COVID-19 infection in patients on long-term home parenteral nutrition for chronic intestinal failure.

BACKGROUND AND AIMS: To investigate the incidence and the severity of COVID-19 infection in patients enrolled in the database for home parenteral nutrition (HPN) for chronic intestinal failure (CIF) of the European Society for Clinical Nutrition and Metabolism (ESPEN). METHODS: Period of observation: March 1st, 2020 March 1st, 2021. INCLUSION CRITERIA: patients included in the database since 2015 and still receiving HPN on March 1st, 2020 as well as new patients included in the database during the period of observation. Data related to the previous 12 months and recorded on March 1st 2021: 1) occurrence of COVID-19 infection since the beginning of the pandemic (yes, no, unknown); 2) infection severity (asymptomatic; mild, no-hospitalization; moderate, hospitalization no-ICU; severe, hospitalization in ICU); 3) vaccinated against COVID-19 (yes, no, unknown); 4) patient outcome on March 1st 2021: still on HPN, weaned off HPN, deceased, lost to follow up. RESULTS: Sixty-eight centres from 23 countries included 4680 patients. Data on COVID-19 were available for 55.1% of patients. The cumulative incidence of infection was 9.6% in the total group and ranged from 0% to 21.9% in the cohorts of individual countries. Infection severity was reported as: asymptomatic 26.7%, mild 32.0%, moderate 36.0%, severe 5.3%. Vaccination status was unknown in 62.0% of patients, non-vaccinated 25.2%, vaccinated 12.8%. Patient outcome was reported as: still on HPN 78.6%, weaned off HPN 10.6%, deceased 9.7%, lost to follow up 1.1%. A higher incidence of infection (p = 0.04), greater severity of infection (p < 0.001) and a lower vaccination percentage (p = 0.01) were observed in deceased patients. In COVID-19 infected patients, deaths due to infection accounted for 42.8% of total deaths. CONCLUSIONS: In patients on HPN for CIF, the incidence of COVID-19 infection differed greatly among countries. Although the majority of cases were reported to be asymptomatic or have mild symptoms only, COVID-19 was reported to be fatal in a significant proportion of infected patients. Lack of vaccination was associated with a higher risk of death.

Recommendations for modern perioperative care for elective surgery: consensus of panel of exerts.

INTRODUCTION: Correct surgical technique and perioperative care are two factors that can reduce the number of complications, improve treatment outcomes and shorten the length of hospital stay. The introduction of enhanced recovery protocols has changed the approach to patient care in some centers. However, there are significant differences among centers, and in some the standard of care has remained unchanged. AIM: the goal of the panel was to develop recommendations for modern perioperative care in accordance with current medical knowledge in order to reduce the number of complications associated with surgical treatment. An additional goal was to optimize and standardize perioperative care among Polish centers. MATERIALS AND METHODS: the development of these recommendations was based on a review of the available literature from the PubMed, Medline and Cochrane Library databases from January 1, 1985 to March 31, 2022, with particular emphasis on systematic reviews and clinical recommendations of recognized scientific societies. Recommendations were formulated in a directive form and were assessed using the Delphi method. RESULTS AND CONCLUSIONS: 34 recommendations for perioperative care were presented. They cover aspects of pre-, intra- and post-operative care. Implementation of the presented rules allows to improve the results of surgical treatment.

Foods for Special Medical Purposes in Home Enteral Nutrition-Clinical Practice Experience. Multicenter Study.

