Conversion to neoral for neurotoxicity after primary adult liver transplantation under tacrolimus.

BACKGROUND: Neurological complications after orthotopic liver transplantation (OLTX) have remained a major concern in a small proportion of patients. The etiology of these complications is often thought to be multifactorial: the influence of calcineurin inhibitors is occasionally thought to play an important role. When neurotoxicity occurs after OLTX under tacrolimus, it is usually a minor complication and responds readily to a reduction in the dosage of or a temporary withdrawal of tacrolimus. However, neurotoxic complications occasionally do not respond to this conventional process. Neoral is a microemulsion formulation of cyclosporine. It has more consistent pharmacokinetic parameters and improved bioavailability when compared with conventional cyclosporine. The aim of the present report was to evaluate the role of Neoral in OLTX recipients with neurotoxic complication who failed to respond to a reduction in the dosage of tacrolimus. METHOD: Between August 1995 and November 1997, 330 adults (age >18 years) received primary OLTX under tacrolimus-based immunosuppression (mean age 52.6+/-11.4 years). There were 190 men and 140 women. Twenty-three (7%) patients (mean age 53.2+/-11.8 years; 17 men, 6 women) were converted to Neoral (mean 35+/-41 days after OLTX). These patients were followed until June 1998 (mean follow-up 22.7+/-7.8 months). RESULTS: Four (17.4%) patients died during the follow-up period, and two patients underwent retransplantation. Neurological symptoms improved in all patients who survived. Adequate trough concentrations were achieved in all patients with p.o. Neoral. Nine (39%) patients experienced rejection episodes after conversion. Six (26.1%) patients were converted back to tacrolimus because of ongoing rejection (n=3), retransplantation (n=2), or persistent nausea and vomiting (n=1) without recurrence of the original neurological complication. CONCLUSION: Neurological complications after OLTX disorders that occur under tacrolimus and that fail to respond to a reduction in the dosage can be treated safely by conversion to Neoral. However, the rate of rejection is up to 39%, and patients can often be converted back to tacrolimus without recurrence of the original neurological complication.

Multisomatoform disorder. An alternative to undifferentiated somatoform disorder for the somatizing patient in primary care.

BACKGROUND: For clinical or research use in primary care, the DSM-IV diagnostic criteria for somatization disorder are too restrictive, while the criteria for undifferentiated somatoform disorder are overly inclusive. In this article, we examine the validity of multisomatoform disorder, defined as 3 or more medically unexplained, currently bothersome physical symptoms plus a long (> or = 2 years) history of somatization. METHODS: Data from the Primary Care Evaluation of Mental Disorders Study of 1000 patients from 4 primary care sites were analyzed. The outcomes assessed were 6 domains of health-related quality of life, using the 20-item Short-Form General Health Survey; self-reported disability days and health care use; satisfaction with care; and physician-rated difficulty of the encounter. RESULTS: Multisomatoform disorder was diagnosed in 82 (8.2%) of the 1000 patients who were enrolled in the Primary Care Evaluation of Mental Disorders Study. Compared with mood and anxiety disorders, multisomatoform disorder was associated with comparable impairment in health-related quality of life, more self-reported disability days and clinic visits, and greater clinician-perceived patient difficulty. CONCLUSIONS: Multisomatoform disorder may be a valid diagnosis and potentially more useful than the DSM-IV diagnosis of undifferentiated somatoform disorder. Also, because multisomatoform disorder has a large and independent effect on impairment, its diagnosis should not be precluded simply because of a coexisting mood or anxiety disorder.

Glucocorticoids induce beta2-adrenergic receptor function in human nasal mucosa.

