Abstract
BACKGROUND Lyme disease (LD), the most common vector-borne disease in the United States, typically presents with a localised erythema migrans rash (EM). Left untreated, infection can disseminate to cause severe heart, joint or nervous system manifestations. Summaries of LD surveillance data have been published previously but did not include the frequency, demographic or clinical characteristics of LD cases during pregnancy. METHODS We summarised confirmed and probable LD cases by pregnancy status as reported to the U.S. Centers for Disease Control and Prevention during 1992-2019. We defined an LD case during pregnancy as one with (1) female sex, (2) age 14-49 years and (3) positive pregnancy indication. We evaluated the frequency, seasonality, age distribution, race and ethnicity, geographic distribution and clinical manifestations of LD cases during pregnancy and cases among non-pregnant females. We compared proportions using chi-squared tests. RESULTS Among 698,876 reported LD cases, 112,002 (16%) were confirmed or probable cases among females aged 14-49 years; 32,301 (29%) were specifically reported as non-pregnant and 643 (0.6%) (568 confirmed and 75 probable cases) reported as pregnant. Illness onset peaked in June among LD cases during pregnancy, but in July for cases among non-pregnant females. A higher proportion of confirmed LD cases during pregnancy had only EM rash than did cases among non-pregnant females (66% vs. 60%, p = 0.019). CONCLUSIONS LD cases during pregnancy are rare. Compared to non-pregnant females, cases among pregnant females more commonly involve early clinical manifestations. These patterns could suggest earlier detection or more complete reporting of LD cases during pregnancy than their non-pregnant counterparts. Earlier detection could be due to frequent contact with healthcare or increased self-advocacy during pregnancy. Prompt antimicrobial treatment is critical for preventing severe disease and reducing risk of adverse pregnancy or birth outcomes.

Abstract
INTRODUCTION Studies investigating the relationship between sex hormones, inflammatory mediators and joint disorders have reported that sex hormones affect the pathogenesis of joint disorders. We aimed to investigate temporomandibular joint disorder (TJD) in polycystic ovary syndrome (PCOS) and the possible role of systemic mediators and sex hormones in TJD pathogenesis. MATERIAL AND METHODS PCOS patients (n = 45) and controls (n = 30) aged 20-40 years, were enrolled in this case-control study. TJD diagnosis was performed by the specialist and blood samples were tested in the early follicular phase and on the 21 st (midluteal) day to investigate the levels of estrogen, progesterone, matrix metalloproteinase (MMP) 1-8-9, interleukin (IL)-1ß and Tumor necrosis factor (TNF)-α. RESULTS TJD incidence was significantly higher in PCOS than the control group (51.1% and 6.9% respectively, p < 0.01). Midluteal progesterone (p < 0.01) was lower in PCOS group than the controls (p < 0.01). TNF-α (p < 0.01), MMP 1 (p < 0.01) and MMP 8 (p = 0.02) levels were found significantly higher in PCOS than the control group. Further, Progesterone levels were found significantly lower in TJD (+) PCOS patients than TJD (-) PCOS patients. However, significant difference was not found between the PCOS TJD (+) and PCOS TJD (-) patients for estrogen, MMP 1, MMP 8, MMP 9, TNF-α and IL-1ß. CONCLUSIONS TJD frequency was found significantly increased in PCOS patients. Related with this, TJD co-occurrence should be kept in mind in the diagnosing and treatment process of PCOS due to hormonal alteration.

