Objective: To examine the pathologic findings of eyes treated with ganciclovir implants. design: Retrospective consecutive case series. Participants: Thirty-three eyes from 19 AIds patients with ganciclovir implants. Methods: Pathologic specimens collected from 1993 through 1999 at the National Eye Institute were reviewed. Thirty-three eyes from 19 patients were identified with ganciclovir implants. The submitted eyes then were sectioned through the implant site and stained with hematoxylin and eosin, periodic acid-schiff, and other special stains when needed. Medical records, including operative and postoperative notes, were reviewed carefully. Main Outcome Measure: Light microscopic findings at and around the site of implantation. Results: scars of surgical perforation were present in all eyes. Fibrous ingrowth developed from the implant site into the vitreous in 32 of the 33 eyes. Vitreous hemorrhage was present in 18 of the 33 eyes. Poor wound apposition was found in 2 of the 33 eyes, both of which had undergone multiple procedures. Foreign body giant cell reactions were observed in most of the eyes related to suture material. Thirty-two of the 37 implant sites were located within the pars plana, whereas the other 5 were either on the border of the pars plana and pars plicata (n=4) or within the pars plicata (n=1). Hyalinization, atrophic changes of the ciliary body in the area of implantation, or both were observed in 18 eyes. Conclusions: The ganciclovir implant is well tolerated within the eye. Fibrous ingrowth is present in most eyes and seems to be a benign occurrence because of its limited extension. Microscopic vitreous hemorrhage is present in many eyes, especially those that underwent multiple procedures. Poor wound apposition occurred rarely and was found only in eyes that had undergone multiple procedures.

Aims: Anaemia is a common comorbidity in chronic heart failure(CHF). The predictors of new onset anaemia(NOA) and its long-term prognostic value, particularly in patients treated with beta-blockers, are not known. Methods and results: In COMET, 3029 patients with CHF in NYHA Ⅱ-IV and EFdomized to carvedilol or metoprolol tartrate and were followed for an average of 58 months. Plasma haemoglobin(Hb) concentrations were measured at a central laboratory at randomization, at four monthly intervals for the first year and annually thereafter. According to WHO criteria, anaemia was.d.fined when Hb measureddL for men anddL for women. We cons.d.red anaemia to be severe when HbdL for men anddL for women. The baseline mean Hb was 14.2±1.5 g/dL(n=2996) and 15.9%of patients had anaemia(males, 16.0%; females, 15.2%). At baseline, severe anaemia was found in 3.3%of patients(males, 3.6%; females, 2.0%). during the study, all-cause mortality(RR 1.47) death or hospitalization(RR 1.28), and heart failure hospitalization(RR 1.43, all Pd with non-anaemic patients. In patients without anaemia at baseline, at the end of the study, the cumulative frequency of NOA was 28.1%in males and 27.0%in females. NOA increas.d.over time from 14.2%at year 1 to 27.5%at year 5. Predictors of NOA were: higher age, diuretic dose, creatinine(all Pserum potassium, lower serum s.d.um, body mass index, and use of aldosterone antagonists, carvedilol, and digitalis(all Pdilol(vs. metoprolol tartrate) was associated with a 24%increas.d.risk to develop NOA(P=0.0047),but not severe anaemia(P=0.18). Patients with a Hb decrease of >3 g/dL(RR 3.37, PdL(RR 1.47, P=0.011) from baseline had an increas.d.subsequent mortality when compared with patients having Hb increases of 0-1.0 g/dL.

Chronic heart failure(CHF)is an increasingly common cardiovascular disorder. Many patients who have CHF report moderate to marked decreases in the frequency of sexual activity, and up to 75%of patients report erectile dysfunction(Ed). There are few controlled clinical data on the efficacy and safety of sildenafil citrate in men who have Ed and CHF; thus, we evaluated these parameters in patients who had stable CHF. This was a double-blind, placebo-controlled, flexibledose study. Men who had Ed and stable CHF were randomized to receive sildenafil or placebo for 12 weeks. Primary outcomes were questions 3 and 4 of the International Index of Erectile Function. secondary outcomes included the 5 functional domains of the International Index of Erectile Function, 2 global efficacy assessment questions, intercourse success rate, the Erectile dysfunction Inventory of Treatment satisfaction, and the Life satisfaction Checklist. By week 12, patients who received sildenafil(n=60)showed significant improvements on questions 3 and 4 comparedwith patients who received placebo(n=72; ps of patientswho received sildenafil reported improved erections(74%)and improved intercourse(68%)compared with patients who received placebo(18%and 16%, respectively). Intercourse success rates were 53%among patients who received sildenafil and 20%among those who received placebo. Patients who received sildena-fil were highly satisfied with treatment and their sexual life compared with patients who received placebo. sixty percent of patients who received sildenafil and 48%of patients who received placebo developed adverse events, including transient headache, facial flushing, respiratory tract infection, and asthenia. The incidence of events related to cardiovascular effects was low. sildenafil is an effective and well-tolerated management of Ed in men who have mild to moderate CHF.

Background-Endothelial function is known to be impaired in subjects with chronic heart failure(CHF), but the association between endothelial function and subsequent mortality risk in CHF has not been previously reported. Methods and Results-Biomarkers of endothelial function in the systemic arterial circulation(flow-mediated dilation [FMd] in the brachial artery) and the pulmonary circulation(exhaled nitric oxide [NO] production during submaximal exercise) were prospectively assess.d.in 259 subjects with New York Heart Association class II-III CHF. In subjects with FMd measurements(n=149), there were 12 deaths and 5 urgent transplantations over a median follow-up period of 841 days. In subjects with exhaled NO production measurements(n=110), there were 18 deaths and 1 urgent transplantation over a median follow-up period of 396 days. Both decreas.d.FMd and decreas.d.exhaled NO production were associated with increas.d.risk of death or urgent transplantation after adjustment for other known CHF prognostic factors(age, etiology of CHF, functional class, left ventricular ejection fraction) in Cox multivariate proportional hazards models(adjusted hazard ratio [HR] estimate for a 1%decrease in FMd=1.20; 95%confidence interval [CI], 1.03 to 1.45; P=0.027; adjusted HR estimate for a 1-ppb/min decrease in exhaledNOproduction=1.31,95%CI, 1.01 to 1.69,P=0.04)-. Conclusions-Endothelial dysfunction in CHF, as assess.d.by FMd in the brachial artery and exhaled NO production during submaximal exercise, is associated with an increas.d.mortality risk in subjects with both ischemic and nonischemic CHF.
