Treatment persistence: a comparison among patients with schizophrenia who were initiated on atypical antipsychotic agents.

BACKGROUND: Although clinical trials have demonstrated the efficacy of atypical antipsychotic agents in reducing symptoms of schizophrenia, the likelihood of sustaining control of schizophrenic symptoms may depend on treatment persistence. OBJECTIVE: In this study, we compared treatment persistence between patients who were initiated on risperidone or olanzapine, the two most widely prescribed atypical antipsychotic agents. METHOD: We identified patients with schizophrenia by ICD-9-CM codes (> or =1 inpatient or > or =2 outpatient ICD-9-CM codes > or =7 days apart) between 1 July 1998 and 30 June 1999. We further selected those who were prescribed the target drug during 1 April 1999 through 31 March 2000 provided that they were not on any antipsychotic agents during the prior 6 months. Using event history analysis, we compared the treatment persistence in terms of hazard ratio between olanzapine and risperidone initiators, adjusting for patient's sociodemographic and clinical characteristics. RESULTS: Following the initiation of the target drug, more patients switched from risperidone to olanzapine than vice versa. However, among patients with schizophrenia who had comorbid diabetes, there were more patients who made a switch from olanzapine to risperidone; whereas among those who used anxiolytics, there were more patients who switched from risperidone to olanzapine. Finally, olanzapine initiators had decreased hazards of discontinuation by 14% (unadjusted; P < 0.001) and 12% (adjusted; P = 0.002), respectively, than risperidone initiators. CONCLUSIONS: Compared with risperidone, olanzapine seems to be better tolerated by patients as indicated by better treatment persistence. As such, initiation of olanzapine may increase the likelihood of sustaining control of symptoms of schizophrenia. Future research needs to provide a more comprehensive assessment of treatment persistence by considering other antipsychotic agents in the study and developing models to assess treatment persistence and switching as two interdependent competing risks.

Adjunctive use of atypical antipsychotics and anticholinergic drugs among patients with schizophrenia.

BACKGROUND: Treatment of schizophrenia with antipsychotics is often associated with extrapyramidal symptoms (EPS), a disorder involving involuntary muscle movement. Because EPS are often associated with the use of antipsychotics, anticholinergic agents are often indicated. OBJECTIVE: In this observational, retrospective study, we examined whether the initiation of olanzapine or risperidone, the two most widely prescribed atypical antipsychotics, is related to the adjunctive use of anticholinergic agents. METHOD: We identified patients with schizophrenia from outpatient clinics in the Veterans Health Administration (VA) and defined initiation of olanzapine or risperidone as patients who were not on any antipsychotics for 6 months and subsequently initiated on the target drug between 1/4/1999 and 31/3/2000. The data were analysed using tests of means or chi-square tests. RESULTS: The study yielded two major findings. First, compared with risperidone initiators, there were significantly fewer olanzapine initiators who used at least one anticholinergic agent adjunctively. Secondly, among olanzapine or risperidone initiators, patients who used at least one anticholinergic agent adjunctively tended to stay on the target drug significantly longer than those who did not use any anticholinergic agent adjunctively with the target drug. CONCLUSION: As the use of anticholinergics is a proxy for the presence of EPS, these findings suggest that risperidone may be more associated with EPS than olanzapine. However, to assess the benefits and side effects associated with olanzapine or risperidone, future research needs to examine various patient outcomes resulting from the initiation of each drug.

Initiation of atypical antipsychotic agents and health outcomes in patients with schizophrenia.

