Approach to Pregnancy in Patients With Lupus Nephritis.

Active lupus nephritis (LN) in pregnancy is strongly associated with poor maternal and fetal outcomes and, therefore, has implications on the planning, timing, and management. Prepregnancy evaluation is essential for all LN patients with childbearing potential to ensure pregnancies proceed in a safe and timely manner. Both maternal and fetal risks are communicated to patient during the evaluation. Stratification into different risk profile groups is then made based on disease activity and organ impairment severity. Patients with LN are generally divided into 3 main groups. Patients with LN who become pregnant receive treatments that are nonteratogenic and optimal for fetal and maternal outcomes. Throughout the pregnancy period, these patients are monitored closely under surveillance by a multidisciplinary team of clinicians. The management of patients with LN in pregnancy can be challenging both diagnostically (distinguishing LN from pre-eclampsia and determining the role and timing of kidney biopsy) and therapeutically (LN flares during pregnancy and managing a newly diagnosed LN during pregnancy).

Novel Therapeutics for Management of Lupus Nephritis: What Is Next?

Lupus nephritis is a severe, organ-threatening manifestation of systemic lupus erythematosus. The current standard of care in the treatment of lupus nephritis is limited to broad-spectrum immunosuppressants, which have significant concerns of short- and long-term toxicity. With traditional approaches, kidney survival and patient outcomes have remained suboptimal. Robust research in the therapeutics of lupus nephritis has resulted in development of many novel drugs targeting specific inflammatory response pathways. Some newer agents have shown a definitive signal of benefit when added to standard of care. With the advent of precision medicine in nephrology, lupus nephritis treatment may undergo a shift toward incorporating approaches using these newer drugs and individualizing care of our patients. This review highlights major advances in management of lupus nephritis over the last 25 years and explores the ongoing trials of emerging therapies in lupus nephritis.

Sodium-Glucose Cotransporter 2 Inhibitors and Urinary Tract Infection: Is There Room for Real Concern?

Sodium-glucose cotransporter 2 (SGLT2) inhibitors have revolutionized our armamentarium for kidney and heart protection in patients with or without diabetes. Based on early reports of a limited number of cases, a concern for increased risk of urinary tract infections arose, which has become one of the main areas of concern for some clinicians. However, data from large randomized clinical trials and real-world population-based studies have not shown a significantly increased risk of UTI in patients on SGLT2 inhibitors. The goal of this brief review article is to review the literature and provide reassurance to patients and prescribers for the broader use of these agents.

Serologic and urinary characteristics of laboratory-confirmed genitourinary tuberculosis at a tertiary hospital in the Philippines.

BACKGROUND: Genitourinary tuberculosis (GUTB) is known to cause high rates of structural organ damage, however, literature on its biochemical manifestations is limited. Additionally, local studies in the Philippine setting, where cases are rampant, are few and dated. This study aimed to determine the serologic and urinary profile of patients with GUTB admitted at a tertiary hospital within January 2009 to March 2020 and their association with short-term outcomes. METHODS: This retrospective study included 112 patients with laboratory-confirmed GUTB (i.e., positivity in acid-fast smear, polymerase chain reaction, culture, or histology). Demographic data, clinical characteristics, laboratory and radiologic findings, histopathology reports, treatment, and short-term outcomes were recorded. RESULTS: Bladder (54.5%) and kidney (36.4%) were the most affected organs. The male:female ratio was 1:1.15, and the mean age was 35.79 ± 18.29 years. Weakness (14.29%) was the most common chief complaint. A majority presented with anemia (83.04%), while several had leukocytosis (41.96%) and thrombocytosis (26.79%). Hypoalbuminemia (58.10%), impairment of renal function (36.94%), and electrolyte abnormalities such as hyponatremia (50.93%), hypercalcemia (20.19%), and hypokalemia (21.82%) were common. Proteinuria (67.96%) and pyuria (67.96%) were the most frequent abnormal findings, followed by hematuria (51.46%), acidic urine (45.63%) and low specific gravity (31.07%). Age, leukocytosis, and the need for pressors were all significantly associated with mortality (p values of <0.001, 0.010, and <0.001, respectively). CONCLUSIONS: The young age at presentation with severe clinical and laboratory manifestations may reflect local epidemiology as TB continues to be widespread in the country. Apart from the more commonly cited abnormalities in literature, multiple electrolyte imbalances and urinary concentration defects were also observed in many cases, possibly indicating tubulointerstitial involvement-a complication increasingly mentioned in case reports. As several patient characteristics were found to be associated with the high mortality rates observed in the study, further research is recommended to explore predictive modeling.

