Measuring change in dry-mouth symptoms over time using the Xerostomia Inventory

Objective: To examine the responsiveness to change of the Xerostomia Inventory (XI). Background: The XI is an 11‐item summated rating scale which results in a single continuous scale score representing the severity of chronic xerostomia. While the XI has been used as an outcome measure in clinical research, the magnitude of a clinically meaningful change score has yet to be determined. Methods: This study comprises a secondary analysis of data from a longitudinal study of changes in xerostomia symptoms in two groups whose symptom trajectories were likely to differ substantially: the normal group was a convenience sample of asymptomatic middle‐aged and older individuals with otherwise stable perceptions of mouth dryness; and the onset group comprised patients who were about to undergo radiotherapy for head/neck cancer (and would therefore be expected to develop more severe xerostomia after the baseline measurements). Statistical analyses examined cross‐sectional construct validity and internal consistency, test‐retest reliability and the measure's responsiveness and longitudinal construct validity. The mean change scores of those for whom ‘a little’ improvement was reported were used to determine the minimally important difference for the XI. Results: Over two‐thirds of the onset group members reported dry mouth ‘frequently’ or ‘always’ at follow‐up (2 months) and there was a concomitant increase in their mean XI score. Test‐retest reliability was acceptable. Examination of within‐individual change among those who changed and those for whom stability was observed, showed that only those who worsened had significantly greater XI scores at follow‐up. The minimally important difference to reflect deterioration in xerostomia symptoms was determined to be 6 scale points. Between baseline and 2 months, the XI scores of 32 participants (33.7%) deteriorated by the minimally important difference (7.1% and 54.7% respectively among the normal and onset groups; p < 0.0001). Conclusion: The validity and responsiveness of the XI appear to be acceptable, and a change in XI score of 6 or more points is clinically meaningful.     

Prevalence of xerostomia and hyposalivation in the nursing home and the relation with number of prescribed medication

In nursing homes, the number of patients with their own dentition increases. Many of them, however, are unable to perform oral hygiene procedures. Medication is considered to be an important cause of hyposalivation, which may lead to oral alterations and loss of teeth. The aim of the present study was to investigate the prevalence of xerostomia and hyposalivation in a Dutch nursing home and to examine the possible relation with medication usage. Between January and March 2001, the salivary flow rates were measured in 50 patients residing in a nursing home in Amsterdam. Unstimulated saliva, parafilm-stimulated saliva and citric acid stimulated saliva were determined. Xerostomia was determined by the question "My mouth feels dry" and the medication used was examined. The data were analysed with (M)ANOVA. The average age of the patients was 78.1 +/- 9.7 years. Forty-eight % of the patients had an unstimulated flow rate of less then 0.20 ml/min and 24% had a flow rate even lower than 0.10 ml/min (reference values: 0.25-0.50 ml/min). The flow rate of women was significantly lower than that of men (p < 0.01), even after correction for age, smoking and the number of prescribed medications. Salivary flow rates decreased significantly with age (p < 0.05). The number of prescribed medication was significantly higher in patients over the age of 70 (p < 0.01, n = 42) and also in women (p < 0.01). The prevalence of xerostomia was 52% with no difference between men and women. In nursing homes, the prevalence of hyposalivation and xerostomia is high. The number of xerogenic medications used seems to be an important factor. Women and patients aged over the age of 70 years need special attention with respect to oral health.     

Age and medication are significant risk factors for xerostomia in an English population, attending general dental practice

Objective: To study the prevalence of xerostomia in an English population, attending general dental practice and relate it to age. medication and gender. Design Study: Cross‐sectional. Setting: Five General Dental Practices in Merseyside, North of England. Subjects: 1,103 adult patients attending for routine dental care. Intervention : Questionnaire administered by dentists. Main Outcome Measures: Age, gender, systemic medication, reported oral dryness. Results: 1,103 patients (654 females) were recruited, of whom 427 (39%) were aged 60 years or older, 26% of patients reported taking medication. The overall prevalence of xerostomia was 12.7% (males‐10.3%, females 14.4%). Age. medication and female gender were found to be significant risk factors for xerostomia, using logistic regression analysis. Conclusions: The prevalence of xerostomia (12.7%) in an English population was lower than reported in previous North American and Swedish studies. Medication was a significant risk factor for xerostomia and a better predictor of risk status, than either age or gender.     

