FDCPs and Insufficient We found no studies meeting inclusion/exclusion criteria that provided evidence Dual Therapy to determine whether there are subgroups of patients based on demographics purchase viagra sublingual 100mg line erectile dysfunction electric pump, comorbidities viagra sublingual 100mg with amex impotence with gabapentin, or other medications for which newer diabetes medications differ from each other in efficacy/effectiveness or frequency of adverse events Abbreviations: FDCP, fixed-dose combination product; HbA1c, OR, odds ratio; RCT, randomized controlled trial; RR, relative risk, SE, standard error; TZD, thiazolidinedione; WMD, weighted mean difference. CONCLUSIONS All of the included medications were efficacious for reducing HbA1c and none of the newer medications appear to cause weight gain. Little data was available to evaluate the long-term effectiveness of the newer medications compared with more established treatments, limiting our ability to determine how to best incorporate newer medications into clinical practice.

Lamotrigine (2 trials), and not carbamazepine (1 trial), was associated with a significantly higher odds of rash relative to placebo (odds ratio 2. Carbamazepine (2 trials), and not gabapentin (1 trial) or lamotrigine (3 82, 86, 163 trials), was more likely than placebo to be associated with somnolence (odds ratio 2. Valproate (1 trial), and not lamotrigine (1 trial), was associated with significantly higher odds of tremor compared with placebo (odds ratio 4. Only valproate was reported to cause weight gain as an adverse event (odds ratio 3. In 31 evaluable patients, lamotrigine was associated with weight loss (mean change from baseline at 6 weeks, –0. There was no significant difference between lamotrigine and placebo (–0. The findings should be interpreted with caution, since they were not based on randomized patients. Key Question 3 Are there subgroups of patients based on demographics (age, racial groups, and gender), other medications, or comorbidities for which one antiepileptic drug is more effective or associated with fewer adverse events? Bipolar disorder Patient characteristics Subtype A fair-quality trial in a hospitalized inpatient population evaluated possible predictors of clinical 97 response to lamotrigine and gabapentin in 45 patients with bipolar or unipolar mood disorder. Responder rates were higher for lamotrigine (51%) than gabapentin (28%) or placebo (21%). Univariate analyses and linear regression showed that response to lamotrigine may be better in male patients with fewer trials of prior medications. A better response to gabapentin appeared to occur in younger patients with lower baseline weight; however, there was no statistically significant difference in response between gabapentin and placebo. These results should be considered preliminary because of the post hoc subgroup analyses, the small and selective (treatment-refractory) study population, and the heterogeneous patient diagnoses. Another trial showed no demographic factors to be predictors of a differential response between valproate and 62 lithium. However, for patients with bipolar I disorder with recent mania and previous psychiatric hospitalization, valproate was associated with a longer time to depressive relapse 62 than lithium. Two placebo-controlled trials evaluated the impact of bipolar subtype, 1 with carbamazepine and 1 with lamotrigine. The trial evaluating carbamazepine showed no differential effect of bipolar subtype by YMRS total score. However, when depressive symptoms were measured on HAM-D, patients with manic episodes appeared to benefit more greatly from carbamazepine than patients with mixed episode; improved symptoms were not consistently of the same type(s). Similarly, valproate was found to have superior efficacy compared with lithium for patients experiencing mixed manic episodes, while in a systematic review of valproate in Antiepileptic drugs Page 53 of 117 Final Report Update 2 Drug Effectiveness Review Project 15 bipolar disorder, response to the drugs was similar in patients with mania alone. These authors also found that irritability was more responsive to valproate than lithium or carbamazepine. Subgroup analyses by bipolar subtype were performed in a trial that compared lamotrigine with placebo maintenance therapy in patients who had bipolar I or II disorder with rapid cycling. The bipolar II subgroup consistently responded better to lamotrigine than placebo on time to premature discontinuation for any reason, proportion of patients who were stable 162 without relapse for 6 months, and GAS score. However, while time to relapse (the primary efficacy measure) was also longer with lamotrigine than placebo in the bipolar II subgroup (17 weeks compared with 7 weeks), this difference between treatments was not statistically significant (P=0. The bipolar I subgroup showed no significant difference between lamotrigine and placebo for any outcome. According to the authors, this finding was unexpected, since lamotrigine had previously been shown to be effective in bipolar I disorder. A high rate of response to placebo was observed in bipolar I patients and may be a confounder or an indication of other possible confounders. The factors accounting for different responses between the 2 bipolar subtypes need further clarification. Age We found 2 reports on the effect of antiepileptic drugs on symptoms of bipolar disorder in older 14, 164 patients. A pooled analysis evaluated data on 98 patients ≥ 55 years who had been randomized to lamotrigine, lithium, or placebo in these 2 studies of lamotrigine maintenance 164 therapy for which the primary outcome measure was time to intervention for a mood episode. Because the subgroups were small and not stratified at randomization, differences at baseline were present, such as mean lifetime hospitalizations, which were 11. Similar to the findings of the results across all ages, compared with placebo lamotrigine delayed the time to intervention for any mood disorder (manic, mixed manic, or depressive episode), while lithium delayed time to intervention for manic and mixed episodes only.

