Health Service Utilization Patterns Among Adults With Congenital Heart Disease: A Population-Based Study.

Background Several studies have examined hospitalizations among patients with adult congenital heart disease (ACHD). Few investigated other services or utilization patterns. Our aim was to study service utilization patterns and predictors among patients with ACHD. Methods and Results We identified 11 653 patients with ACHD aged ≥18 years (median, 47 years), through electronic records of 2 large Israeli healthcare providers (2007-2011). The association between patient, disease, and sociogeographic characteristics and healthcare resource utilization were modeled as recurrent events accounting for the competing death risk. Patients with ACHD had high healthcare utilization rates compared with the general population. The highest standardized service utilization ratios (SSRs) were found among patients with complex congenital heart disease including primary care visits (SSR, 1.53; 95% CI, 1.47-1.58), cardiology outpatient visits (SSR, 5.17; 95% CI, 4.69-5.64), hospitalizations (SSR, 6.68; 95% CI, 5.82-7.54), and days in hospital (SSR, 15.37; 95% CI, 14.61-16.12). Adjusted resource utilization hazard increased with increasing lesion complexity. Hazard ratios (HRs) for complex versus simple disease were: primary care (HR, 1.14; 95% CI, 1.06-1.23); cardiology outpatient visits (HR, 1.40; 95% CI, 1.24-1.59); emergency department visits (HR, 1.19; 95% CI, 1.02-1.39); and hospitalizations (HR, 1.75; 95% CI, 1.49-2.05). Effects attenuated with age for cardiology outpatient visits and hospitalizations and increased for emergency department visits. Female sex, geographic periphery, and ethnic minority were associated with more primary care visits, and female sex (HR versus men, 0.89 [95% CI, 0.84-0.94]) and periphery (HR, 0.72 [95% CI, 0.58-0.90] for very peripheral versus very central) were associated with fewer cardiology visits. Arab minority patients also had high hospitalization rates compared with the majority group of Jewish or other patients. Conclusions Healthcare utilization rates were high among patients with ACHD. Female sex, geographic periphery, and ethnicity were associated with less optimal service utilization patterns. Further research should examine strategies to optimize service utilization in these groups.

Depression and anxiety are associated with high health care utilization and mortality among adults with congenital heart disease.

BACKGROUND: The significance of depression/anxiety among ACHD patients in terms of health care utilization is unknown and data on the association with mortality are scarce. METHODS: Analyses comprised 8334 ACHD patients, age ≥ 18 years, insured by a large healthcare organization (2007-2011). Depression/anxiety were determined by diagnoses and treatments recorded in the organization database. Adjusted utilization relative rates (RRs) were estimated with negative binomial models and mortality hazard ratios (HRs) with the Cox proportional hazard model. RESULTS: ACHD patients with depression/anxiety (N = 2950, 35%) were more likely to be older (mean ±â€¯SD: 54 ±â€¯17 vs. 45 ±â€¯18 years), women (61% vs. 45%), and have comorbidities than counterparts without depression/anxiety. Following multivariable adjustment, patients with depression/anxiety had more primary care and cardiology clinic visits, more emergency department visits and more hospitalizations. RRs (95% confidence interval) were: 1.31 (1.27-1.35); 1.07 (1.01-1.13); 1.60 (1.46-1.77); and 1.18 (1.08-1.29) respectively, for diagnosis before the study period, and 1.36 (1.31-1.42); 1.22 (1.14-1.30); 1.43 (1.24-1.60) and 1.47 (1.33-1.64), respectively, for diagnosis during the study. Stratifying by age, the highest adjusted primary care and cardiology visit RRs were found among 18-24 years old patients and the lowest among patients ≥65 years. Between 2007 and 2017, 905 patients died. Depression/anxiety were associated with increased mortality risk with adjusted HRs: 1.10 (95% CI: 0.94-1.29) for past diagnosis and 1.40 (1.17-1.67) for study period depression/anxiety diagnosis. CONCLUSIONS: Depression/anxiety in ACHD patients is associated with increased health-care utilization and a higher risk of death. The efficacy of addressing patients' psychosocial needs in optimizing health-care utilization and improving prognosis needs further evaluation.

