"ABSTRAKLatar Belakang: Influenza masih merupakan ancaman infeksi serius di dunia terutama pada populasi usia lanjut. Meskipun kejadian influenza dapat ditekan dengan pemberian vaksinasi, namun efikasi vaksin influenza masih diragukan pada usia lanjut, terutama individu yang frail. Hal ini dikarenakan immunosenescence yang menyebabkan sistem imun kurang mampu mengatasi stres berupa infeksi termasuk memberikan respon yang adekuat terhadap pemberian vaksin.Tujuan: Mengetahui hubungan status frailty dengan respon imun pasca vaksinasi influenza pada populasi usia lanjutMetode: Studi kohort retrospektif ini mengambil data dari penelitian induk dengan subjek usia lanjut berusia 60 tahun keatas yang tergabung dalam Posyandu Lansia di 4 kelurahan di Kecamatan Pulo Gadung, Jakarta Timur. Status frailty ditentukan berdasarkan kuisoner Frailty Index 40 Items FI-40 . Vaksin Influenza yang dievaluasi adalah vaksin influenza trivalen inaktif. Serokonversi didefinisikan sebagai peningkatan titer inhibisi hemagglutinin sebanyak 4x lipat. Seroproteksi didefinisikan sebagai titer inhibisi hemagglutinin ge; 1:40.Hasil: Terdapat 140 subjek penelitian. Tingkat serokonversi vaksin influenza pada kelompok frail, pre-frail, dan sehat adalah 37,9 , 39 , 60 . Tingkat seroproteksi vaksin influenza pada kelompok frail, pre-frail dan sehat adalah 80 , 92,2 , 94,8 . Risiko relatif RR kelompok pre-frail/frail untuk kejadian tidak serokonversi adalah 0,93 IK 95 0,72-1,02 , dan RR untuk kejadian tidak seroproteksi adalah 1,7x IK 95 0,5-6,2 .Kesimpulan: Tidak ditemukan hubungan bermakna secara statistik antara status frailty dengan serokonversi dan seroproteksi vaksin influenza pada populasi usia lanjut.

ABSTRACT Background Influenza still become serious illness in this world especially in elderly population. Despite the prevalence of this disease has been decreased by vaccination, the efficacy of the vaccine still doubt full in frail elderly people. Immunosenescence is the underlying process in immune defect and cause the immune system become less capable to cope the stress like an infection, and also give an adequate response to vaccination.Objective To determine association between frailty status and immune response after influenza vaccination in elderly.Method This Retrospective cohort study was conducted using secondary data from the parent study of elderly subjects age ge 60 years who live in the community of Posyandu lansia in Pulo Gadung Region, East Jakarta. Frailty status was stated by Frailty Index 40 Items FI 40 . The influenza vaccine evaluated was the Trivalent Inactivated Vaccine. Seroconversion defined as four fold increase hemagglutinin inhibition titre. Seroprotection defined as Hemagglutinin Inhibition titer ge 1 40.Result There are 140 subject included in this study. Seroconversion influenza vaccine rate in frail, pre frail, and robust group are 37,9 , 39 , 60 . Seroprotection rate in frail, pre frail, and robust group are 80 , 92,2 , 94,8 . Relative Risk RR pre frail frail group for not seroconverted is 0,93 CI 95 0,72 1,02 , and RR for not seroprotected is 1,7 CI 95 0,5 6,2 .Conclussions There is no statistically significant association between frailty status and seroconversion nor seroprotection of influenza vaccine.

"Prevalensi pre-frail tinggi pada usia lanjut dan kondisi tersebut dapat berubah menjadi frail. Kolekalsiferol diduga memiliki potensi untuk memperbaiki sindrom frailty pada usia lanjut. Penelitian ini bertujuan mengkaji pengaruh kolekalsiferol terhadap kekuatan genggam tangan, kecepatan berjalan serta reseptor vitamin D (vitamin D receptor/VDR), interleukin-6 (IL-6), dan insulin-like growth factor-1 (IGF-1) monosit pada usia lanjut dengan pre-frail. Uji klinis acak tersamar ganda dilakukan di Poliklinik Geriatri RSCM pada bulan April–Desember 2021. Sebanyak 120 subjek dirandomisasi menjadi kelompok yang mendapat kolekalsiferol 4.000 IU/hari (60 subjek) serta kelompok yang mendapat plasebo/hari (60 subjek). Seluruh subjek mendapat suplementasi kalsium laktat 500 mg /hari. Pengamatan dilakukan selama 12 minggu. Terdapat 57 subjek pada kelompok kolekalsiferol dan 56 subjek pada kelompok plasebo yang menjalani penelitian hingga selesai. Analisis intention to treat dilakukan untuk mengevaluasi luaran kekuatan genggam tangan dan kecepatan berjalan, sedangkan analisis per protokol untuk mengevaluasi VDR, IL-6 dan IGF-1 monosit. Pada akhir pengamatan, tidak terdapat perbedaan bermakna pada kekuatan genggam tangan (p = 0,228), kecepatan berjalan (p = 0,734), VDR monosit (p = 0,45), IL-6 monosit (p = 0,57) dan IGF-1 monosit (p = 0,72) antara kedua kelompok perlakuan. Tidak ada korelasi antara perubahan VDR, IL-6 dan IGF-1 monosit dengan kekuatan genggam tangan dan kecepatan berjalan. Terdapat peningkatan kadar 25(OH)D yang bermakna pada masing-masing kelompok perlakuan dan peningkatan bermakna pada kelompok kolekalsiferol dibandingkan plasebo. Pemberian kolekalsiferol 4.000 IU pada usia lanjut pre-frail 12 minggu meningkatkan kadar 25(OH)D secara bermakna, namun belum terbukti dapat memperbaiki kekuatan genggam tangan, kecepatan berjalan, meningkatkan VDR dan IGF-1 monosit serta menurunkan IL-6 monosit. Fungsi ginjal memiliki pengaruh terhadap efek kolekalsiferol pada IGF-1 monosit. Kolekalsiferol meningkatkan jumlah monosit dengan IGF-1+ pada eGFR > 90, namun tidak pada eGFR 30–59.