Background: Enteral nutrition (EN) with foods for special medical purposes (FSMP) is recommended for most patients on home enteral nutrition (HEN). Although there are disease-specific guidelines for energy, protein, and micronutrient provision, only a few studies are showing real-life experience in the long-term use of FSMP. Methods: In a multicenter study, the influence of the FSMP composition and administration technique (bolus vs. continuous) on protein and energy provision in HEN was analyzed. Provision of vitamins and minerals was compared to recommended daily allowance (RDA) and upper tolerable limit (UL). Results: Approximately, 772 patients on HEN, mostly (88.6%) with oncological and neurological diseases, were enrolled. The patients on standard FSMP received less protein and energy than those on hypercaloric and protein enriched despite receiving higher volumes of EN (p < 0.05). No differences were observed in jejunal feeding with oligomeric vs. polymeric FSMP in terms of energy, protein, and volume. Continuous gastric feeding provided more protein, energy, and volume vs. bolus feeding (p < 0.05). Significant number of patients received less than 100% RDA of vitamin D (50.5%), vitamin B3 (49%), vitamin K (21.8%), vitamin B5 (64.3%), vitamin B9 (60%). Majority of the patients received less than 100% RDA of sodium (80.2%), potassium (99%), chloride (98%), calcium (67%), magnesium (87%), fluoride (99%), and iodine (43%). Approximately, 43.63% of cancer and 49.9% of neurological patients received less than 1 g/kg/day of protein and 51.7% of cancer and 55.5% of neurological patients received less than 25 kcal/kg/day. Conclusion: Awareness of the available compositions of FSMP and advantageous profiles of specific diets may lead to the implementation of recommendations for EN. HEN professionals need to analyze all the patient's needs and requirements to provide more tailored matching of nutritional support.

Characteristics of adult patients with chronic intestinal failure due to short bowel syndrome: An international multicenter survey.

BACKGROUND AND AIMS: The case-mix of patients with intestinal failure due to short bowel syndrome (SBS-IF) can differ among centres and may also be affected by the timeframe of data collection. Therefore, the ESPEN international multicenter cross-sectional survey was analyzed to compare the characteristics of SBS-IF cohorts collected within the same timeframe in different countries. METHODS: The study included 1880 adult SBS-IF patients collected in 2015 by 65 centres from 22 countries. The demographic, nutritional, SBS type (end jejunostomy, SBS-J; jejuno-colic anastomosis, SBS-JC; jejunoileal anastomosis with an intact colon and ileocecal valve, SBS-JIC), underlying disease and intravenous supplementation (IVS) characteristics were analyzed. IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorized as <1, 1-2, 2-3 and >3 L/day. RESULTS: In the entire group: 60.7% were females and SBS-J comprised 60% of cases, while mesenteric ischaemia (MI) and Crohn' disease (CD) were the main underlying diseases. IVS dependency was longer than 3 years in around 50% of cases; IVS was infused ≥5 days/week in 75% and FE in 10% of cases. Within the SBS-IF cohort: CD was twice and thrice more frequent in SBS-J than SBS-JC and SBS-JIC, respectively, while MI was more frequent in SBS-JC and SBS-JIC. Within countries: SBS-J represented 75% or more of patients in UK and Denmark and 50-60% in the other countries, except Poland where SBS-JC prevailed. CD was the main underlying disease in UK, USA, Denmark and The Netherlands, while MI prevailed in France, Italy and Poland. CONCLUSIONS: SBS-IF type is primarily determined by the underlying disease, with significant variation between countries. These novel data will be useful for planning and managing both clinical activity and research studies on SBS.

Organizational issues of home parenteral nutrition during COVID-19 pandemic: Results from multicenter, nationwide study.

