Leprosy, also known as morbus Hansenʼs disease, is a chronic disease caused by M. leprae. Leprosy attacks various parts of the body including nerves and skin. The most important factor in the occurrence of leprosy is the sources of transmission and contact, both from patients and the environment. Household conditions where the person lives and the nutritional status of the individual can be a risk factor for leprosy. Household hygiene and sanitation can be seen from several aspects, like the physical environment of the house, clean water facilities, personal hygiene, availability of latrines, waste disposal facilities, and garbage disposal. This study was aimed to determine the correlation between household hygiene sanitation and nutritional status with females with leprosy in Gresik Regency. This case-control study was conducted in December 2019 in Gresik Regency. The subjects of this study were 74 respondents taken by consecutive sampling techniques. Retrieval of data was carried out using observations from the healthy house component questionnaire, personal hygiene questionnaire, and direct measurement. Data were analyzed using the chi-square test. The results showed significant correlation between physical environment of the house ( , OR = 0.104), clean water facilities ( , OR = 0.261), availability of latrines ( , OR = 0.209), waste disposal facilities ( , OR = 0.291), and personal hygiene ( , OR = 2.850) and female leprosy in Gresik Regency. There is no correlation between nutritional status ( , OR = 0.422) and wastewater disposal waste ( , OR = 0.486) and female leprosy in this study.

Background: Aging among people living with HIV (PLWH) presents multifaceted challenges influenced by antiretroviral therapy (ART), chronic inflammation, viral coinfections, stigma, multimorbidity, and immunosuppression. Methods: This review synthesizes recent research findings to outline factors contributing to aging with HIV. A comprehensive literature search was done using electronic databases including PubMed, Web of Science, Google Scholar, and CINAHL with keywords “HIV,” “Aging,” “Elderly,” “Geriatrics,” “Older Adults,” “HIV Infections,” and “HIV/AIDS. Results: Addressing age‐related comorbidities, cognitive impairment, and non‐AIDS events is imperative as older PLWH face increased morbidity and mortality rates compounded by coinfections such as HCV, HPV, TB, HSV, and bacterial infections. While ART is vital for viral suppression, it introduces challenges such as mitochondrial toxicity, metabolic disorders, and decreased CD4 cell counts, accelerating the aging process. Lifestyle factors, including smoking, substance abuse, malnutrition, sedentary behavior, and mental health conditions, further exacerbate aging in PLWH. Conclusions: This study emphasizes the necessity of holistic approaches to meet the unique healthcare needs of older PLWH, with insights into immunosenescence, coinfections, disease progression, ART exposure, and lifestyle factors. Understanding these dynamics is crucial for improving health outcomes and quality of life in aging PLWH.

Lymphocytes are found in blood and lymph. Besides Natural killer (NK) cells, T cells and B cells are the different forms of lymphocytes. Each of these cells plays fundamental role in the body adaptive immune response. B lymphocytes are central players in the immune response; canonically, they have been recognized as precursors of antibody-producing cells: plasma cells. Recent findings have shown that the role of B lymphocytes goes far beyond the production of antibodies. There are different subtypes of B lymphocytes with different participations in innate and adaptive responses that include the recognition of the antigen, its processing, and its presentation to T lymphocytes, as well as the production of cytokines that impact and modulate the response toward the pathogen. Traditionally, it has been considered that B lymphocytes do not have phagocytic abilities that allow them to internalize, to process, or even to be infected by bacterial pathogens. The new information has shown that B lymphocytes can be readily infected by bacterial pathogens and respond to those infections. T lymphocytes play a role in cytotoxic immune responses. They belong to the adaptive immune system and perform a wide array of functions in immune regulation, inflammation and protective immune responses. In recent years, it has been shown that T cells are involved essentially across the entire spectrum of tissue physiology and pathology, not just in reactions or diseases considered to be bonafide immunological, but also, to cite just some examples, in metabolism, in tissue repair, in dysbiosis, and in pregnancy. Basic research on T cells has also sown the seeds that spawned the new era of immunotherapy that is engaging numerous researchers in finding a cure for cancer. The review of this article aims to further understand the latest findings regarding the formation and work mechanism of lymphocytes, especially on adaptive immunity. It summarizes the various forms of lymphocytes and their immunomodulatory roles in health and diseases.

Background: Leprosy is a disease that causes social, psychological, and economic issues. Failure to treat the causes of the immune system dysregulation in endemic areas of leprosy conditions makes the transmission of the bacteria easier. This paper aims to analyze the comparison of family income, occupation types of mothers and fathers, number of children, access to health facilities, and education of mothers, fathers, and children in mothers and children with leprosy in endemic and non-endemic areas. Materials and Methods: A cross sectional study by survey was done in both an endemic and a non-endemic area of leprosy in Tuban Regency, East Java, Indonesia. Retrieval of research data was done using interview techniques. Respondents who participated in this study were 106 pairs of mother and child respondents who met the research restriction criteria. Subjects were divided into 5groups based on diagnosis of leprosy and area of living. Bivariate analysis was performed by comparing the independent variables in each group A, B, C, and D with group E. Results:It was found that the variables that differed significantly between the endemic and non-endemic areas were the variable number of children with a p-value=0.004, family income with a p-value=0.049 and the variable mother’s education with a p-value=0.016. Meanwhile, other variables do not have significant difference. Conclusions:We found significant difference on the number of children, father’s education, mother's education, and family income. These variables can be a risk factor for leprosy. To make efforts to prevent the transmission of leprosy, stakeholders should consider these factors.

Acid-fast staining has been utilized in the field of medicine since the late 1800s. It was, for a while, considered the gold standard for diagnosing leprosy and tuberculosis. Principally it uses 1 primary staining agent, carbol fuchsin; and methylene blue as a counter stain. The emergence of molecular-based diagnostic tests makes some of us question the relevance of acid-fast staining in daily practice. This literature review aimed to revisit the acid-fast staining method, its uses, and the modification that occurred throughout the years.

Leprosy, a chronic infection caused by M. leprae, has a complex transmission problem that makes eradication programs difficult. New cases and ongoing transmission of leprosy in endemic areas make individuals living in endemic environments vulnerable to leprosy. This can be caused by the dysregulation of immune system in individuals living in leprosy-endemic areas. Although the number of male leprosy patients is higher, female leprosy patients have more impact on the family health status due to close contact with family members, roles in the household, and parenting. This could cause the increased number of children leprosy patients. We investigated the dysregulation of immune system by comparing IL-17 and FOXP3+ levels occurring in maternal and child leprosy patients in endemic and nonendemic areas. The results of the study found a statistically significant difference in IL-17 levels between the MB leprosy patient group and the control group ( p = 0.048 ), where higher levels of IL-17 are observed in the control group. A significant difference also was found in FOXP3+ levels between the group of healthy children living in endemic and those living in nonendemic areas ( p = 0.047 ), where higher FOXP3+ is observed in the healthy children living in endemic areas group.
