ABSTRACT
Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease and one of the most common causes for end-stage renal disease (ESRD). Kidney transplantation is the optimal renal replacement therapy for ADPKD patients complicated with ESRD. Currently, scholars at home and abroad have a certain controversy about whether polycystic kidney resection is necessary in ADPKD patients before kidney transplantation, and the criteria and methods for polycystic nephrectomy also differ. To further standardize the clinical technical operation of kidney transplantation in ADPKD patients, experts in organ transplantation organized by Branch of Organ Transplantation of Chinese Medical Association formulated this specification from the aspects of diagnosis of ADPKD, indications and contraindications of kidney transplantation for ADPKD, preoperative evaluation and treatment, polycystic nephrectomy, and postoperative management, etc.
ABSTRACT
Tenapanor is a novel phosphorus-lowering drug, which mainly inhibits sodium/hydrogen exchange protein 3 (NHE3), and also reduces intestinal phosphorus absorption by down-regulating the expression of sodium phosphate co-transporter protein (NAPI). Tenapanor is mainly used for the treatment of hyperphosphatemia in patients with end-stage renal disease-hemodialysis (ESRD-HD). Diarrhea is the most common adverse reaction to this product. This article reviews Tenapanor by performing a literature search on its pharmacological effects, pharmacokinetic properties, clinical evaluation, safety, drug interactions and dosage.
ABSTRACT
Primary hyperoxaluria type Ⅱ (PH2) is an inherited disorder of the glyoxylate metabolism caused by the gene mutation of glyoxylate reductase/hydroxypyruvate reductase (GRHPR). PH2 is characterized by recurrent nephrolithiasis and nephrocalcinosis, which may even progress into end-stage renal disease. Currently, organ transplantation is the only treatment option for PH2, which mainly includes two strategies: kidney transplantation and combined liver and kidney transplantation. Kidney transplantation yields a high risk of recurrence of oxalate nephropathy, which may cause early graft dysfunction. Combined liver and kidney transplantation could mitigate the deficiency of oxalate metabolism, whereas it yields a high risk of graft complications. PH2 is an extremely rare disorder. No consensus has been reached on the indications, surgical selection and perioperative management of organ transplantation for PH2 patients. In this article, the pathogenesis, diagnosis, monitoring and organ transplantation experience of PH2 were reviewed, aiming to divert clinicians' attention to PH2 and provide reference for determining diagnosis and treatment regimens, especially transplantation strategy for PH2 patients.
ABSTRACT
Doppler ultrasonography is the main modality for imaging of hemodialysis AV ?stula as it is safe and non-invasive. This study is to measure the Arterio-venous (AV) ?stula blood ?ow during early postoperative period (0–7days) and assess its role in AV ?stula failure prediction. Doppler ultrasonography was used to estimate the blood ?ow in the AV ?stula of 50 patients at (0–7days) after the ?stula was made. The blood ?ow in ?stula during early postoperative period for ?stula failure was evaluated, and long term failure was predicted. Blood ?ow rates Method measured in arteriovenous ?stula created in upper extremity were measured in ?rst week and sixth week post-operative. Results After follow up evaluation out of 50 patients, 40 ?stulas considered to be matured; 10 considered failed. 30% failure were males and 70% were female. In early post operative period, cut off was set at 182 ml/min and the sensitivity of blood ?ow for prediction of ?stula failure is 98%, speci?city 90 %, PPV 95% and NPV 90%. Measurements of the AV ?stula blood Conclusion ?ow in proximal artery and draining vein with its diameter of lumen were noted in the early postoperative period has a role predicting AV ?stula failure. There is risk of failure if the blood ?ow less than 182 ml/min (day 0–7)
ABSTRACT