OBJECTIVES: Patients on home parenteral nutrition (HPN) are prone to severe complications of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The pandemic requires adaptation of the health care standards, including epidemiologic surveillance, logistics of home supply, and monitoring. Potential lack of medical professionals may worsen the standard of care. The aim of this study was to evaluate the medical staff resources in HPN units. RESULTS: The study was conducted by major Polish scientific societies in clinical nutrition. A questionnaire was distributed among all Polish adult HPN centers concerning statistics from the first 3 mo of the pandemic (March through May 2020). Data on medical staff resources and organizational issues of the units were collected. Modifications of the home procedures, SARS-CoV-2 infection rates of HPN patients and health care workers (HCW) were analyzed. Influence of the pandemic on the rates of new qualifications for home artificial nutrition (HAN) was estimated. Fourteen of 17 adult Polish HPN units took part in the study. The point prevalence of HPN in Poland was 30.75/1 million citizens. Of HCWs, 344 were involved in patient care in Polish HPN units; 18.9% were physicians (49% surgeons, 18.46% internal medicine specialists, 15.38% anesthesiologists, 7.69% pediatricians, 1.54% palliative care specialists), 32.27% nurses, 5.23% dietitians, 9.01% pharmacists, 4.94% pharmacy technicians, 3.2% pharmacy assistants, 5.81% administrative workers, 3.49% physiotherapists. HAN patient-to-HCW ratios for physicians, nurses, pharmacists, dietitians were 49.5, 29.15, 111.6, and 181.6, respectively. Medium ages of physicians and nurses were 45.6 and 44.15 y, respectively. Slightly less than half (53.8%) of physicians and 31.53% of nurses worked parallelly in hospital wards. Thirty-one pharmacists overall were working in all HPN units (2.21 per unit) as were 18 dietitians (1.3 per unit). Nine patients had a confirmed COVID-19 infection (four HPN, five home enteral nutrition). All the units introduced telemedicine solutions in the first months of the pandemic. The number of new qualifications for HPN and home enteral nutrition in the units did not significantly decline from March through May in comparison with a similar period in 2019. CONCLUSIONS: A shortage of HPN medical professionals requires attention when planning health care organization, especially during a pandemic. Severe restrictions in public health systems may not reduce the number of new qualifications for the HPN procedure. There is a need for the continuation of data collection during the evolution of the pandemic as it may have a detrimental effect on HPN including serious issues with access to professional HCWs.

Home medical nutrition during SARS-CoV-2 pandemic - A position paper.

BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a worldwide rapidly spreading illness, Coronavirus Disease 2019 (COVID-19). Patients fed enterally and parenterally at home are exposed to the same risk of infection as the general population, but more prone to complications than others. Therefore the guidance for care-givers and care-takers of these patients is needed. METHODS: The literature search identified no relevant systematic reviews or studies on the subject. Therefore a panel of 21 experts from 13 home medical nutrition (HMN) centres in Poland was formed. Twenty-three key issues relevant to the management of SARS-CoV-2 infection or COVID-19 in the HMN settings were identified and discussed. Some statements diverge from the available nutrition, surgical or ICU guidelines, some are based on the best available experience. Each topic was discussed and assessed during two Delphi rounds subsequently. Statements were graded strong or weak based on the balance between benefit and harm, resource and cost implications, equity, and feasibility. RESULTS: the panel issued 23 statements, all of them were graded strong. Two scored 85.71% agreement, eleven 95.23%, and ten 100%. The topics were: infection control, enrolment to HMN, logistics and patient information. CONCLUSIONS: the position paper present pragmatic statements for HMN to be implemented in places without existing protocols for SARS-CoV-2 pandemic. They represent the state of knowledge available at the moment and may change should new evidence occurs.

Home Enteral Nutrition in Adults-Nationwide Multicenter Survey.

Home enteral nutrition (HEN) is an important part of the health care system, with a growing population of patients around the world. The aim of our study was to analyze one of the largest cohorts of HEN patients to provide the most recent data available in European literature. A multicenter, nation-wide survey in the period of 1 January 2018-1 January 2019 was performed in Poland. Data concerning adult patients on HEN in 2018 during 1 year of observation time were analyzed: demographic characteristics, primary disease, technique of enteral feeding, diet formulation and amount of energy provided. A total of 4586 HEN patients (F: 46.7%, M: 53.3%) were included in the study. The primary diseases were: 54.5% neurological (17.4%-neurovascular, 13.7%-neurodegenerative), 33.9% cancer (20.2%-head and neck, 11.7%-gastrointestinal cancer), 2.5%-gastroenterology, 1.5%-inherited diseases. Of new registrations in 2018-cancer patients 46.3%, neurological patients 45.1%. The median age overall was: 64 yr., BMI-20.2 kg/m2, NRS 2002 score-4.28. A total of 65% of patients were treated with PEG, 11.6% with surgical gastrostomy, 14.3% with naso-gastric tube and 7% with jejunostomy. Boluses were the most common method of feeding (74.4%). Gravity flow was used in 17.6% and peristaltic pump was used in 8% patients. The median energy provision was 1278 kcal/day and 24 kcal/kg/day. The most commonly used diets were: isocaloric (28.1%), protein-enriched isocaloric (20%) and protein-enriched hypercaloric (12%). The median overall duration of HEN was 354 days, 615 days for neurological and 209 days for cancer patients. A number of new registrations of cancer patients was significant and long duration of HEN in this group is encouraging. A developing spectrum of enteral formulas available enables more specified nutritional interventions.

