Objective: There is evidence that gender and age at onset may have a bearing on schizophrenia. The extent to which this differential age at onset influences the clinical features of schizophrenia and its outcome in males and females is not clear. Method: One hundred and twenty outpatients with DSM-III-R schizophrenia were studied to determine the association of antecedent, historical, clinical and 13–year outcome features with age at onset in females (n = 64) and in males (n = 56). Results: Males were significantly younger at illness onset but were not otherwise different from females in antecedent features of illness. For males, age at onset bore little relationship to outcome after 13 years. Females with early onset of illness were more likely to have experienced obstetric complications, to evidence poorer premor-bid functioning, and to have a worse clinical, social and functional outcome than females with late onset. Conclusions: Even though females may have a more benign illness than males, among females, those with early age at onset may be characterised by neurodevel-opmental deviance and worse illness outcome.

IntroductionAge of onset of illness may be useful in explaining the heterogeneity among older bipolar patients.ObjectiveTo examine the relationship of age of onset with clinical, demographic and behavioral variables, in older patients with bipolar disorder.MethodsThis was a cross-sectional, descriptive and analytical study, including 24 patients suffering from bipolar disorders, aged 65 years or more and followed-up in outpatient psychiatry unit at Hedi Chaker university hospital in Sfax in Tunisia. We used a standardized questionnaire including socio-demographic, behavioral and clinical data. Age of onset was split at age 40 years into early-onset (< 40 years; n = 12) and late-onset (≥ 40 years; n = 12) groups.ResultsThe mean age for the entire sample was 68.95 years. The mean age of onset was 39.95 years. The majority (60%) of patients were diagnosed with bipolar I. Few meaningful differences emerged between early-onset and late-onset groups, except that tobacco use was significantly higher in the late-onset group (66.6% vs. 16.6%; P = 0.027). No significant differences between the early-onset and late-onset groups were seen on demographic variables, family history and number of medical diagnoses or presence of psychotic features.ConclusionOur study found few meaningful behavioral differences between early versus late age at onset in older adults with bipolar disorder.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Background. Substantial variability in age at onset of illness and course of illness exists between patients with schizophrenia. Recent studies suggest that age at illness onset may be useful in defining biologically and clinically distinct subgroups of patients.Methods. Two hundred and ten males with schizophrenia were classified as early-onset or adult-onset according to their age at first hospitalization. Birth history, clinical functioning and treatment response was assessed in a subgroup of patients. Brain anatomy was assessed from CT scans in all patients and in 32 non-psychiatric control subjects.Results. Patients with an early-onset were likely to have a history of obstetric complications, a poor response to neuroleptic treatment, and showed no relationship between ventricle size and duration of illness. Adult-onset patients were less likely to have obstetric complications, more likely to respond to treatment in the first years of illness, and showed an association between brain structure and duration of illness.Conclusions. The distinction between early- and adult-onset patients may have important aetiological and treatment implications.

One hundred and seven newly diagnosed, untreated patients with Parkinson's disease (PD) were divided into two groups according to their age at reported onset of symptoms. Of these, 79 patients were under age 70 (early-onset) and 28 patients were age 70 and over (late-onset). The group of 50 control subjects comprised spouses, friends of the PD patients, and community volunteers. The patients were participants in a multicenter drug study of Parkinson's disease. Each had received a detailed neurological and neuropsychological assessment in the baseline placebo phases of the study. Thirty-4 patients with early-onset and 12 patients with late-onset were reassessed 3 years after treatment with low-dose levodopa, with bromocriptine, or with a combination of the two drugs. The results of the baseline phase of the study revealed that 8% of the early-onset group and 32% of the late-onset group were classified as demented. The 3-year follow-up revealed that the prevalence of dementia had increased to 17% in the early-onset group and to 83% in the late-onset group. This study confirms that at least two distinct subtypes of Parkinson's disease exist. The subtypes differ both clinically and neuropsychologically. The age at onset of symptoms is a critical determinant of the rate and type of cognitive decline in Parkinson's disease.