Objective To investigate the clinical manifestations, treatment and prognosis of primary hyperoxaluria type 1 (PH1). Methods Relevant literature review was conducted from Chongqing VIP, CNKI, Wanfang Data, PubMed, Web of Science, Embase and Cochrane databases. Clinical data of 57 patients with PH1 were collected, and the clinical manifestations, diagnosis and treatment and prognosis were analyzed. Results A total of 35 eligible studies were searched, including 57 patients with PH1, 39 male and 18 female, aged 0.2-57.0 years old, and the age of onset was from date of birth to 42 years old. The specificity of clinical symptoms of 57 patients with PH1 was relatively low, including 41 cases of renal stones, 21 cases of renal calcification and/or calcium deposition, 12 cases of oxalic acid deposition outside the urinary system, 12 cases of lumbago, backache and abdominal pain, and 8 cases of ureteral stones. Besides, alternative symptoms, such as decreased urine output, metabolic acidosis, disorder of water and electrolyte, anemia and gross hematuria were also reported. Thirty-three patients were diagnosed with end-stage renal disease (ESRD) upon admission. Twenty-six patients received transplantation. Among them, 17 cases underwent kidney transplantation (2 cases repeatedly received combined liver-kidney transplantation due to recurrence of stones and resumption of dialysis, and 1 case repeatedly received liver transplantation due to resumption of dialysis), 7 cases received combined liver-kidney transplantation, 2 cases underwent liver transplantation, and 3 cases received sequential liver-kidney transplantation, respectively. Thirty-one patients did not undergo transplantation. Significant differences were observed in the survival rate between patients treated with and without transplantation (85% vs. 58%, P < 0.05). Conclusions Clinical manifestations of PH1 are diverse and lack of specificity. A majority of PH1 patients are diagnosed with ESRD upon admission. Clinical prognosis of patients undergoing transplantation is better than that of those counterparts without transplantation. Prior liver transplantation or combined liver-kidney transplantation is recommended.
ABSTRACT
Abstract Fabry disease is a metabolic alteration linked to an enzymatic deficiency of Alpha-Galactosidase A, this disorder compromises the sphingolipid metabolism, leading to an accumulation of lysosomal globotriaosylceramide and is inherited in an X-linked recessive way. The diagnostic of this disease, in general, requires the confirmation of below-normal levels of Alpha-Galactosidase A obtained from dried blood spot (DBS) samples, followed by an assessment of the enzyme in leukocytes. We aimed to report the Alpha-Galactosidase A values obtained in Colombian males with end-stage renal disease (ESRD) screened using dried blood spot samples during ten years. This screening was performed with samples sent to the analysis center from 6156 patients between 2006- 2016. All patients with low levels in enzyme activity (compared to the control population) were sent to confirmation through enzyme analysis in isolated leukocytes. 26 males (0.42%) with low levels of Alpha-Galactosidase A were identified (Range 0.0 - 1.14 nmol/ml/hour, cut-off: 1.15), 22 patients were subsequently measured in isolated leukocytes having a confirmation of Fabry disease in 5 patients (0.08% of total male population) (Range: 0.3 -4.7 nmol/mg prot/h). These results are similar to those reported in studies with comparable characteristics being this the first reporting frequency of Fabry disease among Colombian males with end-stage renal disease.
ABSTRACT
Autosomal dominant polycystic kidney disease (ADPKD) is a common monogenic hereditary kidney disease, which can progress into end-stage renal disease (ESRD). Patients with ADPKD constantly suffer from recurrent intracapsular infection. The drug resistance caused by antibiotic treatment is becoming increasingly prominent. The pattern of renal transplantation should be selected according to the infection of polycystic kidney disease. In this article, the origin of renal cyst, classification and source of cystic fluid, type and drug resistance of bacteria in the cystic fluid, and intracapsular infection of patients with renal transplantation- associated ADPKD were reviewed, aiming to provide reference for the diagnosis and treatment of intracapsular infection of patients with ADPKD.