Self-reported dry mouth in Swedish population samples aged 50, 65 and 75 years

doi: 10.1111/j.1741‐2358.2010.00420.x Self‐reported dry mouth in Swedish population samples aged 50, 65 and 75 years Background: Reduced salivary flow may have a negative impact on general well‐being, quality of life and oral health. Objectives: To examine xerostomia in 50‐, 65‐ and 75‐year‐olds, background factors and effect on Oral Impacts on Daily Performances (OIDP). Methods: In 1992, a questionnaire was sent to all 50‐year‐old persons (n = 8888) in two Swedish counties. In 2007, the same questionnaire was sent to all 65‐year‐olds (n = 8313) in the two counties and to all 75‐year‐olds (n = 5195). Response rate was for the 50, 65 and 75 year olds 71.4, 73.1 and 71.9%, respectively. Results: Xerostomia was higher in women than in men in all age groups. There was higher prevalence of xerostomia with increasing age in both sexes and it was more frequent at night than during daytime. ‘Often mouth dryness’ was 2.6–3.4 times more prevalent in those who reported an impact from OIDP. The highest odd ratios were for daytime xerostomia and for the variables burning mouth (17.1), not feeling healthy (4.5), daily smoking (4.4), and medication (4.1). Conclusions: The dramatic increase of xerostomia between age 50 and 75, especially amongst women, needs to be considered in the management of this age group.     

Treatment compliance or medication adherence in children and adolescents on ADHD medication in clinical practice: results from the COMPLY observational study

Although the efficacy and tolerability of ADHD medications have been investigated fairly extensively, there are very few data comparing the different types of medication (e.g. psychostimulants, non-stimulants) in terms of medication adherence. The primary research objective of the COMPLY observational study was to evaluate medication adherence (i.e. compliance) over 1 year in children and adolescents with ADHD in a routine clinical setting. COMPLY was a prospective 12-month, observational, open-label study that included children and adolescents, aged 6–17 years, with ADHD. Medication adherence (i.e. compliance) was measured using the Pediatric Compliance Self-Rating (PCSR) instrument and using items 1–4 of the Medication Adherence Rating Scale (MARS). A total of 504 patients were enrolled. At baseline, 252 patients (50.0 %) were prescribed non-stimulant (atomoxetine) medication and 247 patients (49.0 %) were prescribed psychostimulant medication. Both types of medication were prescribed concomitantly in five patients (1.0 %). After 12 months, 123 patients (48.8 %) were taking atomoxetine and 176 patients (71.3 %) were taking psychostimulants. Adherence (PCSR score ≥5) was present in both groups (atomoxetine: 67.5 %; psychostimulant: 74.2 %) throughout the observation period. MARS scores declined over time in both groups (atomoxetine: from 3.7 to 2.9; psychostimulant: from 3.6 to 3.1), indicating a deterioration in adherence. There was no statistically significant difference in terms of medication adherence between the two groups.     

Xerostomia in older adults: a longitudinal study

Although xerostomia in older adults has received substantial research attention, there have been few longitudinal studies of non-patient populations. Consequently, little is known about the incidence or course of this condition among this group. This paper reports the results of a longitudinal study designed to address these issues. In 1989, data on xerostomia were collected from 907 randomly-selected community dwelling adults aged 50 years and over. Three years later, 611 (71% of those presumed to be alive) were followed-up and data on xerostomia collected again. At baseline, 15.5% of these 611 subjects reported xerostomia, while at follow-up this had risen to 29.5%. The majority of the latter (115/180) were incident cases, reporting xerostomia only at follow-up, while the remainder were chronic cases, reporting xerostomia at both baseline and follow-up. A crude estimate of the three-year incidence rate was 22.5%. In a logistic regression analysis, three baseline variables were associated with incidence; older subjects, those with one or more chronic medical conditions and those reporting their general health as poor were more likely to develop xerostomia. In a similar analysis, age was the only variable associated with chronicity, with older subjects more likely to be chronic cases. The data also suggest that the onset of xerostomia was associated with an increase in other oral symptoms and problems with eating, communication and social interaction.     

