Background
Sleeping problems are common in hemodialysis (HD) patients. The aim of this study was to determine sleep quality (SQ) in HD patients and to evaluate its relationship with patient’s quality ...of life (QoL), sociodemographic and laboratory data.
Methods
Two hundred HD patients from the Hemodialysis Clinic, Bosnia and Herzegovina, were enrolled in the study. There were 122 men and 78 women with a mean age of 56.8 ± 14.3 (range 20–85) years and a mean HD duration of 62.6 ± 57.0 months. We used the Pittsburgh Sleep Quality Index (PSQI) and the Health Survey for Dialysis Patients (SF-36).
Results
Seventy-three percent of patients showed a poor SQ response. The average sleep latency of patients was 48.2 min, and the average sleep duration was 4.9 h. Ninety-eight percent of patients experienced some sort of sleep disturbances on weekly basis. The most common sleep disturbances were insomnia (84.5%), day and night sleep reversal (39.0%), excessive daytime sleepiness (EDS) (34.0%), nightmares (25%) and restless legs syndrome (RLS) (20.5%). The most frequent causes of sleep disorders were snoring (47%), pain (35%), daytime napping (34%), breathing problems (30%) and pruritus (28%). Ninety-three percent of patients experienced daytime dysfunction and 46.5% of them were taking sleep medications. Younger patients, employed patients and patients in 3rd HD shift showed significantly better SQ compared to the others. Compared with good sleepers, poor sleepers were more frequently on conventional HD and had higher serum phosphate and PTH and significantly lower Hb.
Conclusion
The poor SQ in our HD population significantly correlated with their QoL.
Patients with end stage renal disease (ESRD) have a reduced response to vaccination against hepatitis B infection. The aim of the study has been to determine the adequacy of immune response with new ...protocol of vaccination against hepatitis B infection.
The study included incident hemodialysis patients since 2008 until 2011 at the Clinic of Hemodialysis of the Clinical Center of the University of Sarajevo. We started the new vaccination protocol in September 2009. New protocol implied vaccination six month before starting renal replacement therapy (RRT) and "ic" (intracutaneously) application vaccine vs. "sc" (subcutaneously) application. Vaccination was carried out for over 12 months. The follow up period lasted from 2009 to 2011.
The study included 64 patients, men were represented with 57,81% (37), and 42,19% women (27), who were divided in two groups. The first group included patients from the period from 2008 to 2009, who have been vaccinated under the old vaccination protocol, while the second group included patients with the new protocol from September 2009 to 2011. The first group had 28 patients, mean age of patients was 55,17 +/- 11.84 and mean duration of hemodialysis was 24,65 +/- 5,32 months. The second group had 36 patients, mean age of patients was 62,79 +/- 15,88 years, and mean duration of hemodialysis was 22,16 +/- 24,53 month. Neither group of patient has been previously vaccinated, nor these had positive in serum antiHBs before vaccination in second group. Five patients received a booster dose of vaccine, after which 4 showed adequate responses to anti HbS. In the first group of patients, out of total of 28 patients, 15 patients did not respond response with the adequate anti-HbS titer at the end of vaccination. In the second group of patients, out of 36 patients 31 of them responded to the vaccination with the new protocol, which was statistically significant (p<0,005). The total percentage of patients with adequate titer of antiHBs after vaccination towards a new protocol was 97.43% and the percentage of patients who required booster dose of vaccines was 12.82%.
Vaccination of patients in ESRD,six months before renal replacement therapy and intradermal application of vaccine vs. subcutaneously, improved immune response of our patients.
Patients with chronic renal failure treated with hemodialysis represent a high risk group for the development of tuberculosis (TB) in comparison to general population.
The aim of the study was to ...evaluate clinical presentation, biochemical parameters and outcome of tuberculosis in patients attending the Center for Hemodialysis, Sarajevo University Clinical Center.
The study conducted during the 2000-2005 period included four patients with tuberculosis that were already treated with chronic hemodialysis. Three of these four patients had pulmonary type and one had extrapulmonary type (bone type) of tuberculosis diagnosed by bone biopsy. Miliary TB diagnosis was verified with radiographic lung imaging and appropriate bacteriologic and biochemistry tests.