Abstract
Information on Lyme borreliosis (LB) during pregnancy is limited. In the present study, the course and outcome of erythema migrans (EM) in 304 pregnant women, diagnosed in the period 1990–2015, was assessed and compared with that in age-matched non-pregnant women. The frequency of unfavorable outcome of pregnancies was also evaluated. The pregnant women reported constitutional symptoms less frequently than the non-pregnant women (22.4% vs. 37.2%, p < 0.001). Pregnant women diagnosed with EM later during pregnancy had a lower probability of reporting constitutional symptoms (odds ratio = 0.97 for 1-week difference in gestation week at diagnosis of EM, 95% CI: 0.94–0.99, p = 0.02). The outcome of pregnancy was unfavorable in 42/304 (13.8%) patients: preterm birth in 22/42 (52.4%), fetal/perinatal death in 10/42 (23.8%), and/or anomalies in 15/42 (35.7%). Several patients had potential explanation(s) for the unfavorable outcome. In conclusion, the course of early LB during pregnancy is milder than in age-matched non-pregnant women. The outcome of pregnancy with the treatment approach used in the present study (i.v. ceftriaxone 2 g once daily for 14 days) is favorable.

Abstract
Sex hormones may contribute to the symptomatology of female-predominant temporomandibular disorders (TMDs) inflammatory pain. Pregnant women show less symptoms of TMDs than that of non-pregnant women. Whether progesterone (P4), one of the dominant sex hormones that regulates multiple biological functions, is involved in symptoms of TMDs remains to be explored. Freund’s complete adjuvant were used to induce joint inflammation. We evaluated the behavior-related and histologic effects of P4 and the expression of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in the synovial membrane. Primary TMJ synoviocytes were treated with TNF-α or IL-1β with the combination of P4. Progesterone receptor antagonist RU-486 were further applied. We found that P4 replacement attenuated TMJ inflammation and the nociceptive responses in a dose-dependent manner in the ovariectomized rats. Correspondingly, P4 diminished the DNA-binding activity of NF-κB and the transcription of its target genes in a dose-dependent manner in the synovial membrane of TMJ. Furthermore, P4 treatment showed decreased mRNA expression of proinflammatory cytokines, and partially reversed TNF-α and IL-1β induced transcription of proinflammatory cytokines in the primary synoviocytes. Moreover, progesterone receptor antagonist RU-486 partially reversed the effects of P4 on NF-κB pathway. In conclusion, progesterone ameliorated TMJ inflammation through inhibition of NF-κB pathway.

Abstract
A wide array of infectious diseases can occur in pregnancy. Their acquisition, clinical presentation, and course during gestation may be altered due to an impairment of the maternal cellular immunity. Some infectious diseases can lead to serious consequences for the mother or the offspring, including congenital malformations. This review describes in detail the clinical presentation, course, management, and associated maternal and fetal risks of selected viral (varicella-zoster virus infections, condylomata acuminata), fungal (candida vulvovaginitis), bacterial (Lyme borreliosis), and parasitic (scabies) infections. The treatment options are critically reviewed. First-line therapies include acyclovir and varicella-zoster virus immunoglobulin for varicella-zoster virus infections, surgical modalities for genital warts, topical clotrimazole and oral fluconazole for Candida vulvovaginitis, amoxicillin and cefuroxime for Lyme borreliosis, and permethrin for scabies. A synopsis of maternal and fetal risks of other important infections is also included.

Abstract
Progesterone has been demonstrated to be involved in maintaining pregnancy by regulating immunocytes. Dendritic cells (DCs), the most potent triggers of the adaptive immune response, express receptors for steroid hormones and are regarded as one of the primary targets of progesterone. However, the functional modification of DCs by progesterone remains poorly understood. Here, we report that progesterone does not affect the morphology or apoptosis of murine bone marrow-derived DCs. Progesterone-treated DCs were characterized by decreased expression of Ia (MHC class II), CD80 and CD86, increased production of IL-10, and decreased secretion of IL-12. Compared with mature DCs (mDCs), activated progesterone-treated DCs had a reduced capacity to stimulate CD4(+) T cell proliferation. The observation that progesterone-treated DCs could attenuate delayed-type hypersensitivity (DTH) responses in vivo suggests that progesterone mediates suppressive DC activity. However, transfer of progesterone-treated DCs into the peritoneal cavity of mice did not elevate the percentage of CD4(+)CD25(+)Foxp3(+) regulatory T cells in the spleen. Overall, our study helps to increase understanding of the role of DCs exposed to progesterone in the maintenance of pregnancy.