Time to diagnosis of fibromyalgia and factors associated with delayed diagnosis in primary care.

Fibromyalgia is a complex disorder, and its diagnosis often comprises a challenge for physicians. We aimed to assess the time from the appearance of early symptoms to the definite diagnosis of fibromyalgia and to delineate patient and physician factors associated with this delay. The database of a large healthcare services provider was searched for all fibromyalgia patients (age 21 years or more) diagnosed during 2008-2011. Patients with a diagnosis confirmed by a physician with a relevant specialization were compared with age- and sex-matched nonfibromyalgia controls to retrospectively identify an initial complaint pattern characteristic of fibromyalgia. The time from initial complaints to fibromyalgia diagnosis, as well as the fraction of time while the patient was treated continuously by the same primary physician as at time of diagnosis, was assessed among all eligible fibromyalgia patients. An initial complaint pattern was identified in 67.9% of 2,055 patients with confirmed fibromyalgia vs. 27.6% of 9,172 controls. Among 2,369 (69.0%) of all 3,434 eligible patients with fibromyalgia, mean (SD) total time to diagnosis was 6.42 (3.57) years and mean (SD) time while treated by the same primary physician as at diagnosis was 3.75 (3.26) years. Comorbidity, younger patient, and older physician age were associated with longer time to diagnosis. By analysis of "real-world" data, fibromyalgia remains a complex and elusive diagnosis, taking years to be properly diagnosed. There is a need to increase the awareness of this syndrome among physicians, especially of older age.

Characterization of adherence and persistence profile in a real-life population of patients treated with adalimumab.

AIMS: Published data on long-term adherence and persistence with adalimumab (Humira® ) in clinical practice are scarce and often limited to selected patient populations. This study assessed adherence with adalimumab across different indications and identified correlates and outcomes of poor adherence. METHODS: We analysed data originating from the electronic database of Maccabi Healthcare Services (MHS) that includes 2.1 million enrolees. We randomly selected patients with at least one dispense of adalimumab since it was included in the local health basket in Israel in 2008 until the end of 2013. Patients with the following indications (n = 1339) were included: Crohn's disease (CD), ulcerative colitis (UC), rheumatoid arthritis (RA), psoriatic arthritis (PSA), ankylosing spondylitis (AS) and psoriasis. Adherence with therapy was assessed by the medication possession ratio (MPR) during the follow-up period. RESULTS: Good adherence (MPR ≥ 80%) was observed among 80% of study patients and was associated with lower risk for ≥1 hospitalization per year of follow-up (adjusted-OR = 1.94, 95% CI:1.15-3.28). Patients with AS and CD persisted on adalimumab therapy the most, reaching median use of 27.0 and 26.7 months, respectively. Half (52.4%) of the patients discontinued treatment during a mean (SD) follow-up of 3.07 (1.71) years. High socioeconomic status was associated with lower risk for discontinuation (adjusted-HR = 0.74; 0.60-0.91). UC and concomitant prednisolone use were associated with increased risk for treatment discontinuation (HR = 1.31; 1.00-1.72, and HR = 1.40; 1.17-1.68, respectively). CONCLUSION: Our results indicate encouraging persistence and adherence with adalimumab of patients with inflammatory conditions.

Adherence and Persistence with Drug Therapy among Fibromyalgia Patients: Data from a Large Health Maintenance Organization.

