The Influence of Conventional Treatment on Symptoms and Complaints in Patients With Chronic Postsurgical Hypoparathyroidism.

Quality of life (QoL) is impaired in patients with chronic hypoparathyroidism (HypoPT). With a recently developed specific patient questionnaire, the 28-item Hypoparathyroid Patient Questionnaire (HPQ 28), we were able to demonstrate an effect of laboratory parameters on symptoms and complaints identified by scales and items of the HPQ 28. Here, we evaluated the effect of conventional treatment modalities on QoL using this specific questionnaire. In this cross-sectional study, we included 49 HypoPT (41 female and 8 male) patients. Laboratory values of total serum calcium, magnesium, phosphate, calcium-phosphate product (CPP), and 24-hour urine for calcium and phosphate were analyzed. Patients completed the HPQ 28 questionnaire during the corresponding visit. Mean age was 57.3 ± 10.5 years and duration of disease 12.6 ± 9.8 years. Most patients (86%, n = 42) were treated with the active vitamin D analogs calcitriol, alfacalcidol, or dihydrotachysterol (DHT). The use of calcium and magnesium supplements influenced scales on HPQ 28 in a dose-dependent manner. We detected a dose-dependent increase on the HPQ 28 scales "depression and anxiety" and "pain and cramps," and the item "numbness and tingling" related to calcitriol. This effect was independent of gender, age, underlying disease, kind of surgery, serum 25-hydroxyvitamin D3, calcium, or phosphate values. This study presents the first data on specific symptoms of HypoPT patients dependent on different treatment modalities. Our data suggest that in part the reduced QoL in these patients might be caused by conventional treatment. © 2022 The Authors.

Quantification of Symptom Load by a Disease-Specific Questionnaire HPQ 28 and Analysis of Associated Biochemical Parameters in Patients With Postsurgical Hypoparathyroidism.

In hypoparathyroidism (HypoPT), patients suffer severely from reduced quality of life. The complexity of HypoPT demands a disease-specific control instrument to characterize symptom load. We employed a newly developed disease-specific Hypoparathyroid Patient Questionnaire (the HPQ 40/28) to investigate and quantify HypoPT patients' complaints and contributing factors. In this cross-sectional, two-center study, patients with postsurgical HypoPT (n = 49) were matched for gender and age and compared with patients having undergone thyroid surgery without HypoPT (n = 39) and patients with primary hyperparathyroidism (n = 35). The HPQ 40/28 was completed when patients visited the respective center. Clinical background information, blood tests, and current medication were documented by the physician. Serum calcium lay within the reference range in 87% of HypoPT patients, serum phosphate in 95.7%, and calcium-phosphate product (CPP) in 100%. HPQ 40/28 scores for the scales "pain and cramps" (PaC), "neurovegetative symptoms" (NVS), "numbness or tingling," and "heart palpitations" were significantly elevated in comparison with control groups. Correlations between complaints and laboratory parameters could be demonstrated in the HypoPT group, with serum calcium correlating with NVS (r = 0.309, p < 0.05) and serum phosphate with loss of vitality (r = 0.349, p < 0.05). CPP was the main contributor to symptom load with an influence on PaC (r = 0.295, p < 0.05), loss of vitality (r = 0.498, p < 0.001), numbness or tingling (r = 0.328, p < 0.05), and memory problems (r = 0.296, p < 0.05). In conclusion, the newly developed HPQ 40/28 successfully identified and quantified symptoms typical in HypoPT patients. Using the HPQ 40/28, the CPP was identified as the predominant factor in the severity of complaints in HypoPT. © 2020 The Authors.

Standardised patient education in adrenal insufficiency: a prospective multi-centre evaluation.

OBJECTIVE: Patients with adrenal insufficiency (AI) suffer from impaired quality of life and are at risk of adrenal crisis (AC) despite established replacement therapy. Patient education is regarded an important measure for prevention of AC and improvement of AI management. A standardized education programme was elaborated for patients with chronic AI in Germany. DESIGN: Longitudinal, prospective, questionnaire-based, multi-centre study. METHODS: During 2-h sessions, patients (n = 526) were provided with basic knowledge on AI, equipped with emergency cards and sets and trained in self-injection of hydrocortisone. To evaluate the education programme, patients from eight certified centres completed questionnaires before, immediately after and 6-9 months after training. RESULTS: 399 completed data sets were available for analysis. Questionnaire score-values were significantly higher after patient education, indicating successful knowledge transfer (baseline: 17 ± 7.1 of a maximum score of 29; after training: 23 ± 4.2; P < 0.001), and remained stable over 6-9 months. Female sex, younger age and primary cause of AI were associated with higher baseline scores; after education, age, cause of AI and previous adrenal crisis had a significant main effect on scores. 91% of patients would dare performing self-injection after training, compared to 68% at baseline. An improvement of subjective well-being through participation in the education programme was indicated by 95% of the patients 6-9 months after participation. CONCLUSION: Patient group education in chronic AI represents a helpful tool for the guidance of patients, their self-assurance and their knowledge on prevention of adrenal crises. Repeated training and adaptation to specific needs, for example, of older patients is needed.