ABSTRACT
ABSTRACT Background: The reported incidence and fatality rates of SARS-CoV-2 infection in patients receiving maintenance dialysis are higher than those of the general population. Objective: This study sought to characterize the clinical characteristics and outcomes following COVID-19 infection in this population in a single center in Brazil. Methods: Out of 497 dialysis patients evaluated between March 1st, 2020 and February 1st, 2021, those presenting symptoms or history of close contact with COVID-19 patients were tested. Disease severity was categorized as mild, moderate, or severe. Results: Out of the 497 patients, 8.8% tested positive for COVID-19. These patients were predominantly male (59%), mean age 57.5 ± 17. Hospitalization was required for 45.4% of patients and 15.9% received mechanical ventilation. Symptoms such as fever, cough, dyspnea and asthenia were more frequent in the severe group. Neutrophil to lymphocyte ratio, C- reactive protein, glutamic oxalacetic transaminase and lactic dehydrogenase were significantly higher in the severe group, while hemoglobin and lymphocyte counts were significantly lower. Chest CT >50% of ground glass lesions was the risk factor associated with severe disease and need for hospitalization. The incidence of a thromboembolic event was of 22.7% in this population. The incidence, mortality, and case fatality rates were 954.4/10,000 patients, 151.8/10,000 patients, and 15.9%, respectively. Conclusions: The incidence, mortality and case fatality rates in our cohort were significantly higher than those reported for the general population. To institute appropriate control measures and early vaccination in dialysis facilities is imperative to prevent the spread of COVID-19 infection.

Deficiency in vitamin D and cognitive dysfunction commonly are associated together in patients suffering from chronic kidney disease (CKD) in both dialysis and non-dialysis patients, vitamin D develop new protective regulatory roles in the functions of CNS. Combination of low levels of vitamin D and CKD can be enrolled for devastating and lead to sever cognitive dysfunction. Patients with CKD mostly associated with Hypovitaminosisand moreover common in elderly patients and related with cognitive decline, one of the hypotheses that CKD patients commonly have a low level of vitamin D and have potential experience in accelerated cognitive decline which rarely link on this topic. Most of CKD patients particularly sensitive for developing in the deficiency of vitamin D. Reduce vitamin D intake, male absorption in compromised GIT patients, loosing of vitamin D binding protein with urine, and α-hydroxylase enzyme reduction in the kidney all are the risk factors included in the causes of 25(OH) D vitamin decrease production. Aim of study: assess cognitive function by using one validated score: trial making test B in patients with CKD in both dialysis and non-dialysis. Patients and methods: a total of 54 patients with CKD and 57 patients with ESRD on hemodialysis enrolled in this study, where CKD defined as GFR < 60 ml/min by MDRD study. Exclusion criteria include CVA, deaf and blind, and low education patients. Cognitive functions assessment done for patients who are on hemodialysis and non- dialysis by using trial B testing, this second assess spatial scanning concentration and executive function by time measuring that needed to connect the series of numbered that are sequentially and littered circles. Catastrophic shorter time completion with a maximum of 300 second indicates better performance. 25 (OH) D vitamins has assessed from each patients using direct immunoassay method, with assay at 4-110 ng/ml. Results: for patients on hemodialysis 27 (39.7%) has deficient 25(OH) D vitamin status 25 (36.7%) insufficient,20 (29.4%) had sufficient vitamin D levels, significant low level in patients on hemodialysis in comparison to those with non-hemodialysis. Trial making test B score was significantly lower in dialysis patients, significant correlation between cognitive function assessment (trial making test B) and low vitamin D level. Conclusions: the prevalence of deficiency in vitamin D in CKD especially hemodialysis patients associated with cognitive decline.

