Background: Cancer is still one of the major health problems in the world. The incidence of gynecological cancer in Indonesia is still high. Nutritional aspect is one of the most frequent aspects of abnormalities in patients with cancer. Patient Generated-Subjective Global Assessment (PG-SGA) is a nutritional screening modality that combines qualitative and semi-quantitative data. Systemic inflammatory process that occurs in cancer patients can result in a decrease in albumin and prealbumin levels. However, there have not been many previous studies looking at the correlation between albumin and prealbumin levels on the PG-SGA score.

Objective: Knowing the best parameters in detecting malnutrition for gynecological oncology patients at RSUPN Dr. Cipto Mangunkusumo.

Methods: This study used a cross-sectional method. The subjects of this study were diagnosed with gynecological cancer who went to the Gynecological Oncology Polyclinic of RSUPN Dr. Dr. Cipto Mangunkusumo and planned or already undergoing therapy during October 2020 - September 2021. Patients with a history of primary malignancy other than gynecological malignancy, receiving oral or intravenous corticosteroid therapy, history of gastrointestinal surgery affecting nutrient absorption/intake, and history of acute or chronic liver disease and alcoholism was excluded from the study.

Results: There were 90 subjects who were included in this study. Overall, the average level of albumin was 4.19 g/dL, the average level of prealbumin was 39.1 mg/dL, and the average of scored-PG-SGA was 3 or category A. There was a weak positive correlation between albumin and prealbumin levels (r=0.378, p=0.000). This study showed a weak negative correlation between albumin level and scored-PG-SGA (r=-0.313, p=0.003), whereas there was no correlation between prealbumin levels and scored-PG-SGA (r=-0.145, p=0.173).

Conclusion: A weak negative correlation was found between albumin and the scored-PG-SGA, but no correlation was found between prealbumin and the scored-PG-SGA."

Background. Critically ill patients are in catabolic conditions that have imbalances in protein synthesis and breakdown. Thus, they require adequate protein intake to maintain the muscle mass and to increase the prealbumin levels and nitrogen balance. Ophiocephalus striatus (OS) is a potential source of proteins since it contains high amount of amino acids, fatty acids, minerals, and vitamins. This study was aimed to measure the effect of OS extract supplementation on cross-sectional area (CSA) of rectus femoris and biceps brachii, prealbumin levels, and nitrogen balance in critically ill patients with ventilator.

Methods. This was a randomized controlled clinical trial study involving patients aged 18-65 years old with ventilator in intensive care unit (ICU) Dr. Cipto Mangunkusumo Hospital between July until October 2019. In total, 42 subjects were randomized into two groups. Extract group (n=19) recieved 15 g of OS extract supplementation daily, administered from the second day to the sixth day. Control group (n=23) did not receive the extract. Measurement of CSA of rectus femoris and biceps brachii, prealbumin levels, and nitrogen balance were done in the first and the seventh day.

Results. There was an increase of cross sectional area of rectus femoris in extract group (p=0.038) and a decrease in control group (p=0.006) with significant difference between the two groups (p=0.001). There was an increase of cross sectional area of biceps brachii in extract group (p=0.033) and a decrase in control group (p=0.001) with significant difference between the two groups (p<0.001). There was an increase of prealbumin levels in both groups, extract group (p<0.001) and control group (p=0.023), with a significant difference of increase between the two groups (p<0.001). There was an increase of nitrogen balance in both groups, extract group (p<0.001) and control group (p<0.001), with an insignificant difference of increase between the two groups (p<0.685)

Conclusion. Administration of Ophiocephalus striatus extract supplementation can significantly increase the cross-sectional area of rectus femoris and biceps brachii, and the prealbumin levels in critically ill patients."

"Penyakit TB MDR merupakan salah satu penyakit infeksi yang prevalensinya semakin meningkat dari tahun ke tahun di Indonesia dengan angka keberhasilan pengobatan 45%. Konversi kultur sputum merupakan suatu prediktor kuat dari awal keberhasilan terapi. Waktu konversi yang lambat akan memperpanjang periode penularan dan memprediksi tingkat kegagalan pengobatan yang tinggi. Terdapat beberapa faktor risiko yang berhubungan dengan konversi kultur sputum pasien TB MDR. Penelitian terkait faktor risiko kadar albumin dengan waktu konversi kultur sputum masih sangat terbatas. Tujuan penelitian ini adalah untuk mengetahui hubungan kadar albumin dengan waktu konversi kultur sputum di poli MDR terpadu RS Paru Dr M Goenawan Partowidigdo tahun 2022. Penelitian ini menggunakan studi cohort retrospektif dengan sampel yang diambil dari catatan rekam medis dan SITB pasien poli MDR. Variabel yang diteliti adalah kadar albumin < 3,5 gram/dl dan ≥ 3,5 gram/dl dengan variabel covariat usia, jenis kelamin, pendidikan, index masa tubuh, status merokok, gradasi sputum bta, komorbid, regimen pengobatan, dan kepatuhan minum obat . Hasil penelitian berdasarkan analisis multivariat menunjukkan kadar albumin < 3,5 mg/dl memiliki kecepatan waktu konversi 41,8% lebih lambat dengan (HR=0,582, 95% CI 0.344-0.984) untuk mengalami konversi dibanding dengan pasien TB MDR dengan kadar albumin ≥ 3,5 mg/dl setelah memperhitungkan status merokok dan kepatuhan minum obat. Perlunya memperbaiki kadar albumin yang rendah pada pasien TB MDR di rumah sakit dan memberikan penyuluhan kepada keluarga pasien agar turut berpartisipasi memantau asupan makan pasien yaitu makanan yang mengandung tinggi protein seperti ikan gabus serta ekstra putih telur untuk membantu meningkatkan kadar albumin pasien yang dapat berguna untuk terjadinya konversi kultur sputum.