Glucocorticoids are hypothesized to induce beta2-adrenergic receptors (beta2-R) and their functions. The ability of dexamethasone (DEX) in vitro and beclomethasone dipropionate (BDP) in vivo to induce beta2-R messenger RNA (mRNA) and function was investigated in human nasal mucosa. In this tissue, albuterol does not stimulate exocytosis either in vivo or in vitro (Mullol and coworkers, 1992). Therefore, induction of beta2-R-mediated glandular exocytosis by glucocorticoids was proposed as an unambiguous outcome measure. Human nasal mucosa was cultured for 3 d with and without 1 microM DEX, then challenged with media or 100 microM albuterol. Culture supernatants were collected for measurement of exocytosed glandular products. Explant mRNA was extracted for reverse transcriptase-polymerase chain reaction (RT-PCR), and in situ hybridization of beta2-R mRNA performed. In vivo, normal subjects received saline or BDP for 3 d before albuterol nasal provocation. Concentrations of exocytosed products were measured in nasal secretions. RNA was extracted from nasal epithelial scrapings for RT-PCR. In vitro, DEX treatment induced albuterol-mediated glandular exocytosis (p < 0.04), and increased the steady-state beta2-R/beta-actin mRNA ratio (p < 0.05), and expression of beta2-R mRNA in glands. In vivo, BDP increased the beta2-R/beta-actin mRNA ratio in epithelial scrapings (p < 0.04), but did not induce albuterol-mediated glandular secretion. We conclude that glucocorticoids increase steady-state beta2-R mRNA levels in vivo and in vitro, and can induce beta2-R function as assessed by submucosal gland exocytosis in vitro. While topical BDP induced epithelial beta2-R mRNA, it did not modulate exocytosis from the deeper submucosal glands.

The difficult patient: prevalence, psychopathology, and functional impairment.

OBJECTIVE: To determine the proportion of primary care patients who are experienced by their physicians as "difficult," and to assess the association of difficulty with physical and mental disorders, functional impairment, health care utilization, and satisfaction with medical care. DESIGN: Survey. SETTING: Four primary care clinics. PATIENTS: Six-hundred twenty-seven adult patients. MEASUREMENTS: Physician perception of difficulty (Difficult Doctor-Patient Relationship Questionnaire), mental disorders and symptoms (Primary Care Evaluation of Mental Disorders, [PRIME-MDI]), functional status (Medical Outcomes Study Short-Form Health Survey [SF-20]), utilization of and satisfaction with medical care by patient self-report. RESULTS: Physicians rated 96 (15%) of their 627 patients as difficult (site range 11-20%). Difficult patients were much more likely than not-difficult patients to have a mental disorder (67% vs 35% [corrected], p < .0001). Six psychiatric disorders had particularly strong associations with difficulty: multisomatoform disorder (odds ratio [OR] = 12.3. 95% confidence interval [CI] = 5.9-26.8), panic disorder (OR = 6.9, 95% CI = 2.6-18.1), dysthymia (OR = 4.2, 95% CI = 2.0-8.7), generalized anxiety (OR = 3.4, 95% CI = 1.7-7.1), major depressive disorder (OR = 3.0, 95% CI = 1.8-5.3), and probable alcohol abuse or dependence (OR = 2.6, 95% CI = 1.01-6.7). Compared with not-difficult patients, difficult patients had more functional impairment, higher health care utilization, and lower satisfaction with care, whereas demographic characteristics and physical illnesses were not associated with difficulty. The presence of mental disorders accounted for a substantial proportion of the excess functional impairment and dissatisfaction in difficult patients. CONCLUSIONS: Difficult patients are prevalent in primary care settings and have more psychiatric disorders, functional impairment, health care utilization, and dissatisfaction with care. Future studies are needed to determine whether improved diagnosis and management of mental disorders in difficult patients could diminish their excess disability, health care costs, and dissatisfaction with medical care, as well as the physicians experience of difficulty.

Gender, quality of life, and mental disorders in primary care: results from the PRIME-MD 1000 study.