Introduction: Malnutrition is common in patients withEnd Stage Renal Disease (ESRD) on Hemodialysis (HD).Depending on the parameter measured, the prevalence ofmalnutrition in the chronic dialysis population ranges from 10to 54%. It is related with the secretion of a number of proteins(adipokines), including leptin and adiponectin and alsocytokines such as IL-6. This study was planned with the aimof reviewing the association of nutritional status with serumleptin and CRP levels in hemodialysis patients.Material and methods: The present study was conducted inthe department of Medicine at Chattrapati Shivaji SubhartiHospital from August 2017 to March 2019; consisted of50 patients of End stage Renal Disease on maintenancehemodialysis admitted in Chattrapati Shivaji Subharti Hospitalduring the time period.Results: Out of the 50 subjects, 35 (70%) were male and15 (30%) were females. The Lean Body Mass (%) in thestudy subjects was 59.76±5.92. The overall mean leptinlevel distribution among the subjects was 1.51±0.36. Theoverall mean CRP level distribution among the subjects. was3.75±0.47. A positive correlation was found between CRPand BMI with statistical significance as p<0.05 (table 11).Similarly a highly positive correlation was found betweenLeptin and BMI as p<0.01.Conclusion: Our study point to possible use of serum leptinand CRP concentration as an indicator of nutritional status inHD patients based on observed significant positive correlationbetween serum leptin and CRP concentrations with BMIvalues.
ABSTRACT
Objective: To explore the patterns of cerebral structural abnormalities and cognitive function alterations in end-stage renal disease (ESRD) patients undergoing maintenance hemodialysis, and the underlying correlative factors. Methods: Thirty-seven ESRD patients undergoing maintenance hemodialysis without prior stroke in Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine were selected. All patients underwent brain magnetic resonance imaging (MRI) and assessment of cognitive function by using Mini-Mental State Examination (MMSE). Patients were divided into lacunar infarction group (n=33) and non-lacunar infarction group (n=4), or white matter hyperintensities (WMH) group (n=14) and non-WMH group (n=23). The difference of demographic characteristics, past history, blood parameter and dialysis adequacy between patients and their controls were analyzed by t test, Mann-Whitney U test, χ2 test and Fisher exact test. Spearman correlation analysis were performed to explore the relationship between clinical features, cerebral structural abnormalities and cognitive function. Results: Nineteen male and eighteen female patients participated in the study. The mean age was (59.4±12.3) years. The incidences of lacunar infarction and WMH were 89.2% and 37.8%, respectively. 24.3% of the participants were diagnosed as cognitive impairment. Patients with lacunar infarction were elder, who had lower level of hemoglobin, hematocrit, serum albumin and serum total protein, while parathyroid hormone (PTH), erythrocyte sedimentation rate, tumor necrosis factor-α and interleukin-6 were elevated. Patients with WMH were also significantly elder, lower in transferrin saturation and higher in PTH. The differences between the two groups were statistically significant (all P<0.05). Spearman correlation analysis showed MMSE score had a negative correlation with age (r=-0.471, P=0.003) and had positive correlations with education status (r=0.355, P=0.031) and hypertension (r=0.358, P=0.030). The study did not find the relationship among lacunar infarction, WMH and MMSE score; however, recall function was found negatively correlated with lacunar infarction (r=-0.357, P=0.030). Conclusion: ESRD patients undergoing maintenance hemodialysis have a high prevalence of cerebrovascular disease and cognitive impairment. Older age, anemia, inflammation status, chronic kidney disease-mineral and bone disorder may be the influencing factors of the cerebral structural abnormalities and cognition decline.
ABSTRACT
Background: CKD is a major health problem associated with high morbidity and mortality. Chronic kidney disease is end result of long standing cases of diabetes mellitus and hypertension. There is paucity of data, regarding spectrum of CKD. CKD is generally asymptomatic in early stages. Early interventions delay the progression to ESRD, thus reducing morbidity and mortality. Objectives: To study the Clinical profile, Biochemical profile and determine the Aetiology of chronic kidney disease among Rural population. Methods: In this study, we retrospectively analysed data of 161 patients admitted in hospital over a period of six months. Data was collected based on clinical assessment, laboratory analysis and Radiological investigations to determine aetiology of chronic kidney disease. Results: 161 patients of chronic kidney disease were included in the study. The mean age of all patients studied was 47.20±16.16 years. The most common aetiology was hypertensive nephropathy. Most of the patients presented with, pedal oedema (59.6%) followed by Oliguria (52.2%), facial edema (46.9%). Conclusion: The major causes of CKD in descending order were hypertension, Type 2 diabetes mellitus, chronic glomerulonephritis and obstructive uropathy. So if we are able to detect and treat these conditions in early phase, we can prevent further progression and damage to the kidney.