Abstract
Sexual dimorphism in human immune systems is most apparent in the female predominance of certain autoimmune diseases (ADs) like systemic lupus erythematosus (SLE). Epidemiologic, observational and experimental evidence strongly suggest sex steroids are important modulators of genetic risk in human AD. In this regard, the roles of progesterone (Pg), an immunomodulatory female sex steroid, are poorly understood. Several lines of investigation indicate Pg and synthetic progestins impact risk of AD and immune-mediated injury in different ways depending on their concentrations and their engagement of various Pg receptors expressed in immune organs, immune cells or tissues targeted by immune attack. At low physiologic levels, Pg may enhance interferon-alpha (IFN-α) pathways important in SLE pathogenesis. Commonly used synthetic progestins may have the opposite effect. At pregnancy levels, Pg may suppress disease activity in rheumatoid arthritis (RA) and multiple sclerosis (MS) via inhibition of T helper type 1 (Th1) and Th17 pathways and induction of anti-inflammatory molecules. Importantly, Pg's immunomodulatory effects differ from those of estrogens and androgens. An additional layer of complexity arises from apparent interdependence of sex hormone signaling pathways. Identifying mechanisms by which Pg and other sex steroids modulate risk of AD and immune-mediated injury will require clarification of their cellular and molecular targets in vivo. These future studies should be informed by recent genetic discoveries in human AD, particularly those revealing their sex-specific genetic associations.

Abstract
The article outlines examples of a viral (varicella-zoster virus, VZV), a bacterial (Lyme borreliosis) and a parasitic (scabies) infection in pregnancy with their risk for the mother and/or child as well as their management. VZV infections cause various clinical scenarios depending on the maternal immune status and the time of infection. Herpes zoster usually poses no risk to the pregnant woman and there is no need for antiviral therapy. VZV infection of a seronegative mother, however, may lead to severe varicella in the pregnant woman and to congenital malformations (congenital varicella syndrome) in case of early infection or neonatal varicella in case of perinatal infection. Prompt therapy with acyclovir or administration of VZV immunoglobulin for prophylaxis is mandatory in those patients. In case of Lyme borreliosis of the mother, adequate antibiotic therapy with amoxicillin prevents harm to the fetus. Doxycycline is contraindicated during pregnancy. Scabies represents an important differential diagnosis of pruritic dermatoses in pregnancy and should be treated with permethrin 5% cream.

Abstract
Dendritic cells (DCs) are critical mediators of adaptive immunity, tolerance and autoimmunity. The human immune system exhibits sexual dimorphism, which is most evident in the female predominance of autoimmune diseases such as systemic lupus erythematosus (SLE). Female sex steroids are strongly implicated in mediating immune sexual dimorphism, in part because estrogen accentuates disease in several models of lupus autoimmunity. In contrast, progesterone may prevent disease development. While much investigation has focused on the effects of estrogen and progesterone on lymphocyte functions, far less attention has been paid to the effects of these hormones on DCs. Current evidence now indicates estrogen can activate DCs, while in contrast, progesterone inhibits DC functions. Thus, we hypothesize that the opposite effects these two hormones have on lupus autoimmunity reflect opposing effects on DC functions. Thus, through direct actions on DCs, female sex steroids may influence autoimmunity, immunity and tolerance.

