Rare Disease Day 2019

rare disease day

 

Each and every day since 1987,  I tell anyone who will listen about Cushing’s.  I pass out a LOT Cushing’s business cards. My husband also passes out cards and brochures.

Adding to websites, blogs and more which I have maintained continuously since 2000 – at mostly my own expense.

Posting on the Cushing’s Help message boards about Rare Disease Day.  I post there most every day.

Tweeting/retweeting info about Cushing’s and Rare Disease Day today.

Adding info to one of my blogs about Cushing’s and Rare Disease Day.

Adding new and Golden Oldies bios to another blog, again most every day.

Thinking about getting the next Cushing’s Awareness Blogging Challenge set up for April…and will anyone else participate?

And updating https://www.facebook.com/CushingsInfo with a bunch of info today (and every day!)

~~~

Today is Rare Disease Day.

I had Cushing’s Disease due to a pituitary tumor. I was told to diet, told to take antidepressants and told that it was all my fault that I was so fat. My pituitary surgery in 1987 was a “success” but I still deal with the aftereffects of Cushing’s and of the surgery itself.

I also had another Rare Disease – Kidney Cancer, rare in younger, non-smoking women.

And then, there’s the secondary adrenal insufficiency…and growth hormone deficiency

Patient Develops Cyclic Cushing’s Syndrome Due to Lung Neuroendocrine Tumor

Tumors located outside the pituitary gland that produce the adrenocorticotropic hormone (ACTH) may cause, on rare occasions, cyclic Cushing’s syndrome — when cortisol levels show substantial fluctuations over time.

That finding, based on the case of a patient with ACTH-secreting lung cancer,  is found in the study, “Cyclic Cushing’s syndrome caused by neuroendocrine tumor: a case report,” which was published in Endocrine Journal.

Cushing’s syndrome is characterized by too much cortisol, either due to adrenal tumors that produce cortisol in excess, or because too much ACTH in circulation — resulting from ACTH-producing tumors — act on the adrenal glands to synthesize cortisol.

Cyclic Cushing’s syndrome (CCS) is a rare type of Cushing’s in which cortisol production is not steadily increased. Instead, it cyclically fluctuates, from periods with excessive cortisol production interspersed with periods of normal levels.

The fluctuations in cortisol levels over time pose difficulties for a definite diagnosis. Moreover, the precise mechanism underlying the periodic peaks of cortisol peaks are unknown.

Investigators now reported the case of a 37-year-old man admitted to the hospital due to repeated attacks of dizziness, weakness, and high cortisol levels for two weeks.

Repeated tests measuring the levels of cortisol in the blood and a 24-hour urine free cortisol (24 hUFC) assay confirmed a cyclic fluctuation of cortisol, with levels peaking three times and dropping twice (the standard rule for diagnosing CSC).

Upon hospitalization, he further developed high blood pressure and weight gain.

The patient underwent computed tomography (CT) scans, which revealed the presence of an ACTH-secreting tumor in the lungs, the likely cause of the patient’s Cushing’s symptoms. These type of tumors are called neuroendocrine tumors because they are able to release hormones into the blood in response to signals from the nervous system.

Additional scans detected tumors in the adrenal and pituitary glands, but further analysis revealed they were non-functioning tumors, i.e., as their name indicates, they didn’t release excessive ACTH. The thyroid gland also was positive for a tumor.

The patient underwent resection surgery to remove the tumor located in the lungs and nearby lymph nodes. After the surgery, the levels of cortisol in the blood and urine returned to normal, confirming the tumor as the source of the CSC.

The patient also received surgery to remove his thyroid tumor.

An analysis of the patient’s genomic DNA revealed a novel mutation in the PDE11A gene, which is linked to a rare form of ACTH-independent Cushing’s syndrome called primary pigmented nodular adrenocortical disease (PPNAD) type 2.

Whether the patient developed PPNAD, however, and the contribution of a potential PPNAD diagnosis to the CCS, requires further investigation. “To explore pathogenicity of the genetic mutation, we will still plan for a follow-up visit to this patient,” researchers wrote.

Rare Prostate Cancer Associated with Cushing’s Syndrome

A patient with depression developed Cushing’s syndrome (CS) because of a rare ACTH-secreting small cell cancer of the prostate, a case study reports.

