints of swelling of face, foamy urine, abdominal pain, dark coloured urine with decreased urine output, joint pains. The laboratory investigations for all the 4 patients showed that there were decrease in albumin levels (hypoalbuminemia), decrease in serum creatinine levels and protein in urine, although kidney biopsy couldn’t be perform but the diagnosis was made based on clinical and laboratory findings. The patients were mainly treated with prednisolone, pantoprazole, enalapril, nifedipine, amoxiclav, and even albumin transfusion were done. NS was successfully managed and fortunately the patients recovered.

Patients with Steroid Sensitive Nephrotic Syndrome: A Case Series

Nephrotic syndrome (NS) is one of the most common kidney diseases found in childhood. The prevalence of nephrotic syndrome worldwide is approximately 16 cases per 100,000 children with an incidence of two to seven per 100,000 children. Nephrotic syndrome may affect adults and children of both genders and any race. Nephrotic syndrome in children can be classified into three groups; secondary, congenital, infantile, and idiopathic. In first case, a 3-year-old male patient was presented with complaints of fever, cough for 6 days and swelling all over the body, decreased urine output, oral intake for 2 days, edema of face, body and tiredness for 3 days. Laboratory investigations showed elevated ESR, ferritin and lipid profile. Urine routine examination showed elevated urine albumin levels (+++). USG abdomen and pelvis conveyed right basal pleural effusion. In second case, a 4-year-old male patient was presented with complaints of facial puffiness, fever, breathing difficulty, abdominal distension and pain but no edema. He had history of right inguinal hernia and atrial septal defect. Cholesterol level was found to be elevated. Urine routine examination showed elevated urine albumin levels (+++). USG abdomen and pelvis showed mild ascites and right pleural effusion. Presenting third case, a 12-year-old female patient was presented with complaints of edema and decreased urine output. Patient had history of recurrent episodes of edema and decreased urine output for 11 months. Laboratory investigations showed elevated total cholesterol, declined LFT test and RFT test was found to be normal. Urine routine examination showed elevated urine albumin levels (+++), pus cells, RBC, granular cast and bacteria present. USG abdomen and pelvis indicate acute glomerulo nephritis and acute to moderate ascites. Here case series with 3 cases showed the sequence of nephrotic syndrome which is treated with corticosteroid with its side effects and cumulative dose of steroid in children.

Urinary liver-type fatty acid-binding protein level as a prognostic indicator of acute kidney injury secondary to severe falciparum malaria.

Acute kidney injury (AKI) secondary to severe falciparum malaria possesses a high mortality rate; however, a prognostic marker of renal dysfunction has not yet been identified. Thus, we reported a case of a patient with AKI secondary to falciparum malaria who underwent hemodialysis and a renal biopsy due to prolonged renal dysfunction. The male patient, in his 50s, presented to our hospital with vomiting, diarrhea, fever, and decreased level of consciousness. The Giemsa-stained peripheral blood film revealed approximately 5% parasitemia, and a rapid diagnostic test was positive for Plasmodium falciparum. He was diagnosed with severe falciparum malaria and was started on quinine hydrochloride. Hemodialysis was initiated due to the decreased urine output and fluid retention. Subsequently, he was weaned off hemodialysis. The histopathological analysis of a renal biopsy revealed interstitial fibrosis, tubular atrophy, and chronic inflammatory cell infiltration; thus, malarial nephropathy was diagnosed. Thereafter, his renal function stabilized, and he was discharged from the hospital. The urinary liver-type fatty acid-binding protein (L-FABP) level decreased before renal function improved. Our report highlighted that long-term follow-up is essential for severe AKI secondary to malaria. The urinary L-FABP level may be a useful prognostic indicator of AKI secondary to severe falciparum malaria.