Intravenous supplementation type and volume are associated with 1-year outcome and major complications in patients with chronic intestinal failure.

BACKGROUND AND AIM: No marker to categorise the severity of chronic intestinal failure (CIF) has been developed. A 1-year international survey was carried out to investigate whether the European Society for Clinical Nutrition and Metabolism clinical classification of CIF, based on the type and volume of the intravenous supplementation (IVS), could be an indicator of CIF severity. METHODS: At baseline, participating home parenteral nutrition (HPN) centres enrolled all adults with ongoing CIF due to non-malignant disease; demographic data, body mass index, CIF mechanism, underlying disease, HPN duration and IVS category were recorded for each patient. The type of IVS was classified as fluid and electrolyte alone (FE) or parenteral nutrition admixture (PN). The mean daily IVS volume, calculated on a weekly basis, was categorised as <1, 1-2, 2-3 and >3 L/day. The severity of CIF was determined by patient outcome (still on HPN, weaned from HPN, deceased) and the occurrence of major HPN/CIF-related complications: intestinal failure-associated liver disease (IFALD), catheter-related venous thrombosis and catheter-related bloodstream infection (CRBSI). RESULTS: Fifty-one HPN centres included 2194 patients. The analysis showed that both IVS type and volume were independently associated with the odds of weaning from HPN (significantly higher for PN <1 L/day than for FE and all PN >1 L/day), patients' death (lower for FE, p=0.079), presence of IFALD cholestasis/liver failure and occurrence of CRBSI (significantly higher for PN 2-3 and PN >3 L/day). CONCLUSIONS: The type and volume of IVS required by patients with CIF could be indicators to categorise the severity of CIF in both clinical practice and research protocols.

Home parenteral nutrition provision modalities for chronic intestinal failure in adult patients: An international survey.

BACKGROUND & AIMS: The safety and effectiveness of a home parenteral nutrition (HPN) program depends both on the expertise and the management approach of the HPN center. We aimed to evaluate both the approaches of different international HPN-centers in their provision of HPN and the types of intravenous supplementation (IVS)-admixtures prescribed to patients with chronic intestinal failure (CIF). METHODS: In March 2015, 65 centers from 22 countries enrolled 3239 patients (benign disease 90.1%, malignant disease 9.9%), recording the patient, CIF and HPN characteristics in a structured database. The HPN-provider was categorized as health care system local pharmacy (LP) or independent home care company (HCC). The IVS-admixture was categorized as fluids and electrolytes alone (FE) or parenteral nutrition, either commercially premixed (PA) or customized to the individual patient (CA), alone or plus extra FE (PAFE or CAFE). Doctors of HPN centers were responsible for the IVS prescriptions. RESULTS: HCC (66%) was the most common HPN provider, with no difference noted between benign-CIF and malignant-CIF. LP was the main modality in 11 countries; HCC prevailed in 4 European countries: Israel, USA, South America and Oceania (p < 0.001). IVS-admixture comprised: FE 10%, PA 17%, PAFE 17%, CA 38%, CAFE 18%. PA and PAFE prevailed in malignant-CIF while CA and CAFE use was greater in benign-CIF (p < 0.001). PA + PAFE prevailed in those countries where LP was the main HPN-provider and CA + CAFE prevailed where the main HPN-provider was HCC (p < 0.001). CONCLUSIONS: This is the first study to demonstrate that HPN provision and the IVS-admixture differ greatly among countries, among HPN centers and between benign-CIF and cancer-CIF. As both HPN provider and IVS-admixture types may play a role in the safety and effectiveness of HPN therapy, criteria to homogenize HPN programs are needed so that patients can have equal access to optimal CIF care.

