Conradt et al.\nIncreased Prevalence of Polyneuropathy in PD\n\nAbstract\nBackground:\nThe independent contribution of levodopa exposure and Parkinson’s disease (PD) to the risk of polyneuropathy is not established.\n\nObjective:\nThis study investigated whether patients with newly diagnosed PD without previous exposure to antiparkinsonian drugs have higher prevalence of polyneuropathy than the general population.\n\nMethods:\nUsing the UK General Practice Research Database, presence of polyneuropathy in the previous 3 years was assessed.\n\nResults:\nOf 5089 PD patients and 19,897 controls, polyneuropathy was confirmed in 15 PD patients (0.29% ) and 24 controls (0.12% ). Polyneuropathy prevalence was 2.4-fold higher in PD patients than controls.\n\nConclusions:\nIn this observational study, PD patients had a higher prevalence of preexisting polyneuropathy that cannot be explained by adverse effects of antiparkinsonian drugs.\n\nINTRODUCTION\nPrevious studies have reported a higher prevalence of polyneuropathy in patients with Parkinson’s disease (PD) than in control subjects due to vitamin B12 deficiency caused by levodopa exposure [1–4]. It has been noted that, due to the high correlation between cumulative levodopa exposure and PD severity, separating the role of these two factors on the risk of neuropathy is challenging [5]. To address this methodological problem, the present study aimed to investigate whether patients with newly diagnosed PD (i.e., those patients without a history of exposure to antiparkinsonian drugs) have a higher prevalence of polyneuropathy (PNP) than that observed in general population controls without PD.\n\nMETHODS\n\nStudy design and data source\nIn this population-based observational study, patients with newly diagnosed PD and matched controls without PD were compared with respect to the presence of PNP in the previous 3 years. Data source was the UK General Practice Research Database (GPRD), consisting of the electronic patient records of about 10 million patients from more than 500 general practices in the United Kingdom. A number of observational studies in PD patients were performed with the GPRD [6], and several validation studies have demonstrated completeness and validity of the database [7, 8]. The study was reviewed for ethical and scientific merit, and was approved by the Independent Scientific Advisory Committee of the GPRD.\n\nIdentification of PD patients and controls\nFor PD patients, the date of the first diagnosis of PD was defined as the index date. Inclusion criteria indicated that patients: (1) had to be at least 18 years of age, (2) had at least 3 years of available person-time before the index date, (3) had not received more than one anti-Parkinsonian drug prescription in the 3 years before the index date, and (4) had at least two prescriptions of anti-Parkinsonian drugs after the index date. For each PD patient, up to four controls without PD were matched by sex, age, and general practice. Exclusion criteria indicated that patients: (1) had medical conditions known to be associated with neuropathy (e.g., diabetes, alcohol abuse), (2) were prescribed drugs known to cause neuropathy within 3 years before the index date, and (3) were prescribed drugs known to cause Parkinsonism within 180 days preceding the index date.\n\nDefinition and identification of PNP\nIn PD patients and controls, all diagnoses of primary polyneuropathy without an underlying medical condition as well as potential vitamin-deficiency–related neuropathies within 3 years preceding the index date were identified. As previous studies indicated that vitamin B6, vitamin B12, and/or folate deficiencies might play an important role in PD-associated neuropathy [1–4], these types of polyneuropathy were included in the study definition of PNP.\nAll subjects with potential PNP were validated independently and blinded to case status by two physicians (A.M. and C.I.). In the rare case of disagreement, the patient record was discussed between the reviewers. PNP was considered as confirmed, if there was no other compelling reason for PNP and at least one of the following criteria were met: PNP diagnosis was made by a specialist, PNP was a hospital discharge diagnosis, or PNP was diagnosed in the context of nerve conduction studies; there was initiation of treatment for PNP; or PNP diagnosis was repeated in medical records \u003e1 month after initial diagnosis.\n\nStatistical analysis\nConditional logistic regression analysis was used to calculate odds ratios for the association between PNP and PD. As potential confounders were eliminated by study design due to matching and exclusion of other potential causes of polyneuropathy, no other variables were considered. Analyses stratified by sex and age were performed. To evaluate the impact of the validation procedure on the study results, a sensitivity analysis included all potential cases of PNP, irrespective of a diagnosis confirmed in the validation process. In another sensitivity analysis, all person-time prior to the index date (instead of 3 years) was considered to assess presence of PNP. All analyses were performed using SAS 9.1 (SAS Institute Inc., Cary, NC, USA.).\n\nRESULTS\nA total of 5132 patients with incident PD, who fulfilled all inclusion and exclusion criteria were identified. Of these, 5089 patients (99.2%) had at least one matched control and four controls were available for 95.2% PD patients (Table 1).