ABSTRACT
Background: Chronic kidney disease can progress to end-stage kidney failure (ESRD), which is fatal without artificial filtering (dialysis) or a kidney transplant.Methods: The ESRD patients of either gender age >18 years who were diagnosed by nephrologist as ESRD and are on haemodialysis regularly included for the study.Results: The blood urea, serum creatinine, phosphorous, potassium levels were reduced significantly in post – haemodialysis condition, but, there was not much weight reduction after haemodialysis. Serum albumin, serum sodium and blood haemoglobin levels were almost unchanged in post – haemodialysis state. There was no significant difference between the pre and post haemodialysis parameters- serum Na+ serum albumin and blood hemoglobulin. Out of 75 ESRD patients, almost all patients 74 (98.7%) prescribed tablet Livogen, 73 (97.3%) patients given Inj. EPO, 55 (73.3%) tab Nicardia, 54 (76%) tab Sodamint, 43 (57.3%) capsule Alpha D3, 40 (53.3%) tab Shelcal. While between 12 (16%) to 20 (26%) patients prescribed tab Nodosis, tab Metoprolol, tab Febuget, tab Ecosprin, and tab Rantac. Only 1 (1.3%) to 9 (12%) patients received tablet Augmentin, tab Arkamine, tab Carvedilol, tab Para 500, tab Atorvas, Human mixtard, tab Calcicard, tab Minipress XL, tab Dytor, and tab Clopilet.Conclusions: The available two models of treatment, i.e., haemodialysis and poly pharmacy at hospital setup to face the challenges associated with the ESRD, and even outcome after application of both these two models of therapies did not provide optimal normal healthy life status to ESRD patients.
ABSTRACT
Introduction: Patients with end-stage renal disease (ESRD) are treated with hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD).Non-infectious complications of CAPD are increasing in relative importance due to success in decreasing the rate of peritonitis. Aims and objectives: Our aim was to study the non-infectious complications in patients of ESRD on CAPD and to study the impact of the non-infectious complications in the survival of CAPD catheters. Materials and Methods: A prospective study has been conducted at Regional institute of medical science, Imphal in a total of 71patients of ESRD who are already on CAPD or newly diagnosed ESRD who have undergone CAPD catheter implantation. Their detailed history, clinical examination and relevant laboratory investigations were done and the different non-infectious complications were identified and analysed. Result: Out of the 71 patients studied 39 patients had complications like hypokalemia (15 patients), omental wrap (10 patients), catheter tip migration (6 patients), haemoperitonium (2 patients), hydrothorax (2patients), exit site leak(2patients), abdominal wall edema (1patient), catheter block(1patient). Conclusion: In our study the most common non-infectious complication was hypokalemia followed by omental wrap and catheter tip migration. Knowledge about the common prevalent non-infectious complications of CAPD alerts the treating doctor to take up the specific corrective steps at an earlier stage, thus preventing the morbidity associated with the same. We conclude that the majority of non-infectious complications in these patients were treatable and did not interfere with the catheter survival.