Antibiotic Resistance and Genotypes of Helicobacter pylori Strains in Patients with Gastroduodenal Disease in Southeast Poland.

The aim of this study was to investigate genetic diversity of Helicobacter pylori virulence markers to predict clinical outcome as well as to determine an antibiotic susceptibility of H. pylori strains in Poland. Gastric biopsies from 132 patients with gastrointestinal disorders were tested for presence of H. pylori with the use of rapid urease test, microbial culture, and polymerase chain reaction (PCR) detection. The genetic diversity of 62 H. pylori positive samples was evaluated by detection of cagA and PCR-typing of vacA and iceA virulence-associated genes. Most common H. pylori genotypes were cagA(+)vacAs1m2 (27.4%) and cagA(-)vacAs2m2 (24.2%). In logistic regression analysis, we recognized the subsequent significant associations: gastritis with ureC, i.e., H. pylori infection (p = 0.006), BMI index (p = 0.032); and negatively with iceA1 (p = 0.049) and peptic ulcer with cagA (p = 0.018). Thirty-five H. pylori strains were cultured and tested by E-test method showing that 49% of strains were resistant to at least one of the tested antibiotics. This is the first study that reports the high incidence and diversity of allelic combination of virulence genes in gastroduodenitis patients in Poland. Genotyping of H. pylori strains confirmed the involvement of cagA gene and vacAs1m1 genotype in development and severity of gastric disorder.

Clinical classification of adult patients with chronic intestinal failure due to benign disease: An international multicenter cross-sectional survey.

BACKGROUND & AIMS: The aim of the study was to evaluate the applicability of the ESPEN 16-category clinical classification of chronic intestinal failure, based on patients' intravenous supplementation (IVS) requirements for energy and fluids, and to evaluate factors associated with those requirements. METHODS: ESPEN members were invited to participate through ESPEN Council representatives. Participating centers enrolled adult patients requiring home parenteral nutrition for chronic intestinal failure on March 1st 2015. The following patient data were recorded though a structured database: sex, age, body weight and height, intestinal failure mechanism, underlying disease, IVS volume and energy need. RESULTS: Sixty-five centers from 22 countries enrolled 2919 patients with benign disease. One half of the patients were distributed in 3 categories of the ESPEN clinical classification. 9% of patients required only fluid and electrolyte supplementation. IVS requirement varied considerably according to the pathophysiological mechanism of intestinal failure. Notably, IVS volume requirement represented loss of intestinal function better than IVS energy requirement. A simplified 8 category classification of chronic intestinal failure was devised, based on two types of IVS (either fluid and electrolyte alone or parenteral nutrition admixture containing energy) and four categories of volume. CONCLUSIONS: Patients' IVS requirements varied widely, supporting the need for a tool to homogenize patient categorization. This study has devised a novel, simplified eight category IVS classification for chronic intestinal failure that will prove useful in both the clinical and research setting when applied together with the underlying pathophysiological mechanism of the patient's intestinal failure.

Is additional enrichment of diet in branched-chain amino acids or glutamine beneficial for patients receiving total parenteral nutrition after gastrointestinal cancer surgery?