The HPQ-Development and First Administration of a Questionnaire for Hypoparathyroid Patients.

Hypoparathyroidism patients suffer a variety of complaints often leading to reduced quality of life. Currently, no specific standard instrument exists to measure corresponding disease manifestations. We therefore aimed to develop a disease-characteristic questionnaire for hypoparathyroid patients. We used an analytical-empirical approach for questionnaire construction based on retrospective analysis of four well-established but non-disease-specific questionnaires (Symptom Checklist 90, revised [SCL-90-R]; Giessen Complaint List [GBB]; Short-Form-36 Health Survey [SF-36]; von Zerssen Symptom List [B-L Zerssen]) and two additional unpublished or local questionnaires (SHGdQ and GPQ) in a German hypoparathyroidism self-help group (n = 60). Retrospective data were compared with corresponding general population norms. The new questionnaire was administered prospectively over 1 year to patients with postoperative hypoparathyroidism and two control groups to validate specificity. Exploratory factor analysis (EFA) and reliability testing were applied to identify relevant scales and reduce overlapping items. In the self-help group, SCL-90-R revealed elevated symptom load in four complaint areas (p = 0.003 to p < 0.001). The SF-36 mental summary score (p < 0.001) and further scales were lowered. In the GBB, four of five scales (p = 0.009 to p < 0.001) were elevated. In the B-L Zerssen, 6 of 24 items revealed complaint areas. Based on these findings, the new 40-item "Hypoparathyroid Patient Questionnaire" (HPQ 40) was developed, tested prospectively, and further analyzed. EFA revealed five scales (pain and cramps, gastrointestinal symptoms, depression and anxiety, neurovegetative symptoms, loss of vitality), all with Cronbach's alpha >0.7. The questionnaire was revised accordingly and shortened to 28 questions to avoid redundancy. We present a new disease-characteristic questionnaire for hypoparathyroidism patients. Prospective testing revealed five major complaint areas and promising psychometric properties. This questionnaire can be tested for usefulness in further clinical trials. © 2019 The Authors.

[Hypoparathyroidism - un underestimated problem?] / Hypoparathyreoidismus ­ ein unterschätztes Problem?

BACKGROUND: Hypoparathyroidism is a rare and disabilitating disorder characterized by hypocalcemia and low parathyroid hormone levels. Most of the cases occur as a result of the removal of parathyroid glands or damage to the glands during neck surgery. More rare causes include nonsurgical causes such as autoimmune or genetic diseases. METHOD: In this review, a panel of experts presents the current state of diagnosis and therapy of hypoparathyroidism and explains practical aspects of caring for the affected patients. RESULTS: Common signs and symptoms are abnormal sensations and increased excitability in the lower limbs, paresthesia of perioral areas and nocturnal leg cramps. Renal complications frequently occur, but also basal ganglia calcification. Treatment consists of administration of vitamin D analogs in combination with 0.5-1.0 g calcium daily. An adjunctive treatment with the in April 2017 approved recombinant human parathyroid hormone (1-84) is an option for patients whose hypoparathyroidism is difficult to control by conventional treatment alone. Initially and after dose changes follow-up controls should be performed at least every 2 weeks, in well-controlled patients or in the case of chronic progression every 3-6 months.

Age dependent secretion of LH and ACTH in healthy men and patients with erectile dysfunction.

OBJECTIVES: Age dependent secretion of testicular and adrenal androgens was examined in healthy men and patients with erectile dysfunction (ED). METHODS: In 95 healthy men (age 20-74 years) and 739 patients with ED, luteineizing hormone (LH, n = 739), adrenocorticotropic hormone (ACTH, n = 480) and the secretion products of testis and adrenal gland testosterone (T, n = 750), free testosterone (fT, n = 718), dehydroepiandrosteronesulfate (DHEAS, n = 598) and cortisol (n = 538) were measured. RESULTS: In healthy men, LH was measured from 0.75-8.58 mIU/ml and ACTH from 10.59-121.7 pg/ml. Statistically, age was not correlated to LH (P = 0.573) and ACTH (P = 0.833) in healthy men. The secretion products T (P < 0.05), fT (P < 0.001), DHEAS (P < 0.001) and cortisol (P < 0.05) declined significantly with age in healthy persons. In patients with ED, a significant age dependent increase of LH (P < 0.05, n = 739), but not ACTH (P = 0.469, n = 480) was found. T (P < 0.001, n = 736), fT (P < 0.001, n = 718) and DHEAS (P < 0.001, n = 598), but not cortisol (P = 0.307, n = 538) declined in age dependent patients with ED. Age matching revealed a statistical significant elevation (P < 0.05) only for LH (n = 659) in comparison to healthy men (n = 94), all other hormones were not different in both groups. CONCLUSION: An LH-increase in patients with erectile dysfunction underlines the importance of Leydig cell degeneration in this disease, but age dependent decline of T secretion was comparable to healthy men, demonstrating a working hypophyseal-testicular-axis. Indication of androgen replacement is therefore limited to selected cases.