Medication in elderly people: its influence on salivary pattern,signs and symptoms of dry mouth

doi:10.1111/j.1741‐2358.2009.00293.x
Medication in elderly people: its influence on salivary pattern, signs and symptoms of dry mouth Objective: To compare stimulated and non‐stimulated salivary flow, pH, buffering capacity and presence of signs and symptoms of hyposialie and xerostomia in elderly patients, with senile dementia using medication and healthy elderly subjects not using medication. Methods: Forty individuals (mean age: 68.5 years) were divided into two groups, according to the use (G1) or non‐use (G2) of medication and the presence (G1) or absence (G2) of senile dementia. Data with reference to the general health condition, use of medication and the patient’s complaints were collected during anamnesis. Clinical examination identified signs associated with hyposialie and xerostomia. Stimulated and non‐stimulated saliva flow, pH and buffering capacity were verified. Results: The stimulated saliva flow in both groups was below normal parameters. The drugs used by individuals in G1 showed xerostomic potential. Individuals with a higher consumption of xerostomic medication presented with dry and cracked lips. A significant negative relationship was found between drugs consumption and the buffering capacity (p < 0.001), and the resting saliva flow rate (p = 0.002). Conclusion: The use of medication increases the chance that an elderly person may present signs related to xerostomia and alterations in stimulated saliva flow and buffering capacity.     

Evaluation of the efficacy of two mouthrinses formulated for the relief of xerostomia of diverse origin in adult subjects

doi: 10.1111/j.1741‐2358.2012.00626.x Evaluation of the efficacy of two mouthrinses formulated for the relief of xerostomia of diverse origin in adult subjects Objective: To evaluate the efficacy of two new mouthrinses in the reduction of xerostomía‐associated symptomatology. Background: Xerostomia is a common chronic health condition that affects a great number of adults and significantly deteriorates quality of life, such that treatment is necessary. Materials and methods: Sixty‐seven adult subjects of both sexes presenting xerostomia of diverse origin were selected. Mouthrinses were tested using a double‐blind, randomized, cross‐over clinical trial with an intervining wash out period. Results: The 100% of subjects presented sensation of dry mouth, and 86% stated sensation of thick saliva. Burning tongue sensation, need to drink liquids to swallow and the sensation of swallowing difficulty were recorded in more than 50% of the patients. The most frequent pathologies in the sample were depression, arthritis, and arterial hypertension. Results of the clinical tests showed that mouthrinse 1 relieves sensation of dry mouth, need to drink liquids, and swallowing difficulty. In contrast, mouthrinse 2 relieves only latter two symptoms. Both rinses were more effective in relieving xerostomía‐associated symptomatology in patients taking 3 or more medicines simultaneously. Conclusion: Both mouthrinses were effective in relieving various xerostomia symptoms, could be distributed at a low cost, thereby improving the quality of life of population affected.     

Prevalence of oral mucosal lesions in institutionalized elderly people in Mashhad, Northeast Iran