ObjectiveTo describe the characteristics of patients with very-late-onset myasthenia gravis (MG).MethodsThis observational cross-sectional multicenter study was based on information in the neurologist-driven Spanish Registry of Neuromuscular Diseases (NMD-ES). All patients were >18 years of age at onset of MG and onset occurred between 2000 and 2016 in all cases. Patients were classified into 3 age subgroups: early-onset MG (age at onset <50 years), late-onset MG (onset ≥50 and <65 years), and very-late-onset MG (onset ≥65 years). Demographic, immunologic, clinical, and therapeutic data were reviewed.ResultsA total of 939 patients from 15 hospitals were included: 288 (30.7%) had early-onset MG, 227 (24.2%) late-onset MG, and 424 (45.2%) very-late-onset MG. The mean follow-up was 9.1 years (SD 4.3). Patients with late onset and very late onset were more frequently men (p < 0.0001). Compared to the early-onset and late-onset groups, in the very-late-onset group, the presence of anti–acetylcholine receptor (anti-AChR) antibodies (p < 0.0001) was higher and fewer patients had thymoma (p < 0.0001). Late-onset MG and very-late-onset MG groups more frequently had ocular MG, both at onset (<0.0001) and at maximal worsening (p = 0.001). Although the very-late-onset group presented more life-threatening events (Myasthenia Gravis Foundation of America IVB and V) at onset (p = 0.002), they required fewer drugs (p < 0.0001) and were less frequently drug-refractory (p < 0.0001).ConclusionsPatients with MG are primarily ≥65 years of age with anti-AChR antibodies and no thymoma. Although patients with very-late-onset MG may present life-threatening events at onset, they achieve a good outcome with fewer immunosuppressants when diagnosed and treated properly.

Abstract Background Eczema is a common inflammatory skin disease with varying developmental trajectories/patterns. This study sought to investigate eczema development from infancy to early adulthood by identifying distinct developmental trajectories that describe disease patterns over time and evaluate the role of early life risk factors. Methods The Isle of Wight Birth Cohort (n = 1456) was prospectively assessed at birth, 1, 2, 4, 10, 18, and 26 years. At each assessment, eczema was ascertained based on established clinical criteria. Developmental trajectories of eczema between 1-or-2 and 26 years were identified separately for males and females by applying semiparametric mixture models. Associations were assessed by applying a modified Poisson regression to estimate adjusted risk ratios (aRR) and 95% confidence intervals (CI). Results In both males and females, the following eczema trajectories were identified: unaffected/transient (77.7% vs. 73.0%), mid-onset late-resolving (7.8% vs. 4.4%), late-onset (5.2% vs. 9.5%), and early-onset persistent (9.3% vs. 5.4%). In females, an additional trajectory was identified: early-onset early-resolving (7.7%). Among males, filaggrin gene (FLG) variants (aRR = 2.45, 95% CI: 1.34-4.46) and paternal eczema (2.66, 1.39-5.08) were associated with the early-onset persistent trajectory. Among females, maternal eczema (2.84, 1.42-5.70) and high birthweight (2.25, 1.08-4.69) were associated with the early-onset persistent trajectory. Conclusions Four and five trajectories represented eczema development among males and females, respectively, with different predisposing risk factors. Key messages Males and females may experience a different course of eczema and also sex-specific risk factors.

Fifty-six neonates with enterococcal septicemia in a single hospital from 1977 through 1986 were studied. The incidence was low and constant until 1983, when an increase, attributable to infections in infants older than 7 days of age (late-onset), was noted. These infants were more premature (mean gestational age 29.5 vs 36.9 weeks) and had lower birth weights (mean 1250 vs 2700 g) than those with early-onset enterococcal sepsis, and in most the infections were characterized by a nosocomial origin. Infants with early-onset infection had a mild illness with respiratory distress typical of other etiologic agents or diarrhea without focal infection. By contrast, late-onset enterococcal sepsis was heralded by severe apnea, bradycardia, circulatory collapse, and increased ventilatory requirements. Focal infections, including scalp abscess or catheter-related infection (23% each), meningitis or pneumonia (15% each), were common. Rapid clinical improvement and clearance of bacteremia resulted from therapy with an aminoglycoside and either ampicillin or vancomycin, but only if abscesses were drained and intravascular catheters were removed. Mortality rates for early-onset, late-onset, and necrotizing entercolitis-associated infection were 6, 8, and 17%, respectively. Enterococcus is a frequent cause of late-onset septicemia in premature neonates, and empiric therapy should include appropriate antimicrobial agents.