OBJECTIVE: To assess 1-year persistence and adherence rates with drug therapy among patients with fibromyalgia (FM) and to identify factors associated with therapy discontinuation. METHODS: This retrospective, cohort study included members ≥ 21 years old from the Maccabi Healthcare Services, a large health maintenance organization in Israel, who were diagnosed with FM from 2008 through 2011. Medications of interest included the anticonvulsant pregabalin, antidepressants [selective serotonin reuptake inhibitor (SSRI), serotonin/norepinephrine reuptake inhibitor (SNRI)], and tricyclic antidepressants (TCA). Time to treatment discontinuation and proportion of days covered (PDC) with FM-specific therapies during the year from first dispensed were analyzed. PDC < 20% was considered low adherence and PDC ≥ 80% was considered high adherence. Logistic regression models were constructed for multivariable analyses. RESULTS: Overall, 3932 patients with FM were included; 88.7% were female. Pre-diagnosis use of medication of interest was documented in 41% of the study population. Of the remaining 2312 patients, 56.1% were issued a prescription, 45.0% were dispensed at least 1 medication in the year following diagnosis, and only 28.8% had prescriptions filled twice within the first year from diagnosis. Among newly prescribed patients, 1-year discontinuation was highest for TCA (91.0%) and lowest for SSRI/SNRI antidepressants (73.7%). Over half of the patients (60.5%) had fewer than 20% of the days covered by any medication during the year and only 9.3% were very adherent (PDC ≥ 80%). CONCLUSION: This study clearly shows that in an Israeli "real-life" population of patients with FM, persistence and adherence with FM therapy in the year following diagnosis is remarkably low.

Comprehensive healthcare resource use among newly diagnosed congestive heart failure.

BACKGROUND: Congestive heart failure (CHF) is among the most common causes of hospital admissions and readmissions in the Western world. However, the burden of ambulatory care has not been as well investigated. The objective of this study was to assess the relative burden and direct medical costs of CHF including inpatient and outpatient care. METHODS: We used longitudinal clinical data from a two-million member health organization in Israel (Maccabi Healthcare Services) to identify adults with newly diagnosed CHF between January 2006 and December 2012, either in the in- or outpatient setting. Adults without CHF were age- and sex-matched to CHF patients and healthcare utilization and all modes of healthcare costs were compared among them, excluding those in their last year of life. RESULTS: The burden posed by 6592 CHF patients was significantly (p < 0.001) larger than that of 32,960 matched controls. CHF patients had significantly higher rates of baseline comorbidity and healthcare utilization compared to non-CHF controls. This was evident in all categories of healthcare services and expenses, including in- and outpatient visits, laboratory expenses, medication costs, among younger and older, men and women. Among those who incurred any healthcare costs, younger (45-64y) and older (65 + y) subjects with CHF were observed to have about 3.25 (95% CI: 2.96-3.56) and 2.08 (95% CI: 1.99-2.17) times the healthcare costs, respectively, compared to subjects without CHF after adjusting for patient characteristics. CONCLUSION: CHF is associated with an overall two- to three-fold higher cost of healthcare services depending on patient age, accounting for over half of all healthcare costs incurred by elderly CHF patients, and more than two-thirds of all costs among younger CHF patients. Observations of the large burden posed on one of the youngest societies in the developed world are profound, implicative of great opportunities to control the costs of CHF. Further research to understand how resource use impacts health outcomes and quality of care is warranted.

No male predominance in offspring of women with rheumatoid arthritis or systemic lupus erythematosus.

To assess the proportion of male versus female offspring of women diagnosed with SLE or RA, disorders in which female predominance is well known and PsA a disease in which female dominance is less established. The study population encompassed all females aged 16-46, who were members of the Maccabi Health Services (MHS) throughout the period of 2000-2011 and had at least one pregnancy. Data were retrieved from the computerized database of MHS, a 2-million enrollee health maintenance organization operating in Israel. The database was also used to collect data on patients with RA, SLE, and PsA. A total of 182,073 women had at least one indication of pregnancy during the study period. Among them, 546, 270, and 170 were diagnosed with RA, SLE, and PsA, respectively. The proportion of live-born males in 380,472 offspring of women free of these diseases was 51.5 % (95 % CI 51.4-51.7 %). The proportion (95 % CIs) of male offspring born to mothers diagnosed with of RA, SLE, and PsA were 46.3 % (42.3-50.3 %), 51.8 % (46.6-57.0 %), and 50.6 % (42.8-58.5 %), respectively. Our findings support the primary contribution of the hormonal phenotype rather than the genetic phenotype on autoimmunity. Neither patients with SLE or RA differ from the general population by the sex of their offspring.

Prevalence and factors associated with resistant hypertension in a large health maintenance organization in Israel.

