RESUMO

BACKGROUND: In addition to increased cardiovascular risk, patients with primary aldosteronism (PA) also suffer from impaired health-related quality of life (HRQoL) and psychological symptoms. We assessed for changes in HRQoL and depressive symptoms in a cohort of Asian patients with PA, after surgical and medical therapy. METHODS: Thirty-four patients with PA were prospectively recruited and completed questionnaires from 2017 to 2020. HRQoL was assessed using RAND-36 and EQ-5D-3L, and depressive symptoms were assessed using Beck Depression Inventory (BDI-II) at baseline, 6 months, and 1 year post-treatment. RESULTS: At 1 year post-treatment, significant improvement was observed in both physical and mental summative scores of RAND-36, +3.65, P = 0.023, and +3.41, P = 0.033, respectively, as well as four subscale domains (physical functioning, bodily pain, role emotional, and mental health). Significant improvement was also seen in EQ-5D dimension of anxiety/depression at 1 year post-treatment. Patients treated with surgery (n = 21) had significant improvement in EQ-5D index score post-treatment and better EQ-5D outcomes compared to the medical group (n = 13) at 1 year post-treatment. 37.9, 41.6 and 58.6% of patients had symptoms in the cognitive, affective and somatic domains of BDI-II, respectively. There was a significant improvement in the affective domain of BDI-II at 1 year post-treatment. CONCLUSION: Both surgical and medical therapy improve HRQoL and psychological symptoms in patients with PA, with surgery providing better outcomes. This highlights the importance of early diagnosis, accurate subtyping and appropriate treatment of PA.

RESUMO

OBJECTIVE: Prediction models have been developed to predict either unilateral or bilateral primary aldosteronism, and these have not been validated externally. We aimed to develop a simplified score to predict both subtypes and validate this externally. METHODS: Our development cohort was taken from 165 patients who underwent adrenal vein sampling (AVS) in two Asian tertiary centres. Unilateral disease was determined using both AVS and postoperative outcome. Multivariable analysis was used to construct prediction models. We validated our tool in a European cohort of 97 patients enrolled in the SPARTACUS trial who underwent AVS. Previously published prediction models were also tested in our cohorts. RESULTS: Backward stepwise logistic regression analysis yielded a final tool using baseline aldosterone-to-lowest-potassium ratio (APR, ng/dl/mmol/l), with an area under receiver-operating characteristic curve of 0.80 (95% CI 0.70-0.89). In the Asian development cohort, probability of bilateral disease was 90.0% (with APR <5) and probability of unilateral disease was 91.4% (with APR >15). Similar results were seen in the European validation cohort. Combining both cohorts, probability of bilateral disease was 76.7% (with APR <5), and probability for unilateral was 91.7% (with APR >15). Other models had similar predictive ability but required more variables, and were less sensitive for identifying bilateral PA. CONCLUSION: The novel aldosterone-to-lowest-potassium ratio is a convenient score to guide clinicians and patients of various ethnicities on the probability of primary aldosteronism subtype. Using APR to identify patients more likely to benefit from AVS may be a cost-effective strategy to manage this common condition.

RESUMO

OBJECTIVE: To develop a primary aldosteronism (PA) disease-specific Health-Related Quality of Life (HRQoL) questionnaire. METHODS: We included newly diagnosed patients with PA (n = 26), and patients with PA after adrenalectomy (n = 25) or treated with mineralocorticoid receptor antagonists (n = 25). According to the guidelines for developing HRQoL questionnaires from the European Organization for Research and Treatment of Cancer (EORTC): Phase I: systematic literature review followed by focus group meetings with patients (n = 13) resulting in a list of 94 HRQoL issues. Relevance of issues was rated by 18 other patients and by health care professionals (n = 15), resulting in 30 remaining issues. Phase II: selected issues were converted into questions. Phase III: the provisional questionnaire was pre-tested by a third group of patients (n = 45) who also completed the EORTC core Quality of Life questionnaire (QLQ-C30). Psychometric testing resulted in a final selection of questions with their scale structure. RESULTS: After the collection and selection of HRQoL issues a provisional questionnaire consisting of 30 items was formed. Of these items, 26 could be assigned to one of the four scales 'physical and mental fatigue', 'anxiety and stress', 'fluid balance' and 'other complaints' cumulatively accounting for 68% of variation in all items. All scales had good reliability and validity. There was a significant correlation of all four scales with the QLQ-C30 in most cases. CONCLUSIONS: We developed the first PA-specific HRQoL questionnaire (PA-QoL) using standard, methodologically proven guidelines. After completion of the final validation (phase IV, international field testing), the questionnaire can be implemented into clinical practice.