BACKGROUND: Recently there has been increased interest in the special mental health needs of women. We used data from the PRIME-MD 1000 study to assess gender differences in the frequency of mental disorders in primary care settings, and to explore the potential impact of these differences on health-related quality of life (HRQL). SUBJECTS AND METHODS: One thousand primary care patients (559 women) were interviewed during the PRIME-MD study, which was conducted at four primary care clinics affiliated with university hospitals throughout the eastern United States. Patients completed a one-page questionnaire in the waiting room prior to being seen by the physician; patients and physicians then completed together a clinician evaluation guide that used DSM-III-R algorithms to diagnose mood, anxiety, somatoform, eating, and alcohol related disorders. Health-related quality of life was assessed with the Medical Outcomes Study SF-20 General Health Survey. RESULTS: Women were more likely than men to have at least one mental disorder (43% versus 33%, P < 0.05). Higher rates were particularly prominent for mood disorders (31% of women versus 19% of men, odds ratio [OR] = 1.9, 95% confidence interval [CI] 1.4 to 2.6), anxiety disorders (22% versus 13%, OR = 1.9, CI = 1.3 to 2.8), and somatoform disorders (18% versus 9%, OR = 2.2, CI = 1.5 to 3.4). Psychiatric comorbidity was also more common in women (26% of women had two or more mental disorders versus 15% of men, P < 0.05). Unadjusted HRQL scores, ranging from 0 to 100, with 100 = best health, were all significantly lower in women than in men (eg, physical function = 67 in women versus 76 in men, P < 0.0001; mental health = 69 in women versus 76 in men, P < 0.0001). Many HRQL differences persisted after controlling for age, education, ethnicity, marital status, and number of physical disorders; however, differences in HRQL were eliminated in 5 of 6 domains after controlling for number of mental disorders. When compared with female patients of male physicians, female patients of female physicians demonstrated similar satisfaction with care, health care utilization, HRQL, and recognition rate of mental disorders. CONCLUSIONS: In the 1,000 patients of the PRIME-MD study, mood, anxiety, and somatoform disorders and psychiatric comorbidity were all significantly more common in women than men. The HRQL scores were poorer in women than men, although most of this difference was accounted for by the difference in prevalence of mental disorders. These data suggest that one of the most important aspects of a primary care physician's care of female patients is to screen for and treat common mental disorders.

Health-related quality of life in primary care patients with mental disorders. Results from the PRIME-MD 1000 Study.

OBJECTIVE: To determine if different mental disorders commonly seen in primary care are uniquely associated with distinctive patterns of impairment in the components of health-related quality of life (HRQL) and how this compares with the impairment seen in common medical disorders. DESIGN: Survey. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians using PRIME-MD (Primary Care Evaluation of Mental Disorders) to make diagnoses of mood, anxiety, alcohol, somatoform, and eating disorders. MAIN OUTCOME MEASURES: The six scales of the Short-Form General Health Survey and self-reported disability days, adjusting for demographic variables as well as psychiatric and medical comorbidity. RESULTS: Mood, anxiety, somatoform, and eating disorders were associated with substantial impairment in HRQL. Impairment was also present in patients who only had subthreshold mental disorder diagnoses, such as minor depression and anxiety disorder not otherwise specified. Mental disorders, particularly mood disorders, accounted for considerably more of the impairment on all domains of HRQL than did common medical disorders. Finally, we found marked differences in the pattern of impairment among different groups of mental disorders just as others have reported unique patterns associated with different medical disorders. Whereas mood disorders had a pervasive effect on all domains of HRQL, anxiety, somatoform, and eating disorders affected only selected domains. CONCLUSIONS: Mental disorders commonly seen in primary care are not only associated with more impairment in HRQL than common medical disorders, but also have distinct patterns of impairment. Primary care directed at improving HRQL needs to focus on the recognition and treatment of common mental disorders. Outcomes studies of mental disorders in both primary care and psychiatric settings should include multidimensional measures of HRQL.

Psychiatric comorbidity, health status, and functional impairment associated with alcohol abuse and dependence in primary care patients: findings of the PRIME MD-1000 study.

The psychiatric comorbidity, health, and functioning of primary care patients with alcohol abuse and dependence (AAD) were investigated in a sample of 1,000 patients. Psychiatric symptomatology was assessed with the Primary Care Evaluation of Mental Disorders (PRIME-MD) diagnostic system. Health and functional status was assessed with the Medical Outcomes Study Short Form General Health Survey (SF-20). Results indicated that use of the PRIME-MD system brought about a 71% increase in physician recognition of AAD. AAD patients were diagnosed with substantial psychiatric comorbidity, and they reported poorer health and functioning than did patients without any psychiatric disorders. However, they reported less impairment and psychiatric comorbidity than did patients with other psychiatric disorders. Results also indicated that AAD patients' health and functioning were associated with the presence or absence of psychiatric comorbidity.