BACKGROUND: Although pharmacological treatments are available for patients with schizophrenia, there is a lack of systematic and comprehensive evaluation of health outcomes following the initiation of atypical antipsychotic agents. OBJECTIVE: To assess the effects of the initiation of olanzapine or risperidone, the two most widely prescribed atypical antipsychotics, on patients' health outcomes, as measured by changes in patient clinical characteristics between 6 months prior to and post-initiation. METHOD: We identified patients with schizophrenia by >1 inpatient or > or = 2 outpatient ICD-9-CM codes (> or = 7 days apart) between 1 July 1998 and 30 June 1999, and those who were initiated on olanzepine or risperidone during the period 1 April 1999 to 31 March 2000 inclusive. We then subdivided these patients into three groups: (i) those who were not on olanzapine or risperidone, (ii) those who were not on any atypical agents, and (iii) those who were not on any antipsychotic agents, for 6 months prior to being issued with the new prescription. Using test of means or chi-square tests, we examined whether the initiation of olanzapine or risperidone is related to different changes in patient clinical indicators, such as number of drugs for psychiatric conditions, use of psychiatric services, and use of non-psychiatric services. RESULTS: Between pre- and post-initiation, olanzapine initiators had a greater decrease in the number of psychiatric hospitalizations and use of psychotropic agents, whereas risperidone initiators had a greater reduction in the number of non-psychiatric hospitalizations. The initiation of olanzapine and risperidone appear to be associated with different patient health outcomes. Compared with olanzapine initiators, risperidone initiators had a greater increase in the use of treatments related to mental health, but had greater decrease in the use of treatments related to physical health. CONCLUSION: Despite olanzapine and risperidone being often perceived as similar antipsychotic agents, our results suggest that the clinical outcomes associated with their use are different. Outcome data from routine clinical practice are required to provide a more comprehensive assessment of these drugs.

Patient characteristics and prescription patterns of atypical antipsychotics among patients with schizophrenia.

BACKGROUND: Schizophrenia, one of the leading causes of disability, contributes substantially to the use of medical and mental health services. The treatment of schizophrenia is therefore particularly important to reduce deficits across a large number of neurocognitive domains. OBJECTIVE: To describe the prescription (e.g. initiation and switching) patterns of atypical antipsychotic agents and examine the extent to which patient sociodemographic and clinical characteristics are associated with the prescription patterns of atypical antipsychotics among patients with schizophrenia. METHODS: Using unique data sources from the Veterans Health Administration (VA), the study identified 89 107 patients with schizophrenia based on at least one inpatient or more than or equal to two outpatients' ICD-9-CM codes (> or =7 days apart). We defined a prior 6-month (1/1/99 to 6/30/99) and a post 6-month (7/1/99 to 12/31/99) period to describe patterns of initiation and switching of atypical antipsychotics. RESULTS: Only a small number of patients were on clozapine (1.8%) and quetiapine (1.4%). More patients were prescribed olanzapine (23%) than risperidone (20%) (P < 0.001). Compared with patients who were on risperidone, those who were on olanzapine were younger (P < 0.001), more likely Hispanic (P < 0.001), more likely married (P < 0.05), had more service-connected disability (P < 0.001), had fewer numbers of physical comorbidities (P < 0.001), and a lower body mass index (BMI) (P < 0.05). CONCLUSION: Olanzapine and risperidone appear to be prescribed to patients with different sociodemographic and clinical characteristics. Future research needs to explore the reasons for those differences.

Pulsatile ocular blood flow in asymmetric exudative age related macular degeneration.

BACKGROUND/AIMS: Decreased perfusion or increased vascular resistance of the choroidal vessels had been proposed as the vascular pathogenesis for age related macular degeneration (AMD). This study planned to answer the question whether pulsatile ocular blood flow (POBF) was different in patients with asymmetric exudative AMD between eyes with drusen, choroidal neovascularisation (CNV), or disciform scar. METHODS: 37 patients with asymmetric exudative AMD were enrolled in this observational case series study. POBF were measured in both eyes of each subject. Eyes with high myopia, anisometropia, recent laser treatment, and glaucoma were excluded. RESULTS: After adjusting for ocular perfusion pressure, intraocular pressure, and pulse rate, multivariate regression analysis with generalised estimating equation showed POBF was significantly higher in eyes with CNV (1217 (SD 476) microl/min) than the contralateral eyes with drusen (1028 (385) microl/min) (p = 0.024). Eyes with disciform scar had lower POBF than the contralateral eyes with drusen (999 (262) microl/min and 1278 (341) microl/min, respectively, p<0.001). There was no significant correlation between the POBF and the lesion size of the CNV. CONCLUSION: The POBF in eyes with drusen was lower than their fellow eyes with CNV, but higher than their fellow eyes with disciform scar. This finding suggests that haemodynamic differences between fellow eyes in individuals are relevant to the development of CNV and the formation of disciform scar. Further studies on the follow up patients might shed light on the pathogenesis of exudative AMD.