Previous assessments of the prevalence of resistant hypertension (RH) in uncontrolled blood pressure (BP) have ranged from 3% to 30%. Using real-world data, our aim was to estimate the prevalence of RH in patients belonging to the Maccabi Healthcare Services, a 2-million-member health organization in Israel. From 2010 to 2011, all hypertensive patients with ≥2 recorded BP measurements during a minimum period of 6 months were identified. Patients were considered uncontrolled if their most recent BP during the study period and their mean systolic BP or diastolic BP during a preceding period of ≥6months were systolic BP ≥140 mm Hg or diastolic BP ≥90 mm Hg, or systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg in chronic kidney disease or diabetes mellitus. Uncontrolled patients taking diuretics and ≥2 antihypertensive therapy classes at their maximal recommended dose were regarded as resistant hypertensives. A total of 172 432 patients were eligible for the study. Uncontrolled BP was found in 35.9% (n=65 710). Overall, 2.2% of the uncontrolled patients (n=1487) were resistant hypertensives. Patients with RH were characterized by a significantly (P<0.01) older age, higher body mass index, and multicomorbidity (including dyslipidemia, diabetes mellitus, and impaired renal function) compared with patients with controlled hypertension receiving equivalent treatment. The results of this large population-based study indicate a substantially lower prevalence of RH than previously reported. Most patients with uncontrolled BP took less than the maximal recommended antihypertensive treatment.

Trends in statin therapy initiation during the period 2000-2010 in Israel.

PURPOSE: The aim of this population-based study is to describe trends in the characteristics and treatment patterns of statin initiators over the first decade of the 21st century. METHODS: New statin use was studied retrospectively using the database of Maccabi Healthcare Services (MHS), a large Israeli health maintenance organization. Statin initiators were defined as MHS members aged ≥ 30 years who first purchased statins between 2000 and 2010. The starting dose was calculated in simvastatin equivalents based on the World Health Organization's daily defined dose index. Persistence was calculated as the percentage of days covered (PDC) with statins during the first year of therapy. RESULTS: Statin initiation peaked in 2005 and decreased from 38.6 to 18.6 per 1,000 in the period 2005-2010. The average age at therapy initiation decreased from 58.9 (± 12.0) to 54.5 (± 11.7) years, and the average (SD) baseline low-density lipoprotein cholesterol (LDL-C) decreased from 4.2 (± 1.1) to 4.0 (± 0.9) mmol/l during the study period. Women were on average 3 years older than men at treatment initiation, with a higher baseline LDL-C. Among statin initiators, the prevalence of ischemic heart disease (IHD) decreased from 17.8 to 6.7 %, and diabetes prevalence increased from 8.6 to 15.7 %, peaking in 2008 (18.0 %). The PDC with statins ranged between 52.9 and 57.7 %. Simvastatin use at initiation increased from 27.5 % in 2000 to >90 % since 2002. Starting dose increased from 18.5 (± 8.9) to 24.3 (± 13.7) mg simvastatin equivalent. CONCLUSIONS: Among the study population, statin initiators were increasingly characterized by a lower cardiovascular risk-namely, younger individuals without IHD and with a lower baseline LDL-C. These trends underscore the important shift towards statin initiation for primary prevention, as well as the need to balance between benefits and the potential side effect of statins.

Red blood cell distribution width and the risk of cardiovascular morbidity and all-cause mortality. A population-based study.