OBJECTIVES: Total Parenteral Nutrition (TPN) is necessary in patients unable to receive oral or enteral feeding for a period of at least 7 days. Branched-chain amino acids (BCAA): valine (Val), leucine (Leu), and isoleucine (Ile) are essential amino acids, which are important regulators in protein metabolism. They are also the main nitrogen source for glutamine synthesis in muscles. In this process they undergo irreversible degradation and cannot be reutilised for protein synthesis. In catabolic states, like cancers, glutamine demand increases and therefore also its utilisation, which can decrease the level of BCAA required for Gln synthesis. The purpose of this study was to evaluate the necessity of BCAA or glutamine-enriched TPN in patients after gastrointestinal cancers surgery. MATERIAL AND METHODS: Our aim was to investigate changes of plasma BCAA and glutamine concentrations in patients operated for colorectal, small intestine or pancreatic cancer and who are either receiving TPN or not in the postoperative period. Free amino acids plasma concentrations were determined by the ion-exchange chromatography. RESULTS: Surgery in the control group caused a decrease in Val, Ile and Leu concentrations in the postoperative period. In TPN patients this depression was inhibited beginning from the third day after surgery, except for Val and Leu in colorectal cancer group. In control and TPN patient groups, Gln concentration decreased after the surgery and subsequently increased beginning from the third day after the operation. CONCLUSIONS: Gastrointestinal cancer patients' surgery results in decrease in BCAA concentrations. Standard TPN exerts a beneficial effect on the BCAA level in patients with pancreatic and small intestine cancer. In colorectal cancer such TPN should be enriched with Leu and Val.

Evaluation of factors associated with the nutritional mixture leading to liver complications in patients treated by means of parenteral nutrition at home.

UNLABELLED: The major problem of total parenteral treatment consists in the balancing of the source and dose of the nutritional mixture, so as to not deepen malnutrition with a positive impact on the patients' organism. The aim of the study was to evaluate selected factors that induce hepato-biliary complications in patients treated by means of parenteral nutrition at home. MATERIAL AND METHODS: The retrospective study comprised 70 patients with biochemistry performed every three months. Considering statistical analysis patients were allocated to four groups, depending on the period of treatment. Group A analysis results were based on the activity of aminotransferases, group B on the activity of bilirubin. Both groups A and B were additionally divided into group I where we assigned normal values of control lab results, and group II with improper results after treatment. RESULTS: Differences between groups Ia vs IIa were presented on the basis of the daily supply of glucose: mean- 2.52 vs 3.49 g/kg (p=0.000003), glucose/lipids ratio: mean- 3.76 vs 4.90 g/kg (p=0.0001), daily non-protein energy: mean- 16.73 vs 21.06 kcal/kg (p=0.0001). Differences between groups Ib vs IIb were presented on the basis of the daily supply of glucose: mean- 2.76 vs 3.46 g/kg (p=0.0007), glucose/lipids ratio: mean- 3.98 vs 5.13 g/kg (p=0.01), daily non-protein energy: mean-17.96 vs 20.36 kcal/kg (p=0.04). Based on the above-mentioned analysis the main goal in the prevention of hepatic complications should lead to the reduction of the dose of glucose. Increased glucose supply leads to increased number of hepato-biliary complications. CONCLUSIONS: Based on obtained results we were able to conclude that in case of liver complications associated with parenteral nutrition, proper management consists in the modification of nutritional mixtures (reduction in the daily glucose supply and change in the proportions of extra-protein energy). Such management has the greatest clinical effect. When determining the composition of the nutritional mixture one should adjust the glucose supply, so as to offset both sources of extra-protein energy.

Home enteral nutrition in children--2010 nationwide survey of the Polish Society for Clinical Nutrition of Children.

Published epidemiologic data on the administration rates of enteral/parenteral home nutrition is very limited. The aim of this first nationwide study was to assess the availability of pediatric home enteral nutrition (HEN) services in Poland. The questionnaire was sent to all regional centers providing pediatric HEN services in Poland (n = 14). The analysis included the number of pediatric patients who received HEN in 2010, their demographic characteristics and geographical distribution. Furthermore, the distributions of indications and methods of enteral nutrition administration were analyzed, along with the reasons of withdrawal from the HEN program. The number and fraction of children receiving HEN increased in 2010, from 433 (11.34 per 1 million inhabitants) on January 1st to 525 (13.75) on December 31st. Marked differences were observed in geographical distribution of this parameter, from zero to up to 30 pediatric patients per 1 million inhabitants. Median age of patients was 6 years (range: 9 months-18 years). In most cases, HEN was prescribed due to neurological disorders (n = 337, 64.2%), and administered by means of gastrostomy (n = 450, 85.71%). This study revealed the dynamic development of pediatric HEN services in Poland but also documented their potential regional shortages.

