A state of biochemical hypothyroidism is commonly seen in infants with congenital nephrotic syndrome (NS) and therefore the current recommendation is to place all patients with congenital NS on supplemental thyroid preparations. We report our experience in five children with congenital NS in whom thyroid supplementation was discontinued following bilateral nephrectomy and initiation of renal replacement therapy. Immediately after nephrectomy, thyroid function tests normalized, except serum thyroid-stimulating hormone (TSH) concentration, which initially rose, but normalized later. This observation supports the hypothesis that hypothyroidism in these patients is secondary to the chronic massive proteinuria and is not the result of a defect intrinsic to the thyroid gland itself. Abatement of massive proteinuria enables discontinuation of thyroid supplementation, and a transient rise in TSH in the early post-nephrectomy stage should be potentially expected.

A 57-year-old woman was diagnosed in January 1982 with SLE based on ANA 1:640, positive LE cell preparation, proteinuria (3+), and pericarditis. In 1984, 1994, and 1997, the pericardial effusion was noted to have increased without signs of disease exacerbation or cardiac tamponade, and pericardial drainage was repeated to control the effusion. A massive pericardial effusion developed in August 1997. After tuberculosis, hypothyroidism, neoplasm, and progression of SLE were ruled out, we decided to perform pericardial fenestration. A safe and minimally invasive pericardial fenestration was successfully completed endoscopically. Pathologic study of the specimen revealed chronic pericarditis. We consider endoscopic pericardial fenestration to be useful for at risk patients with pericarditis to control the effusion and establish a differential diagnosis.

Infestation with a short-tailed demodectic mite and Demodex canis was diagnosed in both a six-and-a-half-year-old and a four-year-old dog. The clinical picture was compatible with generalised demodicosis complicated by staphylococcal pyoderma (case 1), or localised demodicosis (case 2). In both cases, the short-tailed demodectic mite outnumbered D canis in superficial skin scrapings. The laboratory findings (lymphopenia, eosinopenia, increased serum alkaline phosphatase and alanine aminotransferase activities, diluted urine and proteinuria) and the results of a low dose dexamethasone suppression test were suggestive of underlying hyperadrenocorticism in the first case. Hypothyroidism was considered a possibility in the second case, owing to the sustained bradycardia and the extremely low basal total thyroxine value. Systemic treatment with ivermectin and cephalexin (case 1), or topical application of an amitraz solution in mineral oil, along with sodium levothyroxine replacement therapy (case 2), resulted in a complete resolution of the skin lesions and the disappearance of both types of demodectic mite after two and one and a half months, respectively.

We report two patients in whom hypothyroidism was considered to cause renal dysfunction. Case 1 was a 65-year-old woman who stopped taking levothyroxine sodium for hypothyroidism. After 6 months, she developed proteinuria, edema, weight gain, and renal dysfunction. Renal biopsy revealed focal segmental proliferative glomerulonephritis. After re-administration of levothyroxine sodium, thyroid function and renal function both recovered. Case 2 was a 51-year-old man who presented with edema, difficulty in swallowing, muscular weakness, and fatigue. We diagnosed hypothyroidism, and focal segmental proliferative glomerulonephritis was revealed by renal biopsy. After administration of levothyroxine sodium, his symptoms resolved and his thyroid function and renal function both improved. Our experience suggests that hypothyroidism should be taken into consideration as one of the causes of renal dysfunction.

Panhypopituitarism manifests various symptoms including growth failure, hypothyroidism, adrenal insufficiency and hypogonadism. Dwarfism is an important problem in children with this condition, and long-term treatment with recombinant human growth hormone (GH) is usually required. We report a 24-year-old man with panhypopituitarism complicated by focal segmental glomerulosclerosis (FSGS). The patient had been treated with GH for hypopituitary dwarfism from 3 years of age. Proteinuria was initially noticed at 15 years of age and persisted despite cessation of GH supplementation at 18 years of age. A renal biopsy specimen showed glomerular hypertrophy and limited glomerulosclerosis, compatible with FSGS. To our knowledge, this is the first reported case of panhypopituitarism complicated by FSGS. Our case suggests that GH treatment for dwarfism may induce irreversible glomerular disease.

The purpose of this study was to summarize the clinical findings in 40 dogs with systemic hypersensitivity reactions associated with the administration of potentiated sulfonamides. Dogs ranged from 6 months to 14 years of age, with a mean of 5.7 +/- 3.2 years. Spayed female dogs were overrepresented (24 of 40, or 60% of the dogs), as were Samoyeds (3 of 40; 8%) and Miniature Schnauzers (5 of 40; 13%). Mean dosages of potentiated sulfonamides were 47.0 +/- 14.9 mg/kg/d (range, 23.4-81.4 mg/kg/d). The time from the 1st administration of the drug to the onset of the clinical signs of hypersensitivity ranged from 5 to 36 days, with a mean of 12.1 +/- 5.9 days. There was no relationship between either the dosage or type of sulfonamide given and the time to the onset of the clinical signs. Fever was the most common clinical sign observed (55% of the dogs); thrombocytopenia was 2nd (54%), and hepatopathy (28%) was 3rd. Neutropenia, keratoconjunctivitis sicca (KCS), hemolytic anemia. arthropathy, uveitis, skin and mucocutaneous lesions, proteinuria, facial palsy, suspected meningitis, hypothyroidism, pancreatitis, facial edema, and pneumonitis were also observed in some patients. Of 39 dogs with adequate follow-up, 30 (77%) recovered, whereas 8 (21%) either died or were euthanized, and 1 recovered clinically but had persistent increases in alanine aminotransferase (ALT) activity. Dogs with hepatopathy generally had a poorer prognosis (46% recovery) than dogs without hepatopathy (89% recovery; P = .0035). Sixty-three percent of the dogs with thrombocytopenia recovered, compared to 90% of the dogs without thrombocytopenia (P = .042). Recovery was not associated with sex, age, breed, or type of sulfonamide administered.

