Impact of sodium-glucose cotransporter-2 inhibitors-induced glucosuria in the incidence of urogenital infection on postmenopausal women with diabetes.

BACKGROUND: Type 2 diabetes mellitus (T2DM) in postmenopausal women is associated with a high incidence of urogenital infections, which negatively impact the quality of life and increase morbidity, mortality, and health-care costs. Glucosuria is a known risk factor for these infections; therefore, it is of interest to determine if increased glucosuria secondary to sodium-glucose cotransporter-2 inhibitors (SGLT2in) impacts the incidence and severity of urogenital infections in postmenopausal women with T2DM. METHODS: The study was conducted at Gaffrée Guinle University Hospital on two groups of postmenopausal women with T2DM: with and without SGLT2in therapy (n = 80 in each group). Medical records and laboratory parameters (urinary dipstick test and culture; blood glucose, glycosylated hemoglobin, and creatinine; cervical cytologic study) of all subjects were carefully assessed at baseline and thrice during the 12-month study period. RESULTS: We observed a significant incidence of vulvovaginitis (relative risk [RR], 2.37; 95% confidence interval [CI], 1.10-5.10; P = 0.03) and asymptomatic bacteriuria (RR, 2.47; 95% CI, 1.09-5.60; P = 0.03), but not of urinary tract infections (RR, 2.08; 95% CI, 0.74-5.81; P = 0.16), secondary to SGLT2in therapy. Genital infection was severe enough to warrant treatment discontinuation in 57.89% of patients in group 1. All urinary tract infections were of mild intensity with a good response to antibiotic therapy. CONCLUSION: Glucosuria induced by SGLT2in therapy may lead to a high incidence of urogenital infections in postmenopausal women with T2DM and can be considered a risk factor for these infections.

Effect of ultrafiltration on placental-fetal blood flow in pregnancy of woman undergoing chronic hemodialysis.

INTRODUCTION: Patient who was undergoing hemodialysis (HD) thrice weekly usually gain 1 to 4 kg of weight in interdialytic period, mainly due to fluid accumulation by ingestion of water. Ultrafiltration (UF) during HD will be need to remove fluid excess to avoid severe medical complications secondary to fluid overload. However, in pregnant woman UF can increase the episodes of intradialytic hypotension which may lead to placental ischemic injury and predispose to fetal distress. There is little information about safe fluid amount withdrawn by UF during pregnancy. METHODS: We prospectively study by obstetric Doppler ultrasonography the fluxometric parameters: pulsatility index (PI) and resistance index (RI) of fetal middle cerebral, uterine, and umbilical artery obtained at the beginning and the end of HD session, the acute and chronic effect of UF on placenta and fetus blood flow, as well as the fetal outcome in 1 pregnant woman on chronic HD. FINDINGS: We did not observe any acute harmful effect on fetal middle cerebral, placental and umbilical artery blood flow when UF rate of 2.1 ± 0.04 L (6 < 8 mL/h/kg) during HD session, no significant statistical difference was observed when compared PI and RI before and after UF and also when we compared these data with reference value on normal pregnancy to the same gestational age. DISCUSSION: UF rate of 6 < 8 mL/h/kg during HD did not bring any acute harmful effect on fetal middle cerebral, placental, and umbilical blood flow and the UF rate of 1.4 6 0.4 L (< 6 mL/h/kg) / HD session that was done in all others HD during pregnancy was safe, without any chronic fetal deleterious effect. Obstetric Doppler ultrasonography is a simple and noninvasive method to fetal follow-up and can aid to determine safe UF rate in pregnant women during gestation.

Refractory pemphigus vulgaris treated with rituximab and mycophenolate mofetil

The main treatment for pemphigus vulgaris are systemic corticosteroids and immunosuppressive agents, but due to adverse reactions and therapeutic failure, new drugs such as rituximab and mycophenolate mofetil have been used. In this case report are described two cases of severe pemphigus vulgaris refractory to various treatments, with resolution after use of rituximab and mycophenolate mofetil, associated with corticosteroids. A higher-than-usual dose of rituximab was employed, without the occurrence of serious adverse reactions. Mycophenolate mofetil was added as adjunctive therapy due to lack of response to azathioprine.