Antioxidants in patients receiving total parenteral nutrition after gastrointestinal cancer surgery.

Total parenteral nutrition (TPN) is essential for patients with postoperative impairing gastrointestinal function who are unable to receive and absorb oral/enteral feeding for at least 7 days. Oxidative stress plays a major role in the ethiopathogenesis of cancers. In this study, total antioxidant status (TAS), glutathione peroxidase (GPx), superoxide dismutase, malondialdehyde and ascorbic acid were studied in patients operated because of small intestine, colorectal or pancreatic cancer and subsequently receiving TPN in comparison with patients receiving standard nutrition after the operation. TAS level and GPx activity were decreased in patients with small intestine cancer but did not differ in patients with colorectal and pancreatic cancer before and after surgery. In all patient groups receiving TPN, superoxide dismutase activity after the surgery was kept at the same level as before. On the fifth day after the surgery, malondialdehyde concentration in each group was restored to the value observed before surgery. On the fifth day of TPN treatment, ascorbic acid concentration was increased in every group of patients. TPN applied during the postoperative period alleviates oxidative stress resulting from surgery. In the case of small intestine cancer, the addition of vitamins and antioxidants to the nutrition mixture seems to result in depletion of antioxidant enzymes' activities.

[Analysis of early surgical complications after strumectomy]. / Analiza przyczyn wczesnych powiklan po strumektomii.

UNLABELLED: The aim of the study was the analysis of early surgical complications after strumectomy. MATERIAL AND METHODS: The study involved 578 patients operated on in I Clinic of General Surgery and Transplant at the Medical Academy in Lublin in the years 1999-2002. The largest group of the operated patients was the one with a non-toxic (neutral) goitre (60.1%). Most of the patients in this group had multinodular neutral goitre. The amount of the surgically treated patients because of the hyperactive goitre prevailed in this group. RESULTS: Early postoperative complications were observe d in 35 cases, which comprise 6.05% of the operated patients. On the basis of the obtained results, we stated that there are evident differences in the frequency of occurrence of early complications depending on the type of the goitre. We concluded that statistically they were more frequent in patients operated on because of Graves-Basedov disease as well as in patients with Hashimoto goitre (chi2 test p < 0.001). The amount of the strumectomy operations conducted annually by a surgeon did not have direct influence on the occurrence of the early complications. CONCLUSIONS: Early postoperative complications after strumectomy are more frequent in patients operated on because of diseases of autoimmunological basis. Operations of the thyroid gland and trainings in the surgery of the thyroid gland should take place in centers where large amount of such operations are conducted.

Estimation of CA 125 concentration in patients with congestive heart failure.

Tumour marker CA 125 is used in the monitoring results of treatment woman with ovarian cancer. Its diagnostic effectiveness in selected groups of patients is defined by sensitivity estimated at approximately 75% and specifity at 95%. In practice diagnostic specificity of CA 125 concentration is lower as it is limited by the increase of concentration different tumour diseases (bladder cancer) and non-tumour diseases (pericardial inflammation). The aim of the paper was to estimate CA 125 concentration in patients with congestive heart failure as well as to define the range of changes taking place according to the advancement of the disease. The research included 39 patients: 20 women and 19 men aged 45-75 with diagnosed congestive heart failure graded II-IV in the NYHA classification. It has been found that CA 125 concentration in blood serum of the patiens with congestive heart failure was on average approximately 35.4 +/- 24.8 U/ml and was included in the range from 5.6 to 874 U/ml (limit value 21 U/ml). The concentration increase above the limit value was observed in 34% of patients. Significant statistic differences in CA 125 concentration rates were dependent on the disease advancement. The highest concentration rates were observed in patients classified in group IV NYHA. The results that have been obtained allow us to draw a conclusion that right interpretation of CA 125 concentration in clinical practice (screening examinations, establishment of the level of advancement, prognostication as well as monitoring the ovarian cancer treatment) brings the necessity of taking into consideration the degree of congestive heart failure.