The case report, “An unusual cause of depression in an older man: Cushing’s syndrome resulting from metastatic small cell cancer of the prostate,” was published in the “Lesson of the Month” section of Clinical Medicine.

Ectopic CS is a condition caused by an adrenocorticotropic hormone (ACTH)-secreting tumor outside the pituitary or adrenal glands. The excess ACTH then acts on the adrenal glands, causing them to produce too much cortisol.

Small cell cancer is more common in older men, those in their 60s or 70s. Sources of ectopic ACTH synthesis arising in the pelvis are rare; nonetheless, ACTH overproduction has been linked to tumors in the gonads and genitourinary organs, including the prostate.

Still, evidence suggests there are less than 30 published cases reporting ectopic CS caused by prostate cancer.

Researchers from the Southern Adelaide Local Health Network and the Royal Adelaide Hospital in Australia described the case of an 84-year-old man who complained of fatigue, back pain, and lack of appetite.

Blood tests revealed mildly elevated prostate-specific antigen (PSA) and creatinine levels, which could indicate the presence of prostate cancer and impaired kidney function, respectively.

The patient had a history of locally invasive prostate cancer even though he didn’t experience any symptoms of this disease.

Ultrasound examination showed an enlarged prostate plus obstructed ureters — the tubes that carry urine from the kidney to the bladder. To remove the obstruction, doctors inserted a thin tube into both ureters and restored urine flow.

After the procedure, the man had low levels of calcium, a depressed mood, and back pain, all of which compromised his recovery. Imaging of his back showed no obvious reason for his complaints, and he was discharged.

Eight days later, the patient went to the emergency room of a large public hospital because of back pain radiating to his left buttock. The man also had mild proximal weakness on both sides. He was thinner, and had low levels of calcium, high blood pressure and serum bicarbonate levels, plus elevated blood sugar. In addition, his depression was much worse.

A psychiatrist prescribed him an antidepressant called mirtazapine, and regular follow-up showed that his mood did improve with therapy.

A computed tomography (CT) scan revealed a 10.5 cm tumor on the prostate and metastasis on the lungs and liver. Further testing showed high serum cortisol and ACTH levels, consistent with a diagnosis of Cushing’s syndrome.

But researchers could not identify the ACTH source, and three weeks later, the patient died of a generalized bacterial infection, despite treatment with broad-spectrum antibiotics.

An autopsy revealed that the cancer had spread to the pelvic sidewalls and to one of the adrenal glands. Tissue analysis revealed that the patient had two types of cancer: acinar adenocarcinoma and small cell neuroendocrine carcinoma — which could explain the excess ACTH.

Cause of death was bronchopneumonia, a severe inflammation of the lungs, triggered by an invasive fungal infection.

Investigators believe there are things to be learned from this case, saying, “Neither the visceral metastases nor aggressive growth of the pelvic mass noted on imaging were typical of prostatic adenocarcinoma. [Plus], an incomplete diagnosis at death was the precipitant for a post-mortem examination. The autopsy findings were beneficial to the patient’s family and treating team. The case was discussed at a regular teaching meeting at a large tertiary hospital and, thus, was beneficial to a wide medical audience.”

Although a rare cause of ectopic ACTH synthesis, small cell prostate cancer should be considered in men presenting with Cushing’s syndrome, especially in those with a “mystery” source of ACTH overproduction.

“This case highlights the importance of multidisciplinary evaluation of clinical cases both [before and after death], and is a fine example of how autopsy findings can be used to benefit a wide audience,” the researchers concluded.

8 medical conditions that could cause sudden weight gain

Weight gain can be associated with hormonal conditions, mood disorders, or other physiological factors. A sudden and unexplained weight gain could be your body’s way of signalling an underlying medical issue that needs to be addressed. For the sake of health and long-term well-being, it is important to differentiate between a few harmless extra kilos and a fluctuation that could be hiding a bigger problem. You can only be certain after consulting a healthcare practitioner.

