Pulmonary Renal Syndrome

Background. Pulmonary-renal syndrome is characterised by acute kidney injury, haematuria, and haemoptysis and is a well-recognised presentation of diseases such as ANCA vasculitis that require urgent immunosuppression. Case Presentation. A patient presented with a brief history of haemoptysis, acute renal failure, microscopic haematuria, and severe hypertension. The diagnosis was initially not clear so he was treated with antihypertensives, renal replacement therapy, and immunosuppression. Renal biopsy subsequently showed evidence of malignant hypertension. Autoantibodies were uniformly negative. Conclusions. This case demonstrates that malignant hypertension can present as pulmonary-renal syndrome.

Introduction: At present, we are witnessing an increase in preeclampsia, especially the most severe forms, which are associated with an increased risk of maternal-perinatal morbidity and mortality. As a severity criterion, acute kidney injury (AKI) has been associated with a worse prognosis, and for this reason, the maternal and perinatal variables associated with AKI in patients with severe preeclampsia (SP) were analysed in this study. Methods: An observational, retrospective, single-centre study of patients with SP treated at a tertiary hospital between January 2007 and December 2018 was conducted. The case criteria based on the criteria established by the ACOG Practice Guidelines for Gestational Hypertension and Preeclampsia. AKI is considered when serum creatinine exceeds 1.1 mg/dL in a pregnant woman with previously normal renal function. In patients with existing chronic kidney disease (CKD), it is referred to as AKI if the baseline serum creatinine increases by 1.5 fold. Pregestational, gestational and postpartum variables were analysed up to 12 weeks postpartum using univariate and multivariate logistic regression analysis. Results: During the study period, 76,828 births were attended, and 303 pregnant women were diagnosed with SP. The annual incidence of SP increased gradually throughout the study period, reaching 1.79/100 births/year in 2018. Acute kidney injury (AKI) occurred in 24.8% of the patients. The multivariate analysis revealed an increased association with a history of previous CKD, the use of assisted reproductive techniques and caesarean section. Uric acid and thrombotic microangiopathy (TMA) had a high correlation with AKI. Indications for caesarean section are associated with AKI in SP. Regarding perinatal outcomes in cases of AKI, there was a higher percentage of neonates who required foetal lung maturation with steroids and an increased need for NICU admission. No case of maternal death was recorded; however, an increase in neonatal mortality was found among patients who did not develop AKI. After 12 weeks postpartum, 72 patients were referred to the nephrology consultation for persistent hypertension, proteinuria or renal failure. Conclusions: In preeclampsia, AKI is a common complication, especially among patients with a history of CKD, those who became pregnant using assisted reproduction techniques and those who delivered via caesarean section. The perinatal impact of AKI is mainly centred on a higher rate of NICU admission and a lower mortality rate. Among biochemical and haematological markers, the uric acid level prior to renal failure has a direct and significant correlation with the risk of AKI, as does the development of TMA in patients with preeclampsia. Therefore, the monitoring of renal function in cases of preeclampsia should be strict, and referral for a nephrology consultation may be necessary in some cases.

Microangiopathic hemolytic anemia (MAHA), thrombocytopenia, fever, renal failure, and neurologic symptoms comprise the cardinal features of thrombotic thrombocytopenic purpura and hemolytic uremic syndrome. Etiologies can include medications, infections, cancers, or transplantation. We present a patient with a history of rectal cancer treated with mitomycin-C who developed MAHA, acute kidney injury, and thrombocytopenia 6 months after completing therapy and to did not respond the plasmapheresis or steroids. She was treated with four weekly doses of rituximab with full recovery.

Abstract The atypical hemolytic uremic syndrome (aHUS) is characterized by thrombocytopenia, microangiopathic hemolytic anemia and acute kidney injury (AKI), which can exhibit a poor prognosis. Complement factor H (CFH) gene mutations play a key role in this disease, which may be sporadic or familial. We studied 13 people from the same family, investigated for gene mutations of the familial aHUS after a family member presented to our emergency clinic with the aHUS and reported a family history of chronic renal failure. The p.S1191L mutation on the CFH gene was heterozygous in six people from the patient’s family with the aHUS. One of these family members is our patient with acute kidney injury, and the other two are followed at the Nephrology Clinic, Medeniyat University, Goztepe Training and Research Hospital, Istanbul, Turkey, due to chronic renal failure. The other three family members showed no evidence of renal failure. The index case had a history of six sibling deaths; three died of chronic renal failure. Plasmapheresis and fresh frozen plasma treatment were administered to our patient. When the patient showed no response to this treatment, eculizumab (ECZ) therapy was started. The study demonstrated that thorough family history should be taken in patients with the aHUS. These patients may have the familial type of the disease, and they should be screened genetically. Eculizumab should be the first choice in the treatment with plasmapheresis. It should be kept in mind that the use of ECZ as prophylaxis in posttransplant therapy is extremely important for preventing rejection.

