RESUMO
The factors predicting an unfavourable response of genital warts to treatment have not been determined. The disease characteristics were recorded for 390 patients with genital warts and treated by cryotherapy. The time to achieve clearance was recorded. A personal and family history of asthma, hay fever or eczema, as well as a personal history of common warts and number of recurrences was obtained by telephone four to five years after the clinical visits. In multiple regression analysis, the number of lesions (P < 0.001), extent of the disease (P = 0.003) and personal history of atopy (P = 0.001) were found to influence the time until response to treatment. Similar results were obtained for family history of atopy. The number of sexual partners (P = 0.007), extent of the disease (P = 0.009) and personal history of atopy (P < 0.001) were the main factors influencing the probability of recurrence in multiple logistic regression. The results for family history of atopy were again similar. The study concludes that atopy is a major factor influencing the time frame of the therapeutic response and the probability of recurrence in patients with genital warts.

BACKGROUND: Increases in plasma concentrations of lipids, triglycerides, and liver enzymes have been reported in patients on isotretinoin therapy. Lipoprotein (a). (Lp (a)), a cholesterol-rich plasma lipoprotein, influences the clotting system and is related to premature coronary heart disease and stroke. METHODS: Blood (7 mL) was obtained from 30 patients with cystic acne before and 30 days after the initiation of oral isotretinoin (0.5 mg/kg/day). RESULTS: An increase in liver enzymes and lipids, except high density lipoprotein, was found in our patients at the end of the study. The mean Lp (a) levels (initial value, 25.91 +/- 3.17 mg/dL) were statistically reduced (p < 0.0001) at the end of treatment (14.80 +/- 2.35 mg/dL). CONCLUSIONS: It is suggested that isotretinoin could be used as an Lp (a) lowering agent in the future.

The type 1 and type 2 glycoprotein G (gG1 and gG2) of herpes simplex virus (HSV) were expressed in Escherichia coli as fusion proteins with the maltose binding protein (MBP) using the pMAL-c2 expression vector. The MBP-gG1 fusion protein contains all but the four amino acids from the amino-terminus of gG1, whereas the MBP-gG2 fusion protein was missing the first 30 amino acids that comprise the signal peptide of the protein. The diagnostic value of these antigens was examined by two methods: (1) immunoblot assay based on MBP-gG1 and MBP-gG2 fusion proteins present in crude E. coli cell extracts and (2) enzyme-linked immunosorbent assay (ELISA) of immunoaffinity-purified recombinant MBP-gG1 and MBP-gG2 fusion proteins. Of 28 serum samples known to have antibody to HSV-1 (10 specimens positive for HSV-1 alone and 18 specimens positive for mixed antibody to HSV-1/HSV-2), 27 were reactive to the MBP-gG1 recombinant protein both in ELISA and in immunoblotting. In addition, of 20 serum samples known to have antibody to HSV-2 (2 specimens positive for HSV-2 alone and 18 samples positive for mixed antibody to HSV-1/HSV-2), 15 were found to be reactive to the MBP-gG2 recombinant protein by ELISA and 16 by immunoblotting. None of the 13 HSV-antibody-negative serum samples showed reactivity to the MBP-gG1 or MBP-gG2 antigens by either assay. Moreover, none of the serum samples known to have antibody to HSV-1 alone showed reactivity to the MBP-gG2 recombinant antigen. This study verified the potential application of the E. coli-expressed recombinant gG1 and gG2 proteins as diagnostic antigens and demonstrated the MBP fusion system to be a simple and effective method of producing adequate amounts of low-cost, easily purified gG antigens.