Ovarian hormones in man: their effects on resting vascular tone, angiotensin converting enzyme activity and angiotensin II-induced vasoconstriction.

AIMS: Oestrogens in women have been shown to cause vasodilation which may reflect alterations in the activity of vascular angiotensin converting enzyme (ACE) and/or sensitivity to angiotensin II. The aim of this study was to assess the effect of ovarian hormones on vascular tone, vascular ACE activity and vasoconstriction to angiotensin II in males. METHODS: Eight volunteers were randomised in a crossover design to oestradiol, medroxy-progesterone, and placebo. Vasoconstriction to angiotensin I and angiotensin II was assessed by forearm plethysmography. RESULTS: Although baseline forearm flow was increased with oestradiol, suggesting generalized vasodilation, there were no changes in the vasoconstrictor responses to angiotensin I or angiotensin II. Medroxy-progesterone affected neither baseline flow nor vasoconstrictor responses. The results expressed as percentage reduction in flow (mean +/- s.d.) were: angiotensin I 48 pmol ml-1: placebo -48 +/- 14%; oestradiol -42 +/- 16%; medroxyprogesterone -43 +/- 8% and for angiotensin II 16 pmol ml-1: placebo -42 +/- 10%; oestradiol -39 +/- 11%; medroxyprogesterone -46 +/- 13%. CONCLUSIONS: Acute administration of oestradiol caused vasodilation in males, the effect was not due to alterations in vascular ACE activity or to altered sensitivity to angiotensin II.

Decision-making preference and opportunity in VA ambulatory care patients: association with patient satisfaction.

Using data from the Veterans Health Study, associations were examined for decision-making preference, decision-making opportunity, and satisfaction with medical care among a sample of 266 men who use Department of Veterans Affairs (VA) ambulatory health care services. Results indicated that veterans with a high preference for involvement in decision-making and low provider-offered decision-making opportunities had significantly lower satisfaction with medical care compared to veterans with either low preference for decision-making involvement with high or low opportunity, or those with a high decision-making preference and high decision-making opportunity. The findings suggest that health care providers may increase patient satisfaction with medical care by providing opportunities for decision-making to patients who prefer involvement in their health care decision-making. Provider strategies for increasing patient decision-making involvement are discussed.

Neurohormonal reactivation in heart failure patients on chronic ACE inhibitor therapy: a longitudinal study.

BACKGROUND: Angiotensin Converting Enzyme inhibitors reduce mortality in heart failure. One therapeutic mechanism is believed to be the reduction of circulating angiotensin II and aldosterone. However, the Renin-Angiotensin-Aldosterone axis (RAAS) is not uniformly suppressed during therapy for heart failure. This effect has been referred to as 'angiotensin II reactivation' and 'aldosterone escape' and their reactivation may herald clinical deterioration. In the CONSENSUS I trial, correlations were seen between mortality, and angiotensin II and aldosterone. Furthermore, mortality was lower in those with good angiotensin II suppression. Therefore, neurohormonal elevation despite adequate treatment may associate with a poorer prognosis. AIMS: To follow chronic heart failure patients on ACE inhibitors for 18 months to assess whether or not angiotensin II and aldosterone reactivation are progressive with time, whether reactivation of both occurs simultaneously, and whether different ACE inhibitors have different neurohormonal profiles. METHODS AND RESULTS: We studied 22 patients (M/F 19:3, 72.5+/-7 years) on stable ACE inhibitors. Five times, in 18 months, samples were taken for neurohormones and ACE activity. Mean levels of neurohormones were remarkably stable over time, although captopril takers had generally higher angiotensin II, but lower aldosterone and renin. Aldosterone 'escape' (> 80 pg/ml) occurred in 13/97 samples (13.5%), in 5/22 (23%) individuals. Angiotensin II was elevated > or =10 pg/ml in 8/102 samples (8%), in 6/22 (27%) individuals. Four subjects had isolated angiotensin II reactivation, and three had aldosterone escape alone. On regression analyses between neurohormones in captopril takers there were significant correlations between; renin and angiotensin II (r = 0.62; P<0.02); angiotensin II and aldosterone (r = 0.6; P<0.02); and renin and aldosterone (r = 0.92; P<0.00001). CONCLUSION: In stable heart failure patients un-suppressed levels of angiotensin II and aldosterone occur despite therapy, but they are not necessarily progressive, nor simultaneous. Furthermore, contemporaneous serum ACE activity makes it unlikely the data presented reflects poor compliance. The results suggest that captopril takers may have different neurohormonal profiles, i.e. higher angiotensin II, and also better correlations between RAAS components, compared to longer acting preparations, although the numbers are small. Our data supports that of Swedberg et al. who showed reductions in both aldosterone and angiotensin II due to ACE inhibitor therapy, but no correlation between ACE activity and angiotensin II and only a limited correlation (r = 0.37) between angiotensin II and aldosterone. This suggests that the interaction between the components of the renin-angiotensin system is not simple and linear. The fact that each phenomenon appears to occur in isolation means that neurohormonal monitoring of individual could provide useful information to direct additional therapy. The RALES study has demonstrated reduced mortality from the addition of spironolactone to an ACE inhibitor emphasising the benefit of enhanced suppression of aldosterone in heart failure. Captopril may be less effective at suppressing the RAAS due to its short duration of action which would logically be associated with a more fluctuating pattern of ACE inhibition. In the presence of high levels of renin and angiotensin I even small differences in ACE activity will produce large variations in angiotensin II levels. Further studies should be directed at understanding the different mechanisms behind angiotensin II and aldosterone generation during ACE inhibition.