The mean age of the study patients was 66.5 +/- 59.6 years and mean hemodialysis duration 6.7 +/- 4.5 years. During the study period, we diagnosed four cases of active tuberculosis in 200 patients receiving hemodialysis therapy (2%). Tuberculin test was performed in all four patients and was negative. Clinical presentation was predominated by inappetence, feebleness and elevated body temperature. Biochemical tests revealed anemia (Htc 0.25 +/- 0.15), hypoalbuminemia (36.0 +/- 28.5) and extremely raised sedimentation raste (86 +/- 30). Increased transaminases were present in two of four patients; the culture of Mycobacterium tuberculosis was found in patients with pulmonary type of TB. Radiographic tests revealed miliary changes in two patients and pleural effusion in one patient. All patients were administered tuberculostatic drugs and six-month treatment resulted in full recovery.
Negative PPD test does not exclude the occurrence of TB in hemodialysis patients and the existence of pulmonary infiltrate and pleural effusion on radiographic chest images suggests the presence of the TB.
Recent studies show that psychological status of HD patients has been changed in terms of an increased score of the called neurotic triad: hypochondria, depression and hysteria. The aim of this study ...was to evaluate the correlation between the development of psychopathological tendencies in HD patients and the demographic features such as: gender, age, marital status, education level, employment status and HD duration.
There were 56 patients on HD. Depending on registered psychopathological tendencies, we compared patients according to the mentioned demographical characteristics. We applied MMPI 201. Previously, all patients were psychologically examined by explorative interview regarding demographical data and the pre-dialysis psychological status. To compare categorical variations, we use 6 multivariant analysis of variance. A p value of <0.5 was considered to be statistically significant.
The overall profile of psychopathological tendencies of HD patients indicates increase of scores on neurotic triad. Female patients showed significantly higher level of psychosteny than male patients (FPt=4.86, p<0.05): singles showed significantly higher scores on some psychotic subscales--paranoia, schizophrenia, mania--in relation to the group of married patients (FPa=7.21, FSc=6.84, FMa=5.35, p<0.05): patients with only primary school have significantly more expressive paranoia in relation to patients with university education (FPa=3.80, p<0.05); unemployed patients have significantly more expressed paranoia and tendencies to emphasize pathology in relation to employed patients (FF=5.13, FPa=5.94, p<0.05).
Depression could be taken as a a primary psychiatric complication associated with life on haemodialysis. Gender, marital status, education level and employment status significantly influence the differences in occurrences of psychopathological tendencies in HD patients.
The prevalence of MRSA (Methicillin Resistant Staphylococcus Aureus) in haemodialysis patients has increased dramatically during recent years. The aim of our study is to determine the prevalence of ...MRSA colonization among haemodialysis patients and medical staff.
This prospective study included 235 patients undergoing haemodialysis therapy and 60 medical staff members, in the Center for Haemodialysis Sarajevo. Nasal and throat samples were taken (identification of MRSA was performed using standard microbiological methods). A total of 474 nasal and throat cultures from patients' samples and 120 cultures from medical staff samples were obtained.
The total number of sampled patients was 235 and colonies were found in 36 of the samples (15.3%). Among medical staff nasal carriage rate of MRSA was 11.6% (7/60). The mean age of haemodialysis patients with MRSA was 52.94:1:5.3. The patients aged between 55 and 64 had the highest prevalence of MRSA (11/36, 30.55%). Those aged 45-54 had the next highest prevalence of nasal carriage (10/36, 27.77%). Patients aged 65 years had middle prevalence of MRSA (6/36, 8.33%). Patients aged 25-34 had the lowest prevalence of nasal carriage. We did not have possibilities to isolate MRSA positive dialysis patients, and we used intensive antibacterial prophylaxis. We treated our patients with mupirocin ointment (three times a day for 5-14 days) and gained decolonization in 34 patients (94.4%). In the treatment period, positive medical staff did not come to work.
The overall prevalence of MRSA colonization in our dialysis patients was higher (15.3%). Implementation of adequate strategies for prevention of MRSA with application of mupirocin among carriers, reduced prevalence of MRSA in our dialysis units.
