Lower Urinary Tract Symptoms (LUTS) as a New Clinical Presentation of Histamine Intolerance: A Prevalence Study of Genetic Diamine Oxidase Deficiency.

Lower urinary tract symptoms (LUTS) are highly prevalent, and their treatment is mainly focused on the control of symptoms. Histamine intolerance (HIT) has been related to a variety of systemic symptoms. DAO deficiency has been identified as a significant factor contributing to histamine intolerance (HIT). Preclinical evidence indicates the involvement of histamine in the lower urinary tract. This study aimed to assess the prevalence of diamine oxidase deficiency (DAO) in a prospective cohort of 100 patients with at least moderate LUTS. A genetic study of four single nucleotide polymorphisms (SNPs) (c.-691G>T, c.47C>T, c.995C>T, and c.1990C>G) was performed. HIT was found in 85.9% of patients. The prevalence of at least one minor allele in the SNPs analyzed was 88%, without gender differences. Storage symptoms were more intense in the presence of HIT as well as asthenia and neurological and musculoskeletal symptoms. The presence of minor alleles of the AOC1 gene was associated with a higher intensity of symptoms. Minor alleles from c.-691G>T and c.47C>T SNPs were also associated with a greater severity of obstructive symptoms. Thirty-one percent of patients presented the four SNPS with at least one associated minor allele. The relationship between HIT and LUTS in a mixed population of men and women found in this study supports further investigations to define the pathophysiology of histamine in LUTS.

Prostatitis y retención aguda de orina como comienzo de granulomatosis de Wegener / Prostatitis and acute urinary retention as first manifestations of Wegener's granulomatosis

Objetivos. Presentar un caso de prostatitis con retención aguda de orina como manifestación inicial poco frecuente de granulomatosis de Wegener. Métodos. Se presenta el caso de un varón de 48 años con un cuadro de prostatitis de 10 días de evolución, que presentó retención de orina, con respuesta parcial al tratamiento antibiótico, y con niveles elevados de anticuerpos citoplasmáticos contra los neutrófilos con patrón citoplasmático y estudio anátomo-patológico de la biopsia prostática compatible con granulomatosis de Wegener. Resultados. Tras el inicio de tratamiento mediante glucocorticoides y ciclofosfamida se observa mejoría notable de los síntomas hasta su desaparición. A los 3 meses inicia clínica pulmonar y de vías aéreas superiores, precisando para el control de sus síntomas dosis mayores de ciclofosfamida. Conclusiones. La granulomatosis de Wegener es una entidad multisistémica cuya forma de presentación como prostatitis con retención de orina es poco frecuente (AU)

Objectives. We present a case of prostatitis with acute urinary retention as a rare initial manifestation of Wegener's granulomatosis. Methods. The case was a 48-year-old male with symptoms of prostatitis over 10 days. The patient presented urinary retention, with partial response to antibiotic treatment. High levels of cytoplasmic antineutrophil cytoplasmic antibody and a prostatic biopsy were compatible with Wegener's granulomatosis. Results. After starting treatment with glucocorticoids and cyclophosphamide, a significant improvement to the point of disappearance of symptoms was observed. At 3 months pulmonary and upper airway symptoms began, requiring higher doses of cyclophosphamide to control symptoms. Conclusions. Wegener's granulomatosis is a multisystem entity whose presentation as prostatitis with urinary retention is rare (AU)

Prostatitis and acute urinary retention as first manifestations of Wegnener's granulomatosis.

OBJECTIVES: We present a case of prostatitis with acute urinary retention as a rare initial manifestation of Wegener' Granulomatosis. METHODS: The case was a 48-year-old male with symptoms of prostatitis over ten days. The patient presented urinary retention, with partial response to antibiotic treatment. High levels of cytoplasmic antineutrophil cytoplasmic antibody and a prostatic biopsy were compatible with Wegener' Granulomatosis. RESULTS: After starting treatment with glucocorticoids and cyclophosphamide, a significant improvement to the point of disappearance of symptoms was observed. At 3 months pulmonary and upper airway symptoms began, requiring higher doses of cyclophosphamide to control symptoms. CONCLUSIONS: Wegener's Granulomatosis is a multisystem entity whose presentation as prostatitis with urinary retention is rare.
