Effect of Executive Function on Health-Related Quality of Life in Children with Chronic Kidney Disease.

Introduction: As the highest function in the brain that regulates our daily activity, executive dysfunction might affect someone's health-related quality of life (HRQoL), especially in those with chronic diseases, including chronic kidney disease (CKD). Neurocognitive functions, including intelligence quotient (IQ) and executive function can be affected through various mechanisms in CKD. However, there was still no specific study regarding how IQ and executive function might affect HRQoL in children with CKD. Purpose: To assess Executive Function's impact on HRQoL and to find association between treatment modalities and CKD stages with HRQoL in children with CKD. Methods: A cross sectional study was conducted at Pediatric Nephrology Clinic at Hasan Sadikin General Hospital, Bandung, Indonesia from September 2022 to April 2023. We included 38 children whose age range were 6-16 years 11 months old with CKD stage III - V. Assessment tools used were: BRIEF questionnaire for executive function; WISC III tool for IQ; PedsQLTM questionnaire generic module for HRQoL. Data was analyzed using SPSS ver. 26.0. Results: Total number of samples was 38. Complete examinations were done on 30 patients. Eight other patients did not undergo the IQ test. There was a negative correlation between executive function components scores (GEC, BRI, MI) with HRQoL scores on parents' proxy in all domains. We found no correlation between HRQoL and IQ scores, but we found a correlation between IQ and CKD stage. There was a significant difference in HRQoL from the children's perspective among the three modalities; children who underwent conservative treatment were having the best HRQoL scores. Conclusion: Interventions to improve executive function of children with CKD should be done to improve their HRQoL in the future. Early diagnosis and treatment of CKD should be done at the earliest to improve neurocognitive function and HRQoL.

Case Report: Iatrogenic trauma of the bladder due to long-term unidentified intrauterine device malposition inside the bladder with rectovesical fistula.

According to reports, there are 1.9-3.6 incidences of IUD migration and uterine perforation for every 1000 IUD insertions. It is important to note that bladder perforation caused by a misplaced IUD is uncommon and is thought to happen most frequently during insertion. Here, we describe a patient who presented with symptoms related to the malposition of IUD inside the bladder. It is feasible to draw the conclusion that the cystoscopy technique should be taken into consideration as a suitable therapy option for such injuries in this organ. When a problem cannot be effectively treated by cystoscopy alone, laparotomy should be considered.

C-reactive protein and haemoglobin level in acute kidney injury among preterm newborns.

Aim To explore the possibility of C-reactive protein (CRP) and haemoglobin (Hb) in prediction and risk assessment of acute kidney injury (AKI) among preterm newborns. This is believed to be closely related to the incidences of AKI, and could be the most affordable in early detection of AKI. Methods A case control study was carried out at Dr Hasan Sadikin Hospital in Bandung with a total of 112 preterms divided into two groups: with and without AKI based on the neonatal KDIGO (Kidney Disease: Improving Global Outcomes). CRP and creatinine serum were measured within 6 hours and at 72-96 hours after birth. The routine blood count included haemoglobin, haematocrit, leucocyte, and thrombocyte in the first 24 hours of life. Results CRP increase was the most influential factor for AKI with sensitivity of 80.6% and specificity of 60.2%. An increase in CRP >0.04 had an aOR (95% CI) of 5.64 (1.89-16.84). Haemoglobin <14.5 g/dL had slightly increased aOR (95% CI) of 1.65 (1.05- 8.63) Conclusion CRP increases >0.04 and level Hb <14.5 g/dL showed acceptable as an early warning for AKI in preterm newborns.

The level of transforming growth factor-ß as a possible predictor of cyclophosphamide response in children with steroid-resistant nephrotic syndrome.