Hashimoto's thyroiditis and membranous nephropathy are believed to be mediated by immune mechanisms. A 12 year-old patient is reported who presented with fatigue, dislike of cold, pallor and growth retardation. Initial laboratory assessment showed moderate proteinuria and impaired renal function (serum creatinine 2.3 mg/dl), and hypothyroidism due to autoimmune thyroiditis. Light, immunofluorescence and electron microscopy of the renal biopsy showed membranous nephropathy. The patient recovered from nephropathy after substitution of thyroid hormone and therapy with prednisone. Megalin can be envisaged as a potential pathogenetic link between the two disease entities. The glycoprotein megalin is expressed on thyroid cells in a TSH-dependent manner and may have a crucial role in the immunopathogenesis of glomerular injury in membranous nephropathy. For similar cases, we want to encourage colleagues to consider this hypothesis and to examine blood and renal biopsy specimens for the presence of megalin and antibodies against it.

We present four adult cases of acute renal failure associated with hypothyroidism. All patients presented with symptoms suggestive of moderate to severe hypothyroidism, such as cold intolerance, constipation, muscle weakness, and lower extremity oedema. Initial serum creatinine levels ranged between 115 and 203 micromol/L (1.3 and 2.3 mg/dL), with creatinine clearances (CrCl) ranging between 0.58 and 0.97 mL/s (34.5 and 58 mL/min). After 6-12 weeks of treatment with levothyroxin, serum creatinine levels decreased to the range of 80 and 124 micromol/L (0.9 and 1.4 mg/dL) and CrCl increased to 0.74-1.64 mL/s (44-98 mL/min). One patient had proteinuria of 800 mg/day, which decreased to the normal range (<200 mg/day) after levothyroxin treatment. One patient developed acute gouty arthritis before normalization of thyroid-stimulating hormone (TSH), which was successfully managed with prednisone therapy. All of our patients had increased creatine kinase (CK), ranging between 1000 and 2360 U/L (normal range, 22-165 U/L), which normalized after 6 weeks of levothyroxin treatment.

Several cases of glomerular disease have been associated to thyroid diseases. The most frequent lesion described is membranous glomerulopathy, presented as a nephrotic syndrome. Here we report a 67-year-old man who developed a nephrotic syndrome accompanied by rapid derangement of renal function shortly after the onset of a primary hypothyroidism due to autoimmune thyroiditis. High titers of circulating anti-thyroglobulin and anti-microsomal thyroid antigen antibodies were detected. Serum levels of C3 and C4 fractions of complement were markedly decreased. Renal biopsy showed a membranoproliferative glomerulonephritis with severe mesangial proliferation, a type of glomerular involvement non-described previously in the literature, in relation with thyroid diseases. Four boluses of intravenous steroids were administered, followed by oral prednisone for three months. A dramatic recovery of renal function, together with normalization of urinary sediment, proteinuria decrease and normalization of serum complement were observed. Three years later, the patient suffered from a similar event, with a positive response to steroids again. One year later, the patient had a new recurrence and was treated with mycophenolate mofetil , improving his clinical situation.

POEMS syndrome is a rare plasma cell dyscrasia which is characterized by small amounts of monoclonal protein, and a multisystem complex manifested by various combinations of polyneuropathy, organomegaly, endocrinopathy and skin changes. Here, we presented an atypical case of POEMS syndrome with IgG kappa monoclonal protein, chronic demyelinating polyneuropathy, hepatosplenomegaly, hypothyroidism, gynecomastia and severe renal impairment. The finding of IgG kappa type of monoclonal protein in our patient was interesting because the majority of cases were reported to have lambda light chain. Also, the absence of typical skin and bone lesions were atypical. Though speculative, these atypical features may account for the unusual presentation of this case. Our patient rapidly progressed to end-stage renal failure and died of cachexia. Renal involvement in POEMS syndrome is rare but may show substantial clinical and pathological variations. Proteinuria, hematuria, renal dysfunction and renal failure requiring hemodialysis can be seen. The pathogenesis of renal dysfunction is unclear. As a conclusion, POEMS syndrome may present with diverse clinicopathologic manifestations. In this syndrome, renal involvement may lead to end stage renal failure and the course may be fatal due to severe polyneuropathy and wasting.