Pre-frail prevalence is higher in the elderly. Frailty status is a dynamic condition. Pre-frail can fall into a frail condition. Cholecalciferol is regarded to have potential effect to improve frailty syndrome in the elderly. This study aimed to determine the effect of cholecalciferol on hand grip strength, walking speed, vitamin D receptors, IL-6, and IGF-1 monocyte in pre-frail elderly. A randomized double-blind clinical trial study at the RSCM Geriatric Polyclinic was conducted from April to December 2021. A total of 120 subjects were randomized into groups receiving 4000 IU cholecalciferol/day (60 subjects) and groups receiving placebo/day (60 subjects). All subjects received calcium lactate supplementation 500 mg/day. Observations were made for 12 weeks. There were 57 subjects in the cholecalciferol group and 56 subjects in the placebo group who completed the study. An intention to treat analysis was performed to evaluate the output of hand grip strength and walking speed, while a per protocol analysis was performed to evaluate monocyte VDR, IL-6 and IGF-1.There were no significant differences in hand grip strength (p = 0,228), walking speed (p = 0,734), VDR monocyte (p = 0,45), IL-6 monocyte (p = 0,57) and IGF-1 monocyte (p = 0,72) between treatment groups. There were no correlation between changes in the VDR, IL-6 and IGF-1 monocytes with changes in hand grip strength and walking speed. There was a significant increase in 25(OH)D levels in each group and a significant difference between groups. Supplementation of cholecalciferol 4.000 IU daily for 12 weeks increased serum 25(OH)D level significantly, however it did not improve hand grip strength and walking speed, and did not affect VDR, IL-6 and IGF-1 monocytes in pre-frail elderly. Kidney function had an influence on the effect of cholecalciferol on monocyte IGF-1. Cholecalciferol increased the number of monocytes with IGF-1+ at eGFR > 90, but not at eGFR 30–59."

ABSTRACT

Metformin is considered to have potential effects to improve frailty syndrome by modifying insulin resistance, inflammation, and myostatin serum level.

This study aimed at investigating the effect of metformin on handgrip strength, gait speed, myostatin serum level, and health related quality of life HR QoL in pre frail elderly.

A double blind randomized controlled trial was conducted on elderly outpatients aged 60 years and older with pre frail status consecutively recruited from March 2015 to June 2016 at Cipto Mangunkusumo Hospital. Patients with history of diabetes mellitus, Geriatric Depression Scale score ge 10, Abbreviated Mental Test score 8, acute phase of diseases, and contraindication s to metformin were excluded. The measurement of study outcomes was conducted at baseline and after 16 weeks of intervention.

One hundred twenty subjects were randomized and equally assigned into metformin 3 x 500 mg or placebo group. There were 43 subjects in metformin group and 48 subjects in placebo group completed the intervention. The mean gait speed in metformin group significantly improved by 0.39 0.77 second or 0.13 0.24 meter second, even after adjusted for importance prognostic factors p 0,024 . Intention to treat analysis on the presence or absence of increased gait speed 0.1 meter second showed ARR 8.3 95 CI 7.9 ndash 24 , with NNT of 12. There were no significant differences on handgrip strength, myostatin serum level, and HR QoL between the two intervention groups. Myostatin serum level had weak negative correlation with gait speed r 0.247 p 0.018 , but did not correlate with handgrip strength. EQ 5D index had moderate positive correlation with gait speed r 0.566 p 0.000 and weak positive correlation with handgrip strength r 0.355 p 0.001.

In conclusion, metformin 3 x 500 mg for 16 weeks significantly improved gait speed as one of the HR QoL dimensions, but not significantly improved the EQ 5D index score and handgrip strength nor decreased myostatin serum level.

Keywords. gait speed, handgrip strength, health related quality of life, metformin, myostatin, pre frail, elderly."

"Background: sarcopenia contributes to the development of frailty syndrome. Frailty syndrome is potentially improved by modifying insulin resistance, inflammation, and myostatin level. This study is aimed to investigate the effect of metformin on handgrip strength, gait speed, myostatin serum level, and health related quality of life (HR-QoL) among non diabetic pre frail elderly patients.Methods: a double blind randomized controlled trial study was conducted on non-diabetic elderly outpatients aged >60 years with pre frail status based on phenotype and/ or index criteria (Cardiovascular Health Study and/ or Frailty Index 40 items) consecutively recruited from March 2015 to June 2016 at Cipto Mangunkusumo Hospital. One hundred twenty subjects who met the research criteria were randomized and equally assigned into 3 x 500 mg metformin or placebo group. The study outcomes were measured at baseline and after 16 weeks of intervention.Results: out of 120 subjects, 43 subjects in metformin group and 48 subjects in placebo group who completed the intervention. There was a significant improvement on the mean gait speed of metformin group by 0.39 (0.77) second or 0.13 (0.24) meter/second that remained significant after adjusting for important prognostic factors (p = 0.024). There was no significant difference on handgrip strength, myostatin serum level, and HR QoL between both groups.Conclusion: 3 x 500 mg metformin for 16 weeks was statistically significant and clinically important in improving usual gait speed as one of the HR QoL dimensions, but did not significantly improve the EQ 5D index score, handgrip strength, nor myostatin serum level."