Calvi2 1Division of Hematology/Oncology and 2Division of Endocrinology, Department of Medicine, Wilmot Cancer Center, University of Rochester School of Medicine, Rochester, NY The BM microenvironment and its components regulate hematopoietic stem and progenitor cell (HSC) fate. An abnormality in the BM microenvironment and speciﬁc dysfunction of the HSC niche could play a critical role in initiation, disease progression, and response to therapy of BM failure syndromes. Therefore, the identiﬁcation of changes in the HSC niche in BM failure syndromes should lead to further knowledge of the signals that disrupt the normal microenvironment. In turn, niche disruption may contribute to disease morbidity, resulting in pancytopenia and clonal evolution, and its understanding could suggest new therapeutic targets for these conditions. In this chapter, we brieﬂy review the evidence for the importance of the BM microenvironment as a regulator of normal hematopoiesis, summarize current knowledge regarding the role of dysfunctions in the BM microenvironment in BM failure syndromes, and propose a strategy through which niche stimulation can complement current treatment for myelodysplastic syndrome. Disorders of hematopoiesis Learning Objectives continue to have suboptimal clinical outcomes, highlighting the ● To understand the deﬁnition and current constituents of the appeal of potential therapeutic manipulation of the MME in these HSC niche in the BM situations. Aplastic anemia (AA) is a disorder of the BM that Initial studies supported the central role of bone constituents in HSC results in the loss of its ability to produce mature blood cells. The study of therapeutic targets in AA has been it became clear that the differentiation stage of mesenchymal cells is limited by its rarity in the general population and the dearth of critical for their ability to support and regulate HSCs. The myelodysplastic syndromes heterogeneity of the BM endothelium has been elucidated. In contrast to AA, data suggest that to be found in close association with arterial structures located at the incidence of MDS is increasing. In the literature, and mortality results from the ineffective nature of the malignant this cell population is inconsistently deﬁned, in part because of the clonal hematopoiesis and its suppression of residual normal hemato- lack of consensus on its deﬁning features (adherence to plastic vs poiesis. All types of cytopenias are common among patients with functional characteristics vs phenotypic markers) and the fact that both AA and MDS and are associated with symptomatic anemia, the MSC abbreviation is also used to designate heterogeneous bleeding, and infections. A large proportion of elderly patients with preparations of human mesenchymal stromal precursor cells. Moreover, to date, the circadian rhythms,22 hormonal signals,23-25 oxygen tension,26 and overwhelming majority of effort expended studying MDS has likely other physiologic stimuli. Deﬁnition of the HSC niche in largely ignored the mechanisms by which the MDS clone alters its humans remains less understood than that in mice; however, both local microenvironment and suppresses residual normal BM func- osteoblastic5 and mesenchymal stromal cells have been demon- tion. In this chapter, we review the current understanding of the strated to increase HSC support ex vivo. Compared with controls, MSCs from patients with AA have aberrant morphology, decreased proliferation and clonogenic potential, and increased apoptosis. Relative to normal MSCs, those from AA patients were more difﬁcult to induce to differentiate into osteoblasts and were more readily induced to differentiate into adipocytes. In addition to the abnormal biological features, the transcriptome of MSCs from AA patients demonstrated the down-regulation of numerous genes, including mediators of cell cycling, cell division, proliferation, chemotaxis, and hematopoietic cell interactions, and the up- regulation of genes involved in apoptosis, adipogenesis, and the immune response were up-regulated in MSCs from AA patients. T lymphocytes modulate some aspects of hormonal regulation of the HSC niche. For simplicity, only altered T-cell signaling in AA contributes to abnormal MSC some MME cell types are depicted. Pericytes (PC), macrophages (Mø), regulation is, to our knowledge, an unexplored and as yet unan- endothelial cells (EC), T cells (T), and osteoblasts (OB) are supportive of swered question. HSCs under normal conditions, whereas adipocytes (AC) have an inhibitory role. Frequently cited as some of the strongest evidence for MME dysfunction in MDS contributing to disease initiation and progres- regulation has already found clinical relevance, as illustrated by de sion, Raaijmakers et al showed that deletion of Dicer1 in murine Lima et al, who found that, in patients receiving cord blood osteoprogenitors results in the development of dysplastic hematopoi- transplantations for hematologic malignancies, engraftment was esis with an MDS-like phenotype. The Dicer1 deletion leads to faster and more robust after coculturing the cord blood cells with decreased Sbds [the gene mutated in Shwachman–Diamond syn- BM mesenchymal stromal cells. The Dicer1-null murine model of MDS resulted in primary potential therapeutic intervention in hematopoietic regeneration MME dysfunction, leading to the secondary development of (Figure 1). Moreover, the concept of the niche allows for a unique hematologic malignancy, thus supporting the concept of niche- frame of reference when considering initiation of hematopoietic initiated oncogenesis. Therefore, data support the concept that defects in the MME can be BM microenvironment and initiation of BM initiating steps in the pathogenesis of BM failure syndromes. AA is failure syndromes a paradigm for this concept because microenvironmental dysfunc- Murine models have demonstrated that disruption of the MME can tion, likely mediated at least in part by autoimmunity, is thought to initiate myeloproliferative disease30,31 and even leukemia.