BACKGROUND: Steroid-resistant nephrotic syndrome (SRNS) is a burden in the country due to the progressive severity of chronic kidney disease (CKD). Calcineurin inhibitors (CNIs) or monoclonal antibodies are currently recommended for the treatment of this disease. In developing countries, steroid and cyclophosphamide (CPA) are available drugs used during the treatment. This study aims to provide a non-invasive modality that can be used to predict the response of SRNS children to CPA therapy. Subsequently, the proteinuria duration was shortened to reduce the risk of glomerular damage. The present study aims to determine whether there is a correlation between baseline serum TGFB and proteinuria in SRNS children six months after receiving CPA treatment. The author hypothesized that there would be a negative correlation between those variables. METHOD: A prospective-cohort-study was conducted at Hasan Sadikin General Hospital Bandung, Indonesia. A total of 88 SRNS children, aged 1 to 18 were accessed for serum TGF-ß level before receiving CPA therapy for six months, and clinical signs were observed. Furthermore, after six months of CPA treatment, the subjects were divided into CPA responder and non-responder based on the presence of proteinuria, then the data were analyzed using multiple logistic regression to adjust age and gender. RESULTS: There was a statistically significant relationship between TGF-ß and the risk of non-response to CPA therapy, after accounting for age, gender, baseline GFR, baseline ureum, and baseline urinary protein, the adjusted-OR was 1.051 (95% CI 1.007, 1.097, p = 0.022). CONCLUSION: The high level of serum TGF-ß obtained prior to CPA administration are reliable data for estimating adverse results on CPA therapy. Based on these results, a high baseline TGF-ß level correlates with the poor response of CPA therapy.

The association of rs187238, rs19465518 and rs1946519 IL-8 polymorphisms with acute kidney injury in preterm infants.

BACKGROUND: Interleukin 18 (IL-18) promoter polymorphisms (-656G > T, -607C > A, and -137G > C) affect serum IL- 18 (sIL-18) levels and are associated with renal injury. PURPOSE: This study aimed to determine the diagnostic utility of sIL-18 and urine IL-18 (uIL-18) as biomarkers for acute kidney injury (AKI) and analyse the association of IL-18 polymorphisms to AKI in preterm infants. METHODS: Blood and urine samples were collected from 56 preterm infants with AKI and 56 without AKI to measure serum creatinine (SCr), sIL-18, and uIL-18. Genotyping of polymorphisms was performed and analysed, with AUC-ROCs analysis used to evaluate the diagnostic utility of s-/uIL-18 levels. RESULTS: The median sIL-18 and uIL-18 levels were significantly higher than those without AKI. For a cutoff of >132 pg/mL, the sIL-18 expression had sensitivity and specificity of 80.36% and 60.71%, respectively, while for uIL-18, a cutoff of >900.7 pg/mL had sensitivity and specificity of 51.79% and 78.57%, respectively. The odds ratio of sIL-18 and uIL-18 to predict AKI in preterm infants was 5.89 (95%CI:2.31-15.02) and 4.15 (95%CI:1.58-10.89), respectively. The polymorphisms -137G > C and -656G > T were significantly associated with sIL-18 expression. CONCLUSION: Serum and urine IL-18 levels are risk factors for and a moderate predictor of AKI in preterm infants.

The Effect of Exogenous Superoxide Dismutase (SOD) on Caspase-3 Activation and Apoptosis Induction in Pc-3 Prostate Cancer Cells.

BACKGROUND: This study aimed to assess the effects of exogenous SOD administration on prostate cancer cell line (PC-3) apoptosis via the intrinsic pathway by examining the expression of manganese superoxide dismutase (MnSOD), caspase-3, and apoptosis index of the PC-3 cell line. METHODS: We used the prostate cancer cells from secondary prostate cancer cell lines (PC-3) derived from castration refractory prostate cancer (CRPC), cell differentiation grade IV, and had metastasized to the bone from the American Type Culture Collection (ATCC, Rockville, MD, USA). Superoxide dismutase (SOD) is derived from extracts of melon seeds and wheat gliadin biopolymer, and divided into 62.5 mg/mL, 83 mg/mL, 125 mg/mL, and 250 mg/mL doses. Expression of MnSOD was measured by immunohistochemistry (IHC). Expression of caspase-3 was measured using Western Blot method. Apoptotic index is calculated based on the reaction introduction 3OH end of fragmentation of DNA by the enzyme terminal transferase in preparations with TUNEL staining reagents. A one-way ANOVA test and Pearson correlation test were used to determine the relationship between SOD with expression of caspase-3 and apoptotic index. RESULTS: SOD extract significantly increased the expression of caspase-3 (P=0.016) and the apoptotic index (P=0.000) (P<0.05). There was a correlation between the increased doses of SOD extract and the apoptosis index (P=0.015; r=0.679) and between the increased caspase-3 expression and the apoptosis index (P=0.015; r=0.682). CONCLUSION: Administration of superoxide dismutase (SOD) increased apoptosis in a prostate cancer cell line (PC-3) through the increased expression of caspase-3. Superoxide dismutase (SOD) can be considered as a therapy for late-stage prostate cancer that had been progressed to hormone resistant and metastasized and promote apoptosis in those prostate cancer cells.