ABSTRACT
Introduction: Diabetic kidney disease (DKD) representsone of the most frequent microvascular complications ofdiabetes with an overall prevalence of approximately 40% intype 2 diabetes population. Microalbuminuria is one of themost serious problems in type 2 DM. Vildagliptin, DPP-4inhibitors, is a novel oral anti-diabetic drug for the treatmentof type 2 diabetes mellitus (T2DM). The objective of the studywas to evaluate the therapeautic efficacy of vildagliptin onmicroalbuminuria in type 2 diabetes mellitus.Material and methods: We included in our study 103 T2DMpatients with microalbuminuria. Exclusion criteria: NSAIDsinduced nephropathy, Lupus nephropathy, Polycystic KidneyDisease, Medullary Sponge Kidney, All causes of nephriticand nephrotic syndrome, ESRD due to diabetes mellitus andmoderate to severe hepatic failure. We measured UrinaryACR value of parameters at 0,3.6,9,12 months respectively.Vildagliptin was given to those patient and was observed thatafter giving vildagliptin was there any change in albumin tocreatinine i.e microalbuminuria.Result: The mean of ACR baseline (mean±s.d.) of patientswas 125.1436 ± 58.810 with range 50.7000 - 298.0000 and themedian was 100.0000. The mean of ACR of 3, 6, 9, 12months(mean±s.d.) of patients were 110.3184 ± 57.5647, 106.7340 ±48.8492, 103.7252 ± 45.6745, 95.4466 ± 62.342 respectively.Association of ACR in five groups was not statisticallysignificant (p=0.6118).Conclusion: We found that after 12 months of therapy withvildagliptin, a DPP-4 inhibitor, there was some reduction ofACR and it is approximately 30%
ABSTRACT
PURPOSE: Cardiac changes in end-stage renal disease are the most common causes of death after kidney transplantation (KT). Chronic kidney disease presents a major risk factor for the development and progression of diastolic dysfunction. The purpose of this study was to identify the association between changes in left ventricular (LV) diastolic function and perioperative clinical factors in patients with preserved ejection fraction following KT. MATERIALS AND METHODS: We reviewed 115 patients who underwent KT between January 2011 and December 2015 with both preand post-transplant echocardiograms; patients with LV systolic dysfunction were excluded. LV diastolic function was measured using the ratio of early transmitral flow velocity to early diastolic velocity of the mitral annulus (E/e′). RESULTS: Patients with normal pre-operative LV systolic function (n=97) showed improvement in E/e′ after KT (11.9±4.4 to 10.5±3.8, p=0.023). Additionally, post-KT estimated glomerular filtration ratio was associated with changes in E/e′ (odds ratio, −0.056; 95% confidence interval, −0.014 to −0.007; p=0.026). Among patients with preexisting diastolic dysfunction (20/97 patients), the amount of intraoperative fluid administration was related to E/e′ changes (odds ratio, 0.003; 95% confidence interval, 0.000 to 0.005; p=0.029). CONCLUSION: KT is associated with improved diastolic function. Post-KT renal function was significantly related to changes in LV diastolic function. The amount of intraoperative fluid was a risk factor for worsening diastolic function after KT in patients with preexisting diastolic dysfunction.

Introduction: The prevalence of metabolic syndrome and of type 2 diabetes is extremely pronounced in Asian countries, particularly in India. In 2015, over 0.9 million deaths in India were attributed to diabetes directly or indirectly and approximately 60-70% suffering from renal diseases.Materials and Methods: This study conducted at School of Medicine, D Y Patil University, Navi Mumbai included 241 type II diabetic patients with diabetic duration 3-5 years, between age 30-70 years. Blood samples were processed for renal parameters and RT-PCR to check the expressions and polymorphisms of IL-6, IL-10, CD 36 and LDLr.Results: Gene analysis of IL10, CD 36 and LDLr showed that IL10, it is expressed and seen mutation at 56 A mutated to T. In CD 36 expressions were seen and amplified region showed mutation at 67 T to C (heterozygous). In LDLr both expressions and mutations of base pairs seen in higher amounts and amplified region showed mutation at 329 C to CC; 350 A to G; 352 A to G; 353 A to G; 355 A to T; 356 G to T; 358 GG to T (deletion of one nucleotide) and 563 G to T.Conclusion: Relationship between T2DM microalbumin and lipid parameters were not decisive and may be superseded by gene expressions and polymorphisms of IL10, CD 36, and LDLr. Early measurement of polymorphisms and expressions may prevent morbidity and mortality after therapeutic intervention and lifestyle modification. Association of cytokines may help in the development of novel biomarkers to identify individuals at risk.
