Factors associated with infection amongst paediatric patients with systemic lupus erythematosus treated in the intensive care unit.

OBJECTIVE: To identify determinants and outcomes associated with infection in paediatric systemic lupus erythematosus (SLE) patients at admission and during hospitalization in intensive care units (ICUs). PATIENTS AND METHODS: A retrospective cohort study of paediatric SLE patients admitted to two ICUs was conducted. Frequency and risk factors of infection as well as mortality were studied. RESULTS: Seventy-three infection episodes amongst 55 patients were analysed. The median age was 14.4 years (IQR 12.5-16). The median SLEDAI was 16 (IQR 12-20). Twenty-nine episodes were documented at admission; the CRP was higher in these patients (6.58 versus 1.04 mg/dl, p<0.001) than in non-infected patients, even after multivariate adjustment (OR 8.6, 95% CI = 2.1-34.8, p = 0.003). Twenty-five (34.7%) episodes occurred during hospitalization. Lupus activity (OR 1.14, 95% CI = 1.01-1.27, p = 0.029), cyclophosphamide (OR 17.9, 95% CI = 2-156, p = 0.009) and mechanical ventilation (OR 16, 95% CI = 2.1-122, p = 0.008) were associated with infection. Ten episodes (14%) led to death. Admission to the ICU due to infection was strongly associated with mortality (90% versus 31.8%, OR 19.4, 95% CI = 2.3-163, p = 0.006). CONCLUSION: In paediatric lupus patients admitted to the ICU, elevated CRP should alert clinicians to possible infection. During hospitalization, SLE activity and cyclophosphamide were associated with infection. Infection at admission to the ICU was strongly associated with mortality.

Diabetes, undernutrition, migration and indigenous communities: tuberculosis in Chiapas, Mexico.

We investigated the distribution of comorbidities among adult tuberculosis (TB) patients in Chiapas, the poorest Mexican state, with a high presence of indigenous population, and a corridor for migrants from Latin America. Secondary analysis on 5508 new adult TB patients diagnosed between 2010 and 2014 revealed that the most prevalent comorbidities were diabetes mellitus (DM; 19.1%) and undernutrition (14.4%). The prevalence of DM in these TB patients was significantly higher among middle aged (41-64 years) compared with older adults (⩾65 years) (38.6% vs. 23.2%; P < 0.0001). The prevalence of undernutrition was lower among those with DM, and higher in communities with high indigenous presence. Immigrants only comprised 2% of all TB cases, but were more likely to have unfavourable TB treatment outcomes (treatment failure, death and default) when compared with those born in Chiapas (29.5% vs. 11.1%; P < 0.05). Unfavourable TB outcomes were also more prevalent among the TB patients with undernutrition, HIV or older age, but not DM (P < 0.05). Our study in Chiapas illustrates the challenges of other regions worldwide where social (e.g. indigenous origin, poverty, migration) and host factors (DM, undernutrition, HIV, older age) are associated with TB. Further understanding of these critical factors will guide local policy makers and health providers to improve TB management.

Chemical constituents and their antibacterial activity from the tropical endophytic fungus Diaporthe sp. F2934.

AIMS: To isolate, characterize and determine the antibacterial activities of compounds produced by the endophytic fungus Diaporthe sp. F2934, cultivated on malt extract agar. METHODS AND RESULTS: The fungus was cultivated aseptically in Petri dishes containing malt extract agar at 25°C for 15 days. Crude extract was obtained from mycelium using ethyl acetate and sonication, and was fractioned using classic chromatography and HPLC. The structures of phomosines and chromanones were established by NMR experiments including HMQC, HMBC and COSY. Their molecular formulas were determined by ESI-TOFMS. We obtained six compounds: (1) 4H-1-benzopyra-4-one-2,3-dihydro-5-hydroxy-2,8-dimetyl, (2) 4H-1-benzopyran-4-one-2,3-dihydro-5-hydroxy-8-(hydroxylmethyl)-2-methyl, (3) 4H-1-benzopyra-4-one-2,3-dihydro-5-methoxyl-2,8-dimetyl, (4) phomosine A, (5) phomosine D and (6) phomosine C. Isolated compounds 1, 2 and 5 were inactive against 15 micro-organisms, but phomosines A and C were active against diverse Gram-negative and Gram-positive bacteria. CONCLUSIONS: A group of new chromanones and known phomosines have been isolated from the genus Diaporthe (Diaporthe sp. F2934). The results obtained confirm the wide chemical diversity produced by endophytic fungi, specifically the genus Diaporthe. In addition, phomosines A and C may be considered as antimicrobial agents that can be used to guide the development of new antibiotics. SIGNIFICANCE AND IMPACT OF THE STUDY: Our phylogenetic analysis places Diaporthe sp. F2934 as sister to the Diaporthe cynaroidis clade. Three chromanones were isolated and identified, for the first time, using crude extract obtained from Diaporthe F2934. From this extract phomosines A, C and D were also purified. Regarding Staphylococcus aureus, the inhibition zone diameter (IZD) for phomosine A was 20% higher than the standard drug, vancomycin. When cultivated as described here, Diaporthe sp. F2934 produced new and antimicrobial compounds.