Red blood cell distribution width (RDW) has been shown to predict cardiovascular mortality in various populations, but studies were less conclusive regarding cardiovascular morbidity. We aimed at evaluating the prognostic effect of RDW on cardiovascular morbidity and all-cause mortality in the largest community cohort to date.We utilised the computerised database of a large community based healthcare maintenance organization (HMO) in Israel to identify a cohort of 225,006 eligible patients aged 40 or above who performed a blood count during 2006. We evaluated the relationship between 1% increments of RDW values and major cardiovascular events and all-cause mortality over a period of five years. A total of 21,939 incident cases of a major cardiovascular event and 4,287 deaths were documented during a total of six years of follow up, respectively. In comparison with patients with RDW level <13%, the hazard ratio for total mortality gradually increased to 4.57 (95% confidence interval [CI]: 3.35-6.24, p<0.001) among male patients and to 3.26 (95% CI: 2.49-4.28, p<0.001) among female patients with a RDW of 17% or above. Similar results were evident in anaemic and non-anaemic populations. RDW above 17% was also associated with a modest increased risk of major cardiovascular events in females 1.26 (95% CI: 1.03-1.52, p=0.021), while in men it was not significant, 1.08 (95% CI: 0.82-1.41, p=NS). In conclusion, increasing RDW levels significantly increased risk of cardiovascular morbidity and all-cause mortality. Our observation is evident in both anaemic and non-anaemic patients.

Hemoglobin nonrecovery following acute myocardial infarction is a biomarker of poor outcome: a retrospective database study.

BACKGROUND: Anemia on admission and during hospitalization is associated with poor short and long term prognosis among patients with acute coronary syndrome (ACS). Our objective was to examine the prognostic implications of longitudinal hemoglobin (Hb) levels following a first acute myocardial infarction (AMI). METHODS: We utilized data obtained from the computerized database of a large community based health care maintenance organization to identify patients who survived for at least 6 months following a first AMI, during the years 2003-2010. Hazard ratios were calculated using Cox proportional regression models with various Hb measurements as dependent variables, and net reclassification improvement (NRI) was applied to evaluate the prognostic usefulness of these Hb measurements. RESULTS: Last Hb measurement during a 6-24 month follow-up period was found to have the highest prognostic power. In males, Hb levels below 13 g/dL were gradually associated with a higher risk of events, reaching a HR of 4.13 at Hb levels <11 g/dL. In females, only Hb levels lower than 11 g/dL were significantly associated with a higher event rate (HR=2.42, p=0.003). Hb decrease was significantly associated with an increased risk in both genders, even among non-anemic patients at baseline. CONCLUSIONS: Anemia and Hb decrement following a first AMI are associated with worse prognosis and elevated risk of combined all cause mortality and recurrent cardiac events.

A population based study of the epidemiology of Herpes Zoster and its complications.

OBJECTIVES: To assess the incidence of Herpes Zoster (HZ) and its complications in the Israeli general population and specifically in immune-compromised individuals, and to identify risk factors for developing HZ and post-herpetic neuralgia (PHN). METHODS: A retrospective database search for newly diagnosed cases of HZ and of PHN during 2006-2010 was conducted using the comprehensive longitudinal database of Maccabi Health Services. Cox-proportional hazards models were used to assess associations between risk factors and HZ and PHN. RESULTS: During 2006-2010 there were 28,977 newly diagnosed cases of HZ and 1508 newly diagnosed cases of PHN. Incidence density rate of HZ was 3.46 per 1000 person-years in the total population and 12.8 per 1000 person-years in immune-compromised patients. HZ and PHN incidence increased sharply with age. 12.4% and 3.1% of elderly HZ patients (≥ 65 years) developed PHN or ophthalmic complications, respectively. In multivariable analyses, HZ and PHN were associated with female sex, higher socioeconomic status, diabetes mellitus, cancer history, and HIV treatment. CONCLUSIONS: Extrapolating to the entire Israeli population, we estimate over 24,000 new cases of HZ and 1250 new cases of PHN each year. Cost-effectiveness analysis should be performed to determine the threshold age for vaccination against HZ.

Thrombosis following acute cytomegalovirus infection: a community prospective study.