The effect of nitric oxide inhibition on the renin response to frusemide, in man.

AIMS: We wished to see if renin release in man was inhibited by nitric oxide blockade, suggesting a role for nitric oxide in renin release. Evidence from animal studies has shown variable effects on renin release depending on the model and stimulus used. METHODS: Ten normal male volunteers, received either L-NMMA as a front loaded infusion (4 mg kg-1 bolus, with 4 mg kg-1 infusion), or placebo, followed by an intravenous bolus of 5 mg frusemide to stimulate renin. To investigate whether any alteration in renin release was due to the pressor effect of the L-NMMA, the experiment was repeated using an equipressor dose of phenylephrine (0.5 microg kg-1 min-1 ). RESULTS: L-NMMA caused the expected increase in mean arterial pressure (96+/-2.6 vs 89+/-3.3 mmHg P<0.05 [mean+/-s.e.mean]), and a reduction in heart rate (59+/-3.6 vs 67+/-2.5 beats min-1 P<0.05). L-NMMA completely blocked the renin rise following the bolus of frusemide (1.18+/-0.196 vs 1.96+/-0.333 ng ml-1 h-1 P<0.01). Phenylephrine 0.5 microg kg-1 min-1 produced very similar haemodynamic effects to L-NMMA, and also suppressed the renin response to frusemide (1.43+/-0.290 vs 2.67+/-0.342 ng ml-1 h-1 P<0. 01). CONCLUSIONS: In man, the renin inhibition seen with NO synthesis inhibition is similar to that seen with a standard pressor stimulus, hence inhibition of renin in man by L-NMMA, may be due to both direct effects on macula densa cells and indirect haemodynamic effects.

How often are angiotensin II and aldosterone concentrations raised during chronic ACE inhibitor treatment in cardiac failure?

OBJECTIVE: Angiotensin II (AII) and aldosterone are not always fully suppressed during chronic angiotensin converting enzyme (ACE) inhibitor treatment. In congestive heart failure (CHF) such failure of hormonal suppression is associated with increased mortality. This study examined how common AII and aldosterone increases are observed during routine clinical practice. PATIENTS AND METHODS: 91 patients with symptomatic (mean New York Heart Association class 2.7) CHF (mean (SD) left ventricular ejection fraction 29.9 (8)%, range 9-46%) were studied 4-6 hours after ACE inhibitor dosing. A representative range of ACE inhibitors (enalapril, lisinopril, captopril, perindopril, and fosinopril) was examined. RESULTS: Supine measurements showed a wide range of AII (10.5 (25.5) pg/ml), aldosterone (130.8 (136) pg/ml), and serum ACE (12.1 (13.3) EU/l; excludes captopril data) concentrations on diuretics. AII concentrations > 10 pg/ml were seen in 15% of patients, and aldosterone concentrations > 144 pg/ml were seen in 38% of patients. AII concentrations were significantly correlated (p < 0.001) with ACE but not with aldosterone concentrations. Aldosterone concentrations were not significantly correlated with ACE concentrations. CONCLUSIONS: AII "reactivation" occurred in 15% and failure of aldosterone suppression in 38% of routine CHF patients taking ACE inhibitor treatment. AII "reactivation" was associated with both low and high levels of ACE activity, which suggests that multiple different mechanisms are at play. In patients with high plasma ACE concentrations, non-compliance should be considered along with inadequate dose titration. In patients with low plasma ACE and high AII concentrations, non-ACE mediated production of AII may be operative. Raised aldosterone concentrations appear to be more common than AII "reactivation". It is important to establish the cause of detectable or increased AII concentrations in a heart failure patient treated with an ACE inhibitor. The measurement of serum ACE may help to identify the likely cause as poor compliance or inadequate dose.