Next-generation sequencing detects repetitive elements expansion in giant genomes of annual killifish genus Austrolebias (Cyprinodontiformes, Rivulidae).

Among Neotropical fish fauna, the South American killifish genus Austrolebias (Cyprinodontiformes: Rivulidae) constitutes an excellent model to study the genomic evolutionary processes underlying speciation events. Recently, unusually large genome size has been described in 16 species of this genus, with an average DNA content of about 5.95 ± 0.45 pg per diploid cell (mean C-value of about 2.98 pg). In the present paper we explore the possible origin of this unparallel genomic increase by means of comparative analysis of the repetitive components using NGS (454-Roche) technology in the lowest and highest Rivulidae genomes. Here, we provide the first annotated Rivulidae-repeated sequences composition and their relative repetitive fraction in both genomes. Remarkably, the genomic proportion of the moderately repetitive DNA in Austrolebias charrua genome represents approximately twice (45%) of the repetitive components of the highly related rivulinae taxon Cynopoecilus melanotaenia (25%). Present work provides evidence about the impact of the repeat families that could be distinctly proliferated among sublineages within Rivulidae fish group, explaining the great genome size differences encompassing the differentiation and speciation events in this family.

Burst speciation processes and genomic expansion in the neotropical annual killifish genus Austrolebias (Cyprinodontiformes, Rivulidae).

The extent to which genome sizes and other nucleotypic factors influence the phyletic diversification of lineages has long been discussed but remains largely unresolved. In the present work, we present evidence that the genomes of at least 16 species of the neotropical rivulid killifish genus Austrolebias are unusually large, with an average DNA content of about 5.95 ± 0.45 picograms per diploid cell (mean C-value of about 2.98 pg). They are thus larger than the genomes of very nearly all other diploid, i.e. non-(paleo) polyploid species of actinopterygian fishes so far reported. Austrolebias species appear to be conventional diploids in all other respects and there is no reason to believe that they arise from polyploid ancestors. The genome sizes reported for other rivulid killifishes, including a putative sister group, are considerably smaller and fall within the range typical of most other cyprinodontoid species. Therefore, it appears that the ancestor(s) of contemporary Austrolebias have undergone one or more episodes of genome expansion encompassing sudden speciation process during the Pleistocene. In addition, these findings are consistent with the hypothesis of a positive correlation between species richness and genome size.

Cost-Analysis of Subcutaneous vs Intravenous Administration of Natalizumab Based on Patient Care Pathway in Multiple Sclerosis in Spain.

INTRODUCTION: A subcutaneous (SC) formulation of natalizumab has been recently authorised for multiple sclerosis patients. This study aimed to assess the implications of the new SC formulation, and to compare the annual treatment costs of SC versus intravenous (IV) natalizumab therapy from both the Spanish healthcare system (direct health cost) and the patient (indirect cost) perspectives. METHODS: A patient care pathway map and a cost-minimisation analysis were developed to estimate SC and IV natalizumab annual costs over a 2-year time horizon. Considering the patient care pathway and according to natalizumab experience (IV) or estimation (SC), a national expert panel involving neurologists, pharmacists, and nurses provided information/data regarding resource consumption for drug and patient preparation, administration, and documentation. One hour of observation was applied to the first six (SC) or 12 (IV) doses, and 5 min for successive doses. The Day hospital (infusion suite) facilities at a reference hospital were considered for IV administrations and the first six SC injections. For successive SC injections, either a reference hospital or regional hospital in a consulting room was considered. Productivity time associated with travel (56 min to reference hospital, 24 min to regional hospital) and waiting time pre- and post-treatment (SC 15 min, IV 25 min) were assessed for patients and caregivers (accompanying 20% of SC and 35% of IV administrations). National salaries for healthcare professionals were used for cost estimation (€, year 2021). RESULTS: At years 1 and 2, total time and cost savings (excluding drug acquisition cost) per patient, driven by saving on administration and patient and caregiver productivity for SC at a reference hospital versus IV at a reference hospital, were 116 h (a reduction of 54.6%) and €3682.82 (a reduction of 66.2%). In the case of natalizumab SC at a regional hospital, the total time and cost saving were 129 h (a reduction of 60.6%) and €3883.47 (a reduction of 69.8%). CONCLUSIONS: Besides the potential benefits of convenient administration and improving work-life balance, as suggested by the expert panel, natalizumab SC was associated with cost savings for the healthcare system by avoiding drug preparation, reducing administration time, and freeing up infusion suite capacity. Additional cost savings could be derived with regional hospital administration of natalizumab SC by reducing productivity loss.

