RESUMO

BACKGROUND: C-reactive protein (CRP) is an inflammatory protein used in clinical practice to identify and monitor inflammatory and infectious processes. Recent data suggest CRP might be useful in guiding antibiotic therapy discontinuation among critical care patients. This meta-analysis analyzed the benefits and risks of CRP-guided protocols to guide antibiotic therapy in hospitalized patients in comparison with standard treatment. METHODS: Studies were searched in four databases: CENTRAL, Medline, Embase and LILACS. The search was performed until Jan 25th, 2023. The reference lists of the articles retrieved and related review studies were hand-screened to find eligible trials that might have been missed. Primary endpoints included the duration of antibiotic therapy for the index episode of infection. The secondary endpoint was the all-cause hospital mortality and infection relapses. The risk of bias was evaluated using the Cochrane Risk of Bias 2.0 tool. Random effects were used to pool the mean differences and odds ratio of individual studies. The protocol was registered in PROSPERO (CRD42021259977). RESULTS: The search strategy retrieved 5209 titles, out of which three studies met the eligibility criteria and were included in this meta-analysis. 727 adult patients were analyzed, of whom 278 were included in the intervention group and 449 were included in the control group. 55,7% of all patients were women. Meta-analysis indicated that experimental groups (CRP-guided) had a lower duration of antibiotic therapy (days) [MMD = -1.82, 95%IC -3.23; -0.40]; with no difference in mortality [OR = 1.19 95%IC 0.67-2.12] or in the occurrence of infection relapse [OR = 3.21 95%IC 0.85-12.05]. CONCLUSION: The use of CRP-guided protocol reduces the total amount of time required for antibiotic therapy when compared to standard protocols of treatment in hospitalized patients with acute bacterial infection. We did not observe statistical differences regarding mortality and infection relapse rates.

RESUMO

BACKGROUND: Losing-salt tubulopathies, such as Bartter syndrome, are rare and usually inherited due to mutations of tubular reabsorption channels of the nephrons. Despite its scarcity, some cases of acquired losing-salt tubulopathies have been described. In this case report, we discuss the main aspects of Bartter syndrome and present a rare pediatric case of probable tacrolimusinduced Bartter-like syndrome in a renal transplanted boy. CASE PRESENTATION: A ten-year-old male patient with end-stage renal disease due to endo and extra capillary glomerulonephritis was submitted to renal transplantation from a deceased donor. The post-operatory evolution was satisfactory with normalization of serum creatinine levels, mild hypertension, and the absence of metabolic disorders. The immunosuppression protocol included tacrolimus (0.3 mg/kg/day), mycophenolate (455 mg/m2/day) and prednisone (0.5 mg/kg/day). Two months later, the patient was hospitalized due to vomiting, dehydration, intense hypokalemia (1.3 mEq/L), hyponatremia (125 mEq/L), and hypochloremia (84 mmol/L). During hospitalization, he evolved with polydipsia (3000 mL/day) and polyuria (120-160 mL/m2/h) associated with major elevation of urinary potassium excretion, hypercalciuria, mild metabolic alkalosis, hyperfiltration, and proteinuria. The tacrolimus dose was reduced under the suspicion of tubular dysfunction, leading to a better metabolic profile. However, the patient developed a Banff IIb graft rejection, which required pulse therapy and elevation of tacrolimus and mycophenolate doses. Recovery of renal function parameters occurred, but the metabolic disorders worsened following tacrolimus dose elevation. The patient required chronic potassium, chloride, and sodium replacement. CONCLUSION: After administering immunosuppressive medications, physicians should be aware of the possibility of Bartter-like or other losing-salt tubulopathies syndromes that can affect metabolic homeostasis. The suspicion must always be considered in the case of a transplanted patient who presents dehydration and hydroelectrolytic disorders right after the commencement of nephrotoxic immunosuppressive drugs, including tacrolimus and cyclosporine.

RESUMO

A 75-year-old man was hospitalised for bronchoscopy with biopsy due to a suspicious pulmonary mass at chest tomography. He had significant dyspnoea, constipation, nausea, vomiting, anorexia and a 33% loss of weight in the past 3 months. Biopsy revealed a pulmonary squamous cell carcinoma, which was inoperable. Tramadol used at home for 3 months was replaced by morphine on admission. The patient remained constipated despite prokinetics and laxatives, leading to the diagnostic hypothesis of paraneoplastic motility disorder and opioid-induced constipation. Abdominal tomography ruled out the possibility of mechanical obstruction. As complications, the patient presented superior vena cava syndrome and opioid (morphine) intoxication. The patient died a few days later. The management of this case highlights the importance of multidisciplinary care and the challenges of palliative oncology care. Paraneoplastic motility disorder must always be considered among the mechanisms of intestinal dysfunction in patients with advanced oncological disease.

RESUMO

Abstract Involvement of the kidneys by lupus nephritis (LN) is one of the most severe clinical manifestations seen in individuals with systemic lupus erythematosus (SLE). LN is more frequent and severe in pediatric patients and has been associated with higher morbidity and mortality rates. This narrative review aimed to describe the general aspects of LN and its particularities when affecting children and adolescents, while focusing on the disease's etiopathogenesis, clinical manifestations, renal tissue alterations, and treatment options.


Resumo A nefrite lúpica (NL) é caracterizada pelo acometimento dos rins no contexto das diversas manifestações clínicas do Lupus Eritematoso Sistêmico (LES), e representa uma das manifestações clínicas mais graves da doença. A NL é mais frequente e mais grave nos pacientes pediátricos, em comparação com os adultos, e causa maiores taxas de morbidade e mortalidade. O objetivo desta revisão narrativa foi descrever os aspectos gerais da NL e suas particularidades em crianças e adolescentes, com foco em sua etiopatogênese, nas manifestações clínicas, nas alterações histopatológicas renais e na abordagem terapêutica.
