The 8-month-old patient was hospitalized after a few days of apathy and feeding difficulty with moderate exsiccation. Severe hypokalemia, hyponatremia, hypochloremia associated with alkalosis were found, which were accompanied by the decreased urinary electrolytes and elevated serum renin and aldosterone, therefore the condition corresponded to a pseudo-Bartter syndrome. The diagnosis of cystic fibrosis was arisen, which was established by the elevated sweat chloride levels. Sequencing of the 27 exons of the cystic transmembrane regulator gene two rare mutations were detected in compound heterozygous form: in the exon 10 a C1529G transversion, whereas in the exon 20 a G3978A transition was verified, both of them result in development of premature stopcodons (S466X and W1282X, respectively). Carriage of first mutation could be found in the asymptomatic mother, while the other one was identified in the father. In the proband and in the mother a G3341A mutation was also detected in exon 17, which causes an R1070Q amino acid change. However, this likely cannot associate with pathology since the existing premature stopcodon on the same allele does not allow synthesis of protein. These mutations have been described in combination with delta F508 mutation, however, their simultaneous presence in the same subject has not been reported. During the one and half year follow-up the clinical picture appeared benign.

Autosomal dominant polycystic kidney disease (ADPKD) is the most frequent life- threatening, hereditary disease. ADPKD is more common than sickle cell anemia, cystic fibrosis, muscular dystrophy, hemophilia, Down's syndrome, and Huntington's disease combined. ADPKD is a multisystemic disorder characterized by the progressive development of renal cysts and marked renal enlargement. Structural and functional renal deterioration occurs in ADPKD patients and is the fourth leading cause of end-stage renal disease (ESRD) in adults. Aside from the renal manifestations, extrarenal structural abnormalities, such as liver cysts, cardiovascular abnormalities, and intracranial aneurysms may lead to morbidity and mortality. Recent studies have identified prognostic factors for progressive renal impairment including gender, race, age, proteinuria, hematuria, hypertension and increased left ventricular mass index (LVMI). Early diagnosis and better understanding of the pathophysiology of the disease provides the opportunity to aggressivly treat hypertension with renin-angiotensin-aldosterone system inhibitors and thereby potentially reduce LVMI, prevent cardiovascular morbidity and mortality and slow progression of the renal disease.

There are many important respiratory manifestations of endocrine and metabolic diseases in children. Acute and chronic pulmonary infections are the most common respiratory abnormalities in patients with diabetes mellitus, although cardiogenic and non-cardiogenic pulmonary oedema are also possible. Pseudohypoaldosteronism type 1 may be indistinguishable from cystic fibrosis (CF) unless serum aldosterone, plasma renin activity, and urinary electrolytes are measured and mutation analysis rules out CF. Hypo- and hyperthyroidism may alter lung function and affect the central respiratory drive. The thyroid hormone plays an essential role in lung development, surfactant synthesis, and lung defence. Complications of hypoparathyroidism are largely due to hypocalcaemia. Laryngospasm can lead to stridor and airway obstruction. Ovarian tumours, benign or malignant, may present with unilateral or bilateral pleural effusions. Metabolic storage disorders, primarily as a consequence of lysosomal dysfunction from enzymatic deficiencies, constitute a diverse group of rare conditions that can have profound effects on the respiratory system.

Bronchial artery embolization is the recommended therapy for massive hemoptysis in patients with cystic fibrosis (CF). We report on two cases of multiple renal infarcts and renin-associated hypertension and hypokalemia occurring in CF adults after bronchial artery embolizations. These complications were presumably related to crossing of small calibrated microspheres through arteriovenous anastomoses. Although hypokalemia resolved rapidly, hypertension persisted at least 6 months and its control required multiple antihypertensive agents. Physicians should be aware of this potentially severe, but previously unreported, complication of bronchial artery embolization.
