Gonococcal infections in newborns and in adolescents

Risk factors associated with increasing prevalence of gonorrhea and the antimicrobial susceptibility profiles of Neisseria gonorrhoeae among adolescents: A decade-long, hospital-based study from India

Background

Gonorrhea is a significant cause of morbidity among sexually active population. Young adults and adolescents have a high risk of contracting sexually transmitted infections (STIs) due to behavioral, biological, and cultural factors fuelling the epidemic among them. The Centers for Disease Control recommends annual STI screening for sexually active individuals under twenty-five and those at higher risk. The present study aims at determining the risk factors linked to the rising prevalence of gonorrhea among Indian adolescents and antimicrobial susceptibility profiles of Neisseria gonorrhoeae.

Materials and Methods

Clinical samples from adolescents attending the STI clinics were collected over 10 years. The isolates were confirmed as N. gonorrhoeae and antimicrobial susceptibility tests were performed to various drugs using the minimum inhibitory concentration strip method.

Results

A total of 7308 genital discharge specimens were collected from STI clinic attendees, of which 417 samples were positive for gonorrhea (25 among male adolescents). Seventy six percent of positive adolescents had multiple sex partners, with only 4% using condoms. Nearly 20% practiced exchange of drugs for sex. Antimicrobial susceptibility rates were 96% sensitive for azithromycin, cefixime, and ceftriaxone. Gentamicin and spectinomycin reported 100% sensitivity rates. High resistance rates were reported to penicillin, ciprofloxacin, and tetracycline at 80%, 88%, and 68%, respectively.

Conclusion

Regular screening for STIs helps understand the trends and transmission of gonorrhea, which helps initiate appropriate control measures. The resistance to recommended treatment regimens such as azithromycin and cefixime seems to be escalating gradually, probably due to irrational use of antibiotics for non-STI cases and empirical treatment, which needs close monitoring.

Management of Extraocular Infections

Extraocular infection is a frequently encountered problem in children including neonates and infants. Prompt recognition of the extraocular disease and management at first contact reduces the ocular morbidity and visual impairment. Delay in administering appropriate therapy and referral to an eye care personnel may result in blindness; sometimes bilateral, due to severe ophthalmia neonatorum. This review is mainly aimed at offering basic, brief information about common extraocular infections prevalent among infants and children living in developing countries as a ready reference to practising pediatricians and neonatologists. Through this review, the pediatricians, as the first contact may feel confident and comfortable in managing ocular infection in pediatric population particularly living in remote rural and tribal region. Literature search was made by retrieving related publications through peer reviewed journals, PUBMED and Cochrane meta-analysis.

The ABCs of STIs: An Update on Sexually Transmitted Infections

BACKGROUND

Sexually transmitted infections (STIs) are spread primarily through sexual contact and are a major cause of morbidity and mortality worldwide. Once identified, some STIs can be cured following appropriate therapy; for others, suppressive regimens and approaches to prevent ongoing transmission are important. The incidence of many common STIs is increasing in the US as well as worldwide, and hundreds of millions of people are currently infected. Laboratory testing plays a major role in the diagnosis and treatment of STIs, and clinical laboratorians should be familiar with the current guidelines and methods for testing.

CONTENT

Accurate and sensitive methods to diagnose STIs are essential to direct appropriate antimicrobial therapy and interrupt the cycle of disease transmission. This review summarizes laboratory testing for common bacterial, viral, and parasitic causes of STIs. Disease manifestations reviewed include cervicitis and urethritis, genital ulcerative disease, human immunodeficiency virus, viral hepatitis, human papilloma virus, and vaginitis. Recent advancements in the recognition and management of STIs, including updates to diagnostic algorithms, advances in testing methods, and emerging challenges with antimicrobial resistance, are summarized.

SUMMARY

Diagnostic methods and therapeutic guidelines for STIs are rapidly evolving. In combination with changing epidemiology, the development of novel therapeutics, and advancements in diagnostic methods, this has resulted in changing practices in laboratory testing and, subsequently, management of disease. Molecular methods have facilitated personalized therapy and follow-up regimens targeted for individual types or strains of some STIs.

Gonococcal Chorioamnionitis with Antepartum Fetal Death In Utero

We report the case of a patient who developed gonococcal chorioamnionitis resulting in stillbirth at 28 + 4 weeks of pregancy. As this infection is rare and potentially serious, questions remain regarding occurrence and screening for Neisseria gonorrhoeae infection.

The value of simple microbiological studies for on-site screening of acute neonatal conjunctivitis in Angola

BACKGROUND

Neonatal conjunctivitis or ophthalmia neonatorum (ON) is an acute bacterial conjunctivitis contracted by newborns during delivery. In non-industrialized countries, detection of the etiological agent is difficult due to the unavailability of modern diagnostic resources. Therefore, we analyzed the effectiveness of Gram and methylene blue staining techniques, which are simple microbiological methods in suspecting the aetiology of ON in a maternity ward in Luanda, Angola.

FINDINGS

Neonatal conjunctival smears (n = 95), maternal data, and perinatal factors were collected. Slides were air-dried and sent to the Microbiology Department of the Hospital Clinico Universitario, Valladolid, Spain, where trained personnel performed Gram and methylene blue staining methods. Findings were interpreted by two expert microbiologists. Ophthalmological examination of all children showed five newborns with clinical signs of ON. Fourteen mothers reported were suspected with vulvo-vaginitis, and 27 had a urinary infection during pregnancy. Gram staining revealed the presence of epithelial cells in 87.6% and leukocytes in 15% of the conjunctival smears. These values were significantly higher than those shown by methylene blue staining. No rods, cocci, or yeasts were identified by either staining method. Chlamydia trachomatis DNA was also undetected in a small sub-sample with clinical suspicion of ON. There was no correlation among the presence of ON, ON microbes, maternal data, or perinatal factors.

CONCLUSIONS

Basic microbiological techniques did not provide enough information for screening cases of ON in Angola. Therefore, the use of molecular biology or other techniques is warranted for this purpose.

Infectious disease and reproductive health: a review

Human reproduction provides unique opportunities for the transmission of infectious agents. Furthermore, the mother and her offspring have distinct susceptibilities to infection at each stage of reproduction, from conception and gestation to parturition and the neonatal period. The impact of pathogens on reproduction can be mitigated or exacerbated depending on timing of acquisition during pregnancy. Similarly, factors such as maternal immune response, nutritional status, or concurrent infection may modify the effect of an infectious agent. In this review, we discuss the evidence--or lack thereof--for associations between infectious agents and reproductive problems at each stage of reproduction. We focus on well-substantiated associations, and consider several emerging or controversial associations. We discuss the challenges, limitations, and opportunities related to epidemiologic research on infectious disease and reproductive outcomes.

TARGET AUDIENCE

Obstetricians & Gynecologists, Family Physicians.

LEARNING OBJECTIVES

After completion of this article, the reader will be able to describe the potential mechanisms by which infectious agents may impact productive health, explain the public health impact of infectious diseases on reproductive health, and summarize the perinatal risks of infectious disease and relate this to treatment and prevention strategies in practice.
