    Insights

    Kidney biopsies in 54 leprosy patients revealed significant renal lesions, most commonly membranous glomerulonephritis. These findings indicate that leprosy can affect kidney health across all its types.

    Area of Science:

    • Nephrology
    • Infectious Diseases
    • Immunology

    Background:

    • Leprosy is a chronic infectious disease caused by Mycobacterium leprae.
    • Renal involvement in leprosy is a recognized but not fully understood complication.
    • Understanding the spectrum of kidney lesions in leprosy is crucial for patient management.

    Purpose of the Study:

    • To investigate the prevalence and types of kidney lesions in patients with leprosy.
    • To correlate renal pathology with leprosy types.
    • To explore potential mechanisms of renal tissue reaction to M. leprae.

    Main Methods:

    • Analysis of kidney biopsy findings in 54 leprosy patients.
    • Classification of leprosy types: lepromatous (45 cases), tuberculoid (4 cases), and borderline (5 cases).
    • Histopathological examination to identify glomerular and other renal lesions.

    Main Results:

    • Renal lesions were observed in patients across all leprosy types studied.
    • Membranous glomerulonephritis was the most frequent glomerular lesion (31.5%).
    • Mesangioproliferative glomerulonephritis was also identified (11.1%).

    Conclusions:

    • Renal lesions are a common occurrence in leprosy, irrespective of the disease type.
    • The pathogenesis of renal lesions may involve local immunologic or physiological responses to M. leprae.
    • Further research is warranted to elucidate the precise mechanisms and long-term implications of renal involvement in leprosy.

    Abnormal Proliferation

    Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

    Pulmonary Tuberculosis III

    Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
    The first classification is based on the development of the disease, and it includes the following categories:
    Leishmaniasis01:30

    Leishmaniasis

    Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...

    Antiprotozoal Agents

    Leishmaniasis is a widespread parasitic disease caused by several Leishmania species. It affects millions of people each year and remains a major public health problem in endemic regions. First-line treatment relies on pentavalent antimonials, including meglumine antimoniate and sodium stibogluconate. Even so, how these drugs work has not been fully clear, especially their interaction with parasite-specific biochemical pathways. One key target is trypanothione reductase (TR), an enzyme that...