RESUMO

OBJECTIVE: To develop a prediction model to confirm or exclude primary aldosteronism (PA) in patients with an inconclusive salt loading test (SLT). CONTEXT: Diagnosis in patients with a suspicion of PA can be confirmed using an SLT. In case of inconclusive test results the decision about how to manage the patient is usually based on contextual clinical data. DESIGN: We included a retrospective cohort of 276 patients in the final analysis. METHODS: All patients underwent an SLT between 2005 and 2016 in our university medical center. The SLT was inconclusive (post-infusion aldosterone levels 140-280 pmol/L) in 115 patients. An expert panel then used contextual clinical data to diagnose PA in 45 of them. Together with 101 patients with a positive SLT this resulted in a total of 146 patients with PA. A total of 11 variables were used in a multivariable logistic regression analysis. We assessed internal validity by bootstrapping techniques. RESULTS: The following variables were independently associated with PA: more intense potassium supplementation, lower plasma potassium concentration, lower plasma renin concentration before SLT and higher plasma aldosterone concentration after SLT. The resulting prediction model had a sensitivity of 84.4% and a specificity of 94.3% in patients with an inconclusive SLT. The positive and negative predictive values were 90.5 and 90.4%, respectively. CONCLUSIONS: We developed a prediction model for the diagnosis of PA in patients with an inconclusive SLT that results in a diagnosis that was in high agreement with that of an expert panel.

RESUMO

Primary aldosteronism (PA) is an increasingly identified cause of secondary hypertension. PA can be caused by an aldosterone-producing adenoma or by bilateral adrenal hyperplasia, generally treated by adrenalectomy or mineralocorticoid receptor antagonists, respectively. Recent studies suggest that PA is associated with more psychological symptoms and lower levels of well-being. The purpose of this study was to investigate the associations between subtype of PA and psychological symptoms and well-being after specific treatment. We analyzed the outcomes of the Mental Health Continuum-Short Form and the Symptom Checklist in 160 patients (mean age 57 years; 74.3% males) with PA, comparing the scores for psychological symptoms and well-being between both subtypes of PA. Additionally, we performed subgroup analyses based on gender, age, time since initiation of treatment, and co-morbidity. Moreover, we compared the results with published norm scores. Mean follow-up after adrenalectomy or start of medication was four years and two months. Depressive symptoms, anxiety and obsessive-compulsive thoughts and well-being did not differ between subtypes of PA. Subgroup analysis did not reveal any differences, except for women with bilateral adrenal hyperplasia who scored higher on the anxiety subscale than women after adrenalectomy. Compared to the general population, patients with treated PA reported more psychological symptoms. In contrast, well-being did not differ significantly from norm scores. Subtype and treatment of PA were no important determinants of psychological symptoms and well-being on the long-term. We suggest that physicians should be alert for psychological symptoms, as these were more frequently present in patients with PA.

RESUMO

Context: In primary aldosteronism (PA), two subtypes are distinguished: aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (BAH). In general, these are treated by adrenalectomy (ADX) and mineralocorticoid receptor antagonists (MRA), respectively. Objective: To compare the effects of surgical treatment and medical treatment on quality of life (QoL). Design: Post hoc comparative effectiveness study within the Subtyping Primary Aldosteronism: A Randomized Trial Comparing Adrenal Vein Sampling and Computed Tomography Scan (SPARTACUS) trial. Setting: Twelve Dutch hospitals and one Polish hospital. Participants: Patients with PA (n = 184). Interventions: ADX or MRAs. Main Outcome Measures: At baseline and 6-month and 1-year follow-up, we assessed QoL by two validated questionnaires: RAND 36-Item Health Survey 1.0 (RAND SF-36) and European Quality of Life-5 Dimensions (EQ-5D). Results: At baseline, seven of eight RAND SF-36 subscales and both summary scores, as well as three of five EQ-5D dimensions and the visual analog scale, were lower in patients with PA compared with the general population, especially in women. The beneficial effects of ADX were larger than for MRAs for seven RAND SF-36 subscales, both summary scores, and health change. For the EQ-5D, we detected a difference in favor of ADX in two dimensions and the visual analog scale. Most differences in QoL between both treatments exceeded the minimally clinically important difference. After 1 year, almost all QoL measures had normalized for adrenalectomized patients. For patients on medical treatment, most QoL measures had improved but not all to the level of the general population. Conclusion: Both treatments improve QoL in PA, underscoring the importance of identifying these patients. QoL improved more after ADX for suspected APA than after initiation of medical treatment for suspected BAH.