Crescentic postinfectious glomerulonephritis in an adult patient with juvenile nasopharyngeal angiofibroma.

Crescentic glomerulonephritis is usually associated with an acute nephritic syndrome with rapidly declining renal function. Postinfectious cases usually have a higher possibility of recovery. Juvenile nasopharyngeal angiofibroma (JNA) is a rare, locally aggressive tumour affecting mostly young men. A 28-year-old man presented with recurrent JNA initially excised 2 years prior. The patient was initially managed as a case of airway obstruction and pneumonia. He developed tea-coloured urine, oedema and acute kidney failure requiring dialysis while awaiting surgery. Urine and immunological studies (low C3, negative antineutrophil cytoplasmic antibody and antinucleosomal antibody and high antistreptolysin O) suggested a nephritic aetiology. Nasopharyngeal swab cultures of the mass revealed gram-negative organisms. Kidney biopsy showed diffuse proliferative glomerulonephritis compatible with a postinfectious glomerulonephritis with 77% cellular crescents. The mass was excised with histopathology consistent with JNA. The patient was eventually discharged off dialysis.

Clinical Characteristics and Short-Term Outcomes of Chronic Dialysis Patients Admitted for COVID-19 in Metro Manila, Philippines.

AIM: Data published on COVID-19 in the Filipino population, particularly those with end stage kidney disease (ESKD) are still lacking. METHODS: We performed a retrospective, observational study of 68 ESKD patients admitted with COVID-19 infection at a tertiary hospital in Metro Manila, Philippines from April 1, 2020 to July 31, 2020. We compared the clinical features, baseline laboratory data, treatment strategies and short-term outcomes between those who survived and those who died. We also determined the risk factors associated with mortality from COVID-19. RESULTS: Mean age was 54.5 years old, 66% were male. All patients admitted were on maintenance hemodialysis (HD). The most common presenting symptoms were dyspnea (57%), fever (47%) and cough (38%). There was an equal number of patients on high flow nasal cannula (17.7%) and invasive mechanical ventilation (17.7%). ICU admission was required in 17.7% of the cohort. In-hospital death occurred in 25% of the patients. Admission PaO2/FiO2 (PF) ratios (162 ± 134 versus 356 ± 181; p=0.0009) were lower, and procalcitonin (6.07 ± 10.5ng/mL versus 0.73 ± 3.61 ng/mL; p=0.02), lactate dehydrogenase (396 ± 274U/L versus 282 ± 148 U/L; p=0.03), and white blood cell counts (10 ± 7.3 x 109/L versus 6.3 ± 4.2 x 109/L; p= 0.0039) were significantly higher among those who died compared to those who survived. After adjusting for confounders, only low PF ratio (HR 1.01 for every unit decrease, 95% CI 1-1.01) and need for ventilation (HR 6.45, 95% CI 1.16-35.97) conferred a significant risk for in-hospital mortality. CONCLUSION: Short-term, in-hospital mortality is high among patients on chronic hemodialysis admitted for COVID-19 infection. They present similarly with the general population. Low PF ratio on admission and need for ventilation are independent risk factors for in-hospital mortality.

Muscle spasm-induced exothermia in dystonic cerebral palsy: uncommon and frequently misdiagnosed condition.

A known cerebral palsy young man presented with prolonged bouts of generalised body movements associated with high-grade fever without any localising signs of infection, requiring multiple hospital admissions over several months. All septic work-ups, including a lumbar puncture, were negative. Serum chemistry was consistent with rhabdomyolysis. Repeated electroencephalograms showed no epileptiform discharges. Cranial MRI with gadolinium contrast revealed left cerebral atrophy with hyperintensities at the left basal ganglia. Uncontrolled dystonia with concomitant rhabdomyolysis was considered. Subsequent aggressive hydration and administration of muscle relaxant afforded abrupt resolution of symptoms.