Epidemiological and clinical aspects of urinary tract infection in community-dwelling elderly women

BACKGROUND: Urinary tract infections (UTIs) in elderly patients can be a complex problem in terms of approach to diagnosis, treatment, and prevention, because the patients often present nonspecific symptoms. The epidemiological and clinical characteristics of UTI in elderly women were studied, in order to make early diagnosis and prevent serious clinical complications secondary to UTI. METHODS: This was a prospective population-based study, with elderly women, during their first medical office visit. Medical records were obtained by clinical history and physical examination in order to detect signs and symptoms of UTI and the presence of comorbidities. Clean-catch midstream urine specimens for urinary dipstick test, sediment, and culture were collected; cervical samples for conventional Pap smears were also collected. RESULTS: UTI was found in 16.55% of elderly women. The most frequent urinary symptom was foul smelling urine, in 60.6%. E. coli was responsible for 98 (76.56%) cases of significant bacteriuria; 34 (34.69%) were resistant to trimethoprim-sulfamethoxazole, and 21 (21.42%) to fluoroquinolones. Asymptomatic bacteriuria (AB) was not treated. The presence of predisposing factors demonstrated that the history of previous UTI (p < 0.001), vaginitis (p < 0.001), and diabetes (p = 0.042) increased the risk for UTI. CONCLUSION: This study confirmed the high prevalence of UTI among elderly women and its unusual clinical presentation. Diabetes, history of previous UTI, and vaginitis were shown to be predisposing factors for UTI; it is not necessary to treat AB in elderly women, even among diabetics.

Effects of pregnancy on the onset and progression of diabetic nephropathy and of diabetic nephropathy on pregnancy outcomes.

Controversy exists regarding the effect of pregnancy on the development and course of diabetic nephropathy. This study followed 43 pregnant women with previous diabetes mellitus, 32 without nephropathy (Group I) and 11 with nephropathy (Group II). Urinary albumin excretion (UAE), serum creatinine (Cr) and creatinine clearance (CCr) in the pre-pregnancy (Pre-P), first trimester (1T), third trimester (3T) and 1 year postpartum (PP) were evaluated. In both groups there were an increase in 3T compared to Pre-P of CCr (137 vs. 98 ml/min and 110 vs. 81 ml/min, p=0.0001, respectively) and UAE (7.78 vs. 3.15 mg/24 h and 592 vs. 119 mg/24 h, p=0.0001, respectively). Increase of Cr in the PP compared to 1T in Group II (0.88 vs. 0.70 mg/dL, p=0.031) was observed. There were no difference in UAE, CCr and Cr in the PP when compared to pre-P as well variance over time between groups. Group II showed higher prevalence of chronic hypertension (72.7 vs. 21.9%, p=0.004), preeclampsia (63.6 vs. 6.3%, p=0.0003) and lower gestational age at birth (36 vs. 38 weeks, p=0.003). We conclude that pregnancy was not associated with development and progression of diabetic nephropathy in women with or without mild renal dysfunction. The presence of diabetic nephropathy was associated with increased risk of perinatal complications.

Insuficiência renal aguda em pacientes com infecçäo pelo vírus da imunodeficiência humana (HIV) / Acute kidney failure in patients with human immunodeficiency virus infection

Estudamos a freqüência de insuficiência renal aguda (IRA) entre 240 pacientes internados com sintomas da infecçäo pelo HIV, encontrando 34 episódios em 33 pacientes (13,75). Sua freqüência foi maior nas crianças que nos demais pacientes da série (respectivamente, 34,4 por cento x 12,7 por cento, p < 0,05). O número de sobreviventes 1 mês após a instalaçäo da IRA foi baixo (5 casos, 15,2 por cento). Nenhum dos 21 doentes com quadro séptico associado sobreviveu por mais de 1 mês após o surgimento da IRA, enquanto 5 dos 12(41,7 por cento) näo sépticos ultrapassaram este período (p < 0,01), obtendo alta. Conclui-se que IRA foi importante causa de morbidade entre os pacientes com infecçäo pelo HIV, estando as crianças sob maior risco de desenvolvê-la. O prognóstico após a IRA é ruim, especialmente quando associada à sepsis