RESUMO

The aim of this review was to determine the impact of primary aldosteronism on health-related quality of life (HRQoL) and mental health. We performed a systematic literature search up to July 2017 in six electronic databases. First, we screened the articles derived from this search based on title and abstract. Second, the selected studies were systematically reviewed and checked for our predefined inclusion criteria. The search yielded 753 articles, of which 15 studies met our inclusion criteria. Untreated patients with primary aldosteronism showed an impaired physical and mental HRQoL as compared to the general population. Multiple domains of HRQoL were affected. This applied to patients with both an aldosterone-producing adenoma and bilateral adrenal hyperplasia. Adrenalectomy improves HRQoL. Conflicting results have been reported on the extent of this improvement, the improvement after initiation of medical treatment, and whether there is a difference in HRQoL after both treatments. Similarly, psychopathological symptoms of anxiety, demoralization, stress, depression and nervousness were more frequently reported in untreated patients with primary aldosteronism than in the general population and patients with hypertension. Also an impaired sleep quality has been reported. Improvement of these symptoms was observed after treatment with both adrenalectomy and mineralocorticoid receptor antagonists. This review shows that HRQoL is impaired and psychopathology is more frequently reported in patients with primary aldosteronism. This seems to be at least partly reversible after treatment but the extent of improvement remains unknown. To assess HRQoL in these patients more precisely a primary aldosteronism-specific HRQoL questionnaire is required.

RESUMO

BACKGROUND: The distinction between unilateral aldosterone-producing adenoma or bilateral adrenal hyperplasia as causes of primary aldosteronism is usually made by adrenal CT or by adrenal vein sampling (AVS). Whether CT or AVS represents the best test for diagnosis remains unknown. We aimed to compare the outcome of CT-based management with AVS-based management for patients with primary aldosteronism. METHODS: In a randomised controlled trial, we randomly assigned patients with aldosteronism to undergo either adrenal CT or AVS to determine the presence of aldosterone-producing adenoma (with subsequent treatment consisting of adrenalectomy) or bilateral adrenal hyperplasia (subsequent treatment with mineralocorticoid receptor antagonists). The primary endpoint was the intensity of drug treatment for obtaining target blood pressure after 1 year of follow-up, in the intention-to-diagnose population. Intensity of drug treatment was expressed as daily defined doses. Key secondary endpoints included biochemical outcome in patients who received adrenalectomy, health-related quality of life, cost-effectiveness, and adverse events. This trial is registered with ClinicalTrials.gov, number NCT01096654. FINDINGS: We recruited 200 patients between July 6, 2010, and May 30, 2013. Of the 184 patients that completed follow-up, 92 received CT-based treatment (46 adrenalectomy and 46 mineralocorticoid receptor antagonist) and 92 received AVS-based treatment (46 adrenalectomy and 46 mineralocorticoid receptor antagonist). We found no differences in the intensity of antihypertensive medication required to control blood pressure between patients with CT-based treatment and those with AVS-based treatment (median daily defined doses 3·0 [IQR 1·0-5·0] vs 3·0 [1·1-5·9], p=0·52; median number of drugs 2 [IQR 1-3] vs 2 [1-3], p=0·87). Target blood pressure was reached in 39 (42%) patients and 41 (45%) patients, respectively (p=0·82). On secondary endpoints we found no differences in health-related quality of life (median RAND-36 physical scores 52·7 [IQR 43·9-56·8] vs 53·2 [44·0-56·8], p=0·83; RAND-36 mental scores 49·8 [43·1-54·6] vs 52·7 [44·9-55·5], p=0·17) for CT-based and AVS-based treatment. Biochemically, 37 (80%) of patients with CT-based adrenalectomy and 41 (89%) of those with AVS-based adrenalectomy had resolved hyperaldosteronism (p=0·25). A non-significant mean difference of 0·05 (95% CI -0·04 to 0·13) in quality-adjusted life-years (QALYs) was found to the advantage of the AVS group, associated with a significant increase in mean health-care costs of €2285 per patient (95% CI 1323-3248). At a willingness-to-pay value of €30 000 per QALY, the probability that AVS compared with CT constitutes an efficient use of health-care resources in the diagnostic work-up of patients with primary aldosteronism is less than 0·2. There was no difference in adverse events between groups (159 events of which nine were serious vs 187 events of which 12 were serious) for CT-based and AVS-based treatment. INTERPRETATION: Treatment of primary aldosteronism based on CT or AVS did not show significant differences in intensity of antihypertensive medication or clinical benefits for patients after 1 year of follow-up. This finding challenges the current recommendation to perform AVS in all patients with primary aldosteronism.