MDR TB disease is an infectious disease whose prevalence is increasing from year to year in Indonesia with a treatment success rate of 45%. Sputum culture conversion is a strong predictor of initial therapeutic success. Slow conversion time will prolong the period of transmission and predict a high rate of treatment failure. There are several risk factors associated with sputum culture conversion in MDR TB patients. Research related to risk factors for albumin levels and sputum culture conversion time is still very limited. The aim of this study was to determine the relationship between albumin levels and sputum culture conversion time at the integrated MDR polyclinic at Dr M Goenawan Partowidigdo Pulmonary Hospital in 2022. This study used a retrospective cohort study with samples taken from medical records and SITB patients at poly MDR. The variables studied were albumin levels < 3.5 mg/dl and ≥ 3.5 mg/dl with the covariate variables age, sex, education, body mass index, smoking status, sputum gradation, co-morbidities, medication regimens, and drinking adherence drug . The results of the study based on multivariate analysis showed that albumin levels < 3.5 mg/dl had a 41.8% slower conversion time (HR=0.582, 95% CI 0.344-0.984) to experience conversion compared to MDR TB patients with albumin levels ≥ 3.5 mg/dl after taking into account smoking status and medication adherence. It is necessary to improve low albumin levels in MDR TB patients at the hospital and provide counseling to the patient's family to participate in monitoring the patient's food intake, namely foods that contain high protein such as snakehead fish and extra egg whites to help increase the patient's albumin levels which can be useful for the occurrence of sputum culture conversion."

"Kejadian infeksi dengue dewasa di Indonesia tergolong tinggi. Komplikasinya adalah sindrom renjatan dengue (SRD) akibat kebocoran plasma. Untuk mengatasi kebocoran plasma, WHO menganjurkan pemberian cairan kristaloid isotonik atau koloid seperti albumin 5%. Penelitian in vitro memperlihatkan ikatan albumin dengan reseptor glikoprotein 60 (gp60) di sel endotel menstimulasi ekspresi caveolin-1 dan Src protein tyrosine kinase (PTK) yang meningkatkan perpindahan albumin ke ekstravaskular, namun secara in vivo belum diketahui pengaruh cairan albumin terhadap proses transitosis dan caveolin-1 urin.Penelitian ini merupakan open label randomized controlled trial sejak bulan November 2018 sampai dengan Januari 2020, di beberapa rumah sakit di Jakarta dan Banten. Dari 90 pasien, sebanyak 30 pasien memenuhi kriteria DD, dan 60 pasien memenuhi kriteria DBD. Alokasi secara acak dilakukan pada 60 pasien DBD, yang terdiri atas kelompok demam berdarah dengue yang diberikan ringer laktat (n = 30) dan kelompok demam berdarah dengue yang diberikan albumin (n = 30).Pasien DBD yang diberikan albumin 5%, caveolin-1 plasma menurun pada jam ke-12 (p = 0,016); Src PTK lebih rendah pada jam ke-12 (p = 0,048); hemokonsentrasi lebih ringan pada jam ke-12 (p = 0,022) dan ke-24 (p = 0,001); kadar albumin serum lebih tinggi pada jam ke-12 (p = 0,037) dan ke-24 (p = 0,001); albumin urin lebih ringan pada jam ke-24 (p = 0,006) dan ke-48 (p = 0,005); dan lama rawat lebih pendek (p < 0,001) dibandingkan dengan ringer laktat.Kesimpulan: pemberian cairan albumin 5% memperbaiki kebocoran plasma transitosis dan memperpendek lama rawat pasien DBD.

The incidence of adult dengue infection in Indonesia is quite high. The complication is dengue shock syndrome (DSS) due to plasma leakage. To overcome plasma leakage, WHO recommends giving isotonic crystalloid solutions or colloids such as albumin 5%. In vitro studies have shown that albumin binding to the glycoprotein receptor 60 (gp60) in endothelial cells stimulates the expression of caveolin-1 and Src protein tyrosine kinase (PTK) which increases albumin transfer to the extravascular space, but in vivo the effect of albumin fluid on the process of transitosis and urine caveolin-1 is not known.