Development of the home care client satisfaction instrument.

Client (patient) satisfaction has been studied extensively in the health care sector, yet those receiving home health care services have been the focus of few studies. The purpose of this study was to test the reliability and validity of the Home Care Client Satisfaction Instrument (HCCSI). A total of 400 clients, randomly selected from 20 randomly chosen home care agencies in one state, completed the HCCSI and demographic form. Most respondents were older adults with multiple health problems and their families or informal support systems. Since data were skewed, item analysis was used. The revised instrument (HCCSI-R) is unidimensional and includes 12 items rated on a 5-point Likert scale measuring specific aspects of care. In addition, there are three global measures of satisfaction rated on a 10-point scale. All items except one had significant item-total correlations greater than .59. The total score correlates with likeliness to recommend the agency to others (.37, p = .0001), showing some evidence for criterion-related validity.

Utility of a new procedure for diagnosing mental disorders in primary care. The PRIME-MD 1000 study.

OBJECTIVE: To assess the validity and utility of PRIME-MD (Primary Care Evaluation of Mental Disorders), a new rapid procedure for diagnosing mental disorders by primary care physicians. DESIGN: Survey; criterion standard. SETTING: Four primary care clinics. SUBJECTS: A total of 1000 adult patients (369 selected by convenience and 631 selected by site-specific methods to avoid sampling bias) assessed by 31 primary care physicians. MAIN OUTCOME MEASURES: PRIME-MD diagnoses, independent diagnoses made by mental health professionals, functional status measures (Short-Form General Health Survey), disability days, health care utilization, and treatment/referral decisions. RESULTS: Twenty-six percent of the patients had a PRIME-MD diagnosis that met full criteria for a specific disorder according to the Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition. The average time required of the primary care physician to complete the PRIME-MD evaluation was 8.4 minutes. There was good agreement between PRIME-MD diagnoses and those of independent mental health professionals (for the diagnosis of any PRIME-MD disorder, kappa = 0.71; overall accuracy rate = 88%). Patients with PRIME-MD diagnoses had lower functioning, more disability days, and higher rates of health care utilization than did patients without PRIME-MD diagnoses (for all measures, P < .005). Nearly half (48%) of 287 patients with a PRIME-MD diagnosis who were somewhat or fairly well-known to their physicians had not been recognized to have that diagnosis before the PRIME-MD evaluation. A new treatment or referral was initiated for 62% of the 125 patients with a PRIME-MD diagnosis who were not already being treated. CONCLUSION: PRIME-MD appears to be a useful tool for identifying mental disorders in primary care practice and research.

Physical symptoms in primary care. Predictors of psychiatric disorders and functional impairment.

OBJECTIVE: To examine how the type and number of physical symptoms reported by primary care patients are related to psychiatric disorders and functional impairment. DESIGN: Outpatient mental health survey. SETTING: Four primary care clinics. PATIENTS: One thousand adult clinic patients, of whom 631 were selected randomly or consecutively and 369 by convenience. MAIN OUTCOME MEASURES: Psychiatric disorders as determined by the Primary Care Evaluation of Mental Disorders procedure; the presence or absence of 15 common physical symptoms and whether symptoms were somatoform (ie, lacked an adequate physical explanation); and functional status as determined by the Medical Outcomes Study Short-form General Health Survey. RESULTS: Each of the 15 common symptoms was frequently somatoform (range, 16% to 33%). The presence of any physical symptom increased the likelihood of a diagnosis of a mood or anxiety disorder by at least twofold to three-fold, and somatoform symptoms had a particularly strong association with psychiatric disorders. The likelihood of a psychiatric disorder increased dramatically with increasing numbers of physical symptoms. The prevalence of a mood disorder in patients with 0 to 1, 2 to 3, 4 to 5, 6 to 8, and 9 or more symptoms was 2%, 12%, 23%, 44%, and 60%, respectively, and the prevalence of an anxiety disorder was 1%, 7%, 13%, 30%, and 48%, respectively. Finally, each physical symptom was associated with significant functional impairment; indeed, the number of physical symptoms was a powerful correlate of functional status. CONCLUSIONS: The number of physical symptoms is highly predictive for psychiatric disorders and functional impairment. Multiple or unexplained symptoms may signify a potentially treatable mood or anxiety disorder.

