Lower melatonin level, melatonin receptor gene variations, and atenolol treatment are associated with glucose dysregulation. We investigated whether atenolol‐related glucose and melatonin changes are correlated, and whether single nucleotide polymorphisms (SNPs) in melatonin candidate genes contribute to interindividual variation in glucose change. Hypertensive Caucasians (n = 232) from the Pharmacogenomic Evaluation of Antihypertensive Responses (PEAR) study treated with atenolol for 9 weeks were studied. Urinary 6‐sulfatoxymelatonin (aMT6s) was measured pre‐ and posttreatment and normalized to urinary creatinine. Pharmacogenetic effects on glucose change of 160 SNPs in 16 melatonin candidate genes were assessed with multiple linear regression. Atenolol was associated with increased glucose (1.8 ± 10.1mg/dl, P = 0.02) and decreased aMT6s (–4.5 ± 10.1 ng/mg, P < 0.0001). However, the aMT6s change was not correlated with post‐atenolol glucose change. SNP rs11649514 in PRKCB was associated with glucose change (P = 1.0×10−4). PRKCB is involved in the melatonin‐insulin regulatory pathway, and may be important in mediating clinically meaningful atenolol‐related hyperglycemia.

SummaryObjectiveThere is a complex bidirectional relationship between sleep and epilepsy. Sleep/wake timing of seizures has been investigated for several individual seizure types and syndromes, but few large‐scale studies of the timing of seizures exist in people with varied epilepsy types. In addition, the genetic contributions to seizure timing have not been well studied.MethodsSleep/wake timing of seizures was determined for 1,395 subjects in 546 families enrolled in the Epilepsy Phenome/Genome Project (EPGP). We examined seizure timing among subjects with different epilepsy types, seizure types, epilepsy syndromes, and localization. We also examined the familial aggregation of sleep/wake occurrence of seizures.ResultsSeizures in nonacquired focal epilepsy (NAFE) were more likely to occur during sleep than seizures in generalized epilepsy (GE), for both convulsive (odds ratio [OR] 5.2, 95% confidence interval [CI] 3.59–7.52) and nonconvulsive seizures (OR 4.2, 95% CI 2.48–7.21). Seizures occurring within 1 h of awakening were more likely to occur in patients with GE than with NAFE for both convulsive (OR 2.3, 95% CI 1.54–3.39) and nonconvulsive (OR 1.7, 95% CI 1.04–2.66) seizures. Frontal onset seizures were more likely than temporal onset seizures to occur during sleep. Sleep/wake timing of seizures in first‐degree relatives predicted timing of seizures in the proband.SignificanceWe found that sleep/wake timing of seizures is associated with both epilepsy syndrome and seizure type. In addition, we provide the first evidence for a genetic contribution to sleep/wake timing of seizures in a large group of individuals with common epilepsy syndromes.

AbstractBackgroundA 50% or greater reduction in the frequency of fecal incontinence (FI) recorded with daily bowel diaries is the primary endpoint in clinical trials of FI. Whether this difference is clinically important is unknown. The relationship between FI symptoms recorded with daily and weekly instruments is unknown. The contribution of psychological factors to quality of life (QOL) in FI is unclear.MethodsFecal incontinence severity was assessed with daily bowel diaries and periodic questionnaires (fecal incontinence severity score [FISS], FIQOL, 36‐Item Short Form Health Survey [SF‐36], and hospital anxiety and depression scales) for 4 weeks before and during double‐blind randomization to placebo or clonidine in 44 women with FI. The reduction in FI frequency was compared to the minimal clinically important difference (MCID) computed from the FISS. Endpoints of FI were compared between daily and weekly diaries.Key ResultsThe FISS exceeded the MCID in 75% and 83% of patients in whom the FI frequency declined by 50–74% and ≥75% respectively. Parameters of FI measured with daily and weekly instruments were significantly correlated. The daily parameters explained 71% of the inter‐patient variation in the FISS. The SF‐36 health scores, rather than the FISS rating, explained a majority of the inter‐subject variation in FIQOL.Conclusions & InferencesMost patients who report a ≥50% reduction in FI frequency experience a clinically important improvement. Weekly questionnaires accurately assess the severity of FI. Self‐reported physical and mental health explained a greater proportion of the variance in FIQOL than FI symptom severity.

Background: Anti‐muscle specific kinase antibody positive (MuSK Ab) myasthenia gravis (MG) patients are known to have different clinical course compared to anti‐acetylcholine receptor Ab positive MG patients. Therapeutic plasma exchange (TPE) has been reported to be effective; however, little is known of the response and of TPE procedural information. An ASFA Apheresis Registry was developed to analyze those data. Methods: The study collected detailed de‐identified patient data, TPE procedures, and treatment outcome/complications. Collected data was described in aggregate. Results: A total of 15 MuSK Ab MG patients with exacerbation of MG symptoms, 13 females/2 males, median age 44, were investigated. Thirty TPE courses (median 5 procedures/course, total 145 procedures) were evaluated. All TPE procedures were performed with citrate anticoagulation, 1 − 1.25 plasma volume exchange in 100% fluid balance, and 90% of courses used only albumin as replacement. Calcium was added to albumin or given orally as needed. TPE was performed every other day in 55% of courses. Adverse events occurred in 3.4% of procedures. Ten patients (67%) experienced relapses within a median of 7 weeks. Objective symptoms were resolved in more than 75% of courses. Overall subjective improvement rates were 94.1%/93.3% after 3/4 TPE procedures, respectively. Thirty‐one percent of patients responded poorly with minimal recovery. Conclusion: Overall subjective improvement was seen up to 94% of patients after one course of TPE. Some patients were poor‐responders. Five TPE may be adequate for initial course with additional TPE as needed. Based upon this preliminary data, we will modify our future data collection. J. Clin.