This study is an open label randomized controlled trial from November 2018 to January 2020, in several hospitals in Jakarta and Banten. From 90 patients, 30 patients met the criteria for DD, and 60 patients met the criteria for DHF. Random allocation was made to 60 DHF patients, consisting of the dengue hemorrhagic fever group given Ringer's lactate (n = 30) and the dengue hemorrhagic fever group given albumin (n = 30).

Patients who were given albumin 5%, caveolin-1 plasma decreased at 12th hours (p = 0.016); Src PTK was lower at 12 hours (p = 0.048); milder hemoconcentration at 12th (p = 0.022) and 24th (p = 0.001) hour; serum albumin levels were higher at 12th (p = 0.037) and 24 hours (p = 0.001); urinary albumin was milder at 24th (p = 0.006) and 48th (p = 0.005); and shorter length of stay (p < 0.001) compared to ringer lactate.

Conclusion: administration of albumin 5% fluid improves transcytosis plasma leakage and shortens the length of stay of dengue infection patients."

There was no statistically significant relationship between albumin and radiation response (p≥0.05). There was a statistically significant relationship between hypoxia and radiation response (p<0,05). There were no correlation between albumin and hypoxia (r=-0,24, p=0,324).

Conclusion: This study showed that there was no correlation between albumin preirradiation and response in locally advanced nasopharyngeal cancer. It was proven that hypoxia increased radioresistance in locally advanced nasopharyngeal cancer. There was no correlation between albumin preirradiation and hypoxia."

"Pajanan patogen melalui gastrointestinal pada daerah kumuh lebih tinggi dibanding nonkumuh. Hal tersebut mempengaruhi produksi protein globulin yang salah satunya berperan dalam sintesis IgA. Oleh karena itu, peneliti tertarik untuk mengetahui perbandingan kadar IgA pada daerah kumuh dan nonkumuh serta hubungannya dengan rasio albumin terhadap globulin. Pengukuran kadar IgA dilakukan menggunakan metode radial immunodiffusion test (RIDT), sedangkan data rasio albumin terhadap globulin didapatkan dari penelitian sebelumnya. RIDT bekerja dengan prinsip difusi radial sampel antibodi menjauhi sumur berbentuk silindris. Pada kit, terdapat anti terhadap antibodi spesifik yang akan diukur. Hasilnya berupa ikatan antibodi dengan anti-antibodi membentuk cincin dan diukur diameternya. Nilai IgA dikonversi ke dalam satuan mg/L. Hasil analisis kadar IgA menggunakan uji Mann-Whitney menemukan kadar IgA daerah kumuh lebih tinggi dibandingkan nonkumuh namun tidak bermakna secara statistik (p=0,620). Kadar IgA dan rasio albumin globulin ditransformasi menjadi variabel kategorik dan dikelompokkan menjadi 4 zona. Pada zona 3 dimana rasio albumin terhadap globulin tinggi dan kadar IgA rendah, proporsi subjek didominasi oleh penduduk daerah nonkumuh dibandingkan kumuh (47% vs. 14%). Hasil uji Chi Square menunjukkan perbedaan proporsi subjek tersebut bermakna secara statistik (p=0,041). Hubungan antara rasio albumin terhadap globulin dengan ekspresi IgA dianalisis menggunakan uji Pearson dan ditemukan adanya korelasi negatif yang bermakna secara statistik (r= -0,319 dan p= 0,048). Oleh karena itu, dapat disimpulkan tingginya tingkat pajanan patogen melalui gastrointestinal pada daerah kumuh menyebabkan produksi IgA sebagai respon imun mukosa lebih tinggi dibandingkan dengan nonkumuh. Sintesis IgA tersebut berhubungan dengan rasio albumin terhadap globulin karena globulin merupakan komponen penyusun IgA.Pathogenic exposure in slum is higher compared to nonslum area and mainly occurs through the gastrointestinal. It will affect the rate of globulin production which used as a component to synthesize immunoglobulin A (IgA) Therefore, author is interested to investigate comparison between IgA of people living in slum and non-slum area and the relation IgA expression with albumin globulin ratio. Measurement of the IgA was done using radial immunodiffusion test (RIDT), while the data of albumin globulin ratio was obtained from the previous research. Result of IgA analysis using Mann whitney test shows that IgA level of people living in slum area is higher than non-slum area but not statistically significant (p=0.620). Data of IgA level and albumin globulin ratio was transformed into categoric form and classified into four zones. Zone 3, where the IgA level is low and albumin globulin ratio is high, the subjects proportion found in this zone are dominated by people living in non-slum area (47% vs. 14%). This result is also supported by the Chi-square test that shows a significance difference between proportion of people living in slum and non-slum area found in the zone 3. Next, relation between albumin globulin ratio to the level of IgA was analyzed using Pearson test. The result shows that there is a significant negative correlation between albumin globulin ratio and IgA level (r= -0.319 dan p= 0.048). Therefore, it can be concluded that high level of pathogenic exposure through the gastrointestinal tract in slum area will lead to an increase of IgA production resulting higher level of IgA found in the serum. This IgA production on both populations has a relation with albumin globulin ratio since globulin is one of the constituent component of IgA."
