Abstract
Aims: Human breast milk remains an important source of protection against infection, inflammation, allergy and long-term metabolic disorders for the breastfed offspring. During cases of ongoing infection, the dilemma faced by both medical health professionals and mothers is the need to balance the risk of continuing versus temporarily or permanently ceasing to breastfeed. The aim of our article is to review existing literature regarding breastfeeding during acute infectious and non-infectious illnesses and to provide feasible evidence-based suggestions which can be implemented by medical practitioners during counselling of breastfeeding mothers. Method: A literature search was conducted on PubMed (US National Library of Medicine) using various combinations of keywords related to breastfeeding and the various infections. The citations from all selected articles were reviewed for additional studies. Results: Most ongoing infections are not contraindications for breastfeeding, with the exceptions of Human Immunodeficiency viruses (HIV), Human T-cell lymphotropic virus (HTLV) types 1 and 2. Even with HIV, there is increasing evidence to reassure that with adequate antiretroviral therapy, breastfeeding is likely to be safe. Of particular concern during the COVID-19 pandemic too, current evidence indicates that mothers with COVID-19 infection can safely breastfeed, and therefore initiation and continuation of breastfeeding should continue to protect the health of the babies and mothers. Conclusion: During this pandemic especially, there is a strong and urgent need to support mothers with acute infections who wish to breastfeed. With better awareness, physicians can play an important role in securing positive experiences for breastfeeding mothers and optimizing infant outcomes.

Abstract
BACKGROUND In terms of maternal morbidity and mortality, the puerperium is just as significant as pregnancy and childbirth. Nearly half of all maternal deaths occur in the time after delivery. METHODS This review is based on pertinent articles in English and German from the years 2000- 2020 that were retrieved by a selective search in MEDLINE and EMBASE, as well as on the available guidelines in English and German and on German-language textbooks of obstetrics. RESULTS The most common and severe complications are, in the post-placental phase, bleeding and disturbances of uterine involution; in the first seven days after delivery, infection (e.g., endomyometritis, which occurs after 1.6% [0.9; 2.5] of all births) and hypertension-related conditions. Thromboembolism, incontinence and disorders of the pelvic floor, mental disease, and endocrine disturbances can arise at any time during the puerperium. In an Australian study, the incidence of embolism was 0.45 per 1000 births, with 61.3% arising exclusively after delivery. CONCLUSION Basic familiarity with the most common and severe diseases in the puerperium is important for non-gynecologists as well, among other things because highly acute, lifethreatening complications can arise that demand urgent intervention.

Abstract
Candidiasis is a common opportunistic infection caused by fungi of the Candida genus that affects mainly mucocutaneous tissues (e.g., vaginal, oral, and mammary). This condition has been known for a long time; thus, innumerous topical and systemic treatments are already available on the market worldwide. Yet, recurrent superficial candidiasis (RSC) is an expected outcome, still lacking effective and convenient treatments. Although several individual conditions may contribute to disease recurrence, biofilms' presence seems to be the main etiological factor contributing to antifungal resistance. More than proposing novel antifungal agents, current research seems to be focusing on improving the pharmaceutical technology aspects of formulations to address such a challenge. These include extending and improving intimate contact of drug delivery systems with the mucocutaneous tissues, increasing drug loading dose, and enhancing topical drug permeation. This review discusses the current understanding of the RSC and the use of pharmaceutical technology tools in obtaining better results. Even though several drawbacks of conventional formulations have been circumvented with the help of nano- or microencapsulation techniques and with the use of mucoadhesive formulation excipients, many challenges remain. In particular, the need to mask the unpalatable taste of formulations for the treatment of oral candidiasis, and the necessity of formulations with a "dryer" sensorial feeling and improved performances in providing higher bioavailability for the treatment of mammary and vaginal candidiasis.