Lisinopril improves arterial function in hyperlipidaemia.

Endothelial function is defective in hypercholesterolaemia, and animal models have suggested that angiotensin-converting enzyme inhibitors may prevent arterial damage. We studied the effect of 6 months treatment with lisinopril on endothelial function in a group of patients with hypercholesterolaemia. Forty patients were studied. Forearm blood flow responses to acetylcholine and sodium nitroprusside were assessed by venous occlusion plethysmography. Subjects were then randomized in a double-blind fashion to receive either lisinopril, 20 mg/day (n=20), or placebo (n=20) for 6 months. Plethysmography was then repeated. Baseline variables between groups were comparable. In the lisinopril group blood pressure fell significantly [systolic: 145+/-4 to 128+/-4 mmHg (P<0.001); diastolic: 84+/-2 to 74+/-2 mmHg (P<0.001)]. An improvement was found in the vasodilatory response (expressed as a ratio of the infused/control arm) to acetylcholine, e.g. 3.33+/-0.3 (pre) versus 4.45+/-0.48 (post) at 30 microg/ml (P<0.03), and also to nitroprusside, e.g. 3.0+/-0.2 (pre) versus 3.86+/-0.3 (post) at 3.2 microg/ml (P<0.01). In the placebo group vasodilatation did not change significantly in response to acetylcholine, and nitroprusside responses were unchanged. The data presented suggest that 6 months of lisinopril therapy have a beneficial effect on arterial function in subjects with hyperlipidaemia. Further work should now investigate whether angiotensin-converting enzyme inhibitors are beneficial in reducing mortality and morbidity in hypercholesterolaemia.

Indocyanine green angiography of central serous chorioretinopathy.

BACKGROUND: Fluorescein angiography has not been particularly useful in studying the choroidal vasculature because of limited fluorescence transmission through the retinal pigment epithelium (RPE). Indocyanine green (ICG), a dye that absorbs and fluoresces in the near-infrared range and does not leak extensively through the choriocapillaries, because of its highly protein-bound nature, allows improved imaging of the choroid compared with fluorescein angiography. This study was performed to evaluate changes in the choroidal circulation in the eyes of patients with central serous chorioretinopathy (CSCR) using ICG angiography. METHODS: We prospectively performed ICG angiography and fluorescein angiography in 41 eyes with classic or chronic CSCR (diffuse retinal pigment epitheliopathy) to investigate the choroidal abnormalities. RESULTS: The ICG angiographic studies revealed choroidal staining in all eyes of the two forms of CSCR. Classic CSCR (35 eyes), when compared with the chronic form (6 eyes), were associated with more RPE leakage (89% vs 33%; p = 0.008), more prominent ischemic lobules (69% vs 0; p = 0.003), and less late phase hypofluorescent spots (46% vs 100%; p = 0.02). CONCLUSIONS: Choroidal hyperpermeability may be a causative factor of acute or chronic CSCR and may help in the diagnosis of atypical cases of CSCR. The differences in the results between these two types of CSCR using ICG angiography, allowed for a better understanding of the choroidal hemodynamic change than fluorescein angiography.

Nitric oxide: an important role in the maintenance of systemic and pulmonary vascular tone in man.

