A systematic review of non-hormonal treatments of vasomotor symptoms in climacteric and cancer patients.

The cardinal climacteric symptoms of hot flushes and night sweats affect 24-93% of all women during the physiological transition from reproductive to post-reproductive life. Though efficacious, hormonal therapy and partial oestrogenic compounds are linked to a significant increase in breast cancer. Non-hormonal treatments are thus greatly appreciated. This systematic review of published hormonal and non-hormonal treatments for climacteric, and breast and prostate cancer-associated hot flushes, examines clinical efficacy and therapy-related cancer risk modulation. A PubMed search included literature up to June 19, 2014 without limits for initial dates or language, with the search terms, (hot flush* OR hot flash*) AND (clinical trial* OR clinical stud*) AND (randomi* OR observational) NOT review). Retrieved references identified further papers. The focus was on hot flushes; other symptoms (night sweats, irritability, etc.) were not specifically screened. Included were some 610 clinical studies where a measured effect of the intervention, intensity and severity were documented, and where patients received treatment of pharmaceutical quality. Only 147 of these references described studies with alternative non-hormonal treatments in post-menopausal women and in breast and prostate cancer survivors; these results are presented in Additional file 1. The most effective hot flush treatment is oestrogenic hormones, or a combination of oestrogen and progestins, though benefits are partially outweighed by a significantly increased risk for breast cancer development. This review illustrates that certain non-hormonal treatments, including selective serotonin reuptake inhibitors, gabapentin/pregabalin, and Cimicifuga racemosa extracts, show a positive risk-benefit ratio. Key pointsSeveral non-hormonal alternatives to hormonal therapy have been established and registered for the treatment of vasomotor climacteric symptoms in peri- and post-menopausal women.There are indications that non-hormonal treatments are useful alternatives in patients with a history of breast and prostate cancer. However, confirmation by larger clinical trials is required.

Eosinophilic esophagitis: red on microscopy, white on endoscopy.

BACKGROUND/AIMS: The presenting symptom of eosinophilic esophagitis, a chronic T(H)2-type inflammatory disease, is uniform dysphagia attacks. Histology reveals a dense mucosal infiltration with eosinophils. Unfortunately, endoscopic findings are often unremarkable or misleading. This study characterizes the endoscopic manifestations of eosinophilic esophagitis and analyzes the nature and clinical features of the frequently observed white alterations. METHODS: Thirty adult patients (22 males, 8 females; mean age 40.6 years) with previously confirmed EE prospectively underwent a structured interview, physical examination, laboratory tests and upper endoscopy with histomorphometric examination of the esophageal mucosa. RESULTS: On endoscopy, all patients showed mucosal abnormalities in the esophagus. Findings included an unspectacular loss of vascular pattern (93.3%) and white exudates (53.3%). Biopsies demonstrated significantly increased eosinophilia in the white exudates (108.4 vs. 14.0 cells/hpf). A significant correlation was found between white exudates and dysphagia frequency (<1 attack/week = 20%; >1 attack/week = 70%). CONCLUSION: Eosinophilic esophagitis evokes at least 12 different signs resulting in an individually unique endoscopic pattern, but no disease-specific picture. White exudates correspond to foci of dense eosinophilic infiltration reflecting inflammatory activity and are associated with significantly more frequent dysphagia attacks. Both the lack of a typical endoscopic picture as well as the heterogeneity of the eosinophilic infiltration impede diagnosis.

Natural history of primary eosinophilic esophagitis: a follow-up of 30 adult patients for up to 11.5 years.

BACKGROUND & AIMS: Primary eosinophilic esophagitis is a chronic, increasingly recognized, interleukin 5-driven inflammatory disorder of the esophagus. The leading symptom in adults is uniform attacks of dysphagia, and the established histologic sign is a dense eosinophilic infiltration of the esophageal epithelium. Before this study, the natural course of eosinophilic esophagitis had not been defined and information regarding potential long-term risks was lacking. METHODS: This prospective case series included 30 adult patients with eosinophilic esophagitis (22 men and 8 women; mean age, 40.6 years) whose diagnosis had been made >1 year before study debut based on typical history, consistent endoscopic abnormalities, and infiltration of the esophageal epithelium with >24 eosinophils/high-power field. After a mean of 7.2 years, patients underwent a comprehensive follow-up examination. RESULTS: All patients survived the study period in good health and stable nutritional state. Dysphagia persisted in 29 patients, exerting a major negative effect on socioprofessional activities on 1 patient and a minor impact on 15. Attacks of dysphagia were more frequent in patients with blood eosinophilia or pronounced endoscopic alterations. The esophageal eosinophilic infiltration persisted in all symptomatic patients, but cell numbers spontaneously decreased significantly (78.7 vs. 40.3 cells/high-power field). The inflammatory process evoked fibrosis of the esophageal lamina propria but did not spread to the stomach or duodenum. No case evolved to a hypereosinophilic syndrome. CONCLUSIONS: Eosinophilic esophagitis, a primary and chronic disease restricted to the esophagus, leads to persistent dysphagia and structural esophageal alterations but does not impact the nutritional state. To date, no malignant potential has been associated with this disease.
