"Peningkatan kadar Neutrophil Gelatinase Associated Lipocalin (NGAL) dikaiktkan dengan asupan protein yang rendah pada pasien sakit kritis dewasa di ICU. Belum ada penelitian sebelumnya yang menilai hubungan tersebut. Studi ini bertujuan untuk mengetahui hubungan asupan protein dengan Neutrophil Gelatinase Associated Lipocalin (NGAL) pada pasien sakit kritis dewasa. Studi potong lintang ini dilakukan pada 40 pasien sakit kritis dewasa di ICU RS Universitas Indonesia. Subjek yang memenuhi kriteria inklusi dan eksklusi diambil darahnya untuk dilakukan pemeriksaan NGAL serta dinilai asupan proteinnya. Uji t tidak berpasangan dan uji korelasi Spearman digunakan dalam analisis data (p<0,05). Rentang asupan protein pada subjek penelitian ini adalah 13,5-110 g/hari, dengan rerata asupan protein dalam g/kgBB/hari adalah 0,82±0,29. Rentang kadar NGAL plasma pada subjek penelitian adalah 87,75-787,65 ng/mL. Tidak ditemukan adanya hubungan yang bermakna antara asupan protein dengan NGAL pada pasien sakit kritis dewasa. Hubungan bermakna didapatkan antara usia dan penyakit penyerta dengan NGAL pada pasien sakit kritis dewasa.

Elevated Neutrophil Gelatinase Associated Lipocalin (NGAL) levels are associated with low protein intake in adult critically ill patients in the ICU. No previous studies have evaluated this relationship. This study aimed to determine the association of protein intake with Neutrophil Gelatinase Associated Lipocalin (NGAL) in adult critically ill patients. This cross-sectional study was conducted on 40 adult critically ill patients in the ICU of Universitas Indonesia Hospital. Subjects who met the inclusion and exclusion criteria had their blood drawn for NGAL and protein intake assessed. Independent t-test and Spearman’s correlation test were used to examine the data (p<0.05). The range of protein intake in the subjects of this study was 13.5-110 g/day, with the mean protein intake in g/kgBB/day being 0.82±0.29. The range of plasma NGAL levels in the study subjects was 87.75-787.65 ng/mL. There was no significant association between protein intake and NGAL in adult critically ill patients. Significant association was found between age and comorbidities with NGAL in adult critically ill patients."

"Kemoterapi dengan cisplatin merupakan modalitas utama pada terapi pada kanker ovarium, walaupun telah diketahui toksisitasnya pada berbagai organ termasuk ginjal. Kurkumin, senyawa fenolik yang diperoleh dari Curcuma longa, diketahui memiliki efek proteksi pada ginjal akibat cisplatin pada berbagai model toksisitas in vivo. Namun, efek kurkumin pada ginjal dibatasi oleh bioavailabilitasnya yang rendah. Kelompok penelitian kami telah berhasil mengembangkan formulasi kurkumin nanopartikel baru yang telah terbukti memperbaiki efikasi cisplatin pada model kanker ovarium. Namun, belum diketahui apakah formulasi kurkumin nanopartikel ini juga dapat memperbaiki fungsi dan kondisi inflamasi pada ginjal yang disebabkan oleh cisplatin.Metode Sebanyak 24 ekor tikus Wistar betina dibagi menjadi: 6 ekor tikus normal (sham treatment) dan 18 ekor tikus yang diinduksi menjadi kanker ovarium dengan DMBA. Tikus kanker ovarium dibagi menjadi 3 kelompok masing-masing 6 ekor yang menerima cisplatin 4 mg/kgBB/minggu atau cisplatin 4 mg/kgBB/minggu +kurkumin 100 mg/kgBB/hari atau cisplatin 4 mg/kgBB/minggu + nanokurkumin 100 mg/kgBB/hari. Terapi diberikan selama 4 minggu, kemudian dilakukan terminasi dan diambil darah dan organ ginjal untuk analisis penanda fungsi ginjal dan inflamasi.Hasil Nanokurkumin dapat menurunkan kadar ureum serum signifikan dibandingkan kelompok cisplatin, namun tidak mempengaruhi kadar kreatinin dan sedikit menurunkan kadar neutrophil gelatinase-associated lipocalin (NGAL). Nanokurkumin tidak berhasil menurunkan kadar penanda inflamasi: TNF-, IL-1β dan IL-6.KesimpulanNanokurkumin memiliki kecenderungan untuk memperbaiki beberapa penanda fungsi ginjal dalam darah pada model kanker ovarium yang diberikan cisplatin, namun tidak mempengaruhi kadar penanda inflamasi di ginjal.