Common Cause

Introduction: In the elderly, impairment of kidney function occurs. Renal diseases overlap with anatomic and functional changes related to age-related involutionary processes. Mortality among patients with acute renal injury is approximately 50%, despite advances in treatment and diagnosis of AKI. The aim: To assess the incidence of acute kidney injury in elderly patients and to analyze the causes of acute renal failure depending on age. Materials and methods: A retrospective analysis included medical documentation of patients hospitalized in the Nephrology Clinic during the 6-month period. During this period 452 patients were hospitalized in the clinic. A group of 77 patients with acute renal failure as a reason for hospitalization was included in the study. Results: The prerenal form was the most common cause of AKI in both age groups. In both age groups, the most common cause was dehydration; in the group of patients up to 65 years of age, dehydration was 29.17%; in the group of people over 65 years - 43.39%. Renal replacement therapy in patients with AKI was used in 14.29% of patients. In the group of patients up to 65 years of age hemodialysis was 16.67% and above 65 years of age. -13.21% of patients. The average creatinine level in the group of younger patients at admission was 5.16 ± 3.71 mg / dl, in the group of older patients 3.14 ± 1.63 mg / dl. The size of glomerular filtration GFR in the group of younger patients at admission was 21.14 ± 19.54 ml / min, in the group of older patients 23.34 ± 13.33 ml / min. Conclusions: The main cause of acute kidney injury regardless of the age group was dehydration. Due to the high percentage of AKI in the elderly, this group requires more preventive action, not only in the hospital but also at home.

A 42-year-old woman presented with chronic fever, abdominal pain, intermittent loose stools and dysuria for 3 months. She had recently developed acute dyspnoea with acute kidney injury. She was found to have a contracted, thick-walled bladder with bilateral hydroureteronephrosis. She underwent bilateral percutaneous nephrostomies, following which her renal function recovered. She satisfied the clinical and immunological features of the Systemic Lupus International Collaborating Clinics criteria for systemic lupus erythematosus (SLE). She was initiated on immunosuppression. Lupus cystitis with a contracted bladder is an uncommon presentation of SLE.

A 77-year-old man was admitted with severe acute kidney injury and nephrotic syndrome. He was started on eltrombopag for chronic idiopathic thrombocytopenic purpura 6 weeks earlier. An ultrasound of the kidneys was normal and an auto-antibody screen was negative. The use of the Naranjo adverse drug reaction probability scale indicated a probable relationship (score of 5) between the patient’s development of acute renal failure and eltrombopag therapy. Literature review identified only one other case of nephrotic syndrome and acute kidney injury associated with eltrombopag therapy in which a kidney biopsy revealed focal segmental glomerulosclerosis. Due to the challenges faced during the prevailing SARS-CoV-2 pandemic and persistent low platelet counts a renal biopsy was not undertaken. On stopping eltrombopag, the patients renal function stabilised and he successfully went into remission following treatment with high dose corticosteroids and diuretics. This report of a serious case of reversible renal failure and nephrotic syndrome after treatment with eltrombopag may serve to inform clinicians about the possible severe renal adverse effects of eltrombopag before its commencement for future use.

Acute kidney injury (AKI) is under-recognised in children and neonates. It is associated with increased mortality and morbidity along with an increased incidence of chronic kidney disease in adulthood. It is important that paediatricians are able to recognise AKI quickly, enabling prompt treatment of reversible causes. In this article, we demonstrate an approach to recognising paediatric AKI, cessation of nephrotoxic medication, appropriate investigations and the importance of accurately assessing fluid status. The mainstay of treatment is attempting to mimic the kidneys ability to provide electrolyte and fluid homeostasis; this requires close observation and careful fluid management. We discuss referral to paediatric nephrology and the importance of long-term follow-up. We present an approach to AKI through case-presentation.

Internal Hydrocephalus

A young farmer, tenth standard student, helping his grandfather during holiday, developed anuria after viper bite. Because of headache, non-enhanced CT scan head was done on admission which showed a small pituitary haemorrhage with normal ventricles. Later, he had generalized fits and second non-enhanced CT scan head was repeated which revealed a small pituitary haemorrhage with dilated ventricles. He also had acute kidney injury, septicaemia, cellulitis and DIC. The serum level of TSH, free T3 & free T4 were low; thus, replacement was done. Cerebrospinal fluid study (protein, sugar, cells) including culture was normal. Renal replacement therapy (haemodialysis), platelets transfusion and antibiotics were given. He had torrential polyuria (urine output 12 liter per day) when he recovered from renal failure and it improved dramatically with desmopressin replacement. There was improvement in third non-enhanced CT scan head and fourth one was consistent with normal ventricle and reduction in size of pituitary haemorrhage.