Selected pesticide residues and metabolites in urine from a survey of the U.S. general population.

Residues of toxic chemicals in human tissues and fluids can be important indicators of exposure. Urine collected from a subsample of the second National Health and Nutrition Examination Survey was analyzed for organochlorine, organophosphorus, and chlorophenoxy pesticides or their metabolites. Urine concentration was also measured. The most frequently occurring residue in urine was pentachlorophenol (PCP), found in quantifiable concentrations in 71.6% of the general population with an estimated geometric mean level of 6.3 ng/ml. Percent quantifiable levels of PCP were found to be highest among males. Quantifiable concentrations of 3,5,6-trichloro-2-pyridinol (5.8%), 2,4,5-trichlorophenol (3.4%), para-nitrophenol (2.4%), dicamba (1.4%), malathion dicarboxylic acid (0.5%), malathion alpha-monocarboxylic acid (1.1%), and 2,4-D (0.3%) were found, but at much lower frequencies. No quantifiable levels of 2,4,5-T or silvex were found. Preliminary analyses showed an apparent relationship between residue concentration and two measures of urine concentration (osmolality and creatinine). A large segment of the general population of the United States experienced exposure to certain pesticides, including some considered biodegradable, during the years 1976-1980.

Psychological side effects of breast cancer screening.

Evaluated the impact of receiving abnormal mammogram results on women's anxiety and breast cancer worries and on their breast self-examination (BSE) frequency and intentions to obtain subsequent mammograms. A telephone survey was conducted with 308 women 50 years old and older approximately 3 months following a screening mammogram. Subjects included women with suspicious abnormal mammograms, nonsuspicious abnormal mammograms, and normal mammograms. Women with suspicious abnormal mammograms exhibited significantly elevated levels of mammography-related anxiety and breast cancer worries that interfered with their moods and functioning, despite the fact that diagnostic work-ups had ruled out breast cancer. Women with moderate levels of impairment in mood or functioning were more likely to practice monthly BSE than women with either high or low levels of impairment. Breast cancer worries, perceived susceptibility to breast cancer, and physician encouragement to get mammograms all exhibited independent positive relationships to mammogram intentions.

Olfactory identification deficits in HIV infection.

OBJECTIVE: Impaired odor identification is described in a number of CNS disorders, and human immunodeficiency virus (HIV) infects the CNS in a large percentage of patients. To evaluate whether impaired olfaction may indicate CNS disease, the authors measured odor identification in patient groups defined along a continuum of progressive immunodeficiency and in a comparison group. METHOD: Most of the 42 HIV-infected patients in the study were outpatients in a clinic specializing in treatment of HIV-infected individuals. The comparison subjects were 37 healthy age- and sex-matched individuals who were recruited from hospital and medical school personnel. Ten of the patients were HIV-seropositive but had no symptoms, 24 had clinical evidence of immunocompromise, and eight had HIV dementia. All subjects were given the University of Pennsylvania Smell Identification Test, which presents common odorants and requires the subject to identify the odor from a four-item word list. The data were analyzed by using analysis of variance after arc-sine transformation and Scheffé post hoc analysis. RESULTS: All patients scored significantly lower on the Smell Identification Test than did the comparison subjects. The patients with HIV dementia had significantly lower scores than did the other two groups of patients. CONCLUSIONS: Clinically, impaired olfaction might serve as a marker of early CNS HIV involvement. Future studies should attempt to match comparison and experimental populations for socioeconomic status and HIV risk behavior.
