ABSTRACT

Obesity is a modifiable risk factor for the development and progression of kidney disease. Obesity may harm kidneys in individuals without hypertension, diabetes, or pre-existing renal disease. Ginger, Zingiber officinale, has many beneficial pharmaceutical benefits. This study aimed to evaluate the Zingiber officinale protective effect against obesity complications which induced by high fat diet and caused renal dysfunctions. The study period was two months, and the experimental animals' groups were four, 80 Wistar rats were appropriated similarly 20 animals/group: control group; ginger extract group (GE); high-fat diet (HFD); and GE+HFD group. Body and fat weight, creatinine, leptin, TNF-α, total antioxidants, renal histopathological and ultrastructure were investigated. Rats in group of HFD showed a significant increase (P<0.05) in the body and fat weights, creatinine, leptin and TNF-α, and significant decrease (P<0.05) in total antioxidants (TAS). Ginger administration significantly showed the protective restoring the altered parameters. Furthermore, rats co-treated with ginger extract improved the histopathological and ultrastructural renal injury induced by obesity. The study concluded that the ginger extract used could suppress and decrease the renal damage induced by high-fat diet as it possesses potential medicinal values.


La obesidad es un factor de riesgo modificable para el desarrollo y la progresión de la enfermedad renal. La obesidad puede dañar los riñones en personas sin hipertensión, diabetes o enfermedad renal preexistente. El jengibre, Zingiber officinale, tiene muchos beneficios farmacéuticos. Este estudio tuvo como objetivo evaluar el efecto protector de Zingiber officinale en las complicaciones de la obesidad inducida por una dieta alta en grasas y las enfermedad renal. El período de estudio fue de dos meses, y los grupos de animales experimentales fueron cuatro, se asignaron 80 ratas Wistar de manera similar, 20 animales por grupo: grupo de control; grupo de extracto de jengibre (GE); dieta alta en grasas (DAG); y el grupo GE + DAG. Se evaluó el peso corporal y la grasa, creatinina, leptina, TNF-α, antioxidantes totales, histopatología renal y ultraestructura. Las ratas en el grupo de DAG mostraron un aumento significativo (P<0,05) en el peso corporal y de grasa, creatinina, leptina y TNF-a, y una disminución significativa (P<0,05) en los antioxidantes totales. La administración de jengibre mostró una protección significativa restaurando los parámetros alterados. Además, las ratas tratadas conjuntamente con extracto de jengibre mejoraron la lesión renal histopatológica y ultraestructural inducida por la obesidad. El estudio concluyó que el extracto de jengibre podría suprimir y disminuir el daño renal inducido por la dieta alta en grasas, ya que posee potenciales valores medicinales.

ABSTRACT

Renal histology results are very scarce in dengue-associated rhabdomyolysis patients developing acute kidney injury (AKI). We report a case of dengue fever-induced AKI associated to rhabdomyolysis with a renal biopsy showing acute tubular necrosis (ATN) and renal deposition of myoglobin. A 28-year-old patient who presented dengue fever (DF) complicated by severe AKI and rhabdomyolysis is described. The patient required hemodialysis for three weeks. A renal biopsy revealed ATN with positive staining for myoglobin in the renal tubuli. The patient was discharged with recovered renal function. In conclusion, this case report described a biopsy proven ATN associated to DF-induced rhabdomyolysis, in which renal deposition of myoglobin was demonstrated. We suggest that serum creatine phosphokinase should be monitored in DF patients to allow for an early diagnosis of rhabdomyolysis and the institution of renal protective measures.


Resultados de histologia renal são muito escassos em pacientes com rabdomiólise e injúria renal aguda (IRA) associada a dengue. Descrevemos caso de dengue complicado por rabdomiólise e IRA no qual a biópsia renal mostrou necrose tubular aguda (NTA) e deposição renal de mioglobina. Paciente de 28 anos que apresentou dengue complicado por IRA grave e rabdomiólise é descrito. Ele necessitou de diálise por três semanas. A biópsia renal mostrou NTA, com imunohistoquímica fortemente positiva para mioglobina nos túbulos renais. O paciente recebeu alta com recuperação da função renal. Em conclusão, descrevemos caso de dengue complicado por IRA e rabdomiólise, em que a biópsia renal mostrou NTA e deposição de mioglobina. Sugerimos que creatinofosfoquinase deve ser monitorizada em pacientes com dengue para permitir o diagnóstico precoce de rabdomiólise e a instituição de medidas protetoras para o rim.