Survey of patient perception of pre-analytical requirements for blood testing in the UK and RoI.

BACKGROUND: A patient survey developed by the Pre-Analytical Phase Special Interest Group of the Association for Clinical Biochemistry and Laboratory Medicine (ACB-PA-SIG) was conducted during November and December 2019. The survey aimed to determine the quality of information provided to patients in preparation for their blood test(s). In addition, the ACB-PA-SIG provide a number of recommendations, which, if adopted, may yield higher quality test results and improve patient management. METHODS: The survey was distributed at phlebotomy suites in two Hospitals: Ipswich Hospital (United Kingdom [UK]), and Cork University Hospital (Republic of Ireland [RoI]). RESULTS: Overall, 235 survey responses were received from the two sites. A total of 103 respondents received no information about preparing for their blood test and 92 had been told they did not need to fast. None of the patients surveyed had been instructed to fast for 12 h. Twenty-two patients had been told to avoid certain foods, drinks or medication, 14 were told to avoid strenuous activity and 41 respondents had been informed of the need to avoid alcohol/smoking prior to their blood test. Overall, only approximately 78 felt well informed about the blood taking process. CONCLUSIONS: Based on the results of this survey, the ACB-PA-SIG conclude that: (1) clinicians should provide clear written information to patients regarding pre-analytical requirements; and (2) effective communication between laboratories and General Practitioners is required to disseminate information. In this paper, the ACB-PA-SIG provide a list of pre-analytical recommendations to standardize and improve practice across the UK and RoI.

First evaluation of neustonic microplastics in the Macaronesian region, NE Atlantic.

Marine microplastic pollution is an issue of great concern nowadays since high concentrations have been detected in the ocean, mainly in the subtropical gyres that accumulate this type of debris. The long-term effects of this pollution on ecosystems and marine biota are still unknown. The aim of this study is to quantify and characterise microplastics and neustonic zooplankton in sub-surface waters of the Macaronesian region, an area that has been little studied to date. Our results show a great variability in the concentration of microplastics with values between 15,283 items/km2 in Los Gigantes (Tenerife, Canary Islands) and 1,007,872 items/km2 in Las Canteras (Gran Canaria, Canary Islands). The main types of debris found were plastic fragments and fibres. The abundances of neustonic zooplankton were also very variable between the different sampling areas, being the main components copepods and eggs. Regarding the microplastics-zooplankton ratio, values were obtained between 0.002 and 0.22. In Las Canteras, the highest accumulation zone, was found twice as much microplastics as zooplankton for the 1-5 mm fraction in dry weight. These values highlight the potential hazard of microplastics - and its associated chemical contaminants - for marine biota, especially for large filter feeders.

[Cardio-metabolic properties of manidipine: beyond lowering arterial pressure?]. / Propiedades cardiometabólicas del manidipino: ¿más allá de la reducción de la presión arterial?

From its introduction in the decade of the 70's the evolution of the calcium channel blockers has allowed to resolve the uncertainty initially generated by those first generation drugs. These, are characterized by a smaller oral availability, a fast vasodilator action and a short duration of action. Manidipine arises as a dihydropyridine calcium antagonist of third generation with real additional advantages regarding to previous generations. They show high lipophilia, a more prolonged action and as well as a prolonged average life at the level of his receptor and, in addition, some theoretical advantages among others calcium antagonists, improvements on the renal function by reducing the intraglomerular pressure and microalbuminuria. Nevertheless, the clinical evaluation of these last properties still depends on the results derived from clinical trials. Besides to go deep in its role in their antihypertensive effect, we presented a brief review on new cardiometabolic aspects of these dihydropyridines calcium antagonists focusing in manidipine.