Abstract
Immune balance controlled by Th1 and Th2 cells is critical for the protection of host from pathogenic invasion while its imbalance becomes the cause of various immune disorders including autoimmune diseases. Cytokines, such as IL-12 and IL-4, are critical factor to drive the differentiation of naïve CD4(+) T cells to Th1 or Th2 cells. In addition to cytokines, steroid hormones have been demonstrated to affect on the control of Th1/Th2 balance and the onset of autoimmune diseases. Here, we will propose a new concept that immunosteroid, which is designated as a steroid produced by immunoregulatory cells, also play a critical role for regulation of Th1/Th2 balance. First example of immunosteroid is Th2-dependently produced progesterone. Th2 cells, but not Th1 cells expressed P450scc and 20alpha-HSD and produced progesterone from 22R-hydroxycholesterol in cooperation with 3beta-HSD-expressing mouse fibroblasts. Th2-dependently produced progesterone induced apoptotic cell death of Th1 cells and inhibited the differentiation of Th1 cells. While Th2 cells were escaped from toxic effect of progesterone by metabolizing it to non-toxic 20alpha-hydroxyprogesterone with 20alpha-HSD. Second example of immunosteroid is dendritic cell (DC)-dependently produced 1alpha,25-dihydroxyvitamin D3 [1,25(OH)(2)D] secosteroid hormone, which has been demonstrated to inhibit autoimmune diseases. We found that 25-hydroxyvitamin D3 1alpha-hydroxylase, which metabolize 25-hydroxyvitamin D3 (inactive form) to 1,25(OH)(2)D was expressed in Th2-cytokine induced bone marrow-derived DC2 but not Th1-cytokine induced DC1. Moreover, 1,25(OH)(2)D was significantly inhibited DC1-induced type1 immunity. Thus, we initially demonstrated the critical role of immunosteroids in the control of Th1/Th2 balance influencing on the onset of autoimmune diseases. Therefore, it will be an important issue to investigate the possible role of immunosteroids for the regulation of autoimmune diseases.

Abstract
To clarify the role of progesterone in the development of immune responses during pregnancy against Neospora caninum infection, C57BL/6 mice were given a progesterone pellet, and measured on Interferon-gamma and interleukin-4 production following the infection. IFN-gamma production in the prescribed group was significantly lower than that in the intact group on day 40 post administration. IL-4 producing cell population in the prescribed group was larger than that in the intact group. These results suggest that progesterone may alter the balance of cytokine production, and that the bias toward type 2 immune response may remain for a certain period after the infection.

Abstract
Lyme borreliosis is a complex infection, where some individuals develop so-called 'chronic borreliosis'. The pathogenetic mechanisms are unknown, but the type of immune response is probably important for healing. A strong T helper cell type 1 (Th1)-like response has been suggested as crucial for eradication of Borrelia and for avoiding development of chronic disease. Many studies aimed at altering the Th1/Th2 balance in Lyme arthritis employed mice deficient in cytokine genes, but the outcome has not been clear-cut, due possibly to the high redundancy of cytokines. This study aimed at studying the importance of the Th1/Th2 balance in murine Borrelia arthritis by using the Th2-deviating effect of subtoxic doses of inorganic mercury. Ninety-eight C3H/HeN mice were divided into four groups: Borrelia-infected (Bb), Borrelia-infected exposed to HgCl(2) (BbHg), controls exposed to HgCl(2) alone and normal controls. Mice were killed on days 3, 16, 44 and 65 post-Borrelia inoculation. Arthritis severity was evaluated by histology, spirochaetal load determined by Borrelia culture, IgG2a- and IgE-levels analysed by enzyme-linked immunosorbemt assay (ELISA) and cytokine-secreting cells detected by enzyme-linked immunospot (ELISPOT). BbHg mice showed less severe histological arthritis, but delayed eradication of spirochaetes compared to Bb mice, associated with increased levels of IgE (Th2-induced) and decreased levels of IgG2a (Th1-induced), consistent with a Th2-deviation. Both the numbers of Th1 and Th2 cytokine-secreting cells were reduced in BbHg mice, possibly explained by the fact that numbers of cytokine-secreting cells do not correlate with cytokine concentration. In conclusion, this study supports the hypothesis that a Th1-like response is required for optimal eradication of Borrelia.