\nTable 1 Demographic characteristics of PD patients and matched controls\nCharacteristic PD patients, n (%) Matched controls, n (%)\n(n = 5089) (n = 19,897)\nMales 3156 (62) 12,261 (61.6)\n  \u003c60 years 383 (7.5) 1530 (7.7)\n  60–69 years 747 (14.7) 2985 (15.0)\n  70–79 years 1206 (23.7) 4761 (23.9)\n≥80 years 820 (16.1) 2985 (15.0)\nFemales 1933 (38.0) 7636 (38.4)\n  \u003c60 years 184 (3.6) 736 (3.7)\n  60–69 years 388 (7.6) 1552 (7.8)\n  70–79 years 724 (14.2) 2876 (14.5)\n  ≥80 years 637 (12.5) 2472 (12.4)\nPD, Parkinson’s disease. A total of 20 PD patients (0.39%) and 40 controls (0.20%) had a diagnosis indicating PNP within 3 years prior to the index date. After manual record review, 15 PD patients and 24 controls were classified as patients with confirmed PNP. The prevalence of PNP was increased 2.4-fold in patients with incident PD compared with general population controls (odds ratio [OR] = 2.41; 95% confidence interval [CI], 1.17–4.81). There was no indication that age or sex acted as effect modifiers, but these analyses were limited by the low number of patients with PNP (Table 2).\nTable 2 Prevalence of PNP in PD patients and matched controls\nCharacteristic No. of PD patients No. of controls with OR (95% CI)\nPNP/total No. of PNP/total No. of\npatients (%) controls (%)\n(n = 5089) (n = 19,897)\nAll patients 15/5089 (0.29) 24/19,897 (0.12) 2.41 (1.17–4.81)\n  \u003c60 years 1/567 (0.18) 0/2266 (0) NC\n  60–69 years 3/1135 (0.26) 5/4537 (0.11) 2.40 (0.37–12.34)\n  70–79 years 6/1930 (0.31) 9/7637 (0.12) 2.67 (0.78–8.39)\n  ≥80 years 5/1457 (0.34) 10/5457 (0.18) 1.81 (0.47–5.91)\nMales 11/3156 (0.35) 15/12,261 (0.12) 2.79 (1.15–6.54)\n  \u003c60 years 0/383 (0) 0/1530 (0) NC\n  60–69 years 3/747 (0.40) 5/2985 (0.17) 2.40 (0.37–12.34)\n  70–79 years 4/1206 (0.33) 5/4761 (0.11) 3.20 (0.64–14.87)\n  ≥80 years 4/820 (0.49) 5/2985 (0.17) 2.76 (0.53–13.21)\nFemales 4/1933 (0.21) 9/7636 (0.12) 1.78 (0.40–6.37)\n  \u003c60 years 1/184 (0.54) 0/736 (0) NC\n  60–69 years 0/388 (0) 0/1552 (0) NC\n  70–79 years 2/724 (0.28) 4/2876 (0.14) 2.00 (0.18–13.96)\n  ≥80 years 1/637 (0.16) 5/2472 (0.20) 0.80 (0.02–7.15)\nCI, confidence interval; PNP, polyneuropathy; NC, not calculated; OR, odds ratio; PD, Parkinson’s disease. The sensitivity analysis that accounted for all potential PNP (irrespective of validation results) revealed similar results (OR = 1.95; 95% CI, 1.08–3.42). The sensitivity analysis that expanded the assessment period for PNP to the total available person-time also revealed results similar to the main analysis (OR = 1.96; 95% CI, 1.23–3.08 for potential PNP and OR = 2.32; 95% CI, 1.19–4.40 for confirmed PNP).\n\nDISCUSSION\nIn this observational study, patients with incident PD had a higher prevalence of preexisting PNP than matched general population controls without PD. Sensitivity analyses revealed that the results were robust with respect to the effects of case validation and with respect to the time window used to account for PNP.\nPrevious studies on the association of PD and polyneuropathy focused on patients with known PD and reported strong associations of levodopa treatment and presence of polyneuropathy in these patients [2–4]. In contrast, the present study considered the person-time before PD treatment was initiated, so that the increased frequency of PNP cannot be explained by adverse effects of anti-Parkinsonian drugs. One study assessed the prevalence of PNP in untreated patients with PD; however, this study did not make comparisons with age-matched patients without PD [2]. Other studies have indicated that there might be a link between disorders of the peripheral nervous system and PD. A case-control study on the history of Bell’s Palsy in patients with incident PD, compared with controls without PD, revealed an increased frequency of Bell’s Palsy in PD patients [9]. A histopathological study revealed that PD patients had a significant loss of epidermal nerve fibers and Meissner corpuscles, compared with healthy controls [10]. Peripheral neuropathy has been described in association with early onset genetic PD due to mutations of the parkin gene [11, 12], which indicates a link between central and peripheral neuronal degeneration at least in these subgroups of PD patients.\nThis observational study has some potential limitations that should be considered. As the assessment of PNP was based on clinical diagnoses, some patients might have been considered as PNP cases by error. However, one would expect the results to be biased towards the null (i.e., no association) in case of non-differential misclassification. The absolute prevalence of PNP in this study was low and most probably, active screening for PNP would have substantially increased the prevalence. This, however, does not explain the increased odds ratio observed in this study. It cannot be excluded that some PD patients were misdiagnosed as having PNP before the diagnosis of PD was made. As the main analysis was based on confirmed PNP, and the extension of the assessment period beyond 3 years revealed robustness of the results, it seems unlikely that this potential source of bias has substantially affected the results. Due to the observational nature of the study, it was not possible to retrospectively classify PNP cases into those with or without causal relationship to vitamin B/folate deficiencies, nor was it possible to perform a sensitivity analysis restricted to PNP cases without relationship to these deficiencies.\nAdditional studies are warranted to better understand the linkage between PD and PNP. A recent study using confocal corneal microscopy demonstrated that newly diagnosed, untreated PD patients had a higher rate of PNP than controls [13], further confirming the results of this observational study. Longitudinal studies using confocal corneal microscopy in patients with PD before and after treatment could help to further elucidate the role of anti-PD treatment in PNP.\n\nCONFLICTS OF INTEREST\nDianlin Guo is an employee of AbbVie Inc., and may hold stock and/or stock options.\nAnca Miclea is an employee of Abbott Laboratories and may hold stock and/or stock options.\nThomas Nisslein is an employee of Abbott Laboratories and may hold stock and/or stock options.