ABSTRACT

OBJECTIVE: To document the histological findings in Jamaican children undergoing renal biopsy in order to determine the relative prevalence of varying types of glomerular disease in the island. METHODS: This study analyses retrospectively the renal histology in all Jamaican children less than age 12 years undergoing their first adequate renal biopsy between January 1985 and December 2008. Clinicopathological data were obtained solely from the histology reports from the University Hospital of the West Indies where all paediatric renal biopsies are processed. RESULTS: Of the 270 children, aged 1 month to 11 years (mean 7.58 years), 147 [58.1%] were males. The commonest indications for renal biopsy were nephrotic syndrome (57.4%) and glomerulonephritis (30%). Most biopsied children (260/270) had glomerular disease. The predominant glomerulonephritides were diffuse proliferative glomerulonephritis (DPGN) (27.7%) and mesangialproliferative glomerulonephritis (MesGN) (25.5%). Glomerular disease was idiopathic in 136/260 (53%) but was infection-associated in 32.3% (84 cases) of which Poststreptococcal glomerulonephritis (PSGN) was the commonest (75%) -predominantly DPGN (74.6%). Hepatitis B followed at 15.5% (13/84) manifested as membranous nephropathy in 83.3% (10/12). In patients with SS disease, DPGN was the commonest histology (47.4%). Systemic lupus erythematosus accounted for 5% ofall renal biopsies. Over time, PSGNoccurred less frequently, with a parallel reduction in DPGN and MesGN. CONCLUSION: In Jamaican children, DPGN is the commonest nephritis. Membranous nephropathy is primarily due to Hepatitis B. The commonest histology in SS disease is DPGN. The role ofinfection in the pathogenesis ofrenal disease in Jamaican children is probably underestimated.


OBJETIVO: Documentar los hallazgos histológicos en niños jamaicanos a los que se les ha realizado biopsias renales para determinar la prevalencia relativa de los diversos tipos de enfermedad glomerular en la isla. MÉTODOS: Este estudio analiza retrospectivamente la histología renal en todos los niños jamaicanos menores de 12 años sometidos a su primera biopsia renal adecuada entre enero de 1985 y diciembre de 2008. Los datos clinicopatológicos fueron obtenidos exclusivamente de los reportes de histología del Hospital Universitario de West Indies, dónde se procesan todas las biopsias renales. RESULTADOS: De 270 niños, cuyas edades fluctuaban de 1 mes a 11 años (media 7.58 años), 147 [58.1%] eran varones. Las indicaciones más comunes para la biopsia renal fueron el síndrome nefrótico (57.4%) y la glomerulonefritis (30%). La mayoría de los niños sometidos a biopsia (260/270) tenían la enfermedad del glomerular. Las glomerulonefritis predominantes fueron la glomerulonefritis proliferativa difusa (GNPD) (27.7%) y glomerulonefritis proliferativa mesangial (GNMes) (25.5%). La enfermedad glomerular fue idiomática en 136/260 (53%) pero estuvo asociada con infecciones en 32.3% (84 casos) en los cuales la glomerulonefritis poststreptocóccica (GNPS) fue la más común (75%) - predominantemente GNDP (74.6%). La hepatitis B siguió con 15.5% (13/84), manifestada como nefropatía membranosa en 83.3% (10/12). En los pacientes con la enfermedad de la hemoglobina SS, la GNDP fue la histología más común (47.4%). El lupus eritematoso sistémico representó el 5% de todas las biopsias renales. Al pasar el tiempo, la GNPS ocurrió menos frecuentemente, con una reducción paralela en GNPD y GNMes. CONCLUSIÓN: En los niños jamaicanos, la GNPD es la nefritis más común. La nefropatía membranosa se debe principalmente a la Hepatitis B. La histología más común en el caso de la enfermedad de hemoglobina SS es la GNPD. Probablemente se subestima el papel que las infecciones desempeñan en la patogénesis de la enfermedad renal en los niños jamaicanos.

ABSTRACT

This paper emphasizes the importance of the mechanism of renal tissue damage in conducting treatment of lupus nephritis in addition to the renal histology.There are at least 4 kinds of mechanisms related to the renal tissue damage of LN including circulating immune complex deposition,in situ immune complex formation,vasculitic change and thrombotic mircoangiopathy.Treatment according to the mechanisms of tissue damage will give rise to a much better result as compared with the classic treatment based on morphology alone.Multi-target immune theapy has been recommended for treatment of those severe and complicated LN.