RESUMO

Phenylketonuria (PKU) is caused by a deficiency or inactivity of the enzyme phenylalanine hydroxylase that converts phenylalanine (Phe) to tyrosine (Tyr). It has been proposed that a reduction of brain Tyr levels, as well as reduced activity of the key regulatory enzyme of dopamine (DA) synthesis tyrosine hydroxylase, leads to a depletion in DA activity in patients with PKU. We report a case of a 56-year-old woman with an intellectual disability due to late diagnosis of PKU and parkinsonism, with a modest clinical response to levodopa therapy.We hypothesize that the signs of parkinsonism might be caused by the depletion of DA activity in the brain. Clinicians should be alert on parkinsonian symptoms in patients with PKU, particularly in those treated with agents that negatively influence DA transmission.

RESUMO

BACKGROUND: Psoriasis is a common skin disease that can also involve the nails. All parts of the nail and surrounding structures can become affected. The incidence of nail involvement increases with duration of psoriasis. Although it is difficult to treat psoriatic nails, the condition may respond to therapy. OBJECTIVES: To assess evidence for the efficacy and safety of the treatments for nail psoriasis. SEARCH METHODS: We searched the following databases up to March 2012: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, MEDLINE (from 1946), EMBASE (from 1974), and LILACS (from 1982). We also searched trials databases and checked the reference lists of retrieved studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA: All RCTs of any design concerning interventions for nail psoriasis. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial risk of bias and extracted the data. We collected adverse effects from the included studies.   MAIN RESULTS: We included 18 studies involving 1266 participants. We were not able to pool due to the heterogeneity of many of the studies.Our primary outcomes were 'Global improvement of nail psoriasis as rated by a clinician', 'Improvement of nail psoriasis scores (NAS, NAPSI)', 'Improvement of nail psoriasis in the participant's opinion'. Our secondary outcomes were 'Adverse effects (and serious adverse effects)'; 'Effects on quality of life'; and 'Improvement in nail features, pain score, nail thickness, thickness of subungual hyperkeratosis, number of affected nails, and nail growth'. We assessed short-term (3 to 6 months), medium-term (6 to 12 months), and long-term (> 12 months) treatments separately if possible.Two systemic biologic studies and three radiotherapy studies reported significant results for our first two primary outcomes. Infliximab 5 mg/kg showed 57.2% nail score improvement versus -4.1% for placebo (P < 0.001); golimumab 50 mg and 100 mg showed 33% and 54% improvement, respectively, versus 0% for placebo (P < 0.001), both after medium-term treatment. Infliximab and golimumab also showed significant results after short-term treatment. From the 3 radiotherapy studies, only the superficial radiotherapy (SRT) study showed 20% versus 0% nail score improvement (P = 0.03) after short-term treatment.Studies with ciclosporin, methotrexate, and ustekinumab were not significantly better than their respective comparators: etretinate, ciclosporin, and placebo. Nor were studies with topical interventions (5-fluorouracil 1% in Belanyx® lotion, tazarotene 0.1% cream, calcipotriol 50 ug/g, calcipotriol 0.005%) better than their respective comparators: Belanyx® lotion, clobetasol propionate, betamethasone dipropionate with salicylic acid, or betamethasone dipropionate.Of our secondary outcomes, not all included studies reported adverse events; those that did only reported mild adverse effects, and there were more in studies with systemic interventions. Only one study reported the effect on quality of life, and two studies reported nail improvement only per feature. AUTHORS' CONCLUSIONS: Infliximab, golimumab, SRT, grenz rays, and electron beam caused significant nail improvement compared to the comparative treatment. Although the quality of trials was generally poor, this review may have some implications for clinical practice.Although powerful systemic treatments have been shown to be beneficial, they may have serious adverse effects. So they are not a realistic option for people troubled with nail psoriasis, unless the patient is prescribed these systemic treatments because of cutaneous psoriasis or psoriatic arthritis or the nail psoriasis is severe, refractory to other treatments, or has a major impact on the person's quality of life. Because of their design and timescale, RCTs generally do not pick up serious side-effects. This review reported only mild adverse effects, recorded mainly for systemic treatments. Radiotherapy for psoriasis is not used in common practice. The evidence for the use of topical treatments is inconclusive and of poor quality; however, this does not imply that they do not work.Future trials need to be rigorous in design, with adequate reporting. Trials should correctly describe the participants' characteristics and diagnostic features, use standard validated nail scores and participant-reported outcomes, be long enough to report efficacy and safety, and include details of effects on nail features.