Potential role of ACE2-related microRNAs in COVID-19-associated nephropathy.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for coronavirus disease (COVID-19), potentially have severe kidney adverse effects. This organ expressed angiotensin-converting enzyme 2 (ACE2), the transmembrane protein which facilitate the entering of the virus into the cell. Therefore, early detection of the kidney manifestations of COVID-19 is crucial. Previous studies showed ACE2 role in various indications of this disease, especially in kidney effects. The MicroRNAs (miRNAs) in this organ affected ACE2 expression. Therefore, this review aims at summarizing the literature of a novel miRNA-based therapy and its potential applications in COVID-19-associated nephropathy. Furthermore, previous studies were analyzed for the kidney manifestations of COVID-19 and the miRNAs role that were published on the online databases, namely MEDLINE (PubMed) and Scopus. Several miRNAs, particularly miR-18 (which was upregulated in nephropathy), played a crucial role in ACE2 expression. Therefore, the antimiR-18 roles were summarized in various primate models that aided in developing the therapy for ACE2 related diseases.

Urinary Cytochrome C and Caspase-3 as Novel Biomarker of Renal Function Impairment in Unilateral Ureteropelvic Junction Obstruction Model of Wistar Rats.

INTRODUCTION: Prolonged obstruction in UPJO would lead to kidney destruction. It is important to find a non-invasive biomarker for early detection of renal impairment before definitive treatment for UPJO. In this study, we aim to evaluate the role of urinary cytochrome c and caspase-3 as a novel biomarker to predict renal function impairment in a UPJO model in Wistar rats. METHODS: Twenty-five male Wistar rats were separated into 3 groups. Group I consists of 5 rats without any treatment or model, group II consists of 5 rats (sham group), and group III consists of 15 rats with the unilateral partial ureteral obstruction model. After 4, 15, and 21 days of observation, the urine was collected and rats were sacrificed to collect the glomerular count in the kidney. Measurement of cytochrome c and caspase-3 was done using the ELISA method, while the glomerular count was done using a light microscope. Data were analyzed using factorial repeated measures ANOVA test and correlation test with Pearson and processed using SPSS version 20.0. RESULTS: The UPJO group has a significant increase in cytochrome c concentration and caspase-3 concentration compared to the control group and sham group (p<0.05). There was a significant decrease in the normal glomerulus count of the UPJO group (p<0.05). There was a significant relationship between the decrease in glomerulus count with the concentration of cytochrome c and caspase-3 in the UPJO group. CONCLUSION: There was a significant relationship between the decrease in glomerulus count with the increase in the concentration of cytochrome c and caspase-3 in the UPJO group.

Low-Dose Maintenance Intravenous Iron Therapy Can Prevent Anemia in Children with End-Stage Renal Disease Undergoing Chronic Hemodialysis.