Acute Liver Failure with Intracerebral Hemorrhage in Dengue Fever: A Rare Clinical Presentation

Dengue is the major cause of arthropod-borne viral disease in the world. It presents with high fever, headache, rash, myalgia, and arthralgia and it is a self-limiting illness. Severe dengue can occur in some cases resulting in dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). We present a case of a young patient aged 25-year-old male who presented with fever, jaundice, decreased urine output for 5 days, and altered mental status for the last 1 day. After investigation, he was diagnosed with dengue fever and later developed sepsis-induced acute liver failure with acute kidney injury. The patient was treated with intravenous antibiotics and hemodialysis. Plasmapheresis was done in view of acute liver failure. Gradually patient condition improved and he gained consciousness. But later on, the patient developed spontaneous intracerebral hemorrhage (ICH) and the patient succumbed to his illness after 2 days of developing ICH. ICH is a very rare and atypical manifestation in the case of severe dengue patients, research for effective treatment is crucial now.

Fatal Triad: Spontaneous Pneumothorax, Pneumomediastinum, and Pneumorrhachis in a Case of Paraquat Ingestion

Objective: Dependency on agriculture and the unregulated sale of paraquat makes it an easy alternative for homicidal and suicidal use in developing nations. It kills by multiorgan failure, predominantly pulmonary fibrosis, and ARDS. We report a case of alleged paraquat ingestion with spontaneous pneumothorax, spontaneous pneumomediastinum, and pneumorrhachis. Aim is to reinforce the importance of a high index of suspicion in early diagnosis when the above findings are present with ARDS in absence of trauma and a history of alleged substance ingestion. Case Presentation: A 35-year-old male presented with loose stool occasionally bloody, oral ulcers, yellow discoloration of eyes with fever, and decreased urine output for three days after consuming some substance with his seafood. On examination, he had yellow discoloration of eyes and oral mucosa along with multiple ulcers on the buccal region as well as the dorsum of the tongue and lateral margins with generalized subcutaneous emphysema. In addition, decreased air entry in the bilateral lung field and muffled heart sounds were present. He had an acute hepatorenal failure and severe metabolic acidosis with respiratory failure. Urine tested positive for myoglobin and muscle enzymes (creatinine kinase and lactate dehydrogenase (LDH)) were raised. He was intubated and shifted to the intensive care unit. Injectable N-acetyl cysteine (NAC) for acute liver failure was started with empirical antibiotics and intravenous fluids. We supplemented thiamine and vitamin K, and hemodialysis was done in view of progressive renal failure. Radiological evaluation showed spontaneous pneumothorax, pneumomediastinum, and pneumorrhachis which were managed conservatively. His respiratory parameters worsened despite maximal ventilatory support. Renal failure and metabolic acidosis worsened in spite of hemodialysis. He succumbed to his illness on day five of admission and seven days after toxin ingestion. Conclusion: We recommend that the sale of paraquat be restricted and regulated to avoid its use for suicidal and homicidal purposes. More research is required to find measures to intervene early and prevent pulmonary fibrosis. We propose that paraquat toxicity be considered early in a patient with the triad in an atraumatic setting with acute respiratory distress syndrome (ARDS).

Rapidly Progressive Renal Failure in Young Adult: An Atypical Presentation of Multiple Myeloma - A Case Report

Introduction: Patients frequently present with renal impairment that does not fit the criteria for acute kidney injury or chronic kidney disease. This condition, known as rapidly progressive renal failure (RPRF), encompasses a diverse range of clinical syndromes characterized by the progressive renal impairment over days to weeks. Case Report: We present a case of a 37-year-old male with a short history of uremic symptoms and decreased urine output with no significant history or examination findings except pallor. The patient had a creatinine of 1.6 mg/dL in April 2022, rising to 4.4 mg/dL, then 11.6 mg/dL during May, 17.6 mg/dL in June, presented to us with a creatinine of 24.6 mg/dL, with normal kidney size and corticomedullary differentiation (CMD). Beta-2-microglobulin was elevated, and renal biopsy showed features suggestive of multiple myeloma (MM). Atypical appearing tubular casts showing 3+ patternless staining for kappa light chains and negativity for lambda light chains were observed. The patient was started on chemotherapy for MM, and renal function was gradually improving. Conclusion: Renal failure as the sole presentation of MM is rare, especially in young adults. This case emphasizes an atypical RPRF, particularly given the patient’s young age.