[PMID: 34269140 PMCID: PMC8287641 DOI: 10.1177/17455065211031480] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Revised: 06/22/2021] [Accepted: 06/22/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Breastfeeding mothers commonly experience nipple pain accompanied by radiating, stabbing or constant breast pain between feeds, sometimes associated with pink shiny nipple epithelium and white flakes of skin. Current guidelines diagnose these signs and symptoms as mammary candidiasis and stipulate antifungal medications. AIM This study reviews existing research into the relationship between Candida albicans and nipple and breast pain in breastfeeding women who have been diagnosed with mammary candidiasis; whether fluconazole is an effective treatment; and the presence of C. albicans in the human milk microbiome. METHOD The author conducted three searches to investigate (a) breastfeeding-related pain and C. albicans; (b) the efficacy of fluconazole in breastfeeding-related pain; and (c) composition of the human milk mycobiome. These findings are critiqued and integrated in a narrative review. RESULTS There is little evidence to support the hypothesis that Candida spp, including C. albicans, in maternal milk or on the nipple-areolar complex causes the signs and symptoms popularly diagnosed as mammary candidiasis. There is no evidence that antifungal treatments are any more effective than the passage of time in women with these symptoms. Candida spp including C. albicans are commonly identified in healthy human milk and nipple-areolar complex mycobiomes. DISCUSSION Clinical breastfeeding support remains a research frontier. The human milk microbiome, which includes a mycobiome, interacts with the microbiomes of the infant mouth and nipple-areolar complex, including their mycobiomes, to form protective ecosystems. Topical or oral antifungals may disrupt immunoprotective microbial homeostasis. Unnecessary use contributes to the serious global problem of antifungal resistance. CONCLUSION Antifungal treatment is rarely indicated and prolonged courses cannot be justified in breastfeeding women experiencing breast and nipple pain. Multiple strategies for stabilizing microbiome feedback loops when nipple and breast pain emerge are required, in order to avoid overtreatment of breastfeeding mothers and their infants with antifungal medications.

Abstract
Certain dermatologic conditions are unique to the breast and nipple, whereas others may incidentally involve these structures. All require a nuanced approach to diagnosis and treatment because of the functional, sexual, and aesthetic importance of this area. The lactating patient requires special management because certain treatment options are contraindicated. All dermatologic conditions involving the breast and nipple require careful evaluation because malignancy of the breast can be mistaken for a benign condition or may trigger the development of certain dermatologic conditions. The second article in this continuing medical education series reviews common and uncommon inflammatory and infectious conditions of the breast and nipple and provides insight into both the diagnosis and the treatment of this heterogeneous group of diseases. For the purposes of this article, these conditions are divided into 4 distinct categories: 1) dermatitis; 2) radiation-induced changes; 3) mastitis; and 4) miscellaneous dermatologic conditions of the breast and nipple.

Abstract
Inflammation and infection postpartum threaten the mother and her infant. Human milk provides a defense for the infant, but inflammatory complications like mastitis may lead to the cessation of breastfeeding. Antisecretory factor (AF) has a role in the regulation of secretory processes and inflammation. The objective of the study was to describe AF-levels in plasma and breast milk, and in relation to breast complications. Breastfeeding mothers (n = 95) were consecutively recruited at a Well Baby Clinic in Umeå, Sweden. At inclusion four weeks postpartum, samples of venous blood (10 mL) and breast milk (10 mL) were collected. Active AF was analyzed with ELISA using a monoclonal antibody mAb43, and was detected in all samples of plasma and breast milk with a positive correlation (Spearman coefficient = 0.40, p < 0.001; Pearson correlation = 0.34, p < 0.01). High AF-levels in plasma correlated with high AF-levels in breast milk. The results suggest a co-regulation between active AF in plasma and breastmilk, and/or a local regulation of AF in the breast. Further studies are needed to determine the pathways for the activation of AF-levels in breast milk and plasma.