Infection might be associated with increased risk of venous thromboembolism (VTE) and arterial thrombosis. Specific hypotheses have been raised regarding the procoagulant response induced by acute cytomegalovirus (CMV) infection. Accordingly, we investigated the 6-month incidence of VTE and/or arterial thrombosis in patients that had been tested positive for CMV-IgM antibodies in a large health maintenance organization. Logistic regression analysis was used to identify independent risk factors for VTE and arterial thrombosis. Among 90,515 patients eligible for the VTE analysis and 90,805 patients eligible for the arterial thrombosis analysis, 6,205 (6.9%) and 6,222 (6.9%) patients were tested positive for CMV-IgM antibodies, respectively. During 6 months of follow-up from index date, the incidence rates per 1,000 capita of VTE among CMV-IgM seropositive and CMV-IgM seronegative patients were 3.06 (19 patients) and 1.36 (115 patients), respectively (odds ratio (OR) 2.25; 95% confidence intervals (95% CI) 1.38-3.66; p = 0.003). CMV-IgM seropositivity was independently associated with VTE appearance (OR 2.49; 95% CI 1.53-4.06; p < 0.0001) following adjustment for age, sex, and other confounders. The incidence rates per 1,000 capita of arterial thrombosis among CMV-IgM seropositive and CMV-IgM seronegative patients were 1.12 (7 patients) and 1.06 (90 patients), respectively (OR 1.06; 95% CI 0.49-2.28; p = 0.840). CMV-IgM seropositivity was not associated with arterial thrombosis. We conclude that acute CMV infection might be associated with an increased short-term VTE risk. To the best of our knowledge, this is the largest study ever to confirm this association.

Continuation of statin therapy and primary prevention of nonfatal cardiovascular events.

Although the beneficial effect of statins in secondary prevention of cardiac events is well established, their effectiveness in primary prevention is questionable when most evidence derives from randomized controlled trials and not "real-life" data. To evaluate the association between persistent use of statins and risk of acute nonfatal cardiovascular events in primary prevention patients in community settings, we retrospectively analyzed a cohort of 171,535 adults 45 to 75 years old with no indication of cardiovascular disease who began statin therapy from 1998 to 2009 in a large health maintenance organization in Israel. Persistence with statins was measured by the proportion of days covered with dispensed prescriptions of statins during the follow-up period. Main outcome measurements were occurrence of myocardial infarction or performance of a cardiac revascularization procedure. Incidence of acute cardiovascular events during the follow-up period (993,519 person-years) was 10.22 per 1,000 person-years. Persistence with statins was associated with a lower risk of incident cardiac events (p for trend <0.01). The most persistent users (covered with statins for ≥80% of their follow-up time) had a hazard ratio of 0.58 (95% confidence interval 0.55 to 0.62) compared to nonpersistent users (proportion of days covered <20%). Similar results were found when analyses were limited to patients with >5 years of follow-up. Treatment with high efficacy statins was associated with a lower risk of cardiac events. In conclusion, our large and unselected community-based study supports the results of randomized controlled trials regarding the beneficial effect of statins in the primary prevention of acute cardiac events.

Psoriasis and cardiovascular risk factors: a case-control study on inpatients comparing psoriasis to dermatitis.

BACKGROUND: Previous reports demonstrated an association between psoriasis and cardiovascular disease (CVD) risk factors. However, most of these studies were based on computerized databases of outpatient clinics, which, because of International Classification of Diseases, Ninth Revision coding issues, require validation of the diagnosis of psoriasis. OBJECTIVE: We sought to study associations between psoriasis and CVD risk factors among psoriatic inpatients compared to inpatients with dermatitis. METHODS: A case-control study was performed using computerized medical databases from the Department of Dermatology at Rabin Medical Center in Israel. Inpatients given the diagnosis of psoriasis were compared with inpatients given the diagnosis of forms of dermatitis for the prevalence of smoking, obesity, diabetes, hypertension, hyperlipidemia, and CVD. Logistic regression models were used for multivariate analyses. RESULTS: The study included 1079 inpatients with psoriasis and 1079 age- and gender-matched inpatients with dermatitis (control patients). A multivariate logistic regression model demonstrated that psoriasis is an independent risk factor for diabetes (odds ratio [OR] 1.43; 95% confidence interval [CI] 1.17-1.75), hypertension (OR 1.31; 95% CI 1.09-1.58), obesity (OR 1.32; 95% CI 0.99-1.76), and smoking (OR 1.38; 95% CI 1.10-1.73). Development of CVD was not significantly associated with psoriasis when correcting for diabetes, obesity, and hypertension. LIMITATIONS: Our study group was composed of inpatients only, which may be biased toward more elderly patients with severe psoriasis who may have consumed systemic treatment including immunosuppressants. CONCLUSIONS: Our study supports previous reports of an association between psoriasis and CVD risk factors, suggesting that the inflammatory process in psoriasis, but not in dermatitis, may have a systemic impact resulting in development of CVD risk factors.

