A wide variety of topics are addressed in this chapter, including fertility, gonadal failure, erectile dysfunction, and menstrual issues in SCD. Etiologies of impaired male fertility are multifactorial and include hypogonadism, erectile dysfunction, sperm abnormalities, and complica- tions of medical therapies. Much less is known about the prevalence and etiology of infertility in women with SCD. Other reproductive issues in women included in this review are pain and the menstrual cycle, contraception, and preconception counseling. Finally, long-term therapies for SCD and their impact on fertility are presented. Transfu- sional iron overload and gonadal failure are addressed, followed by options for fertility preservation after stem cell transplantation. Focus is placed on hydroxyurea therapy given its beneﬁts and increasing use in SCD. The impact of this agent on spermatogenesis, azoospermia, and the developing fetus is discussed.

Two published trials comparing esomeprazole 40 mg with omeprazole 20 mg found a 5, 12 36, 38 statistically significantly higher healing rate in the esomeprazole group. Two others found no difference between groups at 4 and 8 weeks. A small study (N=48) not included in Table 5 found a higher healing rate for esomeprazole at 8 weeks (64% compared with 46%), but the 31 difference was not statistically significant. The study may not have had sufficient power to detect a difference between treatment groups; no power calculation was reported. The pooled risk difference for 4 studies at 4 weeks was 7% and for 5 studies at 8 weeks was 5%, favoring esomeprazole (see Table 6). This translates to a number needed to treat with esomeprazole to heal 1 additional patient at 4 weeks of 14, and a number needed to treat at 8 weeks of 20. In a large, 4 good-quality trial in 5241 patients at multiple centers in the United States, healing rates were 18 higher in the esomeprazole group at 4 and 8 weeks. A smaller, fair-quality trial in patients with mostly mild to moderate esophagitis found the drugs to have equivalent healing rates at 8 weeks; 29 results at 4 weeks were also similar between drugs. The third study, rated good quality, was conducted in patients with moderate to severe esophagitis. At 4 weeks, the esomeprazole group had a higher healing rate, but at 8 weeks the difference was not significant. Pooled estimates show that with esomeprazole, healing rate is higher by 5% at 4 weeks and by 3% at 8 weeks (Table 6). With a random-effects analysis the difference at 8 weeks is not significant, but in fixed-effects analysis, the difference is significant (see table 6). The fixed- effect estimates of risk difference correspond to a number of patients needed to treat with esomeprazole instead of lansoprazole to heal 1 additional patient at 4 weeks equal to 20 and at 8 weeks equal to 33.

Two 30 studies find esomeprazole superior, while 2 do not. One large study (N=3171) found that healing at 4 weeks was 6% higher in the esomeprazole group (95% CI 3 to 9). At 8 weeks, the difference was smaller but statistically significant (risk difference, 3%; 95% CI 1 to 5). A much smaller study (N=180) was also rated fair to poor because numbers of patients enrolled and analyzed in tables did not match the numbers discussed in the text (apparently a typographical error was made in Table 1), the study was apparently open-label, 37 and no details on randomization or allocation concealment procedures were given. This study also found esomeprazole 40 mg to have significantly higher rates of healing at 4 weeks (78% compared with 72%; P<0. Rates at 8 weeks were not statistically significantly different (92% compared with 91%). No patients with Grade D esophagitis were enrolled in this study, although they were not excluded 20, Two studies (N=227 and 581) found no differences in healing rates between the drugs 33 at early time points (4 to 6 weeks in 1 study, 4 weeks in the other) or later time points (8 to 10 weeks in 1 study, 8 and 12 weeks in the other). The smaller of these studies included only 20 patients with Grade B or C esophagitis. The 2 largest of these studies also examined the impact of Helicobacter pylori status on healing rates with the 2 drugs. One found that healing rates with esomeprazole were not different based on Helicobacter pylori status, but that Helicobacter pylori negative patients had lower 30 healing rates with pantoprazole compared to those who were Helicobacter pylori positive. The other study, however did not find any associated differences in healing rate, symptom relief or 33 ‘complete remission’ when using intention to treat analyses. However, data on the crude rates of healing were provided by AstraZeneca through public comment on this report; the data used in the analysis below for this study are not published data. Using these data to conduct a pooled analysis of the 3 studies that included patients with all grades of esophagitis indicates that esomeprazole 40 mg is superior to pantoprazole 40 mg in rates of patients with healed erosions at 4 weeks, but not at 8 weeks (Table 8 below).
