Two children who presented with severe failure to thrive were found to have Type III glycogen storage disease. They both also had defects of tubular acidification, an association not previously described. The nature of the tubular lesion is characterized and the explanation and therapeutic implications are discussed.

Discussed here is a 41 year old woman with galactorrhea associated with the empty sella syndrome and mild renal tubular acidosis. Basal serum prolactin (PRL) levels were normal, but a 24 hour serum PRL secretory profile demonstrated an increased mean PRL concentration. Serum PRL was appropriately suppressed by the administration of L-dopa; however, chlorpromazine stimulation resulted in a blunted serum PRL response. Pituitary luteinizing hormone, follicle stimulating hormone, ACTH and thyroid stimulating hormone levels were normal. Thus, galactorrhea associated with an enlarged sella does not establish the diagnosis of a pituitary tumor, and pneumoencephalography must be performed to exclude the empty sella syndrome.
The diagnosis of transient renal tubular acidosis was made in a 16 months old boy. Bicarbonate titration studies revealed that the acidification defect consisted of an association of proximal and distal tubular acidosis. The effect of experimentally induced potassium depletion revealed that hyperkalemia contributed to the acidification defect. After correction of the acidification disorder a defect in urinary concentration was still present.

BACKGROUND: Neither the prevalence nor the associated risk factors of late post-transplant renal tubular acidosis (RTA) are known. METHODS: We conducted a cross-sectional study with 576 patients for more than 12 months after kidney transplantation, and a glomerular filtration rate (GFR) >40 ml/min. RTA was diagnosed by measurement of the urine anionic gap, urine pH and plasma potassium during acidosis, and fractional bicarbonate excretion after bicarbonate loading. Uni- and multi-variable analysis were used to isolate factors associated with post-transplant RTA, and with the different RTA subtypes. RESULTS: All patients (n = 76) had distal post-transplant RTA. A significant association with the presence of RTA was found for the intake of tacrolimus or renin-angiotensin-aldosterone blockers, the Parathyroid hormone level and the GFR. Type Ia (classic, distal), type Ib (hyperkalaemic, voltage-dependent), rate-limited and type IV RTA were present in 37, 14, 21 and 28% of the patients. Acute transplant rejection was the only significant different parameter between the RTA subtypes and more often present in patients with type Ia or Ib RTA. CONCLUSIONS: We conclude that a significant fraction of stable long-term renal transplant recipients with adequate graft function develop post-transplant RTA, with a preponderance for type Ia and type IV, and absence of type II. In addition, acute transplant rejection seems to have an influence on the subtype of RTA present post-transplantation.