The effects of nanocurcumin on kidney function and inflammatory

markers in rat model of ovarian cancer treated with cisplatin

Cisplatin remains the main modality of treatment for ovarian cancer, despite its known toxic effects to various organs, including the kidney. Curcumin, a phenolic compound derived from Curcuma longa, was known to have a renoprotective effect on cisplatin- induced in vivo models. However, the beneficial effect of curcumin on the kidney is limited by its low bioavailability. Our research group has successfully developed a novel curcumin nanoparticle formulation that has been shown to improve the efficacy of cisplatin in ovarian cancer models. However, it is not yet known whether this curcumin nanoparticle formulation can also improve kidney function and inflammatory conditions caused by cisplatin in ovarian cancer models.

Method

A total of 24 female Wistar rats were divided into: 6 normal rats (sham treatment) and 18 rats induced to develop ovarian cancer with DMBA. Ovarian cancer rats were divided into 3 groups of 6 each receiving cisplatin 4 mg/kgBW/week or cisplatin 4 mg/kgBW/week + curcumin 100 mg/kgBW/day or cisplatin 4 mg/kgBW/week + nanocurcumin 100 mg/day. kgBB/day. Therapy was given for 4 weeks, then terminated and blood and kidney were taken for analysis of markers of kidney function and inflammation.

Results

Nanocurcumin lowered serum urea levels significantly compared to the cisplatin group. However, nanocurcumin did not alter creatinine levels and slightly reduced serum neutrophil gelatinase-associated lipocalin (NGAL) concentrations. Nanocurcumin was did not affect the inflammatory markers studied: TNF-, IL-1β and IL-6.

Conclusion

Nanocurcumin has a tendency to improve several markers of kidney function in cisplatin- treated ovarian cancer models. However, the effect was not associated by the alteration of inflammatory cytokines in the kidney."

"Background: living kidney donation is a safe medical procedure. Kidney function after donation is crucial for donors’ health and quality of life. Kidney hyperfiltration is a compensatory mechanism, which will preserve kidney function after unilateral nephrectomy. The number of studies regarding hyperfiltration in living kidney donors is limited. Our study aimed to explain kidney hyperfiltration mechanism and evaluate its effect on the kidney function within 30 days after surgery. Methods: our study was a prospective cohort study with 46 living-kidney donors participating in the study between April and December 2019. We evaluated main outcomes, the 30-day post-surgery kidney function, which was evaluated by calculating estimated glomerular filtration rate (eGFR) and Urinary Albumin to Creatinine Ratio (ACR). The subjects were categorized into two groups based on their 30-day outcomes, which were the adaptive (eGFR > 60 mL/min/1.73 m2 and/or ACR > 30 mg/g) and maladaptive (eGFR < 60 mL/min/1.73 m2 and/or ACR > 30 mg/g) groups. A series of evaluation including calculating the renal arterial resistive index (RI) and measuring urinary vascular endothelial growth factor (VEGF), neutrophil gelatinase-associated lipocalin (NGAL), and heparan sulfate (HS) levels were performed before surgery and serially until 30 days after surgery. Multivariate analysis with adjustments for confounding factors was done. Results: forty donors were included and mostly were female (67.5%). The average age and body mass index (BMI) were 45.85 (SD 9.74) years old and 24.36 (SD 3.73) kg/m2 , respectively. Nineteen donors (47.5%) had maladaptive hyperfiltration outcomes. The hyperfiltration process was demonstrated by significant changes in renal arterial RI, urinary VEGF, NGAL, and HS levels (p<0.005). There was no significant difference regarding RI, urinary VEGF, NGAL, and HS levels between both groups. Several confounding factors (BMI over 25 kg/m2 , familial relationship, age over 40 years old, and arterial stiffness) were significantly influenced by kidney hyperfiltration and outcomes (p<0.05). Conclusion: the hyperfiltration process does not affect the 30-day post-nephrectomy kidney function of the donors. Several other factors may influence the hyperfiltration process and kidney function. Further study is necessary to evaluate kidney function and its other related variables with a longer period of time study duration."