[Genetic diagnosis of autosomal dominant polycystic kidney disease using multiplex-PCR]. / Diagnóstico genético de poliquistosis renal autosómica dominante mediante PCR múltiple.

BACKGROUND: Autosomal Dominant Polycystic Kidney Disease (ADPKD) is the most common life-threatening hereditary disease. Molecular analysis with highly polymorphic short tandem repeats, located in the vicinity of the two genes responsible for the disease (PKD1 and PKD2), is used to confirm diagnosis and give genetic counseling to members of affected families. METHODS: We have developed a new assay to genotype five PKD1 and four PKD2 markers, based on two multiplex PCR reactions, and capillary electrophoresis analysis. A total of 110 subjects, belonging to 14 affected families, were genotyped to confirm the concordance with the singleplex method used previously. RESULTS: The amplicons ranged from 95 to 154 bp in length, and complete STR profiles were obtained from 1-5 ng DNA. The specificity of the multiplex PCR system was 88,5% (95%CI= 75,9-95,2), and the sensitivity, 87,9 (95%CI= 76,1-94,6). CONCLUSIONS: This is a useful strategy that, together with automated computer-based allele detection, allows reliable, simple, faster, and cheaper genetic analysis than the previous singleplex method.

Pancreatic Cancer Incidence, Mortality, and Survival in Puerto Rico, 2001-2015.

OBJECTIVE: To perform an epidemiologic profile of pancreatic cancer (PC) in Puerto Rico (PR) with data gathered from 2001 to 2015. METHODS: Using data from the PR Central Cancer Registry we estimated incidence and mortality rates and trends of PC in PR, and performed survival analyses. We also compared the age-standardized incidence and mortality rates of PC in people in PR with those of Hispanics, non-Hispanic whites, and non Hispanic blacks in the United States (US). RESULTS: From 2011 to 2015, 7.8 per 100,000 persons were diagnosed with PC in PR; higher rates were observed in men than in women (9.2 vs. 6.7 per 100,000, respectively) and in persons 65 years old and older (42.7 per 100,000 persons). For the same period, 6.7 per 100,000 persons died from PC; men and persons 65 years and older had higher mortality rates. Incidence and mortality trends of PC in PR increased from 2001-2015 (annual percent change [APC] = 3.8% and 1.9%, respectively (p<0.05). Lower risk of being diagnosed with and dying from PC was seen in PR than in members of several racial/ethnic groups in the US. The median survival time for PC cases diagnosed in PR during the period of 2008 to 2012 was 5.3 months. CONCLUSION: We observed increasing mortality rates and low survival in PC patients in PR. Research on access and response to treatment is needed to elucidate the reasons for the observed results and have a positive impact on PC burden and survival.

Epidemiology of Pancreatic Cancer in Puerto Rico (1987-2010): Incidence, Mortality and Survival.

BACKGROUND & OBJECTIVE: Pancreatic cancer is an uncommon type of cancer worldwide. Nonetheless, even with early diagnosis, mortality rates are high. This study aims to perform an epidemiologic profile of pancreatic cancer in Puerto Rico (PR) from 1987-2010. METHODS: Using data from the Puerto Rico Central Cancer Registry, age-standardized incidence and mortality rates of pancreatic cancer in PR were compared with Hispanics, non-Hispanic Whites, and non-Hispanic Blacks in the United States of America (USA). Incidence and mortality trends of pancreatic cancer were estimated, and survival analyses were also performed. RESULTS: In 2005-2010, 5.8 per 100,000 persons were diagnosed with pancreatic cancer in PR and mortality rates were similar. Pancreatic cancer was more frequent in men (6.5 per 100,000 men) than women (5.2 per 100,000 women), and in persons older than 65 years (32.0 per 100,000 persons). Moreover, the median survival for the people diagnosed with pancreatic cancer in PR during 2006-2007 was 4 months and at the end of the third year after diagnosis, only 13% of the patients survived. Incidence trends of pancreatic cancer showed an increase for men (APC=13.0%, p<0.05) from 2006 to 2010, but not for women (APC=-0.4, p>0.05). However, mortality trends showed a slight decrease for men (APC=-1.0%, p<0.05), but not for women (APC=1.4, p>0.05) in the period of 1987 to 2010. Meanwhile, Puerto Ricans in comparison to other racial/ethnic groups living in the USA showed a lower risk for being diagnosed and of dying from pancreatic cancer. CONCLUSION: Our results highlight the need for additional research in pancreatic cancer, in order to have an impact in disease survival in PR.

