Hypoadrenocorticism in a young dwarf cat--case report/ Hipoadrenokorticizam u patuljastog maceta--prikaz slucaja

A 8-month-old cat with immature appearance was referred as an emergency, showing lethargy, weakness, anorexia and dehydration. The case history reported two months of apparently neurologic disorders with behavioral changes and waxing-waning clinical course, including temporary remissions associated with parenteral fluid and/or corticosteroid administration. Clinical examination revealed hypovolemic shock, extreme weakness, severe hypothermia, and bradycardia. Laboratory profile revealed several abnormalities consistent with hypoadrenocorticism. After clinical stabilization, an adrenocorticotropic hormone (ACTH) stimulation test was performed, confirming the suspicion. The cat had a rapid decline and died. Probably, previous diagnostic errors and inappropriate treatments compromised the outcome of therapy. We emphasize the importance of early diagnosis in a disease that, although rare in this species, should not be overlooked in the differential diagnosis. Keywords: Addison's disease, feline, hypothermia weakness, low Na:K ratio, shock Osmomjesecno mace bilo je zaprimljeno kao hitan slucaj sa znakovima letargije, slabosti, anoreksije i dehidracije. U povijesti bolesti naznaceno je da su se neuroloski poremecaji javili prije dva mjeseca zajedno s poremecajima u ponasanju i ispadima bijesa s povremenim smirivanjem klinickih znakova nakon parenteralne primjene tekucine i/ili kortikosteroida. Klinickom pretragom ustanovljen je hipovolemijski sok, izrazita slabost, teska hipotermija i bradikardija. Laboratorijski je ustanovljeno nekoliko poremecaja karakteristicnih za hipoadrenokorticizam. Nakon klinicke stabilizacije, za povrdivanje sumnje bio je primijenjen test stimulacije adrenokortikotropnim hormonom (ACTH). Mace je naglo slabilo i uginulo. Prijasnje dijagnosticke pogreske i neodgovarajuce lijecenje vjerojatno su pogorsali ishod bolesti. Naglasava se vaznost rane dijagnostike bolesti, koju se, premda rijetku u macaka, ne bi smjelo previdjeti u diferencijalnoj dijagnostici.