Chronic renal failure is associated with endocrine abnormalities, which in some cases cause polyendocrinopathy responsible for the symptoms and complications. The consequence of secondary ...hyperparathyroidism is not only bone disease but may be cardiovascular disorders, peripheral nerve damage and impact on the level of sex hormones.
To evaluate the interactions between parathyroid hormone and sexual hormones and the effect of elevated levels of parathyroid hormone secretion on various sexual hormones. The study included 72 patients who were undergoing chronic hemodialysis program 3 times a week at the clinic for hemodialysis. Patients were divided into two groups according to parathyroid hormone values and child-bearing age. The study is a retrospective-prospective and lasted for 1 year. At the beginning, after 6 months, and at the end of the study were determined the PTH, FSH, LH, progesterone, testosterone, beta-estradiol, prolactin.
During the study period followed are the values of sexual hormones and PTH in 72 patients of which 41 men and 31 women. Of these 33.3% (24) men were in the reproductive age, and 23.6% (17) were women in the reproductive age. The mean age of patients was 53.2 +/- 12.16, and the average duration of hemodialysis was 7.57 +/- 4.0. PTH showed a slight tendency to increase 274.45 +/- 220.74 pg/dL at baseline, at the end of study 383 +/- 313.2 also increased during the study was recorded and the values progesterone. Statistically significant effect of PTH showed the FSH p < 0.01 LH p < 0.05 and prolactin p < 0.01. On average, patients who have elevated PTH levels have lower values of FSH and LH, but higher prolactin values. Parathormone also shows the effect on beta estradiol at level p < 0.01, patients with higher PTH values have lower levels of beta estradiol.
The increase in the number of younger people with terminal renal insufficiency treated by repeated hemodialysis, often have endocrine disorders and elevated PTH. Normalization of PTH levels affects the normalization of sexual hormone levels and improves quality of life of patients on hemodialysis.
Disturbances in mineral and bone metabolism are common in patients with chronic kidney disease (CKD). Patients with CKD almost always develop secondary hyperplasia of the parathyroid glands, ...resulting in elevated blood levels of parathyroid hormone (PTH). The processes causing disordered mineral metabolism and bone disease have their onset in the early stages of CKD, continue throughout the course of progressive loss of kidney function and may be influenced beneficially or adversely by various therapeutic approaches used. It is should be emphasized that the care of CKD patients with bone disease requires frequent assessment of the various parameters (levels of calcium, phosphorus, vitamin D, PTH) and frequent evaluation of the therapies.
Pacijenti s terminalnim stadijem kroničnog zatajenja bubrega imaju smanjen odgovor na vakcinaciju protiv hepatitisa B. Cilj studije bio je utvrditi adekvatnost imunološkog odgovora prema novom ...protokolu protiv infekcije hepatitisom B. Studija je obuhvatila pacijente na kroničnom programu hemodijalize u razdoblju od 2008. do 2011. godine, na Klinici za hemodijalizu Kliničkog centra Univerziteta u Sarajevu. Novi protokol vakcinacije započeo je u rujnu 2009. godine. Novi protokol podrazumijevao je započinjanje vakcinacijom 6 mjeseci prije početka hemodijaliznog tretmana i nastavljanje tijekom 12 mjeseci, uz intrakutano umjesto supkutanog apliciranja prema praksi starog protokola vakciniranja u razdoblju od 2008. do 2011. godine. U studiju su bila uključena 64 pacijenta, 37 (57,81%) muškaraca i 27 (42,19%) žena. Pacijenti su bili podijeljeni u dvije skupine prema protokolu provedene vakcinacije protiv hepatitisa B. Niti jedan pacijent nije bio prethodno vakciniran, niti je u serumu imao pozitivna anti-HbS antitijela prije početka imunizacije protiv hepatitisa B. Prvu skupinu sačinjavali su pacijenti vakcinirani dozom supkutano prema protokolu koji je podrazumijevao vakcinaciju od 0, 3,6 i 12 mjeseci (M) u razdoblju praćenja od 2008. do 2009. godine. U prvoj je skupini bilo ukupno 28 pacijenata, prosječne dobi 55,17±11,84 godine uz prosječnu dužinu trajanja