Measuring chronic rheumatic pain in Mexican Americans: cross-cultural adaptation of the McGill Pain Questionnaire.

We performed a cross-cultural adaptation of the McGill Pain Questionnaire (MPQ) from English to Spanish for studying Mexican Americans in South Texas. Each of the 78 single-word pain descriptors in the original MPQ was translated into Spanish by a panel of nine bilingual health researchers, preserving the original structure of the questionnaire. The pain-intensity content (PIC) of the words in each language was then rated on a 100 mm visual analog scale by 8 bilingual health care providers and 10 bilingual health-care consumers. The correlation between Spanish and English average PIC ratings was strong (r = 0.85 for providers, r = 0.80 for consumers). The translated Spanish version was compared to the original English in a group of 50 bilingual Mexican-American patients with musculoskeletal pain, who completed the MPQ in both languages. There was no difference in Average Pain Rating Index between the Spanish and English versions (29.8 +/- 14.7 vs 29.1 +/- 15.8, p = 0.55), and agreement between the two language versions was almost perfect (ri = 0.85). Test-retest reliability was measured in two groups of hospitalized patients (25 per group), one composed of monolingual Spanish speakers and the other of monolingual English speakers. Each subject completed the MPQ, the McGill Pain Map, two 10-cm visual analog scales measuring pain now and within the past week, the bodily pain items of the MOS-SF36 survey, and the Modified Health Assessment Questionnaire, on two occasions one day apart. Test-retest reliability of the Spanish and English components of the MPQ was not significantly different and was comparable to that of the other pain and health status instruments. We conclude that the Spanish MPQ is cross-culturally equivalent to the original English and has similar concurrent validity and reliability. This questionnaire is suitable for cross-cultural studies of pain comparing Spanish-speaking Mexican Americans with English-speaking members of the same and other ethnic groups.

Interpersonal behavior and resting blood pressure in college women: a daily monitoring study.

UNLABELLED: Psychological factors have long been implicated in the development of hypertension. Most studies exploring this relationship employed questionnaires administered on only one occasion. OBJECTIVE: to evaluate the relation between blood pressure and social behavior in the natural environment over an extended period of time. METHOD: 40 healthy young adult women at varying risk for hypertension were asked to record their behavior and affect following social interactions, three times a day for 32 days. Behaviors were representative of the interpersonal circumplex: dominance, submissiveness, agreeableness, and quarrelsomeness. RESULTS: Casual blood pressure was significantly correlated with submissive behavior (r=.45, P<.05) and inversely correlated with agreeable behavior (r=-.35, P<.05). ANOVAs confirmed these findings and further revealed that offspring of hypertensives with relatively elevated blood pressure were most quarrelsome. CONCLUSION: These results concur with the literature on the relationship between hostility and blood pressure but also suggest the importance of submissiveness in college women.

Risk for hypertension and diminished pain sensitivity in women: autonomic and daily correlates.

Research suggests an association between risk for hypertension and decreased pain sensitivity. However, few studies have utilized non-behavioral indices of pain to corroborate subjective reports or sought to generalize these findings to women. Furthermore, it has not been established whether results obtained using well-controlled laboratory pain stimuli extend to naturalistic pain. In Study 1, 80 young adult women with (N = 40) and without (N = 40) a parental history of hypertension and with either normatively low or high resting systolic blood pressure (SBP) were exposed to two experimental pain stimuli, finger pressure and the cold pressor test. In addition to behavioral pain measures, respiratory sinus arrhythmia (RSA) reactions to pain were also assessed. Women with a parental history of hypertension and/or normatively high resting SBP experienced significantly less pain, as assessed by both behavioral and RSA measures. In Study 2, 37 of the participants from Study 1 monitored their behaviors, affect, and physical symptoms, three times a day for 32 days. Laboratory pain sensitivity was significantly correlated with daily reports of pain but not gastrointestinal symptoms. The present results confirm an association between risk for hypertension and hypoalgesia in women and suggest generalizability of this relationship to everyday life.

Thyrotropin-like immunoreactivity in the developing chicken retina.