doi: 10.1111/j.1741‐2358.2011.00588.x
Prevalence of oral mucosal lesions in institutionalized elderly people in Mashhad, Northeast Iran Objective: The aim of this study was to determine the prevalence of oral mucosal lesions in institutionalized elderly people in Mashhad, northeast of Iran. Background: This study was conducted to assess the prevalence of oral lesions in the institutionalized elderly. Methods: In this survey, we studied all of the nursing homes in Mashhad; a total of five encompassing 237 residents. The subjects were examined and lesions recorded in a designed checklist. T‐test, chi‐square and Fisher’s exact tests were used for the analysis. Results: The mean age of the patients was 79.59 ± 8.88. Ninety‐eight per cent of cases had at least one oral mucosal lesion. The most common lesions were fissured tongue (66.5%), atrophic glossitis (48.8%), sublingual varicosity (42%) and xerostomia (38%). There was no significant difference in the prevalence of denture‐related lesions (DRLs) between men and women (p > 0.05). Xerostomia was more prevalent in 70–79‐year‐old than in 60–69‐year‐old subjects. No case of oral malignant lesion was detected. Discussion: These findings revealed a higher prevalence of oral mucosal lesions in Mashhad city compared with other studies conducted in other major cities in Iran and abroad. The results emphasise the necessity of national programmes towards oral health promotion.     

Salivary gland hypofunction in elderly patients attending a xerostomia clinic

Objectives: To investigate the aetiological factors and the prevalence of salivary gland hypofunction (SGH) in patients complaining of xerostomia. Design Prospective, clinical study. Setting Xerostomia clinic in the Department of Oral Medicine at Liverpool University Dental Hospital. Subjects 100 consecutive patients, aged 60 years or older, referred for investigation of xerostomia. Interventions Patients were asked specific questions concerning their complaint of oral dryness and associated orofacial symptoms. A detailed medical history was recorded and patients underwent a systematic examination of the head, neck and oral structures. All patients underwent haematological, biochemical, immunological investigations, urinalysis and sialometry. Further investigations and referrals to other specialists were undertaken when appropriate. Main outcome measures The causes of xerostomia were established on the basis of clinical and laboratory findings and SGH was defined as an unstimulated whole salivary flow rate of <0.2ml/min, Results: The causes of xerostomia were identified as: Sjögren's Syndrome (40), iatrogenic (22), psychogenic (14), idiopathic (19), diabetes (1), candidosis (3) and alcohol (1). Sixty five percent of the patients studied had SGH. Conclusions This study has shown that 65% of patients whose presenting complaint was xerostomia had objective evidence of SGH. Several aetiological factors were identified, the most common of which was Sjögren's Syndrome. The possibility of associated systemic diseases should be considered when establishing the aetiology of SGH.     

Changes in Symptoms of Depression With Weight Loss: Results of a Randomized Trial

Recent studies of rimonabant have re‐awakened interest in the possible adverse psychiatric effects of weight loss, as well as of weight loss medications. This study examined changes in symptoms of depression in 194 obese participants (age = 43.7 ± 10.2 years; BMI = 37.6 ± 4.1 kg/m²) in a 1‐year randomized trial of lifestyle modification and medication. Participants were assigned to (i) sibutramine alone; (ii) lifestyle modification alone; (iii) sibutramine plus lifestyle modification (i.e., combined therapy); or (iv) sibutramine plus brief therapy. Participants completed the Beck Depression Inventory‐II (BDI‐II) at baseline and weeks 6, 10, 18, 26, 40, and 52. At 1 year, participants in combined therapy lost the most weight and those in sibutramine alone the least (12.1 ± 8.8% vs. 5.5 ± 6.5%; P < 0.01). Mean BDI‐II scores across all participants declined from 8.1 ± 6.9 to 6.2 ± 7.7 at 1 year (P < 0.001), with no significant differences among groups. Despite this favorable change, 13.9% of participants (across the four groups) reported potentially discernible increases (≥ 5 points on the BDI‐II) in symptoms of depression at week 52. They lost significantly less weight than participants in the rest of the sample (5.4 ± 7.8% vs. 9.0 ± 7.8%, respectively; P < 0.03). The baseline prevalence of suicidal ideation was 3.6%. Seven new cases of suicidal ideation were observed during the year, with three in lifestyle modification alone. Further research is needed to identify characteristics of obese patients at risk of negative mood changes (and suicidal ideation) in response to behavioral and pharmacologic therapies.     

