Nakon transplantacije bubrega u velikog broja bolesnika dolazi do značajnog porasta tjelesne mase. Pandemija COVID-19 koja se javila kod nas početkom 2020. godine promijenila je dotadašnji način života i navike svih stanovnika uključujući i bolesnike s transplantatom. Cilj rada bio je ispitati kretanje tjelesne mase (TM) u bolesnika sa stabilnom funkcijom bubrežnog transplantata. Istraživanje je bilo retrospektivno. U ispitivanje je bilo uključeno 35 bolesnika (19 muškaraca, 16 žena). Prosječna životna dob na početku praćenja bila je 60,7 ± 11,5 godina, a prosječno vrijeme proteklo od transplantacije bubrega 9,3 ± 7,1 godina. Podatci su se analizirali u razdoblju od 18 mjeseci, od početka pandremije COVID-19 (od siječnja 2020. do 30. 06. 2021.) Referentno razdoblje od 18 mjeseci podijeljeno je u tri intervala u trajanju od 6 mjeseci. Analizirani podatci sakupljeni su na početku te nakon šest, 12 i 18 mjeseci. U svih ispitanika pratili smo: TM, izračunali indeks tjelesne mase (ITM), laboratorijske parametre i krvni tlak (KT). Od laboratorijskih parametara pratili smo: ureju, kreatinin, kolesterol i trigliceride. Uz to pratila se antihipertenzivna terapija i terapija hipolipemicima. Svi ispitanici u imunosupresivnom protokolu imali su kortikosteroide, a 91,4 % ispitanika bilo je na trojnoj imunosupresivnoj terapiji. Tijekom ispitivanog razdoblja došlo je do značajnog porasta TM i ITM ((P=0,007; P=0,03). U žena tijekom ispitivanog razdoblja nije bilo statistički značajnog porasta TM u odnosu na početnu vrijednost nakon šest, 12 i 18 mjeseci. U muškaraca je došlo do značajnog porasta TM nakon 12 i 18 mjeseci od ispitivanog razdoblja (P=0,01; P=0,04). Nije bilo statistički značajnih promjena u vrijednostima serumske ureje, kreatinina, kolesterola i triglicerida. Nije bilo statističke značajne razlike u prosječnim vrijednostima sistoličkog i dijastoličkog KT. Na početku istraživanja prosječan broj antihipertenziva po bolesniku je bio 2,17, a nakon 18 mjeseci trajanja pandemije prosječan broj antihipertenziva je narastao na 2,54; radilo s o statistički značajnoj razlici (P=0,002). Analizom prema spolu, u muškarca i u žena broj antihipertenziva u terapiji tijekom ispitivanog razdoblja se statistički značajno povećao (P=0,01; P=0,04). Nije bilo značajne razlike u uzimanju hipolipemika. Dobiveni rezultati pokazuju da je promjena životnih navika u bolesnika sa stabilnom funkcijom bubrežnog transplantata zbog pandemije COVID-19 uzrokovala porast TM uz značajno povećanje uzimanja antihipertenzivne terapije., After kidney transplant, a large number of patients gain weight. The COVID-19 pandemic, which occurred in our country in early 2020, changed the way of life and habits of all residents, including transplant patients. The aim of this study was to examine body mass (BM) patterns in patients with stable renal transplant function. The study was retrospective and included 35 patients (19 male and 16 female), mean age 60.7±11.5 years and mean time elapsed from kidney transplantation 9.3±7.1 years. Data were analyzed for 18-month period, from the beginning of the COVID-19 pandemic (from January 2020 to June 30, 2021). The reference period of 18 months was divided into three intervals of 6 months, and the data used were taken at the beginning and after 6, 12 and 18 months. In all subjects, we monitored BM, calculated body mass index (BMI), laboratory parameters and blood pressure (BP). Laboratory data included urea, creatinine, cholesterol and triglycerides. In addition, antihypertensive therapy and hypolipidemic therapy were followed. All subjects had corticosteroids in the immunosuppressive protocol, and 91.4% of them were on triple immunosuppressive therapy. There was a signifi cant increase in BM and BMI (p=0.007 and p=0.03, respectively) during the study period. There was no statistically signifi cant increase in BM compared to baseline BM in females. In men, there was a signifi cant increase in BM after 12 and 18 months (p=0.01 and p=0.04, respectively). There were no statistically signifi cant differences in serum urea, creatinine, cholesterol, and triglyceride levels during the follow-up period. There was no statistically signifi cant difference in the mean systolic and diastolic BP values. At the beginning of the study, the mean number of antihypertensives per patient was 2.17 and after 18 months of the pandemic the mean number of antihypertensives increased to 2.54, yielding a statistically signifi cant difference (p=0.002). The number of antihypertensives in therapy increased statistically signifi cantly during the study period in males and females (p=0.01 and p=0.04, respectively). There was no signifi cant difference in the use of hypolipidemic therapy. The results obtained show that the change in life habits due to the COVID-19 pandemic in patients with stable kidney transplant function caused an increase in BM and signifi cantly increased the use of antihypertensive therapy.