ABSTRACT
Objective: To explore the changes of pyruvate dehydrogenase (PDH) activity and pyruvate dehydrogenase kinase 4 (PDK4) expression in the end-stage renal disease (ESRD) patients' skeletal muscles. Methods: Skeletal muscle samples were collected from non-chronic kidney disease (non-CKD) patients and ESRD patients. PDH activity was detected by ELISA assay. Real-time qPCR was performed to examine gene transcription levels of PDK1-PDK4 and PDH subunits. Western blotting analysis was used to detect protein expression levels of PDK1 and PDK4. Results: There were no demographic differences between two groups of patients. Plasma creatinine and urea nitrogen were significantly elevated in ESRD group (both P<0.05), while estimated glomerular filtration rate, hemoglobin and plasma albumin in ESRD group were significantly lower than those in non-CKD group (all P<0.05). Skeletal muscle PDH activity in ESRD group was markedly lower than that in non-CKD group (P=0.014). There were no differences in PDK1-PDK4 and PDH subunits mRNA transcription levels between ESRD and non-CKD group. PDK4 protein expression was significantly higher than that in non-CKD group (P=0.000). Conclusion: The decreased PDH activity in ESRD patients' skeletal muscle may be related to up-regulation of PDK4.

ABSTRACT
@#<p style="text-align: justify;"><strong>BACKGROUND:</strong> Lupus nephritis is very common complications in SLE, with clinical symptoms of renal involvement occurring in 30%-70% of patients. Outcomes in children with proliferative lupus nephritis (PLN) show 9-15% progress to end-stage renal disease (ESRD) at 5 years.</p><p style="text-align: justify;"><strong>OBJECTIVES:</strong> This study compared the outcome of children and adolescent patients with lupus nephritis treated with 9 month versus 6 month induction of cyclophosphamide therapy. Renal frequency and adverse effects of IV cyclophosphamide during and after induction therapy were described and determined.</p><p style="text-align: justify;"><strong>DESIGN:</strong> Retrospective Cohort Study</p><p style="text-align: justify;"><strong>SETTING:</strong> Tertiary Hospital</p><p style="text-align: justify;"><strong>METHODS:</strong> Retrospective cohort study comparing 6 and 9 month protocol of IV cyclophosphamide for lupus nephritis were conducted in a government tertiary pediatric hospital in the Philippines. A total of 39 patients with lupus nephritis were gathered, 23 patients underwent 6 months and 16 patients underwent 9 months protocol.</p><p style="text-align: justify;"><strong>RESULTS:</strong> The comparison of two protocols in the administration of intravenous cyclophosphamide (IVCY) did not show significant difference between the two in terms of changes in GFR levels, but some evidence of a greater percent increase from baseline with the 6 months protocol post treatment were observed. Among 39 subjects, creatinine, albumin and urinalysis profile did not also differ between the two groups and levels within each group changed insignificantly over time up to 24 months. Proportion of subjects with renal flare ups, adverse effects and who expired during the study period were also essentially similar between the two groups.</p><p style="text-align: justify;"><strong>CONCLUSION:</strong> IV Cyclophosphamide seems efficacious if given at the very beginning of the flare and at the start after patient was diagnosed with lupus nephritis. No statistically difference between the duration of the protocol. Renal flare ups and adverse effects of cyclophosphamide such as nausea, vomiting and headache were observed similarly between two protocols. Diligent follow up is needed for further studies and specificity of the results.</p>