AIMS: The aim of this study was to examine whether nitric oxide (NO) has an important role in maintaining basal vascular tone in normal man by examining the effects of nitric oxide inhibition using N(G)-monomethyl-L-arginine (L-NMMA) on systemic and pulmonary haemodynamics. METHODS: Ten normal male volunteers 26 +/- 1.6 years were studied on two separate occasions in a double-blind, placebo controlled crossover study. They were randomised to receive either a continuous infusion of L-NMMA (4 mg kg(-1) h(-1)) with a front loaded bolus (4 mg kg(-1)) or volume matched placebo. Pulsed wave Doppler echocardiography was used to measure cardiac output (CO), mean pulmonary artery pressure (MPAP) and hence systemic vascular resistance (SVR) and total pulmonary vascular resistance (TPR). Measurements were made prior to infusion (t0) and after 4, 8, and 12 min (t1, t2 and t3). RESULTS: Infusion of L-NMMA significantly increased mean arterial blood pressure (MAP), SVR and TPR and significantly reduced heart rate (HR), stroke volume (SV) and CO compared to placebo. These effects were observed at t1 and persisted during the entire infusion period. CONCLUSIONS: These results are consistent with a role for basal nitric oxide generation in the maintenance of basal systemic and pulmonary vascular tone in normal man.

Glaucoma following congenital cataract surgery.

BACKGROUND: Glaucoma is a well known complication that arises after congenital cataract surgery. The purpose of this research was to study eyes that manifested glaucoma after congenital cataract surgery and to identify associated factors. METHODS: A retrospective review of patients who received cataract surgery before the age of five was conducted. The chi-squared test for association was used to evaluate risk factors. RESULTS: One hundred and forty eyes of 85 patients were studied. Nineteen eyes of 12 patients had glaucoma, among which 79% was open angle. Patients who underwent secondary membranectomy for visual axis occlusion had a higher risk of glaucoma, especially when secondary membranectomy was performed within one year of primary surgery. Of eight eyes with microcornea, none developed glaucoma after surgery. No significant difference in outcome was found among the surgical methods of cataract removal. CONCLUSIONS: Aggressive clearance of lens cortex during surgery is important. Secondary membranectomy for clearing the visual axis occlusion is associated with post operative glaucoma. Frequent and long-term patient follow-up is mandatory since glaucoma may manifest many years after congenital cataract surgery.

Choroidal involvement in Wegener's granulomatosis: a case report.

Wegener's granulomatosis is a necrotizing, granulomatous vasculitis. It usually causes sinusitis, pneumonitis and glomerulonephritis. The common ocular manifestations include conjunctivitis, scleritis, peripheral keratitis and orbital inflammation. We report the case of a 50-year-old woman with Wegener's granulomatosis and very severe ocular complications who underwent bilateral enucleation. The pathologic findings of the eyeballs revealed granulomatous necrotizing scleritis, perivasculitis and granulomatous choroiditis. The last, as far as we know, has not yet been reported.

Recidivism rates among child molesters and rapists: a methodological analysis.

We address the high variability in sex offender recidivism rates by examining several of the critical methodological differences that underlie this variability. We used a dataset on 251 sex offenders (136 rapists and 115 child molesters) who were discharged over a 25-year period to examine changes in recidivism as a function of changes in dispositional definition of reoffense (e.g., arrest or conviction), changes in the domain of criminal offenses that are considered, and changes in the length of exposure time. The data indicate that: (a) both rapists and child molesters remain at risk to reoffend long after their discharge, in some cases 15-20 years after discharge; (b) there was a marked underestimation of recidivism when calculating a simple proportion (%) consisting of those who were known to have reoffended during the follow-up period, and (c) there was a marked underestimation of recidivism when the criterion was based on conviction or imprisonment. Forensic, clinical and policy implications of this high variability are discussed.

Risk factors associated with recidivism among extrafamilial child molesters.

This study examined the predictive efficacy of 10 rationally derived, archivally coded variables for assessing reoffense risk among extrafamilial child molesters. Follow-up data on 111 child molesters who were discharged from the Massachusetts Treatment Center between 1960 and 1984 were used. Degree of sexual preoccupation with children, paraphilias, and number of prior sexual offenses predicted sexual recidivism. Juvenile and adult antisocial behavior, paraphilias, and low amount of contact with children predicted nonsexual victim-involved and violent recidivism. Area under the receiver-operating characteristic curves in all three analyses indicated discrimination that was substantially better than chance, ranging from .73 to .79.