hemodijalize 24,65±5,32 mjeseci. Od ukupno 28 pacijenata u prvoj skupini ih 15 nije razvilo anti-HbS antitijela. Drugu skupinu sačinjavalo je 36 pacijenata, 21 (58,33%) muškarac i 15 (41,67%) žena, prosječne dobi 62,79±15,88 godina i srednje dužine trajanja liječenja hemodijaliznim tretmanom 22,16±24,53 mjeseci. U drugoj skupini je 5 bolesnika bilo potrebno aplicirati buster dozu vakcine nakon koje su 4 pacijenta pokazala adekvatan titar antiHbs. U drugoj skupini od 36 pacijenata vakciniranih prema novom protokolu, 31 je razvio antitijela anti Hbs, uz statistički značajnu razliku (p<0,005). Ukupan postotak pacijenata s pozitivnim anti Hbs antitijelima u drugoj skupini iznosio je 97,43%, a postotak onih koji su zahtijevali primjenu buster doze 12,82%. Autori zaključuju da su se vakciniranje pacijenata u krajnjem stadiju kroničnog bubrežnog zatajenja 6 mjeseci prije započinjanja hemodijaliznog tretmana, kao i intrakutana umjesto supkutane aplikacije vakcine, pokazale daleko učinkovijima u postizanju odgovarajućeg titra anti-HbS.
Central venous catheters (CVC) have become and indispensable form of haemodialysis access and represent, in our centre, about 8,58 % of the permanent vascular access with a total number of more than ...957 venous catheters in the past 8 years. We used double-lumen catheters.
The aim of this study was to identify the factors of the catheter dysfunction. We studied prospectively 23 chronic haemodialysed patients with CVC, 14 men and 9 women 63 +/- 14 (51-83), treated with haemodialysis for 3.7 +/- 4 (1-9) years. Catheters were inserted by percutaneous Seldinger techniques in right internal jugular vein. We studied the localization of the catheter tip: superior vena cava, right atrium, the blood pressure before and after haemodialysis, the interdialytic weight gain, and number of symptomatic episodes during 13 last dialysis (one month). The patients were divided into two groups: group I with usual adequate catheter function (n=17) and group II with frequent dysfunction (n=6).
In group I the catheters tip was in the right atrium, and in group II in the vena cava superior. Blood pressure was not different between the two groups. We found no correlation between central venous pressure, blood pressure, interdialytic weight gain and symptomatic hypotension, but there was a higher frequency of hypotension in the hypovolemic patients.
Optimal hemodynamic conditions will be provided by a catheters tip in the rights atrium and a central venous pressure over 5 mmHg, which can be provided with vascular filling or dry body weight.
The patients with the chronical programm for haemodialisys have the higher risk from getting ill virus hepatitis C in the realtion to the rest population.
Was the evaluation of the prevalence and ...incidence of hepatitis C at the Center for Haemodialisys CCU Sarajevo and the effect of the prevalentive measures on the incidence of the serum conversion of hepatitis C, in the period from 2002 till 2004 year.
By the examening is comprehended 155 patients aged 54,58 +/- 14,797 years, with the aproximative length of the haemodialisys 58,9 +/- 53,9 months. Patients at the chronic programm of the bicarbonite haemodialisys taree times per week, and antibodies on the hepatitis C were determined III generation. Also was determined PCR.
During the periiod of examination the dialized population was increased also 2002 year the prevalence of hepatitis C was 23,87% (37/155), in 2003 year 29,29% (46/157) and 2004 year the pregalence amounted 26,28% (46/175). Incidence of hepatitis C was significantly decreased in the course of the period of followup and in 2002 year was 16,21%, in 2003 year 13,04%, that in 2004 year would amount 4,34%, that is only in two patients occurred the serum conversion on hepatitis C.
By applying of the corresponding protocoles and their strict realization (desinfection of the hands, wearing of gloves, apparatus desinfection) and separation of the dialyzed monitors for anti HCV positive and anti HCV negative patients dicreased significantly the hepatitis C incidence in our dialyzed population. The strict application of the preventive measures can completely prevent the speading occurrence of hepatitis C on haemodialisys.