Abstract
Many epidemiological studies suggest that women are at increased risk of developing adult-onset asthma and also suffer from more severe disease than men. These gender differences appear to be the product of biological sex differences as well as sociocultural and environmental differences. The biological sex differences include genetic, pulmonary, and immunological factors. There is compelling evidence that sex hormones are major determinants of at least these biological sex differences. This paper explores the current literature regarding effects of sex hormones on immune function, resident lung cells, and regulation of local processes in the lung to shed light on underlying mechanisms of gender differences in asthma. More research is needed to understand these mechanisms in order to improve treatment of women with asthma.

Abstract
UNLABELLED Lyme disease is the most common vector-borne disease in the United States. A number of other spirochetal diseases, if contracted in pregnancy, have been shown to cause fetal harm and there is concern over a similar effect with gestational borreliosis. Previously published individual case reports have suggested a possible association between gestational borreliosis and adverse pregnancy outcome; however, no specific pattern of teratogenicity has been shown, and a causal relationship has never been proven. In addition, larger epidemiological and serological series have consistently failed to demonstrate an increased risk to pregnant women who develop Lyme disease if they receive appropriate antimicrobial therapy. We describe a favorable outcome in a 42-year-old woman who developed Lyme disease in the third trimester and was treated with a full course of oral amoxicillin. In addition, we offer a review of the relevant literature regarding Lyme disease and pregnancy. The appropriate investigation and management of a woman with gestational borreliosis are discussed. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to recall that Lyme disease is not an uncommon disease during pregnancy and can occur in states outside of the Northeast, explain that the diagnosis is made clinically and may be confirmed by laboratory tests, state that treatment is recommended during pregnancy, and summarize that there is no consistent data of adverse fetal effects even though the placenta is infected.

Tibolone and metabolites induce prolactin production in human endometrial stromal cells in vitro: evidence for cell-specific metabolism. J Steroid Biochem Mol Biol 2006; 100:152-60.

Abstract
In this study, we assessed the effects of tibolone and its metabolites on the production of a progesterone sensitive parameter, prolactin, in human endometrium stroma cells in vitro. In addition, the metabolism of the compounds by isolated stromal and epithelial cells was evaluated. The reference compounds, progesterone, Org 2058, and DHT all induced prolactin production. Oestradiol also slightly induced prolactin production and enhanced the response to Org 2058. Tibolone and Delta4-tibolone were similar with regard to potency to induce prolactin levels in the culture supernatant. Their potency was lower than that of Org 2058, similar to that of progesterone and higher than that of DHT. The efficacies of tibolone, Delta4-tibolone and Org 2058 were similar (approximately 200-fold induction). The estrogenic tibolone metabolites 3alpha- and 3beta-OH tibolone also significantly stimulated prolactin production. Their potency, however, was low since significance was reached only at the highest concentrations tested. The PR antagonist Org 31710 inhibited both tibolone- and Delta4-tibolone-induced prolactin production. The responses of tibolone and Delta4-tibolone were not affected by co-incubation with the androgen receptor antagonist OH-flutamide. The effect of tibolone, but not Delta4-tibolone, was antagonized approximately 50% in combination with the highest dose (1 microM) estrogen receptor antagonist, ICI 164384. The induction of prolactin by 3alpha- and 3beta-OH tibolone was antagonized most potently by Org 31710, but also by ICI 164384 and OH-flutamide. Tibolone is metabolized differently in epithelial and stromal cells of the human endometrium. The epithelial cells mostly produce the progestagenic/androgenic Delta4-tibolone. The stromal cells produce predominantly the 3beta-OH tibolone, and some Delta4-tibolone, but the net effect observed with regard to prolactin production is progestagenic. When the metabolites 3alpha-OH, 3beta-OH, and Delta4-tibolone were added to the cultures no conversions were observed. The HPLC analyses showed no evidence for the production of sulfated metabolites. In conclusion, the net effects on endometrial stromal cells are predominantly progestagenic. Tibolone is converted by epithelial cells into Delta4-tibolone which displays progestagenic and androgenic activities, whereas in stromal cells also the estrogenic metabolites 3alpha- and 3beta-OH tibolone are formed.