AbstractIntroductionTo determine the influence of ethnicity on the age at onset (AAO) and further understand the significance of AAO as a clinical marker of bipolar and schizoaffective disorders.MethodsAdmixture analysis was used to identify sub-groups characterized by differences in AAO. Differences in clinical features were analyzed for these sub-groups using multivariate logistic regression. Comparisons were made with previous studies using the 2-Sample Kolmogorov-Smirnov Test.ResultsAdmixture analysis yielded a combination of 2 normal theoretical distributions with means (SD) of 16.9 (3.6) for the early-onset sub-group and 24.4 (9.2) years for the late-onset sub-group. The sub-groups were divided by a cut-off of 22 years. There were significant differences between the early and late onset bipolar patient populations regarding substance abuse comorbidity (P=.044) and psychotic features (P=.015). Ethnicity did not have a significant influence on the AAO.DiscussionThe associations between early-onset and higher incidence of psychosis and substance abuse in our sample are consistent with other studies exploring the AAO in bipolar disorder.ConclusionOur findings support the notion of AAO as a clinical marker for the underlying heterogeneity of bipolar spectrum disorders. In particular, we found a strong overlap of early AAO with clinical features associated with greater severity and poor outcome.

Objective.Ankylosing spondylitis (AS) is generally observed in young patients but can occur later in life or in persons ≥ 50 years of age. Our objective was to characterize the clinical features of late-onset AS in a large multicenter national cohort.Methods.We studied late-onset AS in the National Registry of Spondyloarthritis of the Spanish Society of Rheumatology (REGISPONSER database) cohort (n = 1257), of whom 3.5% had onset at age ≥ 50 years versus a control group with onset at < 50 years.Results.There were no differences between late-onset and early-onset AS according to sex and family history of spondyloarthropathies. Patients in the late-onset group more often showed involvement of the cervical spine (22.7% vs 9.7%; p = 0.03) and arthritis of the upper (13.6% vs 3.0%; p = 0.002) and lower limbs (27.3% vs 15.2%; p = 0.03) as first manifestations than did patients in the early-onset group. A higher percentage of mixed forms (axial and peripheral joint disease) during the course of the disease was also recorded in the late-onset group (50% vs 24%; p = 0.0001).Conclusion.Our study suggests that age at onset of AS affects the patients’ presenting clinical form. Arthritis of the upper limbs requires a differential diagnosis with other conditions frequent in patients over 50 years of age, such as rheumatoid arthritis or crystal-induced arthropathy.

Background: Rare variants of SORL1 have been associated with an increased risk of early-onset or late-onset Alzheimer’s disease (AD). However, a lot remains to be clarified about their significance in the pathogenesis of the disease. Objective: To evaluate the role of SORL1 variants among Finnish patients with early-onset AD (EOAD). Methods: The rare SORL1variants were screened in a cohort of 115 Finnish EOAD patients (mean age at onset 58.3 years, range 46–65 years) by using the whole-exome sequencing. Results: We found one novel nonsense variant (p.Gln290 *) and eight missense variants in SORL1. This is the first study reporting the SORL1 variants p.Lys80Arg, p.Ala789Val and p.Arg866Gln in EOAD patients. Furthermore, two of these three missense variants were overrepresented in EOAD patients compared to gnomAD non-neuro Finnish samples. Conclusion: This study strengthens the earlier findings, that the rare variants in SORL1 are associated with EOAD.

Abstract Background: Accumulating evidence has revealed that immunity plays an important role in amyotrophic lateral sclerosis (ALS) progression. However, the results regarding the serum levels of immunoglobulin and complement are inconsistent in patients with ALS. Although immune dysfunctions have also been reported in patients with other neurodegenerative diseases, few studies have explored whether immune dysfunction in ALS is similar to that in other neurodegenerative diseases.Methods: Serum levels of immunoglobulin and complement were measured in 245 patients with ALS, 65 patients with multiple system atrophy (MSA), 60 patients with Parkinson’s disease (PD), and 82 healthy controls (HCs). A meta-analysis including data from this study was performed to evaluate the differences in the levels of immunoglobulin and complement between ALS patients and HCs. The serum levels of immunoglobulin and complement were compared between patient groups and HCs or between ALS patient groups established by age at onset, site at onset, disease duration, or disease severity. The correlations between the levels of immunoglobulin and complement and the clinical characteristics of ALS were analysed using Spearman correlation analysis.Results: The pooled results showed that patients with ALS had higher C4 levels than did HCs, and no significant differences between these two groups in IgG, IgA, IgM, or C3 levels were found. Multiple comparisons revealed that there were no significant differences between patients with ALS and other neurodegenerative diseases in IgG, IgA, IgM, C3, or C4 levels. In addition, the IgG levels were lower in early-onset ALS patients than in late-onset ALS patients and HCs. The correlations between age at onset of ALS and IgG and IgA levels were significantly positive. Moreover, spinal-onset ALS patients had lower serum IgG levels than did HCs, but no difference was found between bulbar-onset ALS patients and HCs.Conclusions: Peripheral immunity abnormalities existed in patients with ALS, and lower IgG levels were associated with early-onset ALS.