Iron deficiency anemia is common in children with end-stage renal disease (ESRD) on long-term hemodialysis receiving erythropoiesis-stimulating agents. One approach to maintain the iron profile and hemoglobin levels is maintenance therapy with regular low doses of intravenous (IV) iron after initial iron repletion therapy; however, evidence for the benefits of this approach is lacking. This study evaluated the effect of IV iron maintenance therapy on anemia in children on regular hemodialysis. This retrospective cohort study included 41 pediatric ESRD patients with normal hemoglobin and iron status who underwent regular hemodialysis at the Pediatric Dialysis Unit of Cipto Mangunkusumo Hospital, Indonesia, between January 2015 and April 2019. Among these, 21 received IV iron maintenance therapy with two doses of 2 mg/kg of IV iron sucrose every 2 weeks (the treatment group) and 20 did not (the comparison group). Changes in hemoglobin and transferrin saturation were assessed after 6 weeks of observation and compared between the two groups. There was a significant reduction in the mean hemoglobin level compared with the baseline level in the comparison group (21 g/L; 95% CI, 9.3-33 g/L; p=0.001) but not in the treatment group (0.7 g/L; 95% CI, -6.6-8 g/L; p=0.84). The risk of anemia was lower in the treatment group (relative risk = 0.42; 95% CI, 0.22-0.79; p=0.003). Although majority of the patients had high baseline ferritin level, this study indicates that in our setting, ferritin may not be a reliable parameter to review the iron status, as it can be affected by chronic inflammation. Hence, the decision to start IV iron maintenance therapy in patients with hyperferritinemia should consider the patient's clinical condition and morbidity. To conclude, the coadministration of IV iron maintenance therapy is beneficial for maintaining hemoglobin levels and preventing anemia in children with ESRD who are undergoing regular hemodialysis, have achieved the target hemoglobin levels, and have normal iron status.

Malignant priapismus induced by adenocarcinoma of the prostate.

Penile metastasis of adenocarcinoma of prostate is an extremely rare clinical entity and even less of such cases presenting with malignant priapism. Management of priapism with penile shunting is recommended in this case. No consensus beyond personal recommendation from other studies found in this case due to the relative rarity of the disease and the associated lack of data. In this study, we present a case of malignant priapism due to penile metastasis of adenocarcinoma of the prostate, an extremely rare clinical entity and a more uncommon site of metastasis.

Complicated Urinary Tract Tuberculosis in a 13-Year-Old Adolescent with Chronic Kidney Disease and Antituberculous Drug-Induced Hepatotoxicity.

Urinary tract tuberculosis (TB) is a rare extrapulmonary manifestation of TB in children. The disease is potentially underdiagnosed because it clinically resembles other urinary tract infections. A 13-year-old adolescent girl presented with pain, difficulty in micturition, and gross hematuria for almost two years before admission, and she had left flank pain since one year ago and significant loss of body weight during the illness. The close TB contact was her grandmother who was on TB treatment. Acid-fast bacilli yielded positive result, Mantoux test was positive (17 mm), urine GeneXpert MTB/Rif was positive; tuberculoma was identified on kidney histopathology, and a diuretic renogram revealed an uncorrected glomerular filtration rate (GFR) of the right and left kidney to be 32.5 mL/min/1.73 m2 and 5 mL/min/1.73 m2, respectively. During the treatment, oral anti-TB drug-induced hepatotoxicity (ADIH) occurred to the patient. This problem was solved with management according to the British Thoracic Society (BTS) guidelines. Screening TB in children is very important for a better outcome. If children complain of some complicated urinary tract infection, TB should be suspected. Optimaly treating children with urinary tract TB exagerrated with ADIH and CKD is very challenging.

Hemangioendothelioma of the Bladder: The Youngest Case Report in A Child.

Hemangioendothelioma is a vascular tumor that commonly found in soft tissue, lungs, heart, liver, and bones, but it is very rare in bladder. We report a case of pediatric hemangioendothelioma of the bladder in a 2 years 7 months-old boy that treated with total excision of the bladder and bilateral ureterocutaneoustomy. This case is the second case in pediatric patients, and the youngest case that reported in a child. Our patient is doing well post operatively. But unfortunately interferon a-2b is not available in our hospital. At 3 months follow up, there was progressive progression of the tumor. Recurrent Abdominal mass was confirmed by Abdominal CT-Scan. The patient was died one week later. Interferon a-2b is might be an effective regimen on this tumor but further study is needed to confirm this statement.