Xerostomia in the Elderly: Prevalence,Diagnosis, Complications and Treatment1

The prevalence of xerostomia was evaluated in 259 volunteers 70 ± 4.5 years old. Seventy–two (27.7%) complained of dry mouth. In 31 (11.8%) salivary secretion was under 0.1 ml/min. The xerostomic patients were compared to an age–matched control group. The main complaints of xerostomia were dry mouth during the day, dry throat, burning sensation of the tongue, difficulty in swallowing, and taste disturbances. Systemic diseases frequent in the xerostomic patients were heart failure and hypertension. Chronic renal failure, depression, rheumatoid arthritis, and hypothyroidism were also encountered. The medications most frequently used by the xerostomic patients were parasympatholytics, sympatholytics, and diuretics. A higher frequency of active caries, gingivitis, and dryness of the mucosa was detected in the xerostomic patients. A significantly higher response to stimulation, elevated salivary calcium, and lowered oral pH were found in this group. Xerostomia was found to be related o t systemic diseases, medications, or a combination of these factors. The importance of saliva for maintaining oral health was also observed. Twenty–nine patients suffering from xerostomia were treated with an artificial saliva. On reexamination after one month, most of them reported improvement, and a significant increase in salivary flow rate was found.     

The Malaysian Medication Adherence Scale (MALMAS): Concurrent Validity Using a Clinical Measure among People with Type 2 Diabetes in Malaysia

Medication non-adherence is a prevalent problem worldwide but up to today, no gold standard is available to assess such behavior. This study was to evaluate the psychometric properties, particularly the concurrent validity of the English version of the Malaysian Medication Adherence Scale (MALMAS) among people with type 2 diabetes in Malaysia. Individuals with type 2 diabetes, aged 21 years and above, using at least one anti-diabetes agent and could communicate in English were recruited. The MALMAS was compared with the 8-item Morisky Medication Adherence Scale (MMAS-8) to assess its convergent validity while concurrent validity was evaluated based on the levels of glycated hemoglobin (HbA1C). Participants answered the MALMAS twice: at baseline and 4 weeks later. The study involved 136 participants. The MALMAS achieved acceptable internal consistency (Cronbach’s alpha=0.565) and stable reliability as the test-retest scores showed fair correlation (Spearman’s rho=0.412). The MALMAS has good correlation with the MMAS-8 (Spearman’s rho=0.715). Participants who were adherent to their anti-diabetes medications had significantly lower median HbA1C values than those who were non-adherence (7.90 versus 8.55%, p=0.032). The odds of participants who were adherent to their medications achieving good glycemic control was 3.36 times (95% confidence interval: 1.09-10.37) of those who were non-adherence. This confirms the concurrent validity of the MALMAS. The sensitivity of the MALMAS was 88.9% while its specificity was 29.6%. The findings of this study further substantiates the reliability and validity of the MALMAS, in particular its concurrent validity and sensitivity for assessing medication adherence of people with type 2 diabetes in Malaysia.     

A reference guide to drugs and dry mouth – 2nd edition

Xerostomia (dry mouth) is an uncomfortable and potentially harmful oral symptom which is usually caused by a decrease in the secretion rate of saliva (salivary gland hypofunction, or SGH). It is more prevalent in the elderly population, primarily due to their increased use of drugs and their susceptibility to disease. Many drugs and drug classes have been linked to xerostomia; the xerogenic effect increases when many drugs are taken concurrently. This Reference Guide to Drugs and Dry Mouth is designed to allow the reader to rapidly identify those pharmacologic agents which have the capacity to induce xerostomia and SGH. Xerogenic drugs can be found in 42 drug categories and 56 sub-categories. A guide to the management of drug-induced SGH and xerostomia is also provided.     

