A 39-yr-old male with hepatorenal syndrome type 1 and refractory ascites was treated with continuous renal replacement therapy (CRRT) resulting in clinical improvement. He was positive for antibodies to hepatitis B, C, and human immunodeficiency viruses, and had a history of chronic alcohol and iv drug abuse. The patient had 4 hospital admissions during a 12-wk period. He first presented with advanced liver disease including pedal edema and a serum ammonia level of 56 micromol/L (reference range: 11 - 35 micromol/L). In subsequent admissions, he had asterixis, nausea, vomiting, jaundice, and worsening pedal edema. On his 4th admission, there was lethargy, tense ascites, decreased urinary output, bilateral edema of the lower extremities and scrotum, serum creatinine of 6.2 mg/dl (reference range: 0.6 - 1.5 mg/dl), and weight gain of 16 kg during the prior 8 wk. During the first 3 hospitalizations, he was treated with lactulose with slight improvement. On the 4th admission, he was started on low-dose dopamine (3 microg/kg/min) and 25% salt-poor albumin without clinical improvement. A pulmonary artery catheter was placed and hemofiltration by CRRT was performed for 5 days, with removal of 26.7 L of fluid and a net reduction of 11 kg of body weight. Serum creatinine decreased to 4.2 mg/dl during CRRT and was 2.2 mg/dl at hospital discharge 2 weeks later. His PaO(2) improved from 66 to 78 mmHg and his systemic vascular resistance increased from 571 to 799 dyne.sec/cm(5). CRRT was effective in relieving severe fluid retention and producing marked clinical improvement. We suggest that CRRT should be considered for the treatment of refractory ascites including that caused by hepatorenal syndrome.

With the availability of better treatment and prophylactic regimens for the infectious complications of human immunodeficiency virus (HIV), the non-infectious complications are gaining greater attention. HIV-related pulmonary arterial hypertension (HIV-PAH) is one of these. The incidence of HIV-PAH is estimated at 0.5% of HIV-infected individuals. The pathogenesis remains unclear. Patients present with symptoms as diverse as progressive shortness of breath, pedal edema, dry cough, fatigue, syncope, as well as chest pain. Chest X-ray always shows cardiomegaly and prominent pulmonary artery, and evidence of right ventricular hypertrophy can be seen from the electrocardiogram. The pulmonary arterial systolic pressure, diastolic pressure and pulmonary vascular resistance from right heart catheterization are increased. There are a few small studies showing the benefit of prostacyclin analog (epoprostenol and iloprost) and bosentan. The role of antiretrovirals remains controversial, as do those of other agents such as calcium channel blockers and anticoagulants. The prognosis of HIV-PAH is grave. Two thirds of HIV-PAH related mortality is usually secondary to consequences of pulmonary hypertension, with the worst survival noted in New York Heart Association (NYHA) functional class III-IV. The probability of survival in one series was 73%, 60% and 47% at one, two and three years, respectively.

An adolescent boy presented to pediatrics outpatient department with complaints of recurrent diarrhea, nausea, vomiting, and pedal edema since 3-4 months, with no relief even after taking treatment. His investigation revealed decreased serum IgA, IgG, and IgM levels with hypoproteinemia. Duodenal biopsy showed features of celiac disease (CD), but tissue transglutaminase IgA was negative. In stool examination, plenty of Giardia lamblia cysts and eggs of Hymenolepis nana were present. He improved on treatment and remained asymptomatic for 4 months. However, he again developed symptoms and succumbed to his illness. In patients of common variable immunodeficiency (CVID), who present with features of CD, coinfection, especially with G. lamblia and other parasites must always be kept in mind. The aim is to report a case of recurrent giardiasis with CVID mimicking CD from Western Rajasthan, India.

Membranous nephropathy (MN) associated with malignancies is a well-known entity. However, its association with benign neoplasm is not broadly recognized. A 69-year-old man with recurrent nephrotic syndrome presented with pedal edema and proteinuria of 5 months' duration. Laboratory results showed hypoalbuminemia and hyperlipidemia. Proteinuria was estimated to be protein excretion of 3.5g/d. Studies were negative for viral hepatitis, syphilis, human immunodeficiency virus, autoimmune diseases, and paraproteinemia. Kidney biopsy disclosed MN with negative phospholipase A2 receptor (PLA2R) staining, favoring a secondary form of MN. Computed tomography detected a 7.6-cm duodenal schwannoma. Elective surgical resection was performed. Pathologic study showed that THSD7A (thrombospondin type 1 domain-containing 7A) was positive in both glomeruli and schwannoma. Commonly, secondary MN is related to underlying conditions, including lupus, hepatitis, and neoplasm, and can be medication induced. The risk for developing a concomitant neoplasm among patients with PLA2R-negative MN is up to 12 times higher than in the general population. Most of these neoplasms are malignancies, and the presence of autoantibodies directed at similar tissue targets is hypothesized as the potential mechanism. In our case, THSD7A may be the autoantibody that has linked the schwannoma and the development of MN. Although benign tumors rarely produce renal manifestations, effective treatment may lead to resolution of nephrotic syndrome.