If the weighing scale says your numbers are up but you haven’t changed your eating and exercise habits, you might consider any of the 8 medical conditions:

1.     Hypothyroidism The American Thyroid Association reveals that one in eight women will develop a thyroid disorder during her lifetime. Hypothyroidism refers to an underactive thyroid. The thyroid controls several body functions and your metabolism is one of them. If you’re not producing enough thyroid hormone your body can’t burn as much energy. Symptoms appear throughout your system. They include: weight gain, exhaustion, drier skin, thinner hair, bloating, muscle weakness, constantly feeling cold, and constipation. Once diagnosis is confirmed a doctor can prescribe an oral replacement for thyroid hormone that can relieve symptoms within weeks.

2.     Polycystic ovary syndrome (PCOS) One in 10 women of childbearing age undergoes PCOS. It is an endocrine disorder characterised by an imbalance in the sex hormones oestrogen and testosterone.  This results in irregular periods, acne and even facial hair growth. The disorder also disrupts the way the body uses insulin — which is the hormone responsible for converting carbohydrates into energy. As a result the sugars and starches you consume are stored as fat instead of energy, thus, weight gain. PCOS has no cure but women who have it can manage their symptoms with lifestyle changes and medication. A doctor’s consultation will help you find an appropriate method.

3. Insomnia Avoid fake news! Subscribe to the Standard SMS service and receive factual, verified breaking news as it happens. Text the word ‘NEWS’ to 22840 Sleep deprivation can negatively impact both your metabolism and your hunger hormones. Sleeping too little increases ghrelin, the hormone that signals the body that it’s time to eat, while lowering leptin, the hormone that says you are full. The result: increased cravings and snacking to get more energy through the day. Insomnia increases impulsive eating. A 2018 study published in the American Journal of Clinical Nutrition found that the right amount of sleep could mean consuming up to 10 fewer grams of sugar throughout the day.

4.     Tumours Weight gain around your belly as opposed to your lower body or other areas can be more dangerous to your health. Large pelvic area tumours like uterine or ovarian tumours can inflate the abdomen the way excess fat does. In some cases they can also be cancerous. In addition to weight gain, symptoms of ovarian or uterine tumours include vaginal bleeding, lower back pain, constipation and painful intercourse. But these signs are common for other conditions as well so it‘s worth confirming with a doctor to rule out any possible complications.

5. Peri menopause and menopause Perimenopause -the transition period to menopause can start as early as a woman’s mid-thirties, but usually starts in their forties. This period triggers hormones like oestrogen to rise and fall unevenly, which can cue weight gain in some women. Genetics are a good starting point on how your body experiences these changes, so it would be helpful to look into how it affected your mother and other older women in your family. Other signs of perimenopause are mood swings, irregular periods, hot flashes, and changes in libido. Age also contributes to loss of muscle mass and increase in body fat. An Ob-Gyn should be able to talk you through these changes and recommend management options.

6.     Mood disorders Depression and anxiety can result in fatigue, lack of focus and irritability. Some people cope with anxious or sad feelings by mindlessly munching on food they don’t really need. Additionally chronic stress throws your body into fight-or-flight mode, leading to a surge of adrenaline, as well as a heavy dose of the hormone cortisol –responsible for restoring energy reserves and storing fat.

7. Cushing syndrome Sometimes tumours on the pituitary or adrenal glands can contribute to a condition known as Cushing’s disease which is characterised by high levels of cortisol in the blood. Taking long term steroids could also result in this disease. Patients with Cushing syndrome will experience rapid weight gain in the face, abdomen and chest. They also display slender arms and legs compared to the heavy weight in the core of the body. Other symptoms include: high blood pressure, mood swings, osteoporosis, discoloured stretch marks, acne, and fragile skin. Depending on the cause, Cushing‘s disease can be treated in a different ways.