Abstract
Background Deep breast pain during lactation, with or without accompanying nipple pain and soreness continues to be anecdotally linked to infection by Candia albicans despite lack of robust evidence in the literature that Candida albicans is the cause of women’s breast symptoms. Methods A case-control study of breastfeeding women in Sweden with (n 35) and without (n 35) symptoms that may be attributable to Candida albicans was carried out. The symptoms were radiating, burning and penetrating or non-penetrating breast pain with or without associated nipple pain during or after breastfeeding. The primary aim of the study was to test the hypothesis that breastfeeding women with symptoms commonly associated with Candida albicans infection will have a growth of Candida albicans in their breast milk significantly more often than women without these symptoms. A secondary aim was comparison of breastfeeding self-efficacy, measured by the BSES-SF (Breastfeeding Self Efficacy Scale –Short Form), between cases and controls. Results None of the women in the control group and eight of the women in the case group showed a growth of Candida albicans in their breast milk (p < 0.01), which confirms the hypothesis. There were no statistically significant differences in severity or type of symptoms between those in the case group with and without growth of Candida albicans in their breast milk. Results of the BSES-SF measurement showed no statistically significant differences between cases and controls. However, when analyses were stratified for parity, multiparous controls showed statistically significant higher scores for breastfeeding self-efficacy than multiparous cases. Conclusions Neither clinical symptoms nor microbial cultivation appear to be reliable means for making a diagnosis of Candida albicans infection of the breast. Skilled breastfeeding consultants should offer support and help with positioning, attachment and identification of physical impediments to successful breastfeeding. Professionals should be aware that it is possible that uncertainty in the breastfeeding situation may to some extent account for mothers’ breast symptoms. The ISRCTN (International Standard Randomised Controlled Trial Number) identity for this case-control study is ISRCTN88839993. The study was retrospectively registered on 30 November 2016.

Abstract
Many physicians, midwives and lactation consultants still believe that yeasts (particularly Candida spp.) play an important role as an agent of nipple and breast pain despite the absolute absence of scientific proofs to establish such association. In this context, the objective of this study was to investigate the microorganisms involved in sore nipples and/or painful "shooting" breastfeeding by using a variety of microscopy techniques, as well as culture-dependent and-independent identification methods. Initially, 60 women (30 diagnosed as suffering "mammary candidiasis" and 30 with no painful breastfeeding) were recruited to elucidate the role of their pumps on the milk microbial profiles. After realizing the bias introduced by using such devices, manual expression was selected as the collection method for the microbiological analysis of milk samples provided by 529 women with symptoms compatible with "mammary candidiasis". Nipple swabs and nipple biopsy samples were also collected from the participating women. Results showed that the role played by yeasts in breast and nipple pain is, if any, marginal. In contrast, our results strongly support that coagulase-negative staphylococci and streptococci (mainly from the mitis and salivarius groups) are the agents responsible for such cases. As a consequence, and following the recommendations of the US Library of Medicine for the nomenclature of infectious diseases, the term "mammary candidiasis" or "nipple thrush" should be avoided when referring to such condition and replaced by "subacute mastitis".

Abstract
A central goal of The Academy of Breastfeeding Medicine is the development of clinical protocols for managing common medical problems that may impact breastfeeding success. These protocols serve only as guidelines for the care of breastfeeding mothers and infants and do not delineate an exclusive course of treatment or serve as standards of medical care. Variations in treatment may be appropriate according to the needs of an individual patient.

Abstract
BACKGROUND Although breast pain remains a common cause of weaning, controversy exists regarding the etiology of chronic pain. Prospective studies are needed to define optimal treatment regimens. We evaluated patient history, exam, and bacterial cultures in breastfeeding women with chronic breast pain. We compared pain resolution and breastfeeding complications in patients responding to conservative therapy (CTX) (n=38) versus those in patients failing CTX and receiving oral antibiotic treatment (OTX) (n=48). SUBJECTS AND METHODS We prospectively enrolled 86 breastfeeding women with breast pain lasting greater than 1 week and followed up patients through 12 weeks. RESULTS Higher initial breast (p=0.012) and nipple pain severity (p=0.004), less response to latch correction (p=0.015) at baseline visit, and breastmilk Staphylococcus aureus growth (p=0.001) were associated with failing CTX. Pain type was not associated with failure of CTX. When culture results were available at 5 days, breast pain remained higher (p<0.001) in patients failing CTX and starting antibiotics. OTX patients then had more rapid breast pain reduction between 5 and 14 days (score of 3.1 vs. 1.3; p<0.001). By 4 weeks there was no difference (1.8/10 vs. 1.4/10; p=0.088) in breast pain level between groups. Median length of OTX was 14 days. At 12 weeks, weaning frequency (17% vs. 8%; p=0.331) was not statistically different. CONCLUSIONS Initial pain severity and limited improvement to latch correction predicts failure of CTX. S. aureus growth is more common in women failing CTX. For those women not responding to CTX, OTX matched to breastmilk culture may significantly decrease their pain and is not associated with increased complications.