The effect of exercise cessation on non-articular tenderness measures and quality of life in well-trained athletes.

BACKGROUND: The term chronic multi-symptom illness (CMI) refers to a spectrum of pain disorders, such as fibromyalgia and chronic fatigue syndrome, that are characterized by unexplained chronic pain, fatigue, and cognitive and mood complaints OBJECTIVES: To examine the hypothesis that exercise cessation is associated with symptoms similar to CMI in well-trained amateur athletes. METHODS: The study, conducted in running and triathlon clubs in Israel, involved 26 asymptomatic healthy athletes who regularly exercise 6.75 +/- 3.65 hours a week. All athletes were instructed to refrain from physical activity for 7 days. All underwent a complete physical exam, rheumatological assessment including non-articular tenderness threshold (using dolorimeter) and tender points. In addition they completed the SF-36 quality of life questionnaire. Assessments were conducted before exercise cessation and 7 days later. RESULTS: Seven days after sports deprivation all subjects were significantly more tender by all tender measures (P < 0.001) (dolorimeter thresholds and tender point count). There was also a significant reduction in the scores for physical role function (P < 0.001), emotional role function (P < 0.001) and summary subscales of the SF-36 questionnaire after exercise cessation. CONCLUSIONS: Exercise deprivation is associated with change in non-articular tenderness threshold and reduction in quality of life scores. This may be associated with the development of chronic multi-symptom illness.

Psoriasis associated with hepatitis C but not with hepatitis B.

PURPOSE: To investigate the association between psoriasis and viral hepatitis. METHODS: Psoriasis patients were compared to controls regarding the prevalence of viral hepatitis in a case-control study using logistic multivariate models. The study was performed utilizing the medical database of Clalit Health Services. RESULTS: The study included 12,502 psoriasis patients >20 years old and 24,287 age- and sex-matched controls. The prevalence of hepatitis C in patients with psoriasis was increased compared to the prevalence in controls (1.03 vs. 0.56%; p < 0.001). In a multivariate analysis, psoriasis was associated with hepatitis C. An interaction with smoking was noted (smokers: odds ratio, OR = 1.93, 95% confidence interval, CI = 1.30-2.67; nonsmokers: OR = 2.22, 95% CI = 1.63-3.04). The prevalence of hepatitis B in patients with psoriasis was higher than in the controls (0.74 vs. 0.56%; p = 0.043). However, in a multivariate analysis psoriasis was not associated with hepatitis B (OR = 1.22, 95% CI = 0.93-1.60, p = 0.15). CONCLUSION: Our observation supports previous reports of an association between psoriasis and hepatitis C but not with hepatitis B. Physicians who care for patients with psoriasis should be aware of this possible association and consider screening patients with psoriasis for hepatitis C.

Psoriasis and hypertension: a case-control study.

In recent years, numerous reports have demonstrated an association between psoriasis and metabolic syndrome. However, some studies failed to demonstrate an association between psoriasis and hypertension. The aim of the present study was to examine the association between psoriasis and hypertension. Psoriasis patients of a health-maintenance organization were compared with enrollees without psoriasis regarding the prevalence of hypertension in a case-control study. The study included 12,502 psoriasis patients over the age of 20 years and 24,285 age- and sex-frequency-matched controls. The prevalence of hypertension was significantly higher in psoriasis patients than controls (38.8%, 29.1%, respectively, p<0.001). In a multivariate analysis, hypertension was associated with psoriasis after controlling for age, sex, smoking status, obesity, diabetes, non-steroidal anti-inflammatory drugs (NSAIDs) and use of Cox-2 inhibitors (odds ratio: 1.37, 95% confidence interval: 1.29-1.46). The results of this study support the previously noted association between psoriasis and hypertension. We suggest that patients with psoriasis should be routinely screened for the presence of hypertension.