8. New medication Before starting on any new prescription medication, ask your doctor if weight gain is a possible side effect. Birth control pills may lead to weight gain depending on the brand, dosage, and the person’s hormonal levels. Psychiatric medications, especially for depression and bipolar disorder, have been known to cause weight gain, as they target the brain. Similarly, taking insulin to manage diabetes or medications that treat high blood pressure can also lead to extra kilos, so staying active and sticking to a strict meal plan can help you take insulin without unnecessarily weight gain.

Cushing’s Patients at Risk of Life-threatening Pulmonary Fungal Infection

Cushing’s disease patients who exhibit nodules or masses in their lungs should be thoroughly investigated to exclude fungal infection with Cryptococcus neoformans, a study from China suggests.

While rare, the infection can be life-threatening, showing a particularly worse prognosis in patients with fluid infiltration in their lungs or with low white blood cell counts in their blood.

The study, “Cushing’s disease with pulmonary Cryptococcus neoformans infection in a single center in Beijing, China: A retrospective study and literature review,” was published in the Journal of the Formosan Medical Association.

Cortisol, a hormone that is produced in excess in Cushing’s disease patients, is a kind of glucocorticoid that suppresses inflammation and immunity. Consequently, subjects exposed to cortisol for long periods, much like immuno-compromised patients, are at high risk for infections.

In Cushing’s patients, the most common infections include Pneumocystis jiroveciAspergillus fumigatus, and Cryptococcosis — 95 percent of which are caused by C. neoformans.

But while “Cushing’s disease patients are susceptible to C. neoformans, the association between pulmonary C.neoformans and [Cushing’s disease] is poorly explored,” researchers said.

In an attempt to understand the clinical characteristics of Cushing’s patients who develop C.neoformans infections, researchers in Beijing, China, reviewed the clinical records of six patients at their clinical center.

Their analysis also included six other patients whose cases had been reported in previous publications.

Patients had a mean age of 44 and 10 were diagnosed initially with high blood pressure. Seven also had diabetes mellitus.

All patients had elevated cortisol levels in their urine and high levels of the adrenocorticotropic hormone (ACTH). Ultimately, all patients were found to have masses in their pituitary glands, causing the high cortisol and ACTH levels.

Patients complained of lung symptoms, including shortness of breath after physical activity, cough, and expectoration. But they had no fever or signs of blood in the lungs, which could suggest lung infection.

A CT scan of the chest then revealed lung nodules in four patients, and lung masses in five patients. Four patients, including one with a lung mass, also had lung air spaces filled with some material (pulmonary consolidation), which was consistent with pulmonary infection.

After analyzing lung nodule/mass biopsies, lung fluids, or blood samples, all patients were diagnosed with C. neoformans pulmonary cryptococcosis.

For their infection, patients received anti-fungal drugs, including amphotericin-B, fluconazole, flucytosine, and liposomal amphotericin. Cushing’s disease, however, was treated with surgery in 10 patients and ketoconazole in two patients.

Despite the treatments, five patients died during follow-up, including four who experienced co-infections or spreading of the cryptococcal infection and one patient with extensive bleeding after surgical removal of the gallbladder.

Among them, two patients had significantly low white blood cell levels and elevated cortisol levels, and four had infiltration in their lungs, suggesting these are markers of poor prognoses.

Researchers also noted that the patients who received ketoconazole died during in the reviewed studies. They attribute this to ketoconazole’s anti-fungal properties, which may interfere with its ability to manage Cushing’s symptoms.

Given the high susceptibility of Cushing’s disease patients to C. neoformans infections, “pulmonary nodules or masses should be aggressively investigated to exclude” this potentially fatal opportunistic infection, the researchers suggested.

“The infiltration lesions in chest CT scan and lymphopenia seem to be potential to reflect the poor prognosis,” they said.