Orsal AS, Blois S, Labuz D, Peters EMJ, Schaefer M, Arck PC. The progesterone derivative dydrogesterone down-regulates neurokinin 1 receptor expression on lymphocytes, induces a Th2 skew and exerts hypoalgesic effects in mice. J Mol Med (Berl) 2005; 84:159-67. [PMID: 16389545 DOI: 10.1007/s00109-005-0005-5] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2005] [Accepted: 09/13/2005] [Indexed: 10/25/2022]
Abstract
Accumulating evidence indicates that the neuropeptide substance P (SP) is predominantly involved in neurogenic inflammation and pain perception via its high-affinity neurokinin 1 receptor (NK-1R). Intriguingly, decreased pain sensitivity is found to be associated with high plasma progesterone levels. We hypothesize that progesterone may attenuate nociception and associated inflammatory response via NK-1R-dependent pathways. To address our hypothesis, we incubated splenic lymphocytes from CBA/J female mice with different concentrations of the progesterone derivative dydrogesterone. Subsequently, the expressions of NK-1R and T helper (Th1)-type cytokines were analyzed by flow cytometry. Next, we subcutaneously injected CBA/J mice with 1.25 mg of dydrogesterone in 200-microl sesame oil; control mice were sham-injected. Tail flick test to detect the nociceptive threshold was performed in 30-min intervals upon injection. Lymphocytes were isolated from blood and uterus and analyzed for NK-1R surface expression. Immunohistochemical analyses were performed to investigate the uterine tissue distribution of NK-1R. Dydrogesterone induced a decrease in the percentage of NK-1R+ lymphocytes in vitro and in vivo. Additionally, an increase in Th2-type and a decrease in Th1-type cytokines could be detected in vitro after incubation with dydrogesterone. An increased tail flick latency following dydrogesterone injection supported the concept that decreased expression of the NK-1R on lymphocytes is associated with an increased pain threshold. Taken together, these results clearly reveal a pathway by which dydrogesterone or progesterone respectively modulates the cross talk of the nervous, endocrine and immune systems in inflammation and pain.

Abstract
In the United States, intermittent or chronic mono- or oligoarthritis, particularly affecting the knee, is the most common manifestation of late Lyme disease (LD). Lyme arthritis (LA) can usually be prevented by early treatment of acute LD. However, the erythema migrans rash may go undetected in children and in the dark skin of African Americans, leading to delayed treatment and a relatively increased incidence in LA. Virtually all untreated patients with LA have high levels of serum immunoglobulin G antibodies, and sometimes low levels of immunoglobulin M antibodies, to Borrelia burgdorferi (Bb) by ELISA and Western blot. These responses may persist for many years after antibiotic treatment, and therefore, serologic results do not accurately distinguish between active or past infection. Most patients with LA respond well to standard courses of antibiotic treatment, but a small percentage have persistent knee synovitis, in some cases possibly related to the triggering of intrasynovial autoimmunity. Other patients develop a syndrome of diffuse arthralgia, myalgia, fatigue, and subjective cognitive difficulty during or soon after LD, which persists despite antibiotic treatment. Patients with this post-treatment, post-LD syndrome were recently studied in a placebo-controlled double-blind antibiotic trial. There was no evidence of Borrelial infection in these patients by culture or detection of Bb DNA in blood or spinal fluid. Furthermore, there was no difference in responsiveness of these patients to a 3-month course of antibiotic compared with placebo treatment. Thus, LA caused by active Bb infection, post-treatment LA with persistent knee synovitis and post-LD syndrome are distinct and distinguishable clinical entities.