Use of shopping centres in screening for hypertension

In two Edmonton shopping centres 9591 people were screened for hypertension: 3.3% were found to be normotensive but taking antihypertensive medication and another 8.8% were found to have elevated blood pressure. Systolic hypertension alone accounted for 45.3% of the hypertensive cases and diastolic hypertension, with or without systolic, for 54%. Of the group with elevated blood pressure 34.5% had been previously unaware of their condition, 18.7% had never received medication for it, 18.2% had received medication in the past but had discontinued it, 26.1% were still on medication and 2.5% were not taking antihypertensive medication and were uncertain if they had ever done so in the past. Eighty-eight percent of the hypertensives who were receiving no medication went to their physician; 41% were prescribed antihypertensive medication, and 87% were still on treatment three months later and 74% one year after detection. Eighteen percent of those started on treatment had their medication discontinued by their doctor over the next year and 8% stopped treatment on their own. Of those hypertensives already receiving medication 88% went to their doctor and 33% had their medication altered.Physician measurements of blood pressure tended to be lower than those recorded at the screening. At least part of the explanation for this discrepancy is that physicians often used blood pressure cuffs that were too wide for the patient''s arm; 25% of the people screened required cuffs narrower than the standard cuff used by most physicians.The prevalence of hypertension was similar among women taking oral contraceptives and women not taking these agents.     

Adherence to Pharmacotherapy and Medication-Related Beliefs in Patients with Hypertension in Lima,Peru

Objective

To characterize adherence to pharmacological medication and beliefs towards medication in a group of patients with hypertension in a large national hospital.

Materials and Methods

Cross-sectional survey among patients with hypertension attending the outpatient clinic of a large national hospital. Exposure of interest was the patient''s beliefs towards general medication and antihypertensive drugs, i.e. beliefs of harm, overuse, necessity and concern, measured using the Beliefs about Medication questionnaire. Main outcome was adherence measured using the Morisky Medication Adherence Scale-8. Multivariate analysis was conducted using Poisson distribution logistic regression, prevalence ratios and 95% confidence intervals were calculated.

Results

Data from 115 participants, 67% females and mean age 62.7 years were analyzed. Low adherence was found in 57.4%. Highest scores were on the ideas of necessity and one of the most rated statements was “physicians would prescribe less medication if they spent more time with patients”. Beliefs of harm about medications and concerns about antihypertensive drugs were higher in the low adherence group (p<0.01). Those who scored higher on ideas of harm were 52% less likely of being high adherents (PR 0.48; 95% CI 0.25–0.93) and those with higher scores on concerns were 41% less likely of being high adherents (PR 0.59; 95% CI 0.39–0.91). Patients whose ideas of necessity outweighed their concerns were more likely to be adherent (PR 2.65; 95% CI 1.21–5.81).

Conclusions

Low adherence to antihypertensive medication is common. High scores on ideas of harm, concern and a high necessity-concern differential were predictors of medication adherence.     

Determinantes sociales,clínicos y psicosociales asociados a hipertensión arterial no controlada en adultos mayores. Encuesta SABE Colombia 2016

ObjectiveTo evaluate sociodemographic, clinical and psychosocial characteristics that are associated with uncontrolled arterial hypertension (HANC) in older adults in Colombia.MethodsSecondary analysis of data from the National Survey of Health, Welfare and Aging (SABE Colombia 2016), in which men and women aged 60 years or older in the country who were not institutionalized were interviewed. The dependent variable was uncontrolled hypertension (HANC) (≥140/90 mm Hg). The SABE survey surveyed 23694 older adults; 11264 had a diagnosis of arterial hypertension (HTA) and were taking antihypertensive medication. On the other hand, 5106 older adults, randomly selected, had their blood pressure taken. Participants previously diagnosed with HTA under medical management with antihypertensives and who had had their blood pressure taken at the same time were included, resulting in a sample of 2656 participants. Sociodemographic, clinical and psychosocial characteristics were evaluated. Univariate, bivariate, and multivariate analyzes with logistic regression were performed.ResultsOne thousand one hundred eighty-eight (44.7%) participants presented HANC. A higher prevalence of HANC was observed in adults older than 74 years (OR 1.31; 95% CI 1.09-1.57) and lower prevalence in residents of urban areas (OR 0.55; 95% CI 0.42–0.71).ConclusionsAge over 74 years and living in a rural area were identified as variables associated with inadequate blood pressure control in non-institutionalized older adults in Colombia.