In this paper we analysed the presence and localisation of thyrotropin during retinal development in Gallus domesticus. Specific thyrotropin-like immunohistochemical staining was observed from the beginning of the second incubation week to one day post-hatching in chicken retina. Thyrotropin is a 28.3 KDa glycoprotein, synthesised by the anterior pituitary gland, and it is implicated in the stimulation of the synthesis and release of thyroid hormones. Until now, the action of thyrotropin has been established exclusively in hormonal terms. Recently, this glycoprotein has been localised in synaptic processes in the human retina by using a specific antiserum (Fdez-Trujillo et al., 1995). To the best of our knowledge this report is the first time that thyrotropin has been immunocytochemically demonstrated in the chicken retina. The pattern of thyrotropin-like immunoreactivity suggests that this glycoprotein could act as modulator of synaptic transmission, but it may also play a much broader role in regulating trophic functions.

[Granulocytic sarcoma (chloroma) of small bowel: an unfrequent cause of intestinal obstruction]. / Sarcoma granulocítico (cloroma) del intestino delgado: una causa infrecuente de suboclusión intestinal.

Granulocytic sarcoma or chloroma is a malignant extra medullar tumor, based on inmature myeloid cells. It usually emerges as a secondary manifestation of acute myeloid leukemia. Chloromas are scarcely diagnosed in patiens without hematological malignances, either peripheral or medullar, and are thus frequently misdiagnosed for other tumors. In these patients, further development of acute leukemia seems to stand as a rule. Small bowel location of these tumors has hardly been reported. A case of granulocytic sarcoma in a non-leukemic at time of diagnosis patient is reported therein. Medical literature is briefly reviewed.

[Identification and typification of the human papilloma virus in women using the "Timely Detection of Cancer" program in Durango, Mexico]. / Identificación y tipificación del virus del papiloma humano en mujeres usuarias del programa "Detección Oportuna de Cáncer" en Durango, México.

OBJECTIVE: In Mexico, the cervical carcinoma is a public health problem, representing more of 36% of the neoplasms. This carcinoma has been etiologically associated with the human papillomavirus (HPV) infection and the polymerase chain reaction (PCR) has been considered as one of the most sensitive methods for its detection. The aim of this study was to determine the HPV types by PCR-RFLPs in 111 women attending in the DOC programs in Gomez Palacio, Durango. METHODS: DNA was extracted from cervix-vaginal samples as previously described and HPV were detectad using the primers MY09 and MY11. Viral type was determined according to analysis RFLPs. RESULTS: The cito-histopatologic diagnoses showed that 93 women did not present cervical alteration: 91 (91.85%) were negative HPV and two (2.15%) were VPH positive (low risk). In contrast, 18 women showed cervical alterations; 17 (94.44%) were VPH positive (11 of low risk and 6 of high risk) and only one did not present HPV infection. CONCLUSION: The distribution of types HPV observed in Gomez Palacio, Durango is according to previous study. This is essential a estimation in the development of strategies for prevention of cervical carcinoma in our region.

Vascular and metabolic properties of manidipine.

The combination of renin-angiotensin system blockers with calcium channel blockers appears to be one of the most effective options for treating hypertension and diabetes.Nevertheless, not all calcium blockers behave in the same manner. Manidipine, unlike other third-generation dihydropyridine derived drugs, blocks T-type calcium channels present in the efferent glomerular arterioles, reducing intraglomerular pressure and microalbuminuria. In addition,T-type channels are related to proliferation, inflammation,fibrosis, vasoconstriction and activation of the renin-angiotensin system. The inhibition of these factors could explain the non-haemodynamic effects of manidipine as compared to other blockers.

Psychonephrology: psychological aspects in autosomal dominant polycystic kidney disease.

The biological, physical and psychological burden of a chronic disease has an impact on the quality of life of people who suffer from it. The perception of quality of life is affected by psychological disorders such as anxiety and depression that have a high prevalence in people with chronic kidney disease (CKD). These factors are also linked to lower life expectancy. It is therefore surprising that the psychological aspects of people with autosomal dominant polycystic kidney disease (ADPKD) have received so little attention in the medical literature, despite their importance for the overall health of these patients. The relatively new discipline called psychonephrology provides a broader view of the impact that these aspects have on individuals with chronic kidney disease, with a consequent practical application. In this article, we examine the consequences and prevalence of psychological problems that can be related to CKD and ADPKD. Firstly, we will focus on the field of CKD and ADPKD within the scope of psychonephrology. Secondly, the article introduces the concept of quality of life as a basic pillar of health that is affected when a person is diagnosed with CKD. Thirdly, we will present a summary of the main research related to anxiety and depression disorders in CKD and ADPKD. The article will conclude by synthesising findings from the different lines of research undertaken.
