RESUMO
OBJECTIVES: To assess the impact of HIV-related immunodeficiency and antiretroviral treatment on the occurrence and evolution of abnormal Papanicolaou tests. STUDY DESIGN: Cohort of 485 HIV-infected women with a known date of infection, enrolled during May 1993-April 1998 in 23 centres (gynaecology, infectious disease or STD clinics, or drug treatment centres) in 12 European countries; in 21 centres, follow-up was performed every 6 months (median follow-up: 2 years). METHODS: Human papillomavirus (HPV) was detected at inclusion by Southern blot and PCR. The prevalence of squamous intraepithelial lesions (SIL), the incidence of SIL and regression from low-grade SIL were studied according to CD4 count after controlling for HPV detection results. RESULTS: Compared with women with CD4 cell counts > 500 x 10(6)/l, women with CD4 cell counts < 200 x 10(6)/l had a twofold increase in both prevalence and incidence of SIL and in non-regression from untreated low-grade SIL; in addition, these women had a lower response rate to treatment of high-grade cervical intraepithelial neoplasia. The increase in SIL incidence associated with a low CD4 cell count was significant in women not receiving antiretroviral treatment (relative risk, CD4 cell count 200-499 x 10(6)/l, 1.9; CD4 cell count < 200 x 10(6)/l, 2.9; CD4 cell count > 500 x 10(6)/l, reference), whereas it was less marked and not statistically significant in treated women. CONCLUSIONS: Severe HIV-related immunodeficiency strongly increases the risk of occurrence of SIL; antiretroviral treatment may reduce this risk, probably by restoring or at least preserving immune function.

BACKGROUND: Guar gum is a gel-forming fiber, which increases fecal elimination of bile acids. It may therefore be beneficial in the treatment of intrahepatic cholestasis of pregnancy. METHODS: Forty-eight patients with intrahepatic cholestasis of pregnancy were randomized double-blind to receive either guar gum or placebo until delivery. Serum bile acid concentration was measured. Pruritus was assessed by both the investigator and the patient. RESULTS: At baseline, the intensity of pruritus and the serum bile acid concentration were significantly related. Guar gum diminished or prevented worsening of pruritus, while in the placebo group pruritus was enhanced (p<0.05). In the placebo group serum bile acid concentration increased significantly, whereas in the guar gum group it remained unchanged (p<0.05 between the groups). Guar gum treatment-induced changes of the pruritus score and serum bile acid concentrations were significantly related (p<0.01). CONCLUSIONS: Guar gum relieved the intensity of pruritus without any side effects and prevented the rise in serum bile acid concentration in this placebo-controlled and double-blind study of patients with intrahepatic cholestasis of pregnancy.

BACKGROUND: Our aim was to investigate whether intestinal binding of bile acids by guar gum, a dietary fibre, relieves cholestasis and pruritus in intrahepatic cholestasis of pregnancy. METHODS: Forty-eight pregnant women with cholestasis and pruritus were randomized double-blind to guar gum and placebo until the time of delivery, and 20 healthy pregnant women were used as control subjects. The pruritus score and serum bile acids, lipids and non-cholesterol sterols were measured at baseline, at least 2 weeks after treatment, just before delivery and up to 4 weeks after delivery. RESULTS: The increase in serum bile acids and worsening of pruritus were prevented by guar gum in relation to placebo (P < 0.05). Serum cholesterol was unchanged, but increased cholesterol precursor sterol values suggested that cholesterol synthesis was increased by guar gum. Serum cholestanol proportion, an indicator of cholestasis, was related to pruritus but was unaffected by guar gum. CONCLUSION: We conclude that in intrahepatic cholestasis of pregnancy and pruritus, guar gum treatment is beneficial in relieving pruritus, even although indicators of cholestasis are only partially reduced.

BACKGROUND: The aim of the study was to analyze the reasons for the failure of contraception and the reasons for not using any contraception among women seeking a legal abortion on social grounds. The women were also asked about their knowledge of contraception methods, including postcoital contraception. METHODS: We interviewed 200 women applying for a legal abortion within the first trimester of pregnancy about contraception, the contraceptive methods used, and the possible reasons for failure of contraception. RESULTS: Of all the women interviewed, 93% claimed to have adequate knowledge of contraception. At the time of conception 11.5% used safe methods (OCs 8%, IUDs 3.5%), 63% used less safe methods, and 26% were without contraception. Only 25% of the pill users had no explanation for the failure. 76.7% of the condom users reported that the condom was broken, had slipped off or its use had been irregular. The concern about side effects was the most common reason for not using safe contraceptives (25%). CONCLUSIONS: The women claimed to have enough information about contraceptives, and postcoital contraception was also familiar, but the knowledge on how to use them in practice was inadequate. Irregular use and breaks in contraception were common. Despite the data based on Pearl indices, pills failed twice as often as IUDs. Counseling about the proper use of contraceptives is important, although the concern about the side effects appeared to be a big, unsolved problem.
PIP: Interviews with 200 abortion seekers at a Finnish hospital revealed a high incidence of contraceptive failure. Although 93% claimed to have adequate knowledge about contraception, only 23 women (11.5%) were using a reliable method (pill or IUD) at the time of conception. 126 (63%) were relying on a less safe method (e.g., condoms, spermicides, rhythm) and 51 (25.5%) were not using any form of fertility control. 9 of the 16 pill users admitted irregular use; another 3 experienced vomiting or diarrhea at the time of conception, which may have compromised the method's effectiveness. Of the 116 condom users, 89 reported that the condom had broken or slipped off during intercourse or that use had been irregular. Concern about side effects was the most frequently cited reason for not using the pill or IUD; in many other cases, women had been advised by their physician to take a break from use of these methods. Overall, contraceptive failure was considered to have occurred in 43 cases (21.5%); the methods involved were IUD (7 cases), pill (4 cases), condoms (27 cases), and spermicides (5 cases). Recommended to reduce the high rate of contraceptive failure are counseling on proper method use and the alleviation of concern about side effects associated with the most effective methods.