RESUMO

PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) is a widespread disease with high morbidity rates. Advanced stages can be complicated by unintentional weight loss and muscle wasting, which may contribute to increased morbidity and mortality. Reversal of weight loss increases muscle strength and exercise capacity and improves survival. This can partly be achieved by nutritional support, preferably combined with increase in exercise. Androgenic anabolic steroids (AASs), of which testosterone is the parent hormone, increase muscle size and strength. Due to these anabolic effects, AASs may emerge as a treatment option in COPD patients suffering from muscle wasting. RECENT FINDINGS: Seven trials investigated the effects of AAS in patients with COPD. Some studies also included nutritional therapy and/or a pulmonary rehabilitation program. Compared with placebo, AASs increase lean body mass (LBM) and muscle size. However, no consistent effects on muscle strength, exercise capacity, or pulmonary function are seen. SUMMARY: AASs increase LBM in patients with advanced stages of COPD. No consistent beneficial effect on other endpoints was demonstrated in the reviewed trials. However, probably higher doses of AASs are needed to exert a clinically meaningful effect on muscle strength or exercise capacity. Currently, no evidence is available to recommend AASs to all patients with COPD. In individual cases, treatment with AASs can be considered, particularly in men with advanced COPD, moderate-to-severe functional impairment, muscle wasting and on chronic corticosteroid therapy. Treatment with AASs should preferably be combined with a rehabilitation program and nutritional support. AASs should not be used in women or in men with symptomatic heart disease. When treatment with AASs is considered, intramuscular nandrolone-decanoate is preferred in a dose of 50-200 mg per week for a period of 12 weeks. However, the efficacy of AAS treatment in COPD patients needs further clarification in well designed, adequately powered clinical studies.

RESUMO

Occult hepatitis B virus (HBV) is defined by the presence of plasma HBV DNA in individuals with HBV core antibodies (anti-HBc), but without HBV surface antigen (HBsAg). The prevalence of occult HBV in HIV-infected patients remains controversial, and the risk factors, clinical significance and effect of highly active antiretroviral therapy (HAART) are unknown. The aim of this study was to determine prevalence, risk factors, and clinical significance of occult HBV in HIV-infected patients and to evaluate the effect of HAART. Plasma HBV DNA levels were determined in 191 HIV positive, antiretroviral naïve patients, who were anti-HBc positive and HBsAg negative. Quantitative HBV DNA was determined using a Taqman real-time nested PCR. Additionally, plasma HIV RNA levels, CD4 cell counts, anti-HBs-antibodies, anti-HCV-antibodies, ALT, AST, and gammaGT were determined. Occult HBV (a plasma HBV DNA level >50 copies/ml) was detected in 9/191 (4.7%) of the patients. Among 45 anti-HBs-negative patients (isolated anti-HBc positive), the prevalence was 11.1%. Patients with occult HBV had significantly lower CD4 count compared to anti-HBc-positive/HBsAg negative/HBV DNA-negative patients (105 +/- 157 (median +/- SD) vs. 323 +/- 299 cells/mm(3), P = 0.019). When HAART (including lamivudine) was initiated in the patients with occult HBV, HBV DNA was no longer detectable in any of the patients during 3 years of follow-up. In conclusion, occult HBV was associated with low CD4 counts and may be viewed as opportunistic reactivation of HBV that resolves as a consequence of HAART induced immune reconstitution and/or the effect of lamivudine.