We report the long‐term follow‐up results of a phase II trial of IL‐1 receptor antagonist and low‐dose dexamethasone for early stage multiple myeloma (MM). Patients were eligible if they had smoldering multiple myeloma (SMM) or indolent multiple myeloma (IMM) without the need for immediate therapy. Forty seven patients were enrolled and subsequently treated with IL‐1Ra; in 25/47 low‐dose dexamethasone (20 mg weekly) was added. The primary endpoint was progression‐free survival (PFS). In the clinical trial, three patients achieved a minor response (MR) to IL‐1Ra alone; five patients a partial response (PR) and four patients an MR after addition of dexamethasone. Seven patients showed a decrease in the plasma cell labeling index (PCLI) which paralleled a decrease in the high sensitivity C‐reactive protein (hs‐CRP). The median PFS for the 47 patients was 1116 days (37.2 months). The median PFS for patients without (n = 22) and with (n = 25) a decrease in their baseline hs‐CRP was 326 days (11 months) vs. 3139 days (104 months) respectively (P <0.0001). The median overall survival (OS) for the 47 patients was 3482 days (9.5 years). The median OS for patients without and with a decrease in their baseline hs‐CRP was 2885 days (7.9 years) vs. median not reached, respectively (P = 0.001). In SMM/IMM patients at risk for progression to active myeloma, reduction in the hs‐CRP indicates successful targeting of the IL‐1/IL‐6 axis resulting in improved PFS and OS.(Clinical Trials.gov Identifier: NCT00635154) Am.

AbstractAimClostridium difficile infection (CDI) of the ileal pouch following restorative proctocolectomy (RPC) is becoming increasingly recognized. We aimed to understand better (i) the associated risk factors, (ii) treatment practices and (iii) the pouch diversion and failure rate in patients who developed CDI of the pouch after RPC for ulcerative colitis (UC).MethodPatients who tested positive for C. difficile of the pouch between 2007 and 2010 were included in the analysis. Data collected included patient demographics, time from RPC to documented CDI, the treatment of CDI and rate of excision of the pouch.ResultsOf 2785 patients recorded in the hospital CDI database, 15 had had an RPC with ileal pouch anal anastomosis. The median age was 44 years and the median interval from RPC to first documented episode of CDI was 3 years. Thirteen (81%) patients had had multiple episodes of pouchitis before and after CDI infection, and all were symptomatic at the time of testing for CDI. Within 30 days of the diagnosis of CDI, six (40%) patients were taking immunosuppressive medication, seven (47%) were taking a proton pump inhibitor and 12 (80%) had received antibiotics. Five patients required hospitalization for CDI and four had severe infections characterized by a serum creatinine more than 1.5 times baseline (n = 3) and a white cell count above 15 000 (n = 1). Six patients who underwent endoscopy had severe inflammation of the pouch including the presence of a pseudomembrane in one case. Ten patients were treated with metronidazole alone and five with vancomycin. Two patients had recurrent CDI of the pouch during a median follow‐up period of 2.9 years and one had CDI refractory to medical management. This patient required diversion of the pouch with an ileostomy for refractory CDI but no patient required excision of the pouch.ConclusionAll 15 patients developing CDI of the pouch were successfully treated with antibiotics and only one required surgery in the form of an ileostomy.

Abstract Background In studies of diabetic gastroparesis, patients with type 1 and type 2 diabetes mellitus (T1 DM , T2 DM ) are often combined for analyses. We compared gastroparesis severity, healthcare utilization, psychological function, and quality of life in T1 DM vs T2 DM gastroparesis patients. Methods Questionnaire, laboratory, and scintigraphy data from patients with gastroparesis and T1 DM and T2 DM from seven centers of the National Institute of Diabetes and Digestive and Kidney Diseases Gastroparesis Clinical Research Consortium Registry were compared at enrollment and after 48 weeks. Multiple regression models assessed baseline and follow‐up differences between diabetes subtypes. Key Results At baseline, T1 DM patients ( N = 78) had slower gastric emptying, more hospitalizations, more gastric stimulator implantations, higher hemoglobin A1c (HbA1c), and more anxiety vs T2 DM patients ( N = 59). Independent discriminators of patients with T1 DM vs T2 DM included worse gastroesophageal reflux disease, less bloating, more peripheral neuropathy, and fewer comorbidities ( p ≤ 0.05). On follow‐up, gastrointestinal ( GI ) symptom scores decreased only in T2 DM ( p < 0.05), but not in T1 DM patients who reported greater prokinetic, proton pump inhibitor, anxiolytic, and gastric stimulator usage over 48 weeks ( p ≤ 0.03). Gastrointestinal symptoms at baseline and 48 weeks with both subtypes were not associated with HbA1c, peripheral neuropathy, psychological factors, or quality of life. Conclusions & Inferences Baseline symptoms were similar in T1 DM and T2 DM patients, even though T1 DM patients had worse gastric emptying delays and higher HbA1c suggesting other factors mediate symptom severity. Symptom scores at 48 weeks decreased in T2 DM , but not T1 DM patients, despite increased medical and surgical treatment utilization by T1 DM patients. Defining causes of different outcomes in diabetic gastroparesis warrants further investigation.