Abstract
BACKGROUND An infectious etiology for chronic breast pain in breastfeeding women continues to be debated. Although recent data suggest that Staphylococcus aureus and coagulase-negative Staphylococcus (CNS) may cause chronic breast pain, no studies have used quantitative cultures to address this question. In this study we compared bacterial species and colony counts between breastfeeding women with (cases) and without (controls) chronic pain. SUBJECTS AND METHODS We enrolled 114 breastfeeding women in a prospective cohort study. Cases (n=61), breastfeeding women with breast pain for >1 week and no signs of acute infection, were matched with controls (n=53) by weeks postpartum and parity. RESULTS More cases had a history of mastitis (14% vs. 2%, p=0.036), cracked nipples (64% vs. 17%, p=0.001), and other breastfeeding difficulties. Enterobacter species growth was less likely in cases (0% vs. 7.5%, p=0.029). Cases had a significantly higher growth of S. aureus (19.7% vs. 1.9%, p=0.003). CNS frequency was similar between groups (75% vs. 79%, p=0.626), but median colony count growth was significantly lower in cases (900 colony-forming units/mL vs. 5,000 colony-forming units/ml, p=0.003). Growth of CNS and S. aureus was negatively correlated (r=-0.265, p=0.004). CONCLUSIONS Higher S. aureus growth in cases supports a pathogenic role for S. aureus and reinforces the need for future antibiotic treatment studies in breastfeeding women with chronic pain. In contrast, similar CNS frequency between groups, lower CNS colony counts in cases, and a negative correlation between S. aureus and CNS growth suggest that neither CNS, nor its overgrowth, causes chronic breast pain.

Abstract
INTRODUCTION Controversy over the etiology of deep or burning breast pain during lactation continues to persist, despite a long history of published studies and case reports. This article reviews the literature exploring the etiology of deep breast pain, summarizes the results, and identifies possible explanations for the controversies surrounding this disorder. METHODS A clinical query and a librarian-assisted search of MEDLINE were used to find articles published between 1896 and 2010. Inclusion criteria consisted of comparing microbial testing results from symptomatic and asymptomatic lactating women. Cases were restricted to those experiencing deep or burning breast pain when possible. RESULTS Prospective studies consisting of 1 unmatched case-control and 6 cohorts were found. Trials typically detected higher microbial levels in the milk or nipple(s) or both of symptomatic women, irrespective of the detection method or type and range of microbes (bacterial, yeast, or fungal) studied. Case milk samples were positively associated with finding Staphylococcus aureus (relative risk ratio [RR] 7.29; 95% confidence interval [CI], 3.25-16.36) or Candida (RR 8.45; 95% CI, 3.96-18.06). Moreover, recent reports about small-colony variants and biofilm-producing organisms may explain the atypical symptoms unique to this disorder. DISCUSSION In lactating women reporting deep breast pain, evidence consistent with infection is persistently found, and explanations exist for the disorder's atypical characteristics. Although lactating women with deep breast pain are more likely to test positive for Candida, the risk of testing positive for S aureus is also present. Thus, these women should have cultures done. Management options include treating immediately while awaiting results or waiting until results are available to guide treatment. With either approach, providers must consider the risk of falsely negative tests.

Abstract
We evaluated all Candida spp. isolates obtained from patients admitted to two tertiary care hospitals between 1999 and 2003 in the city of São Paulo, Brazil. The in vitro activities of fluconazole (FCZ) and voriconazole were determined by the agar disk diffusion test using the Clinical and Laboratory Standards Institute M44-A guidelines. The inhibition zone diameters were read and interpreted automatically by the BIOMIC(®) image-analysis plate reader system. We tested a total of 4,625 strains, including 2,393 strains of C. albicans (51.7%), 658 of C. tropicalis (14.2%), 503 of C. glabrata (10.9%), 495 of C. parapsilosis (10.7%), 292 of C. rugosa (6.3%), 195 of C. guilliermondii (4.2%) and 89 of other Candida species (2.0%). Only 2.0% of the strains tested were classified as dose-dependent susceptible (DDS), and 5.8% of them were resistant to FCZ. The resistance or DDS to fluconazole was verified mainly among C. glabrata (7.8%), C. krusei (67.9%) and C. rugosa (65.1%). Voriconazole exhibited better activity in vitro than fluconazole, even in isolates fluconazole resistant. The resistance of fluconazole and voriconazole did not increase in the isolates of Candida spp. during the evaluated period.
